Article Synopsis
- Giant cell arteritis (GCA) is a common condition in individuals over 50 that can lead to serious issues like vision loss if not diagnosed quickly.
- This study assesses the effectiveness of using color Doppler ultrasound as the first step for diagnosing GCA, followed by temporal artery biopsy for those who test negative on the ultrasound.
- The findings showed that ultrasound confirmed GCA in 44% of cases, compared to 17% for biopsy and 21% for other methods, but the study had limitations like a small sample size and no objective gold-standard for comparison.
Article Synopsis
- - Merkel cell carcinoma (MCC) is often linked to the Merkel cell polyomavirus (MCPyV), particularly when the virus integrates into the host's DNA and leads to mutations in the Large T antigen (LT), which is essential for the virus's cancer-causing properties.
- - In recent cases involving MCC combined with skin tumors called trichoblastoma and poroma, researchers found evidence of MCC developing from epithelial cells and identified both mutated and wild-type LT sequences.
- - The findings indicate that some MCC cases may contain intact MCPyV genomes and express certain viral proteins, suggesting a more complex interaction between the virus and cancer than previously understood.
Introduction: Venous thrombosis has not previously been reported as a complication of lymphocytic gastritis.
Case: A 47-year-old patient was admitted for anasarca related to varioliform gastritis. The densitometric examination showed two partial thromboses, at the confluence of the splenic and mesenteric veins and in the postrenal vena cava.
