Review
BACKGROUND
Endobronchial ultrasound (EBUS) was introduced in the last decade, enabling real-time guidance of transbronchial needle aspiration (TBNA) of mediastinal and hilar structures and parabronchial lung masses. The many publications produced about EBUS-TBNA have led to a better understanding of the performance characteristics of this procedure. The goal of this document was to examine the current literature on the technical aspects of EBUS-TBNA as they relate to patient, technology, and proceduralist factors to provide evidence-based and expert guidance to clinicians.
METHODS
Rigorous methodology has been applied to provide a trustworthy evidence-based guideline and expert panel report. A group of approved panelists developed key clinical questions by using the PICO (population, intervention, comparator, and outcome) format that addressed specific topics on the technical aspects of EBUS-TBNA. MEDLINE (via PubMed) and the Cochrane Library were systematically searched for relevant literature, which was supplemented by manual searches. References were screened for inclusion, and well-recognized document evaluation tools were used to assess the quality of included studies, to extract meaningful data, and to grade the level of evidence to support each recommendation or suggestion.
RESULTS
Our systematic review and critical analysis of the literature on 15 PICO questions related to the technical aspects of EBUS-TBNA resulted in 12 statements: 7 evidence-based graded recommendations and 5 ungraded consensus-based statements. Three questions did not have sufficient evidence to generate a statement.
CONCLUSIONS
Evidence on the technical aspects of EBUS-TBNA varies in strength but is satisfactory in certain areas to guide clinicians on the best conditions to perform EBUS-guided tissue sampling. Additional research is needed to enhance our knowledge regarding the optimal performance of this effective procedure.

BACKGROUND
Neither dupilumab-associated facial erythema nor neck erythema was reported in phase 3 clinical trials for the treatment of atopic dermatitis, but there have been a number of reports of patients developing this adverse event in clinical practice.
OBJECTIVE
To outline all cases of reported dupilumab-associated facial or neck erythema to better characterize this adverse event, and identify potential etiologies and management strategies.
METHODS
A search was conducted on EMBASE and PubMed databases. Two independent reviewers identified relevant studies for inclusion and performed data extraction.
RESULTS
A total of 101 patients from 16 studies were reported to have dupilumab-associated facial or neck erythema. A total of 52 of 101 patients (52%) had baseline atopic dermatitis facial or neck involvement and 45 of 101 (45%) reported different cutaneous symptoms from preexisting atopic dermatitis, possibly suggesting a different etiology. Suggested etiologies included rosacea, allergic contact dermatitis, and head and neck dermatitis. Most commonly used treatments included topical corticosteroids, topical calcineurin inhibitors, and antifungal agents. In the 57 patients with data on the course of the adverse events, improvement was observed in 29, clearance in 4, no response in 16, and worsening in 8. A total of 11 of 101 patients (11%) discontinued dupilumab owing to this adverse event.
LIMITATIONS
Limited diagnostic testing, nonstandardized data collection and reporting across studies, and reliance on retrospective case reports and case series.
CONCLUSION
Some patients receiving dupilumab develop facial or neck erythema that differs from their usual atopic dermatitis symptoms. Prompt identification and empiric treatment may minimize distress and potential discontinuation of dupilumab owing to this adverse event.

Gel nail polish (GNP) has recently gained worldwide popularity. We have conducted a comprehensive summary of the complications of GNP through a literature search using the PubMed, Scopus, and Google Scholar databases to identify eligible contributions. Complications were divided into mechanical and traumatic nail disorders, allergic contact dermatitis (ACD), and ultraviolet (UV)-induced lesions. A total of 12 contributions were included, identifying 88 patients, all of whom were women. Six of the reports described ACD (62 cases, 70.5%), 3 concerned mechanical nail damage (23 cases, 26.1%), and 3 reported UV-induced skin lesions (3 cases, 3.4%). ACD developed an average of 30 months after GNP initiation. The most frequent culprit allergens were 2-hydroxypropyl methacrylate and 2-hydroxyethyl methacrylate. Pterygium inversum unguis was the most frequent mechanical lesion (n = 17). Squamous cell carcinoma was reported in 3 cases. The delay between UV exposure and the diagnosis of squamous cell carcinoma ranged from 11 to 15 years. Scant literature and a lack of education among consumers and beauticians have led to the uncontrolled use of GNP. The principle of managing nail cosmetic problems is prevention through education. There is a need for understanding the processes involved and the associated complications to facilitate appropriate treatment and safe use.

