Many chronic wounds have a limited blood supply and contain necrotic tissue that must be debrided. The effect of collagenase, an enzymatic debriding agent, has been studied in acute but not in chronic wounds. The purpose of this in vivo study is to evaluate the effect of collagenase on wound healing in ischemic wounds. The ears of eight young New Zealand White rabbits were rend...

In a randomised, double blind, controlled study the ability of 5% lignocaine ointment to reduce the behavioural response to heel lance in 30 healthy neonates was assessed. Five per cent lignocaine ointment applied to the heel under an occlusive dressing for one hour before heel prick did not reduce the infants' behavioural response to the heel prick procedure.

INTRODUCTION The pain of acute herpes zoster (shingles) is severe and difficult to control. The medications used to control pain have a variety of important and potentially serious side effects. To the best of my knowledge, this is the first case report of using a plain topical occlusive dressing to reduce the pain of herpes zoster, avoiding the use of medication. CASE PRESENTATION A 40-year-...

BACKGROUND The vacuum-assisted closure device is widely used clinically, yet its mechanisms of action are incompletely understood. In this study, the authors designed a partially splinted full-thickness murine vacuum-assisted closure model to better understand the mechanism of action of the vacuum-assisted closure device. METHODS Full-thickness wounds (n = 10 per group) were excised in diabet...

BACKGROUND There is growing evidence of improved healing of full- and partial-thickness cutaneous wounds in wet and moist environments. Retention of biologic fluids over the wound prevents desiccation of denuded dermis or deeper tissues and allows faster and unimpeded migration of keratinocytes over the wound surface. It allows also the naturally occurring cytokines and growth factors to exert ...

The pretibial myxedema is a manifestation of Graves' disease characterized by accumulation of glycosaminoglycans in the reticular dermis. The dermopathy is self-limiting but in some cases may cause cosmetic and functional damage. Conventional treatment is use of topical steroids under occlusive dressing, however the intralesional application has shown good results. We present a case of pretibia...

Approximately 70% of all people with severe burns die from related infections despite advances in treatment regimens and the best efforts of nurses and doctors. Silver ion-eluting wound dressings are available for overcoming this problem. However, there are reports of deleterious effects of such dressings due to cellular toxicity that delays the healing process, and the dressing changes needed ...

To prevent wound dehydration and bacterial penetration, a wound dressing should be occlusive, but on the other hand it should also be permeable for wound exudate to prevent bullae formation. To meet these requirements a new type of polyurethane wound dressing which consists of a microporous top layer (pore size less than 0.7 mum) supported by a sublayer with a highly porous sponge-like structu...
