Background: Enterobius vermicularis (pinworm) is a common parasitic intestinal infection in children. A gradual decrease in prevalence of pinworm infection has been noted in resource-rich settings, such as Taiwan. However, the influence of socio-demographic factors on the temporal trend in pinworm infection rates in children under the current pinworm infection prevention policy in Taiwan is not well characterized. This study aimed to evaluate the trend of pinworm infection prevalence and the associated socio-demographic risk factors among children in Hualien County, Taiwan.Methodology: This retrospective longitudinal study included school-aged children in Hualien during 2009–2018. Children were screened for pinworm infection using adhesive cellophane perianal swabs while they were in grades 1 and 4 in school. The factors associated with pinworm infection were analyzed. Trend analysis of pinworm infection rate stratified by sex and residential setting (urban, suburban, and rural) were also performed.Results: A total of 90,730 school-aged children from grades 1 and 4 during 2009–2018 were included. Young age and male sex were risk factors for pinworm infection (P < 0.001). Negative correlation between body mass index (BMI) and enterobiasis was observed and decreased pinworm infection was noted during the study reference period. Children in suburban and rural areas had higher odds ratio for pinworm infection than those in urban areas (suburban: 1.45; rural: 5.27; P < 0.001 for both). Trend analysis revealed a significant decrease in the overall pinworm prevalence rate during 2009–2018 (P for trend: P = 0.953), and it was higher than that in urban and suburban areas.Conclusions: Risk factors for pinworm infection included young age, male, and BMI. High pinworm infection among school-age children in rural areas of Hualien is still an important issue.

ObjectiveScreening and eradication ofHelicobacter pylorihelp reduce disparities in the incidence of gastric cancer. We aimed to evaluate its acceptability and feasibility in the indigenous communities and develop a family index-case method to roll out this programme.DesignWe enrolled residents aged 20–60 years from Taiwanese indigenous communities to receive a course of test, treat, retest and re-treat initial treatment failures with the13C-urea breath tests and four-drug antibiotic treatments. We also invited the family members of a participant (constituting an index case) to join the programme and evaluated whether the infection rate would be higher in the positive index cases.ResultsBetween 24 September 2018 and 31 December 2021, 15 057 participants (8852 indigenous and 6205 non-indigenous) were enrolled, with a participation rate of 80.0% (15 057 of 18 821 invitees). The positivity rate was 44.1% (95% CI 43.3% to 44.9%). In the proof-of-concept study with 72 indigenous families (258 participants), family members of a positive index case had 1.98 times (95% CI 1.03 to 3.80) higher prevalence ofH. pylorithan those of a negative index case. The results were replicated in the mass screening setting (1.95 times, 95% CI 1.61 to 2.36) when 1115 indigenous and 555 non-indigenous families were included (4157 participants). Of the 6643 testing positive, 5493 (82.6%) received treatment. According to intention-to-treat and per-protocol analyses, the eradication rates were 91.7% (89.1% to 94.3%) and 92.1% (89.2% to 95.0%), respectively, after one to two courses of treatment. The rate of adverse effects leading to treatment discontinuation was low at 1.2% (0.9% to 1.5%).ConclusionA high participation rate, a high eradication rate ofH. pyloriand an efficient rollout method indicate that a primary prevention strategy is acceptable and feasible in indigenous communities.Trial registration numberNCT03900910.

This study examined the differences in factors affecting mortality between urban and rural areas in Taiwan. A retrospective study design was adopted by using the older adult health examination data during 2013-2019 from Hualien, Taiwan. The overall mortality risk in rural areas was significantly higher than urban areas. However, there was no significant difference in the mortality risk between the urban and rural older adults with unhealthy behaviors. Betel nut chewing was a significant risk factor of mortality among the rural older adults, while alcohol consumption was a protective factor; smoking, hepatitis C, and mental illness were significant risk factors among the urban older adults. The rural older adults had a higher rate of death from heart disease and lower rate of death from sepsis than the urban older adults. This study highlights the importance of individualized health promotion strategies for urban and rural areas for reducing mortality from disease.

