Abstract
INTRODUCTION Minimally invasive tissue sampling of the brain in newborns using the Bard Monopty needle helps to diagnose various neurological conditions by obtaining relevant brain cores. We designed a modified procedure to provide maximum diagnostic utility in brain tissue biopsies. METHOD Twenty newborns underwent postmortem minimally invasive tissue sampling of the brain through the anterior fontanelle and posterior approach, using the engraved lines on the needle labeled from mark 0 to 13. The cores were correlated with conventional autopsy findings. RESULTS Meninges were best obtained at marks 0 and 1 from the anterior fontanelle and mark 1 from posterior fontenelle in 85% of cases. Periventricular brain parenchyma was best obtained from mark 3 and mark 1 from anterior and posterior fontanel, respectively in 90% cases. The sampling success in obtaining brain cores was 100%. DISCUSSION This modified technique increases the yield of meninges and brain tissue in newborns and aids in diagnosis.

Abstract
OBJECTIVE The classification of renal tumors is expanding with the addition of new molecular entities in the 5th World Health Organization classification. Apart from this, the major updates in the definition of papillary renal cell carcinoma are that these tumors are no longer subtyped into type 1 and type 2. In oncocytic tumors, the new molecularly defined renal tumors, emerging and novel entities need to be considered in the diagnosis of oncocytic and chromophobe renal tumors. MATERIAL AND METHODS This is a retrospective study to review and reclassify papillary, oncocytic, and chromophobe renal tumors based on the new WHO classification and correlate with clinical data, gross, microscopic features, and immunohistochemistry markers. RESULTS A total of thirteen cases were reviewed and the tumor grade was changed for three out of four cases of papillary renal cell carcinoma and a single case was recategorized and graded. In nine cases of oncocytic and chromophobe renal tumors, the diagnoses were modified in 3 cases. CONCLUSION Newly defined molecular renal tumors require advanced immunohistochemistry markers and molecular tests. This poses diagnostic challenges to pathologists practicing in low resource settings where molecular tests are not available.

Abstract
BACKGROUND Postmortem examination is the gold standard for establishing the cause of death. Minimally Invasive Tissue Sampling (MITS) of organs is a novel approach that can be used as an alternative to postmortem examination. In this study, the community perceptions in two states in South India towards neonatal postmortem and the acceptance towards the MITS technique is studied. METHODS In-depth interviews were conducted among the participants from Kerala and Karnataka to understand the perception towards postmortem and the acceptance of the novel MITS technique. The interviews were audio recorded, and a thematic analysis was done to identify the overarching themes and codes. RESULTS The knowledge and attitude of participants on conventional and MITS postmortem techniques, reasons for refusal, and the need for raising awareness were identified in the study. Participants favored the MITS techniques as it was less disfiguring and less time-consuming. The major concerns for refusal of conventional postmortem were that the procedure was disfiguring, time-consuming, and caused emotional stress to the parents. CONCLUSIONS Participants favored the MITS approach over conventional postmortem as it caused less disfigurement and was conducive to the religious practice of burial of the body.

Abstract
BACKGROUND ChatGPT has emerged as the most advanced and rapidly developing large language chatbot system. With its immense potential ranging from answering a simple query to cracking highly competitive medical exams, ChatGPT continues to impress the scientists and researchers worldwide giving room for more discussions regarding its utility in various fields. One such field of attention is Psychiatry. With suboptimal diagnosis and treatment, assuring mental health and well-being is a challenge in many countries, particularly developing nations. To this regard, we conducted an evaluation to assess the performance of ChatGPT 3.5 in Psychiatry using clinical cases to provide evidence-based information regarding the implication of ChatGPT 3.5 in enhancing mental health and well-being. METHODS ChatGPT 3.5 was used in this experimental study to initiate the conversations and collect responses to clinical vignettes in Psychiatry. Using 100 clinical case vignettes, the replies were assessed by expert faculties from the Department of Psychiatry. There were 100 different psychiatric illnesses represented in the cases. We recorded and assessed the initial ChatGPT 3.5 responses. The evaluation was conducted using the objective of questions that were put forth at the conclusion of the case, and the aim of the questions was divided into 10 categories. The grading was completed by taking the mean value of the scores provided by the evaluators. Graphs and tables were used to represent the grades. RESULTS The evaluation report suggests that ChatGPT 3.5 fared extremely well in Psychiatry by receiving "Grade A" ratings in 61 out of 100 cases, "Grade B" ratings in 31, and "Grade C" ratings in 8. Majority of the queries were concerned with the management strategies, which were followed by diagnosis, differential diagnosis, assessment, investigation, counselling, clinical reasoning, ethical reasoning, prognosis, and request acceptance. ChatGPT 3.5 performed extremely well, especially in generating management strategies followed by diagnoses for different psychiatric conditions. There were no responses which were graded "D" indicating that there were no errors in the diagnosis or response for clinical care. Only a few discrepancies and additional details were missed in a few responses that received a "Grade C" CONCLUSION: It is evident from our study that ChatGPT 3.5 has appreciable knowledge and interpretation skills in Psychiatry. Thus, ChatGPT 3.5 undoubtedly has the potential to transform the field of Medicine and we emphasize its utility in Psychiatry through the finding of our study. However, for any AI model to be successful, assuring the reliability, validation of information, proper guidelines and implementation framework are necessary.

