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.

Disseminated Coccidioidomycosis as the First Presentation of a C-Terminal NFKB2 Pathogenic Variant: A Case Report and Review of the Literature.

Introduction: Although most cases of coccidioidomycosis are subclinical or self-limited respiratory disease, 1% lead to extrathoracic dissemination and become fatal, especially in patients with an associated immunodeficiency. Up to 30%-50% of patients with defects in cell-mediated immunity, those with AIDS and recipients of solid-organ transplants, may develop disseminated coccidioidomycosis (DC). Within the primary immunodeficiencies, an uncommon group is caused by C-terminal NFKB2 pathogenic variants.

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.
