Knowledge and Perception about Health Risks of Cigarette Smoking among Youngsters in Jazan Region, Saudi Arabia.

Context: Cigarette smoking is a global public health concern, particularly in developing countries. Saudi Arabia has a high prevalence of smoking among young individuals, highlighting the need for interventions to address this issue. Aims: This study aimed to evaluate the awareness, attitude, smoking rates, and perception of health risks among young individuals in the Jazan region of Saudi Arabia. The goal was to identify areas for improvement and develop effective strategies to combat smoking and promote healthier lifestyles. Methods and Materials: A cross-sectional survey was conducted at the out-patient department of the College of Dentistry, Jazan University, over a 3-month period. A questionnaire consisting of 15 open-ended questions was administered to eligible patients. Statistical Analysis Used: Statistical analysis was performed using the Chi-squared test with a P- value of <0.05. Results: Out of 300 participants, the majority were males, university students, and non-smokers. Among smokers, electronic cigarettes were the most used form. Starting smoking with friends was a common trend. Females smoked fewer times per day compared to males. Participants expressed concerns about the damaging effects of smoking on health. Conclusions: Targeted interventions and educational programs are needed to address smoking behaviors among young individuals in the Jazan region. Gender-specific interventions, family involvement, and promoting school connectedness are crucial in reducing smoking rates. Graphic health warnings on cigarette packs have the potential to improve knowledge and quitting intentions. Continued research and surveillance are necessary to inform evidence-based policies and interventions to combat youth smoking.

Prevalence and Variation of Medical Comorbidities in Oral Surgery Patients: A Retrospective Study at Jazan University.

BACKGROUND An aged population is susceptible to chronic diseases, which impacts oral surgery treatment procedures. This retrospective study aimed to evaluate the incidence of medical comorbidities in 640 oral surgery patients treated at the College of Dentistry, Jazan University. MATERIAL AND METHODS This single-center observational study investigated medical records of outpatients who visited Jazan University Dental College Hospital in a 1-year period (2018-2019). Patients’ clinical and radiographic archives were screened to obtain relevant data. Categorical and continuous variables were expressed in terms of frequency and mean values, respectively. Differences in variables were statistically analyzed using the chi-square goodness of fit and proportional test, with a probability value P≤0.05 considered significant. RESULTS Analysis of 640 patient records included records of 300 men and 340 women who underwent oral surgery, of whom 176 patients (27.5%), including 97 men and 79 women, had medical comorbidities. The most common comorbidities were endocrine disease (7.03%), cardiovascular disease (6.71%), respiratory disease (4.53%), and hematological disorders (3.43%). Individual diseases that showed higher prevalence were diabetes mellitus (4.68%), hypertension (3.43%), bronchial asthma (2.65%), and anemia (1.4%). Differences by sex were observed in many individual disorders. CONCLUSIONS Outpatients in oral surgery clinics presented a significant variance in the incidence of medical comorbidities, among which diabetes and hypertension were most common. A proper case history is the best preventive measure that helps a surgeon avert medical emergencies and post-surgical complications.

Sudden unexpected death in epilepsy: What Saudi people with epilepsy want to know-A cross-sectional study.

