Is professional recognition in plastic surgery related to activity in research

OBJECTIVE: To evaluate the relation of medical research, with the participation of prominent plastic surgeon in Congress.METHODS: We reviewed the scientific programs of the last 3 Brazilian Congress of Surgery, were selected 21 Brazilian plástic surgeons invited to serve as panelists or speakers in roundtable sessions in the last 3 congresses (Group 1). We randomly selected and paired by other members (associates) of the Brazilian Society of Plastic Surgery, with no participation in congress as speaker (Group 2). We conducted a search for articles published in journals indexed in Medline, Lilacs and SciELO for all doctors selected during the entire academic career and the last 5 years from March 2007 until March 2012. We assessed the research activity through the simple counting of the number of publications in indexed journals for each professional. The number of publications groups was compared.RESULTS: articles produced throughout career: Group 1- 639 articles (average of 30.42 items each). Group 2- 79 articles (mean 3.95 articles each). Difference between medias: p <0.001.CONCLUSION: The results demonstrate that the Brazilian Society of Plastic Surgery seeking professionals with a greater number of publications and journals of higher impact. This approach encourages new members to pursue a higher qualification, and give security to congressmen, they can rely on the existence of a technical criterion in the choice of speakers.

Plastic surgery in chest wall reconstruction: relevant aspects - case series

Objective: to discuss the participation of Plastic Surgery in the reconstruction of the chest wall, highlighting relevant aspects of interdisciplinaryness. Methods: we analyzed charts from 20 patients who underwent extensive resection of the thoracic integument, between 2000 and 2014, recording the indication of resection, the extent and depth of the raw areas, types of reconstructions performed and complications. Results: among the 20 patients, averaging 55 years old, five were males and 15 females. They resections were: one squamous cell carcinoma, two basal cell carcinomas, five chondrosarcomas and 12 breast tumors. The extent of the bloody areas ranged from 4x9 cm to 25x40 cm. In 12 patients the resection included the muscular plane. In the remaining eight, the tumor removal achieved a total wall thickness. For reconstruction we used: one muscular flap associated with skin grafting, nine flaps and ten regional fasciocutaneous flaps. Two patients undergoing reconstruction with fasciocutaneous flaps had partially suffering of the flap, solved with employment of a myocutaneous flap. The other patients displayed no complications with the techniques used, requiring only one surgery. Conclusion: the proper assessment of local tissues and flaps available for reconstruction, in addition to the successful integration of Plastic Surgery with the specialties involved in the treatment, enable extensive resections of the chest wall and reconstructions that provide patient recovery.

Effects of uterine cervix constriction on Wistar rats

PURPOSE: To verify if uterine cerclage can induce craniosynostosis or any cranial deformity in new born Wistar rats. METHODS: One pregnant female Wistar rat underwent laparotomy on day 18 of gestation and the uterus cervix was closed with a 3-0 nylon suture to avoid delivery, that occurs normally on the 21 day. The suture was released after 48 hours beyond the normal gestation period. The female rat delivered 11 pups. Six surviving rats from the delivery (group A - constrained group). Two rats were born from another mother and in the same age were used as control group (group B - 2 nonconstrained controls) were allowed to grow. They were sacrificed 1.2 years after their birth all the eight animals. Linear measurement, routine histology and computed tomography of the skull were performed at the time of their death to evaluate the cranial asymmetries by mesurements of the anatomical landmarks of the craniofacial skeleton of the rats on the two groups and compared then. RESULTS: We did not observe statistically significant differences in any of the compared measurements (p>0.05) obtained through the morphologic and radiologic methods. Histologic examinations did not reveal any sign of premature fusion or suture imbrications. Critical decrease in longitudinal body size was noticed as the limbs too in all the animals of group A. CONCLUSION: Constriction of uterine cervix leads to fetus suffering, even death for a few animals, associated to small body size, but not to craniosynostosis.

Long-Term Evaluation in Aesthetic Rhinoplasty in an Academic Referral Center

Plastic surgery is based on improving esthetic for the patient. In most services, the surgery outcome is evaluated in a subjective manner. Aim: to objectively assess the degree of patient satisfaction one year after rhinoplasty using the Rhinoplasty Outcome Evaluation questionnaire at a referral academic center. Materials and Methods: 69 patients operated in the otorhinolaryngology service were selected. The patients were operated upon by third year residents during the period from January to December 2007 and answered the questionnaire translated by the authors of this study. Results: we obtained a mean value of 73.25% of satisfaction for primary rhinoplasty and a mean value of 72.02% of satisfaction for secondary rhinoplasty. Conclusion: the level of satisfaction presented by the patients was considered to be very good.

