Objetivou-se identificar o cuidado realizado pelo enfermeiro para o conforto de pacientes idosos em pós-operatório. Especificamente objetivou-se: 1) Identificar a perspectiva dos enfermeiros sobre os desconfortos nos contextos físico, psicoespiritual, ambiental e sociocultural evidenciados em idosos no pós-operatório; 2) Verificar as características definidoras e os fatores relacionados inseridos ao diagnóstico de enfermagem conforto prejudicado, identificados pelos enfermeiros no idoso em pós-operatório; 3) Identificar as intervenções de enfermagem para promoção do conforto ao idoso em pós-operatório realizadas pelos enfermeiros no seu cuidar. Trata-se de uma pesquisa exploratória, descritiva, de abordagem quantitativa, desenvolvida em um hospital universitário do Município de Natal/RN, Brasil. A população foi constituída pelos 30 enfermeiros que trabalhavam em unidades de internação cirúrgica e terapia intensiva e que prestavam atendimento à pacientes idosos em pós-operatório. Consideraram-se critérios de inclusão: ter tempo mínimo de seis meses de atividade no setor e fazer parte da escala de serviço no período da coleta dos dados. Como critérios de exclusão: estar de licença ou férias no momento da coleta de dados. Toda população formou o grupo de sujeitos do estudo. A coleta de dados foi concretizada em maio e junho de 2014 utilizando um questionário autoexplicativo, composto por quatro partes: I - Caracterização dos enfermeiros; II - Necessidades de conforto do idoso no pós-operatório; III - Diagnóstico de Enfermagem; IV - Intervenções de enfermagem. O projeto foi aprovado pelo Comitê de Ética em Pesquisa (CEP) da Universidade Federal do Rio Grande do Norte, sob CAAE25976613.7.0000.5537. Os dados foram tabulados no Statistical Package for the Social Sciences (SPSS) 20.0 e apresentados utilizando-se frequências, percentuais e medidas de tendência central. Os resultados mostram que 96,7% dos enfermeiros conceituaram conforto como sinônimo de bem-estar. Houve maior frequência do desconforto dor (100%), ruídos excessivos (56,7%), sensação de deslocamento do ambiente residencial (76,7%) e ansiedade (93,3%). Os enfermeiros evidenciaram como sinais e sintomas que caracterizam o desconforto do idoso após cirurgia, principalmente: dor (75,9%), inquietação (58,6%), sinais vitais (41,4%) e ansiedade (34,5%). O principal fator relacionado foi o efeito secundário relacionado ao tratamento (88%). As principais intervenções realizadas foram: ouvir atentamente (100%) e controle da dor (100%). Estas foram igualmente analisadas como prioritárias para esta ação de cuidado, na porcentagem de 76,7% e 66,7%, respectivamente. Conclui-se que os enfermeiros identificam os desconfortos que afetam os idosos no pós-operatório na diversidade dos contextos estudados, com uma ênfase maior aos desconfortos físicos e em especial, a dor. Além disso, possuem uma percepção ampliada sobre os possíveis sinais e sintomas apresentados pelos idosos em pós-operatório quando estão desconfortáveis, uma vez que evidenciam outras 12 características não previstas no Diagnóstico de Enfermagem Conforto prejudicado e também identificam os fatores relacionados a estes desconfortos. Entretanto, apesar de afirmarem que realizam intervenções para amenizá-los e as registrarem, estes dados não podem ser afirmados que se trata de um padrão da prática destes profissionais, uma vez que não foi realizado a observação do cuidado prestado a esta clientela nem avaliação dos prontuários.

