Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis predominantly involving medium- or small-sized arteries, typically of the kidneys and other internal organs. Given the rarity of PAN and the variable clinical presentation, diagnosis is challenging and, to date, no definitive diagnostic marker has been identified. A patient diagnosed with immunoglobulin A nephropathy was observed to exhibit deterioration in renal function. To determine whether new structural abnormalities had developed, computed tomography scans of the kidneys, ureters, and bladder were obtained. Both kidneys exhibited multiple cortical defects, and a renal angiogram was performed to determine the cause. Angiography revealed partial obliteration of the left distal renal artery branches and multifocal extensive infarctions in both kidneys, and the patient was diagnosed with renal-limited PAN. Following steroid monotherapy, an improvement in renal function was observed. We believe that this case report may be helpful to physicians who assess and treat patients with suspected renal-limited PAN.

Contrary to the assumptions of Mundell-Fleming model, South Korean interest rates have moved decisively in sync with U.S. counterparts even after the country has adopted a floating exchange rate regime in 1999, keeping the gap in rates of the two countries more or less in a restrictive boundary. But the impact of U.S. rate increases on Korean rates has not been consistent due to changes in the transition channel such as trade, inflation, foreign exchange, and financial markets. The recent difference in the pace of rate increases in the two countries has widened the gap in the rates. The widening gap in domestic and U.S. rates while global inflationary pressure and private-sector debt remain high has deepened the trade-off not only between inflation and financial stability in monetary policy-making, but also between foreign exchange rate and financial (or interest rate) stability. The Bank of Korea has been flexible in rate policy while placing top priority in stabilizing prices and at the same time has been employing various micro measures to stabilize volatile foreign exchange and financial market from rises in rates at home and abroad. The mix of macro- and microeconomic policies have helped to ease the trade-off in policy goals and smoothen the transmission channel from rate policy. Due to the unprecedented complexities in economic conditions at home and abroad, monetary policy must be accompanied with various supplementary measures and stronger communication. We must continue to refer to the comprehensive economic policy frameworks suggested by the IMF and BIS to find the best policy mix and design for South Korea.
