    Full Text Available From January 1988 to January 1989 all the heart transplant and bone marrow recipients at the Instituto do Coração of the Hospital das Clínicas of the University of São Paulo Medical School were studied for the incidence and morbidity associated with herpesviruses infections after transplantation. Five bone marrow and 5 heart transplant recipients were followed for a mean of 4.2 months post-transplantation. All the patients were seropositive for cytomegalovirus (CMV before admission and 80% experienced one or more recurrences during the observation period. Of the 12 episodes of CMV infection, that were identified in this study, 83% were accompanied by clinical or laboratory abnormalities. However, there was only one case of severe disease. The overall incidence of infection for herpes simplex (HSV was 50%. Although most of HSV reactivations were oral or genital, one case of HSV hepatitis occurred. One of the 6 episodes of HSV infections that were treated with acyclovir showed an unsatisfactory response and was successfully managed with ganciclovir. All the individuals had anti-varicella zoster virus antibodies, but none of them developed infection. The study emphasizes the importance of active diagnostic surveillance of herpesvirus infections in transplant patients. Both CMV and HSV reactivations showed high incidence and important morbidity and thus, deserve prophylactic therapy.De janeiro de 1988 a janeiro de 1989 todos os pacientes submetidos a transplante de coração ou de medula óssea no Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo foram estudados quanto à incidência e morbidade das infecções pós-transplante causadas por vírus do grupo herpes. Cinco recipientes de medula óssea e 5 transplantados cardíacos foram observados por um período médio de 4.2 meses após o transplante. Todos os pacientes tinham sorologia positiva para citomegalovírus (CMV antes do transplante

    2007-02-01

    Full Text Available A infecção por Herpes simplex vírus (HSV é causa freqüente de inflamação intra-ocular ou uveíte anterior. A hipertensão ocular é característica comumente observada nas ceratouveítes herpéticas. Neste relato descrevemos o acúmulo de fluido e descolamento do "flap" corneano da ceratomileusis, no pós-operatório tardio de LASIK (28 meses, associado a quadro hipertensivo ocular secundário a ceratouveíte herpética. Este achado corrobora a suposição que a cicatrização corneana após LASIK seja apenas parcial e o espaço virtual produzido pela ceratomileuisis permaneça indefinidamente. Condições de aumento excessivo da pressão intra-ocular podem causar edema corneano com acúmulo de fluido da interface.Herpes simplex virus infection is a frequent cause of intraocular inflammation or anterior uveitis. Ocular hypertension is a common feature in herpetic keratouveitis. We describe a fluid accumulation and flap displacement in late postoperative period (28 months of LASIK associated with ocular hypertension caused by herpetic keratouveitis. This finding supports the theory that flap attachment after LASIK is only partial and the virtual space remains indefinitely. The presence of ocular hypertension may lead to corneal edema and fluid accumulation in the interface.

  16. Mastite bovina causada por Staphylococcus spp. resistentes à meticilina: revisão de literatura

    Directory of Open Access Journals (Sweden)

    José Givanildo Silva

    Full Text Available RESUMO: Staphylococcus spp. são os micro-organismos mais relacionados a casos de mastite bovina. Algumas cepas destes micro-organismos têm apresentado fatores de virulência como genes de resistência a antimicrobianos com destaque para a resistência à meticilina que é um problema de saúde pública. Esta revisão de literatura tem o objetivo de compilar dados sobre a mastite bovina causada por Staphylococcus spp. resistente à meticilina (MRS. Apesar desse antimicrobiano não ser comumente utilizado no tratamento das mastites, a frequência de casos de infecção da glândula mamária causada por MRS tem variado entre 1,34 a 47,6%. Acredita-se que o contato dos humanos com animais positivos para MRS e vice-versa favoreça a transmissão deste patógeno entre as espécies, contribuindo para a variação nas taxas de infecção. A detecção de MRS pode ser realizada por meio de provas fenotípicas, moleculares ou sorológicas e as medidas de controle devem contemplar a identificação dos casos, segregação dos animais, estudo epidemiológico da fonte de infecção do rebanho, além da constante limpeza e higienização do ambiente de confinamento, equipamentos e utensílios de ordenha. Casos de mastite ocasionados por esse patógeno assumem relevância para a saúde pública, pois a ingestão de leite e/ou derivados contaminados podem desencadear a transferência de MRS para seres humanos. Com isso, é necessário um alerta constante quanto à vigilância epidemiológica em fazendas leiteiras.

    Full Text Available Esta pesquisa teve como objetivo avaliar a corrosividade de soluções preservativas preparadas com creosoto vegetal. Por destilação do alcatrão vegetal, obteve-se o creosoto vegetal bruto, recuperado à temperatura de 110-255 masculineC. Uma fração deste destilado foi lavada com solução a 9% de bicarbonato de sódio, obtendo-se o creosoto vegetal purificado. Ambas as frações foram enriquecidas com 3% de naftenato de cobre; 3% de naftenato de zinco; 3% de naftenato de cobalto; 2% de TBTO; 2% de tribromofenato de tributil-estanho; 2% de pentaclorofenol; ou 0,4% de trióxido de arsênico. Foram preparadas 16 soluções preservativas, sendo 14 enriquecidas, além do creosoto vegetal bruto e do creosoto vegetal purificado. Placas de aço SAE 1006 foram expostas por 6 horas às temperaturas de 25, 45 e 100 masculineC, à ação corrosiva dessas soluções. A corrosividade das soluções de creosoto vegetal foi comparada à corrosividade causada pelo creosoto mineral. As soluções preparadas com creosoto vegetal purificado foram menos corrosivas que suas similares preparadas com creosoto vegetal bruto, sem, no entanto, atingir a baixa corrosividade do creosoto mineral.

    Full Text Available Pudrición basal causada por Phytophthora capcisi en plantas de chile tratadas con vermicompost. El objetivo de este trabajo fue evaluar a nivel de invernadero el efecto de vermicompost sobre la incidencia y severidad de Phytophthora capcisi en plantas de chile (Capsicum annuum. Esta investigación se realizó entre febrero y marzo del 2012 en el Centro de Investigaciones Agronómicas, Sabanilla, San José, Costa Rica. Se utilizó un diseño completamente al azar con cuatro repeticiones y ocho plantas por unidad experimental en un arreglo factorial con los factores de dosis (0, 25% y 50% v/v vermicompost:suelo e inoculación (0 y 500 zoosporas por gramo de suelo. Se trasplantaron plántulas de 35 días, que fueron inoculadas dos semanas después del trasplante. La aplicación de vermicompost provocó un aumento significativo del peso fresco foliar y del peso seco foliar y radical; a mayor dosis, mayor fue el incremento. Las plantas de todos los tratamientos que incluyeron inoculación con P. capsici presentaron síntomas de la enfermedad en la raíz. Los valores de incidencia y severidad fueron mayores para el tratamiento con 50% de abono. En este tratamiento se presentaron síntomas de marchitez. La ausencia de diferencias en las variables de peso fresco y seco entre los tratamientos inoculados y sin inocular, a los que se adicionó abono al 25%, sugiere que esta dosis podría compensar el daño causado por el patógeno. Se observó una menor concentración de nutrimentos en los tejidos de las plantas inoculadas lo que indica que el daño causado a la raíz pudo haber afectado la adquisición de nutrimentos.

    Full Text Available O objetivo deste trabalho foi avaliar a incidência em várias partes da planta e o desenvolvimento da antracnose do caquizeiro causada por Colletotrichum horiinas cultivares Fuyu e Kakimel produzidas sob os sistemas orgânico e convencional, respectivamente, nas safras de 2010/2011 e 2011/2012, em Campina Grande do Sul, Paraná, Brasil. Em cada pomar, 10 plantas foram selecionadas aleatoriamente, e 10 ramos do ano por planta, distribuídos ao redor dacopa, foram marcados para as avaliações de incidência de antracnose em ramos e folhas, a cada 15 dias. A quantificação de frutos caídos com ou sem sintomas da doença foi a cada 15 dias, durante o período de crescimento de frutos até a colheita, relacionada com a produção total. C. horii em flores foi avaliada em campo e também após incubação no laboratório. Infecção latente foi observada em frutos verdes coletados aos 90; 120 e 150 dias após a floração. Em ambas as safras, observou-se a queda de frutos com sintomas de antracnose entre os meses de janeiro e abril. C. horii é capaz de infectar flores, permanecer latente e provocar sintomas de antracnose em frutos imaturos. Frutos colhidos sadios apresentaram sintomas em pós-colheita após a incubação.

    Full Text Available A ocorrência de casos esporádicos de mastite causados por microrganismos de origem ambiental pode ser considerada como emergente e as leveduras, os fungos leveduriformes e os filamentosos são alguns dos principais agentes envolvidos. Em relação à mastite micótica, as leveduras são freqüentemente causas de infecções da glândula mamária em animais produtores de leite. A maior parte dos casos ocorre sob a forma de surtos localizados e/ou após tratamento com antimicrobianos. Os principais gêneros envolvidos são Candida e Cryptococcus, além de outros como Geotrichum, Pichia e Trichosporon. O objetivo do trabalho é revisar os aspectos gerais sobre a mastite micótica causada por leveduras e fungos leveduriformes, tais como etiologia, causas predisponentes, patogenicidade, diagnóstico, tratamento e profilaxia por meio de uma abordagem cronológica dos primeiros relatos, mas com enfoque principal nos resultados descritos recentemente na literatura veterinária nacional e internacional. O controle da mastite micótica é fundamentado em métodos preventivos, como adequado manejo da ordenha, correta higienização dos equipamentos e das instalações, com a finalidade de reduzir o número de animais acometidos, além de garantir a qualidade e a inocuidade dos produtos lácteos.The veterinary literature registers sporadic cases of infections caused by environmental microorganisms in which the main agents involved are yeasts, yeasts-like and filamentous fungi. In relation to dairy animals, the yeasts are more frequently incriminated as the aetiological agents of mycotic mastitis.

