ABSTRACT

Abstract Worldwide, conventional agriculture makes extensive use of pesticides. Although the effects of herbicides are relatively well known in terms of environmental impacts on non-target organisms, there is very little scientific evidence regarding the impacts of herbicide residues on aquatic arthropods from tropical conservation areas. This study evaluates for the first time the toxicity of the herbicides ametryn, atrazine, and clomazone on the aquatic insect Limnocoris submontandoni (Hemiptera: Naucoridae). The lethal concentration (LC50) of herbicides was evaluated for these insects, as well as the effect of the herbicides on the insects' tissues and testicles. The estimated LC50 was 1012.41, 192.42, and 46.09 mg/L for clomazone, atrazine, and ametryn, respectively. Spermatocyte and spermatid changes were observed under the effect of atrazine, and effects on spermatogenesis were observed for some concentrations of clomazone, with apparent recovery after a short time. Our results provide useful information on the effects of herbicide residues in aquatic systems. This information can help minimize the risk of long-term reproductive effects in non-target species that have been previously overlooked in ecotoxicology studies.


Resumo Em todo o mundo, a agricultura convencional faz uso extensivo de pesticidas. Embora os efeitos dos herbicidas sejam relativamente bem conhecidos em termos de impactos ambientais em organismos não-alvo, há pouca evidência científica sobre os impactos de resíduos de herbicidas em artrópodes aquáticos de áreas de conservação tropicais. Este estudo avalia pela primeira vez a toxicidade dos herbicidas ametryn, atrazine e clomazone sobre o inseto aquático Limnocoris submontandoni (Hemiptera: Naucoridae). A concentração letal (LC50) de herbicidas foi avaliada para esses insetos, bem como o efeito dos herbicidas nos tecidos e testículos dos insetos. A LC50 estimada foi de 1012,41, 192,42 e 46,09 mg/L para clomazone, atrazine e ametryn, respectivamente. Alterações nos espermatócitos e espermátides foram observadas sob o efeito de atrazine, e efeitos na espermatogênese foram observados para algumas concentrações de clomazone, com aparente recuperação após um curto período de tempo. Nossos resultados fornecem informações úteis sobre os efeitos de resíduos de herbicidas em sistemas aquáticos. Essas informações podem ajudar a minimizar o risco de efeitos reprodutivos de longo prazo em espécies não-alvo que foram negligenciadas anteriormente em estudos de ecotoxicologia.

ABSTRACT

Abstract Urinary tract infections are responsible for most human infections, these are caused by bacteria, fungi, protozoa and associated microorganisms. The goal of this study was to determine the rate of vaginal infection-causing agents in routine cytological exams and also to evaluate the characteristics of positive tested Pap smears. A retrospective documental with descriptive aspect research was performed in a Clinical Pathology laboratory from Maceió-AL. The results of the Pap smears exams for Trichomonas vaginalis, Gardnerella vaginalis, Candida spp and HPV were arranged in a database as well as other data such as bacterial, protozoan, fungal and viral coinfections. The sample was composed by 18.645 women who have undergone Pap smear exams from 2013 to 2017. Of these analyzed exams, 27.4% in 2013, 10.9% in 2014, 10.6% in 2015, 15.2% in 2016 and 13.67% in 2017 were within normal range, however more than half of these exams presented some infections caused by unspecific or microbiological agents. By analyzing all the reports, 4.073 (21.84%) presented inflammations caused by some species of infectious agent with the following rate order: G. vaginalis and T. vaginalis. Furthermore, it was possible to confirm high rates of coinfection by and Candida spp. The rate of genital infections in this study highlights that there is a public health matter that must be controlled, which points a greater need for monitoring, guidance and actions towards greater awareness in order to prevent these problems.


