Interstitial cystitis/ bladder pain syndrome (IC/BPS) is a chronic bladder condition associated with pain and voiding dysfunction that is often regarded as a neurogenic cystitis. Patient symptoms are correlated with the presence of urothelial lesions. We previously characterized a murine neurogenic cystitis model that recapitulates mast cell accumulation and urothelial lesions, and these events were dependent upon TNF. To further explore the role of TNF in bladder inflammation and function, we generated a transgenic mouse model with chronic TNF overexpression in urothelium under the control of the uroplakin II (UPII) promoter. Transgenic mouse lines were maintained by backcross onto wild-type C57BL/6J mice, and evaluated for pelvic tactile allodynia as a measure of visceral pain, urinary function and urothelial lesions. TNF mRNA and protein were expressed at greater levels in bladders of UPII-TNF mice than wild type. UPII-TNF mice showed significantly increased urinary frequency and decreased void volume. UPII-TNF mice had increased urothelial apoptosis and loss of urothelial integrity consistent with urothelial lesions. Overexpression of TNF was also associated with pelvic tactile allodynia. Consistent with these findings UPII-TNF mice exhibited increased bladder afferents activity in response to stretch ex vivo. In summary, UPII-TNF mice display significant pelvic pain, voiding dysfunction, urothelial lesions and sensory input. Thus UPII-TNF mice are a novel model for characterizing mechanisms of IC symptoms and evaluating therapies.

Stress urinary incontinence (SUI) is a condition characterized by an involuntary loss of urine occurring as result of an increase in intra-abdominal pressure due to effort or exertion or on sneezing or coughing. Estimates of its prevalence in the female population range from 10% to 40%. A literature search of the Medline, Cochrane library, EMBASE, NLH, ClinicalTrials.gov and Google Scholar databases was done up to July 2017, restricted to English-language articles, using terms related to SUI, medical therapy, surgical therapy and treatment options. The search terms included female stress urinary incontinence, mid-urethral sling, tension-free vaginal tape (TVT) and transobturator tape (TOT, TVT-O). Original articles, reviews and meta-analyses were included. Surgical therapy should be considered only after conservative therapies (e.g. an exercise programme or topical estrogens) have failed. Synthetic mid-urethral slings are the gold standard for the surgical treatment of SUI according to the 2016 guidelines of the European Society of Urology (ESU) and the 2017 position statement of the European Urogynaecological Association (EUA). The therapeutic options are numerous but further research into new therapeutic strategies is needed to achieve a better balance between efficacy and adverse events.

Ankylosing spondylitis is a chronic inflammatory disease that affects the spine and peripheral joints. Polymyalgia rheumatica is an inflammatory disease characterized by aching and prolonged morning stiffness mainly in the shoulder and pelvic girdles. Many other diseases may mimic polymyalgia rheumatica, and thus differential diagnosis is predominantly required. A wide variety of diseases, including spondyloarthropathies, may present polymyalgia-like symptoms, and two diseases rarely coexist. We present a case of a 54-year-old man who had been followed-up for ankylosing spondylitis and presented with pain in the shoulder and pelvic girdles, restricted movement, and morning stiffness for 2 months. Physical examination revealed that the pain was located mostly in the shoulder and pelvic girdles. In addition, increased erythrocyte sedimentation rate revealed the coexistence of the two diseases. Corticosteroid treatment dramatically improved the patient's symptoms and supported the diagnosis. This case demonstrated that ankylosing spondylitis may present polymyalgia-like symptoms, and the two diseases may rarely coexist in the elderly. The coexistence of these two diseases has been rarely reported in literature. Accurate diagnosis of the two diseases is essential for improving the patient's symptoms and quality of life.

