[Phenoperidine and operative common bile duct pressure (author's transl)].

The pressure variations registered in the common bile duct, after injection of phenoperidine (0,033 mg/kg) during sixteen anaesthesias performed for cholecystectomy, showed no significant modifications. In one case a spasm of the common bile duct was observed before analgesic administration which induced no change in the biliary pressure, an inhalation of amyl nitrite made it possible to affirm the functional character of the anomaly. The analgesic anaesthesia using phenoperidine, method chosen for high-risk patients, is compatible with bile duct surgery without risk of bringing about unnecessary surgical procedures.

Visual phenotype of multiple sclerosis in the Afro-Caribbean population and the influence of migration to metropolitan France.

PURPOSE: To describe the visual phenotype of multiple sclerosis (MS) in the Afro-Caribbean population living in Martinique (French West Indies) and to specify the influence of the migration to metropolitan France on ocular impairment. DESIGN: Prospective consecutive observational case series. METHODS: A complete ophthalmologic examination was performed. PARTICIPANTS: A total of 112 patients of Afro-Caribbean origin with MS satisfying McDonald's diagnostic criteria, divided into 53 cases (47.3%), the non-migrant patients (group NM), who had never left the Caribbean basin, and 59 cases (52.7%), the migrant patients (group M), who had lived in metropolitan France for at least 1 year before age 15. RESULTS: MS first manifested as an impairment of the optic nerve in 41 cases (36.6%): 25 cases (47.1%) in group NM and 16 cases (27.1%) in group M. Visual function was recovered in 13/25 cases (52%) in group NM compared to 13/16 cases (81%) in group M. Two-thirds of patients presented with a clinical ocular impairment, which was bilateral in 58.5% of cases in group NM. Fourteen cases (12.5%) met the criteria of neuromyelitis optica, nine cases (17%) in group NM and five cases (8.5%) in group M. In group NM, when the initial visual attack did not regress, the visual Expanded Disability Status Scale (EDSS) score was 5+/-1.5 ; 75% of patients had monocular blindness and 50% binocular. CONCLUSIONS: In the non-migrants (group NM), MS manifested more frequently with an optical neuropathy, the ocular impairment was more severe, and corresponded to neuromyelitis optica in 17% of the cases; a visual presentation and the absence of complete recovery from the first attack represented a factor of poor prognosis. This series is the largest description of the visual phenotype of MS in patients of African origin. The results confirm the preferential impairment of the optic nerve in the black population in the course of the disease. The migration towards an area of high prevalence of MS influences the visual phenotype in terms of a lower incidence and less severe prognosis of ocular impairment.

[Enteral feeding with reinjection in the terminal gut (author's transl)].

About one case, we describe our technology. The main avantage of the method is to reduce strongly septic complications resulting from intravenous feeding. It can be used as soon as the gastrointestinal tract is functional without any risk and it is the most effective means of providing nutrition for an extended period.

Isolated conjunctival ulcerations as the first sign of Behçet's disease.

PURPOSE: To report an unusual incident of isolated conjunctival ulcerations which preceded all other signs of Behçet's disease. METHODS: Description of a 34-year-old woman of West Indian origin with an unremarkable medical history presenting with bilateral bulbar conjunctival ulcerations. RESULTS: The authors noted the presence of a diffuse bilateral conjunctival hyperemia which was more pronounced at the temporal bulbar conjunctiva of the right eye and the nasal conjunctiva of the left eye, each having one ulceration. The rest of the ophthalmologic examination was normal. One month later, the appearance of buccogenital aphthosis led to the diagnosis of Behçet's disease. CONCLUSIONS: This observation is unusual, as the conjunctival ulcerations are isolated and precede the onset of all other symptoms of Behçet's disease. Conjunctival ulcerations are rarely seen with Behçet's disease, but are characteristic enough to be included among the diagnostic criteria.

[Therapy of chronic autonomous pancreatitis. Results in 147 cases (author's transl)].

The authors summarize their own personal experience acquired in the Department of Pr. Mercadier, concerning chronic pancreatitis. They attempt to define the factors influencing the choice of surgical technic, whilst emphasizing the grave nature of this condition, the long term prognosis of which remains severe in 50 per cent of cases.
