RESUMO
Background Salpingectomy is a common surgical procedure in gynecology performed for various indications. Given its proximity to the ovaries and shared vascular supply, concerns have arisen regarding compromised ovarian reserve post-salpingectomy. Objective We aim to study the effect of two different energy sources (group 1: salpingectomy using bipolar electrocautery followed by division with scissors versus group 2: salpingectomy with ultrasonic shears) on residual ovarian reserve. The effect on ovarian reserve was assessed using serum levels of follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH), antral follicle count (AFC), and ovarian size pre- and postoperatively. Materials and methods According to the inclusion criteria, 68 women were included in the study and randomized into the bipolar electrocautery group and the ultrasonic shear group. The final analysis included 34 women in the bipolar electrocautery group and 32 in the ultrasonic shear group. Preoperatively, the ovarian reserve of all women was assessed using FSH, AMH, AFC, and ovarian size. These parameters were then reassessed at three months postoperatively, and the percentage change was analyzed. Results The mean baseline serum AMH and serum FSH values in the bipolar electrocautery group were 3.9 ± 2.9 ng/ml and 6.6 ± 2.1 IU/L, respectively, comparable with the values in the ultrasonic shear group, where serum AMH was 3.2 ± 2.9 ng/ml and serum FSH was 7.3 ± 3.9 IU/L. AFC and ovarian size were comparable between the two groups preoperatively (bipolar electrocautery group AFC was 8 ± 2.2, ovarian size on the right side was 3.3 ± 0.7 cm and on the left was 3.2 ± 0.6 cm; ultrasonic shear group AFC was 5.7 ± 2.3, ovarian size on the right side was 3.4 ± 0.8 cm and on the left was 3.2 ± 0.8 cm). After three months of postoperative analysis, AFC showed a significant fall from the preoperative value in the bipolar electrocautery group compared to the ultrasonic shear group (AFC reduced from 8 ± 2.2 to 5.5 ± 2.3 vs. 8.6 ± 0.5 to 7.9 ± 2.3; p=0.002). The other parameters showed no statistically significant change. Conclusion Our study suggests that ultrasonic shear is safer than bipolar electrocautery for preserving ovarian reserve after salpingectomy. However, further research is needed to confirm these findings.
RESUMO
Background During the peak of the Omicron wave, elective laparoscopic surgeries were restricted; however, semi-emergency and emergency cases were managed despite the limited resources and manpower. We conducted this study to assess the types of gynaecological laparoscopic surgeries performed, the difficulties faced during the Omicron wave, and how we could implement the lessons learnt from the previous Delta wave for better management of gynaecological cases in the Omicron wave. Methodology We conducted a prospective cohort study over a period of three months involving 105 patients who underwent laparoscopic surgeries. Based on the decision regarding surgical incision time, the surgeries were sub-classified into immediate, urgent, and expedited. The surgical outcome and satisfaction rates among the patients were assessed through various parameters. Results Most of the women (81.9%) were pre-menopausal. Diabetes and chronic hypertension were the predominant medical co-morbidities. Three patients had a history of cardiac valve replacement which required switching warfarin to unfractionated heparin in the pre-operative period. Nearly three-fourthsof the study patients were doubly vaccinated against coronavirus disease 2019 (COVID-19) (77; 73.4%). A total of 14 (13.3%) patients had a history of COVID-19 infection in the past two weeks prior to the current admission. Immediate, urgent, and expedited surgeries comprised 11.4%, 22.8%, and 65.8% of total surgeries, respectively. On assessing the ease of pre-operative preparation according to the five-point Likert scale, immediate, urgent, and expedited surgeries were rated with a mean score of two, four, and five, respectively. The mean duration of surgery in the immediate and urgent groups was 37.6 and 44.2 minutes, respectively. The expedited group comprising mostly laparoscopic myomectomies and hysterectomies required an average duration of 92.6 minutes. The mean rating of patient satisfaction measured by the Likert scale was four, five, and five, respectively, in the three subgroups. Pre-operative patient preparation during the Omicron wave was faster, thereby decreasing the decision to incision interval compared to the Delta wave. Conclusions The lessons learnt from the previous Delta wave were used to modify the existing hospital policies in the Omicron wave. More number of vaccinated ground staff, less stringent intubation and extubation protocols during surgery, and lesser duration of post-operative stay helped modify our existing hospital policies for better patient care and satisfaction.
