Investigation of energy recovery from poultry litter and municipal solid waste by thermochemical conversion method in India.

The waste disposal is becoming a major threat to environmental issues and to sustainable development of mankind. The rapid growth in population and enormous developmental activities are the main causes for the generation of waste in many forms. Hence there is need to redress the concern on environment and efforts to be made for effective collection and disposal of wastes. Most of the solid waste is a mix of household wastes, street wastes, commercial and institutional wastes containing organic as well as inorganic matter. This offers better opportunity to recover energy from organic fraction of wastes by adapting suitable processing and treatment technologies. This paper describes the various technologies need to be adopted for the disposal of poultry waste and municipal solid waste. More emphasis has been given on waste disposal technologies for better environment and economics. The advantages and disadvantages of each disposal technology have been briefed.

Scurvy--a forgotten disease.

A four-year-old male child was reported with sudden inability to stand walk of 10 days duration. Acute paralytic poliomyelitis was diagnosed in the presence of fever, respiratory infection, muscle tenderness, and weakness in lower extremity in an unimmunized child. Reevaluation after a week showed swelling, thickening, and tenderness of left femur. Plain x-ray of the left thigh was advised to exclude underlying osteomyelitis of the femur. X-ray showed features of scurvy. The child responded well to parenteral vitamin C therapy and resumed normal walking with in two weeks. Scurvy can present as pseudoparalysis of acute onset without any other signs even in older children. It emphasized the need for an index of suspicion of scurvy in a case of suspected paralysis. Dramatic response to vitamin C therapy can be used to confirm the diagnosis in the absence of laboratory support. Health education can be accelerated to prevent a disease like scurvy.
