  • Objectives: Purpose of this study is to analyze and to estimate which and how much genetic and environmental factors have affected on growth. Also, a method of final height prediction can be developed from this study results. Methods: Correlation analysis and categorical regression analysis were conducted between genetic and environmental factors correlated with the final adult height, through survey from 171 male. Results: Mid parental height, neonatal body weight, intake frequency of beef, chicken, milk, fruits and coffee, sleep quantity and quality during the elementary school and sleep quantity during the middle school have affected on the final adult height. And a regression equation with 0.494 for coefficient of determination was obtained. Conclusions: Mid-parental-height has the most affected on the final adult height. Among environmental factors, food and sleep have significantly affected, but exercise doesn't. Among foods, meal, beef, and milk intake have remarkably affected on the final height, and chicken and fruit also have affected in some degree, but coffee has affected badly. Among sleep habits, sleep quantity during the elementary school has the most affected, sleep quality during the elementary school and sleep quantity during the middle school also have affected in some degree on final height. The younger the age is, the more sleep have affected and sleep quantity have more affected than sleep quality. Neonatal weight also has remarkably affected on the final height. Through this analysis, the final adult height can be predicted using regression equation which covers 49.4% of genetic and environmental factors.

  • Purpose : The purpose of this study was to evaluate the factors affecting the final adult height and total height gain in idiopathic and organic growth hormone deficient(GHD) children after growth hormone(GH) treatment. Methods : Thirteen patients with idiopathic GHD and 22 patients with organic GHD who had been treated with GH and attained adult final height were included in this study. Factors which could affect the final adult height(FAH) and total height gain, were evaluated. Results : Height SDS(standard deviation score) at initial GH treatment in idiopathic GHD was significantly shorter than that in organic GHD($-4.13{\pm}1.28$ vs $-1.66{\pm}1.06$, P<0.001). Growth velocity during the first year of GH treatment was $9.69{\pm}3.19cm$(idiopathic GHD) and $7.87{\pm}3.65cm$(organic GHD). Height(SDS) at puberty in organic GHD was significantly greater than in idiopathic GHD ($-0.55{\pm}1.25$ vs $-2.28{\pm}0.95$, P<0.001). Final adult height(SDS) was significantly greater in organic GHD than in idiopathic GHD($0.22{\pm}1.06$ vs $-1.44{\pm}0.84$, P<0.001). In idiopathic GHD, total height gain (SDS) was most significantly correlated with midparental height minus initial height(MPH-IH)(SDS) (r=0.886, P<0.001). Total height gain(SDS) was more significantly correlated with MPH-IH(SDS) and prepubertal height gain(SDS) in idiopathic GHD(r=0.640, P=0.01, r=0.801, P<0.001). Conclusion : Final adult height was greater in organic GHD than in idiopathic GHD patients. While total height gain(SDS) was more pronounced in children with lower initial height compared to MPH, absolute final adult height was influenced by height at puberty. To improve the final adult height in children with GHD, height at onset of puberty must be increased by early diagnosis and continuous treatment with optimal doses of GH. There results should be evaluated with more patients.

  • Since the advent of growth hormone(GH), children with a wide variety of growth disorders have received GH treatment. In GH deficiency(GHD), Turner syndrome, chronic renal failure, children born small for gestational age, Prader-Willi syndrome, and idiopathic short stature, the therapeutic effects and safety profile of GH are reviewed. GH therapy has been clearly shown to improve height velocity and final adult height in a variety of pediatric conditions in which growth is compromised irrespective of GHD. Early initiation and individualization of GH treatment has the potential to normalize childhood growth. The supra-physiological doses of GH have been shown to increase height velocity during childhood and final height in non-GHD conditions. Adverse events during GH therapy are uncommon and often not drug related. However continued surveillance into adult life is crucial, especially in children receiving supra-physiological doses or whose underlying condition increases their risk of adverse effects.

