Acute acalculous cholecystitis due to Vibrio cholerae.

The case of a 57-year-old woman admitted with symptoms and signs suggesting an intestinal infection caused by Vibrio cholerae, and who also developed a clinical picture compatible with acute cholecystitis, is presented. Cholera was diagnosed by examining a fresh sample of stools and cultures. An abdominal sonogram disclosed signs of acute acalculous cholecystitis. She underwent cholecystectomy, and cultures of a clear fluid and a "milky" sediment found within the gallbladder were also positive for V. cholerae. This microorganism was seen at the gallbladder mucosa microscopically. The strain was serotyped V. cholerae 01 (El Tor) Ogawa and was the etiology of the acute acalculous cholecystitis in this patient.

[Familial multiple polyposis].

The familial multiple polyposis is a hereditary disease, autosomic, dominant, heterocigotous, not bound with sex and usually develops with puberty. If the patients are not treated at time, they will develops irremediably a cancer. We must build a pedigree and all the family members have to be investigated. This disease can be associated with other types of tumors and they are present concomitant with this polyposis, preceding it or appearing posteriorly, so, if we find one of these pathologies, we have to investigate the others. The treatment can be a proctocolectomy with permanent ileostomy or with rectum conservation and ileorectal or low ileosigmoid anastomosis with extirpation and fulguration of the rectal polyps before the colectomy or after it depending of the circumstances. They should have an endoscopic control of the preserved rectum each three months.

Ultrasound in the diagnosis of roundworms in gallbladder and common bile duct. Report of four cases.

Four patients who complained of symptoms and signs compatible with biliary tract disease and in whom the diagnosis of gallbladder (three cases) and common bile duct ascariasis (one case) was made sonographically are reported. In two patients with gallbladder ascariasis, cholecystectomy corroborated the presence of the round-worms, and was curative. The third patient was a pregnant woman (32nd gestational week) who took piperazine citrate, and a second sonogram performed 29 days later was completely normal. The fourth patient with common bile duct ascariasis underwent choledochotomy with extraction of one ascaris lumbricoides from the common duct, and a T tube was left in place for 15 days. All patients received antiparasitics and had a favorable outcome. Ultrasonography is an important noninvasive diagnostic procedure in the work-up of these patients, who usually describe a clinical picture suggesting gallstone disease: this is especially true in the presence of pregnancy.
