Avaliou-se o emprego da microscopia eletrônica de varredura no estudo da reação respiratória pós-vacinal em epitélio traqueal de patos (Anas platyrhynchos) imunizados contra a doença de Newcastle. Foram utilizadas 48 aves, distribuídas em quatro grupos: T1 - grupo de aves-controle (não vacinadas), T2 - grupo de aves vacinadas com a estirpe Ulster 2C, T3 - grupo de aves vacinadas com a estirpe B1 e T4 - grupo de aves vacinadas com a estirpe LaSota. Independente do grupo experimental, as aves não apresentaram sinais clínicos detectáveis de reação respiratória pós-vacinal. Ao microscópio eletrônico de varredura, observou-se que os animais vacinados com as estirpes B1 e LaSota desenvolveram descamação epitelial da traqueia, enquanto os vacinados com a estirpe Ulster 2C não, mostrando um epitélio traqueal íntegro, semelhante ao do grupo-controle. Os patos vacinados com a estirpe B1 mostraram evidências de regeneração epitelial da traqueia decorridos 21 dias pós-vacinação, o que não ocorreu com os vacinados com a amostra LaSota.

Objective: To analyze the effect of arm bracing posture on respiratory muscle strength and pulmonary function in patients with Chronic Obstructive Pulmonary Disease (COPD).Methods: 20 patients with COPD (11 male; 67 +/- 8 years; BMI 24 +/- 3 Kg . m(-2)) were submitted to assessments of Maximal Inspiratory and Expiratory Pressures (MIP and MEP, respectively) and spirometry with and without arm bracing in a random order. The assessment with arm bracing was done on standing position and the height of the support was adjusted at the level of the ulnar styloid process with elbow flexion and trunk anterior inclination of 30 degrees promoting weight discharge in the upper limbs. Assessment without arm bracing was also performed on standing position, however with the arms relaxed alongside the body. The time interval between assessments was one week.Results: MIP, MEP and maximal voluntary ventilation (MW) were higher with arm bracing than without arm bracing (MIP 64 +/- 22 cmH(2)O versus 54 +/- 24 cmH(2)O, p = 0,00001; MEP 104 +/- 37 cmH(2)O versus 92 +/- 37 cmH(2)O, p = 0,00001 and MW 42 +/- 20 L/min versus 38 +/- 20 L/min, p = 0,003). Other variables did not show statistical significant difference.Conclusion: The arm bracing posture resulted in higher capacity to generate force and endurance of the respiratory muscles in patients with COPD.

Background: It was already evidenced decreased heart rate variability (HRV) in chronic obstructive pulmonary disease (COPD) patients at rest.Objective: In order to insert new elements in the literature regarding this issue, we evaluated geometric index of HRV in COPD subjects.Method: We analyzed data from 34 volunteers, divided into two groups according to spirometric values: COPD (17 volunteers, FEV1/FVC = 47.3 +/- 10.2; FEV1 = 50.8 +/- 15.7) and control (17 volunteers, FEV1/FVC = 78.8 +/- 10.8; FEV1 = 100.1 +/- 14.7). For analysis of HRV indexes the volunteers remained in the supine position for 30 minutes. We analyzed the following indexes: triangular index (RRtri), triangular interpolation of RR intervals (TINN) and Poincare plot (SD1, SD2 and SD1/SD2). Student t test for unpaired samples and Mann-Whitney test were used for data analysis.Results: We observed statistically significant reductions in geometric indexes in the COPD group: RRtri (0.043 +/- 0.01 vs. 0.059 +/- 0.02; p = 0.018), TINN (105.88 +/- 51.82 vs. 151.47 +/- 49.9; p=0.014), SD1 (9.76 +/- 4.66 vs. 14.55 +/- 6.04; p = 0.014) and SD2 (34.86 +/- 17.02 vs. 51.51 +/- 18.38; p = 0.010). SD1/5D2 (0.30 +/- 0.11 vs. 0.28 +/- 0.07; p = 0.605) were not significantly different between groups. Patients with COPD presented a visual analysis of Poincare plot of lower dispersion of RR intervals both beat to beat and the long term.Conclusion: Subjects with COPD present reduction of geometric indexes of HRV, indicating reduced heart rate variability.

