Observational Study
Effect of combination of prophylactic or therapeutic anticoagulation with aspirin on the outcomes of hospitalized COVID-19 patients: An observational retrospective study.
Regimens for managing thromboembolic complications of COVID-19 are still not very well established. The present study compares the clinical characteristics and outcomes of patients hospitalized with COVID-19 receiving different anticoagulation regimens with and without aspirin. This is a retrospective observational study of 491 patients hospitalized for COVID-19 from August 2020 to April 2021. ⋯ Patients with severe COVID-19 infections were more likely to receive higher, therapeutic, anticoagulation doses. Aspirin was given to patients with preexisting comorbidities, but it had no statistically significant impact on the outcomes of the different groups. Groups receiving prophylactic anticoagulation had the best survival outcomes.

Case Reports
Tocilizumab-induced mucosal injury in the terminal ileum mimicking intestinal Behçet's disease: A case report.
Tocilizumab, a humanized anti-interleukin-6 (IL-6) receptor monoclonal antibody, is used for the treatment of adult-onset Still disease (AOSD). Despite its efficacy in many clinical situations, concerns have been raised regarding intestinal mucosal injury in patients receiving tocilizumab. ⋯ Tocilizumab can cause deep ulcerative lesions in the terminal ileum, which may resemble intestinal Behçet's disease. It is important to continuously monitor abdominal symptoms during tocilizumab therapy and aggressively perform colonoscopy when hematochezia or abdominal pain is observed.

Visceral obesity is an important factor that increases the risk of complications after colorectal cancer surgery. As calculating visceral fat is difficult and time-consuming, more practical fat measurements that are not time-consuming have been introduced. This study aimed to investigate the effects of perirenal fat thickness on postoperative complications and prognosis in patients undergoing surgery for colorectal cancer. ⋯ Multivariate analysis revealed that increased perirenal fat thickness is an independent risk factor for postoperative complications. We believe that perirenal fat thickness measurement, as an indicator of visceral fat volume, can be used to identify patients at high risk of developing complications after colorectal cancer surgery. This may change the disease management and affect the patient information process.

Ossification of the pterygoalar ligament, which lies inferolateral to the exocranial opening of the foramen ovale, is traditionally considered to be a bony bar that could obstruct percutaneous needle access to the foramen ovale using the Hartel approach. We herein present two case reports of successfully penetrating the foramen ovale by a needle across the pterygoalar bar. Lack of knowledge of this type of presentation might lead to a change in the surgical approach. ⋯ During percutaneous radiofrequency thermocoagulation for the treatment of trigeminal neuralgia, the Hartel approach can still be used when the foramen ovale is blocked by a pterygoalar bar. To our knowledge, this is the first report of such a treatment. Moreover, we herein provide specific technical recommendations to assist surgeons who may encounter such cases in the future.

To evaluate the effects of aspirin in the primary prevention, we evaluated disability grades and mortality after ischemic/hemorrhagic stroke and myocardial infarction (MI). A retrospective nation-wide propensity score-matched cohort study was performed using the Korean National Health Information Database. From 3,060,639 subjects who were older than 55 and performed national health examinations in 2004 and 2005, we selected the aspirin group (N = 8770) was composed of patients who had received aspirin prior to cardiovascular events. ⋯ The old age was a strong risk factor for 90-day mortality in hemorrhagic stroke (50s: reference; 60s: HR 2.21, 95% CI 1.50-3.25; 70s: HR 3.63, 95% CI 2.48-5.30; 80s: HR 6.69, 95% CI 4.54-9.65; >90s: HR 11.28, 95% CI 6.46-19.70). Pre-aspirin use in cardiovascular events has detrimental effects on severe neurological disability in hemorrhagic stroke and short-/long-term mortality in 3 cardiovascular events. The use of aspirin for the primary prevention especially in the elderly should be very cautious because the old age is a strong risk factor for 90-day mortality after hemorrhagic stroke.
