Review
AIM
A systematic literature review of intravenous immunoglobulin (IVIG) treatment of paediatric neurological conditions was performed to summarize the evidence, provide recommendations, and suggest future research.
METHOD
A MEDLINE search for articles reporting on IVIG treatment of paediatric neuroinflammatory, neurodevelopmental, and neurodegenerative conditions published before September 2015, excluding single case reports and those not in English. Owing to heterogeneous outcome measures, meta-analysis was not possible. Findings were combined and evidence graded.
RESULTS
Sixty-five studies were analysed. IVIG reduces recovery time in Guillain-Barré syndrome (grade B). IVIG is as effective as corticosteroids in chronic inflammatory demyelinating polyradiculoneuropathy (grade C), and as effective as tacrolimus in Rasmussen syndrome (grade C). IVIG improves recovery in acute disseminated encephalomyelitis (grade C), reduces mortality in acute encephalitis syndrome with myocarditis (grade C), and improves function and stabilizes disease in myasthenia gravis (grade C). IVIG improves outcome in N-methyl-d-aspartate receptor encephalitis (grade C) and opsoclonus-myoclonus syndrome (grade C), reduces cataplexy symptoms in narcolepsy (grade C), speeds recovery in Sydenham chorea (grade C), reduces tics in selected cases of Tourette syndrome (grade D), and improves symptoms in paediatric autoimmune neuropsychiatric disorder associated with streptococcal infection (grade B).
INTERPRETATION
IVIG is a useful therapy in selected neurological conditions. Well-designed, prospective, multi-centre studies with standardized outcome measures are required to compare treatments.

Review
BACKGROUND
Understanding of chronic sequelae development after Campylobacter infection is limited. The objective of the study was to determine via systematic review and meta-analysis the proportion of Campylobacter cases that develop chronic sequelae.
METHODS
A systematic review of English language articles published prior to July 2011 located using Pubmed, Agricola, CabDirect, and Food Safety and Technology Abstracts. Observational studies reporting the number of Campylobacter cases that developed reactive arthritis (ReA), Reiter's syndrome (RS), haemolytic uraemic syndrome (HUS), irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) ,Guillain Barré syndrome (GBS) or Miller Fisher syndrome (MFS) were included. Data extraction through independent extraction of articles by four reviewers (two per article). Random effects meta-analysis was performed and heterogeneity was assessed using the I(2) value. Meta-regression was used to explore the influence of study level variables on heterogeneity.
RESULTS
A total of 31 studies were identified; 20 reported on ReA, 2 reported on RS, 9 reported on IBS, 3 studies reported on IBD, 8 reported on GBS, 1 reported on MFS and 3 reported on HUS. The proportion of Campylobacter cases that developed ReA was 2.86% (95% CI 1.40% - 5.61%, I(2) = 97.7%), irritable bowel syndrome was 4.01% (95% CI 1.41% - 10.88%, I(2) = 99.2%). Guillain Barré syndrome was 0.07% (95% CI 0.03% - 0.15%, I(2) = 72.7%).
CONCLUSIONS
A significant number of Campylobacter cases develop a chronic sequela. However, results should be interpreted with caution due to the high heterogeneity.

Review
AIM
The cognitive and psychiatric aspects of adult movement disorders are well established, but specific behavioural profiles for paediatric movement disorders have not been delineated. Knowledge of non-motor phenotypes may guide treatment and determine which symptoms are suggestive of a specific movement disorder and which indicate medication effects.
METHOD
The goal of this review is to outline the known cognitive and psychiatric symptoms associated with paediatric movement disorders. We used a systematic approach, via PubMed, and reviewed over 400 abstracts of studies of selected disorders, of which 88 papers reporting paediatric non-motor symptoms are summarized.
RESULTS
Obsessive-compulsive disorder was manifest in children with paediatric autoimmune neuropsychiatric disorders associated with streptococcal infections and Sydenham chorea. Children with opsoclonus-myoclonus syndrome had, for the most part, cognitive and behavioural problems, and attention-deficit-hyperactivity disorder was reported as a major comorbidity in Tourette syndrome, stereotypies, and restless legs syndrome. Symptoms of depression and anxiety were more frequent in individuals with idiopathic dystonia. Affective disorders were suggestive of Wilson disease. Cognitive decline was common in children with juvenile Huntington disease. A limitation of this review was the lack of systematic assessment in paediatric movement disorders for evaluation and uniform definitions.
INTERPRETATION
Although the literature in non-motor phenomena is still emerging, recognition of salient cognitive and psychiatric phenomena may facilitate management of paediatric movement disorders.

