Eritema multiforme, una rara presentación de exantema en población pediátrica: a propósito de un caso / Erythema multiforme, a rare occurrence of exanthema in the pediatric population: on the subject of a case

El Eritema multiforme (EM) o eritema polimorfo es una enfermedad aguda de la piel de naturaleza inmunológica con o sin compromiso de mucosas, que puede comportarse como crónica recurrente. Se presenta con lesiones cutáneas en diana distintivas, a menudo acompañado de úlceras o bullas en mucosas (oral, genital u ocular). Entre sus formas clínicas se distingue: una forma menor caracterizado por un síndrome cutáneo leve y su forma mayor que se manifiesta como una afectación cutánea con daño mucoso marcado. Entre sus principales diagnósticos diferenciales se encuentran el Síndrome de Stevens-Johnson (SSJ) y Síndrome de Lyell (Necrólisis epidérmica tóxica (NET)). Tiene una incidencia estimada < 1%, siendo su forma mayor levemente más frecuente que su forma menor (0.8-6 por millón/año). Puede darse a cualquier edad, presentando un peak de incidencia entre los 20 y 30 años, predominando ligeramente el sexo masculino con una proporción 3:2, sin predilección racial. Su presentación en edad pediátrica es rara, más aún en la primera infancia. En esta población es más frecuente el EM menor recurrente. En el presente texto se reporta un caso de EM en población pediátrica como una rara forma de presentación exantemática, abordado en el Servicio de Pediatría del Complejo Asistencial Dr Victor Rios Ruiz (CAVRR)en la ciudad de Los Ángeles, Chile en el presente año.

Erythema multiforme (EM) also known as polymorph erythema is an acute skin disease of immunological nature with or without mucous membrane involvement, which may behave as chronic recurrent. It presents with distinctive targets like skin lesions, often together with ulcers or bullae in mucous membranes (oral, genital or ocular). Among its clinical forms are: a minor form characterized by a mild skin syndrome and its major form that manifests as a skin disease with marked mucosal damage. Among its main differential diagnoses are Stevens-Johnson Syndrome (SJS) and Lyell Syndrome (Toxic Epidermal Necrolysis (TEC)). It has an estimated incidence < 1%, with its major form being slightly more frequent than its minor form (0. 8-6 per million/year). It can occur at any age, presenting a peak incidence at the age between 20 and 30 years, with a slight predominance of males with a 3:2 ratio, without racial predilection. Its presentation in pediatric age is rare, even more so in early childhood. Minor recurrent EM is more common in this population. This paper reports a case of EM in the pediatric population as a rare form of exanthematic presentation, addressed at the Department of Pediatrics of the Complejo Asistencial Victor Rios Ruiz (CAVRR) in the city of Los Angeles, Chile this year.

Introducción. En el embarazo, las dermatosis afectan a menos del 20 % de las gestantes y representan un grupo heterogéneo de afecciones cutáneas, con una forma variada de presentación y evolución. El objetivo es presentar un caso de erupción polimorfa de inicio durante el puerperio, con una breve revisión de la literatura en torno a la patología y su tratamiento. Reporte de caso. Se presenta el caso de una paciente de 38 años en puerperio de su primera gestación, quien debutó con un cuadro clínico de erupción cutánea y prurito que inició en la zona abdominal y se extendió hacia los miembros inferiores. Las lesiones estaban constituidas por pápulas eritematosas que confluían hasta formar placas. Se diagnosticó con erupción polimorfa del embarazo y se dio manejo con antihistamínicos logrando la resolución de la patología. Discusión. La erupción polimórfica del embarazo es un trastorno inflamatorio benigno de la piel. Inicia con la aparición de pápulas pruriginosas que confluyen hasta formar placas eritematosas, que aparecen primero en el abdomen con excepción de la zona umbilical y parten, generalmente, de las estrías y se diseminan a las extremidades. El tratamiento consiste en la utilización de emolientes y antihistamínicos para el control de las lesiones y el prurito. Conclusiones. Aunque se trata de una patología benigna y autolimitada, es importante llegar al diagnóstico correcto e iniciar un manejo médico adecuado ya que síntomas como el prurito pueden generar lesiones por rascado que suelen infectarse y comprometer el estado de salud de las pacientes.

Introduction. During pregnancy, at least 20% of the expectant mothers are affected by several forms of dermatosis, which involve a heterogeneous group of skin conditions with a variety of manifestations and evolution. The objective is to present a case of initial polymorphic eruption during the postpartum period with a brief review of the literature related to the pathology and its treatment. Case report. We present the case of a 38 year-old postpartum patient in her first pregnancy, who exhibited a clinical case of skin eruption and pruritus that started in the abdominal area and extended to the lower limbs. The lesions consisted of erythematous papules that clustered together to form plaques. She was diagnosed with polymorphic eruption of pregnancy and was treated with antihistamines, which resolved the pathology. Discussion. Polymorphic eruption of pregnancy is a benign inflammatory disorder of the skin It starts with the appearance of pruritic papules that cluster together to form erythematous plaques that initially appear in the abdomen (with the exception of the umbilical area) and generally start at the stretch marks and disseminate to the extremities. Treatment consists of the use of emollients and antihistamines to control the lesions and the pruritus. Conclusions. Although this is a benign, self-limiting condition, it is important to reach a correct diagnosis and initiate adequate medical treatment, as symptoms like pruritus can generate lesions from scratching that usually become infected and compromiso the patients' health.

