ABSTRACT

Objective@#To summarize the clinical characteristics, virological and histopathological features, clinical outcome of Epstein-Barr virus-positive lymphoproliferative disease (EBV+LPD) in children.@*Methods@#The clinical and follow-up data of 13 children histopathologically diagnosed as EBV+LPD in the Department of Infectious Disease of Beijing Children's Hospital between January 2011 and December 2016 were summarized.@*Results@#Of the 13 patients, 5 were males and 8 females. The median age of disease onset was 6.0 years (range 1.3 to 15.0 years). The median duration between disease onset and diagnosis was 3 months (range 1 to 24 months). All the 13 patients had fever, 9 cases had hepatosplenomegaly and lymphoadenopathy, 4 cases had only lymphoadenopathy, 7 cases had reduced peripheral blood cells, 7 cases had lung involvement, 3 cases had central nervous system involvement, 3 cases had cardiac involvement, 3 cases had intestinal involvement, 2 cases had skin involvement and 1 case had abdominal mass. All the 13 patients underwent whole blood EBV-DNA PCR examination and the copies ranged from 1×108/L to 1×1011/L. Pathology of lymph node confirmed 6 cases, skin pathology confirmed 2 cases, lung pathology, ileum mucosa pathology, liver pathology, abdominal mass pathology and bone marrow pathology confirmed 1 case each. Among 13 patients, 9 cases presented with EBV-positive T cell lymphoproliferative disease(EBV+ T-LPD), 2 cases with hydroa vacciniforme (HV) and 2 cases with EBV-positive diffuse large B-cell lymphoma (EBV+ DLBCL) . All the patients were followed up for 2 days to 65 months after discharge. Among 9 cases of EBV+T-LPD, 1 case died in a short time, 1 case died after evolved to T-cell lymphoma, 2 cases recovered after hematopoietic stem cell transplantation, 1 case recovered after the chemotherapy of hemophagocytic lymphohistiocytosis(HLH) 2004 protocol and 4 cases were stable now. Of 2 cases of HV patients, 1 case died after evolved to HV like lymphoma and the other still have symptoms. Among 2 cases of EBV+ DLBCL, 1 case died shortly after discharge and the other was still stable after chemotherapy.@*Conclusions@#Chronic recurrent fever, lymphadenopathy and hepatosplenomegaly are the most common clinical manifestations in children with EBV+LPD. Involvement of lung, central nervous system, intestinal tract, skin and other organs are also involved frequently. For children with chronic fever of unknown cause and accompanied by lymphadenopathy and (or) hepatosplenomegaly, EBV + LPD should be considered highly when the whole blood EBV-DNA load continues to increase significantly, early biopsy of the proliferative lesion should be performed to make a definite diagnosis. The prognosis of EBV + LPD is poor, and some evolve to lymphoma, hematopoietic stem cell transplantation is an effective way to treat this disease.

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the clinical characteristics and long-term prognosis of herpes simplex virus encephalitis (HSE) in childhood and to analyze genotype of UNC93B1 and TLR3.</p><p><b>METHOD</b>Data of a total of 30 HSE patients admitted to Beijing Children's Hospital from January 2008 to September 2013 were retrospectively analyzed, the data included clinical manifestations, physical sign, auxiliary examination, therapy and long-term clinical prognosis. The family history obtained during follow-up visit was also analyzed for genetic predisposition. With parents' agreement, the blood specimens of patients were collected in EDTA anticoagulant tubes, the first 2 genetic etiologies UNC93B1 and TLR3 were sequenced, and the genetic susceptibility to HSE in childhood was summarized.</p><p><b>RESULT</b>(1) All the 30 patients (100%) had fever, 28 (93%) had seizure, 25 (83%) had altered state of consciousness, only 11 (37%) had personality changes, and in 8 (73%) appeared at or after 2 weeks of onset . (2) During the long-term follow up, 2 (7%) patients died after discharge, 23 patients (82%) had neurological sequelae, 13 patients (57%) had moderate, severe disability and vegetative state. (3) After sequencing of UNC93B1, and TLR3, one patient was found homozygous for a single-nucleotide substitution at position C.414C>G in exon 4 of UNC93B1 which affected the expression of UNC93B1, and may block or decrease the production of interferon. (4) Six single nucleotide polymorphisms (SNPs) were found in this study, their genotype frequency and gene frequency of Chinese were respectively searched in Genomes Project in NCBI and defined 1 000 genomes group. The genotype frequency of UNC93B1 rs7149 between 1 000 genomes group and HSE group was significantly different (χ² = 55.37, P<0.05). The frequency of CC type and C type was higher in HSE group, both of them had significant difference (χ² = 93.90, P<0.05, OR=61.563; χ² = 134.40, P<0.05, OR=12.491).</p><p><b>CONCLUSION</b>HSE lacks specific clinical manifestations, the long-term prognosis is poor. One HSE patient carrying a heterozygous mutation in UNC93B1 which may lead to the susceptibility to HSE and had harmful effect on long-term prognosis. The SNP UNC93B1 rs7149 may also have relationship with susceptibility to HSE and the children carrying CC genotype or C gene in this gene site maybe more susceptible to HSE.</p>

