[Eccema herpético en una paciente con dermatitis atópica].

Background: Eczema herpeticum is an infection caused by herpes simplex virus in patients with atopic dermatitis, among its complications we can find meningitis, encephalitis, acute liver failure, and Staphylococcus aureus infection. Case report: We report the case of a female patient of 5 years of age, with a history of atopic dermatitis complicated by eczema herpeticum, who was treated initially without relief. Her hospital stay was complicated with cross infections, which prolonged her course. Dermatology diagnosed eczema herpeticum. Immediately after the start of treatment, the patient showed improvement. Conclusions: Eczema herpeticum is a rare complication of atopic dermatitis, it must be suspected based on patient history and physical examination. Therefore, early recognition and diagnosis are of clinical importance. Without an appropriate approach, these patients can present shock, sepsis, and death.

Antecedentes: El eccema herpético es una infección causada por el virus del herpes simple, que afecta a pacientes con dermatitis atópica. Las principales complicaciones son meningitis, encefalitis, insuficiencia hepática aguda e infección por Staphylococcus aureus. Reporte de caso: Paciente pediátrica de 5 años, con antecedente de dermatitis atópica complicada con eccema herpético, que recibió tratamiento sin reacción satisfactoria. Durante la hospitalización tuvo infecciones nosocomiales que prolongaron su estancia. Luego de la evaluación por personal del servicio de Dermatología se estableció el diagnóstico de eccema herpético, con adecuado tratamiento, seguimiento y egreso sin complicaciones. Conclusiones: El eccema herpético es una complicación rara de la dermatitis atópica, que debe diagnosticarse con base en los antecedentes personales patológicos y la exploración física adecuada. La atención oportuna es de relevancia clínica, pues los pacientes pueden tener complicación serias (choque, sepsis, incluso la muerte). Palabras clave: Eccema herpético; dermatitis atópica; infección nosocomial; Staphylococcus aureus.

Erupción variceliforme de Kaposi y enfermedad de Darier / Kaposi's varicelliform rash and Darier's disease

La erupción variceliforme de Kaposi es una infección cutánea diseminada, causada en la mayor parte de los casos por el virus Herpes simple tipo 1. Se suele presentar en pacientes con alteraciones preexistentes de la barrera cutánea, especialmente en niños con dermatitis atópica. Se comunica el caso de un paciente de 84 años, quien negaba enfermedades cutáneas previas, que consultó por lesiones dolorosas y pruriginosas, en la piel del tórax y el abdomen, de 3 semanas de evolución. Con sospecha de una enfermedad infecciosa viral, bacteriana, ampollar o neutrofílica, se realizó inmunofluorescencia directa para herpes, cultivo y biopsia de piel para estudio histológico. La inmunofluorescencia fue positiva para Herpes simple tipo 1 y el estudio histopatológico mostró cambios compatibles con infección herpética y enfermedad de Darier. La enfermedad de Darier es una genodermatosis infrecuente que se suele manifestar en la adolescencia. Si bien su diagnóstico en la ancianidad es excepcional, este caso ilustra que se debe considerar en todos los pacientes que presenten erupción variceliforme. (AU)

Kaposi's varicelliform rash is a disseminated cutaneous infection, caused by Herpes virus 1. It usually presents in patients with pre-existing skin barrier disorders, especially in children with atopic dermatitis. We report the case of an 84-year-old patient, who reported having no previous skin diseases, who consulted for painful, itchy, 3-week-old skin lesions. As we suspected viral, bacterial, bullous or neutrophilic disease, direct immunofluorescence, culture, and skin biopsy for histological study were performed. Immunofluorescence was positive for Herpes simplex type 1 and the histopathological study showed changes compatible with herpetic infection and Darier's disease. Darier's disease is a rare genodermatosis that usually manifests in adolescence. Although its diagnosis in old age is anecdotal, it should be considered in patients with a varicelliform rash. (AU)

Eczema herpeticum in children: clinical features and factors predictive of hospitalization.

