[Pneumology in the Model Degree Program of the Medical Faculty Ostwestfalen Lippe, Germany]. / Das Fach Pneumologie im Modellstudiengang der Medizinischen Fakultät Ostwestfalen-Lippe (OWL).

The specialist field of "pneumology" is still underrepresented in university clinics in Germany, but this is not the case at the newly founded medical faculty Ostwestfalen-Lippe (OWL) in Bielefeld. This is linked to representing pneumology and internal intensive care medicine in patient care, teaching and research across the board and the opportunity to actively help shape the development of the human medicine faculty in an exciting environment.The early anchoring of the subject "Pneumology" in the model degree program of medical school in OWL (begin winter semester 2021/22) contributes to further visibility and a university medical orientation. In this overview various issues of Pneumology in the Model Degree Program are explored by basic scientists, clinical teachers, members of the medical faculty and a student.In today's Evangelisches Klinikum Bethel (EvKB), pulmonary medicine has a long tradition. The hospital's first lung and infection center was opened in 1927. The EvKB's department for internal medicine, pneumology and intensive care medicine, which has been independent since 2009, is becoming a university clinic for pneumology within the medical faculty OWL. Relevant translational and interdisciplinary research can be intensified.There are 30 "Pneumology" teaching units in the model degree program, which are divided into two study sections using different formats, such as lectures, seminars, hands on courses and skills lab. It is represented in particular in the module complex "Circulation and Respiration". The content of the first phase of teaching was carried out by a module commission, with members representing the subjects involved in the module.Knowledge of the basics from, for example, physiology, pathophysiology, anatomy and pathology are taught to the students in the run-up to the pneumology course. Using the example of physiology, the presentation of the learning content of a basic subject is elaborated in this article.Half of all teaching units on pneumology of the entire course took place in the 2nd semester (in March and April 2022), so that students experienced the clinical relevance of the content at an early stage. There was a particular focus on obstructive airway and restrictive lung diseases. After imparting the basic knowledge of the physical examination of the lungs in the Skills Lab, the most important pathological findings in the above-mentioned diseases on inspection, palpation, auscultation and percussion are demonstrated and practised in patients as part of bedside teaching under supervision.Communication training is also longitudinally integrated into the modular teaching, with a total of more than 200 teaching hours and is performed interdisciplinary. In the "Circulation and Breathing" module eight hours are devoted to this with simulated patients, the anamnesis and therapy advice on classic cardiopulmonary diseases. For the students, integrating the teaching of basic theory and its clinical application for each organ systems represents a challenge in the model degree program, the advantages outweigh from today's perspective.

Anatomical versus functional motor points of selected upper body muscles.

INTRODUCTION: In this study we aimed to identify nerve entry points (NEPs) of superficial skeletal muscles obtained by dissection of 20 human cadavers and compared them with motor points (MP) obtained previously by electrical stimulation. METHODS: The biceps brachii (BB), trapezius (TZ), latissimus dorsi (LD), pectoralis major (Pmaj), and pectoralis minor (Pmin) muscles were dissected from human cadavers. NEP data (mean ± standard deviation) from each muscle were calculated. F-tests with Bonferroni corrections were used to compare NEPs and MPs. RESULTS: The number of NEPs was 2 in BB, 1 in Pmin, 4 in TZ, and 3 in LD, whereas the total number in Pmaj varied from 3 to 5. NEPs and MPs were statistically equal only in Pmin and in the descending part of TZ. DISCUSSION: The findings show crucial differences between NEPs and MPs, possibly impacting the effectiveness of several medical treatment strategies. Muscle Nerve 57: 460-465, 2018.

Integrating personalized medical test contents with XML and XSL-FO.

BACKGROUND: In 2004 the adoption of a modular curriculum at the medical faculty in Muenster led to the introduction of centralized examinations based on multiple-choice questions (MCQs). We report on how organizational challenges of realizing faculty-wide personalized tests were addressed by implementation of a specialized software module to automatically generate test sheets from individual test registrations and MCQ contents. METHODS: Key steps of the presented method for preparing personalized test sheets are (1) the compilation of relevant item contents and graphical media from a relational database with database queries, (2) the creation of Extensible Markup Language (XML) intermediates, and (3) the transformation into paginated documents. RESULTS: The software module by use of an open source print formatter consistently produced high-quality test sheets, while the blending of vectorized textual contents and pixel graphics resulted in efficient output file sizes. Concomitantly the module permitted an individual randomization of item sequences to prevent illicit collusion. CONCLUSIONS: The automatic generation of personalized MCQ test sheets is feasible using freely available open source software libraries, and can be efficiently deployed on a faculty-wide scale.

Primary tumour size is a prognostic parameter in patients suffering from differentiated thyroid carcinoma with extrathyroidal growth: results of the MSDS trial.

