There has been an increase in the use of central venous catheters for temporary hemodialysis. Infected thrombus of right atrium is a rare but life-threatening complication of the central venous catheterization. A 35-year-old female hemodialysis patient was admitted with fever and dyspnea. She had been inserted tunneled hemodialysis catheter 2 months before. Blood cultures revealed methicillin- resistant Staphylococcus aureus. Chest CT showed multi-focal pneumonia and 4 cm sized huge thrombus in the right atrium. Echocardiography demonstrated same thrombus attached to the catheter tip in the right atrium. The catheter could not be removed because of high risk of pulmonary thromboembolism. Despite intravenous vancomycin treatment, the patient died from esophageal varix bleeding.

PURPOSE: Although acute renal failure (ARF) commonly develops in patients with severe acute pancreatitis (SAP), the impact of ARF on disease severity is rarely reported in Korea. This study was performed to compare the clinical findings, morbidity and mortality between SAP patients with and without ARF. METHODS: We retrospectively evaluated the medical records of 102 patients with SAP between january 2001 and June 2008 in 3 hospitals. We investigated the incidence and clinical course of ARF in SAP patients. Then, we compared morbidity and mortality between the patients with ARF and normal renal function (NRF). RESULTS: Of the total 102 SAP patients, ARF was observed in 39 patients (38.2%). The peak serum creatinine level in ARF patients was 4.5+/-2.3 mg/dL. Eight of the 39 ARF patients (20.5%) received hemodialysis and ten patients (25.6%) died. When compared to NRF patiens, ARF patients (n=39) had higher incidence of dyspnea (17.9% vs 3.2%, p=0.011), loss of consciousness (17.9% vs 1.6%, p=0.003), and APACHE II scores more than 8 (92.3% vs 0%, p<0.001). The ARF group had also higher incidences of sepsis (35.9% vs 7.9%, p<0.001), multiorgan failure (15.4% vs 0%, p=0.001), respiratory failure (28.2% vs 4.7%, p=0.001) and mortality (25.6% vs 3.2%, p=0.001). Multivariate analysis demonstrated thrombocytopenia, hemoconcentration, and high LDH as independent risk factors of ARF in SAP patients. CONCLUSION: The incidence of ARF was high (38.2%) and ARF patients showed higher morbidity and mortality, compared to NRF patients. We suggest that early management of ARF should be performed for reducing the mortality in SAP patients.

The purpose of this study was to establish a prediction rule for severe illness in adult patients hospitalized with pandemic influenza A (H1N1) 2009. At the time of initial presentation, the baseline characteristics of those with severe illness (i.e., admission to intensive care unit, mechanical ventilation, or death) were compared to those of patients with non-severe illnesses. A total of 709 adults hospitalized with pandemic influenza A (H1N1) 2009 were included: 75 severe and 634 non-severe cases. The multivariate analysis demonstrated that altered mental status, hypoxia (PaO2/FiO2 < or = 250), bilateral lung infiltration, and old age (> or = 65 yr) were independent risk factors for severe cases (all P < 0.001). The area under the ROC curve (0.834 [95% CI, 0.778-0.890]) of the number of risk factors were not significantly different with that of APACHE II score (0.840 [95% CI, 0.790-0.891]) (P = 0.496). The presence of > or = 2 risk factors had a higher sensitivity, specificity, positive predictive value and negative predictive value than an APACHE II score of > or = 13. As a prediction rule, the presence of > or = 2 these risk factors is a powerful and easy-to-use predictor of the severity in adult patients hospitalized with pandemic influenza A (H1N1) 2009.
