Dysregulated recruitment of leukocytes across endothelial cells into target tissues is a hallmark of the pathology of most chronic inflammatory diseases (CIDs). We have identified a novel homeostatic pathway that regulates T-cell migration during inflammation. The pathway is impaired in patients with CIDs such as type-1-diabetes and rheumatoid arthritis (RA), and is also attenuated in the elderly. The dysregulation of this pathway across all conditions is caused by a lower lev...

Background: A re-emergence of mild iodine deficiency in the United Kingdom (UK) has been reported. A recent UK study suggested a dose dependent relationship between mild maternal deficiency and a number of childhood cognitive scores. The World Health Organisation defines sufficiency in a population as a median urinary iodine concentration (UIC) of ≥100 μg/l in non-pregnant women and infants and ≥150 μg/l during pregnancy. It also recommends a daily intake...

Anonymised therapeutic data has been available for all patients in NI across 364 general practices since 2008. The database records age, gender, trusts and postcodes, which allows for spatial deprivation analyses. Patients were categorised in deciles (1-most deprived, 10-least) according to published criteria. We examined carbimazole (CBZ) and propylthiouracil (PTU) prescriptions over 10 years (2010 to 2019). Patients treated definitively with surgery/radioiodine are invariabl...

Introduction: Anosmin-1, which is implicated in the pathogenesis of X-linked Kallmann`s syndrome, consists of a cysteine rich region, followed by a WAP domain and 4 fibronectin type III (FN3) domains. The N-terminal region of anosmin-1, WAP and 1st FN3 domain, is highly conserved in a wide variety of species which suggests that the activity of the protein resides in these conserved segments. Difficulties in the expression of the full-length anosmin-1 by Chinese hamster ovary c...

18 year old student was referred by the Gynaecology team with primary amenorrhoea, delayed puberty, and minimum breast development. History: The patient was born by an emergency caesarean section with a birth weight of eight pounds and four ounces. She had a normal development during infancy and childhood and there was no reported developmental delay in the family.

History: He was born at full term with a bodyweight of eight pounds and normal development till adolescence. He is the second out of three children and as his parents and siblings entered puberty at expected ages and he has not suffered from the chronic illness make constitutional delay of puberty or functional hypothalamic hypogonadism less l...

Hypophysitis is an inflammatory disorder of the pituitary gland and among them, IgG-4 hypophysitis is rare and presents in less than 5 % of cases.Case: 59 years old lady with a past medical history of asthma presented Rheumatology with? giant cell arthritis due to constant frontal headache, pain behind her eyes, and raised inflammatory markers (ESR 15, CRP 17) three weeks after COVID infection. After review, rheumatology team concluded unlikely giant cel...

Objective: HNF1A gene mutations are the most common cause of monogenic diabetes. Patients with HNF1A–MODY display sensitivity to sulphonylurea therapy, however the long term efficacy has yet to be established. There is also limited literature as to the prevalence of complications in this unique cohort. The aim of the study was to determine the natural progression of HNF1A–MODY diabetes in a dedicated MODY clinic.Design: n=60 H...

Introduction: Sertoli-leydig cell tumours are neoplasms of ovarian sex cord stromal cells and account for 0.5-2% of ovarian tumours with reported incidence <0.5 % of all ovarian tumours. These tumours usually manifest in women at younger age (in 75 % patients average age of onset <30). Majority of these tumours produce hormones and up to 80% of ovarian Sertoli-Leydig cell tumours can manifest with signs of virilization.Case report: 18 year old fe...

Introduction: Crooke’s cell adenomas are nonneoplastic corticotropes with cytoplasmic accumulation of cytokeratin filaments in response to glucocorticoid excess. They are rare subtype of corticotrope adenomas presenting less than 1 % of pituitary adenomas.Case: 52 years old man attended Ophthalmology Clinic with 2 months history of right-sided reduced vision. He had a history of posterior polymorphous corneal dystrophy with a left corneal transplant...
