Patients exposed to a surgical safety checklist experience better postoperative outcomes, but this could simply reflect wider quality of care in hospitals where checklist use is routine.

Purpose: To present and evaluate the findings of contrast-enhanced ultrasonography (CEUS) in typical cases of acute painful scrotum. Materials and Methods: Nineteen patients aged from 19 to 61 years old were included in the study. All patients underwent grey-scale and color Doppler ultrasonography (US) of the scrotum, followed by imaging after i.v. administration of 2.4 mL of a second generation ultrasound contrast agent (microbubbles of sulphur hexafluoride). Α dedicated, contrast-sensitive technique was used (Contrast Tissue Imaging -CnTI). The diagnosis was confirmed surgically in 6 cases while in the remaining 8 cases it was based on the combination of clinical, imaging and laboratory findings. Results: The final diagnosis was testicular torsion (n = 4), epididymitis (n = 2, one of the cases complicated by abscess), testicular abscess (n = 1), scrotal abscess (n = 1), testicular trauma of varying severity (n = 6). Five out of 19 cases were true negatives: neither clinical examination nor laboratory tests revealed any pathology. CEUS showed complete lack of enhancement in all cases of torsion, permitting a rapid and definitive diagnosis. In the cases of infection complicated by abscesses, CEUS delineated the lesions much better than the combination of B-mode/Color Doppler US. The severely traumatized testicles showed minimal, inhomogeneous or patchy enhancement, while cases of minor trauma showed no significant enhancement defects. Hematomas were presented as non-enhancing lesions. Conclusion: Generally, there was no advantage over Doppler US as has been previously shown. However, CEUS can be used supplementary to traditional Doppler US in the investigation of blunt testicular trauma especially when there is uncertainty in diagnosis after appropriate clinical and radiographic evaluations occurs. Further studies are required to clearly define the indications of this method.

