RESUMO
OBJECTIVE: To characterize the rates of endovascular stapler complications during hilar ligation in minimally invasive radical nephrectomy over the last 10 years. MATERIAL AND METHODS: We reviewed the Food and Drug Administration Manufacturer and User Facility Device Experience database from January 1, 2009 to August 1, 2019. Staplers were categorized according to type, namely Ethicon Inc. endocutters (Johnson & Johnson, New Brunswick NJ); Endo-GIA (Medtronic, Minneapolis MN); and Endo-TA (Medtronic, Minneapolis MN). RESULTS: There were 383 cases of complications involving staplers, 63% with Ethicon endocutters; 28% with GIA; and 9% with TA. 22 deaths (5.7% of total complications) were attributed to staplers. No deaths or reoperations occurred due to TA staplers. TA staplers were also associated with a reduced incidence of conversion to open as compared to Ethicon and GIA staplers. Apart from one device, manufacturer evaluation of returned devices either showed no abnormalities or attributed fault to improper use of staplers. DISCUSSION: We characterized stapler complications during a 10-year period for minimally invasive radical nephrectomy. No deaths or reoperations occurred due to TA staplers, perhaps due to cutting and stapling occurring in separate steps. Based on manufacturer evaluation attributing stapling malfunctions to human errors, training of operating room staff on proper use of these devices is critical to prevent potentially significant complications from occurring.

Patients with localized urethral melanoma have a high risk of recurrence and poor disease-specific survival. Multi-disciplinary approach including surgery, radiation therapy, and chemotherapy/immunotherapy is needed to maximize survival. Current research efforts include investigation of novel tyrosine kinases as well as the combination of targeted therapies with immunotherapies in this population. Combinations may provide a synergistic effect to overcome various obstacles to disease response.

We present a case of a patient with ataxia, dysmetria, and hemiparesis after a stroke in the corona radiata. The patient had an excellent clinical course with near resolution of symptoms in 2 and a half weeks and returned back to work full duty and full time a couple of weeks later. We use videos of several neurologic tests to demonstrate and characterize the dysmetria. Interestingly, a key characteristic of the dysmetria appears to be different from that seen in patients with dysmetria arising from a cerebellar, thalamic, or pontine lesion. We propose a possible neurophysiologic mechanism-damage to and redundancy of part of the corticopontine portion of the cerebellar circuit located in the corona radiata-respectively responsible for this condition and recovery. We also discuss how a simple noninvasive study of patients with ataxia and dysmetria secondary to corona radiata, thalamic, pontine, and possibly other brain lesions may be helpful in elucidating the contribution of pontocerebellar fibers and other structures to motor control. LEVEL OF EVIDENCE: V.

Each year more than 1.7 million people experience traumatic brain injury. This qualitative descriptive study sought to describe how surrogate decision makers for patients with severe traumatic brain injury made the decision to withdraw or continue life support, and whether they believed that the health care team could have been of greater assistance. Six of 10 surrogates elected to withdraw life-sustaining treatment. Eight surrogates said that they would make the same proxy decisions if they had to do it again. Surrogates used multiple inputs to make treatment decisions and described the need for support from a trauma advanced practice nurse or palliative care team.
