Calcium and magnesium have been measured in cerebrospinal fluid by atomic absorption spectrophotometry in children. The normal values on 194 C.S.F., obtaining for the calcium x: 5.24 mg. % and s: +/- 0.378 mg. % [50--56 % lower than serum values] and for magnesium x: 2.64 mg. % and s: +/- 0.155 mg. % [19--33 % higher than serum values] are found. Higher values of calcium at birth and on the first year of life and no differences with magnesium are noted. Applying the t-test, between normal values obtained and the different pathological entities, authors find singificant differences on the level of calcium, finding higher values on the following diseases: dehydration by diarrhoea, poliomyelitis, anoxy, tumours, bacterial meningitis. Magnesium showed values significantly higher in dehydration by diarrhoea and epilepsy, and values significantly lower on febrile convulsions and virical and bacterial meningitis.

In most developing countries, bacterial meningitis (BM) is associated with a high case-fatality rate. The search for a simple, convenient, and inexpensive antibiotic treatment remains a priority. In this study, a non-blinded, multicentre, randomised clinical trial of 528 cases of BM was done in two hospitals in Mali and Niger, between March, 1989, and May, 1990, to see whether a double injection of long-acting chloramphenicol (on admission to hospital and 48 h later) is as effective as a course of intravenous ampicillin (8 days, 4 times a day). The cumulative case-fatality rate on day 4 (principal end-point) among the chloramphenicol (254 patients) and ampicillin (274) groups were, respectively, 28% and 24.5% (relative risk 1.14, 95% confidence interval 0.86-1.52). No outbreak occurred during the study period. The hospital case-fatality rate was 33.1%. Main risk factors for death were associated with clinical condition on admission--ie, altered consciousness, convulsions, or dehydration. The case-fatality rates were 13% (21/161) for Neisseria meningitidis, 36.1% (48/133) for Haemophilus influenzae, and 67% (77/115) for Streptococcus pneumoniae. In a multiple logistic regression model, controlling for the differential distribution of potential risk factors (including bacterial species), there was no difference between treatment groups. Our findings suggest that long-acting chloramphenicol is a useful first-line presumptive treatment for BM in high-incidence countries.

Inpatient and community-based care can be complementary in relation to the management of HIV disease. Medical records from 200 inpatients of Chikankata Hospital near Lusaka, Zambia and 200 home based patients were examined and compared for the common symptoms of presentation of HIV disease, associated opportunistic infections, and treatment protocols. Drug costs of both groups were also compared. The most common respiratory symptoms in the 2 groups are cough, chest pains, weight loss, and hemoptysis. Treatment employed for these symptoms were cortimoxazole, penicillin V, erthromycin, and tetracycline. Acetyl saliclic acid and paracetamol were used for pain relief in both groups. Gastointestinal system symptoms for both groups were diarrhea, weight loss, abdominal pain, and vomiting. Cotrimoxazole and metronidazole were used in treating diarrhea. Additional treatment protocol for the 2 patient samples included oral rehydration therapy for dehydration, antacid or bismuth subsalicylate for diarrhea and enteritis, and mycostatin for oral candidiasis. Central nervous system symptomatology included headache, dementia, neckace, and lethargy. Chloramphenicol was employed in treating bacterial meningitis. Diazepam and chlorpromazine were effective for restless patients. Genito-urinary system symptomatology for the 2 groups included dysuria, genital ulcers, hematuria, viral warts, and buboes. Antibodies were used for sexually transmitted diseases and infections. Skin symptomatology included rash and dermatitis, herpes zoster, abscess, kaposi's sarcoma, ulcers, furunculosis, and discharging anal sinus. In treating these symptoms, hospital based care and home based care were similar. Overall, it was found that hospital treatment protocols were detailed, expensive, and time consuming. Furthermore, hospital treatment for HIV positive patients is more expensive than HIV negative patients; hospital costs for 50 HIV negative patients totaled US$415.94 compared to US$1204.98 HIV positive/PTB negative patients and US$1705.62 for HIV positive/PTB positive patients. Drug cost/patient admission is increased by 469% if HIV positive. (author's modified).

