Deep groin infections after prosthetic vascular surgical procedures represent a serious complication of surgical practice. Septicemia and/or erosive hemorrhage can both be consequences. In this situation, removal of the graft appears to be the only option. However, if the infection is detected early (type Szilagyi III), local treatment to eradicate the infection could serve as an alternative. Twenty-four patients with confirmed infection of the soft tissue adjacent to the prosthetic material in the groin were treated locally by implantation of a vacuum sponge system. Duration of this treatment was 2 weeks. All patients showed excellent tissue granulation of the wound area and the microbial stains were negative at the end of therapy. In 21 patients the wound could be primarily closed after explantation of the sponge. Three patients underwent open treatment because of a skin defect. After 12 months, the wounds had healed well in all patients. Histologic evaluation revealed a physiological healing process. Deep soft tissue infections of the groin adjacent to prosthetic vascular material (type Szilagyi III) can be treated effectively and safely with the vacuum sponge system. The treatment is inexpensive, easy to perform, and the initial vascular reconstruction can be preserved.
SUMMARYVacuum-assisted closure involving the implantation of polyvinyl alcohol foam is a technique recently developed for the treatment of patients suffering from either wound infection or chronic wounds. This method has been shown to improve and accelerate wound healing. However, little is known about the cell populations that infiltrate the foam, and their potential role in resolving the infection and promoting granulation tissue formation. Our study demonstrates that wound-implanted foams are mainly infiltrated with granulocytes, but that mononuclear cells, including macrophages and minor populations of T, B and natural killer lymphocytes, are also present. We show that foam-infiltrating T cells, especially CD41 T cells, constitute a phenotypically and functionally heterogeneous population influenced by woundinfecting bacteria. Thus, T lymphocytes could play a role in wound cleansing. In addition, our data indicate that implanted polyvinyl alcohol foams might be suitable microenvironments for manipulating T cell-mediated immune responses in patients.
Background: Xanthogranulomatous cholecystitis is a macrophage-rich inflammatory condition of the gallbladder that occasionally presents with tumorlike appearance. Case presentation: In the present case the inflammation involved all the layers of the gallbladder, the surrounding connective tissue, and part of the right lobe of the liver and right transverse colon. The clinical and radiological findings were suggestive of advanced carcinoma of the gallbladder. However, intraoperative frozen section investigation revealed xanthogranulomatous cholecystitis, for which simple cholecystectomy is the treatment of choice. Conclusions: The original cause of the condition is unclear in most cases. In the present case it is possible that rupture of the gallbladder in association with the patient's known history of trauma have initiated the process
Complications after BCG vaccine (bacilli Calmette-Guérin) occur rarely. They can reach from a local acute abscess to chronic ulceration's. Therapeutically concepts of these complications range from conservative to operative treatment. In the following case history recurrent soft tissue infections occurred after accidental inoculation with BCG vaccine. The time course of these recurrent infections with its therapeutic options is discussed and a treatment strategy is suggested. Currently, radical excision combined with antituberculotic treatment seems to be the most promising therapy of this specific soft tissue infection.
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.
