Treatment and frequency of follow-up of BCC patients in the Netherlands

Abstract

The incidence of Basal Cell Carcinoma (BCC) rises by 5% per decade in the Netherlands (1), representing an important burden on the health care system and dermatologists' workload (2,3). There is no evidence that intensive follow-up results in better outcomes (burden of disease, cosmetic results) in patients with low risk BCCs (4–6). According to the Dutch BCC guideline, follow-up after treatment is not indicated for patients with a low risk BCC (7), but patients may come for follow-up more frequently for various reasons (4,7,8). Considering the enormous amount of patients, extra follow-up visits represent a substantial workload and healthcare costs. Therefore, we studied follow-up of 482 BCC patients, diagnosed in 2010 from general hospitals (N=291 – random sample from a population-based cancer registry) and academic hospitals (N=191), who had a total of 578 BCC diagnosed in 2010. Information on medical history, tumor characteristics and the treatment and follow-up of all diagnosed BCCs was retrieved from the patient files until April 2015.

Immunohistochemical identification of nail matrix melanocytes

Abstract

Background

No previous studies have been conducted to determine the normal number of nail matrix melanocytes in Latin American individuals. The objective of this work was to determine the number of melanocytes per linear millimeter present in the nail matrix and the nail bed in samples obtained from Colombian individuals.

Methods

Twenty-six unilateral biopsies were taken from 19 cadavers subjected to clinical and medico-legal autopsies. These biopsy samples were processed with conventional histotechnology and immunohistochemistry (IHC) with anti-HMB-45 and anti-MiTF. Three sets of photographs (HE, HMB-45 and MiTF) were taken of each biopsy sample and independently assessed by three pathologists. Each observer counted the number of melanocytes present in 1 linear mm of the nail matrix or bed.

Results

We found an average of 4.6 melanocytes x linear mm with H & E staining, 9.8 with HMB-45 and 12.4 with MiTF.

Conclusions

The use of IHC significantly increases and facilitates the identification of melanocytes in unilateral biopsies. Our IHC counts exceed the averages found in the literature. This finding warrants new studies to verify whether the Colombian population presents higher numbers of melanocytes in the nail matrix than other populations or whether the observed increase is a result of the use of MiTF.

Patch Testing in Gastrointestinal Diseases – A Systematic Review of the Patch Test (PT) and Atopy Patch Test (APT)

Abstract

Food allergy is common and the prevalence is increasing. The pathogenesis of food allergy has been extensively reviewed. Immunologic and clinical tolerance to food requires production of regulatory T cells that are food-antigen specific. Loss of tolerance to food can lead to IgE-mediated reactions and non-IgE-mediated reactions.

Reply to: Kubiak K. And al. Endosymbiosis and its significance in dermatology

Abstract

We would like to begin by congratulating Kubiak K et al on their work[1], which has the potential to contribute to review the question of endosymbiosis and its significance.We would like to add some new data, notes and comments. Some data regarding viral endosymbiosis other than those discussed by the authors, showed the transmission of a Gemycircularvirus - Sclerotinia sclerotiorum hypovirulence-associated DNA1- like virus (SsHADV-1–LV)- via insect vectors - Lycoriella ingenua.

The iris signal: blue periphery, tan collaret and freckles pattern – strong indicators for epidermal skin cancer in South-Eastern Europe

Abstract

Background

Eye and skin share the embryological origin. Both are established risk factors in epidermal skin cancer. There are few reports using iris colour classification scales, most of them analyse colour in general or are too complex to use in daily practice.

Objectives

To investigate which iris colour pattern is associated with epidermal skin cancer in a S-E European Caucasian population.

Methods

A case control study was conducted on 480 patients: 229 skin cancers patients and 251 controls (dermatological patients free of skin cancers), admitted in two medical clinics of Dermatology in Bucharest, between October 2011 and May 2014. High resolution iris photos were taken for each patient. Three parameters of the iris were analysed individually and in association for each patient: periphery, collaret and freckles.

Results

The most frequent iris colour pattern associated with epidermal skin cancer was blue periphery with light brown collaret and freckles present. In terms of individual parameters, the strongest indicators for skin cancer patients were blue periphery and blue collaret.

Conclusions

The results of this study sustain the hypothesis that blue periphery with light brown collaret and freckles iris pattern is a reliable phenotypic marker for epidermal skin cancer. The results of this study differ from previous reports in which skin cancer risk was associated with a homogenous blue iris. We account these differences to the characteristics of the recruited patients (S-E European, skin type II and III). The assessment of iris colour patterns is an easy and inexpensive detection tool in skin cancer risk assessment.

5 alpha-reductase inhibitor treatment for frontal fibrosing alopecia: An evidence-based treatment update

Abstract

Background

Treatment for frontal fibrosing alopecia (FFA) is challenging and its treatment regimen often mirrors other lymphocytic-predominant cicatricial alopecia. 5 alpha-reductase inhibitor (5ARI) has been reported with some treatment success in severe cases of FFA.

Objective

To carry out evidence-based analysis of articles published on treatment efficacy and safety of 5 alpha-reductase inhibitor for the treatment of FFA.

Methods

Articles published on the use of 5ARI to treat FFA between 2005 to 2017 were reviewed, analysed and graded according to the American College of Physicians outcome study grading system.

Results

There were two studies with moderate-level of evidence that described the efficacy of 5ARI for treatment of FFA. 5ARI was commonly used as adjunctive therapy with positive results in recalcitrant disease. Mild to moderate hair regrowth was reported in one grade 2 and three lower grade (one grade 3 and two grade 4) studies. There is limited evidence on the safety aspects of this medication in most studies that were analysed.

Limitations

Database studies might not fully account for confounders and is subjected to variations in methodology and data collection.

Conclusion

This review demonstrated that FFA patients treated with 5ARI could achieve either disease stability or reduction in the rate of progression in selected cases. A well designed randomised, double-blind, controlled study would strengthen the role of 5ARI as part of treatment armamentarium for FFA.

Long-Term Optimization of Outcomes With Flexible Adalimumab Dosing in Patients With Moderate to Severe Plaque Psoriasis

Abstract

Background

The recently updated dosing recommendation for adalimumab for moderate to severe plaque psoriasis states that patients with inadequate response to adalimumab every other week (EOW) after 16 weeks may benefit from an increase in dosing frequency to 40 mg every week (EW).

Objective

To determine the long-term efficacy of adalimumab in patients with psoriasis with flexibility to escalate and de-escalate between EOW and EW dosing.

Methods

Data from an open-label study in patients with psoriasis who had received adalimumab in phase 2/3 studies and their extensions were included. Patients initially received 40 mg adalimumab EOW for 24 weeks. From weeks 24 to 252, patients whose Psoriasis Area and Severity Index response was <50% (PASI 50) could be dose-escalated to 40 mg EW and were re-evaluated at 6 and 12 weeks and then every 12 weeks thereafter. Patients who dose-escalated and achieved a PASI 75 response were de-escalated to EOW and could re-escalate to EW if response fell below PASI 50 again; no further de-escalation was allowed. Changes in PASI scores were reported at the last visit before dose escalation or de-escalation.

Results

By week 24, 64.1% of patients in the overall population (n=1256) achieved ≥PASI 75 response, 40.3% ≥PASI 90 response, and 21.7% PASI 100 response. Patients who had a <PASI 50 during weeks 24 to 252 (349/1256, 27.8%) were dose-escalated to EW; 182 (52.1%) remained on EW dosing and 167 (47.9%) achieved a PASI 75 response and were de-escalated to EOW; 83 patients were later re-escalated to EW dosing owing to a <PASI 50 response. Dose escalation was not associated with additional safety concerns.

Conclusion

Optimizing therapy by temporarily increasing the dosing of adalimumab to EW in patients with psoriasis and an inadequate response to adalimumab 40 mg EOW permitted the achievement and long-term maintenance of clinical improvement.

