Abstract
Immune checkpoint inhibitors (ICIs) have revolutionized the treatment paradigm of mismatch repair-deficient/microsatellite instability-high (MMMR-D/MSI-H) colorectal cancer (CRC). Unique molecular features of MMR-D/MSI-H CRC with frameshift alterations, which result in mutation-associated neoantigen (MANA) generation, create an ideal molecular framework for MANA-driven T-cell priming and antitumor immunity. These biologic characteristics of MMR-D/MSI-H CRC resulted in rapid drug development with ICIs for patients with MMR-D/MSI-H CRC. Observed deep and durable responses with the use of ICIs in advanced-stage disease have stimulated the development of clinical trials with ICIs for patients with early-stage MMR-D/MSI-H CRC. Most recently, neoadjuvant dostarlimab monotherapy for nonoperative management of MMR-D/MSI-H rectal cancer and neoadjuvant NICHE trial with nivolumab and ipilimumab for MMR-D/MSI-H colon cancer resulted in groundbreaking results. Although nonoperative management of patients with MMR-D/MSI-H rectal cancer with ICIs will potentially define our current therapeutic approach, therapeutic goals of neoadjuvant ICI therapy for patients with MMR-D/MSI-H colon cancer may differ given that nonoperative management has not been well established for colon cancer. Herein, we overview recent advancements in ICI-based therapies for patients with early-stage MMR-D/MSI-H colon and rectal cancer and elaborate on the future treatment paradigm of this unique subgroup of CRC.

Abstract
Soft tissue deposits, also known as tumour deposits (TDs), have not been studied well in head and neck squamous cell carcinoma (HNSCC) and are not included in any of the staging systems or treatment guidelines. The aim of this systematic review was to determine the prevalence and prognostic implications of TDs in patients with HNSCC. This systematic review of the literature was conducted following the PRISMA guidelines. The PubMed, Embase, and Scopus electronic databases were searched for relevant studies, from inception to August 2022. Although 14 studies qualified for inclusion, only eight were finally included in the review due to the considerable overlap of patients in several studies. Data from 7127 patients were analysed. The pooled prevalence of TDs was 21% (95% confidence interval (CI) 9-33%). The presence of TDs was adversely associated with overall survival and disease-free survival, with hazard ratios of 2.08 (95% CI 1.60-2.70) and 2.56 (95% CI 1.97-3.32), respectively. TDs are detected in a significant number of patients with HNSCC and adversely affect survival. Longitudinal prospective studies are needed to evaluate the prognostic implications of TDs in HNSCC for their potential role in cancer staging and adjuvant treatment planning.

Abstract
Towards an efficient, low-cost solution to the problem of contamination of groundwater by selenium leached out from earth's mineral crust, a new system is developed using a novel graphene-based nanocomposite membrane. The system not only purified selenium-contaminated groundwater with high degree but also ensured safe disposal of the rejected selenium through algorithmic chemical stabilization in a mineral matrix. All experiments were conducted with live contaminated water from selenium affected area rather than using synthetic solution in a semi-pilot unit involving a largely fouling-free flat sheet cross-flow membrane module. Pure water flux of up to 190 Lm-2h-1(LMH) with 96-97% selenium rejection at an optimum operating pressure of only 14 bar could be achieved. Rejected selenium was stabilized in mineral matrix through chemical coagulation-precipitation using suitable coagulants following prior optimization of the critical operating parameters by Model-based calibration toolbox (MATLAB R2020a). A high degree of stabilization efficiency (99.8%) could be achieved as reflected in an error-index of only 1.13%. For selenium-affected region, the membrane-integrated hybrid treatment system proved to be a potential candidate technology offering safe drinking water at an approximate cost of only 1.77 $/m3 which was found to be affordable to the consumers in subsequent willingness to pay survey.

Abstract
Aicardi-Goutières syndrome type 6 (AGS6) and dyschromatosis symmetrica hereditaria (DSH) are allelic disorders caused respectively by biallelic and heterozygous pathogenic variants in ADAR1. We report three unrelated children presenting with features of both AGS6 and DSH, two of whom had compound heterozygous pathogenic variants in ADAR1. We also describe the novel genetic variants in our cases and review the literature on association of ADAR1-related AGS6 and DSH with these phenotypes.

