ABSTRACT
INTRODUCCIÓN: La meningitis bacteriana aguda (MBA) y la encefalitis son infecciones graves y el retraso en el tratamiento determina mayor morbimortalidad. En 2015 la FDA. aprobó un panel de RPC múltiple, BioFire® Filmarray® meningitis-encefalitis (FA-ME), que desde el 2019 se encuentra disponible en nuestro hospital. OBJETIVOS: Estimar número de determinaciones positivas mediante FA-ME, evaluar concordancia con cultivo convencional (CC) y describir si FA-ME permitió realizar cambios en el tratamiento. MATERIAL Y MÉTODOS: Estudio retrospectivo, descriptivo, realizado durante 2019-2021 en el Hospital de Niños Pedro Elizalde. Se revisaron reportes de niños con meningitis, encefalitis y meningoencefalitis y líquido-cefalorraquídeo patológico a quienes se les realizó FA-ME. RESULTADOS: Se incluyó a 32 niños, edad promedio: 48 meses. Fueron positivas 13 determinaciones de FA-ME: siete bacterias y seis virus. En dos MBA obtuvo desarrollo mediante CC. Con FA-ME se ajustó el tratamiento en dos MBA y se acortó el tratamiento intravenoso (IV). DISCUSIÓN: Nuestro trabajo permitió conocer la etiología de cinco MBA con cultivo negativo, de las cuales dos habían recibido antimicrobianos, administrar quimioprofilaxis a contactos epidemiológicos, acortar el tratamiento IV y suministrar menos dosis de aciclovir; en concordancia con la literatura médica. CONCLUSIONES: FA-ME permitió identificar la etiología en cinco MBA que no desarrollaron en CC, ajustar tratamientos empíricos inadecuados y acortar duración del tratamiento parenteral.
BACKGROUND: Bacterial meningitis and encephalitis are life-threatening infections, a delay in its treatment is associated with high mortality. In 2015, FDA approved the Multiplex PCR FilmArray™ meningitis/encephalitis syndromic panel (FA-MEP), and it is available in our hospital since 2019. AIM: To estimate the number of positive FA-MEP, to evaluate the correlation to conventional culture (CC) results and to describe if the FA-MEP technology allowed changes in the treatment. METHODS: Retrospective analysis of children with meningitis, encephalitis and meningoencephalitis and pathological cerebrospinal fluid analysis between 2019-2021, who were subject to FA-MEP testing at the Pedro Elizalde Children's Hospital. RESULTS: 32 children, mean age: 48 months. 11 patients had positive FA-ME tests: 7 bacterial, 6 viral. 2 patients correlated with CC. Based on the FAMEP results, treatment was adjusted in 2 bacterial meningitis and the duration of intravenous treatment was shortened. DISCUSSION: Our study allowed to establish the etiology of 5 culture negative bacterial meningitis, (2 had prior antibiotics), administer chemoprophylaxis to close contacts, and to administer fewer doses of acyclovir. CONCLUSIONS: The FA-MEP allowed us to identify 5 bacterial meningitis that tested negative by CC and early adjustment of inappropriate empirical antibiotics and to shorten the duration of parenteral treatments.

Central nervous system infections are a medical emergency, due to their high fatality and sequelae. Timely treatment is essential, and should be initially indicated empirically by clinical guidance, without microbiological certainty. Hence the importance of cerebrospinal fluid (CSF) analysis as an etiological and therapeutic guide in the crucial initial hours of management. We report a 57-year-old woman consulting for fever and altered mental status. A brain CAT scan was normal. A lumbar puncture disclosed a CSF with predominance of neutrophils. Suspecting a bacterial meningitis, antimicrobial treatment was started but 48 hours after, the patient did not improve. A new lumbar puncture disclosed a CSF with predominance of lymphocytes. The lymphocyte shift prompted a PCR that was positive for herpes virus. The patient was treated with acyclovir with a good evolution.

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.