Major prognostic factors for recurrence and survival independent of the American Joint Committee on Cancer eighth edition staging system in patients with cutaneous squamous cell carcinoma treated with multimodality therapy

Abstract

Background

The purpose of this study was to assess changes resulting from the American Joint Committee on Cancer (AJCC) eighth edition for cutaneous squamous cell carcinoma (SCC) and evaluate pertinent excluded factors.

Methods

In 101 patients receiving surgery and postoperative radiation, recurrence and survival were estimated by cumulative incidence and Kaplan-Meier method. Time-to-event analysis was performed using Cox proportional hazards and Fine-Gray competing risks regression models.

Results

The 2-year locoregional recurrence, overall survival (OS), and cause-specific mortality rates were 25%, 72%, and 13%, respectively. The AJCC eighth edition upstaged T classification in 50% of patients and overall stage in 39%. In multivariate analysis, immunosuppression and in-transit metastasis were associated with locoregional recurrence. Older age and in-transit metastasis were associated with worse OS. In univariate analysis (limited by number of events), cause-specific mortality was associated with positive margin, in-transit metastasis, and the seventh edition dichotomized T classification and overall stage.

Conclusion

In-transit metastasis was significantly associated with locoregional recurrence, OS, and cause-specific mortality. Efforts should be made to define in-transit metastasis in the staging system.

Blunt cannula subcision is more effective than Nokor needle subcision for acne scars treatment

Summary

Background and aim

A comprehensive study comparing two different modalities, Nokor needle subcision (NNS) and blunt cannula subcision (BCS), for treatment of acne scars, has not been reported previously. The aim was to compare the effectiveness of these two methods based on patient's and doctor's satisfaction measures, in addition to the late complications 3 months postsubcision.

Method of intervention

Patients had 18-65 years old, with acne scars on both malar sides. They were treated at one malar side with NNS and with BCS at another side. They were monitored during the first week, at one and 3 months postintervention. Patient's and two dermatologist's satisfactions were compared during 3 months, for each modality and between modalities.

Results

From 34 patients, 29.4%, 55.9%, and 14.7% had mild, moderate, and severe acne scars, respectively. Ecchymosis, nodule formation post-NNS, and edema after BCS were the complications. Patients were satisfied with BCS during 3-month monitoring (P = .021), but not with NNS (P = .353). Physician-1 was satisfied from the outcome of both BCS and NNS procedures (P = .044 and .006, respectively). However, physician-2 was only satisfied with NNS at the month 3 than the month 1 (P = .002). All patients and physicians were significantly more satisfied with BCS than NNS (P = .000). Anyway, at the month 3, physician-2 had no significant different points of view about applied methods (P = .25).

Discussion

Considering the complications and satisfaction rates, BCS was more efficient than NNS for acne scar treatment. Then, we suggest BCS as a good replacement for NNS.

Clinical evaluation of simultaneously applied monopolar radiofrequency and targeted pressure energy as a new method for noninvasive treatment of cellulite in postpubertal women

Summary

Introduction

This study investigates noninvasive cellulite treatments based on simultaneous application of monopolar radiofrequency (RF) and targeted pressure energy to evaluate efficacy and safety and to see whether simultaneous application has any benefits in noninvasive cellulite treatments.

Methods

Thirty women with cellulite (fibrous/adipose/aqueous types) received 4 gluteofemoral treatments (~24 minutes; ~1000 cm²) using a simultaneous application of RF and targeted pressure energy. Clinical improvement was assessed using a pentile grading scale and satisfaction questionnaires. Hip/thigh circumference was measured. Ultrasonography and thermography observed changes in dermal/subcutaneous tissue composition and in gluteofemoral thermal profile. Evaluation at 3 months posttreatment was compared against the baseline.

Results

The clinical improvement averaged 2.17 ± 0.95 (54% improvement). Cellulite was reduced in 93% of cases, while 73% of patients showed good/very good/excellent improvement, with most significant improvement seen in patients with moderately severe cellulite. Hips and thigh circumference decreased on average by 2.31 cm and 2.13 cm, respectively (P < .001). Patient satisfaction was very high, averaging 4.47 ± 0.57 points (1-5 scale). Ultrasonography revealed smoothing and thickening (+0.28 ± 0.15 mm) of the dermis and an average reduction of 1.96 ± 1.60 mm in fat thickness (P < .05). Subjects with significant cellulite reduction had a more homogenous thermal profile at follow-up as a result of therapy-induced diminution of topographic skin defects. No adverse events were recorded.

Conclusion

The application is effective and safe for treating cellulite. The level of clinical improvement after 4 sessions is comparable to results reported after 6-20 sessions in studies on stand-alone RF/laser/targeted pressure energy devices. The technology is promising and deserves further attention and research.

Antiaging and antioxidant effects of topical autophagy activator: A randomized, placebo-controlled, double-blinded study

Summary

Background

Recently, potential roles of autophagy in skin homeostasis received many interests. But, little has been reported for the potential antiaging effects of autophagy activator.

Objective

With the newly synthesized autophagy activator, heptasodium hexacarboxymethyl dipeptide-12 (Aquatide™) in vitro and clinical efficacy of the topical autophagy activator as an antiaging cosmeceutical ingredient was evaluated.

Methods

Antioxidant effect of Aquatide™ was evaluated by radical scavenging assay. In vitro effect was assessed by measuring the cytotoxicity of hydrogen peroxide in cultured normal human epidermal keratinocytes. Clinical evaluation was performed by a randomized, placebo-controlled, double-blinded study. Antioxidant efficacy was observed by measuring the carbonylated proteins in stratum corneum (SC) by fluorescein-5-thiosemicarbazide (FTZ) staining.

Results

Radical scavenging effects of Aquatide were observed with the ABTS assay, and significant reduction in hydrogen peroxide-induced cytotoxicity was observed in Aquatide™-treated cells. Autophagy inhibitor treatment abrogated cytoprotective effects of Aquatide™. In a clinical study, statistically significant increase in skin elasticity was observed after 4 and 8 weeks. Quantitative analysis of carbonylated proteins in SC also showed significant reduction in Aquatide™-treated group, which is consistent with the in vitro data.

Conclusion

These results suggest that autophagy plays important roles in antioxidant system and aging process in skin, and topical autophagy activators can be potential cosmeceutical ingredients for skin antiaging.

Should all patients with hyperparathyroidism be screened for a CDC73 mutation?

Summary

Primary hyperparathyroidism (PH) is a common endocrine abnormality and may occur as part of a genetic syndrome. Inactivating mutations of the tumour suppressor gene CDC73 have been identified as accounting for a large percentage of hyperparathyroidism-jaw tumour syndrome (HPT-JT) cases and to a lesser degree account for familial isolated hyperparathyroidism (FIHP) cases. Reports of CDC73 whole gene deletions are exceedingly rare. We report the case of a 39 year-old woman with PH secondary to a parathyroid adenoma associated with a large chromosomal deletion (2.5 Mb) encompassing the entire CDC73 gene detected years after parathyroidectomy. This case highlights the necessity to screen young patients with hyperparathyroidism for an underlying genetic aetiology. It also demonstrates that molecular testing for this disorder should contain techniques that can detect large deletions.

Learning points:

Necessity of genetic screening for young people with hyperparathyroidism.

Importance of screening for large, including whole gene CDC73 deletions.

Surveillance for patients with CDC73 gene mutations includes regular calcium and parathyroid hormone levels, dental assessments and imaging for uterine and renal tumours.

