Unrenewable Cells

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...

Auditory Pathway

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...

Hearing

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Sound Intensity Level

Sound Intensity Level

Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...

Perception of Sound Waves

Perception of Sound Waves

The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...

The Cochlea

The Cochlea

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Summary

Non-organic hearing loss (NOHL) predominantly affects young females. Discrepancies between subjective and objective hearing tests indicate NOHL, but diagnosis requires suspicion and specific testing.

Background:

Non-organic hearing loss (NOHL) presents diagnostic challenges.
Distinguishing NOHL from organic hearing loss is crucial for appropriate management.

Observation:

This study reviewed 31 patients diagnosed with NOHL.
The patient cohort consisted primarily of young females (24/31), with an average age of 16.6 years.
Symptoms and audiometric results, including both subjective and objective tests, were analyzed.

Findings:

A significant gender disparity was observed, with females constituting the majority of NOHL cases.
Discrepancies between pure tone audiometry and objective auditory testing were key indicators of NOHL.
Eight patients received steroid treatment prior to accurate NOHL diagnosis, highlighting potential diagnostic delays.

Implications:

Routine inclusion of objective audiometry is recommended to improve NOHL detection rates.
Clinicians must maintain a high index of suspicion for NOHL, especially in cases of unilateral sudden hearing loss or co-existing organic hearing impairment.
Accurate diagnosis of NOHL is essential to avoid unnecessary medical interventions and ensure appropriate patient care.
