A Centralized Report on Pediatric Japanese Encephalitis Cases from Beijing Children's Hospital,2013

Fifteen pediatric cases of suspected Japanese encephalitis （JE） were reported in Beijing Children＇s Hospital during the late summer of 2013. The clinical manifestations in most cases included high fever, seizures, and abnormal magnetic resonance imaging findings. Twelve of 15 cases were laboratory-confirmed as JE cases by pathogen identification. Epidemiological investigations showed that five of the 12 laboratory-confirmed patients had an incomplete JE vaccination history. Follow-up investigations after discharge indicated that seven laboratory-confirmed JE patients without JE vaccinations had relatively poor prognoses, with an average Modified Rankin Scale （MRS） score of 2.6 when compared with the other five laboratory-confirmed, JE-vaccinated patients with an average MRS score of 0.5. The observation of pediatric JE cases among those with a history of JE vaccination warrants further attention.

Mental health and insomnia problems in healthcare workers after the COVID-19 pandemic:A multicenter cross-sectional study

BACKGROUND Healthcare workers(HCWs)are at increased risk of contracting coronavirus disease 2019(COVID-19)as well as worsening mental health problems and insomnia.These problems can persist for a long period,even after the pandemic.However,less is known about this topic.AIM To analyze mental health,insomnia problems,and their influencing factors in HCWs after the COVID-19 pandemic.METHODS This multicenter cross-sectional,hospital-based study was conducted from June 1,2023 to June 30,2023,which was a half-year after the end of the COVID-19 emergency.Region-stratified population-based cluster sampling was applied at the provincial level for Chinese HCWs.Symptoms such as anxiety,depression,and insomnia were evaluated by the Generalized Anxiety Disorder-7,Patient Health Questionnaire-9,and Insomnia Severity Index.Factors influencing the symptoms were identified by multivariable logistic regression.RESULTS A total of 2000 participants were invited,for a response rate of 70.6%.A total of 1412 HCWs[618(43.8%)doctors,583(41.3%)nurses and 211(14.9%)nonfrontline],254(18.0%),231(16.4%),and 289(20.5%)had symptoms of anxiety,depression,and insomnia,respectively;severe symptoms were found in 58(4.1%),49(3.5%),and 111(7.9%)of the participants.Nurses,female sex,and hospitalization for COVID-19 were risk factors for anxiety,depression,and insomnia symptoms;moreover,death from family or friends was a risk factor for insomnia symptoms.During the COVID-19 outbreak,most[1086(76.9%)]of the participating HCWs received psychological interventions,while nearly all[994(70.4%)]of them had received public psychological education.Only 102(7.2%)of the HCWs received individual counseling from COVID-19.CONCLUSION Although the mental health and sleep problems of HCWs were relieved after the COVID-19 pandemic,they still faced challenges and greater risks than did the general population.Identifying risk factors would help in providing targeted interventions.In addition,although a major proportion of HCWs have received public psychological education,individual interventions are still insufficient.

Unraveling the complexities of adolescent depression:A call for action

The adolescent years are a period of profound change,both physically and psychologically.For many,these years are marked by excitement and exploration,but for others,they are fraught with challenges that can lead to significant mental health issues.Depression,in particular,has become an increasingly prevalent concern among adolescents worldwide,and its multifaceted etiology requires a comprehensive approach to understanding and intervention.A recent study on the relationships among negative life events,dysfunctional attitudes,social support,and depressive symptoms in Chinese adolescents offers valuable insights into the complex interplay between various factors contributing to adolescent depression.The authors explore a moderated mediation model to better understand how these factors interact with and contribute to the onset of depression.This article aims to delve into the key findings of the study,highlight its implications for clinical practice,and encourage further research in this critical area.

