An 18-year old girl developed acute fulminating meningococcaemia with meningitis, coma, shock, coagulation disorders and extensive purpura. Measurement of intracranial pressure showed severe intracranial hypertension. After medical treatment of shock and intracranial hypertension had failed, external drainage of the cerebrospinal fluid was performed in the lumbar region, using a 16 G silicone catheter. This controlled the intracranial hypertension; also the state of shock regressed and the patient became fully conscious. The lumbar drainage was maintained for 12 days during which 3180 ml of blood-stained cerebrospinal fluid were evacuated. The fluid was sterilized by antibiotics as early as the 1st day of the disease, but it remained positive for bacterial antigen up to the 9th day. Cure was obtained without neurological sequelae, thanks to the lumber drainage which controlled intracranial hypertension and removed large amounts of microbial toxins.

To determine the importance of intracranial hypertension in central nervous system acute infections, we studied intracranial pressure (ICP) in 27 patients, aged 45 days to 13 years. Fourteen had meningitis and 13 had encephalitis; all were in deep coma with a Glasgow Coma Scale 7 or less. Intracranial hypertension defined by a mean ICP above 15 mm Hg was observed in 12 patients with meningitis (86%) and in 9 with encephalitis (69%). Patients with meningitis exhibited a very early and severe intracranial hypertension. A striking difference is noted between survivors and non-survivors who had a very high maximal ICP with a severe reduction in cerebral perfusion pressure. Intracranial hypertension occurred in all patients with acute primitive encephalitis but only in 3/7 patients with post-infectious encephalitis. ICP monitoring seems to be important in the comatose forms of bacterial meningitis in the early period, herpes encephalitis and postinfectious encephalitis with severe status epilepticus.

This paper investigates 21 patients (16 infants and 5 children) with Pneumococcal meningitis, 15 of which presented with a severe form. Intracranial pressure (IP) monitoring was performed in 7 patients who all had severe (4) or mild (3) intracranial hypertension (IH). Twelve children had a favourable outcome, 7 had sequelae (3 severe) and 2 died from coning, one before monitoring, the second after exhibiting the highest IP and the lowest cerebral perfusion pressure of the series. The 3 children with severe sequelae had a severe form (2) or a mild but prolonged form (1) of IH. The 4 patients who recovered with moderate sequelae presented severe (1), mild IH (1) or were not monitored (2). There were 14 cases with neurological complications. In 8 patients, this seemed to be related to cerebral oedema and IH; coning caused the death of 2 of them; the 6 others exhibited lesions of cerebral oedema on CT-scan, isolated or associated with cerebral infarction or subdural effusion. In the 6 others patients, IP monitoring was not performed; there was no evidence of cerebral oedema on CT-scan; 2 exhibited cerebral infarction and 3 a moderate ventricular dilatation; 2 had hemodynamic problems from acute pneumococcemia in one case and neurovegetative disturbances associated with cerebral infarction in the second. Pneumococcus meningitis remains a severe disease. The prognosis of severe forms can be improved by IP monitoring since IH seems to be the most frequent mechanism of complication.

The criteria of the cerebrovascular Moyamoya disease is defined by the characteristic findings of its cerebral angiograms, as follows; 1) The internal carotid siphon is narrowed or obstructed bilaterally. 2) The "Moyamoya vessels" are observed at the base of the brain or the basal ganglionic regions. 3) Main trunks of the cerebral arteries such as the anterior, the middle, and/or the posterior cerebral arteries are often not or poorly visualized. 4) Its etiology is unknown. It has been known that the occlusion of the internal carotid fork with Moyamoya vessels is not infrequently seen in patients with tuberculous meningitis, sickle cell anemia, head trauma, and so on. In the definition of the disease, patients with known etiology and/or unilateral occlusion in the carotid fork must be excluded. However, the cases who cannot fulfil its criteria of the cerebrovascular Moyamoya disease, but have its characteristic Moyamoya vessels and collateral pathways have been reported. We investigated the findings of cerebral computed tomograms in 13 patients who did not fulfil the criteria of the cerebrovascular Moyamoya disease, but revealed the Moyamoya vessels. The subjects are 5 males and 8 females, ranging 15 to 70 years old. The past histories of 9 patients among them revealed hypertension, radiation therapy for pituitary adenoma, head trauma, aplastic anemia, and the Raynaud phenomenon. By angiographic evaluations, occlusions in the unilateral carotid forks were seen in 7 patients, and stenoses in those were in 5 patients. One patient showed only a severe stenosis in the horizontal portion of the middle cerebral artery.(ABSTRACT TRUNCATED AT 250 WORDS)

