Impact of artificial intelligence on the diagnosis, treatment and prognosis of endometrial cancer.

Endometrial cancer is one of the most prevalent tumours in females and holds an 83% survival rate within 5 years of diagnosis. Hypoestrogenism is a major risk factor for the development of endometrial carcinoma (EC) therefore two major types are derived, type 1 being oestrogen-dependent and type 2 being oestrogen independent. Surgery, chemotherapeutic drugs, and radiation therapy are only a few of the treatment options for EC. Treatment of gynaecologic malignancies greatly depends on diagnosis or prognostic prediction. Diagnostic imaging data and clinical course prediction are the two core pillars of artificial intelligence (AI) applications. One of the most popular imaging techniques for spotting preoperative endometrial cancer is MRI, although this technique can only produce qualitative data. When used to classify patients, AI improves the effectiveness of visual feature extraction. In general, AI has the potential to enhance the precision and effectiveness of endometrial cancer diagnosis and therapy. This review aims to highlight the current status of applications of AI in endometrial cancer and provide a comprehensive understanding of how recent advancements in AI have assisted clinicians in making better diagnosis and improving prognosis of endometrial cancer. Still, additional study is required to comprehend its strengths and limits fully.

Efficacy of Individualized Homeopathic Medicines in the Treatment of Sciatica Pain: Double-Blind, Randomized, Placebo-Controlled Trial.

Objectives: Sciatica is a debilitating condition that causes pain in its distribution or in the lumbosacral nerve root that is connected to it. Although there are claims that homeopathy can reduce sciatica pain, systematic scientific proof is currently lacking. The objective of the trial was to determine whether individualized homeopathic medicines (IHMs) were as effective as identical-looking placebos in treating sciatica pain. Design: This is a double-blind, randomized (1:1), two parallel arms, placebo-controlled trial. Setting: The study was conducted at Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, Howrah, West Bengal, India. Subjects: Sixty participants with sciatica pain were included in this study. Interventions: Verum (n = 30; IHMs plus concomitant care) versus control (n = 30; placebos plus concomitant care). Outcome measures: Primary-Sciatica Bothersome Index (SBI) and Sciatica Frequency Index (SFI) scores and secondary-Roland Morris Pain and Disability Questionnaire (RMPDQ), Short Form McGill Pain Questionnaire (SF-MPQ), and Oswestry Low Back Pain Questionnaire (OLBPQ) scores: all of them were measured at baseline, and every month, up to 3 months. Results: Intention-to-treat sample (n = 60) was analyzed. Group differences were examined by two-way (split-half) repeated measure analysis of variance, primarily accounting for between groups and time interactions, and additionally, by unpaired t tests comparing the estimates obtained individually every month. The level of significance was set at p < 0.025 and <0.05 two tailed for the primary and secondary outcomes, respectively. Group differences could not achieve significance in SBI (p = 0.044), SFI (p = 0.080), and RMPDQ scores (p = 0.134), but were significant for SF-MPQ (p = 0.007) and OLBPQ (p = 0.036). Gnaphalium polycephalum (n = 6; 10%) was the most frequently prescribed medicine. No harm, serious adverse events, or intercurrent illnesses were recorded in either of the groups. Conclusions: The primary outcome failed to demonstrate evidently that homeopathy was effective beyond placebo, and the trial remained inconclusive. Independent replications are warranted to confirm the findings. Clinical Trial Registration Number: CTRI/2020/10/028617.

Interobserver Variability in Semen Analysis: Findings From a Quality Control Initiative.

