BACKGROUND Oral squamous cell carcinoma (OSCC) is the sixth most common cancer globally. Tobacco consumption and HPV infection, both are the major risk factor for the development of oral cancer and causes mitochondrial dysfunction. Genetic polymorphisms in xenobiotic-metabolizing enzymes modify the effect of environmental exposures, thereby playing a(More)
The results of reconstruction of the anterior floor of the mouth, using 105 nasolabial flaps in 79 patients were reviewed in a retrospective study. Of those flaps, 82% healed uneventfully; flap survival was 95%. Considerable flap loss occurred in 5%. Primary dehiscence was observed in 5% of all flaps. This healed spontaneously with conservative therapy. In(More)
BACKGROUND The taxonomic validity of Northeast Indian endemic Mahseer species, Tor progeneius and Neolissochilus hexastichus, has been argued repeatedly. This is mainly due to disagreements in recognizing the species based on morphological characters. Consequently, both the species have been concealed for many decades. DNA barcoding has become a promising(More)
A 10-year retrospective study was undertaken to investigate perioperative complications in pharyngeal flap surgery in one institution using inferiorly and superiorly based flaps. In this fashion the current practice of surgical technique based on local findings and perioperative care, through regular monitoring by experienced nurses on the ward, was(More)
Cleft lip with or without cleft palate [CL(P)] has a high prevalence [corrected] in the northern Netherlands. Several epidemiological parameters for oral clefts, including both CL(P) and cleft palate (CP), were analysed and compared with the literature. Except for the high prevalence at birth of isolated CL(P) no major differences in the pattern of(More)
Genetic polymorphisms in tobacco-metabolizing genes may modulate the risk of head and neck cancer (HNC). In Northeast India, head and neck cancers and tobacco consumption remains most prevalent. The aim of the study was to investigate the combined effect of cytochrome P450 1A1 (CYP1A1) T3801C, glutathione S-transferases (GSTs) genes polymorphisms and(More)
Three patients with an isolated arthritis in the hand are described. All three had long-term complaints and had undergone surgery before presenting in our clinic. The cause of arthritis, in all three patients, was a juxta-articular osteoid osteoma. In one patient the diagnosis was established by a plain X-ray. Additional radiological studies were necessary(More)
BACKGROUND Catfishes are globally demanded as human food, angling sport and aquariums keeping thus are highly exploited all over the world. North-East India possess high abundance of catfishes and are equally exploited through decades. The strategies for conservation necessitate understanding the actual species composition, which is hampered due to sporadic(More)
Several studies from developing countries have shown human papillomavirus to be associated with colorectal cancers, but the molecular characteristics of such cancers are poorly known. We studied the various genetic variations like microsatellite instability (MSI), oncogenic mutations and epigenetic deregulations like CpG island methylation in HPV associated(More)
We describe a patient whose both hands were amputated at the level of the wrist in an accident with a farm machine. Both hand were replanted. In spite of an extremely severe injury and consequently a bad prognostic situation an acceptable functional result was obtained. This patient is capable of performing his daily activities reasonably well. He can also(More)
