* ODR (pmp) – Organ Donation Rate (per million population)
In the year 2000 through the efforts of an NGO called MOHAN Foundation state of Tamil Nadu started an organ sharing network between a few hospitals. This NGO also set up similar sharing network in the state of Andhra Pradesh and these two states were at the forefront of deceased donation and transplantation programme for many years. As a result, retrieval of 1,033 organs and tissues were facilitated in these two states by the NGO.Similar sharing networks came up in the states of Maharashtra and Karnataka; however, the numbers of deceased donation happening in these states were not sufficient to make much impact. In 2008, the Government of Tamil Nadu put together government orders laying down procedures and guidelines for deceased organ donation and transplantation in the state. These brought in almost thirty hospitals in the programme and has resulted in significant increase in the donation rate in the state. With an organ donation rate of 1.15 per million population, Tamil Nadu is the leader in deceased organ donation in the country. The small success of Tamil Nadu model has been possible due to the coming together of both government and private hospitals, NGOs and the State Health department. Most of the deceased donation programmes have been developed in southern states of India. The various such programmes are as follows:

In the year 2012 besides Tamil Nadu other southern states too did deceased donation transplants more frequently.
Osteoporotic bone marrow defect is a condition which may be found in the body of the mandible. It is usually painless and found during routine radiographs. It appears as a poorly defined radiolucency (dark area) where there was a previous history of an extraction of a tooth. It may resemble a metastatic disease. It is a localized increase of hematopoietic bone marrow that creates a radiolucent radiographic defect. They occur more commonly in women in the midyears and show a predilection for the molar region of the mandible. They are especially common in extraction sites. Scattered trabeculae may extend short distances into the defect or, in some instances, through it, giving the defect a fairly characteristic appearance. Naturally there are no clinical symptoms. Cause
The cause remains unknown. Diagnosis
Differential diagnosis
This defect may easily be mistaken for a cyst or tumor. Biopsy is required to rule these out. Treatment
No treatment is required. References
