ABSTRACT

RESUMEN El herpes zóster es una afección infrecuente en lactantes, con una incidencia de 0,74/1 000 habitantes. Se produce por la reactivación del virus de la varicela zóster, tras una primoinfección por varicela. Puede ocurrir intraútero, por lo que resulta relevante conocer los antecedentes maternos. El diagnóstico es clínico y si se realiza de forma adecuada reduce el riesgo de complicaciones. El tratamiento en los niños es sintomático, porque su evolución es más favorable que en los adultos. Debido a la rareza de esta entidad, se presentan tres casos de herpes zóster en lactantes de 4, 6 y 11 meses de edad, que acudieron con lesiones y evolución típica de esta enfermedad al Hospital Pediátrico Provincial Docente Eliseo Noel Caamaño, de Matanzas, entre septiembre y octubre de 2017 (AU).


ABSTRACT Herpes zoster is an uncommon affection in infants, with an incidence of 0.74/1 000 inhabitants. It is produced by the reactivation of the varicella-zoster virus, after a primary infection by varicella. This can occur inside the uterus, making it relevant to know maternal antecedents. The diagnosis is clinical, and if it is made in an appropriate way, reduces complication risk. The treatment in children is symptomatic because its evolution is more favorable than in adults. Due to the rareness of this entity, we present three cases of herpes zoster in nurslings aged 4, 6 and 11 moths who assisted the Teaching Pediatric Hospital Eliseo Noel Caamaño, of Matanzas, with lesions and typical evolution of this disease in the period September-October 2017 (AU).

ABSTRACT

Antimony compounds are the cornerstone treatments for tegumentary leishmaniasis. The reactivation of herpes virus is a side effect described in few reports. We conducted an observational study to describe the incidence of herpes zoster reactivation during treatment with antimony compounds. The global incidence of herpes zoster is approximately 2.5 cases per 1,000 persons per month (or 30 cases per 1,000 persons per year). The estimated incidence of herpes zoster in patients undergoing antimony therapy is higher than previously reported.

ABSTRACT

Since the introduction of varicella vaccination in India, surveillance of circulating VZV strains has gained significance. Differentiating wild-type VZV strains from the Oka vaccine strain can be achieved only by molecular genotyping methods. The development of PCR methods for VZV strain differentiation has been hampered by the fact that the VZV genome is highly conserved. We used VZV ORF 62 PCR-RFLP analysis to identify and differentiate wild-type VZV strains in India from the Oka vaccine strain. Digestion of VZV ORF 62 amplicons with SmaI, enabled accurate strain differentiation; the Oka strain was positive for three SmaI sites, compared to two SmaI sites in the wild-type VZV strains that we tested.

ABSTRACT

PURPOSE: To document etiology and predictive value of clinical diagnosis in laboratory confirmed viral diseases. METHODS: Reports of culture-positive cases of samples collected from patients presenting from January 1987 - December 2001 were evaluated. RESULTS: One thousand nine hundred and sixty-four (1964) cultures were submitted during 1987-2001. Twenty-six percent were positive (514). Human herpesvirus 1 was the most frequent agent isolated from all positive culture (56 percent). Adenovirus was the most common virus isolated from conjunctiva (66 percent), human herpesvirus 1 from lid and cornea (76 percent, 88 percent) and cytomegalovirus from vitreous (27 percent). Some unusual pathogens were recovered from conjunctiva as cytomegalovirus and from cornea as adenovirus, enterovirus and cytomegalovirus. Recognition of common viral syndromes was human herpesvirus 1 (88 percent), epidemic keratoconjunctivitis (88 percent), acute hemorrhagic conjunctivitis (70 percent) and varicella zoster virus (100 percent). However, some misdiagnosed cases were observed. Thirteen percent of conjunctivitis thought to be caused by herpes were due to adenovirus, 3.2 percent to Enterovirus, 3.2 percent to varicella zoster virus and 3.2 percent to human cytomegalovirus. Also, 5 percent of cases with a clinical diagnosis of herpes keratitis were caused by adenovirus and 2.7 percent by enterovirus. Finally, 4.8 percent of cases thought to be adenovirus conjunctivitis were herpes conjunctivitis. CONCLUSIONS: Human herpesvirus 1 remains the most frequently isolated virus from ocular sites in general (56 percent). Nonherpetic corneal isolates were in decreasing order: adenovirus, enterovirus and cytomegalovirus. Clinical and laboratory correlation was less than 90 percent. The most misdiagnosed cases were herpes conjunctivitis and keratitis, some cases of adenovirus conjunctivitis some cases of acute hemorrhagic conjunctivitis. It is essential that a rapid and...


