RESUMO
Introduction: Studies report rates of treatment-requiring postoperative intracranial haemorrhage after craniotomy around 1-2%, but do not distinguish between supratentorial and posterior fossa operations. Reports about intracranial haemorrhages' temporal occurrence show conflicting results. Recommendations for duration of postoperative monitoring vary. Research question: To determine the rate, temporal pattern and clinical presentation of reoperation-requiring postoperative intracranial posterior fossa haemorrhage. Material and methods: This retrospective case-series identified cases operated with posterior fossa craniotomy or craniectomy between January 1, 2007 and December 31, 2021 by an electronic search in the patient administrative database, and collected data about patient- and treatment-characteristics, postoperative monitoring, and the occurrence of haemorrhagic and other serious postoperative complications. Results: We included 62 (n = 34, 55% women) cases with mean age 48 (interquartile range 50) years operated for tumours (n = 34, 55%), Chiari malformations (n = 18, 29%), ischemic stroke (n = 6, 10%) and other lesions (n = 3, 5%). One (2%) 66-year-old woman who was a daily smoker operated with decompressive craniectomy and infarct resection, developed a reoperation-requiring postoperative intracranial haemorrhage after 25.5 h. In four (6%) cases, other serious complications requiring reoperation or transfer from the post anaesthesia care unit or regular bed wards to the intensive care unit occurred after 0.5, 6, 9 and 54 h, respectively. Discussion and conclusion: Treatment-requiring postoperative intracranial haemorrhage and other serious complications after posterior fossa craniotomies occur over a wide timespan and are difficult to capture with a standardized postoperative monitoring time. This indicates that the duration of monitoring should be individualized based on assessment of risk factors.
RESUMO
PURPOSE: Standard surgical treatment for symptomatic cervical disc disease has been discectomy and fusion, but the use of arthroplasty, designed to preserve motion, has increased, and most studies report clinical outcome in its favor. Few of these trials, however, blinded the patients. We, therefore, conducted the Norwegian Cervical Arthroplasty Trial, and present 2-year clinical outcome after arthroplasty or fusion. METHODS: This multicenter trial included 136 patients with single-level cervical disc disease. The patients were randomized to arthroplasty or fusion, and blinded to the treatment modality. The surgical team was blinded to randomization until nerve root decompression was completed. Primary outcome was the self-rated Neck Disability Index. Secondary outcomes were the numeric rating scale for pain and quality of life questionnaires Short Form-36 and EuroQol-5Dimension-3 Level. RESULTS: There was a significant improvement in the primary and all secondary outcomes from baseline to 2-year follow-up for both arthroplasty and fusion (P < 0.001), and no observed significant between-group differences at any follow-up times. However, linear mixed model analyses, correcting for baseline values, dropouts and missing data, revealed a difference in Neck Disability Index (P = 0.049), and arm pain (P = 0.027) in favor of fusion at 2 years. The duration of surgery was longer (P < 0.001), and the frequency of reoperations higher (P = 0.029) with arthroplasty. CONCLUSION: The present study showed excellent clinical results and no significant difference between treatments at any scheduled follow-up. However, the rate of index level reoperations was higher and the duration of surgery longer with arthroplasty. TRIAL REGISTRATION: http://www.clinicaltrials.gov NCT 00735176.19.

BACKGROUND: Spondylitis in the upper cervical spine can have an insidious onset, with symptoms mimicking low-grade infections or common musculoskeletal disorders. Some patients have neurological symptoms, and if untreated, the outcome may be fatal. CASE PRESENTATION: A woman in her fifties had general malaise, weight loss and neck pain over 6-8 weeks. Her sedimentation rate was elevated, and she developed bulbar symptoms. Biopsy and culture samples were harvested endoscopically from the prevertebral area in the C1-C2 region, and confirmed our preliminary diagnosis of localised infection. She was treated with high-dose antibiotics and rigid collar immobilisation until stability of the cervical spine was ascertained. INTERPRETATION: It is difficult to make a differential diagnosis between spondylitis, rheumatoid inflammation and malignancy in the upper cervical spine. Adequate histologic and bacterial culture samples must if possible be obtained from the prevertebral area. This is best achieved transnasally or transorally, under endoscopic and radiological guidance. The neck must be stabilised and patients must have long-term antibiotic treatment followed by permanent neck fixation if indicated.

Fabry disease (FD) is a lysosomal storage disorder that is associated with marked cerebrovascular disease. Conventional MRI shows a progressive load of white matter lesions (WMLs) due to cerebral vasculopathy in the course of FD. To quantify brain structural changes in clinically affected male and female patients with FD we performed a prospective Diffusion-Tensor Imaging (DTI) study in 27 adult Fabry patients (13m, 14f) and 21 age-matched controls (12 m, 9f). Global Mean Diffusivity (MD) was increased in FD (P = 0.003) whereas global Fractional Anisotropy (FA) did not differ significantly between FD and controls. Even FD patients without significant WMLs (9m, 9f) showed increased global MD (P = 0.004). Regions of interest with significant MD elevations were located in the frontal, parietal and temporal white matter. No differences of thalamic and hippocampal DTI measurements could be detected between FD and controls. DTI parameters did not differ between male and female patients. The data provide the first evidence of a pattern of marked structural brain tissue alterations in adult FD male and female patients even without WMLs. DTI seems to be an appropriate diagnostic tool to quantify brain tissue integrity in FD. Moreover, this method could be favorable for longitudinal assessment of brain structure alterations in FD, and for monitoring the cerebral effects of enzyme replacement therapy.

BACKGROUND: A national survey in 1996 showed insufficient routines for management of patients with mild head injuries in Norwegian hospitals. Since then, the Scandinavian Guidelines for Management of Mild Head Injuries have been published. METHODS: A cross-sectional questionnaire survey of management practice was performed in all 59 hospitals in 2002. We compared the results with figures from 1996 and evaluated guideline compliance. RESULTS: The proportion of noncompliant hospitals was reduced (p = 0.02) from 52% to 31%. The proportion assessing the patient's level of consciousness according to the Glasgow Coma Scale increased (p = 0.001) from 49% to 80%. The proportion requiring a normal computed tomographic scan if a patient with a history of loss of consciousness was to be sent home from the accident and emergency department increased (p < 0.001) from 1 (2%) to 13 (19%). CONCLUSION: The Scandinavian Guidelines for Management of Mild Head Injuries have had a significant impact on management practice in Norwegian hospitals.
