Giant cell arteritis presenting as a stroke in the internal carotid artery territory: a case-based review

Giant cell arteritis (GCA) is a large-vessel vasculitis, typically affecting the aorta and its branches. The involvement of vertebral and internal carotid arteries occurs in a limited number of cases, and stroke as a presenting symptom of GCA is extremely unusual: this subset of the disease has a poor prognosis and rarely responds to immunosuppression.We report the case of a 70-year-old woman, who presented to the Emergency Department for ischemic stroke, which appeared to be the first and only symptom of GCA. The prompt administration of steroids and tocilizumab (TCZ) led to clinical and radiological resolution, with no residual disability at 6-month follow-up.Our case-based review, highlighting the rarity of a large vessel vasculitis presenting only with a cerebrovascular accident, provides new evidence for the efficacy of TCZ even in more unusual varieties of GCA: in these cases, TCZ should be immediately prescribed, in order to prevent mortality and severe long-term morbidity.     

Burosumab for the Treatment of Tumor-Induced Osteomalacia

Tumor-induced osteomalacia (TIO) is caused by phosphaturic mesenchymal tumors producing fibroblast growth factor 23 (FGF23) and is characterized by impaired phosphate metabolism, skeletal health, and quality of life. UX023T-CL201 is an ongoing, open-label, phase 2 study investigating the safety and efficacy of burosumab, a fully human monoclonal antibody that inhibits FGF23, in adults with TIO or cutaneous skeletal hypophosphatemia syndrome (CSHS). Key endpoints were changes in serum phosphorus and osteomalacia assessed by transiliac bone biopsies at week 48. This report focuses on 14 patients with TIO, excluding two diagnosed with X-linked hypophosphatemia post-enrollment and one with CSHS. Serum phosphorus increased from baseline (0.52 mmol/L) and was maintained after dose titration from week 22 (0.91 mmol/L) to week 144 (0.82 mmol/L, p < 0.0001). Most measures of osteomalacia were improved at week 48: osteoid volume/bone, osteoid thickness, and mineralization lag time decreased; osteoid surface/bone surface showed no change. Of 249 fractures/pseudofractures detected across 14 patients at baseline, 33% were fully healed and 13% were partially healed at week 144. Patients reported a reduction in pain and fatigue and an increase in physical health. Two patients discontinued: one to treat an adverse event (AE) of neoplasm progression and one failed to meet dosing criteria (receiving minimal burosumab). Sixteen serious AEs occurred in seven patients, and there was one death; all serious AEs were considered unrelated to treatment. Nine patients had 16 treatment-related AEs; all were mild to moderate in severity. In adults with TIO, burosumab exhibited an acceptable safety profile and was associated with improvements in phosphate metabolism and osteomalacia. © 2020 The Authors.

The combination cytology/epichek test in non muscle invasive bladder carcinoma follow-up: Effective tool or useless expence?

ObjectiveTo identify in which cases after cytological diagnosis, the Bladder EpiCheck test could represent an effective tool in non-muscle invasive bladder carcinoma or an useless expence.Materials and methods375 patients diagnosed with non-muscle invasive bladder cancer, 269 with high grade urothelial carcinoma and 106 with carcinoma in situ, were treated and followed for 1 year. The treatment was an intravesical instillation of Bacillus Calmette-Guerin in 305 patients and Mitomycin-C in 70 patients.During the follow-up patients were evaluated by voided urine cytology and white-light cystoscopy, according to the European Association of Urology Guidelines. Bladder EpiCheck test was performed together with cytology in all cases.ResultsAnalyzing Bladder Epicheck results for each category defined by the Paris System for Reporting Urinary Cytology, we found that the Episcore >60 correlates with histological diagnosis of high grade urothelial carcinoma (HGUC) in atypical urothelial cells and Suspicious for High Grade Urothelial Carcinoma (P = 0.0002 Odds Ratio 0.05926 95% Confidence Interval from 0.01127 to 0.3116 and P = 0.0009 Odds Ratio 0.0315595% Confidence Interval from 0.001683 to 0.5914, Fisher's exact test, respectively), while in Negative for high grade urothelial carcinoma and HGUC patients Episcore is not helpful to identify cases with histological diagnosis of HGUC (P = 0.101 and P = 0.58 Fisher's exact test, respectively). Considering an Episcore ≥ 90 in the HGUC cytological group, this seems not to be correlated with a histological diagnosis of HGUC (P = 0.090 Fisher's exact test).ConclusionsCytology and Bladder EpiCheck test in combination may have the potential to reduce cystoscopies in the follow-up of non-muscle invasive bladder cancer only for cytological diagnoses of atypical urothelial cells and Suspicious for High Grade Urothelial Carcinoma . Moreover, in patients with a cytological diagnosis of Negative for high grade urothelial carcinoma or HGUC, cytology alone seems to be safe and cost-effective.     

Patients undergoing surgery for lumbar degenerative spinal disorders favor smartphone-based objective self-assessment over paper-based patient-reported outcome measures

Background ContextSmartphone-based applications enable new prospects to monitor symptoms and assess functional outcome in patients with lumbar degenerative spinal disorders. However, little is known regarding patient acceptance and preference towards new modes of digital objective outcome assessment.PurposeTo assess patient preference of an objective smartphone-based outcome measure compared to conventional paper-based subjective methods of outcome assessment.Study designProspective observational cohort study.Patient sampleFourty-nine consecutive patients undergoing surgery for lumbar degenerative spinal disorder.Outcome measuresPatients completed a preference survey to assess different methods of outcome assessment. A 5-level Likert scale ranged from strong disagreement (2 points) over neutral (6 points) to strong agreement (10 points) was used.MethodsPatients self-determined their objective functional impairment using the 6-minute Walking Test application (6WT-app) and completed a set of paper-based patient-reported outcome measures (PROMs) before and 6 weeks after surgery. Patients were then asked to rate the methods of outcome assessment in terms of suitability, convenience, and responsiveness to their symptoms.ResultsThe majority of patients considered the 6WT-app a suitable instrument (median 8.0, interquartile range [IQR] 4.0). Patients found the 6WT more convenient (median 10.0, IQR 2.0) than the Zurich Claudication Questionnaire (ZCQ; median 8.0, IQR 4.0, p=.019) and Core Outcome Measure Index (COMI; median 8.0, IQR 4.0, p=.007). There was good agreement that the 6WT-app detects change in physical performance (8.0, IQR 4.0). 78 % of patients considered the 6WT superior in detecting differences in symptoms (vs. 22% for PROMs). Seventy-six percent of patients would select the 6WT over the other, 18% the ZCQ and 6% the COMI. Eighty-two percent of patients indicated their preference to use a smartphone app for the assessment and monitoring of their spine-related symptoms in the future.ConclusionsPatients included in this study favored the smartphone-based evaluation of objective functional impairment over paper-based PROMs. Involving patients more actively by means of digital technology may increase patient compliance and satisfaction as well as diagnostic accuracy.
