Hypospermia Improvement in Dogs Fed on a Nutraceutical Diet

Male dog infertility may represent a serious concern in the canine breeding market. The aim of this clinical evaluation was to test the efficacy of a commercially available nutraceutical diet, enriched with Lepidium meyenii, Tribulus terrestris, L-carnitine, zinc, omega-3 (N-3) fatty acids, beta-carotene, vitamin E, and folic acid, in 28 male dogs suffering from infertility associated with hypospermia. All dogs received the diet over a period of 100 days. At the end of the evaluation period, no adverse effects, including head and tail anomalies percentage onset, were reported. Interestingly, motility percentage, semen volume and concentration, and total number of sperms per ejaculation significantly increased. Further investigations on a wider cohort of dogs might be useful to better correlate the presence of oxytetracycline in pet's diet and the onset of infertility and clearly assess the action mechanism of an oxytetracycline-free nutraceutical diet.

Inequalities in healthcare access: how a man with exstrophy in rural India coped

We report a case of a 22-year-old man with adult exstrophy. The patient made a self-made urine collection device, which helped him to lead a normal life, carrying out his routine as well as occupational activities smoothly. This patient is a prime example of inequalities in healthcare distribution in low-income and middle-income countries. He was never taken to a proper medical centre to correct his condition nor was his mother ever given proper antenatal healthcare access. His background of being a poor person from rural India highlights the problems of inequalities in healthcare access.

Symmetry arguments against regular probability: A reply to recent objections

Abstract

A probability distribution is regular if it does not assign probability zero to any possible event. While some hold that probabilities should always be regular, three counter-arguments have been posed based on examples where, if regularity holds, then perfectly similar events must have different probabilities. Howson (2017) and Benci et al. (2018) have raised technical objections to these symmetry arguments, but we see here that their objections fail. Howson says that Williamson's (2007) "isomorphic" events are not in fact isomorphic, but Howson is speaking of set-theoretic representations of events in a probability model. While those sets are not isomorphic, Williamson's physical events are, in the relevant sense. Benci et al. claim that all three arguments rest on a conflation of different models, but they do not. They are founded on the premise that similar events should have the same probability in the same model, or in one case, on the assumption that a single rotation-invariant distribution is possible. Having failed to refute the symmetry arguments on such technical grounds, one could deny their implicit premises, which is a heavy cost, or adopt varying degrees of instrumentalism or pluralism about regularity, but that would not serve the project of accurately modelling chances.

Self-Reported Benefit and Satisfaction with a Beamforming Body-Worn Hearing Aid for Elderly Adults

Hearing impairment is a leading cause of disability globally and is particularly prevalent in elderly populations. Hearing aids are commonly recommended to mitigate the adverse effects on communication associated with hearing loss. However, the acceptability of hearing aids to elderly individuals is low and the majority of potential users do not wear hearing aids. Most hearing aids are designed with a discreet form factor in mind, to minimize device visibility. Given the range of comorbidities associated with hearing loss in the elderly, this conventional form factor may not always be optimal. The present study examined the experiences of elderly individuals with a recently developed, unconventional, body-worn hearing instrument, the EasyHear™ Grand (Logital Co. Ltd., Hong Kong). The bilaterally fitted instrument incorporates large controls, a color display, beamforming sound processing, and Bluetooth capabilities. Forty-three elderly participants (mean age=71; range 46-88 years) were surveyed to gauge level of benefit and satisfaction with the device and opinions regarding the hearing aid. They were assessed using three standardized questionnaires (the International Outcome Inventory-Hearing Aids, the Profile of Hearing Aid Benefit, and the Client Oriented Scale of Improvement) and through open-ended, structured interviews. Participants rated their EasyHear device fitting highly for hours of use and improved quality of life and rated the device favorably for improved communication and benefit in background noise. A majority of users felt the device improved listening ability in their expressed area of greatest need, and also for their second highest prioritized area of greatest need. Less than 10% of users felt their listening was only occasionally or hardly ever improved when using the body-worn device. Benefit and satisfaction ratings with the EasyHear Grand were comparable to those in studies involving conventional form factor devices. Interviews highlighted areas where users felt the device could be improved—extra noise reduction, changes to device dimensions, receiver/eartip fit, and cableless technology were among the areas mentioned. Many participants valued smartphone linkage and Bluetooth capability. The EasyHear Grand, with its body-worn design and large, simple controls, was well accepted by the majority of participants. Hearing aids that break from conventional design formats may benefit many elderly individuals with hearing impairment and promote increased user acceptability.

Clinical Indices to Drive Quality Improvement in Otolaryngology

A Pediatric Tracheostomy Care Index (PTCI) was developed by the authors to standardize care and drive quality improvement efforts at their institution. The PTCI comprises 9 elements deemed essential for safe care of children with a tracheostomy tube. Based on the PTCI scores, the number of missed opportunities per patient was tracked, and interventions through a "Plan-Do-Study-Act" approach were performed. The establishment of the PTCI has been successful at standardizing, quantifying, and monitoring the consistency and documentation of care provided at the authors' institution.

