Cardiovascular System Abnormal Findings I: Inspection and Palpation

Cardiovascular System Abnormal Findings I: Inspection and Palpation

In a cardiovascular examination, inspection and palpation are crucial for identifying abnormalities.
Abnormal findings observed during an inspection

Assessment of the Cardiovascular System III: Palpation

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

Assessment of the Cardiovascular System II: Inspection

Assessment of the Cardiovascular System II: Inspection

Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

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...

The Vestibular System

The Vestibular System

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.

Equilibrium and Balance

Equilibrium and Balance

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...

Summary

Systemic sclerosis (SSc) patients show evidence of vestibular dysfunction, which is linked to microvascular changes. This finding highlights the impact of SSc on the vestibular system and its correlation with vascular severity.

Background:

Systemic sclerosis (SSc) is a complex autoimmune disease characterized by widespread microvascular damage and fibrosis.
Vestibular dysfunction can significantly impact patient quality of life, yet its prevalence in SSc is not well-defined.

Purpose of the Study:

To investigate the prevalence of vestibular dysfunction in patients with SSc.
To explore the correlation between vestibular impairment and clinical disease parameters, including microvascular involvement.

Main Methods:

Computerized dynamic platform posturography (CDP) was used to assess vestibular function in 30 SSc patients and 29 healthy controls.
Nailfold videocapillaroscopy (NVC) was employed to evaluate microvascular status.
Clinical and instrumental investigations assessed disease parameters like skin, lung, and renal involvement.

Main Results:

Subtle vestibular dysfunction was identified in 33% of SSc patients, with significantly lower vestibular ratio values compared to controls (P=0.01).
Vestibular affection showed a significant association with Rodnan's skin score and vascular severity score.
A significant correlation was observed between vestibular dysfunction and NVC patterns, indicating microvascular involvement.

Conclusions:

The study provides evidence of vestibular impairment in SSc patients.
Vestibular dysfunction in SSc is positively correlated with vascular severity, as assessed by NVC.
