Review
Instrumental musicians are a risk group for skin diseases. A systematic review was performed on Pubmed database and in the musical literature. Most publications on dermatoses in musicians are case reports. The exact prevalence of skin diseases in musicians is unknown but high rates have been reported. The most at-risk musicians are percussionists, string and wind instrumentalists. Repeated physical trauma is a frequent cause of skin conditions in musicians (callosities, fiddler's neck syndrome…). The allergens most often reported in musicians' allergic contact dermatitis are metals (nickel, dichromate), exotic woods and cane reed components, colophony and propolis. The key preventive measures are early management of the skin disease, specific tests and avoidance of the causative allergens, together with better adjustment of playing techniques to reduce trauma.

Meta-Analysis Review
INTRODUCTION
Soluble interleukin-2 receptor (sIL-2 R), a valuable diagnostic biomarker for sarcoidosis, has been reported with variable results. Based on the literatures currently accessible, a systematic review and meta-analysis of the diagnostic performance of serum sIL-2 R for sarcoidosis were performed.
METHODS
Relevant studies investigating sIL-2 R for sarcoidosis diagnosis in several databases were searched and data on sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were pooled by STATA 16.0 software. Overall test performance was assessed using summary receiver operating characteristic curves and the area under the curve (AUC). Potential publication bias was assessed by Deeks test.
RESULTS
We included eleven studies involving 1,424 subjects, with 1,099 cases of sarcoidosis and 325 of non-sarcoidosis. The pooled parameters of sIL-2 R in diagnosing sarcoidosis were summarized as follows: sensitivity, 0.85 (95% CI: 0.72-0.93); specificity, 0.88 (95% CI: 0.72-0.96); PLR, 7.3 (95% CI: 2.7-20.1); NLR, 0.17 (95% CI:0.08-0.36); DOR, 44 (95% CI: 8-231); and the AUC, 0.93 (95% CI: 0.90-0.95). No publication bias was identified ( = 0.64).
CONCLUSIONS
Evidence suggests sIL-2 R performs well in diagnosing sarcoidosis. Nevertheless, results of sIL-2 R assay should be interpreted with other diagnostic examinations.

Meta-Analysis Review
Evidence regarding the association between lifestyle factors and hand eczema is limited.To extensively investigate the association between lifestyle factors (smoking, alcohol consumption, stress, physical activity, body mass index, diet, and sleep) and the prevalence, incidence, subtype, severity, and prognosis of hand eczema, a systematic review and meta-analysis were conducted in accordance with the Meta-analysis Of Observational Studies in Epidemiology consensus statement. MEDLINE, Embase, and Web of Science were searched up to October 2021. The (modified) Newcastle-Ottawa Scale was used to judge risk of bias. Quality of the evidence was rated using the Grades of Recommendation, Assessment, Development and Evaluation approach. Eligibility and quality were blindly assessed by two independent investigators; disagreements were resolved by a third investigator. Data were pooled using a random-effects model, and when insufficient for a meta-analysis, evidence was narratively summarized. Fifty-five studies were included. The meta-analysis (17 studies) found very low quality evidence that smoking is associated with a higher prevalence of hand eczema (odds ratio 1.18, 95% confidence interval 1.09-1.26). No convincing evidence of associations for the other lifestyle factors with hand eczema were found, mostly due to heterogeneity, conflicting results, and/or the limited number of studies per outcome.

The Journal of Prosthetic Dentistry Dec 2022Type IV hypersensitivity reactions (Type IV HR) are immune responses mediated by antigen-specific effector T cells.
STATEMENT OF PROBLEM
Type IV hypersensitivity reactions (Type IV HR) are immune responses mediated by antigen-specific effector T cells.
PURPOSE
The purpose of this clinical report and systematic review was to report the clinicopathological features of Type IV HR in the oral mucosa and to present a systematic literature review of case reports and case series of individuals with Type IV HR in the oral mucosa related to contact with dental materials.
MATERIAL AND METHODS
The presented clinical lesions were melanotic macules with burning that affected the internal labial mucosa in contact with composite resin veneer crowns. Histopathological and immunohistochemical analysis of the lesion was performed. The systematic literature review was performed based on a search in 4 electronic databases (PubMed/MEDLINE, Scopus, Web of Science, and Ovid).
RESULTS
Immunohistochemistry showed positivity for CD4, CD8, CD20, CD3, tryptase, and CD117. After conservative treatment, the patient reported improvement of symptoms, and a decrease in the number of inflammatory cells was verified. Twenty-one articles were included in the review. Unlike the present patient, the authors of all the articles recommended radical treatment with the removal of the dental material.
CONCLUSIONS
Type IV HR in oral mucosa is rare, and the assessment of clinical and histopathological characteristics is essential to perform an accurate diagnosis and provide appropriate treatment.

