RESUMEN

OBJECTIVE: To investigate the efficacy and adverse effects of focused ultrasound (FU) in the treatment of high-grade squamous intraepithelial lesions (HSIL) and follow up on pregnancy outcomes in patients. METHODS: This retrospective study recruited 57 patients aged 20-40 years with cervical HSIL combined with HR-HPV infection who received FU treatment between September 2019 and April 2022. Clinical data of the patients were obtained from hospital records. HSIL cure rate and cumulative HR-HPV clearance rate were assessed after treatment. Patients were followed up on fertility and pregnancy outcomes after treatment by telephone interviews until April 1, 2023. RESULTS: During a 6-month follow-up, the HSIL cure rate was 73.7%, and a statistical difference between CIN2 and CIN3 (75.6% vs. 66.7%, p = 0.713) was not present. HSIL -recurrence was not observed during the follow-up period, and the median follow-up duration was 12 months. The cumulative HR-HPV clearance rates at the 6- and 12-month follow-ups were 56.1% and 75.4%, respectively. The median clearance time of HR-HPV was 6 (95% confidence interval, 5.46-6.54) months. The clearance rate was higher in HPV16/18 than in non-HPV16/18 (86.7% vs. 62.9%, p = 0.038). After treatment, the successful pregnancy rate in patients with fertility intentions and spontaneous abortion rate were 73.9% and 5.9%, respectively. Preterm birth, preterm premature rupture of membranes, or low-birth-weight infants were not observed. CONCLUSION: FU treatment can regress HSIL and accelerate HR-HPV clearance in young women of childbearing age with cervical HSIL associated with HR-HPV infection, and has no significant adverse effects on pregnancy outcomes.

RESUMEN

BACKGROUND: Rumination, a transdiagnostic factor in different psychopathological conditions, is believed to be activated and sustained by dysfunctional metacognition. The Positive Beliefs about Rumination Scale (PBRS) and the Negative Beliefs about Rumination Scale (NBRS) have been used to measure the metacognitive beliefs of rumination and have been investigated in many cultural contexts. However, it remains unclear whether these scales can work as well for the Chinese population. Therefore, this study aimed to explore the psychometric properties of the Chinese versions of these scales and to test the metacognitive model of rumination for students with different levels of depression. METHODS: The PBRS and NBRS were forward-backward translated into Mandarin. In total 1,025 college students were recruited to complete a battery of web-based questionnaires. Exploratory factor analysis, confirmatory factor analysis, and correlation analysis were used to test the structure, validity, and reliability of the two scales, as well as their item correlations with rumination. RESULTS: A new two-factor structure of the PBRS (rather than the original one-factor model) and a new three-factor structure of the NBRS (rather than the original two-factor model) were extracted. The goodness-of-fit indices of these two factor models showed they had a good to very good fit with the data. The internal consistency and construct validity of PBRS and NBRS were also affirmed. CONCLUSION: The Chinese versions of the PBRS and the NBRS were generally shown to be reliable and valid, but their newly extracted structures fit the Chinese college students better than their original structures. These new models of PBRS and NBRS are of value to be further explored in Chinese population.

RESUMEN

OBJECTIVE: To evaluate the changes of cervical soluble immune markers after focused ultrasound (FU) treatment to explore the underlying local immune effects of FU in the treatment of high-risk human papillomavirus (HR-HPV) infection-related low-grade squamous intraepithelial lesion (LSIL). METHODS: A total of 35 patients diagnosed with HR-HPV infection-related histological LSIL who met the inclusion criteria were enrolled in this prospective study and treated with FU. The authors used cytometric bead array to measure T-helper type 1 (Th1) cytokine (interleukin [IL] 2, tumor necrosis factor, and interferon γ) and Th2 cytokine (IL-4, IL-5, IL-6, and IL-10) levels in the cervicovaginal lavage of patients before and 3 months after FU treatment. RESULTS: After FU treatment, the concentrations of Th2 cytokines IL-5 and IL-6 were significantly lower than those before FU treatment (P = 0.044 and P = 0.028, respectively). HR-HPV infection was cleared in 27 patients, with a clearance rate of 77.1% (27 of 35). The concentration of IL-4 in patients with HR-HPV clearance after FU treatment was significantly lower than that in patients without HR-HPV clearance (P = 0.045). CONCLUSION: FU can inhibit the production of certain Th2 cytokines and may improve the local immune status of the cervix, thereby eliminating HR-HPV infection.

