ABSTRACT

Justificativas e Objetivos: Câncer de colo de útero é considerado um problema de saúde pública mundial. Seu diagnóstico é realizado através do exame citopatológico (EC) e seu desenvolvimento relacionado à infecção pelo papilomavírus humano (HPV). Este estudo objetiva avaliar o perfil de mulheres atendidas em centros de referência em saúde de Porto Alegre, Rio Grande do Sul, assim como a relação de alterações observadas ao EC com presença do HPV. Métodos: Estudo transversal realizado em mulheres atendidas em unidades básicas de saúde e um ambulatório de referência de hospital público terciário, no período de julho de 2014 a janeiro de 2017. Coletaram-se amostras representativas da endo/ectocérvice para realização do EC e investigadas quanto à presença molecular do HPV. Resultados: Foram analisadas 169 mulheres com idade média entre 31 e 40 anos, das quais 125 (74%) informaram que a sexarca ocorreu na faixa de 15-20 anos e 37,9% relatou ter tido de três a cinco parceiros sexuais. Em relação ao EC, 71 (42%) apresentaram resultado negativo para lesão intraepitelial ou malignidade e 98 (58%) alguma anormalidade de células escamosas: 20 (11,8%) atipias; 22 (13%) lesão intraepitelial escamosa de baixo grau e 56 (32,6%) lesão intraepitelial de alto grau (HSIL). Cinquenta (29,6%) apresentaram positividade para HPV, destas 56,4% foram diagnosticadas com HSIL (p<0,01). Conclusão: Os resultados revelam alta frequência de HPV em amostras com alterações citopatológicas, em mulheres jovens e com grau de exposição ao HPV, reforçando a importância do papel da sua identificação precoce na investigação da carcinogênese cervical.(AU)


Background and Objectives: Cervical cancer is considered a worldwide public health problem. Its diagnosis is made through cytopathological examination and its development related to human papillomavirus (HPV) infection. This study aims to evaluate the profile of women treated at reference health centers in Porto Alegre, Rio Grande do Sul, as well as the relation of changes observed to cytopathological examination with the presence of HPV. Methods: This is a cross-sectional study carried out in women treated at basic health units and a referral clinic of a public tertiary hospital, from July 2014 to January 2017. Representative samples of the endo/ectocervix were collected to perform the cytopathological examination and investigated for the molecular presence of HPV. Results: 169 women with mean age between 31 and 40 years were analyzed, of whom 125 (74%) reported that the onset of sexual activity occurred in the 15-20 years age group, and 37.9% reported having had three to five sexual partners. In relation to cytopathological examination, 71 (42%) had a negative result for intraepithelial lesion or malignancy and 98 (58%) some squamous cell abnormality: 20 (11.8%) atypical; 22 (13%) low-grade squamous intraepithelial lesion and 56 (32.6%) high-grade intraepithelial lesion (HSIL). Fifty (29.6%) were positive for HPV, of which 56.4% were diagnosed with HSIL (p < 0.01). Conclusion: The results reveal a high frequency of HPV in samples with cytopathological changes, in young women and with a degree of exposure to HPV, reinforcing the importance of the role of its early identification in the investigation of cervical carcinogenesis.(AU)


