Temporal Lobe Seizure
Other names: Psychomotor seizure, TLE
Temporal lobe seizures are
periods of unconsciousness and involuntary movement that result
from abnormal electrical activity in the temporal
lobe portion of the brain. They may occur only once in a person’s
life or may be recurring.
Temporal lobe seizures can occur
at any age and may be caused by a number of factors, including
injury, brain tumors or even a high
fever. Symptoms may include:
- Funny feelings in the abdomen
- Hallucinations
- Déjà vu or the sensation of a recalled
memory
- Uncontrolled muscle movement
- Abnormal head or mouth movements
- Numbness
Diagnosis is based on symptoms and the results of diagnostic
tests, such as an EEG, CT scan and spinal tap. Treatment varies based
on the severity of the condition. First-aid may be administered to prevent
the person from injuring herself or others and to prevent an
airway obstruction. Prescription medications also may be ordered
to prevent
future seizures.

Temporomandibular
Disorders (TMD)
Temporomandibular disorders are
conditions that involve the temporomandibular joint, which
includes the muscles
used in chewing. According to the National Institutes of Health,
more
than 10 million Americans have symptoms of TMD.
Normally, the temporomandibular
joint is used during chewing, swallowing and speech. Some believe
that strenuous exercise and
stressful
situations may cause TMD. Most discomfort is caused
by bruxism,
which is clenching or grinding teeth. Symptoms, which may affect
one or both sides of the jaw, include:
- Pain
in the cheek
- Difficulty opening or closing the jaw
- A clicking sound coming
from the jaw
- Headaches
- Earache without infection
TMD is diagnosed based on symptoms, patient
history and X-rays. As many as 50 treatments are available
to treat TMD, and
the
treatment recommended may vary. In many cases, the condition can be improved by resting the joint,
taking a non-aspirin pain reliever and practicing stress management
techniques.

Tendinitis
A tendon attaches your muscles to your bones. When a tendon
becomes inflamed or irritated, it causes tendinitis. Tendinitis
is characterized by pain, tenderness, stiffness, swelling and/or
discomfort
in a joint. Tendinitis is most often caused by a sports-related
injury or physical labor. Tendinitis occurs mainly
in the
elbow,
knees and shoulder – but can affect any joint. Tendinitis
is also caused by the aging process, which causes joints to weaken
due to
wear and tear over a lifetime of activity. When tendonitis affects
specific areas, it is often called something else. For example,
tendonitis of the elbow and surrounding forearm is called tennis
elbow and tendonitis
at the heel is called Achilles tendinitis. Tendinitis is common
in athletes who repeat a particular motion as part of a sport,
such
as tennis.
Tendinitis may be
treated at home, with the help of a sports medicine specialist
or physical therapist or with guidance from your healthcare
provider, if necessary. Mainly, rest and avoidance of the activity
that produced the injury are the first steps in treatment for
tendinitis. Ice may also help to reduce the inflammation and
pain associated
with tendinitis.
Physical therapy is often a useful choice to
treat tendinitis because it can relax the joints and build up
movement that will
eventually
allow a patient to get back to normal activity levels. If
tendinitis is severe, a provider may prescribe corticosteroids to
help with
inflammation. Otherwise, rest, ice, elevation and avoidance
are the keys to treating tendinitis.

Tension
Headache
A tension headache is felt behind the eyes, across the forehead
or over the top of the head – and has been described as “tight” and “gripping” among
other terms. The headache may interfere with the
patient’s
ability to concentrate or to sleep.
A tension headache is characterized
by pain that is constant and dull in both sides of the head.
Tight muscles in the head,
neck and
scalp due to stress, depression, anxiety, changes in temperature,
sleeping position or poor posture may cause a tension headache.
The
tension headache differs from the migraine, which
is a more severe, throbbing and localized pain. Headaches are often
a symptom of other conditions, but tension headaches occur on
their
own as the consequences of tension build up in the head, neck
and face. Sometimes, a healthcare provider may order a diagnostic
test, such as
a CT scan, to rule out the possibility of a more serious condition
causing the headache.
A tension headache may be treated with pain
relief medication, stress management and relaxation techniques,
the avoidance of headache-inducing
situations and positions, and additional therapy. Because tension
headaches are often related to outside stresses, anxiety or depression,
it is sometimes helpful to identify the cause and seek the necessary
therapy. Please note that this material is provided

