Abstract
BACKGROUND We present results of the development and feasibility testing of CATCH Healthy Smiles, a school-based oral health program, among children in grades K-2 in Houston, Texas. METHODS Study design was cross-sectional (N = 2 schools; N = 125 parent-child dyads; 31 kindergarteners, 42 first graders, and 52 second graders). CATCH Healthy Smiles program was implemented by trained school teachers in the 2016-2017 school year. Trained dentists conducted dental assessments to measure dental caries increment score (d3mfs). Parent-reported 24-hour dietary recalls and surveys assessed child and parent behavioral, environmental, and psychosocial factors. Logistic regression analysis assessed factors associated with caries experience adjusting for covariates. RESULTS Of the 113 children with complete dental assessments, 54% children in grade K, 62% in first grade, and 73% in second grade had caries experience. Children with caries experience had a higher body weight (AdjOR = 1.13, 95% confidence interval [CI]: 1.02-1.29), were less likely to be girls (AdjOR = 0.22, 95% CI: 0.05-0.82), had greater odds of difficulty drinking hot or cold beverages because of dental problems (AdjOR = 13.13, 95% CI: 1.09-275.14), greater frequency of consuming sugar-sweetened beverages (AdjOR = 11.53, 95% CI: 2.10-87.19), greater odds of receiving government assistance (AdjOR = 14.62, 95% CI: 2.74-119.81), and lower odds of seeing a dental provider (AdjOR = 0.11, 95% CI: 0.02-0.45). Process evaluation showed that 100% of the CATCH Healthy Smiles lessons and activities were taught in the two schools with a high degree of program fidelity and acceptability across the schools, children, and parents. CONCLUSIONS These data will be used to conduct a subsequent fully powered cluster randomized controlled trial.

Abstract
PURPOSE To investigate the long-term safety (primary endpoint) and effectiveness (secondary endpoint) of the somatropin biosimilar Omnitrope®. METHODS PATRO Children is an ongoing, multicenter, observational, post-marketing surveillance study. Children who received Omnitrope® for any indication were included. Adverse events (AEs) were evaluated in all study participants. Auxological data, including height standard deviation scores (HSDS) and height velocity standard deviation scores (HVSDS), were used to assess effectiveness. In this snapshot analysis, data from the Italian subpopulation up to August 2017 were reported. RESULTS A total of 291 patients (mean age 10.0 years, 56.0% male) were enrolled at 19 sites in Italy. The mean duration of Omnitrope® treatment was 33.1 ± 21.7 months. There were 48 AEs with a suspected relationship to the study drug (as reported by the investigator) that occurred in 35 (12.0%) patients, most commonly headache, pyrexia, arthralgia, insulin-like growth factor above normal range, abdominal pain, pain in extremity and acute gastroenteritis. There were no confirmed cases of type 1 or type 2 diabetes; however, two patients (0.7%) had impaired glucose tolerance that was considered Omnitrope® related. The mean HSDS increased from - 2.41 ± 0.73 at baseline (n = 238) to - 0.91 ± 0.68 at 6.5 years (n = 10). The mean HVSDS increased from - 1.77 ± 1.38 at baseline (n = 136) to 0.96 ± 1.13 at 6.5 years (n = 10). CONCLUSIONS In this sub-analysis of PATRO Children, Omnitrope® appeared to have acceptable safety and effectiveness in the treatment of in Italian children, which was consistent with the earlier findings from controlled clinical trials.

Abstract
PURPOSE To describe the course of growth hormone response to growth hormone releasing hormone (GHRH) plus arginine provocative test in children with idiopathic short stature (ISS) and to evaluate the role of peak time. METHODS A retrospective study was performed analyzing 344 GHRH plus arginine provocative tests performed in children and adolescents with short stature. Serum GH levels were measured at four-time points (T0', T30', T45' and T60') and GH peak was defined as the maximum value at any time point. Mean (T30'-T60') GH value and area under the curve (AUC) were calculated. RESULTS When analyzing the time of peak at the provocative test, the most frequent peak time was T45' (53.8%) in the ISS group, with no differences in gender, age, and pubertal stage. Analyzing GHD subjects, the most frequent time of peak was T30 (50%). Analyzing the whole population, the GH T0' levels were significantly lower in subjects with the GH peak at T45' than those with the GH peak at T30' (1.7 ± 2.0 vs. 3.2 ± 4.0, p < 0.001). In subjects with GH peak at T45', the value of GH peak, AUC and mean GH were significantly higher than in those with GH peak at T30' and T60'. A direct correlation was found between the value of GH peak and growth velocity SDS (r = 0.127, p = 0.04) and a negative one between GH peak and GH level at T0' (r = - 0.111, p = 0.04), even when adjusted for gender, age, pubertal stage and BMI Z score. CONCLUSIONS The time peak at 45 min seems to be associated with a better response to the test considering GH peak, mean and AUC. Patients with a GH peak at 30 min more probably could have a derangement in GH secretion showing worst growth pattern and/or a GH deficiency and should be carefully observed.

Abstract
In Type 1 Diabetes (T1D) in children, close to the onset the requirements of insulin are often reduced. This represents a transient recovery of endogenous insulin secretion named "honeymoon" because transient and followed by a progressive decline in C-peptide secretion. This case report describes the effect of administration of high dose vitamin D and Ω-3 fatty acids on T1D progression in a 8-year-old child. At today after one year and a half from the onset of T1D, the subject shows a near-normal blood glucose with the administration of 1.5-2 UI of insulin once a day. Thus this report may be of assistance to design additional studies to determine and validate the effect of administration of vitamin D and Ω-3 fatty acids on the progression of T1D.

Abstract
The Fas death receptor triggers lymphocyte apoptosis through an extrinsic and an intrinsic pathway involving caspase-8 and -9 respectively. Inherited defects of Fas function are displayed by a proportion of patients with Type 1 diabetes mellitus (T1DM) especially those with a second autoimmunity (T1DM-p). This study assesses activation of both pathways in Fas-resistant (FasR) patients to localize the defect. 21/28 (75%) T1DM-p, 14/50 (38%) T1DM, and 7/150 (5%) controls were FasR. Analysis of the 35 FasR patients and 20 Fas-sensitive (FasS) controls showed that caspase-9 activity was lower in T1DM-p and T1DM than in controls, whereas caspase-8 activity was lower in T1DM-p than in T1DM and the controls. Single patient analysis showed that 16/35 patients displayed defective activity of one (FasR1), whereas 19 displayed normal activity of both caspases (FasR2) Ages at onset of diabetes mellitus in T1DM and the second autoimmune disease in T1DM-p were lower in FasR than in FasS patients. All FasR1 patients developed diabetes mellitus before the age of 9 years, whereas a later onset was displayed by 26% FasR2 and 53% FasS patients. These data show that defective Fas function may involve both the extrinsic and intrinsic pathway in T1DM and severity correlates with the precocity of the autoimmune attack and its tissue polyreactivity.