A cirurgia reconstrutiva em patologia oncológica do nariz : paralisia do nervo facial anatomia cirurgia do nariz

RESUMO: Os carcinomas localizados no nariz são muito frequentes em todas as séries conhecidas. São de diagnóstico clínico fácil e a sua confirmação por biópsia é muito segura. As terapêuticas mais indicadas são a cirurgia e a radioterapia, genericamente eficazes. Verifica-se, no entanto, que os pacientes continuam a solicitar tratamento em estádios muito avançados, mesmo conhecendo o diagnóstico e tendo acesso aos serviços sem custos. Esta situação poderá explicar-se face ao curso relativamente lento de muitos destes tumores e à idade geralmente avançada dos doentes que, de acordo com alguns inquéritos, receiam mais a terapeûtica do que a doença. Para obtenção de informação útil para condução deste problema, foram ainda analisados outros parâmetros. A maioria dos pacientes continua a solicitar tratamento quando as lesões envolvem duas subunidades nasais. Esta circunstância permite planear o tratamento cirúrgico com relativa facilidade, isto é, com exérese e reconstrução cujo resultado estético final é bastante aceitável. Os tumores de grandes dimensões, envolvendo várias subunidades, sendo frequentes, raramente implicam rinectomia total. Pelo contrário, são mais frequentes os tumores que envolvem metade do nariz e as estruturas vizinhas tais como o maxilar, a órbita e o lábio superior, atingindo mesmo a base do crânio. O controlo da doença nestes estádios é muito difícil. Não raramente, quando se crê que a doença está controlada, a cirurgia reconstrutiva bem como outras formas de reabilitação conjugadas, deixam ainda muita insatisfação. A nossa actividade tem-se desenvolvido seguindo os critérios adoptados nos melhores centros, isto é, as técnicas clássicas, complementadas com refinamentos recentes. Porém reflectindo sobre os resultados obtidos no tratamento de tumores do nariz, surge-nos um conjunto de questões para as quais ainda não encontrámos respostas cabais. Actuando de acordo com os princípios que definem o estado da arte, não obtivemos ainda resultados que satisfaçam tanto os doentes quanto os cirurgiões. Incessantemente procuramos novos dados técnicos e científicos que nos permitam sair deste ciclo vicioso em que o doente retarda a procura de assistência, receoso de que a terapêutica o deixe desfigurado. Tendo sempre em vista a obtenção dos melhores resultados com o mínimo de tempos cirúrgicos, valorizamos alguns detalhes praticados nos retalhos com padrão vascular bem definido. Dado que as sequelas na zona dadora de tecidos são uma incontornável preocupação, procuramos refinar a sua aplicação no sentido de as atenuarmos. A fronte, excelente zona dadora para reconstrucção nasal major, era sede de sequelas actualmente inaceitáveis. Estudado o comportamento dos tecidos na fronte, depois de levantado o retalho e efectuado o seu encerramento com uso da técnica de expansão intra-operatória, determinámos a presença do Factor de Crescimento Vascular Endotelial no próprio retalho e na zona dadora, tendo em vista que a sua presença poderá explicar o comportamento dos tecidos que foram submetidos a esta técnica. Procurou-se estudar a qualidade da reconstrução em 45 pacientes submetidos a cirurgia de exérese e reconstrução nasal major, assim como a qualidade de vida, relacionada com a doença e a terapêutica. Embora se possa admitir a existência de dados sugestivos de estratégias mais adequadas, não foi possível relacionar a qualidade da reconstrução com qualidade de vida dos pacientes. Poderá eventualmente concluir-se que a observação permanente da reconstrução, com qualidade estética e funcional, será o melhor método de alterar a ideia clássica, ainda muito divulgada, mas já ultrapassada, de que a cirurgia reconstrutiva do nariz não é mais que transformar um defeito horroroso num defeito ridículo.---------------ABSTRACT: Malignant tumours found in the nose are very frequent in all known series. Clinical diagnosis is simple and confirmation of biopsy diagnosis is accessible and safe. The most advisable therapies are surgery and radiotherapy. Despite everything patients continue to wait until the tumour is in an advanced stage before asking for therapy, although they know the diagnosis and have free access to specialised services. This situation could probably be explained by the slow development rate of the tumours which is associated with the age of the patient. Upon inquiry, it was found that a significant number of patients are more afraid of therapy than of the disease itself. Other parameters have been analysed in order to obtain useful information about the management of this problem. The majority of patients seek adequate treatment when the lesions involve two nasal subunits. This allows the programming of surgical therapy with relative ease as they may be removed and reconstructed with interesting final aesthetical results. Large tumours involving several subunits are frequent, but they rarely call for total rhinectomy. On the contrary, tumours more frequently involve half of the nose and their neighbouring structures: for example, maxillary, orbital and upper lip, even reaching as far as the base of the skull. The control of the disease is very difficult in these stages.In cases in which it is believed that the disease is under control, reconstructive surgery in conjunction with other forms of rehabilitation still result in a lot of dissatisfaction. In our activity we try to follow the criteria adopted by the best centres following classic techniques, complemented with recent refinements. Reflecting on the treatment of tumours of the nose has led us to a series of questions to which we haven’t yet found the answers. In accordance with the defined principles of ‘the state of the art’ it still doesn’t