Rickettsia slovaca, a spotted fever group rickettsial pathogen, causes a syndrome consisting of scalp eschar and neck lymphadenopathy following tick bites. We analyzed the histologic skin reaction in the eschar, showing a prominent eosinophilic infiltration, as well as the presence of B lymphocytes and CD4- and CD8-positive T cells. Examination of the serum cytokine responses over time demonstrated an initial proinflammatory cytokine elevation followed by normalization.

Cannabidiol (CBD) has gained much attention in the past several years for its therapeutic potential in the treatment of drug-resistant epilepsy, such as Dravet Syndrome. While CBD has shown anecdotal efficacy in reducing seizure frequency, little is known regarding the potential adverse side-effects of CBD on physiology, development, organogenesis, or behavior. The goal of this project is to compare the relative morphological, behavioral, and gene expression phenotypes resulting after a developmental exposure to Δ9-tetrahydrocannabinol (THC) or CBD...

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is one of the most devastating of adverse drug reactions (ADRs) and was, until recently, essentially unpredictable. With the discovery of several risk alleles for drug-induced SJS/TEN and the demonstration of effectiveness of screening in reducing incidence, the stage is set for implementation of preventive strategies in populations at risk. Yet much remains to be learned about this potentially fatal complication of commonly used drugs.

Fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorders (FASD) result from intrauterine exposure to alcohol and are the most common nonheritable causes of intellectual disability. The percentage of women who drink or binge drink during pregnancy has increased since 2012. FAS is commonly missed or misdiagnosed, preventing affected children from receiving needed services in a timely fashion. Diagnosis is based on the presence of the following clinical features, all of which must be present: prenatal and/or postnatal growth retardation, facial dysmorphology, central nervous system dysfunction, and neurobehavioral disabilities...

Many natural products present in our diet, including flavonoids, can prevent the progression of cancer and other diseases. Resveratrol, a natural polyphenol present in various fruits and vegetables, plays an important role as a therapeutic and chemopreventive agent used in the treatment of various illnesses. It exhibits effects against different types of cancer through different pathways. It additionally exerts antidiabetic, anti-inflammatory, and anti-oxidant effects in a variety of cell types. Furthermore, the cardiovascular protective capacities of resveratrol are associated with multiple molecular targets and may lead to the development of novel therapeutic strategies for atherosclerosis, ischemia/reperfusion, metabolic syndrome, and heart failure...

Children with Down syndrome (DS) have wide range of respiratory problems. Although underlying abnormalities in the respiratory system are important causes of morbidity and mortality in children with DS, particularly in the young, abnormalities in other organ systems may also impact respiratory function. A comprehensive evaluation of the child with DS and respiratory disease may prevent short-term morbidity and mortality, and reduce the incidence of complications in the long term. This review provides an overview of the various causes of respiratory disease, and insight into some of the newer therapies available to treat obstructive sleep apnea, in this population...

Therapy-related myelodysplastic syndrome (t-MDS) is a long-term complication of cancer treatment for patients receiving cytotoxic therapy, characterized by high-risk genetics and poor outcomes. Allogeneic hematopoietic cell transplantation represents the only curative modality for t-MDS, but the prognostic impact of pre-transplant genetics and clinical features has not yet been fully characterized. We report here the genetic, clinical characteristics and outcomes of a relatively large cohort of t-MDS patients (n=67) who received alloHCT compared to similarly treated patients with de novo MDS (n=199)...

There are multiple etiologies for fetal dilated bowel loops on ultrasonography (US), and we present a unique case of male siblings with a forkhead box P3 (FOXP3) mutation. Both children presented with fetal bowel anomalies on prenatal US. Family histories of cystic fibrosis and immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome were reported. Amniocentesis in both pregnancies identified a normal male karyotype and the familial mutation associated with IPEX syndrome. IPEX syndrome is one of a group of conditions known as congenital diarrhea disorders...