Abstract
We previously reported that the combination of two safe proteostasis regulators, cysteamine and epigallocatechin gallate (EGCG), can be used to improve deficient expression of the cystic fibrosis transmembrane conductance regulator (CFTR) in patients homozygous for the CFTR Phe508del mutation. Here we provide the proof-of-concept that this combination treatment restored CFTR function and reduced lung inflammation (P<0.001) in Phe508del/Phe508del or Phe508del/null-Cftr (but not in Cftr-null mice), provided that such mice were autophagy-competent. Primary nasal cells from patients bearing different class II CFTR mutations, either in homozygous or compound heterozygous form, responded to the treatment in vitro. We assessed individual responses to cysteamine plus EGCG in a single-centre, open-label phase-2 trial. The combination treatment decreased sweat chloride from baseline, increased both CFTR protein and function in nasal cells, restored autophagy in such cells, decreased CXCL8 and TNF-α in the sputum, and tended to improve respiratory function. These positive effects were particularly strong in patients carrying Phe508del CFTR mutations in homozygosity or heterozygosity. However, a fraction of patients bearing other CFTR mutations failed to respond to therapy. Importantly, the same patients whose primary nasal brushed cells did not respond to cysteamine plus EGCG in vitro also exhibited deficient therapeutic responses in vivo. Altogether, these results suggest that the combination treatment of cysteamine plus EGCG acts 'on-target' because it can only rescue CFTR function when autophagy is functional (in mice) and improves CFTR function when a rescuable protein is expressed (in mice and men). These results should spur the further clinical development of the combination treatment.

Abstract
AIM We aim to investigate vitamin D (25OHD) levels in children with or without type 1 diabetes (T1D) according to latitude and skin color. METHODS We compared 25OHD levels in children with T1D living in Piedmont, of Caucasian or Moroccan origin, with healthy control subjects matched for age and ethnicity. Data of resident children in Morocco, with and without T1D, were used for comparison. RESULTS Caucasian (21.4±1.5 vs. 24.0±0.5 ng/mL, P<0.05) and Moroccan children with T1D (12.0±2.6 vs. 17.1±1.7 ng/mL, P<0.05) living in Piedmont had lower 25OHD levels than their counterparts without diabetes. Moroccan children living in Morocco with and without T1D had similar 25OHD levels. Vitamin D deficiency was associated with T1D in Caucasian and Moroccan children living in Piedmont (OR: 1.720, CI95% 1.034-2.860, P<0.03), CONCLUSION: Lower vitamin D levels were associated with T1D in Piedmont. Further studies are necessary to explain a possible relationship between vitamin D and T1D.

Abstract
Obesity in childhood is associated with the presence of complications that can undermine health immediately or in the long term. Several conditions, such as pulmonary or orthopedic complications are strictly associated with the severity of overweight, since they are directly associated to the mechanic stress of fat tissue on the airways or on the bones. Other conditions, such as metabolic or liver complications, although increasing with the extent of overweight, are associated with insulin resistance, which can be modulated by different other factors (ethnicity, genetics, fat distribution) and can occur in overweight children as well. No less important are psychological correlates, such as depression and stigma, which can seriously affect the health related quality of life. Pediatric services for the care of childhood obesity need to be able to screen overweight and obese children for the presence of physical and psychological complications, which can be still reversed by weight loss. This article provides pediatricians a comprehensive update on the main complications in obese children and adolescents and their treatment.

Abstract
BACKGROUND Vitamin D exerts pleiotropic effects and few studies are available in the Italian population. AIM Aim of our study was to evaluate vitamin D status in children living in Northern Italy. METHODS We studied vitamin D levels in a population of 113 normal weight (NW) and 444 obese (OB) children, prepubertal and pubertal. We considered vitamin D levels >20 ng/ml as normal, but also measured percentage of children with vitamin D levels higher than a cutoff of 30 ng/ml. RESULTS 68.2 % of NW children showed normal levels of vitamin D, while 31.8 % showed a clear vitamin D deficiency. Only 28.3 % showed vitamin D levels higher than 30 ng/ml. Obese children showed 55.6 % of subjects with normal levels of vitamin D and 44.4 % of subjects a status of vitamin D deficiency. Only the 18.9 % showed vitamin D levels higher than 30 ng/ml. Mean vitamin D levels in NW children (27.3 ± 1.2 ng/ml) were higher than in OB children (21.8 ± 0.6 ng/ml). No differences have been found between prepubertal and pubertal children in terms of vitamin D levels. CONCLUSIONS Our paediatric population demonstrates a low percentage of vitamin D sufficiency. In particular, obese children show only 19 % of subjects with normal levels while almost half of this population shows a clear deficiency. Further studies are needed to support these results and to evaluate the possible metabolic consequences.

Abstract
To assess the incidence of abnormal neuroendocrine function post-traumatic brain injuriy (TBI) in a large group of paediatric patients and its correlations with clinical parameters (Glasgow coma scale-GCS, Glasgow outcome scale-GOS, TC marshall scale, height velocity). We evaluated 70 patients [58 M, 12 F; age at the time of TBI (mean ± SEM) 8.12 ± 4.23 years] previously hospitalized for TBI at the "Regina Margherita" Hospital, in Turin and "Maggiore della Carità Hospital" in Novara, Italy, between 1998 and 2008. All patients included underwent: auxological, clinical, hormonal and biochemical assessments at recall (after at least 1 year from TBI to T0); auxological visit after 6 months (T6) and hormonal assessments at 12 months (T12) in patients with height velocity (HV) below the 25th centile. At T0, 4 cases of hypothalamus-pituitary dysfunction had been diagnosed; At T6 20/70 patients had an HV <25th centile, but no one had HV < the 3rd centile limit. At T12, among the 20 patients with HV <25th centile, in 13 patients the HV was below the 25th centile and GHRH + Arginine test has been performed. Four subjects demonstrated an impaired GH peak and were classified as GH deficiency (GHD). Of these 4 subjects, 3 subjects showed isolated GHD, while one patient showed multiple hypopituitarism presenting also secondary hypocortisolism and hypothyroidism. The GCS at admission and GOS do not correlate with the onset of hypopituitarism. A simple measurement of the height velocity at least 1 year after the TBI, is enough to recognize patients with a pituitary impairment related to GH deficiency. We suggest to follow-up paediatric population who had TBI with auxological evaluations every 6 months, limiting hormonal evaluation in patients with a reduction of height velocity below the 25th centile limit.

