Renal cell carcinoma: The role of radical surgery on different patterns of local or distant recurrence

IntroductionWith the increasing reliance on targeted therapies and immunotherapy, no standard management strategy is today available for the treatment of locally, distant, or both renal cell carcinoma (RCC) recurrences, and their surgical treatment seems to play a crucial role. We report the 20-year experience of our center evaluating the short- and long-term outcomes of patients undergone surgical resection of RCC recurrences, and the possible role of repeated surgical resections of RCC recurrences.Materials and methodsFrom January 1999 to January 2019, 40 patients underwent surgical resection of isolated locally recurrent RCC (iLR-RCC-group), locally recurrent RCC associated with the presence of distant recurrence (LR-DR-RCC-group), and distant-only recurrent RCC (DR-RCC-group). Data regarding pre-, intra-, post-operative course, and follow-up, prospectively collected in an institutional database, were retrospectively analyzed and compared.ResultsiLR-RCC-group was composed of 9 patients, LR-DR-RCC-group of 6 patients, and DR-RCC-group of 25 patients. The recurrence rate was 55.6% (5/9 patients) in iLR-RCC-group, 50% (3/6 patients) in LR-DR-RCC-group, and 44% (11/25) patients in DR-RCC-group, p = 0.830. 3/5 (60%) patients in iLR-RCC-group, 2/3 (66.7%) patients in LR-DR-RCC-group, and 7/11 (63.6%) patients in DR-RCC group underwent to almost one further local treatments of their recurrences, respectively (p = 0.981). No differences in the mean disease-free survival (p = 0.384), overall survival (OS) (p = 0.881), and cancer-specific survival (p = 0.265) were reported between the three groups. In DR-RCC-group, patients who underwent further local treatments of new recurrences presented a longer OS: 150.7 versus 66.5 months (p = 0.004).ConclusionsA surgical resection of RCC recurrences should be always taken in consideration, also in metastatic patients and/or in those who have already undergone surgery of previous RCC recurrence, whenever radicality is still possible, because this approach may offer a potentially long survival.     

Fear,mistrust, and vaccine hesitancy: Narratives of the dengue vaccine controversy in the Philippines

This article applies a qualitative approach to the 2017 dengue vaccine controversy involving Sanofi Pasteur’s Dengvaxia to understand vaccine hesitancy and related anxieties in contemporary Philippines. Through a multisited project that investigated the health aspirations and lived experiences of low- and middle-income Filipinos across urban and rural Philippines, this article distills the perspectives of both ordinary community members and health workers in local and national capacities regarding the controversy—and how it altered their perceptions toward vaccines, health care, and government. Our study reveals widespread mistrust and fear in the communities toward both the state and health institutions following the controversy, with frontline health workers bearing the brunt of the communities’ apprehensions, and the media partly responsible in fomenting these fears. Given the repetitive nature of health and vaccine controversies, this article suggests the importance of responsible journalism, well-calibrated crisis communications, and a people-centered health paradigm that involves exploring local contexts of vaccine hesitancy and mining people’s lived experiences in tackling present and future health crises—especially now in the advent of COVID-19 vaccinations.     

眼睑分裂痣的手术整形研究

目的：探究眼睑分裂痣的不同手术方法和治疗效果。方法随机选取该院在2014年1月—2015年12月收治的60例需要进行眼睑分裂痣手术治疗的患者作为观察对象,将其按照抽签法随机分为A组(n=20)、B组(n=20)和C组(n=20),A组患者采用全厚皮片移植术；B组患者采用转移或推进皮瓣术；C组患者采用皮片移植+皮瓣转移术。首先对3组患者的治疗效果进行观察,然后比较3组患者在治疗后的不良反应发生情况,对比不良反应的发生率。结果3组患者的治疗效果均较好,所有患者的上伤口在1期即全部愈合,未出现明显的睑缘切痕；A组患者中,出现不良反应的患者有1例,占5.0%。B组中,无患者出现不良反应,不良反应发生率为0.0%。C组中,出现不良反应的患者有1例,占5.0%。3组患者之间差异无统计学意义(P﹥0.05)。结论治疗眼睑分裂痣的方法较多,全厚皮片移植术、转移或推进皮瓣术以及皮片移植+皮瓣转移术均有较好的效果,患者无明显的不良反应,并且痊愈的效果较好,手术的操作也较为简便易行,具有较高的安全性和可行性,值得临床推广。     