Abstract
Introduction
Switching of medications for insomnia occurs often in clinical practice based on a variety of reasons. However, few clinical studies have examined methods for transitioning patients between different insomnia medications. This is especially important to consider when the classes of drugs are different (e.g., GABA-ergic agonism vs orexin receptor antagonism); thus, clinical guidance would be valuable. The safety and efficacy of the dual orexin receptor antagonist lemborexant (LEM) for the treatment of insomnia was confirmed in two Phase 3 studies, SUNRISE-1 (NCT02783729, E2006-G000-304) and SUNRISE-2 (NCT02952820, E2006-G000-303). This pilot study (NCT04009577, E2006-A001-312) was designed to assess pre-specified dosing approaches for directly transitioning from the sedative-hypnotic zolpidem (ZOL), a commonly prescribed sleep aid, to LEM.
Methods
This multicenter pilot study has enrolled subjects age ≥18 years with an insomnia diagnosis (DSM-5 criteria), who used ZOL (intermittently or frequently) as their only insomnia treatment. Following a 3-week Screening period, eligible subjects enter the Treatment Phase (2-week titration period: assigned to 1 of 3 treatment arms based on ZOL use during Screening), and then the Extension Phase (maintenance period up to 12 weeks). During both the Treatment and Extension Phases, the dose of LEM is flexible between 5 and 10 mg, depending on efficacy and tolerability. The primary endpoint is to evaluate the proportion of subjects taking ZOL who successfully transition to LEM (lemborexant 5 mg [LEM5] or lemborexant 10 mg [LEM10]) after 2 weeks of LEM treatment.
Results
Enrollment began July 15, 2019. It was initially projected that approximately 110 subjects would be screened to provide about 60 subjects for randomization across 3 treatment arms. Interim data will be presented (planned cutoff date Jan 08, 2020).
Conclusion
This pilot study will help inform on dosing guidance when transitioning a patient from a GABA-ergic drug to an orexin receptor antagonist.

Abstract
Abstract
Introduction
Patients who take insomnia medication may change medications for reasons including lack of efficacy, adverse events, and dependence concerns. A pilot study (NCT04009577, E2006-A001-312) assessed a dosing approach for transitioning patients from zolpidem tartrate (ZOL; immediate or extended-release) to lemborexant, a dual orexin receptor antagonist. Here we describe characteristics of subjects who entered the study Screening Period and their reasons for wanting to change medications.
Methods
This multicenter pilot study was conducted in the U.S. and enrolled subjects age ≥18y with insomnia diagnosed per DSM-5 criteria, and who used ZOL (self-reported intermittently [3-4 nights/week] or frequently [≥5 nights/week]) as their only insomnia treatment. Subjects entered a 3-week Screening Period, during which frequency/dose of ZOL taken was recorded; subjects also wore an actigraph continuously. Eligible subjects thereafter entered the Treatment Phase to determine lemborexant dosing (5 or 10mg during a 2-week Titration Period with assignment to 1 of 3 treatment schedules based on ZOL usage frequency during Screening), followed by a 12-week Extension (Maintenance) Phase and a 4-week Follow-up Period.
Results
Forty-nine subjects entered the Screening period and completed the Chief Complaint Form through November 2019; mean(SD) age was 57.1(13.8)y, 67.3% were female, 69.4% were white, and 28.6% were black. 31 subjects reported using ZOL frequently and 15 reported using ZOL intermittently (3 missing). The most common sleep complaint was waking up too early (n=33), followed by difficulty staying asleep (n=13), and difficulty falling asleep (n=3). Reasons for wanting to switch from ZOL included: ZOL not working (n=19), concerns about taking ZOL (n=14), wanting to try something new/potentially better (n=6), side effects (n=5), and residual daytime sleepiness (n=4). 43/49 subjects completed screening through this period.
Conclusion
This study offers the opportunity to understand patients’ current use of insomnia medication and their motivation for wanting to change insomnia medications.

