Background: Thyrotoxicosis is one of the commonest endocrine disorders and its severe form can manifest as thyroid storm in acute setting leading to organ dysfunctions including heart failure. Cases: 1: A 58-year-old female with a significant past medical history of MI, paroxysmal AF/atrial flutter, and hyperthyroidism presented with a one-week history of palpitations, plethora, diaphoresis, heat intolerance, loose stools, and a TSH <0.01; Free T4-33...

Seasonal reproduction enables animals outside tropical regions to rear offspring in a favourable environment. Increasing day length triggers a hypothalamic relay involving thyrotropin, the type 2 deiodinase enzyme and thyroid hormone, which activates the hypothalamic-pituitary-gonadal axis to induce reproductive competence. Photoperiod regulates calcium metabolism and the egg-laying cycle in the Japanese quail (Coturnix japonica), and we hypothesised that activity of ...

Introduction: Incompletely controlled acromegaly has a three-fold excess all-cause mortality, with stroke being the predominant cause of death. Debate exists about the relationship between fractionated radiation (FRT) and risk of stroke, with radiation damage to cerebral vasculature potentially being a cause. We present outcomes in patients treated by gamma knife STRS at the National Centre for Stereotactic Radiosurgery in Sheffield, with...

Sphingosine-1-phosphate lyase 1 insufficiency syndrome (SPLIS) is a multisystemic syndrome in which primary adrenal insufficiency (PAI) and steroid resistant nephrotic syndrome predominate, secondary to loss-of-function mutations in SGPL1 (sphingosine-1-phosphate lyase). SGPL1 carries out the irreversible breakdown of sphingosine-1-phosphate, a bioactive sphingolipid intermediate, with implicated roles in various cellular processes. Wider endocrinopathy including gonadal insuf...

Background: Coronavirus 2019 (Covid-19), an infectious disease caused by SARS-CoV-2 virus has been linked to autoimmunity. Graves’ disease (GD) is a common subtype of paediatric hyperthyroidism and an autoimmune condition, where antibodies stimulate the thyroid-stimulating hormone receptor on the thyroid gland to produce excess thyroid hormone. Although, paediatric GD is rare, incidence have risen before the pandemic, and this rise has accelerated since the Covid-19 pande...

A 33-year-old woman with type 1 diabetes and autoimmune Addison’s disease conceived in September 2021 following careful preconception counselling. The patient had a history of recurrent, severe hypoglycaemia requiring intensive care admission and had previously received two allogenic islet cell transplants (January 2020 and November 2020). The patient had no severe hypoglycaemia following transplantation, although she continued to experience overnight hypoglycaemia, while...

Background: Peptide receptor radionuclide therapy (PRRT) is a promising radiation-based therapy for metastatic neuroendocrine tumors (NETs) but remains palliative. Peptidyl-prolyl cis-trans isomerase (Pin1) is an evolutionally conserved enzyme that catalyzes the cis-trans isomerization of phosphorylated serine/threonine-proline motifs of its substrates and has recently been involved in DNA double strand break (DSB) repair in BRCA-proficient breast cancer cells. Here we study w...

Introduction: Profound thyrotoxicosis commonly presents with heat intolerance, sweating, weight loss, palpitations, tremor, goitre and eye signs in the case of Grave’s disease. Typically, thyroid storm is differentiated by marked volume depletion, congestive cardiac failure, cardiac arrhythmias, confusion, nausea and vomiting, often with extreme agitation. The wide-ranging and systemic manifestations associated with profound hyperthyroidism are mediated through the thyroi...
