Meta-Analysis
OBJECTIVES
Pyomyositis, an acute bacterial infection of skeletal muscle usually resulting in abscess formation, is well recognised in tropical regions where it can account for up to 4% of adult surgical admissions. It is increasingly being reported from high-income temperate countries. Pyomyositis occurs across all ages and in both sexes. Mortality ranges from 1% to 23%. Many risk factors have been suggested. We aimed to identify factors associated with pyomyositis.
METHODS
We undertook a systematic review and meta-analysis, using PubMed, EMBASE, Scopus and the Cochran Library and hand-searching published papers. The random-effects model meta-analysis was used to calculate pooled estimated odd ratios with the corresponding 95% confidence interval.
RESULTS
All studies in the systematic review (n = 25) and the meta-analysis (n = 12) were hospital-based. Seven only included children. Relatively few studies have been published in the last decade, the majority of which are from high-income temperate settings. Staphylococcus aureus was the main organism isolated. Males under the age of 20 predominated, and mortality of up to 20% was reported. Factors associated with pyomyositis were HIV infection (OR = 4.82; 95% CI: 1.67-13.92) and fulfilling an AIDS surveillance definition (OR = 6.08; 95% CI: 2.79-13.23).
CONCLUSIONS
Our meta-analysis indicated significant associations between pyomyositis infection and HIV/AIDS. Major gaps in our understanding of the epidemiology, pathogenesis, clinical presentation, and outcome remain, highlighting the need for further research and more systematic studies. Pyomyositis merits consideration as a neglected tropical disease.

Meta-Analysis Review
BACKGROUND
The aim of this meta-analysis and systematic review was to evaluate the association between intraoperative bile cultures and postoperative complications of patients undergoing pancreaticoduodenectomy.
METHODS
A detailed literature search was performed from January 2015 to July 2022 in PubMed, Web of Science, Google Scholar, and EMBASE for related research publications. The data were extracted, screened, and graded independently. An analysis of pooled data was performed, and a risk ratio with corresponding confidence intervals was calculated and summarized.
RESULTS
A total of 8 articles were included with 1,778 pancreaticoduodenectomy patients who had an intraoperative bile culture performed. A systematic review demonstrated that some of the most common organisms isolated in a positive intraoperative bile culture were Enterococcus species, Klebsiella species, and E. coli. Four studies also showed that specific microorganisms were associated with specific postoperative complications (surgical site infection and intra-abdominal abscess). The postoperative complications that were evaluated for an association with a positive intraoperative bile culture were surgical site infections (risk ratio = 2.33, 95% confidence interval [1.47-3.69], P < .01), delayed gastric emptying (risk ratio = 1.23, 95% confidence interval [0.63-2.38], P = n.s.), 90-day mortality (risk ratio = 0.68, 95% confidence interval [0.01-52.76], P = n.s.), postoperative pancreatic hemorrhage (risk ratio = 1.70, 95% confidence interval [0.33-8.74], P = n.s.), intra-abdominal abscess (risk ratio = 1.70, 95% confidence interval [0.38-7.56], P = n.s.), and postoperative pancreatic fistula (risk ratio = 0.97, 95% confidence interval [0.72-1.32], P = n.s.).
CONCLUSION
The cumulative data suggest that a positive intraoperative bile culture has no association with predicting the postoperative complications of delayed gastric emptying, 90-day mortality, postoperative pancreatic hemorrhage, intra-abdominal abscess, or postoperative pancreatic fistula. However, the data also suggest that a positive intraoperative bile culture was associated with a patient developing a surgical site infection.