RESUMEN

BACKGROUND: Due to resistance and intolerance to chemotherapy, localized lesion resection may be required in some patients with Gestational trophoblastic neoplasia (GTN), which may lead to massive bleeding. In this case report, we describe the successful use of high-intensity focused ultrasound (HIFU) as an effective pretreatment method for surgical procedure in a patient with GTN to reduce the perioperative risk and the impact on fertility. CASE PRESENTATION: A 26-year-old woman was diagnosed with high-risk GTN (FIGO Stage III: 12 prognostic scores) after a hydatidiform mole. The fifth chemotherapy cycle was interrupted due to severe chemotherapy toxicity. However, the uterine lesion was still present and the beta-human chorionic gonadotropin (ß-hCG) level was not restored to normal. Therefore, ultrasound-guided HIFU was performed as a pretreatment method to shrink the lesion and prevent massive bleeding during localized lesion resection. The effectiveness of ablation was evaluated immediately using contrast-enhanced ultrasound and Color Flow Doppler ultrasonography. One month after HIFU treatment, the uterine lesion was completely resected under hysteroscopic surgery. During the surgery, HIFU was found to have shrunk the lesion and there was minimal bleeding (5 mL). The uterine cavity morphology and menstruation returned to normal after surgery. The patient has showed no signs of recurrence as of one-year follow-up. CONCLUSION: Ultrasound-guided HIFU ablation may be a new choice for high-risk GTN patients with chemoresistance or chemo-intolerance. As a noninvasive pretreatment method, HIFU can shrink the uterine lesion, and reduce the risk of bleeding with no obvious effect on fertility.

RESUMEN

OBJECTIVE: To investigate the impact of ultrasound-guided high-intensity focused ultrasound (USgHIFU) on pregnancy in submucous leiomyomas. MATERIALS AND METHODS: Between October 2015 and October 2021, a retrospective observational study was conducted at the Affiliated Hospital of North Sichuan Medical College, China, for 32 women with submucous leiomyomas who became pregnant after USgHIFU. Pregnancy outcomes, submucous leiomyomas characteristics, and USgHIFU parameters were analyzed. RESULTS: A total of 17 (53.1%) deliveries were successfully achieved, with full-term delivery in 16 (94.1%) patients and preterm delivery in 1 (5.9%). After USgHIFU, the effective volume in the uterus cavity and the volume of submucous leiomyomas shrank in all 32 patients. The median time to achieve pregnancy after USgHIFU was 11.0 months. Before pregnancy, myoma type was downgraded in 13 (40.6%) patients, stable in 10 (31.3%) and upgraded in 9 (28.1%). The vaginal expulsion rate of submucous leiomyomas was 28.1%, with complete expulsion in 3 (9.4%) patients and partial expulsion in 6 (18.8%). After USgHIFU, the size of submucous leiomyomas did not increase in each trimester (all p > 0.05). The high complications rate during pregnancy (7/17, 41.2%) was associated with advanced maternal age, with only one (5.9%) premature rupture of membranes possibly associated with submucous leiomyomas. There were 6 (35.5%) vaginal delivery and 11 (64.7%) cesarean sections. All 17 newborns developed well, with a mean birth weight of 3482 g. CONCLUSIONS: In patients with submucous leiomyomas, pregnancies and full-term deliveries can be successfully achieved following USgHIFU, with few related complications.

