Background: Propofol is a key component of contemporary anaesthesia due to its rapid onset and recovery. Despite decades of research, the fundamental studies shaping its clinical use have never been fully mapped. This study provides a citation-based landscape by identifying and analysing the top 50 most cited articles on propofol use in anaesthetic induction, highlighting key developments, topics, and influential authors. Methods: We performed a bibliometric analysis using the Web of Science with the keywords “propofol” and “anaesthesia,” without year restrictions. Articles were screened for relevance focusing on efficacy, safety, and innovations. The top 50 articles by citation count were selected. Data on citations, publication metrics, geographic origin, study design, and level of evidence were extracted and analysed descriptively. Results: The 50 papers totaled 5,252 citations (mean: 104.1; h-index: 50). The top 10% accounted for 40% of citations, largely from European research. Randomized controlled trials comprised 46%, establishing basic safety,... Continue Reading

Background: Unplanned emergency department (ED) readmissions within 30 day remain a major challenge in geriatric care, contributing to increased morbidity, mortality, and healthcare utilization. The triage risk screening tool (TRST) is frequently used to identify older adults at risk of adverse outcomes. However, its predictive accuracy at the conventional cutoff score of ≥2 remains uncertain, raising concerns about its standalone reliability. To systematically evaluate the diagnostic performance of the TRST (cutoff ≥2) in identifying elderly inpatients at risk of unplanned 30-day ED readmissions.Methods: A systematic review and meta-analysis were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. Searches were performed in PubMed, Scopus, Embase, Web of Science, and the Cochrane Library. Eligible studies included cohort designs assessing the TRST in adults aged ≥65 years for predicting 30-day unplanned ED readmissions. Pooled estimates of sensitivity, specificity, diagnostic odds ratio (DOR), and likelihood ratios were obtained... Continue Reading

Background: Tension-type headache (TTH) is the most prevalent neurological disorder globally, affecting over 2 billion individuals and posing a substantial public health and socioeconomic burden. Although pharmacological treatments, such as non-steroidal anti-inflammatory drugs, offer symptomatic relief, concerns regarding long-term efficacy and medication overuse have driven interest in physical therapy as an alternative or adjunctive intervention.Methods: In line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search from inception to December 2024 was conducted in the following electronic databases: PubMed, Google Scholar, Web of Science, the Cochrane Library, and DOAJ. Randomized controlled trials investigating the effect of physiotherapy on TTH were included.Results: Fifty-one randomized controlled trials involving 3,404 participants were included in this review. The studies investigated various physical therapy interventions, including manual therapy, therapeutic exercise, and multimodal approaches. The majority of the included studies demonstrated statistically significant improvements in headache intensity, frequency, and duration compared... Continue Reading

Background: Dengue fever (DF) is caused by the dengue virus, which manifests with systemic features such as fever, malaise, and headache. More than 50% of cases present with a variety of skin lesions.Case Presentation: We present a series of three cases that presented to the clinic with fever associated with gastrointestinal symptoms, including nausea, vomiting, and abdominal pain. Other systematic reviews were unremarkable. The patients subsequently developed a pruritic skin rash characterized by diffuse confluent erythema with petechiae and rounded islands of sparing. After excluding alternative etiologies such as malaria, HIV, and hepatitis C, all three patients were diagnosed with DF.Conclusion: This case series highlights the presence of a characteristic rash in DF. We emphasize the clinical description of this cutaneous manifestation, which is not well-described in previous literature. Although cutaneous manifestations are common in dengue, identifying these specific rash patterns can contribute to accurate and early diagnosis. Patients presenting... Continue Reading

Background: Cardiogenic shock (CS) is the leading cause of mortality in ST-segment elevation myocardial infarction (STEMI). Patients with acute coronary syndrome in Saudi Arabia present a decade younger than Western cohorts and have a higher diabetes burden, yet contemporary local data on CS are limited. We aimed to determine the incidence, characteristics, and predictors of CS in a Saudi STEMI cohort.Methods: Single-center retrospective cohort study of consecutive adult patients with acute STEMI admitted to King Abdulaziz Cardiac Center, Riyadh, from January 2019 to December 2024. CS was defined by the SHOCK trial criteria. Univariate and multivariate logistic regression identified independent predictors.Results: A total of 878 patients were included (mean age 57.2 ± 13.6 years; 86.6% male); 80 (9.1%) developed CS. Compared with patients without CS, those with CS had a higher prevalence of dyslipidemia (58.8% vs. 44.6%, p = 0.016) and ventricular arrhythmia (17.5% vs. 5.5%, p < 0.001), higher...

