BACKGROUND The bacterial organism Capnocytophaga canimorsus is an oral commensal of cats and dogs and can cause life-threatening infections like mycotic aneurysm, meningitis, and sepsis. Mycotic aneurysms occur when microbial infections cause arterial wall degeneration. Difficulty in diagnosing Capnocytophaga canimorsus infection can occur due to the bacteria's fastidious nature and laboratory testing limitations, contributing to the infection's high morbidity and mortality.

Methods: We performed a retrospective review of consecutive patients presenting with retinal ischemia who subsequently underwent carotid intervention from January 2018 to December 2022. Patients were classified into three groups (group I: amaurosis fugax/vascular transient monocular vision loss, group II: ocular ischemic syndrome [OIS], and group III: central/branch retinal artery occlusion).

Acute thrombosis of the aorta is an uncommon, but potentially devastating, vascular emergency. The absence of pathognomonic signs or symptoms makes the diagnosis challenging and, often, time consuming. No optimal treatment has been established, with greater challenge present when the thrombus involves the mesenteric-renal vessels.

- Rural community practices in the U.S. are increasingly involved in medical education and are encouraged to give academic appointments to non-academic physicians.
- A formal education committee was established in a rural regional practice to facilitate the adoption of academic ranks through various administrative changes over three years.
- As a result, the percentage of physicians with academic rank rose significantly from 41.1% to 92.8%, demonstrating that process changes can effectively enhance academic appointments, improve educational programs, and boost physician satisfaction and retention.
Article Synopsis
- Acoustic shadowing can interfere with Doppler assessments in prosthetic heart valves (PHVs), which might hide issues like mitral regurgitation (MR).
- Spectral Doppler is a key technique for identifying prosthetic mitral regurgitation.
- Transesophageal echocardiography (TEE) can enhance the evaluation when transthoracic echocardiography (TTE) is limited, helping to reduce interference from acoustic shadowing and reverberations.