RESUMO
Background: Stress urinary incontinence (SUI) is a common ailment in affecting quality of life. This study was performed to see role of incontinence severity index (ISI) in evaluating severity of SUI and to see the impact of treatment of SUI. Materials and Methods: A total of 40 women with the diagnosis of SUI on history and clinical examination were enrolled. ISI was calculated on all the women before treatment. All women were treated with either conservative treatment (pelvic floor exercises, life style modification, and duloxetine therapy) (4, 10%) or Burch's colposuspension (18, 45%) or tension-free obturator tape (18, 45%) as per clinical situation after discussion with patients. ISI was again calculated 6 months after treatment. Results: Mean age, parity, body mass index in the study were 41.60 years, 2.73, and 24.2 kg/m2, respectively. All 40 (100%) patients had SUI with the mean duration of symptoms being 4.04 years. A total of 11 (27.5%) had moderate SUI (ISI 3-6), while 24 (60%) had severe SUI (ISI 8-9), while 5 (12.5%) had very severe SUI (ISI 12). Range of pretreatment ISI was 3-12 with mean being 8.8 ± 3.2. Posttreatment ISI reduced significantly with range of 1-4 and mean of 1.3 ± 0.4 (P < 0.001). The reduction was significant for all the groups, but there was no significant difference in efficacy of three treatment groups. Statistical analysis was done using SPSS IBM Version 2-1-0 using Chi-square test, Fisher's Extract test, and ANOVA test as appropriate. Conclusion: ISI is a useful modality to evaluate the severity of SUI and to see the impact of treatment modalities on SUI.
RESUMO
Copper T 380-A (CuT380A) intrauterine device (IUD) has been an effective method of emergency contraception (EC). Levonorgestrel intrauterine system (LNG-IUS) has not been approved by the Food and Drug Association for EC till now. There are few studies that provide data regarding the efficacy of LNG-IUS as EC. This systematic review tried to explore the efficacy of LNG-IUS in preventing accidental pregnancies up to five days of unprotected intercourse. A systematic review of the published studies on the use of LNG-IUS as EC was done. All randomized trials, prospective cohorts, retrospective cohorts. and case-control study designs pertaining to this topic were included in this review. Abstracts were retrieved and reviewed by two authors independently. Variables pertaining to socio-demographic parameters, EC use-related variables (reason for use, frequency, time elapsed since coitus), and those associated with sexual habits were selected and recorded. A total of six articles were rendered for the review. High school students and those attending college accounted for 36.8%-51.8% of the study population. Data on the reason for seeking EC showed noncompliance to routine contraception as the most common reason, followed by failure of withdrawal method, breach of barrier contraception, and unplanned intercourse. With a negligible failure rate, LNG-IUS seemed to be a good alternative to the existing copper EC. Considering the plethora of noncontraceptive benefits associated, LNG-IUS can be safely provided as an option of EC in the cafeteria approach within five days of unprotected intercourse.
RESUMO
BACKGROUND: Posthysterectomy vault prolapse is a common problem after vaginal or abdominal hysterectomy. The objective was to assess the role of Pelvic Floor Distress Inventory 20 (PFDI-20) in evaluation of vault prolapse. MATERIALS AND METHODS: Prospective study in 20 women with posthysterectomy vault prolapse of Stage 2 and above. The outcome measure was to calculate PFDI-20 score in all cases before surgical intervention and to recalculate it again in 6 months after different surgical procedures for vault prolapse and to statistically compare the PFDI-20 score in different types of surgery over 4 years period at a tertiary referral hospital for surgical treatment. Prolapse was classified using Pelvic Organ Prolapse Quantification and intraoperative findings. All women were operated for vault prolapse as per hospital protocol and stage of prolapse by either vaginal sacrospinous fixation or abdominal sacrocolpopexy. RESULTS: Mean age, parity, and body mass index were 54.8 years, 3.5, and 22.71 kg/m2 respectively. Preceding surgery was vaginal hysterectomy in 75% women and abdominal hysterectomy in 25% women. Complaints were bulge or mass feeling at perineum (100%), pressure in lower abdomen and perineum (55%), and constipation (60%). The type of prolapse was vault prolapse (100%), cystocele (100%), rectocele (100%), and enterocele (45%). The range of PFDI-20 was 88-152 with mean being 123.50 ± 22.71 before surgery while its range decreased significantly to 80-126 with mean being 106.40 ± 16.45 after surgery (P < 0.01). Mean postoperative PFDI-20 score was 107.40 in vaginal sacrospinous fixation group and was 105.30 in abdominal sacrocolpopexy group and was not statistically different (P = 0.18). CONCLUSION: PFDI-20 score can be used to see the adverse impact of vault prolapse on pelvic floor and to assess the beneficial effect of different types of surgeries on the score.
