Palladium-catalyzed cross-coupling reactions are indispensable tools in molecular syntheses with numerous applications in academia and for the practitioners in the chemical and pharmaceutical industries.
Aim: To evaluate the efficacy of a new sclerotization technique with pure ethanol in the treatment of symptomatic renal cysts. Patients and Methods: Fourteen patients having renal cysts with a meant diameter of 10 (range 5–15) cm were treated. Our technique includes: ultrasound-guided percutaneous puncture with an 18-gauge needle, positioning of a 5-Fr catheter, complete cyst fluid aspiration, injection of pure alcohol equal to 15% of the initial cyst volume, and alcohol aspiration after 90 min. The procedure was repeated eight times within 5 days. The patients were followed up by ultrasound and/or CT scan for 1 year. Results: All patients became symptom free. Follow-up showed a progressive reduction of the cyst diameter in all cases. Three cysts only (in 2 patients; cyst diameter <2 cm) persisted after 12 months. No significant complications were observed. Conclusions: In our experience, injections of pure ethanol in renal cysts, repeated after some days, were effective in eliminating recurrences and related symptoms. The procedure was not associated with significant complications. Our findings suggest that it be considered the first-choice procedure in the treatment of renal cysts, due to the good results and the low cost of ethanol.
The objective of this is to compare the surgical outcomes of partial nephrectomy (PN), performed via three different approaches: robot-assisted (RAPN), laparoscopic (LPN), and open (OPN), in a single non-academic regional center. The data of patients undergoing PN at our Department from 2005 to 2016 were prospectively collected. A logistic regression model adjusted for preoperative variables (age, tumor size, creatinine and hemoglobin, ASA and Padua scores) was performed to evaluate whether transfusion, conversion, and postoperative complication rate were influenced by the surgical approach. Overall 270 patients underwent PN: analysis included 253 cases (RAPN = 110, LPN = 70, OPN = 73). Preoperative variables did not differ significantly among the three groups. Shorter operative (130 vs 180 and 200') and ischaemia (12 vs 23 and 22') times and longer hospital stay (8 vs 7 and 6 days) were found in the OPN group as compared to LPN and RAPN, respectively. The RAPN group included a higher rate of pT1b (31.8 vs 14.2 and 15%) and malignant histotype (90 vs 82.9 and 68.5%) as compared to LPN and OPN, respectively. Clavien Grade III-IV complications were lower in the RAPN (7.2%) as compared to OPN (12.3%) and LPN (17.1%) groups. Multivariate analysis showed a lower risk for conversion, transfusion and overall complications in the RAPN group versus LPN and OPN. The surgical approach affects the perioperative outcomes in a regional setting. The advantages of RAPN over OPN (lower risk of conversion, transfusion, and overall complications) are extended over LPN as well, although OPN offered faster operative and ischemia times at the expense of greater blood loss and hospital stay.
The therapeutic efficacy for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is currently unsatisfactory. The aim of the present study was to assess the safety and efficacy of pollen extract in association with vitamins (DEPROX 500®) in males with CP/CPPS. All patients with a diagnosis of CP/CPPS attending the same urologic centre between March and October 2012 were enrolled in this randomised controlled phase III study. Participants were randomised to receive oral capsules of DEPROX 500® (two capsules every 24 h) or ibuprofen (600 mg, one tablet three times a day) for four weeks. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), International Prostate Symptom Score and Quality of Well-Being (QoL) questionnaires were used. In the intention-to-treat analysis, 87 males (25 class IIIa and 62 class IIIb) with a mean age of 33.6±5.9 years were randomly allocated to the DEPROX 500® (n=41) or ibuprofen (n=46) treatment groups. At the follow-up examination (following one month of treatment), in the DEPROX 500® group, 31/41 patients (75.6%) reported an improvement in quality of life, defined as a reduction of the NIH-CPSI total score by ≥25%, compared with 19/46 (41.3%) in the control group (P=0.002). The greater improvement in the DEPROX 500® group compared with the ibuprofen group was statistically significant (treatment difference in the NIH-CPSI pain domain, −2.14±0.51, P<0.001; QoL scores, P=0.002). All patients were negative at the Meares-Stamey test evaluation. Adverse events were less frequent in the DEPROX 500® group than in the ibuprofen group. The DEPROX 500® treatment significantly improved total symptoms, pain and quality of life compared with ibuprofen in patients with CP/CPPS, without severe side-effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