Interleukin-31 and interleukin-31 receptor–new therapeutic targets for atopic dermatitis

Abstract

Atopic dermatitis (AD) is characterized by chronic, eczematous, severe pruritic skin lesions caused by skin barrier dysfunction and T helper (Th)2 cell–mediated immunity. Interleukin (IL)-31 is a potent pruritogenic cytokine primarily produced by Th2 cells. Both IL-31 transgenic mice and wild-type mice treated with IL-31 exhibit AD-like skin lesions and scratching behaviour. IL-31 receptor α-chain (IL-31RA) are also expressed in peripheral nerves and epidermal keratinocytes, and the roles of IL-31 on pruritus and skin barrier have been investigated. Recently, an anti–IL-31 receptor antibody was shown to significantly improve pruritus in AD patients. This review focuses on IL-31 and IL-31RA in AD.

Intestinal-type adenocarcinoma of the sinonasal tract: an update

Purpose of review Intestinal-type adenocarcinoma (ITAC) is one of the most frequent sinonasal tumors, especially in European countries. The purpose of this article is to review the most recent literature, with special emphasis on biological and genetic profile and treatment guidelines. Recent findings Results on large series support transnasal endoscopic surgery as the technique of choice in the large majority of patients with ITAC. Adjuvant radiotherapy is recommended in advanced-stage and high-grade lesions. More robust data are required to confirm that early-stage, low-grade lesions can be treated with exclusive surgery. The efficacy of new chemotherapy and biotherapy regimens and the added value of heavy particle radiotherapy are currently under evaluation. With a 5-year overall survival ranging between 53 and 83%, which is mainly impacted by local recurrences, ITAC requires a more detailed understanding of its biology. Genetic and biological studies have identified alterations in the molecular pathways of EGFR, MET, and H-RAS which might be considered as potential targets for biotherapy. Summary Surgery still plays a key role in the treatment of ITAC, but multidisciplinary management is mandatory. Although further validation is needed, the role of nonsurgical treatment strategies is rising, in agreement with the progresses made in the biological profiling of the disease.

Reducing morbidity and complications after major head and neck cancer surgery: the (future) role of enhanced recovery after surgery protocols

Purpose of review To review the development and the benefits of enhanced recovery after surgery (ERAS) protocols in non-head and neck disciplines and to describe early implementation efforts in major head and neck surgeries. Recent findings Several groups have adopted ERAS protocols for major head and neck surgery and demonstrated its feasibility and effectiveness. Summary There is growing evidence that clinical and financial outcomes for patients undergoing major head and neck surgery rehabilitation can be significantly improved by standardizing preoperative, intraoperative, and postoperative treatment protocols. Current experience is limited to single centers. A future goal is to broaden the adoption of ERAS in head and neck surgical oncology to include national and international collaboration, data sharing, and learning.

Salivary duct carcinoma

Purpose of review The review puts new information on geno- and phenotype of salivary duct carcinoma (SDC) in the perspective of the updated 2017 WHO classification. Recent findings The proportion of SDC is increasing. This may be because of a true rise in incidence, but certainly to better diagnostic tests and changed WHO definitions. In this light, a substantial proportion of carcinoma expleomorphic adenoma is now attributed to the category of SDC. 'Low-grade SDC' and 'SDC in-situ' of the former WHO classification, are now named low-grade and high-grade intraductal carcinoma (IDC), respectively. Recent series quantify biologic aggressiveness: perineural growth, vascular invasion, and extracapsular extension in lymph node metastasis are each observed in two out of three patients with SDC. Most patients die within 3 years, but once 5-year disease-free survival is reached, further disease activity is exceptional. The typical molecular biological profile with high human epidermal growth factor receptor 2 and androgen receptor expression is increasingly successfully exploited in clinical trials for advanced SDC. Summary The aggressive SDC is increasingly diagnosed. Despite intensive combined surgery and radiation therapy, many patients recur, for whom new bullets, targeting the molecular biological mechanisms, are the subject of ongoing clinical trials.

Nature and role of surgical margins in transoral laser microsurgery for early and intermediate glottic cancer

Purpose of review Summarize recent findings regarding the impact of margin status on oncologic outcomes and organ preservation, as well as evaluate possible management policies of close and positive margins after transoral laser microsurgery (TLM) for Tis-T2 glottic carcinomas. Recent findings Impact of margin status on survival rates remains controversial, whereas some authors found close and positive margins to be independent risk factors for recurrence and poorer survival rates, others did not find any significant variations compared with negative ones. A common trend can be observed in performing a watchful waiting policy or second look TLM in patients with close-superficial and positive single-superficial margins. Further treatment seems preferable in case of deep and positive multiple superficial margins. Summary Positive margins are present in up to 50% of patients treated by TLM, even though a high rate of false positivity, reaching 80%, has been described. Close and positive single superficial margins seem to be linked to higher recurrence rates compared with negative margins, even though watchful wait and see policy, especially when performed by adjunctive visual aids like Narrow Band Imaging, maintains good final oncological and organ preservation outcomes. Further treatments are required in case of deep margin positivity.

Free flaps for head and neck cancer in paediatric and neonatal patients

Purpose of review To review recent literature on the subject of free tissue transfer options in paediatric head and neck surgery, with a particular emphasis on highlighting the advantages and disadvantages of different reconstructions in the paediatric patient. Recent findings Free tissue transfer in paediatric patients is predictable and applicable for a wide range of congenital and acquired defects in the head and neck. The free fibula flap is a mainstay of mandibular reconstruction and allows excellent implant-supported prosthodontic rehabilitation and growth potential at the recipient site with little or no donor site morbidity. Other less commonly explored options include the deep circumflex iliac artery flap, scapula flap and medial femoral condyle flap. The gracilis mucle remains the mainstay for facial reanimation with other options including pectoralis minor, rectus abdominis, extensor digitorum brevis and latissimus dorsi. There are compelling arguments for centralization of services and creative strategies in postoperative rehabilitation (e.g. play therapy). Summary Free flaps in paediatric patients are a viable option and may even have advantages relative to adults because of the absence of atherosclerosis, purported lower risk of vasospasm and proportionally larger vessel size. Transfer earlier in life maximizes functional potential and 'normalizes' treatment.

Oncologic and functional outcomes of patients treated with transoral CO2 laser microsurgery or radiotherapy for T2 glottic carcinoma: a systematic review of the literature

Purpose of review To give an overview of the laryngeal preservation and functional outcomes of patients treated with transoral CO2 laser microsurgery (TLM) or radiotherapy for T2 glottic carcinoma. This information supports physicians and patients in treatment counselling and choices. Recent findings A recent systematic review showed that local control rates at 5-year did not differ between radiotherapy and TLM for T2 glottic tumours. However, there is a lack of comparative data on laryngeal preservation as well as functional outcomes in T2 glottic carcinoma. Summary Laryngeal preservation for T2 tumours in this review is higher for patients treated primarily with TLM (88.8 vs. 79.0%). It is important to differentiate between tumours with normal and impaired mobility (T2a and T2b) because the latter showed poorer prognosis for both TLM and radiotherapy. Involvement of the anterior commissure does not result in significantly lower oncological results, if adequately staged and treated. More studies are needed to support these data and to compare the functional outcomes between TLM and radiotherapy for T2 glottic carcinoma.

Synovial sarcomas of the upper aero-digestive tract: is there a role for conservative surgery?

Purpose of review To present the current state of knowledge concerning the role of conservative surgery in the treatment of synovial sarcomas of the upper aero-digestive tract (UADT). Recent findings The wider experience on synovial sarcomas involving the extremities and the results of retrospective reports focused on head and neck synovial sarcomas tend to justify a conservative surgical approach when dealing with tumors involving the UADT. Summary UADT synovial sarcomas is an extremely rare clinical entity (only around 50 cases reported in the literature, with four more herein presented from our own surgical series), with no clear guidelines concerning its treatment. Resection should be aimed to an en-bloc removal of the tumor within uninvolved surgical margins. In fit patients, a conservative surgical approach should be preferred if it does not interfere with a complete resection and reasonable functional outcomes. Adjuvant treatments (radiotherapy and/or chemotherapy) are frequently needed in view of the aggressive behavior of such tumor, but they should be balanced according to patient's characteristics and tumor risk factors (grade, size, and previous treatments).

