Clinical and laboratory evidence of Trichomonas vaginalis infection among women of reproductive age in rural area.

Background: Vaginitis is a commonly encountered complaint and one of the most frequent reasons for patient visit to obstetrician-gynaecologists. Three vaginal infections are frequent causes of a vaginal discharge: (1) bacterial vaginosis, (2) vulvovaginal candidiasis and (3) trichomonas vaginitis. Differences in the clinical presentation are helpful in diagnosis. Characteristic signs and symptoms for these three vaginal infections are distinct, but on many occasions, they are overlapping. The aim of the present study was to find the prevalence and correlation between the clinical spectrum and laboratory evidence of Trichomonas vaginalis infection by simple, reliable, confirmatory and specific method, i.e. microscopic examination of wet mount preparation and acridine stain of vaginal fluid. Materials and Methods: Irrespective of HIV status, a total of 156 women with vaginal discharge were studied for establishing diagnosis of genital tract infection. The cases of bacterial vaginosis and vulvovaginal candidiasis were excluded from the study. Vaginal speculum assisted high vaginal swabs were collected from women with discharge, during collection vagina was inspected for obvious signs. Results: Of the 156 women with vaginal discharge, 19 (12.06 %) showed T. vaginalis infection. All the women belonged to active reproductive age group, i.e. 20-40 years. Itching dysuria, and offensive, malodorous, thin, yellowish vaginal discharge were the main and consistent complaints. Only in 2 (1.52%) cases, vaginal speculum examination revealed erythema and punctuate haemorrhage, the so-called "strawberry' vagina. The pH was recorded to be >4.5. Conclusion: Clinical differentiation of various forms of infectious vaginitis is unreliable. The prevalence of T. vaginalis infection at 12.06% was found among rural young women of reproductive age using simple and reliable screening wet mount microscopy.

Ocorrência de Trichomonas vaginalis em 100.000 exames citopatológicos cérvico-vaginais diagnosticados entre os anos de 1984 a 1989, em Belo Horizonte, Minas Gerais / Incidence of Trichomonas vaginalis among 100.000 citologic screening tests of routine realized in Belo Horizonte, Minas Gerais during the period 1984 to 1989

Foi verificada a incidência de Trichomonas vaginalis em 100.000 exames citopatológicos de rotina realizados no Laboratório Tafuri de Patologia, em Belo Horizonte, Minas Gerais. Foram encontrados 6.238 casos (6,23 por cento) positivos, no per­odo de 1984 a 1989. A maior incidência foi em 1987 (1.380 casos em 17.433 exames), tendo prevalecido no outono (30,86 por cento) em relaçäo às outras estaçöes do ano. A microflora mais comum foi a mista (Doederlin e cocos), seguida pela Gardnerella vaginalis.

Evaluation of cytological and microbiological methods in diagnosis of vaginal trichomoniasis and candidiasis

600 pregnant women with leukorrhae were examined for the detection of Trichomonus or Candia. Diagnosis was done by cytological [Papanicolaou stained smears] and microbilogical [fresh wet films and culture] procedures, in order to evaluate the best method for diagnosis of these conditions. Trichomoniasis and Candidiasis could be diagnosed by one or more methods in 188 and 150 cases respectively. One single method could diagnose 11.71% of Trichomoniasis and 48.67% of Candidiais, while if two methods were used in comination the percentage were 28.72% and 36% respectively, Moreover, the three methods used together gave the highest diagnositc percentage [59.57% for Trichomoniasis and 14.67% for Candidiasis]. So., it is extremly adisable and important to follow the three methods togther in the diagnosis of these two conditions

Estudio de las alteraciones citomorfológicas del epitelio cervical en tricomoniasis vaginal en 1000 citologías de usuarias del Centro de Salud Cipriana Dueñas por medio del método de papanicolau

El presente es un estudio retrospectivo en el cual se analizaron 1000 resultados citológicos cervicales realizados en el Centro de Salud Docente Asistencial Cipriana Dueñas en 1998. Todas las citologías proceadas y estudiadas en el Centro de Salud, encontrándose 24 casos de infecciones por tricomoniasis y citologías clase II, según el método de papanicolau lo que corresponde al 2.4 por ciento del total de exámenes en estudio. La edad de las usuarias va desde los 19 hasta los 72 años, con gestaciones de 1 a 9, y con el uso de los diferentes métodos de planificación familiar las que se encuentran en edad fértil. La literatura hasta antes de la década de los 90 habla de porcentajes altos sobre infección genital por tricomonas y las características citomorfológicas en presencia del parásito...
