Título : Pituitary society expert Delphi consensus: operative workflow in endoscopic transsphenoidal pituitary adenoma resection Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2021 Títulos uniformes : Pituitary Idioma : Inglés (eng) Palabras clave : Consensus Delphi Endoscopic endonasal Endoscopic transsphenoidal surgery Pituitary Pituitary adenoma Skull base surgery Resumen : Purpose: Surgical workflow analysis seeks to systematically break down operations into hierarchal components. It facilitates education, training, and understanding of surgical variations. There are known educational demands and variations in surgical practice in endoscopic transsphenoidal approaches to pituitary adenomas. Through an iterative consensus process, we generated a surgical workflow reflective of contemporary surgical practice. Methods: A mixed-methods consensus process composed of a literature review and iterative Delphi surveys was carried out within the Pituitary Society. Each round of the survey was repeated until data saturation and > 90% consensus was reached. Results: There was a 100% response rate and no attrition across both Delphi rounds. Eighteen international expert panel members participated. An extensive workflow of 4 phases (nasal, sphenoid, sellar and closure) and 40 steps, with associated technical errors and adverse events, were agreed upon by 100% of panel members across rounds. Both core and case-specific or surgeon-specific variations in operative steps were captured. Conclusions: Through an international expert panel consensus, a workflow for the performance of endoscopic transsphenoidal pituitary adenoma resection has been generated. This workflow captures a wide range of contemporary operative practice. The agreed "core" steps will serve as a foundation for education, training, assessment and technological development (e.g. models and simulators). The "optional" steps highlight areas of heterogeneity of practice that will benefit from further research (e.g. methods of skull base repair). Further adjustments could be made to increase applicability around the world. Mención de responsabilidad : Hani J. Marcus, Danyal Z. Khan, Anouk Borg, Michael Buchfelder, Justin S. Cetas, Justin W.

Título : Pituitary society guidance: pituitary disease management and patient care recommendations during the COVID‐19 pandemic—an international perspective Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2020 Títulos uniformes : Pituitary Idioma : Inglés (eng) Palabras clave : Acromegaly COVID-19 Cushing’s disease Pituitary disease and surgery Prolactinomas SARS-CoV-2 Resumen : Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the viral strain that has caused the coronavirus disease 2019 (COVID-19) pandemic, has presented healthcare systems around the world with an unprecedented challenge. In locations with significant rates of viral transmission, social distancing measures and enforced 'lockdowns' are the new 'norm' as governments try to prevent healthcare services from being overwhelmed. However, with these measures have come important challenges for the delivery of existing services for other diseases and conditions. The clinical care of patients with pituitary disorders typically involves a multidisciplinary team, working in concert to deliver timely, often complex, disease investigation and management, including pituitary surgery. COVID-19 has brought about major disruption to such services, limiting access to care and opportunities for testing (both laboratory and radiological), and dramatically reducing the ability to safely undertake transsphenoidal surgery. In the absence of clinical trials to guide management of patients with pituitary disease during the COVID-19 pandemic, herein the Professional Education Committee of the Pituitary Society proposes guidance for continued safe management and care of this population.

