HIV Counseling, Testing, and Referral - Article
ABSTRACT: Over the past decade, the annual number of new cases of human immunodeficiency virus (HIV) infection has been relatively stable but remains unacceptably high (an estimated 40,000 new cases per year). Furthermore, the demographics for HIV infection are changing. Rates of new infections are declining in newborns, older men who have sex with men, and whites. However, rates of new infections are rising in young persons, women, Hispanics, and blacks. In 2001, the Centers for Disease Control and Prevention issued revised guidelines for HIV counseling, testing, and referral. The guidelines focus on the reduction of barriers to testing, voluntary routine testing of high-risk populations and persons with risk factors, case management and partner tracing for infected persons, and universal testing of pregnant women. Effective strategies for reducing HIV infection include behavioral interventions, comprehensive school-based HIV and sex education, access to sterile drug equipment, screening of the blood supply, and postexposure prophylaxis for health care workers.
ABSTRACT: Controversy surrounds the management options for localized prostate cancer-conservative management, prostatectomy, and radiation. Choosing among these options is difficult because of long-term side effects that include sexual, urinary, and bowel dysfunction. Some recent studies suggest that patients who have chosen treatment (i.e., radical prostatectomy or radiation) have longer disease-free survival compared with patients who have chosen conservative management (i.e., watchful waiting). However, several biases may artificially enhance the perceived value of treatment and make the interpretation of studies on treatment outcomes difficult. Sources of bias include lead time, length time, and patient selection. Because of the uncertain efficacy of management options and the risk of long-term treatment complications, family physicians need to engage their patients in the decision-making process.
ABSTRACT: The number one cause of death for children younger than 14 years is vehicular injury. Child safety seats and automobile safety belts protect children in a crash if they are used correctly, but if a child does not fit in the restraint correctly, it can lead to injury. A child safety seat should be used until the child correctly fits into an adult seat belt. It is important for physicians caring for children to know what child safety seats are available and which types of seats are safest. Three memory keys will help guide appropriate child safety seat choice: (1) Backwards is Best; (2) 20-40-80; and (3) Boost Until Big Enough. "Backwards is Best" cues the physician that infants are safest in a head-on crash when they are facing backward. "20-40-80" reminds the physician that children may need to transition to a different seat when they reach 20, 40, or 80 lb. "Boost Until Big Enough" emphasizes that children need to use booster seats until they are big enough to fit properly into an adult safety belt.
Genital Herpes: A Review - Article
ABSTRACT: Genital herpes simplex virus infection is a recurrent, lifelong disease with no cure. The strongest predictor for infection is a person's number of lifetime sex partners. The natural history includes first-episode mucocutaneous infection, establishment of latency in the dorsal root ganglion, and subsequent reactivation. Most infections are transmitted via asymptomatic viral shedding. Classic outbreaks consist of a skin prodrome and possible constitutional symptoms such as headache, fever, and inguinal lymphadenopathy. As the infection progresses, papules, vesicles on an erythematous base, and erosions appear over hours to days. These lesions usually crust, re-epithelialize, and heal without scarring. First-episode infections are more extensive: primary lesions last two to six weeks versus approximately one week for lesions in recurrent disease. Atypical manifestations are common. Infected persons experience a median of four recurrences per year after their first episode, but rates vary greatly. Genital herpes simplex virus type 2 recurs six times more frequently than type 1. Viral culture is preferred over polymerase chain reaction testing for diagnosis. Serologic testing can be useful in persons with a questionable history. Effective oral antiviral medications are available for initial, episodic, and suppressive therapy but are not a cure. There is some evidence that alternative therapies such as L-lysine, zinc, and some herbal preparations may offer some benefit. Counseling patients about the risk of transmission is crucial and helps prevent the spread of disease and neonatal complications.
