Summary
Torticollis can signal rare craniovertebral junction (CVJ) abnormalities. This study highlights nontraumatic CVJ issues in 27 patients, aiding clinicians in diagnosing torticollis causes.
Area of Science:
- Neurology
- Orthopedics
- Radiology
Background:
- Torticollis can be the sole indicator of craniovertebral junction (CVJ) abnormalities.
- Identifying nontraumatic CVJ abnormalities as a cause of torticollis is challenging due to their rarity.
Purpose of the Study:
- To report 27 patients with torticollis caused by nontraumatic CVJ abnormalities.
- To assist clinicians in recognizing nontraumatic CVJ abnormalities as a potential cause of torticollis.
Main Methods:
- Retrospective cohort study of 27 patients with torticollis due to nontraumatic CVJ abnormalities.
- Evaluation of CVJ parameters: atlanto-occipital angle, atlanto-axial angle, and atlanto-dens intervals.
- Assessment for occipital condylar hypoplasia, atlanto-axial joint rotation, and lateral/anterior dens displacement.
Main Results:
- Occipital condylar hypoplasia, atlanto-axial joint rotation, and lateral dens shift were the most frequent CVJ abnormalities.
- 18.5% of patients had concurrent lower cervical or thoracic vertebral anomalies.
- Patients presented with an average of 2.22 ± 1.10 types of CVJ abnormalities.
Conclusions:
- Comprehensive CVJ evaluation is recommended for diagnosing unexplained torticollis.
- Concurrent vertebral anomalies should be assessed once CVJ abnormalities are identified.

02:23Abnormal Proliferation
5.2K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

01:11P-N junction
1.3K
A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.

01:19The Neuromuscular Junction
19.4K
The nervous system consists of complex motor neuron circuits, including upper motor neurons originating from the cerebral cortex and lower motor neurons starting in the spinal cord, coordinating both voluntary and involuntary movements. Among these, somatic motor neurons activate skeletal muscles and are classified into alpha, beta, and gamma types. Alpha neurons are vital for voluntary movement coordination, while gamma neurons adjust muscle spindle sensitivity, and the function of beta...

01:03Anchoring Junctions
5.0K
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...
