    Full Text Available Since the late 1970s, canine parvovirus type 2 (CPV-2 has emerged as a causative agent of fatal severe acute hemorrhagic enteritis in dogs. To date, three antigenic types of CPV-2 were described worldwide (CPV-2a/b/c. This study was conducted to determine the variants of CPV-2 circulating in dogs from the Cuiabá Municipality in Midwestern Brazil. Out of 50 fecal samples, collected between 2009 and 2011, 27 tested positive for CPV-2. A 583 bp fragment of the VP2 gene was amplified by PCR, 13 representative samples were analyzed further by DNA sequencing. All strains were characterized as CPV-2c, displayed a low genetic variability although observed several amino acid substitution. These findings indicated that CPV-2c has been circulating in dogs from the Cuiabá Municipality in Midwestern Brazil.Desde o final dos anos de 1970, o parvovírus canino tipo 2 (CPV-2 tem emergido como agente de severa e fatal enterite hemorrágica, principalmente em cães com idade inferior a seis meses. Três variantes antigênicas de CPV-2 foram descritas mundialmente (CPV-2a/b/c. O objetivo do estudo foi determinar a presença do CPV-2 e suas variantes circulantes em cães no Município de Cuiabá, Centro-oeste, Brasil. Das 50 amostras fecais, coletadas entre 2009 e 2011, 27 foram positivas para CPV-2 na PCR, sendo 13 analisadas pelo sequenciamento de um fragmento de 583 pares de base do gene VP2. Todas as cepas foram caracterizadas como CPV-2c e apresentaram baixa variabilidade genética. Estes achados indicaram que o CPV-2c está circulando na população canina do Município de Cuiabá, Região Centro-Oeste do Brasil.

    Full Text Available Objetivos: Determinar la presencia y relación del virus herpes simple tipo 2 (VHS-2 en mujeres con diferentes grados de lesiones preinvasivas de cuello uterino. Materiales y métodos: Se estudiaron 176 mujeres con lesiones preinvasivas de cuello uterino y 40 mujeres como grupo control con cuello uterino sano, que asistieron a la consulta ginecológica en diferentes centros de salud, durante los años 2002-2005 en Maracaibo-Venezuela. A las pacientes se les tomó un hisopado del exocervix y una biopsia dirigida del sitio de la lesión por colposcopía. La determinación de VHS-2 se realizó a través de inmunofluorescencia directa. Resultados: La presencia de infección por VHS-2 fue 44 /176 (25%. El mayor número de VHS-2 se obtuvo en las pacientes con grado de lesión tipo NIC II (66,7%. El mayor porcentaje de infección por VHS-2 se determinó en las pacientes que iniciaron sus relaciones sexuales entre los 15 y 20 años (34,5%, las relaciones sexuales diarias (50%, así como relaciones de tipo orogenital fueron consideradas las conductas de mayor riesgo para adquirir la infección. Conclusiones: No se evidenció una relación directa entre VHS-2 y la presencia de cáncer. Los factores de riesgo asociados con la infección son similares a otras ITS, y están ligados con la conducta sexual y hábitos propios del individuo.

    Full Text Available OBJETIVO: Determinar la seroprevalencia de infección por el virus herpes simplex tipo 2 y los factores epidemiológicos asociados a ella, en tres grupos de población femenina de la Ciudad de México. MATERIAL Y MÉTODOS: Estudio transversal efectuado en el año 2000, que incluyó mujeres de la Ciudad de México diagnosticadas con cáncer de mama, cáncer cervical , y mujeres de población general negativas al Papanicolaou. Todas las participantes proporcionaron su consentimiento informado para responder un cuestionario sociodemográfico y de vida sexual, y permitir la toma de una muestra sanguínea. La presencia de anticuerpos contra el virus herpes simplex tipo 2 entre las mujeres se realizó por la técnica de "Western blot"específica para el virus herpes simplex tipo 2; las asociaciones entre estos resultados y los datos de la encuesta se analizaron estadísticamente, de manera cruda y ajustada. RESULTADOS: Las mujeres concáncer cervical tuvieron una seroprevalencia de infección por el virus herpes simplex tipo 2 de 46.8% (191/408; las de población general negativas al Papanicolaou de 29.3% (214/730, y aquellas con cáncer de mama de 22.6% (29/128. Las variables asociadas significativamente a la seropositividad contra este virus fueron la edad creciente, el aumento en el número de parejas sexuales, tener cáncer cervical, y entre las mujeres con esa patología, el inicio antes de los 21 años de edad de la actividad sexual y el estar divorciadas o separadas. CONCLUSIONES: Los hallazgos observados revelaron diferencias estadísticas en la seroprevalencia del virus herpes, de acuerdo con los grupos poblacionales estudiados. La frecuencia global de la infección viral entre las participantes las sitúa en un riesgo intermedio, en comparación con otros grupos poblacionales que en México son de alto y bajo riesgo (trabajadoras sexuales y estudiantes universitarias, respectivamente, analizados en años recientes.

    Full Text Available El parvovirus canino tipo 2 (VPC-2 es el agente causal de una enfermedad infecto-contagiosa que produce gastroenteritis aguda hemorrágica que afecta a caninos jóvenes. El VPC-2 es un virus con genoma ADN, pequeño, desnudo y muy resistente a las condiciones ambientales que emergió y se expandió rápidamente a fines de la década de los años 70. En los años 80 surgieron consecutivamente dos variantes antigénicas, denominadas VPC-2a y VPC-2b. En el 2000 se detectó una nueva variante antigénica llamada VPC-2c, reportándose con frecuencia en comunidades caninas de varios países del mundo. El objetivo de este trabajo consistió en caracterizar un aislamiento cubano de parvovirus canino, atenuado y adaptado a cultivo celular. El material genético fue amplificado por reacción en cadena de la polimerasa y secuenciado posteriormente. Las secuencias obtenidas fueron analizadas y comparadas con secuencias de aislados y cepas conocidas depositadas en las bases de datos, donde se evidenció que el aislamiento cubano era del tipo VPC-2.

    Full Text Available In questo studio si riporta un caso di coinfezione da parvovirus canino (CPV di tipo 2a e da virus della panleucopenia felina (FPV in un gatto di 3 mesi, con la presenza di una variante di parvovirus avente caratteristiche genetiche intermedie tra CPV e FPV. Il riscontro di una variante virale caratterizzata da epitopi specifici sia per il FPV che per il CPV avvalora l'importanza del meccanismo evolutivo per mutazioni multistep nella produzione di nuove varianti e nell'emergenza di nuovi virus. Questo tipo di adattamento progressivo è già stato riscontrato durante l'emergenza del CPV. Sulla base dei risultati ottenuti, è possibile ipotizzare che il CPV abbia presumibilmente iniziato un nuovo processo di riadattamento nell'ospite felino, confermando l'importanza del salto d'ospite nell'emergenza di nuovi virus.

    Full Text Available Descrevem-se os achados clínicos e patológicos e os exames laboratoriais de filhotes de cães com diagnóstico post mortem de infecção por herpesvírus canino. Os casos ocorreram em duas propriedades da Cidade de Porto Alegre, Rio Grande do Sul, em abril de 2007 e julho de 2008. Clinicamente, os cães apresentaram anorexia, apatia, choro e dispneia. A morte dos cães ocorreu após 24-72 horas do início dos sinais clínicos. Na necropsia observaram-se hemorragia multifocal renal e hepatomegalia com petéquias e pontos brancos na superfície natural do fígado. Os pulmões se apresentaram não-colapsados e vermelhos. Havia esplenomegalia e, em alguns cães, petéquias na superfície capsular do baço. Aumento dos linfonodos mesentéricos e do timo foi observado. Lesões microscópicas incluíram hemorragia e necrose multifocal em células epiteliais tubulares renais, hepatócitos e tecidos linfoides. Nos pulmões, havia necrose alveolar multifocal acentuada com abundante material fibrinoso e infiltrado inflamatório misto de intensidade variada. Ocasionais corpúsculos de inclusão intranucleares em áreas periféricas à necrose foram identificados em hepatócitos, células epiteliais de túbulos renais e células alveolares. Amostras de fígado, rim e pulmão foram positivas na imunofluorescência direta para herpesvírus canino tipo 1 (CHV-1. O diagnóstico de infecção por herpesvírus foi baseado nos achados de necropsia, histológicos e de imunofluorescência positiva em tecidos usando anticorpo anti-CHV-1. De nosso conhecimento, este é o primeiro relato da identificação do CHV-1 no Brasil, embora achados clínico-patológicos anteriores já sugerissem a presença do agente na população canina do país.The clinic and pathological findings and laboratorial testing of puppies with postmortem diagnosis of canine herpesvirus infection are described. The cases occurred in two households of Porto Alegre, RS, in April 2007 and July 2008

    Full Text Available OBJETIVO: Testar a presença de DNA de Citomegalovírus Humano (HCMV e Herpesvírus Simples tipo 2 (HSV-2 em amostras cervicais de mulheres atendidas em um serviço de atenção primária à saúde no município de Coari, Amazonas, Brasil. MÉTODOS: Participaram deste estudo 361 mulheres sexualmente ativas, variando entre 18 e 78 anos, atendidas em Unidades Básicas de Saúde para exame ginecológico de rotina. As amostras cervicais foram coletadas por meio de escova endocervical. A detecção dos vírus deu-se por meio de Reação em Cadeia da Polimerase (PCR em tempo real. RESULTADOS: A média de idade das mulheres participantes foi de 36,4 anos (desvio-padrão (DP=13,4. Foi encontrado DNA de HCMV em amostras cervicais de 30 mulheres (8,3%; IC95% 5,8 - 11,8 e de HSV-2 em 2 mulheres (0,6%; IC95% 0,1 - 2,2. Duas mulheres relataram ser portadoras do HIV, estando uma delas infectada com o HCMV. Não foram encontradas associações estatisticamente significativas entre a infecção pelos patógenos estudados e as variáveis socioeconômicas, clínicas e comportamentais. CONCLUSÕES: A prevalência de infecção pelo HCMV encontrada na amostra estudada chama a atenção para a necessidade do rastreio desse vírus na gestação e da vigilância nos pacientes imunocomprometidos. A baixa prevalência do HSV-2 deve-se provavelmente ao fato de a amostra cervical não ser adequada para este tipo de estudo por causa das características da biologia viral relacionadas à neurolatência.PURPOSE: To detect the presence of Human Cytomegalovirus (HCMV and Herpes Simplex Virus type 2 (HSV-2 DNA in cervical samples from women assisted in a primary health care clinic in the city of Coari, Amazonas, Brazil.

    Full Text Available O Parvovírus Canino (CPV é um patógeno emergente em cães, isolado pela primeira vez em 1978, nos Estados Unidos. A amostra original de 1978 foi designada CPV tipo 2 (CPV-2. Entretanto, análises de isolados de CPV dos Estados Unidos, por enzimas de restrição e anticorpos monoclonais demonstraram que cerca de 1979, uma amostra variante, designada CPV tipo 2a (CPV-2a tornou-se prevalente. Subseqüentemente, uma nova amostra antigênica, designada CPV tipo 2b (CPV-2b também foi observada por análises de isolados de CPV de várias partes do mundo, embora a proporção fosse diferente entre os países. Nesse estudo, foi utilizado o teste de Inibição da Hemaglutinação (HI com um painel de anticorpos monoclonais para a tipagem de 29 amostras fecais de parvovirus canino, coletadas de cães sintomáticos de 1980 a 1986 e de 1990 a 1995. Os resultados indicaram uma forte predominância do tipo antigênico 2a indicando que a epizootia de CPV no Brasil seguiu o mesmo padrão observados na Europa e países Asiáticos.

Cuando estos tumores se presentan en machos por lo general tienen características histológicas malignas. Para el diagnóstico histopatológico la clasificación que ha tenido mayor aceptación es la propuesta por Hampe and Misdorp. A través de muchos años de investigación en este campo se han descrito varios factores considerados como predisponentes, entre los cuales están: raza, sexo, edad, dentro de estos la que presenta mayor disparidad de conceptos es la raza ya que, según algunos autores, se puede ver influenciada por factores externos como la localización geográfica y el gusto de los propietarios por ciertas razas como animales de compañía. Otro hecho importante es la descripción de agentes causales: el invalance hormonal (estrógenos, progesterona, mutaciones genéticas, (gen supresor del tumor, protooncogenes y consumo de dietas ricas en grasas. Finalmente, es importante hacer énfasis en el hecho que del diagnóstico adecuado y pautas de tratamiento llevados a cabo por el médico veterinario clínico, depende el pronóstico y las expectativas de vida del paciente canino.

    Science.gov (United States)

    Leung, Alexander K C; Robson, W Lane M; Leong, Alexander G

    2006-01-01

    Herpes zoster is caused by reactivation of latent varicella-zoster virus that resides in a dorsal root ganglion. Herpes zoster can develop any time after a primary infection. Because varicella vaccine is a live attenuated virus, herpes zoster can develop in a vaccine recipient. The incidence of herpes zoster among vaccine recipients is about 14 cases per 100,000 person-years. In young children, herpes zoster has a predilection for areas supplied by the cervical and sacral dermatomes. The most common complications are secondary bacterial infection, depigmentation, and scarring. Although the diagnosis of herpes zoster is based on a distinct clinical appearance, viral DNA analysis of the lesion by polymerase chain reaction or restriction fragment length polymorphism is necessary to differentiate wild from vaccine-type viruses. Acyclovir is the treatment of choice for herpes zoster.

    Full Text Available History of present illness: A 26-year-old male presented to the emergency department with a burning rash over his left axilla and chest that started 2 days prior to presentation. The pain had been steadily worsening and was exacerbated by touch and the rubbing of his clothes over it. Patient denied fevers, chills, or weakness. Patient denied any past medical history, past surgical history or medications. He was unsure of his vaccination history and endorsed having chicken pox as a child. Significant findings: The patient was in mild distress, afebrile, with stable vital signs. His physical exam revealed an erythematous, grouped vesicular rash in various stages of progression including erythematous papules, clear vesicles, and pustular vesicles. Few lesions were scabbed over. No signs of crusting or scarring were appreciated. The distribution encompassed the entire left T4 dermatome both posteriorly and anteriorly. No other rashes were appreciated elsewhere on the body. Discussion: Herpes Zoster (HZ, also known as “shingles,” is a result of the reactivation Varicella Zoster Virus (VZV that emerges from latency in the sensory dorsal root ganglion. The reactivation causes the spreading of a classic rash of group vesicular lesions in various stages along the unilateral sensory dermatomal distribution over the first 3 days. Ulceration and crusting begin to occur after 3-5 days.1 The diagnosis is usually made clinically; however PCR testing of skin lesions is also available to differentiate between VZV, HSV1, and HSV2.2 The incidence of HZ increases with age due to immunosenesacence of cell mediated immunity, with the mean age between 43 and 53 years old.3 An immunocompromised state, due to factors like human immunodeficiency virus (HIV, medications, and autoimmune disease, also increases the incidence of HZ.4-6 A routine HIV screening in this patient was negative. He was prescribed oral acyclovir 800 mg, five times per day for five days.

Foram utilizados 30 cães neonatos de ambos os sexos, sem raça definida, aos três, 10, 17, 24, 31, 38 e 45 dias de idade. A contagem de leucócitos totais aos 45 dias (11.639±3.574 foi significativamente maior que no terceiro dia de idade (8.740±1.812 (P<0,05; não houve diferença entre a contagem total de linfócitos aos 45 dias em relação ao terceiro dia de idade. Quanto às subpopulações de LT CD4+ e LT CD8+, os percentuais de LT CD4+, aos três dias de idade (24,9±16,8%, foram inferiores quando comparados à média entre o 10°, o 24° e o 31°dia (35,5%, e os de CD8+, ao terceiro dia, menores em relação às médias do 10° e do 31° dia de idade. Pode-se concluir que as subpopulações de LT CD4+ e CD8+ sofrem oscilações durante o desenvolvimento pós-natal, sendo estas crescentes em relação aos níveis obtidos aos três dias de idade. A relação CD4+:CD8+ mostrou superioridade para o primeiro tipo celular, sendo que a maior relação entre CD4+ e CD8+ ocorreu no terceiro dia de idade. Com base nos resultados obtidos neste estudo, notaram-se as diferenças semanais nas populações linfocitárias, o que demonstra a dinâmica dessas células durante o período neonatal.

    Early institution of therapy with acyclovir is essential for the successful outcome in herpes simplex encephalitis. Brain biopsy remains the only conclusive means of establishing the diagnosis, but many fear possible biobsy complications. Thus, therapy is often instituted when the diagnosis is clinically suspected, even though cerebral computed tomography and other diagnostic studies may be inconclusive. Nuclear magnetic resonance imaging (NMR) has proven to be a sensitive tool for diagnosing presumptive herpes simplex encephalitis. This case presentation demonstrates the superiority of cerebral NMR over computerized tomography for detecting early temporal lobe changes consistent with acute herpes simplex encephalitis

El hecho de que determinadas unidades estructurales, en evidente relación con los espacios sub-aracnoideos, hayan sido preferentemente comprometidas, en contraste con otras que se han mantenido indemnes por estar fuera de la influencia de aquellos y de su liquor circulante, hace sospechar que aparte de la vía sanguínea, sea el liquor uno de los vehículos del agente infectante. Pero lo que esta influencia no explica es el cambio parcial de las células nerviosas de ciertas zonas, de las formaciones ammónicas, Fig. Nº 44, ni la alteración de los componentes celulares de una unidad arquitectural, de lámina Vª de la corteza, por ejemplo. Para esta especie de variación no cabe al presente, mas que la sospecha, a menudo comprobada, de que determinadas unidades celulares o arquitecturales, poseen cierto grado de vulnerabilidad bis a bis de los agentes agresores. Y esta opinión tan a menudo verificada en la patología humana no tiene porqué no ser extendida a los cambios en los tejidos nerviosos de animales inferiores. El asta de Ammón humana ha sido con frecuencia estudiada en múltiples procesos patológicos, comprobándose la manera fácil con que agentes vulnerantes la modifican y lesionan, pero, que sepamos, no se han hecho estudios detenidos de ella en procesos sospechosos virulentos como en las encefalitis, ni en aquellos debidos a bacterias.

    Genital herpes is a common sexually transmitted disease, affecting more than 400 million persons worldwide. It is caused by herpes simplex virus (HSV) and characterized by lifelong infection and periodic reactivation. A visible outbreak consists of single or clustered vesicles on the genitalia, perineum, buttocks, upper thighs, or perianal areas that ulcerate before resolving. Symptoms of primary infection may include malaise, fever, or localized adenopathy. Subsequent outbreaks, caused by reactivation of latent virus, are usually milder. Asymptomatic shedding of transmissible virus is common. Although HSV-1 and HSV-2 are indistinguishable visually, they exhibit differences in behavior that may affect management. Patients with HSV-2 have a higher risk of acquiring human immunodeficiency virus (HIV) infection. Polymerase chain reaction assay is the preferred method of confirming HSV infection in patients with active lesions. Treatment of primary and subsequent outbreaks with nucleoside analogues is well tolerated and reduces duration, severity, and frequency of recurrences. In patients with HSV who are HIV-negative, treatment reduces transmission of HSV to uninfected partners. During pregnancy, antiviral prophylaxis with acyclovir is recommended from 36 weeks of gestation until delivery in women with a history of genital herpes. Elective cesarean delivery should be performed in laboring patients with active lesions to reduce the risk of neonatal herpes.

    Herpes zoster optic neuropathy (HZON) is a rare manifestation of herpes zoster ophthalmicus (HZO). The aim of our study was to better characterize the clinical features, therapeutic choices, and visual outcomes in HZON. A retrospective chart review was performed at multiple academic eye centers with the inclusion criteria of all eyes presenting with optic neuropathy within 1 month of cutaneous zoster of the ipsilateral trigeminal dermatome. Data were collected regarding presenting features, treatment regimen, and visual acuity outcomes. Six patients meeting the HZON inclusion criteria were identified. Mean follow-up was 2.75 months (range 0.5-4 months). Herpes zoster optic neuropathy developed at a mean of 14.1 days after initial rash (range 6-30 days). Optic neuropathy was anterior in 2 eyes and retrobulbar in 4 eyes. Other manifestations of HZO included keratoconjunctivitis (3 eyes) and iritis (4 eyes). All patients were treated with systemic antiviral therapy in addition to topical and/or systemic corticosteroids. At the last follow-up, visual acuity in 3 eyes had improved relative to presentation, 2 eyes had worsened, and 1 eye remained the same. The 2 eyes that did not receive systemic corticosteroids had the best observed final visual acuity. Herpes zoster optic neuropathy is an unusual but distinctive complication of HZO. Visual recovery after HZON is variable. Identification of an optimal treatment regiment for HZON could not be identified from our patient cohort. Systemic antiviral agents are a component of HZON treatment regimens. Efficacy of systemic corticosteroids for HZON remains unclear and should be considered on a case-by-case basis.

    1979-09-01

    In recent years, a great increase in interest in genital herpes has been stimulated partly by the rising prevalence of this disease and partly by observations suggesting that genital herpes is a cause of cervical cancer. The clinical pictures produced by genital herpes simplex virus infections are similar in men and women. In contrast to recurrent attacks, initial episodes of infection are generally more extensive, last longer, and are more often associated with regional lymphadenopathy and systemic symptoms. Genital herpes in pregnancy may pose a serious threat to the newborn infant. Although the data suggesting genital herpes simplex virus infection is a cause of cervical cancer are quite extensive, the evidence is largely circumstantial. In spite of these more serious aspects of genital herpes simplex virus infection, episodes of genital herpes are almost always self-limited and benign. Frequent recurrences pose the major therapeutic and management problem. At present, there is no satisfactory treatment for recurrent genital herpes simplex virus in fection. Many of the suggested therapies, although some sound very promising, are potentially dangerous and should be used only under carefully controlled conditions.

    Full Text Available Extensive reviews of pulmonary infections in AIDS have reported few herpetic infections. Generally these infections are due to Herpes simplex type 1. Pneumonia due to herpes type 2 is extremely rare. We describe a 40 year-old HIV positive woman who complained of fever, cough and dyspnea for seven years. She had signs of heart failure and the appearance of her genital vesicles was highly suggestive of genital herpes. Echocardiography showed marked pulmonary hypertension, right ventricular hypertrophy and tricuspid insufficiency. After a few days of hospitalization she was treated with Aciclovir and later with Ganciclovir. An open pulmonary biopsy revealed an interstitial inflammation, localized in the alveolar walls. Some pulmonary arteries had widened walls and focal hyaline degeneration. Immunohistochemistry indicated that the nuclei had herpes simplex virus type 2 in many endothelial cells (including vessels with widened walls, macrophages in the alveolar septa and pneumocytes. There was clinical improvement after treatment for herpes. We concluded that as a consequence of herpes infection, endothelial involvement and interstitial inflammation supervene, with thickening of vascular walls and partial obliteration of the vessel lumen. A direct consequence of these changes in pulmonary vasculature was pulmonary hypertension followed by heart failure.

El análisis de componentes principales inicial reveló nueve factores con una variación explicada de 65,29%. Sin embargo, no se consideraron tres factores por contener cada uno de ellos solamente un reactivo. Por tanto, la escala final se acepta con 38 reactivos. El coeficiente de confiabilidad Alfa de Cronbach fue de, 93. Discusión: el análisis reveló seis factores, uno más de lo reportado por Roy, y con mayor variación explicada. Algunos reactivos parecen no ser bien comprendidos por los participantes. Conclusiones: este artículo aporta una aproximación metodológica para explorar la adecuación de un instrumento a una población diferente para la que originalmente fue diseñado. Se concluye que la escala tiene consistencia interna y validez de constructo incipiente, los datos reportados en este estudio deben tomarse en cuenta con cautela. Es conveniente revisar de nuevo los reactivos y adecuarlos a la cultura particular, y probar la escala de nuevo con pacientes con enfermedades crónicas degenerativas a fin de contar con instrumentos culturalmente equivalentes.

    Herpes zoster or shingles is reactivation of the varicella zoster virus that had entered the cutaneous nerve endings during an earlier episode of chicken pox traveled to the dorsal root ganglia and remained in a latent form. This condition is characterized by occurrence of multiple, painful, unilateral vesicles and ulceration which shows a typical single dermatome involvement. In this case report, we present a patient with herpes zoster involving the mandibular division of the trigeminal nerve, with unilateral vesicles over the right side of lower third of face along the trigeminal nerve tract, with intraoral involvement of buccal mucosa, labial mucosa and the tongue of the same side. Cytopathology revealed classic features of herpes infection including inclusion bodies, perinuclear halo and multinucleated cells.

    Full Text Available Herpes zoster is a common infection caused by the human herpes virus 3, the same virus that causes chickenpox. It is a member of herpes viridae, the same family as the herpes simplex virus, Epstein- Barr virus, and cytomegalovirus. Herpes zoster ophthalmicus occurs when a latent varicella zoster virus in the trigeminal ganglia involving the ophthalmic division of the nerve is reactivated. Of the three divisions of the fifth cranial nerve, the ophthalmic is involved 20 times more frequently than the other divisions.

    Full Text Available This study aimed the in vitro growth characterization of a previously constructed Brazilian bovine herpesvirus 1.2a with a deletion in the glycoprotein E gene (BHV-1.2a gE-. The plaque sizes, penetration and growth kinetics of the Brazilian BHV-1.2a gE- were studied and compared with the parental virus, as well as with a BHV-1.1 gE- recombinant derived from an European BHV-1.1 strain. No statistical differences were observed between the gE- recombinants and the respective parental viruses penetration assays were performed. When single step growth curves were studied, no statistical differences were observed between gE- and parental viruses. However, it was observed that both gE- viruses were excreted from cells in significantly higher titres at 11 hours post infection in comparison with parental viruses. No statistical differences were observed when plaque sizes of parental viruses or gE- viruses we analyzed separately in each cell type. However, both gE- recombinants displayed a significantly reduced plaque areas on three different cell cultures, in comparison with parental viruses, indicating that the lack of gE had the same effect on both BHV-1 subtypes, manifested by a restricted cell-to-cell spread in infected cells.O presente estudo teve como objetivo a caracterização das propriedades de crescimento in vitro de uma amostra brasileira de herpesvírus bovino tipo 1.2a que apresenta uma deleção no gene que codifica a glicoproteína E (BHV-1.2a gE-.

    Full Text Available The serpin maspin, a tumor suppressor in breast cancer was described as an inhibitor of cell migration and inducer of cell adhesion between the basement membrane and extracellular matrix resulting in inhibition of tumor metastasis. In contrast, overexpression of maspin is correlated with poor prognosis in other types of cancer. Little is known about expression, regulation and function of maspin in canine mammary tumors. It was demonstrated in this study, a loss of maspin expression in malignant canine mammary cells compared with a pool of normal canine mammary tissue, analyzed by quantitative real-time PCR; weak maspin expression in malignant canine mammary tumors were observed by immunohistochemistry. It was also demonstrated that a correlation with nuclear maspin expression and a good prognosis. It is suggested that maspin could be used as a prognostic marker in canine mammary neoplasia.O serpin maspin, um supressor tumoral no câncer de mama foi descrito como inibidor de migração celular e indutor de adesão celular entre a membrana basal e a matriz extracelular resultando na inibição da metástase tumoral. Por outro lado, a alta expressão do maspin está relacionada com um mau prognóstico em outros tipos de câncer. Pouco se sabe sobre a expressão, regulação e função do maspin nos tumores mamários caninos. Neste estudo, foi demonstrada uma perda da expressão de maspin nas células mamárias malignas de cães quando comparadas com um pool de tecido mamário normal de cães, analisado por PCR quantitativa em tempo real. Houve uma expressão fraca maspin em preparações de tumores mamários malignos observadas por imuno-histoquímica. Também foi verificado que a expressão nuclear do maspin em tumores mamários caninos está relacionada a um bom prognóstico.

    Genital herpes has a high global prevalence and burden of disease. This manuscript highlights recent advances in our understanding of genital herpes simplex virus (HSV) infections. Studies demonstrate a changing epidemiological landscape with an increasing proportion of genital herpes cases associated with HSV type 1. There is also growing evidence that the majority of infected individuals exhibit frequent, brief shedding episodes that are most often asymptomatic, which likely contribute to high HSV transmission rates. Given this finding as well as readily available serological assays, some have proposed that routine HSV screening be performed; however, this remains controversial and is not currently recommended. Host immune responses, particularly local CD4 and CD8 T cell activity, are crucial for HSV control and clearance following initial infection, during latency and after reactivation. Prior HSV immunity may also afford partial protection against HSV reinfection and disease. Although HSV vaccine trials have been disappointing to date and existing antiviral medications are limited, novel prophylactic and therapeutic modalities are currently in development. Although much remains unknown about genital herpes, improved knowledge of HSV epidemiology, pathogenesis and host immunity may help guide new strategies for disease prevention and control.

    2016-01-01

    As one of the most common sexually transmitted diseases, genital herpes is a global medical problem with significant physical and psychological morbidity. Genital herpes is caused by herpes simplex virus type 1 or type 2 and can manifest as primary and/or recurrent infection. This manuscript provides an overview about the fundamental knowledge on the virus, its epidemiology, and infection. Furthermore, the current possibilities of antiviral therapeutic interventions and laboratory diagnosis of genital herpes as well as the present situation and perspectives for the treatment by novel antivirals and prevention of disease by vaccination are presented. Since the medical management of patients with genital herpes simplex virus infection is often unsatisfactory, this review aims at all physicians and health professionals who are involved in the care of patients with genital herpes. The information provided would help to improve the counseling of affected patients and to optimize the diagnosis, treatment, and prevention of this particular disease.

    Herpes simplex virus infection following surgery is an unusual postoperative phenomenon. Many mechanisms have been suggested, with the most likely explanation related to latent virus reactivation due to a proinflammatory response in the setting of local trauma. Here, we present a case of herpes simplex virus reactivation in an immunocompetent female following a conventional right lower extremity stab phlebectomy. Salient clinical and physical examination findings are described, and management strategies for herpes simplex virus reactivation are outlined. This is the first known case report of herpes simplex virus reactivation following lower extremity phlebectomy.

