Meta-Analysis Review
BACKGROUND
Corpus callosotomy (CC) is appropriate for patients with seizures of a bilateral or diffuse origin, or those with seizures of a unilateral origin with rapid spread to the contralateral cerebral hemisphere. The efficiency of CC in patients with drug-resistant epilepsy is a long-term concern because most articles reporting the surgical results of CC arise from small case series, and the durations of follow-up vary.
METHODS
PubMed, Embase, Cochrane Library, and Web of Science were searched to identify papers published before November 8, 2021. The systematic review was completed following PRISMA guidelines. Outcomes were analyzed by meta-analysis of the proportions.
RESULTS
A total of 1644 patients with drug-resistant epilepsy (49 retrospective or prospective case series studies) underwent CC, and the follow-up time of all patients was at least 1 year. The rate of complete seizure freedom (SF) was 12.38% (95% confidence interval [CI], 8.17%-17.21%). Meanwhile, the rate of complete SF from drop attacks was 61.86% (95% CI, 51.87%-71.41%). The rates of complete SF after total corpus callosotomy (TCC) and anterior corpus callosotomy (ACC) were 11.41% (95% CI, 5.33%-18.91%) and 6.75% (95% CI, 2.76%-11.85%), respectively. Additionally, the rate of complete SF from drop attacks after TCC was significantly higher than that after ACC (71.52%, 95% CI, 54.22%-86.35% vs. 57.11%, 95% CI, 42.17%-71.49%). The quality of evidence for the three outcomes by GRADE assessment was low to moderate.
CONCLUSION
There was no significant difference in the rate of complete SF between TCC and ACC. TCC had a significantly higher rate of complete SF from drop attacks than did ACC. Furthermore, CC for the treatment of drug-resistant epilepsy remains an important problem for further investigation because there are no universally accepted standardized guidelines for the extent of CC and its benefit to patients. In future research, we will focus on this issue.

Review
[Purpose] Tilt table use is associated, most often, with the assessment of syncope. However, it also has applications for patients with neurologic and orthopedic problems. These applications do not appear to be widely applied. The purpose of this review, therefore, was to summarize the research literature addressing the use of tilt tables for treating specific musculoskeletal and neurologic impairments in adults. [Methods] Relevant literature was identified by searches of the PubMed, CINAHL, and Scopus databases and hand searches (December 2018 and October 2020). The methodological quality of the identified research articles was assessed using the PEDro scale. [Results] Of 482 unique articles identified, 20 matched the eligibility criteria of the review and were included. The studies varied widely in the populations studied, procedures used, and responses reported. The studies provide limited support for tilt table standing as an intervention. [Conclusion] However, evidence that some patients with neurologic conditions may respond positively to tilt-table standing is available. Among such individuals are those with decreased ankle range of motion, positive neurologic signs in the lower limbs, and decreased levels of consciousness.

Review
Efficacy and Safety of SPN-812 (Extended-Release Viloxazine) in Children and Adolescents with Attention-Deficit/Hyperactivity Disorder: A Systematic Review and Meta-Analysis.
BACKGROUND
SPN-812 has been approved for attention-deficit/hyperactivity disorder (ADHD) treatment in children and adolescents.
OBJECTIVE
We aimed to analyze the efficacy and safety of different doses of SPN-812 for ADHD pediatric patients of different ages, verify its clinical efficacy, and evaluate its safety.
METHODS
Up until 30 August 2023, randomized controlled trials (RCTs) were searched in EMBASE, MEDLINE, the Cochrane Library, and clinicaltrials.gov to evaluate different doses of SPN-812 and a placebo.
RESULTS
We pooled 1619 patients from five RCTs with a duration of 6-8 weeks. Patients (6-17 years old) in SPN-812 (100, 200, and 400 mg/d) groups were superior to the control group in all efficacy outcomes with lower attention-deficit/hyperactivity disorder rating scale-5 (ADHD-RS-5), Conners 3-parent short form composite T score (Conners 3-PS), Weiss functional impairment rating scale-parent (WFIRS-P), and increased clinical global impression-improvement (CGI-I) score (both < 0.05). At the same time, only SPN-812 300 mg/d did not show a significantly high risk of the adverse events (AEs) such as somnolence and decreased appetite ( = 0.09). There was no significant difference between placebo and SPN-812 groups (100, 200, and 400 mg/d) in serious adverse events (SAEs) such as syncope. The subgroup analyses showed that, both in children and adolescents subgroups, SPN-812 showed better efficacy than the placebo. The two age subgroups showed a significantly higher risk of AEs and an insignificant risk of SAEs than the placebo.
CONCLUSION
At present, SPN-812 (100, 200, and 400 mg/d) is superior to the corresponding control in efficacy measures. However, the safety problem cannot be ignored.

