ObjectivesThe aim was to investigate the relationship between groups of bacteria identified by cluster analysis of the DGGE fingerprints and the amounts and diversity of yeast present.MethodsBacterial and yeast populations in saliva samples from 24 adults were analysed using denaturing gradient gel electrophoresis (DGGE) of the bacteria present and by yeast culture.ResultsEubacterial DGGE banding patterns showed considerable variation between individuals. Seventy one different amplicon bands were detected, the band number per saliva sample ranged from 21 to 39 (mean±SD=29.3±4.9). Cluster and principal component analysis of the bacterial DGGE patterns yielded three major clusters containing 20 of the samples. Seventeen of the 24 (71%) saliva samples were yeast positive with concentrations up to 103cfu/mL. Candida albicans was the predominant species in saliva samples although six other yeast species, including Candida dubliniensis, Candida tropicalis, Candida krusei, Candida guilliermondii, Candida rugosa and Saccharomyces cerevisiae, were identified. The presence, concentration, and species of yeast in samples showed no clear relationship to the bacterial clusters.ConclusionDespite indications of in vitro bacteria-yeast interactions, there was a lack of association between the presence, identity and diversity of yeasts and the bacterial DGGE fingerprint clusters in saliva. This suggests significant ecological individual-specificity of these associations in highly complex in vivo oral biofilm systems under normal oral conditions.

Eosinophilic esophagitis (EoE) is an increasingly recognized eosinophilic gastrointestinal disorder that affects children and adults, with a prevalence of 5 per 10,000 inhabitants in Europe and the United States.1 Food antigens trigger more than 90% of cases; however, data suggest that aeroallergens may also play a pathogenic role.2,3 In addition, sublingual immunotherapy (SLIT) is being increasingly used for the treatment of allergic rhinitis and allergic asthma. In this report, we describe a 9-year-old enteral feeding tube–dependent boy who developed increased esophageal eosinophilia, suggesting EoE after initiating aeroallergen SLIT.

The global threat of increasing antibiotic resistance has driven regulatory organizations to advocate for the judicious and prudent use of antibiotics through robust antibiotic stewardship programs. Recently published antibiotic stewardship guidelines detail recommended strategies to optimize antibiotic use in a variety of health care settings.1 One such strategy includes a thorough penicillin allergy history assessment and, if indicated, subsequent penicillin skin testing in patients with a reported penicillin allergy.

Although the prognostic and predictive significance of human epidermal growth factor receptor 2 (HER2) in invasive breast cancer is well established, its role in ductal carcinoma in situ (DCIS) remains unclear. Reports on combined evaluation of both HER2 protein expression and HER2 amplification status in pure DCIS and DCIS adjacent to invasive ductal carcinoma (i.e., admixed DCIS) are scarce. In this study, immunohistochemistry and fluorescence in situ hybridization (FISH) were used to assess HER2 status in 72 cases of pure DCIS, 73 cases of DCIS admixed with invasive ductal carcinoma (IDC), and 60 cases of pure IDC. HER2 copy number-based amplification was present in 49% of pure DCIS, 16% of admixed DCIS, 18% of admixed IDC, and 8% of pure IDC. Amplified pure DCIS with clusters of HER2 signals showed a significantly lower HER2 copy number than amplified admixed DCIS with clusters. Whereas pure DCIS and admixed DCIS presented significant differences, the in situ and invasive component of admixed tumors showed striking similarities regarding mean HER2 and chromosome 17 centromere (CEP17) copy number, grade, and estrogen and progesterone receptor expression. The discrepant prevalence of HER2 amplification among breast cancer subgroups indirectly suggests that HER2 may not play a crucial role in the transition of in situ to invasive breast cancer. The similarities in HER2 amplification status between the in situ and invasive component of admixed tumors hint at a common biological pathway for both components. Our data support the theory that pure DCIS, pure IDC, and admixed lesions have a common progenitor, but can progress as separate lineages.

The patient is a 61-year-old white female with a 2-year history of painful and pruritic rash that began on the neck and progressed to involve the face, eyelids, scalp, neck, chest, back, bilateral upper extremities, axillae, popliteal fossae, and the groin. The patient has multiple family members with the same condition. Examination of the skin revealed erythematous macerated eroded plaques involving over 60% BSA. No mucosal or nail changes were identified. The patient had failed multiple therapies including topical and oral steroids, acitretin, dapsone, and valacyclovir.

Hailey–Hailey disease, or familial benign pemphigus, is a chronic, autosomal dominant or rarely sporadic condition characterized by painful erosions and macerations in the skin folds. Classically, treatment options for this condition include topical steroids, topical and systemic retinoids, and immunomodulators such as methotrexate. Although low-dose naltrexone (LDN) has never been reported in the literature as a treatment for Hailey–Hailey, patients on online blogs, websites, and Facebook support groups have attested to the success of this relatively benign medication in the treatment of their disease.

Acne vulgaris is a chronic inflammatory disease of the pilosebaceous units (PSU). Light therapy has attracted medical interest as a safe, alternative treatment for acne. Both blue and red light therapies at high doses >10 J/cm2 have demonstrated marked effects on inflammatory acne lesions. However, few studies have investigated the effects of lower doses of light. In this study, the biological effects of low red light doses were investigated using an in vitro model previously developed to mimic the inflammation, and hyperkeratinization seen clinically in acne.

Background: Morphea en coup de sabre (ECDS), which literally means "blow from a sword," is a type of linear morphea affecting the frontoparietal scalp and/or the paramedian forehead. Neurologic findings are common with ECDS, most common being complex partial seizures and headaches. Brain involvement evident on neuroimaging can be seen both in symptomatic and asymptomatic patients. Here we present a rare case of ECDS and epilepsy with MRI findings of ipsilateral porencephalic brain cyst.

Background: Procedural dermatology, including Mohs micrographic surgery (MMS), hair transplantation (HT), and cosmetic surgery can induce significant patient anxiety. While pre-procedural anxiolysis has been documented in other fields, there is only one study published for its usage in procedural dermatology and MMS. Herein, we perform a systematic literature review and discuss our center's experience with pre-procedural anxiolytics (PPA) in MMS and HT.

Background: Pigmented purpuric dermatosis (PPD), or capillaritis, is an inflammatory skin disorder of unclear etiology most classically presenting as petechiae and red-brown macules on the lower extremities. PPD is characterized histologically by perivascular lymphocytes with extravasation of erythrocytes and hemosiderin deposition. PPD includes multiple subtypes including Schamberg's disease, Purpura annularis telangiectoides of Majocchi, pigmented purpuric lichenoid dermatitis of Gougerot and Blum, eczematid-like purpura of Doucas and Kapetanakis and Lichen aureus, as well as the newly described granulomatous PPD.

