Abstract
BACKGROUND There are only few studies concerning the usage of antibiotics in preventing endometritis after uterine curettage for spontaneous first trimester incomplete abortion and no conclusion can be demonstrated OBJECTIVE To investigate the effectiveness of prophylactic cefoxitin in preventing endometritis after uterine curettage for spontaneous first trimester incomplete abortion. MATERIAL AND METHOD Eighty-four women with spontaneous first trimester incomplete abortion were randomly allocated into two groups using a computer-generated random number list and the allocation concealment was maintained using a sealed opaque envelope. The patients in the study group were given 1 g of cefoxitin while the patients in the control group were given 0.1 ml of vitamin B complex intravenously 20 minutes prior to curettage. Uterine curettage was performed after intravenous sedation and analgesic drugs were administered. The patients were evaluated on the first, third and seventh day after uterine curettage. RESULTS Seventy-nine cases had completed the study protocol. There were no statistically significant differences in demographic data and details of uterine curettage between both groups. Two cases of endometritis were found in the control group but none in the study group. However the difference did not reach the statistical significance (p = 0.241). CONCLUSION Prophylactic cefoxitin is not effective in preventing endometritis after uterine curettage for spontaneous first trimester incomplete abortion.

Abstract
OBJECTIVE To identify the correlation between gestational weight gain in pregnant women with normal pre-pregnancy body mass index (BMI) and fetal weight gain. MATERIAL AND METHOD Uncomplicated normal pre-pregnancy BMI Thai singleton pregnant women with less than 16 weeks' gestation participated in this study between June 2008 and September 2009. Serial measurements of maternal and fetal weight using ultrasound examination were recorded every four weeks from 16 to 36 weeks' gestation. RESULTS Two hundred seventy four uncomplicated pregnant women were included in this study of which 166 met inclusion criteria during a period of the study. There was a significant correlation between gestational weight gain and both estimated fetal weight gain and actual infant birth weight (p < 0.05). Using the multiple regression analysis, gestational weight gain between 16 to 28 weeks' gestation, multiparity, and male infants were independent factors and were significantly correlated with both fetal weight gain and actual infant birth weight (p < 0.05). CONCLUSION For pregnant women with normal pre-pregnancy BM, gestational weight gain can predict intrauterine fetal weight as well as infant birth weight.

Abstract
Background Human amniotic fluid stem (hAFS) cells have become an attractive stem cell source for medical therapy due to both their ability to propagate as stem cells and the lack of ethical debate that comes with the use of embryonic stem cells. Although techniques to derive stem cells from amniotic fluid are available, the techniques have limitations for clinical uses, including a requirement of long periods of time for stem cell production, population heterogeneity and xeno-contamination from using animal antibody-coated magnetic beads. Herein we describe a novel isolation method that fits for hAFS derivation for cell-based therapy. Methods and Results With our method, single hAFS cells generate colonies in a primary culture of amniotic fluid cells. Individual hAFS colonies are then expanded by subculturing in order to make a clonal hAFS cell line. This method allows derivation of a substantial amount of a pure stem cell population within a short period of time. Indeed, 108 cells from a clonal hAFS line can be derived in two weeks using our method, while previous techniques require two months. The resultant hAFS cells show a 2-5 times greater proliferative ability than with previous techniques and a population doubling time of 0.8 days. The hAFS cells exhibit typical hAFS cell characteristics including the ability to differentiate into adipogenic-, osteogenic- and neurogenic lineages, expression of specific stem cell markers including Oct4, SSEA4, CD29, CD44, CD73, CD90, CD105 and CD133, and maintenance of a normal karyotype over long culture periods. Conclusions We have created a novel hAFS cell derivation method that can produce a vast amount of high quality stem cells within a short period of time. Our technique makes possibility for providing autogenic fetal stem cells and allogeneic cells for future cell-based therapy.

