To better understand the impact of ethnic identity, it is important to examine people's social construction, or definition, of that identity. In this study, the social construction of ethnic identity of predominantly low-acculturated, first-and second-generation U.S. Mexicans and Mexican Americans was examined by asking focus group participants to talk about what it meant to them to be members of their ethnic groups. These open-ended responses then were coded along Phinney's aspects of ethnicity. Several interesting patterns emerged, some of which have not been emphasized in previous literature, such as conflict with African Americans and Chicanas/Chicanos. Discussion centers on the value of listening to people's social constructions of their ethnic identity to better understand their social realities. An ethnic group is the reference group with whom people share a common history, physical features, and culture, and it is through interaction with reference group members that people identify themselves as members of a given group and incorporate an ethnic identity (Phinney, 1996). People's personal realities or social constructions of their ethnic groups can have implications

The celiac axis compression syndrome (CACS) due to median arcuate ligament (MAL) was first described by Harjola in 1963; originating postpandrial abdominal pain, weight loss, epigastric bruit and celiac axis stenosis > 75% in angiographic studies. This clinical condition has been the origin of controversies about its pathogenesis, diagnosis and its long term clinical results. Advances in diagnostic imaging as 64 multidetector-row CT (MDCT), 3-D reconstruction, magnetic resonance (MR) and color duplex ultrasonography, provide better understanding of the syndrome and allow to identify the best candidates for surgical division of MAL fibers. Since the introduction of laparoscopic approach, and also endovascular procedures, in 2000, a new perspective has established in this challenging syndrome. With the occasion of our own experience, a critical review of the syndrome is presented.
