Penetrating Atherosclerotic Ulcers of the Abdominal Aorta: A Case Report and Review of the Literature

Penetrating atherosclerotic ulcers (PAUs) of the aorta are defined as atherosclerotic lesions with aortic intima and media ulceration, which may lead to a complete rupture of the adventitial wall. The present article aimed to report an unusual case of a surgically treated patient with abdominal aorta PAU with an illustration of the key features and to review and analyze the existing literature data. PAUs typically develop in elderly and hypertensive patients and in patients with advanced atherosclerosis. Although originally described for the descending thoracic aorta, a similar clinicopathological entity also occurs in the abdominal aorta. Patients with symptoms of a PAU should be treated immediately if they are fit for surgery. Exceptive observation by imaging modalities is necessary in patients with asymptomatic small (<2 cm) PAU, with or without focal dissection.

Polymorphisms of the BARX1 and ADAMTS17 Locus Genes in Individuals With Gastroesophageal Reflux Disease

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD) represents a common condition having a substantial impact on the patients' quality of life, as well as the health system. According to many studies, the BARX1 and ADAMTS17 genes have been suggested as genetic risk loci for the development of GERD and its complications. The purpose of this study is to investigate the potential association between GERD and BARX1 and ADAMTS17 polymorphisms. METHODS: The present is a prospective cohort study of 160 GERD patients and 180 healthy control subjects of Greek origin, examined for BARX1 and ADAMTS17 polymorphisms (rs11789015 and rs4965272) and a potential correlation to GERD. RESULTS: The rs11789015 AG and GG genotypes were found to be significantly associated with GERD (P = 0.032; OR, 1.65; 95% CI, 1.06–2.57 and P = 0.033; OR, 3.00; 95% CI, 1.15–7.82, respectively), as well as the G allele (P = 0.007; OR, 1.60; 95% CI, 1.14–2.24). Concerning the rs4965272, only the GG genotype was significantly associated with GERD (P = 0.035; OR, 3.42; 95% CI, 1.06–11.05). CONCLUSIONS: This is a study investigating the potential correlation between BARX1 and ADAMTS17 polymorphisms and the development of GERD, showing a considerable association between both polymorphisms and the disease. This finding suggests that esophageal differentiation or altered regulation on microfibrils in the cell environment could be implicated as possible mechanisms in the pathogenesis of GERD.
