Orthopaedic surgeons should be aware, and family members of those patients should be informed, that the likelihood of an open reduction in these types of injuries is extremely high. Open reduction is needed not only to achieve an anatomic reduction of the fracture but to make sure that the ulnar nerve is not entrapped between the proximal and distal fragment.BACKGROUND The preservation of harvested organs plays an essential role in transplantation. Cold hypothermia is frequently applied but may lead to graft compromise resulting from reperfusion and rewarming injury. This study investigates the effect of deep hypothermia and posterior rewarming on leukocyte-endothelial interactions and junctional adhesion molecules. MATERIAL AND METHODS We established an in vitro model to investigate the transendothelial migration of leukocytes (TEM) during deep hypothermia (4°C) as well as during the post-hypothermic rewarming process. Additionally, leukocyte-endothelial interactions were analyzed by quantifying surface expression of the junctional adhesion molecules A (JAMA-A and JAM-B). RESULTS While deep hypothermia at 4°C was associated with reduced leukocyte infiltration, rewarming after hypothermic preservation resulted in a significant increase in TEM. This process is mainly triggered by activation of endothelial cells. Post-hypothermic rewarming caused a significant downregulation of JAM-A, whereas JAM-B was not altered through temperature modulation. CONCLUSIONS Hypothermia exerts a protective effect consisting of reduced leukocyte-endothelial interaction. Rewarming after hypothermic preservation, however, causes considerable upregulation of leukocyte infiltration. Downregulation of JAM-A may play a role in modulating TEM during hypothermia and rewarming. We conclude that the rewarming process is an essential but underestimated aspect during transplantation.BACKGROUND Current histological methods cannot accurately determine the survival rate of human pancreatic islets following portal vein infusion. This is due, in part, to the low number of infused islets relative to the whole liver. In this study we assessed the ability of confocal laser scanning microscopy (CLSM) to track human islets posttransplantation. METHODS Immune-deficient mice were transplanted with human islets. Following engraftment, animals were euthanized, livers procured, and human islet β cells immunofluorescently labelled with an insulin-specific antibody and evaluated by CLSM. A calibration curve comparing the area of insulin + hepatic islet β cells to the number human islets collected was developed. Levels of human C-peptide were measured in transplant recipients to determine islet function. RESULTS The short-term survival rate of islet transplants was defined as y =0.0422x + 2.7008 where x is human islet number and y is liver islet β cell area. Employing CLSM, human islets were detected in immunofluorescent labelled murine liver tissue sections posttransplantation. The β cell-relative area of human islets in 500 IEQ specimens was 20.21 ± 1.16 mm and in 1000 IEQ specimens 39.4 ± 2.23 mm posttransplantation. Human islet posttransplant survival rates were 82.9 ± 5.50 % (500 IEQ group) and 86.9 ± 5.28 % (1000 IEQ group). CONCLUSIONS These data indicate that CLSM can be employed to quantify and characterize pancreatic human islets after transplantation to murine livers.BACKGROUND Invasive pulmonary aspergillosis (IPA) is a significant cause of morbidity and mortality in lung transplant recipients (LTRs). It is unclear how a targeted prophylaxis/ preemptive antifungal therapy strategy impacts the incidence of IPA beyond the first-year posttransplant. METHODS This is a retrospective cohort of LTRs from January 2010 to December 2014. We included all LTRs who survived beyond the first year, and followed them until death or 4 years postoperatively. Incidence of probable/proven IPA and Aspergillus colonization were assessed as per ISHLT criteria. Patients with risk factors, positive Aspergillus cultures, and/or galactomannan (GM) received targeted prophylaxis/ preemptive therapy within the first-year posttransplant. RESULTS During the study period, 350 consecutive LTRs underwent 1078 bronchoscopies. Positive bronchoalveolar lavage for GM and/or Aspergillus cultures was reported for 15% (52/350) of LTRs between 2 and 4 years after transplantation. Among them, the median time to positive Aspergillus culture or GM positivity was 703 days (IQR 529-754). The incidence rate of IPA and Aspergillus colonization was 30/1000 patient-years, and 63/1000 patient-years respectively. this website The mortality rate was significantly higher in patients with IPA than without IPA (107/1000 patients-years vs. 18/1000 patient-years; p less then 0.0001). Rate of first year colonization and IPA was 33% and 9% respectively. Among the 201 patients who had a negative bronchoscopy during the 1 year posttransplant, only 6 (3%) developed IPA during the follow-up. CONCLUSION A targeted prophylaxis/ preemptive therapy strategy within the first-year posttransplant resulted in 4% incidence of IPA at 4-years after transplantation. However, IPA was associated with higher mortality.RATIONALE Foreign body (FB) ingestion is a relatively common clinical situation in the emergency department. However, multiple sharply pointed foreign bodies located in different organs are rare conditions and no definite treatment guidelines has been established. PATIENT CONCERNS A 31-year-old amateur magician visited the outpatient clinic with a chief complaint of epigastric discomfort. He might have accidentally swallowed some needles while practicing a magic trick 2 days before. DIAGNOSIS Imaging tests revealed 1 needle was stuck in the left liver lobe through the stomach wall, 1 was in the third portion of the duodenum, 3 were in the ascending colon, and 2 were in the transverse colon. INTERVENTIONS A needle in the duodenum and 5 in the colon were removed by endoscopy. The needle stuck in the liver from the stomach was not visible inside the stomach and was successfully removed by laparoscopy a few days later. OUTCOMES The patient was able to tolerate an oral diet and was discharged on postoperative day 4 without any complications.
