Apart from the other members of PDE inhibitors' family, enoximone does not enhance renal ischemic reperfusion injury: the effects of enoximone on renal ischemia reperfusion.

Many pharmacological agents were investigated for the prevention of renal ischemic reperfusion (IR) injury as well as the phosphodiesterase (PDE) inhibitors. The aim of the study was to examine the possible renoprotective effect of enoximone as a member of this family on IR injury. Thirty-six Wistar-Albino rats were allocated to six groups. Sham (S) and control groups (E1, E2) only received 0.09% NaCl, 5 mg/kg and 10 mg/kg enoximone via caudal caval vein, respectively. In ischemia (I) and treatment groups (IE1, IE2), the rats were subjected to bilateral renal artery occlusion and were given 0.09% NaCl, 5 mg/kg and 10 mg/kg enoximone in the same route, respectively. Bilateral kidneys were removed at the sixth hour of laparotomy for histopathological and biochemical analysis, such as superoxide dismutase, myeloperoxidase, malonyldialdehyde, and nitric oxide end products. Blood samples were taken in order to evaluate renal function tests. The data were analyzed by using one-way analysis of variance, and p < .05 was considered to be statistically significant. The worst results were achieved in ischemia group (p < .05). Treatments groups showed nearly similar findings with this group (p < .05). There was no significant difference between control and sham groups. In this study, we found that apart from the other members of the PDE inhibitors' family, enoximone did not contribute to the attenuation of IR injury of kidney.

Second branchial anomalies in children.

AIM: The aim of this study was to evaluate the data of our patients who had been treated for second branchial anomalies in the last 10 years. Here we report our clinical experience in second branchial anomalies with a review of the literature. PATIENTS AND METHODS: We evaluated retrospectively the data of 14 patients, who had been operated on between 1994 and 2004 for second branchial anomalies, in relation to age, sex, complaint at application, diagnostic test, surgical procedures and histopathologic findings. RESULTS: The mean age of the patients (8 female, 6 male) was 5.3 years (range = 1.5-16). The anomalies were usually located on the left side of the neck (n = 6). There were only 3 cases with bilateral anomalies. The majority of the lesions were sinuses (93%). The most frequent clinical feature was the presence of persistent discharge from an external (cutaneous) orifice. All lesions were excised by performing a second step ladder incision. Eight of the lesions were removed under the guidance of 3/0 polypropylene suture. No postoperative complication or recurrence was observed during the follow-up period. CONCLUSIONS: Second branchial arches anomalies are the most common branchial anomalies. Sinuses are more frequently encountered in children. Definitive treatment for these lesions is surgical excision. A polypropylene suture can be inserted into the tract as a guide to prevent incomplete excision.