RESUMEN

BACKGROUND: The reported recurrence rate of endometrial polyps (EPs) after hysteroscopic polypectomy varied widely, and the factors influencing the recurrence of EPs are still controversial. Furthermore, the known definite independent risk factors are almost unchangeable, such as the number of EPs and previous polypectomy history. The aim of this study was to evaluate the impact of chronic endometritis (CE) on the recurrence of EPs in premenopausal women who underwent hysteroscopic polypectomy. METHODS: A retrospective study was conducted at a university-affiliated hospital. Premenopausal women who underwent hysteroscopic polypectomy were enrolled, and those with definite confounding factors for polyp recurrence were excluded, including endometriosis and previous polypectomy history. A total of 233 women were enrolled in this study, including 64 (27.5%) cases with CE and 169 (72.5%) cases without CE. CE was diagnosed via immunohistochemical detection of CD138 on the endometrial specimen. Comparison of the recurrence rate of EPs was performed in women with or without CE at each monitoring stage (i.e., at 3, 6, 9 and 12 months) after hysteroscopic polypectomy. RESULTS: The recurrence rates of EPs at one year in patients with and without CE were 26.6% (95% confidence interval [CI] 15.8-37.4%) and 9.5% (95% CI 5.0-14.0%), respectively, with an overall recurrence rate of 14.2% (95% CI 9.7-18.7%). The hazard ratio (HR) for EPs recurrence in the EPs with CE cohort versus the EPs without CE cohort was 3.08 (95% CI 1.56-6.09) (P = 0.001). Similarly, the recurrence rate of EPs was significantly higher in women with CE than in those without CE at each monitoring stage (i.e., 3, 6 and 9 months). CE and multiple EPs were risk factors for EPs recurrence. The HR for EPs recurrence in the EPs with CE cohort compared with the EPs without CE cohort was 3.06, after adjustment for the number of EPs. CONCLUSIONS: CE was a harmful factor for the recurrence of EPs in premenopausal women after hysteroscopic polypectomy. Thus, routine screening for CE during hysteroscopic polypectomy was needed. Frequent monitoring was needed for multiple EPs as the number of EPs also contributed to polyp recurrence.

RESUMEN

BACKGROUND: In this study, the changes of vaginal microbiome after focused ultrasound (FU) treatment were evaluated to explore the possible mechanism of FU in the treatment of high-risk human papillomavirus (HR-HPV) infection. METHODS: This study was nested in the FU arm of a prospective cohort study. A total of 37 patients diagnosed with HR-HPV infection-related cervical low-grade squamous intraepithelial lesion (LSIL) who met the inclusion criteria were enrolled in this study from October 2020 to November 2021, and these patients were treated with FU. We used 16S ribosomal RNA (16S rRNA) gene amplicon sequencing to profile the vaginal microbiota composition of patients before and 3 months after FU treatment. RESULTS: After FU treatment, HR-HPV was cleared in 24 patients, with a clearance rate of 75.0% (24/32). Lactobacillus iners was the predominant species among all samples. No significant difference was found in alpha-diversity index before and 3 months after FU treatment (P > 0.05), but the rarefaction curves showed that the vaginal microbial diversity before FU treatment was higher than that after FU treatment. Linear discriminant analysis (LDA) effect size (LEfSe) showed that Bifidobacterium contributed the most to the difference between the two groups at the genus level, and the abundance after FU treatment was significantly higher than that before treatment (P = 0.000). CONCLUSIONS: The decrease of vaginal microbial diversity may be related to the clearance of HR-HPV infection, and FU treatment contributed to the decrease of vaginal microbial diversity. Increased Bifidobacterium abundance in the vaginal microbiome may be associated with clearance of HR-HPV infection, and FU treatment may contribute to the increase in Bifidobacterium abundance. TRIAL REGISTRATION NUMBER:  This study was registered in the Chinese Clinical Trial Registry on 23/11/2020 (ChiCTR2000040162).

RESUMEN

PURPOSE: To determine efficacy and safety of contrast-enhanced ultrasonography (CEUS) in high-intensity focused ultrasound (HIFU) ablation of uterine fibroids (UFs). METHODS: We retrospectively reviewed women undergoing HIFU ablation for UFs between June 2018 and January 2020. Before and after HIFU, patients underwent CEUS and magnetic resonance imaging (MRI) examinations. The relationship between CEUS features and ablation rate was analyzed. The time-intensity curves on CEUS were measured before and after HIFU ablation, and compared with those obtained using MRI. Adverse reactions were recorded. RESULTS: A total of 64 patients were included. The immediate HIFU ablation rate significantly differed between low-, iso-, and high-enhancement UFs (87.2% ± 1.6%, 83.3% ± 2.1%, and 72.9% ± 3.1%, respectively; p < 0.05). On CEUS, the peak time of the time-intensity curve was significantly longer after treatment than before treatment (32.2 ± 9.7 and 26.7 ± 9.4 s, respectively; p < 0.05). Peak intensity was significantly lower after treatment than before treatment (13.7 ± 7.5 and 30.9 ± 11.2 dB, respectively; p < 0.05). All measurements were comparable between CEUS and MRI. The most common peri- and post-procedure adverse reaction was pain, which was temporary. CONCLUSION: CEUS could dynamically and safely evaluate the immediate effects of the HIFU ablation of UFs.

