Cardiomyopathy

Cardiomyopathy changes the heart's shape, making it harder to pump blood.

What is Cardiomyopathy?
It is a disease of the heart muscle (myocardium) that makes it harder for the heart to pump blood to the rest of the body.

The Result: It often leads to Heart Failure.

The 3 Main Types

Type	What Happens to the Heart?	Who is at Risk?
Dilated (Most Common)	The muscle becomes thin and stretched (like an overblown balloon). It pumps weakly.	Middle-aged adults, often due to coronary artery disease.
Hypertrophic	The muscle becomes abnormally thick and stiff. The pumping chamber shrinks.	Often genetic. Can affect young athletes.
Restrictive	The muscle becomes rigid/stiff (like scar tissue). It can't relax to fill with blood.	Older adults; rare.

⚠️ WARNING: YOUNG ATHLETES
Hypertrophic Cardiomyopathy (HCM) is a leading cause of sudden cardiac arrest in young people and athletes. It often has no symptoms until a fatal event.
Screening: If you have a family history of sudden death, get screened before playing competitive sports.

Symptoms

In early stages, you may have no symptoms. As the heart weakens, signs of heart failure appear:

Breathlessness: Especially during exertion.
Swelling (Edema): In legs, ankles, and feet.
Fatigue: Feeling tired all the time.
Palpitations: Rapid, fluttering heartbeats.

Causes

Genetics: Inherited from parents.
Long-term High Blood Pressure: Forces the heart to work too hard.
Heart Attack Damage: Scar tissue weakens the muscle.
Alcohol/Drugs: Long-term alcohol abuse or cocaine use.
Viral Infections: Can inflame the heart muscle.

Diagnosis

The main test is an Echocardiogram (Echo). This ultrasound shows the heart's movement and measures the Ejection Fraction (how much blood is pumped out).

Treatment

Treatment depends on the type but generally focuses on managing heart failure symptoms.

1. Medications

ACE Inhibitors / Beta Blockers: Lower blood pressure and slow heart rate to reduce workload.
Diuretics (Water Pills): Reduce fluid buildup.
Blood Thinners: To prevent clots, as sluggish blood flow increases clot risk.

2. Devices & Surgery

ICD (Implantable Cardioverter-Defibrillator): A device that shocks the heart if it detects a dangerous rhythm (vital for HCM patients).
Septal Myectomy: Surgery to remove part of the thickened muscle in Hypertrophic Cardiomyopathy.
Heart Transplant: For severe, end-stage cases.

Lifestyle Management

Limit Salt: Aim for under 1,500mg daily to prevent fluid retention.
Weigh Yourself Daily: A sudden gain of 2-3 lbs in a day is a sign of fluid buildup.
Avoid Alcohol: It is toxic to the heart muscle.

What is a Cataract?
A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil.

The Analogy: Imagine looking through a foggy or frosted window. Things look blurry, hazy, and less colorful. It is not a growth on the surface of the eye, but a change inside the lens itself.

Symptoms: The Gradual Fade

Cataracts usually develop slowly and painlessly. Watch for these changes:

Cloudy/Blurred Vision: Like looking through a dirty camera lens.
Night Trouble: Difficulty driving at night due to glare.
Halos: Seeing bright rings around streetlights or headlights.
Faded Colors: Colors may look yellowed or washed out.
Double Vision: Seeing double in just one eye.

Types of Cataracts

The symptoms depend on which part of the lens is clouding over.

Type	Location	Key Symptom
Nuclear Sclerotic	Center of the lens.	Nearsightedness improves briefly ("Second Sight"), then vision yellows/browns.
Cortical	Edges of the lens (Wedge shapes).	Problems with glare; light streaks scatter across vision.
Posterior Subcapsular	Back of the lens.	Progresses faster. Causes severe glare and difficulty reading.

Causes & Risk Factors

Aging: The most common cause. Proteins in the lens break down and clump together.
Diabetes: High blood sugar damages the lens.
UV Exposure: Excessive sunlight without sunglasses.
Steroids: Long-term use of corticosteroid medications.
Smoking: Increases risk significantly.

Treatment: Cataract Surgery

Surgery is the only way to remove a cataract. It is one of the most common and safest surgeries in the world.

