Introduction: Transplantation is the treatment of choice in patients with chronic kidney disease (CKD). It requires immunosuppression, which predisposes to the development of complications. Chronic rhinosinusitis (CRS) is one of the most important. Objective: To compare the characteristics of patients with CKD with and without CRS undergoing renal transplantation protocol in a concentration Hospital in Puebla, Mexico. Methods: Comparative, cross-sectional, retrospective study in patients in a tertiary care hospital with CKD and undergoing renal transplantation protocol. The SNOT-22 and Lund-Mackay scales were applied. Descriptive statistics and Mann-Whitney U test, Fisher's exact test and Phi coefficient were used; p<0.05 was considered significant. Results: 360 patients were recruited, 49 presented CRS, prevalence: 13.61%. Means: age: 39.22 ±12.09 years and evolution time: 17.73 ±5...

Background: Juvenile laryngeal papillomatosis (JLP) is a chronic benign disease from viral etiology, whose clinical course can be aggressive. In Mexico, the Human Papillomavirus (HPV) genotypes that cause this disease have been poorly studied. Objective: To identify the HPV genotypes in patients with JLP in a reference Hospital in Puebla, Mexico. Mehods: A retrospective descriptive study was performed in patients with JLP attended in a 3rd level care of the Instituto Mexicano del Seguro Social in Puebla, México, from 2018 to 2021. Medical records were revised. In all patients, HPV identification was performed by polymerase chain reaction for genomes 6, 11, 16 and 18 using specific oligonucleotides. Descriptive statistics were applied. Results: 9 patients were included, 56% women, mean age 9.5 ±5.7 years; 7 patients were HPV-11 positive and 2 HPV-6. The mean age at diagnosis was 2.35 ±...