BACKGROUND AND OBJECTIVE
Topical and intralesional (IL) treatments may be considered the first-line therapy in patients with hidradenitis suppurativa (HS); however, the evidence supporting their use is limited. The aim of our review is to evaluate the efficacy and safety profile of topical and IL treatments in patients with HS.
MATERIALS AND METHODS
We designed a systematic review of the current medical literature available following the PICO(T) method. And including all types of studies (Study type [T]) of individuals with HS of any sex, age, and ethnicity (Population [P]) who received any topical or IL treatment for HS (Intervention [I]) compared to placebo, other treatments, or no treatment at all (Comparator [C]), and reported efficacy and/or safety outcomes (Outcomes [O]). Two outcomes were defined: quality of life and the no. of patients with, at least, one adverse event. The search was conducted in the Cochrane Library, MEDLINE, and Embase databases; study selection was performed based on pre-defined criteria. The risk of bias was determined in each study.
RESULTS
We obtained a total of 11,363 references, 31 of which met the inclusion criteria. These studies included 1143 patients with HS, 62% of whom were women. A total of 10, 8, 6, 2, and 5 studies, respectively, evaluated the use of photodynamic therapy (PDT), glucocorticoids, resorcinol, topical antibiotics, and other interventions. Most articles were case series (n=25), with only five randomized clinical trials (RCTs) and one cohort study. RCTs showed improvement in disease activity with topical clindamycin and botulinum toxin (BTX) vs placebo, and PDT with methylene blue (MB) niosomal vs free MB; however, intralesional triamcinolone acetonide was not superior to placebo. The risk of bias was low in three RCTs and high in two RCTs.
CONCLUSION
The quality of evidence supporting the use of topical, or IL treatments is low. However, it supports the use of topical clindamycin, PDT, and BTX. Well-designed RCTs with standardized outcomes and homogeneous populations of patients and lesions are needed to support decision-making in the routine clinical practice.

BACKGROUND
Periorbital and orbital cellulitis are infections of the tissue anterior and posterior to the orbital septum, respectively, and can be difficult to differentiate clinically. Periorbital cellulitis can also progress to become orbital cellulitis. Orbital cellulitis has a relatively high incidence in children and adults, and potentially serious consequences including vision loss, meningitis, and death. Complications occur in part due to inflammatory swelling from the infection creating a compartment syndrome within the bony orbit, leading to elevated ocular pressure and compression of vasculature and the optic nerve. Corticosteroids are used in other infections to reduce this inflammation and edema, but they can lead to immune suppression and worsening infection.
OBJECTIVES
To assess the effectiveness and safety of adjunctive corticosteroids for periorbital and orbital cellulitis, and to assess their effectiveness and safety in children and in adults separately.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2020, Issue 3); Ovid MEDLINE; Embase.com; PubMed; Latin American and Caribbean Health Sciences Literature Database (LILACS); ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We did not use any date or language restrictions in the electronic search for trials. We last searched the electronic databases on 2 March 2020.
SELECTION CRITERIA
We included studies of participants diagnosed with periorbital or orbital cellulitis. We excluded studies that focused exclusively on participants who were undergoing elective endoscopic surgery, including management of infections postsurgery as well as studies conducted solely on trauma patients. Randomized and quasi-randomized controlled trials were eligible for inclusion. Any study that administered corticosteroids was eligible regardless of type of steroid, route of administration, length of therapy, or timing of treatment. Comparators could include placebo, another corticosteroid, no treatment control, or another intervention.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures recommended by Cochrane.
MAIN RESULTS
The search yielded 7998 records, of which 13 were selected for full-text screening. We identified one trial for inclusion. No other eligible ongoing or completed trials were identified. The included study compared the use of corticosteroids in addition to antibiotics to the use of antibiotics alone for the treatment of orbital cellulitis. The study included a total of 21 participants aged 10 years and older, of which 14 participants were randomized to corticosteroids and antibiotics and 7 participants to antibiotics alone. Participants randomized to corticosteroids and antibiotics received adjunctive corticosteroids after initial antibiotic response (mean 5.13 days), at an initial dose of 1.5 mg/kg for three days followed by 1 mg/kg for another three days before being tapered over a one- to two-week period. We assessed the included study as having an unclear risk of bias for allocation concealment, masking (blinding), selective outcome reporting, and other sources of bias. Risk of bias from sequence generation and incomplete outcome data were low. The certainty of evidence for all outcomes was very low, downgraded for risk of bias (-1) and imprecision (-2). Length of hospital stay was compared between the group receiving antibiotics alone compared to the group receiving antibiotics and corticosteroids (mean difference (MD) 4.30, 95% confidence interval (CI) -0.48 to 9.08; 21 participants). There was no observed difference in duration of antibiotics between treatment groups (MD 3.00, 95% CI -0.48 to 6.48; 21 participants). Likewise, preservation of visual acuity at 12 weeks of follow-up between group was also assessed (RR 1.00, 95% CI 0.82 to 1.22; 21 participants). Pain scores were compared between groups on day 3 (MD -0.20, 95% CI -1.02 to 0.62; 22 eyes) along with the need for surgical intervention (RR 1.00, 95% CI 0.11 to 9.23; 21 participants). Exposure keratopathy was reported in five participants who received corticosteroids and antibiotics and three participants who received antibiotic alone (RR 1.20, 95% CI 0.40 to 3.63; 21 participants). No major complications of orbital cellulitis were seen in either the intervention or the control group. No side effects of corticosteroids were reported, although it is unclear which side effects were assessed.
AUTHORS' CONCLUSIONS
There is insufficient evidence to draw conclusions about the use of corticosteroids in the treatment of periorbital and orbital cellulitis. Since there is significant variation in how corticosteroids are used in clinical practice, additional high-quality evidence from randomized controlled trials is needed to inform decision making. Future studies should explore the effects of corticosteroids in children and adults separately, and evaluate different dosing and timing of corticosteroid therapy.

