Introduction: Islet hyperplasia and nesidioblastosis are described in the non neoplastic pancreas of patients with gastrinoma. It is not definately established whether hypergastrinemia can influence these changes. Moreover, rarely insulinoma and gastrinoma occur in the same patient but cases of single tumours cosecreting both insulin and gastrin have been described. Otherwise, the syndrome of hyperinsulinemic hypoglycaemia with nesidioblastosis after Roux-en-Y gastric bypass h...

Introduction: Pancreatic neoplasms portray the 12th most prevalent neoplasm worldwide, determining a five-year survival of only 5 to 10% including all stages. Despite tumoral aggressiveness, the modified Appleby procedure can be performed in selected patients, representing a curable alternative in borderline-resectable or locally advanced pancreatic tumors’ treatment in the context of a multimodal practice. Objectives: This work aims to review the state of the art regardi...

Oxytocin was discovered by Henry Dale in 1906 and synthesized in the early 50’s by Vincent du Vigneaud and coworkers. It is secreted by axonal terminals in the neurohypophysis emanating from the neurosecretory neurons of the supraoptic and paraventricular nuclei of the hypothalamus. This hormone similarly to others is secreted in a pulsatile way and, classically, in relation to labor (uterine contractility), lactation and to the maternal behaviour. After the initial ident...

A 69-year-old lady presented to the ophthalmologists in view of a right 6th cranial nerve palsy and headache. Neuroimaging showed a central and right sided base of skull tumour with involvement of multiple cranial nerves (3rd, 4th, 6th). An endoscopic biopsy was inconclusive. She presented to the medical team few days later with drowsiness, lethargy, and her sodium was found to be 117 mmol/l with a potassium of 5.5 mmol/l. Serum osmolality was 267 mOsm/kg, urine osmolality was...

Introduction: Trans-axillary surgery is an emerging technique for cervical approach with fantastic cosmetic result. With more than 50 cases treated by our group, we developed our technique with specific safe methodologies.Aims: To present step-by-step technique of trans-axillary endoscopic thyroidectomy.Material and methods: This is a video surgery that uses three trocars and a harmonic scalpel for dissection and ligation. Incision...

Introduction: Endoscopic techniques are uprising in the cervical field mainly because of the exceptional cosmetic results. These surgeries are frequent in the far east Asia but still rare in Europe. We started these approach on November 2014. This paper is a review of our experience.Aims: To present a series of trans-axillary endoscopic thyroidectomy.Material and methods: This is a cohort study of 50 consecutive patients treated by...

Epidemiological studies suggest that hypovitaminosis D is common in patients with primary hyperparathyroidism (PHPT). They have higher levels of serum parathyroid hormone (PTH) and markers of bone turnover, and more frequent fractures than vitamin D replete patients. There are concerns that vitamin D repletion in these patients might exacerbate pre-existent hypercalcaemia, although recent literature suggests this is uncommon.We aimed to determine the eff...

Context: Exogenous oestrogen administration causes prolactinoma formation in rats and there are anecdotal reports of oestrogen treatment and prolactinoma formation in gender reassignment males to females. It remains unclear whether chronic exposure to high dose oestrogen in women is linked with prolactinoma development.Aim: The aim of this study was to determine the effect of high dose subcutaneous estrogen on prolactin and gonadotrophin levels of 101 wo...

Introduction: Pheochromocytomas are tumors derived from the adrenal-medullary chromaffin cells that normally produce catecholamines. Rarely these tumors are non-secreting. In the assessment of a suspected pheochromocytoma, guidelines recommend dosing urinary or plasma metanephrines.Objective: To evaluate the prevalence of pheochromocytomas biochemically non-secreting and their differences.Methods: We searched all patients with meas...

Objective: The aim of this study was to determine the frequencies of vitamin D receptor (VDR) Bsm1, Fok1, ApaI, TaqI and estrogen receptor α (ESR1) PvuII and XbaI polymorphisms in Romanian patients and to investigate their involvement in postmenopausal osteoporosis.Methods: The study was carried out on 82 postmenopausal women, aged over 60, divided into two groups: group 1-postmenopausal women with osteoporosis (34 subjects), group 2-postmenopausal ...