The modern clinical research on prostatitis started with the work of Stamey and coworkers who developed the basic principles we are still using. They established the segmented culture technique for localizing the infections in the males to the urethra, the bladder, or the prostate and to differentiate the main categories of prostatitis. Such categories with slight modifications are still used according to the NIH classification: acute bacterial prostatitis, chronic bacterial prostatitis, Chronic Pelvic Pain Syndrome (CPPS) and asymptomatic prostatitis. Prostatic inflammation is considered an important factor in influencing both prostatic growth and progression of symptoms of benign prostatic hyperplasia and prostatitis. Chronic inflammation/neuroinflammation is a result of a deregulated acute phase response of the innate immune system affecting surrounding neural tissue at molecular, structural and functional levels. Clinical observations suggest that chronic inflammation correlates with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and benign prostatic hyperplasia (BPH) and an history of clinical chronic prostatitis significantly increases the odds for prostate cancer. The NIHNIDDK classification based on the use of the microbiological 4- glasses localization test or simplified 2-glasses test, is currently accepted worldwide. The UPOINT system identifies groups of clinicians with homogeneous clinical presentation and is used to recognize phenotypes to be submitted to specific treatments. The UPOINTS algorithm implemented the original UPOINT adding to the urinary domains (U), psycho-social (P), organspecific (O), infection (I), neurological (N), muscle tension and tenderness (T) a further domain related to sexuality (S). In fact sexual dysfunction (erectile, ejaculatory, libido loss) has been described in 46-92% of cases with a high impact on the quality of life of patients with CP/CPPS. Prostatic ultrasound represents the most popular imaging test in the work-up of either acute and chronic prostatitis although no specific hypo-hyperechoic pattern has been clearly associated with chronic bacterial prostatitis and CPPS. Use of a digital-processing software to calculate the extension of prostatic calcification area at ultrasound demonstrated a higher percentage of prostatic calcification in patients with chronic bacterial prostatitis. Multiparametric Magnetic Resonance Imaging (mpMRI) is the current state-of-the art imaging modality in the assessment of patients with prostate cancer although a variety of benign conditions, including inflammation, may mimic prostate cancer and act as confounding factors in the discrimination between neoplastic and non-neoplastic lesions. Bacteria can infect prostate gland by: ascending the urethra, reflux of urine into the prostatic ducts, direct inoculation of bacteria through inserted biopsy needles or hematogenous seeding. Enterobacteriaceae are the predominant pathogens in acute and chronic bacterial prostatitis, but an increasing role of Enterococci has been reported. Many strains of these uropathogens exhibit the ability to form biofilm and multidrug- resistance. Sexually Transmitted Infections (STI) agents, in particular Chlamydia trachomatis and Mycoplasma genitalium, have been also considered as causative pathogens of chronic bacterial prostatitis. On the contrary the effective role in genital diseases of other "genital mycoplasmas" is still a much debated issue. Sexually Transmitted Infections agents should be investigated by molecular methods in both patient and sexual partner. “Next generation” investigations, such as cytokine analysis, cytological typing of immune cells could help stratifying the immune response. Epigenetic dysregulation of inflammatory factors should be investigated according to systemic and compartment-specific signals. The search for biomarkers should also include evaluation of hormonal pathways, as measurement of estrogen levels in semen. Antimicrobials are the first line agents for the treatment of bacterial prostatitis. The success of antimicrobial treatment depends on the antibacterial activity and the pharmacokinetic characteristics of the drug which must reach high concentrations in prostate secretion and prostate tissue. Acute bacterial prostatitis can be a serious infection with a potential risk for urosepsis For iInitial treatment of severely ill patients, intravenous administration of high doses of bactericidal antimicrobials, such as broad-spectrum penicillins, third-generation cephalosporins or fluoroquinolones, is recommended in combination with an aminoglycoside. Use of piperacillin-tazobactam and meropenem is justified in presence of multiresistant gramnegative pathogens. The antibiotic treatment of chronic prostatitis is currently based on the use of fluoroquinolones that, given for 2 to 4 weeks, cured about 70% of men with chronic bacterial prostatitis. For the treatment of Chlamydial prostatitis macrolides were shown to be more effective than fluoroquinolones, whereas no differences were observed in microbiological and clinical efficacy between macrolides and tetracyclines for the treatment of infections caused by intracellular pathogens. Aminoglycosides and fosfomycin could be considered as a therapeutic alternative for the treatment of quinolone resistant prostatitis. Use of alpha-blockers in CP/CPPS patients with urinary symptoms and analgesics +/- non steroidal anti-inflammatory drugs (NSAID), in presence of pain demonstrated a reduction of symptoms reduction and an improvement of quality of life, although long term use of NSAID is limited by side effect profile. However, the multimodal therapeutic regimen by contemporary use of alphablockers, antibiotics and anti-inflammatory showed a better control of prostatitis symptoms than single drug treatment. Novel therapeutic substances for the treatment of pain, such as the cannabinoid anandamide would be highly interesting to test. An alternative for the treatment of chronic prostatitis/chronic pelvic pain syndrome is phytotherapy, as primary therapy or in association with other drugs. Quercetin, pollen extract, extract of Serenoa repens and other mixtures of herbal extracts showed a positive effect on symptoms and quality of life without side effects. The association of CP/CPPS with alterations of intestinal function has been described. Diet has its effects on inflammation by regulation of the composition of intestinal flora and direct action on the intestinal cells (sterile inflammation). Intestinal bacteria (microbiota) interacts with food influencing the metabolic, immune and inflammatory response of the organism. The intestinal microbiota has protective function against pathogenic bacteria, metabolic function by synthesis of vitamins, decomposition of bile acids and production of trophic factors (butyrate), and modulation of the intestinal immune system. The alteration of the microbiota is called “dysbiosis” causing invasive intestinal diseases pathologies (leaky gut syndrome and food intolerances, irritable bowel syndrome or chronic inflammatory bowel diseases) and correlating with numerous systemic diseases including acute and chronic prostatitis. Administration of live probiotics bacteria can be used to regulate the balance if intestinal flora. Sessions of hydrocolontherapy can represent an integration to this therapeutic approach. Finally, microbiological examination of sexual partners can offer supplementary information for treatment.

