[Surgery of duodenal ulcer. In decline?].

The authors report their experience of the surgical treatment of duodenal ulcer disease and its complications over a 10 year period (1976-1986), i.e. 336 cases from a group of 10748 digestive tract endoscopies performed and 1126 duodenal ulcers identified (10.4%). The efficacy of new types of medical treatment (anti-secretory drugs, endoscopic hemostasis techniques, prostaglandins) and the improved follow-up of patients tend, despite the value and proven safety of Parietal-cell Vagotomy (elective procedure in 76% of the group), to modify: the epidemiological aspect of the disease in the sense of a decrease in the rate of ulcers with complications related to stenosis and perforation; the therapeutic aspect with more limited surgical indications. Is this the end of surgery for duodenal ulcer and its complications?

[Application of a co-electrosyneresis reaction to the diagnosis and serological surveillance of candidiasis in a hospital milieu].

We have previously described a co-immunofiltration reaction which identifies a specific precipitating system (SPCS) in sera from patients presenting systemic candidiasis. The SPCS is characterized by coalescence with an experimental serum directed against the germinative tubes of Candida albicans. The present study concerns our experience of the use of co-immunofiltration in routine hospital practice. Complete observations involving clinical, mycological and serologic data were selected in order to illustrate various possible developmental trends for SPCS during candidiasis. The SPCS usually develops early infections due to the yeast species most frequently implicated in hospital pathologies; an increase in its intensity reflects a developing infection or the start of therapy. The SPCS disappears slowly and gradually when infectious development is favorable, but its sudden disappearance represents an unfavorable prognosis correlated with detection of circulating antigens. Circulating antigens are also seen in severe cases of candidiasis in which the SPCS is not present. Indeed there is a certain complementarity between these two observations.

[The lung in peritonitis. Contribution of data processing to the evaluation of pulmonary risk: practical conclusions].

A retrospective study of 99 case-reports of patients with generalized peritonitis, including 38 postoperative cases involving peritoneum and lungs, was conducted with the aid of two files based on documented data containing 168 and 204 analytical criteria respectively. Data processing and statistical analysis alone were capable of establishing possible relationships between isolated or associated peritoneal factors and respiratory manifestations. Out of the vast quantity of data obtained by using this new approach, only factors significantly affecting pulmonary complications were retained: some relations could not be established because of the small number of patients studied. Respiratory complications were frequent (60%) and severe (58% mortality). They occurred in 96% of postoperative peritonitis cases, with 77% of deaths, and in 44% of primary peritonitis cases, with 36% of deaths. In contrast, when absent the mortality is reduced to 4%. Frequency distribution of clinical signs, pulmonary radiological images and the effects of gasometry are analyzed. Obstruction is a frequent and early symptom. The presence of bilateral diffuse lung shadows and their shunt effect are narrowly correlated with the presence of postoperative peritonitis. Respiratory complications were correlated with peritonitis criteria, particularly with age, the sub-mesocolon origin of the peritonitis, the rapidity of operative intervention, and surgical excision rather than shunt formation or suturing, and to the development of criteria of repeat abdominal or extra-abdominal surgery. Initial antibiotherapy and digestive suction have, on the contrary, no effect. Many other criteria were studied. A "profit" of patients liable to develop these complication is described, the mechanisms outlined, and the means of prevention and of rapid detection discussed, particularly the important role played by early gasometry.

Road accident statistics: discrepancies between police and hospital data in a French island.

In most developed countries, information on road crashes are routinely collected by the police. However, comparison of police records and hospital data underlines a deficit of the number of road accidents in the routine statistics. In La Réunion, a French overseas dependency, an epidemiological study of injuries leading to hospitalisation or deaths has been performed from June 1993 to June 1994. The comparison between hospital data and police records showed that only 37.3% of non-fatally traffic-injured in-patients were recorded by the police. Length of stay in hospital, physician in charge of the first aid, urban place of the crash, type of vehicle involved, day and time of the crash and blood alcohol concentration were significantly associated with the presence in the police file. Police overestimated the severity of the injuries. Police notified 100 deaths on the 115 counted by the study. In France, non-fatally traffic-injured should be followed 30 days to improve quality of police death records. A capture-recapture method was used to estimate the total number of injured people. The capture-recapture method consists in merging information from several sources of notification to determine the real number of cases in the population and the exhaustivity of each source. We estimated that 346 subjects were injured in one month whereas police data recorded only 87 and hospital data 137. This method seems interesting to use in routine after validation when unique personal identifiers are available.

[African vesico-vaginal fistulas (author's transl)].

Obstetrical vesico-vaginal fistulas in Africa are very frequent and are correlated with the insufficiency or even the lack of health structures and sanitary conditions. They follow up a dystocic parturition, and their prevention requires a correct surveillance of pregnancy and parturition. Their pathogenesis consists in a durable compression of the pelvic cavity by the foetal head, inducing ischemia and later on necrosis. Their difficult treatment is based on clinical inspection which makes possible to distinguish several pathological types of fistulas. Surgical tactic will be selected according to the size of the fistula, the conservation or the destruction of the uretra with the vesico-uretral sphincters, the importance of perifistula sclerosis. BRACQUEHAYE'S operation is the basis of the conservatory treatment, associated or not with a technic restoring the urinary continence: either the INGELMAN-SUNDBERG operation of the LE GUYADER rectomyoplasty. When uretra is destroyed, the best palliative intervention is probably the building up of a rectal neobladder. These operations can be performed under conditions often prevailling in Africa. In most cases, they have restored normal social life for the women affected. But setbacks are not rare, and demonstrate the importance of prophylaxis.
