ABSTRACT: Recreational scuba diving has become a popular sport in the United States, with almost 9 million certified divers. When severe diving injury occurs, the nervous system is frequently involved. In dive-related barotrauma, compressed or expanding gas within the ears, sinuses and lungs causes various forms of neurologic injury. Otic barotrauma often induces pain, vertigo and hearing loss. In pulmonary barotrauma of ascent, lung damage can precipitate arterial gas embolism, causing blockage of cerebral blood vessels and alterations of consciousness, seizures and focal neurologic deficits. In patients with decompression sickness, the vestibular system, spinal cord and brain are affected by the formation of nitrogen bubbles. Common signs and symptoms include vertigo, thoracic myelopathy with leg weakness, confusion, headache and hemiparesis. Other diving-related neurologic complications include headache and oxygen toxicity.
ABSTRACT: In the past decade, cases of babesiosis in humans have been reported with increasing frequency, especially in the northeastern United States. Babesia microti (in the United States) and bovine strains (in Europe) cause most infections in humans. Most cases are tick-borne, although cases of transfusion-associated and transplacental/perinatal transmission have also been reported. Factors associated with more severe disease include advanced age, previous splenectomy and immunodeficient states. Symptoms include high fever, chills, diaphoresis, weakness, anorexia and headache. Later in the course of the illness, the patient may develop jaundice. Congestive heart failure, renal failure and acute respiratory distress syndrome are the most common complications. Therapy using the combination of quinine sulfate and clindamycin was the most commonly used treatment; however, atovaquone suspension plus azithromycin was recently reported an equally effective and less toxic therapy. Exchange transfusion, together with antibabesial chemotherapy, may be necessary in critically ill patients.
ABSTRACT: Cirrhosis is a diffuse process characterized by fibrosis and the conversion of normal liver architecture into structurally abnormal nodules. The modified Child-Pugh score, which ranks the severity of cirrhosis based on signs and liver function test results, has been shown to predict survival. Strategies have been established to prevent complications in patients with cirrhosis. Esophageal varices can be identified by endoscopy; if large varices are present, prophylactic nonselective beta blocker therapy should be administered. Alpha-fetoprotein testing and ultrasonography can be effective in screening for hepatocellular carcinoma. Vaccines should be administered to prevent secondary infections. The use of nonsteroidal anti-inflammatory drugs should be avoided, and patients should maintain a balanced diet containing 1 to 1.5 g of protein per kg per day. An extensive assessment should be performed before patients with cirrhosis undergo elective surgery. Before advanced liver decompensation occurs, patients should be referred for liver transplantation evaluation. If advanced cirrhosis is present and transplantation is not feasible, survival is between one and two years.
ABSTRACT: Cardiovascular disease is the leading cause of death in women, as well as an important cause of disability, although many women and their physicians underestimate the risk. Exercise, hypertension treatment, smoking cessation and aspirin therapy are effective measures for the primary prevention of coronary artery disease in women. The roles of lipid-lowering agents and hormone replacement therapy in primary prevention are not well established. In secondary prevention, hormone replacement therapy has not been effective in lowering the risk of recurrent myocardial infarction, but several lipid-lowering agents have been shown to reduce this risk and to lower mortality rates in women with known coronary artery disease. Other secondary prevention measures, including aspirin, beta blockers, angiotensin-converting enzyme inhibitors, revascularization and rehabilitation, have proven benefits in women but are underused, especially in minority women. Family physicians should emphasize the use of proven treatments, with particular attention given to underserved populations.
ABSTRACT: Family physicians must proactively address the sexual health of their patients. Effective sexual health care should address wellness considerations in addition to infections, contraception, and sexual dysfunction. However, physicians consistently underestimate the prevalence of sexual concerns in their patients. By allocating time to discuss sexual health during office visits, high-risk sexual behaviors that can cause sexually transmitted diseases, unintended pregnancies, and unhealthy sexual decisions may be reduced. Developing a routine way to elicit the patient's sexual history that avoids judgmental attitudes and asks the patient for permission to discuss sexual function will make it easier to gather the necessary information. Successful integration of sexual health care into family practice can decrease morbidity and mortality, and enhance well-being and longevity in the patient.
