Nonketotic Hyperglycemic Hemichorea in an Elderly Male: A Case Report.

BACKGROUND: Nonketotic hyperglycemic hemichorea is a rare complication of diabetes mellitus seen in the emergency department. It is most commonly reported in elderly women, predominantly of Asian race, with poorly controlled diabetes mellitus. Patients present with a triad of nonketotic hyperglycemia, hemichorea, and contralateral basal ganglia abnormality on imaging. Its exact pathophysiology is still not known. However, it has a very good prognosis with early diagnosis and treatment. CASE REPORT: We report a case of hemichorea involving the right upper and lower limbs due to nonketotic hyperglycemia. The patient's symptoms resolved after normalization of blood glucose. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Nonketotic hyperglycemic hemichorea should be included in the differential of a patient presenting with chorea and high blood glucose levels. It has an excellent prognosis with both symptoms and imaging abnormalities typically resolving completely with restoration of normoglycemia.

Pneumomediastinum in COVID-19 disease: Clinical review with emphasis on emergency management.

Pneumomediastinum can be primary (spontaneous) or secondary to iatrogenic, traumatic, and non-traumatic causes. The incidence of spontaneous and secondary pneumomediastinum is higher in patients with coronavirus disease 2019 (COVID-19) compared to the general population. So, pneumomediastinum should be considered in the differential diagnosis of any patient with COVID-19 presenting with chest pain and breathlessness. A high level of suspicion is required to diagnose this condition promptly. Unlike in other disease conditions, pneumomediastinum in COVID-19 has a complicated course with higher mortality in intubated patients. No guidelines exist for managing pneumomediastinum patients with COVID-19. Therefore, emergency physicians should be aware of the various treatment modalities besides conservative management for pneumomediastinum and life-saving interventions for tension pneumomediastinum.

Unusual Presentation of a Common Diagnosis in a Patient With Chronic Kidney Disease.

This case report describes a patient in their 40s with chronic kidney disease who presented to the emergency department with acute-onset breathlessness for 2 hours.

Effectiveness of "Resuscitation Cover All" in Minimizing COVID-19 Transmission to Health-Care Workers during Cardiopulmonary Resuscitation.

Introduction: Coronavirus disease 2019 (COVID-19) is a highly contagious disease transmitted by contact, droplets, and aerosols. Front line health-care workers (HCWs), particularly emergency physicians and acute care providers, are vulnerable to being exposed while treating their sick patients. Despite appropriate personal protective equipment use, HCW gets infected, suggesting the need for multiple layers of protection such as barrier devices. Methods: We aimed to determine the effectiveness of our novel "Resuscitation Cover All"(RCA) in reducing the exposure of HCW to simulated respiratory particles and its feasibility during cardio pulmonary resuscitation (CPR). This was a pilot simulation-based study. Five CPR simulation sessions were performed in Standard and RCA protocols, individually. Exposures through contact, droplets, and aerosols were simulated using a standardized volume of liquid detergent. Under Wood's lamp illumination, exposures of participants were compared between the protocols. Rate and depth of chest compressions, time taken to intubate, interruptions in CPR, and first-pass success were analyzed. Results: Overall mean exposure in standard protocol was 4950.4 ± 1461.6 (95%confidence interval [CI]:3135.7-6765.2) sq.pixels and RCA protocol was 2203.6 ± 1499.0 (95%CI: 342.4-4064.9) sq.pixels (P = 0.019). In standard, chest compressor had the highest exposure of 3066.6 ± 1419.2 (95%CI: 2051.3-4081.9) sq.pixels followed by defibrillator assistant 1166.4 ± 767.4 (95%CI: 617.4-1715.4) sq.pixels. Chest compressor of RCA had reduced exposure compared to that of standard (P < 0.001). Hands were the most frequently exposed body part. Airway manager of RCA had no exposure over head and neck in any session. No significant difference in CPR performance metrics was observed. Conclusion: This pilot simulation-based study shows that the novel RCA device could minimize the exposure of HCW to simulated respiratory particles during CPR. Also, it might not alter the high-quality CPR performance metrics. We need more real-life evidence.

Designing a universal tool for developing content of debriefing: The how and what questions.

Objectives: Clear and specific content for debriefing promotes learning and reflection for the learner. Currently, there is no universal tool for developing the content for debriefing. Methods: We developed a tool for debriefing that can be applied for developing content for debriefing, which can be used for instructor-led and within-team debriefing. These tools include two sets of eight questions, namely, the how and the what questions. Results: We used these tools in our monthly simulation activities and got a favorable response from the residents who used them. Conclusions: The how question deals with human factors, and the what questions deal with educational factors.