Neutrophil extracellular traps (NETs) have been described to be related to the pathogenesis of inflammatory and autoimmune conditions. Endometriosis is currently considered a chronic inflammatory condition. Therefore, we performed a preliminary case-control study to compare the circulating plasma NET levels in patients with surgically confirmed endometriosis (E group, n = 82) and those of patients without surgical findings of endometriosis (C group, n = 35). Venous blood samples were obtained at the time of surgery. Circulating plasma NET levels were assessed as histone-DNA complexes (ie, nucleosomes) by a quantitative sandwich enzyme-linked immunosorbent assay. The results were expressed in arbitrary units. Circulating plasma NET levels were significantly higher in the E group compared with the C group (median [25th; 75th percentiles]): E group: 0.734 [0.484; 1.363]; C group: 0.541 [0.411; 0.653]; P = .005). The subanalysis of E group patients with deep infiltrating endometriosis (DIE group) or without DIE (non-DIE group) showed that plasma NET levels were higher in the DIE group ( P = .02). No differences were observed in NET levels among patients with and without severe pelvic pain or in patients with and without infertility, regardless of the presence of endometriotic lesions. Therefore, our study shows significantly higher NET levels in patients with endometriosis, which seem to be attributed to increased levels in the subgroup of patients with DIE, suggesting that the presence of elevated circulating plasma NET levels may reflect an inflammatory status in this gynecological condition. Further research is warranted to confirm our findings and to assess the exact role of NETs in the pathophysiological mechanisms of endometriosis.
- Small Fiber Polyneuropathy Is Prevalent in Patients Experiencing Complex Chronic Pelvic Pain. [Journal Article]
- PMPain Med 2018 Feb 13
- CONCLUSIONS: The prevalence of SFPN in our specialty referral patients with complex CPP is remarkably high vs published general population prevalence data (53/100,000). Identification of SFPN in this complex population shifts the focus from undefined syndromes to symptom complexes with linked potentially treatable mechanisms (e.g., SFPN, central sensitization). Most CPP patients with SFPN are undiagnosed. Considering the diagnosis may expand treatment options beyond conventional or so-called adjuvant analgesics. Treatment may expand to therapies such as IV lidocaine, IVIG, or other immunomodulatory options. In addition, the value to the patient of receiving a diagnosis for a multisystem or refractory pain syndrome, often attributed to negative psychologic factors, cannot be underestimated. Identifying SFPN should be contemplated in CPP patients who present with multisystem pain or who have not responded to initial evaluation and management.

Deep infiltrating endometriosis (DIE) is the most severe form of endometriosis. It causes chronic pelvic pain, severe dysmenorrhea, deep dyspareunia, dyschezia, and dysuria, markedly impairing the quality of life of women of reproductive age. A number of randomized controlled trials on surgical and medical treatments to reduce the pain associated with endometriosis have been reported, but few have focused on this in DIE. DIE causes not only pain but also functional invasion to the urinary organs and bowel, such as hydronephrosis and bowel stenosis. In addition to DIE resection, surgical treatment involves adhesion separation as well as resection and reconstruction of the urinary organs and bowel; high-level skills are required. The severity of DIE should be evaluated preoperatively as accurately as possible. Using ENZIAN in conjunction with the AFS (The revised American Fertility Society classification of endometriosis) classification makes a more detailed assessment of DIE possible. The operative procedures used for laparoscopic resection of urinary DIE and reconstruction of the urinary organs are chosen based on the type of lesion (intrinsic/extrinsic) and length of stenosis. In addition to ureteroneocystostomy, the psoas bladder hitch and Boari bladder flap procedures are applied when necessary to extend the urinary tract. Bowel resection for bowel endometriosis is classified into classic segmental resection and conservative approaches (shaving/discoid). When these procedures are employed, it is advisable to work in consultation with urologists and gastroenterologists and to inform the patients of the associated risks and outcomes. Furthermore, postoperative medication is essential because it is difficult to conduct repeated surgeries.

Pain is the most reported and troublesome symptom of nearly all functional disorders affecting the genitourinary and gastrointestinal organs. Patients with irritable bowel syndrome (IBS), interstitial cystitis/painful bladder syndrome (IC/PBS), vulvodynia, and/or chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS; collectively termed chronic pelvic pain syndromes) report pain severe enough to impact quality of life and often suffer from symptoms of or are diagnosed with more than one of these syndromes. This increased comorbidity between chronic pelvic pain syndromes, and with pain disorders of disparate body regions, as well as with mood disorders, can be influenced by disruptions in the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the response to stress and influences the perception of pain. Experiencing trauma, neglect, or abuse in early life can permanently affect the functioning of the HPA axis. As such, a significant proportion of patients suffering from comorbid chronic pelvic pain syndromes report a history of early life stress or trauma. Here we will report on how these early life experiences influence chronic pelvic pain in patients. We will also discuss various rodent models that have been developed to study this phenomenon to understand the mechanisms underlying HPA axis dysfunction, as well as potential underlying mechanisms connecting these syndromes to one another.