OBJECTIVE: Sudden unexpected death in epilepsy (SUDEP) is a significant cause of mortality in people with epilepsy (PWE), with an incidence of 1 per 1000 members of the population. In Saudi Arabia, no data are available that inform local clinical practitioners about the attitudes of PWE regarding SUDEP. The aim of this study was to investigate the perspectives of Saudi PWE toward SUDEP and to assess their knowledge of SUDEP. METHODS: A cross-sectional questionnaire-based study was conducted at the neurology clinics of King Abdul-Aziz Medical City, Riyadh and Prince Sultan Military Medical City, Riyadh. RESULTS: Of the 377 patients who met the inclusion criteria, 325 completed the questionnaire. The mean age of the respondents was 32.9 ± 12.6 years. Of the study subjects, 50.5% were male. Only 41 patients (12.6%) had heard about SUDEP. Most patients (94.5%) wanted to know about SUDEP, of whom 313 (96.3%) wanted to receive this information from a neurologist. A total of 148 patients (45.5%) thought that the appropriate time to receive information about SUDEP was after the second visit, whereas only 75 (23.1%) wanted to learn about SUDEP during the first visit. However, 69 patients (21.2%) thought that the appropriate time to be informed about SUDEP was when seizure control had become more difficult. Almost half (172, 52.9%) of the patients thought that SUDEP could be prevented. SIGNIFICANCE: Our findings suggest that most Saudi PWE do not know about SUDEP and want to be counseled about their risk of SUDEP by their physicians. Therefore, education of Saudi PWE about SUDEP must be improved.

Quality of web-based Arabic health information on dental implants: an infodemiological study.

BACKGROUND: In the era of the internet, patients seek health information ahead of getting the required treatment. Dental implant, which is among the most sought dental treatments, is not an exception. Incorrect health related information may lead to harmful deeds, so this study sought to assess the quality of web-based Arabic health information on dental implants. METHODS: The following engines were searched: Google ( http://www.google.com ), Yahoo! ( http://www.yahoo.com ), and Bing ( http://www.bing.com ) on 13 January 2022 for specific Arabic terms on "dental implants". The first 100 consecutive websites from each engine were analyzed for eligibility. The eligible websites were assessed using JAMA benchmarks tool, DISCERN tool, and HONcode. An online tool (including FKGL, SMOG and FRE) was used to assess readability of the websites. RESULTS: There were 65 eligible websites, of which only one (1.5%) was HONcode certified. Only 3 (4.5%) websites attained a high score (> 65 out of 80) based on DISCERN tool: The mean DISCERN score was 41.14 ± 12.64. The mean JAMA score was 1.69 ± 1.13; however, only five (7.6%) met all JAMA criteria. The main shortcomings were attributed to not meeting the "Attribution" (54 [83.1%]) and "Authorship" (43 [66.2%]) criteria. The mean grade level of FKGL score was 7.0 ± 4.5. The majority of the websites (60%) scored less than 7, indicating easy content to understand. The mean grade level of SMOG score required to understand a website's text was 3.2 ± 0.6. Around 91% of the websites had reading ease scores ≥ 80, suggesting that the website's content was easy to read. CONCLUSION: Unfortunately, although readable, most of the easily accessible web-based Arabic health information on dental implants does not meet the recognized quality standards.

Kinesio Taping as a Therapeutic Tool for Masticatory Myofascial Pain Syndrome-An Insight View.

Myofascial pain syndrome (MPS) is thought to stem from masticatory muscle hypersensitivity. Masticatory myofascial pain syndrome (MMPS) is characterized by multiple trigger points (MTrPs), also known as hyperirritable points, in taut bands of affected muscles, regional muscle pain, or referred pain to nearby maxillofacial areas like teeth, masticatory muscles or the temporomandibular joint (TMJ). Muscle stiffness, reduced range of motion, muscle weakening without atrophy, and autonomic symptoms may accompany regional discomfort. Multiple treatments have been utilized to reduce trigger points and mandibular function restrictions. As a result of these incapacitating symptoms, MMPS can significantly impair many elements of quality of life. The application of Kinesio tape (KT) is a non-invasive method of treating dormant myofascial trigger points. Utilizing the body's innate capacity for self-repair, this technique entails taping specific regions of the skin. KT alleviates discomfort, decreases swelling and inflammation, enhances or suppresses motor function in the muscles, stimulates proprioception, promotes lymphatic drainage, stimulates blood flow, and expedites tissue recovery. However, studies conducted to assess its effects have frequently yielded contradictory results. To the best of our knowledge, just a few research has looked into the therapeutic effects of KT on MMPS. The purpose of this review is to determine the efficacy of KT as a therapeutic tool for regular treatment or as an adjunct to existing therapy for MMPS based on the evidence presented in this review. To establish KT as a reliable independent treatment option, additional research is necessary to confirm the efficacy of KT techniques and applications, specifically randomized clinical trials.