O mieloma múltiplo é a segunda neoplasia onco-hematológica mais comum, correspondendo a 1% das neoplasias malignas. Trata-se de uma condição subdiagnosticada, assim como a encefalite herpética. Entretanto, é comum a relação do mieloma com infecções, em decorrência do acometimento da imunidade humoral. A encefalite viral herpética tem como principal agente o vírus do herpes simples 1. O caso foi descrito baseado em um raciocínio clínico, visando contribuir para uma melhor caracterização do quadro clínico e do diagnóstico de duas entidades clínicas que possuem baixa suspeição diagnóstica e elevada morbimortalidade. Durante o curso da investigação, foram propostas variadas etiologias como responsáveis pelo rebaixamento do nível de consciência, levando a uma pesquisa de um espectro mais amplo de hipóteses diagnósticas, as quais precederam a confirmação do diagnóstico final. O quadro clínico atípico descrito apresentou obstáculos à suspeição diagnóstica correta, pois a ausência dos sinais e sintomas característicos de ambas as doenças levaram à pesquisa de um arsenal mais amplo de diagnósticos diferenciais. Assim, o atraso no diagnóstico e o início tardio do tratamento foram fatores que contribuíram para o prognóstico reservado do paciente. A associação dessas doenças é pouco descrita na literatura, de modo que mais estudos acerca do assunto se fazem necessários. (AU)
Multiple myeloma is the second most common onco-hematologic neoplasm, accounting for 1% of malignant neoplasms. As herpetic encephalitis, it is an underdiagnosed condition. However, the relation of myeloma with infections is common, due to the involvement of humoral immunity. Herpetic encephalitis has as its main etiological agent the herpes simplex virus 1. The case was described based on a clinical reasoning, aiming to contribute to a better characterization of the clinical picture and diagnosis of two entities that have low rates of diagnostic suspicion and high rates of morbidity and mortality. During the course of investigation, several etiologies were proposed as responsible for the decreased level of consciousness, leading to a search for a broader range of diagnostic hypotheses, which preceded confirmation of the final diagnosis. The atypical clinical picture described presented obstacles to the correct diagnostic suspicion, as the absence of symptoms and signs characteristic of both diseases led to the search for a broader arsenal of differential diagnoses. Thus, delayed diagnosis and late treatment were factors that contributed to the patient's reserved prognosis. The association of these diseases is poorly described in the literature, so further studies on that subject are required. (AU)

El uso cada vez más difundido de la terapia antirretroviral de gran actividad (TARGA) en el tratamiento de los pacientes con infección por el virus de la inmunodeficiencia humana (VIH) puede dar lugar a respuestas paradojales, caracterizadas por un empeoramiento de las manifestaciones clínicas o la reactivación de ciertas infecciones oportunistas, hasta ese momento subclínicas, como el Herpes varicela-zóster (HVZ). Este cuadro clínico se conoce desde hace años como síndrome inflamatorio de reconstitución inmune (SIRI). Puede afectar a más del 30% de los pacientes seropositivos para el VIH con un tiempo de aparición promedio de 8 a 12 semanas luego del inicio o cambio de TARGA. El HZ mucocutáneo representa entre el 7% al 12% de los episodios de SIRI en estos pacientes. En este trabajo, se presenta un paciente VIH seropositivo que desarrolló un episodio de HVZ cutáneo monometamérico asociado a compromiso del sistema nervioso central bajo la forma de un síndrome meningoencefalítico
The use of highly active antiretroviral therapy (HAART) in the management of human immunodeficiency virus (HIV) infection has resulted in a paradoxical response associated with the worsening of clinical symptoms of previously subclinical infections, such as herpes varicella-zoster (HVZ). This clinical picture is named as immune reconstitution inflammatory syndrome (IRIS). It may affect up to 30% of HIV-seropositive subjects within a wide range of time after the initiation or change of HAART, but mainly after 8 to 12 weeks. Mucocutaneous HZ accounts for 7%-12% of the diseases associated with HIV infection in patients with immune reconstitution from the administration of HAART. Here we present an HIV seropositive patient that developed an episode of cutaneous metameric eruption of HVZ associated with central nervous system involvement as meningoencephalitis syndrome.

