[Dysmenorrhea and pelvic pain secondary to an accessory and cavitated uterine mass]. / Dysménorrhée et douleurs pelviennes secondaires à une masse utérine cavitaire accessoire.

An accessory and cavitated uterine mass (ACUM) is a rare anomaly with an embryological origin of dysfunctionning female gubernaculum. It is an accessory mass internally lined with normal endometrium, separated from the uterine cavity and located near the insertion of the round ligament. ACUM's clinical manifestations are severe dysmenorrhea and/or chronic pelvic pain. It is a relatively unknown condition, which makes its diagnosis complicated and suggests a large differential diagnosis. We report the case of a 31-year-old female presenting with pelvic chronic pain and crippling dysmenorrhea. The initial work-up consists of a magnetic resonance imaging showing an interstitial lesion possibly corresponding to an ACUM. This supposition was then confirmed by histopathology.

La masse utérine cavitaire accessoire (MUCA) est une anomalie rare dont l'origine est embryologique et serait liée à un dysfonctionnement du gubernaculum féminin. Il s'agit d'une masse accessoire non communicante située à proximité de l'insertion du ligament rond, tapissée par un endomètre normal. La MUCA se manifeste par une dysménorrhée sévère et/ou des douleurs pelviennes chroniques. Il s'agit d'une pathologie relativement méconnue, ce qui rend son diagnostic difficile, et qui suggère un large diagnostic différentiel. Nous rapportons ici le cas d'une femme de 31 ans présentant des douleurs pelviennes chroniques et une dysménorrhée invalidante. La mise au point initiale par résonance magnétique pelvienne a montré la présence d'une lésion interstitielle pouvant correspondre à une MUCA, qui a ensuite été confirmée à l'examen histopathologique.

The role of CD8+ T cells in endometriosis: a systematic review.

Background: Endometriosis is a chronic disease affecting 6-10% of women of reproductive age. It is an important cause of infertility and chronic pelvic pain with poorly understood aetiology. CD8+ T (CD8 T) cells were shown to be linked to infertility and chronic pain and play a significant role in lesion clearance in other pathologies, yet their function in endometriosis is unknown. We systematically evaluated the literature on the CD8 T in peripheral blood and endometriosis-associated tissues to determine the current understanding of their pathophysiological and clinical relevance in the disease and associated conditions (e.g. infertility and pelvic pain). Methods: Four databases were searched (MEDLINE, EMBASE, Web of Science, CINAHL), from database inception until September 2022, for papers written in the English language with database-specific relevant terms/free-text terms from two categories: CD8 T cells and endometriosis. We included peer-reviewed papers investigating CD8 T cells in peripheral blood and endometriosis-associated tissues of patients with surgically confirmed endometriosis between menarche and menopause, and animal models with oestrous cycles. Studies enrolling participants with other gynaecological pathologies (except uterine fibroids and tubal factor infertility used as controls), cancer, immune diseases, or taking immune or hormonal therapy were excluded. Results: 28 published case-control studies and gene set analyses investigating CD8 T cells in endometriosis were included. Data consistently indicate that CD8 T cells are enriched in endometriotic lesions in comparison to eutopic endometrium, with no differences in peripheral blood CD8 T populations between patients and healthy controls. Evidence on CD8 T cells in peritoneal fluid and eutopic endometrium is conflicting. CD8 T cell cytotoxicity was increased in the menstrual effluent of patients, and genomic analyses have shown a clear trend of enriched CD8 T effector memory cells in the eutopic endometrium of patients. Conclusion: Literature on CD8 T cells in endometriosis-associated tissues is inconsistent. Increased CD8 T levels are found in endometriotic lesions, however, their activation potential is understudied in all relevant tissues. Future research should focus on identifying clinically relevant phenotypes to support the development of non-invasive diagnostic and treatment strategies. Systematic Review Registration: PROSPERO identifier CRD42021233304.

Definition and Criteria for Diagnosing Cesarean Scar Disorder.