Dental caries experience among qat chewers in dental college clinics, Jazan, Saudi Arabia.

AIMS: There is a considerable debate on the impact of qat chewing on dental and oral health. Thereby, this study aimed at assessing the dental caries among qat chewers (QC) and non-qat chewers (NQC) who attend outpatient dental clinics, College of Dentistry, Jazan, Saudi Arabia. MATERIALS AND METHODS: A sample of 100 QC and 100 NQC were recruited amongst those attended dental clinics, college of dentistry, Jazan University during the 2018-2019 academic year. Their dental health was assessed by three pre-calibrated male interns using DMFT index. The Care Index, Restorative Index and Treatment Index were calculated. Comparisons between both subgroups were done using independent t test. Multiple linear regression analyses were further conducted to stand on the independent determinants of the oral health among this population. RESULTS: QC were unintentionally older (36.55 ± 8.74 years) than NQC (32.96 ± 8.49 years; P = 0.004). Fifty-six percent of QC reported brushing their teeth compared to only 35% (P = 0.001). NQC with university and postgraduate educational levels were more than QC. The mean Decayed [5.91 (5.16)] and DMFT [9.15 (5.87)] were higher among QC compared to NQC [3.73 (3.62) and 6.7 (4.58); P = 0.001 and 0.001, respectively]. The other indices were not different between both subgroups. The multiple linear regression revealed that qat chewing and age, individually or together, as independent determinants for the dental decay, missing, DMFT and TI. CONCLUSION: Qat chewing habit has a detrimental impact on dental health. It is associated with higher dental caries and missing teeth, and a lower treatment index.

Direct oral anticoagulant: Review article.

Venous thromboembolism (VTE) and atrial fibrillation (AF) is a major burden on the health care system. The average occurrence of venous thromboembolism annually is around 108 per 100,000 person-year. DOACs have transformed treatment of coagulation disorder, and now, it is the leading treatment for stroke prevention in AF and VTE prophylaxis and treatment. For more many years, oral vitamin K antagonists (VKAs) were the drug of choice in managing VTE. VKAs treatment is safe and effective if therapeutic international normalized ratio (INR) maintained on the target. However, achieving a stable, therapeutic international normalized ratio (INR) can be difficult and challenging in the context of drug and food interactions and liver disorder, resulting in undertreatment which increases the risk of thromboembolism or overtreatment which might cause bleeding. Herein, we provide an overview of DOACs indications, use in specific comorbidities, monitoring parameters, perioperative management, and reversal agents.

Knowledge, beliefs, attitude, and practices of E-cigarette use among dental students: A multinational survey.

BACKGROUND: E-cigarette use is a trend worldwide nowadays with mounting evidence on associated morbidities and mortality. Dentists can modify the smoking behaviors of their patients. This study aimed to explore the knowledge, beliefs, attitude, and practice of E-cigarette use among dental students. MATERIALS AND METHODS: This multinational, cross-sectional, questionnaire-based study recruited undergraduate dental students from 20 dental schools in 11 countries. The outcome variable was current smoking status (non-smoker, E-cigarette user only, tobacco cigarette smoker only, dual user). The explanatory variables were country of residence, sex, age, marital status, and educational level. Multiple linear regression analysis was performed to explore the explanatory variables associated with E-cigarette smoking. RESULTS: Of the 5697 study participants, 5156 (90.8%) had heard about E-cigarette, and social media was the most reported source of information for 33.2% of the participants. For the 5676 current users of E-cigarette and/or tobacco smoking, 4.5% use E-cigarette, and 4.6% were dual users. There were significant associations between knowledge and country (P< 0.05), educational level (B = 0.12; 95% CI: 0.02, 0.21; P = 0.016) and smoking status (P< 0.05). The country of residence (P< 0.05) and smoking status (P< 0.05) were the only statistically significant factors associated with current smoking status. Similarly, there were statistically significant associations between attitude and country (P< 0.05 for one country only compared to the reference) and history of previous E-cigarette exposure (B = -0.52; 95% CI: -0.91, -0.13; P = 0.009). Also, the practice of E-cigarettes was significantly associated with country (P< 0.05 for two countries only compared to the reference) and gender (B = -0.33; 95% CI: -0.52, -0.13; P = 0.001). CONCLUSION: The knowledge of dental students about E-cigarette was unsatisfactory, yet their beliefs and attitudes were acceptable. Topics about E-cigarette should be implemented in the dental curriculum.

