IntroductionPituitary apoplexy is seen in 1.5–27.7% of pituitary adenomas. Common etiologies include hypertension, diabetes mellitus, radiotherapy, contrast-enhanced MR, surgery, drugs, anticoagulant, antithrombotic, estrogen, head trauma and pregnancy. SARS-CoV-2 had spread rapidly, and caused COVID-19 pandemic. Although it mainly causes respiratory problems, there may also be extrapulmonary involvement. COVID-19 infection is associated with hemorr...

IntroductionPituitary gland tumors constitute approximately 10–15% of primary brain tumors, and posterior pituitary tumors are extremely rare. Granular cell tumor (GCT) is a low grade non-neuroendocrine neoplasm. Here, we will present our case who was found to have GCT during follow-up of diabetes insipidus (DI).CaseA 23-year-old male patient applied to our outpatient clinic for routine control. 12 years...

Objectives: The novel coronavirus disease-2019 (COVID-19) is the fastest-spreading disease worldwide, with over 380 million cases and 5 million deaths. The presence of diabetes mellitus (DM) in patients with COVID-19 was associated with mortality, acute respiratory distress syndrome, disease progression. COVID-19 was progressed with some hematological disorders, especially lymphopenia. Studies implicated that neutrophil-to-lymphocyte ratio (NLR) level can be a reliable marker ...

Aim: Postoperative hypocalcemia is seen in 26-42% patients after parathyroidectomy.There are quite a lot of studies investigating preoperative factors that might be used to predict postoperative hypocalcemia in thyroidectomized patients, however there are less studies in parathyroidectomized patients.In this study, our aim was to determine whether any preoperative clinical, laboratory or ultrasonographical feature anticipate hypocalcemia in parathyroidectomized patients due to...

Background: Medullary thyroid cancers (MTC) originate from parafollicular C cells and constitute 3-5% of all thyroid cancers. Calcitonin (CT) measurement is useful in the diagnosis of MTC. The sensitivity and specificity of CT are low in the measurement alone, and the sensitivity and specificity increase when used with pentagastrin and calcium stimulation tests. However, the difficulty of accessing pentagastrin, the uncertainty of the cut-off value in calcium stimulation tests...

Backgorund: Adrenal incidentalomas (AI) are lesions discovered incidentally on imaging without clinical symptoms or examination findings. AI can produce hormones in 5-30% of cases. Autonomic cortisol secretion (ACS) is the most common of these. Although ACS is asymptomatic, it increases the risk of metabolic disorders.Methods: Patients aged<18 years with adrenal adenoma and upper abdominal MRI who presented and were examined in the endocrinology outp...

A 36 years of old patient was admitted to the intensive care unit of cardiology when he experienced palpitations and orthopnea. The patient’s complaints started about 2 years ago as syncope and sudden shortness of breath. Thorax CT showed pleural effusion and increased cardiothoracic index. Findings on ECHO were : Ejection fraction 35%, severe mitral regurgitation and global hypokinesia. Coronary angiogram showed a fibrocalcific plaque noted in in the distal LAD. The pati...

Aim: It is hypotethically thought that increased frequency of breast cancer in patients with primary hyperparathyroidism(PHPT)may be due to the fact that calcium accumulation in the breast may be higher in patients with PHPT giving rise to more breast-related examinations. Although there are many studies or case reports showing calcification in many organs and tissues, in PHPT, there is not any study investigating breast calcification in these patients in the literature. We ai...

Background: Hypoparathyroidism (HypoPT) is a rare condition that is characterized by hypocalcemia and hyperphosphatemia due to low or inappropriately normal serum levels of parathyroid hormone (PTH) for at least 6 months. The long-term complications of hypoparathyroidism indicate the necessity of screening them. In the follow-up of these patients according to hypoparathyroidism guidelines is recommended; calcium, phosphorus, albumin, magnesium, creatinine, and eGFR levels shou...

Introduction: Insulinoma is a rare neuroendocrine tumor that is difficult to diagnose due to its obscure location. Conventional radiographic methods have low sensitivity and are inadequate to detect insulinoma. Selective arterial calcium stimulation test (SACST) is 95–100% sensitive in the diagnosis of insulinomas. Here, we presented two cases of insulinoma that could not be located by radiographic methods and evaluated them with SACST.Case 1: A 48-...
