Insulin-mediated pseudoacromegaly with nonfunctioning pituitary adenoma

Celik Mehmet , Ayturk Semra , Yilmaz Bulbul Buket , Guldiken Sibel

Pseudoacromegaly is a rare disorder characterized by cutaneous manifestations of growth hormone excess but with normal growth hormone levels or IGF-1. This condition described in patients with insulin resistance, hypothyroidism, pachydermoperiostitis and drug intake such as minoxidil. The hyperinsulinaemia impaired metabolic signalling may activate intact mitogenic signalling pathways and stimulate pathological tissue growth.A 41-year-old man presented w...

Hungry bone syndrome following parathyroidectomy

Soysal Atile Neslihan , Ekiz Bilir Betul , Guldiken Sibel

Aim: Hypocalcemia is a common problem after parathyroidectomy but is generally transient. In some cases the postoperative hypocalcemia is severe and prolonged despite normal or even elevated levels of parathyroid hormone (PTH). This phenomenon, called the hungry bone syndrome (HBS), occurs due to sudden withdrawal of PTH leading to a marked net increase in bone uptake of Ca, P, and Mg. We aimed to evaluate predictive factors for HBS development after parathyroidectomy.<p c...

Receptor activator of nuclear factor kappa β ligand and osteoprotegerin levels in the patients with diabetic nephropathy

Kuzuguden Cigdem , Guldiken Sibel , Ustundag Sedat , Ozgen Zeren , Demir Muzaffer

Aim: The aim of this study was to investigate the relationship between the clinical and laboratory findings of metabolic bone disease regarding the levels of osteoprotegerin (OPG) and the receptor activator of nuclear factor kappa B ligand (RANKL) in the patients with diabetic nephropathy.Material and method: This study includes 61 type 2 diabetic patients and age-, sex-matched 20 healthy subjects. Diabetic patients were divided into three groups accordi...

Resting energy expenditure in impaired glucose metabolism

Bilir Betul Ekiz , Atile Neslihan Soysal , Bilir Bulent , Guldiken Sibel

Introduction: Indirect calorimetry is the most frequently used method to measure resting energy expenditure (REE), but the great expense of equipment precludes its widespread use. The best known REE calculation formula is the ‘Harris and Benedict Formula’. The aim of this study is to assess the impact of glucose metabolism status on REE.Methods: Data from 110 subjects with impaired glucose tolerance (IGT), 108 subjects with impaired fasting glu...

Case with metastatic lung cancer who developed adrenal insufficiency

Bulbul Buket Yilmaz , Celik Ece , Celik Mehmet , Ayturk Semra , Ustun Funda , Guldiken Sibel

Adrenal metastasis is common (35%) among the patients with lung cancer, while less than 3% of the patients develop bilateral adrenal metastasis. Adrenal metastases are generally small and clinically asymptomatic. Adrenal insufficiency is rare despite the presence of adrenal metastasis. Lam et al. reported this ratio as 0.7%. We aimed to present a case with lung cancer and bilateral adrenal metastasis who developed adrenal insufficiency.A 63-year old male...

A rare case: adrenal lymphangioma

Durmus Yusuf , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Can Nuray , Tastekin Ebru , Guldiken Sibel

Adrenal lymphangioma is a rare benign tumors of the adrenal gland. Because of the increased use of imaging methods in recent times, the diagnosis is usually made incidentally. It is usually due to malformation between the lymphatic and the venous system. Those with small indiameters are generally asymptomatic and can be evacuated by needlea spiration. However, surgery is recommended for cysts over 6 cm in diameter due to risk of infection, bleeding, compression of neighboring ...

A rare case: non-islet cell tumor hypoglycemia with adrenal insufficiency

Asoglu Veysi , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Ustun Funda , Guldiken Sibel

Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome and is the second most common cause of tumor-related hypoglycemia following insulinoma. Its prevalence is not known and is likely that many cases would go undiagnosed. In here, we describe a patient with PNET who presented with severe hypoglycemia.A 37-year-old male with known metastatic Pancreatic neuroendocrine tumors (PNET) presented with weight loss, sweating, and tremor, epi...

A rare cause of respiratory failure: Anaplastic carcinoma

Celik Ece , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Can Nuray , Serez Bilkay , Guldiken Sibel

Anaplastic thyroid carcinoma (ATC) is one of the most aggressive and lethal human malignancies. The median survival time following diagnosis is typically six months or less. Rapidly growing tumors may cause respiratory failure by compressing trachea. A 71-year-old woman presented with 1-month history of dyspnea, cyanosis and rapidly enlarging neck mass for the past 2 weeks. She had been suffering from multinodular goiter disease. Physical examination revealed a large, fixed an...

The effect of diabetes on the duration and cost of treatment in patients with acute ischemic stroke

Guldiken Baburhan , Namli Merve , Celik Burak , Celik Mehmet , Bulbul Buket Yilmaz , Guldiken Sibel

Diabetes is an important risk factor for ischemic stroke. Hyperglycemia observed in acute ischemic stroke is accepted as a poor prognostic factor. In the present study, our aim is to investigate the effect of diabetes on the duration and cost of treatment in acute ischemic stroke.Three hundred sixty two acute ischemic stroke patients that were hospitalized in the university neurology clinic in 2015 were retrospectively evaluated. Patients that have diabe...

The need of change in the treatment options for diabetes in acute ischemic stroke

Guldiken Baburhan , Celik Burak , Namli Merve , Bulbul Buket Yilmaz , Celik Mehmet , Guldiken Sibel

Diabetes that is an important risk factor for ischemic stroke should also be well-treated in acute ischemic stroke patients for the secondary prevention against the next strokes. In the present study, we investigated the rate of the treatment changes in diabetic acute ischemic stroke patients during their stay at hospital.One hundred twelve acute diabetic ischemic stroke patients that were hospitalized in the university neurology clinic were retrospectiv...
