Summary
Sweet's disease can cause rapid, profound sensorineural hearing loss. Cochlear implantation offers a successful treatment option when immunosuppressive therapy for this immune-mediated condition fails.
Area of Science:
- Oto-immunology
- Otolaryngology
- Dermatology
Background:
- Sweet's disease, an inflammatory dermatosis, is rarely associated with sensorineural hearing loss.
- Progressive, bilateral sensorineural hearing loss can complicate autoimmune conditions.
Observation:
- A case of Sweet's disease presented with acute, severe hearing impairment.
- Clinical presentation mimicked immune-mediated inner ear disease, complicating diagnosis.
Findings:
- Diagnosis was challenging due to the lack of specific biomarkers for immune-mediated inner ear disease.
- The patient did not respond to immunosuppressive treatments for the hearing loss.
Implications:
- Sensorineural hearing loss in Sweet's disease may stem from immunological factors.
- Cochlear implantation provides a viable alternative for hearing restoration when medical treatments are ineffective.

Diabetic Neuropathy
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
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...

Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
Pleiotropy
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,...
Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
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.