Antimicrobial peptides (AMPs) form a part of the skin's innate immune system. Their primary activity is to provide antimicrobial benefits and hence protect from infections. During the course of an infection or an injury, these AMPs become activated and provide protection against pathogens. Major AMPs that are present constitutively on human skin include psoriasin, RNAse7, and lysozyme while other AMPs like LL-37, HBD2, and HBD3 are induced after infection, injury or inflammation. Niacinamide is a well-known cosmetic ingredient that has been used traditionally for skin lightening, antiaging and skin barrier building benefits.

Background: Dermatophyte infections involving the skin, hair, or nails affect an estimated 25% of the world's population, and accounted for 51 million outpatient visits over a 10-year period (1995-2004) in the United States alone. Dermatomycosis is routinely managed by dermatologists, though given the diversity of clinical presentations, is sometimes misdiagnosed, which can result in inappropriate therapy, worsening of symptoms, and even result in additional skin and soft tissue infections.

Nasal reconstruction in the setting of rhinophyma poses some unique challenges. Traditional options for nasal ala reconstruction, such as bilobed flaps, nasolabial transposition flaps, and skin grafts, are often unable to provide an adequate tissue match for rhinophymatous skin. Second intention healing is a viable option for small defects on concave surfaces, but there is a risk of alar notching at the free margin. We present a unique technique for reconstruction of a 1.4 cm nasal ala defect with concomitant moderate rhinophyma after Mohs micrographic surgery.

Background: Hidradenitis suppurativa (HS), a component of the follicular occlusion triad, is a chronic inflammatory condition of the terminal hair follicle that has a predilection for the apocrine gland–bearing areas, including the axillary, inguinal, and anogenital regions. An infectious component has been suspected in the condition, but it is challenging to prove a pathologic component as bacteria can grow without presence of infection. "Kissing lesions" are lesions that appear on opposing surfaces that come into contact, and they typically signify transfer of an infectious agent such as sexually transmitted infections, including chancres seen in primary syphilis.

CD30 -positive lymphoproliferative skin diseases are the second most common form of cutaneous T cell lymphoma and have an excellent prognosis. We present a case of a primary cutaneous anaplastic large cell lymphoma. A 76-year-old man presented with an asymptomatic and recurring lesion on the anterior aspect of the left arm and forearm. On examination, confluent, infiltrated erythematous papules with superficial lichenification were seen. Histologic examination showed extensive lichenoid infiltrate without epidermotropism and immunohistochemical study showed great amount (more than 75%) of CD30+ lymphocytes confirming the diagnosis of primary cutaneous anaplastic large cell lymphoma (PCALCL).

Pancreatic panniculitis is a rare inflammatory disease affecting the subcutis in a small percentage of patients with pancreatic disease, postulated to be due to enzymatic degradation of adipose tissue by pancreatic lipase and amylase. Elevated serum lipase and amylase levels can occur in patients with diabetic ketoacidosis (DKA), even without evidence of pancreatitis. We report a case of a newly diagnosed diabetes mellitus patient presenting with DKA and subsequent pancreatic panniculitis lesions over her lower limbs, but without evidence of pancreatitis.

Background: Despite achievement of elimination status of leprosy in India in 2000, it continues to harbour more than two-thirds of the world's leprosy population. Certain states and union territories continue to report high prevalence of the disease. The current study provides an insight into the current disease trends in a tertiary care hospital in New Delhi, India.

We have reported previously that women whose facial skin appears exceptionally youthful have distinct patterns of epidermal gene expression as compared to women who appear average or older than their actual chronological age. The majority of these epidermal genes (80%) showed a strong negative age-dependency in older-appearing women; by cluster analysis these could be categorized into 20 expression patterns capturing distinct biological pathways. In the current work we used a combined in vitro and in silico approach to determine the extent to which combinations of materials may affect expression of these genes.

Striae distensae, or stretch marks, is a common condition associated with continuous and progressive stretching of the skin, such as with rapid weight gain, puberty, or pregnancy. Typically, these lesions involve the abdomen, breasts, or hips. Striae distensae initially appear as raised pink or purple linear streaks that run perpendicular to the direction of skin tension. Over time, these streaks mature into hypopigmented, depressed, and finely wrinkled scar-like bands. Although stretch marks are not physically dangerous, their appearance is often distressful to individuals.

Introduction and Objectives: Ingenol disoxate (IngDsx, LEO 43204) is a novel ingenol derivative selected based on improved thermostability and biologic properties over those of ingenol mebutate (IngMeb). Previous studies demonstrated satisfaction and cosmetic improvements in patients treated with IngMeb. As part of a phase 2 trial, we investigated these outcomes for field treatment with IngDsx in patients with actinic keratoses (AK) on face/chest (F/C) and scalp (S) (NCT02305888).

A 75-year-old woman presented with 2-year history of persistent pruritic dermatitis on her trunk. She had been treated by topical corticosteroids without improvement. Around the same time, she felt numbness on her face, and became unsteady on her feet. She also had appetite loss and sick feelings, with 5-kg weight loss in 9 months. As there were no abnormal findings with endoscopy and blood tests, she had been treated as dysautonomia. According to her family, she seems to have personality change.

