Meta-Analysis
Since early May 2022, outbreaks of Monkeypox (Mpox) cases have emerged and become a global concern. Studies exploring the gastrointestinal symptoms and/or liver injury of Mpox are still very limited. This systematic review and meta-analysis is the first to summarize the gastrointestinal symptoms reported by Mpox patients. We searched for Mpox studies published until October 21, 2022, in MEDLINE, EMBASE, SCOPUS, and organization websites. Mpox studies were observational studies that reported at least one of either gastrointestinal symptoms and/or liver injury in Mpox patients. Meta-analysis was done to obtain the pooled prevalence of gastrointestinal symptoms in Mpox patients. Subgroup analyses were done based on the study location, age groups, and Mpox Clades. The quality of included studies was assessed using the NIH Quality Assessment Tool. Overall, 31 studies that reported gastrointestinal symptoms and/or liver injury in Mpox patients were included. The reported gastrointestinal symptoms were abdominal pain, anorexia, diarrhea, nausea, and vomiting. There is a lack of reporting for liver injury. The most prevalent gastrointestinal symptoms in Mpox patients were anorexia (47%; 95% confidence interval [CI] 41%-53%), followed by vomiting (12%; 95% CI 11%-13%), nausea (10%; 95% CI 9%-11%), abdominal pain (9%; 95% CI 8%-10%), and diarrhea (5%; 95% CI 4%-6%). Additionally, the prevalence of proctitis, rectal/anal pain, and rectal bleeding were 11% (95% CI 11%-12%), 25% (95% CI 24%-27%), and 12% (95% CI 11%-13%), respectively. Anorexia was the most frequently reported gastrointestinal symptom in Mpox patients, followed by vomiting, nausea, abdominal pain, and diarrhea. Proctitis is a novel presentation of Mpox in the 2022 outbreak.

Review
BACKGROUND
Benign perianal disease carries significant morbidity and financial burden on the healthcare system. Given that sitz baths are recommended as a treatment modality, we considered whether using a continuous stream of water, in the form of a bidet, offers a convenient and effective alternative. Bidet use is the predominant form of perianal hygiene in Asia, but its role in perianal disease is unknown.
PURPOSE
To critically analyze and systematically review the current evidence regarding the effect of habitual bidet use on symptoms of benign perianal disease. A database search was conducted on MEDLINE and Epub Ahead of Print, Embase, ClinicalTrials.gov, the Cochrane Library, and ProQuest Dissertations. All studies on bidet use in pruritus ani, hemorrhoids, or anal fissures were included. The studies were screened and critically analyzed by two independent reviewers in line with PRISMA guidelines.
RESULTS
Two prospective trials and 1 cross-sectional study found that habitual use of bidets had no impact on the odds of developing hemorrhoids or hemorrhoidal symptoms. One RCT concluded that using bidets was non-inferior to sitz bath for post-hemorrhoidectomy pain. Two prospective trials and 1 cross-sectional study determined that habitual bidet use may increase the odds of developing pruritus ani. Two case series found that habitual bidet use may cause perianal burns or anterior anal fissures. A meta-analysis was not performed because only a limited number of studies were available, and they were of variable quality.
CONCLUSION
The current evidence does not identify using bidets as a treatment modality for perianal disease, and further research is warranted to study this increasingly utilized technology.

Accident; Analysis and Prevention Jul 2020The purpose of this study is to summarize the evidence for the association between exposure to a motor vehicle collision (MVC) and future low back pain (LBP).
OBJECTIVE
The purpose of this study is to summarize the evidence for the association between exposure to a motor vehicle collision (MVC) and future low back pain (LBP).
LITERATURE SURVEY
Persistent low back pain (LBP) is a relatively common complaint after acute injury in a MVC, with a reported 1 year post-crash prevalence of at least 31 % of exposed individuals. Interpretation of this finding is challenging given the high incidence of LBP in the general population that is not exposed to a MVC. Risk studies with comparison control groups need to be examined in a systematic review.
METHODOLOGY
A systematic search of five electronic databases from 1998 to 2019 was performed. Eligible studies describing exposure to a MVC and risk of future non-specific LBP were critically appraised using the Quality in Prognosis Studies (QUIPS) instrument. The results were summarized using best-evidence synthesis principles, a random effects meta-analysis and testing for publication bias.
SYNTHESIS
The search strategy yielded 1136 articles, three of which were found to be at low to medium risk of bias after critical appraisal. All three studies reported a positive association between an acute injury in a MVC and future LBP. Pooled analysis of the results resulted in an unadjusted relative risk of future LBP in the MVC-exposed and injured population versus the non-exposed population of 2.7 (95 % CI [1.9, 3.8]), which equates to a 63 % attributable risk under the exposed.
CONCLUSIONS
There was a consistent positive association in the critically reviewed literature that investigated the risk of future LBP following an acute MVC-related injury. For the patient with chronic low back pain who was initially injured in a MVC, more often than not (63 % of the time) the condition was caused by the MVC. These findings are likely to be of interest to clinicians, insurers, patients, governments and the courts. Future studies from both general and clinical populations would help strengthen these results.