The Actual Role of Iterative Reconstruction Algorithm Methods in Several Saudi Hospitals As A Tool For Radiation Dose Minimization of Ct Scan Examinations.

Background: Iterative reconstruction algorithm (IR) techniques were developed to maintain a lower radiation dose for patients as much as possible while achieving the required image quality and medical benefits. The main purpose of the current research was to assess the level and usage extent of IR techniques in computed tomographic (CT) scan exams. Also, the obligation of practitioners in several hospitals in Saudi Arabia to implement IR in CT exams was assessed. Material and Methodology: The recent research was based on two studies: data collection and a survey study. Data on the CT scan examinations were retrospectively collected from CT scanners. The survey was conducted using a questionnaire to evaluate radiographers' and radiologists' perceptions about IR and their practices with IR techniques. The statistical analysis results were performed to measure the usage strength level of IR methods. Results and Discussions: The IR strength level of 50% was selected for nearly 80% of different CT examinations and patients of different ages and weights. About 46% of the participants had not learned about IR methods during their college studies, and 54% had not received formal training in applying IR techniques. Only 32% of the participants had adequate experience with IR. Half of the participants were not involved in the updating process of the CT protocol. Conclusion: The results indicate that the majority of radiographer and radiologist at four different hospitals in Saudi Arabia have no explicit or understandable knowledge of selecting IR strength levels during the CT examination of patients. There is a need for more training in IR applications for both radiologists and radiographers. Training sessions were suggested to support radiographers and radiologists to efficiently utilize IR techniques to optimize image quality. Further studies are required to adjust CT exam protocols effectively to utilize the IR technique.

Future Acceptability of Respiratory Virus Infection Control Interventions in General Population to Prevent Respiratory Infections.

Background and Objectives: In both pandemic and non-pandemic situations, nonpharmaceutical public health measures may offer easy, low-cost, and effective means of reducing the spread and impact of acute respiratory infections. It is unknown whether such measures would be acceptable to the Saudi community beyond the current pandemic. Materials and Methods: A validated survey was used to test community acceptance of the measures. Respondents were asked which infection control practices they planned to maintain and which they believed should be policies for the community as a whole after the COVID-19 pandemic has subsided. Results: The survey was completed by 2057 people (95% completion rate), 1486 (72%) of whom were female, 259 (12.5%) of whom were current smokers, and 72 (3.5%) of whom had chronic lung disease. The most prevalent age groups were 18−30 years (933; 45.4%) and 31−40 years (483; 23.5%), with 641 individuals over 40 years old. Of the responses, 93% indicated that they would continue washing their hands more often; 92% wanted both clinicians and patients to wear masks in hospitals; 86% would continue avoiding smoking in indoor and outdoor areas; 73% would continue wearing a face covering on public transportation; 70% indicated that they would continue wearing a face covering in indoor public places. Regarding the respiratory virus infection control measures, 85% (11/13) received significant support (≥70% acceptability level) for continuation as policies in the future. Wearing face coverings outdoors and social distancing outdoors received little support (45% and 66%, respectively). Of the respiratory virus infection control measures, 54% received less support from current smokers than non-smokers (acceptability level < 70%). People with chronic respiratory disease supported 77% of the measures being regarded as policies in the future. Conclusion: The Saudi community supports nonpharmacological respiratory infection control measures that reduce the likelihood of infection. Public health campaigns should target smokers to increase awareness of the importance of these measures in lowering infections. Based on the findings of this study, nonpharmacological treatments should be presented and included in future recommendations for both the public and patients diagnosed with chronic respiratory diseases.

