Utility of overnight oximetry indices in the evaluation of children with snoring and suspected obstructive sleep apnea.

Study Objectives: Optimal cutoff values of oximetry indices that differentiate obstructive sleep apnea (OSA) from primary snoring (PS) are not well-established. Our study aimed to assess the utility of overnight oximetry indices in differentiating PS from OSA and assessing OSA severity, compared to polysomnography, in children with suspected OSA.

Methods: This was a retrospective study of children (1-18 years of age) with snoring who underwent polysomnography.

Breastfeeding Practices and Postpartum Weight Retention in an Asian Cohort.

This study examines relationships between breastfeeding practices and postpartum weight retention (PPWR) at 6 and 12 months postpartum among 379 first-time mothers participating in a clinical trial in Singapore. We categorized feeding modes at 6 months into exclusive breastfeeding, mixed feeding, and exclusive formula feeding. Participants were analyzed in two groups based on their PPWR assessment at 6 and 12 months postpartum, with complete datasets available for each assessment.

Profile of hospitalised maltreated children aged 0 to 3 years and their families.

Introduction: Maltreatment adversely affects children's health and development. Knowledge of child maltreatment in early childhood is limited. We studied the demographic factors and health issues in children aged 0-3 years who were hospitalised for maltreatment.

A Community-enabled Readiness for first 1000 Days Learning Ecosystem (CRADLE) for first-time families: study protocol of a three-arm randomised controlled trial.

Background: Enhanced parenting self-efficacy (PSE) contributes to positive parenting and future parental-child health. First-time parents, in particular, are in need of support since the pregnancy until post-delivery to strengthen their early PSE. However, there is a lack of effective and sustainable relevant programmes in the community.

Concordance between bronchial hyperresponsiveness, fractional exhaled nitric oxide, and asthma control in children.

Background: Previous studies on association between level of asthma control, markers of airway inflammation and the degree of bronchial hyperresponsiveness (BHR) have yielded conflicting results. Our aim was to determine the presence and severity of BHR and the concordance between BHR, asthma control, and fractional exhaled nitric oxide (FeNO) in children with asthma on therapy.

Methods: In this cross-sectional observational study, children (aged 6-18 years) with asthma on British Thoracic Society (BTS) treatment steps 2 or 3, underwent comprehensive assessment of their asthma control (clinical assessment, spirometry, asthma control test [ACT], Pediatric Asthma Quality of Life Questionnaire [PAQLQ]), measurement of FeNO and BHR (using mannitol dry powder bronchial challenge test [MCT], Aridol™, Pharmaxis, Australia).

Pilot study of the use of Yin Qiao San in children with conventional antipyretic hypersensitivity.

Background: Children with a diagnosis of cross-reactive hypersensitivity to both paracetamol and nonsteroidal anti-inflammatory drugs are limited in their choice of antipyretics.

Objective: The aim of this pilot study is to evaluate the feasibility of using a Chinese proprietary medicine, Yin Qiao San (YQS), for fever relief.

Methods: A single centre, open label, prospective clinical trial exploring the tolerability and feasibility of using YQS for fever relief in children who are unable to use conventional antipyretic medications.

An independent association of prenatal depression with wheezing and anxiety with rhinitis in infancy.

Background: Different maternal psychological states during pregnancy have been associated with wheeze-rhinitis-eczema symptoms in children. However, previous studies were limited and it was unclear whether the type of prenatal psychological state was associated with a particular symptom. We examined the association of maternal depression and anxiety during pregnancy with wheeze-rhinitis-eczema symptoms in infancy.

Compliance with noninvasive home ventilation in children with obstructive sleep apnoea.

Introduction: This study aimed to determine compliance with noninvasive home ventilation in children with obstructive sleep apnoea and the factors affecting this compliance.

Methods: We retrospectively reviewed 51 children who were prescribed noninvasive home ventilation for the management of obstructive sleep apnoea from 1 January 2000 until 31 May 2008. Noninvasive ventilation was started based on positive polysomnogram, i.

Paediatric anaphylaxis in a Singaporean children cohort: changing food allergy triggers over time.

Background: We have noticed changes in paediatric anaphylaxis triggers locally in Singapore.

