Abstract
OBJECTIVE To examine the association between time spent in different public day care settings and prescription of systemic antibiotics. Design. Population-based cohort study of 5035 Danish children born in 1997 followed from birth to June 30, 1999. METHODS The study was performed by the linkage of records drawn from administrative registries. Exposure was the total time spent in a day care home or day care center. Outcome was the first prescription of a systemic antibiotic. Possible perinatal and sociodemographic confounding factors were considered by statistical analysis. RESULTS During the first year of life, 39.8% of the girls and 51.1% of the boys received at least 1 antibiotic prescription drug. Enrollment in a day care setting doubled a child's risk of receiving a prescription drug (adjusted relative risk in day care home 1.9, 95% confidence interval: 1.7-2.0; adjusted relative risk in day care center 2.0, 95% confidence interval: 1.7-2.3). Only age confounded the analyses. Age >1 year at the starting time in day care reduced the risk of receiving antibiotic prescriptions during the first 3 months after enrollment. CONCLUSIONS Enrollment in public day care facilities raised the risk of receiving an antibiotic prescription drug to the same extent in day care homes as well as in day care centers, so we cannot recommend one facility over the other based on the present study. Children <1 year old at enrollment were most at risk, suggesting that extension of parental leave may reduce the use of antibiotics.

Abstract
The bacteria most commonly responsible for early-onset (materno-fetal) infections in neonates are group B streptococci, enterococci, Enterobacteriaceae and Listeria monocytogenes. Coagulase-negative staphylococci, particularly Staphylococcus epidermidis, are the main pathogens in late-onset (nosocomial) infections, especially in high-risk patients such as those with very low birthweight, umbilical or central venous catheters or undergoing prolonged ventilation. The primary objective of the paediatrician is to identity all potential cases of bacterial disease quickly and begin antibacterial treatment immediately after the appropriate cultures have been obtained. Combination therapy is recommended for initial empirical treatment in the neonate. In early-onset infections, an effective first-line empirical therapy is ampicillin plus an aminoglycoside (duration of treatment 10 days). An alternative is ampicillin plus a third-generation cephalosporin such as cefotaxime, a combination particularly useful in neonatal meningitis (mean duration of treatment 14 to 21 days), in patients at risk of nephrotoxicity and/or when therapeutic monitoring of aminoglycosides is not possible. Another potential substitute for the aminoglycoside is aztreonam. Triple combination therapy (such as amoxicillin plus cefotaxime and an aminoglycoside) could also be used for the first 2 to 3 days of life, followed by dual therapy after the microbiological results. In late-onset infections the combination oxacillin plus an aminoglycoside is widely recommended. However, vancomycin plus ceftazidime (+/- an aminoglycoside for the first 2 to 3 days) may be a better choice. Teicoplanin may be a substitute for vancomycin. However, the initial approach should always be modified by knowledge of the local bacterial epidemiology. After the microbiological results, treatment should be switched to narrower spectrum agents if a specific organism has been identified, and should be discontinued if cultures are negative and the neonate is in good clinical condition. Penicillins and third-generation cephalosporins are generally well tolerated in neonates. There is controversy regarding whether therapeutic drug monitoring of aminoglycosides will decrease toxicity (particularly renal damage) in neonates, and on the efficacy and safety of a single daily dose versus multiple daily doses of these drugs. Toxic effects caused by vancomycin are uncommon, but debate still exists over the need for therapeutic drug monitoring of this agent. When antibacterials are used in neonates, accurate determination of dosage is required, particularly for compounds with a low therapeutic index and in patients with renal failure. Very low birthweight infants are also particularly prone to antibacterial-induced toxicity.

Abstract
Antimicrobial agents and immunotherapies in the management of neonatal sepsis are discussed. The rationale for the selection of the most commonly used antibacterial drugs, their mechanisms of actions, and indications for use are described. Immunotherapies, both those in clinical use and those under investigation, are discussed. Antibacterial drugs remain the standard of care, but immunotherapy offers the potential for improving outcomes for neonates, especially those who are premature.

