Aims: To discover the views of patients with Diabetes Insipidus (DI) on difficulties they encounter with managing DI in different circumstances; the possible causes of these difficulties and how these might be improved for their safety.Background: Between 2009 and 2015 there were 471 serious adverse inpatient incidents and 2 deaths involving DDAVP administration1. The analysis of one death resulted in a suggestion that the name of the conditio...

We report a case of a girl with severe short stature (-3.5 SD) from the age of 2 years. She was born at term with a normal birth weight (-1.3 SD) to non-consanguineous Pakistani/British parents. She had global developmental delay, hypotonia and microcephaly (-2.0 SD). She also had juvenile xanthogranuloma, alternating esotropia, constipation and initial feeding difficulties. Her current height is -2.9 SD with a normal BMI, aged 11. Serum IGF1 at age 2 years was <25 (49-289...

Introduction: Obesity has become an international epidemic, with complex multifactorial aetiology. Both modifiable and unchangeable risk factors must be identified, to target public health interventions. Some studies have suggested that earlier pubertal maturation increases risk of adult obesity, although others have found no relationship. We aimed to meta-analyse existing data and hypothesised that any association is likely to be confounded by childhood adiposity.<p class...

There is data suggesting that puberty is starting earlier than in previous generations. However, there is minimal information on menarche and its management in UK primary schools. We present a population study, performed in Islington: a London borough with wide ethnic diversity, conducted using written questionnaires to all primary schools. Data collected included: information on menarche, provision and disposal of sanitary towels and teaching on puberty. 22 (50%) replies were...

We describe the case of a 39-year-old lady who was diagnosed with acromegaly in 1997 with basal GH 89.9 mu/l with paradoxical rise to 152 mu/l on OGTT, her IGF-1 was 76 nmol/l refrange (9.5–45). She underwent transphenoidal hypophysectomy in 1998 for pituitary microadenoma and postoperatively her growth hormone level was 5 mu/l. Six months following surgery she had an OGTT during which she suppressed her growth hormone levels to a nadir of 5 mu/l and her IGF-1 was 46.1 nm...

A 44-year-old Caucasian female eight years previously had been diagnosed auto immune Addison’s disease and started on replacement with hydrocortisone 30 mg daily in divided doses and fludrocortisone 0.1 mg was started on lithium carbonate. One month later when her lithium level was 1.0 mmol/l she was noted to have a sodium of 129 mmol/l, potassium of 5.2 mmol/l and fludrocortisone was increased to 0.3 mg om. Over the next year as her lithium dose was increased as her reni...

We present, the first reported case of twins conceived by Assisted Reproductive Technology (Gamete Intra-fallopian Transfer Therapy; GIFT), both diagnosed to have Complete Androgen Insensitivity Syndrome (CAIS).Eighteen-year-old twins presented to the Endocrine clinic with primary amenorrhoea. They were conceived by GIFT and were born premature at 34 weeks and delivered by forceps. On examination, they were two 18 year olds with normal female appearance,...

We present 2 patients who developed severe thyrotoxic exacerbation following radioiodine. The first treated by conventional antithyroid therapy, the second was plasma exchanged.Patient A aged 39 male with FT3=28.2 pmol/l (2.5–5.3) FT4=49.0 pmol/l (9.1–23.8) TSH=<0.01 mU/l (0.32–5.0),a large diffuse goitre, thyroid eye disease and asthmatic on inhaled ventolin. He received 3.5 years of carbimazole 40 mg and thyroxine 100 mcg. Thyroxine ...

Introduction: Bartter Syndrome types 3 and 4 (BS3/4) are rare tubulopathies, caused by CLCNKB and BSND mutations, which affect chloride channel function in the loop of Henle and distal convolute. Historically, with late presentation and poor disease control, patients had severe short stature. Multiple case reports have also found associations between BS3/4 and Growth Hormone deficiency (GHD). Our aim was to investigate growth and presence of GHD in a large co...

Fibroblast growth factor-23 (FGF23), a phosphate-regulating hormone is elevated in hypophosphataemic syndromes and is a predictor of mortality in patients with kidney disease. Recent findings demonstrate iron deficiency as a potential mediator of FGF23 expression and murine studies have shown in utero effects of maternal iron deficiency on FGF23 and phosphate (P) metabolism and bone formation (Clinkenbeard, JBMR, 2013).The aim of the cu...
