Insights

Obstructive sleep apnea syndrome (OSAS) risk affects 9.5%-13.6% of children with cleft lip/palate in Hong Kong. Clefts involving the embryonic secondary palate increase this risk, suggesting a need for multimodal assessment.

Area of Science:

  • Pediatric pulmonology
  • Craniofacial anomalies
  • Sleep medicine

Background:

  • Cleft lip and/or palate (CL/P) can lead to craniofacial abnormalities affecting airway development.
  • Obstructive sleep apnea syndrome (OSAS) is a potential complication in children with CL/P, but prevalence data in Hong Kong is limited.

Purpose of the Study:

  • To determine the prevalence of OSAS risk in Hong Kong children and adolescents with CL/P.
  • To identify risk factors associated with OSAS in this population.

Main Methods:

  • A retrospective survey study involving 351 children and adolescents (6-18 years) with non-syndromic CL/P.
  • Utilized OSA-18, PSQ-22, and modified ESS questionnaires to assess OSAS risk.
  • Analyzed age, sex, overweight, cleft type, and surgical history as potential risk factors.

Main Results:

  • OSAS risk prevalence ranged from 9.5% (OSA-18) to 13.6% (PSQ-22).
  • Higher OSAS risk was associated with younger age, clefts involving the embryonic secondary palate, and prior orthodontic treatment.
  • Embryonic secondary palate involvement was the only significant risk factor identified (OR=3.7, p=0.015).

Conclusions:

  • OSAS risk affects a notable percentage of children with CL/P in Hong Kong.
  • Clefts involving the embryonic secondary palate are a key risk factor for OSAS in this group.
  • A multimodal approach is recommended for OSAS risk assessment in children with CL/P.

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Chronic Obstructive Pulmonary Disease01:22

Chronic Obstructive Pulmonary Disease

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...
