Summary
This study found smaller vertebral artery (VA) diameter and flow rates on the affected side in patients with benign paroxysmal positional vertigo (BPPV). Further research with larger samples is needed to confirm these findings for BPPV diagnosis.
Area of Science:
- Vascular Neurology
- Otolaryngology
- Diagnostic Imaging
Background:
- Benign paroxysmal positional vertigo (BPPV) is a common cause of dizziness.
- The role of vascular factors in BPPV pathophysiology is not fully understood.
Purpose of the Study:
- To evaluate vertebral artery (VA) diameter and flow rates in patients diagnosed with BPPV.
- To investigate potential correlations between VA parameters and BPPV using color Doppler ultrasonography.
Main Methods:
- A cross-sectional study involving 40 patients aged 21-60 years presenting with positional dizziness.
- Clinical history, systemic, and ENT examinations were performed.
- Color Doppler ultrasound was utilized to assess vertebral artery diameter and peak systolic velocity.
Main Results:
- The mean age of participants was 56 years, with the 51-60 age group most affected.
- The most common BPPV types were right posterior (47.5%) and left posterior (30%) semicircular canal involvement.
- A statistically significant reduction in VA diameter (mean difference 0.07 cm) and peak systolic velocity (mean difference 9.9 cm/s) was observed on the BPPV-affected side.
Conclusions:
- Vertebral artery parameters showed minor decreases on the side affected by BPPV compared to the non-affected side.
- These findings suggest a potential, albeit small, vascular alteration associated with BPPV.
- Larger sample sizes are recommended to validate these results and explore their clinical significance.

6.4K
The Doppler effect and Doppler shift were named after the Austrian physicist and mathematician Christian Johann Doppler in 1842, who conducted experiments with both moving sources and moving observers. Consider an observer standing on a street corner, observing an ambulance with a siren sound passing by at a constant speed. The observer experiences two characteristic changes in the sound of the siren. Initially, the sound increases in loudness as the ambulance approaches and decreases in...

The Doppler effect has several practical, real-world applications. For instance, meteorologists use Doppler radars to interpret weather events based on the Doppler effect. Typically, a transmitter emits radio waves at a specific frequency toward the sky from a weather station. The radio waves bounce off the clouds and precipitation and travel back to the weather station. The radio frequency of the waves reflected back to the station appears to decrease if the clouds or precipitation are moving...

01:27Muscles of the Vertebral Column
3.2K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

01:28Articulations of the Vertebral Column
3.1K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
