Abstract
The purpose of this systematic review and meta-analysis is to conduct a comparative evaluation of partial and full pulpotomy techniques in cariously exposed teeth with symptoms indicative of symptomatic irreversible pulpitis. Databases such as PubMed, EMBASE, Cochrane, and Web of Science were searched. Studies evaluating and/or comparing clinical and/or radiographic success of partial and full pulpotomy in teeth diagnosed with irreversible pulpitis with a minimum of 12 months follow-up were included. The risk of bias (ROB) tool was used for the assessment of ROB. A meta-analysis was conducted to compare the healing outcome of partial and full pulpotomy. Three studies fulfilled the inclusion criteria, there was a low risk of bias in each of the five domains. Full pulpotomy had a higher success rate than partial pulpotomy, according to meta-analysis, but the difference was not statistically significant.

Abstract
Background Effective irrigation is crucial for successful endodontic treatment. Traditional irrigants like sodium hypochlorite (NaOCl) have been widely used, but there is a growing interest in exploring natural alternatives for their potential antimicrobial properties. Objective The study aims to compare the antimicrobial efficacy of Neem, Bitter Gourd, and NaOCl, with and without ultrasonic activation in managing primary endodontic infections. Materials and Methods Ninety patients were randomly assigned six groups (n = 15) Group 1: NaOCl, Group 2: NaOCl with passive ultrasonic irrigation (PUI), Group 3: Neem juice, Group 4: Neem juice with PUI, Group 5: Bitter gourd juice, and Group 6: Bitter gourd juice with PUI. Bacteriological samples were collected before (S1) and after (S2) shaping, plated on brain heart infusion agar, and colony counting was done after 24 h. Statistical Analysis Used Shapiro-Wilk test, one-way ANOVA, post hoc Tukey analysis, and paired t-test. Results All the groups demonstrated a significant reduction in bacterial count. Groups with PUI (2, 4, 6) demonstrated higher mean bacterial reduction than their counterparts without PUI (1, 3, 5). Conclusion Neem and Bitter gourd juices, particularly when used with PUI, demonstrated antimicrobial efficacy comparable to NaOCl with PUI.

Abstract
BACKGROUND The use of cutting seton (CS) for the management of cryptoglandular fistula-in-ano has remained controversial because of reports of fecal incontinence, postoperative pain, and extended healing time. The aim of this review was to provide the first synthesis of studies investigating the use of CS for the treatment of cryptoglandular fistula-in-ano. METHODS MEDLINE, Embase, and CENTRAL were searched up to October 2022. Randomized controlled trials and observational studies comparing CS with alternative interventions were included, along with single-arm studies evaluating CS alone. The primary outcome was fistula-in-ano recurrence, and secondary outcomes included incontinence, healing time, proportion with complete healing, and postoperative pain. Inverse variance random-effects meta-analyses were used to pool effect estimates. RESULTS After screening 661 citations, 29 studies were included. Overall, 1513 patients undergoing CS (18.8% female, mean age: 43.1 years) were included. Patients with CS had a 6% (95% CI: 3-12%) risk of recurrence and a 16% (95% CI: 5-38%) risk of incontinence at 6 months. CS patients had an average healing time of 14.6 weeks (95% CI: 10-19 weeks) with 73% (95% CI: 48-89%) of patients achieving complete healing at 6 months postoperatively. There was no difference in recurrence between CS and fistulotomy, advancement flap, two-stage seton fistulotomy, or draining seton. CONCLUSIONS Overall, this analysis shows that CS has comparable recurrence and incontinence rates to other modalities. However, this may be at the expense of more postoperative pain and extended healing time. Further comparative studies between CS and other modalities are warranted.

