READING 11: COMPLEMENTARY & ALTERNATIVE MEDICINES
A.
DEFINITION:
Every available
approach to healing that does not fall within the realm of conventional
medicine. The boundaries of alternative medicine are constantly changing as
different types of care are becoming more accepted by doctors & more
requested by patients.
Some alternative
medicine practices are homeopathy, naturopathy, chiropractic, acupuncture &
herbal medicine. Alternative medicine is often associated with complementary
medicine using the term CAM (Complementary
& Alternative Medicine). Therefore,
both herbal remedies & meditation, as well as other treatments, fall under
the heading of CAM.
B.
HOW CAM
DIFFERS FROM TRADITIONAL MEDICINE?
Alternative therapy is
frequently described with holistic methods, which means that the doctor or
practitioner treats the “whole” person & not just the disease or condition.
In alternative medicine, many practitioners address patients’ emotional &
spiritual needs as well. This “high touch” approach differs from the “high
tech” practice of traditional medicine, which tends to concentrate on the
physical side of illness.
C.
TYPES OF ALTERNATIVE
CARE:
1.
MIND-BODY MEDICINE: This includes practices such as meditation,
prayer, Tai Chi & music therapy, which are intended to develop the mind’s
ability to affect physical symptoms.
2.
BIOLOGICALLY BASED PRACTICES: These include
substances such as herbs, foods, vitamin dietary supplements. Herbal remedies
include a variety of plants used for medicine or nutrition. They are available
in grocery stores, over the Internet, in health food store or through
herbalists.
3.
MANIPULATIVE & BODY-BASED PRACTICES: These practices are
based on the manipulation or movement of body parts. It includes methods like
massage therapy & therapeutic touch, which manipulate & realign body
parts, to help alleviate symptoms.
4.
ENERGY MEDICINE: This area of medicine is based on the theory
(which has not been proved scientifically) that certain energy fields surround
and penetrate the body. It also includes therapies based on bioelectromagnetics
– the theory that electrical currents in all living organisms produce magnetic
fields that extend beyond the body.
1ST
HOMEOPATHY:
Every person has an
energy called a vital force or self-healing response. When this energy is
disrupted or imbalanced, health problems develop. Homeopathy seeks to stimulate
the body’s defense mechanism & processes so as to prevent or treat
illness.
Homeopathic treatment
involves giving extremely small doses of substances, called remedies, that
produce the same or similar symptoms of illness in healthy people when given in
large doses. Most homeopathic remedies are derived from natural substances that
come from plants, minerals or animals. Remedies are sold in liquid, pellet &
tablet forms. Treatment in homeopathy is individualized (tailored to each
patient). Homeopathic practitioners select remedies according to a total picture of the patient, including
not only symptoms but also lifestyle, emotional, mental states & other factors.
2ND
CHIROPRACTIC:
“Chiropractic is a
heal care discipline which emphasizes the power of the body to heal itself
without the use of drugs & surgery” (Chiropractic College).
The chiropractic
perspective on health & disease emphasizes 2 fundamental concepts:
1.
The
structure & condition of the body influences how the body functions &
its ability to heal itself.
2.
The
mind-body relationship is instrumental in maintaining health & in the
healing process.
A healthy,
well-aligned spinal column moving with full range of motion allows the nervous
system to perform properly, which is vital because it controls every function
of your body. The brain & the nerve systems assemble & transmit
information necessary to ensure the proper coordination of the body. The spinal
system, consisting of the vertebras, the spinal cord & the spinal nerves,
carries this information from the brain to all parts of the body.
Chiropractic
philosophy emphasizes a holistic approach (total person) to healing which
combines elements of the mind, body & spirit. It maintains that health
depends on obedience to natural laws & deviation from such laws can result
in illness.
Despite debate about
the effectiveness of chiropractic, it seems to be most effective for acute low
back pain & tension headaches. Upper cervical spinal manipulation may be
beneficial for certain types of hypertension.
3RD
HERBALISM:
1.
DEFINITON:
Herbalism is a
traditional medicinal or folk medicine practice based on the use of plants
& plants extracts. Many plants synthesize substances that are used for
preserving health in human & animals. Human also use many herbs &
spices as season food. The scope of herbal medicine is also extended to include
fungi & bee products, as well as minerals, shells & certain animal
parts.
