Management of active tuberculosis.

Although the overall incidence of tuberculosis has been declining in the United States, it remains an important public health concern, particularly among immigrants, homeless persons, and persons infected with human immunodeficiency virus. Patients who present with symptoms of active tuberculosis (e.g., cough, weight loss, or malaise with known exposure to the disease) should be evaluated. Three induced sputum samples for acid-fast bacillus smear and culture should be obtained from patients with findings of tuberculosis or suspicion for active disease. If the patient has manifestations of extrapulmonary tuberculosis, smears and cultures should be obtained from these sites. Most patients with active tuberculosis should be treated initially with isoniazid, rifampin, pyrazinamide, and ethambutol for eight weeks, followed by 18 weeks of treatment with isoniazid and rifampin if needed. Repeat cultures should be performed after the initial eight-week treatment.

Diagnosis and management of ectopic pregnancy.

Ectopic pregnancy is a high-risk condition that occurs in 1.9 percent of reported pregnancies. The condition is the leading cause of pregnancy-related death in the first trimester. If a woman of reproductive age presents with abdominal pain, vaginal bleeding, syncope, or hypotension, the physician should perform a pregnancy test. If the patient is pregnant, the physician should perform a work-up to detect possible ectopic or ruptured ectopic pregnancy. Prompt ultrasound evaluation is key in diagnosing ectopic pregnancy. Equivocal ultrasound results should be combined with quantitative beta subunit of human chorionic gonadotropin levels. If a patient has a beta subunit of human chorionic gonadotropin level of 1,500 mIU per mL or greater, but the transvaginal ultrasonography does not show an intrauterine gestational sac, ectopic pregnancy should be suspected. Diagnostic uterine curettage may be appropriate in patients who are hemodynamically stable and whose beta subunit of human chorionic gonadotropin levels are not increasing as expected. Appropriate treatment for patients with nonruptured ectopic pregnancy may include expectant management, medical management with methotrexate, or surgery. Expectant management is appropriate only when beta subunit of human chorionic gonadotropin levels are low and declining. Initial levels determine the success of medical treatment. Surgical treatment is appropriate if ruptured ectopic pregnancy is suspected and if the patient is hemodynamically unstable.

Obstetrics and gynecology resident education in tobacco, alcohol, and drug use disorders.

Substance use disorders are common problems that all primary care physicians will encounter. These disorders have a significant impact on the health of all affected women throughout their lifespan. It is important to know the effects of drug use on women, so primary care residents need to be prepared to discuss substance use disorders with their patients. Residents also need to know that brief interventions can reduce risky behaviors even if they do not result in abstinence.
