ABSTRACT

En esta revisión de la literatura se describen aspectos epidemiológicos, fisiopatológicos, clínicos y terapéuticos sobre una presentación atípica y grave de escabiosis, la sarna costrosa o noruega. Esta presentación de escabiosis destaca por afectar principalmente a personas con condiciones de inmunodepresión o sociales que las hacen susceptibles de una alta carga parasitaria, además se asocia a un peor pronóstico y a riesgo de complicaciones. Desde el punto de vista terapéutico, sus estrategias difieren del manejo de la escabiosis clásica.(AU)


This literature review describes epidemiological, pathophysiological, clinical and therapeutic aspects of an atypical and severe presentation of scabies, Norwegian or crusty scabies. This presentation of scabies stands out because it mainly affects people with immunosuppressive or social conditions that make them susceptibleto a high parasite load, it is also associated with a worse prognosis and risk of complications. From a therapeutic point of view, their strategies differ from the management of classic scabies.(AU)

ABSTRACT

Abstract Scabies is an ectoparasitosis caused by Sarcoptes scabiei var. hominis, characterized clinically by pruritic lesions in typical locations; the crusted form is a rare manifestation. The diagnosis is usually established based on the clinical picture, but dermoscopy can be an important complementary method, as it allows the observation of a brownish triangular structure with a hang-glider appearance. A case of crusted scabies is reported; the magnification of the images obtained by digital dermoscopy allowed the demonstration of a structure usually observed only with videodermoscopy.

ABSTRACT

Crab-eating foxes (Cerdocyon thous) are wild canids found in practically all Brazilian states. They usually live and hunt in pairs, but can be found in small groups, which favors the transmission of diseases such as sarcoptic mange. This study aims to describe the epidemiological, parasitological and pathological findings of two fatal cases of sarcoptic mange in C. thous. Two wild canids were necropsied and cytological examination of skin and crust samples and histologic evaluation of various tissue samples were performed. Gross findings included poor body condition and extensive alopecia with thick skin crusts interspersed by intensely reddened alopecic areas. The cytological examination revealed numerous mites with short gnathosoma and rounded idiosoma that were transversally striated and presented triangular spines on the dorsal surface, terminal anus, and short and thick legs, characteristic of Sarcoptes scabiei. Histologic examination of the skin revealed numerous tunnels into and under the stratum corneum of the epidermis containing high amounts of S. scabiei. The mites were associated with marked acanthosis and hyperkeratosis, and mild superficial dermatitis. The findings reveal that sarcoptic mange is an important disease in wild canids.(AU)


Cachorros-do-mato (Cerdocyon thous) são canídeos selvagens encontrados em praticamente todos os estados brasileiros. Geralmente vivem e caçam em pares, mas podem ser encontrados em pequenos grupos, o que favorece a transmissão de doenças, como a sarna sarcóptica. O presente trabalho tem como objetivo descrever os achados epidemiológicos, parasitológicos e patológicos de dois casos fatais de sarna sarcóptica em cachorros-do-mato. Foram realizados necropsia de dois cachorros do mato, exame citológico de amostras de pele e crostas e exame histológico de amostras dos órgãos e tecidos. Na necropsia foram observados mau estado corporal, extensas áreas de alopecia, crostas cutâneas espessas que se desprendiam e eram intercaladas por áreas alopécicas intensamente eritematosas. No exame citológico foi observada grande quantidade de ácaros com gnatossoma curto e largo, idiossoma globoso, transversalmente estriado e com espinhos triangulares na superfície dorsal, ânus terminal e pernas curtas e grossas, característicos de Sarcoptes scabiei. Ao exame histológico da pele havia muitos túneis no estrato córneo da epiderme e abaixo dele, contendo grande quantidade de S. scabiei. Essas estruturas parasitárias estavam associadas a acantose e hiperqueratose acentuadas e dermatite superficial discreta. Os achados revelam a sarna sarcóptica como uma doença importante em cachorros do mato.(AU)

ABSTRACT

Scabies is a highly contagious skin infestation caused by the mite, Sarcoptes scabiei var. hominis. Complex responses to scabies mites in the innate, humoral, and cellular immune systems can cause skin inflammation and pruritus. Diagnosis can be challenging because scabies resembles other common skin conditions. We report the first Korean case of scabies in a hematopoietic cell transplant (HCT) recipient, initially suspected of skin graft versus host disease (GVHD). A T-cell acute lymphocytic leukemia patient underwent a sibling-matched allogeneic HCT and developed pruritus after cell engraftment. Treatment for GVHD did not improve the symptoms. He was diagnosed with scabies 30 days after the onset of symptoms.

