[Promoting young academics in anesthesiology: factors for an attractive internship]. / Nachwuchsförderung in der Anästhesiologie: attraktive Gestaltung der Famulatur.

BACKGROUND: Practical experiences in clinical traineeships can shape the later specialty choice of medical students. KEY QUESTION: The following study aimed to find factors in anesthesiological clinical traineeship that encourage students to specialize in the field. MATERIAL AND METHODS: As part of a nationwide online survey conducted by the working group for education of the German Association for Orthopedics and Trauma Surgery (Deutsche Gesellschaft für Orthopädie und Unfallchirurgie, DGOU), study participants (n = 479) answered questions about their minimum 4­week traineeship in anesthesiology. The information on items was analyzed in six content categories: 1) integration into the team, 2) acquisition of skills, 3) teachers, 4) quality of teaching, 5) structure of teaching and 6) satisfaction with the clinical internship. The respondents were subdivided into 4 groups by answering the question "Could you imagine an elective in anesthesiology during the final year (PJ)" with "Yes, I have made this decision after the clinical traineeship" (JdF, n = 212, 44%), "No I have decided against an elective during the final year after the traineeship" (NdF, n = 56, 12%), "Yes I have decided for an elective in anesthesiology before the internship" (JvF Yes: n = 144, 30%) and "No, I have decided against an elective in anesthesiology before the internship" (NvF: n = 67, 14%). Answers of the participants regarding the six content categories were compared between the four groups. RESULTS: The survey reached all medical faculties in Germany and included participants with an average age of 25.8 years and a balanced gender ratio. There were significant differences between satisfied and dissatisfied students in all four subgroups. Of the 479 respondents, 211 (44%) were already set regarding their decision of choosing anesthesiology as an elective during the final year before the clinical traineeship. Of the respondents 268 (56%) were influenced by the internship, 212 (44%) of them positively. In total, 81% of the trainees rated the internship as "satisfying". Students who were satisfied with the overall internship and who spoke in favor of the PJ elective in anesthesiology differed significantly from the other groups in the categories of team integration, skills acquisition, structure and quality of teaching. The teaching of practical skills and specialist knowledge as well as the integration into diagnostics and treatment planning promoted the recruitment of young people. DISCUSSION: The positively evaluated anesthesiology internship promotes later specialty choice, with quality and structure of the teaching affecting student satisfaction. Trainees who were attracted by anesthesiology gave better overall ratings and acquired more skills during the course of the internship. In order to win aspiring doctors for anesthesiology, the medical team has to integrate trainees well and support the acquisition of practical skills and specialist knowledge. In addition, didactics and practical relevance should be given high priority.

[Informed consent for surgery: clearly regulated by the patient rights law-significant uncertainty among medical students : Legal analysis and inventory of over 2500 medical students in Berlin as part of the Progress Test Medicine]. / Chirurgische Aufklärung: Klar geregelt durch das Patientenrechtegesetz ­ deutliche Unsicherheit bei Medizinstudierenden : Rechtsanalyse und Bestandsaufnahme bei über 2500 Berliner Medizinstudierenden im Rahmen des Progress Test Medizin.

BACKGROUND: Obtaining informed consent is a challenging task and is part of the educational objectives in the German NKLM. Teaching formats are inconsistent and time-consuming, with little emphasis on legal aspects, although they have moved into the focus of attention since the implementation of patient rights laws and play an important role in legal proceedings. OBJECTIVES: The aim of this study was the evaluation of medical students' knowledge about the legal aspects of obtaining informed consent. A legal analysis was performed, and the patient rights laws were reviewed with reference to implications for undergraduate medical education. MATERIALS AND METHODS: After the analysis of laws and jurisdiction, multiple-choice questions regarding the legal aspects of obtaining informed consent were created and placed in the Progress Test Medicine (PTM). A statistical analysis of the results of Berlin medical students was performed descriptively. RESULTS: The answers of 2625 (winter semester 2018/19) and 2409 (summer semester 2019) medical students in Berlin were analyzed. The rate of students who answered the questions about the procedures requiring informed consent and adequate time for consideration increased over time but did not reach comparable values to all PTM questions. Questions about required content were answered correctly by 30 to 60% of the students, regardless of their level of training; we did not see an increase along with the time of study. CONCLUSION: In our study, we were able to show that medical students of all educational levels show tentativeness when it comes to the legal aspects of obtaining informed consent. Yet, the legal framework offers room for new teaching formats like "Co-Action", introduced in this paper for the first time, where students acquire informed consent while being supervised by the medical doctor in charge.