2.
ROLE OF HERBAL
MEDICINE IN MODERN HUMAN SOCIETY:
The use of herbs to
treat diseases is almost universal among non-industrialized societies. Herbal
medicines are a major component in all traditional medicine systems & a
common element in homeopathic, naturopathic, traditional Chinese medicine &
native American medicine. Herbal medicines, such as opium, aspirin digitalis
& quinine have been used since ancient times. The use of, & search for, drugs &
dietary supplements derived from plants have increased in recent years.
3.
SOME PLANTS WITH
THERAPEUTIC EFFECTS:
Here are some
well-known plants whose therapeutic effects are usually recognized.
a.
Artichoke: Traditional use as
well as recent clinical studies continue to verify the multi-beneficial effects
of the artichoke leaf extract including lipid-lowering, anti-oxidative,
hepato-protective; as well as aiding dyspepsia & abdominal pain where the
stomach, gallbladder, liver & pancreas are primarily affected.
b.
Soy: Rich in vitamins
& minerals. Soy may lower risk of prostate, colon & breast cancers as
well as osteoporosis & other bone health & menopause problems.
c.
Feverfew: Sometimes used to
treat migraine. It should be avoided for
pregnant women or patients taking blood-clotting medications.
d.
Garlic: Lowers cholesterol,
improves blood flow, fights bacteria & viruses.
e.
Green tea: Lower chances of
heart diseases & certain types of cancer.
f.
Lemon grass: Lower cholesterol
levels.
g.
Valerian root: Used against sleeping
disorders, restlessness & anxiety. Also used as a muscle relaxant.
h.
Papaya: Used for insecticidal
purposes (killing ice, worms).
4.
RISKS CONNECTED TO THE
USE OF HERBAL MEDICINES:
Many consumers believe
that herbal medicines are safe while many interact with synthetic drugs causing
toxicity to patients. Some herbal remedies may have the potential to cause
adverse drug interaction when used in combination with various prescription
& OTC pharmaceuticals.
Therefore,
proper double-blind clinical trials are needed to determine the safety &
efficacy of each plant before they can be recommended for medical use.
READING 12: DEPRESSION – COMMON DISTURBANCE IN THE MODERN WORLD
A.
DEFINITION:
Depression may be
described as feeling sad, blue, unhappy, or miserable. Most of us feel this way
at one time or another for short periods. True clinical depression is a mood
disorder in which feelings of sadness, loss, anger, or frustration interfere
with everyday life for weeks or longer.
B.
POSSIBLE CAUSES & RISK FACTORS:
The exact
cause of depression is not known. Many researchers believe that it is caused by
chemical changes in the brain. This may be due to a problem with your genes or
triggered by certain stressful events. Some types of depression run in families
but depression can also occur if you have no family history of the illness.
Anyone can develop depression, even kids.
The
following may play a role in depression: Alcohol or drug abuse - Certain
medical conditions, including underactive thyroid, cancer or
long-term pain - Certain medications such as steroids - Sleeping problems -
Stressful life events (Breaking up with a boyfriend or girlfriend; Failing a
class; Death or illness of someone close to you; Divorce; Childhood abuse or
neglect; Job loss; Social isolation, especially common in the elderly).
C.
SYMPTOMS:
Depression
can change or distort the way you see yourself, your life and those around you. People who have depression usually see
everything with a more negative attitude, unable to imagine that any problem or
situation can be solved in a positive way. This feeling is totally dangerous if
not treated immediately with the right method or medication because the
patients may develop more terrible reactions: self-torture or even, commit
suicide.
Symptoms of
depression can include: Agitation, restlessness, and irritability - Dramatic
change in appetite, often with weight gain or loss - Very difficult to
concentrate - Fatigue and lack of energy - Feelings of hopelessness and
helplessness - Feelings of worthlessness, self-hate, and guilt - Becoming
withdrawn or isolated - Loss of interest or pleasure in activities that were
once enjoyed - Thoughts of death or suicide - Trouble sleeping or excessive
sleeping - Depression can appear as anger and discouragement, rather than
feelings of sadness.
D.
MEDICATIONS FOR DEPRESSION:
In general,
treatments for depression include: Medications called antidepressants - Talk
therapy, called psychotherapy.