Orbital exenteration for sinonasal malignancies: indications, rehabilitation and oncologic outcomes

Purpose of review Review the recent literature regarding the management of orbital invasion in sinonasal malignant tumors. Recent findings There is a recent trend in preserving the orbit in cases of minimal invasion of periosteum and limited periorbit involvement, as well as in presence of good response to neoadjuvant chemotherapy, mainly in squamous cell carcinoma and neuroendocrine histologies. Summary The decision about orbital exenteration in cases of sinonasal malignancies is facilitated if the patient already has clear clinical signs of intraconal invasion such as visual loss, restriction of ocular mobility or infiltration of the eyeglobe. However, in borderline situations, confirmation of orbital involvement should be performed intraoperatively. In selected cases with minimal orbital invasion without functional compromise, orbit sparing surgery can be done with acceptable oncological outcomes.

Detection of surgical margins in oral cavity cancer: the role of dynamic optical contrast imaging

Purpose of review The quantity of tissue removed during an oncologic surgical procedure is not standardized and there are numerous reports of local recurrence despite histologically adequate resection margins. The oral cavity is one of the sites in the head and neck with high chances of recurrence following negative margins. To address this need, this article reviews the recent applications of Dynamic Optical Contrast Imaging (DOCI) towards both oral screening and the intraoperative evaluation of tumor margins in head and neck surgery. Recent findings Human ex-vivo and in-vivo trials suggest DOCI is well tolerated, low-cost, and sensitive for differentiating cancerous from normal tissues throughout the head and neck, in addition to the oral cavity. Ex-vivo imaging of OSCC specimens generated histologically verified image contrast. Furthermore, in-vivo intraoperative results demonstrate significant potential for image-guided detection and resection of oral cavity squamous cell carcinoma (OSCC). Summary DOCI augments tissue contrast and may enable surgeons to clinically screen patients for oral cancer, make histologic evaluations in vivo with fewer unnecessary biopsies, delineate clinical margins for tumor resection, provide guidance in the choice of biopsy sites, and preserve healthy tissue to increase the postoperative functionality and quality of life of the patient.

The recurrent pleomorphic adenoma conundrum

Purpose of review Recurrent pleomorphic adenoma (RPA) is uncommon. Treatment selection is based on the likely possibility of minimizing the risk of tumour recurrence, avoiding local functional and cosmetic sequelae, and eradicates the possibility of metastatic or malignant transformation. Much has changed since the topic was reviewed in 2001, and this manuscript comments on clinical progress and discusses patient treatment options. Recent findings Surgery is the preferred treatment for head and neck pleomorphic adenoma. Over the recent decade the surgical radicality is favoured for parotid and submandibular gland pleomorphic adenoma, from total gland and tumour removal to endoscopic or minimal open extracapsular tumour excision. Currently molecular pathology and biomarker research has not identified any evidence that separates pleomorphic adenoma from RPA, thus supporting that tumour recurrence is likely associated with surgery. Revision surgery has been reported to be frequently noncurative depending on the extent of the primary surgery, with the added risk of local cosmetic and functional sequelae. Radiotherapy as a nonsurgical modality has advanced and has been shown to be effective in controlling, if not curing, high-risk patients who have identifiable prognostic factors of developing a recurrence and patients with RPA. Summary Current surgical management of pleomorphic adenoma is associated with improved quality of life and minimal disturbance to cosmetic and functional. The reported incidence of RPA has been reduced by 'expert surgeons' but with limited short-term follow-up following more recent surgical modifications. Patients with RPA should be offered treatment that includes surgery and/or radiotherapy and should be encouraged to partake of this decision making process.

Impact of 3D virtual planning on reconstruction of mandibular and maxillary surgical defects in head and neck oncology

Purpose of review This review describes the advances in 3D virtual planning for mandibular and maxillary reconstruction surgical defects with full prosthetic rehabilitation. The primary purpose is to provide an overview of various techniques that apply 3D technology safely in primary and secondary reconstructive cases of patients suffering from head and neck cancer. Recent findings Methods have been developed to overcome the problem of control over the margin during surgery while the crucial decision with regard to resection margin and planning of osteotomies were predetermined by virtual planning. The unlimited possibilities of designing patient-specific implants can result in creative uniquely applied solutions for single cases but should be applied wisely with knowledge of biomechanical engineering principles. Summary The high surgical accuracy of an executed 3D virtual plan provides tumor margin control during ablative surgery and the possibility of planned combined use of osseus free flaps and dental implants in the reconstruction in one surgical procedure. A thorough understanding of the effects of radiotherapy on the reconstruction, soft tissue management, and prosthetic rehabilitation is imperative in individual cases when deciding to use dental implants in patients who received radiotherapy.

Immunotherapy for recurrent/metastatic head and neck cancer

Purpose of review In the last decade, after cetuximab (anti-epidermal growth factor receptor), none of the novel investigated compounds has demonstrated benefit in head and neck squamous cell cancers (HNSCC), both in advanced and curative settings. Therefore, prognosis of recurrent/metastatic (R/M) HNSCC patients remains dismal, especially in platinum-refractory cohort. In the last few years, a new important class of drugs has affirmed its role. HNSCC, even if less 'immunogenic' than other malignancies (e.g. melanoma), was field of application of several new immune agents. To date, the most important data regard drugs acting on PD-1 (programmed death-1)/PD-L1 (programmed death-ligand 1) axis that is a crucial checkpoint used by tumor for immune escape. Our purpose is to summarize the results of these PD-1/PD-L1 inhibitors, outlining some critical points and few practical suggestions. Recent findings Nivolumab was recently approved by main regulatory agencies as second-line treatment for platinum-refractory R/M HNSCC. In the same setting, pembrolizumab was approved by FDA. Atezolizumab and durvalumab have already showed similar benefit in phase Ia and II studies, respectively. Summary Anti-PD1/PD-L1 agents are new effective therapies in R/M HNSCC. Their combination with conventional/novel compounds, as well as a better selection of responding patients, could lead to improve current results.

Improvement of skin lesions and life quality in moderate-to-severe eczema patients by combined TCM therapy

Atopic Dermatitis (AD) is a common allergic inflammatory skin disorder exacting up to $3.8 billion health dollars annually for treatment.1 50.4% of AD patients report using complementary and alternative therapies, such as Traditional Chinese Medicine (TCM); but reports on TCM efficacy and safety remain inconclusive.2, 3 We were interested to learn if combined TCM therapy could suppress Th2 inflammation and benefit patients with AD. We report a case series of 14 AD patients treated with this approach and analysis of the TCM herbs in murine and in vitro models.

Congenital dacryocystocele is a relatively rare oculonasal anomaly which can result in symptomatic obstruction of the nasolacrimal system. Techniques utilized in the management of this condition include nasolacrimal duct probing, endoscopic dacryocystorhinostomy, and transnasal marsupialization. Operative adjuncts include balloon dacryocystoplasty, bicanalicular silastic intubation, and intranasal stenting. Recurrence is relatively uncommon and can be addressed with the application of long-term nasolacrimal stenting.

Columellar Reconstruction in Children

Publication date: Available online 9 March 2018

Author(s): Kristen S. Pan, Brian S. Pan
Defects of the nasal complex can cause significant functional and psychosocial impairment. Nasal reconstruction aims to restore the normal trilaminar structure of the nose, which includes the internal lining, cartilaginous framework, and soft tissue envelope. Among the nasal subunits, the columella is especially challenging to reconstruct due to its unique contour and composite nature. Multiple techniques have been described, each carrying distinct advantages and disadvantages; however, the optimal procedure for an isolated defect of the columella remains elusive. The ideal reconstructive technique should recreate the contour of the columella, provide nasal tip projection, and maintain external valve patency. Additional considerations include matching the pigmentation and texture of the nasal skin while minimizing donor site morbidity. The authors recommend a two-stage reconstruction with bilateral nasal sill flaps and an auricular composite graft.

