ABSTRACT: Spurred by mounting evidence that the detection and treatment of early-stage colorectal cancers and adenomatous polyps can reduce mortality, Medicare and some other payors recently authorized reimbursement for colorectal cancer screening in persons at average risk for this malignancy. A collaborative group of experts convened by the U.S. Agency for Health Care Policy and Research has recommended screening for average-risk persons over the age of 50 years using one of the following techniques: fecal occult blood testing each year, flexible sigmoidoscopy every five years, fecal occult blood testing every year combined with flexible sigmoidoscopy every five years, double-contrast barium enema every five to 10 years or colonoscopy every 10 years. Screening of persons with risk factors should begin at an earlier age, depending on the family history of colorectal cancer or polyps. These recommendations augment the colorectal cancer screening guidelines of the American Academy of Family physicians. Recent advances in genetic research have made it possible to identify persons at high risk for colorectal cancer because of an inherited predisposition to develop this malignancy. These patients require aggressive screening, usually by lower endoscopy performed at an early age. In some patients, genetic testing can guide screening and may be cost-effective.
Endometrial Cancer - Article
ABSTRACT: Endometrial cancer is the fourth most common cancer in women, accounting for approximately 6,000 deaths per year in the United States. It is more common in women who are older, white, affluent obese and of low parity. Hypertension and diabetes mellitus are also predisposing factors. Because any condition that increases exposure to unopposed estrogen increases the risk of endometrial cancer, tamoxifen therapy, estrogen replacement therapy without progestin and the presence of estrogen-secreting tumors are all risk factors. Smoking and the use of oral contraceptives appear to decrease the risk. Women with an increased risk and those with postmenopausal bleeding should be screened for endometrial cancer. Endometrial sampling is currently the most accurate and widely used screening technique, but ultrasonographic measurement of endometrial thickness and hysteroscopy have also been studied. Patients with endometrial specimens that show atypia have about a 25 percent likelihood of progressing to carcinoma, compared with less than 2 percent in patients without atypia. Endometrial cancer is usually treated surgically, but in patients with appropriate pathologic findings who decline surgical treatment, progestin therapy may be satisfactory.

ABSTRACT: Atopic dermatitis is a common, potentially debilitating condition that can compromise quality of life. Its most frequent symptom is pruritus. Attempts to relieve the itch by scratching simply worsen the rash, creating a vicious circle. Treatment should be directed at limiting itching, repairing the skin and decreasing inflammation when necessary. Lubricants, antihistamines and topical corticosteroids are the mainstays of therapy. When required, oral corticosteroids can be used. If pruritus does not respond to treatment, other diagnoses, such as bacterial overgrowth or viral infections, should be considered. Treatment options are available for refractory atopic dermatitis, but these measures should be reserved for use in unique situations and typically require consultation with a dermatologist or an allergist.
Evaluation and Management of Dyspepsia - Article
ABSTRACT: Dyspepsia, often defined as chronic or recurrent discomfort centered in the upper abdomen, can be caused by a variety of conditions. Common etiologies include peptic ulcers and gastroesophageal reflux. Serious causes, such as gastric and pancreatic cancers, are rare but must also be considered. Symptoms of possible causes often overlap, which can make initial diagnosis difficult. In many patients, a definite cause is never established. The initial evaluation of patients with dyspepsia includes a thorough history and physical examination, with special attention given to elements that suggest the presence of serious disease. Endoscopy should be performed promptly in patients who have "alarm symptoms" such as melena or anorexia. Optimal management remains controversial in young patients who do not have alarm symptoms. Although management should be individualized, a cost-effective initial approach is to test for Helicobacter pylori and treat the infection if the test is positive. If the H. pylori test is negative, empiric therapy with a gastric acid suppressant or prokinetic agent is recommended. If symptoms persist or recur after six to eight weeks of empiric therapy, endoscopy should be performed.
ABSTRACT: Family physicians often encounter patients with acute knee trauma. Radiographs of injured knees are commonly ordered, even though fractures are found in only 6 percent of such patients and emergency department physicians can usually discriminate clinically between fracture and nonfracture. Decision rules have been developed to reduce the unnecessary use of radiologic studies in patients with acute knee injury. The Ottawa knee rules and the Pittsburgh decision rules are the latest guidelines for the selective use of radiographs in knee trauma. Application of these rules may lead to a more efficient evaluation of knee injuries and a reduction in health costs without an increase in adverse outcomes.
ABSTRACT: Psoriasis is characterized by red, thickened plaques with a silvery scale. The lesions vary in size and degree of inflammation. Psoriasis is categorized as localized or generalized, based on the severity of the disease and its overall impact on the patient's quality of life and well-being. Patient education about the disease and the treatment options is important. Medical treatment for localized psoriasis begins with a combination of topical corticosteroids and coal tar or calcipotriene. For lesions that are difficult to control with initial therapy, anthralin or tazarotene may be tried. The primary goal of therapy is to maintain control of the lesions. Cure is seldom achieved. If control becomes difficult or if psoriasis is generalized, the patient may benefit from phototherapy, systemic therapy and referral to a physician who specializes in the treatment of psoriasis.
Ectopic Pregnancy - Article
ABSTRACT: Ectopic pregnancy occurs at a rate of 19.7 cases per 1,000 pregnancies in North America and is a leading cause of maternal mortality in the first trimester. Greater awareness of risk factors and improved technology (biochemical markers and ultrasonography) allow ectopic pregnancy to be identified before the development of life-threatening events. The evaluation may include a combination of determination of urine and serum human chorionic gonadotropin (hCG) levels, serum progesterone levels, ultrasonography, culdocentesis and laparoscopy. Key to the diagnosis is determination of the presence or absence of an intrauterine gestational sac correlated with quantitative serum beta-subunit hCG (beta-hCG) levels. An ectopic pregnancy should be suspected if transvaginal ultrasonography shows no intrauterine gestational sac when the beta-hCG level is higher than 1,500 mlU per mL (1,500 IU per L). If the beta-hCG level plateaus or fails to double in 48 hours and the ultrasound examination fails to identify an intrauterine gestational sac, uterine curettage may determine the presence or absence of chorionic villi. Although past treatment consisted of an open laparotomy and salpingectomy, current laparoscopic techniques for unruptured ectopic pregnancy emphasize tubal preservation. Other treatment options include the use of methotrexate therapy for small, unruptured ectopic pregnancies in hemodynamically stable patients. Expectant management may have a role when beta-hCG levels are low and declining.
