The role of molecular diagnosis in anaphylactic patients with dual or triple-sensitization to Hymenoptera venoms.

Background: The poly-sensitization to Hymenoptera venom makes it difficult to select genuine allergens for immunotherapy and increases patients' costs. The objective of this study was to determine the culprit allergen in dual or triple-sensitized patients to three Hymenoptera venoms through molecular diagnosis and evaluating the results of incorporating the molecular diagnosis with skin tests.

Methods: Thirty-two patients with anaphylactic reactions and dual or triple-sensitization to Hymenoptera venoms in skin tests entered this study.

Immune endotyping and gene expression profile of patients with chronic rhinosinusitis with nasal polyps in the aspirin-exacerbated respiratory disease (AERD) and the non-AERD subgroups.

Background: Chronic Rhinosinusitis (CRS) is a paranasal sinus inflammatory disease and is divided into two subgroups defined as CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). CRSwNP displays a T helper (Th)2 biased phenotype, and based on sensitivity or tolerance to aspirin or non-steroidal anti-inflammatory drugs (NSAID), is further subdivided into Aspirin-exacerbated respiratory disease (AERD) and non-AERD groups. Considering the challenge of diagnosis and treatment in patients with CRSwNP, particularly the AERD subtype, and the significance of endotyping in these patients, we examined the immune profile and endotyping based on gene expression analysis in the AERD and the non-AERD groups of patients with CRSwNP.

Risk factors and surgical approaches in neglected subaxial cervical spine fractures-dislocations: Experiences with two cases and literature review.

This case report describes our experience of surgical strategies of two patients with neglected subaxial cervical spine fracture-dislocation that came to our center with subsequent follow-ups. Subaxial cervical spine fracture-dislocation must be immediately diagnosed and treated. However, it can be neglected in some cases, especially in developing health care systems and patients with low socioeconomic status.

Prone extension views in cervical MRI: A case-driven Novel approach.

The cervical spinal canal has a wide range of motion and specific biomechanics involved with different pathologies that may cause dynamic cord compressions. This study has introduced new protocol for acquiring an extension view of cervical MRI to assess dynamic cervical spinal canal compromise. We posit that dynamic MRI comprising extension view in prone position could be a practical option when deciding the best approach in treating challenging patients.

Diagnosis and selection of alternative antibiotics in beta-lactams hypersensitivity reactions: Current recommendations and challenges.

Beta-lactam (BLM) antibiotics, including amino-penicillin and cephalosporins, are typically the first-choice treatment for bacterial infections. However, adverse reactions to these antibiotics are frequently reported, causing non-allergist physicians to select alternative broad-spectrum antibiotics that can have harmful consequences. Patients with unclear histories of hypersensitivity reactions to BLMs should undergo an allergy workup to establish a firm diagnosis, particularly when different drugs are prescribed simultaneously.

We aimed to evaluate early and delayed adverse effects after coronavirus disease 2019 (COVID-19) vaccine among Iranian pediatrics and adolescents in a national survey.

Asthma Management System in Primary Care Based on Global Initiative for Asthma and Snell's Drug Interaction: Accuracy and Usability.

Background: The two main pillars of asthma management include regular follow-up and using guidelines in the treatment process. Patient portals enable regular follow-up of disease, and guideline-based decision-support-systems can improve the use of guidelines in the treatment process. Based on the Global Initiative for Asthma (GINA) and Snell's drug interaction, asthma management system in primary care (AMSPC) includes the capabilities of both mentioned systems.

Central nervous system hydatidosis around the world: a systematic review.

Introduction: Echinococcosis is a chronic disease caused by Echinococcus species. The central nervous system (CNS) hydatidosis is still a major concern, especially in endemic countries, due to non-specific features and late diagnosis and treatment. This study aimed to provide a systematic review to elucidate the epidemiology and clinical characteristics of CNS hydatidosis worldwide over the past decades.

Doxycycline Improves Quality of Life and Anosmia in Chronic Rhinosinusitis With Nasal Polyposis: A Randomized Controlled Trial.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a complex disorder and effective treatment remains a major challenge. Some antibiotics with anti-inflammatory properties are reported to have potential to be used as an adjunct therapy in the management of chronic airway inflammation.

Objective: The aim of this study was to evaluate the efficacy of doxycycline in CRSwNP.

Diversity of malignancies in patients with different types of inborn errors of immunity.

Genetic defects in the development, maturation, and/or function of the immune cells can lead to Inborn errors of immunity (IEI) which may predispose patients to malignancies. The overall risk for cancer in children with IEI ranges from 4 to 25% and the type of malignancy is highly dependent on the specific mutant gene underlying IEI. We investigated 3056 IEI patients registered in the Iranian national registry between the years 1999 and 2020 in this retrospective cohort study.
