RESUMEN
Objective:To analyze the early risk warning factors of clinical characteristics in children with acute lymphoblastic leukemia (ALL) complicated with acute pancreatitis (AP).Methods:Retrospective study.A total of 39 children with ALL complicated with AP admitted to the Hematology Center of Beijing Children′s Hospital, Capi-tal Medical University from May 2018 to December 2020 were selected as the case group, and 78 ALL patients were randomly selected as the control group according to the exact matching of 1∶2 of the same age and sex.The measurment data and counting data were analyzed by Rank sum test ( Mann Whitney U test) and χ2 test between the 2 groups, respectively, and further multivariate Logistic regression analysis was performed to find out the risk factors of ALL complicated with pancreatitis.At the same time, the relationship between each index and severity was explored. Results:The incidence of ALL complicated with AP was 8.55% (39/456 cases). The high incidence age was 3-10 years old.Sixty-four point nine percent (24/37 cases) of the pancreatitis occurred in the early stage of chemotherapy, and 66.7% (26/39 cases) was associated with asparaginase.There were significant differences in ALL risk stratification ( χ2=21.404, P<0.001), C-reactive protein (CRP)( U=232.000, P<0.001), procalcitonin (PCT)( t=3.950, P<0.001), hematocrit( t=3.981, P<0.001), serum calcium( t=-9.609, P<0.001), indirect bilirubin( U=1 142.000, P<0.05), triglyceride( t=3.600, P=0.001) and albumin( t=-6.296, P<0.001) between the 2 groups.The sensitivity of abdominal CT, abdominal ultrasound and pancreatic magnetic resonance imaging in the case group were 70.8%, 81.6% and 100.0%, respectively.Multivariate Logistic regression analysis showed that differences between albumin( OR=11.444, 95% CI: 3.240-40.423), triglyceride( OR=18.047, 95% CI: 5.020-65.074) and risk stra-tification( OR=8.894, 95% CI: 1.889-41.885) were statistically significant, and there were obvious differences in PCT( U=3.000, 2.000, all P<0.05) and serum calcium( U=4.500, 8.500, all P<0.05) between patients with severe pancreatitis and patients with mild or moderate severe pancreatitis. Conclusions:ALL complicated with AP often occurs in the early stage of chemotherapy, mainly caused by asparaginase.In imaging examination, the sensitivity of pancreatic magnetic resonance imaging is the highest, followed by abdominal ultrasound.Risk stratification, decreased albumin and elevated triglyceride are risk factors of ALL complicated with AP, which are helpful for early identification of high-risk patients with ALL complicated with AP.PCT and serum calcium may play an important role in severe pancreatitis.
RESUMEN
Objective:To evaluate the value of sugammadex for ultra-fast-track anesthesia in pediatric patients undergoing surgery for correction of congenital heart disease.Methods:Forty pediatric patients of both sexes, aged 1-6 yr, with American Society of Anesthesiologists physical status Ⅱ, scheduled for elective surgery for correction of congenital heart disease, were enrolled in this study and randomly assigned into sugammadex group (group S) and control group (group C) with a random number table.Sugammadex 4.0 mg/kg was injected intravenously to reverse neuromuscular relaxation in group S and the equal volume of normal saline was administrated in group C when the train-of-four (TOF) count was 0 and post-tetanic count was 1 or 2 during recovery from anesthesia.The recovery time of TOF ratio to 25%, 75% and 90%, the extubation time and the success rate of ultra-fast-track anesthesia were recorded.Results:Compared to group C, sugammadex significantly shortened the recovery time of TOF ratio to 25%, 75% and 90% and the extubation time in group S ( P<0.05); Furthermore, the success rate of ultra-fast-track anesthesia reached 100% in group S compared to 0% in group C. Conclusion:Intravenous administration of sugammadex 4.0 mg/kg significantly shortens the recovery time of neuromuscular relaxation and extubation time and enhances the success rate of ultra-fast-track anesthesia in pediatric patients undergoing surgical correction of congenital heart disease.