Abstract
STUDY OBJECTIVES To evaluate weight loss with lorcaserin in persons with obstructive sleep apnea (OSA). METHODS This retrospective analysis evaluated weight loss of lorcaserin (10 mg twice daily) versus placebo in persons with obesity or overweight persons with OSA from a pooled database of three randomized, controlled trials. Primary end points were reductions in the baseline body weight of ≥5% and ≥10% at year 1 and overall weight change at year 1. Changes in heart rate and blood pressure were also evaluated. RESULTS A total of 336 persons with OSA were identified in the overall pooled population (N = 6,636). At year 1, more patients receiving lorcaserin lost ≥5% (47.2% lorcaserin vs. 25.6% placebo; p < 0.0001) and 10% (22.2% lorcaserin vs. 13.1% placebo; p < 0.0354) of their baseline body weight. Weight loss at year 1 was 6.4 kg versus 3.5 kg in the lorcaserin and placebo groups, respectively (p < 0.0001). Similar results were observed for change in blood pressure and heart rate, with responders having larger benefits. Weight loss was similar between persons with and without OSA. CONCLUSIONS In this retrospective analysis, persons with OSA showed significant and meaningful weight loss, blood pressure and heart rate reductions in patients treated with lorcaserin versus placebo. Persons with OSA lost just as much weight as those without OSA. Health care providers can expect persons with OSA to lose weight by diet, exercise and the weight loss medication lorcaserin comparable with persons without OSA. Further prospective research is warranted to evaluate impact of weight loss on OSA and overall outcomes for patients.

Abstract
INTRODUCTION The elderly population is projected to be the fastest growing group of individuals with obesity group in the United States. As such, there is merit in examining factors that contribute to healthy aging and weight management. The effects of newer weight loss medications approved after 2013 have been studied but are not often assessed specifically in older persons. METHODS This post hoc analysis evaluated the magnitude of weight loss in adults across age quartiles with lorcaserin, a serotonin (5-HT) 2C receptor agonist indicated as an adjunct to a reduced-caloric diet and increased physical activity for chronic weight management. Data from three lorcaserin pivotal phase 3 studies were used in this analysis. Data for patients with overweight/obesity without type 2 diabetes (T2D; BLOOM/BLOSSOM; body mass index [BMI] 27.0-29.9 kg/m2 and ≥1 comorbidity or BMI 30.0-45.0 kg/m2) and patients with overweight/obesity with T2D (BLOOM-DM; BMI 27.0-45.0 kg/m2) were used. Patients were randomized to receive lorcaserin 10 mg twice daily or placebo in addition to diet and exercise for 52 weeks. Age quartiles between the studies differed as the T2D population was on average, 9 years older. RESULTS This analysis shows that lorcaserin was associated with improved weight loss relative to placebo regardless of age. Importantly, these results were consistent for patients with and without T2D. Interestingly, the magnitude of weight loss for lorcaserin appeared to increase with increasing age. In patients without T2D, odds of achieving ≥5% and ≥10% reduction in body weight at 52 weeks were significantly higher for patients >36 years. Lorcaserin was well tolerated in all patients across all quartiles including the oldest quartile. CONCLUSIONS In summary, this post hoc analysis demonstrates that lorcaserin treatment in patients with and without T2D was safe and effective at reducing weight across all age groups analysed. Weight loss appeared to be greater for older patients; additional analyses are warranted to confirm these findings and to better understand the factors for improved weight loss.

Abstract
OBJECTIVE Weight management pharmacotherapies can improve metabolic diseases through weight-dependent and weight-independent effects. Lorcaserin is a selective 5-hydroxytryptamine 2C receptor agonist. The objective of this analysis is to quantify the relative contribution of weight loss to the treatment effects of lorcaserin 10 mg twice a day on key metabolic parameters. METHODS This retrospective analysis evaluated 6,897 patients with overweight or obesity (with or without diabetes mellitus) across three randomized, placebo-controlled, double-blind, 52-week clinical trials that evaluated lorcaserin 10 mg twice daily (BID; NCT00395135, NCT00603902, and NCT00603291); 509 patients from only one of the studies had type 2 diabetes mellitus. A mediation analysis was applied to help rank the relative contribution of weight loss to metabolic study outcomes. RESULTS According to this mediation analysis, lorcaserin 10 mg BID improved a spectrum of adiposopathic metabolic abnormalities with varying contributions attributable to weight loss. Improvements in waist circumference and blood pressure were almost exclusively attributable to weight loss. Less than 50% of the improvement in glucose parameters (fasting blood glucose and haemoglobin A1c) were attributable to weight loss. CONCLUSIONS Across Phase III clinical trials, lorcaserin 10 mg BID improved multiple cardiometabolic parameters through both weight-loss dependent and independent mechanisms.