During epithelial-to-mesenchymal transition, cancer cells lose adhesion capacity gaining migratory properties. The role of the process on prognosis has been evaluated in 50 cases of laryngeal carcinoma.
E-cadherin, N-cadherin, β-catenin, α-catenin, γ-catenin, caveolin-1, and vimentin immunohistochemical expression were evaluated using a double score based on staining intensity and cellular localization.
Cytoplasmic E-cadherin and α/γ catenin staining were associated with a decrease in survival, cytoplasmic β-catenin was associated with advanced stage, and N-cadherin and vimentin expression were associated with poor differentiation and tumor relapse. On the basis of cancer cells, epithelial or mesenchymal morphological and immunophenotypic similarity we identified 4 main subgroups correlated with a transition to a more undifferentiated phenotype, which have a different pattern of relapse and survival.
The negative prognostic role of epithelial-to-mesenchymal transition has been confirmed and a predictive role in glottic tumors has been suggested, leading us to propose epithelial-to-mesenchymal transition as an additional adverse feature in laryngeal carcinoma.
Oncologic outcomes for induction chemotherapy and its role in patients with advanced olfactory neuroblastoma (ONB) remain unclear.
A retrospective review of 15 consecutive patients with extensive local invasion and/or nodal disease treated with induction chemotherapy with curative intent followed by definitive local therapy.
The majority of patients were treated with cisplatin and etoposide. The response to chemotherapy was 68% (10/15). Response was 78% (7/9) in the high Hyams high-grade group and 50% (3/6) in the Hyams low-grade group. Seven patients had complete response (CR) and 3 patients were able to avoid orbital exenteration. The 5-year disease-free survival (DFS) and overall survival (OS) were 71% and 78%, respectively, with a trend toward improved survival in patients with CR.
ONB is a chemosensitive tumor and induction chemotherapy is an acceptable strategy for aggressive and locoregional advanced disease. Hyams grade may predict chemosensitivity and CR may be associated with improved survival.
Sinonasal undifferentiated carcinoma (SNUC) is a rare aggressive disease arising in the nasal cavity and paranasal sinuses with poor prognosis and unclear optimal management.
Forty patients were analyzed. Nasal cavity was the most common primary site. Most patients presented with T4 disease, received trimodality therapy, and were treated with intensity-modulated radiotherapy (IMRT).
Median follow-up was 6.9 years. Sixteen patients (40%) experienced recurrent disease, 5 local (12.5%), 1 regional (2.5%), and 10 distant (25%). The 5-year overall survival (OS), recurrence-free survival (RFS), and locoreginal control (LRC) were 44%, 39%, and 71%, respectively. Patients treated with trimodality therapy had better outcomes compared to single modality therapy. Improved OS was noted with IMRT and with doses ≥60 Gy. The most common cause of death was distant metastasis.
SNUC is an aggressive malignancy with a high tendency to metastasize. Better outcomes were obtained with a trimodality approach. Modern radiotherapy (RT) techniques and doses ≥ 60 Gy were associated with improved OS.
Practice variability exists for the extent of neck dissection undertaken for papillary thyroid carcinoma (PTC) metastatic to the lateral neck nodes, with disagreement over routine level V dissection.
We performed a retrospective medical record review of PTC patients with lateral neck nodal metastases treated at University Health Network from 2000 to 2012. Predictive factors for regional neck recurrence, including extent of initial neck dissection, were analyzed using Cox regression.
Out of 204 neck dissections in 178 patients, 110 (54%) underwent selective and 94 (46%) had comprehensive dissection including level Vb. Mean follow-up was 6.3 years (SD). Significant predictors of regional failure were the total number of suspicious nodes on preoperative imaging (p = 0.029), largest positive node on initial neck dissection (p < 0.01), and whether patients received adjuvant radiotherapy (p = 0.028). The 5-year ipsilateral regional recurrence rate was 8 and 9% with selective and comprehensive dissection, respectively (p = 0.89).
The extent of neck dissection did not predict the probability of regional recurrence in PTC patients presenting with lateral neck metastases.
More than 40 years ago, Kimura et al. discovered that basophils are enriched in sputum samples of asthma patients (1). Since then, various scientific approaches have attempted to elucidate the role of basophils in the pathophysiology of asthma. The scarcity of basophils and technical limitations of earlier studies have made it difficult to increase our understanding how basophils affect the disease course in asthma.

Allergy immunotherapy (AIT) is the only treatment for allergic rhinitis (AR) and/or allergic asthma (AA) with long-term efficacy. However, there are few real-life data on the progression of AR and/or AA in patients receiving AIT.
To assess the real-world, long-term efficacy of grass-pollen sublingual immunotherapy (SLIT) tablets in AR and their impact on asthma onset and progression.
In a retrospective analysis of a German longitudinal prescription database, AR patients treated with grass pollen SLIT tablets were compared with a control group not having received AIT. Multiple regression was used to compare changes over time in rescue symptomatic AR medication use after treatment cessation, asthma medication use, and the time to asthma onset in the two groups.
After applying all selection criteria, 2851 SLIT and 71275 Control patients were selected for the study.After treatment cessation, AR medication use was 18.8 percentage points lower (after adjustment for covariates, and relative to the pre-treatment period) in SLIT tablet group than in the non AIT group (p<0.001). Asthma onset was less frequent in SLIT tablet group than in non AIT group (odds ratio: 0.696, p=0.002), and time to asthma was significantly longer (hazard ratio: 0.523; p=0.003). After SLIT cessation, asthma medication use fell by an additional 16.7 percentage points (relative to the pre-treatment period) in the SLIT tablet group vs. the non AIT group (p=0.004).
Real-world treatment of AR patients with grass pollen SLIT tablets was associated with slower AR progression, less frequent asthma onset and slower asthma progression

Bibliometrics uses analysis of content and citations of journal articles to quantify trends in published data. We aim to use bibliometric analysis to identify the global contribution by country to the ENT surgical literature over a five-year period.
The top 20 countries for number of articles published in surgery and the 11 English Language Otolaryngology surgical journals with the highest impact factors (IF) were included. Numbers of scientific articles per year (2009-2013) per country for each journal were identified through PubMed. As a marker of quality, a mean IF for each country was calculated, using number of articles and journal IF. This data was compared against population, GDP and dollars spent on research.
In total, 10,574 articles were included. The USA was the largest contributor, with 4462 articles published over 5 years. The second largest was the UK (1215 articles). Spain's mean IF was 2.136, followed by Taiwan (2.110). The Netherlands (19.7) and the UK (18.9) had the highest number of publications per million population (PMP). When considering overall research spending per country, Greece had the most cost-effective publication output. The least cost-effective country was Japan. India, Greece and Japan had the greatest increase in publication quality.
Bibliometric analysis can be used to identify not only major centres of English language ENT surgical research, such as the USA and UK but centres that are producing high-quality data, such as Spain, and cost-effective research, such as the UK. It can also highlight areas of increasing success in ENT research.