RESUMEN
Objective:To have a better understanding of congenital leukemia by summarizing its clinical features and prognosis.Methods:This study retrospectively recruited 10 neonates with congenital leukemia treated in Beijing Children's Hospital, Capital Medical University from January 2006 to December 2018. Clinical data including clinical manifestations, laboratory examinations, treatment and follow-up were described.Results:The 10 patients consisted of six boys and four girls. In all cases, symptoms presented within 11 d after birth. The admission complaints were jaundice ( n=4), polypnea ( n=3), fever ( n=2) and rash ( n=2). Physical examinations of the 10 patients showed eight with splenomegaly, seven with hepatomegaly and seven with petechia/skin rash. All patients had significantly increased white blood cell count (from 45.8×10 9/L to 553.0×10 9/L), complicated by different degrees of anemia and thrombocytopenia. By bone marrow biopsy, two cases were diagnosed as acute lymphoblastic leukemia and the other eight cases as acute myeloid leukemia. All cases refused chemotherapy on the preliminary diagnosis. Three cases lost follow-up and six died within two months after discharge requested by their parents. One baby had spontaneous remission, but relapsed two years later. Complete remission was achieved after strict management and no relapse was reported until ten years old. Conclusions:Congenital leukemia is a severe condition with high mortality. Some cases may achieve spontaneous remission, but long-term follow-up is needed.
RESUMEN
Objective To investigate the efficacy of blood purification for acute lymphoblastic leukemia pediatric patients with high-dose methotrexate (MTX)-induced hypermethotrexemia and acute kidney injury (AKI). Methods The clinical data of 50 acute lymphoblastic leukemia pediatric patients with hypermethotrexemia (the 45th hour MTX blood concentration ＞20 μmol/L) and AKI who were admitted to Beijing Children's Hospital Capital Medical University from May 2010 to August 2018 were collected. After the treatment of blood purification, the declining rate of MTX concentration, the incidence of drug-related side effects and the clinical transition were analyzed retrospectively. Results The median MTX blood concentration at the 45th hour after high-dose MTX chemotherapy was 31.5 μmol/L (20.0-80.3 μmol/L). After blood purification treatment, 48 patients (96%) survived, 1 patient (2%) died, and 1 patient (2%) gave up treatment. It costed 10.0 days (7.0-15.0 days) to decline the MTX concentration to the normal level by using blood purification. The median time of purification was 32.5 hours (2.0-168.0 hours), and the days of dialysis were 3.0 days (1.0-9.0 days). The AKI occurred in approximately 96% (48/50) of patients, which was the main side effect. The time of declining the high MTX concentration to the normal was positively correlated with the increase times of serum creatinine (r ＝ 0.371, P＝ 0.009) and urea nitrogen (r ＝ 0.486, P＝ 0.001), and the value of the alanine aminotransferase (r ＝0.364, P＝0.010) and gamma glutamyl transpeptidase (r ＝ 0.344, P＝ 0.010), and the days of dialysis (r ＝ 0.532, P < 0.01), but there was no relationship with the 45th hour MTX blood concentration (r＝0.110, P＝0.248). The reduction of MTX blood concentration from the 45th hour to the 69th hour after high-dose MTX chemotherapy was negatively correlated with the increase times of urea nitrogen (r ＝ -0.336, P＝ 0.009) and serum creatinine (r ＝ -0.260, P＝ 0.035). Conclusion When the MTX blood concentration of patients with hypermethotrexemia and AKI couldn't be declined to the normal level by using high-dose leucovorin, hydration and alkalization, and without the effective detoxification drug (carboxypeptidase G2), they should be offered blood purification, especially continuous renal replacement therapy as soon as possible, which can reduce the blood concentration of MTX quickly and decrease the incidence of side effects effectively.
