Phase of enhancement and plane of reconstruction affect the appearance of the normal canine small intestine when utilizing triple-phase computed tomographic angiography

Hatfield, Jordan Taylor 01 May 2020 (has links)
The use of computed tomography in patients with gastrointestinal disease is increasing. However, the triple-phase computed tomographic angiographic appearance of the canine small intestine and the effects that phase of contrast enhancement and plane of reconstruction have on the appearance of the small intestine have not been fully evaluated. The purposes of this study were to investigate these effects on the appearance of the small intestinal wall. The minimal and maximal small intestinal diameter, wall thickness, number of wall layers identified, and degree of mucosal enhancement were recorded. The plane of reconstruction did not have any significant effects on wall thickness, diameter, degree of mucosal enhancement, or number of wall layers identified. There was a positive association between body weight and intestinal diameter. The arterial phase demonstrated the greatest mucosal enhancement and number of wall layers identified. The transverse plane was subjectively the most useful for evaluation of the small intestines.

Der diagnostische Stellenwert des Mehrschicht-Spiral-CT bei Patienten mit Verdacht auf Darmischämie

Jungblut, Robert 21 April 2005 (has links)
Fragestellung: Wie nützlich ist das Mehrschicht-Spiral-CT bei der Diagnostik der Darmischämie? Studiendesign: Retrospektive Studie Patientenkollektiv: 112 Patienten, die in einem Zeitraum von drei Jahren bei Verdacht auf Darmischämie in einem Mehrschicht-Spiral-CT untersucht wurden. Ergebnis: Bei den 112 Verdachtsfällen handelte es sich in 26 Fällen um eine Darmischämie. Das CT erkannte davon 24 (92%), ein Fall wurde falsch negativ (4%) befundet und ein Fall (4%) wurde als unklar eingestuft. Von den 86 Fällen ohne Darmischämie wurden 77 (89%) korrekt erkannt, drei (4%) wurden falsch positiv befundet und 6 (7%) Fälle wurden als unklar eingestuft. Die Ergebnisse der bei manchen Patienten zusätzlich durchgeführten Sonografie – und Röntgenuntersuchungen waren erheblich schlechter (Sono: Sensitivität: , Spezifität: ; Röntgen: Sensitivität: , Spezifität: ). Die erhobenen Laborparameter (Leukozyten, Lactat, D-Dimere) waren zur Beurteilung, ob es sich um eine Darmischämie handelt, nicht spezifisch genug. Schlussfolgerung: Das Mehrschicht-Spiral-CT ist mit einer Sensitivität von 92% und einer Spezifität von 97% gut zur Erkennung einer Darmischämie geeignet. Unklare Fälle sind mit hoher Wahrscheinlichkeit nicht operationswürdig. / Objective: To verify the diagnostic importance of helical CT in the diagnosis of mesenteric ischemia. Design: Retrospective study Subjects: 112 patients, who where examined by helical CT during a 3-year-period, with suspected mesenteric ischemia. Main Outcome: 26 cases proved to be mesenteric ischemia. Helical CT was diagnostic in 24 (92%) cases, wrong in one (4%) case and uncertain in one (4%) case. No ischemia was correctly diagnosed in 77/86 (89%) cases, wrongly in three (4%) and 6 (7%) were uncertain. Sonografie and plain film radiographs were taken on some patients, but the results were unsatisfactory. Sonography: Sensitivity: 0%, specificy: 85,7%. Plain film radiographs sensitivity: 0%, specificy: 100%. Results of laboratory test were of little diagnostic value (white blood cell count, lactate, d-dimere). Conclusions: Helical CT is a valuable tool for detecting mesenteric ischemia with a sensitifity of 92% and a specificy of 97%. Suspected mesenteric ischemia which cannot be proved by helical CT are most probable non surgical cases.

