本研究採用結紮眼血管的方法誘發短暫性視網膜缺血，針對同缺血時間同存活時間化成年金黄地鼠中視網膜節細胞的存活和小型膠質細胞的激活。首先，我們的據顯示，和假缺血手術組相對應的存活時間比較，暫時性視網膜缺血10分鐘或30分鐘沒有導致視網膜節細胞的存活明顯下。暫時性視網膜缺血60分鐘再灌注後7天，視網膜節細胞的存活下至58%，14後為51%，28後為44%。暫時性視網膜缺血120分鐘之後再灌注7天，視網膜節細胞的存活急劇下，僅保22%，至14天，僅剩17%, 之後節細胞的死亡速減緩，至28天時，仍由18%存活。視網膜缺血10分鐘、30分鐘、60分鐘和120分鐘均引起大小型膠質細胞激活，激活在第七天達到頂峰，之後在14天和28天顯著並逐步下。相關性分析發現損傷後7天，視網膜節細胞的死亡和視網膜節細胞層中的小型膠質細胞存在緊密的相關性。 / 其次，我們首次證實缺血性預處僅有於提高視網膜節細胞對抗視網膜缺血/再灌注損傷，還對視神經斷後的視網膜節細胞同樣具有保護作用。結果顯示無是5分鐘還是10分鐘的缺血性預處，無是軸突橫斷術前1天還是前3天實施預處，都對視網膜節細胞有明顯的保護作用。在缺血性預處對抗神經橫斷損傷的實驗組, 的表達只表現在陽性細胞上的明顯優勢，但占全部存活細胞的百分比存在差；而缺血性預處對抗視網膜缺血再灌注損傷的實驗組，的陽性節細胞的無論還是存活百分比都存在差。在預處組和假處組的比較中， 的表達也只是陽性細胞上較多，占全部存活細胞的百分比存在差。在缺血性預處加視網膜缺血分鐘的實驗組中，我們測視網膜矢片中各層的厚。結果顯示，缺血性預處組中，視網膜的整體厚和節細胞層的厚都與正常組相當，而假處組中，這層的厚明顯減少。 / 進一步地，我們研究遠端缺血性後處對視網膜節細胞對抗視神經軸突橫斷術的保護作用。我們選用鉗夾右股動脈作為遠端缺血性後處的方法，鉗夾股動脈分鐘，之後放開，再鉗夾再放開，共個循環。結果顯示，軸突橫斷術后分鐘實施缺血性后處組，視網膜節細胞的存活較假處組明顯增加，包括術後天和天；軸突橫斷術后小時實施缺血性後處組，視網膜節細胞的存活只在術後天較假處組明顯較多，但在天的實驗組，者的差消失；軸突橫斷術小時實施缺血性後處組，視網膜節細胞的存活比假處組多。在缺血性後處的實驗中，視神經橫斷術后分鐘實施遠端缺血性後處的實驗組與假處組比較，的表達僅表現在陽性細胞上的明顯增加，而且占全部存活細胞的百分比也明顯增加。的表達與預處實驗組的結果相似，只存在上的優勢。 / 我们的實驗證明，缺血性預處在對抗視神經橫斷和視網膜缺血的損傷中，可以為節細胞提供有效的保護作用，遠端缺血性後處可以對抗視神經橫斷損傷提高節細胞的存活。陽性節細胞在三個同條件的實驗中，表現出同的結果，这可能暗示遠端缺血性後處對抗視神經橫斷術的損傷，節細胞的再生能較優，與遠端缺血性後處對抗視神經橫斷術的神經保護作用有一定關。的表達在三個實驗組中，處組與假處組比較，均只表現出陽性細胞上的優勢，占存活細胞的百分比就存在差，可能意味著與缺血性預處和後處的保護作用關係不大。 / Ligature of the ophthalmic vessels (LOV) was used as an animal model to study transient retinal ischemia/reperfusion in adult hamsters. Firstly, we quantified the loss of retinal ganglion cells (RGCs) and activation of microglia after10 min, 30 min, 60 min or 120 min retinal ischemia at 7, 14 and 28 days post-ischemia. The results showed that after 10-min or 30-min retinal ischemia, the number of RGCs had no significant decrease compared to sham LOV group at 7 days. In the retinal ischemia 60 min group, there were 58% of the RGCs population remained alive at 7 days, 51% at 14 days and 44% at 28 days post-ischemia, respectively. In the retinal ischemia 120 min group, the number of RGCs was reduced to 22% at 7 days and 17% at 14 days, but cell death slowed down from 14 to 28 days. Meanwhile, the number of microglia was increased sharply at 7 days and decreased gradually from 7 to 28 days. At the same time, it was found that the loss of RGCs and activation of microglia in the ganglion cell layer at 7 days post-insult existed strong positive correlation. / Secondly, the effects of ischemic preconditioning (IPC) were proved to promote RGCs survival after axotomy or retinal ischemia 120 min. It was presented firstly that a 5 or 10 min brief IPC which performed 1 or 3 days prior to axotomy enhanced the RGCs survival at 7 days and 14 days post-axotomy. The number of HSP27-positive RGCs was significantly higher in the IPC plus axotomy subgroup compared with the sham-operated subgroup, while the percentage of HSP27-positive RGCs did not show significant difference between subgroups. For the IPC plus retinal ischemia 60 min group, both the number and the percentage of HSP27-positive RGCs had no significant difference between IPC and sham-operated subgroups. The number of HSP70-positive RGCs exhibited significant difference but not the percentage in IPC plus axotomy or retinal ischemia 60 min experimental groups. The thicknesses of the whole retina and GCL were similar to the normal value in the IPC plus ischemia 60 min subgroup, while in the sham-operated subgroup, these two values decreased significantly. / Consequently, the effect of remote ischemic postconditioning (RIPostC) was also explored to promote RGCs survival after axotomy. Four cycles of 10 min occlusion and 10 min release of the right femoral artery were initiated on animals at 10 min, 6 h or 24 h after axotomy. In the10 min group, the effect of RIPostC on promoting RGCs survival was significant at both 7 and 14 days post-injury. In the 6 h group, the survival of RGCs was more in the RIPostC treatment subgroup at 7 days, while there was no significant difference at 14 days post-axotomy. In the 24 h group, RGC survival was not significantly different at 7 days post-axotomy. Both the number and the percentage of HSP27-positive RGCs were significantly higher in the RIPostC treatment subgroup. The results of the induction of HSP70 only showed a priority in absolute number of the HSP70-positive RGCs in the RIPostC treatment subgroup. / In summary, the effect of IPC has been proved that it could protect RGCs against axotomy and retinal ischemia/reperfusion injury, in addition, the application of RIPostC also protected RGCs from axotomy. The proportion of HSP27-positive RGCs increased significantly in the process of RIPostC against axotomy, which may clue that the ability of axonal regeneration is stronger which induced by the RIPostC intervention. The upregulation of HSP27 might play a role in the neuroprotection of the RIPostC against axotomy. The expression of HSP70 maybe plays a little role in the neuroprotection of the IPC and RIPostC. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Liu, Xia. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 182-196). / Electronic reproduction.

