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...

Graves' disease (GD) accounts for a large proportion of pediatric hyperthyroidism, and the first-line treatment is antithyroid drug (ATD) therapy. Methimazole (MMI) is effective in most patients but is associated with significant adverse events (AEs). We reviewed the medical records of GD patients (n = 56) with onset age of <15 yr and investigated the relationship between MMI dose and AEs. The study population comprised 11 male and 45 female patients and the median age at diagnosis was 11 yr. All patients were initially treated with ATDs...

REVIEW
Mark Davies, Anurag Saxena, John C Kingswood
Tuberous sclerosis complex (TSC) is a genetic disorder characterised by highly variable comorbid dysfunction and subsequent morbidity. The mTOR inhibitor everolimus is indicated for the treatment of adult TSC patients with renal angiomyolipomas (AMLs) and for subependymal giant astrocytoma (SEGA) in both adults and children, based on data from the EXIST-1 and EXIST-2 trials. However, due to the historical predominance of everolimus in the oncology setting, some physicians who treat TSC patients may be unfamiliar with everolimus-associated adverse events (AEs) and appropriate management strategies...

Cutaneous adverse drug reactions are among the most common noninfectious rashes of childhood. Cutaneous adverse drug reactions are classified as morbilliform, urticarial, bullous, pustular, or psoriasiform. Atopic dermatitis is one of the most common inflammatory cutaneous eruptions, and is characterized by pruritus and flexural distribution. Emollients and topical corticosteroids are first-line therapies. Topical calcineurin inhibitors are second-line, steroid-sparing drugs for certain conditions, such as face and eyelid eczema...

Lindsey K Collins, M Shane Chapman, Joi B Carter, Faramarz H Samie
The immune checkpoint targeted agents, anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and anti-programed cell death 1 (PD-1) or anti-programmed death ligand 1 (PD-L1) inhibitors are frequently associated with cutaneous side effects that are often dose limiting and can lead to discontinuation of therapy. Ipilimumab, a CTLA-4 inhibitor, is most commonly associated with a morbilliform eruption on the trunk and extremities and pruritus. More severe cutaneous toxicities reported include toxic epidermal necrolysis and severe drug rash with eosinophila and systemic symptoms...

Nimodipine (NM) is the only FDA-approved drug for treating subarachnoid hemorrhage induced vasospasm. NM has poor oral bioavailability (5-13%) due to its low aqueous solubility, and extensive first pass metabolism. The objective of this study is to develop radiolabeled NM-loaded LPM and to test its ability prolong its circulation time, reduce its frequency of administration and eventually target it to the brain tissue. NM was radiolabeled with (99m)Tc by direct labeling method using sodium dithionite. Different reaction conditions that affect the radiolabeling yield were studied...

INTRODUCTION: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare but life-threatening reaction to drugs such as carbamazepine and allopurinol. The condition is characterized by skin rashes, fever, hematological disturbances, lymphadenopathy, and organ failure, most probably hepatic dysfunction. To date, only a few cases of valproate-induced DRESS syndrome have been reported. CASE PRESENTATION: We report on the case of a 60-year-old man who had been treated with valproic acid some time before being referred to Kowsar Hospital, Semnan, Iran in December 2015...

Enterovirus 71 (EV71) is a causative agent of hand-foot-mouth disease (HFMD). EV71 causes fever, rash, diarrhea, and, in some cases, acute encephalopathy/encephalitis, which can be fatal. No specific treatment is currently available for EV71 infection. Here, we conducted a cDNA library screen and identified acid β-glucosidase 1 (GBA1; also known as β-glucocerebrosidase) as an EV71 resistance factor. The anti-EV71 function of GBA1 was verified by gene transduction and knockdown experiments. Cerezyme, a molecular drug used to treat Gaucher's disease having recombinant human GBA1 as the active ingredient, protected against EV71 infection...

Drug-induced liver injury (DILI) is one of the most common adverse drug reactions. DILI is often accompanied by skin reactions, including rash and pruritus. However, it is still unknown whether DILI-associated genes such as S100 calcium-binding protein A and interleukin (IL)-1β are involved in drug-induced skin toxicity. In the present study, most of the tested hepatotoxic drugs such as pioglitazone and diclofenac induced DILI-associated genes in human and mouse keratinocytes. Keratinocytes of mice at higher risk for DILI exhibited an increased IL-1β basal expression...

Background Twenty-five years ago attorneys representing ailing women in class action litigation against silicone breast implant manufacturers made the procedural error of defining silicone-induced toxicity in the courtroom before it was properly studied in the exam room. This aberrant methodology perverted the proper research process, rendered verification of any real disease elusive, and cemented the groundwork for a repeat public health crisis potentially affecting two million women in the USA who possess new silicone gel devices inserted over the past 10 years...

Rumpel-Leede phenomenon (RLP), also known as acute capillary rupture syndrome (ACRS), is a rare occurrence where distal dermal capillaries rupture in response to a proximal compressive force, such as a blood pressure cuff or tourniquet. This phenomenon has been reported to occur in states of vascular fragility such as long-term steroid use, hypertension or diabetes mellitus. Here, we provide a report of RLP occurring secondary to tourniquet application in a 26-year-old woman with adult-onset Still's disease (AOSD) and a recent drug rash...
