Background: Achondroplasia is a skeletal dysplasia being the most common cause of rhizomelic dwarfism.Case presentation: We present a 10 years old boy who was first diagnosed prenatally. He had a mutation c1138G>A in the gene FGFR3 in a heterozygotic constellation. His IGF1 levels and IGFBP3 were normal. Two stimulation tests for GH were performed with normal levels of the hormone. His psychomotor development was adequate for his age except for speec...

Background: Congenital glucose–galactose malabsorbtion is a rare autosomal recessive disorder of intestinal transport of glucose and galactose. It is characterized by watery diarrhoea, dehydration, failure to thrive, or early death without appropriate dietary treatment.Case presentation: The patient was 15 days old when he was admitted to the hospital because of continued, severe, watery, acidic diarrhoea and hypernatremic dehydration. The abnormal ...

Background: Hashimoto’s thyroiditis is a common autoimmune disease in pubertal and adolescent girls. In the past years the incidence of this autoimmune disease of the thyroid gland has increased.Objective and hypotheses: We present a 12.5 year old girl who had her first visit at our Pediatric Endocrinology Department at the age of 10 years due to short stature and clinical signs of hypothyroidism. Her height was – 3SD SDS and her BMI was 12.7. ...

Background: Hypophosphatasia (HP) is a rare inherited disorder characterised by defective bone and teeth mineralization because of deficient serum and bone alkaline phosphatase activity due to mutations in the tissue-nonspecific ALP (TNALP) gene. Infantile HP (IHP) is one of the six recognized clinical forms according to age at presentation and clinical features. IHP is characterised by skeletal abnormalities due to demineralization and rachitic changes in the metaphyses, prem...

Introduction: Central hypothyroidism is due to a deficiency of TRH/TSH.Patient and Methods, Results: A 9 year old boy (07 Aug. 20) was referred for proportionate short stature (-2.7 SD). He complained of fatigue and had mild peripheral edema. His baseline T4 was 2.9 ug/dL(ref. 4.50-12.50 ug/dL) and TSH 0.04 uIU/ml (0.400-4.00). The TRH test showed low TSH <0.004 Ulu/ML (ref. 0.400-4.00) and low T4 2.70 (ref. 4.50-12....

Background: Nephrogenic diabetes insipidus (NDI) is caused by inability of renal collecting duct cells to respond to arginine vassopresin (AVP)/antidiurethic hormone (ADH).Objective and hypotheses: The majority of patients (about 90%) have type 1, X-linked recessive form, of NDI caused by mutation in gene encoding the vassopresin V2 receptor. Type 2, autosomal NDI, have the rest 10% of patients. This type is caused by the aquaporin-2 water channel (AQP2)...

Congenital panhypopituitarism is a rare cause of impaired metabolism in early infancy. Many guidelines for neonatal hypoglycemia include evaluation of pituitary hormones, but other parameters of metabolism (either mineral, lipid or hepatic) are rarely taken into consideration and don’t regularly suggest hormonal investigation. Therefore the diagnosis of multiple hormonal deficiencies is often late at that age. Although many reports point to the impaired bile discharge, a...

Introduction: Disorders of sexual development (DSD) include etiologically heterogeneous group of patients that have disorders of genital development. Consensus guidelines that are currently used, divide all DSD in three main groups - sex chromosomal abnormalities, XX or XY DSD, all divided in subgroups in dependence of genetics and hormonal tests. The phenotypic spectrum of external genitalia, gonads and development of Wolfian and Mulerian duct derivatives var...

Background: Obesity is a complex disease that have an impact of many organs and systems. Syndromic obesity, although rare separately, encompasses around 70 entities with different phenotypic expression, gene involvement and associated anomalies. There are many genes that can influence obesity, either monogenic or polygenic in basis. Children with syndromic obesity need additional testing in order to indentify a specific disorder. Metabolic set up and endocrinological disturban...