RESUMEN

The aim of this study was to ascertain the safety of high-intensity focused ultrasound (HIFU) for high-grade cervical intraepithelial neoplasia grade 2/3 (CIN 2/3) in patients with fertility requirements. This was a prospective one-arm study. Consecutive CIN 2/3 patients diagnosed with histopathology were screened, enrolled and treated from September 2019 to September 2020 in the Affiliated Hospital of North Sichuan Medical College. All patients were treated with a combination of HIFU and antiviral treatment with REBACIN. The scheduled follow-up visits were 1 week, 1 mo, 3 mo, 6 mo and 12 mo after surgery. The primary outcomes included cure and human papillomavirus clearance rates. We screened 287 consecutive CIN 2/3 patients in our hospital, 29 of whom were enrolled and treated in this study. The cure rate reached 82.8% at 7 mo after treatment and 96.6% within 1 y. The HPV-negative rate reached 72.4% (21/29) around 6 mo after treatment, with mild side effects during and after the procedure. Our study suggests that in CIN 2/3 study participants with fertility requirements, HIFU + REBACIN therapy is a safe and effective therapeutic option with a high cure rate, HPV clearance and few side effects.

RESUMEN

BACKGROUND: The treatment of gestational trophoblastic neoplasia (GTN) is one of the success stories in medical oncology. GTN in the cesarean scar is a rare entity, but most cases need to be treated with hysterectomy or localized uterine lesion resection because of chemoresistant lesions and/or massive bleeding. We present a patient with post-molar GTN in the cesarean scar who was non-invasively treated with ultrasound-guided high intensity focused ultrasound (HIFU) to preserve the uterus and fertility. CASE PRESENTATION: A 32-year-old woman was diagnosed with low-risk GTN (FIGO Stage I: 2 prognostic score) after partial hydatidiform mole. The 5th cycle of chemotherapy was interrupted because of persistent hepatic toxicity and impaired ovarian reserve function. However, the uterine lesion persisted (diameter of residual uterine lesion in the cesarean scar: 2.0 cm). Therefore, ultrasound-guided HIFU treatment was performed. A significant gray-scale change was observed during the HIFU treatment. Color Doppler ultrasonography and contrast-enhanced ultrasound (CEUS) was performed to evaluate the ablation effectiveness. Color Doppler ultrasonography showed disappearance of the signal of vascularity and CEUS showed no perfusion in the lesion located in the cesarean scar. The uterine lesion was obviously shrunken one month after HIFU treatment. Menstrual cycle resumed 48 days after HIFU. HIFU treatment decreased the number of chemotherapy cycles and there was complete disappearance of the GTN lesion at 4-month follow-up. The patient has shown no signs of recurrence as of 58-month follow-up. CONCLUSION: Ultrasound-guided HIFU may be a useful alternative to lesion resection for GTN in the cesarean scar in patients who show chemoresistance or are not suitable for chemotherapy. It has the potential to ablate the residual uterine lesion noninvasively to preserve the uterus and fertility, avoiding perioperative risks of lesion resection, especially acute bleeding.

RESUMEN

BACKGROUND: To assess the efficacy of dysdrogesterone in the treatment of chronic endometritis (CE) treated with antibiotic in premenopausal women with endometrial polyps (EPs). METHODS: Routine detection of endometrium was simultaneously conducted to determine whether there was CE by syndecan-1 (CD138), while women underwent hysteroscopic polypectomy in our hospital. Antibiotic was given for the treatment of CE. A total of 235 premenopausal women with CE who underwent hysteroscopic polypectomy were enrolled in the retrospective observational study. In the control group, single antibiotic was given for the treatment of CE form January 2016 to December 2018, and in the treatment group additional dydrogesterone was used from January 2019 to November 2020. Comparison of cure rates of CE with different treatment regimens was performed. RESULTS: The cure rates of CE in dydrogesterone and antibiotic combination group and the single antibiotic group were 85.2% and 74.3%, respectively, with overall cure rate of 80.0% (188/235). The combination group showed better effects regarding the cure rate of CE (P < .05). Multivariate analysis confirmed that the cure rate of CE was not affected by age, body mass index, number of EPs, the status of estrogen receptor and the status of progesterone receptor. Conversely, dydrogesterone and endometrial scratching were beneficial factors for cure rate increase with antibiotic treatment. CONCLUSION: Combination of dydrogesterone and antibiotic was more effective for cure rate of CE than antibiotic alone in premenopausal women after hysteroscopic polypectomy. Endometrial scratching also contributed to the cure rate increase with antibiotic treatment.

