Office Hysteroscopy as a Valid Tool for Diagnosis of Genital Tract Lesions in Females with Intact Hymen.

ABSTRACT: Background:To evaluate the feasibility and applicability of using office hysteroscopy in women with intact hymen. Methods:We recruited 836 patients with intact hymen with different indications who underwent diagnostic hysteroscopy without anesthesia in an outpatient setting from 2007 to 2016 at Chang Gung Memorial Hospital at Linkou. Results:Patients' mean age was 35?±?10.6 years (range 3-69 years). Most patients (86.4%) with postmenopausal bleeding had intrauterine lesions, and they were especially at high risk (50%) for endometrial hyperplasia or malignancy. Five hundred thirty (63.3%) patients had histologic findings confirming concordance between hysteroscopic and histologic findings. Submucosal myoma had the highest concordance (96.3%), whereas endometrial hyperplasia had the lowest concordance (50%). Forty-eight patients (5.7%) had endometrial hyperplasia, and 35 patients (4.2%) had endometrial malignancy. Two patients who were thought to have nonspecific endometrial thickening actually had endometrial pathology. Conclusions:Hysteroscopy through vaginoscopic approach is feasible and well-tolerated in the patients with intact hymen. This outpatient procedure provides accurate evaluation of lesions of the genital tract and should be considered in patients without a history of intercourse.

Project description:ObjectivesTo evaluate whether urodynamic investigation (UDI), the gold standard to assess refractory lower urinary tract symptoms (LUTS), is appropriate to select healthy volunteers with apparent normal lower urinary tract function as control subjects for comparative studies.Subjects and methods42 healthy subjects (22 women, mean age 32±10 years; 20 men, mean age 37±12 years) without LUTS were included into this prospective single-centre cohort study. All subjects recorded a 3-day bladder diary, completed validated questionnaires regarding LUTS, and underwent neuro-urological assessment as well as free uroflowmetry. Same session repeat UDI was performed according to "Good Urodynamic Practice" recommended by the International Continence Society, but using an air-charged instead of a water-filled catheter, and evaluated by a blinded investigator.ResultsAll 3-day bladder diaries, LUTS questionnaires, neuro-urological assessments and free uroflowmetries were within normal limits. Overall (either during the first or second UDI), same session repeat UDI revealed pathological findings in 71% (30/42): Detrusor overactivity was detected in 14% (3/22) and 30% (6/20), post void residual >100mL in 14% (3/22) and 25% (5/20), bladder outlet obstruction in 9% (2/22) and 20% (4/20) and detrusor sphincter dyssynergia in 77% (17/22) and 65% (13/20) of our women and men, respectively. Repeatability of detrusor overactivity (κ = 0.78, 95% CI: 0.54-1.02) and detrusor sphincter dyssynergia (κ = 0.77, 95% CI: 0.55-0.98) showed substantial agreement between both UDIs. All other assessed urodynamic parameters had wide 95% limits of agreement for differences in the parameters indicating poor repeatability.ConclusionsMore than 70% of our healthy subjects showed pathological urodynamic findings. Although UDI is the gold standard to assess refractory LUTS, it seems not to be applicable in healthy subjects to define normal lower urinary tract function. Therefore, we do not recommend using UDI to select healthy control subjects.

Project description:Chlamydia spp. productively infect mucosal epithelial cells of multiple anatomical sites, including the conjunctiva, lungs, gastrointestinal (GI) tract, and urogenital tract. We, and others, previously established that chlamydial GI tropism is mediated by distinct chromosomal and plasmid factors. In this study, we describe a genital infection-attenuated Chlamydia muridarum mutant (GIAM-1) that is profoundly and specifically attenuated in the murine genital tract. GIAM-1 infected the murine GI tract similarly to wild-type (WT) Chlamydia muridarum but did not productively infect the lower genital tract of female mice, ascend to infect the upper genital tract, or cause hydrosalpinx. However, GI infection of mice with GIAM-1 elicited a transmucosal immune response that protected against subsequent genital challenge with WT Chlamydia muridarum Collectively, our results demonstrate that chlamydia mutants that are profoundly attenuated for specific organ tissues can be derived and demonstrate that live-attenuated vaccine strains that infect the GI tract, but do not elicit genital tract disease, could be used to protect against chlamydia genital tract infection and disease.IMPORTANCE Chlamydia is the most common sexually transmitted bacterial infection in the United States. Most chlamydia genital infections resolve without serious consequences; however, untreated infection in women can cause pelvic inflammatory disease and infertility. Antibiotics are very effective in treating chlamydia, but most genital infections in both men and women are asymptomatic and go undiagnosed. Therefore, there is a critical need for an effective vaccine. In this work, we show that a mutant chlamydia strain, having substantially reduced virulence for genital infection, colonizes the gastrointestinal tract and produces robust immunity to genital challenge with fully virulent wild-type chlamydia. These results are an important advance in understanding chlamydial virulence and provide compelling evidence that safe and effective live-attenuated chlamydia vaccines may be feasible.
