BACKGROUND
Infantile hemangioma (IH) is the most common benign vascular tumor of infancy. Propranolol is considered first-line therapy for IH. However, it is associated with side effects. Therefore, there was a need for alternative therapy. Atenolol, a selective b1-blocker may be free from such side effects. Hence, the present study aims to develop a more accurate estimate of the safety and efficacy of atenolol compared to propranolol in the treatment of IH.
METHODOLOGY
A search of various literature databases (PubMed, Embase, Ovid, Scopus, Cochrane Central, CINAHL, Web of Science, and Google Scholar) was done to identify studies which compared propranolol versus atenolol in the treatment of IH. The combined odds ratio along with corresponding 95% confidence intervals (CIs) were evaluated using a fixed-effects model.
RESULTS
A total of 300 articles were screened of which five studies including 116 patients in atenolol arm and 138 patients in the propranolol arm were analyzed. Atenolol was comparable to propranolol in terms of efficacy as no significant difference was seen between both the treatment arms in terms of hemangioma activity score (mean difference 0.25 [95% CI;‒0.21, 0.71]) and complete response (odds ratio [OR] =0.43; 95% CI; 0.17, 1.11; = 0.08,). Atenolol therapy was better than propranolol in terms of safety, i.e., serious/potentially serious side effect, (OR = 0.11; 95% CI; 0.02, 0.51; = 0.005) and wheezing/bronchial hyperreactivity (OR = 0.11; 95% CI; 0.02, 0.51; = 0.005).
CONCLUSION
The present meta-analysis provides evidence that atenolol has got a comparable efficacy and better safety profile with propranolol.

BACKGROUND
Infantile hemangioma (IH) is common in children, which may bring about cosmetically disfiguring, functional impairment, and exhibiting complications. There had been various therapies and we aimed to assess the efficacy and adverse effects of different therapies through network meta-analysis.
METHODS
We searched PubMed, Embase, Cochrane Library and Web of Science (from database inception to April 11, 2020) for studies assessing the efficacy, success rate and adverse effects. Direct pairwise comparison and a network meta-analysis under random effects were performed. We also assessed the ranking probability.
FINDINGS
A total of 30 randomized clinical trials with more than 20 different therapeutic regimens were identified. Treatment combined propranolol orally with laser could improve the curative effect than monotherapy. Laser with topical β blockers showed more efficiency than others whether in children under 6 months or not. The long-pulsed dye laser might be the best laser therapy. A higher dose and a longer treatment duration of propranolol orally achieved a higher success rate and increased side effects. Plus pulse dye laser with propranolol had the lowest incidence of adverse reactions, such as ulcer, color sink and color reduction.
INTERPRETATION
A combination of β blockers and laser might be the first-line treatment of IHs and a longer pulsed dye laser is preferred.

Meta-Analysis Review
BACKGROUND & AIMS
Non-selective β blockers (NSBBs) may negatively influence renal function through decreasing heart rate and cardiac output. This study aimed to systematically investigate their association.
METHODS
PubMed, EMBASE, and Cochrane library databases were searched to identify all relevant studies evaluating the association of NSBBs with renal dysfunction in cirrhotic patients. Unadjusted and adjusted data were separately extracted. Odds ratios (ORs) and hazard ratios (HRs) were pooled. Subgroup meta-analyses were performed according to the proportions of ascites and Child-Pugh class B/C and the mean model for end-stage liver disease (MELD) score. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework.
RESULTS
Fourteen studies were finally included. Based on unadjusted data, NSBBs significantly increased the risk of developing renal dysfunction (OR = 1.49; = 0.03), and this association remained significant in subgroup analyses of studies where the proportions of ascites was >70% and Child-Pugh class B/C was 100%. Based on adjusted data with propensity score matching (adjusted OR = 0.61; = 0.08) and multivariable regression modelling (adjusted HR = 0.86; = 0.713), NSBBs did not increase the risk of developing renal dysfunction, and this association remained not significant in subgroup analyses of studies where the proportions of ascites was >70% and <70%, the proportion of Child-Pugh class B/C was <100%, and the mean MELD score was <15. The quality of evidence was very low for all meta-analyses.
CONCLUSIONS
NSBBs may not be associated with the development of renal dysfunction in liver cirrhosis. However, more evidence is required to clarify their association in specific populations.

