This paper is an analysis of "the demographic and socio-professional characteristics of the Italian community settled in Australia after World War II and its spatial distribution." The authors note that the first generation of migrants, no longer replenished with new arrivals since the 1960s, is aging rapidly, is concentrated in urban areas, and is no longer engaged in independent work in rural areas. An analysis of second-generation Italian immigrants is also presented, with reference to questions of assimilation and intermarriage. Data are primarily from a survey undertaken in 1982.

The angiographic visualization of the pancreatic arteries, their numerical variations, origins, course and anastomoses, as well as their mean diameter by age-group (20-40, 41-60, greater than 60 years) have been quantitatively investigated by selective celiac angiography in 72 patients without pancreatic disease. Visualization of the various arteries was achieved in a high percentage of cases except for the inferior pancreaticoduodenal arches, due to undervaluation of this vessel by celiac angiography. Confirmation of the great variability of the origin and anastomoses of the dorsal and transverse pancreatic arteries was obtained and possible embryologic reasons and clinical implications of this fact are discussed. Furthermore, a high percentage of multiple (quadruple or more) pancreatica magna and caudae pancreatis arteries has been observed and a functional role of this peculiar arrangement is suggested. Finally, no statistically significant differences were found in the diameter of any artery due to increasing age, probably reflecting maintained neural perivascular control of the pancreatic vessels in the elderly. Satisfactory sensitivity of the angiographic method has been found with respect to the evaluation of visualization and anastomoses of the pancreatic arteries in vivo.