  • Purpose : The hope that arresting pubertal developement might increase final adult height has led to an attempt to use GnRH agonist (GnRHa) in children with early puberty and poor growth prognosis. We investigated the growth-promoting effect of GnRH agonists with or without growth hormone (GH) in girls with early puberty and decreased predicted adult height (PAH). Methods : Thirty five girls with advanced bone age and early pubertal signs were randomized for treatment for about 1 year with monthly GnRHa in group 1 (n=18), or with a combination of GH and GnRHa in group 2 (n=17). The following growth parameters were compared between groups, and the difference ($\Delta$) before and after treatment : chronological age (CA), bone age (BA), $\Delta$(BA-CA), height (HT), target height (TH), predicted adult height (PAH), $\Delta$ (TH-PAH), serum insulin-like growth factor (IGF-1) and insulin-like growth factor binding protein (IGFBP-3). Results : Before treatment, BA, TH, PAH Standard deviation scores (SDS), $\Delta$(TH-PAH) were not different between the two groups, but CA was higher in group 2 and $\Delta$(BA-CA) were higher in group 1 (P<0.05). After $1.06{\pm}0.93$ year of treatment, $\Delta$ (BA-CA) decreased and there were significant changes in PAH and $\Delta$ (TH-PAH), especially in group 2 (P<0.05 in group 1, and P<0.001 in group 2). In both groups, IGF-1 and IGFBP-3 were not different before and after treatment, but after treatment, IGF-1 level in group 2 was marginally higher than IGF-1 in group 1 (P<0.1). Conclusion : Compromised predicted adult height in girls with early puberty and advanced bone age was significantly improved with GnRH with/without GH treatment in the short-term period. The addition of GH to GnRHa results in a significant increase in PAH compared to GnRHa alone because GnRHa suppressed growth hormone-IGF-1 axis. For comparison of final adult height, further longitudinal follow-up will be needed.

  • Purpose : Short stature is an important complication that impairs the quality of life in survivors of childhood brain tumors. We studied their final adult height (FAH) to evaluate risk factors for short stature. Methods : We reviewed the medical data of 95 survivors of childhood brain tumors (64 males and 31 females) who had been followed up from 1982 to 2006, reached FAH, and had a more than five year-disease-free survival. Results : Final adult height standard deviation score (FAHTSDS: $mean{\pm}SD$) of the patients was lower than those of general population ($-1.15{\pm}1.72$), HTSDS at diagnosis ($-0.13{\pm}1.57$), and target HTSDS ($-0.49{\pm}0.69$). FAHTSDS of craniopharyngioma patients did not decrease ($0.57{\pm}1.17$), but those of germ cell tumor and medulloblastoma patients were significantly reduced ($-1.20{\pm}1.45$, $-2.70{\pm}1.46$; P<0.05). The patients treated with craniospinal radiation or chemotherapy had lower FAHTSDS ($-1.93{\pm}1.58$, $-2.27{\pm}1.44$; P<0.01). In the spinal irradiation group, the younger the age at diagnosis was, the more the loss of FAH (r=0.442, P<0.01). Growth hormone replacement (GHR) didn't improve FAHTSDS, but starting GHR under 12 years was an independent factor for improving FAH once treatment methods were taken into account (P=0.01). Conclusion : The younger age at diagnosis, spinal radiation and chemotherapy were all important risk factors of height loss, and height gain was expected in patients who received GHR under the age of 12 years. Therefore, regular check-ups of growth and early intervention with growth hormones are needed for high risk groups to improve FAH.

  • Purpose : GnRH analogues(GnRHa) are used to treat central precocious puberty(CPP). However, in some patients, the GV decrease is so remarkable that it impairs predicted adult height(PAH); and there fore, the addition of growth hormone(GH) is suggested. We analysed the growth changes during two years and final adult height(FAH) in girls with idiopathic CPP treated with combined therapy, compared with those of girls treated with GnRHa alone. Methods : For the analysis, we classified the patients, who was treated for longer than two years, into three groups depending on the initial PAH and combination of GH; PAH_L, treated with GnRHa and PAH less than midparental height(MPH) - 5 cm. PAH_H, treated with GnRHa and PAH greater than MPH - 5 cm. GnRHa+GH, combined GH treatment, regardless of PAH before treatment. We analysed the GV and PAH change during the first two years and FAH. Results : In PAH_L, the PAH(SDS) at first year of therapy was significantly increased to $153.5{\pm}6.5cm(-1.4{\pm}1.3)$ from $149.7{\pm}6.4cm(-2.1{\pm}1.3)$ before treatment(P=0.004). In PAH_H, there was no significant increase in PAH during the two years of treatment. During the first year of combination of GH and GnRHa, GV and PAH increased significantly. We observed significant increases in FAH, comparing to the initial PAH in the PAH_L and GnRHa+GH groups. The height gains(FAH - initial PAH) were significantly higher in the PAH_L and GnRHa+GH groups than that in the PAH_H group. Conclusion : This study suggests the FAH and height gains are improved in patients, whose predicted adult height before treatment was shorter than those with higher predicted adult height, with the treatment of GnRHa alone or in combination with GH. GH could not improve the final adult height, but compensated the growth in patients whose growth velocity was decelerated by GnRHa alone.

