Purpose: Physical interventions during subacute rehabilitation have potential to improve functional recovery. This study explored the perspectives of children and adolescents with acquired brain injury (ABI) and their parents with respect to physical rehabilitation during the subacute phase., Methods: Thirteen children and adolescents with ABI and their parents were included and interviewed using semi-structured interviews. Interview transcripts were analysed using inductive thematic analysis approach., Results: Six themes were identified: 1) beliefs of physical rehabilitation, 2) content of physical rehabilitation, 3) tailored care, 4) impact of context, 5) communication and 6) transition. The importance of intensive physical practice was widely supported. The positive can-do mentality was emphasised to create an atmosphere of hope, meaning that every effort would be made to achieve maximum recovery. Intensive involvement of parents is considered essential during subacute rehabilitation including an open and mutual dialogue about the focus of rehabilitation, therapy goals and future participation in their own environment., Conclusions: Our findings highlight the need for an intensive rehabilitation approach, tailored to the individual's needs. The perspectives of children and adolescents and their parents in our study contribute to a better understanding of factors that are important for optimal recovery through physical rehabilitation during the subacute phase.

Approximately 25% of the patients with muscle-invasive bladder cancer (MIBC) who are clinically node negative have occult lymph node metastases at radical cystectomy (RC) and pelvic lymph node dissection. The aim of this study was to evaluate preoperative CT-based radiomics to differentiate between pN+ and pN0 disease in patients with clinical stage cT2-T4aN0-N1M0 MIBC. Patients with cT2-T4aN0-N1M0 MIBC, of whom preoperative CT scans and pathology reports were available, were included from the prospective, multicenter CirGuidance trial. After manual segmentation of the lymph nodes, 564 radiomics features were extracted. A combination of different machine-learning methods was used to develop various decision models to differentiate between patients with pN+ and pN0 disease. A total of 209 patients (159 pN0; 50 pN+) were included, with a total of 3153 segmented lymph nodes. None of the individual radiomics features showed significant differences between pN+ and pN0 disease, and none of the radiomics models performed substantially better than random guessing. Hence, CT-based radiomics does not contribute to differentiation between pN+ and pN0 disease in patients with cT2-T4aN0-N1M0 MIBC.

Purpose: Subjective and objective results were assessed after laser prostatectomy with the Urolase fiber at 5 different centers in The Netherlands., Materials and Methods: Patients were evaluated with the international prostatic symptom score questionnaire, uroflowmetry and post-void residual volume measurements. Urodynamic investigations with pressure-flow analysis were performed at 2 centers., Results: Data for 233 patients were evaluated. Overall significant improvement in mean international prostatic symptom score, maximum flow, post-void residual and urodynamic parameters was noted. Differences in outcome among the centers may be due to variation of technique or different selection criteria. Postoperative morbidity was significant, with irritative voiding complaints for 4 to 6 weeks in up to 50% of all patients and urinary tract infections in 21.1%., Conclusions: Laser prostatectomy results in subjective and objective improvement, which is operator independent. Despite the observation that perioperative (intraoperative and immediate postoperative) morbidity seems less severe compared to transurethral resection of the prostate, there is a shift toward greater postoperative morbidity.

Objectives: The aim of this study was the assessment of the quality of side-firing fibers that are being used for laser prostatectomy, either by a laser light transmission measurement or by visual inspection., Methods: A power meter (Aquarius) was developed to measure the actual power transmitted through a side-firing fiber and delivered to the prostatic tissue. The power measurements were performed under clinical conditions, that is, under water and at relatively high input power. Furthermore, a protocol was developed for visual inspection of the fibers. Eight types of side-firing fibers were measured before use. Before and after a procedure, three fiber types were measured: ProLase II (28 samples), UltraLine (23 samples), and UroLase (44 samples). All these fibers were used in standard treatment protocols., Results: At 60 W the transmission of new fibers (not used) ranged between 49% and 83% when compared to a bare fiber. After use, a large variation was found in transmitted power between different samples of one device. A correlation with total transmitted power was not present. At higher power input, vapor bubbles are generated at the tip of the fibers. Depending on the fiber design, these bubbles have a major impact on the transmission. Only for the UroLase fiber was there a significant correlation between visual inspection and the transmission of used samples at 10, 20, and 40 W., Conclusions: The transmission strongly varies between fibers and between different samples of one fiber during clinical use. Moreover, the transmission does not correlate with visual inspection. A power measurement during a clinical treatment will contribute to a more controlled procedure and to a better comparison of clinical laser prostatectomy studies.

Lower urinary tract symptoms caused by benign prostatic obstruction (BPO) has been, and still is, treated by performing a transurethral or open prostatectomy. During the last decade many alternative treatments have been introduced and one of these new modalities uses laser energy in the ablation of prostatic tissue. When reviewing the literature on laser treatment of the prostate using side-firing laser devices, this procedure has proven to be safer and almost as effective as transurethral resection of the prostate (TURP). But although severe complications as TURP syndrome, incontinence and the need for blood transfusions have not occurred during laser prostatectomies, morbidity consisting of irritative voiding compliants and long catheterization duration have been reported by several authors. With the development of the contact laser probe and the interstitial laser technique some of these problems are (partly) solved, but also these new techniques still have considerable limitations which may disappear with future developments of newer laser probes and refining of existing laser techniques. Also, a better understanding and control in the laser-tissue interaction may help in reducing morbidity and inducing a more effective treatment.

Objective: To determine if bladder outlet obstruction can be adequately relieved after laser prostatectomy., Patients and Methods: Since November 1992, a total of 105 patients underwent laser treatment of the prostate because of complaints related to benign prostatic enlargement (BPE). To date, urodynamic data from a study of pressure flow analysis are available for 79 patients both at baseline and at 6 months after treatment. Patients were evaluated using changes in symptoms (IPSS symptom score), peak flow rate (Qmax), post-voiding residual volume (PVR), detrusor pressure at maximum flow (Pdet at Qmax), and the linear passive urethral resistance relation (LPURR). Moreover, patients with minimal bladder outlet obstruction were compared to patients with severe bladder outlet obstruction., Results: There was a significant improvement in mean IPSS score from 21.3 at baseline to 5.3 at the 6-month follow-up. The Qmax improved from 7.9 mL/s to 17.8 mL/s, and the PVR decreased from 91.6 mL to 15.6 mL. At baseline, > 80% of the patients were considered obstructed according to the analysis of pressure flow, whereas 6 months after laser treatment, only 5% of the patients were still considered obstructed. A comparison of the outcome between minimally obstructed patients and severely obstructed patients showed comparable improvements., Conclusion: Laser therapy of the prostate was, according to urodynamic parameters, capable of relieving outlet obstruction and minimally obstructed patients also showed a significant relief of outlet obstruction.