Resumo Infecções do trato urinário são responsáveis pela maior parte das infecções humanas, sendo causadas por bactérias, fungos, protozoários, e por microrganismos associados. O objetivo deste trabalho foi determinar a frequência de agentes causadores de infecções vaginais nos exames citológicos de rotina, bem como avaliar as características dos esfregaços positivos. Foi realizada uma pesquisa do tipo documental retrospectiva de aspecto descritivo, com abordagem quantitativa, em um Laboratório de Patologia Clínica de Maceió-AL. Nesse sentido, os resultados dos exames colpocitológicos para Trichomonas vaginalis, Gardnerella vaginalis, Candida spp e HPV foram organizados em um banco de dados, contendo os resultados para estes agentes, bem como a coinfecção bacteriana, protozoária, fúngica e viral. A amostra foi composta por 18.645 mulheres que realizaram exame colpocitológico, no período de 2013 a 2017. Destes exames analisados 27,4% em 2013, 10,9% em 2014, 10,6% em 2015, 15,2% em 2016 e 13,67% em 2017, estavam dentro do limite da normalidade, porém mais que a metade desses exames analisados apresentou algumas infecções causadas por agentes inespecíficos ou microbiológicos. Do total de laudos analisados, 4.073 (21,84%), apresentaram inflamações causadas por algum tipo de agente infeccioso, com a seguinte ordem de frequência: G. vaginalis, e T. vaginalis. Além disto, foi possível confirmar a elevada frequência de coinfecção entre G. vaginalis e Candida spp. Os índices de infecções genitais nesse trabalho mostram que há um problema de saúde pública que deve ser controlado, apontando uma necessidade maior de acompanhamento, orientações e de ações para uma maior conscientização para prevenir esses problemas.

ABSTRACT

Nevo epidérmico verrucoso inflamatório linear e diagnóstico diferencial com a psoríase linear: a respeito de um caso RELATO DE CASOMaria Isabel Muniz Zemero1, Maria Amélia Lopes dos Santos1, Alena Margareth Darwich Mendes1, Carla Andrea Avelar Pires1,O nevo epidérmico verrucoso inflamatório linear (NEVIL) é uma variedade clínica rara de nevo epidérmico verrucoso, que se manifesta no início da infância, como lesões inflamatórias de superfície ceratósica, que coalescem e se distribuem em faixa, acompanhando as linhas de Blaschko. Faz diagnóstico diferencial com a psoríase linear, sendo difícil a diferenciação, dado os aspectos clínicos e histopatológicos comuns aos dois, enfantizando-se a necessidade de conhecer as características específicas de cada um. O objetivo deste relato é demonstrar uma afecção relativamente rara, descrita em uma menina de 5 anos, evoluindo desde os primeiros dias de vida com placas papuloceratósicas dispostas linearmente, acompanhadas de sinais inflamatórios e áreas erosadas ocupando grandes lábios, períneo e face interna e superior da coxa esquerda. Também pápulas e placas ceratósicas na região cervical posterior e borda lateral externa da planta do pé esquerdo, ascendendo ao longo da região posterior deste membro. Os critérios clínicos e histopatológicos corroboram o diagnóstico de NEVIL na diferenciação com a psoríase linear, ressaltando a importância do estabelecimento de critérios/ ferramentas que auxiliem na diferenciação destas duas dermatoses visando agilizar o diagnóstico, otimizar o tratamento e minimizar o desconforto para esses pacientes. O acompanhamento a longo prazo dos portadores é sugerido pela possibilidade ainda que mínima de malignização do NEVIL. (AU)


Inflammatory linear verrucous epidermal nevus and differential diagnosis with linear psoriasis: about a caseCASE REPORTMaria Isabel Muniz Zemero1, Maria Amélia Lopes dos Santos1, Alena Margareth Darwich Mendes1, Carla Andrea Avelar Pires1,Inflammatory Linear Verrucous Epidermal Nevus (ILVEN) is a rare clinical variety of verrucous epidermal nevus that manifests in early childhood as inflammatory lesions of keratosis surface, which coalesce and spread in band, following Blaschko lines. It makes a differential diagnosis with Linear Psoriasis; it is difficult to differentiate them given the clinical and histopathological aspects common to both, emphasizing the need to know the specific characteristics of each. The purpose of this report is to demonstrate a relatively rare affection, expressed in a 5-year-old girl, evolving from the first days of life with papulokeratosic plaques arranged linearly, followed by inflammatory signs and eroded areas, placed linearly, overtaking labia majora, perineum, the inner and upper face of the left thigh. Also, the patient showed keratotic papules and plaques in the posterior cervical region and external lateral border of the left foot plant, ascending along the posterior region of this limb. The clinical and histopathological criteria corroborate the diagnosis of ILVEN in differentiation with linear psoriasis, emphasizing the importance of establishing criteria/instruments to assist in distinguishing these two dermatoses in order to expedite the diagnosis, to optimize the treatment and minimize patients' discomfort. Long-term follow-up of patients with this disease is suggested due to the possibility, albeit minimal, of ILVEN malignancy. (AU)

