Distúrbios funcionais da oclusão e sua correlação com radiografias transcranianas da articulação temporomandibular, em pacientes portadores de fissuras labiopalatais

Anamnesis, clinical examinations and temporomandibular joint transcraneal radiographs for 22 adults with cleft lip and palate were carried out in order to evaluate the occlusion and correlate it with radographic findings. The conclusions were: 72.8% of the patients have at least one sign or symptom of craniomandibular disorders (CMD); although the occlusal conditions were severely altered, most of the signs and symptoms were classified as mild; the greater frequency of the signs and symptoms occurred among women; in the radiographic evaluation, all of the assymptomatic patients had both condyles with normal contour and all of the patients with altered contour had at least one sign or symptom; the bilateral centered position of the condyles in the fossa e did not warrant the absence of signs and symptoms; some patients with bilateral condyles positioned posteriorly or caudally or even assimetrically, did not present signs and symptoms of dysfunction; the radiographic findings should be correlated with clinical findings; and a great number of patients were not observed with clinical board of C:MD caused by the occlusion. Key words: Radiography; temporomandibular joint; temporomandibular joint syndrome; cleft palate; dental occlusion

Efeitos da Fisioterapia Respiratória na Mecânica Respiratória de Pacientes com Acidente Vascular Encefálico Ventilados Mecanicamente

Patients who went through a Stroke may require mechanical ventilation (MV) in the acute phase of the disease and, on MV, they may show alterations in the respiratory mechanic. Physiotherapy techniques are applied in patients on MV to improve their respiratory mechanic. Thus, the purpose of this study was to evaluate the effects of the Respiratory Physiotherapy into the dynamic compliance (Cdyn), static compliance (Cst) and airway resistance (Rwa) in Stroke patients on MV. In order to do that, patients with Stroke diagnostic on MV were evaluated, before and after the use of Physiotherapy techniques (manual rib-cage compression, thoracic decompression, zero end expiratory pressure and suctioning). Cdyn, Cst and Rwa were the researched variables. Statistical Analysis was made using Paired T-Test with statistical significance with p-values no greater than 5%. Eleven patients were part of the study, with an average of 64,6±12,5 years old. Cdyn increased after physiotherapy from 29,3±16,1 ml/cmH2O to 33,8±16,7 ml/cmH2O (p=0,03). Cst also increased from 44,4±20,7 ml/cmH2O to 54,0±26,6 ml/cmH2O (p=0,024). No significant difference was detected for Rwa between the before and after moments (Before – 8,0±3,2 cmH2O/l/s, After – 7,3±2,25 cmH2O/l/s; p=0,45). It was possible to conclude that both dynamic and static compliance increased after physiotherapy, but the airway resistance did not increase in patients with stroke on mechanical ventilation.

Efeitos da Reeducação Postural Global na Hipercifose e nas Variáveis Respiratórias de Idosos Relato de Dois Casos

Examine the effects Global Postural Reeducation, (GPR) in hyperkyphosis and respiratory variables in the elderly was the objective in the research. For this, two elderly participated, one is 62 years old (voluntary 1) and another is 66 years old (voluntary 2), without lung, heart, kidney and/or skeletal-muscle diseases diagnosed. The volunteer have been assessed for Quality of Life (QOL) through the questionnaire SF-36, the degree of toracic kyphosis, the muscular respiratory strength and the thoracic-abdominal mobility. The GRP treatment consisted in eight sessions applied, once one hour each session. After the eight sessions the volunteer were reevaluated. The data concerning assessments before and after treatment were analysed describly. According to the results there was an improvement in the degree of kyphosis in both volunteers, highlighting voluntary 2. Respiratory variables also improvements after treatment. In relation to the Quality of life in most areas there has been an increase in scores indicating improved QOL. These data showed that the GPR has been effective to decrease the level of kyphosis, improves respiratory variables and the quality of life in the elderly treated. However, further work with a greater number of subjects must be carried out to analyze the effectiveness of therapy in the elderly.

