??Objective??To analyze the influence of perinatal period factors??feeding strategies??probiotics usage??complications and mechanical ventilation before the onset of the disease on neonatal necrotizing enterocolitis??NEC????in order to explore the risk factors for NEC. Methods??Totally 76 infants with NEC were classified as the case group??who were hospitalized in the First Neonatal Department of Shengjing Hospital of China Medical University from January 2011 to January 2016??80 infants without NEC who were admitted at the same time were randomly selected as the control group. A retrospective analysis was performed on the clinical data of these patients??including general conditions of newborns??perinatal period factors??feeding strategies??probiotics usage??complications and mechanical ventilation before the development of NEC. Single and multiple factor analysis was performed on 19 items using the SPSS analysis software. Results??Single factor analysis revealed that the incidence of asphyxia??sepsis??hypoglycemia and mechanical ventilation was higher??while the incidence of oral probiotics usage was lower in the case group than the control group??with statistically significant difference??P??0.05??. According to the logistic multivariate regression analysis??sepsis??OR??6.531????hypoglycemia??OR??2.785?? and mechanical ventilation??OR??3.448?? were risk factors of NEC??while oral probiotics usage was protective factor of NEC??OR??0.417??. Conclusion??Sepsis??hypoglycemia and mechanical ventilation are risk factors of NEC??and oral probiotics usage is protective factor of NEC. We should pay attention to the prevention and intervention of NEC by reasonably analyzing these factors??in order to improve the prognosis of these children. 相似文献

??Abstract?? Allergic disorders and rheumatic diseases are two common diseases of dysregulated immune system in children?? with the feature of long disease course and easy relapse??and the incidence of the two diseases is increasing. All these features are bad for the prognosis of children with the diseases. Prior Th1/Th2 theory deemed that Th1-mediated autoimmune diseases and Th2-mediated allergic conditions are complementary both on the mechanism and incidence?? which improve patients’ outcomes with a new balance of T cell subsets. Recent studies?? however?? have served to challenge the idea that the presence of allergy and autoimmunity are mutually exclusive states and suggest that allergic diseases and rheumatic diseases are risk factors for each other. Clear understanding of the relationship between children’s rheumatic diseases and allergic disorders will have important implications for clinical treatment and diagnosis. This article clarifies the influence of allergic diseases on children’s rheumatic disease. 相似文献

??Children often visit their general practitioner for treatment of chronic cough. Recently?? pediatricians have paid more attention to protracted bacterial bronchitis??PBB?? as it is one of the most common causes of chronic wet cough in children. PBB is associated with persistent or protracted bacterial infection of the conducting airways. Clinical diagnosis is very important. Haemophilus influenzae?? especially non-typable H. influenza strains?? streptococcus pneumoniae and moraxella catarrhalis are the three most commonly identified bacteria. The occurrence of PBB is related to bacterial biofilm formation in the airway??impaired mucociliary clearance??systemic immune function defects??and airway anomalies. The common symptoms of PBB include wet cough??wheezing??and stridor. Pulmonary signs are moist rales and/or wheezing. The current international clinical guidelines recommend antibiotic treatment as appropriate management for PBB. A two-week amoxicillin/clavulanate regimen will achieve cough relief in a significant number of children with PBB. 相似文献

Miloh T, Kerkar N, Parkar S, Emre S, Annunziato R, Mendez C, Arnon R, Suchy F, Rodriguez‐Laiz G, Del Rio Martin J, Sturdevant M, Iyer K. Improved outcomes in pediatric liver transplantation for acute liver failure.Pediatr Transplantation 2010: 14:863–869. © 2010 John Wiley & Sons A/S. Abstract: OLT is a life‐saving option for ALF. Aim: To evaluate our outcomes in pediatric OLT for ALF. Methods: Retrospective review of our data between 1992 and 2007. Results: Of 142 children with ALF, 126 were listed, of which 40 spontaneously improved, nine died, and 77 underwent OLT (median waiting time four days). Fifty‐three children received deceased donor grafts (34 whole and 19 split grafts), and there were 24 living donor grafts. The one‐ and five‐yr patient survival was 87% and 80%, and graft survival 83% and 79%, respectively. Thirteen patients died after OLT, and there were nine retransplants in seven patients. Patient weight, length of stay, creatinine, and infection were significantly associated with death; increased weight and black ethnicity were associated with graft loss on univariate analysis, but not on multivariate analysis. There were no significant differences in patient survival (one and five yr), graft loss, or other complications between the groups. Conclusion: We report the largest single‐center study of OLT in pediatric ALF, demonstrating no difference in outcomes between different graft types. Our liberal use of segmental grafts may allow earlier OLT in this high‐risk cohort and contribute to our excellent outcomes. 相似文献

