BACKGROUND
Chronic spontaneous urticaria (CSU) is believed to be Autoimmune (aiCSU) (type IIb CSU) in at least 8% of patients, associated with mast cell-activating IgG autoantibodies. Basophil tests such as the basophil activation test (BAT) and basophil histamine release assay (BHRA) are considered the best single tests for an aiCSU diagnosis. To date, the strength of associations among a positive BAT and/or BHRA (BAT/BHRA) and CSU features, patient demographics, and response to treatment remains poorly characterized.
OBJECTIVE
To evaluate the strength of current evidence on basophil tests as parameters for CSU characteristics.
METHODS
We performed a systematic literature search and review to assess the relationship between BAT/BHRA and clinical and laboratory parameters of CSU. Of 1,058 records found in the search, 94 studies were reviewed by experts in urticaria and 42 were included in the analysis.
RESULTS
In CSU patients, BAT/BHRA showed a strong level of evidence for an association with high disease activity and low levels of total IgE. A weak level of evidence was shown for the association of BAT/BHRA and the presence of angioedema, and basopenia.
CONCLUSIONS
Our results suggest that aiCSU defined by BAT/BHRA is more active or severe and is linked to other aiCSU markers such as low total IgE/basopenia. Basophil tests should be standardized and implemented in routine clinical care to improve the diagnosis and treatment of patients with aiCSU.

Meta-Analysis
IMPORTANCE
Sulfamethoxazole (SMX) and cotrimoxazole (CTX), a fixed-dose combination of SMX and trimethoprim in a 5:1 ratio, are antibacterial sulfonamides commonly used for treating various diseases. A substantial prevalence of severe cutaneous adverse reactions (SCARs) following the administration of these drugs has been reported. However, the association between human leukocyte antigen (HLA) genotypes and SMX/CTX-induced SCARs has remained unclear.
OBJECTIVE
To investigate the association between HLA genotypes and SMX/CTX-induced SCARs.
DATA SOURCES
A comprehensive search was conducted in CENTRAL (Cochrane Library), MEDLINE, and Embase from inception to January 17, 2023.
STUDY SELECTION
Case-control studies that recruited patients who had experienced SCARs following SMX or CTX were included, and HLA alleles were analyzed.
DATA EXTRACTION AND SYNTHESIS
Two independent authors extracted data on study characteristics and outcome data. The Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines were followed. The Newcastle-Ottawa Scale for case-control studies was used to assess study quality. Odds ratios (ORs) were calculated using a random-effects model for meta-analysis.
MAIN OUTCOMES AND MEASURES
The prespecified outcome was the OR comparing SMX/CTX-induced SCARs with healthy or SMX/CTX-tolerant controls based on different HLA alleles.
RESULTS
Six studies involving 322 patients with SCAR were included, including 236 patients with Stevens-Johnson syndrome/toxic epidermal necrolysis, 86 with drug reaction with eosinophilia and systemic symptoms, 8448 healthy controls, and 229 tolerant controls. Significant associations were found in HLA-A*11:01 (OR, 2.10; 95% CI, 1.11-4.00), HLA-B*13:01 (OR, 5.96; 95% CI, 1.58-22.56), HLA-B*15:02 (OR, 2.23; 95% CI, 1.20-4.14), HLA-B*38:02 (OR, 3.47; 95% CI, 1.42-8.48), and HLA-C*08:01 (OR, 2.63; 95% CI, 1.07-6.44) compared with tolerant controls. In the Stevens-Johnson syndrome/toxic epidermal necrolysis subgroup, significant associations were found in HLA-B*15:02 (OR, 3.01; 95% CI, 1.56-5.80) and HLA-B*38:02 (OR, 5.13; 95% CI, 1.96-13.47). In the drug reaction with eosinophilia and systemic symptoms subgroup, significant associations were found in HLA-A*68:01 (OR, 12.86; 95% CI, 1.09-151.34), HLA-B*13:01 (OR, 23.09; 95% CI, 3.31-161.00), HLA-B*39:01 (OR, 4.56; 95% CI, 1.31-15.82).
CONCLUSIONS AND RELEVANCE
The results of this systematic review and meta-analysis suggest that multiple HLA alleles (HLA-A*11:01, HLA-B*13:01, HLA-B*15:02, HLA-B*38:02, and HLA-C*0801) are associated with SMX/CTX-induced SCARs.

