Objective To explore the effect of parvovirus B19 (VB19) infection on pediatric leukemia patients. Methods The pediatric leukemia patients were enrolled in the study in the Children's Hospital of Soochow University. Expression levels of VB19-DNA-PCR were detected using the polymerase chain reaction. Positive patients would be monitored and treated by conventional treatment as well until VB19 gene became negative. The data was compared according to the VB19 clearance time, clinical symptoms and blood counts to evaluate the effect. Results In the 3009 samples from 824 pediatric leukemia patients, there were 36 samples (1.2%) from 12 cases (1.5%) of pediatric leukemia paients with positive VB19 infection. Among the positive patients, 11 cases (1.9%) were from 582 with acute lymphoblastic leukemia (ALL) patients and 1 (0.45%) was from 212 with acute myeloid leukemia (AML). According to the treatment stage, 3 cases were in initially diagnosed period, 2 cases in early stage of consolidation chemotherapy, 4 cases in delayed enhanced chemotherapy period, and 3 cases in maintenance chemotherapy period. According to the treatment response, 4 cases were in continuous treatment, 2 cases were sensitive to treatment, and 3 cases were drug resistant. In the drug resistance group, 2 cases developed into the pure red cell aplastic anemia (PRCA). After treatment, one was recovered from PRCA with VB19 cleared, the other one remained PRCA with continuously positive VB19. Conclusions More VB19 virus infection in pediatric ALL happened in delayed enhanced chemotherapy period. The persistent presence of VB19 infection on pediatric leukemia patients is closely related with PRCA.

Objective To study the feasibility of in vitro release of γ-interferon tests (IGRA) in screening of tuberculosis for children with close TB contacts. Methods 185 children with close TB contacts were detected by IGRA at the pediatric clinic in our hospital. Results In IGRA-positive group, the rate of strong positive PPD (PDD≥15 mm) was 50.9%, which was higher than 9.1% in IGRA-negative group (X2 =37.263, P < 0.00). The morbidity rate for children with close TB contacts was 30.2% in IGRA-positive group, and it was significantly higher than 3.0% in IGRA-negative group (X2 = 28.928, P < 0.00). The sensitivity was 80% and the specificity was 77.6% for IGRA screening in children who had close contacts with TB patients. The sensitivity would be 95.0%, as the test was combined with PPD test. Conclusions IGRA screening in children with close TB contacts can increase the detection rate of tuberculosis and reduce imaging screening.

OBJECTIVE:
To analyze the clinical characters and treatment of nasopharyngeal tuberculosis, and to provide a scientific basis for improving clinical diagnosis of nasopharyngeal tuberculosis.
METHOD:
The clinical materials of 50 patients diagnosed as nasopharyngeal tuberculosis in Guangzhou Chest Hospital were reviewed and analyzed. All the 50 patients were given regular antituberculosis treatment with 3HRZS(E)/9HR(E) for one year, and were treated through nasal spray with combination medication of isoniazid, rifampicin and streptomycin injection solution for 3 months.
RESULT:
All patients were cured through regular antituberculosis treatment for one year, and no recrudescence cases were found in 2 years of follow-up.
CONCLUSION
Nasopharyngeal tuberculosis is rare and the clinical manifestation is atypical. It is extremely easy to cause clinical misdiagnosis. A full understanding of the pathogenesis, timely clinical characters under nasopharyngoscope and histopathological examination results are the keys to diagnosis, and to giving regular antituberculosis treatment to obtain satisfactory curative effect.

Objective:To explore the application of scenario simulation teaching based on PBL in communication skills training of hematology students in Children's Hospital.Methods:The training of doctor-patient communication skills was conducted among trainees who had the standardized residency training at the Department of Hematology of the Children's Hospital of Soochow University. All the residents were randomized into the control group and observation group by lottery, with 24 residents in each group. The control group adopted the traditional narrative teaching method, and the observation group adopted PBL combined with scenario simulation teaching method. The Liverpool communication skills assessment scale (LCSAS) was used to compare the differences between the two groups before and after training, and the differences between the two groups after training. Then the degree of residents' recognition of these two teaching methods was investigated. Finally, the examination results were used to evaluate knowledge mastery of doctors in department of hematology. SPSS 20.0 was used for Chi-square test and t-test. Results:LCSAS scores of the two groups before training were respectively (11.61±2.21) and (11.95±2.22), with no statistically significant difference ( P >0.05). After PBL-based scenario simulation teaching and training in the observation group, the LCSAS score of the observation group (27.41±2.53) was higher than that of the control group (23.30±1.81), and the difference between the two groups was statistically significant ( P<0.05). Questionnaire survey results showed that the favorable rating rate of PBL-based scenario simulation teaching was 91.67% (22/24), higher than that of the traditional narrative teaching method [62.50% (15/24)], and the difference was statistically significant ( P<0.05). The examination of students' mastery of professional knowledge showed that after the PBL-based scenario simulation teaching and training, the trainees had a better grasp of knowledge and a higher score, with excellence rate of 91.67% (22/24), which was higher than 66.67% (16/24) of the control group, with a statistically significant difference ( P<0.05). Conclusion:The scenario simulation teaching based on PBL could improve the communication ability and professional knowledge of trainees taking standardized residency training in the department of hematology, and the trainees are highly satisfied with this teaching method.