Background: To identify the gastric cancer burden in Indigenous Taiwanese peoples and conduct a project to evaluate how to reduce the disparities most effectively in Indigenous communities. Methods: First, we quantified the gastric cancer burden for Indigenous peoples using data from Taiwan Cancer and Mortality Registries. Risk factor analyses were carried out based on literature review and data from ongoing mass screening for other cancers. Second, we identified parameters that might be associated with Helicobacter pylori infection or help identify a good eradication strategy. Findings: Gastric cancer incidence (24·4 vs. 12·3 per 100,000 person-years) and mortality rates (15·8 vs. 6·8 per 100,000 person-years) were higher in Indigenous peoples than in non-Indigenous, with 2·19-fold (95% Confidence Interval [CI]: 2·06-2·33) and 2·47-fold (2·28-2·67) increased risk, respectively. Despite similar cancer stage at diagnosis, the survival rate in Indigenous peoples was 9·6% (0·1-20·1%) lower. Helicobacter pylori infection is a well-documented risk factor and smoking for >10 years increased the risk by 26·3% (7·9-47·8%). In Indigenous communities, both H. pylori infection (56·1%, 95% CI: 53·6-58·6%) and smoking (28·4%, 95% CI: 25·7-31·0%) were prevalent. Program eradication rates using clarithromycin-based triple therapy were suboptimal (73·7%, 95% CI: 70·0-77·4%); the habits of smoking (1·49-fold, 95% CI: 1·10-2·02) and betel nut chewing (1·40-fold, 95% CI: 1·03-1·89) were associated with the higher risk of treatment failure. Interpretation: Gastric cancer burden is higher in Indigenous Taiwanese than in their non-Indigenous counterparts. Eliminating risk factors, including H. pylori eradication and smoking cessation, is a top priority to reduce this health disparity. Funding: Health Promotion Administration, Ministry of Health and Welfare, Taiwan. Declaration of Interest: The authors report no conflicts of interest. Ethical Approval: The Research Ethics Committee of National Taiwan University Hospital (201804108RINB) and the Council of Indigenous Peoples in Taiwan (1070056368) approved the protocol for this program. The informed consent has been obtained from each participant.

Background The current consensus does not support the use of booster dose because of its anamnestic response in almost all children 15 years after universal infant hepatitis B virus (HBV) vaccination. However, in our clinical setting, numerous concerned parents request a booster administration for their children. We aimed to provide the possible predictors of booster response in adolescents before this booster administration. Methods This study comprised a series of cross-sectional serological surveys of HBV markers in 15-year-old individuals between 2008 and 2012. Data on serum hepatitis B surface antigen, hepatitis B surface antibody (anti-HBs), and liver-function biomarkers in a total of 887 senior high-school students were collected. There were two parts to this study: HBV seroepidemiology and booster-response analysis to identify the possible response predictors and decay factors after the HBV booster administration. Results The overall anti-HBs and hepatitis B surface antigen seropositivity rates were 34.7% and 0.7%, respectively, and the median anti-HBs titer was 3.3 mIU/mL. Six weeks after one dose of recombinant HBV vaccine, the overall booster-response rate in the double-seronegative recipients was 94% (471/501). Among the participants whose initial anti-HBs titers were undetectable or low, 72.4% (247/341) and 95.6% (153/160), respectively, reactivated their anti-HBs titers ≥ 100 mIU/mL about 6 weeks after the booster administration. The likelihood of postbooster anti-HBs titer reaching an adequate protective level increased with the prebooster titer. The female participants had stronger anamnestic responses compared to the male participants. Conclusion We found that the female participants and prebooster anti-HBs titers above the detection limit of the immunoassay were good predictors of HBV booster response.

