Hydatid disease has characteristic imaging features on CT, which allow accurate preoperative diagnosis in most cases. However, when it occurs at unusual locations the diagnosis is often difficult, especially as the imaging appearance varies at different sites. In this article we have presented a pictorial review of the CT features of disease due to Echinococcus granulosus at various sites in the human body. 相似文献

Summary We report a case of a male patient suffering from a severe hemorrhagic radiation proctitis which gradually ceased with hyperbaric oxygen. We discuss the mechanisms of chronic radiation injury and the effect of the hyperbaric oxygen. This therapy is proposed as an alternative to surgical intervention for this abnormality. 相似文献

We report respiratory obstruction following surgery in the sitting position with tracheal intubation and placement of a transesophageal echocardiography probe. Obstruction was due to pharyngeal oedema, which resolved with 24 hours. The mechanisms of this complication are discussed. 相似文献

The Occupational Stress Indicator (OSI) was translated into Brazilian Portuguese and administered to a sample of 84 white-collar workers in Brazil. Five of the six scales of the OSI (job satisfaction, mental and physical health, coping, type A behaviour, sources of stress) showed acceptable reliability. The reliability of the sixth scale (locus of control) was disappointing, in keeping with earlier findings that suggest that this scale requires further development. Alternative measures of the stress outcomes — job satisfaction, mental health and physical health — were taken in order to assess the construct validity of these three scales. These measures included translations of the Hackman-Oldham job satisfaction measure and the Crown–Crisp Experiential Index, as well as subjective measures of health-related behaviours. Correlational and multivariate analyses of these data suggested that the job satisfaction, mental health and physical health scales of the OSI had good validity, with the physical health measure probably including a psychosomatic component. These findings are promising for the development of a new version of the OSI designed for use in South America. 相似文献

The skeletal dysplasias are a clinically and genetically heterogeneous group of conditions affecting the development of the osseous skeleton and fall into the category of rare genetic diseases in which the diagnosis can be difficult for the nonexpert. Two such diseases are pseudoachondroplasia (PSACH) and multiple epiphyseal dysplasia (MED), which result in varying degrees of short stature, joint pain and stiffness and often resulting in early onset osteoarthritis. PSACH and some forms of MED result from mutations in the cartilage oligomeric matrix protein (COMP) gene and to aid the clinical diagnosis and counselling of patients with a suspected diagnosis of PSACH or MED, we developed an efficient and accurate molecular diagnostic service for the COMP gene. In a 36-month period, 100 families were screened for a mutation in COMP and we identified disease-causing mutations in 78% of PSACH families and 36% of MED families. Furthermore, in several of these families, the identification of a disease-causing mutation provided information that was immediately used to direct reproductive decision-making. 相似文献