    1999-09-01

    Full Text Available The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment.Os autores descrevem caso de angiostrongilíase abdominal em doente adulto que se manifestou como abdômen agudo devido à perfuração de alça jejunal, evento raro, uma vez que esta afecção geralmente envolve o íleo terminal, apêndice, ceco ou cólon ascendente. A doença é causada pelo nematódeo Angiostrongylus costaricensis cujos hospedeiros definitivos são roedores silvestres e os hospedeiros intermediários são caracóis e caramujos. A infecção em humanos é acidental e ocorre pela ingestão de secreção mucóide destes invertebrados presentes em vegetais ou por contato direto com o muco. A angiostrongilíase abdominal é clinicamente caracterizada pela presença de febre prolongada, anorexia, dor no quadrante inferior direito do abdômen e eosinofilia periférica. Embora a doença seja de

    Full Text Available Um caso de mastite clínica causada por Prototheca zopfii em uma vaca de um rebanho leiteiro localizado na Zona da Mata do Estado de Minas Gerais foi estudado. O animal apresentou sinais clínicos nos quartos mamárias anteriores e queda acentuada na produção de leite. Após o diagnóstico inicial, o animal foi observado durante onze meses, do início da manifestação da doença até 12 dias após o parto. Exames microbiológicos do leite foram realizadas aos 7, 30, 39, 49, 65, 326 e 331 dias após o isolamento inicial, sendo os dois últimos exames realizados 7 e 12 dias após o parto. As amostras de P. zopfii isoladas apresentaram resistência in vitro a: ampicilina, canamicina, cefatoridina, enrofloxacina, estreptomicina, gentamicina, neomicina, oxacilina, penicilina, sulfonamidas e trimetoprim x sulfametoxazol. Foi avaliada a susceptibilidade in vitro das amostras de P. zopfii a um produto natural constituído de extrato de sementes de frutas cítricas, obtido comercialmente. A menor concentração que inibiu totalmente a alga foi 1:500. Recomendou-se um tratamento com a diluição a 1:200 do extrato em solução fisiológica estéril contendo timerosal a 1:30.000 como conservante, em doses diárias de 20ml, por via intramamária. O tratamento foi realizado inicialmente durante sete dias. Após este período houve redução, mas não a completa eliminação dos organismos do leite. Foi, então, recomendado mais um período de 15 dias de tratamento, de modo semelhante ao primeiro. Trinta e nove dias após o diagnóstico inicial não foi mais isolado P. zopfii do leite dos quartos afetados e a produção retornou a níveis semelhantes de antes da infecção. Amostras de leite naturalmente infectadas foram congelados a -20°C. Células viáveis de P. zopfii foram recuperadas de amostras mantidas até 38 dias nestas condições.A clinical case of mastitis caused by Prototheca zopfii in a cow from a dairy herd located in the region of Zona da

    Full Text Available A podridão de raízes, causada por Pythium aphanidermatum e outras espécies de Pythium, é a principal doença da alface cultivada em sistemas hidropônicos no Brasil. O presente trabalho teve como objetivo avaliar quatro cultivares comerciais de alface em relação à sensibilidade a podridão de raízes, causada por P. aphanidermatum. Os estudos foram realizados em placas de Petri contendo ágar-água com plântulas de alface das cultivares crespa (Vera e Verônica e lisa (Regina e Elisa, infestadas ou não com o patógeno. Com as mesmas cultivares foram realizados quatro experimentos em sistemas hidropônicos (Nutrient Film Technique, sendo dois em estufa coberta com plástico e sombrite e dois em estufa coberta apenas com plástico. As plântulas, infectadas ou não com P. aphanidermatum, foram transplantadas para os sistemas infestados ou não. Foi avaliada a severidade da doença e o desenvolvimento das plantas. Todas as cultivares foram suscetíveis à podridão de raízes nos experimentos realizados in vitro e in vivo. A presença do sombrite não reduziu a podridão de raízes em cultivares de alface produzidas no sistema hidropônico. A cultivar Regina apresentou maior massa de matéria seca da parte aérea e das raízes, na presença ou ausência do patógeno, sendo a mais indicada para o cultivo hidropônico na época mais quente do ano.

Las altas tasas de choques, lesiones, muertes y discapacidad atribuidas a este problema de salud pública, representan un elevado costo para la sociedad mexicana, en especial para los hogares. Se discute cómo la respuesta mexicana se ha enfocado a los automovilistas, dejando fuera a usuarios vulnerables de la vía pública y se ha privilegiado la implementación de estrategias poco efectivas. A pesar de que se dispone de legislación para los principales factores de riesgo, se ha descuidado su correcta aplicación. La estrategia mexicana podría fortalecerse implementando estrategias de movilidad seguras, equitativas, saludables y sostenibles para los diferentes actores de la vía pública. A pesar de los avances que se han dado en términos de prevención de LCT, existen aún retos y oportunidades para el país.

    Full Text Available A compactação vem-se tornando um dos principais impactos causados ao solo pelas atividades de colheita florestal mecanizada. O peso e movimentação das máquinas no momento do corte e extração da madeira, aliados à condição de umidade do solo imprópria para tal, são as principais causas da degradação estrutural do solo, verificada, principalmente, por alterações em suas propriedades físicas. Nesse sentido, este trabalho visou identificar a compactação causada ao solo devido às operações de colheita florestal de Pinus taeda L. realizada em três diferentes níveis de umidade do terreno. O estudo foi realizado em área de uma empresa florestal localizada no Paraná sobre Latossolo Vermelho. Os tratamentos foram compostos pela interação de três fatores, sendo eles: umidade (colheita em dia chuva, três e sete dias após a chuva, operações de colheita (com passagem de máquinas, sem passagem/eventual queda de árvores e estaleiro, e a ocasião de coleta (antes e depois da colheita. A biomassa residual da colheita florestal foi essencial para minimizar a compactação do solo causada pelo tráfego das máquinas que foi próxima da máxima. A gradação de umidade representada pela colheita em diferentes números de dias após uma chuva não influenciou, de maneira diferenciada, a compactação do solo. Entretanto, as operações de colheita impactaram o solo até a profundidade de 10 cm, causando a compactação nas linhas de tráfego das máquinas, enquanto as demais operações não provocaram alterações na densidade, macroporosidade e resistência à penetração.

Un año mas tarde, en marzo de 2002, una segunda proliferación, conformada por la misma especie, se reportó cerca de Cabo Corrientes con una concentración de 1.6 x 10(6 céls l -1 . Ambos casos estuvieron relacionados con la presencia de bajas temperaturas en la superficie del mar y no estuvieron asociadas con fenómenos de intoxicación y mortalidadFrom April 26th to May 15th 2001, a large algae bloom was observed off Tumaco Bay on the Pacific coast of Colombia. This was the first harmful algae bloom (HAB reported in the region, and reached Gorgona Island, about 120 km north. Ayear later, starting March 2002, an offshore HAB developed from Cabo Corrientes North to Solano Bay. The typical abundance during the blooms reached 7.5 x 10(6 cells l-1 for the 2001 event and 1.6 x 10(6 cells l-1 for the 2002 event. During both events, low temperature and high salinity were recorded. Typical measurements in the area are 27-27.5°C and 30-31.5 psu. Values observed during the two events were 24-24.6°C and 33-34 psu; 3°C below normal and more than 2.5 psu above average values. These conditions are indicative of local upwelling processes at the time of the events. On both occasions, cells corresponding to the Alexandrium catenella/fundeyense/tamarense complex represented 99-100% of the biomass. It was difficult to differentiate the cells from A. catenella, but the presence of short chains of only 4 cells (single cells represented most of the biomass was suggestive of A. tamarense.

A soda cáustica foi o produto mais ingerido (76,2%, ingestão de ácido muriático ocorreu em três casos (14,3%, amoníaco e ácido sulfúrico em um caso (4,8% cada. RESULTADOS: As lesões faríngeas e laríngeas estiveram freqüentemente associadas às lesões de esôfago, presentes em 18 casos (85,7%. As lesões esofágicas, gástricas e duodenais foram avaliadas e classificadas por endoscopia. Lesões graves esofágicas ou gástricas estiveram presentes em cinco casos cada. CONCLUSÃO: O tratamento e os resultados foram variados, mas sugeriram que a sondagem esofágica foi prejudicial. A mortalidade global foi 28,6%, mais elevada na lesão esofágica grau 3.Treatment of chemical agent ingestion remain controversial. The incidence of these episodes has increased over the several last decades due to a variety reasons. PURPOSE: To analise the occurance, complications and results of the treatment of chemically induced esophagogastric injury. METHODS: Twenty-one adult patients with chemically induced esophagogastric injury were retrospectively studied. The patients were admitted up to 23 days after ingestion of a chemical agent to the Emergency Department of Santa Casa of Sao Paulo University Hospital from August, in a 12-year

    Full Text Available La lepra es una enfermedad infecciosa granulomatosa crónica, causada por Mycobacterium leprae . El curso natural de esta enfermedad está relacionado con una neuropatía periférica denominada neuropatía leprótica, la cual es responsable de la aparición de discapacidades en ojos, manos y pies. Se realizó una búsqueda estructurada en la base de datos de Pubmed y OVID utilizando los siguientes términos MeSH : lepra, neuropatía, nervio periférico, célula de Schwann, discapacidad, biomarcadores. El 83,8 % de los artículos referenciados en esta revisión fueron seleccionados a través de esta búsqueda. El daño neural en lepra es una patología en la que intervienen múltiples mecanismos fisiopatógenicos, que incluyen: la respuesta inmune del hospedero, la interacción de M. leprae a diferentes ligandos en las células Schwann, lo que permite la activación de vías de señalización celular que inducen inflamación, desmielinización y daños a nivel del axón, que se traducen en discapacidad sensitiva y motora en el paciente con lepra. Pero a pesar de que en las últimas décadas se han realizado avances importantes en el entendimiento de esta neuropatía, esto no se ha visto reflejado en herramientas o biomarcadores que sean útiles en la detección temprana del daño periférico causado por la lepra.

    Full Text Available Os autores relatam que durante 14 anos de trabalho clínico em campo, realizado nas comunidades de Três Braços e Corte de Pedra, Bahia, acompanharam 1.416 pacientes portadores de Leishmaniose Tegumentar Americana, cuja espécie envolvida na transmissão, é predominantemente a Leishmania Viannia brasilienses. A terapêutica utilizada rotineiramente nos casos é o antimoniato-N-metilglucamina (Glucantime. Contudo, 16 pacientes do sexo masculino recusaram-se a utilizar a medicação e 6 do sexo feminino encontravam-se em período gestacional, portanto não utilizaram o medicamento. Estes pacientes foram acompanhados por um período entre 4 a 12 anos, a partir do diagnóstico. Observou-se que em 9 pacientes (40,9% desta casuística, o tempo de cicatrizaçâo após o aparecimento da lesão, pode ser calculado em 6 meses de evolução. Quando se eleva a observação para 12 meses, temos que 19 pacientes (86,3% cicatrizaram suas lesões neste período. Em 3 casos (13,6% as lesões permaneceram ativas por mais de 12 meses. Conclui-se que os determinantes da cicatrizaçâo natural das lesões produzidas por Leishmania Viannia Braziliensis permanecem desconhecidos, dificultando para nós entendermos e compararmos aos efeitos das drogas utilizadas no tratamento da leishmaniose tegumentar.In field clinics in the comunities of Três Braços and Corte de Pedra, Bahia, we have attended 1.416 patients with tegumentary leishmaniasis in fourteen years, the predomi nant species in transmission is Leishmania Viannia brasiliensis (LVB. Because of the danger of metastasis with this infection treatment was routinely recomended with Glucantime. However sixteen patients refused injection therapy and six women were pregnant when seen and not treated. All patients were followed up in our clinic. All these patients closed their skin ulcers although one subsequently relapsed. Patients were followed up for variable periods (four to twelve years, after the diagnosis. In

