Meta-Analysis Review
INTRODUCTION
Intraoperative neuromonitoring (IONM) has been a commonly used technology during thyroid surgery aimed at reducing the incidence of recurrent laryngeal nerve palsy (RLNP), which is a severe complication and leads to significant impacts on a patient's life. In order to give a comprehensive assessment for potential benefits and disadvantage of IONM, this meta-analysis and systematic review discusses RLNP rate, predictive power, continuous intraoperative neuromonitoring (CIONM), and emphasises application during thyroid cancer surgeries.
METHODS
A literature search was performed in the following electronic databases: PubMed, Embase, and the Cochrane library from January 1, 2004 to July 30, 2016. After applying inclusion and exclusion criteria, 24 studies, including four prospective randomised trials, were selected. Heterogeneity of studies was checked by the Cochran Q test. Publication bias was assessed by funnel plots with Egger's linear regression test of asymmetry. Odds ratio (OR) was calculated by random effects model.
RESULTS
Overall, 9203 patients and 17,203 nerves at risk (NAR) were included. Incidence of overall, transient, and persistent RLNP in IONM group were, respectively, 3.15%, 1.82%, and 0.67%, whereas for the ID group, they were 4.37%, 2.58%, and 1.07%. The summary OR of overall, transient, and persistent RLNP compared using IONM and ID were, respectively, 0.81 (95%CI 0.66-0.99), 0.76 (95%CI 0.61-0.94), and 0.78 (95%CI 0.55-1.09).
CONCLUSIONS
The presented data showed benefits of reducing RLNP rate by using IONM, but without statistical significance for persistent RLNP rate. For patients with thyroid cancer who undergo total thyroidectomy, using IONM may improve the outcome by reducing amount of residual thyroid tissue. However, no benefits were found for thyroid reoperation; visual identification and careful dissection remain standard for this challenging procedure. In addition, the relative low positive predictive power indicated intermittent intraoperative neuromonitoring (IIONM) may not be reliable; but CIONM was showed to be a more promising method, with prudent approach.

Meta-Analysis Review
Hypoglossal-facial nerve (12-7) anastomosis can restore symmetry and voluntary movement on the face in patients with facial nerve paralysis. Traditional 12-7 transfer includes direct end-to-end nerve anastomosis, sacrificing the entire hypoglossal nerve. Contemporary, end-to-side anastomosis, or split anastomosis techniques limit tongue morbidity by preserving some hypoglossal nerve. Direct outcome comparisons between these techniques are limited. To compare reported outcomes of facial movement, tongue, speech, and swallow outcomes among the different types of hypoglossal-facial nerve anastomosis schemes. For this systematic review and meta-analysis, a comprehensive strategy was designed to search PubMed, Scopus, and the Cochrane Database from inception to January 2021, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, reporting guideline yielding 383 results. Any participant who underwent 12-7 transfer using any of the three techniques, with or without an interposition graft, and had documented preoperative and postoperative evaluation of facial nerve function with a validated instrument such as House-Brackmann (HB), was considered for inclusion. Secondary outcomes of synkinesis, tongue atrophy, and speech or swallowing dysfunction were also compared. Forty-nine studies met inclusion criteria, representing data from 961 total patients who underwent 12-7 transfer. The proportion of good HB outcomes (HB I-III) did not differ by anastomosis type: End-to-side and end-to-end anastomosis (73% vs. 59%, = 0.07), split and end-to-end anastomosis (62% vs. 59%, = 0.88), and end-to-side anastomosis and split anastomosis (73% vs. 62%, = 0.46). There was no difference in reported synkinesis rates between the anastomosis types. However, end-to-side anastomosis ( = 6.55, < 0.01) and split anastomosis ( = 3.58, < 0.01) developed less tongue atrophy than end-to-end anastomosis. End-to-side anastomosis had less speech/swallowing dysfunction than end-to-end anastomosis ( = 3.21, < 0.01). End-to-side and split anastomoses result in similar HB facial nerve outcomes as the traditional end-to-end 12-7 anastomosis. End-to-side anastomosis has decreased complications of tongue atrophy and speech/swallow dysfunction compared to end-to-end anastomosis. In addition, split anastomosis has decreased rates of tongue atrophy compared to end-to-end anastomosis.