Abstract
Cardiovascular and coronary artery disease risk are correlated with cholesterol levels and are significant health concerns. Current cholesterol-lowering approaches includes lifestyle and diet modifications, as well as statins which presents numerous shortcomings. The probiotic bacteria, Lactobacillus fermentum NCIMB 5221 and NCIMB 2797, have demonstrated cholesterol-lowering potential in animal studies. However, there is a lack in understanding the mechanism(s) behind these observed effects. The goal of this work is to investigate, in vitro, the cholesterol-lowering mechanisms of these two strains. To determine the cholesterol-lowering mechanisms, probiotic cholesterol assimilation, colon epithelial adhesion and inhibition of cholesterol uptake by colon epithelial (Caco-2) cells were investigated. L. fermentum NCIMB 2797 (P=0.012) and NCIMB 5221 (P=0.003) assimilated cholesterol and their cell surface hydrophobicity was 70.30±8.85% and 55.60±2.59%, respectively. Both L. fermentum strains showed no significant impact (P>0.05) on Caco-2 cell viability. Of most interest, Caco-2 pre-exposure to L. fermentum NCIMB 5221 significantly decreased (P=0.015) cholesterol uptake, with 85.98±2.07% uptake compared to the untreated cells. Similarly, L. fermentum NCIMB 2797 probiotic cells significantly decreased (P=0.019) cholesterol uptake by Caco-2 cells, with 86.45±1.71% uptake observed compared to the control cells. The results demonstrate that L. fermentum NCIMB 5221 and L. fermentum NCIMB 2797 have the potential via various modes of action to lower cholesterol. Additional studies are required to understand the mechanism(s) of action behind probiotic cholesterol assimilation and behind the cholesterol uptake inhibition by colon epithelial cells.

Abstract
Oral diseases, specifically dental caries and periodontal disease, are characterised by increases in pathogenic microorganisms, increased demineralisation and increased inflammation and levels of inflammatory markers. Despite the therapeutic strategies, oral diseases have elevated prevalence rates. Recent work has demonstrated that probiotic bio-therapeutics can decrease oral pathogen counts, including caries-causing Streptococcus mutans and oral inflammation. The aim of this work was to investigate putative probiotic bacteria, selected for S. mutans inhibition and for their oral health-promoting characteristics. The probiotic bacteria were screened for S. mutans inhibition, probiotic bacteriocin activity, salivary pH modulation, probiotic nutrient (sucrose) competition, probiotic co-aggregation with S. mutans, bacterial attachment to oral epithelial keratinocytes, bacterial nitric oxide production and bacterial antioxidant activity. The results indicate that Lactobacillus reuteri strains NCIMB 701359, NCIMB 701089, NCIMB 702655 and NCIMB 702656 inhibited S. mutans to non-detectable levels (<10 cfu/ml). L. reuteri strains also demonstrated the highest antioxidant capacity of the tested strains (7.73-13.99 µM Trolox equivalents), suggesting their use as both caries and periodontal disease therapeutics. Although Lactobacillus fermentum NCIMB 5221 inhibited S. mutans at lower levels, it significantly buffered the pH (4.18) of saliva containing S. mutans, co-aggregated with S. mutans (10.09%), demonstrated high levels of sucrose consumption (138.11 mM) and successfully attached to gingival epithelial cells (11%). This study identified four L. reuteri strains and one L. fermentum strain to be further investigated as oral disease biotherapeutics.

Abstract
Spinal Cord injury (SCI) is one of the most devastating and demoralizing ailment for both the patient and the medical practitioner. However, with the better understanding of the pathophysiology, better imaging modalities and emphasis on immobilization and rehabilitation has provided a ray of hope to such patients. The initial care aims at immobilization and evacuation by the classical log roll method and focuses on life-saving procedures. Basic imaging should be augmented with an MRI in doubtful cases. Immobilization either external or internal should be followed by early efforts for rehabilitation. The use of steroids during the acute phase has become controversial. The focus of latest studies has shifted to neuroprotective and regenerative agents.

