    Description: For a series of data points that follow a pattern due to natural ordering, I develop a modified runs test for continuous data to detect such a pattern. The test statistic is the number of runs in the series after having smoothed the data with use of a moving average. The testing procedure is based on permutations of the original data. My simulations indicate that the modified test is generally more powerful than the usual runs test.

    Description: To determine the recurrence rate of chlamydial infections, we initially screened an urban population of 1308 sexually active female adolescents for chlamydial infection at the urethral and endocervical sites; these young women were followed and had additional examinations for infection. Chlamydial infection was documented by tissue culture in 31.1% (407) of them at some time during the study. After appropriate antibiotic treatment, 68.3% (278/407) returned for test-of-cure cultures within 3 months of their initial infection; of those 278, a total of 254 had sterile cultures. These patients were followed to determine the recurrence rate of chlamydial infections. Of these 254 patients, 177 (69.7%) had one or more follow-up visits; 38.4% (68/177) had a recurrent chlamydial infection. The majority of recurrent infections were documented within 9 months of the initial infection. Recurrent infections with the same serovar were frequent, suggesting reinfection by untreated partners or possible relapse of the initial chlamydial infection. This high rate of recurrent infection suggests that female adolescents should be rescreened frequently for genitourinary chlamydial infections.

    Description: Five hundred sixty-eight adolescent female patients receiving routine gynecologic care at urban clinics were screened by culture for infection at both the urethra and endocervix. Culture results for 562 were available from either or both sites. Positive cultures were obtained from 139 (25%). Urethral infection was not associated with either urinary tract symptoms or sterile pyuria, but urethral or endocervical infection was associated with cervical friability (P=〈0.0001), endocervical mucopus (P=0.0001), cervical erythema (P=0.0002), and cervical ectopy or erosion (P=0.01). Increased chlamydial infection rates were associated with older age (P=0.01), history of more frequent intercourse (P=0.01), and history of more than one lifetime partner (P=0.023), with a marginal association for being black (P=0.05). Method of contraception, reason for attending clinic, age at menarche, age at first intercourse, years sexually active, number of sexual partners in preceding 6 months, parity, and prior history of sexually transmitted disease were not associated with having chlamydial genitourinary infection.

    Description: The relationship between acute inflammation and serovar of Chlamydia trachomatis was evaluated in patients with genital chlamydial infection who attended a sexually transmitted diseases clinic. Polymorphonuclear leukocytes (PMNLS) were enumerated on Gram's stained smears of endourethral contents in men; cervicitis was scored by visual observation of the endocervix in women. Isolates were serotyped with a monoclonal antibody-based radioimmunoassay. The distribution of serovars in 99 women did not differ in the presence or absence of cervicitis or concurrent gonorrhea. An overall difference (P = .037) was observed when serovar distributions in men with lt;3 PMNLs (n = 42), gt;10 PMNLs (n = 41), and gonococcal urethritis (n = 42) were compared. Follow-up pairwise comparisons revealed that men with lt;3 PMNLs had fewer isolates of serovars F and G than did men with gt;10 PMNLs (P 〈.05). No strong overall association was observed between inflammation and serovar.

    Description: The present study was undertaken to evaluate the utility of a gram stain of endocervical secretions in the prediction of endocervical infection with Chlamydia trachomatis. Endocervical examinations, Gram stains and chlamydial cultures were performed on 214 women who were attending a sexually transmitted diseases clinic and were at increased risk for chlamydial infection. Almost 24% of the Gram stains were judged inadequate because of the presence of ectocervical material. However, significantly higher isolation rates for C. trachomatis were found for those women with valid smears and 10 or more polymorphonuclear cells on their smear (44% vs 19%, P = .0008). This relationship was independent of the presence of gonococcal infection. Based on the results of this study, endocervical Gram stains appear to be a valuable screening tool for chlamydial infection, particularly among those without mucopurulent discharge.

    Description: In developed nations, the most common sexually transmitted disease is infection with Chlamydia trachomatis. In the United States, the standard therapy for chlamydia infections involves a seven-day treatment period with tetracycline, erythromycin, or doxycycline. However, some cases require a longer treatment period, up to 21 days, to eliminate the infection. After the treatment period has ended, the patient is retested to make sure that the infection has been cured. This procedure is called a test-of-cure (TOC). But recurrent infections with the same strain of Chlamydia trachomatis, following seven days of treatment and TOC, are not uncommon, and may indicate that the standard therapy time should be increased. In an attempt to evaluate the relationship between the duration of treatment and the rate of recurrence of infection, the medical records of 2,983 patients, who were treated with the standard therapy for chlamydia infection, were reviewed. During a two-year follow-up period, the rate of recurrence of infection was 29 percent. Recurrence of infection was associated with young age, but not with gender or race. To determine if a longer treatment period could reduce the rate of recurrence of infection, 220 patients with chlamydia were treated with tetracycline for either 7 or 21 days. Among patients who returned, the recurrence rate was 14 percent for the seven-day treatment and 18 percent for the 21-day treatment. The difference in the recurrence rate between the two treatment groups was not statistically significant. It is concluded that a 21-day treatment period is no more effective than a seven-day treatment period in preventing recurrence of chlamydia infection.

    Description: Control of bacterial sexually transmitted diseases (STD) depends on adequate antibiotic therapy. During a 4-week period, a survey concerning compliance was administered to all patients attending an STD clinic who were being treated with one of the standard antibiotic regimens for presumed gonococcal or chlamydial infections. Of the 497 eligible patients, 406 (81.7%) were surveyed between 24 hours and 72 hours after the end of treatment. Of those being treated with the standard 7-day regimen of tetracycline or erythromycin, 63.4% complied. Compliance was not associated with race, gender, symptoms, or antibiotic regimen. Those who were younger, were sexual contacts of an infected partner, or had gastrointestinal side effects were more likely not to comply with treatment.

    Description: BACKGROUND AND OBJECTIVES:: GOALS:: STUDY DESIGN:: The study population consisted of all 4,329 sexually active girls between the ages of 13 and 19 attending the four adolescent health clinics in Indianapolis, Indiana, during the period beginning October 1, 1985, and ending June 30, 1994. All girls were cultured for Chlamydia trachomatis, and behavioral data were collected for those attending the clinics before 1989. The trend in quarterly isolation rates was examined using linear regression analysis. RESULTS:: Results showed that there was a significant decrease (P = 0.0001), from 25.9% to 9.7%, in the first-visit chlamydial isolation rate over the study period. Behavioral data showed decreases in the frequency of sexual intercourse and in lifetime years of sexual activity, as well as an increase in condom use. CONCLUSIONS::