Justificación y objetivos: El cáncer de cuello uterino se considera un problema de salud pública en todo el mundo. Su diagnóstico se realiza mediante el examen citopatológico (EC), y su desarrollo está relacionado con la infección por el virus del papiloma humano (VPH). Este estudio objetivó evaluar el perfil de mujeres atendidas en los centros de referencia en salud de Porto Alegre, Rio Grande do Sul (Brasil), así como la relación de las alteraciones observadas en el EC con la presencia del VPH. Métodos: Estudio transversal realizado en las mujeres atendidas por unidades de atención primaria y por una clínica ambulatoria de referencia del hospital público terciario en la ciudad de Porto Alegre, en el período de julio de 2014 a enero de 2017. Se recolectaron muestras representativas de endo/ectocérvice para realizar la CE, las cuales se clasificaron según el sistema Bethesda y se investigaron la presencia molecular del VPH. Resultados: Analizamos 169 mujeres con promedio de edad entre 31 y 40 años, de las cuales 125 (74%) informaron que el sexarche ocurrió en el rango de 15-20 años. La mayoría (37,9%) informó haber tenido de 3 a 5 parejas sexuales; y el 37,3% estaban usando anticonceptivos orales. Con respecto a la EC, 71 (42%) se clasificaron como negativos para lesión intraepitelial o malignidad; y el 98 (58%) tenían alguna anormalidad de células escamosas: 20 (11,8%) de atipias; 22 (13,0%) lesión intraepitelial escamosa de bajo grado y 56 (32,6%) lesión intraepitelial de alto grado (HSIL). La frecuencia de positividad del VPH encontrada fue de 50 (29,6%), de estas un 56,4% fueron diagnosticadas con HSIL (p<0,01). Conclusiones: Estos resultados revelan una alta frecuencia de VPH en muestras con alteraciones citopatológicas presentes en mujeres jóvenes con cierto grado de exposición al VPH, lo que refuerza la importancia de identificarse tempranamente en el análisis de la carcinogénesis cervical.(AU)

ABSTRACT

The influence of different infectious agents and their association with human papillomavirus (HPV) in cervical carcinogenesis have not been completely elucidated. This study describes the association between cytological changes in cervical epithelium and the detection of the most relevant aetiological agents of sexually transmitted diseases. Samples collected from 169 patients were evaluated by conventional cytology followed by molecular analysis to detect HPV DNA, Chlamydia trachomatis, herpes simplex virus 1 and 2,Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, andTreponema pallidum, besides genotyping for most common high-risk HPV. An association between cytological lesions and different behavioural habits such as smoking and sedentariness was observed. Intraepithelial lesions were also associated with HPV and C. trachomatis detection. An association was also found between both simple and multiple genotype infection and cytological changes. The investigation of HPV and C. trachomatisproved its importance and may be considered in the future for including in screening programs, since these factors are linked to the early diagnosis of patients with precursor lesions of cervical cancer.

ABSTRACT

Objetivo: Caracterizar os candidatos quanto ao gênero e analisar a prevalência dos critérios de inaptidão adotados às doações de sangue, realizadas no Banco de Sangue Santa Maria, em Santa Maria, RS. Métodos: Dados retrospectivos arquivados foram avaliados, analisando-se os critérios de exclusão na triagem clínica e sorológica, no período de janeiro de 2005 até dezembro de 2010. Foram analisados 20.264 doadores. O estudo foi aprovado pelo Comitê de Ética e Pesquisa da Universidade Federal do Rio Grande do Sul-UFRGS, sob número de protocolo 18147. Resultados: Novecentos e setenta e seis (5%) candidatos foram considerados inaptos pela triagem clínica e 19.288 (95%) foram considerados aptos para prosseguirem com os testes laboratoriais. Dos doadores aptos, 941 (5%) foram excluídos na triagem sorológica, totalizando 18.347 bolsas de sangue disponíveis para uso. Predominaram os doadores do sexo masculino (62%) e a principal causa de exclusão, na triagem clínica, foi hipertensão (0,7%). Para a triagem sorológica, a principal causa de exclusão foi a Doença de Chagas (1,5%). Conclusão: Ressaltou-se a importância da triagem clínica, tendo em vista que ela excluiu 5% dos candidatos à doação e a relevância da triagem sorológica ser feita corretamente, evitando que resultados falso-negativos sejam liberados.


