Central Corneal Thickness of a Saudi Population in Relation to Age, Gender, Refractive Errors, and Corneal Curvature.

Background In this study, we aimed to investigate the relationship between central corneal thickness (CCT) and age, gender, refractive errors, and corneal curvature in a Saudi population. Methodology In this randomized, hospital-based, retrospective study, data were collected from Dr. Sulaiman Al Habib Hospital and Imam Medical Center, Riyadh. A total of 1,005 eyes were included and recruited from patients referred to the refractive surgery clinic for Lasik assessment. The study included patients aged between 17 and 57 years with no history of any ocular pathology, eye surgeries, and systemic disease, as well as all groups with stable refractions. The identifying data were the age and gender of the patients, as well as their CCT, refraction, and corneal curvature. CCT and corneal curvature were measured by ultrasound pachymeter Pentacam. Results The distribution of CCT was 543.81 ± 34.47 µm. A significant difference in the mean CCT was observed across different refractive errors (p = 0.004). Patients with astigmatism had the lowest CCT, followed by myopic and hyperopic patients. An association between the spherical equivalent of patients with myopia and CCT (p = 0.001) was noted. Conclusions In the Saudi population, we found no significant association between mean corneal curvature and CCT in all three groups. Spherical equivalent in myopic patients was significantly associated with CCT. A significant difference in the mean CCT was observed across different refractive errors. There was a significant negative and weak correlation between age in myopic and astigmatism patients and CCT. Gender was significantly associated with CCT in patients with astigmatism.

Attitude and Perception Toward Taking Selfies and Using Filters and Their Relationship With Blepharoplasty.

BACKGROUND: Due to the general increase in the use of social media, the increasing popularity of taking selfies and using filters, we found it essential to examine the effect of these behaviors on the perception and attitude toward blepharoplasty. AIM: This article was conducted to assess participants' attitudes and perceptions toward taking selfies and using filters and their relation to blepharoplasty. METHODS: This study was an observational cross-sectional study undertaken in Saudi Arabia. The study targeted all adults in Saudi Arabia. The study subjects are adults living in Saudi Arabia who consented to participate in the study and have filled out the questionnaire fully between January and April 2022 while meeting the inclusion and exclusion criteria. A convenient sampling technique was used for data collection. The Chi-square test was used to test for association. RESULTS: A total of 466 participants were included in the study. (94.6%) of the participants reported taking selfies, with varying frequencies, with Snapchat being the most commonly used application (82.5%). Moreover, 87.05% of the participants reported using filters, and 96.08% of those who use filters used them from Snapchat. 45.5% of the participants reported comparing their eyelids with others' when seeing their selfies, 50.6% reported thinking that taking a selfie has a role in making a decision to undergo blepharoplasty, and 47.6% reported thinking that using filters has a role in making a decision to undergo blepharoplasty.  Conclusion: This study reflected a notably high rate of taking selfies and using photo filters. The participants' assessment toward the impact of taking selfies and using filters on the decision to undergo blepharoplasty was observed to be moderate. Females were observed to have significantly higher rates of thinking that taking pictures and using filters influence the decision to undergo blepharoplasty compared to males.

Suicide Attempts by Poisoning: An Experience From a High-Volume Emergency Department.

Background There has been a tremendous increase in self-poisoning behavior worldwide, with different trends depending on cultural and geographic aspects. Objectives Our study aims to assess the trends, outcomes, and predictors in patients of suicide attempts by poisoning at King Abdulaziz Medical City (KAMC) ED. Materials and methods A retrospective cohort study took place at KAMC. Frequencies and percentages were used to display categorical variables. Minimum, maximum, mean, and SD were used to display continuous variables. Chi-squared test and independent t-test were utilized to test for factors associated with suicidal intention. Results A total of 130 cases were identified. The participants were mostly females (73.8%, n = 96). Most of the participants were pediatric patients (57.7%, n = 75). The most consumed agents were acetaminophen in 59 (45.83%) and non-steroidal anti-inflammatory drugs (NSAIDs) in 22 (16.92%). The ICU admission rate was 8.5% (n = 11). The management for both populations was unspecific, involving observation, supportive measures, and symptomatic treatment. BMI (p < 0.001), gender (p < 0.001), age (p = 0.012), and a history of neuropsychiatric disorders (p < 0.001) were associated factors. Conclusion It is crucial that the trends and risk factors of self-poisoning suicide attempts are identified to provide support to those in need. Several variables of interest were noted since the two most observed agents share several key features, such as accessibility and availability. However, contradicting literature reports warrant further investigation to confirm or negate the evidence.

Prevalence of Dry Eye Disease and Its Risk Factors Among the General Population of Saudi Arabia: A Cross-Sectional Survey.

