Skin Diseases and Disorders

5.4K
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...

Atypical Pneumonia01:14

Atypical Pneumonia

84
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

Fungal Phylum Ascomycota01:28

Fungal Phylum Ascomycota

2.4K
Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

Skin Cancer01:30

Skin Cancer

5.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Antifungal Agents01:15

Antifungal Agents

119
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to...

Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

1.8K
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Summary
This summary is machine-generated.

Diagnosing dermatophyte infections can be challenging due to atypical presentations (tinea atypica) and misdiagnosis, leading to delayed recovery. Understanding morphological variations and risk factors is key for accurate diagnosis and effective treatment.

Area of Science:

  • Dermatology
  • Medical Mycology

Background:

  • Dermatophyte infections, though often straightforward, are frequently misdiagnosed.
  • Atypical presentations (tinea atypica) can mimic other skin conditions due to pathogen characteristics and patient factors like hygiene or sun exposure.
  • Improper treatment, such as steroid prescriptions, can lead to pathomorphosis (tinea incognito), prolonging illness.

Purpose of the Study:

  • To review the morphology of atypical dermatophyte infections.
  • To correlate morphological changes with disease site and predisposing factors.
  • To enhance diagnostic suspicion in challenging cases.

Main Methods:

  • Literature review focusing on morphology of atypical dermatophyte infections.
  • Analysis of risk factors and predisposing conditions.
  • Comparison of atypical features with typical presentations.

Main Results:

  • Dermatophyte morphology varies significantly based on site and patient-specific conditions.
  • Misdiagnosis and inappropriate treatments contribute to disease pathomorphosis and delayed healing.
  • Understanding these variations aids in identifying atypical cases.

Conclusions:

  • Accurate diagnosis of dermatophyte infections requires recognizing atypical presentations and understanding contributing factors.
  • Continuous training is essential for dermatologists to improve diagnostic skills for tinea atypica.
  • Early and correct diagnosis leads to appropriate treatment and better patient outcomes.
