Hand, Foot and Mouth Disease and Care: A Short Case Report

ABSTRACT Hand, foot, and mouth disease (HFMD) is an acute viral infection occurring mostly in infants and children. Enterovirus 71 (EV71) infection mostly occurs in children < 5 years of age. Severe cases, however, are usually encountered in children under the age of 3 years, and exceedingly rare in teenagers > 14 years and adults. In this report, we present the case of an 11-year-old boy presenting with a hand, foot and mouth disease typical of HFMD.

Genotipificación del virus de la enfermedad mano-pie-boca atípica en un hospital pediátrico de la Ciudad de Buenos Aires, Argentina / Atypical hand-foot-mouth disease virus genotyping in a pediatric hospital in Buenos Aires city, Argentin

La enfermedad mano-pie-boca (EMPB) típica es exantemática, con sintomatología clásica de fiebre, exantema papulovesicular en las manos y los pies, asociada o no a herpangina. Es causada, principalmente, por enterovirus 71 y virus Coxsackie A16, miembros del género Enterovirus. En los últimos años, se han descrito brotes mundiales de EMPB con manifestaciones atípicas causadas, sobre todo, por el virus Coxsackie A6. La EMPB atípica se considera emergente con características clínicas y epidemiológicas peculiares: la afección de adultos, el predominio en invierno y un amplio espectro de manifestaciones clínicas en la extensión y la distribución de las lesiones. Las características morfológicas de las lesiones son muy variables: pueden simular varicela, impétigo o vasculitis.Se describe el caso de un niño de 4 años con EMPB atípica. Se detalla su forma de presentación, evolución clínica, metodología diagnóstica y terapéutica empleada.

Typical hand-foot-mouth disease (HFMD) is an exanthematous viral disease with a classic symptomatology of fever, papulovesicular rash on the hands and feet with or without herpangina. It is usually caused by enterovirus 71 and Coxsackievirus A16, members of the genus Enterovirus. Recently, worldwide outbreaks of HFMD with atypical manifestations caused by Coxsackievirus A6 have been described. Atypical HFMD is considered an emerging disease due to its peculiar clinical and epidemiological characteristics: it affects adults, has a wide spectrum of clinical manifestations in the extension and distribution of the lesions and occurs in winter. The morphological characteristics of the lesions are very variable and can be misdiagnosed as chickenpox, impetigo or vasculitis. Here we describe the symptoms, clinical evolution, diagnostic methodology and treatment employed on a 4-year-old male patient with atypical HFMD.

Reporte de caso de enfermedad mano-pie-boca con lesiones mucocutáneas que evolucionan a necrosis / A case report of hand, foot, and mouth disease with necrotizing mucocutaneous lesions

La enfermedad de mano-pie-boca es una patología originada en la mayoría de los casos por el virus coxsackie A tipo 16, aunque también puede ser ocasionada por otras cepas de la familia de los coxsackievirus. Dicho virus se propaga principalmente por vía fecal oral y, en menor proporción, por secreciones. Se presenta principalmente en verano, siendo frecuente en niños menores de 10 años. Dentro de dicha enfermedad las lesiones mucocutáneas que evolucionen en necrosis son poco frecuentes, constituyéndose en una complicación severa que requiere hospitalización. En el presente artículo se reporta un caso con diagnóstico de enfermedad mano-pie-boca, que evolucionó hacia lesiones mucocutáneas necróticas, mostrando una respuesta favorable a una terapia de soporte de aciclovir, líquidos y electrolitos.

In most cases, the cause of hand, foot, and mouth disease (HFMD) is coxsackievirus A type 16. The infection can also be caused by other strains of coxsackievirus, spreading mainly by the oral-fecal route, while it is less likely to be transmitted through secretions. HFMD occurs mainly in summer and is more common in children under ten. Skin lesions develop during the disease but rarely become necrotic. When present, they are a severe complication requiring hospitalization. This paper reports the case of a patient with HFMD who developed necrotic mucocutaneous lesions that responded favorably to intravenous acyclovir, fluids, and electrolyte support therapy.

Eccema coxsackium en adulto: presentación de un caso / Eczema coxsackium in adults: a case report

La enfermedad de pie, mano boca es una patología frecuente de observar en niños menores de 5 años, generalmente producida por virus Coxsackies y Enterovirus. Existen presentaciones atípicas debido a serotipos recientemente descritos de estos virus, algunos de ellos se han reportado en pacientes adultos. Se presenta caso de paciente masculino de 19 años, con antecedentes de dermatitis seborreica facial en tratamiento, que desarrolla una presentación atípica del síndrome pie, mano boca en contexto de un brote de esta patología en su academia militar. Luego del análisis epidemiológico, clínico e histopatológico, se diagnostica eccema coxsackium, una patología infrecuente en este grupo etario que contiene algunas particularidades destacables en relación con su manejo y estudio.

