Insights

Medical problems are common in children and teenagers with Down syndrome in Hong Kong. This study highlights the high prevalence of conditions such as cardiovascular and visual issues in this population.

Area of Science:

  • Pediatrics
  • Genetics
  • Public Health

Background:

  • Down syndrome is a genetic condition associated with an increased risk of various medical issues.
  • Understanding the specific health challenges faced by individuals with Down syndrome is crucial for effective care.

Purpose of the Study:

  • To determine the prevalence of medical problems in children and teenagers with Down syndrome in Hong Kong.
  • To provide data that can inform healthcare strategies for this population.

Main Methods:

  • A retrospective review of hospital records was conducted for 407 patients aged 0.06 to 17.16 years with Down syndrome.
  • Data were collected from seven regional hospitals in Hong Kong.

Main Results:

  • High prevalence of medical problems was observed, with cardiovascular issues (53%) and visual problems (48%) being most common.
  • Other significant conditions included endocrine problems (27%), auditory problems (34%), and gastrointestinal issues (11%).
  • Neurological (7%), skeletal (14%), sleep (9%), and haematological problems (4%) were also documented.

Conclusions:

  • The prevalence of medical problems in young individuals with Down syndrome in Hong Kong is high and consistent with international findings.
  • Further research into the medical needs of the adult Down syndrome population in Hong Kong is recommended.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Meiosis vs. Mitosis02:57

Meiosis vs. Mitosis

Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Disorders of the Male Reproductive System01:20

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
