ABSTRACT

Introducción: Streptococcus mutans participa en el origen y progreso de la caries dental, una de las enfermedades más prevalentes a nivel mundial. Su control requiere métodos seguros y accesibles para la población. Myrciaria dubia (Kunth) McVaugh (Myrtaceae) (camu camu) es un árbol nativo de la amazonía peruana. La capacidad antimicrobiana de los componentes de su fruto ya se ha comprobado. Objetivo: Evaluar la actividad antibacteriana in vitro del extracto hidroetanólico de M. dubia contra S. mutans ATCC 35658. Métodos: Investigación experimental con posprueba y grupos controles. El extracto de la pulpa del fruto de M. dubia se obtuvo mediante maceración hidroetanólica. Las concentraciones evaluadas fueron 25 mg/mL, 50 mg/mL y 75 mg/mL. La capacidad antibacteriana se determinó mediante el método de difusión en disco. Gluconato de clorhexidina 0,12 por ciento fue el control positivo y el dimetilsulfóxido al 1 por ciento el control negativo. Resultados: La actividad antibacteriana se incrementó de manera directamente proporcional a la concentración del extracto. La concentración de 75 mg/mL mostró una media de inhibición de 18,2 ± 0,774 mm, seguido de la concentración de 50 mg/mL con una media de inhibición de 14,6 ± 1,055 mm y la concentración de 25 mg/mL con un halo de inhibición promedio de 10,1± 0,833 mm. La zona de inhibición del control positivo fue de 16,5 ± 0,516 mm. Existe diferencia estadísticamente significativa entre la concentración de 75 mg/mL y el control positivo (p< 0,05). Conclusiones: El extracto hidroetanólico de M. dubia muestra actividad antibacteriana in vitro de tipo bactericida sobre S. mutans ATCC 35668(AU)


Introduction: Streptococcus mutans is involved in the genesis and progress of dental caries, one of the most prevalent diseases worldwide, whose control requires safe methods accessible to the population. Myrciaria dubia (Kunth) McVaugh (Myrtaceae) (camu camu) is a tree native to the Peruvian Amazon. The antimicrobial capacity of the components of its fruit has already been verified. Objective: Evaluate the in vitro antibacterial activity of M. dubia hydroethanolic extract against S. mutans ATCC 35658. Methods: An experimental study was conducted with post-test analysis and control groups. The extract from the pulp of the fruit of M. dubia was obtained by hydroethanolic maceration. The concentrations evaluated were 25 mg/mL, 50 mg/mL and 75 mg/mL. Antibacterial capacity was determined by the disc diffusion method. The positive control was 0.12 percent chlorhexidine gluconate, whereas the negative control was 1 percent dimethyl sulfoxide. Results: The antibacterial activity increased directly proportional to the concentration of the extract. The concentration of 75 mg/mL showed a mean inhibition of 18.2 ± 0.774 mm, followed by the concentration of 50 mg/mL with a mean inhibition of 14.6 ± 1.055 mm and the concentration of 25 mg/mL with an average inhibition halo of 10.1 ± 0.833 mm. The zone of inhibition of the positive control was 16.5 ± 0.516 mm. There is a statistically significant difference between the concentration of 75 mg / mL and the positive control (p< 0.05). Conclusions: The M. dubia hydroethanolic extract displays in vitro antibacterial bactericidal activity against S. mutans ATCC 35668(AU)

ABSTRACT

Introducción: La encía queratinizada es un componente importante del complejo mucogingival. Su ausencia puede deberse a recesiones gingivales, traumas, caries radicular, entre otras. La técnica de injerto gingival libre es considerada el estándar de oro, por ser una técnica óptima para aumentar la extensión del vestíbulo y el ancho del tejido queratinizado por sus altas tasas de éxito y predictibilidad clínica. Objetivo: El propósito de este caso clínico fue evaluar el uso de una modificación de la técnica del injerto gingival libre. Presentación de caso: El caso clínico incluyó aumento de la profundidad del vestíbulo y de la encía queratinizada en ambas zonas del sector anteroinferior, para lo cual se utilizaron las dos hemiarcadas del paladar como la zona dadora del injerto (doble injerto). El caso utilizó un doble injerto gingival libre como técnica novedosa para el aumento gingival. Después de dos meses de cicatrización, se observó reducción de la recesión gingival y un aumento notorio del ancho de la encía queratinizada. Conclusiones: La técnica modificada de doble injerto gingival libre, es una buena alternativa para aumentar el grosor de la encía queratinizada en el sector anteroinferior, además de reducir el tiempo posoperatorio y generar una cicatrización uniforme a nivel de la línea mucogingival(AU)


