Osteosarcoma of the mandible: A case report with an early radiographic manifestation
Samraj, Lavanya,Kaliamoorthy, Sriram,Venkatapathy, Ramesh,Oza, Nirima Korean Academy of Oral and Maxillofacial Radiology 2014 Imaging Science in Dentistry Vol.44 No.1
Osteosarcoma is a classical malignant bone-forming neoplasm which usually presents with an aggressive clinical course. The current case is presented with the radiographic feature of widening of the periodontal ligament space of the involved teeth, which is considered to be the earliest radiographic manifestation of osteosarcoma involving the jaw bone. The main aim of this case report was to focus on the importance of early diagnosis of this tumor based on clinical and radiographic examinations, and confirmation by histopathology. Considering the rarity of the disease type and particularly taking into account the fast progression and aggressiveness of this neoplasm, it is clear that the presentation of a clinical case represents a major contribution to better understanding of osteosarcomas involving the jaw bone.

COVID-19 (Corona Virus Disease-2019) is an infectious respiratory disease caused by the most recently discovered coronavirus, SARS-CoV-2 (Severe Acute Respiratory Syndrome Corona virus-2). This new viral disease was unknown before the outbreak began in Wuhan, China, in December 2019. As of November 16th 2020, it affects about 54.3 million populations, death troll increased to 1.32 million cases in worldwide. Whereas in India 8.85 cases are infected with COVID-19, of which 1, 30, 112 cases were died. Till now there has been no specific anti-virus drug or vaccines are available for the treatment of this disease, the supportive care and non-specific treatment to the symptoms of the patient are the only options in Biomedicine, the entire world turns its attention towards alternative medicine or Traditional medicine. Siddha medicine is one of the primordial systems of medicine practiced in the southern part of India, it dealt a lot about pandemic, and its management. This review provides an insight into Pandemic in Siddha system and its management in both ancient history and modern history, National and state level Government policies related to current pandemic, World Health Organization (WHO) guidelines on usage of unproven drug during infectious disease outbreak, Preparedness of Siddha system during a pandemic outbreak Challenges and Recommendations.

Ni-W/Al<sub>2</sub>O<sub>3</sub> nano-composites were electrodeposited on mild steel substrate for mechanical and corrosion resistance applications. This study focused on the preparation of Ni-W/Al<sub>2</sub>O<sub>3</sub> nano-composite coating with various quantity of Al<sub>2</sub>O<sub>3</sub> incorporations. The addition of Al<sub>2</sub>O<sub>3</sub> in the electrolytes were varied from 1-10 g/L in electrolytes and the Al<sub>2</sub>O<sub>3</sub> incorporation in Ni-W/Al<sub>2</sub>O<sub>3</sub> nano-composite coatings were obtained from 1.82 to 13.86 wt.%. The incorporation of Al<sub>2</sub>O<sub>3</sub> in Ni-W alloy matrix influenced the grain size, surface morphology and structural properties were observed. The distributions of Al<sub>2</sub>O<sub>3</sub> particle in alloy matrix were confirmed using electron microscopy (FESEM and TEM) and EDAX mapping analysis. The crystal structure informations were studied using X-ray diffraction method and it confirms that the deposits having cubic crystal structure. The better corrosion rate (0.87 mpy) and microhardness (965 HV) properties were obtained for the Ni-W/Al<sub>2</sub>O<sub>3</sub> nano-composite coating with 13.86 wt.% of Al<sub>2</sub>O<sub>3</sub> incorporations.
