Objective:To identify and improve the weakness in different clinical practice teaching hospital,and enhance the quality of practical teaching.Methods:A total of 291 trainees majoring in clinical medicine in grade 2016 in a medical college in Shenyang who practiced in different clinical teaching hospitals and participated in the objective structured clinical examination(OSCE)were enrolled.The OSCE scores was analyzed with one way ANOVA and Kruskal-Wallis statistic methods to identify the weakness in clinical practice teaching and improve the teaching quality.Results:In the standardized patient consultation and physical examination results,the passing rate and average score of H hospital was the lowest.The average score of trainees in H hospital was statistically significant compared to that in A,B,F,G,K,and L hospitals(P＜0.01).In terms of skill operation scores,H hospital had the lowest pass rate and average score.The average score of interns in H hospital was statistically significant compared to that in A,D,E,F,G,I,J,K hospitals(P＜0.01).In the interpretation of auxiliary examination results,the passing rate and average score of H hospital was the lowest.The average score of interns in A and H hospital was significantly different from that of B and J hospitals(P＜0.01).Conclusions:There are great differences in the practice effect of students in different clinical teaching hospitals.Medical colleges and universities should strengthen the management of clinical teaching hospitals to ensure the homogeneity of clinical practice teaching quality.
RESUMEN
Objective:To investigate the value of endoscopic retrograde cholangiopancreatography(ERCP)and related techniques in the diagnosis and treatment of chronic pancreatitis in children.Methods:The clinical data of 16 children with chronic pancreatitis diagnosed in the Department of Gastroenterology at Beijing Children′s Hospital from January 2021 to January 2022, who had ERCP indications were analyzed retrospectively, including age, sex, operation time, postoperative complications and follow-up data.Results:Thirty nine ERCP operations were performed in 16 children, with the age of (7.20±2.51) years old, and the minimum weight of 13 kg.There were 7 males and 9 females.The clinical manifestations were upper abdominal pain in all cases, 3 patients with dyspnea, 1 patient with gastrointestinal bleeding, and 1 patient with diabetes.In terms of etiology, 16 cases were diagnosed by ERCP including, 7 cases with pancreatic divisum, 1 case with abnormal pancreaticobile duct confluence.Among the 16 children, 11 had gene examination with 9 gene mutations (including 7 cases SPINK1 mutation, 1 case PRSS mutation, and 1 case CFTR mutation).The operation time was 30 to 65 minutes, and the median was 43 minutes.The operation time was negative correlation with age, while there was no correlation with the anatomical structure abnormality or the gene mutation.Among the 16 children, 15 were placed with pancreatic duct stents, with a success rate of 93.8%.Three children had postoperative pancreatitis, the rest had hyperamylasemia.Postoperative complications were not related with the age, the anatomical structure abnormality or the gene mutation.All children had been followed up for more than one year.All children have not suffered from pancreatitis again, and the body mass index had increased significantly after operation than before( P<0.05).The ERCP operation was performed 2 to 4 times in children after stent replacement, and the time of stent replacement ranged from 3 months to 12 months. Conclusion:The main causes of chronic pancreatitis in children are anatomical abnormalities or gene mutations.ERCP and related techniques are minimally invasive, safe and effective in the treatment of chronic pancreatitis.
