Síndrome de Ramsay Hunt en paciente epiléptico en Santander, Colombia: Reporte de caso

El Síndrome de Ramsay Hunt es una entidad infrecuente, con una incidencia de 5 por cada 100.000 personas por año. Esta condición se caracteriza por una reactivación del virus de la varicela-zoster en el nervio facial. Su diagnóstico implica un reto para el médico puesto que suele ser netamente clínico, con la aparición de una triada consistente en: otalgia, parálisis facial ipsilateral y vesículas en el canal auditivo. El objetivo del artículo es presentar el caso de una mujer de 49 años de edad, con antecedente de epilepsia en tratamiento anticonvulsivante, quien ingresa con la triada clínica antes descrita, asociada a visión borrosa derecha y vértigo. La paciente fue tratada con antivirales y corticoides orales, presentando una resolución clínica favorable dado una reducción de más del 50% de las lesiones cutáneas. No se identificaron diferencias respecto a la presentación clínica de este síndrome al compararse con pacientes no epilépticos.

Ramsay Hunt Syndrome is a rare entity, with an incidence of 5 per 100,000 people per year. This condition is characterized by a reactivation of the varicella-zoster virus in the facial nerve. Its diagnosis implies a challenge for the physician since it is usually a clinical diagnosis, with the appearance of a clinical triad consisting of: otalgia, ipsilateral facial paralysis and vesicles in the ear canal. The objective of the article is to present the case of a 49-year-old woman, with a history of epilepsy receiving anticonvulsant treatment, who was admitted with the aforementioned clinical triad, associated with blurred right vision and vertigo. The patient was treated with oral antiviral management and oral corticosteroids, presenting a favorable clinical resolution given a reduction of more than 50% of the skin lesions. No differences were identified regarding the clinical presentation of this syndrome when compared with non-epileptic patients.

Complications of herpes zoster hospitalizations in a reference hospital in Fortaleza-Ceará, 2009-2018 / Complicações de internações por herpes zoster em um hospital de referência em Fortaleza-Ceará, 2009-2018

Objective: the aim of this study was to relate sociodemographic, epidemiological and clinical conditions to the occurrence of severe cases of HZ in reference hospital of Fortaleza. Methods: this is a cross-sectional analytical study, based on medical records of patients admitted from 2009 to 2018. Pearson's x2 test or Fisher's exact test were used when appropriate. Results: we analyzed 196 medical records. The presence of complications occurred in 69.9%, the most affected region was the cranial (68.9%), and 1.5% died. The presence of vesicles (PR=1.37; 95%CI: 1.03-1.82; p=0.01) and the choice of antibiotic associated antiviral therapy (PR=0.58; 95%CI: 0.46-0.73; p=0.00) were significantly associated with the severity. Conclusions: the disease may be more severe at ages over 50. The presence of lesions in vesicles was associated with a higher prevalence of complications and the use of antibiotics and antivirals as a protective factor.

Breast carcinoma metastasis and Wolf's isotopic response

Abstract Wolf's isotopic phenomenon occurs when a new dermatosis appears on a site that has already healed from a previous dermatological disease of another etiology. This report describes the case of a 44-year-old female patient undergoing treatment for breast carcinoma who recently had brownish erythematous lesions appearing on the scar region of previous herpes zoster on the right hemithorax. Histopathology and immunohistochemistry examination confirmed skin metastasis of breast cancer. Herpes zoster scars require attention due to the possibility of an isotopic response as a facilitating factor in some dermatoses, sometimes severe ones, such as neoplasms.

Necrosis retiniana aguda por virus varicela zoster en un paciente inmunocompetente con seguimiento de la respuesta terapéutica mediante reacción de polimerasa en cadena / Acute retinal necrosis by varicella zoster virus in an immunocompetent patient with therapeutic follow up by PCR

Resumen Presentamos el caso de un varón de 63 años, inmunocompetente, con una necrosis retinal aguda (NRA) unilateral. Consultó por visión borrosa, dolor ocular, fotofobia y cefalea. Se confirmó una papilitis y coriorretinitis periférica asociada a vasculitis e isquemia retinal periférica. El estudio molecular por RPC de humor acuoso detectó la presencia de virus varicela zoster. El paciente fue tratado con terapia combinada con corticoesteroides orales, aciclovir oral/intravenoso, ganciclovir intravítreo semanal y luego valaciclovir oral por tres meses. Se demostró una disminución progresiva de la carga viral en el humor acuoso durante el tratamiento. El seguimiento mostró una mejoría del cuadro inflamatorio y una leve recuperación de la agudeza visual, sin embargo, finalmente presentó un desprendimiento de retina con pérdida casi total de la visión unilateral. La NRA es una complicación infrecuente provocada por algunos virus herpes con mal pronóstico visual, desenlace que puede ser mejorado con un diagnóstico y tratamiento precoz con antivirales. El tratamiento prolongado permite evitar la recaída y el compromiso contralateral.