Abstract
OBJECTIVES To compare the pregnancy outcomes of women having valvular heart disease with the pregnancy outcomes of healthy women. METHODS A retrospective comparison of the maternal and fetal pregnancy outcomes of 312 women with valvular heart disease and 321 healthy women cared for at a tertiary care hospital during the same period. Statistical analysis was done using the chi(2)-test, with significance fixed at 0.05. RESULTS Women with valvular heart disease had a significantly higher incidence of surgical interventions during pregnancy than women in the control group [13.4% (balloon mitral valvotomy) vs. 0.6% (ovarian cystectomy)], congestive heart failure (5.1% vs. 0%, P<0.001), and mortality [0.64% (two women) vs. 0%]. Perinatal outcome was also more adverse in the valvular heart disease group than in the control group, with increased preterm delivery rate (48.3% vs. 20.5%), reduced birth weight (2434+/-599 g vs. 2653+/-542 g; P<0.001), and a higher incidence of APGAR scores less than 8 (8.3% vs. 4%; P<0.01). There was also a higher rate of instrumental delivery (9.9% vs. 3.4%). However, the rate of cesarean deliveries was similar in the two groups. CONCLUSIONS Pregnancy in women with valvular heart disease is associated with significantly higher maternal morbidity and adverse fetal outcomes and requires a team approach for optimal management.

Abstract
BACKGROUND Pelvic pain is common in adolescent girls in day-to-day practice. Severity, Affect, Family and Environment (SAFE) is a recent interview strategy to approach these patients and their families. AIM 1. To find the prevalence of pelvic pain in adolescent girls. 2. To find out the feasibility and acceptability of "SAFE" approach in evaluating chronic pelvic pain in adolescent girls. SETTINGS & DESIGN 200 adolescent girls aged 13-23 years were selected at random from school and colleges nearby hospital campus. METHOD A questionnaire method was adopted. Adolescent girls selected were divided into two groups, group I (with pain) and group II (without pain). STATISTICAL ANALYSIS It was performed using chi-square and Fischer tests with significance of p value being taken at 0.05. RESULTS Out of 200 adolescent girls selected for interview, prevalence of pelvic pain was found to be 37.0%. Dysmenorrhoea was also found to have significant relationship with pelvic pain. Depression and anxiety, school absences and loss of weight were found to have significant association with pain. Pelvic pain was found to be more in adolescent girls with large family size (> 4 members), single parent, both parents working, ongoing marital problems at home and was less reported when there was good parent-child communication about sex and when the teenager was well prepared for menarche by the parents and the association with the above mentioned factors was found to be significant. CONCLUSION "SAFE" approach contributes in identifying health problems in adolescent girls with chronic pelvic pain.

Abstract
A questionnaire-study was undertaken among 50 women to take note of their views on awareness, information, choices and expectations on various aspects of hysterectomy performed on them. Most women (92%) did not know the type of hysterectomy and none of them was offered the alternative treatment, various types of hysterectomy done, type of anaesthesia used and hormone replacement therapy. A total of 96% wanted the surgeon to spend time with them explaining to them about various aspects of surgery and 46% thought the staff was sympathetic to them. A total of 26 women (52%) preferred to solve their problems with self-help groups (association of women with similar problems) and 84% wanted a leaflet to be distributed to them about various aspects of hysterectomy. This study concluded that Indian women to be involved in the decision making about their healthcare.

