Objective: To investigate the clinical features, therapeutic efficacy and symptom time course of post-coronavirus disease 2019 parosmia. Methods: A 22-item online questionnaire was distributed to AbScent research group and Facebook coronavirus disease 2019 anosmia group adult members to assess clinical features, interventions and their subjective efficacy for parosmia. Results: A total of 209 participants (86 per cent females) reported: smell loss on average 3 days after coronavirus symptoms, recovery 4 weeks later, and first parosmia symptoms 12 weeks post infection. Respondents reported 10 per cent body weight loss, and listed onion and garlic as significant parosmia triggers. Regarding quality of life, depression was the most cited item (54 per cent). Smell training was trialled by 74 per cent of participants, followed by nasal corticosteroid spray (49 per cent). Stellate ganglion block, trialled by 16 per cent of respondents, had the highest reported improvement (45 per cent), with 21 per cent reporting a sustained benefit – the highest rate amongst registered treatment options. Conclusion: Post-coronavirus parosmia has a significant impact and remains challenging to treat. Stellate ganglion block appears to be successful relative to other reported treatments. Further research into the pathophysiology, efficacy and mechanism of stellate ganglion block effect is warranted. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Shisha smoking is becoming highly prevalent and is a predominant mode of tobacco use particularly amongst the young generation around the globe. This study aims to investigate whether or not shisha smoking impairs the cognitive functioning in adolescents. SUBJECTS AND METHODS: We recruited 65 (32 control subjects and 33 shisha smokers) apparently healthy male volunteers. The first group consisted of 33 volunteer male shisha smoker subjects with mean age 24.45±2.93 (mean ± SD) years. The second group consists of 32 subjects with mean age 23.31±2.68 (mean ± SD) years who did not smoke shisha. Age, gender, weight, height, ethnicity, educational and socioeconomic status of a matched design was used to appraise the impact of shisha smoking on cognitive functions. The cognitive function's outcome variables were the response time (Attention Switching Task-AST), (Complex Reaction Time-CRT task) and the percentage of correct answers (Pattern Recognition Memory PRM-task). Cognitive functions were assessed by using Cambridge Neuropsychological Automated Battery (CANTAB). RESULTS: Shisha smokers showed significant decline in cognitive performances AST-Latency (p=0.03); AST-Congruent (p=0.05); AST-Incongruent (p=0.05); mean CRT (p=0.001); CRT % (p=0.01); PRM (p=0.024) compared to their matched control. CONCLUSIONS: Cognitive functions including attention, alertness, and memory were significantly impaired in healthy adult shisha smokers compared to non-shisha smokers. [ABSTRACT FROM AUTHOR]

Background: Pediatric emergency admissions fell significantly during the COVID-19 pandemic. This study investigated the changes in severe infectious complications managed by otolaryngology between the pre-pandemic period and the first year of the pandemic to determine if COVID-19 or related public health measures influenced the rate or severity of presentations managed in otolaryngology., Methods: A retrospective chart review was conducted on pediatric patients who presented with severe infectious otolaryngology presentations (acute mastoiditis, deep neck space abscesses, and orbital complications of sinusitis) over the pre-pandemic (March 2018-February 2020) and early pandemic (March 2020-February 2021) periods. Patient characteristics, details of presentation, treatment, and outcomes were extracted from patients' charts. Independent samples t-tests/Mann-Whitney U-tests for continuous variables and Pearson chi-squared tests/Fisher's exact test for categorical variables were conducted to compare the pre vs early pandemic groups., Results: There were 93 pre-pandemic and 28 early pandemic presentations. The monthly case average was significantly lower during the early pandemic period than the 2 years prior [3.58 (2.80) vs 2.00 (2.00), P = .045]. The average monthly frequency of presentations for deep neck space abscess and mastoiditis were significantly higher in the pre-pandemic group when compared to the early pandemic group [1.96 (±0.33) vs 1.33 (±0.48), P = .049; .71 (±0.26) vs 0.17 (±0.41), P = .01, respectively]. The early pandemic group was significantly younger (3.81 vs 6.04 years, P = .005), however there were no differences in gender, length of admission, and days from symptom onset to presentation between the two groups (P > .05). The early pandemic group had significantly elevated inflammatory markers on presentation [CRP, WBC, neutrophils (P = .02, P = .02, P = .04, respectively)] compared to the pre-pandemic group., Conclusion: The COVID-19 pandemic has had an effect on severe infectious complications of ENT pathologies, including decreased average monthly cases during the early pandemic, younger age at presentation, and elevated inflammatory markers., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Elsevier B.V.

