ABSTRACT

Introduction: Vaginal laxity, a symptom of pelvic floor dysfunction observed in women, has many negative biological and psychological impacts. Laser treatments and stem cell-based therapies are emerging therapeutic methods for treating this condition. This study aimed to determine changes in vaginal laxity in model rats using a combination therapy of erbium-doped yttrium aluminium garnet (Er:YAG) fractional lasers and topical treatment with amniotic membrane stem cell metabolite products (AMSC-MP). Methods: The experimental animal population comprised 36 female white rats (Rattus norvegicus; 2-day-post-vaginal-delivery rats) allocated into the following four groups (n=9): K1, untreated two-day-post-vaginal-delivery rats; K2, two-day-post-vaginal-delivery rats treated with topical gel without AMSC-MP; P1, two-day-post-vaginal-delivery rats treated with Er:YAG fractional lasers and topical gel without AMSC-MP; P2, two-day-post-vaginal-delivery rats treated with Er: YAG fractional lasers and topical gel containing AMSC-MP. Immunohistochemical (IHC) examination was carried out for the expression and activity of heat shock protein 70 (HSP-70), collagen-1, tissue inhibitors of metalloproteinase 1 (TIMP-1) and matrix metalloproteinase 1 (MMP-1), as well as vaginal mucosal thickness. Results: There was a significant difference (P<0.05) in the expression of HSP-70 among all groups except K2 and P1 (P>0.05); there was no significant difference in type I collagen and TIMP-1 expression between the groups (P>0.05); there was a significant difference (P<0.05) in MMP-1 activity, with the activity in the K2 group (5.79±0.83) being higher than that in the P1 group (4.44±1.82) and that in the K1 group (5.74±1.03) being higher than that in the P2 group (4.24±1.55). Also, there was a significant difference in the thickness of the vaginal mucosa in all groups except K2 and P1 (P>0.05). Conclusion: Er:YAG fractional laser and AMSC-MP combination therapy improved vaginal laxity in model rats by increasing Hsp70 expression and vaginal mucosal thickness and decreasing MMP-1 activity.

ABSTRACT

Objectives: Vaginal relaxation syndrome (VRS) comprises vaginal laxity and stress urinary incontinence (SUI). Laser vaginal tightening (LVT) therapy using a fractional erbium:yttrium aluminum garnet (Er:YAG) 2.940 nm laser may represent a nonsurgical option for both complaints. This study evaluates the effectiveness and side effects of fractional Er:YAG laser therapy in VRS patients. The improvement in VRS was evaluated. Materials and Methods: This is a retrospective study analyzing the medical records of patients treated with fractional Er:YAG laser therapy in our private clinic in Surabaya, Indonesia. Objective questions were asked to rate patients' satisfaction with the results of the therapy, namely dissatisfaction, and mild, moderate, or strong satisfaction. Statistical analysis used, data were input into tables in Microsoft Excel. Results: Twenty-four VRS patients (54% with vaginal laxity, 33% with SUI, and 13% with vaginal laxity and SUI) were studied. Most of the patients were 36-45-year-old and had 2 children, and 79% of the patients had had a vaginal delivery. After 3 LVTs, mild satisfaction was observed in 15% of patients, moderate satisfaction was noted in 54% of patients, and high satisfaction was noted in 31% of patients. Among 11 patients with SUI, 36% recovered after the first LVT, and 100% recovered after the second LVT therapy. One patient experienced mild fluor albus as a side effect. Conclusion: LVT therapy with a fractional Er:YAG laser was determined to be effective and safe as a treatment for VRS.

ABSTRACT

OBJECTIVE: The objective of this study was to discover the possible correlation between p16INK4A expression and the LR/HR-HPV infection in condyloma acuminate (CA) lesions. MATERIALS AND METHOD: This cross-sectional study was conducted during January-December 2017 on 33 CA patients. The expression of p16INK4A was detected by immunohistochemistry (IHC) staining. The positive interpretation was carried out by scoring which score 0 was negative, score 1 was sporadic, score 2 was focal, and score 3 was diffuses. The HPV genotypes were identified by reverse line blot, and 40 genotypes of HPV detected, including HR-HPV (HPVs 16, 18, 26, 31, 33,35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 67, 68a, 68b, 69, 73, and 82) and LR-HPV (HPVs 6, 11, 40, 42, 43, 44, 54, 55, 61, 62, 64, 70, 71, 72, 81, 83, 84, 87, 89, and 90). RESULTS: The expression of p16INK4A was significantly correlated with HR-HPV infection. Patients infected with HR-HPV had 0.644 times higher possibility to express p16INK4A gene compared to those infected with LR-HPV. LR-HPV genotypes detected in CA patients were HPVs 6, 11, 42, 61, 54, 81, 87, 89, and 90 and HR-HPV genotypes were HPVs 18, 26, 45, 51, 52, 67, 68B, 69, and 82. LR-HPV was found in 19/33 of patients and HR-HPV was in 14/33 of patients. The expression of p16INK4A in CA lesions was diffuse in15.2% of patients, was focal in 24.2% of patients , was sporadic in 39.4% of patients were, and was negative in 21.2% of patients . In LR-HPV group, there was no diffuse expression, focal expression was observed in 15.8%, sporadic in 47.4%, and negative in 36.8%, while in HR-HPV group, p16INK4A expression was detected in all lesions , in a way that its expression was diffuse in 35.7%, focal in 35.7%, and sporadic in 28.6%. CONCLUSION: IHC is a routine method in histopathological diagnosis, therefore the detection of p16INK4A expression by IHC can be used as a biomarker for HR-HPV infection diagnosis.
