Onicomadesis asociada a la enfermedad de boca, mano, pie / Onychomadesis associated to mouth, hand, and foot disease

Introducción: la onicomadesis es el desprendimiento completo y espontáneo de la uña desde su extremo proximal, sin dolor o inflamación, consecutivo a la detención mitótica de la matriz ungular que conlleva a un cambio de su función. Objetivo: describir una serie de casos de onicomadesis atendidos en la consulta de Dermatología del Hospital Pediátrico Docente del Cerro, entre noviembre y diciembre del año 2017, después de presentar un cuadro clínico compatible con enfermedad boca, mano, pie, con la finalidad de contribuir al conocimiento de esta patema. Presentación de los casos: las edades estuvieron comprendidas en un rango entre 1 y 12 años, con solo 3 pacientes correspondientes al sexo masculino y solo uno con el color de la piel negra. Los días previos al padecimiento de la enfermedad boca, mano, pie se enmarcan entre 15 y 47 días de haber tenido los síntomas que indujeron al diagnóstico del citado morbo. El estudio virológico se efectuó en dos pacientes con presencia del Coxsackie A6. La evolución resultó satisfactoria en todos los casos. Conclusiones: los hallazgos, en general, coinciden con los mencionados en la literatura. Todos los pacientes presentaron semanas anteriores signos y síntomas compatibles con enfermedad boca, mano, pie. Es necesario orientar a los padres de los enfermos con este morbo, la posibilidad de la ocurrencia de onicomadesis como complicación, cuyo tratamiento es sintomático, seguido de buen pronóstico, para evitar la ansiedad familiar y los gastos de recursos innecesarios(AU)

Introduction: onychomadesis is the total and spontaneous detachment of the nail from its proximal end, without pain or inflammation, and following the mitotic halting of the nail matrix that leads to a change in its function. Objective: to describe a series of cases of onychomadesis attended in the Dermatology clinic of the Pediatric Teaching Hospital of Cerro, in the period of November to December of 2017, after presenting clinical manifestations compatible with mouth, hand, and foot disease, and in order to contribute to the knowledge of this pathology. Presentation of cases: ages were among 1 and 12 years old, with only 3 patients corresponding to the male sex and only one with black skin. The days before presenting symptoms of mouth, hand, and foot disease were between 15 and 47 days after having the symptoms that led to the diagnosis of the aforementioned disease. The virological study was carried out in two patients with the presence of Coxsackie A6. The evolution was satisfactory in all cases. Conclusions: in general the findings coincide with those mentioned in the literature. All patients presented previous signs and symptoms compatible with mouth, hand, and foot disease in the previous weeks. It is necessary to guide the parents of patients with this disease on the possibility of the onychomadesis occurrence as a complication, whose treatment is symptomatic, followed by a good prognosis to avoid family anxiety and the expense of unnecessary resources(AU)

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.

Onicomadesis asociada a la enfermedad de boca, mano y pie / Onychomadesis associated with mouth, hand and foot disease

La onicomadesis es el desprendimiento completo y espontáneo de la uña desde su extremo proximal, sin dolor o inflamación, consecutivo a la detención de la función de la matriz ungular. Es rara en los niños y puede afectar las uñas de las manos o de los pies. Puede ser secundaria a enfermedades sistémicas, enfermedad de Kawasaki, dermatosis ampollares, fármacos, paroniquia, estrés y radioterapia. Desde el año 2000, la enfermedad de boca, mano y pie (EBMP) se ha descrito como causa de onicomadesis y ha ocasionado brotes epidémicos en distintas regiones del mundo. La EBMP es una infección caracterizada por una estomatitis vesicular y erosiva asociada a una erupción vesicular palmoplantar. Afecta a los niños pequeños en verano y otoño, y es causada por el virus coxsackie. Presentamos un estudio que muestra la situación actual de la onicomadesis en niños de la Argentina, con una fuerte asociación entre esta alteración y EBMP previa, siendo, probablemente, una nueva manifestación de una enfermedad ya conocida.