To determinate the importance of intracranial hypertension in central nervous system (CNS) acute infections, we studied intracranial pressure (ICP) in 27 patients, age 45 days to 13 years. Fourteen had meningitis and 13 had encephalitis; all were in deep coma with Glasgow Coma Scale 7 or less. Intracranial hypertension defined by a mean ICP above 15 mmHg, was observed in 12 patients with meningitis (86%) and in 9 with encephalitis (69%). Patients with meningitis exhibited a sudden and severe intracranial hypertension. A striking difference was noted between survivors and non survivors who had a very high maximal ICP with a severe reduction of cerebral perfusion pressure (CPP). Intracranial hypertension occurred in all patients with acute primary encephalitis but in only 3/7 patients with post-infectious encephalitis. ICP monitoring seems to be important in the comatose forms of: (1) bacterial meningitis in the early period (2) herpes encephalitis (3) post-infectious encephalitis with severe status epilepticus.

We report the neurological, intellectual and visual outcome of 77 children with hydrocephalus of non tumoral origin. Neurological deficits and epilepsy were common, particularly in those with severe intellectual deficit and with acquired brain damages. Intellectual level prognosis was usually good, although lower than in a healthy population: 75% of children had full intellectual quotient (FIQ) higher than 70 but often, there was an heterogeneous pattern of the IQ with greater differences between verbal and performance results because of poor visual-spatial skills. Attention and syntax comprehension of language disabilities were also specifically encountered. Meningitis or toxoplasmosis secondary to hydrocephalus often resulted in a poor intelligence level but other causes did not influence intelligence level or pattern. Visual-spatial deficits, attention disorders and language disabilities did not seem related to the degree of hydrocephalus or the delay before shunting, but were especially encountered when ventricular dilatation persisted in spite of the operation. Functional amblyopias were frequent, certainly related to strabismus. Optic atrophy was rare and linked to direct compression of the optic nerves or to major and repeated episodes of intracranial hypertension.

During antibiotic treatment for E. coli urinary tract infection and meningitis, a male new born developed a Candida albicans urinary tract infection with a mycotic kidney abscess and pelvicalyceal fungus balls diagnosed by US investigations and confirmed by radiology. Three weeks later a perirenal urinoma with arterial hypertension developed. After surgical treatment of the urinoma the arterial pressure returned to normal.

Forty-eight pregnancies were observed in 35 patients with hyperprolactinaemia divided into 3 groups according to their initial radiological appearances: normal sella turcica (Group I, n = 11), microadenoma (Group II, n = 12) or macroadenoma without suprasellar expansion, visual defect or pituitary deficiency (Group III, n = 12). Twenty-seven patients were treated with Bromocriptine (Br) from the outs six by adenomectomy + Br, one by adenomectomy alone complicated by meningitis and by corticotropic and thyrotropic hormone deficiencies, followed by amenorrhea despite normalisation of the hyperprolactinaemia requiring induction of a first pregnancy with Clomid. As regards the pregnancies induced by Br (43/48), Br was withdrawn at an early stage in Group I and in the majority of cases in Groups II and III. In all, 37 pregnancies came to term; after Br therapy we observed 5 spontaneous abortions and 3 premature deliveries; 2 caesarian sections were performed before term (one case of hypertension and one adenomatous expansion); one early termination was performed for a tumoral complication. One congenital abnormality (oesophageal atresis) was detected. These observations support the results of extensive studies showing no effects of Br on the outcome of pregnancy and no detectable teratogenic effects with this drug. Five pituitary complications occurred during pregnancy after withdrawal of Br; 1 case of headaches with expansion of a macroadenoma cured by adenometry after prophylactic caesarian section before term; 1 case of optic chiasma compression (Group III) which responded to emergency surgery and 2 cases of pituitary apoplexy (Groups II and III) which responded favourably to Br and in which pregnancy continued normally.(ABSTRACT TRUNCATED AT 250 WORDS)

Investigation of the bioelectrical activity and cerebral blood content has shown different changes in the baseline EEGs and REGs in children with acute serous meningitis. The visual assessment of the EEGs revealed in 52% of cases paroxysmal activity, diminished regularity of the dominant rhythm, etc. The findings of the cross-correlation analysis indicated impairment of the space-time organization of the potentials: there was a reduction in the functional activity of the anterior associative structures, particularly in the left hemisphere, and lagging of the electrical processes in the frontal zones of the right hemisphere from potentials of other centres. Changes in the cross-correlational functions of biopotentials were attended by alterations in the REG parameters, in particular by a decreased amplitude of the pulse wave, elevated vascular tone and increased interhemispherical asymmetry. The role of intracranial hypertension in the genesis of identified disorders is discussed.
