ABSTRACT: The diagnosis of urinary tract infection (UTI) can be difficult in elderly patients, who may present with vague complaints or atypical symptoms. Office-based urine testing is less sensitive and specific in these patients because they are less likely to have pyuria and more likely to have contaminated specimens than younger adults. Antibiotics used to treat uncomplicated UTIs in the elderly include trimethoprim-sulfamethoxazole (TMP-SMX), fluoroquinolones, fosfomycin, nitrofurantoin, cephalosporins, carbenicillin, and trimethoprim. When you select an agent, consider the side-effect profile, cost, bacterial resistance, likelihood of compliance, and the patient's renal function. The optimal duration of treatment of uncomplicated UTIs in elderly women is still a matter of debate. Options for prophylaxis in patients who have recurrent uncomplicated UTIs include estrogen replacement therapy (vaginal or oral) and nitrofurantoin.
A 53-year-old man with a 20-year history of type 2 diabetes mellitus (for which he required insulin) sought evaluation of a hot, swollen right foot that seemed to have become “flat.” He had no pain, fever, or chills. The patient’s metatarsal bones were readily movable, consistent with Charcot joint. Further workup ruled out osteomyelitis. Plain films demonstrated extensive deformity of the tarsal and metatarsal bones with Lisfranc fracture/dislocation through the base aspects of all 5 metatarsals.

ABSTRACT: The cardinal feature of irritable bowel syndrome (IBS) is abdominal pain or discomfort associated with altered bowel habits. Because no serologic marker or structural abnormality exists, the diagnosis is based on clinical findings. A systematic symptom-based approach, including the Rome II criteria, ensures diagnostic accuracy. Determine whether a specific event-such as gastroenteritis, antibiotic use, or a food-borne illness-precipitated the IBS symptoms. Be alert for warning signs of cancer, infection, or inflammatory bowel disease, such as fever or unexplained weight loss. Only minimal laboratory testing is required; however, further evaluation may be warranted if a patient does not respond to treatment or loses weight, if the dominant symptom changes, or if other "red flags" are identified.
An 83-year-old woman is brought by her daughter for evaluation becauseof increasing confusion during the past few days. The patienthas early Alzheimer dementia, hypertension, and type 2 diabetes.

Ezetimibe/simvastatin (Vytorin)recently became available for thetreatment of high LDL cholesterollevels, as adjunctive therapy to dietarymodification, in patients withprimary hypercholesterolemia ormixed hyperlipidemia. This drug,from Merck/Schering-Plough Pharmaceuticals,inhibits the productionof cholesterol in the liver and blocksthe absorption of cholesterol in theGI tract, including cholesterol obtainedfrom food.