ABSTRACT Objective: To report on a case of malignant hyperthermia in a child after a magnetic resonance imaging of the skull was performed using sevoflurane anesthesia. Case description: A 3-year-old boy admitted to the pediatric intensive care unit after presenting clinical and laboratory findings consistent with unspecified viral meningoencephalitis. While the patient was sedated, a magnetic resonance imaging of the skul was performed using propofol followed by the administration of sevoflurane through a laryngeal mask in order to continue anesthesia. Approximately three hours after the start of the procedure, the patient presented persistent tachycardia, tachypnea, generalized muscular stiffness and hyperthermia. With a diagnostic hypothesis of malignant hyperthermia, dantrolene was then administered, which immediately induced muscle stiffness, tachycardia, tachypnea and reduced body temperature. Comments: Malignant hyperthermia is a rare pharmacogenetic syndrome characterized by a severe hypermetabolic reaction after the administration of halogenated inhalational anesthetics or depolarizing muscle relaxants such as succinylcholine, or both. Although it is a potentially fatal disease, the rapid administration of continued doses dantrolene has drastically reduced the morbidity and mortality of the disease.
RESUMO Objetivo: Relatar um caso de hipertermia maligna em criança após exame de ressonância magnética de crânio realizada sob efeito anestésico de sevoflurano. Descrição do caso: Menino de três anos de idade, admitido na Unidade de Terapia Intensiva Pediátrica (UTIP) após apresentar quadros clínico e laboratorial compatíveis com meningoencefalite viral não especificada. Foi realizado um exame de ressonância magnética de crânio com sedação utilizando, na indução anestésica, o propofol seguido pela administração de sevoflurano por meio de máscara laríngea para manutenção anestésica. Aproximadamente três horas após o início do procedimento, o paciente apresentou taquicardia, taquipneia, rigidez muscular generalizada e hipertermia persistentes. Com hipótese diagnóstica de hipertermia maligna, foi então administrado dantrolene, que fez ceder de forma imediata a rigidez muscular, a taquicardia, a taquipneia e reduziu a temperatura corporal. Comentários: A hipertermia maligna é uma síndrome farmacogenética rara, que se caracteriza por reação hipermetabólica grave após administração de anestésicos inalatórios halogenados e/ou relaxantes musculares despolarizantes, como a succinilcolina. Apesar de ser uma doença potencialmente fatal, a rápida administração de dantrolene, junto às doses de manutenção, tem reduzido drasticamente a morbimortalidade da doença.

La meningitis linfocítica recurrente o meningitis de Mollaret es una entidad asociada a un gran número de etiologías infecciosas, autoinmunes, toxicológicas y neoplásicas. En la actualidad el virus herpes simple tipo 2 (HSV-2) es el agente más frecuentemente aislado. Afecta frecuentemente a mujeres de mediana edad y tiende a autolimitarse sin secuelas dentro de la primera semana de inicio de síntomas. El diagnóstico se basa en la detección de ácidos nucleicos virales en el líquido cefalorraquídeo. Al momento no se ha demostrado beneficio en el uso de tratamiento antiviral en la prevención de recurrencias.
Recurrent lymphocytic meningitis or Mollaret´s meningitis is a rare condition caused by a number of infectious, autoimmune, toxic and neoplastic diseases. Herpes simplex type 2 is the most commonly isolated agent. It usually compromises middle aged women, with a self-limited clinical presentation that resolves within a week leaving no sequelae. Its diagnosis is mainly based on nucleic acid detection on cerebrospinal fluid. Antiviral prophylaxis has not shown conclusive to avoid recurrences.

A meningite recorrente linfocítica benigna ou meningite de Mollaret, inicialmente descrita pelo neurologista francês Pierre Mollaret em 1944, é uma condição relativamente rara, benigna mas incapacitante durante os seus períodos de agudização. Trata-se de quadro inï¬amatório meníngeo recorrente devido a reativação de infecção pelo herpes simples vírus, particularmente o herpesvirus do tipo 2 (HSV-2). Pode ser reconhecida a partir do seu quadro clínico de meningismo agudo, perfil liquórico linfocítico e identificação do genoma viral por PCR no líquor. Aciclovir e seus derivados podem ser utilizado no seu tratamento ou na sua profilaxia. Sua identificação é importante no sentido de se excluir outras causas de quadros meníngeos recorrentes.
Benign recurrent lymphocytic meningitis or Mollaret's meningitis (MM) was frst described by the French neurologist Pierre Mollaret in 1944. MM is a relatively rare, benign but disabling condition. MM is a recurrent meningeal inï¬ammatory illness due to reactivation of herpes simplex virus infection, particularly herpesvirus type 2 (HSV-2). It can be recognized from its clinical picture of acute meningism, lymphocytic CSF profle and by the identifcation of the viral genome in the CSF by PCR. Acyclovir and its derivatives may be used for its treatment or prophylaxis. The identifcation of MM is important in order to exclude other causes of recurrent meningeal conditions.

