STUDY DESIGN
Systematic review and meta-analysis.
OBJECTIVE
The objective of this study was to conduct a systematic review to assess the comparative effectiveness and safety of high-dose methylprednisolone sodium succinate (MPSS) versus no pharmacological treatment in patients with traumatic spinal cord injury (SCI).
METHODS
A systematic search was performed in PubMed and the Cochrane Collaboration Library for literature published between January 1956 and June 17, 2015. Included studies were critically appraised, and Grades of Recommendation Assessment, Development and Evaluation methods were used to determine the overall quality of evidence for primary outcomes. Previous systematic reviews on this topic were collated and evaluated using the Assessment of Multiple Systematic Reviews scoring system.
RESULTS
The search yielded 723 citations, 13 of which satisfied inclusion criteria. Among these, 6 were primary research articles and 7 were previous systematic reviews. Based on the included research articles, there was moderate evidence that the 24-hour NASCIS II (National Acute Spinal Cord Injury Studies) MPSS regimen has no impact on long-term neurological recovery when all postinjury time points are considered. However, there is also moderate evidence that subjects receiving the same MPSS regimen within 8 hours of injury achieve an additional 3.2 points (95% confidence interval = 0.10 to 6.33; = .04) of motor recovery compared with patients receiving placebo or no treatment.
CONCLUSION
Although safe to administer, a 24-hour NASCIS II MPSS regimen, when all postinjury time points are considered, has no impact on indices of long-term neurological recovery. When commenced within 8 hours of injury, however, a high-dose 24-hour regimen of MPSS confers a small positive benefit on long-term motor recovery and should be considered a treatment option for patients with SCI.

Meta-Analysis Review
PURPOSE
Ureteral stents are commonly used for the treatment of ureteral obstruction, most often urolithiasis. Their use may be associated with significant bothersome symptoms and discomfort. Prior studies have examined the effects of various medication regimens on ureteral stent symptoms. This study utilized Bayesian network meta-analysis to analyze all available evidence on the pharmacological management of ureteral stent-related symptoms.
MATERIALS AND METHODS
In December 2022 a systematic review was conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines on randomized prospective studies on pharmacological management of ureteral stent-related symptoms reporting outcomes using the Ureteral Stent Symptom Questionnaire score on urinary symptoms and pain. The data were analyzed in Review Manager 5.3 and R Studio where a Bayesian network meta-analysis was performed. Treatments were ranked using surface under the cumulative ranking curve and mean difference vs placebo with 95% credible intervals.
RESULTS
A total of 26 studies were analyzed. These were used to build networks which were modeled to run 100,000 Markov Chain Montecarlo simulations each. Drug-class analysis revealed the most effective class for each domain: for urinary symptoms, sexual performance, general health, and work performance-combined α-blocker and anticholinergic and phosphodiesterase 5 inhibitors; for pain-combined anticholinergic and pregabalin. The following were the most effective drugs and dosages for specific symptoms: for urinary symptoms-combined silodosin 8 mg+solifenacin 10 mg; for pain-combined silodosin 8 mg+solifenacin 10 mg; for sexual performance-tadalafil 5 mg. Combined silodosin 8 mg+solifenacin 10 mg+tadalafil 5 mg has the best general health scores while solifenacin 10 mg had the best work experience scores.
CONCLUSIONS
This network meta-analysis demonstrated that the most effective drug therapy is different for each symptom domain. It is important to consider a patient's chief complaint and domains in order to ascertain the optimal medication regimen for each patient. Further iterations of this analysis can be strengthened by trials that directly compare more of these drugs instead of relying on indirect evidence.

Review
INTRODUCTION
Seborrhoeic dermatitis affects at least 10% of the population. Malassezia (Pityrosporum) ovale is thought to be the causative organism, and causes inflammation by still poorly defined mechanisms. Seborrhoeic dermatitis tends to relapse after treatment.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of topical treatments for seborrhoeic dermatitis of the scalp in adults? What are the effects of topical treatments for seborrhoeic dermatitis of the face and body in adults? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 12 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: bifonazole, emollients, ketoconazole, lithium succinate, selenium sulphide, tar shampoo, terbinafine, and topical corticosteroids (betamethasone valerate, clobetasol propionate, clobetasone butyrate, hydrocortisone, mometasone furoate).

