Interstitial cystitis is a syndrome characterized by detrusor overactivity and chronic inflammation of the bladder. The mechanisms responsible for the altered smooth muscle contractility remain poorly understood. The aim of the study was to investigate the role of intracellular signalling pathways in carbachol-induced detrusor contraction in a rat model of interstitial cystitis. Cyclophosphamide (150 mg/kg, dissolved in saline) was injected to rats (Sprague-Dawley, female, 200-250 g) intraperitoneally once a day on days 1, 4 and 7 to induce interstitial cystitis...

Interstitial cystitis (IC), also known as painful bladder syndrome (PBS), is a debilitating chronic condition that afflicts over 3 million women above the age of 18 in the U.S., and most patients fail to respond to current treatment options. Mast cells have previously been implicated as both a diagnostic and prognostic marker in IC/PBS. Patients with IC/PBS have been shown to have elevated levels of IL-33, a cytokine released in response to tissue insult, in their urine. We hypothesize that mast cell-mediated inflammation induced from IL-33 may play an important role in initiating pain and inflammation in IC/PBS...

BACKGROUND AND PURPOSE: The EMBRACE study is a prospective multi-institutional study on MRI guided adaptive brachytherapy (IGABT) in locally advanced cervix cancer (LACC). This analysis describes early to late urinary morbidity assessed by physicians and patients (PRO). MATERIAL AND METHODS: A total of 1176 patients were analysed. Median follow up (FU) was 27 (1-83) months. Morbidity (CTCAE v.3) and PRO (EORTC QLQ-C30&CX24) was prospectively assessed at baseline (BL), and during FU...

Temozolomide, a key drug in the treatment of malignant glioma, can cause profound lymphopenia and various opportunistic infectious diseases. A 79-year-old woman with anaplastic oligodendroglioma developed a fever and gross hematuria after 8 weeks of standard radiotherapy with concomitant temozolomide treatment. A cytomegalovirus (CMV) antigen test for pp65 antigenemia was positive (137 cells per 75,800 leukocytes), and the findings from a urine cytology test were consistent with CMV-induced hemorrhagic cystitis...

Objective To describe our technique utilising photoselective vaporisation of the bladder (PVB) for the management of haemorrhagic cystitis and initial results of 12 patients. Materials and Method An audit of theatre records of a single surgeon was performed to identify patients who had undergone PVB for management of radiation-cystitis. TECHNIQUE: Rigid cystoscopy was performed. Ureteric catheters were placed and active bleeding sites targeted to optimise vision. Ablation was commenced using the vaporize function...

OBJECTIVE: Hemorrhagic cystitis (HC) is a serious event that can occur after hematopoietic stem cell transplantation (HSCT). Treatment goals are primarily to preserve life, and then the functionality of the bladder. There is no standard therapeutic approach for HC. Described treatment options provide low success rates and are related to potential life-threatening side effects. The aim of this study was to describe our experience in treatment of HC following HSCT. PATIENTS AND METHODS: This was a retrospective study of patients with HC treated at our institution between January 2010 and October 2016...

OBJECTIVE: To test the hypothesis that risk factors for BPS/IC in women differ between those with and without the BPS/IC prodrome. METHODS: Incident cases of BPS/IC and healthy controls were recruited nationally. More than half the BPS/IC cases reported subsyndromal urinary symptoms for decades before onset of BPS/IC and were identified as having the prodrome. Risk factors for BPS/IC were examined separately for cases with and without the prodrome using a set of matched controls...

Omadacycline is a novel aminomethylcycline antimicrobial agent that is available in both oral and intravenous formulations. The distinguishing structural characteristics of omadacycline from other tetracyclines allow for its continued antimicrobial activity in the presence of traditional tetracycline resistance mechanisms (efflux pumps and ribosomal protection proteins). Omadacycline has been found to have potent activity against antibiotic-resistant pathogens including methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus, extended spectrum beta-lactamase-producing Escherichia coli and multidrug-resistant Streptococcus pneumoniae...

Hyperbaric oxygen therapy (HBOT) is a medical technique which delivers oxygen at ambient pressures to increase the amount of dissolved oxygen in the blood and oxygen distribution to tissues. There are several beneficial properties of HBOT concomitant with elevated oxygen distribution in tissue including anti-inflammation, angiogenesis through vascular endothelial growth factor proliferation, augmented fibroblast activity through fibroblast growth factor proliferation, tissue and wound repair, enhancement of lymphocyte and macrophage activity, increased male testosterone secretion, and bactericidal activity...

AIMS: To identify the presence and geographical distribution of mast cell (MC) subtypes: MCT (tryptase positive-chymase negative) and MCTC (tryptase positive-chymase positive) in bladder tissue. METHODS: Bladder tissue was obtained from patients with painful bladder syndrome/interstitial cystitis (n=14) and normal histology from University Hospital Southampton tissue bank. Sequential tissue slices were immunohistochemically stained for MC subtypes using anti-MC tryptase (for MCT and MCTC ) and anti-MC chymase (for MCTC )...

The present work set out to search for a virulence repertoire distinctive for Escherichia coli causing primitive acute pyelonephritis (APN). To this end, the virulence potential of 18 E. coli APN strains was genotypically and phenotypically assessed, comparatively with 19 strains causing recurrent cystitis (RC), and 16 clinically not significant (control, CO) strains. Most of the strains belong to phylogenetic group B1 (69.8%; p<0.01), and APN strains showed unique features, which are the presence of phylogroup A, and the absence of phylogroup B2 and non-typeable strains...

OBJECTIVES: To evaluate the long-term safety and efficacy of vibegron 50 mg and 100 mg, a novel β3 -adrenoreceptor agonist, in Japanese patients with overactive bladder. METHODS: This was a 1-year, multicenter, open-label, non-controlled study. After a 1-week observation phase, patients were treated with vibegron for 52 weeks. When the efficacy was insufficient after an 8-week treatment with 50 mg, the dose was increased to 100 mg and maintained for an additional 44 weeks...

The Piezo1 channel is a mechanotransduction mediator, and Piezo1 abnormalities have been linked to several clinical disorders. However, the role of the Piezo1 channel in cystitis-associated bladder dysfunction has not been documented. The current study aimed to discover the functional role of this channel in regulating bladder activity during cyclophosphamide (CYP)-induced cystitis. One hundred four female rats were randomly assigned to the control, CYP-4h, CYP-48h and CYP-8d groups. CYP successfully induced acute or chronic cystitis in these rats...

In this study, we investigated the effects of pomegranate on alleviating cyclophosphamide-induced hemorrhagic cystitis (HC). Initially, 16 Sprague-Dawley rats were allocated into 4 groups: group 1 (control), group 2 (CP) in which HC was induced by cyclophosphamide; group 3 (CP+M), HC-induced rats that received Mesna regimen, and group 4 (CP+P), which compromised rats that had been on a 14-day diet of pomegranate juice before HC induction. Cystometry was performed a few hours before euthanasia; after euthanasia, aortic blood samples and bladder tissue samples were obtained to perform TUNEL assay, and histopathologic and biochemical assessments...