ABSTRACT

In vitro bioassay using Sarcoptes scabiei as a test microorganism is a viable method of study for diverse drugs with acaricidal properties. A great amount of assays proves the diverse and efficient biological activity of extracts and compounds from Brazilian savanna plants. This study had as main object, test and compare the acaricidal activity of four Brazilian Cerrado bioproducts: Stryphnodendron adstringens Mart., Copaifera sp., Lafoensia pacari A. St Hil. and Pterodon emarginatus Vogel, 1837. To perform this test S. scabiei mites were collected from crusts removed on ears of highly infected sows. The mites were selected and separated in Petri dishes with three different concentrations (25, 50 and 75%) of each bioproduct, to evaluate their potential acaricidal activity. The mortality of the mites was counted in each Petri dish every hour, during five hours. The statistical analyses demonstrated differences between the bioproducts tested. The oleoresin of Copaifera sp. and P. emarginatus presented the best results with 100% of mites mortality after treatment. The ethanolic extracts of S. adstringens and L. pacari demonstrated lower acaricidal activity when compared to the oleoresins, with little or no difference among the control groups tested. This bioassay demonstrated to be efficient, reliable, low cost and easy accomplishment. Oil resins from Copaifera sp. and P. emarginatus have in vitro acaricidal activity against adult females of S. scabiei var. suis.(AU)


O uso de Sarcoptes scabiei como microrganismo teste para bioensaio in vitro é um método de estudo viável para diversas drogas acaricidas. Muitos ensaios comprovam a diversidade e eficiência de atividade biocida de extratos e componentes presentes em plantas do cerrado brasileiro. Este trabalho objetivou testar e comparar a atividade acaricida de quatro bioprodutos do cerrado brasileiro: Stryphnodendron adstringens Mart., Lafoensia pacari A. St Hil., Copaifera sp. e Pterodon emarginatus Vogel, 1837. Para este estudo, ácaros S. scabiei foram colhidos em crostas removidas de orelhas de fêmeas suínas altamente infestadas. Os ácaros foram selecionados, separados e colocados em placas de Petri com três diferentes concentrações (25, 50 e 75%) de bioprodutos, para avaliar o potencial de atividade acaricida de cada um. Foi realizada a contagem da mortalidade dos ácaros em cada placa de Petri a cada hora, durante cinco horas. As análises estatísticas demonstraram diferenças entre os bioprodutos testados. As óleo-resinas de Copaifera sp. e P. emarginatus apresentaram os melhores resultados, com 100% de mortalidade dos ácaros após tratamento. Os extratos etanólicos de S. adstringens Mart. e L. pacari demonstraram menor atividade acaricida quando comparados as óleo-resinas, com pequena ou nenhuma diferença entre os resultados dos grupos controle. Este ensaio demonstrou ser uma ferramenta eficiente, confiável, de baixo custo e de fácil realização. As óleo-resinas Copaifera sp. e P. emarginatus possuem atividade acaricida in vitro sobre fêmeas adultas de S. scabiei var. suis.(AU)

ABSTRACT

Abstract: We report an 80-year-old male patient with severe rheumatoid arthritis who was treated with tripterygium glycoside, an immunosuppressive agent made from the extract of a Chinese medicinal herb called Tripterygium wilfordii Hook F. The patient had no apparent skin lesions before the treatment, but he developed aggressive hyperkeratotic lesions with rapid progression after using tripterygium glycoside. He was repeatedly diagnosed with eczema, but treatment failed to achieve efficacy. Interestingly, a microscopic examination of the lesions revealed numerous scabies mites and eggs. Thus, we confirmed the diagnosis of Norwegian scabies infection. Treated with crotamiton 10% cream and 10% sulfur ointment for one month, the patient's clinical symptoms disappeared.

