Review
BACKGROUND
Preliminary data suggest that patients with COVID-19 may experience psychiatric symptoms, including psychosis. We systematically reviewed the literature to evaluate the concurrence of new-onset psychosis or exacerbation of clinically stable psychosis through case reports and case series.
METHODS
Six databases were searched, followed by an electronic and manual search of the relevant articles. Studies were identified using predetermined eligibility criteria. We evaluated the demographic characteristics, clinical history, course of illness, management, and prognosis of the patients in these studies.
RESULTS
Case reports and case series, altogether consisting of 57 unique cases were included. The mean patient age for onset of psychotic symptoms was 43.4 years for men and 40.3 years for women. About 69% of patients had no prior history of psychiatric disorders. Most patients had mild COVID-19-related symptoms, with only 15 (26.3%) presenting with moderate to severe COVID-19-related disease and complications. The most commonly reported psychotic symptoms were delusions and hallucinations. Patients with psychotic symptoms were treated with antipsychotics, benzodiazepines, valproic acid, and electroconvulsive treatment. In 36 cases, psychotic symptoms resolved completely or improved significantly. Ten cases had partial improvement with residual psychotic symptoms, and one patient died due to cardiac arrest.
CONCLUSION
Most patients responded to a low-to-moderate dose of antipsychotics with a quick recovery. However, the residual psychiatric symptoms highlight the need for careful monitoring and longer follow-up. Clinicians should be mindful of the occurrence of psychosis due to COVID-19 infection in a subset of COVID-19 patients that can be misdiagnosed as a psychotic disorder alone.

Meta-Analysis
BACKGROUND
Epilepsy is a long-term recurrent chronic brain disease that can cause significant emotional burden to the patient and their family, as well as huge economic costs to society. Timely and accurate diagnosis of epilepsy, together with early and standardized treatments can effectively control seizures and restore the patient's quality of life and reduce the economic burden. This meta-analysis examined the efficacy of lamotrigine administration in patients with epilepsy.
METHODS
A literature search was performed in the PubMed, Embase, and OVID-Medline databases to identify articles related to epilepsy and lamotrigine that were published from the establishment of the database to April 2021. The keywords used for the literature search included "epilepsy", "sodium valproate", "lamotrigine", "effectiveness", and "therapeutic effect". It uses Cochrane review manual 5.3 to evaluate the quality of the included literature and review manager 5.3 software for meta-analysis.
RESULTS
A total of 9 studies involving 1,864 patients with epilepsy were included in this meta-analysis. The results revealed that, after treatment failure with the first drug of valproic acid, the total effective rate of lamotrigine treatment had an odds ratio (OR) of 2.21 with a 95% confidence interval (CI) of 1.15 to 4.27 (Z=2.37; P=0.02). The total adverse reaction rate (OR =0.70; 95% CI: 0.55 to 0.88; Z=2.98; P=0.003) and the improvement rate of epilepsy associated with lamotrigine treatment (OR =4.22; 95% CI: 1.00 to 17.84; Z=1.96; P=0.05) were all significantly higher than that of other drug treatments.
DISCUSSION
A total of 9 articles were included in this meta-analysis to examine the efficacy of lamotrigine in the treatment of epilepsy. The clinical efficacy of lamotrigine addition therapy was found to be superior to lamotrigine replacement therapy, and the incidence of adverse reactions was lower than that of lamotrigine replacement therapy. However, due to the low methodological quality of the included literatures, this conclusion should be further verified using large sample and high-quality randomized double-blinded experiments.

