[Endoscopic management for hepatic duct injury in children].

Non-operative management of hepatic injury in children with abdominal trauma represents a standard of care. A major duct injury with persistent bile leakage may result from trauma to the liver. This injury is of concern in patients treated non operatively because it generally requires major hepatic surgery. We report on a case of a 13-year-old boy with an hepatic duct injury from trauma in which healing occurred without surgical repair or resection.

[Macrocephaly and multiple hamartoma: a very variable entity].

UNLABELLED: The Bannayan-Zonana is a dominant autosomal polymalformation syndrome. CASE REPORT: We report a case of Bannayan-Zonana syndrome in a 3-year-old girl, who presented with macrocephaly and a cervical lipoma. The patient's mother had neurofibromatosis I. No mutation in the PTEN gene was found. The slowly progressive lipoma increased with age and the surgical reduction was necessary. COMMENTARIES: Macrocephaly is constant in different syndromes characterized with multiple hamartomas. The multiple hamartomas syndrome represents an entity with a high variability of expression.

[Intrauterine intussusception causing intestinal atresia during pregnancy].

CASE REPORT: A case of intrauterine intussusception causing ileal atresia is reported. The neonate presented at the age of one day with bilious vomiting, failure to pass meconium and progressive abdominal distension. A clinical diagnosis of intestinal obstruction was made, and was confirmed by plain abdominal radiographs. At laparotomy, atresia of the terminal ileum was found. The lumen of the resected distal segment contained an intussusceptum. The blind ends were resected and an anastomosis was performed. Recovery was uneventful. COMMENTS: Intrauterine bowel intussusception is a rare clinical entity. When intussusception occurs in the foetus and the time elapsed is enough to allow for gangrene and resorption of the intussuscepted portions of the bowel, intestinal atresia may result. CONCLUSIONS: The careful examination of the distal blind end of the ileum aids to obtain a correct classification and etiologic diagnosis of the atresia.

[Cowden's disease in an adolescent].

Cowden's disease is an autosomal dominantly inherited syndrome characterized by mucocutaneous lesions and multiple hamartomas. We report here a 12 years-old boy case with craniomegally, intestinal polyps, epilepsy and multiadenomatous goiter. All the lesions were beginnings. The predisposing genetic defect has been assignated to chromosomal 10 (PTEN-gene mutation). A long term follow-up is necessary because of the risk of malignancies.

[Early repair for infants with cleft lip. Retrospective study of 263 cleft lip repairs].

This study attempts to define the effect of early repair on the surgical procedure and immediate outcome of cleft lip surgery. The first part deals with 263 consecutive cleft lip repairs (218 infants) categorized retrospectively by age at operation. 123 patients (150 cleft lips) were operated on during the first 4 weeks of life; a subgroup of 40 infants was operated on at a week or less of age; 95 patients (113 cleft lips) were operated at an older age (1 to 12 months). There were no significant difference in immediate surgical result between the groups and there was no apparent difference in the operative results as defined by whether or not the child needed subsequent revision. We are currently encouraging early repair in the full-term baby as the optimum method of management of newborns with cleft lip.

[Johanson-Blizzard syndrome: a case report].

UNLABELLED: The Johanson-Blizzard syndrome is a rare autosomal recessive syndrome. This syndrome includes congenital aplasia of the cutis, aplasia of the alae nasi, bilateral hearing loss, dental malformations and pancreatic insufficiency. CASE REPORT: We report a sporadic case male infant from nonconsanguineous parents. He presented aplasia of the cutis and high anorectal malformation, associated with exocrine pancreatic insufficiency. A colostomy was performed at birth and anorectal atresia was corrected surgically at two months. Exocrine pancreatic insufficiency required immediate enzyme supplementation.

Treatment of facial dog bite injuries in children: a retrospective study.

PURPOSE: The authors assess their approach to immediate surgical repair with general anesthesia of facial dog bites in children over a 10-year period in their pediatric department. METHODS: The authors reviewed a series of 100 children (59 boys, 41 girls) who required immediate surgical intervention during the first hours after admission between 1985 and 1995. Strict disinfection was always used to preclude the risk of rabies, and parenteral antibiotherapy was used to avoid aero-anaerobic infections. RESULTS: A total of 68% of children were below 5 years of age. The most frequent injury was to the midface. Associated injuries or death were not observed. One case of postoperative wound infection was noted. Four surgical revisions were performed because of unsightly scars, but in most children the scar had attenuated 1 year after injury. CONCLUSIONS: The aim of immediate surgical repair is to obtain a satisfactory cosmetic result and to avoid infections. Better cosmetic results (4 cases of scar revisions) with a minimal risk of wound infections (1 cheek wound infection) are obtained.

Phagocytic reaction in contact with macroplastic: application in pediatric surgery.

BACKGROUND/PURPOSE: With regard to the problems of using polytetrafluoroethylene (PTFE) in the treatment of vesicoureteric reflux in children, the authors have tested polydimethylsiloxane (PDMS), which is conveyed by polyvinylpyrrolidone (PVP), a hydrogel. METHODS: The phagocytic reaction was tested with both PDMS and PVP. The phagocytic reaction of PDMS and PVP was tested in vitro, then the outcome of PVP was tested in vivo in the mouse. RESULTS: In vitro PVP was phagocytosed by mouse peritoneal macrophages. However, PDMS particles were not phagocytosed because of their large size. In vivo, PVP migrated to other organs but did not induce clear histologic lesions. CONCLUSIONS: Silicone (PDMS) has been used in the treatment of vesicoureteric reflux in children. It is now necessary to do tests on heavier animals with a long incubation period to know whether these particles migrate and what the histologic and clinical consequences might be.

[Cleft lip and palate. Epidemiologic analysis: report of 60 cases].

The authors reviewed 60 cases of cleft lip and palate between November 1996 and May 1998. Any family history of cleft lip and palate and associated syndromes was noted, to detect a possible mode of transmission. A family history of cleft lip and palate was reported in 14 cases (23%). Possible autosomal dominant transmission was observed in this series. A syndromic form was observed in eight cases (13%), with one case of Van der Woude's Syndrome (VWS), and another of velo-cardiofacial Syndrome (VCFS). Molecular and chromosomal studies are indicated in both cases. A Pierre Robin sequence (PRS) was found in six cases.
