Introduction: The Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) is an X-linked condition characterised by reduced renal water clearance and hyponatraemia resulting from gain of function mutations in the type 2 Vasopressin (AVP) receptor (AVPR2). Female carriers were thought not to express a phenotype. We describe a kindred with NSIAD, highlighting molecular and physiological characteristics that extend understanding of this condition and of AVP production.<p c...

Patients with acromegaly treated with medical therapy intermittently discontinue therapy to allow assessment of underlying disease activity. This is particularly so in patients treated with pituitary irradiation. Typical 'washout' times include 5 weeks for bromocriptine and 2 weeks for short-acting sc octreotide; longer periods are required for cabergoline and slow-release somatostatin analogues. Pegvisomant is a novel medical therapy for acromegaly that functions as a GH rece...

High protein diets are effective at promoting weight loss and stimulating the secretion of pancreatic hormones. Understanding the mechanisms underlying these effects may highlight new potential therapeutic targets. The calcium sensing receptor (CaSR) is stimulated by calcium and plays a critical role in calcium homeostasis. However, it is also found in many tissues unrelated to calcium regulation. CaSR activity can be modulated by aromatic amino acids, most potently by ...