Review
There is a rising incidence of coronary artery diseases and myocardial infarction (MI). Mortality associated with acute MI (AMI) is directly linked to the time to receive treatment and missed diagnoses. Although health professionals are aware of typical AMI presentation, atypical MI is difficult to diagnose, which on the other hand, is likely to have an impact on morbidity and mortality. Therefore, it is prudent to know such atypical presentations, especially for emergency and primary care physicians. We aimed to systematically evaluate the clinical presentations of atypical MI and analyze them to characterize the common clinical presentations of atypical MI. We researched the PubMed database, did citation tracking, and performed Google Scholar advanced search to find the cases reported on the atypical presentation of MI published from January 2000 to September 2022. Articles of all languages were included; Google Translate was used to translate articles published in languages other than English. A total of 496 (56 PubMed articles, 340 citations from included PubMed articles, and 100 articles from Google Scholar advanced search) were screened; 52 case reports were evaluated, and their data were analyzed. Atypical presentations of myocardial infarction are vast; patients may have chest pain without typical characteristics of angina pain or may not have chest pain. No typical characterization could be done. Most patients were in their fifth decade or above of their life and commonly presented with pain and discomfort in the abdomen, head, and neck regions. Prodromal symptoms were consistent findings, and many patients had two to three comorbidities out of four common comorbidities, i.e., diabetes, hypertension, dyslipidemia, and substance abuse. A patient who is 50 years old or more, having comorbidities such as diabetes, hypertension, dyslipidemia, history of tobacco or marijuana usage, presenting with prodromal symptoms like shortness of breath, dizziness, fatigue, syncope, gastrointestinal discomfort or head/neck pain should be suspected for atypical MI.

Meta-Analysis Review
INTRODUCTION
We performed a systematic review and meta-analysis to identify predictors of serious clinical outcomes after an acute-care evaluation for syncope.
METHODS
We identified studies that assessed for predictors of short-term (≤30 days) serious clinical events after an emergency department (ED) visit for syncope. We performed a MEDLINE search (January 1, 1990 - July 1, 2017) and reviewed reference lists of retrieved articles. The primary outcome was the occurrence of a serious clinical event (composite of mortality, arrhythmia, ischemic or structural heart disease, major bleed, or neurovascular event) within 30 days. We estimated the sensitivity, specificity, and likelihood ratio of findings for the primary outcome. We created summary estimates of association on a variable-by-variable basis using a Bayesian random-effects model.
RESULTS
We reviewed 2,773 unique articles; 17 met inclusion criteria. The clinical findings most predictive of a short-term, serious event were the following: 1) An elevated blood urea nitrogen level (positive likelihood ratio [LR+]: 2.86, 95% confidence interval [CI] [1.15, 5.42]); 2); history of congestive heart failure (LR+: 2.65, 95%CI [1.69, 3.91]); 3) initial low blood pressure in the ED (LR+: 2.62, 95%CI [1.12, 4.9]); 4) history of arrhythmia (LR+: 2.32, 95%CI [1.31, 3.62]); and 5) an abnormal troponin value (LR+: 2.49, 95%CI [1.36, 4.1]). Younger age was associated with lower risk (LR-: 0.44, 95%CI [0.25, 0.68]). An abnormal electrocardiogram was mildly predictive of increased risk (LR+ 1.79, 95%CI [1.14, 2.63]).
CONCLUSION
We identified specific risk factors that may aid clinical judgment and that should be considered in the development of future risk-prediction tools for serious clinical events after an ED visit for syncope.

