This study aims to analyze different therapeutic modalities used in the treatment of urolithiasis in the Democratic Republic of Congo. Methods: After Institutional Review Board approval, records of 194 patients who presented with documented urolithiasis in 13 hospitals across 4 provinces from January 2010 through September 2019 were retrospectively analyzed. The different layers of stones were analyzed by infrared spectrophotometry. Results: Urolithiasis was symptomatic in 52.6% (n=194) of patients. Overall, 86.1% (i.e. 167 out of 194) of stones were removed by surgery, 9.8% spontaneously resolved; 3.1% were extracted after ureteroscopy and 1% of patients had undergone extracorporeal shock wave lithotripsy. Lumbotomy was the most used route (45.2% of cases) in conventional surgery. Conclusion: Most patients in this study were treated by conventional surgery. These results suggest the need to increase the use of minimally invasive surgery.","PeriodicalId":94374,"journal":{"name":"International journal of innovative research in medical science","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135130745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similar to other chronic pain syndromes, OA pain can have a significant affective component characterized by mood changes. Serotonin (5-HT) is a neurotransmitter implicated in pain, depression, and anxiety. Pain is often in comorbidity with mood and anxiety disorders in patients with OA. Since primary actions of CBD are analgesic and anxiolytic, in this first <i>in vivo</i> positron emission tomography (PET) imaging study, we investigate the interaction of CBD with serotonin 5-HT<sub>1A</sub> receptor via a combination of <i>in vivo</i> neuroimaging and behavioral studies in a well-validated OA animal model.</p><p><strong>Methods: </strong>The first aim of this study was to evaluate the target involvement, including the evaluation of modulation by acute administration of CBD, or a specific target antagonist/agonist intervention, in control animals. The brain 5-HT<sub>1A</sub> activity/availability was assessed via <i>in vivo</i> dynamic PET imaging (up to 60 min) using a selective 5-HT<sub>1A</sub> radioligand ([<sup>18</sup>F]MeFWAY). Tracer bindings of 17 ROIs were evaluated based on averaged SUVR values over the last 10 min using CB as the reference region. We subsequently examined the neurochemical and behavioral alterations in OA animals (induction with monosodium iodoacetate (MIA) injection), as compared to control animals, via neuroimaging and behavioral assessment. Further, we examined the effects of repeated low-dose CBD treatment on mechanical allodynia (von Frey tests) and anxiety-like (light/dark box tests, L/D), depressive-like (forced swim tests, FST) behaviors in OA animals, as compared to after vehicle treatment.</p><p><strong>Results: </strong>The tracer binding was significantly reduced in control animals after an acute dose of CBD administered intravenously (1.0 mg/kg, i.v.), as compared to that for baseline. This binding specificity to 5-HT<sub>1A</sub> was further confirmed by a similar reduction of tracer binding when a specific 5-HT<sub>1A</sub> antagonist WAY1006235 was used (0.3 mg/kg, i.v.). Mice subjected to the MIA-induced OA for 13-20 days showed a decreased 5-HT<sub>1A</sub> tracer binding (25% to 41%), consistent with the notion that 5-HT<sub>1A</sub> plays a role in the modulation of pain in OA. Repeated treatment with CBD administered subcutaneously (5 mg/kg/day, s.c., for 16 days after OA induction) increased 5-HT<sub>1A</sub> tracer binding, while no significant improvement was observed after vehicle.
