Donohue syndrome(DS) is a rare and often lethal autosomal recessive disease. Its prevalence is estimated less than one in a million live births. Mutations in the insulin reseptor (INSR) gene cause rare severe INSR-related insulin resistance syndromes such as DS. It is characterized by severe insulin resistance (hyperinsulinemia, fasting hypoglycemia and postprandial hyperglycemia), intrauterine and postnatal growth retardation, hypotonia, organomegaly including heart, liver, k...

Oedema is a care complication of insulin therapy. It affects mainly patients with newly diagnosed type 1 diabetes mellitus, poorly controlled diabetes mellitus or patients on large doses of insulin. There are only a few case report showing that it is an uncommon and probably an under-reported complication. Two mecanisms are known: the sodium and water retention and vasoactive mediators release. The oedema tends to develop shortly after initiation of insulin therapy and resolve...

Tricho-rhino-phalangeal syndrome Type I (TRPS I) is a rare autosomal dominant genetic disorder clinically characterized by craniofacial and skeletal abnormalities, associated with cone-shaped epiphyses, brachydactyly and short stature. Although patients with TRPS I present various degrees of short stature, there are only four reports of growth hormone deficiency in patients with TRPS I. We present the case of TRPS I and partial GH deficiency. A 15-year-old female was referred ...

Background: Proprotein convertase 1/3 (PC1/3) deficiency, an autosomal-recessive disorder caused by rare mutations in the proprotein convertase subtilisin/kexin type 1 (PCSK1) gene, has been associated with severe malabsorptive diarrhea and certain endocrine abnormalities.Objective and hypotheses: To date, only 13 subjects with PC1/3 deficiency have been reported, now we want to report a new patient who was diagnosed PC1/3 deficiency with novel PCSK1 mut...

Background: Bronchiectasis is a result of recurrent pulmonary infections and chronic inflammation.Objective and hypotheses: Chronic inflammation may lead some endocrinological disorders. The consequences of the bronchiectasis on the endocrinological system and on the bone health in childhood were investigated in this study.Method: The medical records of the 64 children with bronchiectasis (32 females and 32 males) at the mean age o...

Background: Hereditary 1,25-dihydroxyvitamin D resistant rickets (HVDRR) caused by vitamin D defective receptor.Objective and hypotheses: We performed VDR gene analysis four patients with alopecia, skeletal dysplasia, and hypocalcaemia.Method: Genomic DNA extracted from peripheric blood. Whole gene sequence analysis was performed.Results: We found homozigot p.Q152* (c.454G>T) mutation three patients. Two ...

Aim: The most common cause of persistent hypoglycemia and related brain damage in infancy is congenital hyperinsulinism (CHI), due to inappropriate secretion of insülin by pancreatic βcells. The most frequent and most serious mutations are activating mutations in ABBC8 or KCNJ11 genes. Genetic analyses, which might predict the type of lesion, performed in early period and 18f dopa pet scanning are very valuable for treatment choice and follow-up of the patients. In t...

Background: Resistance to thyroid hormone (RTH) is an inherited syndrome characterized by reduced sensitivity of target tissues to thyroid hormone.Objective and hypotheses: We describe the clinical, biochemical data and mutation analysis of two patients and their families with (RTH).Method: We conducted clinical studies and genetic analysis of these two patients and their families.Results: First patient refer...

Background: Wolcott-Rallison syndrome (WRS) is a rare, autosomal recessive disease and characterized by early-onset diabetes, spondyloepiphyseal dysplasia, short stature, osteopenia, acute liver failure, and neurological deficit. It results from mutation in a gene of the eukaryotic translation initiation factor 2-α kinase 3 (EIF2AK3).Objective and hypotheses: We report two WRS patients diagnosed in infantile period.Me...

Background: Early tooth loss could be the consequence of the local or systemic diseases. We present an odontohypophosphatasia case with otosomal dominant mutation in ALPL gene.Objective and hypotheses: We report a case with odontohypophosphatasia and his family investigation.Method: Three-years-old boy admitted to our pediatric endocrinology clinic with toothloss without any other dental or gingival disease. His serum levels calciu...
