The authors present the study of four children with arteritis as vascular complication of acute bacterial meningitis. They report pathophysiological mechanisms involved in vascular lesions, and progress in the understanding of these complications.
The study of CSF fistulae, and especially those involving otolaryngological anomalies, must be based on the search for the causative problem of recurrent meningitis. Congenital malformations, post-traumatic and post-operative situations or even diseases involving the cranial bones are basic causes that should be studied. Currently, cranial trauma is the most usual cause of CSF fistulae, with the possibility of recurrent bacterial meningitis.
A sample of 4554 of newborn was used to study the distribution of the head circumference measure shortly after birth. The sample is part of the cohort born in Ribeirão Preto, Brazil, from June 1st, 1978 to May 31st, 1979. It was possible to show that such measure follows a normal distribution for both sex (either separately or together) and to calculate 'normality limits' for practical use.
The authors review papers and researches about skull growth in newborns and infants: they analysed and correlated anthropometric data with maternal biological and social factors.
The authors report a case of Pasteurella multocida meningoencephalitis in a 5 week-old female infant, with special attention to clinical, laboratory and evolutive features. A moderate neurological sequel was observed at follow-up examinations. A brief review of the importance of P. multocida in human pathology is presented on the basis of the international literature, since the authors did not find any Brazilian reports. The most important feature on P. multocida is the prevalence of bacterial meningitis at the extremes of age. Otherwise, significant mistaken was found between Gram stained smears of body fluids for P. multocida and Haemophilus influenzae or Neisseria meningitidis. Because its role in infections following animal bite or scratch and its opportunistic feature, P. multocida must be included among the possible etiologic agent of bacteremia or sepsis in patients with liver cirrhosis or immunosuppression.
A case of neonatal apnea is reported. Clinical, laboratory, radiological and pathological findings are discussed. The failure of response to therapeutic procedures is suggestive of different cause than anoxia.
Non-ketotic hyperglycinemia is one of inborn metabolic errors that manifest by epileptic seizures of difficult control from the first days of life in hypotonic newborn children. The lack of enzyme that catalyzes the conversion of glycine to hydroxymethyltetrahydrofolic acid, carbon dioxide and ammonia, in liver and brain, results in increased concentration of glycine in blood. It is reported in this study a case of non-ketotic hyperglycinemia diagnosed in neonatal period and characterized by hypotonia and non-controlled multiple seizures. The clinical and electroencephalographic findings, treatment as well as anatomopathologic study are discussed.

Report of a case of Maple syrup urine disease in a female neonate, with diagnosis at 26th day of life. The neurological picture consisted of alternating periods of hyper with hypotonicity, seizures, lethargy, poor feeding and respiratory arrest. Demonstration of elevation of plasma branched-chain amino-acids, was the most widely available confirmatory test, and the therapy with MSUD resulted in improvement of the patient.