Review
BACKGROUND
Post-traumatic stress disorder (PTSD) is a severe and debilitating condition. Several pharmacological interventions have been proposed with the aim to prevent or mitigate it. These interventions should balance efficacy and tolerability, given that not all individuals exposed to a traumatic event will develop PTSD. There are different possible approaches to preventing PTSD; universal prevention is aimed at individuals at risk of developing PTSD on the basis of having been exposed to a traumatic event, irrespective of whether they are showing signs of psychological difficulties.
OBJECTIVES
To assess the efficacy and acceptability of pharmacological interventions for universal prevention of PTSD in adults exposed to a traumatic event.
SEARCH METHODS
We searched the Cochrane Common Mental Disorders Controlled Trial Register (CCMDCTR), CENTRAL, MEDLINE, Embase, two other databases and two trials registers (November 2020). We checked the reference lists of all included studies and relevant systematic reviews. The search was last updated on 13 November 2020.
SELECTION CRITERIA
We included randomised clinical trials on adults exposed to any kind of traumatic event. We considered comparisons of any medication with placebo or with another medication. We excluded trials that investigated medications as an augmentation to psychotherapy.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodological procedures. In a random-effects model, we analysed dichotomous data as risk ratios (RR) and number needed to treat for an additional beneficial/harmful outcome (NNTB/NNTH). We analysed continuous data as mean differences (MD) or standardised mean differences (SMD).
MAIN RESULTS
We included 13 studies which considered eight interventions (hydrocortisone, propranolol, dexamethasone, omega-3 fatty acids, gabapentin, paroxetine, PulmoCare enteral formula, Oxepa enteral formula and 5-hydroxytryptophan) and involved 2023 participants, with a single trial contributing 1244 participants. Eight studies enrolled participants from emergency departments or trauma centres or similar settings. Participants were exposed to a range of both intentional and unintentional traumatic events. Five studies considered participants in the context of intensive care units with traumatic events consisting of severe physical illness. Our concerns about risk of bias in the included studies were mostly due to high attrition and possible selective reporting. We could meta-analyse data for two comparisons: hydrocortisone versus placebo, but limited to secondary outcomes; and propranolol versus placebo. No study compared hydrocortisone to placebo at the primary endpoint of three months after the traumatic event. The evidence on whether propranolol was more effective in reducing the severity of PTSD symptoms compared to placebo at three months after the traumatic event is inconclusive, because of serious risk of bias amongst the included studies, serious inconsistency amongst the studies' results, and very serious imprecision of the estimate of effect (SMD -0.51, 95% confidence interval (CI) -1.61 to 0.59; I = 83%; 3 studies, 86 participants; very low-certainty evidence). No study provided data on dropout rates due to side effects at three months post-traumatic event. The evidence on whether propranolol was more effective than placebo in reducing the probability of experiencing PTSD at three months after the traumatic event is inconclusive, because of serious risk of bias amongst the included studies, and very serious imprecision of the estimate of effect (RR 0.77, 95% CI 0.31 to 1.92; 3 studies, 88 participants; very low-certainty evidence). No study assessed functional disability or quality of life. Only one study compared gabapentin to placebo at the primary endpoint of three months after the traumatic event, with inconclusive evidence in terms of both PTSD severity and probability of experiencing PTSD, because of imprecision of the effect estimate, serious risk of bias and serious imprecision (very low-certainty evidence). We found no data on dropout rates due to side effects, functional disability or quality of life. For the remaining comparisons, the available data are inconclusive or missing in terms of PTSD severity reduction and dropout rates due to adverse events. No study assessed functional disability.
AUTHORS' CONCLUSIONS
This review provides uncertain evidence only regarding the use of hydrocortisone, propranolol, dexamethasone, omega-3 fatty acids, gabapentin, paroxetine, PulmoCare formula, Oxepa formula, or 5-hydroxytryptophan as universal PTSD prevention strategies. Future research might benefit from larger samples, better reporting of side effects and inclusion of quality of life and functioning measures.