Four hundred thirty-four febrile infants two months of age or younger were evaluated in the emergency departments of five major teaching hospitals over a one-year period. A culture-proven bacterial infection was present in 3.5% of the infants; bacteremia was detected in 3.3%. Bacterial meningitis was present in 2.4%, and aseptic meningitis was noted in 13.4%. Twenty-one percent had clinically apparent serious disease including pneumonia, otitis media, and gastroenteritis with dehydration. Six variables (age less than 1 month, lethargy, no contact with an ill individual, breast-feeding, total polymorphonuclear greater than or equal to 10,000/mm3 and band count greater than or equal to 500/mm3) were correlated with bacterial infection by step-wise discriminant analysis. However, these findings were neither sensitive nor specific enough to be clinically useful. Management varied, and 62% of the infants were hospitalized. Fifty-four percent, some of whom were managed as outpatients, received antibiotics. Febrile infants two months of age or younger require a comprehensive emergency department assessment, including appropriate laboratory studies (CBC, differential, urinalysis and culture, lumbar puncture, and blood culture), since 3.5% have bacterial infection that may be life-threatening. Hospitalization is warranted if the infant appears ill, laboratory studies indicate serious infection, or follow-up care is uncertain.

A case of a large empty sella was reported, which was intrasellar herniation of the third ventricle associated with a prolactinoma. The patient was a 46-year-old female admitted due to consciousness disturbance with pyrexia and vomiting. She had amenorrhea, galactorrhea and sterility in her past history. On admission, physical and neurological examinations revealed severe dehydration, systemic edema, systemic hypotension, nuchal rigidity, papilloedema and goiter. A spinal tap was performed and revealed an increase in CSF pressure. Laboratory data indicated CSF lymphocytosis, an increase in CSF protein content, high titers of serum microsome test, a low concentration of anterior pituitary hormones in serum except for PRL, and an unusually high concentration of PRL in serum and CSF (4680 and 222ng/ml, respectively). Plain films of the skull showed destructive enlargement of the sella turcica. The patient was diagnosed as having non-bacterial meningitis, chronic thyroiditis and a prolactinoma with hypopituitarism and was then admitted to our department. Except for amenorrhea she was asymptomatic under the administration of levothyroxine, hydrocortisone and bromocriptine. CT scan, MRI, pneumoencephalography and CT cisternography as further examinations disclosed the intrasellar herniation of cisterns and the third ventricle, which were surrounded by an intrasellar parenchymal layer. This layer was thought to be still viable prolactinoma tissue. We supposed the third ventricle entered the enlarged sellar cavity following the spontaneous degeneration of the large prolactinoma. Although we could find some documented reports of similar cases, the complete herniation of the third ventricle secondary to degeneration of an adenoma might be rare.(ABSTRACT TRUNCATED AT 250 WORDS)

Since the mechanisms underlying hyponatraemia in meningitis are poorly understood, we retrospectively reviewed the records of 187 paediatric patients with bacterial meningitis treated at the Department of Pediatrics, University of Bern, Switzerland, between 1982 and 1994. The degree of dehydration calculated from naked weight on admission and at 5 days was consistently (by 2.8 x 10(-2) and significantly more pronounced in 30 hyponatraemic (plasma sodium 130 mmol l-1 or less) than in 157 normonatraemic patients (plasma sodium 131 mmol l-1 or more). Furthermore, a tendency towards reduced sodium excretion was noted in hyponatraemic patients. The results suggest that in bacterial meningitis hyponatraemia is mostly induced by clinically latent fluid volume depletion.

For almost 20 years, fluid restriction has been applied in the management of bacterial meningitis. This recommendation was based upon the findings of elevated plasma levels of arginine vasopressin in children with bacterial meningitis and their interpretation as evidence for inappropriate secretion of antidiuretic hormone. Recent data indicate that this interpretation was erroneous and that elevated levels of arginine vasopressin is the consequence of hypovolemia in the majority of cases of bacterial meningitis. In addition, fluid restriction appears to worsen the prognosis. As a consequence, not only fluid restriction must not be systematically applied in the management of bacterial meningitis, but appropriate fluid and sodium intakes are necessary to compensate hypovolemia and dehydration. Only a small number of cases with evidence of inappropriate secretion of antidiuretic hormone will require fluid restriction.

