Evaluation of CYP1B1, oxidative stress and phase II detoxification enzyme status in oral cancer progression model.

Background: Tobacco is one of the main etiological factors for oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMD). CYP1B1 is an enzyme which plays a major role in the phase I detoxification of tobacco, the byproducts of which are subsequently detoxified by phase II enzymes Glutathione S Transferase (GST). We attempted to evaluate the L432V polymorphism and tissue expression of CYP1B1, along with the oxidant-antioxidant status in OSCC progression model.

Context: Oral squamous cell carcinoma (OSCC) is the sixth most common cancer worldwide. It is mainly known to be caused by tobacco in various forms and also due to viral, fungal infection and poor oral hygiene, etc. Poor oral hygiene leads to colonization of pathogenic bacteria including Helicobacter pylori.

Mortality From Respiratory Syncytial Virus in Children Under 2 Years of Age: A Prospective Community Cohort Study in Rural Maharashtra, India.

Background: Although respiratory syncytial virus (RSV) is the most important viral cause of lower respiratory tract infection deaths in infants, there are few data on infant community deaths caused by RSV.

Methods: This was an active surveillance of children younger than 2 years of age in 93 villages, 5 primary health centers, and 3 hospitals serving these villages. Village health workers and counselors at the health facilities monitored all lower respiratory tract infections (LRTIs) in consented subjects.

The Burden of Respiratory Syncytial Virus in Children Under 2 Years of Age in a Rural Community in Maharashtra, India.

Background: Globally, respiratory syncytial virus (RSV) is a common cause of acute lower tract infection (LRTI) in children younger than 2 years of age, but there are scant population-based studies on the burden of RSV illness in rural communities and no community studies in preterm infants.

Methods: Active surveillance of LRTI was performed in the community and hospital setting for the population of 93 tribal villages in Melghat, Central India, over 4 respiratory seasons. A nasopharyngeal swab was obtained from cases presenting as a severe LRTI for molecular analysis of respiratory pathogens including RSVA and B.

Deciphering the "Collagen code" in tumor progression.

Invasion and metastasis are the fundamental properties of tumor biology and the root causes of cancer death. With the elucidation of genetic and epigenetic mechanisms, it has been postulated that cancer is a disease of imbalance. It is not merely a disease of tumor cells but also the body's mismanagement of those tumor cells.

Assessment of apoptotic index in various grades of oral epithelial dysplasia: A cross-sectional study.

Context: : Oral cancer is a major health problem worldwide. In cancer, the equilibrium between cell proliferation and apoptosis is disturbed. The defect in the apoptotic pathway allows cells to proliferate with genetic abnormalities.

Fibrolipoma on a Child's Lip: A Rare Clinical Finding.

Lipoma is very common benign tumor of adipose tissue, but its presence in the oral cavity is rare. Fibrolipoma is a histological variant of lipoma that affects the buccal mucosa and nasal septum in the orofacial region and causes functional and cosmetic issues. However, this lesion has not been reported on the upper lip and may be confused with other soft tissue lesions of children.

Wheatgrass: Green Blood can Help to Fight Cancer.

Introduction: Oral squamous cell carcinoma is the sixth most common cancer worldwide and is one of the leading causes of death especially in developing countries like India. It is usually managed with the help of chemotherapeutic agents that are toxic not only to the tumor cells but also to normal cells in many ways. Whereas the traditional herbal medicines which are used from ancient days in India are generally known to be free of toxic effects and are effective.

Intraosseous Neurofibroma of the Mandible: A Case Report and Review of Literature.

Neurofibroma (NF) is a benign tumor of the peripheral nervous system. Head and neck NF are generally located in the soft tissue. The tumour is rarely seen intraosseously and most commonly such tumours are seen as solitary lesions, rather than part of neurofibromatosis.

Nerve sheath myxoma of the oral cavity: a distinct entity.

Nerve sheath myxomas (NSM) are uncommon benign tumours of nerve sheath origin. These tumours are most often located in the dermis and subcutaneous tissue of the head and neck region, but less frequently can also involve extracutaneous sites but they are rarely seen in the oral cavity. Many authors consider nerve sheath myxoma and neurothekeoma to be variants of the same tumour, though currently it has been demonstrated that both the lesions are distinct entities with different origins and unique morphological features.

Cd34 and Mast Cell Analysis in Normal Oral Mucosa and Different Grades of Oral Squamous Cell Carcinoma: A Comparative Study.

Background: Oral Squamous Cell Carcinoma (OSCC) remains a serious health problem worldwide. Prognosis of OSCC is poor and long term survival rate still remains below 50%. Angiogenesis or neovascularisation plays an important role in tumour progression and metastasis.

Keratoameloblastoma a rare entity: a case report.

Ameloblastoma is the second most common odontogenic tumour of oral cavity; which has several different histological variants such as follicular, plexiform, acanthomatous, granular cell, desmoplastic, basal cell, clear cell, hemangiomatous, mucous cell differentiation and keratoameloblastoma. It is common in posterior mandible and has high male predilection in the ratio of 3:1. This report presents a case of keratoameloblastoma in 65-year-old female patient in the anterior mandible region with literature review on clinical features, histopathological findings, radiological appearance and treatment options.