Objective: Characterize donors by gender and analyze theprevalence of the inability criteria of donations made at the SantaMaria Blood Bank, located at Santa Maria, Brazil. Methods: First,we searched historical data for exclusion criteria used in clinicaland serological screenings during the period from January, 2005 toJuly, 2010. We evaluated 20,264 blood donors' data for this study.The Ethical Committee of Rio Grande do Sul Federal UniversityUFRGSapproved this study under the protocol number 18147.Results: Nine hundred and seventy-six (5%) candidates wereconsidered unfit by the clinical screening and 19,288 (95%) wereconsidered fit. From the resulting fit population of the clinicalscreening, 941 (5%) were excluded from donating by the serologicalscreening, totaling 18.347 blood donations fit for use. The resultsshows that majority of the donors were male (62%) and the leadingcause of exclusion from donating in the clinical screening washypertension (0.7%). As for the serological screening, the leadingcause for exclusion was Chagas disease (1.5%). Conclusion: Thestudy stress the importance of the clinical screening process, giventhat it excluded 5% of blood donations, which were unfit for use. Wealso notice the relevance of a correctly done serological screening,thus avoiding that false-negative results are released.

ABSTRACT

INTRODUCTION: Laboratory-based surveillance is an important component in the control of vancomycin resistant enterococci (VRE). METHODS: The study aimed to evaluate real-time polymerase chain reaction (RT-PCR) (genes vanA-vanB) for VRE detection on 115 swabs from patients included in a surveillance program. RESULTS: Sensitivity of RT-PCR was similar to primary culture (75 percent and 79.5 percent, respectively) when compared to broth enriched culture, whereas specificity was 83.1 percent. CONCLUSIONS: RT-PCR provides same day results, however it showed low sensitivity for VRE detection.

ABSTRACT

Introdução: o câncer cervical tem sido apontado como a segunda neoplasia mais comum entre as mulheres, sendo muitas vezes associado a agentes infecciosos (AI) relacionados a doenças sexualmente transmissíveis (DST) ou oportunistas do trato genitourinário. Objetivo: avaliar diferentes variáveis epidemiológicas, assim como a prevalência dos AI encontrados no exame citológico preventivo e correlacioná-las às alterações citológicas cervicais benignas e malignas. Métodos: análise retrospectiva dos laudos de exames citológicos emitidos entre os anos de 2004 e 2009 de pacientes atendidas em 33 Unidades Básicas de Saúde de Porto Alegre. Foram selecionados 850 laudos de diferentes pacientes e analisadas as variáveis: faixa etária, grau de instrução,AI e alterações celulares. Resultados: cerca de 70% das pacientes situam-se na faixa etária entre 14 e 45 anos, predominando o 1o grau incompleto (38,4%).O agente infeccioso que apresentou maior prevalência foi a Gardnerella vaginalis, com 15,6%, seguida de Candida sp. (2,3%) e Trichomonas vaginalis(2,2%). Dentre as alterações celulares cervicais benignas, a que apresentou maior prevalência foi o epitélio inflamatório (67%), sendo a maioria observada na faixa etária mais jovem. Obteve-se correlação estatisticamente significativa entre as alterações celulares cervicais benignas com os agentes infecciosose com a idade, sendo que dos 275 casos de inflamação, 161 (58,5%) apresentavam também algum AI. Em relação às alterações celulares malignas, poucos casos foram detectados, não sendo possível obter qualquer correlação. Conclusão: os resultados observados em nosso estudo sugerem que há correlação dealterações cérvico-vaginais benignas com casos de infecções microbianas concomitantes ou pregressas nas pacientes avaliadas neste estudo.


Introduction: cervical cancer has been considered the second most common malignancy among women, and is often associated with infectious agents (AI) related to sexually transmitted diseases (STDs) or opportunistic of genitourinary tract. Objective: to evaluate the epidemiological variables and correlate them with cytological benign and malignant cervical changes, as well as the prevalence of AI found in cytology preventive exam. Methods: retrospective analysis of cytological reports issued between 2004 and 2009 of patients treated in 33 Basic Health Care Units in Porto Alegre. A total of 850 reports were selected from different patients and the following variables were analyzed: age, education, AI and cellular changes. Results: approximately 70% of women are at the age between 14 and 45 years old, mainly with incomplete primary school (38.4%). The infectious agent that had the highest prevalence wasGardnerella vaginalis with 15.6% followed by Candida sp. (2.3%) and Trichomonas vaginalis (2.2%). Among the benign cervical cell changes with the highest prevalence was inflammatory epithelium (67%), mostly observed in the youngest age group. A statistically significant correlation between the benign cervical cell changes with infectious agents and with age was obtained, and of 275 cases of inflammation, 161 (58.5%) had also some AI. Regarding tomalignant cell changes, few cases were detected; it is not possible to obtain any correlation. Conclusion: the results observed in this study suggest that there is a correlation of cytological changes in cervical-vaginal benign cases with previous or concomitant microbial infections in women evaluated in this study.

