Hypertension III: Clinical Manifestations and Diagnostic Studies

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...

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Summary
This summary is machine-generated.

Daily hand trauma, like using your hand as a hammer or exposure to vibrating tools, significantly increases the risk of developing hypothenar hammer syndrome (HHS). This condition involves damage to the ulnar artery in the palm.

Area of Science:

  • Vascular Surgery
  • Occupational Health
  • Hand Surgery

Background:

  • Hypothenar hammer syndrome (HHS) is a rare condition involving ulnar artery damage.
  • It is likely caused by blunt trauma to the hypothenar region.
  • Epidemiological data on HHS are scarce, with most existing literature being case reports.

Purpose of the Study:

  • To identify risk factors associated with hypothenar hammer syndrome (HHS).

Main Methods:

  • A multicenter case-control study was conducted.
  • 71 patients diagnosed with HHS and 105 matched controls were interviewed.
  • Standardized questionnaires assessed occupational and leisure-related hand trauma, with medical records for verification.

Main Results:

  • Daily use of the hand as a hammer was a significant risk factor (aOR 17.04).
  • Daily pressure applied to the palm also increased risk (aOR 4.96).
  • Daily exposure to vibrating tools was identified as another risk factor (aOR 3.41).

Conclusions:

  • This study provides one of the largest patient cohorts for HHS to date.
  • Repeated, work-related blunt trauma to the palm is a significant risk factor for developing HHS.
