Comparative Study
Bone mineral density measurements using the Hologic QD2000 in 175 Singaporean women aged 20-80.
The first aim is to obtain a reference database of bone mineral density (BMD) measurements for Singaporean women across different age groups and to compare this with an American database using the same machine. The second is to study the lifestyle factors that may influence bone mass in these women. ⋯ A local reference database is needed for the accurate interpretation of BMD measurements as there is significant variation compared to Caucasian values.

Case Reports
Cardiac tamponade--an unlikely cause of unexplained hypotension in an isolated "minor" blunt chest injury.
Cardiac tamponade after a minor blunt chest trauma is indeed rare. Here, we report on one such case presenting with unexplained hypotension at the Emergency Department. The problems of diagnosis and treatment are discussed. In short, the proper management of this life-threatening condition can only be rendered by a high index of suspicion and close vigilance.