RESUMEN
OBJECTIVE@#To evaluate the efficacy of volume therapy with sodium acetate Ringer solution during the perioperative period in children with cyanotic congenital heart disease (CHD).@*METHODS@#The children who underwent elective surgery for cyanotic CHD admitted to Shanghai Children's Medical Center Affiliated to the Medical School of Shanghai Jiaotong University from September to December 2018 were divided into three groups according to random number table with the informed consent of their legal representatives. All of the children received volume therapy with infusion of sodium acetate Ringer solution intravenously upon anesthesia induction. The volume of infusion was calculated according to the "4-2-1" formula (group A, the rehydration volume was 4 mL×kg-1×h-1 for the first 10 kg body weight, 2 mL×kg-1×h-1 for the second 10 kg, and 1 mL×kg-1×h-1 for the third 10 kg and above), and the volume was increased by 50% or 100% in groups B and C, respectively. The intravenous infusion lasted for 30 minutes in all the three groups. Arterial blood gas analysis was performed before and 30 minutes after infusion to observe the acid-base status and electrolyte level. Pulse oxygen saturation (SpO2), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) before and 10, 20, 30 minutes after infusion, central venous pressure (CVP) at 30 minutes after infusion were recorded, as well as adverse events occurred after infusion.@*RESULTS@#Twenty-six children with cyanotic CHD, 17 male and 9 female, aged from 1 to 36 months, body weight 3.6 to 16.0 kg, and America Society of Anesthesiologists (ASA) level of III or IV, were enrolled in the study. The pH value in group B at 30 minutes after infusion was significantly higher than that before infusion (7.35±0.05 vs. 7.32±0.06, P < 0.05), while no significant changes were found before and after infusion in the other two groups. The hematocrits (Hct) after infusion in three groups were significantly lower than those before infusion (0.433±0.141 vs. 0.473±0.146 in group A, 0.324±0.054 vs. 0.372±0.063 in group B, 0.363±0.097 vs. 0.418±0.111 in group C, all P < 0.01), indicating that all the children in the three groups achieved effective hemodilution. However, there was no significant difference in blood gas analysis before and after infusion among the three groups. The level of blood lactic acid (Lac) in all CHD children was decreased from (1.33±0.63) mmol/L to (0.98±0.36) mmol/L after infusion of sodium acetate Ringer solution, the serum Ca2+ concentration was decreased from (1.22±0.06) mmol/L to (1.19±0.06) mmol/L, and the serum Cl- concentration was increased from (108.74±2.70) mmol/L to (109.77±2.54) mmol/L with the statistically significant differences (all P < 0.01). However, no significant difference was found in Lac or electrolyte levels before and after infusion among the three groups. There was no significant difference in vital signs before and after infusion among the three groups, but the period of infusion had an effect on SpO2 (F = 5.998, P < 0.01), HR (F = 34.279, P < 0.01) and SBP (F = 4.345, P < 0.05). HR in groups A and C were significantly lower than those before infusion, and SBP in group A was decreased gradually with the prolongation of infusion time. The CVP value at 30 minutes after infusion in group B was higher than that in group A. No adverse reactions such as rash or anaphylactic shock occurred after infusion of sodium acetate Ringer solution in all children.@*CONCLUSIONS@#The perioperative volume therapy with sodium acetate Ringer solution in children with cyanotic CHD can effectively prevent the increase in Lac level and does not aggravate metabolic acidosis. The volume of infusion was well tolerated by all the children without disturbing the hemodynamic parameters.

