Acellularization-induced changes in tensile properties are organ specific: an in-vitro mechanical and structural analysis of porcine soft tissues

Schleifenbaum, Stefan, Prietzel, Torsten, Aust, Gabriela, Boldt, Andreas, Fritsch, Sebastian, Keil, Isabel, Koch, Holger, Möbius, Robert, Scheidt, Holger A., Wagner, Martin F. X., Hammer, Niels January 2016 (has links)
Introduction: Though xenogeneic acellular scaffolds are frequently used for surgical reconstruction, knowledge of their mechanical properties is lacking. This study compared the mechanical, histological and ultrastructural properties of various native and acellular specimens. Materials and methods: Porcine esophagi, ureters and skin were tested mechanically in a native or acellular condition, focusing on the elastic modulus, ultimate tensile stress and maximum strain. The testing protocol for soft tissues was standardized, including the adaption of the tissue’s water content and partial plastination to minimize material slippage as well as templates for normed sample dimensions and precise cross-section measurements. The native and acellular tissues were compared at the microscopic and ultrastructural level with a focus on type I collagens. Results: Increased elastic modulus and ultimate tensile stress values were quantified in acellular esophagi and ureters compared to the native condition. In contrast, these values were strongly decreased in the skin after acellularization. Acellularization-related decreases in maximum strain were found in all tissues. Type I collagens were well-preserved in these samples; however, clotting and a loss of cross-linking type I collagens was observed ultrastructurally. Elastins and fibronectins were preserved in the esophagi and ureters. A loss of the epidermal layer and decreased fibronectin content was present in the skin. Discussion: Acellularization induces changes in the tensile properties of soft tissues. Some of these changes appear to be organ specific. Loss of cross-linking type I collagen may indicate increased mechanical strength due to decreasing transverse forces acting upon the scaffolds, whereas fibronectin loss may be related to decreased load-bearing capacity. Potentially, the alterations in tissue mechanics are linked to organ function and to the interplay of cells and the extracellular matrix, which is different in hollow organs when compared to skin.

Modeling the propagation of the consumption of two emergent businesses: Fitness Practice and Plastic Surgery

Al-Kasadi, Mohammed Saleh Salim 22 September 2014 (has links)
In recent years there has emerged a new trend focused on the body image in the Western countries. Our society is concerned with people's physical appearance and ideal body image. As consequence of this trend, two businesses emerge: fitness centers and plastic surgery clinics. Traditionally the consumers' expenditure in these services and goods has been considered a luxury especially during the economic slowdown. However, in the recent times, (at end of 2000s both service sectors are showing an increasing trend in terms of activity and business size). Thus, customers have seen the practice of fitness and plastic surgery procedures as a necessity rather than a luxury. The two kinds of products considered: fitness practice and plastic surgery procedures are of different nature; however they share several commonalities from the analysis point of view. In particular, referred to the fitness practice business, this involves a parallel increase of related economic sectors such as sports clothing, energy drinks and sports equipment. Related to the Spanish population who exercise regularly, this has evolved from 27% in 2005 to 35% in 2010, which shows a significant increase of the population sportive practices. A significant example of this trend is the fact that in 2009 the 74% of the Spanish public gyms had a fitness room for bodybuilding. On contrast, related to the market of plastic surgery measured by volume of activity, Spain occupies the level 13th position of the international ranking, which is headed by USA. The plastic surgery market embraces low invasive (non surgical) and high invasive (surgical) plastic surgery procedures; between both types, more than 300,000 thousands procedures are performed annually mainly by women in Spain. / Al-Kasadi, MSS.