Introduction: Healthcare providers are at high risk of becoming infected when taking care of patients who have COVID-19, especially while attending aerosol generating procedures. Protective personal equipment must be used in the correct manner to prevent transmission of the disease. Published protocols on protective personal equipment (PPE) donning and doffing have been issued by disease control agencies., Methods: A questionnaire-based cross-sectional study was designed. An online anonymous questionnaire, which was validated and tested for reliability, focused on PPE related knowledge, donning and doffing practices of healthcare providers across the eastern region of Saudi Arabia., Results: A total of 312 healthcare providers across the eastern region of Saudi Arabia participated in the study, 208 physicians (66.7%) and 104 non-physicians (33.3%). Results indicate poor practice regarding PPE donning (13.8% reported the correct sequence) and PPE doffing (3.5% reported the correct sequence) among participants. In addition, practice and confidence scores regarding other issues with PPE were analyzed. Based on questionnaire responses, being male (T = 2.825; p = 0.008), being a non-physician (T = -2.120; p = 0.014) and being an allied medical professional (F = 5.379; p = 0.003) were significantly associated with higher confidence levels. Also, being a consultant was significantly associated with higher practice scores (F = 4.774; p = 0.008)., Conclusion: The study demonstrates deficiencies among healthcare providers in following the recommended practices for correctly using PPE during the pandemic. Poor practice in PPE donning and doffing necessitates additional educational and training programs focused on infection control practices., Competing Interests: Conflict of interest statement The authors declare no conflict of interest., (©2021 Pacini Editore SRL, Pisa, Italy.)

Background: Disease-specific quality of life instruments assess the impact of chronic rhinosinusitis on patients' quality of life (QoL). To the extent of our knowledge, there are no Arabic versions of two instruments-the Rhinosinusitis Disability Index (RSDI) and the Chronic Sinusitis Survey (CSS)., Objective: Develop an Arabic-validated version of both instruments, thus allowing its use among the Arabic population., Design: Prospective cross-sectional study for instrument validation., Setting: Tertiary university hospital., Subjects and Methods: This study was conducted between September 2015 and October 2016. We followed the international comprehensive guidelines for translation and cross-cultural adaptation of QoL instruments., Main Outcome Measures: Test-retest reliability, discriminant validity, and responsiveness ability of both the RSDI and CSS Arabic versions., Sample Size: 124., Results: The sample comprised 75 patients diagnosed with chronic rhinosinusitis and 49 healthy control subjects. The Arabic version of both instruments showed high internal consistency (Cronbach's alpha: RSDI=0.97, CSS=.88) and the ability to differentiate between diseased and healthy volunteers (P less than .0001). The translated versions also detected significant change in response to an intervention (P less than .0001)., Conclusion: These Arabic validated versions of the RSDI and CSS can be used for both clinical and research purposes., Limitations: This study was performed in only one tertiary hospital., Conflict of Interest: None.

The aim was to investigate the effect of obesity on academic grades among Saudi female medical students. This cross sectional study was conducted in the Department of Plastic Surgery, College of Medicine, King Saud University, Riyadh, Saudi Arabia during the period November 2014 to June 2015. In all 191 second and third year female medical students with an average age of 21.31 years and body mass indices 15-40 were included. An English language questionnaire was established to obtain the information about age, gender, body mass index, level of study and the academic grades [Grade Point Average-GPA]. Female medical students with BMI 21-25 and 26-30 achieved high GPA while female medical students with higher BMI 31-35 and greater than 36 obtained low GPA. High BMI in female medical students impair the academic performance. The academic institutes must establish extra-curricular physical fitness policies to minimize the obesity and achieve better health and academic outcomes.

Installation of mobile phone base stations in residential areas has initiated public debate about possible adverse effects on human health. This study aimed to determine the association of exposure to radio frequency electromagnetic field radiation (RF-EMFR) generated by mobile phone base stations with glycated hemoglobin (HbA1c) and occurrence of type 2 diabetes mellitus. For this study, two different elementary schools (school-1 and school-2) were selected. We recruited 159 students in total; 96 male students from school-1, with age range 12-16 years, and 63 male students with age range 12-17 years from school-2. Mobile phone base stations with towers existed about 200 m away from the school buildings. RF-EMFR was measured inside both schools. In school-1, RF-EMFR was 9.601 nW/cm² at frequency of 925 MHz, and students had been exposed to RF-EMFR for a duration of 6 h daily, five days in a week. In school-2, RF-EMFR was 1.909 nW/cm² at frequency of 925 MHz and students had been exposed for 6 h daily, five days in a week. 5-6 mL blood was collected from all the students and HbA1c was measured by using a Dimension Xpand Plus Integrated Chemistry System, Siemens. The mean HbA1c for the students who were exposed to high RF-EMFR was significantly higher (5.44 ± 0.22) than the mean HbA1c for the students who were exposed to low RF-EMFR (5.32 ± 0.34) (p = 0.007). Moreover, students who were exposed to high RF-EMFR generated by MPBS had a significantly higher risk of type 2 diabetes mellitus (p = 0.016) relative to their counterparts who were exposed to low RF-EMFR. It is concluded that exposure to high RF-EMFR generated by MPBS is associated with elevated levels of HbA1c and risk of type 2 diabetes mellitus.
