A Pregnant Woman Who Underwent Laparoscopic Adrenalectomy due to Cushing's Syndrome.

Cushing's syndrome (CS) may lead to severe maternal and fetal morbidities and even mortalities in pregnancy. However, pregnancy complicates the diagnosis and treatment of CS. This study describes a 26-year-old pregnant woman admitted with hypertension-induced headache. Hormonal analyses performed due to her cushingoid phenotype revealed a diagnosis of adrenocorticotropic hormone- (ACTH-) independent CS. MRI showed a 3.5 cm adenoma in her right adrenal gland. After preoperative metyrapone therapy, she underwent a successful unilateral laparoscopic adrenalectomy at 14-week gestation. Although she had a temporary postoperative adrenal insufficiency, hormonal analyses showed that she has been in remission since delivery. Findings in this patient, as well as those in previous patients, indicate that pregnancy is not an absolute contraindication for laparoscopic adrenalectomy. Rather, such surgery should be considered a safe and efficient treatment method for pregnant women with cortisol-secreting adrenal adenomas.

Evaluation of chromosomal damage, cytostasis, cytotoxicity, oxidative DNA damage and their association with body-mass index in obese subjects.

Over-weight and obesity are serious problems that increase the risk not only for chronic diseases like diabetes and heart disease but also of various types of cancer. This study was conducted to evaluate cytokinesis-block micronucleus cytome (CBMN-cyt) assay parameters and plasma concentrations of 8-hydroxy-2'-deoxyguanosine (8-OHdG), and their relationship with age, body-mass index (BMI) and waist-to-hip ratio (WHR) in 83 obese, 21 over-weight and 21 normal-weight subjects. Frequencies of micronuclei (MN), nucleoplasmic bridges (NPB), nuclear buds (NBUD), and apoptotic and necrotic cells in lymphocytes of obese subjects were found to be significantly higher than those found in normal-weight and over-weight subjects (p<0.01 and p<0.05), whereas plasma concentrations of 8-OHdG in obese subjects were lower than those observed in normal-weight and over-weight subjects (p<0.05 and p<0.01, respectively). There was a negative correlation between age and frequency of necrotic cells and NDI (p<0.05), whereas there was no correlation between BMI, WHR, CBMN cyt assay parameters and plasma 8-OHdG in normal-weight subjects. In over-weight subjects, a negative correlation was observed between age and NDI (p<0.01) and a positive correlation between age and frequency of NPB (p<0.01) and between BMI and frequency of NBUD (p<0.05). In obese subjects, a negative correlation was observed between age and NDI (p<0.01) and between BMI and NDI (p<0.05), whereas no correlation was observed between WHR and CBMN-cyt assay parameters and plasma 8-OHdG. However, frequencies of MN, NPB, NBUD, apoptotic and necrotic cells in total over-weight/obese (p<0.01/p<0.05) and all subjects (p<0.01) increased with increasing BMI. The increase in genomic damage (MN, NPB and NBUD) in obese subjects and the positive correlation between genomic damage and BMI in total over-weight/obese subjects indicate that obesity increases genomic damage and may be associated with an increased risk of cancer, because an increase in MN frequency is a predictor of cancer risk.

The results of therapeutic plasma exchange in patients with severe hyperthyroidism: a retrospective multicenter study.

Hyperthyroidism characterized by elevated serum levels of circulating thyroid hormones. The aim of hyperthyroidism treatment is to achieve a euthyroid state as soon as possible and to maintain euthyroid status. However, drug withdrawal and utilization of alternative therapies are needed in cases in which leucopenia or impairment in liver functions is observed during medical therapy. In the present study, we aimed to present our cases which underwent therapeutic plasma exchange (TPE) due to severe hyperthyroidism. The results of 22 patients who underwent therapeutic plasma exchange due to hyperthyroidism in Apheresis Units of Erciyes University and Gaziantep University, between 2006 and 2012, were retrospectively reviewed. These cases had severe thyrotoxic values despite anti-thyroid drug use. After TPE, we observed a significant decrease in free thyroxin (FT4) (p<0.001) and free triiodotyhronin (FT3) (p<0.004) levels. There was statistically significant increase in the mean values of TSH levels after TPE (p<0.001). Clinical improvement was achieved in hyperthyroidism by TPE in 20 cases (91%). Both FT3 and FT4 levels remained above the normal limits in two of 22 patients. TPE should be considered as an effective and safe therapeutic option to achieve euthyroid state before surgery or radioactive iodine treatment. TPE is a useful option in cases with severe hyperthyroidism unresponsive to anti-thyroid agents and in those with clinical manifestations of cardiac failure and in patients with severe adverse events during anti-thyroid therapy.
