Prevalence of Suspected Cholangiocarcinoma Based on Ultrasonography Screening and its Associated Factors in Northeastern Thailand.

Background Ultrasonography of the liver allows detection of liver mass and bile duct dilatation which are findings of suspected Cholangiocarcinoma so that early stage Cholangiocarcinoma can be detected. Objective To estimate the prevalence of suspected Cholangiocarcinoma as well as its associated factors. Method These reported results were obtained from the baseline screening for Cholangiocarcinoma as of July 2013 of an ongoing project the Cholangiocarcinoma Screening and Care Program conducted in Northeastern Thailand. Participants were northeasterners who were at least one of the followings: 40 years or older, ever been infected with liver fluke, ever been treated with praziquantel, or ever been consumed raw fresh water fish. Ultrasonography was done by well-trained medical radiologists. Result Of the total 1,196,685 participants, 58.9% were females with a mean age of 58.2 (standard deviation ± 9.9) years. Suspected Cholangiocarcinoma was found in 15,186 (2.6%; 95% CI: 2.56 to 2.65) individuals. The results observed that the participants with higher age group had high association as compared to younger age group (AOR=1.98; 95% CI: 1.77 to 2.21; p-value < 0.001), hepatitis B infected participants were highly significant as compared to the non- hepatitis B infected (AOR=1.22; 95% CI: 1.07 to 1.39; p-value = 0.002) and participants having Hepatitis C were also significantly associated with Cholangiocarcinoma infection (AOR=1.46; 95% CI: 1.04 to 2.05; p-value = 0.029) based on ultra-sonographic screening respectively. However, patients having diabetes were less likely to be associated with Cholangiocarcinoma (AOR=0.87; 95% CI: 0.81 to 0.93; p-value < 0.001). Conclusion About one out of a hundred cases required further investigations such as Magnetic resonance imaging or Computed Tomography. Early age of ultrasonography screening for Cholangiocarcinoma enhanced the opportunities for early detection of Cholangiocarcinoma and might reduce irrational requests for expensive or invasive methods of diagnosis.

Child-Rearing Practices and its Effect on Cognitive Development of Children at the First Year of Age: The Prospective Cohort Study of Thai Children.

Background Child-rearing during the first year of age has long been known as a strong predictor of child cognitive development, particularly cognitive development. Most studies investigated styles and factors related to child-rearing, but the study of impact of child-rearing practices on child development is limited and unclear. Objective To investigate the child-rearing practices and its effect on cognitive development of children at the age of 12 months, in Thailand. Method This study is part of the prospective cohort study of Thailand. The data were collected via face-to-face interviews and child cognitive development assessment using Capute scale. The multivariable linear regression was used to determine the effect of child rearing practices on child cognitive development. Result Among the total of 4,116 infants. The most common child rearing practices mostly performed by care givers for the responsiveness domains were warmth (96.60%). Concerning demandingness, only proper confrontation was perform by (39.94%). Factor influencing the cognitive development were: Total score; the children who were not reared warmly, had lower Capute score with the mean difference of -7.69, 95% CI: -12.25 to-3.14. For Cognitive Adaptive Test score; the children who were not reared with warmly, had a lower Capute score with the mean difference of -8.11, 95% CI: -14.37 to -1.85. For Clinical Linguistic and Auditory Milestone Scales score; the children who were not reared warmly, had a lower cognitive score with the mean difference of -8.72, 95% CI: -14.74 to -2.69. Do not giving children in proper confrontation had a lower cognitive score than those who were, with the mean difference of -3.06, 95% CI: -5.26 to -0.86. Conclusion When controlled the influence of other variables, raring with warmth was the strongest predictor of child cognitive development.

Self-Efficacy in Child Rearing and Quality of Life among Adolescent Mothers in the Northeast of Thailand.