Abstract
OBJECTIVE Maternal pre-pregnancy weight is a risk of developing preeclampsia. Whether it is also associated with the disease severity is still elusive. This retrospective cohort was to determine the association between body mass index (BMI) at term and severity of preeclampsia. MATERIAL AND METHOD BMIs on the delivery date of 229 patients were analyzed with various indicators of the disease severity. The corrected BMI (cBMI), calculated by an exclusion of feto-placental unit, was additionally analyzed. RESULTS Neither maternal BMI nor cBMI correlated with the disease severity (p = 0.15 and 0.36). Patients who did and did not require MgSO4 do not have different BMI or cBMI (p = 0.12 and 0.23). Neonatal weight from severe disease arm does not differ from those with mild disease (p = 0.51). Counter-intuitively the correlations between birth weight and maternal BMI were stronger in the severe compared to the mild group (p = 0.0 and 0. 03). CONCLUSION Neither BMI nor cBMI at the time of delivery predict the severity of preeclampsia or the need for seizure prophylaxis. Birth weight of the baby born from preeclamptic mother might be affected by multiple factors.

Abstract
BACKGROUND Perineal pain after episiotomy is a common problem following vaginal birth. The pain affects either physical or mental function negatively. There are many methods in perineal pain relief such as local ice pack and a bath, ultrasound, oral anesthesia, and intravenous anesthesia. Analgesic rectal suppository is one of various methods in pain relief especially in drowsy patients, or when oral preparation causes gastric discomfort, nausea or vomiting. OBJECTIVE To assess the effectiveness of diclofenac rectal suppositories for relief perineal pain after perineorrhaphy. DESIGN A randomized double-blinded placebo controlled trial. MATERIAL AND METHOD Seventy-two term, singleton, pregnant women who gave vaginal birth with second to third degree episiotomy tears were randomized with envelop concealment to either diclofenac or placebo rectal suppositories group. Each group received two tablets of 50 mg diclofenac or two tablets of look-alike placebo rectal suppositories. Visual analogue scale was used for scaling pain score before administration of the medications, and at 30 minutes, 1, 2, 12, and 24 hours after administration. RESULTS No differences were found in the median pain scores before administration of medications and at 30 min, 1 hour and 2 hour after administration (p > 0.05), while the median pain scores were significantly reduced in the diclofenac group at 12 and 24 hours after administration compared to the control group (4.5 vs. 0.0; p < 0.001 and 2.0 vs. 0.0; p = 0.02 for 12 hours and 24 hours, consecutively). CONCLUSION The present study suggested that diclofenac suppository was effective on reducing perineal pain after episiotomy, especially at 12 and 24 hours after administration.

Abstract
OBJECTIVE To determine the prevalence and associate factors for striae gravidarum in Thai pregnant women. STUDY DESIGN Cross-sectional study. MATERIAL AND METHOD Two hundred and eighty women who gave first birth and were admitted to the postpartum wards in Siriraj Hospital were recruited. All of them were assessed during the immediate postpartum period for having striae gravidarum or not by the physician. The questionnaire was used to interview the participants for all of the information needed in the present study. The participants with striae gravidarum and the other without striae gravidarum were compared to characteristics of women using unpaired student t test and Chi-square tests. RESULTS Seventy-seven percent of the study participants had developed striae gravidarum. Women who developed striae gravidarum were significantly younger (22.8 yr +/- 4.0 yr vs. 26.6 yr +/- 6.0 yr; p < 0.05), higher pre-pregnancy BMI (21.2 kg/m2 +/- 4.1 kg/m2 vs. 19.8 kg/m2 +/- 4.8 kg/m2; p < 0.05), higher maternal BMI at pregnancy (27.3 kg/m2 +/- 4.7 kg/m2 vs. 25.6 kg/m2 +/- 6.0 kg/m2; p < 0.05), higher gestational age at delivery (39.1 wk +/- 1.3 wk vs. 38.6 wk +/- 1.1 wk; p < 0.05), higher birth weight of baby (3,078.8 g +/- 411.4 g vs. 2,895.8 g +/- 339.2 g; p < 0.05), alcoholic drinker (91.4% vs. 8.6%; p < 0.05), had a little water intake (7.4 glasses +/- 2.7 glasses vs. 8.3 glasses +/- 3.1 glasses; p < 0.05), and had a family history of striae gravidarum (82.8% vs. 17.2%; p < 0.05) were associated with striae gravidarum. CONCLUSION Maternal age, pre-pregnancy BMI, maternal BMI at delivery, gestational age at delivery, birth weight of baby, alcoholic drinking, water intake and family history were associated with striae gravidarum.

