ABSTRACT

Objetivo:identificar na literatura como os óleos essenciais são utilizados em onicomicose. Métodos: revisão integrativa com buscas realizadas nas bases de dados MEDLINE/PubMed, Web of Science, Cochrane, SCOPUS e BVS, sendo 13 estudos analisados. Resultados: o uso de óleos essenciais Melaleucaalternifólia, Lavandulaangustifólia, Eucalyptuscitriodora e Foeniculumvulgare mostram-se eficazes e trazem benefícios no tratamento da onicomicose, por inibirem o crescimento micelial dos fungos infectantes das unhas. Sendo assim, os profissionais de saúde envolvidos nos cuidados em pessoas com onicomicose devem se manter atualizados sobre tais alternativas de tratamento e consequentemente da melhora da assistência prestada a esses pacientes. Conclusão: a eficácia antifúngica de uma variedade de óleos foi comprovada com diferentes formas de apresentação e possíveis associações. Entretanto, o nível da evidência apresentado foi baixo, o que justifica a necessidade de estudos mais robustos sobre a temática.


Objective:identify in the literature how essential oils are used in onychomycosis. Methods:integrative review with searches performed in the MEDLINE/PubMed, Web of Science, Cochrane, SCOPUS and BVS databases, with 13 studies analyzed. Results: the use of essential oils Melaleuca alternifolia, Lavandula angustifolia, Eucalyptus citriodora and Foeniculum vulgare are effective and bring benefits in the treatment of onychomycosis, as they inhibit the mycelial growth of the nail fungus. Therefore, health professionals involved in the care of people with onychomycosis must keep themselves updated on such treatment alternatives and, consequently, on improving the care provided to these patients. Conclusion: the antifungal efficacy of a variety of oils has been proven with different forms of presentation and possible associations. However, the level of evidence presented was low, which justifies the need for more robust studies on the subject

ABSTRACT

Resumen: Una proporción importante de infecciones en el pie diabético consisten en onicomicosis y tinea pedis, problema común en el pie, amenazante de la viabilidad del tejido que puede provocar infecciones bacterianas secundarias. Requieren períodos prolongados de tratamiento antimicótico con alta tasas de recaídas y reinfección. Diversos estudios han mostrado la seguridad y eficacia de las nanopartículas de plata (NP Ag) como agente antimicrobiano. Realizamos un estudio donde se evaluó el tratamiento con NP Ag en dermatomicosis del pie de pacientes diabéticos. Método: estudio piloto, abierto, prospectivo, randomizado y controlado en pacientes que asisten a una policlínica de pie diabético. Dieciocho pacientes cumplieron con los criterios de inclusión conformándose dos grupos homogéneos. Ambos grupos recibieron tratamiento estándar que consistió en antimicótico tópico y desbastado mecánico. El grupo intervención utilizó un textil (medias) confeccionadas con hilos con NP Ag. Se realizó control clínico y microbiológico hasta las 12 semanas. Se evaluó el porcentaje de remisión y el tiempo hasta alcanzar el mismo. Resultados: predominó la onicomicosis y el germen Trichophyton rubrum. En el grupo intervención se logró un mayor porcentaje de remisión de lesiones y en un tiempo menor que el grupo control. Conclusiones: el uso de medias confeccionadas con hilos de NP Ag se asoció con una mayor probabilidad de curación completa en un período de 12 semanas a pesar de que el número de pacientes no permitió llegar al nivel de significación estadística, pudiendo contribuir a la prevención de infecciones o úlceras suplementarias en el pie diabético.


Summary: Onychomycosis and tinea pedis represent a significant proportion of infections in the diabetic foot, a common foot problem, and they constitute a threat to the viability of tissues that may provoke secondary bacterial infections. To combat them, antifungal treatments are required for long periods of time, the rates of relapse and reinfection being high. Several studies have proved the safety and effectiveness of silver nano particles (NP Ag) as an antimicrobial agent. A study was conducted to assess nanoparticle agents for foot dermatomycosis in diabetic patients. Method: pilot, open, prospective randomized and controlled study in patients who are assisted in a diabetic foot policlinic. 18 patients complied with the inclusion criteria and two homogeneous groups were formed. Both groups received standard treatment consisting in topic antifungal and mechanical roughing. The intervention groups used a textile (stockings) made with silver nanoparticle threads. Clinical and microbiological control was made during 12 weeks, also assessing the remission percentage and the time it took to achieve it. Resultados: onychomycosis and trichophyton rubrum prevailed. The intervention group showed a greater percentage of remission of lesions in a period of time that was shorter than that of the control group. Conclusions: the use of stockings made with NP Ag threads was associated with a greater probability of complete healing, in a 12-week period, despite the fact that the number of patients was not statistically significant. This could contribute to the prevention of supplementary infections or ulcers in the diabetic foot.


