Effect of endometrial biopsy method on ribonucleic acid quality and gene expression analysis in patients with leiomyoma.

Objective: To compare ribonucleic acid (RNA) quantity and purity in tissue collected with different endometrial sampling methods to establish the optimal tool for use in endometrial gene expression studies. Design: Observational study. Setting: University hospital. Patients: Fourteen patients with submucosal leiomyomas. Interventions: Unguided biopsies were obtained using a low-pressure suction device before hysteroscopy from 14 patients with submucosal leiomyomas followed by guided biopsy with a resectoscope loop. Fifty-seven samples were collected: 25 obtained using a suction device and 32 with a loop. Main Outcome Measures: Total biopsy weight, RNA purity, and RNA yield for each collection method. After complementary deoxyribonucleic acid synthesis, HOXA10 expression was measured by quantitative polymerase chain reaction in the endometrium overlying and remote from the leiomyoma, as similar expression throughout the cavity was a prerequisite for the use of unguided biopsy method. Results: The median weight of the samples was significantly larger when obtained with the low-pressure suction device than with the resectoscope loop (153 vs. 20 mg). The RNA yield was similar (suction curette, 1,625 ng/mg; resectoscope loop, 1,779 ng/mg). The A260-to-A280 ratio was satisfactory for 94.7 % of the samples, with no difference between the groups. The endometrial expression of HOXA10 was similar in areas overlying the leiomyoma compared with that in remote endometrial sites (2-ΔCt = 0.0224 vs. 0.0225). Conclusions: Low-pressure endometrial suction devices provide tissue samples with acceptable RNA purity and quantity for gene expression studies. The expression of HOXA10 did not differ between endometrial sampling sites even in the presence of leiomyomas.

A 15-20-year follow-up of mental health, psychosocial functioning and quality of life in a single center sample of individuals with differences in sex development.

Background: The aim of the study was to present metal health, psychosocial functioning and quality of life (QoL) of children and adolescents with a difference in sex development (DSD) from their first visit in the newly established multidisciplinary team in 2002-2004 in Norway. A secondary aim was to explore mental health, psychosocial functioning and QoL in the same cohort patient's as for today and finally explore any childhood predictors for these outcomes in adulthood. Methods: The first part of the study took place in 2002-2004 in a mixed cohort of children and adolescents born with a DSD in 1982-2002, compared to a healthy comparison group. This part involved semi-structured interviews and self-reported and proxy-reported questionnaires. The second part of the study is a longitudinal study of the same participants 15-20 years later (2018-2020). Results: The participants at baseline of the study consisted of 33 patients; 24 assigned females (congenital adrenal hyperplasia, androgen insensitivity syndrome, gonadal dysgenesis and ovotesticular DSD) and nine assigned males; all with a hypospadias diagnosis. Significant differences were found for behavioral and emotional problems between groups, 46, XX females with significant higher total scores on YSR (49.43 + 24.17, p = .047); 46, XY females (21.00 + 12.04, p = .032); and higher internalizing problems scores (YSR) in 46, XX females (16.57 + 9.74), compared with the 46, XY females (5.60 + 5.32, p = .047). A positive association between QoL of the participants in adulthood and PedsQL' social function (r = .657, p = .020) and psychosocial function in childhood (r = .596, p = .041) was found. Conclusions: In summary, this study demonstrated that adolescents assigned females with DSD might have more psychiatric problems and a poorer degree of psychosocial functioning compared to a healthy comparison group. As we do find an association with these problems in adolescence and later adult QoL, it is of great importance to respond to these behaviors in early life.

Patients' and relatives' perspectives on best possible care in the context of developing a multidisciplinary center for endometriosis and adenomyosis: findings from a national survey.

