Growth of Argentinian girls with Turner syndrome.
Growth data on 254 patients with Turner syndrome from Argentina-120 with XO karyotype and 134 with other chromosomal abnormalities-were analysed. Birth weight and height were significantly reduced. Ninety patients had received oestrogen treatment from a mean age of 14-0 years (SD 1.2) and 17 patients had spontaneous menarche. Patients who underwent spontaneous menarche had a small growth spurt. Final height was slightly higher (139.8 cm SD 5.6), though not significantly different from the mean adult height of the whole sample (137.9 cm SD 5.7). Mean adult height was 3.73 SD below mean of the normal local population. Mean height velocities from birth to maturity are very similar to those found in other samples. Distance standards were prepared by fitting a fifth-degree polynomial to the interpolated mean heights at each 0.5 year of age, and to the raw SD. Selected centiles were then calculated from the smoothed values. Differences between adult height in local Turner syndrome girls and local normal population are very similar to the same Turner-normal differences described in other communities. Standards presented here are useful for evaluating Turner syndrome patients from Argentina, and may also be used by those with similar growth pattern in their normal population.