Introduction: Keratinized gingiva is an important component of the mucogingival complex. Its absence may be due to gingival recessions, trauma, root caries, among others. The free gingival graft technique is considered the gold standard, as it is an optimal technique to increase the extension of the vestibule and the width of the keratinized tissue due to its high success rates and clinical predictability. Objective: The purpose of this clinical case was to evaluate the use of a modification of the free gingival graft technique. Case report: The clinical case included an increase in the depth of the vestibule as well as the keratinized gingiva in both areas of the anteroinferior sector, for which the two hemiarchates of the palate were used as the graft donor area (double graft). The case used a free double gingival graft as a novel technique for gingival augmentation. After two months of healing, a reduction in the gingival recession was observed, as well as a noticeable increase in the width of the keratinized gingiva. Conclusions: The modified free double gingival graft technique is a good alternative to increase the thickness of the keratinized gingiva in the anteroinferior sector, in addition to reducing the post-operative time and generating uniform healing at the level of the mucogingival line(AU)

ABSTRACT

Resumen La linfocitopenia T CD4 idiopática (LCI) es un síndrome clínico inusual que se caracteriza por un déficit de células T CD4+ circulantes en ausencia de infección por VIH u otra condición de inmunosupresión. Los pacientes con dicha enfermedad pueden presentarse asintomáticos o con infecciones oportunistas, las más frecuentes son por criptococo, micobacterias o virales como herpes zoster. Presentamos el caso de un hombre de 32 años, sin antecedentes, en quien se descartó infección por retrovirus, con recuento de linfocitos T CD4+ menor a 300 células/m3; se diagnosticó LCI posterior al diagnóstico de criptococomas cerebrales mediante hallazgos imagenológicos los cuales fueron congruentes con estudios microbiológicos.


Summary Idiopathic CD4 T lymphocytopenia (ICL) is an unusual clinical syndrome characterized by a deficit of circulating CD4 + T cells in the absence of HIV infection or another immunosuppression condition. Patients with this disease may present asymptomatic or with opportunistic infections, the most frequent are cryptococcus, mycobacteria or viral such as herpes zoster. We present a case of a 32-year-old man with no prior disease, in whom retrovirus infection was discarded, with CD4 + T lymphocyte count less than 300 cells/m3; ICL was diagnosed after the diagnosis of brain cryptococomas by imaging findings which were consistent with microbiological studies.

ABSTRACT

OBJECTIVE: To describe the clinical features of herpes zoster in adult patients treated at a large tertiary care hospital in Brazil over a 5-year period. METHODS: The medical records of suspected herpes zoster cases (based on ICD-10 codes) were identified for full review. Convenience sampling was used to select the medical records from a tertiary hospital in São Paulo. We collected data about co-existing medical conditions, medication use, herpes zoster-related clinical features and outcomes, and healthcare resource utilization. RESULTS: A total of 249 individuals whose first episode of herpes zoster occurred between 2010 and 2014 were included. The mean patient age was 55 years (range 18­96), and the majority were women (63.05%) and aged ≥ 50 years (63.86%). Medical comorbidities were reported in 92.77%, including diabetes (19.68%) and HIV infection (7.63%). Current/recent use of immunosuppressive agents was reported in 31.73%. A total of 65.86% of the patients were hospitalized: 102 patients (40.96%) were admitted for herpes zoster management, while 62 (24.90%) were already receiving inpatient care. The mean hospital length of stay was 16.60 days. One-third (34.14%) were managed as outpatients. Postherpetic neuralgia was reported as a complication in 18.07%. CONCLUSIONS: This retrospective descriptive study found a high frequency of herpes zoster episodes in older adults with comorbidities who sought medical care at a tertiary hospital. These results also underscore the importance of understanding the epidemiology of this disease and developing control strategies for these at-risk populations in Brazil.


