Depression

ABSTRACT: The results of diagnostic tests do not correlate well with the presence and severity of pain. To avoid missing a serious underlying condition, look for "red flags," such as unexplained weight loss or acute bladder or bowel function changes in a patient with low back pain. Nonopioid medications can be more effective than opioids for certain types of pain (for example, antidepressants or anticonvulsants for neuropathic pain). When NSAIDs are indicated, cyclooxygenase-2 inhibitors are better choices for patients who are at risk for GI problems or who are receiving anticoagulants. However, if nonspecific NSAIDs are not contraindicated, consider using these far less expensive agents. The tricyclic antidepressants are more effective as analgesics than selective serotonin reuptake inhibitors. When opioids are indicated, start with less potent agents (tramadol, codeine, oxycodone, hydrocodone) and then progress to stronger ones (hydromorphone, fentanyl, methadone, morphine) if needed.

ain management is a commonand challenging aspect of caringfor elderly patients. The principlesthat guide therapeutic pain managementin these persons are differentfrom those used in the treatmentof younger persons.

Uncontrolled hypertension is a major health problem among African Americans. Obesity, high sodium and low potassium intake, and inadequate physical activity have been identified as barriers to cardiovascular health in many African Americans. Thus, it is important to educate and counsel patients about lifestyle modifications, such as a low-sodium, DASH (Dietary Approaches to Stop Hypertension)-type diet; regular aerobic exercise; moderation of alcohol consumption; and smoking cessation. All classes of antihypertensive agents lower blood pressure in African Americans, although some may be less effective than others when used as monotherapy. Most patients require combination therapy. Both patient barriers (such as lack of access to health care and perceptions about health and the need for therapy) and physician barriers (such as poor communication styles) contribute to the low rates of hypertension control in African Americans. Patient-centered communication strategies can help overcome these barriers and can improve compliance and outcomes. Such strategies include the use of open-ended questions, active listening, patient education and counseling, and encouragement of patient participation in decision making.

ABSTRACT: Once you have excluded a cardiac origin of chest pain, focus the evaluation on esophageal, psychiatric, musculoskeletal, and pulmonary causes. Gastroesophageal reflux disease (GERD) and esophageal motility disorders are the most common causes of unexplained chest pain (UCP). If you suspect an esophageal disorder, empiric antisecretory therapy is the most cost-effective initial approach. If the patient remains symptomatic, order a 24-hour esophageal pH study with symptom analysis while the patient receives maximal acid suppression. Once GERD is excluded, the patient may be treated for visceral hyperalgesia with low-dose tricyclic antidepressants or standard doses of selective serotonin reuptake inhibitors. Panic disorder-the most common psychiatric disorder in patients with UCP-is often associated with atypical symptoms, such as palpitations and paresthesias, and other psychiatric disorders. If you suspect panic disorder, one approach is to give the patient a short-term, nonrefillable prescription for a benzodiazepine and refer him or her for psychiatric evaluation.

An examination the most recent data on the pharmacodynamics, efficacy, and safety of 5 commonly used herbs: echinacea, St John's wort, ginkgo biloba, saw palmetto, and black cohosh.

ABSTRACT: Fibromyalgia syndrome (FMS) is a common condition that causes chronic pain and disability. It should be diagnosed by its own clinical characteristics of widespread musculoskeletal pain and multiple tender points. American College of Rheumatology criteria guidelines are most helpful in diagnosing FMS. The major symptoms are pain, stiffness, fatigue, poor sleep, and those of other associated conditions, for example, irritable bowel syndrome, headaches, restless legs syndrome, chronic fatigue syndrome, and depression. The pathophysiology of FMS is thought to involve central sensitization and neuroendocrine aberrations, triggered or aggravated by genetic predisposition; trauma; psychosocial distress; sleep deprivation; and peripheral nociception.

n the United States, the number of cases and geographic range of West Nile virus infection have increased since 1999, when the virus first surfaced in the Western Hemisphere. This year, the virus is expected to spread to all states except Alaska and Hawaii.