Abstract We present the case of a 63-year-old immunocompetent man with unilateral acute retinal necrosis (ARN). He consulted for blurred vision, eye pain, photophobia, and headache. Papillitis and peripheal chorioretinitis associated with vasculitis and peripheral retinal ischemia was confirmed. PCR from aqueous humor sample detected varicella zoster virus. The patient was treated with a combined therapy of oral corticosteroids, oral / intravenous acyclovir along with weekly intravitreous ganciclovir doses followed by oral valaciclovir for three months. A progressive decrease in viral load in aqueous humor was demonstrated during treatment. Follow-up showed improvement in the inflammatory condition and a slight recovery of visual acuity, however, finally he presented a retinal detachment with total loss of one-sided vision. ARN is an uncommon complication caused by some herpesviruses with a poor visual prognosis, an outcome that can be improved with early diagnosis and treatment using appropriate antivirals. Prolonged treatment reduces relapse frequency and fellow eye compromise.

Meningitis aséptica por varicela zóster sin rash vesicular previo en paciente VIH positivo. Presentación de caso / Varicella Zoster aseptic meningitis without previous vesicular rash in VIH positive patient. Case report

Resumen Un cuadro de meningitis aséptica, en el contexto de un paciente inmunosuprimido con diagnóstico de infección por Virus de Inmunodeficiencia Humana (VIH), debe llevar a pensar en múltiples diagnósticos diferenciales. Entre estos, se incluye el virus varicela zóster (VVZ) como uno de los principales agentes causales de meningitis a líquido cefalorraquídeo claro. Su reactivación da lugar a múltiples manifestaciones neurológicas potencialmente mortales en las que se consideraba al rash vesicular, o exantema pápulo/vesículo/ costroso como un signo fundamental para su diagnóstico. No obstante, las lesiones cutáneas están ausentes en más de un tercio de los pacientes con compromiso del sistema nervioso central. A continuación, se presenta el caso de un paciente con infección por VIH que presenta cefalea más fiebre, con hallazgos en líquido cefalorraquídeo de pleocitosis neutrofílica y una prueba molecular confirmatoria para virus varicela zóster, en ausencia de rash vesicular previo que guiara hacia este diagnóstico. MÉD.UIS.2021;34(1): 91-9.

Abstract The clinical presentation of aseptic meningitis in the context of an immunosuppressed patient with a diagnosis of Human Immunodeficiency Virus (HIV) infection, should lead us to consider multiple differential diagnoses. Among these, the Varicella Zoster Virus (VZV) has been found as one of the main causative agents of clear cerebrospinal fluid meningitis. Its reactivation gives rise to multiple life-threatening neurological manifestations in which vesicular rash, or papule / vesicular / crusted rash was considered a fundamental sign for its diagnosis. However, skin lesions are absent in more than a third of patients with central nervous system involvement. Herein, we report a case of an HIV-infected patient with headache, fever and neutrophilic pleocytosis with FilmArray that confirms Varicella Zoster virus infection in an immunocompromised patient in the absence of vesicular rash. MÉD.UIS.2021;34(1): 91-9.

Number of cases of varicella and hospitalization in a pediatric reference hospital in brazil after introducing the vaccine / Avaliação do número de casos e do perfil de internações por varicela em hospital pediátrico após a introdução da vacina

ABSTRACT Objective: To assess the number of cases and the profile of hospitalizations from varicella after the introduction of the measles, mumps, rubella and varicella combination vaccine in the public health system. Methods: Retrospective study in an infectious diseases pediatric hospital of reference in Southeast Brazil. The cases with a clinical diagnosis of varicella, from January 2011 to June 2016, were assessed from pediatricians' medical records. The hospitalizations were classified into a pre-vaccine group and post-vaccine group, based on the date the vaccine was introduced (September 2013). Both groups were compared by age, sex, time of hospitalization, reason for hospitalization, hospital complications, duration of intensive care, and clinical outcome. Results: A total of 830 hospitalizations were recorded; 543 in the pre-vaccine period and 287 in the post-vaccine period, a reduction of 47.1% (p<0.001). In both periods, a similar profile in the hospitalizations was noticed: majority male; aged between one to five years old; most complications due to secondary causes (mainly skin infections); main outcome was clinical improvement and discharge from the hospital. In the pre-vaccine period, six deaths were recorded and two were recorded in the post-vaccine period. Conclusions: The profile of the hospitalizations was expected to stay the same since this study did not compare vaccinated with unvaccinated children, but hospitalizations before and after the vaccine was introduced. In accordance with the medical literature, we found a significant fall in the number of hospitalizations from varicella.