Abstract
PURPOSE/OBJECTIVE(S) A majority of patients with oligometastatic prostate cancer experience relapse within 12 months of metastasis-directed therapy. Intense, triple-agent androgen annihilation therapy (AAT) with leuprolide, abiraterone acetate plus prednisone (AAP), and apalutamide may improve efficacy, but long courses of AAT have been shown to be associated with increased rates of grade≥3 toxicity. The purpose of this secondary analysis of this study is to characterize the tolerability of a short, six-month course of AAT added to metastasis-directed therapy. MATERIALS/METHODS All 28 patients enrolled on this phase II study were included in this analysis. All patients had oligometastatic prostate cancer after initial radical prostatectomy, defined by the presence of 1-5 extrapelvic metastases on prostate-specific membrane antigen (PSMA) PET/CT. Patients were started on six months of AAT. After the first month, patients received stereotactic body radiotherapy (SBRT) in 1, 3, or 5 fractions to metastases with or without radiotherapy to the prostate bed and pelvic lymph nodes. Physician-scored toxicities were graded according to Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0. RESULTS Median follow-up time was 11.4 months. Twenty patients (71.4%) completed AAT with all three agents. Six patients (21.4%) completed six months of therapy but discontinued at least one agent [4 patients (14.3%) discontinued apalutamide, 1 patient (3.6%) discontinued AAP, and 1 patient (3.6%) discontinued both apalutamide and AAP]. Two patients (7.1%) withdrew from the trial due to adverse events and did not complete therapy. Grade 2 and grade 3 toxicity rates from AAT were each 21.4%. Of the 6 cases of grade 3 toxicity, 3 were skin rashes, 2 were hypertension, and 1 was hepatic toxicity. At the time of SBRT, 1 patient had withdrawn from the study and 1 patient declined radiation therapy. All 26 remaining patients completed SBRT. Grade 2 and grade 3 toxicity rates from SBRT were 7.7% and 0%, respectively. CONCLUSION A majority of patients were able to tolerate and complete AAT in combination with metastasis-directed SBRT. Some patients experienced acute grade 3 toxicities, the most common being drug-related skin rashes and hypertension. While efficacy data are needed to evaluate the oncologic benefit, these data suggest a short course of AAT is considerably better tolerated than longer courses of AAT, with grade 3 toxicity rates similar to long courses of single-agent androgen deprivation therapy alone.

Abstract
BACKGROUND In North India, the mining industry is disorganized and profit-driven. It predisposes its workers towards the development of silicosis. Haryana, a major North Indian state, has developed a compensation-rehabilitation policy for mining workers. AIMS This study is the review of the policy's functioning and limitation from the first 4 years of implementation. METHOD The labour department does surveillance of workers in the mining industry. All suspected cases of silicosis are evaluated by a multidisciplinary team. Based on the final diagnosis, the compensation is decided. RESULT Nearly 5000 workers were screened, and 729 appeared before the medical board. Of these 729, 465 were having silicosis, and their data are presented here (data of 7 patients were missing). All workers were males. The mean age was 44.54 ± 9.6 years, and the mean exposure (work experience) was 17.25 ± 6.7 years. Most of the workers were between the age of 40 and 50 years and had exposure for 10-20 years. Chest radiography examination showed that progressive massive fibrosis (large size type C opacities) was the most common type of presentation (23%). Smaller opacities (p, q, r and s, t, u) were combined for further analysis, given their similar prognostic significance. It was found that age and experience both had a linear and significant correlation with the severity of lung involvement. CONCLUSIONS Nearly a quarter of subjects were suffering from the worst type of lung involvement at screening itself. The policy has laid a foundation for the welfare of workers, but there is still a long way to go.

Abstract
Succinate dehydrogenase (SDH)-deficient renal cell carcinoma (RCC) accounts for 0.05-2% of all RCCs. The majority of patients have germline mutations, most frequently in the SDHB gene. People with these mutations are predisposed to developing paragangliomas, phaeochromocytomas and gastrointestinal stromal tumours. Patients should be referred to genetic services for further workup and close surveillance imaging due to the risk of development of further tumours. We present a woman with SDH-deficient RCC and review the literature associated with this uncommon entity.

Abstract
The present investigation deals with the preparation of multi-walled carbon nanotube (MWCNT)-doped plasticized polymer electrolyte. The nanocomposite has been prepared using solution casting method. Complex impedance spectroscopy study revealed the utmost room temperature conductivity of 5.6 × 10−4 S/cm when optimized plasticized polymer electrolyte (poly(ethyl methacrylate)+30% sodium iodide+60% ethylene carbonate) was doped with 7% MWCNT. Temperature dependence of conductivity showed Arrhenius behavior. The surface morphology and crystalline–amorphous deviation of the composite was observed using scanning electron microscope. Perfect complexation of various components of the composite was confirmed from Fourier-transform infrared spectroscopy and X-ray diffraction (XRD) data. The transference number measurement was done to calculate the proportionate amount of ionic and electronic conductivity. A dye sensitized solar cell has been fabricated using maximum ionic conductivity of solid polymer electrolyte and its electrical parameters measured at 1 sun condition.