Time trends and disparities of obesity and related national policies and programs in Nepal:a systematic review

Objective Overweight and obesity prevalence has increased in low-income countries.This study systematically reviewed the obesity trend,disparities,and prevention and control efforts in Nepal.Methods We searched PubMed and Google Scholar for articles and reports published between January 1,2004 and December 31,2022.Additional information on National policies and programs related to obesity prevention was retrieved from governmental websites and consultation with relevant experts.Overweight and obesity were defined using the World Health Organization body mass index cut points.Thirty-two studies and reports were included.Results Overall,overweight and obesity rates increased in all groups in Nepal although nationally representative data remained limited.The combined overweight and obesity(OW/OB)and obesity rates in women aged 15-49 years increased from 8.5%to 22.2%and from 0.9%to 5.1%between 2006 and 2016,respectively.OW/OB and obesity rates in men were 17.1%and 2.5%based on data from the 2016 Demographic and Health Survey.OW/OB rate in under-five children increased from 0.6%to 2.8%between 2006 and 2016.Obesity rates for school-age(5-9 years)boys and girls in 2016 were 2.4%and 2.8%,respectively,and were 1.1%and 1.4%for male and female adolescents aged 10-19 years,respectively.OW/OB prevalence was much higher among women,residents in urban areas and central provinces,and in higher socioeconomic status groups.Projected prevalence of OW/OB and obesity for 2030 in adults aged 15-49 was 44.7%and 8.3%,respectively,while it was 2.2%for OW/OB in preschool children.Policies and direct interventions that specifically focused on obesity prevention and control are limited.Conclusions OW/OB prevalence in Nepal has increased during the past 1.8 decades,disproportionately affecting population groups.Existing interventions mostly focused on undernutrition with some indirect implications for obesity prevention.In the future,Nepal needs to develop population-based programs for obesity prevention.

Association of Human Whole-blood NAD+Levels with Nabothian Cyst

Objective Little is known about the association between whole-blood nicotinamide adenine dinucleotide(NAD^(+))levels and nabothian cysts.This study aimed to assess the association between NAD^(+)levels and nabothian cysts in healthy Chinese women.Methods Multivariate logistic regression analysis was performed to analyze the association between NAD^(+)levels and nabothian cysts.Results The mean age was 43.0±11.5 years,and the mean level of NAD^(+)was 31.3±5.3μmol/L.Nabothian cysts occurred in 184(27.7%)participants,with single and multiple cysts in 100(15.0%)and84(12.6%)participants,respectively.The total nabothian cyst prevalence gradually decreased from37.4%to 21.6%from Q1 to Q4 of NAD^(+)and the prevalence of single and multiple nabothian cysts also decreased across the NAD^(+)quartiles.As compared with the highest NAD^(+)quartile(≥34.4μmol/L),the adjusted odds ratios with 95%confidence interval of the NAD^(+)Q1 was 1.89(1.14–3.14)for total nabothian cysts.The risk of total and single nabothian cysts linearly decreased with increasing NAD^(+)levels,while the risk of multiple nabothian cysts decreased more rapidly at NAD^(+)levels of 28.0 to35.0μmol/L.Conclusion:Low NAD^(+)levels were associated with an increased risk of total and multiple nabothian cysts.

Current Trends of the Prevalence of Childhood Asthma in Three Chinese Cities: A Multicenter Epidemiological Survey