Wir berichten über den atypischen klinischen Verlauf eines Patienten mit einem seltenen apokrinen Schweißdrüsenkarzinom, bereits initial vorliegender lymphogener Metastasierung und einer metachronen solitären Fernmetastase mit einer jetzt erreichten Überlebenszeit von mehr als 4 Jahren und verbinden die Falldarstellung mit einer aktuellen Literaturübersicht. Es gibt nur eine sehr kleine Zahl von Patienten mit dieser Tumorentität. Die Empfehlungen zur Diagnostik und Therapie sind nicht durch prospektiv randomisierte Studien abgesichert und beruhen sowohl auf Einzelfallberichten als auch auf neuen immunhistochemischen und genetischen Markerprofilen.
Selektivverträge gewinnen in der Versorgungsgestaltung immer mehr an Bedeutung. Bis heute existieren keine konsentierten Standardempfehlungen zu ihrer Evaluation.
Vor diesem Hintergrund wurde durch die bundesweite Konsensuskonferenz zur Versorgung von Menschen mit chronischen Wunden eine Empfehlung zur Evaluation von Selektivverträgen bei Patienten mit einem Ulcus cruris (UC) entwickelt und konsentiert.
Auf der Basis einer systematischen Literaturrecherche mit anschließender Handrecherche über weitere mögliche Evaluationsindikatoren in der Versorgung von Patienten mit einem UC wurde ein Delphi-gestützter Konsensusprozess durch wissenschaftliche Fachgesellschaften, Berufsverbände, Krankenkassen und Versorgungsnetze durchgeführt.
Zur Bewertung von Wirtschaftlichkeit und Qualität der Versorgung wurde in 6 moderierten Präsenzsitzungen und 5 mehrstufigen Online-Umfragen eine Empfehlung zur Evaluation von Selektivverträgen bei Patienten mit einem UC konsentiert. Insgesamt n = 44 Evaluationsindikatoren wurden in die Teilbereiche Struktur‑, Prozess- und Ergebnisqualität untergliedert. Die Ergebnisqualität wurde zudem weiter in die Bereiche klinische, patientenberichtete und kostenbezogene Indikatoren unterteilt.
Die entwickelten und konsentierten Evaluationsindikatoren bilden die Versorgungsqualität bei Patienten mit einem UC ab und können individuell eingesetzt werden, je nach vereinbarten vertragsspezifischen Versorgungszielen. Nach bundesweiter Implementierung dieses Standards wird die Vergleichbarkeit von Selektivverträgen bei Patienten mit einem UC gewährleistet und verstetigt.
Der behaarte Kopf kann durch vielfältige Erkrankungen in ebenso vielfältiger Weise betroffen werden. Neben Rötung und Schuppung findet sich häufig quälender Juckreiz, der zu massiven Beeinträchtigungen der Patienten führt. Die Kopfpsoriasis und das seborrhoische Kopfekzem gehören zu den häufigsten Erkrankungen, die im klassischen Fall einfach zu unterscheiden sind, aber auch Überschneidungen und klinische Ähnlichkeiten zeigen können. Die scharf begrenzten, die Stirn-Haar-Grenze überschreitenden erythematosquamösen Plaques der Psoriasis stehen eher unscharf begrenzten, düsterroten Erythemen mit einer gelblich-fettigen Schuppung des seborrhoischen Ekzems gegenüber. Bei Letzterem findet sich häufig eine diffuse Alopezie, während Haarausfall bei der Psoriasis eher selten ist, aber auch als unerwünschte Wirkung verschiedener Therapeutika auftreten kann. Die Behandlung richtet sich nach Akuität und Ausdehnung der Erkrankung wie auch Einschränkung der Betroffenen. Sie ist zunächst topisch unter Einsatz von Kortikosteroiden, bei der Psoriasis auch von Vitamin-D-Derivaten, beim seborrhoischen Ekzem von topischen Antimykotika. In schweren Fällen unter Beteiligung des übrigen Integuments bedarf insbesondere die Psoriasis einer systemischen Therapie mit den klassischen Wirkstoffen Methotrexat, Fumaraten oder Ciclosporin bis zu den Biologika, die Tumornekrosefaktor-α, Interleukin-12/23 oder Interleukin-17 hemmen. Eine Systemtherapie des seborrhoischen Ekzems ist nur selten nötig und kann mit Kortikosteroiden, Antimykotika oder Vitamin-A-Derivaten erfolgen. Wichtig ist eine intensive Beratung der Patienten über die Notwendigkeit einer konsequenten und lang währenden Anwendung der Therapeutika sowie zur Anwendung von hautschonenden Pflegeprodukten und Maßnahmen.
Die Palisadengranulome umfassen eine Gruppe verschiedener Erkrankungen mit gleichartigem histomorphologischem Bild der Granulombildung in der Haut. Histologisch kennzeichnend sind dermal und subkutan lokalisierte Herde mit verschiedenartig degeneriertem Bindegewebe, die von einem palisadenartig angeordneten Infiltrat aus Histiozyten und Riesenzellen umgeben sind (nekrobiotisches Granulom). Im Zentrum finden sich Ablagerungen von Muzin und Fibrin. Die beiden klassischen Hauterkrankungen, die histologisch ein Palisadengranulom ausbilden, sind das Granuloma anulare und die Necrobiosis lipoidica. Daneben können palisadenartig angeordnete Granulome in der Haut auch im Rahmen von Systemerkrankungen auftreten wie bei Rheumaknoten und nekrobiotischem Xanthogranulom. Über die Ätiopathogenese der Erkrankungen ist wenig bekannt. Klinisch präsentieren sie sich variabel. Therapeutisch sind sie häufig schwer zu beeinflussen.
Chronic facial paralysis induces degenerative facial muscle changes on the involved side, thus, making the individual seem as older than their actual age. Furthermore, contralateral facial hypertrophy aggravates facial asymmetry. A thread-lifting procedure has been used widely for correction of a drooping or wrinkled face due to the aging process. In addition, botulinum toxin injection can be used to reduce facial hypertrophy. The aim of study was to evaluate the effectiveness of thread lifting with botulinum toxin injection for chronic facial paralysis.
A total 34 of patients with chronic facial paralysis were enrolled from March to October 2014. Thread lifting for elevating loose facial muscles on the ipsilateral side and botulinum toxin A for controlling the facial muscle hypertrophy on the contralateral side were conducted. Facial function was evaluated using the Sunnybrook grading system and dynamic facial asymmetry ratios 1 year after treatment.
All 34 patients displayed improved facial symmetry and showed improvement in Sunnybrook scores (37.4 vs. 83.3) and dynamic facial asymmetry ratios (0.58 vs 0.92). Of the 34 patients, 28 (82.4%) reported being satisfied with treatment.
The application of subdermal suspension with a reabsorbable thread in conjunction with botulinum toxin A to optimize facial rejuvenation of the contralateral side constitutes an effective and safe procedure for face lifting and rejuvenation of a drooping face as a result of long-lasting facial paralysis.
This article presents a case of malignant transformation of vestibular schwannoma 13 years after stereotactic radiation therapy, which lead to an acute life-threatening condition. Although the observation is currently only based on case reports, an increasing number of these support the hypothesis that there is a relevant risk of malignant transformation in the long-term course of previously irradiated vestibular schwannomas. Therefore, long-term MRI follow-up should be considered.
Recessive mutations in the LAMA3A, LAMB3 and LAMC2 genes coding for laminin-332 (α3aβ3γ2) chains cause different junctional epidermolysis bullosa (JEB) subtypes. Biallelic truncating mutations in any of the three genes usually lead to lack of protein expression resulting in the severe generalized JEB subtype, while missense or splicing mutations in at least one allele lead to reduced expression typical of generalized intermediate or localized JEB. Here, we molecularly characterized an adult JEB patient showing negative skin staining for the anti-β3 chain mAb K140. This antibody recognizes an as yet unidentified epitope within the β3 short arm. The patient harbours a homozygous splicing mutation resulting in major aberrant transcripts with partial skipping of the LAMB3 exon coding for the laminin EGF-like (LE) motif 2 of the β3 short arm (β3-LE2). At protein level, mutation consequences predict a misfolded β3-LE2 motif and, indeed, we found that laminin-332 is correctly assembled but retained in the endoplasmic reticulum (ER) where it co-localizes with the lumenal ER chaperone BiP, leading to dramatically reduced secretion. Lack of K140 reactivity to mutant laminin-332 was confirmed by immunoprecipitation and Western blot analyses. Our findings identify the β3-LE2 subdomain as the region recognized by K140 mAb. In addition, they further show that misfolding of laminin-332 structural motifs and subsequent ER protein retention is a common pathomechanism in JEB generalized intermediate. In addition to be useful for antigen mapping diagnosis of JEB subtypes, this knowledge is relevant to the design of therapeutic strategies aimed at releasing ER-retained laminin-332 in JEB.