BACKGROUND: Dry eye disease is a multifactorial chronic disorder of the ocular surface, which leads to symptoms of discomfort and distress. Dry eye disease is a global health concern and is one of the most frequent ocular diseases encountered in an ophthalmology clinic. The estimated prevalence of dry eye disease in the literature ranged from 7.4% to 93.2%. Saudi Arabia's population, especially in the eastern province, is at great risk of developing dry eye disease, however, there is hardly any nationwide study that assesses the prevalence of dry eye disease among the general population and its risk factors. AIM: The aim is to estimate the prevalence of dry eye disease and determine its risk factors among the general population of Saudi Arabia. METHODS: This study was a cross-sectional study conducted on the general population of Saudi Arabia between September 2022 and November 2022. A convenient sampling technique was deployed for participant recruitment, where a self-administered questionnaire was created and dispersed to the general population all over the country with an invitation to participate in the study. Dry eye disease prevalence was assessed using Ocular Surface Disease Index survey. The Chi-square test was used to test for factors associated with the prevalence of dry eye disease, and undiagnosed dry eye disease. Multivariate logistic regression was also used to determine risk factors for dry eye disease. RESULTS: A total of 1,381 participants were included in this study. The prevalence of dry eye disease among the general population of Saudi Arabia was observed to be (17.5%). Among the participants (11%) had mild dry eye disease, (4.7%) had moderate dry eye disease, and (1.7%) had a severe dry eye disease. Among those observed to have a dry eye disease, (58.09%) were not previously diagnosed. The following factors were observed to be significantly associated with having dry eye disease, being female, having thyroid disease, having systemic lupus erythematosus/rheumatoid arthritis, using antidepressants, using antihistamine/decongestants, using electronic devices for a prolonged time, using contact lenses, having a history of eye surgery, history of conjunctival/eyelid infection, and history corneal abrasions/erosions/ulceration. CONCLUSION:  This study revealed that the prevalence of dry eye disease among the general population of Saudi Arabia is notably lower than what was observed in other local studies and similar to what was found in some global studies. Adjusted binary multivariate logistic regression revealed that the risk factors were only: being female, using antidepressants, using antihistamines/decongestants, and prolonged use of electronic devices.

The Association Between Admission Sources and Outcomes at a Pediatric Intensive Care Unit in Al-Ahsa, Saudi Arabia: A Retrospective Cohort Study.

Objectives In this study, we aimed to examine the association between sources of admission (either intra-hospital transfers or ED admissions) in pediatric intensive care units (PICUs) and the discharge rate, mortality rate, and referral over a period of three years. We also sought to identify the independent predictors of discharge and mortality rate in the study population. Patients and methods This was a retrospective cohort study involving the analysis of 2,547 patients' data collected from the Pediatric Intensive Care Registry of a secondary care community hospital. We included patients admitted to the PICU from January 1, 2016, till December 31, 2018, who were aged 0-14 years with a specific diagnosis, recorded source of admission, and clear outcome. Data were collected, coded, and analyzed using the SPSS Statistics software (IBM, Armonk, NY) and STATA software (StataCorp, College Station, TX). Results Of the included patients, 1,356 (53.2%) were males, and 1,191 (46.8%) were females. Infants were associated with an increased risk of a long stay in the hospital [relative risk ratio (RRR)=5.34, 95% CI: (1.28, 22.27)] and mortality [RRR=3.56, 95% CI: (1.41, 8.95)] compared to older children. Similarly, neonates were associated with a higher risk of mortality [RRR=2.83, 95% CI: (1.05, 7.65)]. Patients who were admitted through ED were associated with a lower risk of a long-stay [RRR=0.56, 95% CI: (10.36, 0.87)] and mortality [RRR=0.68, 95% CI: (0.49, 0.95)] compared to intra-hospital transfers. Concerning the admission date, all time periods were associated with a lower risk of mortality compared to the period of October-December. Conclusion Our findings showed that the age of patients, source of admission, and date of admission might be used as independent predictors for determining the outcome of admissions, including discharge and mortality rates. Further studies are required to confirm these findings.

Prevalence and Predictive Factors for Leg Ulcers in Sickle Cell Disease Patients in Saudi Arabia: A Cross-Sectional Observational Study.

Introduction Saudi Arabia has a high prevalence of sickle cell disease (SCD). Leg ulceration is one of the complications associated with SCD. There is a gap in the literature in regard to the prevalence of leg ulcers among SCD patients in Saudi Arabia. Objectives The primary objective of this study was to evaluate the lifetime prevalence of leg ulcers in SCD patients in our population and to study the predictive factors of leg ulcers by using sociodemographic factors, clinical manifestations of SCD, and other relevant factors like hydroxyurea. Methods A cross-sectional study design was utilized. Data collection was done using an electronic survey to collect self-reported information for the prevalence of leg ulcers and possible associated factors. The survey was distributed using social media platforms. Chi-square test was used to test for the presence of an association between having leg ulcers and sociodemographic variables as well as SCD related history. Furthermore, binary logistic regression was utilized to determine factors predicting the incidence of leg ulcers among SCD. Results A total of 790 valid responses were included in the study. Among these, 646 were included in the analysis of leg ulcers prevalence. From them, 52 (8%) SCD patients reported a history of leg ulcers. The male to female ratio was (9.7% vs 7.2%). The age group most affected by leg ulcers was those older than 50 (16.7%). There was no significant association between a history of leg ulcers and sociodemographic variables. The only predictive factors for leg ulcers were having six to eight vaso-occlusive crises per month and having more than eight vaso-occlusive crises per month. Conclusion Leg ulcers among SCD patients in Saudi Arabia were considerably prevalent (8%). There was no statistically significant correlation between leg ulceration and sociodemographic variables. Leg ulcers were more likely in patients with a history of highly frequent vaso-occlusive crises. No association was found between the incidence of leg ulcers and other complications of sickle cell disease or hydroxyurea.