Patient Engagement in Otolaryngology

Patient engagement, which involves incorporating the patient and family as partners in their care, is a growing focus in otolaryngology and surgery. Attention to patient and family centeredness, shared decision making, and patient experience together improves the overall tenor of patient engagement. Patient engagement promotes safety through improving quality of electronic health record data, error detection, and treatment decisions and adherence. In this article, we review specific areas of importance for patient engagement in otolaryngology as well as areas needing more research and development.

Regional Node Distribution in Papillary Thyroid Cancer with Microscopic Metastasis

Background. Optimal neck lymphadenectomy in patients with papillary thyroid cancer (PTC) and microscopic lymph node metastasis needs to be defined in order to aid surgeons in their decision about the best way to proceed in these cases. Methods. Patients who underwent total thyroidectomy and lymphadenectomy at levels IIa to VI were divided into two groups: Group 1 (G1) with macroscopic metastasis detected before surgery and Group 2 (G2) with microscopic metastasis detected in sentinel node during surgery. Odds ratio (OR) was computed for age, sex, tumor size, multicentricity, capsular invasion, vascular/lymphatic permeation, and nodes with metastasis. Results. Primary tumor size was (G1 versus G2, respectively) 3.8 cm versus 1.98 cm (P

Necrotizing Neutrophilic Dermatitis, an Often-Misdiagnosed Entity With Potentially Severe Consequences

I first became aware of the diagnosis of pyoderma gangrenosum (PG) early in my dermatology residency when I encountered a patient diagnosed with ulcerative colitis who presented with fever and hundreds of vesiculopustular lesions on her face, trunk, and extremities, several of which developed into typical lesions of classic PG. Within weeks of seeing that patient, I cared for another patient with a known diagnosis of agnogenic myeloid metaplasia with an atypical, superficial variant of PG that has been described more frequently on the upper extremities and face in association with a myeloid preleukemic process. This rare ulcerative disease, first described in 1930 by Brunsting et al, was something I heard little of during medical school or my medicine residency. However, within the initial year of my dermatology residency I had become involved with multiple cases of PG and I was hooked on investigating the literature, writing about my experiences with misdiagnoses and management of patients beyond the use of systemic corticosteroids. From 1977, when my first publication on this entity appeared in this journal, until today, I have been an author or coauthor on 28 publications about PG. The most recent publication is part of a Delphi project to develop improved diagnostic criteria that went beyond the statement by Perry in 1969 that "the diagnosis of a skin lesion as pyoderma gangrenosum (PG) is dependent entirely upon the clinical evaluation of the lesion. Unfortunately, there are no characteristic histopathologic changes or abnormalities on laboratory tests."^(p899)

Arterial Stiffness in a Toddler with Neurofibromatosis Type 1 and Refractory Hypertension

Arterial hypertension is a common finding in patients with neurofibromatosis (NF) type 1. Renovascular hypertension due to renal artery stenosis or midaortic syndrome could be the underlying cause. We report the case of a 4-year-old girl with NF type 1 and midaortic syndrome whose changes in blood pressure and pulse wave velocity suggested the evolution of vasculopathy, diagnosis of renovascular hypertension, and provided insights of response to treatment. Hypertension persisted after percutaneous transluminal angioplasty in the abdominal aorta, requiring escalation of antihypertensive treatment, while arterial stiffness demonstrated a mild decrease. Regular assessment of blood pressure using ambulatory blood pressure monitoring and noninvasive assessment of arterial stiffness may enhance the medical care of patients with NF type 1.

Sialendoscopy for Definitive Management of a Submandibular Abscess following Radiotherapy for Oropharyngeal Squamous Cell Carcinoma

Background/Aims: Sialendoscopy has as yet been shown to be ideal for the management of sialolithiasis and chronic inflammatory diseases of the salivary gland. However, its applicability to the management of a broad range of salivary gland disease is continually growing. Methods: Here we present a case report where sialendoscopy was used to successfully manage an intraparenchymal submandibular gland abscess in a patient with oropharyngeal squamous cell carcinoma managed with primary chemoradiation. Results: The use of sialendoscopy enabled visualization of the patency of salivary ducts, drainage of abscess, and irrigation of antibiotic-impregnated fluid. In this particular patient, we were able to avoid a transcervical approach through a previously irradiated field, which would have necessitated concurrent tracheostomy and placed undue risk to surrounding neurovascular structures. Conclusion: Sialendoscopy should thus, in select patients, be considered as an initial intervention for patients with intraparenchymal salivary gland abscesses in which prior therapy creates an increased risk of complication from an open transcervical approach.

High-risk drug rashes

Publication date: November 2018

Source: Annals of Allergy, Asthma & Immunology, Volume 121, Issue 5

Author(s): Sasha A. Alvarado, Diana Muñoz-Mendoza, Sami L. Bahna

Abstract

Objective

To provide a brief overview of the clinical presentation, common offending agents, management, prognosis, and mortality of 6 selected high-risk drug rashes, namely, Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome, multiple drug hypersensitivity (MDH) syndrome, acute generalized exanthematous pustulosis (AGEP), and drug-induced bullous pemphigoid (DIBP).