The hand mouth foot syndrome is a common pathology observed in children under 5 years, usually caused by coxsackie virus and enterovirus. There are exuberant clinical presentations, due to infrequent and emerging serotypes of these viruses, some of them manifesting in adult patients. A case of a 19 year old patient is presented, with a history of seborrheic dermatitis of the face and scalp in treatment, who develops an atypical clinical presentation of the hand foot mouth syndrome, intensely affecting the areas of seborrheic dermatitis on the face, in the context of an outbreak of this pathology in his military academy. After the epidemiological, clinical and histopathological analysis, eczema coxsackium is diagnosed, an infrequent pathology in this age group that contains some remarkable peculiarities in relation to its management.

Onicomadesis secundaria a enfermedad pie-mano-boca: una manifestación frecuente y motivo de preocupación de los padres / Onychomadesis secondary to hand-foot-mouth disease: a frequent manifestation and cause of concern for parents

INTRODUCCIÓN: Las alteraciones ungueales en niños provocan gran ansiedad en los padres y múltiples consultas en su mayoría innecesarias. La onicomadesis corresponde al despegamiento completo e indoloro de la lámina ungueal desde el pliegue proximal. Este hallazgo ungueal autoresolutivo se ha descrito como una complicación tardía de la enfermedad pie-mano-boca, exantema viral frecuente en la edad pediátrica. OBJETIVO: Reportar un caso pediátrico clásico de enfermedad pie-mano-boca que evolucionó con onicomadesis y revisión de la literatura. CASO CLÍNICO: Paciente masculino de 3 años de edad, con cuadro agudo de microampollas eritematosas, peribucales en un comienzo, luego brazos y manos, glúteos, muslo y pies, asintomático y sin compromiso del estado general. Se reali za diagnóstico clínico de enfermedad pie-mano-boca. Evoluciona con resolución total de lesiones cutáneas , pero al mes, desprendimiento completo de uñas, las que se recuperan con posterioridad. CONCLUSIÓN: El reconocimiento de la asociación entre enfermedad pie-mano-boca con onicomadesis nos permite orientar a los padres sobre un fenómeno benigno y transitorio que puede ocurrir como parte de la evolución de esta virosis, evitando así la ansiedad, derivación y tratamientos innecesarios.

INTRODUCTION: Nail alterations in children are an important cause of parent anxiety and derive in multiple and unnecessary consultations. The onychomadesis corresponds to the complete and pain less detachment of the nail plate from the proximal fold. This self-resolving nail finding has been described as a late complication of hand-foot-mouth disease, a frequent viral exanthema in the pedia tric age. OBJECTIVE: To describe a classic pediatric case of hand-foot-mouth disease with subsequent onychomadesis. CLINICAL CASE: A 3-years-old male patient with an acute presentation of acute erythe matous perioral papulovesicles, which extend to upper extremities and hands, buttocks, thighs and feet, asymptomatic, and without compromising general condition. Skin lesions resolve completely, but after one month, he develops detachment of the nails, with subsequent complete recovery. CONCLUSIONS: The recognition of this association will allow primary care physicians to guide the parents about a benign and self-resolving process that may occur as part of the evolution of hand-foot-mouth disease, thus avoiding unnecessary anxiety, referral and treatments.

Enfermedad de mano, pie y boca en un hospital del Callao, 2016 / Hand, foot, and mouth disease in a hospital in Callao in 2016

RESUMEN La enfermedad de mano, pie y boca (EMPB) es una enfermedad exantemática viral, causada principalmente por Coxsackie A16, con una sintomatología típica consistente en fiebre; exantema pápulo-vesicular en manos, pies y genitales; y un enantema ulceroso en boca. En el verano del 2016 se presentó una diversidad de casos en un hospital del Callao en niños y adultos, con una sintomatología compatible con EMPB; el diagnóstico fue clínico, se aplicó terapia de soporte con resolución final de síntomas. En la última década se han presentado reportes en algunos países con una afectación atípica causada por el Coxsackie A6, produciendo lesiones más extensas y en adultos. Sin embargo, el diagnóstico sigue siendo clínico, solo necesitando confirmación virológica en casos atípicos o cuando el diagnóstico no es claro. La importancia de este reporte radica en describir los casos del Callao ocurridos en el verano del 2016, para servir de apoyo a los profesionales de la salud en el diagnóstico y manejo de pacientes con similar sintomatología.