ABSTRACT

Objective To evaluate the post-puncture complications in children,and to evaluate the difference in the occurrence rate of headache and backache between patients who had 1 hour of supine recumbency and those who had 4 hours of supine recumbency,to provide evidence for the standardized lumbar puncture (LP) procedure of children.Methods Inpatients who were older than 3 and had diagnostic LP in the course of their treatment between Nov.2012 and Apr.2013 were enrolled.The LP was performed by the same investigator under the standardized institutional guideline for LP and the information of number of LP attempts,duration of LP and cerebrospinal fluid (CSF) drainage volume were recorded.After the procedure,all the children were randomly assigned into 2 groups:the test group had supine recumbency for 1 hour after LP,and the control group had it for 4 hours.For the first 5 days following LP,reports of headache and backache were recorded by another physician who didn't participate in this study.The difference in the occurrence rate of headache and backache between test group and control group was assessed by the chi-square test or Fisher's probabilities in 2 × 2 table.And a Logistic regression analysis was performed to assess the risk factors for the occurrence of the headache and backache.Results The overall frequency of headache was 4.6% (4/87 cases).The frequency of headache was not significantly different between the test group (2.4%) and control group (6.7%) (P =0.617).And the overall frequency of backache was 19.5 % (17/87 cases),and it was not significantly different between the 2 groups (test group:21.4%,control group:17.8 %,P =0.668).In a Logistic regression analysis,age (P =0.011,OR:6.884,95% CI:1.398-33.906) and the previous history of lumbar puncture (P =0.018,0R:0.126,95 % CI:0.026-0.618) were significant risk factors for the occurrence of backache.The risk of backache in children with more than 2 times of LP was decreased.And the risk was higher in the children older than 6 years than those younger than 6 years.Conclusions Headache and backache were the most frequent post-puncture complications in children.There was no difference between short duration (1 hour) of supine recumbency and long duration (4 hours) in preventing the occurrence of headache and backache after LP.

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the clinical features, imaging characteristics, diagnosis and treatment of a case with central nervous system infection caused by Exophiala dermatitidis, as well as to review the related literature.</p><p><b>METHOD</b>Associated literature and clinical data of an 8-year-old boy who was diagnosed as central nervous system infection caused by Exophiala dermatitidis in Beijing Children's Hospital Affiliated to Capital Medical University and hospitalized twice from 2012 to 2014 were analyzed retrospectively.</p><p><b>RESULT</b>The boy was 8 years old with the chief complaint of dizziness for 2 months, intermittent fever for 1 month accompanied with spasm twice. He was diagnosed as bile ducts space-occupying lesions 2 years ago, when the pathological diagnosis was fungal infection. The boy was treated with irregular anti-fungal therapy. Then the boy developed nervous symptoms, impaired consciousness and abnormal physical activity that developed gradually. After hospitalization the cerebral MRI of the boy showed space-occupying lesions accompanied with edema of surrounding area. Filamentous fungi was found by brain biopsy, which was culture positive for Exophiala dermatitidis. After diagnosis the boy was treated with amphotericin B (AMB), voriconazole and 5-Fu, as well as symptomatic treatment. The state of the boy was improved gradually. Two months later, the boy could communicate with others normally and move personally. The lesions and edema seen on the MRI was decreased moderately. Accordingly, the boy was treated with oral voriconazole maintenance treatment for about 1 year and 4 months after discharge. During this period, the state of him was stable without symptoms. The lesions shown by MRI did not disappear but decreased on regular examination. However, recently the disease of the boy progressed again, with dizziness, neck pain, headache and progressive nervous symptoms (intermittent spasm, inability to cough, and impaired consciousness). The boy died at last, even with the active treatment at the second hospitalization. Exophiala dermatitidis was culture-positive again in his CSF, and was confirmed by PCR successfully.</p><p><b>CONCLUSION</b>The central nervous system infection caused by Exophiala dermatitidis is rare. Clinical features of this disease were similar to those of other fungal CNS infection, cerebral MRI of which could show the similar lumpy lesions. Diagnosis of the disease should be based on pathology and culture.</p>

