Objective. To explore the clinical effect of auxiliary comprehensive management combined with growth patch in the treatment of childhood idiopathic short stature (ISS). Methods. From September 2017 to December 2019, 120 children with ISS who met the selection criteria were collected. Random number table method divided them into 2 groups: one group was given auxiliary comprehensive management and recorded as the routine group (n = 60), and the other group was given auxiliary comprehensive management and combined growth patch treatment and recorded as the combination group (n = 60). The course of treatment was 12 months. The effects of the two methods on children’s height, bone age, body weight, and insulin-like growth factor (IGF)-1 and IGF-binding protein (IGFBP)-3 levels were compared. Results. There was no statistical difference between the two groups in baseline height, genetic height, baseline bone age, baseline body weight, and body weight before and after treatment ( P > 0.05 ). After treatment, the heights of the two groups were higher than before for the same group, the height growth values and predicted adult height of the combination group were higher than those of the routine group, and the predicted adult height of the combination group was higher than the genetic height of the same group P < 0.001 . There was no statistical difference in IGF-1 and IGFBP-3 levels before treatment between the two groups ( P > 0.05 ). The levels of IGF-1 and IGFBP-3 after treatment in the two groups were higher than those in the same group before treatment, and the combination group was higher than that in the routine group ( P < 0.05 ). Conclusion. On the basis of auxiliary comprehensive management, combined with growth patch for the treatment of children with ISS, it can effectively increase the height of the children, improve the levels of serum IGF-1 and IGFBP-3, and have significant clinical effects, which is beneficial to the healthy growth of the children.

Background: Dexmedetomidine is a highly selective α2-adrenoreceptor agonist that produces dose-dependent sedation, anxiolysis, and analgesia without respiratory depression. Due to these ideal sedative properties, there has been increased interest in utilizing dexmedetomidine as a first-line sedative for critically ill patients requiring light sedation. Objective: To evaluate the ability to achieve goal intensive care unit (ICU) sedation before and after an institutional change of dosing from actual (ABW) to adjusted (AdjBW) body weight in obese patients on dexmedetomidine. Methods: This study included patients ≥ 18 years old, admitted to a surgical or medical ICU, required dexmedetomidine for at least 8 hours as a single continuous infusion sedative, and weighed ≥ 120% of ideal body weight. Percentage of RASS measurements within goal range (−1 to +1) during the first 48 hours after initiation of dexmedetomidine as the sole sedative agent or until discontinuation dosed on ABW compared to AdjBW was evaluated. Results: 100 patients were included in the ABW cohort and 100 in the AdjBW cohort. The median dosing weight was significantly higher in the ABW group (95.9 [78.9-119.5] vs 82.2 [72.1-89.8] kg; p = 0.001). There was no statistical difference in percent of RASS measurements in goal range (61.5% vs 69.6%, p = 0.267) in patients that received dexmedetomidine dosed based on ABW versus AdjBW. Conclusion: Dosing dexmedetomidine using AdjBW in obese critically ill patients for ongoing ICU sedation resulted in no statistical difference in the percent of RASS measurements within goal when compared to ABW dosing. Further studies are warranted.

OBJECTIVES: In the majority of children with short stature, the etiology is unknown. Mutations of the GH receptor (GHR) have been reported in a few children with apparent idiopathic short stature (ISS). These patients had low IGF-I, IGF-binding protein-3 (IGFBP-3) and GH-binding protein (GHBP), but a normal or exaggerated GH response to provocative stimuli, suggestive of partial GH insensitivity (GHI). We attempted to identify children with partial GHI syndrome, based on their response to GH provocative stimuli and other parameters of the GH-IGF-I axis. SUBJECTS AND METHODS: One hundred and sixty-four pre-pubertal children (97 boys, 67 girls) aged 7.2 (0.5-16.75) years were studied. All had short stature with height <3rd centile. The weight, bone age (BA) and body mass index (BMI) of the subjects, as well as the parents' heights and mid parental height (MPH) were assessed. Basal blood samples were taken for IGF-I, IGFBP-3 and GHBP. All subjects underwent a GH provocative test with either clonidine, arginine or insulin. The subjects were divided into three groups: (A) patients with peak GH concentration <18 mIU/l in two different provocative tests (GH deficiency - GHD, n=33); (B) patients with peak GH between 18.2 and 39.8 mIU/l (normal response, n=78); (C) patients with peak GH >40 mIU/l (exaggerated GH response, n=53). RESULTS: No significant differences were found in age, height (standard deviation score (SDS)), parental height (SDS) and the difference between chronological age and bone age (DeltaBA) between the groups. Patients with GHD were heavier (P=0.039) and had significantly higher BMI (SDS) (P=0.001) than the other groups. MPH (SDS) was lower in the group of exaggerated responders (P=0.04) compared with the other groups. No significant differences were found between the groups for the biochemical parameters when expressed nominally or in SDS, except for IGFBP-3 (SDS), which was lower in the GHD group (P=0.005). The GHBP levels were not lower in the group of exaggerated GH response to provocative stimuli. Height (SDS) correlated negatively with basal GH values in pooled data of all the subjects (r=-0.358, P<0.0001), in normal responders (r=-0.45, P<0.0001) and in the exaggerated responders (r=-0.341, P<0.0001), but not in the GHD group. CONCLUSION: Exaggerated GH response to provocative tests alone does not appear to be useful in identifying children with GHI.

