The Additive Value of Pelvic Examinations to History in Predicting Sexually Transmitted Infections for Young Female Patients With Suspected Cervicitis or Pelvic Inflammatory Disease.

STUDY OBJECTIVE: We evaluate the additive value of pelvic examinations in predicting sexually transmitted infection for young female patients with suspected cervicitis or pelvic inflammatory disease in a pediatric emergency department (ED). METHODS: This was a prospective observational study of female patients aged 14 to 20 years who presented to an urban academic pediatric ED with a complaint of vaginal discharge or lower abdominal pain. Enrolled patients provided a urine sample for chlamydia, gonorrhea, and trichomonas testing, which served as the criterion standard for diagnosis. A practitioner (pediatric ED attending physician, emergency medicine or pediatric resident, pediatric ED fellow, or advanced practice provider) obtained a standardized history from the patient to assess for cervicitis or pelvic inflammatory disease according to the Centers for Disease Control and Prevention criteria. They then recorded the likelihood of cervicitis or pelvic inflammatory disease on a 100-mm visual analog scale. The same practitioner then performed a pelvic examination and again recorded the likelihood of cervicitis or pelvic inflammatory disease on a visual analog scale with this additional information. Using the results of the urine sexually transmitted infection tests, the practitioner calculated and compared the test characteristics of history alone and history with pelvic examination. RESULTS: Two hundred eighty-eight patients were enrolled, of whom 79 had positive urine test results for chlamydia, gonorrhea, or trichomonas, with a sexually transmitted infection rate of 27.4% (95% confidence interval [CI] 22.6% to 32.8%). The sensitivity of history alone in diagnosis of cervicitis or pelvic inflammatory disease was 54.4% (95% CI 42.8% to 65.5%), whereas the specificity was 59.8% (95% CI 52.8% to 66.4%). The sensitivity of history with pelvic examination in diagnosis of cervicitis or pelvic inflammatory disease was 48.1% (95% CI 36.8% to 59.5%), whereas the specificity was 60.7% (95% CI 53.8% to 67.3%). The information from the pelvic examination changed management in 71 cases; 35 of those cases correlated with the sexually transmitted infection test and 36 did not. CONCLUSION: For young female patients with suspected cervicitis or pelvic inflammatory disease, the pelvic examination does not increase the sensitivity or specificity of diagnosis of chlamydia, gonorrhea, or trichomonas compared with taking a history alone. Because the test characteristics for the pelvic examination are not adequate, its routine performance should be reconsidered.

[Prevalence and determining factors of acquiring C. trachomatis infection among adolescents and young adults in Catalonia]. / Prevalencia de la infección por C. trachomatis y N. gonhorroeae y determinantes para su adquisición en jóvenes y adultos-jóvenes en Cataluña.

OBJECTIVE: To determine the prevalence of Chlamydia trachomatis (C. trachomatis) and Neisseria gonorrhoeae (N. gonhorroeae) infections and the risk factors for acquiring them in individuals under 35 years-old attending sexual health clinics in Barcelona province in 2006. METHODS: Cross-sectional study of a convenience sample of 500 adolescents and young adults aged between 16 and 35 years. A total of 423 samples were analysed using real-time PCR. A standardised questionnaire was used to collect clinical, epidemiological, and behavioural data on the participants. Significant differences were analysed in the descriptive study using Pearson's ((2). The association between C. trachomatis infection and its determining factors was analysed using the Mantel-Haenszel test and a multivariate logistic regression model. RESULTS: The overall prevalence of C. trachomatis was 4%, and was significantly higher in those under 25 years of age. The overall prevalence of N. gonhorroeae was 0.2%. The independent risk factors for infection by C. trachomatis were as follows: foreign origin (OR: 3.74; CI 95%: 1.10-12.72), having had a sexual partner in the last 3 months (OR 3.91; CI 95%: 1.30-11.81), and tobacco use the last 12 months (OR: 4.99; CI 95%: 1.34-18.59). CONCLUSIONS: This is the first study performed in Catalonia that shows high prevalence of C. trachomatis in young people, thus confirming trends in the rest of Europe. Systematic monitoring of C. trachomatis infection in sentinel populations will provide valid information allowing us to assess the relevance of proposing targeted screening programs in our setting.

Leukocyturia in women with diabetes and its clinical implications.

BACKGROUND: Urinalysis is one of the most common studies performed on the diabetic patient at every visit. The presence of leukocyturia is relatively common but it is not clear what the attitude of the physician toward this particular finding should be. The main objective of the present study was to investigate the clinical significance of leukocyturia in diabetic women. METHODS: Ninety-eight diabetic women (84.7% type 2) aged 57 +/- 13 years who were being seen at the diabetic out-patient clinic were randomly selected. All patients underwent a clinical and gynecologic examination and a urinalysis. A Papanicolaou smear and a urine culture were also obtained. RESULTS: The overall prevalence of leukocyturia (>5 cells/high power field (hpf)) was 46.5%. Patients with urinary tract infections (UTI) were 7.5 times more likely to have leukocyturia, while a leukocyte count <5cells/hpf predicted the absence of UTI in 96% of the women. In the comparison of patients with and without leukocyturia, we found that proteinuria (p = 0.06) and bacteriuria (p <0.002) were more common in the women with leukocyturia. A significant association with leukorrhea was not demonstrated. The empirical use of antibiotics was 12 times more frequent in the patients with leukocyturia. CONCLUSIONS: A urinary culture should be requested in all diabetic patients with leukocyturia. The possibility of a UTI is remote when leukocyturia is absent.