Background: Obesity impairment to the pulmonary function related to the magnitude of adiposity and is associated with excessive daytime sleepiness (EDS) and snoring, among others symptoms of respiratory disorders related to sleep. It is possible that obese individuals with excessive daytime sleepiness may make changes in lung function on spirometry monitored during the day as a consequence of fragmented sleep or episodes of nocturnal hypoventilation that cause respiratory and changes that can persist throughout the day. The combination of these findings alone sleepiness observed by subjective scales with pulmonary function in obese patients is unknown. Objective: To assess the influence of EDS and snoring on pulmonary function in morbidly obese and distinguish between different anthropometric markers, the snoring and sleepiness which the best predictors of spirometric function and respiratory muscle strength and endurance of these patients. Methods: We evaluated 40 morbidly obese markers on the anthropometric, spirometric respiratory variables, maximal inspiratory and expiratory pressures (MIP and MEP) and maximal voluntary ventilation (MVV) and the measured excessive daytime sleepiness (the Epworth sleepiness scale) and snoring (snoring scale of Stanford). The data were treated when the differences between the groups of obese patients with and without sleepiness, whereas the anthropometric variables, respiratory and snoring. Pearson's correlation was performed, and multiple regression analysis assessed the predictors of pulmonary function. For this we used the software SPSS 15.0 for windows and p <0.05. Results: 39 obese patients were included (28 women), age 36.92+11.97y, body mass index (BMI) 49.3+5.1kg/m², waist-hip ratio (WHR) 0.96+0.07 and neck circumference (NC) 44.1+4.2 cm. Spirometric values and respiratory pressures were up 80% of predicted values, except for endurance (MVV <80%). Obese with EDS have lower tidal volume. Positive correlation was observed between BMI and EDS, EDS and NC and between snoring and BMI, and negative correlation between EDS and tidal volume (TV), and between snoring and snoring FVC and FEV1. In linear regression the best predictor of pulmonary function was snoring, followed by NC. NC has more obese with higher strength (MEP, p = 0.031) and endurance (MVV p = 0.018) respiratory muscle. Conclusion: Obese with EDS tend to have lower TV. In addition, snoring and NC can better predict pulmonary function in obese when compared with other anthropometric markers or EDS. Obese patients with higher NC tend to have greater capacity for overall strength of respiratory muscles, but may have low muscle endurance

INTRODUCTION: Cardiac and pulmonary manifestations of the Chagas disease (CD) affect between 20-30% of the infected subjects. The chronic Chagas cardiomyopathy (CCC) has some peculiarities such as arrhythmias and, especially heart failure (HF) and is potentially lethal due to left ventricular dysfunction. How respiratory disorders, patients get progressive loss of functional capacity, which contributes to a poor quality of life related to disease. Measurements of lung volume by the movement of the chest wall surface are an alternative evaluation of lung function and kinematics of complex thoracoabdominal for these patients. OBJECTIVE: evaluate the kinematics of the thoracoabdominal complex through the regional pulmonary volumes and to correlate with functional evaluation of the cardiorrespiratory system in patients with Chagas disease at rest. MATERIALS AND METHODS: a cross-section study with 42 subjects had been divided in 3 groups, 15 composed for patients with CCC, 12 patients with HF of different etiologies and 15 healthful presented control group. An optoelectronic plethysmography (POE), Minnesota questionnaire, six minute walk test, spirometer and manovacuometer was used. RESULTS: It was observed in the 6MWT where group CRL presented greater distance 464,93±44,63m versus Group HF with 399,58± 32,1m (p=0,005) and group CCC 404±68,24m (p=0,015), both the groups presented difference statistics with regard to Group CRL. In the manovacuometer 54,59±19,98; of the group CCC and 42,11±13,52 of group IC found group CRL presented 81,31±15,25 of the predicted versus, presenting in relation to group CRL. In the POE it observed a major contribution in abdominal compartment in patients with IC if compared like CCC and control groups. On the basis of the questionnaire of quality of life of Minessota, verified a low one groups CCC and IC 43,2±15,2 and 44,4±13,1, respectively (p<0,05) when compared with the control group (19,6±17,31). CONCLUSION: it seems that the patients with CCC possess same functional and respiratory characteristics, observed for the POE, 6MWT, manovacuometer and spirometer to the patients of group HF, being able to consider similar interventions for this complementary group as therapeutical of this neglected disease

