Effectiveness of a high school smoking cessation program.
OBJECTIVE: To evaluate the impact of a school-based smoking cessation program targeting adolescents interested in quitting. DESIGN: Randomized clinical trial over one school year. SETTING: Large public high school. PARTICIPANTS: Students interested in quitting smoking. INTERVENTION: Seventy-four students were randomized to receive either: 1) a 6-week, 8-session, classroom-based, smoking cessation curriculum designed for adolescents (n = 35) or 2) an informational pamphlet on how to quit smoking with promise of the classroom curriculum in 3 months (n = 39). OUTCOME MEASURES: Change in smoking behavior measured by: 1) self-reported smoking cessation and exhaled carbon monoxide <6 parts per million (smoke-free); 2) self-reported quit attempts; and 3) change in cigarettes per day (cpd) at the end of the 6-week curriculum and then 4, 10, and 20 weeks later. Saliva cotinine was also measured at these points to validate these outcome measures. Analysis. Intention-to-treat. RESULTS: Participants in the classroom group attended an average of 4.4 sessions. At the end of the curriculum, the classroom group was significantly more likely to be smoke-free (59% vs 17%), to have tried to quit smoking (82% vs 54%), and to reduce mean cpd (7.0 vs 1.0). Four weeks later, these differences persisted: smoke-free (52% vs 20%), quit attempt (85% vs 60%), and reduction in mean cpd (6.6 vs 1.6). Changes in saliva cotinine were consistent with reported outcome measures; those who were smoke-free had a significant reduction in saliva cotinine at the end of the intervention, and at 4 weeks. At 10 and 20 weeks after the curriculum, 41% and 31%, respectively, of the classroom group remained smoke-free. Once participants in the pamphlet group underwent the classroom intervention (average attendance of 2.2 sessions) their cessation rates were similar to the initial group: 31% at the end of the curriculum and 27% 10 weeks later. CONCLUSION: A school-based curriculum for adolescent smoking cessation is more effective than an informational pamphlet alone and reduces cigarette use by adolescents. More research is needed to test the reproducibility, sustainability, and generalizability of this curriculum to offer more smoking cessation options to teenagers.

Tobacco use among high school students in Buenos Aires, Argentina.
OBJECTIVES: This study assessed the prevalence and correlates of tobacco use among high school students in Buenos Aires, Argentina. METHODS: Anonymous, self-administered questionnaires were given to 3909 8th and 11th graders in a stratified random sample of 49 public and private schools. The instrument included items from American surveys, translated and validated among Argentinean teens. Multiple logistic regression analysis was used to estimate possible effects on smoking behavior of environment, students' personal characteristics, and their knowledge, beliefs, and attitudes regarding smoking. RESULTS: Of 8th and 11th graders, 20% and 43%, respectively, were classified as current smokers. Overall, 29% of males and 32% of females were current smokers. Students attending public schools were more likely to smoke than those in private schools (P < .05). Current smoking was associated with having a best friend who smokes, reporting that more than 50% of friends of the same sex smoke, having positive attitudes and beliefs toward smoking, and having a positive intention to smoke within the next year (all P < .001). CONCLUSIONS: Over 20% of the 8th graders in our sample were current smokers; prevention efforts must therefore start early.

Why adolescent medicine?
This article reviews the biologic, cognitive, and sociocultural changes that occur during adolescence. Providing appropriate health care to adolescents in an effective manner requires an in-depth understanding of these changes, both in terms of preventing the onset of health-risking behaviors and promoting a healthy lifestyle. As many chronic diseases of adults have their origins during adolescence, this approach holds promise for reducing morbidity and mortality in later life as well as during young adulthood. There is an emerging consensus regarding the scope and content of preventive services for adolescents. The approach to incorporating these services into the health maintenance visit for young people is reviewed.