子宮切除術是最常進行的婦科手術之一，據統計，美國每年平均錄得約600,000宗進行子宮切除術的病例。全腹腔鏡子宮切除術為子宮切除術的一種，在手術中，病人的子宮將經由完全使用腹腔鏡的模式被摘除。 / 在普遍全腹腔鏡子宮切除術的流程中，名為舉宮器的手術儀器會被應用於手術中，以改變病人子宮的位置及方向。手術室內，除了負責為病人摘除子宮的醫生外，還需額外一名負責操作舉宮器的醫生在場，以促進手術的進行。於手術的過程中，為使摘除手術能更有效及順利地進行，這名醫生需以人手操作舉宮器以控制病人體內子宮的方位。一般而言，這項工作都是枯燥而疲憊的。然而，在負責進行摘除手術的醫生眼中，縱子宮的方位已被調整，其方位仍然未如理想的情況亦不屬罕見。 / 故此，一個能勝任代替醫生負責操作舉宮器的機械人助手將會是可行的解決方案之一。與此同時，機械人亦能將病人子宮方位的控制權交回負責進行摘除手術的醫生手中。 / 本論文提出一套以把醫生從操作舉宮器的工作中釋放為目標，並使子宮方位操作變得更準確及穩定的機械人系統。機械人系統由兩個部分構成，分別為一支一個自由度的電動舉宮器以及一台三個自由度的舉宮器方位操作機械人。 / 舉宮器方位操作機械人旨在模仿以往醫生操作舉宮器的動作，以負責把固定在它身上的舉宮器移動到及固定在指定的位置。舉宮器方位操作機械人共有三個關節，分別為旋轉關節、滑動關節以及線性關節。關節的佈置滿足特定的幾何約束以構成遠程運動中心，使機械人能把手術儀器從細小的開口（例如：子宮頸）中進行操作。本論文提出的舉宮器方位操作機械人備有配適器以兼容不同款式的舉宮器，例如市場上現存的舉宮器以及本論文提出的電動舉宮器，均可應用在本系統中。 / 本論文提出的電動舉宮器為系統中可選擇性的元件，它是個一自由度附帶可轉動末端的裝置，旨在延伸機械人系統末端執行器的可到達範圍。 / 本論文將論述這套機械人系統的設計，包括其機械設計與電子系統的部分、運動學與及工作空間。一台實驗用的樣機已被建造以作驗證設計之用。該樣機以醫學人體模型為對象的實驗結果亦會在本論文中提出。 / Hysterectomy is one of the most frequently performed gynecologic procedures. In average, around 600,000 cases are recorded annually in the United States. Total laparoscopic hysterectomy (TLH) is one of the approaches of performing hysterectomy in which uterus of a patient is removed from an entirely laparoscopic approach. / In ordinary TLH procedures, a surgical apparatus, uterus manipulator, used for changing the position and orientation of the patient’s uterus is involved. In the operating theatre, apart from the primary surgeon who is responsible for the removal of uterus, an assisting surgeon is also involved for operating the uterus manipulator. Throughout the surgery, she/he has to manipulate the patient’s uterus using the uterus manipulator manually to facilitate the removal procedure. This task is generally tiring and boring. In addition, it is also common that the manipulated position is not satisfactory from the primary surgeon’s point of view. / Thus, a robotic assistant which is capable of taking up the task of this assisting surgeon as well as allowing the primary surgeon to have full control on the position of the patient’s uterus may be one of the potential solutions. / In this thesis, a robotic system aiming at providing more precise and stable manipulating motion and freeing the assisting surgeon who is responsible for operating the uterus manipulator is presented. The presented robotic system is composed of two parts, a motorized uterus manipulator of one degree of freedom and a robotic uterus manipulator positioner of three degrees of freedom. / Objective of the uterus manipulator positioner presented is to imitate what is doing by the assisting surgeon when operating the uterus manipulator. It holds and manipulates the uterus manipulator attached to it. The uterus manipulator positioner is a robotic system consisted of three joints, a revolute joint, a sliding joint and a translational joint. Arrangement of the joints is forced to satisfy specific geometric constraints so that a remote center of motion (RCM) is created to allow manipulation through small openings such as the cervix. Adaptors are included to enable the use of different uterus manipulators. Existing uterus manipulators and the motorized uterus manipulator presented in this thesis can be adapted to the system. / The motorized uterus manipulator presented in this thesis is an optional element of the robotic system. It is a device of one degree of freedom with a movable tip aiming at enhancing the reaching capability of the end-effector of the robotic system. / In this thesis, design of the robotic system in both mechanical and electronic aspects is presented. Kinematics and workspace of the system is also discussed. To verify the design, a prototype is built. Finally, verification experiments with the prototype on manikin are provided. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Yip, Hiu Man. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves 96-98). / Electronic reproduction.

