Cushing’s syndrome as a result of ectopic adrenocorticotropic hormone (ACTH) secretion, is associated with various tumors. Lung squamous cell carcinoma (LUSC) causing ectopic ACTH syndrome is a very rare condition. A 70-year-old male patient with a history of LUSC was admitted to our clinic for evaluation of worsening delirium and hypokalemia. Two courses of pembrolizumab were administered to our patient who was diagnosed with LUSC a month ago. At presentation, neurologic...

Tuberculosis (TB) is a disease that affects all organs and progresses with a wide variety of clinical manifestations. Cases of extrapulmonary tuberculosis (EPTB) are particularly difficult to diagnose because of its atypical course.Case: A 32-year-old female patient was evaluated in our clinic with the complaint of localized swelling in both supraclavicular regions (ScR) for one and a half months. There were no fevers, cough, or weight loss symptoms pres...

: X-linked nephrogenic diabetes insipidus (NDI) is a rare disease caused by a defect in the vasopressin V2 receptor in renal collecting duct cells which is encoded by the AVPR2 gene (Xq28). More than 200 mutations have been found comprising missense, nonsense, small insertions and deletions, large deletions and complex rearrangements in AVPR2 gene to date. In this study, a 6-year-old boy was referred to the Pediatric Nephrology Department of Kecioren Research...

Familial central or neurohypophyseal diabetes insipidus (FNDI) results from insufficient production of antidiuretic hormone arginine vasopressin, which is caused by mutations in arginine vasopressin-neurophysin II gene (AVP-NPII). In this study, we present the clinical features of a male Turkish patient with autosomal dominant neurohypophyseal DI caused by a novel mutation (p.E108D). The prospective clinical data were collected for the proband patient and his family members. T...

Diabetes insipidus (DI) is a disorder which is rarely seen and it is characterized by polydipsia and polyuria. Inadequate secretion of arginine vasopressin (AVP) from hypothalamus or inadequate response of kidney cells to AVP could be causes of DI. Therefore, any mutations in AVPR2, AVP and AQP2 genes which are the parts of that stimulation and response pathyway can cause DI. In this study, mutational analyse was performed for A45T mutation in AQP2 gene. We present a novel hom...

Primary adrenal lymphoma(PAL) is very rare and constitutes <1% of cases of extranodal lymphomas. Most common subtype of PAL is diffuse large B cell lymphoma. A 46-year-old male patient without any underlying disease was admitted to our hospital with a complaint of bilateral back pain, cough and fever. His laboratory tests revealed a hemoglobin: 5 g/dl (14–17.5), white blood cell: 3.8 103/µl (4.4–11.3), platelet: 111 103/µl (130&#...

Objective: Thyroid hormones are powerful mediators of numerous physiological and metabolic processes, including blood clotting, and thyroid dysfunction can adversely affect various stages in the coagulation cascade. Mean platelet volume (MPV) is used to measure platelet size and may indicate platelet activity. Studies have reported that increased MPV is associated with atherosclerotic lesions and cardiovascular diseases, and conflicting results have been reported for the relat...

BackgroundPrimary hyperparathyroidism (PHPT) is known to be associated with cardiac and metabolic morbidities. Chronic hypercalcemia in PHPT patients has been reported to be associated with an increased risk of mortality, particularly due to cardiovascular disease, during long-term follow-up. Endocan is secreted by vascular endothelial cells and is involved in the regulation of important endothelial functions. Endocan secretion increases in a variety of ...

Diabetes caused by immune checkpoint inhibitors is extremely rare. A 48-year-old male patient with a diagnosis of squamous cell cancer in the external auditory canal and operated on received adjuvant radiotherapy. When relapse was seen, 6 cycles of 5-fluorouracil, carboplatin, and cetuximab were administered. The patient was admitted to the hospital with nausea, vomiting, and abdominal pain 10 days after the second cycle infusion, when pembrolizumab was started when the crania...

Background: Patients diagnosed with acromegaly have an increased prevalence of sleep apnea syndrome(SAS). The data are scarce regarding the effects of continuous positive airway pressure(CPAP) use on cardiovascular parameters in these patients. We aimed to prospectively evaluate the cardiovascular effects of CPAP in patients with SAS and acromegaly.Methods: Adult patients with newly diagnosed acromegaly were performed metabolic (body mass index (BMI), gl...