Abstract
OBJECTIVE The main objective was to compare the satisfaction levels of antenatal care between healthy pregnant women who received short message service (SMS) via mobile phone for prenatal support, and those who did not. The second objective was to compare the confidence, anxiety levels and also pregnancy outcomes. DESIGN A randomized controlled trial. MATERIAL AND METHOD 68 healthy pregnant women who attended the antenatal clinic and delivered at Siriraj Hospital, who met the inclusion criterias between May 2007 and October 2007, were enrolled and randomly allocated into two random groups. The study group received two SMS messages per week from 28 weeks of gestation until giving birth. The other group was pregnant women who did not receive SMS. Both groups had the same antenatal and perinatal care. The satisfaction, confidence and anxiety scores were evaluated using a questionnaire at the postpartum ward. The pregnancy outcomes were also compared in these two groups. RESULTS The satisfaction levels of the women who received prenatal support in SMS messages, were significantly higher than those of who did not receive the messages both in the antenatal period (9.25 vs. 8.00, p < 0.001) and during labor (9.09 vs. 7.90, p = 0.007). In the SMS using group, the confidence level was'higher (8.91 vs. 7.79, p = 0.001) and the anxiety level was lower (2.78 vs. 4.93, p = 0.002) than the control group n the antenatal period, however no diference in pregnancy outcomes were found. CONCLUSION The present study shows the higher satisfaction level of pregnant women who received SMS via mobile phone during their antenatal service when compared with the general antenatal care group. The study also show the higher confidence level and lower anxiety level in the antenatal period but no difference in pregnancy outcomes.

Abstract
OBJECTIVE To investigate the influence of pre-pregnancy weight on delivery outcome and birth weight in potential diabetic women with normal glucose tolerance. DESIGN Retrospective Cohort study. MATERIAL AND METHOD The medical records of 660 pregnant women, who attended the antenatal clinic and delivered at Siriraj Hospital between January 2003 and December 2005, were reviewed and analyzed. They all had the known pre-pregnancy weight and were at risk of gestational diabetes with the normal glucose tolerance. Any pregnant women without pre-pregnancy weight recorded were excluded from the present study. They were classified into two groups according to the pre-pregnancy BMI, one was the overweight group (BMI > or = 27 kg/m2) and the other was the normal weight group (BMI 20-25 kg/m2). Information of the complications of pregnancy, the route of delivery, birth weight, and neonatal outcomes were collected and analyzed. RESULTS The risks of adverse pregnancy outcomes in overweight women, after adjusting for the confounding factors, were significantly increased, including pre-eclampsia (OR 3.87, 95% CI 2.09-7.25, p < 0.001), cesarean delivery (OR 2.22, 95% CI 1.45-3.39, p < 0.001), cephalopelvic disproportion (OR 2.15, 95% CI 1.35-3.42, p = 0.001), and macrosomia (OR 7.59, 95% CI 1.98-29.09, p < 0.001). CONCLUSION Even though the screening test for gestational diabetes mellitus is normal, the overweight women still have several adverse pregnancy outcomes.