Objective To analyze the prevalence of asthma and asthma related symptoms among children aged 0-14 years in three Chinese cities and to obtain a crude estimation of the trend of childhood asthma prevalence in China. Methods A cross-sectional, population-based survey of prevalence of asthrna was conducted in children aged from 0 to 14 years in 3 major cities of China （Beijing, Chongqing, and Guangzhou） with different geographic locations. All the subjects were randomly selected by a multi-stage sampling method. Three to five schools and kindergartens in 2 urban districts in each city were randomly selected for the survey, and a validated questionnaire that included the core questions of the International Study of Asthma and Allergies in Childhood, Phase III questionnaire and several additional questions were used. All questionnaires were completed by parents or guardians of the selected children. Children whose parents responded affirmatively to the question＂ Has your child ever been diagnosed as asthma by a doctor＂ were recognized as victims of asthma. Results The prevalence of asthma in Beijing, Chongqing, and Guangzhou was 3.15%, 7.45%, and 2.09%, respectively. These values were significantly higher than those obtained 10 years ago in the national epidemiological survey in 2000 which used the same method of investigation and the same diagnotic criteria （x^2=3.938, P=-0.047; 22=73.506, P≤0.001; x^2=11.956, P=0.001, in each city）. Of the asthmatic children 57.21%, 69.91%, and 60.00% had their first attack before the age of 3 in Beijing, Chongqing, and Guangzhou, respectively. Wheezing was the primary clinical manifestation for all asthmatic children, followed by persistent cough and repeated respiratory infections. Both the prevalence of asthma and asthma-related symptoms were statistically higher in males than in females. Conclusion The prevalence of childhood asthma is statistically higher than that 10 years ago in the three Chinese cities.

Human bocavirus in children suffering from acute lower respiratory tract infection in Beijing Children＇s Hospital

Background Human bocavirus （HBoV） is a parvovirus recently found to possibly cause respiratory tract disease in children and adults. This study investigated HBoV infection and its clinical characteristics in children younger than five years of age suffering from acute lower respiratory tract infection in Beijing Children＇s Hospital. Methods Nasopharyngeal aspirates were collected from children suffering from acute lower respiratory tract infection during the winters of 2004 to 2006 （from November through the following February）. HBoV was detected by polymerase chain reaction amplification and virus isolation and the amplification products were sequenced for identification. Results HBoV infection was detected in 16 of 333 study subjects. Coinfections with respiratory syncytial virus were detected in 3 of 16 HBoV positive patients with acute lower respiratory tract infection. The median age for HBoV positive children was 8 months （mean age, 17 months; range, 3 to 57 months）. Among the HBoV positive children, 14 were younger than 3 years old, 9 were younger than 1 year old and 7 were younger than 6 months. These 16 positive HBoV children exhibited coughing and abnormal chest radiography findings and more than 60% of these children had wheezing and fever. Ten children were clinically diagnosed with pneumonia, 2 bronchiolitis, 2 acute bronchitis and 2 asthma. One child died. Conclusions HBoV was detected in about 5% of children with acute lower respiratory infection seen in Beijing Children＇s HosPital. Further investigations regarding clinical and epidemiologic characteristics of HBoV infection are needed.

Stability of a rat model of prehepatic portal hypertension caused by partial ligation of the portal vein

AIM： To study the stability of portal hypertension （PHT） caused by partial ligation of the portal vein ligation （PVL） in a rat model.METHODS： Thirty male adult Wistar rats were divided into two groups： 10 in Group Ⅰ received a sham operation; and 20 in Group Ⅱreceived partial PVL. Portal vein pressure （PVP） was measured at four time periods： before ligation, 2 wk, 6 wk and 10 wk postsurgery. Portal venography, blood sampling and liver and spleen pathological examinations were conducted at 10 wk after surgery.RESULTS： The PVP was 9.15± 0.58 cmH2O before ligation, and increased to 17.32 ±0.63 cmH2O 2 wk after PVL. By repeat measurement of the PVP in each rat, it was shown to remain elevated for 10 wk. There were no significant differences in the pressure measurements at 2 wk, 6 wk and 10 wk. Varices were found mainly in the mesenteric vein 2 wk after PVL, which were more obvious later, while these manifestations were similar at week 6 and week 10. Portal venography demonstrated the varices and collaterals. There was no significant change in liver pathology. The volume of the spleen was enlarged 2-fold after ligation, and the sinus of the spleen was enlarged due to congestion. Significant sinus endothelial cell proliferation was observed, but no evidence of hypersplenia was found on hemogram and biochemical examination.CONCLUSION： These findings suggest that a satisfactory prehepatic PHT rat model can be obtained by partial ligation of the portal vein, and this PHT rat model was stable for at least 10 wk.

