[Apropos of 2 cases of severe malaria contracted in the port of Marseille].

Acute Plasmodium falciparum malaria occurred during summer 1993 in two inhabitants living close to Marseille harbour. History of blood transfusion and travel outside France were excluded as was also discarded airport malaria. Entomological investigations confirmed the absence of Anopheles breeding sites in the port area. An hypothesis is a vectorial transmission following introduction of one or several anopheles arrived on a ship coming from tropical Africa. During this season, the weather conditions were favourable to the survival of anopheles and the completion of P. falciparum sporogonic cycle. Physicians were advised to take into consideration malaria in the differential diagnosis of fever from unknown origin in any patient working or living inside or around the harbour area regardless history of previous travel in malaria endemic region.

Serologic evidence for human ehrlichiosis in Africa.

Human ehrlichiosis is a recently recognized rickettsial disease. It is caused by Ehrlichia chaffeensis, an intraleucocytic Gram-negative, obligate intracellular bacterium, grouped within the genus Ehrlichiae. Most human cases of ehrlichiosis have been diagnosed in the USA. Two cases have been reported outside of the USA, one in Europe and one in Africa. From 1 January to 30 June 1992, 765 sera from blood donors or other asymptomatic subjects in 8 African countries, including Ivory Coast, Burkina Faso, Mali, Central African Republic, Angola, Zimbabwe, Mozambique and Commores Islands, were tested by indirect immunofluorescence for the presence of E. chaffeensis antibodies. Positive sera were confirmed by Western immunoblotting. Only two of 765 sera tested were positive. One serum obtained from Burkina Faso had an IgG titer of 1:200 and one from Mozambique had an IgG titer of 1:80. Human ehrlichiosis seems to occur infrequently in Africa, although many more sera from additional African countries need to be evaluated.

Endoscopic sphincterotomy for common bile duct calculi in patients without stones in the gallbladder.

Endoscopic sphincterotomy (ES) was performed in 25 patients for common bile duct (CBD) calculi in the absence of stones in the gallbladder. Eighteen of these patients were considered unfit for surgery because of age or concomitant disease. All ES procedures were technically successful with complete evacuation of the CBD in all cases. Early complications occurred in only one patient, a 91-year-old female who died from nonbiliary tract disease. Long-term follow up over a period of 42 months was available in 19 of the 24 patients. Late complications occurred in two patients (10%), both of whom developed cholecystitis; they underwent surgery without subsequent morbidity or mortality. This 10% incidence of long-term complications is similar to that of other series that did not differentiate between patients with isolated CBD calculi and those with stones also present in the gallbladder. The observed complication rate does not justify routine prophylactic cholecystectomy after ES for isolated CBD stones.

Cholescintigraphic study of effect of somatostatin analog, octreotide, on bile secretion and gallbladder emptying in normal subjects.

The objective of the study was to investigate the effects of a single intravenous injection of the somatostatin analog octreotide on hepatic bile secretion and gallbladder emptying with a quantitative scintigraphic technique. Twelve healthy volunteers received, in a double-blind randomized fashion, either octreotide, 100 micrograms intravenously, or placebo. Ten minutes later, [99mTc]PBIDA was administered intravenously (50 microCi/kg) (time = 0) followed, 60 min later, by the ingestion of a standardized fatty meal. In the liver area, the relative decrease per minute of tracer activity from the time of maximal activity to 60 min was significantly lower in the octreotide group (P = 0.02). In the gallbladder area, after the fatty meal, the ratio of tracer activity at 60 and 90 min (A90/A60) was significantly (P = 0.01) higher in the octreotide group. Our study demonstrates that octreotide slows down liver release of the radiopharmaceutical, probably reflecting decreased bile secretion, and inhibits postprandial gallbladder contraction.