Congenital nasal pyriform aperture stenosis is a rare developmental anomaly, which is considered a variant of holoprosencephaly. It is characterized by a pyriform aperture width of 11mm or less on maxillofacial computed tomography, and is frequently associated with a solitary median maxillary central incisor. It presents with cyclical cyanosis, feeding difficulty, and respiratory distress. Conservative management includes nasal decongestant, saline and steroid drops, or a McGovern nipple. When conservative management fails, surgical intervention is indicated. Various methods of surgical repair have been described, two of which – nasal dilation and bone resection via a sublabial approach - are described in this article. The role of postoperative stenting is also discussed.

ObjectiveClinical studies demonstrating the prognostic factors in submandibular gland carcinoma are limited because the tumor is relatively rare. The aim of this study was to identify clinical outcomes and prognostic factors in submandibular gland carcinoma.MethodsThe study included 65 patients with submandibular gland carcinoma who underwent initial surgical treatment at the Kyoto University and its affiliated hospitals.ResultsThe 3-year overall survival (OS), disease specific survival, locoregional control (LRC), and no distant metastasis (NDM) rates were 74.2%, 74.2%, 90.0%, and 64.8%, respectively. In the current follow-up study, 16 patients died of the disease, 5 patients were alive with recurrence, 43 patients were alive without disease, and 1 patient died of unrelated disease without recurrence. All patients who died of the disease had developed distant metastasis. Based on univariate analysis, tumor grade (high grade) and lymph node metastases (≥N2) were significant prognostic factors for OS and LRC. It also revealed tumor grade (high grade), T classification (≥T3), and lymph node metastases (≥N2) were significant for distant metastasis. Multivariate analysis showed the following significant prognostic factors: lymph node metastases (≥N2) for OS, LRC, and NDM, and high tumor grade for NDM.ConclusionOur study suggested death of submandibular gland carcinoma occurred mainly due to distant metastasis. The significant predictors of distant metastasis were lymph node metastases (≥N2) and tumor grade (high grade).

Combined human papillomavirus typing and TP53 mutation analysis in distinguishing second primary tumors from lung metastases in patients with head and neck squamous cell carcinoma

Abstract

Background

In head and neck squamous cell carcinoma (HNSCC), the occurrence of concurrent lung malignancies poses a significant diagnostic challenge because metastatic HNSCC is difficult to discern from second primary lung squamous cell carcinoma (SCC). However, this differentiation is crucial because the recommended treatments for metastatic HNSCC and second primary lung SCC differ profoundly.

Methods

We analyzed the origin of lung tumors in 32 patients with HNSCC using human papillomavirus (HPV) typing and targeted next generation sequencing of all coding exons of tumor protein 53 (TP53).

Results

Lung tumors were clearly identified as HNSCC metastases or second primary tumors in 29 patients, thus revealing that 16 patients had received incorrect diagnoses based on clinical and morphological data alone.

Conclusion

The HPV typing and mutation analysis of all TP53 coding exons is a valuable diagnostic tool in patients with HNSCC and concurrent lung SCC, which can help to ensure that patients receive the most suitable treatment.

Patterns of recurrence in oral tongue cancer with perineural invasion

Abstract

Background

Although perineural invasion (PNI) is recognized as an adverse prognostic factor in oral tongue squamous cell carcinoma (SCC), the patterns of failure are poorly defined.

Methods

Patients with oral tongue SCC who received primary surgical treatment were identified. Specimens were reviewed by head and neck pathologists. Disease-specific survival (DSS) and locoregional recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), and distant recurrence-free survival (DRFS) were calculated. The PNI and PNI characteristics were analyzed as predictors of outcome. The utility of grading the extent of PNI was assessed by quantifying the number of PNI foci per slide reviewed, nerve caliber, and percent circumference involved.

Results

Patients with PNI had a decreased DSS; however, PNI was not predictive of LRFS or RRFS. Patients with PNI were more likely to develop a distant recurrence and 19.40 (confidence interval [CI] 6.70-56.14; P < .001) were more likely to develop a distant recurrence if PNI foci density was >1.

Conclusion

The presence of PNI in oral tongue SCC predicts worse DSS, with distant recurrence as the most common pattern of failure. High PNI foci density is associated with worse DRFS.

Polyethylene glycol fusion associated with antioxidants: A new promise in the treatment of traumatic facial paralysis

Abstract

Background

Recent studies in invertebrates have taught us that early cell membrane regeneration is determinant for axonal recovery and survival after trauma. Many authors obtained extraordinary results in neural regeneration using polyethylene glycol fusion protocols, which also involved microsutures and antioxidants.

Methods

Sixty rats were evaluated with functional and histological protocol after facial nerve neurotmesis. Groups A and B had their stumps coapted with microsuture after 24 hours of neurotmesis and groups C and D after 72 hours. In addition to the microstructure, groups B and D used the polyethylene glycol-fusion protocol for the modulation of the Ca⁺².

Results

At the sixth week, the latency of group D and duration of group B was lower than groups A and C (P = .011). The axonal diameter of the groups that used polyethylene glycol-fusion was higher than those who did not use polyethylene glycol-fusion (P ≤ .001).

Conclusion

Although not providing a functional improvement, polyethylene glycol-fusion slowed down demyelination.

Presence of lytic Epstein-Barr virus infection in nasopharyngeal carcinoma

Abstract

Background

Chromogenic Epstein-Barr virus-encoded RNA (EBER) in situ hybridization (EBER-ISH) is the gold standard to detect Epstein-Barr virus (EBV) but it is difficult to use in conjunction with immunohistochemistry (IHC). In this study, our purpose was to validate the sensitivity and specificity of RNAscope in detection of EBV infection in nasal epithelium and its stroma.

Methods

Fluorescence-based RNAscope EBER-ISH, BRLF1-ISH, and lineage marker-IHC were performed on archived formalin-fixed paraffin-embedded tissues from normal nasal cavity (n = 5), nasopharynx (n = 8), and nasopharyngeal carcinoma (NPC) specimens (n = 10).

Results

The EBERs were detected in 10 of 10 NPC samples but was absent in all normal tissues from the nasal cavity and nasopharynx. The EBERs were exclusively located in pan-cytokeratin (pan-CK)-positive tumor epithelial cells but not in CD45-positive leukocytes and vimentin-positive stromal fibroblasts. The level of EBER expression varied in tumor cells within patient and between patients as well. Additionally, 5 of 10 patients had positive BRLF-ISH.

Conclusion

We developed a simple and reproducible method to simultaneously detect mRNA and protein in formalin-fixed paraffin-embedded tissues of NPC. As a single staining, traditional EBER continues to be useful; however, for interpretation of the phenotype of EBV-infected cells, RNAscope is superior. Significantly, we showed that lytic EBV infection took place in NPC tumors.

Second primary squamous cell carcinoma in patients with nasopharyngeal carcinoma after radiotherapy predictors and prognostic factors

Abstract

Background

We investigated risk and prognostic factors for second primary squamous cell carcinoma (SCC) in patients with nasopharyngeal carcinoma (NPC) after radiotherapy (RT).

Methods

A total of 49 021 patients with NPC were treated at Sun Yat-Sen Cancer Center between January 1970 and December 2009. The incidence and management of second primary SCCs were analyzed.

Results

A total of 142 patients (0.29%) developed second primary SCC, with 78.2% in the upper aerodigestive tract. Older age, smoking, and chemotherapy were associated with an increased rate of second primary SCC. The 3, 5, and 10-year overall survival (OS) rates for second primary SCC were 47.18%, 31.69%, and 11.97%, respectively. Advanced age, family history of cancer, and treatment modality were independent prognostic factors for survival.

