RESUMEN
We present the case of a teenaged boy who attended our Ear, Nose and Throat Emergency clinic with a left-sided lower motor neuron (LMN) facial nerve paralysis associated with sensory loss in the distribution of the ophthalmic (V1) and maxillary (V2) divisions of the trigeminal nerve. This happened 3 days following a first dose of the Pfizer-BioNTech BNT162b2 vaccine. He had a House-Brackmann grade V facial palsy, with marked inability to close the left eye. He was treated with a 10-day course of oral steroids and referred to ophthalmology for eye care. He had an MRI scan of the head, which revealed no space occupying lesions or other abnormalities. Over the 6-week period of follow-up, the patient's V1 and V2 sensation gradually resolved, along with improvement of his LMN facial nerve palsy to House-Brackmann grade 3. Despite the potential temporal relationship, it is not possible to establish a causal relationship between the patient's symptoms and the Pfizer-BioNTech BNT162b2 vaccine, thus further research is required.

BACKGROUND: Interactive case-based tutorials represent a well-established method of improving House Officer learning. There has been little research on how tutorials of this kind can be improved, and whether their use changes practice. AIM: Our study aims to assess whether our eLearning tutorial on IV fluid and electrolyte prescribing improves the underlying knowledge base and confidence of participating House Officers, with regards to fluid and electrolyte balance physiology and prescribing. METHOD: An interactive eLearning module with core information on fluid and electrolyte prescribing and associated cases with questions and answers was created and distributed to participating House Officers in the 2019-2020 cohort nationwide. Participants were asked to complete pre-eLearning and post-eLearning questionnaires as well as a feedback survey to assess the efficacy of the module. RESULTS: Forty-nine House Officers completed the eLearning module and associated questionnaires. A majority of participants (69.3%) reported their previous teaching on fluid and electrolyte management as "very poor", "poor" or "mediocre". The average score for the pre-eLearning knowledge test was 75%, compared to a score of 97% for the post-eLearning knowledge test, resulting in a 22% increase in correct answers (p < 0.001). We found an increase of 53% in feeling "confident" or "very confident" in assessing and managing fluid requirements, and an increase of 57.1% in feeling "confident" or "very confident" in managing electrolyte requirements after undertaking the eLearning module. CONCLUSION: An interactive eLearning tutorial with real-world applications provides an effective, low-cost intervention that can improve confidence and skill in prescribing IV fluids.

BACKGROUND: Prostate cancer (PCa) represents a significant healthcare problem. The critical clinical question is the need for a biopsy. Accurate risk stratification of patients before a biopsy can allow for individualised risk stratification thus improving clinical decision making. This study aims to build a risk calculator to inform the need for a prostate biopsy. METHODS: Using the clinical information of 4801 patients an Irish Prostate Cancer Risk Calculator (IPRC) for diagnosis of PCa and high grade (Gleason ≥7) was created using a binary regression model including age, digital rectal examination, family history of PCa, negative prior biopsy and Prostate-specific antigen (PSA) level as risk factors. The discrimination ability of the risk calculator is internally validated using cross validation to reduce overfitting, and its performance compared with PSA and the American risk calculator (PCPT), Prostate Biopsy Collaborative Group (PBCG) and European risk calculator (ERSPC) using various performance outcome summaries. In a subgroup of 2970 patients, prostate volume was included. Separate risk calculators including the prostate volume (IPRCv) for the diagnosis of PCa (and high-grade PCa) was created. RESULTS: IPRC area under the curve (AUC) for the prediction of PCa and high-grade PCa was 0.6741 (95% CI, 0.6591 to 0.6890) and 0.7214 (95% CI, 0.7018 to 0.7409) respectively. This significantly outperforms the predictive ability of cancer detection for PSA (0.5948), PCPT (0.6304), PBCG (0.6528) and ERSPC (0.6502) risk calculators; and also, for detecting high-grade cancer for PSA (0.6623) and PCPT (0.6804) but there was no significant improvement for PBCG (0.7185) and ERSPC (0.7140). The inclusion of prostate volume into the risk calculator significantly improved the AUC for cancer detection (AUC = 0.7298; 95% CI, 0.7119 to 0.7478), but not for high-grade cancer (AUC = 0.7256; 95% CI, 0.7017 to 0.7495). The risk calculator also demonstrated an increased net benefit on decision curve analysis. CONCLUSION: The risk calculator developed has advantages over prior risk stratification of prostate cancer patients before the biopsy. It will reduce the number of men requiring a biopsy and their exposure to its side effects. The interactive tools developed are beneficial to translate the risk calculator into practice and allows for clarity in the clinical recommendations.