Da prescrição radiográfica: uma análise em medicina bucal

A redução da dose de radiação ao paciente é aceita em Radiologia Odontológica, com a finalidade de diminuir os riscos associados ao exame radiográfico. Para atingir este objetivo, além do avanço tecnológico ocorrido nas últimas décadas, devemos considerar a importância do Critério de Seleção para o paciente e da prescrição radiográfica na indicação correta do tipo de radiografia necessária para cada um deles. O objetivo deste trabalho foi avaliar a prescrição radiográfica de pacientes atendidos pelo Serviço de Medicina Bucal da Faculdade de Odontologia de Araraquara - UNESP durante o período de 1989 a 1993. Selecionamos 396 prontuários que constituiu a totalidade dos que continham exames radiográficos. Para a análise da prescrição radiográfica, consideramos as informações obtidas da ficha clínica e da interpretação das radiografias, utilizando os Critérios de Seleção e a análise de decisão clínica. Os resultados demonstraram um alto índice de pacientes com prescrição incorreta (44,0%); tendo em 24,7% dos pacientes ocorrido mais de uma radiografia prescrita incorretamente. Com relação ao tipo de técnica com prescrição incorreta, em 31,6% dos pacientes foi realizada a radiografia panorâmica, vindo a seguir a oclusal (28,7%), outro (17,2%) e a associação da panorâmica e oclusal (12,6%). Pacientes portadores de doenças e alterações de tecido mole tiveram a mais alta freqüência de prescrições incorretas, seguidos pelos portadores de doenças das glândulas salivares (13,5%) (incluindo os tumores); outros (10,1%); distúrbios da A.T.M. (9,0%); inflamação e infecção dos maxilares (6,8%); tumores benignos (5,6%) e tumores malignos (5,6%). Em 62,9% dos pacientes, o exame radiográfico contribuiu para o diagnóstico e tratamento. A alta porcentagem de prescrição incorreta encontrada evidencia a necessidade de... (Resumo completo, clicar acesso eletrônico abaixo).

Avaliação da instabilidade atlanto-axial em indivíduos com síndrome de Down por meio de radiografias da coluna cervical

O objetivo nesta pesquisa consiste em fazer um trabalho de prevenção junto às instituições APAE (Associação de Pais e Amigos de Excepcionais) e ASIN (Associação de síndrome de Down), ambas de São José dos Campos e ASPAD (Associação de Pais e Amigos de síndrome de Down) de Jacareí, orientando e avaliando sobre a presença ou não da instabilidade atlanto-axial (IAA), assim como verificar a prevalência dessa anormalidade nesses indivíduos. Foram convidados a participar do projeto todos os indivíduos das três instituições de assistência à SD, tendo formado uma amostra com 68 indivíduos, com idades entre 2 a 34 anos, sendo 39 do sexo masculino e 29 do feminino. Foram realizadas radiografias da coluna cervical nas posições de extensão, flexão e neutra, para as quais todos os responsáveis assinaram termo de consentimento. A verificação da IAA foi feita pela análise da distância atlanto-odontóide (DAO), utilizando o programa Radiocef, com uma ferramenta criada para isso. A DAO foi analisada nas três incidências, e era considerada a presença de IAA desde que o indivíduo apresentasse valores ?4,5mm em pelo menos uma dessas posições. Após a realização dos testes estatísticos e análise dos resultados, concluímos que a prevalência de IAA foi de 22,1% dos indivíduos, com valores DAO entre 4,5 e 8,83mm, tendo sido mais prevalente nos indivíduos do sexo masculino do que feminino, assim como nas crianças do que nos jovens e adultos. Foi possível verificar também que, a posição de flexão apresentou maior prevalência de IAA, mas que ela não deve sobrepor às posições de extensão e neutra, pois pode omitir casos ausentes em flexão, mas presentes nas outras posições. Dessa forma, foi realizado o trabalho de prevenção com a avaliação da IAA por meio da realização dos exames radiográficos em que os laudos... (Resumo completo, clicar acesso eletrônico abaixo)

Achados radiográficos e ultrassonográficos em equinos com doença do navicular

The distal sesamoid bone, also known as navicular bone, is located inside the hoof, palmar (thoracic limbs) or plantar (pelvic limbs) to distal interphalangeal joint. Its extremities are fixed by collateral medial and lateral sesamoidean ligament and distal impar sesamoidean ligament. Navicular disease diagnostic is made through a thorough clinical exam, nerve blocks and imaging exams. Even though imaging exams are not conclusive, they are essential to evaluate the extension of soft tissue lesions. Radiographic projections used to evaluate navicular bone are lateromedial (LM); dorsoproximal-palmaro/plantarodistal oblíqua (D30Pr-PaDiO); dorsoproximal-palmaro/plantarodistal oblíqua (D60Pr-PaDiO) e a palmaro/plantaroproximal-palmaro/plantarodistal oblíqua (PaPr-PaDiO). This exam allows to identify number and shape alterations of synovial invaginations on the distal (foramem nutricio) in the distal margin of distal sesamoid, osteophytes, enthesophytes and periarticular lesions. There are four ultrasonographic accesses described in literature to evaluate podotroclear apparatus, they are: palmar or plantar distal do the pastern, through the heel bulbs, through coronary band and transcuneal. These images allow a beeter the evaluation of soft tissue next to the distal sesamoid, because it is more sensitive than radiographic exam to evaluate acute lesions in soft tissues and perioesteum

