RESUMEN
Pyroptosis is a kind of programmed cell death accompanied by inflammatory responses, which is mainly induced by the Caspase-1/4/5/11 activated mediated via inflammasomes or lipopolysaccharide.Pyroptosis causes the cleavage of various Gasdermin family members, including Gasdermin D, in which a large number of pro-inflammatory factors are released to cause inflammatory responses in various diseases.At present, pyroptosis has not been extensively analyzed in pediatric surgical diseases.This review summarizes the research progress of pyroptosis in pediatric surgical diseases like Hirschsprung′s disease, biliary atresia, neonatal necrotizing enterocolitis, and tumors.It is found that pyroptosis is involved in the occurrence and development of pediatric surgical diseases.The research on the specific mechanism of pyroptosis in pediatric surgical disease and involved signaling pathways contributes to the early diagnosis and treatment of some pediatric surgical diseases.
RESUMEN
Objective To observe the characteristics of infant biliary atresia(BA)missed diagnosis by ultrasound.Methods Data of 72 BA infants missed by ultrasound(false-negative,group A),72 BA infants accurately diagnosed by ultrasound(true-positive,group B)and 72 non BA infants(controls,group C)were retrospectively analyzed.Clinical and ultrasonic features were compared between each 2 groups.Logistic regression analysis was performed to screen the impact factors for diagnosing and missed-diagnosing of BA.Results There were significant differences of total bilirubin,direct bilirubin,gamma glutamyl transpeptidase(GGT)and glutamic-oxaloacetic transaminase(GOT)between group A and C,also of total bilirubin,direct bilirubin and GGT between group B and C(all P＜0.05).Significant differences of the incidences of small gallbladder,gallbladder wall rigidity,poor gallbladder contraction function and fibrous plaques in the hepatic hilum were found between group A and B,of undetected or cystic changes in the gallbladder,gallbladder wall rigidity,poor gallbladder contraction function,fibrous plaques in the hepatic hilum and hepatic hilum cysts were noticed between group A and C(all P＜0.05),as well as of undetected or cystic changes in the gallbladder,small gallbladder,gallbladder wall rigidity,gallbladder wall thickening,poor gallbladder contraction function and fibrous plaques in the hepatic hilum were detected between group B and C(all P＜0.05).There were significant differences of display rate of common bile duct between each 2 groups(all P＜0.05).The lower incidence of fibrous plaques in the hepatic hilum and poor gallbladder contraction function were an impact factors for missed diagnosis of BA(both P＜0.05),while higher GGT,higher incidence of fibrous plaques in the hepatic hilum and poor gallbladder contraction function were all impact factors for diagnosis of BA in group A(all P＜0.05).Conclusion Infant BA missed diagnosis by ultrasound had lower incidence of fibrous plaques in the hepatic hilum and poor gallbladder contractile function.Combining with clinical data was helpful for reducing ultrasonic missed diagnosis of BA in infants.
RESUMEN
Biliary atresia is a severe chronic liver disease in infancy that manifests as destructive inflammatory obstructive cholangiopathy.Recent evidence supports that early Kasai procedure by 30 days of life achieves the greatest likelihood of slowing or preventing the need for liver transplant in biliary atresia patients.Unfortunately,the average age at the time of Kasai procedure is around 60 days of life both in China and abroad.The primary reason for this is that there are many difficulties and challenges in early diagnosis.For example,age stratification should be considered when using GGT levels as a screening tool for biliary atresia in infant less than 30 days.What's more,imaging modality such as US shows lower accuracy in very early stage due to milder pathological change in biliary tract,which post challenges on precision medicine and improving prognosis.This article reviewed different early diagnostic methods of screening for biliary atresia,so as to provide a reference for the early diagnosis of biliary atresia,and help discuss the potential development prospect and research direction in the future.
RESUMEN
ABSTRACT Biliary atresia (BA) is a fibro-obliterative cholestatic disease of infancy. The presence of cartilage in the resected tissue is an uncommon finding. We documented the presence of both mature and immature hyaline cartilage in the portal plate and the wall of the gallbladder in a 2-month-old girl infant with BA who had undergone Kasai portoenterostomy. The presence of cartilage could be part of a heterotopia or an uncommon connective tissue metaplasia. The presence of immature cartilage with the merging of the perichondrium with the soft tissue highlights a metaplastic etiology in the index case.