[Physician Shortage: How to Prevent Generation Y From Staying Away - Results of a Nationwide Survey]. / Ärztemangel: Was tun, bevor Generation Y ausbleibt? Ergebnisse einer bundesweiten Befragung.

BACKGROUND: Medical students' attitudes and expectations about their future working life are changing. To hire the best talents from Generation Y, hospitals must pay attention to these factors to make working in patient care more attractive. However, little detailed knowledge about the professional and career expectations of today's medical students is available to date. METHOD: In a nationwide online survey, a total of 9079 medical students from all German medical faculties returned the questionnaire. Twenty-one questions related to future career choices and work satisfaction, followed by 21 questions dealing with reasons for not working in patient care. RESULTS: Factor analysis yielded five factors: work-life balance, career, professional needs, working atmosphere, and prestige. A correlation analysis between these factors and respondents' socio-demographic data revealed significant correlations with sex, specialty choice, and marital/parental status. A correlation analysis with "reasons for not working in patient care" revealed that work-life balance, career, professional needs, and working atmosphere had high priority for both sexes. DISCUSSION: It is crucial to collect data on the work satisfaction of Generation Y, whose members are motivated and willing to perform in today's highly demanding work environment. However, sex-dependent/independent expectations must be met to make the medical profession more attractive, to overcome the Germany-wide shortage of physicians, and to attract young doctors to the hospitals.

Utility of near infrared light to determine tissue oxygenation during hepato-biliary surgery.

Near-infrared spectrophotometry assesses cerebral oxygen saturation (ScO2) based on the absorption spectra of oxygenated and deoxygenated hemoglobin, and the translucency of biological tissue, in the near-infrared band. There is increasing evidence that optimising cerebral oxygenation, guided by ScO2, is associated with improved outcomes in a variety of high risk surgical settings. However, in patients with liver disease, bilirubin can potentially render cerebral oximetry inaccurate. As a result, measurement of cerebral oxygen saturation is rarely undertaken in patients undergoing hepatobiliary surgery. We prospectively measured baseline and intraoperative cerebral oxygen saturation in patients undergoing major pancreatic surgery. Indices including bilirubin, sodium, platelets and maximum amplitude on thromboelastography were associated with low baseline ScO2. However, those patients with low ScO2 (≤51%) maintained a similar trend in cerebral oximetry values both at induction and intraoperatively to those with a normal ScO2. We conclude that the pattern of cerebral oximetry is similar in patients undergoing major pancreatic surgery regardless of their underlying liver dysfunction. Therefore, cerebral oximetry may have a role in monitoring neurological function in this high risk group of patients.

Predictors of outcome in decompensated liver disease: validation of the SOFA-L score.

A growing number of patients with liver disease are being referred for critical care support. We have recently shown that a combination of lactate and SOFA score (SOFA-L score) may provide an accurate, objective measurement of prognosis in a group of patients admitted to ICU with alcoholic liver disease. This score has not been validated in an independent patient cohort. A retrospective study was performed where patients admitted to our ICU with decompensated liver disease (any cause) were included. The SOFA-L score accurately predicted in-hospital mortality in this group of patients with an area under the ROC curve of 0.83. Sensitivity and specificity were 65% and 87% respectively SOFA-L performed superior to SOFA, MELD and MELD-Na scores. This study validates the use of the SOFA-L score in the initial 24 hours of ICU admission as an accurate predictor of mortality in this group of patients with a high mortality.

[Protect employability: effects of prevention programs offered by the German pension scheme]. / Beschäftigungsfähigkeit teilhabeorientiert sichern (Betsi): Ergebnisse der Einjahreskatamnese von Prävention-s-maßnahmen der Deutschen Rentenversicherung.

A pilot study was carried out in 4 medical rehabilitation centers to examine the practicability and effectiveness of preventive life-style interventions for employees with risk factors. The programs were developed in cooperation with the German pension scheme and employers. Selection criteria were risk factors as lack of physical activity, overweight, dorsal pain or job strain. The results demonstrate that preventive programs, which are conducted in addition to the normal working hours on the job, can be implemented successfully in rehabilitation units. The participation in the multimodal prevention program goes along with a stable reduction of risky health behavior: increased physical activity, stress coping, dietary change und weight reduction. The healthier life-style is reflected in an enhanced state of health and has also positive impact on the occupational field scale: The percentage of employees who believed to be able to work until their old-age pension, could be increased significantly (p<0.001) from 47% to 74%. Work-related risk behaviors like excessive demands on oneself were reduced and protective strategies were -developed.

