[Study of urinary continence after radical prostatectomy. Comparison between laparoscopic and retropubic prostatectomy based on a series of 251 cases]. / Etude de la continence urinaire après prostatectomie radicale. Comparaison entre prostatectomie rétropubienne et coelioscopique à propos de 251 cas.

INTRODUCTION: The objective of this study was to compare the results in terms of continence and quality of life between retropubic radical prostatectomy and laparoscopic radical prostatectomy, performed according to the same principle of retrograde dissection from the apex. MATERIAL AND METHOD: The series was composed of 120 patients undergoing retropubic radical prostatectomy and 131 patients undergoing laparoscopic radical prostatectomy performed in the Limoges hospital, urology and andrology department, between January 2002 and September 2005. Continence was evaluated by anonymous self-administered questionnaire sent to the patient's home. Pain was evaluated by visual analogue scale and narcotic consumption. Predictive factors of continence were analysed. RESULTS: The two groups were comparable in terms of pathological stage, Gleason score and age. The laparoscopy group comprised more patients with a history of transurethral resection of the prostate and more obese patients. No significant difference was observed between laparoscopy and laparotomy for degree of continence (71% versus 76%; p>0.05), time to return of continence (13 weeks versus nine weeks; p>0.05) and rate of mild (14% versus 13%), moderate (7% versus 6%) and severe (7% versus 5%) urinary incontinence. The anastomosis secondary stenosis rate was also identical in the two groups. Age was found to be a predictive factor for continence, especially for the mean time to return periods of continence. The patient's weight, prostate weight and TNM stage were not predictive factors for incontinence. The incontinence rate was 40% for salvage prostatectomies after radiotherapy. The mean duration of bladder catheterization was 6.9 days in the laparoscopy group and 7.2 days in the laparotomy group. Narcotic consumption was significantly lower in the laparoscopy group (21 mg versus 36 mg; p<0.05). CONCLUSION: Laparoscopic radical prostatectomy appears to give the same results in terms of continence as retropubic radical prostatectomy. However, these procedures were the first laparoscopic prostatectomies performed in the department, suggesting that, with greater experience, the results of laparoscopy could become superior to those of laparotomy. The laparoscopic technique also appeared to provide better patient comfort by decreasing postoperative pain.

Anterior urethral valves and diverticula.

Obstructive lesions of the anterior urethra (valves, diverticula) are rare and can be difficult to diagnose. One recent case led us to review existing international reports; there are case histories for 260 patients over a 20-year period. The anatomical interpretation of these lesions is far from being unequivocal but many authors clearly distinguish between valves and diverticula, the basic difference being in the contiguity between the anomaly and the corpus spongiosum. Where the clinical presentation depends on age, the diagnosis depends essentially on voiding cysto-urethrography, which must image the whole urethra. Generally, the treatment for valves is simple, consisting of endoscopic resection. For diverticula it is not always necessary or desirable to remove the diverticulum; if there is a well-formed distal obstructing lip, removing it may be enough to cure the obstruction.

Persistence of phonological processing deficits in college students with dyslexia who have age-appropriate reading skills.

This study investigated the phonological processing skills of university students with dyslexia. Fifty-nine students participated in this study: 28 with reading disabilities based on recent psychological assessments and a history of early and persistent reading problems; and 31 controls. The two groups did not differ on estimates of verbal and nonverbal abilities. The dyslexia group performed significantly less well on standardized measures of reading and spelling. However, the dyslexia group scores on these measures fell within the average range. The main dependent variables were subsumed under three areas of phonological processing: phonological awareness, phonological recoding in lexical access, and phonological recoding in working memory. The control group performed significantly better on all phonological processing measures, particularly those measures involving accuracy and response times. Despite age-appropriate performances on standardized reading and spelling measures, phonological processing deficits persisted in the dyslexia group. These findings support the causal role of phonological awareness in the acquisition of reading skills and indicate that differences in phonological processing skills are still evident in a sample of university students with dyslexia compared a group matched on age and education.

Bilateral primary ovarian squamous cell carcinoma associated with human papilloma virus infection and vulvar and cervical intraepithelial neoplasia. A case report with review of the literature.

Primary squamous cell carcinoma of the ovary is rare. Most cases represent malignant transformation of ovarian teratomas. Other cases are associated with preexisting Brenner tumor or ovarian endometriosis. We report a primary ovarian squamous cell carcinoma in a 40-year-old woman. The patient had recurrent high-grade intraepithelial neoplasia of the vulva (VIN) and recurrent high-grade cervical intraepithelial neoplasia (CIN). Human papilloma virus (HPV) DNA 16/18 was identified in an in situ and invasive carcinoma in the left ovary; CIN and VIN were identified with in situ hybridization with biotinylated DNA probes. Review of the literature revealed nine cases of primary ovarian squamous cell carcinoma not associated with a preexisting ovarian lesion. Three cases were not associated with CIN and occurred in women who ranged in age from 64 to 90 years and did not have carcinoma in situ component. Six cases were associated with CIN, had a carcinoma in situ, and occurred in younger women ranging from 33 to 54 of age. Our case belonged to the latter category. This report raises the possible causal relationship of HPV with primary ovarian squamous carcinoma in the group of middle-aged patients with CIN.
