Descriptive analysis of a series of operations for prostatic adenomas in inhabitants of Lyon, France, in 1988. Urological College of Lyon.

A retrospective, population-based study was conducted in Lyon, France, to elucidate the benefits and risks of a treatment for prostatic adenoma (benign prostatic hyperplasia). Case records were reviewed for all prostatectomies performed on patients in Lyon in 1988 for benign prostatic hyperplasia. Data were obtained from all records of public and private hospitals. Of 408 procedures, 312 involved endourethral resection (transurethral resection) and 96 open surgery. The mean weight of resected tissue was 20.3 +/- 0.9 g after endourethral resection and 71.7 +/- 6.4 g after open surgery. About 20% of the resections took place in a university hospital center, 43% in a not-for-profit private hospital, and 37% in a private clinic; there were eight deaths in the first 3 postoperative months, and 11 patients required hospitalization for urologic complications. Length of hospital stay uniquely correlated with age and type of surgery.

[The Lyons Hypertension Control Program (1972-1978). Community analysis].

A Community Control Program of Hypertension was undertaken in Lyon, as part of a WHO program. It dealed with two occupational, Study (S) and Reference (R), communities, each amounting to about 12,500 subjects. Its goal was to improve the level of treatment of hypertension in S, by stimulating the usual health care system without modifying it. It began in 1972 by a baseline total survey of both communities. Its aim was to check that the percentage of treated hypertensive subjects (HT) was the same in S and R (respectively 10.9% and 11.7%, n.s.), and to detect all HT's (subject being given an antihypertensive drug treatment, and/or BP greater than or equal to 160 and/or 94, or greater than or equal to 150 and/or 90 before age 30). The S intervention involved: detection of "new HT's" during the whole program; information of HT's, and referral to the treating physician of their choice, who was informed about the aim of the program and received later periodic information about hypertension management; periodic follow-up reconvocations. A leaflet including advices for C-V prevention was distributed to the whole S community in 1976. Evaluation was performed by a terminal total survey of both communities, from 1977 to 6/1978 (examination rates: 94.4 and 91.6% in S and R). The evaluation involved two analysis of 1977 data. -Cohort analysis (reported before): the percentage of treated HT's in the cohorts of 1972 HT's, still present in the community and hypertensive, was higher in S (63.0) than in R (46.1) (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

[The educated societies and the development of medical evaluation].

The French National Agency for Medical Evaluation (ANDEM) is regularly cooperating with scientific societies. In 1995, for the clinical guidelines and medical references program, ANDEM sent a request to 167 scientific societies. Societies were asked to select topics in which they had an involvement, to provide their guidelines, or recommendations they published, and to provide experts' names. 73 (44%) out of 167 scientific societies answered: 53 (77%) out of the 73 proposed themes, 20 (27%) sent a documentation, and 53 (73%) provided experts' names. Twenty (27%) out of the 73 wished to cooperate with ANDEM to draft clinical guidelines. Thirty (41%) out of the 73 gave a similar answer with less information. Twelve wished to cooperate but did not show any evidence for such a goal. The answering lag time, the presence of scientific society headings on the letter, the absence of arguments against the request showed that some scientific societies were better organized. It seems that many scientific societies did not have a good organization to efficiently answer to ANDEM request; they have not sufficient resources to afford all their objectives. Learned societies are not well defined, and their functioning is unknown. They wish to be recognized by professionals, institutions and all organizations. The scientific production does not seem to be much developed, even if such production is their first objective.
