Assessment of Knowledge, Attitude, and Practice Regarding Oral Cancer among Dental Graduates-A Web-Based Survey.

The present study was conducted to assess the knowledge, attitude, and practice among new dental graduates across India. A web-based questionnaire was generated as a link through Google Drive which was sent to approximately 250 dental graduates using Whatsapp messenger. A total of 205 complete responses were received and analyzed. Frequency analysis was done using SPSS software version 21. Oral squamous cell carcinoma (OSCC) was identified as most common cancer by 48% of the subjects while the stage of oral cancer in which it is most often diagnosed was only responded correctly by 15.5% as advanced stage. Approximately one fourth (25.4%) of the participants performed dental examination to detect cancer routinely in all patients. Half of the study subjects were confident in detecting oral cancer, still majority (70.6%) of the subjects were interested in attending continuing education course on oral cancer in the future. This study revealed that the majority of the new dental clinicians were not having legitimate knowledge regarding oral cancer. Thus, this lacuna in knowledge and skills can be eliminated by conducting workshops and continuing education programs. This may subsequently aid to improve patient care.

Pulmonary fibrotic response to inhalation of ZnO nanoparticles and toluene co-exposure through directed flow nose only exposure chamber.

The increasing use of Zinc Oxide nanoparticles (ZnONPs) in paint industry is not supplemented with adequate toxicology data. This report focuses on the fibrogenic toxicity caused due to co-exposure of ZnONPs and toluene in male Wistar rats, exposed for 28 days, through directed flow nose only exposure chamber. The rats were grouped as air control, toluene control (200 ppm), zinc oxide control (10 mg/m(3)), low dose co-exposed (5 mg/m(3) ZnO and 200 ppm of toluene) and high dose co-exposed (10 mg/m(3) of ZnO and 200 ppm of toluene). Our study demonstrates that co-exposure of ZnONPs and toluene (as in paint industry), even at their respective permissible exposure level (5 mg/m(3) for ZnO and 200 ppm for toluene) have the potential to produce a progressive inflammatory and fibrotic response in the alveolar tissues of the lungs. We observed a significant increase in inflammatory markers in BAL fluid and elevated malondialdehyde (MDA) levels with lower levels of intracellular reduced glutathione (GSH) in lungs of rats of co-exposed group. Significant increase in the levels of pro-inflammatory mediators (IL-6, Ikßα, Cox-II, p-NF-κB) in lung tissues also indicated pulmonary damage. To best of our knowledge this is the first study which highlights the toxicity of co-exposed ZnO NPs and toluene.

Diagnostic algorithm for pathological evaluation of gliomas in a resource-constrained setting.

Introduction: Gliomas are the most common primary intracranial tumors. The current World Health Organization (WHO) classification of central nervous system tumors recommends integrated histo-molecular diagnosis of gliomas. However, molecular testing is not available in even most of the advanced centers of our country, and histopathology aided with immunohistochemistry (IHC) is still widely used for diagnosis. Immunohistochemical markers such as iso-citrate dehydrogenase1 (IDH1) and Alpha Thalassemia/Mental Retardation Syndrome X-linked (ATRX) can be reliably used for the correct diagnosis, prognosis, and treatment of gliomas. Aim: We aimed to develop a diagnostic algorithm by integrating morphology, IDH1, and ATRX status of gliomas seen in our institute for 1 year. Settings and Design: Analytical cross-sectional study. Materials and Methods: This study included 60 histopathologically confirmed cases of astrocytic (n = 51) and oligodendroglial tumors (n = 9). Clinical, radiological, and histopathological features were noted and tumor grades assigned according to the WHO recommendations. IDH1 and ATRX mutation status was evaluated using IHC. The tumors were divided into three molecular groups on the basis of their IDH1 and ATRX mutation status: (1) Group 1: IDH1 negative and ATRX positive, (2) Group 2: IDH1 positive and ATRX positive, (3) Group 3: IDH1 positive and ATRX negative. Results: The mean age of presentation was 45.0 ± 15.8 years with a male-to-female ratio of 2:1. Seizures, headache, and hemiparesis were the most common modes of presentation. The tumor subtypes studied were glioblastoma (n = 32), anaplastic astrocytoma (n = 7), diffuse astrocytoma (n = 6), oligodendroglioma (n = 6), pilocytic astrocytoma (n = 6), and anaplastic oligodendroglioma (n = 3). IDH1 mutation was present in 26 cases including anaplastic astrocytoma (n = 7), diffuse astrocytoma (n = 6), oligodendroglioma (n = 5), secondary glioblastoma (n = 5), and anaplastic oligodendroglioma (n = 3). ATRX mutation, i. e., loss of ATRX was observed in 17 cases including diffuse astrocytoma (n = 5), anaplastic astocytoma (n = 5), anaplastic oligodendroglioma (n = 3), oligodendroglioma (n = 3), and secondary glioblastoma (n = 1). All six cases of pilocytic astrocytoma were negative for IDH1 and ATRX mutation. There were 34 patients in Group 1 (IDH1- and ATRX +), nine cases in Group 2 (IDH1 + and ATRX +), and 17 patients in Group 3 (IDH1 + and ATRX-). Conclusion: Diagnosis of gliomas should be based on a detailed clinicoradiological and histopathological assessment, followed by genotypic characterization. Evaluation for IDH1and ATRX status has both diagnostic and prognostic value as it helps in differentiating gliomas from reactive gliosis, primary glioblastoma from secondary glioblastoma, and pilocytic astrocytoma (WHO grade I) from diffuse astrocytoma (WHO grade II). Tumors with IDH1 mutations have a better outcome than those with wild-type IDH. IHC can serve as a useful surrogate to conventional molecular tests in resource-constrained settings. By devising an algorithm based on morphological and IHC features, we were able to stratify gliomas into three prognostic subgroups.

