Influência da Disbiose na Patologia do Couro Cabeludo

In recent years, several studies have demonstrated the involvement of the intestinal microbiota in immune-mediated diseases such as diabetes, ulcerative colitis, and multiple sclerosis. There are few data on the follicular microbiome and its role in the pathogenesis of scalp diseases. Some studies show influence of dysbiosis on these diseases, and manipulation of the microbiome may represent a possible therapeu- tic option. This article reviews current knowledge regarding the impact of dysbiosis on dermatological diseases of the scalp, such as seborrheic dermatitis, psoriasis, alopecia areata, androgenetic alopecia, lichen planus pilaris, frontal fibrosing alopecia and decalvant folliculitis. A broader understanding of this may suggest additional treatments beyond conventional therapies.

Diagnostic Accuracy of Trichoscopy in Inflammatory Scalp Diseases: A Systematic Review

<b><i>Background:</i></b> The common inflammatory scalp diseases, such as psoriasis, seborrheic dermatitis, lichen planopilaris, discoid lupus erythematosus, contact dermatitis, or pemphigus may share similar clinical features. <b><i>Objective:</i></b> To identify and systematically review the available evidence on the accuracy of trichoscopy in inflammatory scalp disorders. <b><i>Methods:</i></b> A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 58 articles were included in the analysis. <b><i>Results:</i></b> The following trichoscopy features were found to show the highest specificity for the respective diseases: in psoriasis: diffuse scaling, simple and twisted red loops, red dots and globules, and glomerular vessels; in seborrheic dermatitis: atypical vessels, thin arborizing vessels, and structureless red areas; in discoid lupus erythematosus: follicular plugs and erythema encircling follicles; in lichen planopilaris: milky red areas or fibrotic patches; in contact dermatitis: twisted red loops; in pemphigus foliaceus: white polygonal structures and serpentine vessels; in pemphigus vulgaris: red dots with whitish halo and lace-like vessels; and in dermatomyositis: lake-like vascular structures. <b><i>Limitations:</i></b> Different nomenclature and variability in parameters, which were analyzed in different studies. <b><i>Conclusion:</i></b> This systemic analysis indicates that trichoscopy may be used with high accuracy in the differential diagnosis of inflammatory scalp diseases.

Head lice, dandruff and other scalp diseases are still one of the main problems of the students at the Nurul Qarnain boarding school. Factors that influence the development of disease are poor personal hygiene due to the students' lack of understanding of this disease. Anti-dandruff shampoo, is expensive and is insufficient to treat head lice problem among students. Furthermore, the absence of professional barbers in the boarding school environment is also one of the factors that triggered this problem. The results of this activity are increased knowledge of students about hair health from 58.8% to 98.24% and the ability and skills of students to make anti-dandruff shampoo and hair cutting. This is expected to increase awareness and ability to care for hair and provide added value to the economy.

Tinea Capitis and Tinea Corporis caused by Microsporum canis in an 82-year-old Woman: Efficacy of Sequence Analysis

Tinea capitis is more common in children than in adults. Due to the low incidence of this condition among adults, it is frequently misdiagnosed as other scalp diseases, such as seborrheic dermatitis, psoriasis, and cellulitis. Herein, we describe an 82-year-old woman who presented with erythematous scaly patches and alopecia. Mycological examinations revealed tinea capitis caused by Microsporum canis. The patient was then successfully treated with antifungal medications.

Hair disorders

This chapter discusses inflammatory scalp diseases and hair shedding (telogen effluvium and pattern hair loss). Inflammatory diseases of the scalp can affect all epidermal surfaces or focus upon the follicle, with relative sparing of the interfollicular skin. Eczema and psoriasis are examples of the former; other diseases, such as lichen planopilaris or discoid lupus erythematosus, are examples of the latter. Some follicular diseases, such as the family of diseases based on alopecia areata (alopecia areata (small areas of hair loss), alopecia totalis (whole scalp), and alopecia universalis (whole body)), cause barely visible follicular inflammation which results in hair loss but no scarring. Some patients present with hair shedding or change of hair pattern as their primary complaint, with no scalp disease; this is telogen effluvium. Others present with an altered pattern of scalp hair without conspicuous shedding; this is pattern hair loss.