Resumo: Uma proporção significativa de infecções do pé diabético consiste em onicomicose e Tinea pedis, um problema comum nos pés que ameaça a viabilidade do tecido e pode causar infecções bacterianas secundárias. Requerem períodos prolongados de tratamento antifúngico com altas taxas de recidiva e reinfecção. Vários estudos têm demonstrado a segurança e a eficácia das nanopartículas de prata (NP Ag) como agente antimicrobiano. Realizamos um estudo onde o tratamento com NP Ag foi avaliado na dermatomicose do pé de pacientes diabéticos. Método: estudo piloto, aberto, prospectivo, randomizado e controlado em pacientes atendidos em uma policlínica de pé diabético. Dezoito pacientes preencheram os critérios de inclusão, formando dois grupos homogêneos. Ambos os grupos receberam tratamento padrão que consiste em antifúngico tópico e moagem mecânica. O grupo intervenção utilizou um tecido (meias) confeccionado com fios NP Ag. O controle clínico e microbiológico foi realizado até 12 semanas. A porcentagem de remissão e o tempo para alcançá-la foram avaliados. Resultados: predominaram a onicomicose e o germe Trichophyton rubrum. No grupo intervenção, obteve-se maior percentual de remissão das lesões e em menor tempo que o grupo controle. Conclusões: o uso de meias confeccionadas com fios NP Ag esteve associado a uma maior probabilidade de cura completa, no período de 12 semanas, apesar do número de pacientes não permitir atingir o nível de significância estatística, podendo contribuir para a prevenção de infecções ou úlceras adicionais no pé diabético.

ABSTRACT

Objective:To investigate dermoscopic manifestations and features of melanonychia.Methods:A retrospective analysis was carried out on dermoscopic images of 4 common types of melanonychia collected in Department of Dermatology, Xijing Hospital, the Fourth Military Medical University from January 2016 to July 2020.Results:A total of 266 cases of melanonychia were collected, including 64 (24.1%) of subungual melanoma, 52 (19.5%) of nail matrix nevi, 89 (33.5%) of subungual hemorrhage, and 61 (22.9%) of onychomycosis. Subungual melanoma and nail matrix nevi mostly occurred in the fingernails. To be specific, subungual melanoma most frequently occurred in the thumbnails (62.8%) , while nail matrix nevi mostly involved the 2 nd - 5 th fingernails (73.9%) . Subungual hemorrhage and onychomycosis mostly occurred in the toenails, and there were 51 (57.3%) cases of subungual hemorrhage of the toenails and 46 (75.4%) cases of onychomycosis of the toenails. Subungual melanoma mostly occurred in patients aged over 40 years (49 cases, 76.8%) , while the other 3 types of melanonychia mostly affected patients aged under 40 years. Dermoscopic manifestations of subungual melanoma mainly included regular longitudinal bands (35 cases, 54.7%) or irregular bands (25 cases, 39.0%) whose width was greater than 3 mm in 87.5% cases, Hutchinson sign (36 cases, 56.3%) , and ruptures (15 cases, 23.4%) which mainly were black-brown in color; dermoscopic manifestations of nail matrix nevi mainly were a single regular pigmented band (52 cases, 100%) whose width was less than 3 mm in 36 (69.2%) cases, and Hutchinson sign (26 cases, 50%) , while no ruptures were observed in nail matrix nevus lesions; subungual hemorrhage dermoscopically manifested as diffuse macules (74 cases, 83.1%) , and globular dark red or black hemorrhagic structures were observed in 85 (95.5%) cases; fungal melanonychia was dermoscopically characterized by irregular dark brown longitudinal bands (54 cases, 88.5%) . Conclusions:Subungual melanoma was dermoscopically characterized by regular longitudinal bands with a width of greater than 3 mm, nail matrix nevi by regular longitudinal bands, subungual hemorrhage by diffuse macules, and onychomycosis by irregular longitudinal bands. Dermatoscopy can be used to identify melanonychia lesions and provide a basis for auxiliary diagnosis of subungual melanoma.

