Purpose: Forearm osteoporosis is a well-known complication of primary hyperparathyroidism (PHPT). However, measuring forearm bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) at the distal radius is often neglected in clinical practice despite the fact that osteoporosis at any site is a criterion indicating surgery. We aimed to...

Prolactinomas are the most common hormone-secreting pituitary adenomas. Prolactinomas account for nearly 30–40 percent of all the pituitary adenomas. Although it affects individuals over a wide age range, it is more common in 20– 40-year-old female patients, who are in their reproductive age. Prolactinomas may cause hypogonadism, menstrual cycle dy...

The coexistence of Cushing’s syndrome (CS) and pregnancy is uncommon due to the suppression of gonadotropin secretion in CS. Adrenocorticotropic hormone (ACTH) dependent CS in pregnancy is less frequent than adrenal causes. The diagnosis of CS during pregnancy is difficult since physiological changes in the hypothalamo-pituitary-adrenal axis may ca...

Distant metastasis may be the initial sign of differentiated thyroid carcinoma in rare cases. In this instance, the treatment approach is usually individualized. Unlike most other cancers, local treatment of the primary tumor (total thyroidectomy) is preferred as ablative surgery; so that radioactive iodine therapy should be more effective. Repeate...

Introduction: During pregnancy, a progressive increase in serum triglyceride (TG) and cholesterol levels is observed whereas TG levels mostly remain <300 mg/dl. In women with genetic forms of hypertriglyceridemia, pregnancy may cause extremely elevated TG levels leading to potentially life-threatening pancreatitis attacks and chylomicronemia syndr...
Article
Introduction: Isolated bone metastasis of endometrium carcinoma is rare; but if it occurs, pelvis and vertebrae are involved mostly. Co-existence of undiagnosed Paget’s disease in a patient with malignancy causes major problems in differential diagnosis. Case: A 77 year-old woman was admitted to our hospital with severe pelvic pain. She had been di...
