Sacral Neuromodulation for Refractory Lower Urinary Tract Dysfunction: Results of a Nationwide Registry in Switzerland

OBJECTIVE: To assess the efficacy and safety of sacral neuromodulation (SNM) in patients with refractory lower urinary tract dysfunction in Switzerland based on a nationwide registry. PATIENTS AND METHODS: A total of 209 patients (181 females, 28 males) underwent SNM testing between July 2000 and December 2005 in Switzerland. Subjective symptom improvement, bladder/pain diary variables, adverse events, and their management were prospectively registered. RESULTS: SNM testing was successful (defined as improvement of more than 50% in bladder/pain diary variables) in 102 of 209 patients (49%). An implantable pulse generator (IPG) was placed in 91 patients (89% of all successfully tested and 44% of all tested patients). Of the IPG-implanted patients, 71 had urge incontinence, 13 nonobstructive chronic urinary retention, and 7 chronic pelvic pain syndrome. After a median follow-up of 24 mo, SNM was successful in 64 of the 91 IPG-implanted patients (70%) but failed in 27 patients. SNM was continued in 15 of the 27 patients considered failures, because following troubleshooting SNM response improved subjectively and the patients were satisfied. However, improvement in bladder/pain diary variables remained less than 50%. In the other 12 patients both the leads and the IPG were explanted. During the test phase and during/following IPG implantation, 6% (12 of 209) and 11% (10 of 91) adverse event rates and 1% (3 of 209) and 7% (6 of 91) surgical revision rates were reported, respectively. CONCLUSIONS: SNM is an effective and safe treatment for refractory lower urinary tract dysfunction. Adverse events are usually transient and can be treated effectively.

Laser-Sintern. Die Schluesseltechnologie des e-Manufacturing TM

e-Manufacturing™, das ist die schnelle, flexible und kostengünstige Fertigung von Produkten, Formen/Werkzeugen oder Modellen direkt aus elektronischen Daten. e-Manufacturing™ schließt Rapid Prototyping, Rapid Tooling oder Rapid Manufacturing ein, geht aber zugleich weit über den Gedanken der schnellen Verfügbarkeit hinaus. Zwar wird auch in Zukunft die schnelle Produktentwicklung eine immer wichtigere Rolle spielen, bei der e-Manufacturing™ für ein verkürztes Time to Market sorgt, Entwicklungskosten verringert und zur Risikominimierung beiträgt. Darüber hinaus entstehen aber auch neue Geschäftsmodelle, da Kleinserienproduktion, steigende Variantenvielfalt und eine individualisierte Produktion (Mass Customization) plötzlich möglich und wirtschaftlich sind und sich neue Logistikkonzepte wie (Spare) parts on demand entwickeln. Die neue Konstruktionsfreiheit des Laser-Sinterns ermöglicht neue Produktkonzepte. Minimale Einschränkungen durch das Fertigungsverfahren erlauben funktionelle Integration und die Fertigung des „Unmöglichen“, da kreisförmige und lineare Werkzeugbewegungen das Produktdesign nicht mehr beeinflussen bzw. limitieren. Auch die Fertigungskonzepte unterliegen einem Wandel und werden deutlich flexibler. Werkzeuglose Produktion, losgrößenangepasste Fertigung und dezentrale Fertigung on demand sind die Schlagworte der Zukunft. Der vorliegende Beitrag zeigt Beispiele für den erfolgreichen kommerziellen Einsatz von Laser-Sintern in allen Phasen des Produktlebenszyklus. Der Schwerpunkt liegt dabei auf der direkten Herstellung von Funktionsteilen in der Serienfertigung. Die entscheidenden Faktoren für eine erfolgreiche Einführung und Anwendung von e-Manufacturing™ werden diskutiert. Der Beitrag zeigt auf, wie die neuesten technologischen Innovationen im Laser-Sintern, speziell zur Produktivitätssteigerung, das Spektrum der Anwendungsfelder erweitern, in denen dieses Fertigungsverfahren kostengünstige Lösungen bietet.