Application of MPVR and TL-VR with 64-row MDCT in neonates with congenital EA and distal TEF

AIM:To assess the application of multiple planar volume reconstruction(MPVR) and three-dimensional (3D) transparency lung volume rendering(TL-VR) with 64-row multidetector-row computed tomography (MDCT) in neonates with congenital esophageal atresia (EA) and distal tracheoesophageal fistula(TEF).METHODS:Twenty neonates(17 boys,3 girls) with EA and distal TEF at a mean age of 4.6 d(range 1-16 d) were enrolled in this study.A helical scan of 64-row MDCT was performed at the 64 mm×0.625 mm collimation.EA and TEF were reconstructed with MPVR and TL-VR,respectively.Initial diagnosis of EA was made by chest radiography showing the inserted catheter in the proximal blind-ended esophageal pouch.Manifestations of MDCT images were compared with the findings at surgery.RESULTS:MDCT showed the proximal and distal esophageal pouches in 20 cases.No significant difference was observed in gaps between the proximal and distal esophageal pouches detected by MPVR and TLVR.The lengths of gaps between the proximal and distal esophageal pouches detected by MPVR and TL-VR correlated well with the findings at surgery(R=0.87,P<0.001).The images of MPVR revealed the orifice of TEF in 13 cases,while TL-VR images showed the orifice of TEF in 4 cases.CONCLUSION:EA and distal TEF can be reconstructed using MPVR and TL-VR of 64-row MDCT,which is a noninvasive technique to demonstrate the distal esophageal pouches and inter-pouch distance in neonates with EA and distal TEF.

An Integrated Analysis of Risk Factors of Cognitive Impairment in Patients with Severe Carotid Artery Stenosis

Objective To investigate cognitive dysfunction in patients with carotid artery stenosis(CAS) and potential risk factors related to cognitive-especially memory-dysfunction. Methods Forty-seven patients with carotid artery stenosis were recruited into our study cohort. The Mini-Mental State Examination(MMSE) and the Montreal Cognitive Assessment(MoCA) were adopted to assess cognitive function, the Wechsler Memory Scale(WMS) to assess memory function, high-resolution MRI and enhanced ultrasound to evaluate carotid plaques, and computed tomography perfusion(CTP) imaging to evaluate intracranial blood perfusion. Single-factor analysis and multiple-factor regression analysis were used to analyze potential risk factors of cognitive impairment. Results Mini-Mental State Examination test results showed that 22 patients had cognitive impairment, and MoCA test results showed that 10 patients had cognitive impairment. Analysis of various risk factors indicated that the average memory quotient of female patients was higher than that of males(P = 0.024). The cognitive and memory performance of those with an educational background above high school were significantly better than those of participants with high school or lower(P = 0.045). Patients with abnormal intracranial perfusion performed worse on the MMSE test(P = 0.024), and their WMS scores were significantly lower(P = 0.007). The MMSE scores and the memory quotients were significantly lower in patients with a history of cerebral infarction(MMSE, P = 0.047, memory quotient score, P = 0.018). Conclusion A history of cerebral infarction and abnormal cerebral perfusion are associated with decline in overall cognitive function and memory in patients with carotid stenosis. Being female and having an educational background above high school may be protective factors in the development of cognitive dysfunction.