Creating and sustaining a digital community of practice for quality improvement in South-East Asia during the COVID-19 pandemic.

INTRODUCTION: Ensuring quality of care in Low and Middle Income countries (LMICs) is challenging. Despite the implementation of various quality improvement (QI) initiatives in public and private sectors, the sustenance of improvements continues to be a major challenge. A team of healthcare professionals in India developed a digital community of practice (dCoP) focusing on QI which now has global footprints. METHODOLOGY: The dCoP was conceptualised as a multitiered structure and is operational online at www.nqocncop.org from August 2020 onwards. The platform hosts various activities related to the quality of care, including the development of new products, and involves different cadres of healthcare professionals from primary to tertiary care settings. The platform uses tracking indicators, including the cost of sustaining the dCoP to monitor the performance of the dCoP. RESULT: Since its launch in 2020, dCoP has conducted over 130 activities using 13 tools with 25 940 registration and 13 681 participants. From April 2021, it has expanded to countries across the South-East Asia region and currently has participants from 53 countries across five continents. It has developed 20 products in four thematic areas for a targeted audience. dCoP is supporting mentoring of healthcare professionals from five countries in the South-East Asia region in their improvement journey. Acquiring new knowledge and improvement in their daily clinical practice has been reported by 93% and 80% of participants, respectively. The dCoP and its partners have facilitated the publication of nearly 40 articles in international journals. CONCLUSION: This dCoP platform has become a repository of knowledge for healthcare professionals in the South-East Asia region. The current paper summarises the journey of this innovative dCoP in an LMIC setting for a wider global audience.

Comparative Efficacy of Cow Milk, KNO3, and Warm Saline Rinses in Treating Dentin Hypersensitivity Following Nonsurgical Periodontal Treatment: A Randomized Controlled Trial.

AIM: This study aimed to assess the desensitizing efficacy of commercially available cow milk compared to potassium nitrate (KNO3) mouthwash and warm saline rinses after nonsurgical periodontal treatment. MATERIALS AND METHODS: A randomized controlled trial was conducted in the Department of Public Health Dentistry of a dental college from August 21, 2018 to September 10, 2018. A total of 75 patients who reported hypersensitivity after scaling and root planing (SRP) were recruited and randomly assigned into three groups: cow milk (I), KNO3 mouthwash (II), and warm saline rinses (III). Dentine hypersensitivity (DH) was assessed at six time points using the verbal rating scale (VRS) for thermal stimuli and visual analog scale (VAS) for air blast and thermal stimuli. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY). Mean reduction in DH in each group was measured using non-parametric tests. RESULTS: Patients in all the three groups were found to be comparable with respect to baseline characteristics. Mean reduction in VRS and VAS scores for DH in milk and KNO3 mouthwash was found to be significantly high as compared to warm saline rinses group. CONCLUSION: From the results, cow milk was found to be equivalent in efficacy as compared with KNO3 mouthwash but superior to warm saline rinses in treating DH post-SRP.

Not just studies, but fitness can also get you the intelligence and the grades!!

OBJECTIVES: Physical fitness in children and adolescents determines their health status and predicts if they are prone to co-morbidities that may extend in adulthood. The initial literature on the benefits of being physically fit was limited to the musculoskeletal and cardio-respiratory systems. The recent trends have shown that physical fitness has an effect on the neurological system as well. Considering physical inactivity to be a problem in today's world and the growing evidences on physical fitness being related to cognition and academic performance, there is a need to explore more on these relationships. Thus, this study aims to find the correlation between physical fitness with academic performance and cognitive functions in adolescent urban school children. HYPOTHESIS: There is an association between physical fitness with academic performance and cognitive function. METHODOLOGY: Three hundred and ninteen children were approached out of which 107 children consented for assessment. Their physical fitness was measured using the Progressive Aerobic Cardiovascular Endurance Run (PACER) test, the cognitive function was assessed using the Stroop test and the academic performance were taken from their final exam grades of 2019. RESULTS: A moderate positive correlation was found between physical fitness with cognitive function (r=0.528), with academic performance (r=0.545) and with self-reported physical activity per week (r=0.427). A fair negative correlation was found between physical fitness and Body Mass Index (BMI) (r=0.296). CONCLUSION: This study confirms that physical fitness is positively associated with cognitive function, academic performance and self-reported physical activities and has a negative correlation with BMI.

Collision of Malignant Melanoma and Squamous Cell Carcinoma in Rectum: First Report of a Rare Tumor.

The term collision tumor is used to describe two neoplasms occurring in the same anatomic location with juxtaposition of different tumor elements. Such a coexistence of tumors anywhere in the body is relatively rare. We report a case of 32-year-old female with collision tumor of rectum. The tumor showed two distinct histological patterns with predominant component consisting of malignant melanoma and a minor component of squamous cell carcinoma. The morphological picture of collision was further confirmed by specific immunohistochemical profile of the two tumors. Collision tumors of rectum are uncommon with most of the reported cases comprising adenocarcinoma and neuroendocrine tumors. To the best of our knowledge this is the first case of collision tumor of malignant melanoma and squamous cell carcinoma in the rectum.

Cysticercosis masquerading as tuberculous lymphadenitis in supraclavicular region.

Cysticercosis is a parasitic infestation caused by the larvae of the tapeworm Taenia solium. In humans, cysticercosis spreads through fecal-oral route by ingesting food contaminated with eggs of pork tapeworm. The most frequent sites affected are central nervous system, eye, subcutaneous tissue, and skeletal muscle. We report a case of cysticercosis presenting as left supraclavicular swelling which is a rare site, diagnosed on fine-needle aspiration.