RESUMEN
Objective:To investigate the clinical features and risk factors of the extraintestinal manifestations(EIM)in children with ulcerative colitis(UC).Methods:A retrospective case-control study was conducted.The clinical data of 99 children with UC diagnosed in Department of Gastroenterology, Beijing Children′s Hospital, Capital Medical University from January 2016 to December 2021 were analyzed.According to whether the patients had EIM or not, they were divided into EIM-positive group and EIM-negative group.Rank sum test, χ2test or Fisher′s exact test were used to compare the variables between the 2 groups, including the clinical features, laboratory examination results and treatments.The Logistic regression was used to analyze the risk factors of EIM in children with UC. Results:A total of 99 children with UC were enrolled, including 57 males and 42 females; the age of onset was 10.3(6.4, 12.6)years, and the course of disease was 4.2(1.6, 10.1)months.The patients were mainly characterized by extensive disease(E3)and pancolitis(E4)(69/99, 69.7%), moderate to severe activity(63/99, 63.6%)and moderate to severe inflammation of colonic mucosa(89/99, 89.9%). There were 77 patients(77.8%)in the EIM-negative group and 22 patients(22.2%)in the EIM-positive group, of which 5 patients had two types of EIMs; the most common EIMs were oral ulcers(9 cases), joint lesions(7 cases), and skin lesions(6 cases). Compared with the EIM-negative group, those in the EIM-positive group, such as the E4 type(77.3% vs 44.2%, χ2=7.513, P=0.006), moderate to severe activity(81.8% vs 58.4%, χ2=4.041, P=0.044), pediatric ulcerative colitis activity index score[47.5(35.0, 57.5)score vs 35.0(25.0, 50.0)score, Z=-2.260, P=0.024], the proportion of C-reactive protein≥8mg/L at diagnosis(54.5% vs 19.5%, χ2=10.607, P=0.001), erythrocyte sedimentation rate[30.0(13.8, 47.8)mm/h vs 10.0(4.0, 19.5)mm/h, Z=-3.918, P<0.001], the proportion of glucocorticoid treatment within one year after diagnosis(77.3% vs 49.4%, χ2=5.403, P=0.020)and the proportion of biological agents treatment(45.5% vs 23.4%, χ2=4.112, P=0.043)were significantly higher; the E3 type were significantly lower than those in the EIM-negative group(0 vs 23.4%, χ2=4.813, P=0.028), and the differences were statistically significant.Multivariate Logistic regression analysis showed that erythrocyte sedimentation rate at diagnosis was an independent risk factor of EIM in children with UC( OR=1.063, 95% CI: 1.025~1.103, P=0.001). Conclusion:The UC patients with EIM had more extensive lesions, more severe disease activity, significantly increased inflammatory indicators, and more commom glucocorticoid and biologic therapy.Increased erythrocyte sedimentation rate was an high risk factor of EIM in children with UC.
RESUMEN
Objective:To assess the value of double-balloon enteroscopy(DBE)in the treatment of Peutz-Jeghers syndrome(PJS)polyp with intussusception in children.Methods:A total of 14 cases with PJS polyp with intussusception were collected in Gastroenterology Department of Beijing Children′s Hospital Affiliated to Capital Medical University from July 2019 to January 2023.The general information, clinical manifestations, history of surgeries, abdominal ultrasound, enteroscopy and postoperative outcomes were retrospectively analyzed.Results:Fourteen cases with intussusception of PJS(including nine boys and five girls) were enrolled, and the average age was(10.25±2.52)years.There were 21 small intestinal intussusceptions in 14 cases, including eight cases of single intussusception and six cases of multiple intussusceptions.All the patients underwent DBE examination and treatment.A total of 215 small intestinal polyps were removed, no direct complications such as bleeding or perforation were found during the operation.Twelve cases were confirmed intussusception relieved by DBE, and the average maximum diameter of polyps causing intussusception was(4.38±1.43)cm.In addition, DBE did not reach the site of intussusception polyp in one case, and another case developed intestinal obstruction after DBE operation, which were treated by surgery.Conclusion:DBE provides a relatively effective method for the treatment of PJS polyps with intussusception without complete ileus in children.