A 1-year-10-month-old boy was admitted to our pediatric intensive care unit due to near drowning with pulmonary edema. A conventional ventilator with 100% oxygen supplementation was used initially, but was shifted to high frequency oscillatory ventilation as his oxygen saturation was around 84–88%. Therapeutic hypothermia was applied due to hypoxic ischemic encephalopathy with severe acidosis. His respiratory condition improved and he was extubated successfully on the 6th hospital day. The patient had no obvious neurological defects and he was discharged in a stable condition after 17 days of hospitalization. Our case report demonstrates the advantages of therapeutic hypothermia on survival and neurological outcomes in treating pediatric near drowning patients.

Background: Pediatric hematuria/proteinuria is a risk factor for chronic kidney disease in later life, and school urinary screening can detect asymptomatic glomerulonephritis in the early stage. This study aimed to evaluate the prevalence of hematuria/proteinuria and its association with different socio-demographic factors among school children in 2013 in Hualien, Taiwan. Methods: A cross-sectional study was conducted among first, fourth, and seventh graders. Health examination results and urinalysis data were analyzed. Logistic regression models were used to the simultaneously analyze the association between the prevalence of hematuria/proteinuria and socio-demographic factors. Results: A total of 9544 students were included. The overall prevalence of hematuria and proteinuria was 4.1% and 5.7%, respectively. Students who were females, of a high grade level, of aboriginal ethnicity, and living in rural areas had higher hematuria risk (all P

Background: DNA vaccines encoding allergens have been developed to prevent or to treat specific IgE responses. Objective: To evaluate the potential preventive and therapeutic effect of DNA vaccines encoding Cyn d 1 alone or combined with different adjuvants on specific allergies. Methods: Recombinant plasmid Cyn d 1 (pCyn d 1) was constructed by insertion of Cyn d 1 cDNA into the vector pcDNA3. BALB/c mice were injected with pCyn d 1 alone or plus adjuvants such as bupivacaine, bestatin, liposome, or CpG. Control mice were treated with pcDNA3 or PBS. They were boosted 3 weeks later and then sensitized twice with recombinant Cyn d 1 and alum. Their serum antibody responses and cytokine profiles of spleen cells were studied. Adoptive transfer of spleen cells of pCyn d 1-vaccinated mice was also performed. Results: Vaccination of mice with pCyn d 1 induced Th1 responses characterized by IgG2a responses and spleen cell secretion of interferon-γ. Vaccination with pCyn d 1 not only prevented the induction of specific IgE responses but also suppressed ongoing IgE responses. The mice receiving untreated, CD4+- or CD8+-depleted spleen cells from pCyn d 1-vaccinated mice all had suppression of IgE responses. Conclusion: This study confirms the prophylactic and therapeutic effects of DNA vaccines encoding Bermuda grass pollen allergen Cyn d 1 on specific IgE responses. Both CD4+ and CD8+ T cells are crucial for the immunomodulatory effect of pCyn d 1 on specific IgE responses.

Biliary atresia is the most common cause of death from liver disease in children. Although the Kasai operation before 60 days of age can significantly improve prognosis, delay in referral and surgery remains a formidable problem worldwide because of difficulties in differentiating it from benign prolonged neonatal jaundice. We established a universal screening system using an infant stool color card to promote the early diagnosis and treatment of biliary atresia. After a pilot regional study in 2002–2003, a national stool color screening system was established by integrating the infant stool color card into the child health booklet given to every neonate in Taiwan since 2004. Within 24 hours of the discovery of an abnormal stool color, this event is reported to the registry center. The annual incidence of biliary atresia per 10,000 live births in 2004 and 2005 was 1.85 (40/216,419) and 1.70 (35/205,854), respectively. The sensitivity of detecting biliary atresia using stool cards before 60 days of age was 72.5% in 2004, which improved to 97.1% in 2005. The national rate of the Kasai operation before 60 days of age increased from 60% in 2004 to 74.3% in 2005. The jaundice-free rate (