Objective@#To observe the changes in nutrition indicators and the effect on chemotherapy complications as well as the safety of enteral nutrition by way of providing enteral nutrition support for children with acute lymphoblastic leukemia (ALL) at the stage of induction chemotherapy.@*Methods@#From November 2016 to September 2017, 60 children with newly diagnosed ALL at the Hematology Oncology Center of Beijing Children′s Hospital were enrolled in this study.They were randomly divided into an experimental group and a control group, 30 cases for each group.The experimental group was given a high-calorie diet, high-quality protein, and high-medium-chain trigly-ceride enteral nutrition on the basis of a conventional low-fat diet, and the duration lasted the whole induction treatment of ALL children; while the control group was given a low-fat diet routinely.By analyzing relevant indicators before induction chemotherapy (D0), chemotherapy day 15 (D15), and after chemotherapy (D33), the changes in nutritional status and the effect on chemotherapy complications in 2 groups were investigated.@*Results@#There was no significant difference in the body mass index (BMI) and the thickness of triceps skinfold between 2 groups before and after chemotherapy (all P>0.05). The upper arm circumference increased after chemotherapy in the experimental group[before treatment: (15.80±2.63) cm, after treatment: (16.27±2.57) cm], while that of the control group decreased slightly[before chemotherapy: (17.19±3.71) cm, after chemotherapy: (17.15±3.64) cm], and the difference between 2 groups was statistically significant (P<0.05). After chemotherapy, the total protein levels in two groups decreased[the experimental group: (64.52±4.85) g/L, the control group: (61.97±4.65) g/L] which was significantly different from that before chemotherapy [the experimental group: (68.17±6.37) g/L, the control group: (68.08±5.14) g/L] (P<0.01). The total protein level of the experimental group after chemotherapy was significant higher than that in the control group (P<0.05). Both albumin levels in 2 groups increased after chemotherapy [(42.45±4.32) g/L in the experimental group and (41.15±3.73) g/L in the control group], and there was a significant difference between 2 groups before chemotherapy [(39.54±3.26) g/L in the experimental group and (40.01±4.37) g/L in the control group] (P<0.05). The level of prealbumin increased after chemotherapy in both groups [(324.57±64.328) mg/L in the experimental group and (293.07±69.09) mg/L in the control group] compared with that before chemotherapy [(121.10±35.13) mg/L in the experimental group and(131.20±52.77) mg/L in the control group]. The change was statistically significant (P<0.01). The albumin level in the experimental group before chemotherapy was lower than that in the control group after chemotherapy, but it was higher than that in the control group after chemotherapy.Protein differences were statistically significant (P<0.05). The reduction rate of elemental iron in the experimental group after chemotherapy was lower than that in the control group, but it was not statistically significant (P>0.05). Elemental zinc was not significantly different compared with the control group.The incidence of neutropenia after chemotherapy in ALL children was higher (37/60 cases, 61.67%). The recovery of neutropenia after chemotherapy in the experimental group was better than that in the control group.After chemotherapy, the severity of anemia in the experimental group was lighter than that in the control group.The amount of blood transfusion required and amount of transfusion per capita were less than those in the control group (54 person-times vs.74 person-times, 2.45 times vs.3.08 times). The total number of transfused blood products was less than that of the control group (78 person-times vs.101 person-times), but none of the findings above were statistically significant (all P>0.05). The degree of hepatic damage in the experimental group decreased after chemotherapy, but there was no significant change in the control group.The initial activated partial thromboplastin time(APTT) prolongation in the trial group was more than that in the control group (5 cases vs.3 cases), and less than the control group (0 case vs.1 case) after chemotherapy.The frequency of fever in the experimental group during chemotherapy was less than that in the control group (6 cases vs.8 cases), and the average time of fever was shorter than that in the control group (2.8 d vs.4.1 d). None of the above findings were statistically significant (all P>0.05). During the course of chemotherapy, 0 pancreatitis occurred in the experimental group, and 1 pancreatitis occurred in the control group.There was no difference in remission rates between 2 groups of chemotherapy for 15 days and chemotherapy for 33 days.@*Conclusions@#The nutritional status of children with ALL was reduced after initial induction chemotherapy.Enteral nutrition support was helpful to maintain the nutritional status for children at the initial stage of chemotherapy, high-calorie diet, high-quality protein, and high-medium-chain triglyceride enteral nutrition support improves blood system tolerance to chemotherapy and reduces chemotherapy complications.

The CVP value at 30 minutes after infusion in group B was higher than that in group A. No adverse reactions such as rash or anaphylactic shock occurred after infusion of sodium acetate Ringer solution in all children. Conclusions The perioperative volume therapy with sodium acetate Ringer solution in children with cyanotic CHD can effectively prevent the increase in Lac level and does not aggravate metabolic acidosis. The volume of infusion was well tolerated by all the children without disturbing the hemodynamic parameters.