Tetanus
Other name: Lockjaw
Tetanus is a disease caused by a poison that
is produced by bacteria. The bacteria enter the body through
an injury or wound
and produce
the poison that affects the central nervous system. This poison
can ultimately lead to death. The best way to prevent tetanus
is to keep
your tetanus vaccination up to date.
Tetanus causes nerves and
muscles to spasm and become rigid or tense. Once tetanus has
been contracted, symptoms may develop
in one to three weeks. Symptoms include:
- Stiffness in the jaw and neck
- Pain and tingling at the site of
the infection
- Difficulty swallowing
- Irritability
- Convulsions
- Difficulty breathing
Diagnosis of tetanus is based on the symptoms and
the physical
examination. Treatment usually includes antibiotics and tetanus
immune globulin. In some cases, sedatives will also be prescribed.
Those
being treated for tetanus also need careful monitoring to
ensure they don’t stop breathing or go into heart failure.
In the past, an estimated 40 percent of those diagnosed with tetanus
died, but today only about 5 tetanus-related deaths occur
in the
US each year. Even after treatment, those diagnosed with tetanus
should receive regular immunizations to prevent it from developing
in the future. Please note that this material is provided

Thyroid Cancer
Thyroid cancer is an abnormal growth of cells that forms in the
thyroid gland, which is a butterfly-shaped gland in the front
of the neck.
This gland generates hormones that control the body’s heart
rate, blood pressure, temperature and metabolism.
Thyroid cancer
is extremely rare. Few cases of thyroid cancer are serious,
and the ones that are tend to be slow-growing and
not fatal.
Risk factors, which are not causes of the disease but
are common factors among those who have been diagnosed
with it, include
being
exposed to radiation, having a family history of thyroid cancer
and being 40 years of age or older. Symptoms include:
- A lump in the side of the neck
- Hoarse voice
- Difficulty swallowing
- Pain in the throat or neck
A diagnosis of thyroid cancer is made
based on the results of a biopsy.
Treatment for thyroid cancer varies based on factors such
as how far the disease has progressed and the overall health
of the patient.
Treatment may include surgical removal of part or all of the
thyroid, radioactive iodine, hormone treatment, radiation therapy
or chemotherapy.

Thyroid Nodules
Thyroid nodules are lumps that occur within normal thyroid glands.
The nodules tend to be located along the edge of the thyroid
gland so they can be felt by feeling of one’s neck.
Most thyroid nodules are not cancerous, and some
are actually fluid-filled cysts rather than thyroid tissue.
Thyroid nodules
occur more frequently
among women than men, but the incidence of cancerous nodules
is greater among men.
Most thyroid nodules cause no symptoms,
but are usually found by patients who notice the lump in a mirror
or feel it in their
neck.
Physicians sometimes find nodules during a routine exam.
Diagnosis
of a thyroid nodule usually includes a fine needle aspiration
biopsy to determine if a nodule is cancerous. At times,
an ultrasound,
blood tests and thyroid function tests may also be required.
Some
healthcare providers may recommend treatment with a thyroid hormone
medication to reduce the size of the nodule. Other providers
are reluctant
to recommend this medication, since some nodules shrink on
their own without medication, and the medication may also cause osteoporosis
or heart disease. Cancerous nodules are most often surgically
removed.

Tinea Corporis
Other names: Ringworm of the body, tinea circinata, tinea of the
body, fungal infection of the body
Tinea corporis is a common
fungal infection of the skin. Small, red spots that grow into
large rings on the arms, chest and legs
are
characteristic of this condition.
Tinea corporis is contagious and
is passed by direct contact with those affected or by contact
with contaminated items such as bedding,
clothing, showers, combs and pool surfaces. Household pets infected
with the fungus also may spread it. Symptoms include:
- Itching of the affected area
- Rash
Diagnosis is primarily based on the appearance of the skin. A KOH
test or skin lesion biopsy may also be ordered by a healthcare provider
to
verify the diagnosis.
Treatment requires keeping skin clean and
dry and using over-the-counter antifungal creams. In severe cases,
a provider may prescribe oral
antifungal medications. Tinea corporis usually responds well
to treatment and is cured in four to six weeks. It is often important
to continue
treatment for a week after the symptoms are gone to treat any
remaining
fungus that may not be apparent to the eye. While over-the-counter
medication may be sufficient for treating tinea corporis, you
may want to see your healthcare provider to ensure that the symptoms
are not being caused by a more serious condition.