Background Sublingual immunotherapy has been recently used for allergic diseases, but its mechanisms are still unclear. Objective To examine the effect of sublingual administration of a native or denatured allergen alone or plus adjuvant on systemic T H 2 responses and mucosal immunity in mice. Methods Naive or sensitized BALB/c mice were sublingually vaccinated biweekly for 3 weeks with ovalbumin (OVA) or urea-denatured OVA (CM-OVA) only or plus adjuvant CpG oligodeoxynucleotides (CpG) or cholera toxin (CT). Two weeks later, their specific serum IgG, IgG1, IgG2a, IgE, and saliva secretory IgA (SIgA) antibody responses and the cytokine profiles of spleen and cervical lymph node cells were investigated. Results Specific SIgA antibody responses were induced by vaccination with CM-OVA plus CpG or CT. Whereas vaccination with CM-OVA and CpG enhanced T H 1 responses but inhibited IgE production, vaccination with CT and CM-OVA or OVA increased cervical lymph node cell production of interleukin (IL) 4, IL-5, and IL-6 and serum IgG1 antibody responses. In previously sensitized mice, sublingual vaccination with OVA or CM-OVA plus CT or CpG stimulated mucosal SIgA antibody responses, but did not enhance ongoing IgE antibody responses. Conclusions Sublingual vaccination with OVA or CM-OVA plus adjuvant CT or CpG all can induce systemic and mucosal immunity, but CM-OVA plus CpG had the best prophylactic and therapeutic effects on IgE antibody production. It is likely that sublingual vaccines may have a role for the prophylaxis and immunotherapy of allergic reactions.

OBJECTIVE. We aimed to detect biliary atresia (BA) in early infancy to prevent additional liver damage because of the delay of referral and surgical treatment and to investigate the incidence rate of BA in Taiwan. METHODS. A pilot study to screen the stool color in infants for the early diagnosis of BA was undertaken from March 2002 to December 2003. We had designed an “infant stool color card” with 7 numbers of different color pictures and attached it to the child health booklet. Parents were then asked to observe their infant's stool color by using this card. The medical staff would check the number that the parents chose according to their infant's stool color at 1 month of age during the health checkup and then send the card back to the stool color card registry center. RESULTS. The average return rate was ∼65.2% (78184 infants). A total of 29 infants were diagnosed as having BA, and 26 were screened out by stool color card before 60 days of age. The sensitivity, specificity, and positive predictive value were 89.7%, 99.9%, and 28.6%, respectively. Seventeen (58.6%) infants with BA received a Kasai operation within 60-day age period. The estimated incidence of BA in screened newborns was 3.7 of 10000. CONCLUSIONS. The stool color card was a simple, efficient, and applicable mass screening method for early diagnosis and management of BA. The program can also help in estimating the incidence and creating a registry of these patients.

Background. The transmission routes of Helicobacter pylori and hepatitis A virus (HAV) infections have been extensively discussed in previous literature. However, whether H. pylori and HAV shared the same transmission pattern or not remains unclear. Lower socioeconomic status was recognized as a consistent risk factor to both infections. However, whether fecal-oral transmission was a risk factor to both infections is still under debate. Materials and Methods. In 1996, we conducted a cross-sectional study to evaluate the seroprevalence of antibody to H. pylori and HAV among the randomly selected school-aged children (age between 13 and 15) on Green Island (n = 91) and Lanyu Island (n = 138) (two isolated neighborhood islands near Taiwan Main Island). Results. The seroprevalence of H. pylori and HAV on the Green Island were 82.4% and 5.5%, respectively. The seroprevalence of H. pylori and HAV on Lanyu Island were 71.0% and 90.6%, respectively. H. pylori seroprevalence of all children and the subgroup of 13-year-olds was significantly lower on Lanyu Island than Green Island. However, it was not significantly different in subgroups of 14- and 15-year-olds. HAV seroprevalence was significantly higher on Lanyu Island than Green Island among all children and in each age subgroup. The correlation of H. pylori infection and HAV infection did not demonstrate significant linear correlation on both islands. Conclusions. In conclusion, H. pylori and HAV infections in school-aged children of 13‐15 years of age on Green Island and Lanyu Island did not demonstrate significant correlation. The results of this study imply that H. pylori and HAV may share different transmission routes of infection.