Review
Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN), grouped together under the terminology of epidermal necrolysis (EN), are a spectrum of life-threatening dermatologic conditions. A lack of standardization and validation for existing endpoints has been identified as a key barrier to the comparison of these therapies and development of evidenced-based treatment. Following PRISMA guidelines, we conducted a systematic review of prospective studies involving systemic or topical treatments for EN, including dressing and ocular treatments. Outcomes were separated into mortality assessment, cutaneous outcomes, non-cutaneous clinical outcomes, and mucosal outcomes. The COSMIN Risk of Bias tool was used to assess the quality of studies on reliability and measurement error of outcome measurement instruments. Outcomes across studies assessing treatment in the acute phase of EN were varied. Most data came from prospective case reports and cohort studies representing the lack of available randomized clinical trial data available in EN. Our search did not reveal any EN-specific validated measures or scoring tools used to assess disease progression and outcomes. Less than half of included studies were considered "adequate" for COSMIN risk of bias in reliability and measurement error of outcome measurement instruments. With little consensus about management and treatment of EN, consistency and validation of measured outcomes is of the upmost importance for future studies to compare outcomes across treatments and identify the most effective means of combating the disease with the highest mortality managed by dermatologists.

BACKGROUND
Stevens-Johnson syndrome (SJS) is considered a hypersensitivity syndrome affecting the skin and mucous membranes. It has been reported that an anticonvulsant drug, oxcarbazepine, may cause Stevens-Johnson syndrome and toxic epidermal necrolysis (TEN). However, the clinical features of oxcarbazepine-induced Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) remain ambiguous. This article aims to explore the clinical features of SJS/TEN.
METHODS
Systematic searches of several Chinese and English databases were conducted for case reports published on PubMed, EMBASE, Web of Science, MEDLINE, CNKI from January 1, 2007 to March 1, 2023.
RESULTS
A total of seventeen patients (10 males and 7 females) were included in this study, including nine adult patients and eight pediatric patients. The results showed that males seem to have a higher prevalence of SJS/TEN than females, and SJS/TEN usually occurs within 2 weeks after administration of oxcarbazepine (OXC). The main clinical manifestations among the included patients were rashes or maculopapules (17 cases, 100%), fever (11 cases, 64.7%), mucosal lesions (15 cases, 88.2%), conjunctivitis with/without ocular discharge (12 cases, 70.6%), and blisters (12 cases, 70.6%). After stopping OXC or switching to other drugs that treat primary disease as well as treatment with IVIG, glucocorticoid, anti-allergy, and fluid replacement, eight of the included patients recovered completely, and another eight of the included patients reported symptomatic improvement, while the prognosis of one of the included patients was not reported.
CONCLUSION
Diverse clinical signs and symptoms of SJS/TEN might result in misinterpretation and delayed diagnosis. It should be identified and treated immediately to avoid significant consequences and potentially jeopardize patients' lives.

Meta-Analysis
BACKGROUND
We aimed to estimate the prevalence and incidence of syphilis at global, regional and national levels for human immunodeficiency virus (HIV)-positive and HIV-negative men who have sex with men (MSM) and explore the association between demographic and social behavioural factors and syphilis infection.
METHODS
We searched PubMed, Embase, and the Cochrane Library from 1 January 2012 to 31 December 2022 for studies of reported crude syphilis prevalence or incidence in MSM or with sufficient data to calculate prevalence or incidence rate in MSM.
RESULTS
We included 376 articles reporting on 409 records from 62 countries to calculate syphilis prevalence and incidence in MSM. The pooled prevalence of syphilis in MSM was 10.4%, with substantial differences between countries and regions. Syphilis prevalence was substantially higher in HIV-positive than in HIV-negative MSM. The pooled incidence of syphilis in MSM was 76.4 per 1000 person-years. Older age, lower education, nitrite or recreational drug use, group sex, and multiple sexual partners were identified as risk factors for syphilis infection.
CONCLUSIONS
A disproportionate geographic pattern of syphilis infection in MSM and significant threats of syphilis infection were revealed. The 'hidden risk' in specific regions and the inadequately elucidated drivers of high-risk behaviours, need to be fully acknowledged and addressed.

