Correction: Rule out pulmonary tuberculosis: clinical and radiographic clues for the internist.

In the article "Rule out pulmonary tuberculosis: Clinical and radiographic clues for the internist" (Curley CA. Cleve Clin J Med 2015; 82:32-38), on page 33, "Bacillus Calmette-Guérin vaccine" has been corrected to "BCG vaccine."

Rule out pulmonary tuberculosis: clinical and radiographic clues for the internist.

As tuberculosis rates decline in the United States, clinicians are less likely to consider it early in a patient's illness. Certain clinical and radiographic features increase the likelihood of tuberculosis. This review covers the clinical and radiographic features of tuberculosis, the initial evaluation of the patient, the use of airborne infection isolation, and the utility of new molecular techniques in diagnosing tuberculosis.

Diabetic foot infections.

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.

Promoting stroke-specific education.

Stroke is the most common cause of adult neurological disability in the UK. This article describes the reasons for the establishment of the UK Forum for Stroke Training and the Stroke-Specific Education Framework. It illustrates how these initiatives can be used to access a range of endorsed, stroke-specific courses to develop excellence in stroke care and multidisciplinary teamwork, as demanded by the Department of Health's National Stroke Strategy.

Prevention of VTE in orthopedic surgery patients: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines.

BACKGROUND: VTE is a serious, but decreasing complication following major orthopedic surgery. This guideline focuses on optimal prophylaxis to reduce postoperative pulmonary embolism and DVT. METHODS: The methods of this guideline follow those described in Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines in this supplement. RESULTS: In patients undergoing major orthopedic surgery, we recommend the use of one of the following rather than no antithrombotic prophylaxis: low-molecular-weight heparin; fondaparinux; dabigatran, apixaban, rivaroxaban (total hip arthroplasty or total knee arthroplasty but not hip fracture surgery); low-dose unfractionated heparin; adjusted-dose vitamin K antagonist; aspirin (all Grade 1B); or an intermittent pneumatic compression device (IPCD) (Grade 1C) for a minimum of 10 to 14 days. We suggest the use of low-molecular-weight heparin in preference to the other agents we have recommended as alternatives (Grade 2C/2B), and in patients receiving pharmacologic prophylaxis, we suggest adding an IPCD during the hospital stay (Grade 2C). We suggest extending thromboprophylaxis for up to 35 days (Grade 2B). In patients at increased bleeding risk, we suggest an IPCD or no prophylaxis (Grade 2C). In patients who decline injections, we recommend using apixaban or dabigatran (all Grade 1B). We suggest against using inferior vena cava filter placement for primary prevention in patients with contraindications to both pharmacologic and mechanical thromboprophylaxis (Grade 2C). We recommend against Doppler (or duplex) ultrasonography screening before hospital discharge (Grade 1B). For patients with isolated lower-extremity injuries requiring leg immobilization, we suggest no thromboprophylaxis (Grade 2B). For patients undergoing knee arthroscopy without a history of VTE, we suggest no thromboprophylaxis (Grade 2B). CONCLUSIONS: Optimal strategies for thromboprophylaxis after major orthopedic surgery include pharmacologic and mechanical approaches.

New guidelines: what to do about an unexpected positive tuberculin skin test.

The 2000 recommendations for tuberculosis testing from the American Thoracic Society and the Centers for Disease Control and Prevention advocate a shift in focus from screening the general population to testing only patients at increased risk of developing tuberculosis.