RESUMO
Objective Pregnancy with an autoimmune disorder is faced with several risks for mother and fetus. The aim of the present study is to analyze the course and outcome of pregnancy in women with autoimmune disorders (AIDs). Methods A retrospective cohort study was conducted at a tertiary care teaching hospital. The hospital records of 153 pregnancies with autoimmune disorders and 1095 low-risk pregnant women who served as controls were reviewed. An adverse perinatal outcome was defined as the presence of any obstetric complications, including preeclampsia, eclampsia, abruption, antepartum hemorrhage (APH), prematurity, fetal growth restriction (FGR), intrauterine death (IUD), intrapartum event, mode of delivery, birth weight, neonatal intensive care unit (NICU) stay, or disease-specific neonatal complications. For all statistical tests with two-tailed probability, p<0.05 was considered statistically significant. Results A high incidence of adverse perinatal outcomes was observed in all women with AIDs when compared with age-matched controls. The highest incidence of adverse perinatal outcomes was observed in women with Takayasu's arteritis. The incidence of abortions was more in women with antiphospholipid antibody syndrome (APS) and Grave's disease (22.2% and 33.3%, respectively). The incidence of prematurity, fetal growth restriction (FGR), and low birth weight were highest in women with systemic lupus erythematosus (SLE). Pregnancy with myasthenia gravis and rheumatoid arthritis did not have any significant adverse impact on pregnancy outcomes. Conclusion We found a strong association between autoimmune disorders and obstetric complications. The multidisciplinary team approach and pre-pregnancy optimization of the disease improve maternal and fetal outcomes.
RESUMO
OBJECTIVE: To assess the levels of vitamin D in patients with Stress Urinary Incontinence (SUI) in gynecology clinic of All India Institute of Medical Sciences, New Delhi. MATERIALS AND METHODS: This is a cross sectional study on a total of 40 women presenting to gynecology outpatient department with stress urinary incontinence diagnosed by history and examination. The women were divided with moderate, severe and very severe SUI confirmed by incontinence severity index (ISI) and pad test. Vitamin D (serum 25 OH D) levels were measured in all cases by electrochemiluminenscene Immunoassay (ECLIA) using Roche Elecsys 2010 and levels of =30 ng/ml were taken as sufficient while levels between 20-30 ng/ml as insufficient and <20 ng/ml as deficient. Statistical analysis was performed using ANOVA test with P value of <0.05 taken as significant. RESULTS: Mean age of patients was 41.6 years. Mean parity was 2.73 and mean duration of symptoms was 4.14 years. Vitamin D levels ranged between 6-38 ng/ml with mean being 17.15±8.1 ng/ml. Levels were deficient (<20 ng/ml) in 30 (75%) women, insufficient (20-30ng/ml) in 7 (17.5%) women and sufficient (>30ng/ml) in 3 (7.57%) women. There was no significant correlation between severely of SUI and levels of vitamin D with Vit D being 19.18±5.76 ng/ml in moderate SUI, 16.96±9.03 ng/ml in severe SUI and 13.60 ± 2.09 ng/ml in very severe SUI. CONCLUSION: There was very high prevalence of vitamin D deficiency in SUI patients with 75% patients showing deficient levels and 17.5% showing insufficient levels in SUI patients. There is need to provide vitamin D supplementation in such women.