    Full Text Available RESUMOObjetivou-se com este trabalho comparar o padrão de crescimento, mediante ajustes das respectivas curvas de crescimento por modelos não lineares, bem como estudar o desenvolvimento de cortes de carcaça em relação ao peso da carcaça em diferentes genótipos de frangos tipo caipira. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos da linhagem Redbro: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. As aves foram alojadas em 28 boxes, sendo 30 aves/boxe, em galpão de alvenaria com acesso a um piquete de 45m², com quatro repetições. O peso corporal individual dos frangos foi medido ao nascer, aos 14, 28, 42, 56, 70 e 84 dias de idade. Para a determinação das curvas de crescimento do peso corporal das aves, os dados coletados foram avaliados por meio dos modelos não lineares: Brody, Gompertz, Logístico, Richards e von Bertalanffy. Foi empregado o PROC NLIN do SAS, utilizando-se o método interativo de Gauss-Newton. Os critérios usados para escolha do modelo de melhor ajuste da curva de crescimento foram o coeficiente de determinação, o desvio padrão assintótico, o desvio médio absoluto dos resíduos e o índice assintótico. As análises para obtenção dos coeficientes alométricos foram realizadas por meio do PROC GLM do SAS para os genótipos Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor. Foram avaliados os pesos da carcaça, do peito, das coxas, das sobrecoxas, das pernas e das asas das aves abatidas aos 85 dias de idade. Apenas as equações propostas por Gompertz, von Bertalanffy e Logístico atingiram a convergência, e o modelo proposto por von Bertalanffy foi o mais adequado para descrever o crescimento dos genótipos de frangos caipiras. Todos os cortes avaliados apresentaram crescimento tardio em relação ao peso da carcaça em genótipos de frangos tipo caipira.

A vacinação é freqüentemente empregada para minimizar as perdas produzidas pela infecção. Todavia, a imunização de vacas durante a prenhez com algumas vacinas contendo vírus vivo modificado (MLV pode ocasionalmente causar abortos. Em trabalho prévio, nosso grupo desenvolveu uma vacina recombinante de BoHV-1 construída a partir de um isolado brasileiro de BoHV-1 (Franco et al., 2002a do qual o gene que codifica para a glicoproteína E (gE foi artificialmente deletado. Tal recombinante (gE- vem sendo avaliado como vacina diferencial, isto é, capaz de permitir a diferenciação entre animais vacinados e infectados. No presente estudo, o potencial de disseminação do vírus recombinante foi avaliado em um rebanho de gado de corte, em condições de campo. Para tanto, a segurança da vacina gE- quando aplicada durante a prenhez foi avaliada pela inoculação intramuscular de 10(7,4 doses infectantes para 50% dos cultivos celulares (DICC50 do vírus em 22 fêmeas prenhes (14 previamente soronegativas e 8 previamente soropositivas para BoHV-1 em diferentes fases da gestação. Outras 15 vacas prenhes foram mantidas como controles não-vacinados. Não ocorreram abortos, natimortos ou anormalidades fetais em nenhum dos grupos. Soroconversão foi observada nas fêmeas vacinadas previamente soronegativas. Em um segundo experimento, 4 novilhas foram inoculadas pela via intranasal com 10(7,6 DICC50 do vírus recombinante, sendo mantidos em contato com 16 novilhas em uma área de campo, a uma densidade de 1 animal por hectare.

Os cães podem atacar os sapos, entrando em contato com o veneno por meio das mucosas. Um canino, da raça Bulldog Francês, foi encaminhado ao Setor de Patologia Veterinária da Universidade Federal do Rio Grande do Sul (UFRGS para a necropsia com histórico de provável intoxicação por veneno de sapo. Na necropsia o canino apresentava pulmões aumentados de volume, avermelhados e com edema, e rins de coloração vermelho-escura. As alterações microscópicas indicaram congestão, hemorragia e edema pulmonar. Nos rins, no baço e nos linfonodos foi observada congestão. As análises toxicológicas para os venenos de rotina foram negativas. Porém, a investigação do veneno de sapo a partir de cromatografia por camada delgada e gasosa demonstrou resultado positivo, revelando ser esta a causa da morte do canino.The toads of the genus Bufo produce, in their parotoid glands, a mucoid secretion containing toxins such as bufagins and Bufotoxins, which are cardiogenic steroids. The mucous membranes of dogs can absorb this venom when they attack the toads. A French bulldog with a history of probable toad venom intoxication was referred to Veterinary Pathology Section of Federal University of Rio Grande do Sul (UFRGS for necropsy. The necropsy revealed enlarged, reddish, edematous lungs, and kidneys displaying a dark red color. The microscopic alterations indicated the presence of congestion, hemorrhage, and pulmonary edema. Congestion was observed in the kidneys, spleen and lymph nodes. The routine toxicological analyses for venom detection were negative. Nevertheless, the toad venom test result was positive as assessed by thin layer and gas chromatography, indicating that toad venom intoxication was the cause of death.

    Herpes simplex virus (HSV) 1 and HSV-2 infections are highly prevalent worldwide and are characterized by establishing lifelong infection with periods of latency interspersed with periodic episodes of reactivation. Acquisition of HSV by an infant during the peripartum or postpartum period results in neonatal HSV disease, a rare but significant infection that can be associated with severe morbidity and mortality, especially if there is dissemination or central nervous system involvement. Diagnostic and therapeutic advances have led to improvements in mortality and, to a lesser extent, neurodevelopmental outcomes, but room exists for further improvement. Copyright © 2015 Elsevier Inc.

    Neonatal herpes simplex virus (HSV) is an uncommon but devastating infection in the newborn, associated with significant morbidity and mortality. The use of PCR for identification of infected infants and acyclovir for treatment has significantly improved the prognosis for affected infants. The subsequent use of suppressive therapy with oral acyclovir following completion of parenteral treatment of acute disease has further enhanced the long-term prognosis for these infants. This review article will discuss the epidemiology, risk factors and routes of acquisition, clinical presentation, and evaluation of an infant suspected to have the infection, and treatment of proven neonatal HSV disease.

    2012-10-01

    Genital herpes is a common sexually transmitted infection. In reproductive age it involves the additional risk of vertical transmission to the neonate. Rates of transmission are affected by the viral type and whether the infection around delivery is primary or recurrent. Neonatal herpes is a rare but very severe complication of genital herpes infection and is caused by contact with infected genital secretions at the time of labor. Maternal acquisition of herpes simplex virus (HSV) in the third trimester of pregnancy carries the highest risk of neonatal transmission. Prevention of neonatal herpes depends on preventing acquisition of genital HSV infection during late pregnancy and avoiding exposure of the infant to herpetic lesions during delivery. Uninfected woman should be counselled about the need of avoiding sexual contact during the third trimester. Elective caesarean section before the onset of labor is the choice mode of delivery for women with genital lesions or with prodromal symptoms near the term, even if it offers only a partial protection against neonatal infection. Antiviral suppressive therapy is used from 36 weeks of gestation until delivery in pregnant women with recurrences to prevent genital lesions at the time of labor so reducing the need of caesarean sections. Currently, routine maternal serologic screening is not yet recommended. Because most mothers of infants who acquire neonatal herpes lack histories of clinically evident genital herpes, researchers should focus on the recognition of asymptomatic primary genital HSV infections.

    With the decline in prevalence of childhood-acquired oral-labial herpes simplex type 1 infections in some populations and the increasing incidence of genital herpes infections in adults, clinicians are more likely to see patients with severe primary, first-episode genital herpes infections. Complications of these primary infections may include aseptic meningitis and urine retention secondary to sacral radiculopathy or autonomic dysfunction. Presented are the clinical course of first-episode and recurrent infections, complications, diagnostic laboratory methods, and results of controlled clinical trials evaluating the efficacy of topical, intravenous, and oral preparations of acyclovir.

    Herpes zoster infection particularly involving the sacral dermatomes has been associated with bladder and bowel dysfunction, most commonly urinary retention. We report two patients who developed acute urinary retention, one of whom also had constipation, within days of herpes zoster skin lesions of the S2-S4 dermatomes. Herpes zoster is a reversible cause of neurogenic bladder and bowel dysfunction and should be considered in a patient that presents with acute urinary retention and/or constipation. Sensory abnormalities and flaccid detrusor paralysis are most likely involved in the pathogenesis.

    Full Text Available Las dermatitis bacterianas o piodermas en caninos son ocasionadas por microorganismos patógenos, de los cuales el Staphylococcus intermedius es el más frecuente. Los tratamientos empíricos de este grupo de enfermedades permiten la proliferación de cepas resistentes de importancia en salud pública como es el caso del S. aureus. De igual forma, el riesgo de zoonosis reversa a partir de mascotas portadoras de cepas resistentes crea un serio problema de salud pública que requiere vigilancia epidemiológica. El objetivo de la investigación fue aislar e identificar bioquímicamente los microorganismos presentes en infecciones de piel en caninos; para esto se obtuvieron las muestras de caninos con problemas dermatológicos, y se identificaron los microorganismos bacterianos involucrados utilizando el kit de identificación rápida BBL Crystal para grampositivos. Los resultados obtenidos demostraron que el 80% de los aislamientos correspondieron a S. intermedius. Sin embargo, es necesario realizar estudios moleculares para relacionar la severidad de las lesiones dermatológicas con la identificación de los estafilococos presentes en el pioderma, y así establecer medidas de control, tratamiento y profilaxis.

    Genital herpes is an incurable, chronic disease that affects millions of people worldwide. Not only does genital herpes cause painful, recurrent symptoms, it is also a significant risk factor for the acquisition of other sexually transmitted infections such as HIV-1. Antiviral drugs are used to treat herpes simplex virus (HSV) infection, but they cannot stop viral shedding and transmission. Thus, developing a vaccine that can prevent or clear infection will be crucial in limiting the spread of disease. In this review we outline recent studies that improve our understanding of host responses against HSV infection, discuss past clinical vaccine trials, and highlight new strategies for vaccine design against genital herpes.

    Varicella- zoster virus infection is an intriguing medical entity that involves many medical specialties including infectious diseases, immunology, dermatology, and neurology. It can affect patients from early childhood to old age. Its treatment requires expertise in pain management and psychological support. While varicella is caused by acute viremia, herpes zoster occurs after the dormant viral infection, involving the cranial nerve or sensory root ganglia, is re-activated and spreads orthodromically from the ganglion, via the sensory nerve root, to the innervated target tissue (skin, cornea, auditory canal, etc.). Typically, a single dermatome is involved, although two or three adjacent dermatomes may be affected. The lesions usually do not cross the midline. Herpes zoster can also present with unique or atypical clinical manifestations, such as glioma, zoster sine herpete and bilateral herpes zoster, which can be a challenging diagnosis even for experienced physicians. We discuss the epidemiology, pathophysiology, diagnosis and management of Herpes Zoster, typical and atypical presentations.

    Herpes genitalis is caused by the herpes simplex virus type 1 or type 2 and can manifest as primary or recurrent infection. It is one of the most common sexually transmitted infections and due to associated physical and psychological morbidity it constitutes a considerable, often underestimated medical problem. In addition to providing the reader with basic knowledge of the pathogen and clinical presentation of herpes genitalis, this review article discusses important aspects of the laboratory diagnostics, antiviral therapy and prophylaxis. The article is aimed at all health-care workers managing patients with herpes genitalis and attempts to improve the often suboptimal counselling, targeted use of laboratory diagnostics, treatment and preventive measures provided to patients.

    Full Text Available Herpes zoster is an acute dermatomal viral infection caused by the reactivation of varicella zoster virus. The disease is commonly seen among elderly people and immunocompromised individuals, it is also rarely observed in immunocompetent children though. In this report, two herpes zoster cases with trigeminal-involvement in which no factors inducing the reactivation of the virus were detected are presented, as the disease is unusually seen during childhood.

    Urinary retention is uncommon in patients with herpes zoster and anogenital herpes simplex. Seven patients (four men, three women) with a mean age of 68.1 years (range, 35-84) with urinary retention due to herpes zoster (n = 6) or anogenital herpes simplex (n = 1) were studied. Six patients had unilateral skin eruption in the saddle area (S2-4 dermatome) and one patient with herpes zoster had a skin lesion in the L4-5 dermatome. All patients had detrusor areflexia without bladder sensation, and two of them had inactive external sphincter on electromyography at presentation. Clean intermittent catheterization was performed, and voiding function was recovered in 4-6 weeks (average, 5.4) in all patients. Urodynamic study was repeated after recovery of micturition in three patients, and they returned to normal on cystometrography and external sphincter electromyography. Acute urinary retention associated with anogenital herpes infection has been thought to occur when the meninges or sacral spinal ganglia were involved, and, in conclusion, this condition may be considered to be reversible.

    Full Text Available During 1983-86, 225 patients were clinically diagnosed to have genital herpes (GH at our clinic. Of these, 90 men and 55 women were currently married. All the spouses were screened clinically and through standardized techniques for isolation and typing of herpes simplex virus, serological testing and Papanicolaou smear. There were 90 couples in whom at least one spouse had GH and in 38 (42% couples both partners had GH. Clinically, 49% of wives and 75% of husbands of GH patients were diagnosed to have the disease. The spouses of recurrent GH patients had a higher frequency of the disease than spouses of primary GH patients. Among spouses who were clinically asymptomatic, 40% had high serological titres suggestive of GH. Wives generally experienced more severe symptoms, especially pain in the lesions. Majority of lesions in both the partners were vesicles and ulcers. Prodromata were more among recurrent GH patients in both the partners. The frequency of recurrences wasalso similar in spouses. Seventy percent of wives and 40% of husbands could not identify any precipitating factor. Intercourse, physical stress and rich food were cited as possible factors in the remaining. All the wives had acquired the diseases through their husbands who were promiscuous. Fifty percent of husbands had been infected before marriage. Given the fact that asymptomatic carriers exist, it is better to consider all marital partners of GH as infected. Repeated and long-term follow, - up examination, particularly of wives of GH patients is therefore essential as an important socio-preventive aspect of this disease.

Real time-polymerase chain reaction analyses were positive for both herpes simplex virus (HSV) type 1 and varicella zoster virus (VZV......). The most probable explanation is that this reflects asymptomatic, latent expression of HSV-1 in a herpes zoster patient with no clinical relevance.

    Because guanine-based herpes simplex virus thymidine kinase inhibitors are not orally available, we synthesized various 6-deoxy prodrugs of these compounds and evaluated them with regard to solubility in water, oral bioavailability, and efficacy to prevent herpes simplex virus-1 reactivation from latency in a mouse model. Organic synthesis was used to prepare compounds, High Performance Liquid Chromatography (HPLC) to analyze hydrolytic conversion, Mass Spectrometry (MS) to measure oral bioavailability, and mouse latent infection and induced reactivation to evaluate the efficacy of a specific prodrug. Aqueous solubilities of prodrugs were improved, oxidation of prodrugs by animal cytosols occurred in vitro, and oral absorption of the optimal prodrug sacrovir™ (6-deoxy-mCF3PG) in the presence of the aqueous adjuvant Soluplus® and conversion to active compound N(2)-[3-(trifluoromethyl)pheny])guanine (mCF3PG) were accomplished in mice. Treatment of herpes simplex virus-1 latent mice with sacrovir™ in 1% Soluplus in drinking water significantly suppressed herpes simplex virus-1 reactivation and viral genomic replication. Ad libitum oral delivery of sacrovir™ was effective in suppressing herpes simplex virus-1 reactivation in ocularly infected latent mice as measured by the numbers of mice shedding infectious virus at the ocular surface, numbers of trigeminal ganglia positive for infectious virus, number of corneas that had detectable infectious virus, and herpes simplex virus-1 genome copy numbers in trigeminal ganglia following reactivation. These results demonstrate the statistically significant effect of the prodrug on suppressing herpes simplex virus-1 reactivation in vivo. © The Author(s) 2015.

    Herpes simplex virus is a common cause of ulcerative esophagitis in the immunocompromised or debilitated host. Despite a high prevalence of primary and recurrent Herpes simplex virus infection in the general population, Herpes simplex virus esophagitis (HSVE) appears to be rare in the immunocompetent host. We report three cases of endoscopically-diagnosed HSVE in apparently immunocompetent children; the presentation was characterized by acute onset of fever, odynophagia, and dysphagia. In two cases, the diagnosis was confirmed histologically by identification of herpes viral inclusions and culture of the virus in the presence of inflammation. The third case was considered to have probable HSVE based on the presence of typical cold sore on his lip, typical endoscopic finding, histopathological evidence of inflammation in esophageal biopsies and positive serologic evidence of acute Herpes simplex virus infection. Two cases received an intravenous course of acyclovir and one had self-limited recovery. All three cases had normal immunological workup and excellent health on long-term follow-up.

  20. Designing herpes viruses as oncolytics

    Directory of Open Access Journals (Sweden)

    Cole Peters

    Full Text Available Oncolytic herpes simplex virus (oHSV was one of the first genetically-engineered oncolytic viruses. Because HSV is a natural human pathogen that can cause serious disease, it is incumbent that it can be genetically-engineered or significantly attenuated for safety. Here, we present a detailed explanation of the functions of HSV-1 genes frequently mutated to endow oncolytic activity. These genes are nonessential for growth in tissue culture cells but are important for growth in postmitotic cells, interfering with intrinsic antiviral and innate immune responses or causing pathology, functions dispensable for replication in cancer cells. Understanding the function of these genes leads to informed creation of new oHSVs with better therapeutic efficacy. Virus infection and replication can also be directed to cancer cells through tumor-selective receptor binding and transcriptional- or post-transcriptional miRNA-targeting, respectively. In addition to the direct effects of oHSV on infected cancer cells and tumors, oHSV can be “armed” with transgenes that are: reporters, to track virus replication and spread; cytotoxic, to kill uninfected tumor cells; immune modulatory, to stimulate antitumor immunity; or tumor microenvironment altering, to enhance virus spread or to inhibit tumor growth. In addition to HSV-1, other alphaherpesviruses are also discussed for their oncolytic activity.

Desde un punto de vista funcional, los caninos son considerados dientes claves en la oclusión. Con un gran protagonismo estético, dan armonía al frente anterior y la línea de la sonrisa. La erupción de los caninos superiores debe ser observada con frecuencia ya que es el diente en segundo lugar que presenta alteraciones en su erupción después de los terceros molares, este seguimiento se debe realizar con observaciones clínicas como radiográficas para tener la posibilidad de ir guiando el trayecto de erupción. Desde los 8 a 10 años de edad empieza a palparse la prominencia del canino en el fondo del vestíbulo. Si no se palpa a los 10 años, está indicado realizar un estudio radiológico para valorar la posición y reabsorción radicular del canino temporal. En este trabajo se realizó un estudio descriptivo en radiografías panorámicas en niños con 10 años de edad de ambos sexos de la ciudad de Quito, con el objetivo de analizar los corredores de erupción de caninos superiores, así como observar e interpretar la situación de los caninos superiores y su relación con las estructuras vecinas, describir las curvas y columnas de erupción en caninos superiores, para determinar si existe alteraciones y diferencias en cuanto a la erupción de los caninos definitivos en relación al sexo de los niños evaluados.

    Full Text Available INTRODUÇÃO: a retração rápida de caninos por distração do ligamento periodontal é uma técnica de movimentação dentária que permite o fechamento de espaço da extração de primeiros pré-molares em um intervalo de 2 ou 3 semanas, proporcionando uma redução significativa no tempo do tratamento ortodôntico. A técnica cirúrgica para realização deste procedimento é relativamente simples, entretanto, nos casos onde o seio maxilar apresenta-se próximo ao ápice radicular de caninos e pré-molares, sempre há o risco de perfuração da membrana desta cavidade. OBJETIVO: o objetivo deste artigo é apresentar, através de um caso clínico, uma modificação na técnica original proposta por Liou e Huang, onde o levantamento do seio maxilar, executado de forma bastante simples, imprimiu maior controle e segurança ao ato cirúrgico necessário para a realização da retração rápida de caninos. CONCLUSÃO: a retração rápida de caninos é um procedimento exeqüível e o levantamento de seio maxilar pode auxiliar na execução do movimento dentário.INTRODUCTION: Rapid canine distalization using distraction of the periodontal ligament is a tooth movement technique that allows to close the space of extraction of first premolars in about 2 or 3 weeks, reducing orthodontic treatment time considerably. The surgical technique for this procedure is reasonably simple, however, during surgery in the maxilla, always exists the risk of sinus injury when the sinus membrane is close to the apex of canines and first premolars. AIM: The aim of this study is to present a case report showing a modification of the original technique proposed by Liou and Huang, where the maxillary sinus membrane lifting procedure was undertaken in a simple way, leaving it intact, and permitting a safer and more controlled protocol to start the rapid canine retraction.

    Genital herpes simplex virus (HSV) infections are very common worldwide. Approximately 22% of pregnant women are infected genitally with HSV, and most of them are unaware of this. The most devastating consequence of maternal genital herpes is HSV disease in the newborn. Although neonatal HSV infections remain uncommon, due to the significant morbidity and mortality associated with the infection, HSV infection in the newborn is often considered in the differential diagnosis of ill neonates. This review summarizes the epidemiology and management of neonatal HSV infections and discusses strategies to prevent HSV infection in the newborn. Copyright © 2014 Elsevier Inc.

    Eight patients with herpes simplex encephalitis among the 10 cases diagnosed at the University of Kansas Medical Center from 1966 to 1976 were studied with /sup 99m/Tc early in their diagnostic work-up. The images were unilaterally positive in the temporal lobe area in all 8 patients. Radionuclide studies can suggest herpes simplex as the specific etiology in cases of encephalitis and can also indicate the best site for brain biopsy to confirm the diagnosis by fluorescent antibody techniques. Appropriate antiviral therapy should be instituted as soon as possible to alter the course of this destructive form of viral encephalitis

    Active infection with herpes zoster may cause acute urinary retention, especially when it involves sacral dermatomes. Although frank retention usually develops days to weeks after eruption of the typical rash, bladder incompetence infrequently develops first, raising concern over other, more ominous etiologies. In the case presented, rash appearance was delayed until six weeks after the initial onset of urinary retention, a much longer interval than previously reported. Occult herpes zoster infection should be considered in patients presenting with an acute neurogenic bladder of obscure cause.

    Full Text Available La parvovirosis canina es una de las principales infecciones que provoca gastroenteritis, fundamentalmente en cachorros, con altos índices de morbiletalidad. Los diagnosticadores más utilizados se basan en la detección de partículas virales excretadas durante la fase aguda de la enfermedad. Algunos requieren equipos especializados, lo que aumenta los costos y el tiempo de diagnóstico. Por esto, la simplificación de estos métodos con alta sensibilidad y especificidad es prioritaria. En Cuba solo se logra un diagnóstico presuntivo sin la completa confirmación de la enfermedad, principalmente por la escasez o ausencia de un medio diagnóstico en toda la red de consultorios y clínicas veterinarias, rápido, eficaz y ajustable a nuestras condiciones. Este trabajo tuvo como objetivo obtener anticuerpos policlonales IgY a partir de yema de huevo de gallina y evaluarlos mediante un sistema de látex-aglutinación, para su posible uso como terapia y principalmente en el diagnóstico. Se inmunizaron por vía intramuscular dos gallinas de raza Leghorn con una cepa atenuada de parvovirus canino (PVC tipo 2. Se aplicaron 8 inoculaciones por ave cada 15 días. Se cosecharon los huevos y se purificaron los anticuerpos por el método de sulfato de dextrana/sulfato de sodio. Se determinó el título de IgY anti-PVC por el método de Inhibición de la Hemoaglutinación (IH y con antígeno de PVC acoplado a partículas de látex de poliestireno. Por IH se obtuvo un título de IgY anti-PVC de 1:1024. Las mezclas de anticuerpos con títulos alto y medio de ambas gallinas aglutinaron con los reactivos preparados con 230 y 460 µg/mL de antígeno. La mayor intensidad de la reacción y la mejor detectabilidad correspondieron a los reactivos elaborados con los anticuerpos de mayor título.

    Herein, we describe a patient with lesions of cutaneous herpes simplex virus 1 (HSV-1) infection over the knuckles of both hands in the context of an outbreak among boxers. Interestingly, the infection had an unusually long duration (4 weeks), and was not acquired directly through skin-to-skin contact, as it usually does among athletes (herpes gladiatorum). In our case, transmission was acquired through the use of shared boxing gloves contaminated by HSV-1. To the best of our knowledge, herpes gladiatorum, or wrestler's herpes, has not been described previously in boxers and infection over the knuckles is not commonly reported. © 2011 The Authors.

    Herpes zoster is a major health burden that can affect individuals of any age. It is seen more commonly among individuals aged ≥50 years, those with immunocompromised status, and those on immunosuppressant drugs. It is caused by a reactivation of varicella zoster virus infection. Cell-mediated immunity plays a role in this reactivation. Fever, pain, and itch are common symptoms before the onset of rash. Post-herpetic neuralgia is the most common complication associated with herpes zoster. Risk factors and complications associated with herpes zoster depend on the age, immune status, and the time of initializing treatment. Routine vaccination for individuals over 60 years has shown considerable effect in terms of reducing the incidence of herpes zoster and post-herpetic neuralgia. Treatment with antiviral drugs and analgesics within 72 hours of rash onset has been shown to reduce severity and complications associated with herpes zoster and post-herpetic neuralgia. This study mainly focuses on herpes zoster using articles and reviews from PubMed, Embase, Cochrane library, and a manual search from Google Scholar. We cover the incidence of herpes zoster, gender distribution, seasonal and regional distribution of herpes zoster, incidence of herpes zoster among immunocompromised individuals, incidence of post-herpetic neuralgia following a zoster infection, complications, management, and prevention of herpes zoster and post-herpetic neuralgia.

    Tattooing is a procedure where ink is applied to an area of the skin, mostly intraepidermally (1). This procedure is carried out mainly for aesthetic purposes. Lately, it has been used as a corrective medical procedure following amputation of mammilla. The procedure is aggressive (2), and the fact that skin is punctured many times with the same needle which cannot be fully sterilized may cause infection of the treated area with bacterial, fungal, or viral agents that may lead to health consequences manifesting in the form of verrucae vulgaris, molluscum contagiosum, and herpes simplex. On the other hand, complications such as granulomas, allergic reactions, Koebner phenomenon, lupus erythematosus, psoriasis, lichen ruber planus, hepatitis C, and HIV infections should also be considered as potential consequences of tattooing (3-7). Even systemic reactions have been reported. Herein we describe a case of herpes infection activation after tattooing. Herein we present the case of a 46-year-old woman, employed in the medical sector, with a two-day history of herpes simplex in the labial area that manifested following application of a cosmetic tattoo meant to outline the lips (Figure 1). Two days after tattoo application, the vesicular lesions appeared along the area that was filled with ink, followed by sub-febrile temperature and fever and a subjective feeling of itching initially, followed by burning sensation and pain. The skin signs located on erythematous base were mainly grouped vesicles with sharply demarcated borders. Regional lymphatic nodes, mainly retro auricular, were enlarged. Within 48 hours, the patient was treated with acyclovir tablets in a dose of 800 mg three times a day and an antipyretic. Acyclovir ointment was administered during the first two days, as well as tetracycline ointment after the second day of the eruption. On the fifth day, we observed regression of the skin changes (Figure 2), and complete healing was achieved after one week. We

    Herpes zoster is caused by the infection of Varicella-Zoster virus. The anatomical distribution of herpes zoster in the sacral area is only 6. 9%1). Moreover, the onset rate of herpes zoster with urinary dysfunction is 0.6%1). The lesion sites of herpes zoster which cause urinary dysfunction are almost lumber and sacral areas. We describe four cases of sacral herpes zoster with urinary dysfunction in this report. All patients were elderly people (66-84 years old), and all patients were administered anti-virus drugs and alpha 1-adrenergic receptor blockers. Because of urinary retention, three patients have performed clean intermittent self-catheterization (CIC) for several weeks. As the lesions of herpes zoster healed, each patient recovered from urinary dysfunction.

    No vaccines are approved for prevention or treatment of genital herpes. The focus of genital herpes vaccine trials has been on prevention using herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2) alone or combined with glycoprotein B. These prevention trials did not achieve their primary end points. However, subset analyses reported some positive outcomes in each study. The most recent trial was the Herpevac Trial for Women that used gD2 with monophosphoryl lipid A and alum as adjuvants in herpes simplex virus type 1 (HSV-1) and HSV-2 seronegative women. Unexpectedly, the vaccine prevented genital disease by HSV-1 but not HSV-2. Currently, HSV-1 causes more first episodes of genital herpes than HSV-2, highlighting the importance of protecting against HSV-1. The scientific community is conflicted between abandoning vaccine efforts that include gD2 and building upon the partial successes of previous trials. We favor building upon success and present approaches to improve outcomes of gD2-based subunit antigen vaccines.

    Herpes simplex viruses type 1 and type 2 (HSV-1 and HSV-2) are amongst the most common human infectious viral pathogens capable of causing serious clinical diseases at every stage of life, from fatal disseminated disease in newborns to cold sores genital ulcerations and blinding eye disease. Primary mucocutaneous infection with HSV-1 & HSV-2 is followed by a lifelong viral latency in the sensory ganglia. In the majority of cases, herpes infections are clinically asymptomatic. However, in symptomatic individuals, the latent HSV can spontaneously and frequently reactivate, reinfecting the muco-cutaneous surfaces and causing painful recurrent diseases. The innate and adaptive mucosal immunities to herpes infections and disease remain to be fully characterized. The understanding of innate and adaptive immune mechanisms operating at muco-cutaneous surfaces is fundamental to the design of next-generation herpes vaccines. In this paper, the phenotypic and functional properties of innate and adaptive mucosal immune cells, their role in antiherpes immunity, and immunopathology are reviewed. The progress and limitations in developing a safe and efficient mucosal herpes vaccine are discussed. PMID:23320014

    Full Text Available Herpes simplex virus type 1 (HSV-1 with a worldwide distribution has been reported in all human populations, resulting in a clinical spectrum of infections. Although HSV type 2 (HSV-2 is known as the most common cause of genital herpes, an increasing number of cases with genital herpes are caused by HSV-1. The present study aimed to discuss the changes in the epidemiology of HSV-1 infection including the decline in the general incidence of HSV-1 infection in childhood and the increased rate of genital herpes, caused by HSV-1. Moreover, changes in the epidemiology of ocular herpes, i.e., the reduced rate of primary ocular herpes in children and increased incidence of ocular HSV infection in adults, were discussed.

