Reduction of abdominal adhesions using composite collagen-GAG implants for ventral hernia repair.

Structural biomaterials can restore abdominal wall integrity but may cause adhesions to the underlying viscera. Collagen-glycosaminoglycan (CG) matrices induce the formation of connective tissue and may reduce adhesion formation to permanent biomaterials such as polypropylene (PP) mesh. Composite implants were created by interposing PP mesh within a porous CG matrix created composite implants. The implants were cross-linked with glutaraldehyde one group (CG-G/PP) or left untreated (CG-nG/PP) and compared to PP mesh. At 4 weeks, the abdominal wall was assessed for the degree of adhesions. The composite implants developed a nascent connective tissue-like structure that reduced adhesions to the bowel. The thickest connective tissue developed in the CG-G/PP group (0.7 +/- 0.1 mm) and thinnest in the PP mesh (0.05 +/- 0.01 mm). The surface area covered with adhesions was greatest in the PP group (72 +/- 17%) compared with the CG-G/PP group (28 +/- 15%) or the CG-nG/PP group (21 +/- 8%). Bowel preferentially adhered to the PP mesh, whereas omentum had some adherence to all constructs. Integrating a biodegradable extracellular matrix analog with a permanent structural biomaterial reduced adhesions in this animal model. Alterations in cross-linking of the CG matrix altered the biological response. This technology may be useful in reconstructive surgery by reducing adhesion formation, while maintaining the strength of permanent structural biomaterials.

[The language of medicine in Switzerland 1920 to 1995].

AIM OF STUDY: It is generally accepted that since the end of the Second World War, English has become the main language in the medical field in Switzerland, but scarcely any objective data are available on the development of this process in this country. The aim of the present study was to analyze the frequency of the different languages in the literature references in articles published in the Swiss Medical Weekly over the past 75 years, with special attention to the possible differences existing between articles originating in German-speaking Switzerland and French-speaking Switzerland. METHODS: The language of publication of 47,160 literature references cited in 2489 original articles published in the Swiss Medical Weekly between 1920 and 1995 was established. The 1730 articles published in German contained 32,607 assessable references; the 759 articles published in French contained 14,553 assessable references. RESULTS: The percentages of literature references in German, French and English cited in the articles written in German were, respectively, 83.6%, 9.1% and 5.9% in 1920; 68.6%, 7.2% and 18.3% in 1945; 30.7%, 5.6% and 61.9% in 1970; 11.3%, 1.5% and 86.7% in 1995. The percentages of literature references in French, German and English cited in the articles written in French were, respectively, 61.1%, 31.8% and 4.0% in 1920; 30.6%, 39.3% and 26.5% in 1945; 19.8%, 9.6% and 69.7% in 1970; 7.4%, 2.4% and 90.0% in 1995. CONCLUSIONS: (1) Between 1945 and 1995 the percentage of literature references in English has increased continuously, while the percentages of references in German and French have decreased. (2) English replaced German as the main language of medicine towards 1955 in French-speaking Switzerland and towards 1965 in German-speaking Switzerland. (3) During the whole period studied (1920-1995), French-speaking authors cited publications in German more frequently than German-speaking authors cited publications in French. (4) The evolution of the relative importance of the languages in German-speaking Switzerland is very similar to that previously described in Germany and Austria. (5) In French-speaking Switzerland, on the other hand, the evolution of the relative importance of the different languages differs very considerably from that previously described in France.

[English or German? The language of medicine based on the bibliographic data appearing in the Deutsche Medizinische Wochenscrift (1920 to 1995)].

AIM OF STUDY: To describe and analyse the frequency of English and German in the bibliographical references from the original articles published in "Deutsche Medizinische Wochenschrift" during the past 75 years (1920-1995). METHODS: The language of publication of 16,001 references from 800 original papers, at the rate of 50 articles per year at intervals of 5 years, was determined. RESULTS: The percentage of references in German has been decreasing during the whole studied period: 90.1% in 1920, 85.9% in 1935, 75.8% in 1950, 44.1% in 1965, 31.0% in 1980, and 16.4% in 1995. The percentage of references in English, on the contrary, has continued to increase: 3.2% in 1920, 10.6% in 1935, 21.5% in 1950, 50.0% in 1965, 66.2% in 1980, and 82.8% in 1995. CONCLUSION: Even though the importance of English has been increasing during the entire considered period, it did not clearly supplant German as the main language of medicine in Germany until 1975.
