The fact that there were no differences in terms of wound infection or recurrence rates between the three groups, and the relatively shorter period for returning to work, emphasize the usefulness of the excision and repair techniques in the surgical treatment of pilonidal disease.

We report a case of hydatid cyst of the pelvis in a 36-year-old woman presented with right adnexal cystic mass with similar cystic lesions in the liver. Laparatomy revealed a right paraovarian cystic mass densely adhered to the uterus, to the pelvic side wall, and to the right fallopian tube. Histopathological examination of the cyst wall showed the cuticular layer of the cyst. Cystic liver lesion was later proved to be hepatic hemangioma by magnetic resonance imaging.

BACKGROUND Considering recent findings that both urokinase plasminogen activator receptor (uPAR) and plasminogen activator inhibitors (PAIs) are involved in tumor growth through an urokinase‐type plasminogen activator (uPA) activity‐independent mechanism, the relation between the presence of these factors in tumor tissue and the clinicopathologic variables in colorectal carcinoma was reevaluated. METHODS In 100 colorectal carcinoma patients, antigen levels of u‐PA, uPAR, and PAI‐1 and PAI‐2 were assayed in both tumor tissues and their normal counterparts. Plasma levels of soluble uPAR also were determined. RESULTS All uPAR, uPA, PAI‐1, and PAI‐2 antigen levels in tumor tissue were significantly higher than those in normal tissue. Levels of both uPAR and PAI‐1 were significantly higher (3.09 ± 1.37 and 6.63 ± 7.49, respectively) in large tumors (≥50 mm in greatest dimension) than those in smaller tumors (< 50 mm) (2.50 ± 1.07 and 2.72 ± 2.70, respectively) (P < 0.05). Significant positive correlation coefficients (r) were obtained between tumor size and the calculated ratios of PAI‐1/uPAR (r = 0.490; P < 0.0001) and PAI‐1/uPA (r = 0.469; P < 0.0001). In addition to liver metastases (P = 0.004) and lymph node involvement (P = 0.04), high levels of uPAR (P = 0.05) also were found to be of independent prognostic value by multivariate analysis. CONCLUSIONS Higher expression of uPAR was related to poor prognosis of patients with colorectal carcinoma and excess amounts of PAI‐1 over uPAR or uPAR‐bound uPA appeared to play an important role in tumor progression.

Prophylactic dexamethasone 8 mg i.v. significantly reduced the incidence of PONV in patients undergoing laparoscopic cholecystectomy. Dexamethasone 8 mg was as effective as ondansetron 4 mg and granisetron 3 mg, and it was more effective than placebo.

In this study, the long-term effects of mesh and its localisation (i.e. anterior or posterior) on testicular perfusion and testicular function were evaluated in groin hernia patients. Testicular function has been evaluated with spermiogram and testicular perfusion with colour Doppler ultrasonography. Group I: consisted of 30 posterior preperitoneal mesh repair patients Group II: consisted of 30 anterior tension-free repair patients. The operation types were randomised with a systematic sampling method. There was no statistically significant difference between pre-operative and postoperative spermiogram results for both groups. No statistically significant difference was found between the two groups in terms of Doppler flow parameters (PSV, EDV, RI and PI) for pre-operative, early and late postoperative periods. When Doppler flow parameters were compared for group I, statistically significant differences were found between pre-operative and early postoperative values. No statistically significant difference was found between pre-operative and late postoperative values. This is also true for early postoperative values versus late postoperative values. When Doppler flow parameters were compared for group II, statistically significant differences were found between pre-operative and early postoperative values. No statistically difference was found between pre-operative and late postoperative values. This is also true for early postoperative values versus late postoperative values. These results support the idea that inguinal mesh application is still a safe procedure in patients with no children or who are undergoing infertility treatment, where testicular function is important.