Review
Strabismus can hinder an individual's ability to perform daily functions and negatively affect their well-being. I examine the impact strabismus has on psychosocial health and quality of life in children and adults and evaluate the challenges confronted by parents of children with strabismus. Numerous misconceptions exist regarding the impact strabismus has on overall health. Negative attitudes persist toward those affected, resulting in difficulties with self-image. Individuals with strabismus are at increased risk for both visual system and psychiatric disorders. Misinformation regarding available treatment options for children and adults with strabismus continues to exist, resulting in decreased access to care. Improved education of health care providers can increase appropriate referrals and initiation of treatment. Treatment of strabismus is not merely cosmetic and has the potential to improve psychosocial health and quality of life for children and adults with and without diplopia.

BACKGROUND
Neuroblastoma is the most common malignancy in children younger than seven years of age and is the most frequent extracranial solid tumor that occurs in childhood. While opsoclonus-myoclonus syndrome (OMS), a paraneoplastic neurologic syndrome, affects 2-3% of children with neuroblastoma, and the percentage of mediastinal localization of the tumor is 49%. The objective of this study was to identify and characterize features of the OMS syndrome and treatments of mediastinal and non-mediastinal neuroblastoma associated with OMS.
METHODS
A systematic review of the literature was performed using PubMed, Medline, Web of Science, Embase and Cochrane. The search has no limit on date with the last search done on Dec 31, 2020. There is no publication restrictions or study design filters applied in the search.
RESULTS
Fifty-five out of 242 papers were identified and met our study eligibility. There were 77 cases found (28 cases had Mediastinal neuroblastoma, and 49 cases had non-mediastinal neuroblastoma). Data from trials showed that cases with mediastinal neuroblastoma who seemed to have undergone less treatment for OMS [rate ratio (RR) 0.41 (95% CI: 0.22-0.76)] had resulted in decreasing persistent neurologic symptoms [RR 0.31 (95% CI: 0.10-0.96)].
CONCLUSIONS
Children who have OMS and mediastinal neuroblastoma may be associated with more favorable clinical and biological characteristics and better outcomes than children who have OMS and non-mediastinal neuroblastoma, and they are more likely to present with a single neurological symptom at first. The OMS in mediastinal neuroblastoma might also be treated effectively through resection of the tumor followed by appropriate radiotherapy and chemotherapy, and no long-term treatments of OMS is indicated.

