Commercial HIV-1 genotypic resistance assays are very expensive, particularly for use in resource-constrained settings like India. Hence a cost effective in-house assay for drug resistance was validated against the standard ViroSeq HIV-1 Genotyping System 2.0 (Celera Diagnostics, CA, USA). A total of 50 samples were used for this evaluation (21 proficiency(More)
BACKGROUND HIV type-1 (HIV-1) monitoring in resource-limited settings relies on clinical and immunological assessment. The objective of this study was to study the frequency and pattern of reverse transcriptase (RT) drug resistance among patients with immunological failure (IF) to first-line therapy. METHODS A cross-sectional study of 228 patients with IF(More)
High costs and stringent requirements for storage and transport of plasma, often prohibit the availability of HIV viral load quantification in resource-limited settings. Dried blood spots (DBS) represent a better method of specimen collection that removes many of these logistical and technical limitations. The present study aimed to assess the performance(More)
Ameloblastic carcinoma is a rare lesion of odontogenic origin. It is defined as a malignant epithelial odontogenic tumor that histologically has retained the features of ameloblastic differentiation and also exhibits cytologic features of malignancy, like atypia and mitotic activity. Although this lesion represents a separate entity, differentiating it from(More)
BACKGROUND A cross-sectional study among individuals receiving second-line antiretroviral treatment was conducted to report on the level of detectable viremia and the types of drug resistance mutations among those with detectable human immunodeficiency virus (HIV) type 1 plasma viral loads (PVLs). METHODS PVLs were measured using Abbott m2000rt real-time(More)
UNLABELLED Identification of individuals is a challenging task in forensic odontology. In circumstances where identification of an individual by fingerprint or dental record comparison is difficult, the palatal rugae may be considered as an alternative source. Palatal rugae have been shown to be highly individualistic and it maintains consistency in shape(More)
Oral cancers constitute a significant proportion of hospital admissions among cancer patients in India. The aim of this study was to elucidate the role of tumour suppressor gene p53 in the pathogenesis of oral squamous cell carcinoma by immunohistochemistry. Though extensive studies on p53 alterations in oral cancers have been done in Western countries and(More)
PURPOSE To retrospectively analyse the frequency and distribution of various biopsied lesions of the gingiva among patients attending a dental teaching institution in Karnataka state in India. MATERIALS AND METHODS Data collected from 153 gingival biopsies referred to the Department of Oral Pathology, Yenepoya Dental College in Mangalore, Karnataka state,(More)
