Management of Vaginitis - Article
ABSTRACT: Common infectious forms of vaginitis include bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis. Vaginitis also can occur because of atrophic changes. Bacterial vaginosis is caused by proliferation of Gardnerella vaginalis, Mycoplasma hominis, and anaerobes. The diagnosis is based primarily on the Amsel criteria (milky discharge, pH greater than 4.5, positive whiff test, clue cells in a wet-mount preparation). The standard treatment is oral metronidazole in a dosage of 500 mg twice daily for seven days. Vulvovaginal candidiasis can be difficult to diagnose because characteristic signs and symptoms (thick, white discharge, dysuria, vulvovaginal pruritus and swelling) are not specific for the infection. Diagnosis should rely on microscopic examination of a sample from the lateral vaginal wall (10 to 20 percent potassium hydroxide preparation). Cultures are helpful in women with recurrent or complicated vulvovaginal candidiasis, because species other than Candida albicans (e.g., Candida glabrata, Candida tropicalis) may be present. Topical azole and oral fluconazole are equally efficacious in the management of uncomplicated vulvovaginal candidiasis, but a more extensive regimen may be required for complicated infections. Trichomoniasis may cause a foul-smelling, frothy discharge and, in most affected women, vaginal inflammatory changes. Culture and DNA probe testing are useful in diagnosing the infection; examinations of wet-mount preparations have a high false-negative rate. The standard treatment for trichomoniasis is a single 2-g oral dose of metronidazole. Atrophic vaginitis results from estrogen deficiency. Treatment with topical estrogen is effective.
Breast Cyst Aspiration - Article
ABSTRACT: The breast mass is a clinical problem commonly encountered by family physicians. Fine-needle and core biopsy techniques require training and cytopathologist support. In contrast, breast cyst aspiration using a 21- or 22-gauge needle is a simple, cost-effective, minimally invasive procedure. The technique is easy to learn and can be practiced on a breast model. Breast cyst aspiration may be attempted in many women who present with a palpable, dominant breast mass. If clear fluid is aspirated and the mass resolves, malignancy is unlikely, and breast cyst is the probable diagnosis. In this situation, reevaluation in four to six weeks is appropriate; if the cyst has not recurred, only routine mammographic surveillance is required. Referral for fine-needle or excisional biopsy is indicated if the aspirate is bloody or extremely tenacious, if no fluid can be aspirated, or if there is residual mass after aspiration. Complications such as local discomfort, bruising, and infection are uncommon.
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.
Management of Genital Warts - Article
ABSTRACT: Genital warts caused by human papillomavirus infection are encountered commonly in primary care. Evidence guiding treatment selection is limited, but treatment guidelines recently have changed. Biopsy, viral typing, acetowhite staining, and other diagnostic measures are not routinely required. The goal of treatment is clearance of visible warts; some evidence exists that treatment reduces infectivity, but there is no evidence that treatment reduces the incidence of cervical and genital cancer. The choice of therapy is based on the number, size, site, and morphology of lesions, as well as patient preferences, cost, convenience, adverse effects, and clinician experience. Patient-applied therapy such as imiquimod cream or podofilox is increasingly recommended. Podofilox, imiquimod, surgical excision, and cryotherapy are the most convenient and effective options. Fluorouracil and interferon are no longer recommended for routine use. The cost per successful treatment course is approximately dollars 200 to dollars 300 for podofilox, cryotherapy, electrodesiccation, surgical excision, laser treatment, and the loop electrosurgical excision procedure.
ABSTRACT: West Nile virus is a mosquito-borne flavivirus and human neuropathogen. Since the virus was recognized in New York City in 1999, it has spread rapidly across the United States, with human disease documented in 39 states and the District of Columbia. West Nile virus can cause a broad range of clinical syndromes, including fever, meningitis, encephalitis, and a flaccid paralysis characteristic of a poliomyelitis-like syndrome. Approximately one in 150 infections results in severe neurologic illness. Advanced age is the greatest risk factor for severe neurologic disease, long-term sequelae, and death. Physicians should consider West Nile virus infection when evaluating febrile patients who have unexplained neurologic symptoms, muscle weakness, or erythematous rash during late spring through early fall, or throughout the year in warm climates. West Nile virus infection has no characteristic findings on routine laboratory tests, although anemia, leukocytosis, or lymphopenia may be present. Testing for IgM antibody to West Nile virus in serum or cerebrospinal fluid (samples from the acute and convalescent phases, submitted at least two weeks apart) is the most common diagnostic method. Local or state health departments usually can perform the test within 24 to 36 hours of submission. Treatment is supportive. Prevention relies on comprehensive mosquito-control programs and measures to avoid mosquito bites, including the use of mosquito repellents containing N,N-diethyl-m-toluamide.
