Risk-Reducing Salpingo-Oophorectomy and the Use of Hormone Replacement Therapy Below the Age of Natural Menopause: Scientific Impact Paper No. 66 October 2021: Scientific Impact Paper No. 66.

This paper deals with the use of hormone replacement therapy (HRT) after the removal of fallopian tubes and ovaries to prevent ovarian cancer in premenopausal high risk women. Some women have an alteration in their genetic code, which makes them more likely to develop ovarian cancer. Two well-known genes which can carry an alteration are the BRCA1 and BRCA2 genes. Examples of other genes associated with an increased risk of ovarian cancer include RAD51C, RAD51D, BRIP1, PALB2 and Lynch syndrome genes. Women with a strong family history of ovarian cancer and/or breast cancer, may also be at increased risk of developing ovarian cancer. Women at increased risk can choose to have an operation to remove the fallopian tubes and ovaries, which is the most effective way to prevent ovarian cancer. This is done after a woman has completed her family. However, removal of ovaries causes early menopause and leads to hot flushes, sweats, mood changes and bone thinning. It can also cause memory problems and increases the risk of heart disease. It may reduce libido or impair sexual function. Guidance on how to care for women following preventative surgery who are experiencing early menopause is needed. HRT is usually advisable for women up to 51 years of age (average age of menopause for women in the UK) who are undergoing early menopause and have not had breast cancer, to minimise the health risks linked to early menopause. For women with a womb, HRT should include estrogen coupled with progestogen to protect against thickening of the lining of the womb (called endometrial hyperplasia). For women without a womb, only estrogen is given. Research suggests that, unlike in older women, HRT for women in early menopause does not increase breast cancer risk, including in those who are BRCA1 and BRCA2 carriers and have preventative surgery. For women with a history of receptor-negative breast cancer, the gynaecologist will liaise with an oncology doctor on a case-by-case basis to help to decide if HRT is safe to use. Women with a history of estrogen receptor-positive breast cancer are not normally offered HRT. A range of other therapies can be used if a woman is unable to take HRT. These include behavioural therapy and non-hormonal medicines. However, these are less effective than HRT. Regular exercise, healthy lifestyle and avoiding symptom triggers are also advised. Whether to undergo surgery to reduce risk or not and its timing can be a complex decision-making process. Women need to be carefully counselled on the pros and cons of both preventative surgery and HRT use so they can make informed decisions and choices.

Inositol treatment of anovulation in women with polycystic ovary syndrome: a meta-analysis of randomised trials.

Polycystic ovary syndrome is a common cause of anovulation and infertility, and a risk factor for development of metabolic syndrome and endometrial cancer. Systematic review and meta-analysis of randomised controlled trials (RCT) that evaluated the effects of inositol as an ovulation induction agent. We searched MEDLINE, EMBASE, Cochrane and ISI conference proceedings, Register and Meta-register for RCT and WHO trials' search portal. We included studies that compared inositol with placebo or other ovulation induction agents. Quality of studies was assessed for risk of bias. Results were pooled using random effects meta-analysis and findings were reported as relative risk or standardised mean differences. We included ten randomised trials. A total of 362 women were on inositol (257 on myo-inositol; 105 on di-chiro-inositol), 179 were on placebo and 60 were on metformin. Inositol was associated with significantly improved ovulation rate (RR 2.3; 95% CI 1.1-4.7; I2 = 75%) and increased frequency of menstrual cycles (RR 6.8; 95% CI 2.8-16.6; I2 = 0%) compared with placebo. One study reported on clinical pregnancy rate with inositol compared with placebo (RR 3.3; 95% CI 0.4-27.1), and one study compared with metformin (RR 1.5; 95% CI 0.7-3.1). No studies evaluated live birth and miscarriage rates. Inositol appears to regulate menstrual cycles, improve ovulation and induce metabolic changes in polycystic ovary syndrome; however, evidence is lacking for pregnancy, miscarriage or live birth. A further, well-designed multicentre trial to address this issue to provide robust evidence of benefit is warranted. TWEETABLE ABSTRACT: Inositols improve menstrual cycles, ovulation and metabolic changes in polycystic ovary syndrome.