Review
To assess all published studies which describe what happens to the delivery of pressure ulcer/injury (PI/PU) care pathways as a result of detecting raised sub-epidermal moisture (SEM) delta (∆ ≥ 0.6). We undertook a systematic review of the literature, and included original research studies using either a prospective or retrospective study design that report the impact that assessment using SEM assessments have on healthcare practitioners' delivery of PI/PU care pathways in adults at risk of developing PI/PUs. The review protocol was registered on PROSPERO (CRD42023416975). A literature search was conducted in May 2023, using PubMed, CINAHL, Scopus, Cochrane, EMBASE, Web of Science and Science Direct databases. Data were extracted using a data extraction tool including elements such as country, setting, sample size, intervention, control and quality appraisal was undertaken using the Evidence-based Librarianship. We identified nine papers published between 2017 and 2022. The majority of these studies were conducted in England (n = 6; 67%). The systematic review included studies conducted across multiple care settings including acute care, medical-surgical units, and palliative care, highlighting the importance of PI/PU prevention and management across diverse patient populations. The PI/PU care pathways implemented in the studies varied, but commonly included elements such as the application or increased use of pressure-redistributing mattresses/cushions, implementation of repositioning plans, management of incontinence and moisture, regular skin inspection, and assessment of patient mobility. Out of the nine studies identified, seven reported PI/PU incidence. A meta-analysis of seven studies (N = 18 451) demonstrated a statistically significant reduction in visual PI/PU development in favour of SEM-guided care pathways compared to usual care (the odds ratio = 0.36 [95% confidence interval: 0.24-0.53, p < 0.00001]). This systematic review provides evidence that implementing SEM assessments in patients at risk of developing PI/PUs prompts anatomy-specific clinical actions. The subsequent implementation of enhanced and targeted skin care interventions leads to consistent and sustained reductions in hospital-acquired PU incidence. The findings emphasise the importance of incorporating SEM assessments as part of comprehensive PI/PU prevention strategies in all care settings and patient populations. This systematic review is limited by the predominance of observational studies and variable study quality. Future research should focus on randomised trials in different care settings that monitor the efficacy of preventive interventions and their impact in reducing PI/PU incidence when implemented based on SEM assessments.