??The true incidence of fulminant hepatic failure in the pediatric population is unknown?? though fulminant hepatic failure is a rare but devastating syndrome??such as hepatic encephalopathy??DIC??MODS?? that results in the death of most children affected. The mainstay of the treatment is liver transplantation??however?? organ shortage limits its use.The purpose of this review is to introduce the current situation of fulminant liver failure in children??focusing on assessing the application of artificial liver??which is considered to play a pivotal role in the treatment of fulminant liver failure.According to its classification??we mainly discussed the application of non-biological artificial liver?? including its indications??advantages and disadvantages??especially the MARS. At present?? the artificial liver treatment also faces many problems.

The orthotopic liver transplantation (OLT) allows survival of children followed for severe hepatic injury, provided that the immunosuppressive treatment is prolonged. The nephrotoxicity of cyclosporine predicts the long-term outcome of the adult patients receiving a liver transplant. The aim of this study was to determine the long-term outcome of renal function in children receiving OLT. This study included 12 children, with a median for age of 7.1 yr (2-15 yr) at the time of OLT. The duration of follow-up was at least 4 yr, being 7 yr in 10 patients and more than 10 yr in seven. Renal function was evaluated with the serum level of creatinine, calculated glomerular filtration rate (cGFR), and measurement of glomerular filtration rate using chrome 51 ethylenediaminetetraacetate ((51)Cr EDTA) clearance performed at least once during follow-up. The doses and the serum concentrations (C(0)) of cyclosporine were reported at each study time. The cGFR decreased significantly 2 yr after the OLT [median (range): 106 mL/min/1.73 m(2) (71-150) at the time of OLT vs. 85 mL/min/1.73 m(2) (57-128) 2 yr after the OLT, p = 0.03], and decreased again between 7 and 10 yr after OLT [median (range): 99 mL/min/1.73 m(2) (76-125) 7 yr after OLT vs. 81 mL/min/1.73 m(2) (66-140) 10 yr after OLT, p = 0.04]. Six patients developed chronic renal failure (cGFR from 57 to 80 mL/min/1.73 m(2)) 2 yr after OLT associated with high doses of cyclosporine [median (range): 8.8 mg/kg/day (3.5-13)]. The cGFR overestimated renal function by 16% compared with the isotopic measurement of GFR (p = 0.03). Using the (51)Cr EDTA measurement, six of seven patients followed up more than 10 yr after OLT presented mild (n = 3) or moderate (n = 3) chronic renal failure. In our study, the majority of OLT recipients developed a chronic renal failure 10 yr after transplantation. Cyclosporine seems to be the most important factor responsible for the impairment of renal function. The use of the mycophenolate mofetil, a new immunosuppressive agent, allowing a reduction in the dose of cyclosporine, could minimize renal dysfunction. While awaiting the results of a prospective long-term study, close drug monitoring is advised. 相似文献

Abstract: ALF is a serious, often fatal condition. Up to half of PALF patients do not survive without liver transplantation; however, early identification of those least likely to survive spontaneously remains difficult. Clinical experience suggests that recovery from ALF depends on the ability of the liver to regenerate. Based on this, we hypothesized that bio-markers of hepatic regeneration could have utility as predictors of recovery from PALF. In the studies reported here, we used comprehensive amino acid analysis to search for novel metabolomic markers of liver regeneration in mice subjected to partial hepatectomy. This analysis identified α-NH2 -adipic acid and α-NH2 -butyric acid as significantly increased in liver and plasma samples from mice subjected to partial hepatectomy compared to controls. Next, we tested whether serum levels of these markers were associated with clinical outcomes in PALF patients. This examination, performed on the initially collected serum samples from 40 randomly selected patients enrolled in the PALF Study Group, showed increased α-NH2 -butyric-acid (Aab) and Aab:leucine (Aab:Leu) ratio in patients who survived without transplantation compared to those who were transplanted or died. These data indicate that Aab and the Aab:Leu ratio may predict clinical outcomes in PALF. 相似文献