Meta-Analysis Review
OBJECTIVE
The outcomes of patients with metastatic phaeochromocytoma (PHEO) and paraganglioma (PGL) are unclear. We performed a systematic review and meta-analysis of baseline characteristics and mortality rates of patients with metastatic PHEO and PGL (PPGL).
DESIGN
Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, Scopus, Web of Science, and references of key articles were searched from inception to 2016.
PATIENTS
Studies comprised ≥20 patients with metastatic PPGL and reported baseline characteristics and follow-up data.
MEASUREMENTS
Reviewers extracted standardized data and assessed risk of bias using a modified Newcastle-Ottawa tool. Random-effects meta-analysis was used to pool event rates across studies.
RESULTS
Twenty retrospective noncomparative studies reported on 1338 patients with metastatic PHEO (685/1296, 52.9%) and PGL (611/1296, 47.1%), diagnosed at a mean age of 43.9 ± 5.2 years. Mean follow-up was 6.3 ± 3.2 years. Of 532 patients with reported data, 40.4% had synchronous metastases. Five-year (7 studies, n = 738) and 10-year (2 studies, n = 55) mortality rates for patients with metastatic PPGL were 37% (95% CI, 24%-51%) and 29% (95% CI, 17%-42%), respectively. Higher mortality was associated with male sex (RR 1.50; 95% CI, 1.11-2.02) and synchronous metastases (RR 2.43; 95% CI, 1.01-5.85).
CONCLUSIONS
Available low-quality evidence from heterogeneous studies suggests low mortality rates of patients with metastatic PPGL. Male sex and synchronous metastases correlated with increased mortality. The outcomes of patients with metastatic PPGL have been inadequately assessed, indicating the need for carefully planned prospective studies.

Review
INTRODUCTION
Seborrhoeic dermatitis affects at least 1-3% of the population. Malassezia (Pityrosporum) ovale is thought to be the causative organism, and causes inflammation involving T cells and complement. Seborrhoeic dermatitis tends to relapse after treatment.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of topical treatments for seborrhoeic dermatitis of the scalp in adults? What are the effects of topical treatments for seborrhoeic dermatitis of the face and body in adults? We searched: Medline, Embase, The Cochrane Library and other important databases up to February 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found nine systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: bifonazole, emollients, ketoconazole, lithium succinate, selenium sulphide, tar shampoo, terbinafine, and topical steroids (betamethasone valerate, clobetasol propionate, clobetasone butyrate, hydrocortisone, mometasone furate).

Meta-Analysis Review
OBJECTIVE
To evaluate systematically the clinical efficacy and safety of potassium dehydroandrographolide succinate injection (PDS) in treatment of infantile pneumonia.
METHODS
Randomized controlled trials (RCTs) of infantile pneumonia treated by PDS were searched in China National Knowledge Infrastructure Database, China Science and Technology Journal Database, Wanfang Database, Chinese Biomedical Literature Database, PubMed, and Cochrane Library, from January 1979 to July 2013. Two reviewers independently retrieved the RCTs and extracted the information. The quality of included studies was assessed by the Cochrane risk of bias, and a Meta-analysis was conducted with Review Manager 5.2 software.
RESULTS
A total of 9 studies with 1056 participants were included. The quality of the studies was generally no high, only one study mentioned the random method. The Meta-analysis indicated that PDS was significantly superior to the conventional therapy in the total effective rate [relative risk (RR) = 1.21, 95% CI (1.14, 1.27), P < 0.000 01], the time of temperature recovery [mean difference (MD) = -1.43, 95% CI (-1.75, -1.11), P < 0.000 01], rale disappeared and cough relieving [MD = -1.44, 95% CI (-1.93, -0.90), P < 0.000 01]. Six adverse drug reactions from five studies mainly represented rash and diarrhea, and no serious ADRs were reported.
CONCLUSION
Based on this systematic review, PDS was proved effective and relatively safe in treatment of infantile pneumonia. However the articles enrolled in the study were not high in quality, studies with higher quality should be conducted for assessment of efficacy and safety of PDS in treatment of infantile pneumonia.

Meta-Analysis Review
OBJECTIVE
To systematically evaluate the clinical efficacy and safety of Potassium Dehydroandrographolide Succinate Injection (PDSI) in the treatment of child epidemic parotitis (EP).
METHODS
Randomized controlled trials (RCTs) regarding PDSI in the treatment of child EP were searched in China National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Literature Database, PubMed, and Cochrane Library from inception to July 30, 2013. Two reviewers independently retrieved RCTs and extracted information. The Cochrane risk of bias method was used to assess the quality of included studies, and a meta-analysis was conducted with RevMan 5.2 software.
RESULTS
A total of 11 studies with 818 participants were included. The quality of the studies was generally low, among which only one study mentioned the random method. The meta-analysis indicated that PDSI was more effective than the conventional therapy with Western medicine for EP in the outcomes of the total effective rate [relative risk (RR)=1.23, 95% confidence interval (CI) [1.14, 1.33], P<0.01], the time of temperature return to normal, the time of detumescence [mean difference (MD)=-2.10, 95% CI [-2.78,-1.41], P<0.01], and the incidence of complications (RR=0.14, 95% CI [0.03, 0.72], P=0.02). There were 6 adverse drug reactions (ADRs) in this systematic review, 2 of which were mainly represented rash and diarrhea in the experiment group, while another 4 ADRs occurred in the control group.
CONCLUSIONS
Based on the systematic review, PDSI was effectiveness and relatively safety in the treatment of child EP. But further rigorously designed trials are warranted to determine its effectiveness.

