Sick building syndrome: do outdoor pollutants and pollen affect it?

Introduction: Sick building syndrome (SBS) refers to non-specific complaints, including upper-respiratory irritative symptoms, headaches, fatigue, and rash, which are usually associated with a particular building by their temporal pattern of occurrence and clustering among inhabitants or colleagues. The aim of the study was to determine the association between the clinical manifestations of sick building syndrome with outdoor pollutants and airborne pollen.

Methods: It was a descriptive and prospective observational study conducted from November 2021 to April 2022.

Hypersensitivity reaction to Abiraterone, successful desensitization protocol in prostate cancer patient.

Introduction: In prostate cancer, androgens are key in the growth of both normal prostate and cancer cells. Abiraterone acetate inhibits CYP17, an important target in prostate cancer given its central role in the production of adrenal and tumor-derived androgens. Although abiraterone is generally well tolerated, common adverse effects such as hypertension, hypokalemia, and hepatotoxicity have been reported.

The association of air pollution in respiratory allergy: Its impact in an industrial city.

Background: Asthma and allergic diseases have increased in recent decades and are more common in industrialized countries. Industrial areas with a considerably high number of inhabitants and vehicles can favor the presence of serious air pollution and therefore the appearance and exacerbation of respiratory allergy symptoms. The objective of this study was to determine the relationship between exposure to environmental pollutants with exacerbation of respiratory allergy.

Patient-important outcomes in clinical trials of atopic diseases and asthma in the last decade: A systematic review.

Background: Randomized Clinical Trials (RCTs) are important tools to establish the effects of a given intervention. Investigators should focus on outcomes that patients perceive: patient-important outcomes (PIOs), clinical endpoints that patients value directly and reflect how they feel, function, or survive. However, it is easier to consider surrogated outcomes to reduce costs and achieve better-looking results.

Anaphylaxis in Cold Induced Urticaria: A Case Report and Review of The Literature.

Cold-induced urticaria is considered as a subtype of physical urticaria and also the second most common type of chronic inducible urticaria. Contact with cold surfaces or the environment may cause systemic reactions, especially during aquatic activities. A 22-year-old female patient with a history of sulfa drug allergy began her condition 2 years before the presence of generalized pruritic erythema with hives as well as 2 episodes that had been characterized by facial angioedema and syncope 3-5 minutes after being in contact with cold air or surfaces.

[Environmental pollution and allergy].

Air pollution, climate change, and the decrease of biological diversity are major threats to human health. In the past decades, an increase in allergic diseases, including asthma and rhinoconjunctivitis, has been observed. Up to 40 % of the world population may have an allergic disease, which represents a significant impact on the quality of life of those who suffer from it, and environmental pollution is one of the causes of its presentation.

Knowledge of healthcare providers in the management of anaphylaxis.

Introduction: Anaphylaxis is defined as a severe, life-threatening systemic hypersensitivity reaction. Early diagnosis and treatment of a severe allergic reaction requires recognition of the signs and symptoms, as well as classification of severity. It is a clinical emergency, and healthcare providers should have the knowledge for recognition and management.

Allergy education and training for physicians.

The increasing prevalence of allergic diseases has placed a significant burden on global healthcare and society as whole. This has necessitated a rapid development of "allergy" as a specialist area. However, as allergy is so common and, for most, relatively easy to diagnose and control, all clinicians need to have basic knowledge and competence  to manage  mild disease and recognize when referral is required.

Harmonizing allergy care-integrated care pathways and multidisciplinary approaches.

There is a wide time gap between the publication of evidence and the application of new knowledge into routine clinical practice. The consequence is sub-optimal outcomes, particularly concerning for long-term relapsing/remitting conditions such as allergic diseases. In response, there has been a proliferation of published guidelines which systematically review evidence for the gold-standard management of most allergic disorders.

Current situation of allergy education in Mexico and other parts of Latin America.

Allergic diseases are one of the most frequent chronic diseases in the world. It has been established that there is a worldwide epidemic of allergic diseases; therefore, the treatment of allergies should be acknowledged as a worldwide priority and the specialty of allergy should be considered an important field in medicine. Due to the fact that allergic diseases involve many organs, and Allergy and Clinical Immunology is one of the specialties in which physicians may be trained to treat patients of all ages, the subject in medical schools is not always taught as an individual specialty but often as part of another subject such as internal medicine or pediatrics.

Hypersensitivity reactions to paclitaxel: The Mexican experience of rapid desensitization.

Background: Taxanes adjuvant therapy is recommended in certain high risk or metastatic tumors, particularly in lung and breast cancer, but also in other types of cancer like ovarian. The incidence of severe adverse drug reactions to paclitaxel is of approximately 10%.

Objectives: Analyze type I hypersensitivity reactions to paclitaxel and their management in the Mexican population.

Rituximab desensitization in pediatric acute lymphoblastic leukemia with severe anaphylaxis.

Introduction: Hypersensitivity reactions (HSRs) to rituximab occur during the first infusion in 29% to 40% of patients. Commonly, these hypersensitivity reactions are the result of a release of cytokines, although IgE mediated reactions have also been reported.

Case Report: A 7-year-old female patient with diagnosis of CD-20 positive acute lymphoblastic B-cell leukemia was included in a pilot study that consisted of two doses of rituximab treatment in the induction to remission phase by the pediatric hematology service; 30 minutes after the first administration of 300 mg of rituximab the patient started with generalized rash, nausea, vomiting, tachycardia, dyspnea, foreign body sensation in throat, oxygen desaturation until 89% and hypotension; therefore, the infusion of rituximab was suspended, and intramuscular epinephrine was administered as well as intravenous hydrocortisone and chlorphenamine and supplemental oxygen supply with adequate resolution of symptoms.

Rapid desensitization to brentuximab vedotin after severe anaphylaxis in the treatment of refractory Hodgkin's lymphoma.

Introduction: Brentuximab vedotin is a monoclonal antibody drug conjugate used for the treatment of patients with Hodgkin lymphoma. Hypersensitivity reactions to brentuximab vedotin may include cutaneous, cardiovascular, respiratory, gastrointestinal and neurological signs and symptoms.

Case Report: We present the case of a 23-year-old Mexican female with stage IV progressive classical nodular sclerosing Hodgkin lymphoma who received multiple previous chemotherapy regimens.

Successful oxaliplatin desensitization protocol in a patient with colorectal metastatic cancer.

Introduction: Platinum compounds are frequently used for the treatment of colorectal cancer as initial chemotherapy. Oxaliplatin is a third-generation platinum used for the treatment of stage III colorectal cancer and is associated with hypersensitivity reactions. The incidence of hypersensitivity reaction is approximately 12%, with 1-2% of patients developing moderate to severe reactions.