Objetivo: O impacto da experiência em laparoscopia nas habilidades de cirurgia robótica ainda não está claramente estabelecido. Nosso estudo tem como objetivo comparar habilidades básicas em cirurgia robótica, usando o simulador de realidade virtual dVTrainer ®, entre cirurgiões com experiência laparoscópica e residentes de cirurgia do primeiro ano. Métodos: Vinte cirurgiões com experiência em laparoscopia (grupo 1) e vinte residentes de cirurgia do primeiro ano (grupo 2) foram incluídos no estudo. Cada participante completou quatro tentativas dos exercícios Peg Board 2, Ring and Rail 1 e Suture Sponge 1 no dVTrainer ®. O desempenho foi avaliado utilizando um algoritmo de pontuação computadorizado incorporado ao simulador. As pontuações e as métricas foram comparadas entre os grupos 1 e 2, e entre a primeira tentativa e as demais Resultados: Os escores gerais para os exercícios Peg Board 2 (738,04 ± 267,83 vs 730,39 ± 225,31; p = 0,57), Ring and Rail 1 (919,03 ± 242,69 vs 965,84 ± 222,96; p = 0,13) e Suture Sponge 1 (563,62 ± 185,50 vs 560,99 ± 152,71; p = 0,67) não apresentaram diferença significativa entre os grupos 1 e 2. O grupo 1 apresentou melhores resultados na área de trabalho dos controles mestres nos exercícios Peg Board 2 e Ring and Rail 1. O grupo 2 apresentou melhores resultados na economia de movimentos nos exercícios Peg Board 2 e Ring and Rail 1 e na força excessiva dos instrumentos no exercício Ring and Rail 1. Nos dois grupos os escores gerais na terceira ou quarta tentativas foram significativamente melhores em comparação com a primeira. Conclusões: Não há diferença significativa nas habilidades básicas da cirurgia robótica entre cirurgiões com experiência laparoscópica e residentes de cirurgia sem experiência em laparoscopia. Algumas diferenças existem quando consideramos métricas específicas, mas essas diferenças não foram capazes de modificar os resultados finais. Podemos considerar que a experiência em laparoscopia pode não se constituir em requisito essencial na aprendizagem da cirurgia robótica. / Objective: The actual impact of laparoscopic experience on robotic skills is uncertain. This study aimed to compare basic robotic surgical skills using the virtual reality simulator dVTrainer ® between laparoscopically experienced surgeons and first-year surgical residents. Methods: Twenty laparoscopically experienced surgeons (group 1) and 20 first-year surgical residents (group 2) were included. Each participant completed four trials of the following tasks on the dV-Trainer®: Peg Board 2, Ring and Rail 1 and Suture Sponge 1. Performance was recorded using a computerized built-in scoring algorithm. Scores and metrics were compared between groups 1 and 2 and between the 1st and subsequent trials Results: The overall scores for Peg Board 2 (738.04 ± 267.83 vs 730.39 ± 225.31, p = 0.57), Ring and Rail 1 (919.03 ± 242.69 vs 965.84 ± 222.96, p = 0.13) and Suture Sponge 1 (563.62 ± 185.50 vs 560.99 ± 152.71, p = 0.67) did not differ significantly between groups 1 and 2. Group 1 had better results for master workspace range in Peg Board 2 and Ring and Rail 1. Group 2 had higher scores for economy of motion in Peg Board 2 and Ring and Rail 1 and for excessive instrument force in Ring and Rail 1. In both groups, the overall scores in the 3rd or 4th trials were significantly higher than those in the 1st trial. Conclusions: There is no significant difference in basic robotic surgical skills between laparoscopically experienced surgeons and laparoscopically naïve surgical residents. Some slight differences were observed in specific metrics, but these differences were not sufficient to change the final results. We may assume that laparoscopic experience should not be an essential step in the learning curve of robotic surgery.

Orientador: Cristina Maria Garcia de Lima Parada / Resumo: Introdução: Na literatura científica, estudos relacionam as cesáreas ao aumento do risco de morbimortalidade materna e infantil. Além dos possíveis desfechos negativos observados no período perinatal, a literatura tem apontado, também, efeitos deletérios na primeira infância para crianças nascidas por operação cesariana, tais como: desmame precoce, asma, alergia e alterações de crescimento. Porém, com exceção do aleitamento materno e da asma, há viés na maioria dos registros, visto que não há a devida discriminação entre os desfechos relacionados às cesáreas indicadas e as cesáreas eletivas. A tese a ser explorada diz respeito aos efeitos adversos da cesárea no período perinatal e primeiro ano de vida, quando realizada sem indicação precisa, tendo como hipótese: os desfechos da cesárea eletiva são negativos no período perinatal e no primeiro ano de vida quando comparados aos mesmo desfechos do parto vaginal. Objetivos específicos: três estudos foram desenvolvidos, sendo que o primeiro, tem por objetivo classificar os tipos de partos de acordo com três referências: Federação Brasileira das Associações de Ginecologia e Obstetrícia (FEBRASGO), Ministério da Saúde (Comissão Nacional de Incorporação de Tecnologia no Sistema Único de Saúde – CONITEC) e revisão de literatura especialmente conduzida para tal finalidade e comparar os desfechos perinatais e no primeiro ano de vida associados a essas classificações; o segundo objetiva verificar o efeito da cesárea eletiva sobre os desfe...

In addition to the possible negative outcomes observed in the perinatal period, the literature has also pointed out deleterious effects in early childhood for children born by cesarean section, such as early weaning, asthma, allergy and growth disorders. However, with the exception of breastfeeding and asthma, there are biases in most registries, since there is no proper discrimination between outcomes related to indicated cesarean sections and elective cesarean sections. The thesis to be explored concerns the adverse effects of cesarean section in the perinatal period and first year of life, when performed without precise indication, with the hypothesis: elective cesarean outcomes are negative in the perinatal period and in the first year of life when compared to vaginal delivery outcomes. Specific objectives: three studies were developed, the first of which aims to classify the types of deliveries according to three references: Brazilian Federation of Associations of Gynecology and Obstetrics (FEBRASGO), Ministry of Health (National Commission for the Incorporation of Unitary Health System - CONITEC) and literature review conducted for this purpose and to compare the perinatal outcomes and in the first year of life associated with these classifications; the second objective was to verify the effect of elective cesarean sectio...