    RESUMEN Introducción Las infecciones del tracto urinario (ITU) son frecuentes en la comunidad. Sin embargo, la información de aislamientos resistentes en este contexto es limitada en Latinoamérica. Este estudio tiene como objetivo determinar la prevalencia y los factores de riesgo asociados con ITU de inicio en la comunidad (ITU-IC) causadas por Escherichia coli productor de betalactamasas de espectro extendido (BLEE) en Colombia. Materiales y métodos Entre agosto y diciembre de 2011 se realizó un estudio de casos y controles en 3 instituciones de salud de tercer nivel en Colombia. Se invitó a participar a todos los pacientes admitidos a urgencias con diagnóstico probable de ITU-IC, y se les pidió una muestra de orina. En los aislamien-tos de E. coli se realizaron pruebas confirmatorias para BLEE, susceptibilidad antibiótica, caracterización molecular (PCR en tiempo real para genes bla, repetitive element palindromic PCR [rep-PCR], multilocus sequence typing [MLST] y factores de virulencia por PCR). Se obtuvo información clínica y epidemiológica, y posteriormente se realizó el análisis estadístico. Resultados De los 2.124 pacientes seleccionados, 629 tuvieron un urocultivo positivo, en 431 de estos se aisló E. coli, 54 fueron positivos para BLEE y 29 correspondieron a CTX-M-15. La mayoría de los aislamientos de E. coli productor de BLEE fueron sensibles a ertapenem, fosfomicina y amikacina. La ITU complicada se asoció fuertemente con infecciones por E. coli productor de BLEE (OR = 3,89; IC 95%: 1,10–13,89; p = 0,03). E. coli productor de CTX-M-15 mostró 10 electroferotipos diferentes; de estos, el 65% correspondieron al ST131. La mayoría de estos aislamientos tuvieron 8 de los 9 factores de virulencia analizados. Discusión E. coli portador del gen blaCTX-M-15 asociado al ST131 sigue siendo frecuente en Colombia. La presencia de ITU-IC complicada aumenta el riesgo de tener E. coli productor de BLEE, lo cual debe tenerse en cuenta para ofrecer

    Full Text Available Maize Bushy Stunt and Corn Stunt are diseases of corn caused respectively by a phytoplasma (maize bushy stunt phytoplasma and by Spiroplasma kunkelii. Both agents are restricted to the floem vessels of diseased plants. The leafhopper Dalbulus maidis is the vector of the diseases. The diseases are very harmfull to corn crops and can cause severe losses. Their importance increased very much in the last years mainly due to the continuous crops, which allow the perpetuation of corn, pathogens and vector over the year. Diseased plants show shortening, redening or yellowing and excessive proliferation of ears, among others symptoms. However, symptoms are variable according to the causal agent, environmental conditions and corn genotype. Correct diagnosis of the diseases has been reached with ELISA (“enzyme-linked immunosorbent assay” and PCR (“polymerase chain reaction”. The use of resistant genotypes of corn is the main strategy of control of the diseases.Os enfezamentos vermelho e pálido são doenças do milho causadas, respectivamente, por um fitoplasma (“maize bushy stunt phytoplasma” e pelo Spiroplasma kunkelii, organismos restritos ao floema das plantas infectadas. Ambas são transmitidas pela cigarrinha Dalbulus maidis. São doenças bastante destrutivas, podendo causar sérios prejuízos aos agricultores. A importância dessas doenças aumentou muito nos últimos anos, devido principalmente aos cultivos “safrinha”, que perpetuam o milho, os patógenos e o vetor no campo durante o ano todo. As plantas doentes exibem redução de crescimento, avermelhamento ou amarelecimento, proliferação excessiva de espigas pequenas e improdutivas, além de outros sintomas. No entanto, esses sintomas dependem do agente causal, condições climáticas e genótipo do milho. A diagnose correta tem sido feita por testes de ELISA (“enzyme-linked immunosorbent assay” e por PCR (“polymerase chain reaction”, devido à complexidade da

O grupo experimental foi composto de 187 animais, divididos em 2 grupos, vacas vacinadas e não vacinadas. As imunizações ocorreram 60 dias antes do parto, 30 dias antes do parto e na primeira semana pós-parto. No dia da secagem e sete dias após o parto foram coletadas amostras para diagnóstico microbiológico dos patógenos causadores de mastite. A ocorrência de casos clínicos foi verificada pelo teste da caneca durante as ordenhas sendo registrados os dados relacionados à intensidade. Amostras foram coletadas mensalmente, a partir do décimo dia de lactação, para avaliação da CCS. A produção de leite foi registrada mensalmente nos primeiros 100 dias de lactação. Verificou-se no grupo vacinado, redução na prevalência de E. coli no pós-parto, na ocorrência de casos clínicos por E.coli nos primeiros 100 dias de lactação bem como na intensidade destes casos clínicos. Não foram observadas diferenças estatísticas significativas na CCS, entretanto vacas vacinadas apresentaram maior produção de leite, comparadas às vacas não vacinadas. A vacinação com E. coli J5 foi eficaz em reduzir a prevalência de infecções intramamárias (IMM ao parto, ocorrência e intensidade dos casos clínicos e aumento na produção de leite nos primeiros 100 dias de lactação.

    Full Text Available FUNDAMENTO: As dermatomicoses causadas por fungos filamentosos não dermatófitos são infecções raras, exceto as onicomicoses, cuja prevalência vem crescendo nos últimos anos. Dentre esses agentes etiológicos destacam-se o Scytalidium dimidiatum e o S. hyalinum, fungos emergentes responsáveis por micoses em unhas e pele. OBJETIVO: Investigar as características epidemiológicas das onicomicoses e micoses de outras localizações causadas pelos fungos do gênero Scytalidium, utilizando-se como parâmetros sexo, idade e localizações das lesões. MÉTODOS: Avaliaram-se 81 amostras com cultura positiva para o gênero em estudo, oriundas de 74 pacientes encaminhados ao Laboratório de Investigação em Dermatologia (ID situado na cidade do Rio de Janeiro (RJ, no período de 1997 a 2006. As amostras foram submetidas a confirmação diagnóstica por exame direto e cultura. RESULTADOS: A prevalência de onicomicoses por Scytalidium spp. foi de 0,87%, entre as idades de 41 e 60 anos (48,64%. Em relação à localização das lesões, os pés foram mais acometidos (91,36%, com predomínio do hálux esquerdo. No exame direto, as estruturas mais encontradas foram hifas hialinas; na cultura, a espécie S. dimidiatum foi a mais frequente. CONCLUSÃO: As onicomicoses por Scytalidium spp. são raras e o S. dimidiatum foi a espécie mais isolada neste laboratório no período em estudo.BACKGROUND: Dermatomycoses caused by non-dermatophyte filamentous fungi are rare infections, except for onychomycosis, whose prevalence has increased over the past few years. Among these etiologic agents, we highlight Scytalidium dimidiatum and S. hyalinum, emergent fungi that cause mycoses that affect the nails and skin. OBJECTIVE: To investigate the characteristics of onychomycosis and other mycoses caused by the fungi Scytalidium spp, using sex, age and site of infection as parameters. METHODS: Eighty-one samples were evaluated showing positive culture for Scytalidium

    Full Text Available Avaliou-se a relação custo-benefício do tratamento da mastite subclínica bovina causada por Staphylococcus aureus. Foram selecionados 270 quartos mamários com mastite subclínica e sadios, divididos em quatro grupos de acordo com o estádio de lactação e o tratamento. O grupo 1 foi formado por animais entre 10 e 60 dias da lactação e tratados contra mastites; o grupo 2 incluiu animais entre 61 dias da lactação e dois meses antes da secagem e tratados contra mastite; o grupo 3 foi formado por animais entre 10 e 60 dias da lactação, não tratados contra mastite; e o grupo 4 foi formado por animais entre 61 dias em lactação e dois meses antes da secagem, não tratados. O tratamento foi realizado pela infusão intramamária de 150mg de gentamicina, uma vez ao dia. A reavaliação foi efetuada após 30 dias. Para os cálculos dos custos com o tratamento, foram considerados uma prevalência de S. aureus de 5% e os gastos com medicamento, descarte do leite, antibiograma e mão-de-obra. Observou-se redução de 2% e 14% das receitas nos grupos 1 e 2, respectivamente, quando comparada com as receitas obtidas antes do tratamento, demonstrando ser economicamente inviável o tratamento da mastite subclínica bovina causada por S. aureus, durante a lactação.Economic evaluation of the treatment bovine subclinical mastitis caused by S. aureus was evaluated. Two hundred and seventy udder quarters with or without subclinical mastitis were distributed into four groups, in conformity to lactational stage and treatments. Group 1 included animals treated between 10 and 60 days of lactation; group 2 included animals treated from 61 days of lactation to two months before drying; group 3 included animals no treated between 10 and 60 days of lactation; group 4 included animals no treated from 61 days of lactation to two months before drying. Treatment with gentamicin (150mg was accomplished by intramammary doses, once a day, after performing sensitivity

    Full Text Available Cerebral ischemic processes associated with infective endocarditis caused by Streptococcus bovis are rare; only 2 cases having been reported. Here we report a case of a 50-year-old man with S. bovis endocarditis who presented signs of frontal, parietal and occipital lobe cerebral ischemia. This is the first case reported in which the presence of hemianopsia preceded the endocarditis diagnosis. Initially, the clinical manifestations suggested a systemic vasculitis. Later, vegetating lesions were identified in the aortic valve and S. bovis grew in blood cultures. Antibiotic use and aortic valve replacement eliminated the infection and ceased thromboembolic events. A videocolonoscopy examination revealed no mucosal lesions as a portal of entry in this case, although such lesions have been encountered in up to 70% of reported cases of S. bovis endocarditis.A associação de isquemia cerebral e endocardite por Streptococcus bovis é um evento raro, tendo sido publicados apenas 2 casos anteriormente. Nós relatamos o caso de um homem de 50 anos com endocardite por S. bovis que apresentou sinais isquêmicos nos lobos frontal, parietal e occipital. Este é o primeiro caso em que a hemianopsia precedeu o diagnóstico de endocardite. Inicialmente, o quadro foi confundido com vasculite. Posteriormente, foi confirmada a presença de vegetações na válvula aórtica e a hemocultura identificou S. bovis. Os eventos tromboembólicos foram controlados com o uso de antibióticos e a troca da válvula aórtica. Estudo videocolonoscópico não identificou nenhuma lesão, apesar de lesões colônicas serem descritas em até 70% dos casos de indivíduos com endocardite por S. bovis.

    Full Text Available A luxação do bulbo ocular ocorre quando há seu deslocamento anterior, de tal forma que as pálpebras se fecham espasmodicamente por detrás dele. Diversas causas não traumáticas são relatadas, sendo que, quando provocado por traumas contusos, com grande envolvimento do nervo óptico e da musculatura extrínseca ocular, o prognóstico em geral é desfavorável. Apresentamos um dramático caso de luxação do bulbo ocular em criança após acidente doméstico, destacando seu mecanismo fisiopatológico e apreciando as condutas.The eyeball luxation is a dramatic phenomenon in which there is a forward displacement of the eyeball so that the eyelids spasmodically close behind it. There are many risk factors, non-related to trauma, but orbital contusions with optic nerve and extraocular muscles involvement carry the worst prognosis. The present paper reports a dramatic domestic case of globe luxation in childhood, its pathophysiology mechanisms and management.