Contribution à la compréhension du comportement de l'abdomen lors d'un chargement dynamique frontal par une ceinture de sécurité

Lamielle, S. 07 July 2008 (has links) (PDF)
Les études d'accidents montrent que l'abdomen est devenu le segment prioritaire à protéger pour un occupant ceinturé lors d'un choc automobile frontal, les lésions étant imputables au phénomène de sous marinage. Par ailleurs, un mauvais positionnement de la ceinture de sécurité peut également être à l'origine de lésions lors du déclenchement des prétensionneurs. Ces deux phénomènes entrainent un chargement dynamique de l'abdomen par la ceinture, les vitesses pouvant aller de 4m/s à 8m/s. Le but de cette étude est d'accroitre notre compréhension du comportement de l'abdomen et des mécanismes lésionnels afin d'élaborer un modèle prédictif du risque lésionnel utilisable pour le développement et l'amélioration des systèmes de protection de l'occupant. Pour étudier la réponse de l'abdomen face à un chargement dynamique par une ceinture huit essais sur huit Sujets Humains Post Mortem (SHPM) ont été réalisés. Quatre essais simulaient le phénomène de sous marinage et quatre celui de la prétension de la ceinture. Des bilans d'efforts complets, des mesures de déplacement, de déformées externes de la paroi abdominale, des radiographies et des mesures de pressions ont été réalisés. Les essais disponibles dans la littérature et les résultats expérimentaux ont conduit à développer un modèle masse-ressort-amortisseur reproduisant les principes pilotant le comportement de l'abdomen. Ce modèle souligne le caractère viscoélastique, non linéaire et inertiel de l'abdomen. L'exploitation des mesures réalisées associées aux bilans lésionnels a permis d'apporter des méthodes de validation des modèles numériques par éléments finis et d'améliorer la formulation du modèle être humain HUMOS2

Ultrassonografia abdominal de cães e gatos hígidos, adultos e filhotes /

Santos, Ivan Felismino Charas dos. January 2009 (has links)
Orientador: Maria Jaqueline Mamprim / Banca: Sheila Canavese Rahal / Banca: Luciana Del Rio Pinoti Ciarlini / Resumo: O emprego do exame ultrassonográfico na medicina veterinária é amplamente difundido como meio de diagnóstico complementar, principalmente para os tecidos moles e recentemente também da superfície dos tecidos ósseos. A presente pesquisa teve por objetivo analisar, de forma comparativa, a anatomia ultrassonográfica normal do fígado, rim, glândulas adrenais, baço, bexiga urinária e pâncreas de cães e gatos, adultos e filhotes, estabelecer padrões de normalidade e valores de referência e desenvolver material didático para o aprendizado da ultrassonografia em pequenos animais. Foram utilizados 20 animais em condições hígidas, de raças variadas sem predileção de sexo, divididos em: grupo C1- cinco cães adultos e C2 cinco cães filhotes, G1 cinco gatos adultos e G2 cinco gatos filhotes. Os animais foram preparados para o exame ultrassonográfico abdominal com jejum de 6 a 8 horas e administração de antifiséticos. Observou-se que cães e gatos adultos apresentaram o fígado com ecotextura de maior granulação em relação aos filhotes. A parede da vesícula biliar do gato filhote sempre foi visibilizada. O hilo esplênico ofereceu maior dificuldade de visibilização entre os felinos. O sinal de margem medular renal não foi evidenciado nos cães adultos e filhotes, mas esteve presente em todos os gatos adultos e eventualmente em alguns filhotes. A glândula adrenal do gato filhote foi visibilizada com ecogenicidade hipoecogênica difusa e no gato adulto permitiu ótima distinção da medular e cortical da glândula adrenal. Portanto, para se realizar com propriedade um exame ultrassonográfico abdominal, há necessidade de conhecimento sólido de anatomia topográfica, princípios de formação da imagem, suas interações e padrões de normalidade e tendo sempre em mente as particularidades de cada espécie. / Abstract: The ultrasound is widespread as a complementar diagnostic for soft tissue and for bone's surface in veterinary medicine. This study aimed to compare and standardize the normal anatomy ultrasonography of the liver, kidney, adrenal glands, spleen, bladder and pancreas on dogs and cats, adults and young, and development of didactic material for the learning of abdominal ultrasonography in small animals. Twente animals in healthy condition, mixed breed, male and female, were used, divided in four goups. Group C1 (five adults dogs), group C2 (five puppies), group G1 (five adults cats) and group G2 (five kittens). Before the exams, the animals were given antifizetics and fasting for six to eight hours. Adult animals had the liver echotexture with a larger thickness and the gallbladder wall always was visualized in kittens. The splenic hilu was difficult to saw in cats. The signal margin cord was not observed in dogs, but was present in all adult cats and possibly some kittens. The adrenal gland of the kittens was visualized as diffuse hypoechogenic and in adult cat was possible to saw the distinction of cortical and medullar region on the adrenal gland. Finaly, it's necessary to have a solid knowlodge about the topographic anatomy, image formation and normal standard in each specie for ultrasonografic exams. / Mestre