In the current work, we present our new guideline for the diagnosis and treatment of scabies which we, the Executive Committee convened by the Japanese Dermatological Association, developed to ensure proper diagnosis and treatment of scabies in Japan. Approval of phenothrin topical use under the National Health Insurance in August 2014 led to this action. Permethrin, a topical anti-scabietic medication belonging to the same pyrethroid group as phenothrin, is already in use worldwide. In this guideline, we introduce criteria for a proper diagnosis of scabies, treatment algorithm for common and crusted (hyperkeratotic) scabies, and prevention. The major change from our second edition is the treatment algorithm. As phenothrin is now available, the first-line therapy for common scabies is either topical phenothrin lotion or oral ivermectin. The second-line option for topical treatment is sulfur-containing ointments, crotamiton cream or benzyl benzoate lotion. γ-Benzene hexachloride ointment is no longer provided for clinical use. In an immunosuppressed patient, the treatment option is still the same, but with close follow up. If the symptoms persist, diagnosis and treatment must be reassessed. For hyperkeratotic scabies and nail scabies, removal of thick crust, cutting of nails and occlusive dressing are additionally required. The safety and effectiveness of combined treatment with topical and oral medications are not yet confirmed. Further assessment is needed. In addition to appropriate treatment, it is essential to educate patients and health-care workers and to conduct epidemiological studies to prevent further spread of the disease through effectively utilizing available resources including manpower, finance, logistics and time.
To assess the effect of truncal ligation of the inferior thyroid artery in comparison with ligation of secondary branches as a risk factor for postoperative hypocalcemia.
A search was conducted using the Medical Subject Headings and free-text terms "thyroid*" and "truncal ligation*" in PubMed Central, PubMed, Embase, and Latin American and Caribbean Health Sciences Literature databases for trials published between January 1985 and October 2016. A Google search with the same terms, and a "snowball" approach was designed to retrieve the largest number of articles.
Controlled trials (randomized or not) of adults who underwent total/bilateral subtotal thyroidectomy were searched, and truncal ligation versus nontruncal ligation of the inferior thyroid artery was compared. Data were acquired following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Methodological quality of randomized controlled trials was assessed in accordance with Cochrane Collaboration guidelines, and for nonrandomized controlled trials, the Newcastle-Ottawa quality assessment scale for cohort studies was used. Pooled results are presented as risk differences with a random effects model. The main outcome was postoperative temporary and definitive hypocalcemia.
We found 11 nonrandomized controlled trials and nine randomized controlled trials with 1940 patients: 977 patients in the trunk ligation group and 963 patients in the nontruncal ligation group. The risk difference for biochemical hypocalcemia was 6% (95% confidence interval [CI]: 2% to 11%), for symptomatic hypocalcemia 6% (95% CI: 1% to 10%), and definitive hypocalcemia 0% (95% CI: −1% to 1%) in the whole group.
Truncal ligation of the inferior thyroid artery increases the risk of temporary and symptomatic hypocalcemia but not the risk of definitive hypocalcemia. Laryngoscope, 2017
This study systematically reviews the existing literature on the efficacy of adjuvant corticosteroids in improving clinical outcomes after peritonsillar abscess (PTA) drainage.
Systematic review.
We performed a literature search of MEDLINE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Scopus, Embase, and ClinicalTrials.gov from inception to June 2016. Inclusion criteria included randomized controlled trials (RCTs) evaluating adjuvant corticosteroids after PTA drainage. Data were systematically collected on study design, patient demographics, and clinical characteristics. Two independent investigators reviewed all manuscripts and summarized the data.
Three RCTs comprising 153 patients were included. The results were not pooled due to heterogeneity in the method in which outcomes were measured and reported. The trials also varied on the type of steroid (dexamethasone, methylprednisolone) administered and method of drainage (incision, aspiration). All three RCTs reported statistically significant improvement in body temperature from adjuvant steroid administration compared to placebo. Pain scores, mouth opening, time to painless oral intake, and duration of hospitalization were significantly improved in only one or two of the three RCTs between the steroid and control group. No adverse side effects from steroid administration were reported.
Steroids as an adjunct therapy to the treatment of PTA may result in faster recovery. However, further investigation with larger RCTs and standardized outcomes are warranted.

We describe the case of a 34-year-old patient presenting with the unique combination of bilateral vestibulopathy in combination with noise- and pressure-induced nystagmus. Bilateral vestibular dysfunction was demonstrated by pathological results in video-based head impulse testing as well as in caloric testing. In contrast, cervical vestibular-evoked myogenic potentials were normal, demonstrating normal sacculus function. Due to the positive Tullio phenomenon, semicircular dehiscence syndrome was excluded. Recently, this symptom combination was related to the histopathological finding of vestibular atelectasis.

The objective of this study was to evaluate the impact of developing an integrated head and neck cancer speech and swallowing rehabilitation program on physician/team focus on functional outcomes.
Prospective cross-sectional design.
Surveys regarding physician behavior and patient satisfaction with speech and swallowing were administered in an academic oncology practice prior to and 1 year following establishment of a dedicated head and neck speech and swallowing rehabilitation program. Participants included new and established head and neck cancer patients recruited consecutively. The primary outcome was physician behavior regarding speech and swallowing outcomes (as measured by discussion of function, providing suggestions regarding function, and referral to speech-language pathology services).
A total of 199 surveys were returned at the first time point and 271 at the second. Demographic variables were comparable between the two groups. The later cohort was more likely to report team discussion and suggestions regarding speech and swallowing function than the former (P < .001, 95% confidence interval [CI]: −0.775 to −0.265; P < .001, 95% CI: −0.928 to −0.035, respectively). Although there was no significant difference between the groups in regard to satisfaction with speech (P = .07), more favorable satisfaction with swallowing was reported by the later cohort (P = .028, 95% CI: −0.531 to −0.029).
Integration of speech and swallowing rehabilitation into head and neck cancer programs is associated with increased physician focus on functional outcomes and greater patient satisfaction in regard to swallowing function. We advocate for standard integration of such services into the multidisciplinary head and neck cancer care team.

