Notes

The Epithelial Mobile Trickle Path.
Ocular torsion was an issue of considerable contention in nineteenth century visual science. The possibility of torsion in opposite directions seemed fanciful and yet this is what Nagel proposed in order to maintain cyclofusion for lines inclined in opposite directions relative to the horizontal. Similar rotations about the vertical resulted in a depth effect with no cyclovergence. The involvement of cyclovergence remained hotly debated until photographic recording of eye movements verified it.
Treatment options for persistent and recurrent Cushing's disease (CD) include an individualized approach for repeat surgery, medical treatment, radiation therapy (RT), and bilateral adrenalectomy (BLA).

In this expert opinion perspective, the authors review the latest treatment(s) for persistent/recurrent CD. A PubMed search was undertaken (English articles through May 2020) and relevant articles discussed. Protein Tyrosine Kinase inhibitor Repeat pituitary surgery should be considered in most patients with proven hypercortisolism; there is potential for cure with low risk of major complications. Medical therapy is valuable either alone, while awaiting the effects of RT, or in preparation for BLA. Medical therapy includes steroidogenesis inhibitors, agents that act at the pituitary or glucocorticoid receptor level, and novel agents in development. Radiation therapy has been used successfully to treat CD, but hypopituitarism risk and delayed efficacy (improved with radiosurgery) are major drawbacks. Laparoscopic BLA is safe and effective in patients with severe, difficult-to-manage hypercortisolism, but long-term follow-up is required as corticotroph tumor progression can develop.

Treatment of persistent/recurrent CD is challenging. Most patients require >1 therapy to achieve long-lasting remission. There is currently no ideal single treatment option that provides high and rapid efficacy, low adverse effects, and preserves normal pituitary-adrenal axis function.

To investigate lumen loss (LL) at 1 year after bare nitinol stent (BNS) implantation for de novo superficial femoral artery (SFA) lesions.

The subjects were 701 consecutive patients (mean age 74±9 years; 492 men) with 817 de novo SFA lesions treated with BNS implantation between January 2004 and September 2015. The mean lesion length was 141±88 mm and the mean vessel diameter was 5.4±0.9 mm. The endpoint was LL at 1 year after BNS implantation. Secondary outcomes were restenosis and target lesion revascularization (TLR) estimated using the Kaplan-Meier method; estimates are reported with the 95% confidence interval (CI). LL was defined as the minimum lumen diameter immediately after BNS implantation minus that at 1 year measured by angiographic quantitative vessel analysis. The distribution of LL in the overall population was estimated using an accelerated failure time model.

Mean LL at 1 year was estimated to be 1.74±1.28 mm (95% CI 1.63 to 1.84). Current smoking was positively associated with LL (p=0.015), whereas lack of cilostazol use was correlated with an increase in LL (p=0.001). Reference vessel diameter and lesion length did not have any significant association with LL at 1 year. The 1-year cumulative estimate of restenosis was 25% (95% CI 22% to 28%); the corresponding value for TLR was 18% (95% CI 15% to 21%).

Mean LL progressed by at least 1.6 mm at 1 year after BNS implantation. The risk factors for increased LL were current smoker and lack of cilostazol use.

To analyze the overall performance of flexible nitinol stents used to line chimney grafts (CGs) during chimney endovascular aneurysm repair (chEVAR) of pararenal pathologies.

A retrospective review was conducted of all 116 elective patients (mean age 74.3±7.2 years; 103 men) who underwent chEVAR with balloon-expandable Advanta V12/iCAST CGs in combination with the Endurant stent-graft between January 2009 and December 2017 at a single center. CG lining with a nitinol stent was electively performed in 43 target vessels of 32 patients. The Kaplan-Meier method was used to estimate the primary outcomes of CG patency and freedom from reintervention (FFR) at the patient level and according to the use of a stent to line the CG. Estimates are reported with the 95% confidence interval (CI). Adjusted odds ratios (ORs) were calculated to identify any confounding effect between the presence/absence of a stent lining or according to the number of CGs.

The mean radiological follow-up was 27.3 months (range 22.1-32.6)el.
To present a new outcomes-based registry to collect data on outpatient endovascular interventions, a relatively new site of service without adequate historical data to assess best clinical practices. Quality data collection with subsequent outcomes analysis, benchmarking, and direct feedback is necessary to achieve optimal care.

The Outpatient Endovascular and Interventional Society (OEIS) established the OEIS National Registry in 2017 to collect data on safety, efficacy, and quality of care for outpatient endovascular interventions. Since then, it has grown to include a peripheral artery disease (PAD) module with plans to expand to include cardiac, venous, dialysis access, and other procedures in future modules. As a Qualified Clinical Data Registry approved by the Centers for Medicare and Medicaid Services, this application also supports new quality measure development under the Quality Payment Program. All physicians operating in an office-based laboratory or ambulatory surgery center can use the Regis interventional procedures (87.6%). The hospital transfer rate was 0.62%, with 88 urgent/emergent transfers and 24 elective transfers. The overall complication rate for the Registry was 1.87% (n=338), and the rate of major adverse events was 0.51% (n=92). Thirty-day mortality was 0.03% (n=6).

This report describes the current structure, methodology, and preliminary results of OEIS National Registry, an outcomes-based registry designed to collect quality performance data with subsequent outcome analysis, benchmarking, and direct feedback to aid clinicians in providing optimal care.
