Types of Brain and Spinal Cord Tumors in Adults
Tumors that start in the brain (primary brain tumors) are not the same as tumors that start in other organs, such as the lung or breast, and then spread to the brain (metastatic or secondary brain tumors). In adults, metastatic tumors to the brain are actually more common than primary brain tumors. These tumors are not treated the same way. For example, breast or lung cancers that spread to the brain are treated differently from tumors that start in the brain.
Unlike cancers that start in other parts of the body, tumors that start in the brain or spinal cord rarely spread to distant organs. Even so, brain or spinal cord tumors are rarely considered benign (non-cancerous). They can still cause damage by growing and spreading into nearby areas, where they can destroy normal brain tissue. And unless they are completely removed or destroyed, most brain or spinal cord tumors will continue to grow and eventually be life-threatening.
Brain and spinal cord tumor grades
Some brain and spinal cord tumors are more likely to grow into nearby tissues (and to grow quickly) than are other tumors. The World Health Organization (WHO) divides brain and spinal cord tumors into 4 grades (using Roman numerals I to IV), based largely on how the cells look under the microscope:
- Grade I: These tumors typically grow slowly and do not grow into (invade or infiltrate) nearby tissues. They can often be cured with surgery.
- Grade II: These tumors also tend to grow slowly but they can grow into nearby brain tissue. They are more likely to come back after surgery than grade I tumors. They are also more likely to become faster-growing tumors over time.
- Grade III: These tumors look more abnormal under the microscope. They can grow into nearby brain tissue and are more likely to need other treatments in addition to surgery.
- Grade IV: These are the fastest growing tumors. They generally require the most aggressive treatment.
Gliomas
Gliomas are not a specific type of brain tumor. Glioma is a general term for tumors that start in glial cells. A number of tumors can be considered gliomas, including:- Astrocytomas (which include glioblastomas)
- Oligodendrogliomas
- Ependymomas
About 3 out of 10 of all brain tumors are gliomas. Most fast-growing brain tumors are gliomas.Astrocytomas
Astrocytomas are tumors that start in glial cells called astrocytes. About 2 out of 10 brain tumors are astrocytomas.Most astrocytomas can spread widely throughout the brain and blend with the normal brain tissue, which can make them very hard to remove with surgery. Sometimes they spread along the cerebrospinal fluid (CSF) pathways. It is very rare for them to spread outside of the brain or spinal cord

A police force paid almost £10,000 to a convicted child rapist to act as an undercover informant during a major sex abuse investigation, it can be revealed.
Northumbria Police paid the man to infiltrate parties where young girls were being drugged and abused by an Asian grooming gang. The man - known only as Mr XY - was recruited by the force even though he was convicted in 2002 of drugging and raping a teenage schoolgirl and inviting another man to rape her.
In 2014 detectives signed him up as a Covert Human Intelligence Source (CHIS) as they tried to smash a child sex ring operating in the west end of Newcastle upon Tyne.
Details of the case can only now be reported following the conviction of the final members of the 18 strong gang.
The group, which included one white woman, were convicted of carrying out harrowing abuse against at least 22 vulnerable girls.
Last night child protection campaigners expressed deep unease about putting a convicted paedophile on the police payroll. But Northumbria Police's Chief Constable, Steve Ashman, defended the decision, insisting as unpalatable as it was, it had led to vulnerable people being protected from harm.
The force paid XY regular instalments over 21 months amounting to £9,680 in order to pass information to officers about the time and locations of parties where young girls were being abused.
But it can now also be revealed that in 2015, while still on the police's payroll, he was arrested on suspicion of another child sex offence.
He was arrested after an underage girl told police a man had approached her and had made an indecent proposition.
The case was subsequently dropped although the circumstances why remain unclear. XY's role with the police only came to light during a court hearing last year when lawyers acting for some of the abusers argued that his involvement in the investigation undermined the entire case.
During the hearing, defence lawyer, Robin Patton, described him as: "A convicted child rapist who drugged a child and invited someone else to rape her after he had."
It also emerged he had numerous convictions for dishonesty, was on the Sex Offenders Register and was actually serving a suspended sentence when he was initially deployed by police in 2014.
Giving evidence from behind a screen and with the public gallery cleared, XY told the hearing that he had been a paid informant for six or seven years and had enjoyed working for the police.
He claimed he had been recruited because he acted as an informal taxi driver for some of the defendants.
"I would get to know where they pick up their drugs, where the parties were," he said.
At another point, he claimed: "I was chilling with the boys. I had to make it look like I was their friend.