  • This report describes three cases of 22q11.2 deletion syndrome (22q11.2DS) diagnosed by array comparative genomic hybridization with final adult height and bone phenotype. The cases involved a 57-year-old woman with hypocalcemic seizure, an 18-year-old man with short stature, and a 24-year-old woman incidentally diagnosed as 22q11.2DS. The first two patients revealed short stature and low bone mineral density, and their deletion sites included the $TBX_1$. The third patient had normal stature and normal bone mineral density, and the deletion site did not include the $TBX_1$. The deletion of specific genes including the $TBX_1$ could be an important factor of skeletal development including height and bone mineral density of 22q11.2DS.

  • Purpose : Short stature is one of the characteristic features of Turner syndrome. We investigated the factors affecting final adult height(FAH) in patients with Turner syndrome. Methods : The study group was comprised of 60 patients who were diagnosed with Turner syndrome by chromosomal study and clinical phenotypes and attained FAH. Data were obtained from retrospective review of the medical records. We analyzed the factors influencing FAH in growth hormone(GH) treated and GH untreated groups. Results : Sixty patients were enrolled; 48 patients received GH treatment, and 12 patients did not. Mean duration of GH treatment was 35.8 months(range 4 to 120 months), and mean dosage of GH was $0.8{\pm}0.2IU/kg/wk$ in GH treated group. Mean growth velocity was $5.6{\pm}2.0cm/yr$, which was significantly higher than that during pretreatment period. In the GH treated group, mean chronological age, bone age, mean height, and height standard deviation(SD) score at GH treatment were $12.2{\pm}2.7yr$ $10.3{\pm}2.5yr$ $127.5{\pm}10.1cm$ and $-3.1{\pm}1.1$, respectively. In the GH treated group, the mean FAH and SD score of FAH were $146.9{\pm}5.8cm$ and $-2.7{\pm}1.2$, respectively, which showed significant differences compared with those of the GH untreated group. Analyzing the factors affecting FAH in GH-treated patients, only the SD score of height at the time of treatment was significantly related to FAH. Conclusion : GH treatment leads to an increment in FAH in patients with Turner syndrome. Average FAH gain was as much as 5.8 cm. SD score of height at the time of GH treatment was the only factor influencing FAH.

  • Purpose : This study compared bone ages measured by the Greulich-Pyle (GP) and Tanner-Whitehouse 3 (TW3) methods and investigated the differences in predicted adult heights measured by Bayley-Pinneau (BP) and TW3 methods. Methods : Bone ages were assessed from left-wrist radiographs by two investigators, one for each GP and TW3 methods in 85 normal children, 30 precocious puberty girls, and 30 constitutional growth delay boys. The differences between the measured predicted adult heights using the BP and TW3 methods were compared in each group. Results : The bone age measured by the TW3 method was less than that by the GP method in normal children. The predicted adult heights measured by the two methods showed no significant difference in normal boys, while the predicted adult height measured by the TW3 method was higher than that by the BP method for normal girls ($156.4{\pm}4.7$ cm vs. $158.9{\pm}3.8$ cm, P<0.01) and for precocious puberty girls ($156.3{\pm}4.0$ cm vs. $159.3{\pm}4.2$ cm, P<0.01). In contrast, the predicted adult height was higher from the BP method than from the TW3 method in constitutional growth delay boys ($173.3{\pm}4.4$ cm vs. $169.7{\pm}3.2$ cm, P<0.01). Conclusion : There were significant differences in predicted adult heights between the BP and TW3 method in normal girls, precocious puberty girls, or constitutional growth delay boys. In precocious puberty and constitutional growth delay, the BP method might be preferred to predict adult height, but further studies on final adult height are needed.

  • For the purpose to develop the pattern of a tailored jacket for the Chinese adult women, a drawing method for the pattern of a tailored jacket was selected with the style of 'on&on', a young and casual brand of Beaucre Merchandising Co., Ltd. that has been successful in the China market, and then the measures to be applied were set up by properly combining the body measures such as the mean, mode and median of the entire group from data measured from women of 18 to 24 years old in Shanghai, China in 2008 and the mean body measures of the body type A of 2008 classified by GB/T 1335.2-1997. The pattern of a tailored jacket developed was verified for feasibility based on a wearing test and then revised for the parts with low jacket ability in general including the bust circumference, waist circumference, hip circumference, shoulder, waist back length and back area. The final measures applied for the development of a tailored jacket were 160-165cm for the height, the bust circumference of 87.7cm, waist circumference of 69.6cm and hip circumference of 92.8cm for a jacket.