Review
Noma is a rapidly progressing periodontal disease with up to 90% mortality in developing countries. Poor, immunocompromised and severely malnourished children (2 to 6 years old) are mostly affected by Noma. Prevention and effective management of Noma is hindered by the lack of sufficient cohesive studies on the microbial etiology of the disease. Research efforts have not provided a comprehensive unified story of the disease. Bridging the gap between existing studies gives an insight on the disease pathogenesis. This current systematic review of etiological studies focuses on the key players of dysbiosis in Noma disease. This review was performed in accordance with the Preferred Reporting Items for Systemic review and Meta-Analyses (PRISMA) statement. Web of Science, MEDLINE PubMed, Cochrane Library, Scopus, and Science Direct were searched electronically for clinical trials which applied culture dependent or molecular techniques to identify oral microbiota from Noma patients. Trials which involved periodontal diseases except Noma were excluded. After screening 275 articles, 153 full-texts articles were assessed for eligibility of which eight full text articles were selected for data extraction and analysis. The results show that 308 samples from 169 Noma participants (6 months to 15 years old) have been used in clinical trials. There was some variance in the microbiome identified due to the use of 3 different types of samples (crevicular fluid, subgingival plaque, and swabbed pus) and the ambiguity of the stage or advancement of Noma in the studies. Other limitations of the studies included in this review were: the absence of age-matched controls in some studies; the constraints of colony morphology as a tool in distinguishing between virulent fusobacterium genus at the species level; the difficulty in culturing spirochaetes in the laboratory; the choice of primers in DNA amplification; and the selection of probe sets in gene sequencing. This systematic review highlights spirochaetes and P. intermedia as putative trigger organisms in Noma dysbiosis, shows that F. nucleatum promotes biofilms formation in late stages of the disease and suggests that future studies should be longitudinal, with high throughput genome sequencing techniques used with gingival plaque samples from early stages of Noma.

Review
Computed tomography (CT) diagnosis of empyema is challenging because current literature features multiple overlapping pleural findings. We aimed to identify informative findings for structured reporting. The screening according to inclusion criteria (P: Pleural empyema, I: CT C: culture/gram-stain/pathology/pus, O: Diagnostic accuracy measures), data extraction, and risk of bias assessment of studies published between 01-1980 and 10-2021 on Pubmed, Embase, and Web of Science (WOS) were performed independently by two reviewers. CT findings with pooled diagnostic odds ratios (DOR) with 95% confidence intervals, not including 1, were considered as informative. Summary estimates of diagnostic accuracy for CT findings were calculated by using a bivariate random-effects model and heterogeneity sources were evaluated. Ten studies with a total of 252 patients with and 846 without empyema were included. From 119 overlapping descriptors, five informative CT findings were identified: Pleural enhancement, thickening, loculation, fat thickening, and fat stranding with an AUC of 0.80 (hierarchical summary receiver operating characteristic, HSROC). Potential sources of heterogeneity were different thresholds, empyema prevalence, and study year.

Meta-Analysis Review
Hidradenitis suppurativa (HS) is a chronic, recurrent and debilitating inflammatory skin disease of the hair follicle that usually presents as painful, deep-seated inflamed lesions in the apocrine gland-bearing areas of the body. HS patients suffer from uncomfortable signs and symptoms, such as pain, pruritus, malodour and suppuration, which may impair patients' quality of life (QoL). Although HS patients frequently experience these signs and symptoms, they are only occasionally assessed by clinicians and, unexpectedly, the scientific evidence available is limited and heterogeneous. The aim of this study is to summarize the evidence regarding the impact of HS signs and symptoms on QoL to serve as a basis for future research and help clinicians to consider them in the daily care of HS patients. A systematic review and meta-analysis were conducted following PRISMA Guidelines. The following search algorithm was used: (hidradenitis or "acne inversa") and (pain or itch or odour or malodour or suppuration or oozing or drainage) and ("quality of life"). The literature search identified 836 references, 17 of them met the eligible criteria and were included for analysis, representing 4929 HS patients. Mean age of the participants was 36.28 years and there was a predominance of female sex among study participants. The BMI of the population was in the range of over-weight and about two out five patients were active smokers. Studies included patients with mild to moderate HS, with a mean disease duration of 13.69 years. The HS signs and symptoms assessed were pain, pruritus, malodour and suppuration. Overall, the higher intensity of a sign or symptom correlated with poorer general QoL or specific QoL dimensions including sexual distress, anxiety, depression and sleep. The most frequently employed tool to assess QoL was the Dermatology Life Quality Index (DLQI). DLQI was used in 52.9% of the studies (9/17) with a mean value of 10.70 (2.16 SD). The scores employed to assess signs and symptoms severity were subjective and varied between studies, being the numerical rating scale (NRS) for each of the most used symptoms. The mean NRS value for pain was 3.99 and the mean NRS for pruritus was 4.99. In conclusion, we have summarized, categorized and analyzed the scientific evidence regarding signs and symptoms in HS patients and their impairment in QoL. Their assessment should be thorough and included during routine evaluation of HS patients to motivate therapeutic modifications and increase patients' health.