Attitudes and intentions of current anaesthetic trainees.

We report the results of a survey of Irish anaesthetic specialist trainees to establish their future training intentions, their interest in seeking a Consultant position in Ireland and identification of factors that may reduce the attractiveness of future employment in the HSE. 149 responses were received (71% of trainees). 137 (92%) are likely to complete further training abroad, but only 24 (16.1%) are definitely planning to return to work in Ireland. Factors, in order of importance that influence their return to Ireland include equivalence of all Consultants, salary level and availability of flexible work practices. Almost all (131 - 91%) would only consider working in Ireland at Consultant level. These results reveal that the current cohort of specialist trainees do not consider Ireland an attractive place to work, and any further diminution of the current Consultant grade will only serve to worsen this perception.

X-ray generation by fs-laser processing of biological material.

The use of ultrashort pulse lasers in medical treatments is increasing and is already an essential tool, particularly in the treatment of eyes, bones and skin. One of the main advantages of laser treatment is that it is fast and minimally invasive. Due to the interaction of ultrashort laser pulses with matter, X-rays can be generated during the laser ablation process. This is important not only for the safety of the patient, but also for the practitioner to ensure that the legally permissible dose is not exceeded. Although our results do not raise safety concerns for existing clinical applications, they might impact future developments at higher peak powers. In order to provide guidance to laser users in the medical field, this paper examines the X-ray emission spectra and dose of several biological materials and describes their dependence on the laser pulse energy.

An early botulinum toxin A treatment in subacute stroke patients may prevent a disabling finger flexor stiffness six months later: a randomized controlled trial.

OBJECTIVE: The study asked whether an early botulinum toxin A (BTX-A) injection in subacute stroke patients may prevent a disabling finger flexor stiffness six months later. DESIGN: Single-blind, randomized pilot study. SETTING: Inpatient rehabilitation centre. SUBJECTS: Eighteen stroke patients, interval 4-6 weeks, non-functional arm, Fugl-Meyer arm score (0-66) <20, beginning elevated finger flexor tone, randomly allocated to group A or B. INTERVENTIONS: In group A patients 150 units BTX-A (Xeomin) injected into the deep and superficial finger (100 units) and wrist flexors (50 units), no injection in group B patients. Comprehensive rehabilitation in both groups. MAIN MEASURES: Primary variable was the Modified Ashworth Scale score (0-5) of the finger flexors; secondary variables were whole arm muscle tone with REPAS (a summary rating scale for resistance to passive movement), its motor control with the Fugl-Meyer arm score, and a disability scale, blindly assessed at T0 (start), T1 (four weeks) and T6 (six months). RESULTS: Homogeneous groups at T0. Significantly less finger flexor stiffness in the BTX-A group at T1 and T6, the mean (SD) Modified Ashworth Scale scores in group A (B) were: 1.7 ± 0.5 (1.6 ± 0.5) at T0; 0.4 ± 0.5 (1.9 ± 0.7) at T1; and 1.4 ± 0.7 (2.4 ± 0.9) at T6. Among the secondary measures, the disability score, namely the items pain and passive nail trimming, was lower in group A at T1 and T6. CONCLUSIONS: The results indicate an effect of early BTX-A injection on finger flexor stiffness six months later, presumably attributable to a reduced contracture development. Effect size calculation suggests inclusion of at least 17 patients per group excluding drop-outs in a warranted placebo-controlled trial.

[DGRW-Update: musculo-skeletal diseases]. / DGRW-Update: Erkrankungen des Muskel-Skelettsystems.

BACKGROUND: Orthopedic rehabilitation is a major entity in rehabilitation. Due to coming demographic changes and its challenges concerning mobility of elderly patients it will increase. The criticism on orthopedic rehabilitation in Germany focuses on its missing evidence in therapeutic eff ectiveness especially in chronic low back pain. This overall-criticism is actually no more valid as there are a number of studies showing eff ectiveness of orthopedic treatment in rehabilitation if psychosocial comorbidities are respected and treatment is focussed on occupational training and eintegration. GOALS: This overview describes the actual situation in orthopedic rehabilitation and its research. RESULTS: The need for orthopedic rehabilitation will increase over the next years due to demographic changes. Important fi elds in orthopedic rehabilitation research are chronic low back pain, new rehabilitation models with focus on occupational reintegration, rehabilitation in elderly and following joint surgery as well as the analysis of health-care-system changes due to disease related groups.

