Review
PURPOSE
Primary hyperhidrosis is a pathological disorder of unknown etiology, affecting 0.6-5% of the population, and causing severe functional and social handicaps. As the etiology is unknown, it is not possible to treat the root cause. Recently some differences between affected and non-affected people have been reported. The aim of this review is to summarize these new etiological data.
METHODS
Search of the literature was performed in the PubMed/Medline Database and pertinent articles were retrieved and reviewed. Additional publications were obtained from the references of these articles.
RESULTS
Some anatomical and pathophysiological characteristics (as well as enzymatic, metabolic, and neurological dysfunctions) have been observed in hyperhidrotic subjects; three main possible etiological factors predominate. A familial trait seems to exist, and genetic loci associated with hyperhidrosis have been identified. Histological differences were observed in sympathetic ganglia of hyperhidrotic subjects: the ganglia were larger and contained a higher number of ganglion cells. A higher expression of acetylcholine and alpha-7 neuronal nicotinic receptor subunit in the sympathetic ganglia of patients with hyperhidrosis has been reported.
CONCLUSIONS
Despite these accumulated data, the etiology of primary hyperhidrosis remains obscure. Nevertheless, three main lines for future research seem to be delineated: genetics, histological observations, and enzymatic studies.

Review
BACKGROUND
Sphenopalatine ganglion is the largest collection of neurons in the calvarium outside of the brain. Over the past century, it has been a target for interventional treatment of head and facial pain due to its ease of access. Block, radiofrequency ablation, and neurostimulation have all been applied to treat a myriad of painful syndromes. Despite the routine use of these interventions, the literature supporting their use has not been systematically summarized. This systematic review aims to collect and summarize the level of evidence supporting the use of sphenopalatine ganglion block, radiofrequency ablation and neurostimulation.
METHODS
Medline, Google Scholar, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases were reviewed for studies on sphenopalatine ganglion block, radiofrequency ablation and neurostimulation. Studies included in this review were compiled and analyzed for their treated medical conditions, study design, outcomes and procedural details. Studies were graded using Oxford Center for Evidence-Based Medicine for level of evidence. Based on the level of evidence, grades of recommendations are provided for each intervention and its associated medical conditions.
RESULTS
Eighty-three publications were included in this review, of which 60 were studies on sphenopalatine ganglion block, 15 were on radiofrequency ablation, and 8 were on neurostimulation. Of all the studies, 23 have evidence level above case series. Of the 23 studies, 19 were on sphenopalatine ganglion block, 1 study on radiofrequency ablation, and 3 studies on neurostimulation. The rest of the available literature was case reports and case series. The strongest evidence lies in using sphenopalatine ganglion block, radiofrequency ablation and neurostimulation for cluster headache. Sphenopalatine ganglion block also has evidence in treating trigeminal neuralgia, migraines, reducing the needs of analgesics after endoscopic sinus surgery and reducing pain associated with nasal packing removal after nasal operations.
CONCLUSIONS
Overall, sphenopalatine ganglion is a promising target for treating cluster headache using blocks, radiofrequency ablation and neurostimulation. Sphenopalatine ganglion block also has some evidence supporting its use in a few other conditions. However, most of the controlled studies were small and without replications. Further controlled studies are warranted to replicate and expand on these previous findings.

PURPOSE
The impact of patellar denervation with electrocautery in total knee arthroplasty (TKA) on post-operative outcomes has been under debate. This study aims to conduct a meta-analysis and systematic review to compare the benefits and risks of circumpatellar electrocautery with those of non-electrocautery in primary TKAs.
METHODS
Comparative and randomized clinical studies were identified by conducting an electronic search of articles dated up to September 2012 in PubMed, EMBASE, Scopus, and the Cochrane databases. Six studies that focus on a total of 849 knees were analysed. A random-effects model was conducted using the inverse-variance method for continuous variables and the Mantel-Haenszel method for dichotomous variables.
RESULTS
There was no significant difference in the incidence of anterior knee pain between the electrocautery and non-electrocautery groups. In term of patellar score and Knee Society Score, circumpatellar electrocautery improved clinical outcomes compared with non-electrocautery in TKAs. The statistical differences were in favour of the electrocautery group but have minimal clinical significance. In addition, the overall complications indicate no statistical significance between the two groups.
CONCLUSIONS
This study shows no strong evidence either for or against electrocautery compared with non-electrocautery in TKAs.

