A systematic review and meta-analysis on absolute eosinophil counts and the risk of asthma in preschool children with wheezing: An EAACI Task Force Report.

Preschool children with wheezing disorders pose diagnostic and therapeutic challenges and consume substantial healthcare resources. Peripheral eosinophil blood count (EBC) has been proposed as a potential indicator for future asthma development. This review by the European Academy of Allergy and Clinical Immunology (EAACI) Preschool Wheeze Task Force aimed to provide systematic evidence for the association between increased EBC and the risk of future asthma, as well as to identify potential cutoff values. In February 2023, a search of PubMed, EMBASE, and Cochrane Library databases was conducted to identify studies comparing EBCs in preschool children with wheezing who continued to wheeze later in life and those who did not. Included observational studies focused on children aged <6 years with a wheezing disorder, assessment of their EBCs, and subsequent asthma status. No language or publication date restrictions were applied. Among the initial 3394 studies screened, 10 were included in the final analysis, involving 1225 patients. The data from these studies demonstrated that high EBC in preschool children with wheezing is associated with future asthma development, with odds ratios of 1.90 (95% CI: 0.45-7.98, p = .38), 2.87 (95% CI: 1.38-5.95, p < .05), and 3.38 (95% CI: 1.72-6.64, p < .05) for cutoff values in the <300, 300-449, and ≥450 cells/µL ranges, respectively. Defining a specific cutoff point for an elevated EBC lacks consistency, but children with EBC >300 cells/µL are at increased risk of asthma. However, further research is needed due to the limitations of the included studies. Future investigations are necessary to fully elucidate the discussed association.

Indications for surgical treatment of major salivary glands pathologies with epidemiology analysis in adults - cohort study of 1173 cases.

PURPOSE: The review of indications for surgical treatment of major salivary glands in adults hospitalized in the Department of Otorhinolaryngology, Head and Neck Surgery, Medical University of Warsaw. MATERIALS AND METHODS: The retrospective analysis was based on the 1173 postoperative histopathological examinations of the salivary glands collected over a period of 10 years (2010-2020). Analysis included histopathological diagnosis, localization of lesions, multifocality, complete resection, lymph node involvement, as well as demographical data of sex and age. RESULTS: Over half (61.38%) of all indications for surgical treatment of the salivary glands were benign tumors (n = 720) with the most common pleomorphic adenoma, which accounted for 33.5% of all cases (n = 393). The next most frequent group of diagnoses were non-neoplastic diseases of the salivary glands, 24.98% of all cases (n = 293). Malignant neoplasms of the salivary glands accounted for 13.64% of all diagnoses (n = 160). Salivary gland diseases slightly predominated among the female sex, with a particularly pronounced predominance in pleomorphic adenoma. Men, on the other hand, were treated more often for malignant neoplasms. The mean age of the patients was the lowest in the group of non-neoplastic diseases of the salivary glands. The mean age of patients with malignant neoplasms was significantly higher than in other pathologies. The largest tumors size was identified for malignant neoplasms. Diseases of the salivary glands treated surgically were most often located in the parotid gland, with the exception of non-neoplastic diseases, which most often involved the submandibular gland. CONCLUSIONS: Surgical management in pathologies of the salivary glands applies to all types of lesions, both neoplastic and non-neoplastic diseases. Patients with particular diseases are characterized by a different structure of age, sex and location of changes.
