Summary Background: To evaluate the implementation of the guidelines of the German Society of Phlebology for venous crural ulcer a survey was conducted during the annual meeting of the German Society of Phlebology 2008 in Bochum. Methods: All 719 medical participants got an anonymized questionnaire asking for supply of crural ulcer in their institution. Results: The recurrent 66 questionnaires (9.2%) were filled by colleagues from practice or hospital, mostly surgeons, dermatologists, phlebologists and vascular surgeons. As basic diagnostics vein doppler (56.1%), duplex (75.8%) or measurement of brachial-ankleindex (83.3%) were performed. Compression therapy is used in all institutions. Mainly used wound dressings are polyurethane foam dressings, alginates, hydrocolloids and silver dressings. About 2/3 conduct surgical therapy of ulcers. Conclusion: Supply of ulcus cruris by the participants of the annual meeting of the DGP corresponds mainly, but not in all aspects to the guidelines. Further efforts for a spread of the guidelines are necessary.

The Great War

Isaac Bayley Balfour was a systematist specializing in Sino-Himalayan plants. He enjoyed a long and exceptionally distinguished academic career yet he was knighted, in 1920, “for services in connection with the war”. Together with an Edinburgh surgeon, Charles Cathcart, he had discovered in 1914 something well known to German doctors; dried Sphagnum (bog moss) makes highly absorptive, antiseptic wound dressings. Balfour directed the expertise and resources of the Royal Botanic Garden, Edinburgh (of which he was Keeper), towards the identification of the most useful Sphagnum species in Britain and the production of leaflets telling collectors where to find the moss in Scotland. By 1918 over one million such dressings were used by British hospitals each month. Cathcart's Edinburgh organisation, which received moss before making it into dressings, proved a working model soon adopted in Ireland, and later in both Canada and the United States.

Background: Cellulose Nanofibrils (CNFs) are natural nanomaterials with nanometer dimensions. Compared with ordinary cellulose, CNFs own good mechanical properties, large specific surface areas, high Young's modulus, strong hydrophilicity and other distinguishing characteristics, which make them widely used in many fields. This review aims to introduce the preparation of CNFs-based hydrogels and their recent biomedical application advances. Methods: By searching the recent literatures, we have summarized the preparation methods of CNFs, including mechanical methods and chemical mechanical methods, and also introduced the fabrication methods of CNFs-based hydrogels, including CNFs cross-linked with metal ion and with polymers. In addition, we have summarized the biomedical applications of CNFs-based hydrogels, including scaffold materials and wound dressings. Results: CNFs-based hydrogels are new types of materials that are non-toxic and display a certain mechanical strength. In the tissue scaffold application, they can provide a micro-environment for the damaged tissue to repair and regenerate it. In wound dressing applications, it can fit the wound surface and protect the wound from the external environment, thereby effectively promoting the healing of skin tissue. Conclusion: By summarizing the preparation and application of CNFs-based hydrogels, we have analyzed and forecasted their development trends. At present, the research of CNFs-based hydrogels is still in the laboratory stage. It needs further exploration to be applied in practice. The development of medical hydrogels with high mechanical properties and biocompatibility still poses significant challenges.

This work presents the development of multifunctional therapeutic membranes based on a high-performance block copolymer scaffold formed by polyether (PE) and polyamide (PA) units (known as PEBA) and layered double hydroxide (LDH) biomaterials, with the aim to study their uses as wound dressings. Two LDH layer compositions were employed containing Mg2+ or Zn2+, Fe3+ and Al3+ cations, intercalated with chloride anions, abbreviated as Mg-Cl or Zn-Cl, or intercalated with naproxenate (NAP) anions, abbreviated as Mg-NAP or Zn-NAP. Membranes were structurally and physically characterized, and the in vitro drug release kinetics and cytotoxicity assessed. PEBA-loading NaNAP salt particles were also prepared for comparison. Intercalated NAP anions improved LDH–polymer interaction, resulting in membranes with greater mechanical performance compared to the polymer only or to the membranes containing the Cl-LDHs. Drug release (in saline solution) was sustained for at least 8 h for all samples and release kinetics could be modulated: a slower, an intermediate and a faster NAP release were observed from membranes containing Zn-NAP, NaNAP and Mg-NAP particles, respectively. In general, cell viability was higher in the presence of Mg-LDH and the membranes presented improved performance in comparison with the powdered samples. PEBA containing Mg-NAP sample stood out among all membranes in all the evaluated aspects, thus being considered a great candidate for application as multifunctional therapeutic dressings.
