Screening for Hearing Loss in Older Adults - Putting Prevention into Practice
ABSTRACT: Iron deficiency is the most common nutritional disorder worldwide and accounts for approximately one-half of anemia cases. The diagnosis of iron deficiency anemia is confirmed by the findings of low iron stores and a hemoglobin level two standard deviations below normal. Women should be screened during pregnancy, and children screened at one year of age. Supplemental iron may be given initially, followed by further workup if the patient is not responsive to therapy. Men and postmenopausal women should not be screened, but should be evaluated with gastrointestinal endoscopy if diagnosed with iron deficiency anemia. The underlying cause should be treated, and oral iron therapy can be initiated to replenish iron stores. Parenteral therapy may be used in patients who cannot tolerate or absorb oral preparations.
ABSTRACT: Chlamydia trachomatis is a gram-negative bacterium that infects the columnar epithelium of the cervix, urethra, and rectum, as well as nongenital sites such as the lungs and eyes. The bacterium is the cause of the most frequently reported sexually transmitted disease in the United States, which is responsible for more than 1 million infections annually. Most persons with this infection are asymptomatic. Untreated infection can result in serious complications such as pelvic inflammatory disease, infertility, and ectopic pregnancy in women, and epididymitis and orchitis in men. Men and women can experience chlamydia-induced reactive arthritis. Treatment of uncomplicated cases should include azithromycin or doxycycline. Screening is recommended in all women younger than 25 years, in all pregnant women, and in women who are at increased risk of infection. Screening is not currently recommended in men. In neonates and infants, the bacterium can cause conjunctivitis and pneumonia. Adults may also experience conjunctivitis caused by chlamydia. Trachoma is a recurrent ocular infection caused by chlamydia and is endemic in the developing world.
ABSTRACT: Serious health problems, risky behavior, and poor health habits persist among adolescents despite access to medical care. Most adolescents do not seek advice about preventing leading causes of morbidity and mortality in their age group, and physicians often do not find ways to provide it. Although helping adolescents prevent unintended pregnancy, sexually transmitted infections, unintentional injuries, depression, suicide, and other problems is a community-wide effort, primary care physicians are well situated to discuss risks and offer interventions. Evidence supports routinely screening for obesity and depression, offering testing for human immunodeficiency virus infection, and screening for other sexually transmitted infections in some adolescents. Evidence validating the effectiveness of physician counseling about unintended pregnancy, gang violence, and substance abuse is scant. However, physicians should use empathic, personal messages to communicate with adolescents about these issues until studies prove the benefits of more specific methods. Effective communication with adolescents requires seeing the patient alone, tailoring the discussion to the individual patient, and understanding the role of the parents and of confidentiality.
ABSTRACT: Peripheral arterial disease (PAD) is atherosclerosis leading to narrowing of the major arteries distal to the aortic arch. The most common presenting symptom is claudication; however, only 10% of patients have classic claudication. Approximately 8 to 12 million Americans have PAD, including 15% to 20% of adults older than 70 years. The ankle-brachial index (ABI) can be used to screen for and diagnose PAD in the primary care setting. An ABI of less than 0.9 is associated with a two- to fourfold increase in relative risk for cardiovascular events and all-cause mortality. To improve cardiovascular risk stratification and risk factor modification, the American Diabetes Association recommends ABI screening for patients older than 50 years who have diabetes mellitus, and the American Heart Association recommends screening all patients 65 years and older and those 50 years and older who have a history of diabetes or smoking. Because there is no evidence that screening leads to fewer cardiovascular events or lower all-cause mortality, the U.S. Preventive Services Task Force recommends against screening for PAD. Management of claudication includes exercise, smoking cessation, statin therapy, and antiplatelet therapy with aspirin or clopidogrel, and possibly cilostazol in patients with no history of heart failure. Surgical revascularization may be considered in patients with lifestyle-limiting claudication symptoms that do not respond to medical therapy.
