Diagnostik von Beinödemen

Ödeme der unteren Extremitäten entsprechen immer einem pathologischen Zustand, der insbesondere bei Betroffenen mit chronischen Wunden einer Therapie bedarf. Weil die Ursachen dieser Ödeme sehr unterschiedlich und teilweise auch komplex sein können, sollte zuerst eine klinische und ggf. apparative Diagnostik erfolgen. Oft kann nach einer klinischen Untersuchung mit Testung des Stemmer- und Godet-Zeichens bereits eine klinische Verdachtsdiagnose gestellt werden. Als weiterführende apparative Diagnostik kann eine sonographische Untersuchung erfolgen. Messtechniken wie beispielsweise die Wasserplethysmographie gelten derzeit zwar als Goldstandard für Volumenmessungen, sind aber sehr aufwendig und fehleranfällig, sodass sie in der klinischen Routine heute kaum angewendet werden. Zusammenfassend wird empfohlen, für die Ödemdiagnostik eine klinische Untersuchung möglichst in Kombination mit einer Sonographie durchzuführen. Insbesondere zu Beginn der Entstauungsphase sollten regelmäßig Umfangsmessungen durchgeführt und dokumentiert werden. Diese Dokumentation ist für die Bewertung des therapeutischen Erfolgs von hoher Aussagekraft. // Edema of the lower extremities is always associated with a pathological condition that should be treated, especially in patients with chronic wounds. Because the underlying causes of edema can vary greatly and sometimes be complex, clinical and, if necessary, various diagnostic tests should also be performed. Often, a suspected clinical diagnosis can already be made after clinical inspection with testing of Stemmer's and Godet's signs. Sonographic examination should then be performed as the next diagnostic test. Although measurement techniques such as water plethysmography are currently considered gold standard for volume measurements, they are very complex and prone to error, so that they are rarely used in clinical routine today. In summary, it is recommended to perform a clinical examination, if possible in combination with sonography, for edema diagnosis. Especially at the beginning of the decongestion phase, regular circumferential measurements should be performed and documented. This documentation is of high relevance for evaluation of therapeutic success

Concurrent optical- and magnetic-stimulation-induced changes on wound healing parameters, analyzed by hyperspectral imaging : an exploratory case series

The effects of concurrent optical and magnetic stimulation (COMS) therapy on wound-healing-related parameters, such as tissue oxygenation and water index, were analyzed by hyperspectral imaging: an exploratory case series. Background: Oedema and inadequate perfusion have been identified as key factors in delayed wound healing and have been linked to reduced mitochondrial respiration. Targeting mitochondrial dysfunction is a promising approach in the treatment of therapy refractory wounds. This sub-study aimed to investigate the effects of concurrent optical and magnetic stimulation (COMS) on oedema and perfusion through measuring tissue oxygenation and water index, using hyperspectral imaging. Patients and methods: In a multi-center, prospective, comparative clinical trial, eleven patients with chronic leg and foot ulcers were treated with COMS additively to Standard of Care (SOC). Hyperspectral images were collected during patient visits before and after treatment to assess short- and long-term hemodynamic and immunomodulatory effects through changes in tissue oxygenation and water index. Results: The average time for wound onset in the eleven patients analyzed was 183 days, with 64% of them being considered unresponsive to SOC. At week 12, the rate of near-complete and complete wound closure was 64% and 45%, respectively. COMS therapy with SOC resulted in an increased short-term tissue oxygenation over the 8-week treatment phase, with oxygen levels decreasing in-between patient visits. The study further found a decrease in tissue water content after the therapy, with a general accumulation of water levels in-between patient visits. This study’s long-term analysis was hindered by the lack of absolute values in hyperspectral imaging and the dynamic nature of patient parameters during visits, resulting in high interpatient and intervisit variability. Conclusions: This study showed that COMS therapy as an adjunct to SOC had a positive short-term effect on inflammation and tissue oxygenation in chronic wounds of various etiologies. These results further supported the body of evidence for safety and effectiveness of COMS therapy as a treatment option, especially for stagnant wounds that tended to stay in the inflammatory phase and required efficient phase transition towards healing

Moisture‐associated skin damage (MASD) ::a best practice recommendation from Wund‐D.A.CH.

Wund‐D.A.CH., as the umbrella organization of German‐speaking wound treatment societies, has currently developed a best practice recommendation for skin damage caused by body fluids, which is known as moisture‐associated skin damage (MASD) in English‐speaking countries. In this expert consensus, the diseases incontinence‐associated dermatitis (IAD), intertriginous dermatitis, including intertrigo, gram‐negative bacterial toe web infection and toxic contact dermatitis, including periwound and peristomal dermatitis are presented in a differentiated manner. A common feature of these clinical diseases is a deterioration of skin integrity due to prolonged exposure to body fluids such as urine, stool, sweat or wound exudate with associated physical‐irritative and/or chemical irritation. In addition, other comorbidities and cofactors play an important role. The diagnosis of these interdisciplinary and interprofessionally relevant MASD is difficult in everyday clinical practice because there are currently no uniform definitions and many relevant differential diagnoses. Effective strategies for the prevention and therapy of these skin diseases are, for example, continence management, use of efficient, absorbent aids with good retention as well as consistent skin protection and adequate skin care. Another important aspect is the education of patients and relatives about the origin, treatment and prevention of MASD