A Scan of Obesogenic Environments and a Spatial Inference of Obesity Prevalence in Chinese Children and Adolescents: Based on the Chinese Health and Nutrition Survey 2011 Data

Objective To identify the characteristics of Chinese obesogenic environments at a provincial level, infer a spatial distribution map of obesity prevalence in 31 provinces, and provide a foundation for development of policy to reduce obesity in children and adolescents. Methods After scanning obesity data on subjects aged 7-17 years from 12 provinces in the China Health and Nutrition Survey 2011 and environmental data on 31 provinces from the China Statistical Yearbook 2011 and other sources, we selected 12 predictors. We used the 12 surveyed provinces as a training sample to fit an analytical model with partial least squares regression and prioritized the 12 predictors using variable importance in projection. We also fitted a predictive model with Bayesian analysis. Results We identified characteristics of obesogenic environments. We fitted the predictive model with a deviance information criterion of 61.96 and with statistically significant（P 〈 0.05） parameter estimates of intercept [95% confidence interval（CI）： 329.10, 963.11], log（oil）（CI： 13.11, 20.30）, log（GDP）（CI： 3.05, 6.93）, log（media）（CI：-234.95,-89.61）, and log（washing-machine）（CI： 0.92, 5.07）. The total inferred average obesity prevalence among those aged 7-17 was 9.69% in 31 Chinese provinces in 2011. We also found obvious clustering in occurrences of obesity in northern and eastern provinces in the predicted map. Conclusion Given complexity of obesity in children and adolescents, concerted efforts are needed to reduce consumption of edible oils, increase consumption of vegetables, and strengthen nutrition, health, and physical activity education in Chinese schools. The northern and eastern regions are the key areas requiring intervention.

Comparison of diagnostic validity of two autism rating scales for suspected autism in a large Chinese sample

BACKGROUND Autism is the most common clinical developmental disorder in children.The childhood autism rating scale(CARS)and autistic autism behavior checklist(ABC)are the most commonly used assessment scales for diagnosing autism.However,the diagnostic validations and the corresponding cutoffs for CARS and ABC in individuals with suspected autism spectrum disorder(ASD)remain unclear.Furthermore,for suspected ASD in China,it remains unclear whether CARS is a better diagnostic tool than ABC.Also unclear is whether the current cutoff points for ABC and CARS are suitable for the accurate diagnosis of ASD.AIM To investigate the diagnostic validity of CARS and ABC based on a large Chinese sample.METHODS A total of 591 outpatient children from the ASD Unit at Beijing Children’s Hospital between June and November 2019 were identified.First,the Clancy autism behavior scale(CABS)was used to screen out suspected autism from these children.Then,each suspected ASD was evaluated by CARS and ABC.Receiver operating characteristic(ROC)curve analysis was used to compare diagnostic validations.We also calculated the area under the curve(AUC)for both CARS and ABC.RESULTS We found that the Cronbach alpha coefficients of CARS and ABC were 0.772 and 0.426,respectively.Therefore,the reliability of the CARS was higher than that of the ABC.In addition,we found that the correlation between CARS and CABS was 0.732.Next,we performed ROC curve analysis for CARS and ABC,which yielded AUC values of 0.846 and 0.768,respectively.The cutoff value,which is associated with the maximum Youden index,is usually applied as a decision threshold.We found that the cutoff values of CARS and ABC were 34 and 67,respectively.CONCLUSION This result indicated that CARS is superior to ABC in the Chinese population with suspected ASD.

Risk factors for intussusception in children with Henoch-Schönlein purpura:A case-control study

BACKGROUND The etiology of Henoch-Schönlein purpura(HSP)with intussusception remains undefined.AIM To investigate the risk factors for intussusception in children with HSP and gastrointestinal(GI)involvement.METHODS Sixty children with HSP and concomitant intussusception admitted to the Beijing Children’s Hospital of Capital Medical University between January 2006 and December 2018 were enrolled in this study.One hundred pediatric patients with HSP and GI involvement but without intussusception,admitted to the same hospital during the same period,were randomly selected as a control group.The baseline clinical characteristics of all patients,including sex,age of onset,duration of disease,clinical manifestations,laboratory test results,and treatments provided,were assessed.Univariate and multiple logistic regression analyses were performed to identify possible risk factors.RESULTS The 60 children in the intussusception group comprised 27 girls(45%)and 33 boys(55%)and the 100 children in the non-intussusception group comprised 62 girls(62%)and 38 boys(38%).The median age of all patients were 6 years and 5 mo.Univariate and multiple regression analyses revealed age at onset,not receiving glucocorticoid therapy within 72 h of emergence of GI symptoms,hematochezia,and D-dimer levels as independent risk factors for intussusception in children with HSP(P<0.05).CONCLUSION The four independent risk factors for intussusception in pediatric HSP with GI involvement would be a reference for early prevention and treatment of this potentially fatal disease.

