“…The onset of spontaneous puberty in these patients took place at a mean age of ll.8SD 1-Tyears (range 9.6-14-0years) and menarche occurred at 13.6SD 1.5years (range 11-16.1 years). Both pubertal events were 1 year delayed with regard to the Argentine normal population values (Lejarraga, Castro andCuminsky 1976, Lejarraga, Sanchirico andCusminsky 1980). Two of these 17 patients had a karyotype Ann Hum Biol Downloaded from informahealthcare.com by QUT Queensland University of Tech on 11/01/14…”

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.

“…GH provocative tests were normal, with extremely low serum IGF-I and IGF-binding protein (IGFBP)-3. She spontaneously started puberty at 12.5 yr, reaching normal menarche at 14.5 yr (12,13). A low growth spurt, with peak height velocity of only 4.2 cm/yr (below third percentile; normal, 7.5 cm/yr for age 13.8 yr) was noted.…”

A Novel Missense Mutation in the SH2 Domain of theSTAT5BGene Results in a Transcriptionally Inactive STAT5b Associated with Severe IGF-I Deficiency, Immune Dysfunction, and Lack of Pulmonary Disease

A novel STAT5B p.Phe646Ser mutation has been identified in a patient with clinical characteristics of STAT5b deficiency. Only the second STAT5B missense mutation identified, its lack of transcriptional activities despite GH-induced phosphorylation, confirms the crucial role of STAT5b for regulating the expression of IGF1 and provides insights into the importance of the SH2 βD' strand for full STAT5b transcriptional activities. Whether the phosphorylated p.Phe646Ser variant retained functions that prevented pulmonary distress remains unresolved.

“…In our group of patients, the menarche was not delayed, mean age being: 12.4 years (normal 12.5 ± 1.2) (Lejarraga et al 1980). At that time their renal function was normal, but when the glomerular filtration rate declined, they became oligomenorrhoeic or amenorrhoic.…”

The effects of chronic renal failure on the hypothalamic-pituitary-ovarian axis in 25 girls, aged 9.1 to 20.9 years (mean 13.8) were studied. Twelve patients on conservative treatment (group A) had serum creatinine values between 176.8 and 1502.8 \g=m\mol/l; 9 patients were on haemodialysis (group B); and 12 patients had received a renal transplant (group C). Tanner stage of breast development was delayed relative to chronological age in 5 out of 18 patients. Serum oestradiol was normal or low when related to pubertal stages in all groups. Serum LH was elevated in group A and B patients, but normal in group C patients. Serum FSH was elevated in 6 out of the 21 patients in group A plus B, and in 2 out of the 12 patients in group C. Serum PRL was elevated in 12/12, 6/8, and 4/11 patients in group A, B, and C respectively. After GnRH administration to 4 patients in group A, 3 showed delayed or absent gonadotropin response; all 4 patients studied in group C showed normal gonadotropin response. The data indicate a decreased E2 secretion, abnormal gonadotropin and PRL levels and a blunted gonadotropin response to GnRH in girls with chronic renal failure.These results seem to indicate an alteration of the hypothalamic-pituitary unit that can be reversed after successful renal transplantation.
