We retrospectively reviewed 159 episodes of bacteraemic pneumococcal infection in 157 adult patients at the Helsinki University Central Hospital during two periods between 1976 and 1979 and 1986 and 1989. We looked especially at changes in underlying diseases and prognostic factors. The overall case fatality rate was 21% and there was a small diminishing trend in that rate from 28% (16/58) in the late 1970s to 17% (17/101) in the late 1980s. The patients who died in the late 1980s were younger than those who died in the earlier period. The most common underlying factors were alcohol abuse, cardiovascular diseases and chronic obstructive pulmonary diseases. Old age was neither a predisposing factor nor did it predict the outcome. No significant changes in underlying diseases or prognostic factors were noted during the two periods studied except a small decrease in connective tissue diseases as underlying conditions. The factors related to increased fatality included hepatic cirrhosis, a combination of pneumonia and meningitis, complications such as shock, respiratory insufficiency, central nervous system disorders and circulatory acidosis, and laboratory findings such as thrombocytopenia, absence of leucocytosis and increased amounts of serum creatinine, aspartate aminotransferase and alanine aminotransferase on admission to the hospital. Previous splenectomy and malignant diseases were not associated with higher mortality. The thrombocytopenia at the time of positive blood culture and the circulatory acidosis as a complication seemed to be independently the most useful predictive factors for a fatal outcome using multivariate logistical regression analysis after adjustment to classic risk factors.

It is shown that the dynamics of lipid peroxidation (LPO) in patients with purulent meningitis is unspecified in character and is encountered both in meningococcal and pneumococcal infection. The level of secondary LPO products and the degree of hyperfermentemia, which are determined according to the dynamics of changes in the activity of aspartate transaminase, are objective characteristics of the severity of the patient's condition and reach maximum on the 5th day of the disease. The correlation between the dynamics of the primary LPO products and the ceruloplasmin/transferin coefficient allows the severity of the disease to be prognosticated.

A total of 740 consecutive children aged between 6 months and 12 years who presented with acute encephalopathic illnesses during a three year period were assessed both clinically and by laboratory investigations. Cerebrospinal fluid was examined for the presence of cells or other abnormal substances, and any organisms were cultured. Blood examination included white cell count and estimations of haemoglobin, urea, glucose, and electrolyte concentrations and serum alanine aminotransferase and aspartate aminotransferase. A firm diagnosis was established in 278 patients (38%). Pyogenic meningitis (n = 134), measles encephalopathy (n = 38), and electrolyte imbalance (n = 23) were important causes in this group, cerebral malaria (n = 4) was uncommon and there were no cases of Reye's syndrome. The diagnoses of the remaining 462 were combined under the heading 'acute unexplained encephalopathy'. Altogether 394 of the 462 patients underwent virological investigations for arboviruses and 92 (23%) had one or more indicators of Japanese encephalitis. No other arboviruses could be isolated. Throat swabs from 187 patients with acute unexplained encephalopathy were studied on monkey kidney tissue cell lines of which 14 were positive (8%). These were identified as adenovirus, parainfluenza, influenza, poliomyelitis, Coxsackie, and echovirus; in two cases the virus was untypable. Japanese encephalitis is an important cause of acute childhood encephalopathy in this region. Clinical features of the illness may be mimicked by several disorders which require specific treatment. Thirty four of the 92 died (37%).

The possible development of hepatotoxic effects as a result of high dosages of isoniazid, rifampin, pyrazinamide, and ethionamide was assessed in 56 young children (median age, 22 months) treated for severe tuberculous meningitis (TBM). Only one of the 56 children became jaundiced, probably as result of hepatitis A infection. Of 33 children observed for at least eight weeks, only five (15%) had normal serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyl transferase levels throughout, but in only three patients were AST or ALT values greater than 200 U/L, and enzyme levels tended to normalize toward the end of the period. In this group of 33 children, those at stage III TBM had higher enzyme levels than did those at stage II. The remaining 23 children were observed for a mean period of only four weeks, and 18 (75%) had at least one abnormal liver function test result.