Meta-Analysis
OBJECTIVE
Dexmedetomidine is a medication that has analgesic, sedative, and anti-anxiety properties. In the clinical, it is often used to prevent common complications associated with strabismus surgery, including postoperative delirium, postoperative nausea and vomiting, postoperative pain, and oculocardiac reflex. However, its effectiveness and side effects of the present studies are different. The sample sizes of the present studies on the prevention of complications of dexmedetomidine are small. Therefore, this study evaluates the efficacy of dexmedetomidine in preventing anesthesia-related complications in strabismus surgery through a systematic review and meta-analysis.
METHODS
Literature was retrieved from 10 commonly used databases and randomized controlled trials published up to May 2022 were sought. The included studies compared the intervention effects of dexmedetomidine versus placebo on anesthesia-related complications in surgery. The occurrence rates of postoperative delirium, postoperative nausea and vomiting, postoperative pain, and oculocardiac reflex in patients undergoing strabismus surgery were evaluated. Statistical analyses and forest plots were generated using Review Manager and STATA software. Binary outcomes were measured using relative risk (RR) with a 95% confidence interval for each outcome. The Cochrane risk of bias tool was used to assess the bias and risk in the studies that met the inclusion criteria.
RESULTS
A total of 13 articles were ultimately included in the analysis, comprising 1,018 patients who underwent strabismus surgery. The dexmedetomidine group, compared to the placebo group, demonstrated significant reductions in the incidence of postoperative delirium (RR = 0.73, P = 0.001), severe postoperative delirium (RR = 0.45, P = 0.005), postoperative nausea and vomiting (RR = 0.48, P < 0.0001), and the need for supplemental analgesia postoperatively (RR = 0.60, P = 0.004). Additionally, subgroup analysis revealed that intravenous administration of dexmedetomidine significantly reduced the incidence of oculocardiac reflex (RR = 0.50, P = 0.001). In contrast, intranasal administration of dexmedetomidine did not have a significant effect on the incidence of oculocardiac reflex (RR = 1.22, P = 0.15). There was a significant difference between the subgroups (P = 0.0005, I2 = 91.7%).
CONCLUSION
Among patients undergoing strabismus surgery, the use of dexmedetomidine can alleviate postoperative delirium and reduce the incidence of postoperative nausea and vomiting, as well as postoperative pain. Moreover, intravenous administration of dexmedetomidine can lower the occurrence rate of the oculocardiac reflex.

BACKGROUND
COVID-19 (CoranaVirus disease 2019) is an ongoing infectious disease caused by the RNA SARS-CoV-2 virus (Severe Acute Respiratory Syndrome CoronaVirus-2). The virus mainly causes respiratory symptoms, but neurological symptoms have also been reported to be part of the clinical manifestations of the disease. The aim of this study was to systematically review Miller fisher syndrome (MFS) published cases, in the context of COVID-19 infection or vaccination.
METHODS
A systematic literature review on Medline was performed. A total of 21 papers were included in the present review.
RESULTS
Twenty-two MFS cases (77% males) were identified, 14 related to COVID-19 infection and 8 to vaccination against COVID-19. The median age of the adult patients was 50 years (interquartile range 36-63 years). Sixteen patients (73%) had the classic triad of MFS (ophthalmoplegia, ataxia, areflexia), four (18%) had acute ophthalmoplegia and one other characteristic symptom and two patients (9%) had only one other characteristic symptom, but they tested positive for GQ1b antibodies. Nine (41%) patients had positive GQ1b antibodies and were classified as "definite" MFS. Albuminocytologic dissociation was found in half of the cases. The outcome was favourable in the majority of cases (86%) whereas one patient, despite the initial improvement, died because of a cardiac arrest, after cardiac arrythmia.
CONCLUSIONS
MFS after COVID-19 infection/vaccination was found to have the typical epidemiological characteristics of classic MFS; being rare, occurring more often after infection than vaccination, affecting mainly middle-aged males usually within 3 weeks after the event and having an excellent prognosis after treatment with IVIG or even with no treatment at all. We found no evidence that MFS after COVID-19 infection was different from MFS after COVID-19 vaccination, although the former tended to occur earlier.

Depression and apathy can be significant problems in progressive supranuclear palsy (PSP). Using PRISMA guidelines, this systematic review examined prevalence estimates for depression and apathy in PSP, and, how different methods of definition may influence results. 29 studies meeting inclusion/exclusion criteria were identified: 12 on depression, 9 on apathy, and 8 on both. Studies were stratified according to whether a diagnostic criteria, rating scale or screening question methodology was employed. The weighted mean prevalence was 59.7% for depression (sample size = 473) and 58.3% for apathy (sample size = 858). Results for depression using diagnostic criteria or rating scales were similar whereas screening questions were associated with considerable inconsistency. Depression prevalence appeared to be influenced by apathy but not somatic symptoms. Most apathy studies relied only on a screening question method. Depression and apathy are common in PSP but there is a need for consensus on how they are defined (both tools and cut-off scores). In particular, more studies probing apathy in greater detail than a simple screening question are required.