Hand Injury from Powered Wood Splitters

Lindqvist, Aron January 2010 (has links)
The purpose of this study on hand injury from powered wood splitters was to describe injury epidemiology and anatomy, to rate injury severity, to evaluate the outcome after injury and to describe factors of possible importance for the occurrence of injury. By searching a computerized patient registry, 131 patients injured by wood splitters from 1995 to 2001 were identified. Information was obtained from hospital records and radiographs, a written questionnaire and a structured telephone interview. Injury severity was rated according to the Hand Injury Severity Scoring System (HISS system) and the Injury Severity Score (ISS). Outcome was evaluated with the Disabilities of the Arm, Shoulder and Hand outcome questionnaire (DASH) and, in 26 of the most severely injured patients, with the Sollerman test. Forty-six percent of the injuries occurred during April or May. Wedge splitters caused 82 % of all injuries and most often injured the index finger, while screw splitters caused 18 % of all injuries and most often injured the metacarpus. Screw splitters caused palmar perforation and thumb avulsion. Sixty-three percent of all patients had an amputation or devascularising injury. The reliability of HISS rating was good. The mean Hand Injury Severity Score (HISS) was 63 which is equivalent to a severe hand injury. The mean ISS was 3.7. Nineteen percent of patients had minor, 31 % had moderate, 23 % had severe and 27 % had major injury according to the HISS system. Children had more severe injuries than adults. There was no significant difference regarding HISS or DASH scores between wedge and screw splitter injuries. The mean DASH score was 15, indicating moderate residual sequelae, but patients without sequelae and patients with grave sequelae were found in all HISS severity grades. There was a weak but significant correlation between the HISS and DASH scores. The mean Sollerman score in the injured hand was 66, indicating significantly impaired hand function. Twenty-nine percent of splitters were home-made. Very few machines had the safety measures required by European Standards. Children were present during splitting in at least 15 % of cases. Not being alone at the machine was one cause of wedge splitter injury. Glove use was one cause of screw splitter injury. Hand injury from powered wood splitters is a significant problem. Many of the injuries are severe, and cause long term sequels and impairment of hand function. Prevention is essential and should focus on unsafe machines and dangerous patterns of use.

Mastopexia com inclusão de implantes mamários após tratamento cirúrgico da obesidade mórbida: avaliação da satisfação das pacientes e resultados cirúrgicos / Mastopexy with breast implant inclusion after morbid obesity surgical treatment: patient satisfaction evaluation and surgical results