Introduction For laboratory tests, precision and accuracy are indispensable to ensure reliable results for both clinical diagnosis and research endeavors. The accuracy and reliability of results are important because they have an impact on both patient management and research. In this study, we evaluated the inter-observer variability between a trained technician and two academic residents, which acted both as a quality control measure as well as an assessment of training outcomes. Material and methods Freshly obtained semen samples from 28 subjects coming to the andrology laboratory were used. Semen analysis was performed by a regular technician permanently posted in the laboratory and two residents on completion of their posting in the andrology laboratory. All three examined the same sample after liquefaction for assessment of sperm motility, sperm concentration, sperm vitality, and sperm morphology. Semen analysis was done as per the recommendations of the WHO. Results The results of the study are presented as a coefficient of variation (CV), S charts, and Bland-Altman plot where we evaluated the interobserver variability in parameters on semen analysis of the same sample by three different assessors. The mean CV for sperm concentration across the samples was 6.24%. For sperm vitality, sperm morphology, and sperm motility the mean CV was 10.14%, 2.66%, and 8.11%, respectively. The S chart and Bland-Altman plot found a few random errors in measurements. Conclusion Regular quality control assessments are essential and should be implemented in andrology laboratories to ensure accurate and reliable results. Proper training of laboratory personnel is also vital for consistent outcomes. Other measures such as equipment calibration, use of high-quality reagents, and standard reporting are also crucial for the best results from a laboratory.

The Effect of Age on Semen Quality Among Male Partners of Infertile Couples: An Observational Study in a Tertiary Care Center in Eastern India.

INTRODUCTION: Male infertility contributes to a significant proportion of infertility cases, and advanced paternal age has been suggested to affect semen quality and fertility. However, the relationship between age and semen quality remains inconclusive, with conflicting findings reported in the literature. This study aimed to investigate the effect of age on semen quality among male partners of infertile couples in a tertiary care center in eastern India. METHODS: A cross-sectional observational study was conducted, involving 390 male participants aged 21-50 years, who were referred to the andrology laboratory for semen analysis between January 2019 and December 2022. Participants were categorized into three age groups (21-30, 31-40, and 41-50 years). Semen parameters, including sperm concentration, semen volume, motility, and morphology, were assessed according to the World Health Organization guidelines. RESULTS: Among the participants, no significant differences were observed in semen volume, motility, and morphology across different age groups. However, a statistically significant difference in sperm concentration among the three age groups was observed (p = 0.022). Spearman correlation analysis revealed a positive correlation between age and sperm concentration (r = 0.124, p = 0.013) as well as total sperm count (r = 0.10, p = 0.049). CONCLUSION: In this study, no significant decline in semen quality with age was found among male partners of infertile couples aged 21-50 years. These findings highlight the complex relationship between age and semen quality and emphasize the need for further research to better understand the underlying mechanisms and provide more conclusive evidence regarding the impact of age on male fertility.

Cardiovascular implications of hypertensive autosomal dominant polycystic kidney disease: a systematic review and meta-analysis.

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is among the most common inherited kidney diseases. Hypertension is a frequent cardiovascular manifestation, especially in adults, but elevated blood pressure is also found in children and adolescents. Acknowledgment of pediatric hypertension early is critical, as it can result in serious complications long-term if left undiagnosed. OBJECTIVE: We aim to identify the influence of hypertension on cardiovascular outcomes, mainly left ventricular hypertrophy, carotid intima media thickness, and pulse wave velocity. METHODS: We performed an extensive search on Medline, Embase, CINAHL, and Web of Science databases through March 2021. Original studies with a mix of retrospective, prospective, case-control studies, cross sectional studies, and observational studies were included in the review. There was no restriction on age group. RESULTS: The preliminary search yielded 545 articles with 15 articles included after inclusion and exclusion criteria. In this meta-analysis, LVMI (SMD: 3.47 (95% CI: 0.53-6.41)) and PWV (SMD: 1.72 (95% CI: 0.08-3.36)) were found to be significantly higher in adults with ADPKD compared to non-ADPKD; however, CIMT was not found to be significantly different. Also, LVMI was observed to be significantly higher among hypertensive adults with ADPKD (n = 56) as compared to adults without ADPKD (SMD: 1.43 (95% CI: 1.08-1.79)). Fewer pediatric studies were available with heterogeneity among patient populations and results. CONCLUSIONS: Adult patients with ADPKD were found to have worse indicators of cardiovascular outcomes, including LVMI and PWV, as compared to non-ADPKD. This study demonstrates the importance of identifying and managing hypertension, especially early, in this population. Further research, particularly in younger patients, is necessary to further elucidate the relationship between hypertension in patients with ADPKD and cardiovascular disease.