The clinical efficacy of laser assisted modified Widman flap: A randomized split mouth clinical trial.

OBJECTIVE: The objective of the study was to compare the clinical efficacy of use of a diode laser (DL) (810 nm) as an adjunct to modified Widman flap (MWF) surgery to that of MWF alone. MATERIALS AND METHODS: Twenty-five patients between the ages of 20 and 50 years with generalized chronic periodontitis were selected for the study. Control sites (Group A) were randomly selected to receive an MWF, and the contralateral test sites (Group B) received MWF in conjunction with low-level laser therapy. The energy density of 4 J/cm² was applied to the gingival surface after periodontal treatment. The study tooth/site was treated along with any additional teeth in the quadrant in which the site was located if needed. Randomization was done using a coin flip. The DL was used to de-epithelialize the inner part of the periodontal flap and photo-biostimulate the surgical area. Plaque index (PI), papillary bleeding index (PBI), probing depth (PD), and clinical attachment level (CAL) scores were recorded at baseline and at 6 and 9 months. STATISTICAL ANALYSIS: Data were expressed as the mean ± standard deviation. Statistical analyzes were performed using paired Student's t-testfor intragroup comparisons and unpaired Student's t-test for intergroup comparisons. RESULTS: No significant difference was observed in PI scores between the two groups at baseline, 6 and 9 months. PBI scores were significantly lower in Group B versus Group A at 6 months (P < 0.01). However, no significant difference was observed between the two groups in PBI scores at the end of 9 months. PD reduction in Group B versus Group A was statistically significant at the end of 9 months (P < 0.01). Gains in CAL were significantly greater in Group B versus Group A at 6 and 9 months. CONCLUSION: The use of an 810 nm DL provided additional benefits to MWF surgery in terms of clinical parameters.

Reproductive outcome following abdominal myomectomy for a very large fibroid uterus.

The aim of this study was to assess the long-term reproductive outcome following abdominal myomectomy in women with very large fibroid uteri. It is a retrospective study of 90 subfertile women with the main outcome measure of live-birth rate following spontaneous and assisted conception. Mean age of the study population was 37 ± 5 years and mean uterine size was 21 ± 6 weeks. During follow-up (mean 50 ± 10 months), 28 (31%) pregnancies occurred; 18 spontaneous and 10 following IVF. The live-birth rate was 20% and the miscarriage rate was 32%. Multivariate analysis demonstrated that the chance of live birth was significantly reduced with increasing female age at the time of surgery (OR = 0.67, 95% CI 0.51-0.86, p = 0.002). The perioperative blood transfusion rate was 30% and the incidence of major complications was 6%. Fertility after abdominal myomectomy for very large fibroid uteri is possible, and its major determinant is female age at the time of surgery.

Role of tranexamic acid in endoscopic sinus surgery - a systematic review and meta-analysis.

BACKGROUND: The role of tranexamic acid in patients undergoing endoscopic sinus surgery (ESS) is not clearly defined. The aim of our study is to systematically review the existing evidence on the role of tranexamic acid in patients undergoing ESS. METHODOLOGY: Systematic search of MEDLINE (1950 - 2013), EMBASE (1980 - 2013), metaRegister, Cochrane Library and ISI conference proceedings was carried out. RESULTS: Five randomised controlled trials with 192 patients receiving tranexamic acid and 196 controls were included. Meta-analysis demonstrated that mean estimated blood loss was significantly lower, and surgical field quality was significantly better in tranexamic acid group. There was no significant difference in mean operative time between the two groups. No significant adverse effects were noted in either of the groups. CONCLUSION: Intra-operative use of local and systemic tranexamic acid in ESS, results in significantly reduced estimated blood loss and improved surgical field quality. There is no statistically significant difference seen in operative time and incidence of side effects. Well-conducted larger RCTs using validated objective outcome measures and reporting on minor and major complications are required.

