OBJECTIVETo evaluate the antioxidant potential in herbal extract barks of five therapeutically important medicinal plants native to India, i.e. Crataeva nurvala Buch.-Ham., Buchanania lanzan Spreng., Aegle marmelos Corr., Dalbergia sissoo Roxb. ex DC., and Cedrela toona Roxb.
METHODSStandardized aqueous alcoholic extracts from the selected barks having different target radicals, such as superoxide radical, nitric oxide, ABTS radical, and peroxidative decomposition of phospholipids, were prepared and screened by multiple in vitro assays. These extracts were also tested for total phenolic and tannin content and correlated with antioxidant capacity.
RESULTSTotal phenolic and tannin contents were found to be the highest in C. nurvala (195 GAE mg/g and 218.3 mg/g CE). SOD mimetic activity was found to be the highest in Crataeva nurvula, although all barks showed activity more than 100 units/mg extract. Lipid peroxidation inhibitory potential was found to be the highest in Crataeva nurvala (83.4% inhibition of MDA formation/10 microg extract), and also showed a comparatively high NO quenching capacity (45.5% per 10 microg extract). The highest NO quenching potential was found in Aegle marmelos (47.3% per 10 microg extract). Cedrela toona showed the lowest LPO inhibitory potential and NO quenching capacity (50.5% and 30.5%, respectively). Buchanania lanzan, a medicinal plant extensively used for inflammatory disorders and Dalbergia sissoo also showed 72.5% and 69.1% LPO inhibitory potential/10 microg extract. Trolox equivalent antioxidant capacity ranged from 0.24 to 0.39 mmol/L TEAC/mg extract, indicating that all the barks tested had ABTS+ radical quenching capacity.
CONCLUSIONBark of Crataeva nurvula has the highest antioxidant capacity and a positive correlation between antioxidant activity and their plendic content was found.

Objectives:
To evaluate the effect of levonorgestrel-releasing intrauterine system (LNG-IUS) on heavy menstrual bleeding in perimenopausal women.
Methods:
This was a prospective, observational clinical study conducted on 42 perimenopausal women with heavy menstrual bleeding who met the study eligibility criteria. LNG-IUS was inserted in the postmenstrual phase following baseline evaluation. The patients were followed up at the 4, 12, and 24 weeks. Pictorial blood assessment chart (PBAC) score, hemoglobin and serum ferritin levels, and endometrial thickness were assessed before insertion and during the follow-up visits.
Results:
Two patients (4.8%) were lost to follow-up, three patients (7.1%) opted for hysterectomy, two women (4.8%) experienced spontaneous expulsion and 35 (83.3%) women continued the usage. Menstrual blood loss assessed using the median PBAC score (interquartile range) significantly reduced (P < 0.001) from the pre-insertion level of 280 (246–306) to 124 (60–200) at 4 weeks to 45 (34–76) at 12 weeks and further to 32 (20–50) at the end of 24 weeks. Simultaneously, a significant (P < 0.001) improvement in the mean hemoglobin and serum ferritin levels and a significant (P < 0.001) decrease in endometrial thickness were observed. The most common side effect was spotting (50.0%) and vaginal discharge (38.1%).
Conclusions
LNG-IUS causes a remarkable reduction in menstrual blood loss and marked improvement in dysmenorrhea. It also reduces anemia by improving the hemoglobin and ferritin levels. Thus, it can serve as an effective treatment option for heavy menstrual bleeding in perimenopausal women and prevent the need for a hysterectomy.

The major concern that has confronted surgeons during the COVID-19 pandemic is the risk of infection during surgery. So far, no studies have found SARS-CoV-2 in surgical smoke, and if it was found, whether it was infectious or not is unknown. To date, no evidence shows that respiratory viruses can be transmitted through a surgical plume or an aerosolized gas. There are various advantages of laparoscopy over laparotomy that must be kept in mind in the COVID-19 era, such as early recovery and shorter hospital stay, which can greatly help to conserve valuable hospital resources, and reduced risk of spillage of blood and body fluids, which can help to reduce transmission risk; most importantly, the distance between surgeons and between surgeons and patient is greater. Certain precautionary measures can be taken to reduce SARS-CoV-2 transmission during laparoscopy. Whenever possible, it should be the surgical option of choice.