Efficacy and safety of colchicine for the treatment of osteoarthritis: a systematic review and meta-analysis of intervention trials.

OBJECTIVE: Colchicine, an approved treatment for gout, has been trialed in many diseases including osteoarthritis (OA) due to its anti-inflammatory effects. However, its efficacy and safety remain unclear in OA. This systematic review and meta-analysis evaluated the efficacy and safety of colchicine for the treatment of OA. METHODS: PubMed, Web of Science, Scopus, and Cochrane Central were searched from inception through September 2022. Two reviewers independently screened for randomized controlled trials (RCTs) comparing colchicine with placebo or other active comparators for the treatment of OA (knee, hand, or hip OA), extracted data, and performed Cochrane risk of bias assessments. RESULT: Nine RCTs for the knee OA and one for the hand OA were identified, consisting of 847 patients (429 in colchicine arms, 409 in control arms). The studies were conducted between 2002 and 2021 with follow-up periods ranging from 2 to 12 months, in India, Iran, Turkey, Australia, Singapore, and Iraq. Moderate-quality evidence showed no clinically important pain reduction with colchicine compared to control (standardized mean difference [SMD], 0.17; 95% confidence interval [CI], - 0.55, 0.22). Moderate-quality evidence showed no improvement in function with colchicine compared to control in knee OA patients (SMD, - 0.37; 95% CI, - 0.87, 0.13). Colchicine showed an acceptable safety profile with AEs/SAEs comparable to control. CONCLUSION: Current evidence does not suggest a benefit of colchicine in reducing pain and improving physical function in the overall cohort of hand/knee OA patients. Future trials should focus on the subgroups of OA patients with local or systemic inflammation and/or mineralization who might benefit from colchicine.

Effects of the COVID-19 pandemic on semen quality in male partners of infertile couples: a hospital-based observational study.

The effects of the coronavirus disease 2019 (COVID-19) pandemic on male fertility have received considerable attention because human testes contain high levels of angiotensin-converting enzyme-2 receptors, through which severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can enter. Early studies showed decreases in semen quality during and after recovery from COVID-19. However, no semen quality studies have examined the effects of widespread subclinical and mild disease, as well as changes in lifestyle, psychosocial behavior, intake of dietary supplements, and stress. This cross-sectional study compared semen quality parameters in male partners of infertile couples between men who underwent semen analysis before the COVID-19 pandemic (prepandemic group) and men who underwent semen analysis during the pandemic period (pandemic group); the analysis sought to clarify the overall effects of the pandemic. No participants in the pandemic group had experienced clinically overt disease. Among the 239 participants, mean body weight (P = 0.001), mean body mass index (P < 0.001), median sperm concentration (P = 0.014), total sperm count (P = 0.006), and total percentages of motile (P = 0.013) and abnormal cells (P < 0.001) were significantly greater in the pandemic group (n = 137) than those in the prepandemic group (n = 102). Among abnormal cells, the percentages of cells with excess residual cytoplasm (P < 0.001), head defects (P < 0.001), and tail defects (P = 0.015) were significantly greater in the pandemic group than those in the prepandemic group. With the exception of morphology, the overall semenogram results were better in the pandemic group than those in the prepandemic group.

Hypoxia-driven metabolic heterogeneity and immune evasive behaviour of gastrointestinal cancers: Elements of a recipe for disaster.

Gastrointestinal (GI) cancers refer to a group of malignancies associated with the GI tract (GIT). Like other solid tumors, hypoxic regions consistently feature inside the GI tumor microenvironment (TME) and contribute towards metabolic reprogramming of tumor-resident cells by modulating hypoxia-induced factors. We highlight here how the metabolic crosstalk between cancer cells and immune cells generate immunosuppressive environment inside hypoxic tumors. Given the fluctuating nature of tumor hypoxia, the metabolic fluxes between immune cells and cancer cells change dynamically. These changes alter cellular phenotypes and functions, resulting in the acceleration of cancer progression. These evolved properties of hypoxic tumors make metabolism-targeting monotherapy approaches or immunotherapy-measures unsuccessful. The current review highlights the advantages of combined immunometabolic treatment strategies to target hypoxic GI cancers and also identifies research areas to develop better combinational therapeutics for future.

