RESUMO
Objective To discuss the indication and efficacy for treating hypospadias with ure-throplasty of Pedicled preputial double-faced island flap(PPDIF). Methods Records of 99 children (mean age, 5.1 years; age range, 4 months-12 years)with hypospadias who underwent PPDIF oper-ation were reviewed. Of them, 56 cases were penile type of hypospadias, 24 cases of penile root type, 13 cases of scrotal type and 6 cases of perineal type according to Barcat classification. Based on Duck-ett technique, the partial preputial cortical plate remained and was displaced to gastr-penis with ure-thra. , and finally the new urethra would be covered by the cortical plate. Results During follow-up of average 2 years, 8 patients(8. 1%) developed urethral fistula, 1 (1.0 %) developed mild meatal ste-nosis, and 1(1.0 %) developed flap necrosis. The success rate for total PPDIF procedure was 89.90 % (89/99). And the success rate of simple PPDIF for cases with penile and penile root hypospadias, and PPDIF+Duplay for cases with serotal and perineal hypospadias were respectively 91.25 % (73/80) and 84.21%(16/19). respectively. Conclusions PPDIF is good for treating most hypospadias. Furth-more it make penis better shape. In the severe cases, PPDIF+Duplay prededure is recommended and the effect was affirmative.
RESUMO
Objective:The effect of the linseeds,VE and ethoxyquinoline in feed on the productive performance of the Hailanhong layers and ?-3 PUFA deposition in the yolk of laying eggs was studied. Method:Four hundred and eighty healthy layers of 48 weeks of age were randomly selected. The linseeds,VE and ethoxyquinoline of different levels in diet were fed on these layers. The indices of the productive performance and the fatty acids content of yolk were determined. The regression model of the fatty acids deposition was established. Results:The effect of the linseeds,VE and ethoxyquinoline in feed on the productive performance was slight. The most deposition of ?-3 PUFA was found by adding linseeds 15%,VE 0.17g/kg feed without ethoxyquinoline. Conclusion:The deposition of ?-3 PUFA in eggs could be regulated by controlling the proportion of linseeds and VE in feed with no effect on productive performance of layers.
RESUMO
ObjectiveTo report 18 cases of Bowen dis ea se and erythroplasia of Queyrat.MethodsClinicopatholog ical data of 18 cases of Bowen disease and erythroplasia of Queyrat were present ed.10 cases (mean age 49 year)underwent circumcision and local resection and 8 c ases electric coagulation.Results15 cases have been fo llowed up for 4～48 months.2 cases had new disease at an untreated area and the o ther 13 have been free of the disease.Recurrence ocurred in 2 were cured with 5% 5-fluorouracil cream external application.ConclusionsThe result of the surgical treatment for Bowen disease and erythroplasia of Qu eyrat is good and an alternative therapy with 5-fluorouracil for external appli cation may be considered.Adequate biopsy including deeper tissue is necessary fo r differential diagnosis between carcinoma in situ and invasive penile carcinoma or a variety of lesions of the male genitalia.
RESUMO
Objective To study the clinical and pathological features of a case of retroperitoneal desmoplastic small round cell tumor. Methods One case of desmoplastic small round cell tumor was presented with review of the literature. Results A 11 years old child complained of abdominal pain and a 9.0 cm?6.0 cm?3.0 cm cystic tumor located in the left retroperitoneal space near the left kindey was resected.The connective tissue was significantly proliferated around the tumor cell nests. Immunohistochemical staining revealed CD 99 (+) and EWS/WT1 (+). After resection of the tumor,chemotherapy was performed with DDP?ifosfamide and VP16. No tumor recorrence has been noted 16 months after operation. Conclusions Desmoplastic small round cell tumor has specific clinicopathologic stigmata occuring usually in young males and the tumor was characterized by expression of MIC2 gene product CD 99 and the EWS/WT1 protein. Surgical resection with cheomotherapy is the treatment of choice.