RESUMO Objetivo: Avaliar o número de casos e o perfil das internações por varicela após a introdução da vacina quádrupla viral na rede pública. Métodos: Estudo retrospectivo conduzido em hospital pediátrico referência em doenças infectocontagiosas na Região Sudeste do Brasil. Foram avaliados os casos com diagnóstico clínico de varicela, registrados em prontuário por médico pediatra, de janeiro de 2011 até junho de 2016. As internações foram classificadas em grupo pré-vacinal e grupo pós-vacinal, com base na data de introdução da vacina (setembro de 2013). Os grupos foram comparados em relação a: faixa etária, sexo, tempo de hospitalização, causas da internação, complicações hospitalares, tempo da internação em terapia intensiva e desfecho clínico. Resultados: Foram documentadas 830 internações, 543 no período pré-vacinal e 287 no pós-vacinal, ocorrendo redução de 47,1% nas internações (p<0,001). Em ambos os períodos, notou-se um perfil similar das internações, predominantemente: sexo masculino; faixa etária de um a cinco anos; por causas secundárias (principalmente infecções de pele); evoluindo com melhora clínica e alta hospitalar. Em relação ao número de óbitos, ocorreram seis no período pré-vacinal e dois no pós-vacinal. Conclusões: A manutenção do perfil das internações era esperada, visto que o trabalho não comparou crianças vacinadas com não vacinadas, e sim internações pré e pós-vacinais. Observou-se, em concordância com a literatura, queda substancial no número de internações por varicela.

A study on neurological manifestations of primary varicella zoster virus infection

@#Background & Objective: About 95% of the adult population has been infected with varicella zoster virus (VZV). It can involve any part of the nervous system. This study aimed to determine the spectrum of neurological manifestations in patients with primary varicella zoster virus infection, its clinical course and prognosis. Methods: This was an observational study of patients who presented with primary VZV infection in the Institute of Neurology, Madras Medical college, Chennai between August 2015 and February 2018. Patients with neurological manifestations due to VZV reactivation were not included in the study. Detailed history, clinical examination, blood investigations, MRI brain and whole spine, CSF analysis including viral studies, nerve conduction studies, EEG were analysed. All primary VZV patients were found to have characteristic chickenpox rash and/or its scar. The course of disease and clinical outcome after treatment were studied. Results:Among the 22 patients, 10 patients presented with VZV meningoencephalitis, 4 patients with Guillain-Barré syndrome (GBS), 2 patients with meningoencephalitis with cerebellitis, 2 patients with cerebellitis, 1 patient as acute disseminated encephalomyelitis ( ADEM), 1 patient as neuromyelitis optica (NMO), Two patients had acute stroke like deficits due to VZV vasculopathy. GBS and ADEM patients were treated with intravenous immunoglobulin and NMO patient was treated with intravenous methylprednisolone and they clinically improved after 4 weeks. There were two mortalities (9%). Conclusion: Meningoencephalitis followed by GBS were the main manifestations of primary VZV from Chennai, India

Implementation of Hospital Policy for Healthcare Workers and Patients Exposed to Varicella-Zoster Virus

Varicella-zoster virus (VZV) causes a highly contagious and generally benign, self-limited disease. However, in high-risk populations including immunocompromised patients, pregnant women, and neonates, VZV infection can be associated with significant morbidity and mortality. Healthcare-associated transmission of VZV occurs among healthcare workers (HCWs) and patients by airborne transmission or by direct contact with the index case. To minimize the risk of transmission in healthcare settings, all VZV-susceptible HCWs should be encouraged strongly to be immunized with the varicella vaccine. For post-exposure management, active immunization (varicella vaccine), passive immunization (varicella-zoster immune globulin) and/or antiviral agents, and isolation could be used in specific situations. To prevent the transmission of VZV infection in the hospital settings, the development and implementation of hospital policies for appropriate infection control is also warranted. This article reviews the general information and healthcare-associated transmission of VZV and summarizes the recommendations for the pre- and post-exposure management of HCWs and patients, in hospital settings.

Immunohistochemical Study for the Differential Diagnosis between Herpes Simplex and Varicella-zoster Infections / 대한피부과학회지

BACKGROUND: The clinical distinction between herpes simplex virus (HSV) and varicella-zoster virus(VZV) skin infections is sometimes difficult. Potentially, immunohistochemical method can distinguish HSV from VZV infection. However, immunohistochemical studies for the differentiation between them have rarely been reported. OBJECTIVE: The purpose is to investigate the usefulness of immunohistochemical staining in differentiation between HSV and VZV infections. METHODS: We studied 9 cases of herpes zoster, 4 cases of chicken pox, and 5 cases of herpes simplex with monoclonal antibody to VZV. Routine histopathologic findings of the cases were also evaluated. RESULTS: All cases of VZV infections stained with antibody to VZV, but none of HSV infection stained. In VZV infection, 25% of the cases showed strong or diffuse positive reaction, whereas the rest of them showed weak or focal pattern. Histopathologically, the degree of inflammation was significantly greater in HSV infection than in VZV infection. However, vaculitis was more frequently found in VZV infection than in HSV infection. CONCLUSION: We think immunohistochemistry with antibody to VZV is very useful in the differentiation between HSV and VZV infections, even if the reaction pattern may be so weak or focal, as careful interpretation is necessary.
