OBJECTIVE: Data regarding pregnancies in relation to pituitary tumors are limited. The effects of pregnancy on pituitary adenomas and the effects of adenoma itself (hormonal activity, mass effects and pituitary insufficiency) and/or treatment on the ongoing gestation and developing fetus were evaluated. METHODS: The study was a retrospective study. A questionnaire involving questions regarding medical history before index gestation, history of related pregnancy, result of index gestation and postpartum follow-up of the patients was filled by the investigator in one of the eight Referral Endocrinology Centers from Turkey...

In recent years, hypopituitarism caused by traumatic brain injury (TBI) has been explored in many clinical studies; however, few studies have focused on intracranial hypertension and stress caused by TBI. In this study, an intracranial hypertension model, with epidural hematoma as the cause, was used to explore the physiopathological and neuroendocrine changes in the hypothalamic-pituitary axis and hippocampus. The results demonstrated that intracranial hypertension increased the apoptosis rate, caspase-3 levels and proliferating cell nuclear antigen (PCNA) in the hippocampus, hypothalamus, pituitary gland and showed a consistent rate of apoptosis within each group...

Central diabetes insipidus (DI) is a rare clinical entity characterized by low circulating levels of antidiuretic hormone (ADH) presenting with polyuria and volume depletion. Pituitary surgery is the most common cause of central DI in adults. Pituitary and hypothalamic disease, particularly invasive neoplasms, rarely cause DI, being idiopathic cases responsible for the majority of non-surgical cases. HIV patients, especially those with poor virulogical control, are prone to the development of CNS neoplasms, particularly lymphomas...

PURPOSE: Central diabetes insipidus is characterised by arginine vasopressin deficiency. Oxytocin is structurally related to vasopressin and is synthesised in the same hypothalamic nuclei, thus we hypothesised that patients with acquired central diabetes insipidus and anterior hypopituitarism would display an oxytocin deficiency. Moreover, psychological research has demonstrated that oxytocin influences social and emotional behaviours, particularly empathic behaviour. We therefore further hypothesised that central diabetes insipidus patients would perform worse on empathy-related tasks, compared to age-matched and gender-matched clinical control (clinical control-isolated anterior hypopituitarism) and healthy control groups...

OBJECTIVE: Patients with secondary adrenal insufficiency (AI) have an excess mortality. The objective was to investigate the impact of the daily glucocorticoid replacement dose on mortality in patients with hypopituitarism due to non-functioning pituitary adenoma (NFPA). METHOD: Patients with NFPA were followed between years 1997- 2014 and cross-referenced with the National Swedish Death Register. Standardized mortality ratio (SMR) was calculated with the general population as reference and Cox-regression was used to analyse the mortality...

Pituitary abscess is an uncommon pituitary lesion. Its clinical diagnosis can be difficult to distinguish from other pituitary lesions. This pathology is characterised by vague symptoms of headaches, generalised tiredness and hypopituitarism manifestations. A history of recent meningitis, paranasal sinusitis or head surgery can be a suggestive of the source of infection.A 20-year-old man was admitted to neurosurgery department with complain of headache, fatigue, polyuria, polydipsia, blurred vision and sexual dysfunction...

Congenital growth hormone deficiency is a rare disorder with an incidence of approximately 1 in 4,000 live births. Pituitary development is under the control of a multitude of spatiotemporally regulated signaling molecules and transcription factors. Mutations in the genes encoding these molecules can result in hypopituitarism but for the majority of children with congenital hypopituitarism, the aetiology of their disease remains unknown. The proband is a 5-year-old girl who presented with neonatal hypoglycaemia and prolonged jaundice...

INTRODUCTION: Colloid cysts are the most common pathologic lesions of the third ventricle. Although they are histologically benign, they may grow and can cause the hydrocephalus. A 5-year-old male patient underwent to surgery with the diagnosis of colloid cyst. In operation, after the anterior transcallosal approach, the cyst was punctured by syringe and obviously pus aspirated. CONCLUSION: Colloid cysts mostly remain silent and detected incidentally. Although it is rarely defined, rhinorrhea, hypopituitarism, diabetes insipidus, spasmodic torticollis, drop attack, aseptic meningitis, and coexistence with neurocysticercosis have been reported, but this is the first reported case of an infected colloid cyst...