OBJETIVO: Descrever as características clínicas do herpes zoster em pacientes adultos atendidos em um grande hospital terciário no Brasil por um período de cinco anos. METODOLOGIA: Os casos suspeitos de herpes zoster (com base nos códigos da CID-10) foram identificados para revisão completa dos prontuários. Foi realizada uma amostragem por conveniência para selecionar os prontuários de interesse em um hospital terciário em São Paulo. Foram coletadas informações de prontuários médicos sobre condições coexistentes, características clínicas e uso de medicamentos relacionados ao herpes zoster (como primeiro episódio ou episódio de herpes zoster recorrente) e uso de recursos de saúde. RESULTADOS: Entre 2010 e 2014, 249 indivíduos com um primeiro episódio de herpes zoster foram incluídos, com uma idade média de 55 anos (variando de 18 a 96 anos). A maioria era do sexo feminino (63,05%) e com idade ≥ 50 anos (63,86%). Comorbidades médicas foram relatadas em 92,77% dos pacientes, incluindo diabetes (19,68%) e infecção por HIV (7,63%); o uso atual / recente de agentes imunossupressores foi relatado em 31,73%. Hospitalização foi relatada em 65,86% dos casos; 102 pacientes (40,96%) foram admitidos para o tratamento do episódio de herpes zoster e 62 pacientes (24,90%) já estavam recebendo atendimento hospitalar. O tempo médio de permanência no hospital foi de 16,60 dias. Um terço (34,14%) de todos os casos foi tratado ambulatorialmente. A neuralgia pós-herpética foi relatada como complicação em 18,07% dos casos. CONCLUSÕES: Os resultados do presente estudo descritivo retrospectivo demonstram alta frequência de episódios de herpes zoster em idosos com comorbidades, buscando atendimento médico em um hospital terciário. Esses resultados também ressaltam a importância de entender a epidemiologia dessa doença e considerar as estratégias de controle nas populações de risco no Brasil.

ABSTRACT

Abstract Ramsay Hunt Syndrome (RHS), also known as herpes zoster oticus, is caused by the reactivation of varicella zoster virus (VZV) in the geniculate ganglion of the facial nerve. Herein, we report a case of Ramsey Hunt Syndrome in a patient after antimonial treatment for Cutaneous Leishmaniasis. The patient presented with microvesicles grouped on an erythematous base, starting in the neck and ascending towards the scalp margin on the right side of the head. The patient also developed grade V peripheral facial palsy the day after initiating the herpes zoster treatment, this outcome corroborated the assumption of Ramsey Hunt Syndrome.

ABSTRACT

Resumen Introducción: La infección genital por el Virus de Papiloma Humano (VPH) se ha asociado con el cáncer cérvicouterino (CCE) al provocar la aparición de lesiones precursoras de cáncer en la zona de transformación de la unión escamo-columnar del cuello uterino. Existen más de 100 tipos de VPH, clasificados en bajo riesgo oncogénico (VPH-BR) y alto riesgo oncogénico (VPH-AR). Estudios reportan la infección por genotipos de alto riesgo en el 100% de los CCE. En Venezuela, el 67,7% de los CCE, se relacionan con el genotipo de VPH-AR 16. Objetivo: Detectar la presencia de VPH en pacientes con cambios citológicos cervicouterino. Metodología: Se incluyeron 49 pacientes que presentaban cambios citológicos, se tomaron las muestras de la región endocervical y exocervical para la detección y genotipificación del virus mediante la técnica de Multiple PCR. Resultados: Las alteraciones citológicas presentes fueron Células Escamosas Atípicas (69,4%), Células Glandulares Atípicas (4,1%), Lesión Escamosa Intraepitelial de Bajo Grado (16,3%), y Lesión Escamosa Intraepitelial de Alto Grado (10,2%). La detección molecular demostró que 16,3% presentaba VPH, 62,5% correspondían a VPH-AR, 25% a VPH-BR, 12,5% al genotipo 16 y no se detectó el genotipo 18. Se reportó un solo caso de coinfección. Conclusiones: A diferencia de otros estudios, no se encontró una relación estadísticamente significativa entre la presencia del virus y la aparición de cambios citológicos cervicouterino en esta población. No obstante, se detectaron genotipos de alto riesgo oncogénico, lo que puede traducirse en una mayor incidencia de cáncer cervicouterino a futuro.


