ABSTRACT
OBJECTIVES: Calls to carry efforts to increase awareness about venous thromboembolism (VTE) as a preventable major healthcare problem with serious consequences has been upraised. This study was planned to get an overview of the awareness, knowledge, and attitude toward VTE among Aseer population, Saudi Arabia and the need for an education plan. MATERIALS AND METHODS: Questionnaire composed of 35 questions based cross-sectional study was conducted online via Google documents to public in Aseer that included both genders aged more than 18 years who agreed to be involved in the study, to assess knowledge and attitude toward VTE. The collected data were presented as numbers, percentages, and were analyzed using Statistical Package for Social Sciences version 24. RESULTS: The results of the data showed that awareness knowledge and attitude toward VTE were lacking and unsatisfactory. CONCLUSION: Diligence to spread knowledge and awareness of VTE among public in Aseer is required. Further surveys involving other populations are warranted.
ABSTRACT
BACKGROUND: This study aims to describe the radiological findings in chest radiographs (CXRs) of patients with coronavirus disease (COVID-19) and the Middle East respiratory syndrome (MERS) and to compare the radiological patterns of the two diseases. METHODS: A retrospective cohort study was conducted in a tertiary care hospital in the Southern region of Saudi Arabia. The CXRs were evaluated for the presence and distribution of ground-glass opacities (GGO), consolidation, pleural effusions, pneumothorax, cavitation, and nodules. RESULTS: A total of 120 CXRs from 15 MERS and six COVID-19 patients were assessed. In the first available CXR, GGO was present in 11 (73%) of the MERS patients (18% located in the middle zones and 67% located peripherally) and in 100% of COVID-19 patients (peripheral and middle zone involvement in all patients). In the first available CXRs, consolidation was present in 10 MERS patients (67%) and in all six COVID-19 patients, while it was present in all patients of both groups when all the available CXRs were considered. Confluent consolidation was present in 47% of the MERS patients and 50% of COVID-19 patients. All the fatal cases had confluent consolidation and radiological signs of acute respiratory distress syndrome (ARDS). Pneumothorax was present in 13% of patients, with 100% mortality, and pleural effusion was present in 47% of patients, with 57% mortality. Lung nodules were present in one patient of each group. CONCLUSION: COVID-19 patients showed earlier development of GGO and consolidation with greater involvement of the middle and peripheral lung zones. Confluent consolidation and ARDSlike radiological findings were associated with high mortality. Pneumothorax and pleural effusions were more frequent in MERS patients, with high associated mortality.

ABSTRACT: Pulmonary embolism (PE) is a common medical problem. Its diagnostic criteria must be reviewed to determine the need for confirmatory testing. Computed tomography pulmonary angiography (CTPA) is the current standard of care, which provides accurate diagnosis with rapid turnaround. This study aimed to estimate the diagnostic yield of CTPA in clinically suspected PE patients in a tertiary care hospital in Saudi Arabia.Radiology records of all patients with clinically suspected PE who underwent CTPA between January 1, 2012 and September 30, 2018 were reviewed retrospectively. A radiologist with 10 years of professional experience interpreted and reported all cases. The Wells score with 2 tiers (likely and unlikely) was used to raise the clinical suspicion of PE.Positive results for PE were reported in 177 out of 534 clinically suspected cases (33%). Among the positive PE cases, 143 were acute (81%) and 34 (19%) were chronic. Bilateral, right-sided, and left-sided PE were found in 115 (65%), 37 (21%), and 25 (14%) cases, respectively. Involvement of the segmental branches, subsegmental branches, and the pulmonary trunk were noted in 152 (86%), 70 (40%), and 9 cases (5%), respectively. Saddle PE was found in (4%) of the cases. The lower lobe branches (right 55%, left 53%) and the upper lobe branches (right 47%, left 41%) were the most common sites of involvement.CTPA had a higher positive detection rate for PE among clinically suspected cases than its published diagnostic yield. Adequate clinical evaluation when selecting patients for CTPA is emphasized to minimize unjustified exposure of the patients to radiation and intravenous contrast administration. It is crucial for radiologists to provide detailed reports commenting on all relevant findings, including pertinent negatives. A template for reporting radiological findings for CTPA can be recommended for this purpose.
