Thoraxschmerzen bei Kindern und Jugendlichen - das Herz?

Chest pain in children and adolescents is a frequent observation, although potentially relevant disease is rather rare and then found in situations with acute presentation. In children with an inflammatory/infectious clinical context the differential diagnosis is oesophagitis, pleuropneumonia or pericarditis. Potentially dangerous complications may be found in youth with predisposing conditions for aortic dissection, pneumothorax or pulmonary embolism, or even in rare instances for an acute coronary complication. In these cases aggressive diagnostic work-up is mandatory. In the frequent elective outpatient evaluation of teenagers with long-lasting episodes of chest pain, relevant underlying cardiovascular disease only rarely can be found as the cause. In the elective outpatient evaluation for chest pain, usually patient history and clinical examination may be enough to track the problem, the main role of the physician is to provide reassurance with minimal but appropriate testing.

Biphosphonate-associated osteonecrosis of the maxilla. Case report and review of the literature

In recent years, a growing number of reports in the literature have linked osteonecrosis of the jaw bones with intravenously administered bisphosphonates prescribed for the treatment of hypercalcemia of malignancy due to bone lesions of multiple myeloma or bone metastases in patients with breast or prostate cancer. Furthermore, an association between chronic oral bisphosphonate use in patients with osteoporosis or Paget's disease, and bone necrosis in the mandible or maxilla has been demonstrated in numerous case reports and case series in the last couple of years. Therapeutically, osteonecrosis of the jaws seems to be difficult to treat surgically, often resulting in a recurring or even progressing lesion. In the present case report of a bisphosphonate-associated osteonecrosis of the maxilla in a patient with osteoporosis, the current literature will be discussed, and open research questions and potential problems for our daily dental practice routine will be addressed.

Monitoring eines Hundes mit traumatischem Hämoabdomen durch serielle Messung von abdominalem und peripher venösem Hämatokrit

Objective: This case report describes the use of serial measurements of peripheral venous and abdominal fluid hematocrits as a guide to treatment in a dog with traumatic hemoabdomen. Material and methods: An 18-month-old, female mixed-breed dog was presented with traumatic hemoabdomen. The dog was treated with intravenous fluids, and concurrent measurements of venous and abdominal fluid hematocrits were performed. Results: The initial hematocrit values were 39% in venous blood and 42% in abdominal fluid. Following fluid therapy, the venous hematocrit decreased to 20%, whereas the abdominal hematocrit remained stable at 40%. Based on this finding severe ongoing intra-abdominal hemorrhage was ruled out, and the dog was treated conservatively. Conclusion and clinical relevance: Comparison of serial abdominal and venous hematocrits may be useful in assessing the need for surgical management in patients with traumatic hemoabdomen.

Transdisziplinäre Forschung weiterentwicklen: Eine Synthese mit 15 Empfehlungen

Inter- und Transdisziplinarität erfährt in Lehre und Forschung heutzutage eine vielversprechende Entwicklung, nicht nur im Schweizer Hochschulsystem, sondern auch auf europäischer und globaler Ebene. Sollen die Probleme unserer Zeit adäquat verstanden, analysiert und schliesslich gelöst werden, ist es unabdingbar, die disziplinären Kompetenzen in einen konstruktiven Austauschprozess und Dialog zu bringen. Die Behandlung unserer komplexen, menschlichen, sozialen, politischen und die Umwelt betreffenden Probleme drängt zunehmend auf die Durchlässigkeit des disziplinären Wissens und Wissenssystems. Dieses Buch richtet sich an all jene, die sich in ihrer täglichen Arbeit in Lehre, Forschung oder Studium mit komplexen Fragenstellungen beschäftigen und sich dabei nicht auf die Reduktion auf eine einzelne Disziplin beschränken können. Es zeigt den aktuellen Stand der inter- und transdisziplinären Lehre und Forschung in der Schweiz auf. Schwerpunkt liegt bei der Präsentation von erfolgreichen Projekten, ihren konzeptuellen, theoretischen und methodologischen Grundlagen sowie den daraus gewonnenen Erfahrungen.