Perioperative morbidity associated with abdominal myomectomy compared with total abdominal hysterectomy for uterine fibroids.

The aim of the study was to systematically review and summarise existing evidence related to the perioperative morbidity associated with abdominal myomectomy in comparison with abdominal hysterectomy for uterine fibroids. A review of MEDLINE and EMBASE was carried out. The primary outcome was the major morbidity rate and secondary outcomes were uterine size, estimated blood loss, blood transfusion, operating time and duration of hospital stay. The results identified six observational studies including 1520 participants. All studies scored moderately on the N-OQA scale and were limited to a uterine size of up to 18 weeks. There was no significant difference in the rate of major morbidity (RR 0.94; 95% CI = 0.31, 2.81; p = 0.91) between the two operations. It was concluded that based on variable quality data from retrospective cohort studies, abdominal myomectomy and hysterectomy appear to have similar major morbidity rates for the uterine size up to 16-18 weeks. Well-designed trials with a standardised morbidity outcome and including uterine size greater than 18 weeks are required.

Peri-operative morbidity associated with abdominal myomectomy for very large fibroid uteri.

OBJECTIVE: To evaluate the safety of abdominal myomectomy for very large fibroid uteri, and to assess the effect of relevant confounding variables on the occurrence of major peri-operative complications. STUDY DESIGN: A cohort study of 200 abdominal myomectomies for fibroid uteri of 16 gestational weeks or greater. Logistic regression analysis was used to examine the influence of important clinical variables on the risk of complications. A systematic literature search was conducted for evidence related to peri-operative morbidity associated with abdominal myomectomy for very large fibroid uteri. RESULTS: The mean (±standard deviation) uterine size was 21±5 weeks. The overall rate of major complications was 30%. Peri-operative bleeding necessitating blood transfusion occurred in 49 (24.5%) cases. During surgery, two patients had bowel injury, two had bladder injury, seven women returned to theatre and two (1%) had hysterectomy. Four patients were re-admitted within 14 days of surgery. Multivariable logistic regression analysis showed that the risk of major complications was significantly higher in cases with a uterine size of 20 gestational weeks or more [odds ratio (OR) 3.4, 95% confidence interval (CI) 1.1-10.2; p=0.03], where 10 or more fibroids were removed (OR 3.5, 95% CI 1.1-10.8; p=0.05) and where midline skin incision was required (OR 6.1, 95% CI 1.7-22.3; p=0.006). On comparison of primary vs repeat abdominal myomectomy, there was significantly higher blood loss (mean 1023±1112 ml vs 579±787 ml; p=0.02) and risk of major complications in the repeat myomectomy group (40% vs 5%; p<0.001). The systematic review identified only one study that reported a comparable risk of major complications related to abdominal myomectomy for very large fibroid uteri. CONCLUSION: The risk of organ injury, hysterectomy, re-operation or hospital re-admission after abdominal myomectomy for very large fibroid uteri is low, but the procedure is associated with a significant risk of bleeding necessitating blood transfusion. This risk is increased after repeat myomectomy, and in patients with a uterine size of 20 gestational weeks or larger, requiring removal of 10 or more fibroids, and requiring a midline skin incision.

A review of the management of diseases of the Bartholin's gland.

Bartholin's abscess and cyst account for 2% of all gynaecological visits per annum. This article reviews the anatomy, epidemiology and pathophysiology of the Bartholin's gland. The management of Bartholin's abscess including antibiotic use in the early stage of the condition together with options for surgical intervention are discussed and in so doing the variation of clinical practice in other countries is considered. The use of the word catheter, carbon dioxide laser are compared with traditional surgical techniques of incision and drainage and marsupialisation. The outcomes of treatment particularly the high recurrence rate (2-25%) and the associated morbidity are reviewed. Finally the issue of cancerous pathology as an aetiology is highlighted in the postmenopausal age group.