ABSTRACT: Physicians face several barriers to counseling their patients about nutrition, including conflicting evidence of the benefit of counseling, limited training and understanding of the topic, and imperfect and varied guidelines to follow. Because cardiovascular disease remains the leading cause of death in industrialized nations, family physicians should provide more than pharmacologic interventions. They must identify the patient's dietary habits and attitudes and provide appropriate counseling. Tools are available to help, and a seven-step approach to nutritional therapy for the dyslipidemic patient may be useful. These steps include recommending increased intake of plant proteins; increased intake of omega-3 fatty acids; modification of the types of oils used in food preparation; decreased intake of saturated and trans-fatty acids; increased intake of whole grains and dietary fiber (especially soluble fiber) and decreased intake of refined grains; modification of alcohol intake, if needed; and regular exercise. Recommendations should be accompanied by patient information handouts presenting acceptable substitutions for currently identified detrimental food choices.
Second Trimester Pregnancy Loss - Article
ABSTRACT: Second trimester pregnancy loss is uncommon, but it should be regarded as an important event in a woman's obstetric history. Fetal abnormalities, including chromosomal problems, and maternal anatomic factors, immunologic factors, infection, and thrombophilia should be considered; however, a cause-and-effect relationship may be difficult to establish. A thorough history and physical examination should include inquiries about previous pregnancy loss. Laboratory tests may identify treatable etiologies. Although there is limited evidence that specific interventions improve outcomes, management of contributing maternal factors (e.g., smoking, substance abuse) is essential. Preventive measures, including vaccination and folic acid supplementation, are recommended regardless of risk. Management of associated chromosomal factors requires consultation with a genetic counselor or obstetrician. The family physician can play an important role in helping the patient and her family cope with the emotional aspects of pregnancy loss.
ABSTRACT: Substance abuse in adolescents is undertreated in the United States. Family physicians are well positioned to recognize substance use in their patients and to take steps to address the issue before use escalates. Comorbid mental disorders among adolescents with substance abuse include depression, anxiety, conduct disorder, and attention-deficit/ hyperactivity disorder. Office-, home-, and school-based drug testing is not routinely recommended. Screening tools for adolescent substance abuse include the CRAFFT questionnaire. Family therapy is crucial in the management of adolescent substance use disorders. Although family physicians may be able to treat adolescents with substance use disorders in the office setting, it is often necessary and prudent to refer patients to one or more appropriate consultants who specialize specifically in substance use disorders, psychology, or psychiatry. Treatment options include anticipatory guidance, brief therapeutic counseling, school-based drug-counseling programs, outpatient substance abuse clinics, day treatment programs, and inpatient and residential programs. Working within community and family contexts, family physicians can activate and oversee the system of professionals and treatment components necessary for optimal management of substance misuse in adolescents.
Initial Counseling of Children with Eating Disorders and Their Families - Curbside Consultation
Reducing Tobacco Use in Adolescents - Article
ABSTRACT: After steadily decreasing since the late 1990s, adolescent smoking rates have stabilized at levels well above national goals. Experts recommend screening for tobacco use and exposure at every patient visit, although evidence of improved outcomes in adolescents is lacking. Counseling should be provided using the 5-A method (ask, advise, assess, assist, and arrange). All smokers should be offered smoking cessation assistance, including counseling, nicotine replacement therapy, bupropion therapy, or combination therapy. Pharmacotherapy of any kind doubles the likelihood of successful smoking cessation in adults; however, nicotine replacement therapy is the only pharmacologic intervention that has been extensively studied in children. Community interventions such as smoking bans and educational programs have been effective at reducing smoking rates in children and adolescents. Antismoking advertising and tobacco sales taxes also help deter new smokers and motivate current smokers to attempt to quit.
Physical Activity Counseling - Article
ABSTRACT: Every year in the United States, at least 250,000 deaths are attributed to lack of physical activity. Because of the health benefits of physical activity, national guidelines recommend participation in 30 minutes of accumulated moderate-intensity physical activity such as walking fast on five or more days of the week. However, most Americans fail to achieve this goal and report that their physicians have not counseled them to increase physical activity. Because 84 percent of Americans consult a physician each year, even brief physician counseling that leads to modest activity changes could affect the population's health. Some physicians report that they do not deliver physical activity counseling because of limitations in time, reimbursement, knowledge, confidence, and practical tools. The five A's (Assess, Advise, Agree, Assist, Arrange) model can help physicians deliver brief, individually tailored physical activity messages to patients.
