Abstract

Insights

Venous insufficiency (VI) is a significant cause of pigmented purpuric dermatosis (PPD). This study found a strong correlation between VI and PPD, suggesting VI provokes PPD development.

Area of Science:

  • Dermatology
  • Vascular Medicine

Background:

  • Pigmented purpuric dermatosis (PPD) is a chronic skin condition with unclear etiology.
  • Previous research suggests a potential link between PPD and venous insufficiency (VI), but this relationship requires further clarification.

Purpose of the Study:

  • To investigate the causal relationship between PPD and VI.
  • To determine if VI is a contributing factor in the development of PPD.

Main Methods:

  • Retrospective review of 118 PPD patients.
  • Doppler ultrasonography of lower extremities in 56 PPD patients to assess for VI.
  • Comparison of clinical features between PPD patients with and without VI.
  • Analysis of laterality and distribution correlation between PPD and VI.

Main Results:

  • Venous insufficiency (VI) was identified in 62.5% of PPD patients studied.
  • PPD patients with VI exhibited wider lesion distribution, darker pigmentation, and longer disease duration.
  • A positive correlation was observed between the laterality of PPD and VI, as well as PPD distribution and affected veins.

Conclusions:

  • The findings strongly suggest that venous insufficiency (VI) acts as a provoker for pigmented purpuric dermatosis (PPD).
  • This study establishes a clear link between VI and PPD, highlighting VI as a key factor in PPD pathogenesis.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Varicose Veins I: Introduction

Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...

Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Assessment of the Cardiovascular System III: Palpation01:27

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...