    Full Text Available As lesões de aspecto ulcerado na mucosa bucal são um achado comum na clínica odontológica e geralmente são ocasionados por trauma mecânico devido a próteses mal adaptadas, aparelhos ortodônticos e dentes com coroas ou restaurações fraturadas. Contudo, os indivíduos nos quais a lesão persiste por mais de três semanas deverão ser submetidos à biopsia ou outros exames para excluir algumas lesões de caráter neoplásico ou outras condições, tais como as infecções crônicas e as doenças de caráter imunológico. Durante o tratamento ortodôntico, a dor e o desconforto da mucosa bucal podem acontecer como resultado do traumatismo mecânico dos aparelhos, ocasionado pela fricção aumentada entre o tecido da mucosa e a superfície dos braquetes. Atualmente, o ortodontista possui poucos recursos para prevenir ou aliviar esta irritação na mucosa. O objetivo deste artigo é orientar o ortodontista para o manejo mais adequado destas lesões visando o seu diagnóstico correto, o alívio dos sintomas que estas costumam provocar e o tratamento mais adequado para cada tipo de caso.Mouth ulcers are one of the most commom complaints in the dental clinic. They are, in general, caused for mechanic traumatism induced by non-fitted dentures, orthodontic appliances and fracturated crowns and fillings. Nevertheless, those lesions that have persisted for more than three weeks should be submitted to biopsy or other exams to exclude neoplasic, infectious or immunologic lesions. During the orthodontic treatment, pain and soreness of the oral mucosa can occur as the result of mechanic traumatism caused by increased friction between soft tissues and brackets. Nowadays, the professional owns few resources to prevention or relieve this irritation on the oral mucosa. The aim of this article is to guide the orthodontist to realize the correct diagnoses of the mouth ulcers, the relieve the symptoms and the exact treatment for each type of case.

    Full Text Available Durante as atividades de extensão rural, desenvolvidas pelo Núcleo de Pesquisa em Mastites - NUPEMAS, do Departamento de Higiene Veterinária e Saúde Pública, da Faculdade de Medicina Veterinária e Zootecnia da Universidade Estadual Paulista - Botucatu - São Paulo - Brasil, no ano de 2002, foi isolado de uma propriedade leiteira do interior do estado, o fungo Trichosporon beigelii, em quatro animais com mastite clínica, e em três com mastite subclínica. Este fungo é de grande importância, pois é responsável pelo desenvolvimento de quadros de micose superficial, conhecidos como piedra branca. No Brasil, até o presente momento, não há relato de isolamento de Trichosporon beigelii, como agente causador de mastites. Este fato confirma a importância do exame microbiológico para o monitoramento das mastites, pois permite a identificação de patógenos tanto nas infecções intramamárias subclínicas como clínicas, evitando-se o tratamento com antimicrobianos, que nestes casos em particular, além de não exercer seu efeito terapêutico, pode predispor a infecções mistas por outros agentes fúngicos, na medida em que os antimicrobianos fornecem substrato para o desenvolvimento e manutenção destes.

    Full Text Available A intoxicação medicamentosa é um problema de grande relevância para a saúde pública. No Brasil, os medicamentos são os principais agentes responsáveis por intoxicações humanas. Este artigo objetivou descrever o perfil e a evolução das intoxicações no município de Feira de Santana, Bahia, nos anos 2007 a 2010, e analisar a morbimortalidade causada por medicamentos. Neste estudo transversal, com caráter descritivo, foram analisados 631 casos registrados no SINAN. As variáveis utilizadas foram: sexo; faixa etária; raça; escolaridade; ocupação; evolução do caso notificado; zona de ocorrência da intoxicação; circunstância determinante para a ocorrência da intoxicação; tipo de exposição; frequência deste agravo; e tipo de unidade notificadora. Constatou-se que a intoxicação por medicamentos representou 33% das intoxicações, seguida de “raticidas” (18%, sendo a “tentativa de suicídio”, circunstância responsável, em 2010, por 81% das notificações. O sexo ‘feminino’ apresentou o maior número de casos registrados, bem como as crianças de 1 a 4 anos e os adultos jovens. A letalidade observada em Feira de Santana foi muito maior do que a média regional e nacional, excetuando-se o ano de 2009. A Vigilância em Saúde deve priorizar ações educativas, preventivas e intersetoriais, que assegurem o uso correto de medicamentos e melhorem seu impacto na saúde, bem como investir na sensibilização continuada dos profissionais da Atenção Básica para melhorar a notificação deste importante agravo.

A comparação das cultivares pelas porcentagens de perda de massa por espigueta e de espiguetas vazias não apresentou efeitos diferenciados entre tratamentos, nem interação "tratamentos x cultivares" significativa. A avaliação da atividade alimentar, pela presença de bainhas de estilete, mostrou que o percevejo O. ypsilongriseus foi mais ativo que O. poecilus. Esses afetaram de modo diferente o vigor das cultivares, entretanto, não influenciaram o teor de amilose. Os percevejos também reduziram o rendimento total de arroz beneficiado e aumentaram o número de grãos inteiros manchados, apesar de não terem alterado o número total de grãos inteiros.

    PALAVRAS-CHAVE: Inseto; percevejo das panículas; bainha de estilete.

    Full Text Available Embora sejam as forrageiras mais importantes para a pecuária de corte (bovinocultura de corte no Brasil, em certas épocas ou condições, Brachiaria spp. podem ser tóxicas e causar surtos de fotossensibilização hepatógena que determinam significativas perdas econômicas. Animais que se alimentam em pastos de Brachiaria spp. comumente apresentam macrófagos espumosos isolados ou agrupados, além de cristais no interior de ductos biliares. Saponinas esteroidais têm sido identificadas nestes cristais e são responsabilizadas por lesar o fígado levando ao acúmulo de filoeritrina. Por vezes, imagens negativas desses cristais podem estar presentes no citoplasma de macrófagos espumosos. A patogênese de formação e o tipo de material armazenado nas células espumosas ainda são desconhecidos. A técnica de lectino-histoquímica visa auxiliar na detecção desses macrófagos e, consequentemente, no diagnóstico, além de identificar quais os resíduos de açúcares específicos que estão presentes no citoplasma das células espumosas. Assim, este trabalho teve por objetivo identificar quais lectinas são mais indicadas na detecção de saponinas esteroidais no fígado e rim de ovinos com fotossensibilização causada por Brachiaria decumbens. Fragmentos de fígado e rim de quinze ovinos, de ambos os sexos e idade variável, oriundos de Conceição do Mato Dentro, Minas Gerais, e um ovino mantido em pastagem livre de Brachiaria spp. foram avaliados pela técnica de lectino-histoquímica. Quatorze lectinas foram utilizadas (Con-A, DBA, SBA, PNA, SJA, RCA-I, UEA-I, WGA, SWGA, GSL, PSA, PHA-L, PHA-E e LCA. Verificou-se que, no fígado de ovinos com fotossensibilização provocada pela ingestão de Brachiaria decumbens, a lectina PNA apresentou especificidade e acentuada reatividade aos macrófagos espumosos, bem como especificidade e leve reatividade aos hepatócitos; a lectina WGA teve especificidade e moderada reatividade aos macr

    Full Text Available Neste trabalho, são apresentados os principais problemas decorrentes das infecções intramamárias (mastites causadas por Staphylococcus aureus e as conseqüências para a saúde humana da veiculação de suas toxinas através do leite. o S. aureus destaca-se como um dos microorganismos mais importantes que podem ser transmitidos através dos alimentos. Assim, discute-se a possibilidade de veiculação de gastroenterite estafilocócica, não somente através do consumo de leite cru contaminado, mas também de leite tratado termicamente ou de derivados lácteos contendo enterotoxinas termoestáveis. São apresentados alguns aspectos relacionados ao potencial toxigênico das cepas de S. aureus, bem como as principais características das enterotoxinas estafilocócicas. Considerando que o S. aureus é um dos agentes de mastite mais freqüentemente observados, apresentam-se as principais medidas de controle de infecções estafilocócicas em rebanhos leiteiros, com vistas à prevenção da ocorrência de toxinas no leite de consumo.This article presents the main problems derived from the mammary infections (mastitis caused by Staphylococcus aureus, and the consequences of the presence of its toxins in milk for human health. S. aureus is one of the most important microorganisms that can be transmitted through the food products. Hence, the possibility of transmission of stafilococal gastroenteritis by consumption of raw milk and heat-treated milk, containing heat-resistant enterotoxins, is discussed. Some aspects regarding the toxigenic potential of S. aureus strains and the main characteristics of stafilococal entorotoxins are presented. Taking into account that S. aureus is also one of the most prevalent agents of mastitis, considerations are made on the methods for the controlling of stafilococal infections in dairy cattle, in order to prevent the occurrence of toxins in milk and milk products.

    Full Text Available A incorporação de matéria orgânica ao solo tem se mostrado eficiente para o controle de alguns fitopatógenos habitantes do solo. O efeito dessa prática agrícola, principalmente sobre patógenos formadores de escleródios, como Sclerotium rolfsii, ainda não é completamente conhecido. O experimento, em dois anos de cultivo, foi conduzido no campo experimental da Universidade Tecnológica Federal do Paraná (UTFPR, em parcelas de um metro quadrado, contendo solo infestado com 100 g por parcela do substrato (arroz em casca contendo o patógeno. Os tratamentos foram chorume de suínos, cama de aviário, repolho triturado e testemunha, apenas patógeno, com quatro repetições. A semeadura de 80 sementes de feijão por parcela foi efetuada após uma semana da aplicação dos respectivos tratamentos. A intensidade da doença foi avaliada pela emergência, tombamento, incidência e severidade da doença. Os fatores como atividade microbiana, níveis de fertilidade do solo, número e sobrevivência de escleródios e massa das plantas fresca foram avaliados no fim do cultivo. O composto orgânico, cama de aviário, apresentou uma maior redução da incidência e a severidade da doença e, consequentemente, o tombamento de plântulas. Porém, apesar de reduzir a intensidade da doença, não houve aumento da emergência nos dois primeiros cultivos. Esse efeito benéfico da cama-de-aviário (CA pode estar associado ao aumento da matéria orgânica do solo e, consequentemente, da atividade microbiana, principal responsável pela redução da patogenicidade do fungo. Como consequência ao impacto provocado pela incorporação de CA ao solo, houve aumento da massa fresca da planta e redução do número de escleródios. Assim, com base nesses resultados, pode-se concluir que a CA apresenta efeito supressivo sobre as doenças causadas por S. rolfsii.AbstractOrganic matter incorporation into the soil has proved effective for the control of some soil

    Full Text Available Cerebral aspergillosis is a rare cause of brain expansive lesion in AIDS patients. We report the first culture-proven case of brain abscess due to Aspergillus fumigatus in a Brazilian AIDS patient. The patient, a 26 year-old male with human immunodeficiency virus (HIV infection and history of pulmonary tuberculosis and cerebral toxoplasmosis, had fever, cough, dyspnea, and two episodes of seizures. The brain computerized tomography (CT showed a bi-parietal and parasagittal hypodense lesion with peripheral enhancement, and significant mass effect. There was started anti-Toxoplasma treatment. Three weeks later, the patient presented mental confusion, and a new brain CT evidenced increase in the lesion. He underwent brain biopsy, draining 10 mL of purulent material. The direct mycological examination revealed septated and hyaline hyphae. There was started amphotericin B deoxycholate. The culture of the material demonstrated presence of the Aspergillus fumigatus. The following two months, the patient was submitted to three surgeries, with insertion of drainage catheter and administration of amphotericin B intralesional. Three months after hospital admission, his neurological condition suffered discrete changes. However, he died due to intrahospital pneumonia. Brain abscess caused by Aspergillus fumigatus must be considered in the differential diagnosis of the brain expansive lesions in AIDS patients in Brazil.La aspergilosis cerebral es una causa rara de lesión expansiva cerebral en pacientes con SIDA.