Assessment of the Relationship between Oral Health Behavior, Oral Hygiene, and Gingival Status of Adolescent Tobacco Consumers in Ranchi, Jharkhand: A Comparative Study.

BACKGROUND: Tobacco consumption is very prevalent in India and associated with a number of oral health problems. Good oral health behavior plays a significant role in improving oral hygiene status. OBJECTIVES: To assess the relationship between the oral health behavior, oral hygiene, and gingival status of adolescent tobacco consumers (smoke/smokeless form) and to compare it with that of the nonconsumers of tobacco in the same age group, who were selected from the OPD of Dental Institute, RIMS. METHODS: This was a cross-sectional study carried out in Ranchi. The study included a total of 400 adolescents who were reported to be consumers of tobacco and 400 adolescents who were nonconsumers of tobacco. The oral health behavior was assessed using HU-DBI. The plaque and gingival scores were assessed using standardized indices. Data were analyzed using the Chi-square test, independent sample t-test, and Pearson's correlation. The significance level was set at p ≤ 0.05. RESULTS: The majority of tobacco consumers were found to have poor plaque scores as assessed using the plaque index. As assessed by the gingival index, the majority of the tobacco consumers were found to have a severe form of gingivitis. The mean plaque score (2.38 ± 0.51, p value <0.001) and the mean gingival score (2.6 ± 0.63, p value <0.001) were significantly higher in tobacco consumers. The mean HU-DBI score was significantly higher in non-tobacco consumers (8.3 ± 1.60, p value <0.001). It was observed that the gingival and plaque scores have a significant negative correlation with the HU-DBI score. The majority of tobacco consumers were worried about the staining of teeth and bleeding from gums. A dental visit for a routine preventive check-up was reported to be rare in both groups. CONCLUSION: The oral hygiene and gingival status were significantly poor in tobacco consumers compared to non-tobacco consumers. As the oral health behavior of the participants improved, the plaque and gingival scores reduced significantly.

Assessment of Anterior Loop of Inferior Alveolar Nerve and Its Anatomic Variations with Age, Gender, and Dentition Status in Indian Population: A CBCT Study.

BACKGROUND: The posterior region of the mandible is more often related to iatrogenic errors, but the interforaminal region is also not spared for neurovascular complications. This study aimed to use CBCT images to evaluate the prevalence of anterior nerve looping and its variations with age, gender, and dentition status. METHODS: This retrospective study was carried out by studying 600 CBCT scans retrieved from archival records of a CBCT center in Lucknow. The scans were inspected by two trained investigators. The length of the anterior loop was measured using the measuring tool of Carestream 3D imaging software. Descriptive and analytical tests were performed. RESULTS: The prevalence of the anterior loop of the inferior alveolar nerve was found to be 56%. The prevalence was found to be more on the right side (29.0%) compared to the left side (27.0%). The most common anterior looping of the inferior alveolar nerve was type 3 followed by type 1. Males were found to have significantly higher loops compared to females. The number of loops was found to decrease significantly with age. The mean length of the loop was found to vary from 1.14 to 1.61 mm. CONCLUSION: The anterior looping of IAN is very much prevalent in the Lucknow population. The use of the CBCT technique and appropriate preplanning prior to surgery or implant placement should be performed to prevent nerve injury.

Hydrazine Detection during Ammonia Electro-oxidation Using an Aggregation-Induced Emission Dye.

