- ItemSmartphone-based fluorescence spectroscopy device aiding in preliminary skin screening(2018-02-13) Sahoo, Aparajita; Wahi, Akshat; Das, AnshumanPreliminary diagnosis of closely resembling skin conditions can be highly subjective for dermatologists. In ambiguous cases, it often leads to performing invasive procedures like biopsies. Different skin conditions, however, have varying concentrations of fluorophores (like collagen, NADH) and chromophores (like melanin, hemoglobin) which can alter their fluorescence spectra. We demonstrate a handheld, portable, smartphone-based spectrometer that leverages these alterations in skin autofluorescence spectra for rapid screening of skin conditions. This methodology involves excitation of affected skin areas with ultraviolet (UV-A) 385 nm light, capturing the generated fluorescence spectra and sending the data wirelessly to a companion mobile application for data storage, analysis and visualization. By collecting the fluorescence spectral signals from healthy and unhealthy skin conditions, we establish that the signals collected using this portable device can be used to develop a classification method to help in differentially diagnosing these conditions. It shows promise as a useful skin screening tool for both dermatologists and primary health care workers. This device can enable quick, non-invasive and a more objective preliminary examination. We envision the device to be especially useful in primary healthcare centers of developing countries where availability of dermatologists is limited.
- ItemA novel clip-on for smartphone dermoscopy in India(Healthcare Innovations and Point of Care Technologies (HI-POCT), 2017 IEEE, 2017-11-08) Sahoo, Aparajita; Wahi, Akshat; Patel, Sonali; Poojary, Shital; Jaiswal, Saurabh; Das, AnshumanDermoscopy is the in vivo technique of skin surface microscopy which is frequently used in visual examination of the skin. With the rise in the usage of smartphones, many smartphone attachments have been developed that enable dermoscopy on a phone but these attachments are very expensive and are available only for high-end phones. We have developed a novel 3D printed clip-on that can convert any smartphone into a polarizing dermoscope at a price which is highly affordable than the existing devices and is universal in its design. After visual examination and comparing images taken by both the devices using Structural Similarity Index (SSIM), we found the images to be highly similar. This clip-on for smartphones is one of the first prototypes using techniques of 3D printing which can make dermoscopy affordable, especially in developing countries like India. There is an acute need for such devices by clinicians practicing in remote areas, where such clip-ons can help in improving the preliminary visual examination of a large number of patients.
- ItemWorking Women to Working Mother: A Transition in the Indian Society(Indian Institute of Management, Banglore, 2012-08) Kumar, ChitralekhaOne of the significant changes witnessed by the Indian societies is the status of working women and their excellent management skills. Gone are the days when the women were only a homemaker at the end of the day. The transition of women to successful working women took ages but finally, they have come out with flying colors. With the advances in the norms of society, adaptability of the male members of the family, better education system, flexible work environment and the willingness of women to succeed has finally paved way for a better and secure career for the women of today's era. A woman has to play multiple roles. The present paper attempts to understand the management of roles between an expecting mother and an employee going on a maternity leave. The present paper is based on an exploratory qualitative study of 12 women from academic institutions in Mumbai, India. The outcome of the research reveals four themes: Clear communications; support from the family and coworkers; organizational policies and practices; balancing the role conflict.
- ItemTraining the Hospital Staff: A Path Towards Better Management of Biomedical Waste(International Conference on Biomedical Waste Management, 2012-07) Kumar, Chitralekha; Agarwal, Sudhir
- ItemStrategies and Policies for Collection and Transportation of Biomedical Waste(Tenth AIMS International Conference on Management, 2013-01) Kumar, Chitralekha; Laveti, Pallavi; Haldankar, SiddeshThe paper in detail will look at the protocols followed by the different medical facilities across various hospitals in Maharashtra during segregation and disposal of the waste.The paper will also help in understanding the awareness levels of the medical staff with respect to different methods and training involved in disposing off this waste.