ABSTRACT

The introduction of newer molecular methods has led to the discovery of new respiratory viruses, such as human metapneumovirus (hMPV) and human bocavirus (hBoV), in respiratory tract specimens. We have studied the occurrence of hMPV and hBoV in the Porto Alegre (PA) metropolitan area, one of the southernmost cities of Brazil, evaluating children with suspected lower respiratory tract infection from May 2007-June 2008. A real-time polymerase chain reaction method was used for amplification and detection of hMPV and hBoV and to evaluate coinfections with respiratory syncytial virus (RSV), influenza A and B, parainfluenza 1, 2 and 3, human rhinovirus and human adenovirus. Of the 455 nasopharyngeal aspirates tested, hMPV was detected in 14.5 percent of samples and hBoV in 13.2 percent. A unique causative viral agent was identified in 46.2 percent samples and the coinfection rate was 43.7 percent. For hBoV, 98.3 percent of all positive samples were from patients with mixed infections. Similarly, 84.8 percent of all hMPV-positive results were also observed in mixed infections. Both hBoV and hMPV usually appeared with RSV. In summary, this is the first confirmation that hMPV and hBoV circulate in PA; this provides evidence of frequent involvement of both viruses in children with clinical signs of acute viral respiratory tract infection, although they mainly appeared as coinfection agents.

ABSTRACT

INTRODUÇÃO: O norovírus foi recentemente identificado como o principal causador de surtos de gastroenterite aguda de origem não bacteriana em todo o mundo e está envolvido em episódios de origem alimentar. Neste estudo, foram avaliados pacientes com sintomas de gastroenterite aguda pelo período de um ano, a fim de se avaliar duas metodologias na identificação do NoV - a reação em cadeia por polimerase convencional e em tempo real -, incidência, sazonalidade e genótipo predominante. MÉTODOS: Após a extração do RNA, 50 amostras foram analisadas pela metodologia de PCR convencional e 365 amostras foram analisadas pela metodologia de PCR em tempo real. Todas as amostras que apresentaram resultado positivo pelas duas metodologias ou discordante foram sequenciadas, ao todo, 13 amostras foram sequenciadas. RESULTADOS: Das 50 amostras testadas pelas duas metodologias, 7 apresentaram resultado positivo pelo método convencional e 15 pelo método da PCR em tempo real. Do total de 365 amostras testadas pela metodologia de PCR, em tempo real, 48 foram positivas. Em relação às amostras sequenciadas, todas mostraram ser NoV do genogrupo II. Em relação à distribuição da incidência de amostras, positivas para NoV, ao longo do ano, pôde ser observada uma frequência de casos positivos maior na primavera, chegando a 29,7 por cento em novembro. CONCLUSÕES: Observamos que o PCR em tempo real é o método mais sensível para a identificação do Nov, que a incidência do NoV é de 13,2 por cento e o genogrupo II prevalece na população avaliada, sendo a primavera o período de maior taxa de infecção.