Screening of Serum Biomarkers for Distinguishing between Latent and Active Tuberculosis Using Proteome Microarray

Objective To identify potential serum biomarkers for distinguishing between latent tuberculosis infection（LTBI） and active tuberculosis（TB）. Methods A proteome microarray containing 4,262 antigens was used for screening serum biomarkers of 40 serum samples from patients with LTBI and active TB at the systems level. The interaction network and functional classification of differentially expressed antigens were analyzed using STRING 10.0 and the TB database, respectively. Enzyme-linked immunosorbent assays（ELISA） were used to validate candidate antigens further using 279 samples. The diagnostic performances of candidate antigens were evaluated by receiver operating characteristic curve（ROC） analysis. Both antigen combination and logistic regression analysis were used to improve diagnostic ability. Results Microarray results showed that levels of 152 Mycobacterium tuberculosis（Mtb）-antigenspecific IgG were significantly higher in active TB patients than in LTBI patients（P 〈 0.05）, and these differentially expressed antigens showed stronger associations with each other and were involved in various biological processes. Eleven candidate antigens were further validated using ELISA and showed consistent results in microarray analysis. ROC analysis showed that antigens Rv2031 c, Rv1408, and Rv2421 c had higher areas under the curve（AUCs） of 0.8520, 0.8152, and 0.7970, respectively. In addition, both antigen combination and logistic regression analysis improved the diagnostic ability. Conclusion Several antigens have the potential to serve as serum biomarkers for discrimination between LTBI and active TB.

Application of emergency severity index in pediatric emergency department

BACKGROUND： The purpose of triage is to identify patients needing immediate resuscitation, toassign patients to a pre-designed patient care area, and to initiate diagnostic/therapeutic measures asappropriate. This study aimed to use emergency severity index （ESI） in a pediatric emergency room.METHODS： From July 2006 to August 2010, a total of 21 904 patients visited the InternationalDepartment of Beijing Children＇s Hospital. The ESI was measured by nurses and physicians, andcompared using SPSS.RESULTS： Nurses of the hospital took approximately 2 minutes for triage. The results of triagemade by nurses were similar to those made by doctors for ESI in levels 1-3 patients. This findingindicated that the nurses are able to identify severe pediatric cases.CONCLUSION： In pediatric emergency rooms, ESI is a suitable tool for identifying severecases and then immediate interventions can be performed accordingly.

Clinical characteristics of pediatric patients with treatment-refractory Tourette syndrome:An evidence-based survey in a Chinese population

BACKGROUND Tourette syndrome(TS)is a complex neurodevelopmental condition marked by tics,as well as a variety of psychiatric comorbidities,such as obsessivecompulsive disorders(OCDs),attention deficit hyperactivity disorder(ADHD),anxiety,and self-injurious behavior.TS might progress to treatment-refractory Tourette syndrome(TRTS)in some patients.However,there is no confirmed evidence in pediatric patients with TRTS.AIM To investigate the clinical characteristics of TRTS in a Chinese pediatric sample.METHODS A total of 126 pediatric patients aged 6-12 years with TS were identified,including 64 TRTS and 62 non-TRTS patients.The Yale Global Tic Severity Scale(YGTSS),Premonitory Urge for Tics Scale(PUTS),and Child Behavior Checklist(CBCL)were used to assess these two groups and compared the difference between the TRTS and non-TRTS patients.RESULTS When compared with the non-TRTS group,we found that the age of onset for TRTS was younger(P<0.001),and the duration of illness was longer(P<0.001).TRTS was more often caused by psychosocial(P<0.001)than physiological factors,and coprolalia and inappropriate parenting style were more often present in the TRTS group(P<0.001).The TRTS group showed a higher level of premonitory urge(P<0.001),a lower intelligence quotient(IQ)(P<0.001),and a higher percentage of family history of TS.The TRTS patients demonstrated more problems(P<0.01)in the“Uncommunicative”,“Obsessive-Compulsive”,“Social-Withdrawal”,“Hyperactive”,“Aggressive”,and“Delinquent”subscales in the boys group,and“Social-Withdrawal”(P=0.02)subscale in the girls group.CONCLUSION Pediatric TRTS might show an earlier age of onset age,longer duration of illness,lower IQ,higher premonitory urge,and higher comorbidities with ADHD-related symptoms and OCD-related symptoms.We need to pay more attention to the social communication deficits of TRTS.

