Case report: A 52-year-old woman developed painful anterior neck swelling seven days after receiving the first COVID-19 vaccine AstraZeneca (AZ). Investigations showed TSH 0.14 mIU/l, CRP 34 mg/l and TRAb 0.3 IU/l. A neck Doppler ultrasound scan on day 15 showed features of thyroiditis. On day 21, she was hyperthyroid with TSH <0.02 mIU/l and free T4 70.3 pmol/l. COVID-19 test was negative, and she was advised to start Carbimazole and propranolol but took only the beta-blo...

Case history: Two Syrian refugee siblings aged 21 and 20 years, were referred. Ambiguous genitalia had been identified at birth and had been raised as males. They wished a more masculine habitus and had concerns regarding their fertility. The elder sibling had ambiguous genitalia at birth and a 46,XX karyotype. Long-term steroid treatment had been initiated and corrective genital surgery performed at 9 months of age. For unknown reasons, steroids were stopped after 9 years. He...

The usefulness of long-term medical treatment with somatostatin analogs has not been evaluated in insulinomas. 22 patients with hypoglycaemia related to endogenous hyperinsulinism (62±21 years, M±S.D., 27–88 years) were not treated by surgery: aged patients (n=10), patients with malignant unresectable insulinomas (n=6; locally invasive, n=1; multimetastatic, n=5), multiple insulinomas (n=2), diffuse beta cell pat...

A 42 year-old man presented in 1994 with a two-week history of headaches, drowsiness and confusion. There had been reduced libido and weight gain for 2 years. There was testicular atrophy and morbid obesity, but no neurological abnormality. CT scan showed a large, partially calcified, suprasellar tumour extending up into the third ventricle. Downward displacement of the posterior clinoid was identified with features of haemorrhage peripherally. MRI scan showed tumour of mixed ...

Background: The European Society of Endocrinology (ESE) published guidelines to standardise intravenous hypertonic saline (HTS) for severe symptomatic hyponatraemia in 2014. Two 150 mL boluses of 3.0% HTS are proposed, one after the other, to achieve an initial sodium rise of 5 mmol/l without waiting for an interval sodium result. ESE guidelines were adopted by our University Hospital in 2017. However, high rates of sodium overcorrection were observed, and the guidelines lacke...

Development of a functional human lung requires regulation of cell growth, proliferation and differentiation in specific germ layer compartments. Important endocrine regulators of respiratory development include glucocorticoid (GC) steroids and the potent synthetic GC betamethasone is commonly used antenatally to treat the deficits of very preterm human birth. Previous studies with conditional mouse knockouts of the glucocorticoid receptor (GR) gene have established the mesenc...

Glucocorticoid (GC) signalling via the glucocorticoid receptor (GR) is essential for normal lung development. Previous work using conditional mouse knockouts of the GR gene established that GR activity in the mesenchymal compartment of the lung is critical for normal respiratory development. Screens for GC-target genes with conditional mesenchymal GR deficient mouse lung (GRmeskO) identified Versican (Vcan), an important extracellular matrix (ECM) component and cell proliferat...

Background: Incidence of hypercalcaemia during pregnancy is difficult to estimate as routine calcium screening is not recommended. Literature is conflicting if hypercalcemia results in worse maternal and fetal outcomes.Objectives: Aim of this study is to determine frequency and association of hypercalcaemia in pregnancy with early maternal and fetal outcomes.Methods: This retrospective cohort study included gestations with expected...

Background: Immigrants from the Middle East to Sweden have a twice as high prevalence of type 2 diabetes (T2D) and obesity as native-born Swedes. Both obesity and T2D have been linked to increased incidence of cancer, cardiovascular disease (CVD) and all-cause mortality (ACM); however, data on differences between ethnicities are scarce. Aims: In a population-based cohort we aimed to study the impact of Middle Eastern and European ethnicity on ACM, cancer...

Introduction: Abnormalities of glycoregulation are frequent in acromegaly (15-38%) secondary to insulin resistance related to GH/IGF-1 hyper-secretion. The frequency of gestational diabetes (GD) in women with acromegaly was reported in the French multicenter study (JCEM, 2010, 95, 4680) as increased mainly in the absence of pre-gestational control of GH/IGF-1 hyper-secretion. The aim of this study was to evaluate the frequency of GD in a cohort of acromegalic women, and compar...
