Smallpox was a serious problem in the 20th century. The World Health Organization declared in 1979 that smallpox was no longer a danger to the world's population. The aim has been to "silence" other diseases. It was hoped that polio could also be eradicated, but a stubborn region for this has remained in Pakistan. More cases were identified in Pakistan than in any other country in 2011. The Edhi Foundation, a major charity, and the Pakistan government are working with the Global Polio Eradication Initiative to target the disease. Cases have fallen so that now Nigeria is the main trouble spot. There are fears that the progress could be short lived and figures could rise again. Polio spreads far more easily than smallpox. The smallpox vaccine lasts for five years and is very effective. For the war on polio to be won, just about every person must be vaccinated. As the disease can only spread from person to person this goal must be achieved. http://www.adventure--aus...

Only Western people get depressed due to their fast way of living - right? Unfortunately, this is not the case. Those in developing countries are also stressed as they struggle to survive. While Westerners do not have to worry too much about securing food, getting adequate sustenance for themselves and families is in many cases the main priority for the Third World population. An examination of depression in developing countries by the University of Queensland on 480,000 subjects highlights this disturbing finding. People in Third World nations just do not go to doctors for treatment. The survey in 91 countries shows that stress is common across the board. There is a fine line between depression and stress. Many would say they are the same thing. Anxiety was found to be higher in the USA with depression there being the lowest. Examining depression specifically, developing countries had more than twice the rate of the US - 9 per cent. Political and military conflict was the main...

It seems we can study what animals looked like even though they are extinct. Australian and New Zealand scientists are studying prehistoric feathers to find out what birds were like. DNA has been obtained from the extinct Moa bird of New Zealand from feathers 2,500 years old. Moa are thought to have been still alive 1200 years ago It was 8 feet tall and could not fly. Material has been gleaned from three types of Moa: the stout legged; the heavy footed; and the upland Moa. Somehow they have worked out that wing feathers had speckled white tips. This was to camouflage the bird from predators. The very large Haast eagle once existed that preyed on them. It is claimed that because the plumage of other flightless NZ birds is dull with speckled tips this idea is valid. The scientists plan to get feathers from the end of the quill and further down the quill to compare coloration. It is hoped the findings will enable researchers to correctly reconstruct life-like models of extinct birds. h...

The medical community has just noticed a fact that many have known for years - Waiting a long time for an operation can lead to opioid addiction. It is easy to get opiates from GPs just by telling them that you are in excruciating pain and an operation is a long way off. Shane Jackson president of the Tasmanian Pharmaceutical Society says money should be spent on more pain management specialist. This is a waste considering they only tell patients to take paracetamol that does not stop strong pain. Setting up a data base will only lead to patients being denied opiates so they experience more pain and suffering. Blame the patients has always been easy to do. A data base will stop people getting morphine derivatives from all GPs. This creates an added problem. The solution is more medical staff and facilities to do more operations. Reducing the risk of opiate addiction can be solved by denying patients access to such drugs, Though they may turn up in the hospital emergency departme...

Treatment for heart disease is advancing at a rapid pace. Soon, a tiny piece of artery will be removed from a patient and a new heart conduit will be formed. This is for minor problems in the heart, less that 5mm wide. Conduits are also being made from synthetic materials. Toleration of foreign substances is not a problems because it degrades quickly. They are used to go over the outside of a graft to stop bleeding. The synthetic conduits are made of a fine poly-(glycerol sebacate) net coated with polycaprolactone and the anticoagulant heparin. Mesh holes are too small for blood to pass through. Nothing of the implant remains after three months. A new structure of endogenous cells with M2 macrophages (which reduces inflammation) remains. Though tests have only been done on rats, use in humans will probably be just as successful. Large grafts using the material will be done to see if this is feasible. This will be a welcome advance in medicine. A graft made of the body's ...
