The fuel pumps on the Porsche Cayenne are one of those items that are in the not if, but when it fails items. As a general rule, I recommend changing both fuel pumps at the same time. I've seen plenty of cases where someone replaced one side, only to have the remaining pump fail in a few days.
Prophylactic cranial irradiation (PCI) or prophylactic cranial radiotherapy (PCRT) is a technique used to combat the occurrence of metastasis to the brain in highly aggressive cancers that commonly metastasize to brain, most notably small-cell lung cancer.[1] Radiation therapy is commonly used to treat known tumor occurrence in the brain, either ...
Unfortunately, there are rare patients who simply donât tolerate brain radiation very well. For some of these patients, we need to simply quit the radiation altogether. There are also rare patients who simply donât recover very well after treatment, and the effects of fatigue can be long lasting in this group. Another way of assessing tolerability has been from reviewing work on prophylactic cranial irradiation (PCI). This work has generally shown it to be quite well tolerated, with the main side effects being headache in just over 40% of patients, nausea and/or vomiting in about 1/3, and a smaller proportion of around 10% or less with fatigue.
