Trans-arterial omental flap protection for infected femoral artery aneurysm in a patient with Parkes-Weber syndrome.

We report a case of a 75-year-old man diagnosed with Parkes-Weber syndrome with an infected common femoral artery aneurysm secondary to chronic venous ulcers and groin infection. Given the symptomatic and rapid enlargement of the aneurysm, emergency aneurysmectomy and crossover femoro-femoral bypass were performed with an omental flap routed intraluminally through the aneurysm of the ipsilateral external iliac artery. The transarterial route enabled the short-cutting of the omental flap and the potential prevention of infection in the adjacent external iliac artery.

Vaginal assisted NOTES hysterectomy for large uterus using the da Vinci SP.

Objective: Recent advancements of minimally invasive gynecologic surgery have led to the development of transvaginal natural orifice translumenal endoscopic surgery (vNOTES) [1,2]. Robot-assisted vNOTES has also been explored as a method providing accurate and fine surgical procedures with improved ergonomics, visualization, wristed instruments, elimination of the hand tremor [3,4]. The objective of this video is to demonstrate the technical and anatomical highlights of a vaginal assisted NOTES hysterectomy (VANH) using the da Vinci SP (SP).

Magnitude and dynamics of the T-cell response to SARS-CoV-2 infection at both individual and population levels.

Introduction: T cells are involved in the early identification and clearance of viral infections and also support the development of antibodies by B cells. This central role for T cells makes them a desirable target for assessing the immune response to SARS-CoV-2 infection.

Methods: Here, we combined two high-throughput immune profiling methods to create a quantitative picture of the T-cell response to SARS-CoV-2.

Achievement of duodenal ulcer remission by vedolizumab in children with eosinophilic gastroenteritis.

Eosinophilic gastrointestinal disorders (EGIDs) are treated with corticosteroids and food allergen elimination. However, treatment for refractory cases is not standardized. We demonstrate the efficacy of vedolizumab, an anti-α4β7 integrin agent, in 2 children with duodenal ulcers developed by non-eosinophilic esophagitis EGIDs.
