Background: Urinary incontinence is defined as the involuntary loss of urine, which can affect up to 45% of women after menopause. Radiofrequency is a non-invasive procedure that involves the application of an electromagnetic wave that through heat generation promotes neocollagenesis and neoeslatinogenesis in the vaginal epithelium. This energy-based technology has been studied as a potential alternative for the treatment of genitourinary syndrome of menopause and urinary incontinence. Objective: To review the recent literature (from 2020 to June 2022) on the use of transvaginal radiofrequency in the treatment of stress urinary incontinence, by searching articles at databases of Capes, PubMed Cochrane and Scielo. Methods: The descriptor terms “Urinary Incontinence/therapy” [Majr] AND “Urinary Incontinence, Stress/therapy” [Majr] AND RADIOFREQUENCY-Search Results-PubMed, [“woman” OR “women”] AND [“urinary incontinence” OR “stress urinary incontinence”] AND Radiofrequency were used, with a filter for the period 2020 to 2022. Conclusion: The studies evaluated in this review demonstrated significant results of radiofrequency in the resolution or reduction of complaints of women with urinary incontinence, especially stress urinary incontinence, but most of these studies presented a low methodological quality. There is, therefore, a lack of studies with longer follow-ups, evaluation of cost-effectiveness, randomized clinical trials with objective outcomes and the use of validated questionnaires with international acceptance.

AIM:To investigate the effects of titanium dioxide (TiO2) nanoparticles (NPTiO 2 ) and microparticles (MPTiO 2 ) on the inflammatory response in the small intestine of mice. METHODS: Bl 57/6 male mice received distilled water suspensions containing TiO 2 (100 mg/kg body weight) as NPTiO 2 (66 nm), or MPTiO 2 (260 nm) by gavage for 10 d, once a day; the control group received only distilled water. At the end of the treatment the duodenum, jejunum and ileum were extracted for assessment of cytokines, inflammatory cells and titanium content. The cytokines interleukin (IL)-1b, IL-4, IL-6, IL-8, IL-10, IL-12, IL-13, IL-17, IL-23, tumor necrosis factor-α (TNF-α), intracellular interferon-γ (IFN-γ) and transforming growth factor-β (TGF-β) were evaluated by enzyme-linked immunosorbent assay in segments of jejunum and ileum (mucosa and underlying muscular tissue). CD4 + and CD8 + T cells, natural killer cells, and dendritic cells were evaluated in duodenum, jejunum and ileum samples fixed in 10% formalin by immuno-histochemistry. The titanium content was determined by inductively coupled plasma atomic emission spectrometry. RESULTS: We found increased levels of T CD4 + cells (cells/mm 2 ) in duodenum:NP 1240 ± 139.4, MP 1070 ± 154.7 vs 458 ± 50.39 (P < 0.01); jejunum:NP 908.4 ± 130.3, MP 813.8 ± 103.8 vs 526.6 ± 61.43 (P < 0.05); and ileum:NP 818.60 ± 123.0, MP 640.1 ± 32.75 vs 466.9 ± 22.4 (P < 0.05). In comparison to the control group, the groups receiving TiO 2 showed a statistically significant increase in the levels of the inflammatory cytokines IL-12, IL-4, IL-23, TNF-α, IFN-γ and TGF-β. The cytokine production was more pronounced in the ileum (mean ± SE):IL-12: NP 33.98 ± 11.76, MP 74.11 ± 25.65 vs 19.06 ± 3.92 (P < 0.05); IL-4: NP 17.36 ± 9.96, MP 22.94 ± 7.47 vs 2.19 ± 0.65 (P < 0.05); IL-23: NP 157.20 ± 75.80, MP 134.50 ± 38.31 vs 22.34 ± 5.81 (P < 0.05); TNFα: NP 3.71 ± 1.33, MP 5.44 ± 1.67 vs 0.99± 019 (P < 0.05); IFNγ: NP 15.85 ± 9.99, MP 34.08 ± 11.44 vs 2.81 ±
