Avascular Necrosis of the Femoral Head in Patient with Psoriatic Arthritis / 대한류마티스학회지

Psoriatic arthritis and avascular necrosis of the femoral head each are relatively common diseases. However, avascular necrosis of the femoral head in psoriatic arthritisis extremely rare disease and a few cases have been reported to date. It is suggested that the use of steroids or chemotherapeutic agents, hyperuricemia, alcohol abuse, immunologic disorders, coagulopathies are risk factors of the development of avascular necrosis of the femoral head in psoriatic arthritis. This report describes a 58-year-old female patient without any of forementioned risk factors who underwent total hip replacement for femoral head avascular necrosis associated with psoriatic arthritis.

A Case of Overlapping Syndrome of Primary IgA Nephropathy and Membranous Nephropathy / 대한신장학회잡지

We report a rare case of primary glomerular disease with overlapping IgA nephropathy and membranous nephropathy in a 52 year-old man. Clinically, The patient showed microscopic hematuria and proteinuria and had no underlying disorders such as hepatitis B, hepatitis C, drug exposure, SLE or other immunologic diseases. Histologically, glomeruli showed focal cellular proliferartione and electron deposits in the mesangium and concomittant subepithelial deposits. Immunofluorescence revealed IgA depositions in a mesangium and IgG depositions along the glomerular capillary walls, like those of typical membranous nephropathy. These findings suggest the primary glomerular disease overlapping of two different glomerular changes. The patient showed still persistent proteinuria, but have preserved renal function with administrations of ACE inhibitors and diuretics after two years.

Predictive value of troponin l and myoglobin in patients with unstable coronary artery disease / 대한내과학회지

BACKGROUND: Patients with unstable angina or non Q wave myocardial infarction still have an elevated risk for subsequent cardiac events. Therefore early assessment of the risk of future cardiac events is important. In this study, prognostic value of troponin l and myoglobin was evaluated and compared with other known early available risk indicators. METHODS: Serum troponin l and myoglobin were measured at presentation and 8 hours, 16 hours, and 24 hours thereafter in 126 patients with unstable angina (n=70) or non Q myocardial infarction (n=56) from Jan 1998, through Feb 2000. Echocardiography was performed with calculation of wall motion score index. The incidence of cardiac death or myocardial infarction was compared between patients with normal troponin l, myoglobin and abnormal ones, respectively. RESULTS: (1) At 6 months, 1 death (2.2%) and 1 myocardial infarction (2.2%) occured in the 45 unstable angina patients with normal troponin l compared with 3 deaths (12.0%) and 8 myocardial infarctions (32.0%) in the 25 unstable angina patients with elevated troponin l. (2) At 6 months, 1 death (1.7%) and 3 myocardial infarctions (5.2%) occured in the 58 unstable angina patients with normal myoglobin compared with 3 deaths (25.0%) and 6 myocardial infarctions (50.0%) in the 12 unstable angina patients with elevated myoglobin.(3) When the analysis was limited to patients with normal baseline troponin l (< or = 0.4 ng/dl: n=45), increased myoglobin level remained significantly associated with increased incidence of cardiac deaths or myocardial infarction compared with normal myoglobin level (16.7% vs 0%). (4) Together with age, diabetes, wall motion score index, troponin I and myoglobin levels were identified as independent prognostic variables for myocardial infarction or cardiac death in a multivariate logistic regression analysis. (5) The maximal troponin l and myoglobin value obtained during the first 24 hours provides independent and important prognostic information regardless of whether the patient is classified as having unstable angina or non Q wave myocardial infarction. CONCLUSION: The maximum troponin l and myoglobin obtained during the first 24 hours provides independent and important prognostic information in patients with unstable angina or non Q wave myocardial infarction.
