RESUMO

INTRODUCTION: The general shortage of medical doctors in Germany can also be felt in the area of trauma and orthopaedics. Medical elective placements, in Germany known as "Famulatur", are sensitive interfaces between the theoretical university studies and the practical medical workplace. In this research project, the aim was to study how medical students perceive these types of placements and if it alters their decision making when planning their further career. METHODS: During the summer term of 2012, 9079 medical students answered an online questionnaire. Of these, the subgroup was evaluated that had had a placement of at least 4 weeks in the field of trauma and orthopaedics. Overall, 37 test items about this placement and further career steps were included in this study. Groups were evaluated separately by the item "I am considering a career in trauma and orthopaedics" (PJ-Ja) versus "I am not considering a career in trauma and orthopaedics" (PJ-Nein). RESULTS: Overall 397 students were included in this study; 55 % were female. 267 (67.3 %) stated: "I am considering a career in trauma and orthopaedics"; 130 (32.7 %) were not. There was no significant difference in age or sex between these groups (sex: χ²= 2.50, p = 0.114; age: F[1.93]< 1, p = 0.764). Specific and statistically significant differences between those groups were found in the items team integration, ward climate, qualification of teaching, training for specific knowledge in the field, practical aspects of the tasks performed, general planning and structure of the elective achievement of the teaching goals. DISCUSSION: Knowledge of satisfaction during medical elective placements is essential if one aims to inspire students for a specific medical profession. Instructors who can identify weaknesses and deficits in their training regime can therefore in the future increase the number of medical doctors who choose their speciality. The foundation of personal development has to be laid very early in the career of medical students.

RESUMO

INTRODUCTION: The changes in medical licensing regulations introduced in Germany in 2012 require the development of specific catalogues, termed logbooks, that define the practical skills medical students should acquire in different specialties. In conjunction with another change in medical education, which allows medical students to freely select any German university hospital or academic teaching hospital for their one-year internship, these catalogues are a prerequisite for ensuring comparable training standards throughout Germany. The German licensing regulations provide no details regarding the contents or form of the logbooks but only mention a "training programme" in very general terms. A logbook is commonly understood to define clear learning objectives to be accomplished during a specified interval (4 months). The conference of German medical faculties proposed a basic logbook for compulsory training modules (surgery and internal medicine) that is intended to serve as a model (formally and contentwise) for those who develop similar catalogues for elective training modules. Here we present our logbook for an elective training module in orthopaedic surgery and traumatology. MATERIAL AND METHOD: The logbook presented here is based on the catalogue of learning outcomes in orthopaedic surgery and traumatology developed by an expert board of the medical teaching study group of the German Society of Orthopaedic Surgery and Traumatology (DGOU) in 2011. The objectives defined for the one-year internship are of necessity divided into orthopaedic surgery and traumatology skills that must be acquired by all medical students and those that are optional (compulsory and elective modules). Using a set of predefined criteria, the authors developed the catalogue of learning outcomes (logbook) presented here. The catalogue outlines the competencies to be acquired in an elective orthopaedic surgery and traumatology module, leaving it to each medical faculty to work out the details. Where applicable, comprehensive skills across a number of (compulsory and elective modules) learning objectives are arranged in such a way that they can be taught at different levels of complexity. RESULTS: The logbook covers 15 skill domains from different specific components of orthopaedic surgery and traumatology. Where these skills overlap with those also required in compulsory modules (e.g., surgery), the required level of complexity may be lower for students in the elective module. The text is supplemented by figures with synopses of the major issues and summaries for easy reference. CONCLUSION: With the recent changes in German licensing regulations for physicians, it has become necessary to set up a logbook of uniform learning outcomes to assist medical students and their teachers alike. The authors have developed such a logbook of elective training modules in orthopaedic surgery and traumatology to be taught during the one-year undergraduate internship of German medical students.

