RESUMO
Clinical outcomes for patients admitted to hospital during weekend hours have been reported to be poorer than for those admitted during the week. Aneurysmal subarachnoid haemorrhage (aSAH) is a devastating form of haemorrhagic stroke, with a mortality rate greater than 30%. A number of studies have reported higher mortality for patients with aSAH who are admitted during weekend hours. This study evaluates the effect of weekend admission on patients in our unit with aSAH in terms of time to treatment, treatment type, rebleeding rates, functional outcome, and mortality. We analysed a retrospective database of all patients admitted to our tertiary referral centre with aneurysmal subarachnoid haemorrhage between February 2016 and February 2020. Chi-square tests and t-tests were used to compare weekday and weekend demographic and clinical variables. Univariate and multivariate logistic regression analyses were performed to assess for any association between admission during weekend hours and increased neurological morbidity (assessed via Glasgow Outcome Scale at 3 months) and mortality. Of the 571 patients included in this study, 191 were admitted during on-call weekend hours. There were no significant differences found in time to treatment, type of treatment, rebleeding rates, neurological morbidity, or mortality rates between patients admitted during the week and those admitted during weekend hours. Weekend admission was not associated with worsened functional outcome or increased mortality in this cohort. These results suggest that provision of 7-day cover by vascular neurosurgeons and interventional neuroradiologists in high-volume centres could mitigate the weekend effect sometimes reported in the aSAH cohort.

BACKGROUND: Up to 35% of aneurysmal subarachnoid haemorrhage (aSAH) cases may present as poor grade, defined as World Federation of Neurosurgical Societies (WFNS) grades IV and V. In this study, we evaluate functional outcomes and prognostic factors. METHODS: This prospective study included all patients referred to a national, centralized neurosurgical service with a diagnosis of poor-grade aSAH between 01/01/2016 and 31/12/2019. Multivariable logistic regression models were used to estimate probability of poor functional outcomes, defined as a Glasgow Outcome Scale (GOS) of 1-3 at 3 months. RESULTS: Two hundred fifty-seven patients were referred, of whom 116/257 (45.1%) underwent treatment of an aneurysm, with 97/116 (84%) treated within 48 h of referral. Median age was 62 years (IQR 51-69) with a female predominance (167/257, 65%). Untreated patients tended to be older; 123/141 (87%) had WFNS V, 60/141 (45%) unreactive pupils and 21/141 (16%) circulatory arrest. Of all referred patients, poor outcome occurred in 169/230 (73.5%). Unreactive pupils or circulatory arrest conferred a universally poor prognosis, with mortality in 55/56 (98%) and 19/19 (100%), respectively. The risk of a poor outcome was 14.1% (95% CI 4.5-23.6) higher in WFNS V compared with WFNS IV. Age was important in patients without circulatory arrest or unreactive pupils, with risk of a poor outcome increasing by 1.8% per year (95% CI 1-2.7). In patients undergoing aneurysm securement, 48/101 (47.5%) had a poor outcome, with age, rebleeding, vasospasm and cerebrospinal fluid (CSF) diversion being important prognosticators. The addition of serum markers did not add significant discrimination beyond the clinical presentation. CONCLUSIONS: The overall outcomes of WFNS IV and V aSAH remain poor, mainly due to the devastating effects of the original haemorrhage. However, in patients selected for aneurysm securement, good outcomes can be achieved in more than half of patients. Age, pre-intervention rebleeding, vasospasm, and CSF diversion are important prognostic factors.

INTRODUCTION: Papillary thyroid carcinoma (PTC) is the most common form of well-differentiated thyroid carcinoma. Despite its well-differentiated microscopic features, PTC may be minimally or overtly invasive. We present the case of a patient in whom thoracic spinal cord compression was the first presentation of metastatic PTC. CASE REPORT: A 65-year-old woman presented with deteriorating mobility over a 2-month period. Her past history was significant for a right hemithyroidectomy 10 years prior. Examination revealed bilateral lower limb weakness, worse on the right side. Investigations showed a large extradural contrast-enhancing mass at the T7 spinal level. Laminectomy and debulking of this lesion was undertaken. Histopathological examination revealed PTC. The patient proceeded to further treatment with external beam radiotherapy. DISCUSSION: Spinal metastases are an unusual presentation of PTC. Further research into the outcomes for these patients is imperative to bettering our ability to care for these patients through a multi-modality approach.â©.