Conclusion

Second primary tumors rarely develop in patients with NPC treated with RT, but when this occurs, second primary SCC comprises a majority of these. Intensity-modulated RT may shorten the latency to second primary SCC. Surgery as the first-line treatment may improve survival and prognosis.

Treatment with anti-Sclerostin antibody to stimulate mandibular bone formation

Abstract

Background

Anti-Sclerostin antibody (Scl-Ab) is a promising new bone anabolic therapy. Although anti-Scl-Ab stimulates bone formation and repair in the appendicular and axial skeleton, its efficacy in the craniofacial skeleton is still poorly understood.

Methods

Using an established model of Down syndrome-dependent bone deficiency, 10 Ts65Dn mice and 10 wild-type mice were treated weekly via i.v. tail vein injection with vehicle or anti-Sclerostin for 3 weeks and euthanized 1 week after.

Results

Wild-type mice treated with the anti-Scl-Ab had increased mandibular bone, trabecular thickness, and alveolar height compared with controls. Anti-Scl-Ab increased Ts65Dn mandibular bone parameters such that they were statistically indistinguishable from those in vehicle-treated wild-type mandibles.

Conclusion

Treatment with anti-Scl-Ab significantly increased mandibular bone mass and alveolar height in wild type mice and normalized mandibular bone mass and alveolar height in Ts65Dn mice. The anti-Scl-Ab therapy represents a novel method for increasing mandibular bone formation.

Comparison of incidental versus palpable thyroid nodules presenting for fine-needle aspiration biopsy

Abstract

Background

Many attribute the rise in incidence of thyroid cancer to a deluge of radiologically identified incidental thyroid nodules. The clinical implications are unclear.

Methods

A review was performed of all patients who underwent fine-needle aspirations of thyroid nodules by our academic medical center's Endocrinology Division between 2006 and 2010. Medical records were reviewed to identify whether the thyroid nodule was discovered incidentally or by palpation.

Results

Of 1153 patients, 37.4% underwent a biopsy because of an incidental thyroid nodule. These patients were significantly more likely to be >45 years old, men, white race, and with a body mass index >30 kg/m². Of the 17.2% of incidentalomas that led to surgery, 8.5% were found to be thyroid cancer.

Conclusion

Thyroid nodules discovered incidentally are increasing the diagnosis of subclinical thyroid cancers. Not investigated previously, our study found that the mode of detection was not related to malignancy or surgery.

Skeletal muscle cells actively shape (auto)immune responses

Publication date: Available online 9 March 2018

Author(s): Ali Maisam Afzali, Thomas Müntefering, Heinz Wiendl, Sven G. Meuth, Tobias Ruck
Histopathological analyses of muscle specimens from myositis patients indicate that skeletal muscle cells play an active role in the interaction with immune cells. Research over the last few decades has shown that skeletal muscle cells exhibit immunobiological properties that perfectly define them as non-professional antigen presenting cells. They are able to present antigens via major histocompatibility complex molecules, exhibit costimulatory molecules and secrete soluble molecules that actively shape the immune response in an either pro- or anti-inflammatory manner. Skeletal muscle cells regulate both innate and adaptive immune responses and are essentially involved in the pathophysiological processes of idiopathic inflammatory myopathies. Understanding the role of skeletal muscle cells might help to identify new therapeutic targets for these devastating diseases. This review summarizes the immunobiological features of skeletal muscle cells, especially in the context of idiopathic inflammatory myopathies, and discusses shortcomings and limitations in skeletal muscle related research providing potential perspectives to overcome them in the future.

Clinical and experimental evidence for targeting CD6 in immune-based disorders

Publication date: Available online 9 March 2018
Source:Autoimmunity Reviews
Author(s): Marta Consuegra-Fernández, Feng Lin, David A. Fox, Francisco Lozano
CD6 is a cell surface glycoprotein expressed by most T cells and a subset of B cells that has incompletely-defined roles in regulation of lymphocyte development, selection, activation and differentiation. The two main known mammalian CD6 ligands, CD166/ALCAM and the very recently reported CD318, are widely expressed by both immune cells and a wide range of other cell types, including various epithelial and mesenchymal cell types, as well as many neoplasms. Moreover, CD6 is also a receptor for several pathogen- and damage-associated molecular patterns. Further layers of complexity of CD6 function are implied by the existence of multiple CD6 isoforms generated by alternative splicing of CD6 transcripts and soluble forms of CD6 released by proteases from the lymphocyte surface. Multiple lines of evidence are now emerging to implicate CD6 and its ligands in the pathogenesis and potentially the treatment of human autoimmune diseases, such as multiple sclerosis and psoriasis. CD6 is an important multiple sclerosis risk gene, and mice genetically deficient in CD6 or CD318, or treated with antibodies or chimerical proteins that interfere with CD6-ligand interactions, are protected from experimental allergic encephalomyelitis, a mouse model of multiple sclerosis. CD6 deficient mice also show reduced TH17 differentiation and protection from disease in a moue model of psoriasis, providing a foundation for successful clinical trials of an anti-CD6 monoclonal antibody (Itolizumab) in psoriasis. Here we review current knowledge about CD6 and its ligands, and consider its potential value as a therapeutic target in a range of immune-mediated disorders.

The role of capillaroscopy and thermography in the assessment and management of Raynaud's phenomenon

Publication date: Available online 9 March 2018
Source:Autoimmunity Reviews
Author(s): Ariane L. Herrick, Andrea Murray
Most patients with Raynaud's phenomenon (RP) have "benign" primary RP (PRP), but a minority have an underlying cause, for example a connective tissue disease such as systemic sclerosis (SSc). Secondary RP can be associated with structural as well as functional digital vascular changes and can be very severe, potentially progressing to digital ulceration or gangrene. The first step in management is to establish why the patient has RP. This short review discusses the role of nailfold capillaroscopy and thermography in the assessment of RP. Nailfold capillaroscopy examines microvascular structure, which is normal in PRP but abnormal in most patients with SSc: the inclusion of abnormal nailfold capillaries into the 2013 classification criteria for SSc behoves clinicians diagnosing connective tissue disease to be familiar with the technique. For those without access to the gold standard of high magnification videocapillaroscopy, a low magnification dermatoscope or USB microscope can be used. Thermography measures surface temperature and is therefore an indirect measure of blood blow, assessing digital vascular function (abnormal in both PRP and SSc). Until now, the use of thermography has been mainly confined to specialist centres and used mainly in research: this may change with development of mobile phone thermography.

The value of Autoimmune Syndrome Induced by Adjuvant (ASIA) - Shedding light on orphan diseases in autoimmunity

Publication date: Available online 9 March 2018
Source:Autoimmunity Reviews
Author(s): Yahel Segal, Shani Dahan, Kassem Sharif, Nicola Luigi Bragazzi, Abdulla Watad, Howard Amital
Autoimmune Syndrome Induced by Adjuvant (ASIA) is a definition aimed to describe the common etiological process at the root of five clinical entities sharing similar symptomatology: macrophagic myofasciitis syndrome (MMF), Gulf War Syndrome (GWS), sick building syndrome (SBS), siliconosis, and post vaccination autoimmune phenomena. ASIA illustrates the role of environmental immune stimulating agents, or adjuvants, in the instigation of complex autoimmune reactions among individuals bearing a genetic preponderance for autoimmunity. The value of ASIA lies first in the acknowledgment it provides for patients suffering from these as yet ill-defined medical conditions. Equally important is the spotlight it sheds for further research of these poorly understood conditions sharing a common pathogenesis.In this article we elaborate on the significance of ASIA, review the current evidence in support of the syndrome, and address recent reservations raised regarding its validity.

