Summary
Some vestibular schwannomas spontaneously involute, with an 8% incidence and 50% average regression. However, tumor shrinkage does not prevent hearing loss in patients under observation.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- Vestibular schwannomas typically exhibit stable growth or progression.
- Spontaneous tumor involution is rarely reported but documented.
Purpose of the Study:
- To describe clinical and radiological features of vestibular schwannomas with spontaneous involution.
- To assess the incidence and characteristics of tumor regression in vestibular schwannomas.
Main Methods:
- Retrospective analysis of 14 patients with vestibular schwannoma.
- Clinical and radiological data collection during observational follow-up.
Main Results:
- An 8% incidence of spontaneous vestibular schwannoma involution was observed.
- Average tumor regression was 50% among affected patients.
- All patients experienced hearing loss, irrespective of follow-up duration.
Conclusions:
- Spontaneously involutive vestibular schwannomas exist but do not preclude hearing deterioration.
- Hearing loss progression is independent of tumor regression in these cases.
- Patients with involutive vestibular schwannomas may represent a distinct subgroup for observational management.

Spontaneity
30.0K
A spontaneous process is one that occurs naturally under certain conditions. A nonspontaneous process, on the other hand, will not take place unless it is “driven” by the continual input of energy from an external source. Processes have a natural tendency to occur in one direction under a given set of conditions. Water will naturally flow downhill (spontaneous process), but uphill flow (nonspontaneous process) requires outside intervention such as the use of a pump. Iron exposed to...

The Vestibular System
43.9K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Spontaneous and Induced Mutations
2.3K
Spontaneous mutations arise infrequently during DNA replication due to errors in the process. A key factor behind these errors is tautomeric shifts in nitrogenous bases, where bases transition from keto to enol forms or amino to imino forms. This shift can alter base-pairing rules, leading to mutations. Additionally, reactive oxygen species (ROS) arising from aerobic metabolism can damage DNA, resulting in depurination (loss of a purine base) or depyrimidination (loss of a pyrimidine base).

What is a Sensory System?
101.1K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

Effects of Temperature on Free Energy
28.3K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

Second Law of Thermodynamics
27.1K
In the quest to identify a property that may reliably predict the spontaneity of a process, a promising candidate has been identified: entropy. Processes that involve an increase in entropy of the system (ΔS > 0) are very often spontaneous; however, examples to the contrary are plentiful. By expanding consideration of entropy changes to include the surroundings, a significant conclusion regarding the relation between this property and spontaneity may be reached. In thermodynamic models, the...
