“…The use of dermoscopy to diagnose scabies can decrease the false-negative diagnosis rate when compared with skin scrapings. 5 A serologic test specific for S scabiei has been developed, with 100% sensitivity and 93.75% specificity, and may lead to more accurate diagnosis if widely used. 22 The most common treatment used was topical permethrin as a single agent (69%).…”

“…3 Examination findings include serpiginous white lines indicative of the mite burrowing; these classically occur in the interdigital web spaces, the areolae of female breasts, or the male genitalia, but they may be found on other body sites. Visualizing burrows or the mite on dermoscopy can assist in the diagnosis [5][6][7] (Figure 1). A "gold standard" diagnosis relies on the visualization of ova, feces, or the mites themselves using light microscopy 8,9 ( Figure 2).…”

Background: Scabies is a neglected skin disease, and little is known about current incidence and treatment patterns in the United States. The purpose of this study was to examine demographic data, treatment types, success of treatment, and misdiagnosis rate of scabies in an outpatient dermatology clinic.Methods: A retrospective chart review of patients diagnosed with scabies within the past 5 years was performed.Results: A total of 459 charts were identified, with 428 meeting inclusion criteria. Demographic data, diagnostic method, treatment choice, misdiagnosis rate, treatment failure, and itching after scabies are also reported. Children were the largest age group diagnosed with scabies, at 38%. Males (54%) were diagnosed with scabies more than females. The majority of diagnoses were made by visualizing ova, feces, or mites on light microscopy (58%). At the time of diagnosis, 45% of patients had been misdiagnosed by another provider. Topical permethrin was the most common treatment used (69%), followed by a combination of topical permethrin and oral ivermectin (23%), oral ivermectin (7%), and other treatments (1%).Conclusion: Our findings suggest that more accurate and faster diagnostic methods are needed to limit unnecessary treatment and expedite appropriate therapy for scabies.

“…The brown triangle corresponds to the pigmented anterior part of the mite (the head and the two anterior pairs of legs), while the posterior part which corresponds to the abdomen and legs appear translucent and is subsequently not observed by dermoscopy [46,47] . Interestingly, dermoscopy is known to be useful in the therapeutic follow-up of scabies as well [48] .…”

Abstract:Over the last few years, dermoscopy has been shown to be an effective diagnostic tool in assisting the noninvasive diagnosis not only of skin tumors but also of various general dermatological disorders. The use of dermoscopy has offered a new morphological dimension supporting the diagnosis and clinical follow-up of several dermatological conditions. Within the last years, dermoscopy is gaining ground in general dermatology as well. Among the large spectrum of skin infections, specific dermoscopic patterns have been described for common skin infections such as viral warts, molluscum contagiosum, scabies, and pediculosis, as well as for tinea nigra, tungiasis, and cutaneous larva migrans. Also, common skin disorders such as psoriasis, pityriasis rosea or lichen planus show characteristic dermoscopic patterns. The aim of this article is to provide an overview of the use of dermoscopy in general dermatology by analyzing the dermoscopic differential diagnosis of relatively common dermatological disorders grouped according to their clinical characteristics.

“…1,5 Sempre que possível o diagnóstico deve ser confirmado pela observação microscópica dos ácaros e/ou ovos obtidos a partir de um raspado cutâneo, ou pelo recurso à dermatoscopia. [29][30][31][32][33] A dermatoscopia tem-se assumido como uma ferramenta útil no diagnóstico da escabiose, pois é não-invasiva, pouco dispendiosa em tempo, bem aceite pelos doentes, e facilmente acessível aos dermatologistas. [30][31][32] Permite a visualização de um achado típico -o sinal de "asa-delta" ou "rasto de avião" (Fig.…”

RESUMO -Introdução:A escabiose é uma infestação cutânea parasitária comum nos cuidados de saúde primários, pediatria e dermatologia. Apesar de não ser ameaçadora da vida, tem elevada morbilidade e impacto na qualidade de vida. Nos países em desenvolvimento, a escabiose está associada a altas taxas de sobreinfeção cutânea bacteriana, nomeadamente de impetigo. Objetivos: Rever os aspetos gerais da escabiose, com particular enfâse no diagnóstico e tratamento. Analisar a realidade epidemiológica nacional e internacional e as opções terapêuticas disponíveis em Portugal. Material e métodos: Revisão narrativa da literatura científica, incluindo livros e bases de dados científicas (PubMed/Medline, Cochrane, UpToDate, IndexRMP). Discussão: A escabiose é uma dermatose com características clínicas muito típicas, nomeadamente, o prurido frequente, a aparência das lesões cutâneas e sua distribuição, e a presença de contexto epidemiológico. O tratamento eficaz do doente e dos contactos próximos é dependente de um reconhecimento atempado da doença, sendo fundamental evitar atrasos no diagnóstico, baixa adesão ao tratamento e sua aplicação incorreta. Conclusão: Atendendo à eficácia e toxicidade das várias opções terapêuticas, a permetrina a 5% e a ivermectina oral são consideradas de primeira linha. Contudo, em Portugal, pela ausência de comercialização destas, o mais usado é o benzoato de benzilo. A explicação cuidadosa e correta do tratamento ao doente tem um papel essencial para o seu sucesso. Em Portugal, seria útil e aconselhável haver uma notificação dos casos de escabiose. PALAVRAS-CHAVE -Benzoatos; Escabiose; Ivermectina; Permetrina; Portugal. Scabies: Review and Focus on the Portuguese Reality ABSTRACT -Introduction: Scabies is a parasitic cutaneous infection, which is common in primary care, pediatrics and dermatology. Although it isn't life threatening it causes considerable morbidity and has a substantial impact in the quality of life. In developing countries it is associated with high rates of cutaneous bacterial superinfection, namely impetigo. Objectives: To review the general aspects of scabies, with a particular emphasis on the diagnosis and treatment. To analyze the national and international epidemiological situation and the available treatment options, particularly in Portugal.Material and Methods: Narrative review of the scientific literature, including textbooks and scientific databases (PubMed/Medline, Cochrane, UpToDate, IndexRMP)
