Background: We analyzed association between viewing two-dimensional computed tomography (2D CT) images in addition to radiographs with radial head treatment recommendations after accounting for patient and surgeon factors in a survey-based experiment. Methods: One hundred and fifty-four surgeons reviewed 15 patient scenarios with terrible triad fracture dislocations of the elbow. Surgeons were randomized to view either radiographs only or radiographs and 2D CT images. The scenarios randomized patient age, hand dominance, and occupation. For each scenario, surgeons were asked if they would recommend fixation or arthroplasty of the radial head. Multi-level logistic regression analysis identified variables associated with radial head treatment recommendations. Results: Reviewing 2D CT images in addition to radiographs had no statistical association with treatment recommendations. A higher likelihood of recommending prosthetic arthroplasty was associated with older patient age, patient occupation not requiring manual labor, surgeon practice location in the United States, practicing for five years or less, and the subspecialties “trauma” and “shoulder and elbow.” Conclusions: The results of this study suggest that in terrible triad injuries, the imaging appearance of radial head fractures has no measurable influence on treatment recommendations. Personal surgeon factors and patient demographic characteristics may have a larger role in surgical decision making.

One of the salient nuclear fuel performance parameters for new fuel types under development is changes in fuel thickness. To test the new commercially fabricated U-10Mo monolithic plate-type fuel, an irradiation experiment was designed that consisted of multiple mini-plate capsules distributed within the Advanced Test Reactor (ATR) core, the mini-plate 1 (MP-1) experiment. Each capsule contains eight mini-plates that were either fueled or "dummy" plates. Fuel thickness changes within a fuel assembly can be characterized by measuring the gaps between the plates ultrasonically. The channel gap probe (CGP) system is designed to measure the gaps between the plates and will provide information that supports qualification of U-10Mo monolithic fuel. This study will discuss the design and the results from the use of a custom-designed CGP system for characterizing the gaps between mini-plates within the MP-1 capsules. To ensure accurate and repeatable data, acceptance and calibration procedures have been developed. Unfortunately, there is no "gold" standard measurement to compare to CGP measurements. An effort was made to use plate thickness obtained from post-irradiation measurements to derive channel gap estimates for comparison with the CGP characterization.

Purpose: Historically, it was thought that hemorrhagic complications were increased with transrectal ultrasound-guided prostate biopsies (TRUS biopsy) of patients receiving anticoagulation/antiplatelet therapy. However, the current literature supports the continuation of anticoagulation/antiplatelet therapy without additional morbidity. We assessed our experience regarding the continuation of anticoagulation/antiplatelet therapy during TRUS biopsy. Materials and Methods: A total of 91 and 98 patients were included in the anticoagulation/antiplatelet (group I) and control (group II) groups, respectively. Group I subgroups consisted of patients on monotherapy or dual therapy of aspirin, warfarin, clopidogrel, or low molecular weight heparin. The TRUS biopsy technique was standardized to 12 cores from the peripheral zones. Patients completed a questionnaire over the 7 days following TRUS biopsy. The questionnaire was designed to assess the presence of hematuria, rectal bleeding, and hematospermia. Development of rectal pain, fever, and emergency hospital admissions following TRUS biopsy were also recorded. Results: The patients’ mean age was 65 years (range, 52 to 74 years) and 63.5 years (range, 54 to 74 years) in groups I and II, respectively. The overall incidence of hematuria was 46% in group I compared with 63% in group II (p=0.018). The incidence of hematospermia was 6% and 10% in groups I and II, respectively. The incidence of rectal bleeding was similar in group I (40%) and group II (39%). Statistical analysis was conducted by using Fisher exact test. Conclusions: There were fewer hematuria episodes in anticoagulation/antiplatelet patients. This study suggests that it is not necessary to discontinue anticoagulation/antiplatelet treatment before TRUS biopsy.