BACKGROUND: Fluid and electrolyte management for hospital inpatients has been identified by multiple reports to be suboptimal, with delegation of this task to the most junior members of a medical team, Foundation Year One (FY1) doctors, also known as interns or house officers, being identified as a contributing factor. METHODS: An online survey was distributed nationally via social media to FY1 doctors between 21st August 2018 and 19th September 2018. Questions focused around cohort characteristics, team behaviours around fluid and electrolyte prescribing, as well as teaching and knowledge. RESULTS: Two hundred eighty-six doctors participated. 67.13% knew the daily water requirement of a healthy adult. 58.39 and 79.72% knew the daily requirements of potassium and sodium, respectively. 41.26 and 33.57% knew the potassium and sodium composition of Hartmann's solution (1 L), respectively, with only 31.12% of candidates knowing the correct sodium content of 1 L of normal saline 0.9%. FY1 doctors were the principle prescribers of fluid therapy (97.55%); senior house officers, registrars, and consultants were only actively involved in the process 51.75, 20.98, and 5.59% of the time, respectively. 30.77 and 23.43% of FY1s received guidelines and/or teaching on the topic within their firms or as part of their foundation teaching, respectively. At undergraduate level, 52.44% of doctors reported the teaching to be "neither poor or good," "poor," or "very poor." CONCLUSION: The principle knowledge base underlying fluid and electrolyte management is still poorly understood by FY1 doctors, with poor teaching of the subject at both undergraduate and post-graduate level potentially contributing.

INTRODUCTION: The medical elective is a common component of undergraduate medical education in the UK and Ireland. These are often undertaken in varied hospitals and countries across the world, most of which are not related to their parent institutions, in order to explore specialties and regions of interest. However experiences are varied, with goals not always established beforehand, or indeed reached, when present. METHODS: Using a novel 20-item, self-administered questionnaire distributed via social media to 436 medical students and doctors in the UK and Republic of Ireland, we sought to delineate common elective experiences and establish what procedures and clinical scenarios medical students commonly undertake and manage during their medical electives, in order to ascertain their confidence level with each of these tasks at the time of their medical electives. We also looked to determine if there are any adverse effects or events related to these situations. Following this, we developed a simulation-based course to address knowledge and skill gaps identified in the above fields. This course was delivered to two groups of medical students from St George's University London and King's College London medical schools by the same faculty over two separate afternoons. RESULTS: We found that a significant proportion of medical students feel pressured to perform skills, which are beyond their competence level during their elective placements, putting both patient and student safety at risk. Our simulation course was successful in significantly improving key technical and non-technical skills, which would be useful for students during their medical electives.

OBJECTIVE: To assess the quality of life (QoL) in a representative sample of patients with vestibular schwannoma and to ascertain the differences in outcomes associated with distinct management strategies. PATIENTS AND METHODS: Patients with vestibular schwannoma attending a tertiary referral center were asked to complete the Functional Assessment of Chronic Illness Therapy-Brain Questionnaire, which assesses QoL in 5 domains: physical, social, emotional and functional, and a brain cancer-specific domain. Results were analyzed in the overall cohort and in surgery, stereotactic radiosurgery, and conservative management subgroups. The relationship between patient clinical characteristics and QoL outcome also was analyzed by univariable and multivariable logistic regression. RESULTS: There were 83 survey respondents with an average age of participants of 57 years and a mean follow-up of 4.9 years. QoL was statistically significantly lower in the surgery subgroup within the Physical QoL domain (P = 0.039); however, there was no significant difference in overall QoL between the 3 subgroups of surgery, radiosurgery, and conservative management (P = 0.17). A poor QoL outcome was associated with the number of symptoms at diagnosis, greater tumor size, and a surgical management strategy. CONCLUSIONS: The QoL within this patient cohort was extremely variable in each management group, mirroring the heterogeneous natural history of this disease process. QoL in patients with vestibular schwannoma cannot be predicted based on management strategy alone, but a poor QoL outcome is more likely in patients with larger, symptomatic tumors that are treated surgically.

