A novel topical therapy for resistant and early peristomal pyoderma gangrenosum.

Peristomal pyoderma gangrenosum (PPG) is an under-recognised and difficult condition to treat. We describe a case series using a novel topical combination therapy that promotes wound healing and allows for adhesion of the stoma appliance. A crushed oral prednisolone tablet mixed with Stomahesive Protective Powder (ConvaTec) was applied topically to seven patients with PPG and resulted in pain relief and wound healing in six of seven patients. Only one patient experienced recurrence. The novel topical therapy we describe is cost-effective, readily available, and easily applied in any inpatient or outpatient setting.

The development and testing of a skin tear risk assessment tool.

The aim of the present study is to develop a reliable and valid skin tear risk assessment tool. The six characteristics identified in a previous case control study as constituting the best risk model for skin tear development were used to construct a risk assessment tool. The ability of the tool to predict skin tear development was then tested in a prospective study. Between August 2012 and September 2013, 1466 tertiary hospital patients were assessed at admission and followed up for 10 days to see if they developed a skin tear. The predictive validity of the tool was assessed using receiver operating characteristic (ROC) analysis. When the tool was found not to have performed as well as hoped, secondary analyses were performed to determine whether a potentially better performing risk model could be identified. The tool was found to have high sensitivity but low specificity and therefore have inadequate predictive validity. Secondary analysis of the combined data from this and the previous case control study identified an alternative better performing risk model. The tool developed and tested in this study was found to have inadequate predictive validity. The predictive validity of an alternative, more parsimonious model now needs to be tested.

Identification of risk factors associated with the development of skin tears in hospitalised older persons: a case-control study.

To identify the risk factors associated with the development of skin tears in older persons four hundred and fifty three patients (151 cases and 302 controls) were enrolled in a case-control study in a 500-bed metropolitan tertiary hospital in Western Australia between December 2008 and June 2009. Case eligibility was defined by a skin tear on admission, which had occurred in the last 5 days; or, a skin tear developed during hospitalisation. For each case, two controls who did not have a skin tear and had been admitted within 1 day of the case, were also enrolled. Data collected from the nursing staff and inpatient medical records included characteristics known, or hypothesised, to be associated with increased vulnerability to skin tears. Data analysis included a series of multivariate stepwise regressions to identify a number of different potential explanatory models. The most parsimonious model for predicting skin tear development comprised six variables: ecchymosis (bruising); senile purpura; haematoma; evidence of a previously healed skin tear; oedema; and inability to reposition oneself independently. The ability of these six characteristics to predict who among older patients could subsequently develop a skin tear now needs to be determined by a prospective study.
