RESUMO
OBJECTIVE@#To analyze the changes and characteristics of pediatric outpatient visits in a general hospital before and after the coronavirus disease (COVID-19) epidemic.@*METHODS@#Based on the registration data of pediatric outpatient visits in the information system (HIS)of Beijing Tsinghua Changgung Hospital, from January 1 2018 to December 31 2020, aged 0 to 16 years, we analyzed the changes of outpatient visits before and after the epidemic, focusing on respiratory infection including influenza. The relationship between the outpatient visits and age and quarterly distribution were also studied.@*RESULTS@#(1) Respiratory infection accounted for the majority of outpatient visits in 2018 and 2019 (60.6% and 60.5%, respectively). Non-respiratory infection accounted for the main proportion of outpatient visits in 2020, while respiratory infection accounted for only 47.4%. Annual respiratory infection visits, respiratory infectious diseases visits especially influenza visits all decreased significantly in 2020 compared with that in 2018 and 2019 (P < 0.05). (2)Respiratory infection visits were highest in the infant group, lowest in the school age group (P < 0.05) and highest in the fourth quarter each year. It decreased significantly in the second quarter of 2020 with statistical significance when compared with the other quarters of 2020(P < 0.05). (3)Influenza accounted for the highest proportion of respiratory infectious diseases visits in each year. It was highest in first quarter, which was significantly different from the other quarters of the year (P < 0.05). There were different distributions of influenza visits throughout 2018 and 2019, while it was only distributed in the first quarter and 99% in January in 2020.@*CONCLUSION@#The respiratory infection and influenza visits have decreased significantly in our pediatric outpatient department after the COVID-19 epidemic, which is considered closely related to the lifestyle and personal protection after the epidemic. It is recommended that health education on respiratory infection and influenza prevention should be strengthened, especially in winter and spring, to promote the development of good respiratory and hand hygiene habits.

Objective@#To compare the efficacy and safety of mycophenolate mofetil versus cyclosporine A in treating children with primary refractory nephrotic syndrome.@*Methods@#Conducted a prospective randomized controlled clinical trial in 62 pediatric patients (including 44 boys and 18 girls), age ranged from 2.1 to 17.0 years; 32 cases presented with frequently relapsing nephrotic syndrome (FRNS) and 30 cases presented with steroid-resistant nephrotic syndrome (SRNS), who were admitted to department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics from October 2013 to October 2015. The patients received either mycophenolate mofetil (20-30)mg/(kg·d) or cyclosporine A (3-5)mg/(kg·d) randomly, on the basis of prednisone treatment. Follow-up interview was conducted regularly for at least one year. Efficacy rate, relapse rate, time required for induction of remission, relapse-free period and prednisone dosage were compared between the two groups.@*Results@#(1) Renal histologic examination, which was available for 17 patients, revealed minimal change disease in 8 patients, mesangial proliferative glomerulonephritis (MsPGN) in five, membranous nephropathy in two, and focal segmental glomerulosclerosis (FSGS) in two. (2) Comparison of mycophenolate mofetil versus cyclosporine A in children with FRNS: There were 14 patients with FRNS in mycophenolate mofetil group and 18 patients with FRNS in cyclosporine A group respectively. The relapse rate (episodes/year) in cyclosporine A group was lower than that of mycophenolate mofetil group (1.0 (0.0, 1.0) vs. 1.0 (1.0, 3.0), Z=-2.405, P=0.016). The relapse-free period (months) in cyclosporine A group was longer than that of mycophenolate mofetil group (10.0 (5.7, 12.1) vs. 5.0 (1.0, 11.0), Z=-1.984, P=0.047). No significant difference in dosage of prednisone was found between cyclosporine A and mycophenolate mofetil groups when followed up for 1 year. (3) Comparison of mycophenolate mofetil versus cyclosporine A in children with SRNS: The efficacy rate was 6/14 in mycophenolate mofetil group and 13/16 in cyclosporine A group. The complete remission rate was 4/14 in mycophenolate mofetil group and 12/16 in cyclosporine A group (P<0.05). The time (months) required for induction of remission in cyclosporine A group was significantly shorter than that of mycophenolate mofetil group (1.0 (1.0, 2.0) vs. 3.0 (2.5, 4.0), Z=-2.529, P=0.011). No significant differences were found between the two groups with respect to relapse-free period and relapse rate. (4) Except that one patient developed hypertensive encephalopathy in cyclosporine A group, no other serious adverse events were recorded. There were no significant differences between two groups with respect to adverse events.@*Conclusion@#Our results indicated that both mycophenolate mofetil and cyclosporine A were effective in the treatment of children with refractory nephrotic syndrome. Cyclosporine A was superior to mycophenolate mofetil in preventing relapses in patients with FRNS and inducing complete remission in patients with SRNS. Although most patients were able to tolerate mycophenolate mofetil and cyclosporine A, but the toxicity and safety of cyclosporine A should be monitored closely.