Meta-Analysis Review
This study aims to evaluate the efficacy and safety of solifenacin for treating overactive bladder. Randomized controlled trials (RCTs) were identified and extracted from MEDLINE, Embase, and CENTRAL. The quality of the included RCTs was assessed using the Jadad score, and heterogeneity was analyzed using the chi-squared test. The data of the included RCTs were collected, extracted, and assessed by our protocol. A total of nine RCTs were identified from the search strategy. Compared with the placebo and tolterodine treatments, both short-term (mostly 12-week) trials indicated that solifenacin significantly reduced urgency episodes, micturitions, and incontinence episodes per 24 h. Compared with the solifenacin (5 mg) group, the solifenacin (10 mg) group was significantly better in terms of the number of micturitions per 24 h. With regard to adverse effects, the patients treated with solifenacin had significantly higher rates of constipation and blurred vision than patients treated with tolterodine. The solifenacin therapy was not inferior to tolterodine in terms of efficacy profiles and had a similar incidence of overall adverse events compared with tolterodine treatment. Solifenacin (5 mg) is thus a recommended dose because of its reported balance between efficacy and acceptable tolerability.

Meta-Analysis
BACKGROUND
Solifenacin is an anticholinergic that is used to treat overactive bladder syndrome (OAB) in children. It is important to ascertain the safety and tolerability of solifenacin in the paediatric population as solifenacin offers an alternative, is more bladder specific, and should have less anticholinergic side effects than other therapies.
OBJECTIVE
The aim of this study is to systematically evaluate the safety and tolerability of solifenacin in children and adolescents with OAB.
STUDY DESIGN
We included studies that reported the safety and tolerability of solifenacin in children and adolescents. All study types were included. Electronic searches were conducted in Ovid MEDLINE, Ovid Embase, TRIP, CINAHL and ICTRP on the 18th of January 2022. Risk of bias was assessed with the Cochrane Risk of Bias tool 2.0 (ROB-2) for randomised controlled trials (RCTs) and the Newcastle-Ottowa scale for cohort studies.
RESULTS
A total of twelve studies including two RCTs were included in this review. Results from the meta-analysis of RCTs showed the commonest side effects were constipation (RR 3.5, 95%CI 0.9-13.7) and dry mouth (RR 3.1 95%CI 0.2-53). In terms of tolerability, the effect estimate of ceasing solifenacin due to an adverse effect was 2.7 (95%CI 0.8-9.1). Within the cohort studies, out of the 779 patients 21.7% experienced side effects. The most common side effects were constipation (6.8%) and dry mouth/lips (6.0%) and 3.5% of patients ceased solifenacin due to adverse effects. Overall, the certainty of the evidence for side effects and tolerability were very low.
DISCUSSION
The reported incidence of side effects is low, and less than reported with oxybutynin use. However, the very low certainty of the evidence means the findings should be interpreted with caution. There is limited reporting of a prolonged QTc interval on ECG. Studies that described this only had an increase of QTc from baseline and not a clinically significant prolonged QTc that resulted in arrhythmias.
CONCLUSION
Solifenacin is an alternative anticholinergic for the treatment of OAB in children. However, given the paucity of good quality data on safety and tolerability it should be used cautiously in children with close monitoring for potential side effects.

Review
BACKGROUND
Constipation is an uncomfortable and common condition that affects many, irrespective of age. Since 1500 BC and before, health care practitioners have provided treatments and prevention strategies to patients for chronic constipation despite the significant variation in both medical and personal perceptions of the condition.
OBJECTIVE
To review relevant research evidence from clinical studies investigating the efficacy and safety of commercially available pharmacological laxatives in Canada, with emphasis on studies adopting the Rome criteria for defining functional constipation.
SEARCH METHODS
PubMed, Medline, Embase and Evidence-Based Medicine Reviews databases were searched for blinded or randomized clinical trials and meta-analyses assessing the efficacy of nonstimulant and stimulant laxatives for the treatment of functional constipation.
RESULTS
A total of 19 clinical studies and four meta-analyses were retrieved and abstracted regarding study design, participants, interventions and outcomes. The majority of studies focused on polyethylene glycol compared with placebo. Both nonstimulant and stimulant laxatives provided better relief of constipation symptoms than placebo according to both objective and subjective measures. Only one study compared the efficacy of a nonstimulant versus a stimulant laxative, while only two reported changes in quality of life. All studies reported minor side effects due to laxative use, regardless of treatment duration, which ranged from one week to one year. Laxatives were well tolerated by both adults and children.