Background Current consensus does not support the use of a universal booster of hepatitis B virus (HBV) vaccine because there is an anamnestic response in almost all children 15 years after universal infant HBV vaccination. We aimed to provide a booster strategy among adolescents as a result of their changes in lifestyle and sexual activity. Methods This study comprised a series of cross-sectional serological surveys of HBV markers in four age groups between 2004 and 2012. The seropositivity rates of hepatitis B surface antigen (HBsAg) and its reciprocal antibody (anti-HBs) for each age group were collected. There were two parts to this study; age-specific HBV seroepidemiology and subgroup analysis, including effects of different vaccine types, booster response for immunogenicity at 15 years of age, and longitudinal follow-up to identify possible additional protection by HBV booster. Results Within the study period, data on serum anti-HBs and HBsAg in a total of 6950 students from four age groups were collected. The overall anti-HBs and HBsAg seropositivity rates were 44.3% and 1.2%, respectively. The anti-HBs seropositivity rate in the plasma-derived subgroup was significantly higher in both 15- and 18-year age groups. Overall response rate in the double-seronegative recipients at 15 years of age was 92.5% at 6 weeks following one recombinant HBV booster dose. Among the 24 recipients showing anti-HBs seroconversion at 6 weeks after booster, seven subjects (29.2%) had lost their anti-HBs seropositivity again within 3 years. Increased seropositivity rates and titers of anti-HBs did not provide additional protective effects among subjects comprehensively vaccinated against HBV in infancy. Conclusions HBV booster strategy at 15 years of age was the main contributor to the unique age-related phenomenon of anti-HBs seropositivity rate and titer. No increase in HBsAg seropositivity rates within different age groups was observed. Vaccination with plasma-derived HBV vaccines in infancy provided higher anti-HBs seropositivity at 15–18 years of age. Overall booster response rate was 92.5% and indicated that intact immunogenicity persisted at least 15 years after primary HBV vaccination in infancy. Booster vaccination of HBV did not confer additional protection against HBsAg carriage in our study.

Objective To study the etiology of short stature in children in eastern Taiwan. Materials and Methods This retrospective study included patients referred to Hualien Buddhist Tzu Chi General Hospital for evaluation of short stature from 2002 to 2008. Data were collected from medical records, and included body height and weight by percentile, maternal history, birth history, past medical history, relevant hematological and biochemical investigations, urinalysis, levels of growth and thyroid hormones, bone age, and genetic study. Results A total of 139 children were enrolled. Sixty (43.2%) were classified as having idiopathic short stature, 48 (34.5%) were attributed to underlying disease such as gastrointestinal disorder or chronic illness, 14 (10.1%) had been small for gestational age at birth and their growth had not caught up with that of their peers, 11 (7.9%) were diagnosed with familial short stature, and 6 (4.3%) were diagnosed with growth hormone deficiency. Conclusion Idiopathic short stature was the most common etiology of short stature in children in eastern Taiwan. The incidence of short stature attributed to underlying disease seems to be higher than in other areas of Taiwan. The percentage of small-for-gestational-age children without catch-up growth was also higher in eastern Taiwan than in other areas.