    Full Text Available Intracranial hypertension is a common cause of morbidity in herpes simplex encephalitis (HSE. HSE is the most common form of acute viral encephalitis. Hereby we report a case of HSE in which decompressive craniectomy was performed to treat refractory intracranial hypertension. A 32-year-old male presented with headache, vomiting, fever, and focal seizures involving the right upper limb. Cerebrospinal fluid-meningoencephalitic profile was positive for herpes simplex. Magnetic resonance image of the brain showed swollen and edematous right temporal lobe with increased signal in gray matter and subcortical white matter with loss of gray, white differentiation in T2-weighted sequences. Decompressive craniectomy was performed in view of refractory intracranial hypertension. Decompressive surgery for HSE with refractory hypertension can positively affect patient survival, with good outcomes in terms of cognitive functions.

    Two hundred consecutive patients with herpes zoster attending the skin clinic at the Kilimanjaro Christian Medical Centre (KCMC) were examined and checked for HIV infection. They ranged in age from 10 months to 86 years with the majority in their 20s and 30s. The dermatomes involved were thoracic (97), trigeminal (50), cervical (37), lumbar (19) and sacral (3). Six (3%) had more than one dermatome involved and 2 (1%) had disseminated disease. Only 2 (1%) had severe ulceration of the skin and all healed in less than 4 weeks. In children under the age of 10 years and in adults between the ages of 20 and 49 years virtually 100% were HIV positive; even in the age group 50-59 more than three-quarters were HIV positive. We conclude that the presence of herpes zoster at any site is a good indication that the patient is HIV positive except in the teens and the very elderly.

    Two patients with serologically confirmed herpes simplex encephalitis were studied by serial CT scannings. Case 1, a 60-year-old woman, was admitted to National Cardiovascular Center because of headache, fever, and attacks of Jacksonian seizure. Case 2, a 54-year-old man, was admitted because of fever, consciousness disturbance and right hemiparesis. Pleocytosis (mainly lymphocytes) and elevation of protein content in cerebrospinal fluid were observed in both cases. Both patients presented ''das apallische Syndrom'' one month after admission. The diagnosis of herpes simplex encephalitis was confirmed by typical clinical courses and by greater than fourfold rises in serum antibody titer for herpes simplex virus as well as that in cerebrospinal fluid in case 1. Characteristic CT findings observed in these two cases were summarized as follows: Within a week after the onset, no obvious abnormalities could be detected on CT scans (Case 1). Two weeks after the onset, a large low-density area appeared in the left temporal lobe and in the contralateral insular cortex with midline shift toward the right side (Case 2). One month later, an ill-defined linear and ring-like high-density area (Case 1), or a well-defined high-density area (Case 2), that was enhanced after contrast administration, was observed in the large low-density area in the temporal lobe. These findings were considered as characteristic for hemorrhagic encephalitis. These high-density areas disappeared two months later, however, widespread and intensified low-density areas still remained. In both cases, the basal ganglia and thalamus were completely spared on CT scans. From these observations, it can be concluded that serial CT scannings are quite useful for diagnosis of herpes simplex encephalitis.

    In the last 10 years genital herpes simplex has reached epidemic proportions, affecting 5 million Americans, with 500,000 new cases yearly. The incidence is highest among middle and upper socioeconomic groups and among whites. There are 2 antigenically distinct strains of the herpes simplex virus, and type II is the cause of 85% of the genital infections. The virus has an affinity for tissues derived from the embryonic ectoderm -- skin, mucous membranes, eye, and central nervous system. Transmission is by personal contact with an infected area. The clinical course of the disease involves 4 stages. In the primary stage the typical lesions are vesicles, which rupture, leaving painful shallow ulcerations. The primary stage lasts from 2 to 4 weeks with approximately 10 days of viral shedding. In the latent stage the virus lies dormant in the sacral ganglion and is noninfectious. In the shedding stage the virus replicates and sheds in genital secretions. The recurrent stage is characterized by prodromal itching or tingling sensations prior to the eruption of the vesicles and by neuralgia. Recurrence occurs as often as 4 to 7 times a year and lasts from 7 to 10 days, with viral shedding for 4 or 5 days. Definitive diagnosis can be made from viral tissue culture or the Tzanck and Papanicolaou smears. There is no cure for herpes although acyclovir has been found to shorten the duration of the episodes. Except for pregnancy complications, the most serious complications of recurrent genital herpes are psychological. The disease is socially stigmatizing and inhibits sexual activity. The nurse should provide supportive care, information about the transmission and symptoms of the disease, and counseling as to precautions to take, such as condom and spermicide use, avoidance of oral sex, abstention when lesions are present, and limiting sex to one partner.

  5. Herpes zoster oticus: A rare clinical entity

    2010-01-01

    Full Text Available Herpes zoster oticus also known as Ramsay Hunt syndrome is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus infection in the geniculate ganglion causes otalgia, auricular vesicles, and peripheral facial paralysis. Ramsay Hunt syndrome is rare in children and affects both sexes equally. Incidence and clinical severity increases when host immunity is compromised. Because these symptoms do not always present at the onset, this syndrome can be misdiagnosed. Although secondary to Bell′s palsy in terms of the cause of acute atraumatic peripheral facial paralysis, Ramsay Hunt syndrome, with incidence ranged from 0.3 to 18%, has a worse prognosis. Herpes zoster oticus accounts for about 12% cases of facial palsy, which is usually unilateral and complete and full recovery occurs in only about 20% of untreated patients. The most advisable method to treat Ramsay Hunt syndrome is the combination therapy with acyclovir and prednisone but still not promising, and several prerequisites are required for better results. We present a case of 32-year-old man suffering from Ramsay Hunt syndrome with grade V facial palsy treated effectively with rehabilitation program, after the termination of the combination therapy of acyclovir and prednisone.

  6. Herpes simplex encephalitis : from virus to therapy.

    Herpes simplex virus (HSV) is the cause of herpes simplex encephalitis (HSE), a devastating human disease which occurs in 2-4 cases per million/year. HSE results either from a primary infection or virus reactivation, in accordance with the common pattern of HSV infection which is a chronic lifelong process. However its pathophysiology remains largely unknown and its poor prognosis is in contrast with the usually good tolerance of most clinical herpetic manifestations. HSE is due to HSV type 1 (HSV-1) in most cases but HSV type 2 (HSV-2) may be also implicated, especially in infants in the context of neonatal herpes. Polymerase chain reaction detection of HSV DNA in cerebrospinal fluid is the diagnosis of choice for HSE. Acyclovir, a nucleoside analogue which inhibits viral DNA polymerase activity, is the reference treatment of HSE while foscarnet constitutes an alternative therapy and the efficacy of cidofovir is currently uncertain in that context. The emergence of HSV resistance to acyclovir, a phenomenon which is mainly observed among immunocompromised patients, is a current concern although no case of HSE due to an acyclovir-resistant HSV strain has been reported to date. Nevertheless the identification and development of novel therapeutic strategies against HSV appears to be a non dispensable objective for future research in virology.

    To describe two patients who developed an intracranial hematoma as a complication of temporal lobe encephalitis due to herpes simplex type 1 virus, and to review the literature. The first patient, a 45-year-old woman developed a brain hematoma in the location of the encephalitic lesion on day 9 after the onset of herpes simplex encephalitis (HSE) that required surgical evacuation. The second patient, a 53-year-old woman was being treated for HSE; on day 8 after admission a temporal lobe hematoma with midline shift was disclosed due to persistent headache. Both patients survived but were left with sequelae. We conducted a PubMed/MEDLINE search from 1986 to April 2013 on this topic. We have found 20 additional cases reported in the literature and review their characteristics. Hemorrhage was present on admission in 35% of pooled patients, and consistently involved the area of encephalitis. Clinical presentation of intracranial hemorrhage overlapped the encephalitic symptoms in two-thirds of the patients. Half of patients underwent surgery. Overall, mortality rate was low (5.2%), and half of patients fully recovered. Intracranial bleeding, although infrequent, can complicate the evolution of herpes simplex encephalitis and should be borne in mind since its presence may require neurosurgery. Although its presentation may overlap the encephalitic features, the lack of improvement or the worsening of initial symptoms, particularly during the second week of admission, should lead to this suspicion and to perform a neuroimaging study.

    Herpes zoster is a common disease of adulthood. Its incidence is low in childhood and adolescence. Certain risk factors like hematological malignancies or immunosuppression due to any cause may lead to onset at an early age. There is a unilateral appearance of grouped vesicular eruption on an erythematous background which may involve contiguous dermatomes. Rarely the lesions may occur bilaterally in an otherwise healthy individual. We present a case of herpes zoster, with lesions having atypical distribution involving bilaterally symmetrical dermatomes over the lower chest.(author)

    Little is known about the role of herpes simplex virus (HSV) type 1 (HSV1) in the epidemiology of genital herpes in Canada. Data on herpes viral cultures for two consecutive years obtained from L'Hôpital Dr GL Dumont, which performs all the viral culture testing in New Brunswick, were reviewed. It was hypothesized that HSV1 was the main cause of genital herpes in New Brunswick. Samples of genital origin sent to the laboratory for HSV culture testing between July 2006 and June 2008 were analyzed. Samples from an unspecified or a nongenital source were excluded from analysis. Multiple positive samples collected from the same patient were pooled into a single sample. HSV was isolated from 764 different patients. HSV1 was isolated in 62.6% of patients (male, 55%; female, 63.8%). HSV1 was isolated in 73.2% of patients 10 to 39 years of age and in 32% of patients ≥40 years of age. The difference in rates of HSV1 infection between the 10 to 39 years of age group and the ≥40 years of age group was statistically significant (Pgenital site.

    Although herpes superinfection is a well-known complication of pemphigus, it has not been widely investigated. To investigate the frequency and features of herpes infection in patients with ongoing pemphigus. We carried out a multicenter retrospective study between 2008 and 2016 in patients with newly diagnosed pemphigus presenting active herpes infection. Clinical, virological, immunological and therapeutic data were collated. We performed a literature review for pemphigus and herpes. Among the 191 pemphigus patients, screening for herpes (PCR or culture) was carried out in 11 to 71 % of subjects, depending on the center in question. Twenty-four patients (12 women, mean age 58 years) presented at least one episode of herpes infection. The frequency of positivity ranged from 0 to 42 % by center. Twenty-one cases consisted of pemphigus vulgaris and infection occurred at a mucosal site in 19 patients. Herpes infection was identified at the time of diagnosis in 15 patients and 17 patients received no specific treatment for their pemphigus. The virus was identified using PCR in 23 cases. Ten patients subsequently received prophylactic treatment for herpes. The mean duration of follow-up was 36 months (0-89 months). Thirteen of the 24 patients had 23 relapses of pemphigus; PCR testing for herpes was performed 19 times and was positive in 6 cases (31.5 %). Our study showed wide variation in the incidence of herpes superinfection in patients with pemphigus, reflecting the different screening approach at each center (being performed either routinely or only in the event of strong suspicion). The prognostic value of routine screening for herpes in patients with active pemphigus lesions remains to be demonstrated by further prospective investigations. Copyright © 2018 Elsevier Masson SAS.

The recurrence of herpes zoster is higher in immunocompromised patients and older patients. The purpose of this study is to assess the frequency of herpes zoster recurrence and factors that can influence its recurrence. From January 2005 to December 2015, 14,343 patients with herpes zoster were enrolled in this study. The patients were diagnosed at Hallym University Medical Centers and Kangwon National University Hospital in Seoul, Gyeonggi, and Gangwon. Herpes zoster recurrence and patient characteristics were surveyed by medical record review and a telephonic survey. The overall frequency of herpes zoster recurrence was 1.18%. The frequency of recurrence was higher in women than in men. It was also higher in patients aged 50∼70 years than in patients who were younger or older than this. Additionally, we assessed that the frequency of recurrence was statistically higher in patients with a compromised immune system and in patients who experienced longer lasting pain during their first episode. The frequency of herpes zoster recurrence is more common in women, older age, patient with longer pain duration and immunocompromised patients.

    Full Text Available One hundred and seven cases (6 children and 101 adults of herpes zoster were recruited over a period of two years. The frequency of herpes zoster amongst skin OPD cases was found to be 0.34 per cent. The male to female ratio was 1.74:1. The most common prodromal symptom seen was paresthesia in 25 (23.36% cases followed by itching in 21 (19.62% cases.Most common presenting complaint was pain in 97 (90.65% cases. Ninety nine cases had classical herpes zoster followed by necrotic / ulcerated herpes zoster in 5 cases and hemorrhagic herpes zoster in 3 cases. Thoracic dermatome was the most common dermatome involved in 64 (59.8% cases followed by cervical in 17 (15.8% cases. Unidermatomal involvement was seen in 81 (75.7% cases, followed by multidermatomal in 18 (16.8% cases and disseminated in 8 (7.4% cases. Forty six cases were screened for HIV, out of them; six cases (4 males, 2 females were seropositive for HIV. Classical herpes zoster was a feature in four cases; however, one case each also had necrotic and hemorrhagic form of herpes zoster. To conclude, herpes zoster commonly occurs in young adults in India with presenting symptoms such as pain, itching and fever.

    A half billion people have genital herpes infections worldwide. Approximately one-fifth of American women between ages 14 and 49 are HSV-2 seropositive. The development of an effective genital herpes vaccine is a global health necessity based on the mental anguish genital herpes causes for some individuals, the fact that pregnant women with genital herpes risk transmitting infection to their newborn children, and the observation that HSV-2 infection is associated with a 3-fold to 4-fold increased probability of HIV acquisition. We review the strengths and limitations of preclinical animal models used to assess genital herpes vaccine candidates and the goals of prophylactic and therapeutic vaccines. We also discuss the current pipeline of vaccine candidates and lessons learned from past clinical trials that serve as a stimulus for new strategies, study designs and endpoint determinations.

The acute virus infections jeopardize mankind by their complications with numerous consequences. They open up the way to super infections, they provoke endogenous infections and lead to insufficiency of the vital organs. The viruses penetrate the organism mainly through the respiratory ways, digestive and urinary-sexual organs and skin. Some viruses immediately at the place of their entrance into the organism find receptive cells in which they can multiply (herpes virus and etc.. Some viruses must get through the blood, through the lymph or the nerve fibers to the target organs that they have affinity for.The changes that primarily occur in the mouth with manifest lymphadenopathy of the surrounding area emerge with respect to the type of the acute infection dis-ease.The human herpes viruses are responsible for a great number of diseases in people; that is why it can be said that the infections they induce are a very frequent cause of people's diseases in the world. Man is natural and the only host for the types I and II of the herpes simplex virus (HSV; that is why the infected person is regarded as the source of infection. The infection transmission can be by direct contact or over the contaminated secretions during the sexual intercourse. The age and the socioeconomic status (living conditions, level of medical culture, habits, etc. affect to agreat extent epidemiology of the HSV infection. The HSV distribution in the region of Niš in the five-year period (from 1987 to 1992 was the highest in the early and late summer (June and September.

    To review recent advancements in the management of herpes simplex virus (HSV) epithelial keratitis. Trifluridine eye drop, acyclovir (ACV) ointment, ganciclovir gel, and oral ACV are still the main therapeutic agents. Cryopreserved amniotic membrane has been recently used as an adjuvant treatment. Resistance to ACV has become a concerning issue. The animal models of HSV vaccine are able to reduce HSV keratitis. New antivirals are under development. Current cases of HSV epithelial keratitis are manageable with available medications, but new advancements are required to decrease disease burden in the future. HSV vaccine can be revolutionary.

    Full Text Available Seventy five patients of recurrent genital herpes (RGH treated with oral or topical acyclovir and placebo were compared and followed for periods ranging 4 to 8 years in a prospective study. Oral acyclovir definitely helps RGH patients; it shortens healing time; postpones recurrences and instills confidence in the patients. There is sufficient evidence that RGH dies a natural death with time as seen after 8 years follow up in placebo group patients. Topical use of acyclovir cream is not as useful as believed.

    2004-02-01

    Herpetic genital infection is a common sexually transmitted disease, caused in most cases by type 2 Herpes simplex virus (HSV2). This virus is characterized by its neurotropic properties and its ability to establish latency in sacral sensory ganglions. Some cases of genital primo-infection are complicated by viral replication dissemination to neigbhoring nerve structures like meninges and radicular terminations. In such cases muco-cutaneous manifestations are associated with peripheral neurological impairment in the form of meningo-radiculitis. Physicians should be familiar with these neurological symptoms knowing that they always regress completely. The present report illustrates these complications and reviews the potential neurological implications described in the literature.

    Shingles is a painful rash that results from reactivation of latent varicella-zoster virus in the dorsal root ganglia or cranial nerves. In this article an update is presented on the prevention and pharmacological treatment of the secondary pain from the virus infection. The most effective way to prevent post-herpetic neuralgia and its consequences is the prevention of herpes itself. A live attenuated vaccine (the Oka strain varicella zoster virus) has been available for several years, and is approved in adults aged 50 years old. Although this vaccine has shown to be effective against herpes zoster and post-herpetic neuralgia, its effectiveness decreases with age and is contraindicated in patients with some form of immunosuppression. Today the recombinant vaccines provide an alternative, and may be administered to immunocompromised persons. Copyright © 2016 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

    Herpes simplex virus encephalitis is a common and treatable cause of acute encephalitis in all age groups. Certain radiological features such as temporal parenchymal involvement facilitate the diagnosis. The use of herpes simplex virus polymerase chain reaction has expanded the clinical and imaging spectrum. We report the case of a young patient who presented with a movement disorder and predominant involvement of thalami, brainstem and cerebellum on magnetic resonance imaging, and was diagnosed with herpes simplex virus encephalitis. Differentiation from Japanese encephalitis may be difficult in these patients, especially in endemic areas, and may necessitate the use of relevant investigations in all patients.

    Full Text Available A erupção ectópica e a impacção de caninos superiores são problemas bastante comuns na população. A excelência do tratamento ortod��ntico traduz-se na correção da oclusão, harmonia do sorriso, saúde periodontal e estabilidade pós-tratamento. Para obtermos tais condições, a manutenção dos caninos é fundamental. Portanto, o objetivo deste estudo foi avaliar radiograficamente a localização de caninos superiores não irrompidos utilizando-se radiografias panorâmicas. Foram selecionadas setenta radiografias panorâmicas de pacientes com impacção uni ou bilateral de caninos, candidatos a tratamento cirúrgico. Para determinação da posição espacial dos caninos superiores não irrompidos foram selecionados métodos descritos na literatura e uma avaliação proposta neste trabalho. A localização de caninos não irrompidos é fundamental para estabelecer o plano de tratamento, auxiliando no acesso cirúrgico e na direção das forças ortodônticas a serem aplicadas no dente impactado. Os pacientes que tiveram suas radiografias utilizadas neste estudo serão tratados pelas disciplinas de Ortodontia e Cirurgia, com exodontia do canino ou exposição cirúrgica para colagem do dispositivo de tracionamento associada ao tratamento ortodôntico corretivo.Ectopic eruption and the impaction of upper canines are problems quite commonly presented by the population.

    The lysate and recombinant antigens of various production included informula of ELISA-test-systems were analyzed. The ELISA-test-systems are used for detection of IgG to Herpes simplex virus type I and II. For testing the panel of serums PTH 201 (BBI Inc.) were used. The samples of this panel contain antibodies to Herpes simplex virus type I and II in mixed titers. The 69 serums of donors were used too (17 samples had IgG to Herpes simplex virus type I, 23 samples to Herpes simplex virus type II and 29 samples had no antibodies to Herpes simplex virus). The diagnostic capacity of mixture of recombinant antigens gG1 Herpes simplex virus type I and gG2 Herpes simplex virus type II (The research-and-production complex "DiaprofMed") was comparable with mixture of lysate antigen Herpes simplex virus type I and II (Membrane) EIE Antigen ("Virion Ltd."). In the test-systems for differentiation of IgG to Herpes simplex virus type I the recombinant antigen gG1 Herpes simplex virus type I proved to be comparable with commercial analogue Herpes simplex virus-1 gG1M ("Viral Therapeutics Inc."'). At the same time, capacity to detect IgG to Herpes simplex virus type II in recombinant protein gG2 Herpes simplex virus type II is significantly higher than in its analogue Herpes simplex virus-2 gG2c ("Viral Therapeutics Inc.").

    Recently, Herpes simplex virus (HSV)-1 seroprevalence declined among adolescents, rendering young people lacking HSV-1 antibodies more susceptible to genital HSV-1 acquisition, if sexually exposed. The aim of the present study was to identify the possible risk factors for the development of HSV-1 related herpes genitalis (HG). From January 2012 to December 2015, patients with HG attending three Sexually Transmitted Infections Units in Northern Italy were recruited. A genital swab on the lesions for the search of HSV-1/2 DNA through Real time polymerase chain reaction (PCR) and a serum sample for HSV-1/2 specific serology were performed. Moreover, patients were asked whether they had personal history of herpes labialis (HL). Patients with PCR proved HSV-1 HG were included as cases; asymptomatic subjects attending STI Units for a blood check were recruited as controls and were checked for HSV-1/2 serology. 141 cases and 70 controls were enrolled. Specific HSV-1 antibodies were found in 34.7% of the cases and 67% of the controls. History of recurrent herpes labialis (RHL) was found in 4% of the cases and 31% of the controls. The occurrence of RHL in HSV-1 seropositive patients resulted lower in the case group compared to the control group. We can speculate about a protective role for RHL against the clinical appearance of HSV-1 HG. The clinical usefulness of our study involved especially the counseling in serodiscordant couples. The presence of HSV-1 antibodies in asymptomatic sexual partners does appear protective for HG manifestation only in presence of RHL history.

    Newborn infants are a population which is especially susceptible to viral infections that frequently affect the central nervous system. Herpes infections can be transmitted to the foetus and to the newborn infant, and give rise to severe clinical conditions with long-term sensory and cognitive deficits. Two thirds of newborn infants with encephalitis due to herpes simplex virus and half of the children with symptomatic congenital infection by cytomegalovirus develop sequelae, which results in high community health costs in the long term. Fortunately, the better knowledge about these infections gained in recent years together with the development of effective antiviral treatments have improved the patients' prognosis. Valganciclovir (32 mg/kg/day in two doses for six months) prevents the development of hypoacusis and improves the neurological prognosis in symptomatic congenital infection due to cytomegalovirus. Acyclovir (60 mg/kg/day in three doses for 2-3 weeks) prevents the development of severe forms in skin-eyes-mouth herpes disease, and lowers the rate of mortality and sequelae when the disease has disseminated and is located in the central nervous system.

    2016-02-01

    Type 1 herpes simplex virus (HSV-1) is very prevalent yet in rare circumstances can lead to fatal neonatal disease. Genital acquisition of type 2 HSV is the usual mode for neonatal herpes, but HSV-1 transmission by genital or extragenital means may result in greater mortality rates. A very rare scenario is presented in which the mode of transmission was likely through breast lesions. The lesions were seen by nurses as well as the lactation consultant and obstetrician in the hospital after delivery of the affected baby but not recognized as possibly being caused by herpes. The baby died 9 days after birth with hepatic failure and disseminated intravascular coagulation. Peripartum health care workers need to be aware of potential nongenital (including from the breast[s]) neonatal herpes acquisition, which can be lethal. © The Author(s) 2015.

    Full Text Available “Wolf’s isotopic response” describes the occurrence of a new skin disorder at the site of another, unrelated and already healed skin disease. In most cases of isotopic response, the initial dermatosis is herpes zoster, herpes simplex, varicella, thrombophlebitis, scrofuloderma and striae distense. The most frequent second dermatoses are granulomatous reactions, particularly granuloma annulare, and lichenoid diseases. Various etiological reasons including viral, immunologic, neural and vascular have been put forth. We report here a case in which the second disease was herpes zoster that appeared over the same dermatomes of pre-existing segmental vitiligo. The occurrence of vitiligo as first and herpes zoster as second disease in the “Wolf’s isotopic response” has not, to the best of our knowledge, been reported previously.

    The epidemiology, clinical course, diagnosis, and attempted treatments of herpes genitalis are reviewed. Herpes genitalis is an increasingly common sexually transmitted disease for which there is no effective treatment. It can occur in either sex and is mot commonly first found in patients 14 to 29 years old. Initial exposure to the virus may result in prolonged local symptoms (pain, itching, discharge) and signs (ulcerative lesions) as well as fever, malaise, myalgias, and fatigue. After the initial exposure, the virus may be found in a latent stage in the dorsal nerve root ganglia in the sacral area, and recurrences of disease may ensue. The frequency and clinical course of recurrent genital herpes can be of varying duration and severity. Although antiviral substances, immune potentiators, topical surfactants, and photodynamic inactivation have been used to treat genital herpes infections, there is no proven effective therapy.

    The herpesviruses HSV-1 and -2 classically infect the oral and genital area respectively. They descend from a common ancestor but have evolved separately since several million years, getting each adapted to these areas. Thus, while both can infect either site, HSV-1 reactivates often orally, while HSV-2 does so in the genital area. The followings facts are stressed, because we think they are new, or worth attention regarding HSV epidemiology (plateauing of the HSV-2 epidemic in the US, growing share of HSV-1 as a genital herpes agent), clinical expression (extra-oral and extra-genital lesions, severity of gingivostomatitis), diagnosis (confusing herpes and zoster in the trigeminal and sacral areas) and treatment (relative worth of suppressive and episodic treatments of genital herpes, as well as shortening of these latter, and treatment of gingivostomatitis and herpes labialis).

    Herpes simplex infections are potentially a life-threatening situation for immunocompromised as well as critically ill patients. The correct diagnosis is made more difficult in comatose patients by the fact that the characteristic symptom of extreme pain cannot be registered. The clinical dermatological findings (polycyclic configuration, easily bleeding ulcers) are thus especially important in patients under intensive care conditions. As examples, the cases of 3 critically ill patients (subarachnoid bleeding or head injury) developing therapy-resistant, flat sacral or perioral skin ulcers with peripheral blisters are presented. Herpes simplex virus was confirmed immunohistologically and in the smear test. All patients subsequently died. These cases emphasize that patients in the intensive care unit are in danger of developing a chronic persistent Herpes simplex infection due to latent immunosuppression. Chronic persistent Herpes infections may be underrated in intensive therapy, and must always be ruled out in case of therapy-resistant erosions or ulcerations.

    A case of sacral herpes zoster infection in a 56-year-old man with the complication of loss of urinary voiding sensation is presented. He had typical herpes zoster eruption on the left S2 dermatome, hypalgesia of the S1-S4 dermatomes, and absence of urinary voiding sensation. There was no other urinary symptom at the first medical examination. Urinary complications associated with herpes zoster are uncommon, but two types, acute cystitis and acute retention, have been recognized. No cases of loss of urinary voiding sensation due to herpes zoster have been reported. In this case, hypalgesia of the sacral dermatomes was mild compared to the marked loss of urethral sensation. This inconsistency is explained by the hypothesis that the number of urethral fibers is very small as compared to that of cutaneous fibers, therefore, urethral sensation would be more severely disturbed than cutaneous sensation.

    Aim of the study was to determine clinical usefulness of direct immunofluorescence method in the laboratory diagnosis of genital herpes in women. Overall 187 anogenital swabs were collected from 120 women. Using a dacron-tipped applicator 83 swabs were collected from women suspected of genital herpes and 104 from patients with no signs of genital infection. All samples were tested using cell culture (Vero cell line) and then direct immunofluorescence method (DIF) for the identification of antigens of herpes simplex viruses: HSV-1 and HSV-2. Characteristic cytopathic effect (CPE), indicative of alphaherpesvirus infection, was observed in 43.4% of cultures with clinical specimens collected from women with suspected genital herpes and in 29.8% of cultures of clinical specimens taken from patients with no clinical symptoms of genital herpes. Herpes simplex viruses were determined in 73 samples by direct immunofluorescence method after amplification of the virus in cell culture. The DIF test confirmed the diagnosis based on the microscopic CPE observation in 85%. In 15% of samples (taken from pregnant women without clinical signs of infection) we reported positive immunofluorescence in the absence of CPE. The frequency of antigen detection was statistically significantly higher in samples that were positive by culture study (chi-square test with Yates's correction, p genital herpes in swabs taken from the vestibule of the vagina and the vulva. However, there was no statistically significant difference in the frequency of detection of Herpes Simplex Virus antigens in specimens from different parts of the genital tract in both groups of women (chi-square test, p > 0.05). In our study HHV-1 was the main causative agent of genital herpes. The growing worldwide prevalence of genital herpes, challenges with the clinical diagnosis, and availability of effective antiviral therapy are the main reasons for a growing interest in rapid, proper laboratory diagnosis of infected

    Herpes zoster and an associated complication, postherpetic neuralgia, are both attributable to the varicella zoster virus. This virus, which lies dormant within the affected sensory ganglia after an initial infection, appears to be triggered in part by a decrease in immunity. According to available research, stress, stressful life events, and depressive symptoms are identified antecedents to outbreaks of herpes zoster. Likewise, the development of postherpetic neuralgia has been associated wi...

    To examine the risks of genital herpes and antiherpes treatment during pregnancy in relation to preterm delivery (PTD), we conducted a multicenter, member-based cohort study within 4 Kaiser Permanente regions: northern and southern California, Colorado, and Georgia. The study included 662,913 mother-newborn pairs from 1997 to 2010. Pregnant women were classified into 3 groups based on genital herpes diagnosis and treatment: genital herpes without treatment, genital herpes with antiherpes treatment, and no herpes diagnosis or treatment (unexposed controls). After controlling for potential confounders, we found that compared with being unexposed, having untreated genital herpes during first or second trimester was associated with more than double the risk of PTD (odds ratio (OR) = 2.23, 95% confidence interval (CI): 1.80, 2.76). The association was stronger for PTD due to premature rupture of membrane (OR = 3.57, 95% CI: 2.53, 5.06) and for early PTD (≤35 weeks gestation) (OR = 2.87, 95% CI: 2.22, 3.71). In contrast, undergoing antiherpes treatment during pregnancy was associated with a lower risk of PTD compared with not being treated, and the PTD risk was similar to that observed in the unexposed controls (OR = 1.11, 95% CI: 0.89, 1.38). The present study revealed increased risk of PTD associated with genital herpes infection if left untreated and a potential benefit of antiherpes medications in mitigating the effect of genital herpes infection on the risk of PTD. © The Author 2014.

