    ABSTRACT: The severe ischemia or necrosis of the glans penis is a rarely seen complication after circumcision. We report the case of a 7-year-old boy with severe glans penis ischemia occurring 24 hours after circumcision with local anesthesia (0.1% xylocaine containing ephedrine). His hemogram and levels of proteins C and S and fibrinogen were normal, but the D-dimer level was higher than normal (2.57 mg/L; normal level 0-0.5 mg/L). Normal blood flow was indicated on color Doppler ultrasonography. The severe ischemia in the glans penis was successfully treated with subcutaneous injection of enoxaparin (low-molecular-weight heparin) for 5 days, and the appearance of the glans was close to normal on the fifth day. The patient did not require any surgical intervention and was discharged without sequelae. As a result, we consider that ischemia of the glans penis may initially be managed with enoxaparin, especially in cases in which the D-dimer level is higher than normal.

    ABSTRACT: Some biopsy techniques may cause oxidative stress. Therefore, we aimed to evaluate the possible role of testicular biopsy-induced damage on production of reactive oxygen species using quantitative and biochemical methods. Adult male Wistar albino rats were randomly divided into five groups. Group 1 (sham) (n = 6) was sham operated. Group 2 (n = 7) underwent fine-needle aspiration testicular biopsy. Group 3 (n = 6) underwent microscopic testicular sperm extraction (micro-TESE). Open testicular biopsy was performed to rats in group 4 (macro-TESE) (n = 8). Group 5 (n = 7) underwent Tru-cut biopsy. Six weeks after the initial operations, orchiectomies were performed. Oxidative stress biomarkers such as superoxide dismutase (SOD) and catalase (CAT) activities, and malondialdehyde (MDA) in biopsy samples were measured as spectrophotometric. Compared with group I, SOD and CAT activities, and MDA levels were elevated significantly in the fine-needle aspiration group, in the macro-TESE group and in the Tru-cut biopsy group (groups II, IV, and V), (p < 0.05). However, there were no significant differences between group I and group III (p > 0.05). These data suggest that micro-TESE biopsy is the best technique among all others. All of the biopsy techniques except micro-TESE may cause the overproduction of reactive oxygen species. We consider that the increased antioxidant enzyme activities (CAT, SOD) may reflect the cellular response against oxidative stress in these groups.

    ABSTRACT: Purpose. Fournier's gangrene is a fulminant and destructive inflammation of the scrotum, penis, and perineum. The objective of this study was to compare 2 different approaches to wound management after aggressive surgical debridement. Methods. Data from 14 patients with Fournier's gangrene were retrospectively collected (2005-2011). Once the patients were stabilized following surgery, they were treated with either daily antiseptic (povidone iodine) dressings (group I, n = 6) or dressings with dakin's solution (sodium hypochloride) (group II, n = 8). Results. The mean age of the patients was 68.2 ± 7.8 (55-75) years in group I and 66.9 ± 10.2 (51-79) years in group II. Length of hospital stay was 13 ± 3.5 (7-16) days in group I and 8.9 ± 3.0 (4-12) days in group II (P < 0.05). The number and rate of mortality was 1/6 (16.7%) in group I, and 1/8 (12.5%) in group II. Conclusions. The hospitalization time can be reduced with the use of dakin's solution for the dressings in the treatment of FG. Also, dressings with dakin's solution seems to have favorable effects on morbidity and mortality. Consequently dakin's solution may alter the treatment of this disastrous disease by reducing cost, morbidity and mortality.

    ABSTRACT: To compare reactive oxygen species (ROS) and antioxidants in internal spermatic vein tissue of men with varicocele and a control group with inguinal hernia. Also to compare the levels of oxidants and antioxidants in infertile and fertile men with varicocele. 48 varicocele patients and 12 non-varicocele inguinal hernia patients participated in this study. The varicocele group was again divided into two groups--fertile men with varicocele and infertile men with varicocele. Internal spermatic vein tissue samples were obtained. The level of the malondialdehyde (MDA), an indicator of oxidative stress, and the activities of antioxidant enzymes (defense systems) against oxidative stress such as superoxide dismutase (SOD) and catalase (CAT) were estimated in these tissue samples. The mean level of MDA in the varicocele group was significantly higher than in the hernia group, whereas the levels of antioxidants (SOD and CAT) were significantly lower in the varicocele group than in the hernia group. When compared with the subgroups of the varicocele group, the MDA levels and SOD and CAT activities were significantly higher in the infertile varicocele group than in the fertile varicocele group. Antioxidant enzyme levels generally decrease due to a high consumption in varicocele patients. On the contrary, in our study both MDA and antioxidant enzymes increased in the internal spermatic venous wall of infertile varicocele patients. This situation may be explained by an adaptation against oxidative stress in varicocele, which could be defined as a chronic process.
