The most frequently ingested foreign bodies in children are coins, toys, magnets and batter-ies. Most foreign body ingestions in adults occur while eating, leading to either bone or meat bolus impaction. Flexible endoscopy is the therapeutic method of choice for relieving food impaction and removing true foreign bodies with a success rate of over 95% and with mini-mal complications. This review describes a comprehen-sive approach towards patients presenting with foreign body ingestion. Recommendations are based on a review of the literature and extensive personal experi-ence.展开更多

The search terms were ＂impaction bone grafting＂, ＂particle size＂, ＂mechanical property＂and ＂biological behavior＂.Study selection Articles relevant to the choices of allografts and their results for bone defect reconstruction on the acetabular side were selected.Results Different choices of allografts, including the particle size, process of irradiation or fat reduction, composition and particle grade, are made to improve the survival rate of a prosthesis in acetabular revision surgery. This review,which compares both mechanical and biological factors, summarizes the experimental and clinical results for different techniques.Conclusions Fresh frozen cancellous allografts with particle sizes ranging from 7 to 10 mm are a favorable choice for reconstruction of bone defects of American Academy of Orthopedic Surgeons （AAOS） types Ⅱ （cavitary defect） and Ⅲ（combined cavitary and segmental defect） on the acetabular side. A fat-reducing procedure with saline or solvent/detergent is controversial. Adding autologous marrow into irradiated allografts, which provides reliable mechanical stability and biological safety, may be a substitute for fresh frozen allografts. Cortical bone can be a supplementary material in cases of insufficiency of cancellous allografts. Cartilage should be excluded from the graft material. Further research is required to demonstrate the best particle grade, and randomized controlled trials in clinical practice are required to obtain more information about the selection of allografts.展开更多

With the progression of the patient's condition, gastrointestinal dysfunction is frequently complicated. At the same time, the accumulation of feces in the body (colonic impaction) can also increase the burden on the patient’s heart, triggering or exacerbating the occurrence or progression of heart failure. Purpose: this article focuses on the correlation between colonic impaction and heart failure, using the nursing experience of a case of acute left heart failure complicated by colonic impaction as an example, in order to provide clinical evidence for the care of patients with colonic impaction combined with heart failure in the future. Method: By using innovative thinking, the stomach tube is used to replace the enema tube, which is inserted through the anus to reach the end of the colon. By combining acupressure at points such as Zhongwan, Tianzhu, and Guanyuan, it helps promote the elimination of fecal impaction. Conclusion: This case reflects the innovative thinking and adaptability of nurses, providing a new clinical approach for the aggravation of the condition of long-term heart failure patients due to constipation issues. Further research in clinical practice is warranted.展开更多
