Enfisema subcutáneo durante tratamiento restaurador: caso clínico
2006
El enfisema subcutáneo es una complicación poco frecuente en la práctica odontológica, que ha ido en aumento debido al uso de instrumentos con aire a presión. Muchos de los casos no son reconocidos o presentan un diagnóstico errado. La mayor parte de los pacientes con esta complicación presentan resolución espontánea, sin embargo algunos pueden evolucionar con complicaciones que ponen en peligro la vida. Aquí presentamos un caso de enfisema subcutáneo ocurrido durante un procedimiento restaurador de rutina. El diagnóstico diferencial y el manejo de esta condición son discutidos. Subcutaneous emphysema is a relatively rare complication of dental treatment, although increasingly due to the us…

Reformatierungen als Lösungsansatz für die Problematik der unterschiedlichen Schichtführung beim Vergleich von3He-MRT und HR-CT der Lunge
2003
Purpose: 3 He-MRI of the lung has been shown to be a sensitive method for functional imaging of the lung. A previous study compared 3 He-MRI (coronal planes) with CT (transverse planes) by looking for ventilation defects and their pathomorphologic correlation. Anatomic structures, such as lobar fissures and hilar vessels, were used for orientation, but the reliable assignment of ventilation defects to lung segments is problematic. The present work compares multiplanar reformations of 3 He-MRI and HR-CT, which were generated from planes determined by the respective method, and investigates their suitability as a solution of this problem. Materials and Methods: A total of 16 data sets taken f…
The treatments of pursiness in the ancient time
2009
The pursiness is a very old disease known since antiquity whose name comes from the fact that affected horse have difficulties to expirate air and produce a movement of forced expiration to expel air. This symptom is now mainly related to pulmonary emphysema. Treatments remained generally the same from antiquity to the nineteenth century. They used mainly bleeding and therapeutic mixtures supposed to work on the lung. The revolution was to come in the nineteenth century with the use of arsenic.
Was heißt wie? Ansatz und Glossar zu Befundung und Verständnis in der HRCT der Lunge
1996
In HRCT reports multiple different, often synonymous, German and English terms are used. The variety of terms impede understanding and acceptance of HRCT. Purpose of this paper is to present a scheme, which is based on the anatomic landmarks (secondary lobule), and the density of pathologic changes, as well as a glossary from the German HRCT-literature, including suitable terms, definitions, synonyms and English terms. Low attenuation changes include emphysemas, air-filled cavities (bullae, cysts, cavitations, honeycombing) and bronchial dilatation, changes with increased density consist of diffuse (ground glass opacity, consolidation) and focal processes (reticular and nodular densities). …
The difference in risk of chronic pulmonary disease morbidity and mortality between elite athletes and ordinary men in Finland
2020
Introduction: The impact of a history of competitive sports on later smoking behavior and occurrence of chronic pulmonary diseases is poorly known. We investigated how a history of elite level sports predicted later pulmonary disease morbidity and mortality. Methods: Chronic pulmonary disease incidence were assessed from national hospital and cause-of-death registers from 1970 to 2015 among Finnish male former elite athletes (n=2078) and matched controls (n=1453) alive in 1970 (mean age 45.0 years). Hazard ratios (HRs) were calculated by Cox proportional hazards model. In 1985, cohort members reported on their smoking habits, engagement in physical activity/sports and physician-diagnosed ch…
Quantification and Characterization of Pulmonary Emphysema in Multislice-CT
2003
The new technology of the Multislice-CT provides volume data sets with approximately isotropic resolution, which permits a non invasive measurement of diffuse lung diseases like emphysema in the 3D space. The aim of our project is the development of a full automatic 3D CAD (Computer Aided Diagnosis) software tool for detection, quantification and characterization of emphysema in a thoracic CT data set. It should supply independently an analysis of an image data set to support the physician in clinical daily routine. In this paper we describe the developed 3D algorithms for the segmentation of the tracheo-bronchial tree, the lungs and the emphysema regions. We present different emphysema des…
Repräsentiert der HRCT-Emphysemindex die gesamte Lunge?
2005
Purpose: Comparison of emphysema index derived of thin section MD-CT of the entire lung volume and HRCT, simulated by calculation of every twentieth image of the whole data-set. Materials and Methods: Pulmonary emphysema was quantified by semiautomatic, segmentation of lung borders and assessment of lung volume and emphysema volume within these borders. The emphysema index (pixel index) was calculated. Statistical analysis was done by the sign-test and Bland-Altman-analysis. Results: Median lung volume, emphysema volume and emphysema index are significantly higher in simulated HRCT. Median lung volume (emphysema volume) calculated by HRCT is 5118 ml (407 ml) and 5040 ml (367 ml) calculated …
Gastrointestinal perforation: ultrasonographic diagnosis.
2013
Abstract Gastrointestinal tract perforations can occur for various causes such as peptic ulcer, inflammatory disease, blunt or penetrating trauma, iatrogenic factors, foreign body or a neoplasm that require an early recognition and, often, a surgical treatment. Ultrasonography could be useful as an initial diagnostic test to determine, in various cases the presence and, sometimes, the cause of the pneumoperitoneum. The main sonographic sign of perforation is free intraperitoneal air, resulting in an increased echogenicity of a peritoneal stripe associated with multiple reflection artifacts and characteristic comet-tail appearance. It is best detected using linear probes in the right upper q…