RESUMO

INTRODUCTION: Practical training on clinical cases and work with patients is one of the most important steps within the educational programme of undergraduates. Until now a general programme with specific learning targets for undergraduate training in orthopedic and trauma surgery is lacking. MATERIAL AND METHOD: In this article we present an educational skills programme developed by a national committee composed of specialists in the field of orthopaedic and trauma surgery. This programme is based on existing guidelines of German medical universities. RESULTS: The facultative and obligatory guidelines developed by the national committee are presented. CONCLUSION: The presented learning programme contains chapters regarding the increasing requirements within the field of orthopaedic and trauma surgery and provides reproducible contents with the possibility for learning control.

RESUMO

PURPOSE: The purpose of this study was to compare the prenatal detection of four congenital heart defects (CHDs) and the image quality of five corresponding ultrasound planes among obese, overweight and normal-weight women. MATERIALS AND METHODS: This was a retrospective cohort study of 54,846 pregnancies undergoing fetal echocardiography between 18 and 37 weeks of gestation in the years from 2000 to 2007. The women were categorized according to pre-pregnancy body mass index (BMI) as normal-weight (BMI < 25), overweight (BMI 25 - 29.9) and obese (BMI ≥ 30). Image quality and prenatal detection of atrioventricular septal defect (AVSD), double outlet right ventricle (DORV), tetralogy of fallot (TOF) and dextro transposition of the great arteries (D-TGA) were evaluated in the BMI strata. RESULTS: 108 cases with one of the considered CHDs were identified. The prevalence was significantly higher (relative risk = 2.04) in overweight or obese women (57/19,404 vs. 51/35,442, p < 0.0002) than in normal-weight women. In total 86.1% of CHDs were correctly identified prenatally (93/108, CI: 79.6%-92.6%), 84.3% (43/51) in the normal weight group, 88.6% (39/44) in the overweight group and 84.6% (11/13) in the obese group. The rate of insufficient ultrasound images increased from 6.4% in normal-weight patients to 17.4% in obese women within the 108 CHD cases. CONCLUSION: The prenatal detection of fetal AVSD, DORV, TOF and D-TGA was also satisfactory in overweight and obese patients, but image quality substantially decreases with an increasing maternal BMI. If there is a BMI-associated difference in the detection rate, it probably will not exceed 20%.

RESUMO

OBJECTIVE: To examine the prevalence of reversed a-wave in the ductus venosus, tricuspid regurgitation and absent nasal bone, in a second-trimester population undergoing amniocentesis, after exclusion of major fetal defects and to estimate the performance in screening for trisomy 21 based on maternal age and these markers in a general population. METHODS: This was a retrospective study involving pregnancies undergoing amniocentesis due to increased risk for trisomy 21, mainly because of advanced maternal age. Before the invasive procedure, an ultrasound examination was carried out to exclude major fetal defects and to examine the ductus venosus, tricuspid blood flow and the presence of the fetal nasal bone. Modeling techniques were used based on 20 000 euploid pregnancies and 20 000 pregnancies with trisomy 21 to assess the screening performance in a general population. RESULTS: The study population consisted of 3613 euploid pregnancies and 35 cases with trisomy 21. In the euploid group, reversed flow in the ductus venosus, tricuspid regurgitation and an absent nasal bone was observed in 1.7%, 1.5% and 0.1% of cases, respectively. In the trisomic group, these markers were found in 14.3%, 11.4% and 14.3% of cases, respectively. For a 5% false-positive rate, the detection rate in screening for trisomy 21, based on maternal age and either ductus venosus, tricuspid blood flow or nasal bone would be 33.8%, 32.4% or 31.4%, respectively. Screening by maternal age alone would detect 29.0% of the fetuses with trisomy 21. Receiver-operating characteristics curve analysis showed a slight but significant improvement in screening performance for trisomy 21 based on the inclusion of these markers. CONCLUSION: Second-trimester ultrasound screening for trisomy 21 based on maternal age with additional assessment of the ductus venosus, tricuspid blood flow and the fetal nasal bone in otherwise normal-appearing fetuses is only marginally better than is screening by maternal age alone.

