Insights

Every child with hearing loss needs an evaluation to find the cause. This article covers non-genetic origins like neonatal intensive care, infections, and preventable factors such as ototoxic medications and noise exposure.

Area of Science:

  • Pediatrics
  • Otolaryngology
  • Genetics

Background:

  • Hearing loss affects many children.
  • Identifying the cause is crucial for treatment.
  • Non-genetic factors are significant contributors.

Purpose of the Study:

  • To review the non-genetic causes of childhood hearing loss.
  • To highlight common and preventable origins.
  • To emphasize the importance of comprehensive evaluation.

Main Methods:

  • Literature review of non-genetic hearing loss causes.
  • Focus on neonatal intensive care unit (NICU) experience.
  • Discussion of infectious and environmental factors.

Main Results:

  • Neonatal intensive care unit (NICU) experience is the most frequent non-genetic cause.
  • Meningitis, cytomegalovirus (CMV), and other infections are common causes.
  • Ototoxic medications and noise exposure are significant preventable causes.

Conclusions:

  • Non-genetic factors play a major role in childhood hearing loss.
  • Early identification of these causes is essential for intervention.
  • Preventing exposure to ototoxic drugs and excessive noise is critical.

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Unrenewable Cells00:50

Unrenewable Cells

In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.

Auditory Pathway01:15

Auditory Pathway

Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking the...
Gene-Environment Interactions01:20

Gene-Environment Interactions

Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...
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.