Meta-Analysis Review
INTRODUCTION
This systematic review aimed to give an overview of the current evidence surrounding the aetiology and management in terms of treatment and prevention of syncope in dental practices. Alongside the occurrence, the practitioner's competence, and the association between syncope and local anaesthetics were discussed.
METHODS
An electronic search in EMBASE, Web of Science, PubMed, Cochrane databases and a hand search were performed by 2 independent reviewers to identify studies up to November 2019. Eligibility criteria were applied and relevant data was extracted. Inclusion criteria covered all types of dental treatment under local anaesthesia or conscious sedation performed by a wide range of oral health care workers in their practices. Risk of bias of the included studies was assessed using the methodological tools recommend by Zeng et al. No restrictions were made to exclude papers from qualitive analysis based on risk of bias assessment.
RESULTS
The search yielded a total of 18 studies for qualitative analysis. With the exception of one prospective cohort study, all articles were considered having a high risk of bias. Meta-analysis showed that dentists encountered on average 1.2 cases of syncope per year. The male gender (RR = 2.69 [1.03, 7.02]), dental fear (RR = 3.55 [2.22, 5.70]), refusal of local anaesthesia in non-acute situations (OR = 12.9) and the use of premedication (RR = 4.70, [1.30, 16.90]) increased the risk for syncope. Treatment and prevention were underreported as both were solely discussed in one study. The supine recovery position with raised legs and oxygen administration (15l/min) was presented as an effective treatment. The Medical Risk-Related History (MRRH) system was proposed as prevention protocol, yet this protocol was ineffective in reducing incidence rates (p = 0.27). The majority of dentists (79.2%) were able to diagnose syncope, yet most (86%) lacked the skills for appropriate treatment. Only 57,6% of dental practices were equipped with an oxygen cylinder.
CONCLUSIONS
Syncope is the most common emergency in dental practices. Nonetheless, the vast majority of dentists do not seem competent nor prepared to manage this emergency. Psychogenic factors seem to play an important role in provoking syncope. Placing the patient in a supine reclined position with raised legs in combination with the administration of oxygen seems effective for regaining consciousness. Although valuable in many aspects, risk assessment by medical history taking is not proven to result in fewer episodes. The strength of these conclusions is low based on GRADE guidelines..

Review
Chronic myeloid leukemia (CML) represents a common condition in the spectrum of myeloproliferative disorders (MPD). It classically exhibits leukocytosis, but rarely presents with isolated thrombocytosis. This paper is designed to review the clinicopathologic features, treatment, and outcomes of patients with CML who present with isolated thrombocytosis. We searched PubMed, MEDLINE®, ScienceDirect, and Scopus for English-language articles about case series and case reports for the period 2000-2020 with the terms "chronic myeloid leukemia" and "thrombocytosis" and pooled them with a case from our institution. Cases were also incorporated from the reference list and screened for inclusion. A total of 20 cases were included in the final cohort. The male-to-female ratio was 1:1.86. The mean age of the patients at the time of initial diagnosis was 40.5 years (range: 9-77 years). Out of 17 cases with available data, seven (41%) were asymptomatic and found to have thrombocytosis incidentally upon routine blood work. Five cases (29.4%) either had a history of thrombotic events or presented with severe thrombotic complications, including ischemic cerebrovascular accidents (CVA), myocardial infarction (MI), pulmonary embolism (PE), and/or miscarriages. Four cases (23.5%) had more than one symptom at presentation, including headache, syncope, and bruising. The average platelet count was 1,923 × 10/L (range: 584-8,688 × 10/L), and one case (5%) had anemia. The bone marrow (BM) examination showed normal cellularity and normal myeloid to erythroid (M/E) ratio in seven (50%) and 11 (84.6%) out of the 14 and 13 cases with reported data, respectively. Moreover, megakaryocytes in the BM were small in 10 cases (71.4%), pleomorphic in three cases (21.4%), and dysplastic in one case (7.1%). Accurate differentiation among MPD subtypes and the exclusion of CML is critical in reaching a proper diagnosis to decide on proper therapy and eventually modify outcomes. Prompt evaluation for the precise diagnosis of patients presenting with isolated marked thrombocytosis will help expedite their diagnosis and initiation of a specific tyrosine kinase inhibitor (TKI) therapy, thereby promptly inducing remission, preventing thrombotic complications, and avoiding adverse drug events, which would eventually improve outcomes.