ABSTRACT

Objective To delineate the m orp hology and ecology of a new human schistosome species. Methods (1)Adult schistosomes were obtained from infected mice and rabbi ts with cercariae shedding from snails which were infected with miracidia devel oping from the eggs in feces of acute schistosomiasis patients. (2)T he rabbits were dissected during 60-100 d infection period of cecariae, and thei r bladders were taken out for detecting eggs in the urine. (3)Schistosome eggs i n the feces of patients were examined with microscopy. Results (1)There were two types of male worms: one was with an average o f size 8.76 mm long and 0 43 mm wide while the other with an average size of 2 41 mm long and 0 091 mm wide and with undeveloped gynecophoral canal which ap peared in front of ventral sucker (2)There were two types of female worms: one was with an average of size 10 73 mm long and 0 74 mm wide while the other wi th an average of size 3 43 mm long and 0 12 mm wide and was fine, semitranspar ent and tape like with undeveloped ovary and vitellaria. Less than 10 eggs or none were found in t he uterus. (3)There were a lot of degenerated and black eggs in the feces of 2 p atients. (4) Schistosome eggs were detected in the urine and miracidia were hatc hed out from 8 out of 16 infected rabbits.(5) Others: 8 worms were detected in 1 mouse out of 12 dissected mice for evaluation of infectious water with sentry m ice in spite of that no Oncomelania snails were found in the area. Cercariae stayed on water surface in lying position like a c omma. The eggs returned forwardly a fter growing behind the ovary in female worm. ConclusionAccording to the primary investigation in morphology an d ecology, the new schistosome obtained is distinct from the 6 well defined ty p es of human schistosome. It is considered that a new schistosome species should be foun d and temporarily nominated as Schistosoma nanjingi( S.n.)

ABSTRACT

Seventy dogs were irradiated -with 300. 325, or 350 rad of gamma rays from a 60Co sourse. Half of them were used as controls and the other 35 animals were divided randomly into four groups and were experimentally treated with different regimes.In the first group there were 9 treated, animals and an equal number of control animals 5 all the animals were irradiated with 300 rad. The treatment consisted of a blood transfusion on the 16th day after radiation exposure as well as several antibiotics and other medications. 8 out of the treated animals and one of the controls survived the gamma irradiation.In the second group, ten animals were exposed to 350 rad and 8 to 325 radand they were divided equally into treated and control groups. In spite of early use of blood transfusion and antibiotics, all the treated animals as well as those of the control group died of severe mycotic infections.In the third group, 325 rad was given to the dogs. All 7 dogs of the controls died and two out of the 7 treated dogs survived. The treatment was the same as that of the first group but no blood transfusion was used.In the fourth grou'p?ten animals were irradiated with 350 rad and another ten with 325 rad. They were divided equally into control and treated groups. All the ten controls died. The treated group was given the same treatment as the first group. In addition, tetracycline was given in case there was fever in 'the critical phase of the sickness, and the dosage of tetracycline was doubled whenever fever persisted or recurred. All the treated animals survived.Early blood transfusion was found to be better in its therapeutic effect than late transfusion.
