CSF Rhinorrhea After Endonasal Intervention to the Skull Base (CRANIAL) — Part 2:Impact of COVID-19
Background During the pandemic, there has been a concern about the increased risk of perioperative mortality for patients with COVID-19, and the transmission risk to healthcare workers, particularly during endonasal neurosurgical operations. The Pituitary Society produced recommendations to guide management during this era. We sought to assess contemporary neurosurgical practice and the impact of COVID-19. Methods A multicentre, prospective, observational cohort study was conducted at twelve tertiary neurosurgical units (UK and Ireland). Data were collected from March 23rd-July 31st, 2020 inclusive. Data points collected were patient demographics, pre-operative COVID-19 testing, intra-operative operative modifications, and 30-day COVID infection rates. Results 124 patients were included. 116 patients (n=116/124, 94%) underwent COVID-19 testing pre-operatively (TSA: 97/105, 92%; EEA: 19/19, 100%). One patient (n=1/115, 1%) tested positively for COVID-19 pre-operatively, requiring a delay of operation until the infection was confirmed as resolved. Asides from transient diabetes insipidus; no other complications were reported for this case. All theatre staff wore at least level 2 PPE. Adaptations to surgical techniques included minimising drilling, draping modifications, and using nasal iodine wash. At 30 days postoperatively, there was no evidence of COVID infection (symptoms or on formal testing) in our cohort, and no mortality. Conclusions Preoperative screening protocols and operative modifications have facilitated endonasal neurosurgery during the COVID-19 pandemic, with Pituitary Society guidelines followed for the majority of these operations. There was no evidence of COVID infection in our cohort, and no mortality, supporting the use of risk mitigation strategies to continue endonasal neurosurgery in subsequent pandemic waves
Rationale and recommendations on decolonising the pedagogy and curriculum of the Law School at the University of Exeter
This is the final version. Available on open access from Routledge via the DOI in this recordThis report outlines the rationale behind and recommendations on the steps that need to be taken towards decolonising the Law School's pedagogy and curriculum. It concludes a two-year process of research and discussions involving a joint effort between staff and students. A rationale for a change in approach to both pedagogy and curriculum is presented together with recommendations and practical examples of how this might be achieved in modular teaching in the Law School
CSF Rhinorrhoea After Endonasal Intervention to the Skull Base (CRANIAL) - Part 1: Multicenter Pilot Study
Background:
CRANIAL (CSF Rhinorrhoea After Endonasal Intervention to the Skull Base) is a prospective, multicentre observational study seeking to determine: (1) the scope of skull base repair methods used; and (2) corresponding rates of postoperative CSF rhinorrhoea in endonasal transsphenoidal (TSA) expanded endonasal approaches (EEA) for skull base tumours. We sought to pilot the project - assessing the feasibility and acceptability by gathering preliminary data. /
Methods:
A prospective, observational cohort pilot study was carried out at twelve tertiary UK neurosurgical units. Feedback regarding project positives and challenges were qualitatively analysed. /
Results:
187 cases were included, 159 TSA (85%) and 28 EEA (15%). The most common pathologies included: pituitary adenomas (n=141/187), craniopharyngiomas (n=13/187) and skull-base meningiomas (n=4/187). The most common skull base repair techniques used were tissue glues (n=132/187, most commonly Tisseel®), grafts (n=94/187, most commonly fat autograft or Spongostan™) and vascularised flaps (n=51/187, most commonly nasoseptal). These repairs were most frequently supported by nasal packs (n=125/187) and lumbar drains (n=22/187). Biochemically-confirmed CSF rhinorrhoea occurred in 6/159 (3.8%) TSA and 2/28 (7.1%) EEA. Four TSA (3%) and two EEA (7%) cases required operative management for CSF rhinorrhoea (CSF diversion or direct repair). Qualitative feedback was largely positive (themes included: user-friendly and efficient data collection, strong support from senior team members) demonstrating acceptability. /
Conclusions:
Our pilot experience highlights the acceptability and feasibility of CRANIAL. There is a precedent for multicentre dissemination of this project, in order to establish a benchmark of contemporary skull base neurosurgery practice, particularly with respect to EEA cases

Identifying the deficiencies of current diagnostic criteria for neurofibromatosis 2 using databases of 2777 individuals with molecular testing
Purpose
We have evaluated deficiencies in existing diagnostic criteria for neurofibromatosis 2 (NF2).
Methods
Two large databases of individuals fulfilling NF2 criteria (n = 1361) and those tested for NF2 variants with criteria short of diagnosis (n = 1416) were interrogated. We assessed the proportions meeting each diagnostic criterion with constitutional or mosaic NF2 variants and the positive predictive value (PPV) with regard to definite diagnosis.
Results
There was no evidence for usefulness of old criteria “glioma“ or “neurofibroma.” “Ependymoma” had 100% PPV and high levels of confirmed NF2 diagnosis (67.7%). Those with bilateral vestibular schwannoma (VS) alone aged ≥60 years had the lowest confirmation rate (6.6%) and reduced PPV (80%). Siblings as a first-degree relative, without an affected parent, had 0% PPV. All three individuals with unilateral VS and an affected sibling were proven not to have NF2. The biggest overlap was with LZTR1-associated schwannomatosis. In this category, seven individuals with unilateral VS plus ≥2 nondermal schwannomas reduced PPV to 67%.
Conclusions
The present study confirms important deficiencies in NF2 diagnostic criteria. The term “glioma” should be dropped and replaced by “ependymoma.” Similarly “neurofibroma” should be removed. Dropping “sibling” from first-degree relatives should be considered and testing of LZTR1 should be recommended for unilateral VS
Prevalence of wife beating in Jordanian refugee camps: reports by men and women
Wife beating, the most widespread form of domestic violence, has adverse consequences on the health and wellbeing of women and is a major cause of disability and death in many countries.1 In the past few years, it has been widely reported in developing countries’ contexts,2 where patriarchal family norms are common.3 In the Middle East, patriarchal gender relations reinforced by traditional cultural, legal, and perhaps religious legacies may have directly or indirectly influenced the persistence of violence against women. In fact, intimate partner violence is not considered a criminal act in many Arab countries. Available studies provide only limited insight into the prevalence of domestic violence in a patriarchal context. Furthermore, most previous studies of wife beating from developing countries focused on female respondents, thus neglecting men, the perpetrators of violence.Using data from independent samples of married men and women, this study investigated the prevalence of wife beating in the Palestinian refugee camps of Jordan. Specifically, the study aimed to examine the similarity between men’s self reports of violence and women’s reports of being subjected to domestic violence. The focus was on lifetime physical domestic violence against women, but estimates of current (past year) beating as well as injuries resulting from beating were also described
The airway in inhalational injury: diagnosis and management.
It is estimated that 13.000 to 22.000 individuals suffer from inhalational burns each year in the United States alone. Despite these high numbers, inhalational burns remain a major challenge to otolaryngologists. In this paper, a review of literature is presented in order to provide otolaryngologists with a systematic approach to patients with inhalational burns to optimize treatment, cost, morbidity and, most importantly, mortality. For this purpose, a broad PubMed search was conducted. The available literature was found to highlight the importance of airway management in terms of the timing of intubation, method of intubation, trachea-esophageal (TE) fistula formation and TE rupture. It also emphasizes the importance of carbon monoxide intoxication and prompt correction. Drugs such as heparin sulfate, N-acetylcysteine and albuterol have been proven to help in the treatment of patients with inhalational burns, and more research is currently underway with the purpose of developing chelating drugs that scavenge the toxic substances in the smoke before they can damage the airway