Objective@#To investigate the current status of catheter-related-thrombosis (CRT) and the risk factors of Chinese acute lymphocytic leukemia (ALL) children with peripherally inserted central catheter (PICC) .@*Methods@#The clinical data of the 116 inpatients preliminarily diagnosed ALL in the Leukemia Ward of Beijing Children’s Hospital with PICC from 1st March 2014 to 31st December 2014 were collected prospectively.@*Results@#①Refer to the B-ultrasound on the 15th day after catheterization, the incidence of CRT was 28.4% (33/116 cases) , all cases were symptom-free. ②There were no statistical differences in terms of gender, age distribution, degree, immunotype between CRT and CRT-free groups. This study revealed no statistical differences of blood routine test items, coagulation function items, co-infection and catheterization vein between the two groups. While there was significant statistical difference of catheterization side, the frequency of right catheterization was higher in CRT group[75.8% (25/33) vs 55.4% (46/83) , P=0.043]. ③On the 15th day after catheterization, significant statistical difference of D-Dimer between the two groups was revealed[0.18 (0.05-2.45) mg/L vs 0.11 (0.01-5.34) mg/L, P=0.001], while no statistical differences of blood routine test items and other coagulation function items. Multivariate Logistic regression analysis verified catheterization on right was a risk factor of CRT. ④During the observation, there were 3 cases of catheter-related complications other than CRT, all of which were CRI, 2 of them had CRT meanwhile. ⑤The B-ultrasound on the 33rd day after catheterization showed that 73.1% of the cases had reduced thrombosis, 3.8% had growth thrombosis, 23.1% had no obvious change respectively.@*Conclusion@#CRT was a common catheter related complication among ALL children during induction chemotherapy, and CRT cases with symptoms were rare. Catheterization on right was a risk factor for CRT, and regular test of D-Dimer and B ultrasound contributed to detect CRT. Most of the CRT cases had reduced thrombosis without specific management.
RESUMEN
Objective To analyze the effect of different methods of anesthesia maintenance on clinical efficacy and postoperative recovery in elderly patients with gynecological diseases undergoing laparoscopic surgery.Methods A total of 80 elderly patients with gynecological diseases scheduled for laparoscopic surgery were enrolled in this study in our hospital from January 2015 to December 2016.All the patients were randomly divided into two groups of anesthesia maintenance:an intravenous anesthesia alone (n=40) and a combined intravenous and inhaled anesthesia (n =40).The pre-and post-anesthesia changes in arterial blood gas,blood pressure,heart rate and cognitive function,and postoperative complications were analyzed and compared between the two groups.Results There were no significant differences between the two groups in the times of palinesthesia,extubation and talking (all P＞ 0.05).After anesthesia,the levels of arterial blood gas,the blood pressure and the heart rate were relatively stable in both groups,and their differences between the two groups were without statistically significant (all P ＞ 0.05).While,the postoperative cognitive function recovered more rapidly in patients receiving intravenous anesthesia alone for anesthesia maintenance than in those receiving a combined intravenous and inhaled anesthesia,especially at 6 h after extubation.The Mini-mental State Examination (MMSE) score was significantly higher in patients receiving intravenous anesthesia alone (28.8 ± 0.5) than in patients receiving a combined intravenous and inhaled anesthesia (25.1 ±0.6),with statistically significant difference (P＜ 0.05).In addition,there was no statistical difference between the two groups in the incidence of complications.Conclusions As anesthesia maintenance,both an intravenous anesthesia alone and a combined intravenous and inhaled anesthesia can ensure a successfully laparoscopic surgery for gynecological diseases in elderly patients.However,the impact on cognitive function after laparoscopic surgery is smaller in the maintenance of intravenous anesthesia alone than in a combined intravenous and inhaled anesthesia in elderly patients.Intravenous anesthesia alone can be used in elderly patients to receive laparoscopic surgery as routine anesthesia maintenance.