Abstract Introduction: Genital infection by the Human Papilloma Virus (HPV) has been associated with cervical cancer (CC) since it causes the appearance of precursor cancer lesions in the transformation area of ​​the squamous-columnar junction of the cervix. There are more than 100 types of HPV that are classified as low oncogenic risk (LR-HPV) and high oncogenic risk (HR-HPV). Studies report that the infection by high-risk genotypes is present in 100% of CC. In Venezuela, 67.7% of CC is related to the HPV-16 genotype. Objective: This study seeks to detect the presence of HPV in patients with cervical cytological cell changes. Methodology : Forty-nine patients with cytological changes were studied. The endocervical and ectocervical areas were sampled to detect and genotype the virus by using the Multiplex PCR technique. Results: The cytological alterations presented were: Atypical Squamous Cells (69.4%), Atypical Glandular Cells (4.1%), Low-grade Squamous Intraepithelial Lesion (16.3%) and High-grade Squamous Intraepithelial Lesion (10.2%). Besides, the general molecular detection showed that 16.3% had HPV, 62.5% of it corresponded to HR-HPV, 25% to LR-HPV, and 12.5% ​​to genotype 16. The genotype 18 was not detected, and only one co-infection case was reported. Conclusions: Unlike other studies, a statistically significant relationship was not found between the virus presence and the appearance of cervical cytological cell changes in this population. However, genotypes with high oncogenic risk were detected, which may lead to a higher incidence of cervical cancer in the future.

ABSTRACT

La varicela es una enfermedad infecto-contagiosa, producida por el virus varicela-zoster (VVZ); es un virus alfaherpes que se relaciona más estrechamente con el virus del herpes simple, se presenta cuando el virus entra en contacto con la mucosa del tracto respiratorio superior o la conjuntiva de una persona susceptible, la transmisión de persona a persona se puede presentar por contacto directo con lesiones de VZV o por propagación en el aire. La reinfección con VZV es rara. El período de incubación es de 10 a 21 días; los síntomas que generalmente se presentan son fiebre, malestar general, anorexia, dolor de cabeza y posteriormente vesículas claras, pruriginosas en las primeras etapas, llenas de líquido que evolucionan a costras. La complicación más común de la varicela es la sobreinfección bacteriana de las lesiones cutáneas causadas con mayor frecuencia por Staphylococcus aureus y Streptococcus del grupo A, pero también es posible encontrar linfadenitis y abscesos subcutáneos. Cuando la varicela se presenta durante los últimos días de gestación (<5 días) o 2 días después del parto, existe un riesgo aproximado de 20% de presentar varicela neonatal.


The Varicela is an infectious-contagious disease, caused by the varicella-zoster virus (VZV); It is an alphaherpes virus that is more closely related to the herpes simplex virus, it occurs when the virus comes into contact with the mucosa of the upper respiratory tract or the conjunctiva of a suscep-tible person, transmission from person to person can occur by contact Direct with VZV or airborne injuries. Reinfection with VZV is rare. The incubation period is from 10 to 21 days; The symptoms that generally appear are fever, general malaise, anorexia, headache and later clear, itchy vesicles in the early stages, filled with fluid that evolve to crusts. The most common complication of varicela is bacterial superinfection of the cutaneous lesions most frequently caused by group A Staphylococcus aureus and Streptococcus, but it is also possible to find lymphadenitis and subcutaneous abscesses. When chickenpox occurs during the last days of gestation (<5 days) or 2 days after delivery, there is an approximate 20% risk of developing neonatal varicela

ABSTRACT

Herpes zoster classical clinical presentation is the acute onset of multiple vesicles over an erythematous base, disposed over one or two dermatomes with up to 20 vesicles located outside the main dermatome. Disseminated herpes zoster is an atypical and rare form of presentation of herpes zoster, which manifests with lesions beyond the described territory. It occurs mainly in patients with some type of cellular immunosuppression. The diagnosis is made with the medical history and physical examination, however, it should be confirmed with laboratory tests. Treatment must be initiated early to avoid serious complications, such as bacterial infection of the lesions, post-herpetic neuralgia, or even central nervous system involvement. The drug of choice is intravenous acyclovir that must be maintained until the cessation of the appearance of new lesions, and then switch to its oral presentation for another 5-7 days. Disseminated herpes zoster mortality rounds 5-15%. There are varicella-zoster virus vaccines, that have been shown to reduce the incidence of herpes zoster relapses, however its utility to disseminated herpes zoster is uncertain and further studies are required. We present the case of a male patient with a history of rheumatoid arthritis who consults with multiple vesicles distributed throughout his body. (AU)