Adherence of Saudi women with epilepsy to folic acid intake in the preconceptional period in two tertiary care hospitals in Riyadh: A cross sectional study.

Antiseizure medication have been associated with an increasing risk of congenital anomalies. Medical authorities recommend taking folic acid during the pre-conceptional period to reduce the risk of congenital malformations in the newborns of women with epilepsy (WWE). In this cross-sectional study, we aimed to measure the adherence of Saudi WWE to folic acid intake. We included WWE visiting outpatient epilepsy clinics in King Abdulaziz Medical City and King Fahad Medical City in Riyadh between September 2017 and August 2018. By consecutive non-probability sampling, we identified 85 patients who met the inclusion criteria of the study. The data were collected by a self-administrated questionnaire. We found that the mean age of the subjects was 33 ± 7.5 years. One third were university graduates. Eighty percent were aware of the role of folic acid in preventing congenital anomalies, and 63.9% were taking it during the preconceptional period. No association was found between educational level and adherence to folic acid intake. In conclusion, adherence to folic acid intake among Saudi WWE is not optimal. More efforts are needed to increase patient adherence to folic acid intake.

Temporal Muscle Cavernous Hemangioma: A Case Report and Literature Review.

Hemangiomas are nonmalignant vascular lesions commonly seen in both the skin and mucosa that rarely occur in skeletal muscles. According to the type of vessel, a hemangioma can be differentiated into capillary, cavernous, or mixed types. The following report describes a case of temporalis muscle hemangioma in a 45-year-old female who presented with painful swelling in the left outer orbital wall, which had been growing in size over the past 12 months. CT scan and MRI revealed a well-demarcated lesion in the temporalis muscle measuring 10 mm × 13 mm × 15 mm. Surgical resection of the lesion was performed, allowing a definitive diagnosis of cavernous hemangioma to be made histologically. As radiological images are mainly inadequate for definitively diagnosing these lesions, surgical intervention is usually required. The recurrence rate differs among the three subtypes; thus, clinical follow-up and radiological imaging as needed are recommended.

Oral health practices and self-reported adverse effects of E-cigarette use among dental students in 11 countries: an online survey.

OBJECTIVES: E-cigarette use has become popular, particularly among the youth. Its use is associated with harmful general and oral health consequences. This survey aimed to assess self-reported oral hygiene practices, oral and general health events, and changes in physiological functions (including physical status, smell, taste, breathing, appetite, etc.) due to E-cigarette use among dental students. METHODS: This online, multicounty survey involved undergraduate dental students from 20 dental schools across 11 different countries. The questionnaire included demographic characteristics, E-cigarette practices, self-reported complaints, and associated physiological changes due to E-cigarette smoking. Data were descriptively presented as frequencies and percentages. A Chi-square test was used to assess the potential associations between the study group and sub-groups with the different factors. Statistical analysis was performed using SPSS at P < 0.05. RESULTS: Most respondents reported regular brushing of their teeth, whereas only 70% used additional oral hygiene aids. Reported frequencies of complaints ranged from as low as 3.3% for tongue inflammation to as high as 53.3% for headache, with significant differences between E-cigarette users and non-users. Compared to non-smokers, E-cigarette users reported significantly higher prevalence of dry mouth (33.1% vs. 23.4%; P < 0.001), black tongue (5.9% vs. 2.8%; P = 0.002), and heart palpitation (26.3%% vs. 22.8%; P = 0.001). Although two-thirds of the sample reported no change in their physiological functions, E-cigarette users reported significant improvement in their physiological functions compared to never smokers or tobacco users. CONCLUSION: Dental students showed good oral hygiene practices, but E-cigarette users showed a higher prevalence of health complications.

