Multicenter Study
Epidemiology of paediatric renal stone disease in the UK.
The previous epidemiological study of paediatric nephrolithiasis in Britain was conducted more than 30 years ago. ⋯ There has been a shift in the epidemiology of paediatric renal stone disease in the UK over the past 30 years. Underlying metabolic causes are now the most common but can be masked by coexisting urinary tract infection. Treatment has progressed, especially surgically, with sophisticated minimally invasive techniques now employed. All children with renal stones should have a metabolic screen.

Multicenter StudyIn vivo T cell depletion with low-dose rabbit antithymocyte globulin results in low transplant-related mortality and low relapse incidence following unrelated hematopoietic stem cell transplantation.
Stem cell transplantation from unrelated donors is associated with an increased risk of graft failure and graft-versus-host disease (GVHD). Addition of pretransplant antithymocyte globulin (ATG), although reducing the risk of graft rejection and GVHD, bears the risk of overimmunosuppression, resulting in an increased relapse rate and transplant-related mortality. Therefore, we evaluated in 21 consecutive patients receiving unrelated stem cell grafts from either HLA-matched (38%) or -mismatched (62%) donors whether low-dose rabbit ATG added to cyclosporin A and methotrexate at a total dose of 3.5 mg/kg for HLA-identical and 5.0 mg/kg for HLA-mismatched transplants given in two divided doses on days -2 and -1 provides sufficient immunosuppression for prevention of GVHD and graft rejection but is associated with an acceptable risk of relapse and transplant-related mortality. ⋯ Transplant-related mortality was 16 +/- 15% (95% CI) at day + 100 and 25 +/- 19% (95% CI) at 1 year after the transplant. The data presented show that pretransplant in vivo T cell depletion with low-dose rabbit ATG results in a low transplant-related mortality due to a low incidence of severe acute and chronic GVHD and a low relapse rate. To find out the optimal rabbit ATG dose in the unrelated stem cell transplantation setting, further dose-finding studies comparing high- and low-dose regimens are necessary.

The posttreatment prostate-specific antigen (PSA) bounce phenomenon has been recognized in at least 20% of all patients treated with radiation. The purpose of the current report was to determine if there was a difference in biochemical and clinical control between the bounce and nonbounce (NB) patients using pooled data on 4839 patients with T1-2 prostate cancer treated with external beam radiation therapy (RT) alone at 9 institutions between 1986 and 1995. ⋯ Patients treated with external beam radiation therapy alone who experience a posttreatment PSA bounce have increased risk of BF. However, this did not translate into a difference in clinical failure with the available follow-up in the current study.

Multicenter Study Observational StudyORBIT (Outcome and Retention Rate of Biologic Treatments for Psoriasis): A retrospective observational study on biologic drug survival in daily practice.
Biologic drug survival in psoriasis reflects long-term performance in real-life settings. Previous studies have yielded inconsistent results. ⋯ These findings can facilitate the daily treatment of psoriatic patients and promote long-term effectiveness of biologic therapies.

Intermittent androgen suppression for locally advanced and metastatic prostate cancer: preliminary report of a prospective multicenter study.
To clarify the effect of intermittent androgen suppression on the time to androgen-independent progression and changes in quality of life (QOL). ⋯ Our interim analysis indicated that QOL is remarkably improved during the off-treatment period. Intermittent androgen suppression would be a viable option for treatment of advanced prostate cancer, although a randomized controlled study is required to determine whether intermittent androgen suppression prolongs the time to androgen-independent cancer. We will continue follow-up in this study to a minimum of 3 years.
