Disorders of Hemostasis01:24

Disorders of Hemostasis

1.6K
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Changes in Skin Color: Clinical Perspectives

2.9K
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...

Inflammatory Bowel Disease I: Ulcerative Colitis

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Peptic Ulcer Disease I: Introduction

423
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

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...

Area of Science:

  • Pediatric Dermatology
  • Clinical Case Reports
  • Medical Diagnostics

Background:

  • Post-emetic purpura is a rare but significant cause of facial rash in children.
  • It can be misdiagnosed as more severe conditions, delaying appropriate management.
  • Understanding its unique presentation is crucial for accurate acute diagnosis.

Observation:

  • A child presented with a facial rash following multiple episodes of vomiting.
  • The child had recently been treated with trimethoprim/sulfamethoxazole for impetigo.
  • The rash's location and appearance, along with patient history, were key factors.

Findings:

  • Laboratory workup, patient history, and lesion location supported a diagnosis of post-emetic purpura.
  • The findings underscore the importance of a thorough clinical evaluation.
  • Differentiating post-emetic purpura from other purpuric eruptions is essential.

Implications:

  • Accurate diagnosis of post-emetic purpura prevents unnecessary investigations and treatments for more serious conditions.
  • Clinicians should consider post-emetic purpura in the differential diagnosis of facial rashes in children, especially after vomiting.
  • Emphasizes the need for careful history taking and physical examination in pediatric dermatology.
