Diagnosis and Treatment of Fungal Diseases

Fungal diseases (mycoses) are infections caused by fungi that occur in the skin, hair, nails, or mucosal areas. Various types of fungi can lead to these diseases. Fungal infections are contagious and are particularly prevalent in warm, moist environments. In individuals with weakened immune systems, infections can be more severe.

Types and Causes of Fungal Diseases

1. Tinea (Dermatophytoses)

Tinea Capitis: Fungal infection of the scalp.
Tinea Pedis (Athlete’s Foot): A common foot infection among athletes.
Tinea Corporis: Manifests as ring-shaped lesions on different parts of the body.
Tinea Cruris: Occurs in the groin area, often triggered by sweating and moist environments.
Tinea Unguium (Onychomycosis): Fungal infection of the nails.

2. Candidiasis (Candida Infections)

Oral Candidiasis: Characterized by white lesions in the mouth and on the tongue.
Genital Candidiasis: Vaginal fungal infection in women, causing redness on the penis in men.
Cutaneous Candidiasis: Appears in skin folds.

3. Pityriasis Versicolor (Malassezia Infection)

Causes white or brown spots on the skin, commonly seen on the back, chest, and shoulders.

4. Aspergillosis and Cryptococcosis

Can lead to severe infections in immunocompromised individuals (e.g., in HIV patients or after organ transplants).

Symptoms

Itching: The most common symptom, especially in foot and groin infections.
Redness and Peeling: Dryness and flaking may occur in the infected areas.
Ring-Shaped Lesions: Common in infections like tinea corporis.
Nail Thickening and Yellowing: Deformities and color changes in nails occur in onychomycosis.
White Lesions: Characterized by white plaques in the mouth and on the tongue.
Burning and Pain: Discomfort and discharge may occur in genital fungal infections.

Diagnosis Methods

Clinical Examination: A dermatologist assesses the structure and symptoms of the infected area.
Fungal Culture: Samples are taken from the skin or nails to identify the type of fungus.
Wood’s Lamp: Used to observe fungal infections under UV light.
Microscopic Examination: Skin scrapings are examined under a microscope using KOH testing.
Blood Tests: Used to detect deep mycoses and systemic fungal infections.

Treatment Methods

1. Topical Treatments (Creams and Ointments)

Creams containing Ketoconazole, Terbinafine, Clotrimazole: Commonly used for skin and foot fungi.
Miconazole and Nystatin: Preferred for treating oral and genital candidiasis.
Salicylic Acid: Used to reduce flaking.

2. Oral Antifungal Medications