Meta-Analysis
BACKGROUND
A large proportion of patients with Hirschsprung disease experience persistent obstructive symptoms after corrective surgery. Persistent obstructive symptoms may result in faecal stasis that can develop into Hirschsprung-associated enterocolitis, a potential life-threatening condition. Important treatment to improve faecal passage is internal anal sphincter relaxation using botulinum toxin injections.
AIM
To give an overview of all empirical evidence on the effectiveness of botulinum toxin injections in patients with Hirschsprung disease.
METHODS
A systematic review and meta-analysis was done by searching PubMed, EMBASE and the Cochrane Library, using entry terms related to: (1) Hirschsprung disease; and (2) Botulinum toxin injections. 14 studies representing 278 patients met eligibility criteria. Data that were extracted were proportion of patients with improvement of obstructive symptoms or less enterocolitis after injection, proportion of patients with adverse effects and data on type botulinum toxin, mean dose, average age at first injection and patients with associated syndromes. Random-effects meta-analysis was used to aggregate effects and random-effects meta-regression was used to test for possible confounding factors.
RESULTS
Botulinum toxin injections are effective in treating obstructive symptoms in on average 66% of patients [event rate (ER) = 0.66, = 0.004, = 49.5, = 278 patients]. Type of botulinum toxin, average dose, average age at first injections and proportion of patients with associated syndromes were not predictive for this effect. Mean 7 duration of improvement after one botulinum toxin injections was 6.4 mo and patients needed on average 2.6 procedures. There was a significant higher response rate within one month after botulinum toxin injections compared to more than one month after Botulinum toxin injections (ER = 0.79, ER = 0.46, Q = 19.37, < 0.001). Botulinum toxin injections were not effective in treating enterocolitis (ER 0.58, = 0.65, = 71.0, = 52 patients). There were adverse effects in on average 17% of patients (ER = 0.17, < 0.001, = 52.1, = 187 patients), varying from temporary incontinence to mild anal pain.
CONCLUSION
Findings from this systematic review and meta-analysis indicate that botulinum toxin injections are effective in treating obstructive symptoms and that adverse effects were present, but mild and temporary.

Journal of Minimally Invasive Gynecology Nov 2022To assess bowel function in women with deep infiltrating endometriosis according to surgical approach (radical vs conservative). (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To assess bowel function in women with deep infiltrating endometriosis according to surgical approach (radical vs conservative).
DATA SOURCES
Five databases were searched from 1970 to September 2021 to retrieve studies comparing radical (colorectal segmental resection) and conservative (shaving or discoid excision) surgery for bowel function in women with deep infiltrating endometriosis.
METHODS OF STUDY SELECTION
No language restriction was applied. Two reviewers extracted and combined data from the included studies, applying a meta-analytic model with random effects in all calculations. Results are expressed in risk ratio (RR) with 95% confidence interval (CI). Assessment of risk of bias and quality of evidence was performed by the Newcastle-Ottawa and Grading of Recommendations, Assessment, Development and Evaluation, respectively.
TABULATION, INTEGRATION, AND RESULTS
We included 13 studies in our meta-analysis, and most of them were of nonrandomized design. Conservative surgery had fewer events of constipation and frequent bowel movements when compared with radical surgery (RR, 2.31; 95% CI, 1.21-4.43; I = 0%; 3 studies; RR, 2.80; 95% CI 1.17-6.75; I = 0%; 2 studies, respectively). Defecation pain, anal incontinence loss, minor and major lower anterior resection syndrome, and Clavien-Dindo complications grade I to IV showed no statistically significant difference between surgeries. Grading of Recommendations, Assessment, Development and Evaluation assessment was low to very low for all outcomes.
CONCLUSION
Conservative surgery (shaving or discoid excision) presented fewer events of constipation and frequent bowel movements than colorectal segmental resection. There was a very low quality of evidence to provide recommendations regarding bowel function.

