Paediatric cerebellar glioblastoma - long-term survival following surgery and adjuvant chemoradiotherapy: A case report and literature review.

Introduction: Paediatric cerebellar glioblastoma is an exceptionally rare clinical entity, with very few cases described in the literature. In the majority of reported cases, prognosis is extremely poor, despite surgical and oncological management. The paucity of data results in lack of consensus as to the optimal management of these patients, with the objective of prolonging survival. Research question: Do patient or tumour characteristics suggest more favourable rates of progression-free survival in paediatric cerebellar glioblastoma? Material and methods: Tumour histopathology plus retrospective molecular analysis of archived samples, as well treatment strategy and patient characteristics of a six-year-old child with cerebellar glioblastoma and prolonged progression-free survival were assessed. Characteristics in the published literature that inferred prolonged survival were identified and compared. Results: Paediatric cerebellar glioblastoma is extremely rare, with only a handful of cases reported over several decades, during which time diagnostic and therapeutic techniques have evolved markedly. Consequently, the scarcity of data with sufficient granularity means that limited conclusions can be drawn. Specific clinical and histopathological factors (i.e. female sex, young age, EGFR negativity and surgical resection plus adjuvant chemoradiotherapy) may indicate a more favourable progression-free survival. Discussion and conclusion: Rates of progression-free survival in this rare condition are generally poor, however, several patient and tumour characteristics may infer more favourable prognosis. As increasingly refined means of diagnosis and characterisation are developed, particularly as a result of advances in molecular analyses, more adjuvant treatment options are likely to come on stream in future.

Safety and feasibility of same-day discharge following lumbar decompression surgery: A systematic review.

Introduction: Lumbar decompression (LD) surgery, with or without discectomy, is a commonly performed surgical procedure. Despite the concept of day-case LD being reported as early as the 1980s, day-case LD is yet to become routine clinical practice. Research question: This systematic review aimed to examine the published literature on the safety and complication rates of day-case LD. Secondary outcome measures, including the economic impact and patient satisfaction of day-case LD, were also examined. Materials and methods: A systematic electronic search was carried out on PubMed, EMBASE and the Cochrane Library between 1999 and January 2022. Studies were screened against predefined inclusion/exclusion criteria with the quality of included studies subsequently being assessed. Results: In total, 15 studies were included in this review. The majority of studies were undertaken in the USA (n â€‹= â€‹8, 53%) and were of a case series design (n â€‹= â€‹9, 60%). Reported complication rates ranged from 0% to 7.8%, with nine studies reporting a complication rate of <4%. Readmission rates ranged from 0% to 7.7%. Seven studies quoted a readmission rate of 0%. Five studies found cost saving benefits of day-case LD in comparison to inpatient LD of up to $27,984 (USD). Patient acceptability of day-case LD was consistently high across the six studies that assessed it. Discussion and conclusion: Day-case LD surgery is a safe and economically efficient surgical option in appropriately selected patients.

Quality of life outcomes after transnasal endoscopic pituitary surgery using the Glasgow Benefit Inventory.

PURPOSE: This study assesses postoperative quality-of-life outcomes via the Glasgow Benefit Inventory (GBI) in patients undergoing transnasal endoscopic pituitary surgery for pituitary adenoma. METHODS: This was a retrospective cohort study in a UK tertiary referral centre. 145 patients who had undergone transnasal endoscopic pituitary surgery for pituitary adenoma over a 6-year period at one institution completed the GBI with at least 3 months' follow up. Patients with prior radiotherapy were excluded. The GBI is a patient-reported outcome measure that assesses post-intervention outcomes in three domains: 'general' functioning, 'social support' and 'physical' functioning. Pre- and post-operative visual loss scores were additionally assessed via a 1-5 Likert scale. GBI scores were assessed alongside these visual loss scores, clinical and surgical parameters and demographics. RESULTS: Mean age was 59.5 years (range 20-87 years) and mean follow up was 36 months. A total of 46 of 145 (31.7%) patients had secreting tumours. The most common primary symptom was visual loss. Mean total score for all patients was positive (+8.4); with 'general' domain score the most positive (+10.5). All patient groups had overall positive, 'general' and 'social support' domain scores. Patients with Cushing's disease reported significantly higher mean total scores (+29.6) than all other groups. Acromegaly (+7.9) and non-functioning adenoma (NFA) groups (+5.2) reported lower mean total scores. 'Physical' domain mean scores were negative for acromegaly and NFA groups. There was statistical significance between a pre- to post-operative improvement in visual score and mean total GBI score (p = 0.02) and mean 'general' domain GBI score (p = 0.02). CONCLUSIONS: These findings can aid preoperative counselling of patients undergoing this surgery. Those with NFA and no anticipated improvement to visual loss symptoms may be advised of possible worsened physical outcomes and of the option to delay the surgery until symptoms are present.

Evaluation of nationwide referral pathways, investigation and treatment of suspected cauda equina syndrome in the United Kingdom.

Purpose: Cauda equina syndrome (CES) is a spinal emergency with clinical symptoms and signs that have low diagnostic accuracy. National guidelines in the United Kingdom (UK) state that all patients should undergo an MRI prior to referral to specialist spinal units and surgery should be performed at the earliest opportunity. We aimed to evaluate the current practice of investigating and treating suspected CES in the UK. Materials and Methods: A retrospective, multicentre observational study of the investigation and management of patients with suspected CES was conducted across the UK, including all patients referred to a spinal unit over 6 months between 1st October 2016 and 31st March 2017. Results: A total of 28 UK spinal units submitted data on 4441 referrals. Over half of referrals were made without any previous imaging (n = 2572, 57.9%). Of all referrals, 695 underwent surgical decompression (15.6%). The majority of referrals were made out-of-hours (n = 2229/3517, 63.4%). Patient location and pre-referral imaging were not associated with time intervals from symptom onset or presentation to decompression. Patients investigated outside of the spinal unit experienced longer time intervals from referral to undergoing the MRI scan. Conclusions: This is the largest known study of the investigation and management of suspected CES. We found that the majority of referrals were made without adequate investigations. Most patients were referred out-of-hours and many were transferred for an MRI without subsequently requiring surgery. Adherence to guidelines would reduce the number of referrals to spinal services by 72% and reduce the number of patient transfers by 79%.

The Pathophysiology of Early Hypotension Following Epinephrine-containing Local Anesthetic Infiltration of the Nasal Mucosa in Patients Undergoing Endoscopic Transsphenoidal Hypophysectomy: A Prospective, Observational Study.

In patients undergoing endoscopic transsphenoidal hypophysectomy, the nasal mucosa is often infiltrated with local anesthetic solutions that contain epinephrine to aid hemostasis. This may, however, result in hemodynamic changes, especially hypotension. We characterized the cardiovascular changes using a LiDCOrapid monitor in 13 patients after the infiltration of 4% articaine containing 1:200,000 epinephrine. Nine (69%) had a >20% decrease in mean arterial pressure at a median time of 116 seconds after the infiltration of articaine with epinephrine. Analysis of the cardiac output data revealed that this was caused by a sustained reduction in systemic vascular resistance. The arterial blood pressure normalized over a period of 60 to 90 seconds secondary to increases in stroke volume and heart rate producing an elevation in cardiac output. Transient hypotension following the infiltration of epinephrine-containing local anesthetics may be caused by epinephrine stimulation of ß2-adrenoceptors producing vasodilation.