Prevention of Malaria in Travelers - Article
ABSTRACT: Malaria is a major international public health problem, responsible for considerable morbidity and mortality around the world each year. As travel to tropical locations increases, U.S. physicians are being asked more frequently to provide recommendations for malaria prevention. An organized approach to reducing the risk of acquiring this disease is necessary. Physicians must review the itineraries of their patients in detail, paying particularly close attention to travel within malaria-endemic areas and drug-resistant zones. Appropriate chemoprophylaxis must be chosen to reduce the risk of acquiring malaria. It also is important to provide advice on the use of protective measures that reduce the risk of mosquito bites. Finally, travelers should be instructed to seek medical attention immediately if symptoms of the disease develop during or after the trip.
ABSTRACT: Stroke is a leading cause of morbidity and mortality in North America. Primary prevention of stroke includes lifestyle modifications and measures to control blood pressure, cholesterol levels, diabetes mellitus, and atrial fibrillation. Lowering blood pressure in patients with hypertension prevents both hemorrhagic and ischemic stroke (relative risk reduction, 35 to 45 percent). Observational studies suggest that higher cholesterol levels are associated with an increased risk of ischemic stroke, and treatment with statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) may reduce the risk of fatal and nonfatal stroke by 25 percent. Although high-quality evidence linking tighter glucose control with stroke reduction is lacking, good glucose control and aggressive treatment of hypertension and hyperlipidemia in patients with diabetes mellitus are recommended. The risk of stroke in patients with atrial fibrillation and the role of anticoagulation depend on factors such as age and the presence of comorbid conditions. Controversy exists about the roles of angiotensin-converting enzyme inhibitors and aspirin in the primary prevention of stroke.
ABSTRACT: Men who have sex with men often do not reveal their sexual practices or sexual orientation to their physician. Lack of disclosure from the patient, discomfort or inadequate training of the physician, perceived or real hostility from medical staff, and insufficient screening guidelines limit preventive care. Because of greater societal stresses, lack of emotional support, and practice of unsafe sex, men who have sex with men are at increased risk for sexually transmitted diseases (including human immunodeficiency virus infection), anal cancer, psychologic and behavioral disorders, drug abuse, and eating disorders. Recent trends indicate an increasing rate of sexual risk-taking among these men, particularly if they are young. Periodic screening should include a yearly health risk and physical assessment as well as a thorough sexual and psychologic history. The physician should ask questions about sexual orientation in a nonjudgmental manner; furthermore, confidentiality should be addressed and maintained. Office practices and staff should be similarly nonjudgmental, with confidentiality maintained. Targeted screening for sexually transmitted diseases, depression, substance abuse, and other disorders should be performed routinely. Screening guidelines, while inconsistent and subject to change, offer some useful suggestions for the care of men who have sex with men.
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.
The Patient with Daily Headaches - Article
ABSTRACT: The term 'chronic daily headache' (CDH) describes a variety of headache types, of which chronic migraine is the most common. Daily headaches often are disabling and may be challenging to diagnose and treat. Medication overuse, or drug rebound headache, is the most treatable cause of refractory daily headache. A pathologic underlying cause should be considered in patients with recent-onset daily headache, a change from a previous headache pattern, or associated neurologic or systemic symptoms. Treatment of CDH focuses on reduction of headache triggers and use of preventive medication, most commonly anti-depressants, antiepileptic drugs, and beta blockers. Medication overuse must be treated with discontinuation of symptomatic medicines, a transitional therapy, and long-term prophylaxis. Anxiety and depression are common in patients with CDH and should be identified and treated. Although the condition is challenging, appropriate treatment of patients with CDH can bring about significant improvement in the patient's quality-of-life.
