Effects of the lower energy and pulse stacking in carbon dioxide laser skin treatment: an objective analysis using second harmonic generation.

PURPOSE: To evaluate the effect of fractional carbon dioxide (CO2) laser treatment using lower power associated with pulse stacking within collagen fibers, using second harmonic generation microscopy and computerized image analysis. METHODS: Twenty male Wistar rats aging eight weeks were used. Each treatment area received a single-pass CO2 fractional laser with different parameters. The 20 animals were divided into two groups and euthanized after 30 and 60 days. Second harmonic generation images were obtained and program ImageJ was utilized to evaluate the collagen organization within all areas. Collagen anisotropy, entropy and optical density were quantified. RESULTS: Increased anisotropy over time was observed in all four areas, but only reached statistical significance (p = 0.0305) when the mildest parameters were used (area four). Entropy decreased over time in all areas, but without significance(p = 0.1779) in area four. Density showed an overtime increase only in area four, but no statistical significance was reached (p = 0.6534). CONCLUSIONS: When combined, the results obtained in this study regarding anisotropy, entropy and density tend to demonstrate that it is possible to achieve collagen remodeling with the use of lower power levels associated with stacked pulses.

Comparative clinical evaluation of breast augmentation using silicone foam coated implants and textured implants.

PURPOSE: To evaluate whether silicone foam implants have a different evolution pattern compared to conventional texture implants. METHODS: Fifty-eight female patients underwent surgery. They were divided into two groups (silicone foam - Lifesil® - and microtexturized silicone - Lifesil®). The evolution was analyzed in postoperative consultations, with physical examination, photographic documentation and filling in a satisfaction questionnaire, in the postoperative period of one month, four months, one year and then annually, up to a maximum of 3 years of follow-up. RESULTS: There were no statistically significant differences in presence of rippling, stretch marks, breast ptosis, capsular contracture and quality of scars. There was a higher rate of patients who were very satisfied with the outcome 360 days after surgery in the group receiving silicone foam implants (p = 0.036). CONCLUSION: In short time, silicone foam envelope implants proved to be as reliable as textured silicone envelope implants, making them an option for augmentation mammoplasty.

Patient Versus Surgeon Preferences Between Traditional and Neo-omphaloplasty in Post-bariatric Abdominoplasty.

BACKGROUND: Abdominoplasty procedures have been proven highly valuable in promoting better quality of life for post-bariatric surgery patients. The literature reveals that the aspect of the navel is one of the most problematic issues regarding surgical results and many different surgical techniques have been proposed to obtain a satisfactory outcome. However, little is known about patients' preferences regarding these different techniques and their results. The aim of the present study was to compare evaluations made by plastic surgeons and patients of the results of two different techniques-traditional omphaloplasty and neo-omphaloplasty with lateral flaps. METHODS: Five plastic surgeons analyzed postoperative pictures of 54 post-bariatric abdominoplasties performed between 2008 and 2013 at the Unicamp Hospital. Pictures of 12 cases were selected and evaluated by 50 patients waiting for a post-bariatric abdominoplasty. A standardized scale was used that contained the following criteria: volume of the abdomen, lateral contour, quality of the scars, umbilicus and skin excess/flaccidity. RESULTS: Surgeons gave the highest scores to 71.6% of neo-omphaloplasty cases and patients to 43.7%. Both surgeons and patients graded navels operated on using this technique higher, although the comparison was not statistically significant for patient evaluations (p = 0.062). The navel aspect was considered the fourth most relevant aspect among those evaluated. CONCLUSION: Neo-omphaloplasty results were considered better than traditional omphaloplasty for surgeons and patients, although there was not a clear differentiation of results by the latter. The navel postoperative aspect was considered secondarily important by patients to the results of post-bariatric abdominoplasties.

Guided Surgery in Esthetic Region.

The placement of dental implants and subsequent placement of immediate temporary dentures after extractions has become a treatment modality accepted by the scientific community. In addition to the functional factor, the surgical procedure in a single stage in the anterior region of the maxilla offers an esthetic appearance, and relieves the psychological concerns of patients. To guarantee the success and longevity of treatments performed, the fabrication of surgical guides is a helpful method in these situations. Guided surgery has gained attention because it restores esthetics with immediate restoration, provides the patient with comfort in addition to dispensing with the need for performing surgical flaps. This auxiliary method allows the position and design of the implant, as well as the perforation sequence to be programmed, thus optimizing the clinical results. In this study, the authors present a clinical case of a patient who was submitted to extraction and subsequent implant placement with immediate loading in the anterior region of the maxilla, performed in a satisfactory manner.

Desenvolvimento e aplicação de um protocolo antropométrico para a avaliação de resultados de otoplastia / Development and implementation of an anthropometric protocol to evaluate results of otoplasty

INTRODUÇÃO: A proeminência dos pavilhões auriculares é a forma mais comum de deformidade desta estrutura, afetando em torno de 5% da população. A maioria dos trabalhos acerca da cirurgia de otoplastia apresenta avaliações subjetivas, não permitindo apreciar acuradamente os resultados no pós-operatório, bem como dificultando a comparação entre técnicas. Propõe-se o desenvolvimento e aplicação de protocolo específico para avaliação dos resultados. MÉTODO: Avaliação prospectiva pelo período de um ano de pacientes submetidos à otoplastia bilateral utilizando técnica baseada em modelagem cartilaginosa com suturas, utilizando medidas da distância hélice-mastoide em pontos padronizados. RESULTADOS: Foram operados 23 pacientes com idade média de 17,8 anos. A incidência de reoperação foi de 21,7% dos pacientes ou 10,7% das orelhas. Houve perda de cerca de 45% da correção obtida no ponto superior e 35% nos pontos médio e inferior nos pacientes não reoperados. CONCLUSÕES: O protocolo foi de fácil utilização e permitiu a avaliação objetiva tanto da deformidade no pré-operatório quanto dos resultados cirúrgicos. A técnica utilizada produziu resultados considerados adequados e comparáveis aos da literatura.

