In children, this approach is not supported by evidence, except in high prevalence areas. Urea breath testing and stool antigen testing perform better than serology-based tests; moreover, serology may be false-positive after treatment with IVIG. Other agents
Dapsone (also called diphenylsulfone, DDS, or avlosulfon) is an anti-infective sulfone medication. Dapsone may also be helpful in treating lupus, rheumatoid arthritis, and as a second-line treatment for ITP. The mechanism by which dapsone assists in ITP is unclear but an increased platelet count is seen in 40–60 percent of recipients. The off-label use of rituximab, a chimeric monoclonal antibody against the B cell surface antigen CD20, may sometimes be an effective alternative to splenectomy. However, significant side-effects can occur, and randomized controlled trials are inconclusive. Prognosis
In general patients with acute ITP will only rarely have life-threatening bleeding. most of the patients ultimately have stable but lower platelet counts which is hemostatic for a person. Unlike in pediatric patients who can be cured; most of the adults will run a chronic course even after splenectomy

Epidemiology
A normal platelet count is considered to be in the range of 150,000–450,000 per microlitre (μl) of blood for most healthy individuals. Hence one may be considered thrombocytopenic below that range, although the threshold for a diagnosis of ITP is not tied to any specific number.The incidence of ITP is estimated at 50–100 new cases per million per year, with children accounting for half of that number. At least 70 percent of childhood cases will end up in remission within six months, even without treatment.
Sesamoiditis is inflammation of the sesamoid bones. Humans
Sesamoiditis occurs on the bottom of the foot, just behind the big toe. There are normally two sesamoid bones on each foot; sometimes sesamoids can be bipartite, which means they each comprise two separate pieces. The sesamoids are roughly the size of jelly beans. The sesamoid bones act as a fulcrum for the flexor tendons, the tendons which bend the big toe downward. Symptoms include inflammation and pain. Sometimes a sesamoid bone is fractured. This can be difficult to pick up on X-ray, so a bone scan or MRI is a better alternative.Among those who are susceptible to the malady are dancers, catchers and pitchers in baseball, soccer players, and football players. Horses
In the horse it occurs at the horses fetlock. The sesamoid bones lie behind the bones of the fetlock, at the back of the joint, and help to keep the tendons and ligaments that run between them correctly functioning. Usually periostitis (new bone growth) occurs along with sesamoiditis, and the suspensory ligament may also be affected. Sesamoiditis results in inflammation, pain, and eventually bone growth. Causes
In humans, excessive forces caused by sudden bending upwards of the big toe, high heels, or a stumble can contribute to sesamoiditis. Once the sesamoid bone is injured it can be very difficult to cure, because additional pressure is put on the sesamoid bone during walking.