Use of spun urine to enhance detection of Trichomonas vaginalis in adolescent women.
BACKGROUND: Diagnosis of Trichomonas vaginalis infection is traditionally performed by microscopic examination of vaginal fluid. Although this technique is relatively insensitive compared with culture, it is widely used because of its lower cost and immediate results. OBJECTIVE: To assess the utility of microscopic examination of spun urine as a means of increasing the sensitivity of microscopic diagnosis of T. vaginalis. DESIGN AND SETTING: Retrospective observational study performed in a hospital-based adolescent clinic. SUBJECTS: Female patients enrolled between July 1995 and August 1996 into a larger study evaluating diagnosis of vaginal infections (N = 686). To be included, subjects had to have a positive culture for T. vaginalis (n = 97); those who did not have a spun urine examination were excluded (n = 22). MAIN OUTCOME MEASURE: Microscopic examination of vaginal fluid and spun urine for presence of motile trichomonads. Using a positive Trichomonas culture as the reference standard, the sensitivity of vaginal fluid alone was compared with vaginal fluid plus spun urine. The McNemar test for paired samples was used to test the statistical significance of the difference in sensitivities. RESULTS: Ninety-seven subjects had culture results positive for Trichomonas. Of these, 75 (77%) had a spun urine examination performed. Subjects were aged 13 to 22 years and all were African American. Seventy-three percent of the infections were detected by vaginal fluid specimen, 64% by spun urine, and 85% by either vaginal specimen or spun urine. The difference in sensitivity between vaginal specimen alone and vaginal specimen plus spun urine was 12% (95% confidence interval, 3%-21%; P<.005). Nine patients who would not have been diagnosed by examination of vaginal fluid alone were diagnosed with the addition of spun urine examination. CONCLUSION: Microscopic examination of a spun urine specimen performed in conjunction with microscopic examination of a vaginal fluid specimen improves the detection rate of T. vaginalis.

Screening, early identification, and office-based intervention with children and youth living in substance-abusing families.
All health care professionals with clinical responsibility for the care of children and adolescents must be able to recognize, as early as possible, associated health problems or concerns in children of substance-abusing parents, and to be able to assist these children and families in seeking treatment and promoting health. Health care providers can have a tremendous influence on families of substance-abusing parents because of their understanding of family dynamics and their close long-standing relationship with the family. Information about family alcohol and other drug use should be obtained as part of routine history-taking and when there are indications of family dysfunction, child behavior or emotional problems, school difficulties, and recurring episodes of apparent accidental trauma, and in the setting of recurrent or multiple vague somatic complaints by the child or adolescent. In many instances, family problems with alcohol or drug use are not blatant; rather, their identification requires a deliberate and skilled screening effort. Combining the principles of anticipatory guidance, screening, and early identification, with the acknowledgment that families should be included in the process, leads to a clear conclusion that screening for children affected by parental substance abuse must occur at all ages across infancy, childhood, and adolescence. Health care providers need to be trained in the identification and management of children and youth exposed to parental addiction. Such training must begin during undergraduate education in the health professions and be reinforced by role-modeling among health professions faculty as well as practicing providers.

American Academy of Pediatrics. Committee on Substance Abuse. Marijuana: A continuing concern for pediatricians.
Marijuana, the common name for products derived from the plant Cannabis sativa, is the most common illicit drug used by children and adolescents in the United States.(1) Despite growing concerns by the medical profession about the physical and psychological effects of its active ingredient, Delta-9-tetrahydrocannabinol, survey data continue to show that increasing numbers of young people are using the drug as they become less concerned about its dangers.(1)

Screening for gonorrhea and chlamydia by DNA amplification in adolescents attending middle school health centers. Opportunity for early intervention.
GOAL: To determine prevalence and incidence of Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) infection and assess risk factors predictive for such infections in a middle school-based clinic sample. STUDY DESIGN: 170 female students and 43 male students making 256 and 47 visits, respectively, > or = 30 days apart, in urban middle school clinics for primary care screening, reproductive health, or illness/injury were routinely asked to provide urine specimens for GC and CT ligase chain reaction testing if sexually active in the preceding 3-month period. Information regarding prior sexually transmitted diseases, reason for visit, and sexual risk behaviors was obtained. RESULTS: GC: 11.4% of female student and 2.1% of male student tests were positive. Incidence was 34.0 cases/1,000 person months (95% Confidence interval [CI]: 19.5-67.5). Median time to first positive and repeat positive test was 4.6 and 2.6 months, respectively. For CT: 16.4% of female student and 2.1% of male student tests were positive. Incidence was 57.5 cases/1,000 person months (95% CI: 35.2-93.8). Median time to first positive and repeat positive CT test was 6.0 and 4.8 months, respectively. Assessed risk factors failed to specify a candidate screening population. CONCLUSION: These data suggest that all sexually active adolescent girls in this high risk setting should be offered testing for GC and CT at least twice per year, regardless of age or other sexual risk behaviors and that STD control efforts in high risk middle schools should be encouraged.