Abstract Anthropometry and vertebral abnormality in Children with Transfusion-dependent Thalassemia in Phramongkutklao HospitalBackgrounds: Thalassemia is an untreatable inherited hematologic disorder, unless stem cell transplantation, characterized by anemia from decreased hemoglobin production. Growth failure is one of the most common endocrine dysfunction in children with transfusion-dependent thalassemia (TDT) Objective: To evaluate the prevalence and associated factors of anthropometry and vertebral abnormality in transfusion-dependent thalassemia (TDT) children in a single tertiary center. Method: A cross-sectional study was conducted in transfusion dependent thalassemia patients who had visited in pediatric hematology clinic during 1st January 2018 to 31st December 2019. Collaborators had examined by history taking, physical examinations, laboratory and radiology reviewed. Results: Eighty-one collaborators were enrolled. Mean age was 13.7 ± 6.4 years and 46 of them (56.8%) were male. Pre-transfusion Hb and serum ferritin were 8.0 ± 1.0 g/dL and 1,562 + 1,394 ng/mL, respectively. Twenty-one (25.9%) had short stature determined by predicted adult height (PAH) below target adult height (TAH), 27(33.3%) had decreased upper-lower segment ratio for and 21 (26%) had BMI z-score below -2SD for age. Delay puberty was found in 13.2% of patients. Radiological examinations revealed delayed bone age of 4.9% and osteopenia of 25.9% whereas no vertebral fracture was documented. In multivariate logistic regression analysis (backward Wald), Serum ALP (p=0.009), mean pre-transfusion hemoglobin &lt;9 g/dL (p&lt;0.001), osteopenia (p=0.05) and delay bone age (p=0.019) were associated with PAH below TAH. Duration of chelation (p=0.013) and osteopenia (p=0.015) were associated with decreased upper-lower segment ratio. Low serum calcium (p=0.009), high serum phosphate (p=0.04) and impaired fasting glucose (p=0.004) were associated with BMI z-score below -2SD for age. Conclusions: Anthropometry abnormalities, including short stature, abnormal upper-lower segment ratio and low BMI, are common in TDT children. However, no vertebral abnormality was found in this study. Routine screening program by multidisciplinary team approach should be applied in thalassemia children.Keywords: Thalassemia major, endocrinopathies, growth failure, short stature, body disproportion

OBJECTIVE: Children with shunted hydrocephalus experience slow linear growth in prepuberty, accelerated pubertal maturation and a reduced final height. A substantial proportion of these patients have a poor growth hormone (GH) response to stimulation and reduced pituitary volume. The basic mechanisms behind these phenomena are still unknown, but one can hypothesize that an unphysiological intracranial pressure (ICP) may be involved. This study was undertaken to investigate the effect of increased ICP on pituitary function. DESIGN: Twenty-one children (nine males) aged 4 months to 15 years were evaluated for pituitary function before and after their first shunting operation. METHODS: A clinical examination was performed, bone age was determined and a combined pituitary stimulation test was performed to evaluate GH, luteinizing hormone, follicle-stimulating hormone, cortisol, thyrotropin and prolactin secretion. RESULTS: GH concentrations were significantly higher 10 and 15 min before the operation (P=0.04 and P=0.03 respectively) than after it. The basal levels of insulin-like growth factor-I (IGF-I) tended to be higher before the operation than afterwards and those of its binding protein-3 (IGFBP-3) were significantly so (P<0.01). CONCLUSIONS: The higher GH response to GH releasing hormone and circulating IGFBP-3 levels in children with hydrocephalus before compared with after their first shunting operation raise the possibility that the reduced GH secretion and retarded linear growth observed in children with shunted hydrocephalus may be a consequence of decreased ICP and/or the lack of physiological pressure variations.