Abstract
Molecularly Imprinted Polymers (MIPs) are synthetic receptors that are able to selectively bind their target molecule and, for this reason, they are currently employed as recognition elements in sensors. In this work, MIP nanoparticles (nanoMIPs) are produced by solid-phase synthesis for a range of templates with different sizes, including a small molecule (biotin), two peptides (one derived from the epithelial growth factor receptor and vancomycin) and a protein (trypsin). NanoMIPs are then dipcoated on the surface of thermocouples that measure the temperature inside a liquid flow cell. Binding of the template to the MIP layer on the sensitive area of the thermocouple tip blocks the heat-flow from the sensor to the liquid, thereby lowering the overall temperature measured by the thermocouple. This is subsequently correlated to the concentration of the template, enabling measurement of target molecules in the low nanomolar regime. The significant improvement in the limit of detection (a magnitude of three orders compared to previously used MIP microparticles) can be attributed to their high affinity, enhanced conductivity and increased surface-to-volume ratio. It is the first time that these nanosized recognition elements are used in combination with thermal detection, and it is the first report on MIP-based thermal sensors for determining protein levels. The developed thermal sensors have a high selectivity, fast measurement time (<5 min), and data analysis is straightforward, which makes it possible to monitor biomolecules in real-time. The set of biomolecules discussed in this manuscript show that it is possible to cover a range of template molecules regardless of their size, demonstrating the general applicability of the biosensor platform. In addition, with its high commercial potential and biocompatibility of the MIP receptor layer, this is an important step towards sensing assays for diagnostic applications that can be used in vivo.

Abstract
OBJECTIVE To assess the quality of maternity care in an Indian metropolitan city. STUDY DESIGN Three-stage cluster randomised cross-sectional survey. SETTING Sixty selected colonies of Delhi. POPULATION One thousand eight hundred and one subjects (of 2286 eligible) were enrolled from 118 446 houses. Women who had delivered a live viable birth in the past 6 months were selected for the study. METHODS In stage 1, 20 wards (of 150) were selected using a probability-proportionate-to-size systematic method. In stage 2, one colony from each income stratum (high, middle and low) was selected from each ward by simple random sampling. In stage 3, a house-to-house survey was conducted to recruit 30 women for administering a peer-reviewed and pilot-trialled questionnaire. MAIN OUTCOME MEASURES Caesarean section rate, induction rate and episiotomy rate. RESULTS National health targets such as iron supplementation advice (>96%), tetanus vaccination (>81%), and ≥3 antenatal visits (>90%) were largely achieved across health care facilities but not in home deliveries. Interventions were lower in public than private hospitals: caesarean section [23.7% (20.2-27.7) versus 53.8% (49.3-58.3)], induction [20.6% (17.5-24.25) versus 30.8% (26.8-33.2)] and episiotomy [57.8% (52.3-63.1) versus 79.4% (71.0-85.9)]. Private hospitals achieved better labour support rates [1.1% (0.5-2.2) versus 14.6% (8.5-24.1)] and pain relief [0.9% (0.4-2.0) versus 9.9 (6.5-14.8)]. Pubic hair shaving [16.2% (11.5-22.5) versus 36.4% (29.9-43.4)], enema [20.2% (15.5-26.0) versus 57.3% (49.5-64.8)], and IV fluids during labour [44.0% (36.2-52.2) versus 38.7% (29.3-49.1)] were widely prevalent in public and private hospitals. CONCLUSION Present practices fall short of evidence-based guidelines, with relative overuse of interventions in private hospitals and deficiency of patient-centred practices such as labour support in public hospitals.

Abstract
BACKGROUND Several randomized-controlled trials (RCTs) have sought to determine the efficacy of bovine lactoferrin in Helicobacter pylori eradication with equivocal results. AIM To evaluate the effect of bovine lactoferrin supplementation in H. pylori eradication. METHODS Electronic databases, reviews, bibliographies, abstracts and conference proceedings were searched. Included trials had to be randomized or quasi-randomized and controlled, using bovine lactoferrin in the intervention group, treating Helicobacter-infected subjects and evaluating eradication of H. pylori as an outcome. RESULTS The search identified five eligible RCTs (of 169). Data were available for 682 subjects (bovine lactoferrin group-n = 316; control group-n = 366). The pooled odds ratio (five studies) for eradication by intention-to-treat analysis was 2.22 (95% CI 1.44-3.44; P = 0.0003) using the fixed effects model (FEM) and 2.24 (95% CI 1.15-4.35; P = 0.0003) using the random effects model (REM) (Cochran's Q = 6.83; P = 0.145). The pooled risk difference was 0.11 (95% CI 0.05-0.16; P = 0.0001) by FEM (Cochran's Q = 6.67; P = 0.154) and 0.10 (95% CI 0.04-0.17; P = 0.0023) by REM. There was no significant difference in incidence of adverse effects. CONCLUSION Bovine lactoferrin potentially improves H. pylori eradication rates without any impact on adverse effects, but available evidence is limited and further research is necessary to confirm the findings.

