Obesity

Persons with a systolic blood pressure (BP) of 120 to 139 mm Hg or a diastolic BP of 80 to 89 mm Hg are now considered, according to the latest Joint National Committee (JNC) report on hypertension.

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.

ABSTRACT: Indications for pulmonary function tests (PFTs) have widened substantially, ranging from screening smokers for early lung disease to determining the diagnosis and prognosis of pulmonary conditions. Current indications also include screening for drug-induced lung toxicity and preoperative screening for lung resection surgery. In the workup of respiratory symptoms, such as dyspnea, cough, and wheezing, PFTs can identify obstructive or restrictive patterns that may suggest a diagnosis such as asthma or interstitial lung disease. The ratio of FEV1 to forced vital capacity is very sensitive to the presence of airflow limitation, although bronchoprovocation testing may be needed to diagnose asthma, especially in patients with mild intermittent disease. Measurements of lung volumes and carbon monoxide-diffusing capacity (DLCO) provide crucial information in selected patients. For example, a reduced DLCO may be a sign of more advanced disease, such as emphysema or pulmonary hypertension.Since the first description of the spirometer by John Hutchinson in the late 1800s, pulmonary function tests (PFTs) have expanded to include spirometry; lung volumes; carbon monoxide-diffusing capacity (DLCO) (transfer factor); respiratory muscle performance; and exercise and functional testing, such as the 6-minute walk test (6MWT) and cardiopulmonary exercise testing (CPET).

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.

A 60-year-old man presented to the emergency department (ED) with fever of 1 day’s duration and midabdominal pain. The cramping pain had begun 3 days earlier in a bandlike distribution around the upper abdomen. Ingestion of food exacerbated the discomfort. The patient had a history of intermittent constipation; he denied alcohol or illicit drug use, nausea, vomiting, and weight loss. He did not use any herbal or over-the-counter medications.

An otherwise healthy 38-year-old woman presented to the emergency department with a 1-day history of generalized left-sided weakness. She had no other significant medical history and was taking no medications. The patient was overweight.

Leprosy, or Hansen disease, had recently been diagnosed in a 39-year-old man. He presented to the tropical disease unit of Harare Hospital, Zimbabwe, for follow-up.

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.

The family of a 50-year-oldalcoholic man brings him to youroffice. They are concerned abouthis health and note that they had notseen him for several months beforehe reappeared. The patient complainsof generalized weakness, fatigue, andbleeding gums.

Recently, the National High Blood Pressure Education Program Coordinating Committee updated its 1993 recommendations for primary prevention of hypertension.

ABSTRACT: Many patients with osteoarthritis (OA) try such complementary therapies as special diets, nutritional and herbal supplements, yoga, t'ai chi, magnets, and acupuncture-but only 40% of these patients tell their physicians. Glucosamine and chondroitin sulfate can produce at least symptomatic relief; in addition, glucosamine (1500 mg/d) may increase or stabilize cartilage in osteoarthritic knees. Alert patients to the potential toxicities of many herbal remedies, as well as the risks of harmful drug interactions and possible contaminants and impurities. Yoga postures may have a beneficial effect on knee OA; t'ai chi may reduce joint pain and swelling and increase mobility. Small studies have shown that applied pulsed electromagnetic fields can reduce pain and improve function in patients with chronic knee OA. Acupuncture has also been shown, in small studies, to alleviate the pain of OA. Autologous chondrocyte transplantation was recently approved for treatment of knee OA. The efficacy and safety of various types of gene therapy are currently being evaluated.

For 10 years, a 22-year-old woman had had an erythematous, translucent patch of grouped blisters on her left thigh. A recent increase in the size of the patch prompted the patient to seek treatment. There was no burning or tingling at the site. The patient reported that the erythema occasionally cleared; however, the blisters always remained. She denied fever, weight loss, and other constitutional symptoms.

Asymptomatic, enlarging growths had been present on the bottom of a 56-year-old woman’s feet for 3 years. The nodules initially arose-first on the left foot, then on the right-at the sites of blisters on the insteps after the patient had taken a long hike in uncomfortable boots.

In my view, "very low calorie diet" is a more appropriate term for the type of diet you describe.

The diagnosis of osteoarthritis (OA) is primarily clinical. Key historical clues to idiopathic OA include patient age greater than 45 years, joint pain that increases with activity and is relieved with rest, morning stiffness of 30 minutes duration or less, and involvement of one or more of the following: hips, knees, cervical or lumbar spine, basilar thumb joints, interphalangeal joints of the hands, midfoot joints, and first metatarsophalangeal joints.