RESUMO
AIM: To evaluate the effect of antitubercular therapy (ATT) on an ovarian function such as ovarian reserve, ovarian dimensions, and ovarian stromal blood flow. SETTINGS AND DESIGN: Prospective study design. MATERIALS AND METHODS: Fifty infertile women with female genital tuberculosis (FGTB) without tubo-ovarian masses diagnosed by positive acid-fast bacilli culture or epithelioid granuloma on endometrial aspirate or positive polymerase chain reaction with positive findings on laparoscopy or hysteroscopy were recruited. The ovarian function tests were performed on day 2/3 as follicle-stimulating hormone (FSH) levels and anti-Mullerian hormone (AMH) levels. Ovarian dimensions (length, width, and depth) were measured using a transvaginal ultrasound. Mean antral follicle count (AFC) and ovarian stromal blood flow (peak systolic velocity [PSV], pulsatility index (PI), and resistive index [RI]) were measured using a transvaginal ultrasound. All women were started on ATT for 6 months by directly observed treatment strategy. After completion of ATT, all the parameters were repeated. RESULTS: There was a significant increase in AMH (2.68 ± 0.97 ng/ml to 2.8 ± 1.03 ng/ml) pre- to post-ATT, nonsignificant increase in FSH (7.16 ± 2.34 mIU/ml to 7.26 ± 2.33 mIU/ml) post-ATT, significant increase in mean AFC (7.40 ± 2.12-8.14 ± 2.17), PSV in the right ovary (6.015-6.11 cm/s) and left ovary (6.05-6.08 cm/s), PI in the right ovary (0.935-0.951 cm/s) and left ovary (0.936-0.957 cm/s), and RI in the right ovary (0.62 ± 0.01-0.79 ± 0.02) and left ovary (0.65 ± 0.02-0.84 ± 0.01) with ATT. There was no significant change in mean ovarian dimensions (ovarian length, breadth, and width) and summed ovarian volume with ATT. On laparoscopy, tubercles were seen in 27 (54%) women. Caseous nodules and encysted ascites were seen in 8% cases each. CONCLUSION: ATT improves the ovarian function (AMH and AFC) and ovarian blood flow in women with FGTB.
RESUMO
OBJECTIVE: To compare six months versus nine months anti-tuberculous therapy in patients of female genital tuberculosis. STUDY DESIGN: It was a randomized controlled trial in a tertiary referral center teaching institute on 175 women presenting with infertility and found to have female genital tuberculosis on clinical examination and investigations. Group I women (86 women) were given 9 months of intermitted anti-tuberculous therapy under directly observed treatment short course (DOTS) strategy while Group II (89 women) were given 6 months of anti-tuberculous therapy under DOTS. Patients were evaluated for primary end points (complete cure, partial response, no response) and secondary end points (recurrence rate, pregnancy rate) during treatment. All patients were followed up further for one year after completion of therapy to assess recurrence of disease and further pregnancies. RESULTS: Baseline characteristics were similar between two randomized groups. There was no difference in the complete clinical response rate (95.3% vs 97.7%, p=0.441) between 9-months and 6-months groups. Four patients in 9-months group and two patients in 6-months group had recurrence of disease and required category II anti tuberculous therapy (p=0.441). Pregnancy rate during treatment and up to one year follow up was also similar in the two groups (23.2% vs 21.3%, p=0.762). Side effects occurred in 27(31.4%) and 29(32.6%) in 9-months and 6-months of therapy and were similar (p=0.866). CONCLUSIONS: There was no difference in complete cure rate, recurrent rate and pregnancy rate for either 6-months or 9-months of intermittent directly observed treatment short course anti-tuberculous therapy in female genital tuberculosis. CLINICAL TRIAL REGISTRATION: The trial was registered in clinicaltrials.gov with registration no: CTRI/2009/091/001088.