Data Sources

A review of the published literature was performed with PubMed and supplemented with our clinical experience.

Study Selections

The most recent clinically relevant studies and older seminal works were selected.

Results

Most of the published data on these uncommon rashes were based on small observational series or case reports. SJS and TEN have specific genotypes association with certain drugs, have high morbidity and mortality, and require aggressive management by a team of multiple specialists. DRESS syndrome is a severe, prolonged multiorgan reaction, yet it has a better prognosis than TEN. MDH is a syndrome of repeated reactions to unrelated drugs that often imposes diagnostic and management difficulties. AGEP consists of generalized sterile small pustules, usually mistaken for infection with subsequent inappropriate treatment. Bullous pemphigoid presents with tense pruritic bullae and characteristic linear basement membrane deposition of IgG and C3. DIBP has much better prognosis than the autoimmune variety.

Conclusion

In such high-risk drug rashes, early recognition, immediate withdrawal of the suspected drug(s), prompt individualized management, and monitoring of vital organs function are mandatory for reducing morbidity and mortality. The lack of reliable tests for identification of the causative agent imposes difficulty, particularly in patients receiving multiple medications.

Systematic review of professional liability when prescribing β-lactams for patients with a known penicillin allergy

Publication date: November 2018

Source: Annals of Allergy, Asthma & Immunology, Volume 121, Issue 5

Author(s): Meghan N. Jeffres, Elizabeth A. Hall-Lipsy, S. Travis King, John D. Cleary

Abstract

Objective

To describe medical negligence and malpractice cases in which a patient with a known penicillin allergy received a β-lactam and experienced an adverse reaction related to the β-lactam.

Data Sources

Lexis-Nexus, Westlaw, and Google Scholar were searched.

Study Selections

Medical negligence and malpractice cases were eligible for inclusion if they met the following criteria: the plaintiff had a known penicillin allergy, received a β-lactam, and experienced an adverse event. All United States federal and state cases were eligible.

Results

Twenty-seven unique cases met the inclusion criteria. Eighteen cases involved the receipt of a penicillin-based antibiotic; of these cases with a known legal outcome, the plaintiff (patient or representative) prevailed or settled in 3 cases and defendants (providers) prevailed in 7 cases. Seven cases involved the receipt of a cephalosporin; of these cases with a known legal outcome, the plaintiff settled with physicians before trial in 1 case and defendants prevailed in 3 cases. Two cases involved the receipt of a carbapenem. Defendants prevailed in one case and the legal outcome of the other case is unknown. In cases in which the defense successfully moved for summary judgment, judges cited a lack of scientific evidence demonstrating a cephalosporin or carbapenem was contraindicated for a patient with a penicillin allergy.

Conclusion

The cases with published legal outcomes found limited professional liability for clinicians who prescribed cephalosporins or carbapenems to a patient with a known penicillin allergy. These results may decrease the litigation fears of practitioners and risk managers within health care systems.

Résumé

Introduction

Le syndrome de Griscelli (SG) est une maladie génétique autosomique récessive rare, caractérisée par une dilution pigmentaire des cheveux et de la peau. Nous rapportons un cas de syndrome de Griscelli de type 3 diagnostiqué à un âge tardif.

Observation

Une femme de 31 ans présentait depuis l'enfance une dépigmentation des cheveux et des sourcils avec une discrète leucodermie diffuse. L'étude microscopique du cheveu mettait en évidence des agrégats de mélanine irrégulièrement distribués le long de la tige pilaire. Le séquençage de l'ADN montrait une mutation homozygote C103T (R35W) dans l'exon 1 du gène MLPH, correspondant au syndrome de Griscelli type 3.

Discussion

Trois phénotypes cliniques de SG ont été décrits selon le défaut moléculaire sous-jacent. Les SG types 1 et 2 sont associés respectivement à un dysfonctionnement du système nerveux central et à un déficit immunitaire. Le SG type 3 est une forme cutanée isolée. L'examen microscopique des cheveux permet de poser le diagnostic. Seuls 15 cas de SG type 3 ont été décrits dans la littérature, neuf de sexe masculin et six de sexe féminin. L'âge moyen au diagnostic est de 12 ans. Dix des cas sont d'origine arabe, quatre d'origine turque et un d'origine indienne. La mutation R35W a été observée dans neuf cas et les mutations E98X et R35Q chacune dans un cas.

Conclusion

Le syndrome de Griscelli doit être évoqué devant tout aspect de cheveux gris argentés, plus particulièrement chez des patients d'origine arabe ou turque.

Summary

Introduction

Griscelli syndrome (GS) is a rare autosomal-recessive genetic disease characterized by hypopigmentation of skin and hair. We report a case of GS type 3 with late diagnosis.