ABSTRACT

An increase in the number of patients with infectious diseases in Korea, can be attributed to various factors, such as the prevalence of new infectious diseases of the 21st century, the re-emergence of past infectious diseases, an increase in the number of elderly individuals, patients with chronic diseases, immune deficiency, and globalization. In this context, vaccination becomes vital for the adult population. Although, the guidelines for adult immunization are currently being updated, the rate of adult vaccination remains lower than that of infant vaccination. At present, the major challenges for increasing the rate of adult immunization include negative views on the need for some immunizations and a lack of understanding of group immunity among the youth. Consequently, a successful immunization program will be required to direct efforts towards educating patients and spreading awareness. Based on the current guidelines and practical applications, varicella zoster; Japanese encephalitis; tetanus, diphtheria, and pertussis; pneumococcus; measles, mumps, and rubella; and hepatitis A vaccines could effectively be considered for adult vaccination.

ABSTRACT

Resumen Objetivo: Estimar las frecuencias de mutaciones y de polimorfismos adicionales asociados con resistencia a los fármacos inhibidores de la integrasa del virus de inmunodeficiencia humana tipo 1 (VIH-1). Metodología: Estudio descriptivo, de corte transversal, en individuos VIH-1 positivos de la ciudad de Medellín, quienes no habían recibido tratamiento antirretroviral. En ellos se determinó, a través del método de 2-dideoxinucleótidos y el sistema ABI3730XL, la secuencia del gen de la integrasa del VIH-1 a partir del ARN viral circulante, la cual fue analizada en la base de datos de resistencia a medicamentos antirretrovirales de la Universidad de Stanford y según reportes de literatura científica. Resultados: Se encontraron las siguientes mutaciones (con sus respectivas frecuencias): una mutación mayor, E138K (1/46), tres mutaciones accesorias G163E (3/46), L74I (3/50) y E157Q (2/48), una mutación no polimórfica A128T (1/49) y otras dos mutaciones potencialmente asociadas con resistencia a inhibidores de integrasa S230N (9/39) y S119P/R/T (4/47, 2/47 y 14/47, respectivamente). Conclusiones: En las secuencias analizadas, llama la atención la presencia de al menos una mutación asociada a resistencia a inhibidores de integrasa en el 14% de los individuos estudiados, sugiriendo una pobre presión selectiva de este tipo de fármacos en la población viral circulante en la zona.


Abstract Aim: To estimate the frequencies of major and accessory mutations, as well as additional polymorphisms associated with resistance to human immunodeficiency virus type 1 (VIH-1) integrase strand transfer inhibitors. Materials and methods: Descriptive cross-sectional study, focused on HIV-1 positive individuals from Medellín, recruited between 2013 and 2015, and that had not received antiretroviral therapy. In these patients, the sequence from HIV-1 integrase was determined from circulating viral RNA through Sanger chain termination method with the ABI3730XL system, and the sequences were analyzed using the HIV Drug Resistance Database from the University of Stanford, together with previous literature reports. Results: The following mutations associated with resistance to integrase strand transfer inhibitors, along with its respective frequencies, were found: one major mutation, E138K (1/46), three accessory mutations, G163E (3/46), L74I (3/50) and E157Q (2/48); one non-polymorphic mutation, A128T (1/49); and two mutations potentially associated with resistance to integrase strand transfer inhibitors, S230N (9/39) and S119P/R/T (4/47, 2/47 and 14/47, respectively). Conclusions: In the sequences analyzed, it is noteworthy the presence of at least one mutation related with resistance to integrase inhibitors in 14% of the studied patients, suggesting a poor selective pressure of this kind of drugs in the circulating viral population in our region.

ABSTRACT

El presente trabajo es una revisión de más de 40 años de investigación sobre los aspectos epidemiológicos, socioeconómicos y clínicos de la Enfermedad de Chagas en el Departamento Uruguay (Provincia de Entre Ríos). Se resumen las investigaciones sobre la presencia de vectores triatominos en viviendas urbanas y rurales donde se procedió a su identificación y búsqueda de Trypanosoma cruzi. Se describió la seroprevalencia de la enfermedad y su evolución a lo largo del tiempo. Se agregaron también aspectos cardiológicos y gastroenterológicos de pacientes en el período crónico de la enfermedad. La presencia de triatominos derivó en campañas de fumigación y de educación sanitaria, que provocaron un marcado descenso en el número de vectores capturados en los años siguientes. También se destacó el descenso de la seroprevalencia de la enfermedad de Chagas a través del tiempo, debido a las campañas de fumigación, educación sanitaria, controles en banco de sangre y embarazadas, mejora de las técnicas utilizadas y la aparición de tratamientos efectivos contra el parásito. Los estudios cardiológicos y gastroenterológicos de los pacientes crónicos mostraron alteraciones dentro de lo esperado para este estadio de la enfermedad. También se describió la detección de personas infectadas con acceso al tratamiento y los estudios cardiológicos y gastroenterológicos realizados en pacientes en estadio crónico. Por último, se considera que, globalmente, los estudios realizados en la zona han colaborado en lograr que la Provincia de Entre Ríos fuera declarada libre de transmisión vectorial en 2012.