Pattern of orthopedic injuries among Victims of Road Traffic Accidents in Aseer region, Saudi Arabia.

BACKGROUND: Road Traffic Accidents (RTA) are one of the most common causes of morbidity and mortality in Saudi Arabia despite preventive measures and programs. The major factors for the increase in the incidence of mortality and morbidity are due to human factors, such as over speeding, not obeying traffic laws, fatigue, and driving before the legal age. In this study, we aim to report the pattern of orthopedic injuries (OIs) from RTA in the south-western region of Saudi Arabia and to explore the healthcare outcomes of OIs. METHOD: This is a retrospective, record-based, case series study including RTA patients who were admitted to the Emergency Department (ED) at a tertiary hospital in the south-western region of Saudi Arabia. The data was collected for 531 admitted RTA patients with OIs over for five years from May 2011 to May 2016. Patients who were 15 years of age or above were included in this study. The data were analyzed using the statistical package for social science (SPSS) version 21. RESULTS: A total of 531 patients were included with an age range between 15 and 90 years with an average age of 29 ± 2 years. Most of the population was male constituting 91.3% of the sample while 91.9% of the sample were Saudis. About 75% of the OIs had simple fractures and complex fractures were recorded among 10.2% of the cases. About half of the cases (52%) had lower limb fractures and 32% had upper limb fractures. CONCLUSIONS: RTA and the resultant OIs, death, and permanent disabilities cause a tremendous burden on economic resources and should be of concern for local authorities. More attention and regularities should be paid to avoid life-threatening driving behaviors.

Oral and Dental Complications of Radiotherapy for Head and Neck Cancer: Knowledge of Dental Practitioners in Saudi Arabia.

OBJECTIVES: Toxicities of the oral soft and hard tissues due to the radiotherapy of the head and neck cancer can potentially lead to interruptions of cancer treatment and/or dose reduction, resulting in poorer outcomes. The aim of this study was to assess the knowledge of dental practitioners in Saudi Arabia about oral and dental assessment for and complications of radiotherapy of head and neck cancer. MATERIALS AND METHODS: An online, already validated, self-administered questionnaire was sent via an online link through WhatsApp groups and other Social Media platforms to reach out to the majority of targeted samples (dental practitioners working in Saudi Arabia). Responses were statistically described and analyzed based on the different grouping factors: gender, specialty, working sector, region of work and experience. RESULTS: There were 370 respondents, 257 (69.5%) of them were males. Most of the respondents were general dental practitioners [144 (38.9%)], The percentages of the correct answers range from as low as 26.2 to as high as 97%. The per cent of correct answers by the respondents in 18 out of 31 questions was above 75%. Females, dental specialists (specifically prosthodontics), working in public sectors and in the central and western regions of Saudi Arabia were associated with higher levels of knowledge. CONCLUSION: Our results show highly variable knowledge of dental practitioners on oral and dental assessment for, and complications and management of radiotherapy to the head and neck area; that knowledge seems to fluctuate considerably with gender, experience, work sector and specialty.

Rapid single-molecule detection of COVID-19 and MERS antigens via nanobody-functionalized organic electrochemical transistors.

The coronavirus disease 2019 (COVID-19) pandemic has highlighted the need for rapid and sensitive protein detection and quantification in simple and robust formats for widespread point-of-care applications. Here, we report on nanobody-functionalized organic electrochemical transistors with a modular architecture for the rapid quantification of single-molecule-to-nanomolar levels of specific antigens in complex bodily fluids. The sensors combine a solution-processable conjugated polymer in the transistor channel and high-density and orientation-controlled bioconjugation of nanobody-SpyCatcher fusion proteins on disposable gate electrodes. The devices provide results after 10 min of exposure to 5 µl of unprocessed samples, maintain high specificity and single-molecule sensitivity in human saliva and serum, and can be reprogrammed to detect any protein antigen if a corresponding specific nanobody is available. We used the sensors to detect green fluorescent protein, and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and Middle East respiratory syndrome coronavirus (MERS-CoV) spike proteins, and for the COVID-19 screening of unprocessed clinical nasopharyngeal swab and saliva samples with a wide range of viral loads.

