RESUMEN
Background MRI is the standard tool for imaging the pituitary gland. MRI is useful in detecting pathological conditions in the pituitary. Changes in the size and shape of the pituitary among different age groups are seen in MRI. Linear growth is seen in the pituitary during puberty except for growth spurts at the 1st, 10th, and 15th years, followed by a decline in pituitary height and cross-sectional area with increasing age. A convex upper margin was seen in females more than in males. There is a shortage of information about pituitary dimensions and volume in various age groups and among both genders in the Indian population. Hence, a study is needed to assess these parameters. Materials and methods A retrospective cross-sectional study was done in the MRI unit of Radiology, Saveetha Medical College and Hospital, Chennai. A total of 200 patients in the age group of 11-80 years who underwent MRI free from neuroendocrine, neurological, and psychiatric disorders were included in this study. Statistical analysis Measurements were made of the pituitary gland's height, volume, and anteroposterior and transverse dimensions. Using SPSS Statistics software (IBM Corp. IBM SPSS Statistics for Windows. Armonk, NY: IBM Corp.), the data was input and examined. The ANOVA test revealed the relationship between anteroposterior dimension, transverse dimension, height, and volume with age. In contrast, an independent t-test determined the association of the same parameters with sex. The Chi-square test was used to assess the association of the shape of the pituitary gland with age and sex. Results Anteroposterior dimension, height, and volume of the pituitary gland were found to be statistically significant with age (p<0.05), but the transverse dimension was not significant with age (p>0.05). However, the independent t-test showed highly significant differences between the anteroposterior dimension in males and females. The shape of the pituitary gland was found to be statistically significant with age and gender. In contrast, the pituitary gland's transverse diameter, height, and volume showed no significance. Conclusion The study helps identify the substantial changes in the pituitary gland during a person's lifespan, which are affected by age and gender. The pituitary height and volume will reflect physiological neuroendocrine differences between younger and older male and female subjects.
RESUMEN
BACKGROUND: The increased use of electronic devices has caused a rise in the generation of e-waste, which is detrimental to the environment and human health. This study aimed to assess consumer awareness, perception, and disposal methods of e-waste management and its determinants in a semi-urban area of northern Tamil Nadu. MATERIALS AND METHODS: It was a mixed-method approach using a sequential explanatory technique with both quantitative and qualitative methods in adult e-consumers. Quantitative data were collected from 350 participants selected via simple random sampling using score-based semi-structured questionnaire. Qualitative data were obtained purposely from eight selected consumers such as recyclers, local leaders, and importers of electronics using key informant interviews. Sociodemographic details and disposal practices were summarized as frequencies and percentages. The independent t-test and linear regression analysis were used to obtain the determinants. Qualitative data were analyzed thematically. RESULTS: Of the 350 participants (208 males and 142 females), the majority (76%), had good knowledge of e-waste management. Consumers (70%) predominantly had a positive perception. Selling e-wastes to scrap dealers (35%) and disposing of household wastes (21%) were common disposal methods. Male gender, higher education (≥10th grade), and skilled and professional workers were significant determining factors of good knowledge and positive perception toward e-waste management. CONCLUSION: There is a need for those in authority to pay special attention to sensitizing the public to the disposal of e-waste practices, ill effects of e-wastes, segregation at collection sites, legislations and laws on e-waste to consumers, and the establishment of disposal sites.