OBJETIVOS: Documentar a etiologia e prever a importância do diagnóstico clínico em doenças virais oculares confirmadas em laboratório. MÉTODOS: Todos os relatórios de pacientes com cultura viral positiva durante o período de janeiro 1987 - dezembro 2001 foram analisados. RESULTADOS: Quinhentos e quatorze (514) casos foram encontrados. Em geral, herpesvírus 1 humano foi o agente mais freqüentemente isolado. Adenovírus foi o vírus mais comumente isolado da conjuntiva (66 por cento), herpesvírus 1 humano das pálpebras e córnea (76 por cento, 88 por cento respectivamente) e citomegalovírus do vítreo (27 por cento). Alguns agentes não usuais foram isolados da conjuntiva como citomegalovírus e da córnea como adenovírus, enterovírus e citomegalovírus. Reconhecimento das síndromes virais comuns foi: herpervírus 1 humano (88 por cento), ceratoconjuntivite epidêmica (88 por cento), conjuntivite aguda hemorrágica (70 por cento). Porém, alguns casos com diagnóstico incorreto foram observados. Treze por cento das conjuntivites com diagnóstico de herpes foram causadas por adenovírus, 3,2 por cento por enterovírus, 3,2 por cento por varicella zoster vírus e 3,2 por cento por citomegalovírus. Também, 5 por cento dos casos com diagnóstico clínico de ceratite herpética eram adenovírus e 2,7 por cento enterovírus. Além disso, 4,8 por cento dos casos em que se pensaram em conjuntivite por adenovírus, eram conjuntivite por herpes. Finalmente, 30 por cento dos casos em que se diagnosticaram conjuntive hemorrágica aguda, o agente etiológico era adenovírus. CONCLUSÃO: Em geral herpesvírus humano 1 continua a ser o vírus mais comum encontrado nas infecções oculares (56 por cento). Agentes não herpéticos isolados da córnea foram em ordem decrescente: adenovírus, enterovírus e citomegalovírus. A correlação entre o diagnóstico clínico e laboratorial foi menor do que 90 por cento. Um diagnóstico rápido e específico é essencial em casos de apresentações virais atípicas...

ABSTRACT

Se presenta una revisión de la literatura sobre herpesvirus en relación con el herpes zoster varicela. Se estudió una serie de 2,799 pacientes que presentaron esta afección y fueron atendidos en la consulta externa y hospiralización del Centro Médico Nacional 20 de Noviembre, ISSSTE, en el periodo comprendido entre 1984 y 1997. Sesenta y siete pacientes se catalogaron como sanos por no presentar padecimiento subyacente de inmunocompromiso como neoplasias malignas, transplantes, SIDA diabetes mellitus, etc. La forma de presentación, evolución y/o complicaciones no varió significativamente en relación con otras fuentes consultadas, a excepción de la diabetes mellitus, que en nuestro país es una enfermedad con gran incidencia

ABSTRACT

Estudo de um caso de herpes zoster acometendo paciente jovem que evoluiu inicialmente com ceratite puntacta e diminuição da sensibilidade corneana, para, em seguida, desenvolver uveite anterior severa e paralisia total de músculos extrínsecos extra-oculares e neurite óptica- Síndrome do Ápice-Orbital. Apresentamos, neste caso, os aspectos terapêuticos e evolutivo da doença, abordando a necessidade de se pesquisar sempre a presença do HIV em pacientes jovens acometidos de herpes zoster, pode o mesmo representar a primeira manifestação sistêmica da AIDS.