Tinnitus
Other name: Ringing in the ear
Tinnitus refers to the ringing in
the ear that millions of Americans experience every day. Sometimes,
this ringing in the ear goes largely
unnoticed and is a “normal” part of a patient’s
day. At other times, tinnitus can seriously interfere with a patient’s
ability to concentrate or live comfortably. Tinnitus is generally
a natural part of the aging process—a symptom of hearing
loss that happens as the ear matures and nerve cells weaken and
die. Tinnitus
is also commonly caused by acoustic trauma, or exposure for a
period of time to loud sounds that damage nerve cells.
Tinnitus can
be a symptom of a variety of diseases and conditions,
particularly different types of hearing loss, as well as otosclerosis,
hypertension and Menière’s disease. Tinnitus can also
be caused by problems with the jaw, particularly temporomandibular
disorder. Tinnitus may also be caused by something as minor as
slight earwax buildup or as a side effect of medications, specifically
many
types of antibiotics.
Most of the time, tinnitus will not interfere
with your life and is not a sign of a more serious health condition,
unless paired
with other symptoms. You should talk with your healthcare provider
if the ringing
becomes increasingly persistent, if you experience vertigo or
dizziness along with the tinnitus, if your hearing is impaired, or
if the
ringing becomes more severe and does not subside after two weeks.
You may be able to treat minor cases of tinnitus at home by avoiding
loud noises, meditating, cutting back on smoking and other stimulants,
limiting use of certain medications, exercising or carefully
cleaning the ear.
If tinnitus is associated with hearing loss, your provider
can help you deal with the symptoms by prescribing a hearing
aid,
or by
providing you with a masker, which is used at night to drown
out the ringing with subtle, relaxing drones that help induce sleep.
Unfortunately, if time doesn’t heal tinnitus caused by acoustic
trauma, or if tinnitus is age-related, it cannot be cured.

Tonsillitis
Tonsillitis is an infection or inflammation of the tonsils. Tonsils
are the lymph nodes located at the back of your mouth, which
keep bacteria and other foreign substances from entering the
body through
swallowing and breathing. If you are sick and your immune system
is slightly weakened, or if your tonsils become overloaded with
bacteria or virus, they may become infected themselves. A bacterial
or viral
infection will cause tonsillitis, and may be part of pharyngitis.
Symptoms of tonsillitis include:
- Swollen
tonsils
- Red tonsils
- White areas on tonsils
- Sore throat
- Tender jaw and throat
- Bad breath
- Headache
- Chills
- Fever
- Swollen lymph glands
- Loss of voice
- Voice change
Tonsillitis is usually diagnosed upon physical examination
and by looking at infected tonsils. A tonsil culture can help identify
the cause of
the infection.
Tonsillitis may be part of an infection of the throat, such as strep
throat. Many bacterial infections such as strep can be treated with
antibiotics.
If antibiotics are prescribed, you should be sure the cause is bacterial
before
you take the medication. When a virus causes tonsillitis, rest and drinking
plenty of fluids are recommended. Gargling with salt water is an oft-recommended
home remedy that helps soothe and heal infected tonsils. Throat lozenges
are also recommended for the pain. If tonsillitis becomes chronic or
problematic, especially in younger children, your healthcare provider
might recommend a tonsillectomy.
Be aware that the procedure becomes more complicated as you get older.

Tourette
Syndrome
Tourette syndrome is an inherited disorder that causes repeated, involuntary
body movements called tics and uncontrollable vocal sounds, which may
come and go over the years.
The cause of Tourette syndrome is unknown,
and many of those with the disorder also have other conditions such
as obsessive-compulsive disorder
or attention
deficit-hyperactivity disorder. People who suffer from Tourette syndrome
may try to control their tics, but often this is not possible. Tics
seem to worsen
in stressful situations and improve when a person is relaxed or absorbed
in activity. Symptoms of Tourette syndrome, which usually appear before
the age of 18, include:
- Eye blinking
- Nose twitching
- Head jerking
- Neck stretching
- Foot tapping
- Body twisting and bending
- Throat clearing
- Coughing
- Sniffing
- Barking, yelping, grunting or shouting
Tourette syndrome is generally
diagnosed by reviewing symptoms and family history and an MRI,
EEG or CT scan may be ordered. Certain blood
tests may be
conducted to rule out other possible causes. The medical rule of thumb
is that tics must be present for at least a year to be diagnosed as
Tourette syndrome.
Since most of those diagnosed with Tourette syndrome lead normal,
productive lives, treatment is not usually required. Medications are
available
to relieve some symptoms when severe or tics when they are frequent.
Many
people find
that the disorder improves as they get older.