The incidence of hepatocellular carcinoma (HCC) increases with age, but protective antibody responses decrease with time after infants are immunized against hepatitis B virus (HBV). We investigated whether immunization of infants against HBV prevents their developing HCC as adults. We also searched for strategies to maximize the cancer-preventive effects.We collected data from 2 Taiwan HCC registry systems on 1509 patients (6-26 years old) diagnosed with HCC from 1983 through 2011. Data on history of HBV immunization and prenatal maternal levels of HBV antigens of all HCC patients born after July 1984 were retrieved from the HBV immunization data bank of the Taiwan Center for Disease Control. We collected data on birth cohort-specific populations (6-26 years old) of Taiwan using the National Household Registry System. Rates of HCC incidence per 10(5) person-years were derived by dividing the number of patients with HCC by the person-years of the general population. Relative risks (RR) for HCC were estimated by Poisson regression analysis in vaccinated vs unvaccinated birth cohorts. We stratified patients by age group to evaluate the association of birth cohorts and HCC risks.Of the 1509 patients with HCC, 1343 were born before, and 166 were born after, the HBV vaccination program began. HCC incidence per 10(5) person-years was 0.92 in the unvaccinated cohort and 0.23 in the vaccinated birth cohorts. The RRs for HCC in patients 6-9 years old, 10-14 years old, 15-19 years old, and 20-26 years old who were vaccinated vs unvaccinated were 0.26 (95% confidence interval [CI], 0.17-0.40), 0.34 (95% CI, 0.25-0.48), 0.37 (95% CI, 0.25-0.51), and 0.42 (95% CI, 0.32-0.56), respectively. The RR for HCC in 6- to 26-year-olds was lower in the later vs the earlier cohorts (born in 1992-2005 vs 1986-1992; P.001 and 1986-1992 vs 1984-1986; P .002). Transmission of HBV from highly infectious mothers and incomplete immunization were associated with development of HCC.Based on an analysis of 1509 patients with HCC in Taiwan, immunization of infants against HBV reduces their risk of developing HCC as children and young adults. Improving HBV vaccination strategies and overcoming risk factors could reduce the incidence of liver cancer.

Pygopagus conjoined twins are very rare, and half of all pygopagus twins have other anomalies. This report describes the successful surgical separation of pygopagus twins who had a conjoined thecal sac and an epidermal cyst. Meticulous preoperative planning, development of a model simulator, multispecialty teamwork, and a staged surgery contributed to a successful outcome.

Effects of histamine on the twitch tension, intracellular Na+ activity (aiNa), and action potential were simultaneously and continuously measured in the isolated cardiac papillary muscle of guinea pigs. In the driven fiber at 60 beats/ min, histamine induced a concentration-dependent positive inotropic effect, and apparently increased the amplitude of the action potential and shortened the duration at 3 microM, and significantly decreased aiNa by 6.7% from the control value of 4.5 +/- 0.1 mM (n = 6, p < 0.05) at 0.3 microM. Cimetidine at 10 microM did not produce any significant effect but partially antagonized the action of histamine. The respective concentrations of 1 and 3 microM histamine significantly decreased aiNa by 5.4 and 14.3% from the control 5.6 +/- 0.1 mM (n = 6, p < 0.05) in the presence of 10 microM cimetidine. Chlorpheniramine at 10 microM significantly reduced the twitch tension and aiNa, and prolonged the action potential duration. Histamine at 1 microM increased the twitch tension and decreased aiNa from 4.5 +/- 0.1 to 4.1 +/- 0.1 mM (n = 5, p < 0.05) in the presence of 10 microM chlorpheniramine. The combined application of 10 microM cimetidine and 10 microM chlorpheniramine reduced the twitch tension and abolished most effects of histamine. In high potassium solution (16.2 mM), 1 microM histamine significantly decreased aiNa by 12.9% from the control of 3.1 +/- 0.2 mM (n = 5, p < 0.05). The treatment of 0.5 or 1 microM ouabain increased the tension development and aiNa, and abolished the decrease in aiNa produced by the effect of histamine. The results suggest that histamine can directly stimulate Na-K pump in sarcolemma through means of the activation of both H1- and H2-receptors.

