    Follow-up of children and adolescents with short stature: the importance of the growth rate
    (Associação Paulista de Medicina - APM, 2005-05-01) Strufaldi, Maria Wany Louzada [UNIFESP]; Silva, Edina Mariko Koga da [UNIFESP]; Puccini, Rosana Fiorini [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    CONTEXT AND OBJECTIVE: Short stature is defined as a height of more than two standard deviations below the average for a given age and sex in a reference population. The objective was to describe follow-up conducted among short-stature children and adolescents. DESIGN AND SETTING: Descriptive study, at the Growth outpatient clinic, Department of Pediatrics, Universidade Federal de São Paulo (UNIFESP). METHODS: The study included 152 patients aged 2 to 15 years who had height for age of less than P5, on the National Center for Health Statistics curve. The children underwent nutritional evaluation, and several variables relating to height and growth rate were calculated to establish etiological diagnosis. Bone age was evaluated by X-ray. RESULTS: The majority (63.2%) were male. In 77.8%, the stature observed was within the family pattern. Among the 99 patients followed up for more than 6 months, 17.2% presented inadequate growth rates. The preponderant etiological diagnosis for short stature was familial/constitutional in 58.6% of the cases; 27 patients (34.2%) with adequate growth rate presented bone age alterations. Even with inadequate growth rates, 75% of such patients had a normal result from growth hormone stimulation testing. Close to 90% of patients with a diagnosis of short stature of familial/constitutional origin and intrauterine growth retardation presented adequate growth rate. The genetic etiology was significantly characteristic of patients with inadequate growth rate. CONCLUSION: Growth rate assessment must form part of the investigation and follow-up of short-stature cases. However, its utilization and validity should form part of an overall view of each patient.

    A importância do consumo dietético de cálcio e vitamina D no crescimento
    (Sociedade Brasileira de Pediatria, 2008-10-01) Bueno, Aline L.; Czepielewski, Mauro A. [UNIFESP]; Universidade Federal do Rio Grande do Sul; Universidade Federal de São Paulo (UNIFESP); UFRGS Faculdade de Medicina Programa de Pós-Graduação em Ciências Médicas: Endocrinologia e Nutrição
    OBJECTIVE: To investigate the role of dietary calcium and vitamin D in the process of growth and development of children and adolescents, focusing in particular on the prevention and treatment of delayed growth caused by nutritional deficiency. SOURCES: Information was gathered from articles published in the last 2 decades, from searches on the databases SciELO, PubMed and Medline, technical books and publications of international organizations. SUMMARY OF THE FINDINGS: Growth is influenced by intrinsic (genetic and metabolic) and extrinsic factors (environmental factors such as diet, health, hygiene, housing and access to health services). Among the nutritional factors are vitamin and oligoelement deficiencies which may be associated with malnutrition or caused by insufficient absorption. Since calcium is one of the main mineral components of bone tissue, it is essential for adequate bone formation and, considering that vitamin D plays an important role in calcium metabolism, a diet with insufficient quantities of these nutrients can impact on the formation of the skeleton and on the process of growth and development. CONCLUSIONS: In children and adolescents, low intake or low absorption of calcium and vitamin D may limit their statural growth, and it is necessary to supply sufficient quantities of both during the critical growth phases.