    Full Text Available Management of genital herpes is complex. Apart from using the standard antivirals, an ideal management protocol also needs to address various aspects of the disease, including the psychological morbidity. Oral acyclovir, valacyclovir or famciclovir are recommended for routine use. Long-term suppressive therapy is effective in reducing the number of recurrences and the risk of transmission to others. Severe or disseminated disease may require intravenous therapy. Resistant cases are managed with foscarnet or cidofovir. Genital herpes in human immunodeficiency virus-infected individuals usually needs a longer duration of antiviral therapy along with continuation of highly active anti retroviral therapy (HAART. Genital herpes in late pregnancy increases the risk of neonatal herpes. Antiviral therapy and/or cesarean delivery are indicated depending on the clinical circumstance. Acyclovir appears to be safe in pregnancy. But, there is limited data regarding the use of valacyclovir and famciclovir in pregnancy. Neonatal herpes requires a higher dose of acyclovir given intravenously for a longer duration. Management of the sex partner, counseling and prevention advice are equally important in appropriate management of genital herpes. Vaccines till date have been marginally effective. Helicase-primase inhibitors, needle-free mucosal vaccine and a new microbicide product named VivaGel may become promising treatment options in the future.

    Full Text Available Os primeiros herpes-vírus a serem descritos foram os tipos 1 e 2, cuja denominação é herpes simplex 1 e 2 ou HSV-1 e HSV-2. Estes vírus possuem características biológicas particulares, tais como a capacidade de causar diferentes tipos de doenças, assim como estabelecer infecções latentes ou persistentes por toda a vida dos hospedeiros e de serem reativados causando lesões que podem se localizar no sítio da infecção primária inicial ou próxima a ele. Postula-se que a reativação deste vírus no gânglio geniculado esteja relacionada com a paralisia de Bell. Nesta situação, os vírus, que estariam latentes neste gânglio, sofreriam reativação e replicação difundindo-se pelo nervo facial e seus ramos, dentre eles o nervo corda do tímpano, que ao estimular a secreção salivar possibilitaria a identificação do DNA viral na saliva dos pacientes. Até recentemente, um grande número de pacientes eram diagnosticados como portadores de uma forma desta paralisia, chamada de idiopática ou de paralisia de Bell. Com o advento da técnica de estudo do DNA viral pelo método da reação da polimerase em cadeia (PCR, diversos autores encontraram DNA do vírus herpes simplex tipo I no líquido cefalorraquidiano, na secreção lacrimal, na saliva e nos gânglios geniculados de pacientes com paralisia de Bell. OBJETIVO: observar a prevalência do vírus herpes simplex tipo I pela técnica de PCR, na saliva de pacientes com PFP de Bell, relacionando-a com a evolução clínica destes casos. METODOLOGIA: Avaliamos 38 pacientes portadores de Paralisia Facial Periférica de Bell, que foram submetidos a anamnese, exame médico geral e otorrinolaringológico e coleta de saliva para detecção do DNA viral pela técnica de PCR. O grupo controle correspondeu a 10 adultos normais. RESULTADOS: Obtivemos positividade para o DNA viral em 11 casos dos 38 avaliados, o que corresponde a 29% da amostra.

    We retrospectively analyzed the MR findings of 12 patients with herpes simplex encephalitis (HSE) (8 months - 64 years old). MR imaging was performed on either a 0.5T (6 patients) or 2.0T (6 patients) superconducting unit with spin echo pulse sequences. The most common and characteristic MR finding consisted of non-hemorrhagic lesions in the cortices of the temporal lobes(12), and insular(6), either bilateral(7) or unilateral(5). The frontal lobe and cingulate gyrus were involved in 4 and 2 patients respectively. Petechial hemorrhage was found in 3 patients. Non-hemorrhagic lesions were shown as high signal intensities on proton and T2WI, and iso- or low signal intensities on T1WI. In conclusion, MR imaging findings described above appear to be characteristic of HSE and were found to be extremely valuable in the diagnosis of HSE

    One of the most common sexually transmitted infections is the herpes simplex virus (HSV) Type 2. Although the incidence of newborn infection is not as common as in adults, approximately 1,500 neonates are diagnosed annually with HSV infection. HSV can be detrimental to the life of a newborn, with morbidity and mortality rates of up to 65 percent. This article addresses the maternal and fetal complications of HSV and the impact of HSV on the newborn along with diagnostic evaluation methods. In addition, treatment options and evidence-based practices regarding HSV are defined. Despite growing technology and medical treatment for early identification of HSV, this virus remains challenging and can deeply impact the life of an infant and his or her family. Early diagnosis, treatment, and intervention of an infant with HSV are crucial to ensure the livelihood of the newborn.

    Herpes simplex virus encephalitis (HSE) is the most frequent viral encephalitis, as a rule with the starting point and centre within the temporal lobe. If untreated, HSE is usually fatal, thus diagnosis has to be established rapidly. Treatment with Acyclovir should begin as soon possible. As MRI is extremely sensitive in detecting the early inflammatory changes, it should be initially performed, especially as in the early stadium CT may be unspecific. We recommend the following examination protocol: coronar T1-weighted MR imaging before and after administration of gadopentetate dimeglumine, coronar FLAIR sequence and axial T2-weighted imaging. The diagnostic proof is to show the evidence of viral DNA by polymerase chain reaction (PCR) in cerebrospinal liquor. (orig.) [de

    Bovine herpes virus 1 (BHV-1) is primarily associated with clinical syndromes such as rhinotracheitis, pustular vulvovaginitis and balanoposthitis, abortion, infertility, conjunctivitis and encephalitis in bovine species. The main sources of infection are the nasal exudates and the respiratory droplets, genital secretions, semen, fetal fluids and tissues. The BHV-1 virus can become latent following a primary infection with a field isolate or vaccination with an attenuated strain. The viral genomic DNA has been demonstrated in the sensory ganglia of the trigeminal nerve in infectious bovine rhinotracheitis (IBR) and in sacral spinal ganglia in pustular vulvovaginitis and balanoposthitis cases. BHV-1 infections can be diagnosed by detection of virus or virus components and antibody by serological tests or by detection of genomic DNA by polymerase chain reaction (PCR), nucleic acid hybridization and sequencing. Inactivated vaccines and modified live virus vaccines are used for prevention of BHV-1 infections in cattle; subunit vaccines and marker vaccines are under investigation.

    Herpes simplex virus is a common virus that causes a variety of clinical presentations ranging from mild to life-threatening. Orolabial and genital herpes are common disorders that can often be managed in an outpatient setting; however, some patients do present to the emergency department with those conditions, and emergency clinicians should be aware of possible complications in the pediatric population. Neonatal herpes is a rare disorder, but prompt recognition and initiation of antiviral therapy is imperative, as the morbidity and mortality of the disease is high. Herpes encephalitis is an emergency that also requires a high index of suspicion to diagnose. Herpes simplex virus is also responsible for a variety of other clinical presentations, including herpes gladiatorum, herpetic whitlow, eczema herpeticum, and ocular herpes. This issue reviews the common clinical presentations of the herpes simplex virus, the life-threatening infections that require expedient identification and management, and recommended treatment regimens.

Apesar da forma ulcerativa ser a mais conhecida, a literatura relata o aparecimento de lesões tumorais, nodulares ou hipertróficas relacionadas ao vírus. O exame proctológico mostra tumores dolorosos, achatados, com superfície recoberta por ulceração rasa e com bordas bem delimitadas, elevadas e lobuladas, localizados na margem anal e/ou no sulco interglúteo, algumas vezes imitando condilomas virais ou carcinoma. A anamnese revela instalação insidiosa com crescimento lento e progressivo, além da história de tratamentos anteriores para úlceras herpéticas. O diagnóstico diferencial com carcinoma impõe a realização de biópsia para confirmação histológica. Esse exame revela hiperplasia epitelial moderada e denso processo inflamatório com linfócitos e plasmócitos. Células gigantes e multinucleadas são observadas na epiderme.

    We treated 437 cases of adult aseptic meningitis and 12 cases (including 2 recurrent patients; age, 31.8 ± 8.9 years; 7 females) of herpes simplex meningitis from 2004 to 2016. The incidence rate of adult herpes simplex meningitis in the cases with aseptic meningitis was 2.7%. One patient was admitted during treatment of genital herpes, but no association was observed between genital herpes and herpes simplex meningitis in the other cases. The diagnoses were confirmed in all cases as the cerebrospinal fluid (CSF) was positive for herpes simplex virus (HSV)-DNA. For diagnosis confirmation, the DNA test was useful after 2-7 days following initial disease onset. Among other types of aseptic meningitis, the patients with herpes simplex meningitis showed relatively high white blood cell counts and relatively high CSF protein and high CSF cell counts. CSF cells showed mononuclear cell dominance from the initial stage of the disease. During same period, we also experienced 12 cases of herpes simplex encephalitis and 21 cases of non-hepatic acute limbic encephalitis. Notably, the patients with herpes simplex meningitis were younger and their CSF protein and cells counts were higher than those of the patients with herpes simplex encephalitis.

    Full Text Available Background: Even though herpes zoster is a common condition its incidence and pattern of occurrence in the era of HIV disease is significant. Aim: To analyze the incidence, pattern of occurrence and evolution of herpes zoster with special attention to provocative factors if any. Materials and Method s: This was an analytical study conducted for 2 years based on a preformed proforma containing preliminary information, a detailed clinical evaluation regarding the segment of involvement, morphology, pattern of lesions, complications, disseminations etc. and investigations to establish provocative factors if any. Results: Incidence of herpes zoster was mainly in the fourth and third decades of life. A definite history of chicken pox was present in only 63.4% cases. In the majority (70% herpes zoster occurred spontaneously. In 30% cases, immunosuppression due to chemotherapy, malignancy, HIV infection, diabetes mellitus were observed. The commonest segment affected was thoracic (42.4% followed by cranial (28.2% and cervical (12.1%. Majority resolved in 7-14 days except immunosuppressed. 34.6% of the patients had complications such as secondary bacterial infection, post herpetic neuralgia, and motor weakness. Ten patients had HIV infection as a provocative factor. Conclusion: The results of incidence and clinical pattern of herpes zoster is almost parallel to the previous studies. Any factors of immunosuppression should be checked, especially HIV, particularly in disseminated and long-lasting cases.

    Full Text Available Introduction. Pityriasis lichenoides is a rare, acquired spectrum of skin conditions of an unknown etiology. Case Report. A 28-year-old man presented with recurrent outbreaks of herpes simplex virus associated with the onset of red-to-brown maculopapules located predominantly in trunk in each recurrence. Positive serologies to herpes simplex virus type 2 were detected. Histopathological examination of one of the lesions was consistent with a diagnosis of pityriasis lichenoides chronica. Discussion. Pityriasis lichenoides is a rare cutaneous entity of an unknown cause which includes different clinical presentations. A number of infectious agents have been implicated based on the clustering of multiple outbreaks and elevated serum titers to specific pathogens (human immunodeficiency virus, cytomegalovirus, Epstein-Barr virus, Toxoplasma gondii, and herpes simplex virus. In our patient, resolution of cutaneous lesions coincided with the administration of antiviral drugs and clinical improvement in each genital herpes recurrence. In conclusion, we report a case in which cutaneous lesions of pityriasis lichenoides chronica and a herpes simplex virus-type 2-mediated disease have evolved concomitantly.

  15. Herp enhances ER-associated protein degradation by recruiting ubiquilins

    International Nuclear Information System (INIS)

    Kim, Tae-Yeon; Kim, Eunmin; Yoon, Sungjoo Kim; Yoon, Jong-Bok

    2008-01-01

    ER-associated protein degradation (ERAD) is a protein quality control system of ER, which eliminates misfolded proteins by proteasome-dependent degradation and ensures export of only properly folded proteins from ER. Herp, an ER membrane protein upregulated by ER stress, is implicated in regulation of ERAD. In the present study, we show that Herp interacts with members of the ubiquilin family, which function as a shuttle factor to deliver ubiquitinated substrates to the proteasome for degradation. Knockdown of ubiquilin expression by small interfering RNA stabilized the ERAD substrate CD3δ, whereas it did not alter or increased degradation of non-ERAD substrates tested. CD3δ was stabilized by overexpressed Herp mutants which were capable of binding to ubiquilins but were impaired in ER membrane targeting by deletion of the transmembrane domain. Our data suggest that Herp binding to ubiquilin proteins plays an important role in the ERAD pathway and that ubiquilins are specifically involved in degradation of only a subset of ubiquitinated targets, including Herp-dependent ERAD substrates

    Herpes zoster is a common viral infection of skin caused by reactivation of varicella zoster virus infection from the spinal ganglia. The clinico-epidemiological patterns of this disease in an Indian setting required to be studied. A cross sectional study was conducted on all consecutive cases of herpes zoster reporting to the Dermatology Outpatient Department at a Tertiary Care Hospital in Bangalore during a period of one year from 01 Jun 2013 to 31 May 2014. Detailed history, examination, HIV screening and Tzanck smear were carried out in all cases. 84 cases of herpes zoster were seen with a mean age of 30 years. Majority (39%) of cases were seen in the 21-30 year age group. Thoracic segments were involved in 65.4%, cervical in 11.9%, cranial in 11.5%, lumbar in 8.3% and sacral segments in 3.5%. 63% of cases had zoster associated pain. One case had motor involvement.3.57% of the patients were HIV positive. This study shows a lower age incidence of herpes zoster HIV positivity and zoster associated pain as compared to other studies. The pattern of segmental involvement in herpes zoster seen in this study was similar to other studies.

    The clinical course and complications of 268 patients with first episodes and 362 with recurrent episodes of genital herpes infection were reviewed. Symptoms of genital herpes were more severe in women than in men. Primary first-episode genital herpes was accompanied by systemic symptoms (67%), local pain and itching (98%), dysuria (63%), and tender adenopathy (80%). Patients presented with several bilaterally distributed postular ulcerative lesions that lasted a mean of 19.0 days. Herpes simplex virus was isolated from the urethra, cervix, and pharynx of 82%, 88%, and 13% of women with first-episode primary genital herpes, and the urethra and pharynx of 28% and 7% of men. Complications included aseptic meningitis (8%), sacral autonomic nervous system dysfunction (2%), development of extragenital lesions (20%), and secondary yeast infections (11%). Recurrent episodes were characterized by small vesicular or ulcerative unilaterally distributed lesions that lasted a mean of 10.1 days. Systemic symptoms were uncommon and 25% of recurrent episodes were asymptomatic. The major concerns of patients were the frequency of recurrences and fear of transmitting infection to partners or infants.

    Chronic viral infections are difficult to treat, and new approaches are needed, particularly those aimed at reducing reactivation by enhancing immune responses. Herpes simplex virus (HSV) establishes latency and reactivates frequently, and breakthrough reactivation can occur despite suppressive antiviral therapy. Virus-specific T cells are important to control HSV, and proliferation of activated T cells requires increased metabolism of glutamine. Here, we found that supplementation with oral glutamine reduced virus reactivation in latently HSV-1-infected mice and HSV-2-infected guinea pigs. Transcriptome analysis of trigeminal ganglia from latently HSV-1-infected, glutamine-treated WT mice showed upregulation of several IFN-γ-inducible genes. In contrast to WT mice, supplemental glutamine was ineffective in reducing the rate of HSV-1 reactivation in latently HSV-1-infected IFN-γ-KO mice. Mice treated with glutamine also had higher numbers of HSV-specific IFN-γ-producing CD8 T cells in latently infected ganglia. Thus, glutamine may enhance the IFN-γ-associated immune response and reduce the rate of reactivation of latent virus infection.

    The CT findings in six patients with confirmed herpes simplex encephalitis were analysed and compared with the literature. Thirty-four examinations were performed, 27 within the first 14 days of the illness. The early findings show three characteristic features: The CT may be entirely normal up to the fourth day. Consistent with clinical and E.E.G. findings there then develops a hypodense temporal lesion which, even at this stage, acts as an expanding lesion in half the patients. Between the sixth and eighth day there is frequently involvement of the contra-lateral temporal lobe, not as a continuation, but as a new lesion. At the same time, or after several days, there is involvement of the basal portions of the frontal lobes. In this late phase there may be necrosis in the basal ganglia, thalamus or other parts of the brain. The CT findings in this late phase are uniform and characteristic of the disease. For early diagnosis and treatment the early clinical, electrophysiological and neuro-radiological findings are important. A normal CT scan two days after the onset of clinical symptoms may be regarded as significant. (orig.) [de

    Full Text Available OBJETIVO: avaliar o tempo de retração e o grau da inclinação sofrida pelo canino empregando três tipos de molas ortodônticas para retração - a alça em "T", a alça em "L" e a alça em forma de gota. MÉTODOS: foram utilizados três tipos de fio - aço inoxidável da marca comercial Morelli, aço inoxidável da marca comercial 3M Unitek e liga de beta-titânio da marca comercial Ormco; todos de calibre 0,019" x 0,025". A amostra resultante da combinação dos fatores mola e fio foi submetida à avaliação em modelo de typodont específico para essa finalidade. RESULTADOS: com relação ao tempo de fechamento das alças, verificou-se que um fechamento mais lento, e consequentemente com menor liberação de forças, foi obtido com o desenho de alça em "T" e, ainda, empregando-se a liga de beta-titânio para sua confecção. No que diz respeito à inclinação gerada pelas alças, as alças em forma de gota promoveram uma inclinação dentária maior do que as demais avaliadas. As alças em "T", por outro lado, mantiveram-se relacionadas estatisticamente aos menores valores de inclinação. Porém, quando se empregou o fio de aço inoxidável da marca comercial 3M Unitek para sua confecção, os três tipos de alça não apresentaram diferença estatisticamente significante. CONCLUSÃO: independentemente do desenho de alça empregado, aquelas construídas com liga de beta-titânio mantiveram-se relacionadas estatisticamente aos menores valores de inclinação observados para o elemento dentário movimentado.OBJETIVE: Evaluate the cuspid's retraction time and tipping effects, after submitting it to three different orthodontic retraction loops: the "T" loop, the "boot" loop, and the "tear drop" loop.

    Full Text Available Herpes zoster of the trigeminal nerve branches caused by varicella zoster is a clinical entity consisting of erythematous macules, papules, vesicles, bullae, small ulcers and erythematous plaques, with characteristic short acute/pre-eruptive phases and long herpetic periods with pain. It is caused by reactivation of latent varicella infection. Herpes zoster is a less common endemic disease compared to varicella. During the prodromal stage, the only presenting symptom may be odontalgia, which may prove to be a diagnostic challenge for the dentist. Emergency treatment for a misdiagnosis such as trigeminal neuralgia, odontalgia, and acute pulpitis, as well as complications reported in literature such as tooth resorption, periapical lesions, periodontal destructions, and osteomyelitis may cause an irreversible damage to the patient. Hence, the dentist must be familiar with the presenting signs and symptoms in prodrome of herpes zoster infection of trigeminal nerve. The present article focuses on the pathogenesis, clinical picture, difficulties in diagnosis and management of such cases.

    Full Text Available The most common sites of herpes simplex virus (HSV infection are around the oral cavity and the genitalia. However, HSV can infect any skin or mucous membrane surface. One uncommon site of HSV infection is the breast. Reports of herpetic breast infections are predominantly cases of transmission from a systemically HSV-infected neonate to the mother during breast-feeding. A review of the literature identified only six reports suggesting HSV breast lesions acquired by means other than through an infected infant. Of these, only one report suggests HSV transmission to the breast from a male sexual partner. A second case of clinically unsuspected symptomatic herpes mastitis presumably acquired from sexual contact in a 46-year-old woman is presented. Herpes simplex type 1 was isolated by using polymerase chain reaction and restriction fragment length polymerization techniques. The purpose of this report is to alert physicians to HSV mastitis.

    Full Text Available Herpes simplex virus (HSV types 1 and 2 cause genital herpes infections and are the most common cause of genital ulcer disease in industrialized nations. Although these infections are very common, the majority of them remain underdiagnosed because they are asymptomatic or unrecognized. A clinical diagnosis of genital herpes should always be confirmed by laboratory testing; this can be accomplished through the use of direct tests for viral isolation, the detection of antigen or, more recently, the detection of HSV DNA using molecular diagnostic techniques. Testing for serotypes is recommended because of the different prognostic and counselling implications. Type-specific HSV serology is becoming more readily available and will enhance the ability to make the diagnosis and guide clinical management in select patients.

    There are many causes of acute urinary retention. Reported here is a case of one of the more rare causes: herpes zoster. Fewer than 70 cases have been reported in the literature since 1890. In the present clinical environment where many patients are immunocompromised, reports of herpes zoster and its sequelae are no longer thought of as anecdotal. The virus may interrupt the detrusor reflex due to involvement of the sacral dorsal root ganglia. Urinary retention with sensory loss of both bladder and rectum as well as flaccid paralysis of the detrusor can develop in patients with herpes zoster. Fortunately, the outcome of this process is benign and full recovery of the detrusor is likely.

    Acute herpes-zoster infection is a painful dermatomal lesion that can be manifested by a wide array of neurologic symptoms. We present a 55-year-old female with non-Hodgkin's lymphoma, who developed a left sciatic pain involving the S roots. Two weeks later, the patient developed fever and vesicular rash over the left gluteal area. Herpes-zoster infection was diagnosed and confirmed by the presence of immunoglobulin M (IgM) antibodies against varicella-zoster. The pain and rash resolved, after treatment with acyclovir. In the appropriate clinical setting, sacral herpes-zoster infection ought to be considered in the differential diagnosis of new-onset sciatic pain.

    Full Text Available In spite of the advances in transmission electronic microscopy (TEM, there are few studies presenting a systematic description of the canine spermatozoa and they are only focused on sperm cell heads. The goal of the present study was to describe ultrastructural appearance of canine fresh and frozen-thawed spermatozoa, focusing on damages induced by freezing-thawing in different sperm regions. Ten ejaculates from five proven stud dogs (two ejaculates/dog were collected, evaluated, extended in Tris-egg yolk-glycerol, frozen and stored in liquid nitrogen, and thawed six weeks later.  Samples were evaluated for progressive motility, morphology, and for ultrastructural analysis by TEM. Concerning to TEM, the most striking differences between fresh and frozen-thawed samples were observed over the mid-piece since the fresh spermatozoa showed a well preserved mid-piece. However, the frozen-thawed spermatozoa mid-piece showed signs of damage such as mitochondrial vacuolization. In conclusion, freezing-thawing processes using a Tris-egg yolk extender induce ultrastructural damages in head and mid-piece of canine sperm, affecting the mitochondrial ultrastructure besides.

    Herpes simplex encephalitis (HSE) can be complicated by adverse events in the acute phase. We herein present the case of a 71-year-old woman with HSE complicated by cerebral hemorrhage. She presented with acute deterioration of consciousness and fever and was diagnosed with HSE based on the detection of herpes simplex virus-1 in the cerebrospinal fluid by a polymerase chain reaction. The cerebral hemorrhage developed during acyclovir therapy; however, its diagnosis was delayed for 2 days. After the conservative treatment of the cerebral hemorrhage, the patient made a near-complete recovery. Cerebral hemorrhage should be considered as an acute-phase complication of HSE.

    Ultaviolet enhanced (Weigle) reactivation of UV-irradiated herpes simplex virus in UV-irradiated CV-1 monkey kidney cell monolayers was decreased by caffeine. X-ray enhanced reactivation of UV-irradiated virus in X-irradiated monolayers (X-ray reactivation) and UV- or X-ray-inactivated capacity of the cells to support unirradiated virus plaque formation were unaffected by caffeine. The results suggest that a caffeine-sensitive process is necessary for the expression of Weigle reactivation for herpes virus. Since cafeine did not significantly affect X-ray reactivation, different mechanisms may be responsible for the expression of Weigle reactivation and X-ray reactivation.

    Genital herpes is one of the commonest sexually transmitted infections worldwide. Using the best available evidence, this guideline recommends strategies for diagnosis, management, and follow-up of the condition as well as for minimising transmission. Early recognition and initiation of therapy is key and may reduce the duration of illness or avoid hospitalisation with complications, including urinary retention, meningism, or severe systemic illness. The guideline covers a range of common clinical scenarios, such as recurrent genital herpes, infection during pregnancy, and co-infection with human immunodeficiency virus.

    Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

    Full Text Available Immunodeficient patients are at risk of developing extended or atypical herpes simplex virus infections, which can be easily misdiagnosed. We present the case of a 79-year-old, treatment-induced (oral corticosteroid, immunocompromised female with an extensive atypical herpes simplex virus infection. This patient presented with multiple erosions and vesicles on the trunk with a subacute onset. The clinical differential diagnosis was herpes simplex infection, herpes zoster infection, pemphigus vulgaris or bullous pemphigoid. Due to the atypical clinical presentation and negative Tzanck test, suspicion of viral infection was low. High-dose steroid treatment was initiated. Subsequent histopathology, however, showed a herpes simplex virus infection. After discontinuing steroid treatment and initiating antiviral treatment, the patient recovered within a week. Emphasis must be placed on the importance of clinical awareness of extended and clinically atypical herpes simplex infections in immunocompromised patients. A negative Tzanck test does not rule out the possibility of a herpes infection.

The aim of this study is to describe the characteristics of HSE and the factors influencing its outcome. Retrospective study of patients diagnosed with HSE in a tertiary care teaching hospital over a 15-year period. Diagnosis was based on a consistent clinical profile for HSE, plus either a PCR-positive CSF HSV study or consistent brain neuroimaging findings. Patients were divided into 2 groups according to the modified Rankin Scale: good outcome (Grades =3). Thirty-five patients were included. Mean age was 53.9 years. More than half presented febricula or fever, headache, disorientation, behavioral changes, decreased level of consciousness, or neurological deficit. CSF glucose concentration was normal in all patients and WBC count was normal in 8 (23%). PCR for HSV was positive in 92% and cranial MRI was suggestive of HSE in 100% of patients. Mortality was 8.6%. In relation to outcome, age (OR=1.079; 95% CI, 1.023-1.138) and serum albumin level at admission (OR=0.87; 95% CI, 0.794-0.954) were independent prognostic factors at discharge. At 6 months, days of fever after initiation of acyclovir therapy (OR=1.219; 95% CI, 1.046-1.422) and serum albumin level at admission (OR=0.917; 95% CI, 0.87-0.967) were independent prognostic factors. Normal brain MRI or detection of low CSF glucose concentration requires consideration of diagnoses other than HSE. Age, serum albumin level at admission, and days of fever after initiation of acyclovir therapy were independent prognostic factors of the disease.

  3. Increasing trends of herpes zoster in Australia.

    Directory of Open Access Journals (Sweden)

    Raina MacIntyre

    Full Text Available Increasing trends in incidence of herpes zoster (HZ have been reported in Australia and internationally. This may reflect the impact of childhood VZV vaccination programs introduced universally in Australia in late 2005. The objective of this study was to evaluate changes in incidence of HZ and PHN in Australia over time, and associated healthcare resource utilisation.Australian data on general practice (GP encounters for HZ, specific antiviral prescribing data from the pharmaceutical benefits scheme, emergency department presentations from the states of NSW and Victoria and national hospitalisation data for HZ were analysed for time trends using regression models. Two time periods (2000-2006 and 2006-2013 were compared which correspond broadly with the pre- and post- universal VZV vaccination period.All data sources showed increasing rates of HZ with age and over time. The GP database showed a significant annual increase in encounters for HZ of 2.5 per 100,000 between 1998 and 2013, and the rates of prescriptions for HZ increased by 4.2% per year between 2002 and 2012. In the 60+ population HZ incidence was estimated to increase from 11.9 to 15.4 per 1,000 persons using GP data or from 12.8 to 14.2 per 1,000 persons using prescription data (p<0.05, between the two periods. Hospitalisation data did not show the same increasing trend over time, except for the age group ≥80 years. Most emergency visits for HZ were not admitted, and showed significant increases over time.The burden of HZ in Australia is substantial, and continues to increase over time. This increase is seen both pre- and post-universal VZV vaccination in 2005, and is most prominent in the older population. The substantial burden of HZ, along with ageing of the Australian population and the importance of healthy ageing, warrants consideration of HZ vaccination for the elderly.

    Herpes zoster (HZ) is caused by VZV reactivation that is facilitated by a declined immunity against varicella-zoster virus (VZV), but also occurs in immunocompetent individuals. Cytomegalovirus (CMV) infection is associated with immunosenescence meaning that VZV-specific T-cells could be less responsive. This study aimed to determine whether CMV infection could be a risk factor for the development of HZ. CMV IgG serostatus was determined in stored serum samples from previously prospectively recruited ambulatory adult HZ patients in the UK (N = 223) in order to compare the results with those from UK population samples (N = 1545) by means of a logistic regression (controlling for age and gender). Furthermore, we compared the UK population CMV seroprevalence with those from population samples from other countries (from Belgium (N1 = 1741, N2 = 576), USA (N = 5572) and Australia (N = 2080)). Furthermore, CMV IgG titers could be compared between UK HZ patients and Belgium N2 population samples because the same experimental set-up for analysis was used. We found UK ambulatory HZ patients to have a higher CMV seroprevalence than UK population samples (OR 1.56 [1.11 2.19]). CMV IgG seropositivity was a significant risk factor for HZ in the UK (OR 3.06 [1.32 7.04]. Furthermore, high CMV IgG titers (exceeding the upper threshold) were less abundant in CMV-seropositive Belgian N2 population samples than in CMV-seropositive UK HZ patients (OR 0.51 [0.31 0.82]. We found CMV-seroprevalence to increase faster with age in the UK than in other countries (P < 0.05). We conclude that CMV IgG seropositivity is associated with HZ. This finding could add to the growing list of risk factors for HZ. PMID:25905443

  8. Herpes Simplex Virus Infections of the Central Nervous System.

    Science.gov (United States)

    Whitley, Richard J

    2015-12-01

    This article summarizes knowledge of herpes simplex virus (HSV) infections of the central nervous system (CNS). Disease pathogenesis, detection of DNA polymerase chain reaction (PCR) for diagnosis and prognosis, and approaches to therapy warrant consideration. HSV infection of the CNS is one of few treatable viral diseases. Clinical trials indicate that outcome following neonatal herpes simplex virus type 2 (HSV-2) infections of the CNS is significantly improved when 6 months of suppressive oral acyclovir therapy follows IV antiviral therapy. In contrast, herpes simplex virus type 1 (HSV-1) infections of the brain do not benefit from extended oral antiviral therapy. This implies a difference in disease pathogenesis between HSV-2 and HSV-1 infections of the brain. PCR detection of viral DNA in the CSF is the gold standard for diagnosis. Use of PCR is now being adopted as a basis for determining the duration of therapy in the newborn. HSV infections are among the most common encountered by humans; seropositivity occurs in 50% to 90% of adult populations. Herpes simplex encephalitis, however, is an uncommon result of this infection. Since no new antiviral drugs have been introduced in nearly 3 decades, much effort has focused on learning how to better use acyclovir and how to use existing databases to establish earlier diagnosis.