Ammonia electro-oxidation is an extremely significant reaction with regards to the nitrogen cycle, hydrogen economy, and wastewater remediation. The design of efficient electrocatalysts for use in the ammonia electro-oxidation reaction (AOR) requires comprehensive understanding of the mechanism and intermediates involved. In this study, aggregation-induced emission (AIE), a robust fluorescence sensing platform, is employed for the sensitive and qualitative detection of hydrazine (N2H4), one of the important intermediates during the AOR. Here, we successfully identified N2H4 as a main intermediate during the AOR on the model Pt/C electrocatalyst using 4-(1,2,2-triphenylvinyl)benzaldehyde (TPE-CHO), an aggregation-induced emission luminogen (AIEgen). We propose the AOR mechanism for Pt with N2H4 being formed during the dimerization process (NH2 coupling) within the framework of the Gerischer and Mauerer mechanism. The unique chemodosimeter approach demonstrated in this study opens a novel pathway for understanding electrochemical reactions in depth.

Metal-induced oxidative stress level in patients with fibromyalgia syndrome and its contribution to the severity of the disease: A correlational study.

BACKGROUND: Fibromyalgia syndrome (FMS) is an extra-articular rheumatological disease characterised by widespread chronic musculoskeletal pain. Metal-induced oxidative stress contributes to the severity of FMS. AIMS: First, this study evaluated the association between plasma levels of toxic heavy metals and essential metals with oxidative stress (OS) markers. Second, the OS markers and metal contents were correlated with the disease severity by assessing the Fibromyalgia Impact Questioner Revised (FIQR) and tender points (TP). METHOD: A total of 105 FMS patients and 105 healthy controls of similar age and sex were recruited. OS parameter such as lipid peroxidation (LPO), protein carbonyl group (PCG), nitric oxide (NO) and essential metals such as zinc (Zn), magnesium (Mg), manganese (Mn), copper (Cu) and toxic heavy metals such as aluminium (Al), arsenic (As), lead (Pb) were estimated. RESULTS: Levels of LPO, PCG, NO (p< 0.001) and Cu, Mn, and Al (p< 0.001), were significantly higher, and Mg (p< 0.001) and Zn (p< 0.001) were significantly lower in patients compared to controls. A positive association was observed between OS parameters, FIQR and TP with Cu, Al and Mn. A significant negative association was observed between Zn and Mg with FIQR, TP and OS parameters. CONCLUSION: Heavy metals such as Al induce OS parameters and decrease the levels of essential trace elements such as Mg and Zn, which may be responsible for the severity of FMS.

Au Nanoparticles Modified with Pt, Ru and SnO2 as Electrocatalysts for Ethanol Oxidation Reaction in Acids.

The anodic reaction in direct ethanol fuel cells (DEFCs), ethanol oxidation reaction (EOR) faces challenges, such as incomplete electrooxidation of ethanol and high cost of the most efficient electrocatalyst, Pt in acidic media at low temperature. In this study, core-shell electrocatalysts with an Au core and Pt-based shell (Au@Pt) are developed. The Au core size and Pt shell thickness play an important role in the EOR activity. The Au size of 2.8 nm and one layer of Pt provide the most optimized performance, having 6 times higher peak current density in contrast to commercial Pt/C. SnO2 as a support also enhances the EOR activity of Au@Pt by 1.73 times. Further modifying the Pt shell with Ru atoms achieve the highest EOR current density that is 15 and 2.5 times of Pt/C and Au@Pt. Our results suggest the importance of surface modification in rational design of advanced electrocatalysts.

Evaluation of incidence of mental nerve loop in Central India population using cone beam computed tomography.

