Stevens-Johnson syndrome/toxic epidermal necrolysis after initiation of carbamazepine in a HLA-B*15:02 gene carrier - screening in risk patients is recommended A 32-year-old woman, adopted from Indonesia, developed Stevens-Johnsons syndrome (SJS)/toxic epidermal necrolysis (TEN) after initiating carbamazepine treatment for epilepsy. SJS and TEN are rare but life-threatening adverse effects of carbamazepine, with a 72-100% risk of occurrence in patients carrying the HLA-B*15:02 allele. The HLA-B*15:02 allele is common in several Asian groups but less prevalent in European populations...

Nanoparticles of Ti3O5 have been reported to show a permanent photoinduced phase transition at room temperature. This suggests that light-induced phase transformations of Ti3O5 nanoparticles may be promising for technological applications. Here we report a photoinduced semiconductor-to-metal phase transition from beta-Ti3O5 to lambda-Ti3O5 nanoparticles at room temperature observed directly by time-resolved x-ray powder diffraction in a pump-probe setup. The results show a partial structural change, limited by differences between pumped and probed volumes, that persists a few microseconds after excitation...

INTRODUCTION: Most patient safety research has focused on specialist-care settings where there is an appreciation of the frequency and causes of medical errors, and the resulting burden of adverse events. There have, however, been few large-scale robust studies that have investigated the extent and severity of avoidable harm in primary care. To address this, we will conduct a 12-month retrospective cross-sectional study involving case note review of primary care patients. METHODS AND ANALYSIS: We will conduct electronic searches of general practice (GP) clinical computer systems to identify patients with avoidable significant harm...

BACKGROUND: Thyroid carcinoma, which is rare in pediatric patients (age 0-18 years) but more common in adolescent and young adult (AYA) patients (age 15-39 years), carries the potential for morbidity and mortality. METHODS: Hybrid-capture-based comprehensive genomic profiling (CGP) was performed prospectively on 512 consecutively submitted thyroid carcinomas, including 58 from pediatric and AYA (PAYA) patients, to identify genomic alterations (GAs), including base substitutions, insertions/deletions, copy number alterations, and rearrangements...

Stevens-Johnson syndrome is one of the few dermatological emergencies in clinical practice. The syndrome is often secondary to the usage of drugs, of which allopurinol, penicillins, sulfa drugs, ibuprofen, sodium valproate, phenytoin, lamotrigine and carbamazepine are commonly implicated. Agranulocytosis is the existence of a clinically significant reduction in neutrophil count. This condition is a serious threat to the patient, as he/she is at a greater risk of contracting bacterial or fungal infections, which may prove to be fatal...

Nuts have been identified as a vector for salmonellosis. The objective of this project was to estimate the prevalence and contamination level of Salmonella in raw tree nuts (cashews, pecans, hazelnuts, macadamia nuts, pine nuts, and walnuts) at retail markets in the United States. A total of 3,656 samples of six types of tree nuts were collected from different types of retail stores and markets nationwide between October 2014 and October 2015. These samples were analyzed using a modified version of the Salmonella culture method from the U...

Marine spatial planning (MSP) is increasingly utilized to sustainably manage ocean uses. Marine protected areas (MPAs), a form of spatial management in which parts of the ocean are regulated to fishing, are now a common tool in MSP for conserving marine biodiversity and managing fisheries. However, the use of MPAs in MSP often neglects, or simplifies, the redistribution of fishing and non-fishing activities inside and outside of MPAs following their implementation. This redistribution of effort can have important implications for effective MSP...

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent genetic cause of renal failure. Here we identify miR-17 as a target for the treatment of ADPKD. We report that miR-17 is induced in kidney cysts of mouse and human ADPKD. Genetic deletion of the miR-17∼92 cluster inhibits cyst proliferation and PKD progression in four orthologous, including two long-lived, mouse models of ADPKD. Anti-miR-17 treatment attenuates cyst growth in short-term and long-term PKD mouse models. miR-17 inhibition also suppresses proliferation and cyst growth of primary ADPKD cysts cultures derived from multiple human donors...