Abstract
The craniopharyngioma is a benign intracranial nonglial tumor derived from a malformation of the embryonic tissue. Represents approximately 6-9% of brain tumors in children. It grows close to the optic nerve, hypothalamus and pituitary. The most frequent histological variety in children is adamantinomatous. The initial symptoms of intracranial hypertension is headache and nausea, followed by visual disturbances, impaired hormonal changes such as the secretion of GH, gonadotropins, TSH and ACTH and central diabetes insipidus. We present the clinical case of MD, 5yrs at age, which shows signs of intracranial hypertension syndrome: neuroradiological findings raise the diagnosis of adamantinomatous craniopharyngioma for which the child underwent to sub-total surgical removal of the lesion and radiosurgery treatment. During the disease develops visual impairment, and secondary diabetes insipidus, hypothyroidism hipocotisolism that takes therapy with desmopressin (Minirin), Cortone acetate and L-tiroxine. For the failure of previous therapies, the child has performed chemotherapy with cisplatin (30 mg/sqm/day) and Etoposide (150 mg/mq/day). A year after the end of the last cycle of chemotherapy was detected new progression of the lesion with the appearance of worsening headache and vomiting in the upright position. TC notes the expansion of the third ventricle and the patient undergoes surgery craniotomy. This clinical case underlines the difficulties in treatment of recurrent craniopharyngioma in situations where the anatomical location do not permit aggressive radical surgery. Anyway, new studies are needed to evaluate the effectiveness of systemic chemotherapy as a method of experimental treatment that could reduce the progression of disease.

Abstract
AIM The aim of this paper was to know and analyze information, attitudes and behaviors related with transformations occurring in men when they become fathers. METHODS A self-administered questionnaire has been given out to all men whose newborns were born in the Hospitals located into Borgosesia, Ivrea, Novara, Verbania and Vercelli (Piedmont region in north west of the Italy) in the last quarter of 2006. The questionnaire was created ad hoc and filled out on the day of discharge; results underwent statistical analyses through SPSS system. RESULTS For the duration of the research, out of 870 men who became fathers in the hospitals were involved in this study, 570 responded voluntarily to the self-administered questionnaire (65.6% of the total sample). They showed a lack of information about how to take care of their newborns and the emotional turmoil of women after delivery (58% think children are blind when they are born, 52% think it is better to breastfeed newborns at fixed times and 47% ignore that mothers can enter a depression state). Eighty-eight percent of respondents were in the delivery room to see their child's birth, 56% took a leave from job to stay with mother and child in the hospital and 58% of them report the intention to take an additional 2-3 days leave after coming home from the hospital; 27% had trouble sleeping during pregnancy and are afraid not to be good fathers for their child; 90% believe that their newborn will make them change life habits. Most of the new fathers had difficulties in sharing emotions and feelings related with their status of fathers-to-be with other men. Some of these results are significantly different in older fathers, fathers having their first child and fathers with a lesser level of education. CONCLUSION During pregnancy and in the first months after their child is born, fathers-to-be and new fathers must be considered a potential target for educational interventions aiming at promoting their parenting information and reinforcing their positive attitudes and beliefs related with their fathering status.

Abstract
BACKGROUND TSHR is a G-protein-coupled seven transmembrane domain receptor that activates the two major signal transduction pathways: the Gαs/adenylate cyclase and the Gαq/11/phospholipase C pathways. Inactivating mutations in the TSHR gene have been demonstrated to be responsible for subclinical hypothyroidism, a disorder characterized by elevated serum TSH concentrations despite normal thyroid hormones levels. AIM We identified in a child a nonsense mutation (W520X) in the third transmembrane domain of the TSHR that causes the lack of the C-terminus portion of the receptor. The functional significance of this variation was assessed in vitro. MATERIAL/SUBJECT AND METHODS The W520X mutation was introduced into the pSVL vector containing the wild-type sequence of TSHR gene. Wild-type and mutated vectors were expressed in Chinese Hamster Ovary (CHO) cells, and cAMP, inositol phosphate (IP), immunofluorescence and FACS analyses were performed. RESULTS Transfection with pSVL-TSHR vector induced basal cAMP and IP production in the absence of TSH stimulation, indicating a constitutive activity for the TSHR. An impairment of receptor function was demonstrated by the observation that cells expressing the mutant TSHR exhibited a lower second messenger production with respect to the wild-type, despite a normal expression of the receptor at the cell surface. CONCLUSIONS The mechanism through which the W520X mutation exerts its effect is more likely haploinsufficiency rather than a dominant-negative effect. This could explain the phenotype of our patient, who has a hormonal pattern in the range of a mild subclinical hypothyroidism, without an overt disease phenotype.

Abstract
Patients without spleen or with diminished splenic function are at high risk (10-50 times higher than in normal population) of developing life-threatening infections (OPSI). Mortality from OPSI is estimated at 50 to 80% of cases. More frequent causative agents are encapsulated bacteria: Streptococcus Pneumoniae, Haemophilus influenzae type b and Neisseria Meningitidis. The risk of OPSI can be reduced by immunizing patients against these pathogens and by prescribing antibiotic prophylaxis. Continuous antibiotic prophylactic for 2-5 years after splenectomy (longer periods might expose the patients to the risk of antibiotic resistance) with penicillin or amoxicillin/clavulanate acid is mandatory. Asplenic individuals should take empirical antibiotic therapy - so called "self-treatment" - and immediate medical consultation in presence of febrile illness. All patients and their parents should be carefully educated about the risk of infections in order to obtain a good long-term compliance with these recommendations.

