A case of chylothorax treated curatively with Sapylin, a streptococcus preparation

Chylothorax is an uncommon disease where fatty fluid accumulates within the chest cavity. Conservative management, including repeated thoracentesis or pleurodesis, seems to be suitable to most cases. Herein, we present a case of efficacious pleurodesis by intrapleural injection of Sapylin, a streptococcus preparation, for the treatment of chylothorax. A 52-year-old non-smoking female farmer was diagnosed as idiopathic chylothorax after we ruled out possible causes including chest trauma, lymphoma, lung cancer, filariasis, tuberculosis, and etc. Two-time intra-thoracic injection of 3 Klinische Einheit （KE） Sapylin achieved rapid and effective control of chylothorax with no severe side effects. Sapylin may facilitate pleurodesis by producing a strong inflammatory response.

As the climate changes: Intergenerational action-based learning in relation to flood education

It is a concern that children represent an under-researched group in flood education and preparedness because as adults they are more likely to experience flooding as the climate changes, and because it suggests their potential today, as agents of change, is being undervalued. Using action-based, participatory methodology with seven to nine-year-old children, a creative and inclusive flood education resource was developed as a stimulus for learning. Evaluation revealed that young children can learn about flooding and preparedness, and that intergenerational learning from child to parent can also occur, with children transferring the messages learned in school to home. However, thematic analysis suggests key factors such as family relationships (empowerment of children) and the parents’ disconnection and dissociation from risk limit the success of intergenerational learning. The implications of these in relation to flood education, flood preparedness, and household resilience levels are explored.     

The dimensional accuracy of preparation of femoral cavity in cementless total hip arthroplasty

Objective: To observe the accuracy of femoral preparation and the position of the cementless prosthesis in femoral cavity, and to compare the results between the computer-assisted surgical group (CASPAR) and the conventional group. Methods: Ten femoral components were implanted either manually or by CASPAR in cadaver femurs. The specimens were cut to 3 mm thick slices. Microradiograms of every slice were sent to a computer for analysis with special software (IDL). The gaps and the medullary cavities between component and bone, the direct bone contact area of the implant surface, the gap width and the percentage of gap and bone contact area were measured in every slice. Results: In the proximal implant coated with HA of the CASPAR group, the average percentage of bone contact reached 93.2% (ranging from 87.6% to 99.7%); the average gap percentage was 2.9% (ranging from 0.3% to 7.8%); the maximum gap width was 0.81 mm and the average gap width was only 0.20 mm. While in the conventional group, the average     

Preparing ‘educational’ leaders in managerialist times: an Australian story

The preparation of educational leaders is a global phenomenon. Education systems have developed numerous means by which current and aspiring leaders are prepared for the role. Through the example of a large public school system in Australia, this paper argues that the doxa of school leadership establishes a particular identity of the principalship. One which constructs the principal as the deliverer of state initiated reforms. Theoretically informed by Bourdieu, this paper argues for an alternate way of thinking about leadership preparation, one based on introducing participants to the conversation of the world.