Observation

A 31-year-old female patient had presented depigmentation of the hair and eyebrows as well as diffuse skin hypopigmentation during childhood. Microscopic analysis of a hair shaft revealed irregularly distributed clumps of melanin. DNA sequencing showed a homozygous C103T (R35W) transition in exon 1 of MLPH, confirming Griscelli syndrome type 3.

Discussion

Three clinical phenotypes of GS have been described based on the underlying genetic defect. GS type 1 and 2 are associated respectively with a central nervous system dysfunction and an immune defect. GS type 3 is an isolated cutaneous form. Diagnosis is confirmed on microscopic examination of hair shafts. 15 cases of GS type 3 have been reported: 9 in males and 6 in females. Mean age at diagnosis is around 12 years. Nine of the reported patients were of Arab origin, four of Turkish origin, and one of Indian origin. R35W mutation was described in 9 cases and E98X and R35Q mutations were each found in one case.

Conclusion

GS should be suspected in patients presenting gray silvery hair, particularly when these patients are of Arab or Turkish origin.

Parent Perspectives on Multidisciplinary Pediatric Hearing Healthcare

Publication date: Available online 31 October 2018

Author(s): Ursula M. Findlen, Prashant S. Malhotra, Oliver F. Adunka

Abstract

Introduction

Family-centered healthcare demands that families provide input regarding the care of their children. Very little is known, however, about how families perceive their experience in different types of multidisciplinary team models, and specifically, in the multidisciplinary setting currently utilized in many pediatric hearing clinics.

Methods

Quantitative and qualitative parent survey responses were collected and analyzed in a tertiary care pediatric medical center after a one-day multidisciplinary assessment clinical appointment. Questions pertained to information across five domains, including overall experience, diagnosis, treatment plan formulation, additional testing, and resources. Quantitative responses were analyzed descriptively while qualitative responses were evaluated using content analysis to derive themes. Quantitative and qualitative data were evaluated separately and then compared to delineate themes for strengths and weaknesses.

Results

Overall, high satisfaction was evident in both quantitative and qualitative responses. Results suggested that a one-day multidisciplinary assessment appointment may contribute to parents feeling overwhelmed by information shared and not fully understanding which disciplines are providing care. Analysis revealed a specific area of weakness in our particular setting was inadequate provision of information about functional hearing (e.g., listening socially and academically). Results contributed to a change from a multidisciplinary team model to an interdisciplinary care coordination approach to pediatric hearing healthcare.

Conclusions

Understanding parent perspectives and expectations is the corner stone of family-centered care and may ultimately influence a child's developmental outcome. A systematic way of evaluating parent perspectives on the clinical process can influence service delivery and help children with hearing loss meet their potential.

Cost-effectiveness of nivolumab in the treatment of head and neck cancer

Publication date: December 2018

Source: Oral Oncology, Volume 87

Author(s): A. Hirschmann, J.E. Lupatsch, M. Schwenkglenks, C.M. Panje, K. Matter-Walstra, V. Espeli, K.J. Dedes, M. Siano, for the Swiss Group of Clinical Cancer Research (SAKK)

Abstract

Background

Until recently, no second-line treatment for recurrent and/or metastatic head and neck squamous cell cancer (r/mHNSCC) was able to improve overall survival (OS). Nivolumab has become a promising treatment for r/mHNSCC. The CheckMate-141 trial showed that nivolumab improves OS compared to investigator's choice (IC) (cetuximab, methotrexate, docetaxel). Treatment with immune checkpoint inhibitors is however expensive. The aim of this analysis was to assess the cost-effectiveness of nivolumab as second-line treatment for r/mHNSCC in Switzerland.

Methods

Based on the CheckMate-141 trial, we constructed a Markov model comparing nivolumab to IC, including follow-up data up to 24 months. We assessed costs for treatments from the perspective of the Swiss health system with a 60 months' time horizon. PD-L1 and p16 testing were considered in scenarios. Incremental cost-effectiveness ratios (ICER) were compared to an informal willingness-to-pay of CHF (Swiss Francs) 100,000 per QALY gained.

Results

For the base case we estimated an incremental effectiveness of 0.35 QALYs and incremental costs of CHF 35,562 with nivolumab, resulting in an ICER of CHF 102,957 per QALY gained. Most influential drivers for the ICER were the price of nivolumab and the progressive disease state utility weights. In 45.5% of probabilistic sensitivity analysis simulations nivolumab was estimated below 100,000 CHF/QALY. Reducing the price of nivolumab according to a consented payback by 4.75%, resulted in an ICER of CHF 98,325/QALY gained.

Conclusions

At current prices nivolumab has an ICER of around CHF 100,000 per QALY gained in the second line treatment of r/mHNSCC patients in Switzerland.

