[When diagnostic imaging is misleading: a case of subacute liver failure]. / LE CAS CLINIQUE DU MOIS. Quand l'imagerie nous induit en erreur: à propos d'un cas d'insuffisance hépatique subaiguë.

We report the case of a 67 year old woman presenting with a mixed alteration of liver function tests. Despite normal results of tomodensitometry and positon emission tomography, a liver biopsy was performed due to the development of acute liver failure: it showed a diffuse infiltration of liver sinusoids by a breast adenocarcinoma, unfortunately fatal for the patient. The tumour infiltration was responsible for portal hypertension and hepatic perfusion disorders leading to liver failure.

[A case of hypernatremic dehydration due to breast-feeding]. / Déshydratation hypernatrémique au cours d'un allaitement maternel.

The authors report an 11-day-old exclusively breast-fed female, with a birth weight of 3 300 g, who had suffered from dehydration stage I, with acute renal failure and metabolic acidosis, with 170 mmol/L of serum sodium. Renal ultrasounds were normal but the rate of sodium in mother's milk was three times higher than controls (87 versus 21 mmol/L). Intravenous rehydration allowed the correction of hydroelectrolytic disorders.

[Duplicate principal bile ducts. Two case reports]. / Duplicité de la voie biliaire principale. A propos de deux cas.

The duplicity of the way biliaire main is a rare abnormality. We report two observations revealed by episodes of angiocholite. The degrades cholangiopancreatography endoscopy allowed to wear diagnosis and to practise a therapeutic gesture.

[Detection of hepatitis C virus in the general population of Tunisia]. / Dépistage de l'hépatite virale C dans la population générale en Tunisie.

We searched for antibodies to hepatitis C in a sample of 3079 Tunisians in the suburban area of Tunis. 30 people were positive by ELISA and 22 were confirmed by immunoblotting. This result represents a prevalence of 0.71% which is close to the values reported in European countries of the Mediterranean area.

[Extra-adrenal gland pheochromocytoma. Apropos of 3 cases and review of the literature]. / Le phéochromocytome extrasurrénalien. A propos de trois observations et revue de la littérature.

The authors report three new cases of ectopic pheochromocytoma: latero-aortic, bladder and near the kidney. From the review of the literature, they propose a diagnostic and therapeutic strategy for the management of ectopic localisation of pheochromocytoma.

[Adrenal myelolipoma]. / Le myélolipome surrénalien.

The authors report a case of myelolipoma discovered in a 57 year-old woman by ultrasonography and computed tomography. The tumour was 10 cm in diameter and weighed 350 grams. This case is discussed in the light of a review of the literature.

Hepatitis C core antibody detection in acute hepatitis and cirrhosis patients from Tunisia.

The detection of anti-Hepatitis C virus (HCV) Core antibodies is an important addition to HCV antibody testing. In this study it appears to be more specific than the first generation HCV tests and in combination with the detection of anti-C33c antibodies, it is possibly more sensitive. In Tunisia hepatitis C virus is implicated by the presence of anti-Core antibodies in only 8% of the adult cases of acute hepatitis as opposed to 60% for Hepatitis B virus (HBV) and 4% for Hepatitis A virus (HAV). In contrast to the low prevalence of HCV infection among acute hepatitis cases, HCV infection is implicated in 35% of the cirrhosis cases. These results stress the potential importance of HCV infection in the development of cirrhosis which is a relatively common disease in North Africa.
