Background: Type 1 diabetes mellitus is characterized by presence of several organ specific autoantibodies. Anti-cyclic citrullinated peptide (anti-CCP) antibody is a promising marker of rheumatoid arthritis (RA) which is known to coincide with autoimmune diabetes. Presence of these antibodies was not investigated in children with type 1 diabetes.Objective and hypotheses: To evaluate presence of anti-CCP antibodies in children with type 1 diabetes compar...

Background: Risk of developing germ cell tumors (GCTs) in disorders of sex development (DSD) patients with karyotypes contain Y-chromosome or it’s material (Y) increase with age. The appropriate timing for prophylactic gonadectomy in these patients is still controversial.Aim: To analyze the gonadal tumor incidence and histological assessment of gonads in DSD (Y) patients who were treated in a single institution between 1997 and 03/2018.<p class=...

Background: Mutations in BRAF are a rare cause of cardiofaciocutaneous syndrome (CFC). Recently, BRAF mutations have been reported in papillary craniopharyngiomas, but have not been described in patients with other hypothalamo-pituitary abnormalities. We describe three patients with CFC and septo-optic dysplasia (SOD) associated with heterozygous BRAF mutations.Cases: Patients presented in childhood with clinical features of ge...

Aldosterone synthase deficiency (ASD) is a rare autosomal recessive disease caused by inactivating mutation in the CYP11B2 gene, usually presenting with severe salt-wasting in infancy or stress-induced hyperkalaemia and postural hypotension in adulthood. ASD is unable to be detected by Neonatal screening of 17-hydroxyprogesterone, hence patients would not be diagnosed until they suffer from salt-wasting crisis. Due to this potentially life-threatening risk, early detection and...

Background: It has been previously proposed that not all children with short stature displaying an inadequate response to tests for growth hormone (GH) secretion truly suffer from GH deficiency (GHD). Instead, amongst these, solely children with an identifiable monogenic cause of GHD or an identifiable functional or anatomical anomaly in the hypothalamic-pituitary axis should be considered GHD. The remaining patients should be defined as affected by “sho...

Despite significant advances in the medical management of childhood diseases, glucocorticoids (GCs) continue to be the mainstay of therapy for numerous serious conditions, including hematological malignancies, Duchenne muscular dystrophy (DMD) and inflammatory disorders. In order to understand the natural history of bone development in GC-treated children, a pan-Canadian longitudinal observational research study called "STOPP" (STeroid...

Catch-up growth (CUG) is characterized by a period of supranormal height velocity following a transient period of growth inhibition. The two classical hypotheses on the mechanism are the neuro-endocrine hypothesis (a central mechanism that would recognize the degree of mismatch between actual size and target size) and the growth plate hypothesis (local regulation of growth according to a preset cellular program of senescence, characterized by decreasing growth proliferation ra...

Study of the histopathology of human type 1 and 2 diabetes through the national pancreatic organ donor (nPOD) consortium has yielded interesting new insights that should also aid us in developing improved therapeutic approaches.1. When insulitis is observed, it usually shows a predominance of CD8 T cells, some of which are autoantigen specific (see also Coppieters et al. JEM 2012). It will be therapeutically challenging to remove/prevent CD8 mem...

Background: Cardiovascular disease (CVD) is the major cause of mortality in diabetes mellitus type 1 (T1DM). Dyslipidemia will increase this risk. Several guidelines have been published, how to treat dyslipidemia in T1DM, yet some studies have shown that the number of patients who are treated according to these guidelines is low.Objective and hypotheses: To investigate the frequency of dyslipidemia in children and adolescents with T1DM and if they are tr...

The transient activation of the hypothalamus-pituitary-gonadal (HPG) axis shortly after birth has been described as early as in the 70ies. This discovery has since been applied clinically as a ‘window of opportunity’ for diagnostic evaluation of patients suspected of endocrine disorders and differences of sex development. With the advent of increasingly more sensitive and specific analytical methods for peptide and steroid hormones produced in the pituitary, gonads...
