Link Between Diabetes and TB

There could be link to diet for tuberculosis. It seems people with diabetes are likely to also have tuberculosis in tropical Australia. Little is said about it, but tuberculosis is the leading cause of bacterial death in the world. It has also been known for some time about the predilection to have tuberculosis in people with diabetes.

It could be a "racial" trait. Australian Aboriginals and those of Torres Strait descent are high on the list. having diabetes makes sufferers susceptible to immune dysregulation with opens people to infection generally. It is only rational to screen those with diabetes for tuberculosis. This is not currently done.

It is not known if dysregulation is the cause of problem. Historical data is not much help because diabetes was not an identifiable disease while TB was, in past centuries. Research is being done to find find the reason for it. Reduce the prevalence of diabetes and cases of TB fall. It is as simple as that.

Potentially Lethal Leishmaniasis Affects Many Travelling Abroad

Be careful when you travel abroad - you could bring something unwanted home with you. In 2002 Alfred Heliah and his wife Helene accompanied research scientists on a trip to Peru. They volunteered to assist in the study of red and green macaws. During their visit they were constantly attacked by biting insects. Though they wore protection right down to their wrists they were bitten black and blue.

On their return home the wounds slowly healed. While shaving one morning Alfred noticed what he thought were pimples on the side of his chin. They didn't hurt, but over time they grew larger. They eventually burst, becoming shallow ulcers oozing a yellow discharge. Treating them with antibiotic ointment had no affect.  A new lump appeared and he thought it was time to see a doctor.

After being told by Alfred that he had recently returned from the tropics in Peru, doctors at the local hospital believed that he had leishmanisis that could devour the flesh on his face. It causes major damage to the spleen leading to death. The disease is transmitted by the humble sandfly. Leishmania parasites live in the sandfly's gut and it is vomited into open wounds.

Though the general public has hardly heard of the disease it is endemic to eighty-eight countries. During Desert Storm in Iraq twenty US soldiers came down with the parasitic infection. After returning home, eight more came down with the disease.

Getting back to Alfred. A tropical disease specialist Dr Angami examined him and asked how many were on the team in Peru, Alfred told him about thirty. The Doctor frighteningly replied that some more in the group would have the disease by now.

Biopsies showed that Alfred did indeed have Leishmaniasis. He was given Pentostam, a nitrogenic metal and a medication never approved by the FDA - the only treatment available. Patients must sign away any damages entitlement from the medication's side effects. After only three days with Pentostam being infused into his blood Alfred began to improve. Though he felt worse, doctors could see he was recovering. Alfred did recover. However, there was always the possibility of infectious bumps reappearing at any time in the future. A side effect of Pentostam is tremor in the hands. Alfred had to live with this for the rest of his life. When Alfred was offered a research trip to Africa, he turned it down. He had suffered enough.

Dangerous Chemicals in Household Products

Be careful what you put on your skin - the skin absorbs chemicals on its surface. In other words your body consumes and ingests things like soap and toxins in engine oil, etc. Little research is done on this serious issue. In New Zealand a dangerous chemical which lowers IQ in children has been found in sunscreens. It is as damaging as lead paint.

Even spraying the chemical into the air where is can be breathed in and ingested can lower IQ. Piperonyl butoxide is also present in insect spray. Cancer Society products even contain the substance.

Low vitamin D has been blamed for many diseases when in fact it could be trace chemical in commonly used household goods. If vitamin D deficiency is causal then people in temperate countries would have higher cancer, Alzheimer's, heart disease, autism, depression and ADHD than those in tropical regions. This is only true for some of these illnesses. Too say 31 per cent of Australians in this hot country are deficient is ridiculous.

Rain Forest in Northern Australia Doing Well

The northern part of Australia is getting hotter, but it is no drier. A comparison of data from the 1950s and the present shows the borders between rain forest and eucalyptus forest remained the same. However, the density of rain forest increased by 732 ha. Neither drainage, geology, topography, aspect or elevation are responsible. The climate has definitely changed. Despite a series of El Nino dry spells since the 1950s, the country is becoming wetter.

This rain forest expansion has slowed over the last 2000 years, with 25 per cent being tall open forest. Eucalyptus forests are spread out in irregular shaped pockets which are very stable. Higher CO2 is responsible for the increasing density of rain forest. The humidity keeps damage from fires low.

Overall, this is good news for the world generally. Brazilian rain forest stores 250-300 C ha–1 (carbon per hectare). Though Australian rain forest stores less, it is still significant. There is a possibility that local factors in Australia are having this effect. Yet indicators do point to global warming.