Abstract
The lack of accountability is considered to be a major cause of the crisis in health care in India. Physicians as key stakeholders in the health care delivery system have traditionally been accountable for health concerns at the doctor-patient interface. Following social and organizational dynamics, the interpretations of accountability have broadened and shifted in the recent literature, expanding accountability to the community, national and global levels and to social domains. The objective of this study is to provide a comprehensive framework of accountability in medical practice that can be used as a vehicle for further contextualized research and policy input. Through literature review, this paper is presented in two parts. First, a description of accountability of a physician inclusive of the social domains is extracted by posing three pertinent questions: who is accountable? accountability to whom? and accountability for what? which addresses the roles, relationships with other stakeholders and domains of accountability. Second, a framework of accountability of a physician is designed and presented to illustrate the professional and social domains. This study revealed a shift from individual physician's accountability to collective accountability involving multiple stakeholders through complex reciprocal and multi-layered mechanisms inclusive of the social dimensions. We propose a comprehensive framework of accountability of the physician to include the social domains that its multidimensional and integrative of all stakeholders. Furthermore, we discuss the utility of the framework in the Indian health care system and how this can facilitate further research in understanding the social dimensions of all stakeholders.

Abstract
Difficulties faced in life can affect marital relationships and such troubles may be dealt with in a multitude of ways, including coping religiously. The present study examined how religious coping, either in a positive or negative manner, may have an impact on marital satisfaction. Importantly, this association was studied dyadically in a sample of religiously diverse (Buddhists, 32.3%; Taoists, 17.6%; protestant Christians, 14.1%; and others who did not identify with a specific religion, 19.1%), married older Singaporean adults (N = 1928; 964 couples). Using actor-partner interdependence modeling, we found significant actor, partner, and combined actor-partner effects for positive and negative religious coping on marital satisfaction. Specifically, marital satisfaction was highest when both spouses reported high levels of positive religious coping and low levels of negative religious coping. Taken together, these findings suggest that it is the simultaneous act of either greater positive or lower negative religious coping by both spouses that is related to higher marital satisfaction.

Abstract
Diabetic retinopathy (DR) is associated with retinal neovascularization, hard exudates, inflammation, oxidative stress and cell death, leading to vision loss. Anti-vascular endothelial growth factor (Anti-VEGF) therapy through repeated intravitreal injections is an established treatment for reducing VEGF levels in the retina for inhibiting neovascularization and leakage of hard exudates to prevent vision loss. Although anti-VEGF therapy has several clinical benefits, its monthly injection potentially causes devastating ocular complications, including trauma, intraocular hemorrhage, retinal detachment, endophthalmitis, etc. Methods: As mesenchymal stem cells (MSCs) and MSC-derived extracellular vesicles (MSC-EVs) demonstrated safety in clinical studies, we have tested the efficacy of MSC-derived small EVs (MSC-sEVs) loaded anti-VEGF drug bevacizumab in a rat model of DR. Results: The study identified a clinically significant finding that sEV loaded with bevacizumab reduces the frequency of intravitreal injection required for treating diabetic retinopathy. The sustained effect is observed from the reduced levels of VEGF, exudates and leukostasis for more than two months following intravitreal injection of sEV loaded with bevacizumab, while bevacizumab alone could maintain reduced levels for about one month. Furthermore, retinal cell death was consistently lower in this period than only bevacizumab. Conclusion: This study provided significant evidence for the prolonged benefits of sEVs as a drug delivery system. Also, EV-mediated drug delivery systems could be considered for clinical application of retinal diseases as they maintain vitreous clarity in the light path due to their composition being similar to cells.

