Holy Shroud Exhibition 2010: health services during a 40-day mass-gathering event.

INTRODUCTION: Mass-gathering events require varying types and amounts of medical resources to deal with patient presentations as well as careful planning for environmental health management. The Holy Shroud Exhibition was hosted in Torino, Italy, between April and May 2010. The venue was a unique mass-gathering event which lasted several weeks. It was held in a limited area in the center of the city and it was attended by a large and heterogeneous population. A dedicated Health Care Service was created for the event. METHODS: This study is a retrospective analysis of clinical presentations of patients who were managed by the Medical Services during the event. The main study outcomes included Patient Presentation Rate (PPR), type of injuries and illnesses, and the Transport to Hospital Rate (TTHR). RESULTS: The PPR and TTHR were both low (0.27 and 0.039 respectively). The majority of patients presented with low severity codes and no sudden cardiac death (SCD) or cardiac arrest occurred. Cardiac and trauma emergencies were most frequent categories of presentation. A number of pediatric patients (19.37%) were treated by the event Medical Service. Approximately two million persons participated in the 40-day event. CONCLUSION: The experience for this 40-day event supported having an on-site, organized, dedicated Medical Service that decreased overcrowding of the local Emergency Medical System and hospitals. It is recommended that, for such events, there be recruitment of emergency physicians with experience in mass-gathering events, recruitment of pediatricians, and training for professionals during the planning process.

Cervical spine segmental vertebral motion in healthy volunteers feigning restriction of neck flexion and extension.

The purpose of this study was to obtain comparative data concerning the percentage contribution of segmental cervical vertebral motion to the cervical range of motion (ROM) in healthy volunteers under two conditions: (1) normal, voluntary neck flexion and extension and (2) feigned restriction of neck flexion and extension. Each healthy subject's angular motion over forward cervical flexion and extension was measured first by X-ray analysis during normal, voluntary motion. Then the subjects were asked to pretend that they had a 50% restricted neck range due to pain or stiffness and thus to move in both flexion and extension only as far as about 50% of their normal range. A total of 26 healthy subjects (ten males and sixteen females, age 28.7+/-7.7 years) participated. The total angular motion from C2 to C7 was normal in the unrestricted condition and was significantly reduced in the feigned restriction condition (p<0.001). The percentage contribution of each of the functional units C2-C3 to C6-C7 to this rotation was different between the normal unrestricted and the feigned restricted conditions. In the feigned restricted neck flexion and extension, a shift occurred in the pattern of how each segment contributes to the total angular range. A greater percentage contribution was made by C2-C3 and C3-C4 than under normal conditions (P<0.01), and the percentage contribution to total rotation made by C6-C7 became much less under the feigned restricted movements than under normal, unrestricted neck range (p<0.001). Thus, simulated or feigned restricted neck ROM affects the percentage contribution of the functional units C2-C3 to C6-C7 by showing a higher percentage contribution of the upper cervical segments and less contribution to the angular rotation by the lowest cervical segment. Feigners of restricted neck range thus produce a pattern different from nonfeigning subjects.