ABSTRACT

The species of Pugilina cochlidium (Linnaeus, 1758) and P. erecta (Vermeij & Raben, 2009) has been studied in the present study. The female can be differentiated from the male by the absence of the cephalic penis and a complicated genital aparatus visible through the mantle skirt in both the sexes. In other aspects of the external features of female are quite to males. In both species the digestive system was similar with few differences in structure between each other. It consists of buccal mass, proboscis, salivary glands, accessory salivary glands, oesophagus, stomach, intestine, rectum and anus. The nervous system in both P. cochlidium and P. erecta is constituted by six ganglia which forms the circumoesophgeal ganglionic ring. Among the neogastropods there is a similarity in the organization of the reproductive systems. The female reproductive system is more complicated than that of male. The sexes are separated in these two species. The gross morphology of the reproductive system of P. cochlidium and P. erecta was almost similar. The present study aims to describe the digestive system, nervous system and reproductive system of two gastropods species P. cochlidium and P. erecta.


As espécies de Pugilina cochlidium (Linnaeus, 1758) e P. erecta (Vermeij & Raben, 2009) foram tomadas no presente estudo. A fêmea pode ser diferenciada do macho pela ausência do pênis cefálico e um complicado complexo genital visível através da saia do manto em ambos os sexos. Em outros aspectos das características externas da fêmea são bastante semelhantes aos dos machos. Em ambas as espécies, o sistema digestivo era semelhante, com poucas diferenças de estrutura entre si. Consiste em massa bucal, probóscide, glândulas salivares, glândulas salivares acessórias, esôfago, estômago, intestino, reto e ânus. O sistema nervoso em P. cochlidium e P. erecta é constituído por seis gânglios que formam um anel ganglionar circunoesofágico. Entre os neogastrópodes, há uma semelhança na organização dos sistemas reprodutivos. O sistema reprodutivo feminino é mais complicado que o masculino. Os sexos são separados nessas duas espécies. A morfologia macroscópica do sistema reprodutivo de P. cochlidium e P. erecta foi quase similar. O presente estudo tem como objetivo descrever o sistema digestivo, sistema nervoso e sistema reprodutivo de duas espécies, P. cochlidium e P. erecta.

ABSTRACT

Resumo A intersexualidade ainda é considerada uma deformidade patológica, bem como é alvo de intervenções cirúrgicas corretivas que visam enquadrar pessoas intersexos nos padrões binários de sexo, gênero e orientação sexual socialmente aceitos. Desse modo, o objetivo deste estudo foi analisar os sentidos produzidos por intersexos às intervenções cirúrgicas de designação sexual e suas consequências, ainda que não tenham realizado procedimentos cirúrgicos. Trata-se de uma pesquisa qualitativa de corte transversal cujos dados foram coletados por meio de um questionário online para intersexos e interessados de uma rede social-virtual. Oito intersexos participaram da pesquisa e as informações obtidas foram organizadas a partir de uma análise de conteúdo temática em quatro categorias: a) violação de direitos sobre a autodeterminação de sexo-gênero; b) tentativas de invisibilização da experiência de intersexos; c) despreparo da equipe de saúde de referência; e d) centralidade dos ativismos intersexos. Os resultados destacam que: as cirurgias são realizadas sem o consentimento dos intersexos e impactam sua subjetividade e relações sociais; há a reprodução de expectativas pelo intersexo, sua família e pelos profissionais da saúde em torno dos binarismos de sexo-gênero; há a necessidade dos ativismos políticos responderem às demandas dessa população. As constituições de sexo e de gênero ilustradas pelas cirurgias de designação sexual são produtos culturais pautados num sistema normativo binário e cisheterossexual que reproduz e perpetua discriminações, estigmas e violências. Assim, é papel da Psicologia contribuir para a compreensão dessa temática e para a incrementação de políticas públicas na saúde, educação e em assistência social para essa população.(AU)