BACKGROUND: Endometriosis and adenomyosis are common benign conditions compromising both physical and psychological health, with a negative impact on quality of life. This survey aimed to establish what the users' perspectives are on best possible care in the context of developing a multidisciplinary center for endometriosis and adenomyosis in Norway. METHODS: An electronic questionnaire was developed in collaboration between the Norwegian Patient's Endometriosis Society (NPES) and gynecologists with special interest in endometriosis and adenomyosis. The questionnaire was distributed digitally to the members of NPES in May 2021. RESULTS: 938 participants answered the questionnaire. Better patient information, long term therapeutic plans and integration of their partners into their care were the main concerns. Multidisciplinary care was a key issue for the majority, with (n = 775) 89% stating a need for a consultation with a psychologist, (n = 744) 86% at least one consultation with a nutritionist, (n = 733) 85% a physiotherapist, and (n = 676) 78% needing a sex therapist and (n = 935) 99,7% consider research and (n = 934) 99,8% consider quality assurance initiated by the endometriosis center to be important. The qualitative analysis of free text answers revealed a great need for updated and easily accessible information, meeting competent health care professionals and being taken seriously/listened to. CONCLUSIONS: This survey shows similar perceptions and a high level of agreement regarding their needs amongst people with endometriosis and/or adenomyosis. This survey supports recommendations by the experts that endometriosis/adenomyosis care should be centralized in specialized, multidisciplinary centers. The results of the present work will be valuable for the future planning and development of a multidisciplinary endometriosis center.

Shortened cervix in the subsequent pregnancy after embolization for postpartum cervical hemorrhage.

Introduction. Rupture of a branch of uterine artery during delivery often leads to a massive postpartum hemorrhage that can be successfully treated using uterine artery embolization. Case Report. A 33-year-old woman had a cesarean section at term followed by a secondary postpartum hemorrhage due to a ruptured cervicovaginal branch terminating in a large, partially thrombosed hematoma of the cervix. She was given selective uterine artery embolization, and she was discharged to home in stable condition on the third day after embolization. In the forthcoming pregnancy a shortened cervix was a risk of threatened premature delivery from 26 weeks of gestation onwards. Conclusion. Superselective unilateral embolization of a thrombosed hematoma in the cervix might prevent extensive iatrogenic trauma of the cervix, which allows preservation of reproductive function.

Assessment of periodic blood loss: interindividual and intraindividual variations of pictorial blood loss assessment chart registrations.

STUDY OBJECTIVE: To explore the interindividual and intraindividual variation of Pictorial Blood Loss Assessment Chart (PBAC) registrations of subjective perception of minimal, normal, and heavy menstrual bleeding in women using their usual sanitary protection. DESIGN: Retrospective study (Canadian Task Force classification II-3). SETTING: University tertiary hospital. PATIENTS: Women who had participated in 4 previously published prospective studies using PBAC as the outcome measure. INTERVENTIONS: Patients underwent hysteroscopic removal of polyps, laparoscopic occlusion of uterine vessels, or uterine artery embolization, and control subjects received no treatment. MEASUREMENTS AND MAIN RESULTS: PBAC scores, hemoglobin concentration, and subjective assessment of periodic blood loss were recorded in 429 women during 1049 menstrual cycles. The median PBAC values in groups of women who assessed their bleeding as light, normal, and heavy were 45.0, 116.0, and 254.5, respectively (p < .001). Sensitivity and specificity for specific PBAC cutoff points were calculated using a receiver operating characteristic curve. The maximum sensitivity for assessment of heavy periodic blood loss (78.5) was reached at a PBAC score of 160. The corresponding specificity was 75.8. At PBAC values below 130, 90% of the women reported normal blood loss, and 91% had hemoglobin values >12.0 g/dL. The reliability of repeated PBAC scores for individual measures was assessed via calculation of the intraclass correlation coefficient, which for repeated PBAC measurements was 0.86 (95% confidence interval, 0.80-0.90) for average measures. CONCLUSION: The interindividual variation was high, and the intraindividual variation was low. A low PBAC score may be used to define treatment end points for clinical use or in trials.