Toxic
Shock Syndrome (TSS)
Toxic shock syndrome is a fairly rare but potentially
life-threatening condition that most often affects women of
childbearing age. TSS
is caused when toxic substances produced by specific bacteria
enter the bloodstream.
TSS was primarily associated with tampon use in
the 1970s and 1980s. Today, TSS is not
as prevalent because most tampons are now made from
natural fibers. Still, more than half of the cases diagnosed
today
are related
to tampon use. To avoid contracting TSS, change tampons regularly. Symptoms include:
- Diarrhea
- Vomiting
- Fever
- Headache
- Sore throat
- Muscle aches
- Rash
- Low blood pressure
- Kidney failure
- Heart failure
Diagnosis of TSS usually includes blood tests and a pelvic
exam to rule out sexually transmitted diseases. Treatment of TSS includes
the prompt removal
of a tampon, if one is being used, and cleansing the vagina with antiseptic
to remove the bacteria producing the toxin. Antibiotics and other medications
may be prescribed. Your physician may also recommended IV fluids and hospitalization
so that you may be carefully monitored. Please note that this material is provided

Transient
Ischemic Attack
Other names: Warning stroke, mini-stroke
A transient ischemic
attack occurs when blood flow to the brain is briefly
interrupted. Recognizing and treating TIAs helps
reduce
the risk of a stroke.
Most strokes are not preceded by TIAs, but
about one-third of those who have TIAs will have a stroke within
five years. Many strokes
can be prevented by addressing factors such as high blood pressure,
smoking, heart disease, diabetes, heavy alcohol use and carotid
artery disease. With proper medical attention and lifestyle changes
these
factors can be reduced or eliminated. Most TIAs only last one
to five minutes and do not cause injury to the brain. Symptoms, which
are similar to a stroke but do not last as long, include:
- Numbness on one side of face or body
- Confusion
- Difficulty speaking or comprehending
- Problems with balance and
coordination
Diagnosis includes a review
of one’s medical history, a physical
exam, and a CT scan or MRI. A carotid ultrasound, which is a procedure
used to examine blood flow, may also be recommended.
Treatment
may vary based on the cause of the TIA. Initially, your physician
will probably prescribe medication for this condition.
Those who do not respond to medication may require surgery.
Determining the difference between the symptoms of a TIA and
actual stroke is impossible, so it is best to seek emergency
medical care within an hour to determine if a TIA or stroke occurred.

Traveler’s
Diarrhea
Other names: Montezuma’s revenge, Tut’s tummy
Traveler’s
diarrhea is a common affliction that affects travelers to certain
countries that have different sanitation and climate conditions
from those to which they are accustomed. The most high-risk areas
for traveler’s diarrhea include Africa, the Middle East,
Asia and Latin America. Traveler’s diarrhea usually occurs
during a trip to a foreign country, although it may occur shortly
after
a return home. Traveler’s diarrhea is caused by consumption
of water or food contaminated with feces or other bacteria, particularly
E. coli, as well as viruses and parasites.
Traveler’s diarrhea
is characterized by these symptoms:
- Loose
stools
- Frequent bowel movements
- Cramps
- Vomiting
- Nausea
- Bloating
- Fever (sometimes)
- Dehydration
- Malais
Traveler’s diarrhea usually will clear up without treatment
after approximately one week, but it may last up to a month. Treatment
involves mainly “waiting
it out” with self-care measures and the possibility of taking antimotility
medications, which can provide gastrointestinal relief. If you have a fever
or bloody diarrhea, you should see a healthcare professional for further
testing, which can be difficult in foreign countries.
Prevention is highly recommended for
travelers to any foreign countries where there may be a chance of contracting
traveler’s diarrhea. Preventive
measures include:
- Avoid all tap water for everything—including brushing
your teeth and ice
- Boil all tap water if you must use it
- Drink pasteurized milk
- Avoid raw fruits and vegetables, raw or
rare meats, shellfish
- Do not buy food from street vendors
- Wash hands constantly
- Make sure all dishes and utensils are
clean