    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 A anomalia do cultivar de videira Niagara Rosada, caracterizada por sintomas de clorose nas folhas, chocolate das bagas e cachos malformados, não é de natureza virótica, de acordo com resultados de testes de transmissão e de perpetuação. Essa anomalia, presente em áreas definidas de alguns vinhedos de Indaiatuba e Jundiaí (SP, está associada à deficiência nutricional de boro. O teor médio de boro em amostras de plantas afetadas de 'Niagara Rosada' (18 ppm no limbo e 7 ppm nos frutos foi menor do que nas de plantas normais (24 ppm no limbo e 10 ppm nos frutos das mesmas plantaçoes; um material coletado de um vinhedo bastante afetado mostrou 13 e 1 ppm respectivamente no limbo e nos frutos de plantas deficientes contra 20 e 6 ppm nos de plantas sem sintomas. Amostras de três vinhedos vizinhos sem essa anomalia apresentaram um teor médio de 35 ppm no limbo. As do porta-enxerto 'Traviú' com clorose e sem clorose mostraram 16 ppm e 43 ppm de boro respectivamente. A aplicação de bórax, nas doses de 5, 10 e 20g por planta, 1ogo após a poda de inverno, ou pulverização de ácido bórico nas concentraçoes de 0,3% e 0,6% sobre a folhagem, durante o início do florescimento e durante a fase de uva chumbinho, permitiram controlar a anomalia nas condições de campo.

    Full Text Available Actualmente, Streptococcus pneumoniae resistente a penicilina es un patógeno común en infecciones pediátricas, lo cual plantea dificultades en el tratamiento. La rifampicina y el cloranfenicol se han recomendado como antibióticos útiles y como alternativas en estos casos, pues son menos costosos y más accesibles a las comunidades de recursos limitados. Su uso, sin embargo, puede estar limitado por los niveles de resistencia encontrados en diferentes poblaciones. El objetivo del presente estudio fue determinar la concentración inhibitoria mínima (CIM y la concentración bactericida mínima (CBM a la rifampicina y al cloranfenicol en aislamientos de S. pneumoniae pertenecientes a un grupo recolectado entre 1994 a 1996 de niños menores de 5 años con infección sistémica y meningitis. Se estudiaron 107 aislamientos, 60 de ellos resistentes a penicilina y 47 sensibles, 53 de los cuales fueron aislamientos de LCR. La CIM y la CBM se realizaron de acuerdo con las recomendaciones de la NCCLS; se utilizó S. pneumoniae ATCC 49619 como control. Se consideraron como sensibles al cloranfenicol los aislamientos con CIM=4 ?g/ml y resistentes, con CIM=8 ?g/ml; sensibles a rifampicina con CIM=1 ?g/ml y resistentes con CIM=4 ?g/ml. La CBM se determinó con la menor concentración del antibiótico que inhibió el crecimiento del 99,9% del inóculo. Se encontró resistencia al cloranfenicol en 20,5% de los 107 aislamientos estudiados. En el grupo resistente a la penicilina, 28% fue resistente al cloranfenicol y 11% en el grupo sensible a la penicilina. La CBM para el cloranfenicol fue >4 ?g/ml en 28% de los aislamientos sensibles a la penicilina y en 60% de los resistentes. No se encontraron aislamientos resistentes a la rifampicina; sin embargo, 2 aislamientos mostraron CBM>1 ?g/ml y una CBM=16 ?g/ml. Los aislamientos de LCR presentaron la CIM y la CBM más altas que el grupo total de aislamientos. Los datos sugieren que en Colombia el cloranfenicol no

    Full Text Available Doenças difusas do parênquima pulmonar pertencem a um grupo de doenças de evolução geralmente subaguda ou crônica, mas que podem determinar insuficiência respiratória aguda. Paciente masculino, 37 anos, em terapia para linfoma não Hodgkin, admitido com tosse seca, febre, dispneia e insuficiência respiratória aguda hipoxêmica. Iniciadas ventilação mecânica e antibioticoterapia, porém houve evolução desfavorável. Tomografia computadorizada de tórax mostrava opacidades pulmonares em "vidro fosco" bilaterais. Devido ao paciente ter feito uso de três drogas relacionadas à pneumonia em organização (ciclofosfamida, doxorrubicina e rituximabe e quadros clínico e radiológico serem sugestivos, iniciou-se pulsoterapia com metilprednisolona com boa resposta. Pneumonia em organização pode ser idiopática ou associada a colagenoses, drogas e neoplasias, e geralmente responde bem a corticoterapia. O diagnóstico é anatomopatológico, mas condições clínicas do paciente não permitiam a realização de biópsia pulmonar. Pneumonia em organização deve ser diagnóstico diferencial em pacientes com aparente pneumonia de evolução desfavorável ao tratamento antimicrobiano.

    Full Text Available Las especies de hongos de suelo asociadas a Cephalosporium maydis como agente causal de la marchitez tardía del maíz en la Península Ibérica se identificaron muestreando 19 campos con síntomas de marchitez en las principales zonas de cultivo entre 2011 y 2012. En el 47% de los campos no se identificó C. maydis, pero sí Fusarium graminearum, F. verticillioides, F. equiseti, F. proliferatum, Macrophomina phaseolina, Rhizoctonia solani y Trichoderma harzianum infectando las plantas de maíz. En los campos restantes, junto a C. maydis se identificaron otros hongos de suelo en porcentajes apreciables: F. verticillioides (19%, F. proliferatum (19%, F.equiseti (9%, F. oxysporum (9% y Pythium oligandrum (9%. El crecimiento vascular de C. maydis y de otras especies fúngicas en plantas de maíz se confirmó analizando plantas con marchitez procedentes de tres campos diferentes. Tanto C. maydis como F. graminearum, F. equiseti, F. proliferatum y T. harzianum se aislaron de la inserción entre la raíz y tallo y a 10 cm de altura en el tallo de las plantas. El efecto de la infección por C. maydis sobre la producción de las plantas de maíz se cuantificó en macetas y condiciones seminaturales en el 2011. En plantas inoculadas se obtuvo una reducción del peso de las mazorcas del 54%, además de pesos de raíz y de parte aérea (tallo y hojas significativamente menores en comparación con el control no inoculado, lo que sugiere el gran impacto económico que puede tener la marchitez tardía en condiciones naturales. Asimismo este trabajo pone de manifiesto el grado de complejidad de la etiología de la marchitez tardía, que debería ser estudiado mediante la confirmación de la patogenicidad de los hongos de suelo identificados en maíz, con el fin de determinar el papel que puede jugar cada una de estas especies en el desarrollo de la enfermedad y/o severidad de los síntomas.

    Full Text Available La encefalitis herpética es una enfermedad grave asociada al virus herpes simple 1 ó 2, con una alta letalidad, incidencia de complicaciones y secuelas neurológicas permanentes. Aparece en forma endémica y en pacientes inmunocompetentes. Puede manifestarse como un cuadro clásico de encefalitis infecciosa con fiebre, cefalea y alteración en el nivel de conciencia. Debido al compromiso del lóbulo temporal las manifestaciones clínicas pueden incluir también alucinaciones, afasia y cambios de personalidad. Las secuelas en los pacientes tratados son significativas. Objetivo: mostrar la importancia de la utilización del diagnóstico molecular temprano en pacientes con sospecha de encefalitis herpética. Métodos: el diagnóstico de la encefalitis herpética ha cambiado en los últimos años gracias al advenimiento de la reacción en cadena de la polimerasa en tiempo real en líquido cefalorraquídeo para Herpes virus simple, una estrategia rápida y de alta sensibilidad y especificidad, que en nuestro medio ha permitido reemplazar los diagnósticos presuntivos realizados por tomografía axial computarizada o electroencefalograma o los bajos rendimientos del aislamiento viral en el líquido cefaloraquídeo. Resultados: se describe el caso clínico de un paciente con encefalitis herpética asistido en nuestro hospital, con diagnóstico confirmado por reacción en cadena de la polimerasa en tiempo real, presentando estudios imaginológicos y neuropsicológicos compatibles con el diagnóstico. Conclusiones: los resultados de laboratorio y el diagnóstico temprano son críticos para el tratamiento precoz y la evolución del paciente.

    Full Text Available This research was aimed to compare the postharvest
    performance of the disease caused by the fungus Botrytis cinerea Pers., as well as the Petal Blackening in roses grown in greenhouses cover with plastic of different transmittance to the ultraviolet light. Furthermore, the effect of a climatic screen over the two problems was evaluated. The trial was
    done in the "Centro de Investigaciones y Asesorías Agroindustriales" located in Chía, Cundinamarca, under greenhouses with the same features as the ones used in commercial rose cultivation, with the varieties "Eterna" and "Madame Delbard" and its clones 13 and 15. The effect of the plastic over the disease made a clear difference, showing a lower development of the diseas e in the greenhouse covered with photoselective plastic, as compared with the commercially used plastic. A lower effect of this cover was
    found related to the Petal Blackening, where the results were rather similar between the two plastic types. The climatic screen did not show difference over any of the two problems, under these conditions. The effect of the varieties was not very clear related to the disease, but it in fact was in relation

    pacientes humanos com lesões cutâneas de leishmaniose na Província de Santiago del Estero, no Norte da Argentina. Os procedimentos de diagnóstico foram: biópsias de lesões para utilização em esfregaços e inoculação em hamster; aspiração (com agulha de úlceras, para cultura "in vitro". As técnicas imunodiagnósticas empregadas foram a IFAT-IgG e o teste intradérmico de Montenegro. Oito cepas de parasitas foram isoladas, sendo estas obtidas de pacientes com lesões ativas. Todas as cepas foram inicialmente caracterizadas biologicamente por seu comportamento na infecção experimental do hamster, mensuração dos amastigotas e promastigotas e crescimento "in vitro". As mesmas oito cepas foram logo identificadas e caracterizadas a nível de espécie, devido a sua reatividade frente a um painel de anticorpos monoclonais subgênero e espécie-específicos. Isso foi realizado utilizando o teste de Imunofluorescência Indireta (IFAT/MAbs e de um procedimento de Dot-ELISA. Nós concluímos a partir da análise de serodema dos isolados argentinos que: MHOM/AR/92/SE-1; SE-2; SE-4; SE-8; SE-8-I; SE-30; SE-34 e SE-36 são Leishmania (Viannia braziliensis. Entretanto, três dos isolados de Leishmania (SE-1; SE-2 e SE-30 não foram reconhecidos quando testados com um anticorpo monoclonal de reconhecida alta espécie-especificidade (clone B-18, marcador consagrado de Leishmania (Viannia braziliensis, revelando a existência de dois tipos de serodemas entre as cepas estudadas.

