ABSTRACT
Resumen INTRODUCCIÓN: La varicela es una enfermedad infecciosa frecuente y altamente contagiosa, producida por el virus Varicella Zoster. Tradicionalmente se ha recomendado tratarla en forma sintomática, ya que existe controversia en relación a la utilidad del tratamiento antiviral, en especial en niños y adolescentes. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos tres revisiones sistemáticas, que en conjunto incluyen tres estudios primarios, todos correspondientes a ensayos aleatorizados. Concluimos que el uso de aciclovir podría no disminuir las complicaciones asociadas, y no está claro si disminuye las lesiones o el prurito porque la certeza de la evidencia es muy baja.
Abstract INTRODUCTION: Varicella (chickenpox) is a frequent and highly contagious infectious disease, caused by the Varicella zoster virus. Traditionally, it has been recommended to focus on the management of symptoms, since there is controversy about the role of antivirals, particularly in children and adolescents. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified three systematic reviews including three studies overall, all of them corresponding to randomized trials. We concluded the use of acyclovir might not decrease the associated complications, and it is not clear whether it reduces lesions or itching because the certainty of the evidence is very low.

To find spectrum of various dermatological manifestations during hepatitis "C" virus infection in local population of hyderabad. This descriptive study was conducted in medicine department of Isra University Hospital Hyderabad from January 2011 to June 2012. A total of 325 anti-HCV positive patients were enrolled. All patients were subjected to detailed history, careful clinical examination of skin by a dermatologist to diagnose skin disease. All data was analyzed using statistical package SPSS 14.0. A total of 325 HCV positive patients [61% males and 39% females] were enrolled in this study. Mean age was 43 [SD+10 years], ranging from 15 to 78 years. About 41% had one or more dermatologic manifestations. Pruritis was the leading manifestation found in 11%, lichen planus [oral and cutaneous] was next to be found in 6.7% patients and hyperpigmentation in 5.2% patients. Urticaria [acute and chronic] was next counting in 5.23%. Jaundice, alopecia and vitiligo were seen in 4.9% each. Dry skin and interferon injection site erythema were observed in 4.6% patients each. Cutaneous vasculitis was noticed in 3.6% each, while photosensitivity, psoriasis and Raynaud's phenomenon were seen in 1.8%, 2.5%, 1.5% patients respectively. Dermatological manifestations are very common in patients with chronic HCV infection and when confronted with a suspected skin lesion, patient should be screened for it. Epidemiological studies are essential to determine the real prevalence of other dermatoses during course of HCV infection
