Ann Med Surg (Lond) 2024; 86:121-126. [PMID: 38222710 PMCID: PMC10783287 DOI: 10.1097/ms9.0000000000001530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 11/11/2023] [Indexed: 01/16/2024] Open
Abstract
Background Tinea capitis is a fungal infection that affects the scalp. It is caused by a group of fungi known as dermatophytes, which thrive in warm and moist environments. In Somalia, there is a data shortage regarding dermatological conditions, especially in Mogadishu, the most populous city in the country. Tinea capitis has gone unreported despite its high prevalence in Somali dermatology clinics and the Somali diaspora in Western countries. The absence of up-to-date information hampers the capability to diagnose, treat, and prevent Tinea capitis. Therefore, the study aims to evaluate dermoscopic signs about isolated organisms and potassium hydroxide (KOH) examination. Method A hospital-based cross-sectional study was implemented between January and April 2023 in Mogadishu, Somalia. All eligible Tinea capitis-infected children were included in the study. Microscopically, analysis was conducted by adding 10% of KOH in fungal elements. Data were analyzed using descriptive statistics and the χ2 test at P value less than 0.05. Results A total of 76 tinea capitis-infected children participated in the study; 56% were age group between 5-9 years old, 68.4% were male, and 92.1% showed KOH positivity. Trichophyton violaceum (65.8%) and Trichophyton sudanense (14.5%) were the most common fungal organisms detected in the culture. comma hairs (93.10%), scales (40.80%), and corkscrews (32.90%) were the most common dermoscopic signs of tinea capitis. The demographical characteristics and dermoscopic signs of tinea capitis significantly associated with the positivity of KOH examination were age, sex, comma hairs, corkscrew hairs, broken hair, Scales, and Zigzag hair. Conclusion Children in Mogadishu, Somalia, bear a significant burden of Tinea Capitis infections. Trichophyton violaceum and Trichophyton sudanense were the predominant causative agents identified in the cultures. The most common dermoscopic signs of tinea capitis observed in this study were comma hairs, scales, and corkscrew patterns. Hence, early diagnosis of Tinea Capitis infections and timely, effective treatments with contact tracing are highly needed.

Abstract
Tinea capitis is a widespread fungal infection that is even more common in rural areas of the world predominantly among children. The diagnosis of the infection and the identification of the responsible dermatophyte are determined by potassium hydroxide mount microscopy, Wood's lamp examination and mycological culture of the skin scrapings and hair samples. Nevertheless, this conventional setting has several limitations such as lack of availability, low sensitivity and specifity, and particularly prolonged turnaround time for fungal culture. Trichoscopy is a well-proven practical and beneficial aid to faciliate the diagnosis of scalp and hair disorders. Studies performed during the last 15 years revealed several characteristic trichoscopic findings of non-inflammatory tinea capitis namely comma hairs, corkscrew hairs, Morse code-like hairs and zigzag hairs. Thereby, trichoscopy has proved itself in the establishment of prompt diagnosis of TC, identification of the responsible fungus enabling to appropiate treatment on time, and evaluating treatment response by screening the clearance of the trichoscopic features.

Abstract
Tinea gladiatorum (TG) is a fungal skin infection that occurs among wrestlers and other contact sport athletes with a varied prevalence rate. The most common causative factor responsible as well for local outbreaks of the infection is an anthropophilic dermatophyte species—Trichophyton tonsurans (T. tonsurans). The purpose of this study was to gather current data about TG, including epidemiology, possible diagnosing methods, clinical features, treatment approaches, and potential prevention techniques. We also performed a systematic review of studies describing TG incidence. The prevalence of the disease varied from 2.4% up to 100%. That wide range of variability forces medical practitioners to update knowledge about TG and points to the fact that it still may be a diagnostic and therapeutic challenge. Spreading awareness among athletes and trainers is one of the most important preventive steps.

Abstract
OBJECTIVE Pediatric patients often reveal localized alopecic foci on the scalp. The essential point upon approaching a child with localized alopecia is distinguishing the two most common causes, alopecia areata and tinea capitis, as their treatments are entirely different. Although potassium hydroxide examination is the preferred method for their clear distinction, dermatoscopy is also emerging as a rapid diagnostic tool. This study aimed to assess and compare the dermatoscopic findings of alopecia areata and tinea capitis. MATERIALS AND METHODS Enrolled in this study were 34 children with tinea capitis and 21 children with alopecia areata admitting to a single-center outpatient clinic between 2017-2021. The authors confirmed all children's diagnoses by an integrative evaluation of clinical features, potassium hydroxide examination results, and treatment response patterns. Clinical features and the variables of interest (dermatoscopic findings) were investigated through the medical records and the baseline dermatoscopic images. RESULTS The most common dermatoscopic finding within the tinea capitis cohort was comma hairs, detected in 33 (97.1%) of the patients. Other findings of the tinea capitis group included squamation (n=31, 91.2%), broken and dystrophic hairs (n=30, 88.2%), corkscrew hairs (n=24, 70.6%), zigzag hairs (n=18, 52.9%), and pigtail hairs (n=9, 26.5%). The most common dermatoscopic finding within the alopecia areata cohort was exclamation mark hairs (n=13, 61.9%), that was followed by black dots (n=9, 42.9%), yellow dots (n=8, 38.1%), vellus hairs (n=6, 28.6%), and broken and dystrophic hairs (n=5, 23.8%). CONCLUSION Among the detailed evaluation of dermatoscopic findings of tinea capitis and alopecia areata patients, the only overlapping feature was dystrophic and broken hairs that could be present in both diseases; but were more common within the TC group than within the AA group (88.2% vs. 23.8%).