RESUMEN
Objective:To detect the levels of γ-glutamyl transferase (GGT) in the amniotic fluid of normal pregnancies at 19-23 +6 gestational weeks and to analyze the changes in GGT level with gestational age. Methods:This study retrospectively collected the amniotic fluid supernatant from 383 singleton pregnant women (102, 103, 82, 68 and 28 cases at 19-19 +6, 20-20 +6, 21-21 +6, 22-22 +6, 23-23 +6 weeks of gestation, respectively) who underwent amniocentesis for prenatal diagnosis but had normal genetic diagnosis results in Cheeloo Hospital of Shandong University from January 2021 to September 2022. The levels of GGT in the amniotic fluid supernatant were tested and the statistical parameters including xˉ± s, min-max, median ( M), P1, P2.5, P5, P95, P97.5 and P99 values of GGT levels at each gestational week were calculated. GGT were non-normal data and converted into natural logarithms (lnGGT), and a least square linear regression equation was established to analyze the relationship between lnGGT and gestational week. Results:At 19-19 +6, 20-20 +6, 21-21 +6, 22-22 +6, and 23-23 +6 gestational weeks, the xˉ± s of amniotic fluid GGT were (385.8±235.7), (331.8±219.4), (253.7±197.9), (226.7±166.4), and (155.3±96.8) U/L, and the weekly declines were 14.0%, 23.5%, 10.6%, and 31.5%, respectively; the M values were 311.0, 288.0, 199.0, 160.5, and 105.5 U/L, and the weekly declines were 7.4%, 30.9%, 19.3%, and 34.3%, respectively; the P1- P99 were 67.1-1 404.5, 63.2-1 189.1, 36.0-849.8, 44.0-787.3, and 32.0-375.6 U/L, respectively. lnGGT was negatively correlated with gestational age ( R 2=0.148, P<0.001). Conclusions:In normal pregnancies at 19-23 +6 gestational weeks, GGT levels in amniotic fluid decrease with gestational age. Therefore, gestational age should be considered when establishing the reference value for amniotic fluid GGT in normal pregnancies.
RESUMEN
@#Biliary atresia is one of the commonest causes of prolonged jaundice in neonate, whereas cystic biliary atresia is a rare form of biliary atresia with similar presentation, but a slightly different sonographic finding. Being able to differentiate them radiologically is important as the surgical management is different for these two diagnoses. An ultrasound examination was done for a 2-month-old baby girl with prolonged jaundice with the finding of a cyst along the portal triad, which raised the suspicion for cystic biliary atresia. The diagnosis was confirmed with intraoperative cholangiography (IOC) and Kasai procedure was done. The patient was well after the surgery with resolution of jaundice.
RESUMEN
Objective:To investigate the expression of vitamin D receptor(VDR)in biliary epithelial cells of children with biliary atresia(BA)and explore the correlation between VDR epression levels and clinical pathological prognosis.Methods:A total of 48 BA patients who underwent Kasai surgery in the Pediatric Surgery Department of the Second Affiliated Hospital of Xi′an Jiaotong University from January 2017 to December 2020 with confirmed pathological results were selected as the study subjects.Immunohistochemistry was used to determine the expression of VDR in biliary epithelial cells, and Masson staining was used to determine the degree of liver tissue fibrosis.Based on the VDR expression levels, the 48 BA patients were divided into the significantly low VDR expression group(30 cases)and the normal/high expression group(18 cases).Laboratory testing results within 1 week before Kasai surgery and liver shear wave elastography(SWE)data were collected for all patients.Follow-up was conducted for a period of 0 to 60 months after Kasai surgery or liver transplantation, meanwhile, the occurrence of refractory cholangitis and auto-liver survival time were collected.Results:There was a negative correlation between the degree of liver fibrosis and SWE value in children with BA( r=-0.805, P<0.01).In comparison between the two groups, the significantly low VDR expression group had higher SWE values[(20.57±1.28)kPa vs.(18.02±1.41)kPa, P<0.05], higher liver injury biochemical indicators[ALT(215.8±24.7)U/L vs.(182.6±21.2)U/L, P=0.021; AST(165.4±22.3)U/L vs.(139.6±21.4)U/L, P=0.014], a higher frequency of post-Kasai surgery refractory cholangitis(60.00% vs.22.22%, P=0.037), and a shorter median autologous liver survival time(27.00 months vs.36.00 months, P=0.032)than those in the normal/high expression group. Conclusion:The significant decrease in VDR expression in biliary epithelial cells may serve as an indicator of poor prognosis in BA.