Evaluation of vaginal infections in adolescent women: can it be done without a speculum?
OBJECTIVE: Given that highly sensitive urine-based nucleic acid amplification tests may eliminate the need for speculum exam to diagnose gonorrhea and chlamydia cervicitis, we sought to determine if vaginal infections could be diagnosed without using a speculum. METHODS: Matched pairs of vaginal specimens were collected from participants before and during speculum exam for diagnosis of trichomoniasis, bacterial vaginosis, and vulvovaginal candidiasis. Females age 12 to 22 years presenting to the Johns Hopkins adolescent primary care clinics who required a pelvic examination were eligible to participate. A convenience sample of 686 patients was recruited between July 1995 and August 1996. Paired vaginal specimens were evaluated with blinded microscopic evaluation. Analysis consisted of: 1) comparison of collection method sensitivities; and 2) assessment of proportions of infections detected by one method that were also detected by the other method. RESULTS: Sensitivities of speculum and nonspeculum collection methods were 75% and 77% (difference = -2%; 95% confidence interval, -11%, 7%) for trichomoniasis, 64% and 68% (difference = -4% [-10%, 3%]) for bacterial vaginosis, and 85% and 80% (difference = 5% [-12%, 22%]) for vulvovaginal candidiasis. The speculum method identified 88% (trichomoniasis), 90% (bacterial vaginosis), and 81% (vulvovaginal candidiasis) of infections detected by the nonspeculum method. The nonspeculum method identified 91% (trichomoniasis), 95% (bacterial vaginosis), and 76% (vulvovaginal candidiasis) of infections detected by the speculum method. CONCLUSIONS: Vaginal infections can be adequately diagnosed without a speculum. Once urine-based diagnosis of gonorrhea and chlamydia becomes well established, it may be possible to perform evaluations for uncomplicated genitourinary complaints without using a speculum.

Residents' self-assessed skills in providing sexuality-related care to teenagers.
OBJECTIVES: To assess pediatric residents' self-reported skills and satisfaction with providing sexuality-related health care to teenagers and to examine differences by resident and patient gender. DESIGN: Cross-sectional survey. PARTICIPANTS: Forty second-year (PGY2) and 17 third-year (PGY3) pediatric residents at one training program who completed a self-administered questionnaire. MAIN OUTCOME MEASURES: Residents rated their skills with taking a history from, performing a physical examination on, developing a diagnosis for, and counseling both male and female teenagers. Skills with providing health care to male and female teenagers were assessed separately. Scales were constructed for skills with performing a physical examination and providing a diagnosis and counseling. Residents also rated their satisfaction with providing health care to male and female teenagers. Skills and satisfaction with providing health care to male vs female teenagers were analyzed. RESULTS: Female residents rated their skills with providing health care to male teenagers significantly lower than their skills with providing health care to female teenagers as follows: taking a history of pubertal development (PGY2, P = .001; PGY3, P = .02), taking a sexual history (PGY2, P = .004), asking about sexual preference (PGY2, P = .02), examination and diagnosis scale (PGY2, P < .001; PGY3, P = .008), and counseling scale (PGY2, P = .003). For male residents, there were no significant differences in skills with providing health care to male vs female teenagers. Second-year, but not third-year, female residents reported significantly lower (P < .005) satisfaction with providing health care to male vs female teenagers. CONCLUSIONS: Among female residents, discrepancies were found when comparing self-assessed competencies and, for PGY2 residents, level of satisfaction with providing health care to male vs female patients. If other research confirms these findings, educational interventions related to sexuality-related health care for teenagers should be designed with consideration to gender-specific learner needs.

Recurrent toxic delirium in a patient treated with SSRIs: is old age a risk factor?
We present the case of a 71-year-old female suffering from bipolar affective disorder type 2 and an old lacunar brain infarct who, under the combined treatment of fluoxetine for depression and low dose trazodone for the accompanying insomnia, developed a toxic delirium. The subject presented with mental state changes (confusion and agitation), hyperreflexia, diaphoresis, nausea, vomiting, fever, and a general tonic-clonic seizure which developed soon after an increase in the trazodone dose. One year prior to the above episode, she was hospitalized for a transient episode of agitated confusion while being treated with fluvoxamine for depression, alprazolam and brotazolam for the accompanying anxiety and insomnia. Both episodes subsided spontaneously when treatment was discontinued. This case reports the possible existence of increased vulnerability to hyperserotonergic states in elderly patients suffering from concomitant psychiatric and neurological disorders.

