AHA and ACC Outline Approaches to Coronary Disease Risk Assessment - Practice Guidelines
ABSTRACT: Transient ischemic attack is defined as transient neurologic symptoms without evidence of acute infarction. It is a common and important risk factor for future stroke, but is greatly underreported. Common symptoms are sudden and transient, and include unilateral paresis, speech disturbance, and monocular blindness. Correct and early diagnosis of transient ischemic attack versus mimicking conditions is important because early interventions can significantly reduce risk of future stroke. Nonspecific symptoms and gradual onset are more likely with mimics than with true transient ischemic attacks. Transient ischemic attacks are more likely with sudden onset, focal neurologic deficit, or speech disturbance. Urgent evaluation is necessary in patients with symptoms of transient ischemic attack and includes neuroimaging, cervicocephalic vasculature imaging, cardiac evaluation, blood pressure assessment, and routine laboratory testing. The ABCD2 (age, blood pressure, clinical presentation, diabetes mellitus, duration of symptoms) score should be determined during the initial evaluation and can help assess the immediate risk of repeat ischemia and stroke. Patients with higher ABCD2 scores should be treated as inpatients, whereas those with lower scores are at lower risk of future stroke and can be treated as outpatients.
ABSTRACT: Interventions following a transient ischemic attack are aimed at preventing a future episode or stroke. Hypertension, current smoking, obesity, physical inactivity, diabetes mellitus, and dyslipidemia are all well-known risk factors, and controlling these factors can have dramatic effects on transient ischemic attack and stroke risk. For patients presenting within 48 hours of resolution of transient ischemic attack symptoms, advantages of hospital admission include rapid diagnostic evaluation and early intervention to reduce the risk of stroke. For long-term prevention of future stroke, the American Heart Association/American Stroke Association recommends antiplatelet agents, statins, and carotid artery intervention for advanced stenosis. Aspirin, extended-release dipyridamole/aspirin, and clopidogrel are acceptable first-line antiplatelet agents. Statins have also been shown to reduce the risk of stroke following transient ischemic attack, with maximal benefit occurring with at least a 50 percent reduction in low-density lipoprotein cholesterol level or a target of less than 70 mg per dL (1.81 mmol per L). For those with transient ischemic attack and carotid artery stenosis, carotid endarterectomy is recommended if stenosis is 70 to 99 percent, and perioperative morbidity and mortality are estimated to be less than 6 percent.

Diabetic Foot Infections - Article
ABSTRACT: Diabetic foot infection, defined as soft tissue or bone infection below the malleoli, is the most common complication of diabetes mellitus leading to hospitalization and the most frequent cause of nontraumatic lower extremity amputation. Diabetic foot infections are diagnosed clinically based on the presence of at least two classic findings of inflammation or purulence. Infections are classified as mild, moderate, or severe. Most diabetic foot infections are polymicrobial. The most common pathogens are aerobic gram-positive cocci, mainly Staphylococcus species. Osteomyelitis is a serious complication of diabetic foot infection that increases the likelihood of surgical intervention. Treatment is based on the extent and severity of the infection and comorbid conditions. Mild infections are treated with oral antibiotics, wound care, and pressure off-loading in the outpatient setting. Selected patients with moderate infections and all patients with severe infections should be hospitalized, given intravenous antibiotics, and evaluated for possible surgical intervention. Peripheral arterial disease is present in up to 40% of patients with diabetic foot infections, making evaluation of the vascular supply critical. All patients with diabetes should undergo a systematic foot examination at least once a year, and more frequently if risk factors for diabetic foot ulcers exist. Preventive measures include patient education on proper foot care, glycemic and blood pressure control, smoking cessation, use of prescription footwear, intensive care from a podiatrist, and evaluation for surgical interventions as indicated.
