BACKGROUND
Neuromuscular diseases (NMD) emerged as one of the main side effects of the COVID-19 vaccination. We pooled and summarized the evidence on the clinical features and outcomes of NMD associated with COVID-19 vaccination.
METHODS
We comprehensively searched three databases, Medline, Embase, and Scopus, using the key terms covering "Neuromuscular disease" AND "COVID-19 vaccine", and pooled the individual patient data extracted from the included studies.
RESULTS
A total of 258 NMD cases following COVID-19 have been reported globally, of which 171 cases were Guillain-Barré syndrome (GBS), 40 Parsonage-Turner syndrome (PTS), 22 Myasthenia Gravis (MG), 19 facial nerve palsy (FNP), 5 single fiber neuropathy, and 1 Tolosa-Hunt syndrome. All (100%) SFN patients and 58% of FNP patients were female; in the remaining NMDs, patients were predominantly male, including MG (82%), GBS (63%), and PTS (62.5%). The median time from vaccine to symptom was less than 2 weeks in all groups. Symptoms mainly appeared following the first dose of vector vaccine, but there was no specific pattern for mRNA-based.
CONCLUSION
COVID-19 vaccines might induce some NMDs, mainly in adults. The age distribution and gender characteristics of affected patients may differ based on the NMD type. About two-thirds of the cases probably occur less than 2 weeks after vaccination.

Meta-Analysis Review
BACKGROUND
This meta-analysis evaluated long-term efficacy and safety of cryoballoon ablation (CB) of atrial fibrillation (AF).
METHODS
PubMed, Cochrane Library, and Web of Science were searched until July 31, 2023, for published works investigating efficacy and safety of CB of AF in which mean/median follow-up time was not less than 36 months. Safety was assessed by adverse events. Efficacy was assessed by AF recurrence, defined as any atrial arrhythmias lasting more than 30 s.
RESULTS
A total of 19 clinical studies were included. After an average of 58.1 months of follow-up, the overall AF recurrence rate was about 37%. The predictors of recurrence were duration of AF (HR 1.00; 95% CI [1.00 ∼ 1.01]), early recurrence of atrial fibrillation (HR 3.96; 95%CI [1.12 ∼ 14.02]), left atrial diameter (HR 1.04; 95%CI [1.02 ∼ 1.06]), and persistent AF (HR1.47; 95% CI [1.19 ∼ 1.82]). In terms of safety, the incidence of transient phrenic paralysis (PNP) was the highest, about 3%; followed by vascular complications (about 2%); pseudoaneurysm, permanent PNP, and all-cause death was (about 1%); and pericardial effusion and stroke / TIA was very low.
CONCLUSION
CB is associated with low rates of severe complications and reasonable success rates.

Review
OBJECTIVE
Snakebites, a major health concern in developing countries, affect rural farming communities. Venom, primarily neurotoxin, injected during a snake bite disrupts the nervous system, causing symptoms like muscle weakness, paralysis, altered sensation, and coordination issues. This review focuses on evaluating neurological and neuro-ophthalmological manifestations associated with snakebites.
METHODS
A database search was conducted in EMBASE and PubMed for studies published from 2000 to 2023. The investigation centered on examining neurological and neuro-ophthalmological symptoms and signs, treatment approaches, treatment outcomes, and long-term complications of snake bites.
RESULTS
Neurological and neuro-ophthalmological symptoms were common in both neurotoxic and hemotoxic snake bites, especially in neurotoxic cases. Ptosis was a prevalent manifestation across various snake bites, along with respiratory paralysis, limb weakness, dysphasia, and visual disturbances in some instances. However, most patients improved without residual neurological symptoms after treatment.
CONCLUSIONS
Understanding patterns of neurological manifestations contributes valuable insights for the comprehensive management of snakebite.

Meta-Analysis
STUDY OBJECTIVES
Dual orexin receptor antagonists (DORAs) are emerging treatments for insomnia. This meta-analysis study aimed to assess the safety of FDA-approved DORAs (suvorexant, lemborexant, and daridorexant), focusing on narcolepsy-like symptoms associated with these drugs.
METHODS
Five prominent databases were searched to identify randomized controlled trials (RCTs) on this topic. Primary safety outcomes included treatment-emergent adverse events (TEAEs), treatment-related TEAEs, TEAEs leading to discontinuation, and serious TEAEs. Excessive daytime sleepiness (EDS), sleep paralysis, and hallucinations were categorized as adverse events (AEs)-related narcolepsy-like symptoms.
RESULTS
Eleven RCTs with 7703 patients were included. DORAs were associated with a higher risk of TEAEs (risk ratio [RR], 1.09; 95% confidence interval [CI], 1.03 to 1.15) and treatment-related TEAEs (RR, 1.69; 95% CI: 1.49 to 1.92) when compared to placebo. The DORA group exhibited a significantly higher risk of EDS (RR, 2.15; 95% CI: 1.02 to 4.52) and sleep paralysis (RR, 3.40; 95% CI: 1.18 to 9.80) compared to the placebo group.
CONCLUSION
This meta-analysis achieved a comparative evaluation of the clinical safety and tolerability of FDA-approved DORAs for primary insomnia, specifically focusing on AEs-related narcolepsy-like symptoms. This study contributes to understanding the safety profile of FDA-approved DORAs for treating insomnia.