Trichomoniasis
Trichomoniasis is the most common curable sexually transmitted
disease in young, sexually active women – an estimated 5 million
new cases are
diagnosed
each year. It usually
affects women, but men can be carriers without exhibiting any symptoms.
Trichomoniasis
is spread through penis-to-vagina intercourse or vulva-to-vulva
contact with an infected person. Symptoms tend to appear in women within
28 days of being infected. Symptoms, which often are not present,
include:
- A smelly, yellow vaginal
discharge
- Itching
- Burning
- Redness
Diagnosis includes a physical examination and diagnostic
tests. A physician may find small red sores on the vaginal wall when
conducting
a pelvic exam.
Trichomoniasis may be cured with prescription medications, but
both partners should be treated to prevent further infection and spread
of the disease. Please note that this material is provided

Trigeminal
Neuralgia
Other name: Tic douloureux
Trigeminal neuralgia is a rare neurological
disorder that causes pain in areas of the face where branches of the
fifth cranial nerve,
also called
the trigeminal nerve, are located. This condition is not fatal but
is widely considered one of the most painful disorders known. Something as
simple
as even
a breeze can cause agonizing pain among those who suffer from TN.
Another
form of TN is called atypical TN, which may cause less severe but constant
pain in the face. Both forms of TN usually only affect one
side
of the face
during any given episode. Pain may last for days, weeks or months and
then not recur for extended periods of time. Onset of TN symptoms may
occur
at any age, but usually occur after the age of 50. Symptoms include:
- Intense
pain in the lips, eyes, scalp, forehead and jaw
- Stabbing or shock-like
sensation
TN may be caused by pressure on the blood
vessel on the root of the trigeminal nerve, plaque that results due
to MS, pressure of a tumor on the trigeminal
nerve, damage caused by dental work or surgery. Any number of activities,
such as eating, shaving, applying makeup or even talking, may trigger
an attack
of TN.
Treatment usually includes the use of anti-convulsant and anti-depressant
drugs. In cases where drug therapy is ineffective, relief may be provided
by some neurosurgical procedures as well as alternative treatments
such as acupuncture and hypnosis.

Trigger Finger
Other name: Stenosing tenosynovitis
Trigger finger is the swelling
and inflammation of the tendons that connect the muscles of
the forearm to the finger bones and
that control
the bending and extending motion of the fingers. With trigger
finger, the tendons become so irritated and inflamed that the finger
remains bent in a trigger-pulling position. Trigger finger is common
in
patients who have rheumatoid arthritis
or diabetes.
Trigger finger may also affect the thumb. Trigger finger may
be caused by a repetitive use of the finger, such as that performed
by musicians,
typists or industrial workers.
Trigger finger can be easily diagnosed
by simply examining the finger and hand. Treatment will reduce
irritation and inflammation
through
rest, pain relief medication, a splint for support and avoidance
of any aggravating activities. For more severe cases of trigger
finger, a steroid injection may help the healing process. The
condition becomes
more severe in patients who have had rheumatoid arthritis or
diabetes and may require surgery.

Tuberculosis
(TB)
Other name: Consumption
Tuberculosis is a potentially fatal disease that primarily affects
the lungs. It can be treated, cured and prevented, if those at risk
take certain medication. More than 8 million new cases are diagnosed
worldwide each year.
Those at a high risk of contracting TB include the elderly, certain
ethnic groups, those infected by the HIV, alcoholics and IV drug
users. TB also can affect other parts of the body, such as the bones,
kidneys, spine, brain, the abdominal cavity and joints.
Tuberculosis is spread when a TB patient exhales, coughs or sneezes
and droplets containing the bacteria are released into the air and
inhaled by others. However, unlike other infections, TB is not transmitted
by contact with a patient’s clothing, dishes or bed linens.
Symptoms of TB may include:
- Cough
- Low-grade fever
- Difficulty breathing
- Loss of appetite
- Weight loss
Diagnosis of TB is based on a TB skin test and other diagnostic
tests such as a chest X-ray, a test of a sputum sample and a urine
test. TB is usually treated with prescription medications. Hospitalization
is rarely necessary. Most of those diagnosed with TB today make a
full recovery if the disease is diagnosed early and treated with
appropriate medications for six months.