Enquanto o papel dos enxertos cartilaginosos na reconstrução da lamela interna palpebral está bem estabelecido, o crescimento da conjuntiva sobre ele, proveniente de áreas adjacentes, necessita de comprovação mais aprofundada. Este estudo tem como objetivos analisar comparativamente, após a reconstrução palpebral inferior com enxertos de cartilagem auricular conchal com e sem pericôndrio, em ambas as pálpebras inferiores de coelhos, a presença de crescimento conjuntival sobre os enxertos, a área de epitelização conjuntival sobre eles, a integridade da estrutura corneana dos globos oculares em contato com os enxertos cartilaginosos e a presença de alterações das áreas dos enxertos de cartilagem com e sem pericôndrio, após sua implantação. Foram utilizados, para o experimento, 50 coelhos albinos adultos da raça New Zealand (Oryctolagus cuniculus), entre 3 e 4 meses de vida, com pesos médios variando de 2,5 a 3,0 quilogramas no início do experimento, provenientes do biotério da Faculdade de Medicina da Universidade de São Paulo. Cem pálpebras inferiores foram reconstruídas em sua lamela interna, com enxertos autógenos de cartilagem auricular conchal, e cobertos com retalho miocutâneo. As pálpebras do lado direito receberam enxerto de cartilagem com pericôndrio posicionado em contato direto com o globo ocular, enquanto as do lado esquerdo foram reconstruídas da mesma forma, porém com enxertos cartilaginosos sem pericôndrio. A cada semana, em um total de 5 semanas, eram sacrificados 10 animais após a reconstrução palpebral, e suas pálpebras inferiores foram analisadas macroscópica e histologicamente. A planimetria digital demonstrou que, com 5 semanas, a área média das cartilagens com pericôndrio apresentava redução de 8,33%, e a área média das cartilagens sem pericôndrio encontravase reduzida em 18,52%. Detectou-se, em cada semana de avaliação, que as áreas das cartilagens com pericôndrio se apresentaram significativamente maiores do que aquelas sem pericôndrio nas semanas 4 e 5 (p=0,0003 e p=0,0001, respectivamente), e uma tendência para significância na semana 2 (0,0706). Na primeira e terceira semanas, a diferença entre as áreas se manteve igual (p=0,8583 e p=0,2092). Em relação ao crescimento conjuntival, observouse que a diferença porcentual do crescimento sobre as cartilagens com e sem pericôndrio foi de 11,41% na primeira semana do experimento, de 13,64% na segunda semana, de 18,69% na terceira, de 10,38% na quarta, e de 6,17% na quinta. Observou-se, em cada semana do experimento, que a porcentagem média de crescimento da conjuntiva nas pálpebras reconstruídas com enxerto condro-pericondral apresentou-se significativamente maior do que aquelas apenas com enxerto cartilaginoso nas 5 semanas do experimento (p<0,0001). Observou-se que houve crescimento conjuntival sobre os enxertos de cartilagem em contato direto com o globo ocular, ocorrendo tanto nas cartilagens com pericôndrio, como naquelas que não o possuíam. A área de cobertura conjuntival com 5 semanas nas cartilagens com pericôndrio, foi maior do que a observada nas cartilagens sem pericôndrio. Não houve ceratite ou úlceras de córnea na maioria da amostra estudada e houve diminuição das áreas dos enxertos cartilaginosos em graus variados, com maior intensidade nos enxertos sem pericôndrio. / Although the role of cartilage grafts in reconstruction of the posterior eyelid lamella is well established, conjunctival epithelialization on such grafts has yet to be fully proven. The aim of this study is to perform a comparative analysis, after inferior eyelid reconstruction in rabbits with cartilage grafts with and without perichondrium, the presence of conjunctival epithelialization over conchal cartilage grafts, the area of conjunctival epithelialization over those grafts, the integrity of the corneal structure in contact with the cartilage grafts and the variation of the areas of the cartilage grafts with and without perichondrium. Fifty adult albino New Zealand rabbits (Oryctolagus cuniculus) between 3 and 4 months of age with average weights from 2.5 to 3.0 kilograms from the University of São Paulo Medical School animal colony were used for the experiment. The posterior lamellae of 100 lower eyelids from were reconstructed with autogenous grafts of conchal ear cartilage and covered with a myocutaneous flap. In the right eyelids, cartilage was grafted with the perichondrium in direct contact with the eyeball, while the left eyelids were reconstructed in a similar manner but using cartilage grafts without perichondrium. The animals were sacrificed after 1, 2, 3, 4 and 5 weeks after eyelid reconstruction, and their lower eyelids were analyzed macroscopically and histologically. The digital planimetry has demonstrated that in the first week of the experiment there was a reduction of 8,33%, in the average area of the cartilages with perichondrium and a reduction of 18,52% in the average area of the cartilages with perichondrium. The average areas of the cartilages with perichondrium were significantly larger than those on cartilages without perichondrium in weeks 4 and 5 (p=0,0003 and p=0,0001, respectively) and tended to vary over the week 2 (0,0706). No difference was noted between the areas in weeks 1 and 3 (p=0,8583 and p=0,2092). When the conjunctival growth was assessed, it was found that the percentage difference in conjunctival epithelialization on the cartilage with perichondrium and that without perichondrium was 11.41% in the first week of the experiment, 13.64% in the second week, 18.69% in the third, 10.38% in the fourth and 6.17% in the fifth. The average percentage conjunctival epithelialization in the eyelids reconstructed with a cartilage graft with perichondrium was significantly higher for the five weeks of the experiment than that in the eyelids reconstructed with cartilage without perichondrium (p<0.0001). It was found that there was conjunctival growth on the cartilage grafts with and without perichondrium when they were placed in direct contact with the eye. The area of the epithelialization on cartilages with perichondrium was larger than that on cartilages without perichondrium in week 5. Neither keratitis nor corneal ulcers were observed during the 5 weeks of the experiment in the majority of the animals operated on and there was reduction in the areas of the grafts in various degrees, with larger intensity in the grafts without perichondrium.

