Streptococcus B meningitis in post-partum.

We report a case of post-partum meningitis due to group B-streptococcus developing 24 h after vaginal delivery. Diagnosis was established by latex agglutination of streptococcus B-antigenes and confirmed by cerebrospinal fluid-culture later on. Clinical and haematological signs of meningitis disappeared after treatment with ampicillin. In a review of the literature we found eight other cases of streptococcal post-partum meningitis. In all of these cases, delivery was vaginal and no antibioprophylaxis was given.

Clinical biological features of Ballantyne syndrome and the role of placental hydrops.

Ballantyne syndrome was first described in association with severe hydrops fetalis caused by rhesus isoimmunization, and lately, in association with diverse etiologies of nonimmunological severe fetal hydrops. This report is a case of typical Ballantyne syndrome in association with lethal hydrops fetalis caused by Ebstein's anomaly. It is likely that any severe fetal hydrops with massive placental hydrops may produce Ballantyne syndrome. Hemodilution could be the main biological feature, differentiating Ballantyne syndrome from usual preeclamptic syndromes. Pathophysiological hypotheses are discussed.

Adult respiratory distress syndrome and pancytopenia associated with miliary tuberculosis in a HIV-infected patient.

Adult respiratory distress syndrome (ARDS) is a rare but severe complication of miliary tuberculosis, which may appear even after introduction of antituberculosis therapy. Mortality has been reported to be as high as 100% if there is associated pancytopenia. We report a case of a patient infected with the human immunodeficiency virus who presented with miliary tuberculosis associated with pancytopenia and adult respiratory distress syndrome.

Cerebral arterial disturbances in a transient encephalopathy induced by methotrexate.

The mechanism of the transient encephalopathy induced by high dose systemic administration of methotrexate (HDMTX) is unknown. Metabolic and vascular hypothesis have been formulated but convincing evidence is lacking. We report the first case of vascular disturbances (thinness of cortical arteries on angiography, reversible fall down of cerebral flow and increase of carotid resistance) in a young Algerian patient treated for an osteogenic osteosarcoma. This observation might lead to the exploration by non invasive and easily repeatable techniques of the cerebral vascular dynamic in patients submitted to HDMTX and thus contributed to the elucidation of the mechanism and to the prevention of these neurological side effect.