RESUMEN
Objective:To analyze the incidence and risk factors of acute kidney injury in children with biliary atresia after liver transplantation.Methods:The retrospective case-control study was conducted.The clinical data of 115 children with biliary atresia who received liver transplantation for the first time in Beijing Friendship Hospital Affiliated to Capital Medical University from December 2018 to November 2020 were collected.The patients were divided into AKI group ( n=39) and non-AKI group ( n=76) according to the diagnostic criteria of the Kidney Disease Improving Global Outcomes(KDIGO). The differences of clinical indicators between the two groups were compared, and multivariate logistic regression analysis was performed for statistically significant variables ( P<0.05) to further determine the independent risk factors for AKI after liver transplantation. The measurement data of normal distribution were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups.Measurement data with non-normal distribution were represented by M( Q1, Q3), and Mann-Whitney U test was used for comparison between groups.Count data were expressed as cases and percentage, and comparisons between groups were made using Chi-square test or Fisher′s exact test. Results:The incidence of AKI in biliary atresia patients after liver transplantation was 33.9%. Univariate analysis showed that there were statistically significant differences in age ( OR=0.721, 95% CI: 0.553-0.938, P=0.014), preoperative infection ( OR=3.307, 95% CI: 1.294-8.468, P=0.013), PELD score ( OR=1.065, 95% CI: 1.031-1.101, P<0.001), serum creatinine numerical value ( OR=0.745, 95% CI: 0.657-0.858, P<0.001), intraoperative red blood cell transfusion ( OR=1.034, 95% CI: 1.028-1.051, P<0.001) and intraoperative plasma transfusion ( OR=1.055, 95% CI: 1.025-1.086, P=0.002) between the AKI group and the non-AKI group ( P< 0.05). Multivariate logistic regression analysis was performed on the selected indicators by univariate analysis, and the results showed that preoperative infection ( OR=3.763, 95% CI: 1.185-11.945, P=0.025) and low serum creatinine ( OR=0.685, 95% CI: 0.570-0.823, P<0.001), intraoperative red blood cell transfusion ( OR=1.033, 95% CI: 1.015-1.056, P=0.028) was independently associated with postoperative AKI ( P<0.05). The inpatient treatment time in ICU and in hospital between the two groups were statistically significant ( P<0.05). Conclusions:Preoperative infection, low creatinine numerical value and intraoperative red blood cell transfusion are independent risk factors for postoperative AKI in children with biliary atresia. AKI may prolong the time in ICU and in hospital.