Randomised study of cognitive effects of iron supplementation in non-anaemic iron-deficient adolescent girls.
BACKGROUND: Up to 25% of adolescent girls in the USA are iron deficient. This double-blind, placebo-controlled clinical trial assessed the effects of iron supplementation on cognitive function in adolescent girls with non-anaemic iron deficiency. METHODS: 716 girls who enrolled at four Baltimore high schools were screened for non-anaemic iron deficiency (serum ferritin < or = 12 micrograms/L with normal haemoglobin). 98 (13.7%) girls had non-anaemic iron deficiency of whom 81 were enrolled in the trial. Participants were randomly assigned oral ferrous sulphate (650 mg twice daily) or placebo for 8 weeks. The effect of iron treatment was assessed by questionnaires and haematological and cognitive tests, which were done before treatment started and repeated after the intervention. We used four tests of attention and memory to measure cognitive functioning. Intention-to-treat and per-protocol analyses were done. FINDINGS: Of the 81 enrolled girls with non-anaemic iron deficiency, 78 (96%) completed the study (39 in each group). Five girls (three control, two treatment) developed anaemia during the intervention and were excluded from the analyses. Thus, 73 girls were included in the per-protocol analysis. Ethnic distribution, mean age, serum ferritin concentrations, haemoglobin concentrations, and cognitive test scores of the groups did not differ significantly at baseline. Postintervention haematological measures of iron status were significantly improved in the treatment group (serum ferritin 27.3 vs 12.1 micrograms/L, p < 0.001). Regression analysis showed that girls who received iron performed better on a test of verbal learning and memory than girls in the control group (p < 0.02). INTERPRETATION: In this urban population of non-anaemic iron-deficient adolescent girls, iron supplementation improved verbal learning and memory.

Depressive symptoms, stress, and social support in pregnant and postpartum adolescents.
OBJECTIVE: To assess prospectively the incidence and course of depressive symptoms among pregnant and postpartum adolescents and explore the roles of stress and social support as influencing factors. METHODS: Pregnant teenagers attending a comprehensive adolescent pregnancy and parenting program were enrolled during their third trimester of pregnancy and followed up through 4 months post partum. Depressive symptoms and social support were measured with validated, self-administered instruments during the third trimester and at 2 and 4 months post partum. Stress was measured during the prenatal and postpartum periods. RESULTS: Study participants (N=125) were predominantly black (93%), and wee aged 12 to 18 years. Completed assessments were obtained from 114 subjects at 2 months post partum and 108 at 4 months. Forty-two percent had significant depressive symptoms in the third trimester, with 36% and 32% having scores that indicated depression at 2 and 4 months post partum. Stress levels increased significantly from the third trimester to the postpartum period (P < .01) and were positively associated with depressive symptoms. Receiving social support from the adolescent's mother or the infant's father, especially in the postpartum period, was significantly associated with lower rates of depression. Reporting conflict with the infant's father was strongly associated with increased rates of depressive symptoms. CONCLUSIONS: Results indicate that depressive symptoms are common among pregnant teenagers and postpartum adolescents. Stress and social support appear to be important mediators. Identifying those teenagers with high stress and conflict and low levels of support will help identify those who are at particular risk for depressive symptoms.

Evaluation of pulmonary function and polysomnography in obese children and adolescents.
Obese adults have an increased prevalence of pulmonary disorders. Although childhood obesity is a common problem, few studies have evaluated the pulmonary complications of obesity in the pediatric population. We, therefore, performed pulmonary function tests (PFTs), polysomnography, and multiple sleep latency tests (MSLTs) in 22 obese children and adolescents [mean age, 10 +/- 5 (SD) years; 73 percent female; 184 +/- 36 percent ideal body weight], none of whom presented because of sleep or respiratory complaints. PFTs were normal in all but two subjects. Ten (46 percent) subjects had abnormal polysomnograms. There was a positive correlation between the degree of obesity and the apnea index (r = 0.47, P < 0.05), and an inverse correlation between the degree of obesity and the Sa0(2) nadir (r = -0.60, P < 0.01). The degree of sleepiness on MSLT correlated with the degree of obesity (r = -0.50, P < 0.05). We conclude that obese children and adolescents have a high prevalence of sleep-disordered breathing, although in many cases it is mild. Obstructive sleep apnea syndrome (OSAS) improved following tonsillectomy and adenoidectomy. We recommend that pediatricians have a high index of suspicion for OSAS when evaluating obese patients, and that polysomnography be considered for these patients.
