Introduction: Drug rash with eosinophilia and systemic symptoms (DRESS) is a severe drug eruption with systemic involvement. Visceral manifestations consisting of fulminant hepatic failure, myocarditis, interstitial nephritis, pneumonitis and autoimmune hypothyroidism are known sequela. We report a case of DRESS syndrome post Bactrim (sulfamethoxazole and trimethoprim) therapy complicated by both myocarditis and autoimmune thyrotoxicosis.Case report: A p...

Retinopathy has been observed in around 25% of patients with type one and type two diabetes for 3–5 years. Diabetic retinopathy can cause poor vision and even blindness since high glucose has been evidenced to weaken retinal capillary leading to leakage of blood into the surrounding space. Therefore, the prevention, diagnosis and therapy of diabetes retinopathy are very important in diabetes patients. Here, we adopted a proteomics-based approach using 2D-DIGE and MALDI-TO...

Introduction: Although menstrual irregularity, including oligomenorrhea (OM), is associated with insulin resistance and hyperandrogenism, the relationship between the severity of menstrual infrequency and clinical phenotypes in young women with OM is unclear. We evaluated whether a longer menstrual cycle length is associated with less favorable metabolic features in young women.Methods/design: A total of 1296 young women (aged 15–39 years old) with ...

Atypical manifestations of hyperthyroidism include hematological, cardiovascular, dermatological manifestation. Especially single lineage abnormalities such as anemia (34%), leukopenia (5.8%), thrombocytopenia (3.3%) are reported, but pancytopenia is a rare presentation of hyperthyroidism. The suspected etiologic mechanisms include ineffective hematopoiesis, reduction in blood cell life span, autoimmune process, toxicity of thyroid hormone.We report a ca...

The class of endocrine disrupting chemicals (EDCs) is comprised of both naturally occurring and man-made compounds which are structurally similar or distinct to estrogen, and can interfere with the actions of an endogenous steroid hormone via estrogen receptors (ERs). Octylphenol (OP) is alkyl phenol chemical, which is considered to be a low-level endocrine disruptor owing to its tendency to mimic estrogen. It has been reported that triclosan can cause endocrine disruption and...

Endocrine disrupting chemicals (EDCs) have brougt the growing concern about the potential to interfere with the endocrine system and to cause health problems. Among EDCs, bisphenol A (BPA) and 1,1,1-trichloro-2,2-bis(4-methoxyphenol)-ethane (methoxychlor, MXC) can bind to estrogen receptors (ERs) and lead abnormality of ER depenent signaling pathways, resulting in human health problems such as dysfuction of reproduction and carcinogenesis. In this study, we investigated whethe...

Benzophenones are organic chemicals widely used as stabilizers to UV light irradiation in plastic surface coatings and food packaging. They have been known that their derivatives appear to have cytotoxic effects. 2-Hydroxy-4-methoxybenzophenone (Benzophenone-3, BP-3) and its metabolite, 2,4-dihydroxybenzophenone (Benzophenone-1, BP-1), are used mostly in the formulation of nail polishes, enamels, bath products, sunscreens and skin care products. In this study, the estrogenic e...

Glucagon-like peptide-1 (GLP-1) is an incretin hormone playing an important role in glucose-dependent insulin secretion and β-cell growth. However, GLP-1 is rapidly degraded by dipeptidyl peptidase IV (DPP-IV) in vivo. Many attempts have been made to develop long-acting GLP-1 analogs with chemical modification, amino acid substitution, and fusion protein technology. We previously showed that the N-terminal Ala- or Gly-extended GLP-1 and human immunoglobulin ...

We present a case of a 71-year-old Jamaican man who presented with a 4 weeks history of backache, lethargy, night sweats, decreased appetite, and weight loss. There was no significant medical history.Physical examination revealed tachypnoea, sinus tachycardia with evidence of short QT interval on the ECG, generalised lymphadenopathy with firm, rubbery glands up to 3×3 cm in diameter. Arterial blood gases were consistent with type 1 respiratory failu...

Background: Visceral fat is a key factor underlying type 2 diabetes. The amount and distribution of body fat is strongly influenced by sex steroids. Androgen receptors (ARs) are present in adipose tissue and are abundant in the detrimental visceral bed. Here, we sought to determine the contribution of the AR in adipose tissue to the pathophysiology of visceral obesity and type 2 diabetes.Methods: Male fat-specific AR-knockout (fARKO) mice (12 weeks; n...
