Objective To systematic review the methodological quality of guidelines for Guillain-Barré syndrome (GBS) in children, to provide a reference for clinical evidence-based medicine. Methods Guidelines concerning GBS were electronically retrieved from PubMed, EMbase, CBM, Wanfang data, CNKI and Vip. The guide databases includes major medical institutions and industry sites such as NGC, GIN, TRIP , CDC, IDSA, AAP, WHO, Chinese Health and Family Planning Committee website, library of clinical guidelines China and Chinese clinical guidelines for collaboration. All the data were searched from inception of the database or network to Oct. 2013. Two reviews independently screened literature according to the inclusion and exclusion criteria, and assessed the quality of guideline using the AGREEⅡ. Intraclass correlation coefficient (ICC) was used to examine the conformance of the raters' evaluation scores. Results A total of 5 guidelines concerning GBS were included, with a time range from 2003 to 2012, and origins from USA, EU and Canada. The final recommendation levels of the 5 articles were level B. According to the AGREEⅡ, domain 3 and 4 showed the higher scores, and scores were generally low in domain 5. Plasma exchange (PE) and intravenous immuneglobulin (IVIG) showed positive effects on the treatment of GBS. But it was not recommended that combined PE and IVIG. Corticosteroids are also not recommended for GBS treatment. Conclusions The recommendations of medicines for GBS are basically consistent. However, the classification criteria of the levels of evidence and recommendation are still unconsistent and suboptimal. The guidelines on GBS should be improved in“Applicability”in future.

Objective:To analyze the characteristics and prognosis of visual field of Leber hereditary optic neuropathy (LHON) with G11778A mutation.Methods:A retrospective clinical study. Twenty-two (44 eyes) of LHON patients diagnosed with G11778A site mutation by mt-DNA examination from May 2008 to February 2018 in Ophthalmology Department of Dongfang Hospital of Beijing University of Chinese Medicine, were enrolled in this study. All patients underwent best corrected visual acuity (BCVA), visual field and optical coherence tomography (OCT). The BCVA examination was performed using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for record. The thickness of the retinal nerve fiber layer (RNFL) in the 200μm×200μm annular region 1.73 mm outside the optic disc was measured by OCT. At least 7 visual field examinations were performed within one month before and after 2, 4, 8, 12, 18, 24 and 30 months of the course of disease by using Octopus 101 perimetry. Among 44 eyes, 27 eyes were detected with G2 procedure (G2 group) and 17 eyes were detected with LVC procedure (LVC group). The mean field defect (MD) and mean optical sensitivity (MS) were used as the main outcome indexes. According to the onset age, the patients were further divided into the ≤14 years old group and>14 years old group. There was a significant difference in initial logMAR BCVA between the G2 group and LVC group ( t=4.994, P=0.000), but there was no significant difference in gender ( χ2=1.896, P=0.169) and age ( t=0.337, P=0.708) between the two groups. Independent sample t test was used for comparison between groups, paired t test was used for comparison within groups, and one-way analysis of variance was used for comparison between groups. The statistical data were compared by χ2 test. Results:In the G2 group, the MD value of the subgroup of children (≤14 years old) decreased gradually during the follow-up period, and the MD value since 18 months after onset was significantly lower than the value of 2 months after onset ( t=3.813, 4.590, 5.033; P=0.002, 0.001, 0.000). No obvious visual field index changes were seen in other subgroups ( P>0.05). The central scotoma was the most common type of visual field defect in the early stage, and the diffuse defect was the most common type of visual field defect in the late stage. There was a significant difference in the types of visual field distribution between the early and late stage in G2 group ( χ2=17.414, P=0.015). There was no significant difference in the type of visual field distribution between the early and late stage in LVC group ( χ2=4.541, P=0.474). The MD value in the G2 group remained stable within 8 months after onset, but significantly improved after 18 months after onset ( t=2.100, 3.217, 3.566; P=0.046, 0.003, 0.001). The MS in the LVC group did not significantly improve during follow-up ( P>0.05). The average visual acuity of the G2 group was significantly improved from 12 months ( t=3.039, 3.678, 4.264, 5.078; P=0.008, 0.002, 0.001, 0.000). The visual acuity of the eyes in the G2 group was better than that of the LVC group during all follow-up periods ( P≤0.05). The RNFL thickness of all patients continued to decrease after onset, but the RNFL thickness was significantly higher at 4, 8, 18, 24, 30 months in the G2 group than those in the LVC group ( t=2.471, 2.269, 2.474, 2.509, 2.782; P=0.018, 0.028, 0.017, 0.016, 0.008). Conclusions:The main types of visual field defect of LHON with G11778A mutation are the central scotoma in the early stage, while the diffuse defect and central scotoma are both very common in the later stage. The visual field of LHON patients examined by G2 procedure is significantly improved during the follow-up, as well as the visual acuity improved significantly, and the visual field improvement in younger cases (≤14 years old) is better than that of older cases (>14 years old), but the visual field of the LVC procedure cases did not improve during follow-up.

OBJECTIVE:To systematically review the related evidence-based guidelines of purulent meningitis in children,and to provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed,EMBase,CBM,Wanfang Data-base,CJFD and VIP,NGC,GIN,TRIP and websites of domestic and international medical associations and industry bodies,the treatment guidelines about purulent meningitis in children were collected. Evidence-based evaluation was performed after data extrac-tion and quality evaluation. RESULTS:Finally 3 guidelines were enrolled in total,with development time ranging from 2004 to 2012,from USA,Britain and Australia,respectively. All of the recommendations were level B,scope and purpose and clarityshowed the higher scores in AGREEⅡ,more than 70%,and applicability showed generally low scores. Penicillin and cefotaxi-me were recommended in purulent meningitis of neonates,and vancomycin combined with cefotaxime or ceftriaxone were recom-mended for infants and children(it was combined with vancomycin when Streptococcus pneumoniae infection was suspected). The dose and duration of each guideline were certain different,and the period of treatment should be longer in neonates. In addition, the glucocorticoid was recommended in all guidelines. CONCLUSIONS:The recommendations of medicines for the treatment of pu-rulent meningitis are basically unanimous,with no regional difference,but there are some differences about dose and the course of treatment. In addition,the classification criteria of the levels of evidence and recommendation are still suboptimal,which needs fur-ther improvement. And guidelines on purulent meningitis should be improved inrigourandapplicabilityin future.
