Background: The aim of this study was to explore if evaluation of lipid risk factors like Lipoprotein(a) (Lp(a)) and conventional lipid profile parameters can be a efficient predictor of the cardiovascular risk in the patients of Diabetes.Methods: Sixty individuals with angiographically proven premature CAD and 30 healthy individuals matched for age and sex were studied a tertiary health care centre, New Delhi, India, over a period of 18 months. CAD pati...

Background: Premature pubic hair development, with or without manifestations of androgen production, is a common clinical presentation. Premature adrenarche (PA) needs to be differentially diagnosed from congenital adrenal hyperplasia (CAH) and may be associated with early development of puberty.Aim: To study the characteristics at presentation, endocrine profile and outcome of patients who presented with premature pubic hair development. We studied retr...

Thyroid hormone (T3) is essential for skeletal development and maintenance of bone mineralisation. T3 actions are mediated by two receptors, TRalpha and TRbeta. Mutations in TRbeta cause autosomal dominant resistance to thyroid hormone (RTH) due to dominant negative activity of the mutant receptor. Short stature and abnormal skeletal development are prominent features of RTH, whereas TRalpha mutations have not been described and are postulated to result in no phenotype or to b...

Thyroid hormone (T3) receptor beta (TRbeta) mutations cause resistance to thyroid hormones (RTH), characterised by decreased tissue sensitivity to T3. The TRbetaPV mutation (C-insertion at codon 448 leads to a frameshift of the carboxy-terminal 14 amino acids) was derived from a patient with severe RTH and generates a receptor lacking T3-binding and transactivation activities. Heterozygous mutant mice have a mildly impaired pituitary-thyroid axis; severe RTH and limb shortenin...

Background and aim: Achondroplasia (ACH) is one of the commonest skeletal dysplasias affecting 1:15 000–1:40 000 live births. The average attained adult height is 131±5.6 cm for men and 124±5.9 cm for women. Previous studies have shown that the use of rhGH may result in transient increase in the growth rate, but there have been no long-term data regarding adult height. We aimed to study a cohort of patients with ACH and other skeletal dysplasias who have been tr...

Background: Military personnel on operational deployment commonly lose weight despite the adequate supply of rations. Moderate weight loss (~5% body mass) occurred during the initial phase of a 6-month deployment to Afghanistan without affecting physical fitness. Reasons for this weight loss are presently unknown. We sought to establish whether changes in appetite regulatory hormones contribute to the observed weight loss.Methods: Body mass and body comp...

Background: Military training has been associated with changes in the hypothalamic–pituitary–testicular axis that are consistent with central hypogonadism (fall in testosterone, LH and FSH concentrations). The effects on the hypothalamic–pituitary–testicular axis of deployment to a combat zone are not known. The aim of this study was to clarify this situation.Methods: Military personnel were investigated pre-deployment (Pre-) and foll...

Background and Aim: The development of the pituitary gland is closely linked to this of the eyes and forebrain, as they all originate from the same embryonic origin, the anterior neural ridge. The constellation of symptoms leading to septo-optic dysplasia (SOD) is well established; other ophthalmic signs may be under-reported. The aim of the study was to define if patients with hypopituitarism present with eye abnormalities, which are distinct from optic nerve hypoplasia (ONH)...

Background: The altered DNA methylation of certain genes in Pituitary Neuroendocrine Tumors (PitNETs) are well known. However little information is available regarding global methylation changes and the process of demethylation in these tumors. In addition, influencing global methylation-demethylation could be a potential new therapeutic option especially in clinically non-functional PitNETs.Material and Methods: Overall, 44 fresh frozen pituitary adenom...