    Computed tomographic (CT) scans were obtained from eight infants and young children with herpes simplex virus encephalitis. In two cases the initial scan showed diffuse edematous changes as a mass effect without laterality. Unilateral localized low attenuation in the initial scan was evident 4 days after the onset in one patient, and high attenuation in the initial scan appeared on the 6th day in another patient, but in general, it was not possible to establish an early diagnosis of herpes simplex virus encephalitis from CT scan. In the longitudinal study the calcification with ventriculomegaly appeared in 3 of 5 survivors, and gyriform calcification in 2 of 3 patients, respectively. The appearance of multicystic encephalomalacia was evident in one patient 6 months after the onset of neonatal herpes simplex encephalitis. It is shown that the CT findings of neonates and young children with herpes simplex encephalitis are different from those of older children and adults, and the importance of longitudinal CT studies was stressed in clarifying the pathophysiology of the central nervous system involvement in survivors.

    The objective of this review was to collect reports of keratitis in association with herpes zoster virus (HZV) or varicella zoster virus (VZV) vaccines. HZV vaccination is intended for at-risk adult populations and VZV vaccination is intended for all pediatric patients. We reviewed the literature and reports of keratitis in association with herpes zoster or varicella vaccine from the National Registry of Drug-Induced Ocular Side Effects and the World Health Organization. Twenty-four cases of unilateral keratitis in association with VZV vaccines were collected from the adverse reaction databases and literature. In most cases, the onset of keratitis occurred within days of vaccination and resolved with topical steroid eye drops and oral acyclovir. Data suggest that keratitis in association with herpes zoster or varicella vaccine is rare, is usually self-limited or resolves with treatment. The mechanism may be the persistence of viral antigens in the cornea after VZV vaccination or herpes zoster ophthalmicus. This reaction is probable, given the plausible biological mechanism, the temporal relationship between vaccination and keratitis, and overall patterns of presentation after vaccination.

    Herpes zoster infection involving the sacral dermatomes has been associated with bladder dysfunction and, although rarely, with acute urinary retention. Less than 150 cases have been reported in the literature. After reviewing our institute's chart records covering a period of time dating from 1991 to 2001, we found that three of our patients had developed acute urinary retention following herpes zoster skin lesions of the S2-4 dermatomes. Herein we report our findings. These three patients had previously been found to have normal voiding status. However, at the time of complaint urodynamic studies revealed detrusor areflexia or detrusor hyporeflexia with decreased sensation of bladder filling. After micturation recovery, repeat urodynamic studies revealed detrusor pressure and bladder sensation recovery. After one to six weeks of treatment, all three patients could void spontaneously without catheterization. We found that, when treated with antiviral medication, supportive analgesics, and temporary urinary drainage, which included urethral catheterization and suprapubic cystostomy, acute urinary retention associated with herpes zoster has a generally favorable prognosis. In other words, we found that in spite of its rarity, herpes zoster induced neuropathic bladder dysfunction is reversible when treated appropriately.

    Voiding dysfunction is a rare but important complication of lumbo-sacral herpes zoster. Although the symptoms are transient, the clinical impact on immunocompromised patients cannot be overlooked. To clarify the time course of voiding dysfunction in herpes zoster, 13 herpes zoster patients with voiding dysfunction were retrospectively analyzed. Of 13 patients, 12 had background disease, and six of these were hematopoietic malignancies; four of these patients were hematopoietic stem cell transplant (HSCT) recipients. Ten patients had sacral lesions, two had lumbar, and one had thoracic lesions. Interestingly, patients with severe rash, or with hematopoietic malignancy had later onset of urinary retention than did patients with mild skin symptoms (Mann-Whitney U analysis, P = 0.053) or with other background disease (P = 0.0082). Patients with severe skin rash also had longer durations (P = 0.035). In one case, acute urinary retention occurred as late as 19 days after the onset of skin rash. In immune compromised subjects, attention should be paid to patients with herpes zoster in the lumbo-sacral area for late onset of acute urinary retention even after the resolution of skin symptoms.

    To monitor the incidence of neonatal herpes in The Netherlands between 2006 and 2011, as well as the adherence to the rather conservative Dutch prevention policy. Questionnaires were sent to all virology laboratories (n = 44), gynaecology and paediatrics departments of all hospitals in The Netherlands (n = 89). Questionnaires for the laboratories pertained to rates of proven cases of neonatal herpes; for the gynaecologists and paediatricians it pertained to rates of genital herpes during pregnancy and neonatal herpes, and their policy. For gynaecologists this concerned the risk of herpes simplex virus transmission in case of primary genital herpes during pregnancy or labour; for paediatricians it concerned the diagnostic policy in a neonate suspected of neonatal herpes. For the period 2006-2011 38 cases of neonatal herpes were reported, yielding an incidence of 4.7 per 100,000 births. The estimated annual number of pregnant women with primary or recurrent genital herpes was 278. Of the responding gynaecologists and paediatricians, only 59% and up to 39%, respectively, reported a policy in accordance with the national guideline. The incidence of neonatal herpes in The Netherlands seems to have increased in the period 2006-2011. Combined with suboptimal guideline adherence this warrants strategies to improve awareness and subsequent adherence.

    1996-09-01

    The purpose of this study was to ascertain how accurate the general public was at diagnosing the condition of recrudescent herpes labialis. An advertisement was placed in a local newspaper inviting patients to attend the Oral Medicine Clinic as soon as they thought they developed the clinically evident stage of herpes labialis. At the clinic, patients were examined to confirm the clinical presence of herpes labialis and also had a swab of the lesion(s) taken for virus culture. Virus culture was by the HEP-2 culture technique capable of detecting both herpes simplex Type 1 and herpes simplex Type 2. Patients also completed a detailed questionnaire concerning their knowledge of herpes labialis. In total, 41 patients attended for screening. The findings were that all patients had clinical herpes labialis, and herpes simplex virus was isolated in 96% of cases. In contrast, in only about 50% of cases were patients aware that their herpes labialis was caused by a virus. The general public are very good at recognizing herpes labialis lesions but need to be given more information about their infectivity.

  12. Recurrent genital herpes treatments and their impact on quality of life.

    2003-01-01

    Herpes genitalis is one of the most common viral sexually transmitted diseases in the world, with an estimated seroprevalence in the US of greater than 20%. Two viruses of the same family cause herpes genitalis: herpes simplex virus 1 and 2. After the resolution of primary infection, the virus persists in the nerve roots of the sacral plexus, often causing recurrent (though generally less severe) outbreaks. These outbreaks, as well as the infectious potential to the patient's sexual partners, results in significant psychological stress on the patient, and has a tremendous negative impact on QOL. Current treatment modalities may result in a reduction in the number of outbreaks and viral shedding, but no cure exists. Although studies have clearly demonstrated the negative impact of recurrent genital herpes on QOL, an assessment scale specific to herpes was not developed until recently. Earlier studies indicated that patients did not perceive a significant benefit from episodic treatment with antivirals, but studies using the Recurrent Genital Herpes Quality of Life Questionnaire (RGHQoL) have now demonstrated that suppressive antiviral therapy improves quality of life in patients with frequent recurrences of genital herpes. However, not all patients with recurrent genital herpes need suppressive therapy, and proposed factors to consider include frequency of recurrence, physical and psychological distress caused by recurrences, and the potential for transmission to the patient's sexual partner. Newer therapeutic modalities, including the topical immune response modifier resiquimod and herpes vaccines, may eventually be shown to further decrease the psychological morbidity of recurrent genital herpes.

    No formal epidemiological research based on systematic analysis has focused on the relationship between herpes zoster and immunodeficiency virus (HIV) infection in Taiwan. Our aim was to explore whether herpes zoster is an early manifestation of undiagnosed human HIV infection in Taiwan. This was a retrospective cohort study using the database of the Taiwan National Health Insurance Program. A total of 35,892 individuals aged ≤ 84 years with newly diagnosed herpes zoster from 1998 to 2010 were assigned to the herpes zoster group, whereas 143,568 sex-matched and age-matched, randomly selected individuals without herpes zoster served as the non-herpes zoster group. The incidence of HIV diagnosis at the end of 2011 was estimated in both groups. The multivariable Cox proportional hazards regression model was used to estimate the hazard ratio and 95% confidence interval (CI) for risk of HIV diagnosis associated with herpes zoster and other comorbidities including drug dependence and venereal diseases. The overall incidence of HIV diagnosis was 4.19-fold greater in the herpes zoster group than that in the non-herpes zoster group (3.33 per 10,000 person-years vs. 0.80 per 10,000 person-years, 95% CI 4.04-4.35). The multivariable Cox proportional hazards regression analysis revealed that the adjusted hazard ratio of HIV diagnosis was 4.37 (95% CI 3.10-6.15) for individuals with herpes zoster and without comorbidities, as compared with individuals without herpes zoster and without comorbidities. Herpes zoster is associated with HIV diagnosis. Patients who have risk behaviors of HIV infection should receive regular surveillance for undiagnosed HIV infection when they present with herpes zoster. Copyright © 2015. Published by Elsevier B.V.

    Full Text Available Accurate identification of persons with genital herpes is necessary for optimal patient management and prevention of transmission. Because of inherent inaccuracies, clinical diagnosis of genital herpes should be confirmed by laboratory testing for the causative agents herpes simplex virus type 1 (HSV-1 and HSV type 2 (HSV-2. Further identification of the HSV type is valuable for counselling on the natural history of infection and risk of transmission. Laboratory methods include antigen detection, culture, polymerase chain reaction (PCR and conventional and type-specific serology (TSS. PCR has, by far, the greater sensitivity and should be the test of choice for symptomatic cases. HSV-2 TSS is indicated for patients with genital lesions in whom antigen detection, culture or PCR fail to detect HSV, and for patients who are asymptomatic but have a history suggestive of genital herpes. HSV-2 TSS is further indicated for patients infected with HIV. HSV-2 TSS along with HSV-1 TSS may be considered, as appropriate, in evaluating infection and/or immune status in couples discordant for genital herpes, women who develop their first clinical episode of genital herpes during pregnancy, asymptomatic pregnant women whose partners have a history of genital herpes or HIV infection, and women contemplating pregnancy or considering sexual partnership with those with a history of genital herpes. The above should be performed in conjunction with counselling of infected persons and their sex partners.

    The US Advisory Committee on Immunization Practices has recently recommended a new vaccine against herpes zoster (shingles) for routine use in adults aged > or =60 years. However, estimates of the cost effectiveness of this vaccine vary widely, in part because of gaps in the data on the value of preventing herpes zoster. Our aims were to (i) generate comprehensive information on the value of preventing a range of outcomes of herpes zoster; (ii) compare these values among community members and patients with shingles and post-herpetic neuralgia (PHN); and (iii) identify clinical and demographic characteristics that explain the variation in these values. Community members drawn from a nationally representative survey research panel (n = 527) completed an Internet-based survey using time trade-off and willingness-to-pay questions to value a series of scenarios that described cases of herpes zoster with varying pain intensities (on a scale of 0 to 10, where 0 represents no pain and 10 represents the worst imaginable pain) and duration (30 days to 1 year). Patients with shingles (n = 382) or PHN (n = 137) [defined as having symptoms for > or =90 days] from two large healthcare systems completed telephone interviews with similar questions to the Internet-based survey and also answered questions about their current experience with herpes zoster. We constructed generalized linear mixed models to evaluate the associations between demographic and clinical characteristics, the length and intensity of the health states and time trade-off and willingness-to-pay values. In time trade-off questions, community members offered a mean of 89 (95% CI 24, 182) discounted days to avoid the least severe scenario (pain level of 3 for 1 month) and a mean of 162 (95% CI 88, 259) discounted days to avoid the most severe scenario (pain level of 8 for 12 months). Compared with patients with shingles, community members traded more days to avoid low-severity scenarios but similar numbers of days

    A rapid indirect micro-immunofluorescence test capable of detecting and differentiating type-specific antibodies to herpes simplex virus is described. The test proved highly sensitive and, in 80 patients with active herpes ocular infection, antibody was detected in 94%. No anti-herpes antibody was detected in a control group of 20 patients with adenovirus infections. Testing of animal sera prepared against herpes simplex virus types 1 and 2 and of human sera from cases of ocular and genital herpes infections showed that the test can differentiate antibodies to the infecting serotypes. Specimens of whole blood, taken by fingerprick, and eye secretions, both collected on cellulose sponges, could be tested by indirect micro-immunofluorescence. Anti-herpes IgG, IgM, and IgA can also be detected.

    Herpes simplex virus encephalitis can manifest as a range of clinical presentations including classic adult, neonatal, and biphasic chronic-granulomatous herpes encephalitis. We report an infant with granulomatous herpes simplex virus type 2 encephalitis with a subacute course and multicystic encephalopathy. A 2-month-old girl presented with lethargy and hypothermia. Computed tomography scan of the head showed multicystic encephalopathy and calcifications. Cerebrospinal fluid analysis by polymerase chain reaction testing for herpes simplex virus 1 and 2, enterovirus, and cytomegalovirus was negative. Normal cerebrospinal fluid interferon-α levels argued against Aicardi-Goutières syndrome. The patient died 2 weeks after presentation. At autopsy, multicystic encephalopathy was confirmed with bilateral gliosis, granulomatous inflammation with multinucleated giant cells, and calcifications. Bilateral healing necrotizing retinitis suggested a viral etiology, but retina and brain were free of viral inclusions and immunohistochemically negative for herpes simplex virus-2 and cytomegalovirus. However, polymerase chain reaction analysis showed herpes simplex virus-2 DNA in four cerebral paraffin blocks. Subsequent repeat testing of the initial cerebrospinal fluid sample using a different polymerase chain reaction assay was weakly positive for herpes simplex virus-2 DNA. Granulomatous herpes simplex virus encephalitis in infants can present with subacute course and result in multicystic encephalopathy with mineralization and minimal cerebrospinal fluid herpes simplex virus DNA load. Infectious etiologies should be carefully investigated in the differential diagnosis of multicystic encephalopathy with mineralization, in particular if multinucleated giant cells are present.

    Decompressive craniectomy in pediatric central nervous infections with refractory intracranial hypertension is less commonly practiced. We describe improved outcome of decompressive craniectomy in a 7-year-old boy with severe herpes simplex encephalitis and medically refractory intracranial hypertension, along with a brief review of the literature. Timely recognition of refractory intracranial hypertension and surgical decompression in children with herpes simplex encephalitis can be life-saving. Additionally, strokelike atypical presentations are being increasingly recognized in children with herpes simplex encephalitis and should not take one away from the underlying herpes simplex encephalitis. © The Author(s) 2014.

    Full Text Available Infection with genital herpes simplex virus (HSV remains a common viral sexually transmitted disease, often subclinical and a major worldwide problem of women of reproductive age group. Herpes cervicitis is an unusual presentation of Herpes simplex virus infection in females. The finding of herpes cervicitis on routine pap smear of an asymptomatic woman on Intrauterine contraceptive device still further supports the need for increased awareness on the possibility of Herpes simplex virus infection among women, particularly those on Intrauterine contraceptive device. The index case is a 28 years old Nigerian female who was referred to our Special Treatment Clinic on account of an abnormal pap smear cytology which was in keeping with Herpes cervicitis. There was no history of genital ulcer in this patient; however ELISA for HSV 2 IgM was positive in her. We therefore describe a case of herpes cervicitis in an asymptomatic woman on intrauterine contraceptive device. This case highlights to clinicians the need to be aware of the possibility of this association and to carry out relevant investigations so as to identify and treat these patients appropriately. Therefore, there is a need to put in place adequate public health intervention strategy to prevent genital herpes in women of reproductive age group with a view to preventing the possibility of congenital herpes in subsequent pregnancy.

    Lysates of radiolabeled explants from four human trigeminal ganglia were immunoprecipitated with antibodies to varicella-zoster virus (VZV) and to herpes simplex virus. Both herpes simplex virus- and VZV-specific proteins were detected in lysates of all four ganglia. Absence of reactivity in ganglion explants with monoclonal antibodies suggested that herpes simplex virus and VZV were not reactivated during the culture period. In situ hybridization studies demonstrated the presence of RNA transcripts from the VZV immediate early gene 63. This approach to the detection of herpes simplex virus and VZV expression in human ganglia should facilitate analysis of viral RNA and proteins in human sensory ganglia

    AIM: To report a case of superior orbital fissure syndrome (SOFS) in a patient with herpes zoster ophthalmicus (HZO). MATERIALS AND METHODS: A case report. RESULTS: A 71-year-old male with HZO presented acutely to accident and emergency complaining of right vision loss, double vision and drowsiness. The right visual acuity was counting fingers. There was no relative afferent pupillary defect. He had interstitial keratitis, ptosis, proptosis and total ophthalmoplaegia. The signs indicated HZO complicated by SOFS. Brain imaging and lumbar puncture confirmed the diagnosis of varicella zoster encephalitis. Systemic acyclovir and prednisolone led to recovery of visual acuity and ocular motility in addition to resolution of his proptosis and ptosis. CONCLUSION: SOFS is a rare complication of herpes zoster infection. With the appropriate treatment and follow-up, patients may be reassured that recovery of their visual acuity and ocular motility will occur.

    Herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) are highly prevalent viruses capable of establishing lifelong infection. Genital herpes in women of childbearing age represents a major risk for mother-to-child transmission (MTCT) of HSV infection, with primary and first-episode genital HSV infections posing the highest risk. The advent of antiviral therapy with parenteral acyclovir has led to significant improvement in neonatal HSV disease mortality. Further studies are needed to improve the clinician's ability to identify infants at increased risk for HSV infection and prevent MTCT, and to develop novel antiviral agents with increased efficacy in infants with HSV infection.

    2016-01-01

    abstract More than 50% of the U.S. population is infected with herpes simplex virus type-I (HSV-1) and global infectious estimates are nearly 90%. HSV-1 is normally seen as a harmless virus but debilitating diseases can arise, including encephalitis and ocular diseases. HSV-1 is unique in that it can undermine host defenses and establish lifelong infection in neurons. Viral reactivation from latency may allow HSV-1 to lay siege to the brain (Herpes encephalitis). Recent advances maintain that HSV-1 proteins act to suppress and/or control the lysosome-dependent degradation pathway of macroautophagy (hereafter autophagy) and consequently, in neurons, may be coupled with the advancement of HSV-1-associated pathogenesis. Furthermore, increasing evidence suggests that HSV-1 infection may constitute a gradual risk factor for neurodegenerative disorders. The relationship between HSV-1 infection and autophagy manipulation combined with neuropathogenesis may be intimately intertwined demanding further investigation. PMID:26934628

    2016-01-01

    Full Text Available Herpes simplex esophagitis (HSE is commonly identified in immunosuppressed patients. It is rare among immunocompetent patients and almost all of the reported cases are due to HSV-1 infection. HSV-2 esophagitis is extremely rare. We report the case of a young immunocompetent male who presented with dysphagia, odynophagia, and epigastric pain. Endoscopy showed multitudes of white nummular lesions in the distal esophagus initially suspected to be candida esophagitis. However, classic histopathological findings of multinucleated giant cells with eosinophilic intranuclear inclusions and positive HSV-2 IgM confirmed the diagnosis of HSV-2 esophagitis. The patient rapidly responded to acyclovir treatment. Although HSV-2 is predominantly associated with genital herpes, it can cause infections in other parts of the body previously attributed to only HSV-1 infection.

    Disclosure is often a challenge for individuals living with genital herpes. This study explores determinants of genital herpes disclosure with one's most recent sexual partner using an online questionnaire (n = 93). The majority of participants reported (80.4%) disclosure. Among non-disclosers, fear of negative partner reactions was the primary reason for non-disclosure. Age, relationship commitment, time in relationship, and expectations of partner's reaction were statistically significant predictors at the bivariate level. Reaction expectations and relationship commitment remained significant in the multivariate logistic regression model. Findings indicate that future disclosure research should focus on relationship context and managing negative expectations to increase disclosure. © The Author(s) 2015.

    2016-04-01

    Immunotherapeutic vaccines have emerged as a novel treatment modality for genital herpes, a sexually transmitted disease mainly caused by herpes simplex virus type 2. The approaches to identify potential vaccine antigens have evolved from classic virus attenuation and characterization of antibody and T cell responses in exposed, but seronegative individuals, to systematic screens for novel T cell antigens. Combined with implementation of novel vaccine concepts revolving around immune evasion and local recruitment of immune effectors, the development of a safe and effective therapeutic vaccine is within reach. Here, we describe the vaccine approaches that currently show promise at clinical and pre-clinical stages and link them to the evolving scientific strategies that led to their identification.

    1976-01-01

    Herpes simplex virus is a frequent cause of recurrent ocular, oral, genital or cutaneous eruptions in man. Lesions are highly localized and tend to recur at the same site. Among the most consistent factors provoking recurrence is root section of the trigeminal nerve. Clinical and experimental data suggest that herpes simplex virus is commonly resident within the trigeminal ganglia of man, where it may be responsible for recurrent oral or lip lesions, and is less frequently a resident of the second or third sacral ganglia where it might be responsible for genital eruptions. Generally, the trigeminal virus is type 1 and the sacral virus is type 2; the virus is only rarely recoverable from other sensory ganglia. Factors provoking the reactivation from the virus' latent site and the mechanism for reactivation remain largely unknown. Further study is needed to understand the behavior of HSV and other viruses in nervous system tissue.

    Full Text Available Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. Case report: We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Conclusion: Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

    Genital herpes is a sexually transmitted disease. After the primary infection, the virus establishes a life-long latency in the sacral dorsal root ganglia. Recurrences may occur at an unpredictable rate. The clinical signs are not always easy to recognize and viral identification techniques may be helpful such as immunohistochemistry and in situ hybridization on Tzanck smears and muco-cutaneous biopsies. The treatment of genital herpes can follow one of three strategies using antiviral drugs, non-specific immunomodulators, and vaccination. The new oral antiviral drugs decrease the severity of clinical manifestations without, however, providing a definitive cure. In this article recent knowledge about the clinical aspects, differential diagnosis, diagnostic methods, treatment options and management is reviewed.

Our patient was initially admitted to a neighborhood hospital because of nausea and loss of appetite of 10 days' duration. The day after hospitalization, she developed skin vesicles along the first division of the trigeminal nerve, with severe lid swelling and conjunctival injection. On suspicion of meningoencephalitis caused by varicella zoster virus, antiviral therapy with vidarabine and betamethasone was started. Seventeen days later, complete ptosis and ophthalmoplegia developed in the right eye. The light reflex in the right eye was absent and anisocoria was present, with the right pupil larger than the left. Fat-suppressed enhanced T1-weighted magnetic resonance images showed high intensity areas in the muscle cone, cavernous sinus, and orbital optic nerve sheath. Our patient was diagnosed with orbital apex syndrome, and because of skin vesicles in the first division of the trigeminal nerve, the orbital apex syndrome was considered to be caused by herpes zoster ophthalmicus. After the patient was transferred to our hospital, prednisolone 60 mg and vidarabine antiviral therapy was started, and fever and headaches disappeared five days later. The ophthalmoplegia and optic neuritis, but not the anisocoria, gradually resolved during tapering of oral therapy. From the clinical findings and course, the cause of the orbital apex syndrome was most likely invasion of the orbital apex and cavernous sinus by the herpes virus through the trigeminal nerve ganglia.Keywords: varicella zoster virus, orbital apex syndrome, herpes zoster ophthalmicus, complete ophthalmoplegia

    Varicella is a self-limiting and relatively mild disease of childhood, although it is frequently more severe and complicated among the immunocompromised rheumatology patients on immunomodulator therapies. In addition, future reactivation of the dormant virus in dorsal root ganglia may cause herpes zoster infection, which can be very debilitating. In this manuscript, we discuss the nature of this infection along with its potential vaccine especially among rheumatology patients.

    Antarctica is a useful analog for spaceflight, as both environments are remote, isolated, and with limited resources. While previous studies have demonstrated increased asymptomatic viral shedding in both the Antarctic and spaceflight environments, clinical manifestations of reactivated viral disease have been less frequently identified. We sought to identify the incidence of clinical herpes zoster from viral reactivation in the Antarctic winter-over population. Medical records from the 2014 winter season were reviewed for the incidence of zoster in U.S. Antarctic personnel and then compared to the age-matched U.S. Five cases of clinical herpes zoster occurred in the Antarctic Station population of 204 persons, for an incidence of 33.3 per 1000 person-years vs. 3.2 per 1000 person-years in the general population. Four cases were in persons under age 40, yielding an incidence of 106.7 per 1000 person-years in persons ages 30-39 compared to an incidence of 2.0 per 1000 person-years in the same U.S. age group. Immune suppression due to the stressful Antarctic environment may have contributed to the increased incidence of herpes zoster in U.S. Antarctic personnel during the winter of 2014. Working and living in isolated, confined, and extreme environments can cause immune suppression, reactivating latent viruses and increasing viral shedding and symptomatic disease. Such changes have been observed in other austere environments, including spaceflight, suggesting that clinical manifestations of viral reactivation may be seen in future spaceflight.Reyes DP, Brinley AA, Blue RS, Gruschkus SK, Allen AT, Parazynski SE.

    A case of herpes simplex encephalitis was examined by computer tomography. Both cerebral hemispheres showed contrast enhancement of the gyri. The cause of this is considered. The increased contrast medium accumulation in the affected areas is probably due to the marked vascular proliferation which can be demonstrated anatomically, and to the rapid escape of contrast from the capillaries into the interstitial spaces. The findings of other authors, which differ somewhat, are discussed. (orig.) [de

    Herpes zoster ophthalmicus (HZO) is a clinical manifestation of the reactivation of latent varicella zoster virus (VZV) infection and is more common in people with diminished cell-mediated immunity. Lesions and pain correspond to the affected dermatomes, mostly in first or second trigeminal branch and progress from maculae, papules to vesicles and form pustules, and crusts. Complications are cutaneous, visceral, neurological, ocular, but the most debilitating is post-herpetic neuralgia. Herpes zoster ophthalmicus may affect all the ophthalmic structures, but most severe eye-threatening complications are panuveitis, acute retinal necrosis (ARN) and progressive outer retinal necrosis (PORN) as well. Antiviral medications remain the primary therapy, mainly useful in preventing ocular involvement when begun within 72 hours after the onset of the rash. Timely diagnosis and management of HZO are critical in limiting visual morbidity. Vaccine in adults over 60 was found to be highly effective to boost waning immunity what reduces both the burden of herpes zoster (HZ) disease and the incidence of post-herpetic neuralgia (PHN).

    Besides overcoming physical constraints, such as extreme temperatures, reduced humidity, elevated pressure, and natural predators, human pathogens further need to overcome an arsenal of antimicrobial components evolved by the host to limit infection, replication and optimally, reinfection. Herpes simplex virus-1 (HSV-1) and herpes simplex virus-2 (HSV-2) infect humans at a high frequency and persist within the host for life by establishing latency in neurons. To gain access to these cells, herpes simplex viruses (HSVs) must replicate and block immediate host antiviral responses elicited by epithelial cells and innate immune components early after infection. During these processes, infected and noninfected neighboring cells, as well as tissue-resident and patrolling immune cells, will sense viral components and cell-associated danger signals and secrete soluble mediators. While type-I interferons aim at limiting virus spread, cytokines and chemokines will modulate resident and incoming immune cells. In this paper, we discuss recent findings relative to the early steps taking place during HSV infection and replication. Further, we discuss how HSVs evade detection by host cells and the molecular mechanisms evolved by these viruses to circumvent early antiviral mechanisms, ultimately leading to neuron infection and the establishment of latency.

    Full Text Available Herpes simplex infection is characterized by acute or subacute infection, often followed by a chronic carrier state. Consecutive recurrences may flare up if immunocompromise occurs. Herpes simplex associated esophagitis or duodenal ulcer have been reported in immunocompromised patients due to neoplasm, HIV/AIDS or therapeutically induced immune deficiency. Here we report the case of an HSV-DNA seronegative patient who developed grade III dysphagia 13 days after allogeneic liver transplantation. Endoscopy revealed an esophageal-gastric ulcer, and biopsy histopathology showed a distinct fibroplastic and capillary ulcer pattern highly suspicious for viral infection. Immunohistochemistry staining revealed a distinct nuclear positive anti-HSV reaction. Antiviral therapy with acyclovir and high-dose PPI led to a complete revision of clinical symptoms within 48 h. Repeat control endoscopy after 7 days showed complete healing of the former ulcer site at the gastroesophageal junction. Although the incidence of post-transplantation Herpes simplex induced gastroesophageal disease is low, the viral HSV ulcer may be included into a differential diagnosis if dysphagia occurs after transplantation even if HSV-DNA PCR is negative.

    Full Text Available Herpes zoster (HZ occurs in older ages with activation of varicella-zoster virus (VZV which persists in a dormant phase within the dorsal root ganglia. The incidence of HZ in immunosuppressed patients is 20-100 times higher and the clinical progress is more severe than in immunocompetent individuals. A 48-year-old man who had been diagnosed with acute myelocytic leukemia type M3 and had been treated with immunosuppressive agents was admitted to our clinic. The patient was clinically diagnosed as having HZ. He was treated with acyclovir 800 mg five times daily for 7 days. In the consecutive three months, he attended our clinic again with similar complaints. The left cervical (C5, C6 dermatomes were involved at the fourth attack of HZ. Multinucleated giant cells were determined on the Tzanck smear. VZV DNA was detected by polymerase chain reaction (PCR. Treatment with valacyclovir 1 g three times daily for 14 days was prescribed and then, prophylactic treatment with valacyclovir 500 mg two times a day was administered. Although immunosuppressive treatment was continued, no new attacks of herpes zoster occurred. We think that prophylactic antiviral therapy should be initiated in immunosuppressive individuals who have recurrent herpes zoster attacks.

    A 24-year-old immune-competent woman was admitted to hospital with a three-day history of fever and headache. On examination bilateral facial nerve palsy, lumbosacral radicular pain, reduced sacral sensibility and urinary retention were found. Open perianal lesions were suspect for genital herpes. The symptoms were compatible with a meningoradiculitis including a sacral polyradiculitis. On testing, cerebrospinal fluid was found to be abnormal with a lymphocytic cell reaction. Polymerase chain reaction (PCR) of cerebrospinal fluid and of the perianal lesions was positive for herpes simplex virus type 2 (HSV-2). An MRI scan showed colouration of part of the cauda equina. The patient was treated by intravenous injections of acyclovir 10 mg/kg t.i.d. for 21 days, after which she completely recovered. HSV-2 infection of the nervous system can cause lymphocytic, and sometimes recurrent meningitis as well as sacral polyradiculitis. It may also occur without any symptomatic genital herpes infection. A positive result from a PCR test of the cerebrospinal fluid confirms this diagnosis. Treatment with acyclovir should be started as soon as possible.