Abstract
Discoveries in the last few years have emphasized the existence of an enormous breadth of communication between osteo-immune systems. These discoveries fuel novel approaches for the treatment of several bone pathologies including osteoporosis. Bifidobacterium longum (BL) is a preferred probiotic of choice due to its varied immunomodulatory potential in alleviating various inflammatory diseases. Here, we evaluate the effect of BL in an ovariectomy (ovx)-induced post-menopausal osteoporotic mouse model. Our in vitro findings reveal that BL suppresses the differentiation and functional activity of RANKL-induced osteoclastogenesis in both mouse bone marrow cells and human PBMCs. Strikingly, BL-induced Bregs were found to be significantly more efficient in suppressing osteoclastogenesis and modulating Treg–Th17 cell balance with respect to control Bregs in vitro. Our in vivo µCT and bone mechanical strength data further confirm that BL supplementation significantly enhanced bone mass and bone strength, along with improving the bone microarchitecture in ovx mice. Remarkably, alterations in frequencies of CD19+CD1dhiCD5+IL-10+ Bregs, CD4+Foxp3+IL-10+ Tregs, and CD4+Rorγt+IL-17+ Th17 cells in distinct lymphoid organs along with serum-cytokine data (enhanced anti-osteoclastogenic cytokines IFN-γ and IL-10 and reduced osteoclastogenic-cytokines IL-6, IL-17, and TNF-α) strongly support the immunomodulatory potential of BL. Altogether, our findings establish a novel osteo-protective and immunomodulatory potential of BL in augmenting bone health under osteoporotic conditions.

Abstract
Although medical mistrust (MM) may be an impediment to public health interventions, no MM scale has been validated across countries and the assessment of MM has not been explored using item response theory, which allows generalisation beyond the sampled data. We aimed to determine the dimensionality of a brief MM measure across four countries through Mokken analysis and Graded Response Modelling. Analysis of 1468 participants from UK (n = 1179), Ireland (n = 191), India (n = 49) and Malaysia (n = 49) demonstrated that MM items formed a hierarchical, unidimensional measure, which is very informative about high levels of MM. Possible item reduction and scoring changes were also demonstrated. This study demonstrates that this brief MM measure is suitable for international studies as it is unidimensional across countries, cross cultural, and shows that minor adjustments will not impact on the assessment of MM when using these items.

Abstract
Background Minimally invasive tissue sampling (MITS) of organs has been used as an alternative to complete diagnostic autopsy in countries where refusal for autopsy in newborns is common for sociocultural reasons. There is a paucity of literature regarding the diagnostic utility of MITS of the brain after death in neonates with neurological insults, especially in India. Methods This was a prospective, preliminary single-center tertiary care hospital study in India, focused specifically on MITS of the brain after neonatal death as a diagnostic tool to identify the various neurological insults. All neonatal deaths with neurological symptoms occurring within the first 30 days of life were enrolled, irrespective of the suspected clinical diagnosis. Results Sixteen neonates were enrolled after death for MITS of the brain, performed for diagnostic purposes, during the study period from February 2020 to March 2021. Their gestational ages ranged from 26 to 38 weeks. All neonates had either a history of seizures and/or respiratory distress or clinical evidence of sepsis and were on ventilator support. Histopathology in all 16 neonates showed evidence of anoxia, with or without reactive astrogliosis or microgliosis. In 5 neonates with cranial ultrasound evidence of brain hemorrhage, MITS of the brain showed intraventricular hemorrhage, subdural hemorrhage, or intraparenchymal white matter microhemorrhages. Premortem blood culture–proven sepsis was seen in 9 neonates. In all cases (100%), MITS had a good diagnostic yield and was useful to establish the neurological insult in the brain. Conclusions MITS of the brain provides an accurate and adequate diagnosis and can be an alternative to complete diagnostic autopsy for establishing the cause of death due to neurological insults, especially in low-resource settings where obtaining consent for more invasive procedure is often challenging.

