Comparison between euglycemic hyperinsulinemic clamp and surrogate indices of insulin sensitivity in children with growth hormone deficiency

2018

Objective: Data about the impact of growth hormone treatment (GHT) on insulin sensitivity in children are quite controversial, due to the different surrogate indices that have been used. Design: We evaluated insulin sensitivity through the euglycemic hyperinsulinemic clamp, considered the gold standard technique, in 23 children affected by growth hormone deficiency (GHD) at baseline and after 12. months of GHT and in 12 controls with short stature at baseline, and we compared the clamp-derived index (M-value) with the most commonly used surrogate index of insulin sensitivity, as ISI Matsuda, and with circulating plasma markers of insulin sensitivity, as adiponectin and resistin levels. Resu…

Chronic idiopathic hyperphosphatasia with unusual dental findings: a case report

2012

Chronic idiopathic hyperphosphatasia(CIH) or juvenile Paget disease is believed to be a distinct disease characterized by an increase in the serum alkaline phosphatase, cortical thickening and bowing of the long bones, especially the femora. It is a rare autosomal recessive bone disorder, with excessive bone resorption and bone formation. Skeletal malformations in the legs may cause problems in walking and may eventually result in short stature. The radiographic appearances include widening of the diaphyses, vertebral osteoporosis, acetabular protrusion, and thickening of the skull vault. Intensive bisphosphonate treatment prevented the development of deformity and disability but there is n…

Estudios clínicos sobre la enfermedad celíaca (2014-2019): revisión sistemática de la prevalencia de la presentación clínica y enfermedades asociadas…

2020

Introducción: La enfermedad celíaca (EC) se caracteriza por una gran variedad de signos, síntomas y enfermedades asociadas en su forma de presentación, incluso puede cursar de forma asintomática. Recientes estudios muestran la variación del espectro clínico según la edad. En niños y niñas pequeñas predomina la forma clásica con síntomas como distensión abdominal, disminución del apetito, diarrea y pérdida de peso. Las manifestaciones atípicas frecuentes en niños mayores son dolor abdominal, estreñimiento, reflujo, vómitos, fatiga, talla baja. En adultos se observa una reducción de la forma de presentación clásica e incremento de la no clásica.Material y métodos: Se realizó una revisión sist…

PIK3R1 Mutations Cause Syndromic Insulin Resistance with Lipoatrophy

2013

International audience; Short stature, hyperextensibility of joints and/or inguinal hernia, ocular depression, Rieger anomaly, and teething delay (SHORT) syndrome is a developmental disorder with an unknown genetic cause and hallmarks that include insulin resistance and lack of subcutaneous fat. We ascertained two unrelated individuals with SHORT syndrome, hypothesized that the observed phenotype was most likely due to de novo mutations in the same gene, and performed whole-exome sequencing in the two probands and their unaffected parents. We then confirmed our initial observations in four other subjects with SHORT syndrome from three families, as well as 14 unrelated subjects presenting wi…

GH successful treatment in a female with a de novo 46,XX,add(X)(p36),t(X;Y)(p36.3;p11.2), growth impairment and SHOX-haploinsufficiency

2019

Abstract Children with chromosome translocations, concerning X chromosome, have a genetic pattern different from Turner syndrome; however, when a translocation involves the of part of X chromosome including short stature homeobox-containing Sex-determining Region Y gene, growth may be severely compromised. We describe the clinical case of a 2.2-year-old-female, arrived at our paediatric unit for a decrease of height velocity. The karyotype was 46,XX,add(X)(p36.3). Array comparative genomic hybridization showed a fragment of Y chromosome, extended from 8.803.981 (Yp11.2) to 28.767.604 (Yq11.23). The final karyotype was 46,XX,add(X)(p36),t(X;Y)(p36.3;p11.2). Fluorescence in situ Hybridization…

SHOX HAPLOINSUFFICIENCY INTRA FAMILIAL PHENOTIPIC VARIABILITY AND THE IMPACT ON FINAL HEIGHT: REPORT OF A PEDIGREE

2019

SHOX haploinsufficiency (SHOX-D) is a genetic cause of disharmonic short stature. However, the different impact on phenotype can show differences between patients with the same genotype. GH ameliorates final height, with significant differences between patients for the putative role of environmental factors who can influence growth.

A girl with inverted triplication of chromosome 3q25.3 → q29 and multiple congenital anomalies consistent with 3q duplication syndrome

2005

We report a newborn girl with intrachromosomal triplication of 3q25.3 --> q29 (mosaicism) who died at the age of 3.5 weeks due to her malformations. She demonstrated disproportionate short stature with short limbs, a prominent and hairy forehead, thick eyebrows, synophrys, small upturned nose, full cheeks, micrognathia, and low set malformed and posteriorly rotated ears, short and webbed neck, hydrocephalus, Dandy-Walker malformation, spina bifida, complex heart defect (ventricular and atrial septal defect, malrotation, and interrupted aortic arch), omphalocele, polycystic kidneys, postaxial polydactyly of left hand, and generalized hirsutism; all signs have been associated with the dup(3q)…

Simultaneous stimulation of growth hormone, adrenocorticotropin and cortisol with L‐dopa/L‐carbidopa and propranolol in children of short stature

2000

In 59 otherwise healthy children of short stature, the simultaneous response of growth hormone, cortisol and plasma adrenocorticotropin (ACTH) to L-dopa/L-carbidopa and propranolol at 45 and 90 min after administration were investigated. A growth hormone response of 10 microg/l or higher was considered positive. The definition of a positive cortisol response included either a hormone increase of at least 193 nmol/l or a peak hormone level of at least 497 nmol/l. The ACTH increase had to be fourfold above 11 pmol/l to be considered positive. In the 59 investigated children, the median basal growth hormone levels increased from 1.35 microg/l to 18.05 microg/l and 10.15 microg/l at 45 and 90 m…

The effect of nacom (L-dopa and L-carbidopa) on growth hormone secretion in 75 patients with short stature.

1977

The stimulatory effect of Nacom (250 mg L-Dopa and 25 mg L-Carbidopa) on the HGH secretion was evaluated in 75 short stature patients. The number of blood samples was restricted to only three (0, 45 and 90 min). 63 patients reached adequate HGH concentrations after the ingestion of 1 tablet Nacom (84%). Somatotropin levels increased from 2.08 (Sx 0.28) to a maximal HGH value of 14.22 (Sx 0.87) ng/ml. When the stimulatory effect of Nacom was compared with the standard method of arginine infusion in children with normal stature the arginine test was not superior to the Nacom-test. The Nacom-test appears to be a simple and reliable screening method for HGH deficiency, particularly in outpatien…