ABSTRACT Hand, foot, and mouth disease (HFMD) is an exanthematous viral disease caused mainly by Coxsackie A16 with a typical symptomatology of fever, papulovesicular rash on the hands, feet, and genitals, and an ulcerous enanthem in the mouth. In the summer of 2016, a variety of cases presented at a hospital in Callao in children and adults with a symptomatology consistent with HFMD. A clinical diagnosis was made, and support therapy was applied, resulting in the resolution of symptoms. In the last decade, reports have emerged in some countries of an atypical involvement caused by Coxsackie A6, producing lesions that are more widely distributed in adults. However, the diagnosis remains clinical, only requiring virological confirmation in atypical cases or when the diagnosis is unclear. The importance of this report stems from its description of the cases in Callao that occurred in the summer of 2016 and serve as an example for health professionals in the diagnosis and management of patients with similar symptomatology.

Expression of enterovirus 71 capsid protein VP1 in Escherichia coli and its clinical application

The VPl gene of enterovirus 71 (EV71) was synthesized, construct a recombinant plasmid pET15b/VP1 and expressed in E. coli BL21. The recombinant VP1 protein could specifically react with EV71-infected patient sera without the cross-reaction with serum antibodies of coxsackievirus A16 (CA16), A4, A5, B3 and B5 as well as echovirus 6. In acute and convalescent phases, IgM and IgG antibodies of 182 serum samples were detected by ELISA with recombinant VP1 protein as a coated antigen. The results showed that the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of IgM antibodies in serum samples for the diagnosis of EV71 infection were 90.1, 98.4, 98.8 and 88.7%, respectively; similarly, those of IgG antibodies in serum samples were 82.4, 89.1, 91.5 and 78.1%, respectively. Five of 80 samples (6.25%) from CA16infected patients were detected positive by ELISA with recombinant VP1 protein in which indicated the cross reactions and 0 of 5 samples from patients infected with other enteroviruses including CA4, CA5, CB3, CB5 and echovirus 6. Therefore, the recombinant VP1 protein of EV7l may provide a theoretical reference for establishing an effective antibody screening of IgM for EV71-infected patients with clinically suspected hand, foot, and mouth disease (HFMD).

Hand, foot, and mouth disease: Current scenario and Indian perspective.

Hand, foot, and mouth disease (HFMD), first reported in New Zealand in 1957 is caused by Coxsackievirus A16 (CVA16) and human enterovirus 71 (HEV71) and occasionally by Coxsackievirus A4-A7, A9, A10, B1-B3, and B5. This is characterized by erythematous papulo vesicular eruptions over hand, feet, perioral area, knees, buttocks and also intraorally mostly in the children. HFMD has been known for its self limiting course. Only small scale outbreaks have been reported from United States, Europe, Australia, Japan and Brazil for the first few decades. However, since 1997 the disease has conspicuously changed its behavior as noted in different Southeast Asian countries. There was sharp rise in incidence, severity, complications and even fatal outcomes that were almost unseen before that period. Following the near complete eradication of poliovirus, HEV71, the non-polio enterovirus, may become the greatest threat to cause significant neurological complications. This adds to the fact that effective therapy or vaccine is still a far reaching goal. There are reports of disease activity in different corners of India since 2004. Although of milder degree, continuous progress to affect larger parts of the country may indicate vulnerability of India from possible future fatal outbreaks. Low level of awareness among the health care providers may prove critical.

Enfermedad de manos, pies y boca en paciente adulto / Disease hand, foot and mouth in an adult patient

La enfermedad de manos, pies y boca es causada por el virus coxsackie A es extremadamente contagiosa y de duración limitada. Es característica de niños y muy eventualmente en adultos. Se asocia a fiebre, malestar general, linfoadenopatías tras las cuales aparece una erupción vesicular localizada en la boca que se rompen originando úlceras superficiales y se acompañan de la aparición de pápulas eritematosas en las palmas de las manos, en las plantas de los pies, que pasan a vesículas y luego se ulceran. No requiere tratamiento específico, es autolimitada, con un tiempo de duración de 1 a 2 semanas. Se presenta un caso de paciente femenina de 52 años de edad quien consulta por presentar lesiones ulcerativas en la cavidad bucal acompañada con sintomatología general. Antecedentes familiares y personales no contributorios. La paciente refiere inicio de la enfermedad actual hace aproximadamente 6 días cuando aparecieron lesiones vesiculo - ulcerativas en la mucosa bucal, concomitante con fiebre y malestar general. Refiere haber tenido contacto con una nieta que presentó el mismo cuadro clínico. No ha recibido tratamientos anteriores. Al examen clínico extrabucal se observa en la piel de las manos y en los pies lesiones papulomatosas y algunas ulcerativas, que causan molestias a la paciente. Al examen intrabucal se observa lesiones de naturaleza ulcerativa ubicadas en mucosa de los carrillos y pilar anterior amigdalino. Se le indico tratamiento sintomático. Se destaca la importancia de este caso en su presentación clínica ya que es una enfermedad frecuente en la infancia y siendo inusual en pacientes de edad adulta

