Background: Prolactin secreting pituitary adenomas (prolactinomas) is the most common pituitary adenoma. The magnitude of prolactin secretion in prolactinomas is usually proportionate to the tumor’s size. Invasive giant prolactinoma is a large prolactinoma (>4 cm in dimension) presenting with serum prolactin levels of >1000 ng/ml and mass related clinical symptoms. Giant prolactinoma is rare and usually presents in men.Case report: A 52-year...

Case: A 63-year-old acromegalic woman admitted hospital for lassitude and dizziness. She has been diagnosed acromegaly 10 years ago and had two transsphenoidal operations. Remission wasn’t achieved. Then she started to use lanreotide (somatostatin analogue) and for 7 years she has been treated with it. In laboratory examination, basal plasma GH 1.21 ng/ml (NR:0–5); nadir GH level after glucose tolerance test, 1.2 ng/ml (NR: less than 1); IGF1, 129.1 ng/ml (NR: for ag...

Introduction: Primary hyperparathyroidism (PHPT) is a common endocrine disorder that is characterized by hypercalcemia and elevated or normal levels of parathyroid hormone (PTH). Most PHPT cases are incidentally discovered when routine laboratory analysis reveals hypercalcemia. PHPT should be considered in any person with elevated serum calcium (Ca) levels and no clear evidence of malignancy. Serum phosphorus (P) is low due to the phosphaturic effects of PTH and mostly in the ...

Ectopic secretion of corticotropin(ACTH) by nonpituitary tumors accounts for 10–15% of ACTH dependent Cushing’s syndrome (CS). Generally it is difficult to localize the ACTH secreting tumor by conventional imaging methods because these tumors are often small in size. Here we present a case of ectopic ACTH syndrome diagnosed with octreotide scan.Case: A 26-year-old male patient presented with moon face, purplish striae, supraclavicular fat pads ...

Giant cell granuloma is a skeletal manifestation seen now rarely in hyperparathyroidism due to early recognition of the disease. Lesions usually occur in the areas of intense bone resorption. They can affect mandible, maxilla, clavicle, ribs and pelvic bones. Most of the patients who have primary hyperparathyroidism are asymptomatic and are discovered incidentally during laboratory examinations. Here, we represent a female patient who was referred to endocrinology clinics beca...

The classic clinic manifestation of primary hyperparathyroidism (PHPT) is osteitis fibrosa cystica, a severe skeletal disease characterized by brown tumors, bone cysts and deformities, due to extremely elevated bone resorption elicited by continuously high parathyroid hormone (PTH) levels. In cardiovascular system there may be shortened QT interval, deposition of calcium in heart valves, coronary arteries, and myocardial fibers. Here, we report a case with PHPT, who have anore...

Pituitary adenomas which co-secrete GH and TSH accounts for <0.2% of all adenomas of the pituitary. Symptoms of hypertyroidism are usually masked by clinical manifestations of acromegaly. Here, we have reported the result of the primary one year long medical therapy in a case who was diagnosed to have adenoma co-secreting GH and TSH.Case: Seventy-years-old female patient has admitted with the complaints of excessive sweating, enlargement of hands and...

Well-known environmental factors which can lead to type 1 diabetes are viral infections, vaccines, diet, exposure to cow milk in infancy, vitamin D deficiency, drugs, maternal age, preeclampsia and low birth weight. Isotretinoin is an effective drug for acne treatment. It can cause dyslipidemia, elevated liver enzymes, insulin resistance and type 2 diabetes. Our case is type 1 diabetes developed after the use of isotretinoin and represented with diabetic ketoacidosis.<p cl...

Background: Generously supported by IPSEN)-->In this study we have aimed to calculate the QT dispersion in acromegaly patients and reveal its correlation with GH and IGF1.Materials and methods: Forty-one acromegaly patients were enrolled in the study. Another 41 patients with similar age, sex and comorbid disease distrubition have constituted the control group. We have evaluated the electrocardiograms (ECG) of ...

Hypertygiceridemia is responsible from the 1–4% of acute pancreatitis cases. When serum triglyceride level rises above 1000–2000 mg/dl, risk of having acute pancreatitis also increases. Medical therapy is usually inadequate for treatment of hypertryglyceridemia cases which cause severe and recurrent pancreatitis attacks. In our case we have reported a patient having recurrent attacks under medical therapy and underwent plasmapheresis.Case: 45 y...
