Some schizophrenic patients have decreased pain perception while others have decreased pain expression. These factors frequently lead to difficulties in the diagnosis of acute intra-abdominal surgical emergencies. Increasingly large numbers of schizophrenic patients are being cared for in the community. It is therefore imperative that surgeons be acutely aware of the diagnostic dilemmas presented by this group of patients so that misdiagnosis is avoided and appropriate surgical therapy is instituted in a timely manner.
The apparent incidence of abdominal aortic aneurysms among Rochester, Minnesota residents increased seven-fold between 1951 and 1980, while the incidence of thoracic aortic aneurysms declined somewhat. Rates for abdominal aneurysms rose with age and were greater among men. The overall incidence in 1971-1980 was 36.5 per 100,000 person-years. While all clinical classes of abdominal aortic aneurysms became more frequent, the greatest rise in incidence was for small, asymptomatic, and uncomplicated aneurysms which suggested an important role for more complete case ascertainment in recent years. The secular trend in abdominal aortic aneurysm incidence seems to be different from that observed for stroke or for coronary heart disease in the same community.

Seasonal variations were observed in reticulocyte numbers and relative organ masses of the spleen, thymus, and kidneys in the northern red-backed mouse, Clethrionomys rutilus, in the vicinity of College, Alaska, during 1963 and 1964. There was a significant correlation between reticulocyte level and relative spleen weight and between relative spleen and thymus weights. There was no correlation between reticulocyte number and relative weight of the paired kidneys, but there were corresponding peaks in these parameters which appeared to be approximately 1 month out of phase with increase in kidney weights preceding increases in reticulocyte numbers. The probable significance of these variations is discussed in terms of adjustments of the red-backed mouse to seasonal cold exposure.