ℹ️ WHEN TO HAVE SURGERY?
You do not need to rush. Surgery is only recommended when your vision loss interferes with your daily life (e.g., you can't drive safely, read, or watch TV).

The Procedure (Phacoemulsification)

Numbing: The eye is numbed with drops. You are awake but feel no pain.
Removal: The surgeon makes a tiny incision. An ultrasound probe breaks up the cloudy lens and suctions it out.
Replacement: An artificial Intraocular Lens (IOL) is inserted. This lens is permanent and requires no care.

Complications

If untreated for too long, a cataract can become "Hyper-Mature" (completely white), which can cause inflammation or glaucoma and is harder to remove surgically.

Secondary Cataract: Months or years after surgery, the membrane holding the new lens may become cloudy. This is easily fixed with a quick, painless laser procedure (YAG Laser).

Prevention & Lifestyle

Wear Sunglasses: Block UV rays to slow progression.
Quit Smoking: Smoking speeds up lens degeneration.
Eat Antioxidants: Leafy greens and fruits may promote eye health.
Brighter Lights: Use brighter lamps for reading if you aren't ready for surgery yet.

Chickenpox

The tell-tale sign of Chickenpox: An itchy rash that turns into fluid-filled blisters.

What is Chickenpox?
Chickenpox (Varicella) is a highly contagious viral infection that causes an itchy, blister-like rash.

The Virus: It is caused by the Varicella-Zoster virus. Once you have it, the virus stays dormant in your body and can return years later as Shingles.

The 3 Stages of the Rash

The rash appears 10–21 days after exposure. It evolves in three distinct phases, often with new bumps appearing while old ones heal.

Stage 1: Papules (Days 1-2). Raised pink or red bumps break out.
Stage 2: Vesicles (Days 2-4). The bumps turn into small, fluid-filled blisters (vesicles) that eventually break and leak.
Stage 3: Crusts (Days 4+). The broken blisters dry up and form scabs.

🛑 THE "SCHOOL RULE": WHEN IS IT CONTAGIOUS?
You can spread the virus from 48 hours before the rash appears until every single blister has crusted over.

Do not return to school or work until no new spots have appeared for 24 hours and all old spots are dry scabs.

How it Spreads

[Image of varicella-zoster virus transmission]

Chickenpox is airborne and contact-based. You can catch it by:

Breathing: Inhaling droplets from an infected person's cough or sneeze.
Touching: Touching the fluid from a broken blister.

⚠️ DANGER: NO ASPIRIN
NEVER give Aspirin (or products containing aspirin) to children or teenagers recovering from Chickenpox or flu-like symptoms.

Why? It has been linked to Reye's Syndrome, a rare but fatal condition that causes severe liver and brain damage. Use Acetaminophen (Tylenol) instead.

Treatment: Managing the Itch

For healthy children, Chickenpox just needs to run its course. Treatment focuses on relief:

1. Stop the Itch

Oatmeal Baths: Use colloidal oatmeal (finely ground) in a cool bath to soothe skin.
Calamine Lotion: Dab on spots (but avoid the eyes).
Antihistamines: Oral meds like Benadryl can reduce itching and help with sleep.

2. Prevent Infection

Scratching can cause bacterial infections (like Staph). Trim fingernails short and consider putting gloves/socks on children's hands at night.

Prevention: The Vaccine

The best way to prevent Chickenpox is the Varicella Vaccine.

Dose 1: Ages 12–15 months.
Dose 2: Ages 4–6 years.

Note: Vaccinated children can still get Chickenpox ("Breakthrough Infection"), but it is usually very mild with fewer than 50 spots.

The Long-Term Link: Shingles

After Chickenpox heals, the virus goes to sleep in your nerve roots. Decades later, stress or a weakened immune system can wake it up, causing Shingles (Herpes Zoster)—a painful rash that usually appears as a single stripe on one side of the body.

What is Hypothermia?
Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce it.

The Danger Zone: Normal body temperature is 98.6°F (37°C). Hypothermia begins when the body temperature drops below 95°F (35°C). At this point, the heart and nervous system begin to fail.