ABSTRACT

O objetivo deste trabalho foi avaliar a eficácia da ivermectina comprimido administrada por via oral no tratamento de Sarcoptes scabiei em cães naturalmente infestados. Foram selecionados 14 cães com raspados cutâneos positivos para o ácaro S. scabiei, idade de 1-5 anos, sem raça definida, distribuídos na mesma proporção de ambos os sexos, em dois grupos experimentais, compondo 7 animais por grupo. Todos os animais foram tratados a cada 7 dias, totalizando quatro tratamentos em cada cão (Dias 0,7,14 e 21). No grupo I foi administrada a ivermectina5 comprimido na dosagem de 0,2mg/kg e no grupo controle positivo (Grupo II) foi administrado um produto comercial a base de ivermectina comprimido na mesma dosagem do grupo I. Raspados cutâneos, avaliações clinicas e laboratoriais complementares dos cães foram realizadas durante o período de estudo. Clinicamente, não houve diferença significativa entre as avaliações antes e após o tratamento entre os dois grupos. Raspados negativos foram observados em ambos os grupos a partir do dia D+14, mantendo-se negativos até o final do período experimental. As lesões dermatológicas iniciais observadas no acompanhamento clínico regrediram e a partir do dia D+14 a melhora clínica era evidente em ambos os grupos. A ivermectina (Ivermectan Pet, UCBVET Saúde Animal) administrada por via oral foi eficaz no tratamento de S. scabiei em cães naturalmente infestados.(AU)


The aim of this study was to evaluate the efficacy of the ivermectin tablet administered orally for treatment of Sarcoptes scabiei in naturally infested dogs. Fourteen 1 to 5 year-old Mongrel dogs presenting positive skin scrapings for S. scabiei mites, distributed into two groups with equal proportions of both sexes, containing seven animals per group were used in this study. All dogs were treated every 7 days, totaling four treatments in each dog (days 0, +7, +14 and +21). Group I was administered the ivermectin5 tablet at a dose of 0.2mg/kg and positive control group II as given an ivermectin commercial product at the same dose of group I. Skin scrapings, clinical and laboratorial parameters analysis were performed during the experimental period. Clinically there were no significant differences between the two groups evaluated prior and after treatments. Negative skin scrapings were observed in both groups from day +14, remaining negative until the end of the experimental period. The initial skin lesions observed in clinical evaluation regressed from day +14, and clinical improvement was evident in both groups. The ivermectin tablet (Ivermectan Pet, UCBVET Saúde Animal) administered orally was effective to treat S. scabiei infection in naturally infested dogs.(AU)

ABSTRACT

La dermatoparasitosis producida por el acaro Sarcoptes scabiei variedad hominis, presenta una distribución poblacional relacionada al hacinamiento, condiciones higiénicas deficientes, pobreza y características geoclimáticas. El contagio ocurre de forma directa cutánea o a través de fómites. Liquiñe,poblado fronterizo de la Región de los Ríos, Chile, presenta en gran parte de su población las características mencionadas, con difícil acceso a comunicación digital y derivación médica. La incidencia de sarna se ve modificada al realizar intervenciones educacionales y saneamiento local, tanto como el diagnostico precoz y el tratamiento oportuno logran una modificación sustancial de la prevalencia. Se presenta el reporte de un caso. Paciente sexo femenino, 33 años, que presenta lesiones por grataje, excoriadas, con pápulo-pústulas de dos años de evolución, con manejo inicial sintomático por diagnóstico de dermatitis y psoriasis sin mejora de las lesiones. Conjuntamente se identifica en la hija de 4 años, lesiones primarias de características similares a las iniciales. Las lesiones de la menor se presentan como vesículas en espacio interdigital, muñe-cas, región periumbilical y surco acarino, compatibles con sarna. Se inicia tratamiento tópico permetrina 5 %a toda la familia, basados en las recomendaciones de la guía de manejo MINSAL. Se logra tras 2 años de evolución regresión total de los signos y síntomas a los 2 meses de iniciada la terapia. La presente revisión de caso pretende reforzar las ideas de diagnóstico precoz, tanto de caso índice como de probables contactos,educación continua a la comunidad. Tratamiento efectivo y oportuno, adecuado a la realidad socio cultural década localidad, tomando en cuenta factores de riesgos para la presentación y el abandono de la terapia. Asimismo promover las redes institucionales para la distribución de tratamiento, asesoramiento por especialistas y conocimientos actualizados de la semiología de cada cuadro dermatológico por el médico general.