ABSTRACT

Introducción: los hongos miceliales no dermatofitos (HMND) pueden causar un gran número de infecciones, entre ellas, la onicomicosis. Su implicancia como agentes patógenos y su significado clínico en esta afección, se encuentran sujetos al cumplimiento de los criterios de Walshe y Mary P. English. Presentamos un caso de onicomicosis causada por un hongo hifomiceto poco frecuente, del género Asper-gillus sección Candidi, en una paciente inmunocompetente y su estrategia terapéutica. Materiales y métodos: se estudió una paciente inmunocompetente, de 43 años de edad, con lesión en uña de primer dedo del pie derecho, de 10 años de evolución. Se realizó toma de muestra para examen micológico. Resultados: el examen directo reveló la presencia de hifas hialinas irregulares, ramificadas y tabica-das, compatibles con HMND. En muestras seriadas, desarrollaron colonias blanco algodonosas, cuya micromorfología fue concordante con Aspergillus sección Candidi. La identificación fue confirmada en la Unidad de Micología del Hospital de Infecciosas Francisco Javier Muñiz de la Ciudad Autónoma de Buenos Aires, Argentina. Allí también se realizaron pruebas de sensibilidad a antifúngicos, resultando sensible a itraconazol y terbinafina. Conclusión: exponemos un caso de onicomicosis causada por Aspergillus sección Candidi, HMND no queratinolítico, de escasa frecuencia de aparición, siendo el primer caso descripto y publicado en Argentina. También se planteó una estrategia terapéutica efectiva, que condujera a la cura clínica y microbiológica, de la uña de la paciente.


Introduction: non-dermatophyte mycelial fungi (HMND) can cause a large number of infections, including onychomycosis. Its implica-tion as pathogens and its clinical significance in this condition are subject to compliance with Walshe's and Mary P. English's criteria. We present a case of onychomycosis caused by hyphomycete rare fungus, of the genus Aspergillus section Candidi, in an immunocompetent patient and its therapeutic strategy. Materials and methods: a 43-year-old immunocompetent patient with a 10-year-old right-toe nail lesion was studied. Samples were taken for mycological examination. Results: the direct examination revealed the presence of irregu-lar, branched and tabulated hyaline hyphae, compatible with HMND. In serial samples, they developed white cotton colonies, whose micromorphology was consistent with Aspergillus, section Candidi. The identification was confirmed at the Mycology Unit of Francisco Javier Muñiz Infectious Hospital in the Autonomous City of Buenos Aires, Argentina. Susceptibility to antifungals was also tested there, resulting in susceptibility to itraconazole and terbinafine. Conclusion: we present a case of onychomycosis caused by Aspergillus section Candidi, non-keratinolytic HMND, of rare occurrence, being the first case described and published in Argentina. An effective therapeutic strategy was also proposed that led to the patient's toenail's clinical and microbiological cure.

ABSTRACT

O onicomatricoma é um tumor raro do complexo ungueal, de etiologia desconhecida. Apresenta-se com maior incidência em mulheres na 5ª década de vida. Contudo, é possível que esta ocorrência esteja equivocada devido a dados e informações que ainda não foram seguramente esclarecidos. O propósito do presente estudo é fazer uma revisão de literatura e relatar dois casos de onicomatricoma. Foram incluídos dois pacientes do sexo masculino, com faixa etária distinta e apresentações diferentes do tumor. O entendimento deste trabalho evidencia que a raridade e a incidência relatadas na literatura são questionáveis, e que o onicomatricoma pode ser subdiagnosticado


Onychomatricoma is a rare tumor of the nail complex of unknown etiology. It has a higher incidence in women in the 5th decade of life. However, this occurrence may be mistaken due to data and information that have not yet been fully elucidated. This study aims to review the literature and report two cases of onychomatricoma. We included two male patients with different age ranges and different tumor presentations. This study shows that the rarity and incidence reported in the literature are questionable and that the onychomatricoma can be underdiagnosed

ABSTRACT

Resumen: La onicomicosis (OM) es una infección fúngica de las uñas, cuyo principal agente causal es el Tricophytum rubrum. Si bien es una patología infrecuente en niños, se ha observado un aumento en la prevalencia en el último tiempo. Hasta la fecha, existen diversos estudios y guías clínicas de OM en adultos. Sin embargo, la literatura en edad pediátrica es escasa, lo que dificulta el tratamiento en pediatría. En el presente articulo se revisa la literatura actual, los métodos diagnosticos de OM, datos epidemiológicos locales y globales, y se presentan las opciones de tratamiento disponibles conside rando su eficacia y perfil de seguridad en población pediátrica.