  15. CXCL11 production in cerebrospinal fluid distinguishes herpes simplex meningitis from herpes simplex encephalitis.

    The closely related herpes simplex viruses 1 and 2 can cause inflammations of the central nervous system (CNS), where type 1 most often manifest as encephalitis (HSE), and type 2 as meningitis (HSM). HSE is associated with severe neurological complications, while HSM is benign in adults. We proposed that studying the chemokine and cytokine production in cerebrospinal fluid (CSF) and serum could indicate why two closely related viruses exhibit different severity of their accompanied CNS inflammation. Secretion patterns of 30 chemokines and 10 cytokines in CSF of adult patients with acute HSE (n = 14) and HSM (n = 20) in the initial stage of disease were analyzed and compared to control subjects without viral central nervous system infections and to levels in serum. Most measured chemokines and cytokines increased in CSF of HSE and HSM patients. Overall, the CSF chemokine levels were higher in CSF of HSM patients compared to HSE patients. However, only five chemokines reached levels in the CSF that exceeded those in serum facilitating a positive CSF-serum chemokine gradient. Of these, CXCL8, CXCL9, and CXCL10 were present at high levels both in HSE and HSM whereas CXCL11 and CCL8 were present in HSM alone. Several chemokines were also elevated in serum of HSE patients but only one in HSM patients. No chemokine in- or efflux between CSF and serum was indicated as the levels of chemokines in CSF and serum did not correlate. We show that HSM is associated with a stronger and more diverse inflammatory response in the CNS compared to HSE in the initial stage of disease. The chemokine patterns were distinguished by the exclusive local CNS production of CXCL11 and CCL8 in HSM. Inflammation in HSM appears to be restricted to the CNS whereas HSE also was associated with systemic inflammation.

    Herpes simplex encephalitis is a severe neurological condition, whose outcome is improved if treated early with acyclovir. Post-herpes simplex encephalitis with acute chorea has rarely been reported. We report on two observations of children presenting with post-herpes simplex encephalitis with acute chorea, related to two different pathophysiological mechanisms. The first one is an 11-month-old girl developing relapsing herpes simplex encephalitis with chorea due to resumption of viral replication. The second one is a 2-year-old boy with relapsing post-herpes simplex encephalitis acute chorea caused by an immunoinflammatory mechanism. We discuss the different neurological presentations of herpetic relapses, notably those presenting with movement disorders, as well as their clinical, paraclinical, physiopathological, and therapeutic aspects. Post-herpes simplex encephalitis with acute chorea may involve two mechanisms: resumption of viral replication or an immunoinflammatory mechanism. Treatment of post-herpes simplex encephalitis with acute chorea depends on the underlying mechanism, while prevention is based on antiviral treatment of herpes simplex encephalitis with acyclovir at the dose of 20mg/kg/8h for 21 days.

    Full Text Available Among persistent intracellular agents, a group of herpesviruses occupies the leading place after the prevalence. The World Health Organization (WHO warns the international community of the danger of latent herpes infection pandemic. According to the WHO, 70 to 90 % of the world population is infected with one or more types of herpes virus, and in 50 % of them, due to the absence of stable immunity, disease relapses occur annually. The family of herpes viruses found in humans includes herpes simplex virus type 1 and 2, Zoster virus, cytomegalovirus, Epstein-Barr virus, human herpes type 6, 7, 8. Thus, in the pathogenesis of herpes infection type 1 and 2, there are four main phases: the penetration of the epithelial cells → penetration into the nerve endings and paravertebral ganglia → elimination of the virus from tissues and organs → reactivation of herpes simplex virus and moving it to the port of infection. Herpetic and cytomegalovirus infection that belongs to the group of TORCH infections is the most common cause fetal infection, which can lead to the birth of a child with disabilities. Herpesvirus infections are considered as a group of infections associated with human immunodeficiency syndrome, and is a common cause of damage to the central nervous system and internal organs in patients with secondary immunodeficiency. Almost all known now human herpesviruses can cause damage to the nervous system. In this regard, herpes infections have become one of the leading medical and social problems and acquire national importance.

    Herpes simplex virus types 1 and 2 are the main cause of genital ulcers worldwide. Although herpes simplex virus type 2 is the major cause of genital lesions, herpes simplex virus type 1 accounts for half of new cases in developed countries. Herpes simplex virus type 2 seroprevalence rises with sexual activity from adolescence through adulthood. Slovenian data in a high-risk population shows 16% seroprevalence of HSV-2. HSV-1 and HSV-2 DNA in genital swabs was detected in 19% and 20.7%, respectively. In most cases, genital herpes is asymptomatic. Primary genital infection with herpes simplex virus types 1 and 2 can be manifested by a severe clinical picture, involving the vesicular skin and mucosal changes and ulcerative lesions of the vulva, vagina, and cervix in women and in the genital region in men. Direct methods of viral genome detection are recommended in the acute stage of primary and recurrent infections when manifest ulcers or lesions are evident. Serological testing is recommended as an aid in diagnosing genital herpes in patients with reinfection in atypical or already healed lesions. When herpes lesions are present, all sexual activities should be avoided to prevent transmission of infection. Antiviral drugs can reduce viral shedding and thus reduce the risk of sexual transmission of the virus.

    The pathogenesis of herpes zoster is closely linked to reduced varicella-zoster virus-specific cell-mediated immunity. However, little is known about the interplay between natural killer cells and psychological stress in the pathogenesis of herpes zoster. This study aimed to investigate possible associations among natural killer cells, T cells and psychological stress in herpes zoster. Interferon-gamma secretion from natural killer cell, psychological stress events, stress cognition scale scores and cytomegalovirus-specific cell-mediated immunity were compared between 44 patients with herpes zoster and 44 age- and gender-matched control subjects. A significantly lower median level of interferon-gamma secreted by natural killer cells was observed in patients with a recent diagnosis of herpes zoster than in control subjects (582.7 pg/ml vs. 1783 pg/ml; P = 0.004), whereas cytomegalovirus-specific cell-mediated immunity was not associated with herpes zoster. Psychological stress events and high stress cognition scale scores were significantly associated in patients with herpes zoster (Pherpes zoster display reduced interferon-gamma secretion from natural killer cells and frequent previous psychological stress events compared with controls. However, reduced natural killer cell activity is not an immunological mediator between psychological stress and herpes zoster.

    Based on the fact that the gluteal herpes may constitute the clinical expression of the reactivation of a Herpes simplex virus latent at the sacral lymph node, we investigated a group of women who were carriers of gluteal herpetic infection, the characteristics of the infection, the virus type principally associated to it, and its possible relation with the genital herpes. Forty one women with gluteal herpes verified by virologic laboratory were studied. 75.7% of these women had had in addition to this herpetic infection in other places, mainly genital, with an average of 7.2 of recurrent episodes per year, (range: 1 to 18 episodes yearly). 78% of the isolated virus was typified as HSV-2 by the use of monoclonal antibodies. It is stand out the importance of considering the background of gluteal herpes as causative of classification of herpetic high risk.

    The aim of this study was to evaluate the use of RNA interference to inhibit herpes simplex virus type-1 replication in vitro. For herpes simplex virus type-1 gene silencing, three different small interfering RNAs (siRNAs) targeting the herpes simplex virus type-1 UL39 gene (sequence si-UL 39-1, si-UL 39-2, and si-UL 39-3) were used, which encode the large subunit of ribonucleotide reductase, an essential enzyme for DNA synthesis. Herpes simplex virus type-1 was isolated from saliva samples and mucocutaneous lesions from infected patients. All mucocutaneous lesions' samples were positive for herpes simplex virus type-1 by real-time PCR and by virus isolation; all herpes simplex virus type-1 from saliva samples were positive by real-time PCR and 50% were positive by virus isolation. The levels of herpes simplex virus type-1 DNA remaining after siRNA treatment were assessed by real-time PCR, whose results demonstrated that the effect of siRNAs on gene expression depends on siRNA concentration. The three siRNA sequences used were able to inhibit viral replication, assessed by real-time PCR and plaque assays and among them, the sequence si-UL 39-1 was the most effective. This sequence inhibited 99% of herpes simplex virus type-1 replication. The results demonstrate that silencing herpes simplex virus type-1 UL39 expression by siRNAs effectively inhibits herpes simplex virus type-1 replication, suggesting that siRNA based antiviral strategy may be a potential therapeutic alternative.

    Some infectious diseases have been found to be associated with cognitive impairment and dementia. However, the relationship between herpes zoster and dementia has received little attention. This study aimed to investigate this association as well as associations of antiviral treatments for herpes zoster and incident dementia using a large national sample. Cases were identified from the Taiwan National Health Insurance Research Database with a new diagnosis of herpes zoster (ICD-9-CM code: 053) between 1997 and 2013. Each identified individual with a case of herpes zoster was compared with 1 sex-, age-, and residence-matched control subject. Both groups were followed until the first diagnosis of dementia (ICD-9-CM codes: 290.0 to 290.4, 294.1, 331.0 to 331.2, and 331.82), withdrawal from the registry, or the end of 2013. Cox regression analyses and competing risk model were applied, adjusting for sex, age, residence, depression, autoimmune disease, ischemic stroke, traumatic brain injury, alcohol use disorder, and antiviral treatments for herpes zoster to evaluate the risk of interest. A total of 39,205 cases with herpes zoster were identified. Of the 78,410 study and comparison subjects, 4,204 were diagnosed as having dementia during a mean (SD) follow-up period of 6.22 (4.05) years. Herpes zoster was associated with a slightly increased risk of dementia in the fully adjusted model (hazard ratio [HR] = 1.11; 95% CI, 1.04-1.17). Prescriptions of antiviral therapy were associated with a reduced risk of developing dementia following the diagnosis of herpes zoster (HR = 0.55; 95% CI, 0.40-0.77). Herpes zoster was associated with an increased risk of dementia, independent of potential confounding factors. Antiviral treatment might be protective in preventing dementia in patients with herpes zoster. © Copyright 2017 Physicians Postgraduate Press, Inc.

    This paper provides an update on the incidence of neonatal herpes, guideline adherence by health care professionals (HCP), and trends in genital herpes simplex virus (HSV) infection during pregnancy in the Netherlands. Questionnaires were sent to all hospitals inquiring about numbers and characteristics of neonatal and maternal HSV infections, and guideline adherence between 2012 and 2015. Longitudinal trends were investigated from 1999 onwards using survey data and Perinatal Registry of the Netherlands data (Perined). Trends were smoothed with Poisson regression splines. Risk indicators for neonatal and maternal HSV infections were examined with Poisson regression analyses. Neonatal herpes incidence was 4.8/100,000 live births based on survey data (2012-2015) and 3.4/100,000 based on Perined (2012-2014). Mortality rate was 23% (7/30). Neonatal herpes incidence increased slightly over time as did the prevalence of genital HSV infection among pregnant women. Non-Western ethnicity (RR 1.9, 95%CI 1.5-2.5) and age herpes during pregnancy. In Perined, none of the neonatal herpes cases had a mother diagnosed with an active genital herpes infection during pregnancy. Preventive measures to reduce vertical herpes transmission (such as caesarean section) were less commonly reported by HCP in 2012-2015 compared to 2006-2011. Neonatal herpes incidence in the Netherlands slowly increased over the last 15 years. An increased genital HSV prevalence during pregnancy or, to lower extent, the decreased guideline adherence by HCP may be responsible. A rise in asymptomatic maternal HSV shedding is also plausible, emphasizing the challenges in preventing neonatal herpes.

Um dos extratos (EP1 foi obtido por extração etanólica de própolis obtida da região central do Estado do Rio Grande do Sul e o segundo (EP2, obtido comercialmente de uma empresa de Minas Gerais. A análise dos extratos de própolis através da cromatografia líquida de alta eficiência (CLAE identificou a presença de flavonóides como: rutina, quercetina e ácido gálico. A atividade antiviral bem como a citotoxicidade dos extratos aos cultivos celulares foram avaliadas através do MTT [3- (4,5 dimetiltiazol-2yl-2-5-difenil-2H tetrazolato de bromo]. Ambos os extratos evidenciaram atividade antiviral frente ao BVDV e CAV-2 quando acrescidos ao cultivo celular anteriormente à inoculação viral. Os extratos foram menos efetivos contra o FCV em comparação aos resultados obtidos com os outros vírus, e a atividade antiviral neste caso foi observada apenas quando a própolis estava presente após a inoculação viral.

    Symptom of herpes zoster is sometimes difficult to distinguish from sciatica induced by spinal diseases, including lumbar disc herniation and spinal canal stenosis. Here we report a case of sciatica mimicking lumbar canal stenosis. A 74-year-old Chinese male patient visited our hospital for left-sided sciatic pain upon standing or walking for 5 min of approximately 1 month's duration. At the first visit to our hospital, there were no skin lesions. A magnetic resonance imaging showed spinal canal stenosis between the 4th and 5th lumbar spine. Thus, we diagnosed the patient with sciatica induced by spinal canal stenosis. We considered decompression surgery for the stenosis of 4th and 5th lumbar spine because conservative therapy failed to relieve the patient's symptom. At that time, the patient complained of a skin rash involving his left foot for several days. A vesicular rash and erythema were observed on the dorsal and plantar surfaces of the great toe and lateral malleolus. The patient was diagnosed with herpes zoster in the left 5th lumbar spinal nerve area based on clinical findings, including the characteristics of the pain and vesicular rash and erythema in the 5th lumbar spinal dermatome. The patient was treated with famciclovir (1,500 mg/day) and non-steroidal anti-inflammatory drugs. After 1 week of medication, the skin rash resolved and pain relief was obtained. In conclusion, spinal surgeons should keep in mind herpes zoster infection as one of the possible differential diagnoses of sciatica, even if there is no typical skin rash.

    Etiology, transmission and protection: Herpes simplex virus-2 (HSV-2) is a leading cause of sexually transmitted infections with recurring manifestations throughout the lifetime of infected hosts. Currently no effective vaccines or prophylactics exist that provide complete protection or immunity from the virus, which is endemic throughout the world. Pathology/Symptomatology: Primary and recurrent infections result in lesions and inflammation around the genital area and the latter accounts for majority of genital herpes instances. Immunocompromised patients including neonates are susceptible to additional systemic infections including debilitating consequences of nervous system inflammation. Epidemiology, incidence and prevalence: More than 500 million people are infected worldwide and most reported cases involve the age groups between 16-40 years, which coincides with an increase in sexual activity among this age group. While these numbers are an estimate, the actual numbers may be underestimated as many people are asymptomatic or do not report the symptoms. Treatment and curability: Currently prescribed medications, mostly nucleoside analogs, only reduce the symptoms caused by an active infection, but do not eliminate the virus or reduce latency. Therefore, no cure exists against genital herpes and infected patients suffer from periodic recurrences of disease symptoms for their entire lives. Molecular mechanisms of infection: The last few decades have generated many new advances in our understanding of the mechanisms that drive HSV infection. The viral entry receptors such as nectin-1 and HVEM have been identified, cytoskeletal signaling and membrane structures such as filopodia have been directly implicated in viral entry, host motor proteins and their viral ligands have been shown to facilitate capsid transport and many host and HSV proteins have been identified that help with viral replication and pathogenesis.

    CT findings of six patients with serologically confirmed herpes simplex encephalitis were analyzed sequentially. The initial change in CT scan in 3 cases was generalized cerebral edema instead of low density areas in the anterior temporal lobes, which have generally been known as the initial findings. Then, bilateral (5 cases) or unilateral (1 case) island-shaped low absorption areas in the insular cortex and the claustrum appeared within 10 days of onset in all 6 cases. These findings, especially the latter, seem to be characteristic of the acute stage and useful in the early diagnosis of herpes simplex encephalitis. The low density areas, then, spread to the temporal lobes, rectal and cingulate gyri in the subacute stage (3 cases) and finally to the frontal and occipital lobes in the chronic stage (2 cases). In the basal ganglia, thalamus, brain stem and cerebellum, however, there were no low density areas. In 2 cases there was no progression of low density areas beyond those of the acute stage. In one case there were high density areas in the temporal lobes and parapontine cisterns bilaterally. This could correspond to the pathological findings in herpes simplex encephalitis. The improvement of CT findings (or arrest at the early stage) was noted in 2 cases in which the clinical state also improved. This might well be the effect of adenine arabinoside. The one case treated with cytosine arabinoside had extensive low density areas in CT and finally died. The importance of CT in the evaluation of adenine arabinoside therapy was stressed. (author)

    SUMMARY Impairment of varicella zoster virus (VZV)-specific cell-mediated immunity, including impairment due to immunosenescence, is associated with an increased risk of developing herpes zoster (HZ), whereas levels of anti-VZV antibodies do not correlate with HZ risk. This crucial role of VZV-specific cell-mediated immunity suggests that boosting these responses by vaccination will be an effective strategy for reducing the burden of HZ. Other strategies focus on preventing the major complication of HZ – post-herpetic neuralgia. These strategies include pre-emptive treatment with drugs such as tricyclic antidepressants, anticonvulsants and analgesics. PMID:20510262

    Full Text Available Fifty men with recurrent genital herpes were treated with either acyclovir 5% cream or tromantidine 1 % ointment applied topically. Acyclovir cream was applied 5 times and tromantidine cream 4 times daily for 5 days. At least one pre-treatment episode was observed by one of the authors. Self assessment charts were provided to the patients to record prodromal symptoms and healing time. For comparison at least 3 post treatment episodes were observed and com-pared with mean healing time of 3 pre-treatment episodes. Both acyclovir cream and tromantidine ointment significantly reduced the duration of prodrome, hastened healing and so reduced mean healing time.

    Enhanced reactivation of Ultraviolet-irradiated virus has been reported to occur in heat-shocked host cells. Since enhanced virus reactivation is often accompanied by untargeted mutagenesis, we investigated whether such mutagenesis would occur for herpes simplex virus (HSV) in CV-1 monkey kidney cells subjected to heat shock. In addition to expressing enhanced reactivation, the treated cells were transiently more susceptible to infection by unirradiated HSV. No mutagenesis of unirradiated HSV was found whether infection occurred at the time of increased susceptibility to infection or during expression of enhanced viral reactivation

    Herpes simplex encephalitis (HSE) is the most common sporadically appearing encephalitis in Central Europe. Differential diagnosis to brain tumors or spontaneous intercerebral hemorrhage is difficult. There are CT scan findings which are characteristic of HSE but there are no pathognomonic patterns. These characteristic findings are helpful in differential diagnosis to neoplastic or vascular processes. Thus, other diagnostic procedures (i.e. brain biopsy) to confirm diagnosis of HSE and effective therapy may be carried out in time. The difficulties in differential diagnosis are shown by the presented case. (orig.) [de

    Herpes zoster (HZ) infection has been reported as a rare cause of acute urinary retention. HZ infection involving sacral, thoracolumbar, and rarely high thoracic dermatomes is believed to occasionally cause motor and sensory neuropathy of the bladder. This is specifically achieved by the interruption of the detrusor reflex causing subsequent bladder atonia. As the course and management of this entity is quite benign, HZ should remain a diagnostic consideration in the management of urinary retention. We report a case of acute urinary retention of approximately 2.5 liters associated with HZ infection and review the proposed pathogenesis and therapeutic considerations in the management of this entity.

    Acute urinary retention in women is rare. The varicella-zoster virus causes inflammatory lesions of the sensory-root ganglions, meninges and, less frequently, spinal cord. Herpes zoster has been reported to affect, although rarely, lower urinary tract innervations, and acute urinary retention can be thought to occur in the presence of sacral dermatome involvement. Usually it is located in S2-4 dermatome and the prognosis for acute urinary retention is benign resolving in about 20 days. We present a case in which the S1 dermatome was involved and acute urinary retention developed. After 10 days of specific therapy and self-catheterization the problem resolved.

    The implications for sexual abuse investigation of genital herpes in a child are uncertain because of a lack of good quality research evidence. The incidence, presenting features, history of exposure, indicators of child maltreatment and outcomes of child protection investigations in children with genital herpes are described. Ascertainment of all cases of genital herpes in children herpes simplex type 1, eight were tested for other sexually transmitted infections (STIs), and only one had a full STI screen. Three cases had other clinical features suggestive of sexual abuse. Six cases were referred for child protection investigation, but no sexual abuse was substantiated. Genital herpes in children under 11 years is rare. Almost a third of children diagnosed with genital herpes did not have appropriate virological investigation and few were screened for other STIs. Around a quarter of cases were referred to child protection agencies for further investigation, which limits any inferences in this study about mode of transmission in children. Sexual abuse guidance should emphasise the need for thorough assessment and investigation in cases of genital herpes in children.

    To estimate the frequency of isolation of herpes simplex virus (HSV) from the genital tract when recurrent herpes lesions were present on the buttocks. Data were extracted from a prospectively observed cohort attending a research clinic for genital herpes infections between 1975 and 2001. All patients with a documented herpes lesion on the buttocks, upper thigh or gluteal cleft ("buttock recurrence") and concomitant viral cultures from genital sites including the perianal region were eligible. We reviewed records of 237 subjects, 151 women and 86 men, with a total of 572 buttock recurrences. Of the 1,592 days with genital culture information during a buttock recurrence, participants had concurrent genital lesions on 311 (20%, 95% confidence interval [CI] 14-27%) of these days. Overall, HSV was isolated from the genital region on 12% (95% CI 8-17%) of days during a buttock recurrence. In the absence of genital lesions, HSV was isolated from the genital area on 7% (95% CI 4%-11%) of days during a buttock recurrence and, among women, from the vulvar or cervical sites on 1% of days. Viral shedding of herpes simplex virus from the genital area is a relatively common occurrence during a buttock recurrence of genital herpes, even without concurrent genital lesions, reflecting perhaps reactivation from concomitant regions of the sacral neural ganglia. Patients with buttock herpes recurrences should be instructed about the risk of genital shedding during such recurrences. II-2.

    Herpes zoster is an important problem of public health especially among the elderly in Spain. A population-based retrospective epidemiological study to estimate the burden of herpes zoster requiring hospitalization in the Canary Islands, Spain was conducted by using data from the national surveillance system for hospital data, Conjunto Mínimo Básico de Datos. Records of all patients admitted to hospital with a diagnosis of herpes zoster in any position and cases of primary diagnosis (ICD-9-MC codes 053.0-053.9) during a 10-year period (2005-2014), were selected. A total of 1088 hospitalizations with a primary or secondary diagnosis of herpes zoster were identified during the study period. Annually there were 6.99 hospitalizations by herpes zoster per 100,000 population. It increases with age reaching a maximum in persons ≥85 years of age (43.98 admissions per 100,000). Average length of hospitalization was 16 days and 73 patients died, with a case-fatality rate of 4.03%. In 22% of the cases hospitalized, herpes zoster was the primary diagnosis. The hospitalization burden of herpes zoster in adults in the Canary Islands was still important during the last decade and justify the implementation of preventive measures, like vaccination in the elderly or other high risk groups to reduce the most severe cases of the disease.

    Abstract Background: Herpesvirus infections often complicate the clinical course of patients with inflammatory bowel disease; however, invasive disease due to herpes simplex virus is distinctly uncommon. Methods: We present a case of herpes simplex virus colitis and hepatitis, review all the previously published cases of herpes simplex virus colitis, and discuss common clinical features and outcomes. We also discuss the epidemiology, clinical manifestations, diagnosis, and management of herpes simplex virus infections, focusing specifically on patients with inflammatory bowel disease. Results: A 43-year-old man with ulcerative colitis, previously controlled with an oral 5-aminosalicylic agent, developed symptoms of a colitis flare that did not respond to treatment with systemic corticosteroid therapy. One week later he developed orolabial ulcers and progressive hepatic dysfunction, with markedly elevated transaminases and coagulopathy. He underwent emergent total colectomy when imaging suggested bowel micro-perforation. Pathology from both the colon and liver was consistent with herpes simplex virus infection, and a viral culture of his orolabial lesions and a serum polymerase chain reaction assay also identified herpes simplex virus. He was treated with systemic antiviral therapy and made a complete recovery. Conclusions: Disseminated herpes simplex virus infection with concomitant involvement of the colon and liver has been reported only 3 times in the published literature, and to our knowledge this is the first such case in a patient with inflammatory bowel disease. The risk of invasive herpes simplex virus infections increases with some, but not all immunomodulatory therapies. Optimal management of herpes simplex virus in patients with inflammatory bowel disease includes targeted prophylactic therapy for patients with evidence of latent infection, and timely initiation of antiviral therapy for those patients suspected to have invasive disease.

  3. The molecular basis of herpes simplex virus latency

    Herpes simplex virus type 1 is a neurotropic herpesvirus that establishes latency within sensory neurones. Following primary infection, the virus replicates productively within mucosal epithelial cells and enters sensory neurones via nerve termini. The virus is then transported to neuronal cell bodies where latency can be established. Periodically, the virus can reactivate to resume its normal lytic cycle gene expression programme and result in the generation of new virus progeny that are transported axonally back to the periphery. The ability to establish lifelong latency within the host and to periodically reactivate to facilitate dissemination is central to the survival strategy of this virus. Although incompletely understood, this review will focus on the mechanisms involved in the regulation of latency that centre on the functions of the virus-encoded latency-associated transcripts (LATs), epigenetic regulation of the latent virus genome and the molecular events that precipitate reactivation. This review considers current knowledge and hypotheses relating to the mechanisms involved in the establishment, maintenance and reactivation herpes simplex virus latency. PMID:22150699

  4. Delays in initiation of acyclovir therapy in herpes simplex encephalitis.

    Diagnosis of herpes simplex encephalitis (HSE) is based on clinical findings, MRI, and detection of herpes simplex virus (HSV) DNA in cerebrospinal fluid (CSF) using polymerase chain reaction amplification. Delays in starting treatment are associated with poorer clinical outcomes. We assessed the timing of initiation of acyclovir therapy in HSE. Inpatient databases from seven hospitals in Winnipeg, Manitoba were used to identify individuals diagnosed with encephalitis and HSE from 2004 to 2009. The time taken to initiate therapy with acyclovir and the reasons for delays were determined. Seventy-seven patients were identified; 69 (90%) received acyclovir; in the others a non-HSV infection was strongly suspected. Thirteen patients were subsequently confirmed to have HSE. Acyclovir was initiated a median of 21 hours (3-407) after presentation in encephalitis cases, and a median of 11 hours (3-118) in HSE. The most common reason for delay was a failure to consider HSE in the differential diagnosis, despite suggestive clinical features. Where therapy was delayed in HSE patients, the decision to begin acyclovir was prompted by transfer of the patient to a different service (55%), recommendations by consultants (18%), imaging results (18%), and CSF pleocytosis (9%). Delays in initiating acyclovir for HSE are common, and are most often due to a failure to consider HSE in a timely fashion on presentation. In order to improve patient outcomes, physicians should be more vigilant for HSE, and begin acyclovir therapy expeditiously on the basis of clinical suspicion rather than waiting for confirmatory tests.

  5. Unusual Initial Presentation of Herpes Simplex Virus as Inguinal Lymphadenopathy

    Full Text Available Genital herpes simplex virus (HSV infections are a common cause of inguinal lymphadenopathy. However, surgical excision of enlarged inguinal nodes is almost never performed to initially diagnose genital herpes simplex virus, due to the distinct external presentation of genital herpetic vesicles that usually occur with the first symptoms of infection. Therefore, the histologic and immunophenotypic features of HSV-associated inguinal lymphadenopathy are unfamiliar to most pathologists. The current report describes the lymph node pathology of two immunocompetent patients, whose initial HSV diagnosis was established through surgical excision of enlarged inguinal lymph nodes. Histologic examination showed features consistent with viral lymphadenopathy, including florid follicular hyperplasia, monocytoid B-cell hyperplasia, and paracortical hyperplasia without extensive necrosis. Immunohistochemical stains for HSV antigens, using polyclonal anti-HSV I and II antibodies, demonstrate strong immunoreactivity for HSV in a small number of cells in the subcapsular sinuses, especially in areas with monocytoid B-cell hyperplasia. Rare scattered HSV-positive cells also are identified in paracortical areas and germinal centers. We conclude that an initial diagnosis of genital HSV infection may be established by inguinal lymph node biopsy.

  6. Exploiting Herpes Simplex Virus Entry for Novel Therapeutics

    2013-06-01

    Full Text Available Herpes Simplex virus (HSV is associated with a variety of diseases such as genital herpes and numerous ocular diseases. At the global level, high prevalence of individuals who are seropositive for HSV, combined with its inconspicuous infection, remains a cause for major concern. At the molecular level, HSV entry into a host cell involves multiple steps, primarily the interaction of viral glycoproteins with various cell surface receptors, many of which have alternate substitutes. The molecular complexity of the virus to enter a cell is also enhanced by the existence of different modes of viral entry. The availability of many entry receptors, along with a variety of entry mechanisms, has resulted in a virus that is capable of infecting virtually all cell types. While HSV uses a wide repertoire of viral and host factors in establishing infection, current therapeutics aimed against the virus are not as diversified. In this particular review, we will focus on the initial entry of the virus into the cell, while highlighting potential novel therapeutics that can control this process. Virus entry is a decisive step and effective therapeutics can translate to less virus replication, reduced cell death, and detrimental symptoms.

  7. Rapid Detection of Herpes Viruses for Clinical Applications

    There are eight herpes viruses that infect humans, causing a wide range of diseases resulting in considerable morbidity and associated costs. Varicella zoster virus (VZV) is a human herpes virus that causes chickenpox in children and shingles in adults. Approximately 1,000,000 new cases of shingles occur each year; post-herpetic neuralgia (PHN) follows shingles in 100,000 to 200,000 people annually. PHN is characterized by debilitating, nearly unbearable pain for weeks, months, and even years. The onset of shingles is characterized by pain, followed by the zoster rash, leading to blisters and severe pain. The problem is that in the early stages, shingles can be difficult to diagnose; chickenpox in adults can be equally difficult to diagnose. As a result, both diseases can be misdiagnosed (false positive/negative). A molecular assay has been adapted for use in diagnosing VZV diseases. The polymerase chain reaction (PCR) assay is a non-invasive, rapid, sensitive, and highly specific method for VZV DNA detection. It provides unequivocal results and can effectively end misdiagnoses. This is an approximately two-hour assay that allows unequivocal diagnosis and rapid antiviral drug intervention. It has been demonstrated that rapid intervention can prevent full development of the disease, resulting in reduced likelihood of PHN. The technology was extended to shingles patients and demonstrated that VZV is shed in saliva and blood of all shingles patients. The amount of VZV in saliva parallels the medical outcome.