RESUMEN
Objective:To summarize the clinical manifestations and determine the molecular etiology for three KCNMA1-related neurological disorders.Methods:A retrospective clinical data analysis was performed on 3 patients with clinically and genetically diagnosed neurological diseases related to KCNMA1 gene variants who were diagnosed and treated in the Department of Pediatrics, Xiangya Hospital of Central South University from January 2020 to December 2022.Results:Case 1, a 4-year-old and 8-month-old female, was diagnosed with " episodes of head-raising and lowering for 11 months". The electroencephalogram (EEG) showed background theta rhythm in the occipital area, with mainly sharp waves and peaks in the bilateral central, parietal, occipital and temporal areas. Slow waves were scattered or paroxysmal, affecting the central, parietal, and temporal areas on the right side. Levetiracetam was given as an anti-epileptic treatment, and the seizures were completely controlled. Physical examination revealed unclear articulation and short stature. The patient′s mental development has been delayed since childhood. After 2 years of rehabilitation treatment, his motor development was normal and his language development was slightly delayed. Whole-exome sequencing found a novel c. 1807A>G (p.Thr603Ala) mutation in the KCNMA1 gene, which was graded likely pathogenic (LP). Case 2, a male, 1 year and 4 months old, went to the hospital because of " recurrent stupor attacks for more than 6 months". Nearly 20 epileptic events were detected on the electroencephalogram. Levetiracetam, sodium valproate and clonazepam were administered successively. Seizure treatment, complete seizure control. Brain magnetic resonance imaging (MRI) showed poor cerebellar development. Development was lagging behind that of normal children of the same age. Whole-exome sequencing found a novel c. 756C>A (p.Phe252Leu) mutation in the KCNMA1 gene, which was graded LP. Case 3, a 16-month-old female, went to the hospital because of " trembling upper limbs, slurred speech for more than 10 years, and unsteady gait for 8 years." The electroencephalogram showed no abnormalities, and brain MRI showed cerebellar atrophy. Physical examination: unclear speech, unsteady grasping of objects with both hands, muscle strength of limbs level 4, and ataxic gait. Whole-exome sequencing found a novel c. 1051T>C (p.Ser351Pro) mutation in the KCNMA1 gene, which was graded LP.Conclusions:The core phenotypes of KCNMA1 gene mutation-related neurological diseases include epilepsy, neurodevelopmental disorders and paroxysmal dyskinesia, and cerebellar atrophy is common in brain MRI.
RESUMEN
Objective:To compare the efficacy of combination therapy on cyclic vomiting syndrome(CVS)in children, and improve the efficacy of CVS treatment in the future.Methods:This study retrospectively analyzed patients′ medical records of CVS, which were admitted to Digestive Department of Beijing Children′s Hospital from 2012 to 2019.The treatment regimen was A(Cyproheptadine+ Doxepin+ Valproate), B(Propranolol+ Cyproheptadine), or C(Propranolol+ Amitriptyline). Meanwhile, the patients should take drugs more than three months.The clinical data of 42 cases were analyzed retrospectively, and the treatment effect after discharge was followed up by telephone until October, 2020.Results:Among the 42 cases, 17 were male and 25 were female, whose mean age of onset was (4.65±3.23) years, and the age of diagnosis was (6.79±3.58) years.The main accompanied symptoms were abdominal pain and upper gastrointestinal bleeding.Forty-two patients were moderate/severe CVS.The regimens A, B and C were observed in 7, 11, and 24 patients, respectively.The age at improvement was(8.17±4.12)years.The course of treatment was(1.37±0.96)years.The age at follow-up was(10.32±4.03)years.During the 1-year follow-up, 35 cases were effective, and the efficiency was 83.3%.Among them, 23 cases had no paroxysmal vomiting and 7 cases had no effect.There was no significant difference in therapy effects among group A, B and C. Between the effective group and non-effective group, there were statistical differences in the personal history of hiatus hernia( P=0.024), the weight at follow-up ( P=0.042), and the course of medication( P=0.020). Conclusion:The combination regimen has a higher effective rate in the treatment of CVS.There was no significant difference among the three regimens in the treatment of CVS.For children with refractory CVS, who can not be treated with combination therapy, individualized therapy should be further developed.