Abstract: Onychomycosis (OM) is a fungal infection of the nails, whose main etiologic agent is Trichophytum rubrum. Although, it is an unusual pathology in children, in the last years an increase in its preva lence has been observed. To date, there are several studies and clinical guidelines for OM in adults. However, literature in children is scarce, which makes pediatric treatment difficult. The objective of this publication was to review the current literature in order to establish diagnostic methods for OM, national and international epidemiological data, and to provide treatment options taking into account their efficiency and safety profile in the pediatric population.

ABSTRACT

Background: Onychomycosis is one of the most common fungal nail infections caused by Dermatophytes, Non-Dermatophytic Molds (NDM) and Yeast. Though it is not life-threatening, can cause pain, discomfort, and disfigurement. It decreases the nail growth rate. Objectives: This study was carried out to document the clinico-mycological pattern and antifungal susceptibility pattern of onychomycosis.Methods: The study group included 130 consecutive patients with suspected fungal nail infections, attending Dermatology outpatient department of King George Hospital, Visakhapatnam, Andhra Pradesh during November 2012 to August 2014. The nail clippings of the patients were collected and subjected to KOH mounts for direct microscopy and fungal culture and antifungal susceptibility tests.Results: Onychomycosis was common among males (66.92%) than females (33.08%) with highest incidence was in age group 31-40 years (41.37%). Finger or toenails were exclusively involved in 32.18% and 55.18% patients respectively while these were involved concurrently in the rest of the 12.65% patients. Distal and lateral subungual onychomycosis seen in 64.36% of the patients was the most common clinical type. KOH and culture positivity were recorded in 56.92% and 48.46% cases respectively. Dermatophytes (50.58%) were predominant isolate followed by NDM (27.58%) and yeast (21.84%). Clotrimazole and ketoconazole were most effective antifungals against dermatophytes. For NDM, itraconazole, nystatin and amphotericin B and for yeast fluconazole and itraconazole were effective.Conclusions: The present study gives an insight about the aetiological agents causing onychomycosis and their anti-fungal susceptibility pattern in this region. Thus, it can help in taking adequate control measures to prevent it.

ABSTRACT

Introduction: Onychomycosis is a fungal infection of thetoenails or fingernails that may involve any component of thenail unit, including the matrix, bed, or plate. Onychomycosisis caused by dermatophyte fungi, non dermatophyte mouldsand yeasts. Prevalence rates for OM varying from 3 to 5%have been found in most studies; however, a few reportssuggest a higher prevalence of even up to 26% in the generalpopulation. Hence through this study an attempt was made toidentify the various clinical patterns of onychomycosis and toidentify pattern of drug resistance in onychomycosis.Material and methods: The proposed study was carriedout in Outpatient Department of Dermatology Venereologyand Leprosy, Rohilkhand Medical College and Hospital,Bareilly, a tertiary care hospital in western Uttar Pradeshfor one year (November 2017- October 2018) on patientshowing nail changes suggestive of onychomycosis, usingdirect microscopy using potassium hydroxide. The culturemedium SDA with chloramphenicol was used. Sensitivity toTerbinafine, Fluconazole, Itraconazole and Griseofulvine wasstudied.Result: The most common pattern of onychomycosis seenwas distal lateral subungual onychomycosis. Pattern of drugresistance is maximum with Griseofulvin (49%) and least withTerbinafine (20%).Conclusion: A total of 104 patients were enrolled, withmean age 35.93 years. Males were more commonly involvedcompared to females. The culture results were positive among55 patients and negative in 49 patients. The most commoncausative agent isolated was dermatophyte moulds followedby non-dermatophytes and yeasts.

