    Subdural collections caused by Salmonella infection are rarely encountered in children. We present two cases caused by non-typhi Salmonella, one a four-and-a-half-month-old boy presenting with subdural effusion, and the other, a 16-month-old boy with empyema. The diagnosis was confirmed on blood and subdural pus cultures. One patient had status epilepticus following focal fit, and the other had prolonged fever without any localising signs of infection on admission. They responded well to prompt surgical drainage and prolonged systemic antibiotic therapy. Contrary to previous reports, both patients showed favourable outcome in terms of neurological sequelae.

    We report the case of a 25-year-old Malay woman, admitted for preterm delivery at 35 weeks' gestation. Vaginal swab did not isolate any organism. She delivered a baby girl who developed respiratory distress syndrome, requiring ventilation. Although chest radiograph showed hyaline membrane disease with pneumonia, septic workout was negative. The mother was discharged on the next day. Seven days postpartum, the mother presented with fever and fits and was diagnosed to have meningo-encephalitis. Lumbar puncture isolated group B Streptococcus (GBS) and MRI revealed a superior cerebellar abscess. She was treated and survived the episode. This case illustrates the uncommon situation where GBS infection was confirmed via maternal septic workout rather than neonatal, although both presented with severe disease.

    A 2-year-old boy with underlying congenital cyanotic heart disease presented with seizures and fever and was found to have bilateral parietal cerebral abscesses. Drainage of the pus from the abscesses was done in stages; on the day of admission, four days after admission and 3 weeks after admission. Although the pus from the first drainage did not grow any organisms, the pus from the second drainage on the fourth day of admission yielded a mixed growth of Eikenella corrodens and Streptococcus milleri. Following the second drainage of pus, the child was noted to have mild weakness (grade 3/5) and increased tone in the left upper limb. Three weeks after admission, due to recurring fever, further neurological signs and findings of an enlarging right cerebral abscess on a repeat CT scan, a third drainage was carried out. However no growth was obtained from this specimen. This patient was managed both surgically and with appropriate antibiotics. Over the next four months, serial CT scans revealed gradual resolution of the abscesses with disappearance of the surrounding oedema. The child showed gradual recovery of his left sided weakness with resolution of tone and reflexes to normal.

    Micrococcus spp. are commensal organisms colonizing the body surfaces of humans. In a few instances these organisms have been reported to colonize ventricular shunts. We report a patient, with no overt evidence of immunosuppression, in whom Micrococcus luteus was responsible for intracranial suppuration at multiple sites.

    31 cases of intracranial abscess seen over a period of 10 years showed a peak incidence in the second and third decades of life with a male preponderance. Tetralogy of Fallot and other congenital cyanotic heart diseases were the predominant associated factors (32%). The commonest site of infection was the frontal lobe. Gram-stained smears of pus proved to be extremely useful. The majority of the organisms (82%) were either microaerophilic or anaerobic bacteria with Streptococcus milleri being the most frequent isolate. With the exception of Corynebacterium species, all isolates were susceptible to penicillin or chloramphenicol, most being susceptible to both.

    Cladophialophora bantiana is a dematiaceous fungus with a predilection for causing central nervous system (CNS) infection manifesting as brain abscess in both immunocompetent and immunocompromised patients. In this paper, we report comprehensive genomic analyses of C. bantiana isolated from the brain abscess of an immunocompetent man, the first reported case in Malaysia and Southeast Asia. The identity of the fungus was determined using combined morphological analysis and multilocus phylogeny. The draft genome sequence of a neurotrophic fungus, C. bantiana UM 956 was generated using Illumina sequencing technology to dissect its genetic fundamental and basic biology. The assembled 37.1 Mb genome encodes 12,155 putative coding genes, of which, 1.01% are predicted transposable elements. Its genomic features support its saprophytic lifestyle, renowned for its versatility in decomposing hemicellulose and pectin components. The C. bantiana UM 956 was also found to carry some important putative genes that engaged in pathogenicity, iron uptake and homeostasis as well as adaptation to various stresses to enable the organism to survive in hostile microenvironment. This wealth of resource will further catalyse more downstream functional studies to provide better understanding on how this fungus can be a successful and persistent pathogen in human.

    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.

    Burkholderia pseudomallei infection of the central nervous system (CNS) is rare with less than 50 cases reported over the last 30 years. The retrospective melioidosis study at University Malaya Medical Centre has documented three cases of CNS melioidosis out of more than 160 cases of melioidosis since 1978. There were two patients with brain abscess and one with spinal epidural abscess. The predisposing factors were: one patient was an aboriginal farmer and the other two were diabetic. Their age ranged from 17 to 45 years. Prominent neurological features were limb weakness, cranial nerve palsy (6th and 7th) and visual disturbance. CT brain scan and MRI spine showed abscess formation, subdural collection, and spinal epidural collection, osteomyelitis of vertebra and occipital bone and also sagital sinus thrombosis. All these patients underwent surgical drainage leading to bacteriological diagnosis as well as appropriate long-term antibiotic therapy. All had good recovery at 6 months after completion of treatment.