ABSTRACT: When a patient presents with low back pain, ask about the location and quality of the pain, what makes the pain increase or decrease, associated symptoms, and risk factors. Clues to systemic causes of low back pain include fever; arthritis; iritis; signs and/or symptoms of GI disease, pelvic disease, or renal disease; tachycardia; and integumentary abnormalities. Perform a neurovascular evaluation as well as a detailed musculoskeletal examination. Imaging studies are not necessary for most patients initially. Acute therapy consists of the application of cold and heat and analgesics such as acetaminophen or an NSAID. Early exercise-not bed rest-is the cornerstone of treatment. Follow-up is mandatory: in 3 to 7 days for patients with severe pain, inconsistent findings, mild neurologic abnormalities, or a history of progres- sive symptoms; and in 10 to 14 days for patients with no neurologic compromise.

The Geriatric Depression Scale is the most widelyvalidated screening tool. The questionnaire has beenreduced to a single question that is as sensitive and as specificas the 15-item shortened form of the original 30-itemscale. The question is: "How often do you feel sad or depressed?'This is certainly something that is easy to ask inthe course of a general physical examination or routine officevisit.

ABSTRACT: Infant colic is a diagnosis of exclusion; its true cause is not known. To rule out alternative diagnoses, obtain a detailed history, look for clues to an underlying organic disease or genetic syndrome, and perform regular head-to-toe physical examinations. The interventions most commonly used to treat colic include modification of parental behavior (such as increased carrying of the infant or decreased infant stimulation), milk- and/or soy-free formulas, modifications in the diet of a breast-feeding mother, soothing measures (such as car rides, rocking, or use of a pacifier), anticholinergic agents, sedatives, and alternative medicine approaches (such as sucrose solution, herbal teas, or infant massage). The medications used to treat colic-such as antispasmodics and anticholinergics-can have serious adverse effects; discuss the pros and cons of drug therapy with parents before prescribing these agents. Remind parents that colic resolves by age 3 to 4 months, regardless of the intervention used.

Excessive belching, abdominal bloating, and flatulence caused an 89-year-old woman to seek medical attention. She reported that these previously mild and intermittent symptoms of 20 years’ duration had worsened during the last 2 years.

Persons with severe mental illnesses (SMI), such as schizophrenia, are at increased risk for comorbid conditions- including type 2 diabetes-independent of therapy. SMI sufferers especially at risk for type 2 diabetes are women, African Americans, and persons older than 45 years. Among the possible causes of increased susceptibility to type 2 diabetes are such schizophrenia-associated conditions as impaired glucose tolerance, overweight, obesity, inadequate nutrition, lack of exercise, and inadequate self-care. Other obstacles to good health care among patients with schizophrenia include impaired communication ability, denial of illness, social withdrawal, and undertreatment because of comorbid conditions. Different antipsychotic medications may also contribute to preexisting insulin resistance or glucose intolerance. Clinicians can optimize care by understanding the most significant barriers for each patient and incorporating this knowledge into an active treatment plan.

Back pain is second only to upper respiratory tract infection as the most frequently reported illness in the United States; up to 20% of Americans experience back pain each year.

Cardiac stress imaging has become increasingly sophisticated; nevertheless, standard exercise electrocardiography can provide valuable clinical information, such as time to onset of angina or ST-segment depression, maximal heart rate and blood pressure response, and total exercise duration. Pharmacologic stress agents may be substituted for patients who cannot exercise on a treadmill; however, these agents must be used in conjunction with echocardiography or nuclear scintigraphy to obtain adequate diagnostic information.

A 41-year-old woman has had a 2-week bout of nausea, vomiting, and diarrhea.Her history includes chronic hepatitis C and alcohol abuse. She also has orthostatichypotension. A baseline ECG is obtained.