Fever with rash in a child in India.

Fever with rash is common among children and are seen by both dermatologists and pediatricians. Most of them are benign viral exanthems without much clinical significance. This article gives an overview of the infectious and noninfectious causes of fever with rash in children and how to diagnose them, with special emphasis on the Indian scenario as well. It also differentiates them from fever with rash caused by drugs. This review emphasizes that although benign in many cases, it is necessary to identify the signs of serious illnesses to prevent mortality or sequelae.

Diagnosis of human herpesvirus 6B primary infection by polymerase chain reaction in young children with exanthematic disease / Diagnóstico de infecção primária pelo herpesvírus humano tipo 6B através da técnica de reação em cadeia da polimerase em crianças com doença exantemática

INTRODUCTION: Exanthem subitum is a classical rash disease of early childhood caused by human herpesvirus 6B (HHV-6B). However, the rash is frequently misdiagnosed as that of either measles or rubella. METHODS: In this study, a nested multiplex polymerase chain reaction (PCR) was used to diagnose HHV-6B primary infection, differentiate it from infections caused by HHV-6A and compare it to antibody avidity tests. The samples were separated into case group and control group according to the results of the indirect immunofluorescence assay (IFA) technique. RESULTS: From the saliva samples analyzed, HHV-6A DNA was detected in 3.2 percent of the case group and in 2.6 percent of the control group. Regarding HHV-6B, PCR detected viral DNA in 4.8 percent of the case group and in 1.3 percent of the control group. Among the serum samples studied, a frequency of 1.7 percent was determined for HHV-6A in the case group and 1.2 percent in the control group. PCR did not detect HHV-6B DNA in serum samples. The sensitivity and specificity of the PCR technique ranged from 0 percent to 4.8 percent and 97.5 percent to 100 percent, respectively, compared to IFA. CONCLUSIONS: The PCR technique was not suitable for diagnosing primary infection by HHV-6B in children with exanthematic disease and should not substitute the IFA.

INTRODUÇÃO: O exantema súbito é uma doença comum durante a infância e pode ser causada pela infecção por herpesvirus humano tipo 6B (HHV-6B). No entanto, a erupção cutânea característica dessa doença, é frequentemente confundida com outras viroses como sarampo ou rubéola. MÉTODOS: Foi utilizada a técnica de reação em cadeia da polimerase (PCR) no formato nested multiplex para o diagnóstico de infecção primária por HHV-6B, diferenciação entre as infecções causadas pelo HHV-6A e comparação com testes de avidez de anticorpos. As amostras foram separadas em grupo caso e grupo controle, de acordo com os resultados do teste de imunofluorescência indireta (IFA). RESULTADOS: Nas amostras de saliva analisadas, o DNA do HHV-6A foi detectado em 3,2 por cento no grupo caso e em 2,6 por cento das amostras do grupo controle. Em relação ao HHV-6B, o DNA viral foi observado em 4,8 por cento no grupo caso e em 1,3 por cento no grupo controle. Após a realização da PCR nas amostras de soro, o DNA do HHV-6A foi detectado em 1,7 por cento no grupo caso e em 1,2 por cento no grupo controle, enquanto o DNA do HHV-6B não foi detectado. A sensibilidade e a especificidade da técnica de PCR variaram de 0 por cento a 4,8 por cento e de 97,5 por cento a 100 por cento, respectivamente, quando comparado com a IFA. CONCLUSÕES: A técnica de PCR não se mostrou adequada para o diagnóstico de infecção primária pelo HHV-6B em crianças com doença exantemática e não deve substituir a IFA.

Características clínico-epidemiológicas da doença Lyme-símile em crianças / Epidemiological characteristics of Lyme-like disease in children