Abstract Intersexuality is still considered a pathological deformity, requiring corrective surgical interventions to fit intersex persons into socially determined binary patterns of sex, gender, and sexual orientation. Thus, this study aimed to analyze the meanings attributed to surgical interventions for sex reassignment and their consequences according to intersex persons who underwent or not the procedure. This qualitative cross-sectional survey was conducted with data collected by means of an online questionnaire for intersex and interested people, made available in a social network. Eight intersexes participated in the survey. The collected data underwent thematic content analysis and were organized into four categories: a) violations to sex/gender self-determination rights; b) attempts to invisibilize the experiences of intersex persons; c) unpreparedness of healthcare team; and d) intersexes activism. The results highlight the performance of these surgeries without intersex persons' consent, as well as their impacts on subjectivity and social relations; the reproduction of expectations around sex/gender binarism on the part of these individuals themselves, their families, and health professionals; and the need for political activism to respond to their demands. The constitutions of sex and gender illustrated by sexual designation surgeries are cultural products based on a binary and cishetero-normative system that reproduces discrimination, stigma, and violence. In this scenario, Psychology plays a key role in contributing to the understanding of this issue, advancing public policies aimed at promoting health, education, and social assistance to this population.(AU)


Resumen La intersexualidad todavía se considera como una deformación patológica, así como está sujeta a intervenciones quirúrgicas correctivas que tienen por objeto encajar a los individuos intersexuales en los patrones binarios de sexo, género y orientación sexual. El objetivo de este estudio fue analizar los significados que tienen para los intersexuales las intervenciones quirúrgicas de reasignación sexual y sus consecuencias, incluso para aquellos que no las habían realizado. Se trata de una investigación cualitativa, transversal, realizada por medio de un cuestionario destinado a un grupo de intersexuales e interesados en una red social en internet. Ocho intersexuales participaron, y los dados se organizaron a partir del análisis de contenido temático en categorías: a) violación de los derechos sobre la autodeterminación de sexo-género; b) intentos de hacer invisible la experiencia intersexual; c) falta de preparación del equipo sanitario; y d) centralidad del activismo intersexual. Los principales resultados apuntaron la realización de estas cirugías sin el consentimiento de los intersexuales y que estas tienen repercusiones negativas en la subjetividad y las relaciones sociales de ellos; la reproducción de las expectativas personales, familiares y de los profesionales de la salud en torno a los binarismos de género; la necesidad de un activismo colectivo para responder a las demandas de esta población. Las constituciones de sexo y género ilustradas por las cirugías de reasignación sexual de intersexuales son productos culturales con base en un sistema normativo binario y cisheterosexual que reproduce discriminación, estigmas y violencia. Es el papel de la Psicología contribuir a la comprensión de esta cuestión para animar las políticas públicas de salud, educación y asistencia social a esta población.(AU)

ABSTRACT

Abstract A 31-year-old male patient developed an ulcer on the glans penis that evolved for three months without healing. We diagnosed it as leishmaniasis using polymerase chain reaction. No immunosuppression or associated diseases were observed. The patient was treated with meglumine antimoniate that cured the lesion in a month post-treatment. Here, we report this case of cutaneous leishmaniasis lesion at the unusual location of glans penis in an immunocompetent individual. The lesion likely developed due to the bite of a vector, highlighting the need for considering cutaneous leishmaniasis among differential diagnosis of sexually transmitted diseases in areas endemic for leishmaniasis.

ABSTRACT

Abstract Leishmaniasis is a tropical infectious disease caused by Leishmania spp. protozoa and is transmitted by insects from the Phlebotominae subfamily. It can manifest as cutaneous leishmaniasis, a painless ulcer that can develop into a more serious systemic affliction as the protozoa spreads lymphatically or hematogenously, depending on the host's immunity. In this case series, the authors present a rare form of genital mucocutaneous leishmaniasis, with consideration of epidemiologic characteristics, clinical presentation, differential diagnosis, and treatments offered.

ABSTRACT

Introduction: HPV infection causes cancer at several anatomical sites. However, the infection's natural history in non-cervical sites is understudied. Objective: To evaluate oral and anogenital HPV infections, correlating HPV prevalence rates and genotypes with site of infection and risk factors. Methods: In the present study, 351 samples from oral, genital, and anal sites of 117 patients were investigated by using PCR MY09/11 detection, followed by genotyping with RFLP. Results: HPV DNA prevalence was 89.7% (105/117) in genital lesions, 53.8% (63/117) in oral samples, and 58.9% (69/117) in anal samples. Regarding the risk factors associated with HPV in genital lesions, statistically significant rates for oral (p=0.039) and anal sex practices (p=0.0000012) were found. For oral samples, a relevant correlation concerning oral contraceptive use (p=0.039), tobacco smoking (p=0.036), and alcohol use (p=0.0075) were observed; whereas in anal samples, higher risk for HPV infection in patients who reported non-exclusive sexual partners (p=0.013) were found. The presence of viral DNA in all the three sites concurrently was observed in 36.8% of the cases (43/117). Among them, 18% (21/117) presented concordant HPV genotypes, diverging from the literature, and thus corroborating that there is still much to learn about HPV natural history, since different biological behaviors are expected within different populations. Differences in anatomy and physiology of the studied sites can determine different prevalence rates of infection by diverse genotypes. Conclusion: Due to the high prevalence of HPV DNA in extragenital sites, further studies are required to define aspects of HPV natural history among different human anatomical sites.