Abstract

The mechanism of the efficacy of Intravenous immunoglobulins (IVIG) in autoimmune and inflammatory diseases is not well understood. This study aimed at understanding mechanisms of IVIG-mediated suppression of effector cell activities of peripheral blood mononuclear cells (PBMC) in antibody-dependent cellular cytotoxicity (ADCC). We were particularly interested in CD56^dim NK cells, the main ADCC effector cells in PBMC. Exposure of PBMC to IVIG for at least 48 h induced a caspase-3-dependent apoptotic cell death of CD56^dim NK cells without affecting CD56^bright NK cells. Induction of apoptosis in CD56^dim NK cells and concomitant suppression of ADCC effector activities of PBMC was associated with the monomer fraction of IVIG. Moreover, it was independent of IgG sialyation, did not depend on engagement of FcγRIII and could not be mimicked by IVIG (Fab')₂ or IVIG Fc preparations. The described effect could contribute to the reduction of peripheral NK cells observed during IVIG therapy in patients.

Migraine increases the proportion of sudden sensorineural hearing loss: A longitudinal follow-up study

Publication date: Available online 30 October 2018

Source: Auris Nasus Larynx

Author(s): So Young Kim, Mi Kyung Kim, Jae-Sung Lim, Il Gyu Kong, Hyo Geun Choi

Abstract

Objective

The aim of the present study was to investigate the proportion of sudden sensorineural hearing loss (SSNHL) patients in a representative population cohort with migraine.

Methods

The Korean National Health Insurance Service-National Sample Cohort was collected from 2002 to 2013. A total of 45,114 migraine participants (the migraine group) were matched according to age, sex, income, region of residence, hypertension, diabetes, and dyslipidemia with 180,456 controls (the control group). The migraine group included participants diagnosed with migraine (International Classification of Disease [ICD]-10: G43) who underwent treatment ≥2 times. The SSNHL was investigated based on the ICD-10 (H912) code and confirmed by an audiometry exam and steroid treatment. Histories of hypertension, diabetes, dyslipidemia, ischemic heart disease, stroke, depression, Meniere's disease, and tinnitus were evaluated using ICD-10 codes. Crude (simple) and adjusted hazard ratios (HRs) of SSNHL associated with migraine were analyzed using the Cox proportional hazards model. Subgroup analyses were conducted according to age and sex.

Results

In total, 0.9% (399/44,714) of the migraine patients and 0.6% (1,169/179,287) of the controls were diagnosed with SSNHL (P < 0.001). The adjusted HR of migraine for SSNHL was 1.34 (95% confidence interval [CI] = 1.19–1.50, P < 0.001). Both patient age subgroups (20–59 years old and ≥60 years old) showed high adjusted HRs for SSNHL. Both the men and women presented an elevated proportion of SSNHL cases.

Conclusion

Migraine patients had a higher likelihood of SSNHL. All age and sex migraine subgroups showed an elevated proportion of SSNHL cases.

Evaluation of folded amniotic membrane and injectable amniotic membrane pieces as soft tissue filler materials

Publication date: Available online 30 October 2018

Source: Auris Nasus Larynx

Author(s): Mustafa Caglar Buday, Murat Ozturk

Abstract

Objective

The search for safe and effective tissue fillers has been an ongoing effort for many years. Obtaining biological materials from patients can require additional incisions and brings surgical and cosmetic risks as a major disadvantage. The aim of this experimental study was, therefore, to evaluate the efficacy of folded amniotic membrane as a soft tissue filler and to assess its volume, and to investigate the possible usage of injectable amniotic membrane for augmentation.

Methods

Multi-layer amniotic membranes are transplanted to the subcutaneous tunnels created in the rat's back, and the amniotic membrane transformed into the injection material is inoculated transcutaneously under the rat's skin. At the end of two months, the amount of volume loss and histopathological changes in the grafts were examined under light microscope.

Results

The multi-layer amniotic membrane grafts maintain its volume around 92%. It has been shown that the injectable amniotic membrane maintains its presence in the tissue, can augment it, and can be used as a soft tissue filler. The availability of using amniotic membrane for injection material is shown. No foreign body reaction to the amnion grafts, fibrosis, and necrosis were observed in our study.

Conclusion

According to our study results, multi-layer amnion graft and amnion injection seem to be used as camouflage grafts and soft tissue augmentation materials. Although further clinical trials are mandatory before considering the use of amniotic membrane as a tissue filler material in humans, we are hopeful about its long-term safety and efficacy.

Stapes hypermobility as a possible cause of hyperacusis

Publication date: Available online 31 October 2018

Source: American Journal of Otolaryngology

Author(s): Herbert Silverstein, Joshua Smith, Brian Kellermeyer

Abstract

Objective

Hyperacusis is a reduction of normal tolerances for everyday sounds. Although several publications have been produced demonstrating that minimally invasive surgical procedures may improve patient symptoms, the precise etiology of hyperacusis often remains elusive. This study describes 21 patients, 7 of whom stapes hypermobility is believed to be a mechanical genesis of their hyperacusis symptoms.

Study design

A prospective, repeated-measure single-arm design was used for this study.

Setting

All patients were evaluated and treated at a tertiary level otologic referral center.

Subjects and methods

21 patients (Cohort A) with severe hyperacusis underwent oval and round window reinforcement. Seven patients (Cohort B) intraoperatively appeared to have subjective hypermobility of the stapes. Additional reinforcement of the stapes superstructure was performed in these patients.