Descrevemos um caso de HZ oftálmico numa menina de 29 meses, previamente saudável. Apresentava febre e erupção cutânea vesicular dolorosa no território oftálmico do nervo trigémio. Sem história de varicela ou vacinação anti-varicela prévias. Teve contacto intrafamiliar com varicela aos dois meses de idade. A pesquisa do vírus nas vesículas por polimerase chain reaction foi positiva. Os títulos de IgG e IgM anti-vírus varicela-zoster foram inicialmente negativos, tendo ocorrido seroconversão oito semanas depois. Medicada com aciclovir endovenoso, recuperou sem sequelas. O HZ pode ocorrer em crianças previamente saudáveis, sem evidência de varicela anterior e com serologia para VVZ negativa. Tal pode ser explicado pela imaturidade do sistema imunológico, assim como pela transferência transplacentária de anticorpos maternos, aquando da infeção primária precoce.

    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.

    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

Moreover, PCR has enabled us to use residue volumes of urine samples collected by non invasive, non sterile methods, what is technically adequate as GBS is not part of the normal urine flora, thus avoiding invasive procedures such as suprapubic bladder punction or transurethral catheterization. At the same time, the use of urine instead of blood samples could help preventing newborns blood spoliation.O estreptococo do grupo B (GBS constitui a causa mais freqüente de sepse neonatal precoce. O teste de referência continua sendo o isolamento em cultura, apesar de apresentar problemas de sensibilidade. O objetivo do presente estudo foi validar uma técnica de dupla amplificação e determinar a possibilidade do uso de amostras residuais de urina colhidas por método não invasivo, não estéril, para a confirmação da sepse por GBS em recém-nascidos. As amostras foram amplificadas com primers do principal gene de superfície do GBS. A insuficiência de volume de material biológico para a realização de exames para suporte de vida, além de outros necessários à identificação do agente etiológico de infecções é muito freqüente em recém-nascidos. Mesmo assim, decidimos definir critérios bastante rigorosos para a inclusão de pacientes na casuística: os recém-nascidos deveriam apresentar sinais e sintomas compatíveis com infecção pelo GBS; deveriam ter tido ao menos uma amostra enviada para cultura, podendo ser sangue, urina ou líquor; disponibilidade de volumes residuais dessas amostras, ou de outras colhidas no dia da hospitalização, antes da introdução da antibioticoterapia, de forma a possibilitar a análise por PCR, e evolução favorável com a antibioticoterapia empírica. Em apenas um dos quatro recém-nascidos a infecção foi confirmada por cultura, enquanto nos outros três casos a infecção foi considerada presuntiva (pacientes preencheram os critérios de inclusão, mas o GBS não foi isolado.

Em outro experimento, 4 ovinos foram também colocados, presos por cordas, na mesma área. Outros 4 permaneceram como controles em uma pastagem vizinha, mas sem F. humboldtiana. Lesões de pele, características de fotossensibilização foram observadas após 11-25 dias de consumo de F. humboldtiana. As atividades séricas de AST e GGT, e os níveis de bilirrubina sérica permaneceram dentro dos valores normais. No final do período de permanência em pastagens de F. humboldtiana, 2 ovinos foram abatidos e 2 foram retirados da pastagem. Os que foram abatidos não apresentaram lesões macroscópicas nem histológicas do fígado; os outros dois se recuperaram das lesões da pele 17 e 20 dias após o fim do pastejo.

    Full Text Available Dois experimentos foram conduzidos em pomares de goiabeira 'Paluma', nos municípios de Monte Alto e Vista Alegre do Alto-SP. No primeiro experimento, avaliou-se o efeito de formulações de fungicidas cúpricos, aplicados isoladamente e em mistura com mancozeb, quanto ao efeito fitotóxico em botões florais e em frutos de goiabeira, em três estádios de desenvolvimento. No segundo experimento, foram avaliados os mesmos fungicidas usados no primeiro experimento, sendo, porém, acrescido do tratamento constituído por tebuconazole, cujo alvo foi sua eficiência no controle da ferrugem. No primeiro experimento, verificou-se que nenhum dos fungicidas testados causou abortamento de flores ou outros tipos de sintomas de fitotoxicidade em frutos de tamanho inferior a 15 mm de diâmetro. Contrariamente, estes fungicidas, quando aplicados isoladamente, em frutos entre 25 a 35 mm de diâmetro, causaram sintomas severos de fitotoxicidade. Em frutos de tamanho superior a 40 mm de diâmetro, estes fungicidas causaram sintomas de fitotoxicidade de níveis leves a moderados. A combinação de fungicidas cúpricos com mancozeb causou sintomas de fitotoxicidade em níveis leves, enquanto com mancozeb isoladamente não foram verificados sintomas de fitotoxicidade. No segundo experimento, verificou-se que os fungicidas cúpricos, aplicados isoladamente, foram eficientes no controle da ferrugem da goiabeira, apresentando eficiência comparável ao tratamento-padrão representado por tebuconazole. Esta eficiência foi também observada mediante o emprego da combinação mancozeb e óxido cuproso ou hidróxido de cobre.Two experiments were carried out in guava orchards cv. 'Paluma' at Monte Alto and Vista Alegre do Alto/SP. In Experiment 1 it was used copper fungicides applied alone and in combination with mancozeb to evaluate the effect of phytotoxicity on floral buds and guava fruits in three developmental stages. In Experiment 2 it was used the same fungicides

    Full Text Available FUNDAMENTOS: Nos últimos anos, existe um aumento progressivo do contato de moradores urbanos com ambientes selvagens devido a atividades de lazer. Com isso, algumas dermatites pouco conhecidas podem ser observadas nas clínicas privadas e ambulatórios dermatológicos, especialmente nos inícios de semana e finais de férias. OBJETIVOS: Obter e fornecer informações para dermatologistas sobre o problema. PACIENTES E MÉTODOS: O autor observou, em adultos e crianças, dermatites agudas associadas a plantas ou animais em Ubatuba, cidade litorânea de São Paulo, por dois meses (junho/julho de 2006 e na Faculdade de Medicina de Botucatu, também por dois meses (junho/julho de 2007. RESULTADOS: Foram observados 25 pacientes na área rural e 43 na área litorânea nas condições estabelecidas. Em áreas rurais, foram mais observadas fitofotodermatites e picadas de insetos, enquanto em áreas litorâneas traumas por ouriços-do-mar e fitofotodermatites predominaram; entretanto, em ambas as áreas ocorreram outros acidentes de difícil identificação na prática diária. CONCLUSÕES: Devemos estar atentos ao fato de o paciente procurar o dermatologista somente após as fases agudas dos acidentes. Informações sobre as enfermidades mais comuns e suas características podem ser muito úteis para a prática nos consultórios. O autor sugere uma tabela algorítmica para auxílio diagnóstico.BACKGROUND: In recent years, there has been increasing contact between human beings that live in urban regions and the wild environment due to a series of activities.

Esta bateria reproduziu sintomas semelhantes aos da doença quando inoculada em plantas de milho em casa de vegetação. Estudos anteriores realizados por outros autores demonstraram que o controle desta doença em condições de campo foi obtido pelo uso de fungicidas, principalmente o Mancozeb, nas fases iniciais de seu desenvolvimento. O objetivo deste estudo foi avaliar a freqüência de isolamento da bactéria P. ananatis a partir de plantas infectadas coletadas na região de Londrina, Estado do Paraná, e reproduzir sintomas da doença através de inoculações artificiais em plantas de milho em casa de vegetação. Utilizando os produtos químicos testados anteriormente por outros autores para o controle desta doença a campo, foi também objetivo deste trabalho avaliar o potencial destes produtos na inibição da bactéria tanto em condições de laboratório como em condições de infecção natural. Os resultados mostraram que P. ananatis foi isolada em 40% das lesões jovens coletadas a campo e quando inoculada em casa de vegetação sob condições controladas reproduziu sintomas semelhantes aos observados a campo. Entre os produtos químicos testados, o fungicida Mancozeb mostrou-se eficiente no controle da doença a campo, em concordância com os relatos anteriores. Este produto inibiu completamente o crescimento da bactéria em laboratório, explicando os resultados obtidos a campo. Os demais produtos não foram eficientes no controle a campo e eles também não inibiram a bactéria em laboratório.

    2016-06-01

    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.

    Full Text Available The Peutz-Jeghers syndrome is a hereditary disease that requires frequent endoscopic and surgical intervention, leading to secondary complications such as short bowel syndrome. CASE REPORT: This paper reports on a 15-year-old male patient with a family history of the disease, who underwent surgery for treatment of an intestinal occlusion due to a small intestine intussusception. DISCUSSION: An intra-operative fiberscopic procedure was included for the detection and treatment of numerous polyps distributed along the small intestine. Enterotomy was performed to treat only the larger polyps, therefore limiting the intestinal resection to smaller segments. The postoperative follow-up was uneventful. CONCLUSION: We point out the importance of conservative treatment for patients with this syndrome, especially those who will undergo repeated surgical interventions because of clinical manifestation while they are still young.A síndrome de Peutz-Jeghers é uma doença de caráter hereditário que freqüentemente requer intervenções endoscópicas e cirúrgicas repetidas, levando a complicações secundárias como, por exemplo, a síndrome do intestino curto. RELATO DE CASO: Relatamos neste artigo o caso de paciente de 15 anos, masculino, com história familiar para a doença, que foi submetido ao procedimento cirúrgico para tratar oclusão devido a intussucepção de intestino delgado. DISCUSSÃO: Associou-se método fibroscópico intra-operatório com a finalidade de detecção e ressecção de numerosos pólipos distribuídos em todo o intestino delgado. Realizaram-se enterotomias para a retirada dos pólipos maiores, restringindo-se, portanto, a ressecção intestinal a segmentos menores. A evolução clínica foi boa. CONCLUSÃO: Ressalta-se a importância do manejo de forma conservadora dos pacientes portadores desta síndrome, principalmente naqueles cujas manifestações clínicas de importância cirúrgica aparecem precocemente.

    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.

    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).

    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.

    Full Text Available O Herpes simplex (HSV é um DNA vírus que provoca afecções perianais, sendo considerada a causa mais comum das úlceras na região. 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. Os testes imunohistoquímicos sugerem o HSV. A opção terapêutica inicial deve ser o tratamento medicamentoso.