Objective:To explore the risk factors for hemophagocytic syndrome (HPS) in childhood Epstein-Barr virus (EBV)-associated infectious mononucleosis (IM).Methods:From January 2013 to December 2017, the medical charts of all children who were diagnosed with EBV-associated IM and HPS in Children′s Hospital of Soochow University were analyzed retrospectively. Statistical analyses were performed using SPSS version 22.0.Results:A total of 316 IM and 59 HPS were enrolled. The age was (4.26 ± 2.95) years old with a male-to-female ratio of 1.2∶1. In addition to the diagnostic criteria of HPS, there were significantly lower rates of fever >10 d, hepatomegaly, jaundice, alanine aminotransferase >500 U/L, aspartate aminotransferase >500 U/L, LDH >1 000 U/L, C-reactive protein >50 mg/L and hypoalbuminemia in children with EBV-associated IM compared to those with HPS, and the differences were statistically significant ( P<0.05). Multivariate Logistic regression analysis showed that fever >10 d, eyelid edema, lymphadenopathy and purulent tonsils were independent predictors of HPS in children with EBV-associated IM ( P<0.05). Hepatomegaly and fever >10 d were risk factors ( OR = 16.079 and 12.138, 95% CI 2.788 to 92.744 and 2.878 to 51.180). Eyelid edema, lymphadenopathy and purulent tonsils were protective factors ( OR = 0.087, 0.006 and 0.031; 95% CI 0.010 to 0.723, 0.001 to 0.058 and 0.007 to 0.146). Conclusions:Hepatomegaly and fever >10 d are the risk factors for hemophagocytic syndrome in childhood EBV-associated infectious mononucleosis.

Objective:
To evaluate the efficiency and safety of low intensity conditional regimen for children with Fanconi anemia (FA) receiving allogenic hematopoietic stem cells transplantation (allo-HSCT).
Methods:
Four patients diagnosed as Fanconi anemia were enrolled in this study. One patient received HLA-identical sibling donor hematopoietic stem cell transplantation, two patients underwent unrelated donor matched (UD) HSCT, and one patient received unrelated cord blood transplantation. The conditional regimen consisted of Busulfan with low dose of cyclophosphamide.
Results:
All 4 cases succeeded in allo-HSCT. The median time for neutrophils engraftment was 11(9-15) day, median time to platelets (PLT) engraftment was 12 (8-28) day. One case occurred with grade I of aGVHD, 1 case with hemorrhagic cystitis. No patient happened with hepatic veno-occlusive disease (VOD).
Conclusion
Low intensity of conditional regimen is efficient and safe which should be recommended for FA patients with HSCT.

Venous thromboembolism (VTE) is a complication in children with acute lymphoblastic leukemia (ALL). The Chinese Children's Cancer Group-ALL-2015 protocol was carried out in China, and epidemiology, clinical characteristics, and risk factors associated with VTE were analyzed. We collected data on VTE in a multi-institutional clinical study of 7640 patients with ALL diagnosed in 20 hospitals from January 2015 to December 2019. First, VTE occurred in 159 (2.08%) patients, including 90 (56.6%) during induction therapy and 108 (67.92%) in the upper extremities. T-ALL had a 1.74-fold increased risk of VTE (95% CI 1.08-2.8, P = 0.022). Septicemia, as an adverse event of ALL treatment, can significantly promote the occurrence of VTE (P < 0.001). Catheter-related thrombosis (CRT) accounted for 75.47% (n = 120); and, symptomatic VTE, 58.49% (n = 93), which was more common in patients aged 12-18 years (P = 0.023), non-CRT patients (P < 0.001), or patients with cerebral thrombosis (P < 0.001). Of the patients with VTE treated with anticoagulation therapy (n = 147), 4.08% (n = 6) had bleeding. The VTE recurrence rate was 5.03% (n = 8). Patients with VTE treated by non-ultrasound-guided venous cannulation (P = 0.02), with residual thrombus (P = 0.006), or with short anticoagulation period (P = 0.026) had high recurrence rates. Thus, preventing repeated venous puncture and appropriately prolonged anticoagulation time can reduce the risk of VTE recurrence.
