Skin Diseases and Disorders

3.9K
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...

Accessory Structures of the Skin: Nails

1.7K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

Hand hygiene

3.2K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Obsessive-Compulsive Disorder

130
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

Necrosis01:16

Necrosis

4.5K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Bone Disorders01:29

Bone Disorders

3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Summary

Onychomycosis, a common fungal nail infection, presents challenges in treatment and recurrence. Effective management involves debridement, systemic antifungals like terbinafine, and sometimes topical combinations.

Area of Science:

  • Dermatology
  • Mycology
  • Infectious Diseases

Background:

  • Onychomycosis is the most prevalent nail infection globally, characterized by nail discoloration and thickening.
  • Predominantly caused by dermatophytes, it presents with diverse clinical manifestations.
  • Accurate diagnosis via mycological examination is crucial before treatment initiation.

Purpose of the Study:

  • To review the diagnostic and management strategies for onychomycosis.
  • To highlight challenges in treatment and high recurrence rates.
  • To provide guidance on adapting therapy based on clinical factors and patient preferences.

Main Methods:

  • Literature review of diagnostic and therapeutic approaches for onychomycosis.
  • Analysis of treatment efficacy, including systemic and topical antifungal agents.
  • Evaluation of factors influencing treatment success and recurrence prevention.

Main Results:

  • Systemic treatments, particularly terbinafine, demonstrate higher efficacy than topical options for dermatophyte onychomycosis.
  • Combination therapy (systemic and topical) can improve cure rates.
  • Debridement of infected nail material is a critical initial step to reduce fungal burden.

Conclusions:

  • Nail fungal infection management requires a tailored approach, considering clinical presentation, severity, and patient history.
  • Terbinafine is a cost-effective first-line treatment for dermatophyte onychomycosis.
  • Preventative measures, including topical prophylaxis and avoiding public barefoot exposure, are important for reducing recurrence.
