A 34-year-old white woman presentswith a 4-month history of diarrhea,with bulky, foul-smelling stools; flatulence;diffuse abdominal discomfort;and episodic nausea and vomiting. Shehas lost 13.5 kg (30 lb) during this period.The patient has had no fever, andher medical, family, and travel historyare unremarkable.

For several months, a 70-year-old woman had had dysphagia,mild dyspnea on exertion, and the Raynaud phenomenon.Her skin was waxy and edematous; 2- to 10-mm pinkishspots had appeared on her fingers, palms, and oral mucousmembrane over the past 2 weeks. These disappearedcompletely with pressure. Subcutaneous calcific depositswere present on the extensor surfaces of the forearms.

A 65-year-old woman, who was confined to a wheelchairbecause of severe rheumatoid arthritis, was concernedabout nodules that had erupted on her fingers and handsduring the previous 3 weeks (A). Her medical historyincluded colon cancer, chronic renal insufficiency, anemia,and hypertension. The nonpruritic nodules were painfulwhen they began to form under the skin; however, oncethey erupted, the pain disappeared.

Ten weeks before presentation, this55-year-old woman noticed decreasedsensation in her feet and a bluish discolorationof her toes. These symptomsprogressed rapidly, and pain andcoldness in both feet increased in intensity.Her feet subsequently becamegangrenous. Her seropositive arthritishad been diagnosed about 6 yearsearlier. The disease had been wellcontrolled until about 10 weeks beforethis photograph was taken.

Bilateral swelling and pain in the distal interphalangeal (DIP) joints for severalmonths brought this 65-year-old woman to her physician. She complained alsoof stiffness in the region of the DIP joints when she arose in the morning andafter short periods (less than 15 minutes) of inactivity. A history such as this,in conjunction with the appearance of the patient’s hand, is typical of Heberdennodes, which are a manifestation of osteoarthritis (OA).

Extreme synovial inflammation resulted in the articular degradation seen in the hands of this 40-year-old woman who has Still disease, or juvenile rheumatoid arthritis (JRA).

ABSTRACT: The auscultatory features of heart murmurs-intensity, frequency, quality, configuration, timing, duration, and radiation-can help identify a variety of cardiac disorders. Systolic ejection murmurs have a crescendo-decrescendo configuration. These include innocent murmurs and those associated with aortic stenosis and hypertrophic cardiomyopathy. Systolic murmurs associated with retrograde flow from a high-pressure chamber to a low-pressure chamber usually have a holosystolic configuration. Examples of holosystolic murmurs include mitral regurgitation, tricuspid regurgitation, and the murmur associated with a ventricular septal defect. Diastolic murmurs include regurgitant murmurs, such as the decrescendo murmur of aortic regurgitation, and filling murmurs, such as the presystolic rumble of mitral stenosis, which is preceded by an opening snap. The murmur associated with patent ductus arteriosus is continuous.

Numerous factors put elderly patients at risk for adverse drug events. On average, they take at least 6 medications a day, which increases the likelihood of drug-drug interactions. In addition, many drugs that are safe and effective in younger patients are inappropriate for older persons because of age-related changes and comorbid conditions that affect absorption, distribution, metabolism, and elimination. First-pass metabolism decreases with age, which may increase systemic absorption of some oral nitrates, ß-blockers, estrogens, and calcium channel blockers. The age-related rise in body fat increases the volume of distribution of lipid-soluble compounds, such as diazepam, and prolongs clearance. About two thirds of elderly persons have impaired kidney function; in these patients, the dosage of renally excreted drugs-such as digoxin-needs to be reduced. Other strategies for avoiding adverse drug events are detailed here.

