Introduction: Papillary thyroid carcinoma (PTC) is the commonest endocrine malignancy. Apart from genetic role in its pathogenesis, autoimmunity has been implicated in certain papers. But, reports have been tripolar ranging from causative, protective and neutral role of immunomodulation. In this context, we set out study the role of Pro- inflammatory cytokines in PTC in South Indian population.Material and methods: This prospective case-control study was...

Introduction: Taking a photograph of self alone or with a group called Selfie, has become modern day rage with spurt in smart phone technology. It has catapulted from a hobby in to psychiatric ailment, especially amongst teens and young adults. Though, it is considered as a psychiatric aberration keeping them aloof from social interactions, we observed an inadvertent advantage in this habit. In this context, we present some intriguing findings through this study.<p class="...

Case history: A 38-year-old woman presented with blepharospasm, cramping of the hands, and paraesthesia primarily affecting the face and hands. Symptoms had been present for 10 years but had been progressive over the previous 12 months. Symptoms were consistent with neuromuscular instability. Hypocalcaemia and elevated Parathyroid hormone (PTH) were confirmed. Past medical history was notable for anorexia nervosa in remission. Family history was non-contributary. Hypocalcaemia...

Introduction: Hypopituitarism is the most frequent side effect of radiation or gamma knife radiosurgery (GKRS) for sellar diseases. There is a paucity of literature on the impact of GKRS on the hormonal profile of non-sellar diseases, even though the impact of radiation on pituitary hormones has been widely explored in sellar as well as non-sellar pathologies. In patients receiving treatment for non-sellar diseases, we assessed the effect of GKRS on hormonal p...

Background: No predictive biomarkers for NFPT recurrence have been identified, apart from Ki67. We employed high-throughput mass spectrometry-based analyses to examine the phosphorylation pattern of different subsets of NFPTs. Methods: Based on histopathological, radiological and surgical features, NFPTs were sub-grouped into three groups: non-invasive (n = 15), invasive (n = 10) and recurrent (n = 5) subtypes. Invasiveness was...

A 25 year old Afghan male presented with a 4 day history of worsening left-sided loin pain. He had a past history of deafness since birth, speech problems and development delay. Bilateral renal calculi and widespread multiple well defined lytic lesions (likely brown tumours) were seen on CT-KUB. The corrected calcium was 3.21 mmols/l, PTH 80 pmol/l, Vitamin D 25 nmol/l, phosphate 0.49 mmols/l, ALP 960 IU/l and fractional calcium excretion was 0.16. His skull X Ray/OPG, done du...

Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder characterised by the combined occurrence of parathyroid tumours, and neuroendocrine tumours (NETs) of the pituitary and pancreas. MEN1 is caused by mutations of the tumour suppressor gene MEN1, and MEN1 germline mutations are found in >75% of MEN1 patients. The remaining 25% of patients may have mutations involving as yet unidentified gene...

G-protein subunit α-11 (Gα11), which is encoded by GNA11, plays a major role in calcium homeostasis by regulating parathyroid hormone (PTH) secretion, and germline loss-of-function mutations cause familial hypocalciuric hypercalcaemia type 2 (FHH2). Since Gα11 is ubiquitously expressed, we investigated whether FHH2 is associated with additional non-calcitropic phenotypes by analysing mice harbouring a homozygous germline deletion o...

Background: No predictive biomarkers have been identified for clinically nonfunctioning pituitary tumour (NFPT) recurrence, with Ki67 being controversial. We employed quantitative mass spectrometry-based analyses to examine the differential expression of proteins in NFPTs.Methods: NFPTs were sub-grouped: non-invasive/non-recurrent group (NI/NR-G, n=5), invasive group (I-G, n=10) and recurrent group (R-G, n=5). Invasiveness was ...
