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.
Health Screening in Older Women - Article
ABSTRACT: Health screening is an important aspect of health promotion and disease prevention in women over 65 years of age. Screening efforts should address conditions that cause significant morbidity and mortality in this age group. In addition to screening for cardiovascular disease, cerebrovascular disease and cancer, primary care physicians should identify risk factors unique to an aging population. These factors include hearing and vision loss, dysmobility or functional impairment, osteoporosis, cognitive and affective disorders, urinary incontinence and domestic violence. Although screening for many conditions cannot be proved to merit an "A" recommendation (indicating conclusive proof of benefit), special attention to these factors can decrease morbidity and improve quality of life in aging women.
ABSTRACT: Early identification of alcohol-related problems is important because these problems are prevalent, pose serious health risks to patients and their families, and are amenable to intervention. Physicians may be able to help patients change their drinking behaviors. The most effective tool for screening is a thorough history of the patient's drinking behavior, designed to identify patterns of alcohol-related difficulties with physical and mental health, family life, legal authorities and employment. Alcohol drinkers can be categorized as at-risk, problem or alcohol dependent, according to a protocol developed by the National Institute on Alcohol Abuse and Alcoholism. The severity of the alcohol problem and the patient's readiness to change should determine the intervention selected by the family physician.
Testicular Cancer - Article
ABSTRACT: Although testicular cancer accounts for only 1 percent of all tumors in males, it is the most common malignancy in males between 15 and 34 years of age. Cryptorchidism is the most significant risk factor for testicular cancer, increasing the risk up to 11-fold. A painless testicular mass is the classic presentation for testicular cancer, although a number of patients present with diffuse pain or swelling. Ultrasonography may be helpful in confirming the presence of a scrotal mass within the testicle. Intratesticular masses are considered malignant until proved otherwise. Radical orchiectomy is the treatment for the primary tumor. Staging of disease is based on tumor histology, serum tumor markers and presence of lymph-node or other metastatic disease. Depending on the stage of disease, further treatment may include observation, radiotherapy, chemotherapy or surgery. Survival rates in patients with testicular cancer have improved dramatically in the past 20 years and now exceed 90 percent overall.
ABSTRACT: Screening programs relying primarily on physical examination techniques for the early detection and treatment of congenital hip abnormalities have not been as consistently successful as expected. Since the 1980s, increased attention has been given to ultrasound imaging of the hip in young infants (less than five months of age) as a possible tool for improving patient outcomes. Although ultrasound examination may not provide advantages over careful repeated physician examination for universal screening, a growing body of evidence indicates that ultrasound surveillance of mild abnormalities can reduce the need for bracing without worsening outcomes. Radiographic documentation of hip normality after the femoral nucleus of ossification has appeared (at three to five month of age) is still appropriate to rule out hip dysplasia.
Treatment of Type 2 Diabetes Mellitus - Article
ABSTRACT: Type 2 diabetes mellitus (formerly called non-insulin-dependent diabetes) causes abnormal carbohydrate, lipid and protein metabolism associated with insulin resistance and impaired insulin secretion. Insulin resistance is a major contributor to progression of the disease and to complications of diabetes. Type 2 diabetes is a common and underdiagnosed condition that poses treatment challenges to family practitioners. The introduction of new oral agents within the past three years has expanded the range of possible combination regimens available for treating type 2 diabetes. Despite the choice of pharmacologic agents, physicians must stress the nonpharmacologic approaches of diet modification, weight control and regular exercise. Pharmacologic approaches must be based on patient characteristics, level of glucose control and cost considerations. Combinations of different oral agents may be useful for controlling hyperglycemia before insulin therapy becomes necessary. A stepped-care approach to drug therapy may provide the most rational, cost-efficient approach to management of this disease. Pharmaco-economic analyses of clinical trials are needed to determine cost-effective treatment strategies for management of type 2 diabetes.
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.
ABSTRACT: The blood sample for phenylketonuria (PKU) screening should be obtained at least 12 hours after the infant's birth. Newborn screening for PKU has largely eliminated mental retardation caused by this disease. If the first phenylalanine test demonstrates positive results, a repeat test should be performed. Treatment to prevent sequelae from this disorder is best carried out in cooperation with an experienced PKU center. Dietary care is expensive, and financial assistance may be necessary for many families. A phenylalanine-restricted diet should be started as soon as possible. Occasionally, cases of PKU are missed by newborn screening. Thus, a repeat PKU test should be performed in an infant who exhibits slow development.
The Evaluation of Common Breast Problems - Article
ABSTRACT: The most common breast problems for which women consult a physician are breast pain, nipple discharge and a palpable mass. Most women with these complaints have benign breast disease. Breast pain alone is rarely a presenting symptom of cancer, and imaging studies should be reserved for use in women who fall within usual screening guidelines. A nipple discharge can be characterized as physiologic or pathologic based on the findings of the history and physical examination. A pathologic discharge is an indication for terminal duct excision. A dominant breast mass requires histologic diagnosis. A breast cyst can be diagnosed and treated by aspiration. The management of a solid mass depends on the degree of clinical suspicion and the patient's age.
Cervical Cancer - Article
ABSTRACT: Cervical cancer is the second most common type of cancer in women worldwide, after breast cancer. A preponderance of evidence supports a causal link between human papillomavirus infection and cervical neoplasia. The presence of high-risk human papillomavirus genital subtypes increases the risk of malignant transformation. Widespread use of the Papanicolaou smear has dramatically reduced the incidence of cervical cancer in developed countries. Accurate and early recognition of abnormal cytologic changes prevents progression of the disease from preinvasive to invasive. Research is under way to determine if efforts to reduce the false-negative rate of the Papanicolaou smear should include rescreening programs and fluid-based technology. Once cervical cancer is diagnosed, clinical staging takes place. Early-stage tumors can be managed with cone biopsy or simple hysterectomy. Higher stage tumors can be treated surgically or with radiotherapy. Advanced metastatic disease may respond to radiation therapy and concurrent chemotherapy. Protein markers for detection of recurrence and vaccines for prevention of cervical cancer are under investigation.