Abstract
AIM To create reference centile charts for liver length, spleen perimeter and umbilical vein maximum flow velocity (UVVmax) in Thai fetuses in order to predict fetal anemia in Thai fetuses. METHODS The study was a prospective, cross-sectional study, carried out at the Division of Maternal-Fetal Medicine, Department of Obstetrics and Gynecology, Faculty of Medicine, Siriraj Hospital, Mahidol University. A total of 780 pregnant women between 13 and 40 weeks' gestation, who attended the antenatal clinic at Siriraj Hospital, Mahidol University, Bangkok, were recruited. Each fetus was measured only once for the purpose of this study. The mean and standard deviation (SD) were estimated at each week of gestation using linear regression modeling. A total of 752 fetuses were measured for fetal liver length, spleen perimeter and UVVmax. Linear regression models were fitted to estimate the mean 95% confidence interval for liver length, spleen perimeter and UVVmax at each gestational age. The centile charts of those parameters were also presented. CONCLUSION Reference centile charts for fetal liver length, spleen perimeter and UVVmax of Thai fetuses were created.

Abstract
OBJECTIVE To evaluate prevalence and intensity of menopausal symptoms, knowledge towards daily life and hormone replacement therapy (HRT) among natural menopause women in Bangkok. DESIGN Cross-sectional, descriptive study. MATERIAL AND METHOD One hundred and sixty two natural menopause women who attended the health seminars or exhibitions except topics about menopause and HRT in Siriraj Hospital from March - June 2005. Targeting women were asked to fill out the structured questionnaires. Data concerning personal history, menopausal symptoms, knowledge of menopause, HRT and daily life in menopause were collected. RESULTS A total of 148 questionnaires (91.4%) were completed for the analyses. Of 148 women, 141 (95.3%) had menopausal symptoms. The most common and most severe menopausal symptom was muscle and joint pains (84.5% and 23.0%, respectively). The majority of the women understood correctly regarding knowledge about menopause issue and daily life during menopause (80.6% and 89.2%, respectively). Although 51.1% of the women showed their knowledge about HRT correctly, only 8.1% were currently using HRT. The main reasons for this low percentage of HRT use were ability to tolerate the menopausal symptoms (49.0%) and lack of correct knowledge about HRT (48.9%). CONCLUSION The most common and also the most severe menopausal symptom in natural menopause women was muscle and joint pains. Most of them demonstrated their correct understandings about menopause issue and daily life in menopause and half of them demonstrated their correct understandings about HRT.

Abstract
OBJECTIVE To establish the centile chart for the ratio of transverse cerebeller diameter to abdominal circumference throughout pregnancy from 13-40 weeks. DESIGN Cross-sectional study. SETTING Department of Maternal - Fetal Medicine, Faculty of Medicine Siriraj Hospital, Mahidol University. SUBJECTS The participants are women with gestational age between 13 and 40 weeks who attend Antenatal Clinic, Siriraj Hospital. MATERIAL AND METHOD A total of 643 pregnant women were recruited in this study. The exclusion criteria were uncertained date of last menstrual period, multiple pregnancies, fetal abnormalities and maternal conditions which could affect fetal growth. Transverse cerebellar diameter and abdominal circumference of all the subjects were measured out by gestational age. The approximately equal numbers of fetuses were measured at each week of gestation. The mean and standard deviation of TCD/AC ratio is estimated at each week of gestation. In addition the 5th, 10th, 50th, 90th and 95th percentiles were calculated at each week of gestation. RESULTS Of 643 pregnant women, 149 (23.1%) were scanned before 20 weeks of gestation and 286 (44.5%) were scanned between 20 and 30 weeks of gestation. The last group was intervened after 30 weeks of gestation. TCD/AC ratio slowly declined from early pregnancy until about 20 weeks then remained stable. After 30 weeks of gestation it started to decline again. CONCLUSION The normal reference value of TCD/AC ratio in Thai fetus were shown in this study. This ratio can be used to calculate gestational age in intrauterine growth restriction fetus.