Abstract
BACKGROUND AND OBJECTIVE The modulatory role of prolactin in autoimmune regulation is well established. Hyperprolactinemia is often associated with autoimmune disease like systemic lupus erythematosus and autoimmune thyroid diseases. The objective was to compare levels of direct and indirect autoimmune factors in different categories of hyperprolactinemia cases and predict the direction of association between hyperprolactinemia and autoimmune factors, if any. METHODS A total of 102 hyperprolactinemia cases (>100 ng/mL serum prolactin level) were included along with 24 controls. Among 102 hyperprolactinemia cases, there were 36 idiopathic cases, 19 pituitary adenoma cases, 36 drug-induced cases, and 11 cases associated with other secondary/systemic diseases (chronic renal failure, chronic hepatic failure, etc). MEASUREMENTS Direct autoimmune markers, IL-2, IFN-γ, IL-4, and IL-5, were measured in serum by ELISA. Indirect autoimmune markers, anti-TPO, anti-tg, anti-CCP, VDRL, platelet count, and aPTT, were measured as per laboratory-defined protocol. RESULTS Serum levels of IL-4 and anti-TPO were significantly high in idiopathic hyperprolactinemia cases. Serum IL-4 levels were also significantly high in pituitary adenoma cases, drug-induced cases, and in cases with other secondary causes of hyperprolactinemia. Serum anti-TPO levels were also significantly high in drug-induced hyperprolactinemia cases. CONCLUSION No significant difference in autoimmune factors is observed between macroprolactinemia and true hyperprolactinemia. Serum IL-4 and anti-TPO were high in all categories of hyperprolactinemia. This suggests a possible association of hyperprolactinemia with autoimmune conditions (high IL-4 and anti-TPO), mostly subclinical. Thus, hyperprolactinemia case with serum prolactin level >100 ng/mL may require long-term follow-up for the development of autoimmune disease in future.

Abstract
Introduction: The spectrum of myofibroblastic lesions of the oral cavity ranges from reactive to benign to malignant lesions with overlapping histopathologic and immunohistologic characteristics posing a diagnostic dilemma. Observation: A 30-year-old male presented with a spontaneous swelling over the right lower buccal gingiva giving a clinical suspicion of a benign mesenchymal tumor. The lesion presented with a varied biphasic microscopic appearance that posed as a challenge for diagnosis. Commentaries: The incisional biopsy of the lesion showed a highly collagenous stroma with spindle-shaped cells, while the excision biopsy revealed myxoid and hyalinized stroma. A panel of markers comprising of SMA (smooth muscle actin). CD-34, β-Catenin, and Alcian blue stain was employed to arrive at a diagnosis. Conclusion: Most myofibroblastic lesions present with diverse histological appearance which warrants a thorough assessment of the cellular and stromal components for an accurate diagnosis.

Abstract
Studies conducted by the University of Haifa, Israel in 2001, evaluating the effectiveness of bioethics being taught in medical colleges, suggested that there was a significant lack of translation in clinical care. Analysis also revealed, ineffectiveness with the teaching methodology used, lack of longitudinal integration of bioethics into the undergraduate medical curriculum, and the limited exposure to the technology in decision making when confronting ethical dilemmas. A modern novel bioethics curriculum and innovative methodology for teaching bioethics for the medical course was developed by the UNESCO Chair in Bioethics, Haifa. The horizontal (subject-wise) curriculum was vertically integrated seamlessly through the entire course. An innovative bioethics teaching methodology was employed to implement the curriculum. This new curriculum was piloted in a few medical colleges in India from 2011 to 2015 and the outcomes were evaluated. The evaluation confirmed gains over the earlier identified translation gap with added high student acceptability and satisfaction. This integrated curriculum is now formally implemented in the Indian program's Health Science Universities which is affiliated with over 200 medical schools in India. This article offers insights from the evaluated novel integrated bioethics curriculum and the innovative bioethics teaching methodology that was used in the pilot program.

Abstract
Worldwide, there is a rise in the incidence of dengue infection associated with multiple serotypes. Epidemiological studies have reported a higher incidence of severe dengue in secondary dengue infections. A rapid fall in platelet count associated with an increase in hematocrit above the baseline is one of the warning signs of plasma leakage. This study was undertaken to determine the utility of platelet indices such as mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit in dengue fever cases with thrombocytopenia. A hospital-based cross-sectional study was carried out between April and September 2014, among dengue patients with thrombocytopenia using platelet histograms. The study population included all the laboratory confirmed cases of dengue infection with thrombocytopenia admitted at Kasturba Medical College, Manipal, Karnataka during the study period. The blood samples collected from serologically confirmed dengue patients with thrombocytopenia were analyzed using automated analyzer within 2 h of venipuncture. The platelet histograms (MPV, PDW, Plateletcrit) generated by the Beckman Coulter counter LH755™ and LH780™ series were assessed in dengue fever cases with thrombocytopenia. The mean platelet volume (MPV) was observed to be 9.01 fL (SD = 0.09). The mean platelet distribution width and median plateletcrit were 17.2% (SD = 0.98) and 0.47 (IQR 0.2-0.8) respectively. None of the study participants presented with bleeding manifestations. The present study revealed no significant changes of platelet parameters in dengue cases with thrombocytopenia.