Volumetric ablation of uterine fibroids using Sonalleve high-intensity focused ultrasound in a 3 Tesla scanner--first clinical assessment.

INTRODUCTION: The purpose of this study was to evaluate the feasibility and safety of the Sonalleve high-intensity focused ultrasound (HIFU; Philips Healthcare, Vantaa, Finland) system in ablating uterine fibroids in a 3T magnet. MATERIAL AND METHODS: Seven women were included in this study. Treatment was performed according to the manufacturer's recommendation. Technical data describing the HIFU procedures were collected. On MR images at baseline, immediately and 30 days after ablation, we evaluated the volumes of the uterus, the dominant fibroid and the ablation zone. The Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire was used to assess potential clinical response. RESULTS: The procedure was technically feasible in all patients. The median number of sonications performed during each procedure was 20 (range 2-27) per patient, the maximum temperature in all sonication cells was about 68°C. The median procedure time was 156 minutes (range 95-164). The non-perfused volume after treatment ranged from 1 to 27 ml and was unchanged or decreased in all but one patient at 30 days follow-up. There were no major adverse events. DISCUSSION: In our 3T magnet the system was able to heat tissue and induce areas of non-enhancement within uterine fibroids without major complications. Clinical benefit remains to be proven.

Uterine artery embolization versus laparoscopic occlusion of uterine arteries for leiomyomas: long-term results of a randomized comparative trial.

PURPOSE: To compare long-term symptom recurrence and 6-month magnetic resonance (MR) imaging results after two different treatments for uterine leiomyomas. MATERIALS AND METHODS: Sixty-six women with uterine leiomyomas were randomized to undergo uterine artery embolization (UAE) or laparoscopic bilateral occlusion of uterine arteries. Contrast-enhanced MR imaging was performed before treatment and after 6 months. RESULTS: Fifty-eight patients received treatment. Median follow-up time was 48 months (range, 8-73 months). Clinical failure and symptom recurrence occurred in 14 patients after laparoscopy (48%) and in five after UAE (17%; P = .02, log-rank test). Hysterectomy was performed in two patients after UAE (7%) and in eight after laparoscopy (28%; P = .041). Six-month MR imaging results were available for 26 patients treated with UAE and 22 treated with laparoscopy. The mean uterine volume was reduced by 51% (range, 16%-86%) after UAE treatment, compared with 33% (range, 6%-77%) after laparoscopy (P = .001). Complete leiomyoma infarction was seen in all 26 patients in the UAE group and in only five patients in the laparoscopy group (P < .001). Eleven patients experienced symptom recurrence later than 6 months. Uterine volume reduction at 6 months was 24% in this group, compared with 48% in the 37 patients with no recurrence (P = .004). Incomplete infarction of leiomyomas was seen in eight of the 11 cases of recurrence (73%) versus nine of 37 cases without recurrence (24%; P = .009). CONCLUSIONS: Recurrence rate was significantly lower after UAE than after laparoscopic treatment. Larger volume reduction and more complete devascularization of leiomyomas were found after UAE treatment and among patients with no recurrence.

Treatment of uterine myomas with transvaginal uterine artery occlusion: possibilities and limitations.

The objective of this pilot study was to evaluate the feasibility of a transvaginal clamp prototype used for temporary uterine artery occlusion as a treatment for myomas. In particular, we aimed to evaluate technical aspects of successful occlusion with angiography and magnetic resonance imaging (MRI) and to evaluate possible ureter occlusion with pyelography. Ten premenopausal women aged 34 to 37 years with menorrhagia and myomas were treated with a temporary uterine artery occlusion for 6 hours. Five patients did not complete the clamping procedure because of unsuccessful clamping. While the clamp was in position, angiographic examination of the uterine arteries and pyelography were performed in 8 of the patients. The clamps occluded both uterine arteries in 4 patients and 1 side in another 2. Two procedures occluded the ureter unilaterally. MRI with contrast was done before, the day after, and 3 months after the procedure. Three of 5 patients who completed the clamp treatment had reduced or no contrast enhancement at MRI afterward. Clinical effects were obtained in 3 patients. Difficulties with application of the vaginal clamp were related to initial learning and size of the myomas. Our initial experience shows that the treatment is feasible in some patients with symptomatic myomas. However, improvement of the technique and equipment is needed. Care with regard to the ureters is required during further studies aimed at evaluating this approach.

