[Rendu Osler disease revealed by ruptured cerebral arterial aneurysm in an infant]. / Maladie de Rendu-Osler révélée par la rupture d'un anévrysme artériel cérébral chez un nourrisson.

A 6 week-old boy whose mother and sister present with hereditary hemorrhagic telangiectasia (HHT) presented suddenly with listlessness, hypotonia, and acute anemia. Cerebrospinal fluid was grossly hemorrhagic. Brain CT scan was compatible with subarachnoid and intracerebral hemorrhage. Operative investigation diagnosed a ruptured aneurysm of one branch of the right middle cerebral artery. A large clot was removed from the right frontal lobe. The ruptured artery was clipped. Further cerebral and abdominal angiographies did not show other aneurysms. The infant died 18 days later, with bilateral subdural hematoma. The family history and review of the literature suggest that the rupture of a cerebral aneurysm in this infant may have been an early manifestation of HHT. Brain CT scan study seems mandatory in every infant born to a mother with HHT.

[Acute hepatic insufficiency disclosing congenital syphilis]. / Insuffisance hépatique aiguë révélant une syphilis congénitale.

A breast-fed boy, born to first-cousin parents, had been vomiting since birth; his general condition remained good until age 6 weeks when vomiting became more frequent, and his status suddenly worsened, with polypnea, shock, hypothermia, jaundice, presence of blood in urine, gastric juice, stool, and bleeding tendency during veno-punctures. There was an huge hepatomegaly and a splenomegaly. Hypoglycaemia, metabolic acidosis, severe blood coagulation disturbances, elevated liver enzymes, hypoalbuminemia, pointed to an acute liver failure. He was resuscitated with current supportive measures, and was given a wide spectrum antibiotherapy. Because serologic tests for syphilis were positive in the child and his mother, including the presence of specific IgM the infant was then given Penicillin G therapy only, which resulted in a complete recovery. One month later, a needle liver biopsy showed residual signs of hepatitis. Other possible infectious or metabolic causes of acute liver failure occurring early in life had been excluded.