Introduction to magnesium
Magnesium, an abundant mineral in the body, is naturally present in many foods, added to other food products, available as a dietary supplement, and present in some medicines (such as antacids and laxatives). Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation Magnesium is required for energy production, oxidative phosphorylation, and glycolysis. It contributes to the structural development of bone and is required for the synthesis of DNA, RNA, and the antioxidant glutathione. Magnesium also plays a role in the active transport of calcium and potassium ions across cell membranes, a process that is important to nerve impulse conduction, muscle contraction, and normal heart rhythm
An adult body contains approximately 25 g magnesium, with 50% to 60% present in the bones and most of the rest in soft tissues, Less than 1% of total magnesium is in blood serum, and these levels are kept under tight control. Normal serum magnesium concentrations range between 0.75 and 0.95 millimoles (mmol)/L, Hypomagnesemia is defined as a serum magnesium level less than 0.75 mmol/L [ Magnesium homeostasis is largely controlled by the kidney, which typically excretes about 120 mg magnesium into the urine each day, Urinary excretion is reduced when magnesium status is low .
Assessing magnesium status is difficult because most magnesium is inside cells or in bone, The most commonly used and readily available method for assessing magnesium status is measurement of serum magnesium concentration, even though serum levels have little correlation with total body magnesium levels or concentrations in specific tissues, Other methods for assessing magnesium status include measuring magnesium concentrations in erythrocytes, saliva, and urine; measuring ionized magnesium concentrations in blood, plasma, or serum; and conducting a magnesium-loading (or “tolerance”) test. No single method is considered satisfactory, Some experts, but not others consider the tolerance test (in which urinary magnesium is measured after parenteral infusion of a dose of magnesium) to be the best method to assess magnesium status in adults. To comprehensively evaluate magnesium status, both laboratory tests and a clinical assessment might be required.

Plague is caused by the bacteria Yersinia pestis, and circulates among rabbits and rodent populations. Symptoms can include:
- fever
- headache
- weakness
- pain or swelling of the groin, armpit or neck.
Plague infections in people can occur in three forms: bubonic, septicemic, or pneumonic, depending on route of exposure. Bubonic plague or septicemic plague often results from flea bites or contact with infected animal fluids or tissues. People with bubonic plague can develop swollen, tender lymph nodes called “buboes”. Septicemic plague is more severe, and causes bleeding into the skin and other tissues. Skin and tissue necrosis can also occur, especially on the fingers, toes, and nose. Pneumonic plague often results when a person breathes in infectious droplets. People can experience shortness of breath, chest pain, cough, pneumonia, and respiratory failure.
In Arizona, plague is found in most areas of Arizona above 4,500 feet elevation and activity occurs in prairie dog, ground squirrel, and rat populations.
Arizona 5 year median: 0 cases
Transmission
Plague is spread by the bite of infected fleas. Plague can also be spread through direct contact with blood or tissues of infected rodents, rabbits, or other animals. It is possible for pneumonic plague to be spread from person to person (e.g. coughing). Isolation Precautions
Standard and droplet precautions are recommended in healthcare settings.
Prevention for Patients
Prevention methods include:
Prevention methods include:
- Avoid contact with sick or dead animals, especially rodents and rabbits.
- Stay away from rodent burrows.
- Reduce rodent habitats around home and work environments.
- Remove brush, rock piles, firewood, and possible food sources.
- Do not feed wildlife, including rodents.
- Wear insect repellant to keep fleas away when hiking or working in areas where plague might be active.
- Always wear protective equipment, including gloves and mask, when handling wildlife in the field (e.g. skinning and cleaning game).
- Keep fleas off pets by using flea prevention for cats and dogs.
Public Health Actions
Environmental partners should be notified to determine source of exposure and potential animal die-off.
Environmental partners should be notified to determine source of exposure and potential animal die-off.
Public health will conduct an epidemiological investigation on a case or suspect case.
Public health will follow-up with pneumonic plague contacts for seven days after last exposure to the case.

Lyme disease is a tick-borne disease caused by the spirochete bacterium Borrelia burgdorferi. The majority of cases in the United States come from endemic states in the Midwest and East coast areas. Lyme disease is not endemic to Arizona due to the absence of the species of tick that spreads the bacteria. Asking travel history is very important to assessing risk for Lyme disease.
Symptoms tend to be nonspecific and may include: fever, fatigue, chills, headache, muscle and joint aches, and swollen lymph nodes. A red, expanding rash called erythema migrans occurs at the site of the tick bite in approximately 70-80% of cases. Typically, rashes present as the hallmark “bull’s-eye” pattern.
Arizona 5 year median: 13 cases
Transmission
Lyme disease is spread through the bite of an infected Ixodes tick.
Lyme disease is spread through the bite of an infected Ixodes tick.
Incubation period from the initial bite to the appearance of erythema migrans lesions ranges from 1 to 32 days.