Review
INTRODUCTION
The gracilis muscle free flap has gained popularity in head and neck reconstruction due to minimal donor-site morbidity, reliable vascular pedicle, strong muscular component, and possibility to perform nerve coaptation. However, almost all the existing evidence in the literature is related to its use for facial palsy reanimation. The aim of this study was therefore to review and provide a comprehensive summary of all the possible indications and outcomes of this versatile free flap in head neck reconstructive surgery.
MATERIALS AND METHODS
A systematic review of the literature was conducted including articles from 1970 to 2019. All articles were examined and described.
RESULTS
Twenty-seven papers published between 1994 and 2019 were identified for analysis. The evidence highlights the use of the gracilis muscle free flap for parotid, forehead and midface defects, oral tongue, oral sphincter, lower and upper lip, cheek, and oral commissure defects, among others, as the most common defects reconstructed.
CONCLUSION
This flap represents an easy to harvest and versatile free flap with low donor-site morbidity and multiple proven uses in head & neck reconstruction. We therefore encourage reconstructive surgeons to include this flap in their armoury, either as a first or as a second-line option.

Review
OBJECTIVE
To systematically review the published cases of bilateral facial palsy (BFP) to gather evidence on the clinical assessment and management of this pathology.
METHODS
Following PRISMA statement recommendations, 338 abstracts were screened independently by two authors. Inclusion criteria were research articles of human patients affected by BFP, either central or peripheral; English, Italian, French or Spanish language; availability of the abstract, while exclusion criteria were topics unrelated to FP, and mention of unilateral or congenital FP. Only full-text articles reporting the diagnostic work-up, the management, and the prognosis of the BFP considered for further specific data analysis.
RESULTS
A total of 143 articles were included, resulting a total of 326 patients with a mean age of 36 years. The most common type of the paralysis was peripheral (91.7%), and the autoimmune disease was the most frequent aetiology (31.3%). The mean time of onset after first symptoms was 12 days and most patients presented with a grade higher than III. Associated symptoms in idiopathic BFP were mostly non-specific. The most frequently positive laboratory exams were cerebrospinal fluid analysis, autoimmune screening and peripheral blood smear, and the most performed imaging was MRI. Most patients (74%) underwent exclusive medical treatment, while a minority were selected for a surgical or combined approach. Finally, in more than half of cases a complete bilateral recovery (60.3%) was achieved.
CONCLUSIONS
BFP is a disabling condition. If a correct diagnosis is formulated, possibilities to recover are elevated and directly correlated to the administration of an adequate treatment.

Review
Type 1 diabetes and type 2 diabetes have high rates of associated exocrine pancreatic insufficiency (EPI). This review evaluated the current evidence on prevalence and treatment of EPI in type 1 and type 2 diabetes and compared general population prevalence rates of EPI and prevalence of other common gastrointestinal conditions such as celiac disease and gastroparesis based on within-diabetes rates of common gastrointestinal (GI) conditions. Prevalence of EPI in type 1 diabetes ranges from 14% to 77.5% (median 33%), while EPI in type 2 diabetes ranges from 16.8% to 49.2% (median 29%), and where type of diabetes is not specified in studies, ranges from 5.4% to 77%. In studies with control groups of the general population, prevalence of EPI overall in those without diabetes ranged from 4.4% to 18%, median 13%, which is comparable with other estimated general population prevalence rates of EPI (10%-20%). Cumulatively, this suggests there may be significant numbers of people with diabetes with EPI who are undiagnosed. People with diabetes (both type 1 and type 2) who present with gastrointestinal symptoms, such as steatorrhea or changes in stool, bloating, and/or abdominal pain, should be screened for EPI. Both diabetes specialists and gastroenterologists and primary care providers should be aware of the high rates of prevalence of diabetes and EPI and recommend fecal elastase-1 screening for people with diabetes and GI symptoms.

