A 47-year-old lady presented with a long history of resistant hypertension. Her GP referred her for further investigation to a cardiologist who found a smaller right kidney on ultrasound scan and an elevated rennin level. Renal artery MRA revealed right renal artery stenosis. On September 2008, she underwent right renal artery stenting and was advised to stop taking the antihypertensive medications (doxazosin and amlodipine). A week later she was admitted with headache, vomiti...

A 36-year-old gentleman presented to his GP 2 years ago with hypertension and was commenced on valsartan. In January 2008, he was noted to have mildly deranged LFT and abdominal ultrasound scan showed mild fatty liver infiltration and bilateral renal stones. He was referred to Urology for investigation of renal stones and a CT IVU showed multiple renal calculi, a 6×5×5 cm soft tissue enhancing lesion arising from the right adrenal gland and a 7 mm calcified density w...

Introduction: Prolactinomas, although considered benign, show various intensity of aggressiveness. Some remain constant for whole life period while some harbour initially with invasive extension to the parasellar area. We aimed to evaluate the effect of age and gender on the invasiveness of prolactinomas.Material-methods: One hundred and thirteen patients with prolactinoma were retrospectively evaluated. Magnetic resonance images were carefully examined ...

Myostatin is expressed predominantly in skeletal muscle and at significantly lower levels in adipose tissue. The loss of myostatin by gene disruption prevents an age-related increase in adipose tissue mass and partially attenuates the obese and diabetic phenotypes. Inhibition of myostatin signaling could be useful to prevent and/or treat obesity and diabetes. Male OLETF and LETO rats as non-diabetic controls were treated with or without ALA (100 mg/kg per day) and/or insulin (...

Introduction: Women with polycystic ovary syndrome (PCOS) have an increased prevalence of insulin resistance and related disorders. Endothelial dysfunction and chronic inflammation are early findings in the atherosclerotic process. Elevated serum levels of uric acid may reflect low-grade chronic inflammation. But there are controversial data whether increased the uric acid level in PCOS patients. This study was aimed to examine the relationship between uric acid, lipoprotein l...

In prolactin secreting pituitary adenomas, surgery markedly reduced with the efficacy of dopamine agonists in controlling prolactin hypersecretion and reducing tumor mass. Some surgeons, instead of necessity of almost life-long medical therapy, prefer and recommend surgery as a first line treatment with potentially high success rates especially in microprolactinomas. We evaluated our patients with prolactinoma operated mostly without any evidence of resistance or intolerance t...

Introduction: Hyalinizing trabecular adenomas (HTA) of the thyroid is an unusual disorder. HTA can be present as a thyroid nodule or incidental finding in a thyroidectomy specimen. Most behave as benign neoplasms, but their cytological features can be similar to those of papillary thyroid carcinoma.Case report: A 68 year old woman admitted to our institution with a solitary thyroid nodüle. Her serum free thyroxine (fT4), free triiodothyro...

Multiple myeloma is a hematologic malignancy characterized by osteolytic bone destruction which follows the increased osteoclastic resorption of bone that is not accompanied by increased bone formation. This can lead to bone pain, diffuse osteopenia, focal lytic lesions, pathologic fractures, spinal cord compression, and hypercalcemia, so it is evident that osteolytic bone disease is a major cause of morbidity and mortality in patients with multiple myeloma. Long-term monthly ...

Background: Sitagliptin, unlike the some major antihyperglycaemic drugs, is not associated with weight gain and has neutral effects on body weight. It is unclear whether sitagliptin treatment alters serum ghrelin levels in people with type 2 diabetes. The aim of the present study was to assess the effect of sitagliptin on serum ghrelin levels in patients with type 2 diabetes mellitus.Methods: Forty-four type 2 diabetic subjects were randomly assigned to ...