Obesity is a chronic disease that has multi-factorial aetiology, characterized by high degree of body fat; the degree of obesity will vary according to the Body Mass Index (BMI=m2 /kg). The severe degree of obesity is characterized by BMI>40 and it is regularly associated to endocrine-metabolic or mechanic clinical alterations, and to psychological disorders. Binge Eating (BE) results were overly high for this population. The Bariatric Surgery has been the treatment chosen by those diagnosed with severe obesity as this intervention provides prompt outcomes for loss of weight and clinical improvement conditions. However, recent research has acquiesced that after two years between 20% and 30% of people subject to this intervention gained weight. The main objective of this research is to assess the psychological and behavioral characteristics of those diagnosed with severe obesity that have been subject to Gastric Bypass Surgery in the past 24 months. Specific aspects were investigated: (1) characteristics of different personalities and diagnose of clinic and personality disorders; (2) BE and its relation with loss of weight; (2) the difference between the groups regarding post-surgery care, e.g. physical activity, psychological and dietician input. Method: 40 adults (women and men) aged 23 and 60 year-old who went through a bariatric surgery in the past 24 months, in the city of Natal-RN (Brazil); they were assembled in two groups n=20, Gain group displaying loss of < 50% of their initial surplus of weight, and the Loss group displaying loss of >50%. The research protocol is made of a socio-demographic questionnaire and 3 psychometric instruments: Rorschach – Comprehensive System; Millon Personality Inventory (MCMI-III); and the Binge Eating Scale (Escala de Compulsão Alimentar Periódica (ECAP). Through Rorschach significant differences between these groups were verified according to the kind of personality (EB) - more EB Extratensivo in Gain group and Intratensivo in Loss group – and the lack of control to express affect, increasing the answer for Color Pure at Group I. Concerning the people standardization, the sample as a whole tends to show psychic pain, denigrated selfperception, high levels of self-criticism, distorted perceptions, vulnerability to develop mood disorders and high scores regarding Suicide. MCMI-III results showed more clinic and personality disorders in Group I: Depressive Disorder and Schizotypal, Anxiety, Dysthymia, Major Depressive Disorder; Thought Disorder, Bipolar- Manic and Posttraumatic Stress Disorder. In relation to ECAP, the results indicated significant differences, showing increased BE results in Gain group. There were found significant differences between BE severity and the presence of clinic and personality disorders. Concerning the post-surgery care, the observed differences are statistically significant regarding physical activities with median-increased differences in Loss group. There is a difference between the initial weight and the time post-surgery, indicating that the higher the initial weight and the time after the surgery the higher the re-gain of weight post-surgery. Finally, the results show that the participants with more than 3 years of surgery will have Clinic and Major Depressive Disorders; Somatoform Disorder; Dysthymia. These results confirm prior studies related to BE post-surgery and re-gain of weight as well as the proneness of clinic disorders in severe obesity people. That means the results reinforce that the surgery process is a facet of the severe obesity treatment. The post-surgery process needs to be the main focus of attention and have a long-term input to sustain the care of the surgery results and the quality of life of the patients.

This study aimed to characterize in a clinical and epidemiological way the patients who are on a waiting list for transplantation and the patients transplanted with corneal tissue in a corneal transplants reference service in the state of Rio Grande do Norte. It is an epidemiological study of a quantitative approach, with cross-sectional, descriptive and analytical cut including all patients on the waiting list for transplantation (population A) and the patients already transplanted with a corneal tissue (population B) in a reference service. In population A, there was a census conducted of patients on the waiting list for corneal transplantation (n=62 patients). In population B, the sample was non-probabilistic and corresponded to all corneal transplants performed in the service in the period from 2010 to 2014 (n=258). This study is approved by the Research Ethics Committee of the Federal University of Rio Grande do Norte, in Opinion 876 177 and CAAE 37533014.8.0000.5537. Data were collected in full in the period from January to April 2015, by two instruments built to systematize the necessary data collection. After being coded and tabulated, data were analyzed using the Statistical Package for Social Sciences software, version 20.0. The definition of variables and their distribution patterns were presented as frequencies and measures of central tendency while, for multivariate analysis, the effect of magnitude measures were applied (prevalence ratio) and measures of association (chi-square test or Fisher's exact test) for a 0.05 significance level. The results are shown in two scientific articles coming from the field survey data. It was found that the epidemiological profile of patients on the waiting list (n=62) showed a prevalence of individuals aged over 50 years old, female (54.84%) and residents of the middle region of East Rio Grande do Norte (66.13%). The clinical profile of patients with corneal transplantation (n=258) was characterized by being male (51.16%) with an average age of 49.33 years old and 57.75% were coming from East Rio Grande do Norte. The average time on the waiting list was 172.63 days in elective transplants and 9.03 days in urgent transplants. Keratoconus was the main indicator condition to perform the transplant. For patients on the waiting list, the variable “type of disorder of the cornea” showed statistically significant association with gender and age. For patients with corneal transplants, the variable "type of disorder of the cornea" was associated with the variables gender, age, previous surgery, failure of previous graft, classification of the eye and glaucoma. By characterizing the clinical and epidemiological profile of corneal transplants, it is possible to question the reality, pointing about the care that should be offered and develop targeted interventions to collective and individual needs intrinsic to patients who need this surgery as a treatment option.

