Dietary pattern and metabolic syndrome in thai adults.

Objectives. To determine the dietary patterns of middle-aged Thais and their association with metabolic syndrome (MetS). Methods. The Thai National Health Examination Survey IV data of 5,872 participants aged ≥30-59 years were used. Dietary patterns were obtained by factor analysis and their associations with Mets were examined using multiple logistic regression. Results. Three major dietary patterns were identified. The first, meat pattern, was characterized by a high intake of red meat, processed meat, and fried food. The second, healthy pattern, equated to a high intake of beans, vegetables, wheat, and dairy products. The third, high carbohydrate pattern, had a high intake of glutinous rice, fermented fish, chili paste, and bamboo shoots. Respondents with a healthy pattern were more likely to be female, higher educated, and urban residents. The carbohydrate pattern was more common in the northeast and rural areas. Compared with the lowest quartile, the highest quartile of carbohydrate pattern was associated with MetS (adjusted odds ratio: 1.82; 95% CI 1.31, 2.55 in men and 1.60; 95% CI 1.24, 2.08 in women), particularly among those with a low level of leisure time physical activity (LTPA). Conclusion. The carbohydrate pattern with low level of LTPA increased the odds of MetS.

Risk factors for cellulitis in patients with lymphedema: a case-controlled study.

Risk factors for cellulitis in lymphedema (LE) have never been evaluated in controlled studies. The objective of this study was to assess the risk factors for cellulitis in patients with LE using a case-controlled study method. Medical records of patients from November 2009 to September 2011 who met the following criteria were retrieved and analyzed: (a) clinical diagnosis of LE of the limb, (b) aged 18 or above, (c) no food allergy history and (d) no medical diagnosis of cancer metastasis. Overall, there were 179 cases of LE with cellulitis. Each case was matched by age (+/- 5 years) and gender with a patient with LE and without cellulitis for controls. Logistic regression with backward selection procedure was used to identify independent risk factors. The area under the receiver operating characteristics (ROC) curve of the final model was calculated. Independent risk factors for cellulitis in patients with LE were percentage difference in circumference of the limb (adjusted odds ratio (AOR)=1.07, 95% confidence interval (CI)=1.04-1.10), primary LE diagnosis (AOR=3.36, 95% CI=1.37-8.22), food-induced complication experiences (FIE: AOR=6.82, 95% CI=2.82-16.51) and systolic blood pressure (AOR=1.02, 95% CI=1.01-1.04). The area under the curve for the model was 0.80 (95% CI=0.75-0.85, p<0.001). No association was observed with hypertension, diabetes mellitus, body mass index and the duration of LE. This first case-controlled study highlights the important roles of dietary factors, percentage difference in circumference of the limb, and systolic blood pressure for developing cellulitis. The results suggest that controlling the percentage difference in circumference of the limb and systolic blood pressure together with restriction of fatty food and meat consumption may result in a decreased incidence of cellulitis among patients with LE.

Model for predicting the burden and cost of treatment in cervical cancer and HPV-related diseases in Thailand.

PURPOSE: Cervical cancer is a significant health burden in many countries. Long-term cost of care is still not well understood. We aimed to evaluate the long-term burden of illness and healthcare resource utilization associated with cervical cancer, cervical intraepithelial neoplasia (CIN) and genital warts from the care provider perspective. METHOD: We developed a health state-transition Markov model to portray the algorithm of treatment of stages of cervical cancer, CIN and genital warts by tracking a hypothetical lifetime cohort of 12-year-old girls. Costs in this study were unit cost; capital costs and labor costs were included in the unit cost for inpatients and out-patients. RESULTS: The highest incidence of CIN and genital warts was observed in women aged 20-30 years old. For cervical cancer, the highest incidence was 45-55 years. Death rate was estimated at 2%, 8%, 84% and 94% in cervical cancer Stage IA1, IA2-IIA, IIB-IVA and IVB, respectively. The estimated mean direct cost per patient with cervical cancer Stage IA1, IA2-IIA, IIB-IVA, IVB, CIN1, CIN2/3 and genital warts were 41,117 Thai Baht ($1,277 US), 97,250 Thai Baht ($3,020 US), 402,683 Thai Baht ($12,506 US), 322,619 Thai Baht ($10,019 US), 5,381 Thai Baht ($167 US), 49,933 Thai Baht ($1.551 US) and 3,585 Thai Baht ($111 US), respectively. Cost for survival or death case was indifferent. The overall lifetime costs from the provider perspective were evaluated at 859.1 million Baht ($26.7 million US) per a cohort of 100,000 women which corresponds to approximately 4,244 million Baht ($131.8 million US) for the current number of Thai 12-year-old girls. CONCLUSIONS: HPV-related diseases impose health and cost burdens in Thailand. The national immunization programme to reduce this burden as well as further research to evaluate the impact is keenly expected.

