Abstract
BACKGROUND The World Health Organization declared coronavirus disease 2019 a pandemic on 11th March 2020. There is concern regarding performing endonasal surgical procedures because of a high viral load in the nasopharynx. This paper describes our experience in conducting emergency and urgent endonasal operations during the peak of the coronavirus disease 2019 pandemic in the UK. OBJECTIVES To show the outcome of endonasal surgery during the peak of the coronavirus disease 2019 pandemic and to assess the post-operative rate of nosocomial coronavirus disease 2019 infection. METHODS A retrospective cohort study was conducted of all patients who underwent high priority endoscopic nasal surgery or anterior skull base surgery between 23rd March and 15th June 2020 at University Hospitals Birmingham NHS Trust. RESULTS Twenty-four patients underwent endonasal surgery during the study period, 12 were males and 12 were females. There was no coronavirus-related morbidity in any patient. CONCLUSION This observational study found that it is possible to safely undertake urgent endonasal surgery; the nosocomial risk of coronavirus disease 2019 can be mitigated with appropriate peri-operative precautions.

Abstract
PURPOSE Highlight and characterize manifestations, diagnostic/management approaches and outcomes in a contemporary cohort of patients with pituitary metastases (PM) from a large European pituitary center-over 10 years. METHODS Retrospective review of PM cases between 1/2009 and 12/2018. Clinical, laboratory, imaging data at PM detection and during follow-up were analysed. RESULTS 18 cases were identified (14 females; median age at diagnosis 61.5 years). Most common primary malignancies were lung (39%) and breast (32%). Most frequent presenting manifestation was visual dysfunction (50%). Gonadotrophin, ACTH, TSH deficiency were diagnosed in 85%, 67%, 46% of cases, respectively; diabetes insipidus (DI) was present in 17%. 33% of cases were detected during investigation for symptoms unrelated to PM. PM management included radiotherapy (44%), transsphenoidal surgery (17%), transsphenoidal surgery and radiotherapy (6%) or monitoring only (33%). One-year survival was 49% with median survival from PM detection 11 months (range 2-47). CONCLUSIONS In our contemporary series, clinical presentation of PM has evolved; we found increased prevalence of anterior hypopituitarism, decreased rates of DI and longer survival compared with older literature. Increased availability of diagnostic imaging, improvements in screening and recognition of pituitary disease and longer survival of patients with metastatic cancer may be contributing factors.

Abstract
The objective of this investigation was to present the operative and hardware complications encountered during follow-up of patients with in situ deep brain stimulators. The study took the form of a retrospective chart review on a series of consecutive patients who were treated successfully with insertion of deep brain stimulators at a single centre by a single surgeon between 1999 and 2005. During the study period, a total of 60 patients underwent 96 procedures for implantation of unilateral or bilateral DBS electrodes. The mean follow-up period was 43.7 months (range 6-78 months) from the time of the first procedure. No patients were lost to follow-up or died. Eighteen patients (30%) developed 28 adverse events, requiring 28 electrodes to be replaced. Seven patients developed two adverse events and two patients developed three adverse events. The rate of adverse events per electrode-year was 8%. We observed a higher proportion of early complications (<6 months postoperatively) in patients with Parkinson's disease, while dystonic patients had more late complications (>6 months postoperatively) and no early complications. Thirty per cent of our patients developed an adverse event that could potentially lead to revision of the implanted hardware. In patients with Parkinson's disease most of the complications tend to occur during the first 6 months postoperatively, while in dystonic patients most occur between 12 and 24 months postoperatively.

Abstract
To expose the disc between the 4th and 5th lumbar vertebrae in anterior spinal surgery, left to right retraction of inferior vena cava and aorta is required. This manoeuvre can be complicated by venous haemorrhage that, in most cases, is due to avulsion of the left ascending lumbar vein (ALV) or the left iliolumbar vein (ILV). We dissected 23 embalmed cadavers to assess the factors that contribute to the risk of tearing these two veins during retraction. We describe a triangular region that should help surgeons in identifying the ALV and ILV. This triangle is defined by the lateral border of the common iliac vein, the medial border of the psoas major muscle, and the superior end-plate of the L5 vertebral body. We observed that 3 cm between the termination of the left ALV, or a common stem with the ILV, and the termination of the common iliac vein is the critical distance, less than which the risk of venous avulsion is highest. Although the sample considered is small, our study seems to suggest that male patients tend to have a higher risk of venous avulsion than female patients.

Abstract
One of the most important structures involved in the pathogenesis of occipital headache is the lateral atlanto-axial joint. Previous studies demonstrated that injection of this joint with local anesthetic can alleviate occipital headache, while injection of contrast medium exacerbates it. The aim of our study is to improve the understanding of the nerve supply to the lateral atlanto-axial joint by the C2 nerve elements, in order to determine the optimal target for an anesthetic block of this area. Ten C2 spinal nerves and roots were dissected in five embalmed cadavers with the aid of a 40X microscope and the lateral atlanto-axial joint was shown to be extensively supplied by articular branches of C2 nerve elements (dorsal ganglion, spinal nerve, and ventral ramus). Following our observations on their distribution, we propose a target for local anesthetic injection of the C2 articular branches that is based on reliable landmarks and is easily identifiable at fluoroscopy. We suggest that local anesthetic injection at this target point could be of benefit in the relief of occipital pain due to cervical trauma or degenerative disease involving the lateral atlanto-axial joint.