Experimental bacterial meningitis due to Streptococcus pneumoniae in infant rats was associated with a time-dependent increase in CSF and cortical urate that was approximately 30-fold elevated at 22 h after infection compared to baseline. This increase was mirrored by a 20-fold rise in cortical xanthine oxidoreductase activity. The relative proportion of the oxidant-producing xanthine oxidase to total activity did not increase, however. Blood plasma levels of urate also increased during infection, but part of this was as a consequence of dehydration, as reflected by elevated ascorbate concentrations in the plasma. Administration of the radical scavenger alpha-phenyl-tert-butyl nitrone, previously shown to be neuroprotective in the present model, did not significantly affect either xanthine dehydrogenase or xanthine oxidase activity, and increased even further cortical accumulation of urate. Treatment with the xanthine oxidoreductase inhibitor allopurinol inhibited CSF urate levels earlier than those in blood plasma, supporting the notion that urate was produced within the brain. However, this treatment did not prevent the loss of ascorbate and reduced glutathione in the cortex and CSF. Together with data from the literature, the results strongly suggest that xanthine oxidase is not a major cause of oxidative stress in bacterial meningitis and that urate formation due to induction of xanthine oxidoreductase in the brain may in fact represent a protective response.

Cerebral sinovenous thrombosis is a rare but potentially serious condition often occurring in children with nonspecific presenting features. Much remains to be learned about the long-term outcome of infants with cerebral sinovenous thrombosis. We report a series of four patients taken from a prospective database of neonates with sinovenous thrombosis who subsequently developed infantile spasms, three with hypsarrythmia on electroencephalography and one with multiple independent spike foci. The first patient presented at 2 weeks of age with hypernatremia, dehydration, and seizures. He was found to have extensive thrombosis and hemorrhagic infarction of the right basal ganglia. The second patient presented at 5 weeks of life and was found to have sagittal sinus thrombosis with bilateral intracranial hemorrhage. The third patient presented with seizures on day 1 of life and was found to have venous thrombosis involving the torcular, extending into the sagittal sinus. The fourth patient presented at 3 weeks with lethargy and seizures. He was diagnosed with bacterial meningitis and also had extensive sinus thrombosis. All patients developed infantile spasms at ages 9, 7, 11, and 10 months, respectively. This is the first report in the English literature describing infantile spasms as a possible outcome of sinovenous thrombosis in early infancy.

Strongyloidiasis, a chronic infection caused by the intestinal parasite Strongyloides stercoralis, is prevalent in the Nansei Islands of Japan. Here, we report our findings on a case of strongyloidiasis complicated with steroid-resistant minimal change nephrotic syndrome in a 69-year-old male resident of Fukuoka Prefecture who had lived in Yakushima, one of the Nansei Islands, until age 15. In October 2006, he developed proteinuria and edema, and was diagnosed with minimal change nephrotic syndrome on the basis of the renal biopsy findings. Following treatment with prednisolone, the level of proteinuria decreased to 0.29 g/day by day 35. However, 5 days later (day 40), the patient developed persistent watery diarrhea and vomiting, leading to dehydration and malnutrition. Pneumonia and bacterial meningitis subsequently developed (day 146); filarial (infectious-type) and rhabditiform (noninfectious-type) S. stercoralis larvae were detected for the first time in the patient's sputum, gastric juice, feces, and urine. Although treatment with ivermectin was started immediately and the parasitosis responded to the treatment, the patient died of sepsis. Consequently, although strongyloidiasis is a rare infection except in endemic regions, it is essential to consider the possibility of this disease and begin treatment early for patients who have lived in endemic areas and who complain of unexplained diarrhea during steroid-induced or other immunosuppression.
