Summary
Vitiligo patients often experience hearing loss and auditory system changes, indicating it
Area of Science:
- Dermatology
- Otolaryngology
- Genetics
Background:
- Vitiligo is characterized by melanocyte loss, a mechanism yet to be fully understood.
- Melanocytes are present in the auditory system, suggesting potential vitiligo-related auditory involvement.
- Vitiligo is increasingly recognized as a systemic condition affecting more than just the skin.
Purpose of the Study:
- To investigate the prevalence of auditory alterations in individuals diagnosed with vitiligo.
- To determine if vitiligo impacts the auditory system.
Main Methods:
- Pure tone audiometry (PTA) was performed on all participants.
- Auditory brainstem responses (ABR) were measured in patients and controls.
- A cohort of 21 vitiligo patients was compared with 20 healthy controls.
Main Results:
- High-frequency sensorineural hearing loss was observed in 38.09% of vitiligo patients.
- Abnormal auditory brainstem response (ABR) findings included increased Wave III latency (47.61%) and prolonged Wave I-III interpeak latency (28.57%).
- No correlation was found between age, disease duration, and auditory parameters.
Conclusions:
- The auditory system is implicated in vitiligo.
- Vitiligo should be considered a systemic disease with potential audiological manifestations.
- Further research is warranted to explore the link between vitiligo and hearing impairment.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:19Type I Diabetes III: Clinical Manifestations
26
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the...

31.2K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

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...
