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.

Neurologic involvement occurs in approximately 20% of patients with primary Sjögren syndrome (SS). However, the diagnosis of SS with neurologic involvement is sometimes difficult, and central nervous system (CNS) manifestations have been described rarely. We conducted the current study to describe the clinical and laboratory features of SS patients with neurologic manifestations and to report their clinical outcome. ⋯ Screening for SS should be systematically performed in cases of acute or chronic myelopathy, axonal sensorimotor neuropathy, or cranial nerve involvement. The outcome is frequently severe, especially in patients with CNS involvement. Our study also underlines the efficacy of cyclophosphamide in myelopathy and multiple neuropathy occurring during SS.

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.