PURPOSE
The purpose of this systematic review is to evaluate whether self-expandable implantable vs non-self-expandable injectable bulking agents (second-line therapies) are equal/superior in terms of effectiveness (severity, quality of life [QoL]) and safety (adverse events) for faecal incontinence (FI).
METHODS
A systematic review was conducted, and five databases were searched (Medline via Ovid, Embase, Cochrane Library, University of York Centre for Reviews and Dissemination, and International Network of Agencies for Health Technology database). In-/exclusion criteria were predefined according to the PICOS scheme. The Institute of Health Economics risk of bias (RoB) tool assessed studies' internal validity. According to the Grading of Recommendations, Assessment, Development and Evaluation approach, the strength of evidence for safety outcomes was rated. A qualitative synthesis of the evidence was used to analyse the data.
RESULTS
The evidence consists of eight prospective single-arm, before-after studies (166 patients) fulfilling the inclusion criteria for assessing clinical effectiveness and safety of implantable bulking agents. FI severity statistically significantly improved in five of seven studies rated by the Cleveland Clinic FI Score and in three of five studies measured by the Vaizey score. Statistically significant improved disease-related QoL was found in one of five studies measured by the FI QoL Score and in one of two studies rated by the American Medical Systems score. Procedure-related adverse events occurred in 16 of 166 patients (i.e., intraoperative complications, anal discomfort and pain). Device-related adverse events occurred in 48 of 166 patients, including prostheses' dislodgement and removed/extruded prostheses. Studies were judged with moderate/high RoB. The strength of evidence for safety was judged to be very low.
CONCLUSION
Implantable bulking agents might be an effective and safe minimally invasive option in FI treatment if conservative therapies fail. FI severity significantly improved, however, effects on QoL need to be explored in further studies. Due to the uncontrolled nature of the case series, comparative studies need to be awaited.

Group A Streptococcus has been associated with a perianal infection. We conducted a systematic review of the literature on childhood streptococcal perianitis in three databases: Excerpta Medica, National Library of Medicine, and Web of Science. The main purposes were to document the clinical features, the tendency to recur, the association with an asymptomatic streptococcal throat carriage, the accuracy of rapid streptococcal tests, and the mechanism possibly underlying the acquisition of this infection. More than 80% of cases are boys ≤7.0 years of age with defecation disorders, perianal pain, local itch, rectal bleeding, or fissure and a sharply demarcated perianal redness. Perianitis is associated with a streptococcal tonsillopharyngitis in about every fifth case. The time to diagnosis is ≥3 weeks in 65% of cases. Recurrences occur within 3½ months in about 20% of cases. An asymptomatic group A streptococcal throat carriage occurs in 63% of cases. As compared with perianal Streptococcus A culture, the rapid streptococcal tests have a positive predictive value of 80% and a negative predictive value of 96%. It is hypothesized that digital inoculation from nasopharynx to anus underlies perianitis. Many cases are likely caused directly by children, who are throat and nasal carriers of Streptococcus A. Some cases might occur in children, who have their bottoms wiped by caregivers with streptococcal tonsillopharyngitis or carriage of Streptococcus.Conclusion: Perianitis is an infection with a distinctive presentation and a rather long time to diagnosis. There is a need for a wider awareness of this condition among healthcare professionals. What is Known: • Group A Streptococcus may cause perianitis in childhood. • Systemic antimicrobials (penicillin V, amoxycillin, or cefuroxime) are superior to topical treatment. What is New: • The clinical presentation is distinctive (defecation disorders, perianal pain, local itch, rectal bleeding, or fissure and a sharply demarcated perianal redness). • The time to diagnosis is usually ≥3 weeks. Recurrences occur in about 20% of cases.

Attributions of fault are often associated with worse injury outcomes; however, the consistency and magnitude of these impacts is not known. This review examined the prognostic role of fault on health, mental health, pain and work outcomes after transport injury. A systematic search of five electronic databases (Medline, Embase, CINAHL, PsycINFO, Cochrane Library) yielded 16,324 records published between 2000 and January 2018. Eligibility criteria were: adult transport injury survivors; prospective design; multivariable analysis; fault-related factor analysed; pain, mental health, general health or work-related outcome. Citations (n = 10,558, excluding duplicates) and full text articles (n = 555) were screened manually (Reviewer 1), and using concurrent machine learning and text mining (Reviewer 2; using Abstrackr, WordStat and QDA miner). Data from 55 papers that met all inclusion criteria were extracted, papers were evaluated for risk of bias using the QUIPS tool, and overall level of evidence was assessed using the GRADE tool. There were six main fault-related factors classified as: fault or responsibility, fault-based compensation, lawyer involvement or litigation, blame or guilt, road user or position in vehicle, and impact direction. Overall there were inconsistent associations between fault and transport injury outcomes, and 60% of papers had high risk of bias. There was moderate evidence that fault-based compensation claims were associated with poorer health-related outcomes, and that lawyer involvement was associated with poorer work outcomes beyond 12 months post-injury. However, the evidence of negative associations between fault-based compensation claims and work-related outcomes was limited. Lawyer involvement and fault-based compensation claims were associated with adverse mental health outcomes six months post-injury, but not beyond 12 months. The most consistent associations between fault and negative outcomes were not for fault attributions, per se, but were related to fault-related procedures (e.g., lawyer engagement, fault-based compensation claims).

