(derman Medical Publ, 2013) Dulger, Ahmet Cumhur; Karadas, Sevdegl; Gonullu, Hayriye; Gultepe, Bilge; Tasdemir, Mehmet
Gaucher disease (GD) is an inborn error of metabolism that affects the recycling of cellular glycolipids. Glucosylceramide (also called glucocerebroside) accumulate within the lysosomes of cells. Gaucher's disease is most common lysosomal storage disease and its incidence is 1/75.000. Three types of this disease have been defined. During the course of disease, it was reported that hepatosplenomegaly, portal hypertension, hyperferritinemia, splenic infarcts and splenic nodules might develop. Therefore, as in our case; Gaucher's disease must be remembered in the setting of hepatosplenomegaly, portal hypertension, hyperferritinemia, splenic infarcts and splenic nodules of unknown etiology.

Evaluation of the Relationship Between Endogenous Gonadotropins and Female Sexual Function and Psychological Status in Predialysis and Hemodialysis Patients
(Taylor & Francis Ltd, 2012) Kurdoglu, Zehra; Soyoral, Yasemin Usul; Tasdemir, Mehmet; Kurdoglu, Mertihan
Objectives: To evaluate sexual function and psychological state and the factors affecting female sexual dysfunction in predialysis and hemodialysis patients. Design and methods: Forty-seven women with chronic renal failure including 22 predialysis patients, 25 hemodialysis patients, and 30 healthy controls were included in this study. Demographic and clinical variables of the patients were recorded. The sexual functions and psychological states of the patients, assessed by the Arizona Sexual Experiences Scale (ASEX) and Beck Depression Inventory (BDI), respectively, were compared between the groups. Results: Total ASEX scores, ability to reach orgasm, and BDI scores were significantly higher in predialysis and hemodialysis patients than controls, reflecting sexual dysfunction. The patients in the predialysis group were 6 and 3.8 times more likely to develop depressive symptoms compared to the controls and hemodialysis patients, respectively. The predialysis patients who showed depressive symptoms were 24 times more likely to develop sexual dysfunction compared to those without depression. Serum FSH and LH levels were also positively correlated with arousal and erection/lubrication scores in the predialysis patients with depressive symptoms. Conclusion: Female predialysis rather than dialysis patients might be more likely to develop depression. Those patients with depressive symptoms may also be at greater risk of developing sexual dysfunction in which increased gonadotropin levels and age may also be contributing factors. Therefore, psychiatric and gynecologic consultations may be beneficial.

Serum Malondialdehyde Levels, Myeloperoxidase and Catalase Activities in Patients With Nephrotic Syndrome
(Taylor & Francis Ltd, 2013) Begenik, Huseyin; Soyoral, Yasemin Usul; Erkoc, Reha; Emre, Habib; Taskin, Abdullah; Tasdemir, Mehmet; Aslan, Mehmet
Objectives: Some studies have indicated the pathophysiological importance of reactive oxygen species (ROS) in patients with nephrotic syndrome. Myeloperoxidase (MPO) is a leukocyte-derived enzyme-generating ROS that has been proposed to exert a wide array of pro-atherogenic effects throughout all stages of the atherosclerotic process. The aim of this study was to investigate the serum malondialdehyde (MDA) levels, MPO and catalase activities in patients with adult nephrotic syndrome. Patients and Methods: Twenty-four patients with nephrotic syndrome and 24 healthy controls were enrolled. Serum MPO activity, catalase activity, and MDA levels were assessed. Results: Serum MPO activity and MDA levels were significantly higher in patients with nephrotic syndrome than controls (both, P < 0.001), while catalase activity was significantly lower (P < 0.001). Serum catalase activity was found to be significantly correlated with MPO activity (r = -0.417, P = 0.003) and MDA levels (r = -0.532, P = 0.007). The serum MDA levels were also found to be significantly correlated with MPO activity (r = 0.419, P = 0.003). Conclusions: We concluded that serum MPO activity and oxidative stress were increased and that serum catalase activity was decreased in patients with adult nephrotic syndrome. In addition, these results indicate that increased MPO activity is associated with an oxidant-antioxidant imbalance that may contribute to atherosclerosis in patients with adult nephrotic syndrome.
