[Importance of biopsy in the diagnostic assessment of chronic wounds-position paper of the Initiative Chronische Wunden (ICW) e. V.] / Stellenwert der Biopsie in der Diagnostik chronischer Wunden ­ ein Positionspapier der Initiative Chronische Wunden (ICW) e. V.

Diagnostic assessment of chronic wounds is essential for the initiation of causal therapeutic treatment. For diagnostic classification of the wound genesis, it may be necessary to take a tissue sample for histological and/or microbiological processing. If there is clinical suspicion of a specific cause of the wound such as a neoplasm, an inflammatory dermatosis or a pathogen-induced wound, a tissue sample for further diagnosis is required immediately. If the ulceration does not respond sufficiently to adequate causal therapy, a tissue sample for further evaluation is recommended after 12 weeks. The choice of the correct sampling technique, further storage, transport and processing are just as decisive for a reliable result as the specific question for the diagnostic laboratory.

[The term mixed leg ulcer should no longer be used today]. / Der Begriff Ulcus cruris mixtum sollte heute nicht mehr verwendet werden.

A wound on the lower legs of patients with chronic venous insufficiency (CVI) and peripheral arterial disease (PAD) is today usually referred to as a mixed leg ulcer. This does not take into account the different stages of the diseases and, thus, their pathophysiological relevance. In everyday clinical practice, this often leads, among other things, to these patients not receiving compression therapy. The multidisciplinary professional association Initiative Chronische Wunden (ICW) e. V., therefore, recommends that this undifferentiated and misleading term should no longer be used. Instead, a leg ulcer with advanced CVI and concomitant PAD in stage I-IIb according to Fontaine or Rutherford category 0-3 should be classified as a venous leg ulcer, while a leg ulcer with advanced PAD in stage III or IV according to Fontaine or Rutherford category 4-6 and advanced CVI is termed an arteriovenous leg ulcer. A leg ulcer in advanced PAD stage IV according to Fontaine or Rutherford category 5 or 6 without advanced CVI is called an arterial leg ulcer. Other relevant comorbidities with an influence on wound healing should also be described separately.

[Incontinence-associated dermatitis: a position paper]. / Inkontinenzassoziierte Dermatitis: ein Positionspapier.

Incontinence-associated dermatitis (IAD) describes damage to the skin caused by repeated and prolonged contact with urine and/or feces. Patients of all ages can be affected; the diagnosis is preferably used in adults and adolescents. The predilection sites are perineal, perianal, the inner thighs and the convex areas of the buttocks. Increased moisture on the skin surface, increased pH, occlusion, feces digestive enzymes and repeated skin cleansing procedures are pathophysiologically relevant factors. Typical clinical signs of IAD are erythema, erosions, excoriations and pain. Diagnosis is often difficult because there are many relevant differential diagnoses, some of which may occur together with an IAD. In particular, pressure ulcer, contact dermatitis and intertrigo need to be differentiated and treated. Effective strategies of prevention and therapy of IAD are continence management, the use of efficient, absorbent products as well as consistent skin protection and care. IAD is a skin disease that is often not or incorrectly diagnosed. It should be treated as early as possible, together with the causative factors such a fecal and/or urinary incontinence, as otherwise it can lead to an unnecessarily long duration and severity of the symptoms.

Diagnosis and treatment of chronic wounds: current standards of Germany's Initiative for Chronic Wounds e. V.

The diagnosis and treatment of patients with chronic wounds is an enormous challenge in various disciplines of medicine. These very complex processes usually involve several experts of different medical specialties with varying educational backgrounds. A necessary basis for consistent communication and documentation is the use of unambiguous nomenclature. Therefore, the board of the German wound association, Initiative for Chronic Wounds (ICW) e.V., has started to define various terms and procedures. An easy to remember algorithm, in the form of the ABCDE rule, has been developed for the structured diagnosis of chronic wounds. The successful therapy of chronic wounds is then based on the causal treatment of the underlying, pathophysiological relevant diseases. M.O.I.S.T. a concept which helps health professionals in the systematic approach to the local treatment of patients with chronic wounds, in conforming to the most up-to-date scientific knowledge. By using consistent definitions and standards in wound care, it is possible to optimise current diagnostic and treatment strategies as well as to make them more easily understandable.
