BACKGROUND: Ultrasound guided fine needle aspiration biopsy with cytologic analysis is an initial step in diagnostic of thyroid nodules. Unfortunately, up to 30% of biopsies are indeterminate and diagnostic surgery is required. The aim of this study was to estimate the diagnostic value of BRAF V600E mutation status combined with cytomorphological features for diagnosis of papillary thyroid cancer (PTC) in cytologically indeterminate thyroid nodules. METHODS: A prospective study analyzed patients who had ultrasound suspicious thyroid nodules, underwent fine needle aspiration and cytological examination, and were classified according to the Bethesda system...

Amiodarone is one of the most commonly prescribed antiarrhythmic agents in clinical practice owing to its efficacy, even with high toxicity profile. The high iodine content and the prolonged biological half-life of the drug can result in thyroid dysfunction in a high proportion of patients treated with amiodarone even after cessation of amiodarone. Both hypothyroidism and hyperthyroidism are common side effects that mandate regular monitoring of patients with thyroid function tests. Amiodarone-induced hypothyroidism (AIH) is diagnosed and managed in the same way as a usual case of hypothyroidism...

Hypertension occurs in 7-10% of pregnant women. Despite the continuous development of medicine, it is still an important risk factor for perinatal mortality of both mothers and fetuses. Pregnant women with hypertension are at greater risk of complications such as: placental abruption, cerebral and cardiac incidents, multiorgan failure, and disseminated intravascular coagulation. The aim of this review was to discuss multilevel disorders of the renin-angiotensin-aldosterone system in the etiopathogenesis of pregnancy-induced hypertension...

BACKGROUND: A large proportion of subjects with type 2 diabetes mellitus (T2DM) in India are non-obese. Asian-Indian subjects with diabetes have been shown to have low vitamin D levels. Whether low vitamin D levels and T2DM in Asian-Indians is attributable to the associated obesity as in caucasians is unclear. Hence we studied the association of vitamin D levels and T2DM in Asian-Indians with or without obesity. METHODS: Total of 213 subjects were recruited in four groups, group 1-Non-obese diabetic, group 2-Non-obese non-diabetic, group 3-Obese diabetic and group 4-Obese non-diabetic...

BACKGROUND: Luteinizing hormone (LH) is a useful parameter in diagnosing precocious puberty. The pubertal response of serum LH to a GnRH stimulation test is varied, and clinical symptoms of precocious puberty are sometimes disproportionate with serum LH concentrations. Many patients present in a state of precocious puberty that advances rapidly, but the post-GnRH peak LH remains prepubertal. LH receptor mutations are suspected of involvement in the non-classic type of central precocious puberty (CPP)...

The receptor for advanced glycation end-products (RAGE) is a multi-ligand receptor which belongs to the pattern recognition receptor family and can bind to various ligands such as advanced glycation end-products (AGEs), members of the S100 protein family, glycosaminoglycans, amyloid β peptides, high-mobility group box-1 (HMGB1) and nucleic acids through its extracellular domain. The RAGE-ligand interaction leads to the activation of MAP kinase and NF-kB signaling pathways. Further ligand-induced up-regulation of RAGE is involved in various patho-physiological situations including late diabetic complications, Alzheimer disease and several other neurodegenerative diseases...