Review Meta-Analysis
BACKGROUND & AIMS
The authors performed a systematic review of epidemiologic data to understand the prevalence, incidence, etiologies, and hospitalizations related to gastroparesis (GP).
METHODS
Studies of the epidemiology of GP published in all languages, years, and countries from 5 databases in January 2022 were studied using prespecified search strategies.
RESULTS
Thirteen studies (data from 1994 to 2019) were included. All but one study (from the United Kingdom) were based in the United States. Prevalence of definite GP (symptoms plus delayed gastric emptying) ranged from 13.8 to 267.7 per 100,000 adults, and incidence was 1.9-6.3 per 100,000 person-years. The estimated 10-year cumulative incidence of GP in type 1 diabetes (DM) and type 2 DM was 5.2% and 1.0%, respectively. Across studies, GP was more common among female patients and those with DM. Rates of hospitalizations and emergency department visits for GP are increasing, ranging from 2- to 18-fold over approximately 2 decades. Mortality rates for patients with possible or definite GP were higher compared with the general population, with primary causes of death in GP being cardiovascular, respiratory failure, and malignancy. Multiple studies observed improved inpatient mortality over the mid-1990s to late 2000s. Limitations include the case identification in most studies (76.9%) used solely International Classification of Diseases codes or clinical record diagnoses; 2 studies (15.4%) used objective evaluation to diagnose GP. Only 4 studies (30.8%) used non-specialized community databases; the remaining 9 studies used inpatient, emergency department, or disease-specific databases.
CONCLUSIONS
There is a paucity of high-quality, demographically diverse, and population-based studies to accurately describe the epidemiology of GP. Future studies with valid gastric emptying measurement are needed to better characterize the epidemiology and natural history of GP.

SIGNIFICANCE STATEMENT
Several recent studies identified mitochondrial mutations in patients with Gitelman or Fanconi syndrome. Mitochondrial cytopathies are generally not considered in the diagnostic workup of patients with electrolyte disorders. In this systematic review, we investigated the presence of electrolyte disorders in patients with mitochondrial cytopathies to determine the relevance of mitochondrial mutation screening in this population. Our analysis demonstrates that electrolyte disorders are commonly reported in mitochondrial cytopathies, often as presenting symptoms. Consequently, more clinical attention should be raised for mitochondrial disease as cause for disturbances in electrolyte homeostasis. Further prospective cohort studies are required to determine the exact prevalence of electrolyte disorders in mitochondrial cytopathies.
BACKGROUND
Electrolyte reabsorption in the kidney has a high energy demand. Proximal and distal tubular epithelial cells have a high mitochondrial density for energy release. Recently, electrolyte disorders have been reported as the primary presentation of some mitochondrial cytopathies. However, the prevalence and the pathophysiology of electrolyte disturbances in mitochondrial disease are unknown. Therefore, we systematically investigated electrolyte disorders in patients with mitochondrial cytopathies.
METHODS
We searched PubMed, Embase, and Google Scholar for articles on genetically confirmed mitochondrial disease in patients for whom at least one electrolyte is reported. Patients with a known second genetic anomaly were excluded. We evaluated 214 case series and reports (362 patients) as well as nine observational studies. Joanna Briggs Institute criteria were used to evaluate the quality of included studies.
RESULTS
Of 362 reported patients, 289 had an electrolyte disorder, with it being the presenting or main symptom in 38 patients. The average number of different electrolyte abnormalities per patient ranged from 2.4 to 1.0, depending on genotype. Patients with mitochondrial DNA structural variants seemed most affected. Reported pathophysiologic mechanisms included renal tubulopathies and hormonal, gastrointestinal, and iatrogenic causes.
CONCLUSIONS
Mitochondrial diseases should be considered in the evaluation of unexplained electrolyte disorders. Furthermore, clinicians should be aware of electrolyte abnormalities in patients with mitochondrial disease.

Sexual hallucinations are little known, yet often extremely burdening, phenomena. In this systematic review, we summarize what is known about their phenomenology, prevalence, etiopathology, ensuing distress, and treatment options. Sexual hallucinations can be experienced as genital or orgasmic sensations, although other sensory modalities can also be involved. With the notable exception of orgasmic auras in the context of epilepsy, sexual hallucinations tend to be distressing and embarrassing in nature. Our analysis of 79 studies (together describing 390 patients) indicates that sexual hallucinations are more frequent in women than in men, with a sex ratio of 1.4:1, and that they are most prevalent in schizophrenia spectrum disorders, with rates ranging from 1.4% in recently admitted patients to 44% in chronically hospitalized patients. Other underlying conditions include epilepsy, the incubus phenomenon (possibly the most prevalent cause in the general population, associated with sleep paralysis), narcolepsy, and sedative use. As regards the sedative context, we found more medicolegal than purely medical cases, which sadly underlines that not all sexually explicit sensations experienced in anesthesia practice are indeed hallucinations. In the absence of evidence-based treatment protocols for sexual hallucinations, practice-based guidelines tend to focus on the underlying condition. Further research is needed, especially in the fields of substance abuse, posttraumatic stress disorder, and borderline personality disorder, where only anecdotal information on sexual hallucinations is available. Moreover, awareness of sexual hallucinations among health professionals needs to be improved in order to facilitate counseling, diagnosis, and treatment.