Abstract
BACKGROUND To establish the rate of agreement in predicting metabolic syndrome (MS) in different pediatric classifications using percentiles or fixed cut-offs, as well as exploring the influence of cholesterol. SUBJECTS AND METHODS Cross-sectional study in a tertiary care center. Nine hundred and twenty-three obese children and adolescents were evaluated for metabolic characteristics, cholesterol levels, the agreement rate and prevalence of MS across age subgroups with pediatric National Cholesterol Education Program/ Adult Treatment Panel III (NCEP-ATP III) and International Diabetes Federation (IDF) classifications. RESULTS The overall prevalence of MS was 36.2% and 56.7% with NCEPATP III and IDF. The overall concordance was fair (k: 0.269), with substantial values observed only in children older than 10 (k: 0.708) and 16 yr (0.694). Concordant subjects for both classifications, ≤6 yr, had higher triglycerides, blood pressure (p<0.05) and lower HDL-cholesterol (p<0.0001), with respect to those found to be discordant. Concordant subjects ranging 6-10 yr had all parameters higher than those discordant for IDF (p<0.01) and insulin resistance (p<0.05) than those discordant for NCEP-ATP III. Concordant subjects ≥10 yr presented more altered parameters than those included only in NCEP-ATP III (p<0.05). Overt glucose alterations were uncommon (7.4%; confidence interval 95% 0.1-14.9%), although glucose was modestly higher in MS subjects (p<0.01). Total and LDL-cholesterol was lower in subjects with MS than in those without (p<0.05), and in concordant rather than discordant subjects (p<0.05). CONCLUSIONS Classifications of MS do not identify the same pediatric population. Subjects who satisfied any classification were the most compromised. Lipid alterations were precocious in the youngest. Obese youths with MS presented lower total and LDL-cholesterol.

Abstract
AIM Epistaxis is an extremely common event at all ages; however, under two years of age epistaxis is a very rare event and recent studies carried out in Great Britain concern this event as related to possible non-accidental trauma. To date, no other studies carried out in Italy are available on this topic. METHODS A file review of all cases of epistaxis occurred in children under the age of 2 who were admitted into the ED in our area over a period of two years was carried out. RESULTS We have collected data concerning 10 cases of epistaxis occurred in children under 2 years of age with an incidence of 10.4 cases per 10000 accessions to the ED of children under the age of 2. Four of the cases had attendances for head injury or facial trauma. CONCLUSION The results obtained are higher than the results of the British studies adopting the same methodology, but comparable to their surveillance data on the general population. Through the analysis of the collected data, two correlated assumptions have been made: a possible relationship between epistaxis and neglect, and a relation between epistaxis and domestic accidents.

Abstract
This study was conducted to evaluate the association between pneumococcal DNA load and parapneumonic pleural effusion (PPE) in children with community-acquired pneumonia. Bacterial load was quantified and related to the presence of PPE with or without empyema in 72 otherwise healthy children aged ≤5 years who were hospitalised because of radiographically confirmed CAP and showed a real-time polymerase chain reaction that was positive for Streptococcus pneumoniae. The proportion of children with a high bacterial load (i.e. ≥265 DNA copies/mL) was larger among the subjects with PPE than those without it. Multivariate analysis showed that a high bacterial load was significantly associated with PPE (OR 8.65; 95% CI 1.10-67.8 vs a bacterial load of <125 copies/mL). Children with infection due to pneumococcal serotype 19A were at highest risk of developing PPE (OR 7.44; 95% CI 1.10-50.4 vs all other typeable serotypes). The patients with CAP due to pneumococcal serotypes that are not included in the 13-valent conjugate vaccine (PCV13) were more frequently affected by PPE than those with infections associated with serotypes included in the vaccine, except for serotype 19A. Bacterial loads of ≥265 DNA copies/mL are significantly associated with PPE, and serotype 19A is significantly associated with a high bacterial load and the development of PPE. The mean bacterial load of the patients with empyema was higher than that of patients with simple PPE. Although further studies are required, it seems that serotypes not included in PCV13 can play a major role in causing a higher bacterial load and PPE.

Abstract
An increased prevalence of depression, emotional lability, decreased energy levels, and poor quality of life have been reported in adults with GH deficiency (GHD). The impairment of psychological parameters depends on the aetiology of GHD and the presence of other pituitary hormone deficiencies because of hormonal effects on neural cell metabolism. Cognitive dysfunctions appear to be specifically related to GHD itself, whereas the lower emotional well-being and reduced motor performance are attributed to other pituitary hormone deficiencies. Traumatic Brain Injury causes very often hypopituitarism and GHD as well as other many psychological symptoms: cognitive impairment, sleeping disorders, and depression. Many neurobehavioral symptoms of postconcussion syndrome (PCS) are the same suffered by adult GHD and hypopituitaric patients but there are no data about the occurrence of hypopituitarism in PCS. In some studies treatment with rhGH is reported to have a beneficial effect and GHD could contribute itself to the global impairment of psychological dysfunctions. The link between psychosocial impairments and GHD is not fully understood. The effects of long-term rhGH therapy on cognitive functions are largely unknown. Thus, long-term placebo-controlled double-blind studies are required to investigate whether psychological dysfunctions are reversible on GH substitution.

Abstract
Neisseria meningitidis is a leading cause of bacterial sepsis and meningitis worldwide. Invasive meningococcal disease (IMD) can develop rapidly and is associated with high mortality and morbidity. Case fatality in developed countries averages 10% and higher rates are reported in less prosperous regions. The incidence of invasive disease due to Neisseria meningitidis is highly variable according to geographical area and serogroup distribution. The major disease burden is in developing countries; in industrialized countries meningococcal disease occurs sporadically and most IMD is caused by serogroups B and C. In the US serogroup Y is a major cause of meningococcal disease, accounting for more than one third of cases. Polysaccharide vaccines against serogroups A, C, W-135, and Y were developed but they were not so effective in protecting infants, who are at particularly high risk from invasive meningococcal infections. Conjugation of bacterial capsular polysaccharide to a carrier protein generates a T cell dependent immune response and immunological memory from infancy. After the introduction of serogroup C meningococcal conjugate vaccines since 1999, the incidence of serogroup C disease fell dramatically in countries in which they have been used. The first quadrivalent meningococcal conjugate vaccine (MenACWY-D) was licensed in the US in 2005. More recently, another tetravalent meningococcal conjugate vaccine (MenACWY-CRM, Menveo) was licensed in Europe and the US. Although polysaccharide and glycoconjugate vaccines have been developed for serogroups A, C, Y and W-135, currently there are no broadly effective vaccines available for the prevention of meningococcal B disease.

