[The working time load of specialists and senior physicians in German urology-a critical assessment]. / Die Arbeitszeitbelastung von Fach- und Oberärzten in der deutschen Urologie ­ eine Bestandsaufnahme.

BACKGROUND: The working and continued training conditions of assistant physicians in urology in Germany have already been analyzed. But what about senior urologists in Germany? Under which conditions do they have to work? As far as we know no published data currently exist which illuminate the conditions of this special urological professional group, therefore, the results of this survey are presented. OBJECTIVE: To survey and evaluate the current working conditions of certified and senior urologists in Germany as comprehensively as possible. MATERIAL AND METHODS: The working group of employed physicians of the Professional Association of German Urologists (BvDU) carried out a survey within the framework of the urological senior physician forum 2016 and on-line via the e­mail distributor of the German Society for Urology (DGU). The questions involved the workload, working conditions and satisfaction, overtime performed, working hours and opt out regulations. RESULTS: A total of 176 senior physicians participated in the survey of which 88% were male and 12% female. In Germany there are 1125 senior physicians. The average age of the responders was 44.9 years. In more than 80% of the participants the average weekly working hours were over 50 h and 70% signed an opt out regulation. An association between an increasing job dissatisfaction above a working week over 55 h and an average attendance in on-call service over 4 h could be established. The number of on-call services had no influence on job satisfaction. A total of 43% (70 out of 162) of the participants stated that overtime hours were regularly forfeited and 12% (20 out of 162) that all overtime hours were forfeited. Approximately 30% of senior physicians in German urology were dissatisfied with the current working conditions in the present form. CONCLUSION: Based on the acquired data, adaptation and improvements in the working conditions of senior urologists are necessary in order to maintain the attractiveness of the occupational image and leading positions in German urology.

Analysis of computer-aided techniques for virtual planning in nasoalveolar moulding.

We compared two methods of planning virtual alveolar moulding as the first step in nasoalveolar moulding to provide the basis for an automated process to fabricate nasoalveolar moulding appliances by using computer-assisted design and computer-aided manufacturing (CAD/CAM). First, the initial intraoral casts taken from seven newborn babies with complete unilateral cleft lip and palate were digitised. This was repeated for the target models after conventional nasoalveolar moulding had been completed. The initial digital model for each patient was then virtually modified by two different modelling techniques to achieve the corresponding target model: parametric and freeform modelling with the software Geomagic(®). The digitally-remodelled casts were quantitatively compared with the actual target model for each patient, and the comparison between the two modified models and the target model showed that freeform modelling of the initial cast was successful (mean (SD) deviation n=7, +0.723 (0.148) to -0.694 (0.157)mm) but needed continuous orientation and was difficult to automate. The results from the parametric modelling (mean (SD) deviation, n=7, +1.168 (0.185) to -1.067 (0.221)mm) were not as good as those from freeform modelling. During parametric modelling, we found some irregularities on the surface, and transverse growth of the maxilla was not accounted for. However, this method seems to be the right one as far as automation is concerned. In addition, an external algorithm must be implemented because the function of the commercial software is limited.

The nature, frequency and course of psychiatric disorders in the first year after traumatic brain injury: a prospective study.

BACKGROUND: Psychiatric disorders are common following traumatic brain injury (TBI). However, few studies have examined the course of disorder development and the influence of pre-injury psychiatric history. The present study aimed to examine the frequency of, and association between, psychiatric disorders occurring pre- and post-injury, and to examine the post-injury course of disorders. METHOD: Participants were 102 adults (75.5% male) with predominantly moderate-severe TBI. Participants were initially assessed for pre-injury and current disorders, and reassessed at 3, 6 and 12 months post-injury using the Structured Clinical Interview for DSM-IV Disorders (SCID). RESULTS: Over half of the participants had a pre-injury psychiatric disorder; predominantly substance use, mood, and anxiety disorders. In the first year post-injury, 60.8% of participants had a psychiatric disorder, commonly anxiety and mood disorders. Post-injury disorders were associated with the presence of a pre-injury history (p<0.01), with 74.5% of participants with a pre-injury psychiatric history experiencing a post-injury disorder, which commonly presented at initial assessment or in the first 6 months. However, 45.8% of participants without a pre-injury history developed a novel post-injury disorder, which was less likely to emerge at the initial assessment and generally developed later in the year. CONCLUSIONS: Despite evidence that most post-injury psychiatric disorders represent the continuation of pre-existing disorders, a significant number of participants developed novel psychiatric disorders. This study demonstrates that the timing of onset may differ according to pre-injury history. There seem to be different trajectories for anxiety and depressive disorders. This research has important implications for identifying the time individuals are most at risk of psychiatric disorders post-injury.