OBJECTIVE: The economic and logistic burden of screening for hypopituitarism following moderate/severe traumatic brain injury (TBI) is considerable. A key recommendation in published guidelines is to prioritize for screening those patients with symptoms suggestive of pituitary dysfunction. The purpose of this study was to evaluate the utility of targeted screening for hypopituitarism in long-term survivors after moderate/severe TBI using referrals on the basis of symptoms. DESIGN: In group 1 (G1), consecutive, unselected patients were screened from the Irish National Neurosurgery Centre, whereas in group 2 (G2) patients were targeted based on the presence of symptoms suggestive of pituitary dysfunction. PATIENTS: A total of 137 patients (113 male) were systematically screened (G1) and compared to 112 patients (77 male) referred for pituitary evaluation on the basis of suggestive symptoms (G2). MAIN OUTCOME MEASURES: The rate of GH, ACTH, gonadotrophin (GT), TSH and ADH deficiency was compared among groups. RESULTS: Patients referred with menstrual dysfunction had more GH (50% vs 11%, P = 0·001), ACTH (60% vs 14%, P < 0·0001), GT (90% vs 16%, P < 0·0001) deficiency and any pituitary hormone deficit (80% vs 33%, P = 0·003) than G1. Men with symptoms of hypogonadism had more GH (33% vs 11%, P = 0·003), GT (58% vs 16%, P < 0·0001) and TSH (16% vs 1%, P = 0·03) deficiency than G1. Patients with nonspecific symptoms were no more likely to have hypopituitarism than those consecutively screened. CONCLUSIONS: Symptoms of hypogonadism are sufficiently predictive of hypopituitarism to justify screening for hypopituitarism after moderate/severe TBI. Nonspecific symptoms of hypopituitarism are no more predictive than unselected screening.

OBJECTIVE: Chiari I malformation may be treated with foramen magnum decompression (FMD). We aim to describe the symptoms with which patients initially present, and to determine the number and type of complications occurring after FMD for Chiari I malformation. METHODS: Retrospective review of medical records for patients who had FMD performed for Chiari I malformation between January 2009 and December 2011. Post-operative outcomes were recorded and analysed. Patient demographic details and other relevant medical conditions were also noted. RESULTS: Between January 2009 and December 2011, 54 FMDs were performed for Chiari I malformation. Among them, 40(74%) patients were female and 14 patients (26%) were male. The majority of patients (42.6%) were aged 16-39 years and 24.07% of patients were children aged < 16 years. A total of 30(55.6%) patients had documented evidence of a syrinx pre-operatively. 18(33.3%) patients developed complications. Nine of these developed multiple complications while nine had a single problem. One mortality was reported. Ten (18.5%) patients developed hydrocephalus requiring shunting. Two patients developed subdural collections requiring evacuation associated with hydrocephalus. Six (11.1%) patients developed post-operative infections: two CNS infections; one wound infection; and three other infections. CONCLUSIONS: FMD for Chiari I malformation is a procedure which carries risk. In particular, the risk of developing post-operative hydrocephalus requiring permanent shunting is relatively high. ICP monitoring prior to FMD may be required to definitively rule out raised intracranial pressure.

BACKGROUND AND AIMS: International guidelines emphasise the importance of securing ruptured cerebral aneurysms within 48-72 h of ictus. We assessed the timing of treatment of patients with aneurysmal subarachnoid haemorrhage (aSAH) referred to a national neurosurgical centre. MATERIALS AND METHODS: Analysis of a prospective database of patients with aSAH admitted between 1st of February 2016 and 29th of February 2020 was performed. The timing to treatment was expressed in days and analysed in three ways: ictus to treatment, ictus to referral and referral to treatment. ORs with 95% CI were calculated for aneurysm treatment within 24, 48 and 72 h for good grade (WFSN 1-3) and poor grade (WFNS 4-5) cohorts separately. RESULTS: Of a total of 538 patients with aSAH, the aneurysm was secured in 312 (58%) within 24 h and in 398 (74%) within 48 h of ictus. Securing the aneurysm within 48 h of ictus was achieved in 89% (395/444) of patients who were referred within 24 h of ictus, but in only 3.2% (3/94) who were referred > 24 h after ictus. Poor grade patients (WFNS 4-5) were more likely than good grade patients (WFNS 1-3) to be referred to neurosurgery within 48 h of ictus (OR 22.87, 95% CI 3.14-166.49, p = 0.0020) and for their aneurysm to be secured within 48 h (OR 1.78, 95% CI 1.06-2.98, p = 0.0297) of ictus. Ictus to referral delay was highest in WFNS grade 1 patients. CONCLUSIONS: In centres with 7 day per week provision of interventional neuroradiology and vascular neurosurgery, the majority of patients with aSAH can be treated within the timeframes recommended by international guidelines and this applies to all grades of aSAH. However, delays still occur in a significant proportion of patients and this particularly applies to delays in presentation and diagnosis in good grade patients.

