We investigated the relationship between lactate clearance and outcome in patients surviving the first 48 hours after cardiac arrest. We conducted the study in the emergency department of an urban tertiary care hospital. We analyzed the data for all 48-hour survivors after successful resuscitation from cardiac arrest during a 10-year period. ⋯ Sensitivity for both end points was 31%. Lactate at 48 hours after cardiac arrest is an independent predictor of mortality and unfavorable neurologic outcome. Persisting hyperlactatemia over 48 hours predicts a poor prognosis.

We review 170 previously reported cases of sternoclavicular septic arthritis, and report 10 new cases. The mean age of patients was 45 years; 73% were male. Patients presented with chest pain (78%) and shoulder pain (24%) after a median duration of symptoms of 14 days. ⋯ Computed tomography or magnetic resonance imaging should be obtained routinely to assess for the presence of chest wall phlegmon, retrosternal abscess, or mediastinitis. If present, en-bloc resection of the sternoclavicular joint is indicated, possibly with ipsilateral pectoralis major muscle flap. Empiric antibiotic therapy may need to cover methicillin-resistant Staphylococcus aureus (MRSA).

Cardiovascular infections due to Salmonella enterica are infrequently reported, so their clinical features, prognosis, and optimal treatment are not completely known. Mortality associated with aortitis and endocarditis caused by nontyphoidal Salmonella remains exceedingly high. In this review of cases of cardiovascular infections due to Salmonella enterica studied in 2 hospitals in Madrid, we tried to assess the clinical manifestations and the procedures leading to diagnosis in addition to treatment and outcome. ⋯ Optimal treatment of patients with endocarditis occurring on ventricular aneurysms must include resection of the aneurysmal sac. Salmonella endocarditis can be successfully treated with antimicrobials alone. Valve replacement should be reserved for patients with cardiac failure or persisting sepsis, and for those who relapse after discontinuation of antimicrobial therapy.

Review Case Reports Comparative Study
Clinical features and metabolic and autoimmune derangements in acquired partial lipodystrophy: report of 35 cases and review of the literature.
We describe clinical features, body fat distribution, and prevalence of metabolic abnormalities in 35 patients with acquired partial lipodystrophy (APL) seen by us over 8 years, and also review 220 cases of APL described in the literature. Based on the review and our experience, we propose that the essential diagnostic criterion for APL is the gradual onset of bilaterally symmetrical loss of subcutaneous fat from the face, neck, upper extremities, thorax, and abdomen, in the "cephalocaudal" sequence, sparing the lower extremities. Analysis of the pooled data revealed that female patients were affected approximately 4 times more often than males. ⋯ Treating the cosmetic disfigurement by surgical procedures has yielded inconsistent results. The use of thiazolidinediones to treat fat loss in patients with APL remains anecdotal. Prognosis is mainly determined by renal insufficiency due to MPGN.

We conducted the current study to search for subclinical atherosclerosis in patients with rheumatoid arthritis (RA) without clinically evident atherosclerosis or its complications who had been treated for a long duration, and to assess whether demographic or clinical factors affect the development of atherosclerotic disease. Forty-seven white patients fulfilling the 1987 American College of Rheumatology classification criteria for RA were recruited from Hospital Xeral-Calde, Lugo, Spain. Patients were required to have been treated for at least 5 years, including current treatment with 1 or more disease-modifying antirheumatic drugs. ⋯ Also, RA patients with carotid plaques had a significantly longer disease duration (mean, 21.0 yr) and more extraarticular manifestations (63%) than those without plaques (mean, 12.7 yr and 26%, respectively). Age at the time of the study and disease duration were the best predictive factors for the development of severe morphologic expression of atherosclerotic disease. The present study confirms an increased frequency of severe subclinical atherosclerotic findings in long-term actively treated RA patients from northwest Spain.