RESUMO

AIM: The fusion of orthopaedic and trauma surgery into a combined specialty requires a new evaluation of postgraduate and undergraduate training. This study presents a structured analysis of the implementation possibilities for undergraduate training. METHOD: After defining 3 implementation alternatives for both clinical training and last year electives, SWOT analyses were performed. RESULTS. The SWOT analysis demonstrates for each of these 6 implementation models the strengths, weaknesses, opportunities and threats. CONCLUSION: In order to strengthen undergraduate training in the "new" specialty all medical faculties should discuss and define their implementation concepts.

RESUMO

BACKGROUND: The survival of infants born with esophageal atresia (EA) is > 90% at present. The purpose of this study was to evaluate early complications and long term outcome in children with EA treated at our institution. METHODS AND PATIENTS: Retrospective analysis of 111 children with EA undergoing repair of EA or tracheoesophageal fistula (TEF). Assessment of early and intermediate complications as well as long term morbidity and mortality. RESULTS: Primary anastomosis was performed in 90 (81%) and secondary anastomosis in 7 patients (6%). Gastric transposition was carried out in 14 children (13%). The postoperative mortality was 14/111 (12.6%) and could be estimated by the Spitz classification. At the age of 10 years, 33 patients (72%) were swallowing without problems, 39 children (85%) were eating at least most of the time with pleasure but 19 children (41%) had a body weight less than the 25 (th) percentile. Staged repair by gastric transposition resulted in the least amount of motility dysfunction. Long-term respiratory morbidity was high. CONCLUSION: The survival of children with EA has improved in the last two decades. For risk assessment the Spitz' classification is valid. Long term gastrointestinal and respiratory morbidity remains high. In children with long-gap EA gastric transposition performed as a staged procedure has satisfactory results and seems superior to techniques preserving the native esophagus.

RESUMO

OBJECTIVE: To evaluate and compare the screening performance for fetal trisomy 21 in the first trimester of pregnancy either with or without inclusion of fetal nasal bone using two separate risk-algorithms of the Fetal Medicine Foundation London (FMF). METHODS: This study included 3174 patients self-referred to our tertiary level prenatal centre for first trimester screening at 11-14 weeks of gestation between December 1, 2002 and November 30, 2004. Fetal risk for trisomy 21 was calculated using either the old FMF-algorithm including maternal age, nuchal translucency (NT), free ss-human chorionic gonadotropin (hCG), pregnancy-associated plasma protein-A (PAPP-A) or the new FMF-algorithm using additionally the presence or absence of fetal nasal bone (NB). All ultrasonographers were certified for measurement of nuchal translucency and nasal bone by the Fetal Medicine Foundation Germany. The detection rate for a fixed risk cut-off (1:300) and a fixed false-positive rate (5 %) was calculated for ultrasound (single NT or NT and NB), serum biochemistry, maternal age and the combination of these components. RESULTS: Pregnancy outcome was obtained in 2973 (93.6 %) cases. Nasal bone was absent in 5 of 18 (27.8 %) cases with fetal trisomy 21 and in 2 of 2961 (0.1 %) normal cases. The estimated risks for trisomy 21 based on maternal age, fetal ultrasound and maternal serum free ss-hCG and PAPP-A was 1 in 300 or greater in (old algorithm without NB/new algorithm including NB) 5.5 % (179 of 2961) and 2.8 % (97 of 2961) normal pregnancies and in 94.4 % (17 of 18) and 77.8 % (14 of 18) of those with trisomy 21. For a fixed false-positive rate of 5 % the respective detection rates of screening for fetal Down's syndrome by maternal age and serum free ss-hCG and PAAP-A, maternal age and fetal ultrasound and by maternal age, fetal ultrasound and maternal serum biochemistry were (old algorithm without NB/new algorithm including NB) 72.2 %/66.7 %, 83.3 %/77.8 % and 88.9 %/83.3 %, respectively. CONCLUSION: Our data show no additional performance of including presence or absence of fetal nasal bone in calculation of risk for fetal Down's syndrome between 11 and 14 weeks of gestation. Individual risk-orientated two-stage screening could be an alternative approach for integration of additional ultrasound markers in first trimester screening.

