Background: Childhood asthma is a substantial health burden in Thailand. Due to a lack of pediatric respiratory specialists (pediatric pulmonologists and allergists; RS), most Thai children are cared for by general pediatricians (pediatric primary care providers (PCP)). Objectives: We investigated whether current practices of Thai pediatricians complied with asthma guidelines and compared practices (diagnosis and treatments) provided by PCP and RS. Methods: A cross-sectional study was conducted using electronic surveys including four case scenarios of different asthma phenotypes distributed to Thai pediatricians. Asthma diagnosis and management were evaluated for compliance with standard guidelines. The practices of PCP and RS were compared. Results: From 800 surveys distributed, there were 405 respondents (51%). Most respondents (81%) were PCP, who preferred to use clinical diagnosis rather than laboratory investigations to diagnose asthma. For acute asthmatic attacks, 58% of the pediatricians prescribed a systemic corticosteroid. For uncontrolled asthma, 89% of the pediatricians prescribed at least one controller. For exercise-induced bronchospasm, 55% of the pediatricians chose an inhaled bronchodilator, while 38% chose a leukotriene receptor antagonist (LTRA). For virus-induced wheeze, 40% of the respondents chose an LTRA, while 15% chose inhaled corticosteroids (ICS). PCP prescribed more oral bronchodilators (31% vs. 18%, p = 0.02), antibiotics (20% vs. 6%, p < 0.001), and antihistamines (13% vs. 0%, p = 0.02) than RS for the management of an acute asthmatic attack. Conclusions: Most of the Thai pediatricians' practices toward diagnosis and treatment of acute asthmatic attack and uncontrolled asthma conform to the guidelines. PCP prescribed more oral bronchodilators, antibiotics, and antihistamines than RS. 相似文献

This study aimed to investigate the effects of PM10 concentrations exceeding the Thai national standard (24-hr average, >120 microg/m3) on daily reported respiratory symptoms and peak expiratory flow rate (PEFR) of schoolchildren with and without asthma in Bangkok. The 93 asthmatic and 40 nonasthmatic schoolchildren were randomly recruited from a school located in a highly congested traffic area. Daily respiratory symptoms and PEFR of each child were evaluated and recorded in the diary for 31 successive school days. During the study period, 24-hr average PM10 levels ranged between 46-201 microg/m3. PM10 levels exceeded 120 microg/m3 for 14 days. We found that when PM10 levels were >120 microg/m3, the daily reported nasal irritation of asthmatic children was significantly higher than when PM10 levels were < or =120 microg/m3. In addition, when PM10 levels were >120 microg/m3, nonasthmatic children had a significantly higher daily reported combination of any respiratory symptoms. PEFR did not change with different ambient PM10 levels in both groups. This study suggests that elevated levels of PM10 concentrations in Bangkok affect respiratory symptoms of schoolchildren with and without asthma. 相似文献

Background
Osteoporosis, characterized by low bone mineral density (BMD) and high bone fracture risk, is prevalent in Thai menopausal women. Genetic factors are known to play a key role in BMD. Low density lipoprotein receptor-related protein 5 (LRP5), a co-receptor in the Wnt/beta-catenin pathway, is involved in many aspects of bone biology. As coding single nucleotide polymorphisms (cSNPs) of LRP5, including A1330V (rs3736228), and Asian-related Q89R (rs41494349) and N740N (rs2306862), are associated with lowered BMD, this study aimed to determine the relationship between these LRP5 polymorphisms and BMD in 277 Thai menopausal women.Results
Only rs3736228 deviated from the Hardy–Weinberg equilibrium of allele frequency (p = 0.022). The median, range and p value for the BMD related to each SNP parameter were compared (Mann–Whitney U test). Significant differences were observed between wild-type and risk alleles for both rs3736228 (total radial, p = 0.011; and radial 33, p = 0.001) and rs2306862 (radial 33: p = 0.015) SNPs, with no significant difference for rs41494349 SNP. Linkage disequilibrium was strong for both rs3736228 and rs2306862 SNPs. Haplotype analysis identified high CC frequency in both normal and osteopenia/osteoporosis groups, with a significant odds ratio for carrying the TT haplotype; however, this was non-significant after adjusting for age. Multivariate binary logistic regression analysis performed for rs3736228 showed that individuals with a body mass index <25 kg/m2 had an increased risk of osteoporosis for each decade, but the polymorphism had no effect.Conclusions
This study did not identify LRP5 polymorphisms as a risk factor for osteoporosis in Thai menopausal women. Further studies with larger sample sizes are needed to further clarify the role of LRP5 as a genetic determinant of osteoporosis.14.
A randomized controlled trial of vaginal misoprostol for cervical priming before hysteroscopy. 总被引:2,自引:0,他引:2
OBJECTIVE: To evaluate the effectiveness and side effects of vaginal misoprostol for cervical dilation in nonpregnant women before hysteroscopy. METHODS: Ninety-one women scheduled to have hysteroscopy were randomized to receive either vaginal misoprostol or placebo. Cervical response, outcome of hysteroscopy, and side effects of vaginal misoprostol were assessed. RESULTS: The mean cervical dilatation estimated by Hegar dilator and the mean duration of hysteroscopy were significantly different between the treated group (7.0+/-1.0 mm [range 6-8.5] and 90.0+/-38.4 seconds [range 60-240], respectively) and the control group (3.8+/-1.2 mm [range 2-5.5] and 142.0+/-38.7 seconds [range 60-270]). In the misoprostol group, only three women (6.5%) needed cervical dilation before hysteroscopy, compared with 14 (31.1%) in the placebo group (P = .006). Cervical tears during hysteroscopy occurred in two patients (4.4%) in the control group and none in the misoprostol group. The two most common side effects of vaginal misoprostol were mild lower abdominal pain in 15 women (32.6%) and slight vaginal bleeding in 12 (26.1%). Both side effects were significantly different when compared with placebo (P<.001). CONCLUSION: Vaginal misoprostol lessens the cervical resistance in women undergoing hysteroscopy and facilitates the procedure, with only mild side effects. 相似文献