Importance: Approximately 60% of women develop a uterine niche after a cesarean delivery (CD). A niche is associated with various gynecological symptoms including abnormal uterine bleeding, pain, and infertility, but there is little consensus in the literature on the distinction between the sonographic finding of a niche and the constellation of associated symptoms. Objective: To achieve consensus on defining the clinical condition that constitutes a symptomatic uterine niche and agree upon diagnostic criteria and uniform nomenclature for this condition. Design, Setting, and Participants: A consensus based modified electronic Delphi (eDelphi) study, with a predefined Rate of Agreement (RoA) of 70% or higher. Experts were selected according to their expertise with niche-related consultations, publications, and participation in expert groups and received online questionnaires between November 2021 and May 2022. Main Outcomes and Measures: Definition, nomenclature, symptoms, conditions to exclude, and diagnostic criteria of an illness caused by a symptomatic uterine niche. Results: In total, 31 of the 60 invited experts (51.7%) participated, of whom the majority worked in university-affiliated hospitals (28 of 31 [90.3%]), specialized in benign gynecology (20 of 31 [64.5%]), and worked in Europe (24 of 31 [77.4%]). Three rounds were required to achieve consensus on all items. All participants underlined the relevance of a new term for a condition caused by a symptomatic niche and its differentiation from a sonographic finding only. Experts agreed to name this condition cesarean scar disorder, defined as a uterine niche in combination with at least 1 primary or 2 secondary symptoms (RoA, 77.8%). Defined primary symptoms were postmenstrual spotting, pain during uterine bleeding, technical issues with catheter insertion during embryo transfer, and secondary unexplained infertility combined with intrauterine fluid. Secondary symptoms were dyspareunia, abnormal vaginal discharge, chronic pelvic pain, avoiding sexual intercourse, odor associated with abnormal blood loss, secondary unexplained infertility, secondary infertility despite assisted reproductive technology, negative self-image, and discomfort during participation in leisure activities. Consensus was also achieved on certain criteria that should be met and conditions that should be excluded before making the diagnosis. Conclusions and Relevance: In this modified Delphi study, a panel of 31 international niche experts reached consensus for the constellation of symptoms secondary to a uterine niche and named it cesarean scar disorder.

[Groin pain in athletes-sportsmen's groin]. / Sportlerleiste ­ "Sportsmen's groin".

CLINICAL/METHODICAL ISSUE: Groin pain in athletes can have various causes. Radiologically, osteitis pubis and clefts with affection of the interpubic disc as well as muscle and tendon tears near the pubic bone can be clearly identified. STANDARD RADIOLOGICAL METHODS: Magnetic resonance imaging (MRI) is the imaging modality of choice, as well as single-leg stand imaging (flamingo view radiographs), and where appropriate symphysography. METHODICAL INNOVATIONS: Optimized MRI sequence protocol with oblique (axial oblique) slices parallel to the linea arcuata of the iliac bone is recommended. High-resolution MRI sequences and symphysography can detect superior and secondary cleft formation. Instabilities of the pubic symphysis can be diagnosed using flamingo view radiographs. PERFORMANCE: The MRI findings of osteitis pubis and clinical symptoms correlate. The presence of parasymphyseal bone marrow edema is the earliest morphological sign of acute osteitis pubis on MR imaging. Edema in the periosteal tissue and isolated muscle lesions next to the symphysis are generally associated with more severe clinical symptoms. ACHIEVEMENTS AND PRACTICAL RECOMMENDATIONS: Close communication between radiologists and the referring physicians is indispensable when planning an adequate imaging protocol, and precise knowledge of the clinical symptoms in the case of clinical suspicion of osteitis pubis allows for a reliable diagnosis and provides important prognostic information.

Diagnostic and therapeutic cystoscopy in bladder pain syndrome/interstitial cystitis: systematic review of literature and consensus on methodology.