RESUMO

PURPOSE: To assess which cataract operation technique involves least risk of postoperative endophthalmitis, when performed in a population living in poor hygiene conditions. METHODS: This retrospective clinical study evaluated 2446 cases at the Eye Clinic of the Komotini General Hospital, Greece, between January 1998 and January 2001. RESULTS: Endophthalmitis arose in 12/1055 patients (1.13%) after extracapsular cataract extraction (ECCE) and in 8/1391 after phacoemulsification (0.57%). The mean time to onset of endophthalmitis was 23 and 73 days respectively after phacoemulsification and ECCE. This difference was statistically significant. CONCLUSIONS: Endophthalmitis develops considerably later after ECCE than phacoemulsification. Thus it would appear that hygiene conditions have a stronger effect in patients operated with the ECCE technique. In order to reduce the risk of endophthalmitis after cataract extraction in patients living in substandard conditions, phacoemulsification is proposed as preferable to ECCE.

RESUMO

Standard ozone monitoring techniques utilize large, heavy, and expensive instruments that are not easily adapted for personal or microenvironmental monitoring. For large-scale monitoring projects that examine spatial variations of a pollutant and human exposure assessments, passive sampling devices can provide the methodology to meet monitoring and statistical goals. Recently, we developed a coated filter for ozone collection that we used in a commercially available passive sampling device. Successful preliminary results merited further validation tests, which are presented in this report. The passive ozone sampler used in field and laboratory experiments consists of a badge clip supporting a barrel-shaped body that contains two coated glass fiber filters. The principle component of the coating is nitrite ion, which in the presence of ozone is oxidized to nitrate ion on the filter medium (NO2- + O3 produces NO3- + O2). After sample collection, the filters were extracted with ultrapure water and analyzed for nitrate ion by ion chromatography. The results from laboratory and field validation tests indicated excellent agreement between the passive method and standard ozone monitoring techniques. We determined that relative humidity (ranging from 10% to 80%) and temperature (ranging from 0 degrees C to 40 degrees C) at typical ambient ozone levels (40 to 100 parts per billion) do not influence sampler performance. Face velocity and sampler orientation with respect to wind direction were found to affect the sampler's collection rate of ozone. Using a protective cup, which acts as both a wind screen and a rain cover, we were able to obtain a constant collection rate over a wide range of wind speeds.

RESUMO

The Particle Total Exposure Assessment Methodology (PTEAM) study provided the opportunity to test methodologies for measuring personal and microenvironmental PM10 and PM2.5 concentrations in a full-scale probability-based sample of 178 persons and homes in Riverside, California during the fall of 1990. The purpose of the study was to estimate frequency distributions of exposure to PM10, PM2.5, and selected elements in an urban population. Quality control samples and analyses were used to evaluate method performance. These included collocated sample collection, field and lab blank filters, sampler and balance field audits, and intra- and interlaboratory replicate elemental analyses. A portion of the study was also designed to include side-by-side operation of the personal and microenvironmental samplers with reference method (high-volume and dichotomous) samplers to provide an evaluation of method comparability. Over 95% of the approximately 2,900 scheduled samples were collected and analyzed, with very few losses due to equipment failure. The method limit of detection for the personal and microenvironmental monitor PM10 sampling was 8 micrograms/m3. Mean relative standard deviations (RSDs) of 2% to 8% were obtained for collocated personal and microenvironmental samples. Sampler flow rates were within the +/- 10% accuracy criterion during two field audits. Balances operated in a specially designed mobile laboratory were within specified tolerances for precision (+/- 4 micrograms) and accuracy (+/- 50 micrograms). Elemental analysis accuracy was measured with standard reference materials with biases ranging from 2% to 7%. Measurement precision for most elements ranged from 2.5% to 25% mean RSD. Personal and microenvironmental samplers gave median PM10 concentrations that were approximately 9% higher than the dichotomous sampler and 16% higher than the high-volume sampler across 96 monitoring periods at a fixed outdoor location.
