Abstract

ROMAN, Rossana et al. Spontaneous growth of 83 Chilean girls with Turner's syndrome. Rev. méd. Chile [online]. 2002, vol.130, n.9, pp.977-984. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872002000900003.

Background: Short stature is the main feature of patients with Turner's syndrome. There is limited information regarding the spontaneous growth of these patients in Chile. Aim: To develop a specific growth chart for Chilean patients with Turner's syndrome. Material and methods: We retrospectively analyzed 668 height measurements from 85 Chilean girls, born after 1968, with 45XO karyotype (minimum 15%), and without an Y chromosome fragment. Patients with hormonal therapy, such as growth hormone or estrogen, except thyroid hormone replacement, were excluded. Results: The karyotypes were 60% 45XO, 25% 45XO, 46XX, and 15% other complex mosaics. The birth length was 46.8 ± 2.1 cm. The final height of our patients was 138,20 ± 7,0 cm. Conclusions: The final height achieved by our patients, is similar to Argentinian and Japanese patients, but is below the mean stature reported for Scandinavian and Northamerican patients who achieve a mean adult height of approximately 147 and 142 cm respectively. The birth length is also lower than that reported in those studies (Rev Méd Chile 2002; 130: 977-84).