Abstract
The association of malignancy and glomerulonephritis may be missed, especially in elderly patients. Here, we report a case of eosinophilic variant of renal cell carcinoma and renal parenchymal malakoplakia discovered on renal biopsy in a patient with steroid-dependent nephrotic syndrome. The presence of malakoplakia in our biopsy was probably due to systemic steroid therapy for glomerulonephritis, presence of concomitant asymptomatic urinary tract infection, and/or history of diabetes mellitus. The patient had remission of proteinuria following laparoscopic removal of the tumor, indicating probable remission of glomerulonephritis.

Abstract
The adult population above the age of 60 years has significantly increased in India, with a life expectancy of 68.4 years in 2016. Data regarding the renal histopathology in these patients are scarce though the number of native kidney biopsies done in this subset of population is increasing. The present study is a retrospective analysis of 231 biopsies from a total of 700 biopsies, from patients above 60 years of age (M = 65.8%; F = 34.2%) with a mean age of 64 ± 6.03 years. The indications for kidney biopsy included nephrotic syndrome (NS) (30.4%), nephritic syndrome (19.1%), rapidly progressive renal failure (11.7%), acute kidney injury (AKI) (15.7%), and acute worsening of preexisting chronic kidney disease (CKD) (23%). The median percentage of glomerulosclerosis was 22% (5%–45%), and interstitial fibrosis and tubular atrophy was 30% (10%–50%). The most common cause for nephrotic syndrome was membranous nephropathy (31.4%) and for nephritic syndrome was benign arterionephrosclerosis (22.7%). Postinfectious glomerulonephritis (29.6%) was the leading cause for rapidly progressive renal failure. Acute injury on CKD was notable in patients with diabetic nephropathy (30.2%). The predominant causes for AKI were acute tubulointerstitial nephritis (33.3%), acute tubular necrosis (22.2%), and acute pyelonephritis (19.4%). The biopsy proven histopathological features enabled us in tailoring the therapy. None of the patients developed life-threatening complications following ultrasonography-guided biopsy.

Abstract
Pycnodysostosis is an autosomal recessive skeletal dysplasia caused by pathogenic variants in the cathepsin K ( CTSK ) gene. We report seven patients from four unrelated families with this condition in whom we have identified three novel pathogenic variants, c.120 + 1G > T in intron 2, c.399 + 1G > A in intron 4, and c.148T > G (p.W50G) in exon 2, and a known variant, c.568C > T (p.Q190*) in exon 5 of CTSK . We present the clinical, radiographic, and molecular findings of all individuals with molecularly proven pycnodysostosis from the present cohort. We also report the occurrence of giant cell tumor in the skull of a patient with this condition.

Abstract
We report on a consanguineous family with three pregnancies affected with Fraser syndrome. We note severe brachydactyly is a manifestation of Fraser syndrome and found a novel homozygous splice site variation c.3293-2A>T in FRAS1. We would like to highlight variable manifestations of Fraser syndrome and the presence of oligohydramnios in the antenatal period often makes prenatal diagnosis clinically challenging.

Abstract
A growing number of individuals with autism spectrum disorder are aging into adulthood. In the United States, Medicaid is the primary payer for services for adults with autism spectrum disorder, yet there are few funded programs that provide dedicated supports to this population. This study examined the experiences of adults with autism spectrum disorder in two Medicaid-funded programs in Pennsylvania through focus groups. Researchers conducted 20 focus groups with a total of 36 adults with autism spectrum disorder, 32 family members, 32 direct care staff, and 20 program administrators. Using thematic analysis, we identified three themes: training needs, community engagement and socialization, and employment. There was a need for additional training to meet the varying needs of program participants including co-occurring diagnoses, sexuality, and long-term planning. Adults with autism spectrum disorder prioritized more individualized community activities based on their interests. Finally, barriers to and strategies for successful employment were discussed. It will be crucial for policy makers to utilize the findings to inform program improvement and development based on the experiences of individuals impacted by these services and systems directly. Additionally, researchers should use the findings from this study to design interventions for adults with autism spectrum disorder as it includes their voices.