satisfy either the patients or the surgeons. We are looking for new technical and scientific data which allows us to leave this vicious cycle, in that the deferred patient avoids looking for assistance, based on the fear that therapy could leave them disfigured. We attach importance to some practiced details on the well-defined vascular pattern of the flaps, with the principle aim of obtaining a good result, from the minimum number of operations. It is known that sequels in donor sites are a concern, so applied refinements are used in order to reduce the defect. The forehead has been considered an excellent donor site for major nasal reconstruction but the area of sequel is nowadays unacceptable. We tried to study the behaviour of the tissues of the forehead after taking the flap and closing the wound, using the intraoperative expansion technique. We determined the presence of Vascular Endothelial Growth Factor in the flaps and in the donor site, in which its presence could explain the behaviour of the tissues of the forehead that are submitted to this technique. The quality of the reconstruction was studied in 45 patients who were submitted to surgical exeresisand major nasal reconstruction, as was the relationship between the disease and the therapy regarding quality of life. It was not possible to directely relate the quality of the reconstruction to the quality of patients life, although some suggestive data of more adequate manegement may be interesting. One might eventually conclude that, permanent exposure of the reconstruction with aesthetic and funcional quality would be the best method in order to modify the classic idea which is still known although overridden today, that nasal reconstruction could transform a horrible defect into a ridiculous one.-------RÉSUMÉ: Les carcinomes situés sur le nez sont très fréquents dans toutes les séries connues. Ils sont de diagnostic facile et la confirmation de ce dernier par une biopsie, est accessible et très fiable. La chirurgie et la radiothérapie sont les thérapeutiques les mieux indiquées. Toutefois les patients continuent de solliciter un traitement, seulement dans des états très avancés bien qu’ils aient eu connaissance du diagnostic et ayant accès aux services. Cette situation pourra probablement s’expliquer par l’évolution relativement indolente de beaucoup de tumeurs, associée à l’âge des malades; bien que selon quelques enquêtes réalisées un nombre élevé de malades craint davantage la thérapeutique que la maladie. D’autres paramètres sont analysés en vue d’obtenir des informations utiles pour l’accompagnement de ce problème. La majorité de nos patients sollicite le traitement adéquat quand les lésions entourent deux sous-unités nasales, ce qui permet de planifier le traitement chirurgique avec une certaine facilité, c’est à dire l’exérèse et la reconstruction ayant un résultat final esthétique généralement très acceptable. Les tumeurs de grandes dimensions entourant différentes sous-unités sont fréquentes mais elles impliquent rarement une amputation nasal total. Au contraire, les tumeurs les plus fréquentes sont celles qui entourent la moitié du nez et les structures voisines comme le maxillaire, l’orbite et la lèvre supérieure, parfois, elles peuvent même atteindre la base du crâne. Le contrôle de la maladie dans ces états est très difficile et quand nous pensons que la maladie est contrôlée, la chirurgie reconstructrice associée à d’autres formes de réhabilitation provoquent encore une grande insatisfaction. Nous exerçons notre activité en essayant de suivre les critères adoptés dans les meilleurs centres. Nous appliquons les techniques classiques complétées de retouches pour obtenir un meilleur resultat. Le fait de traiter les tumeurs nasales nous fait réfléchir et poser un ensemble de questions auxquelles nous n’avons pas pu trouver de réponses. En actuant en accord avec les principes qui définissent l’état de l’art, nous n’avons pas obtenu de résultats qui satisfassent les malades et les chirurgiens. Nous recherchons de nouvelles données techniques et scientifiques qui nous permettent de sortir de ce cercle vicieux dans lequel le patient retarde la recherche d’aide craignant que la thérapeutique le défigure. Nous valorisons certains détails pratiqués sur les lambeaux de patron vasculaire bien défini et ayant comme principaux objectifs l’obtention d’un bon résultat en moins de temps de chirurgie. Nous savons que les séquelles de la zone donneuse de tissus sont préoccupantes, ainsi, que les retouches qui ont été appliqués dans l’objectif de les atténuer. Le front, excellente zone donneuse pour la reconstruction nasale majeure, était une source de séquelle actuellement inacceptable. Nous avons étudié le comportement des tissus du front après avoir relevé le lambeau et effectué la fermeture avec la technique de l’expansion intraoperative. Nous avons déterminé la présence du Facteur de Croissance Vasculaire Endothéliale dans le propre lambeau et dans la zone donneuse, celle-ci pourra expliquer le comportement des tissus du front qui ont été soumis à cette technique. On a essayé d´etudier la qualité de la reconstruction sur 45 patients soumis à la chirurgie d´exérèse et la reconstruction nasal majeure, ainsi comme la qualité de vie en relation avec la maladie et la thérapie. Quoique l´on puisse conclure par l´existence des données subjectives des stratégies plus justes, il est impossible de faire un rapport sur la qualité de la reconstruction avec la qualité de vie des patients. Eventuellement l´on purrait conclure que l´observation permanente de la reconstruction avec qualité esthétique et fonctionnelle, se serait la meilleure méthod de changer l´idée classique, mais depassée, de que la rhinopoièse n´est pas que transformer un affreux défaut par un défaut ridicule.