RESUMEN La retinitis necrotizante aguda, es una necrosis retinal de todas las capas de la retina. Se caracteriza por necrosis fibrinoides de la pared de los vasos y oclusión vascular. Se presentó un caso de una paciente de 42 años de edad, con pérdida brusca de la visión del ojo derecho, con una semana de evolución. Al examen oftalmológico se observó haze vítreo 2+, edema sucio del disco óptico, con borramiento de todos sus bordes. Presencia de exudación blanca-amarillenta retiniana extensa, en toda la periferia y área ecuatorial asociada a hemorragias intraretinianas. Se realizó además del examen fundoscòpico toma de muestra de humor acuoso para reacción en cadena de la polimerasa y angiografía fluoresceínica. Los signos fundoscópicos de la paciente, así como las anomalías detectadas en la angiografía fluoresceínica sugirieron el diagnóstico clínico de síndrome de necrosis retinal aguda. Se confirmó el diagnóstico etiológico viral, semanas después por el resultado de polimerasa. Se practicó la terapéutica médica y fotocoagulación laser focal retiniano correspondiente, asociado a cirugía del desprendimiento de retina mixto mediante vitrectomía pars plana y se logró la re aplicación de la retina.
ABSTRACT The acute necrotizing retinitis is a retinal necrosis of all the retinal layers. It is characterized by fibrinoid necrosis of the vases' wall and vascular occlusion. The case presented is the case of a female patient aged 42 years, who suffers sudden loss of the left eye vision, with a week of evolution. At the ophthalmologic examination it was observed a 2+ vitreous haze, dirty edema of the optic disk, with effacement of all of its margins. There it was an extended white-yellowish retinal exudation in the entire periphery and the equatorial area, associated to intra-retinal hemorrhages. Besides the funduscopic examination, it was taken a sample of the aqueous humor for a polymerase chain reaction (PCR) and fluorescein angiography. The patient's funduscopic signs, and also the anomalies detected in the fluorescein angiography suggested the clinical diagnosis of acute retinal necrosis syndrome. After several weeks, the viral etiologic diagnosis was confirmed by polymerase chain reaction. It was practiced the correspondent medical therapeutics and focal retinal laser coagulation associated to mixt retinal detachment through pars plana vitrectomy; the retina reapplication was achieved.

Abstract: Background: There is a lack of evidence to support acyclovir administration in pityriasis rosea. Objective: To determine the efficacy of acyclovir in patients with typical pityriasis rosea. Methods: A systematic review and meta-analysis of experimental studies was performed in MEDLINE, SCOPUS, EMBASE and others, from January 1990 to October 2016 on acyclovir for pityriasis rosea. Random effect model was used to find the pooled Risk Ratio. Outcomes, evaluated between weeks 1 to 8, were regression of lesions, cessation of lesions, decrease of symptoms and duration of disease. Comparisons were acyclovir vs. placebo; acyclovir vs. symptomatic treatment; acyclovir vs. antibiotic; acyclovir vs. observation and combined therapy (acyclovir plus symptomatic treatment) vs. symptomatic treatment alone. Results: Seven papers were analyzed with 324 participants, of which 159 received acyclovir and 165 were controls. Acyclovir was superior to placebo for complete regression of lesions at week 1 (Risk Ratio 5.72, CI95% 2.36-13.88). However, combined therapy was not superior to symptomatic treatment at week 4 (Risk Ratio 1.46, CI95% 0.93-2.29). Individual studies showed the superiority of acyclovir for the control of symptoms and pruritus. Study limitations: We faced differences designs of trials and inconsistency between reports. Conclusion: Symptomatic treatment is a reasonable option for pityriasis rosea, and the addition of acyclovir is justified for the control of symptoms and pruritus.

Abstract Introduction Idiopathic sudden sensorineural hearing loss (ISSNHL) is hearing loss of at least 30 dB in at least 3 contiguous frequencies within at least 72 hours. There are many different theories to explain it, and many differentmodalities are used for its management, such as: systemic steroids (SSs), intratympanic steroid injection (ITSI), hyperbaric oxygen therapy (HOT), antiviral drugs, and vasodilators or vasoactive substances. Objectives This study aims to evaluate the efficacy of the combination of the most common treatmentmodalities of ISSNHL and to compare the results if HOTwas not one of the treatment modalities administered. Methods The study was conducted with 22 ISSNHL patients with ages ranging from 34 to 58 years. The patients were divided into 2 groups; group A included 11 patients managed by SSs, ITSI, antiviral therapy, and HOT simultaneously, and group B included 11 patients exposed to the aforementioned modalities, with the exception of HOT. Results After one month, all of the patients in group A showed total improvement in hearing in all frequencies, with pure tone average (PTA) of 18.1 ± 2.2, while in group B, 5/11 (45.5%) patients showed total improvement, and 6 /11 (54.5%) patients showed partial improvement, with a total mean PTA of 28.1 ± 8.7. Conclusion The early administration of HOT in combination with other clinically approved modalities (SSs, ITSI, antiviral therapy) provides better results than the administration of the same modalities, with the exception of HOT, in the treatment of ISSNHL.

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.

