    ABSTRACT: Corticosteroids used for chronic obstructive pulmonary disease (COPD) exacerbations can cause hyperglycemia in hospitalized patients, and hyperglycemia may be associated with increased mortality, length of stay (LOS), and re-admissions in these patients. We did three retrospective studies using charts from July 2008 through June 2009, January 2006 through December 2010, and October 2010 through March 2011. We collected demographic and clinical information, laboratory results, radiographic results, and information on LOS, mortality, and re-admission. Glucose levels did not predict outcomes in any of the studied cohorts, after adjustment for covariates in multivariable analysis. The first database included 30 patients admitted to non-intensive care unit (ICU) hospital beds. Six of 20 non-diabetic patients had peak glucoses above 200 mg/dl. Nine of the ten diabetic patients had peak glucoses above 200 mg/dl. The maximum daily corticosteroid dose had no apparent effect on the glucose levels. The second database included 217 patients admitted to ICUs. The initial blood glucose was higher in patients who died than those who survived using bivariate analysis (P = 0.015; odds ratio, OR, 1.01) but not in multivariable analysis. Multivariable logistic regression analysis also demonstrated that glucose levels did not affect LOS. The third database analyzing COPD re-admission rates included 81 patients; the peak glucose levels were not associated with re-admission. Our data demonstrate that COPD patients treated with corticosteroids developed significant hyperglycemia, but the increase in blood glucose levels did not correlate with the maximum dose of corticosteroids. Blood glucose levels were not associated with mortality, LOS, or re-admission rates.

    ABSTRACT: Atrial fibrillation (AF) is the most common arrhythmia in older adults with a prevalence of 9 % in adults aged 80 years or older. AF patients have a five times greater risk of developing stroke than the general population. Using anticoagulants for stroke prevention in the elderly becomes a challenge because both stroke and bleeding complications increase with age. CHA2DS2-VASc and HAS-BLED scores are currently used as stroke and bleeding risk evaluations. When the HAS-BLED score is 3 or higher, caution and efforts to correct reversible risk factors are advised. Regardless of the HAS-BLED score, warfarin or novel oral anticoagulants are a IIa recommendation for CHA2DS2-VASc of 1, except for a score of 1 for females, and a IA recommendation for the score of 2 or higher. Aspirin is no longer recommended for AF thromboprophylaxis. In an elderly patient, lenient rate control is preferred over rhythm control owing to fewer adverse drugs effects and hospitalizations. When rhythm control is needed, dronedarone is a new antiarrhythmic drug that can be considered in patients who have paroxysmal AF and no history of heart failure. Although less efficacious than amiodarone, dronedarone has a fewer thyroid, neurologic, dermatologic, and ocular side effects than amiodarone.

    ABSTRACT: Alcohol and illicit drug use seem to compound every aspect of health, with cardiac and infectious complications as no exceptions. Not spared from the influence of alcohol and illicit drug use is the subject of infective endocarditis. This study assesses the prevalence of disease and risk of complications in patients with infective endocarditis who used alcohol, illicit drugs, or illicit drugs and alcohol. Medical records of the patients diagnosed with infective endocarditis were retrospectively reviewed. The study showed no causation between alcohol intake and prevalence of infective endocarditis but demonstrated significant decreased cardiac function, increased vegetation size, and incidence of embolic complications among drug and/or alcohol users compared to nondrug/alcohol users.

    ABSTRACT: A 57-year-old man presented with sudden onset of leg pain, right-sided weakness, aphasia, confusion, drooling, and severe lactic acidosis (15 mmol/L). He had normal peripheral pulses and demonstrated no pain, pallor, poikilothermia, paresthesia, or paralysis. Empiric antibiotics, aspirin, full-dose enoxaparin, and intravenous fluid were initiated. Lactic acid level decreased to 2.5 mmol/L. The patient was subsequently extubated and was alert and oriented with no complaints of leg or abdominal pain. Unexpectedly, the patient developed cardiac arrest, rebound severe lactic acidosis (8.13 mmol/L), and signs of acute limb ischemia. Emergent computed tomography of the aorta confirmed infrarenal aortoiliac thrombosis. Transient leg pain and transient severe lactic acidosis can be unusual presentations of severe infrarenal aortoiliac stenosis. When in doubt, vascular studies should be implemented without delay to identify this catastrophic diagnosis.

    ABSTRACT: A 52-year-old unvaccinated and splenectomized man presented with fever, altered sensorium, bilateral flank pain and chest discomfort accompanied with paroxysmal atrial fibrillation with a rapid ventricular response. An abdominal computed tomography scan was performed, which revealed a right renal infarct and splenosis. Transthoracic echocardiography was performed, which demonstrated an echodense structure on the mitral valve with mitral regurgitation and a vegetation on the aortic valve with aortic regurgitation. Subsequently, he was found to have pneumococcal infective endocarditis, pneumococcal pneumonia and bacterial meningitis, namely Austrian syndrome. He underwent an early aortic valve and mitral valve repair but still had a poor clinical outcome. Renal infarction has a mortality of approximately 13.2%, which is strongly influenced by the underlying diseases and infectious complications. Medical and surgical treatment initiated in a timely manner is often inadequate. The authors report the first case of Austrian syndrome presenting with renal infarction as a clue to an embolic event associated with infective endocarditis in this study.

    ABSTRACT: The Centers for Medicare and Medicaid Services has identified early rehospitalization of patients with chronic obstructive pulmonary disease (COPD) exacerbations as a performance measure for hospital care. We retrospectively reviewed patients with COPD who were admitted to University Medical Center, Lubbock, Texas, USA, between October 2010 and March 2011. There were 81 COPD patients with 103 hospitalizations. The mean age was 73.9 years. Pulmonary function tests using the Global initiative for chronic Obstructive Lung Disease criteria had been done in 36 patients (44.4%) and revealed 1 mild (2.8%), 7 moderate (19.4%), 20 severe (55.6%), and 8 very severe (22.2%) cases. Only 38.4% of the patients had prior influenza vaccine. Most patients were treated with antibiotics (81.8%) and corticosteroids (87.9%). The mean length of stay was 4.9 days, and 4 patients died. Most of the patients were discharged home (63.6%) with a median follow-up interval of 14 days. Thirty-two percent did not have long-acting bronchodilators and/or inhaled corticosteroids prescribed on discharge. There were 14 early rehospitalizations within 30 days. Logistic regression analysis indicated that a history of coronary artery disease (odds ratio (OR) 6.4, 95% confidence interval (CI) 1.1-37.4) and unilateral pulmonary infiltrates (OR 12.8, 95% CI 1.9-86.4) significantly increased the early rehospitalization rates. Acute exacerbations of COPD in patients with a history of ischemic heart disease or unilateral pulmonary infiltrates are at increased risk for early readmission. These risk factors should be identified during hospitalization; early follow-up or other interventions may reduce readmissions. Influenza vaccine, maintenance bronchodilators and/or inhaled corticosteroids, and pulmonary function tests were underused, and these standards of care should be provided to improve care.