Abstract
OBJECTIVE To analyze with regard to age, gender, and diagnosis, the profile, frequency of prescribing, and cost of antimicrobial drugs (AMDs) in hospitalized children. DESIGN Retrospective study of medical records of children hospitalized during 1987 and 1988. SETTING First Pediatric Clinic, Children's Teaching Hospital, Bratislava, Czechoslovakia (now Slovakia). PATIENTS One thousand randomly selected hospitalized children. MAIN OUTCOME MEASURES Patterns of AMD prescribing. Consumption is expressed by the number of drugs and cost per child. RESULTS AMDs were prescribed to 69.9 percent of the patients (average 1.91 per patient). Ampicillin was the drug most frequently prescribed (20.0 percent), followed by oxacillin (12.8 percent). The mean length of stay was 15.9 days. An average of 3.61 drugs from other pharmacotherapeutic categories were prescribed per patient. Most children who received AMD treatment were in the 1-year group (patients between six months and 1.5 years of age [88.6 percent]). CONCLUSIONS This study provides an overview of the prescribing of AMDs and other drugs in hospitalized children in Bratislava.

Abstract
Cefotaxime is a third generation cephalosporin antimicrobial agent which has received wide acceptance as a first-line antibiotic for many infections in neonates, infants and children. With an average elimination half-life of about 1 h, cefotaxime is not considered to be a 'long half-life cephalosporin' like ceftriaxone. For this reason, currently accepted dosage regimens for cefotaxime in infants and children employ a dosage of 50 mg/kg every 6 h. Re-examination of the paediatric pharmacokinetic data for cefotaxime and use of simple multiple-dose pharmacokinetic simulation of alternative dosage regimens was performed. From this analysis, regimens administering 75 mg/kg of the drug every 8 h or every 12 h were projected to produce serum cefotaxime concentrations adequate to effectively kill many of the common pathogens against which the drug is currently indicated for use in children. The clinical utility of these alternative dosage regimens was supported by a review of the medical literature and examination of the clinical results from studies in neonates, infants and children where cefotaxime was administered in 2 to 3 divided doses daily. It would appear, therefore, that increasing the cefotaxime dosage to 75 mg/kg administered at 8 h intervals would result in less frequent drug administration which would not be expected to compromise safety and efficacy. Alternative dosage regimens for cefotaxime merit further consideration and clinical evaluation before they become commonly used in paediatric therapeutics.

Abstract
Ceftibuten (CFB), a new broad-spectrum cephalosporin for oral administration, possesses potent activity in vitro against a wide range of gram-negative and certain gram-positive pathogens frequently encountered in pediatric patients. Its antimicrobial spectrum and dosage formulation suggest a use for CFB in the treatment of otitis media and upper and lower respiratory and urinary tract infections in infants and children. To assess the pharmacokinetic characteristics of CFB in pediatric patients, we completed a multicenter investigation of 49 children (26 females) between the ages of 6 months and 17 years who had normal hepatic and renal functions and no evidence of chronic disease. Pharmacokinetic parameters were determined from repeated blood samples (n = 12) and, when possible, quantitative urine collections (n = 7) obtained over a 12- to 24-h period following a single oral CFB dose of either 4.5 or 9.0 mg/kg of body weight. CFB was quantitated from plasma and urine samples by using a sensitive, microanalytical high-pressure liquid chromatography method. The drug was rapidly absorbed (mean time to maximum concentration in serum = 140 min) and produced apparent peak concentrations in plasma (Cmax) ranging from 5.0 to 19.0 mg/liter. Average CFB pharmacokinetic parameters (+/- standard deviations) were as follows: apparent elimination half-life, 2.0 +/- 0.5 h; mean residence time, 3.9 +/- 1.1 h; apparent steady-state volume of distribution, 0.4 +/- 0.2 liter/kg; and apparent total plasma clearance (CL/F), 2.5 +/- 0.9 ml/min/kg. No significant differences in any of the pharmacokinetic parameters were observed between the two dosing groups. Significant (P < 0.05) negative correlations were found between patient age and CFB elimination half-life and CL/F and between the estimated creatinine clearance and renal clearance and CL/F. Apparent age dependence of CFB disposition was also reflected by a greater CL/F in children from 0.5 to less than or equal 5 years of age (3.1 +/- 1.1 ml/min/kg) than in children > 10 years of age (2.0 +/- 0.6 ml/min/kg; P < 0.005). The increased CL/f for CFB (3.0 +/- 0.5 ml/min/kg) was corroborated by a validation study performed with 11 infants (1.0 +/- 0.5 ml/min/kg) with CL/F for 19 subjects suggested that appreciable nonrenal clearance (1.3 +/- 0.6 ml/min/kg) of CFB occurred in children, a finding different from preliminary data for adults.

