Abstract:
This study aims to evaluate the sensitization distribution of aeroallergens in patients with allergic conjunctivitis (AC) living in a temperate subhumid region and to describe the prevalence in a Mexican cohort. A total of 761 patient records were revisited, including the results of the skin prick test (SPT) for 45 aeroallergens. We found 292 patients with AC and a positive SPT in a 5-year period. The most frequent aeroallergens include dust mites (69.2% for Dermatophagoides pteronyssinus and 47.6% for Dermatophagoides farinae), trees (36% for cypress and 22.6% for ash), animals (33.9% for dogs and 26.7% for cats), and grasses (21.2% for Paspalum notalum and 19.9% for Poa pratensis). Among the studied population, a prevalence of 38.4% for the disease was calculated. House dust mites were responsible for most sensitizations found in the studied population. There is a high prevalence of AC in the selected cohort during the period studied.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