The dermato parasitosis producedby the Sarcoptes scabiei mite hominis variety, has apopulation distribution related to over crowding, poor sanitation, poverty and geo-climatic characteristics.Transmission occurs directly through skin or fomites.In the border town of Liquiñe in the Region de los Rios,Chile, a substantial amount of the population is subject to the above characteristics, with difficult access to digital communication and medical referrals. The incidence of scabies is modified through educational interventions, and local sanitation, as well as early diag-nosis and timely treatment thus achieving a substantial change in prevalence. A case report is presented. Female patient, 33 years old presents with excoriated crusted lesions, with papules and pustules following two years of development, initial symptomatic management diagnosis of psoriasis and dermatitis,showed no improvement of the lesions. At the same time the 4 year old daughter of the patient presented with primary lesions similar to baseline characteristics.The child ́s lesions presented as vesicles in interdigital space, wrists, periumbilical region and mite grooves compatible with scabies. Permethrin 5% topical treatment was prescribed for the whole family, basedon the recommendations of the MINSAL guide management is initiated. At 2 months of treatment therapy on set, complete recovery was achieved following two years of evolution of signs and symptoms.This case review aims to reinforce the ideas of earlydiagnosis, in both probable index case and contact,and continuing education in the community. Effective and timely treatment, in conjunction with the socio-cultural reality of each community, taking into account risk factors, such as seeking medical treatment and abandoning therapy. Furthermore, it is also intended to promote institutional networks for treatment dissemination, counseling by specialists and updated information for each dermatological presentation for the general medicine physician.

ABSTRACT

La escabiosis es una ectoparasitosis pruriginosa producida por el ácaro Sarcoptes scabiei, variedad hominis, específica del ser humano. Si bien su distribución es universal, con frecuencia es subdiagnosticada por asociarla únicamente a hacinamiento y malos hábitos de higiene. Se transmite por contacto directo con una persona afectada o a través de fómites, por lo que es muy común el contagio de los convivientes. Presentamos un caso de escabiosis en una paciente anciana evaluada por prurito generalizado. (AU)


Scabies is a human specific pruritic ectoparasitosis produced by the mite Sarcoptes scabiei var. hominis. Although it has a worldwide distribution, it is often underdiagnosed because it is only associated with overcrowding and poor hygiene. It is transmitted by a direct contact with an affected person or through fomites. The transmission to cohabitants is very common. We present a case of scabies in an elderly patient with generalized pruritus. (AU)

ABSTRACT

Scabies is caused by a mite, Sarcoptes scabiei var hominis, an obligate human parasite that burrows downwards into the epidermis. Scabies may be transmitted from objects, but it is most often transmitted by direct skin-to-skin contact, with a higher risk from prolonged contact. Treatment must involve the entire household or community to prevent reinfection. In Korea, the incidence of scabies has decreased dramatically since the late 1980s, but recent outbreaks in nursing homes and hospitals have been raising public health concerns. Herein, we describe 5 cases of scabies that occurred in 3 generations of a family and were confirmed by dermoscopy-oriented skin scraping with microscopic examination.

ABSTRACT

This study compares the efficacy of skin impression with acetate tape and the deep skin scraping test to find D. canis and S. scabiei in dogs. During six months, 134 samples were collected by both techniques from 115 dogs treated at the dermatology service of the Veterinary Hospital of the Federal University of Santa Maria (HVU-UFSM). Of these patients, 27 had demodicosis and 12 had scabies. The impression with acetate tape test (ITT) was shown to be significantly superior to the deep skin scraping test (DSST) in finding D. canis and S. scabiei mites (p = 0.007). Based on our results we could conclude that acetate tape impression is a reliable method for diagnosing and monitoring therapy of dermatopathies caused by mites and can be used to replace the traditional deep skin scraping method. In addition, since it is less traumatic for the dog, this method shows more acceptance by the owner.


Este estudo compara a eficácia da impressão cutânea com fita de acetato ao raspado cutâneo profundo para a pesquisa de D. canis e S. scabiei. Em um período de seis meses, foram coletadas 134 amostras de cada uma das técnicas de um total de 115 cães atendidos na rotina dermatológica do Hospital Veterinário Universitário da Universidade Federal de Santa Maria (HVU-UFSM). Desses pacientes, 27 cães apresentavam sarna demodécica e 12 cães, escabiose. A impressão cutânea com fita de acetato, quando comparada ao raspado cutâneo profundo, demonstrou ser significativamente superior na pesquisa dos ácaros D. canis e S. scabiei (p = 0,007). Conclui-se que o método da fita de acetato pode ser usado em substituição ao raspado profundo de pele para o diagnóstico e controle da terapia das enfermidades dermatológicas produzidas por ácaros. Além de ser um método sensível, ele é menos traumático para o animal, sendo, dessa forma, mais aceito pelo proprietário.