Onychomadesis is the spontaneous, complete shedding of the nail from its proximal side, without pain or inflammation, following nail matrix arrest. This disorder is uncommon in children and it can occur in fingernails, toenails or both. It may be secondary to systemic disorders, Kawasaki disease, bullous dermatoses, drugs, paronychia, stress and radiotherapy. Since 2000, Hand, Foot, and Mouth Disease (HFMD) has been described as a cause of onychomadesis, and has been associated with outbreaks of this condition in different regions of the world. HFMD is an infection characterized by vesicular and erosive stomatitis in combination with a vesicular eruption in palms and soles. It occurs in small children during summer and autumn months, and it is caused by coxsackie virus. We present a study that reflects the current situation of onychomadesis in Argentinian children and shows a strong association between this disorder and HFMD, suggesting that onychomadesis is a new manifestation of a previously known disease.

Risk Factors for Neurologic Complications of Hand, Foot and Mouth Disease in the Republic of Korea, 2009

In 2009, the first outbreak of hand, foot and mouth disease (HFMD) or herpangina (HP) caused by enterovirus 71 occurred in the Republic of Korea. This study inquired into risk factors associated with complications of HFMD or HP. A retrospective medical records review was conducted on HFMD or HP patients for whom etiologic viruses had been verified in 2009. One hundred sixty-eight patients were examined for this investigation. Eighty patients were without complications while 88 were accompanied by complications, and 2 had expired. Enterovirus 71 subgenotype C4a was the most prevalent in number with 67 cases (54.9%). In the univariate analysis, the disease patterns of HFMD rather than HP, fever longer than 4 days, peak body temperature over 39degrees C, vomiting, headache, neurologic signs, serum glucose over 100 mg/dL, and having an enterovirus 71 as a causative virus were significant risk factors of the complications. After multiple logistic analysis, headache (Odds ratio [OR], 10.75; P < 0.001) and neurologic signs (OR, 42.76; P < 0.001) were found to be the most significant factors. Early detection and proper management of patients with aforementioned risk factors would be necessary in order to attain a better clinical outcome.

Miosite e rabdomiólise na doença mão-pé-boca na infância / Myositis and rhabdomyolysis in hand-foot-mouth disease in childhood

OBJETIVO: Relatar um caso de doença mão-pé-boca complicada por miosite, rabdomiólise e hepatite, interessante por ser a doença frequente em crianças e poder apresentar complicações graves, apesar de raras. DESCRIÇÃO DO CASO: Paciente de três anos de idade, sexo feminino, com história de febre por três dias, seguida pelo aparecimento de lesões ulceradas em mucosa oral e mialgia intensa. Após três dias, voltou a apresentar febre por mais dois dias (febre bifásica). Nesses dois dias, apresentou lesões eritematosas pelo corpo, principalmente nos pés, mãos e face, e procurou atendimento médico. Evoluiu com aumento de enzimas musculares e hepáticas (CPK com valor máximo de 345.007U/L, TGO 2041U/L, TGP 1589U/L, gama-GT 94U/L) e aumento transitório da creatinina sérica, com clearance de creatinina estimado pela estatura de 73mL/minuto/1,73m2 de superfície corporal. Houve melhora progressiva, com hidratação vigorosa e alcalinização da urina, sem necessidade de diálise. COMENTÁRIOS: Trata-se de uma criança com doença mão-pé-boca, com miosite, rabdomiólise e hepatite. São enfatizados os critérios clínicos laboratoriais para o diagnóstico e a importância da monitorização das complicações da doença.

OBJECTIVE: To report a hand-foot-mouth disease case, complicated by myositis, rhabdomyolisis and hepatitis, since this is a common disease in children and can result in rare but severe complications. CASE DESCRIPTION: A three-year-old girl with fever for three days, followed by the appearance of ulcerative lesions in the oral mucosa and severe muscular pain; after three days, she presented fever for two more days. At the same time, she had widespread erythematosus rash, especially in her hands, feet and face. She presented high levels of muscular and hepatic enzymes (maximum value of CPK 345.007IU/L, AST 2041IU/L, ALT 1589IU/L, GT 94IU/L), and transitory increase in serum creatinine (maximum value of 0.73mg/dL, creatinine clearance by Schwartz formula of 73mL/minute/1.73m2 of body surface). The patient improved progressively after vigorous hydration and urine alkalinization with sodium bicarbonate, without dialysis. COMMENTS: This is a case report of a child with hand-foot-mouth disease with myositis, rhabdomyolisis and hepatitis. Clinical and laboratory criteria for the diagnosis and the need to monitor complications are reviewed in this report.

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.