Meta-Analysis Review
Transpetrosal approaches are known to be associated with a significant risk of complications, including CSF leak, facial palsy, hearing impairment, venous injury, and/or temporal lobe injury. We aimed to evaluate the morbidity of the standard combined petrosal approach (CPA), defined as a combination of the posterior (retrolabyrinthine) and the anterior petrosal approach. We performed a systematic review and meta-analysis of articles reporting on clinical series of patients operated on for petroclival meningiomas through CPA. Studies that used the terminology "combined petrosal approach" without matching the aforementioned definition were excluded as well as clinical series that included less than 5 patients. A total of 8 studies were included involving 160 patients. The pooled complication rates were 3% (95% CI, 0.5-5.6) for CSF leak, 8.6% (95% CI, 4.1-13.2%) for facial palsy, 8.2% (95% CI, 3.9-12.6%) for hearing impairment, 2.8% (95% CI, 0.9-6.5%) for venous complications, and finally 4.8% (95%, 1.2-8.4%) for temporal lobe injury. Contrary to the general belief, CPA is associated with an acceptable rate of complications, especially when compared to alternative approaches to the petroclival area. In view of the major advantages like shorter trajectory, multiple angles of surgical attack, and early tumor devascularization, CPA remains an important tool in the armamentarium of the skull base surgeon.

Meta-Analysis
Although there was no significant heterogeneity in the meta-publication, sensitivity analyses revealed significant heterogeneity. Overall, the prevalence was higher in women (N = 6, R = 4.6%, 95% CI 3.1%, 6.0%, and I = 99.8%) than in men (N = 6, R = 3.4%, 95% CI 2.0%, 4.7%, and I = 99.6the %); prevalence of type 2 diabetes (N = 9, R = 12.5%, 95% CI 7.7%, 17.3%, and I = 95.4%) was higher than type 1 diabetes (N = 7, R = 8.3%, 95% CI 6.4%, 10.2%, and I = 93.6%); the prevalence of DGP was slightly lower in DM patients aged over 60 years (N = 6, R = 5.5%, 95% CI 3.3%, 7.7%, and I = 99.9%) compared to patients under 60 years of age (N = 12, R = 15.8%, 95% CI 11 15.8%, 95% CI 11.4%, 20.2%, and I = 88.3%). In conclusion, our findings indicate that the combined estimated prevalence of gastroparesis in diabetic patients is 9.3%. However, the sensitivity of the results is high, the robustness is low, and there are significant bias factors. The subgroup analysis revealed that the prevalence of DM-DGP is associated with factors such as gender, diabetes staging, age, and study method.

Effect of intraoperative botulinum toxin injection on delayed gastric emptying and need for endoscopic pyloric intervention following esophagectomy: a systematic review, meta-analysis, and meta-regression analysis.
The aim of this study was to evaluate the effect of intraoperative botulinum toxin (BT) injection on delayed gastric emptying (DGE) and need for endoscopic pyloric intervention (NEPI) following esophagectomy. In compliance with Preferred Reporting Items for Systematic reviews and Meta-Analyses statement standards, a systematic review of studies reporting the outcomes of intraoperative BT injection in patients undergoing esophagectomy for esophageal cancer was conducted. Proportion meta-analysis model was constructed to quantify the risk of the outcomes and direct comparison meta-analysis model was constructed to compare the outcomes between BT injection and no BT injection or surgical pyloroplasty. Meta-regression was modeled to evaluate the effect of variations in different covariates among the individual studies on overall summary proportions. Nine studies enrolling 1070 patients were included. Pooled analyses showed that the risks of DGE and NEPI following intraoperative BT injection were 13.3% (95% confidence interval [CI]: 7.9-18.6%) and 15.2% (95% CI: 7.9-22.5%), respectively. There was no difference between BT injection and no BT injection in terms of DGE (odds ratio [OR]: 0.57, 95% CI: 0.20-1.61, P = 0.29) and NEPI (OR: 1.73, 95% CI: 0.42-7.12, P = 0.45). Moreover, BT injection was comparable to pyloroplasty in terms of DGE (OR: 0.85, 95% CI: 0.35-2.08, P = 0.73) and NEPI (OR: 8.20, 95% CI: 0.63-105.90, P = 0.11). Meta-regression suggested that male gender was negatively associated with the risk of DGE (coefficient: -0.007, P = 0.003). In conclusion, level 2 evidence suggests that intraoperative BT injection may not improve the risk of DGE and NEPI in patients undergoing esophagectomy. The risk of DGE seems to be higher in females and in early postoperative period. High quality randomized controlled trials with robust statistical power are required for definite conclusions. The results of the current study can be used for hypothesis synthesis and power analysis in future prospective trials.