BACKGROUND: HLA-B*15:02 is a known biomarker for carbamazepine (CBZ)-induced Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) in some ethnic populations. The US FDA recommends B*15:02 screening for Asian and other populations with a high prevalence of B*15:02 prior to treatment with CBZ to prevent drug-related SJS/TEN. MATERIALS AND METHODS: A total of 1607 blood samples were collected from volunteer blood donors who were ethnic minorities living in the Yunnan province of southwestern China, including 153 Yi, 193 Naxi, 167 Miao, 156 Lisu, 166 Derung, 211 Bai, 184 Hani, 198 Dai, and 179 Zhuang...

BACKGROUND: Severe cutaneous adverse reactions (SCARs) are prominent in pharmacovigilance (PhV). They have some commonalities such as nonimmediate nature and T-cell mediation and rare overlap syndromes have been documented, most commonly involving acute generalized exanthematous pustulosis (AGEP) and drug rash with eosinophilia and systemic symptoms (DRESS), and DRESS and toxic epidermal necrolysis (TEN). However, they display diverse clinical phenotypes and variations in specific T-cell immune response profiles, plus some specific genotype-phenotype associations...

REVIEW
Vincent Lai Ming Yip, Munir Pirmohamed
Carbamazepine (CBZ) is an effective anticonvulsant that can sometimes cause hypersensitivity reactions that vary in frequency and severity. Strong associations have been reported between specific human leukocyte antigen (HLA) alleles and susceptibility to CBZ hypersensitivity reactions. Screening for HLA-B*15:02 is mandated in patients from South East Asia because of a strong association with Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). HLA-A*31:01 predisposes to multiple phenotypes of CBZ hypersensitivity including maculopapular exanthema, hypersensitivity syndrome, and SJS/TEN in a range of populations including Europeans, Japanese, South Koreans and Han Chinese, although the effect size varies between the different phenotypes and populations...

A small number of proteins form a conserved pathway of centriole duplication. In humans and flies, the binding of Plk4/Sak to STIL/Ana2 initiates daughter centriole assembly. In humans, this interaction is mediated by an interaction between the Polo-Box-3 (PB3) domain of Plk4 and the coiled-coil domain of STIL (HsCCD). We showed previously that the Drosophila Ana2 coiled-coil domain (DmCCD) is essential for centriole assembly, but it forms a tight parallel tetramer in vitro that likely precludes an interaction with PB3...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening mucocutaneous diseases. SJS/TEN mostly manifest as a reaction to new drug use, but little is known about their incidence and epidemiology. We conducted a large observational study on the epidemiology of SJS/TEN using data from the UK-based Clinical Practice Research Datalink. Among 551 validated SJS/TEN cases, we calculated an incidence rate of 5.76 SJS/TEN cases/million person-years between 1995 and 2013, which was consistent throughout the study period, and was highest in patients aged 1-10 years and ≥80 years...

OBJECTIVE: Painful chronic pancreatitis is often associated with main duct obstruction due to stones. Approaches to management are challenging, including surgery, extracorporeal shock wave lithotripsy, or endoscopic approaches. Here, we report our experience of pancreatoscopy + electrohydraulic lithotripsy (EHL) for pancreatic duct (PD) stones using SpyGlass. METHODS: We retrospectively audited the use of SpyGlass (Legacy and DS) + EHL. Indication, procedural details, and clinical outcomes were assessed...

Conventional immunoassays rely on antibodies that provide high affinity, specificity and selectivity against a target analyte. However, the use of antibodies for the detection of small-sized, non-immunogenic targets, such as pharmaceuticals and environmental contaminants presents a number of challenges. Recent advances in protein engineering have led to the emergence of antibody mimetics that offer the high affinity and specificity associated with antibodies but with reduced batch-to-batch variability, high stability and in vitro selection to ensure rapid discovery of binders against a wide range of targets...