Background Incidence of adolescent pregnancy has been increasing continuously in Thailand. These adolescent mothers might face various problems such as social acceptance, poor knowledge of child rearing with affect their quality of life. However, there are insufficient studies quality of life and the associated factors of the adolescent mothers in the biggest region, the Northeast of Thailand. Objective To identify the level of quality of life and the association between self-efficacy, ability in child rearing and quality of life of adolescent mothers in the Northeast of Thailand. Method Cross-sectional study with systematic randomization 232 adolescents who gave a first singleton live birth in a hospital, with data collection done through a structured questionnaire administration. The multiple logistic regressions were used to determine the association. Result The majority of postpartum adolescent mothers were age 18 years old (52.59%). All participants were primiparous mothers. Almost all of adolescent mothers had senior relative within family assisting in child rearing (90.95%). Nearly half of them (46.98%) had high scores of quality of life on living and child rearing. Most of the mothers perceived self-efficacy during pregnancy or pre-childbearing in moderate level (87.93%). However, only 36.64% had high level of self-efficacy on living and child rearing. Majority had moderate to high scoring of stress on living and child rearing (65.52%). Only 32.06% received high scoring of social support on living and child rearing. The multiple logistic regressions were used to measure association of significant factors by backward elimination. Factors associated with quality of life in postpartum adolescent mothers were no stress (adjusted odds ratio: AOR = 4.37, 95% CI; 2.29 to 8.30, p-value < 0.001), high level of self-efficacy (AOR = 4.01, 95% CI; 2.04 to 7.88, p-value < 0.001), and high level of social support (AOR = 3.31, 95% CI; 1.74 to 6.31, p-value < 0.001). Conclusion Social support, self-efficacy and stress have strong influences on quality of life of the postpartum adolescent mothers. Therefore relevant sectors should develop system to improve social support and child rearing competency of adolescent since pregnancy and postpartum.

Antibiotic prophylaxis for fourth-degree perineal tear during vaginal birth.

BACKGROUND: One to eight per cent of women suffer third-degree perineal tears (anal sphincter injury) and fourth-degree perineal tear (rectal mucosa injury) during vaginal birth, and these tears are more common after forceps delivery (28%) and midline episiotomies. Fourth-degree tears can become contaminated with bacteria from the rectum and this significantly increases in the chance of perineal wound infection. Prophylactic antibiotics might have a role in preventing this infection. OBJECTIVES: To assess the effectiveness of antibiotic prophylaxis for reducing maternal morbidity and side-effects in fourth-degree perineal tear during vaginal birth. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group Trials Register (30 July 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 2, 2005), MEDLINE (1966 to 15 July 2005), and LILACS (1982 to 15 July 2005). SELECTION CRITERIA: Randomised controlled trials which reported data comparing outcomes of prophylactic antibiotics versus placebo or no antibiotics in fourth-degree perineal tear during vaginal birth. DATA COLLECTION AND ANALYSIS: No trials were found that met the selection criteria. MAIN RESULTS: No randomised controlled trials were identified. AUTHORS' CONCLUSIONS: There are insufficient data to support a policy of routine prophylactic antibiotics in fourth-degree perineal tear during vaginal birth. A well-designed randomised controlled trial is needed.

Vaginal chlorhexidine during labour for preventing maternal and neonatal infections (excluding Group B Streptococcal and HIV).