Drugs used to treat depression are called
antidepressants. Common types of antidepressants include: Selective serotonin
re-uptake inhibitors (SSRIs) - Serotonin norepinephrine reuptake inhibitors
(SNRIs). Other medicines used to treat depression include: Tricyclic
antidepressants - Bupropion - Monoamine
oxidase inhibitors.
WARNING: Children, adolescents, and young adults should be
watched more closely for suicidal behavior, especially during the first few
months after starting medications.
If you do not feel better with antidepressants and
talk therapy, you may have treatment-resistant depression. Lithium and thyroid hormone
supplements also may be added to help the antidepressants work better.
CHANGES IN MEDICATIONS: Sometimes,
medications that you take for another health problem can cause or worsen depression.
Talk to your doctor about all the medicines you take. Your doctor may recommend
changing your dose or switching to an alternative drug. Never stop taking your
medications without first talking to your doctor. Women being treated for
depression who are pregnant or thinking about becoming pregnant should not stop
taking antidepressants without first talking to doctors.
TALK THERAPY: Talk therapy is counseling to
talk about your feelings and thoughts, and help you learn how to deal with
them.
Types of
talk therapy include:
• Cognitive behavioral therapy: Teaches you how to
fight off negative thoughts. You will learn how to become more aware of your
symptoms and how to spot things that make your depression worse. You'll also be
taught problem-solving skills.
• Psychotherapy: Can help you understand the issues that may be
behind your thoughts and feelings.
• Joining a support group of people who are sharing problems like yours
can also help. Ask your therapist or doctor for a recommendation.
E.
PREVENTIONS:
Do not drink
alcohol oruse illegal drugs. These substances can make depression worse and
might lead to thoughts of suicide. Take your medication exactly as your doctor
instructed. Ask your doctor about the possible side effects and what you should
do if you have any. Learn to recognize the early signs that your depression is
getting worse.
The
following tips might help you feel better: Get more exercise - Maintain good
sleep habits - Seek out activities that bring you pleasure - Volunteer or get
involved in group activities - Talk to someone you trust about how you are
feeling - Try to be around people who are caring and position.
READING 13: BIOTECHNOLOGY & BIOPHARMACEUTICALS
A.
DEFINITION:
Biotechnology is a
technology based on biology, especially when used in agriculture, food science
& medicine. Or: “Any technological application that uses biological
systems, living organisms, or its derivatives, to make or modify products or
processes for specific use” (UN Conventions on Biological Diversity). The term
BIOTECHNOLOGY is used to manipulate & modify organisms & in applying
biological research techniques to the development of products that improve
human health, animal health & agriculture.
B.
BIOPHARMACEUTICALS:
Biopharmaceutical
refers to complex biological medical products manufactured by biotechnology
methods/ processes. Biopharmaceuticals can treat human diseases that may not be
accessible to traditional medicines. A patient is typically dosed with a small
molecule via a tablet while a large molecule is typically injected. Small
molecules are manufactured by chemistry but living cells, such as those found
in the human body (bacteria cells, yeast cells, animal or plants cells) create
large molecules.
Biotechnology is also
commonly associated with landmark breakthroughs in new medical therapies to
treat hepatitis B, hepatitis C, cancers, arthritis, hemophilia, bone fractures,
multiple sclerosis & cardiovascular disorders.
C.
TRANSGENICS:
Nowadays,
biotechnology refers more & more to the production of Genetically Modified
Organisms (GMO). This potentially controversial method means producing
biopharmaceuticals involving transgenic organisms, particularly plants &
animals that have been genetically modified to produce drugs. This also has
some risks: the failure to produce the required organism or the disapproval by
the government due to the perceived risks & ethical issues.
READING 14: DIETARY SUPPLEMENTS
A dietary supplement
(or food supplement) is a preparation intended to supply nutrients (vitamins,
minerals, fatty acids or amino acids) that are missing or not consumed in
sufficient quantity in a person’s diet. Some countries define dietary
supplements as foods while others view as drugs.
Dietary
supplement pyramid:
1.
Special needs: vision, healthy heart, joint flexibility,
menopause, sports nutrition.
2.
Antioxidants (such as vitamins E & C): Cell protection
& repair.
3.
Calcium supplements: Building & keeping strong,
healthy bones.
Multivitamin with minerals
with 400mcg folic acid: Foundation of a supplement plan for everyone.