RESUMEN

OBJECTIVES: To assess the efficacy and safety of focused ultrasound (FU) for high-risk human papillomavirus (HR-HPV) infection-related cervical low-grade squamous intraepithelial lesions (LSIL). METHODS: Of 185 patients who met the inclusion criteria for this prospective study from October 2020 to November 2021, 95 received FU and 90 were followed up only. At the six-month follow-up, the HR-HPV clearance and LSIL regression rates of the groups were compared and factors affecting HR-HPV clearance were analyzed. The safety and side effects of FU were evaluated. RESULTS: No significant difference was found in the baseline clinical data between the two groups (p > 0.05). At the six-month follow-up, the HR-HPV clearance rates were 75.6% in the FU group and 25.6% in the observation group (p = 0.000). The LSIL regression rates were 89.5% in the FU group and 56.4% in the observation group (p = 0.000). Multivariate logistic regression analysis showed that the HR-HPV clearance rate in the FU group was 9.03 times higher than that in the observation group (95% confidence interval [CI], 3.75-21.73, p = 0.000), and the clearance rate of single-type HR-HPV infections was 5.28 times higher than that of multi-type infections (95% CI, 1.83-15.23, p = 0.002). The mean intraoperative bleeding was 1.8 ± 0.6 (1-3) mL; the mean intraoperative pain score was 2.6 ± 1.0 (1-6). CONCLUSIONS: For patients with HR-HPV infection-related histological LSIL, FU can eliminate HR-HPV infection and cause lesions to regress in a short time, with few adverse effects and good tolerance.

RESUMEN

We herein report an unprecedented pathway to access γ-lactams using acetonitrile analogues as coupling partners without oxidants, ligands, and Lewis acids. The reaction undergoes Rh-catalyzed C(sp2)-H addition to carbon-bound nitriles with the aid of an amide traceless auxiliary followed by an annulation sequence, featuring a broad substrate scope, good functional group tolerance, and excellent chemo/stereoselectivity. Scale-up reactions and late-stage derivatizations highlight the potential synthetic utility of this methodology. A plausible mechanism is proposed based on mechanistic investigations.