RESUMEN
Objective:To evaluate the efficacy and safety of Adalimumab(ADA) in the treatment of pediatric Crohn′s disease (CD).Methods:The clinical data of 20 CD patients treated with ADA at Beijing Children′s Hospital, Capital Medical University from September 2016 to September 2021 were retrospectively analyzed.The disease activity status and mucosal inflammation in CD patients were evaluated using the Pediatric Crohn′s Disease Activity Index (PCDAI) and Crohn′s Disease Endoscopic Severity Index(CDEIS). Data were compared between groups using the rank sum test or Fisher′ s exact test. Results:A total of 20 CD patients were recruited, including 12 males and 8 females.The mean age at diagnosis of CD was (9.5 ± 4.9) years old, ranging from 0.9-15.1 years old.The mean age of the first use of ADA was (10.4 ± 4.8) years old, ranging from 1.2-16.7 years old.The median duration of CD symptoms before ADA treatment was 0.9 (0.4, 1.7) years.The mean PCDAI score of 20 CD patients before ADA treatment was (28.5±19.8) points (range: 0-65.0 points). Of the 20 cases, 8 cases (40.0%) had severe disease activity, and 4 cases (20.0%) were in remission.A total of 15 CD patients underwent CDEIS assessment.The results showed that 9 patients had moderate to severe disease activity, and the symptoms were improved in 1 case under endoscopy.Ten patients (10/20 cases, 50.0%) received Infliximab (IFX) treatment preceding ADA treatment.IFX discontinuation was due to the loss of response(8/10 cases, 80.0%) and allergic reactions (2/10 patients, 20.0%). After 6 weeks of ADA treatment, the median PCDAI score of the 20 CD patients was 5.0 (0, 10.0) points, which was significantly lower than that before ADA treatment ( P<0.001). The clinical remission rate and clinical response rate of 16 patients with active CD treated with ADA for 6 weeks were 62.5% (10/16 cases) and 87.5% (14/16 cases), respectively.There were no significant differences in the clinical remission rate and clinical response rate between the patients who did not receive IFX and those who had previously received IFX(all P> 0.05). The median ADA treatment period was 5.5 (2.6, 17.8) months.During the follow-up period, 6 patients (6/20 cases, 30.0%) suffered from clinical recurrence of CD.At the end of the follow-up visit, seventeen patients(17/20 cases, 85.0%) maintained clinical remission, one had primary non-response and two experienced secondary non-response.Adverse events were reported in 7 patients, mainly including pneumonia (4 cases) or upper respiratory tract infection (2 cases). No tumor or other serious adverse events were recorded. Conclusions:ADA has good efficacy in inducing and maintaining clinical remission in pediatric CD patients, and does not cause serious adverse events.

RESUMEN
Objective:To summarize clinical and genetic features of infantile-onset inflammatory bowel disease(IO-IBD) patients.Methods:The clinical data of 48 IO-IBD patients from Beijing Children′s Hospital, Capital Medical University, including age of onset, family history, clinical manifestations and drug efficacy were retrospectively analyzed.Based on target gene panel, next generation sequencing (NGS) was performed for 43 patients, and further compared clinical features between gene mutation and non-gene mutation IO-IBD groups.Results:Among the 48 IO-IBD patients, 41 cases suffered from Crohn′s disease (CD) and 7 cases were ulcerative colitis (UC). The median age of onset was 2.00(0.24-6.00) months, and 45.8%(22/48 cases) of patients′ onset age was within 1 month.Diarrhea (48/48 cases, 100%), fever (45/48 cases, 93.8%) and hematochezia (37/48 cases, 77.1%) were the main clinical symptoms.Perianal lesions and rashes were common extraintestinal manifestations, accounting for 43.8%(21/48 cases) each.Among 41 CD patients, 73.2%(30/41 cases) had predominantly colonic disease (L2 type), and disease behavior was mainly