ABSTRACT
There are more than 30 different sexually transmissible agents while the most common one is Chlamydia trachomatis. In this prospective study, we decided to compare the prevalence of infection in symptomatic and asymptomatic females. Two hundred sixty urine samples of women in two groups [symptomatic and asymptomatic] were collected from patients attending Mehrad Hospital in Tehran, Iran and tested by polymerase chain reaction. Thirty nine women in both groups were infected [14.99%], while 27/130 subjects were in symptomatic group [20.76%], compared with 12/130 person in asymptomatic group [9.23%]. No statistically significant difference was found between two groups. Data analysis showed infection with C. trachomatis in symptomatic women to be significantly associated with history of sexually transmitted infections, white blood cells in urine and epithelial cells in urine. The present study recommends that targeted screening programs in high risk sexually active women [like as individuals who had a history of STIs] are needed as part of case-finding strategies and treatment
ABSTRACT
Mouthwashes like brush and dental floss, can cause reduction in dental plaque and gingivitis. An optimal mouthwash should have antimicrobial properties, low drug resistance, and cause no decrease in normal microflora of the mouth. The purpose of this study was the evaluation of the effects of chlorhexidine 0.12% mouthwash on pathogen streptococcus and normal microflora of the mouth. In this experimental study, based on selected inclusion criteria, 28 subjects, were selected and asked to use 0.12% chlorhexidine mouthwash for 2 weeks, according to the manufacturer instruction. Before and after rinsing with the mouthwash, subjects were requested to wash their mouth with physiologic serum. After washing, 1cc of saliva of each individual was collected in sterile tube and immediately sent to microbiology laboratory. This process was repeated 2 weeks after using mouthwash. The number of pathogen streptococcus and normal microflora colonies of the mouth before and after using chlorhexidine were recorded. For analyzing the data, T and Chi Square Test were used.: Chlorhexidine mouthwash [0.12%] significantly decreased numbers of the pathogen streptococcus and mouth normal microflora [p <0/05] This study showed that, 0.12% chlorhexidine mouthwash, can destroy not only the mouth pathogen streptococci, but also the normal microflora of the mouth. The latter should be considered as its side effect