Abstract
BACKGROUND Ghrelin circulates in blood as acylated (AG) and unacylated (UAG) ghrelin. The physiological role of the two forms is poorly understood, in particular in childhood. Aim of the study was to evaluate the AG and UAG levels in obese and normal weight (NW) children, pre-pubertal and pubertal, and their relationship with insulin, leptin and adiponectin levels. SUBJECTS AND METHODS A population based study in which AG, UAG, leptin, adiponectin, glucose, insulin, testosterone or estradiol levels, insulinemic indexes were evaluated in 82 NW and 58 obese (OB) children. RESULTS Both ghrelin forms in NW were higher (AG, p<0.02; UAG, p<0.0001) than in OB subjects, with similar ratio AG/UAG . While no differences were observed for gender, puberty AG (p<0.01) and UAG (p<0.0001) levels were higher in pre-pubertal than pubertal NW and OB subjects. Adiponectin levels in NW subjects were higher (p<0.001), while leptin and insulin levels were lower (p<0.0001) than in OB subjects. NW children showed homeostasis model assessment (HOMA) and HOMAβ indices lower than OB children (p<0.0001) with a higher a quantitative insulin sensitivity check index (p<0.0001). AG and UAG levels correlated to each other (p<0.0001), each showing a negative correlation to age, height, weight and body mass index. Both forms, but more strongly UAG, correlated with adiponectin, leptin, and insulin. CONCLUSIONS OB children show lower levels of both AG and UAG when compared to NW subjects, with lower levels during puberty. These results demonstrate a peculiar strong relationship between UAG levels and metabolic parameters in the pediatric population, suggesting a role for UAG in metabolic functions.

Abstract
AIM To evaluate if nutritional intakes and lipid profile fulfill international guidelines and recommendations before and after a structured dietician training to a Mediterranean- style diet in an Italian pediatric population with Type 1 diabetes. METHODS A 6-month prospective cohort study. Baseline and after-intervention nutritional intakes, lipid profile, glycated hemoglobin (HbA(1c)), and clinical parameters of 96 children and adolescents with Type 1 diabetes were assessed. A comparative computerized system which was approved and validated by the Italian Diabetologist Association was used to define the amounts of nutrients. RESULTS At baseline mean daily dietary intakes of carbohydrates, proteins, and lipids were respectively (mean ± SEM) 51.8 ± 0.5, 15.9 ± 0.2, 33.8 ± 0.6%, with a contribution of cholesterol of 248.7 ± 12.5 mg/day. Fiber assumption was 18.0 ± 0.4 g/day. The 64.5% and 29.1% (p<0.0001) of subjects had at least one lipid parameter higher than 75(th) and 95(th) percentiles, respectively, of selected cut points (American Diabetes Association guidelines for total and LDL-cholesterol and American Academy of Pediatrics standards for HDL-cholesterol and triglycerides). Six months after the dietician intervention, dietary lipids and cholesterol decreased (p<0.0001) while fibers (p<0.0001) increased. LDL-cholesterol, non-HDL-cholesterol, and total cholesterol:HDL-cholesterol ratios significantly decreased (p<0.001) with a reduction of rate of subjects with at least one pathological lipid parameter (p<0.01) independently by weight and glucose control. CONCLUSIONS Italian pediatric subjects with Type 1 diabetes present a balanced diet with exception of lipids intake and a suboptimal lipid profile. A structured dietician training to a Mediterranean-style diet improves the quality of nutrient intakes being followed by a reduction of LDL-cholesterol, non- HDL-cholesterol, and total cholesterol:HDL-cholesterol ratios.

Abstract
CONTEXT Ghrelin is a peptide with multiple functions that circulates in acylated (AG) and unacylated (UAG) forms. However, the role of ghrelin in neonates (NN) remains to be clarified. OBJECTIVE The aim of this study was to determine ghrelin concentrations of the two forms in NN to clarify their biological roles. As such, ghrelin levels at birth were compared with those in later life. SETTING AND DESIGN Tertiary Care Center. In this cross-sectional study, we evaluated AG, UAG, AG/UAG ratio, and insulin levels in venous cord blood from NN and in fasted normal weight (NW) and obese (OB) children, both prepubertal and pubertal. SUBJECTS We studied 82 NN, 82 NW, and 58 OB children. RESULTS AG levels were lower in NN than in NW and OB children (P<0.0001), more specifically the prepubertal NW and OB children (P<0.0001). UAG levels were higher in NN than in NW and OB children (P<0.0001). Therefore, the AG/UAG ratio was lower in NN than in NW and OB children (P<0.0001). NN showed insulin levels similar to NW and lower than OB children (P<0.0001). At birth UAG was positively correlated with AG (Pearson: 0.425; P<0.0001) and negatively with insulin (-0.253; P<0.02). In NW and OB, UAG and AG were positively correlated to each other and negatively correlated with insulin and body mass index (-0.566; P<0.0001). CONCLUSIONS NN compared with children, showed higher UAG and lower AG levels. The AG/UAG ratio showed a very different profile in NN, being lower than in NW and OB children, thus suggesting a different metabolic function for the two forms in NN. Further studies are needed to clarify the exact role of the different ghrelin forms in NN.

Abstract
The 22q11.2 microdeletion produces many syndromes, characterized by similar phenotypical features. The most known syndromes are: the DiGeorge syndrome, the velocardiofacial syndrome, the conotruncal anomaly face syndrome. The hallmark features are represented by cardiac anomalies, palate defects, immune and cognitive deficiencies, facial dysmorphisms. Less common disorders include: genito-urinary abnormalities, visual defects, autoimmune disorders and pituitary anomalies, being the last represented by growth hormone and/or insulin growth factor-I deficiency. We present the case of a 8 years old male admitted to our Division for failure to thrive. We found growth hormone deficiency and pituitary hypoplasia associated with some of the anomalies shown above, thus we suspected and confirmed the 22q11.2 deletion syndrome. In literature few cases of associated 22q11.2 deletion syndrome with growth hormone deficiency are described, while short stature between children with and children without cleft palate is reported to be more frequent in the first ones, suggesting that the 22q11.2 deletion syndrome remains undetected in many affected children and that the growth hormone deficiency prevalence in affected children has to be investigated. The wide phenotypical presentation of 22q11.2 deletion syndrome requires a multidisciplinary approach to the affected subject and, from the auxologic point of view, is good to monitoring the growing trend and, if short stature is present, check for the growth hormone deficiency.

