From 1996 to 2001, nineteen episodes of bacteremia due to group B Streptococci (GBS) were diagnosed in Siriraj Hospital, Mahidol University. The incidence of early onset group B streptococcal disease (EOD) was 0.27 cases/1,000 live births in 1996, and decreased to 0.10 cases/1,000 live births in 2001. The incidence of the late onset disease (LOD) was 0.05 cases/1,000 in 1996, and there has been none since 1998. All of the infants were inborn. Low birth weight was found in 53 per cent of the infants. Fifty-eight per cent of infants were male. Forty-seven per cent of the infants were born prematurely. None of the mothers had antenatal GBS screening. Only one mother received one dose of intrapartum antibiotic prophylaxis. No risk factor could be identified in 72 per cent of the mothers. EOD accounted for 79 per cent of all infants with GBS infections, with a mortality rate of 40 per cent. All of them died within the first 72 hours of life. Most EOD infants developed disease manifestations within 12 hours of life. Most common clinical manifestations were respiratory distress (74%), temperature instability (68%), cyanosis (63%), hypotension (42%) and lethargy (42%). Only one infant with EOD had meningitis. There were two infants in the LOD group; one of whom had cellulitis, and the other had meningitis. Neutropenia was noted in 42 per cent of all infants. Radiographic studies suggested a diffuse reticulogranular pattern or ground glass appearance in 38 per cent. The chest X-ray was interpreted as normal in 25 per cent of the infants. In conclusion, the incidence of GBS infection in newborn infants in Thailand is still very low but with a very high mortality. Prematurity accounts for almost half of the cases. Even though antepartum screening with intrapartum antibiotic chemoprophylaxis has been recommended in developed counties, its benefit and cost needs to be further investigated in Thailand.

Candida: spp. are becoming one of the most common pathogens associated with sepsis in the setting of neonatal intensive care. Invasive therapies aimed at improving patient survival, particularly among premature infants, contribute significantly to this alteration in the distribution of neonatal pathogens. Prematurity is one of the principle risk factors associated with the development of neonatal meningitis in this patient population. Untreated, neonatal candidal meningitis is associated with a poor outcome both in terms of morbidity and mortality. However, early diagnosis with timely initiation of antifungal therapy will improve outcome significantly. The following review outlines the pathogenesis, clinical features, diagnosis, and current treatment options for neonatal candidal meningitis.

Nosocomial meningitis is uncommon in children. We reviewed the medical records of all children who developed bacterial meningitis at least 72 hours after admission to Mackay Memorial Hospital for the period July 1992 through June 2000. Clinical manifestations, predisposing factors, pathogens, and outcomes were analyzed. Twenty-two cases of nosocomial meningitis were identified, comprising 9.2% (22/239) of all pediatric cases of bacterial meningitis during the study period. The male-to-female ratio was 14:8. All patients were younger than 6 months of age except for one, who was 7 years old. The mean duration between admission and onset of meningitis was 15.3 days (range, 3 to 58 days). Twenty-two organisms were isolated, including 13 Gram-negative bacteria (59%) and 9 Gram-positive bacteria (41%). The most common pathogen was Escherichia coli (5 cases), followed by Enterobacter cloacae (3), Staphylococcus aureus (3), and Chryseobacterium meningosepticum (3). Seventeen patients (77%) had concomitant bacteremia. Predisposing factors for acquisition of nosocomial meningitis included previous treatment with broad-spectrum antibiotics (68%), prematurity with very low birth weight (41%), and total parenteral nutrition (32%). Two patients (9%) had previous neurosurgical intervention. Four patients (18%) died, 3 of whom were low birth weight premature infants. Nine patients (41%) had sequelae, including developmental delay, hydrocephalus, hearing impairment, and epilepsy. Neurosurgery was not a significant risk factor for the development of nosocomial meningitis, while very low birth weight played an important role. Previous intraventricular hemorrhage or hydrocephalus, prematurity with very low birth weight, infection with Gram-negative bacteria, and prior broad-spectrum antibiotic administration were associated with poor outcome.

The aim of this study is to describe the risk factors for bacterial meningitis in newborns, and to analyze the prevalence of these factors, considering or not the low birth weight presence. Fifty newborns with bacterial meningitis were analyzed, excluding the ones with meningomyelocele or congenital infection. In the statistical analysis, the Fisher's exact test was used, considering significant the p < 0.05 values. This study has shown that prematurity, low birth weight and presence of previous infectious diseases in the newborn or in the mother were important risk factors for meningitis. Among low birth weight newborns, invasive procedures, especially tracheal intubation, use of central venous catheter and previous use of antibiotics, were significantly associated to the meningitis occurrence. These results indicate that the improvement in the prenatal care and in the hospital infection control are measures of high importance in the decrease of the incidence of neonatal bacterial meningitis.

An audit of neonatal care at Modilon Hospital, Madang was performed using obstetric and neonatal data for the five years 1995-1999. The overall perinatal mortality rate (PNMR) was 51.1 per 1000 total births with an early neonatal mortality rate (ENNMR) of 12.7 and a stillbirth rate (SBR) of 38.5. 839 neonates aged 0-28 days were admitted to the Special Care Nursery. The male to female ratio was 1.3:1. 186 babies (22%) died. The case fatality rate was higher in males than females (p<0.001). Babies born at health centres or born before arrival had a significantly higher fatality rate than hospital-born babies (p<0.001). The case fatality rate was highest in babies born preterm and declined with increasing birthweight from less than 1000 to 3999 g. The major recorded causes of admission were neonatal sepsis, prematurity, neonatal jaundice, birth asphyxia, respiratory distress and meconium aspiration syndrome. 60% of deaths occurred within 48 hours of admission, 32% between 48 hours and 7 days and 8% at 7 days or older. The proportion of deaths occurring during the afternoon and night shifts was significantly higher than that during the morning shift (p<0.001). This was most likely to be related to staffing levels. The major causes of death were prematurity or low birthweight (27%), sepsis (23%) and birth asphyxia (17%). Other causes of death included congenital abnormalities, meconium aspiration and meningitis. Antenatal care is still not universally available for Papua New Guinean women. Home delivery of high-risk mothers is commonplace, and women delivering in hospital often present in established labour. Perinatal and neonatal problems are therefore frequent. Newborn babies have the right to the best available care. This can only be provided if hospitals and health facilities understand the basic requirements of neonatal care and provide designated space, adequate staffing and proper equipment.

