Objective. The aim of our study was to evaluate the prognostic value of reticulocyte hemoglobin content for diagnosis of iron deficiency in 6-24-month-old children.Material and methods. Children aged 6 to 24 months were consulted for suspected iron deficiency in the outpatient department in 2006-2007. Criteria for inclusion into the study were normal birth time and weight, no infection during the last two weeks before blood sampling (Creactive protein <5 mg/L), no iron supplements 1 month before the study. Red blood cell, reticulocyte indices and biochemical tests were analyzed. A total of 180 children were enrolled in our study. Iron deficiency was diagnosed when at least two of four parameters (ferritin, transferrin, transferrin saturation, and soluble transferrin receptors) reflected iron deficiency.Results. According to our criteria of iron deficiency, patients were divided into two groups: 116 had iron deficiency and 64 had normal iron stores. The iron deficiency group had significantly lower hemoglobin, mean corpuscular hemoglobin, mean corpuscular volume, reticulocyte hemoglobin content, ferritin, soluble transferrin receptors, iron and higher red cell distribution width, transferrin, and transferrin saturation (P<0.05) compared with the normal iron store group. Reticulocyte hemoglobin content, ferritin, and transferrin saturation had the highest sensitivity and specificity (76.6% and 78.4%, 81.3% and 81.9%, 85.9% and 87.9%, respectively).Conclusion. Reticulocyte hemoglobin content is comparable test with ferritin and transferrin saturation and can be used to detect iron deficiency in 6-24-month-old children.
Background: Thyroid cancer (TC) is a rare condition in children. It may be associated with radiation, iodine deficiency or familial inheritance. Aims: The objectives of this study were to analyse the prevalence and incidence trends over 3 decades and clinical features of TC in the paediatric population in Lithuania. Methods: We reviewed all TC cases diagnosed in children aged less than 18 years during the period 1980-2014 using medical records from 3 main hospitals in Lithuania where such TC cases are managed. Results: During the 35-year period (1980-2014) there were 57 cases (45 females) of TC in children in Lithuania. The mean age at the time of diagnosis was 14.51 ± 0.52 years. The crude incidence rate of TC ranged from 0 to 0.93 cases per 100,000 children per year and the mean annual increase was 5.26% (p < 0.001). Papillary carcinoma was the most common histological type (73.7%). No association was found between the incidence of TC and the reported areas of radioactive contamination after the Chernobyl accident. In total, 8.8% of patients had secondary TC after initial radiotherapy of a primary oncologic disease. Conclusion: The incidence of TC in the Lithuanian paediatric population between 1980 and 2014 ranged from 0 to 0.93 cases per 100,000 children per year and there was a 5.26% annual increase (p < 0.001), most probably related to the increased use of ultrasound testing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