Introdução. O estudo procurou investigar a evolução pós-operatória (PO) mediata e tardia de pacientes que participaram de um estudo anterior, sendo submetidos à primeira cirurgia de revascularização do miocárdio (CRM), correção de valvopatias e cirurgias combinadas, entre agosto/2013 e fevereiro/2015. Objetivo. Identificar as principais complicações e a ocorrência de óbito no PO mediato e investigar a evolução tardia desses pacientes, dentro de dois anos, quanto aos locais de retorno, necessidade de novas internações e de procedimentos relacionados ao aparelho circulatório, presença de infecção de sítio cirúrgico (ISC) e desfecho ao término deste período. Método. Estudo observacional, tipo coorte retrospectiva. Coletouse os dados mediante consulta aos prontuários dos pacientes e ao sistema de intranet do hospital, de março/2016 a outubro/2017. No PO mediato investigou-se a presença de complicações por sistema e o desfecho da internação; no PO tardio investigou-se o local dos retornos ambulatoriais; reinternações e suas causas; novos procedimentos/condutas relacionados ao aparelho circulatório; presença de ISC e desfecho clínico após dois anos. Realizamos uma análise descritiva das variáveis do estudo. Resultados. A amostra foi composta por 118 pacientes, 59 (50%) submetidos à CRM, 48 (40,6%) às cirurgias para correção de valvopatias e 11 (9,4%) às cirurgias combinadas. A hiperglicemia foi a complicação mais frequente entre pacientes que realizaram a CRM (64,4%) e entre aqueles submetidos às cirurgias combinadas (45,5%). No grupo de pacientes que realizaram cirurgias para correção de valvopatias, a complicação mais frequente foi o distúrbio de coagulação (20,8%). Todos os pacientes da amostra tiveram alta hospitalar. Quanto ao seguimento PO inicial, todos os pacientes, independentemente da cirurgia realizada, tiveram pelo menos um retorno no hospital do estudo. Ao longo de dois anos após a alta, 25,4% dos pacientes submetidos à CRM foram reinternados, assim como 33,3% dos submetidos às cirurgias para correção de valvopatias e 18,2% dos submetidos às cirurgias combinadas. Dois pacientes do grupo de CRM foram submetidos à intervenção coronária percutânea (ICP) e apenas um do grupo de válvula foi submetido a uma nova cirurgia cardíaca no período do estudo. Quanto à ISC, no grupo de CRM, cinco pacientes apresentaram infecção na safenectomia, um evoluiu com endocardite e um com mediastinite; no grupo de valva, apenas um evoluiu com endocardite, daqueles submetidos às cirurgias combinadas, um apresentou infecção da ferida esternal e um mediastinite. A maioria dos pacientes encontrava-se vivo após dois anos da alta hospitalar (CRM = 96,6%; cirurgia de valva = 83,3% e cirurgia combinada = 90,9%). Conclusão. A frequência de complicações dos pacientes no PO mediato foi baixa, e todos tiveram alta hospitalar. Quanto à evolução PO tardia, a maioria dos pacientes permanecia em acompanhamento ambulatorial no hospital do estudo após dois anos da alta hospitalar. Entre os pacientes estudados, apenas um do grupo de cirurgias corretivas de valvopatias foi submetido a nova cirurgia cardíaca, e dois do grupo de CRM à ICP. Quanto à ISC, poucos a desenvolveram, a maioria dos quais pertencia ao grupo de CRM. A maioria deles, independentemente da cirurgia realizada, encontrava-se vivo após dois anos da alta hospitalar. / Introduction. This study aimed at investigating the medium and long-term postoperative (PO) evolution of patients who participated in a previous study, who were submitted to the first myocardium revascularization surgery (MRS), valvopathy correction and to combined surgeries, from August/2013 to February/2015. Objective. Identifying the main complications and cases of death among patients in the medium-term PO and investigate the late evolution of these patients, within two years, their return to the hospital, the need for other hospitalizations, the need for new procedures regarding their circulatory system, the presence of surgical site infections (SSI) and their outcome in this period. Method. Observational and retrospective cohort study. Data was collected from the records of patients and the intranet system of the hospital, from March/2016 to October/2017. In the medium-term PO, the complications in each system were investigated as was the outcome of the hospitalization; in the long-term PO, the site of outpatient returns; rehospitalizations and their motives; new procedures/conducts related to the circulatory system; the presence of SSI and the clinical outcome after two years. A descriptive analysis of the study variables was made. Results. The sample of the study included 118 patients, 59 (50%) had undergone MRS, 48 (40.6%) valvopathy correction surgeries and 11 (9.4%) combined surgeries. Hyperglycemia was the most common medium-term PO complication among patients who underwent the combined surgery (45.5%), while those who underwent valvopathy correction surgeries most commonly presented coagulation disorder (20.8%). All patients in the sample were discharged. Regarding the initial PO monitoring, all patients came back to the hospital at least once. Regarding the rehospitalizations in the first two years after the discharge from the first heart surgery, 25.4% of patients who underwent MRS were re-hospitalized, as were 33.3% of those who underwent valvopathy correction surgeries and 18.2% of those who underwent combined surgeries. Two patients from the MRS group were submitted to percutaneous coronary interventions (PCI) and only one in the group of corrective valvopathy was submitted to another surgery in the period of the study. Regarding the presence of SSI, in the SMR group, five patients had infections after saphenectomies, one had endocarditis and one, mediastinitis; considering valvopathy correction patients, one presented with endocarditis, while one of those who underwent combined surgeries had sternum injuries and another, mediastinitis. Most patients were alive two years after discharge (SMR=96.6%; valvopathy correction=83.3% and combined surgery=90.9%). Conclusion. The frequency of complications among patients in the medium-term PO was low, and all of them were discharged from the hospital. Regarding long-term PO evolution, most patients were undergoing outpatient monitoring in the hospital were the study was conducted two years after hospital discharge. Among all patients in the study, only one, in the group of valvopathy correction, underwent new cardiac surgeries, and two of the SMR group underwent PCI. Few patients presented SSI, and most were in the MRS group. Most patients were alive after two years.