This is a review of more than 40 years of research on the epidemiological, socioeconomic and clinical aspects of Chagas disease in the Department of Uruguay (Entre Ríos province). Research on the presence of triatomine vectors in urban and rural housing is summarized here.These vectors were identified and Trypanosoma cruzi was searched for. . The seroprevalence of the disease and its evolution over time were described. Cardiological and gastroenterological aspects of patients in the chronic period of the disease were also added. The presence of triatomines resulted in fumigation and health education campaigns, which caused a marked decrease in the number of vectors captured in the following years. The decrease in the seroprevalence of Chagas disease over time was also highlighted, due to fumigation campaigns, health education, blood bank and pregnant women controls, improvement of the techniques used and the development of effective treatments against the parasite. Cardiological and gastroenterological studies of chronic patients showed the abnormalities expected for this stage of the disease. The detection of infected persons with access to treatment and cardiological and gastroenterological studies performed in patients with chronic stage were also described. Finally, it is considered that, globally, the studies carried out in the area have helped to ensure that the Province of Entre Ríos be declared free of the vector transmission in 2012.


Este trabalho é uma revisão de mais de 40 anos de pesquisa sobre os aspectos epidemiológicos, socioeconômicos e clínicos da doença de Chagas no Departamento Uruguai (província de Entre Ríos). São resumidas as pesquisas sobre a presença de vetores de triatomíneos em moradias urbanas e rurais, onde foram identificados e pesquisados por Trypanosoma cruzi nelas. A soroprevalência da doença e sua evolução ao longo do tempo foram descritas. Também foram adicionados aspectos cardiológicos e gastroenterológicos dos pacientes no período crônico da doença. A presença de triatomíneos resultou em campanhas de fumigação e educação sanitária, o que causou uma redução acentuada no número de vetores capturados nos anos seguintes. Também foi destacada a diminuição da soroprevalência da doença de Chagas através do tempo, devido às campanhas de fumigação, educação sanitária, controles em bancos de sangue e gestantes, melhora das técnicas utilizadas e surgimento de tratamentos eficazes contra o parasita. Estudos cardiológicos e gastroenterológicos de pacientes crônicos mostraram alterações dentro do esperado para esse estágio da doença. Também foram descritas a detecção de pessoas infectadas com acesso ao tratamento e estudos cardiológicos e gastroenterológicos realizados em pacientes em estágio crônico. Por fim, consideramos que, globalmente, os estudos realizados na área ajudaram a garantir que a Província de Entre Ríos fosse declarada livre de transmissão vetorial em 2012.

ABSTRACT

El virus herpes felino tipo 1 genera múltiples problemas y el gato termina con consecuencias que afectan su futura calidad de vida. Este virus está distribuido en todo el mundo y es de fácil transmisión y dado que es un patógeno latente, continúa propagándose sin control a toda la población de gatos. El diagnóstico se basa en los signos clínicos, existiendo hoy en Chile solo un método de diagnóstico de laboratorio específico, implementado para identificar el agente, que no se usa regularmente en la clínica de animales pequeños. Así, el tratamiento y diagnóstico generalmente se basan en el conocimiento y la experiencia del médico veterinario, sin dejar una confirmación real sobre qué agente está causando los síntomas. Esta investigación propuso un método de diagnóstico molecular alternativo a la detección del gen de la timidina quinasa viral, para el cual se seleccionaron gatos menores de 1 año de edad, con síntomas compatibles con una infección con el virus del herpes felino. El método de la Reacción en Cadena de la Polimerasa (PCR) se utilizó para detectar el gen de la glicoproteína B del virus herpes felino tipo 1, seguido de la determinación del porcentaje de identidad de nucleótidos (PIN) respecto a los datos oficiales del GenBank®. De los 11 gatos estudiados, en solo uno de ellos se pudo amplificar un segmento que correspondía al gen de la glucoproteína B. El PIN resultante (>96 por ciento) confirma que la secuencia obtenida corresponde al gen de la glicoproteína B tipo 1 del virus del herpes felino y se discute la eficiencia del método implementado(AU)


