[Prehospital care of anaphylactic reactions by the air rescue and ground-based emergency services Dresden : An analysis of treatment and outcome]. / Präklinische Versorgung von anaphylaktischen Reaktionen durch die Dresdner Luft- und Bodenrettung : Analyse von Therapie und Outcome.

BACKGROUND: Anaphylaxis can lead to a life-threatening situation. Therefore, rapid diagnosis and emergency treatment is indicated. Immediate treatment with intramuscular adrenaline (or intravascularly with sufficient medical expertise) in anaphylaxis with cardiovascular and/or respiratory symptoms is recommended by various guidelines. Previous studies have shown that anaphylaxis is often not treated according to guidelines and that adrenaline in particular is rarely administered. OBJECTIVE: The aim of the study was to investigate the data on emergency treatment and outcomes of patients with anaphylaxis by the air rescue and ground-based emergency services Dresden. Moreover, the results of the air- and ground-based services were compared. The focus was on administration of adrenaline and outcomes. MATERIALS AND METHODS: Data from the ground-based emergency service Dresden (from 2012 to 2016) and the air rescue service Dresden (from 2008 to 2015) related to anaphylactic reactions were analyzed retrospectively. The severity of the anaphylaxis, the emergency medication administered, further monitoring, and outcomes were analyzed. RESULTS: Data from 152 adults/29 children were analyzed for air rescue and 1131 adults/223 children for the ground-based emergency service. Adults with grade II-IV anaphylaxis received adrenaline in 19% (air rescue) and 7% (ground rescue) of cases. Children with grade II-IV anaphylaxis received adrenaline in 7% (air rescue) and 8% (ground rescue) of cases. Immediate drug therapy led to an improvement in general condition in 96-98% (air rescue) and 72-77% (ground-based emergency service) of cases. A significant correlation was found between the administration of adrenaline and the improvement in outcome in the ground-based emergency cohort. CONCLUSION: Guideline-compliant first-line therapy with adrenaline was not performed in the majority of the cases analyzed in this study. The significant effect of adrenaline on outcome demonstrated in this study emphases the need to improve the emergency treatment of anaphylactic reactions.

Low-cost simulation model for ultrasound-guided punch biopsy and puncture: Construction manual and photo examples.

PURPOSE: Ultrasound-guided puncture and punch biopsy pose a particular challenge in ultrasound examination training. These techniques should be learned and performed several times using a simulation model that is as realistic as possible before being applied to patients. While the use of agar-agar-based models is extensively documented in the literature, there is a discernible gap in publications specifically addressing their use in punch biopsy and puncture. The aim was to develop a cost-effective model for the simulation of ultrasound-guided interventions. MATERIALS AND METHODS: The developed simulation model is based on the vegetable gelatine agar-agar. The agar-agar powder is boiled in water and colored. Various objects are added to the mass. Blueberries, olives, tomatoes, and cornichons imitate solid structures. Liquid-filled balloons are used to simulate cystic structures. Adding stones can make the exercises more difficult due to hyperechoic reflexes with distal shadowing. RESULTS: With the model, ultrasound-guided puncture and punch biopsies could be successfully simulated, and ultrasound images can be generated for this purpose. The cost of a single model is about 2 euros. Production takes less than 2 hours, including cooling. The pure processing time is 30 minutes. The durability of the models is limited by mold, which occurs after 5 days when stored at room temperature and after 5 weeks in the refrigerator. CONCLUSION: It was shown that it is possible to produce an inexpensive agar-agar-based ultrasound model in a short time and with easily available ingredients to learn ultrasound-guided puncture and punch biopsies.

[Interprofessional evaluation of "soft skills" of students in the practical year]. / Interprofessionelle Evaluation der "Soft Skills" von Studierenden des Praktischen Jahres.

OBJECTIVE: The present study deals with the implementation of a questionnaire with 360° evaluation to assess the performance of students in the practical year (PJ). A special focus is put on the "soft skills" (self-competence, methodological competence, social competence), whose evaluation in medical studies has not yet taken place comprehensively. MATERIAL & METHODS: The study was conducted prospectively with 21 PJ students of the Medical Faculty of the TU Dresden. The assessment was performed by means of a self-designed questionnaire, which was divided into 4 sub-competencies (self-competence, methodological competence, social competence, clinical skills and abilities), which could be assessed by means of a 6-point Likert scale. Four professions were involved in the assessment: Medical Service, Nursing Service, Functional Service, and Administration. RESULTS: On average, the strongest deficits in terms of self-confidence, willingness to perform, and ability to deal with conflict were revealed by students in the PJ. Students showed a very good performance in performing a medical history and basic skills of clinical examination. CONCLUSION: The implementation of 360° feedback is possible and useful for students in the internship year across disciplines and professions. Such personal and interprofessional feedback has not been widely available. The questionnaire represents the first comprehensive measurement tool of soft skills for medical students and provides a good basis for comprehensive feedback.

[Chronic mesotympanic Otitis media - Part 2: Surgical Therapy]. / Chronische mesotympanale Otitis media ­ Teil 2: operative Therapie.

Chronic mesotympanal otitis media (CMOM) is a well-developed clinical presentation that is established in diagnostics and therapy. On closer inspection, however, this principle cannot be confirmed in all its facets. Already the physiology and pathophysiology of the middle ear mucosa leave questions unanswered, starting with the distribution of the ciliated epithelium in the middle ear and mastoid to the function of gas exchange.In addition, there are new diagnostic and therapeutic approaches. In the future, optical coherence tomography could help to determine the status of the middle ear mucosa. In addition, there are new findings on the effectiveness of local and systemic antibiotics as well as antiseptics in chronic otorrhea. Other new developments include minimally invasive surgical procedures using endoscopic techniques. All this gives reason to provide an update on the topic of chronic mesotympanal otitis media, which should contribute in preparation for the specialist examination or refreshing.Basics of physiology and pathophysiology as well as new diagnostic approaches and medical treatment were covered in Part 1 of this paper. In Part 2, in addition to established methods, new developments in surgical therapy with minimally invasive surgical procedures are described in more detail.

Digital teaching and assessment of psychomotor skills of the clinical head and neck examination during COVID-19 pandemic.

PURPOSE: During COVID-19, a fully digital course was established for teaching and assessing the psychomotor skills of clinical head and neck examination. Influence of different digital teaching formats was investigated. METHODS: The students (n = 286) received disposable instruments, a manual, and instructional videos for the examination. 221 students additionally received 45 min of interactive teleteaching. After 5 days of practice, all students were required to submit a video of their examination and report their spent practice time. The assessment was carried out using a checklist which was already established in presence teaching. RESULTS: The average score achieved by digital teaching was 86%. Previously published data show that presence teaching achieved 94%. With a teleteaching unit the total score was significantly better than without (87% vs 83%). Teleteaching leads to a significant positive correlation between practice time and total score. Without teleteaching there is a negative correlation. After the same practice time, presence teaching leads to better total scores than digital teaching. CONCLUSION: Digital teaching and assessing of a complex psychomotor skill is possible. Interactive teaching methods increase learning success. Nevertheless, presence teaching seems to be better at teaching these skills. The results can provide a basis for developing hybrid teaching models.
