[Geriatric trauma centers - requirements catalog. An initiative to promote and guarantee the quality of care of elderly trauma patients receiving inpatient care]. / Alterstraumatologisches Zentrum - Anforderungskatalog. Eine Initiative zur Förderung und Sicherung der Qualität der Versorgung alterstraumatologischer Patienten in Deutschland im Bereich der stationären Versorgung.

For the care of the elderly, specific geriatric care facilities in hospitals and specialized rehabilitation centers have been established in the last 20 years throughout Germany. In addition, trauma surgery departments in hospitals and clinics also provide comprehensive care for trauma patients. The present requirements catalog was developed with the aim to ensure the standardization and quality assurance of these care facilities. Thus, the structural basics and, in particular, the structured cooperation between geriatrics and trauma surgery are described and defined in terms of structure, process, and outcome quality. The Bundesverband Geriatrie, the Deutsche Gesellschaft für Geriatrie, and the Deutsche Gesellschaft für Gerontologie und Geriatrie offer documentation for external and internal use and evaluation of the structures and processes for certification of geriatric trauma centers. Prerequisite for certification is to meet the technical requirements defined in the requirements catalogue or documents derived from it, and proof of a quality management system according to ISO 9001.

[Perioperative nutritional therapy]. / Perioperative Ernährungstherapie.

BACKGROUND: There is no difference in medical and nutritional therapy between elderly and young surgical patients. However, based on the high prevalence of malnutrition or a risk for malnutrition and the associated risk for complications, elderly surgical patients should receive special attention. AIM: This article addresses the options in perioperative nutritional therapy and gives an overview on current guidelines and study results. MATERIALS AND METHODS: The article includes a literature review of current national and international guidelines in the field of surgery and geriatrics. Cochrane reviews, systematic reviews, meta-analyses, and significant single studies are also included. RESULTS: Contrary to former approaches, national and international organizations recommend to keep the duration of pre- and postoperative fasting as short as possible. The benefits of nutritional therapy in stabilization and improvement of the nutritional status of surgical patients has already been shown in several patient groups like patients undergoing major abdominal surgeries. For other patients groups, like patients with sepsis, further studies are needed to evaluate the benefit of a perioperative nutritional intervention.

Computer applications to radioactive-seed: brain-tumor implants.

Malignant brain tumors, in general, and anaplastic astrocytoma and glioblastoma multiforme in particular, have been highly refractory to conventional treatments including surgery, chemotherapy and external-beam irradiation. Although better local control can be achieved with high-dose, external beam irradiation, necrosis of normal brain tissue reduces the quality of life and survival. In order to localize the radiation dose given to brain tumors, the temporary implantation of 125I and 192Ir seeds is undergoing clinical trials at several medical centers. Computers play a key role in this treatment modality: in addition to being essential for image reconstruction of CT scans, a computer is used to reconstruct a tumor volume from outlined regions on individual cuts; a programable calculator is used in conjunction with a stereotaxic head holder to obtain the coordinates of the radioactive seeds; a radiation-therapy, treatment-planning computer is used to optimize the radioactive-seed positions and strengths, and to generate the corresponding dose distribution.

Selenium-75: a potential source for use in high-activity brachytherapy irradiators.

A study was made to find a high-specific-activity radioisotope having a longer half-life and lower gamma-ray energies than 192Ir in order to replace 192Ir in high-activity afterloading brachytherapy devices. Based upon a number of considerations, 75Se was selected. The present paper describes the physical properties of 75Se, its method of production, and the properties of an encapsulated source that was fabricated to prove the accuracy of our initial calculations.