Results

In Cohort A, loudness discomfort level (LDL) values improved on average from 72.7 dB to 81.9 dB. Hyperacusis questionnaire (HQ) scores improved from 30.1 to 14.7. Numeric Rating Scale scores (0−10) decreased from 8.5 to 4.0. In Cohort B, values similarly improved from an average of 72.4 dB to 88.2 dB. HQ scores improved from 35.8 to 18.9. Numeric Rating Scale scores fell from 10.0 to 3.7. Postoperatively there were no complaints of hearing loss. Sixteen out of 21(76%) reported improved quality of life and diminished symptoms of hyperacusis.

Conclusion

It is possible that patients suffering from hyperacusis may have a mechanical cause for their symptoms. Further research is necessary to clarify stapes mobility in patients with these symptoms. Excess temporalis tissue reinforcement of the stapes along with round window reinforcement shows promise as a minimally invasive surgical option for patients suffering from hyperacusis.

Roles of functional strain and capsule compression on mandibular cyst expansion and cortication

Publication date: Available online 30 October 2018

Source: Archives of Oral Biology

Author(s): Babak Sarrafpour, Charbel El-Bacha, Qing Li, Hans Zoellner

Abstract

Objective

Cyst expansion in bone involves bone resorption but is often accompanied by adjacent bone formation with cortication. The mechanisms for these two apparently opposite processes remain unclear. From a mechanobiological perspective, functional strain drives bone remodeling, which involves both bone apposition and resorption. In this study, we explore the role of functional strain in cyst growth.

Design

Using a three-dimensional finite element analysis model of a simulated cyst at the of right first mandibular molar mesial apex, we examined three loading conditions, representing biting on the right molar, left molar and incisors, respectively. Comparison was made with an identical finite element model without the simulated cyst.

Results

Under all loading conditions, finite element analysis revealed higher strain energy density within the bone lining the cyst compared with the non-cyst model, which is consistent with bone formation and cortication observed clinically. Further analysis demonstrated overall compression of the simulated cyst capsule under all loading conditions.We interpret compression of the capsule as indicating resorption of the adjacent bone surface.

Conclusions

We conclude that functional stress results in dominant compression of the soft tissue capsules of bony cysts, contributing to cyst expansion. Also, functional strain becomes elevated in the bone immediately adjacent to the soft tissue cyst capsule, which may drive bone formation and cortication.

Background

Wheat is a common food allergen that can cause anaphylaxis.

Objective

We sought to determine the efficacy and safety of vital wheat gluten (VWG) oral immunotherapy (OIT).

Methods

After baseline double-blind, placebo-controlled food challenge (DBPCFC), 46 patients with wheat allergy (median age, 8.7 years; range, 4.2-22.3 years) were randomized 1:1 to low-dose VWG OIT or placebo, with biweekly escalation to 1445 mg of wheat protein (WP). After a year 1 DBPCFC, active subjects continued low-dose VWG OIT for another year and underwent a year 2 DBPCFC and, if passed, a subsequent off-therapy DBPCFC. Placebo-treated subjects crossed over to high-dose VWG OIT (maximum, 2748 mg of WP).

Results

The median baseline successfully consumed dose (SCD) was 43 mg of WP in both groups. At year 1, 12 (52.2%) of 23 low-dose VWG OIT–treated and 0 (0%) of 23 placebo-treated subjects achieved the primary end point of an SCD of 4443 mg of WP or greater (P < .0001); median SCDs were 4443 and 143 mg, respectively. At year 2, 7 (30.4%) of 23 low-dose VWG OIT–treated subjects were desensitized to an SCD of 7443 mg of WP; 3 (13%) achieved sustained unresponsiveness 8 to 10 weeks off therapy. Among placebo-treated subjects who crossed over to high-dose VWG OIT, 12 (57.1%) of 21 were desensitized after 1 year (median SCD, 7443 mg of WP; nonsignificant vs low-dose VWG OIT). At year 1, skin prick test responses and wheat- and omega-5 gliadin–specific IgE levels did not differ between groups; the low-dose VWG OIT median specific IgG₄ level was greater than placebo (wheat, P = .0005; omega-5 gliadin, P = .0001). Year 1 SCDs correlated with wheat-specific (rho = 0.55, P = .0003) and omega-5 gliadin–specific (rho = 0.51, P = .001) IgG₄ levels in all subjects. Among 7822 low-dose VWG OIT doses in year 1, 15.4% were associated with adverse reactions: 0.04% were severe, and 0.08% subjects received epinephrine. Among 7921 placebo doses, 5.8% were associated with adverse reactions; none were severe.

Conclusions

Low- and high-dose VWG OIT induced desensitization in about one half of the subjects after 1 year of treatment. Two years of low-dose VWG OIT resulted in 30% desensitization, and 13% had sustained unresponsiveness.

