Microbiology of cerebral abscess: a four-year study in Malaysia.

A prospective study was carried out to determine the aetiology of cerebral abscess in relation to the primary source of infections. Seventy-five patients with cerebral abscess were included in the study in the period January 1985 to December 1988. More than half of the patients studied had single lesions and the overall most common sites were in the frontal and parietal regions. Chronic suppurative otitis media, cyanotic congenital heart diseases and meningitis were among the important predisposing conditions in these patients. Approximately 25% of the patients with cerebral abscesses had no documented antecedent infections. Pure cultures were found to be predominant (66.7%) and sterile cultures were obtained from 10 (13.3%) patients. Streptococci were isolated from 23 (30.7%) patients, the commonest species being Streptococcus milleri. Proteus sp, Pseudomonas aeruginosa, Pseudomonas putrifaciens and Bacteroides sp were almost exclusively found in cerebral abscesses secondary to chronic suppurative otitis media; these organisms were found in mixed cultures. Streptococcus milleri, Bacteroides sp and Eikenella corrodens were found in pure cultures in patients with cyanotic congenital heart disease. In patients with ventriculoperitoneal shunts in-situ, Staphylococcus aureus, Staphylococcus epidermidis and diphtheroids were common. Anaerobes were found in 15 (20.0%) patients, the majority in mixed cultures. Culture, as well as gas-liquid chromatographic analysis of volatile fatty acids of cerebral pus, was carried out to enhance the detection of the anaerobes. Based on these findings, an antibiotic regimen consisting of penicillin, chloramphenicol and metronidazole is recommended as an initial therapy while awaiting culture and sensitivity results.

Evaluation of therapies in the treatment of Helicobacter pylori associated non-ulcer dyspepsia.

This randomised double blind placebo controlled study evaluated the effectiveness of colloidal bismuth subcitrate (CBS), ampicillin and their combination in the treatment of Helicobacter Pylori in non-ulcer dyspepsia (NUD) and assessed if elimination of this organism is associated with improvement of gastritis and the symptoms. Forty-eight NUD patients with H. pylori and histologic gastritis were randomly allocated to one of the three regimens for 28 days. Symptoms were assessed before and after treatment. Forty-three patients completed the trial. Repeat endoscopy within 48 hours of completing treatment showed suppression of H. pylori in 6 of 7 patients (85.7%) on combined therapy and one of 8 patients (12.5%) on CBS therapy (p = 0.0205). There was no suppression of the bacteria in patients treated with ampicillin. Repeat endoscopy performed 2 weeks after completing treatment showed suppression of H. pylori in 3 of 7 patients (42.9%) on combined therapy and none in the other two groups. Patients on combined therapy who had suppression of H. pylori, 48 hours or 2 weeks after completing treatment were noted to have historical improvement of their gastritis (p = 0.0001 and p = 0.05 respectively). This was also associated with improvement of symptoms in these patients.

Melioidosis with brain abscess.

Central nervous system involvement in melioidosis is rare. We describe a 48 year old woman who developed septicaemia and a brain abscess due to Pseudomonas pseudomallei. Since there is a continuing practical problem in bacteriological confirmation of the aetiological agent, diagnosis of melioidosis has to be made on clinical suspicion.

Pneumococcal infection in hospitalized patients: a four-year study in Malaysia.

A total of 90 cases of pneumococcal infections were identified at a major referral hospital in Kuala Lumpur, Malaysia during a study period of four years. Pneumonia was the most common clinical presentation (41 cases) followed by meningitis (19 cases). Of 48 patients who were followed-up during the microbiology consultation round, 11 died, 9 were children below two years old. Capsular typing was carried out on 57 strains of Streptococcus pneumoniae isolated from blood and body fluids of 43 children and 14 adults. 38 strains isolated from pharyngeal specimens were also typed. Types 6A (11 strains), 6B (7 strains), 14 (8 strains) and 19A (8 strains) predominated in children. The strains from older patients comprised 3 isolates from cerebrospinal fluid (types 18B, 6B and 14), five from blood (4 strains, type 1 and 1 strain, type 4) and six from pus (1 strain, type 14, 3 strains type 23F and 2 strains type 34). The isolates from pharyngeal specimens belonged to capsular type similar to those implicated in infections. 90% of the types reported in this study are included in the 23 valent pneumococcal vaccines. Minimum inhibitory concentrations of penicillin, cefuroxime, chloramphenicol and rifampicin were determined for selected strains. 4.1% of isolates were resistant to penicillin (3/74), 4.5% to cefuroxime (2/44), 6.5% to chloramphenicol (3/46) and 14.6% to rifampicin (6/41).