Cranioplasty: The autograft option

We present our clinical experience in cranioplasty with autograft as follows: conchal cartilage for losses up to 2 cm2, outer table grafts for defects up to 100 cm2, and, for larger defects still, split rib grafts, which may be combined with outer table grafts. We conclude that autograft is superior to alloplastic material in cranioplasty.

Undesirable effect of cosmetic lip augmentation with autologous fat tissue

Background: Facial cosmetic procedures are commonplace nowadays, especially techniques that aim to increase lip volume. Full lips provide a youthful, healthy, feminine and sensual appearance. There are many techniques and materials used to recover the loss of contour that occurs with age. Case presentation. An unusual case of fat tissue accumulation following cosmetic upper lip augmentation in a 61 year-old female was reported. Surgical treatment was performed for esthetic concerns. Microscopically, the tissue removed was composed of muscle fibers and mature adipocytes. Conclusion: Undesirable effects of esthetic treatment can occur and the clinician should be familiar with such complications to diagnose and manage them. © 2013 Kaminagakura et al.; licensee BioMed Central Ltd.

Open-Flap Versus Flapless Esthetic Crown Lengthening: 12-Month Clinical Outcomes of a Randomized Controlled Clinical Trial

Background: Excessive gingival display (EGD) has a negative impact on a pleasant smile. Minimally invasive therapeutic modalities have become the standard treatment in many dentistry fields. Therefore, the aim of this study is to compare the clinical outcomes of open-flap (OF) and minimally invasive flapless (FL) esthetic crown lengthening (ECL) for the treatment of EGD.Methods: A split-mouth randomized controlled trial was conducted in 28 patients presenting with EGD. Contralateral quadrants received ECL using OF or FL techniques. Clinical parameters were evaluated at baseline and 3, 6, and 12 months post-surgery. The local levels of receptor activator of nuclear factor-kappa B ligand (RANKL) and osteoprotegerin (OPG) were assessed by enzyme-linked immunosorbent assay at baseline and 3 months. Patients' perceptions regarding morbidity and esthetic appearance were also evaluated. Periodontal tissue dimensions were obtained by computed tomography at baseline and correlated with the changes in the gingival margin (GM).Results: Patients reported low morbidity and high satisfaction with esthetic appearance for both procedures (P > 0.05). RANKL and OPG concentrations were increased in the OF group at 3 months (P < 0.05). Probing depths were reduced for both groups at all time points, compared with baseline (P < 0.05). There were no differences between groups for GM reduction at any time point (P > 0.05).Conclusions: FL and OF surgeries produced stable and similar clinical results up to 12 months. FL ECL may be a predictable alternative approach for the treatment of EGD.

