Purpose To determine the prevalence of concha bullosa (CB) and nasal septal deviation (NSD) and their impact on maxillary sinus volume (MSV). Materials and Methods Cone-beam computed tomographic (CBCT) images of 106 Emirati people were used in this study. The direction and angle of septal deviation were calculated. The presence of CB, which could be unilateral, contralateral, or bilateral in relation to the direction of NSD, was also recorded. MSV was measured using reconstructed Digital Imaging and Communication in Medicine images on Dolphin 3D imaging software version 11.8 premium (Dolphin Imaging, Chatsworth, CA, USA). P values <0.05 were considered to indicate statistical significance. Results CB was detected in 37.7% of the sample; 20.7% of the sample showed single unilateral CB and 16.6% had single bilateral CB. NSD was seen in 74.5% of the sample. In the participants with CB, 45.5% showed mild deviation, 34.4% showed moderate deviation, and only 12.5% showed severe septal deviation. CB, but not NSD, was associated with significantly higher MSV on the affected side ( P =0.001). Conclusion Although NSD was observed in more than two-thirds of the sample and CB was present in more than one-third of the sample, only CB had a significant impact on MSV.
Objective To determine the relationship and prevalence of taste and smell dysfunction in patients with COVID-19 in the UAE population. Methods Enrolled participants were interviewed online via a phone call after obtaining their informed consent. Quantification of smell, taste, and other sensations before, during, and after COVID-19 infection was correlated with the severity of COVID-19 symptoms. Results A total of 500 (mild – severe) COVID-19 patients completed the survey. A total of 26.4% were asymptomatic, and 21.4% were classified as paucisymptomatic with less severe symptoms. Almost equal proportions of the studied population experienced extreme taste sensation reductions (43%) and loss of smell sensation (44%). Statistically significant drastic decreases in smell and taste senses were seen among younger ages. The magnitude of reduction in both sense changes increased steeply from the asymptomatic group to the paucisymptomatic group to the symptomatic group . Conclusion Sudden anosmia or ageusia needs to be recognized for early detection of COVID-19 infection to identify otherwise hidden carriers, thus favoring an early isolation strategy that will restrict the spread of the disease.
Background: In Qatar, prevalence of metabolic components is significantly higher compared to other countries. It is therefore urgent to understand the prevalence of metabolic syndrome (MetS) with the goal of identifying etiologic factors in Qatar. This study was undertaken to estimate the prevalence of MetS, by age, gender and nationality within primary care settings in Qatar. In addition, it determined the independent effects of risk factors on the prevalence of MetS. Methods: A cross-sectional study design was used. Data for individuals aged ≥18 and who visited a publicly funded primary health centre in Qatar during 2017 were extracted from electronic medical records and analysed. Results: The findings showed that the prevalence of individual MetS components ranged between 48.5-60.3%. Overall prevalence of MetS was 48.8% (N = 62,492) in the study population. Prevalence of MetS increased with age. 50.3% of the population within the 40-49 year age group had MetS. In this age band, individuals were 5.1 times more likely of having MetS compared to the 18-29 year age group. MetS was slightly more prevalent in men (56 .7%) compared to women (42.5%). However, men were 1.33 times more likely of having MetS compared to women. The prevalence of MetS ranged between 20.6-60% across nationalities. It was most prevalent in Southern Asians (60%), followed by Northern Africans (50.7%) and Western Asians (excluding Qatar) (46.8%). Prevalence of MetS in Qataris was 43%. Southern Asians, Northern African and Western Asians were 1.73, 1.38 and 1.17 more likely to have MetS compared to Qataris. Conclusions: The study provides essential epidemiological information required by decision makers. Although not nationally representative, this study is suggestive of a higher prevalence of MetS among a younger population, men and in Southern Asian, Northern African and Western Asian nationalities. Prevention, treatment and control of MetS is a public health problem in Qatar. More studies are needed to establish which public health interventions are likely to be effective in Qatar.
BackgroundThe first COVID-19 cases in Qatar were reported on 29th of February 2020. As the epidemic progresses, essential epidemiological information is needed to facilitate monitoring of COVID-19 in the population and plan pandemic response in Qatar.AimThe primary aim of this cross-sectional study is to estimate the point prevalence of COVID-19 in Qatar’s primary care registered population.Design and SettingsA cross sectional study design will be utilized. One publicly funded health centre from each of three geographical regions in Qatar will be identified as a study location and set up to facilitate a drive through for the study.MethodPHCC is publicly funded and the largest primary care provider in Qatar. The study will include randomly selected individuals from the full list of Primary Health Care Corporation’s (PHCC)registered population on its electronic medical records system. The sample selection will be done using a proportional to size sampling technique stratified by age, gender and nationality representative of the overall PHCC registered population. Considering the total population registered in PHCC a sample of 2080 is proposed. A questionnaire will be administered to collect sociodemographic information and a nasal and throat swab sample will be taken. Data will be analysed to report overall symptomatic and asymptomatic point prevalence of COVID-19.ConclusionThis study, with the help of a randomly selected representative sample from Qatar’s primary care registered population, will provide results which can be applied to the entire population. This study design will closely represent a real-world scenario of the outbreak and is likely to provide important data to guide COVID-19 pandemic planning and response in Qatar.
