Tinea Versicolor

Tinea versicolor, also known as pityriasis versicolor, is a chronic superficial fungal infection of the skin caused by the Malassezia species—a lipophilic yeast that is part of the normal skin flora. This condition leads to discolored patches on the skin, often resulting in cosmetic concerns, especially in individuals with darker skin tones or during warmer

Tinea Pedis

Tinea pedis, commonly known as athlete’s foot, is a contagious fungal infection affecting the feet, particularly the interdigital spaces, soles, and sides. It is one of the most prevalent dermatophytoses worldwide, caused by fungi that thrive in warm, moist environments. Despite being treatable, it often recurs without proper management and hygiene. Etiology: What Causes Tinea

Tinea Manuum

Tinea manuum is a superficial dermatophyte infection that affects the palms, fingers, and interdigital spaces of the hands. Often referred to as ringworm of the hand, this condition results from dermatophyte fungi and can appear unilaterally, commonly affecting the dominant hand. It is frequently associated with concurrent infections like tinea pedis (athlete’s foot) or onychomycosis

Tinea Cruris

Tinea cruris, commonly known as jock itch, is a superficial fungal infection affecting the groin, inner thighs, and buttocks. Caused by dermatophyte fungi, this infection thrives in warm, moist environments and is particularly prevalent among men, athletes, and individuals living in tropical climates. It is highly contagious and can significantly impact quality of life if

Tinea Corporis

Tinea corporis is a superficial dermatophyte infection of the glabrous (non-hairy) skin, excluding the scalp, groin, palms, and soles. Commonly known as ringworm of the body, this condition is characterized by annular, erythematous, and scaly plaques that typically expand outward. It is highly contagious and affects individuals of all age groups globally. Etiology: Understanding the

Tinea Capitis

Tinea capitis is a contagious dermatophytic fungal infection of the scalp and hair shafts, primarily affecting children but occasionally seen in adults. It is caused by various species of Trichophyton and Microsporum and spreads through direct human-to-human, animal-to-human, or fomite transmission. Clinically, it manifests in various forms ranging from non-inflammatory scaly patches to severe inflammatory

Tinea Barbae

Tinea barbae is a dermatophyte infection affecting the bearded regions of the face and neck. Predominantly seen in adult men, it is caused by a group of fungi known as dermatophytes, particularly species of Trichophyton and Microsporum. This condition often results from contact with infected animals or contaminated tools and surfaces. It presents in two

Tick-Borne Encephalitis Vaccination

Tick-borne encephalitis (TBE) is a potentially severe viral infection of the central nervous system transmitted primarily through the bite of infected ticks, particularly of the Ixodes ricinus and Ixodes persulcatus species. TBE is endemic in parts of Europe and Asia, with increasing incidence linked to changing climate patterns and rising outdoor recreational activities. The TBE

Thyrotoxicosis Crisis

Thyrotoxicosis crisis, also known as thyroid storm, is an acute, life-threatening condition characterized by an extreme surge in thyroid hormone activity. It represents the most severe form of thyrotoxicosis and requires immediate medical intervention. Often precipitated by stressors in patients with untreated or inadequately managed hyperthyroidism, this endocrine emergency can lead to multiorgan dysfunction and

Thyrotoxicosis

Thyrotoxicosis is a clinical state resulting from elevated levels of circulating thyroid hormones—thyroxine (T4) and triiodothyronine (T3)—regardless of their source. Unlike hyperthyroidism, which implies increased synthesis of thyroid hormones, thyrotoxicosis encompasses both endogenous overproduction and exogenous sources, including medication overuse and thyroiditis. Classification of Thyrotoxicosis by Etiology Thyrotoxicosis is classified based on the origin of
