Arteriolosclerotic ulcer of Martorell
No full textIn 1945, Martorell described ischaemic leg ulcers in patients with hypertension. He suggested that the ischaemic necrosis was secondary to a hypertensive arteriolar disease and referred to them as 'hypertensive ischaemic ulcers'. In recent years, the specific entity of these ulcers has been questioned. Others claim they have a much higher incidence, but presume the diagnosis is frequently missed. Almost 900 cases of Martorell's ulcers have been reported in literature since the first description. A systematic review and comprehensive search of literature (evidence-based) was needed to characterize this type of ulcer. Based on aetiology and histopathology, it seems to be justified to maintain the name 'arteriolosclerotic ulcer of Martorell'. We conclude that the arteriolosclerotic ulcer of Martorell is a specific entity with its own clinical and histological diagnostic keys, wound management and preventive measures. We introduce a set of criteria that may be used to facilitate diagnosing arteriolosclerotic ulcer of Martorell as well as a flowchart that includes diagnosis, treatment and prevention of this particular type of vascular leg ulcer

Ulcus hypertonicum Martorell - Ein Modell der ischämischen subkutanen Arteriolosklerose
No full textDas Ulcus hypertonicum Martorell (1) ist die häufigste Form von ischämischer subkutaner Arteriolosklerose. Zugrunde liegend findet sich bei Patienten mit einer langjährigen, meistens gut eingestellten arteriellen Hypertonie eine stenosierende Arteriolosklerose in der Subkutis, welche im Endstadium zu Hautinfarkten am Unterschenkel führt. Klinisch findet sich eine nekrotisierende Livedo racemosa, die sich regelhaft am laterodorsalen Unterschenkel oder über der Achillessehne lokalisiert. 60 °/o der Patienten haben auch einen Diabetes, oft im Rahmen eines metabolischen Syndroms, aber 40 °/o sind "schlanke Hypertoniker" (2). Dieses klinische Bild wird aufgrund des lividen, fortschreitenden Wundrandes und der sehr stark ausgeprägten (Ischämie-) Schmerzen von Klinikerlnnen, welche das Krankheitsbild nicht kennen, sehr oft als Pyoderma gangraenosum oder als nekrotisierende Vaskulitis fehlgedeutet Wenn dann noch eine oberflächliche Hautbiopsie vom Ulkusrand entnommen wird, kann es gut sein, dass die Histologie mit einem Pyoderma gangraenosum vereinbar ist. Daraus wird als nächster Schritt (3) das falsche Therapiekonzept abgeleitet, nämlich Immunsuppression und Vermeiden jeglicher Chirurgie. Dabei wäre die Nekrosektomie mit Spalthautverpflanzung in den ausgedehnteren Fällen von Ulcus hypertonicum Martorell die Behandlung der Wahl (4). Etwa 70 % der Histologien des Ulcus hypertonicum Martorell sind mit der Histologie der sogenannten Kalziphylaxie identisch. Daher liegt die Hypothese nahe, dass das Ulcus hypertonicum Martorell und die Kalziphylaxie eine gemeinsame Pathogenese haben.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Pulmonary hypertension in patients with Martorell hypertensive leg ulcer: a case control study
No full textBACKGROUND: Martorell hypertensive ischemic leg ulcer (Martorell ulcer) is characterized by distinct alterations in the arteriolar wall of subcutaneous vessels, leading to progressive narrowing of the vascular lumen and increase of vascular resistance. These changes are similar to the alterations observed in pulmonary arterioles in patients with chronic pulmonary hypertension (PH). This study was aimed to assess an association between the two disorders. METHODS: In this case-control-study, 14 patients with Martorell ulcer were clinically assessed for the presence of pulmonary hypertension using transthoracic Doppler echocardiography. Data from patients were compared to 28 matched hypertensive controls. RESULTS: Systolic pulmonary arterial pressure (sPAP) in patients with Martorell ulcer was significantly higher than in the control group (33.8+/-16.9 vs 25.3+/-6.5 mmHg, p=0.023); the prevalence of pulmonary hypertension was 31% (5/14) in patients and 7% (2/28) in controls (p=0.031). No differences were seen in left heart size and function between patients and controls. CONCLUSION: This study provides first evidence that subcutaneous arteriolosclerosis, the hallmark of Martorell ulcer, is associated with PH. These findings suggest that patients with Martorell leg ulcer might be at significant risk to develop elevated pulmonary arterial pressure. Patients with leg ulcers who present with dyspnea should be evaluated by echocardiography for the presence of pulmonary hypertension