Review
BACKGROUND
Essential tremor (ET) is one of the most common tremor disorders in the world. Despite this, only one medication, propranolol, is approved by the Food and Drug Administration to treat it.
OBJECTIVES
We analyzed controlled clinical trials in ET, spanning the last 50 years, to identify potential shortcomings in the therapeutic clinical pipeline.
METHODS
Outcomes reviewed included demographics (specifically gender and race), therapeutic modalities, funding information, location of research, and trends over time. Clinical trials published in English were identified in scientific databases (Pubmed, SCOPUS, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform from 1970 through December 2021. Included trials were prospective, either single- or double-blinded (including blinded video assessments for surgical trials), with change in limb, head, or voice tremor as the primary outcome measure.
RESULTS
One hundred and eighty-six controlled clinical trials were accepted for extraction, including 4207 patients. Of the 145 trials that included gender, males comprised 59% of the patient population. Only 6.4% of studies provided racial demographics; in these studies, 70.5% of patients were Caucasian. The most common therapeutic modality over the past 50 years was "pharmaceutical" (56%), and the most common pharmaceutical studied was propranolol (32%). 41% of clinical trials reported no specific funding.
CONCLUSIONS
Future efforts should focus on increasing funding for clinical trial research in ET worldwide, and trials should be designed to be more inclusive of disadvantaged minorities.

Meta-Analysis
OBJECTIVE
There is no medical treatment proven to limit abdominal aortic aneurysm (AAA) progression. This systematic review aimed to summarise available trial evidence on the efficacy of pharmacotherapy in limiting AAA growth and AAA-related events.
METHODS
A systematic literature search was performed to examine the efficacy of pharmacotherapy in reducing AAA growth and AAA-related events. Pubmed, Embase (Excerpta Medica Database), and the Cochrane library were searched from March, 1999 to March 29, 2022. AAA growth (mm/year) in the intervention and control groups was expressed as mean and standard deviation (SD). The results of AAA growth were expressed as mean difference (MD) and its 95% confidence interval (95% CI). Odds ratios (ORs) were calculated for the AAA-related events.Heterogeneity was quantified using the I statistic. Forest plots were created to show the pooled results of each outcome.
OUTCOMES
A total of 1373 articles were found in different databases according to the search strategy, and 10 articles were identified by hand searching. A total of 26 articles were included in our systematic review after the screening. For the studies of metformin, the meta-analysis demonstrated that metformin use was associated with a lower AAA growth rate (MD: -0.81 mm/y, 95% CI: -1.19 to -0.42, P < 0.0001, I = 87%), Metformin use also was related to the lower rates of AAA-related events (OR: 0.53, 95% CI: 0.36 to 0.76, P = 0.0007, I = 60%). The hypotensive drugs of the studies mainly included angiotensin-converting enzyme inhibitors (ACEI), angiotensin II type 1 receptor blockers (ARB), and propranolol. The overall meta-analysis of blood pressure-lowering drugs reported no significant effect in limiting the AAA growth (MD: 0.31mm/year, 95%CI: -0.03 to 0.65, P = 0.07, I = 66%) and AAA-related events (OR: 1.33, 95%CI: 0.76 to 2.32, P = 0.32, I = 98%), In the subgroup analysis of the hypotensive drugs, the ACEI/ARB and propranolol also showed no significant in reducing the AAA growth and AAA-related events. The meta-analysis of the antibiotics demonstrated that the antibiotics were not associated with a lower AAA growth rate (MD: -0.27 mm/y, 95% CI: -0.88 to 0.34, P = 0.39, I = 77%) and AAA-related events (OR: 0.94, 95%CI: 0.65 to 1.35, P = 0.72, I = 0%). The results of statins also showed no significant effect in limiting AAA growth (MD: -1.11mm/year, 95%CI: -2.38 to 0.16, P = 0.09, I = 96%) and AAA-related events (OR: 0.53, 95%CI: 0.26 to 1.06, P = 0.07, I = 92%).
CONCLUSION
In conclusion, effective pharmacotherapy for AAA was still lacking. Although the meta-analysis showed that metformin use was associated with lower AAA growth and AAA-related events, all of the included studies about metformin were cohort studies or case-control studies. More randomized controlled trials (RCTs) are needed for further verification.

