Introduction: Brain lesions can be caused by varied etiological factors like neoplastic, infectious, inflammatory and vascular diseases. Accurate diagnosis in very important for correct neurosurgical treatment. A retrospective histopathological study of brain lesions is of utmost importance because as it can demonstrate the changes in the spectrum of brain lesions, burden of disease in the community, can reveal the possible risk factors and can suggest probable treatment methods for various neoplastic and non neoplastic brain lesions. Aim: To evaluate the incidence, age distribution, gender distribution, and histopathological spectrum of neoplastic and non neoplastic lesions of brain. Materials and Methods: This retrospective study was conducted in the Department of Pathology at Narayana Medical College, Nellore, Andhra Pradesh, India, from January 2019 to December 2021. Total 216 cases were studied. The tumours were classified under World Health Organization (WHO) classification. To test the mean difference between the groups, Independent sample t-test was done. Results: Out of 216 cases, 180 (83%) were neoplastic and 36 (17%) were non neoplastic lesions. The male: female ratio was 1.03:1. Non neoplastic lesions were common in males (22, 61.11%), while neoplastic lesions were common in females (92, 51.11%). The most common age group affected was 41-50 years (55, 25.46%). Astrocytoma (41, 22.77%) followed by meningioma (40, 22.22%) were the common neoplastic tumours and haematoma(7, 19.44%) was the most common non neoplastic lesion in adults. Common tumour in children (<18 years) was diffuse fibrillary astrocytoma (3/11, 27.27%)and chronic inflammatory pathology was the common non neoplastic lesion (2/11, 18.18%). Conclusion: Majority of cases were seen in 41-50 years age group. Astrocytoma was the common neoplastic tumour and haematoma was the common non neoplastic lesion in adults. Diffuse fibrillary astrocytoma was the common tumour and chronic inflammatory pathology was the common non neoplastic lesion in children. [ABSTRACT FROM AUTHOR]

Introduction: The infection potential of Coronavirus Disease 2019 (COVID-19) is remarkable due to its airborne transmission through droplets and aerosols. Paediatric dental needs were severely compromised during the COVID-19 lockdown period. Aim: To assess parents' attitudes and concerns towards approaching paediatric dentists during the COVID-19 pandemic. Materials and Methods: This cross-sectional study was conducted in Department of Paediatric and Preventive Dentistry at Narayana Dental College and Hospital, Nellore, Andhra Pradesh, India, from August 2021 to October 2021. The study included 200 parents to assess the attitudes and concerns towards approaching Paediatric dentists during the COVID-19 pandemic. A structured questionnaire was used through Google forms to collect from parents, information regarding precautions, mode of transmission of the virus and type of treatment option. The Chi-square test and Fischer-exact test were used to compare the parameters such as education and occupation with parents' attitude and knowledge. Results: Out of the 200 parents, 37 were males and 163 were females with mean age of the parents was 34.8 years. Out of total 200, 153 (76.5%) of the parents were worried to visit a Paediatric dentist. Only 56 (28%) of the children suffered from toothache during the pandemic. About 28 (14%) of parents believed that the virus is transmitted through the air and 70% of the parents preferred teledentistry. A 152 (76%) of them were willing to pay extra costs and 123 (61.5%) of respondents expected to treat the emergency condition alone. A statistically significant difference was not observed between different occupation in the answers given about transmission paths of a virus (p-value=0.39), extra payment (p-value=0.77), and preference of approach (p-value=0.223). Conclusion: Majority parents were worried to visit a Paediatric dentist and preferred teledentistry. They were ready to pay extra costs for the sanitisation. [ABSTRACT FROM AUTHOR]
