In patients who underwent a second operation, the incidence and severity of adhesions were significantly AZ 628 lower for the treated area compared with the untreated area.\n\nConclusions: HA/CMC membrane was effective in reducing postoperative abdominal adhesions. The incidence of adhesion-related postoperative ileus after colorectal cancer surgery was unchanged. The results of qualitative analysis imply that further improvement of application may allow HA/CMC membrane to be more effective in reducing postoperative ileus.”
“The AAPM Low Energy Brachytherapy Source Calibration Working Group was formed to investigate and recommend quality control and quality assurance

procedures for brachytherapy sources prior to clinical use. Compiling and clarifying recommendations established by previous AAPM Task Groups 40, 56, and 64 were among the working group’s charges, which also included the role of third-party handlers to perform loading and assay of sources. This document presents the findings of the working group on the responsibilities of the institutional medical physicist and a clarification of the existing AAPM recommendations in the assay of brachytherapy sources. Responsibility for the performance and attestation of source assays rests with the institutional medical

physicist, who must use calibration equipment appropriate for each source type used at the institution. Such equipment and calibration procedures shall ensure secondary traceability BIBF 1120 in vitro to a national standard. For each multi-source implant, 10% of the sources AS1842856 mouse or ten sources, whichever is greater, are to be

assayed. Procedures for presterilized source packaging are outlined. The mean source strength of the assayed sources must agree with the manufacturer’s stated strength to within 3%, or action must be taken to resolve the difference. Third party assays do not absolve the institutional physicist from the responsibility to perform the institutional measurement and attest to the strength of the implanted sources. The AAPM leaves it to the discretion of the institutional medical physicist whether the manufacturer’s or institutional physicist’s measured value should be used in performing dosimetry calculations.

“Study Objective: To evaluate the sensitivity and specificity of various predictors of hypotension during onset of spinal anesthesia in elderly patients.\n\nDesign: Prospective study.\n\nSetting: 32 ASA physical status I, II, and I I I patients, aged 60 years. scheduled for elective lower limb surgery with spinal anesthesia.\n\nInterventions: Patients received spinal anesthesia with 10-17.5 mg of bupivacaine. No prophylactic ephedrine or fluid preloading was used.\n\nMeasurements: A 5-minute baseline was recorded and during onset of spinal anesthesia.