BACKGROUND: The incidence of chlorioamnionitis occurs in between 8 to 12 women for every 1000 live births and 96% of the cases of chlorioamnionitis are due to ascending infection. Following spontaneous vaginal delivery, 1% to 4% of women develop postpartum endometritis. The incidence of neonatal sepsis is 0.5% to 1% of all infants born. Maternal vaginal bacteria are the main agents for these infections. It is reasonable to speculate that prevention of maternal and neonatal infections might be possible by washing the vagina and cervix with an antibacterial agent for all women during labour. Chlorhexidine belongs to the class of compounds known as the bis-biguanides. Chlorhexidine has antibacterial action against a wide range of aerobic and anaerobic bacteria, including those implicated in peripartal infections. OBJECTIVES: To evaluate the effectiveness and side-effects of chlorhexidine vaginal douching during labour in reducing maternal and neonatal infections (excluding Group B Streptococcal and HIV). SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group trials register (July 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2002), MEDLINE (from 1966 to 2002), EMBASE (from 1980 to 2002), CINAHL (from 1982 to 2002) and LILACS (from 1982 to 2002). SELECTION CRITERIA: Randomized or quasi-randomized trials comparing chlorhexidine vaginal douching during labour with placebo or other vaginal disinfectant to prevent (reduce) maternal and neonatal infections (excluding Group B Streptococcal and HIV). DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial eligibility and quality, extracted and entered the data into the RevMan software and interpreted the data. A third reviewer analysed and interpreted the data. The fourth reviewer also interpreted the data. MAIN RESULTS: Three studies (3012 participants) were included. There was no evidence of an effect of vaginal chlorhexidine during labour in preventing maternal and neonatal infections. Although the data suggest a trend in reducing postpartum endometritis, the difference was not statistically significant (relative risk 0.83; 95% confidence interval 0.61 to 1.13). REVIEWERS' CONCLUSIONS: There is no evidence to support the use of vaginal chlorhexidine during labour in preventing maternal and neonatal infections. There is a need for a well-designed randomized controlled trial using appropriate concentration and volume of vaginal chlorhexidine irrigation solution and with adequate sample size.

Methodological issues in conducting a survey of construction workers in northeastern Thailand.

Social and health problems among the construction workers in Thailand were studied in a multicenter cross-sectional survey. This paper documents methodological issues related to conducting the survey in the northeastern Thailand. These issues include defining suitable sampling frames for building sites and workers and collecting data. A number of practical problems and the approaches to solve them are discussed.

Working and living conditions of construction workers: comparison between large and small construction sites in northeastern Thailand.

This study examined differences in working and living conditions of construction workers in large and small construction sites in Northeastern Thailand. Data were collected by questionnaires, through observation and interviewing. A total of 812 construction workers from 20 large sites and 24 small sites were studied. Working and living conditions among the construction workers were generally poor. However, they were better at the large sites than the small ones. The data suggest an urgent need to improve sanitation and safety conditions on the construction sites and camp sites, including personal protective devices and improved welfare for the workers and their families.

Cefoperazone/sulbactam + co-trimoxazole vs ceftazidime + co-trimoxazole in the treatment of severe melioidosis: a randomized, double-blind, controlled study.

A prospective randomized, double-blind, controlled study of cefoperazone/sulbactam (cefoperazone 25 mg/kg/day) + co-trimoxazole (trimethoprim 8 mg/kg/day) vs ceftazidime (100 mg/kg/day) + co-trimoxazole (trimethoprim 8 mg/kg/day) in the treatment of severe melioidosis was conducted at Srinagarind Hospital, Khon Kaen University, Khon Kaen, Thailand, from July 1995 to September 1996. A total of 84 patients were enrolled in the study. Forty of them (48%) had culture-proven melioidosis and were randomly assigned to one of the two treatment groups, each group with 20 patients. Two cases (one in each treatment group) were excluded from the final analysis due to incomplete data. There was no significant difference in the mortality rate between the two groups-16 per cent (3/19) in the cefoperazone/sulbactam group vs 21 per cent (4/19) in the ceftazidime group (p > 0.05). Bacteriological responses of successfully treated patients were similar in both groups, and both treatment regimens were well tolerated. Cefoperazone/sulbactam + co-trimoxazole can therefore be used as an alternative treatment for severe melioidosis. However, to further support this conclusion, a study with a larger patient population is needed.

Adrenocorticotropin stimulation test in congenital adrenal hyperplasia: comparison between standard and low dose test.