BACKGROUND
Sinusoidal obstruction syndrome (SOS) is a kind of rare liver disease which is characterized by damage to small hepatic vessels, affecting particularly the sinusoidal endothelium. Due to the special etiology and high mortality, early diagnosis of SOS is significant for clinical survival and prognosis.
AIM
To generalize the common etiologies and clinical symptoms of SOS and summarize the characteristic magnetic resonance imaging (MRI) features so as to provide more valuable information for early diagnosis of SOS.
METHOD
We searched PubMed, Web of science, Wanfang Data, China Knowledge Resource Integrated, VIP, and Cochrane Library databases without a limiting period and the types of articles. The search process mainly revolved around the etiologies, common clinical symptoms, and MRI imaging features of SOS. Ultimately, 29 full articles were included in this review and 222 articles were excluded.
RESULTS
Eleven case reports included 13 patients. The etiologies of these patients including chemotherapy (5/13), medicinal herbs containing pyrrolidine alkaloids (PAs, . Tusanqi) (4/13), hematopoietic stem cell transplantation (HSCT) (2/13), drug toxicity (6-thioguanine) (1/13), and "poppers", a recreational drug used during anal intercourse (1/13). Eighteen case series including 497 patients, and SOS in 465 (93.6%) patients was caused by PAs. Ascites, abdominal pain and swelling, jaundice were the most common clinical symptoms. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT), total bilirubin (TBil), direct bilirubin (DBil), and prothrombin time (PT) had varying degrees of elevation. Heterogeneous signals on T1 weighted imaging/T2 weighted imaging (T1WI/T2WI), heterogeneous enhancement of liver parenchyma, ascites, hepatomegaly, narrowing and blurring of intrahepatic inferior vena cava and three main hepatic veins, edema around the portal vein, and gallbladder wall edema were the most common MRI imaging features of SOS.
CONCLUSION
In the West, SOS was mostly secondary to HSCT. Some SOS developed in the process of chemotherapy for hepatic metastatic tumor. A few SOS were caused by toxicity of certain drugs. In the East, Tusanqi was a major cause of SOS. Ascites, abdominal pain and swelling, jaundice were the common clinical symptoms. Elevations of ALT, AST, GGT, ALP, TBil, and DBil could be used as predictors of liver function damage. Numerous characteristic MRI imaging features could provide more valuable information for early diagnosis of SOS.

INTRODUCTION
Anal fissure is the most common cause of severe anorectal pain in adults, contributing significantly to coloproctology workloads. There are a wide variety of management options available, including topical nitrites, calcium channel blockers, botulinum toxin injection and sphincterotomy. The aim of this study was to review current options for the treatment of chronic anal fissure.
METHODS
A comprehensive search identifying randomized controlled trials comparing treatment options for anal fissure published between January 2000 and February 2020 was performed. The primary outcome assessed was healing at 8 weeks post commencing treatment. Secondary outcomes included recurrence, intolerance of treatment and complications.
RESULTS
A total of 2822 studies were identified. After removal of duplicates and non-relevant studies, we identified nine randomized controlled trials which met pre-defined criteria. There was a total of 775 patients. At 8 weeks, healing rates were 95.13% in those treated with sphincterotomy, 66.7% in the botulinum toxin group, 63.8% in the nitrate group, 52.3% for topical diltiazem and 50% for topical minoxidil. Recurrence was highest amongst those treated with botulinum toxin injection (41.7%) and lowest for sphincterotomy (6.9%). Although the absolute number is low, there was a risk of permanent incontinence with sphincterotomy.
CONCLUSION
This review of the randomized control data demonstrates that healing was significantly higher amongst those treated with sphincterotomy versus more conservative modalities. Topical nitrites had similar outcomes to botulinum toxin injection but were poorly tolerated in comparison to other treatments. The benefit of sphincterotomy was at a cost of increased complications, notably permanent incontinence.