Abstract
BACKGROUND As ectopic pregnancy is associated with significant maternal mortality and morbidity it may be worthwhile to find alternative surgical method to traditional laparotomy. AIMS To compare the efficacy, safety and cost effectiveness of minilaparotomy surgery for ectopic pregnancy cases with standard laparotomy method. SETTING AND DESIGN A total of 60 patients of ectopic pregnancy were randomized for minilaparotomy and laparotomy (30 cases each) for three years from January. 1998 to March 2001 in a medical college hospital. MATERIAL AND METHODS Patients history, clinical examination, intraoperative, preoperative and postoperative data were recorded and compared in minilaparotomy and laparotomy groups. STATISTICAL ANALYSIS USED Chi-square and Fischer chi-square test is used using P value of less than 0.05 as level of significance. RESULTS Mean operative time was significantly less in minilaparotomy (38 minutes) than in laparotomy group (54 minutes). Postoperative complications were fever in 4(13.33%) and 6(20%) cases, paralytic ileus in 3(10%) and 8(26.66%) cases, urinary tract infection in 2(6.66%) and 3(10%) cases and wound infection in 1(3.33%) and 5(16.66%) cases respectively in the two groups and were significantly less in the minilaparotomy cases. Mean day of mobility, starting normal diet and discharge from the hospital were 10 hours and 24 hours, 1.5 days and 3.1 days and 3.4 days and 6.9 days respectively in the two groups and were significantly less in the minilaparotomy group than the laparotomy group. CONCLUSIONS Surgery by minilaparotomy technique in ectopic pregnancy cases appears to be a safe and feasible method and is superior to conventional laparotomy as there are minimum perioperative and postoperative complications and patients can be discharged early from the hospital without the need of expensive equipment.

Abstract
OBJECTIVES To test the efficacy and safety of laparoscopic oxidized cellulose application at the uterine perforation site. METHODS In a prospective study over a 3.5-year period a total of 30 women undergoing combined surgical termination of pregnancy and laparoscopic sterilization who had a small uterine perforation were recruited. Oxidized cellulose (Surgicel) was inserted and attached to the perforation site with a laparoscope. The end point was sealing of the perforation and complete hemostasis. Laparotomy was performed if hemostasis was not achieved. RESULTS The mean age, parity and gestation were 31.4 years, 3.8 and 9.3 weeks. The perforations occurred in the fundal region (60%), anterior wall (16.7%), posterior wall (13.3%), upper lateral wall (3.3%) and lower lateral wall (6.7%). Mean size of perforations, respectively according to site were 4.3 mm, 3.2 mm, 3.4 mm, 3 mm and 3.5 mm in the five groups. Laparoscopic oxidized cellulose application was successful in all women with fundal, anterior, posterior and upper lateral uterine wall perforations. In two women with perforations on the lower lateral wall, due to excessive blood loss, oxidized cellulose fell off; laparotomy was performed and hemostasis was achieved with sutures. All 28 laparoscopically-treated women were discharged on the next day in good condition with no complications. CONCLUSIONS Laparoscopic oxidized cellulose application appears to be a safe and effective treatment for small uterine perforations that are bleeding moderately.

Abstract
OBJECTIVES To observe the effect of the antioxidant lycopene on the occurrence of pre-eclampsia and intrauterine growth retardation in primigravida women. METHODS A total of 251 primigravida women were enrolled in this prospective, randomized controlled study in the second trimester. A total of 116 women were given oral lycopene (Group I) in a dose of 2 mg twice daily while 135 women were given a placebo (Group II) in the same dose until delivery. The criteria for recruitment included gestational age of 16-20 weeks, singleton pregnancy, absence of any medical complication and willingness on the part of the women to participate in the study. The women were followed-up until delivery for development of pre-eclampsia, mode of delivery and fetal outcome. RESULTS The two groups were comparable in their maternal characteristics. Pre-eclampsia developed in significantly less women in the lycopene group than in the placebo group (8.6% vs. 17.7%, P=0.043 by chi-square test). Mean diastolic blood pressure was significantly higher in the placebo group (92.2+/-5.98 mmHg vs. 86.7+/-3.80 mmHg, P=0.012). Mean fetal weight was significantly higher in the lycopene group (2751.17+/-315.76 g vs. 2657+/-444.30 g, P=0.049). The incidence of intrauterine growth retardation was significantly lower in the lycopene group than in the placebo group (12% vs. 23.7%, P=0.033). CONCLUSIONS The results of the present study suggest that the antioxidant lycopene reduces the development of pre-eclampsia and intrauterine growth retardation in primigravida women.