ABSTRACT

Introducción: la onicomicosis es la infección del aparato ungueal causada por hongos dermatofitos, no dermatofitos o levaduras. Constituye una enfermedad frecuente en la práctica médica, con impacto considerable en lo emocional, social, laboral y económico. Objetivo: describir las características epidemiológicas de la onicomicosis en pacientes que consultaron en un servicio dermatológico. Materiales y Métodos: estudio observacional retrospectivo de corte transverso, donde se analizaron fichas epidemiológicas de pacientes que acudieron al servicio de Dermatología del Hospital Nacional de Itauguá y el Centro de Especialidades Dermatológicas en el periodo comprendido entre julio del 2016 a agosto del 2019. Resultados: se analizaron 464 pacientes con onicomicosis. El cultivo fue positivo en el 83 % (385/464) de los casos. Se observó preferentemente en mujeres 72 % (276/385), franja etaria entre los 31 y 65 años 70,1 % (270/385), de procedencia urbana 76 % (292/385) y actividad quehaceres domésticos 41 % (157/385). El 23 % (87/385) presentó una o más comorbilidades asociadas a la aparición de onicomicosis, siendo la diabetes en el 70 % (61/385) de éstas. La localización fue en uñas de pies en 58,2 % (259/ 400), uña de manos en 31,2 % (141/400) y en el 10,1 % (45/400) de los casos se observó onicomicosis en ambas localizaciones. Los géneros aislados con mayor frecuencia fueron Trichophyton y Candida, y las especies fueron T. rubrum y Candida parapsilosis. En las onicomicosis de uñas de los pies se aislaron dermatofitos en un 63,7 % (165/259), mientras que en uñas de las manos se aislaron Candida spp. en el 77,3 % (107/141). Conclusión: la onicomicosis produce una afectación que se observa mayoritariamente en pacientes adultos, generalmente mujeres que se dedican a los quehaceres domésticos, procedentes de áreas urbanas, con afectación principal de las uñas de los pies, siendo los agentes causales más frecuentes, T. rubrum y C. parapsilosis.


Introduction: onychomycosis is an infection of nails caused by dermatophyte fungi, not dermatophytes or yeasts. It constitutes a frequent disease in medical practice, with considerable emotional, social, labor and economic impact. Objective: to describe the epidemiological characteristics of onychomycosis in patients who attended in a dermatological service. Materials and Methods: a retrospective cross-sectional observational study, where epidemiological records of patients who attended the Dermatology service of the Itauguá National Hospital and the Dermatological Specialties Center in the period from july 2016 to august 2019 were analyzed. Results: 464 patients with onychomycosis were analyzed. The culture was positive in 83 % (385/464) of the cases. It was mainly observed in women 72 % (276/385), age group was between 31 and 65 years 70.1 % (270/385), of urban areas 76 % (292/385) their activities were house as and household chores activity 41 % (157 / 385). 23 % (87/385) presented one or more comorbidities associated with onychomycosis, with diabetes in 70 % (61/385) of these. The location was in toenails in 58.2 % (259/400), fingernail in 31.2 % (141/400) and in 10.1 % (45/400) of the cases onychomycosis were observed in Both locations. The most frequently isolated genera were Trichophyton and Candida, and the species were T. rubrum and Candida parapsilosis. In the onychomycosis of the toenails, dermatophytes were isolated in 63.7 % (165/259), while in the fingernails, Candida spp. in 77.3 % (107/141). Conclusion: onychomycosis produces an affectation that is mostly adult patients, usually women who are engaged in household activities, from urban areas, the main involvement were toenails, being the most frequent agent isolated were, T. rubrum and C. parapsilosis.

ABSTRACT

Introducción: Para el correcto diagnóstico de la onicomicosis es fundamental realizar una adecuada toma de muestra. Objetivo: Evaluar la competencia de los alumnos del grado en Podología en la realización de la toma de muestra ungueal como experiencia preclínica y clínica. Métodos: Estudio observacional, descriptivo y transversal, realizado sobre una muestra de 75 alumnos, pertenecientes a segundo (n = 45) y cuarto curso (n = 30) del grado en Podología. Los alumnos de segundo curso no contaron con experiencia previa, mientras que los de cuarto ya habían realizado prácticas preclínicas y clínicas. Se evaluó el procedimiento de toma de muestras ungueales mediante el grado de seguimiento de cada alumno del protocolo preestablecido y explicado. Además, se obtuvo el porcentaje de cultivos contaminados tras el período de incubación de las muestras. Resultados: Los alumnos de cuarto curso siguieron más fielmente el protocolo de toma de muestras ungueales y las contaminaron significativamente menos que los alumnos de segundo curso (23,3 por ciento frente al 51,1 por ciento; p-valor = 0,017). La experiencia previa en toma de muestras ungueales (p-valor = 0,027) y en la realización de quiropodias (p-valor = 0,016) redujo significativamente el porcentaje de cultivos contaminados. Conclusiones: Una sola práctica preclínica no es suficiente para que la mayoría de los alumnos de segundo curso adquieran la competencia de toma de muestra. Las experiencias preclínica y clínica de los alumnos de cuarto curso constituyen un factor determinante para la correcta realización de la toma de muestra ungueal(AU)