Meta-Analysis
PURPOSE
To perform a systematic review and meta-analysis of published studies to evaluate the analgesic efficacy and safety of computed tomography (CT)-guided single celiac plexus neurolysis (CPN) with the injection of a neurolytic agent into the celiac plexus in one session (CT-guided single CPN).
METHODS
PubMed, the Cochrane Library, and Ichushi-Web were searched for English or Japanese articles published up to February 2022, which reported findings about patients who underwent CT-guided single CPN. The outcome measures assessed in the systematic review and meta-analysis were the pain measurement scales from 0 to 10 before and after the intervention and the rate of minor and major complications.
RESULTS
The pooled pain measurement scales at pre-intervention and 1- or 2-, 7-, 30-, 60-, 90-, and 180-day post-intervention was 6.72 (95% confidence interval [CI], 4.77-9.46, I = 98%), 2.31 (95% CI 2.31-4.44, I = 92%), 2.84 (95% CI 1.39-5.79, I = 95%), 3.36 (95% CI 1.66-6.77, I = 98%), 3.19 (95% CI 1.44-7.08, I = 59%), 3.87 (95% CI 1.88-7.97, I = 0%), and 3.40 (95% CI 3.02-3.83, I = not applicable), respectively. The pooled minor complication rates of diarrhea, hypotension, nausea or vomiting, and pain associated with the procedure were 18% (95% CI 8-37%, I = 45%), 16% (95% CI 2-58%, I = 76%), 6% (95% CI 2-16%, I = 1%), and 7% (95% CI 2-21%, I = 17%), respectively. There was no major complication in the included studies.
CONCLUSION
CT-guided single CPN can be performed safely and provides immediate analgesic efficacy although the amount of heterogeneity is characterized as large. Further investigation of its long-term analgesic efficacy is required.

Meta-Analysis Review
INTRODUCTION
Celiac plexus neurolysis (CPN) has been developed as adjunctive therapy to medical management (MM) of abdominal pain associated with unresectable pancreatic cancer. We aimed to conduct a systematic review and meta-analysis to obtain updated and more accurate evidence on the efficacy of additional types of CPN, including endoscopic ultrasound-guided CPN (EUS-CPN).
METHODS
On March 16, 2021, we performed searches of PubMed, Web of Science, and CENTRAL for original randomized controlled trials (RCTs). We defined the primary outcome as a standardized pain intensity score with a range of 0-10, and evaluated the mean difference between the CPN + MM and MM groups at 4, 8, and 12 weeks after the initiation of treatment. We used a random-effects model to synthesize the mean differences across RCTs.
RESULTS
We selected 10 RCTs involving 646 individuals. The synthesized mean difference in the pain intensity score between the CPN + MM and MM groups was -0.58 (95% confidence interval [CI]: -1.09 to -0.07) (p = 0.034) in favor of CPN + MM at 4 weeks, -0.46 (95%CI: -1.00 to 0.08) (p = 0.081) at 8 weeks, and - 1.35 (95%CI: -3.61 to 0.92) (p = 0.17) at 12 weeks.
CONCLUSIONS
This updated meta-analysis of CPN demonstrates its efficacy for managing abdominal pain at 4 weeks. Although there are various limitations, when abdominal pain in patients with unresectable pancreatic cancer is poorly controlled with MM alone, CPN should be an option even if the duration of effect is short-lived, taking into account the absence of serious adverse events.

Meta-Analysis Review
BACKGROUND
Previous studies have reached mixed results regarding the effects of patellar denervation with electrocautery (PD) on total knee replacement (TKR). This systematic review and meta-analysis aimed to summarize all available literatures to investigate the influence of PD on postoperative anterior knee pain (AKP) and knee function after TKR.
METHODS
Electronic databases, including PubMed, Cochrane Library and Embase, were searched from their inception to March 2021. Randomized controlled trials (RCT) and quasi-randomized controlled trials (quasi-RCT) comparing PD and non-patellar denervation (NPD) in TKR were selected, and the Cochrane risk of bias tool was used to assess the quality of included trials. AKP prevalence was defined as the primary outcome.
RESULTS
A total of 12 RCTs and one quasi-RCT enrolled 1895 knees proved eligible. PD knees had significantly lower AKP prevalence than NPD knees (odds ratio [OR] = 0.54; 95% confidence intervals [95% CI], 0.36-0.81; p = 0.003). There was no difference between PD and NPD in terms of visual analogue scale for knee pain and range of motion, American knee society knee score, American knee society function score, patellar feller score, Oxford knee score for knee function. The results of subgroup analysis based on follow-up duration and patella resurfacing were in accordance with the results. PD knees were not associated with a higher risk of complication or revision.
CONCLUSION
PD can significantly reduce the AKP prevalence following TKR without increasing the risk of complication and revision. Although the pain relief effect of PD may not be associated with improved knee function after TKR, this procedure is preferred in both patella resurfacing and patella non-resurfacing TKR.

