METHODS: The recruitment of participants' was carried out at Selayang Hospital, Selangor, Malaysia. Vaginal swabs were prospectively taken from 104 patients of PPROM and 111 with spontaneous onset of labour at term. Swabs were also taken from the axillae and ears of their babies. These swabs were cultured to isolate A. baumannii. Maternal and neonatal adverse outcomes were documented.
RESULTS: Sixteen mothers were A. baumannii positive, eight from each group respectively. None of the cases developed chorioamnionitis or sepsis. Those positive were four cases of PPROM and two babies of term labour. None of the babies developed sepsis.
CONCLUSIONS: This study does not support the suggestion that A. baumannii colonisation during pregnancy is associated with adverse maternal and neonatal outcomes.
METHODS: A 'meta-model' with 4894 concentrations from 1631 neonates was built using NONMEM, and Monte Carlo simulations were performed to design an optimal intermittent infusion, aiming to reach a target AUC0-24 of 400 mg·h/L at steady-state in at least 80% of neonates.
RESULTS: A two-compartment model best fitted the data. Current weight, postmenstrual age (PMA) and serum creatinine were the significant covariates for CL. After model validation, simulations showed that a loading dose (25 mg/kg) and a maintenance dose (15 mg/kg q12h if <35 weeks PMA and 15 mg/kg q8h if ≥35 weeks PMA) achieved the AUC0-24 target earlier than a standard 'Blue Book' dosage regimen in >89% of the treated patients.
CONCLUSIONS: The results of a population meta-analysis of vancomycin data have been used to develop a new dosing regimen for neonatal use and to assist in the design of the model-based, multinational European trial, NeoVanc.
AIM: To describe demographic patterns, histopathological findings, and locations of oral and maxillofacial lesions in newborns (birth-1 month) and infants (>1 month-2 years) reported over 51 years.
DESIGN: A retrospective cross-sectional study on histopathological records of newborns and infants was conducted. Patients' demographic characteristics (age, gender, and race), histopathological diagnosis, and lesion's location were gathered. Pearson's chi-square or Fisher's exact test was performed to determine associations between demographic characteristics and different categories of lesions.
RESULTS: Out of 66,546 specimens received, 0.44% (290 specimens) were from patients aged 2 years and younger (27 newborns and 263 infants). The most common category was inflammatory/reactive (44.2%), followed by tumour/tumour-like (42.0%), cystic/pseudocystic (6.6%), and miscellaneous lesions (5.5%). Mucous extravasation cysts (23.4%) and Langerhans cell histiocytosis (7.2%) were the most common histopathological diagnoses. Tumour/tumour-like lesions were significant in newborns (P = .021), and majority were congenital epulis (40.7%). Inflammatory/reactive lesions were significantly higher in male (P = .025) and infants (P = newborns and infants are the key to early detection of lesions.
