Abstract Background. The use of maggots to digest necrotic tissue as a form of wound debridement has a long history in medicine. Necrotizing fasciitis of the neck has a high mortality rate despite aggressive surgical and medical intervention. The use of maggots in this disease has been reported only once before. Methods. We report the case of a 73-year-old woman, who underwent neck dissection and had necrotizing fasciitis of the neck develop shortly after. After initial surgical wound debridement, we used maggots as a biosurgical method for further debridement. A net containing 100 maggots (Biobag; BioMonde, Germany) was used. Results. Daily wound dressing showed rapid improvement of the wound; 4 days after beginning treatment, the wound was free of necroses. Conclusion. In this case, we could avoid repeated surgical wound debridement with the use of sterile maggots. The frequently rapid progression of necrotizing fasciitis could be well controlled. © 2004 Wiley Periodicals, Inc. Head Neck26: 747,750, 2004 [source]

Wounds of the pastern and foot region managed with phalangeal casts: 50 cases in 49 horses (1995,2006)

Objective Describe the use of a phalangeal cast as treatment for wounds in the pastern and foot region of horses. Secondly, to evaluate the healing and soundness of horses treated with phalangeal casts. Design Retrospective study of 49 horses. Procedures Medical records of 49 horses that were treated with a phalangeal cast for 50 cases of wounds in the pastern and foot region at equine referral hospitals from 1995 to 2006 were reviewed and follow-up information was obtained. Results Treatment consisted of wound debridement, lavage, wound closure (28 wounds), cast application and antibiotics (84%). At follow-up, the majority of horses were sound (42 of 47 wounds, 89.4%), three horses were still lame and one horse was euthanased because of persistent lameness. Three horses were lost to follow-up. There was no statistical difference between the outcomes of horses treated acutely (<24 h) or after a 24-h delay. Similarly, the involvement of synovial structures in the wound did not significantly influence outcome. Conclusions In this study, wounds involving the pastern and foot that were treated with a phalangeal cast carried a good prognosis for soundness (89.4%) and cosmetic healing (89.5%). The phalangeal casts were well-tolerated and effective. [source]

Expression of the CXCR6 on polymorphonuclear neutrophils in pancreatic carcinoma and in acute, localized bacterial infections

CLINICAL & EXPERIMENTAL IMMUNOLOGY, Issue 2 2008
M. M. Gaida
Summary The chemokine receptor CXCR6 has been described on lymphoid cells and is thought to participate in the homing of activated T-cells to non-lymphoid tissue. We now provide evidence that the chemokine receptor CXCR6 is also expressed by activated polymorphonuclear neutrophils (PMN) in vivo: Examination of biopsies derived from patients with pancreatic carcinoma by confocal laser scan microscopy revealed a massive infiltration of PMN that expressed CXCR6, while PMN of the peripheral blood of these patients did not. To answer the question whether CXCR6 expression is a property of infiltrated and activated PMN, leucocytes were collected from patients with localized soft tissue infections in the course of the wound debridement. By cytofluorometry, the majority of these cells were identified as PMN. Up to 50% of these PMN were also positive for CXCR6. Again, PMN from the peripheral blood of these patients were nearly negative for CXCR6, as were PMN of healthy donors. In a series of in vitro experiments, up-regulation of CXCR6 on PMN of healthy donors by a variety of cytokines was tested. So far, a minor, although reproducible, effect of tumour necrosis factor (TNF,) was seen: brief exposure with low-dose TNF, induced expression of CXCR6 on the surface of PMN. Furthermore, we could show an increased migration of PMN induced by the axis CXCL16 and CXCR6. In summary, our data provide evidence that CXCR6 is not constitutively expressed on PMN, but is up-regulated under inflammatory conditions and mediates migration of CXCR6-positive PMN. [source]