RESUMEN
Objective To evaluate the myocardial protective effect of dexmedetomidine in the pediatric patients undergoing total correction of tetralogy of Fallot.Methods Forty ASA physical status Ⅱ] or Ⅲ pediatric patients of both sexes,aged 9 months-5 yr,weighing 7-21 kg,scheduled for elective total correction of tetralogy of Fallot under cardiopulmonary bypass,were randomly divided into 2 groups (n =20 each):control group (C group) and dexmedetomidine group (D group).Anesthesia was induced with iv injection of midazolam,sufentanil,etomidate and rocuronium.The patients were endotracheally intubated and mechanically ventilated.After intubation,dexmedetomidine was infused intravenously at 0.6 μg· kg-1 · h-1 until the end of operation in group D,while the equal volume normal saline was given instead of dexmedetomidine in group C.Venous blood samples were obtained before operation,at the end of operation and at 24 h after operation for determination of plasma TNF-α and IL-6 concentrations.The occurence of anoxic spells was recorded.Results The concentrations of plasma TNF-α and IL-6 were significantly lower at the end of operation and 24 h after operation in group D than in group C(P ＜0.05).The incidence of anoxic spells was 0 in group D,however it was 20％ in group C.Conclusion For the pediatric patients undergoing total correction of tetralogy of Fallot under cardiopulmonary bypass,dexmedetomidine infused at 0.6 μg· kg-1 · h-1 during operation can exert myocardial protective effect with clinical significance.
RESUMEN
ObjectiveTo evaluate effects of post-operative analgesia combined with parental presence on emergence agitation after sevoflurane anesthesia in children. Methods60 patients were randomly assigned into three groups with 20 cases each. After sevoflurane inhalation and being given rocuronium, all patients were intubated for mechanical ventilation. Then patients received caudal block. Patiens in group A and B were treated with diclofenac sodium suppositories before operation. To maintain anesthesia patients were adopted sevoflurane inhalation. Patients in group A and C were cared by nurses in post anesthesia care unit, whereas patients in group B added parental presence. Emergence agitation incidence, modified Aldrete scale, PAEDS, CHEOPS were all recorded. ResultsTherewas no difference of modified Aldrete scale among three groups( F =0.652 ,P ＞0. 05) ,but emergence agitation incidence in group C was more than those of group A and B. At each point PAEDS scores of group B were lower than those of group C( x2 =4. 566,7. 234,4. 124,6. 126, P ＜ 0. 05) ,also scores of group B were lower than those of group A at 10 min and 30 min(F=0.654,P＞0.05). PAEDS scores of group A were lower than those of group C at 20min and 30min(t =3.256,3.778,4.556,4.223 ,all P＜0.05). At 20min and 30min CHEOPS scores of group C were higher than those of group A and B ( F =1. 987, P ＞ 0.05 ). ConclusionPost-operative analgesia combined with parental presence could decrease the incidence of emergence agitation after sevoflurane anesthesia in children.

Objective To evaluate the prevalence of low bone mineral density in patients with inflammatory bowel disease(IBD) and to identify its risk factors. Methods A cross-sectional survey was carried out in IBD patients. Anthropemetric measures, biochemical markers of nutrition and bone mineral density measurement were completed for these patients as well as healthy control subjects. Results Seventy-seven Crohn's disease (CD) and 43 ulcerative colitis(UC) patients were enrolled, and 37 healthy volunteers were recruited as healthy controls(HC). The T value of CD patients, UC patients and HC was -1.72±1.20,-1.26±1.12 and-0.62±0.87 respectively and the T value of CD patients was significantly lower than that of HC (P=0.000). The prevelance of osteoporosis in CD, UC and HC was 23.3%, 14.0% and 0 respectively. The prevelance of osteoporosis in CD was higher than that in HC (P=0.003). Logistic regression analysis indicated that low BMI(BMI≤18.4 kg/m~2) was an independent risk factor for osteoporosis both in CD (OR=11.25,95% CI 3.198-39.580, P=0.000) and in UC (OR= 14. 50,95% CI 1.058-88.200, P=0.045) patients. Age, disease duration, clinical activity active index (CDAI), oral steroid therapy, immunosuppressant treatment and serum vitamin D concentration were not found to be correlated with osteoperosis in IBD patients. Conclusions Low bone mineral density is common in both CD and UC patients and low BMI is an independent risk factor for osteoporosis in IBD patients.