Kickboxing is one of the modern combat sports. The psychophysiological demands of a kickboxing competition require athletes to achieve high thresholds of several aspects of physical fitness. The aim of the current review is to critically analyse and appraise the kickboxer's anthropometric, physiological, physical and psychological attributes with the activity profile and injury epidemiology in order to provide practical recommendations for training as well as new areas of scientific research. The available information shows that both amateur and elite-level male kickboxers are characterized by a higher proportion of mesomorphy with a well-developed muscle mass and low body fat percentage...

Autoimmune polyendocrine syndrome type 1 (APS1) is a rare monogenic autoimmune disorder caused by mutations in the autoimmune regulator (AIRE) gene. High titer autoantibodies are a characteristic feature of APS1 and are often associated with particular disease manifestations. Pituitary deficits are reported in up to 7% of all APS1 patients, with immunoreactivity to pituitary tissue frequently reported. We aimed to isolate and identify specific pituitary autoantigens in patients with APS1. Immunoscreening of a pituitary cDNA expression library identified endothelin-converting enzyme (ECE)-2 as a potential candidate autoantigen...

We report a case of flexion contractures in a patient's legs secondary to postpartum hypopituitarism. A 56-year-old woman presented with a 3-year history of worsening flexion contractures of the hips and knees. On admission, her hips and knees could not be extended, and she had muscle stiffness and tenderness to palpation of the lower extremities. We first suspected stiff-person syndrome or Isaacs' syndrome because of her muscle stiffness. However, multiple hormones did not respond to stimulation tests, and an MRI of the brain showed atrophy of the pituitary gland with an empty sella...

OBJECTIVES: Previous studies have suggested that postoperative hypopituitarism in patients with non-sellar intracranial tumors is caused by traumatic surgery. However, with development of minimally invasive and precise neurosurgical techniques, the degree of injury to brain tissue has been reduced significantly, especially for parenchymal tumors. Therefore, understanding pre-existing hypopituitarism and related risk factors can improve perioperative management for patients with non-sellar intracranial tumors...

Posterior pituitary ectopia has been reported previously in association with optic nerve hypoplasia, as a variant of septo-optic dysplasia. We describe a 14-year-old boy with posterior pituitary ectopia and bilateral optic disc pits. He had hypopituitarism and a reduction in visual acuity to 20/40 in each eye, owing to loss of foveal ganglion cells. Optic pits and posterior pituitary ectopia may have occurred together in the same subject by chance, but the rarity of both conditions suggests a possible association...

REVIEW
Or Cohen-Inbar
Pituitary adenomas represent one of the most common types of intracranial tumors, accounting for 10-20% of intracranial tumors. While their macroscopic appearance and anatomical location are relatively homogeneous, pituitary tumors differ widely, generating a variety of neurological and endocrine clinical sequelae. Treatment options include hormone suppressive medical therapy, microscopic or endoscopic neurosurgical resection, radiosurgery, radiation therapy, or observation depending on the biochemical profile and the clinical status of the patient...

Lymphocytic hypophysitis is an inflammatory /autoimmune disorder that primarily involves the pituitary gland and the pituitary stalk. The common clinical presentations include headache, nausea, vomiting, fatigue, features of hypopituitarism and diabetes insipidus as well as diplopia, orbital pain and bitemporal hemianopia. We report a case of lymphocytic hypophysitis which presented as hemichorea. Neuroimaging showed a mass in the sella tursica region which, on histopathological examination was suggestive of lymphocytic hypophysitis...

The endoscopic endonasal approach is considered an alternative minimally invasive approach for suprasellar craniopharyngiomas. However, the complicated surgical manipulations required by this approach have limited its application. We evaluate whether the approach features a learning curve. Thirty-three patients were retrospectively reviewed and grouped as early (17 patients) and late (16 patient) groups. The operation time, extent of removal, ophthalmology, endocrinology, reconstruction and modifications of standard technique were evaluated...

Through the multicentric international GENHYPOPIT network, 10 transcription factor genes involved in pituitary development have been screened in more than 1200 patients with constitutional hypopituitarism over the past two decades. The present report summarizes the main lessons learned from this phenotype-based genetic screening: (1) genetically determined hypopituitarism does not necessarily present during childhood; (2) constitutional hypopituitarism may be characterized by a pure endocrine phenotype or by various combinations of endocrine deficits and visceral malformations; (3) syndromic hypopituitarism may also be observed in patients with POU1F1 or PROP1 mutations; (4) in cases of idiopathic hypopituitarism, extensive genetic screening identifies gene alterations in a minority of patients; (5) functional studies are imperfect in determining the involvement of an allelic variant in a specific pituitary phenotype...
