OBJECTIVE To investigate the feasibility and clinical outcome of extracorporeal shock‐wave therapy (ESWT) for patients suffering from chronic pelvic pain syndrome (CPPS). PATIENTS AND METHODS The study included 34 patients who had had CPPS for ≥3 months, who were investigated in two subsequent studies. ESWT was administered using a perineal approach with two different standard ESWT devices with and without an ultrasonographic positioning system. The follow‐up was at 1, 4 and 12 weeks after ESWT, to evaluate the effects on pain, quality of life and voiding. Imaging studies and changes in prostate‐specific antigen (PSA) were used to investigate the safety and side‐effects of ESWT. RESULTS All patients completed the treatments and follow‐up; there were statistically significant improvements in pain and quality of life after ESWT. Voiding conditions were temporarily improved but with no statistical significance. Perineal ESWT was easy and safe to administer with no anaesthesia on an outpatient basis. Side‐effects could be excluded clinically, by imaging studies and by changes in PSA level. CONCLUSION Perineal ESWT must be considered as a promising new therapy for CPPS, in particular as it is easy to apply and causes no side‐effects.

PurposeWe report an outbreak of urinary tract infections (UTIs) caused by Myroides odoratimimus, which occurred in the largest clinical hospital in western Romania.Patients and methodsFrom June to August 2017, four strains of M. odoratimimus were isolated from the urine samples of patients hospitalized in the urology, diabetes, and surgery departments. Hospital records of all patients whose urine cultures were positive for M. odoratimimus were reviewed retrospectively. We also reviewed the cases reported in the literature.ResultsAll UTIs, except one, were hospital-acquired infections. All patients with M. odoratimimus UTIs were immunocompromised. Three patients underwent urinary catheterization with a Foley’s catheter upon admission in the emergency department and one presented for replacement of ureterostomy tubes. All Myroides isolates were resistant to almost all the tested antibiotics. Two patients were successfully treated with tigecycline and one was receiving antimicrobial treatment for another infection at the time of isolation of the microorganism.ConclusionAlthough M. odoratimimus is an uncommon pathogen, clinicians should be aware of its ability to cause UTI outbreaks, especially in the immunocompromised population. Due to its multi-drug resistance, it is important to rapidly identify Myroides spp. in order to choose the best treatment regimen.

The present study proposes a classification of renal cancer tumor blood vessels according to their morphology and maturation grade. We identified four vascular patterns: reticular, diffuse, fasciculated and trabecular. The reticular pattern was present in 63% of cases, being characterized by the predominance of mature CD34+/SMAct+ tumor vessels, highly interconnected. For this pattern, 74% of cases had vascular invasion, and a significant correlation was observed between tumor grade and immature state of tumor vessels (p = 0.022). The diffuse pattern was observed in 23% of cases and was characterized by non-interconnected vessels predominantly of mature CD34+/SMAct+ type and vascular invasion in 64% of cases. Only 8% of cases, had a fasciculate model of vessels distribution, all of them being of mature type, located in the connective axis of papillary renal tumors. For this pattern vascular invasion was found in 50% of cases. In 6% of cases a trabecular pattern was observed and the lowest rate of vascular invasion was registered. We defined here four distinct vascular patterns in renal cell carcinomas showing a strong impact on vascular invasion. A complete morphological and molecular characterization of tumor vessels would be beneficial in elucidating the mechanisms that underlie the ineffectiveness of antiangiogenic/antitumor therapies.

IntroductionWithin the last years, there has been a trend in many hospitals to switch their surgical activity from open/laparoscopic procedures to robotic surgery. Some open surgeons have been shifting their activity to robotic surgery. It is still unclear whether there is a transfer of open surgical skills to robotic ones.AimTo evaluate whether such transfer of skills occurs and to identify which specific skills are more significantly transferred from the operative table to the console.Material and methodsTwenty-five volunteers were included in the study, divided into 2 groups: group A (15 participants) – medical students (without any surgical experience in open, laparoscopic or robotic surgery); and group B (10 participants) – surgeons with exclusively open surgical experience, without any previous laparoscopic or robotic experience. Participants were asked to complete 3 robotic simulator console exercises structured from the easiest one (Peg Board) to the toughest one (Sponge Suture). Overall scores for each exercise as well as specific metrics were compared between the two groups.ResultsThere were no significant differences between overall scores of the two groups for the easiest task. Overall scores were better for group B as the exercises got more complex. For the intermediate and high-difficulty level exercises, most of the specific metrics were better for group B, with the exception of the working master space item.ConclusionsOur results suggest that the open surgical skills transfer to robotic skills, at least for the very beginning of the training process.

Background and Objectives: Over decades, prostate cancer (PCa) has become one of the leading causes of cancer mortality in men. Extensive evidence exists that microRNAs (miRNAs or miRs) are key players in PCa and a new class of non-invasive cancer biomarkers. Materials and Methods: We performed miRNA profiling in plasma and tissues of PCa patients and attempted the validation of candidate individual miRs as biomarkers. Results: The comparison of tissue and plasma profiling results revealed five commonly dysregulated miRs, namely, miR-130a-3p, miR-145-5p, miR-148a-3p, miR-150-5p, and miR-365a-3p, of which only three show concordant changes—miR-130a-3p and miR-150-5p were downregulated and miR-148a-3p was upregulated in both tissue and plasma samples, respectively. MiR-150-5p was validated as significantly downregulated in both plasma and tissue cancer samples, with a fold change of −2.697 (p < 0.001), and −1.693 (p = 0.035), respectively. ROC analysis showed an area under the curve (AUC) of 0.817 (95% CI: 0.680–0.995) for plasma samples and 0.809 (95% CI: 0.616–1.001) for tissue samples. Conclusions: We provide data indicating that miR-150-5p plasma variations in PCa patients are associated with concordant changes in prostate cancer tissues; however, given the heterogeneous nature of previous findings of miR-150-5p expression in PCa cells, additional future studies of a larger sample size are warranted in order to confirm the biomarker potential and role of miRNA-150-5p in PCa biology.