INTRODUCTION AND HYPOTHESIS: Cystoscopy has been routinely performed in patients suspected to be suffering from bladder pain syndrome/interstitial cystitis (BPS/IC) across the globe. The methodology reported by various guidelines appears to have differences in the techniques and hence there is a need for a review of all those techniques in order to arrive at a consensus. The aim was to review the literature describing the prevalent techniques of cystoscopy for patients of BPS/IC and try to evolve a consensus. METHODS: The group the Global Interstitial Cystitis, Bladder Pain Society (GIBS) has worked collectively to systematically review the literature using the key words, "Cystoscopy in Hunner's lesions, bladder pain syndrome, painful bladder syndrome and interstitial cystitis" in the PubMed, COCHRANE, and SCOPUS databases. A total of 3,857 abstracts were studied and 96 articles referring to some part of technique of cystoscopy were short-listed for review as full-length articles. Finally, six articles with a description of a technique of cystoscopy were included for final tabulation and comparison. The group went on to arrive at a consensus for a stepwise technique of diagnostic and therapeutic cystoscopy in cases of BPS/IC. This technique has been compared with the previously described techniques and may serve to be a useful practical guide for treating physicians. CONCLUSION: It is important to have a uniform standardized technique for performing a diagnostic and therapeutic cystoscopy in patients with BPS/IC. Consensus on one such a technique has been arrived at and described in the present article.

Abnormal prostate microbiota composition is associated with experimental autoimmune prostatitis complicated with depression in rats.

Background: Microbiota play essential roles in the pathogenesis of prostatitis and depression. However, the changes in prostate microbiota have not yet been explored in rats with prostatitis/depression. This study aimed to investigate the changes of prostate microbiota in rats with prostatitis/depression. Methods: Rats with experimental autoimmune prostatitis (EAP) complicated with depression were constructed through injection of rat prostate antigen with immunoadjuvants followed by application of chronic unpredictable mild stress (CUMS). The rats were subjected to inflammatory factor detection and behavioral testing to confirm the establishment of the model. Subsequently, the prostate microbiota was assayed in the rats and compared by 16S rRNA gene sequencing. Results: A rat model of EAP complicated with depression was established and confirmed by increases in IL-1ß, IL-6, and TNF-α as well as the occurrence of depressive-like behaviors. EAP/CUMS significantly altered the richness, evenness, and composition of prostate microbiota. Forty-six taxonomic biomarkers for prostate microbiota were enriched in rats with EAP/depression and exhibited statistically significant and biologically consistent differences. Metabolomics profiling revealed that EAP/depression was associated with reductive acetyl coenzyme A pathway, L-lysine fermentation to acetate and butanoate, protein N-glycosylation and purine nucleobases degradation I, which is regulated by DCE29, Nocardioes, Helicobacter and Dorea. Conclusion: Findings from the study demonstrate the existence of abnormal prostate microbiota in EAP complicated with depression and may be helpful in the treatment of comorbid diseases of prostatitis and depression.

Cracking the enigma of adenomyosis: an update on its pathogenesis and pathophysiology.

In brief: Traditionally viewed as enigmatic and elusive, adenomyosis is a fairly common gynecological disease but is under-recognized and under-researched. This review summarizes the latest development on the pathogenesis and pathophysiology of adenomyosis, which have important implications for imaging diagnosis of the disease and for the development of non-hormonal therapeutics. Abstract: Traditionally considered as an enigmatic disease, adenomyosis is a uterine disease that affects many women of reproductive age and is a contributing factor for pelvic pain, heavy menstrual bleeding (HMB), and subfertility. In this review, the new development in the pathogenesis and pathophysiology of adenomyosis has been summarized, along with their clinical implications. After reviewing the progress in our understanding of the pathogenesis and describing the prevailing theories, in conjunction with their deficiencies, a new hypothesis, called endometrial-myometrial interface disruption (EMID), which is backed by extensive epidemiologic data and demonstrated by a mouse model, is reviewed, along with recent data implicating the role of Schwann cells in the EMI area in the genesis of adenomyosis. Additionally, the natural history of adenomyotic lesions is elaborated and underscores that, in essence, adenomyotic lesions are fundamentally wounds undergoing repeated tissue injury and repair (ReTIAR), which progress to fibrosis through epithelial-mesenchymal transition, fibroblast-to-myofibroblast transdifferentiation, and smooth muscle metaplasia. Increasing lesional fibrosis propagates into the neighboring EMI and endometrium. The increased endometrial fibrosis, with ensuing greater tissue stiffness, results in attenuated prostaglandin E2, hypoxia signaling and glycolysis, impairing endometrial repair and causing HMB. Compared with adenomyosis-associated HMB, the mechanisms underlying adenomyosis-associated pain are less understood but presumably involve increased uterine contractility, hyperinnervation, increased lesional production of pain mediators, and central sensitization. Viewed through the prism of ReTIAR, a new imaging technique can be used to diagnose adenomyosis more accurately and informatively and possibly help to choose the best treatment modality.

