A 27 year old lady with a background of Langerhans cell histiocytosis (LCH) presented to endocrinology clinic for investigation of thyrotoxicosis. At the age of three years old, she presented with a rash on her forehead, which on biopsy revealed Langerhans cell histiocytosis. She was also noted to have symptoms consistent with diabetes insipidus, for which she remains on desmopressin therapy. At the age of six she received pituitary radiotherapy and 6 years ago developed secon...

Aim: An increasing proportion of patients are referred to endocrine clinics for assessment of an endocrine reason for obesity. The aim of our study was to assess the hormone profiles of patients referred for bariatric surgery.Methods: Patients referred to bariatric surgery clinic were investigated for hypothyroidism (TSH, T4), Cushing’s disease (2 mg-overnight dexamethasone suppression test), acromegaly (IGF1) and Vitamin D deficiency (PT...

Introduction: The clinical differentiation between androgen insensitivity syndrome (AIS) and 5 alpha reductase deficiency (5-ARD) can be difficult. Presenting features may be similar and initial investigations may still not be discriminatory.Methods: Case notes on a total of ten patients with the initial diagnosis of AIS or 5-ARD were retrospectively reviewed.Results: All ten children had a 46XY male karyotype. Four children were r...

Bronchopulmonary neuroendocrine tumors (BP-NETs) comprise 20% of all lung cancers. Typical low grade carcinoid tumors (TC) represent the majority of BP-carcinoids. Intermediate grade atypical carcinoid tumors (AC) are less often encountered but more aggressive. Although metastatic dissemination to mediastinal lymph nodes as well as liver, skeleton, central nervous system, skin and mammary glands is well known, the involvement of endocrine glands is really rare.<p class="ab...

The development and maturation of kisspeptin neurons is critical for activating GnRH release needed to initiate puberty. However, little is known of the development and organization of kisspeptin neurons in the human hypothalamus and the anatomical architecture of kisspeptin neurons in rodents is distinct from that of primates.The aim of the present study was to examine the development of the hypothalamic neuroendocrine circuitry that sets the structural...

Introduction: Benign prostatic hypertrophy is common amongst elderly men, and usually treated with the testosterone blocker, finasteride. However, the treatment of such a condition alongside hypo-pituitarism and low testosterone levels presents with a therapeutic dilemma.Case report: An 88-year-old gentleman who was admitted following recurrent episodes of confusion and falls was found to have a serum sodium level of 114 mmol/l, serum osmolality of 258 m...

Introduction: Cerebral ischaemic events in young patients due to patent foramen ovale are rare. A more plausible diagnosis had clouded the initial management and diagnosis of such a case in a young male patient.Case report: A 19-year-old gentleman was admitted with vomiting and profound hyponatraemia of 99 mmol/l. He was diagnosed to have Addison’s disease (with positive adrenal antibodies) following a flat short synacthen test. He warranted ITU adm...

A 45-year-old woman presented with a 6-week history of constipation and generalised abdominal pains. Blood biochemistry revealed a corrected serum calcium of 4.99 mmol/l, phosphate 0.82 mmol/l, and intact parathyroid hormone (i-PTH) of 0.2 pmol/l (normal range 1–6.1 pmol/l). Serum parathyroid hormone related peptide (PTH-rP) was 5.3 pmol/l (normal range <1.8 pmol/l). Computed tomography demonstrated an 11.0×11.6 cm ovarian tumour with cystic and solid areas and h...

Background: In 1998 the UKPDS study showed that over 10 years of observation there were no significant changes in haemoglobin A1c (HbA1c) in intensive insulin therapy group compared with conventional therapy group. Therefore, we still need new options to treat diabetes. Diabetes mellitus type 2 (DMT2), is one of the MS components. Obesity leads to insulin resistance (IR) and DMT2. Androgen deficiency (AD) is well-known factor to predict the development of diabetes.<p class...

Introduction: Klinefelter syndrome (KS) is the most common sex-chromosome disorder with a prevalence of 1 in every 660 men, but only 25% of the expected number of patients are diagnosed. It is also one of the most common endocrine disorders, and takes the third place after diabetes mellitus and thyroid gland diseases. KS is one of the most frequent causes of hypogonadism in men. It is known that hypogonadism in men has been found to be an independent risk factor for developmen...