RESUMEN
Objective:To investigate the application value of single-port laparoscopic left lateral donor liver acquisition in pediatric living donor liver transplantation (PLDLT).Methods:The retrospective and descriptive study was conducted. The clinical data of the donor and recipient who were admitted to Beijing Friendship Hospital of Capital Medical University for PLDLT in January 2020 were collected. The donor was a male, aged 28 years with body mass as 62 kg, height as 174 cm and body mass index (BMI) as 20.5 kg/m 2. The recipient was the daughter of the donor, aged 1 year with body mass as 9 kg, height as 75 cm and BMI as 16.0 kg/m 2. The donor underwent single-port laparoscopic left lateral donor liver acquisition. The recipient underwent living donor liver trans-plantation by the same operation team. Observation indicators: (1) intraoperative conditions; (2) postoperative conditions; (3) follow-up. Results:(1) Intraoperative conditions. The donor under-went single-port laparoscopic left lateral donor liver acquisition successfully, with the single-port access system being placed through a transumbilical incision. The operation time, the warm ischemia time of the donor liver and volume of intraoperative blood loss were 240 minutes, 3 minutes and 40 mL, respectively, of the donor. The weight of the donor liver was 233.6 g, and the corrected graft-to-recipient body weight ratio was 2.60%. The recipient underwent living donor liver transplantation successfully. (2) Postoperative conditions. The donor began to take liquid diet at postoperative day 1, and results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyltransferase (GGT) and total bilirubin (TBil) of the donor was 239 U/L, 116 U/L, 53 U/L and 22.57 μmol/L. The donor began to take diet with high quality proteins at postoperative day 2, and to get for out-of-bed activities moderately. The donor′s peritoneal drainage fluid was light red at postoperative day 3, and no fluid accumulation was found in the operation area after abdominal B-ultrasound examination, so the peritoneal drainage tube was removed. The donor was discharged at postoperative day 4. The liver function of the recipient recovered to normal level 2 weeks after the operation. (3) Follow-up. The donor was followed up by outpatient examination 2 weeks after discharged, and results of laboratory examination showed that the ALT, AST, GGT and TBil was 44 U/L, 25 U/L, 53 U/L and 9.22 μmol/L, respectively. Neither the donor nor the recipient had complication ≥Ⅱ grade of the Clavien-Dino classification, such as biliary fistula and vascular complication during the 6 months after operation.Conclusion:Single-port laparoscopic left lateral donor liver acquisition can be used into the PLDLT.
RESUMEN
Biliary atresia is a rare infant disease that predisposes patients to liver transplantation and death if not treated in time. However, early diagnosis is challenging because the clinical manifestations and laboratory tests of biliary atresia overlap with other cholestatic diseases. Therefore, it is very important to develop a simple, safe and reliable method for the early diagnosis of biliary atresia. Herein, a novel NIR-II fluorescence probe, HZL2, with high quantum yield, excellent biocompatibility, low cytotoxicity and rapid excretion through the liver and gallbladder was developed based on the oil/water partition coefficient and permeability. A simple fecal sample after injection of HZL2 can be used to efficiently identify the success of the mouse model of biliary atresia for the first time, allowing for an early diagnosis of the disease. This study not only developed a simple and safe method for the early diagnosis of biliary atresia with great potential in clinical translation but also provides a research tool for the development of pathogenesis and therapeutic medicines for biliary atresia.

RESUMEN
In biliary atresia (BA), efforts to prevent premature liver transplantation (LT) are aimed at early diagnosis, timing of Kasai-portoenterostomy (KPE), and centralization of care. This report presents the clinical picture, treatment strategies, and outcomes of BA patients with no previous treatment. A retrospective cohort study (Jan/2001 to Jan/2021) was conducted to evaluate the outcome of patients with BA referred to a single team. Study groups were: 1) Kasai-only group (K-only) n=9), 2) LT-only group (n=7), and 3) Kasai+LT group (K+LT) (n=23). Survival with native liver and overall survival were 22.9 and 94.8%, respectively, at 120 months of follow-up. There was no difference in age at KPE in the K-only group (46.8±21.8 days) vs K+LT (52.1±22 days), P=0.4. Ten (25.6%) patients were babies conceived through in vitro fertilization (IVF). Four IVF patients (40%) presented associated congenital heart disease vs 5 patients (17%) in the remaining group (P=0.14). Two of the IVF patients were premature (<37 weeks). Median maternal age at birth was 35 years (33 to 41 years). Excellent patient survival is expected for patients with BA with the available treatment strategies. IVF+BA was an unexpected prevalent association in this cohort, and further studies are required to better understand these findings.
