ACTA ENDOCRINOLOGICA (BUC)

Introduction. Vinegar is known with its positive impact on post-prandial dysmetabolism. The aim of this study was to\r\nelucidate the acute effects of high amount vinegar on blood glucose and lipid parameters.\r\nMaterial and Methods. Sixteen type 2 diabetic patients who had been treated with metformin only, were served a\r\nstandardized meal to which 50 g vinegar was added on the first day but not on the second day. Blood glucose, insulin and lipid levels were measured during fasting and at the second hour after intake of the meal.\r\nResults. Postprandial increase in the levels of venous blood glucose measurements was not different in the vinegar group when compared with the reference group (p=0.163). There was no significant difference on postprandial insulinemia (p=0.796). While investigating the effect of the vinegar on postprandial lipemia, no differences in triglyceride\r\nchanges was found between vinegar and reference group (p=0.816).\r\nConclusion. In this study in which we have tried to find an answer to the question about the effect of high amount grape\r\nvinegar on postprandial metabolism, no favorable or deleterious effect on postprandial changes of glycemia and\r\nlipemia was found.

Background. HDR syndrome is an autosomal dominant disorder characterized by hypoparathyroidism, sensorineural deafness, and renal dysplasia caused by mutation of the GATA3 gene. Case report. We describe a case of HDR syndrome diagnosed in a 46-yearold male patient. He had hand numbness, intermittent dizziness, and imbalance due to hypocalcemia. Physical examination was slim in appearance, had marfanoid features, and presented the typical apathetic face. He had a narrow rib cage and pectus excavatum deformity. Laboratory findings included serum calcium of 7.4 mg/dL, phosphorus of 4.87 mg/dL, albumin of 4.5 g/dL, intact parathormone (iPTH) of 13.3 pg/mL, 25(OH) D3 vitamin of 16.3 μg/L, daily urinary calcium excretion of 23.4 mg/day. Noncontrast computerized tomography (CT) of the brain showed bilateral basal ganglia calcification. Abdominal ultrasonography and CT showed the absence of renal tissue in the left kidney site and pelvis (left renal aplasia). Audiometry revealed mild sensorineural hearing loss at high frequencies. Conclusions. The patients with HDR syndrome are often diagnosed when they are examined for symptomatic hypoparathyroidism and deafness. To the best our knowledge, the present case is the second case of Barakat Syndrome reported from Turkey. The treatment of HDR syndrome is focused on clinical symptoms. The prognosis of the disease correlates with hypoparathyroidism and the severity of renal disease. HDR syndrome has an autosomaldominant inheritance, screening of family members is recommended for early diagnosis and treatment.

The incidence of primary adrenocortical insufficiency is 4.7 to 6.2 per one million. Among primary cancers developed in the adrenal gland, malignant lymphoma is very rare. We report here on an 82-year-old male patient who had primary adrenocortical insufficiency caused by bilateral adrenal lymphoma.