Upper airway stimulation (UAS) of the hypoglossal nerve has been implemented in the routine clinical practice for patients with moderate-to-severe obstructive sleep apnea (OSA) who could not adhere to continuous positive airway pressure. This study reports objective and patient-reported outcome after 12 months of implantation.
Multicenter prospective single-arm study.
Consecutive patients who received the UAS system (Inspire Medical Systems, Inc., Minneapolis, Minnesota, Maple Grove, MN, U.S.A.) were enrolled in three German centers. Key study exclusion criteria included body mass index > 35 kg/m2, apnea–hypopnea index (AHI) < 15 or > 65, or complete concentric collapse at the soft palate during sedated endoscopy. Data collection at 6- and 12-month visit include home sleep test and patient-reported outcome measures.
Among the total of 60 participants, the median AHI reduced from 28.6 to 9.5 from baseline to 12 months. Patient-reported outcome measured in Epworth Sleepiness Scale and Functional Outcomes of Sleep Questionnaire both improved significantly from baseline to 12 months. The average usage time was 39.1 ± 14.9 hours per week among all participants based on recordings by the implanted device. One patient requested a removal of the device for cosmetic and other personal reasons and was completed without sequelae.
This study supported that UAS is a safe and effective treatment option for patients with OSA in routine clinical practice.

Poor nutritional status in patients with head and neck squamous cell carcinoma (HNSCC) is associated with tumor progression and survival. This study examined the prognostic value of nutritional and hematological markers in patients with HNSCC who received definitive treatments.
A prospective observational cohort study.
This study included 338 consecutive patients who underwent surgery and/or radiotherapy/chemoradiotherapy for treatment-naïve HNSCC. Body weight and nutritional and hematological parameters were regularly measured before and after treatment. Univariate and multivariate analyses using Cox proportional hazards models were performed to identify factors associated with disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS).
Body weight, serum total protein and albumin levels, and hematological variables significantly decreased after treatment. Univariate analyses illustrated that age, tumor site, T and N classifications, overall stage, pretreatment serum albumin (<3.5 g/dL) and hemoglobin (<12 g/dL) levels, and neutrophil-lymphocyte ratio were significantly associated with DFS, CSS, and OS (all P < .05). Multivariate analyses identified age, tumor site, N classification, and pretreatment albumin levels as independent predictors of DFS, CSS, and OS (all P < .05). Patients with low serum albumin levels prior to treatment experienced approximately sixfold increases in the risks of tumor progression and cancer-specific and overall mortality compared to the findings in their counterparts.
Our results suggest that pretreatment serum albumin levels predict DFS, CSS, and OS in patients who received definitive treatment for HNSCC. These findings might help to predict treatment outcome and guide nutritional intervention in patients with HNSCC.

First, to determine if prosthesis length plays a role in optimizing successful hearing outcomes in stapedotomy surgery; and second, to determine if patient factors such as height are correlated with prosthesis length.
Retrospective chart review.
Retrospective chart review of patients undergoing stapedotomy surgeries with adequate follow up. Length of prosthesis, pre-/postoperative audiograms, and follow-up data were obtained.
The primary group consisted of 227 cases. The prosthesis length ranged from 3.75 mm to 4.75 mm (median 4.25 mm). The greatest improvement in postoperative air–bone gap (ABG) occurred in the 4.25 mm group, and the least in the 3.75 mm group. Patient height showed a positive, although weak, correlation with prosthesis length. No findings reached statistical significance.
Accurate measurement of prosthesis length is important for successful postoperative hearing outcomes. There is a positive but not significant correlation between patient height and prosthesis length.

Bone wax is an effective hemostatic agent that generally is considered safe. However, because it is nonabsorbable, significant complications can occur. We present the first two reported cases of delayed migration and extrusion of bone wax through postauricular wounds due to foreign body reaction and granuloma formation following mastoid surgery. We also present a literature review of complications associated with intraoperative bone wax use and discuss alternative hemostatic agents. Laryngoscope, 2017
Delineate factors impacting the creation and use of patient-derived xenografts (PDXs) of human papilloma virus-related (HPV+) head and neck squamous cell carcinomas (HNSCCs).
Laboratory-based translational study.
Fifty-one surgically resected HNSCCs, including 31 HPV + cancers, were implanted into NOD/SCID/IL-2Rγ-/- (NSG) mice using standardized methodology. Clinical and pathologic factors were tested for association with engraftment. The gross, histologic, and molecular features of established HPV + PDXs were analyzed in comparison to their tumors of origin.
Negative HPV status and perineural invasion (PNI) were independent, additive factors associated with increased PDX formation. Epstein-Barr virus–positive (EBV+) human large B-cell lymphomas grew from 32% of HPV + HNSCC cases that failed to engraft. Successfully established HPV + PDXs retained basaloid histology and often developed cystic growth patterns typical of HPV + nodal metastases. They also maintained elevated p16INK4A levels and expression of E6/E7 viral oncogene transcripts.
Reduced engraftment by HPV + tumors lacking PNI likely results in selection biases in HNSCC PDX models. Formation of EBV + lymphomas in NSG mice further reduces the generation of HPV + models and must be ruled out before long-term use of PDXs. Nevertheless, the retention of distinctive pathologic traits and viral oncogene expression by HPV + PDXs provides a viable in vivo platform for basic and translational studies as well as a resource for generating advanced in vitro models.

A systematic review and meta-analysis of the literature was undertaken, examining the association between tobacco smoking and olfactory function in humans, utilizing PubMed and Web of Science (1970–2015) as data sources.
Systematic literature review and meta-analysis.
This database review of studies of smoking and olfaction, with a focus on identifying high-quality studies (based on modified versions of the Newcastle-Ottawa Scale), used validated olfactory tests among the generally healthy population.
We identified 11 studies meeting inclusion criteria. Of 10 cross-sectional studies, two were excluded from meta-analysis because the cohorts they studied were included in another article in the review. In meta-analysis, current smokers had substantially higher odds of olfactory dysfunction compared to never smokers (odds ratio [OR] = 1.59, 95% confidence interval [CI] = 1.37–1.85). In contrast, former smokers were found to have no difference in risk of impaired olfaction compared to never smokers (OR = 1.05, 95% CI = 0.91–1.21). The single longitudinal study reviewed found a trend toward increased risk of olfactory decline over time in ever smokers; this trend was stronger in current as compared to former smokers.
Current smoking, but not former smoking, is associated with significantly increased risk of olfactory dysfunction, suggesting that the effects of smoking on olfaction may be reversible. Future studies that prospectively evaluate the impact of smoking cessation on improvement in olfactory function are warranted.