The aim of the study was to compare the response between the standard and low dose adrenocorticotropin (ACTH) test for patients with congenital adrenal hyperplasia (CAH). The authors employed a 2-by-2 crossover design and enrolled 16 patients, 14 girls and 2 boys, aged between 1.4 months and 15 years. Steroid treatment was stopped 24 hours before each test was conducted. The standard ACTH (250 microg) test was performed followed by the low dose test (1 microg) in eight patients; the other eight underwent the low dose ACTH test first followed by the standard one. The cortisol and 17-hydroxyprogesterone (17-OHP) levels in each patient varied unpredictably between the two tests. The cortisol responses to the low dose ACTH at 30 and 60 minutes were lower than at time zero; in contrast to the 60-minute peak cortisol response to the standard dose. The serum 17-OHP in all specimens was more than 10,000 ng/dl (300 nmol/L), with the peak response at 60 minutes in both groups. Both the low dose and standard dose ACTH test indicated adrenal insufficiency and the high 17-OHP levels were diagnostic of 21- hydroxylase (21-OH) deficiency. If the low dose ACTH test becomes the "standard" ACTH test, the diagnosis of 21-OH deficiency would probably not be missed.

Comparison between the antimicrobial susceptibility of Burkholderia pseudomallei to trimethoprim-sulfamethoxazole by standard disk diffusion method and by minimal inhibitory concentration determination.

Melioidosis, an infection caused by Burkholderia pseudomallei, usually occurs in immunocompromised patients and requires prolonged antibiotic therapy. Previously, oral trimethoprim-sulfamethoxazole (TM/SM), an inexpensive and effective drug has been used as a maintenance therapy. The susceptibility of B. pseudomallei to TM/SM by the standard disk diffusion method is very low. However, some patients who were treated with TM/SM as a maintenance therapy despite the in vitro resistance showed good clinical responses. There were no data comparing the susceptibility of B. pseudomallei by the standard disk diffusion method with other quantitative susceptibility tests. The objective of this study was to determine the agreement between the antimicrobial susceptibility of B. pseudomallei to TM/SM by standard disk diffusion and minimal inhibitory concentration determination (MIC). We performed the susceptibility test of 144 strains of B. pseudomallei to TM/SM by both the standard disk diffusion and microbroth dilution MIC. The sensitivity results were 53.5 per cent and 84.0 per cent respectively. The agreement between the 2 tests was very poor (Kappa = 0.14; 95% CI = -0.01 to 0.29). The false resistant rate by the standard disk diffusion test was 67.9 per cent. Further in vitro susceptibility and clinical study are needed to define the interpretive criteria that correlate with clinical response.

A multicentre, randomized, double-blind, placebo-controlled trial of primary cryptococcal meningitis prophylaxis in HIV-infected patients with severe immune deficiency.

OBJECTIVES: To assess the efficacy and survival benefit of low-dose fluconazole (400 mg weekly) for primary prophylaxis for cryptococcal meningitis in patients with advanced HIV infection. METHODS: A prospective multicentre, randomized, double-blind, placebo-controlled study was carried out in HIV-infected patients with CD4 counts <100 cells/microL. RESULTS: Of 90 patients enrolled, 44 received fluconazole and 46 received placebo. The baseline characteristics were similar in the two groups. On an intent-to-treat basis, 10 cases of cryptococcal meningitis developed, three (6.8%) in the fluconazole group and seven (15.2%) in the placebo group. Patients in the placebo group were more likely to develop cryptococcal meningitis than those in the fluconazole group [hazard ratio=2.23; 95% confidence interval (CI): 0.58-8.63; P=0.245]. The survival benefit of fluconazole was greater than that of the placebo. The number of deaths per 10 000 person-days was 2.7 for the fluconazole group (2/7342) and 11.7 for the placebo group (9/7713) (rate difference=9; 95% CI: 0.4-17.5; P=0.046). Based on survival analysis, patients in the placebo group were 4.3 times more likely to die than those in the fluconazole group (95% CI: 0.9-19.8; P=0.065). CONCLUSION: Fluconazole 400 mg once weekly for primary prophylaxis for cryptococcal meningitis in Thailand should be considered in HIV-infected patients, as our study suggested a survival benefit. However, a larger study should be conducted to confirm our findings.

