Objetivo:avaliar resultados e satisfação dos pais quanto ao tratamento de crianças portadoras de sindactilia operadas entre 2005 e 2009 no Hospital SOS Mão Recife.Métodos:foram coletados, nos prontuários, os dados para avaliação dos resultados. Os escores subjetivos, verificados prospectivamente, foram: igual ou superior a 9, bom resultado; entre 6 e 8, resultado regular; abaixo de 6, mau resultado. Os resultados foram analisados estatisticamente. A pesquisa foi aprovada pelo Comitê de Ética da Instituição.Resultados:dos 35 casos, 21 (60%) foram sindactilias simples e 14 (40%) complexas; 22 (62,8%) eram meninos e 13 (37,1%) meninas. Houve predominância masculina nos casos complexos. As principais complicações foram: infecção (11,4%), sangramento (11,4%) e dor (8,6%). Ocorreram mais complicações nos casos complexos (42,8%) contra 33,3% nos simples. A avaliação subjetiva dos pais revelou: quanto à estética, média de 7,6, porém com média de 7,7 nos casos simples e 7,3 nos complexos; na função, a média foi de 8,2, 8,6 e 7,6, respectivamente, nas simples e nas complexas; em relação ao grau de satisfação dos pais, 8,3 (geral), 8,6 e 8 respectivamente; sobre a possibilidade de os pais recomendarem a cirurgia a outros, 85,7% recomendariam, contra 14,3% contrários. Foi observada forte associação entre a avaliação objetiva do especialista e os escores atribuídos pelos pais (p < 0,05).Conclusão:os resultados cirúrgicos da sindactilia apresentam diferenças entre os tipos simples e complexo, apesar de o aspecto estético e a satisfação dos pais serem semelhantes.

Objective:to evaluate the results from and parents' satisfaction with treatment for children with syndactyly who were operated at the "SOS Hand Recife" hospital between 2005 and 2009.Methods:data for assessing the results were gathered from the patients' medical files. The subjective scores, which were ascertained prospectively, were as follows: greater than or equal to 9, good result; between 6 and 8, fair result; less than 6, poor result. The results were analyzed statistically. This study was approved by the institution's ethics committee.Results:among the 35 cases, 21 (60%) consisted of simple syndactyly and 14 (40%) were complex; 22 (62.8%) were boys and 13 (37.1%) were girls. The complex cases were predominantly among males. The main complications were infection (11.4%), bleeding (11.4%) and pain (8.6%). There were more complications in the complex cases (42.8%) than in the simple cases (33.3%). The mean scores from the parents' subjective evaluations were as follows: 7.6 for esthetics (7.7 in simple cases and 7.3 in complex cases; 8.2 for function (8.6 in simple cases and 7.6 in complex cases); 8.3 for the parents' general satisfaction level (8.6 in simple cases and 8.0 in complex cases); and 85.7% of the parents would recommend the surgery to others while 14.5% would not. A strong association was observed between the specialist's objective assessment and the scores given by the parents (p < 0.05).Conclusion:the surgical results from treating syndactyly presented differences between the simple and complex types, even though the parents' esthetic evaluations and satisfaction were similar.

OBJETIVO: Relatar a frequência das doenças congênitas da mão operadas em sistema de mutirão no SOS Mão de Recife entre 2005 e 2009. MÉTODOS: Foram coletadas as informações de 833 crianças e adolescentes examinados em oito missões. RESULTADOS: Entre os pacientes, 306 (36,7%) foram operados; 240 (78,4%) por malformações congênitas e 66 (21,6%) por lesões adquiridas. As malformações congênitas mais frequentes foram: sindactilia, 72 (30,0%) casos; polidactilia, 30 (12,5%) casos; polegar bífido, 19 (7,9%) casos; malformação complexa da mão, 14 (5,8%) casos; mão em fenda, 13 (5,4%) casos; dedo em gatilho, 12 (5,0%) casos; camptodactilia, 11 (4,6%) casos; e braquisindactilia, nove (3,7%) casos. As lesões adquiridas mais frequentes foram: lesões por trauma obstétrico, 26 (39,4%) casos; sequela de trauma de mão, 18 (27,3%) casos; sequela de paralisia cerebral, sete (10,6%) casos; sequela de choque elétrico, cinco (7,6%) casos; e sequela de queimadura, quatro (6,1%) casos. CONCLUSÃO: A nosologia das doenças de mão é similar a de grandes séries de cirurgias eletivas, particularmente no que diz respeito às deformidades congênitas. As frequências das lesões adquiridas parecem ser mais altas do que as das séries internacionais. O sistema de mutirão de cirurgia de mão é importante para diminuir a carência dessa atividade em instituições públicas e tem se mostrado muito eficiente. O êxito do projeto pode oferecer subsídio para o Sistema Único de Saúde admitir cirurgiões da mão em sistema de plantão ou sobreaviso nas unidades de emergência.

OBJECTIVE: To report the frequencies of congenital hand diseases in patients who underwent surgery in a provisional clinic as part of the Hand of Recife SOS- Recife, Pernambuco, from 2005 to 2009. METHODS: The information was collected from 833 children and adolescents cared for in eight missions. RESULTS: Among the patients, 306 (36.7%) underwent surgery; 240 (78.4%) for congenital malformation, and 66 (21.6%) for acquired lesions. The most frequent malformations were: syndactyly, 72 (30.0%) cases; polydactyly, 30 (12.5%) cases; bifid thumb, 19 (7.9%) cases; complex hand anomaly, 14 (5.8%) cases; cleft hand, 13 (5.4%) cases; trigger finger, 12 (5.0%) cases; camptodactyly, 11 (4.6%) cases; and brachysyndactyly, 9 (3.7%) cases. The most frequent acquired injuries were: obstetric brachial plexus paralysis, 26 (39.4%) cases; hand trauma sequelae, 18 (27.3%) cases; cerebral paralysis sequelae, 7 (10.6%) cases; electrical shock sequelae, 5 (7.6%) cases; and hand burn injury, 4 (6.1%) cases. CONCLUSION: The nosology of hand diseases is, as a whole, similar to the great series of elective hand surgeries, especially regarding congenital hand abnormalities. The frequencies of acquired hand lesions seem to be higher than in the international series. The provisional clinic hand surgery system is important in decreasing the need for this activity in public institutions, and it has been shown to be very effective. The good outcomes of the missions may offer support for The Brazilian Health System to enroll hand surgeons in the on-call system in the emergency units.

In the field of biomedical applications a special interest exists regarding the study of the physicochemical and mechanical behaviour of materials, with special focus on the electrochemical degradation of metal/ceramic interfaces. In fact, metal/ceramic interfaces may be present in several biomedical devices, ranging from external or implantable sensors, to dental implants. Diffusion bonding represents an important technique since, in opposition to other production technologies, such as active metal brazing, avoid the possible liberation of certain chemical components harmful to health. The aim of this work is to study the electrochemical degradation of the interface formed between commercially pure Ti and Al2O3 produced by diffusion bonding, in contact with a physiological solution. The present approach included the evaluation of the contribution of individual and pairs of interfacial layers on the global degradation processes. For this propose d.c. electrochemical techniques were used to monitor the open-circuit potential, and to perform potentiodynamic polarization and galvanic corrosion evaluation. Also, electrochemical impedance spectroscopy was used as a complementary technique of the corrosion behaviour of the interface. Chemical composition and morphology of samples and corrosion products were evaluated by SEM and EDS analysis. According to experimental results, two principal reaction layers were formed in the interface: TiAl and Ti3Al. The TiAl layer appears to be the responsible for the strong increase in corrosion rate of the interface.
