Introduction: SOCS2 is an important negative regulator of post-natal growth, as demonstrated by the SOCS2 null overgrowth phenotype. We have used SOCS2−/− mice, alongside chondrocytes overexpressing SOCS2, to investigate the mode of action of SOCS2 at the epiphysis. SOCS2 maybe involved in growth retardation associated with chronic inflammatory disorders, therefore we studied LPS induced growth retardation in wild type (WT) and SOCS2−/−<...

Introduction: The hypothalamic kiss1/kisspeptin system is pivotal in controlling fertility. However, kiss1 transcripts were also quantified in rat fat, where expression was regulated by oestradiol (Brown et al. 2008) and by dihydrotestosterone (DHT; Brown et al. 2009). In human fat, microarray analysis revealed abnormal, multiple gene expression in obese PCOS patients (Corton et al. 2007). In the present experiments we used a rat model (Manne...

Introduction: Plasma cell neoplasms include a variety of clinicopathologic entities including; multiple myeloma, solitary plasmacytoma of bone and extramedullary plasmacytoma. Plasma cell neoplasms of the pituitary area are very rare, with only 19 cases in the literature. We report a rare case of multiple myeloma presenting with parasellar mass.Case: A 44-year-old lady was admitted with sudden onset of diplopia and blurring of vision. She also mentioned ...

Introduction: Dilated cardiomyopathy is an uncommon, but well recognized, manifestation of thyrotoxicosis. However, hyperthyroidism presenting with dilated cardiomyopathy is very rare. We describe an unusual case of dilated cardiomyopathy as the initial manifestation of Graves’ hyperthyroidism.Case: A 61-year-old man of Malaysian origin, with no significant past medical history, was admitted with two month history of worsening shortness of breath, o...

A 59-year-old lady was admitted with lethargy and dehydration in October 1998 and investigations confirmed primary hyperparathyroidism with corrected calcium 4.49 mmol/l (N: 2.1–2.6). After fluid resuscitation, she underwent parathyroidectomy and biopsy revealed parathyroid hyperplasia. Post-operatively, her calcium remained normal until November 2000 when her corrected calcium was 3.05 mmol/l with PTH 311 ng/l (N: 12–65). Sestamibi scan failed to local...

Fat-derived adipokine genes that modulate metabolic and inflammatory responses, such as resistin (rstn) and fasting-induced adipose factor (fiaf), are also expressed in mouse brain and pituitary gland. We, and others, reported that central fiaf and rstn mRNA levels were increased following a brain injury-induced inflammatory response, and central injection of resistin reduced food intake and increased hepatic glucose production. Since LPS-induced en...

An 18-year old male presented with galactorrhoaea and obesity. PRL measured 16,630 mU/l, FSH 6.0 U/l, LH 5.0 U/l, testosterone 8.6 nmol/l, SHBG 15.0 nmol/l, IGF-1 22.0 nmol/l and TSH 1.39 mU/l. Several 24-hour urinary free cortisol estimations excluded hypercortisolism. Short synacthen test confirmed an intact HPA axis. Visual fields were full. Pituitary-MRI revealed a large adenoma extending into the right cavernous sinus without suprasellar extension. PRL started declining u...

Background: Polycystic ovary syndrome (PCOS) occurs in women of reproductive age and is characterized by hyperandrogenism, polycystic ovaries, oligomenorrhea or amenorrhea. Estimated prevalence is at least 6.5%. Women having PCOS tend to be overweight or obese. In addition to endocrine, metabolic and gynecological, features of PCOS, a number of psychological problems add up which affect quality of life and psychological well-being in women with PCOS.Mate...

We report a 77 year old male who presented to the respiratory clinic with episodes of periodic sweating. These episodes were associated nausea. They came on with exercise and always occurred before meals. The resolving factor noted by the patient was food intake and no features suggestive of reactive hypoglycaemia were noted. His past medical history was significant for hypertension, mild bronchiectasis, mild to moderate obstructive sleep apnea requiring CPAP therapy and ische...

Aim To describe the early outcomes of carcinoid patients undergoing surgical heart valve replacement.Methods In a retrospective study, records of patients with symptomatic carcinoid heart disease referred for valve surgery between 2012 and 2021 were reviewed. The perioperative and early postoperative outcomes were analyzed.Results Thirteen patients, with a mean age of 64 years (range 55-79 years) underwent cardiac surgery for carci...