Cintra Junior, Wilson 24 February 2010 (has links)
INTRODUÇÃO: Pacientes portadoras de obesidade mórbida submetidas a tratamento cirúrgico através de cirurgias disabsortivas-restritivas, após considerável perda ponderal, evoluem com dobras cutâneas ou dermogordurosas em várias regiões do corpo. As mamas são caracterizadas pela deficiência de volume, ptose acentuada, assimetria e medialização dos complexos aréolo-papilares. A mastopexia com inclusão de implantes mamários tem demonstrado ser solução cirúrgica eficaz para melhora da forma, volume e simetria das mamas. OBJETIVO: Avaliar a satisfação das pacientes e os resultados cirúrgicos obtidos após a mastopexia com inclusão de implantes mamários. MÉTODOS: Vinte pacientes do sexo feminino, com média etária de 39,9 anos, foram submetidas à mastopexia com inclusão de implantes mamários entre setembro de 2008 e abril de 2009. Foram aplicadas entrevistas psicológicas semidirigidas a todas as pacientes, nos períodos pré e pós-operatórios, cujas respostas foram tabuladas, divididas em categorias, e possibilitaram a avaliação da satisfação das pacientes. Foi realizada avaliação dos resultados cirúrgicos através da análise fotográfica por três cirurgiões plásticos independentes, nos períodos pré e pós-operatórios, onde foram atribuídas notas zero, um ou dois, para os seguintes itens: forma da mama, volume da mama, simetria entre as mamas, posicionamento do complexo aréolo-papilar e qualidade e extensão das cicatrizes. RESULTADOS: Dezenove pacientes (95%) referiram satisfação com o resultado cirúrgico obtido (p<0,001). Quatro pacientes (20%) relataram melhora da vida profissional; doze pacientes (60%), melhora da vida social; dez pacientes (50%), da vida afetiva; e dez pacientes (50%), da vida sexual. A média das somatórias das notas atribuídas pelos três cirurgiões, referentes a cada paciente, variou entre 4,7 e 10, sendo a média geral de 7,28. Os resultados foram considerados bom ou ótimo para 65% da amostra e pobre para 8,4%. CONCLUSÕES: Houve satisfação de 95% das pacientes com os resultados obtidos pela mastopexia com inclusão de implantes. A análise fotográfica dos resultados obteve nota média de 7,28, caracterizado como bom resultado, apesar da fraca concordância entre os avaliadores. / INTRODUCTION: Morbid obesity patients submitted to surgical treatment through disabsortive-restrictive procedures, and after considerable weight loss, develop skin or fatty tissue folds in many regions of the body. These changes in the breasts, in particular, are characterized by volume deficiency, marked ptosis, asymmetry and medialization of the nipple-areola complexes (NAC). Mastopexy associated with breast implant inclusion has shown to be an efficient solution to improve shape, volume and breast symmetry. OBJECTIVE: To evaluate patient satisfaction and surgical results obtained after mastopexy with breast implant inclusion. METHODS: Twenty female patients with a mean age of 39.9 years were submitted to mastopexy with breast implant inclusion between September 2008 and April 2009. All patients had semi-directed psychological evaluation in the pre- and postoperative periods. The answers to the evaluations were tabulated, categorized, and allowed patient satisfaction analysis. The surgical results evaluation was made through photographic analysis of three independent plastic surgeons, in the pre- and post-operative periods, when scores of zero, one or two, were attributed to the following items: breast shape, breast volume, symmetry of breasts, NAC position, scar quality and extent. RESULTS: Nineteen patients (95%) referred satisfaction with the surgical results attained (p<0,001). Four patients (20%) referred improvement in their professional lives; twelve patients (60%), improvement in their social lives; ten patients (50%), of their affective lives; and ten (50%) of their sexual lives. The mean sum of the scores attributed by the three surgeons, respective to each patient, varied between 4.7 and 10, with an overall mean of 7.28. The results were considered good or great for 65% of the sample and poor for 8.4%. CONCLUSIONS: There was a 95% satisfaction rate among patients with the results obtained through Mastopexy with breast implant inclusion. The photographic analysis of the results obtained a mean score of 7.28, considered as a good result, albeit the weak correlation among evaluators.

"We are in Korea, everybody is ready to change": Etnografie plastické chirurgie v Korejské republice / "We are in Korea, everybody is ready to change": Ethnography of Plastic Surgery in the Republic of Korea

Mudruňková, Kateřina January 2015 (has links)
The purpose of this thesis is to identify practices that constitute plastic surgery in current Republic of Korea with emphasis put on relationships between participating human beings, materials and technologies. It focuses on practices proceeding inside and outside the clinic of plastic surgery. In accordance with M. Lock's concept of local biology this thesis introduces Korean plastic surgery as a set of practices shaped by mutual interaction of local technologies and Korean bodies. The actor network theory approach (ANT), which emphasizes relational open-ended forming of entities, is applied to examining various aspects of plastic surgery. This approach also provides new ways of exploring how the entities and practices described in the medical anthropology as medicalization, medical tourism or local biology are produced. Key words plastic surgery; Republic of Korea; Actor - Network Theory (ANT); bodily practices; local biology; beauty ideal; medicalization.

FENTES LABIO-PALATINES : Approche étiologique génétique. Place des gènes de l’angiogenèse. Développement d’un modèle d’étude in vivo chez l’enfant. / Cleft lip-palate : Genetic-etiologic approach and role of gene expression in angiogenesis. Development of an vivo study model in children.