RESUMEN
Objective:To compare the impact of different portal exposure techniques in the Kasai surgery on children with type Ⅲ. biliary atresia during their different perioperative periods.Methods:A retrospective study was performed on the data of children with type Ⅲ. biliary atresia who underwent Kasai surgery at Fujian Children's Hospital from January 2017 to October 2020. Of 45 children enrolled in this study, there were 24 males and 21 females, aged (71.3±21.0) days. Patients who had left and right branches of the portal vein and the left and right hepatic arteries in the portal area being completely freed and elastically stretched during the Kasai operation were included into the free group ( n=22) and the remaining patients were included in the control group ( n=23). Postoperative hospital stay, postoperative direct bilirubin levels, postoperative complications and transplant-free survival after the Kasai operation were compared between the 2 groups. Results:Postoperative hospital stay of (17.1±4.4) d in the free group was significantly lower than that in the control group (20.1±5.4) d, ( t=2.07, P=0.044). The direct bilirubin level at 3 months after surgery for the control group was 30.0 (109, 108.0)μmol/L, which was significantly higher than that of 14.5 (4.0, 37.5) μmol/L in the free group ( Z=-2.16, P=0.031). Twenty-one patients (91.3%) in the control group had frequent attacks of postoperative cholangitis, compared with 13 patients (59.1%) in the free group. The difference was statistically significant (χ 2=4.69, P=0.030). Eleven surviving patients (47.8%) in the control group did not undergo liver transplantation at one year after surgery, compared with 15 patients (68.2%) in the free group. At two years after surgery, 7 surviving patients (30.4%) in the control group did not undergo liver transplantation compared with 10 patients (45.5%) in the free group. Conclusion:For children with type Ⅲ. biliary atresia, completely freeing the left and right branches of portal vein, and left and right hepatic arteries in the liver portal area, and elastically stretching these vessels to expose the portal area of the liver during Kasai surgery increased surgical safety and reduced hospital stay.
RESUMEN
Objective:To elucidate the current proficiency level in diagnosing pediatric biliary atresia among Chinese sonographers and to identify contributing factors that may influence their diagnostic capabilities.Methods:A cross-sectional internet-based survey was conducted from November 6, 2021, to December 12, 2021. The online questionnaire was disseminated to a national cohort of sonographers via WeChat groups. The survey encompassed three domains: demographic data of the participants, clinical and ultrasonographic knowledge pertaining to biliary atresia, and the cognitive understanding of biliary atresia. Descriptive statistics were utilized for the evaluation of demographic information and sonographers' clinical and ultrasonographic comprehension concerning biliary atresia. A generalized linear model was employed to ascertain the determinants influencing sonographers' expertise in clinical management and ultrasonographic diagnosis of biliary atresia.Results:A total of 511 valid responses were collated. Approximately 64.77% (331/511) of sonographers indicated a lack of comprehensive understanding of the essential parameters for ultrasonographic diagnosis of biliary atresia. Regression analysis revealed that sonographers affiliated with lower-tier hospitals ( β=-0.344, P=0.002), non-pediatric institutions ( β=-0.747, P=0.004), and those with less than 15 years of professional experience ( β=0.952, P<0.001) exhibited diminished proficiency in diagnosing biliary atresia. Upon encountering suspected cases, a mere 5.48% (28/511) of sonographers expressed complete confidence in their diagnostic capabilities. Lower professional grade ( β=-0.572, P<0.001) and lack of prior experience with suspected cases of biliary atresia ( β=-0.693, P<0.001) contributed to reduced diagnostic self-assurance among sonographers. Regarding the clinical and ultrasonographic intricacies associated with biliary atresia, only 3.33% (17/511) of sonographers had a full understanding of the diagnostic significance of hepatic fibrous plaques on ultrasound for biliary atresia. Conclusion:The study underscores a pervasive inadequacy in the understanding and diagnostic confidence among sonographers in relation to pediatric biliary atresia. Various pragmatic factors, including hospital tier, years of experience, and professional ranking, exert a direct impact on the sonographers' diagnostic acumen. Given these findings, there is an exigent need for targeted educational initiatives to enhance the diagnostic proficiency in biliary atresia among sonographers.