HA/CD44 Regulates the T Helper 1 Cells Differentiation by Activating Annexin A1/Akt/mTOR Signaling to Drive the Pathogenesis of EAP.

CD44 partcipates in multiple inflammatory reactions. Here, we aimed to investigate the role of CD44 and the ligand, hyaluronan (HA), on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) pathogenesis. We found that CD44 was universally expressed in CD4+ lymphocytes in the peripheral blood of CP/CPPS patients. After silencing CD44 expression or delivering 4-methylumbelliferone (4-MU), the pain severity and prostatic inflammation were significantly relieved. In vitro assay found that HA/CD44 was able to regulate T helper 1 (Th1) cells differentiation, the deficiency of which diminished experimental autoimmune prostatitis (EAP) susceptibility. Bioinformatic analysis suggested that after HA or 4-MU treatment, mTOR signaling was significantly altered, and these results were confirmed by subsequent Western blotting assay. Besides, mass spectrometry and co-immunoprecipitation assays found that CD44 was able to interact with Annexin A1 (ANX A1), and this kind of interaction stabilized ANX A1 protein and maintained the activation of Akt/mTOR pathway. Meanwhile, HA-treatment-enhanced prostatic inflammation, Th1 cell differentiation, and Akt/mTOR pathway activation were reversed after silencing the expression of ANX A1 using shANX A1-lentivirus. The present study systematically investigates the functional role of HA/CD44 in CP/CPPS and identifies novel mechanisms for HA/CD44 promoting Th1 cell differentiation. Targeting the HA/CD44/ANX A1/Akt/mTOR signaling represents novel potential therapeutic strategies for patients with CP/CPPS.

The Promises of Natural Killer Cell Therapy in Endometriosis.

Endometriosis is a gynaecological disease defined by the growth of endometrium-like tissue outside the uterus. The disease is present in approximately 5-10% of women of reproductive age and causes pelvic pain and infertility. The pathophysiology is not completely understood, but retrograde menstruation and deficiency in natural killer (NK) cells that clear endometriotic cells in the peritoneal cavity play an important role. Nowadays, hormonal therapy and surgery to remove endometriosis lesions are used as treatment. However, these therapies do not work for all patients, and hormonal therapy prevents patients from getting pregnant. Therefore, new treatment strategies should be developed. Since the cytotoxicity of NK cells is decreased in endometriosis, we performed a literature search into the possibility of NK cell therapy. Available treatment options include the inhibition of receptor-ligand interaction for KIR2DL1, NKG2A, LILRB1/2, and PD-1/PD-L1; inhibition of TGF-ß; stimulation of NK cells with IL-2; and mycobacterial treatment with BCG. In preclinical work, these therapies show promising results but unfortunately have side effects, which have not specifically been studied in endometriosis patients. Before NK cell treatment can be used in the clinic, more research is needed.

Distribution of the positive UPOINT domain in patients with chronic prostatitis or chronic pelvic pain syndrome: A multicenter observational study.

OBJECTIVE: To determine the UPOINT-positive domain numbers and evaluate the significance of the sexual dysfunction domain in patients with chronic prostatitis or chronic pelvic pain (CP/CPPS) in Japan. METHODS: A total of 58 patients with CP/CPPS with moderate or greater symptoms were included. Symptom severity was determined by > 14 on the chronic prostatitis symptom index (CPSI). The main outcome was to confirm the number and distribution of the positive UPOINT domains in this group. As secondary outcomes, the correlation between positive domain numbers and CPSI scores was evaluated. We also examined whether the sexual dysfunction subdomain, as determined by the five-item international index of erectile function, could improve the correlation with symptom severity. RESULTS: The mean age was 48.6 ± 15.4 years, CPSI score 24.3 ± 6.1, and positive UPOINT domain number 2.4 ± 0.9. The distribution of each positive domain was 67.2% for urinary, 15.5% for psychosocial, 75.8% for organ-specific, 3.4% for infection, 5.1% for neurological/systemic conditions, and 75.8% for tenderness. Although the mean CPSI total scores tended to increase with an increasing number of positive UPOINT domains, a significant correlation was not observed (r = 0.134, p = 0.312). The sexual dysfunction domain was positive in 62.0% of the cases, but the correlation could not be improved. CONCLUSIONS: Urinary, organ specific, and tenderness domains were mainly observed in patients with CP/CPPS. When patients with moderate or grater CPSI scores are clinically evaluated, clinicians should recognize that the UPOINT-positive domain and CPSI score are clinically and pathologically different concepts.