Descriptive Patterns of Deafness Among Pre-School Saudi Children Aged Two to Five Years Visiting Neurology Clinic From 2012 to 2017.

Background Early childhood years are very important and crucial periods for developing different developmental milestones. Hearing loss is considered to be one of the most commonly detectable problems, which often goes unnoticed or not given proper attention due to the lack of screening modalities or the inability of parents or guardians to recognize it in early stages. Therefore, it is necessary to determine the pattern of differences pertaining to hearing loss among pre-school children of various age groups to better approach this issue in a systemic and fundamental manner, so that better care and treatment can be provided to children suffering from deafness. Methods This study involved a descriptive, retrospective chart review in two hospital settings, and it was conducted at the department of physiology (neurophysiology) of King Abdulaziz and King Khalid University Hospitals at the King Saud University (KSU) in Riyadh during the period of 2012-2017. A total of 324 pre-school Saudi children from the age of two to five years were involved and tested by brainstem auditory evoked potentials (BAEPs) to assess deafness. Results A total of 324 patients underwent the BAEP test; of them, 199 (61.4%) were males and 125 (38.6%) were females. Regarding the age groups, the most common age group was that of two-year-olds with 117 (36.1%) participants, followed by three-year-olds with 80 (24.7%) children, four-year-olds with 73 (22.5%) patients, and five-year-olds with 54 (16.7%) participants. Furthermore, there were 220 (67.9%) patients with sensorineural hearing loss (SNHL), 92 (28.4%) with conductive hearing loss (CHL), four (1.2%) with mixed hearing loss (MHL), and eight (2.5%) with normal audiometry. The normal hearing threshold was determined to be 20 dB, and the mean value for the hearing threshold of the SNHL in the right ear was found to be 43.45 ± 25.85, while the left-ear mean value was 44.54 ± 28.78. The mean value of the hearing threshold in CHL of the right ear was 50.96 ± 22.23, while that of the left ear was 47.85 ± 22.74. Lastly, the mean value of the hearing threshold in MHL of the right ear was 80.00 ± 21.21, while that of the left ear was 73.75 ± 18.87. Conclusion SNHL was the most common type (67.9%) of pre-school hearing loss in Saudi Children attending the neurophysiology clinic at KSU hospitals between 2012-2017, while MHL constituted the most severe cases.

Novel corona virus disease (COVID-19) awareness among the dental interns, dental auxiliaries and dental specialists in Saudi Arabia: A nationwide study.

BACKGROUND: Dental health care workers (DHCW's) are invariably at a higher risk of contracting COVID-19. The objectives were; to investigate the current knowledge on COVID-19 among the DHCW's; and to conduct quasi-experiment among the DHCW's who were unaware of the disseminated COVID-19 information. METHODS: A nationwide cross-sectional study targeting dental interns, auxiliaries, and specialists with a two-staged cluster sampling technique was performed. A 17-item questionnaire was subjected to reliability and validity tests before being administered. The participants for quasi-experiment were separated from the original sample after their initial response. Chi-square test assessed responses to knowledge statements between the participants. Difference in mean knowledge scores between the categories of DHCW's and sources of COVID-19 information was assessed using ANOVA. Data from the quasi experiment (pre vs post knowledge intervention) was subjected to paired t-test. Percentage of DHCWs providing correct or wrong responses to each knowledge statement at baseline and after 7 days were compared using McNemar test. RESULTS: The overall sample consisted of 706 (N) participants, and the DHCW's with no prior knowledge on COVID-19 (N=206) were part of the quasi experiment. Findings from cross-sectional study revealed that knowledge was significantly (p<0.05) related to the qualification level (interns vs auxiliaries vs specialists). However, the difference in the source of information (WHO/CDC vs Journal articles vs MoH) did not demonstrate any effect. Number of participants with correct responses to knowledge questions had significantly (p<0.05) increased after intervention. Also, the overall mean knowledge score (10.74±2.32 vs 12.47±1.68; p<0.001) had increased significantly after the intervention. CONCLUSION: In conclusion, the basic knowledge on COVID-19 among the DHCW's in Saudi Arabia is acceptable. Timely dissemination of information by the Ministry of Health, Saudi Arabia had a positive impact on the COVID-19 knowledge score of the DHCW's.