Meta-Analysis Review
The increased popularity of paravertebral block (PVB) can be attributed to its relative safety and comparable efficacy when compared with epidural analgesia. It has thus been recommended for open cholecystectomy and other less painful surgeries such as inguinal herniorraphy and appendectomy. We performed a systematic review of PVB in paediatric abdominal conditions to assess its clinical efficacy and side effects compared with other analgesic therapies.A search of Medline, Embase, and Web of Science and hand-searching references from inception date to May 2016 was done. Relevant studies were randomized clinical trials in patients 0-18 years old comparing PVB (single shot or continuous catheter) with any comparator and analgesic medication. Pain scores, rescue analgesia and adverse events were compared.The systematic reviews identified six trials enrolling 358 paediatric patients. PVB medications included bupivacaine, ropivacaine, lidocaine, and fentanyl. Surgical procedures included inguinal herniorraphy, cholecystectomy, and appendectomy. The standardized mean difference in early pain scores favoured PVB: 0.85 [95% confidence interval (CI) 0.12-1.58] at 4-6 h and 0.64 (95% CI 0.28-1.00) at 24 h. One study reported a reduced length of stay. Parental [odds ratio (OR) 5.12 (95% CI 2.59-10.1)] and surgeon [OR 6.05 (95% CI 2.25-16.3)] satisfaction were higher in those receiving a PVB. No major complications occurred with a PVB.PVB resulted in minimally improved pain scores for up to 24 h after surgery, reduced rescue analgesia requirements, and increased surgeon and parental satisfaction. PVB is a good alternative to caudal and ilioinguinal block in paediatric abdominal surgery.

Review
Perineural catheter infection is a rare but potentially dramatic complication of continuous peripheral nerve block. Different risk factors have been identified and the incidence of infection is increased in trauma victims, intensive care unit patients, immunodeficient individuals, and diabetic patients. Also, postoperative hyperglycemia, the absence of antibiotic prophylaxis, and catheter lasting more than 48 hours seem to be associated with a greater risk of infection. Skin disinfection and a strict aseptic technique during catheter placement are fundamental. The use of micropore filters, antiseptic dressings, catheter tunneling, and aseptic preparation of the infused drug has all been hypothesized to reduce infection rate, but the existing evidence is conflicting. Infection is a rare complication of continuous peripheral nerve blocks. Severe and even fatal cases have been reported, even if morbidity is generally very low. The identification of high risk patients and adoption of preventive measures might reduce the incidence of this complication.

Review
AIM
To conduct a systematic review and evaluate the quality of evidence for interventions to prevent hip displacement in children with cerebral palsy (CP).
METHOD
A systematic review was performed using American Academy of Cerebral Palsy and Developmental Medicine (AACPDM) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Searches were completed in seven electronic databases. Studies were included if participants had CP and the effectiveness of the intervention was reported using a radiological measure. Results of orthopaedic surgical interventions were excluded.
RESULTS
Twenty-four studies fulfilled the inclusion criteria (4 botulinum neurotoxin A; 2 botulinum neurotoxin A and bracing; 1 complementary and alternative medicine; 1 intrathecal baclofen; 1 obturator nerve block; 8 positioning; 7 selective dorsal rhizotomy). There was significant variability in treatment dosages, participant characteristics, and duration of follow-up among the studies. Overall, the level of evidence was low. No intervention in this review demonstrated a large treatment effect on hip displacement.
INTERPRETATION
The level and quality of evidence for all interventions aimed at slowing or preventing hip displacement is low. There is currently insufficient evidence to support or refute the use of the identified interventions to prevent hip displacement or dislocation in children and young people with CP.
WHAT THIS PAPER ADDS
High-quality evidence on prevention of hip displacement is lacking. No recommendations can be made for preventing hip displacement in children with cerebral palsy because of poor-quality evidence. High-quality, prospective, longitudinal studies investigating the impact of interventions on hip displacement are required.

Meta-Analysis Review
PURPOSE OF REVIEW
To evaluate the effectiveness of radiofrequency neurotomy in managing sacroiliac joint pain utilizing a systematic review with meta-analysis of randomized controlled trials (RCTs) and observational studies.
RECENT FINDINGS
The prevalence of sacroiliac joint pain is estimated at around 25% of low back pain cases, and its diagnosis lacks a gold standard. Treatments include exercise therapy, injections, ablation, and fusion, with variable effectiveness. COVID-19 altered utilization patterns of interventions, including sacroiliac joint procedures, and the evidence for these interventions remains inconclusive. Recently, Medicare has issued its local coverage determinations (LCDs) in the United States, which provides noncoverage of sacroiliac joint radiofrequency neurotomy. Additionally, a recent systematic review of sacroiliac joint injections showed Level III or fair evidence. The sacroiliac joint, a critical axial joint linking the spine and pelvis, contributes to low back pain. Its complex innervation pattern varies among individuals. Sacroiliac joint dysfunction, causing pain and stiffness, arises from diverse factors.The present systematic review and meta-analysis aimed to evaluate radiofrequency neurotomy's effectiveness for sacroiliac joint pain management by applying rigorous methodology, considering both RCTs and observational studies. Despite methodological disparities, the evidence from this review, supported by changes in pain scores and functional improvement, suggests Level III evidence with fair recommendation for radiofrequency neurotomy as a treatment option. The review's strengths include its comprehensive approach and quality assessment. However, limitations persist, including variations in criteria and technical factors, underscoring the need for further high-quality studies in real-world scenarios.