    The aim of this study was to describe the findings on plain chest radiographs in patients with herpes simplex virus pneumonia (HSVP). The study was based on 17 patients who at a retrospective search have been found to have a monoinfection with herpes simplex virus. The diagnosis was established by isolation of the virus from material obtained during fiberoptic bronchoscopy (FOB) which also included broncho-alveolar lavage and tissue sampling. Fourteen patients had a chest radiograph performed within 24 h of the date of the FOB. Two radiographs showed no abnormalities of the lung parenchyma. The radiographs of the other 12 patients showed lung opacification, predominantly lobar or more extensive and always bilateral. Most patients presented with a mixed airspace and interstitial pattern of opacities, but 11 of 14 showed at least an airspace consolidation. Lobar, segmental, or subsegmental atelectasis was present in 7 patients, and unilateral or bilateral pleural effusion in 8 patients, but only in 1 patient was it a large amount. In contradiction to the literature which reports a high correlation between HSVP and acute respiratory distress syndrome (ARDS), 11 of 14 patients did not meet the pathophysiological criteria for ARDS. The radiologist may suggest the diagnosis of HSVP when bilateral airspace consolidation or mixed opacities appear in a susceptible group of patients who are not thought to have ARDS or pulmonary edema. The definite diagnosis of HSV pneumonia can be established only on the basis of culture of material obtained by broncho-alveolar lavage. (orig.)

    A nucleic acid vaccine, expressing the gene encoding herpes simplex virus (HSV) type 2 glycoprotein D (gD2) under control of the cytomegalovirus immediate-early gene promoter, was used to immunize guinea pigs against genital HSV-2 infection. The vaccine elicited humoral immune responses comparable to those seen after HSV-2 infection. Immunized animals exhibited protection from primary genital HSV-2 disease with little or no development of vesicular skin lesions and significantly reduced HSV-2 replication in the genital tract. After recovery from primary infection, immunized guinea pigs experienced significantly fewer recurrences and had significantly less HSV-2 genomic DNA detected in the sacral dorsal root ganglia compared with control animals. Thus, immunization reduced the burden of latent infection resulting from intravaginal HSV-2 challenge, and a nucleic acid vaccine expressing the HSV-2 gD2 antigen protected guinea pigs against genital herpes, limiting primary infection and reducing the magnitude of latent infection and the frequency of recurrent disease.

    The major features that distinguish recurrent herpes simplex virus infections from zoster are illustrated in this article by two case histories. The clinical and epidemiologic features that characterize recurrent herpes simplex virus and varicella-zoster virus infections are reviewed. It is noted that herpesvirus infections are more common and severe in patients with cellular immune deficiency. Each virus evokes both humoral and cellular immune response in the course of primary infection. DNA hybridization studies with RNA probes labelled with sulfur-35 indicate that herpes simplex viruses persist within neurons, and that varicella-zoster virus is found in the satellite cells that encircle the neurons

    The psychopathological symptoms occurring in the course of diseases associated with infections are often initially isolated and non-characteristic, and may cause diagnostic difficulties. Moreover, such disorders tend to be less responsive to psychiatric management. Among possible causes such as trauma, neoplasm and vascular changes, inflammatory changes of the brain as a result of a viral infection should also be considered. There were 452 registered cases of viral encephalitis in Poland in 2010, and although not very prevalent they remain a severe and life-threatening condition. What is more, the frequently occurring neurological and psychiatric complications of viral encephalitis often result in permanent disabilities, causing a significant decrease in the quality of life. This article presents the three types of encephalitis that are most prevalent among immunocompetent patients in Poland, i.e. herpes simplex encephalitis (HSE), tick-borne encephalitis (TBE) and herpes zoster encephalitis (HZE). The psychopathology of the acute phase of the infection, the residual symptoms, features apparent in imaging studies and some neuropathological aspects are also presented. The paper also focuses on psychiatric aspects of the diagnostics and treatment of the described conditions. The clinical pictures of these infections are quite specific, although they cover a wide range of symptoms, and these characteristic features are described. The aim of this review is also to show the significance of thorough diagnostics and a multidisciplinary approach to patients with viral CNS infections.

    Herpes simplex encephalitis (HSE) is associated with significant mortality and morbidity. As a consequence of HSE, up to 75% of infected individuals die or experience irreversible neurological damage. While the pathogenesis of the disease is unknown, it is traditionally hypothesized that the viral infection occurs by neuronal transmission directly from peripheral sites. Non-neuronal modes of infection have generally been overlooked as the brain is protected by the blood-brain-barrier (BBB). The BBB poses an effective barrier to pathogens as well as to drugs such as chemotherapies. In the pursuit to deliver chemotherapeutic agents to the brain, several studies demonstrated that phosphodiesterase type 5 (PDE5) inhibitors, such as sildenafil, may increase the permeability of the BBB enabling successful delivery of chemotherapeutic agents to the brain. In this communication, we report a case of HSE infection in a 62-year-old man, which we suspect was facilitated by the use of sildenafil during a primary genital herpes simple virus (HSV) infection. Due to large number of patients treated with PDE5 inhibitors for erectile dysfunction and the high incidence of genital HSV infection in the general population, a larger study should examine the potential risk of developing HSE in patients treated with PDE5 inhibitors.

    Varicella results from a primary infection with the varicella virus while herpes zoster is caused by a reactivation of a latent infection. Dissemination of herpes zoster is uncommon in immunocompetent individuals. Reports of disseminated herpes zoster in children are even less common than in adults. An unusual case of disseminated herpes zoster ophthalmicus in an 8-year old immunocompetent black boy is presented. He had a previous primary Varicella zoster virus infection at three years of age. In the current report, he presented during an on-going chicken pox outbreak and survived with no significant complications. A breakthrough varicella virus re-infection or a reactivation is possible, both of which could present as zoster. This case emphasizes the need for prevention of varicella virus infection through universal childhood immunization and effective infection control strategies in health care settings.

    Herpes simplex virus-specific DNA sequences have been detected by Southern hybridization analysis in both central and peripheral nervous system tissues of latently infected mice. We have detected virus-specific sequences corresponding to the junction fragment but not the genomic termini, an observation first made by Rock and Fraser (Nature [London] 302:523-525, 1983). This "endless" herpes simplex virus DNA is both qualitatively and quantitatively stable in mouse neural tissue analyzed over a 4-month period. In addition, examination of DNA extracted from human trigeminal ganglia has shown herpes simplex virus DNA to be present in an "endless" form similar to that found in the mouse model system. Further restriction enzyme analysis of latently infected mouse brainstem and human trigeminal DNA has shown that this "endless" herpes simplex virus DNA is present in all four isomeric configurations.

    An effective vaccine for genital herpes has been difficult to achieve because of the limited efficacy of subunit vaccines and the safety concerns about live viruses. As an alternative approach, mutant herpes simplex virus strains that are replication-defective can induce protective immunity. To increase the level of safety and to prove that replication was not needed for immunization, we constructed a mutant herpes simplex virus 2 strain containing two deletion mutations, each of which eliminated viral replication. The double-mutant virus induces protective immunity that can reduce acute viral shedding and latent infection in a mouse genital model, but importantly, the double-mutant virus shows a phenotypic defect in latent infection. This herpes vaccine strain, which is immunogenic but has defects in both productive and latent infection, provides a paradigm for the design of vaccines and vaccine vectors for other sexually transmitted diseases, such as AIDS.

    Infection with herpes simplex virus often results in a latent infection of local sensory ganglia and a disease characterized by periodic viral reactivation and mucocutaneous lesions. The factors that trigger reactivation in humans are still poorly defined. In our study, five patients with documented histories of recurrent herpes simplex virus infection on the buttocks or sacrum were exposed to three times their minimal erythema dose of ultraviolet light. Site-specific cutaneous herpes simplex virus infection occurred at 4.4 +/- 0.4 days after exposure to ultraviolet light in 8 of 13 attempts at reactivation. We conclude that ultraviolet light can reactivate herpes simplex virus under experimentally defined conditions. This model in humans should prove useful in evaluating the pathophysiology and prevention of viral reactivation

    During a 3-month period, 131 cases of herpes zoster were diagnosed in Kigali, Rwanda. There were 46 female and 85 male patients. Mean age was 29 years (range 1-66). An unusually high proportion of patients presented with cranial and sacral nerve localisation of their cutaneous lesions. 55/131 patients (42%) had involvement of more than one dermatome. None of the patients had an underlying condition known to favour herpes zoster. 120/131 (92%) had antibodies to HIV detected by an immunoenzymatic assay (EIA) and indirect immunofluorescence. 92/125 adult patients (74%) had no sign or symptom related to HIV infection other than herpes zoster. This study suggests that herpes zoster in Central Africa is an early and readily detectable manifestation of HIV-induced immunosuppression.

    Full Text Available Blazed up Herpes zoster lesions have been described in very few patients after free and pedicled flap transfer for reconstructive purpose. Although sensory recovery after flap reconstructions has been studied extensively most studies addressed subjective perceptions of sensation. Objective investigations of spontaneous reinervation of free and pedicled flaps are rare. We would like to present a witnessed herpes zoster infection of a latissimus dorsi skin flap 2 years after breast reconstruction.

    Retrospective analysis of 210 cases of patients with Hodgkin's disease revealed an overall incidence of herpes zoster varicella of 9.5 per cent. Patients with the mixed cellular histological subtype showed a significantly increased (p < 0.05) risk as compared with the total population. More than 90 per cent of the herpes zoster varicella infections occurred after termination of treatment; a combination of radiotherapy with chemotherapy proved to be a predisposing factor. (Auth.)

    Full Text Available The metal-ceramic composite actuators, moonies and cymbals consist in capped piezoceramic disks with metallic endcaps having cavities inside. These cavities favour the amplification of direct and reverse piezoelectric effects. These actuators fill the gap between high displacement low generative force bimorph actuators and low displacement high generative force multilayer ceramic actuators. The moonie actuator can give displacements greater than 100 mm, maximum generative force of 3N to several N´s, response time of 20 to 100 ms, and low fatigue test response for more than 107 cycles. Cymbals actuators shows twice as big as displacement than moonie for the studied size, much higher generative force and the possibility to avoid the temperature dependence of the displacement for selected materials. Properties of cymbal actuators can be tailored trough the selection of materials. Also, cymbal actuators can be tuned to adopt different resonance frequencies.

    2013-06-01

    Full Text Available The aim of the study: Modification in the treatment of patients with herpes associated with psoriasis. Materials and methods: 30 patients were included in the study divided into two groups. In the 1st group the patients received standard treatment for herpes and two daily applications of cikloferon liniment for seven days. In the 2nd group the patients received only standard treatment for herpes. The patients were followed-up for six months. The study was open-label randomized. Results: The results obtained show that general infectious symptoms of herpes subsided considerably faster in the 1st group of patients treated with cikloferon liniment. The applications with the topical immunomodulator enhanced more dynamic disappearance of erosions. During the six months follow-up exacerbations of herpes were noted in 10% of patients in the 1st group and in 30% of patients in the second group. Cikloferon liniment was well tolerated and no side effects were noted. Conclusion: Cikloferon liniment used for the treatment of patients with herpes exacerbation associated with psoriasis contributes to more dynamic disappearance of infectious syndrome, enhances epithelization of herpetic erosions, and lowers the duration of erosions and local inflammation as well as the number of exacerbations in catamnesis.

    We present a case of reactivated herpes zoster keratouveitis of 6 years duration with corneal perforation requiring penetrating keratoplasty shortly after inoculation with herpes zoster vaccine (Zostavax, Merck, Quebec, Canada). Retrospective case report. A 67-year-old woman with a 5-year history of recurrent unilateral herpes zoster keratouveitis in her right eye presented with another recurrence 2 weeks after Zostavax vaccination. Three months later, she developed descemetocele and 2 months afterward, corneal perforation, which was managed by penetrating keratoplasty. Immunohistopathological examination disclosed positive staining for varicella zoster virus in most of the keratocytes adjacent to the descemetocele and perforation, most vividly in the deeper two-thirds of the stroma where the keratocytes were most dense, but not in corneal epithelium or endothelium. Electron microscopic examination showed universally severely degenerated corneal keratocytes in the corneal stroma adjacent to the perforation with variable numbers of herpes virus capsids present in half of these cells. Only a rare normal-appearing keratocyte was identified in the more peripheral corneal stroma. We present a case of reactivation of herpes keratouveitis shortly after vaccination with Zostavax in a patient with previous herpes zoster ophthalmicus. We demonstrate, for the first time, ultrastructural evidence consistent with inactive virus capsids in diffusely degenerated keratocytes in the extracted corneal tissue.

    A new human herpes virus has been isolated from CD4 + T cells purified from peripheral blood mononuclear cells of a healthy individual (RK), following incubation of the cells under conditions promoting T-cell activation. The virus could not be recovered from nonactivated cells. Cultures of lymphocytes infected with the RK virus exhibited a cytopathic effect, and electron microscopic analyses revealed a characteristic herpes virus structure. RK virus DNA did not hybridize with large probes derived from herpes simplex virus, Epstein-Barr virus, varicella-zoster virus, and human cytomegalovirus. The genetic relatedness of the RK virus to the recently identified T-lymphotropic human herpes virus 6 (HHV-6) was investigated by restriction enzyme analyses using 21 different enzymes and by blot hydridization analyses using 11 probes derived from two strains of HHV-6 (Z29 and U1102). Whereas the two HHV-6 strains exhibited only limited restriction enzyme polymorphism, cleavage of the RK virus DNA yielded distinct patterns. Of the 11 HHV-6 DNA probes tested, only 6 cross-hybridized with DNA fragments derived from the RK virus. Taken together, the maximal homology amounted to 31 kilobases of the 75 kilobases tested. The authors conclude that the RK virus is distinct from previously characterized human herpesviruses. The authors propose to designate it as the prototype of a new herpes virus, the seventh human herpes virus identified to date

    Current treatment of genital herpes is focused on ameliorating signs and symptoms but is not curative. However, as potential herpes simplex virus (HSV) cure approaches are tested in the laboratory, we aimed to assess the interest in such studies by persons with genital herpes and the willingness to assume risks associated with experimental therapy. We constructed an anonymous online questionnaire that was posted on websites that provide information regarding genital herpes. The questions collected demographic and clinical information on adults who self-reported as having genital herpes, and assessed attitudes toward and willingness to participate in HSV cure clinical research. Seven hundred eleven participants provided sufficient responses to be included in the analysis. Sixty-six percent were women; the median age was 37 years, and the median time since genital HSV diagnosis was 4.7 years. The willingness to participate in trials increased from 59.0% in phase 1 to 68.5% in phase 2, and 81.2% in phase 3 trials, and 40% reported willingness to participate even in the absence of immediate, personal benefits. The most desirable outcome was the elimination of risk for transmission to sex partner or neonate. The mean perceived severity of receiving a diagnosis of genital HSV-2 was 4.2 on a scale of 1 to 5. Despite suppressive therapy available, persons with genital herpes are interested in participating in clinical research aimed at curing HSV, especially in more advanced stages of development.

    The aims of this study were to examine pre-existing videos in order to explore the motivation for, possible approaches to, and timing and context of disclosure of genital herpes infection as described by the lay public. A thematic content analysis was performed on 63 videos submitted to an Australian online contest sponsored by the Australian Herpes Management Forum and Novartis Pharmaceuticals designed to promote disclosure of genital herpes. Videos either provided a motivation for disclosure of genital herpes or directed disclosure without an explicit rationale. Motivations included manageability of the disease or consistency with important values. Evaluation of strategies and logistics of disclosure revealed a variety of communication styles including direct and indirect. Disclosure settings included those that were private, semiprivate and public. Disclosure was portrayed in a variety of relationship types, and at different times within those relationships, with many videos demonstrating disclosure in connection with a romantic setting. Individuals with genital herpes are expected to disclose to susceptible partners. This analysis suggests that understanding lay perspectives on herpes disclosure to a partner may help healthcare providers develop counselling messages that decrease anxiety and foster disclosure to prevent transmission.

    Glycoprotein B (gB), C (gC) and D (gD) of herpes simplex virus are implicated in virus adsorption and penetration. The gB, gC and gD are glycoproteins for different processes of virus binding and attachment to the host cells. Moreover, their expression is necessary and sufficient to induce cell fusion in the absence of other glycoproteins. Egress of herpes simplex virus (HSV) and other herpes viruses from cells involves extensive modification of cellular membranes and sequential envelopment, de-envelopment and re-envelopment steps. Viral glycoproteins are important in these processes, and frequently two or more glycoproteins can largely suffice in any step. Hence, we target the 3 important glycoproteins (B, C and D) of eight different herpes viruses of different species. These species include human (HSV1 and 2), bovine (BHV1), equine (EHV1 and 4), chicken (ILT1 and MDV2) and pig (PRV1). By applying different bioinformatics tools, we highlighted the conserved sites in these glycoproteins which might be most significant regarding attachment and infection of the viruses. Moreover the conserved domains in these glycoproteins are also highlighted. From this study, we will able to analyze the role of different viral glycoproteins of different species during herpes virus adsorption and penetration. Moreover, this study will help to construct the antivirals that target the glycoproteins of different herpes viruses. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2015-12-01

    Full Text Available Introduction: Herpes Zoster (HZ is rare in infancy and results from reactivation of varicella-zoster virus, latent in the dorsal root ganglia of sensory or cranial nerves after primary infection (chickenpox. Case Report: We describe the case of an healthy infant, three months old, without previous clinical symptoms of chickenpox, in spite of having contacted with the disease at two weeks of life. She was hospitalized for vesicular-papular rash involving unilaterally dermatomes L4 and L5 and was treated with acyclovir with good clinical outcome. Conclusion: The immaturity of the immune system and the interference of maternal antibodies contribute to the manifestation of HZ in the first year of life. In a previously healthy child it is not recommended the exclusion of underlying immunodeficiency or malignant disease.

  6. Herpes Zoster Cervical Myelitis in a Young Adult

    2010-11-01

    Full Text Available Varicella zoster virus infection, which causes chickenpox and herpes zoster (HZ, is not uncommon in the general population. Varicella zoster virus can be latent in cranial nerve or dorsal root ganglia, and reactivate several decades later to produce vesicles with post-herpetic neuralgia. HZ myelitis usually occurs in elderly or immunocompromised patients. We report here a case of HZ myelitis of the cervical spinal cord in a 35-year-old woman who was immunocompetent. Cervical myelitis developed 1 month after the eruption of vesicles. Pure sensation loss was limited initially from the C2 to T1 dermatomes, but later progressed to lower limb sensory loss and sphincter function impairment. The patient's motor function was also mildly affected. Despite the initial rapid neurological deterioration, the symptoms dramatically improved after 5 days of parenteral acyclovir and steroid administration with rehabilitation. We therefore propose that early medical intervention is necessary for better and earlier recovery.

  7. UV radiation and mouse models of herpes simplex virus infection

    Orolabial human infections with herpes simplex virus type 1 (HSV-1) are very common; following the primary epidermal infection, the virus is retained in a latent form in the trigeminal ganglia from where it can reactivate and cause a recrudescent lesion. Recrudescences are triggered by various stimuli including exposure to sunlight. In this review three categories of mouse models are used to examine the effects of UV irradiation on HSV infections: these are UV exposure prior to primary infection, UV exposure as a triggering event for recrudescence and UV exposure prior to challenge with virus is mice already immunized to HSV. In each of these models immunosuppression occurs, which is manifest, in some instances, in increased morbidity or an increased rate of recrudescence. Where known, the immunological mechanisms involved in the models are summarized and their relevance to human infections considered. (Author)

    Surgical site infections (SSIs) are infections of tissues, organs, or spaces exposed by surgeons during performance of an invasive procedure. SSIs are classified into superficial, which are limited to skin and subcutaneous tissues, and deep. The incidence of deep SSIs in lung transplant (LTx) patients is estimated at 5%. No reports have been published as to the incidence of superficial SSIs specifically in LTx patients. Common sense would dictate that the majority of superficial SSIs would be bacterial. Uncommonly, fungal SSIs may occur, and we believe that no reports exist as to the incidence of viral wound infections in LTx patients, or in any solid organ transplant patients. We report a de novo superficial wound infection with herpes simplex virus following lung transplantation, its possible source, treatment, and resolution. © 2017 John Wiley & Sons A/S.

    2011-01-01

    Neonatal herpes simplex virus (HSV) infection continues to cause significant morbidity and mortality despite advances in diagnosis and treatment. Prior to antiviral therapy, 85% of patients with disseminated HSV disease and 50% of patients with central nervous system disease died within 1 year. The advent of antiviral therapy has dramatically improved the prognosis of neonatal HSV with initially vidarabine and subsequently acyclovir increasing the survival rate of infected neonates and improving long-term developmental outcomes. More recently, polymerase chain reaction has allowed earlier identification of HSV infection and provided a quantitative guide to treatment. Current advances in the treatment of neonatal HSV infections are looking toward the role of prolonged oral suppression therapy in reducing the incidence of recurrent disease. Of concern, however, are increasing reports of acyclovir-resistant HSV isolates in patients following prolonged therapy.

    Herpes simplex virus type 1 capsids bud at nuclear membranes and Golgi membranes acquiring an envelope composed of phospholipids. Hence, we measured incorporation of phospholipid precursors into these membranes, and quantified changes in size of cellular compartments by morphometric analysis. Incorporation of [{sup 3}H]-choline into both nuclear and cytoplasmic membranes was significantly enhanced upon infection. [{sup 3}H]-choline was also part of isolated virions even grown in the presence of brefeldin A. Nuclei expanded early in infection. The Golgi complex and vacuoles increased substantially whereas the endoplasmic reticulum enlarged only temporarily. The data suggest that HSV-1 stimulates phospholipid synthesis, and that de novo synthesized phospholipids are inserted into nuclear and cytoplasmic membranes to i) maintain membrane integrity in the course of nuclear and cellular expansion, ii) to supply membrane constituents for envelopment of capsids by budding at nuclear membranes and Golgi membranes, and iii) to provide membranes for formation of transport vacuoles.

    The lack of neurologic symptoms is rare in herpes simplex encephalitis (HSE). A 42-year-old woman presented with psychiatric features alone, such as Korsakoff syndrome and abortive type Kluver-Bucy syndrome. The diagnosis of HSE was confirmed by serologically elevated antibody titer. The patient underwent both X-ray computed tomography and magnetic resonance imaging (MRI). X-ray computed tomography showed transient contrast enhancement and low density area confined to the lateral lobe. Magnetic resonance imaging revealed diffuse areas with a high MRI signal intensity. Considering that the lack of neurologic features, as seen in the present HSE patient, may sometimes rule out the possibility of parenchymal disease, imaging modalities, especially MRI, may be of value in the detection of lesions for HSE.

    2012-06-01

    Herpes simplex virus type 1 (HSV-1) strain KOS has been extensively used in many studies to examine HSV-1 replication, gene expression, and pathogenesis. Notably, strain KOS is known to be less pathogenic than the first sequenced genome of HSV-1, strain 17. To understand the genotypic differences between KOS and other phenotypically distinct strains of HSV-1, we sequenced the viral genome of strain KOS. When comparing strain KOS to strain 17, there are at least 1,024 small nucleotide polymorphisms (SNPs) and 172 insertions/deletions (indels). The polymorphisms observed in the KOS genome will likely provide insights into the genes, their protein products, and the cis elements that regulate the biology of this HSV-1 strain.

    The infections with herpes simplex virus type 1 and type 2 (HSV-1 & HSV-2) have been prevalent since the ancient Greek times. To this day, they still affect a staggering number of over a half billion individuals worldwide. HSV-2 infections cause painful genital herpes, encephalitis, and death in newborns. HSV-1 infections are more prevalent than HSV-2 infections and cause potentially blinding ocular herpes, oro-facial herpes and encephalitis. While genital herpes in mainly caused by HSV-2 infections, in recent years, there is an increase in the proportion of genital herpes caused by HSV-1 infections in young adults, which reach 50% in some western societies. While prophylactic and therapeutic HSV vaccines remain urgently needed for centuries their development has been notoriously difficult. During the most recent National Institute of Health (NIH) workshop titled "Next Generation Herpes Simplex Virus Vaccines: The Challenges and Opportunities", basic researchers, funding agencies, and pharmaceutical representatives gathered: (i) to assess the status of herpes vaccine research; and (ii) to identify the gaps and propose alternative approaches in developing a safe and efficient herpes vaccine. One “common denominator” among previously failed clinical herpes vaccine trials is that they either used a whole virus or whole viral proteins, which contain both pathogenic “symptomatic” and protective “asymptomatic” antigens/epitopes. In this report, we continue to advocate that using an “asymptomatic” epitope-based vaccine strategy that selectively incorporates protective epitopes which: (i) are exclusively recognized, in vitro, by effector memory CD4+ and CD8+ TEM cells from “naturally” protected seropositive asymptomatic individuals; and (ii) protect, in vivo, human leukocyte antigen (HLA) transgenic animal models from ocular and genital herpes infections and diseases, could be the answer to many of the scientific challenges facing HSV vaccine

    To provide guidelines for the management of woman with genital herpes during pregnancy or labor and with known history of genital herpes. MedLine and Cochrane Library databases search and review of the main foreign guidelines. Genital herpes ulceration during pregnancy in a woman with history of genital herpes correspond to a recurrence. In this situation, there is no need for virologic confirmation (Grade B). In case of recurrent herpes during pregnancy, antiviral therapy with acyclovir or valacyclovir can be administered but provide low efficiency on duration and severity of symptoms (Grade C). Antiviral treatment proposed is acyclovir (200mg 5 times daily) or valacyclovir (500mg twice daily) for 5 to 10 days (Grade C). Recurrent herpes is associated with a risk of neonatal herpes around 1% (LE3). Antiviral prophylaxis should be offered for women with recurrent genital herpes during pregnancy from 36 weeks of gestation and until delivery (Grade B). There is no evidence of the benefit of prophylaxis in case or recurrence only before the pregnancy. There is no recommendation for systematic prophylaxis for women with history of recurrent genital herpes and no recurrence during the pregnancy. At the onset of labor, virologic testing is indicated only in case of genital ulceration (Professional consensus). In case of recurrent genital herpes at the onset of labor, cesarean delivery will be all the more considered if the membranes are intact and/or in case of prematurity and/or in case of HIV positive woman and vaginal delivery will be all the more considered in case of prolonged rupture of membranes after 37 weeks of gestation in an HIV negative woman (Professional consensus). In case of recurrent genital herpes at the onset of labor and intact membranes, cesarean delivery should be considered. In case of recurrent genital herpes and prolonged rupture of membranes at term, the benefit of cesarean delivery is more questionable and vaginal delivery should be considered

  15. Disease burden of herpes zoster in Sweden - predominance in the elderly and in women - a register based study

    Science.gov (United States)

    2013-01-01

    Background The herpes zoster burden of disease in Sweden is not well investigated. There is no Swedish immunization program to prevent varicella zoster virus infections. A vaccine against herpes zoster and its complications is now available. The aim of this study was to estimate the herpes zoster burden of disease and to establish a pre-vaccination baseline of the minimum incidence of herpes zoster. Methods Data were collected from the Swedish National Health Data Registers including the Patient Register, the Pharmacy Register, and the Cause of Death Register. The herpes zoster burden of disease in Sweden was estimated by analyzing the overall, and age and gender differences in the antiviral prescriptions, hospitalizations and complications during 2006-2010 and mortality during 2006-2009. Results Annually, 270 per 100,000 persons received antiviral treatment for herpes zoster, and the prescription rate increased with age. It was approximately 50% higher in females than in males in the age 50+ population (rate ratio 1.39; 95% CI, 1.22 to 1.58). The overall hospitalization rate for herpes zoster was 6.9/100,000 with an approximately three-fold increase for patients over 80 years of age compared to the age 70-79 group. A gender difference in hospitalization rates was observed: 8.1/100,000 in females and 5.6/100,000 in males. Herpes zoster, with a registered complication, was found in about one third of the hospitalized patients and the most common complications involved the peripheral and central nervous systems. Death due to herpes zoster was a rare event. Conclusions The results of this study demonstrate the significant burden of herpes zoster disease in the pre-zoster vaccination era. A strong correlation with age in the herpes zoster- related incidence, hospitalization, complications, and mortality rates was found. In addition, the study provides further evidence of the female predominance in herpes zoster disease. PMID:24330510

    Herpes simplex virus type 1 (HSV-1) has been associated with the genesis of leukoplakias, epithelial atypia, and oral cancer. Tobacco habits, such as snuff dipping, are also definitely correlated with this type of lesion. The normal cytolytic HSV-1 infection can, after in vitro inactivation, transform cells. Extracts of snuff were prepared and assayed for their ability to inhibit HSV-1 replication. Plaque formation assays of HSV-1 in the presence of snuff extract showed that a reduced number of plaques was formed. Different batches of one brand of snuff were tested for inhibition of herpes simplex virus (HSV) production. More than 99% inhibition of 24-hr HSV production was obtained with undiluted batches. The 1:5 dilutions of snuff had an inhibitory effect of 85% and 1:25 dilutions, 39%. In agreement, the attachment of the virus to the host cell and penetration of the virus to the cell nuclei were found to be inhibited as was the synthesis of viral DNA. Nicotine had an inhibitory effect, while aromatic additions to snuff were found to have no major inhibitory effect on HSV replication. Snuff extracts were prepared from different brands of snuff reported to contain high and low quantities of tobacco-specific N-nitrosamines. Brands with reported high levels of tobacco-specific N-nitrosamines had significantly greater ability to inhibit HSV replication. In conclusion, this study has shown that extracts of snuff have inhibitory effects on the production of cytolytic HSV-1 infections. A chronic snuff dipper keeps tobacco in the mouth for the major part of the day. Thus, virus shed in the oral cavity in connection with a reactivated latent HSV-1 infection has great possibilities of being affected by snuff or derivatives of snuff. It is suggested that an interaction between tobacco products and HSV-1 might be involved in the development of dysplastic lesions in the oral cavity.