Abstract
BACKGROUND Carbohydrate antigen 19.9 (CA19.9), a tumor marker for malignancies of the hepatobiliary tract and pancreas, has frequently been shown to be deranged in a number of non-malignant conditions that are associated with jaundice. This study aims to demonstrate the correlation between CA19.9 and serum bilirubin concentration in patients with benign conditions and to determine the frequency of a false-positive increase in CA19.9 in patients being investigated for potential HPB malignancies. METHODS This is a retrospective review of 83 consecutive patients presenting with an abnormal CA19.9 and radiological or clinical features suggestive of HPB malignancy subsequently shown to have benign disease. All patients were thoroughly investigated and followed up until the diagnosis of malignancy could be safely excluded. RESULTS Serum bilirubin, sodium, lymphocyte count, neutrophil:lymphocyte ratio (NLR), beta-human chorionic gonadotrophin (HCG), and age were found to correlate with CA19.9 by Pearson's correlation (P = 0.001, P = 0.006, P = 0.006, P < 0.001, P = 0.012, and P = 0.049, respectively). In multivariate regression analysis, bilirubin was identified as an independent variable that may predict CA19.9 level (P = 0.028). CONCLUSION CA19.9 level is significantly influenced by serum bilirubin and elevated levels have been observed in patients with non-malignant HPB conditions. Adjusting CA19.9 according to bilirubin levels is likely to improve the specificity of this antigen in the differential diagnosis of benign and malignant HPB diseases and its reliability in the monitoring of disease response to chemotherapy.

Abstract
21172 Background: Consumption of onion and garlic has been shown to give protection against various cancers. Motivated by this observation we intended to look at the cancer incidence in a population belonging to Jain religion that does not consume garlic and onion due to religious belief. This study was done to see cancer incidence in children of Jain religion as compared to other religions at a single centre. Methods: It was a retrospective analysis of consecutive children less than 16 years of age diagnosed with cancer at Sir Ganga Ram Hospital from January 2005 to January 2007. We excluded adult patients with cancer as tobacco and alcohol consumption in this age group would have been confounding factors.Age, sex and religion were noted. Data from Census of India for year 2001 was used to know distribution of various religions in general population alongwith literacy rates and proportion in 0–6 years age. Results: As per 2001 Census of India , distribution of population in India as per various religions is Hindu 80.5%, Muslim 13.4%, Christian 2.3%, Sikh 1.9%, Buddhist 0.8% , Jain 0.4% and others 0.6%. Proportion of population in 0–6 year of age in India is 15.9% and as per religions Hindu 15.6%, Muslim 18.7% ,Christian 13.5%, Sikh 12.8%, Buddhist 14.4% and Jain 10.6%. Literacy rates of India is 64.5% and by religion is Hindu 65%, Muslim 59.1% Christian 80.3%, Sikh 69.4%, Buddhist 72.7% and Jain 94%. Distribution of population in Delhi as per various religions is Hindu 82%, Muslim 11.7%, Christian 0.9%, Sikh 4%, Buddhist 0.2% and Jain 1%. Total of 201 patients were diagnosed with cancer and distribution as per religions was Hindu 162 (81%), Muslim 15 (7.5%), Christian 3 (1.5%), Sikh 8 (4%), Buddhist 1 (0.05%) and Jain 12 (6%). Conclusions: Incidence of cancer in children of different religions is similar to that of proportions of population of different religions in Delhi except for Jain religion where incidence of cancer is 6 times higher despite lesser number children in 0–6 year in this population as compared to other religions . Major difference is the diet lacking in onion and garlic . Other reason could be increased literacy levels in Jain community . This link between diet ,religion and cancer in Jain population needs to be studied in a larger muticenteric setting as it has implications for the whole world. No significant financial relationships to disclose.

