To determine the rate of occurrence of Gardnerella vaginalis in the genital tract and rectum of the asymptomatic prepubertal boy and to examine the effect of circumcision on the rate of recovery.
A prospective survey design was used. Cultures for G vaginalis were obtained from the urethral meatus, surrounding glans, and rectum of prepubertal boys. Boys who had a history of sexual abuse, current urogenital symptoms, or who had taken antibiotics in the preceding 2 weeks were excluded from this study.
The study was conducted in ambulatory clinical settings at a children's hospital within a major medical center that serves as a statewide referral center.
A group of 99 circumcised and uncircumcised prepubertal boys participated in the study. The participants ranged in age from 1 month to 7 years 4 months.
Results of cultures for G vaginalis.
No cultures were positive for G vaginalis from the urethra, glans, or rectum in any of the participants in this study.
The findings of this study provide preliminary evidence that G vaginalis is not an organism that commonly colonizes the urogenital or gastrointestinal tract in asymptomatic prepubertal boys. Based on these findings, it does not seem prudent to apply the concept of asymptomatic colonization to prepubertal boys unless further studies refute these findings.
确定无症状青春期前男孩生殖道和直肠中阴道加德纳菌的发生率,并研究包皮环切术对其检出率的影响。
采用前瞻性调查设计。从青春期前男孩的尿道口、龟头周围和直肠获取阴道加德纳菌培养物。有性虐待史、当前泌尿生殖系统症状或在过去2周内服用过抗生素的男孩被排除在本研究之外。
该研究在一家大型医疗中心的儿童医院的门诊临床环境中进行,该儿童医院是全州的转诊中心。
一组99名接受过包皮环切术和未接受过包皮环切术的青春期前男孩参与了研究。参与者年龄从1个月至7岁4个月不等。
阴道加德纳菌培养结果。
本研究中所有参与者的尿道、龟头或直肠的培养物均未检测出阴道加德纳菌阳性。
本研究结果提供了初步证据,表明阴道加德纳菌并非无症状青春期前男孩泌尿生殖道或胃肠道的常见定植菌。基于这些发现,除非进一步研究反驳这些结果,否则将无症状定植的概念应用于青春期前男孩似乎并不谨慎。