Abstract
OBJECTIVES To compare maternal and fetal outcomes in patients with non-operated valvular heart disease and patients who had surgery before or during pregnancy. METHODS The 308 women with valvular heart disease who delivered in this hospital in the last 8 years were divided into three groups. The 218 (70.7%) women in group 1 had no surgical intervention; the 42 (13.6%) women in group 2 underwent balloon mitral valvotomy during pregnancy; and the 48 (15.5%) women in group 3 had surgical intervention before pregnancy (35 had balloon mitral valvotomy, eight had mitral valve replacement, and five had mitral valve repair). Maternal and fetal outcomes were compared for these three groups. RESULTS The antenatal events differed significantly: 175 (80.3%), 40 (94.2%), and 46 (95.8%) patients in groups 1, 2 and 3, respectively, had uneventful pregnancies. In group 1, 14 (6.4%) patients had congestive heart failure (P>0.05) and 24 (11%) patients had cardiac arrhythmias, which was statistically significant. The rate of preterm deliveries did not differ significantly among the three groups. The groups did not differ in mean birth weight, mode of delivery, low birth weight, Apgar scores less than 8, stillbirths, neonatal death, or congenital anomalies. CONCLUSIONS Mitral valve surgery before or during pregnancy did not significantly improve maternal and fetal outcomes but decreased adverse events such as congestive heart failure and cardiac arrhythmias. It should be therefore performed only in selected cases.

Abstract
OBJECTIVES To assess the prevalence of incidental Fitz-Hugh-Curtis syndrome in women undergoing diagnostic laparoscopy for sterilization, infertility or chronic pelvic pain. METHODS This was a prospective study over a 4-year period in which a total of 320 women undergoing diagnostic laparoscopy for sterilization [Group I, 200 women (62.5%)], infertility [Group II, 60 women (18.7%)], or chronic pelvic pain [Group III, 60 women (18.7%)] were enrolled. After examination of the pelvic area and abdominal cavity, the liver area was visualized in all cases for evidence of perihepatitis and adhesions between liver and anterior abdominal wall or diaphragm (Fitz-Hugh-Curtis syndrome). Statistical analysis was performed using the chi-square test, with a P-value set at 0.05 for significance. RESULTS The mean age was similar in the three groups, while mean parity was obviously less in the infertility group. Fitz-Hugh-Curtis syndrome was observed in 16 women (8%) in Group I, 10 women (16.6%) in Group II, and 18 women (30%) in Group III. The prevalence was highest in Group III and the difference was statistically highly significant in Group III vs. Group I (P<0.001), and in Group III vs. Group II (P<0.01). It was higher in the infertility group than in the sterilization group (P<0.05 in Group II vs. Group I). CONCLUSIONS There was a very high prevalence of incidental Fitz-Hugh-Curtis syndrome in the chronic pelvic pain and infertility groups, and even in the sterilization group.

Abstract
The permeability of the cornea to drugs is clinically important because it is the major factor determining the efficacy of topically applied ophthalmic preparations. With this perspective, the present article gives a brief update and overview of corneal structure and proposed mechanisms of permeation. Physiological, physicochemical and formulation factors affecting drug permeation through cornea are highlighted. Influence of ocular penetration enhancers on drug permeation is also discussed.

Abstract
In vitro testing is useful for detecting pollen and fungal-allergen sensitivities in nasobronchial-allergy patients. However, allergen-coated discs or solid-phases supplied in kits do not contain all the relevant extracts. The present study was aimed to develop a safe and credible procedure of allergen coating on paper discs for allergy diagnosis by ELISA. Paper discs were coated with indigenous allergens using poly(vinyl alcohol) and glutaraldehyde. ELISAs were carried out to standardize the allergen-coated discs using skin-test-positive-patients' sera. The cut-off value (A) for ELISA was worked out by analysing normal human sera (NHS) and is based on the mean+/-2 S.D. for the NHS value. The allergen-coated discs, i.e. Centre for Biochemical Technology (CBT) discs, demonstrated excellent comparison with plate-binding method and Pharmacia discs [Prosopis juliflora (mesquite), critical value 0.879 at 5% probability+/-0.599, n=11, is significant]. Inter- and Intra-assay coefficients of variations ranged from 2.5-14.05% to 4. 8-11.5% with different allergens. Results of skin tests and ELISA with CBT discs showed 60-70% correlation.