RESUMEN

RESEARCH QUESTION: What are the pregnancy outcomes of IVF vitrified-warmed embryo transfer (IVF-FET) carried out in a clinical setting located at an altitude of 3650 m in Tibet, China? DESIGN: A retrospective analysis of 238 infertility couples (n = 344 treatment cycles) who underwent FET treatment at the Xizang Fukang Hospital, Tibet. The overall clinical pregnancy rate, implantation rate, live birth rate, miscarriage rate and ectopic pregnancy rate were statistically analysed. Women were categorized into two groups based on age: 35 years or younger (n = 265 cycles) and over 35 years (n = 79 cycles). The general characteristics and pregnancy outcomes were compared between the two groups. RESULTS: The clinical pregnancy rate, implantation rate, live birth rate, miscarriage rate, and ectopic pregnancy rate of the 344 FET cycles were 43.02%, 30.90%, 35.17%, 18.24% and 1.35%, respectively. The clinical pregnancy rate (46.04% versus 32.91%), implantation rate (33.92% versus 21.01%) and live birth rate (38.11% versus 25.32%) in the group aged 35 years or younger were significantly greater than those in the group aged over 35 years (P = 0.039, P = 0.004, P = 0.037). The miscarriage rate (17.21% versus 23.08%) and ectopic pregnancy rate (0.82% versus 3.85%) were not significantly different in the two groups. CONCLUSION: A live birth rate of 35.17% can be achieved with IVF-FET in high-altitude areas (3650 m above sea level). Maternal age is still an important determinant of clinical pregnancy rate, implantation rate, and live birth rate of infertile patients in high-altitude areas.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: Although several clinical trials have compared the clinical efficacy of clomiphene citrate (CC) combined with metformin (MET) in the treatment of women with polycystic ovary syndrome (PCOS), the results are controversial. Therefore, this study was designed to conduct a pooled analysis to evaluate the efficacy of CC combined with MET versus CC in these patients. METHODS: Computerized searches of the PubMed, Web of Science, Embase and Cochrane Library databases were conducted to identify eligible randomized controlled trials (RCTs) from the data obtained up to June 2021. The Cochrane Collaboration risk of bias tool was used to assess the risk of bias in individual RCTs, and RevMan 5.4 was used for data statistical analysis. RESULTS AND DISCUSSION: A total of 13 RCTs were included in the meta-analysis. These studies involved 1,353 patients, 707 of these were in the combination group and 646 in the monotherapy group. The results indicated a higher clinical pregnancy rate (risk ratio [RR] 1.28, 95% confidence interval [CI] 1.06-1.54, p = 0.01) in the combined group compared to the monotherapy group. However, no significant differences were observed in the ovulation rate (RR 1.13, 95% CI 0.98-1.30, p = 0.10), live birth rate (RR 1.13, 95% CI 0.89-1.42, p = 0.32), multiple pregnancy rate (RR 0.58, 95% CI 0.19-1.73, p = 0.33) and abortion rate (RR 1.26, 95% CI 0.86-1.84, p = 0.23) between the two groups. WHAT IS NEW AND CONCLUSION: CC combined with MET has an advantage in improving the clinical pregnancy rate compared to CC alone; however, there is no significant difference in the rate of ovulation. For better management of PCOS, a high-quality RCT is needed to demonstrate the safety of the combination.

RESUMEN

ABSTRACT: A detailed understanding of the diagnosis and treatment of uterine sarcoma in the real world is required due to its low incidence, high malignancy, lack of specific symptoms, and lack of high-level evidence supporting its clinical diagnosis and treatment. This study aimed to provide a basis for the standardized diagnosis and treatment of uterine sarcoma. It retrospectively analyzed the real-world data on the diagnosis, treatment, and prognosis of uterine sarcoma in western China.The clinical and pathological data of patients with uterine sarcoma diagnosed and treated between January 2009 and January 2019 in 13 medical centers from 4 western provinces of China, Sichuan, Guangxi, Shaanxi, and Xinjiang, were collected and further examined by univariate and multivariate analyses to find possible risk factors affecting the prognosis of uterine sarcoma.A total of 299 patients with various pathological types of uterine sarcoma were included, with an average age of 47.7 ±â€Š11.1 years. The univariate and multivariate analyses showed that age (P = .0081), family history (P = .0358), and chemotherapy regimen (P = .0005) significantly correlated with progression-free survival; while age (P = .0393) and International Federation of Gynecology and Obstetrics staging (P = .0141) significantly correlated with overall survival.As age increased, the risk of death in patients with uterine sarcoma increased; The disease tended to progress faster in lower-age patients. A family history of tumors had an impact on disease progression; however, the way in which it affected needs further exploration. Different chemotherapy regimens affected the patient's disease progression. This study suggested that the anthracycline chemotherapy regimen was slightly better.