Desenvolvimento de algoritmos para a avaliação quantitativa de imagens de fantomas mamográficos

There are many advantages when using a phantom for the evaluation of the mammographic images, one of them is to test the visibility of the distribution of objects that constitute it, and then, set the best image in order to obtain a diagnostic medical insurance, trying to reach the best risk - benefit ratio for the patient. Typically, the quality of the mammographic image is performed by subjective and quantitative assessments. This study developed algorithms that can quantitatively evaluate digital images (DICOM), obtained from mammographic phantom consisting of test objects. The results were adjusted by the response of the subjective evaluation performed by experts in radiology. This procedure aims to create an independence of the experts in radiology in daily tests of quality control in routine clinical diagnostic radiology

Respostas cardiovasculares ao exercício resistido em hipertensos: uma revisão sistemática

Adopting a healthy lifestyle it is critical for the prevention of high blood pressure and is an indispensable part of the treatment of those with hypertension. High levels of physical activity and greater fitness are associated with reduced incidence of hypertension. However until the beginning of the 1990 decade, the resisted exercise was not inclued at the internacionals statements for people with heart disease. Fortunately, in the past few years, this type of exercise started to take into account as a possible strategy for the first and second prevention of diferents cardiovascular diseases. The aim of this study it is to evaluate, through a systematic review, the contribution of the resisted exercise on the cardiovascular responses in hypertensive male adults. Twenty eight articles were pre-selected for this study, four attend to the requirements. The results were not consistent in this review, only the diastolic blood pressure demonstrated decrease in three of the four studies, in circuit protocol as much as in the conventional protocol. Otherwise one study proved an increase in the VO2max, wich is an important data, because it is an anaerobic exercise and, an improve was not expected. An other article analised the harm issues of the Valsalva manouvre, where it was presented the maximum blood pressure values (345/245 mmHg) and evidences of lower blood pressure rises in the intra-arterial, intrathoracic and intra-abdominal pressures when the exercise was performed without the manouvre, enhancing the necessity to avoid the use of this manouvre in hypertensive individuals.

Controle de qualidade em equipamentos mamográficos

Nowadays the mammography is the most effective way of revealing early breast cancer. The image in this kind of exam is gotten trough a x-ray sheaf of low energy, however, the suitable visualization of the interesting structures by the radiologist is not always possible due several factors that appears since the mamma composition until the equipments limitation. The regulation 453/98 sets quality control tests and limits of acceptation that guarantee a good development of the mammographys. The purpose of this study is the 3D principle ( Diagnostic, Dose and Dollar), that means, an improved diagnosis, a dose reduction in the patient and a cost decrease for the Institution. In this study was made the quality control tests set by the Regulation in two mammography equipments from Hospital das Clínicas da Faculdade de Medicina de Botucatu (HCFMB - UNESP). The results reached in this research were used in the renovation process of quality stamp in mammography granted by Colégio Brasileiro de Radiologia (CBR) to the diagnosis by image from the HCFMB – UNESP

Doença do trato inferior (DITUI) em felinos doméstico

Lower urinary tract disease (LUTD) is a multifactorial disease, wich may be caused by uroliths and calculations, bacterial and viral infections and anatomical abnormalities, among others. The disease can also be of unknown origin in wich case it is called intersticial cystitis. Knowing that the disease may have many causes, it is necessary to know the exact etiology and the best method of diagnosis, to establish specific therapeutic measures for each case. The diagnostic methods most commonly used are: urinalysis, radiography and ultrassonography, but the blood count and biochemistry can be used, trying to assess the overall status of the animal. The terapy used depends on the causative agent of disease, wich may include changes in supply until emergency treatment, azotemia in cats with post-renal. The present study aims to present a complete study of a disease, addressing it’s etiology, diagnosis and treatment, with particular attention to first item
