[Model aeroplanes: a not to be ignored source of complex injuries]. / Modellflug: Eine nicht zu unterschätzende Quelle für komplexe Verletzungen.

With the incidence of work-related injuries decreasing, we continue to observe an unchanged trend in leisure-related accidents. As in any other hobby, model flying devices bear the risk for accidents among builders and flyers ranging from skin lacerations to complicated and even life-threatening injuries. The fast-moving razor-sharp propeller blades predominantly cause trauma to the hands and fingers resulting in typical multiple parallel skin injuries also affecting structures deep to the dermis (e. g., tendons, vessels and nerves). The resultant clinical management involves complex reconstructive surgical procedures and prolonged rehabilitative follow-up. Improving the legal framework (e. g., warnings by the manufacturer) on the one hand, providing informative action and sensitising those affected on the other, should form a basis for an altered prevention strategy to reduce model flying device-related injuries in the future.

Use of 2-octyl cyanoacrylate together with a self-adhering mesh (Dermabond™ Prineo™) for skin closure following abdominoplasty: an open, prospective, controlled, randomized, clinical study.

BACKGROUND: Abdominoplasty is one of the most commonly performed procedures in plastic surgery. The appearance of the scar is a major factor that contributes to the aesthetic outcome of the procedure and depends largely on the technique of wound closure. The new Prineo™ wound closure system was introduced to combine the effectiveness of 2-octyl cyanoacrylate (Dermabond™) together with a self-adhering mesh. METHODS: Fifty-two women and eight men aged between 21 and 65 years who were scheduled for abdominoplasty were included in the study. The total operating times after abdominoplasty of the traditional wound closure technique and the Prineo™-type wound closure technique were compared. Furthermore, an analysis comparing the cost of the two methods was performed. Two weeks after surgery the wounds were examined and graded using the Hollander Cosmesis Scale. At the 6- and 12-month follow-ups, the aesthetic outcome of the abdominal scar was evaluated using the Vancouver Scar Scale. Twelve months after surgery, the patients were asked to answer their part of the Patient Scar Assessment Scale. RESULTS: The mean total operating time for the new skin closure system was statistically significantly shorter than that of intradermal sutures. The mean price difference per patient was 104.27 (134.79$) in favor of Prineo™. The Hollander Cosmesis Scale indicated a significantly more favorable overall result with Prineo™ at 2 weeks after surgery. The Vancouver Scar Scale demonstrated a better cosmetic outcome in favor of Prineo™ 6 and 12 months after surgery. The Patient Scar Assessment Scale scores 12 months after surgery indicated that the patients noted significantly less pain, thickness, and irregularity with Prineo™. CONCLUSION: Based on our results, we conclude that Prineo™ is a safe and effective substitute for superficial skin closure, with good cosmetic results and no increase in wound complications. The use of Prineo™ decreases operative time and cost and enhances the patient's postoperative comfort.

The properties of the "ideal" donor site dressing: results of a worldwide online survey.

Split skin grafting is a widely used technique for reconstructing skin defects. Although a vast number of different coverage options for donor sites have become available in daily clinical practice, no optimum dressing material has been found to date. For this reason, we conducted a globally-distributed online survey to poll for the properties of such an "ideal" donor site dressing, possibly leading to an improved clinically-driven direction of future wound dressing developments. A total of 69 respondents from 34 countries took part in the questionnaire, resulting in a response rate of 13.8% (69/500) over a 1-month period. The majority of respondents rated the characteristics of an "ideal" donor site dressing to be either "essential" or "desirable" as follows: lack of adhesion to the wound bed ("essential": 31/69, 44.9%; "desirable": 30/69, 43.5%); pain-free dressing changes ("essential": 38/69, 55.1%; "desirable": 30/69, 43.5%); absorbency ("essential": 27/69, 39.1%; "desirable": 33/69, 47.8%); ease of removal ("essential": 37/69, 53.6%; "desirable": 27/69, 39.13%). With regard to the desired frequency of dressing changes, respondents preferred "no dressing change until the donor site has healed" (51/69, 73.9%) in the majority of cases, followed by "twice weekly" (10/69, 14.5%), "alternate days" (5/69, 7.2%) and "daily" (3/69, 4.3%). With regard to the design of the dressing material, the majority of participants preferred a one-piece (composite) dressing product (44/69, 63.8%). The majority of respondents also denied the current availability of an "ideal" donor site dressing (49/69, 71%). The strength of this study was the remarkable geographic distribution of responses; all parts of the world were included and participated. We believe that this globally conducted online survey has polled for the properties of the "ideal" donor site dressing and possibly will lead to an improved clinically-driven direction of future wound dressing development.

Les greffes de peau mince sont largement utilisées pour reconstruire les défauts de la peau. Même si un grand nombre de différentes options de couverture des sites donneurs sont devenus disponibles dans la pratique clinique quotidienne, à ce jour, aucun matériel de pansement optimum n'a été trouvé. Pour cette raison, nous avons mené un sondage en ligne mondialement distribué à scrutin pour les propriétés d'un tel pansement de site donneur «idéal¼, qui peut conduire à une meilleure direction en ce qui concerne des futurs développements de pansement. Un total de 69 répondants de 34 pays ont été inclus dans le questionnaire, soit un taux de réponse de 13,8% (69/500) sur une période de 1 mois. La majorité des répondants ont évalué les caractéristiques d'un pansement «idéal¼ pour les sites donneurs d'être «essentiel¼ ou «souhaitable¼ comme suit: le manque d'adhérence au lit de la plaie («essentiel¼: 31/69, 44,9%; «souhaitable¼ : 30/69, 43,5%), le changement de pansement sans douleur («essentiel¼: 38/69, 55,1%; «souhaitable¼: 30/69, 43,5%); l'absorption («essentiel¼: 27/69, 39,1% ; «souhaitable¼: 33/69, 47,8%), la facilité de retrait («essentiel¼: 37/69, 53,6%; «souhaitable¼: 27/69, 39.13%), par rapport à la fréquence souhaitée des changements de pansements, les répondants préféraient «aucun changement de pansement jusqu'à ce que le site donneur est guéri¼ (51/69, 73,9%) dans la majorité des cas, suivi par «deux fois par semaine¼ (10/69, 14,5%), «deux jours¼ (5/69 , 7,2%) et «quotidienne¼ (3/69, 4,3%). En ce qui concerne la conception du matériel de pansement, la majorité des participants ont préféré une seule pièce (composite) (44/69, 63,8%). La majorité des répondants a également nié l'existence actuelle d'un pansement au site donneur «idéal¼ (49/69, 71%). La force de cette étude est la répartition géographique remarquable de réponses ; toutes les parties du monde ont été inclus et ont participé. Nous croyons que cette enquête en ligne, menée au niveau mondial, concernant les propriétés du pansement «idéal¼ pour les sites donneurs se traduira, éventuellement, par une amélioration future dans le développement des pansements.