RESUMEN
Objective:To identify the risk factors for postreperfusion syndrome (PRS) during living donor liver transplantation in pediatric patients with biliary atresia.Methods:The clinical data from pediatric patients who underwent living donor liver transplantation from January 2020 to December 2021 in our hospital were retrospectively analyzed. The clinical data included: (1) general information of the pediatric patients such as age, gender, height and body weight; (2) preoperative data such as left ventricular ejection fraction, pediatric end-stage liver disease score, serum aminotransferase, aspartate aminotransferase, total bilirubin, International Normalised Ratio and creatinine concentrations, and whole blood Hb concentration; (3) intraoperative data such as vital signs and blood gas analysis parameters immediate before reperfusion, time of anhepatic phase, donor liver cold ischemia time, transplanted liver quality, time of surgery, anesthesia time, volume of urine, blood loss, amount of blood transfused, and amount of fresh frozen plasma transfused. The pediatric patients were divided into PRS group and non-PRS group according to whether intraoperative PRS occurred. Risk factors for PRS were analyzed using binary logistic regression analysis.Results:A total of 304 pediatric patients were finally enrolled, with 132 cases in PRS group and 172 cases in non-PRS group. The incidence of PRS was 43.4%. The results of logistic regression analysis showed that prolonged liver graft cold ischemic time ( OR=1.031, 95% confidence interval 1.021-1.042, P<0.001) and body temperature <36 ℃ immediately before reperfusion ( OR=3.095, 95% confidence interval 1.656-5.785, P<0.001) were risk factors for PRS. Conclusions:Body temperature immediately before reperfusion<36.0 ℃ and prolonged liver graft cold ischemic time are risk factors for PRS during living donor liver transplantation in pediatric patients with biliary atresia.
RESUMEN
Objective:To compare the effects of different anesthesia methods on perioperative lung injury in pediatric patients with biliary atresia undergoing living donor liver transplantation.Methods:Ninety-one American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ pediatric patients with biliary atresia, regardless of gender, aged 0-36 months, with cardiac function grade of Ⅰ or Ⅱ and Child-Pugh grade of B or C, undergoing elective living donor liver transplantation, were selected. According to the anesthesia method, the pediatric patients were divided into 3 groups: propofol-based anesthesia group (P group, n=30), sevoflurane-based anesthesia group (S group, n=30) and propofol-sevoflurane-based anesthesia group (PS group, n=31). Group P received intravenous infusion of 1% propofol 9-15 mg·kg -1·h -1. In group S, sevoflurane was inhaled and the end-tidal concentration was maintained at 2.6%-4.0%.In PS group, 1% propofol 9-15 mg·kg -1·h -1 was intravenously infused and sevoflurane was inhaled, maintaining an end-tidal concentration at 1.0%-2.5%. Remifentanil 0.1-1.0 μg·kg -1·min -1 was intravenously infused during operation for analgesia, and cisatracurium besylate 1-2 μg·kg -1·min -1 was intravenously infused to maintain muscle relaxation in three groups. Immediately after anesthesia induction (T 0), at 60 min after start of surgery (T 1), at 10 min of anhepatic phase (T 2), at 60 min after portal vein opening (T 3), and immediately after abdominal closure (T 4), the concentrations of serum Clara cell secretory protein 16 (CC16), surfactant protein (SP-D), soluble receptors for advanced glycation end products (s-RAGE), high mobility group protein B1 (HMGB1), tumor necrosis factor-alpha (TNF-α) and interleukin-1beta (IL-1β) were measured using enzyme-linked immunosorbent assay method, and lung compliance (Cdyn) was simultaneously recorded. At T 0-T 4 and 24 h after surgery (T 5), the arterial blood gas analysis was performed to calculate the oxygenation index (OI) and respiratory index (RI). Lung ultrasound scores (LUS scores) were assessed at 24 h before surgery and T 5. The occurrence of pulmonary complications was recorded within 7 days after surgery. The survival was observed for 6 months after surgery. Results:There were no statistically significant differences in serum concentrations of CC16, SP-D and s-RAGE concentrations and LUS scores at different time points between group S and group P ( P>0.05). Compared with S group and P group, the serum CC16 concentrations at T 3 and s-RAGE concentrations at T 3, 4 were significantly decreased, and the C and B scores were decreased at T 5 in PS group ( P<0.05). There were no statistically significant differences in the concentrations of serum HMGB1, IL-1β and TNF-α, Cydn and incidence of ALI/ARDS, pulmonary infection, pleural effusion, and atelectasis within 7 days after surgery among the three groups( P>0.05). The 6-month survival rate was 100% in the three groups. Conclusions:Propofol-sevoflurane-based anesthesia has a better efficacy in reducing perioperative lung injury than propofol-based anesthesia and sevoflurane-based anesthesia in the perioperative period of liver transplantation.