The objective of this randomized, blind and prospective clinical trial was to compare the pain, the edema, the mandibular movements, the masticatory efficiency and life quality, in the first 60 days after surgery using 2 different clinical protocols for myofunctional recovery, in patients who underwent orthognathic surgery. A sample of 19 patients was used and divided into 2 groups. The control group (CG) consisted of 10 patients who had postoperative rehabilitation guided by a standard protocol, conducted by the Service of Surgery and Traumatology Oral and Maxillofacial. In other hand, the experimental group (EC) totaled 9 patients who received the speech therapy rehabilitation protocol specialized, by professionals in the area. The variables pain, edema and mandibular movements were analyzed during 48h, 96h, 7 days, 14 days, 30 and 60 days post-surgery. The masticatory efficiency and the quality of life were classified with 60 days after surgery . The data were submitted an analysis of variance, Student's t-test and Fisher's independence, at the level of 5% probability. It was identified that patients of GE have benefited in the first 14 days(p<0,001), as they have had reported less pain than those in the CG. Significant statistics differences between groups for pain parameters (after 14 days) (p=0,065), edema(p=0,063), mandibular movements(p=0,068), masticatory efficiency(p=0,630) and the impact on quality of life (p=0,813) were not observed on this study. The speech therapy protocol for myofunctional recovery (EG), although it has not obtained statistical results superiors than the CG in the general context, presents itself as a viable alternative to conventional therapy assumed by many maxillofacial surgeons, allowing the surgeon to optimize time with patients in the period postoperatively.

CHAPTER 1 - This study histologically evaluated two implant designs: a classic thread design versus another specifically designed for healing chamber formation placed with two drilling protocols. Forty dental implants (4.1 mm diameter) with two different macrogeometries were inserted in the tibia of 10 Beagle dogs, and maximum insertion torque was recorded. Drilling techniques were: until 3.75 mm (regular-group); and until 4.0 mm diameter (overdrillinggroup) for both implant designs. At 2 and 4 weeks, samples were retrieved and processed for histomorphometric analysis. For torque and BIC (bone-to-implant contact) and BAFO (bone area fraction occupied), a general-linear model was employed including instrumentation technique and time in vivo as independent. The insertion torque recorded for each implant design and drilling group significantly decreased as a function of increasing drilling diameter for both implant designs (p<0.001). No significant differences were detected between implant designs for each drilling technique (p>0.18). A significant increase in BIC was observed from 2 to 4 weeks for both implants placed with the overdrilling technique (p<0.03) only, but not for those placed in the 3.75 mm drilling sites (p>0.32). Despite the differences between implant designs and drilling technique an intramembranous-like healing mode with newly formed woven bone prevailed. CHAPTER 2 - The objective of this preliminary histologic study was to determine whether the alteration of drilling protocols (oversized, intermediate, undersized drilling) present different biologic responses at early healing periods of 2 weeks in vivo in a beagle dog model. Ten beagle dogs were acquired and subjected to surgeries in the tibia 2 weeks before euthanasia. During surgery, 3 implants, 4 mm in diameter by 10 mm in length, were placed in bone sites drilled to 3.5 mm, 3.75 mm, and 4.0 mm in final diameter. The insertion and removal torque was recorded for all samples. Statistical significance was set to 95% level of confidence and the number of dogs was considered as the statistical unit for all comparisons. For the torque and BIC and BAFO, a general linear model was employed including instrumentation technique and time in vivo as independent. Overall, the insertion torque increased as a function of drilling diameter from 4.0 mm, to 3.75 mm, to 3.5 mm, with a significant difference in torque levels between all groups (p<0.001). Statistical assessment of BIC and BAFO showed significantly higher values for the 3.75 mm (recommended) drilling group was observed relative to the other two groups (p<0.001). Different drilling dimensions resulted in variations in insertion torque values (primary stability) and different pattern of healing and interfacial remodeling was observed for the different groups. CHAPTER 3 - The present study evaluated the effect of different drilling dimensions (undersized, regular, and oversized) in the insertion and removal torques of dental implants in a beagle dog model. Six beagle dogs were acquired and subjected to bilateral surgeries in the radii 1 and 3 weeks before euthanasia. During surgery, 3 implants, 4 mm in diameter by 10 mm in length, were placed in bone sites drilled to 3.2 mm, 3.5 mm, and 3.8 mm in final diameter. The insertion and removal torque was recorded for all samples. Statistical analysis was performed by paired t tests for repeated measures and by t tests assuming unequal variances (all at the 95% level of significance). Overall, the insertion torque and removal torque levels obtained were inversely proportional to the drilling dimension, with a significant difference detected between the 3.2 mm and 3.5 mm relative to the 3.8 mm groups (P < 0.03). Although insertion torque–removal torque paired observations was statis- tically maintained for the 3.5 mm and 3.8 mm groups, a significant decrease in removal torque values relative to insertion torque levels was observed for the 3.2 mm group. A different pattern of healing and interfacial remodeling was observed for the different groups. Different drilling dimensions resulted in variations in insertion torque values (primary stability) and stability maintenance over the first weeks of bone healing.

