[Histiocytosis X and sclerosing cholangitis].

The case of a seven-year-old with multifocal (type II) Langheran's cell histiocytosis since the age of two years is reported. Despite therapy, biliary cirrhosis with portal hypertension developed gradually. Histologic studies of liver biopsy specimens, computed tomography, and transhepatic cholangiography disclosed dilatation of the bile ducts, suggesting sclerosing cholangitis, a specific complication of Langherans' cell histiocytosis which precipitates the development of biliary cirrhosis.

[Value of barium transit of the small intestine in research on Meckel's diverticulum].

Twelve children were diagnosed as having a bleeding Meckel diverticulum upon laparotomy. Before surgery, barium small bowel examination was performed according to the Bret technique (J Radiol Paris [1980] 61, 753-758) in 8 cases; the Meckel diverticulum being apparent in all 8 cases. By contrast, a classical technique of barium small bowel examination used in 4 cases, and 99m TC pertechnate scan performed in 7 cases, yielded only negative results. We conclude that barium small bowel examination, when performed according to the Bret's technique, is a very effective method for the diagnosis of Meckel diverticulum.

[Vaccination against hepatitis B virus].

More than 200 million people infected with hepatitis B virus worldwide, with high risk of developing hepatic disease ranging from chronic hepatitis to hepatocellular carcinoma, underline an imperative need for an efficacious vaccine. Many studies have provided repeated assurance on the safety and efficacy of hepatitis B vaccines derived from plasma pooled from carriers. However, alternative methods for vaccine production are necessary and DNA recombinant vaccines are currently available. Recombinant hepatitis B vaccines are safe, antigenic, and free from side effects. The immunogenicity of yeast hepatitis B vaccine is similar to that of the plasma-derived vaccine. In the mammalian recombinant vaccine, pre-S2 region is added to S region and should confer quicker and stronger efficacy in hepatitis B protection.

[Stenosing gastroduodenal ulcer in children. Apropos of 3 cases].

Three cases of stenosing peptic ulcers in young children (age 21 months, 6 years and 8 years) are reported. During infancy, peptic ulcer is the main cause of pyloric stenosis after pyloric hypertrophy. The stenosis reveals or complicates primary gastric or duodenal ulcers. A complete cure can only be obtained with medical treatment.

[Diagnosis and management of acute viral hepatitis in children].

In a child presenting with acute viral hepatitis, one must answer 3 questions: does it occur on a former liver disease? is it a fulminant hepatitis? which virus is responsible for the hepatitis and which preventive measures are necessary? The responses can be provided through clinical data and simple biological tests.

[Idiopathic retroperitoneal hematoma. Apropos of a case].

A 10 year-old girl presented with a progressive left ureteral colic with abdominal tenderness. Ultrasonography revealed pyelocalyceal dilatation and an intravenous pyelogram showed lateral deviation of the left ureter. Computed tomography confirmed retroperitoneal mass distinct from psoas. Laparotomy revealed an encapsulated retroperitoneal hematoma. No particular aetiology was found and the patient's health remained stable after treatment.

[Recurrent infections caused by Salmonella typhimurium].

We report the case of a 27 month-old girl with recurrent Salmonella typhi murium infections. The study of the neutrophil cells showed a transitory selective deficiency of the chemiluminescent response. After 5 months of pefloxacine therapy, recovery was obtained.

[Acid gastroesophageal reflux in the child with intubation, artificial respiration and continuous nutrition. Apropos of 28 cases].

Continuous monitoring of distal oesophageal pH and oesophagoscopy were performed in 28 children aged 15 days to 12 years (mean: 14 months) intubated and ventilated for bronchiolitis (7), pneumonia (8), epiglotitis (2), neurological distress (8), whooping cough (2) or recurrent apneic spells (1). Esophageal pH was studied 2-8 days (mean: 2 days) after intubation; its duration was 12-23 h 50 min (M: 22 h). An abnormal gastroesophageal reflux was presumed when the percent of total monitoring time during which the esophageal pH fell below 4.0 was above 5.2%. The esophagoscopy was carried out on the day following the pH monitoring. All children were in the supine position and fed a pH 7 diet infused continuously with a nasogastric tube; 15 children were under pancuronium. An abnormal gastroesophageal reflux was found in 4 children, associated with a benign esophagitis in 2. A benign esophagitis without gastroesophageal reflux was found in 3 cases. One child had a peptic ulcer of the bulb without gastroesophageal reflux nor oesophagitis. 21 children had no abnormality. Only one of the 15 children under pancuronium had an abnormal gastroesophageal reflux. We conclude that in intubated children fed continuously with a nasogastric tube, gastroesophageal reflux is unfrequent and, when present, appears to have little consequences.

[Metastatic neuroblastoma with secondary hypersecretion of vasoactive intestinal peptide].

A 18-month-old boy with stage 4 neuroblastoma needed intensive care because of prerenal acute renal failure related to an intractable watery diarrhoea syndrome occurring 10 months after the diagnosis of the primary tumor. This diarrhoea was in relation with a late hyperproduction of vasoactive intestinal peptide by the relapsing neuroblastoma itself and stopped with intravenous somatostatin administration.

[Transient dilatation of the intra- and extra-hepatic bile ducts. A new aspect of bile duct involvement in scarlet fever].

An extra- and intra-hepatic bile duct dilatation has been observed in a child in the course of scarlet fever. Manifestations of cholestasis, cytolysis and inflammation were present. Pruritus disappeared within 2 months, biological abnormalities within 3 months and ultrasonic bile duct abnormalities between 3 and 6 months, with a follow-up of 9 months. This case report suggests a relationship between a transitory obstruction, possibly toxic in origin, of the bile ducts and the scarlet fever.

[Congenital intrinsic factor deficiency. Apropos of 3 cases in a sibship].

Three familial cases of congenital intrinsic factor deficiency are reported: the stress is put on the interest of gastric investigations and especially of the quantity of intrinsic factor in the gastric juice when investigating megaloblastic anemia due to vitamin B12 deficiency. The study of the level of intrinsic factor in the gastric juice is proposed as a test for identifying carriers.