Review
As a further step towards the modernization of acupuncture, the objective of this review was to figure out the frequency and severity of adverse complications and events in acupuncture treatment reported from 1980 to 2013 in China. All first-hand case reports of acupuncture-related complications and adverse events that could be identified in the scientific literature were reviewed and classified according to the type of complication and adverse event, circumstance of the event, and long-term patient outcome. The selected case reports were published between 1980 and 2013 in 3 databases. Relevant papers were collected and analyzed by 2 reviewers. Over the 33 years, 182 incidents were identified in 133 relevant papers. Internal organ, tissue, or nerve injury is the main complications of acupuncture especially for pneumothorax and central nervous system injury. Adverse effects also included syncope, infections, hemorrhage, allergy, burn, aphonia, hysteria, cough, thirst, fever, somnolence, and broken needles. Qualifying training of acupuncturists should be systemized and the clinical acupuncture operations should be standardized in order to effectively prevent the occurrence of acupuncture accidents, enhance the influence of acupuncture, and further popularize acupuncture to the rest of the world.

Review
BACKGROUND
Familial Mediterranean fever (FMF), a hereditary auto-inflammatory disease, mainly affects ethnic groups living in the Mediterranean region. Early studies reported colchicine may potentially prevent FMF attacks. For people who are colchicine-resistant or intolerant, drugs such as anakinra, rilonacept, canakinumab, etanercept, infliximab or adalimumab might be beneficial. This is an update of the review last published in 2018.
OBJECTIVES
To evaluate the efficacy and safety of interventions for reducing inflammation in people with FMF.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase and four Chinese databases on in August 2021. We searched clinical trials registries and references listed in relevant reports. The last search was 17 August 2021.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) of people with FMF, comparing active interventions (including colchicine, anakinra, rilonacept, canakinumab, etanercept, infliximab, adalimumab, thalidomide, tocilizumab, interferon-α and ImmunoGuard (herbal dietary supplement)) with placebo or no treatment, or comparing active drugs to each other.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodology. We assessed certainty of the evidence using GRADE.
MAIN RESULTS
We included 10 RCTs with 312 participants (aged three to 53 years), including five parallel and five cross-over designed studies. Six studies used oral colchicine, one used oral ImmunoGuard, and the remaining three used rilonacept, anakinra or canakinumab as a subcutaneous injection. The duration of each study arm ranged from one to eight months. There were inadequacies in the design of the four older colchicine studies and the two studies comparing a single to a divided dose of colchicine. However, the four studies of ImmunoGuard, rilonacept, anakinra and canakinumab were generally well-designed. We aimed to report on the number of participants experiencing an attack, the timing of attacks, the prevention of amyloid A amyloidosis, adverse drug reactions and the response of a number of biochemical markers from the acute phase of an attack; but no study reported on the prevention of amyloid A amyloidosis. Colchicine (oral) versus placebo After three months, colchicine 0.6 mg three times daily may reduce the number of people experiencing attacks (risk ratio (RR) 0.21, 95% confidence interval (CI) 0.05 to 0.95; 1 study, 10 participants; low-certainty evidence). One study (20 participants) of colchicine 0.5 mg twice daily showed there may be no difference in the number of participants experiencing attacks at two months (RR 0.78, 95% CI 0.49 to 1.23; low-certainty evidence). There may be no differences in the duration of attacks (narrative summary; very low-certainty evidence), or in the number of days between attacks: (narrative summary; very low-certainty evidence). Regarding adverse drug reactions, one study reported loose stools and frequent bowel movements and a second reported diarrhea (narrative summary; both very low-certainty evidence). There were no data on acute-phase response. Rilonacept versus placebo There is probably no difference in the number of people experiencing attacks at three months (RR 0.87, 95% CI 0.59 to 1.26; moderate-certainty evidence). There may be no differences in the duration of attacks (narrative summary; low-certainty evidence) or in the number of days between attacks (narrative summary; low-certainty evidence). Regarding adverse drug reactions, the rilonacept study reported there may be no differences in gastrointestinal symptoms, hypertension, headache, respiratory tract infections, injection site reactions and herpes, compared to placebo (narrative summary; low-certainty evidence). The study narratively reported there may be no differences in acute-phase response indicators after three months (low-certainty evidence). ImmunoGuard versus placebo The ImmunoGuard study observed there are probably no differences in adverse effects (moderate-certainty evidence) or in acute-phase response indicators after one month of treatment (moderate-certainty evidence). No data were reported for the number of people experiencing an attack, duration of attacks or days between attacks. Anakinra versus placebo A study of anakinra given to 25 colchicine-resistant participants found there is probably no difference in the number of participants experiencing an attack at four months (RR 0.76, 95% CI 0.54 to 1.07; moderate-certainty evidence). There were no data for duration of attacks or days between attacks. There are probably no differences between anakinra and placebo with regards to injection site reaction, headache, presyncope, dyspnea and itching (narrative summary; moderate-certainty evidence). For acute-phase response, anakinra probably reduced C-reactive protein (CRP) after four months (narrative summary; moderate-certainty evidence). Canakinumab versus placebo Canakinumab probably reduces the number of participants experiencing an attack at 16 weeks (RR 0.41, 95% CI 0.26 to 0.65; 1 study, 63 colchicine-resistant participants; moderate-certainty evidence). There were no data for the duration of attacks or days between attacks. The included study reported the number of serious adverse events per 100 patient-years was probably 42.7 with canakinumab versus 97.4 with placebo among people with colchicine-resistant FMF (moderate-certainty evidence). For acute-phase response, canakinumab probably caused a higher proportion of participants to have a CRP level of 10 mg/L or less compared to placebo (68% with canakinumab versus 6% with placebo; 1 study, 63 participants; moderate-certainty evidence). Colchicine single dose versus divided dose There is probably no difference in the duration of attacks at three months (MD -0.04 hours, 95% CI -10.91 to 10.83) or six months (MD 2.80 hours, 95% CI -5.39 to 10.99; moderate-certainty evidence). There were no data for the number of participants experiencing an attack or days between attacks. There is probably no difference in adverse events (including anorexia, nausea, diarrhea, abdominal pain, vomiting and elevated liver enzymes) between groups (narrative summary; moderate-certainty evidence). For acute-phase response, there may be no evidence of a difference between groups (narrative summary; low- to moderate-certainty evidence).
AUTHORS' CONCLUSIONS
There were limited RCTs assessing interventions for people with FMF. Based on the evidence, three times daily colchicine may reduce the number of people experiencing attacks, colchicine single dose and divided dose may not be different for children with FMF, canakinumab probably reduces the number of people experiencing attacks, and anakinra or canakinumab probably reduce CRP in colchicine-resistant participants; however, only a few RCTs contributed data for analysis. Further RCTs examining active interventions, not only colchicine, are necessary before a comprehensive conclusion regarding the efficacy and safety of interventions for reducing inflammation in FMF can be drawn.

