A system for frozen RBC storage with 3-week, postthaw, liquid storage has been validated. With commercially available components and automated processing, it is capable of supporting civilian rare blood and emergency and international military combat and peacekeeping support use patterns.

Background Pneumothorax as a consequence of pulmonary barotrauma during explosive decompression military crew training in a hypobaric chamber is an extremely rare and sparsely diagnosed complication. Extensive bilateral tissue damage is even more unexpected. Case presentation A 26-year-old active duty Air Force pilot was performing an explosive decompression simulation from 8000 ft. (2438.4 m) to 25,000 ft. (7620 m) in a 1.5 s interval. The training was interrupted due to the pilot’s apparent health complications. After transfer to the emergency department, a CT scan showed bilateral lung barotrauma with emphysema. Conclusions The case report shows extensive emphysema and pneumothorax after a rapid decompression done for training purposes. It is a possible but rare complication. The cause remains unclear, with suspicion of a predisposed lung disease.

Background: Hyperbaric oxygen (HBO2) therapy canhave a positive effect on wound healing, angiogenesis and blood flow. No prior study has described the effects of HBO2 therapy and gene expression of this process. The goal of our research was to show the effects of HBO2 and its impact at the molecular level on angiogenesis, proliferation, differentiation, oxidative stress, inflammation, and extracellular matrix formation. Live animal subjects were used for simulating the process of wound healing under standard conditions and under the influence of HBO2. Methods: Two experimental groups were created using injured rabbits (N=24), one group (N=12) treated with hyperbaric therapy twice a day and one (N=12) with standard wound care management. Wounds were surgical, uninfected, and in healthy animal test subjects. We compared the whole genomic analysis of the transcriptome with the use of microarray technology at three intervals during treatment. Results: The induction of the wounds in rabbit skin increased expression of hundreds of genes in both treatment groups. The numbers of elevated and decreased genes gradually reduced as the wound healed. Gene expression analysis showed elevated expression of several genes associated with inflammation in both groups of injured animals. Genes connected to the process of angiogenesis, proliferation, differentiation, oxidative stress and extracellular matrix formation were without statistically significant changes. Conclusion: The evidence did not support that HBO2 had any significant effect on gene expression during wound healing. Additionally, there was no evidence to support that there were changes in gene expression in either treatment group.

Between April 24 and September 18, 2003, a total of 7,099 outpatient treatments were performed. Between June 3 and September 18, 2003, a total of 124 patients were surgically treated and 209 patients were hospitalized; the hospital recorded 1,239 bed-days, 137 of them in the intensive care unit. A total of 924 X-ray and ultrasound examinations were performed, as well as 10,014 laboratory tests. Local inhabitants accounted for 90.5% of the patients. In their practice, the doctors encountered a very wide spectrum of surgical and nonsurgical diagnoses. Part of the work was to support humanitarian activities, with supplies of humanitarian material, selection of children for specialized cardiosurgical treatment in the Czech Republic, and blood donations. Work in that unstable region was significantly complicated by the extreme climate and the high security risk.

HighlightsChronic organized hematoma is rare surgery complication, it is uncommon after laparoscopic hernia repair especially.Two patients were re-operated on with groin tumorous mass in longer intervals after transabdominal preperitoneal inguinal hernia repair from the anterior access.Tumorous bulk outside of postoperative scars and outside original operating space was made up of old organized hematoma.Only removal of tumour could exclude neoplasm and ends patient’s mechanical restrictions.
