Is the frequency of pre-seasonal manifestation in patients with Japanese cedar pollinosis so high?
Many factors such as method of pollen survey, personal nasal hyper-reactivity and irritation by cold air, or with pollens other than Japanese cedar may cause the pre-seasonal pollinosis symptom. High frequencies of pre-seasonal onset in previous reports may be over-estimated due to inaccurate diagnosis of Japanese cedar pollinosis.
Even after adjustment for differences in patient characteristics, there are differences between the hospital treatment cultures for patients with AMI that persists over time. Concerning everywhere-available treatment options, the treatment activity is independent of the size of the center. A more active treatment tradition is associated with a lower short- and long-term mortality in AMI patients.
