Huge Infected Thrombus of Right Atrium Related to Hemodialysis Catheter / 대한신장학회지

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.

The Incidence and Clinical Course of Acute Renal Failure in Patients with Severe Acute Pancreatitis / 대한신장학회지

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.

Intracranial Hypotension with Spontaneous CSF Leakage in a Patient with Systemic Lupus Erythematosus / 대한류마티스학회지

Headaches are not only one of the 19 different neuropsychiatric syndromes in SLE but also the most common chief complaint of patients with neuropsychiatric lupus. Approximately 50% of patients with SLE are presumed to have neuropsychiatric phenomena during their illness. There're no specific serological, radiological or histological biomarkers to confirm the clinical diagnosis of neuropsychiatric lupus. Therefore, physicians tend to try controlling lupus activity especially when the origins of the headache in patients with lupus are difficult to define. However, neuropsychiatric lupus can only be diagnosed after excluding other causes which is the point. A 47-year-old woman with lupus presented to the emergency department with the sudden onset of postural headache with nausea and vomiting. Through CSF tapping and CT myelography, intracranial hypotension with spontaneous CSF leakage was revealed. Her symptoms promptly improved after therapy using an epidural blood patch. Intracranial hypotension with spontaneous CSF leakage is rare disease, and it has never been reported in patients with SLE before. This case emphasizes the importance of finding out the origin of a headache in patients with lupus.

A Case of Pulmonary Thromboembolism in Crohn's Disease / 결핵및호흡기질환

Crohn's disease, a major form of inflammatory bowel disease (IBD), is a chronic inflammatory condition that is characterized by microvascular and macrovascular involvement. Some extraintestinal complications can occur due to chronic systemic inflammation in IBD. Among them, a pulmonary thromboembolism is a rare manifestation of IBD but is associated with a high morbidity and mortality. To our best of knowledge, there is only one case report of a pulmonary thromboembolism as a complication of Crohn's disease in Korea. We present another rare case of pulmonary thromboembolism as complication in a 25-year-old man with underlying Crohn's disease.