Les fentes labio-palatines (FLP) sont la malformation cranio-faciale congénitale la plus fréquente. D'origine multifactorielle, elles sont la conséquence d'un défaut de fusion des bourgeons faciaux.Objectif et MéthodologieL'objectif de ce travail a été d'étudier la place des gènes de l'angiogenèse dans le cadre de la piste étiologique des FL/P. La méthodologie de ce travail comportait 3 étapes :- Une analyse systématique et exhaustive des gènes impliqués dans les FL/P comprenant les gènes identifiés mais aussi les gènes potentiellement impliqués.- Une analyse rétrospective des explorations génétiques des FL/P opérées au CHU de Reims entre 2003 et 2009.- La mise en place d'une analyse prospective (2009-2012, AOL) :- Génomique constitutionnelle par CGH Array- In situ au niveau des berges des fentes issues de déchets opératoires des chirurgies primaires des FL/P comprenant :Le développement d'un protocole de culture cellulaire de fibroblastesUne analyse anatomopathologiqueEt surtout le développement d'un modèle d'étude in vivo chez l'enfant d'analyse d'expression des gènes de l'angiogenèse.RésultatsL'analyse systématique des gènes impliqués dans les FL/P a mis en évidence 95 gènes dont plus d'une dizaine sont connus comme liés aux mécanismes d'angiogenèse (facteurs de croissance et protéases). Ces derniers sont en interaction entre eux mais aussi avec 18 autres gènes impliqués eux aussi dans les FL/P. Ainsi au total 1/3 des gènes d'intérêt sont soit des gènes de l'angiogenèse soit en lien avec eux.L'étude rétrospective nous a permis de mettre en exergue certaines formes cliniques originales qui ont été étudiées et publiées sous un angle « étiologique ».L'étude prospective nous a permis, après obtention des consentements, d'inclure 72 patients (30 FLP, 24FL, 18FP) opérés au CHU de Reims entre 2009 et 2012 d'une chirurgie primaire.Nous présentons :- nos résultats anatomopathologiques, et génétiques (CGH Array)- notre protocole de culture cellulaire- nos réflexions, notre cheminement aboutissant à la création du modèle d'étude d'analyse d'expression des gènes de l'angiogenèseDiscussionLa littérature a bien mis en avant une implication des phénomènes angiogéniques dans la constitution des FL/P par le biais des facteurs de croissance (TGFβ, PDGF C et Ra, FGF, TGFA, FGFR1, FGFR2 ; VEGF) et des protéases (MMP/TIMP2). L'ensemble de nos manipulations in situ nous permet aujourd'hui de disposer du matériel nécessaire pour l'étude de l'expression des facteurs impliqués dans l'angiogenèse sur les berges des fentes.Parallèlement, l'étude génomique constitutionnelle en CGH Array a permis de retrouver des variations non-connues comme polymorphiques chez 62% de nos patients. Des études familiales vont compléter notre travail. Elles permettront de savoir si ces CNV sont héritées ou De Novo et ainsi de préciser leur caractère bénin ou pathologique. L'identification chez un de nos patients d'une amplification, même de petite taille, du gène SKI (gène lié à la voie des TGFβ) nous encourage dans la poursuite de nos recherches d'anomalies constitutionnelles des gènes de l'angiogenèse dans les FL/PLa CGH array est une technique qui nous a paru particulièrement utile et fiable en terme de « scanning » et de dépistage.En conclusion, en pratique clinique, la découverte des anomalies préalablement certainement sous estimées par