Abstract
Understanding technology evolution through periodic landscaping is an important stage of strategic planning in R&D management. In fields like that of healthcare, where initial R&D investment is huge and good medical products serve patients better, activities of periodic landscaping become crucial for planning. Approximately 5% of the world’s population has hearing disabilities. Current hearing aid products meet less than 10% of the global needs. Patent data and classifications on cochlear implants from 1977–2010 show the technology evolution in the area of such an implant. We attempt to highlight emergence and disappearance of patent classes over a period of time indicating changes in growth of cochlear implant technologies. Using network analysis technique we explore and capture the technology evolution in patent classes by showing what emerged or disappeared over time. Dominant classes are identified. The sporadic influence of university research in cochlear implants is also discussed.

Abstract
BACKGROUND Cervical cancer is the second commonest cancer among Indian women and its association with human papilloma virus (HPV) is well established. This preventable cancer accounts for the maximum number of cancer related deaths among rural Indian women. Unlike in developed countries there are no organized cervical cancer screening programmes in India due to lack of resources and manpower. OBJECTIVE To detect genital HPV infection using urine samples among asymptomatic rural women in the age group of 18-65 years. MATERIALS AND METHODS The study area chosen was Perdoor village in Udupi Taluk, Karnataka State and all the women in the age group of 18-65 years formed the study cohort. A cross sectional study was conducted by house visits and 1,305 women were enrolled in the study. After taking written informed consent a data sheet was filled and early stream random urine samples were collected, transported to a laboratory at 4OC and aliquoted. Samples were tested using nested HPV PCR with PGMY09/11 and GP5+/6+ primers. Positive cases were genotyped by sequence analysis. RESULTS Study participants included 1,134 sexually active and 171 unmarried women with a mean age at marriage of 22.1 (SD=3.9) years. Study area showed high female literacy rate of 86.6%. Five urine samples tested positive for HPV DNA (0.4%). CONCLUSIONS We found very low genital HPV infection rate among women from monogamous community. This is the first major population based study carried out among asymptomatic rural women to detect genital HPV infectio from Karnataka using urine samples.

Abstract
BACKGROUND The EAU guidelines on non-muscle-invasive bladder cancer (NMIBC) provide for risk stratification in low, intermediate and high risk based on infiltration depth, grading, concomitant carcinoma in situ, recurrence status, focality and tumour size. The aim of this study was to evaluate guideline adherence regarding risk stratification and risk-adapted treatment recommendations in NMIBC. MATERIAL AND METHODS An email-based survey distributed over the urological professional associations of Berlin, Brandenburg, Bremen, Hamburg, Mecklenburg-Western-Pomerania, Lower Saxony and Schleswig-Holstein assessed field of activity (doctor's office vs. clinic) and the presence of the additional qualification "Medical Tumour Therapy" (aqMtt). Also it inquired about the tools used for risk stratification in NMIBC. Finally, 3 scenarios were given, 2 of them corresponding to high-risk NMIBC and one corresponding to intermediate-risk NMIBC. Respondents were asked to provide a treatment recommendation. The results were presented comparatively for field of activity (doctor's office vs. clinic) and presence of aqMtt. RESULTS 74 responses were received (response rate of 12.3%). 57 (77.0%) of respondents had aqMtt. 52 (70.3%) worked in doctor's offices or medical care centres, 12 (16.2%) in a urology clinic, and for 10 (13.5%) respondents this information was lacking. The most frequently used tool for risk stratification was the EAU guideline. Accordingly, treatment recommendations for the three scenarios were considered to be correct if according to EAU guideline. In high-risk NMIBC, an average 29.3% (19.3-37.5%) of adequate treatment recommendations were made depending on the comparison group. An average of 69.8% (62.5-77.2%) and 0.9% (0.0-3.9%) treatment recommendations would lead to under- or overtreatment, respectively. The corresponding values for intermediate-risk NMIBC were 56.8% (52.6-62.5%) for adequate treatment, 43.2% (37.5-47.4%) for undertreatment and 0.0% for overtreatment. Field of activity and the presence of aqMtt had no significant impact on the accuracy of treatment recommendations. CONCLUSION The results of our survey provide strong evidence of poor guideline adherence with a consecutive risk for undertreatment of patients with NMIBC. This requires joint efforts of all those involved in the treatment of NMIBC to improve quality of care.

