Introduction: Latex allergy is one of the main reasons of anaphylaxis in the operating room. The prevalence of this condition is higher among patients with myelomeningocele. Epidemiological data obtained from Argentine patients is scarce.
Objective: To estimate the prevalence of latex sensitivity and latex allergy in a population of patients with myelomeningocele and to describe associated risk factors.
Population And Methods: Descriptive, cross-sectional, observational study. Family and personal history of allergy, number of surgeries, history of symptoms caused by having been in contact with latex or cross-reactive foods, eosinophil count, measurement of total immunoglobulin E and specific immunoglobulin E levels by means of skin and serologic testing for latex, aeroallergens and cross-reactive fruit.
Results: Eighty-two patients diagnosed with myelomeningocele were assessed: 41 were males and their average age was 15.3 ± 7.66 years old. Out of all patients, two did not complete skin and serologic testing. Among the remaining 80 patients, 16 (19.51%) had latex allergy, 46 (57.5%) were not allergic, and 18 (22%) showed sensitivity but not allergy. Having undergone more than five surgeries was a risk factor associated with latex allergy (p= 0.035). No significant association was observed with the remaining outcome measures.
Conclusion: According to this study, the prevalence of latex allergy in this population of patients is 19.51% and the most important risk factor for this condition is a history of having undergone more than five surgeries.

January 2025
Perioperative anaphylaxis is a serious entity with high morbidity and mortality. Perioperative anaphylaxis can be caused by any of the multitude of medications and substances used in anesthesia and surgery, and the most common causes include neuromuscular blocking agents, antibiotics, antiseptics, latex, and dyes. The differential diagnosis of perioperative anaphylaxis is wide from both an immunologic and a nonimmunologic standpoint.

Background: Endoscopic endonasal techniques, initially developed for sinonasal tumor resection, have revolutionized the approach to orbital lesions. The emergence of endonasal orbital tumor surgery has prompted anatomical studies focusing on the medial orbit, yet there remains a lack of literature on maneuverability lateral to the optic nerve (ON), with current feasibility assessments relying primarily on the plane of resectability (POR).
Methods: Bilateral anatomical dissections were conducted on four latex-injected human cadaveric heads using an endoscopic medial and inferior orbitotomy and superomedial displacement of the inferior rectus muscle (IRM) to access the inferolateral intraconal quadrant.

Background: Anaphylaxis is a systemic allergic reaction that is potentially life-threatening. Occupational anaphylaxis is an anaphylaxis that occurs in an occupational context. In this position paper, we propose diagnostic criteria for occupational anaphylaxis and provide an overview of the current state of knowledge in terms of prevalence, triggers, prevention, and management.

Further, inexperienced triage nurses are generally challenged in differentiating between questions that establish stability and questions that meet other requirements. The aims of the study included exploration of how triage nurses identified critical data elements to facilitate more rapid and accurate patient triage and Emergency Severity Index acuity assignment, perceptions of appropriate location of assessment elements, and identifying common triage processes.

Background: Since the publication of the 2022 Drug Allergy Practice Parameters (DAPP) of the American Academy of Allergy, Asthma & Immunology (AAAAI) and American College of Allergy, Asthma & Immunology (ACAAI), it is unclear the extent to which the simplified and risk-stratified evaluation of cephalosporin allergy has been incorporated into allergy practice.
Objective: We aimed to assess current cephalosporin allergy testing practices using real case examples.
Methods: An 18-question REDCap survey was sent to the 136 members of the Adverse Reactions to Drugs, Biologics and Latex (ARDBL) Committee of the AAAAI between February and April 2023.