OBJECTIVE: To ascertain the therapeutic efficacy and safety of hysteroscopic polypectomy in 240 premenopausal and postmenopausal patients. DESIGN: Retrospective study. SETTING: Tertiary university hospital. PATIENT(S): Two hundred forty patients with intrauterine endometrial polyps, who mostly suffered from abnormal uterine bleeding and infertility. INTERVENTION(S): Hysteroscopic polypectomy using various instruments including microscissors, grasping forceps, or electrosurgery either with a monopolar probe or a resectoscope. MAIN OUTCOME MEASURE(S): Operating time, amount of glycine absorption, complications, resumption of normal menstruation, cumulative pregnancy rate, and recurrent rate of polyps after hysteroscopic surgery. RESULT(S): Resectoscopic polypectomy needed more operating time, had more glycine absorption and complications, but less recurrence than other hysteroscopic techniques. The resectoscope had a 0% recurrence rate and that grasping forceps had a 15% recurrence rate. A total of 21 (8.7%) complications occurred, but no major complications were noted. After long-term follow-up of 9 years and 2 months, those with abnormal uterine bleeding resumed normal menstruation in 93.1% and those with infertility had a cumulative pregnancy rate of 42.3%. There was no statistical difference in reproductive outcome between patients having polyps < or = 2.5 cm and >2.5 cm. CONCLUSION(S): We found hysteroscopic polypectomy to be effective, safe, minimally invasive procedure with low rate and mild complications. Restoration of reproductive ability did not depend on the size of the removed lesion. Resectoscopic surgery is more preferable to prevent recurrence of polyps. 相似文献

OBJECTIVE: To determine whether parents' observations can be used to predict the severity of the obstructive sleep apnoea syndrome (OSAS) in children. STUDY DESIGN: Sixty-five children with OSAS diagnosed by overnight polysomnography were consecutively recruited and classified as having severe or non-severe OSAS according to the obstructive apnoea index (OAI) and the oxygen saturation measured by pulse oximetry (SpO2) nadir. Parents were asked to complete a questionnaire about the child's breathing difficulties at night. RESULTS: Twenty-eight patients were classified as severe OSAS and 37 as non-severe OSAS. There were no differences between the two groups with respect to age, sex or body mass index. Male to female ratio was 5:1. Parents of children with severe OSAS more frequently reported observed cyanosis (35 vs 8%; p=0.02); obstructive apnoea (60 vs 35%; p = 0.04); snoring extremely loudly (52 vs 22%; p = 0.01); shaking the child (64 vs 35%; p = 0.02); watching the child during sleep and being afraid of apnoea (85 vs 60%; p = 0.03). However, neither any single nor combinations of observations showed high values for both sensitivity and specificity. CONCLUSIONS: Although some parents' observations are more frequently reported in children with severe OSAS, neither any single nor combinations of observations accurately predict the severity of OSAS. Polysomnography is still needed to determine the severity of obstruction. 相似文献