Academic Emergency Medicine : Official... Sep 2022This review was designated to evaluate the efficacy of parenteral ketorolac in treating acute migraine headache. (Meta-Analysis)
Meta-Analysis
OBJECTIVES
This review was designated to evaluate the efficacy of parenteral ketorolac in treating acute migraine headache.
METHODS
We searched databases Cochrane Central Register of Controlled Trials (CENTRAL), Medline, and Google Scholar up to January 2021 and identified randomized controlled trials comparing ketorolac to any other medications in treating patients presenting with migraine headache.
RESULTS
Thirteen trials were included in our review, comprising 944 participants. We derived seven comparisons: ketorolac versus phenothiazines, metoclopramide, sumatriptan, dexamethasone, sodium valproate, caffeine, and diclofenac. There were no significant differences in the reduction of pain intensity at 1 h under the comparisons between ketorolac and phenothiazines (standard mean difference [SMD] = 0.09, p = 0.74) or metoclopramide (SMD = 0.02, p = 0.95). We also found no difference in the outcome recurrence of headache (ketorolac vs. phenothiazines (risk ratio [RR] =0.98, p = 0.97)], ability to return to work or usual activity (ketorolac vs. metoclopramide [RR = 0.64, p = 0.13]), need for rescue medication (ketorolac vs. phenothiazines [RR = 1.72, p = 0.27], ketorolac vs. metoclopramide [RR 2.20, p = 0.18]), and frequency of adverse effects (ketorolac vs. metoclopramide [RR = 1.07, p = 0.82]). Limited trials suggested that ketorolac offered better pain relief at 1 h compared to sumatriptan and dexamethasone; had lesser frequency of adverse effects than phenothiazines; and was superior to sodium valproate in terms of reduction of pain intensity at 1 h, need for rescue medication, and sustained headache freedom within 24 h.
CONCLUSIONS
Ketorolac may have similar efficacy to phenothiazines and metoclopramide in treating acute migraine headache. Ketorolac may also offer better pain control than sumatriptan, dexamethasone, and sodium valproate. However, given the lack of evidence due to inadequate number of trials available, future studies are warranted.

BACKGROUND
Epimutations secondary to gene-environment interactions have a key role in the pathophysiology of major psychiatric disorders. and evidence suggest that mood stabilizers can potentially reverse epigenetic deregulations found in patients with schizophrenia or mood disorders through mechanisms that are not yet fully understood. However, their activity on epigenetic processes has made them a research target for therapeutic approaches.
METHODS
We conducted a comprehensive literature search of PubMed and EMBASE for studies investigating the specific epigenetic changes induced by non-antipsychotic mood stabilizers (valproate, lithium, lamotrigine, and carbamazepine) in animal models, human cell lines, or patients with schizophrenia, bipolar disorder, or major depressive disorder. Each paper was reviewed for the nature of research, the species and tissue examined, sample size, mood stabilizer, targeted gene, epigenetic changes found, and associated psychiatric disorder. Every article was appraised for quality using a modified published process and those who met a quality score of moderate or high were included.
RESULTS
A total of 2,429 records were identified; 1,956 records remained after duplicates were removed and were screened title, abstract and keywords; 129 records were selected for full-text screening and a remaining of 38 articles were included in the qualitative synthesis. Valproate and lithium were found to induce broader epigenetic changes through different mechanisms, mainly DNA demethylation and histones acetylation. There was less literature and hence smaller effects attributable to lamotrigine and carbamazepine could be associated overall with the small number of studies on these agents. Findings were congruent across sample types.
CONCLUSIONS
An advanced understanding of the specific epigenetic changes induced by classic mood stabilizers in patients with major psychiatric disorders will facilitate personalized interventions. Further related drug discovery should target the induction of selective chromatin remodeling and gene-specific expression effects.

Review
PURPOSE
This study intends to assess the reference range of lamotrigine concentration for treating childhood epilepsy.
METHODS
PubMed, Ovid-Embase, The Cochrane Library, CNKI, WanFang data and VIP databases were searched from database inception to January 2022. RCT, cohort study, case-control study, cross-sectional study that estimated the reference range of lamotrigine for children epilepsy treatment were included. The data extracted included basic information, statistical methods, data type, and results of reference range. Descriptive analysis was performed for them.
RESULTS
8 studies were included and estimated the reference range, and all of them were calculated based on efficacy data and/or concentration data. Statistical methods including ROC curve, concentration-effect curve, mean ± standard deviation, 95% confidence interval and percentile interval were utilized. For lamotrigine monotherapy, the lower limits ranged from 2.06 mg/L to 3.99 mg/L, and the upper limits ranged from 8.43 mg/L to 9.08 mg/L, showing basic consistency. However, for lamotrigine concomitant with valproate, the lower limits ranged from 2.00 mg/L to 8.00 mg/L, and the upper limit was 11.50 mg/L, for lamotrigine concomitant with other antiepileptics, the lower limits ranged from 1.00 mg/L to 3.09 mg/L, and the upper limits varied from 5.90 mg/L to 16.24 mg/L, indicating inconsistency.
CONCLUSION
Several studies have estimated the reference range of lamotrigine for childhood epilepsy, while controversy exist and no studies have determined the upper limit of the range based on safety data. To establish the optimal reference range, further high-quality studies are necessary that consider both efficacy and safety data.

