ABSTRACT

Objective:To investigate the safety and effectiveness of endoscopic retrograde cholangiopancreatography (ERCP) for the diagnosis and treatment of pediatric pancreaticobiliary maljunction (PBM).Methods:Data of 40 pediatric patients under 14 with PBM diagnosed and treated by ERCP at Department of Gastroenterology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from November 2012 to September 2022 were collected. PBM types, ERCP-related diagnosis and treatment, adverse events and prognosis were retrospectively analyzed.Results:Nineteen cases were P-B type (joining of common bile duct with pancreatic duct), 17 were B-P type (joining of pancreatic duct with common bile duct), and 4 were complex type. Forty children with PBM underwent 50 ERCP-related operations, among which 48 procedures succeeded. One case failed during cannulation of ERCP, replaced by rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP) afterwards. There were no serious postoperative adverse events such as bleeding, perforation or death. Thirty-four patients (85%) were followed up successfully, among which 14 underwent further surgery and 20 continued conservative treatment.Conclusion:ERCP is the golden standard to diagnose pediatric PBM, and it is also safe and effective treatment for PBM.

ABSTRACT

Objective @#To analyze the epidemiological characteristics and pathogen spectrum of hand,foot mouth disease (HFMD) in Anhui province from 2015 to 2022,and to provide scientific evidence for prevention and control measures of HFMD.@*Methods @# The surveillance data of hand,foot and mouth disease in Anhui province from 2015 to 2022 were analyzed by descriptive epidemiology. Real-time PCR was used to detect and classify HFMD samples. @*Results @#A total of 650 590 HFMD cases were reported in Anhui province from 2015 to 2022,including 1 406 se- vere cases and 17 deaths.The annual reported incidence was 131. 45 /100 000.The epidemic features of“low incidence in odd years and high incidence in even years”were presented from 2015 to 2019.The incidence showed a continuous decline from 2020 to 2022.The monthly distribution showed the characteristics of bimodal epidemic,and the main peak was not obvious in 2020.Hefei,Fuyang,Bozhou,Chuzhou and Suzhou ranked the top five cities in terms of cumulative incidence.The age of onset was mainly distributed in children aged 5 years and below,accounting for 89. 26% of the total cases.The male to female ratio was 1. 48 ∶ 1.A total of 28 657 laboratory-confirmed cases had been reported from 2015 to 2022.EV71 cases accounted for 10. 57% ,Cox A16 cases accounted for 24. 90% ,and other enterovirus cases accounted for 64. 53%.The dominant pathogens showed dynamic changes in different years.Since 2018,the proportion of EV71 decreased significantly,and the proportion of other enteroviruses gradually increased to become the dominant pathogens.Among other enteroviruses,Cox A6 strain was dominant (80. 48% ) .@*Conclusion @# This study suggests that the prevention and control of HFMD in Anhui province should be paid more attention from April to July and from October to December.The focus areas are the cities in northern Anhui and Hefei where the floating population is large.The focus of prevention and control is on children aged 5 years and below.Other enteroviruses have become the dominant pathogens of hand-foot-mouth disease in Anhui province,Cox A6 strain is dominant.