Evaluation of fecal microorganisms of children with cleft palate before and after palatoplasty

This study isolated and quantified intestinal bacteria of children with cleft palate before and after palatoplasty. A prospective study was conducted from May 2007 to September 2008 on 18 children with cleft palate, aged one to four years, of both genders, attending a tertiary cleft center in Brazil for palatoplasty, to analyze the effect of surgical palate repair on the concentration of anaerobes Bacteroides sp, Bifidobacterium sp and microaerophiles Lactobacillus sp in feces of infants with cleft palate before and 24 hours after treatment with cefazolin for palatoplasty. There was significant reduction of Lactobacillus sp (p < 0.002), Bacteroides sp (p < 0.001) and Bifidobacterium sp (p = 0.021) after palatoplasty, revealing that surgery and utilization of cefazolin significantly influenced the fecal microbiota comparing collections before and after surgery. However, due to study limitations, it was not possible to conclude that other isolated factors, such as surgical stress, anesthetics and other medications used in palatoplasty might have a significant influence on the microbiota. Considering the important participation of the intestinal microbiota on both local and systemic metabolic and immunological activities of the host, professionals should be attentive to the possible influence of these changes in patients submitted to cleft repair.

Chin augmentation with conchal cartilage

Profile enhancement most frequently involves mentoplasty. For this purpose, the author performs conchal grafts to the chin. A total of 28 women aged 15 to 76 years (mean age, 38.11 ± 15.11 years) requested mentoplasty by itself or combined with rhinoplasty, rhytidoplasty, or submental lipoplasty. The conchal cartilage was harvested subperichondrally through a posterior 3-cm incision. The specimen measured 3 x 1 cm, which was sufficient to project the chin 2 to 3 mm. For 4 to 5 mm of projection, both cartilages were used. The graft was positioned under the periosteum and held with two 5-0 nylon sutures. In these cases, the conchal cartilage graft was a suitable option for chin augmentations up to 5 mm.

Utilização do questionário ERG na avaliação do grau de satisfação dos pacientes submetidos à otoplastia em um serviço de residência médica de otorrinolaringologia

A importância da intervenção cirúrgica em diminuir o sofrimento psicológico e melhorar a autoestima em pacientes com deformidades auriculares já está bem documentada. As pesquisas têm focado nos resultados das terapias com ênfase no paciente, observando principalmente satisfação, resultado funcional e impacto na qualidade de vida. Quantificar alterações na qualidade de vida tem sido um desafio. O uso de inquéritos válidos, a exemplo da Escala de Resultados de Glasgow (ERG), auxiliam na obtenção dos dados. OBJETIVO: Avaliar o impacto na qualidade de vida dos pacientes submetidos à otoplastia realizada em serviço de residência médica, utilizando como base a ERG, bem como sua funcionalidade. CASUÍSTICA E MÉTODOS: Estudo retrospectivo incluindo pacientes submetidos à otoplastia entre julho de 2009 e julho de 2010. Os dados foram coletados por meio de questionário oferecido ao paciente no retorno pós-operatório. RESULTADOS: Trinta e seis pacientes responderam ao questionário. Houve aumento na qualidade de vida, demonstrado pelas medianas positivas obtidas pelo questionário. Não houve diferença significativa quanto aos valores obtidos entre os sexos e entre diferentes faixas etárias. CONCLUSÃO: Os pacientes mostraram-se satisfeitos com o resultado pós-operatório. Houve aumento de qualidade de vida, conforme demonstrado pelos resultados positivos. A ERG pareceu-nos fácil e elucidativa.

Forecasting the need for medical specialists in Spain: application of a system dynamics model

[EN] Background: Spain has gone from a surplus to a shortage of medical doctors in very few years. Medium and long-term planning for health professionals has become a high priority for health authorities. Methods: We created a supply and demand/need simulation model for 43 medical specialties using system dynamics. The model includes demographic, education and labour market variables. Several scenarios were defined. Variables controllable by health planners can be set as parameters to simulate different scenarios. The model calculates the supply and the deficit or surplus. Experts set the ratio of specialists needed per 1000 inhabitants with a Delphi method. Results: In the scenario of the baseline model with moderate population growth, the deficit of medical specialists will grow from 2% at present (2800 specialists) to 14.3% in 2025 (almost 21 000). The specialties with the greatest medium-term shortages are Anesthesiology, Orthopedic and Traumatic Surgery, Pediatric Surgery, Plastic Aesthetic and Reparatory Surgery, Family and Community Medicine, Pediatrics, Radiology, and Urology. Conclusions: The model suggests the need to increase the number of students admitted to medical school. Training itineraries should be redesigned to facilitate mobility among specialties. In the meantime, the need to make more flexible the supply in the short term is being filled by the immigration of physicians from new members of the European Union and from Latin America.