Randomized, double-blind, controlled study of cefoperazone-sulbactam plus cotrimoxazole versus ceftazidime plus cotrimoxazole for the treatment of severe melioidosis.

We conducted a prospective randomized, double-blind, controlled study of cefoperazone-sulbactam (ratio, 1:1; cefoperazone 25 mg/kg/day) plus cotrimoxazole (trimethoprim-sulfamethoxazole [TMP-SMZ] at a ratio of 80:400; TMP, 8 mg/kg/day) versus ceftazidime (100 mg/kg/day) plus cotrimoxazole (TMP, 8 mg/kg/day) for the treatment of severe melioidosis. Of 219 patients enrolled in the study, 102 (47%) had culture-proven melioidosis. These patients were assigned randomly to 2 treatment groups, each with 50 patients (2 patients were excluded). Mortality rates were not significantly different between the 2 groups: 18% in the cefoperazone-sulbactam group versus 14% in the ceftazidime group. The crude difference in the mortality rate was 4%, but when adjusted for type of infection the difference was 0.9% (95% confidence interval, -3.6% to 5.4%; P = .696). The duration of defervescence and the bacteriological response of successfully treated patients were similar in both groups, and both treatment regimens were well tolerated. Cefoperazone-sulbactam plus cotrimoxazole might be used as an alternative to ceftazidime plus cotrimoxazole as treatment for severe melioidosis.

Angina pectoris and coronary artery disease in severe isolated valvular aortic stenosis.

BACKGROUND: Angina pectoris has long been recognised as one of the principal symptoms of severe aortic valve stenosis (AS), even in patients without significant coronary artery disease (CAD). However, controversy exists concerning the prevalence of angina pectoris and associated CAD in such patients. OBJECTIVE: To determine the prevalence of CAD detectable by angiography and its relation to angina pectoris and coronary risk factors in patients with severe AS. PATIENTS AND METHODS: All patients with symptomatic AS who had undergone aortic valve replacement and preoperative cardiac catheterisation at the Austin and Repatriation Medical Centre between 1 January 1986 and 31 May 1996 were retrospectively analysed. Those patients with multiple valve disease, aortic regurgitation of grade 2 or more in severity, or who had had prior coronary artery or valve surgery were excluded from this analysis. RESULTS: A total of 328 consecutive patients with severe AS (242 men and 86 women; mean age 72 years, range 39-84 years) were studied. Significant CAD (reduction in luminal diameter > or = 50%) was found in 162 patients (49.4%). Typical angina was present in 74.7% of these 162 patients but it was also found in 44.6% of the 166 patients without obstructive CAD. Of the patients without angina (n = 133), 30.8% had significant CAD. By multivariate logistic regression, we have identified seven significant predictors for CAD among severe AS patients. Five factors increased risk. Expressed as odds ratio with 95% confidence interval, these included: (i) age in years (1.07; 1.04-1.11, P = 0.001); (ii) male gender (2.09; 1.14-3.80, P = 0.016); (iii) angina pectoris (3.19; 1.89-5.37, P < 0.001); (iv) history of myocardial infarction (2.87; 1.38-5.97, P = 0.005); and (v) peripheral vascular disease (2.28; 1.28-4.05, P = 0.005). Factors associated with decreased likelihood of CAD were serum high density lipoprotein (HDL) cholesterol (0.58; 0.34-0.71, P = 0.002) and peak systolic gradient across the aortic valve (0.97; 0.95-0.99, P = 0.0113). CONCLUSION: Coronary arteriography can probably be omitted for a patient with severe AS if that patient has no symptoms of angina and has no risk factors known to increase its incidence.