Renopathological Microstructure Visualization from Formalin Fixed Kidney Tissue by Matrix-Assisted Laser/Desorption Ionization-Time-of-Flight Mass Spectrometry Imaging.

Understanding early stage renal malfunctions with regard to the glomerular filtration processes is essential for nephropathological prescreening strategies and intervention at an early stage. Mass spectrometry imaging (MSI) in combination with histopathology can provide an universal analytical approach. Proteomic and lipidomic aspects of glomerular biocompositions were applied for micro-structural differentiation in healthy rat kidney samples. Usability of commonly used tissue embedding media and the compatibility of histological staining and fixation methods were of interest. It was demonstrated that ultra-thin tissue samples (500 nm, 1 and 10 µm) can be used for lipid and peptide-based differentiation at the glomerular resolution level in formalin-fixed tissue samples in combination with preceding histological staining for correlating optical and molecular mass images.

Epidural analgesia for labour: maternal knowledge, preferences and informed consent.

Epidural analgesia has become increasingly popular as a form of labour analgesia in Ireland. However obtaining true inform consent has always been difficult. Our study recruited 100 parturients who had undergone epidural analgesia for labour, aimed to determine the information they received prior to regional analgesia, and to ascertain their preferences regarding informed consent. Only 65 (65%) of patients planned to have an epidural. Knowledge of potential complications was variable and inaccurate, with less than 30 (30%) of women aware of the most common complications. Most women 79 (79%) believed that discomfort during labour affected their ability to provide informed consent, and believe consent should be taken prior to onset of labour (96, 96%). The results of this study helps define the standards of consent Irish patients expect for epidural analgesia during labour.

Mild topographic abnormalities that become more suspicious on Scheimpflug imaging.

PURPOSE: Although several screening methods exist, postoperative corneal ectasia after refractive surgery is a severe complication. One possibility for this might be the fact that screening methods may fail in detection of preoperative risk factors such as forme fruste keratoconus (FFKC). METHODS: Retrospective evaluation of four cases that showed only mild changes of FFKC on placido-based topography but revealed indicative findings on Scheimpflug imaging (Pentacam). RESULTS: While in placido-based topography evaluation of corneal topography did not show a clear FFKC, the evaluation of corneal topography on Scheimpflug imaging together with the data of spatial corneal thickness revealed distinctive FFKC in all cases presented. CONCLUSIONS: Although both methods bear the risk of not detecting pre-existing FFKC, Scheimpflug imaging seems superior to placido-based corneal topography alone.

[Visual rehabilitation in patients with hereditary retinal dystrophy: current data from a Low Vision Department]. / Visuelle Rehabilitation bei Patienten mit hereditärer Netzhautdystrophie: aktuelle Daten einer Sehbehindertenambulanz.

BACKGROUND: Especially during adolescence, hereditary retinal dystrophies can cause visual impairment. Because of their high mobility and working activities, these patients represent a great challenge for a Low-Vision Department. This study illustrates the spectrum of appropriate magnifying devices for them, as prescribed in our Low-Vision Department. PATIENTS AND METHODS: Between January 2003 and October 2004, we took care of 2,500 patients in our Low-Vision Department. 141 (5.6 %) of them suffered from a hereditary retinal dystrophy. After ascertaining the best corrected distance and near visual acuity as well as the magnification demand we prescribed the appropriate optic or electronic magnifying aids. RESULTS: The preferential age for the first visit was between 15 and 40 years. Within the retinal dystrophies we saw cone-rod dystrophy in 46 (33 %) patients, Stargardt's disease in 38 (27 %), retinitis pigmentosa in 37 (26 %), albinism in 15 (11 %) and achromatopsia in 5 (3 %) patients. The average of the best corrected distance visual acuities of the better eye was 0.142 (SD +/- 3.3 lines), the best corrected visual acuity for reading was 0.124 (SD +/- 6.1 lines). The average magnification demand was 5 x (SD +/- 6.7). The most prescribed optic magnifying aids were distance spectacles and magnifying glasses (each 20 %), monocular telescopes, contrast enhancing filters (each 13 %) and reading glasses (8 %). Electronic magnifying aids were prescribed in only 8 %. CONCLUSIONS: Fluent reading ability in hereditary retinal dystrophies could be achieved mostly by optic magnifying aids. The high proportion of prescribed distance glasses and magnifying glasses shows that often simple magnifying aids are suitable for these patients. Because of the high photophobia, contrast-enhancing filters should always be considered.

