Chronic non-bacterial prostatitis (CNP) is the most common type of prostatitis and oxidative stress (OS) was shown to be highly elevated in prostatitis patients. This study aimed to investigate the protective effect of pentoxifylline (PTX) on CNP induced by carrageenan in rats. Male adult Wistar rats (n = 30) were divided into control, CNP and three treatment groups (n = 6) including CNP + cernilton and CNP + PTX groups. CNP was induced by single intraprostatic injection of 1% carrageenan (100 µl)...

Treatments of chronic bacterial prostatitis (CP) remain difficult problem. Bacterial prostatitis is a disease entity diagnosed clinically and by evidence of inflammation and infection localized to the prostate. Risk factors for UTI in men include urological interventions, such as transrectal prostate biopsy. Ensuing infections after prostate biopsy, such as UTI and bacterial prostatitis, are increasing due to increasing rates of fluoroquinolone resistance. The increasing global antibiotic resistance also significantly affects management of UTI in men, and therefore calls for alternative strategies...

The article discusses the possible etiological factors in the development of chronic bacterial prostatitis. The authors presented a comparative long-term analysis of morbidity from non-viral sexually transmitted infections (STIs) in Russia. Against the background of general decline in STIs incidence, a significant percentage of them is made up by urogenital trichomoniasis. The findings substantiated the advantages of combination therapy (ornidazole and ofloxacin) for bacterial urinary tract infections.

Analysis of the human microbiome continues to reveal new and previously unrealized associations between microbial dysbiosis and disease. Novel approaches to bacterial identification using culture-independent methods allow practitioners to discern the presence of alterations in the taxa and diversity of the microbiome and identify correlations with disease processes. While some of these diseases that have been extensively studied are well-defined in their etiology and treatment methods (colorectal cancer), others have provided much more significant challenges in both diagnosis and treatment...

BACKGROUND: There is increasing evidence showing that chronic non-bacterial prostatic inflammation is involved in the pathogenesis of benign prostatic hyperplasia (BPH) and male lower urinary tract symptoms (LUTS). It has also been reported that estrogen receptor β (ERβ) could have an immunoprotective role in prostatic tissue. Therefore, we investigated the effect of ERβ-activation on not only prostatic inflammation, but also bladder overactive conditions in a rat model with nonbacterial prostatic inflammation...

The recovery of three stone-like ovoid objects within the burial of a pre-Mesolithic (Late Pleistocene/Early Holocene) individual at Al Khiday cemetery (Central Sudan) raises the question of the nature and origin of these objects. The position in which the objects were found in relation to the human skeleton suggested a pathological condition affecting the individual, possibly urinary bladder, kidney stones or gallstones. To solve this issue, a multi-analytical approach, consisting of tomographic, microstructural and compositional analyses, was therefore performed...

In <10% of patients with prostatitis syndrome, a causative uropathogenic organism can be detected. It has been shown that certain organisms that cause sexually transmitted infections can also cause chronic bacterial prostatitis, which can be hard to diagnose and treat appropriately because prostatic samples obtained by prostatic massage are not routinely tested to detect them. We conducted a clinical study to determine the prevalence of Chlamydia, mycoplasma, and trichomonas infection in 254 patients that were previously diagnosed and treated for chronic prostatitis/chronic pelvic pain syndrome due to negative urethral swab, urine, and prostate samples...

Prostatic abscess is a rare entity with an incidence of 0.5%-2.5% in all prostate diseases and usually occurs in the 5th and 6th decades of life with immunocompromised status. Prostatic abscess might be a process of evolution from acute prostatitis. Klebsiella pneumoniae is the leading microorganism in the diabetic patients of prostatic abscess in Taiwan. A 60-year-old diabetic man, with a one-week history of acute bacterial prostatitis was reported in this study, presenting to the emergency department with sudden altered mental status...

BACKGROUND: An infectious aetiology for prostate cancer has been conjectured for decades but the evidence gained from questionnaire-based and sero-epidemiological studies is weak and inconsistent, and a causal association with any infectious agent is not established. We describe and evaluate the application of new technology to detect bacterial and viral agents in high-grade prostate cancer tissues. The potential of targeted 16S rRNA gene sequencing and total RNA sequencing was evaluated in terms of its utility to characterise microbial communities within high-grade prostate tumours...

BACKGROUND: Chlamydia trachomatis urogenital infections are the leading cause of sexually transmitted bacterial infections. Although the prevalence of chlamydial infection is similar in men and women, current research is mainly focused on women, neglecting the study of male genital tract infections. We, therefore, investigated Chlamydia infection in the rodent male genital tract. MATERIALS AND METHODS: Male NOD and C57BL/6 mice were inoculated in the meatus urethra with C...

The recent increase in extensively drug resistant bacterial pathogens and the associated increase of morbidity and mortality demonstrate the immediate need for new antibiotic backbones with novel mechanisms of action. Here, we report the development of the PepSAVI-MS pipeline for bioactive peptide discovery. This highly versatile platform employs mass spectrometry and statistics to identify bioactive peptide targets from complex biological samples. We validate the use of this platform through the successful identification of known bioactive peptides from a botanical species, Viola odorata...

Herein we describe a novel alternative synthesis route of polyvinylpyrrolidone nanoparticles using salting-out method at a temperature close to polyvinylpyrrolidone decomposition. At elevated temperatures, the stability of polyvinylpyrrolidone decreases and the opening of pyrrolidone ring fractions occurs. This leads to cross-linking process, where separate units of polyvinylpyrrolidone interact among themselves and rearrange to form nanoparticles. The formation/stability of these nanoparticles was confirmed by transmission electron microscopy, X-ray photoelectron spectroscopy, mass spectrometry, infrared spectroscopy, and spectrophotometry...

BACKGROUND: Community-acquired bacterial meningitis due to Klebsiella pneumoniae has mainly been described in Southeast Asia and has a poor prognosis. Severe invasive infections caused by K. pneumoniae, including meningitis, are often due to hypervirulent strains (hvKP), which are characterized by capsular serotypes K1 and K2, a gene responsible for hypermucoviscosity, and the cluster for synthesis of the siderophore aerobactin. CASE PRESENTATION: A 55 year old man with a history of essential hypertension, benign prostate hyperplasia, hyperlipidemia, obstructive sleep apnea, and chronic alcoholism was admitted for meningitis due to Klebsiella pneumoniae with a wild-type susceptibility profile...

Urinary tract infections (UTIs) are one of the most important causes of morbidity and health care spending affecting persons of all ages. Bacterial biofilms play an important role in UTIs, responsible for persistent infections leading to recurrences and relapses. UTIs associated with microbial biofilms developed on catheters account for a high percentage of all nosocomial infections and are the most common source of Gram-negative bacteremia in hospitalized patients. The purpose of this mini-review is to present the role of microbial biofilms in the etiology of female UTI and different male prostatitis syndromes, their consequences, as well as the challenges for therapy...