OBJECTIVE
To describe the natural history of afferent baroreflex failure (ABF) based on systematic review of clinical and laboratory data in patients with a diagnosis of ABF at Mayo Clinic Rochester.
METHODS
We performed a retrospective chart review of all patients who underwent standardized autonomic reflex testing between 2000 and 2020 and had confirmation of the diagnosis of ABF by an autonomic disorders specialist. Patients were identified using a data repository of medical records. Variables included demographic, all-cause mortality, medications, ABF manifestations, comorbidities, and laboratory (autonomic testing, blood pressure monitoring, echocardiogram, brain imaging, plasma catecholamines, serum sodium level, and kidney function tests).
RESULTS
A total of 104 patients with ABF were identified. Head and neck radiation was the most common etiology (86.5%), followed by neck surgery (5.8%) and other causes (7.7%). The most common findings were hypertension (87.5%), fluctuating blood pressure (78.8%), orthostatic hypotension (91.3%), syncope (58.6%), headache (22.1%), and tachycardia (20.2%). Patients commonly received antihypertensives (66.3%), pressor agents (41.3%), or a combination of both (19.2%). The median latency from completion of radiation to ABF was longer compared to the latency in the surgery group ( < 0.0001). Comorbidities, including complications from neck radiation, were frequently seen and all-cause mortality was 39.4% over a 20-year period.
CONCLUSIONS
ABF should be suspected in patients with prior head and neck cancer treated by radiation or surgery who present with labile hypertension and orthostatic hypotension. Management may require both antihypertensive and pressor medications. The morbidity and mortality in ABF are high.
