Physical Growth And Sexual Maturation Of Boys In Chapaevsk, Russia, Mary Lee, Oleg Sergeyev, Paige Williams, Susan Korrick, Vladimir Zeilert, Boris Revich, Russ Hauser
Mary M. Lee
We characterized physical growth and sexual maturation in 2,579 boys, ages 10 through 16.99 years, residing in Chapaevsk, Russia in order to establish region-specific reference data. Age-specific norms were established for height, weight, and BMI, and compared to US reference data by z-score analysis, while mean heights and weights by age were compared to published national Russian data. Compared to US boys, height was slightly lower (overall z-score -0.18) at all ages except the oldest (16-16.99 yr), while weight and BMI were moderately lower (overall z-score -0.52 and -0.61, respectively). Chapaevsk boys were significantly taller (1.15 cm) and thinner (-1.28 …

In males, Mullerian inhibiting substance (MIS) mRNA was first detected on the medial aspect of the urogenital ridge early on the morning of day 13 of gestation before testicular differentiation was evident, and localized to the more obvious Sertoli cells later on embryonic day 13. MIS transcripts remained at maximal levels between 14.5 and 17.5 days gestation, while the Mullerian duct involutes, and remained high until birth. MIS gene expression decreased progressively after birth and, as germ cell meiosis increased, became barely detectable in the Sertoli cells of the seminiferous tubules. In female rats, MIS mRNA was first detected in …
Guidelines For The Use Of Growth Hormone In Children With Short Stature., Mary Lee
Guidelines For The Use Of Growth Hormone In Children With Short Stature., Mary Lee
Mary M. Lee
On the basis of the information currently available, the only conditions in which GH therapy appears to be safe and effective in increasing adult height are GH deficiency and, likely, Turner syndrome. Therapy with GH also increases the growth velocity of children with CRI and may increase adult height, but no long-term data are available. Encouraging short-term results have been reported in patients with a few other conditions, such as patients with glucocorticoid-induced growth failure, renal transplantation, and Prader-Willi syndrome, but the data are limited and no long-term studies have been reported; in many other conditions the data are either …
Correlation Of Cognitive Test Scores And Adequacy Of Treatment In Adolescents With Congenital Hypothyroidism., Mary Lee
Mary M. Lee
PURPOSE: To measure the frequency of noncompliance and its possible effect on school achievement test and cognitive test scores in our older patients with congenital hypothyroidism. METHODS: Fifty patients born from 1976 through 1978 were studied at home when they were 14 years of age. Each patient was given a battery of psychometric and school achievement tests, and blood for hormonal assays was drawn without forewarning from 36 of the patients on the day of examination. Efforts were made to improve control after the second year. During the third summer the tests were repeated in 25 of the 29 patients …