Increased intraoperative epidural pressure in lumbar spinal stenosis patients with a positive nerve root sedimentation sign

Purpose The sedimentation sign (SedSign) has been shown to discriminate well between selected patients with and without lumbar spinal stenosis (LSS). The purpose of this study was to compare the pressure values associated with LSS versus non-LSS and discuss whether a positive SedSign may be related to increased epidural pressure at the level of the stenosis. Methods We measured the intraoperative epidural pressure in five patients without LSS and a negative SedSign, and in five patients with LSS and a positive SedSign using a Codman TM catheter in prone position under radioscopy. Results Patients with a negative SedSign had a median epidural pressure of 9 mmHg independent of the measurement location. Breath and pulse-synchronous waves accounted for 1–3 mmHg. In patients with monosegmental LSS and a positive SedSign, the epidural pressure above and below the stenosis was similar (median 8–9 mmHg). At the level of the stenosis the median epidural pressure was 22 mmHg. A breath and pulse-synchronous wave was present cranial to the stenosis, but absent below. These findings were independent of the cross-sectional area of the spinal canal at the level of the stenosis. Conclusions Patients with LSS have an increased epidural pressure at the level of the stenosis and altered pressure wave characteristics below. We argue that the absence of sedimentation of lumbar nerve roots to the dorsal part of the dural sac in supine position may be due to tethering of affected nerve roots at the level of the stenosis.

Delivery of health care at the end of life in cancer patients of four swiss cantons a retrospective database study (SAKK 89/09)

Background The use of cancer related therapy in cancer patients at the end-of-life has increased over time in many countries. Given a lack of published Swiss data, the objective of this study was to describe delivery of health care during the last month before death of cancer patients. Methods Claims data were used to assess health care utilization of cancer patients (identified by cancer registry data of four participating cantons), deceased between 2006-2008. Primary endpoints were hospitalization rate and delivery of cancer related therapies during the last 30 days before death. Multivariate logistic regression assessed the explanatory value of patient and geographic characteristics. Results 3809 identified cancer patients were included. Hospitalization rate (mean 68.5%, 95%CI 67.0-69.9) and percentage of patients receiving anti-cancer drug therapies (ACDT, mean 14.5%, 95%CI 13.4-15.6) and radiotherapy (mean 7.7%, 95%CI 6.7-8.4) decreased with age. Canton of residence and insurance type status most significantly influenced the odds for hospitalization or receiving ACDT. Conclusions The intensity of cancer specific care showed substantial variation by age, cancer type, place of residence and insurance type status. This may be partially driven by cultural differences within Switzerland and the cantonal organization of the Swiss health care system.

Cancer-related therapies at the end of life in hospitalized cancer patients from four Swiss cantons: SAKK 89/09.

The use of cancer-related therapies in cancer patients hospitalized at the end of life has increased in many countries over time. Given the scarcity of published Swiss data, the objective of this study was to evaluate the influence of hospital type and other factors on the delivery of health care during the last month before death. Claims data were used to assess health care utilization of cancer patients (identified by cancer registry data of four participating Swiss cantons) who deceased between 2006 and 2008. Primary endpoints were delivery of cancer-related therapies during the last 30 days before death. Multivariate logistic regression assessed the explanatory value of hospital type, patient and geographic characteristics. Of 3,809 identified cancer patients in the claims database, 2,086 patients dying from cancer were hospitalized during the last 30 days before death, generating 2,262 inpatient episodes. Anticancer drug therapy was given in 22.2% and radiotherapy in 11.7% of episodes. Besides age and cancer type, the canton of residence and hospital type showed independent, statistically significant associations with intensity of care, which was highest in university hospitals. These results should initiate a discussion among oncologists in Switzerland and may question the compliance with standard of care guidelines for terminal cancer patients.

Simulating Energy Transfer and Upconversion in β-NaYF 4 : Yb 3+ , Tm 3+

The design of upconversion phosphors with higher quantum yield requires a deeper understanding of the detailed energy transfer and upconversion processes between active ions inside the material. Rate equations can model those processes by describing the populations of the energy levels of the ions as a function of time. However, this model presents some drawbacks: energy migration is assumed to be infinitely fast, it does not determine the detailed interaction mechanism (multipolar or exchange), and it only provides the macroscopic averaged parameters of interaction. Hence, a rate equation model with the same parameters cannot correctly predict the time evolution of upconverted emission and power dependence under a wide range of concentrations of active ions. We present a model that combines information about the host material lattice, the concentration of active ions, and a microscopic rate equation system. The extent of energy migration is correctly taken into account because the energy transfer processes are described on the level of the individual ions. This model predicts the decay curves, concentration, and excitation power dependences of the emission. This detailed information can be used to predict the optimal concentration that results in the maximum upconverted emission.