PURPOSE: Side effects related to radiation exposures are based primarily on the assumption that the detrimental effects of radiation occur in directly irradiated cells. However, several studies have reported over the years of radiation-induced non-targeted/ abscopal effects in vivo that challenge this paradigm. There is evidence that Cyclooxygenase-2 (COX2) plays an important role in modulating non-targeted effects, including DNA damages in vitro and mutagenesis in vivo. While most reports on radiation-induced non-targeted response utilize x-rays, there is little information available for heavy ions. METHODS AND MATERIALS: Adult female transgenic gpt delta mice were exposed to an equitoxic dose of either carbon or argon particles using the Heavy Ion Medical Accelerator in Chiba (HIMAC) at the National Institute of Radiological Sciences (NIRS) in Japan. The mice were stratified into 4 groups of 5 animals each: Control; animals irradiated under full shielding (Sham-irradiated); animals receiving whole body irradiation (WBIR); and animals receiving partial body irradiation (PBIR) to the lower abdomen with a 1 x 1 cm2 field. The doses used in the carbon ion group (4.5 Gy) and in argon particle group (1.5 Gy) have a relative biological effectiveness equivalent to a 5 Gy dose of x-rays. 24 hours after irradiation, breast tissues in and out of the irradiated field were harvested for analysis. Induction of COX2, 8-hydroxydeoxyguanosine (8-OHdG), phosphorylated histone H2AX (γ-H2AX), and apoptosis-related cysteine protease-3 (Caspase-3) antibodies were examined in the four categories of breast tissues using immunohistochemical techniques. Analysis was performed by measuring the intensity of more than 20 individual microscopic fields and comparing the relative fold difference. RESULTS: In the carbon ion group, the relative fold increase in COX2 expression was 1.01 in sham-irradiated group (p > 0.05), 3.07 in PBIR (p < 0.05) and 2.50 in WBIR (p < 0.05), respectively, when compared with controls. The relative fold increase in 8-OHdG expression was 1.29 in sham-irradiated (p > 0.05), 11.31 in PBIR (p < 0.05) and 11.79 in WBIR (p < 0.05), respectively, when compared with controls. A similar increase in γ-H2AX expression was found in that, compared to controls, the increase was 1.41 fold in sham-irradiated (p > 0.05), 8.41 in PBIR (p < 0.05) and 10.59 in WBIR (p < 0.05). Results for the argon particle therapy group showed a similar magnitude of changes in the various biological endpoints examined. There was no statistical significance observed in Caspase-3 expression among the 4 groups. CONCLUSIONS: Our data show that both carbon and argon ions induced non-targeted, out of field induction of COX2 and DNA damages in breast tissues. These effects may pose new challenges to evaluate the risks associated with radiation exposure and understanding radiation-induced side effects.

A retrospective analysis of eleven pregnancies complicated by isolated fetal congenital complete heart block (CCHB) in anti-SSA/Ro antibody positive women was carried out at a tertiary hospital in India to study the perinatal outcome. The mean gestational age at the time of detection of fetal CCHB was 24.5 ± 3.1weeks. Six mothers were asymptomatic; two had Sjögren's syndrome and three had systemic lupus erythematosus. Oral dexamethasone was given to all the patients after the diagnosis was made. There was one case of intrauterine death. Seven (63.6%) neonates needed a permanent pacemaker. There was no significant difference in the perinatal outcome in asymptomatic women with fetal CCHB and in women with connective tissue disorder and fetal CCHB. To conclude, fetal CCHB is associated with high morbidity but the presence of underlying connective disorder in the mother does not worsen the prognosis of the affected neonate.

AIM: The aim of this study was to evaluate the role of dehydroepiandrosterone (DHEA) supplementation on the ovarian reserve markers in infertile patients who were poor responders in previous in vitro fertilization (IVF) cycles. STUDY DESIGN: A prospective clinical trial was conducted on 30 patients with history of poor response in previous IVF cycles. These patients were treated with DHEA, (Tab Eema-D, Corona Remedies Pvt Ltd., Ahmedabad, Gujurat, India) 25 mg thrice a day for four months. Ovarian stimulation was done using the previous protocol. Clinical parameters were measured before and treatment with DHEA. Results were analysed using Student's "t" paired test. RESULTS: DHEA resulted in a significant increase (p < 0.05) in the serum Antimullerian hormone in all age groups (35, 36-38 and >38 years). Peak estradiol level on the day of human chorionic gonadotrophin administration also increased significantly (p < 0.05). A significant decrease (p < 0.05) was noted in Day 2 follicle-stimulating hormone (FSH) in all age groups. There was no statistically significant difference in the antral follicle count (AFC). Pregnancy rate was 16.7% after treatment. Thus, DHEA has a significant effect in improving the ovarian reserve in poor responders with previously failed IVF cycles. It can help in enhancing clinical pregnancy rate in these patients.

