random
what is the strongest risk factor of brain tumors?
exposure to ionizing radiation
tumors arising from supporting structures is composed of Meningiomas, pituitary adenomas and acoustic neuroma. Which one is slow growing?
meningiomas. this one is highly vascular and preferred treatment is surgery.
how do we diagnose secondary tumors?
MRI- most helpful diagnostic tool
the effectiveness is limited due to difficulty getting drugs to cross the blood brain barrier
the frontal lobe controls...
movement, decision making, personality, mood, memory
what is the difference between primary brain tumor and secondary/metastatic tumors?
primary brain tumors originates within the CNS. Primary brain tumors rarely metastasize outside the CNS.
Metastatic tumors occur as a result of metastasis from other areas of the body.
tell me about pituitary adenomas?
this cancer is a tumor arising from supporting structures. patients will have a wide variety of symptoms. The most common symptom is a headache.
who is contraindicated for a lumbar puncture?
patients with intracranial pressure
what does chemo need to be mixed in with secondary brain tumors?
a preservative free solution and also a steroid is added to decrease scar tissue
the temporal lobe controls...
speech, hearing, vision, emotions, memory and behavior
what are the two subtypes of primary brain tumors?
Gliomas (arising within the brain tissue/ intracerebral tumors) and tumors arising from supporting structures.
what are secondary brain tumors
tumors arising from another type of body tissue. They spread from the primary site to the brain.
what is the preferred treatment for secondary brain tumors?
growth hormone secreting adenomas produce what in adults?
acromegaly. this appears as deformities. looks at pictures.
the pituitary gland controls...
the occipital lobe controls....
pituitary gland- hormones, growth, and fertility
occipital lobe- vision
the subtype gliomas is made up of Astrocytomas and glioblastomas. Which is most malignant?
glioblastomas are moe malignant.
what do the manifestations of secondary tumors depend on?
they depend on location and size of the tumor.
what should you be careful with when a patient is receiving external beam therapy?
NEVER use alcohol, powder oil or cream without an order. They can cause severe burns during the next treatment.
DO NOT wash the markings off skin that outline area of radiation.
prolactin-secreting pituitary adenomas affect males and females differently. tell me two symptoms for females and two fro males.
females- amenorrhea and galactorrhea
males- impotence and hypogonadism
the parietal lobe controls...
the cerebellum controls...
parietal lobe- reasoning, telling right from left, language, sensation, reading
cerebellum - balance, coordination and fine muscle control
these tumors are commonly divided into 4 grades of increasing pathologic anaplasia and rapidity of progession. describe the grading.
astrocytoma (grade 1 or 2) - well differentiated
anaplastic astrocytoma (grade 3)- intermediate-grade
glioblastoma multiforme (grade 4)- least differential (worst one out there)
glioblastoma multiforme is highly malignant, invasive, grows rapidly and most devastating of primary brain tumors.
what is the common symptom with secondary brain tumors?
headache
what are the types of radiation therapy?
stereotactic radiosurgery- gamma knife
external beam therapy
internal radiation
ACTH Pituitary producing ademonas is associated with what disease
cushing's disease
the brain stem controls...
brain stem- breathing, blood pressure, heartbeat and swallowing