INTRODUCTION: Norovírus was recently identified as the main cause of outbreaks of acute gastroenteritis of non-bacterial origin worldwide and it is involved in episodes of foodborne origin. In this study, patients with symptoms of acute gastroenteritis were evaluated over a one-year period, in order to evaluate two methods for identifying norovírus (real-time and conventional polymerase chain reaction), along with its incidence, seasonality and predominant genotype. METHODS: After RNA extraction, 50 samples were analyzed using conventional PCR and 365 were analyzed using real-time PCR. All the samples that presented positive results using both methods or discordant results were sequenced. In all, 13 samples were sequenced. RESULTS: Out of the 50 samples tested using both methods, seven presented a positive result from the conventional method and 15 from real-time PCR. Out of the total of 365 samples tested using real-time PCR, 48 were positive. All of the sequenced samples were shown to present norovírus of genogroup II. Regarding the distribution of norovírus-positive sample incidence over the course of the year, higher frequency of positive cases was observed during the southern hemisphere spring, reaching 29.7 percent in November. CONCLUSIONS: We observed that real-time PCR was more sensitive for identifying norovírus. The incidence of norovírus was 13.2 percent and genogroup II predominated among the population evaluated, with the greatest infection rate in the southern hemisphere spring.

ABSTRACT

INTRODUÇÃO E OBJETIVOS: São conhecidos mais de 100 tipos de papilomavírus humano (HPV), dos quais 30 têm sido reportados em infecções anogenitais. A infecção tem importância clínica, pois alguns tipos virais estão associados a lesões que podem progredir para o câncer cervical. Sabe-se que os métodos moleculares são muito importantes para o diagnóstico dessa infecção. O objetivo do estudo é comparar a detecção de HPV de alto risco pelo método de captura híbrida 2 (CH2) com a detecção do vírus pela reação em cadeia da polimerase convencional (PCRc) e em tempo real (PCR-TR). METODOLOGIA: Foram analisadas 56 amostras ectocervicais por CH2 e, após, por PCRc e PCR-TR. RESULTADOS: Ambas, PCRc e PCR-TR, apresentaram alta concordância entre si (95,1 por cento), enquanto a comparação entre as PCRs e a CH2 mostrou concordância razoável entre os resultados (PCRc = 90,2 por cento e PCR-TR = 87,8 por cento). DISCUSSÃO E CONCLUSÃO: A CH é aceita para a detecção do HPV, entretanto pode ser menos sensível em comparação com as técnicas de PCR. A PCR-TR tem a vantagem sobre a PCRc em termos de velocidade, sendo também um pouco mais sensível. Devido à alta sensibilidade e à rapidez, os métodos de PCR poderiam ser usados para a triagem de HPV em amostras ectocervicais.


INTRODUCTION AND OBJECTIVE: More than 100 types of human papillomaviruses (HPV) are known, of which 30 have been reported in anogenital infections. The infection has clinical importance, inasmuch as some viral types are associated with lesions that can progress to cervical cancer. Molecular methods are considered an important tool for the diagnosis of this infection. The objective of this study was to compare the detection of high risk HPV using hybrid capture 2 with HPV detection by conventional and real time PCR. METHODOLOGY: 56 ectocervical samples were analyzed by hybrid capture and after that by conventional and real time PCR. RESULTS: Both PCR and RT-PCR showed a high degree of correlation (95.1 percent), whereas the comparison between PCR and HC2 showed a fair correlation (90.2 percent and 87.8 percent for PCR and RT-PCR, respectively). DISCUSSION AND CONCLUSIONS: HC is widely accepted for the detection of HPV, however, it may lack sensitivity in comparison with PCR techniques. RT-PCR has further advantages over the conventional PCR in terms of speed as well as it is slightly more sensitive. Due to their high sensitivity and fast response, PCR methods could be used as a screening method for HPV detection in ectocervical samples.

ABSTRACT

Corynebacterium species have often been considered normal skin flora or contaminants; however, in recent years they have been increasingly implicated in serious infections. Moreover, many new species have been discovered and old species renamed, especially after molecular biology techniques were introduced. Corynebacterium mucifaciens is mainly isolated from blood and from other normally-sterile body fluids; it forms slightly yellow, mucoid colonies on blood agar. We report a fatal case of bacteremia due to an atypical strain of C. mucifaciens. This strain had atypical colony morphology; analysis of the 16S rRNA gene was used to define the species.