Author(s): Gabriela Recalde, Tamara Moreno-Sosa, Florencia Yudica, Cristian A. Quintero, Belén Sanchez, Graciela A. Jahn, Alexis M. Kalergis, Juan Pablo Mackern-Oberti
In this review we discuss how sex steroids and prolactin affect regulation and responsiveness of B and T cells. Sex hormones exert profound effects on several physiological processes of non- reproductive tissues. In the immune system, several studies with experimental models for SLE have shown a noticeable pro-inflammatory role for ERα, contributing to disease development reflected in proteinuria and renal pathology. On the other hand, ERβ appears to have an anti- inflammatory and immunosuppressive effect. Estrogen/ERα signaling induced an increase of Th17 cells in lymph nodes as well as the expression of its correspondent chemokine receptor CCR6 during collagen induced arthritis acute phase. High levels of anti- DNA antibodies and increased mortality was observed when given high E and prolactin doses to NZB/NZW mice, as compared with mice receiving low E and prolactin doses, or high E and low prolactin doses. Intracellular progesterone receptors have been detected in TCD4⁺ cells but in contrast as observed with ERs, it suppresses T cell dependent responses. Progestagen administration on female NZB/NZW mice decreased anti DNA IgG, improved survival, decreased glomerulonephritis and proteinuria.

A methodological review of induced animal models of autoimmune diseases

Publication date: Available online 8 March 2018
Source:Autoimmunity Reviews
Author(s): Xinhua Yu, Frank Petersen
Autoimmune disorders are characterized by a loss of immune tolerance and consequent autoimmunity-mediated disease manifestation. Experimental models are invaluable research tools helping us to understand disease pathogenesis and to search for novel therapeutics. Animal models of autoimmune diseases consist of two groups, spontaneous and induced models. In this review article, we focus on the induced models of autoimmune diseases. Due to the complex nature of autoimmune disorders, many strategies have been applied for the induction of corresponding experimental models in animals like monkeys, rabbits, rats, and mice. Methodologically, these strategies can be categorized into three categories, namely immunization with autoantigen, transfer of autoimmunity, and induction by environmental factors. In this review article, we aim to provide a comprehensive overview of the field of induced experimental autoimmune diseases. On the one hand, we describe and summarize the different strategies used for induction of experimental autoimmune disease. On the other hand, we discuss how to select a strategy for modeling human disease, including the choice of an appropriate species and method for such an approach.

Solid phase assays (SPAs) and automated microscope systems are increasingly used to screen for antinuclear antibodies (ANAs). The goal of this study was to evaluate the performance of three automated ANA screening assays; NOVA Lite HEp-2 using NOVA View® (NV, Inova Diagnostics), an automated indirect immunofluorescence method, EliA™ CTD Screen (Fluorescence Enzyme Immunoassay, FEIA; Thermo Fisher) and QUANTA Flash® CTD Screen Plus (Chemiluminescence immunoassay, CIA; Inova Diagnostics).The assays were performed on 480 diagnostic samples from patients with an ANA-associated rheumatic disease (AARD; systemic lupus erythematosus, primary Sjögren's syndrome, systemic sclerosis, inflammatory myopathy, mixed connective tissue disease) and on 767 samples from diseased and healthy controls.Using cut-offs proposed by the manufacturers, the sensitivity was 95%, 80.5% and 86% for NV, FEIA and CIA, respectively. The corresponding specificity was 61% (NV), 97.5% (FEIA) and 88% (CIA). The sensitivity associated with a specificity of ~95% was 79%, 82% and 78% for NV, FEIA, and CIA, respectively. Receiver operating characteristics (ROC) curve analysis revealed no differences in area under the curve (AUC) between the 3 assays when all diseases were grouped. For Sjögren's syndrome, the AUC was higher for SPAs than for NV, whereas for systemic sclerosis, the AUC was higher for NV than for CIA. For all assays, the likelihood ratio for AARD increased with increasing antibody levels and for double positivity of NV with SPA.In conclusion, the performance of automated SPA and IIF was assay- and disease-dependent. Taking into account antibody levels and combining IIF with SPA adds value.

Perspective: Scientific and ethical concerns pertaining to animal models of autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA)

Publication date: Available online 8 March 2018
Source:Autoimmunity Reviews
Author(s): Rohan Ameratunga, Daman Langguth, David Hawkes
The autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) was first described in 2011. The aluminium containing adjuvants of vaccines were stated to be one of the main causes of the condition. Other disorders associated with ASIA include siliconosis, Gulf war syndrome, sick building syndrome and the macrophagic myositis syndrome. We have recently reviewed ASIA as defined by its authors. We have shown that the definition of ASIA is imprecise and includes all patients with an autoimmune disorder as well as potentially the entire population. Application of the Bradford Hill criteria for causality does not support ASIA as an outcome of exposure to aluminium containing adjuvants in vaccines. The advocates of ASIA highlight animal models as evidence for the existence of the disorder. However, as this review will demonstrate, animal models purporting to support the existence of ASIA have methodological, analytical and ethical flaws which, in our view refute the existence of the condition. Three publications by the advocates of ASIA were recently retracted from peer-reviewed journals. We call for a moratorium on animal experiments of ASIA until an independent inquiry has been conducted to determine the existence of a clinically relevant syndrome, identifiable as ASIA in humans.

Cryoglobulins are immunoglobulins precipitating in cold condition. They are classified in 3 types according to the Brouet classification and may lead to vasculitis of small and medium size vessels. Vasculitis is related to vessel obstruction by monoclonal cryoglobulin aggregates in type I cryoglobulins and immune complex deposition in type II and III mixed cryoglobulins. This phenomenon is favored by low temperature, especially in skin, joints, and peripheral nerves, or increased cryoglobulin concentration in kidneys. For their detection, collection and clotting at 37 °C are critical pre-analytical conditions. Cryoglobulin characterization and quantification are important to identify the underlying disease. Since detection and identification of cryoglobulins lack standardization, a protocol for such detection, characterization and quantification is proposed.

IntroductionThe human glucocorticoid receptor gene (NR3C1) is considered to play a role in the differences and sensitivities of the glucocorticoid response in individuals with autoimmune diseases. The objective of this study was to examine by means of a systematic review previous findings regarding allelic variants of NR3C1 in relation to the risk of developing systemic autoimmune diseases.MethodsStudies that analysed the genotype distribution of NR3C1 allelic variants among patients with systemic autoimmune diseases were retrieved. A meta-analysis was conducted with a random effects model. Odds ratios (ORs) and their confidence intervals (CIs) were calculated. In addition, sub-analysis by ethnicity, sensitivity analysis and tests for heterogeneity of the results were performed.ResultsEleven studies met the inclusion criteria for meta-analysis. We found no evidence that the analysed NR3C1 polymorphisms, rs6198, rs56149945, and rs6189/rs6190, modulate the risk of developing a systemic autoimmune disease. Nonetheless, a protective role for the minor allele of rs41423247 was found among Caucasians (OR = 0.78; 95% CI: 0.65, 0.92; P = 0.004). A subgroup analysis according to underlying diseases revealed no significant association either for Behçet's disease or rheumatoid arthritis, while correlations between NR3C1 polymorphisms and disease activity or response to glucocorticoids could not be evaluated due to insufficient data.ConclusionsThere is no clear evidence that the analysed NR3C1 allelic variants confer a risk for developing systemic autoimmune diseases although the minor G allele of rs41423247 may be protective among Caucasians.

