In prolactinomas, today first choice of treatment is medical treatment with dopamine agonists. Cavernous sinus invasion is not uncommon in prolactinomas and stands out as a blocking factor for surgical removal of the tumor fully. In our study, the presence of cavernous sinus invasion was to investigate the effect on the results of surgical and medical treatment in prolactinomas.Eighty-seven patients followed up with a diagnosis of prolactinoma were inclu...

Prolactinomas are more common tumors by 60% among the hypophysis adenomas. These are often benign, but may present differences in terms of tumor size and treatment responses. Aim of this study was investigate the relationship of serum prolactin levels with tumor size and invasiveness in the prolactinomas.113 patients with the diagnosis of prolactinoma were included to study. Pretreatment plasma levels of prolactin in the time of diagnosis and sella MR im...

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 ...

Introduction: Fine-needle aspiration (FNA) biopsy of thyroid nodules is minimally invasive and safe. The clinical importance of the thyroid nodule evaluation is primarily related to the need to exclude thyroid cancer. We aimed to investigate the relationship between preoperative FNA cytology and results of thyroidectomy in this study.Materials and Methods: Histopathologic examination reports of 302 patients undergoing thyroidectomy and preoperative FNA c...

Rhabdomyolysis is a characterized by muscle necrosis and release of intracellular muscle constituents into the circulation. Most cases are associated with a predisposing factor such as high dose statin therapy, diabetes, old age, female gender, renal failure or hypothyroidism.An 80-year-old woman presented with severe and generalized muscle pain. Her medical history included hypertension, congestive heart failure, chronic atrial fibrillation and a thy...

Benign symmetric lipomatosis (BSL) is a very rare disorder characterized by the growth of uncapsulated masses of adipose tissue, predominantly located in the neck and shoulders. Benign symmetric lipomatosis is usually described in adults between 30 and 60 years of age and is slightly more frequent in men with heavy alcohol consumption. A 70-year-old woman presented with a great growth of soft tissues in the cervico-occipital region who had never consumed any alcohol. Laborator...

A 50-year-old man admitted to our institution with labile hypertension. His blood pressure was 150/90 mmHg and the pulse rate was 96 beats per minute. He had hypertensive attacks every 2–3 days. His blood pressure was found 210/110 mmHg at hypertensive attact. He had palpable thyroid nodule. Ultrasonography of the thyroid gland showed a 2.6 cm sized, irregularly marginated, calcified thyroid nodule. His serum free thyroxine (fT4), free triiodothyronine (fT3), thyrotropin ...

Many causes of levothyroxine malabsorption have been described in the literature such as celiac disease, giardiasis, severe liver cirrhosis and drug interactions. A 27-year-old woman admitted to our institution with overt hypothyroidism symptoms. She had total thyroidectomy for thyroid papiller carcinoma and was using 400 μg/day levothyroxine (LT4). Her serum free thyroxine (fT4), free triiodothyronine (fT3) and thyrotropin stimulating hor...

Hyperinsulinemia that occurs due to insulin resistance play an important role on the development of type 2 diabetes and hypertension. It is shown that apart from their angiotensin II receptor blockage effect, telmisartan and irbesartan can activate intracellular hormone receptor PPARγ. Owing to this dual effect, telmisartan and irbesartan can improve cardiovascular risk factors related to insulin resistance. The aim of this study was to compare the effects of telmisartan ...

PURPOSE: To report a case of Cushing’s syndome caused by ectopic ACTH secretion related to a thymic carcinoid presented with trombositopenia.CASE: years old male presented with fatigue, skin rash. At presentation, physical findings showed Cushingoid appearance, with moon face, hyperpigmentation, easy bruising and buffalo hump. His laboratory findings showed platelet: 90.000 (150.000–450.000), ACTH: 609 pg/ml (0–46 pg/ml), baseline cortisol...
