Summary
Tinea versicolor commonly affects young adults, appearing on the neck, chest, and back, often worsening in summer. Controlling predisposing factors is key to managing this persistent fungal infection.
Area of Science:
- Dermatology
- Mycology
- Epidemiology
Background:
- Tinea versicolor is a common superficial fungal infection.
- Understanding its clinical features and risk factors is crucial for effective management.
Purpose of the Study:
- To investigate the clinical characteristics, age and sex distribution, and associations with climate and personal habits in tinea versicolor patients.
- To identify factors contributing to treatment resistance.
Main Methods:
- A study of 120 patients with tinea versicolor attending a dermatology outpatient department.
- Data collection on clinical presentation, demographics, climate, personal habits, and medical history.
Main Results:
- The infection was most prevalent in the 21-30 age group (30%) and commonly affected the neck (71.6%), back (70%), and chest (58.3%).
- Lesions often appeared and worsened during summer months.
- A significant proportion of patients had underlying systemic diseases, were on immunosuppressants, or had a positive family history (38.3%).
- Treatment resistance was observed in 21.6% of patients.
Conclusions:
- Tinea versicolor exhibits distinct clinical patterns and is influenced by environmental and personal factors.
- Management should focus on addressing predisposing factors such as excessive sweating, poor hygiene, malnutrition, and synthetic clothing.
- While treatment can be challenging, lifestyle modifications are essential for controlling the disease.

01:14Changes 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.

01:23Skin 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.

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:15Antifungal Agents
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 cholesterol contributes to...
01:16Clinical Trials
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

01:20Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
