Surgery for acromegaly: Indications and goals.

Acromegaly is a disease that occurs secondary to high levels of GH, most often from a hormone-secreting pituitary adenoma, with multisystem adverse effects. Diagnosis includes serum GH and IGF-1 levels, and obtaining an MRI pituitary protocol to assess for a functional pituitary adenoma. Attempted gross total resection of the GH-secreting adenoma is the gold standard in treatment for patients with acromegaly for a goal of biochemical remission.

Cushing Disease: Medical and Surgical Considerations.

Cushing disease is a disorder of hypercortisolemia caused by hypersecretion of adrenocorticotropic hormone by a pituitary adenoma and is a rare diagnosis. Cushing disease presents with characteristic clinical signs and symptoms associated with excess cortisol, but diagnosis is difficult and often relies on repeated and varied endocrinologic assays and neuroradiologic investigations. Gold standard treatment is surgical resection of adrenocorticotropic hormone-secreting pituitary adenoma, which is curative.

Modern Linear Accelerator-Based Radiotherapy Is Safe and Effective in the Treatment of Secretory and Nonsecretory Pituitary Adenomas.

Background: Adjuvant radiotherapy (RT) can help achieve local control (LC) and reduce hormonal overexpression for pituitary adenomas (PAs). Prior reports involved Gamma Knife or older linear accelerator (LINAC) techniques. The aim of this study was to report long-term outcomes for modern LINAC RT.

Racial Disparities in Acromegaly and Cushing's Disease: A Referral Center Study in 241 Patients.

Methods: This is a retrospective study of consecutive patients operated at a large-volume pituitary center.

Functioning Crooke Cell Adenomas: Case Series and Literature Review.

Background: Crooke cell adenomas (CCAs) are rare, potentially aggressive pituitary adenomas. Data regarding prevalence and clinical course are sparse.

Methods: We performed a retrospective review of 59 consecutive functioning corticotroph adenomas operated on between October 2017 and November 2020 and a literature review of CCA publications since 1991.

The genomic profiling and MAMLD1 expression in human and canines with Cushing's disease.

Background: Cushing's disease (CD) is defined as hypercortisolemia caused by adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas (corticotroph PA) that afflicts humans and dogs. In order to map common aberrant genomic features of CD between humans and dogs, we performed genomic sequencing and immunostaining on corticotroph PA.

Methods: For inclusion, humans and dog were diagnosed with CD.

Pituitary society expert Delphi consensus: operative workflow in endoscopic transsphenoidal pituitary adenoma resection.

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.

Pituitary Neoplasm Nomenclature Workshop: Does Adenoma Stand the Test of Time?

The designates pituitary neoplasms as adenomas. A proposed nomenclature change to pituitary neuroendocrine tumors (PitNETs) has been met with concern by some stakeholder groups. The Pituitary Society coordinated the Pituitary Neoplasm Nomenclature (PANOMEN) workshop to address the topic.

Rare Case of a Disappearing Pituitary Adenoma During the Coronavirus Disease 2019 (COVID-19) Pandemic.

We present a case of a 28-year-old woman with a history of severe headaches and pituitary insufficiency. She was found to have a large, enhancing, sellar mass consistent with a pituitary adenoma. The patient's surgical care was delayed due to the coronavirus disease 2019 (COVID-19) pandemic, and follow-up imaging revealed spontaneous involution of the sellar mass.

Incidentally detected acromegaly: single-center study of surgically treated patients over 22 years.

Acromegaly is a rare disease associated with comorbidities that are common in the general population. Most patients undergo screening for classic phenotypical (CP) or mass effect manifestations. By retrospective review of pituitary tumor surgeries performed between 1994 and 2016 (1836), we identified patients with acromegaly (112).

Risk Factors for Rhinosinusitis After Endoscopic Transsphenoidal Adenomectomy.

Objective: Patients undergoing endoscopic transsphenoidal adenomectomy (eTSA) for pituitary tumors are at risk for postoperative complications, including rhinosinusitis. We aimed to determine if preoperative sinonasal disease is a risk factor for postoperative rhinosinusitis (PRS).

Study Design: Retrospective review.

Sheltered Neurosurgery During COVID-19: The Emory Experience.

Background: The 2019 novel coronavirus disease (COVID-19) pandemic has directly and indirectly impacted health care systems, including residency programs. Social distancing, cancellation of elective cases, and staff re-deployment have compromised clinical and academic teaching. We describe the neurosurgical experience at Emory University during the COVID-19 pandemic and the impact of COVID-19-related policies on resident experience.

Status of Pituitary Surgery During the COVID-19 Pandemic.

Even in ideal circumstances, the performance of safe and effective endoscopic transsphenoidal pituitary surgery requires complicated orchestration of care amongst multiple medical and surgical teams in the preoperative, intraoperative, and postoperative settings. The current COVID-19 pandemic further complicates this highly orchestrated effort. Healthcare systems around the globe are working to adapt to the rapidly changing healthcare landscape as information about the SARS-CoV-2 virus is discovered and disseminated.

Spontaneous Skull Base Cerebrospinal Fluid Leaks and Their Relationship to Idiopathic Intracranial Hypertension.

Background: The association between spontaneous skull base cerebrospinal fluid (CSF) leaks and idiopathic intracranial hypertension (IIH) has been suggested, but its significance remains unclear.

Objective: To estimate the prevalence of IIH in spontaneous skull base CSF leak patients.

Methods: Systematic collection of demographics, neuro-ophthalmic and magnetic resonance imaging evaluation of spontaneous skull base CSF leak patients seen pre- and post-leak repair in one neuro-ophthalmology service.

Trends in endoscopic and microscopic transsphenoidal surgery: a survey of the international society of pituitary surgeons between 2010 and 2020.