Evaluating Hearing Loss in Patients Undergoing Second Line Anti Tubercular Treatment

Abstract

To estimate the prevalence of Sensorineural hearing loss and evaluate the severity of hearing impairment in patients undergoing second line injectable antitubercular treatment. To study the effects of duration of treatment, dose schedule and demographic factors which aggravates anti TB drug induced ototoxicity. Design–prospective and retrospective study Setting-ENT & TB clinic at our hospital and TB Hospital of Subject-18–50 year age , diagnosed MDR or XDR TB Method–baseline puretone audiometry was done of all patients. all patients divided in 3 group depending on aminoacid (amikacin , kanamycin, capreomycin). Follow up PTA was done at 3rd month, 6th month and 6 month after stopping treatment 35.48% of Group 1 (kanamycin) patients show High frequency hearing loss and 16% of patient have both high and low frequency hearing loss High frequency hearing loss 21% of Group 2 (amikacin) patients show High frequency hearing loss and 5% of patient have both high and low frequency hearing loss 20% of Group 3 (capreomycin) patients show High frequency hearing loss with no patient resulted low frequency loss Patients treated FOR MDR-TB develop significant adverse effects. Clinicians must consider risk benefit analysis during treatment as ototoxicity of injectable aminoglycoside ATT is permanent. Early detection of hearing loss through pure tone audiometry helps preventing and progression of hearing loss without compromising the treatment.

New-onset atrial fibrillation: an update

Abstract

New-onset atrial fibrillation (NOAF) is the most common perioperative complication of heart surgery, typically occurring in the perioperative period. NOAF commonly occurs in patients who are elderly, or have left atrial enlargement, or left ventricular hypertrophy. Various factors have been identified as being involved in the development of NOAF, and numerous approaches have been proposed for its prevention and treatment. Risk factors include diabetes, obesity, and metabolic syndrome. For prevention of NOAF, β-blockers and amiodarone are particularly effective and are recommended by guidelines. NOAF can be treated by rhythm/rate control, and antithrombotic therapy. Treatment is required in patients with decreased cardiac function, a heart rate exceeding 130 beats/min, or persistent NOAF lasting for ≥ 48 h. It is anticipated that anticoagulant therapies, as well as hemodynamic management, will also play a major role in the management of NOAF. When using warfarin as an anticoagulant, its dose should be adjusted based on PT-INR. PT-INR should be controlled between 2.0 and 3.0 in patients aged < 70 years and between 1.6 and 2.6 in those aged ≥ 70 years. Rate control combined with antithrombotic therapies for NOAF is expected to contribute to further advances in treatment and improvement of survival.

Occurrence of deoxynivalenol and zearalenone in brewing barley grains from Brazil

Abstract

Barley (Hordeum vulgare L.) is an important cereal crop for food and represents one of the main ingredients in beer production. Considering the importance of barley and its derived products, the knowledge about the mycotoxin contamination in the barley production is essential in order to assess its safety. In this study, the levels of deoxynivalenol (DON) and zearalenone (ZEN) in brewing barley were determined using a LC-MS/MS method. A survey was conducted in 2015 to estimate the mycotoxin levels in these products (n = 76) from four crop regions in Brazil. The results showed high levels of DON and ZEN in the analyzed samples, with contamination levels of 94 and 73.6%, respectively. The mean levels of DON and ZEN ranged from 1700 to 7500 μg/kg and from 300 to 630 μg/kg, respectively. Barley samples from regions 1 and 2 presented higher levels of ZEN and DON, respectively, and those from region 4 presented lower levels of both. Co-occurrence of DON and ZEN was seen in the majority of the barley grain samples, and the mycotoxin content was above the maximum levels established by the Brazilian and European regulations.

Hodgkins Lymphoma presenting as an obstructing endobronchial mass--A rare presentation

We report a case of Hodgkin's lymphoma presenting as an endobronchial mass in a 40-year-old man with history of 8 months of non-specific symptoms like cough, fatigue and weight loss. Initially he was treated with broad-spectrum antibiotics for suspicion of pneumonia without recovery. Radiographic work-up showed cavitary consolidation of the upper lobe of the left lung, followed by bronchoscopy which showed obstructing mass of the upper lobe of the left lung mimicking primary lung carcinoma. Immunohistochemical staining of the specimen was suggestive of Hodgkin's lymphoma. The patient responded well to the chemotherapy regimen.

Acute glomerulonephritis secondary to Streptococcus anginosus

Streptococcus anginosus is a clinically important pathogen that is emerging globally but remains poorly investigated. Here, we report the first case of acute glomerulonephritis resulting from infection with S. anginosus. Glomerulonephritis is typically caused by S. pyogenes and reports secondary to other strains including S. zooepidemicus and S. constellatus exist. Infection with S. anginosus in this patient was associated with acute nephritis (haematuria, oedema and hypertension), nephrotic syndrome and progressive azotemia. There was activation of the complement system. The presence of low C1q and elevated anti-C1q binding complexes points to a potential pathogenic role. Testing for streptococcal antigens was strongly positive. Emerging nephritogenic strains of S. anginosus present a significant health concern for both developed and developing countries.

An Itch You Can’t Scratch: Researchers Find “Itch Receptors” in the Throats of Mice

Working with mice, Johns Hopkins researchers report they have found previously known skin itch receptors in the airways that appear to contribute to bronchoconstriction and airway hypersensitivity, hallmarks of asthma and other respiratory disorders. The investigators' experiments in mice suggest that the receptors' activation directly aggravates airway constriction and—if the same process is active in people—may be a promising new target for the development of drug therapies.

A novel subcutaneous site of islet transplantation superior to the liver

AbstractBackgroundIslet transplantation is an attractive treatment for patients with insulin-dependent diabetes mellitus, and currently the liver is the favored transplantation site. However, an alternative site is desirable because of the low efficiency of hepatic transplantation, requiring 2-3 donors for a single recipient, and because the transplanted islets cannot be accessed or retrieved.MethodsWe developed a novel procedure of islet transplantation to the inguinal subcutaneous white adipose tissue (ISWAT) of mice and described functional and morphological characteristics of transplanted syngeneic islets. Also, it was determined whether islet allograft rejection in the ISWAT can be prevented by immunosuppressive agents. Furthermore, it was examined whether human islets function when grafted in this particular site of immune-deficient mice.ResultsIn this site, transplanted islets are engrafted as clusters and function to reverse STZ-induced diabetes in mice. Importantly, transplanted islets can be visualized by CT and are easily retrievable, and allograft rejection is preventable by blockade of co-stimulatory signals. Of much importance, the efficiency of islet transplantation in this site is superior to the liver, in which hyperglycemia of diabetic recipient mice is ameliorated after transplantation of 200 syngeneic islets (the islet number yielded from 1 mouse pancreas) to the ISWAT but not to the liver. Furthermore, human islets transplanted in this particular site function to reverse diabetes in immune-deficient mice.ConclusionThus, the ISWAT is superior to the liver as the site of islet transplantation, which may lead to improved outcome of clinical islet transplantation.

Speech Perception Skills of Hindi Speaking Children with Pre-lingual Hearing Loss Using Hearing Aids and Cochlear Implants

Abstract

Very few published studies have reported auditory speech perception in Hindi children with pre-lingual hearing loss. The study is aimed at comparing the speech perception skills of Hindi speaking children with pre-lingual severe to profound hearing loss using hearing aids and cochlear implants. Forty-three 6 to 8-year old children were included as participants, of which 22 were bilateral behind-the-ear hearing aid (HA) users and 21 were unilateral cochlear implant (CI) users. Speech perception was assessed through a forced-choice, picture-pointing task using recorded stimuli presented at 70 dB HL in the sound field. The skills assessed include: (a) pattern perception, (b) bisyllabic word identification, (c) monosyllabic word identification, (d) sentence identification and (e) minimal pair identification. Children using CI consistently performed significantly better than those with HA on all tasks. For the skills assessed, best performance was seen in pattern perception and poorest performance was seen in monosyllabic word identification. One participant from the CI group obtained ceiling scores for pattern perception and bisyllabic word identification. There was no statistically significant difference in the performance of 6 to 7 and 7 to 8-year-old children for any of the tasks. Children fitted with CI have better access to the cues important for perception of speech and hence perform consistently better than those using hearing aids. Recorded speech perception test can be used with children using cochlear implants and hearing aids.
