With recognition of the importance of obstructive sleep apnea syndrome (OSAS) in children, practice guidelines have been developed for the management of OSAS in the USA and Europe. A panel of experts in pediatric OSAS in Asia were appointed by the Asian Paediatric Pulmonology Society (APPS) to prepare a position statement for management of childhood OSAS in Asia. The purpose of this statement is to provide a reference standard in the diagnosis and management of childhood OSAS for doctors working in Asia. The expert panel determined the scope of this statement. Focused literature search related to the key topics was conducted by panel members. The final content of this statement was agreed on by all panel members and approved by the council of APPS. The current statement covered diagnostic approach, diagnostic criteria, management algorithm, drug-induced sleep endoscopy, medical treatment including medications and positive pressure ventilation, surgical treatment including adenotonsillectomy, orthodontic treatment, and orofacial myofunctional therapy (OMT). Diagnostic criteria of childhood OSAS from 1 year to 18 years were presented that include both clinical (criteria A) and polysomnography findings (criteria B) in the diagnosis of childhood OSAS. The use of nocturnal pulse oximetry as a screening tool was suggested using the McGill oximetry score. Management of OSAS with medical treatment, tonsillectomy and adenoidectomy (TandA), positive airway pressure, orthodontic devices, nasal valves, and OMT were reviewed. Management of persistent OSAS after TandA was addressed, and the importance of weight control was emphasized. The position statement provides a guideline to the management of childhood OSAS in Asia.

Context: Viruses are the main causes of acute lower respiratory tract infections (ALRIs) in childhood and its impact on hospital admission is largely unknown. Aims: The aim of this study is to determine (a) virus detection, (b) risk factors for admission, particularly virus detection, and (c) differential clinical responses to viral infections, in children attending pediatric emergency department (PED) with an ALRI in Malaysia. Subjects and Methods: This prospective study included children ≤2 years who presented to PED between September 1, 2010, and March 6, 2012, with features of lower respiratory tract infection. Nasopharyngeal aspirates (NPAs) were tested using a multiplex polymerase chain reaction (PCR) for 11 respiratory viruses. Results: Two hundred children were recruited in the study. Two-thirds (65.5%) of them were admitted. NPA-PCR was positive in 54% of all patients: 50.4% of those admitted and 60.9% of those discharged. The most common viruses detected were respiratory syncytial virus (RSV) (49.1%), rhinovirus (30.6%), and parainfluenza viruses (12.0%). Five patients had mixed infections. RSV detection was associated with previous history of wheeze (odds ratio, 2.05 [95% confidence interval 1.06, 4.00]). Viruses were detected in all severely ill patients and patients with apnea. Multivariate analysis showed that virus detection was not associated with the need for admission, but female sex, lack of breastfeeding and, attending nursery were associated with hospitalization. Conclusions: Half of the children who presented to the emergency room with ALRI had viruses detected in their NPA. There was no association between virus detection and hospitalization. RSV was associated with history of wheeze. Female gender, lack of breastfeeding, and nursery attendance were associated with hospitalization.

This report reviews the historical developments leading to recognition of pediatric obstructive sleep apnea. It briefly summarized the rationale why the upper airway becomes at risk of collapsibility during sleep. It also reviews the complaints that vary with age. It emphasizes points of the examination that must be systematically look for. The report reviews the variables to monitor, to look for, and to be analyzed, and patterns not often looked at but that disturb sleep and lead to complaints and symptoms in sleep polysomnography.
