[Botulinic toxin type a in combined treatment of males with chronic pelvic pain syndrome in combination with bladder emptying dysfunction].

The efficacy of various treatment of chronic pelvic pain syndrome in combination with bladder emptying dysfunction was comparatively analysed for 31 male patients. Statistics show that current schemes of medication including antibacterial, nonsteroid anti-inflammatory drugs, alpha-adrenoblockers are not highly effective in such patients. Transrectal microwave hyperthermia is effective in males with chronic pelvic pain syndrome but the response is short - 3 months maximum. The highest and the longest effect in patients with chronic pelvic pain syndrome in combination with bladder emptying dysfunction was achieved after injections of 100 units of botulinic toxin type A into the cross-striated sphincter of the urethra.

[Use of Mabtera (rituximab) in treating patients with refractory courses of B-cell lymphoma, along with high-dose chemotherapy and autologous transplantation of hematopoietic stem cells]. / Primenenie mabtery (rituksimab) u bol'nykh refrakternym techeniem B-kletochnym limfom, poluchaiushchikh vysokodoznuiu khimoterapiiu s autologichenoi transplanttatsiei kletok-predshestvennits gemopoéza.

AIM: To study efficacy of rituximab in patients with resistant B-cell lymphoma on high-dose chemotherapy. MATERIAL AND METHODS: From September 2000 to April 2002 we studied efficacy and tolerance of rituximab at different stages of high-dose chemotherapy. The treatment was given to 10 patients with histologically verified CD20+ non-Hodgkin's lymphoma: diffuse large-cell (n = 4), Berkitt's (n = 2), follicular (n = 3), mantle-cell (n = 1). Five patients with diffuse large-cell lymphoma and Berkitt's lymphoma had a primary resistant course of the disease, one patient with diffuse large-cell lymphoma had a refractory recurrence. Follicular and mantle-cell lymphomas were characterized by a resistant course and large tumor masses. The patients received 1-2 courses of induction chemotherapy with dexa-BEAM with collection of peripheral stem cells followed by high-dose chemotherapy (BEAM-9, CBV + mitoxantron-1) with transplantation of autologous stem blood cells. Rituximab infusion (375 mg/m2) was conducted before the collection of the stem cells, prior to high-dose chemotherapy and in posttransplantation period after recovery of hemopoiesis. RESULTS: 4 patients achieved complete remission, 3-partial remission, 2 had progression and 1-stabilization. In mean follow-up 11 (2-20) months 7 of 10 patients were alive, overall survival being 15 +/- 2.4 months (95% confidence interval 10-19.7), median was not reached. 5 patients are in complete remission: 2 of them without further treatment, 3-after progression and repeat therapy including rituximab and interferon-alpha or rotuximab and CHOP chemotherapy. CONCLUSION: The addition of rituximab can improve the results of high-dose chemotherapy of patients with non-Hodgkin's lymphoma resistant to standard doses of cytostatics. Repeat use of this drug can be effective in some patients with progression after high-dose chemotherapy with rituximab.
