Pseudomonas aeruginosa liver abscesses following endoscopic retrograde cholangiography. Report of a case without biliary tract disease.

We report a case of Pseudomonas aeruginosa liver abscesses following endoscopic retrograde cholangiopancreatography (ERCP) in a patient without evidence of biliary tract disease and of any known cause of hepatic infection. Computer tomography (CT) scan was the best method of diagnosis, allowing, through guided percutaneous puncture of the abscesses, isolation of the organism, which was sensitive to carbenicillin. One month of antibiotherapy with repeated aspirations of the largest abscesses was successful. This report suggests that ERCP may induce cholangitic sepsis by inoculating pathogens in the biliary tree even in the absence of extrahepatic obstruction.

[Hepatic brucelloma (pseudotumoral brucellar caseous necrosis of the liver). Study of a case and review of the literature].

We report the case of a 43 year-old Portuguese woman, hospitalized for long-standing fever, fatigue and weight-loss. Biologic investigation demonstrated anicteric cholestasis. Abdominal plain film showed a single hepatic calcification; computerized tomography and ultrasonography of the liver led to the discovery of a large mass, centered by the calcification. C. T.-guided biopsy showed caseiform necrosis, surrounded by histiocytic and lymphocytic cells. Brucella agglutination tests were negative at the beginning of the illness but became positive secondarily. The germ was not isolated from the hepatic fragment. The melitine intradermo-reaction was positive. Outcome was rapidly favorable with antibiotic treatment. Analysis of the 14 previously published cases showed that the most constant features were the hepatic calcifications and the epidemiologic context.

[Acute hepatitis due to carbamazepine (Tegretol). Study of a case and review of the literature].

The case of a 28-year-old epileptic woman, treated for 3 months with carbamazepine and who developed jaundice, fever and exfoliative dermatitis is reported. Biological investigations showed an increase in the activity of serum transaminases and alkaline phosphatases as well as in the blood eosinophilic count. Liver biopsy revealed centrolobular necrosis and cholestasis with portal inflammatory infiltrate. Drug challenge was followed by the rapid recurrence of clinical and biological signs. The definitive outcome was favorable. The analysis of the 12 previously published cases, and particularly the frequency of granulomatous hepatitis, suggests an immunoallergic mechanism for the development of carbamazepine hepatitis.

MR imaging of CNS relapse of Whipple disease.

We report a case of late CNS relapse of Whipple disease without articular or digestive signs. Magnetic resonance (MR) imaging of the brain clearly showed the disappearance of the normal low intensity signal of the aqueduct of Sylvius and the presence of high intensity signals in the frontal white matter and in the caudate nucleus. This case suggests that MR imaging of the brain is the procedure of choice for identifying cerebral involvement in Whipple disease.

[Cyclic enteral nutrition and Crohn's disease localized in the distal ileum and/or the colon. Trial of a dietary polymer mixture].

UNLABELLED: Cyclic enteral nutrition (CEN) is a technique regularly used during the active phases of CDIC. Elemental or semi-elemental diets are usually employed. We tested the tolerance and efficacy of a ternary polymeric diet for nightly administration on a discontinuous basis (Polydiet). CEN was given to 12 malnourished patients with active CDIC of moderate intensity (6-9 Harvey Bradshaw Index). Corticosteroid therapy with prednisolone (0.3 to 0.9 mg/kg) was given in combination in 6 patients throughout the course of CEN. Duration of CEN, energy and protein intake, age, sex, degree of activity of CDIC and lesional extent, and percentage of malnutrition were comparable in both groups of patients. In all cases, clinical tolerance was remarkable allowing therapy to be maintained. No significant change in laboratory test values of hepatic or renal functions or of plasma lipids occurred. A positive significant variation was noted in both groups for the following parameters: body weight (p less than 0.01); muscle circumference (p less than 0.001); serum albumin (p less than 0.001), transferrin (p less than 0.01), clinical score (p less than 0.001). Triceps skin fold and lymphocyte count did not vary significantly. Corticosteroid therapy at the above dosage did not alter these parameters. Positive maintenance of nitrogen balance was obtained in all cases at the end of the first week of CEN. CONCLUSION: With equivalent nutritional value and for a lower cost, polymeric diets could be used more frequently in the treatment of CDIC. Tolerance and correction of nutritional disorders appear comparable to elemental products if lesions affect only the distal small intestine and/or colon.

[Ganglio-esophageal fistula revealed by hematemesis: a rare complication of silicotuberculosis].

We report a case of fistula between a silicotic mediastinal lymph node and the esophagus with protrusion of a stiff and darkish concretion into the oesophageal lumen. The patient, a 68-year-old coal miner, presented with cough since a few months and the lesion was revealed by haematemesis. The general course was rapidly favourable. Association with tuberculosis was recognized only a few months later.