Review
Mycoplasma pneumoniae induced rash and mucositis (MIRM) is a relatively newly identified clinical entity which is characterized by mucocutaneous manifestations in the setting of Mycoplasma infection. Though a clinically distinct disease, MIRM exists on a diagnostic continuum with entities including erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and the recently described reactive infectious mucocutaneous eruption (RIME). In this systematic review, we discuss published findings on the epidemiology, clinical manifestations, diagnosis, and management of MIRM, with an emphasis on ocular disease. Lastly, we discuss some of the most recent developments and challenges in characterizing MIRM with respect to the related diagnosis of RIME.

Meta-Analysis
Background There is no consensus regarding the relative prognostic value of cardiac MRI and fluorodeoxyglucose (FDG) PET in cardiac sarcoidosis. Purpose To perform a systematic review and meta-analysis of the prognostic value of cardiac MRI and FDG PET for major adverse cardiac events (MACE) in cardiac sarcoidosis. Materials and Methods In this systematic review, MEDLINE, Ovid Epub, CENTRAL, Embase, Emcare, and Scopus were searched from inception until January 2022. Studies that evaluated the prognostic value of cardiac MRI or FDG PET in adults with cardiac sarcoidosis were included. The primary outcome of MACE was assessed as a composite including death, ventricular arrhythmia, and heart failure hospitalization. Summary metrics were obtained using random-effects meta-analysis. Meta-regression was used to assess covariates. Risk of bias was assessed using the Quality in Prognostic Studies, or QUIPS, tool. Results Thirty-seven studies were included (3489 patients with mean follow-up of 3.1 years ± 1.5 [SD]); 29 studies evaluated MRI (2931 patients) and 17 evaluated FDG PET (1243 patients). Five studies directly compared MRI and PET in the same patients (276 patients). Left ventricular late gadolinium enhancement (LGE) at MRI and FDG uptake at PET were both predictive of MACE (odds ratio [OR], 8.0 [95% CI: 4.3, 15.0] [ < .001] and 2.1 [95% CI: 1.4, 3.2] [ < .001], respectively). At meta-regression, results varied by modality ( = .006). LGE (OR, 10.4 [95% CI: 3.5, 30.5]; < .001) was also predictive of MACE when restricted to studies with direct comparison, whereas FDG uptake (OR, 1.9 [95% CI: 0.82, 4.4]; = .13) was not. Right ventricular LGE and FDG uptake were also associated with MACE (OR, 13.1 [95% CI: 5.2, 33] [ < .001] and 4.1 [95% CI: 1.9, 8.9] [ < .001], respectively). Thirty-two studies were at risk for bias. Conclusion Left and right ventricular late gadolinium enhancement at cardiac MRI and fluorodeoxyglucose uptake at PET were predictive of major adverse cardiac events in cardiac sarcoidosis. Limitations include few studies with direct comparison and risk of bias. Systematic review registration no. CRD42021214776 (PROSPERO) © RSNA, 2023 .

Meta-Analysis Review
BACKGROUND
Endobronchial ultrasound (EBUS)-guided intranodal forceps biopsy (IFB) is considered complementary to EBUS-guided transbronchial needle aspiration (TBNA) (EBUS-TBNA) for patients with intrathoracic lymphadenopathy either when additional tissue is requested for comprehensive molecular testing or for suspected lymphoma and sarcoidosis. This systematic review and meta-analysis investigated the diagnostic yield and complications of combined EBUS-IFB and EBUS-TBNA compared with EBUS-TBNA alone.
METHODS
A systematic search was performed of Medline, Embase, and Google Scholar for studies evaluating the use of EBUS-IFB for diagnosis of intrathoracic adenopathy, and the quality of each study was assessed using the Quality Assessment, Data abstraction and Synthesis-2 tool. Using inverse variance weighting, a meta-analysis of diagnostic yield estimations was performed. The complications related to the procedure were also reviewed.
RESULTS
Six observational studies with 443 patients undergoing 467 biopsies were included in the final analysis. Meta-analysis yielded a pooled overall diagnostic yield of 67% (312 of 467) for EBUS-TBNA and 92% (428 of 467) for EBUS-TBNA in combination with EBUS-IFB, with an inverse variance-weighted odds ratio of 5.87 (95% confidence interval, 3081 to 9.04; P < .00001) and an I of 15%. The overall complications included pneumomediastinum (1%), bleeding (0.8%), and respiratory failure (0.6%). The funnel plot analysis illustrated no major publication bias. Subgroup analysis showed increased diagnostic yield for lymphoma (86% vs 30%; P = .03) and sarcoidosis (93% vs 58%; P < .00001).
CONCLUSIONS
The addition of EBUS-IFB to EBUS-TBNA improves the overall diagnostic yield of sampling intrathoracic adenopathy when compared with EBUS-TBNA alone. The complication rates of the combined approach are higher than with EBUS-TBNA, but they are reportedly lower than with transbronchial or surgical biopsies.