ABSTRACT

Objective To investigate the clinicopathological characteristics and the expression of related molecular markers of heterotopic pancreas for better understanding and avoiding overtreatment of this disease.Methods From 24th March 2009 to 10th November 2016,92 patients with heterotopic pancreas in upper digestive tract diagnosed after endoscopic submucosal dissection(ESD),were collected. Tissues were sectioned and pathologically classified by Heinrich classification.The expressions of seven different molecular markers including cytokeratin(CK)19,insulin,trypsin,Ki-67,p53,CD133 and CD56 were detected by immunohistochemistry staining. Clinical features, pathological features and immunohistochemical results were retrospectively analyzed.Analysis of variance and Kruskal-Wallis test were used.Results According to Heinrich classification,the percentages of type Ⅰ,Ⅱ,and Ⅲ of heterotopic pancreas were 27.2%(25/92),63.0%(58/92)and 9.8%(9/92),respectively.There was no type Ⅳ patients.The heterotopic pancreas mainly located in stomach with proportion being about 91.3%(84/92)of the total heterotopic pancreas.CK19(the marker of pancreas ducts),insulin(as marker of endocrine function)and trypsin(as the marker of exocrine function)were all expressed in heterotopic pancreas.The positive rate of CD56,a pancreatic neuroendocrine marker,was 66.3%(61/92).The umbilicus like depression was the typical endoscopic appearance of heterotopic pancreas,which only found in 29 patients(31.5%).The average rate of Ki-67,cell proliferation index,was(2.08 ± 1.41)%.The expression of mutant p53 was negative in all 92 cases of heterotopic pancreas.The average staining area of CD133,a marker of pancreatic cancer stem cell,was(2.53 ± 2.43)%.The average follow-up period of 92 patients was(43.6 ± 27.5)months.No relapse and malignant change were found and all patients survived after ESD.Conclusions Heterotopic pancreas has normal pancreatic construction and function.The cell proliferation index is low in heterotopic pancreas and no mutant p53 expression is found.The expression of CD133 is also low.Heterotopic pancreas is a congenital benign disease which requires a long-term follow-up rather than overtreatment.

ABSTRACT

Objective To evaluate the potential malignancy, prognosis and risk factors for intraductal papillary mucinous neoplasm(IPMN), which were classified into different risk levels based on Fukuoka guideline. Methods A retrospective analysis of patients with IPMN diagnosed at Nanjing Drum Tower Hospital from 2009 to 2016 was conducted. Clinical characteristics,treatment and prognosis of IPMNs were analyzed. Results A total of 94 IPMN patients were included and divided into 3 groups according to Fukuoka guideline,46 patients in high-risk(HR)group,30 in group of worrisome features(WF), and 18 in low-risk(LR)group. For patients undergoing surgery treatment, there were 5 cases(19.2%,5/26)in HR group and 2 cases(12.5%,2/16)in WF group whose postoperative pathological findings were malignant (P=0.690). The 5-year survival rates after operations were 73.9% and 77.0% in HR and WF group, respectively(P=0.830). For patients without surgery treatment, in a 5-year follow-up, there were 6 cases (33.3%,6/18),2 cases(16.7%,2/12)and 0(0.0%,0/18)progressing into pancreatic cancers in HR, WF and LR groups,respectively(P<0.05). In addition,among the three groups,the 5-year survival rates were 49.5%,85.7% and 100.0%(P=0.025). Jaundice was significantly related to prognosis(P<0.01) and the hazard ratio was 8.883(95%CI:2.953-26.721). Conclusion Jaundice is a predictive risk factor for survival of IPMN. As for the treatment to IPMN, patients in HR group should receive surgery treatment while those in LR group can be followed up. For patients in WF group,the treatment should be customized, with evaluation of predictive risk factors,and operations can be performed when needed.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prevalence and subtypes of microdeletions in azoospermia factor (AZF) region in infertile men from Sichuan in order to correlate genotypes with phenotypes.</p><p><b>METHODS</b>Multiplex-PCR was used to detect sequence tagged sites (STS) of AZF microdeletions in 1011 infertile men including 713 cases of non-obstructive azoospermia and 298 cases of severe oligospermia.</p><p><b>RESULTS</b>The overall prevalence of microdeletions was 10.48% (106/1011), and the deletion rates were 11.08% (79/713) in non-obstructive azoospermia and 9.06% (27/298) in severe oligospermia. Complete AZFa or AZFb deletions were associated with azoospermia, whereas AZFc deletion (60.38%) was the most frequent deletion. The deletions were associated with variable spermatogenic phenotypes, and 37.50% of the patients with a deletion had sperms in the ejaculate. A mild decline in sperm concentration was found in two cases with partial AZFb deletion and one case with partial AZFb-c deletion.</p><p><b>CONCLUSION</b>Deletions of the AZFc region were most commonly found in our patients. All cases with complete AZFa or AZFb deletions and a proportion of cases with AZFc deletion were associated with azoospermia. Our study has provided more insight into the genotype-phenotype correlation, and confirmed that Yq microdeletion screening has a significant value for the diagnosis for male infertility.</p>