ABSTRACT: In February 2002, the Kidney Disease Outcome Quality Initiative of the National Kidney Foundation published clinical practice guidelines on chronic kidney disease. The first six of the 15 guidelines are of the greatest relevance to family physicians. Part I of this two-part article reviews guidelines 1, 2, and 3. Chronic kidney disease is defined by the presence of a marker of kidney damage, such as proteinuria (ratio of greater than 30 mg of albumin to 1 g of creatinine on untimed [spot] urine testing), or a decreased glomerular filtration rate for three or more months. Disease staging is based on the glomerular filtration rate. Evaluation should be directed at determining the type and severity of chronic kidney disease. Treatment goals include preventing disease progression and complications. The guidelines place special emphasis on the prevention and treatment of cardiovascular disease in patients with chronic kidney disease. Risk factors for chronic kidney disease include diabetes mellitus, hypertension, family history of chronic kidney disease, age older than 60 years, and U.S. racial or ethnic minority status. The guidelines recommend testing for proteinuria and estimating the glomerular filtration rate in patients at risk for chronic kidney disease. Family physicians should weigh the value of the National Kidney Foundation guidelines for their clinical practice based on the strength of evidence and perceived cost-effectiveness until additional evidence becomes available on the usefulness of the recommended quality indicators.
Diagnosis and Management of Preeclampsia - Article
ABSTRACT: Preeclampsia is a pregnancy-specific multisystem disorder of unknown etiology. The disorder affects approximately 5 to 7 percent of pregnancies and is a significant cause of maternal and fetal morbidity and mortality. Preeclampsia is defined by the new onset of elevated blood pressure and proteinuria after 20 weeks of gestation. It is considered severe if blood pressure and proteinuria are increased substantially or symptoms of end-organ damage (including fetal growth restriction) occur. There is no single reliable, cost-effective screening test for preeclampsia, and there are no well-established measures for primary prevention. Management before the onset of labor includes close monitoring of maternal and fetal status. Management during delivery includes seizure prophylaxis with magnesium sulfate and, if necessary, medical management of hypertension. Delivery remains the ultimate treatment. Access to prenatal care, early detection of the disorder, careful monitoring, and appropriate management are crucial elements in the prevention of preeclampsia-related deaths.
ABSTRACT: Despite increased scientific knowledge about asthma and improved therapeutic options, the disease continues to cause significant morbidity and mortality. The National Asthma Education and Prevention Program Expert Panel has updated its clinical guidelines on asthma medications, prevention of disease progression, and patient self-management. Diagnostic criteria have not changed, and identification of the disease relies on the physician's analysis of the patient's symptoms, family history, and spirometric measurements of lung function. Classification of asthma severity also has not changed, but many obstacles remain, including the variability of asthma and the classification system's inability to account for physical activity levels, which may result in significant underestimation of the severity of asthma. The National Asthma Education and Prevention Program recommends the use of written action plans with or without monitoring of peak expiratory flow, although evidence supporting these management techniques is inconclusive. Patients with asthma may benefit from earlier use of inhaled corticosteroids, which have been proven safe in the usual dosages. However, further studies are needed to determine whether inhaled corticosteroids can prevent the progression of asthma.
ABSTRACT: A detailed history alone may lead to a specific diagnosis in approximately 70 percent of patients who have wrist pain. Patients who present with spontaneous onset of wrist pain, who have a vague or distant history of trauma, or whose activities consist of repetitive loading could be suffering from a carpal bone nonunion or from avascular necrosis. The hand and wrist can be palpated to localize tenderness to a specific anatomic structure. Special tests can help support specific diagnoses (e.g., Finkelstein's test, the grind test, the lunotriquetral shear test, McMurray's test, the supination lift test, Watson's test). When radiography is indicated, the posterior-anterior and lateral views are essential to evaluate the bony architecture and alignment, the width and symmetry of the joint spaces, and the soft tissues. When the diagnosis remains unclear, or when the clinical course does not improve with conservative measures, further imaging modalities are indicated, including ultrasonography, technetium bone scan, computed tomography, and magnetic resonance imaging. If all studies are negative and clinically significant wrist pain continues, the patient may need to be referred to a specialist for further evaluation, which may include cineroentgenography, diagnostic arthrography, or arthroscopy.
Urinary Tract Infection in Children - Article
ABSTRACT: Up to 7 percent of girls and 2 percent of boys will have a symptomatic, culture-confirmed urinary tract infection by six years of age. Urinary tract infection may be suspected because of urinary symptoms in older children or because of fever, nonspecific symptoms, or failure to thrive in infants. Urine dipstick analysis is useful for ruling out urinary tract infections in cases with low clinical suspicion. However, urine culture is necessary for diagnosis of urinary tract infections in children if there is high clinical suspicion, cloudy urine, or if urine dipstick testing shows positive leukocyte esterase or nitrite activity. Despite current recommendations, routine imaging studies (e.g., renal ultrasonography, voiding cystourethrography, renal scans) do not appear to improve clinical outcomes in uncomplicated urinary tract infections. Oral antibiotics are as effective as parenteral therapy in randomized trials. The optimal duration of antibiotic therapy has not been established, but one-day therapies have been shown to be inferior to longer treatment courses.
