Context: Polycystic ovary syndrome (PCOS) is a heterogeneous condition affecting women of reproductive age. It is associated with dyslipidaemia and elevated plasma C-reactive protein (CRP), which increase the risks of cardiovascular disease (CVD).Objective: To review the existing evidence on the effects of different pharmacological interventions on lipid profiles of women with PCOS.Data sources: We searched PubMed, MEDLINE, Scopus,...

Background: Congenital hypopituitarism (CH) is characterised by the deficiency of one or more pituitary hormones and can present alone or in association with complex disorders. Congenital hyperinsulinism (CHI) is a disorder of unregulated insulin secretion despite hypoglycaemia that can occur in isolation or as part of a syndrome. The underlying genetic etiology causing the complex phenotype of CH and CHI is unknown.Patient and Methods: A female baby bor...

Introduction: Activating mutations in thyrotropin receptor (TSHR) have been previously described in the context of non-autoimmune hyperthyroidism (familial or sporadic) and thyroid adenomas. We describe, for the first time, a mutation in TSHR contributing to follicular thyroid carcinoma (FTC) in an adolescent girl.Case: A 12-year-old girl presented with a right-sided neck swelling, increasing in size over the previous four weeks. Clinic...

Background: CGM based monitoring can help in development of personalized digital therapeutics programs based on the understanding of the effect of diet, physical activity and medications on everyday blood glucose excursions. The variation in intra-individual glycemic response to the same food has been reported in many studies. Thus, understanding of personalized glycemic response (PGR) of each individual becomes important for effective diabetes management.<p class="abstext...

Hyperthyroidism is common and in iodine-sufficient parts of the world the prevalence of overt hyperthyroidism is estimated to be 0.2% to 1.3%. The treatment options include antithyroid medication (ATD), thyroid surgery, or Radioactive iodine (RAI). The latter is increasingly used as a first line definitive treatment for hyperthyroidism. We reviewed the outcomes of patients who received RAI at our tertiary nuclear medicine department over a 4-year period (May 2015 to Dec 2019) ...

Background: Craniopharyngioma (CP) is a rare sellar or suprasellar epithelial tumour with a prevalence of approximately 2 per million and it occurs either in childhood between the ages of 5 and 14 years or in adulthood between the ages of 50 and 74 years. Histologically, CPs are divided into adamantinomatous, more prevalent in children, and papillary, more prevalent in adults. They are usually benign, but rare cases of malignant CPs have been reported. Clinical presentation is...

Background: Ramadan is the religious month in which Muslims fast from pre-dawn (suhoor) until sunset (iftar), abstaining from all kinds of food, and liquid. The major change in meal times may be challenging for hypothyroid patients on levothyroxine because levothyroxine has a narrow therapeutic index and should be taken on an empty stomach.Objective: We aim to compare pre- and post-Ramadan Thyroid function tests of hypothyroid patients taking levothyroxi...

Human luteinizing hormone (LH) and human choriogonadotropin (hCG) were considered biologically equivalent for decades due to structural similarities and binding to the same receptor (LHCGR). However, LHCGR triggers differential, LH- and hCG-specific, cAMP production, steroidogenesis, ERK and AKT activation and gene expression in granulosa cells. Besides the Gs/cAMP/PKA pathway, hCG and LH bioactivity on β-arrestin- and Gq/PLC-dependent pathways are yet to be determined. W...

The most common form of endocrine cancer is differentiated thyroid cancer (DTC). Outcomes of DTC largely depend on radioiodine treatment, which is mediated the sodium-iodide symporter (NIS). However, many tumours exhibit NIS dysregulation, resulting in a poorer prognosis. Since breast cancer can also overexpress NIS, albeit of limited function, radioiodine treatment may be a promising treatment option. Our previous data show that overexpression of the pituitary tumor-transform...

Background: Delivery of clinical trials to time and target is critical for studies to be financially viable and relevant. Feasibility studies are informative. However, protocol acceptability and recruitment rates can only be accurately ascertained once a study is open.The SCIPI study (SubCutaneous Insulin: Pumps or Injections?), randomises patients to treatment with multiple daily injections (MDI) or pumps at diagnosis of type I diabetes (TID). A consent...