Review
INTRODUCTION
Dyke-Davidoff-Masson syndrome (DDMS), or cerebral hemiatrophy, was first described in 1933. It is characterised by cerebral injury that causes hypoplasia in one of the cerebral hemispheres. The disease has different clinical degrees and two aetiologies: congenital and acquired. Radiological findings depend on the degree of injury and the patient's age at the time.
OBJECTIVE
To provide information on the main clinical and radiological characteristics of this disease.
METHODS
A systematic review of the PubMed, MEDLINE, and LILACS databases was conducted using only one keyword. Dyke-Davidoff-Masson syndrome. A total of 223 studies were identified, and the results are presented in tables and graphics.
RESULTS
The mean age of the patients was 19.44 (0-83 years), and the majority were male (55.32%). The most common types of epileptic seizures were generalised tonic-clonic seizures (31 cases), focal impaired awareness seizures (20 cases), focal motor seizures (13 cases), focal to bilateral tonic-clonic seizures (nine cases), and focal myoclonic seizures (one case). The main features of the disease were rapid deep tendon reflexes and extensor cutaneous-plantar tendon reflexes (30 cases - 16%), contralateral hemiparesis or hemiplegia (132 cases - 70%), gait alterations (16 cases - 9%), facial paralysis (nine cases - 5%), facial asymmetry (58 cases - 31%), limb asymmetry (20 cases - 11%), delayed developmental milestones (39 cases - 21%), intellectual disability (87 cases - 46%), and language/speech disorders (29 cases - 15%). Left hemisphere atrophy was the most prevalent.
CONCLUSION
DDMS is a rare syndrome, and several questions regarding this disease remain unanswered. This systematic review aims to elucidate the most common clinical and radiological aspects of the disease and emphasises the need for further investigation.

Review
Evaluation of the therapeutic efficacy and tolerability of current drug treatments on the clinical outcomes of paediatric spinal muscular atrophy type 1: A systematic review.
Spinal muscular atrophy (SMA) is a severe hereditary lower motor neuron disorder characterised by degeneration of alpha motor neurons in the spinal cord, resulting in progressive weakness and paralysis of proximal muscles. A systematic literature search was carried out by using PRISMA guidelines and searching through different databases that could provide findings of evidence on the health outcomes of the approved therapies for the management of paediatric SMA type 1 regarding efficacy with follow-up in terms of motor and respiratory functions and the tolerability and incidence of adverse drug reactions (ADRs) post-treatment from real-world publications. Half of the publications (50%) had a prospective observational design. Eight studies (66.7%) assessed nusinersen, and three studies (25%) assessed onasemnogene abeparvovec with a duration of follow-up ranging from 6 months to 3 years to evaluate the motor and respiratory functions using different assessment tools, hospitalisation rates, and the tolerability and incidence of ADRs post-treatment. The three currently approved treatments for SMA type 1 provided good support and health outcomes in terms of motor function, respiratory outcomes, reduction of hospitalisations, and improvement of survival. Nevertheless, uncertainties regarding continued improvement after long-term illness and the generalizability of results are still unknown.

Review
BACKGROUND
Despite the potentially good efficacy of acupuncture therapy in the management of post-stroke spastic paralysis demonstrated in previous studies, further verification through meta-analysis can be conducive to eliminating the inconclusive of treatment outcomes in prior findings. This systematic review and meta-analysis were thus performed to comprehensively investigate the effects of acupuncture on the daily living abilities, upper and lower limb motor function, and related functional indices of post-stroke patients with spastic paralysis.
METHODS
We conducted a computer search to collect data from PubMed, PEDro, Clinical SportDiscus, and Scopus. The inclusion criteria followed the Population-Intervention-Comparison-Outcome (PICO) principle. Literature screening, data extraction, and quality assessment of the research articles were performed by two independent investigators. Standard mean difference and 95% confidence intervals of the data were analyzed using either a random-effects model or a fixed-effects model.
RESULTS
Acupuncture therapy appeared to be effective in mitigating the limb pain of post-stroke patients with spastic paralysis (RR = -0.04, 95% CI: -0.26, 0.17), ameliorating their daily life ability (RR = 4.66, 95% CI: -0.74, 10.05), and improving their hand function (RR = 0.65, 95% CI: 0.40, 0.90) and lower limb function (RR = 0.35, 95% CI: 0.09, 0.62).
CONCLUSION
Acupuncture therapy provides more pronounced improvement in the daily life ability and limb motor function of post-stroke patients with spastic paralysis than conventional treatment regimens. Thus, acupuncture therapy can be a viable treatment option for the management of spastic paralysis following stroke.