Introdução: As infecções causadas pelos papilomavírus humanos (HPV) são responsáveis pelo desenvolvimento de cânceres em diversos sítios anatômicos humanos. Entretanto, a história natural da infecção em sítios que não a cérvice uterina não é muito clara. Objetivo: Avaliar infecções orais, genitais e anais por HPV, correlacionando taxas de prevalência do vírus e seus genótipos aos sítios de infecção e a fatores de risco sócio-demográficos. Métodos: Em nosso estudo, investigamos 351 amostras coletadas dos sítios oral, genital e anal de 117 pacientes, por meio da técnica de PCR MY09/11, seguida de genotipagem por RFLP. Todos os pacientes apresentavam lesões genitais benignas. Resultados: A prevalência do HPV foi de 89,7% (105/117) nas lesões genitais, 53,8% (63/117) nas amostras orais e 58,9% (69/117) nas amostras anais. Em relação aos fatores de risco associados à infecção genital, encontramos diferenças estatísticas significativas para prática de sexo oral (p=0,039) e sexo anal (p=0,0000012). Já para as amostras orais, observamos importante correlação entre infecção e uso de contraceptivo oral (p=0,039), tabagismo (p=0,036) e uso de álcool (p=0,0075) enquanto nas amostras anais, alto risco de infecção pelo HPV foi associado a pacientes relatando parceiros sexuais não exclusivos (p=0,013). A presença do DNA viral simultaneamente nos três sítios estudados foi observada em 36,8% dos casos (43/117). Desses, 18% (21/117) apresentaram genótipos concordantes, diferindo da literatura, na qual há grande disparidade de descrições. Conclusão: Há a necessidade de novos estudos a fim de esclarecer a história natural do HPV em sítios extragenitais em diferentes populações, avaliando características anatômicas e fisiológicas com o intuito de esclarecer diferentes taxas de infecção por genótipos do HPV e diferentes processos de doença.

ABSTRACT

A pele de tilápia possui microbiota não infecciosa e estrutura morfológica semelhante à pele humana. Estudos clínicos fase II, ainda não publicados, mostraram resultados promissores na sua utilização para tratamento de queimaduras. Nos protocolos destes estudos, pacientes com lesões em áreas de dobras de pele, como genitais e região inguinal, foram excluídos, pois achava-se que o biomaterial não aderiria apropriadamente, resultando em um grau de cicatrização inferior. Relato de caso de paciente do sexo feminino, 18 anos, sem comorbidades, com queimaduras de segundo grau profundo em abdômen, região inguinal, parte da genitália e metade superior de ambas as coxas, envolvendo 13,5% da área total da superfície corporal. A pele de tilápia foi aplicada nas lesões levando a uma reepitelização completa com 16 dias de tratamento. Não foram observados efeitos colaterais. A pele de tilápia traz, portanto, a promessa de um produto inovador, de fácil aplicação e alta disponibilidade, que pode se tornar a primeira pele animal nacionalmente estudada e registrada pela Agência Nacional de Vigilância Sanitária, para uso no tratamento de queimaduras. Este relato de caso contribui para reduzir as limitações em relação às áreas anatômicas apropriadas para a aplicação da pele de tilápia, uma vez que, mesmo com a necessidade de reposição de pele, foram obtidos bons resultados com aplicação na genitália e região inguinal.


Tilapia skin has a non-infectious microbiota and a morphological structure similar to human skin. Phase II clinical studies, not yet published, have shown promising results in their use for the treatment of burns. In the protocols of these studies, patients with lesions in areas of skin folds, such as genitals and inguinal regions, were excluded, as it was thought that the biomaterial would not adhere properly, resulting in a lower degree of healing. Case report of a female patient, 18 years old, without comorbidities, with deep second-degree burns in the abdomen, inguinal region, part of the genitalia and upper half of both thighs, involving 13.5% of the total body surface area. Tilapia skin was applied to the lesions leading to a complete re-epithelialization with 16 days of treatment. No side effects were observed. Tilapia skin, therefore, brings the promise of an innovative product, easy to apply, and highly available, which can become the first animal skin nationally studied and registered by the Agência Nacional de Vigilância Sanitária, for use in the treatment of burns. This case report contributes to reduce the limitations concerning the anatomical areas appropriate for the application of tilapia skin, since, even with the need for skin replacement, good results were obtained with application to the genitalia and inguinal region.