As fraturas que ocorrem no osso osteoporótico são por definição estrita fraturas patológicas. Podem estar relacionadas com quedas da própria altura ou de traumatismos de baixa energia cinética e envolvem habitualmente a anca, o punho, a coluna vertebral e o ombro. As fraturas osteoporóticas a que se associa a sarcopenia, representam um sério problema de saúde pública em todo o mundo, com uma proporção epidémica e um impacto devastador na morbilidade e mortalidade dos pacientes, assim como nos custos socioeconómicos. Apesar dos avanços registados na prevenção e no tratamento farmacológico da osteoporose bem como no tratamento cirúrgico das fraturas ósseas, continuam a ser desenvolvidos novos biomateriais metálicos e substitutos sintéticos do osso com a intenção de se conseguir alcançar melhores resultados clínicos. Dentro deste contexto incluem-se os cimentos hidráulicos, os parafusos expansivos, os parafusos dinâmicos, as malhas metálicas de titânio, as placas bloqueadas, entre outros, em conjugação com técnicas minimamente invasivas e com diferentes estratégias cirúrgicas. O objetivo central deste trabalho assenta nas modalidades cirúrgicas mais usadas para o tratamento das fraturas em osso osteoporótico, com especial destaque para as fraturas da coluna vertebral.

Dois estágios cirúrgicos, somados a um período de cicatrização de três a seis meses, com a ausência de cargas funcionais foram estabelecidos por Bränemark, em 1977, como protocolo cirúrgico da terapia com implantes osteointegrados. Somente após esse tempo de cicatrização, poderia ocorrer a activação dos implantes e confecção das próteses. O desenvolvimento de vários estudos, com a finalidade de abreviar esse período de cicatrização, a simplificação da terapia restauradora, somados aos avanços tecnológicos, e aos altos índices de sucesso, tornaram os implantes imediatos com carga imediata, uma realidade na reabilitação total ou parcial com implantes, abreviando o tempo de cicatrização, com a colocação de uma prótese provisória imediata, logo no final do primeiro estágio cirúrgico. Para a pesquisa bibliográfica foram utilizadas as palavras-chave immediate loading, immediate provisionalization, post-extractive implant, immediate implant, single tooth implant, post extraction sockets, immediate temporization.

A Medicina Dentária é uma área da medicina em que os profissionais podem realizar procedimentos cirúrgicos invasivos e prescrever formulações farmacológicas de maneira autónoma, a partir de diagnósticos realizados por eles próprios. O exercício das atividades médicas deve ser pautado em princípios éticos, legais e na compreensão da realidade social, económica e cultural do local onde exercem os profissionais. Para tanto, o estudo dos Códigos Deontológicos e dos Códigos de Ética e Deontológicos são importantes instrumentos na busca por este paradigma de conduta. O Objetivo deste trabalho de pesquisa pretende comparar o Código Deontológico de Medicina Dentária em Portugal com o Código de Ética Odontológica Brasileiro, buscando diferenças e semelhanças. Realizou-se uma revisão bibliográfica do Código Deontológico Português e do Código de Ética Odontológica Brasileiro, utilizando-se dos próprios códigos, livros e artigos pertinentes ao estudo. Pode-se verificar que ambos os códigos são Completos. O Código Deontológico Português é complementado por Regulamentos internos da Ordem dos Médicos Dentistas. Existem temas específicos no Código Brasileiro que não estão presente no Código Português.
