Introduction: Sulfation is required for the metabolism of numerous compounds, including proteoglycans, steroid hormones, neurotransmitters, toxic chemicals, and drugs like acetaminophen. The sulfate transporter SLC13A1 is responsible for the intestinal absorption and the renal reabsorption of inorganic sulfate, but loss-of-function mutations in this gene have never been described in man. Here, we describe a male with a biallelic loss-of-function variant, i.e.,...

Management of Neonatal Hypoglycaemia

Mohnike Klaus

Transition from intrauterine to extrauterine life is a vulnarable time and needs special attention by health professionals. Although only a small group of infants are at-risk for transitory, recurrent or permanent hypoglycemia prompt diagnosis and effective treatment had to avoid permanent brain injury. Neonatologists are aware of hypoglycemia in premature as well as in small for gestational age infants, however lower limits of blood glucose are often debated with endocrinolog...

New Insights in Thyroid Development

Nilsson Mikael

The mammalian thyroid gland stands out in comparison to other organs as it develops from no less than three independent anlagen that originate in anterior endoderm. The median or central anlage present in the pharyngeal floor gives rise to the thyroid bud or diverticulum that provides progenitors to the thyroxin-producing follicular cells. Bilaterally, the ultimobranchial bodies bud off from the inferior-most pharyngeal pouch. Until recently those structures were considered me...

Case Report on Hyperinsulinism/hyperammonaemia Syndrome: An Easily Treatable Cause of Postprandial Hypoglycaemia

Seneviratne Sumudu , Jayatunge Tharanga , Atapattu Navoda , De Silva K. S. H. , Wickramasinghe V. P. , De Silva Harendra

Background: Hyperinsulinism/hyperammonaemia (HI/HA) syndrome is associated with postprandial hypoglycaemia and mild hyperammonemia. There is increased insulin release following protein ingestion, which is amenable to diaxozide therapy. While developmental delay and normoglycaemic seizures can also occur, hepatomegaly has not been reported. We report a child with HI/HA and hepatomegaly, mild learning difficulty and obesity, who was initially mistaken to have glycogen storage di...

Adverse Effects after Priming with Testosterone in Short Statured Boys before Growth Hormone Stimulation Test

Albrecht Andrea , Penger Theresa , Marx Michaela , Voelkl Thomas , Hirsch Karin , Doerr Helmuth G

Background: Current guidelines recommend the priming with low-dose testosterone in prepubertal boys prior to growth hormone stimulation tests. To our knowledge, only few adverse events after low-dose testosterone have been described so far.Objective and hypotheses: To assess possible side effects of testosterone priming.Patients: We studied 188 prepubertal boys aged between 10 and 15 years (mean ± S.D.: 11.4&#17...

Primary Thirst Defect is a Rare But Important Complication Following Surgery for Hypothalamic Hamartoma and Intractable Epilepsy

Giri Dinesh , Blair Jo , Das Urmi , Dharmaraj Poonam , Senniappan Senthil , Malluci Connor , Benedetta Pettorini , Pizer Barry , Burns Sasha , Didi Mohammed

Background: Diabetes insipidus (DI) is a well-recognized post neuro surgical complication arising after hypothalamic-pituitary surgery. DI occurring in the post-operative period can be transient happening within 24–48 hour of surgery, secondary to trauma to the connections between the magnocellular bodies and the nerve terminals in the posterior pituitary, or to axonal shock from disturbances in the vascular supply to the pituitary stalk and posterior pituitary.<p cla...

Background: Aromatase inhibitors (AI) are being used in clinical trials in children related to peripheral precocious puberty, and idiopathic short stature to improve height prognosis.Case report: A 2 11/12 year-old boy was referred to our center for evaluation of penile enlargement and pubic hair development. Physical examination revealed a well-developed muscular boy with a body weight of 22 kg (>97p), height of 110.1 cm (>97p), with ...

Acute Exposure of Endocrine Disruptor does not Induce Oxidative Stress in the Rat’s Brain

Kumar Neeraj , Sharma Varsha

Background: The ever increasing uses of electronic gadgets are becoming a widespread source of Bisphenol-A accumulation. As studies have been reported that low level BPA accumulation may produce neurological effects but still limited studies have re-examined for its adverse effects in terms of acute exposure from electronic devices.Objective and hypotheses: To investigate the effects of BPA on oxidative damage in terms of activity level of antioxidant en...
