INTRODUCTION An odontogenic myxoma (OM) is a rare ,benign and locally aggressive odontogenic tumor characterised by gross replacement of cancellous bone by gelatinous or mucoid tissue ,thus leading to cortical bone expansion. It originates from the embryonic mesenchymal elements of the developing tooth. World Health Organisation has categorized OM as a benign tumor of ectomesenchymal origin with or without presence of odontogenic epithelium.1 They are slowly progressing ,asymptomatic, and site-aggressive
Molecular techniques such as polymerase chain reaction and DNA sequencing have improved the understanding of relationships between different groups of animals, and mechanisms underlying evolutionary change. The advancement in technology has gradually changed the scientific concepts generated about evolutionary relationships. Techniques such as DNA hybridisation (as shown in the picture below), amino acid sequencing and the analysis of the antibody-antigen reaction between species have shown the similarities
Abstract Fibrous Dysplasia is an uncommon bone disease due to an underlying gene mutation causing replacement of normal bone by fibro osseous connective tissue. It exists in mono and polyostotic forms.FD presents mostly between 3 and 15 years of age and without any gender variation. Bone pains and fractures are the most common presenting features. Radiological studies are done to support the diagnosis of FD. Recent evidences shows the efficacy of intravenous pamidronate in the treatment of FD along
should be performed according to the case c. Resorption usually stops after treatment, internal bleaching may be performed for esthetic reasons. VIII. DISEASES OF PERIRADICULAR TISSUE OF NON-EDONTOGENIC ORIGIN Benign Lesions: a. Ossifying fibroma b. Myxoma c. Ameloblastoma d. Solitary bone cyst e. Lateral periodontal cyst f. Central hemangioma g. Central giant cell granuloma Diagnosis: a. Teeth are vital b. Surgical biopsy is necessary for final diagnosis Malignant Lesions: a. Squamous cell carcinoma
A virus can host shift from animals to humans by evolving and adapting to their new host. The virus has to be able to adapt to their new host by adjusting the enzymes to a new temperature and invading different kinds of cells from their previous host. Viruses spread amongst their hosts species accordingly to each kind. For instance, birds spread the influenza viruses by contaminating water with their droppings. However, the virus adapted to humans by spreading through the airway therefore allowing
ORTNER'S SYNDROME - A RARE CAUSE OF UNILATERAL VOCAL CORD PARALYSIS Abstract Patient presented with hoarseness due to vocal cord paralysis secondary to cardiovascular pathology is an extremely rare entity, better known as cardiovocal syndrome or Ortner's syndrome. The common underlying pathology was described as an enlargement of the left atrium or recurrent laryngeal nerve compression by the pulmonary artery. We report a case of undiagnosed congenital heart disease in a young lady presented to