Título : Physicians' awareness of gadolinium retention and MRI timing practices in the longitudinal management of pituitary tumors: a "Pituitary Society" survey Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2019 Títulos uniformes : Pituitary Idioma : Inglés (eng) Palabras clave : Adenoma Contrast Gadolinium Imaging Neuroendocrinologists Neurosurgeons Pituitar Safety Survey Tumor Resumen : Purpose: In view of mounting attention related to possible brain retention of gadolinium-based contrast agents (GBCAs) in patients with normal renal function, our purpose was to detail results from a survey of pituitary experts to assess: 1) the timing interval and frequency of pituitary magnetic resonance imaging (MRI) following surgical and/or medical and/or radiation therapy of pituitary tumors, 2) awareness of the types of GBCAs used and their possible safety issues. Methods: The Pituitary Society Education Committee composed a survey with 12 multiple choice questions, 8 of which specifically addressed the time interval and frequency of MRI in the longitudinal management of pituitary tumors. The survey was distributed at two meetings; the International Pituitary Neurosurgeons Society conference in San Diego, CA, on February 18th, 2018, and the Pituitary Society Membership and Career Development Forum, Chicago, IL on March 18th, 2018. Results: There is consensus among pituitary endocrinologists and neurosurgeons that long-term repeated imaging is recommended in most pituitary tumors, although the precise strategy of timing varied depending on the specialist group and the specific clinical context of the adenoma. The data also suggest that International Pituitary Neurosurgeons Society neurosurgeons, as well as Pituitary Society neuroendocrinologists, are sometimes unaware of which contrast agents are used by their institution, and many are also unaware that evidence of long-term brain retention has been reported with the use of GBCAsin patients with normal function. Conclusions: International pituitary endocrinologists and pituitary neurosurgeons experts suggest ongoing MRIs for the management of pituitary tumors; strategies vary based on clinical context, but also on individual experience and practice.

Título : Pituitary pathology in traumatic brain injury: a review Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2019 Títulos uniformes : Pituitary Idioma : Inglés (eng) Palabras clave : Hypothalamic-pituitary autoimmunity (HP-A) pathology pituitary post traumatic hypopituitarism (PTHP) Traumatic brain injury (TBI) Resumen : Purpose: Traumatic brain injury most commonly affects young adults under the age of 35 and frequently results in reduced quality of life, disability, and death. In long-term survivors, hypopituitarism is a common complication. Results: Pituitary dysfunction occurs in approximately 20–40% of patients diagnosed with moderate and severe traumatic brain injury giving rise to growth hormone deficiency, hypogonadism, hypothyroidism, hypocortisolism, and central diabetes insipidus. Varying degrees of hypopituitarism have been identified in patients during both the acute and chronic phase. Anterior pituitary hormone deficiency has been shown to cause morbidity and increase mortality in TBI patients, already encumbered by other complications. Hypopituitarism after childhood traumatic brain injury may cause treatable morbidity in those survivors. Prospective studies indicate that the incidence rate of hypopituitarism may be ten-fold higher than assumed; factors altering reports include case definition, geographic location, variable hospital coding, and lost notes. While the precise pathophysiology of post traumatic hypopituitarism has not yet been elucidated, it has been hypothesized that, apart from the primary mechanical event, secondary insults such as hypotension, hypoxia, increased intracranial pressure, as well as changes in cerebral flow and metabolism may contribute to hypothalamic-pituitary damage. A number of mechanisms have been proposed to clarify the causes of primary mechanical events giving rise to ischemic adenohypophysial infarction and the ensuing development of hypopituitarism. Conclusion: Future research should focus more on experimental and clinical studies to elucidate the exact mechanisms behind post-traumatic pituitary damage. The use of preventive medical measures to limit possible damage in the pituitary gland and hypothalamic pituitary axis in order to maintain or re-establish near normal physiologic functions are crucial to minimize the effects of TBI.

Título : Pathology of GH-producing pituitary adenomas and GH cell hyperplasia of the pituitary Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2017 Títulos uniformes : Pituitary Idioma : Inglés (eng) Palabras clave : Acromegaly classification diagnosis immunohistochemistry pathology pituitary neoplasms Resumen : Introduction: Histologic, immunohistochemical and electron microscopic studies have provided conclusive evidence that a marked diversity exists between tumors which secrete growth hormone (GH) in excess. GH cell hyperplasia can also be associated with acromegaly in patients with extrapituitary GH—releasing hormone secreting tumors or in familial pituitary tumor syndromes. Materials and methods: A literature search was performed for information regarding pathology, GH-producing tumors and acromegaly. Results: This review summarizes the current knowledge on the morphology of GH-producing and silent GH adenomas, as well as GH hyperplasia of the pituitary. Conclusion: The importance of morphologic classification and identification of different subgroups of patients with GH-producing adenomas and their impact on clinical management is discussed.
