Adult CNS Tumors Neurology
This document discusses primary central nervous system (CNS) tumors in adults. It notes that the most common primary CNS tumors are glioblastoma multiforme and meningiomas. Glioblastoma multiforme is the most common malignant primary brain tumor in adults, typically appearing in the brain's white matter. Meningiomas originate from the meninges and present as dura-attached masses that push on the brain. Other primary CNS tumors discussed include hemangioblastoma, schwannoma, oligodendroglioma, and pituitary adenomas. The text provides details on clinical manifestations, diagnostic imaging, histopathological characteristics, and treatments for each of these tumor types.
Symptomatical colloid cyst_Torfs
A 45-year-old male presented with headache after falling and hitting his forehead. Imaging showed a colloid cyst obstructing the third ventricle, causing hydrocephalus. Colloid cysts are benign growths that typically present in adults aged 20-40 with headache and vision changes. They appear as well-defined masses located in the third ventricle on CT and MRI. Surgical removal is the treatment but carries risks of complications like rapid hydrocephalus progression.
Meningioma
Meningiomas are tumors that arise from the meninges, the membranes surrounding the brain and spinal cord. They are usually benign and slow-growing, pressing on brain tissue and causing symptoms like headache. Meningiomas account for about 34% of all primary brain tumors and occur more often in older adults and women. While surgery is often the first treatment, some meningiomas require radiation or other therapies like anti-seizure medications, steroids, or targeted molecular agents depending on their characteristics and response to initial treatment.

- Pathology examines features like cell type, mitoses, and staining for markers like GFAP.
Meningioma
Meningioma is a type of tumor that arises from the meninges, the protective layers surrounding the brain and spinal cord. It is the most common primary brain tumor, accounting for about 20% of all primary central nervous system tumors. Meningiomas most often occur in adults and are more common in women. While the majority of meningiomas are benign, radiation exposure, genetic conditions, and hormone therapy can increase the risk of a malignant type. Imaging plays an important role in the diagnosis and treatment planning of meningiomas.
Medicine 5th year, 1st lecture (Dr. Hassan Al-Jumaily)
This document discusses brain tumors including their types, causes, symptoms, investigations, and management. It describes that brain tumors can be either primary (arising from brain tissue) or secondary (metastatic from other body tissues). The most common types are gliomas like glioblastoma, meningiomas, pituitary adenomas, and metastatic tumors. Symptoms vary depending on tumor size and location but generally include headaches, vomiting, seizures, and focal neurological deficits. Investigations include CT, MRI, and other scans/tests depending on suspected primary tumor location. Management involves symptomatic treatment, surgery, biopsy, radiotherapy, and chemotherapy.
CNS Tumors
Primary CNS tumors can be classified based on their cell of origin and include gliomas, neuronal and glioneuronal tumors, and meningiomas. Gliomas are the most common and include astrocytomas, oligodendrogliomas, and ependymomas. Astrocytomas are graded from I-IV based on malignancy. Childhood CNS tumors often occur in the posterior fossa while adult tumors are more commonly supratentorial. Metastatic tumors account for about a quarter of CNS tumors with the most common primary sites being the lung, breast, skin, and kidney.
Tumors of nervous system
This document discusses tumors of the nervous system. It notes that nervous system tumors are rare but can cause significant morbidity and mortality. The most common primary tumor is glioblastoma, which arises from glial cells. Symptoms vary depending on the location of the tumor but may include headaches, seizures, vomiting, impaired sensorium, focal neurological deficits, and signs of increased intracranial pressure such as papilledema. Diagnosis is made through MRI with contrast and CSF examination. Treatment involves steroids, surgery, radiation, chemotherapy, and ventricular drainage depending on the type and location of the tumor.
Topic of the month: Radiological pathology of meningiomas
This document discusses radiological imaging of meningiomas. It begins by providing background on meningiomas, including that they are the most common primary brain tumor and usually occur in women aged 40-60. On CT scans, meningiomas typically appear dense with calcification and enhance strongly with contrast. On MRI, characteristics vary depending on the histological subtype, with syncytial and angioblastic subtypes more likely to exhibit cysts or increased signal intensity. Location of meningiomas also provides clues to symptoms. The document discusses imaging features of different histological subtypes and common meningioma locations in the brain and spine.
Medulloblastomas
Medulloblastomas are the most common malignant brain tumors in children. They arise in the cerebellum and can spread through the CSF pathways. Complete surgical resection followed by craniospinal irradiation is the main treatment approach. CSI provides improved local and systemic tumor control compared to other radiation techniques based on early studies. Medulloblastomas are highly radiosensitive tumors, making radiation an important part of management, though younger patients and those with residual disease or metastasis have poorer outcomes.
intracranial space occupying lession (pediatrics)
This document discusses intracranial space occupying lesions (ICSOL) in children, including their causes, signs and symptoms, and clinical features. ICSOLs put pressure on the brain and cause damage by disrupting nearby structures, raising intracranial pressure, and causing electrical disturbances. Common causes include tumors, infections like abscesses and cysticercosis, and vascular lesions. Signs and symptoms vary depending on the location of the lesion but can include headaches, vomiting, seizures, cranial nerve palsies, and neurological deficits. Diagnosis is typically made using imaging tests like CT or MRI scans. Treatment involves managing increased intracranial pressure, addressing the underlying cause, and sometimes surgery.

