Summary:Allogeneic bone marrow transplantation (BMT) has been successfully used for the treatment of several hematological malignancies; however, it is associated with transplant-related toxicities such as functional impairment and muscle weakness. In order to analyze how an exercise program may influence muscle strength in patients undergoing BMT, we carried out a prospective study assessing patients from the pre-BMT phase to 16 weeks post-BMT. In all, 18 patients underwent three trials: (1) pre-BMT, (2) after marrow engraftment, and (3) 6 weeks after trial 2. After trial 2, the patients were randomized in a control group (CG) or treatment group (TG), which received a 6-week exercise program with active exercise, muscle stretching and treadmill walking. The results obtained in trial 1 showed similar values for CG and TG, as both groups had muscle strength lower than normal patterns based on data concerning age, sex and weight. In trial 2, CG and TG showed similarly decreased values. In trial 3, TG showed values higher than CG for all muscle groups tested. These results suggest that the exercise program was efficient in promoting an increase of muscle strength after allogeneic BMT.
Purpose:To assess the public hospitalization rate due to stone disease in a large developing nation for a 15-year period and its association with socio-demographic data.Materials and Methods:A retrospective database analysis of hospitalization rates in the Brazilian public health system was performed, searching for records with a diagnosis code of renal/ureteral calculi at admission between 1998–2012. Patients managed in an outpatient basis or private care were excluded. Socio-demographic data was attained and a temporal trend analysis was performed.Results:The number of stone-related hospitalizations increased from 15.7%, although the population-adjusted hospitalization rate remained constant in 0.04%. Male:female proportion among hospitalized patients was stable (49.3%:50.7% in 1998; 49.2%:50.8% in 2012), though there was a significant reduction in the prevalence of male hospitalizations (−3.8%;p=0.041). In 2012, 38% of hospitalized patients due to stone disease had 40–59 years-old. The ≥80 years-old strata showed the most significant decrease (−43.44%;p=0.022), followed by the 20–39 (−23.17%;p<0.001) and 0–19 years-old cohorts (−16.73%;p=0.012). Overall, the lowest relative hospitalization rates were found for yellow and indigenous individuals. The number of overweight/obese individuals increased significantly (+20.6%), accompanied by a +43.6% augment in the per capita income. A significant correlation was found only between income and obesity (R=0.64;p=0.017).Conclusions:The prevalence of stone disease requiring hospitalization in Brazil remains stable, with a balanced proportion between males and females. There is trend for decreased hospitalization rates of male, <40 and ≥80 years-old individuals. Obesity and income have a more pronounced correlation with each other than with stone disease.
Trends of stone disease surgical management in the public health system of Brazil follow worldwide tendencies toward less invasive treatment modalities.
Aims
Evaluate the efficacy of biofeedback and parassacral electric nerve stimulation (TENS) for the treatment of children with lower urinary tract (LUT) dysfunction.
Methods
A prospective, randomized study was approved by our Hospital Ethics Committee. We enrolled 64 children, 43 girls and 21 boys, average age of 9.39 years. The initial evaluation consisted of history, physical examination, urine analyses, voiding diary, uroflow, and ultrasound. Dysfunction voiding symptom score (DVSS) questionnaires were applied pre‐ and post‐treatment. The children were divided into two treatment groups independent of the predominant type of voiding dysfunction (dysfunctional or overactive bladder): biofeedback group and TENS group. The criteria for assessing the effectiveness of the techniques was the resolution of daytime and nighttime symptoms including urinary leakage, improvements in voiding diary, DVSS, and changes in uroflow. After 6 months, the children were reassessed with the same work‐up of baseline.
Results
Regarding daytime symptoms, results for complete response were similar between the two groups (P = 0.483); 54.9% of children treated by the biofeedback group and 60.6% in the TENS group. The same have been observed in the nighttime incontinence with complete resolutions in 29.6% and 25%, respectively (
P = 0.461). Analyzing the voiding diary, uroflow and DVSS questionnaires both groups had significant improvement (
P = 0.001) after treatment. The biofeedback group required fewer sessions than TENS group, 10.9 and 18.1, respectively (
P < 0,001).
Conclusions
Both biofeedback and the TENS are equally effective for treating non‐neurogenic voiding dysfunction. Biofeedback seems to require a lower number of sessions to obtain similar results of the TENS.
Laparoscopy seems to be safe and effective for management of failed pyeloplasty in children. Based on our data, reoperation is as safe and effective as primary pyeloplasty.