CLINICAL OBSERVATION ON 80 CHILDREN WITH PEPTIC ULCER TREATED PRIMARILY BY TRADITIONAL CHINESE MEDICINE

Using the empirical recipe of Wang Pengfei (a very experienced TCM doctor) as the main treatment, the authors treated 80 children with peptic ulcer by means of promoting blood circulation, removing blood stasis as well as regulating the flow of qi, alleviating pain, tonify-ing the stomach and reinforcing the spleen. Measures for hemostasis, correction of anemia and other general treatment were also taken. After 8 weeks of treatment, a total effective rate of 92.5% was obtained.

Endoscopic retrograde cholangiopancreatography in the treatment of pancreaticopleural fistula in children

BACKGROUND Pancreaticopleural fistula(PPF)is a rare disease,especially in children.Conservative treatment and surgery are traditional therapies,but surgery is invasive.The emergence of endoscopic retrograde cholangiopancreatography(ERCP)has provided a new noninvasive treatment for PPF and may become the first choice for children with PPF.AIM To explore the treatment response to ERCP for PPF in children.METHODS Seven children with PPF were hospitalized in the Gastroenterology Department of Beijing Children’s Hospital from December 2007 to May 2019.Data on these seven patients’clinical characteristics,diagnosis,treatments,and outcomes were analyzed,and their treatment responses following surgery and ERCP were compared.The correlation between the length of hospital stay and conservative treatment was analyzed.Peer-reviewed articles written in English and Chinese published from January 2009 to December 2019 were obtained from various open data sources and reviewed.RESULTS The seven patients comprised three boys and four girls with a mean age of 6.57±3.26 years.The main symptoms were chest tightness and pain(n=4),intermittent fever(n=3),dyspnea(n=3),and abdominal pain(n=1),and all patients had bloody pleural effusion.All seven patients were diagnosed with PPF by magnetic resonance cholangiopancreatography,and all were initially treated conservatively for a mean of 34.67±22.03 d with a poor response.Among five patients who underwent ERCP,one required surgery because of intubation failure;thus,the success rate of ERCP was 80%.Two patients were successfully treated with surgery(100%).The postoperative hospital stay of the two patients treated by surgery was 20 and 30 d,respectively(mean of 25 d),and that of the four patients treated by ERCP ranged from 12 to 30 d(mean of 19.25±8.85 d).The recovery time after ERCP was short[time to oral feeding,4-6 d(mean,5.33±1.15 d);duration of closed thoracic drainage,2-22 d(mean,13.3 d)].Analysis of previous cases of PPF published worldwide during the past decade showed that the treatment success rate of ERCP is not lower than that of surgery.There was no significant difference in the postoperative hospital stay between surgery(16±10.95 d)and ERCP(18.7±6.88 d,P>0.05).A positive linear correlation was found between the overall hospital stay and ERCP intervention time(R2=0.9992).CONCLUSION ERCP is recommended as the first-choice treatment for PPF in children.ERCP should be performed as early as possible if conditions permit.
