A locally p-adaptive approach for Large Eddy Simulation of compressible flows in a DG framework

We investigate the possibility of reducing the computational burden of LES models by employing local polynomial degree adaptivity in the framework of a high-order DG method. A novel degree adaptation technique especially featured to be effective for LES applications is proposed and its effectiveness is compared to that of other criteria already employed in the literature. The resulting locally adaptive approach allows to achieve significant reductions in computational cost of representative LES computations

Multimodal therapy for category III chronic prostatitis/chronic pelvic pain syndrome in UPOINTS phenotyped patients

The complex network of etiological factors, signals and tissue responses involved in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) cannot be successfully targeted by a single therapeutic agent. Multimodal approaches to the therapy of CP/CPPS have been and are currently being tested, as in the frame of complex diagnostic-therapeutic phenotypic approaches such as the urinary, psychosocial, organ-specific, infection, neurological and muscle tenderness (UPOINTS) system. In this study, the effect of combination therapy on 914 patients diagnosed, phenotyped and treated in a single specialized prostatitis clinic was analyzed. Patients received \u3b1-blockers, Serenoa repens (S. repens) extracts combined or not with supplements (lycopene and selenium) and, in the presence of documented or highly suspected infection, antibacterial agents. Combination treatment induced marked and significant improvements of National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) prostatitis symptom scores, International Index of Erectile Function (IIEF) sexual dysfunction scores, urinary peak flow rates and bladder voiding efficiency. These improvements, assessed after a 6-month course of therapy, were sustained throughout a follow-up period of 18 months. A clinically appreciable reduction of 656 points of the total NIH-CPSI score was achieved in 77.5% of patients subjected to combination therapy for a period of 6 months. When the patients were divided in two cohorts, depending on the diagnosis of CP/CPPS [inflammatory (IIIa) vs. non-inflammatory (IIIb) subtypes], significant improvements of all signs and symptoms of the syndrome were observed in both cohorts at the end of therapy. Intergroup comparison showed that patients affected by the IIIa sub-category of CP/CPPS showed more severe signs and symptoms (NIH-CPSI total, pain and quality of life impact scores, and Qmax) at baseline when compared with IIIb patients. However, the improvement of symptoms after therapy was significantly more pronounced in IIIa patients when compared with IIIb patients. In contrast to current opinion, the evidence emerging from the present investigation suggests that the inflammatory and non-inflammatory sub-categories of CP/CPPS may represent two distinct pathological conditions or, alternatively, two different stages of the same condition. In conclusion, a simple protocol based on \u3b1-blockers, S. repens extracts and supplements and antibacterial agents, targeting the urinary, organ specific and infection domains of UPOINTS, may induce a clinically appreciable improvement of the signs and symptoms of CP/CPPS in a considerable percentage of patients. In patients not responding sufficiently to such therapy, second-line agents (antidepressants, anxiolytics, muscle relaxants, 5-phosphodiesterase inhibitors and others) may be administered in order to achieve a satisfactory therapeutic response

Group B streptococcal meningitis in an adult: A possible complication of olecranon bursitis

Background: We report a man with septic olecranon bursitis who had an early development of meningitis. Case Summary: A 74-year-old man presented to the emergency room with malaise, headache, mental confusion, a fever unsuccessfully treated with oral NSAIDs and ice, and with a 10-day history of pain and swelling in his right elbow. Clinical and laboratory evaluation excluded other causes and microbiological evaluation documented a S. agalactiae infection. Antibiotic treatment induced a rapid improvement, without the development of side effects. Conclusion: This is the first report on olecranon bursitis and concomitant meningitis related to S. agalactiae infection

Shigella flexneri-induced vaginitis in a prepubertal children: description of a case

In prepuberal girls vulvo-vaginitis are caused by germs of intestinal origin,mycetes, Gardnerella vaginalis, protozoa. Shigella is an uncommon agent able to induce valvovaginitis in children. We report the case of a 7-year-old girl with chronic vulvo-vaginitis caused by S. flexneri. Antibiotic Susceptibility Testing revealed that S. flexnery was sensible to cefotaxime, amoxicillin, imipenem, ciprofloxacin, but resistant to amikacin, cefazolin, gentamycin, ampicillin and tetracycline. A treatment with ciprofloxacin brought to a rapid resolution of all symptoms. At the follows up at 3 and 6 months the patient did not report symptoms of infection or articular cartilage abnormality; microbiological evaluations were also negative. Even if it is a single case report and other clinical trial may be performed in order to validate this hypothesis,we speculate that in patient with vulvo-vaginal infection living in environment with low hygiene care, a carefully microbiological evaluation of uncommon agents may be performed

Organizational impact of the introduction of a new portable syringe pump for iloprost therapy in Italian hospital settings

Purpose: The study aims at assessing the organizational and economic impact related to the use of a new portable syringe pump (Pompa Infonde®, Italfarmaco S.p.A., Cinisello Balsamo, Italy) at a hospital level. Methodology: Based on the HTA approach, the analysis assessed the organizational and economic impact of the new device at hospital level, using the traditional methods of Iloprost infusion as comparator. After a pilot evaluation, the organizational impact was assessed within 24 Italian hospitals. Structured interviews were conducted with clinicians and nurses. According to the Hospital-Based HTA approach, a questionnaire assessed the impact on human resources, training activities, internal meetings, spaces needed, facilities, clinical practice implications. Using Activity Based Costing approach, the economic evaluation was performed within the pilot center “Ospedale Civile” of Legnano, Italy. Findings: The new device leads to a positive managerial impact, with a substantial reduction of time to monitor patients by nurses. This resulted in a better management of human resources and in a reduction in nursing cost. Although a mild negative impact on training time for personnel, the structured interviews allowed the identification of three main areas of positive impact: (i) efficiency of internal processes, (ii) clinical pathways, (iii) synergies between wards. Originality: The organizational impact of Pompa Infonde®, showed that it is an efficient alternative to traditional methods, with benefits in the management of patients administered with Iloprost
