Background: Crohn's Disease (CD) is typically characterized by abdominal symptoms, however, besides gastrointestinal symptoms, CD patients may suffer from extraintestinal manifestations which are far less common and medical treatment can be challenging., Case Presentation: We report about a 34-year-old Crohn's Disease (CD) patient in clinical remission under adalimumab therapy who presented in the clinic for Cranio-Maxillo Surgery due to severe pain in the mandibular area. Ulcerative lesions of the buccal-side mucosa of the right mandible were detected. To rule out malignancy, a biopsy was obtained and revealed ulcerative stomatitis with noncaseating granulomas consistent with oral CD. Shortening the adalimumab administration interval to weekly injections resulted in a complete healing of the oral CD lesions without residual inflammation., Conclusion: The case presented here demonstrates that gastroenterologists should evaluate and consider oral CD lesions as a possible marker of disease activity in patients despite having quiescent intestinal CD.

Introduction: This case of giant cell arteritis is noteworthy because it evaded standard diagnostic criteria and only emerged as fever of unknown origin. In this regard, we present 18F-fluorodeoxyglucose positron emission tomography as a valid diagnostic method., Case Presentation: This case report describes a 58-year-old Caucasian woman who is a cigarette smoker with a 10-week history of fever of unknown origin, night sweats and weight loss of 12 kg. Initially, clinical presentation was suspicious of malignant disease. Laboratory findings detected significantly elevated inflammatory blood parameters including C-reactive protein and elevated erythrocyte sedimentation rate (110 mm/hour). Extensive diagnostic workup including microbiological and rheumatological assessment, ultrasonography, endoscopy and computed tomography of abdomen and thorax did not indicate any septic or malignant focus. Eventually, 18F-fluorodeoxyglucose positron emission tomography was able to reveal arteritis of her aortic arch and supraaortic branches. Subsequently, she commenced steroid and methotrexate therapy that led to sustained remission., Conclusions: This case of giant cell arteritis may promote discussion regarding a more specific classification for this disease entity. Furthermore, it confirms that 18F-fluorodeoxyglucose positron emission tomography might serve as a valuable tool for diagnosis of giant cell arteritis, because it could facilitate an accurate and non-invasive detection of lesions of large vessels.

Background: As a non-invasive and readily available diagnostic tool, ultrasound is one of the most important imaging techniques in medicine. Ultrasound is usually trained during residency preferable according to German Society of Ultrasound in Medicine (DEGUM) standards. Our curriculum calls for undergraduate training in ultrasound of medical students in their 4th year of undergraduate education. An explorative pilot study evaluated the acceptance of this teaching method, and compared it to other practical activities in medical education at Muenster University., Methods: 240 medical students in their 4th year of undergraduate medical education participated in the training and completed a pre- and post-questionnaire for self-assessment of technical knowledge, self-assurance of the procedure, and motivation in performing ultrasound using a Likert scale. Moreover, students were asked about their interest in pursuing a career in internal medicine. To compare this training to other educational activities a standardized online evaluation tool was used. A direct observation of procedural skills assessment (DOPS) for the first time applied on ultrasound aimed to independently assess the success of our teaching method., Results: There was a significant increase in technical knowledge and self-assurance (p < 0.001) of the students' self-assessments. The clinical relevance and self-motivation of the teaching were evaluated positively. The students' DOPS results demonstrated proficiency in the understanding of anatomic structures shown in ultrasonographic images, including terminology, machine settings, and transducer frequencies., Conclusions: Training ultrasound according to certified DEGUM standards was successful and should be offered in undergraduate medical education. The evaluation of the course affirmed the necessity, quality and clinical relevance of the course with a top ranking score of hands-on training courses within the educational activities of the Medical Faculty of Muenster.