OBJECTIVE: The Multicentre Study Differentiated Thyroid Cancer (MSDS) collective represents a well-defined group of patients with thyroid carcinomas with extrathyroidal extension. The aim of the present study was to evaluate the relationship of the primary tumour size with clinicopathological features as well as the outcome of patients with minimum and extensive extrathyroidal growth (pT3b- and pT4a-tumours; UICC 2002/2003, 6th ed). METHODS: The tumour diameter was available in 324 out of 351 MSDS patients (244 females, 80 males). Mean age of patients was 47.7±12.0 years (range, 20.1-69.8 years), and the median follow-up was 6.2 years. The relationship between primary tumour size and the following clinicopathological data was investigated: age, gender, histological tumour type (papillary thyroid carcinomas (PTC) versus follicular thyroid carcinomas (FTC)) and UICC/AJCC TNM classification. In addition, the correlation between primary tumour size and event-free and overall survival was assessed. RESULTS: The FTC of our series were significantly larger than PTC (3.46 vs 1.84 cm; P<0.001). Patients suffering from pT3b-tumours presented with significantly smaller tumour size than those with extensive extrathyroidal growth (pT4a-tumours) (1.9 vs 3.0 cm; P<0.01). All patients with distant metastases suffered from tumours >2 cm. Furthermore, event-free and overall survival were significantly correlated with increasing tumour size (P<0.05). Using multivariate analysis, a pT4a-category and a tumour diameter >2 cm remained independent predictors of survival. CONCLUSIONS: In patients suffering from differentiated thyroid carcinoma with extrathyroidal growth (pT3b and pT4a), the tumour size is an independent predictor of event-free and overall survival.

LOINC codes for hospital information systems documents: a case study.

Hospital Information Systems (HIS) handle a large number of different types of documents. Exchange and analysis of data from different HIS is facilitated by the use of standardized codes to identify document types. HL7's Clinical Document Architecture (CDA) uses LOINC (logical observation identifiers names and Codes) codes for clinical documents. The authors assessed the coverage of LOINC codes for document types in a German HIS. The authors analyzed document types that occurred more than 10 times in approximately 1.3 million documents in a commercial HIS at a major German University Hospital. Document types were mapped manually to LOINC using the Regenstrief LOINC Mapping Assistant (RELMA). Each document type was coded by two physicians. In case of discrepancies a third expert was consulted to reach consensus. For 76 of 86 document categories a LOINC code was identified, but for 38 of these categories, the LOINC code was not specific as deemed necessary. More than 93% of our local HIS documents had local document types that could be assigned a LOINC code.

Computed Quality Assessment of MPEG4-compressed DICOM Video Data.

Digital Imaging and Communication in Medicine (DICOM) has become one of the most popular standards in medicine. This standard specifies the exact procedures in which digital images are exchanged between devices, either using a network or storage medium. Sources for images vary; therefore there exist definitions for the exchange for CR, CT, NMR, angiography, sonography and so on. With its spreading, with the increasing amount of sources included, data volume is increasing, too. This affects storage and traffic. While for long-time storage data compression is generally not accepted at the moment, there are many situations where data compression is possible: Telemedicine for educational purposes (e.g. students at home using low speed internet connections), presentations with standard-resolution video projectors, or even the supply on wards combined receiving written findings. DICOM comprises compression: for still image there is JPEG, for video MPEG-2 is adopted. Within the last years MPEG-2 has been evolved to MPEG-4, which squeezes data even better, but the risk of significant errors increases, too. Within the last years effects of compression have been analyzed for entertainment movies, but these are not comparable to videos of physical examinations (e.g. echocardiography). In medical videos an individual image plays a more important role. Erroneous single images affect total quality even more. Additionally, the effect of compression can not be generalized from one test series to all videos. The result depends strongly on the source. Some investigations have been presented, where different MPEG-4 algorithms compressed videos have been compared and rated manually. But they describe only the results in an elected testbed. In this paper some methods derived from video rating are presented and discussed for an automatically created quality control for the compression of medical videos, primary stored in DICOM containers.

The Clinical Document Architecture (CDA) enables electronic medical records to wireless mobile computing.

The Clinical Document Architecture (CDA) has proved to be a valuable and powerful standard for a structured exchange of clinical documents between heterogeneous software systems like a Hospital Information System and a Physician Office System. In this paper we want to show how the CDA can additionally be used in order to enhance the Hospital Information System's functionality: each patient related document contained in or generated from the HIS can be converted to a CDA/XML document. With the XML/XSLT-based transformation methods, those documents can be device-specifically transformed. We use this method to display HIS-content on mobile devices like Personal Digital Assistants (PDAs) by extracting the respective data fields from the HIS database, converting them to a CDA/XML document, which is transformed and sent to the mobile devices using a wireless intranet connection. Preliminary results and users' comments are promising, but further evaluation will be necessary. Our approach shows a generic model how clinical data can be dis-played on different devices independently from the underlying HIS using CDA.