Intensified consumption makes abstinence symptoms more probable to appear. The social factors that contributed to the experimentation become less motivating and the dependence happens to be controlled by the avoidance of the symptoms of the abstinence. The continued use of the cigarette causes changes in brain physiology that makes its cessation process something continuous and complex. Some triggers identified as abstinence-hindering refer to deficits in social skills. The term HS is used to designate learned behavioral capacities that involves social interactions. The present study was conducted from February to March 2017 and evaluated and correlated degree of nicotine dependence and social skills in sixty smokers patients hospitalized by vascular surgery team at a general hospital in the interior of the State of São Paulo, with the purpose of suggesting a therapeutic group where the deficits in social skills found in this study will be able to be work on. A descriptive type of search was performed. Participants were approached and invited to participate in the research whose data were analyzed quantitatively. Of the 60 participants, 23 were women and 37 were men, mean age was 62.85 years, with 52.51 years using cigarette. Only 18.33% tried to stop smoking and the beginning of use for them were at 10.33 years. Only 21.66% of the dependents did not have a smoker's family member, and 5% reported that their support group were non-smoker. According to the Fagerström test for nicotine, the majority of the evaluated patients have low and medium degree of dependence (adding up the two values). For social skills, the total scores for both genders correlate with the Fagerström test, which shows that the more dependent the more socially skilled, which may mean that the tobacco user feels socially skillful without being, if it is so, largely from a social skills training as part of the smoking cessation treatment. / O tabaco é uma das principais causas de morte prematura no mundo e sua dependência é mantida pela nicotina e determinada por processos biológicos, comportamentais, psicológicos e socioculturais. O consumo intensificado torna possível o surgimento dos sintomas de abstinência. Os fatores sociais que contribuíram para a experimentação passam a ser menos motivadores e a dependência passa a ser controlada pela evitação dos sintomas da abstinência. O uso contínuo do cigarro causa alterações na fisiologia cerebral que farão o processo de cessação do mesmo ser contínuo e complexo. Alguns gatilhos identificados como dificultadores da abstinência referem-se a déficits em habilidades sociais. O termo HS é utilizado para designar capacidades comportamentais aprendidas que envolvem interações sociais. O presente trabalho foi realizado de fevereiro à março de 2017 e avaliou e correlacionou grau de dependência de nicotina e habilidades sociais em sessenta pacientes tabagistas internados pela equipe de cirurgia vascular em um hospital geral do interior do Estado de São Paulo com o intuito de sugerir um grupo terapêutico para que os déficits em habilidades sociais encontrados sejam trabalhados posteriormente. Foi realizada uma pesquisa do tipo descritiva. Os participantes foram abordados e convidados a participar da pesquisa cujos dados obtidos foram analisados quantitativamente. Dos 60 participantes, 23 eram mulheres e 37 eram homens, de idade média de 62,85 anos, com 52,51 anos de uso de cigarro. Apenas 18,33% tentaram parar de fumar e o início do uso foi aos 10,33 anos. Apenas 21,66% dos dependentes não possuíam nenhum familiar também tabagista e 5% referiu que o grupo de apoio não era fumante. Segundo o teste Fagerström para Nicotina a maioria dos avaliados encontra-se com grau de dependência baixa e média (somando-se os dois valores). Quanto as habilidades sociais os escores totais para ambos os gêneros correlacionam -se com o teste de Fagerström, o que mostra que quanto mais dependente mais habilidoso socialmente, o que pode significar que o usuário do tabaco se sinta habilidoso socialmente sem o ser, beneficiando-se assim, largamente de um treino de habilidades sociais como parte do tratamento de cessação do tabagismo.

Introdução: As Infecções Relacionadas à Assistência á Saúde (IRAS) são consideradas um problema de saúde pública com implicações sociais e econômicas graves que geram sobrecarga nas instituições de saúde, aumentando o período de internação e elevando consideravelmente a morbimortalidade em pacientes hospitalizados. A infecção do sítio cirúrgico (ISC) se constitui como uma das mais temidas complicações decorrentes dos procedimentos cirúrgicos No Brasil, são escassos os estudos epidemiológicos sobre as infecções em pacientes submetidos à procedimentos anestésico cirúrgico. Objetivo: Identificar a prevalência de infecção de sítio cirúrgico em pacientes adultos submetidos à cirurgia num hospital geral privado filantrópico, de nível terciário do interior paulista, segundo o potencial de contaminação da ferida operatória. Materiais e Métodos: Trata-se de um estudo de corte transversal, com abordagem retrospectiva e quantitativa, aprovado pelo Comitê de Ética em Pesquisa da Escola de Enfermagem de Ribeirão Preto da Universidade de São Paulo. A população do estudo foi constituída 58 prontuários médicos de pacientes submetidos à cirurgia no referido hospital exceto nas especialidades de ortopedia e ginecologia, no período de janeiro de 2014 a dezembro de 2014 e que apresentaram infecção do sítio cirúrgico. Os dados foram coletados por meio de consulta aos prontuários e analisados por meio de estatística descritiva utilizando-se o programa Statistical Package for the Social Sciences, version 17.0 para Windows. Resultados: A taxa global de infecção do sítio cirúrgico foi de 1,9% (57/3.064), as especialidades com maiores taxas foram a neurocirurgia (3,5%), seguida pela cirurgia geral (2,0%). Ao se analisar a taxa de infecção por potencial de contaminação, nas cirurgias limpas foi de 1,0%, nas potencialmente contaminadas 1,8%, nas contaminadas 5,4% e nas infectadas 7,2%. Nas cirurgias limpas a maior taxa foi na neurocirurgia, na potencialmente contaminada foi na cirurgia torácica, na contaminada e infectada foi na cirurgia geral. E ressalta-se que 46,6% tiveram infecção de órgão ou cavidade. Conclusão: O presente estudo permitiu identificar as taxas globais de infecção do sítio cirúrgico e também, por especialidades e por potencial de contaminação, dados esses que podem contribuir para o planejamento das ações de prevenção e controle de Infecção do sítio cirúrgico no referido hospital / Introduction: Healthcare-associated infections (HAI) are considered to be a public health problem with serious social and economic implications that overload health institutions, extend hospital length of stay and considerably increase morbidity- mortality among hospitalized patients. Surgical site infections (SSI) are one of the most feared complications from surgical procedures. There are few epidemiological studies in Brazil on infections among patients submitted to anesthetic-surgical procedures. Objective: To identify the prevalence of surgical site infection among adult patients submitted to surgery in a tertiary philantropic private general hospital in the interior of the state of São Paulo, according to the potential of contamination of the operative wound. Materials and Methods: This is a cross-sectional study, using a retrospective and quantitative approach, approved by the Research Ethics Committee of the Ribeirão Preto College of Nursing, at the University of São Paulo. The study sample was made up of 58 medical records of patients submitted to surgery in this hospital, except for the orthopedics and gynecology specialties, from January to December 2014, who presented surgical site infection. Data were collected from the medical records and analyzed by means of descriptive statistics, using the Statistical Package for the Social Sciences software, version 17.0 for Windows. Results: Overall surgical site infection rate was 1.9% (57/3,064), and specialties with higher rates were neurosurgery (3.5%) and general surgery (2.0%). Regarding the infection rate by potential contamination, in clean surgeries it was 1.0%; in potentially contaminated surgeries, it was 1.8%; in contaminated surgeries, it was 5.4%; and in infected surgeries, it was 7.2%. Neurosurgery presented the highest rate in clean surgeries; thoracic surgery in potentially contaminated surgeries; whereas general surgery had the highest rate in contaminated and infected surgeries. It is worth highlighting that 46.6% reported organ or cavity infection. Conclusion: This study allowed to identify overall rates of surgical site infection, also by specialty and potential of contamination. These data can contribute to the planning of actions to prevent and control surgical site infection in the studied hospital

Introdução: A cirurgia de retalho faríngeo (CRF) é um procedimento indicado para o tratamento da insuficiência velofaríngea, cujo principal sintoma é a hipernasalidade. Para complementar os achados perceptivos dos resultados de fala da CRF são utilizados métodos instrumentais, como a nasometria e a técnica fluxo-pressão. Objetivos: Verificar os resultados de fala da cirurgia de retalho faríngeo comparando-se os três tipos de fissura labiopalatina mais incidentes: fissura de lábio e palato unilateral (FLPU), fissura de lábio e palato bilateral (FLPB) e fissura isolada de palato (FP). Material e Métodos: Estudo transversal, por meio da análise retrospectiva de registros pré e pós-operatórios quanto à avaliação nasométrica e aerodinâmica de 290 pacientes (73 FLPU, 105 FLPB e 112 FP) submetidos à CRF de pedículo superior. A nasalância (correlato acústico da nasalidade) é determinada durante a leitura de amostras de fala padronizadas, utilizando-se um nasômetro (Kay Elemetrics Corp.). Valores de nasalância superiores a 27% são considerados sugestivos de hipernasalidade. Na avaliação aerodinâmica, o fechamento velofaríngeo é estimado a partir da medida da área seccional velofaríngea (sistema PERCI-SARS), durante a produção do fone [p] inserido no vocábulo rampa, permitindo estimá-lo de acordo com a seguinte classificação: valores de 0 a 4,9 mm2=fechamento adequado, 5 a 9,9 mm2=adequado para marginal, 10 a 19,9 mm2=marginal para inadequado e 20 mm2=fechamento inadequado. O teste t pareado comparou os valores de nasalância pré e pós-operatórios em cada tipo de fissura labiopalatina. e os testes ANOVA e Tukey verificaram as diferenças entre os três tipos de fissuras labiopalatinas, nas condições pré e pós-operatória. A área velofaríngea pré e pós-operatória foi analisada por meio do teste de Wilcoxon, em cada tipo de fissura labiopalatina. O teste de Kruskal-Wallis verificou a comparação intergrupos antes e após a cirurgia. Resultados: Os valores médios de nasalância obtidos foram de 40%, 39% e 44% (Pré) e 25%, 24% e 26% (Pós), respectivamente, para FLPB, FLPU e FP. As proporções de casos com fechamento velofaríngeo adequado no pré-cirúrgico e fechamento velofaríngeo adequado no pós-cirúrgico, para os três grupos (FLPB, FLPU e FP) foram de 27%, 6% e 12% e 78%, 75% e 72%, respectivamente. Em ambos os métodos não houve diferença entre os resultados obtidos nos três tipos de fissuras. Conclusão: A CRF mostrou-se igualmente efetiva na correção da insuficiência velofaríngea nos três tipos de fissuras labiopalatinas analisadas: FLPB, FLPU e FP / Introduction: Pharyngeal flap surgery (PFS) is a procedure employed in the treatment of velopharyngeal insufficiency, which main symptom is hypernasality. In order to complement the perceptual findings of speech results of the PFS, instrumental methods such as nasometry and pressure-flow technique are used. Purpose: To investigate the effect of PFS on speech outcomes comparing the three types of more incidents cleft lip and palate: unilateral cleft lip and palate (UCLP), bilateral cleft lip and palate (BCLP) and isolated cleft palate (CP). Methods: Cross-sectional study by means of retrospective analysis of pre- and postoperative findings on nasometric and aerodynamic assessments of 290 patients (73 UCLP, 105 BCLP and 112 CP) who underwent superiorly based pharyngeal flap surgery. Nasalance (acoustic correlate of nasality) is determined during the reading of standardized speech samples, using a nasometer (Kay Elemetrics Corp.), with a cutoff of 27%. In the aerodynamic assessment, the velopharyngeal closure is estimated from the measure of the velopharyngeal minimum cross-sectional area (PERCI-SARS system), during the production of the phone [p], inserted in the word \"rampa\", allowing to estimate it according to the following classification: values from 0 to 4,9 mm2=adequate closure, 5 to 9,9 mm2=adequate-borderline, 10 to 19,9 mm2=borderline-inadequate and 20 mm2=inadequate closure. Paired t-test compared pre and postoperative nasalance scores for each cleft typeand Anova and Tukey tests verified the differences among the three types of cleft lip and palate, in pre- and postoperative condition. Pre- and postoperative velopharyngeal area was analyzed using the Wilcoxon test for each cleft type. The Kruskal-Wallis test verified the comparison between groups before and after surgery. Results: Mean nasalance scores obtained were 40%, 39% and 44% (Pre) and 25%, 24% and 26% (Post), respectively, for BCLP, UCLP and CP. The proportions of cases with inadequate velopharyngeal closure preoperatively and adequate velopharyngeal closure postoperatively for the three groups (BCLP, UCLP and CP), were 67%, 69% and 80% and 78%, 75% and 72%. In both methods there was no difference in the outcomes between cleft type. Conclusion: PFS was shown to be equally effective in correcting velopharyngeal insufficiency in the three types of cleft lip and palate analyzed: BCLP, UCLP and CP