During the last years, pharmaceutical innovations in primary care are dramatically less frequent and will be even more rare in the next future. In this context, preclinical and clinical research oriented their interest toward natural compounds efficacy and safety, supporting the development of a new “nutraceutical” science. Medicinal plants, in the form of plant parts or extracts of them, are commonly used for the treatment of prostate diseases such as benign hypertrophy, prostatitis and chronic pelvic pain syndrome. The pharmacological properties searched for the treatment of prostatic diseases are anti-androgenic, anti-estrogenic, antiproliferative, antioxidant and anti-inflammatory. The most studied and used medicinal plants are Serenoa repens, Pygeum africanum and Urtica dioica. Other promising plants are Cucurbita pepo, Epilobium spp, Lycopersum esculentum, Secale cereale, Roystonea regia, Vaccinium macrocarpon. In parallel, epidemiological studies demonstrated that diet may play an important role on incidence and development of prostatic diseases. The Mediterranean diet is rich of elements with anti-oxidant properties that act as a protective factor for prostatic cancer. Similarly, low intake of animal protein, high intake of fruits and vegetable, lycopene and zinc are a protective factor for benign prostatic hyperplasia (BPH). Serenoa repens in the treatment of symptoms of BPH has been tested either alone or, more frequently, in combination with other medicinal plants, alpha-blockers and inhibitors of 5- alpha reductase (5-ARI). Recent meta-analyses found the effectiveness of Serenoa repens similar or inferior of that of finasteride and tamsulosin but clearly higher than that of placebo in the treatment of mild and moderate low urinary tract symptoms (LUTS), nocturia and discomfort. Clinical trials showed potential synergistic effect of Serenoa repens with other medicinal plants and drugs. In addition to Serenoa repens, there are many other medicinal plants for which clinical evidence is still controversial. Urtica dioica, Pygeum africanum and Curcubita pepo can be considered as an adjunct to the common therapies and their use is supported by studies showing improvement of symptoms and flowmetric indices. Lycopene and selenium are natural products with antioxidant and anti-inflammatory action. The combination of lycopene and selenium with Serenoa repens was able to reduce inflammation in histological prostate sections and to further improve symptom scores and urinary flow in patients with BPH on tamsulosin treatment. Similar effects could be obtained with the use of other carotenoids, such as astaxanthin, and/or zinc. Efficacy on symptoms of patients with BPH of some polyphenols such as quercitin, equol and curcumin have been demonstrated by clinical studies. Pollen extract is a mixture of natural components able to inhibit several cytokines and prostaglandin and leukotriene synthesis resulting in a potent anti-inflammatory effect. Pollen extracts significantly improve symptoms, pain, and quality of life in patients affected by chronic pelvic pain syndrome and chronic prostatitis. Beta-sitosterol is a sterol able to improve urinary symptoms and flow measures, but not to reduce the size of the prostate gland. Palmitoylethanolamide (PEA) is an endogenous fatty acid amide-signaling molecule with anti-inflammatory and neuroprotective effects that can have an interesting role in the management of chronic pelvic pain syndrome and chronic urological pain. Finally, several plant-based products have been subjected to preclinical, in vitro and in vivo, investigations for their potential pharmacological activity against prostate cancer. Some epidemiological studies or clinical trials evaluated the effects of beverages, extracts or food preparations on the risk of prostate cancer. Some plant species deserved more intense investigation, such as Camelia sinensis (green or black tea), Solanum lycopersicum (common tomato), Punica granatum (pomegranate), Glycine max (common soy) and Linum usitatissimum (linen).

IntroductionTesticular tumors can be classified as seminomatous and non-seminomatous germ-cell tumor (NSGCT) types. Mixed germ cell tumors contain more than one germ cell component and are much more common than any of the pure histologic forms representing 32%-60% of all germ cell tumors. The composition of these tumors varies. Here we present a rare case of a mixed germ cell tumor composed of seminoma, Yolk sack tumor and teratoma containing a sarcoma component of somatic type malignancy.Case presentationA 32-year-old Caucasian male presented with history of right-sided scrotal swelling since 6 months. Backache was present since 2 months and a history of right epididimitis was also present since 8 months. Alpha-Fetoprotein, beta-HCG and LDH values were found abmormal. USG of the scrotum revealed a large right testis swelling characterized by scarce cystic elements and calcifications. CT scan of the abdomen showed nodular metastasis involving the interaortocaval, precaval, and right para-aortic lymph nodes. The block of enlarged lymph nodes infiltrated the psoas muscle. The patient underwent right-sided high orchidectomy and was given chemotherapy of the BEP regimen. After the 2nd cycle the patient discontinued the chemotherapy and when he came for follow-up after a gap of 3 months, despite the normalisation in tumor markers values, the retroperitoneal mass was relapsed. CT scan of the chest showed multiple lung metastases.ConclusionMore than 50% of germ-cell tumors include more than 2 basic germ-cell tumor types, with the exception of spermatocytic seminoma. About 90% of the patients with nonseminomatous tumors can achieve complete cure with aggressive chemotherapy and most of them can be cured. Although prognosis of testicular tumors depends largely on clinical stage, histological type and adhesion to the treatment influence the prognosis as well.

Background: The spectrum of cystic renal neoplasms includes both benign and malignant tumors and the order is as follows: benign multilocular cyst, multilocular cystic renal cell cancer and cystic renal cell cancer. Gross similarities among multicystic tumors of the kidney may cause conflict in the diagnosis and treatment of these lesions.

The frequency of clinical PC in a certain population could be related to the frequency and prevalent model of impalpable carcinoma as well as to the frequency of pre-carcinomatous lesions.