Symptoms During or Shortly After Isolated Carpal Tunnel Release and Problems Within 24?hours After Surgery

This study used the National Survey of Ambulatory Surgery (NSAS) database to measure the incidence of and risk factors for symptoms in the ambulatory surgery center and problems within 24 h after isolated carpal tunnel release (CTR). The NSAS contained records on 400,000 adult patients with carpal tunnel syndrome who were treated with CTR in 2006, based on ICD-9 codes. The type of anesthesia used and factors associated with symptoms and problems were sought in bivariate and multivariable statistical analyses. The mean duration of the procedure was 16 ± 8.8 min. Only 5 % were performed under local anesthesia without sedation, 45 % with IV sedation, 28 % regional anesthesia, and 19 % general anesthesia. Symptoms in the ambulatory surgery center or a problem within 24 h after discharge were recorded in 10 % of patients, all of them minor and transient, including difficulties with pain and its treatment. The strongest risk factors were male sex, age of 45 years and older, and participation of an anesthesiologist. Local anesthesia and regional anesthesia were associated with more perioperative symptoms and postoperative problems. Most CTR are performed with some sedation in the United States. CTR is a safe procedure: one in 10 patients will experience a minor issue in the perioperative or immediate postoperative period.     

EEG power spectral density under Propofol and its association with burst suppression,a marker of cerebral fragility

ObjectiveUnder General Anesthesia (GA), age and Burst Suppression (BS) are associated with cognitive postoperative complications, yet how these parameters are related to per-operative EEG and hypnotic doses is unclear. In this prospective study, we address this question comparing age and BS occurrences with a new score (BP_TIVA) based on Propofol doses, EEG and alpha-band power spectral densities, evaluated for SEF₉₅ = 8–13 Hz.Methods59 patients (55 [34–67] yr, 67% female) undergoing neuroradiology or orthopedic surgery were included. Total IntraVenous Anesthesia was used for Propofol and analgesics infusion. Cerebral activity was monitored from a frontal electrodes montage EEG.ResultsBP_TIVA was inversely correlated with age (Pearson r = −0.78, p < 0.001), and was significantly lower (p < 0.001) when BS occurred during the GA first minutes (induction). Additionally, the age-free BP_TIVA score was better associated with BS at induction than age (AUC = 0.94 versus 0.82, p < 0.05).ConclusionWe designed BP_TIVA score based on hypnotics and EEG. It was correlated with age yet was better associated to BS occurring during GA induction, the latter being a cerebral fragility sign.SignificanceThis advocate for an approach based on evaluating the cerebral physiological age (« brain age ») to predict postoperative cognitive evolution.     

Anesthetic management of parturients with Arnold Chiari malformation-I: a multicenter retrospective study

BackgroundConsensus regarding the safest mode of delivery and anesthetic management for parturients with Arnold Chiari malformation-I (ACM-I) remains controversial. This study assessed their anesthetic management and reported anesthetic complications during hospitalization for delivery.MethodsThis was a multicenter, retrospective, cohort study of patients with ACM-I undergoing vaginal or cesarean delivery. Data were obtained from the electronic databases of four United States academic institutions using International Classification of Diseases (ICD) codes from 2007–2017 at three sites and 2004–2017 at one site. The primary outcome was anesthetic complications.ResultsData were analyzed for 185 deliveries in 148 patients. Diagnosis of ACM-I was made prior to delivery in 147 (80%) cases. Pre-delivery neurosurgical consultation for management of ACM-I was performed in 53 (36%) patients. Pre-existing symptoms were recorded for 89 (48%) of the deliveries. Vaginal deliveries occurred in 80 (43%) cases, and 62 women (78%) received neuraxial labor analgesia. Cesarean delivery was performed in 105 (57%) cases, of which 70 women (67%) had neuraxial anesthesia and 34 (32%) received general anesthesia. Post-dural puncture headache was reported in three (2%) patients who had neuraxial anesthesia, and in two (12%) patients with syringomyelia. There was one (3%) reported case of aspiration pneumonia with general anesthesia.ConclusionsThe findings suggest that anesthetic complications occur infrequently in patients with ACM-I regardless of the anesthetic management. Although institutional preference in anesthetic and obstetric care appears to drive patient management, the findings suggest that an individualized approach has favorable outcomes in this population.