Abstract
Several types of cutaneous fungal infections can affect the population worldwide, such as dermatophytosis, cutaneous candidiasis, onychomycosis, and sporotrichosis. However, oral treatments have pronounced adverse effects, making the topical route an alternative to avoid this disadvantage. On the other hand, currently available pharmaceutical forms designed for topical application, such as gels and creams, do not demonstrate effective retention of biomolecules in the upper layers of the skin. An interesting approach to optimise biomolecules' activity in the skin is the use of nanosystems for drug delivery, especially solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC), which in the past decade has shown advantages like increased adhesiveness, great occlusive properties and higher biomolecule deposition in stratum corneum when designed for topical application. Considering the demand for more effective therapeutic alternatives and the promising characteristics of SLN and NLC for topical application, the present study sought to gather studies that investigated the potential of using SLN and NLC for the treatment of cutaneous fungal infections. Studies demonstrated that these nanosystems showed optimisation, mostly, of the effectiveness of biomolecules besides other biopharmaceutical properties, in addition to offering potential occlusion and hydration of the applied region.

Abstract
BACKGROUND Tinea capitis is the most common pediatric dermatophyte infection. Optimal treatment regimen differs according to the type of the dermatophyte involved. OBJECTIVES The aim of this work was to study the trichoscopic signs in relation to isolated organism in a sample of Egyptian patients with tinea capitis and the possibility of using them as a guide for selection of appropriate antifungal. METHODS This study was carried out on 60 subjects with tinea capitis. Patients were mycologically examined, both direct microscopy with KOH preparation and culture of the scraped hair materials on Sabouraud dextrose agar. Culture mounts were used for identification of the organism. Trichoscopic examination of all patients was performed using the Dermlite DLIII dermoscope. RESULTS There was significant higher prevalence of both comma and corkscrew hair in endothrix infection and T. violaceum-infected cases. On the other hand, there was significant higher prevalence of zigzag, barcode hairs, and white sheaths in ectothrix infection and M. canis-infected cases. CONCLUSION While some trichoscopic findings are nonspecific, others were found to be more specific. Finding zigzag hairs and barcode hairs points to ectothrix infection (M. canis), and it is recommended to start treatment with griseofulvin. On the other hand, finding comma hairs and corkscrew hairs without zigzag hairs and barcode hairs points to endothrix infection (T. violaceum), and it is recommended to start treatment with terbinafine in the usual dose.

Abstract
INTRODUCTION An increased incidence of tinea capitis has been observed over the last few decades. Trichoscopy is a non-invasive, in-office method helpful in establishing the correct diagnosis in patients with hair loss and inflammatory hair disorders. The objective was to review and analyze current data on the trichoscopy of tinea capitis. METHODS A systematic review of the literature was conducted using the PubMed, EBSCO and Scopus databases. The search terms included 'tinea capitis' combined with 'trichoscopy', 'dermatoscopy', 'dermoscopy', 'videodermatoscopy' or 'videodermoscopy'. RESULTS Of 326 articles, 37 were considered eligible for the quantitative analysis. The most characteristic (with a high predictive value) trichoscopic findings of tinea capitis included comma hairs (51%), corkscrew hairs (32%), Morse code-like hairs (22%), zigzag hairs (21%), bent hairs (27%), block hairs (10%) and i-hairs (10%). Other common, but not characteristic, trichoscopic features were broken hairs (57%), black dots (34%), perifollicular scaling (59%) and diffuse scaling (89%). Morse code-like hairs, zigzag hairs, bent hairs and diffuse scaling were only observed in Microsporum tinea capitis (8/29, 28%; 6/29, 21%; 4/29, 14% and 4/29, 14%, respectively). In Trichophyton tinea capitis, corkscrew hairs were more commonly detected compared to Microsporum tinea capitis (21/38, 55% vs 3/29, 10%). CONCLUSION The presence of characteristic trichoscopic features of tinea capitis is sufficient to establish the initial diagnosis and introduce treatment before culture results are available. Trichoscopy may be useful in distinguishing between Microsporum and Trichophyton tinea capitis.

