Based on recent studies, the growth hormone deficiency is the most common hormone deficiency that occurs in patients with brain cancer that undergoes intracranial radiation therapy. Most often, this hormone deficiency is diagnosed in cancer patients that experienced long exposures to high-dose radiation therapy on the hypothalamus. Radiation-induced growth hormone deficiency can develop in various settings. However, is it mostly seen in patients with CNS tumors after undergoing localized radiation therapy for face, carcinomas of the orbit, sarcomas and nasopharynx. Other side effects of radiation therapy include skin problems, fatigue, hair loss, nausea and vomiting, loss of appetite, and low blood cell counts.

The best way to prepare skin for electrode application that I could find was to shave the hair the day before if necessary, and wash the skin with a damp towel or alcohol swab before drying the area off thoroughly. This will ensure that the electrodes don’t stick uncomfortably or pull at the hairs on the area the electrodes will be placed. One other thing you want to do before placing electrodes on someone’s skin is to make sure there are no abrasions or cuts. Electricity takes the fastest way to the ground. If there’s an open sore or abrasion, it’s fewer layers of skin to go through. The electricity will prefer that and the patient may become uncomfortable before the data is taken.

1. severe lower back pain, decreased blood pressure, decreased rbc count, increased wbc count.-severe lower back pain indicates an aneurysm rupture, secondary to pressure being applied within the abdominal cavity. when ruptured occurs, the pain is constant because it cant be alleviated until the aneurysm is repaired. blood pressure decreases due to the loss of blood. after the aneurysm ruptures, the vasculature is interrupted and blood volume is lost, so blood pressure wouldnt increase. for the same reason, the rbc count is decreased not increased. the wbc count increases as cell migrate to the site of injury.

1. severe lower back pain, decreased bp, decreased rbc, increased wbc -severe lower back pain indicates an aneurysm rupture, secondary to pressure being applied within the abdominal cavity. when rupture occurs, the pain is constant because it cant be alleviated until the aneurysm is repaired. blood pressure decreases due to the loss of blood. after the aneurysm ruptures, the vasculature is interrupted and blood volume is lost, so blood pressure wouldnt increase. for the same reason, the rbc count is decreased not increase. the wbc count increases as cells migrate to the site of injury.

All of the above conditions can cause temporary reversible ECI. These include the presence of CNS depressants. There are a wide range of CNS depressant that include diazepam, meprobamate, mecloqualone, methaqualone, and barbiturates. Apart from that, Hypothermia can also be a leading cause where the temperature is less than approximately 32 degrees Celsius. Furthermore, cardiovascular shock is another condition that can cause temporary reversible ECI. Other causes include severe metabolic disorder and endocrine disorder. This condition is also common among newborn babies that have neurologic birth defects/injuries. There are many other causes that are still being discovered by medical researchers.

A technologist would be knowledgeable in the technology industry. They would be able to differentiate between different technological features and items that they see. One may be a photoelectric artifact. A photoelectric artifact is an artifact that induces light. An ERG stands for electroetinography which has to do with the eye. The difference between these two is that covering the electrode should eliminate the photocell or photoelectric artifact and covering the eye should eliminate the ERG response. Photoelectric refers to the association of electrical results caused by radiation when the radiation interacts with forms of matter. An ERG response may be needed if someone was having an eye disease and needed a doctor to do something about it soon before it progressed into something worse.

HPN Continuous pressure on the vessel walls from hypertension causes the walls to weaken and an aneurysm to occur. Atherosclerotic changes can occur with peripheral vascular diseases and are linked to aneurysms, but the link isnt as strong as it is with hypertension. Only 1% of clients with syphilis experience an aneurysm. Diabetes mellitus doesnt have direct link to aneurysm.