RESUMEN
Objective:To explore the predictive value of psoas muscle index(PMI)on early survival and complications after liver transplantation(LT)in children with biliary atresia(BA).Methods:Between January 1, 2016 and September 30, 2020, the relevant clinical data are retrospectively reviewed for 244 BA children undergoing LT at Department of Pediatric Liver Transplantation, Tianjin First Central Hospital.Total psoas muscle area(PMA)at the level of the third lumbar endplate is measured based upon preoperative abdominal computed tomography(CT)and normalized by the square of length for obtaining the value of PMI.According to the survival at Year 1 post-LT, receiver operating characteristic(ROC)curve is plotted and the cut-off value calculated.According to the cut-off value, they are divided into two groups of high PMI(173 cases)and low PMI(71 cases). Then the clinical data of 2 groups are compared.Kaplan-Meier survival curves at Year 1 post-LT are analyzed.And Cox proportional hazard model is utilized for conducting a multivariate analysis of early death.Results:The cut-off value of PMI is 534.6 mm 2/m 2.Two groups are compared in terms of age, gender, weight-for-age Z-score(WAZ), length-for-age Z-score(LAZ)and preoperative laboratory parameters ( P>0.05). Significant inter-group differences existed in the types of donors and surgery( P<0.05), and the median age of recipients in low PMI is higher than high PMI group(7.77months vs 6.57 months, P<0.01). The proportion of children with a history of Kasai surgery in low PMI group(78.87% vs 53.76%, P<0.01)and the median length of stay in hospital(23 d vs 20 d, P=0.03)is higher in low PMI group, but recipients(88.7% vs 97.1%, P<0.01)and grafts(87.3% vs 96%, P=0.01)1-year survival rate are lower.Multivariate analysis indicated that high PMI is a protective factor for early postoperative survival( HR=0.132, 95% CI: 0.028~0.626, P=0.011). Conclusions:PMI is an independent predictor of early survival post-LT and has a certain predictive value for early graft loss in BA children.
RESUMEN
@#Abstract: By report a case in which the main symptom was cholestasis in an infant and the diagnosis of Alagille syndrome (ALGS) was made after a tortuous treatment process, so as to provide clinicians with experience in diagnosing this type of patient. The patient was a 1-year and 11-month-old male who was admitted to the hospital with "abnormal liver function found for more than 1 year". Physical examination showed a wide forehead, sunken eye sockets, wide eye spacing, a sharp chin, and a grade II systolic murmur in the pulmonary valve region. Biochemical findings showed abnormal liver function accompanied by significant elevation of total bile acids and γ-glutamyl transpeptidase. CT scan of the thoracic vertebrae showed sagittal vertebral fractures in the thoracic 3-7 vertebrae, and pulmonary arteriography showed pulmonary stenosis and genetic testing indicated a JAG1 mutation. Combining the patient's specific facial features, heart defects, spinal deformities, and bile stasis clinical symptoms, along with the genetic analysis results, the final diagnosis was confirmed as Alagille syndrome. Alagille syndrome is the most common cause of chronic cholestasis with phenotypic features and is a dominant inherited disease involving multiple systems. Most patients present with bile stasis as the main symptom within the first three months after birth. Alagille syndrome needs to be distinguished from various forms of cholestasis in infancy, and since biliary atresia requires early surgical treatment, most children with cholestasis as the main clinical manifestation are considered to have biliary atresia at an early stage and undergo a caesarean section. If Alagille syndrome is misdiagnosed as biliary atresia, and surgery may worsen the prognosis. Therefore, the biggest challenge in the early diagnosis of Alagille syndrome is how to distinguish it from biliary atresia. Therefore, physicians need to improve their knowledge of rare cholestatic liver disease in clinical practice to accurately identify rare cholestatic liver disease in the early stages of the disease, and improve improve their diagnosis and treatment levels.