Meta-Analysis
BACKGROUND
Chronic migraine can be a profoundly disabling disorder that may be treated with preventive medications. However, uncertainty remains as to which preventive medication is the most effective. We present a network meta-analysis to determine the effectiveness and rank of preventive drugs for chronic migraine in adults.
METHODS
We identified, reviewed, and extracted data from randomised controlled trials (RCTs) of preventive drugs for chronic migraine with at least 200 participants. Data were analysed using network meta-analysis.
FINDINGS
We included 12 RCTs of six medications (Eptinezumab, Erenumab, Fremanezumab, Galcanezumab, Onabotulinumtoxin A, and Topiramate) compared to placebo or each other. All drugs effectively reduced monthly headache and migraine days compared with placebo. The most effective drug for monthly headache days was Eptinezumab 300mg, with a mean difference of -2.46 days, 95% Credible Interval (CrI): -3.23 to -1.69. On the Surface Under the Cumulative Ranking Area (SUCRA) analysis, the probability that Eptinezumab 300mg was ranked highest was 0.82. For monthly migraine days, the most effective medication was Fremanezumab-monthly, with a mean difference: -2.77 days, 95% CrI: -3.36 to -2.17, and 0.98 probability of being ranked the highest. All included drugs, except Topiramate, improved headache-related quality of life. No eligible studies were identified for the other common preventive oral medications such as Amitriptyline, Candesartan, and Propranolol. The main reasons were that the studies did not define chronic migraine, were undertaken before the definition of chronic migraine, or were too small.
INTERPRETATION
All six medications were more effective than the placebo on monthly headache and migraine days. The absolute differences in the number of headache/migraine days are, at best, modest. No evidence was found to determine the relative effectiveness of the six included drugs with other oral preventive medications.

BACKGROUND AND AIM
Bleeding from gastric varices is a catastrophic event and poses difficulty in management. The efficacy and safety of cyanoacrylate injection remain unclear. We performed a systematic review and meta-analysis to evaluate the effect of endoscopic cyanoacrylate injection in the management of gastric varices.
METHODS
We conducted a comprehensive search of MEDLINE, Embase, Web of Science, Scopus databases, and Cochrane Database of Systematic Reviews through November 2020 and manually reviewed the literature. Trial-specific risk ratios (RRs) were estimated and pooled using random-effect model meta-analysis.
RESULTS
We included seven randomized controlled trials (six for secondary prophylaxis and one for primary prophylaxis) at low risk of bias in which 126 deaths were reported among 583 patients with gastric varices. All studies reported the use of N-butyl-2-cyanoacrylate glue. Cyanoacrylate use was associated with significantly lower all-cause mortality (RR, 0.59; 95% confidence interval [CI], 0.36-0.98; I = 41%) and rebleeding rate after hemostasis (RR, 0.49; 95% CI, 0.35-0.68, I = 0%) compared with any other treatment approach not involving cyanoacrylate. When cyanoacrylate was compared with each individual treatment approach (propranolol only, band ligation, sclerotherapy with alcohol or ethanolamine), data comprised sparse limited comparative conclusions. The use of cyanoacrylate injection was not associated with an increase in serious adverse events. The quality of evidence is moderate, graded down due to the small number of events and wide CIs.
CONCLUSION
The use of endoscopic cyanoacrylate injection therapy for gastric varices may be associated with lower all-cause mortality and better hemostasis compared with other therapies.