O Acidente Vascular Cerebral (AVC) é uma síndrome clínica caracterizada por uma perturbação focal da função cerebral. Geralmente ocasiona quadro de disfunção motora acompanhada de prejuízo da função respiratória. Tendo em vista tal quadro e suas possíveis repercussões, a fisioterapia respiratória tem sido amplamente requisitada com o intuito reverter ou minimizar as complicações. Dentre os recursos utilizados para este fim, os espirômetros de incentivo são utilizados com o objetivo de restaurar os volumes pulmonares, modificando o padrão respiratório e de ventilação pulmonar, prevenindo a incidência das complicações pulmonares. O objetivo do presente estudo foi comparar o desempenho na realização da espirometria de incentivo volume-orientada (EI) e seus efeitos agudos sobre os volumes pulmonares em pacientes após AVC e sujeitos saudáveis. Foram selecionados 40 voluntários, de ambos os gêneros, divididos em grupo experimental (GE), composto por 20 pacientes após AVC e grupo controle (GC) composto por 20 sujeitos saudáveis, pareados quanto à idade, gênero e Índice de Massa Corpórea (IMC). A coleta dos dados foi realizada em duas etapas: (1) Avaliação cognitiva e neurofuncional (Mini Exame do Estado Mental, National Institute Stroke Scale, Medida de Independência Funcional, teste de desempenho da aprendizagem) (2) Avaliação Respiratória (espirometria, manovacuometria e cinemática tóraco-abdominal, através da Pletismografia Opto-eletrônica). A análise estatística foi realizada através do software Graphpad Prism 4.0, em que foram utilizados os testes t Student e ANOVA two-way para comparação intergrupos e adotado nível de significância de 5%. Os resultados mostraram que os pacientes apresentam desempenho inferior na aprendizagem da espirometria de incentivo, com uma média de erros maior 2,95 ± 1,39, quando comparados aos sujeitos saudáveis, 1,15 ± 0,98. Em relação à prática observacional utilizada não foi encontrada diferença entre a aprendizagem através do vídeo ou do terapeuta. Em relação aos efeitos agudos da espirometria de incentivo volume-orientada, os pacientes após AVC apresentaram valores de volume corrente 24,7%, 18% e 14,7% inferiores quando comparados aos sujeitos saudáveis nos momentos pré-EI, EI e pós-EI, porém a espirometria de incentivo induziu incrementos de volume similares em ambos os grupos estudados, com 75, 3% para os pacientes e 73,3% para os sujeitos saudáveis. A espirometria de incentivo promove ganhos significativos no volume corrente da parede torácica, tanto em pacientes acometidos por AVC como em sujeitos saudáveis, no entanto o desempenho da aprendizagem é inferior para os pacientes, para ambas as práticas com vídeo ou terapeuta

Introduction: The leukemias are the most common malignancy in children and adolescents. With the improvement in outcomes, there is a need to consider the morbidity to generate the protocols used in children under treatment. Aim: To evaluate pulmonary function in children with acute leukemia. Method: This study is an observational cross sectional. We evaluated 34 children distributed in groups A and B. Group A comprised 17 children with acute leukemia in the maintenance phase of chemotherapy treatment and group B with 17 healthy students from the public in the city of Natal / RN, matched for gender, age and height. The thoracic mobility was evaluated by thoracic expansion in the axillary and xiphoid levels. Spirometry was measured using a spirometer Microloop Viasys ® following the rules of the ATS and ERS. Maximal respiratory pressures were measured with digital manometer MVD300 (Globalmed ®). The maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were measured from residual volume and total lung capacity, respectively. The data were analyzed using the SPSS 17.0 software assigning the significance level of 5%. Descriptive analysis was expressed as mean and standard deviation. T'student test was used to compare unpaired values found in group A with group B values, as well as with the reference values used. To compare the respiratory coefficients in the axillary level with the xiphoid in each group, we used paired testing t student. Results: Group A was significantly decreased thoracic mobility and MIP compared to group B, and MIP compared to baseline. There was no significant difference between spirometric data from both groups and the values of group A with the reference values Mallozi (1995). There was no significant difference between the MIP and MEP values and lower limits of reference proposed by Borja (2011). Conclusion: Children with acute leukemia, myeloid or lymphoid, during maintenance phase of chemotherapy treatment have reduced thoracic mobility and MIP. However, to date, completion of clinical treatment, the spirometric variables and the strength of the expiratory muscles appear to remain preserved in children between five and ten years