ABSTRACT: Topical agents can provide temporary relief from osteoarthritis symptoms with little or no risk. Acetaminophen is first-line oral therapy. Be alert for risk factors for NSAID-induced GI toxicity, such as concurrent use of prescription and OTC agents. Tramadol, narcotic analgesics, muscle relaxants, and antidepressants are options when NSAIDs are ineffective or contraindicated. Intra-articular injections of corticosteroids or hyaluronan are appropriate for patients who have a single joint exacerbation. Total knee and total hip arthroplasty are considered the most effective surgical interventions.

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 42-year-old woman complains of anxiety, unexplained weight loss, and palpitationsthat started about 3 weeks earlier. She denies fever, trauma, and newstress. She has a history of several urinary tract infections for which imagingfailed to reveal any predisposing factors; all were successfully treated withmedication. The remainder of the history is unremarkable.

In the United States, osteoporosis affects 12% to 28% of women over age 65 years. Among women who live to be 85, 50% will sustain an osteoporosis-related fracture. Hip fractures occur in 15% of these women, and vertebral deformities develop in 25%

ABSTRACT: Patients can greatly reduce the risk of traveler's diarrhea by drinking only bottled water and eating only hot foods prepared in sanitary conditions or peelable fruits and vegetables. Antibiotic prophylaxis for traveler's diarrhea is no longer routinely recommended; reserve it for patients who may have to consume food and beverages of questionable safety, those with reduced immunity, and those likely to experience serious consequences of illness. Adequate hydration is the first step in treating traveler's diarrhea. Drug therapy-loperamide or fluoroquinolones in adults and bismuth subsalicylate or azithromycin in children-can ameliorate symptoms and speed recovery. Recommend that patients who are prone to motion sickness take an antiemetic/antivertigo agent before symptoms begin. Acetazolamide can be used both to prevent and to treat altitude sickness. Contraindications to air travel include a resting oxygen saturation of less than 90%, pregnancy of more than 36 weeks' duration, pneumothorax, recent myocardial infarction or chest or abdominal surgery, active infectious diseases, and poorly controlled seizures or sickle cell anemia.

ABSTRACT: A key objective in the follow-up of women with a history of breast cancer is the detection of local and distant disease at a curable stage. Regular clinical examination and yearly mammography are the standard of care. No consistent evidence supports annual chest radiography, bone scans, or tests of serum tumor markers. Order laboratory or diagnostic tests only if indicated by clinical findings. Advise women to report new symptoms promptly rather than waiting for the next scheduled examination. Some evidence supports the use of venlafaxine for tamoxifen-associated hot flashes. Despite the increased incidence of endometrial carcinoma in women taking tamoxifen, routine endometrial biopsies are not recommended. Most experts advise that women with a history of breast cancer who wish to have a child wait 2 to 3 years before becoming pregnant.

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.

During a routine office visit, a 64-year-old woman who has had type 2 diabetesfor more than 10 years complains of increased pedal edema. The edema is minimalon awakening and worsens throughout the day.

For 1 month, a 25-year-old woman had experienced discomfort in and around the left eye and diplopia. She was in good health; she reported no weight loss, excessive nervousness, heat intolerance, decreased strength, changes in the texture of hair or skin, or altered bowel habits. There was no personal or family history of goiter or other thyroid disease.

Although acute low back pain usuallyresolves within 6 weeks-with or withouttreatment-the pain may signal asignificant neurologic or life-threateningdisease that warrants immediateintervention.

More than1.8 millioncardiaccatheterizationsandat least 600,000 percutaneoustransluminal coronaryangioplasty (PTCA)procedures are performedin the United States annually.1 The use of these diagnosticand interventionalmodalities continues togrow even as financial constraintsincrease. Yet formany patients with coronaryartery disease (CAD),medical therapy may be anappropriate option.

A 22-year-old Filipino man with fever, lethargy, weakness, and malaise of 5 days' duration was brought to the emergency department by his family. Two days earlier, oral penicillin had been prescribed for streptococcal pharyngitis. The patient was unable to walk because of profound weakness. Circular and linear ecchymotic lesions were noted on his back.

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

ABSTRACT: Exercise can be an effective way to stabilize or slow the degenerative process of osteoarthritis-provided convenient, safe, and enjoyable activities are selected and achievable goals are set. Implement an osteoarthritis exercise plan in phases, and progress gradually from one phase to the next; this will help both you and your patient anticipate difficulties and gauge progress. The first phase-the initial evaluation-includes gathering baseline data, targeting an area of the body to focus on first, and identifying potential contraindications to activities. Subsequent phases include range of motion exercises (stretching), isometric and isotonic strengthening exercises, and recreational or functional activities. Encourage patients to continue stretching exercises throughout the program.
