Background: Small renal masses are increasingly being discoveredincidentally on imaging performed for another reason. Thestandard of care for these masses involves excision by open orlaparoscopic techniques. Recently, ablative techniques such asradiofrequency ablation (RFA) and cryoablation have taken a moreprominent role in the treatment algorithm for these masses. Wesought to evaluate the efficacy and safety of radiofrequency ablationin the treatment of renal tumours.Methods: We conducted a review of the literature. There was nolanguage restriction. We obtained studies from the followingsources: the Cochrane Library, PubMed, EMBASE, LILACS andCurrent Controlled Trials.Results: We identified no clinical trials in the literature. Thus wedescribed the results from case series and retrospective studieswith a reasonable sample size (number of reported patients in eachstudy > 65). Most patients undergoing RFA had T1a disease witha mean tumour size of about 3 cm. Radiofrequency ablation wasusually performed percutaneously with image guidance. Reportedfollow-up was short and ranged from 1 to 30 months. Most seriesused radiographic response as a surrogate for cancer control. Therates of local recurrence of the tumour were as high as 13.0%(average 8.5%) and were slightly higher than those associated withcryoablation and partial nephrectomy. Complications includedhemorrhage, ureteral strictures and loss of a renal unit.Conclusion: Our review demonstrates that RFA is a suitable andpromising therapy in patients with small renal tumours who areconsidered to be poor candidates for more involved surgery.However, clinical trials with long-term data are needed to establishthe oncological efficacy.Contexte : De petites masses rénales sont de plus en plus souventdécouvertes de façon fortuite lors d’épreuves d’imagerie commandéespour une autre raison. Les soins standard pour ces massesincluent une excision par chirurgie ouverte ou par laparoscopie.Dernièrement, des techniques comme l’ablation par radiofréquence(ARF) et la cryoablation ont pris plus d’importance dans l’algorithmede traitement. Nous examinons l’efficacité et l’innocuité del’ablation par radiofréquence dans le traitement des tumeurs rénales.Méthodologie : Une revue de la littérature a été effectuée, sansrestriction de langue. Des articles ont été obtenus des sources suivantes: la Bibliothèque Cochrane, PUBMED, EMBASE, LILACS etCurrent Controlled Trials.Résultats : Comme aucun essai clinique n’a pu être cerné dans cesbases de données, nous décrivons les résultats d’études de cas etd’analyses rétrospectives avec populations de taille raisonnable(nombre de patients pour chaque étude > 65). La vaste majoritédes patients ayant subi une ARF présentaient une tumeur T1a detaille moyenne d’environ 3 cm. L’ARF était habituellement effectuéepar voie percutanée et guidée par imagerie. Le suivi était court,allant de 1 à 30 mois. La plupart des études sérielles avaient recoursà la réponse radiographique comme paramètre de substitutionde la maîtrise du cancer. Les taux de récidive locale de la tumeuratteignaient 13.0 % (moyenne 8.5%), et étaient en général légèrementplus élevés que les taux notés avec la cryoablation et lanéphrectomie partielle. Les complications signalées étaient les suivantes: hémorragie, sténose urétérale et perte d’une unité rénale.Conclusion : Le présent article montre que l’ARF est une techniqueconvenable et prometteuse chez les patients porteurs depetites tumeurs rénales considérés comme de mauvais candidatspour une intervention plus lourde. Cependant, il est impératifd’effectuer des essais cliniques à long terme afin d’établir dans unavenir rapproché l’efficacité oncologique de cette technique.

Purpose: Small renal masses are increasingly being discovered incidentally on imaging for another reason. The standard of care of these masses involves excision by open or laparoscopic techniques. Recently, ablative techniques, such as radiofrequency ablation (RFA) and cryoablation, have taken a more prominent role in the treatment algorithm of these masses. We evaluate the effectiveness and safety of cryoablation to treat renal tumours.Methods: A review of the literature was conducted. There was no language restriction. Studies were obtained from the following sources: the Cochrane Library, PUBMED, EMBASE and LILACS.Results: There was no clinical trial identified in the literature. Thus, we described the results from 23 case series and retrospective studies with a reasonable sample size (number of reported patients in each study ≥30), with a total of 2104 analyzed tumours from 2038 patients. There was wide variability in the outcomes reported, but success rates were generally good. Follow-up was generally short, but some series reported outcomes at 5 years. The most common complications reported were hemorrhage (some of the patients requiring transfusion), perinephric hematoma and urine leaks.Conclusion: Cryoablation presents a feasible treatment for patients with small renal masses. Only short-term data are available and, assuch, meaningful conclusions regarding long-term cancer control cannot be made. More rigorous studies are needed.