OBJECTIVE: To describe the clinical characteristics of pediatric patients with eczema herpeticum and to determine the predictors of hospitalization, and recurrence and repeat episodes. STUDY DESIGN: A retrospective cohort study of patients 0-18 years of age diagnosed with eczema herpeticum between May 2000 and April 2009 was carried out at a tertiary pediatric care center in Canada. Seventy-nine patients were included. The primary outcome was hospitalization; secondary outcomes were recurrent and repeat episodes of eczema herpeticum. RESULTS: At presentation, 76% of 79 patients with eczema herpeticum had a generalized eruption, 56% had fever, 37% had systemic symptoms, and 10% had eye involvement (keratoconjunctivitis). Forty-five patients (57%) were hospitalized. Predictors for hospitalization included male sex (OR = 3.09; 95% CI, 1.20-7.95, P = .017), fever (OR = 5.75; 95% CI, 2.17-15.26, P < .001), systemic symptoms (OR = 2.84; 95% CI, 1.06-7.62, P = .035), and age <1 year (OR = 7.17; 95% CI, 2.17-23.72, P = .001). Recurrence rate (<1 month) was 8.9% and rate of repeat episodes (>1 month) was 16%. Hospitalized patients were more likely to have a repeat episode (OR = 8.25; 95% CI, 0.99-68.69, P = .05). Patients with a previous history of eczema herpeticum had increased likelihood of early recurrence (OR = 6.80; 95% CI, 0.99-46.62, P = .05) and repeat episodes (OR = 9.43; 95% CI, 1.52-55.9, P = .01). CONCLUSIONS: Predictors of hospitalization in this cohort included male sex, age <1 year, fever, and systemic symptoms at presentation. Hospitalized patients may be at risk for repeat episodes of eczema herpeticum.

[Eczema herpeticum caused by herpes simplex virus type 2. Review of the literature about one case]. / Eccema herpético por virus herpes simplex tipo 2. Revisión de la literatura a propósito de un caso.

Eczema herpeticum is an extensive vesicular eruption caused by cutaneous dissemination of herpes simplex virus in patients who have underlying skin conditions or epidermal barrier disruption. Herpes simplex virus type 1 (HSV 1) is the most common etiology. This is the first report in Chile of a case of eczema herpeticum caused by HSV 2 in a patient with Darier's disease, We review the literature and emphasize the use of sensitive and specific assays as real time polymerase chain reaction, that allow to initiate timely the correct treatment.

El eccema herpético es una erupción vesicular extensa causada por la diseminación cutánea del virus herpes simplex, en pacientes con trastornos cutáneos previos o daño de la barrera epidérmica. La etiología más frecuente es virus herpes simplex tipo 1 (VHS 1), aunque se han reportado casos de virus herpes simplex tipo 2 (VHS 2). Presentamos el primer reporte en Chile de eccema herpético por VHS 2 en un paciente con enfermedad de Darier. Realizamos una revisión de la literatura médica y destacamos la importancia del uso de técnicas sensibles y específicas como la reacción de polimerasa en cadena (RPC) en tiempo real, que posibilitan el inicio precoz de la terapéutica correcta.

Kaposi's varicelliform eruption in a patient with healing peribucal dermabrasion.

Kaposi varicelliform eruption (KVE) is the name given to a distinct cutaneous eruption caused by Herpesvirus hominis types 1 and 2, vaccinia virus, or coxsackie A16 virus, superimposed on a preexisting dermatosis. A delay in diagnosing this condition may result in intense pain and rapid spread of the cutaneous lesions. We report a patient who underwent perioral dermabrasion for wrinkles who developed KVE secondary to herpes simplex virus infection.

Diversas afecçöes cutâneas, em especial a dermatite atópica , säo suscetíveis a superinfecçäo por vírus, mais freqüentemente do herpes simples, com o desenvolvimento de quadro cutâneo agudo, regional ou disseminado, ocasionalmente fatal, denominado erupçäo variceliforme de Kaposi(EVK). A casuística brasileira de EVK inclui observaçöes feitas em portadores de pênfigo foliáceo(PF) nas áreas endêmicas desta bulose. Os autores apresentam e discutem um caso de EVK complicando PF, observado em pacientes oriundo do nordeste do Estado do Pará, que se encontrava em tratamento com altas doses diárias de corticóide.

Erupción variceliforme de Kaposi / [Kaposi's varicellifrom eruption]

Se describen dos lactantes atacados de Eczema atópico complicado con Erupción Variceliforme de Kaposi. En uno de ellos el ambiente familiar estaba libre de infecciones virósicas, aparentemente; en el otro caso una hermana padecía de herpes recidivante. El primero recibió Cloromicetina y curó en pocos días; el otro caso se complicó con grave proceso pulmonar y se trató con Novobiocina, Sigmamicina y Gamma-globulina, curando después de una evolución prolongada. Se actualizan conceptos sobre E.V.K. y las complicaciones del Herpes simple y de la Vacunación antivariólica.

Two infants with atopic eczema and Kaposi's Varicelliform Eruption are reported. The environment was free of virus infections in one of the patients, while the other had a sister suffering recurrent herpes. The former received Chloromycetin and cured in a few days; the latter had a severe pulmonary infection and received Novobiocin, Sigmamycin and Gamma-Globulin, recovering finally. Modern concepts about the pathogenesis of Kaposi's Varicelliform Eruption and the complications of Herpes Simplex and Vaccinia are synthesized.