    The spore viability of Alternaria dauci (Kühn Groves & Skolko in carrot (Daucus carota L. debris which were kept at different levels of temperature and relative humidity, without light, was studied. The temperature levels tested were 8, 16, 24 and 32°C, and the relative humidity levels 3, 18, 51, 73 and 100%. The treatments were different combinations of these levels. Humidity was the more important factor in preserving the fungus spore ability to germinate and its infectivity. Under conditions of high relative humidity and temperatures of 24 and 32°C, the spores rapidly lost their viability. This did not happen when the relative humidity was equal to, or below, 51%. The survival of fungus mycelium on carrot petioles was studied in non-treated organic soil, at different humidity levels, at three different depths, during a period of 120 days. Soil humidity was the factor of major significance in the persistence of the mycelium, followed by depths and time factors. In petioles kept at depths of 10 and 20 cm in humid soil, the survival was greatly reduced, while survival was markedly higher in those kept at the surface of dry soil. The effect of humidity on the viability of mycelium was studied also under soiless condition. Petioles were maintained in relative humidity controlled chamber, at 24°C. In saturated atmosphere (100% humidity, the mycelium viability was lost in less than 20 days. It was concluded that both, the conidial and mycelial form of Alternaria dauci are quite sensitive to high humidity levels.

    Estudou-se a sobrevivência das formas conidial e miceliana de Alternaria dauci, respectivamente, sobre folhas necrosadas e pecíolos de cenoura, sob diferentes condições mesológicas. Os esporos do fungo sobre conidióforos em folhas necrosadas de cenoura foram mantidos por 120 dias sob condi

    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.

    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.

    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.

    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.

    Full Text Available El principal factor que interviene en el origen y prevención de las enfermedades trasmitidas por los alimentos es la higiene alimentaria. Dichas enfermedades son causadas por la ingestión de alimentos o agua contaminados con microorganismos patógenos ocasionando una infección o por la ingestión de alimentos contaminados con toxinas. Los principales agentes involucrados son Escherichia Coli, Campylobacter, Salmonella, Shigella, Listeria Monocytogenes, Norovirus, virus Hepatitis A, Astrovirus, Rotavirus, y Virus Coxsackie. Toxinas producidas por hongos o por microflora marina y los contaminantes orgánicos persistentes pueden también causar serios problemas de salud. La inocuidad alimentaría ha tomado relevancia debido a una mayor exigencia por consumidores cada día más informados y por las demandas del comercio exterior. Medidas que aseguren una adecuada higiene alimentaría nos permitirá prevenir enfermedades, principalmente digestivas, causadas por variados agentes en los alimentos. Esto se logra por la implementación de las medidas propuestas por la Comisión Internacional conocida como Codex Alimentarius.

    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. Another hypothesis is that reactivation of a neurotropic herpes virus can reactivate another neurotropic virus if both types are present in the same ganglion....... If co-infection with HSV/VZV is suspected the treatment regimen for herpes zoster will sufficiently treat a possible HSV infection also....

    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.

    Neonatal herpes simplex virus infections are rare, but are associated with significant morbidity and mortality. Most newborns acquire herpes simplex virus infection in the peripartum period. For peripartum transmission to occur, women must be shedding the virus in their genital tracts symptomatically or asymptomatically around the time of delivery. There are evidence-based interventions in pregnancy to prevent the transmission to the newborn. Caesarean section should be performed in the presence of herpetic lesions, and antiviral prophylaxis in the last weeks of pregnancy is recommended to suppress genital tract herpes simplex virus at the time of delivery. The diagnosis and early treatment of neonatal herpes simplex virus infections require a high index of suspicion, especially in the absence of skin lesions. It is recommended to rule out herpes simplex virus infections in those newborns with mucocutaneous lesions, central nervous system involvement, or septic appearance. The prognosis of newborns with skin, eye, and/or mouth disease in the high-dose acyclovir era is very good. Antiviral treatment not only improves mortality rates in disseminated and central nervous system disease, but also improves the rates of long-term neurodevelopmental impairment in the cases of disseminated disease. Interestingly, a 6-month suppressive course of oral acyclovir following the acute infection has improved the neurodevelopmental prognosis in patients with CNS involvement.

    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.

  18. Designing herpes viruses as oncolytics

    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.

    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.

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.

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

    2014-12-01

    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.

    Full Text Available The authors observed an injury caused by the sting of a false tocandira ant in the hand of an amateur fisherman and they describe the clinical findings and the evolution of the envenoming, which presented an acute and violent pain, cold sweating, nausea, a vomiting episode, malaise, tachycardia and left axillary's lymphadenopathy. About three hours after the accident, still feeling intense pain in the place of the sting, he presented an episode of great amount of blood in the feces with no history of digestive, hematological or vascular problems. The intense pain decreased after eight hours, but the place stayed moderately painful for about 24 hours. In that moment, he presented small grade of local edema and erythema. The authors still present the folkloric, pharmacological and clinical aspects related to the tocandiras stings, a very interesting family of ants, which presents the largest and more venomous ants of the world.A partir de um acidente causado pela picada de uma formiga falsa tocandira na mão de um pescador amador, os autores descrevem os achados clínicos locais observados, tais como edema, eritema e dor excruciante e a evolução do envenenamento, que cursou com fenômenos sistêmicos imediatos, como sudorese fria, náuseas, vômitos, mal estar, taquicardia e linfadenopatia axilar à esquerda. Após três horas, a dor intensa persistia e o paciente apresentou um episódio de hematoquesia, sem história anterior de enfermidades do trato digestivo, hematológicas ou vasculares. O uso de analgésicos (Tramal® 300 mg/dia, água quente e gelo não melhorou a dor, que arrefeceu em oito horas, tendo permanecido por cerca de 24 horas.

    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.

  18. Herpes simplex encephalitis : from virus to therapy.

    2011-06-01

    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.

    Herpes zoster is characterized by unilateral grouped vesicles along the distribution of a dermatome. A global recurrence rate as low as 0.5%∼6.2% has been reported for herpes zoster. 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.

    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.

    Herpesvirus infections are not uncommon in hematologic patients. Our first patient, diagnosed with chronic lymphatic leukemia, presented extensive genital herpes infection refractory to treatment with acyclovir and with a partial response to foscarnet, which had to be withdrawn due to systemic adverse effects. The second patient, diagnosed with follicular Hodgkin lymphoma, presented hypertrophic herpes infection refractory to treatment with acyclovir but that responded to intralesional cidofovir and topical imiquimod. As in other immunodepressed patients, herpesvirus infection in hematologic patients can present atypical manifestations, as well as resistance to treatments that act via the viral thymidine kinase. A high level of clinical suspicion is therefore needed to make an early diagnosis, together with extensive knowledge of the different treatments available. Copyright © 2017 AEDV.

    Full Text Available Over 150 sorts of viruses are capable of causing diseases of the respiratory ways. The virus infections have become the cost to be paid for urbanization and industrialization. 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.

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.

    Carlos Mena Frau

    Full Text Available Los avances tecnológicos de las últimas décadas han permitido determinar cada vez con mayor precisión, las dimensiones, forma y campo gravitacional de la Tierra. Estas nuevas tecnologías y sus métodos de observación y análisis, admiten el uso de distintos Sistemas Geodésicos de Referencia (SGR que hacen posible la descripción de posición de cualquier punto sobre la superficie terrestre con precisiones sub-métricas. Actualmente en Chile hay diversos SGR usados en la generación de productos cartográficos, tales como el Datum Provisorio Sudamericano de 1956 (PSAD56, el Datum Sudamericano de 1969 (SAD69 y el nuevo Sistema de Referencia Geocéntrico para las Américas (SIRGAS. Este último, a diferencia de los dos anteriores, es un sistema geocéntrico actual, compatible en precisión y exactitud con las modernas tecnologías de posicionamiento. Actualmente, el Instituto Geográfico Militar de Chile (IGM promueve la adopción del nuevo sistema SIRGAS e indica el modelo y los parámetros oficiales de transformación para la cartografía nacional a escala 1:50.000. Con la adopción de SIRGAS, una cantidad significativa de documentos cartográficos, en pleno uso actualmente, deberán ser transformados o adecuados al nuevo referencial geodésico. Existen diversos métodos y modelos, propuestos en la geodesia, para la transformación de valores de coordenadas asociados a un SGR en valores de coordenadas asociados a otro SGR. En el presente trabajo se realiza un análisis del impacto del cambio de referencial geodésico SIRGAS en la geometría de los rasgos representados en el sistema de proyección Universal Transversa de Mercator, para el caso de Chile continental sudamericano. Posteriormente, se definen modelos y parámetros alternativos al procedimiento clásico de transformación de coordenadas. Los resultados muestran que los modelos alternativos son eficaces en el caso de Chile.

    Full Text Available The bovine parasitic otitis has been reported in several states of Brazil. It is caused by rhabditiforms nematodes, attacking cattle Gir and Indubrasil breeds. The aim of this work was to describe the occurrence of the disease in animals of the cattle Gir breed in Rio Branco, State of Acre, Brazil. The animals belonged to the Station of Improvement and Animal Genetic Diffusion. Samples were collected from five of these individuals, with swabs aid, conditioned in plastic tubes and kept in alcohol 70%. The specimens were visualized using optical microscopy, and the morphometry was accomplished through a micrometrical ocular. The data were inserted in the Excel spreadsheet, running on Windows 7, and analyzed through descriptive statistics. The animals presented purulent secretion in the external ear canals, shook their heads, showed inquietude and sensibility to the touch during the clinical trials, when intense infestation was observed. One of the individuals died. Animal genetic improvement programs are negatively interfered by infestations like these. It was possible and opportune to find out the moment and place how such illness has entered in the state of Acre. This work aims to help reinforce the importance of future studies to report new cases in the state of Acre.

    Full Text Available There is evidence that environmental metal levels affect the immune function. In the particular case of the impact of heavy metals, information available suggests that the immune system is a target for low-dose Pb exposure. Among vertebrates it was shown that amphibians are capable of forming antibodies against a variety of antigens, causing several responses such as anaphylactic response and rejecting grafts. In this study, the production of antibodies was assessed against sheep red blood cells (SRBC in the anuran Bufo arenarum after six weekly injections of sublethal doses of lead (50 mg.kg-1, as lead acetate. Natural antibodies (natural heteroagglutinins were also quantified against SRBC. Both assessments were carried out employing an ELISA method developed to this end, measuring absorbance (A.