Abstract
Comparative study of the level of the reported pain between patients who received xylocaine and normal saline for paracervical block during fractional curettage was carried out in 70 patients in a double blind randomized controlled trial. One group of patients received xylocaine for paracervical block just before the procedure was performed while the other group received normal saline in the same manner. Self-reported pain intensity using visual analog scale was assessed at four time points including the first time point when Allis tissue forceps was applied on the cervix, the second and third time points when curettage was done on the endocervix and in the endometrial cavity respectively. The last time point was evaluated at 30 minutes after the procedure. The results of the study revealed pain occurring in patients in the normal saline group was more severe than those in the xylocaine group with statistically significant difference at the second time point (visual analog scale 4.80 +/- 2.7 in the normal saline group compared to 3.20 +/- 2.4 in the xylocaine group, p < 0.05) and third time point (visual analog scale 8.17 +/- 2.0 in the normal saline group compared to 4.94 +/- 3.1 in the xylocaine group, p < 0.05 ). On the contrary, pain occurring in patients in the normal saline group and xylocaine group was not statistically significantly different at the first time point (visual analog scale 3.62 +/- 2.7 in the normal saline group compared to 3.97 +/- 2.8 in the xylocaine group, p > 0.05) and the fourth time point (visual analog scale 1.34 +/- 2.0 in the normal saline group compared to 1.57 +/- 2.6 in the xylocaine group, p > 0.05). Before this study, there was an idea that normal saline solution could be considered for the paracervical injection solution. The explanation for this was the local anesthetic mechanism may be from distension of nerve capsules rather than blockage of specific autonomic nerves. However, this study showed that nerve capsule distension is not the only factor for pain control in paracervical block. An analgesic agent is still an important factor.

Abstract
OBJECTIVE To assess the potential risk factors for birth before arrival at Siriraj Hospital. STUDY DESIGN Prospective case-control study. SETTING Department of Obstetrics & Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol University. SUBJECTS The subjects were 320 patients who had delivered at Siriraj Hospital and were divided into two groups. One hundred and sixty patients, who gave birth before admission to the labor room of Siriraj Hospital, were assigned as the study group. The control group consisted of 160 patients who had normal deliveries in the labor room of Siriraj Hospital at the same period of time. INTERVENTION Information was obtained by interviewing the patients. Both the interviewer and the subjects were blinded to each other. The data were analyzed by using logistic regression model and EpiInfo program. MAIN OUTCOME MEASURE Information of antenatal care, socio-economic data, past obstetric history and present data of delivery. RESULTS The six significant risk factors were identified; education level of the patients (odds ratio 6.11), past history of previous delivery (odds ratio 6.18), past history of preterm delivery (odds ratio 4.03), no antenatal care (odds ratio 8.55), unawareness of true labor symptoms (odds ratio 1.89) and present preterm delivery (odds ratio 2.99). CONCLUSION The risk factors identified from this study were low education level, past history of previous delivery, past history of preterm delivery, no antenatal care, unawareness of symptoms of true labor and present preterm delivery. The risk factors from this study should have further study to get more information that can apply to control birth before arrival.

Abstract
OBJECTIVE To identify maternal and infant morbidity and mortality from birth before arrival at Siriraj Hospital. STUDY DESIGN Prospective case-control study. SETTING Department of Obstetrics & Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol University. SUBJECTS Three hundred and twenty patients, who had delivered at Siriraj Hospital, were divided into two groups. The study group consisted of 160 patients, who gave birth before admission to the labour room of Siriraj Hospital. The control group consisted of 160 patients, who had normal deliveries in the labour room of Siriraj Hospital at the same period of time. INTERVENTION Interviewing the patients and reviewing the medical records of the mothers and infants from both groups. The data were analyzed by using the EpiInfo program. MAIN OUTCOME MEASURE Maternal and infant characteristics after delivery, maternal and infant outcomes including puerperal morbidity, low birth weight, perinatal death and infant morbidity. RESULTS The study showed that the mothers in the study group had to stay in the hospital longer than the control group (3.9 +/- 2.5 days and 3.6 +/- 1.3 days respectively, p < 0.05). The infants in the study group also had to stay in the hospital longer than the control group (5.1. +/- 6.5 days and 3.3 +/- 1.7 days respectively, p < 0.001). The birth weights of infants in the study group were significantly lower than in the control group (2,753.4 +/- 594.1 grams and 3,016.6 +/- 405.0. grams respectively, p < 0.001). The body temperature of the newborns in the study group were also lower than in the control group (36.2 +/- 0.6 degree Celsius and 37.0 +/- 0.4 degree Celsius respectively, p < 0.05). Concerning maternal and infant outcomes, all variables including low birth weight,perinatal death and infant morbidity were better in the control group significantly (p < 0.05) except for puerperal morbidity that had no significant difference (p = 0.77). CONCLUSION From the present study, the authors confirmed the higher mortality and morbidity rate of infants who were born unexpectedly before hospital admission. However, there was no difference in morbidity between the mothers of both groups.