Abstract
Fabry disease, a rare X-linked lysosomal storage disorder, is caused by deficiency of the enzyme α-galactosidase A. The incidence, ranging from one over 40 000 to one over 11 7000 worldwide is probably underestimated due to its unspecific pattern of presentation. The symptoms, including neurological, gastrointestinal, renal, ophthalmological and dermatologic manifestations, start in childhood and adolescence, cause a significant morbidity and are likely to affect the patient's quality of life. Furthermore, Anderson-Fabry disease always progress leading to a multiorgan dysfunction and life-threatening complications with end-stage renal disease, cardiomyopathy and high incidence of stroke. The estimated life in untreated patients is reduced by 15-20 years respectively in men and women. The enzyme replacement therapy, available in Europe from 2001, results in a reduction of major organs failure, morbidity and mortality. We present the case of an 8-year-old male admitted to our Division for overweight with a previous history of acroparesthesias, severe acute pain in hands and feet, abdominal pain, diarrhoea, constipation, bitemporal headache, dyshidrosis, recurrent fever, exercise intolerance and reduced quality of life. The physical examination was within normal limits. The α-galactosidase A activity was deficient in plasma and normal in peripheral leukocytes; the GLA gene showed a nucleotide substitution c.352C>T (p.Arg 118 Cys) in the eson 2 with a residual enzyme activity of the 29% suggesting the diagnosis of Fabry disease. Blood and urine chemistry, the slit-lamp examination and MRI of kidneys, heart and brain excluded any major organ involvement. The enzyme replacement therapy was then started almost three months ago using agasidase alfa at a dose of 0.2 mg/kg infused intravenously every two weeks but, unfortunately, no relief in the symptoms have been reported so far without any severe adverse reactions. This case report aims to point out the importance of an early diagnosis in order to prevent the progression of the disease, the multiorgan failure and to improve the long-term prognosis.

Abstract
Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder characterized by cafe-au-lait spots, axillary and inguinal freckling, cutaneous neurofibromas with a variable clinical expression, iris Lisch nodules, and multiple tumors, in particular optic nerve and other central nervous system gliomas. About 6% of patients develop hypertension due to renovascular diseases, mid-aortic syndrome, or pheochromocytoma. We present a case of a 8 year old girl with primary diagnosis of NF1suffering of skin and encefalic neurofibromas, inguinal freckling, café-au-lait spots, optic nerve glioma, headache, facial flushing. The 24-h ambulatory blood pressure revealed hypertension without paroximal attacks. Urinary metanephrines, serum aldosteron, renin and kalemia were constantly normal. Magnetic resonance imaging (MRI) and angioMRI excluded stenoses of the renal arteries or adrenal masses. Standard 2D echocardiography was normal. The antihypertensive medication controlled pressure values. We concluded for hypertension due to a low-grade vasculopathy. The periodic monitoring of blood pressure in NF1 patients, accompanied by appropriate diagnostic modalities and physical examination, is essential to precociously diagnose hypertension and avoid life-threatening organ damages and increased mortality.

Abstract
This is the first scientific study on Mary Sandrucci, who has been director of the Pediatric Clinic of the University of Turin from 1965-1966 up to 31 December 1989. Prof. Sandrucci led major studies on congenital heart disease, was the first Italian and among the first in Europe to describe phocomelia cases, to report on valuable studies antibiotics, uric acid, pediatric nephrology, nuclear medicine and genetics. She promoted the development of pediatric specialties, but at the same time promoted the study and practice of paediatrics as a whole. This study describes the past half century of medicine, history of Italian pediatrics and progress of the conquest of rights and equal opportunities for women.

Abstract
Holoprosencephaly (HPE) is a complex brain malformation caused by impaired or incomplete midline division of the prosencephalon. It's characterized by cerebral and facial anomalies of different levels of severity. Both genetic and environmental factors are known to cause HPE, but they cover only few cases. Genetic causes are responsible for about 20% of cases: they are chromosomal abnormalities and gene mutations: up to date, nine genes (SHH, ZIC2, SIX3, TGIF, PATCHED1, TDGF1/CRIPTO, FAST1, GLI2 and DHCR) are definitely associated with HPE, but many others candidate gene are under investigation. The diagnosis of HPE is usually prenatal and is based on systematic ultrasound scan (US) and magnetic resonance imaging (MRI). Children with HPE have many medical problems in agreement with the severity of the brain malformation: craniofacial abnormalities, neurological signs, endocrine disorders, oromotor and dysautonomic dysfunction, thus requiring a multidisciplinary team for symptomatic treatment of manifestations, prevention of complications and parental support. Genetic counselling is an important step, often made difficult by extreme phenotypic variability, genetic heterogeneity, and a high risk of recurrence in apparently sporadic cases. In conclusion it can be concluded that we are far from a complete explanation of the etiopathogenesis. Future researches on genomic rearrangements all over the genome with techniques like the CGH array should lead to the identification of other causal genes and could improve diagnosis and prognosis. A skill multidisciplinary approach is mandatory to offer the better clinical assistance to patients and their parents.

Abstract
AIMS/HYPOTHESIS A shift towards younger age at onset of diabetes in susceptible people has been suggested as a possible explanation for the increasing temporal trend in incidence of type 1 diabetes. We aimed to test this hypothesis by assessing trends in incidence rates in the period 1984-2004 in children and young adults in Northern Italy. METHODS The study bases were: (1) children resident in the Province of Turin in the period 1984-2004 and in the remaining areas of the Piedmont Region in the period 1990-2004; and (2) young adults (15-29 years) resident in the Province of Turin in the period 1984-2003. Temporal trends in rates were analysed using Poisson regression models. RESULTS A total of 1,773 incident cases were identified. Overall incidence rates/100,000 person-years in the age groups 0-14 and 15-29 years were 11.3 (95% CI 10.7-12.0) and 7.1 (95% CI 6.6-7.7), respectively, with sex differences among young adults only (incidence rate ratio [IRR] in males vs females 1.41 [95% CI 1.20-1.64]). Average annual increases in incidence rates were similar in children and young adults at 3.3% (95% CI 2.5-4.1). Compared with the period 1984-89, in 2000-2004 a 60% higher risk was found in both age 0-14 years (IRR 1.60, 95% CI 1.31-1.95) and 15-29 years (IRR 1.57, 95% CI 1.26-1.96) groups. The Poisson modelling showed no interaction between calendar period and age at onset. CONCLUSIONS/INTERPRETATION Incidence of type 1 diabetes in Northern Italy is increasing over time in both children and young adults, not supporting the hypothesis of a shift towards younger age as the main explanation for the increasing temporal trend in children.