Abstract
The formation of silver nanoparticles by chemical reduction of Ag+-loaded Nafion-117 membrane with NaBH4 was studied using radioactivity tagged ions. The counterion-exchange method (Ag(m)+ <--> Na(s)+) was used to obtain a membrane sample with a varying proportion of Ag+ ions. The X-ray elemental mapping across the thickness of the membrane by energy-dispersive X-ray spectrometer attached to the environmental scanning electron microscope (ESEM/EDAX) indicated that Na+ and Ag+ were uniformly distributed in the membrane samples before reduction. The average size of nanoparticles formed after reduction was found to be 15 +/- 3 nm, irrespective of the concentration of silver ions present in the membrane before reduction. Energy-dispersive X-ray fluorescence (EDXRF) analyses of the membrane samples, carried out before and after reduction, indicated that the Ag concentration on the membrane surface was considerably increased after reduction. EDXRF measurements of the membrane samples, obtained from reduction carried out in a dead end cell, indicated that Ag nanoparticles were formed only on the membrane surface exposed to NaBH4 solution. Reduction carried out with NaBH4 tagged with 22Na showed that the formation of Ag nanoparticles involved exchange of Ag+ ions from ion-exchange sites in the interior of the membrane with Na+ ions, followed by reduction of Ag+ ions with BH4- ions at the surface of membrane. The study of self-diffusion of water, Na+, and Cs+ ions in the membrane loaded with Ag nanoparticles indicated that formation of Ag nanoparticles did not affect the diffusional transport properties of the membrane. The ion-exchange capacity and water uptake capacity were also not affected by the formation of Ag nanoparticles in the membrane. The spatial distribution of Ag nanoparticles across the thickness of the membrane obtained by ESEM/EDAX showed that Ag nanoparticles were confined to a few-micrometer surface layer of the membrane. Based on these observations, an attempt has been made to explain the mechanism of the formation of Ag nanoparticles in the membrane.

Abstract
In Northern India, in an institution like ours which receives quite a number of patients from surrounding rural areas, we found groundnut as the most common foreign body of tracheobronchial tree in children particularly in winter months of October to January. This article attempts to address the potential hazard of groundnut inhalation in children.

Abstract
Breast epithelial response to estradiol may play an important role in breast cancer etiology. We have examined the relationship between serum estradiol and progesterone levels and normal breast epithelial expression of estrogen receptor (ER) alpha, progesterone receptor (PgR), and epithelial proliferation (as reflected by the Ki-67 labeling index) in 121 women (50 newly diagnosed breast cancer cases and 71 benign breast disease controls). Simultaneous samples of grossly normal breast tissue and venous blood were obtained from women undergoing breast surgery. Serum estradiol and progesterone levels were measured by radioimmunoassay; breast epithelial ER, PgR, and Ki-67 expression was measured by immunohistochemistry. Linear regression, controlled for patient age and ductal and lobular composition of the tissue, showed that the breast epithelium of control women displayed an inverse correlation between serum estradiol and ER-alpha, which was not seen in case women (P for the difference in regression slopes = 0.001). PgR expression displayed a significant positive correlation with serum estradiol in cases, but not in controls. Epithelial proliferation had no relationship to either estradiol or progesterone in both cases and controls but showed an inverse relationship with ER in controls and a direct relationship in cases (P for the difference in regression slopes = 0.066). These results suggest a dysregulation of hormonal response in the normal breast epithelium of high-risk women, with lack of regulation of ER by estradiol, increased estrogen responsiveness as reflected by PgR expression, and a dissociation of ER expression and proliferative response.

Abstract
A patient of Wegener's granulomatosis (WG) with laryngeal involvement and respiratory difficulty has been described. Direct laryngoscopic biopsy led to the diagnosis of Wegener's granulomatosis. The patient underwent a tracheostomy and was subsequently treated with cyclophosphamide and corticosteroids to which he responded.

Abstract
Out of 50 children (100 ears) undergoing adeno-tonsillectomy, 34 ears had hearing threshold 20-50 dB (20 dB is normal) and 32 ears showed negative middle ear pressure of 100 to 400 mmH2O (100 mmH2O is normal). Post-operatively only 7 ears had hearing threshold of 20-30 dB and negative middle ear pressure of 100 to 200 mmH2O. Thus adenoidectomy improves eustachian tube functions.

Abstract
Twenty-five patients suffering from head and neck cancer and 25 healthy individuals were subjected to a blood crystallization test with 20% cupric chloride solution and the patterns were compared. In the healthy control group, the typical pattern was an eccentrically placed center of gravity with needles arranged in a radiating fashion, while in the malignant group, there was a transverse bar or transverse formation. The sensitivity of this test procedure was 88%. We therefore conclude that this study is an interesting reliable, economical and above all useful adjunctive for a mass screening programme in the diagnosis of malignant diseases of the head and neck region. The test is based purely on physical phenomena and hence should be performed under controlled physical conditions.
