Idiopathic thrombocytopenic purpura (ITP) is a disorder that can lead to easy or excessive bruising and bleeding. The bleeding results from unusually low levels of platelets — the cells that help blood clot. Idiopathic thrombocytopenic purpura, which is also called immune thrombocytopenia, affects children and adults. Children often develop ITP after a viral infection and usually recover fully without treatment. In adults, the disorder is often long term. If you don't have signs of bleeding and your platelet count isn't too low, you may not need any treatment. In rare cases, the number of platelets may be so low that dangerous internal bleeding occurs. Treatment options are available.
As long as the ureter is large enough to allow the ureteroscope to pass, there is a good chance that the stone can be broken and removed with one surgery. Compared to SWL, a kidney or ureteral stone can be seen under direct vision by the ureteroscope, allowing lithotripsy with lasers followed by basketting and removal.

Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.
Non-Hodgkin's lymphoma, also called non-Hodgkin lymphoma, is cancer that originates in your lymphatic system, the disease-fighting network spread throughout your body. In non-Hodgkin's lymphoma, tumors develop from lymphocytes — a type of white blood cell. Non-Hodgkin's lymphoma is more common than the other general type of lymphoma — Hodgkin lymphoma. Many different subtypes of non-Hodgkin's lymphoma exist. The most common non-Hodgkin's lymphoma subtypes include diffuse large B-cell lymphoma and follicular lymphoma.