nonstricturing and nonpenetrating (B1 type) (33/41 cases, 80.5%). Among 7 UC patients, 57.1%(4/7 cases) had predominantly pancolonic (E4 type). The surgical rate of the 48 IO-IBD patients was 12.5%(6/48 cases), the clinical remission rate was 50.0%(24/48 cases), and the mortality rate was 25.0%(12/48 cases). Among the 43 IO-IBD patients, 23 (23/43 cases, 53.5%) had meaningful gene mutations, of which 22 cases had mutations in interleukin-10 receptor A ( IL-10 RA) and 1 case with mutation in TTC37.A total of 11 mutation sites were detected in 22 patients with IL-10 RA mutations, including one novel mutation site c. 635G>C (p.R212P); 19 cases c. 301C>T (p.R101W) and 8 cases c. 537G>A (p.T179T) that were common mutation sites.Compared with non-gene mutation IO-IBD group, patients in gene mutation IO-IBD group had earlier onset age [0.3 (0.1-1.0) months vs.(6.27±5.64) months, P<0.001], higher proportion of malnutrition [14 cases(60.9%) vs.5 cases(25.0%), P=0.018], oral ulcers [14 cases(60.9%) vs. 30 cases(15.0%), P=0.006] and perianal lesions [17 cases(73.9%) vs.3 cases(15.0%), P<0.001], and the lower rate of clinical remission[7 cases(30.4%) vs.15 cases(75.0%), P=0.004]. Conclusions:IO-IBD patients had a high rate of monogenic mutation, and IL-10 RA gene mutation was the common mutation.IO-IBD patients developing with gene mutation were characterized by early age of onset, higher incidence of malnutrition, oral ulcers, perianal lesions, and the lower clinical remission rate.
RESUMEN
Objective To summarize the clinical data of the children with inflammatory bowel diseases (IBD),including Crohn's disease (CD) and ulcerative colitis (UC),and to analyze and compare the clinical features of very early-onset IBD (VEO-IBD) and late-onset IBD (LO-IBD).Methods A retrospective analysis of the clinical data of 184 cases of IBD hospitalized children diagnosed at Beijing Children's Hospital,Capital Medical University from January 2000 to December 2014.According to their ages of onset,the patients were divided into VEO-IBD group (＜6 years old) and LO-IBD group (6-16 years old);the patients with CD were divided into VEO-CD group (＜ 6 years old) and LO-CD group (6-16 years old);UC were divided into VEO-UC group (＜ 6 years old) and LO-UC group (6-16 years old).The clinical features among each group were analyzed and compared.Results A total of 184 IBD patients were included in the study,77 cases(41.8％) were VEO-IBD and 107 cases(58.2％) were LO-IBD.Comparison between VEO-CD group and LO-CD group indicated that abdominal pain was more common in LO-CD group (P ＜ 0.05),while diarrhea and hematochezia were more common in VEO-CD group (all P ＜ 0.05).In addition,comparison between VEO-UC group and LO-UC group indicated that abdominal pain was more common in LO-UC group(P ＜ 0.001),while diarrhea,fever,and oral ulcers were more common in VEO-UC group (all P ＜0.05).Both VEO-CD and LO-CD group were mainly ileocolonic[15/27 cases (55.6％),20/47 cases (42.6％)],non-narrow,non-penetrating [20/27 cases (74.1％),30/47 cases (63.8％)] and moderate-to-severe activity[23/27 cases(85.2％),37/47 cases (78.7％)].The incidence of perianal lesions in the VEO-CD group was as high as 51.9％ (14/27 cases),which was significantly higher than that in the LO-CD group (9/47 cases,19.1％) (P ＜ 0.05).Left-sided UC and severe UC were more common in VEO-UC group(all P ＜ 0.05),while pancolitis and mild UC were more common in LO-UC group (all P ＜ 0.05).The incidence of intestinal perforation in the VEO-UC group was significantly higher than that in the LO-UC group (P ＜0.05).The incidence of surgical rate,intestinal obstruction,and intestinal perforation in the LO-CD group were significantly higher than those in the LO-UC group (all P ＜ 0.05).Conclusions Compared between VEO-IBD and LO-IBD,VEO-IBD patients are more severe,with perianal lesions more common,and the incidence of intestinal perforation is higher.

