[Ehlers-Danlos syndrome associated with acute pancreatitis].

Ehlers-Danlos syndrome is an inherited connective tissue disease characterized by articular laxity, hyperelastic skin and tissue fragility. The syndrome is genetically, biochemically and clinically heterogeneous and several well-defined subtypes have been identified. We describe a patient with the type IV variant of this syndrome who developed acute spontaneous pancreatitis.

AIDS-associated cholangiopathy in a series of ten patients.

OBJECTIVE: To present the clinical, biological, radiologic and cholangiographic findings in patients with clinical suspicion of AIDS associated cholangiopathy in our hospital. PATIENTS AND METHODS: We have revised the clinical charts of 10 patients admitted in our hospital from 1991 to 1995. RESULTS: Ultrasonography and/or abdominal CT were carried out on all the patients. Biliary tract dilatation was observed in 11 cases. From the 12 ERCP, biliary tract was fulfilled in 11. In 5 cases papillary stenosis was diagnosed, sclerosing cholangitis in 2, normal biliary tract in 3 and acute cholangitis in one case. Sphincterotomy was done in 5 patients, with clinical improvement. In one case, another sphincterotomy was needed because of reestenosis. CONCLUSIONS: ERCP is very important in the diagnosis of AIDS associated cholangiopathy. Endoscopic sphincterotomy relieves abdominal pain in these patients. Cholangiopathy occurs in very immunocompromised HIV positive patients. Survival is very short.

Treatment of achalasia with botulinum toxin.

UNLABELLED: We studied the efficacy of local injections of botulinum toxin in the treatment of patients with achalasia. Four patients diagnosed of achalasia using manometric, radiologic and endoscopic criteria, were treated with botulinum toxin (80 U) injected directly into lower esophageal sphincter (LES), via a sclerotherapy injector. Response to treatment was assessed by changes in symptom scores and LES pressure. All determinations were repeated after 10, 30, 90, 120 and 180 days of treatment. The patients improved after the initial injection. This improvement was accompanied by improved relaxation of the LES. Two patients relapsed after 30 and 65 days and the other two patients remained symptom-free 5 months after treatment. CONCLUSION: Botulinum toxin is probably a safe and effective alternative for the treatment of achalasia and should be considered in patients in whom pneumatic dilation has failed or who are poor surgical candidates. Long-term evaluation of the safety and efficacy of botulinum toxin in the treatment of achalasia is required.

[Primary herpetic esophageal infection in an immunocompetent patient].

Herpetic esophageal primary infection is not a common event in immunocompetent patients. The case of a 27-year-old immunocompetent woman who developed herpetic esophagitis involving the whole esophagus as a manifestation of primary herpetic infection is presented. The endoscopic appearance initially suggested esophageal candidiasis, which is not an exceptional event.

[Gastrointestinal hemorrhage secondary to heterotopic jejunal pancreas].

A case of heterotopic pancreas located in the small intestine is herewith presented. The 19-years male patient had been admitted three times since 1991 for an anemic syndrome secondary to melena. The origin of the hemorrhage was not determined with the studies performed (intestinal transit, opaque enema, esophagogastroscopy, colonoscopy and gammagraphy with technetium 99). On the last admission a vascular lesion low flow was observed on arteriography of the upper mesenteric artery on the mesenteric edge of the proximal jejunum. Following laparotomy a small tumor was found in the jejunum and 5 cm of the intestine including the tumor was resected. The anatomic pathologic results demonstrated a heterotopic pancreas.

[Choledochal obstruction due to Fasciola hepatica (author's transl)].

A 45-year-old woman was admitted in July, 1976 with an acute cholecystitis without jaundice. She had suffered from hepatic colic without fever, jaundice, diarrhea or allergic episodes for the past 8 years. The physical examination only revealed an elective pain on the cystic point. Laboratory data were unremarkable, except for a 12 percent eosinophils. The cholecystogram showed a cholelithiasis. The lithiasis was confirmed during the surgical operation and a fasciolasis was diagnosed after one and 10-12 parasites had been found into the cystic and common bile duct, respectively. A cholecistectomy and choledochoduodenostomy were performed. The patient was treated with 60 mg dehydroemetine during 10 days and 500 mg chloroquine during the other next 10 days. Eggs of Fasciola hepatica were found in the stool culture. The follow-up examinations 3 months and a year after surgery were completely normal. The national literature on this topic is reviewed and the clinical manifestations and therapy of this disease are commented on.