Abstract
INTRODUCTION Tinea capitis is a scalp infection caused by different fungi. Etiological diagnosis is based on suggestive clinical findings and confirmation depends on the fungus growth in culture. However, it is not always possible to perform this test due to lack of availability. The association of clinical and dermatoscopic findings in suspected cases of tinea capitis may help the identification of the etiological agent, facilitating precocious, specific treatment. MATERIALS AND METHOD We report a prospective descriptive analytical study of 34 children with tinea capitis. We performed a trichoscopic examination of all patients; only six children were able to have the mycological culture. RESULTS Trichoscopy was abnormal in all 34 patients; it showed hair shaft abnormalities and, in some cases, scalp disorders too. We found that the comma and corkscrew appearance was found in microsporic tinea capitis, V-shaped hair was mainly seen in inflammatory tinea capitis, scales and follicular keratosis in non-inflammatory tinea capitis, and crusts and follicular pustules in inflammatory tinea capitis. Finally, erythema was seen in trichophytic and inflammatory tinea capitis. CONCLUSION We propose a classification of trichoscopic signs of tinea capitis. This classification will enable rapid diagnosis and prediction of the type of fungus before mycological culture, thus a faster and more adapted management. Our study shows the importance of trichoscopy in the diagnosis and monitoring of tinea capitis. We suggest further prospective studies with a larger number of patients with tinea capitis, having performed mycological culture, to confirm this classification.

Abstract
Dermoscopy is a noninvasive diagnostic tool that is currently being used for neoplastic skin lesions, several inflammatory and infectious diseases, and skin appendage disorders. As the clinical applications of dermoscopy beyond pigmented lesions are constantly increasing, the aim of this article is to provide an update on this topic. This comprehensive review substantiates how several diseases may show peculiar dermoscopy features so as to enhance the diagnosis and avoid (in selected cases) unnecessary histologic confirmation. In other cases, dermoscopy features may be shared with other conditions, with the advantage of narrowing down the differential diagnosis by ruling out those dermatoses with similar clinical aspect but different dermoscopic presentation.

Abstract
Over the last few years, dermoscopy has been shown to be a useful tool in assisting the noninvasive diagnosis of various general dermatological disorders. In this article, we sought to provide an up-to-date practical overview on the use of dermoscopy in general dermatology by analysing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical presentation, i.e. dermatoses presenting with erythematous-desquamative patches/plaques (plaque psoriasis, eczematous dermatitis, pityriasis rosea, mycosis fungoides and subacute cutaneous lupus erythematosus), papulosquamous/papulokeratotic dermatoses (lichen planus, pityriasis rosea, papulosquamous sarcoidosis, guttate psoriasis, pityriasis lichenoides chronica, classical pityriasis rubra pilaris, porokeratosis, lymphomatoid papulosis, papulosquamous chronic GVHD, parakeratosis variegata, Grover disease, Darier disease and BRAF-inhibitor-induced acantholytic dyskeratosis), facial inflammatory skin diseases (rosacea, seborrheic dermatitis, discoid lupus erythematosus, sarcoidosis, cutaneous leishmaniasis, lupus vulgaris, granuloma faciale and demodicidosis), acquired keratodermas (chronic hand eczema, palmar psoriasis, keratoderma due to mycosis fungoides, keratoderma resulting from pityriasis rubra pilaris, tinea manuum, palmar lichen planus and aquagenic palmar keratoderma), sclero-atrophic dermatoses (necrobiosis lipoidica, morphea and cutaneous lichen sclerosus), hypopigmented macular diseases (extragenital guttate lichen sclerosus, achromic pityriasis versicolor, guttate vitiligo, idiopathic guttate hypomelanosis, progressive macular hypomelanosis and postinflammatory hypopigmentations), hyperpigmented maculopapular diseases (pityriasis versicolor, lichen planus pigmentosus, Gougerot-Carteaud syndrome, Dowling-Degos disease, erythema ab igne, macular amyloidosis, lichen amyloidosus, friction melanosis, terra firma-forme dermatosis, urticaria pigmentosa and telangiectasia macularis eruptiva perstans), itchy papulonodular dermatoses (hypertrophic lichen planus, prurigo nodularis, nodular scabies and acquired perforating dermatosis), erythrodermas (due to psoriasis, atopic dermatitis, mycosis fungoides, pityriasis rubra pilaris and scabies), noninfectious balanitis (Zoon's plasma cell balanitis, psoriatic balanitis, seborrheic dermatitis and non-specific balanitis) and erythroplasia of Queyrat, inflammatory cicatricial alopecias (scalp discoid lupus erythematosus, lichen planopilaris, frontal fibrosing alopecia and folliculitis decalvans), nonscarring alopecias (alopecia areata, trichotillomania, androgenetic alopecia and telogen effluvium) and scaling disorders of the scalp (tinea capitis, scalp psoriasis, seborrheic dermatitis and pityriasis amiantacea).

Abstract
Tinea capitis remains a common childhood infection in many parts of the world. Yet knowledge of the underlying pathogenetic mechanisms and the development of effective immunity have shown striking advances, and new methods of diagnosis ranging from dermoscopy to molecular laboratory tests have been developed even though they have not been assimilated into routine practice in many centres. Treatment is effective although it needs to be given for at least 1 month. What is missing, however, is a systematic approach to control through case ascertainment and therapy.