ABSTRACT Purpose: To determine the outcomes of penetrating keratoplasty (PK) for treatment of corneal scarring caused by Herpes simplex virus (HSV) keratitis, and whether the corneal scar type affects treatment outcome. Methods: A retrospective analysis of patients who underwent PK for HSV-related corneal scarring between January 2008 and July 2011 was performed. The patients were categorized into two groups. Group 1 consisted of patients with a quiescent herpetic corneal scar and group 2 consisted of patients who developed a corneal descemetocele or perforation secondary to persistent epithelial defects with no active stromal inflammation. The mean follow-up was 21.30 ± 14.59 months. The main parameters evaluated were recurrence of herpetic keratitis, graft rejection, graft failure, visual acuity, and graft survival rate. Results: There were 42 patients in group 1 and 13 in group 2. Preoperative BCVA varied from hand movements to 0.7 logMAR. Postoperatively, 34 patients (61.8%) achieved visual acuity of 0.6 logMAR or more. Recurrence of HSV keratitis was noted in 12 (28.57%) eyes in group 1 and 4 (30.76%) eyes in group 2 (p=0.40). Graft rejection occurred in 4 eyes (9.52%) in group 1 and in 3 (23.07%) eyes in group 2 (p=0.58). The 1-, 2-, and 3-year graft survival rates were 91.9%, 76.0%, and 65.1% in group 1, and 89.5%, 76.0%, and 63.6% in group 2 (p=0.91), respectively. Conclusions: Although there were different recurrence and graft rejection rates for two groups, the graft survival rates at 3 years were similar. According to our results, without inflammation, corneal herpetic scarring with a descemetocele or perforation achieved similar graft survival rates with quiescent herpetic corneal scars.
RESUMO Objetivo: Determinar os resultados da ceratoplastia penetrante (PK) para o tratamento da cicatriz da córnea consequente à ceratite por Herpes simplex vírus (HSV), e se o tipo de cicatriz na córnea afeta o resultado cirúrgico. Métodos: Foi realizada análise retrospectiva dos pacientes, submetidos à PK para a cicatriz da córnea relacionados com o HSV entre janeiro de 2008 e julho de 2011. Os pacientes foram divididos em dois grupos. Grupo 1 consistiu de pacientes que tiveram cicatriz corneana herpética quiescente e grupo 2 consistiu de pacientes que desenvolveram descemetocele ou perfuração córnea secundária a defeitos epiteliais persistentes sem inflamação estromal ativa. O seguimento médio foi de 21,30 ± 14,59 meses. Os principais parâmetros avaliados foram recorrência de ceratite herpética, rejeição de enxerto, falência do enxerto, acuidade visual e taxa de sobrevida do enxerto. Resultados: Foram avaliados 42 pacientes do grupo 1 e 13 doentes do grupo 2. Acuidade visual pré-operatória variou de movimentos das mãos (HM) para 0,7 logMAR. No pós-operatório, 34 pacientes (61,8%) atingiram acuidade visual de 0,6 logMAR ou melhor. Doze olhos (28,57%) tiveram recorrência de HSV ceratite no grupo 1, e quatro olhos (30,76%) tiveram recorrência no grupo 2 (p=0,40). A rejeição do enxerto ocorreu em 4 olhos (9,52%) no grupo 1, e em 3 olhos do grupo 2 (23,07%; p=0,58), taxa de sobrevivência do enxerto foi de 91,9% a 1 ano, 76,0% aos 2 anos e 65,1% aos 3 anos no grupo 1, e 89,5% a 1 ano, 76,0% aos 2 anos e 63,6% aos 3 anos no grupo 2 (p=0,91). Conclusões: Embora diferentes taxas de recorrência e de rejeição do enxerto foram encontradas nos dois grupos, a taxa de sobrevida do enxerto em 3 anos foi semelhantes nos dois grupos. De acordo com nossos resultados, em casos sem inflamação, a cicatriz herpética da córnea com descemetocele ou perfuração demonstra as taxas de sobrevivência do enxerto semelhantes às da cicatriz corneana herpética quiescente.

Zóster é uma doença viral pelo qual o mecanismo de reativação, ainda é pouco compreendido. Entretanto, parece estar relacionado com algum tipo de deficiência na imunidade, além do estresse também ser apontado como fator desencadeante. O diagnóstico, na maioria das vezes, é eminentemente clínico, usualmente determinado por lesões vesículobolhosas que envolvem a pele ao longo do trajeto do nervo branquial. O objetivo desse trabalho é relatar um caso clínico de uma paciente, 21 anos de idade, diagnosticada com zóster e comprometimento do nervo trigêmeo, nos ramos oftálmico, maxilar e mandibular.