Objective: We aimed to describe the demographic characteristics, clinical features, causative agents and management of children presenting with anaphylaxis.

Methods: This is a retrospective study of Singaporean children presenting with anaphylaxis between January 2005 and December 2009 to a tertiary paediatric hospital.

Allergic rhinitis and non-allergic rhinitis in children in the tropics: prevalence and risk associations.

Background: The age-related comparative prevalence of allergic rhinitis (AR) and non-allergic rhinitis (NAR) in children is poorly defined. We aimed to characterize AR and NAR in children.

Methods: This study enrolled children with chronic rhinitis who presented to a tertiary paediatric center for a diagnostic skin prick test (SPT).

Efficacy of metered-dose inhalers for children with acute asthma exacerbations.

Objective: To compare the effectiveness of the administration of inhaled beta-agonists delivered via a metered-dose inhaler (MDI) with spacers--as part of an evidence-based asthma pathway developed to manage acute asthma exacerbations in children at the emergency room level and in inpatient management--against administration via nebulization.

Design: Case with historical control.

Setting: KK Women's and Children's Hospital (Singapore).

Pediatric Flexible Bronchoscopy in Singapore: A 10-year Experience.

Aim: To determine the results of children who underwent flexible bronchoscopy and bronchoalveolar lavage (BAL) in the Respiratory Medicine Service of Kandang Kerbau Women's and Children's Hospital from 1996 to 2005.

Method: This was a retrospective study of all patients who underwent flexible bronchoscopy. Patients were traced from the hospital records.

Influenza vaccine concurrently administered with a combination measles, mumps, and rubella vaccine to young children.

Children aged 11 to <24 months received 2 intranasal doses of live attenuated influenza vaccine (LAIV) or placebo, 35+/-7 days apart. Dose 1 was administered concomitantly with a combined measles, mumps, and rubella vaccine (Priorix). Seroresponses to measles and mumps were similar between groups.

Hypersensitivity to paracetamol in Asian children with early onset of nonsteroidal anti-inflammatory drug allergy.

Background: The published incidence of paracetamol cross-reactivity in adults and adolescents with nonsteroidal anti-inflammatory drug (NSAID) reactions is low and all data on such reactions in young children is sparse. The study aim was to characterize the clinical presentation and cross-reactivity with paracetamol in patients with a reported onset of NSAID hypersensitivity before 6 years of age.

Methods: A retrospective case review was done of patients with cross-reactive hypersensitivity reactions to antipyretic/analgesic medications from the pediatric allergy clinic of the Kendang Kerbau Hospital, Singapore.

Is the childhood asthma questionnaire a good measure of health-related quality of life of asthmatic children in Asia?: validation among paediatric patients with asthma in Singapore.

Background: Health-related quality of life (HR-QOL) is an important outcome in the treatment of chronic childhood diseases such as asthma. However, this measure is rarely used in young children in Asia because of the difficulty of obtaining valid, reliable instruments that are developmentally and culturally suitable.

Objectives: To select, culturally adapt and validate a disease-specific HR-QOL questionnaire (Childhood Asthma Questionnaire [CAQ]-B) for asthmatic children aged 7-11 years in Singapore, and to understand the relationship between patient-reported HR-QOL domains and physician- or caregiver-rated severity.

Early presentation with angioedema and urticaria in cross-reactive hypersensitivity to nonsteroidal antiinflammatory drugs among young, Asian, atopic children.

Objective: Nonsteroidal antiinflammatory drugs (NSAIDs), mainly ibuprofen, are used extensively among children as analgesic and antipyretic agents. Our initial survey in the Kendang Kerbau Children's Hospital in Singapore showed NSAIDs to be the second most common adverse drug reaction-causing medications among children of Asian descent. We attempted to characterize the clinical and epidemiologic profile of NSAID reactions in this group of patients.

Bimodal skin reactivity to histamine in atopic children in Singapore: influence of specific sensitizations.

Histamine skin prick test (SPT) is used as the 'golden standard' for positive control in in vivo immediate type hypersensitivity testing. The skin reactivity to histamine can, however, be modulated by a bevy of extraneous factors. We aimed to define whether histamine skin reactivity in atopic children in Singapore is influenced by age, ethnic origin, gender, environmental exposure or specific sensitization patterns.