ABSTRACT

Scabies caused by the genus Sarcoptes scabiei var canis is a prevalent infection in dogs and affects abandoned, malnourished and overcrowded animals, causing hair loss and an intensely pruritic crusting dermatitis. In humans the manifestation is a self-limiting pruritic dermatitis, but persistent cases are described. An outbreak of sarcoptic mange is reported in a family group (seven people, including a 5 month infant and his mother). The infective source was their own house dog who was taken from the street. The diagnosis was confirmed by the detection of mites and eggs in the acarotest of the dog and mites of S. scabei in the infant. Sarcoptic mange should be suspected in individuals with allergic dermatitis who have contact with dogs. Treatment in humans is usually symptomatic and may need miticides if the infection persists. The control of the disease requires an appropriate pet treatment.


La sarna producida por el género Sarcoptes scabiei var canis, infección prevalente en perros y de alto potencial zoonótico, afecta a animales abandonados, desnutridos y hacinados y causa alopecia y una dermatitis costrosa intensamente pruriginosa. En el ser humano produce una dermatitis pruriginosa generalmente autolimitada, pero se describen casos persistentes. Se reporta un brote de sarna sarcóptica en un grupo familiar (siete personas, incluidas una lactante y su madre) cuya fuente de infección fue su mascota canina recogida de la calle. El diagnóstico fue confirmado por visualización en el ácarotest de ácaros y huevos en el perro y ácaros de S. scabiei en la lactante. La sarna sarcóptica debe sospecharse en casos de dermatitis alérgica en personas con contacto con perros. El tratamiento en el humano, habitualmente sintomático, puede necesitar acaricidas si el cuadro persiste. El control de la enfermedad requiere el adecuado tratamiento de la mascota.

ABSTRACT

We report a rare case of bullous scabies with bullous pemphigoid in a 59-year-old male patient. He presented with a 9-month history of exhibiting multiple, variable-sized, red-to-brown, pruritic cutaneous patches, and papules with tense bullae on his whole body. A direct smear of the bullous lesions was performed and was negative for scabies mites. Histopathologic findings (hematoxylin and eosin staining) revealed Sarcoptes scabiei in the stratum corneum. There were sub-epidermal blisters with massive eosinophil and lymphocyte infiltration in the epidermis and upper dermis. Direct immunofluorescence microscopy showed linear deposition of IgG at the dermo-epidermal junction. Indirect immunofluorescence microscopy of samples acquired for the salt-split skin test showed linear IgG deposition in the epidermis. Skin lesions improved after the patient was treated with an anti-scabietic and steroids.

ABSTRACT

BACKGROUND: Scabies is an ectoparasite caused by the mite Sarcoptes scabiei var. hominis, an obligate human parasite. Although its incidence has been decreasing, it is not a rare dermatologic disease and is difficult to diagnosis. OBJECTIVE: To evaluate the clinical characteristics of scabies patients and find out etiologic factors in transmission. METHODS: Two hundred and ninety-five patients who were diagnosed with scabies at the Dermatologic Department, Myongji Hospital, Goyang city, Korea were enrolled. Medical records were evaluated in a retrospective manner. RESULTS: We studied 295 scabies patients who were diagnosed by the mineral oil test or skin biopsy. The mean age of the patients was 58.2 (male: 56.7/female: 61.2), and 74% of patients were over 60 years. There was seasonal variation in occurrence, and scabies was found to be most common in winter. The majority of suspected routes of infection were transmission through convalescent hospitals (38.1%) and caregivers (15.2%). Nosocomial infection and communal living were the major causes. 73.8% of scabies patients had underlying medical disease, such as hypertension (32.2%) and dementia (11.9%). CONCLUSION: Currently, scabies prevalence is still increasing in Goyang city, because of the increased number of convalescent hospitals.