Effect of thermophilic bacterium HB27 manganese superoxide dismutase in a rat model of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

We investigated the therapeutic effects of superoxide dismutase (SOD) from thermophilic bacterium HB27 on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and its underlying mechanisms. A Sprague-Dawley rat model of CP/CPPS was prepared and then administered saline or Thermus thermophilic (Tt)-SOD intragastrically for 4 weeks. Prostate inflammation and fibrosis were analyzed by hematoxylin and eosin staining, and Masson staining. Alanine transaminase (ALT), aspartate transaminase (AST), serum creatinine (CR), and blood urea nitrogen (BUN) levels were assayed for all animals. Enzyme-linked immunosorbent assays (ELISA) were performed to analyze serum cytokine concentrations and tissue levels of malondialdehyde, nitric oxide, SOD, catalase, and glutathione peroxidase. Reactive oxygen species levels were detected using dichlorofluorescein diacetate. The messenger ribonucleic acid (mRNA) expression of tissue cytokines was analyzed by reverse transcription polymerase chain reaction (RT-PCR), and infiltrating inflammatory cells were examined using immunohistochemistry. Nuclear factor-κB (NF-κB) P65, P38, and inhibitor of nuclear factor-κBα (I-κBα) protein levels were determined using western blot. Tt-SOD significantly improved histopathological changes in CP/CPPS, reduced inflammatory cell infiltration and fibrosis, increased pain threshold, and reduced the prostate index. Tt-SOD treatment showed no significant effect on ALT, AST, CR, or BUN levels. Furthermore, Tt-SOD reduced inflammatory cytokine expression in prostate tissue and increased antioxidant capacity. This anti-inflammatory activity correlated with decreases in the abundance of cluster of differentiation 3 (CD3), cluster of differentiation 45 (CD45), and macrophage inflammatory protein 1α (MIP1α) cells. Tt-SOD alleviated inflammation and oxidative stress by reducing NF-κB P65 and P38 protein levels and increasing I-κBα protein levels. These findings support Tt-SOD as a potential drug for CP/CPPS.

B6 Mouse Strain: The Best Fit for LPS-Induced Interstitial Cystitis Model.

Interstitial cystitis (IC) is a chronic inflammatory disease characterized by bladder pain and increased urinary frequency. Although the C57BL/6J (B6) and FVB/NJ (FVB) mouse strains are commonly used as animal models for studies involving the urinary system, few reports have compared their lower urinary tract anatomy, despite the importance of such data. Our study aimed to characterize bladder function changes in FVB and B6 mouse strains with lipopolysaccharide (LPS)-induced IC, to understand mouse model-based bladder research. The bladder function parameters were measured by cystometrogram. Histological assay was examined by hematoxylin and eosin stain, Masson's trichrome stain, and immunofluorescence staining. Results indicated that the two strains in the control group exhibited different bladder structures and functions, with significant anatomical differences, including a larger bladder size in the FVB than in the B6 strain. Furthermore, cystometry tests revealed differences in bladder function pressure. LPS-treated B6 mice presented significant changes in peak pressure, with decreased intercontraction intervals; these results were similar to symptoms of IC in humans. Each strain displayed distinct characteristics, emphasizing the care required in choosing the appropriate strain for bladder-model studies. The results suggested that the B6 mouse strain is more suitable for IC models.

