Due to the increased survival of patients with pulmonary hypertension, even non-cardiac anesthesiologists will see these patients more frequently for anesthesia. The hemodynamic goal in the perioperative period is to avoid an increase in pulmonary vascular resistance (PVR) and to reduce a possibly pre-existing elevated PVR. Acute increases of chronically elevated PVR may result from hypoxia, hypercapnia, acidosis, hypothermia, elevated sympathetic output and also release of endogenous or application of exogenous pulmonary vasoconstrictors. ⋯ Drug interventions to perioperatively reduce PVR include administration of pulmonary vasodilators, such as oxygen, prostacyclines (epoprostenol, iloprost), phosphodiesterase III (milrinone) and V (sildenafil) inhibitors, as well as nitrates and nitric oxide. Along with the concept of selective pulmonary vasodilation inhalative administration of pulmonary vasodilators has benefits compared to intravenous administration. New therapeutic strategies, such as inhalational iloprost, inhalational milrinone and intravenous sildenafil can be introduced without significant technical support even in smaller departments.

The amendment to the higher education act ("Hochschulrahmengesetz") of 1998 postulates an evaluation of teaching for quality assurance. Hence, in the winter semester of 2004 the University Medical Center of Bonn introduced a semester questionnaire for students to evaluate the quality of teaching (EVALON). This evaluation is designed to be an objective benchmarking tool which is used for the distribution of university funds. It is also a steering instrument for direct improvement of teaching in clinical subjects. The aim of this study was to investigate, whether EVALON improved the quality of teaching between 2006 and 2010 and whether the department of anesthesiology improved its ranking in comparison with the other participating institutes. ⋯ The reorganization of teaching anesthesiology, directly controlled by the results of EVALON improved the ranking of the department of anesthesiology. There was also a concomitant increase of the performance-oriented allocation of funds assigned to the department of anesthesiology based on the EVALON results.

Anesthesiologists have a well-known increased risk of substance abuse including the intravenous administration of opioids and propofol. However, katamnestic reports from the point of view of propofol-addicted anesthesiologists themselves are missing which would aid a better understanding of the dynamics and progress of addiction. ⋯ This case shows exemplarily in accordance with the current literature that warning signs in addicted physicians are often ignored by colleagues and supervisors and rehabilitation is possible under professional therapy and continuous surveillance. Additionally, this case emphasizes the necessity of controlling the distribution of propofol to reduce the life-threatening professional risk to anesthesiologists.

[Tuberculous encephalitis, Landouzy sepsis and Pott's disease: complications after surgery for spinal stenosis].
Tuberculosis is an infectious disease with a decreasing incidence in Germany. In particular, the occurrence of reinfections and possible complications associated with this disease, such as tuberculous meningitis/encephalitis and Landouzy sepsis are rare in industrial countries. ⋯ Additionally, the patient developed sepsis and meningitis. At this time an infection with Mycobacterium tuberculosis could be detected in both cerebrospinal fluid and abscess material of the spine suggesting a Landouzy sepsis, tuberculous meningitis/encephalitis and the suspicion of an underlying Pott's disease.