Scrub typhus, a potentially fatal rickettsial infection, is endemic in western Pacific Rims including Taiwan. Most reports have been concerned about mainly adult patients, whereas serologic surveys suggested that as many as one-half of cases of scrub typhus might be in children.We conducted a retrospective study of childhood scrub typhus in our hospital from January 1997 to December 2006. Scrub typhus was diagnosed on the basis of serology tests or polymerase chain reaction (PCR) examination in fifteen children.Fever and chigger bite history were presented in all 15 cases, and eschar lesion was identified in 12 patients (80%). Nine (60%) patients had headache and six (40%) complained of abdominal pain. Three patients (20%) had meningoencephalitis, and two (13%) hemophagocytic syndrome were confirmed by bone marrow biopsy. One patient died of progressive acute respiratory distress syndrome (ARDS) and pulmonary hemorrhage. Myocarditis was revealed in autopsy. All surviving patient responded well to antibiotic therapy, and the average duration to defervescence after treatment was 1.8 days.We conclude that scrub typhus should be taken into consideration among patients of acute systemic febrile illness, especially those with suspected exposure history and typical skin lesion. Although most patients responded well to treatment, severe complications such as meningoencephalitis, interstitial pneumonia, acute respiratory distress syndrome, hemophagocytic syndrome, and myocarditis might lead to morbidity and mortality.

Acute lung injury (ALI) is a major culprit of mortality in endotoxemia. Propofol has been commonly used in critical ill patients for sedation. This experiment attempted to elucidate the effects and possible mechanisms of propofol on the ALI induced by endotoxin. Experimentations were carried out using anesthetized, ventilated rats and isolated perfused rat lungs. Endotoxemia was induced by intravenous lipopolysaccharide (LPS, 10 mg kg(-1)). Various groups of rats received infusion of physiological saline solution (PSS) and LPS. Five min after LPS, propofol at low dose (5 mg kg(-1)h(-1)) or high dose (10 mg kg(-1)h(-1)) was infused for 6h. In isolated perfused rat lungs, PSS, LPS, and propofol (30 or 60 mg kg(-1)) were added into the perfusion circuit. During or after 6h observation, we determined the lung weight (LW)/body weight ratio, LW gain, exhaled nitric oxide (NO) and protein concentration in broncheoalveolar lavage. Lung pathology was evaluated to quantify the lung injury score. Plasma nitrate/nitrite, methyl guanidine (MG), tumor necrosis factor(alpha), and interleukin-1(beta) were examined. Blood leukocytes were counted. Capillary filtration coefficient (K(fc)) was obtained in isolated perfused lungs. Posttreatment of propofol at low or high dose attenuated or prevented the extent of ALI. It also reduced the plasma nitrate/nitrite, MG, and pro-inflammatory cytokines including tumor necrosis factor(alpha) (TNF(alpha)) and interleukin-1(beta) (IL-1(beta)). In the isolated perfused rat lungs, propofol significantly reduced the LPS-induced increase in K(fc). This agent did not affect the leukocytopenia caused by LPS. Accordingly, the effects of propofol on the ALI were not related to leukocyte activation or sequestration. Our results suggest that propofol exerts protective effect on the endotoxin-induced ALI. The mechanisms of actions may be mediated through inhibition on the release of pro-inflammatory cytokines, free radicals and NO. In addition, propofol abrogates the microvascular leakage of water and protein in the lungs. The results imply that the use of propofol in critically ill is not only for sedation, but also useful for the prevention of inflammatory progression and lung damage.

Systemic lupus erythematosus presenting as acute pancreatitis is rare. We report a case of a 12-year-old girl with a 1-year history of systemic lupus erythematosus who developed active pancreatitis. The pancreatitis was first manifested by nausea, vomiting, fever, and abdominal pain. Elevated serum amylase (578 U/L) and lipase levels (5588 U/L), and pancreatic enlargement on ultrasound and computerized tomography confirmed the diagnosis. She responded well to high-dose corticosteroid. The high titer of antinuclear antibodies (1:1280) and low level of complement components (C3, 42.9 mg/dL; C4, 2.3 mg/dL) during the pancreatitis attack suggested that the pancreatitis may have been due to systemic lupus erythematosus exacerbation and not related to drug therapy.