RESUMEN
Objetivo: El objetivo de este estudio fue valorar el nivel de acierto del personal de salud en la identificación de hipocolia/acolia en un escenario simulado. Con respecto a esto afirmamos que la hipocolia/acolia son signos clínicos que indican obstrucción biliar, relacionándose con enfermedades colestásicas obstructivas, siendo la atresia de vías biliares una de las principales causas en los primeros meses de vida; en esta, el pronóstico del manejo quirúrgico depende del diagnóstico temprano. Métodos: Estudio descriptivo/ prospectivo basado en la realización de una prueba virtual al personal de salud de Medellín, dividiéndose según sitio de trabajo, edad, sexo y profesión. Fueron utilizadas cinco imágenes de la tabla de colores de materia fecal, utilizada en Taiwán, previa autorización de sus autores. Se consideró reconocimiento adecuado cuando el participante identificaba como anormales las tres imágenes que representaban la acolia/hipocolia. Resultados: Se obtuvo respuesta de 442 participantes (se excluyeron 53) y solo 253 (65 %) lograron reconocimiento adecuado. En el análisis por subgrupos se encontró que hubo un mayor acierto en los participantes del Hospital Pablo Tobón Uribe con respecto a otras instituciones (69 y 54.6 %, respectivamente - p. 0.005). Los participantes con menor porcentaje de acierto fueron los médicos generales en un (45 %). Conclusión: Durante la valoración simulada sobre la identificación adecuada de acolia/hipocolia se encontró que solo el 65 % de la población participante acertó en la identificación correcta de este signo clínico, lo que sugiere una mayor atención en cuanto al entrenamiento para la identificación de acolia/hipocolia.
Objetive: The objective of this study was to assess the level of success of healthcare worker in the identification of hypocholia / acholia in a simulated scenario. With respect to this, we affirm that hypocholia/acholia are clinical signs indicative of biliary obstruction, related to obstructive cholestatic diseases, being bile duct atresia one of the main causes in the first months of life. In this, the prognosis of surgical management depends on the early diagnosis. Methods: Descriptive and prospective study, based on the analysis of a virtual survey to Medellín's healthcare workers, subgroup analysis was done according to workplace, age, sex and profession. Five images were used from the Taiwan Stool Color Card, with the authorization from their authors. Adequate recognition was considered when the participant identified the three images representing acholia / hypocholia as abnormal. Results: a response was obtained from 442 participants (53 were excluded), and only 253 (65 %) achieved adequate recognition. In the analysis by subgroups, it was found that there was a greater success in the Pablo Tobón Uribe Hospital participants with respect to other institutions (69 % and 54.6 %, respectively - p. 0.005). The participants with the lowest percentage of correct answers were general practitioners (45%). Conclusion: During the simulated assessment on the adequate identification of acholia / hypocolia, it was found that only 65% of the participating population was correct in the right identification of this clinical sign, which suggests greater attention in training for the identification of acholia / hypocolia.
RESUMEN
Abstract Background: Left isomerism (LI) is a common finding in patients with biliary atresia (BA), and it can be identified by echocardiography. Several comorbidities may be present in patients with LI, including heart disease. Objective: To investigate the prevalence of LI and heart disease in children (< 18 years of age) with BA followed-up at Hospital das Clínicas, UFMG. Methods: This is a cross-sectional study involving patients diagnosed with BA between February 2016 and April 2020 who underwent transthoracic echocardiography and, in case of situs abnormalities, also electrocardiography. Results: Our study recruited 58 patients (mean age: 3.08 years; female/male ratio: 1.5:1). The general prevalence of situs abnormalities was 8.6% (5/58) and the most common one was LI (4/5 or 80%). One patient had situs inversus. Among patients with situs abnormalities, the general prevalence of heart disease was 80% (4/5), apart from anomalies of the inferior vena cava), with pulmonary valve stenosis (PVS) as the only change seen (75% of mild forms and 25% of moderate forms). Among patients with situs abnormalities, the prevalence of rhythm changes was 80% (4/5), and low atrial rhythm was the most common finding (3/4 or 75%). Conclusion: The prevalence of situs abnormalities in our sample was similar to that described in the literature. We observed an exclusive prevalence of PVS and a high prevalence of rhythm changes among patients with LI. Although the diagnosis of isomerism does not initially add much cardiovascular risk to the sample, possible late deterioration should be considered.