Introduction: For the correct diagnosis of onychomycosis, it is essential to take an adequate sample. Objective: To assess the competence of students of the degree in Podiatry in the realization of nail sampling as a preclinical and clinical experience. Methods: Observational, descriptive and cross-sectional study carried out on a sample of 75 students, belonging to the second (n=45) and fourth academic years (n=30) of the degree in Podiatry. The second-year students did not have previous experience, while the fourth-year students had already done preclinical and clinical practices. The nail sampling procedure was assessed by the degree of follow-up of each student of the pre-established and explained protocol. In addition, the percentage of contaminated cultures was obtained after the incubation period of the samples. Results: The fourth-year students followed the nail sampling protocol more faithfully and contaminated them significantly less than second-year students (23.3 percent versus 51.1 percent; p value=0.017). Previous experience in nail sampling (p value=0.027) and in performing podiatry (p value=0.016) significantly reduced the percentage of contaminated cultures. Conclusions: A single preclinical practice is not enough for most second-year students to acquire the competence of sampling. The preclinical and clinical experiences of fourth-year students constitute a determining factor for the correct realization of the nail sampling(AU)

ABSTRACT

RESUMEN Introducción: las infecciones fúngicas en piel, cabello y uñas son comunes a nivel mundial, en este marco, la onicomicosis constituye la enfermedad más prevalente de la que la provincia no es ajena. Objetivo: describir factores de riesgo, características y dermatosis asociadas en pacientes mayores de 18 años con onicomicosis en un área de salud. Métodos: estudio observacional, descriptivo y transversal en la consulta de Dermatología del Policlínico Universitario "Raúl Sánchez Rodríguez", en el período 2017-2018. Resultados: predominó el sexo femenino (55,1 %) y el grupo de edades entre 40 y 59 años (43,8 %), el factor de riesgo predominante fue el empleo de calzado oclusivo (84,9 %). Predominó la localización en pies (unilateral) (45,9 %), la forma clínica lateral + superficial distal (33 %), así como de la onicolisis + incurvación (54,6 %) como principal alteración ungueal. La principal modificación ungueal fueron las líneas longitudinales (70,8 %), en cuanto a la consistencia un engrosamiento de las uñas (68,1 %), siendo la leuconiquia (47 %) y melnoniquia (36,8 %) las principales coloraciones detectadas. La tiña pedis (55 %) y la crural (10,8 %) fueron las dermatosis asociadas más frecuentes. Conclusiones: es importante el conocimiento del comportamiento clínico epidemiológico de las onicomicosis para de esta manera poder actuar y modificar los factores de riesgo e incidir sobre las dermatosis asociadas y de alguna manera disminuir la incidencia de onicomicosis.


ABSTRACT Introduction: fungal infections in skin, hair and nails are common worldwide, in this context, onychomycosis is the most prevalent disease where the province is no exception. Objective: to describe the risk factors, characteristics and associated dermatosis in patients older than 18 years old with onychomycosis in a health area. Methods: observational, descriptive and cross-sectional study conducted at Raúl Sánchez Rodríguez University Polyclinic, Dermatology Clinic during the period 2017-2018. Results: female sex predominated (55,1 %) and the age group between 40 and 59 years (43,8 %), the predominant risk factor was the use of occlusive footwear (84,9 %). Localization in feet (unilateral) (45,9 %), lateral plus distal superficial clinical type (33 %), as well as onycholysis plus incurvation (54,6 %) predominated as the main ungueal alteration. The main ungueal modification belonged to the longitudinal lines (70,8 %), in terms of consistency a thickening of the nails (68,1 %), with leukonychia (47 %) and melanonychia (36,8 %), which were the main colors detected. Tinea pedis (55 %) and crural (10,8 %) were the most frequent associated dermatosis. Conclusions: it is important to distinguish the clinical epidemiological behavior of onychomycosis in order to be able to act and modify the risk factors and influence of the associated dermatosis and in one way or another to reduce the incidence of onychomycosis.