Risk Factors and Predictors of Severe Dengue in Saudi Population in Jeddah, Western Saudi Arabia: A Retrospective Study.

This study was performed to determine the risk factors and predictors of severe dengue fever (SDF) in Saudi population in Jeddah, Western Saudi Arabia. This 7-year retrospective study included children and adults with confirmed dengue from 2010 to 2016. Demographic, clinical, laboratory, serological, and virologic data were collected. Comparative analyses were performed between pediatric and adult SDF cases defined according to the WHO 2009 dengue classification. During the study period, dengue was confirmed in 17,646 cases with predominant infection of adults (6.5 times that of children) and males (3.8 times that of females). May and June were associated with 43.9% of total dengue cases. All 56 pediatric and 187 adult SDF cases were hospitalized. At least one warning sign of severe illness was present in 92.2% of total SDF cases. Mortality rates were 8.9% and 10.7% of pediatric and adult SDF cases, respectively. Multiple logistic regression detected that the most significant risk factors and predictors of SDF in adults versus children were significantly more secondary dengue infection (adjusted odds ratio [AOR]: 2.20, 95% CI: 1.09-4.44, P = 0.02), significantly less clinical fluid accumulation (AOR: 0.17, 95% CI: 0.07-0.44, P < 0.001) and significantly less neutropenia (AOR: 0.41, 95% CI: 0.17-0.97, P = 0.04). This was the first large multicenter study evaluating SDF in Saudi population and considering the WHO 2009 dengue classification, which showed predominant infection of adults and males with dengue, few SDF cases with low mortality and highlighted predictors of SDF in adults versus children. Consideration of warning signs for severe dengue may result in hospital admission, prompting closer monitoring, timely and proper interventions and reduced mortality in SDF cases.

A comparative evaluation of 4% articaine and 2% lidocaine in mandibular buccal infiltration anesthesia: A clinical study.

BACKGROUND: To compare 4% articaine and 2% lidocaine local anesthetics in achieving pulpal anesthesia of the lower first permanent molar teeth objectively, and to assess and compare lip and lingual mucosa numbness subjectively. MATERIALS AND METHODS: All subjects received 1.7 ml of any one anesthetic in the mucobuccal fold adjacent to mandibular first molar teeth; the same individuals received the second infiltration at least 1 week after the first. Later, comparisons for pulpal anesthesia, lip and lingual mucosa numbness between these two anesthetics solutions were made. RESULTS: Articaine showed significant results with P = 0.006 in achieving pulpal anesthesia objectively, when compared with lidocaine. Articaine also showed very high significant results subjectively with P = 0.0006 in achieving lip numbness, when compared with lidocaine. But the results in achieving lingual mucosa numbness with articaine subjectively was not significant with P = 0.01, when compared with lidocaine. CONCLUSION: Endodontic and operative treatments are one of the most common oral non-surgical procedures done under local anesthesia. The diversity of anesthetic substances currently available on the market requires dental professionals to assess the drug both by its pharmacokinetic and also by its clinical characteristics during dental treatments. Our study used 4% articaine, which is available in the market, for comparison with 2% lidocaine. Further studies are required to use an equal concentration of solutions to achieve more accurate results.
