Summary
Common comorbidities like hypertension and diabetes, along with low vitamin D levels, are linked to benign paroxysmal positional vertigo (BPPV) onset and recurrence.
Area of Science:
- Neurology
- Endocrinology
- Otolaryngology
Background:
- Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo.
- Factors influencing BPPV onset and recurrence require further investigation.
Purpose of the Study:
- To determine prevalent comorbidities in BPPV patients.
- To assess the association between serum 25-hydroxyvitamin D levels and BPPV.
Main Methods:
- Prospective, cross-sectional descriptive study.
- Inclusion of 117 patients with vertigo symptoms.
- Data collection included medical history, Dizziness Handicap Inventory, and serum 25-hydroxyvitamin D levels.
Main Results:
- Hypertension (37.6%) and type 2 diabetes mellitus (29.1%) were the most frequent comorbidities.
- Idiopathic BPPV was most common (67.5%); sudden neurosensorial hearing loss in secondary BPPV (6%).
- Mean serum 25-hydroxyvitamin D was 23.07 ng/ml, with insufficiency prevalent (42.9%).
Conclusions:
- Comorbidities and low 25-hydroxyvitamin D levels are associated with BPPV.
- These factors may contribute to BPPV onset and recurrence.
- Further prospective studies are recommended to confirm and treat these associations.

01:15Equilibrium and Balance
6.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
358
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

289
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

467
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

01:29The Vestibular System
43.4K
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.
