    Sentinel Lymph Node Biopsy : A new approach in the management of head and neck cancers

    Cervical lymph node metastasis affects the prognosis and overall survival rate of and therapeutic planning for patients with head and neck squamous cell carcinomas (HNSCCs). However, advanced diagnostic modalities still lack accuracy in detecting occult neck metastasis. A sentinel lymph node biopsy is a minimally invasive auxiliary method for assessing the presence of occult metastatic disease in a patient with a clinically negative neck. This technique increases the specificity of neck dissection and thus reduces morbidity among oral cancer patients. The removal of sentinel nodes and dissection of the levels between the primary tumour and the sentinel node or the irradiation of target nodal basins is favoured as a selective treatment approach; this technique has the potential to become the new standard of care for patients with HNSCCs. This article presents an update on clinical applications and novel developments in this field.

    Deciphering the Role of the Barr Body in Malignancy: An insight into head and neck cancer

    Get PDF
    X chromosome inactivation is the epitome of epigenetic regulation and long non-coding ribonucleic acid function. The differentiation status of cells has been ascribed to X chromosome activity, with two active X chromosomes generally only observed in undifferentiated or poorly differentiated cells. Recently, several studies have indicated that the reactivation of an inactive X chromosome or X chromosome multiplication correlates with the development of malignancy; however, this concept is still controversial. This review sought to shed light on the role of the X chromosome in cancer development. In particular, there is a need for further exploration of the expression patterns of X-linked genes in cancer cells, especially those in head and neck squamous cell carcinoma (HNSCC), in order to identify different prognostic subpopulations with distinct clinical implications. This article proposes a functional relationship between the loss of the Barr body and the disproportional expression of X-linked genes in HNSCC development

    Verrucous Hyperplasia : Case report and differential diagnosis

    Verrucous hyperplasia (VH) is a rare exophytic oral mucosal lesion which can transform into verrucous carcinoma (VC), its malignant but clinically similar counterpart. These entities can be distinguished by the lack of invasive growth in VH cases; as such, it is essential to include a margin with adequate depth whenperforming a biopsy of the epithelium of the lesion. We report an 80-year-old male patient who presented to the Bapuji Dental College & Hospital, Davangere, Karanataka, India, in 2011 with a warty whitish-pink growth on the inside of his cheek. The patient was treated with wide surgical excision of the lesion and a diagnosis of VH was made based on histopathological features. There was no evidence of recurrence at a five-year follow-up. This report highlights the histological variations, pathogenesis and differential diagnosis of VH

    A Study on Penchant for E-Learning

    Abstract — E-Learning, in the most basic terms, is utilization of technology to support delivery of education without any restriction on time and place. It can be said that it’s a nonlinear and flexible approach, when viewed with reference to the traditional approach. Traditional way of learning or the classroom learning largely bounds the learner in terms of content and time besides putting restriction on user’s pace of learning. By making excellent use of information and communication technologies, E-Learning offers competent solution to learner, keeping in view one’s environment variables and reader’s own pace and learning power. The learner controls his interactions with the content modules. Of course the efficiency of any E-learning module depends on learner’s attitude towards learning and technology, availability and access to technology and his own technical background. This paper broadly analyzes the desire and openness, of students, to accept E-Learning as platform of providing education in addition to the traditional systems of learning. A combination of such system is called Blended Learning. This research paper has fivefold objective. The paper begins with analysis of students ’ perception of e-learning in higher education. The focus then shifts to students ’ basic internet usage and ease of performing basic computer operations. The next part of study focuses students ’ use of application software. Lastly the paper analyses students’ openness to electronic mode of learning. The study has been conducted through surveys on student enrolled in various graduate and post graduate courses in Chandigarh

    Post-traumatic extensive scalp ulceration: A diagnostic and management challenge!

    Dissecting cellulitis of scalp (DCS) is an uncommon inflammatory dermatosis, which can be difficult to diagnose in the absence of concomitant cutaneous markers. We present an interesting case of DCS in a 60-year-old male, with an onset after blunt trauma to head. The progression was fast and diagnosis could be achieved on multiple biopsies only. The response to therapy with a combination of oral isotretinoin and intralesional triamcinolone acetonide injections is highlighted in this difficult to treat dermatoses
