RESUMO
The association between myasthenia gravis (MG) and thymomas is well-documented. Thymomas are rare epithelial cell tumors that arise from the thymus gland and occur in the mediastinum. Myasthenia gravis is a neuromuscular disorder that causes skeletal muscle weakness due to the presence of anti-acetylcholinesterase antibodies. Roughly 60% of thymomas are associated with MG, while only 10% of MG patients have thymomas. We present an atypical presentation of myasthenia gravis with an associated unusual metastatic thymoma. This case is of a young, previously healthy 26-year-old male with no previous medical history who presented with non-specific symptoms of fatigue, diarrhea, abdominal pain, back pain, blurry vision, and unintended weight loss. He underwent treatment with intravenous immunoglobulins (IVIG), had two surgical resections of the thymoma, and ultimately received radiotherapy. Based on our experience with this case, diagnosing myasthenia gravis by testing for specific muscle antibodies for patients with ptosis in the setting of non-specific complaints, including fatigue, vomiting, diarrhea, and abdominal or back pain, should be considered. Routine imaging should follow with a chest computed tomography to screen for thymomas if the specific anti-titin and anti-ryanodine receptor (anti-RyR) muscle antibodies are positive and myasthenia gravis is suspected. If a thymoma is confirmed, it is best to confirm; and mass characterizes with chest magnetic resonance imaging. A treatment approach of IVIG followed by surgical resection and possible debulking if the lesion is deemed metastatic could also be considered thereafter, especially in young patients with few comorbidities. Treatment with Pyridostigmine 30 mg twice daily for 25 days post-surgically and radiation for treatment of any remaining unresectable tumor should also be considered.
RESUMO
Background The Accreditation Council for Graduate Medical Education requires residents to demonstrate competence in integrating feedback into their daily practice. With the shift to virtual medical education during the pandemic, the need for new skills in delivering effective feedback through virtual media has emerged. Methodology This study aimed to assess the feasibility of a virtual bootcamp for interns, utilizing virtual simulation workshops to teach effective feedback skills. The curriculum employed a situated learning-guided participation framework. Virtual standardized students participated, and interns engaged in activities such as providing virtual feedback, completing self-assessments, and receiving instruction on feedback principles, including the one-minute preceptor's five micro-skills. Interns repeated the feedback process, with virtual students providing assessments. Data were collected from 105 incoming interns at Arrowhead Regional Medical Center in June 2021 and June 2022, using Zoom® as the online platform. Results Competency assessments revealed a significant post-training increase in proficiency/expert milestones (88% versus 47%, p = 0.007). Interns' self-assessments also significantly improved (18.02 versus 16.74, p = 0.001), particularly for previously trained interns (18.27 versus 16.7). Non-primary care interns outperformed primary care interns in milestone scores. The majority of interns (80%) reported valuable learning experiences during the workshop, with 70% expressing confidence in using the one-minute preceptor technique during residency. The one-minute preceptor step "reinforce what was right" was deemed the easiest, while "obtain commitment" and "explore emotional reaction" presented significant challenges. Conclusions This study demonstrates the potential of virtual workshops to enhance intern competency in delivering effective feedback through formal processes and the one-minute preceptor. These virtual approaches offer innovative alternatives to in-person teaching, enabling evaluation at higher levels of Miller's pyramid of clinical competence.