BACKGROUND
Visual snow syndrome is a debilitating disorder characterized by tiny flickering dots (like TV static) in the entire visual field and a set of accompanying visual (palinopsia, enhanced entoptic phenomena, photophobia, nyctalopia), nonvisual (e.g. tinnitus) and nonperceptional (e.g. concentration problems, irritability) symptoms. Its pathophysiology is enigmatic and therapy is often frustrating.
OBJECTIVES
To summarize our current understanding of pathophysiology and treatment of visual snow syndrome.
METHODS
A systematic search of PubMed database was performed using the key word "visual snow" and predefined in- and exclusion criteria. The results were stratified into "treatment" and "pathophysiology." Additionally, we conducted a search with the key words "persistent migraine aura" and "persistent visual aura" and screened for mis-diagnosed patients actually fulfilling the criteria for visual snow syndrome. The reference lists of most publications and any other relevant articles known to the authors were also reviewed and added if applicable.
RESULTS
From the 50 original papers found by searching for "visual snow," 21 were included according to the inclusion and exclusion criteria. Additional four publications came searching for "persistent migraine aura" or "persistent visual aura." Further publications derived from literature references resulting in a total of 20 articles for pathophysiology and 15 for treatment with some overlaps. Regarding pathophysiology, hyperexcitability of the visual cortex and a processing problem of higher order visual function are assumed, but the location is still in discussion. In particular, it is unclear if the primary visual cortex, the visual association cortex or the thalamocortical pathway is involved. Regarding treatment, data is available on a total of 153 VSS patients with medication mentioned for 54 resulting in a total of 136 trials. From the 44 different medications tried, only eight were effective at least once. The best data is available for lamotrigine being effective in 8/36 (22.2%, including one total response and no worsening), followed by topiramate being effective in 2/13 (15.4%, no total response and one worsening). The only other medication resulting in worsening of VSS was amitriptyline according to our literature review. The others reported to be effective at least once were valproate, propranolol, verapamil, baclofen, naproxen and sertraline. The nonpharmacological approach using color filters of the yellow-blue color spectrum might also be helpful in some patients.
CONCLUSIONS
Visual snow syndrome is still far from being fully understood. In respect of pathophysiology, a disorder of visual processing is likely. The best pharmacological evidence exists for lamotrigine, which can be discussed off-label. As nonpharmacological option, patients might benefit from tinted glasses for everyday use.

BACKGROUND
Flushing and erythema are frequent skin symptoms in rosacea. Because their adequate treatment remains a clinical challenge, new treatment options are explored, such as oral β-blockers.
OBJECTIVES
To evaluate the efficacy of oral β-blockers for rosacea-associated facial flushing and erythema.
METHODS
PubMed, Embase, Web of Science, and Cochrane Library were systematically searched, including studies providing original data on the efficacy of oral β-blockers in rosacea patients with facial flushing and/or persistent erythema. Risk of bias was assessed using the Cochrane Risk of Bias tool, Newcastle-Ottawa scale, and Quality in Prognosis Studies tool.
RESULTS
Nine studies evaluating the use of carvedilol, propranolol, nadolol, and β-blockers in general were included. Articles studying carvedilol and propranolol showed a large reduction of erythema and flushing during treatment with a rapid onset of symptom control. Bradycardia and hypotension were the most commonly described adverse events.
LIMITATIONS
Most studies had a retrospective design with a small sample size, and outcome measurement was often subjective.
CONCLUSIONS
Oral β-blockers could be an effective treatment option for patients with rosacea with facial erythema and flushing that does not respond to conventional therapy. Larger prospective trials with objective outcome assessment are needed to validate the promising results of these studies.