Review
Fixed drug eruption (FDE) is a cutaneous drug reaction characterised by recurrent skin lesions occurring at the same site after each exposure to a causative agent. There is currently limited evidence in the paediatric population. The objective of this systematic review is to investigate the clinical features, causative agents and management of paediatric FDE. A systematic search of the English and French literature on paediatric FDE was conducted using the Medline and Embase databases. After full-text article review, 92 articles were included, representing a total of 233 patients. Antibiotics were the most frequent triggering agents, mainly sulfonamides (65.0% of antibiotics). Systemic symptoms were rare, and most patients only received supportive therapy. One hundred and six patients (106) performed a test to confirm the causative agent. Of these, 72.6% had oral provocation tests (OPTs) and 28.3% had patch tests. The patient's age, presence of bullous lesions and mucosal lesions were similar between tested and untested patients. It did not seem to influence the decision to perform OPTs. Paediatric FDE is a non-severe skin drug reaction. Antibiotics were the most reported triggering agents. Drug testing, including oral provocation test, was safely performed in the paediatric population.

Review
PURPOSE OF REVIEW
The advances in the knowledge of the molecular basis of the inflammatory response in chronic rhinosinusitis with nasal polyps (CRSwNP) have led the management of these patients towards personalized and precision medicine. Surgery has been positioned as a suitable alternative in patients who do not achieve control with appropriate medical treatment, but polypoid recurrences remain a constraint. The emergence of new surgical approaches based on patient phenotyping and the poor disease control associated with type 2 inflammatory phenotype makes it necessary to review the role of personalized and precision surgery in managing the disease.
RECENT FINDINGS
Surgical approaches based on wide resection of bony sinus structures and the treatment of mucosa lining the sinonasal cavity have been analyzed and compared with other techniques and seem to offer more favorable surgical outcomes and improved quality of life (QoL), in addition to lower relapse rates. The innovations with new complementary surgical techniques, such as reboot surgery adding an extended autologous mucosal graft from the nasal floor (mucoplasty), may benefit endoscopic and QoL outcomes in the most severe CRSwNP patients with type 2 phenotype. Using bilateral endonasal mucoplasty as a complementary technique to reboot surgery is a suitable technical choice that has improved short- and medium-term QoL and endoscopic outcomes for patients with severe CRSwNP. These results are likely due to a combination of the extension of reboot and the inherent inflammatory and healing properties of mucoplasty. We propose this technique as a valuable surgical resource, although more robust clinical studies are needed to evaluate its long-term benefits comprehensively.