Introduction The objective of this study was to describe the most common clinical features associated with an acoustic neuroma diagnosis and to identify those features associated with larger tumour size at initial diagnosis. Methods The clinical information of 945 consecutive patients diagnosed with acoustic neuroma at a single centre between 1992 and 2015 was analysed. Clinical features were examined and the relationship between these features and tumour size (>2.5 cm) was analysed using descriptive statistics and logistic regression analysis. Statistical analysis was performed in R version 3.1.1. Results The most common presenting symptom was a unilateral hearing loss in 752 patients (80%), with a progressive pattern in 90% of these cases. The second most common presenting symptom was unilateral tinnitus, accounting for 6.3%, while ataxia, vertigo and headache accounted for 3.8%, 3.4% and 2%, respectively. The diagnosis of acoustic neuroma was an incidental finding in 20 patients (2.1%). Temporal analysis demonstrated a downward trend in the number of patients presenting with hearing loss and an increased proportion of patients presenting with other symptoms. On multivariate analysis, larger tumour size was associated with abnormal tandem gait (odds ratio 8.9, p=0.02), subjective facial weakness (odds ratio 5.3, p< 0.001), abnormal facial sensation on examination (odds ratio 3.0, p=0.03) and headache (odds ratio 2.6, p< 0.001). Conclusion The majority of patients with acoustic neuroma present with the classic, progressive, unilateral hearing loss. However, the pattern of presentation in acoustic neuroma patients is changing. Features in the history indicative of a larger tumour are headaches and subjective facial weakness, whilst concerning features on examination are abnormal tandem gait and altered facial sensation.
RESUMEN
OBJECTIVE: To analyse the performance of the Prostate Cancer Prevention Trial Risk Calculator (PCPT-RC) and two iterations of the European Randomised Study of Screening for Prostate Cancer (ERSPC) Risk Calculator, one of which incorporates prostate volume (ERSPC-RC) and the other of which incorporates prostate volume and the prostate health index (PHI) in a referral population (ERSPC-PHI). PATIENTS AND METHODS: The risk of prostate cancer (PCa) and significant PCa (Gleason score ≥7) in 2001 patients from six tertiary referral centres was calculated according to the PCPT-RC and ERSPC-RC formulae. The calculators' predictions were analysed using the area under the receiver-operating characteristic curve (AUC), calibration plots, Hosmer-Lemeshow test for goodness of fit and decision-curve analysis. In a subset of 222 patients for whom the PHI score was available, each patient's risk was calculated as per the ERSPC-RC and ERSPC-PHI risk calculators. RESULTS: The ERSPC-RC outperformed the PCPT-RC in the prediction of PCa, with an AUC of 0.71 compared with 0.64, and also outperformed the PCPT-RC in the prediction of significant PCa (P<0.001), with an AUC of 0.74 compared with 0.69. The ERSPC-RC was found to have improved calibration in this cohort and was associated with a greater net benefit on decision-curve analysis for both PCa and significant PCa. The performance of the ERSPC-RC was further improved through the addition of the PHI score in a subset of 222 patients. The AUCs of the ERSPC-PHI were 0.76 and 0.78 for PCa and significant PCa prediction, respectively, in comparison with AUC values of 0.72 in the prediction of both PCa and significant PCa for the ERSPC-RC (P = 0.12 and P = 0.04, respectively). The ERSPC-PHI risk calculator was well calibrated in this cohort and had an increase in net benefit over that of the ERSPC-RC. CONCLUSIONS: The performance of the risk calculators in the present cohort shows that the ERSPC-RC is a superior tool in the prediction of PCa; however the performance of the ERSPC-RC in this population does not yet warrant its use in clinical practice. The incorporation of the PHI score into the ERSPC-PHI risk calculator allowed each patient's risk to be more accurately quantified. Individual patient risk calculation using the ERSPC-PHI risk calculator can be undertaken in order to allow a systematic approach to patient risk stratification and to aid in the diagnosis of PCa.

Malignant melanoma is a common skin neoplasm bearing poor prognosis when presenting with metastases. Rarely melanoma metastases present without an identifiable primary cutaneous lesion despite exhaustive workup. We describe the case of a solitary lung metastasis in a patient with neurofibromatosis type 1 without an identifiable primary tumour. The rapid progression of this malignant neoplasm that led to the patient's death within 1 year is described.
