Endoscopic transsphenoidal surgery for biochemically and clinically non-functioning adenohypophyseal tumours in the elderly: experience from a single UK centre.

PURPOSE: To assess and compare outcome of surgical management of non-functioning pituitary adenohypophyseal tumours in patients under 65-years, and 65-years and older at tertiary neurosurgical referral centre. METHODS: Data was retrospectively analysed from pituitary database. Forty-four patients aged 65 or older (Group 1) and 93 patients under 65 (Group 2) underwent endoscopic trans-sphenoidal surgery (ETSS) between January 2017 and July 2019. The surgical, endocrinological, ophthalmological and radiological outcomes were compared. RESULTS: 6.8% of Group 1 patients had peri-operative surgical complications compared to 12.9% in Group 2 (p = 0.29). Improved visual fields and acuity were seen in 65.2% and 82.8% of Group 1 and Group 2 respectively (p = 0.124), although there were pre-existing ocular problems in 15.9% of Group 1. New hormone deficiencies were observed in 31.8% of Group 1 patients, and 24.7% of Group 2 (p = 0.555). Tumour regrowth/recurrence was seen in 2.3% of Group 1 (p = 0.553). The rate of repeat surgery was 6.8% in the Group 1 and 12.9% in Group 2 (p = 0.28). There was no significant relationship between extent of resection, complications or hormonal deficiency. The mean duration of follow-up was 10.5 ± 13.0 months for Group 1 patients and 13.0 ± 16.0 months for Group 2 patients (p = 0.526). CONCLUSIONS: ETSS for non-functioning pituitary adenohypophyseal tumours is safe and well tolerated in the patients aged 65 and older. Advanced age by itself should not be a contra-indication for ETSS. It is however highly recommended that the care of such patients to be offered at a high volume, dedicated pituitary surgical units.

A survey of teaching undergraduate neuroanatomy in the United Kingdom and Ireland.

BACKGROUND: Medical students' perception of neuroanatomy as a challenging topic has implications for referrals and interaction with specialists in the clinical neurosciences. Given plans to introduce a standardised Medical Licensing Assessment by 2023, it is important to understand the current framework of neuroanatomy education. This study aims to describe how neuroanatomy is taught and assessed in the UK and Ireland. METHODS: A structured questionnaire capturing data about the timing, methods, materials, assessment and content of the 2019/2020 neuroanatomy curriculum in the UK and Ireland medical schools. RESULTS: We received 24/34 responses. Lectures (96%) were the most widely used teaching method, followed by prosection (80%), e-learning (75%), tutorials/seminars (67%), problem-based learning (50%), case-based learning (38%), and dissection (30%). The mean amount of core neuroanatomy teaching was 29.3 hours. The most common formats of assessing neuroanatomical knowledge were multiple-choice exams, spot tests, and objective structured clinical exams. Only 37.5% schools required demonstration of core clinical competency relating to neuroanatomy. CONCLUSIONS: Our survey demonstrates variability in how undergraduate neuroanatomy is taught and assessed across the UK and Ireland. There is a role for development and standardisation of national undergraduate neuroanatomy curricula in order to improve confidence and attainment.