    PURPOSE: To report a case of posterior ischemic optic neuropathy (PION following herpes zoster ophthalmicus (HZO. CASE REPORT: A 58-year-old woman with history of recent HZO in her right eye presented with acute painless loss of vision in the same eye to no light perception. Examination revealed a positive relative afferent pupillary defect and a normal appearing optic disc. Inflammatory and infiltrative lesions of the optic nerve were ruled out by laboratory and imaging studies. The patient received systemic acyclovir and prednisolone. Three months later, visual acuity improved to counting fingers, but the optic disc became pale and atrophic leading to a presumptive diagnosis of PION. Considering the positive PCR test for varicella zoster virus and the short time interval between the two presentations, HZO was considered as the most probable cause of the optic neuropathy. CONCLUSION: Herpes zoster ophthalmicus can be associated with PION.

    Herpes simplex virus (HSV) is the most common causative pathogen of nonepidemic encephalitis in Japan. The mortality rate is approximately 30% and surviving patients often have severe sequelae such as amnestic syndrome. Between 1979 and 1992, 13 patients with herpes simplex encephalitis (HSE) were admitted to our Department. Diagnosis was based on the neurological symptoms and signs, the findings on EEG, CT and MRI, and the results of serological examination including ELISA for HSV type 1. Neuropsychological tests were performed over a period of approximatly 2 years in seven of 13 patients. The results of the tests disclosed memory impairments as follows. Namely, immediate recall was well preserved, but disturbance of recent memory and retrograde amnesia over 20 years were observed. The neuropsychological features more closely resembled those of amnestic syndrome than those of Korsakoff syndrome. The amnesia in HSE patients was characterized in the finding that it was prone to recover more gradually as compared with that following head trauma or surgical brain resection. CT scan was performed in 13 patients during the acute and convalescent stages. The low density areas were found in the temporal lobes in 60% of the patients. MRI were obtained during the convalescent stage in ten of 13 patients. In seven of the ten patients, abnormal signals were distributed uni- or bilaterally to the temporal lobe, insular and limbic system such as the hippocampus and amygdala. In the remaining three patients, the abnormal signals were localized in both hippocampi and amygdalae in one patient and only in the brain stem in another. In the last case, the MRI was normal. The findings that signal intensity on MRI showing the lesion in the temporal lobe spread continuously to the opposite limbic area or occipital lobe strongly suggested the spreading of HSV through neural fiber connections in HSE.

    The effects of photodynamic action on in vitro herpes simplex virus infections of CV-1 monkey kidney fibroblasts or human skin fibroblasts were determined using proflavine sulfate and white fluorescent lamps. Photodynamic treatment of confluent cell monolayers prior to virus infection inactivated cell capacity, i.e. the capacity of the treated cells to support subsequent virus growth as measured by plaque formation. The capacity of human cells was more sensitive to inactivation than the capacity of monkey cells when 6 μM proflavine was used. Treated cell monolayers recovered the capacity to support virus plaque formation when virus infection was delayed four days after the treatment. Experiments in which the photodynamically treated monolayers were infected with UV-irradiated virus demonstrated that this treatment induced Weigle reactivation in both types of cells. This reactivation occurred for virus infection just after treatment or 4 days later. A Luria-Latarjet-type experiment was also performed in which cultures infected with unirradiated virus were photodynamically treated at different times after the start of infection. The results showed that for the first several hours of the virus infection the infected cultures were more sensitive to inactivation by photodynamic treatment than cell capacity. By the end of the eclipse period the infected cultures were less sensitive to inactivation than cell capacity. Results from extracellular inactivation of virus growth in monkey cells at 6 μM proflavine indicated that at physiological pH the virus has a sensitivity to photodynamic inactivation similar to that for inactivation of cell capacity. The combined data indicated that photodynamic treatment of the cell before or after virus infection could prevent virus growth. Thus, photodynamic inactivation of infected and uninfected cells may be as important as inactivation of virus particles when considering possible mechanisms in clinical photodynamic therapy for herpes

    The epidemiology of cutaneous herpes simplex infection (CHSI) has dramatically changed over the past several decades. Valaciclovir is one of a new generation of antiviral medications that has expanded treatment options for the most common cutaneous manifestations of herpes simplex virus. However, the efficacy and safety of formulations with different doses of valaciclovir remain unclear. To carry out hospital risk management by ascertaining the incidence and risk of CHSI in patients during treatment with varying doses of valaciclovir. The PubMed, MEDLINE and Web of Science electronic databases were systematically searched from database inception to date of searching. Efficacy of drug treatment was measured by average easement score (AES). Safety was characterized as the proportion of patients with drug adverse reactions (DARs) such as fever, dizziness, headache, anxiety, irritability and yellowing of the skin. Outcomes for continuous and dichotomous data were estimated by standard mean difference (SMD) and risk ratio (RR), respectively. Five randomized controlled trials involving 1753 randomized participants for efficacy assessment and 1874 randomized participants for safety assessment were identified. Valaciclovir dose increasing from 1000 mg/day improved AES only moderately, but significantly promoted the incidence of DARs. Twice-daily treatment showed no increase in therapeutic effect but greatly increased DAR incidence. The valaciclovir dose that produced a reduction in AES was 1000 mg/day: SMD = -0.73 (95% CI -0.98 to 0.48; P < 0.01) and RR = 0.95 (95% CI 0.81-1.09; P < 0.002). Increasing the daily dose of valaciclovir does not substantially improve therapeutic efficacy for CHSI but may raise DAR incidence. Drug doses of 1000 and 2000 mg/day show no significant difference in efficacy scores, but the latter exhibits a higher incidence of DARs. The dose-dependent, long-term efficacy and safety of valaciclovir remain to be explored. © 2016 British Association of

    Full Text Available Herpes simplex encephalitis (HSE is a rare complication of Herpes simplex virus type-1 infection. It results in severe parenchymal damage in the brain. Although viral latency in neurons is very common in the population, it remains unclear why certain individuals develop HSE. Here we explore potential host genetic variants predisposing to HSE. In order to investigate this we used a rat HSE model comparing the HSE susceptible SHR (Spontaneously Hypertensive Rats with the asymptomatic infection of BN (Brown Norway. Notably, both strains have HSV-1 spread to the CNS at four days after infection. A genome wide linkage analysis of 29 infected HXB/BXH RILs (recombinant inbred lines-generated from the prior two strains, displayed variable susceptibility to HSE enabling the definition of a significant QTL (quantitative trait locus named Hse6 towards the end of chromosome 4 (160.89-174Mb containing the Vwf (von Willebrand factor gene. This was the only gene in the QTL with both cis-regulation in the brain and included several non-synonymous SNPs (single nucleotide polymorphism. Intriguingly, in human chromosome 12 several SNPs within the intronic region between exon 43 and 44 of the VWF gene were associated with human HSE pathogenesis. In particular, rs917859 is nominally associated with an odds ratio of 1.5 (95% CI 1.11-2.02; p-value = 0.008 after genotyping in 115 HSE cases and 428 controls. Although there are possibly several genetic and environmental factors involved in development of HSE, our study identifies variants of the VWF gene as candidates for susceptibility in experimental and human HSE.

    The few existing studies on herpes labialis among health care workers have been predominantly among non-dental health care workers. The purpose of this study was to determine Nigerian dental health care providers' knowledge of, attitudes toward, preventive behaviors for, and refusal to treat patients with herpes labialis. This cross-sectional study was conducted among final-year dental students at the University of Benin, dental house officers, and residents at the University of Benin Teaching Hospital, Benin City, Nigeria. Data collection was via a self-administered questionnaire. Bivariate statistics and logistic regression were used to relate the dependent and independent variables. Of the 120 questionnaires distributed, 110 were completed and returned, giving a 91.7% retrieval rate. However, 15 of the returned questionnaires were discarded because they were improperly completed, leaving a total of 95 questionnaires for final analysis in this study. The majority of participants were over 28 years old (54.7%), male (67.4%), unmarried (66.3%), and postgraduate dental health care providers (51.6%). Less than half (43.2%) of participants demonstrated adequate overall knowledge of herpes labialis. About one-tenth (10.5%) and more than three-quarters (87.4%) of participants reported a positive attitude and performance of adequate preventive behaviors, respectively. A total of 16.8% of participants reported a high tendency to refuse treatment to patients with herpes labialis. Although not statistically significant, young, unmarried, male undergraduate participants reported a greater likelihood to refuse treatment to herpes labialis patients. We found a statistically significant positive correlation between attitude and refusal to treat patients with herpes labialis. However, marital status and the attitude of participants toward these patients emerged as the determinants for refusal to treat patients with herpes labialis. Data from this study revealed a high level of

    Full Text Available AIM: To investigate whether DNA vaccine encoding herpes simplex virus 1 (HSV-1 glycoprotein C (gC and glycoprotein D (gD will achieve better protective effect against herpes simplex keratitis (HSK than DNA vaccine encoding gD alone. METHODS: DNA vaccine expressing gD or gC combined gD (gD.gC were constructed and carried by chitosan nanoparticle. The expression of fusion protein gD and gC were detected in DNA/nanoparticle transfected 293T cells by Western-blot. For immunization, mice were inoculated with DNA/nanoparticle for 3 times with 2wk interval, and two weeks after the final immunization, the specific immune responses and clinical degrees of primary HSK were evaluated. RESULTS: Fusion protein gD.gC could be expressed successfully in cultured 293T cells. And, pRSC-gC.gD-IL21 DNA/chitosan nanoparticle could effectively elicit strongest humoral and cellular immune response in primary HSK mice evidenced by higher levels of specific neutralizing antibody and sIgA production, enhanced cytotoxicities of splenocytes and nature killer cells (NK, when compared with those of gD alone or mocked vaccine immunized mice. As a result, gC-based vaccine immunized mice showed least HSK disease. CONCLUSION: gC-based DNA vaccine could effectively prevent the progress of primary HSK, suggesting that this DNA vaccine could be a promising vaccine for HSK treatment in the future.

    Herpes simplex virus type 1 (HSV-1) is isolated principally from the upper half of the body innervated by the trigeminal ganglia whereas herpes simplex virus type 2 (HSV-2) is generally isolated from the lower half of the body innervated by the sacral ganglia. However, recent reports suggest that HSV-1 and HSV-2 can each infect both the upper and lower half of the body causing a variety of symptoms and there is a possibility that HSV-1 and HSV-2 infections can occur simultaneously with both causing symptoms. HSV type in clinical isolates from 87 patients with genital herpes and 57 with ocular herpes was determined by the polymerase chain reaction (PCR), and six cases of mixed infection with both HSV-1 and HSV-2 were identified. Of the six cases, three were patients with genital herpes and three were ocular herpes patients. Analysis of the copy number of the HSV-1 and HSV-2 genome by a quantitative real time PCR demonstrated that HSV-1 was dominant at a ratio of approximately 100:1 in the ocular infections. In contrast, the HSV-2 genome was present at a 4-40 times higher frequency in isolates from genital herpes patients. There was no obvious difference between the clinical course of mixed infection and those of single HSV-1 or HSV-2 infections. This study indicated that the frequency of mixed infection with both HSV-1 and HSV-2 is comparatively higher than those of previous reports. The genome ratio of HSV-1 and HSV-2 reflects the preference of each HSV type for the target organ.

En ambos tipos de pitahayas, se realizaron autopolinizaciones y polinizaciones cruzadas directas y recíprocas, con el propósito de evaluar el efecto en la cantidad de frutos que lograron su desarrollo. Se midieron algunas variables para detectar la influencia del progenitor paterno en algunas características del fruto. Los testigos se obtuvieron de flores polinizadas libremente. El diseño experimental utilizado fue completamente al azar, con 15 repeticiones por tratamiento. Se encontró que Uqroo1 es autocompatible, mientras que Uqroo2 es autoincompatible. Los testigos de ambos tipos alcanzaron el mismo peso, y los frutos de Uqroo2 logrados por polinización cruzada tuvieron un peso similar al de los testigos o fueron significativamente mas pesados.

    General practitioners frequently encounter skin diseases and are accustomed to diagnosing the most common dermatologic conditions. We sought to determine the most common dermatologic topics published in five high-impact general medical journals (New England Journal of Medicine, The Lancet, the Journal of the American Medical Association, British Medical Journal (now The BMJ), and Annals of Internal Medicine). We conducted an independent search of the Thomson Reuters’ Science Citation Index for common dermatologic topics, limited to the period 1970 to 2012. Total number of publications dealing with each dermatologic topic considered. The five most common dermatologic topics published were melanoma, psoriasis, herpes simplex, herpes zoster, and acne. Melanoma and psoriasis were the top two dermatologic topics published in each journal except for Annals of Internal Medicine. Internists frequently diagnose herpes simplex, herpes zoster, and acne, which are also common dermatologic topics published. Although internists infrequently diagnose melanoma and psoriasis, they are major topics for general medical journals because of their increased community awareness, major advancements in therapeutic research, and their nondermatologic manifestations.

They are selectively replication-competent viruses that propagate only in actively dividing tumor cells but not in normal cells and, as a result, destroy the tumor cells by consequence of lytic infection. At least six different oncolytic herpes simplex viruses (oHSVs have undergone clinical trials worldwide to date, and they have demonstrated an excellent safety profile and intimations of efficacy. The first pivotal Phase III trial with an oHSV, talimogene laherparepvec (T-Vec [OncoVexGM-CSF], is almost complete, with extremely positive early results reported. Intuitively, therapeutically beneficial interactions between oHSV and chemotherapeutic and targeted therapeutic drugs would be limited as the virus requires actively dividing cells for maximum replication efficiency and most anticancer agents are cytotoxic or cytostatic. However, combinations of such agents display a range of responses, with antagonistic, additive, or, perhaps most surprisingly, synergistic enhancement of antitumor activity. When synergistic interactions in cancer cell killing are observed, chemotherapy dose reductions that achieve the same overall efficacy may be possible, resulting in a valuable reduction of adverse side effects. Therefore, the combination of an oHSV with “standard-of-care” drugs makes a logical and reasonable approach to improved therapy, and the addition of a targeted oncolytic therapy with “standard-of-care” drugs merits further investigation, both preclinically and in the clinic.

    Herpes simplex virus (HSV) lesions are prone to reactivation and recurrence in response to various local or systemic triggering factors. To study the characteristics of five bedridden geriatric patients who presented with herpetic recurrences on the buttocks, gluteal cleft, and perianal region during hospitalization. Data were gathered regarding age, gender, reason for hospitalization, localization of lesions, clinical presentation, previous clinical diagnosis and topical treatments, immune status and immunosuppressant drug intake, as well as prior history of labial or genital herpes. A skin biopsy was taken for histologic examination and immunohistochemical viral identification. Viral culture and viral serology were performed and data regarding antiviral therapy were recorded. The five patients (three women, two men) were aged >80 years and hospitalized for either severe drug-induced renal insufficiency (one case), severe pneumonia (two cases), or stroke causing restricted mobility (two cases). Numerous well demarcated, painful ulcerations developed in the perianal region of these patients, and one patient also presented with some vesicular lesions. The lesions had been confused with mycotic and/or bacterial infections for 10-14 days. No inguinal lymphadenopathies were present and there was no fever. None of the patients had a previous history of recurrent labial or genital HSV infections or HIV infection. Histology was suggestive of HSV infection in two of five patients. Immunohistochemistry identified HSV type I (three patients) and HSV type II (two patients) infections. Viral culture with immunofluorescence viral identification revealed HSV type I in one of the four patients in whom a swab for viral culture was taken. Serology revealed past HSV infection. All lesions cured gradually after 10-14 days of intravenous acyclovir (aciclovir) treatment. Herpetic lesions of the perineal region represent a rare complication in bedridden geriatric patients in the absence

    Herpes simplex keratitis is commonly caused by Herpes simplex virus type 1, which primarily infects eyelids, corneas, or conjunctiva. Herpes simplex virus type 1-through sophisticated interactions with dendritic cells (DCs), a type of antigen-presenting cell)-initiates proinflammatory responses in the cornea. Corneas were once thought to be an immune-privileged region; however, with the recent discovery of DCs that reside in the cornea, this long-held conjecture has been overturned. Therefore, evaluating the clinical, preclinical, and cell-based studies that investigate the roles of DCs in corneas infected with Herpes simplex virus is critical. With in vivo confocal microscopy, animal models, and cell culture experiments, we may further the understanding of the sophisticated interactions of Herpes simplex virus with DCs in the cornea and the molecular mechanism associated with it. It has been shown that specific differentiation of DCs using immunohistochemistry, flow cytometry, and polymerase chain reaction analysis in both human and mice tissues and viral tissue infections are integral to increasing understanding. As for in vivo confocal microscopy, it holds promise as it is the least invasive and a real-time investigation. These tools will facilitate the discovery of various targets to develop new treatments.

    Herpes zoster is a common illness that can lead to serious morbidity. There is now evidence that HIV-infected patients who have been treated with antiretroviral therapy are at greater risk of developing herpes zoster not when they are severely immunocompromised but, paradoxically, when their immune system is recovering. This is a manifestation of the immune reconstitution inflammatory syndrome. The objectives of this report are to (1) inform health care providers that HIV-infected patients may develop multiple infectious, autoimmune, and oncological manifestations after treatment with antiretroviral medication, as they have immune system reconstitution, and (2) discuss herpes zoster, one of the possible manifestations. The patient is a 68-year-old HIV-positive man who presented with herpes zoster after being treated with highly active antiretroviral therapy (HAART) when his immune system was recovering, not when he was most immunosuppressed. Emergency department physicians should be aware that HIV-infected patients treated with HAART may have clinical deterioration despite immune system strengthening. This immune reconstitution inflammatory syndrome can present with infectious, autoimmune, or oncological manifestations. Our case patient, an HIV-positive man with immune system recovery after treatment with HAART, presented with an infectious manifestation, herpes zoster.

  4. Functional decline and herpes zoster in older people: an interplay of multiple factors.

    Science.gov (United States)

    2015-12-01

    Herpes zoster is a frequent painful infectious disease whose incidence and severity increase with age. In older people, there is a strong bidirectional link between herpes zoster and functional decline, which refers to a decrement in ability to perform activities of daily living due to ageing and disabilities. However, the exact nature of such link remains poorly established. Based on the opinion from a multidisciplinary group of experts, we here propose a new model to account for the interplay between infection, somatic/psychiatric comorbidity, coping skills, polypharmacy, and age, which may account for the functional decline related to herpes zoster in older patients. This model integrates the risk of decompensation of underlying disease; the risk of pain becoming chronic (e.g. postherpetic neuralgia); the risk of herpes zoster non-pain complications; the detrimental impact of herpes zoster on quality of life, functioning, and mood; the therapeutic difficulties due to multimorbidity, polypharmacy, and ageing; and the role of stressful life events in the infection itself and comorbid depression. This model underlines the importance of early treatment, strengthening coping, and vaccine prevention.

    Full Text Available Herpes zoster ophthalmicus and HIV are serious health problems. We report a case of a 37-year-old woman who presented to the Korle-Bu Teaching Hospital with dyspnea and facial cellulitis, and a diagnosis 5 days prior of dental cellulitis made at a district hospital. Investigations revealed that the facial cellulitis was secondary to herpes zoster infection involving the ophthalmic division of the left trigeminal nerve. The patient responded well to oral acyclovir but developed postherpetic neuralgia. During the course of treatment, she was also diagnosed to be HIV-1 positive and was referred for further management. This case represents a unique report in which the patient presented to the hospital with symptoms of cellulitis suggestive of underlying dental infection but was later diagnosed with both herpes zoster ophthalmicus and an underlying HIV infection. Atypical presentations of herpes zoster can occur in HIV/AIDS. Signs of herpes zoster infection with cellulitis should alert the clinician that the patient may have a possible underlying immunosuppressive disease. The population must be educated regarding the importance of early presentation and careful compliance with treatment as well as regular follow-ups.

    Background The incidence and risk factors for herpes zoster have been studied in cross-sectional and cohort studies, although most such studies have been conducted in Western countries. Evidence from Asian populations is limited, and no cohort study has been conducted in Asia. We are conducting a 3-year prospective cohort study in Shozu County in Kagawa Prefecture, Japan to determine the incidence and predictive and immunologic factors for herpes zoster among Japanese. Methods The participants are followed for 3 years, and a telephone survey is conducted every 4 weeks. The participants were assigned to 1 of 3 studies. Participants in study A gave information on past history of herpes zoster and completed health questionnaires. Study B participants additionally underwent varicella-zoster virus (VZV) skin testing, and study C participants additionally underwent blood testing. If the participants develop herpes zoster, we evaluate clinical symptoms, measure cell-mediated immunity and humoral immunity using venous blood sampling, photograph skin areas with rash, conduct virus identification testing by polymerase chain reaction (PCR) and virus isolation from crust sampling, and evaluate postherpetic pain. Results We recruited 12 522 participants aged 50 years or older in Shozu County from December 2009 through November 2010. The participation rate was 65.7% of the target population. Conclusions The present study is likely to provide valuable data on the incidence and predictive and immunologic factors for herpes zoster in a defined community-based population of Japanese.

    Herpes simplex virus (HSV) is one of the three major causes of infectious esophagitis, along with Candida albicans and Cytomegalo virus (CMV). Most cases occur in immunocompromised hosts, in whom this can be life threatening. We report two cases of herpes simplex esophagitis occurring during treatment for lung cancer. An 80-year-old man with radiation pneumonia caused by radiotherapy for lung cancer was admitted for treatment with antibiotics and corticosteroids. Shortly after initiation of treatment, he complained of dysphasia. Endoscopic examination revealed herpes simplex esophagitis. A 71-year-old man was given corticosteroids for cryptogenic organizing pneumonia following chemotherapy for lung cancer. During treatment, the patient complained of odynophagia. Endoscopic examination revealed herpes simplex esophagitis. Both cases died due to progression of lung cancer and acute respiratory distress syndrome, despite administration of acyclovir. When immunocompromised patients complain of prolonged dysphagia and odynophagia, the presence of herpes simplex esophagitis should be clarified by endoscopic examination. It is occasionally difficult to distinguish between HSV and Candida esophagitis by endoscopic observation alone. Esophageal mucosal endoscopic cytology can help differentiate between these three infectious agents. (author)

    The herpes virus can be found anywhere and one of the important characteristics is its ability to cause acute and chronic infection at certain times so as a result of the infection allows severe complications occurred. The herpes virus is composed of DNA containing protein and wrapped by glycoproteins. In this work, the Herpes viruses family is classified and analyzed by clustering their protein-sequence using Tribe Markov Clustering (Tribe-MCL) algorithm. Tribe-MCL is an efficient clustering method based on the theory of Markov chains, to classify protein families from protein sequences using pre-computed sequence similarity information. We implement the Tribe-MCL algorithm using an open source program of R. We select 24 protein sequences of Herpes virus obtained from NCBI database. The dataset consists of three types of glycoprotein B, F, and H. Each type has eight herpes virus that infected humans. Based on our simulation using different inflation factor r=1.5, 2, 3 we find a various number of the clusters results. The greater the inflation factor the greater the number of their clusters. Each protein will grouped together in the same type of protein.

    Herpes zoster (shingles) is caused when the varicella zoster virus that has remained latent since an earlier varicella infection (chicken-pox) is reactivated. Herpes Zoster is a less common and endemic disease than varicella: factors causing reactivation are still not well known, but it occurs in older and/or immunocompromised individuals. Following reactivation, centrifugal migration of herpes zoster virus (HZV) occurs along sensory nerves to produce a characteristic painful cutaneous or mucocutaneous vesicular eruption that is generally limited to the single affected dermatome. Herpes zoster may affect any sensory ganglia and its cutaneous nerve: the most common sites affected are thoracic dermatomes (56%), followed by cranial nerves (13%) and lumbar (13%), cervical (11%) and sacral nerves (4%). Among cranial nerves, the trigeminal and facial nerves are the most affected due to reactivation of HZV latent in gasserian and geniculated ganglia. The 1st division of the trigeminal nerve is commonly affected, whereas the 2nd and the 3rd are rarely involved. During the prodromal stage, the only presenting symptom may be odontalgia, which may prove to be a diagnostic challenge for the dentist, since many diseases can cause orofacial pain, and the diagnosis must be established before final treatment. A literature review of herpes zoster of the trigeminal nerve is presented and the clinical presentation, differential diagnosis and treatment modalities are underlined. A case report is presented.

    Full Text Available BACKGROUND: Infections of the skin by herpes viruses do not always present themselves in typical fashion. Early diagnosis, however, is crucial for appropriate treatment. Polymerase chain reaction (PCR allows diagnosis and differential diagnosis of herpes virus infections, but the method is not yet available in large parts of the world, where diagnosis is made based on morphology alone. AIM: To refine criteria for the diagnosis of herpes virus infections of the skin by way of correlation of clinical and histopathologic findings with results of PCR studies. METHODS: We studied 75 clinically diagnosed patients of "zoster," "varicella," and "herpes simplex", to correlate clinical and histopathological findings with results of PCR studies on paraffin embedded biopsy specimens. RESULTS: Clinical suspicion of infection by herpes viruses was confirmed by histopathology in 37% of the cases and by PCR studies in 65% of the cases. Zoster was frequently misdiagnosed as infection with herpes simplex viruses (30%. When diagnostic signs of herpes virus infection were encountered histopathologically, PCR confirmed the diagnosis in 94%. By way of correlation with results of PCR studies, initial lesions of herpes virus infections could be identified to have a distinctive histopathological pattern. Herpetic folliculitis appeared to be a rather common finding in zoster, it occurring in 28% of the cases. CONCLUSION: We conclude that correlation of clinical and histopathological features with results of PCR studies on one and the same paraffin embedded specimen permits identification of characteristic morphologic patterns and helps to refine criteria for diagnosis both clinically and histopathologically.

    Patients with inflammatory bowel disease (IBD) might be at increased risk for herpes zoster infection. We sought to quantify the risk of herpes zoster in patients with IBD and evaluate the effects of IBD and IBD medications on the risk of herpes zoster. We conducted 2 retrospective studies of populations of Veterans, from January 2000 through June 2016. In study 1, we compared the incidence of herpes zoster among patients with IBD receiving 5-ASA alone vs matched patients without IBD. In study 2, we compared the incidence of herpes zoster among patients with IBD treated with only 5-ASA, with thiopurines, with antagonists of tumor necrosis factor (TNF), with a combination of thiopurines and TNF antagonists, and with vedolizumab. We used multivariable Cox regression to estimate the hazard ratios and 95% CIs for herpes zoster associated with IBD in study 1 and with different treatments in study 2. We also estimated the incidence rate of herpes zoster based on age and IBD medication subgroups. Compared to no IBD, ulcerative colitis (UC) and Crohn's disease (CD) were each associated with significantly increased risk of herpes zoster infection. In multivariable Cox regression (compared to no IBD), UC, CD, or IBD treated with 5-ASA treatment alone was associated with significantly increased risk of herpes zoster, with adjusted HRs (AHR) of 1.81 for UC (95% CI, 1.56-2.11), 1.56 for CD (95% CI, 1.28-1.91), and 1.72 for treated IBD (95% CI, 1.51-1.96). In multivariable Cox regression analysis, compared to exposure to 5-ASA alone, exposure to thiopurines (AHR, 1.47; 95% CI, 1.31-1.65) or a combination of thiopurines and TNF antagonists (AHR, 1.65; 95% CI, 1.22-2.23) was associated with increased risk of herpes zoster. However, exposure to TNF antagonists alone (AHR, 1.15; 95% CI, 0.96-1.38) was not associated with increased risk of herpes zoster. The incidence rates of herpes zoster in all age groups and all IBD medication subgroups were substantially higher than that in the

    We assessed cell-mediated immunity to herpes simplex virus type 1 antigen in patients suffering from recurrent cold sores and in a series of healthy controls. Paradoxically, all those subject to recurrent herpetic infections had, without exception, evidence of cell-mediated immunity to herpes antigens. This was demonstrated by lymphocyte transformation and specific 51 Cr release from infected human amnion cells after incubation with peripheral blood mononuclear cells. Where performed, skin tests with herpes antigen were also positive. In addition, serum from these patients specifically sensitized herpes virus-infected cells to killing by nonimmune, control mononuclear cells. These tests were negative in the control patients except in a few cases, and it is suggested that these latter may be the asymptomatic herpes virus carriers previously recognized or that they may have experienced a genital infection.

    Herpes simplex virus 1 (HSV-1) causes a chronic, lifelong infection in >60% of adults. Multiple recent vaccine trials have failed, with viral diversity likely contributing to these failures. To understand HSV-1 diversity better, we comprehensively compared 20 newly sequenced viral genomes from China, Japan, Kenya, and South Korea with six previously sequenced genomes from the United States, Europe, and Japan. In this diverse collection of passaged strains, we found that one-fifth of the newly sequenced members share a gene deletion and one-third exhibit homopolymeric frameshift mutations (HFMs). Individual strains exhibit genotypic and potential phenotypic variation via HFMs, deletions, short sequence repeats, and single-nucleotide polymorphisms, although the protein sequence identity between strains exceeds 90% on average. In the first genome-scale analysis of positive selection in HSV-1, we found signs of selection in specific proteins and residues, including the fusion protein glycoprotein H. We also confirmed previous results suggesting that recombination has occurred with high frequency throughout the HSV-1 genome. Despite this, the HSV-1 strains analyzed clustered by geographic origin during whole-genome distance analysis. These data shed light on likely routes of HSV-1 adaptation to changing environments and will aid in the selection of vaccine antigens that are invariant worldwide. PMID:24227835

    Human embryonic fibroblasts infected with u.v.-irradiated herpes simplex virus type 2 (HSV-2, strain 186) and maintained at 40.5 0 C did not yield detectable virus. Virus synthesis was induced by temperature shift-down to 36.5 0 C. The induced virus grew very poorly and was inactivated very rapidly at 40.5 0 C. Non-irradiated virus failed to establish latency at 40.5 0 C in infected cells. Enhanced reactivation of HSV-2 was observed when latently infected cultures were superinfected with human cytomegalovirus (HCMV) or irradiated with a small dose of u.v. light at the time of temperature shift-down. HCMV did not enhance synthesis of HSV-2 during a normal growth cycle but did enhance synthesis of u.v.-irradiated HSV-2. These observations suggest that in this in vitro latency system, some HSV genomes damaged by u.v. irradiation were maintained in a non-replicating state without being destroyed or significantly repaired.