CONTEXT: Anatomical literature has described the anterior loop being an extension of the mental nerve which is present anterior to the mental foramen while the caudal loop has been described as the distance between the lower border of the mental foramen and the lowest point of the mandibular canal. The knowledge and identification of the anterior and caudal loop of the mental nerve are important in surgical procedures performed around the mental foramen to avoid inadvertent damage to these vital structures resulting in postoperative complications. AIM: The present study was conducted to determine the incidence and measurement of mental nerve loop in the mandibular arches using cone beam computed tomography (CBCT). SETTINGS AND DESIGN: A total of 200 CBCT images were retrieved and inspected for the presence of the mental nerve loop. The length of the anterior loop was measured by counting the number of consecutive contiguous vertical cross sections displaying two round hypodense images. This number was multiplied by the thickness of the slices. The caudal loop was measured as the distance between the lower border of the mental foramen and the lowest point of mandibular canal. STATISTICAL ANALYSIS USED: Shapiro-Wilk test and Mann-Whitney U-test were used. P < 0.05 was considered statistically significant. RESULTS: 57.5% (n = 200 scans) presented with the anterior loop of the mental nerve with a mean length of 0.50 mm and 0.37 mm on the right side and left side, respectively. All the samples of CBCT scans taken were having caudal loop extension with a mean length of 3.53 mm. CONCLUSION: A considerable number of individuals (57.5%) in the present study presented with the anterior loop of the mental nerve. CBCT was found to be an effective imaging modality for the detection of anterior loop of the mental nerve.

Association of Vitamin D Receptor (FokI and BsmI) Gene Polymorphism with Bone Mineral Density and Their Effect on 25-Hydroxyvitamin D Level in North Indian Postmenopausal Women with Osteoporosis.

Osteoporosis is a systemic disease with a strong genetic component. Vitamin D receptor (VDR) has been suggested as a candidate gene for osteoporosis. Therefore the present study was aimed to investigate the pattern of allelic variants of VDR gene polymorphism (FokI and BsmI), its influence on vitamin D levels and bone mineral density (BMD) in North Indian postmenopausal women with osteoporosis for possible genetic association. 254 postmenopausal osteoporotic women and 254 postmenopausal non osteoporotic women were included in the study. VDR FokI and BsmI gene polymorphism gene were assessed by the PCR-RFLP method. Serum 25-hydroxyvitamin D was measured by the ELISA. BMD at the L1-L4 lumbar spine, hip, forearm and femoral neck was assessed by dual energy X-ray absorptiometry. The average BMD at spine and hip in postmenopausal women with bb and spine, hip, femoral neck and forearm with ff genotype had significantly low BMD. The frequency of ff genotype and f allele was significantly higher in postmenopausal osteoporotic women when compared with postmenopausal non osteoporotic women. However, no significant association was found between the genotypes and vitamin D levels. Our study reveals that VDR gene FokI and BsmI polymorphism is significantly associated with low bone mineral density. Therefore the ff genotype and f allele of VDR FokI gene may be used as an important risk factor for osteoporosis.

Relationship of internet addiction with depression and academic performance in Indian dental students.

BACKGROUND AND AIMS: Internet addiction (IA) has negative consequences on the mental health and affects daily activities. This study was conducted with the aim to assess the prevalence of Internet addiction among dental university students and to determine if there is any relationship of excessive Internet use with depression and academic performance among students. METHODS: This was a cross sectional study which included 384 dental students from different academic years. A questionnaire was prepared that collected information on demographic characteristics, pattern of Internet use, duration of use, and most common mode of Internet access. Internet addiction was assessed using Youngs Internet Addiction test. Depression was assessed using Becks depression inventory [BDI-1]. RESULTS: The prevalence of Internet addiction and depression was found to be 6% and 21.5% respectively. The first year students showed the highest mean Internet addiction (17.42±12.40) score. Chatting was the main purpose for Internet use. Logistic regression analysis showed that individuals who were depressed (Odds Ratio=6.00, p value<0.0001*) and scored less than 60% marks (Odds Ratio=6.71, p value<0.0001*) were more likely to be addicted to Internet. CONCLUSION: The addiction to internet has negative impact on mental health and academic performance. These high risk group students should be identified and psychological counseling should be provided.

Association of vitamin D receptor gene polymorphism (TaqI and Apa1) with bone mineral density in North Indian postmenopausal women.