ABSTRACT

Abstract: Background: Of all nail disorders seen in dermatology offices, half of them are due to onychomycosis. The main differential diagnosis is nail psoriasis. The objective of this study was to compare the microscopic findings, other than the presence of fungi, in the clipping of onychomycosis versus normal nails and nail psoriasis. Methods: Cross-sectional study of onychomycosis cases, analyzed by clipping and compared with data on normal nails and those with nail psoriasis. Results: Sixty-two onychomycosis samples were compared with 30 normal nails and 50 nails with psoriasis. In onychomycosis, measurement of subungual region, serous lakes, neutrophils and number of layers of parakeratosis are more intense than in psoriasis. Onychocariosis is less common in psoriasis, while bacteria are more frequent. The nail transition zone is more commonly blurred and irregular in onychomycosis. Conclusion: Clipping helps in the differential diagnosis of onychomycosis and nail psoriasis and may be useful even when fungi are not found.

ABSTRACT

Introduction: Nail disorders comprise about 10% of alldermatological conditions. They may get involved invarious systemic diseases, infectious processes, nutritionaldeficiencies, ageing, genetic disorders, and neoplasms.Current study objective was to see the clinical pattern of nailchanges in patients presenting with various nail disorders andto determine the clinical pattern of nail involvement in variousdermatoses.Material and methods: This was a cross sectional study inwhich patients presenting to our department with any naildisorders were examined. A proper history, examination andthe relevant investigations like KOH, nail culture, and nailbiopsy were also done.Results: A total of 500 patients were screened, 282 femalesand 218 males. The most common nail change observed waslongitudinal ridging (45.6%), followed by distal subungualhyperkeratosis (35.8%) and cuticular changes (35.2%).Onychomycosis was the most common nail disorder observed,constituting 36.2% of all nails diseases. Among non infectivediseases, nail psoriasis was the most common nail disorderfollowed by nail lichen planus.Conclusion: A variety of nail changes can occur in variousdermatological and various other systemic disorders. So athorough clinical examination of nails is of prime importanceto correlate all these nail changes and to make dermatologiststo reach a conclusive diagnosis.

ABSTRACT

Introduction: One of the documented leading cause ofblindness in India is cataract as many patients with cataract donot have access to hospitals and surgery and to avoid blindnessdue to cataract, the only remedy is to perform hospital basedcataract surgery on a large scale. There is an increase in anumber of cataract patients due to improved quality of life,health indices and increased life expectancy. Study aimedto see the visual outcome and complications among patientsundergone manual SICS with PC-IOL implantation.Material and Methods: The present prospectiveobservational study was conducted on 72 patients who wereselected in various screening eye camps to undergo cataractextraction surgery by manual small incision cataract surgerytechnique with posterior chamber IOL implantation (MSICSwith PC-IOL).Results: Total of 72 eyes of patients who underwent manualsmall incision cataract surgery were studied. Best correctedpreoperative visual acuity of ≥ 6/60 was found in 13 patientswhile postoperatively on day1 total of 60 patients had visualacuity of ≥ 6/60. The final 6th week postoperative bestcorrected visual acuity of 6/12-6/9 was found in 65 patients.Iris prolapse was seen in 3 patients followed by posteriorcapsule rent which was seen in 2 patients. Mild postoperativeuveitis was seen in 20 followed by striate keratopathy in 8patients while hyphaema was seen in 2 patients.Conclusion: MSICS is a safe and effective procedure, due toits low rates of intraoperative and postoperative complicationswhich are easily treatable. Visual acuity is only one measureof the functional success of cataract surgery and the goodpostoperative visual outcomes achieved by our patientsfurther adds on to its benefits as a good surgical technique.MSICS can be performed as procedure of choice for largevolume cataract surgeries

ABSTRACT

Resumen Objetivo: Describir las características clínico-epidemiológicas de una población con diagnóstico de infección cutánea micótica en los pies confirmada por examen directo con KOH y cultivo en un centro de referencia de Bogotá, Colombia. Material y método: Estudio observacional descriptivo en el que se incluyeron todos los pacientes con lesiones en los pies que fueron atendidos en el servicio de micología entre el año 2011 y el 2016. Se analizaron las características sociodemográficas, clínicas, etiologías y el perfil de tratamiento por medio de un análisis bivariado. Resultados: Se incluyeron 305 pacientes, de los cuales el 82% residía en zona urbana de la ciudad de Bogotá. El hábito más frecuente fue bañarse descalzo, la forma clínica que predominó fue la interdigital y el 35% de los casos presentó de forma simultánea tiña del pie y onicomicosis. Los agentes etiológicos más comunes fueron los dermatofitos con el 95,2% de los casos. Discusión: La presentación clínica sugestiva de micosis, además del resultado positivo del examen directo y del cultivo, permiten hacer el diagnóstico de estas in fecciones. Las características sociodemográficas de quienes sufren este tipo de micosis en Colombia se relacionan con su contagiosidad y tendencia a la cronicidad. La intervención de tales aspectos debe hacer parte de las estrategias para su prevención.