ABSTRACT: The basic screening studies for rheumatic diseases are a complete blood cell count, a determination of the erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) level, a rheumatoid factor assay, an antinuclear antibody (ANA) test, a measurement of serum uric acid level, and a urinalysis. Test results must be interpreted within a clinical context; for example, a positive ANA assay suggests the possibility of a rheumatic disorder, but it is not specific for any diagnosis. Tests that reveal the nature and extent of target-organ involvement, such as renal function studies in patients with systemic lupus erythematosus, can help guide the selection of therapy. Laboratory results also reflect disease activity; the ESR and CRP level are useful gauges of the activity of most inflammatory rheumatic disorders. Finally, laboratory monitoring can help you minimize the significant toxicity associated with many of the drugs used to manage rheumatic diseases.

A52-year-old white man presented with a pruritic eruption on the neck of 3 months’ duration. The rash had not responded to a potent topical corticosteroid prescribed by another practitioner for the presumed diagnosis of eczema. The patient reported no current health problems. His history included a pubic louse infestation and several episodes of uncomplicated urethral gonorrhea. He readily admitted to having unprotected sexual intercourse with prostitutes.

The parents of a 3-year-old girl sought evaluation of their daughter’s hair loss.During the past several months, a large patch of alopecia with scaling had developed.The differential diagnosis included seborrhea, trichotillomania, andtinea capitis.

Numerous factors contribute to the medication errors that kill up to 98,000 patients each year. Unnecessarily high dosages can result in increased side effects with only a small therapeutic benefit, especially in elderly patients. Lack of patient information-such as a history of allergies or adverse drug reactions-is another cause of error and injury. Communication failures include the use of ambiguous abbreviations, misinterpretation of verbal orders, and lack of timely response to a patient's medication-related symptoms. Dosing errors are common in children because of variability in dosage expressions in drug references. Remedies for prescribing errors are described in detail here.

Treatment of fibromyalgia syndrome (FMS) is a challenge. However, most patients benefit from appropriate management. Essential to treatment are a physician's positive and empathetic attitude, continuous psychological support, patient education, patience, and a willingness to guide patients to do their part in management. Other important aspects involve addressing aggravating factors (eg, poor sleep, physical deconditioning, emotional distress) and employing various nonpharmacologic modalities (eg, regular physical exercise) and pharmacologic therapies. Drug treatment includes use of tricyclic medications alone or in combination with a selective serotonin reuptake inhibitor, and other centrally acting medications. Tender point injection is useful. It is important to individualize treatment. Management of FMS is both a science and an art.

A 13-year-old girl of African American descent is brought to the pediatrician’s office becauseof a lesion on her neck. The girl’s mother had telephoned the office before the visit, statingthat the lesion resembled a blister at first, but now looked like a burn.

Vague abdominal pain, malaise, anorexia,and the loss of 10 lb in 2months prompted a 65-year-old manto seek medical evaluation. A yearearlier he had undergone surgery forstage III carcinoma of the sigmoidcolon. Because metastases to thelymph nodes were found in the resectedcolon, the patient was given postoperativechemotherapy. Histologicexamination revealed poorly differentiatedadenocarcinoma.

A 40-year-old man was concerned about an enlarging painlessmass on the right side of his neck that had been presentfor 6 months (A). The patient reported no other healthproblems; his medical history was unremarkable, and hewas taking no medications.There was no family or personal history of thyroiddisease or of exposure to radiation. Thyroid function testresults were within normal limits. A chest film revealed nopathology.

Is hypertension a frequent manifestation of thyroid disease?Which clinical clues suggest hypertension in persons with thyroiddysfunction?

An 86-year-old woman had noted intermittent, transient “shading” and “hazing” of the vision in her right eye. Her best corrected vision in that eye was 20/20. She had pseudophakia from past cataract surgery.

An 87-year-old woman complained ofseeing a red tinge on the wallpaper inher house through her right eye. Thepatient had mild memory loss andmoderate hypertension, for whichshe took atenolol. She had quit smokingcigarettes many years earlier.

During an annual eye examination, a 65-year-old womanwith a 5-year history of type 2 insulin-dependent diabetescomplained that her vision had slightly worsened in botheyes. Her best corrected visual acuity was 20/30 in botheyes.