Laparoscopic occlusion compared with embolization of uterine vessels: a randomized controlled trial.

OBJECTIVE: To compare clinical outcome 6 months after treatment with bilateral laparoscopic occlusion of the uterine artery versus uterine leiomyoma embolization. METHODS: Sixty-six premenopausal women with symptomatic uterine leiomyomata were randomized to treatment with either laparoscopic occlusion of uterine arteries or uterine leiomyoma embolization. The primary outcome was reduction of blood loss from pretreatment to 6 months postoperatively, measured by a Pictorial Bleeding Assessment Chart. Secondary outcomes included patients' own assessment of symptom reduction, postoperative pain assessed using visual analog scales, ketobemidone used postoperatively, complications, secondary interventions, and failures. RESULTS: Fifty-eight women were included; 6-month follow-up data were available for 28 participants in each group. The percentage reduction in Pictorial Bleeding Assessment Chart scores did not differ between the treatment groups (52% after uterine leiomyoma embolization and 53% after laparoscopy, P=.96). The study had 52% power to detect a 20% difference on the Pictorial Bleeding Assessment Chart. Fewer participants in the group treated with uterine leiomyoma embolization complained of heavy bleeding after 6 months (4% compared with 21%, P=.044). The postoperative use of ketobemidone was higher after uterine leiomyoma embolization (46 mg compared with 12 mg, P<.001). CONCLUSION: Both laparoscopic occlusion of uterine vessels and embolizaton of uterine leiomyoma improved clinical symptoms in the majority of patients. Participants with the laparoscopic procedure had less postoperative pain but heavier menstrual bleeding 6 months after treatment. A larger study and longer follow-up is necessary before a definite conclusion can be made regarding the most effective treatment.

Multiple myomas treated with a temporary, noninvasive, Doppler-directed, transvaginal uterine artery clamp.

A 43-year-old woman with menorrhagia, dysmenorrhea, and pelvic pain of several years' duration had a uterus enlarged by myomas to the size of a 16-week pregnancy. Her uterine arteries were noninvasively transvaginally identified and occluded for 6 hours with a clamp that was guided by audible Doppler ultrasound. Following removal of the clamp, blood flow in the uterine arteries returned immediately. Menorrhagia symptoms diminished. Three months following treatment, uterine volume decreased by 48.9%, and dominant myoma volume decreased by 77.2%.

Laparoscopic occlusion of uterine vessels for the treatment of symptomatic fibroids: Initial experience and comparison to uterine artery embolization.

OBJECTIVE: Our purpose was to evaluate the effects of laparoscopic occlusion of uterine vessels in treating symptomatic fibroids and compare with embolization of the uterine arteries. STUDY DESIGN: We studied 46 premenopausal women, aged 43 (34-51) years with symptomatic uterine fibroids, undergoing radiologic embolization (n=24) and laparoscopy closure of the uterine arteries (n=22). RESULTS: The laparoscopic technique reduced picture blood assessment score after 6 months by 50% from an initial value of 345 (+/-288). Uterus volume was reduced by 37% (+/-18%), and the dominant fibroid was reduced by 36% (+/-31%). Postoperative pain and use of pain relief differed significantly, requiring more pain medication after embolization: ketobemidon 38 mg compared with 16 mg in the laparoscopic group (P=.008). Specific complications to the laparoscopic technique were temporary damage to the obturator nerve in three patients. CONCLUSION: Laparoscopic occlusion of uterine vessels is a promising new method for treating fibroid-related symptoms, with less postoperative pain than embolization and comparable effects on symptoms.