Vitamin D receptor (VDR) gene has an important role as a candidate gene for the regulation of bone mass in osteoporosis. However, its association with bone mineral density (BMD) is controversial and has not been established in different ethnic populations. To enhance the understanding of VDR gene polymorphism in the context of BMD, we investigated the plausible genetic association of TaqI and ApaI polymorphism with BMD in North Indian postmenopausal women with osteoporosis.254 osteoporotic women (Age 55.82 ±â€¯6.91) and 254 postmenopausal non osteoporotic women (Age 54.76 ±â€¯6.26) were included in the study. VDR TaqI and ApaI polymorphism were determined by PCR (polymerase chain reaction) and RFLP (restriction fragment length polymorphism). BMD was assessed by dual energy X-ray absorptiometry (DXA) at the lumbar spine (L1-L4), hip, forearm and femoral neck. The average BMD with TT genotype was significantly lower at lumbar spine, hip and forearm. The Frequency of TT genotype and t allele was significantly high in osteoporotic women when compared with controls. The average BMD with Aa genotype was higher in ApaI. Furthermore, comparison of frequency distribution of genotype and allele for VDR ApaI between osteoporotic patients and controls did not show any significant difference. Our findings revealed that TaqI gene TT genotype was associated with low BMD in North Indian osteoporotic women. Moreover, TT genotype and t allele associated significantly with osteoporosis in postmenopausal women. Therefore, VDR TaqI gene is an important determinant of risk factor for osteoporosis.

Knowledge and awareness of oral cancer and impact of pictorial warnings on the willingness to quit tobacco in young tobacco consumers in India.

BACKGROUND: Oral cancer is most common cancer globally and is one of the most life-threatening conditions worldwide. AIM: To assess the knowledge and awareness of oral cancer and the impact of pictorial warnings on the willingness to quit tobacco in young tobacco consumers in India. METHODS: This cross-sectional study included 250 young tobacco consumers from Ranchi, Jharkhand. A pretested validated questionnaire was used that collected information on knowledge and awareness of oral cancer from the respondents. The responses were estimated on a three-point scale (No/Don't know/Yes). p-Value <0.05 was considered statistically significant. RESULTS: The majority of the respondents were aware of oral cancer (92.0%). Educational status was significantly associated with a good knowledge of awareness of oral cancer and its associated risk factors (p-Value <0.05). Media was identified as the main source for spreading oral cancer awareness (69.1%). The majority of the people were aware of the pictorial warnings on tobacco products (96.1%). However, the pictorial warnings seem to have a very low impact on willingness to quit tobacco by the respondents (20.0%). CONCLUSION: Alternative strategies need to be employed by the government to motivate people to quit tobacco consumption. Dental health education should be provided and educational pamphlets should be distributed to create awareness about the harmful effects of tobacco consumption.

Articular cartilage of knee and first MTP joint are the preferred sites to find double contour sign as an evidence of urate crystal deposition in asymptomatic hyperuricemic individuals.

BACKGROUND/OBJECTIVE: A cross-sectional study to determine the preferred sites of urate crystal deposition in asymptomatic hyperuricemic individuals by ultrasound. METHODS: In two years period twenty four asymptomatic hyperuricemic individuals (serum uric acid ≥7mg/dl) and fifty controls (serum uric acid <7mg/dl) with age more than 18 years were included in this study. Double contour sign was looked for at three articular cartilage sites (first metatarsophalangeal, tibiotalar and femoral condyle) whereas hyperechoic aggregates were looked for at one joint site (radiocarpal joint) and two tendon sites (patellar tendon and triceps tendon). The Chi-square test was used to compare the categorical variables and discrete variables were compared by one way analysis of variance. The p-value<0.05 was considered significant. RESULTS: Eight out of 24 asymptomatic hyperuricemic individuals had ultrasound evidence of urate crystal deposition in first metatarsophalangeal joint area followed by knee joint area which was detected in 6 patients. The detection rate of ultrasound abnormalities in asymptomatic hyperuricemic individuals was 45.8% with two joint area (knee and first metatarsophalangeal) and 50% with six sites assessment. Amongst controls, 16% were found to have these abnormal ultrasound findings. CONCLUSION: The highest predilection of urate crystal deposition in asymptomatic hyperuricemic individuals is the articular cartilage of Knee and first metatarsophalangeal joints. This explain the frequent clinical presentation of arthritis in these joint areas.