Abstract
STUDY OBJECTIVES To assess the reliability of the intraosseous route of administration for delivery of a loading dose of broad-spectrum antibiotics in a pediatric animal model. DESIGN Serum levels achieved within 90 minutes of equivalent intraosseous (IO) and IV bolus dosing of ceftriaxone, cefotaxime, and a combination of ampicillin and gentamicin were compared in the weanling pig. SUBJECTS Twelve female weanling pigs were studied in the Animal Facilities Laboratory at the University of Mississippi Medical Center. INTERVENTIONS Through a proximal tibial IO catheter, each anesthetized animal received one of the following: 50 mg/kg ceftriaxone, 50 mg/kg cefotaxime, or 300 mg/kg ampicillin followed immediately by 2.5 mg/kg gentamicin. Venous blood was obtained for antibiotic assay at 15, 30, 45, 60, and 90 minutes after IO injection. The animals were allowed to recover, and, after a one-week washout period, each received the same antibiotic and dose as before through a peripheral IV. Levels were assayed at the same intervals and IO versus IV were compared. MEASUREMENTS AND MAIN RESULTS Comparable serum levels of all four antibiotics were achieved by the two routes. Gentamicin levels were statistically indistinguishable IO versus IV at all assay intervals. Ampicillin and cefotaxime levels achieved by the two routes were equivalent within one hour of dosing. Serum levels of ceftriaxone after IO administration paralleled those after IV dosing but remained significantly lower at all time intervals. CONCLUSIONS In the weanling pig model, the IO route was used to deliver serum levels of broad-spectrum antibiotics comparable to those attained after IV administration. The data support the use of standard parenteral doses for IO administration. To overcome potential avid protein binding of ceftriaxone in the bone marrow, we recommend using ceftriaxone at its highest recommended IO loading dose. Consistent with many other medications that have been similarly tested, these data indicate that initial or empiric antibiotic coverage in hypodynamic and shock states in infants and young children need not await the establishment of traditional IV access.

Abstract
The study covers 78 children with typhoid fever who were hospitalized in April & May 1990. Serious complications were present in 32% (toxemia 22%, ileus 25% and myocarditis 8%). Blood cultures were positive in 30 of 49 tested. Others were diagnosed by positive Widal test. In vitro cultures of S. typhi were resistant to chloramphenicol (90%), ampicillin (93%) and co-trimoxazole (97%). However all were highly sensitive to ciprofloxacin and moderately sensitive to cephalexin and gentamycin. Ciprofloxacin alone or in combination was given in 73 of the 78 children and found to be remarkably effective in controlling the disease and preventing relapse. No serious side effects were noted. The cohort is being followed up for possible long term adverse effects.

Abstract
The single-dose pharmacokinetics of ceftizoxime sodium were studied in 52 neonates and infants between 0.1 and 189 days of age. Subjects received ceftizoxime 25 or 50 mg/kg iv over 15-30 minutes. The drug was administered q8-12h for five days to permit tolerance evaluation on repetitive dosing. No differences were observed in ceftizoxime pharmacokinetic parameter estimates relative to dose. However, marked differences were observed in ceftizoxime pharmacokinetic characteristics relative to infant age; ceftizoxime half-life and mean residence time decreased, whereas body clearance increased with infant age. Ceftizoxime volume of distribution remained relatively constant over infant age. No adverse effects associated with ceftizoxime administration were observed. These data suggest that ceftizoxime 50 mg/kg q12h be used for infants less than or equal to 2 weeks of age (less than or equal to 40 weeks postconceptional age) and that 50 mg/kg q8h be administered for older infants.

