摘要:

The decline in adolescent pregnancy rates noted in the 1990s has been attributed to more teenagers choosing abstinence, the availability of long-acting contraceptive options, and the increased use of condoms. Many adolescents remain at risk of unplanned pregnancy, however, because of method failure, inconsistent or incorrect use, or discontinuation of a method without choosing another method. Practitioners who care for adolescents and young women have access to several new methods in 2003. Recent additions include a contraceptive transdermal patch, a hormone-releasing intravaginal ring, new formulations of pills, and a new intrauterine device. Additionally, the World Health Organization has updated its guidelines to provide the practitioner with evidence-based recommendations to assist in selecting the most appropriate contraceptive method for each patient.

摘要:

Long-term hypertension contributes to significant cardiovascular and renal morbidity and mortality. Although chronic hypertension is much rarer in the adolescent population than in adults, identifying the hypertensive adolescent and intervening with risk factors such as obesity that may promote hypertension is important for the clinician treating adolescents. Since both primary and secondary causes of hypertension may exist in the adolescent, a thorough and sequential clinical and diagnostic evaluation must be undertaken, including screening urinalysis, blood chemistries, and renal sonography. There are pitfalls in interpreting casual blood pressure measurements in adolescents, and the role of ambulatory blood pressure monitoring is evolving. Lifestyle modifications, including diet, exercise, and limitation of sodium intake, remain the foundation of treatment. Commonly used medications include calcium channel blockers, angiotensin receptor blockers and converting enzyme inhibitors, beta blockers, and diuretics. When considering medication in the hypertensive adolescent, potential complications of therapy must be reviewed in light of the physical and psychosocial changes ongoing in this age group.

摘要:

Postexposure prophylaxis is an effective intervention to prevent transmission of the human immunodeficiency virus (HIV). Administration of antiretroviral medications within 72 hours of a percutaneous or mucous membrane exposure to HIV can prevent infection. The use of postexposure prophylaxis for occupational and perinatal HIV exposures is well established. Its efficacy for nonoccupational exposures has only recently been studied. To date in the United States, there are no national guidelines regarding postexposure prophylaxis for nonoccupational exposures. Decisions regarding its use should be made after weighing the risks of seroconversion for a given exposure, the risks of HIV in the source, and the potential toxicities of the antiretroviral medications. Several state guidelines may also serve as important resources. Clinicians should consider initiating postexposure prophylaxis in adolescents for any oral, anal, or vaginal exposure to definitely or possibly HIV-infected blood or body fluids. Adolescents treated should be followed closely for medication toxicity, acute seroconversion, and risk-reduction counseling. Further studies are needed to characterize the use and efficacy of postexposure prophylaxis in an adolescent population.

摘要:

Increasing levels of stress in the daily lives of adolescents is an important health concern. Adolescents experience a variety of stressful situations and use a wide range of coping strategies to help effectively manage stress. Recent research on adolescent coping with stressful situations is reviewed. Findings support an association between coping and adolescent health problems, chronic physical illness, and mental health. More research is needed to investigate the long-term benefits of coping with stress on adolescent health and well-being. Specific recommendations for helping adolescents cope with stressful situations are discussed. Health care providers are encouraged to assess how adolescents cope with acute and chronic stressors and provide adolescents with information about coping with stressful situations.

摘要:

Sexually transmitted diseases (STDs) are a major health problem for adolescents. Health care providers for adolescents play a critical role in preventing and treating STDs. In May 2002, the Centers for Disease Control and Prevention published theSexually Transmitted Diseases Treatment Guidelines 2002.These evidence-based guidelines are based on a systematic literature review focusing on information that had become available since the1998 Guidelines for Treatment of STDs.This article reviews the new STD treatment guidelines for gonorrhea, chlamydia, bacterial vaginosis, trichomonas, vulvovaginal candidiasis, pelvic inflammatory disease, genital warts, herpes simplex virus infection, syphilis, and scabies. Although these guidelines emphasize treatment, prevention strategies and diagnostic recommendations also are discussed.

摘要:

Purpose of reviewAtopic dermatitis is a chronic inflammatory skin disease commonly seen in children, but it also occurs in adults. This skin disease is often triggered by bacterial, fungal, or viral skin infections. The mechanisms resulting in this increased propensity for skin infections have been an area of active investigation.Recent findingsRecent studies suggest that the skin of patients with atopic dermatitis has increased avidity for binding toStaphylococcus aureusand is deficient in its ability to generate antimicrobial peptides needed to eradicate infectious agents.SummaryThe current review will examine recent literature on the etiology and pathogenesis of infection in atopic dermatitis. These observations are likely to have importance implications for management of atopic dermatitis.

摘要:

Acne vulgaris is a common cutaneous disorder of the pilosebaceous follicle. More than 45 million people are affected with acne vulgaris. In addition, 80% of people in the United States report that they suffered from acne at one point in life. It is estimated that US consumers spend $1.2 billion each year for the treatment of acne. Typically, lesions are pleomorphic and range from open and closed comedones to inflammatory papules, pustules, cysts, and nodules, and scarring may result. The disease is important, with a significant effect on patients' self-esteem. The pathogenesis is only partially understood and is multifactorial. Successful management of acne requires an understanding of the pathophysiology of disease. The first half of this review discusses new discoveries in the pathogenesis of acne, and the second half introduces new and time-honored therapies.

摘要:

Type 2 diabetes mellitus in the pediatric population is now a public health problem. It represents 8 to 45% of all diabetes reported among children and adolescents. Concurrently, childhood obesity has become an epidemic in the United States. Epidemiologic risk factors and diagnostic criteria have largely been established: The incidence of type 2 diabetes increases with age and obesity. Children and adolescents diagnosed with type 2 diabetes usually have a first- or second-degree relative with the disorder. Familial clustering and twin studies have suggested a genetic component for type 2 diabetes. However, the molecular mechanisms that promote diabetes in susceptible individuals, the best treatment plans, and methods of prevention of this disorder are not yet established.
