Insights

Children with Down syndrome experience more ear abnormalities, including impacted wax, retracted eardrums, middle ear effusion, and auditory canal stenosis, compared to healthy children in Malaysia.

Area of Science:

  • Otolaryngology
  • Pediatrics
  • Genetics

Background:

  • Down syndrome is associated with various health complications.
  • Otological abnormalities are frequently observed in children with Down syndrome.

Purpose of the Study:

  • To determine the prevalence of otological abnormalities in Malaysian children with Down syndrome.
  • To compare otological findings between children with Down syndrome and their healthy peers.

Main Methods:

  • Otoscopic examination and impedance audiometry were performed on 30 children with Down syndrome and a control group.
  • Data was collected at the ENT outpatient clinic of University Hospital, Kuala Lumpur.

Main Results:

  • Children with Down syndrome exhibited significantly higher rates of impacted wax (44% vs. 14.4%), retracted eardrums (21% vs. 6.6%), and middle ear effusion (15% vs. 3.4%).
  • Type B tympanograms (55% vs. 8.3%) and auditory canal stenosis (73.4% vs. 14.4%) were also more prevalent in the Down syndrome group.

Conclusions:

  • Children with Down syndrome have a substantially higher incidence of otological disorders.
  • These findings highlight the need for routine otological screening in children with Down syndrome.

Meiosis I03:20

Meiosis I

Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by a...
Nondisjunction02:14

Nondisjunction

During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.When...
Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.
Diagnostic Criteria and...
Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
Sex Linked Disorders02:28

Sex Linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.Y chromosome mutations are called “Y-linked” and only affect males since they alone carry a copy of that chromosome. Mutations to the relatively small Y chromosome can impact male sexual function and secondary sex characteristics. Y-chromosome infertility is a disorder that affects sperm...