Two decades of research into problematic Internet use have not yielded an established definition, much less an accepted treatment algorithm that is based on the psychopharmacological and psychotherapeutic interventions that have been tested. Meanwhile, technology-mediated tools that purport to curb unnecessary use of Internet-related technologies and the associated negative consequences are gaining in popularity, despite the lack of rigorous clinical trials into their efficacy and safety. Some popular new offerings that vary in browser, operating system and platform compatibility are reviewed. While they share similar goals as “traditional” treatments, they may be more efficient, scalable, and affordable. Using technology against itself may be counter-intuitive, but the popularity of these tools and their potential advantages make them worthy of researchers’ attention. Telepsychiatry platforms, which are gaining a foothold in the treatment of established disorders, may, paradoxically, also prove beneficial for the management of problematic use of Internet-related technologies.

Background: Partial nephrectomy (PN) is now the gold standardfor the surgical treatment of small renal masses. We evaluated theeffect of WIT and other factors on RDF assessed by preoperativeand postoperative renal scintigraphy.Methods: Between 2003 and 2008, 182 consecutive laparoscopicPN (LPN) were performed in an academic centre. Among those,56 had mercaptoacetyl triglycine (MAG3) lasix renal scintigraphypreoperatively and postoperatively.Results: Medians for age, preoperative estimated glomerular filtrationrate and computed tomography scan tumour size were 62years, 82 mL/min/1.73m2 and 26 mm, respectively. Median WITand preoperative RDF were 30 minutes and 50%, respectively.Median loss of RDF after surgery was 14%. Linear regression curvesshowed that loss in RDF rate was 0.2% per minute when WIT was<30 minutes and 0.7% per minute when WIT was ≥30 minutes.In multivariate analysis, length of WIT and endophytic tumourlocation were associated with a statistically significant loss of RDF(p < 0.05), but only in the group who experienced >30 minutesof WIT.Interpretation: Our results suggest that the factors associated withloss of RDF are not the same before and after 30 minutes of WITand that the rate of loss in RDF increases after 30 minutes. Since,the effect of WIT is small up to 30 minutes, we believe that surgeryshould focus on limiting the resection of normal parenchymaand to ensure negative margins and hemostasis, rather than onpremature unclamping.

Objective: The objective of this review is to describe the outcomes of patients treated with ceftaroline in the non-Food and Drug Administration (FDA) approved indication of methicillin-resistant Staphylococcus aureus (MRSA) infections in both pediatric and adult populations. Data sources: A systematic overview was conducted by searching PubMed, Medline, and The Cochrane Library up to January 2019. Study selection and data extraction: All English-language clinical trials and case reports related to the efficacy of ceftaroline in new, not-yet-approved FDA indications in MRSA infections in pediatric or adult populations. Data synthesis: In the case of MRSA bacteremia (MRSAB) infections, three different randomized studies in pediatric patients showed effectiveness of ceftaroline. When used in the case of adult populations with MRSA bacteremia, a small trial of 16 patients showed 50% clinical success in patients with acute bacterial skin and skin structure infections versus 63% clinical success in patients with community-acquired bacterial pneumonia. Another case series of six refractory case reports showed 50% clinical success of ceftaroline in patients with MRSA. Conclusions: Although there are few case reports and limited data to date, ceftaroline fosamil should continue to be studied as an alternative therapy in MRSA infections in both pediatric and adult populations. Clinical success rates of ceftaroline were, in most cases, considered high when treating patients with MRSA infection. More clinical trials need to be studied. In the specific case of MRSA bacteremia, the treatment options remain few and ceftaroline should be extensively studied for the salvage treatment of MRSAB.