OBJETIVO: Determinar a prevalência, distribuição etária, sazonalidade, características clínicas da doença Lyme-símile em menores de 15 anos. MÉTODOS: De julho/1998 a dezembro/2000 foi conduzido um estudo transversal em 333 pacientes, com exantema e febre. Foram coletadas amostras pareadas de sangue para a identificação de patógenos. Somente em 193 amostras, negativas aos outros patógenos (Parvovirus B19, Herpesvírus 6 humano, Sarampo, Rubéola, Dengue, Escarlatina e Enterovírus), foram realizadas a pesquisa da borreliose pelos métodos de Enzyme-Linked Immunosorbent Assay e Western-blotting. Outras variáveis clínicas, socioeconômicas, demográficas e climáticas foram estudadas. RESULTADOS: A prevalência da doença foi de 6,2 por cento(12/193). Das variáveis estudadas, houve predomínio em <6anos(83,2 por cento); sexo feminino (66,7 por cento); procedência da cidade de Franco da Rocha (58,3 por cento); com sazonalidade no outono-verão. O intervalo de atendimento foi de quatro dias. Sinais e sintomas com significância estatística: prurido, ausência da fissura labial e bom estado clínico. Outros dados presentes foram: irritabilidade (80 por cento); febre (?38ºC) (58,3 por cento) com duração de um a três dias. O exantema foi do tipo máculo-papular (33,3 por cento), urticariforme (25 por cento) e escarlatiniforme (16,7 por cento); predominando em tronco (60 por cento). Não houve apresentação clínica característica para diagnóstico da doença de Lyme-símile nestes pacientes. A sensibilidade e especificidade para o diagnóstico clínico contraposta com o diagnóstico laboratorial foi zero. O acompanhamento de 10 casos durante dois anos não evidenciou complicações cardiológicas ou neurológicas. Este é o primeiro estudo desta doença em crianças brasileiras. CONCLUSÃO: A prevalência da doença Lyme-símile foi baixa, não tendo sido lembrada no diagnóstico inicial dos exantemas, mas seu conhecimento é necessário, necessitando maior atenção médica.

BACKGROUND: To determine the prevalence, age distribution, seasonality and clinical characteristics of Lyme-simile disease in Brazilians less than 15 years of age. METHODS. From July, 1998 to November, 2000, a cross-sectional study was conducted in 333 patients with skin rash and fever. Paired blood samples were collected for identification of the pathogens. Only 193 samples which were negative for other pathogens (Parvovirus B19 Human, Herpesvirus 6 Human, Measles, Rubella, Dengue, Scarlet fever and Enterovirus), were tested for borreliosis by Enzyme-Linked Immunosorbent Assay and Western-blotting. Other clinical, socioeconomic, demographic and climatic variables were studied. RESULTS: Prevalence of the disease was 6.2 percent(12/193). Of the variables studied, there was predominance in: <6 years old (83.2 percent); females (66.7 percent); being from the city of Franco da Rocha (58.3 percent); and a summer/fall seasonality. The duration of care was 4 days. Signs and symptoms with statistical significance were itching; absence of lip notch and ocular pain; irritability and good clinical condition. Other clinical data presented were: pruritus (90 percent), irritability (80 percent) and fever (?38ºC) (58.3 percent) with a duration of 1 to 3 days. Erythema was maculo-papular (40 percent), urticaria-like (25 percent) and scarlatiniform (16.7 percent), occurring predominately on the trunk (60 percent). There were no primary clinical evidences of Lyme-simile disease in the patients under study. The sensitivity and specificity of the clinical diagnosis as opposed to the laboratory diagnosis was zero. There was no initial clinical suspicion of the disease in the 10 cases studied and followed up for two years that showed no evidence of cardiologic or neurological complications. This is the first study of Lyme-simile in Brazilian children. CONCLUSION: Prevalence of Lyme-simile disease was low, and it was not remembered at the initial diagnosis ...

Exantemas de la infancia / Childhood exanthems

En los últimos años han surgido algunos avances en el entendimiento de ciertos exantemas virales clásicos de la infancia, así como se ha relacionado algunos virus conocidos con exantemas atípicos y se han descrito nuevos exantemas probablemente vira les. Estos cuadros clínicos son parte de la consulta diaria y por ello requieren una revisión frecuente de los mismos.

Recent studies have introduced some progress in understanding of certain classic viral exanthems durig infancy: some well known viruses have been related with atypical exanthems, new exanthems, probably related with virus, have been described. These clinical pictures are quite common in daily practice and need to be frequently reviewed.

A case of baboon synrome due to mercury smoke of an amulet / 대한피부과학회지

Baboon syndrome is used to denote a systemic allergic contact dermititis with a characteristic color and distribution pattern. It is also referred to as mercury exanthem, because inhalation of mercury vapor usually causes the skiri lesion in a sensitized person. Diffuse pi,ikish erythema of the buttock, upper inner thigh, and axilla are characteristic features. We report a case of baboon syndrome developed after exposure to the smoke of a burning amulete a charm written on a piece of paper in a 12 year-old female. Mercury sensitivity was confirrned by a patch test. Atomic absorption by a spectrographic method and Scanning electron microscopy/energy dispersive for analysis X-ray detected mercury in the urine and the ed scraped pigments from the amulet, respectively.

Two Cases of Mercury Exanthem / 대한피부과학회지

We herein report two cases of systemic contact dermatitis probably due to inhalation of mercury. The first case is a 13 year-old boy who developed generalized erythema and dyspnea following the use of a coin-bleaching solution of unknown ingredient in his room. And the second case is a 10 year-old boy who developed generalized scarlatiniform eruptions on his trunk and flexural aspect of his extremities after hreaking a clinical thermometer. The typical clinical feature, the inverted triangular shaped erythema on flexural aspect of inner thigh, were appeared in both patients. On patch testing, they showed positive reactions to mercury and other mercury compounds.