The feline herpesvirus type 1, generates multiple problems and the cat ends with consequences that affect its future quality of life. This virus is distributed throughout the world and is easily transmitted and since it is a latent pathogen, it continues to spread uncontrollably to the entire cat population. The diagnosis is based on clinical signs, today there is only a specific laboratory diagnostic method implemented in Chile to identify the agent, which is not used regularly in the clinic of small animals. Thus, the treatment and diagnosis are usually based on the knowledge and experience of veterinarian without leaving a real confirmation about which agent is causing the symptoms. This research proposed a molecular diagnostic method alternative to timidine kinase detection gene, for which cats under 1 year of age were selected, with symptoms compatible with an infection with the feline herpesvirus. The Polymerase Chain Reaction (PCR) method was used to detect the feline herpesvirus type 1 glycoprotein B gene, followed by the determination of the percentage of nucleotide identity (NIP) from official GenBank® data. Of the 11 cats studied, only one of them resulted in the amplification of a segment corresponding to the glycoprotein B gene. The resulting NIP (> 96 percent) confirms that the sequence obtained corresponds to type 1 glycoprotein B gene of feline herpesvirus and the efficiency of the method implemented is discussed(AU)

ABSTRACT

ABSTRACT Background: There is little information on herpes zoster from hospital registries in South America. The aim of this study was to describe the epidemiological and clinical aspects of herpes zoster (HZ) in hospitalized patients.' Methods: We searched for hospital-based records during the period from March 2000 to January 2017 in a 700-bed tertiary-care hospital located in southern Brazil. The medical records of all eligible patients were reviewed, and data regarding demographics, medical history, clinical and laboratory characteristics, treatment regimens, and clinical outcomes were collected. Patients were also evaluated for mortality. Results: There were 801 records of herpes zoster according to the proposed criteria. Most patients with HZ presented a cutaneous clinical form of the disease with involvement of a single dermatome (n = 589, 73.5%). Additional clinical characteristics included postherpetic neuralgia (22.1%), ophthalmic HZ (7.6%) and meningoencephalitis (2.7%). Most patients presented immunocompromised conditions (64.9%) including HIV, administration of immunosuppressive agents, and malignant neoplasms. During this period, there were 105 (13.1%) deaths, which were mostly unrelated to HZ. Five deaths were related to HZ meningoencephalitis. Conclusion: The results of this study demonstrate a high burden of HZ disease in a Brazilian tertiary care hospital in the HZ vaccination era. Awareness of the incidence and comorbidity factors associated with HZ in Latin American countries such as Brazil contribute for adoption and implementation of strategies for immunization in this area.

ABSTRACT

PURPOSE: Despite the successful use of tyrosine kinase inhibitors (TKIs) in cancer patients, their effect on herpes zoster development has not been studied. The aim of this study was to evaluate and compare the effects of epidermal growth factor receptor (EGFR) TKI and cytotoxic chemotherapy on the risk of herpes zoster development in non-small cell lung cancer (NSCLC) patients. MATERIALS AND METHODS: We conducted a medical review of all eligible NSCLC patients in Seoul National University hospital between 2002 and 2015. We classified patients based on whether they previously underwent EGFR TKI therapy into either the TKI group or the cytotoxic group. We compared the incidence rates of herpes zoster during TKI therapy and cytotoxic chemotherapy. Additionally, the longitudinal risk of herpes zoster from TKIs was analyzed using the incidence rate ratio (IRR) of the TKI group to the cytotoxic group and the log-rank test of the Kaplan-Meier method. RESULTS: Of the 2,981 NSCLC patients, 54 patients (1.54%) developed herpes zoster. In the TKI group (2,002 patients), the IRR of herpes zoster during TKI therapy compared to that during cytotoxic chemotherapy was 1.05 (95% confidence interval [CI], 0.53 to 2.09). The IRR of the TKI group compared to the cytotoxic group was 1.33 (95% CI, 0.64 to 2.76). The Kaplan-Meier cumulative risk of both groups was not significantly different. CONCLUSION: Our results show that the incidence rate of herpes zoster in the TKI group was not statistically different from the incidence in the cytotoxic group during and after chemotherapy in NSCLC patients.
