AIDS/HIV knowledge level and perceived chance of having HIV among rural adolescents.

Behaviors that increase the risk of acquired immunodeficiency syndrome (AIDS) and human immunodeficiency virus (HIV) among adolescents living in rural areas have been reported to be as frequent as those of lower socioeconomic minority youth living in large urban areas. Little is known, however, about whether rural adolescents possess adequate knowledge upon which to make responsible decisions to avoid exposure to HIV. In order to address this deficit, we administered the Centers for Disease Control (CDC) 1989 Secondary School Health Risk Survey to 294 sixth, seventh, and eighth grade students (30.2% sample) from a rural county with significant social problems including epidemic sexually transmitted diseases STDs, sex-for-drugs, poverty, and drug abuse. The sample was 65% African-American, 50% female, with a mean age of 12.9 +/- 1.3 years. Although 68% reported having received school-based AIDS education, a lower proportion (greater than or equal to 10%) the students were found to correctly answer 8 of 17 AIDS/HIV knowledge questions than those from a national comparison group. The mean was 12.8 +/- 3.1 of 17 items answered correct. Lower AIDS/HIV knowledge was associated with lower school grade (rho = 0.46, p less than or equal to 0.0001); being African-American, Hispanic, or Native American (p less than or equal to 0.043); and never receiving school-based AIDS/HIV education (p less than or equal to 0.0001). Based on multivariate analysis of variance (ANOVA), only school-based AIDS/HIV education was a significant predictor (p less than or equal to 0.0001) of knowledge.(ABSTRACT TRUNCATED AT 250 WORDS)

Sexually transmitted disease treatment and return for test of cure of adolescents in a family planning clinic.

This retrospective study assessed the return for treatment and test-of-cure rates for gonorrhea and chlamydial infection among 154 adolescents and young adults attending a family planning clinic. Eighty-four percent returned for treatment and 57% of those returned for a test of cure. No statistical differences in race/ethnicity, marital status, gravida, age, presence of symptoms, or type of infection were found between those returning and those not returning for treatment. Issues associated with sexually transmitted disease treatment and follow-up in the family planning clinic setting are discussed.

Vaginal douching in teenagers attending a family planning clinic.

This study assessed the knowledge and usage patterns of vaginal douching in sexually active teenagers attending a family planning clinic. A questionnaire was administered consecutively to 94 black, 36 Hispanic, and 12 Anglo females ranging in age from 13 to 19 years. The survey showed that vaginal douching is a common practice, with almost two thirds learning about douching from their mother. The technique is primarily used for hygienic reasons with few using it to prevent pregnancy or infection. Age of first douche correlated with age of first intercourse (p less than 0.001). Almost 23% had douched within 2 days of the clinic visit, and 56% reported douching one or more times a week.

Hydrostatic pressure-induced colon trauma from a pool whip.

Hydrostatic pressure-induced colon injury is a rare occurrence in the pediatric population. We present a case of massive hydroperitoneum following a pool whip-induced injury. Although tension pneumoperitoneum or hydroperitoneum is rare, prompt recognition and surgical intervention are essential.

Predominant sexually transmitted diseases among different age and ethnic groups of indigent sexually active adolescents attending a family planning clinic.

The present study analyzed a group of 113 sexually active, indigent female adolescents attending a family planning clinic, for age, ethnic, or racial trends in the recovery of Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma species, and Ureaplasma urealyticum. The overall recovery rate for N. gonorrhoeae was 8/112 (7.1%), with the highest rate occurring in black patients (7/82, 8.5%). The overall recovery rate for C. trachomatis was 31/113 (27.4%), with the highest rate occurring in Hispanics (7/21, 33.3%). The isolation of C. trachomatis was evenly divided among patients grouped by reason for visit. Neisseria gonorrhoeae, on the other hand, was isolated more frequently from patients coming for a sexually transmitted disease screen than from those attending for other reasons. There was a significant (p less than 0.05) increase in isolation of Mycoplasma species from 18-19-year-old patients, but no such difference was observed for U. urealyticum when compared to younger age groups. Factors associated with venereal disease prevalence in our teenage indigent population as well as implications for the future reproductive health of such patients are discussed.

Automated quantitative fluorescent image analysis of cervical cytology.

Cervical cytology from 122 patients with histories of one or more abnormal Pap smears were studied using slide-based automated quantitative fluorescence image analysis (QFIA) in order to determine the usefulness of the QFIA technique in detecting neoplasias. The purpose of the study was to evaluate the accuracy and validity of QFIA as a cytological method for the early detection of cervical cancer, based on comparisons with the conventional Pap smear and histopathology. The results of the analysis demonstrated that the sensitivity of the automated QFIA cytology was 100% for high-grade neoplasms (CIN III and invasive carcinoma), compared with 82% for the Pap smear. Evaluation of lower grade neoplasms was also performed. Initial analyses of the data indicate that QFIA, which uses objective biochemical criteria to identify cells with increased nuclear nucleic acid content, is a more sensitive detector of cervical neoplasia of all grades than is conventional Pap cytology.

Hispanic adolescent conception and contraception profiles. A comparison.

Marital status, contraception, desire for pregnancy, and social support relationships were analyzed by ethnicity for a group of pregnant and postpartum adolescents. Although no significant differences were found among ethnic groups for birth control information and use, the desire for pregnancy, grouped by marital status at conception, was significantly different for Hispanics. Positive evaluations of the life changes associated with pregnancy were found more frequently among Hispanic mothers. Hispanic teen mothers, however, were least likely to understand the menstrual cycle. The role of ethnic background in adolescent fertility behaviour is discussed, and potential clinical applications for more effectively serving sexually active Hispanic adolescents are presented.

Perinatal market penetration rate. A tool to evaluate regional perinatal programs.

Very small babies born in tertiary centers fare better than outborn babies referred for tertiary care after birth. Viewing the 1001-1500 gm regional cohort of fetuses as a potential "market" for center delivery, and measuring a center's penetration into this market, quantitates how well a center draws to itself these small, high-risk fetuses for delivery. An Illinois center's annual penetration rate into its regional market for the years 1973-1983 is presented and significant increases are found. The penetration rates of nine Illinois perinatal centers are calculated and wide discrepancies are found. Defining a high-risk regional cohort as a market stresses a perinatal center's obligation to its region. The penetration rate into a defined market measures how well a center fulfills this obligation.

Health problems and sexual activity of selected inner city, middle school students.

Physical examinations were performed and health and sexual histories were taken on 496 12-14-year-old, inner city, middle school students participating in extracurricular activities. Health problems were identified in 9.5% of students. Twenty-one percent of a subgroup of 276 students reported sexual activity; males were three times as likely as females to report intercourse. More than one-half of a smaller subgroup named their parents as their primary source of information on sex. The value of the screening exam is discussed, and suggestions are offered on the content of preventive health and sex education curricula for this age group.

The incremental cost of screening, diagnosis, and treatment of gonorrhea and chlamydia in a family planning clinic.

A standard cost-finding methodology was used to estimate the incremental expenses associated with the provision of screening, diagnostic and treatment services for N. gonorrhoeae and Chlamydia trachomatis in a family planning clinic serving high risk adolescents. The study included both the personnel and nonpersonnel costs accrued in administering screening and diagnostic tests, contacting patients with infection, treating patients with infection, and administering tests of cure. The cost per screening test averaged $9.74 when part of a routine family planning visit. Diagnostic tests provided to drop-ins with symptoms averaged $19.92. Treatment-related costs per visit averaged $24.97. The total incremental cost of providing STD screening, diagnosis, and treatment services in the clinic represented 14% of the clinic's overall budget during the study period.