Purpose:
Effective communication skills are essential for resident doctors to provide optimum patient care. This study was conducted to develop and validate a questionnaire for the self-assessment of resident doctors’ communication skills in India.
Methods:
This was a mixed-methods study conducted in 2 phases. The first phase consisted of questionnaire development, including the identification of relevant literature, focus group discussions with residents and experts from clinical specialties, and pre-testing of the questionnaire. The second phase involved administering the questionnaire survey to 95 residents from the Departments of Medicine, Emergency Medicine, Pediatrics, and Surgery at the All India Institute of Medical Sciences, New Delhi, India in April 2019. Internal consistency was tested and the factor structure was analyzed to test construct validity.
Results:
The questionnaire consisted of 3 sections: (A) 4 items on doctor-patient conflicts and the role of communication skills in avoiding these conflicts, (B) 29 items on self-assessment of communication skills in different settings, and (C) 8 items on barriers to practicing good communication skills. Sections B and C had good internal consistency (Cronbach α: 0.885 and 0.771, respectively). Section C had a 2-factor solution, and the barriers were classified as ‘training’ and ‘infrastructure’ factors.
Conclusion
This appears to be a valid assessment tool of resident doctors’ communication skills, with potential utility for identifying gaps in communication skills and developing communication skills modules.

Objective:
The novel coronavirus pandemic led to the suspension of elective surgeries and the diversion of resources and manpower towards pandemic control. However, gynecological emergencies and malignancies must be addressed despite the restricted resources and the need for protective measures against COVID-19. This study aimed to determine the types of gynecological surgeries performed, difficulties encountered, and their outcomes in the setting of the pandemic.
Methods:
We performed a prospective cohort study over 6 months at a single tertiary center, including 60 women with gynecological complaints, categorized as emergencies and semi-emergencies, who underwent further surgery. Their surgical outcomes were measured through various parameters.
Results:
We found that 68.3% were emergency cases, while the rest were classified as semi-emergencies. Fibroid and adenomyosis with failed medical management (48.3%), followed by cervical intraepithelial neoplasia (10%), and malignancies (10%) accounted for the semi-emergency cases, while ruptured ectopic pregnancies (13.3%) and torsion and ovarian cysts (18.4%) comprised the emergency cases. The decision to incision time between emergency and semi-emergency cases varied widely due to the safety prerequisites during the pandemic, ranging from 1 hour in emergency cases to 48 hours in semi-emergency cases. In addition, we studied the ease of preoperative preparation, patient satisfaction, and the average number of personnel available to run the operation theaters at these times. No serious perioperative adverse events were observed in the present study.
Conclusion
In conclusion, gynecological surgeries could continue to be safely performed with all precautions in place against COVID-19 infection and related morbidities.

Objective:
To study the efficacy and safety of 0.5% bupivacaine in paracervical block to reduce immediate postoperative pain after total laparoscopic hysterectomy.
Methods:
A prospective, randomized, double-blind, placebo-controlled study was conducted at a tertiary referral center involving thirty women each in the treatment and placebo groups. Paracervical block with 10 mL of 0.5% bupivacaine (treatment group) or 0.9% saline (placebo group) was administered following general anesthesia and prior to proceeding with total laparoscopic hysterectomy. Visual analogue scale (VAS) scores at 30 and 60 minutes post extubation and mean VAS score (average VAS score at 30 and 60 minutes) were compared. Adequate pain control was defined as mean VAS score ≤5. Additional postoperative opioid requirement, hospital stay, and readmissions were also compared.
Results:
Baseline variables such as age, previous history of cesarean section, operating time, and weight of the specimen were comparable in both groups. VAS scores at 30 (5.0±2.8 vs. 7.0±1.4) and 60 minutes (5.2±2.8 vs. 7.0±0.8) and the mean VAS score (5.1±2.7 vs. 6.8±0.9) were significantly lower in the treatment group. Adequate pain control (mean VAS score ≤5) was 57% higher and additional opioid consumption was 47% lower in the treatment group. No significant difference was found in the duration of hospital stay and readmission rate.
Conclusion
Paracervical block with bupivacaine was useful in reducing immediate postoperative pain with a 25% reduction in mean VAS score and a 47% reduction in opioid consumption in the first hour after total laparoscopic hysterectomy.