Abstract
OBJECTIVE To report the magnitude of the problem and to evaluate the outcome of maternal illicit drug use in Thai parturients. DESIGN Retrospective case-control study. SETTING Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol University. SUBJECT The subjects were 44,640 parturients who had deliveries at Siriraj Hospital from January 1998 to December 2001 and were divided into two groups. The study group consisted of 66 parturients with a history of illicit drug use and the control group consisted of 44,574 parturients without a history of illicit drug use. INTERVENTION Medical records of 66 parturients with a history of illicit drug use were reviewed. Obstetric statistics of the department were retrieved from the computerized database in the Division of Obstetric and Gynecologic Registry. The data were analyzed using descriptive statistics. MAIN OUTCOME MEASURE Characteristics of parturients, pregnancy outcome, type and incidence of illicit drug. RESULTS Within the study period, 66 cases of maternal illicit drug use were identifiable during the intrapartum period; 65 cases used amphetamine or derivatives and 1 case used an opioid derivative. The number had risen from 1 case in 1998 to 58 cases in 2001. Mean age of the patients was 23.30 +/- 6.04 years. Compared to the control group which included 44,574 parturients, the patients had a lower incidence of antenatal care (ANC rate = 21.21% vs 94.35%; RR = 0.23, 95% CI = 0.14-0.26), a higher incidence of HIV infection (10% vs 2%; RR = 6.09, 95% CI = 2.83-13.12), a higher incidence of birth before arrival (BBA rate = 9.09% vs 1.06%; RR = 8.59, 95% CI = 3.98-18.51), and a lower cesarean section rate (10.60% vs 26.36%; RR = 0.40, 95% CI = 0.20-0.81). There were no serious intrapartum, immediate postpartum and neonatal complication. Fetal outcome included a higher incidence of low birth weight infants (22.73% vs 10.23%; RR = 2.22, 95% CI = 1.42-3.46) and a smaller head circumference than the normal range of Thai fetal biometry (31.85 +/- 1.47 cm). CONCLUSION There is an increasing trend of illicit drug use in Thai parturients. Although the present case series of drug abuse in Thai parturients cannot give the whole picture of maternal drug abuse in the Thai population, the dramatic increase in the identifiable cases during the past 4 years is very alarming. Currently, the outcome of pregnancy in case detected during intrapartum is not much different from that in the general population. However, there are potential risks for the patients and their babies. All medical staffs should be aware of this condition. Careful clinical data gathering and laboratory testing are suggested for prevention of complications and the potential hazards of this problem.

Abstract
INTRODUCTION Placental hypertrophy and reduced fetal growth have been postulated to be an adaptation to maintain placental function in pregnant women with complications such as malnutrition. If this is true, a pregnancy with impaired fetal growth, resulting in a small for gestational age (SGA) infant, should have an increased placental weight to birthweight ratio (placental ratio) compared to those with appropriate for gestational age (AGA) or large for gestational age (LGA) infants. OBJECTIVES To determine the relationship between placental ratio and fetal growth pattern. MATERIAL AND METHOD Labour and delivery data of 1000 deliveries in the Department of Obstetrics & Gynecology, Siriraj Hospital from January 2001 to June 2001 were retrospectively studied to compare the placental ratios among pregnancies with SGA, appropriate for gestational age (AGA) and large for gestational age (LGA) infants. RESULTS From 96 SGA, 804 AGA and 100 LGA cases, a higher placental ratio was found in the SGA group compared to AGA (0.2074 and 0.1985 respectively, p = 0.013). However, actual placental hypertrophy was not found as demonstrated by a lower placental weight in SGA compared with AGA pregnancies of the same birthweight range. There was no significant difference in placental ratio between the LGA and AGA group, the ratios being 0.2020 and 0.1985 respectively (p = 0.260). Although a positive correlation between placental weight and birthweight was observed in the AGA and LGA groups, it was not demonstrated in the SGA infants. This might influence the placental ratio in the SGA group. CONCLUSION SGA pregnancies are associated with an increased placental ratio which appears not to be due to placental hypertrophy. As reduced birthweight has been shown to be correlated to diseases in adult life, whether this association between SGA and an increased placental ratio will have an implication in future obstetric care and prediction of diseases in adult life remains to be elucidated.

