Meta-Analysis Review
BACKGROUND
Breast surgeries aim to restore the natural appearance of the breasts with acceptable functional and cosmetic outcomes. However, these surgical procedures may be associated with considerable adverse events. The present systematic review and meta-analysis was designed to reveal the functional and aesthetic outcomes of botulinum toxins (BTX) injection in patients subjected to breast surgeries.
METHODS
A literature review was performed up to 21 September 2022. All clinical studies included patients older than 18 years old and treated with BTX injection for breast surgeries were included.
RESULTS
The present study included 12 articles, encompassing 496 patients. The average dosage of BTX injection ranged from 20 to 100 units. Injecting BTX significantly reduced the mean post-operative opioid analgesics usage (SMD -1.577; 95% -2.087, -1.067; P < 0.001) and the risk of severe animation deformity (RR 12.37; 95% 1.76, 86.66; P = 0.01). There was a statistically significant higher mean expansion volume per visit in the BTX injection group (SMD 1.166; 95% 0.313, 2.018; P = 0.007). There was no statistically significant impact of BTX injection on the risk of surgical site infection (RR 0.59; 95% 0.15, 2.34; P = 0.45) and seroma (RR 0.51; 95% 0.03, 10.15; P = 0.66).
CONCLUSIONS
The present study revealed the potential benefits of BTX injection in breast surgeries. This included reduced post-operative analgesics, as well as the risk of severe animation deformity. This was accomplished with increased expansion volume per visit and a similar risk of BTX injection-related complications.

OBJECTIVE
Post-stroke spasticity (PSS) is a common complication in stroke survivors, causing severe burden to patients living with it. The aim of this review was to conduct a cost-effectiveness analysis (CEA) of the treatment of post-stroke spasticity, in adults, with abobotulinumtoxinA compared to the best supportive care, based on results from a systematic literature review. Given that abobotulinumtoxinA (aboBoNT-A) is always accompanied by the best supportive care treatment, the CEA compared aboBoNT-A plus the best supportive care with the best supportive care alone.
METHODS
A systematic literature review in EMBASE (including Medline and PubMed), Scopus, and other sources (Google Scholar) was conducted. Articles of all types, providing information on the costs and/or effectiveness measures for the current treatments of PSS in adults were included. The synthesis of information from the review provided the parameters for the design of a cost-effectiveness analysis of the mentioned treatment of interest. The societal perspective was compared to a perspective where only direct costs were observed.
RESULTS
In total, 532 abstracts were screened. Full information was revised from 40 papers and 13 of these were selected as core papers for full data extraction. Data from the core publications formed the basis for the development of a cost-effectiveness model. In all the included papers physiotherapy was the best supportive care treatment (SoC). The cost-effectiveness analysis showed that even in the most conservative scenario, assuming the worst case scenario, the probability of a cost per quality-adjusted life-year (QALY) gained below €40,000, for aboBoNT-A together with physiotherapy is above 0.8, and with certainty below €50,000/QALY when either a direct costs, or a societal perspective was taken. On average, the probabilistic model obtains a negative mean incremental cost-effectiveness ratio of around -15,000 €/QALY.
CONCLUSION
The cost-effectiveness analyses show that aboBoNT-A together with physiotherapy would be a cost-effective treatment compared with physiotherapy alone, independently of the perspective considered.

Review
BACKGROUND
The optimal diagnostic and treatment algorithm for patients with suspected thoracic outlet syndrome (TOS) remains challenging. Botulinum toxin (BTX) muscle injections have been suggested to shrink muscles in the thoracic outlet reducing neurovascular compression. This systematic review evaluates the diagnostic and therapeutic value of BTX injections in TOS.
METHODS
A systematic review of studies reporting BTX as a diagnostic or therapeutic tool in TOS (or pectoralis minor syndrome as TOS subtype) was conducted in PubMed, Embase, and CENTRAL databases on May 26, 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was followed. Primary end point was symptom reduction after primary procedure. Secondary end points were symptom reduction after repeated procedures, the degree of symptom reduction, complications, and duration of clinical effect.
RESULTS
Eight studies (1 randomized controlled trial [RCT], 1 prospective cohort study, and 6 retrospective cohort studies) were included reporting 716 procedures in at least 497 patients (at minimum 350 primary and 25 repeated procedures, residual unclear) diagnosed with presumably only neurogenic TOS. Except for the RCT, the methodological quality was fair to poor. All studies were designed on an intention to treat basis, one also investigated BTX as a diagnostic tool to differentiate pectoralis minor syndrome from costoclavicular compression. Reduction of symptoms was reported in 46-63% of primary procedures; no significant difference was found in the RCT. The effect of repeated procedures could not be determined. Degree of symptom reduction was reported by up to 30-42% on the Short-form McGill Pain scale and up to 40 mm on a visual analog scale. Complication rates varied among studies, no major complications were reported. Symptom relief ranged from 1 to 6 months.
CONCLUSIONS
Based on limited quality evidence, BTX may provide short-lasting symptom relief in some neurogenic TOS patients but remains overall undecided. The role of BTX for treatment of vascular TOS and as a diagnostic tool in TOS is currently unexploited.

Review
The efficacy of many non-surgical treatments for Peyronie's disease is unclear. This systematic review aims to critically assess the currently available options and provide a recommendation for treatment based on this. A systematic literature search utilising the Medline (Pubmed), Embase, global health and Cochrane library databases was conducted up to May 2021. All randomised controlled trials assessing non-surgical treatment modalities for Peyronie's Disease were included. Individual study risk of bias was evaluated using the Cochrane tool and GRADE was used to assess evidence strength. Outcome measures were the change in penile curvature (degrees), plaque size (volume or size), International Index of Erectile Function score, pain scores and change in penile length. Prospero registration number: CRD42017064618. Amongst the 5549 articles identified, 41 studies (42 reports) were included. Seven different oral treatment options including vitamin E supplementation showed evidence for improving outcomes such as penile curvature and plaque size. Of the intralesional treatments, Collagenase Clostridium Histolyticum showed evidence for improving penile curvature (Range: 16.3-17 degrees, moderate level certainty of evidence). Intralesional Interferon demonstrated some improvement in curvature (Range: 12-13.5 degrees), plaque size (Range: 1.67-2.2 cm) and pain, whilst intralesional calcium channel blockers such as Verapamil showed variable evidence for changes in the plaque size and pain. Extracorporeal Shockwave Therapy consistently demonstrated evidence for improving penile pain in stable disease, and two mechanical traction devices improved curvature. Iontophoresis, topical medications, and combination therapies did not demonstrate any consistent improvements in outcome measures. Intralesional options demonstrate the best potential. Overall, results varied with few high-quality randomised trials present.