Abstract
Transcorneal permeation of ketorolac from oil based ocular drops and ophthalmic ointments was studied in vitro, using goat cornea. Cumulative (%) permeation of ketorolac through cornea, was found to be maximum with 0.2% (w/v) ketorolac drops in sesame oil followed by formulations in corn oil and soyabean oil. Ketorolac 1% (w/v) drops in castor oil increased the quantity permeated but cumulative (%) permeation was less. Permeation profiles of ketorolac were in consistence with the partition characteristic of drug between oil and aqueous phase. Formulations favouring corneal permeation of ketorolac increased corneal hydration. Addition of benzyl alcohol, a preservative, to oil drops reduced permeation of ketorolac and corneal hydration indicating possible protective effect of benzyl alcohol against corneal damage. Permeation studies on ointment formulations containing either ketorolac acid or ketorolac tromethamine salt indicated better permeation for formulation containing ketorolac tromethamine aqueous solution. Thus for better transcorneal permeation, ketorolac 0.2% (w/v) drops, formulated in sesame oil, containing 0.5% v/v benzyl alcohol and ophthalmic ointment containing 0.5% (w/w) ketorolac tromethamine in dissolved state appear suitable.

Abstract
Retinoids inhibit the expression of migration inhibitory factor-related protein-8 (MRP-8), a marker of hyperproliferative or abnormal keratinocyte differentiation, in a retinoic acid receptor (RAR)-dependent manner in various cell culture systems. MRP-8 expression is also down-regulated in vivo in psoriatic lesions after topical application of an anti-psoriatic RARbeta/gamma-selective synthetic retinoid, tazarotene. We demonstrate that an MRP-8 promoter linked to a chloramphenicol acetyltransferase reporter (MRP8CAT) faithfully replicates the differentiation-specific regulation of the endogenous keratinocyte MRP-8 gene. Further, interferon gamma and serum-induced expression of MRP8CAT is inhibited by retinoid receptors in a ligand-dependent manner. We also show that NF-IL6 acts as a transcriptional enhancer of MRP-8, and that RARs inhibit MRP8CAT by inhibiting the enhancer action of nuclear factor-interleukin-6 (NF-IL6). The NF-IL6 antagonism function of RAR is a complex of the core of the DNA binding domain and the hydrophobic zipper region. This manuscript identifies NF-IL6 as another transcription factor, in addition to AP1, whose activity is inhibited by RAR in a ligand-dependent manner. The interdiction of NF-IL6-dependent signal transduction pathway by RARs may explain some of the therapeutic effects of retinoids in inflammatory and proliferative diseases.

Abstract
In vitro transcorneal permeation of ketorolac tromethamine from 0.5% w/v solutions containing equimolar (0.02 M) concentrations of citrate (pH 6.5), phosphate (pH 6.5 and 7), citrate-phosphate (pH 7) and borate (pH 7) buffers was studied using goat cornea. Cumulative % permeation was maximum with phosphate buffered drops of pH 6.5. The effect of pH and ionic strength on permeation of ketorolac tromethamine from buffered (phosphate) drops was next investigated. Cumulative % permeation of ketorolac tromethamine from buffered drops was pH dependent being maximum at pH 4.5. Adjustment of ionic strength of drops to 0.2 resulted in decreased permeation of drug. Permeation of ketorolac tromethamine from unbuffered drops of varying pH and ionic strength 0.2 was also pH dependent and was maximum at pH 4.5. Buffered drops of pH between 4.5-5.5, ionic strength 0.2, provided better permeation of drug compared to unbuffered drops of same pH and ionic strength. Above pH 6.5 unbuffered drops showed better permeation than buffered drops. Increase in molarity of phosphate buffer (pH 4.5) used in making drops, between 0 to 0.15 M increased permeation. Aqueous drops of ketorolac tromethamine formulated in 0.15 M phosphate buffer of pH 4.5 and ionic strength 0.2 showed maximum cumulative % permeation in vitro. Considering lacrimation induced drug loss in vivo, by buffer of high concentration, ketorolac tromethamine drops formulated in buffer of low molarity, pH 4.5 and ionic strength 0.2 appear suitable.
