After examining the same tissue using electron microscopy, he was able to identify the presence of silicon, aluminum, and other soil metals both in the phagosomes of macrophages and adhered to the surface of lymphocytes. Price demonstrated that the lymphatic vessels of these patients experienced subendothelial edema and eventual collagenization of the lumen leading to complete blockage. He wrote a monograph on podoconiosis which was published after his death in 1990. Current situation
Podoconiosis is now recognised as one of the WHO Neglected Tropical Diseases, its importance as a public health problem is well recognised in Ethiopia. Footwork is a charity which bring together public and private partners to support prevention and treatment of podoconiosis. There is an active research group led by Gail Davey at the Wellcome Trust Brighton and Sussex Centre for Global Health Research which co-ordinates research worldwide. A recent article in The Lancet includes some excellent illustrations. References

When a person receives one changed form of the gene AGU from one of the parents, the individual is then classified as a carrier. Diagnosis
In order to be diagnosed with AGU an individual takes a urine test, which will show indication of an increased amount of aspartylglucosamin being secreted. The confirmation of the diagnosis of aspartylglucosaminuria requires a blood test. This helps show if the enzyme aspartylglucosaminidase is present or partially absent. A skin simple will also show the amount of aspartylglucosaminidase present. Pre-natal diagnosis
When families have a child who has already been diagnosed with AGU, they have the option to observe the enzymes activity that codes for AGU in future pregnancy, to help determine if the next child will also have a positive diagnosis for aspartylglucosaminuria. Treatment
No treatment is available to cure or slow down the progression of aspartylglucosaminuria. Bone marrow transplants have been conducted in hope that the bone marrow will produce the missing enzyme. The results of the tests thus far have shown to be inconclusive.