Pulmonary Rehabilitation, especially due to aerobic exercise, positive impact in reducing morbidity/mortality of patients with COPD, however the economic impact with costs of implementing simple programs of aerobic exercise are scarce. This is a blind randomized clinical trials, which aimed to evaluate the costs and benefits of a simple program of aerobic exercise in individuals with COPD, considering the financial costs of the Public Health System and its secondary endpoints. We evaluated lung function, the distance walked during six minutes of walking, the respiratory and peripheral muscle strength, quality of life related to health (QLRH), body composition and level of activity of daily living (ADL) before and after eight weeks of an aerobic exercise program consisting of educational guidance for both groups, control and intervention and supervised walks to the intervention group. The health costs generated in both groups were calculated following table Brazilian Public Health System. The sample consisted of forty patients, two being excluded in the initial phase of desaturation during the walk test six minutes. Were randomized into control and intervention group thirty-eight patients, three were excluded from the control group and one was excluded from the intervention group. At the end, thirty-four COPD comprised the sample, 16 in the control group and 18 in the intervention group (FEV1: 50.9 ± 14% pred and FEV1: 56 ± 0.5% pred, respectively). After for intervention, the intervention group showed improvement in meters walked, the sensation of dyspnea and fatigue at work, BODE index (p <0.01) in QLRH, ADL level (p <0.001) as well as increased strength lower limbs (p <0.05). The final cost of the program for the intervention group was R $ 148.75, including: assessments, hiking supervised by a physiotherapist and reassessments. No patient had exacerbation of IG, while 2 patients in the CG exacerbated, generating an average individual cost of R $ 689.15. The aerobic exercises in the form of walking showed significant clinical benefits and economic feasibility of its implementation, due to low cost and easy accessibility for patients, allowing them to add their daily practice of aerobic exercises

The evaluation criteria of the cases treated with dental implants are based on clinical and radiographic tests. In this context it is important to conduct research to determine prognosis of different types of prosthetic rehabilitation and determination of the main problems affecting this type of treatment. Thus, the objective of this study was to assess the prosthetic conditions of individuals rehabilitated with implant-supported prosthesis. In this cross-sectional study 153 patients were treated, accounting for a sample of 509 implants. The failures were observed by clinical and radiographic examination. The results showed that the fracture (0.2%) loss (0.4%) and loosening of the screws (3.3%) were failures are less frequent. The fracture structures as the resin (12.4%), porcelain (5.5%) and metallic (1.5%), loss of resin that covers the screw (23.8%) and loss of retention overdentures on implants (18.6%) had a higher occurrence. The failure of adaptation between the abutment and the implant (6.9%) and especially between the prosthesis and the abutment (25.4%) had a high prevalence and, when related to other parameters showed a significant association, particularly with the cemented prosthesis (OR = 6.79). It can be concluded that to minimize the appearance of failures, protocols must be observed from diagnosis to the settlement and control of prostheses on implants, particularly with respect to technical steps of the making of the prosthesis and care in radiographic evaluating the fit between their components

Aim: To determine the frequency and type of complications related to removable partial denture (RPD) less, Kennedy Class I, over time . Materials and Methods: This observational study consisted of a sample of 65 users PPR lower arches in Kennedy Class I and dentures, rehabilitated in the Department of Dentistry, Federal University of Rio Grande do Norte (UFRN). Patients were followed through periodic controls during periods of 60 days, 6 months and 1 year from installation. After the first year of control had other returns annually. The occurrence of complications or prosthetic failure was observed and recorded in a specific clinical record over 39 months. The patterns of failures observed were classified in the following situations: occurrence of traumatic ulcers after 2 months of installation, lack of retention, fracture or caries in the rest, fracture or dislocation of the artificial teeth, the larger connector fracture, fracture clip fracture support, poor support (need to reline the denture) and prosthesis fracture. Results: The incidence of complications was low frequency, being higher in the second year of use of the prosthesis. Among the complications that occurred more is the loss of retention (31.57%). Failures more severe and difficult to solve as the fracture elements of the metal structure of the PPR had low occurrence and were represented by only one case of the larger connector (5.3%) fractures. Conclusion: Removable partial dentures mandibular free end opposing of the conventional dentures have a low complication rate after 39 months of use when subjected to periodic controls

