Evaluation of a fever of unknown origin (FUO) is complex. Recently, PET scanning has been approved for screening in FUO evaluation. We treated three cases of FUO associated with increased FDG uptake in the bone marrow of the femur and tibia on the fusion PET/CT; all three had the same pattern of uptake. Bone marrow biopsies revealed mature lymphocyte and histiocyte infiltration and myxoid changes in one case, and cortical bone involvement in another case. The cases were all young females who had fever with neutropenia and relative lymphocytosis that lasted for several weeks and then remitted spontaneously. Even though the results of the studies were not diagnostic, the unique uptake pattern on PET/CT and the histology might be related to the cause of the illness and should be studied further to assess the association with classic FUO.

PURPOSE: We planned to determine the diagnostic capability of focused assessment with sonography for trauma (FAST) in cases of blunt abdominal injury (BAI). METHODS: A retrospective analysis of FAST sheets was performed from April 2002 to December 2004. During the study period, 135 BAI patients were evaluated with FAST at the Emergency Department of Bundang CHA Hospital. Of this group, twenty-eight patients were excluded, leaving 107 patients for analysis. Abdomen CT (computerized tomography) or exploratory laparotomy confirmed the presence of hemoperitoneum. At the secondary survey, patients underwent a three-view FAST examination (LogicQ; General Electric, Waukesha, USA) by an emergency physician, followed within 2 hours by an abdomen CT or exploratory laparotomy. The FAST examination was considered positive if it demonstrated evidence of free intra-abdominal fluid. RESULTS: There were 45 true-positive FAST examination, 57 true-negatives, 1 false-positive, and 4 false negatives (sensitivity 91.8%, specificity 98.3%, positive predictive value 97.8%, negative predictive value 93.4%). The area under the ROC curve was 0.951 for the FAST examination. CONCLUSION: FAST is a highly reliable method for screening patients suspected of having BAI for the presence or absence of hemoperitoneum.

STUDY DESIGN: Case report OBJECTIVES: To report a case of sacral stress fracture that developed after lumbosacral fusion. SUMMARY OF LITERATURE REVIEW: Sacral stress fractures rarely develop after lumbosacral fusion, and osteoporosis, female sex, being over 60 years old, and long segment fusion are known risk factors. MATERIALS AND METHODS: A 66-year-old woman with spondylolisthesis at L5 on S1 underwent posterior lumbar interbody fusion and posterior instrumentation. A sacral stress fracture was found 4 weeks after the first operation, and we performed posterior reduction and posterior instrumentation with S2 alar screws. RESULTS: The patient was free from symptoms and no further displacement was found at 3 months after the last operation. CONCLUSIONS: Sacral stress fracture after lumbosacral fusion can be treated with posterior reduction and posterior instrumentation with S2 alar screws.

Purpose: Surgery to create a stoma for decompression might be required for unresectable stage IV cancer patients with complete colonic obstruction. The aim of this study was to compare the results of blowhole colostomy with those of loop ostomy. Methods: Palliative ileostomy or colostomy procedures performed at a single center between January 2011 and October 2020, were analyzed retrospectively. Fifty-nine patients were identified during this period. The demographic characteristics and outcomes between the blowhole colostomy group (n=24) and the loop ostomy group (n=35) were compared. Results: The median operative time tended to be shorter in the blowhole colostomy group (52.5 minutes; interquartile range [IQR], 43–65) than in the loop ostomy group (60 minutes; IQR, 40–107), but the difference did not reach statistical significance (P=0.162). The median length of hospital stay was significantly shorter with blowhole colostomy (blowhole, 13 days [IQR, 9–23]; loop, 21 days [IQR, 14–37]; P=0.013). Mean cecum diameter was significantly larger in the blowhole group than in the loop group (8.83±1.91 cm vs. 6.78±2.36 cm, P=0.001), and the emergency operation rate was higher in the blowhole group than in the loop group (22 of 24 [91.7%] vs. 23 of 35 [65.7%], P=0.021). Conclusion In surgical emergencies, diverting a blowhole colostomy can be safe and effective for palliative management of colonic obstruction in patients with end-stage cancer and might reduce the operative time in emergent situations.