Abstract
The safety and efficacy of Trihydroxyethylrutosides (HR) in the treatment of 53 patients with 1st-2nd degree hemorrhoids of pregnancy (16th-34th week) was investigated in a double-blind randomised, placebo controlled trial. The dosage of Trihydroxyethylrutosides was 1 tablet of 300 milligrams twice daily for the first 2 weeks. If the treatment was successful, the treatment was stopped. If the clinical signs or symptoms still persisted, the treatment was continued for another two weeks using the same dosage and re-evaluated at the end of the fourth week after initial treatment. The parameters for efficacy were symptoms (pain, bleeding, exudation and pruritus) and the objective signs on proctoscopy (bleeding, inflammation and dilatation of the hemorrhoidal venous plexus). The study revealed improvement of symptoms in the study group which was better than in the control group after 2 weeks of treatment but the clinical signs were not different. After a further 2 weeks of treatment, the result showed improvement of both clinical signs and symptoms in this study. Only one mild transient side effect was reported in the HR group and there were no drug-related problems in the pregnancies, delivery or the babies.

Abstract
The accuracy of clinical and ultrasound estimation of fetal weight was compared by an analytical cross sectional study. 266 pregnant women who were admitted to the labour room, Siriraj Hospital during the period from February 1, 1999 to March 1, 1999 were included in this study. Fetal weight was estimated in all pregnant women clinically by 2nd year resident physicians and 6th year medical students, followed by ultrasound estimation within 24 hours before delivery. Every estimation was blinded from each other. From the study, clinical estimation by 2nd year resident physicians was comparable with ultrasound estimation and both were significantly more accurate than estimation by 6th year medical students. The proportions of accuracy were 66.7 per cent, 63.3 per cent and 55.3 per cent respectively. Clinical estimation by 2nd year resident physicians tended to have equally over- and underestimation. On the contrary, ultrasound estimation tended to underestimate when the method was inaccurate. Among infants with a birth weight less than 2,500 grams, ultrasound estimation performed slightly better than clinical estimation. However, every method underestimated the fetal weight when an infant weighed more than 4,000 grams. In conclusion, accuracy of clinical estimation of fetal weight by 2nd year resident physicians was comparable to that of ultrasound estimation and may be used as an alternative to ultrasound estimation for pregnant women. However, when the clinical estimate of fetal weight is less than 2,500 grams, ultrasound estimation should be performed for more accurate results and also for assessment of other abnormalities. Careful attention should be paid to infants with a birth weight of more than 4,000 grams since no method can correctly estimate the fetal weight and physicians should be aware of birth trauma.

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.

Abstract
A cross-sectional study was conducted in order to construct a new reference chart for Thai fetal abdominal circumference (AC). A total of 621 normal pregnant women between 12-41 weeks of gestation and their fetuses were recruited. Measurements were made once at a randomly assigned gestational age specifically for the purpose of this study only. Due to unfavorable fetal position in some cases, AC data were available in 615 measurements. Linear regression models were fitted separately to estimate the mean and standard deviation as functions of gestational age. Reference centiles were constructed from both equations, assuming the data were normally distributed. A new reference centiles for AC is presented and compared with previously published data. Our derived centiles were lower than those from Western studies which may partly be due to racial differences. This emphasizes the need to develop fetal biometries charts specifically for each region.