OBJECTIVES: Idiopathic intracranial hypertension (IIH) is an uncommon but important cause of headache that can lead to visual loss. This study was undertaken to review our experience in the treatment of IIH by neuronavigation-assisted ventriculoperitoneal (VP) shunts with programmable valves as compared to lumboperitoneal (LP) shunts. METHODS: A retrospective chart review was conducted on 25 patients treated for IIH between 2001 and 2009. Age, sex, clinical presentation, methods of treatment and failure rates were recorded. RESULTS: Seventy-two per cent were treated initially with LP shunts. Failure rate was 11% in this group. Neuronavigation-assisted VP shunts were used to treat 28%. In this group, the failure rate was 14%. CONCLUSION: Our experience indicates that both LP shunts and VP shuts are effective in controlling all the clinical manifestations of IIH in the immediate postoperative period. Failure rates are slightly higher for VP shunts (14%) than LP shunts (11%). However, revision rates are higher with LP shunts (60%) than with VP shunts (30%).

Objectives Lateral temporal bone malignancy remains a challenging rare disease. We report 17 years of multidisciplinary care of these tumors with univariate and multivariate analyses of key prognostic indicators for consideration in contemporary oncological management. Design This is a retrospective cohort study. Setting This is set at a tertiary referral center. Participants All patients presenting with histopathologically newly diagnosed cases of temporal bone malignancy between 2000 and 2017 were included. Main Outcome Measures The main outcome measures are disease-specific and recurrence-free survival rates. Results In this study, 48 cases of temporal bone malignancy were diagnosed. Median age at diagnosis was 69 years (range: 5-88). Fourteen patients were female. Squamous cell carcinoma was the predominant malignancy in 34 cases (71%). Surgical treatment was undertaken in 37 patients. Mean length of follow-up was 32 months (range: 0.7-117). Overall 5-year disease-specific survival was 52.4%, while overall 5-year recurrence-free survival was 53.5%. On univariate analysis, significantly worse survival was seen in females ( p = 0.008), those with distant metastatic disease ( p = 0.041), and in middle ear involvement ( p = 0.012) with no difference for involvement of the external auditory canal ( p = 0.98) or mastoid ( p = 0.78). Only middle ear involvement remained significant on multivariate analysis. Conclusion A wide variety of malignant pathology may present in the temporal bone. Recurrence-free survival is equivalent to international data; however, this figure is low. This emphasizes the need to treat these tumors appropriately with radical resection, where possible, at first presentation. Therefore, multidisciplinary surgical input is recommended. Middle ear involvement was a negative prognosticator for disease-specific and recurrence-free survivals.
RESUMO
Hypophysitis secondary to a ruptured Rathke's cyst is rare. We describe a 53-year-old female who presented with headache and subsequently developed aseptic meningitis and panhypopituitarism. MRI findings and concomitant cardiac arrhythmia and peripheral vasculitis led to a provisional diagnosis of neurosarcoidosis. There were no respiratory manifestations of sarcoidosis. Improvement was noted with empirical treatment with steroids. Pituitary biopsy was undertaken to confirm the diagnosis prior to treatment with long-term immunosuppression for putative neurosarcoidosis. The biopsy revealed lymphocytic hypophysitis secondary to a ruptured Rathke's cyst. This report highlights a rare pathology and the importance of a tissue diagnosis before undertaking non-surgical management of a pituitary mass.

UNLABELLED: A significant number of patients with vestibular schwannomas present atypically, with none of the classical symptoms of unilateral sensorineural hearing loss, tinnitus, and/or dysequilibrium. The aim of this study is to highlight those patients with unusual clinical symptoms. STUDY DESIGN: The clinical data of all patients who presented to the vestibular schwannoma clinic at Beaumont Hospital over the past 12 years was prospectively recorded in a computerized database. This paper reviews the atypical presenting symptoms. RESULTS: Three hundred ninety-eight patients were included in this study. A total of 3.7% of patients presented with atypical symptoms only. CONCLUSION: A significant subgroup, 3.7% in our study, did not present with the audiovestibular symptoms classically associated with vestibular schwannoma. Clinician awareness of the atypical clinical symptoms may lead to earlier detection of these lesions.