Meta-Analysis
PURPOSE
Antiseizure medications (ASM) have long been examined for their potential to induce thyroid dysfunction. The aim of this systematic review and meta-analysis was to assess the prevalence of thyroid disease in children up to 16 years receiving monotherapy with valproate (VPA), carbamazepine (CBZ) and levetiracetam (LEV).
METHODS
PubMed/MEDLINE, Cochrane/CENTRAL databases and the gray literature were searched to identify observational studies providing the prevalence of thyroid dysfunction in the target population under VPA, CBZ, or LEV monotherapy schemes. The results were pooled using a random-effects model, and additional subgroup analyses were performed for the three ASM groups.
RESULTS
Fifteen and thirteen studies met inclusion criteria for the qualitative and the quantitative analysis, respectively, with a total of 945 pediatric patients with prevalence data. Only VPA and CBZ were associated with thyroid dysfunction. The overall prevalence of thyroid abnormality was higher in children receiving ASM [odds ratio (OR) 6.82, 95% confidence interval (CI) 3.96-11.75]. In the subgroup analysis, the prevalence of biochemical thyroid abnormality with increased TSH was higher in the VPA (OR 9.54, 95%CI 5.25-17.34) and the CBZ group (OR 4.08, 95%CI 1.84-9.04) compared with controls.
CONCLUSION
This study confirms the higher prevalence of biochemical thyroid abnormality in children under VPA and CBZ monotherapy, whereas no such evidence is present for LEV. In children with a predisposition for thyroid disease, LEV should be considered over VPA and CBZ, if appropriate for seizure type and epilepsy syndrome. More studies are needed to reach a consensus on monitoring and management of thyroid dysfunction in children receiving ASM therapy.

Aggression is a commonly reported problem following traumatic brain injury (TBI). It may present as verbal insults or outbursts, physical assaults, and/or property destruction. Aggressive behavior can fracture relationships and impede participation in treatment as well as a broad range of vocational and social activities, thereby reducing the individual's quality of life. Pharmacological intervention is frequently used to control aggression following TBI. The aim of this systematic review was to critically evaluate the evidence regarding efficacy of pharmacological interventions for aggression following TBI in adults. We reviewed studies in English, available before December 2018. MEDLINE, PubMed, CINAHL, EMBASE, PsycINFO, and CENTRAL databases were searched, with additional searching of key journals, clinical trials registries, and international drug regulators. The primary outcomes of interest were reduction in the severity of aggression and occurrence of harms. The secondary outcomes of interest were changes in quality of life, participation, psychological health (e.g., depression, anxiety), and cognitive function. Evidence quality was assessed using the Cochrane Risk of Bias tool and the Joanna Briggs Institute Critical Appraisal Instruments. Ten studies were identified, including five randomized controlled trials (RCTs) and five case series. There were positive, albeit mixed, findings for the RCTs examining the use of amantadine in reducing irritability ( = 2) and aggression ( = 2). There were some positive findings favoring methylphenidate in reducing anger ( = 1). The evidence for propranolol was weak ( = 1). Individual analysis revealed differential drug response across individuals for both methylphenidate and propranolol. The less rigorous studies administered carbamazepine ( = 2), valproic acid ( = 1), quetiapine ( = 1), and sertraline ( = 1), and all reported reductions in aggression. However, given the lack of a control group, it is difficult to discern treatment effects from natural change over time. This review concludes that a recommendation for use of amantadine to treat aggression and irritability in adults following TBI is appropriate. However, there is a need for further well-designed, adequately powered and controlled studies of pharmacological interventions for aggression following TBI.