Background. Data on adult height outcomes of the use of Anastrozole and Growth Hormone (GH) in pubertal males with Growth hormone deficiency (GHD) and Idiopathic short stature (ISS) are limited. Objective. We examined the effect of Anastrozole and GH therapy on near adult height (NAH) with pubertal males with GHD or ISS. Methods. Retrospective review of 419 charts from 2008 to 2015. The primary outcomes are NAH compared to mid-parental target height (MPTH) and predicted adult height (PAH). Results. We identified 23 patients (5 SGA/IUGR, 1 Noonan syndrome, 6 GHD, and 11 ISS). Six patients (4 GHD; 2 ISS) achieved NAH. Prior to Anastrozole treatment, the mean chronological age was 13.9±0.2 years (range 13.7–14.4), bone age was 13.6±0.6 years (range 12.5–14), mean height SDS was -1.5±0.5 (range −0.8 to −2.3), and mean PAH was 162.6±5.9 cm (range 153.5–168.6). MPTH was 173.6 cm ± 7 (range 161.8–181.6). Patients received Anastrozole for an average of 30.5 months (range 19–36 months). At NAH, the mean chronological age was 16.7±0.8 years (range 15.9–18.1 years) and height was 170±1.8 cm (range 168.5–173.4 cm). The mean height SDS improved to +0.81±0.6 (range +0.08 to +1.92, p=0.002). Net height gain was 7.3 cm compared to pretreatment PAH (p<0.01) and overall the mean adult height remained 3.5 cm below MPTH. Conclusion. Anastrozole and GH therapy can be effective in augmenting adult height without significant side effects. However, the long-term safety and efficacy of aromatase inhibitor use in pediatrics remain limited.

Abstract Context: There is no consensus on the effect of recombinant human growth hormone (rhGH) therapy on skeletal maturation in children despite the current practice of annual monitoring of skeletal maturation with bone age in children on rhGH therapy. Aims: To investigate the effects of long-term rhGH therapy on skeletal age in children and explore the accuracy of bone age predicted adult height (BAPAH) at different ages based on 13 years of longitudinal data. Methods: A retrospective longitudinal study of 71 subjects aged 2-18 years, mean 9.9 ± 3.8y, treated with rhGH for non-syndromic short stature for a duration of 2-14y, mean, 5.5 ± 2.6y. Subjects with syndromic short stature and systemic illnesses such as renal failure were excluded. Results: Bone age minus chronological age (BA-CA) did not differ significantly between baseline and the end of rhGH therapy (-1.05 ± 1.42 vs -0.69 ± 1.63, p=0.09). Piece-wise regression however showed a quantifiable catch-up phenomenon in BA of 1.6 months per year of rhGH therapy in the first 6.5y, 95%CI 0.023 - 0.229, p=0.017, that plateaued thereafter, β=0.015, 95% CI -0.191-0.221, p=0.88. There was no relationship between BAPAH z score – height z score and the duration of rhGH therapy, p=0.68. BAPAH overestimated final adult height in younger subjects but became more precise in older subjects (p&lt;0.0001). Conclusion: Long-term rhGH therapy demonstrated an initial catch-up phenomenon in skeletal maturation in the first 6.5y that plateaued thereafter with no overall significant advancement in bone age. These findings are reassuring and do not support the practice of yearly monitoring of skeletal maturation with bone age in children on rhGH therapy, especially in younger subjects where BAPAH is imprecise.