Educación que brinda la enfermera al alta hospitalaria a padres de niños posoperados de cirugía abdominal en un hospital local Chiclayo, 2018

Chachapoyas Martinez, Guadalupe Elena January 2020 (has links)
La investigación educación que brinda la enfermera al alta hospitalaria a padres de niños posoperados de cirugía abdominal en un hospital local Chiclayo, 2018. La Educación para el alta es una actividad básica de cuidados, dirigida a propiciar información necesaria sobre los cuidados en casa, esta actividad disminuye las complicaciones de la herida posoperatoria. La investigación Fue de tipo cualitativo, con un abordaje metodológico de estudio de caso, tuvo como objetivos: describir y analizar cómo es la educación que brinda la enfermera al alta hospitalaria a padres de niños posoperados de cirugía abdominal. Se utilizó la entrevista semi-estructurada como técnica de recolección de datos, como instrumento la guía de entrevista con preguntas abiertas a profundidad. Los sujetos de investigación fueron 12 padres de niños que fueron operados de cirugía abdominal, quienes cumplían con los criterios de inclusión. El análisis de los datos se realizó mediante el análisis de contenido temático, emergiendo de esta manera dos grandes categorías: (1) condicionantes de la educación para el alta hospitalaria, (2) limitantes para la educación en el alta hospitalaria. Además, durante el desarrollo de la investigación se consideró y respetó los principios éticos y de rigor científico. Concluyendo que las enfermeras reconocen que al impartir educación a los padres, carecen de protocolos; así mismo los padres conceptualizan la educación como rápidas, carente de información detallada y de material educativo. Los padres también experimentan la falta de personal de enfermería y la incomodidad en el ambiente donde reciben la educación.

Análise da qualidade de vida de pacientes submetidos a abdominoplastia circunferencial após tratamento cirúrgico da obesidade mórbida / Quality of life analysis in patients submitted to circumferential abdominoplasty after surgical treatment of the morbid obesity