Objective@#To investigate the clinical features, treatment strategies and long term outcomes of children with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis.@*Methods@#The data of clinical features, auxiliary examinations, treatments and prognosis in children with anti-NMDAR encephalitis in Xiangya Hospital of Central South University from March 2014 to October 2017 were collected and retrospectively analyzed. A total of 71 patients were enrolled, including 33 males and 38 females. The youngest age of onset was 4 months old, and the age of onset was (9±4) years. The first-line immunotherapy treatment for anti-NMDAR encephalitis was short course corticosteroid (high-dose impulse therapy and oral maintenance therapy for 1 month in acute period) and (or) immunoglobulin. The clinical evaluation was performed 2 weeks after first-line immunotherapy treatment. The second-line immunotherapy treatment, including rituximab and (or) cyclophosphamide, would be started if the symptoms did not improve significantly and the modified Rankin scale (mRS) score ≥3. All patients were followed up and evaluated for prognosis. T-test, Mann-Whitney U, Chi square test and Fisher′s exact probability method were used for comparison between good outcome group and poor outcome group, first-line immunotherapy group and first-line immunotherapy combined with second-line immunotherapy group.@*Results@#The more common clinical manifestations were psychiatric symptoms (n=61, 86%), dyskinesia (n=55, 77%) and convulsions (n=51, 72%). Two cases (3%) had tumors. Electroencephalogram (EEG), cerebro-spinal fluid (CSF) and brain magnetic resonance imaging (MRI) studies were abnormal in 83% (59/71), 39% (27/69) and 38% (27/71) patients, respectively. For the treatment regimens, all the 71 patients underwent first-line immunotherapy, resulting in improvement within 14 days in 40 cases (56%), and 1 case (1%) died. The rest 30 cases (42%) received second-line immunotherapy. The patients were followed up for 5.0-41.8 months, with a median of 19.3 months. At the last follow-up, 49 cases (69%) recovered completely, 15 cases (21%) had mild disability, 6 cases (8%) had severe disability, 1 case (1%) died and 3 cases (4%) had relapse. There were significant differences between the groups with good prognosis and poor prognosis on admission to pediatric intensive care unit (PICU) and consciousness disorder (10/64 vs. 5/7, 39/64 vs. 7/7, P=0.047, 0.004). There were significant differences between first-line immunotherapy group and the first-line combined second-line immunotherapy group on admission to PICU, consciousness disorder, sleep disorder and first mRS score (12% (5/41) vs. 33% (10/30), 44% (18/41) vs. 93% (28/30), 56% (23/41) vs. 90% (27/30), 3 (1-5) vs. 4 (3-5), respectively; χ2=4.645, 18.555, 9.560, Z=5.184, P=0.031, <0.01, 0.002, <0.01, respectively).@*Conclusions@#Anti-NMDAR encephalitis can occur in all ages of children. The most common clinical manifestations are psychotic symptoms, dyskinesia and convulsions. Paraneoplastic cases are less common in children. Immunotherapy is effective. The second-line immunotherapy should be given after the failure of first-line therapy (mRS score≥3).
