227. Der gestielte Peronaeus-Insellappen als Alternative zum freien Gewebetransfer am distalen Unterschenkel und Fuß

Zusammenfassung Der distal gestielte Peronaeus-Insellappen, erstmals 1984 von Yoshimura publiziert, ist ein fasciocutaner Lappen, der über einen Hautast der A. peronea ernährt wird. Die A. peronea weist distal, ca 5 cm oberhalb des Sprunggelenkes, einen Ramus perforans zur A. tibialis anterior auf und über einen Ramus communicans besteht eine Verbindung zur A. tibialis posterior. Unterbindet man die A. peronea proximal der Abgangsstele der Hautarterie, so kommt es über die distalen Anastomosen zur retrograden Durchblutung. Der distal gestielte Peronaeuslappen besitzt einen großen Schwenkbereich bis hin zum Fußrücken. Die Durchgängigkeit der drei Unterschenkelarterien ist die Voraussetzung für die Durchführbarkeit. Die Indikation ergibt sich bei oberflächlichen Knochen- und Hautdefekten im distalen Unterschenkeldrittel, der Malleolengabel, der Ferse und des Fußrückens.     

BKV in Simultaneous Pancreas-Kidney Transplant Recipients: A Leading Cause of Renal Graft Loss in First 2 Years Post-Transplant

With the introduction of more potent immunosuppressive agents, rejection has decreased in simultaneous pancreas/kidney transplant (SPK) recipients. However, as a consequence, opportunistic infections have increased. The purpose of this report is to outline the course of SPK patients who developed polyomavirus-associated nephropathy (PVAN). A retrospective review of 146 consecutive SPK recipients from January 1, 1996 to December 31, 2002 was performed. Immunosuppression, rejection and development of PVAN were reviewed. Nine patients were identified. All received induction with either OKT3 or thymoglobulin. Immunosuppression included tacrolimus/cyclosporine, MMF/azathioprine and sirolimus/prednisone. Two patients were treated for kidney rejection prior to the diagnosis of PVAN. Time to diagnosis was an average of 359.3 days post-transplantation. Immunosuppression was decreased but five ultimately lost function. However, none developed pancreatic abnormalities as demonstrated by normal glucose and amylase. Two underwent renal retransplantation after PVAN diagnosis and both have normal kidney function. PVAN was the leading cause of renal loss in SPK patients in the first 2 years after transplantation and is a serious concern for SPK recipients. The pancreas, however, is spared from evidence of infection, and no pancreatic rejection occurred when immunosuppression was decreased.     

Characteristic modifications of the breathing pattern of mice to evaluate the effects of airborne chemicals on the respiratory tract

A system was developed for exposure of unanesthetized mice to airborne chemicals and for continuous measurement of their breathing pattern prior to, during and following exposure. By measuring inspiratory and expiratory airflows (VI and VE), and integration with time to yield tidal volume (VT), we obtained characteristic modifications to the normal breathing pattern. These permitted recognition that a specific portion of the respiratory tract was affected by the selected airborne chemicals. Following recognition, we also quantitated the degree of effect using one specific measurement in each case. An effect on the upper respiratory tract, induced by the sensory irritant, 2-chlorobenzylchloride, was quantitated by measuring a decrease in respiratory frequency. An effect on the conducting airways, induced by the airway constrictor, carbamylcholine, was quantitated by a decrease in VE at the mid-point of VT. An effect at the alveolar level, induced either by the vagal nerve ending stimulant, propranolol, or by the pulmonary irritant, machining fluid G, was quantitated by an increase in the length of a pause induced at the end of expiration. The system is easy to construct and operate and can be used to rapidly evaluate the effects of airborne chemicals on the respiratory tract.     

Slit drainage--progress in drainage treatment after herniotomy]

In a prospective randomized study was conducted on 80 patients undergoing elective hernia repair to assess whether a new slit-suction drainage is less painful than a Redon-suction drainage. Main endpoint of the study was the traction power in order to remove the drain. Other endpoints were pain at the time of removal of the drain and the effectiveness to draw off secretion. To remove redon drain the average traction power was 226 pond and to remove slit drain the average traction power was only 25 pond. The difference was significant (p less than 0.01). At the time of removal patients with slit drain rarely complained about pain (p less than 0.01). On contrary, patients with Redon drain always complained about pain. Clotting were seldom shown in slit drains and were frequently shown in redon drains. Both slit drains and redon drains were effective to drain secretion. As the new slit drain was more comfortable for patients following hernia repair slit drain should always be used as subcutaneous suction drainage.     

Identifying potential indicators of the quality of end-of-life cancer care from administrative data.

PURPOSE: To explore potential indicators of the quality of end-of-life services for cancer patients that could be monitored using existing administrative data. METHODS: Quality indicators were identified and assessed by literature review for proposed indicators, focus groups with cancer patients and family members to assess candidate indicators and generate new ideas, and an expert panel ranking the meaningfulness and importance of each potential indicator using a modified Delphi approach. RESULTS: There were three major concepts of poor quality of end-of-life cancer care that could be examined using currently-available administrative data (such as Medicare claims): institution of new anticancer therapies or continuation of ongoing treatments very near death; a high number of emergency room visits, inpatient hospital admissions, or intensive care unit days near the end of life; and a high proportion of patients never enrolled in hospice, only admitted in the last few days of life, or dying in an acute-care setting. Concepts such as access to psychosocial and other multidisciplinary services and pain and symptom control are important and may eventually be feasible, but they cannot currently be applied in most data systems. Indicators based on limiting the use of treatments with low probability of benefit or indicators based on economic efficiency were not acceptable to patients, family members, or physicians. CONCLUSION: Several promising claims-based quality indicators were identified that, if found to be valid and reliable within data systems, could be useful in identifying health-care systems in need of improving end-of-life services.
