The treatment of intramedullary infections after nailing usually includes removal of the nail, debridement, and, in some cases, insertion of antibiotic-impregnated cement beads. We use this self-made antibiotic cement rod to treat intramedullary infections. Compared with the beads, it provides some limited mechanical support and can be preserved in the canal for a long time. We reviewed 19 infected patients who underwent removal of the nails, excision of sinus tracks, debridement of the canal and insertion of the rods. No recurrent infection occurred in 18 cases and 11 cases achieved bone healing, 6 cases achieved partial union. One patient had nonunion and one patient underwent amputation because of severe primary trauma and long-term infection. The rod was removed between 35 and 123 days after implantation. We conclude that the antibiotic cement rods could be a relatively effective, simple and inexpensive method of treating intramedullary infections after nailing.
Generally, the facial nerve was successfully preserved in 10 of 12 cases (83.30%), and nerve grafting was required in 2 cases. Seven of 10 patients (70%) with nerve intact recovered to grade I or grade II, while the 2 cases with nerve grafting recovered to grade III or grade IV. Among the smaller size group, the facial nerves of all patients (100%) were intact. In contrast, only one of three patients (33.3%) in the larger size group maintained nerve integrity after surgery.
Background: To investigate the protective effect of Ixeris Sonchifolia (Bae.) Hance (ISH) extract on herpes simplex virus keratitis (HSK) in mice. Methods: A mouse model of HSK was established by inoculating 60 mice (60 right eyes) with herpes simplex virus type 1 (HSV-1) by corneal scratch. The other 15 mice as blank control only received corneal scratch but without HSV-1. From the 2nd day after the successful modeling, the experimental group was fed with ISH total flavonoids (50, 100 and 200 mg/kg) orally, twice a day for 14 days. The model group and control group were given the same amount of normal saline. The pathological changes of cornea were observed once a day by slit lamp microscopy combined with fluorescein staining. The corneal histopathological examination, the survival status and the serum levels of interleukin-2 (IL-2), IL-4 and interferon-gama (INF-γ) were performed at the end of the experiment. Results: The result showed that ISH could significantly improve the corneal lesion degree, increase mice survival rate, and markedly increase the levels of IL-2 and INF-γ, reduce the levels of IL-4 in serum of mice. Conclusions: ISH could increase the anti-virus ability, promote the healing of corneal inflammation and alleviate the pathological damage of cornea, which suggested that ISH has a potential and valuable therapeutic effect on the HSK.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
