The purpose of this study was to study the association of anterior cruciate ligament (ACL) injury with meniscal, collateral ligament, and bone injuries using magnetic resonance imaging (MRI) for clinical correlation during ACL repair. Methods This was a retrospective cohort study conducted on 136 patients diagnosed with ACL injury by MRI at King Abdulaziz University Hospital (KAUH) between September 2010 and September 2018. Results The medial meniscus was injured in approximately half (49.3%) of patients, while the lateral meniscus was injured in 16.2%. Regarding collateral ligament injuries, the medial collateral ligament was injured in six patients (4.4%), the lateral collateral ligament in four patients (2.9%), and both collateral ligaments in three patients (2.2%). There was a significant relationship between the age group and the side of ACL injury (P<0.05) but not between the age group and the presence of an associated injury. Conclusion There was no significant relationship between ACL injury and menisci, collateral ligament, or bone injury.
Background: Low back pain (LBP) is considered to affect both young and elderly adults. Med students appear to provide time-consuming curricula, likely perpetuating sedentary habits and a significant burden of LBP among med students. The primary aim of the present study was to evaluate the prevalence of LBP and to see if there is any association between LBP and sedentary lifestyle or (to identify the associated factors) among medical students in King Abdulaziz University. Methodology: A quantitative cross-sectional study included 380 out of 2000 medical students from all years using a self-administered questionnaire in English distributed to a targeted sample adapted from previously published research by AlShayhan et al. Results: 52.4% were females and 47.6% males. 26.3% of participants were 20 years or less, 37.3% were 21-22 years. 19.3% were smokers. 34.6% practice exercises currently. The number of hours using computers or tablets was reported as 2-4 hours in 15.9%, 4-6 hours in 22.4%, 6-8 hours in 18.1%, and 8-10 hours in 12.7%. 7.9% reported a history of surgery or trauma to the back, 44.2% reported a history of back pain in family members and treated by a doctor, 49% had a history of low back trouble since joined the college (ache, pain, discomfort), 54.7% had a history of low back trouble once in life (ache, pain, discomfort), 3.7% reported a history of hospitalization because of low back pain and 9.3% reported skipping a day because of low back pain. Conclusion: Lower back pain is common among med school students in King Abdulaziz University, Saudi Arabia. It is significantly associated with age and the number of hours using computers or tablets. University students should be advised to avoid risk factors as much as possible.
IntroductionFollowing the World Health Organization (WHO) declaration of coronavirus disease 2019 (COVID-19) as a pandemic, Saudi Arabia took unpreceded precautions to prevent and control the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. It is one of the first countries in the world to grant the authorization to use the Pfizer-BioNTech vaccine. This study aimed to assess the effect of one dose of COVID-19 vaccines (Pfizer-BioNTech, Manhattan, New York City, and Oxford-AstraZeneca, Cambridge, United Kingdom) among the Saudi population regarding symptom severity, hospital admission rate, and death. MethodsAn observational retrospective cohort study was conducted using data from COVID-19 surveillance records at King Abdulaziz Medical City (KAMC), Saudi Arabia, from January to May 2021. All confirmed COVID-19 patients who had positive tests by reverse transcription polymerase chain reaction (RT-PCR) assay of a nasopharyngeal swab were included in the study. Patients diagnosed outside KAMC and cases below 18 years old were excluded from the study. The research was approved by King Abdullah International Medical Research Center (NRJ21J/303/12). Multivariable logistic regression was conducted to estimate the odds of hospitalization among vaccinated and unvaccinated patients. ResultsA total of 1058 cases were included in the analysis. Two hundred sixty-five (265; 25%) patients were vaccinated with one dose of either Pfizer-BioNTech or Oxford Astra-Zeneca, and 793 (75%) were unvaccinated. The median age was 34 (IQR 25-51), primarily Saudi (94.6%) and male (59.5%). The odds of being vaccinated (CI: 1.284-2.882, P 0.002) were 1.924 times greater for males than females. Young patients below 40 had 1.997 times higher odds (CI: 1.238-3.222, P 0.004) of being vaccinated than patients above 60. The hospital admission rate was low among both groups (12.9%); however, it was significantly lower among the vaccinated group (2.3%) as compared to the unvaccinated (16.5%). The results showed significant differences in symptom severity among the groups. For vaccinated, only one patient (0.4%) died, one patient was admitted to the ICU, and one patient (0.4%) was admitted to the hospital isolation ward. On the contrary, among the unvaccinated group, 19 patients (2.4%) died, 17 patients (2.1%) were admitted to the ICU, and 114 patients (14.4%) were admitted to the hospital isolation ward. ConclusionThis study demonstrates that one dose of COVID-19 vaccines, either Pfizer-BioNTech or Oxford-AstraZeneca, reduced the probability of death by 2% and hospital admission by 15% before the spread of the Delta variant (B.1.617). For generalizable results, nationwide studies using national surveillance data are recommended to assess multiple doses efficacy on different variants of the SARS-CoV-2 infection.