Non-operative management of isolated spontaneous superior mesenteric artery dissection

Abstract

Isolated spontaneous superior mesenteric artery (SMA) dissection is a rare differential for patients presenting with abdominal pain. Due to limited cases reported, management strategies have been poorly defined. We present the case of a 49-year-old male with history of hypertension and ischemic colitis, presenting with abdominal pain. CT imaging demonstrated a thrombosed dissection of the SMA extending into second and third order braches. He was managed conservatively with therapeutic anticoagulation. His symptoms improved and upon discharge he was transitioned to aspirin and warfarin. Repeat CT imaging continued to show the dissection with resolution of the SMA thrombus. Spontaneous SMA dissection is exceedingly rare with no universally agreed upon standard of care for treatment. Operative intervention should be reserved for failed conservative management or vascular compromise. Understanding the current treatment options helps ensure a favorable patient outcome.

Malignant proliferating trichilemmal tumor of the forearm: a case report of an unusual location of a rare cutaneous adnexal tumor

Abstract

Proliferating trichilemmal tumor (PTT) is a rare cutaneous adnexal neoplasm of the hair follicle that undergoes outer root sheath differentiation in the isthmus. Histological hallmarks include trichilemmal keratinization, lack of granular layer and lobular proliferation of squamous epithelium with glycogenated clear cells. It affects predominantly elderly women, especially over the scalp. In some cases, malignant transformation can occur. However, only a few cases are reported in the literature. We hereby describe the case of a patient diagnosed with malignant PTT (MPTT) in the dorsal forearm, 2 years after undergoing surgical excision of a squamous cell carcinoma in the same topography. Thus, providing a thorough description of the clinical presentation of MPTT will assist surgeons in diagnosing and treating this rare tumor.

Resection of a mature cystic teratoma of the liver harboring a carcinoid tumor

Abstract

Cystic teratomas are rare pluripotent embryonic tumors which most commonly originate in gonadal organs. Extra-gonadal cystic teratomas are exceedingly uncommon, accounting for only 1% of all cystic teratomas, and have been reported in unusual locations including the kidney, mediastinum and liver. These extra-ovarian cystic teratomas have also been known to harbor other neoplasms including carcinoid tumors. In this report, we describe a unique case of a hepatic cystic teratoma occurring as a combined tumor with a carcinoid in a young female. The patient underwent elective laparoscopic resection of her tumor after extensive radiographic and endoscopic work-up for chronic, non-localizable abdominal pain. We believe the carcinoid tumor arose de novofrom committed differentiation of a cell line within the teratoma, and not metastatic spread.

Decompressive laparotomy for a patient on VA-ECMO for massive pulmonary embolism that suffered traumatic liver laceration after mechanical CPR

Abstract

Massive pulmonary embolism (PE) is an embolus sufficiently obstructing pulmonary blood flow to cause right ventricular (RV) failure and hemodynamic instability. We have utilized veno-arterial extracorporeal membrane oxygenation (VA-ECMO) for early and aggressive intervention for massive PE patients. We present a case of a 61-year-old female placed on VA-ECMO for a massive PE while presenting in cardiac arrest and receiving mechanical cardiopulmonary resuscitation (CPR) via the LUCAS 2.0 device (Physio-Control Inc., Lund, Sweden). The patient suffered a severe liver laceration secondary to mechanical CPR and required a decompressive laparotomy. This case highlights that mechanical CPR during other interventions can lead to malposition of the device and could result in solid organ injury.

Rhabdomyolysis-Induced Acute Kidney Injury in Diabetic Emergency: Underdiagnosed and an Important Association to Be Aware of

Rhabdomyolysis is a potentially life-threatening clinical syndrome associated with muscle injury which can cause a leakage of intracellular contents, manifested from the range of being asymptomatic to a life-threatening condition causing acute kidney injury and severe electrolyte abnormalities. Rhabdomyolysis has been associated with both diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic nonketotic syndrome, though there is an increased association with rhabdomyolysis and acute kidney injury with hyperosmolar nonketonic state compared with patients with diabetic ketoacidosis. Common clinical manifestations are muscle pain, dark urine, and generalized weakness. The causes of rhabdomyolysis are broadly categorized into three groups: traumatic, nontraumatic exertional, and nontraumatic nonexertional. Here, we present a case of rhabdomyolysis-induced acute kidney injury in a patient with hyperosmolar hyperglycemic state. The patient was discharged on insulin and needed intermittent dialysis for two months. Our case highlights the importance of the rare association of rhabdomyolysis causing acute kidney injury in a diabetic emergency.