Abstract BackgroundThe growth potential of pubertal short stature boys is limited by the effect of estrogen on epiphyseal fusion. This study aims to identify the efficacy and safety of growth hormone (GH) combination with letrozole on final adult height (FAH) in pubertal short stature boys. MethodsThis is a retrospective study. Among pubertal short stature boys who treated with GH and letrozole were be followed up in our hospital, 20 cases reached FAH. ResultsBaseline chronological age were 12.12±1.14yr, bone age were 13.00±0.93yr. The treatment duration was 1.94±0.67yr. The height standard deviation score for bone age was increased from -1.46±0.51 to -0.12±0.57 (p<0.000). The predicted FAH before treatment, predicted FAH after treatment, FAH, and genetic target height were 161.02 ±4.12 cm, 172.11±4.20 cm, 172.67±2.72cm and 167.67±3.56 cm, respectively. There was significant differences between predicted FAH before treatment and after treatment (p<0.000), as well as predicted FAH before treatment and genetic target height (p<0.000).The predicted FAH after treatment was higher than that of genetic target height (p<0.001), as well as FAH and genetic target height (p<0.000). ConclusionsThe GH combination with letrozole can enhance the FAH in pubertal short stature boys. No significant side effects were observed.

Objective. To explore the effect of acupoint application of Chinese medicine on children’s height and bone age. Methods. Altogether, 120 children with a short stature treated in our hospital from September 2017 to September 2018 were divided into the control group (CG, n = 60) and the observation group (OG, n = 60) according to the random number table method. The children in CG were given healthy diet and exercise plans and supplemented with daily vitamin intake. The OG was treated with acupoint application of Chinese medicine on the basis of the CG. The clinical efficacy of the CG and the OG of children after treatment was observed. The height increment, growth rate, and bone age of children were compared before and after treatment. The levels of IGF-1 and 25-(OH)D in the serum of children before and after treatment were tested. According to the clinical curative effect after treatment, the children were divided into good curative effect group (markedly effective + effective) and poor curative effect group (ineffective). Logistics regression analysis was applied to analyze the risk factors. Results. Compared with the CG, the curative effect on the OG was evidently improved ( P < 0.05 ). In addition, the height increment, the growth speed, and the bone age of the OG increased evidently ( P < 0.05 ). Compared with the CG, the expression of IGF-1 and 25-(OH)D of the OG elevated ( P < 0.05 ). Serum IGF-1 and 25-(OH)D concentrations were positively correlated with growth rate and bone age ( P < 0.05 ). Risk factors analysis showed that disease course, IGF-1, 25-(OH)D expression, and heredity were the risk factors affecting the curative effect on children. Conclusion. Acupoint application of Chinese medicine has effect on the height and bone age of children with short stature, which is worthy of clinical promotion. In addition, early treatment should be carried out to improve the clinical efficacy of children.

Growth hormone-releasing peptide (GHRP)-2 is a synthetic six amino acid peptide that is a potent GH secretagogue. Although it shares no structural homology with GH-releasing hormone, in clinical studies its actions on the pituitary release of GH are similar. It is effective when administered orally and intranasally. For children with GH deficiency, such noninvasive treatments are most desirable and in need of development. Fifteen children with short stature participated in this study. All of the children had a height < 2 S.D. below mean for age, poor height velocity, delayed bone age, and low serum concentrations of IGF-1. These children had been tested with standard GH secretagogues, e.g. arginine, insulin, and L-dopa. Fifty percent of the children were GH deficient, the remainder had idiopathic short stature. The children received testing with GHRH and GHRP-2 as an acute i.v. bolus of 1 microgram/kg; all children in this study demonstrated a GH response > 20 micrograms/l. Each child in this study also demonstrated a GH response > 10 micrograms/l in response to intranasal GHRP-2, in the dose range of 5-20 micrograms/kg. The children were administered intranasal GHRP-2, 5-15 micrograms/kg, twice a day for 3 months, then three times a day. Fifteen children participated in the study for 6 months; six of the children have participated for 18-24 months. Height velocity, serum IGF-1, IGF-binding protein 3 (IGFBP-3) and GH-binding protein (GHBP) concentrations, and GH responses to GHRP-2 by i.v. bolus and intranasal spray were examined during treatment. Height velocity increased from 3.7 +/- 0.2 cm/year to 6.1 +/- 0.3 cm/year at 6 months, 6.0 +/- 0.4 cm/year at 18-24 months. There were no significant changes in IGF-1 or IGF-PB3 concentrations, or in acute GH responses to i.v. or intranasal GHRP-2. GHBP concentrations rose significantly, from 439 +/- 63 pmol/l to 688 +/- 48 pmol/l. In this study, intranasal GHRP-2 administration was well tolerated, and produced a modest but significant increase in growth velocity.