Enterococcal meningitis is a rare complication of neurosurgical procedure or high technology treatment of children and occurs mainly imunocompromised neonates with very low birth weight, severe prematurity and complicates sometime ventriculoperitoneal shunt insertion or perinatal trauma. E. faecalis caused 10 nosocomial meningitis and all strains were susceptible to vancomycin and chloramphenicol, and in our database 90% also to gentamicin and ampicillin. Mortality in our group of 10 children was 20% what is insignificantly higher than overall mortality in the whole cohort of meningitis within last 15 years in our database (15.1%). Early empiric therapy should include also ampicillin or vancomycin, if enterococcal etiology is suspected.

Attention-deficit/hyperactivity disorder is a neurobiological syndrome with an estimated prevalence among children and adolescents of 5%. It is a highly heritable disorder, but acquired factors in etiology are sometimes uncovered that may be amenable to preventive measures or specific therapy. Early reports have described symptoms similar to attention-deficit/hyperactivity disorder that followed brain trauma or viral encephalitis, and recent MRI studies have demonstrated brain volumetric changes that may be involved in the pathophysiology of the syndrome. The American Psychiatric Association's Diagnostic Statistical Manual, introduced in 1968, emphasizes symptomatic criteria in diagnosis. Here, an overview of environmental factors in the etiology of attention-deficit/hyperactivity disorder is presented to encourage more emphasis and research on organic causal factors, preventive intervention, and specific therapies. An organic theory and the genetic and biochemical basis of attention-deficit/hyperactivity disorder are briefly reviewed, and an etiologic classification is suggested. Environmental factors are prenatal, perinatal, and postnatal in origin. Pregnancy- and birth-related risk factors include maternal smoking and alcohol ingestion, prematurity, hypoxic-ischemic encephalopathy, and thyroid deficiency. Childhood illnesses associated with attention-deficit/hyperactivity disorder include virus infections, meningitis, encephalitis, head injury, epilepsy, toxins, and drugs. More controversial factors discussed are diet-related sensitivities and iron deficiency. Early prenatal recognition, prevention, and treatment of environmental etiologies of attention-deficit/hyperactivity disorder may reduce physician reliance on symptomatic modification with medication, a frequent reason for parental concern.

Neonatal hypoxic-ischemic encephalopathy, prematurity, sepsis-meningitis, and serious forms of complex congenital heart disease requiring infant heart surgery are just a few examples of disorders that share high mortality and morbidity rates. Newborn heart surgery represents a period of planned and deliberate ischemia-reperfusion injury, which is obliged to occur to cure or palliate complex forms of congenital heart disease. Advances in cardiothoracic surgical and anesthetic techniques, including cardiopulmonary bypass and deep hypothermic circulatory arrest, have substantially decreased mortality, expanding the horizon to address functional neurologic and cardiac outcomes in long-term survivors. Interest in the functional status of survivors now stretches beyond the newborn period to childhood, adolescence, and adulthood.

There is strong evidence from clinical and experimental animal studies that ureaplasmas can invade the amnionic sac and induce an inflammatory response resulting in chorioamnionitis, preterm labor and neonatal lung injury. The ability of Ureaplasma spp. and Mycoplasma hominis to cause pneumonia, bacteremia, and meningitis in newborns can no longer be questioned. The association of Ureaplasma spp. with bronchopulmonary dysplasia has been supported by the majority of observational studies, but proof of causality is still lacking. The availability of molecular diagnostic technologies has enabled the designation of the two Ureaplasma biovars as individual species, but additional work must be done to establish whether there is differential pathogenicity between the Ureaplasma spp. or among their respective serovars. Future investigations to prevent prematurity should be directed toward identification and localization of specific micro-organisms combined with targeted antibiotic trials to determine whether such interventions can improve long-term infant outcomes.

The aim of this study was to describe and analyse hospital mortality patterns after the Liberian war. Data were collected retrospectively from January to July 2005 in a referral hospital in Monrovia, Liberia. The overall fatality rate was 17.2% (438/2543) of medical admissions. One-third of deaths occurred in the first 24h. The adult fatality rate was 23.3% (241/1034). Non-infectious diseases accounted for 56% of the adult deaths. The main causes of death were meningitis (16%), stroke (14%) and heart failure (10%). Associated fatality rates were 48%, 54% and 31% respectively. The paediatric fatality rate was 13.1% (197/1509). Infectious diseases caused 66% of paediatric deaths. In infants <1 month old, the fatality rate was 18% and main causes of death were neonatal sepsis (47%), respiratory distress (24%) and prematurity (18%). The main causes of death in infants > or =1 month old were respiratory infections (27%), malaria (23%) and severe malnutrition (16%). Associated fatality rates were 12%, 10% and 19%. Fatality rates were similar to those found in other sub-Saharan countries without a previous conflict. Early deaths could decrease through recognition and early referral of severe cases from health centres to the hospital and through assessment and priority treatment of these patients at arrival.
