Estimation of crowd size for large gatherings is an indispensable metric for event planners, local authorities, and emergency management. Currently, most crowd counting relies on dated methods such as people counters, entrance sensors, and ticket sales. Over the past decade, there has been rapid development in crowd counting techniques and related technology. Despite progress, theoretical advances in crowd counting technology have outpaced practical applications. The emergence of the vast array of crowd counting techniques has added to the challenge of determining those advances that can be most readily implemented. This article aims to provide an overview of promising crowd counting strategies and recent developments applied within the disaster medicine context along with the best use cases and limitations.

To compare the clinical outcomes of a low dose dexamethasone strategy vs. a high-dose dexamethasone strategy in hypoxemic COVID-19 patients. A retrospective observational study comparing low-dose (8 mg) and high-dose dexamethasone (24 mg) of COVID-19 patients admitted from September 1, 2020 to October 31, 2020 in a hospital in Honduras. We included 81 patients with confirmed COVID-19 who required oxygen therapy. The mean age was similar between groups (57.49 vs. 56.95 years). There were more male patients in the group of 24 mg ( p = 0.01). Besides, patients on the 24 mg dose had more prevalence of hypertension ( p = 0.052). More patients in the 24 mg group had a higher rate of invasive mechanical ventilation (15.00% vs. 2.56%, p = 0.058). When evaluating the association between the high dose group and outcomes, we find no significant association with mortality, nosocomial infections, high flow mask, invasive mechanical ventilation, or the need for vasopressors. We find no significant differences in the Kaplan-Meier analysis regarding the survival (log-rank p -value = 0.315). We did not find significant differences between the use of 24 mg and 8 mg of dexamethasone in hypoxemic COVID-19 patients.

Background: Spinal epidural abscess (SEA) is an uncommon but serious differential diagnosis of acute spinal pain with high paralysis and mortality rate. This study aims to provide local data on its bioclinical characteristics and evaluate potential strategies to enhance its diagnostic rate in accident and emergency department (AED).

Methods: A retrospective case study from 2013 to 2019 was conducted in United Christian Hospital. SEA cases were classified as study group, spinal pain due to non-SEA cases were classified as control group. Data collected from study group included symptoms, radiological diagnosis, microbiological culture, treatment, and outcome. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) of both groups were compared to analyze their diagnostic power.

Results: In the study group (n = 42), 93% of patients had spinal pain, 55% had fever, 60% had neurological deficits, and only 26% had the classic triad on presentation. Seventy-four percent of patients presented with spinal cord or cauda equina compression in their first magnetic resonance imaging. Mortality rate was 23.8%, and paralysis rate was 7.1%. Diagnostic accuracy in AED was 12%. Admission to orthopedic ward (n = 23) resulted in a significantly lower mean time-to-imaging (4.39 days vs. 14.58 days) and mean time-to-treatment (6.56 days vs. 16.9 days) as compared to other specialties. The area under curves of CRP and ESR were 0.893 and 0.874 respectively, the optimal threshold levels were 45.9 mg/L (sensitivity 82.9%, specificity 79%) and 59.5 mm/hr (sensitivity 87.2%, specificity 80.4%), respectively.

Conclusion: Diagnosis of SEA in emergency department based on clinical symptomatology is not reliable due to low incidence of the classic triad, despite a more advanced disease on presentation. We proposed incorporating CRP and ESR tests into evaluation of patients with spinal pain since both tests demonstrated excellent discriminative power in diagnosing SEA.

This case involves a 41-year-old male experiencing agitation and confusion due to betel nut intoxication. The diagnosis was made by identifying the toxidrome through physical examination. Removing the residual betel nut with a finger and brushing it with water resulted in a significant improvement in consciousness and orientation within one hour. In addition to recognizing the toxidrome, prompt and effective treatment for the intoxicated patient is essential. Given the prevalence of betel nut chewing in Taiwan, emergency physicians should be particularly vigilant of arecoline toxicity.

Dentures dislodged into throat on bilevel positive airway pressure (BiPAP) ventilation can be overlooked and potentially compromise airway patency. An 81-year-old man with a history of chronic obstructive pulmonary disease (COPD) presented with increased shortness of breath and productive cough for 1 week. Inhaled bronchodilators, parenteral steroids, and BiPAP ventilation were administered for acute exacerbation of COPD complicated with acute hypercapnic respiratory failure. Fifty minutes after receiving BiPAP ventilation, his respiratory condition improved; however, he started to complain of neck pain. The patient remained intolerant to the device 3 hours later, despite receiving assurance that the discomfort might be caused by air pressure through mask ventilation. His throat did not exhibit any abnormality during visual examination. Neck radiographs were subsequently obtained and demonstrated a denture impacted in the hypopharynx. His neck pain resolved after the removal of the dislodged maxillary denture. Denture dislodgement can occur in mask ventilation and compromise airway patency if stuck in the hypopharynx or respiratory tract. Such adverse events may be overlooked on the coexistence of respiratory and pulmonary diseases. A precisely pharyngolaryngeal inspection and complete imaging studies must be performed to facilitate early identification and further retrieval intervention.

Background: High-quality cardiopulmonary resuscitation (HQ-CPR) focuses on improving heart and brain blood perfusion. The evaluation of HQ-CPR included depth, frequency, rate of chest compressions, and the occurrence of chest recoil between two chest compressions. Staff performing CPR may not be performing HQ-CPR since it is influenced by individual stamina, physical strength, and lack of target marker. We aimed to study the impact of 100 times per minute rate vs. 120 times per minute CPR rate on the depth and percentage of depth-on-target done by trained staff on a manikin.

Methods: This was a cross-over randomized control study. The subjects were anesthesiology and intensive care residents in a tertiary teaching hospital in Indonesia, all certified to perform advanced life support. The subject was asked to perform both CPR of 100 and 120 times per minute after a period of one-day rest. The standardized adult manikin was used, and the depth of CPR was measured using a pad-sensor attached to the manikin, and the results were transferred to recording software. Analysis was done using the chi-square analysis, and p < 0.05 was considered statistically significant.

Results: A total of 35 subjects were included. The results showed that the average compression depth at 100 times/minute was more statistically superficial than the 120 times/minute treatment (5.210 ± 0.319 vs. 5.430 ± 0.283, p = 0.007). In contrast, the compression depth-on-target percentage was significantly higher at a speed of 100 times per minute (37.130 ± 10.233 vs. 18.730 ± 7.224, p = 0.0001).

Conclusion: One hundred times per minute CPR resulted in a statistically significant lower compression depth, although not clinically significant, with a statistically significant higher percentage of compression depth-on-target than 120 times per minute CPR.