We evaluated the effectiveness of 5-day antibacterial therapy for bacterial meningitis in children. The study group included 26 children from 2 months to 15 years of age, admitted with microbiologically confirmed bacterial meningitis in 1990-1993 and treated for 5 days. A historical comparison group of 49 patients treated for 8 to 15 days was used. Penicillin monotherapy (300 mg/kg body weight) was used for meningococcal and pneumococcal meningitis and ampicillin (300 mg/kg body weight) for Haemophilus influenzae b meningitis. On day 5 of therapy the activity of aspartate aminotransferase (AST), lactic dehydrogenase (LDH), creatine phosphokinase (CPK) and gamma-glutamyl-transpeptidase (gamma GT) in the CSF was determined by photocolorimetric assay and the concentration of creatine kinase BB (CK-BB) by ELISA. IL-6 was analysed using EIA technique and a cerebral ultrasound was performed at the time of the termination of the antibacterial therapy. The mean follow-up time was 1.3 years for children in the study group and 3.2 in the control group. The time of hospitalisation was shorter in children treated for 5 days (p < 0.005). Complete clinical recovery was 81% in the study group and 66% in the comparison group at the time of the termination of antibacterial therapy. No relapses occurred. The activity of AST, CPK, LDH, and gamma GT in the CSF had returned to normal by the 5th day of therapy, but almost a 7-fold higher concentration of CK-BB was registered. The concentration of IL-6 in the CSF decreased with the therapy from 1,800 pg/ml to 685 pg/ml but still remained high.(ABSTRACT TRUNCATED AT 250 WORDS)

A 14-day-old neonate was transferred to our university hospital because of respiratory distress and mild disturbance of consciousness. He had no history of abnormal pregnancy or delivery, but had developed apnea at 6 days old. Thereafter, respiratory distress progressed and his condition deteriorated. On admission to our hospital, several vesicles were found on the left upper arm, and moderate hepatomegaly was also present. Herpes simplex virus (HSV) type II genome was detected from serum, spinal fluid, and bone marrow. Laboratory examinations revealed typical abnormalities of disseminated intravascular coagulation, increased levels of serum ferritin, aspartate aminotransferase, and lactate dehydrogenase. Bone marrow aspiration demonstrated activated macrophages and hemophagocytosis. Spinal tap revealed numerous mononuclear cells. Meningitis and virus-associated hemophagocytic syndrome (VAHS) due to systemic HSV type II infection were thus diagnosed. Acyclovir (60 mg/kg/day) and vidarabine were promptly administered. Dexamethasone palmitate and intravenous cyclosporine were also administered for systemic inflammation due to VAHS. Finally, these aggressive therapies rescued the patient without any sequelae. In general, neonatal systemic HSV infection is life-threatening and results in poor intact survival. Our case report suggests that not only antiviral treatment for HSV, but also anti-inflammatory treatment including steroid and cyclosporine should be considered from the early phase of neonatal systemic HSV infection.

Eosinophilic meningitis is a disease characterized by increased eosinophils in the cerebrospinal fluid (CSF), which is the most commonly caused by invasion of the central nervous system by helminths, as occurs in Angiostrongylus cantonensis infections. The rodent Rattus norvegicus is the definitive natural host and humans act as accidental hosts and can become infected by eating raw or undercooked snails or food contaminated with infective L3 larvae. Recently in Brazil there have been four cases of eosinophilic meningitis due to ingestion of infected Achatina fulica. To evaluate biochemical and histopathological changes caused by this parasite, R. norvegicus were experimentally infected with 100 L3 larvae of A. cantonensis. After the anesthetic procedure, serum from the rodents was collected from the inferior vena cava for evaluation of the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALKP), gamma-glutamyl transferase (GGT), total protein and its fractions. During the necropsy, the liver was collected and weighed. Then a 1-g fragment was extracted from the major lobe to quantify the hepatic glycogen and fragment remainder was taken from the same lobe and fixed in Milloning's formalin for histopathological examination. Additionally, helminths were collected from the brain and lungs of the rodents. The activities of AST, ALT, ALKP and GGT in the serum and hepatic glycogen increased in response to infection, while the levels of globulin and total protein increased only in the eighth week of infection and there was a reduction in the levels of serum glucose. Albumin and bilirubin concentrations remained stable during the experiment. Infection with A. cantonensis caused metabolic and histopathological changes in the rodents. This study can contribute to a better understanding of the relationship between A. cantonensis and R. norvegicus.