The only significant difference was found between initial and final samples from lead-treated toads (pExiste evidencia de que los niveles de metal ambientales afectan la función inmune. En el caso particular del impacto de metales pesados, la información disponible sugiere que el sistema inmune es un blanco para la exposición a bajas dosis de Pb. Entre los vertebrados, se ha mostrado que los anfibios son capaces de formar anticuerpos contra una variedad de antígenos, que causan diversas respuestas, tales como respuesta anafiláctica y rechazo de injertos. En este estudio, la producción de anticuerpos fue evaluada contra eritrocitos de oveja (EO en el anuro Bufo arenarum, luego de seis inyecciones semanales de dosis subletales de plomo (50 mg.kg-1, como acetato de Pb. Los anticuerpos naturales (heteroaglutininas naturales fueron también cuantificados contra EO. Ambas evaluaciones fueron llevadas a cabo empleando un método de ELISA desarrollado a este fin, midiendo la absorbancia (A. Para los anticuerpos anti-EO naturales, tanto en sapos controles (C como en sapos tratados con Pb (T, hubo una tendencia significativa a incrementar las absorbancias iniciales (C inicial: 0,69±0,39 A; T inicial: 0,54±0,30 A; la relación T/C tampoco mostró cambios. La única diferencia significativa se encontró entre las muestras inicial y final de los sapos tratados con plomo (p<0,014. Los niveles de anticuerpos anti-EO inmune de sapos inmunizados con EO mostraron un bajo incremento significativo (p<0,05 en los animales tratados con plomo (T final: 0,66±0,36 A, al compararse con sapos control (C final: 0,91±0,50 A al final del experimento. De este modo, se concluye que los cambios debidos a las dosis analizadas de Pb en los niveles de anticuerpos no pueden explicarse sólo sobre la base de un único mecanismo de acción del metal, sino como resultado de una conjunción de efectos sobre diferentes subpoblaciones de células inmunocompetentes. Estas diferentes respuestas sugieren que los factores que afectan los animales expuestos a un estímulo externo son diferentes de aquellos que influyen la respuesta en los animales silvestres.

    Full Text Available The issue of stock-outs in supermarkets is constantly being analyzed, since, in addition to losing sales, retailers impart a negative influence on the loyalty of customers to the brand of missing products, compromising operational results. Despite technologies that have been developed to cope with them, stock-out levels in the last sixty years have remained very high: out of every 100 items, eight are missing in the shelves. In this article, the objective was to identify the main causes of stock-outs and to create action plans to contain them. For this, a case study was carried out, using a qualitative methodology. A questionnaire was applied and interviews were conducted with the managers of five different sectors of a supermarket chain.

    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.

    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.

    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.

    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.

    Full Text Available Muchas especies de moluscos son hospedantes de diversos parásitos que provocan infecciones muy serias e incluso mortales en seres humanos y ganado. La esquistosomiasis extendida por 74 países, infecta a unos 200 millones de personas y está en segundo lugar, después de la malaria, como causa de la mortalidad humana originada por parásitos. La infección es causada por un platelminto que se desarrolla en caracoles de agua dulce y que desde el agua puede penetrar en la piel de un ser humano y desarrollarse dentro de sus órganos, produciendo distintos grados de infección, hasta provocar la muerte. Distintas especies de esos caracoles están extendidas por Centro América. El cólera, otra enfermedad que también es mortal, se ha encontrado en moluscos bivalvos comestibles colectados en el Golfo de Nicoya, que bordea Nicaragua y Costa Rica Estas epidemias se pueden combatir con diversos métodos de control de los caracoles hospedantes de parásitos.

    La paciente evolucionó favorablemente, sin presentar secuelas significativas. Se mantuvo vigilada a la paciente durante los 3 meses posteriores al cuadro. El diagnóstico de esta entidad es principalmente clínico; se sabe que uno de los factores de riesgo más importantes en este grupo de edad no es el inmunocompromiso, sino la infección por varicela zóster durante el primer año de vida. Es primordial realizar siempre una evaluación exhaustiva en los pacientes con estas características por las secuelas a largo plazo y el riesgo de ambliopía por deprivación en caso de leucomas corneales residuales. El curso clínico del herpes zóster oftálmico en niños inmunocompetentes es benigno si se trata oportunamente con aciclovir.

    Sanders, Jennifer E; Garcia, Sylvia E

    2014-01-01

    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.

    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.

  17. 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 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.

    1998-09-01

    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.

    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.

    2011-01-01

    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.

    Herpes simplex encephalitis (HSE) is the most frequent cause of sporadic necrotizing encephalitis in adults. 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.

  18. 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

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

    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.

    2017-07-01

    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.

    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.

    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

El método permite un análisis simple y objetivo de los resultados. La reacción enzimática es proporcional a la concentración de anticuerpos en el suero contra el antígeno somático-0, por tanto, el método es cuantitativo. Por lo demás, la técnica tiene un alto grado de especificidad para Salmonella typhi, ya que los sueros de pacientes con Salmonelosis causada por Salmonella enteritidis serotipos paratyphi A, B y typhimurium dieron resultados negativos, en forma similar a los presentados por el grupo control antes de la vacunación específica. Los resultados obtenidos con esta técnica permitieron definir el nivel de anticuerpos que puede presentar una población control supuestamente sana frente a los niveles inducidos por la enfermedad. Los resultados postvacunales en el grupo control mostraron títulos sorprendentemente bajos; un análisis de este fenómeno se presentó en forma amplia. Igualmente se proponen futuras investigaciones sobre este campo.

    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.

    2015-03-01

    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.

    Full Text Available We examined 40 sickly children with recurrent croup (RC — 28 and bronchial obstruction (ROB — 8, (RC + ROB — 4 aged from 18 months till 14 years. We found that high frequency of persistent herpes viruses usually occurs as associations with CMV, EBV and human herpes virus 6 type. We substantiated anti viral and immune corrective therapy in two schemes compared in efficacy: the 1st group was administered monotherapy with Viferon, and the 2nd group received combined therapy Viferon + Arbidol in doses according to the age during three months. We received a more expressed clinical immunologic effect from the therapy with decreased antigenic load and frequency of recurrence of RC and ROB with Viferon application in suppositories in combination with Arbidol per orally in the intermittent scheme during three months.

    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.

Tuberculous or bacterial meningitis, tuberculoma and abscess were at the top of the diagnosis list followed by Herpes simplex meningo-encephalitis (HSE). MRI showed abnormal signal intensity of left temporal lobe without significant post-contrast enhancement and midline shift. CSF examination was normal, gram stain and Ziehl-Neelsen stain showed no micro-organism, or acid fast bacilli. CSF for MTB PCR was negative. PCR DNA for Herpes simplex 1 on CSF was detected. Acyclovir was started and the patient was discharged after full recovery. A high index of suspicion is required for HSE diagnosis in Pakistan where other infections predominantly affect the brain and HSE may be overlooked as a potential diagnosis. (author)

    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.

    Full Text Available Objetivo. Conocer el panorama de las muertes por envenenamiento en niños de 0-14 años ocurridas en la República mexicana, entre 1979 y 1994. Material y métodos. Se utilizaron fuentes secundarias. Las variables analizadas fueron: edad, sexo, año, causa externa de traumatismos y envenenamientos, de la IX Clasificación Internacional de Enfermedades: E850-E858, E860-E869 y E905. Mediante un modelo de regresión Poisson se analizaron tendencias por causa específica y se obtuvieron riesgos relativos según edad, sexo y entidad federativa. Resultados. Hubo un total de 11 272 defunciones en menores de 15 años; las principales causas fueron el envenenamiento y las reacciones tóxicas causadas por plantas y animales venenosos (E905, el envenenamiento accidental por gas de uso doméstico y por monóxido de carbono (E868 y el envenenamiento accidental por otras drogas (E858. El grupo de edad que presentó los mayores riesgos, para las causas mencionadas, fue el de menores de un año con un riesgo relativo (RR de 29.6, IC95% 29.2-33.4; RR 3.47, IC95% 2.86-4.22, y RR 31.86, IC95% 24.8-40.9. El riesgo fue similar en ambos sexos, salvo para la causa E905. El estado de Aguascalientes se situó sistemáticamente entre los de mayor riesgo para todas las causas analizadas, mientras que Nuevo León siempre se ubicó entre los de riesgo más bajo. Conclusiones. El envenenamiento constituye una importante causa de muerte en los niños; el riesgo se incrementa al disminuir la edad. Considerando que esas muertes son potencialmente evitables y que la mayor parte de los envenenamientos ocurren en el hogar, para prevenirlos, se recomienda a los familiares vigilar y mantener fuera de peligro al niño. Por otra parte, la multicausalidad del fenómeno requiere que su prevención se realice desde una perspectiva multidisciplinaria que genere una cultura y un ambiente de seguridad en la sociedad.

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.

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

    Science.gov (United States)

    Lind, Liza; Studahl, Marie; Persson Berg, Linn; Eriksson, Kristina

    2017-07-10

    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.

    Full Text Available A amebíase é a segunda causa de morte entre as doenças parasitárias no mundo. Seu agente etiológico é o protozoário Entamoeba histolytica, que através da secreção de proteinases é capazes de destruir o tecido hospedeiro, matando as células-alvo por contato e fagocitando eritrócitos. Dessa forma, os trofozoítos invadem a mucosa intestinal, provocando a colite amebiana. Em alguns casos atravessam a mucosa e, através da circulação porta, chegam ao fígado, onde causam necrose constituída por poucos trofozoítos rodeados de hepatócitos mortos e debris celulares liquefeitos. Essa invasão está diretamente relacionada com a capacidade de síntese e a secreção de moléculas responsáveis pela virulência dos trofozoítos, como os amebaporos, as lectinas e as cisteína proteinases. O diagnóstico da infecção causada pelo patógeno é rotineiramente realizado através da microscopia óptica de amostras frescas ou espécimes fixados. Entretanto essa metodologia apresenta limitações, sendo incapaz de distinguir as espécies pertencentes ao complexo E. histolytica/E. dispar. A pesquisa de coproantígenos e a reação em cadeia da polimerase (PCR têm sido utilizadas para diferenciação desses protozoários em amostras fecais. No entanto, estudos mais aprofundados são necessários para maior compreensão sobre a relação parasita/hospedeiro, a proteômica e a genômica do protozoário, o desenvolvimento de vacinas e a real prevalência dessa infecção no Brasil e no mundo.Amebiasis is the second cause of death among parasitary diseases in the world.

    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.

    2016-06-27

    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.

Molecular mechanisms of infection: The last few decades have generated many new advances in our understanding of the mechanisms that drive HSV infection.

    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)

    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.

    Burning mouth syndrome is characterised by chronic orofacial burning pain. No dental or medical cause has been found. We present a case of burning mouth syndrome of 6 months duration in a healthy 65-year-old woman, which was associated with high copy numbers of herpes simplex virus type 1 (HSV-1) DNA in the saliva. Her pain resolved completely after antiviral treatment with a corresponding absence of salivary HSV-1 DNA 4 weeks and 6 months later. 2015 BMJ Publishing Group Ltd.

    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

    Herpes zoster is an infectious vesicular skin rash in a dermatomal distribution caused by Varicella zoster virus. It occurs very uncommonly in sacral dermatomes. We describe a case with rash on penis and scrotum due to involvement of S2 dermatome in a young male. The disease followed an uneventful course and the patient recovered completely without any sequelae or complications. This case is being presented to highlight its unusual location and to discuss differentiation from another viral infection commonly seen at this site. (author)

    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.

    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. Este resultado foi estatisticamente significante

    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.
