RESUMEN
Measles epidemic occurred in southern part of Fukushima Prefecture from April 2002 to July 2003. Public Iwase hospital in Sukagawa City was the central hospital in the measles epidemic area and 382 patients with measles were admitted to the hospital during the epidemic. Based on clinical records, age distribution, vaccination history, familiar infection and complications were retrospectively investigated. Moreover, the vaccination rates and their calculating methods in the area were compared and the problems on immunization against measles were discussed. As the result, we found that 1) measles epidemic centered on unvaccinated infants, 2) measles was still serious disease with many complications and sometimes fatal, 3) measles was highly infectious and there was no way for prevention except vaccination, 4) the actual condition of measles vaccination was not reflected exactly by the current calculating methods used for the local health reports by the Ministry of Health Labour and Welfare. For the prevention of measles epidemic, it is necessary to know the exact numbers of patients infected with measles and patients deceased due to measles, to calculate precise vaccination rate, and to form the consensus among parents, physicians and administrators to control measles epidemic by the vaccination.

OBJECTIVE: There have been only a few studies concerning oral prednisolone and mizoribine therapy for diffuse IgA nephritis (IgAN). We evaluated the efficacy of prednisolone and mizoribine therapy for diffuse IgAN. METHODS: We enrolled 34 patients who had been diagnosed as having diffuse IgAN with severe proteinuria during the period from 1992 to 1999. Following diagnostic renal biopsy, the patients were treated with prednisolone, mizoribine, warfarin and dilazep dihydrochloride. The clinical features, laboratory data and pathological findings between pre- and post-therapy were investigated. RESULTS: The mean urinary protein excretion after 6 months of treatment had decreased significantly compared to pre-therapy. The incidence of hematuria in post-therapy was lower than that of pre-therapy. The grading index decreased significantly from 4.8 +/- 2.1 at the first biopsy to 2.3 +/- 1.7 at the second biopsy (p < 0.001) and the staging index decreased significantly from 4.1 +/- 1.9 at the first biopsy to 2.7 +/- 2.4 at the second biopsy (p < 0.05). Macrophage infiltration and alpha-smooth muscle actin-positive cells in the glomerulus and interstitial region decreased significantly in post-therapy compared with pre-therapy. At the most recent follow-up, none of the 34 patients had renal insufficiency. CONCLUSIONS: Our study suggested that prednisolone and mizoribine therapy is effective for those patients with the risk of progression of IgAN.
