The time distribution of injuries is not random. To assess the potential impact of weather and the phase of the moon on accidents, adjustment for known periodic and nonperiodic factors may be important. We compared the incidence of injuries with quantitative and qualitative weather variables as well as the lunar cycle, after correction for calendar and holiday-related factors.

Increased production of red blood cells (RBCs) should be reflected by increased reticulocyte counts (RC). With the introduction of modern fully automated measurements of RC, the recovery of hemoglobin (Hb) after blood loss might be assessed earlier. We investigated the temporal relation of Hb and RC in trauma patients.

The care for trauma patients has undergone major changes during the last decades. Additionally, many injury prevention measures have been established. The objective of these efforts was to reduce the number of traumatic incidents and to reduce mortality and morbidity in injured patients. The aim of our study was to assess how these measures and improved care have altered trauma mechanisms, occurrence of injuries, treatment, and outcome in the trauma population treated at our trauma center.

Estimating blood loss in trauma patients usually involves the determination of hematocrit (Ht) or hemoglobin (Hb). However, in trauma patients, a poorly substantiated habit exists to determine both Ht and Hb in assessing acute blood loss. This suggests that Ht and Hb provide different information. Moreover, a survey of the literature showed a significant association of the subject trauma with the use of Ht. We investigated whether Ht and Hb differ in trauma patients.