Gadolinium-based contrast agents (GBCAs) are frequently used in magnetic resonance imaging (MRI) examinations to increase sensitivity in diagnoses. Recently, an increase in the description of hypersensitivity reactions to GBCAs has been detected. We performed research in PubMed, PubMed, SCOPUS, and EMBASE until September 2021, searching for studies regarding immediate and delayed hypersensitivity reactions to gadolinium-based contrast agents in which an allergy study was performed. The initial research identified 149 articles written in English. After excluding articles duplicated and articles that had irrelevant designs, 26 articles were included. Finally, 17 studies concerning immediate reactions, six studies concerning non-immediate reactions, and three concerning both that performed allergy evaluations were selected. In the review, we analyzed the characteristics of immediate and delayed reactions and the results of the allergy study and cross-reactivity. Skin tests seem to have acceptable accuracy, but drug provocation tests are still needed when skin tests are negative o to find alternative agents. Although cross-reactivity patterns are not well established, cross-reactivity seems to exist among macrocyclic agents. Notwithstanding, the number of patients analyzed is low and further studies are required. A management algorithm is suggested.

Review
Pericardial disease secondary to sarcoidosis is a rare clinical entity with no observational studies in previous research. Therefore, we evaluated reported cases of pericarditis because of sarcoidosis to further understand its diagnosis and management. We performed a systematic review of previous research until December 16, 2020 in MEDLINE, Embase, Scopus, Cochrane Central Register of Controlled Trials, and Web of Science. Case reports and case series demonstrating pericardial involvement in sarcoidosis were included. Fourteen reports with a total of 27 patients were identified. Dyspnea (82%) was the most common presentation, with the lungs being the primary site of sarcoidosis in most patients (77%). The most frequently encountered pericardial manifestations were pericardial effusion (89%), constrictive pericarditis and cardiac tamponade (48%). Management of these patients included use of corticosteroids (82%), colchicine (11%), and nonsteroidal anti-inflammatory agents (7%). Similar to the general population, the most common intervention in these patients was pericardiocentesis (59%), pericardial window (30%), and pericardiectomy (19%). Overall, the majority of this population (70%) achieved clinical improvement during median follow-up time of 8 months. In conclusion, the prevalence and incidence of sarcoid-induced pericarditial disease remain unclear. Clinical manifestations of pericardial involvement are variable, though many patients present with asymptomatic pericardial effusions. No consensus exists on the treatment of this special population, but corticosteroids and combination therapies are considered first-line therapies because of their efficacy in suppressing pericardial inflammation and underlying sarcoidosis. Patients with refractory cases of pericarditis may also benefit therapeutically from the addition of nonsteroidal anti-inflammatory agents, colchicine, and/or biologics.

Meta-Analysis Review
Nickel-containing alloys are widely used in orthodontic appliances, even though nickel is by far the most common contact allergen. However, the scientific evidence concerning allergic reactions to nickel in orthodontic patients has not been evaluated systematically. The objective of this study was to investigate whether the prevalence of nickel hypersensitivity is affected by orthodontic treatment. Unrestricted electronic and manual searches were performed until July 2013 for human clinical studies assessing orthodontic treatment and nickel hypersensitivity. Methodological limitations were evaluated with the Downs and Black tool. Crude and adjusted odds ratios (ORs) with their 95% confidence intervals (CIs) were calculated from random-effects meta-analyses, followed by subgroup and sensitivity analyses. Thirty studies were included in the review, and 24 datasets with 10 184 patients in the meta-analyses. Orthodontic treatment had no significant effect on nickel hypersensitivity (n = 11; crude OR 0.99; 95%CI: 0.78-1.25; p = 0.914). However, when confounding from factors such as sex and piercings was taken into account, orthodontic treatment was associated with a lower risk of hypersensitivity (n = 1; adjusted OR 0.60; 95%CI: 0.40-0.80; p < 0.001). This was even more pronounced when orthodontic treatment was performed prior to piercing (n = 7; crude OR 0.35; 95%CI: 0.24-0.50; p < 0.001). Orthodontic treatment seems to have a protective role against nickel hypersensitivity, especially when it precedes piercings.

