Review
This review provides an up-to-date literature account on the efficacy of Botulinum toxin treatment for common motor disorders of Parkinson Disease. The reviewed disorders include the common motor disorders in PD such as tremor, focal foot dystonia, rigidity and freezing of gait (FOG). In the area of Parkinson tremor, two newly described evaluation/injection techniques (Yale method in USA and Western University method in Canada) offer efficacy with low incidence of hand and finger weakness as side effects. Blinded studies conducted on foot dystonia of PD indicate that botulinum toxin injections into toe flexors are efficacious in alleviating this form of dystonia. Small, blinded studies suggest improvement of Parkinson rigidity after botulinum toxin injection; proof of this claim, however, requires information from larger, blinded clinical trials. In FOG, the improvement reported in open label studies could not be substantiated in blinded investigations. However, there is room for further controlled studies that include the proximal lower limb muscles in the injection plan and/or use higher doses of the injected toxin for this indication.

Meta-Analysis
OBJECTIVE
To evaluate the efficacy and safety of botulinum toxin (BTX) for motor dysfunction in Parkinson's disease (PD).
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
Searches of PubMed, EMBASE and the Cochrane Library, from database inception to 20 October 2022.
ELIGIBILITY CRITERIA
Studies reported in English with adult PD patients treated with BTX.
DATA EXTRACTION AND SYNTHESIS
Primary outcomes were United Parkinson's Disease Rate Scale Section (UPDRS) III (or its items) and Visual Analogue Scale (VAS). Secondary outcomes were UPDRS-II (or its items), Freezing of Gait Questionnaire (FOG-Q), Timed Up and Go test (TUG) and treatment-related adverse events (TRAEs). Mean difference (MD) or standardised MD (SMD) before and after treatment with 95% CIs were used for continuous variables and risk ratios (RRs) with 95% CIs was used for TRAEs.
RESULTS
Six randomised controlled trials (RCTs) and six non-RCTs (case series) were included (n=224 participants, n=165). No significant difference was found in pooled results of UPDRS-III (available in four RCTs and two non-RCTs, SMD=-0.19, 95% CI -0.98 to 0.60), UPDRS-II (four RCTs and one non-RCT, SMD=-0.55, 95% CI -1.22 to 0.13), FOG-Q (one RCT and one non-RCT, SMD=0.53, 95% CI -1.93 to 2.98) or the risk of TRAEs (five RCTs, RR 0.87, 95% CI 0.37 to 2.01). Significant decreases were found in pooled VAS score (three RCTs and five non-RCTs, MD=-2.14, 95% CI -3.05 to -1.23) and TUG (MD=-2.06, 95% CI -2.91 to -1.20) after BTX treatment.
CONCLUSIONS
BTX may not be associated with motor symptoms alleviation, although it benefits pain alleviation and functional mobility improvement.

Dermatologic Surgery : Official... Nov 2023Many reports have described the use of botulinum toxin (BTX) in the treatment of scalp conditions, but no studies have synthesized these collective findings.
BACKGROUND
Many reports have described the use of botulinum toxin (BTX) in the treatment of scalp conditions, but no studies have synthesized these collective findings.
OBJECTIVE
We conducted a systematic review to summarize the scalp conditions for which treatment with BTX has been described.
METHODS
We searched PubMed/MEDLINE and Scopus for articles in English published before November 1, 2022, using the keywords "hair" or "scalp" and BTX-related search terms. Articles that described patients who received injections of BTX for the management of scalp conditions were included.
RESULTS
Twenty-four original articles (12 case reports, 9 clinical trials, and 3 case series) were identified that described 309 patients with a scalp condition treated with BTX. Androgenetic alopecia, craniofacial hyperhidrosis, and scalp hyperseborrhea had the most robust data supporting the clinical efficacy of BTX.
CONCLUSION
The current quality of evidence is highly variable and, for many conditions, limited to small observational studies. Botulinum toxin may be a promising therapeutic option for patients with various scalp conditions, but future studies are needed to better understand its efficacy and safety.