Characteristics and Outcomes of Liver Transplantation for Primary Biliary Cholangitis (PBC) in Young patients: Analysis of the United Network for Organ Sharing Database

Background Primary biliary cholangitis (PBC) in younger patients has been suggested to require liver transplantation (LT) in early adulthood, but data is limited on its outcomes. We aimed to evaluate the characteristics and outcome of LT in young patients with PBC in comparison with older adults. Methods The United Network for Organ Sharing (UNOS) database was analyzed for all patients with PBC who underwent LT between 2000 and 2012. Based on age at the time of LT subjects were divided into two groups: young patients (≤ 40 years) and older adults (≥ 41 years). Baseline demographics, clinical parameters, and outcomes of LT were then compared between the two groups. Univariable and multivariable analyses were performed to assess the factors associated with outcomes of LT. Results A total of 2,084 patients with PBC were included in the analysis with 158 young patients. Compared to older adults, younger patients were more likely to be male (27.2% vs. 15.4%) and non-white (43.7% vs. 21.5%) but they were less likely to have obesity, diabetes, or hypertension (p

Antiphospholipid Syndrome And Renal Allograft Thrombosis

Renal allograft thrombosis is the most frequent and devastating complication in the early postrenal transplantation period. Several risk factors to develop graft thrombosis depending on donors and recipients are well known. Antiphospholipid syndrome (APS) is well recognized as an important cause of kidney injury, with specific clinical and histological features that may lead to renal injury caused by thrombosis at any location within the renal vasculature. There are 3 forms of APS, primary (the most common form), associated to other systemic autoimmune diseases (SAD-APS) and catastrophic. Nevertheless, patients with SAD-APS and renal failure only represent 2-5% in hemodialysis or transplantation. The presence of pretransplant antiphospholipid antibodies (APL) increases risk of graft thrombosis. A new form of APS based on IgA anti-Beta-2-Glycoprotein-I(B2GPI) antibodies, representing up to 30% of patients in ESRD and renal transplantation, is the main independent risk factor for graft thrombosis and early graft loss after renal transplantation. In addition, B2GP1 bound to IgA aB2GP1 immunocomplexes have been described as a marker to predict thrombosis after renal transplantation in patients with antiphospholipid antibodies. Anticoagulation remains the main treatment to prevent renal allograft thrombosis, although new preventive strategies are coming. Future studies may help to identify better therapeutic targets.

Favorable outcome of an exclusively posttransplant prophylactic strategy after heart transplantation in recipients with high immunological risk

Background Management of the increasing number of sensitised heart transplant candidates has become a recurrent issue. Rather than using pretransplant desensitisation therapies, we used a posttransplant prophylactic strategy. Our aim was to describe outcomes in transplant recipients with preformed donor-specific anti-HLA antibodies (pfDSA) managed with this strategy. Methods A posttransplant protocol was applied to patients transplanted with pfDSA, consisting of perioperative management of DSA (polyvalent immunoglobulins +/- perioperative plasmapheresis sessions, according to DSA level, as well as induction therapy) and systematic treatment of subsequent antibody-mediated rejection (ABMR), even when subclinical. We performed a retrospective analysis of this prospective protocol. The study included all consecutive first recipients of a noncombined heart transplant performed between 2009 and 2015 at our centre. The primary endpoint was all-cause mortality. Secondary endpoints included primary graft dysfunction, early posttransplant bleeding, rejection and cardiac allograft vasculopathy-free survival. Results A total of 523 patients were studied, including 88 (17%) and 194 (37%) transplanted with DSA mean fluorescence intensity (MFI) of 500–1000 and >1000, respectively. The median follow-up period was 4.06 years. Survival was not significantly different between groups. Rejection-free survival was worse in patients with pfDSA MFI >1000, evidenced by a fourfold increase in the risk of ABMR. The incidence of primary graft dysfunction and cardiac allograft vasculopathy-free survival did not significantly differ between groups. Perioperative plasmapheresis increased the risk for transfusion of packed red blood cells. Conclusions This exclusively posttransplant prophylactic strategy achieved favourable outcomes in heart transplant recipients with pfDSA.

Development of CDX-1140, an agonist CD40 antibody for cancer immunotherapy

Abstract

Limitations of immunotherapy include poorly functioning events early in the immune response cycle, such as efficient antigen presentation and T cell priming. CD40 signaling in dendritic cells leads to upregulation of cell surface costimulatory and MHC molecules and the generation of cytokines, which promotes effective priming of CD8⁺ effector T cells while minimizing T cell anergy and the generation of regulatory T cells. This naturally occurs through interaction with CD40 ligand (CD40L) expressed on CD4⁺ T-helper cells. CD40 signaling can also be achieved using specific antibodies, leading to several agonist CD40 antibodies entering clinical development. Our approach to select a CD40 agonist antibody was to define a balanced profile between sufficiently strong immune stimulation and the untoward effects of systemic immune activation. CDX-1140 is a human IgG2 antibody that activates DCs and B cells and drives NFkB stimulation in a CD40-expressing reporter cell line. These activities are Fc-independent and are maintained using an F(ab′)2 fragment of the antibody. CDX-1140 binds outside of the CD40L binding site, and addition of recombinant CD40L greatly enhances DC and B activation by CDX-1140, suggesting that CDX-1140 may act synergistically with naturally expressed CD40L. CDX-1140 also has both direct and immune-mediated anti-tumor activity in xenograft models. CDX-1140 does not promote cytokine production in whole blood assays and has good pharmacodynamic and safety profiles in cynomolgus macaques. These data support the potential of CDX-1140 as part of a cancer therapy regimen, and a phase 1 trial has recently commenced.
