Background: The Low dose dexamethasone suppression test (LDDST) is an important investigation for suspected Cushing’s Syndrome (CS). The traditional definition of normal suppression of serum cortisol to ≤50 nmol/l during the LDDST (0.5 mg 6 hrly × 48 h) comes from a time when biochemical autoanalysers did not routinely detect very low values. Previous studies reported 5.1–8.3% of patients with Cushing’s Disease (CD) suppressed to <50 nmol/l at 48 ...

Background: Foramen magnum stenosis (FMS) is a life-threatening complication in children with achondroplasia (ACH) which may require cervicomedullary decompression (CMD). There is no evidence if FMS and CMD affects growth in children with ACH.Aim: To evaluate the impact of FSM and CMD surgery on anthropometric measurements in children with ACH.Methods: Sixty-five patients with ACH ...

Introduction: Short stature is frequently caused by SHOX variants causing functional deficiency. SHOX resides in the pseudoautosomal region (PAR1) of the sex chromosomes and SHOX/enhancer alterations result in a broad phenotypic range: from Langer mesomelic dysplasia, Léri-Weill dyschondrosteosis to idiopathic short stature (ISS). Growth hormone (GH) therapy is indicated for those individuals with short stature due to SHOXdeficiency. A frequent limitati...

Background: Dyshormonogenic hypothyroidism is classically a monogenic disease with recessive inheritance. Thyroid dysgenesis showed a multigenic origin in a mouse model of double-heterozygous deletions of Nkx2.1/Pax8 transcription factor genes, suggesting a possible polygenic nature of certain cases of human hypothyroidism.Objective and Hypotheses: To investigate genetic traits of polygenic involvement in dyshormonogenic hypothyroidism,...

Background: Septo-optic dysplasia (SOD) is a highly heterogeneous condition with a variable phenotype, defined as two or more features of the classical triad: i) optic nerve hypoplasia, ii) midline brain defects, and iii) pituitary hormone abnormalities.Objective and hypotheses: To describe the clinical, endocrine, and neuroimaging features in eight children with SOD.Method: Eight (six males) consecutive patients, diagnosed with SO...

Background: Congenital adrenal hyperplasia (CAH) due to steroid 11β-hydroxylase deficiency is the second most common form of CAH, resulting from a mutation in the CYP11B1 gene. Steroid 11β-hydroxylase deficiency results in excessive mineralcorticoids and androgen production leading to hypertension, virilisation, and ambiguous genitalia of genetically female infants.Objective: The aim of the study was to identify the molecular detect ca...

Aim: To identify factors affecting compliance to treatment with recombinant growth hormone (rhGH) in children with growth hormone deficiency (GHD).Study population and Methods: The following data were collected during standard visits in 8 endocrine clinics in Poland: medical history, auxological measurements, laboratory tests and the numbers of empty and full rhGH ampoules dispensed and returned by the patients. The obse...

Background: Abnormalities in the hypothalamo-pituitary-gonadal axis have been reported in Noonan syndrome (NS) males but few data are available in female patients. Objective: The aim of this retrospective study was to evaluate the gonadal function of female patients with NS and to look for genotype-phenotype correlations. Patients and Methods: The study population included 19 girls/adolescents with a genetically confirmed diagnosis of NS and with available cli...

Background: A decrease in random LH concentration is observed after initiation of treatment for central precocious puberty (CPP), but the suitability of random LH concentrations for assessing efficacy is controversial. Although Neely et al. reported that random LH values frequently fail to demonstrate suppression to prepubertal levels,1 Lee et al. demonstrated that a cutoff of random LH <0.6 IU/l may be adequate for monitoring s...

Introduction: Isodicentric Y chromosome[idic(Y)] is one of the most common structural abnormalities of the Y chromosome and has been observed in patients with disorders of sexual development. Most idic(Y) chromosomes are found in mosaic form with a 45, X cell line.Methods: The aim of this study was to investigate the genotype and phenotype variability of patients with idic(Y). The clinical data from five patients was ext...