Meta-Analysis Review
INTRODUCTION AND HYPOTHESIS
This systematic review and meta-analysis aim to evaluate the outcomes between SNM and BTX in the treatment of refractory OAB.
METHODS
PubMed, Embase, and CENTRAL were comprehensively searched from their inception to December 2019. Randomized and nonrandomized controlled trials evaluating OAB patients who underwent SNM and BTX were included. Data extraction and quality assessment were conducted by two independent reviewers. The outcomes, side effects, and cost-effectiveness values of both procedures were compared in meta-analysis.
RESULTS
This review involved six articles (2629 patients). Specifically, three articles were based on the same trial, and the other studies were retrospective cohort studies. No significant difference was found in successful treatment between BTX and SNM at 6 months after procedures [risk ratio (RR) = 0.93, 95% confidence interval (CI) 0.63-1.39]. BTX exhibited a significantly higher total adverse event rate than SNM through 6 months (RR = 1.55, 95% CI 1.28-1.88). Patients suffered more urinary tract infection (UTI) risk under BTX injection at the early stage (RR = 1.58, 95% CI 1.10-2.25); however, the difference in UTI events was not significant between the two groups (RR = 1.13, 95% CI 1.10-2.25) during the period of 7-12 months postoperatively. Obviously, the short-term cost (1-2 years) of BTX was significantly lower than that of the SNM procedure.
CONCLUSIONS
Both treatments were effective; however, because of the high complication rate of BTX, it may not be a better way to treat refractory OAB than SNM, although BTX is more cost-effective for short-term treatment at present.

Meta-Analysis
PURPOSE
The objective of this systematic review and meta-analysis was to synthesize the available randomized controlled trial data comparing needle fasciotomy and collagenase treatment for single-digit Dupuytren contractures with a minimum of 3-year follow-up and determine whether one treatment is superior regarding contracture correction and functional outcomes.
METHODS
A systematic review and meta-analysis was conducted by searching four databases for randomized controlled trials investigating the single-digit treatment outcomes for Dupuytren contracture comparing collagenase treatment and needle fasciotomy with a minimum of 3-year follow-up. The risk of bias of included studies was assessed using the Cochrane risk-of-bias tool. A meta-analysis was performed using a random effects model in anticipation of unobserved heterogeneity. The primary outcome measure was contracture recurrence. Secondary outcome measures included final fixed flexion contracture (FFC), Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores, and Unité Rhumatologique des Affections de la Main (URAM) scores.
RESULTS
After screening 264 articles, 4 randomized clinical trials were eligible for final inclusion. One trial had a high risk of bias, and two trials had some concern for bias. The final meta-analysis included 347 patients, 169 who underwent collagenase treatment and 178 who underwent needle fasciotomy. No significant differences were noted between the groups in contracture recurrence, FFC, and URAM scores. The pooled data showed a higher QuickDASH score in the collagenase treatment group compared with the needle fasciotomy group, but the observed difference was less than what would be expected to be clinically relevant.
CONCLUSIONS
Needle fasciotomy and collagenase treatment have similar outcomes with regards to contracture recurrence, final FFC, QuickDASH scores, and URAM scores for the single-digit treatment for Dupuytren contracture at a minimum of 3-year follow-up. Relevant factors that may be considered during the shared decision-making process for treatment selection include surgeon and patient preferences, costs of treatment, and the disparate complication profiles of these two treatments.

Meta-Analysis Review
Specific proteases capable of degrading native triple helical or denatured collagen have been required for many years and have a large spectrum of applications. There are few complete reports that fully uncover production, characterization and purification of fungi collagenases. In this review, authors searched through four scientific on line data bases using the following keywords (collagenolytic OR collagenase) AND (fungi OR fungus OR fungal) AND (production OR synthesis OR synthesize) AND (characterization). Scientific criteria were adopted in this review to classify found articles by score (from 0 to 10). After exclusion criteria, 21 articles were selected. None obtained the maximum of 10 points defined by the methodology, which indicates a deficiency in studies dealing simultaneously with production, characterization and purification of collagenase by fungi. Among microorganisms studied the non-pathogenic fungi Penicillium aurantiogriseum and Rhizoctonia solani stood out in volumetric and specific collagenase activity. The only article found that made sequencing of a true collagenase showed 100% homology with several metalloproteinases fungi. A clear gap in literature about collagenase production by fungi was verified, which prevents further development in the area and increases the need for further studies, particularly full characterization of fungal collagenases with high specificity to collagen.

