ABSTRACT
A cross-sectional study was conducted in order to construct a new reference chart for Thai fetal femur length (FL). A total of 621 normal pregnant women between 12-41 weeks of gestation and their fetuses were enrolled. Measurements were made once at a randomly assigned gestational age specifically for the purpose of this study only. Femur length data were available in 608 measurements due to unfavorable fetal position in some cases. Linear regression technique was used to model separately the mean and standard deviation as functions of gestational age. Reference centiles were constructed from a combination of both models, assuming the data were normally distributed. A new reference centiles chart for FL is presented and compared with previously published data. While our derived centiles were clearly lower than those from Western studies, they were found comparable with those from a Thai study. This demonstrated the important effect of racial differences between populations on fetal biometries and elucidates the need to develop fetal biometries charts specifically for each region.

Cesarean hysterectomy remains a necessary procedure for life saving during abdominal delivery. The procedure itself is usually associated with considerable perioperative morbidity, especially when performed under emergency conditions. Obstetricians should identify patients at risk and anticipate the procedure and its complications. Knowledge of this operation and skill at its performance can be very helpful in reducing perioperative maternal and perinatal morbidity.

This study aimed to establish the mean age of menopausal in Thai women. One thousand women, aged 40-69 years, were interviewed with a structured questionnaire at the Out-Patient Department, ceased to menstruate. The mean age with standard deviation among this group of women was 51.24 + 3.79 years by Probit analysis. However, among these 596 women 514 could recall their actual age at menopause. This mean age with standard deviation was 48.68 + 2.31 years. Thus, there is a statistically significant difference between the two values (P<0.01).