RESUMEN

BACKGROUND: Ovarian pregnancy after assisted reproductive technology treatment has rarely been reported; ovarian pregnancy following intrauterine insemination (IUI) is even rarer, and only nine cases have previously been reported. CASE SUMMARY: We report a case of ovarian pregnancy rupture after ovulation induction and IUI. The patient presented with bilateral lower abdominal pain and was referred to the emergency department. Ultrasound examination revealed ovarian pregnancy and intraperitoneal bleeding. Laparoscopy revealed an ovarian pregnancy with hemoperitoneum, which was subsequently removed. Pelvic adhesions were detected intraoperatively, which were treated immediately. The patient spontaneously conceived an intrauterine pregnancy 3 mo later, which was ongoing at the time of writing this study. CONCLUSION: Close attention should be paid to any history of pelvic inflammatory disease before commencing IUI treatment,and patients with such a history should be closely followed up after IUI. Early measurement of serum ß-human chorionic gonadotropin levels and ultrasonic examination are essential for timely diagnosis of ovarian pregnancy after ovulation induction and IUI to avoid more serious complications.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate changes in anti-Müllerian hormone (AMH) levels after ultrasound-guided high-intensity focused ultrasound (USgHIFU) treatment of cesarean scar pregnancy (CSP). METHODS: A retrospective case series study was conducted in the Affiliated Hospital of North Sichuan Medical College. Thirty-two women with cesarean scar pregnancy who met the inclusion criteria were enrolled in the study between January 2018 and December 2019. All patients underwent USgHIFU treatment with or without suction curettage. Intraoperative blood loss in suction curettage and hysteroscopy procedures, time to return of ß-human chorionic gonadotropin (ß-hCG) to normal levels, and time to recovery of normal menstruation were recorded. AMH levels before and 3 months after HIFU treatment were compared to determine whether USgHIFU treatment affected ovarian reserve. RESULTS: AMH levels before and 3 months after HIFU ablation were 1.87 ± 1.19 ng/ml and 1.90 ± 1.17 ng/ml, respectively. There was no significant difference in AMH levels between the two-time points (p > .05). The median volume of intraoperative blood loss was 20 ml, the median time for the serum ß-hCG level to return to normal was 35.5 days, and the median time of menstruation recovery was 39 days. CONCLUSIONS: USgHIFU treatment for CSP was effective and safe without affecting ovarian reserve.

RESUMEN

OBJECTIVE: The purpose of this study was to compare the efficacy of focused ultrasound (FU) and interferon drug therapy for cervical intraepithelial neoplasia 1 (CIN1) and chronic cervicitis associated with high risk human papillomavirus (HR-HPV) infection, as well as analyze the influencing factors. METHODS: A retrospective cohort study was performed from January 2017 to December 2019. A total of 592 patients were enrolled, of which 300 patients were treated with FU and 292 patients were treated with interferon drugs. Kaplan-Meier curves and a COX regression model were used to compare the curative effects of the two therapeutic methods using HR-HPV clearance as the main outcome. The relationship between age, HR-HPV infection type, pathological type, preoperative HR-HPV status and HR-HPV clearance were also analyzed. RESULTS: The median time for HR-HPV clearance was 6.00 months (95% CI: 5.24-6.76) in the FU group and 26.00 months (95% CI: 22.32-29.68) in the medication group. A significant difference was observed between the two groups (χ2 =198.902, p = 0.000). The HR-HPV clearance rate was 4.927 (95% CI 3.840-6.321; p = 0.000) times higher in the patients treated with FU than those treated with interferon drugs. In the FU group, no significant difference was observed in HR-HPV clearance rate between CIN1 and chronic cervicitis (χ2=0.660, p = 0.416), which was also insignificant between HR-HPV persistent and non-persistent infections (χ2=0.751, p = 0.386). CONCLUSION: FU therapy can eliminate HR-HPV infections in a short period of time. Moreover, the treatment efficacy of FU was significantly superior to that of interferon drugs.

RESUMEN

To evaluate the impact of dydrogesterone in the treatment of chronic endometritis with antibiotic treatment in premenopausal women. A total of 188 chronic endometritis patients diagnosed by syndecan-1 (CD138) expression were enrolled in this randomized controlled trial study. Dydrogesterone and doxycycline were given in the treatment group, while single antibiotic was given in the control group. CD138, estrogen receptor, and progesterone receptor expression in samples of the endometrium was analyzed by immunohistochemistry. Comparison of chronic endometritis cure rate between groups was performed based on conversion of CD138 expression from positive to negative. The 188 cases included in the statistical analysis consisted of 93 cases in the treatment group and 95 cases in the control group. The cure rates of chronic endometritis in the dydrogesterone and antibiotic combination group and the single antibiotic group were 86.0% (80/93) and 72.6% (69/95), respectively, with an overall cure rate of 79.3% (149/188). The dydrogesterone and antibiotic combination group showed better effects regarding the cure rate of chronic endometritis (P<.05). Multivariate analysis showed that the cure rate of chronic endometritis was not affected by age, clinical diagnosis, hysteroscopic resection, estrogen receptor status, or progesterone receptor status (all P>.05). Addition of dydrogesterone was effective for the treatment of chronic endometritis with antibiotic treatment in premenopausal women. The study was retrospectively registered to Chinese Clinical Trial Registry (ChiCTR2000040227) in November 2020.