The most common blood-borne infection in the United States, hepatitis C is also one of the leading causes of chronic liver disease in this country. About 35,000 new hepatitis C virus (HCV) infections are diagnosed each year; by 2015, the number of persons with documented HCV infection is expected to have increased 4-fold from what it was in 1990.

Smoking-related diseases have reached epidemic levelsamong women in the United States. Since 1980, neoplastic,cardiovascular, respiratory, and pediatric diseases attributableto smoking-as well as cigarette burns-havebeen responsible for the premature deaths of 3 millionAmerican women and girls. Lung cancer is now the leadingcause of cancer-related deaths among US women; itsurpassed breast cancer in 1987.1

ABSTRACT: Age-related anatomic and physiologic alterations in the thyroid gland have a variety of clinically important effects. Hypothyroidism, which is common in older persons, raises cholesterol and triglyceride levels; hyperthyroidism may be masked by the severity of the cardiac problems it causes. In younger persons, depression may accompany hypothyroidism but not hyperthyroidism; however, in the elderly, it may be a feature of either condition. Papillary carcinoma-the most common type of thyroid cancer-is more aggressive in older persons. All these factors necessitate a cautious and deliberate approach to the management of thyroid disorders in elderly patients.

ABSTRACT: For patients who present with ventricular fibrillation (VF) or pulseless ventricular tachycardia that is refractory to repeated countershocks, the drug of choice is amiodarone; the recommended dose for those who are receiving cardiopulmonary resuscitation is 300 mg given as an IV bolus. Vasopressin, 40 U IV, is an acceptable alternative to epinephrine in adults with VF that is resistant to electrical defibrillation. Standard heparin or low molecular weight heparin is indicated in patients who require reperfusion therapy and in those who have unstable angina or non-Q wave myocardial infarction (MI). The initial therapy for patients with acute myocardial ischemia usually includes morphine, oxygen, nitroglycerin, and aspirin, plus a ß-adrenergic blocking agent. Glycoprotein IIb/IIIa receptor inhibitors are currently recommended for patients who have non-Q wave MI or high-risk unstable angina.

ABSTRACT: A thorough history and physical examination can establish the diagnosis of tension headache; further evaluation is generally unnecessary. In contrast, the workup of cervicogenic headache includes standard radiographs, 3-dimensional CT, MRI, and possibly electromyography; nerve blocks may also be used to confirm the diagnosis. Episodic tension headache can be treated effectively by trigger avoidance, behavioral modalities, and structured use of analgesics. Reserve opioids for patients with intractable headaches. Chronic tension headache is treated primarily by prophylactic measures, such as antidepressants and anticonvulsants, and behavioral and physical therapy. Treatment options for cervicogenic headache include analgesics; invasive procedures, such as trigger point injections, greater or lesser occipital nerve blocks, facet joint blocks, segmental nerve root blocks, and diskography; spinal manipulation; and behavioral approaches.

As the world of sport has embraced the participation of women and girls, the incidence of health problems that pertain specifically to premenopausal female athletes has increased significantly. One of these is the female athlete triad, which consists of 3 interrelated medical conditions associated with athletic training

A 72-year-old man sought medical evaluationafter he awoke and was unableto open his right eyelid (A). He deniedpain, recent trauma, and diplopia. Thispatient’s history included well-controlledhypertension and hypercholesterolemia,for which he was taking atorvastatin.He did not have diabetes.

Persistent pain is common in older adults but tends to be underrecognized and undertreated. Up to 50% of community-dwelling older persons have significant painand up to 80% of nursing home residents have substantial pain that is undertreated.

A 65-year-old woman with a long history of hypertension treated with metoprolol and felodipine complained of dizziness, headache, nausea, and vomiting of acute onset. Her blood pressure was 220/110 mm Hg. She was drowsy and unable to stand or walk.

A 72-year-old man slipped and fell backward in the bathroom, hitting hishead on the toilet seat; he suffered only minimal discomfort. The followingday, he presented with mild back pain and extensive bruising.