Abstract
INTRODUCTION The outcomes of different types of transitions of young people with chronic diseases have been poorly investigated. OBJECTIVE To evaluate and compare a structured transition from the paediatric diabetes services (PDS) into the adult diabetic services (ADS) with an unstructured one. DESIGN We retrospectively investigated 62 adolescents and young adults with type 1 diabetes discharged from the PDS from 1 January 1994 to 31 December 2004. Thirty-two patients (group A) were transferred to the ADS of the same hospital with an unstructured method (letter) and 30 patients after a structured transfer planned with adult physicians (group B). We analysed the date of the first admission in ADS, the glycated haemoglobin (HbA1c), the clinic attendance rate in PDS and in the first year in ADS, and a phone questionnaire on the transition experience. RESULTS The duration of the transfer was longer in A than in B with a lack of medical assistance during the unstructured transition (P < 0.001). At the first visit in ADS, before any medical intervention, HbA1c was improved in B compared to the last in PDS (P < 0.01), and had a trend in worsening in A. After 1 year in the ADS there was a better clinical attendance, and a lower HbA1c in B than in A (P < 0.05). All the subjects of group B reported a favourable opinion for the structured transition (P < 0.0001). CONCLUSION The transition process plays an important role in diabetic care and a structured plan is mandatory to avoid to lose the patients and to get worse their health.

Abstract
BACKGROUND Mutations in the gene encoding the pituitary transcription factor POU1F1 (Pit-1, pituitary transcription factor-1) have been described in combined pituitary hormone deficiency (CPHD). AIM The aim of this study was the characterisation of the molecular defect causing CPHD in a patient born to consanguineous parents. SUBJECT AND METHODS The case of a 12.5-yr-old girl presenting with severe growth failure at diagnosis (-3 SD score at 3 months) and deficiency of GH, PRL, and TSH was investigated for the presence of POU1F1 gene mutations by denaturing high performance liquid chromatography analysis. RESULTS A novel mutation adjacent to the IVS2 splicing acceptor site (IVS2-3insA) was identified in the patient at the homozygous state. Analysis of patient's lymphocyte mRNA and an in vitro splicing assay revealed the presence of 2 aberrant splicing products: a) deletion of the first 71 nucleotides of exon 3, altering the open reading frame and generating a premature stop codon, b) total exon 3 skipping resulting in an in frame deleted mRNA encoding a putative protein lacking part of the transactivation domain and of the POUspecific homeodomain. Notably, the patient's relatives heterozygous for the mutation had PRL levels under the normal range with no evident clinical symptoms. CONCLUSIONS The IVS2- 3insAmutation, responsible for CPHD at the homozygous state, causes the presence of 2 aberrant splicing products encoding non-functional products. In the heterozygotes one normal allele might not guarantee a complete pituitary function.

Abstract
Atherosclerotic cardiovascular disease is a leading cause of morbidity and premature mortality in Western countries and dyslipidemia is a recognized major cardiovascular risk factor. Evidences demonstrate that the atherosclerotic process begins early in childhood. Children showing dyslipidemia, as well as other cardiovascular risk factors, including hypertension, overweight/obesity and diabetes mellitus, are defined at high risk. To identify these children a selective screening between 2 to 10 years of age is necessary. This program must be performed to those children showing a familiarity for primary dyslipidemia and/or precocious cardiovascular events. These subjects need to undergo lipid biochemical analysis and assessment of other emergent risk factors (as ApoB, ApoA-I and their ratio). Given that total cholesterol and low-density lipoprotein cholesterol (LDL-C) concentrations vary by age and sex, the use of percentile values according to these parameters is now recommended. In these high-risk subjects the first step to lower LDL-C under the value of 130 mg/dL is represented by an appropriate physical activities and Step II diet. This entails further reduction of saturated fatty acid intake to less than 7% of daily calories and of cholesterol to less than 200 mg/day (since two years of age). When diet therapy is insufficient to lower LDL-C to the acceptable concentration, the use of non-pharmacologic agents (soluble fibers, plant stanols, sterols) is suggested. The third approach, for children showing persistent elevated LDL-C >95(th) percentile, is represented by drugs, that are allowed only in children older than eight years.

Abstract
Prevalence of childhood overweight and obesity have dramatically increased worldwide in the last decades. Overweight and obesity are the result of a complex interaction between genetic and environmental factors. The aim of our longitudinal study was to assess the prevalence of overweight and obesity in a population of Italian schoolchildren followed for 2 years and to identify main risk factors for obesity onset and persistence in childhood. We enrolled 632 children (males /females= 345/287), aged 3 to 8 yr.Weight and height were measured at time 0, 1 (1 yr later), and 2 (2 yr later). Overweight and obesity were defined using body mass index (BMI) (Italian growth charts). Data collected included: birth weight, gestational age,maternal weight gain during pregnancy, breast feeding, parents' BMI, educational level, and occupation type. At time 0, 1, and 2 the prevalence of overweight was 22%, 22%, and 25%, respectively, and the prevalence of obesity was 7%, 8%, and 8%, respectively. During follow-up 62%of children remained normal weight, 24% was always overweight or obese, 9% became overweight, while only 5% of overweight subjects became normal weight. Male gender, maternal weight gain during pregnancy >10 kg, parental overweight/obesity were positively associated with the presence of overweight during the entire follow-up. On the contrary, being small for gestational age at birth was negatively related to persistence of overweight. No influence was found for being breastfed, for parental low educational level, and manual occupation. A large prevalence of overweight/obesity was observed in Italian schoolchildren. Gender, maternal weight gain during pregnancy, and parents' BMI were the strongest predictors of the persistence of child overweight and obesity.

Abstract
Isolated GH deficiency or combined pituitary hormone deficiencies have been associated with mutations in transcription factors encoding genes that control organogenesis or cell differentiation. Among these factors, Hesx1 is essential for the development of the optic nerve and regulates some of the earliest stages in pituitary development and is intimately involved in orchestrating the expression of other factors involved in pituitary organogenesis. Mutations in HESX1 are reported in patients with hypopituitarism either with typical septo-optic dysplasia (SOD) or with neuromorphological abnormalities not included in classical SOD. The present report describes clinical features, biochemical parameters, and characterization of a missense mutation (Gln6His) in exon1 of HESX1 in a pre-pubertal child who progressively developed multiple hypopituitarism, firstly GH and, afterwards, TSH and ACTH deficiencies, in a pluri-malformative syndrome characterized by short stature and anatomical malformations not associated with a classical SOD phenotype. This finding further supports the necessity to stay alert in evaluating a gene that plays a minor role in the pathogenesis of sporadic hypopituitarism, such as HESX1 gene even when the phenotype does not fit in with a classical SOD syndrome.