Laws regarding synthetic marijuana in Texas are outlined, classifying it as a Penalty Group 2A controlled substance. Throughout, health risks of each substance are emphasized.
Neurobiology of emotion
This document discusses the neurobiology of emotions. It defines emotions, moods, and affects. The core brain regions involved in emotions are the cerebral cortex, limbic system (particularly the amygdala), and brain stem. The limbic system, including structures like the hippocampus, anterior thalamus, and cingulate gyrus, form circuits important for emotional processing and expression. The amygdala plays a key role in fear and aggression. Other structures like the hypothalamus, prefrontal cortex, and autonomic nervous system are also involved in emotions and physiological arousal. Various neurotransmitters, including monoamines, peptides, GABA, and glutamate mediate emotional processes in the brain.

Adolescent decision making
This document discusses adolescent decision making. It notes that effective decision making is a skill that must be learned and practiced, and ineffective decision making can lead to long-term negative consequences. It outlines cognitive and brain development factors that influence adolescent decision making. Specifically, it discusses how the prefrontal cortex, which controls impulses, is not fully developed in adolescence. This can impair ability to control impulses and increase risk-taking behavior. The document also examines common decision making biases and strategies that can be taught to help adolescents make better decisions, such as considering multiple options and consequences of choices.
Anatomy of emotions
The document discusses the anatomy of emotions and the brain circuits involved. The hypothalamus controls hormones and the pituitary gland, regulates feedback, and responds to stimuli. The limbic system, including the cingulate gyrus, olfactory bulb, thalamus, hypothalamus, fornix, mammilary body, hippocampus, and amygdala, forms a circuit important for emotions. The amygdala receives sensory input and influences emotional responses and behavior by signaling the hypothalamus, while the hippocampus plays roles in spatial awareness, emotion, and memory. The prefrontal cortex communicates bidirectionally with the amygdala and can activate the autonomic nervous system via the hypothalamus

It discusses the history of theories of emotion, key brain structures involved in emotion regulation like the limbic system and its components, and functional circuits in the brain that mediate emotional responses. Specific neurotransmitter systems and how hormones like cortisol are involved in emotions like depression are also summarized. The limbic system, including structures like the amygdala, hippocampus and hypothalamus play important roles in emotional processing and expression. Circuits like the Papez circuit are involved in emotional memory and learning.
The Adolescent Brain
The document discusses changes that occur in the adolescent brain during development. It notes structural, functional, and chemical changes including increased sex hormones and dopamine/serotonin levels. These brain changes impact behavior by making teens more reward-seeking and impulsive with poor decision-making abilities. They may act aggressively one moment and child-like the next. The document provides strategies for teachers, including building relationships, allowing autonomy, and opportunities for safe risk-taking to help guide teens through this period.

BRAIN TUMOR prepared by MS. Neha kewat.pptx
A brain tumor is a mass or growth of abnormal cells in the brain. It can be primary, originating from brain cells, or secondary/metastatic, spreading from other parts of the body. Primary brain tumors are classified based on their origin and include gliomas, meningiomas, and pituitary adenomas. Common symptoms include headache, vomiting, seizures, and visual/sensory changes depending on the location of the tumor in the brain. Diagnosis involves neurological exams, imaging like CT/MRI, and other tests. Treatment options include surgery, radiation, chemotherapy, and medications to relieve symptoms.
Brain Cancer Prognosis
Brain cancers can begin from the primary brain cells, the cells that form other brain elements such as, membrane walls, blood veins, or from the growth of cancer cells that develop in our body organs and that have spread to the brain by the blood vessels.
42925901 brain-tumor
This document discusses brain tumors including their classification, imaging, and characteristics. It notes that cerebral tumors predominantly affect adults aged 55-65 and are relatively uncommon in children. Primary brain tumors can occur at any age but certain tumor types mainly affect specific age groups. Gliomas are the most common primary brain tumor in adults, comprising 45-65% of cases. Low-grade gliomas typically present with seizures and appear hypo-iso intense on CT and homogenously hyperintense on T2 MRI with little enhancement. Anaplastic astrocytomas present similarly but enhance strongly and inhomogenously on imaging.

Benign brain tumors are not
very serious and therefore are
not cause for concern.
Fiction:Benign tumors tend to
grow and crowd out precious
cranial space and, thus, apply
pressure or restrict blood flow to
particular brain regions. If these
benign growths are inoperable
or uncontrolled, they will kill the
victim. Malignant brain tumors
may be lethal, but they may
also be surgically removed or re-
duced with medication or radia-
tion. All brain tumors require at-
tention and may be lethal if left
untreated. Treatment with
surgery, medication, or radiation
is most successful for slowly
growing, encapsulated tumors.

Death to a Killer
N
ot so long ago, your great-grandparent or grandparent may
have suffered from this tragic disease or feared it within his
or her community. Your parents’ generation began to break
free from the grip of this disease, and for today’s generation
this disease has been nearly eradicated. What is this devastating
killer disease? Polio. Polio thrived in the United States and around
the world until the 1950s, especially impacting the postwar “baby
boom” generation. By 1955, Dr. Jonas Salk and Dr. Albert Sabin had
formulated vaccines that put this disease on the shelf. How was that
incredible feat accomplished?
Dr. Jonas Salk’s vaccine consisted of inactivated poliovirus in-
jected intramuscularly, which stimulated production of antibodies
against poliovirus. With the institution of broad-scale immunization
programs ...

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