Abstract
A random selection of 25 strains isolated during an epidemic caused by serogroup A Neisseria meningitidis in Sudan (1988), 3 preepidemic meningococcal strains (1985), and 26 serogroup A strains isolated from sporadic cases of meningitis in Sweden (1973 to 1987) were assessed for multilocus enzyme genotypes (ETs), DNA restriction enzyme patterns, outer membrane proteins, lipopolysaccharides, pilus formation, and antibiograms. All of the 25 Sudanese epidemic isolates and 22 of the Swedish strains were of the same or closely related ETs (ETs 3, 4, and 5), corresponding to clone III-1, which has been responsible for two pandemic waves in the last three decades. The earlier pandemic involved Scandinavia, and the last one caused an outbreak during the pilgrimage to Mecca, Saudi Arabia (August 1987), spreading to Sudan, Chad, and Ethiopia. The three Sudanese preepidemic isolates (1985) were clone IV-1 (sulfonamide susceptible), which has been resident in the African meningitis belt for the last 25 years. The uniformity of clone III-1 strains (all sulfonamide resistant) from Sudan and Sweden was confirmed by DNA restriction enzyme patterns. ETs 3, 4, and 5 from Sudan and Sweden had 86 to 100% similarity to a Swedish clone III-1 reference strain, whereas ETs 1, 2, 6, and 7 showed 50 to 80% similarity. Class 1 protein for clone III-1 showed serosubtype antigens P1.9 and P1.x, whereas ET6 strains (clone IV-1) had serosubtype P1.7. Lipopolysaccharides were variable in the Sudanese and Swedish strains. Pili were expressed in all clone III-1 isolates from Sudan and Sweden but in none of the clone IV-1 isolates (Sudan, 1985).

Abstract
The aims of the present study were to document the epidemiology, clinical features and complications of childhood acute bacterial meningitis (ABM) in The Sudan during both an inter-epidemic (endemic) period (1985-1986), and the 1988 serogroup A epidemic; and to examine the phenotypic and genetic similarities and differences of Neisseria meningitidis strains isolated in The Sudan and Sweden. A new enzyme immunoassay test (Pharmacia Meningitis EIA-Test) was evaluated as a potential rapid diagnostic method for the detection of Haemophilus influenzae (HI) type b, Neisseria meningitidis (MC) and Streptococcus pneumoniae (PNC). The test was found to have good sensitivity (0.86) and specificity (0.95) in the inter-epidemic period; and to be adaptable to the field work in The Sudan during the 1988 MC epidemic. During inter-epidemic (endemic) situations in The Sudan, greater than 90% of childhood ABM was caused by one of the three organisms, HI type b, MC and PNC. HI accounted for 57% of the cases. The peak incidence (76%) of HI cases was in infants (less than 12 months) similar to the situation in other African countries. The overall case fatality ratio was 18.6%. Prospective follow-up of survivors for 3-4 years revealed that an additional 43% either died or had permanent neurological complications, the most prevalent and persistent of which was sensorineural hearing loss recorded in 22% of long term survivors. Post-meningitic children were found to have significantly lower intelligence quotients (92.3 +/- 13.9) than their sibling controls (100.7 +/- 10.2, P = 0.029). Features of the large serogroup A sulphonamide resistant MC epidemic (February-August 1988) in Khartoum are described. An estimated annual incidence of 1,679/100,000 was recorded at the peak of the epidemic. The highest attack rate was in young children less than 5 years, as in many other African countries; nevertheless, a high morbidity was observed in adults (31% of the cases greater than or equal to 20 years). The clinical features, mortality (6.3%) and short term sequelae in Sudanese children were generally within the framework described for MC disease elsewhere. Detailed analysis of MC isolates from Sudan and Sweden by characterizing their electrophoretic enzyme types, DNA restriction endonuclease pattern and outer membrane proteins, revealed that serogroup A MC clone III-1 was responsible of The Sudan epidemic in 1988 and has been the dominant serogroup A organism in Sweden since 1973. The Sudanese strains isolated prior to the epidemic (1985) were clone IV-1.(ABSTRACT TRUNCATED AT 250 WORDS)
