This presentation provides an overview of multiple sclerosis (MS). It defines MS as an immune-mediated demyelinating disease of the central nervous system where myelin is destroyed. Symptoms can include sensory and mobility issues as well as cognitive and psychological problems. Diagnosis involves MRI, lumbar puncture, and evoked potential studies. Management focuses on symptomatic treatment and disease-modifying drugs. Nursing care aims to improve mobility and elimination while preventing injury through safety measures and assistive devices. Recent studies examine cognitive dysfunction in MS and its effects on daily living.

Myasthenia gravis (MG) is a long-term neuromuscular disease that leads to varying degrees of skeletal muscle weakness. The most commonly affected muscles are those of the eyes, face, and swallowing. It can result in double vision, drooping eyelids, trouble talking, and trouble walking.
Craniotomy
A craniotomy involves making an incision in the scalp and creating a hole known as a bone flap in the skull. The hole and incision are made near the area of the brain being treated.
During open brain surgery, it is done to remove tumors, clip off an aneurysm, drain blood or fluid from an infection & remove abnormal brain tissue
Decompressive craniectomy
It is a neurosurgical procedure in which part of the skull is removed to allow a swelling brain room to expand without being squeezed. It is performed on victims of traumatic brain injury, stroke and other conditions associated with raised intracranial pressure.
Increased intracranial pressure is defined as cerebrospinal fluid pressure greater than 15 mm Hg.
Infections
Tumors
Stroke
Aneurysm
Epilepsy
Seizures
Hydrocephalus
Hypertensive brain injury
Hypoxemia
Meningitis
Due to etiological factors
Components of ICP is disturbed- brain tissue, CSF, blood volume
An increase in the volume of ANY ONE component must be accompanied by a reciprocal decrease in one of the other components.
When this volume-pressure relationship becomes unbalanced, ICP increases.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

2. Multiple sclerosis
Introduction – it is an immune mediated
demyelinating disease of the CNS.
Demyelination refers to destruction of myelin,
the fatty and protein material that surround
the nerve fibres in the brain and spinal cord,
it result in impaired transmission of nerve
impulse.
3. Neurons
Cell bodies
Form the grey matter ( grey
matter found in periphery of
brain, centre of spinal cord )
Group of cell bodies called
Nuclei ( CNS )
Ganglia ( PNS )
Axon & dendrites
Form the white matter (
white matter found in
centre of brain, periphery
of spinal cord )
Group of axon called
Tract ( CNS )
Nerves ( PNS )

6. Incidence
It occurs between the age of 20-50 years.
It mostly affect to the female than male.
Definition
It is a chronic, progressive, non contagious,
degenerating disease of the CNS
characterized by the demyelination of the
neurons.
7. Etiology
• Unknown
• Immune system attack it own tissue so it is
considered an autoimmune disease.
• Factor
Age – 20-50 years of age
Gender – female
Certain infection – Epstein barr virus
Temperature climate
Smoking
Autoimmune disease - DM

9. Clinical manifestation
• Disruption of sensory axon may produce sensory
dysfunction such as pain, paresthesia (pricking
sensation).
• Spasticity (unusual "tightness", stiffness, or
"pull" of muscles) of the extremities results
from involvement of the main motor pathway of
the spinal cord.
• Cognitive and psychological problems involve
frontal lobe and parietal lobe.
• Euphoria – due to loss of connection between
cortex and basal ganglia.
10. • Bowel, bladder and sexual dysfunction.
• Advanced symptoms –
Pronounced difficulty in moving
Severe visual impairment

14. Diagnostic evaluation
• History and Physical examination
• MRI – reveal plaque or lesion around demyelinated
neuron.
• EEG
• CSF Electrophoresis– presence of immunoglobulin G
(normal protein is 15-45mg/dl) elevated 10 mg/dl then
normal
• Evoked potential studies – it measure electrical activity
in the brain in response to stimulation of sight, sound, or
touch. When the brain is stimulated by sight, sound, or
touch, signals travel along the nerves to the brain.
There, electrodes detect the signals and display them
for your doctor to interpret.
17. 2. Disease modifying drugs
A. Interferon beta 1a – it suppress immune
system and helps to maintain blood brain
barriers.
E.g. - Avonex – I/M, once a week
Rebif – S/C three times a week
B. Interferon beta 1b – used to treat the
relapsing-remitting and secondary-progressive
forms of multiple sclerosis. It is given.
E.g. – Betaseron, S/C in every 2 days
18. C. Glatiramer Acetate – it decrease the
reoccurrence of relapse. S/C, daily.
D. Methylprednisolone – treat acute relapse. It
relieve inflammation act on T-Cells & cytokines.
1 gm IV daily for 3 days
3. Alternative complementary therapies
It include Acupuncture, Aromatherapy (oil), Cold
immersion, Dietary supplements, Herbal
medication, Massage, Meditation, Yoga and
19. Venom such as snake and bee-Bee venom
is a mixture of many substances. The pain and
swelling of the sting are caused by histamine,
dopamine, serotonin, and norephinephrine. Several
toxins are also present, including apamin, melittin,
monoamine, and mast-cell degranulating peptide.
Lastly, the substances responsible for the allergic
response include hyaluronidase and phospholipase-
A2, enzymes that work to activate immune cells and
produce immunoglobulin E (IgE). Bee venom is a
complex mixture, and it is not known how its
components affect the human body or interact with
autoimmune conditions such as MS.
20. Complication
• Paralysis

27. Recent studies regarding the MS
Cognitive dysfunction in multiple sclerosis: a
review of recent developments
Purpose of review: Nearly half of all patients
diagnosed with multiple sclerosis will develop
cognitive dysfunction, a symptom associated
with significant decline in activities of daily
living. The purpose of this review is to discuss
recent literature investigating issues related to
cognitive dysfunction in multiple sclerosis.
28. Cont....
Recent studies, examined in this review, have
provided increased understanding regarding
specific cognitive processes affected in multiple
sclerosis, as well as a characterization of its
natural history. Studies have also continued to
emphasize the extent to which cognitive deficits
in the condition are associated with decline in
daily living skills. Recent concerns regarding
driving performance have been documented
among cognitively impaired individuals.
29. Cont.....
Studies have also examined correlates of
cognitive dysfunction, with particular emphasis
on neuro-imaging techniques reflecting disease
activity or lesion burden. With increased
understanding of neurobiological correlates of
cognitive deficits, investigators have begun to
examine potential treatments for managing
cognitive dysfunction.