Hand, foot and mouth disease is caused by the virus coxsackie A, is extremely contagious and of limited duration. Is typical of children and very eventually in adults. It associates to fever, general discomfort, linfoadenopatía after which a vesicular eruption appears located in the mouth, they break originating superficial ulcers and they accompany with the appearance of wheal and flare in the palms of the hands, in the plants of the feet, which go on to bladders and then ulcerate. It does not need specific treatment, is autolimited, with a time of duration from 1 to 2 weeks. It is presented a case of 52-year-old female patient of age, who consults for presenting ulcerative injuries in the oral cavity accompanied with general symptomatology. Family and personal precedents are not contributers. The patient recounts the beginning of the current disease approximately 6 days ago when appeared ulcerative bladders injuries in mucous mouth, concomitant with fever and general discomfort. She recounts to have had contact with a granddaughter who presented the same clinical picture. She has not received previous treatments. In the clinical extrabuccal examination is observed in the hand's skin and in the feet papulomatosas and some ulceratives injuries, which cause inconveniences to the patient. In the intrabuccal examination is observed injuries of ulcerative nature located in mucous of the pulleys and previous prop amigdalina. It was indicate symptomatic treatment. Is outlined the importance of this case in its clinical presentation since it is a frequent disease in the infancy and being unusual in patients of adult age

Echovirus 4 associated to hand, foot and mouth disease / Echovirus 4 associado à doença de mão, pé e boca

Hand, foot and mouth disease (HFMD) is a contagious enteroviral infection occurring primarily in children and characterized by vesicular palmoplantar eruptions and erosive stomatitis. Echovirus 4 (EV-4) has been commonly associated with aseptic meningitis. The association of HFMD with EV-4 has not been reported previously. Two samples of a 14-month child who presented mild fever, sores in the mouth, rash with blisters on the palm of hands and soles of feet were sent to Enteric Viruses Laboratory of Adolfo Lutz Institute. Clinical samples were inoculated in three different cell lines, and those which presented cytopathic effect (CPE), were submitted to Indirect Immunofluorescence Assay (IFA) and "one step" RT-PCR. Agarose gel electrophoresis from RT-PCR product, showed a product with 437 bp, which is characteristic of Enterovirus group. Echovirus 4 was identified by IFA. Although HFMD is a viral infection associated mainly with Enterovirus 71 (HEV-71) and Coxsackievirus A16 (CV-A16), our results demonstrate a diversity of serotype related to HFMD and stress the importance of epidemiological surveillance to this disease and its complications.

A Doença de Mão, Pé e Boca (DMPB) é uma infecção enteroviral contagiosa que ocorre principalmente em crianças sendo caracterizada por erupções palmoplantares vesiculares e estomatite. Echovirus 4 (EV-4) é comumente associado a meningite asséptica. A associação de DMPB por EV-4 não foi descrita anteriormente. Duas amostras provenientes de uma criança de 14 meses apresentando febre, secreções na garganta e exantemas nas palmas das mãos e dos pés, foram enviadas para o Laboratório de Vírus Entéricos do Instituto Adolfo Lutz. As amostras foram inoculadas em três diferentes linhagens celulares; aquelas que apresentaram efeito citopático (ECP), foram submetidas a ensaio de imunofluorescência indireta (IFI) e "one step" RT-PCR. A eletroforese em gel de agarose realizada com o produto de PCR apresentou um produto de 437pb, característico de grupo Enterovirus. O sorotipo EV-4 foi identificado por IFI. Apesar da DMPB ser uma infecção viral associada principalmente com Enterovirus 71 (HEV-71) e Coxsackievirus A16 (CV-A16), nossos resultados enfatizam a necessidade de estudos epidemiológicos e laboratoriais direcionados ao EV-4 como agente causador de DMPB.