??The causes of acute liver failure ??ALF?? in children differ from those observed in adults. They can be schematically grouped into six categories?? metabolic?? infective?? toxic?? autoimmune?? vascular and malignancy-induced ALF. Although the mechanisms of liver injury contributing to ALF vary due to different causes and are incompletely understood?? they can be summarized into two categories?? direct damage and immune-mediated liver injury. Cellular necrosis and apoptosis are the final changes of pathology. This article will review the current knowledge of the epidemiology and mechanisms of ALF in children. 相似文献

Lymphoma is a recognized cause of liver damage and in rare instances presents as ALF. In such cases, the underlying malignancy is often difficult to detect. Historically, the prognosis has been poor. Cure has occasionally been achieved with chemotherapy alone. LT in this setting is controversial, but has contributed to successful outcomes, as in the case of the five-yr-old girl reported here. 相似文献

Abstract: ALF is characterized by sudden onset, impaired liver function, jaundice and encephalopathy, without previous liver disease. We analyzed the patients who underwent LT due to toxic agent induced ALF to raise community awareness about preventing the toxic agent induced ALF. Five children (three boys, two girls) underwent LT due to toxic agent ingestion. Toxic agents were mushroom poisoning (n = 2), Datura stramonium (n = 1), yellow phosphorous (n = 1) and INH (n = 1). On admission, one patient had stage IV, two had stage III and two had stage II hepatic encephalopathy but worsened during the follow‐up. One patient had renal failure, and three patients required mechanical ventilation. Three patients underwent LRLT and others from a DD. Post‐operative complications were managed by supportive managements successfully, and overall all the patients are alive (100% survival) without any organ sequelae. Although outcome of these patients are excellent, ALF may be prevented in these cases by educating the public about consuming mushrooms and toxic effects of wild plants, prohibiting fireworks and serial liver enzyme measurements after initiating INH. 相似文献

Hypogammaglobulinemia has been reported after solid organ transplantation in adults, however immunoglobulin replacement [intravenous immunoglobulins (IVIG)] is only necessary in a minority of affected patients. We here present three pediatric patients with severe post-transplant hypogammaglobulinemia following liver transplantation (LTx) receiving a cyclosporine-based standard immunosuppression. Patient 1 was transplanted at the age of 10 months for biliary atresia. Eight weeks post-Ltx the serum IgG was 1.7 g/L. Patient 2 was transplanted at the age of 12 yr for acute liver failure. Four weeks post-Ltx the IgG dropped to 2.6 g/L. Patient 3 was transplanted at the age of 4 months for biliary atresia. Ten weeks post-Ltx severe hypogammaglobulinemia (IgG < 1.48 g/L) was diagnosed during a severe infectious complication. Patients 1 and 3 received a steroid bolus therapy for acute graft rejection. All patients had normal IgG concentrations prior to Ltx and lymphocyte subsets were post-operatively in the normal range. There was no extensive loss of protein by ascites. IGIV were replaced in the three patients monthly without further complications. In two of the patients (1 and 3) IVIG therapy was discontinued 8 and 10 months after Ltx when the immunosuppression has been reduced and serum IgG concentrations were found in the normal range without further immunoglobulin replacement. Severe hypogammaglobulinemia is a rare phenomenon following pediatric LTx and seems to be mainly caused by immunosuppressive drugs, however, the exact underlying mechanisms are unclear. A screening for hypogammaglobulinemia is useful after pediatric LTx, especially in patients with an intensified immunosuppression. Moreover, further immunologic research in affected patients is necessary. 相似文献
