Atypical fibroxanthoma (AFX), is a rare type of skin cancer affecting older individuals with sun damaged skin. Since there is limited genomic information about AFX, our study seeks to improve the understanding of AFX through whole-exome and RNA sequencing of 8 matched tumor-normal samples. AFX is a highly mutated malignancy with recurrent mutations in a number of genes, including COL11A1, ERBB4, CSMD3, and FAT1. The majority of mutations identified were UV signature (C>T in dipyrimidines). We observed deletion of chromosomal segments on chr9p and chr13q, including tumor suppressor genes such as KANK1 and CDKN2A, but no gene fusions were found...

INTRODUCTION: Dermatological complaints have been estimated to represent up to 5-10% of all the visits to emergency departments. The main objective of our study was to determine how affected is the Health related Quality of Life (HRQL) in a series of patients attending an emergency department due to skin symptoms. PATIENTS AND METHODS: A prospective study during one month (July 2016) was conducted in a hospital with full-time on-call dermatologists. The Short-Form SF-12v2 Health Survey and the Dermatology Life Quality Index (DLQI) were offered to all the patients over 18 years old attending the emergency department with cutaneous complaints...

BACKGROUND: Higher body mass index (BMI) and obesity is common among youth with bipolar disorder (BD) and is associated with greater psychiatric illness severity, including suicidality. Obesity has been associated with frontal, temporal and subcortical volumetric reductions in adults with BD. We examined the neurostructural correlates of BMI in adolescents early in their course of BD. METHODS: We processed T1-weighted images of adolescents with BD and psychiatrically healthy controls using FreeSurfer to derive a priori region of interest (ROI) volumes/cortical thickness for the frontal lobe (FL), prefrontal cortex (PFC) and orbitofrontal cortex (OFC) as well as volumes for the amygdala and hippocampus...

RATIONALE: Quantification of type-2 inflammation provided a molecular basis for heterogeneity in asthma. Non-type-2 pathways that contribute to asthma pathogenesis are not well understood. OBJECTIVES: To identify dysregulated pathways beyond type-2 inflammation. METHODS: We applied RNA sequencing to airway epithelial brushings obtained from stable mild asthmatics not on corticosteroids (n=19) and healthy controls (n=16). Sequencing reads were mapped to human and viral genomes...

PURPOSE: Anonymised, routinely-collected healthcare data is increasingly being used for epilepsy research. We validated algorithms using general practitioner (GP) primary healthcare records to identify people with epilepsy from anonymised healthcare data within the Secure Anonymised Information Linkage (SAIL) databank in Wales, UK. METHOD: A reference population of 150 people with definite epilepsy and 150 people without epilepsy was ascertained from hospital records and linked to records contained within SAIL (containing GP records for 2...

Asthma is characterized by episodic, reversible airflow obstruction associated with variable levels of inflammation. Over the past several decades, there has been an increasing appreciation that the clinical presentation of asthma comprises a diverse set of underlying pathologies. Rather than being viewed as a single disease entity, asthma is now thought of as a clinical syndrome with the involvement of multiple pathological mechanisms. While it is appreciated that eosinophilia is present in only a subset of patients, it remains a key feature of asthma and other eosinophilic disorders such as atopic dermatitis, eosinophilic esophagitis, and chronic rhinosinusitis with nasal polyps...

BACKGROUND: The Organ Procurement Transplant Network (OPTN) registry collects data on posttransplant malignancies in solid organ transplant recipients. Complete and accurate registry data on skin cancer is critical for research on epidemiology and interventions. OBJECTIVE: The study goal was to determine the validity of Organ Procurement Transplant Network skin cancer data. METHODS: This cohort study compared reporting of posttransplant squamous cell carcinoma (SCC) and malignant melanoma (MM) in OPTN to medical-record review-derived data from the Transplant Skin Cancer Network (TSCN) database...

Placodes are discrete thickenings of the vertebrate cranial ectoderm that generate morpho-functionally distinct structures, such as the adenohypophysis, olfactory epithelium and lens. All placodes arise from a horseshoe-shaped preplacodal ectoderm in which the precursors of individual placodes are intermingled. However, fate-map studies indicated that cells positioned at the preplacodal midline give rise to only the adenohypophyseal placode, suggesting a unique organization of these precursors within the preplacode...

Long-term iatrogenic immunosuppression increases the risk of cutaneous malignancies in organ transplant recipients (OTRs), particularly the keratinocyte cancers basal cell carcinoma and cutaneous squamous cell carcinoma (cSCC). cSCC is the most common malignancy in OTRs, with the risk increased to over 65-fold in transplanted patients relative to the general population. There have been very few risk prediction tools developed for accurate determination of the risk of developing keratinocyte cancers in the OTR population...

PURPOSE: To present the performance and safety of the Treovance stent graft for endovascular aortic aneurysm repair in a "real-world" patient cohort. METHODS: Patients from 2 centers, deemed unfit for open repair, were electively treated with the Treovance endograft. Clinical preoperative, operative, and up to 1-year postoperative follow-up data of patients were retrospectively analyzed. RESULTS: This study included 46 patients with abdominal aortic aneurysm (44 male), mean age of 78 years ± 8 standard deviation (SD; range: 58-93 years)...

AIM: The aim of this study was to assess the match-to-match variability obtained using GPS devices, collected during official games in professional soccer players. METHODS: GPS-derived data from nineteen elite soccer players were collected over two consecutive seasons. Time-motion data for players with more than five full-match were analyzed (n=202). Total distance covered (TD), TD >13-18 km/h, TD >18-21 km/h, TD >21 km/h, number of acceleration >2.5-4 m...

BACKGROUND: Vismodegib is a first-in-class agent targeting the hedgehog signaling pathway for treatment of patients with locally advanced basal cell carcinoma (BCC) and metastatic BCC. There have been concerns about the development of squamous cell carcinoma (SCC) in patients treated with this drug. OBJECTIVE: We sought to determine whether treatment with vismodegib is associated with an increase in the risk of cutaneous SCC. METHODS: In this retrospective cohort study, patients treated with vismodegib as part of phase I and II clinical studies were compared with participants from the University of California, San Francisco, Nonmelanoma Skin Cancer Cohort who received standard therapy for primary BCC...

BACKGROUND: Recent researches in the field of genetics have extended our knowledge through the discovery of genetic factors associated with autoimmune diseases (AID). Genetics by itself, however, cannot elucidate all the uncertainties encountered in the etiopathology of AID. On the other hand, incomplete harmony in the prevalence of AID in identical twins suggests that non-genetic factors may play an important role in determining the disease susceptibility. Besides, epigenetics, which is defined by changes in gene expression without a corresponding change in the DNA sequences, has come in to provide new awareness in the disease etiopathology by bridging the genetic and epigenetic factors...

BACKGROUND: A named patient program (NPP) was designed to provide patients with advanced soft-tissue sarcoma (aSTS) access to pazopanib, a multitargeted tyrosine kinase inhibitor. The SPIRE study was a retrospective chart review of participating patients. PATIENTS AND METHODS: Eligibility criteria for the NPP and SPIRE mirrored those of the pivotal phase-III study, PALETTE, which compared pazopanib with placebo in patients ≥18 years with aSTS and whose disease had progressed during or following prior chemotherapy or were otherwise unsuitable for chemotherapy...