Cintra Júnior, Wilson 05 June 2006 (has links)
INTRODUÇÃO: Os pacientes portadores de obesidade mórbida submetidos a tratamento cirúrgico para obesidade através de cirurgias desabsortivas-restritivas, após considerável perda de peso, podem apresentar excessos dermogordurosos nas várias regiões do corpo, freqüentemente associados à dificuldade de higiene pessoal e deambulação, maior incidência de infecções cutâneas, insatisfação com a imagem corporal, piora na auto-estima e nos relacionamentos profissionais e afetivos, além da piora da qualidade de vida. Naqueles pacientes com excessos dermogordurosos em abdome e flancos, e ptose da região glútea, a abdominoplastia circunferencial tem demonstrado ser uma solução cirúrgica eficaz. OBJETIVO: Avaliar as alterações na qualidade de vida dos pacientes submetidos a abdominoplastia circunferencial, nos aspectos afetivo-relacional, profissional, social e orgânico. MÉTODOS: Dezesseis pacientes do sexo feminino, que realizaram abdominoplastia circunferencial entre agosto de 2000 e janeiro de 2005, e eram acompanhadas no ambulatório de Cirurgia Plástica da Divisão de Cirurgia Plástica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, foram submetidas à entrevistas psicológicas semidirigidas, que consistiram de 31 questões, cujas respostas obtidas foram tabuladas e divididas em categorias. Utilizando-se a Escala Diagnóstica Adaptativa Operacionalizada (EDAO), e tendo como princípio norteador o critério adaptativo, as respostas foram classificadas como adequadas, pouco adequadas ou pouquíssimo adequadas. Através de notas atribuídas a cada resposta, foi possível a avaliação quantitativa nos quatro setores de funcionamento (afetivo-relacional, produtividade, sócio-cultural e orgânico) e a classificação diagnóstica das pacientes quanto à adequação. RESULTADOS: No setor afetivo-relacional, dez pacientes (62,5%) apresentaram respostas adequadas e cinco (31,25%), pouco adequadas. No setor produtividade, dez pacientes (62,5%) apresentaram respostas adequadas e quatro (25%), pouco adequadas. No setor sócio-cultural, treze pacientes (81,25%) apresentaram respostas adequadas. No setor orgânico, dez pacientes (62,5%) apresentaram valores máximos em todos os indicadores avaliados. Sete pacientes (43,75%) apresentaram adaptação eficaz e seis (37,5%), ineficaz leve. CONCLUSÕES: As análises, qualitativas e quantitativas, realizadas através da EDAO, concluiram que houve benefício efetivo aos pacientes submetidos a abdominoplastia circunferencial, nos aspectos físico, profissional, social e orgânico. / INTRODUCTION: Morbid obesity patients submitted to surgical treatment through disabsorptive/restrictive procedures, after considerable weight loss, may present skin and fat excess throughout different body regions, frequently associated with restrictions on personal hygiene and deambulation, greater incidence of skin infections, body image dissatisfaction, worsening of self-steem and of professional and affective relationships, besides down grading quality of life in general. On those patients that present skin and fat excess on the abdomen, flanks and gluteal ptosis, the circumferential abdominoplasty has demonstrated to be an effective surgical solution. OBJECTIVE: To evaluate the modifications on the quality of life of patients that underwent circumferential abdominoplasty on affective/relational, professional, social and organic aspects. METHODS: Sixteen female patients that underwent circumferential abdominoplasty between August 2000 and January 2005 were followed on the outpatient clinic of the Plastic Surgery Division of the Hospital das Clínicas of the University of São Paulo, and were submitted to semi-directed psychological interviews that consisted in 31 questions whose answers were tabulated and separated in categories. One used the Operational Adaptive Diagnostic Scale (OADS) and observing the adaptive patterns as the main criterion, the answers were classified as fairly, poorly and least poorly adequate. Through grades attributed to each answer, it was possible to evaluate quantitatively the four aspects of observation (affective/relational, professional, social and organic) and to establish a classification of the patients relative to their adaptive adequacy. RESULTS: On the aspect affective/relational, ten patients (62.5%) presented fairly adequate answers and five (31.25%) poorly adequate ones. On the productivity aspect, 10 patients (62.5%) presented fairly adequate answers and four (25%) poorly adequate ones. On the social/cultural aspect, 13 patients (81.25%) presented fairly adequate answers. On the organic aspect, 10 patients (62.5%) presented maximum grades in all evaluated criteria. Seven patients (43.75%) presented effective adaptation and six (37.5%) slightly ineffective. CONCLUSIONS: The qualitatively and quantitatively analysis made through OADS showed that there was effective benefit to the patients submitted to circumferential abdominoplasty on the physical, professional, social and organic aspects.