Abstract
Squamous papilloma is the most common benign oral epithelial lesion, and it is well known to be associated with human papilloma virus 6 and 11. Here, we report a case of squamous papilloma associated with human papilloma viruses (HPV)-32 in a 4-year-old boy who presented with a verrucous lesion on the lower lip. HPV-32 is often associated with a rare benign condition focal epithelial hyperplasia (FEH). A limited number of lesions and the absence of characteristic histology ruled out FEH in our patient. To the best of our knowledge, the association of oral squamous papilloma with HPV-32 is hitherto unreported.

Abstract
Tuberculosis caused by Mycobacterium tuberculosis presents a major health challenge in endemic countries and spares no organ in the human body. This infection is a mimicker of various disease processes such as metastasis, lymphoproliferative diseases, and other granulomatous conditions such as sarcoidosis and fungal infections. The most challenging and important differential is metastasis, especially in the disseminated form of tuberculosis. We present a histopathologically proven case of isolated hepatosplenic tuberculosis that was provisionally diagnosed as lymphoma due to its unusual, restricted involvement of the liver and spleen.

Abstract
In recent years, business practitioners are seen valuing patents on the basis of the market price that the patent can attract. Researchers have also looked into various patent latent variables and firm variables that influence the price of a patent. Forward citations of a patent are shown to play a role in determining price. Using patent auction price data (of Ocean Tomo now ICAP patent brokerage), we delve deeper into the role of forward citations. The successfully sold 167 singleton patents form the sample of our study. We found that, it is mainly the right tail of the citation distribution that explains the high prices of the patents falling on the right tail of the price distribution. There is consistency in the literature on the positive correlation between patent prices and forward citations. In this paper, we go deeper to understand this linear relationship through case studies. Case studies of patents with high and low citations are described in this paper to understand why some patents attracted high prices. We look into the role of additional patent latent variables like age, technology discipline, class and breadth of the patent in influencing citations that a patent receives.

Abstract
INTRODUCTION Primary small cell carcinoma of the esophagus is a rare and aggressive tumor. Patients present with metastatic disease and have a poor clinical outcome. The objective of the study was to correlate clinical and histopathological features of primary small cell carcinoma of the esophagus diagnosed and treated at our hospital. MATERIALS AND METHODS A retrospective study of 11 patients diagnosed with primary small cell carcinoma of the esophagus in Kasturba Hospital, Manipal between 2006 and 2014 was done. The histopathological and immunohistochemical features were correlated with clinical and endoscopic findings. RESULTS Eleven patients were diagnosed to have small cell carcinoma of esophagus with a male preponderance. Common presenting symptoms were dysphagia and weight loss. Majority of the patients showed mid esophageal ulceroproliferative growth. Biopsy findings were consistent with the characteristic morphology of small cell carcinoma and demonstrated immunoreactivity to neuroendocrine markers. In addition, few cases also showed adjacent squamous dysplasia/carcinoma. Most of the patients presented with metastatic disease, liver being the most common site. These patients were treated by chemotherapy and radiotherapy. CONCLUSION Esophageal small cell carcinomas are aggressive tumors with high rates of distant metastasis. Presence of squamous dysplasia /squamous cell carcinoma in the adjacent mucosa supports the hypothesis that this neoplasm arise from pleuripotent stem cells. Presence of the latter is also useful to rule out spread from lung primary.

Abstract
Diagnosis of adnexal torsion can be difficult, especially during pregnancy. Delay in diagnosis can lead to necrosis and loss of the affected ovary compromising the reproductive capacity, especially in young women. A 22-year-old primigravida presented to the emergency room at 10 weeks of gestation with acute onset left iliac fossa pain. Ultrasound examination showed a live intra-uterine gestation of 10 weeks, enlarged and edematous left ovary with a clear cyst of 76 mm × 63 mm with flow to the ovary. She underwent emergency surgery with a provisional diagnosis of torsion of left adnexa. Mini-laparotomy, detorsion of the twisted adnexa and ovarian cystectomy with reconstruction was performed thus conserving the tube and ovary. The pregnancy progressed normally; follow-up ultrasound scans showed normal functioning ovaries. Clinical appearance of torted adnexa does not correlate well with the residual function. Ovarian function can be preserved by untwisting, even if ovary appears necrotic.