Meta-Analysis
BACKGROUND
The effectiveness and safety of pharmacological treatments for acute urticaria remain unclear.
OBJECTIVE
To systematically review and meta-analyze the efficacy and safety of pharmacological treatments for acute urticaria in emergency department (ED) and non-ED settings.
METHODS
We searched electronic databases and gray literature up to July 8, 2023, without language restrictions. Randomized clinical trials (RCTs) relating to pharmacological interventions in patients with acute urticaria, regardless of age, were eligible for inclusion. The relevant outcomes of interest were the treatment efficacy and safety profiles. The results are presented as standardized mean differences (SMDs) or odds ratios (ORs).
RESULTS
We identified 8 RCTs comprising 680 patients. Regarding the ED setting (2 trials, n = 118), intramuscular first-generation H1-antihistamine (fgAH) was more efficacious in decreasing pruritus symptoms (SMD, -0.38; 95% confidence interval [CI], -0.75 to -0.02) but had higher sedative effects than H2-blockers. With comparable pruritus symptom improvement (2 trials, n = 295), intravenous second-generation H1-antihistamine (sgAH) had favorable clinical outcomes compared with intravenous fgAH in the ED setting with a lower risk of return to any ED/clinic (OR, 0.31; 95% CI, 0.12-0.83) and lower risk of any adverse event (OR, 0.24; 95% CI, 0.09-0.63). The efficacy of adjunctive therapy with a short course of systemic glucocorticosteroids in ED and non-ED settings remains unclear. No serious concerns regarding the safety profiles were observed in any of the treatment comparisons.
CONCLUSIONS
H1-antihistamine is a crucial and effective component of acute urticaria treatment, and intravenous sgAH is preferred as an initial treatment option.

Review
OBJECTIVE
To map topical interventions used to prevent hand-foot syndrome in cancer patients undergoing antineoplastic therapy.
METHOD
This is a scoping review reported in accordance with the recommendations of PRISMA-ScR (extension for scoping review) and the Joanna Briggs Institute Manual. The searches were carried out in the electronic databases CINAHL, Cochrane CENTRAL, EMBASE, LILACS, LIVIVO, PubMed, Scopus, Web of Science; and gray literature (Google Scholar, Pro-Quest).
RESULTS
The searches resulted in 12,016 references and the final sample consisted of 45 studies. A total of 42 topical interventions were identified, including: moisturizing creams, corticosteroids, acids, mapisal, silymarin, and henna. However, urea was the most cited intervention (62%). As for the presentations of the interventions, they varied among creams, ointments, gels, hydrocolloids, decoctions, patches, powders, oils, and soaps.
CONCLUSION
The results allowed reviewing topical interventions, with emphasis on the use of urea and moisturizing creams. However, most of the interventions identified in this review require evaluation in future studies for better understanding of their benefits.

Review
The term Hoigné's syndrome denotes a mimicker of anaphylaxis, which occurs immediately after the parenteral administration of a drug and is likely caused by non-thrombotic pulmonary and systemic drug micro-embolization. It has so far been documented uniquely in case reports and small case series. Because this condition has never been systematically evaluated, we performed a structured literature review (pre-registered as CRD42023392962). The search was carried out in Excerpta Medica, National Library of Medicine, and Google Scholar. Cases with features consistent with anaphylaxis, urticaria, angioedema, asthma, syncope, anxiety, or panic attack triggered by needle phobia, and local anesthetic systemic toxicity were excluded. For the final analysis, we retained reports published between 1951 and 2021, which presented 247 patients with Hoigné's syndrome: 37 children and 211 adults with a male: female ratio of 2.1 : 1.0. The patients presented within 1 min after parenteral administration of a drug (intramuscular penicillin in 90 % of the cases) with chest discomfort, shortness of breath, fear of death, psychomotor agitation, and auditory or visual hallucinations and impairment. Recovery occurred within 30 min. The diagnosis of Hoigné's syndrome was also established in five patients 66-91 years of age with pre-existing cardiovascular or pulmonary diseases, who suddenly died after the administration of penicillin despite not exhibiting the aforementioned symptoms. It was therefore speculated that pulmonary drug micro-embolization induced a lethal cardiovascular compromise in these individuals. Histologic investigations supporting this hypothesis were performed in only one case. The diagnosis of Hoigné's pulmonary drug micro-embolization was established also in five patients with pre-existing cardiovascular or pulmonary diseases, who suddenly died after the administration of penicillin despite not exhibiting the afore mentioned symptoms. Histologic investigations supporting this hypothesis were performed in only one case. In conclusion, Hoigné's syndrome is an uncommon non-immune-mediated reaction. This report seeks to promote broader awareness and knowledge regarding this alarming mimicker of anaphylaxis. Diagnosis relies solely on clinical evaluation.