RESUMEN
Objective@#To investigate the antibiotic resistance of Helicobacter pylori(Hp) isolates cultured from endoscopic gastric mucosal samples and influencing factors for antibiotic resistance in children.@*Methods@#From April 2013 to February 2016, Hp cultured from mucosa samples of the gastric antrum and the body of stomach was investigated in 246 patients with 13C breath test positive examined by gastroscopy.Resistance to Amoxicillin, Clarithromycin, Metronidazole, Tetracycline was tested for Hp by using E-test.The clinical data were collected from the patients, and the relationship among age, gender, endoscopic diagnosis, histological performance, eradication number factors and antibiotic resistance rate were analyzed.@*Results@#Of 246 specimens, 174 cases (70.7%) were positive.The overall antibiotic resistance rates of isolates obtained were 96.55% (168/174 cases), 57.47% (100/174 cases), 4.02% (7/174 cases), 1.15%(2/174 cases) with respect to Clarithromycin, Metronidazole, Tetracycline and Amoxicillin.An antibiotic resistance rate was 43.10% (75/174 strains), among which the Clarithromycin resistance rate was 93.33% (70/75 strains), and the Metronidazole resistance rate was 6.67% (5/75 strains). Double resistance rate was of 54.02%(94/174 strains), among which the resistances rate of Clarithromycin+ Metronidazole was 52.30%(91/94 strains), and the resistances rate of Clarithromycin+ Tetracycline was 1.72%(3/94 strains). Triple resistance rate of Clarithromycin+ Metronidazole+ Tetracycline was 1.15%(2/174 strains). Quadruple resistance rate of Clarithromycin+ Metronidazole+ Amoxicillin+ Tetracycline was 1.15%(2/174 strains). Factor analysis showed that the resistance rate of Clarithromycin in children who had failed in eradication therapy [98.7%(148/150 cases)] was higher than that in children who had not undergone eradication therapy [83.3%(20/24 cases)], and the difference was statistically significant(χ2=14.610, P<0.05). There was no significant difference in the relationship between Hp resistance to Metronidazole and Clarithromycin and the age, gender, endoscopic diagnosis and histological manifestations(all P>0.05).@*Conclusions@#Hp resistance rate to Clarithromycin, Metronidazole is very high in children, but it is relatively low to Amoxicillin and Tetracycline, and multiple antibiotic resistance is at high prevalence.

Objective To investigate the clinical features,diagnosis and treatment of febrile infection-related epilepsy syndrome (FIRES).Methods The clinical data of 12 children with FIRES admitted to Xiangya Hospital of Central South University from 2015 to 2018 were retrospectively analyzed.The basic information,clinical manifestations,electroencephalogram,imaging examination,treatment and prognosis were analyzed.Results Of the 12 patients,7 were male and 5 were female.The age of onset was (7.0 ± 3.7)years (1.3 year to 13 years).The average hospitalization time (34-86 days,median 52 days).Twelve patients were healthy before the disease,and had fever before convulsion.The interval between fever and seizure was (3.5 ± 1.7) days (1-7 days).The status epilepticus and consciousness deficit were the main clinical manifestations.The electrogram of 8 patients showed status epilepticus when admitted.12 patients had disturbance of consciousness;the acute episodes were focal seizures (100％,12/12) and generalized tonic-clonic seizures (41.7％,5/12).All patients used 3-5 antiepileptic drugs (median 4),all treated with hormones and gamma globulin.4 patients with ketogenic diet (KD) were treated within 2 weeks of onset,and the average duration from onset to electroencephalogram (EEG) improvement was (19.2 ± 5.0)days.In 8 patients who did not use KD within 2 weeks of onset,the average duration from onset to EEG improvement was (29.9 ± 9.6) days.Conclusions FIRES is more common in normal children with school age.The main manifestation is refractory status epilepticus in the days after acute fever,focal episodes of seizures,anti-epileptic drug resistance.Early initiation of KD produces a favorable prognosis.
RESUMEN
From November, 2010 to February, 2018, 11 children with variants of Guillain-Barré syndrome (GBS) were treated in Xiangya Hospital of Central South University. Clinical manifestations included cranial nerve involvement in 9 cases, limb weakness in 9 cases, ataxia in 8 cases, abnormal sensation in 7 cases, weakened or disappeared tendon reflex in all cases, albuminocytologic dissociation of cerebrospinal fluid in 6 cases, and neurogenic changes in electromyography in 8 cases. Immune globulin and steroids were given to 5 cases and 1 case, respectively, while the combination of immune globulin with steroids was given to 1 case, and symptomatic treatment was given to 4 cases. All treatments were effective, remaining no apparent side effect for nervous system. The diagnosis of GBS variants was based on clinical manifestation. Patients who had cranial nerve involvement, ataxia and weakened or disappeared tendon reflex should be paid attention. Albuminocytologic dissociation of cerebrospinal fluid and electromyography were helpful to diagnosis. GBS variants were self-limited disease. Immunotherapy can ease the patients' critical condition.
