[Irradiation for invasive malignant thymoma led a remission of refractory minimal change nephrotic syndrome: a case report].

A 46-year-old man was diagnosed as malignant thymoma, and was treated with chemotherapy and radiotherapy in 2003. On June 2004, he had edema of his legs and nephrotic syndrome (NS). As renal biopsy revealed a minor glomerular abnormality, he was diagnosed as minimal change nephrotic syndrome (MCNS). Intravenous steroid therapy of 500 mg/day for 3 days, following oral administration of 15 mg/day prednisolone and 75 mg cyclosporine twice a day was taken from July 2004. On July 2005, he went into remission of NS with 0.6 g/day proteinuria. On January 2008, NS relapsed with left pleural effusion. Chest CT and a biopsy specimen from left pleural mass lesion revealed the pleural invasion of malignant thymoma. Sixty Gray radiotherapy diminished the pleural metastatic lesion and also improved proteinuria from 6.6 g/day to 0.4 g/day. Though there have been a few case reports of MCNS concomitant with malignant thymoma, this is the first report that radiotherapy for metastatic malignant thymoma improved NS while diminishing the tumor.

[Laser treatment of patients with chronic glomerulonephritis]. / Lazernaia terapiia bol'nykh khronicheskim glomerulonephritis.

Helium-neon laser therapy of patients suffering from mixed and nephrotic glomerulonephritis demonstrated hypotensive, diuretic and fibrinolytic activity boosting clinical effects. The use of the new treatment method seems to be justified, since all the patients given laser therapy manifested pronounced resistance to the pathogenetic therapy carried out previously (glucocorticoids, cytostatics, hypotensive and diuretic drugs). The presence of diverse effects and lack of complications suggest a broader-scale use of laser therapy in nephrology. At present the authors are analyzing the ++patho-chemical bases of the therapeutic efficacy of laser therapy of patients suffering from chronic glomerulonephritis. The results will be reported in the next paper.
