Abstract Objective: To characterize a cohort of pediatric thyroid cancer patients, focusing on clinical features and outcomes stratified by age. Subjects and methods: This retrospective analysis included 63 pediatric differentiated thyroid cancer patients treated at a Portuguese pediatric reference hospital over a period of 20 years. Data extracted from clinical records covered demographics, clinical presentation, family history, tumor characteristics, treatment modalities, complications, disease status, and survival outcomes. Patients younger than 12 years were compared to those aged 12 and older. […]

ABSTRACT Objectives To evaluate the ability of BMI, WC and WHtR to discriminate hyperglycemia in young people, and to determine whether there is an increase in the accuracy with the addition of WC and/or WHtR to BMI. Subjects and methods A cross-sectional study was conducted on 1,139 schoolchildren aged 6 to 17 years from Northeastern Brazil. Body weight, height, WC and fasting glucose levels were measured, and the BMI and WHtR were calculated. The presence of hyperglycemia was defined as […]

Human growth hormone (hGH) replacement therapy has been widely available for clinical purposes for more than fifty years. Starting in 1958, hGH was obtained from cadaveric pituitaries, but in 1985 the association between hGH therapy and Creutzfeldt-Jakob disease was reported. In the same year, the use of recombinant hGH (rhGH) was approved. Side effects of rhGH replacement therapy in children and adolescents include rash and pain at injection site, transient fever, prepubertal gynecomastia, arthralgia, edema, benign intracranial hypertension, insulin resistance, […]

Cushing’s syndrome (CS) results from prolonged exposure to supraphysiological levels of circulating glucocorticoids, endogenously or exogenously derived. Although rare in childhood, CS remains a difficult condition to diagnose and treat. A multidisciplinary approach and close collaboration with adult colleagues is adopted at most large centres that manage pediatric CS patients. Although pediatric protocols are derived from adult data, significant differences exist between adult and childhood CS. Furthermore, long term outcome parameters including final height, bone mineral density, reproductive function, body […]

OBJECTIVES: To evaluate the neonatal screening program for congenital hypothyrodism (CH) of the Health Secretariat of the State of Santa Catarina and determine the prevalence of CH among screened children. METHODS: 390,759 newborns were screened for CH between 01/94 and 12/98 to evaluate: the program coverage, children’s age at the time of the 1st blood sample for TSH measurement, time to transport blood samples to the core laboratory (LACEN), time to obtain TSH results, time to locate children with abnormal […]
