RESUMO
INTRODUCTION: Acne vulgaris is one of the most prevalent inflammatory conditions in the world that primarily affects teenagers. Its prevalence and the contributing factors vary across different regions and populations. Genetic predisposition, hormonal influences, dietary habits, lifestyle choices, and environmental factors are believed to be significant contributors. METHODS: This was a cross-sectional study involving 419 participants from the Jazan region, Saudi Arabia. The study employed non-probability convenience sampling techniques. Data were collected through online questionnaires and analyzed using Statistical Product and Service Solutions (SPSS, version 27; IBM SPSS Statistics for Windows, Armonk, NY). RESULTS: The study found that acne prevalence was high, affecting more than half (66.8%) of the participants, with mild severity reported by 51.8%. Pimples were most commonly found on the face (65.2%), followed by the back (45.3%) and chest (29.6%). Participants with oily skin had twice the likelihood of acne compared to those with dry skin (OR=2.14). Increasing age was associated with a 5% decrease in acne risk per year. Significant associations were found for age (p=0.010), female gender (p=0.017), and oily skin (p<0.001) with acne development. CONCLUSION: The study found a high prevalence rate of acne vulgaris among the young population in the Jazan region, Saudi Arabia. Age, female gender, and having oily skin were predictors for developing acne vulgaris. Complications such as acne scarring and psychological impacts such as shyness underscore the significant burden of acne on social and psychological well-being. Enhanced treatment and improved quality of life necessitate heightened awareness campaigns concerning acne vulgaris, its treatments, and associated complications, as revealed by the study.
RESUMO
BACKGROUND: Pulmonary embolism (PE) is a common acute life-threatening cardiovascular disorder. It is the third most common cause of hospital-related death and early detection and management of PE are crucial. The study aimed to evaluate the association between vital signs and laboratory investigations with PE. METHODS: This is a retrospective, hospital records-based, observational study, conducted among patients who were admitted to the emergency department of King Saud Medical City in Riyadh, Saudi Arabia with a suspected diagnosis of PE during the period of March 2021 to March 2022. Data were collected by searching patients' files and recording demographic data, and information about the clinical presentation, workup, and outcome. Data were entered and analyzed using SPSS version 26 (IBM, Armonk, NY), utilizing Chi-square statistics to test differences between groups, and logistic regression analyses to identify predictors of PE. RESULTS: The study included 92 patients, with a preponderance of females (70.7%), and those aged 40-60 years (51.1%). Diabetes mellitus (44.6%), and hypertension (30.4%) were the most common comorbidities among others, while shortness of breath (SOB) (83.7%), and chest pain (44.6%) were among the most commonly reported symptoms. A majority of patients had tachycardia (64.1%), while about half had low oxygen saturation (51.5%), and nearly one-third had tachypnea (29.3%), which was more predominant among those not diagnosed with PE. Logistic regression analysis revealed that SOB, respiratory rate, and oxygen saturation were the only significant predictors of PE. CONCLUSION: Although being an integral part of the initial assessment in the hospital, measuring the vital signs is not always reflective of the likelihood of PE, and they should not be the only metric relied upon to make decisions about treatment approaches in patients with PE. Physicians should ensure the employment of evidence-based clinical prediction rules and guidelines when diagnosing and managing PE.