Interstitial cystitis/bladder pain syndrome patient is associated with subsequent increased risks of outpatient visits and hospitalizations: A population-based study.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is not only a chronic urinary bladder pain syndrome but is also associated with multifactorial etiology. Our study aimed to test the hypothesis that IC/BPS is associated with subsequent increased risks of outpatient visits and hospitalizations. Using nationwide database, the diagnoses were based on the International Classification Codes (ICD-9-CM) (595.1) of at least three outpatient services during 2002-2008, (n = 27,990) and cystoscopic finding Hunner type and/or glomerulation with pre-audit criteria. All recruited cases monitored for subsequent outpatient visits and hospitalizations for 2 years, including all-cause and specialty-specific departments, were classified according to medical specialty and age group (<40, 40-60, ≥60 years of age). IC/BPS patients have more overall outpatient department (OPD) visits and an overall adjusted incidence rate ratio (IRR) of 1.64. As for specialty, IRRs were higher in psychiatry (2.75), Chinese medicine (2.01), and emergency medicine (2.00), besides urology and gynecology. The IRRs decreased as age advanced (2.01, 1.71, and 1.44, respectively), except for gynecology (2.42, 2.52, and 2.81). A similar phenomenon happens in hospitalization with IRR of 1.69. Due to claim data characteristics, whether ulcer type IC/BPS findings can be deductive to non-ulcer type remains inclusive. Current results indicate the impacts of healthcare burden in broad spectrum about IC/PBS patients. IC/BPS has been suggested to be associated with lower threshold of healthcare visits and some coexisting disease and is comprised of systemic dysregulation, and is beyond the scope of local bladder-urethra disease. Adequate recognition of associated or comorbid factors and possible recommendation or referral for IC/BPS patients can help provide better healthcare quality.

Herniation Through Defects in the Broad Ligament.

BACKGROUND: We sought to assess hernia characteristics and classification through comprehensive review of the literature involving broad ligament herniation. METHODS: A literature search via MEDLINE and Embase databases was conducted to identify and select broad ligament herniation studies published between January 1, 2000 and September 30, 2020. Extracted data included previous surgical history, previous obstetric history, diagnostic imaging, herniated organ, hernia classification, and repair performed. The reported data has been compared to a unique case of broad ligament herniation that presented to our institution. RESULTS: A total of 44 articles with 49 cases were identified for the study. Eighteen (36.7%) patients had a history of previous abdominal surgery while 29 (59.2%) had a history of previous childbirth. Type I (51.0%) and Type II (18.4%) defects were most commonly reported with most patients reporting only one defect (85.7%) using the Cilley classification. Twenty-nine patients underwent primary laparoscopic repair of the defect while 19 patients underwent exploratory laparotomy. CONCLUSIONS: The analysis of previously reported cases adds to the limited literature on broad ligament hernias and highlights the surgical management of this uncommon pathology. It also highlights the need for a broad differential diagnosis when female patients present with pelvic pain or symptoms of small bowel obstruction. The broad ligament should be fully inspected when mesenteric defects are suspected as multiple defects can be present as evidenced by the attached case study.

Interstitial Cystitis/Bladder Pain Syndrome's Correlations with Pregnancy and Neonatal Outcomes: A Study of a Population Database.

PURPOSE: Our objective was to evaluate the associations with interstitial cystitis during pregnancy using a United States inpatient database. MATERIALS AND METHODS: We conducted a retrospective cohort study utilizing the Nationwide Inpatient Sample database from the Healthcare Cost and Utilization Project. ICD-9 code number 595.1 was used to extract cases of chronic interstitial cystitis and these pregnancies were compared to pregnancies without chronic interstitial cystitis, using the Chi-squared test to evaluate nominal variables. A multivariate logistic regression model was subsequently used to adjust for statistically significant confounders (p value <0.05). RESULTS: There were 9,095,995 deliveries during the study period; 793 pregnant women were found to have chronic interstitial cystitis. When controlling for confounding effects in terms of pregnancy outcomes, the diagnosed group had a greater risk of developing pregnancy-induced hypertension (adjusted OR 1.57, 95% CI 1.21-2.05), preeclampsia (adjusted OR 2.06, 95% CI 1.47-2.87), preterm delivery (adjusted OR 1.63, 95% CI 1.23-2.17), preterm premature rupture of membranes (adjusted OR 2.18, 95% CI 1.25-3.79), chorioamnionitis (adjusted OR 2.05, 95% CI 1.24-3.37), delivery via cesarean section (adjusted OR 1.57, 95% CI 1.32-1.88), maternal infection (adjusted OR 2.19, 95% CI 1.40-3.43), and deep venous thromboembolism (adjusted OR 10.56, 95% CI 3.37-33.09). CONCLUSIONS: Interstitial cystitis diagnosis is associated with an increased risk of preeclampsia, preterm birth, and other adverse pregnancy outcomes in this database study. Prospective studies are required to confirm the findings of the correlation between interstitial cystitis and adverse pregnancy outcomes.

