United Nations’ Sustainable Development Goal targets to make cities and human settlements inclusive, safe, resilient, and sustainable; as it is predicting 95% urban expansion in the next decades. Consequently, urban livability can serve as a useful conceptual and analytical framework to improve the quality of urban life by facilitating the evaluation of the person–environment relationship and leading the improvement without deteriorating the environmental conditions. This present paper aims to identify the dimensions and indicators of subjective and objective livability for Siliguri Municipal Corporation (SMC). The residents’ perception has been carried out using stratified random sampling technique. Samples have been collected from the residents from each core, semi-periphery and peripheral areas of SMC. Mainly, adaptation of Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) model involves four livability dimensions; under which the overall model explains 65% of the total variance indicating with the high reliability (α > 0.7) and the Goodness-of-fit index (GFI) about 0.90. The result indicates that, ‘Accessibility Factor’ bears the highest impact (24.91%) among the four latent variables and ‘Socio-Economic’ factor has the lower impact (8.39%) upon the urban livability.

BACKGROUND Erythroderma or exfoliative dermatitis is an inflammatory disorder, it covers > 90% of the body surface. Hebra proposed it first in 1868. Pre-existing dermatoses comprised majority of cases and these include psoriasis, spongiotic dermatoses, pityriasis rubra pilaris, lichen planus, pemphigus foliaceus etc. Erythroderma is a common clinical presentation of different diseases in this region. Aim-Erythroderma is a serious disease. Histopathological confirmation of causes is urgently required to optimise the therapy. MATERIALS AND METHODSClinically diagnosed 22 cases of erythroderma who presented to NBMC and H between December 2016 and July 2017 were evaluated and correlation of clinical diagnosis with histopathological features was studied. Results were then analysed. RESULTSMales were affected more than females and chronic spongiotic dermatitis was the most common cause. Erythroderma secondary to malignancy was not observed in this study. Majority (91%) of erythroderma cases clinically present as a chronic disease and t he most common presenting feature was itching (77.27%). Overall prognosis was good in our study with drug-induced cases. CONCLUSIONErythroderma secondary to pre-existing dermatoses is the major cause with insidious onset and geographic variation.