les cliniciens doit nous mener à une nouvelle réflexion sur le conseil génétique et sur l'utilité dans l'avenir d'un dépistage plus systématique. / Cleft lip and palate (CLP) are the most common congenital craniofacial malformation. They have a multifactorial etiology and are the consequence of incomplete fusion of the facial buds.Objective and MethodologyThe objective of this work was to study the role of the genes of angiogenesis in the framework of studying the etiology of CL/P. Our methodological approach included 3 steps:- Systematic and thorough analysis of the genes involved in CL/P including identified genes but also genes that could be potentially involved.- A retrospective analysis of the operated clefts at the University Hospital of Reims between 2003 and 2009.- Implementation of a prospective analysis (2009-2012, AOL):- Constitutional genomic study by CGH Array- In situ with tissue specimens extracted from surgically excised cleft edges including:The development of a protocol for fibroblast cell culturesHistopathological analysisAnd above all the development of an in vivo study model in children for analyzing the expression of genes of angiogenesis.ResultsThe systemic analysis of genes involved in cleft lip palate unveiled 95 genes including about ten that are known to be related to angiogenesis mechanisms (growth factor and proteases). These genes interact between themselves but also with 18 other genes also involved in CL/P. In all, 1/3 of relevant genes are either angiogenesis-related genes or in direct relation with them.The retrospective study permitted to underline the some original clinical forms that were studied and published under an « etiological » angle.The prospective study included 72 patients (30 CLP, 24CL, 18CP), for whom we obtained informed signed consents, operated at the University Hospital of Reims between 2009 and 2012 for primary cleft surgery.We present:- Our histopathological and genetic results (CGH Array)- Our cell culture protocol (submitted for publication)- Our approaches and thought process behind the design of a study model for analyzing expression profiling of angiogenic genesDiscussionThe literature has highlighted the role of angiogenesis in the formation of cleft lip/palate via growth factors (TGFβ, PDGF C and Ra, FGF, TGFA, FGFR1, FGFR2, VEGF) and proteases (MMP/TIMP2). All our manipulations in situ have yielded the necessary material, i.e. edges of resected clefts, to study the expression of factors involved in cleft angiogenesis.In parallel, the constitutional genomic study in CGH Array enabled to uncover abnormalities in 62% of our patients. Family studies will complete our work. They will help to refine if these CNV are inherited or de novo and thus indicate their benign or pathological nature. In one of our patients, the identification of the SKI gene (related to the TGFβ pathway) encourages us to continue our research of genetic abnormalities of angiogenic genes involved in cleft lip/palate. CGH array appeared to be a very useful and reliable method in terms of scanning and screening.In conclusion, in clinical practice, the discovery of abnormalities which were probably underestimated by clinicians before, leads us to rethink the issue of genetic counseling and the relevance of a more systematic screening for these abnormalities in the future.

