Caracterización sociodemográfica y perfil clínico de pacientes con diagnóstico de neurosífilis en una población de Bogotá, Colombia / Socio-demographic characterization and clinical profile of patients diagnosed with neurosyphilis in a population of Bogotá, Colombia

RESUMEN INTRODUCCIÓN: La neurosífilis se asocia con una serie de signos y síntomas que pueden aparecer luego de 10 a 30 años de la primoinfección; es más frecuente en pacientes con VIH, conductas homosexuales y adultos de género masculino. Es una enfermedad tratable, cuya incidencia viene en descenso notorio tras el advenimiento de la terapia antibiótica de fácil acceso, lo que la convierte en un problema de salud pública a escala mundial. OBJETIVO: Determinar la prevalencia y las variables sociodemográficas, clínicas y paraclínicas de los pacientes con diagnóstico de neurosífilis tratados en la Unidad de Servicios de Salud Occidente de Kennedy (USSOK), Bogotá, Colombia, entre el 2014 y el 2018. PACIENTES Y MÉTODOS: Se llevó a cabo un estudio observacional analítico de corte transversal, retrospectivo, en el que se evaluó a pacientes con diagnóstico de neurosífilis que recibieron manejo en la USS Occidente Kennedy durante 2014-2018. Para tal fin se incluyó a mayores de 18 años con diagnóstico de neurosífilis, y se hizo estudio de líquido cefalorraquídeo, pruebas no treponémicas en las que se usó el VDRL y pruebas treponémicas en las cuales se empleó FTA-Abs. RESULTADOS: Se diagnosticaron 55 casos de neurosífilis durante el periodo estudiado. Si se tiene en cuenta el número total de pacientes atendidos (8244), la prevalencia calculada correspondió a 0,66 %. CONCLUSIONES: En nuestro medio, la prevalencia de neurosífilis (0,6 %) es mayor a la reportada en poblaciones de altos ingresos económicos (0,4 %). El perfil sociodemográfico de pacientes con diagnóstico de neurosífilis de una población de bajos recursos se caracteriza por: adultos en la sexta década de la vida, sexo masculino e inmunocompetentes.

SUMMARY INTRODUCTION: Neurosyphilis is associated with a series of signs and symptoms that may appear 10 to 30 years after the first infection; it is more frequent in patients with HIV, homosexual behavior and male adults. It is a treatable disease, whose incidence comes in a noticeable descent after the advent of easily accessible antibiotic therapy, which makes it a public health problem worldwide. OBJECTIVE: To determine the prevalence, sociodemographic, clinical and paraclinical variables of patients diagnosed with Neurosyphilis treated in the Kennedy West Health Services Unit (USSOK) between 2014-2018 PATIENTS AND METHODS: An observational, cross-sectional, retrospective, observational study was carried out in which patients diagnosed with Neurosyphilis who received management at the USS West Kennedy during 2014-2018 were evaluated. They were older than 18 years, with a diagnosis of Neurosyphilis. Cerebrospinal fluid study, non-treponemal tests where VDRL was used and treponemal tests using FTA-Abs RESULTS: 55 cases of neurosyphilis were diagnosed during the period studied. Taking into account the total number of patients treated (8244), the calculated prevalence corresponded to 0.66 % CONCLUSIONS: The prevalence of Neurosyphilis in our environment (0.6 %) is higher than that reported in high income populations (0.4 %). The sociodemographic profile of patients diagnosed with neurosyphilis from a low-income population is characterized by: adults in the sixth decade of life, male and immunocompetent.

Effects of perinatal period administration of clomiphene citrate in sexual behavior, organ weights and hormone concentration of Wistar male and female rats / Efeito da administração do citrato de clomifeno durante o período perinatal no comportamento sexual, peso dos órgãos e concentração hormonal de ratos Wistar machos e fêmeas

The effects of prenatal exposure to clomiphene citrate in sexual behavior, organ weight and hormone concentrations of male and female rats was evaluated. The animals received four doses of clomiphene citrate 2 mg/mL each during the prenatal period (21 days of gestation DG21) on days 1 (DN1), 2 (DN2) and 3 (DN3) after the birth of the puppies. The treatment led to the development of polycystic ovaries in 70% of the females, masculinization of female sexual behavior and changes in sexual behavior of males evidenced by the reduction in the number of ejaculations. In regards to hormone levels, a decrease in the FSH levels in male offspring was observed. It was concluded that clomiphene citrate interferes with the reproductive capacity of male and female rats and female sexual orientation when prenatally administered.

Foram investigados os efeitos da exposição perinatal ao citrato de clomifeno no comportamento sexual, peso dos órgãos e concentração hormonal de ratos machos e fêmeas. Os animais receberam quatro doses de 2 mg/mL de citrato de clomifeno, no período perinatal (21 dias de gestação DG21), nos dias 1 (DN1), 2 (DN2) e 3 (DN3) após o nascimento dos filhotes. O tratamento causou desenvolvimento de ovário policístico em 70% das fêmeas, masculinização do comportamento sexual das fêmeas e alteração do comportamento sexual dos machos evidenciado pela redução no número de ejaculações. Em relação aos níveis hormonais, observou-se diminuição de FSH na prole masculina. Concluiu-se que o citrato de clomifeno interfere na capacidade reprodutiva de ratos machos e fêmeas, e na orientação sexual de fêmeas, quando administrado perinatalmente.

Orientación sexual en adolescentes y jóvenes mexicanos de 12 a 29 años de edad / Sexual orientation among 12 to 29 year-old mexican adolescent and youths

Los objetivos del artículo fueeron describir la prevalencia de identidad no heterosexual y pronosticar su presencia o ausencia con datos de la segunda Encuesta Nacional de la Juventud (ENJUVE, 2005). En una muestra probabilística de 25.630 mexicanos de doce a diecinueve años de ambos sexos. La prevalencia de orientación no heterosexual autodefinida fue 2,5% en hombres y 1,1% en mujeres. La identidad no heterosexual es pronosticada por género masculino, haber tenido relaciones homosexuales, enamorarse de personas del mismo género y ausencia de adscripción religiosa, es decir, factores facilitadores que implican el mayor impulso de la sexualidad masculina, integrar la propia conducta homosexual, reconocer el deseo homosexual y liberarse de la condena moral que acarrea la concepción judeocristiana de la homosexualidad. Finalmente, estos datos nos hablan de una realidad que está presente para ser escuchada y respetada.

The aims of this paper were to describe the prevalence of self-defined sexual orientation, and to predict its presence or absence with the second National Survey of the Youth (ENJUVE, 2005) data. In a probability sample of 25,630 Mexicans of 12 to 29 year-old women and men, the prevalence of the non-heterosexual identity was 2.5% men and 1.1% women. The non-heterosexual identity was predicted by masculine gender, homosexual intercourses, falling in love with a person of the same gender and absence of religious adscription, that is, facilitating factors that imply the greater impulse of the masculine sexuality, to integrate the own homosexual behavior, to recognize their homosexual desire, and to free themselves from the moral condemnation that endures the Judeo-Christian conception of the homosexuality. The data show a reality to be listened to and respected.