Review
Sleep paralysis (SP) is a mixed state of consciousness and sleep, combining features of rapid eye movement (REM) sleep with those of wakefulness. The exact cause of SP is unknown, and its prevalence varies among the studies. We aim to identify SP's global prevalence, the affected population's characteristics, and the SP's clinical picture. We searched three databases (PubMed, Scopus, and Web of Science (WoS)) using a unique search strategy to identify eligible studies. All observational studies identifying the prevalence or frequency of sleeping paralysis were included. No exclusions are made based on country, race, or questionnaire. The analysis was performed using the latest version of R software (R Core Team, Vienna, Austria). The analysis included 76 studies from 25 countries with 167,133 participants. The global prevalence of SP was 30% (95% CI (22%, 39%)). There were similar frequencies of isolated SP and SP (33%, 95% CI (26%, 42%), I2 = 97%, P <0.01; 31%, 95% CI (21%, 43%), I2 = 100%, P = 0, respectively). A subgroup analysis showed that the majority of those who experienced SP were psychiatric patients (35%, 95% CI (20%, 55%), I2 = 96%, P <0.01). The prevalence among non-psychiatric patients was among students (34%, 95% CI (23%, 47%), I2 = 100%, P = 0). Auditory and visual hallucinations were reported in 24.25% of patients. Around 4% had only visual hallucinations. Meta-regression showed no association between the frequency of SP and sex. Publication bias was detected among the included studies through visual inspection of funnel plot asymmetry. Our findings revealed that 30% of the population suffered from SP, especially psychiatric patients and students. The majority of SP cases lacked associated hallucinations, while a noteworthy proportion experienced combined visual and auditory hallucinations.

Meta-Analysis Review
OBJECTIVES
To evaluate the difference of tau burden between patients with progressive supranuclear palsy (PSP) and healthy controls (HCs) or other neurodegenerative diseases using tau-positron emission tomography (PET) imaging.
METHODS
A systematic search on PubMed, Embase, and Web of Science databases was performed for tau-PET studies in PSP patients, up to April 1, 2022. Standardized mean differences (SMDs) of tau tracer uptake were calculated using random-effects models. Subgroup analysis based on the type of tau tracers, meta-regression, and sensitivity analysis were conducted.
RESULTS
Twenty-seven studies comprising 553 PSP, 626 HCs, and 406 other neurodegenerative diseases were included. Compared with HCs, PSP patients showed elevated tau binding in basal ganglia, midbrain, dentate nucleus, cerebellar white matter, and frontal lobe with decreasing SMD (SMD: 0.390-1.698). Compared with Parkinson's disease patients, increased tau binding was identified in the midbrain, basal ganglia, dentate nucleus, and frontal and parietal lobe in PSP patients with decreasing SMD (SMD: 0.503-1.853). PSP patients showed higher tau binding in the subthalamic nucleus (SMD = 1.351) and globus pallidus (SMD = 1.000), and lower binding in the cortex and parahippocampal gyrus than Alzheimer's disease patients (SMD: - 2.976 to - 1.018). PSP patients showed higher midbrain tau binding than multiple system atrophy patients (SMD = 1.269).
CONCLUSION
Tau PET imaging indicates different topography of tau deposition between PSP patients and HCs or other neurodegenerative disorders. The affinity and selectivity of tracers for 4R-tau and the off-target binding of tracers should be considered when interpreting the results.