ABSTRACT

An adult, female, 31kg body weight, free range Myrmecophaga tridactyla was referred for medical consultation due to apathy, dehydration, intense flatulence and fetid stools. The animal was submitted to chemical restraint and physical examination, blood count, fecal analysis, and vaginal cytology and abdominal ultrasonography were performed. Good nutritional status and clinical variables within the normal range were observed at physical examination. At vaginal cytology leukocytes, spermatozoa and a large proportion of cornified cells (superficial) were observed, indicating estrus and recent copula. At ultrasound examination it was possible to locate, identify, evaluate and measure the ovaries and the uterine structures, cervix, body, lumen, myometrium and endometrium, a fact never reported in the literature for this species. These data can be used as reference for clinical evaluation of the reproductive tract in Myrmecophaga tridactyla females considered vulnerable species, for the diagnosis of reproductive pathologies, biotechnologies application or estrous cycle evaluation.(AU)


Uma fêmea, com 31kg de peso corporal, de Myrmecophaga tridactyla, de vida livre, foi apresentada para consulta médica em razão de apatia, desidratação, flatulência intensa e fezes fétidas. O animal foi submetido à contenção química e foram realizados exame físico, hemograma, análise fecal, citologia vaginal e ultrassonografia abdominal. Ao exame físico, foi determinado bom estado nutricional e variáveis clínicas dentro da faixa de normalidade. Na citologia vaginal, foram observados leucócitos, espermatozoides e uma grande proporção de células cornificadas (superficiais), indicando estro e cópula recente. No exame ultrassonográfico, foi possível localizar, identificar, avaliar e mensurar os ovários e as estruturas uterinas, o colo do útero, o corpo do útero, o lúmen, o miométrio e o endométrio, fato nunca relatado na literatura para essa espécie. Esses dados podem ser utilizados como referência para avaliação clínica do trato reprodutivo de fêmeas de Myrmecophaga tridactyla considerada espécie vulnerável, para o diagnóstico de patologias reprodutivas, aplicação de biotecnologias ou avaliação do ciclo estral.(AU)

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

Resumen: Introducción: El síndrome de Klinefelter y sus variantes, como alteración en el número de cromosomas sexuales, se encuentra entre los trastornos del desarrollo sexual. Sus portadores manifiestan hipogonadismo hipergonadotrófico en la pubertad; las variantes severas presentan además problemas neurocognitivos y del lenguaje desde edades tempranas. Objetivo: Describir dos pacientes portadores de mal formación genital con diagnóstico genético de variantes severas de síndrome de Klinefelter; y revisar aspectos clínicos y terapéuticos. Casos Clínicos: Caso 1: Diagnóstico de genitales atípicos al nacer: Falo pequeño y corvo con meato uretral a nivel escrotal y escroto bífido. Sin otra anomalía somática, excepto sutil clinodactilia del 5 dedo. Cariotipo: 49,XXXXY. Al año de vida se reconstruyeron los genitales. Evolucionó con retraso global del desarrollo, principalmente del lenguaje, manejado con estimulación temprana kinésica y fonoaudiológica desde los 2 meses, logró integrarse en un jardín de infantes. Caso 2: Al mes de vida se constató falo pequeño y corvo severo (más de 70°), testículos en bolsa. Cariotipo: 48,XXYY. Al año de vida se corrigió malformación del pene. Evolucionó con retraso global del desarrollo, fundamentalmente en el lenguaje expresivo, y fue manejado con el equipo de estimulación temprana desde los 4 meses, logrando adaptación en un jardín de infantes. Conclusión: Las malformaciones genitales condujeron al diagnóstico de variantes severas de síndrome de Klin efelter, y fueron corregidas alrededor del año de vida. La identificación temprana de estas variantes permitió la intervención del equipo de neuroestimulación, favoreciendo el desarrollo neurocognitivo y la integración social de estos niños.