Background: Wearable devices such as smartwatches are increasingly used for self-monitoring of physical activity; however, evidence regarding their association with physical activity levels in Middle Eastern settings remains limited. This study examined the relationship between smartwatch use and physical activity among adults in Saudi Arabia, using the World Health Organization Global Physical Activity Questionnaire.Methods: A cross-sectional online survey was conducted between August 2024 and February 2025 among Saudi adults aged ≥18 years (n = 1,082), recruited through social media platforms. Data collected included sociodemographic characteristics, smartwatch ownership and usage patterns, and physical activity quantified as metabolic equivalent task minutes per week (MET-minute/week). Multivariable linear regression models were used to identify factors independently associated with physical activity level.Results: The mean participant age was 27 ± 11 years, and 51% were female. Overall, 56% reported smartwatch use, with Apple Watch being the most commonly reported device (40.8%). Smartwatch users had higher physical... Continue Reading

Background: Herbal medicine use has become an area of interest due to the dependence on evidence-based medicine. In Saudi Arabia, medical curricula focus on evidence-based medicine, raising questions about the influence of modern medicine teaching on students’ use of herbal remedies. However, no previous study has been conducted in the Eastern Region of Saudi Arabia, particularly in Al-Ahsa. Methods: A cross-sectional study was conducted among 332 medical students at King Faisal University using a structured questionnaire adapted from a previous study. The questionnaire assessed herbal medicine use and perceptions towards it. Data were collected electronically and analyzed using SPSS version 29. Results: The majority of students reported prior use of herbal medicine (82.2%), and 54.5% expressed interest in it. Herbal medicine was used for both therapeutic and cosmetic purposes. Additionally, 41.9% of students reported that sometimes they avoid manufactured medicine in favor of herbal remedies, and 33.7% believed that herbal... Continue Reading

Background: Hair tourniquet syndrome is a potentially serious condition in which a strand of hair or thread tightly encircles a body part, leading to progressive swelling and possible ischemia if not promptly recognized and treated. Management depends on the depth and severity of the constriction, ranging from chemical dissolution or simple mechanical removal to more invasive techniques when the fiber is deeply embedded.Case presentation: A 24-day-old female infant presented with a 4-hour history of persistent irritability and inconsolable crying. Examination revealed a swollen toe with a deeply embedded hair tourniquet and no signs of ischemia. Initial manual removal was unsuccessful. But a novel needle-assisted technique was used to hook and cut the embedded hair without incision, achieving complete release.Conclusion: Deeply embedded hair tourniquets can be difficult to detect and manage, often requiring invasive procedures to relieve the constriction and prevent tissue damage. This case highlights a minimally invasive technique as... Continue Reading

Background: Smartwatches are increasingly used as personal health-monitoring tools, but evidence regarding their relationship with mental wellbeing remains limited in Middle Eastern populations. This study investigated the association between smartwatch use, specific smartwatch functions, and mental health symptoms among Saudi adults. Methods: This cross-sectional study included 1,217 Saudi adults aged ≥18 years recruited through social media. An online questionnaire assessed sociodemographic characteristics, smartwatch use, and mental health outcomes using the validated Arabic Depression, Anxiety, and Stress Scale-21 (DASS-21). Multiple linear regression analyses identified predictors of depression, anxiety, and stress scores. Results: Smartwatch use was reported by 48.9% of participants. Depression, anxiety, and stress symptoms above normal levels were reported by 49.1%, 56.1%, and 53.1% of participants, respectively. Among smartwatch functions, only activity tracking was significantly associated with mental health outcomes, showing lower anxiety scores (β = −2.14; 95% CI: −4.54 to −0.26; p = 0.035). Ex-smoking status was the strongest... Continue Reading
