Vulvar Cancer - Article

ABSTRACT: Vulvar cancer was reported in 3,200 women in 1998, resulting in 800 deaths. Recent evidence suggests that vulvar cancer comprises two separate diseases. The first type may develop from vulvar intraepithelial neoplasia caused by human papillomavirus infection and is increasing in prevalence among young women. The second type, which more often afflicts older women, may develop from vulvar non-neoplastic epithelial disorders as a result of chronic inflammation (the itch-scratch-lichen sclerosus hypothesis). Although vulvar cancer is relatively uncommon, early detection remains crucial given its significant impact on sexuality. Diagnosis is based on histology; therefore, any suspicious lesions of the vulva must be biopsied. Excisional or punch biopsy can be performed in the physician's office. Clinicians must closely monitor suspicious lesions because delayed biopsy and diagnosis are common. Once diagnosed, vulvar cancer is staged using the TNM classification system. Treatment is surgical resection, with the goal being complete removal of the tumor. There has been a recent trend toward more conservative surgery to decrease psychosexual complications.


Preoperative Cardiac Risk Assessment - Article

ABSTRACT: Heart disease is the leading cause of mortality in the United States. An important subset of heart disease is perioperative myocardial infarction, which affects approximately 50,000 persons each year. The American College of Cardiology (ACC) and American Heart Association (AHA) have coauthored a guideline on preoperative cardiac risk assessment, as has the American College of Physicians (ACP). The ACC/AHA guideline uses major, intermediate, and minor clinical predictors to stratify patients into different cardiac risk categories. Patients with poor functional status or those undergoing high-risk surgery require further risk stratification via cardiac stress testing. The ACP guideline also starts by screening patients for clinical variables that predict perioperative cardiac complications. However, the ACP did not feel there was enough evidence to support poor functional status as a significant predictor of increased risk. High-risk patients would sometimes merit preoperative cardiac catheterization by the ACC/AHA guideline, while the ACP version would reserve catheterization only for those who were candidates for cardiac revascularization independent of their noncardiac surgery. A recent development in prophylaxis of surgery-related cardiac complications is the use of beta blockers perioperatively for patients with cardiac risk factors.


Lipoma Excision - Article

ABSTRACT: Lipomas are adipose tumors that are often located in the subcutaneous tissues of the head, neck, shoulders, and back. Lipomas have been identified in all age groups but usually first appear between 40 and 60 years of age. These slow-growing, nearly always benign, tumors usually present as nonpainful, round, mobile masses with a characteristic soft, doughy feel. Rarely, lipomas can be associated with syndromes such as hereditary multiple lipomatosis, adiposis dolorosa, Gardner's syndrome, and Madelung's disease. There are also variants such as angiolipomas, neomorphic lipomas, spindle cell lipomas, and adenolipomas. Most lipomas are best left alone, but rapidly growing or painful lipomas can be treated with a variety of procedures ranging from steroid injections to excision of the tumor. Lipomas must be distinguished from liposarcoma, which can have a similar appearance.


Management of Hip Fracture: The Family Physician's Role - Article

ABSTRACT: The incidence of hip fracture is expected to increase as the population ages. One in five persons dies in the first year after sustaining a hip fracture, and those who survive past one year may have significant functional limitation. Although surgery is the main treatment for hip fracture, family physicians play a key role as patients' medical consultants. Surgical repair is recommended for stable patients within 24 to 48 hours of hospitalization. Antibiotic prophylaxis is indicated to prevent infection after surgery. Thromboprophylaxis has become the standard of care for management of hip fracture. Effective agents include unfractionated heparin, low-molecular-weight heparin, fondaparinux, and warfarin. Optimal pain control, usually with narcotic analgesics, is essential to ensure patient comfort and to facilitate rehabilitation. Rehabilitation after hip fracture surgery ideally should start on the first postoperative day with progression to ambulation as tolerated. Indwelling urinary catheters should be removed within 24 hours of surgery. Prevention, early recognition, and treatment of contributing factors for delirium also are crucial. Interventions to help prevent future falls, exercise and balance training in ambulatory patients, and the treatment of osteoporosis are important strategies for the secondary prevention of hip fracture.


Caring for Patients After Bariatric Surgery - Article

ABSTRACT: Bariatric surgery leads to sustainable long-term weight loss and may be curative for such obesity-related comorbidities as diabetes and obstructive sleep apnea in severely obese patients. The Roux-en-Y gastric bypass has become the most common procedure for patients undergoing bariatric surgery. The procedure carries a mortality risk of up to 1 percent and a serious complication risk of up to 10 percent. Indications include body mass index of 40 kg per m2 or greater, or 35 kg per m2 or greater with serious obesity-related comorbidities (e.g., diabetes, obstructive sleep apnea, coronary artery disease, debilitating arthritis). Pulmonary emboli, anastomotic leaks, and respiratory failure account for 80 percent of all deaths 30 days after bariatric surgery; therefore, appropriate prophylaxis for venous thrombo-embolism (including, in most cases, low-molecular-weight heparin) and awareness of the symptoms of common complications are important. Some of the common short-term complications of bariatric surgery are wound infection, stomal stenosis, marginal ulceration, and constipation. Symptomatic cholelithiasis, dumping syndrome, persistent vomiting, and nutritional deficiencies may present as long-term complications.


Preparation of the Cardiac Patient for Noncardiac Surgery - Article

ABSTRACT: Approximately 20 to 40 percent of patients at high risk of cardiac-related morbidity develop myocardial ischemia perioperatively. The preferred approach to diagnostic evaluation depends on the interactions of patient-specific risk factors, surgery-specific risk factors, and exercise capacity. Stress testing should be reserved for patients at moderate to high risk undergoing moderate- or high-risk surgery and those who have poor exercise capacity. Further cardiovascular studies should be limited to patients who are at high risk, have poor exercise tolerance, or have known poor ventricular function. Medical therapy using beta blockers, statins, and alpha agonists may be effective in high-risk patients. The evidence appears to be the strongest for beta blockers, especially in high-risk patients with proven ischemia on stress testing who are undergoing vascular surgery. Many questions remain unanswered, including the optimal role of statins and alpha agonists, whether or not these therapies are as effective in patients with subclinical coronary artery disease or left ventricular dysfunction, and the optimal timing and dosing regimens of these medications.


Preoperative Evaluation - Article

ABSTRACT: A history and physical examination, focusing on risk factors for cardiac, pulmonary and infectious complications, and a determination of a patient's functional capacity, are essential to any preoperative evaluation. In addition, the type of surgery influences the overall perioperative risk and the need for further cardiac evaluation. Routine laboratory studies are rarely helpful except to monitor known disease states. Patients with good functional capacity do not require preoperative cardiac stress testing in most surgical cases. Unstable angina, myocardial infarction within six weeks and aortic or peripheral vascular surgery place a patient into a high-risk category for perioperative cardiac complications. Patients with respiratory disease may benefit from perioperative use of bronchodilators or steroids. Patients at increased risk of pulmonary complications should receive instruction in deep-breathing exercises or incentive spirometry. Assessment of nutritional status should be performed. An albumin level of less than 3.2 mg per dL (32 g per L) suggests an increased risk of complications. Patients deemed at risk because of compromised nutritional status may benefit from pre- and postoperative nutritional supplementation.
