“…A similar finding was made by Hamilton et al (1965). Gardiner et al (1966) and Hall et al (1972) found a peak incidence of bleeding in January, with a summer fall-off, but the present findings agree with the conclusions of Schiller et al (1970) in that this tendency, though present, is slight.…”

Perforated gastroduodenal ulcer was studied in 1483 patients in the Bergen area during the years 1935-90 to discover time trends in age and sex, disease characteristics, treatment, and outcome. The male:female ratio feli from 10:1 to 1*5:1, median age increased from 41 to 62 years. Most perforations were found in the duodenum in 1935-64, and in the pyloric and praepyloric area in . There was a 10% occurrence of gastric ulcers throughout the study period. Ulcer site was related to age (more gastric and less duodenal perforations with increasing age) and sex (more pyloric and less duodenal ulcers among women). There were twice as many perforations in the evening compared with the early morning. The diurnal variation was more pronounced for duodenal and pyloric than for gastric and praepyloric perforations. Circadian and seasonal variation of ulcer perforation did not change during the 56 years studied. Treatment delay increased from median five hours to median nine hours.

“…Conflicting results have been reported regarding the seasonal fluctuations of peptic ulcers and bleeding from peptic ulcers, and many of them indicated seasonal fluctuations 1–12,19–24 . Boles and Westerman indicated the correlations between hemorrhages from DU, temperature and temperature change 1 .…”