Review
Recurrence of DRESS syndrome is poorly characterized, and dermatologists must be prepared to predict, identify, and manage patients after treatment of the initial presentation. In this study, a primary literature search was conducted using PubMed, capturing all articles recording cases of DRESS syndrome recurrence. Forty-two articles were included for review comprising a total of 60 patients. The average age of patients was 46.3 years and time to recurrence was 123 days. Recurrent episodes presented more frequently with a higher fever and eosinophil absolute peak. Relapse was most often attributed to the introduction of a new medication (n = 18). Of the 17 cases in which outcome data were available, the survival rate of those experiencing recurrence was 71%. Viral reactivation with HHV-6 and organ involvement of the liver were frequently recorded complications. In essence, viral reactivation, severe internal organ involvement, and hematological abnormalities all portended a poorer prognosis in those experiencing DRESS syndrome recurrence. An adequate course of treatment should be maintained until clinical and laboratory parameters normalize, with a slow taper to minimize the likelihood of relapse in those most at risk.

Review
Food allergy is relatively common in both children and adults, and its prevalence is increasing. Early exposure of food allergens onto skin with an impaired epidermal barrier predisposes to sensitization and prevents the development of oral tolerance. While immediate-type food allergies are well described, less is known about delayed-type food allergies manifesting as dermatitis. This is due, in part, to limitations with current diagnostic testing for delayed-type food allergy, including atopy patch testing. We conducted a systematic review of food avoidance diets in delayed-type food allergies manifesting as dermatitis. While beneficial in some clinical circumstances, avoidance diets should be used with caution in infants and children, as growth impairment and developmental delay may result. Ultimately, dermatitis is highly multifactorial and avoidance diets may not improve symptoms of delayed-type food allergy until combined with other targeted therapies, including restoring balance in the skin microbiome and re-establishing proper skin barrier function.

Meta-Analysis Review
BACKGROUND
An increased cancer risk in patients with sarcoidosis has been suggested, although results are conflicting in a number of case-control and cohort studies. We conducted a systematic review of all available data and performed a meta-analysis to better define and quantify the association between sarcoidosis and cancer.
METHODS
We searched Medline and Embase for all original articles on cancer and sarcoidosis published up to January 2013. Two independent authors reviewed all titles/abstracts to identify studies according to predefined selection criteria. We derived summary estimates using a random-effects model and reported them as relative risk (RR). Publication bias was evaluated using a funnel plot and was quantified by the Egger test.
RESULTS
Sixteen original studies, involving > 25,000 patients, were included in the present review. The summary RR to develop all invasive cancers was 1.19 (95% CI, 1.07-1.32). The results for selected cancer sites indicated a significantly increased risk of skin (RR, 2.00; 95% CI, 1.69-2.36), hematopoietic (RR, 1.92; 95% CI, 1.41-2.62), upper digestive tract (RR, 1.73; 95% CI, 1.07-2.79), kidney (RR, 1.55; 95% CI, 1.21-1.99), liver (RR, 1.79; 95% CI, 1.03-3.11), and colorectal cancers (RR, 1.33; 95% CI, 1.07-1.67). There was no evidence of publication bias for all cancers (P = .9), nor for any specific cancer site.
CONCLUSIONS
The present meta-analysis suggests a significant, though moderate, association between sarcoidosis and malignancy.

Review
Allergic contact dermatitis related to cosmetic use can result from allergens not routinely evaluated by standard patch test protocols. Propyl, octyl, and dodecyl gallates are commonly used antioxidant preservatives with reports of associated allergic contact dermatitis in the literature. The objectives of this review were to investigate the role of gallates in allergic contact dermatitis and to explore products containing these preservatives. A systematic review of the literature through April 2016 was performed to explore cases of reported gallate allergy. Food and cosmetic product databases were searched for products containing gallates. Seventy-four cases of gallate contact allergy have been reported. In addition, a variety of commercially available cosmetic products and foods contain gallate chemicals. Propyl gallate is the most commonly reported gallate contact allergen and often causes facial and/or hand dermatitis.
