Abstract This study investigates the spatial characteristics of nonzero rain rates to develop a probability density function (PDF) model of precipitation using rainfall data from the Tropical Rainfall Measuring Mission (TRMM) satellite. The minimum χ2 method is used to find a good estimator for the rain-rate distribution between the gamma and lognormal distributions, which are popularly used in the simulation of the rain-rate PDF. Results are sensitive to the choice of dynamic range, but both th

Bacterial meningitis remains a serious cause of morbidity and mortality in childhood. Epidemiologic investigations have shown variability in disease risks among different populations and races. In Korea, however, basic epidemiologic information on bacterial meningitis in children is limited. The main purpose of this study was to analyze bacteriologically proven meningitis cases in terms of the relative frequency of causative organisms, mortality rate, and age distribution beyond the neonatal per

BACKGROUND AND OBJECTIVES: The goal of this meta-analysis study was to perform a systematic review of the literature on the effects of ketamine on postoperative pain following tonsillectomy and adverse effects in children. SUBJECTS AND METHODS: Two authors independently searched three databases (MEDLINE, SCOPUS, Cochrane) from their inception of article collection to February 2014. Studies that compared preoperative ketamine administration (ketamine groups) with no treatment (control group) or o

OBJECTIVES/HYPOTHESIS: The objective of this study was to perform a meta-analysis of the efficacy of honey in the management of oral mucositis during radiotherapy in patients with head and neck cancer. STUDY DESIGN: Meta-analysis using MEDLINE, Scopus, and the Cochrane Library as data sources. METHODS: Two authors independently searched the databases for relevant studies from inception to June 2014. Included in the meta-analysis were randomized controlled studies published in English comparing t

Abstract Four years of outgoing longwave radiation (OLR) and rainfall data from the Tropical Rainfall Measuring Mission (TRMM) are investigated to find the dominant large-scale wave modes in the Tropics. By using space– time cross-section analysis and spectral analysis, the longitudinal and latitudinal behaviors of the overall waves and the dominant waves are observed. Despite the noisy nature of precipitation data and the limited sampling by the TRMM satellite, pronounced peaks are found for Ke

Bacterial meningitis remains a serious cause of morbidity and mortality in childhood,despite the availability of effective vaccines against Haemophilus influenzae type b (Hib) or Streptococcus pneumoniae. The purpose of this study was to analyze data on bacterial meningitis cases in Korea from 1996 through 2005. The information of all hospitalized bacteria-proven meningitis cases was obtained from 17 university hospitals nationwide. A total of 402 cases were identified. Of these, 125 (29.9%)case

OBJECTIVES: Acupuncture has been shown to reduce pain, nausea, and vomiting. However, its use alongside surgical interventions remains a novel practice, despite the increasing applications of alternative medicine. The goal of this meta-analysis was to perform a systematic review of the literature addressing the effect of acupuncture on postoperative pain, nausea, and vomiting following tonsillectomy. DATA SOURCES: MEDLINE, SCOPUS, and Cochrane database. METHODS: Two authors independently searche

Because EV71 causes severe complications and death in children, a surveillance system to predict upcoming outbreaks should be established and maintained and adequate public health measures are needed to control disease.

OBJECTIVES: This study aimed to assess the effects of perioperative dexmedetomidine as an adjuvant to tonsillectomy compared with opioid or sham in children. DATA SOURCE: Five databases (PubMed, SCOPUS, Embase, Web of Science, and Cochrane Central Register of Controlled Trials) were searched from inception of article collections to April 2017. REVIEW METHODS: Prospective, randomized controlled studies that compared outcomes between children who underwent tonsillectomy plus dexmedetomidine admini

Mycoplasma pneumoniae (MP) is the most common cause of childhood bacterial pneumonia. Although macrolide is known to be effective as a first-line therapy, the proportion of macrolide resistance in MP pneumonia has strikingly increased during recent 2 decades in East Asia. This is challenging to physicians since they have to decide more often whether to use secondary treatment. Diagnostic methods to detect macrolide-resistance of MP are currently not available in Korean hospitals. Even in the dia

In this study, the seroprevalences of measles, mumps, and rubella antibodies in infants were determined to assess the immunization strategy and control measures for these infectious diseases. Serum samples from infants < 1 year of age and their mothers were collected to measure the concentrations of specific IgG antibodies to measles, mumps, and rubella by enzyme-linked immunosorbent assay. For selected infant serum samples, measles-specific neutralizing antibody levels were determined by using

Severe congenital neutropenia (SCN) is a heterogeneous group of disorders with a defect in granulopoiesis causing marked neutropenia and severe bacterial infections. A 17-month-old girl (patient 1) was admitted due to cervical lymphadenitis caused by methicillin-resistant Staphylococcus aureus, with neutropenia. She had Pseudomonas aeruginosa sepsis and peritonitis with perforated appendicitis at 8-month of age. Her sister, a 37-month-old girl (patient 2), had recurrent stomatitis with profound

Objectives The perioperative administration of magnesium is known to reduce postoperative morbidities in adults, such as pain, agitation, and laryngospasm. The objective is to assess the effects of perioperative magnesium as the adjuvant to tonsillectomy as compared with tonsillectomy in children. Data Source Five databases (PubMed, SCOPUS, Embase, Web of Science, Cochrane). Method Two authors independently searched databases up to January 2017. We compared perioperative magnesium administration

Pregnant individuals and infants are at risk from vaccine-preventable diseases like severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza. Maternal vaccination during pregnancy can protect both the mother and child. Recent progress in developing these vaccines is notable, but vaccine hesitancy and the exclusion of pregnant individuals from clinical trials limit their use. Maternal immunization safeguards mothers from severe illness and adverse pregnancy outcomes while provid