Comparative Study Meta-Analysis
To compare outcomes of diclofenac versus dexamethasone in patients after strabismus surgery. A systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search was conducted on MEDLINE, EMBASE, EMCARE, CINAHL, and the Cochrane Central Register of Controlled Trials (CENTRAL). All randomized controlled trials (RCTs) comparing the outcomes of diclofenac versus dexamethasone poststrabismus surgery were included. An extraction spreadsheet for data collection and Review Manager 5.3 were used for data analysis based on the fixed and random effects models. Discomfort, inflammation, chemosis, conjunctival gap, and intraocular pressure (IOP) were primary outcome measures. Secondary outcomes included conjunctival congestion and injection, discharge, and drop intolerance. Fixed and random effects models were used for the analysis. Five RCTs enrolling 248 subjects were enrolled. At week 2 postoperatively, there was a significant difference favoring diclofenac over dexamethasone in terms of discomfort (mean difference [MD] = -0.37, = 0.02), conjunctival inflammation (MD = -0.16, = 0.02), conjunctival chemosis (MD = -0.16, = 0.04), and postoperative conjunctival gap (MD = -0.17, = 0.002). In terms of IOP, there were no significant differences. However, no statistically significant differences were noted at weeks 1 and 4 postoperatively. For secondary outcomes, dexamethasone had significantly improved conjunctival congestion; however, diclofenac had significantly less injection at the site of muscle attachments at week 2. No significant difference was noted in terms of discharge and drop intolerance. Diclofenac is comparable to dexamethasone when used following strabismus surgery. However, a significant difference favoring diclofenac in terms of discomfort, inflammation, conjunctival chemosis, and conjunctival gap was only noted at 2 weeks postoperatively. The authors suggest conducting further studies to support the effectiveness of diclofenac as an alternative to corticosteroids following strabismus surgery.

Meta-Analysis Review
OBJECTIVE
To undertake a systematic review and meta-analysis of studies that investigated prognostic factors and survival in patients with progressive supranuclear palsy (PSP) and multiple system atrophy (MSA).
METHODS
Publications of at least 10 patients with a likely or confirmed diagnosis of PSP or MSA were eligible for inclusion. Methodological quality was rated using a modified version of the Quality in Prognostic Studies tool. For frequently examined prognostic factors, HRs derived by univariate and multivariate analysis were pooled in separate subgroups; other results were synthesised narratively and HRs could not be reported here.
RESULTS
Thirty-seven studies presenting findings on 6193 patients (1911 PSP, 4282 MSA) fulfilled the inclusion criteria. We identified the following variables as unfavourable predictors of survival. In PSP, PSP-Richardson's phenotype (univariate HR 2.53; 95% CI 1.69 to 3.78), early dysphagia and early cognitive symptoms. In MSA, severe dysautonomia and early development of combined autonomic and motor features but not MSA phenotype (multivariate HR 1.22; 95% CI 0.83 to 1.80).In PSP and MSA, survival was predicted by early falls (multivariate HR 2.32; 95% CI 1.94 to 2.77), the Neuroprotection and Natural History in Parkinson Plus Syndromes Parkinson Plus Score and the Clinical Global Impression Disease Severity Score but not sex (multivariate HR 0.93; 95% CI 0.67 to 1.28). There was conflicting evidence regarding the prognostic effect of age at onset and stridor.
CONCLUSION
Several clinical variables were strongly associated with shorter survival in PSP and MSA. Results on most prognostic factors were consistent across methodologically diverse studies; however, the lack of commonality of prognostic factors investigated is a significant limitation.
