Imipenem/cilastatin sodium (MK-0787/MK-0791) was evaluated for its safety, efficacy and pharmacokinetics in children. Thirty cases of bacterial infections were treated with MK-0787/MK-0791 at a daily dose of 40 to 222 mg/kg for 2.25 to 13 days. Clinical cure rate was 93% and bacteriological efficacy rate was 88%. Treated diseases included severe tonsillitis due to mixed anaerobic infections, pneumonia, sepsis, brain abscess and soft tissue infections. Two cases, one with periosteomyelitis due to methicillin-resistant S. aureus and the other with pulmonary abscess due to Haemophilus influenzae (other than type b), failed to respond to the MK-0787/MK-0791 therapy. The serum half-life of MK-0787 was 0.892 hour in children with normal renal functions. An episode of convulsions in a case of sepsis with bacterial croup and brain edema was considered to be associated with the MK-0787/MK-0791 therapy. From the present study, MK-0787/MK-0791 appears a safe and effective antibiotic when used in children with a variety of bacterial infections.

An analysis of adverse reactions occurring after receipt of Haemophilus influenzae type b vaccine and reported to the Food and Drug Administration during the first year of marketing of the product was performed. During the period April 1985 to May 1986, adverse reaction reports on 152 patients, excluding those of vaccine failure and concurrent infection, were received. Several adverse reactions not previously recognized, including convulsions, allergic reactions such as anaphylactoid-like and serum sickness-like reactions, and vomiting were received. The vast majority of adverse reactions were benign. Because there are many biases that result in the reporting of or failure to report an adverse reaction, it is not possible to derive a rate of reactions from these data. Furthermore, causality cannot be inferred from any single report. The data, however, indicate that, in light of widespread use of the vaccine, its use appears to be safe.

Acute bacterial meningitis still represents a therapeutic problem. Successful management depends on early administration of large doses of bactericidal antibiotics and adequate treatment of complications, i.e. shock, acute cerebral edema, consumption coagulopathy, convulsions and electrolyte disturbances. Meningitis caused by Neisseria meningitidis or Streptococcus pneumoniae should be treated with benzylpenicillin. If benzylpenicillin cannot be given, chloramphenicol has remained the best substitute. However, cefuroxime or ceftriaxone now seems to offer an alternative to chloramphenicol. The prevalence of beta-lactamase-producing Haemophilus influenzae strains is increasing and chloramphenicol has replaced ampicillin in the treatment of H. influenzae meningitis. Recent studies indicate that cefuroxime, ceftriaxone or moxalactam may be as effective as chloramphenicol in this type of meningitis. In neonatal meningitis, cefotaxime or moxalactam may constitute alternatives to the present regimens with ampicillin-gentamicin, gentamicin-chloramphenicol, cotrimoxazole or gentamicin. Promising results have also been obtained with cefotaxime or moxalactam in elderly patients with meningitis due to Gram-negative enteric bacilli. However, more extensive studies are needed to determine the role of the newer cephalosporins in the treatment of acute bacterial meningitis.

The clinical and laboratory date on 115 pediatric patients with bacterial meningitis are presented. Sixty-one were less than 12 mo of age including 13 less than 1 mo of age. Thirty-nine children were treated prior to admission with antimicrobial agents which obscured accurate bacteriologic diagnosis in eight of them. Gram-negative enteric bacteria, mainly Escherichia coli, were recorded in 9 of 13 neonates. Hemophilus influenzae type B accounted for 56 (52%) of all isolated recorded in those greater than 2 mo of age, of which 35% were resistant to chloramphenicol. Seventy-eight patients (73%) recovered completely following 10 to 14 days of antimicrobial therapy. Fifteen patients died, most of whom were less than 1 yr of age, including five neonates. Major neurologic sequelae included subdural effusions, cerebral abscesses and recurrent convulsions. This study, which documents the infrequency of Streptococcus group B and H. influenzae as etiological agents of neonatal meningitis, indicates that treatment of this disease with ampicillin and an aminoglycoside is efficacious. Chloramphenicol may be the drug of choice in the postnatal period, since H. influenzae is partly resistant to ampicillin.

Cerebrospinal fluid (CSF) was analysed to determine a lumbar puncture (LP) yield for meningitis in 95 children who presented with their first febrile convulsions between July 1993 and June 1994. There were 52 males and 43 females aged six months to six years with a mean age of 21.9 +/- 13.0 months at presentation. 87(91.6%) had simple febrile convulsions (SFC) while the remaining 8(8.4%) had complex febrile convulsions (CFC). The majority of the subjects presented with a sudden onset of convulsions that were preceded by a day or two history of fever, coryza, cough and respiratory distress while others had their convulsions preceded by fever and passage of bloody stools. The LP yield for meningitis in this series was 6.3%. The CSF analysis revealed six cases of meningitis comprising an eight month old infant with Haemophilus influenzae type B (HIB) meningitis, two partially treated pyogenic meningitis and three aseptic meningitis. All of them had presented with febrile convulsions without signs of meningeal irritation. Excluding aseptic meningitis from this series, a 3.1% LP yield for pyogenic meningitis is significant enough to recommend continued performance of LP in children with first febrile convulsions, especially if under the age of eighteen months.

