Successful surgery for secondary aortoduodenal fistula based on 18F-fluorodeoxyglucose positron emission tomography/computed tomography findings

Secondary aortoduodenal fistula (sADF) is a critical late complication of abdominal aortic repair, requiring complete excision of the infected prosthesis. However, this is a highly invasive procedure for the elderly. We describe a case of sADF repair in a 76-year-old woman. Through 18F (fluorine-18)-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography mapping, focal high FDG uptake at the sADF site, right medial limb, and ligated left lateral limb of the prosthesis was detected. The duodenal and prosthetic grafts were partially resected. The proximal and distal anastomotic segments, with no FDG uptake, were retained. The abdominal aorta was reconstructed using a bovine pericardium roll and femorofemoral bypass. Thus, FDG positron emission tomography/computed tomography mapping of the infection site could help in such cases

Relationship Between Preoperative Psoas Major Muscle Quality and Forgotten Joint Score-12 in Patients After Total Hip Arthroplasty

Background: There are limited reports on the factors affecting the Forgotten Joint Score-12 (FJS-12) in patients after total hip arthroplasty (THA). Therefore, this study aimed to determine whether the quantity and quality of the preoperative psoas muscle are related to the FJS-12 in post-THA patients. Methods: This retrospective cohort study used mailed questionnaires and medical records. Questionnaires containing the FJS-12 were mailed to 752 patients who underwent THA at our hospital between April 2015 and August 2020. The quantity and quality of the psoas major muscle were measured by computed tomography. The association between FJS-12 and the quantity and quality of the psoas major muscle was assessed by logistic regression analysis adjusted for potentially relevant factors. Results: In total, 484 patients were included in the analysis. The FJS-12 score of the analyzed subjects was 75 points. Poor psoas major muscle quality was associated with a poor group of patients scoring <50 on the FJS-12. This association was independent of the adjustment factors. However, the quantity of psoas muscle was not associated. Conclusions: The quality of the psoas major muscle is associated with FJS-12. In the rehabilitation of patients undergoing THA, focusing on the quality of the psoas major muscle may help achieve the ultimate goal

The Effect of Control-released Basic Fibroblast Growth Factor in Wound Healing: Histological Analyses and Clinical Application

Background: Basic fibroblast growth factors (bFGFs) play a crucial role in wound healing by promoting fibroblast proliferation and neovascularization. However, drawback of bFGF is short half-life in free form. Gelatin has a capability of sustaining growth factors, which are gradually released while degradation. The purpose of this study is to see whether bFGF-impregnated gelatin sheet is effective in a murine model and whether it could also be available for patients in a safe manner. Methods: Full-thickness skin defect was created on C57BL/6J mice and covered with bFGF with gelatin sheet (group A), bFGF without gelatin sheet (group B), phosphate buffer saline (PBS) with gelatin sheet (group C), and only PBS (group D). Wound healing was evaluated in terms of percent wound closure, granulation thickness, wound maturity, and vascular density. Clinical trial was conducted for patients who received either acute or chronic ulcers. The sheets were put onto the wounds and covered by hydrocolloid dressing, which was changed weekly. Results: Groups A and B exhibited better wound healing than groups C and D in all aspects. Moreover, group A showed better results than group B at day 7 in terms of wound closure, collagen maturity, and vascularity. Efficacy without any adverse events was found in the clinical series. Conclusions: These findings suggest that control-released bFGF using gelatin sheet is effective for promoting wound healing. Such therapeutic strategy was considered to offer several clinical advantages including rapid healing and reduction of the dressing change with less patient discomfort
