[Nosocomial respiratory infection due to an imipenem-resistant Pseudomonas aeruginosa O: 12 strain in a Tunis's neonatal intensive care unit].

OBJECTIVE: Investigation of an outbreak caused by an imipenem-resistant Pseudomonas aeruginosa strain and research of its hospital reservoir. PATIENTS AND METHODS: Nine strains isolated from protected tracheal specimens during 14 weeks (October 2004 to January 2005) from 8 infants, and one strain from vacuum interrupter were studied. Epidemiological study was investigated by determination of antibiotics susceptibility, serotyping and Pulsed-field gel electrophoresis (PFGE). RESULTS: Strains were of O:12 serotype, they have the same antibiotype characterised by imipenem resistance. Strains were indistinguishable or closely related as determined by PFGE. The common source of P. aeruginosa O:12 strains was not determined, however eradication of the epidemic strain was obtained by amelioration of hygiene conditions and the change of disinfectors. CONCLUSION: Outbreak of respiratory infections due to an imipenem-resistant P. aeruginosa O:12. The common source of the epidemic strain was not determined.

[Diagnosis of holoprosencephalia. Report of 17 cases].

OBJECTIVE: To establish the epidemiologic profile of holoprosencephalia and determine benefits of ultrasound and foetopathologic examination to the diagnostic. METHODS AN MATERIAL: [corrected] Retrospective study about 17 cases of holoprosencephalia observed in CMNT between Janaury 1992 and September 2000. RESULTS: Ultrasound diagnosis was made in 13 cases (75%). Ultrasound criteria were; absence of median structure of the brain and unique ventricule. The prognosis was always bad. Foetopathologic examination revealed 7 cases of lobar holoproencephalia and 10 of semi lobar. Fascial dysmorphia were noted in 82% of cases. CONCLUSION: The foetopathology and genetic counselling looking for fascial, dysmorphia in family's members gives a good evaluation of recurrences.

[Prolonged pregnancy: apropos of a series of 102 cases].

UNLABELLED: It was a retrospective and continuous prospective study about 102 post-term pregnancy recensed on a 14 months period. The aim of this study is to evaluate our management of post term pregnancy and the peto-maternal morbidity and mortality. RESULTS: Frequency of post-term pregnancy in our study is 5.92%, in rate of session sector is not higher it is of 18.62. There is no maternal mortality. Neonatal mortality is a about 19/1000, the rate of neonatal morbidity is 2.9%.

[Fetal pathology study of 88 cases of letal spina bifida].

Lethal spina bifida continue to be frequent in Tunisia; we report 88 cases of letal spina bifida: 1.05 per thousand births. This pathology was more frequent with women. The up letal spina bifida situated is predominant with female and the dow spina bifida situated is frequent with male. We have noted an association with anencephalia (46 cases) and hydrocephaly (21 cases). Prevention is based on obstetric health care and hygiene dietetic advices to avoid alimentary deficit.

The Antley-Bixler syndrome. A new case without radiohumeral synostosis.

The author report a new case of the syndrome described by Antley and Bixler. It concerns a female new-born who presents a craniosynostosis with brachycephaly, midface hypoplasia, unilateral choanal atresia, multiple joint contractures and arachnodactyly. There was no bowing of the femora and only the radius and the ulna were bowed. The absence of radiohumeral synostosis reported in all observations of the literature represents the main particularity of this observation.

Familial clustering of hepatitis B virus infections and prevention of perinatal transmission by immunization with a reduced number of doses in an area of intermediate endemicity (Tunisia).

Hepatitis B surface antigen (HBsAg) was detected in 3.3% of 7162 pregnant Tunisian women tested and HBeAg in 9.6% of the HBsAg-positive mothers. Family members of 46 of these HBsAg-positive mothers (33 husbands and 61 children aged 1-6 years) were investigated for the presence of HBV markers. HBsAg was detected in 21% of the children and 18% of the husbands. Fifty children born to HBsAg-positive mothers received hepatitis B vaccine at birth, at the age of 2-3 months and at the age of 9 months. After immunization, anti-HBs were detected in 92% of them with an anti-HBs geometric mean titre of 415 mIU ml-1. Compared with the HBsAg carrier state in older siblings, the protective efficacy was estimated to be 60%. It was 100% for infants born to HBeAg-negative mothers, but only 31% for those born to HBeAg-positive mothers. For a better efficacy, the schedule of the EPI needs to be modified to include an immunization session at 1 month of age.

[Congenital fibrolipoma of the mesencephalic protuberation area].

BACKGROUND: Congenital origin of brain fibrolipoma is still debated. A case of such a tumor is presented. CASE REPORT: A female newborn presented with severe hypotonia and macrocephaly that were seen since birth. She died at the age of 2 days. Post-mortem examination showed hydrocephaly due to a tumor located in the mesencephalo-protuberantial region. Histological features of this tumor were those of a fibrolipoma. CONCLUSION: The presence of this brainstem tumor at birth confirms its congenital origin.

[Wolman disease].

BACKGROUND: Wolman disease is a severe disease associated with hepatosplenomegaly and adrenal calcifications; it is nearly always fatal in the first year of life. CASE REPORT: A boy was born to consanguineous parents. His weight was 3,500 g, height 53 cm. Hepatomegaly was observed at the age of 26 days; he also had vomiting and watery stools with failure to thrive. Diagnosis of Wolman disease was suspected due to family history. Two sisters had died at the age of 3 months without precise diagnosis; both had abdominal distension, hepatosplenomegaly, anemia and inanition; CT scan showed calcifications of adrenal glands in one of them that had been attributed to adrenal hemorrhage. Investigations in our patient showed no adrenal calcification, hepatomegaly without splenomegaly, anemia (Hb: 8 g/100 ml). Liver biopsy showed enlarged and vacuolated parenchymal and Kupffer cells but the marrow did not contain foam cells. Acid lipase deficiency was demonstrated in cultured skin fibroblasts, permitting prenatal diagnosis in a further sib. CONCLUSION: This case of Wolman disease was the first seen in Tunisia; it was inherited as an autosomal recessive disorder; this patient, as two of his sisters, died during the first 6 months of life.