[Measurement of the central corneal power after myopic LASIK]. / Evaluation der zentralen Hornhautbrechkraft nach myoper LASIK.

PURPOSE: Comparison of the central corneal refractive power before and after myopic LASIK using the Keratograph and the Pentacam. The Scheimpflug technique (Pentacam) enables the measurement of the corneal refractive power by examining the anterior and posterior corneal curvature. METHOD: The corneal refractive power of 59 eyes was examined before, 3 months and 6 months after myopic LASIK. The refractive power was measured at the corneal apex and at a distance of 2 and 4 mm. Statistical analysis was performed using the Wilcoxon signed rank test; a p value of 0.05 or less was considered statistically significant. RESULTS: At the corneal apex and at a distance of 2 mm the findings with the Keratograph showed a higher refractive power of up to 1.05 D. The differences were statistically significant at all times. At a distance of 4 mm from the corneal apex postoperatively there was no statistically significant difference. CONCLUSION: The results using the Pentacam system showed a lower corneal refractive power following myopic LASIK at all times. Its measuring principle compared to that of the Keratograph should be preferred when detecting changes of the refractive power of the central cornea after corneal refractive procedures.

[Quality control in rehabilitation of patients with visual impairment: evaluation of use and benefits of optic and electronic devices]. / Qualitätskontrolle bei der Rehabilitation sehbehinderter Patienten: Evaluation der Nutzung von Sehhilfen.

BACKGROUND: Not only medical care and prescription of magnifying devices, but also social and professional rehabilitation are part of a complete interdisciplinary low vision service. This study provides quantitative data about the success of rehabilitation and the quality of the Low Vision Department's work. PATIENTS AND METHODS: A sample of 105 visually disabled patients, who had already been provided with magnifying aids and other rehabilitation measures by the Low Vision Department, answered a questionnaire about quality control during a follow-up visit. The survey was carried out between May and October 2004. Patients were asked to rate the different rehabilitation measures and to comment on how frequently they used the different magnifying devices. Furthermore, they were asked to judge to what degree they coped with different life situations when using or not using the low vision aids. RESULTS: The most frequently used aids were magnifiers (61%), glasses for near vision (34%), closed circuit television (20%), and monocular telescopes (20%). Of the 105 patients, 85 (81%) reported on frequent use of the devices, with just 3 patients (3%) reporting that they hardly ever used the aids. Only 2% of the patients could read newspaper text without the use of magnifying aids, while 51% were able to do this using the aids; 46% of the patients reported that they had profited from the social and professional rehabilitation measures. CONCLUSION: Independently from the causal ophthalmologic diagnosis, patients were found to have benefited greatly from the rehabilitation measures provided by the Low Vision Department, enabling them to take part in more activities and participate more fully in social life, thereby greatly improving their quality of life. Frequent use of the low vision aids by the patient was ensured when offered alongside continued professional support.

Management of spontaneous rupture of the oesophagus (Boerhaave's syndrome): single centre experience of 18 cases.

BACKGROUND: Spontaneous oesophageal rupture (Boerhaave's syndrome) is rare, and carries a high attendant risk of mortality. METHODS: A retrospective eight-year review from a tertiary unit. RESULTS: Eighteen patients were managed, with a mean age of 57 (39 - 88 years). Eight patients presented early and underwent surgery, seven with primary closure and one with exclusion and diversion. There was one death in this group. Ten patients were managed conservatively. In this group, two underwent an oesophagectomy because of failed conservative measures, and four had an endoprosthesis inserted. One patient died in this group on the first admission, but two patients with stents in situ died from massive bleeding relating to an aorto-oesophageal fistula at 39 days and 189 days respectively following presentation. CONCLUSIONS: Surgical intervention remains the gold standard when the diagnosis is made early. For late diagnoses, this series suggests caution in the use of endoprostheses.
