RESUMEN
BACKGROUND: Cervical Artery Dissection is an important cause of stroke in the young. Data on incidence and associations of recurrence in patients with cervical artery dissection are lacking. Increased Vertebral Artery Tortuosity Index has been reported in patients with cervical artery dissection and associated with earlier age of arterial dissection in patients with connective tissue disease. OBJECTIVE: To test the hypothesis that increased vertebral artery tortuosity is associated with recurrent cervical artery dissection. METHODS: We reviewed data from a single-center registry of cervical artery dissection patients enrolled between 2011-2021. CT angiography was reviewed for neck length, vertebral artery dominance, and vertebral artery tortuosity index. Incidence rate of recurrent dissection was calculated using Poisson regression. Differences between groups were analyzed using the Kruskal-Wallis rank sum test and Fisher's exact test. RESULTS: The cohort included 155 patients: women (56%), mean (SD) age 42 (±10) years, and 116 single and 39 multiple artery dissections. Eleven (7.1%) had a recurrence with an incidence rate (95% CI) of 1.91 (1.06, 3.44) per 100 person-years. Vertebral artery tortuosity did not differ significantly between single and recurrent groups (median (IQR) 46.81 (40.85, 53.91) vs 44.97 (40.68, 50.62) p = 0.388). Morphometric characteristics of height, neck length, and BMI were not associated with recurrence. There was no difference in vertebral artery tortuosity by dissection location (carotid vs vertebral). CONCLUSION: In this single center cohort of patients with cervical artery dissection, there was no difference in VTI between single and recurrent groups.

BACKGROUND: In May 2012, the US Preventive Services Task Force assigned prostate-specific antigen-based screening a grade D recommendation, advising against screening at any age. Our objective was to compare prostate cancer characteristics pre- and post-recommendation with an adjusted analysis of our data and a pooled analysis including other primary data sources. METHODS: We identified all incident prostate cancer diagnoses at our institution from 2007 to 2016. Multivariable log binomial regression was used to determine the relative risk (RR) of metastasis at diagnosis, ≥Gleason Group 4, and high D'Amico risk disease pre- versus post-recommendation. The meta-analysis included primary data studies evaluating these outcomes. RESULTS: At our institution, 287 (44.6%) and 224 (48.8%) patients were diagnosed in the pre- and post-cohorts. The RR of metastatic disease at diagnosis did not differ between groups (p = 0.224), nor did the risk of high D'Amico category disease (p = 0.089). The risk of ≥Gleason Group 4 was 1.58 times higher post-recommendation (p = 0.007). The pooled risk of ≥Gleason Group 4 disease was 1.5 (p < 0.001) post-recommendation and was 1.29 (p = 0.006) for high D'Amico risk disease. CONCLUSIONS: While the number of metastatic cases did not differ after the recommendation, the risk of high-grade cancers increased at both a local and aggregated level.

OBJECTIVE: To identify the incidence of radiation-induced urologic complication requiring procedural intervention following high-dose radiotherapy for cervical carcinoma, and to identify predictors of complication occurrence. MATERIALS AND METHODS: We performed a retrospective chart review of cervical cancer patients undergoing radiotherapy with primary focus on procedural complications (Clavien-Dindo ≥ III). Clinical data were collected including radiation dose, procedure performed, timing of complication, and need for additional procedures. Univariate and multivariate logistic regression modeling was performed to assess predictive value of demographic and clinical variables. RESULTS: A total of 126 patients with FIGO stage 1A2-4B cervical cancer were included in study analysis, with 18 patients experiencing procedural complication (14.3%). A total of 22 complications were identified, representing an average of 1.2 complications per patient with complication. The most common complications were ureteral stricture and radiation cystitis. The most common nononcologic procedures performed in the treatment of these complications were ureteral stenting, percutaneous nephrostomy tube placement, and cystoscopy. Notably, a total of 259 procedures were performed in the treatment of urologic complications, representing 14.4 procedures per patient and 24.6 procedures per patient with ureteral stricture. Logistic regression demonstrated active smoking at the time of diagnosis to be a predictor of procedural complication. CONCLUSION: Radiotherapy in the treatment of cervical cancer is associated with a high rate of urologic procedural complication. These complications often require numerous procedures and long-term management given their complexity. These findings suggest a need for awareness and plans for multidisciplinary management of urologic complications in this patient population.