Review
AIMS
Dupuytren's contracture is a benign, myoproliferative condition affecting the palmar fascia that results in progressive contractures of the fingers. Despite increased knowledge of the cellular and connective tissue changes involved, neither a cure nor an optimum form of treatment exists. The aim of this systematic review was to summarize the best available evidence on the management of this condition.
MATERIALS AND METHODS
A comprehensive database search for randomized controlled trials (RCTs) was performed until August 2017. We studied RCTs comparing open fasciectomy with percutaneous needle aponeurotomy (PNA), collagenase clostridium histolyticum (CCH) with placebo, and CCH with PNA, in addition to adjuvant treatments aiming to improve the outcome of open fasciectomy. A total of 20 studies, involving 1584 patients, were included.
RESULTS
PNA tended to provide higher patient satisfaction with fewer adverse events, but had a higher rate of recurrence compared with limited fasciectomy. Although efficacious, treatment with CCH had notable recurrence rates and a high rate of transient adverse events. Recent comparative studies have shown no difference in clinical outcome between patients treated with PNA and those treated with CCH.
CONCLUSION
Currently there remains limited evidence to guide the management of patients with Dupuytren's contracture. Cite this article: Bone Joint J 2018;100-B:1138-45.

Meta-Analysis Review
Background. Matrix metalloproteinases (MMPs) are considered to play an important role during tissue remodeling and extracellular matrix degradation. And functional polymorphisms in MMPs genes have been reported to be associated with the increased risk of periodontitis. Recently, many studies have investigated the association between MMPs polymorphisms and periodontitis risk. However, the results remain inconclusive. In order to quantify the influence of MMPs polymorphisms on the susceptibility to periodontitis, we performed a meta-analysis and systematic review. Results. Overall, this comprehensive meta-analysis included a total of 17 related studies, including 2399 cases and 2002 healthy control subjects. Our results revealed that although studies of the association between MMP-8 -799 C/T variant and the susceptibility to periodontitis have not yielded consistent results, MMP-1 (-1607 1G/2G, -519 A/G, and -422 A/T), MMP-2 (-1575 G/A, -1306 C/T, -790 T/G, and -735 C/T), MMP-3 (-1171 5A/6A), MMP-8 (-381 A/G and +17 C/G), MMP-9 (-1562 C/T and +279 R/Q), and MMP-12 (-357 Asn/Ser), as well as MMP-13 (-77 A/G, 11A/12A) SNPs are not related to periodontitis risk. Conclusions. No association of these common MMPs variants with the susceptibility to periodontitis was found; however, further larger-scale and multiethnic genetic studies on this topic are expected to be conducted to validate our results.

Review
The purpose of this review was to summarize and compare the efficacy among surgical interventions in terms of symptomatic relief in patients with interstitial cystitis/bladder pain syndrome (IC/BPS). The review protocol was published on PROSPERO. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist was followed. Following database search, a narrative synthesis was performed. Data pertaining symptom scores, pain levels, and voiding frequency following surgery were summarized by calculating percentage change in these parameters. Multiple surgical treatments were identified. These included injections of hyaluronic acid (HA), botulinum toxin A (Botox A), triamcinolone, resiniferatoxin (RTX), platelet-rich plasma, and 50% dimethyl sulfoxide (DMSO) solution, neuromodulation, hydrodistension (HD), resection/fulguration of Hunner lesions, resection of ilioinguinal and iliohypogastric nerves, reconstructive surgery, and cystectomy. This review found no evidence suggesting that HD and RTX injections can ameliorate IC/BPS symptoms. Current evidence suggests that sacral neuromodulation, cystectomy, and transurethral resection/fulguration of Hunner lesions could lead to symptomatic relief in IC/BPS. Further research into the efficacy of Botox A, triamcinolone, 50% DMSO solution, and HA instillations is required. However, the best treatment options cannot be reliably stated due to the low level of evidence of the studies identified. Further research should report outcomes for Hunner-type IC and BPS separately given their differing histopathological characteristics. Performing high-quality randomized controlled trials could be hindered by the low prevalence of the condition and a small proportion of patients progressing to surgery.

Review
The objective of this study was to realize a scoping review the literature in order to identify the profile of DPSCs isolation and analyze the possible risk factors that could change the native behavior of these cells. An initial search was conducted using the following MeSH terms: "(dental pulp stem cell [MeSH])"; "(dental pulp [MeSH])" AND "(stem cell [MeSH])"; "("dental pulp stem cell" [MeSH]")". The electronic search was done without date restriction up to and including April 2014, in PubMed, Scopus, Scielo and ISI Web of Knowledge databases. Studies were submitted to inclusion and exclusion criteria and 222 articles were included. Data showed that over the past 15 years many studies have been conducted using DPSCs. However this is the first systematic review regarding the isolation of stem cell, and more specifically of dental pulp stem cells. The isolation of dental pulp stem cells showed great variability, hampering the development of standard protocols to achieve in vitro dental pulp stem cells with similar characteristics. This scoping review combined, for the first time, the methodologies used for dental pulp stem isolation, highlighting the most frequently used.
