BACKGROUND Tumor necrosis factor-alpha (TNF alpha), which we and others have shown to be elevated in patients with severe congestive heart failure (CHF), is involved in the regulation of nitric oxide metabolism. Whether increased concentrations of TNF alpha affect nitric oxide-mediated vasodilation in patients with CHF has not been studied previously. (More)
Candida species present both as commensals and opportunistic pathogens of the oral cavity. For decades, it has enthralled the clinicians to investigate its pathogenicity and to improvise newer therapeutic regimens based on the updated molecular research. Candida is readily isolated from the oral cavity, but simple carriage does not predictably result in(More)
Salivary gland neoplasms present with a diverse histological pattern which is mainly because of the presence of specialized myoepithelial cells (MECs). These are contractile epithelial cells with smooth muscle like properties. They have been also noticed in mammary glands, lacrimal glands, prostate gland, and the sweat glands and have varied functions. MECs(More)
The presence of teeth at birth or within a month post-delivery is a rare condition. A newborn, a 2 days old female, with two mandibular incisor natal teeth was examined. The teeth were mobile and were extracted because of the fear of aspiration and refusal to feed. The purpose of this report is to review the literature related to natal teeth epidemiology(More)
Primary intraosseous mucoepidermoid carcinoma of the jawbones is an extremely rare malignant salivary gland tumour constituting 2-4.3% of all the reported mucoepidermoid carcinomas. We report a case of intraosseous mucoepidermoid carcinoma of the mandible in an 80-year old female patient developing from a previously diagnosed dentigerous cyst. An excisional(More)
Odontomas are considered to be hamartomas rather than a true neoplasm. They consist chiefly of enamel and dentin, with variable amount of pulp and cementum when fully developed. They are generally asymptomatic and are included under the benign calcified odontogenic tumors. They are usually discovered on routine radiographic examination. Eruption of an(More)
UNLABELLED To study the influence of left bundle branch block (LBBB) on the signal-averaged electrocardiogram (SAECG), quantitative and qualitative analyses of SAECG parameters were undertaken in 48 patients with electrocardiographic evidence of intrinsic LBBB and in 39 patients with a "normal" surface QRS duration (less than 120 msec) who underwent right(More)
BACKGROUND The mortality and morbidity associated with oral squamous cell carcinoma (OSCC) can be greatly reduced if tumor markers which can detect OSCC at an early stage are available. The use of saliva as an alternative to blood could provide a substantial advantage in sampling convenience. Cancer antigen 125 (CA 125) is a tumor-associated antigen found(More)
CONTEXT Inducible nitric oxide synthase (iNOS) is a cytoplasmic enzyme which plays a crucial role in the pathogenesis of oral carcinomas and sarcomas. AIMS The objective of this study was to analyze the immunohistochemical expression of iNOS in carcinomas and sarcomas affecting the oral cavity in order to understand the possible role of iNOS in their(More)
BACKGROUND In routine histopathology, xylene has been used in tissue processing and staining. Presently health hazards of xylene are well documented and a safer substitute is an absolute necessity. AIM The present study was conducted to evaluate the efficacy of mineral oil as a deparaffinizing agent when compared to that of xylene by using hematoxylin and(More)