Meta-Analysis
BACKGROUND
Adalimumab is used as a first-line biologic agent in the management of moderate-to-severe hidradenitis suppurativa (HS). The objective of the present study was to evaluate the efficacy and safety of adalimumab in patients with moderate-to-severe HS.
METHODS
We performed a systematic review and meta-analysis according to Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines. Pooled estimates, namely standardized mean difference (SMD) and relative risk (RR), were calculated using random-effect model with trial sequential analysis. Small study effects were examined using the Doi plot. Certainty of evidence (CoE) was assessed using "The Grading of Recommendations Assessment, Development, and Evaluation" approach, and number-needed-to-treat (NNT) was calculated.
RESULTS
Five randomized controlled trials, involving 1014 patients, were included. We performed subgroup analysis of adalimumab administered subcutaneously both weekly and every other week. Adalimumab administered weekly was associated with better clinical response achievement (RR 1.76, 95% confidence interval [95% CI] 1.35-2.29; trial sequential analysis TSA-adjusted CI 1.01-3.08; CoE: low; NNT = 5) and a significant improvement in modified Sartorius score (SMD = -0.45, 95% CI = -0.76 to -0.13; CoE: very low; NNT = 10) and dermatology life quality index (DLQI) (SMD -0.47, 95% CI -0.61 to -0.32; CoE: low; NNT = 10). Nevertheless, adalimumab administered every other week showed an improvement only in modified Sartorius score. The pooled RRs of adverse events in both groups revealed no statistical significance when compared with the placebo.
CONCLUSIONS
Adalimumab administered weekly resulted in not only better clinical responses than placebo but also significantly improved disease severity and quality of life of patients with moderate-to-severe HS. Our study provides supporting evidence to the current guidelines and aids decision-making in the application of adalimumab in HS management.

Dermatology (Basel, Switzerland) 2021Several studies report a high prevalence of inflammatory arthritis among hidradenitis suppurativa (HS) patients. (Meta-Analysis)
Meta-Analysis
BACKGROUND
Several studies report a high prevalence of inflammatory arthritis among hidradenitis suppurativa (HS) patients.
OBJECTIVES
To study the association between HS and inflammatory arthritis.
METHODS
The systematic review and meta-analysis were performed according to the PRISMA guidelines to identify the association between HS and inflammatory arthritis, spondyloarthritis, ankylosing spondylitis (AS), and rheumatoid arthritis (RA).
RESULTS
Seven studies were entered in the analysis, with 200,361 HS patients and 385,599 controls. Pooled analysis illustrated a significantly increased risk of inflammatory arthritis in HS patients compared to controls (odds ratio [OR] 3.44; 95% confidence interval [CI] 1.92-6.17). There was also a statistically significant association between HS and spondyloarthritis (OR 2.10; 95% CI 1.40-3.15), and between HS and AS (OR 1.89; 95% CI 1.14-3.12). Moreover, pooled analysis showed a statistically significant association between HS and RA (OR 1.96; 95% CI 1.28-2.98).
CONCLUSIONS
Our findings show that HS patients have a 3-fold increased risk of developing inflammatory arthritis. HS patients are specifically at a higher risk for spondyloarthritis, its subtype AS, and RA.