Characteristics of the spinopelvic parameters of patients with sacroiliac joint pain.

To evaluate the characteristics of the spinopelvic parameters on radiography in patients with sacroiliac joint pain (SIJP). Two hundred fifty patients were included and divided into the SIJP group (those diagnosed with SIJP based on physical findings and response to analgesic periarticular injections; n = 53) and the non-SIJP group (those with low back pain [LBP] because of other reasons; n = 197). We compared their demographic characteristics and spinopelvic parameters using radiography. All differences found in the patients' demographic characteristics and spinopelvic parameters were analyzed. More female participants experienced SIJP than male participants (P = 0.0179). Univariate analyses revealed significant differences in pelvic incidence (PI) (P = 0.0122), sacral slope (SS) (P = 0.0034), and lumbar lordosis (LL) (P = 0.0078) between the groups. The detection powers for PI, SS, and LL were 0.71, 0.84, and 0.66, respectively. Logistic regression analyses, after adjustment for age and sex, revealed significant differences in PI (P = 0.0308) and SS (P = 0.0153) between the groups, with odds ratios of 1.03 and 1.05, respectively. More female participants experienced SIJP than male participants. Higher PI and SS values were related to SIJP among LBP patients.

Immunological alterations in patients with chronic prostatitis/chronic pelvic pain syndrome and experimental autoimmune prostatitis model: A systematic review and meta-analysis.

BACKGROUND: As one of the most common conditions in urological outpatients, chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) puzzles many individuals because of its unclear etiology and lack of effective treatment. Recently, immunological alterations underpinning CP/CPPS have been extensively investigated. METHODS: The PubMed, Web of Science, Cochrane library, and EMBASE databases were used to search original articles on immune mediators in patients with CP/CPPS and in experimental autoimmune prostatitis (EAP) models through April 10, 2020. Standardized mean differences (SMD) were calculated to summarize the differences in immune mediator levels between groups. Funnel plot, Begg's funnel plot, Egger's regression test, and the sensitivity analysis were applied to determine and visualize the stability of our findings. RESULTS: A total of 34 original studies were included in the meta-analysis, including 24 studies on patients with CP/CPPS and 10 studies on EAP models. We found that TNF-α, IL-1ß, IL-6, and IL-8 were the four immune mediators that elevated in most of the samples derived from patients with CP/CPPS and the EAP models. The adjusted publication bias analysis indicated that publication bias was not existed, and the sensitivity analyses showed that the results were stable. CONCLUSIONS: Immune responses play significant roles during the pathogenesis of CP/CPPS by promoting intraprostatic inflammation. Our findings provide potential diagnostic and therapeutic targets for CP/CPPS patients.

Dienogest reduces endometrioma volume and endometriosis-related pain symptoms.