ABSTRACT

Introducción: La escabiosis o sarna humana es una dermatosis causada a partir de la infección cutánea por Sarcoptes scabiei. Una variante severa y rara de ella es la escabiosis noruega o costrosa, que ha repuntado en los últimos años por el incremento en patologías que causan inmunosupresión. Clínicamente se presenta con hiperqueratosis y placas costrosas predominantemente en tórax, cabeza, palmas y plantas. Su diagnóstico es sencillo, mediante la observación microscópica del artrópodo. Se ha descrito su tratamiento con permetrina, benzoato de bencilo e ivermectina. Caso: Paciente masculino de 38 años de edad, con antecedente de sarna noruega tratada hace 2 años y hábito alcohólico acentuado. Inicia enfermedad actual hace 2 meses, caracterizada por pápulas pruriginosas generalizadas que aumentaron progresivamente en cantidad, formando placas costrosas. Examen físico: xerosis cutis, placas hiperqueratósicas de variadas formas y tamaños, algunas coalescentes, fácilmente desprendibles, sobre base eritematosa, brillante, rezumante, localizadas en cuello, tronco y extremidades. Examen microscópico: huevos y adultos de Sarcoptes scabiei. Tratamiento: cefazolina, maleato de clorfeniramina, cetirizina, ivermectina. Discusión: La sarna noruega recurrente en un paciente adulto sin patología de base conocida, debe conllevar a la búsqueda de causas que comprometan la respuesta inmune del individuo. Más allá de las patologías médicas y medicamentos con efectos inmunosupresores conocidos, debe también indagarse el consumo habitual sustancias como alcohol, agente con demostradas propiedades supresoras sobre la respuesta inmune innata y adquirida. En este caso, el tratamiento dermatológico debe ser complementado con el manejo adecuado del hábito alcohólico subyacente a la patología del paciente.


Background: Scabies is a dermatosis caused by infection due to Sarcoptes scabiei. An uncommon and severe form of this condition, Norwegian or crusted scabies, has shown an increasing incidence in recent years, due to the growing number of pathologies causing immunosupression. Clinical presentation includes hyperkeratosis and crusted plaques mainly on the skin of the thorax, head, palms and soles. It is easily diagnosed by direct observation of the arhtropode. Permethrin, benzyl benzoate and ivermectin have been described as effective therapeutic resources. Case: A 38-year-old male patient, with previous history of Norwegian scabies treated 2 years ago, and heavy consumption of alcohol is described. Presented illness begins 2 months ago, with the appearance of generalized pruriginous papules which progressively grew into crusted plaques. Physical examination: xerosis cutis, hyperkeratosic plaques in different shapes and sizes, some of them converging, easily removable, on an erytematous, bright, humid base, located on the skin of the neck, torso and limbs. Microscopic examination: eggs and adult forms of Sarcoptes scabiei. Treatment: cefazolin, clorpheniramine, cetirizin, ivermectin. Discussion: Recurrent Norwegian scabies in an adult patient without history of a previous disease, must be a reason to find other causes that jeopardize the individual’s immune response. Besides medical conditions and drugs known to have immunosuppressing effects, habits such as alcohol consumption must be interrogated, for it has been demonstrated that this substance has suppressing effects on innate and acquired immunity. The dermatologic treatment must be complimented with an accurate management of the alcohol abuse which underlies the disease.

ABSTRACT

Scabies is one of the most common world-wide arthropod-born diseases in both humans and animals caused by the "itch" mite Sarcoptes scabiei. The incidence of scabies has shown a tendency to increase for the last several years in Korea. The previous peak incidence in Korea was between the early 1970s and early 1980s. A substantial part of the cyclic resurgence of scabies has been considered the result of inexperience and indifference of medical doctors toward the disease. The recent resurgence is presumed to be derived from not only indifference of the doctors but also an increase in elderly patients admitted to nursing homes and eldercare hospitals. Scraping using mineral oil for scabies patients is a very simple and effective method for definite diagnosis. A new diagnostic method using a dermoscope is also effective, especially for very young patients. Lindane and crotamiton are two available antiscabietic preparations in Korea. Crotamiton is less effective, while infants and pregnant women should not use lindane. In conclusion, medical personnel should be alert coping with the resurgence of scabies, and it is strongly suggested that other antiscabietic drugs such as permethrin, ivermectin, etc. should be made available for resistant patients in the near future in the Republic of Korea.
