Summary
Acute sensorineural hearing loss in patients with leukemia or aplastic anemia can stem from sudden hearing loss or endolymphatic hydrops. The inner ear
Area of Science:
- Otorhinolaryngology
- Hematology
- Neurotology
Background:
- Hematological disorders like leukemia and aplastic anemia can present with acute sensorineural hearing loss.
- Investigating the inner ear's involvement is crucial for understanding hearing deficits in these patients.
Observation:
- A 20-year study examined 14 patients with hematological disorders and acute sensorineural hearing loss.
- An inner ear test battery included audiometry, cervical vestibular-evoked myogenic potential (cVEMP), ocular VEMP (oVEMP), and caloric tests.
Findings:
- Diagnoses included sudden sensorineural hearing loss (12 patients) and endolymphatic hydrops (4 patients).
- Significant declines in cochlear, saccular, utricular, and semicircular canal function were observed, with the pars inferior being more affected.
Implications:
- Acute sensorineural hearing loss in hematological disorders may indicate sudden sensorineural hearing loss or endolymphatic hydrops.
- The pars inferior of the inner ear appears more susceptible to hematological insults than the pars superior.

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...

01:01Regulation of Hematopoietic Stem Cells
4.5K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

2.9K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...