JUSTIFICATIVA E OBJETIVOS: Diversos modelos experimentais têm sido utilizados para ilustrar as alterações hemodinâmicas e metabólicas que ocorrem durante o choque hemorrágico. O objetivo da pesquisa é o de observar os comportamentos hemodinâmicos e metabólicos que acontecem em um modelo seqüencial e progressivo de choque hemorrágico no cão, verificando quais índices alteram-se mais precocemente. MÉTODO: O estudo foi realizado em 13 cães sob anestesia venosa total com pentobarbital sódico, em normoventilação e previamente esplenectomizados. Os animais não foram hidratados e a velocidade do sangramento foi ditada pela pressão arterial em que o animal se encontrava. Os atributos estudados foram divididos em hemodinâmicos (freqüência cardíaca - FC, pressão arterial média - PAM, índice de resistência vascular sistêmica - IRVS, índice sistólico - IS, índice cardíaco - IC, índice de choque - I.choque, índice de trabalho sistólico do ventrículo esquerdo - ITSVE, pressão capilar pulmonar - PCP, pressão venosa central - PVC) e metabólicos (saturação venosa mista - SvO2, pressão venosa de oxigênio - PvO2, transporte de oxigênio - DO2, consumo de oxigênio - VO2, extração de oxigênio - TEO2, lactato sérico). A coleta de dados e os atributos foram estudados em 6 momentos distintos, sendo M1, o momento controle e os outros momentos correspondentes a decréscimos gradativos de 10% da volemia calculada para cada animal. RESULTADOS: A hemorragia determinou diminuição significativa da FC somente em M6; queda da PAM, IC, IS e ITSVE a cada momento estudado; discreta alteração da PVC e PCP em cada momento; diminuição da PvO2 e da SvO2 nos momentos estudados; redução do DO2, estabilização do VO2 e elevação da TEO2 nos momentos; o índice de choque apresentou elevação até M3, diminuição em M4 e nova elevação até M6; o IRVS elevou-se até M6, ficou inalterado em M5 e apresentou diminuição significativa em M6; o lactato apresentou elevações a partir de M5 e M6. CONCLUSÕES: Considerou-se que a pressão arterial média, freqüência cardíaca, pressão venosa central e pressão capilar pulmonar não refletem o real estado volêmico dos cães no nosso modelo experimental e que o transporte, consumo e a taxa de extração de oxigênio são parâmetros úteis na determinação da reversibilidade e prognóstico do choque hemorrágico.

JUSTIFICATIVA E OBJETIVOS: A sedação de dependentes de álcool e drogas em Unidades de Terapia Intensiva (UTI) é um desafio pela elevada incidência de tolerância às drogas sedativas e da elevada freqüência de síndromes de abstinência. O objetivo deste relato é mostrar um caso de paciente jovem admitido na UTI que desenvolveu síndrome de abstinência alcoólica e tolerância às drogas sedativas, solucionadas somente após o uso de clonidina. RELATO do CASO: Paciente do sexo masculino, 18 anos, dependente de álcool, tabaco, cocaína e maconha, vítima de acidente por arma de fogo, foi admitido na UTI no 1º dia de pós-operatório de enterectomia, após aspiração de conteúdo gástrico durante reintubação traqueal. Evolução clínica: drogas vasoativas até o 4º dia de internação e broncopneumonia bilateral com derrame pleural e necessidade de ventilação artificial até o 15º dia. O esquema de sedação inicial utilizado foi a associação de midazolam e fentanil. A partir do 4º dia, o paciente apresentou vários episódios de agitação psicomotora, mesmo com a associação de lorazepam no 6° dia. No 9° dia, o paciente recebeu as maiores doses dos fármacos, mas permanecia agitado. Optou-se pela associação de dexmedetomidina, que reduziu as doses das outras drogas em 35% e diminuiu a agitação. No 12° dia, o midazolam e a dexmedetomidina foram substituídos pela infusão de propofol, com piora do quadro. No 13° dia, foi associada clonidina ao esquema de sedação, com resolução do quadro de agitação. No 14° dia, o propofol foi suspenso, sendo mantida a infusão de fentanil e reintroduzida a infusão de midazolam, com doses respectivamente 75% e 65% menores em relação ao pico de uso destas drogas. No 15° dia, o paciente foi extubado e teve alta da UTI. CONCLUSÕES: A droga de escolha para o tratamento da síndrome de abstinência alcoólica é o benzodiazepínico. Entretanto, no presente relato, somente o uso adjuvante de clonidina conseguiu proporcionar tratamento adequado ao paciente.