Abstract: Introduction: Among the disorders of sexual development, Klinefelter syndrome and its variants are classified as an alteration in the number of sex chromosomes. These patients show signs of hypergonadotropic hypogonadism at puberty, however cases of severe variants also present neurocognitive and language problems from an early age. Objective: To describe two patients with genital malformation with genetic diagnosis of severe variants of Klinefelter syndrome, and to review clinical and therapeutic aspects. Clinical Cases: Case 1: Diagnosis of atypical genitalia at birth: Small and curved phallus with the urethral meatus at scrotal level, and bifid scrotum. No other somatic abnormality was observed, except for subtle clinodactyly of the fifth finger. Karyotype: 49, XXXXY. At one year of life, genitalia were reconstructed. The patient presented a global developmental delay, mainly in language, which was managed with early stimulation and speech and language therapy since he was two months old. Finally, he was able to attend kindergarten. Case 2: At one month of life, a small and severe curved phallus (more than 70°) was observed, and testicles were in the scrotum. Karyotype: 48, XXYY. At one year of life, the penile malformation was corrected. The patient presented global developmental delay, mainly in expressive language which was managed with early stimulation since the age of four months, achieving kindergarten attendance. Conclusion: Genital malformations led to the diagno sis of severe variants of Klinefelter syndrome, and were corrected around the year of life. The early identification of these variants allowed the intervention of the neurostimulation team, favoring the neurocognitive development and social integration of these children.

ABSTRACT

Objective: To study current knowledge about genital odors by narrative review and suggest a scientifically validated approach to the problem. Methods: Narrative review taking into account articles published in the last 15 years. Results: Vaginal infections and/or dysbioses are the main causes of bad genital odor, with bacterial vaginosis (BV) being the most frequent finding. The change in the body's smell can be caused by several factors that include everything from food to stress. As the cases of vaginal dysbioses are becoming more and more frequent and the treatments usually recommended do not always solve the problem, the use of vaginal acidifiers has become more recurrent to rebalance the vulvovaginal pH. Despite this, there is not yet a scientifically validated approach to identifying the cause of the odor. Conclusion: Female genital malodor affects women's quality of life and should be investigated and treated accordingly


Objetivo: Estudar por revisão narrativa os conhecimentos atuais sobre odores genitais e sugerir uma forma de abordagem do problema que seja cientificamente validada. Métodos: Revisão narrativa levando em conta artigos publicados nos últimos 15 anos. Resultados: As infecções e/ou disbioses vaginais são as principais causas do mau odor genital, sendo principalmente a vaginose bacteriana (VB) o achado mais frequente. A alteração no cheiro do corpo pode ser provocada por uma série de fatores que incluem desde a alimentação até o estresse. Como a ocorrência de casos de disbioses vaginais vem se tornando cada vez mais frequente e os tratamentos habitualmente recomendados nem sempre resolvem o problema, vem se tornando mais recorrente o uso de acidificantes vaginais com a finalidade de reequilibrar o pH vulvovaginal. Apesar disso, não há ainda um forma de abordagem e de identificação da causa do odor que seja cientificamente validada. Conclusão: O mau odor genital feminino afeta a qualidade de vida das mulheres e deve ser investigado e tratado adequadamente.

ABSTRACT

RESUMEN Fundamento: las infecciones del sistema genitourinario se han identificado entre las más frecuentes en las consultas de la atención primaria de salud; existe un porciento significativo de estudiantes universitarios que las padecen, lo cual repercute en su calidad de vida. Objetivo: elaborar un sistema de actividades para promover el autocuidado del sistema genitourinario en los estudiantes universitarios. Métodos: se realizó una investigación de desarrollo en 2015, en la Facultad de Tecnología de la Salud. Se utilizaron métodos teóricos: histórico-lógico, analítico-sintético e inductivo-deductivo; del nivel empírico: análisis de documentos, observación, cuestionarios y entrevistas a los jóvenes y profesores, y el criterio de especialistas para valorar la propuesta. Resultados: se constató poca percepción de riesgo de los factores que provocan afectaciones en el sistema genitourinario por los jóvenes estudiantes, no habían concientizado el valor del autocuidado para la preservación de su salud y no lo asumían como influyente en la calidad de vida; omitían la responsabilidad individual en la prevención y control de las causas que ejercen influencias negativas en su organismo, por lo que se elaboró un sistema de actividades que fue valorado por criterios de especialistas. Conclusiones: el sistema elaborado promueve el autocuidado del sistema genitourinario a través de la articulación de actividades curriculares y extracurriculares que fomentan actitudes positivas hacia el cuidado del cuerpo y el mejoramiento de la calidad de vida; fue valorado como pertinente y adecuado a los propósitos para los que fue creado.


