Sensitization to Aeroallergens in a Mexican Cohort with Allergic Conjunctivitis: A Cross-sectional Retrospective Study Conducted in Ángeles Puebla Hospital.

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.

Metabolic Changes in Children that Received Chemotherapy.

Cancer treatments are associated with short and long-effects. Epidemiological reports have revealed clinical features of metabolic syndrome (MS), obesity or overweight in young cancer survivors. The aim of the study was to examine the prevalence of unhealthy weight status and risk factors associated with MS related to chemotherapy. We study 52 pediatric cancer patients and analyze cholesterol, triglycerides, glycosylated hemoglobin, body mass index, waist circumference (WC), FINDRISC test. All the parameters were analyzed according to the percentile corresponding to sex and age of each child. The data show an important modification in weight, body mass index, and WC as in triglycerides, and cholesterol that could be associated with the development of MS. The variance analysis showed that the WC, triglycerides, and cholesterol are statistically correlated in our population. A follow-up for MS in children cancer survivor should be considered necessary.

P-glycoprotein Activity Correlates With Treatment Response in 2 Leukemia Child Patients.

Acute lymphoblastic leukemia is the most important childhood cancer. Multidrug resistance is an important factor of poor prognosis. We present the P-glycoprotein (P-gp) activity in 2 patients with different outcomes. Both patients had B-cell acute lymphoblastic leukemia; they were responding properly to the treatment, but one of them had an increment in the P-gp activity that correlates with an increment in the disease manifestation, the patient had to be hospitalized and developed sepsis and subsequently died. P-gp levels were correlated with disease progression. P-gp activity needs to be evaluated during treatment to assess and prevent disease relapse or the patient´s death.
