Inflammatory ulcers

Vasculitic Ulcers

Vasculitic ulcers are an emerging problem in wound care that needs to be well defined and adequately approached by caregivers. Cutaneous vasculitis includes several inflammatory disorders that compromise microvessels and specifically the cutaneous vascular system: arterioles, capillaries, postcapillary venules. The pathogenetic role of circulating immunocomplexes and autoantibodies (antineutrophil antibodies) in these diseases has been widely demonstrated in animal models and in humans. Vasculitis can be limited to the skin or represent the cutaneous signs in case of systemic vasculitis with visceral involvement. The injury of cutaneous microvessels may result in impairment of blood flow and consequent focal ischemia and formation of skin ulcers. The ulcers are often multiple and localized on the lower leg and foot where the microcirculatory anatomy and rheologic dynamics are predisposing factors. Approximately 3% to 5% of skin ulcers may be caused by a vasculitic disorder.

Inflammatory ulcers

Skin ulcerations may develop as a manifestation of a variety of different diseases or may result from some nondisease phenomena. Inflammatory ulcers refer specifically to those ulcerations in which inflammation is the primary pathologic process resulting in lesion formation; that is, inflammation is the cause rather than the consequence of the ulcer. This review will consider several types of inflammatory ulcers that the clinician may encounter in his or her practice.

Contents. MEASURE: A proposed assessment framework for developing best practice recommendations for wound assessment

The effective management of nonhealing wounds is based on a complete patient history, a detailed initial assessment of the wound, and an analysis of probable causative factors. This information is used to individualize a management strategy to the underlying pathophysiology preventing healing and to implement appropriate wound interventions. Regular reassessment of progress toward healing and appropriate modification of the intervention are also necessary. Accurate and clinically relevant wound assessment is an important clinical tool, but this process remains a substantial challenge. Wound assessment terminology is nonuniform, many questions surrounding wound assessment remain unanswered, agreement has yet to be reached on the key wound parameters to measure in clinical practice, and the accuracy and reliability of available wound assessment techniques vary. This article, which resulted from a meeting of wound healing experts in June 2003, reviews clinically useful wound measurement approaches, provides an overview of the principles and practice of chronic wound assessment geared to a clinical audience, and introduces a simple mnemonic, MEASURE. MEASURE encapsulates key wound parameters that should be addressed in the assessment and management of chronic wounds: Measure (length, width, depth, and area), Exudate (quantity and quality), Appearance (wound bed, including tissue type and amount), Suffering (pain type and level), Undermining (presence or absence), Reevaluate (monitoring of all parameters regularly), and Edge (condition of edge and surrounding skin). This article also provides some preliminary recommendations targeted to developing best practice guidelines for wound assessment.
