PNA Highlights January 2024

“Give a man health and a course to steer, and he’ll never stop to trouble about whether he’s happy or not.”
– George Bernard Shaw
PNA Spotlight: Dr. Paul A. Gardner
This month the PNA Spotlight focuses on Dr. Paul A. Gardner.
Paul A. Gardner, MD, joined the faculty at the University of Pittsburgh Department of Neurological Surgery in 2008 after completing his residency and fellowship training at the University of Pittsburgh. He completed his undergraduate studies at Florida State University, majoring in biochemistry, and received his medical degree from the University of Pittsburgh School of Medicine.
Dr. Gardner completed a two-year fellowship in endoscopic endonasal pituitary and endoscopic and open skull base surgery. His research has focused on evaluating patient outcomes following these surgeries and more recently on genomic and molecular analysis of skull base tumors. Dr. Gardner has been the neurosurgical director of the Center for Cranial Base Surgery at the University of Pittsburgh Medical Center since April of 2008 and, along with Carl Snyderman, MD, of the University of Pittsburgh Department of Ophthalmology, leads a renowned course on endoscopic endonasal surgery three times a year.

PNA Medical Corner: Artificial intelligence and pituitary surgery
The PNA Medical Corner this month features an article co-authored by neurosurgeon Aaron Cohen-Gadol of Indiana University, a longtime member of the PNA. They conclude that A-I and machine learning will improve preoperative planning and surgical strategies in pituitary surgery, but points out challenges on multiple fronts.
Current status of artificial intelligence technologies in pituitary adenoma surgery: a scoping review
- PMID: 38183582 DOI: 10.1007/s11102-023-01369-6
Abstract
Purpose: Pituitary adenoma surgery is a complex procedure due to critical adjacent neurovascular structures, variations in size and extensions of the lesions, and potential hormonal imbalances. The integration of artificial intelligence (AI) and machine learning (ML) has demonstrated considerable potential in assisting neurosurgeons in decision-making, optimizing surgical outcomes, and providing real-time feedback.
The FDA has approved NGENLA (somatrogon-ghla)
The FDA has approved NGENLA (somatrogon-ghla), a once-weekly, human growth hormone analog indicated for treatment of pediatric patients aged three years and older who have growth failure due to an inadequate secretion of endogenous growth hormone.

His answers follow.
• What inspired you to choose your career path?
The variety of deeply impactful effects of pituitary tumors as well as the intricate anatomy around the pituitary.
• What is the primary focus of your work/research?
Patient outcomes including quality of life; genetic research into the sources of tumors as well as differences between different tumor types; impact of surgery of patients
• What do you consider to be the future of your field?
Refining surgical techniques to lessen impact on patients and understanding the genetics of tumors to provide other treatment options
• What should patients know about your field/what deserves more recognition/awareness?
Pituitary surgery is borne out of practice by multidisciplinary teams of ENT and neurosurgery. This kind of collaboration is not common in medicine but leads to better outcomes and even new approaches.
• What would you like to convey about yourself to your patients?
I do my best to understand every person’s story. This helps me apply the knowledge and experience that I have attained over 20 years in practice to that individual to help them best achieve their health goals. This shared decision making allows me to honestly apply my treatments to the utmost of my ability in line with their wishes.
• Why did you get involved with the PNA; what is the extent of your involvement?
I originally became involved after sitting in on a patient support group. I was very impressed with the PNA leadership and passion and inspired to further my work and research with pituitary and similar tumors. I have been involved in the PNA ever since, largely with lectures and promotional support with my and others’ patients.

Abstract
Purpose: Pituitary adenoma surgery is a complex procedure due to critical adjacent neurovascular structures, variations in size and extensions of the lesions, and potential hormonal imbalances. The integration of artificial intelligence (AI) and machine learning (ML) has demonstrated considerable potential in assisting neurosurgeons in decision-making, optimizing surgical outcomes, and providing real-time feedback. This scoping review comprehensively summarizes the current status of AI/ML technologies in pituitary adenoma surgery, highlighting their strengths and limitations.
Methods: PubMed, Embase, Web of Science, and Scopus were searched following the PRISMA-ScR guidelines. Studies discussing the use of AI/ML in pituitary adenoma surgery were included. Eligible studies were grouped to analyze the different outcomes of interest of current AI/ML technologies.
Results: Among the 2438 identified articles, 44 studies met the inclusion criteria, with a total of seventeen different algorithms utilized across all studies. Studies were divided into two groups based on their input type: clinicopathological and imaging input. The four main outcome variables evaluated in the studies included: outcome (remission, recurrence or progression, gross-total resection, vision improvement, and hormonal recovery), complications (CSF leak, readmission, hyponatremia, and hypopituitarism), cost, and adenoma-related factors (aggressiveness, consistency, and Ki-67 labeling) prediction. Three studies focusing on workflow analysis and real-time navigation were discussed separately.
Conclusion: AI/ML modeling holds promise for improving pituitary adenoma surgery by enhancing preoperative planning and optimizing surgical strategies. However, addressing challenges such as algorithm selection, performance evaluation, data heterogeneity, and ethics is essential to establish robust and reliable ML models that can revolutionize neurosurgical practice and benefit patients.

Consecutive resections of double pituitary adenoma for resolution of Cushing disease: illustrative case
Abstract
Background: Double pituitary adenomas are rare presentations of two distinct adenohypophyseal lesions seen in <1% of surgical cases. Increased rates of recurrence or persistence are reported in the resection of Cushing microadenomas and are attributed to the small tumor size and localization difficulties. The authors report a case of surgical treatment failure of Cushing disease because of the presence of a secondary pituitary adenoma.
Observations: A 32-year-old woman with a history of prolactin excess and pituitary lesion presented with oligomenorrhea, weight gain, facial fullness, and hirsutism. Urinary and nighttime salivary cortisol elevation were elevated. Magnetic resonance imaging confirmed a 4-mm3 pituitary lesion. Inferior petrosal sinus sampling was diagnostic for Cushing disease. Primary endoscopic endonasal transsphenoidal resection was performed to remove what was determined to be a lactotroph-secreting tumor on immunohistochemistry with persistent hypercortisolism. Repeat resection yielded a corticotroph-secreting tumor and postoperative hypoadrenalism followed by long-term normalization of the hypothalamic-pituitary-adrenal axis.
Lessons: This case demonstrates the importance of multidisciplinary management and postoperative hormonal follow-up in patients with Cushing disease. Improved strategies for localization of the active tumor in double pituitary adenomas are essential for primary surgical success and resolution of endocrinopathies.