INTRODUCTION: Prominence is the most common deformity of the ear, affecting about 5% of the population. Most reports on otoplasty describe subjective evaluations, and do not provide accurate postoperative assessment or a comparison between techniques. We propose the development and implementation of a specific protocol to evaluate results. METHOD: A prospective evaluation for a period of one year in patients who underwent bilateral otoplasty was performed, using a technique based on modeling of the cartilage with sutures, and helix-to-mastoid distance measurements at standardized points. RESULTS: A total of 23 patients with an average age of 17.8 years underwent surgery. Reoperation was performed in 21.7% of the patients or 10.7% of the ears. Nearly 45% of the correction obtained at the upper point and 35% at the middle and lower points were lost in patients who did not undergo reoperation. CONCLUSIONS: The protocol was easily used and allowed objective evaluation of the preoperative deformity and surgical results. This technique produced results considered adequate and comparable to the literature.

Lower energy and pulse stacking. A safer alternative for skin tightening using fractional CO2 laser.

PURPOSE: To evaluate the effect of different energies and stacking in skin shrinkage. METHODS: Three decreasing settings of a fractional CO2 laser were applied to the abdomen of Twenty five Wistar rats divided into three groups. Group I (n=5) was histologically evaluated for microthermal zones dimensions. Groups II and III (n=10 each) were macroscopic evaluated with freeware ImageJ for area contraction immediately and after 30 and 60 days. RESULTS: No statistical significance was found within microthermal zone histological dimensions (Group I) in all settings studied. (Ablation depth: 76.90 to 97.18µm; Coagulation depth: 186.01 to 219.84 µm). In Group II, macroscopic evaluation showed that all settings cause significant immediate skin contraction. The highest setting cause significant more intense tightening effect initially, contracting skin area from 258.65 to 179.09 mm2. The same pattern was observed in Group III. At 30 and 60 days, the lowest setting significantly sustained contraction. CONCLUSION: Lower fractional CO2 laser energies associated to pulse stacking could cause consistent and long lasting tissue contraction in rats.

Lesöes traumáticas do cólon: sutura primária ou colostomia? / Traumatic injuries of the colon: primary suture or colostomy?

Analisa-se prospectivamente a indicaçäo de colostomias nas lesöes traumáticas do cólon, em funçäo do comprometimento anatômico, do tempo decorrido e de fatores de risco adicionais. No período de Janeiro de 1981 a Junho de 1986 foram operados 75 pacientes com traumatismos de cólon: 39 por arma de fogo, 29 por arma branca e sete por contusöes. As colostomia foram indicadas em 47 pacientes que apresentavam as lesöes mais graves, sendo os demais 28 pacientes tratados com sutura primária. Ocorreram 21 complicaçöes infecciosas, que se relacionaram ao intervalo pré-operatório > 10h; a uma gravidade de lesäo do cólon (GLC) graus III a V; a transfusöes > 2500 ml; a presença de colostomias; e ao índice de trauma abdominal (ITA) . 25. Cinco óbitos decorreram de complicaçöes infecciosas (p < 0,05), tendo-se verificado em casos com as lesöes de maior gravidade. Estes dados sugerem que nas lesöes agudas do cólon (<6h), a colostomia estará justificada quando a GLC estiver entre III e V, o ITA for > 25, ou o paciente se encontrar hemodinamicamente instável

Valor de um índice prognóstico anotômico na classificaçäo de pacientes traumatizados com lesöes abdominais e extra-abdominais / Value of an anatomical prognositic index in the classification of trauma patients with abdominal and extra-abdominal injuries

O trauma representa a maior causa de morte abaixo dos 40 anos, nos países industrializados, e sua avaliaçäo e tratamento apresentam evidente interesse prático. Tendo como objetivo a aplicaçäo do Penetrating Agdominal Trauma Index (PATI), descrito por Moore e col., ao lado de outras observaçöes clínicas e evolutivas, no estudo de casos com traumatismos abdominais, estudo consecutivo foi realizado com 320 pacientes. A natureza do agente vulnerante, as perdas sanguíneas, a morbidade e a mortalidade foram também documentadas. A idade média da populaçäo foi de 29,3 ñ 11,5 anos, com predominância do sexo masculino (286:34). O volume transfundido médio foi de 1.173 ñ 2.124ml e a duraçäo da hospitalizaçäo atingiu 10,3 ñ 11,6 dias. Os seguintes agentes traumáticos foram identificados: ferimentos por arma branca (142/320), agressöes por arma de fogo (94/320) e contusöes (84/320). A mortalidade alcançou 10,3% (33/320). O índice de Moore e col situou-se em média em 12,9 + 12,0 e previu corretamente o risco de mortalidade (p <0,0001). Também os casos necessitando de mais de 3.500ml de transfusöes exibiram significativa mortalidade (p <0,001>, näo tendo havido óbitos entre os casos näo transfundidos (n = 128). A mortalidade dos pacientes vítimas de armas brancas foi significativamente menor que a dos demais grupos considerados (p <0,005). Conclui-se que o PATI exibiu excelente valor prognóstico nesta experiência, recomendando-se seu uso rotineiro na avaliaçäo de casos com traumatismos abdominais