Thirty-six neonates were randomly assigned to 2 groups of 18 neonates each. In the pacifier group, infants were given a pacifier before milk feeding. Newborns in the control group were fed without preprandial use of a pacifier. Doppler measurement of peak systolic velocity, enddiastolic velocity, and Pourcelot resistance index in the superior mesenteric artery was performed in both groups. Peak systolic and end-diastolic velocities were significantly increased after pacifier sucking in the preprandial stage. The resistance index decreased significantly after milk feeding but not after pacifier sucking. The feeding volume was not affected by preprandial pacifier sucking.

Mother-to-infant transmission is the major cause of hepatitis B virus (HBV) infection among immunized children. There has been much debate about screening pregnant women and administering hepatitis B immunoglobulin (HBIG) to newborns. We analyzed the rate of HBV infection among children born to hepatitis B surface antigen (HBsAg)-positive mothers and whether HBIG administration reduces transmission.We analyzed data from 2356 children born to HBsAg-positive mothers, identified through prenatal maternal screens. In addition to HBV vaccines, HBIG was given to all 583 children with hepatitis B e antigen (HBeAg)-positive mothers and to 723 of 1773 children with HBeAg-negative mothers. Serology tests for HBV were performed from 2007 to 2009, when children were 0.5-10 years old.A significantly greater percentage of children with HBeAg-positive mothers tested positive for antibodies against the hepatitis B core protein (16.76%) and HBsAg (9.26%) than children with HBeAg-negative mothers (1.58% and 0.29%, respectively; P.0001 and.001). Among the HBV-infected children, the rate of chronicity also was higher among children with HBeAg-positive mothers than children with HBeAg-negative mothers (54% vs 17%; P = .002). Similar rates of antibodies against the hepatitis B core protein (0.99% and 1.88%; P = .19) and HBsAg (0.14% and 0.29%; P = .65) were noted in children born to HBeAg-negative mothers who were or were not given HBIG. Infantile fulminant hepatitis developed in 1 of 1050 children who did not receive HBIG (.095%).Children born to HBeAg-positive mothers are at greatest risk for chronic HBV infection (9.26%), despite immunization. Administration of HBIG to infants born to HBeAg-negative mothers did not appear to reduce the rate of chronic HBV infection, but might prevent infantile fulminant hepatitis. Screening pregnant women for HBsAg and HBeAg might control mother-to-infant transmission of HBV.

Background To assess the prevalence of obesity and major physical examination items including dental caries, myopia, pinworm, hematuria, and proteinuria among school children in Hualien, Taiwan. In addition, the health status differences between gender, grader, levels of residence urbanization, and body mass index (BMI) were examined. Methods Cross-sectional studies with a total of 11,080 students (age, 7–14 years) in grades 1, 4, and 7 were evaluated for weight, height, routine physical examination, and urine analysis during the 2010 Student Health Examination in Hualien. Frequencies, Chi-square test, and logistic regression were conducted using SPSS. Results Of the 11,080 students evaluated, 1357 (12.2%) were overweight, and 1421 (12.8%) were obese. There were significant differences in overweight/obese prevalence by gender, by grader, and by levels of residence urbanization. Dental caries, myopia, and obesity were the most prevalent health problems among these students (75.6%, 33.0%, and 12.8%, respectively). In crude and adjusted analyses, research results showed that there were significant differences in the prevalence of major physical examination items between different gender, grader, levels of residence urbanization, and BMI groups. Girls had a higher prevalence of dental caries, myopia, and hematuria than boys (all p Conclusion Routine health examination provides an important way to detect students’ health problems. Our study elucidated major health problems among school children in Hualien, Taiwan. In addition, the results also indicated that the prevalence of health problems had a significant relationship with gender, grader, levels of residence urbanization, and BMI. It is suggested that school health interventions should consider students’ health profiles along with their risk factors status in planning.
