Unlabelled: Obese individuals are frequently hyperleptinemic and insulin resistant. Chronic exercise is associated with improvements in plasma leptin level and insulin sensitivity; however, little is known about the acute effect of exercise on these parameters. The aim of this study was to evaluate the acute effect of aerobic exercise on plasma leptin and insulin sensitivity in obese women with stable caloric intake.

The aim of this study was to investigate the rate of incidental thyroid carcinoma in thyrotoxic patients managed with surgery in our institution.
Methods: Of the 375 thyrotoxic patients who had thyroid surgery between the years of 1997-2004, 70.
Because of the similarities between Cushing's syndrome and insulin resistance syndrome,cortisol metabolism in obesity has been investigated in numerous studies. Our study investigates serum glucose, insulin, and cortisol response to oral glucose stimulation in a group of obese and lean normotensive, normolipidemic, and glucose-tolerant premenopausal women. Twenty-one obese [body mass index (BMI) 37Z +/- 6.

Few cases of rhabdomyolysis associated with thyrotoxicosis have been reported. A patient who presented with delirium to the emergency department and was diagnosed with thyrotoxicosis and rhabdomyolysis is hereby presented.

Subjects And Design: Study population consisted of 89 obese women who had a body mass index > or = 30 kg/m2, were normotensive, and had normal glucose tolerance.
A 23-year-old female with Costello syndrome is presented. She had mental retardation, macrocephalia, "coarse" facial features, deep palmar and plantar creases, hyperkeratosis in palms and soles, hyperpigmentation, curly hair, and cutis laxa, which are among the diagnostic features of the syndrome, and a history of hyperprolactinemia since the age of 16. Her present complaint was weakness and widespread bone-pain.

Insulin resistance and hyperinsulinemia may have detrimental influences on the arterial wall. Statins (may also) inhibit insulin signal transferring in vascular smooth cell cultures.

The aim of this study was to investigate whether an increase in oxidative stress related to xanthine oxidoreductase occurs in diabetes. Liver, brain, heart, and kidney xanthine oxidase (XO), xanthine dehydrogenase (XDH), antioxidant enzymes (glutathione peroxidase, superoxide dismutase, catalase), and nitrite levels were measured in control and early and late diabetic rat models.

Although the exact pathogenic mechanisms of gallstone development are unknown, impaired gallbladder emptying has been suggested as a possible underlying mechanism. Our aim was to investigate this possibility by evaluating gallbladder motility and related factors in obese and nonobese women without gallstones.

Objective: Thyroid volume and thyroid function may vary in obese and nonobese women. It is not known whether weight loss could affect thyroid volume and function in obese subjects.
Patients And Methods: The study population consisted of 98 premenopausal euthyroid obese [body mass index (BMI) = 30 kg/m2] women (mean age 40.
Hypocalcemic cardiomyopathy due to hypoparathyroidism is a very rare condition which is usually refractory to conventional treatment for cardiac failure but which responds favorably to restoration of normocalcemia. A 55-year-old man and a 46-year-old woman with a history of postoperative hypoparathyroidism presented with symptoms of cardiac failure and hypocalcemia. A presumptive diagnosis of dilated cardiomyopathy was considered by echocardiography and endomyocardial biopsies were consistent with cardiomyopathy.

The aspiration cytology of the nodule was reported as follicular neoplasia and she underwent surgery. Frozen section was suspicious for medullary thyroid carcinoma and a total thyroidectomy was performed.