A comparison of cycle control, efficacy, and side effects among healthy Thai women between two low-dose oral contraceptives containing 20 microg ethinylestradio1/75 microg gestodene (Meliane) and 30 microg ethinylestradio1/75 microg gestodene (Gynera).

The purpose of this study was to compare cycle control, efficacy and side effects of an oral contraceptive containing 20 microg ethinylestradiol and 75 microg gestodene, with a reference preparation containing 30 microg ethinylestradiol combined with 75 microg gestodene. From the study, it was demonstrated that the two regimens had no difference in cycle control, efficacy, and side effects. The occurrence of spotting and breakthrough bleeding was low and was not different between these two preparations. The most common adverse events in both treatment groups were nausea, vomiting, dizziness, and chloasma. There were no statistically significant change in body weight and blood pressure in both groups at the end of study. It is concluded that both preparations are good cycle control, reliable and low side effects oral contraceptives.

Bone mineral density in adolescent and young Thai girls receiving oral contraceptives compared with depot medroxyprogesterone acetate: a cross-sectional study in young Thai women.

This cross-sectional study of bone mineral density in adolescent and young Thai girls receiving oral contraceptives compared with depot medroxyprogesterone acetate was performed to evaluate the differences among these groups. Thirty current OC users and 30 current depot medroxyprogesterone acetate (DMPA) users were included in the study. The mean duration of OC use was 28.8 +/- 3.4 months and of DMPA 24.6 +/- 3.3 months. Dual energy X-ray absorptiometry (DEXA) was used to measure bone mineral density (BMD) at distal and ultradistal forearm of the nondominant side. The BMD of ultradistal forearm of OC users and that of DMPA users were 0.423 +/- 0.048 and 0.403 +/- 0.039 g/cm(2) and at distal forearm of OC and DMPA users were 0.566 +/- 0.043 and 0.571 +/- 0.064 g/cm(2), respectively. However, there were no statistical differences in BMD in these two groups.

Use of Norplant implants in the immediate postpartum period among asymptomatic HIV-1-positive mothers.

A prospective cohort study of Norplant use in the immediate postpartum period among asymptomatic HIV-1-positive women was conducted in Bangkok, Thailand. The objectives of this study were to evaluate side effects and menstrual patterns of the Norplant system in this group. A total of 88 asymptomatic HIV-1-positive mothers were recruited for this study. All of them voluntarily accepted the use of the Norplant implant as a contraceptive method immediately postpartum. Their mean age was 24.9 years. Most of them had completed primary school. The follow-up period was 24 weeks. There were eight participants lost from the study because of loss of contact. Irregular bleeding was the most common menstrual pattern in these participants. The major side effects were headache, followed by hair loss. No subject terminated Norplant use during the study period. The Norplant implant appears to be safe and well tolerated in asymptomatic HIV-1-positive parturients when inserted immediately postpartum.

Unilateral deep vein thrombosis associated with a large myoma uteri. A case report.

BACKGROUND: Deep vein thrombosis is a rare complication of myoma uteri. There have been few reports on this association. CASE: A 42-year-old woman presented with a myoma uteri, 24 weeks in size, that had compressed the pelvic veins and caused unilateral deep vein thrombosis of the left leg. After anticoagulation therapy, a total abdominal hysterectomy was performed, with an uneventful recovery. CONCLUSION: Although deep vein thrombosis associated with myoma uteri is a rare event, it can be managed successfully with anticoagulants and hysterectomy. Myoma uteri with deep vein thrombosis is an indication for hysterectomy.

Efficacy and side effects of Norplant use in Thai women above the age of 35 years.

A prospective study of Norplant implant use in women aged above 35 years was conducted in Bangkok, Thailand. The purposes of this study were to evaluate the efficacy, menstrual patterns, and side effects of Norplant use in these women. A total of 100 women were recruited in a 1-year clinical study. Their mean age was 39.7 years. Most acceptors had completed secondary school. No accidental pregnancy occurred throughout the 1 year of use in this study. The most common menstrual pattern in these acceptors was amenorrhea followed by irregular bleeding. The major side effect was irregular bleeding. There was no significant change in systolic and diastolic blood pressure during the 1 year follow-up period. Thus, Norplant implant use in older women is a safe and effective contraceptive method. This should become another choice for contraception in women aged above 35 years who have contraindications for oral contraceptive use.