ABSTRACT Background: the genitourinary system infections have been identified among the most frequent in primary health care consultations; there is a significant percentage of university students who suffer from them, which affect their quality of life. Objective: to develop a system of activities to promote self-care of the genitourinary system in university students. Methods: a development research was carried out in 2015, at the Faculty of Health Technology. Theoretical methods were used: historical-logical, analytic-synthetic and inductive-deductive; empirical ones: analysis of documents, observation, questionnaires and interviews with young people and teachers, and the criteria of specialists to assess the proposal. Results: there was little risk perception of the factors that cause affectations in the genitourinary system of young students, they had not been aware of the self-care value for the preservation of their health and they did not assume it as influencing in life quality; they omitted the individual responsibility in the prevention and control of the causes that exert negative influences in their organism, so a system of activities was elaborated that was valued by criteria of specialists. Conclusions: the elaborated system promotes the self-care of the genitourinary system through the articulation of curricular and extracurricular activities that promote positive attitudes towards the care of the body and the improvement of quality life; it was assessed as relevant and adequate to the purposes for which it was created.

ABSTRACT

Antecedentes. Las masas ováricas son frecuentes en la población pediátrica. Suele realizarse cirugía conservadora de los ovarios porque la mayoría son quistes benignos o funcionales. Objetivo. Investigar quéhallazgos prequirúrgicos sirven para diferenciar la patología de las lesiones ováricas, influir en las decisiones quirúrgicas y predecir la posibilidad de conservar los ovarios. Método. Se incluyeron pacientes operadas con diagnóstico de masa ovárica. Revisión retrospectiva de edad, síntomas, examen físico, marcadores tumorales, características radiológicas y resultados anatomopatológicos. Resultados. Durante el estudio, se operaron 98 pacientes y se incluyeron 86. Media de edad: 9,7 ± 5,62 años. Las patologías no neoplásicas representaron el 68,6 %, las neoplásicas, el 31,4 %, la tasa de malignidad, el 4,6 %. Las neoplasias incluyeron componente sólido, ausencia de torsión ovárica y diámetro >9 cm (p < 0,001;p < 0,001; p = 0,001).Se halló torsión anexial en el 34,9 %. El diámetro medio no difirió significativamente entre los grupos con o sin torsión; la incidencia de torsión fue mayor en las masas <6 cm (p = 0,019). Se realizó cirugía conservadora de los ovarios en 48 pacientes (55,8 %) y ooforectomía, en 38 (44,2 %). El tratamiento dependió de la naturaleza (p < 0,001) y del tamaño (p < 0,001) de la lesión pero no de la edad y la torsión. Conclusión. Una masa puramente quística <9 cm, con torsión y marcadores negativos indica masa no neoplásica. La presencia de un componente sólido y la ausencia de torsión están asociadas con riesgo de cáncer.


Background: Ovarian masses are common in all pediatric age groups. Ovarian-sparing surgery is favored since most cases are benign or functional cysts. Detection of a few malignant cases prevents morbidity and mortality. Objective: to investigate which of the preoperative findings can help to distinguish the pathology of the ovarian lesions, affect the surgical decision and predict the possibility of ovarian preservation. Method: Patients operated with diagnosis of ovarian mass were enrolled in the study between 2000-2015. Age, symptoms, physical examination findings, tumor markers, radiologic features, operative notes, and pathology results were reviewed retrospectively. Results: During the study period, 98 patients were operated and 86 were included. Mean age was 9.7±5.62 years. Non-neoplastic pathologies constitute 68.6 % of cases; 31.4 % was neoplastic. Malignancy rate was 4.6 %. Solid component, absence of ovarian torsion and diameter >9 cm were more commonly seen in neoplastic cases (p<0.001, p<0.001, p=0.001). Adnexal torsion was found in 30 (34.9 %) patients. Mean diameter did not differ significantly between groups with or without torsion; incidence of torsion was greater in patients with masses <6 cm (p=0.019). Ovarian-sparing surgery was performed in 48 (55.8 %) and oopherectomy in 38 (44.2 %) patients. Surgical approach was affected by nature (p<0.001) and size (p<0.001) of the lesion; it was independent of age and presence of torsion. Conclusion: A purely cystic mass <9 cm, with torsion and negative markers, orients towards a non-neoplastic mass. The presence of solid component and absence of torsion are associated with increased risk of malignancy.
