In the paper we address the Distance-Constrained Capacitated Vehicle Routing Problem (DCVRP), where k minimum-cost routes through a central depot have to be constructed so as to cover all customers while satisfying, for each route, both a capacity and a total-distance-travelled limit. Our starting point is the following refinement procedure proposed in 1981(More)
OBJECTIVE To verify the effects of bisphosphonates (Bps) in combination with recombinant human GH (rGH) in pediatric osteogenesis imperfecta (OI) patients; we focused on possible improvement of bone mineral density (BMD), projected bone areas, growth velocity, and fractures risk. DESIGN A randomized controlled 1-year clinical trial on 30 prepubertal(More)
OBJECTIVE TSH resistance ranges from overt nonautoimmune hypothyroidism to subclinical hypothyroidism, defined as mild hyperthyrotrophinaemia but a euthyroid state clinically. To date, 23 inactivating mutations of the TSH receptor (TSHR) gene have been proven responsible for the clinical condition, but an absence of mutations in the TSHR gene has been(More)
In this prospective study, we analyzed 30 male infants with increased neonatal 17-hydroxyprogesterone (17OH-P) (patients) and for comparison 52 age-matched healthy babies (control subjects) with the aim of investigating the hypothalamic-pituitary-testis axis in the first 6 months of life. Although T, FSH, and LH levels were not significantly different in(More)
Obese children have disadvantageous bone geometry, bone of low quality, and reduced strength at non-weight-bearing skeletal sites. The aim of our study was to investigate the role of parathormone (PTH) and the Wnt/β-catenin signaling pathway and its inhibitors, sclerostin and Dickkopf-1 (DKK1), as negative modulators of fat mass on bone. This was a(More)
OBJECTIVE To assess the prevalence of polycystic ovary syndrome (PCOS) in a cohort of young women with previous idiopathic central precocious puberty (ICPP) at least 3 years after menarche, and to look for any predictive factors of PCOS at the time ICPP was diagnosed. DESIGN Longitudinal study. SETTING Pediatrics unit, Verona, Italy. PATIENT(S)(More)
The association between low HDL cholesterol (HDL-C) concentrations and increased cardiovascular risk is well established. Low HDL-C levels were found in subjects with type 1 diabetes (T1D) who presented complications (1) and in untreated subjects with celiac disease (CD). The association between TID and CD might therefore enhance this lipid abnormality and(More)
OBJECTIVE AND IMPORTANCE despite recent progress in imaging, it is still difficult to distinguish between pituitary adenoma and hyperplasia, even using Magnetic Resonance Imaging (MRI) with gadolinium injection. We describe an example of reactive pituitary hyperplasia from primary hypothyroidism that mimicked a pituitary macroadenoma in a child. CLINICAL(More)
The role of CA 15-3 in breast cancer has been widely studied by several authors. This study was designed to describe the predictivity of CA 15-3 determinations for the metastasis or second primary tumor in patients subjected to follow-up for breast cancer. All the 1,123 determinations of CA 15-3 carried out during 1991 in a hospital laboratory were(More)
We report clinical findings, bone mineral density (BMD) and bone biopsy data in ten children with features of classic idiopathic juvenile osteoporosis (IJO). We also screened the patients for mutations in LRP5 and LRP6. We found low BMD in the lumbar spine, the hip and distal radius. In the spine and distal radius, the reduction in BMD was more marked in(More)