New-world and transcultural impact on Thai medical practices and professional behaviour.

Thailand, which is barely recovering from the 1997 economic collapse, has passed a new constitution, has a new government and all of this will have a profound effect on the way doctors practice and interact with their patients. Some of the factors that have been responsible for this are 1) Passage of a patient's rights bill 2) Legal definition of what is a proper consent form 3) The public's demand for openness, better communication and transparency in medicine These concepts, which now have a legal as well as moral basis, will impact directly on doctors and nurses as their practices will be subject to increasingly intense scrutiny and criticism. Doctors and nurses in past generations were among the most respected members of Thai society. They were trusted almost without exception and their judgment was not questioned. Only rare cases of malfeasance and malpractice came to public notice though, no doubt, they existed but to a much lesser degree. A physicians' life was much simpler for our teachers, fathers and grandfathers. Life was inexpensive, families were less demanding and the doctor did not have to surround himself with expensive foreign-made apparatus which can bankrupt the doctor as well as the patients who have to pay the bills. Medical decisions were made mostly on the basis of observation, past experience at the bedside and not in the laboratory or imaging rooms. Honest errors in diagnosis were common, treatment was limited and simple and this was all tolerated or expected by the public. Few if any disappointments on the part of patients ended up before a judge.

Use of depot medroxyprogesterone acetate in Thai adolescents.

Depot medroxyprogesterone acetate (DMPA) has been available for several decades in many parts of the world including Thailand, but few data have been reported concerning adolescents. The aim of the study was to determine the use of DMPA for contraceptive use among Thai adolescents. A cross-sectional study has been designed. A total of 108 adolescents who used DMPA as contraception between January 1, 1996, and December 31, 1997, at King Chulalongkorn Hospital were reviewed by chart. Most of the participants were in late adolescence and average age was 17.6 years of age. Six-month continuation rate was 69.4%, and at 9 months and 1 year were 42.6 and 30.6%, respectively. Irregular bleeding, amenorrhea, and weight gain were the side effects frequently reported. The most common side effect that caused discontinuation within 1 year was irregular bleeding. With prolonged use, the number of cases with irregular bleeding decreased and the duration of bleeding was shortened, whereas the rate of amenorrhea increased. No pregnancy occurred during the study period. In conclusion, DMPA is an effective contraception in adolescents. However, the continuation rate is lower than that for adult women. The main reason for discontinuation is irregular bleeding.

Depot medroxyprogesterone acetate and basal serum prolactin levels in lactating women.

OBJECTIVE: To study the effect of depot medroxyprogesterone acetate on basal serum prolactin levels in lactating women. METHODS: We compared basal serum prolactin levels in 25 lactating women after depot medroxyprogesterone acetate injection and in 25 lactating women of similar age who were using a copper T380A intrauterine device (control group). This sample size was required in order to have 95% power to detect a significant difference. Basal prolactin levels were evaluated by time-resolved fluoroimmunoassay three times (6 weeks postpartum and 3 and 6 weeks after beginning either contraceptive method). RESULTS: At 6 weeks postpartum, before beginning either contraceptive method, the mean prolactin levels in the study and control groups were 991.31 and 948.75 mU/L, respectively (P =.850, 95% confidence interval [CI] -407.57, 492.70). Three weeks later, the mean prolactin levels in the study and control groups were 1156.12 and 860.10 mU/L, respectively (P =.116, 95% CI -76.20, 668.26). At the last follow-up, the mean prolactin levels in the study and control groups were 1127.83 and 710.97 mU/L, respectively (P =.026, 95% CI 51.97, 781.73). There were no significant within-group differences at 6 weeks postpartum before contraception and at 6 weeks after beginning contraception in the study and control groups (P >.05, 95% CI -327.99, 243.02 and -46.76, 522.33, respectively). CONCLUSION: Contraception with depot medroxyprogesterone acetate in lactating women produced higher basal prolactin levels than contraception with copper T380A intrauterine device.

Humanistic learning in medical curriculum.

This paper argues for more attention and exposure to humanistic learning in the Thai medical curriculum. Humanistic learning traditionally consists of literature, history and philosophy, and is advantageous for medical education in that it tends to foster sensitivities to feelings, awareness of social traditions, and creating of skills in deliberating complex, ethical issues. These dispositions are necessary for a doctor in the world where there is an ever increasing public demand for communication, accountability and transparency on the part of doctors. It is proposed that the Thai medical curriculum should include more humanistic learning, and that medical students should be given opportunities to interact more with students from other disciplines throughout their studies and later professional life.