Das Ösophaguskarzinom ist in Deutschland eher selten, die Häufigkeit von Tumoren des distalen Ösophagus und des gastroösophagealen Übergangs nimmt jedoch zu. Aufgrund des oft fortgeschrittenen Tumorstadiums bei der Diagnosestellung ist diese Entität ein Paradebeispiel für die Notwendigkeit einer optimalen interdisziplinären Zusammenarbeit von Chirurgie, Strahlentherapie und Onkologie. Beim Plattenepithelkarzinom ist ab einem Stadium cT3 eine präoperative Radiochemotherapie indiziert. Bei Plattenepithelkarzinomen im oberen Drittel des Ösophagus stellt die definitive Radiochemotherapie ohne Operation oft die bevorzugte Option dar. Bei Adenokarzinomen ab einem Stadium cT3 sollen entweder eine präoperative Radiochemotherapie oder eine perioperative Chemotherapie durchgeführt werden, da dadurch das Überleben im Vergleich zur alleinigen Operation verbessert wird. Eine Induktionschemotherapie vor Radiochemotherapie ist vielversprechend, jedoch außerhalb von Studien noch nicht belegt.
The authors report the successful repair of a Crawford type III thoracoabdominal aortic aneurysm (TAAA) with a thrombosed infrarenal component using a modified hybrid technique without aortic clamping in a high-risk patient. A 64-year-old male with a history of hypertension, diabetes, and severe chronic obstructive pulmonary disease presented with acute on chronic backache and bilateral short distance claudication. A computerized tomography scan demonstrated a large, nonleaking Crawford type III TAAA with thrombosed infrarenal component of the aneurysm. In addition, both common iliac arteries were occluded with the chronic thrombus. A single-stage, modified hybrid procedure involving an aortobifemoral bypass without aortic clamping, debranching of right renal, superior mesenteric, and celiac arteries as well as an endovascular repair of the thoracic aneurysm was performed. Unfortunately, despite a technically sound repair, the patient died postoperatively from a massive pulmonary embolism. TAAA with a thrombosed infrarenal aorta and bilateral common iliac arteries can be repaired using a single-stage modified hybrid procedure without aortic clamping in high-risk patients who cannot tolerate thoracotomy and aortic cross clamping.

Although pityriasis versicolor (PV) is a common fungal infection of the skin affecting up to 50% of the population in the tropics, little is known about what patients know, believe, or feel about the condition.
In a cross-sectional questionnaire study of 608 consecutive patients attending the General Outpatient Department and Skin Clinic of a public hospital in Kaduna, Nigeria, self-report of PV, knowledge about its causes, treatments used by patients, and perception and feelings about the condition were assessed.
Overall 608 patients were studied (239/594 [40.2%] males, 355/594 [59.8%] females, age 11–49 years, mean ± SD age of 29.3 ± 10.1). Lifetime self-report prevalence of PV was 271/606 (44.7%) (males: 117/239 [50.0%] females: 148/355 [41.7%] P = 0.09). Three hundred and twenty-seven of 608 (53.8%) patients believed PV was transmitted from another person while 204/608 (33.6%) believed the condition was caused by poor personal hygiene. One hundred and thirty of 608 (21.4%) thought PV was caused by fungi living on the skin. Virtually all respondents who had PV had used at least one preparation with more than half visiting a healthcare facility. A total of 305/608 (50.2%), 189/608 (31.1%), and 142/608 (23.4%) respondents reported feeling or likely feeling uncomfortable, embarrassed, or ashamed, respectively, about PV. Being considered a dirty person (45.6%) and being avoided by other people (28%) were common concerns of respondents.
Most patients did not know what caused PV, and many were uncomfortable, embarrassed, and ashamed, and feared being considered dirty and avoided by others.
This case report details a 51-year-old man with Alport's syndrome resulting in chronic nephritis with stable renal function and sensorineural deafness. The patient was being investigated for persistently raised potassium refractory to dietary and pharmacological modification. Subsequently, the patient was found to have type 4 renal tubular acidosis, and potassium normalised with the addition of fludrocortisone.
We present the case of 60-year-old man with type 2 diabetes who developed blistering after two sequential exposures to linagliptin. Linagliptin is one of the dipeptidyl peptidase 4 (DPP-4) inhibitors, a group of oral hypoglycaemic agents used commonly for the treatment of type 2 diabetes. On the first exposure to linagliptin, he developed blisters on the hands which resolved after stopping the drug. After repeat exposure, he developed two large blisters on the left foot, which burst giving rise to secondary infection, requiring hospital admission for treatment. We discuss the latest research linking DPP-4 inhibitors with adverse skin reactions and the effect of ulcers on the morbidity and mortality of patients with diabetes. This case report highlights skin reactions as an important, rare and lesser known side effect of DPP-4 inhibitors.
Description
A previously fit and well middle-aged woman presented with a 24-hour history of deteriorating breathlessness and rigors. The patient showed signs of acute respiratory distress. She was febrile, tachycardic and had a loud pansystolic murmur at the cardiac apex. A chest radiograph showed right lower zone consolidation, and an ECG showed sinus tachycardia. Blood tests showed raised inflammatory markers with white cell count of 11.8x109/L (normal range 4–10x109/L) and C reactive protein 56 mg/L (normal range 0–10 mg/L). A transthoracic echocardiogram identified severe mitral regurgitation secondary to posterior mitral valve leaflet prolapse with a hyperdynamic left ventricle. Peripheral blood cultures were negative.
The patient was treated for community-acquired pneumonia and presumed endocarditis. A transoesophageal echocardiogram (TOE) confirmed severe mitral regurgitation secondary to a flail posterior mitral valve scallop (P2) with ruptured primary and secondary chords. There was also a posterior leaflet calcium spur and a vegetation. In addition, the TOE demonstrated a...
We presented a case of a postoperative patient with low-flow priapism, possibly initiated by propofol-based anaesthesia or epidural anaesthesia. The delay in diagnosing priapism resulted in emergency interventions with a partially successful effect and eventually permanent erectile dysfunction. Due to the delay in treatment, erectile dysfunction ensued and was manageable with medication; hence, the patient decided against a penile prosthesis.
We present a rare case of rectosigmoid malakoplakia treated with fluoroquinolone.
Renal failure in cases of acute lymphoblastic leukaemia during induction is mainly because of sepsis and tumour lysis syndrome. This 18-year-old man had sudden onset anuria with increase in creatine. At this time, patient did not have any overt signs or laboratory features suggestive of sepsis. Imaging studies documented bilateral hydronephrosis. Ureteroscopy was done, and it showed presence of soft tissue mass obstructing the ureter. On the the left side, it was noted in its middle part and on the right, at the ureteropelvic junction. The mass on the left side was removed under ureteroscopic guidance and was sent for histopathology examination. It was confirmed to be fungal ball on histopathology examination. Though rare, even in immunocompromised patients, bilateral fungal ball should be considered in differential diagnosis in cases of acute leukaemia with sudden onset anuria. We share our experience in managing this case for which there are no clear guidelines.
A 49-year-old man presented in the emergency department with altered sensorium and renal failure and was placed on a ventilator. Evaluation with MRI of the brain showed enhancing lesion in the occipital lobe. Biochemical tests revealed elevated calcium and parathyroid hormone (PTH) levels. Further evaluation revealed multiple lesions at both lobes of the lungs and nodular lesion in the right inferior pole of the thyroid. Diagnosis of metastatic parathyroid carcinoma was suspected. Patient was stabilised with bisphosphonates and haemodialysis and planned for surgery. Intraoperatively a hard lesion was found in the right inferior parathyroid infiltrating the surrounding structures. En bloc resection was done. General condition of the patient improved and he was weaned from the ventilator. Histopathology confirmed the diagnosis of parathyroid carcinoma. Postoperatively, there was persistent elevation of PTH in spite of a fall in calcium levels indicating functioning brain and pulmonary metastases. Due to extensive metastases, the patient was given palliative cinacalcet and was kept under follow-up.
Fascioliasis is a zoonotic disease that can sometimes affect humans. It presents with non-specific signs and symptoms which makes it difficult to establish an early definitive diagnosis. This can be particularly true in non-endemic countries where a high degree of suspicion is needed to make the diagnosis. Another confounding factor is that many of the initial complains and findings are very similar to those of malignancy. We report a case of an otherwise healthy 47 year-old male presenting with abdominal pain, night-time sweating, anorexia, weight loss and loose stools that had several hepatic nodules visible in the abdominal CT scan. Although the initial hypothesis was hepatic malignancy or liver metastasis of unknown primary neoplasm, the workup performed led us to the correct diagnosis. He was treated successfully for hepatic fascioliasis, with a full recovery.