Summary Objective: To describe the clinical and epidemiological characteristics of the population with cutaneous mycosis in the feet confirmed by positive mycological studies diagnosed in a reference center in Bogota, Colombia. Methods: Descriptive observational study in which all patients with lesions in the feet that were treated in the mycology service between 2011 and 2016 were included. In all cases KOH examination and fungal culture were performed. The sociodemographic and clinical characteristics, etiologies and the treatment profile were assessed using a bivariate analysis. Results: A total of 305 patients were included, of which 61% were men and 82% lived in an urban area of the city of Bogota. The most common behavior was to take a barefoot bath, the most important comorbidities were venous insufficiency and psoriasis, the main clinical form was interdigital and 35% of the cases presented simultaneously tinea pedis and onychomycosis. The group of dermatophytes was the most frequently isolated (95.2%). Discussion: Clinical examination corresponding with mycosis in the feet, direct examination, and positive culture, allow the physician accurate diagnosis and guide the most appropriate treatment of these infections according to their etiology. The sociodemographic characteristics of those who suffer from this mycosis in Co lombia are related to their contagiousness and tendency to chronicity, therefore, the intervention of such aspects must be part of the strategies for their prevention.

ABSTRACT

Onychomycosis is a fungal nail infection caused by various fungal species, including dermatophytes, non-dermatophytes, and yeast. It is one of most bothersome nail problems, because it may cause permanent deformity of the nail, local pain, paresthesia, and difficulties performing activities of daily living and engaging in social interactions. Additionally, the treatment of onychomycosis is considered to be challenging because of the long duration of treatment, high recurrence and treatment failure rates, and drug interactions. In this article, we review the prognostic factors for onychomycosis treatment, the treatment options that have been approved, and off-label therapies and devices. Furthermore, we describe preventive therapy for recurrence and emerging methods to achieve a high cure rate. For successful treatment of onychomycosis, the risk factors should be clarified according to the patient's status and the clinical characteristics of onychomycosis. Recently, combinations of various treatment options, such as systemic therapy with simultaneous topical antifungal agents and boost therapy, have been reported as effective treatments of onychomycosis. In addition, laser therapy, photodynamic therapy, and plasma therapy have been proposed as emerging curative options. Providing patient-specific treatment based on an understanding of these treatments plays a pivotal role in achieving better treatment results. This article suggested the updated treatment options for onychomycosis to help clinicians make proper plans and achieve better results.

ABSTRACT

BACKGROUND: Onychomycosis is a chronic fungal nail disease that may have a profound effect on quality of life (QOL). OBJECTIVE: The purpose of this study was to evaluate the QOL in patients with toenail onychomycosis using the onychomycosis quality of life questionnaire (ONYCHO) and to determine the factors influencing the QOL of toenail onychomycosis patients. METHODS: A total of 102 adults (mean age, 59.54 years) with toenail onychomycosis who visited our department between July 2017 and June 2018 completed the ONYCHO, which consists of statements pertaining to social, emotional, and symptom problems. All patients with toenail onychomycosis had been diagnosed by positive direct microscopic examination. RESULTS: Most of the patients demonstrated significantly reduced QOL. The degree of QOL impairment differed between subgroups. Both social (p<0.01) and emotional (p<0.05) impairments were more conspicuous in the female than in the male patients, although there were no differences according to symptoms. Patients with more extent of toenail involvement were more affected by onychomycosis in all three ONYCHO scales (p for trend<0.05). In terms of the type of toenail onychomycosis, the degrees of social (p for trend<0.05), emotional (p for trend<0.05), and symptom (p for trend<0.01) impairment were more prominent in patients with total dystrophic onychomycosis than in those with superficial white onychomycosis and distal and lateral subungual onychomycosis. A tendency toward better QOL in terms of social problems, but not emotional or symptom problems, was associated with a longer duration of the disease (B, 8.95, 95%CI, 0.99–16.91). CONCLUSION: Although toenail onychomycosis is not a life-threatening disease, it has a significantly negative impact on the overall QOL of patients, which should be a focus of concern.
