Medical ethics for senior medical doctors (episode I).

A good leader will never ever forget themselves, or abuse the power or authority, and also not trust only the inner circle voice, nevertheless they have to listen and consider the voice of disagreement from others. Otherwise, they will transform themselves to be a "dictator" unconsciously which is very dangerous and harmful to the democratic ruling system as well as themselves and their family members, as you can see from the past history of foreign countries and even Thailand itself. Thai culture is surrounded and consistes of kindness, mercy and good wishes to each other. The patient is so grateful and appreciates the value of the medical doctor for saving their life. Even although the Western culture is penetrating globally as a business-oriented culture in which medico-legal cases such as patient's rights, the value of the patient's benefit protection and certainly it requires the legal act to get involved eventually. The compromised culture which has been embedded in Thai society for a prolonged period can be changed firmly and gradually because of the usual and regular condition and definitely the good and valued medical doctors is still around. The opportunity of medical doctors to act as a pioneer of the trend and conflicted societies, is responsible to them and it's a great opportunity for Thai medical doctors to reach out to these goals and excellence. The above statements can be found in various media. Is it true that the medical doctors will absolutely be hundred percent good guys and have good luck from time to time? But for sure, even our medical colleagues are very much dedicated and concentrated in their job, as the family members of our medical profession, they have been left out, they have no time to share with or even be responsible to them. Many of our friends in the same profession might feel so sorry or appreciate the term "short-belt situation" or "unexpected" event which might attack us from the society violently and unmercifully.

First trimester umbilical cord and vessel diameters of Thai fetuses.

OBJECTIVE: To establish the reference ranges for first trimester umbilical cord and vessel diameters of Thai fetuses. MATERIAL AND METHOD: A prospective study was performed on normal pregnant women between 10(+0) and 13(+6) weeks of gestation who underwent ultrasound examination. The diameter measurements were obtained by a 7.5 MHz vaginal--or a 3.75 MHz abdominal transducer. Statistics were analyzed using SPSS computer program. RESULTS: Records of 184 pregnancies were analyzed and the outcome demonstrated a strong correlation between umbilical cord diameter and gestational age (r = 0.90; p < 0.001). Umbilical vessel diameters were also correlated with gestational age. CONCLUSION: First trimester umbilical cord and vessel diameters of Thai fetuses are related to gestational age. The presented reference ranges might be useful for further studies, such as prediction of adverse pregnancy outcome or combination with biochemical or other ultrasound markers for fetal aneuploidy screening.

The management of acardiac twins at King Chulalongkorn Memorial Hospital: case series.

Acardiac twin is a rare event with high perinatal mortality rate and the management strategies remain controversial. The authors report 4 cases of twin pregnancies associated with one acardiac twin diagnosed at King Chulalongkorn Memorial Hospital during the period 1993 to 2002. Two cases were expectantly managed and intrauterine interventions were performed in order to occlude umbilical artery of the acardiac twin in 2 cases, by using Guglielmi detachable coil (GDC) embolization and absolute alcohol injection. Overall, the perinatal mortality rate for the pump twin was 50% and the survival rate of expectant management in the present series was 100%. GDC embolization was judged to be technically successful since it completely occluded the circulation to the acardiac twin. However, the pump twin was dead which might have resulted from the compromised state due to cardiac failure. At present, it seems that conservative management with close antenatal surveillance is the treatment of choice when the twin-weight ratios are substantially less than 70%. Invasive techniques should be considered when there is ultrasound evidence of hydramnios or congestive heart failure of the pump twin at a previable gestational age.

Correlation of 4- and 24-hour urine protein in women with initially diagnosed hypertensive disorders in pregnancy.

OBJECTIVE: To determine whether 4-hour urine protein value correlates with 24-hour urine protein value in women with hypertensive disorders in pregnancy. STUDY DESIGN: Cross-sectional study was performed in 38 in-patient pregnant women who were initially diagnosed as having hypertensive disorders in pregnancy. Urine samples were collected within 24 hours in 2 successive periods: the first 4-hour and the next 20-hour urine, in separate containers. The urine volume, urine protein and creatinine concentrations were thus separately measured. The 4- and 24-hour urine proteins were calculated and the correlation between both groups was determined by simple linear regression analysis. RESULTS: A total of 38 patients were recruited into the study, 26 had mild preeclampsia, 5 had severe preeclampsia, and 7 had superimposed preeclampsia. The result of the 4-hour urine protein was found to correlate with those of the 24-hour urine protein for patients with hypertensive disorders in pregnancy (p < 0.001). CONCLUSION: Total protein values of 4-hour samples positively correlated with values of 24-hour samples of patients with hypertensive disorders in pregnancy. This might be modified and used for urine protein collection in outpatients to improve the compliance.