Introdução: Muitos pacientes desenvolvem recidiva de câncer colorretal (CCR), que possui importância epidemiológica devido ao diagnóstico tardio e à dificuldade de acessibilidade à assistência de saúde. Objetivos: analisar as evidências científicas sobre a deiscência de anastomose intestinal em cirurgias por laparotomia e laparoscopia em pacientes com CCR, a recidiva de câncer colorretal e a assistência de enfermagem para pacientes com recidiva de CCR em tratamento cirúrgico; e realizar proposição de assistência de enfermagem perioperatória para esta clientela, com base nestas evidências científicas. Materiais e método: trata-se de revisão integrativa (RI), fundamentada na Prática Baseada em Evidências, realizada com as etapas de elaboração da pergunta e definição das estratégias de busca; elaboração de critérios de inclusão e exclusão; utilização de um instrumento para a coleta de dados da amostra; análise crítica dos estudos com avaliação do rigor e das características da amostra; síntese e interpretação dos resultados; e apresentação da RI. Para a busca da literatura científica utilizou-se os descritores colorectal neoplasms, laparoscopy, laparotmy e anastomoticleak; recurrence e colorectal neoplasm; nas base de dados Cumulative Index to Nursing and Allied Health Literature (CINAHL), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE), Biblioteca virtual COCHRANE, Índice Bibliográfico Español de Ciencias de la Salud (IBECS) e biblioteca virtual National Library of Medicine National Institutes of Health (PUBMED), mediante os critérios de inclusão e de exclusão, com seleção de oito e quatro artigos científicos, respectivamente; e com os descritores colorectal neoplasms, recurrence e nursing, seis artigos científicos. Resultados e discussão: a ocorrência de deiscência de anastomose, foi analisada em relação ao uso de novas técnicas cirúrgicas e maior densidade tecnológica para as terapêuticas adjuvantes, farmacológicas e os exames diagnósticos, que comprometem a mortalidade e sobrevida desta clientela. Em geral, os pacientes apresentam estadiamento avançado da doença, com realização de cirurgia tradicional pela condição clínica associada à comorbidades, maior risco cirúrgico e ampla ressecção intestinal, o que comprometem a sua recuperação fisiológica e psicossocial, além de maior possibilidade de recidiva ou metástases. Para a assistência à saúde desta clientela há necessidade de equipe multidisciplinar, priorizando-se a complexidade clínica, utilização de maior densidade tecnológica e seguimento especializado ao longo da sobrevivência. Há escassez de produção científica, sobre aspectos clínicos, terapêuticos e preventivos, principalmente da enfermagem. Conclusão: O enfermeiro deve ter domínio sobre fisiopatologia, terapêuticas e suas consequências, além de prognósticos e aspectos preventivos do CCR, para prestar assistência de enfermagem perioperatória para pacientes com CCR e familiares, com planejamento de intervenções procedimentais, educativas e psicossociais / Background: Many patients develop colorectal cancer recurrence (CCR), with epidemiological importance due to late diagnosis and the difficult access to health care. Objectives: To analyse scientific evidence on bowel anastomosis dehiscence in laparotomy and laparoscopy surgeries in patients with CCR, the colorectal cancer recurrence and the nursing care for patients with CCR relapse undergoing surgical treatment; and make the perioperative nursing care proposal to these patients, based on the scientific evidences cited. Method and materials: An integrated review (IR), grounded on the Evidence-Based Practice, developed in the following phases: creation of the question and definition of search strategies; creation of inclusion and exclusion criteria; the use of an instrument to collect sample data; critical analysis of the study and assessment of the rigor and characteristics of the sample; summary and interpretation of the results; and IR presentation. In the search for scientific literature, the descriptors colorectal neoplasms, laparoscopy, laparotomy and anastomotic leak; recurrence and colorectal neoplasm were used on the following databases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), LatinAmerican and Caribbean Literatures on health Science (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE), COCHRANE virtual library, Español de Ciencias de la Salud (IBECS) bibliographic index and National Library of Medicine National Institutes of Health (PUBMED) virtual library, using the inclusion and exclusion criteria, selecting 8 and 4 scientific articles, respectively; and 6 scientific articles with the descriptors colorectal neoplasms, recurrence e nursing. Results and discussion: the occurrence of anastomosis dehiscence was analysed in relation to the use of new surgical techniques and greater technological density for the therapeutics adjuvants, pharmacological and the diagnostic tests that affect the mortality and the survival of such patients. In general, patients present advanced staging of the disease with the practice of traditional surgery due to clinic condition associated to comorbidities, greater surgical risk and extensive intestinal resection, which impair their physiological and psychosocial recovery, in addition to a greater possibility of recurrence or metastasis. For the health care of such patients, it is necessary a multidisciplinary team, prioritising the clinical complexity, the use of higher technological density and specialised assistance throughout the survival. There is a shortage of scientific production on clinical, therapeutic and preventive aspects, particularly in nursing. Conclusion: Nurses shall master pathophysiology, therapeutics and their consequences, as well as the prognosis and preventive aspects of CCR in order to provide perioperative nursing care for patients with CCR and their family, with procedural, educational and psychosocial interventions
