Anticoagulated Patient

We present a case of a 58-year-old patient with a low energy trauma developing compartment syndrome. He required multiple surgeries, including fasciotomy and removal of a large haematoma. He continued to bleed with a vacuum-assisted closure dressing in situ, requiring prothrombin complex Concentrate and blood transfusion. This case highlights the need for an increased awareness of possible development of compartment syndrome following low impact trauma in a patient who is anticoagulated and raises the question of a possible period of observation for those who may be at risk.

Ion Beam Sputtering

ABSTRACTIon-beam sputtering (IBS) has been studied as a means for scalable, mask-less nanopatterning of surfaces. Patterning at the nanoscale has been achieved for numerous types of materials including: semiconductors, metals and insulators. Although much work has been focused on tailoring nanopatterning by systematic ion-beam parameter manipulation, limited work has addressed elucidating on the underlying mechanisms for self-organization of multi-component surfaces. In particular there has been little attention to correlate the surface chemistry variation during ion irradiation with the evolution of surface morphology and nanoscale self-organization. Moreover the role of surface impurities on patterning is not well known and characterization during the time-scale of modification remains challenging. This work summarizes an in-situ approach to characterize the evolution of surface chemistry during irradiation and its correlation to surface nanopatterning for a variety of multi-components surfaces. The work highlights the importance and role of surface impurities in nanopatterning of a surface during low-energy ion irradiation. In particular, it shows the importance of irradiation-driven mechanisms in GaSb(100) nanopatterning by low-energy ions and how the study of these systems can be impacted by oxide formation.

AbstractWe demonstrate a vacuum lithography process which uses a finely focused Ga ion beam to write the pattern which is then transferred to the InP pattern by low energy dry etching. Surface steps on the order of 1000-2000A in height, and lateral resolution limited only by size of the ion beam, can be efficiently prepared using moderate Ga ion fluences. The surfaces prepared by this process are damage free and suitable for epitaxial overgrowth. GaInAs/InP heterostructures grown on in-situ patterned substrates show excellent morphology and high luminescence efficiency.

Introduction. Screening and identification of anti-erythrocyte alloimmune antibodies in recipients is an important and necessary step in their testing before blood transfusion.Aim. To formulate algorithms that could facilitate the process of pre-transfusion immunohematological testing.General findings. Such a testing allows the development of post-transfusion reactions and complications to be avoided. The presence of alloantibodies of various specificities and autoantibodies in the test blood may complicate pre-transfusion testing and require the use of additional methods (adsorption, elution, etc.). The author has proposed an effective system of algorithms for conducting immunohematological studies, which can be used to identify patients at risk of developing immune post-transfusion complications and ensure an individual selection of compatible donor blood-transfusion products.