"Estudo anatômico do retalho perfurante ântero-lateral da coxa" / Anatomic study of the anterolateral thigh flap

Ishida, Luiz Carlos 17 August 2006 (has links)
INTRODUÇÃO: O retalho ântero-lateral da coxa é baseado em vasos perfurantes do ramo descendente da artéria circunflexa lateral femoral. Este retalho tem características muito interessantes para a cirurgia reparadora, como a pequena espessura, pedículo longo e excelente área doadora. No entanto, existem muitas controvérsias na literatura quanto aos vasos perfurantes e ao trajeto do pedículo deste retalho. Neste trabalho procurou-se estabelecer alguns parâmetros anatômicos e esclarecer estas controvérsias. MÉTODO: Estudaram-se 100 coxas de 50 cadáveres quanto aos seguintes aspectos: 1- Número e localização de perfurantes encontrados, 2- Trajeto do pedículo perfurante, 3- Trajetória intramuscular, 4- Comprimento do trajeto intramuscular, 5- Comprimento total do pedículo, 6- Diâmetro dos vasos e 7- Espessura do retalho. RESULTADOS: 1- Encontraram-se de 0 a 4 perfurantes por coxa estudada, todas em um raio de até 6cm do ponto médio entre a espinha ilíaca ântero-superior e a borda lateral da patela. 2- Os vasos perfurantes tinham trajeto músculo-cutâneo em 75,76% das coxas e septo-cutâneo em 24,24%. 3- Dos pedículos perfurantes com trajeto músculo-cutâneo, 86,67% possuíam trajetória indireta contra 13,33% com trajetória direta. 4- O comprimento médio do trajeto intramuscular dos pedículos foi de 3,67 ± 2,01 cm. 5- O comprimento médio do pedículo total foi de 11,31 ± 3,12 cm. 6- O diâmetro médio da artéria na origem do ramo descendente da artéria circunflexa femoral foi de 2,21 ± 0,85 mm e para as veias no mesmo local de 2,66 ± 1,33 mm e 2,10 ± 1,11 mm. 7- A espessura da tela subcutânea foi de 8,98 ±6,23 mm e da pele de 1,60 ± 0,76 mm. CONCLUSÕES: 1- Existiu uma pequena possibilidade de não haver pedículos perfurantes. 2- Quando presentes, os pedículos perfurantes do ramo descendente da artéria circunflexa lateral femoral eram encontrados em numero de 1 a 4, sempre em um raio de 6 cm a partir do ponto médio entre a espinha ilíaca ântero-superior e a borda lateral da patela. 3- Os trajetos dos pedículos perfurantes eram predominantemente músculo-cutâneos. 4- A trajetória intramuscular encontrada foi predominantemente indireta. 5- O comprimento do trajeto intramuscular correspondeu a 31,69% do comprimento total do pedículo. 6- O comprimento total do pedículo se mostrou adequado tanto para transferências locais como à distancia por técnicas microcirúrgicas. 7- Os diâmetros dos vasos, tanto da artéria quanto das veias, se mostraram adequados para a realização de anastomoses microcirúrgicas. 8- A espessura do retalho encontrada foi significantemente maior nas coxas de indivíduos femininos, mas tanto nos homens quanto nas mulheres a espessura foi relativamente fina. / INTRODUCTION: The anterolateral thigh flap is based on the perforator vessels of the descending branch of the lateral circumflex femoral artery. This flap has very interesting characteristics for the reconstructive surgery, like the small thickness, long pedicle and excellent donor site. On the other hand, there are many controversial data on the literature about the perforator vessels and the pedicle course of this flap. The aims of this study are to establish some anatomical parameters and clear some controversies. METHOD: A hundred thighs of 50 cadavers were studied for: 1- The number and location of the perforator vessels. 2- The course of the perforator pedicles. 3- The intramuscular course. 4- The length of the intramuscular course. 5- The total length of the vascular pedicle. 6- The diameter of the vessels. and 7- The thickness of the flap. RESULTS: 1- There were found from 0 to 4 perforators per thigh, all in a 6cm radius from the mid point between the anterosuperior iliac spine and the lateral border of the patella. 2- The pedicles was musculocutaneous in 75,76% of the thighs and septocutaneous in 24,24%. 3- Among the musculocutaneous pedicles, 86,67% had a direct intramuscular course, and 13,33% had indirect course. 4- The mean length of the intramuscular course was 3,67 ± 2,01 cm. 5- The mean total pedicle length was 11,31 ± 3,12 cm. 6-The mean artery diameter on the origin of the descending branch of the lateral circumflex femoral artery was 2,21 ± 0,85 mm and the mean vein diameter on the same spot was 2,66 ±1,33 mm and 2,10 ± 1,11 mm. 7- The mean subcutaneous fat tissue thickness was 8,98 ± 6,23 mm and the mean skin thickness was e 1,60 ± 0,76 mm. CONCLUSIONS: 1- There was a possibility of finding no perforators of the descending branch of the lateral circumflex femoral artery. 2- When present, the perforators pedicles were found in numbers between 1 to 4, always in a 6cm radius from the mid point between the anterosuperior iliac spine and the lateral border of the patella. 3- The perforators pedicles courses were predominantly musculocutaneous. 4- The intramuscular courses were mainly indirect. 5- The intramuscular length was responsible for 31,69% of the total length of the vascular pedicle. 6- The total length of the pedicle was adequate for either local or microsurgical transfers. 7- The arterial and venous diameters were adequate for microsurgical anastomosis. 8- The female cadavers had significantly thicker flaps, but both in the male and the female cadavers the flap was considerably thin.