BACKGROUND: Pelvic floor dysfunction and prolapse affect 50 % of women past middle age. Failure to recognize the complex set of pelvic floor defects in individuals leads to most post-surgical failures. Imaging has so far not had an established role in the investigation of prolapse. The present study is an attempt to define the role of magnetic resonance imaging in POP. MATERIALS AND METHODS: Thirty patients with clinically graded stage III/IV prolapse underwent routine physical examination and grading of POP in the Department of Obstetrics and Gynaecology, AIIMS. Dynamic MR evaluation with TRUFISP configuration was done and organ prolapse was measured through the hiatal line (HMO classification). The agreement of MRI, physical examination and intra-operative examination was analyzed using kappa as the test of agreement. OBSERVATIONS AND RESULTS: Twenty-eight subjects with grade III and 2 subjects with grade IV prolapse were enrolled. The mean age was 52.8 and the mean parity was 3.63. On MRI, 19 patients were found to have grade III prolapse, 4 had grade IV prolapse and the rest had grade I and II prolapse. There was poor agreement of MRI with clinical examination in anterior and middle compartments (k 0.161, k 0.144). The agreement between MRI and Intra-operative findings was 0.369, 0.422 for anterior and posterior compartments. Kappa was 0.085 for rectocele and 0.710 for enteroceles. The agreement was better for posterior compartment and enterocele. MRI detected 5 out of 8 enteroceles intra-operatively. CONCLUSION: The study demonstrates that while dynamic MRI does not confer any additional advantage in the diagnosis of anterior and middle compartment defects, the diagnosis of enteroceles, which may be missed clinically, is efficiently made on dynamic MRI imaging. Additionally, MRI can differentiate enterocele from a high rectocele which can further classify the surgery needed. There is also a need to standardize the protocol and the role of MR imaging in POP.

The hierarchical virtual screening (HVS) study, consisting of pharmacophore modelling, docking and VS of the generated focussed virtual library, has been carried out to identify novel high-affinity and selective ß(3)-adrenergic receptor (ß-AR) agonists. The best pharmacophore model, comprising one H-bond donor, two hydrophobes, one positive ionizable and one negative ionizable feature, was developed based on a training set of 51 ß(3)-AR agonists using the pharmacophore generation protocol implemented in Discovery Studio. The model was further validated with the test set, external set and ability of the pharmacophoric features to complement the active site amino acids of the homology modelled ß(3)-AR developed using MODELLER software. The focussed virtual library was generated using the structure-based insights gained from our earlier reported comprehensive study focussing on the structural basis of ß-AR subtype selectivity of representative agonists and antagonists. The HVS with the sequential use of the best pharmacophore model and homology modelled ß(3)-AR in the screening of the generated focussed library has led to the identification of potential virtual leads as novel high-affinity and selective ß(3)-AR agonists.

OBJECTIVES: To evaluate the outcome of hysteroscopic septal resection in patients with infertility and recurrent abortions. MATERIALS AND METHODS: This was a retrospective clinical analysis of 170 patients who underwent hysteroscopic septal resection by monopolar electrode (Collin's) knife. A second-look office hysteroscopy was performed in all cases within 2 months. The mean follow-up period was 28.5 months. RESULTS: The mean age of the patients was 25.6 years. The presenting clinical complaint was recurrent abortions in 68.2% patients, infertility in 17.6% patients and preterm deliveries in 14.1% patients. Final reproductive outcome was assessed for 152 patients, after excluding patients with other confounding factors, interfering in pregnancy outcome. There was a significant difference in reduction of number of miscarriages (91.5% pre-surgery; 12.9% post-surgery: p = 0.02) and increase in term deliveries (2.5% pre-surgery; 79.5% post-surgery: p = 0.01), while the number of preterm deliveries remained almost the same (6.1% pre-surgery; 7.5% post-surgery). Thirteen out of 23 infertile patients (56.5%) conceived after septal resection. The take home baby rate was increased from 8.5 to 87.1%. Cumulative first live birth rate revealed that 51.2% women had their first live birth within 10-15 months. There was an increased incidence (43.2%) of cesarean section in mode of delivery. In 11/170 patients, repeat hysteroscopy suggested the presence of uterine adhesions which needed hysteroscopic adhesiolysis and three patients required repeat septal resection. CONCLUSIONS: Hysteroscopic septal resection for women with history of recurrent abortions, preterm deliveries and in women with infertility is a safe and effective method of choice for improving the obstetric outcome.