To assess septic meningitis in pediatric units in terms of the bacteriologic distribution, mortality, and groups at risk, we conducted a retrospective study in the pediatric department of the Kigali Hospital Center (Rwanda). Based on bacteriologic study of 1215 cerebrospinal fluid samples, there were 321 cases of septic meningitis due to identifiable germs and 68 involving cloudy fluid with no detectable germs, i.e. 1.5% of admissions to the Pediatric Unit of the Kigali Hospital Center. The most common organisms were pneumococcus (36.5%), Haemophilus influenzae (31%), salmonella (13%), and meningococcus (11.5%). Most of the children (75%) presenting septic meningitis were under the age of 5 years. Overall mortality was 38% with rates of 52% and 39% for cases involving pneumococcus and salmonella respectively. The predominant clinical symptoms of pneumococcus meningitis were coma (p:0.000055) and respiratory compromise (p:0.02). In contrast Haemophilus influenzae meningitis was associated with a lower incidence of coma (p:0.05) and malnutrition (p:0.017). Salmonella meningitis was characterized by a higher incidence of fever over 38.9 degrees C (p:0.025) and malnutrition (p:0.01). In patients with meningococcus meningitis, the incidence of convulsions appeared to be higher, at the threshold of statistical significance (p:0.052), whereas coma (p:0062) and respiratory distress (p:0.0024) were uncommon. Independently of etiology, no clinical symptom was associated with a statistically higher risk for death.

During the period January 1980 to December 1990 (11 years) a retrospective study of patients with bacterial meningitis who were admitted to Bangkok Children's Hospital was carried out. There were 618 patients with 77 cases (12.5%) occurring below the age of one month (neonatal meningitis), and 541 cases (87.5%) between one month to 15 years (childhood meningitis). Pseudomonas aeruginosa was the most common pathogenic organism (16.9%) in neonatal meningitis; other causative agents in this age group included Klebsiella pneumoniae (13.0%), group B Streptococcus (11.7%), Escherichia coli and Enterobacter sp (10.4% each). In childhood meningitis, Haemophilus influenzae was the most common causative organism (42.3%), and followed by Streptococcus pneumoniae (22.2%) and Salmonella sp (12.4%). Excluding a 13 year-old leukemic patient, Salmonella meningitis occurred exclusively in infants, 87% of them were under six months, and 13% of them developed relapsing meningitis. Presenting symptoms and signs on admission of neonatal meningitis such as fever (81.8%), convulsions (45.4%), neck stiffness (22.5%), bulging fontanelle (33.3%) and Brudzinski sign (11.5%) were significantly less frequent than in the patients beyond the neonatal period (p < 0.05). The overall fatalities during 1980-1990 were 45.4% and 17.3% for neonatal meningitis and childhood meningitis, respectively. The fatalities of the two age groups declined significantly during 1987-1990 to 26.3% and 11.4% respectively.

This paper on bacterial meningitis looks at aspects inherent in the aetiology and mechanisms underlying neurological damage and pharmacological treatment. Streptococcus pneumoniae, Haemophilus influenzae type b and Neisseria meningitidis are the pathogens most commonly responsible and are able to colonise the host's respiratory mucosae, invade the vascular space, cross the haematoliquoral barrier and survive in the cerebrospinal fluid. The presence of germs in the subarachnoid spaces leads to the onset of inflammation and neurological damage. The most often used pharmacological treatments include, apart from antibiotics, anti-inflammatory drugs (although we have clinical data for corticosteroids only), pentoxyphillin and monoclonal antibodies. Initially empiric, antibiotic therapy is based on the use of drugs that act against the probable pathogenic agents, are capable of surmounting the haematoliquoral barrier and are well tolerated. Prior to the Eighties, the antibiotic of choice was ampicillin associated or otherwise with aminoglycosides. Subsequently, the availability of new drugs (cefotaxime and ceftriaxone) and the appearance of resistance led to changes in therapeutic protocols. Of the carbapenemics, wide spectrum antibiotics with high resistance to beta lactamase, imipenem /cilastatin proved effective although there was a high risk of inducing convulsions in patients with previous neurological damage or kidney failure. Meropenem was able to surmount the haematoliquoral barrier in sufficient concentrations and was well tolerated in patients with prior neurological changes. It has proved effective in clinical studies carried out up to the present.

Children aged 1-59 months admitted to Goroka Base Hospital with signs suggestive of meningitis were recruited to determine what proportion of such children have clinical or bacterial meningitis and to investigate the bacterial aetiology. A laboratory classification of definite, probable, possible, indeterminate and no meningitis was established. Thirty per cent of 697 children had a final clinical diagnosis of meningitis, 12% had culture-proven bacterial meningitis (case fatality rate 34%) and 10% had probable or possible meningitis. Inability to feed, vomiting, drowsiness, "staring eyes" and haemoglobin < 9 g/dl in addition to the classical signs of meningitis were associated with increased mortality. Isolates from cerebrospinal fluid were 62 pneumococci, 22 Haemophilus influenzae type b (Hib) and one Neisseria meningitidis. Including blood culture-proven and antigen-proven Hib disease, Hib and pneumococci accounted for 44% and 46% of bacterial meningitis, respectively, and 23% of pneumococci were intermediately resistant to penicillin. Inability to feed, bulging fontanelle, convulsions in young children, neck stiffness, fever and "staring eyes" were all independently associated with bacterial meningitis. Conjugate Hib vaccine must be given to infants as early as possible. Conjugate pneumococcal vaccines, maternal immunization with 23-valent vaccine and pneumococcal protein vaccines are under investigation for prevention of pneumococcal disease.

Left hemiconvulsions occurred in a 13-month-old girl with Hemophilus influenzae (H. influenzae) central nervous system (CNS) infection. Tc-99m HMPAO brain SPECT showed a focal hyperperfusion area in the right frontal lobe. The patient recovered without complications, and follow-up SPECT revealed markedly improved findings. Tc-99m HMPAO brain SPECT is useful for evaluating focal convulsions associated with H. influenzae CNS infection.