Detection of Chlamydia trachomatis in urine samples by polymerase chain reaction and enzyme immunoassay.

First-void urine samples collected from sexually transmitted diseases (STD) clinic patients were examined by a nested polymerase chain reaction (PCR) and a commercial enzyme immunoassay (IDEIA Chlamydia) for the diagnosis of Chlamydia trachomatis urethritis or cervicitis. The primers for the PCR amplified a target in the major outer membrane protein (MOMP) gene in C trachomatis while the IDEIA detected genus-specific chlamydial lipopolysaccharide. Discrepant results were resolved by retesting urine specimens with a second (plasmid-based) PCR and taking urethral or endocervical swab results into consideration. For 231 men (chlamydial prevalence 20.4%), the sensitivity, specificity, positive and negative predictive values were 59.6%, 99.5%, 96.6% and 90.6% for urine IDEIA, 68.1%, 99.5%, 97% and 92.4% for urethral swab IDEIA and 97.9%, 99.5%, 97.9% and 99.5% for urine PCR. The corresponding rates for 66 women (chlamydial prevalence 54.6%) were 19.4%, 100%, 100% and 50.8% for urine IDEIA, 86.1%, 96.7%, 96.9% and 85.3% for endocervical swab IDEIA and 91.7%, 93.3%, 94.3% and 90.3% for urine PCR. Hence, in a high prevalence population, the urine IDEIA was a suitable alternative to the male urethral swab IDEIA but significantly less sensitive than the endocervical swab IDEIA. The urine PCR was, however, much more sensitive than the urine IDEIA for both men and women and could replace the endocervical swab IDEIA for the diagnosis of chlamydial cervicitis.

[Chlamydia trachomatis infection of the urogenital system in our clinical experience]. / Zakazenie Chlamydia trachomatis ukladu moczoplciowego we wlasnej obserwacji klinicznej.

The increased number of the genitourinary system infection caused by Chlamydia trachomatis (Ch. Tr.), increased number of patients with dysuria or sterile leukocyturia gave stimulus to studies of 615 patients from Department of Nephrology and District Outpatient Nephrological Care Unit with regard to infections with that microbes. Material for investigations derived from urethra. Diagnostic examinations were performed using the Mc Coy cell culture and the immunofluorescence method. The infection was noted in 176 patients (119 women and 57 men) that is in 28.6% of cases studied. The mean age of patients was 42.7 +/- 12 years. Clinical symptoms such as dysuria or frequency were typical for that kind of infection. The most frequent abnormality was leukocyturia or leukocyturia accompanied by erythrocyturia noted in 66% of patients. Isolated erythrocyturia was observed in 24.4% of cases. It has been stated that anamnesis or routine laboratory examinations were not able to the identification of infection. In face of poorly characteristics of clinical picture of infection the infection with Ch.Tr. could be the cause of unsuccessful therapy in patients with signs of genitourinary tract infections.

[Clinical studies on doxycycline treatment of urogenital Chlamydia trachomatis infections].

Nineteen patients of male NGU and 8 patients of female NGC were treated with doxycycline (DOXY, 200 mg/day for 14 days). C. trachomatis positive rate of male NGU was 12/19 (63%), and that of female NGC was 4/8 (50%). C. trachomatis positive rate of male NGU after treatment of DOXY for 3 days, 7 days and 14 days, was 83%, 17% and 0%, respectively. Serous discharge after treatment of DOXY for 3 days, 7 days, 14 days, was continued in 100%, 33%, 0%. Administration of DOXY (200 mg/day for 14 days) was considered good treatment for male C. trachomatis positive NGU.

Urinary cyclic nucleotides and the cytopathology of human uterine cervical dysplasias.

Blinded urinary assays for cyclic guanosine 3':5'-monophosphate (cGMP) and cyclic adenosine 3':5'-monophosphate (cAMP) were performed on 49 subjects with documented abnormal cervical cytology and 21 control subjects with normal cytology. A significant difference in the mean cGMP:cAMP ratios between the case and control groups was found. A significantly greater proportion of women with cytological abnormalities had a cGMP:cAMP ratio above the 0.2 level (p less than 0.001). Cases treated surgically for severe dysplasia or carcinoma in situ of the cervix revealed a significant postsurgical fall in the cGMP:cAMP ratios (p less than 0.025). The possibility of utilizing urinary ratios of cyclic nucleotides as an objective index in the detection, monitoring of progression, and therapy of preneoplastic cervical lesions is discussed.
