    ABSTRACT: Describe the characteristics of body composition, somatotype, basic physical qualities, dermatoglyphics and bone age regarding sexual maturation stages of boys. A transversal study was carried out in 136 boys, between 10 and 14 years of age. Clinical assessment, physical examination and radiography of wrists and hands to calculate bone age were performed. A tendency of increasing total body mass, stature, body mass index, body bone diameters and muscle circumferences and basic physical qualities was found with the advancing of puberty. No differences were found in dermatoglyphics and somatotype between different stages of puberty maturation. Due to the changes in important parameters of physical training that occur during puberty, it can be concluded that the selection of children and adolescents for sport training and competitions should be based not only on chronological age but also, and mainly on sexual maturation, for better physical assessment and appropriate training for this population.

    ABSTRACT: INTRODUCTION: Indiscriminate serum calcium measurement may lead to the identification of asymptomatic patients with hypercalcaemia, which is caused mostly by primary hyperparathyroidism. OBJECTIVE: To discuss the frequency of hypercalcaemia and the type of assessment of this condition in an outpatient population, with emphasis on the investigation of primary hyperparathyroidism. MATERIAL AND METHODS: In a prospective study 1,049 subjects (age range: 40 to 60 years old) underwent serum calcium and albumin determination and the corrected calcium values were calculated. When there was a rise in the corrected calcium level, ionized calcium, phosphate, parathyroid hormone (PTH) and urinary calcium were measured. RESULTS: The average age was 49.7 ± 13.7 years old, and 188 subjects (17.9%) had elevated corrected calcium levels. Among these, 90 patients underwent the second investigation and 19 (2%) remained hypercalcemic. Ionized calcium levels (average: 1.2 ± 0.01 mmol/L) were normal in all subjects. Urinary calcium was 185.8 ± 111.8 mg/24 hours. PTH levels (average: 46 ± 11.8 pg/mL) were elevated in three subjects whose parathyroid scintigraphies were normal. DISCUSSION: The fall in the frequency of hypercalcaemia based on corrected serum calcium levels and mostly after determination of serum ionized calcium suggests that determinations of serum free calcium are a better screening test. No subject was diagnosed with hyperparathyroidism, what suggests an uneven distribution of the disease in different populations. CONCLUSION: Routine serum calcium determinations in asymptomatic patients must be questioned. When serum calcium determination is thought necessary, ionized calcium levels should be favored.