Abstract
AIM Inhaled corticosteroids (ICS), for years used in the therapy of low-moderate bronchial asthma, reduce the rate of asthmatic attack with improved pulmonary functioning and quality of life. Clinical trials have been addressed mainly to study the efficacy rather than the safety of drugs, so that the side effects of these drugs have not yet been accurately defined. Clinical experience shows that growth delay appears in the first months of therapy with ICS. The aim of the study was to evaluate the influence of the therapy with spacer-administered inhaled corticosteroid on short-term auxological development in prepubertal children. METHODS In a group of children with low asthma, height and weight have been evaluated before and after six months of inhaled therapy with dipropionate fluticasone at a dose of 100 microg per day. RESULTS Twenty-five patients (19 males and 6 females; age 5.5+/-1.6 years; range: 2.6-7.8 years) showed a regular growth during the six months of therapy (mean height 0.8 standard deviation score [SDS] before therapy and 0.8 SDS after therapy), while 21 (17 males and 4 females; age 10.0+/-1.5 years; range 8.0-12.7 years) showed an increment of growth rate (mean height from 0.5 SDS to 0.7 SDS, respectively). CONCLUSION Spacer-administered low dose fluticasone does not negatively influence short-term growth rate, regardless of the age of the patients.

Abstract
Acylated ghrelin has been originally described for its potent GH-releasing activity mediated by the activation of the GH secretagogue receptor type 1a. More recently, ghrelin has been reported to exert several other GH-independent biological actions, among which in the modulation of metabolic functions. Glucocorticoids are well known to exert important metabolic functions but also to modulate GH secretion, although through mechanisms that have not been fully clarified so far. Interestingly, the existence of a feedback link between glucocorticoids and ghrelin system has already been reported. The aim of our study was to evaluate the acute GH and ghrelin responses to dexamethasone (DEX) administration in children with idiopathic short stature (ISS) or isolated idiopathic GH deficiency (GHD). Eight children with ISS (age: 9.5+/-1.2 yr) and 7 with GHD (12.1+/-1.4 yr) underwent iv DEX administration (0.3 mg/body surface area at 0 min). IGF-I, GH, and ghrelin levels were assayed at baseline and every 30 min from 120 up to 240 min after DEX. Compared to baseline levels DEX decreased ghrelin in ISS at 120 min and 240 min (p<0.04). On the other hand DEX did not modify ghrelin levels in GHD. After DEX, ghrelin was reduced in ISS compared to GHD (p<0.02). DEX increased GH in ISS but not in GHD (peak: 11.1+/-1.2 vs 7.6+/-0.9 microg/l). Basal, as well as after-DEX ghrelin levels negatively correlated with IGF-I in GHD (p<0.03) and with height SD score (HSDS) in ISS (p<0.02). Acute DEX administration is able to decrease ghrelin in ISS, but not in GHD children. Both basal and after-DEX ghrelin levels negatively correlate with IGF-I and HSDS. All these data suggest the existence of a feedback link among ghrelin, glucocorticoids and the GH/IGF-I axis.

Abstract
Germinoma represents 7.8% of cerebral tumors in pediatric age and 50-65% of germ cell cerebral tumors. Generally it is a definite lesion of the pineal gland or suprasellar region, frequently occurring in the first three decades of life. Clinical presentation depends on tumor localization. Pineal lesions generally determine symptoms due to the compression of cerebral structures, causing Parinaud syndrome, while hypothalamic lesions are often characterized by diabetes insipidus, hypopituitarism and visual defects. In the absence of these classic signs and symptoms, however, the diagnosis of germinoma can be difficult. We presented the case of an 8-year-old boy, referred to our clinic for polyuria and polydipsia. Hormonal evaluations demonstrated central diabetes insipidus (CDI), with normal anterior pituitary function. Magnetic resonance imaging (MRI) showed a lack of posterior pituitary gland and partial pituitary stalk enlargement. The patient started therapy with desmopressin (Minirin) with good hydro-electrolytic balance. During follow-up the pituitary function became insufficient with low growth velocity. A second MRI demonstrated a bifocal lesion with dyshomogeneous and cystic appearance, suggesting the diagnosis of germinoma. On the basis of this case report we would like to point out the importance of an early diagnosis in order to improve the prognosis of the disease and the necessity of a careful follow-up of these patients.

Abstract
Polyuria and polydipsia could be present in three groups of diseases; polydipsia psicogena characterized by an excessive water intake, central diabetes insipidus (CDI) with a defect in the production of AVP and nephrogenic diabetes insipidus in which a defect in the renal response to vasopressin is present. In particular, CDI can be caused by lesions like germinoma and craniopharyngioma, Langerhans'cell histiocytosis, inflammatory, autoimmune and vascular diseases, trauma resulting from surgery or an accident; and in rare cases, genetic defects in the synthesis of vasopressin that are inherited as autosomal dominant or X-linked recessive traits. However, 30% to 50% of cases are considered idiopathic. Nevertheless, 30-50% of cases is considered idiopathic. Here we present the case of a 5.5 year-old female patient, referred to our Department of Endocrinology Surgery for polyuria and polydipsia. Hormonal tests demonstrated the presence of CDI with normal anterior pituitary function. Magnetic resonance imaging showed the lack of hyperintensity of posterior pituitary. Pituitary stalk was median and of regular volume. Diagnosis of CDI has been confirmed and therapy has been started with desmopressin (Minirin) 0.2 mg/die. During the follow-up the patient was in good conditions, presented an adequate hydro-electrolytic balance and normal growth velocity. Anterior pituitary function was normal and MR remained stable. This case report highlights problems concerning differential diagnosis and the importance of a careful follow-up which must involve the whole family.

Abstract
In this analysis of hematopoiesis, the regrowth of colony-forming cells in the bone marrow was examined in patients who had undergone medullary ablation and bone marrow transplant. The various stages of erythropoeisis and the factors that influence blood cell production are discussed: hematopoietic microenvironment, cytokines, tissue oxygen. Drawing on results from rodent and human studies, growth hormone factor (GH) function is explained, its interaction with insulin-like growth factors I and II (IGF I and II), and their effects on hematopoiesis. The aim of the study was to show the close link between GH, IGF I and II and erythropoiesis, because patients with GH deficit may present with partially impaired erythyroid proliferation that leads to the onset of anemia.

Abstract
Children born small for gestational age may demonstrate continued growth retardation, resulting in persistent short stature. In the majority of the cases, this is linked with abnormal growth hormone secretion and also abnormal insulin-like growth factor levels. This review discusses the treatment of such children with recombinant human growth hormone. It illustrates the importance of starting therapy early, the dose-dependent response, and the advantages of continuous therapy and describes safety considerations.