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.
RESUMO
BACKGROUND: Bleeding secondary to recurrences of spontaneously obliterated arteriovenous malformations (AVMs) is an extremely rare occurrence. CASE DESCRIPTION: We report a 25-year-old man with cerebellar hemorrhage secondary to a recurrent AVM. His current admission with bleeding from a ruptured cerebellar AVM followed a previous presentation 15 years earlier with the similar clinical picture of AVM rupture within the same vascular territory. At that time, he was managed conservatively with follow-up digital subtraction angiography (DSA) 2 years later, confirming no residuum of the AVM. At the current presentation, he had DSA confirming AVM recurrence. He was managed by complete excision of the AVM via a suboccipital craniotomy. CONCLUSION: This case illustrates the need for long-term imaging follow-up to exclude recanalization even many years after AVM obliteration.

CONTEXT: Hypothalamic-pituitary (HP) dysfunction is common in children treated with cranial radiotherapy (RT) for brain tumors, but there is little known about the risk of HP dysfunction in adults treated with RT for primary nonpituitary brain tumors. OBJECTIVE: The objective was to study the frequency of HP dysfunction in adults after RT for nonpituitary brain tumors. METHOD: We studied 56 adult patients who received external beam RT for primary nonpituitary brain tumors at time intervals of 12-150 months after RT. The control group consisted of 20 RT-naive patients with primary brain tumors. GH and adrenal axes were assessed using the insulin tolerance test or the glucagon stimulation test. Gonadotroph, thyrotroph, and lactotroph function were assessed using baseline blood measurements. The biological effective dose (BED) to the HP axis was calculated in the RT patients. RESULTS: Hypopituitarism was present in 41% of patients. The frequency of GH, ACTH, gonadotropin, and TSH deficiencies, and hyperprolactinemia was 32, 21, 27, 9, and 32%, respectively. Any degree of hypopituitarism and GH deficiency was significantly associated with longer time interval from RT and greater BED. However, gonadotropin deficiency and hyperprolactinemia were only related to BED, whereas ACTH deficiency was only significantly associated with the time interval from RT. One RT-naive patient was GH deficient. CONCLUSION: Adult patients treated with cranial irradiation for primary nonpituitary brain tumors are at high risk of hypopituitarism, which is time and dose dependent. Long-term surveillance and periodic evaluation are needed. We recommend that adult late effect clinics, similar to those for children, should be established.

BACKGROUND: Spontaneous intracerebral hemorrhage (SICH) has a high morbidity and mortality and places a huge significant economic burden on health care and social services. The role of surgery is still controversial as evidenced by wide variation internationally in management of SICH. Traditional surgery for SICH involved open craniotomy with hematoma evacuation. Using available evidence, this article assesses the efficacy of stereotactic-guided evacuation compared with medical treatment. METHODS: A systematic review was performed comparing stereotactic-guided evacuation of SICH with conservative medical management. Eligible studies were identified using a text word search of an electronic journal database for randomized controlled trials. Extracted data outcomes were subjected to meta-analysis with a forest plot. Quality was assessed using Cochrane risk of bias analysis tools. RESULTS: There were 5 studies with 740 patients. There was a nonsignificant reduction in odds ratio (OR) for death at the end of the follow-up period (OR = 0.74, 95% confidence interval = 0.45-1.21) with no significant heterogeneity. Nonsignificant benefits were observed for dependent survival (OR = 2.14, 95% confidence interval = 0.31-0.58). In the subgroup analysis, stereotactic evacuation showed improved outcomes in patients with hematoma volume <50 mL. In this review, the effectiveness of stereotactic evacuation plus subsequent thrombolysis was insignificant (OR = 1.34, 95% confidence interval = 0.57-3.12). CONCLUSIONS: The outcome of patients who had stereotactic-guided evacuation of SICH was not better compared with patients who received medical treatment; however, there was a trend toward better quality of survival and chance of survival in the stereotactic-guided evacuation group. This study identified areas for further research.

Cavernous angiomas of the internal auditory canal are rare lesions. The authors present a case of a 29-year-old lady with multiple infratentorial cavernous angiomas, whose sister had previously undergone surgery for a similar supratentorial lesion. She initially presented with an acute brainstem haematoma, secondary to a pontine cavernous angioma. Three years later she developed progressive right-sided sensorineural hearing loss and facial nerve paresis due to an internal auditory canal lesion. This was removed via the translabyrinthine approach and was found to be a cavernous angioma. This report underlines the multiple and dynamic nature of familial cavernous angiomas, as well as the importance of follow up to determine whether new symptoms are due to the enlargement of known angiomas or the development of new ones. As far as the authors are aware, this is the first report describing a cavernous angioma of the internal auditory canal in the context of familial and multiple infratentorial angiomas.