Objective To investigate the changes of serum protein fingerprint in patients with lung cancer with deep venous thrombosis.Methods Eighteen case patients with lung cancer were selected,including 8 case of lung cancers with thrombosis and 10 cases of lung cancers with no thrombosis.Surface enhanced laser desorption ionization protein-time of flight mass spectrometry (SELDI-TOF-MS) was used to analyze serum protein content of two groups in the same mass to charge ratios(M/Z),then drew the protein peaks that content difference was statistically significant.Results The M/Z of lung cancer with thrombus group and control group were 5911,1216,4187,1019,4293,the protein peaks had significant differences between the two group (43.81±7.74,6.37±5.02,2.97±0.35,35.96± 12.10,9.65±4.37;15.35± 12.69,2.06±0.37,4.67± 1.35,15.94±6.47,14.65±8.80;t =5.334,4.800,2.981,4.639,4.596;P< 0.05).Compared with the control group,the decrease of protein peak M/Z were 5911,1019,1216,and the increase of protein peak M/Z were 4293,4187 in the deep venous thrombosis group.Conclusion In the serum of patients with tumors SELDI profiles M/Z are 5911,4293,4187,1019,1216 of SELDI protein fingerprinting can be considered in patients with thrombosis of tumor specific markers.
RESUMO
Objective To study the clinical and genetic features of Lowe syndrome. Methods The clinical data and test results of OCRL gene from two children with Lowe syndrome were analyzed. The related literatures were reviewed. Re-sults Two male patients all presented with low molecular proteinuria, hypercalciuria, rickets and nephrolithiasis. Patient 2 had renal tubular acidosis, glycosuria and cryptochism. Patient 1 was found to have abnormal vision and congenital cataract soon after birth and treated surgically. Patient 1 also had psychomotor retardation and the cranial magnetic resonance ima-ging (MRI) showed agenesis of the corpus callosum. Patient 2 did not have obviously extra-renal symptoms, but was found to have mild cataract by a meticulous ophthalmological examination. MRI showed cerebral hypoplasia and myelination delay and mental retardation was gradually appeared during follow-up. Two OCRL gene mutations were detected. A splice site mutation NG_008638.1:g.46846-46848delTAA/insC was found in patient 1 and a frame shift mutation NM_000276.3:c.321delC in exon 5 was found in patient 2. Both mutations were not reported previously. Conclusions The diagnosis of Lowe syndrome is mainly by clinical manifestations and test of OCRL gene. Lowe syndrome needs to be included in the differential diagnosis of a patient with congenital cataract and renal tubulopathy. Two novel mutations in the OCRL gene were identiifed.
RESUMO
We retrospectively analyzed the clinical manifestations,treatments and prognosis of infective endocarditis (IE)associated with renal lesions in children.There were 23 confirmed IE cases who were admitted to the Capital Institutes of Pediatrics from 1992 to 2012.There were 6 cases (26%) with renal lesions.Renal lesions included asymptonatic microscopic hematuria(1 case),asymptomatic proteinuria (1 case) and acute nephritic syndrome (4 cases).There were 3 cases of acute renal injury (AKI) resulted from nephritis accompanied with acute heart failure.The serum level of C3 was lower in patients with renal lesions than patients without renal lesions (P < 0.05),but the clinical manifestations,physical signs and other laboratory findings were the same.Patients of both groups were treated with antibiotics.All patients were recovered and discharged.The average hospital days were (39.2-± 15.2)days for patients with renal lesions and (34.9-± 19.2) days for patients without renal lesions (P > 0.05).Renal lesions secondary to IE are relatively common in IE patients in children.Most of renal lesions can be improved by effective antibiotics.Prognosis of those patients accompanying with AKI is bad.

Objective To improve recognition of posterior reversible encephalopathy syndrome (PRES) in children. Methods Two children with PRES admitted to children's hospital were included. Clinical data were retrospectively studied and related literatures were reviewed. Results The primary diseases of the two patients are systemic lupus erythematosus and nephritic syndrome, respectively. They all developed an acute onset of headache, visual changes, consciousness disturbance, hypertension and seizures. Cranial MRI showed bilateral parietal, temporal and occipital cortical or subcortical lesions with hypointensity on Tl-weighted imaging and hyperintensity on T2-weighted imaging. Clinical symptoms resolved soon and radiographic recovery occurred within 14 to 21 days with prompt anti-hypertension treatment and supportive care. Among the mechanisms which might contribute to the development of PRES, acute elevated blood pressure seems to be the most important factors in these two cases. Prompt anti-hypertension treatment usually can reverse the PRES lesion. Conclusions It is important to improve cognition of PRES in children. Delayed treatment can cause permanent neurological impairment. Doctors should be alert to this syndrome. Early diagnosis and prompt treatment are very important. (J Clin Pediatr,2010,28(2):168-170)