Meta-Analysis Review
Healthcare workers (HCWs) are considered a high-risk group for developing hand eczema (HE), mainly owing to wet work and contact with allergens at work. To meta-analyse the prevalence and incidence of HE in HCWs, as well as mapping the prevalence of atopic dermatitis (AD) and HE severity in HCWs. A systematic review and meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 guidelines. Published literature from 2000 to 2022 was eligible based on predefined inclusion and exclusion criteria. A total of 18 studies were included. Pooled life-time, 1-year and point prevalence of self-reported HE in HCWs was 33.4% (95% confidence interval [CI]: 28.3-38.6), 27.4% (95% CI: 19.3-36.5) and 13.5% (95% CI: 9.3-18.4), respectively. AD prevalence was 15.4% (95% CI: 11.3-19.9). Overall, the majority of HCWs reported mild HE. One included study assessed HE incidence reporting 34 cases/1000 person years. Most studies scored low-moderate using the New Ottawa Scale and the pooled point prevalence data showed broad CIs. In conclusion, the high prevalence of HE in HCWs underlines the increased risk and need for preventive measures for this professional group. There is, however, a need of further standardized high-quality studies.

Meta-Analysis Review
BACKGROUND
During the last few years, investigators have debated the role that infectious agents may have in sarcoidosis pathogenesis. With the emergence of new molecular biology techniques, several studies have been conducted; therefore, we performed a meta-analysis in order to better explain this possible association.
METHODS
This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement from the Cochrane collaboration guidelines. Four different databases (Medline, Scopus, Web of Science, and Cochrane Collaboration) were searched for all original articles published from 1980 to 2015. The present meta-analysis included case-control studies that reported the presence of microorganisms in samples of patients with sarcoidosis using culture methods or molecular biology techniques. We used a random effects or a fixed-effect model to calculate the odds ratio (OR) and 95% confidence intervals (CI). Sensitivity and subgroup analyses were performed in order to explore the heterogeneity among studies.
RESULTS
Fifty-eight studies qualified for the purpose of this analysis. The present meta-analysis, the first, to our knowledge, in evaluation of all infectious agents proposed to be associated with sarcoidosis and involving more than 6000 patients in several countries, suggests an etiological link between Propionibacterium acnes and sarcoidosis, with an OR of 18.80 (95% CI 12.62, 28.01). We also found a significant association between sarcoidosis and mycobacteria, with an OR of 6.8 (95% CI 3.73, 12.39). Borrelia (OR 4.82; 95% CI 0.98, 23.81), HHV-8 (OR 1.47; 95% CI 0.02, 110.06) as well as Rickettsia helvetica, Chlamydia pneumoniae, Epstein-barr virus and Retrovirus, although suggested by previous investigations, were not associated with sarcoidosis.
CONCLUSION
This meta-analysis suggests that some infectious agents can be associated with sarcoidosis. What seems clear is that more than one infectious agent might be implicated in the pathogenesis of sarcoidosis; probably the patient's geographical location might dictate which microorganisms are more involved. Future investigations and more clinical trials are need to bring these evidences to a more global level.

Despite the large number of performed studies, the etiology and pathogenesis of sarcoidosis still remain unknown. Most researchers allude to the possible autoimmune or immune-mediated genesis of the disease. This review attempts an integral analysis of currently available information suggesting an autoimmune genesis of sarcoidosis and is divided into four categories: the evaluation of clinical signs described both in patients with sarcoidosis and "classic" autoimmune diseases, the role of triggering factors in the development of sarcoidosis, the presence of immunogenic susceptibility in the development of the disease, and the analysis of cellular and humoral immune responses in sarcoidosis. Studying the etiology and pathogenesis of sarcoidosis will improve diagnostic procedures as well as the prognosis and patients' quality of life.