A 48-year-old man with a history of coronary heart disease underwent a left heart catheterisation for non-ST-segment myocardial infarction. Coronary angiography revealed significant stenosis of the left anterior descending artery and right coronary artery (LAD/RCA). Transthoracic echocardiogram showed severely dilated left ventricle (LV), moderate concentric LV hypertrophy, an LV ejection fraction of 26% and elevated right ventricular systolic pressure of 40–45 mm Hg. An intra-aortic balloon pump (IABP) was placed for haemodynamic support through a right femoral artery insertion site. The patient later received a saphenous vein graft (SVG) to the RCA, an SVG to the left obtuse marginal artery and a left internal mammary artery graft to the LAD. On the postoperative chest X-ray, the IABP was visualised overlying the right hilar region, thatevoked alarming concern of possible misinsertion into the superior vena cava (SVC) through an arteriovenous fistula or through the femoral vein (figure 1). Delayed...
There is no widely accepted intervention in the prevention of acute mucositis during chemoradiotherapy for head and neck carcinoma. In the present double-blind study, we tested 4 natural agents, propolis, aloe vera, calendula, and chamomile versus placebo.
Patients undergoing concomitant chemo-intensity-modulated radiotherapy (IMRT) were given natural agent or matched placebo; grade 3 mucositis on physical examination according to Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 was the primary endpoint. Various covariates were tested at logistic regression, including the individual amount of mucosa receiving at least 9.5 Gy per week (V9.5w).
One hundred seven patients were randomized from January 2011 to July 2014, and 104 were assessable (51%-49% were assigned to the placebo group and 53%-51% were assigned to the natural agent). Overall, 61 patients developed peak grade 3 mucositis with no difference between arms (P = .65). Conversely, V9.5w (P = .007) and primary site (P = .037) were independent predictors.
The selected natural agents do not prevent mucositis, whereas the role of V9.5w is confirmed.
In literature, no markers have been reported as predictive and prognostic factors in osteosarcoma of the jaw.
A retrospective analysis of p16 expression was performed in 37 patients with high-grade osteosarcoma of the jaw to investigate its potential prognostic and predictive value.
p16 positivity was found in 56.7% of cases. The absence of p16 expression was associated with an adverse disease-free survival (P = .003). At the multivariate Cox regression, positive margins were the only independent factor. In the subgroup of 17 patients who underwent neoadjuvant chemotherapy, a significant association was noted between p16 expression and pathological response to chemotherapy (P = .015) and the negativity of p16 increased the risk of negative outcome (P = .01).
Our data indicate that the wide surgical margin is the most important prognostic factor. The expression of p16 confers greater sensitivity to chemotherapy and its loss of expression is associated with a worse prognosis.
Currently, positive surgical margins in head and neck cancer are considered to be an indicator for postoperative chemoradiotherapy (CRT) over radiotherapy (RT) alone. However, there are less data regarding the impact of margin status on human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (SCC).
We performed a retrospective review of 55 patients with oropharyngeal SCC undergoing primary surgical treatment. The impact of margin status on disease-specific survival (DSS) was studied according to p16 status.
Twenty-one patients had positive margins. Adjuvant treatment in these cases was CRT (n = 6), RT alone (n = 14), and none (n = 1). Among p16-negative patients, positive margins and dysplasia at margins predicted significantly worse DSS. Among patients with p16-positive disease, margin status had no impact on DSS.
Patients with p16-positive oropharyngeal SCC and positive margins after excision maintain a low risk of recurrence despite most receiving RT alone as adjuvant treatment. These findings raise questions regarding the additional benefit of postoperative CRT in this group.
Despite the importance of ultrasound imaging in thyroid disease care, ultrasound reports vary greatly in the features described. It is essential that ultrasound reports contain and present all components necessary for a clinical decision in a reader-friendly format.
One hundred ninety thyroid and neck ultrasound reports were scored using the universal ultrasound report template developed by Su et al, along with the American Thyroid Association (ATA) and the American Association of Clinical Endocrinologists/Associazione Medici Endocrinologi/European Thyroid Association (AACE/AME/ETA) guidelines. All ultrasounds were performed on patients seen between August and November 2015 by a single surgeon (M.L.U), and originated from a variety of physicians and institutions.
An average of 30.9% of Su et al's criteria was satisfactorily included in the reports. Similar results were reached when the ATA and the AACE/AME/ETA guidelines were applied as scoring templates.
Our results reveal the wide variation in ultrasound reporting. The standardization of ultrasound reporting would help to improve physicians' ability to properly diagnose and manage patients with thyroid disease. © 2017 Wiley Periodicals, Inc. Head Neck, 2017
Description
A female aged 94 years with a history of diabetes presented with acute onset abdominal pain, haematemesis and altered mental status. She denied alcoholism, corrosive ingestion, pancreatitis or abdominal trauma. She appeared toxic and was hypotensive. Her hemogram showed leucocytosis at 14.8 x 10^9/L. CT scan of the abdomen showed air scattered within the liver, portal vein and gastric wall (figures 1 and 2). Also, dense calcifications of the aorta and abdominal arteries were noted (figure 3). Due to the high risk of surgery, she was managed conservatively with proton pump inhibitors, broad-spectrum antibiotics, nasogastric decompression and intravenous hydration, with progressive improvement noted.
