Hemophagocytic lymphohistiocytosis diagnosed by bone marrow trephine biopsy in living post-COVID-19 patients: case report and mini-review
AbstractHemophagocytic lymphohistiocytosis (HLH) constitutes a life-threatening inflammatory syndrome. Postmortem histological findings of bone marrow (BM) from COVID-19 patients showed histiocytosis and hemophagocytosis and supported the hypothesis that secondary HLH (sHLH) may be triggered by SARS-CoV-2 infection. However, there are a limited number of sHLH cases in which trephine has been performed in living post-COVID-19 patients. Here we present a recent case and a mini-review of sHLH diagnosed by trephine biopsy in living patients after COVID-19. An 81-year-old man with a past medical history of hypertension, diabete...

Optical Coherence Tomography Evaluation of Carotid Artery Stenosis and Stenting in Patients With Previous Cervical Radiotherapy
CONCLUSION: The morphological features of RICS were heterogeneous, including heterogeneous signal-rich tissue, dissection, and advanced atherosclerosis. Stenting was successful in all 5 patients with severe RICS. One patient, with high rates of tissue protrusion and stent strut malapposition immediately after stenting, received in-stent neointimal hyperplasia at a 6-month follow-up.PMID:35573285 | PMC:PMC9095735 | DOI:10.3389/fnins.2022.861511

Peg-leg arterioles: an adaptation to chronic retinal hypoperfusion
Conclusion: Chronic severe retinal hypoperfusion due to profound carotid occlusive disease can lead to adaptive remodeling of the retinal vasculature in a pattern that closely resembles the iconic image of a pirate's peg leg.

Oculoplastic Surgeries in Patients Older than 90 Years of Age
CONCLUSION: In our experience, oculoplastic surgeries among the elderly population are safe without significant complications and can usually be performed under local anesthesia. Advanced age should not prevent surgery, especially if the procedure may improve vision and quality of life.PMID:35377245 | DOI:10.1177/11206721221086153

Vertebral artery stenosis predicts cerebrovascular diseases following radiotherapy for nasopharyngeal carcinoma
CONCLUSION: Our study found that NPC patients with vertebral artery stenosis, atrial fibrillation, or hypertension carry a higher risk for ischemic stroke or TIA. Regular assessment of vertebral artery after radiotherapy was suggested.PMID:35357575 | DOI:10.1007/s00520-022-07011-8

Sphingosine 1-phosphate and its regulatory role in vascular endothelial cells
We presently review the levels of S1P in those vascular and vascular-related diseases. Plasma S1P levels were reduced in various inflammation-related diseases such as atherosclerosis and sepsis, but were increased in other diseases including type 2 diabetes, neurodegeneration, cerebrovascular damages such as acute ischemic stroke, Alzheimer's disease, vascular dementia, angina, heart failure, idiopathic pulmonary fibrosis, community-acquired pneumonia, and hepatocellular carcinoma. Then, we highlighted the molecular mechanism by which S1P regulated EC biology including vascular development and angiogenesis, inflammation, p...