BACKGROUND
Seizures are an important palliative symptom, the management of which can be complicated by patients' capacity to swallow oral medications. In this setting, and the wish to avoid intravenous access, subcutaneous infusions may be employed. Options for antiseizure medications that can be provided subcutaneously may be limited. Subcutaneous sodium valproate may be an additional management strategy.
AIM
To evaluate the published experience of subcutaneous valproate use in palliative care, namely with respect to effectiveness and tolerability.
DESIGN
A systematic review was registered (PROSPERO CRD42023453427), conducted and reported according to PRISMA reporting guidelines.
DATA SOURCES
The databases PubMed, EMBASE and Scopus were searched for publications until August 11, 2023.
RESULTS
The searches returned 429 results, of which six fulfilled inclusion criteria. Case series were the most common study design, and most studies included <10 individuals who received subcutaneous sodium valproate. There were three studies that presented results on the utility of subcutaneous sodium valproate for seizure control, which described it to be an effective strategy. One study also described it as an effective treatment for neuropathic pain. The doses were often based on presumed 1:1 oral to subcutaneous conversion ratios. Only one study described a local site adverse reaction, which resolved with a change of administration site.
CONCLUSIONS
There are limited data on the use of subcutaneous sodium valproate in palliative care. However, palliative symptoms for which subcutaneous sodium valproate have been used successfully are seizures and neuropathic pain. The available data have described few adverse effects, supporting its use with an appropriate degree of caution.

Review
INTRODUCTION
Epilepsy is one of the most frequent neurological comorbidities in patients with Down Syndrome (DS). Young patients and adults are the most affected, the latter mostly showing a phenotype labeled as "Late-onset myoclonic epilepsy" (LOMEDS). Status epilepticus (SE) is a life-threatening complication in patients with epilepsy. In this study, we described a non-convulsive SE (NCSE) case in a patient diagnosed with LOMEDS. We also performed a systematic review of the literature on SE diagnosis and treatment in patients with Down Syndrome.
METHODS
Clinical and demographic characteristics of a DS patient diagnosed with NCSE were described. The systematic literature search dissected the diagnostic and therapeutic management of SE in patients with DS. The following databases were used: PubMed, EMBASE, and Google Scholar.
RESULTS
5 DS individuals (4 from the past literature + 1 novel case report) with SE have been identified. The median age at SE onset was 42 years (IQR: 21-60.5 years). The most common SE type was myoclonic SE (MSE), followed by NCSE. Two cases of acute symptomatic etiology were described, whereas a progressive symptomatic etiology was otherwise reported. Ictal EEG recording information was available in two patients who showed generalized spike waves and polyspike and wave discharges. In 3 cases, SE was treated with intravenous antiseizure medications that produced a complete resolution.
CONCLUSION
SE may represent a rare complication in patients with DS. Although no definitive conclusions may be achieved due to the lack of evidence, treatment with valproic acid seems effective, especially in MSE. NCSE management is more challenging. It requires low doses of anesthetics, which should be used cautiously due to the high rate of complications.

Meta-Analysis
BACKGROUND
Current research has found contradictory results on the treatment of magnesium valproate (VPM) in patients with dementia (PwD).
OBJECTIVES
Here, we conducted a meta-analysis to evaluate the efficacy and safety of VPM in the adjuvant treatment of PwD.
PURPOSE
Current research has found contradictory results on the treatment of VPM in PwD. Here, we conducted a meta-analysis to evaluate the efficacy and safety of VPM in the adjuvant treatment of PwD.
METHODS
MEDLINE via PubMed, Cochrane Library, EBSCO, Embase, China National Knowledge (CNKI), and Wan Fang databases were researched to gather relevant data on magnesium valproate assistant therapy for patients with dementia (PwD) by using medical subject headings and term words.
RESULTS
After the final screening, 22 RCT studies (a total of 1899 participants) were included in this meta-analysis, which compared VPM adjuvant treatment with antidementia or psychotropic drug monotherapy. Significant differences were found in the scores on mini-mental state examination (P = .028), Alzheimer disease assessment scale cognitive subscale (P < .05), Bech-Rafaelsen Mania Rating Scale (P < .05), behavioral pathology in Alzheimer disease rating scale (P = .001), activities of daily living (P < .05), and Pittsburgh Sleep Quality Index (P < .05). Besides, the levels of inflammatory factors including IL-1β, IL-6, and TNF-α were significantly lower than those in the monotherapy group (P < .05). While there was no increase in the incidence of adverse events (P = .383), VPM as an assistant therapy is generally well tolerated in PwD.
CONCLUSION
By meta-analysis, evidence was found to support VPM additional used for the treatment of cognitive function, psychiatric symptoms, or disease improvement in PwD. VPM may be a potential drug to aid in the treatment of dementia patients. However, there was lack of enough evidence to classification of dementia severity in our inclusion study. More research is still needed, including clinical trials evaluating VPM as a complementary therapy.