This study aimed to evaluate the efficacy and adverse effects of dienogest for the treatment of endometriomas. Dienogest (2 mg/day) was administered to patients with endometrioma continuously through the 6-month study period. The patients were prospectively examined on the efficacy and side effects at baseline, at third months, and sixth months of the treatment. Twenty-four out of 30 patients were able to complete the study. The mean volume of the endometrioma decreased significantly from 112.63 ± 161.31 cm³ at baseline to 65.47 ± 95.69 cm³ at a 6-month follow-up (-41%) (p = .005). The VAS score for pelvic pain decreased significantly from 7.50 to 3.00 (p < .001) at the sixth months of treatment. The most common side effects were menstrual irregularities. Laboratory parameters did not change during the study. Dienogest considered being effective for 6 months of use in decreasing the size of endometrioma, reducing endometriosis-associated pain with a favourable safety and tolerability profile.Impact statementWhat is already known on this subject? Laparoscopic excisional surgery for endometrioma is currently the most valid approach in the treatment of endometriomas. However, there are concerns about ovarian reserve damage during surgery.What do the results of this study add? Dienogest considered being effective in decreasing the size of endometrioma, reducing endometriosis-associated pain with a favourable safety and tolerability profile. Long-term use of dienogest in younger patients with endometriomas who are yet to give birth may reduce the possibility of surgery by reducing the size of the endometriomas and may preserve ovarian reserve.What are the implications of these findings for clinical practice and/or further research? Dienogest may reduce the incidence of infectious complications such as pelvic abscess after oocyte retrieval and the surgical procedures in infertile patients with endometrioma.

Extracorporeal shock wave therapy decreases the number of total and degranulated mast cells and alleviates pelvic pain in a rat model of prostatitis.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common male urological disease characterized by chronic pelvic pain. Extracorporeal shock wave therapy (ESWT) has been used to treat patients with CP/CPPS, but the parameters used by ESWT are not uniformly determined. Herein, this study aims to assess the effects of ESWT with different energy flux densities on pelvic pain in CP/CPPS rats and to explore the mechanisms. A rat model of CP/CPPS was induced by intraprostatic injection of 1% carrageenan. ESWT with different energy flux densities (0.09, 0.20, 0.30, 0.40 mJ/mm2) was applied in the pelvic region of CP/CPPS rats once a week for 4 weeks. The results showed that compared with the other energy flux densities (0.09, 0.30, and 0.40 mJ/mm2), ESWT with 0.20 mJ/mm2 exhibited a more powerful effect in alleviating pelvic pain and prostate damage. The therapeutic effect is associated with the reduction of the number of total and degranulated mast cells. Collectively, ESWT with 0.20 mJ/mm2 achieved the optimal therapeutic effect in alleviating pelvic pain in CP/CPPS rats.

Negative Sliding Sign during Dynamic Ultrasonography Predicts Low Endometriosis Fertility Index at Laparoscopy.

STUDY OBJECTIVE: Endometriosis fertility index (EFI) is a robust tool to predict the pregnancy rate in patients with endometriosis who are attempting non-in vitro fertilization conception. However, EFI calculation requires laparoscopy. Newly established imaging techniques such as sliding sign, which is used to diagnose pouch of Douglas obliteration, could provide a promising alternative. The objective of this study was to investigate the practicality of using ultrasound data to predict a low EFI (score ≤6). DESIGN: Observational study from a prospective registry (Endometriosis Pelvic Pain Interdisciplinary Cohort, clinicaltrials.gov #NCT02911090). Analyzed data were captured from December 2013 to June 2017. SETTING: Tertiary referral center at British Columbia Women's Hospital. PATIENTS: We analyzed data for 2583 participants from the Endometriosis Pelvic Pain Interdisciplinary Cohort. In this cross-sectional study, we included 86 women aged <40 years. INTERVENTIONS: Dynamic ultrasonography for the sliding sign testing and EFI calculation during laparoscopic surgery. MEASUREMENTS AND MAIN RESULTS: Logistic regression was used to obtain receiver operating characteristic area under the curve (AUC) for the prediction models. Significance was p <.05. Patients with a negative sliding sign were older and had severe endometriosis and longer duration of infertility. Patients with a negative sliding sign had significantly lower total EFI scores and lower surgical factors scores than patients with a positive sliding sign. Logistic regression showed that a negative sliding sign and EFI historic factors score can predict an EFI score ≤6 (sensitivity = 87.9%, specificity = 81.1%, AUC = 0.93 [95% confidence interval, 0.88-0.98]). Adding the diagnosis of endometrioma to the previous prediction model resulted in AUC = 0.95 (95% confidence interval, 0.90-0.995), sensitivity = 84.8%, and specificity = 92.5%. CONCLUSION: The sliding sign could be a potential alternative to the EFI surgical factors, and it could be used in combination with EFI historic factors and the diagnosis of endometrioma to predict an EFI score ≤6 for patients who are not scheduled for immediate surgery.
