Background: Coronavirus disease 2019 (COVID-19) pandemic and its associated precautionary measures have substantial impacts not only on the medical, economic, and social context but also on psychological health. This study aimed to assess the obsession toward COVID-19 preventive measures among undergraduate medical students during the early phase of the pandemic in Jordan.Methods: Online questionnaires were distributed between March 16, 2020 and March 19, 2020. Socio-demographic characteristics were collected, and self-reported obsession toward COVID-19 preventive measures was assessed using a single question.COVID-19 knowledge, risk perception, and precautionary measures were evaluated using scales. Using the chi-square test, Student t-test, and one-way ANOVA, we assessed the differences in the obsession of students with socio-demographic characteristics and scores of the scales.Results: A total of 1,404 participants (60% were female participants) completed the survey with a participation rate of 15.6%. Obsession with preventive measures was reported by 6.8%. Obsession was significantly more common among women (9.2%) than men (3.3%) and students who attended COVID-19 lectures (9.5%) than those who did not attend such lectures (5.8%) (p < 0.001 and p = 0.015, respectively). Obsessed participants reported significantly higher levels of COVID-19 knowledge (p = 0.012) and precautionary measures (p < 0.001). COVID-19 risk perception had a mild effect size difference but with no statistical significance (p = 0.075). There were no significant differences in the academic levels of participants (p = 0.791) and universities (p = 0.807) between students who were obsessed and those who were not.Conclusions: Obsession is one of the significant but unspoken psychological effects of COVID-19 precautionary measures among undergraduate medical students. Medical schools should be equipped with means to handle pandemic psychological effects.

Objective:To assess the cardiovascular responses induced by different nasal adrenaline-lignocaine mixtures infiltrations protocols for patients undergoing septorhinoplasty under general anesthesia. Methods:Our prospective investigation enrolled 212 subjects, aged 26-34 yrs, classified as physical status class I by the American Society of Anesthesiologists (ASAI), of both sexes and scheduled for septorhinoplasty under general endotracheal anesthesia during the period from January 2010 to December 2012, at the King Hussein Hospital, King Hussein Medical Centre, Amman, Jordan. Patients were divided randomly into three groups. Patients in group A (n=70) received nasal sub mucosal infiltration of 10.2 ml of lignocaine 1% (10 mg/ml) with adrenaline 0.0025% (25 mcg/ml). Subjects in group B (n=72) received 10.2 ml of lignocaine 1% with adrenaline 0.00125% (12.5 mcg mg/ml), while subjects in group C (n=70) received 10.2ml of lignocaine 1% with adrenaline 0.000625% (6.25 mcg/ml). Cardiovascular parameters including heart rate, systolic blood pressure and mean arterial pressure were recorded every half minute during the first 5 minutes after nasal infiltration. Inter-group statistical comparisons were performed using ANCOVA and intra-group statistical comparisons were achieved using ANOVA. Results:In comparison with baseline readings, heart rate was mostly increased, systolic blood pressure was mostly decreased and mean arterial pressure was mostly reduced significantly (P<0.05) at 60 seconds time interval post infiltration in all three groups. Conclusions:Local nasal sub mucosal infiltration of different adrenaline concentrations containing lignocaine solutions could increase heart rate and reduce mean arterial pressure during the first five minutes after infiltration.