Symptoms: Watch for the "Umbles"

Hypothermia affects the brain, making the victim confused. They often do not realize they are in danger. Watch for the "Umbles":

Stumbles: Loss of coordination, clumsiness.
Mumbles: Slurred speech.
Fumbles: Slow reaction time, dropping items.
Grumbles: Change in personality, irritability, or apathy.

Stages of Severity

Stage	Key Symptom	Status
Mild	Shivering heavily. Alert but confused.	Urgent.
Moderate	Shivering STOPS. Confusion increases.	Critical Danger.
Severe	Unconsciousness. Weak/irregular pulse. Paradoxical undressing (victim feels hot and takes off clothes).	Life Threatening.

🚑 WHEN TO CALL 911
If a person’s temperature is below 95°F, or if they have stopped shivering and seem confused/drowsy, call for emergency help immediately.

First Aid: Critical Do's and Don'ts

Treating hypothermia incorrectly can cause cardiac arrest. Follow these rules carefully while waiting for help.

✅ DO THIS:

Be Gentle: Move the person slowly. Jarring movements can trigger a heart attack.
Remove Wet Clothing: Cut it off if necessary to avoid moving them too much.
Layers: Cover them with dry blankets (including the head).
Skin-to-Skin: If necessary, use your own body heat to warm them.
Warm Sweet Drinks: Only if they are fully conscious and able to swallow.

❌ STOP! DO NOT DO THIS:

DO NOT Rub or Massage: Do not rub their arms or legs. This pushes cold blood from the limbs back to the heart, which can cause heart failure (The "Afterdrop" Effect).
DO NOT Use Hot Water: Do not put them in a hot bath. It warms them too fast and can cause shock.
DO NOT Give Alcohol: It dilates blood vessels and makes heat loss worse.
DO NOT Use Heating Pads on Arms/Legs: Apply heat only to the chest, neck, or groin.

Causes & Vulnerable Groups

You don't have to be on Mount Everest to get hypothermia. It can happen indoors.

The Elderly (Indoor Risk): Older adults lose the ability to regulate body temperature. A poorly heated house (below 65°F) can trigger hypothermia in seniors.
Infants: They lose heat faster than adults. (Symptoms: Bright red, cold skin, and low energy).
Alcohol Use: Alcohol makes you feel warm but actually causes your body to lose heat rapidly.
Water Immersion: Water draws heat away from the body 25x faster than air.

Prevention: The "C.O.L.D." Rule

C - Cover: Wear a hat. 30-50% of body heat is lost through the head.
O - Overexertion: Avoid activities that make you sweat excessively. Wet clothes + cold air = danger.
L - Layers: Wear loose, lightweight layers. Wool or synthetic materials are better than cotton.
D - Dry: Stay dry. Change out of wet clothes immediately.

What is the Common Cold?
The common cold is a viral infection of your nose and throat (upper respiratory tract).

Key Fact: It can be caused by over 100 different viruses (Rhinovirus is the most common). Because there are so many variations, you can catch colds repeatedly throughout your life.

Is it a Cold or the Flu?

The symptoms often overlap, but the intensity is different. Use this guide:

Symptom	Common Cold	The Flu (Influenza)
Onset	Gradual (over days).	Sudden (hits like a truck).
Fever	Rare or mild.	High (100°F - 102°F+).
Aches	Slight.	Severe muscle aches.
Energy	Mild fatigue.	Extreme exhaustion (can last weeks).
Sneezing	Common.	Sometimes.

⚠️ WHEN TO SEE A DOCTOR
Adults: Fever > 103°F (39.4°C) or severe sinus pain.
Children:

Newborns (< 12 weeks): Any fever > 100.4°F.
Difficulty Breathing: Wheezing or rapid breathing.
Dehydration: Urinating less often than usual.
Ear Pain: Persistent crying or pulling at ears.

Causes & Transmission

Viruses enter through your mouth, eyes, or nose. You catch it by:

Droplets: Someone coughs or sneezes nearby.
Direct Contact: Shaking hands with an infected person.
Fomites: Touching contaminated objects (doorknobs, toys, phones) and then touching your face.

🛑 ANTIBIOTICS DO NOT WORK
Myth: "I need antibiotics to knock this cold out."
Fact: Colds are caused by Viruses. Antibiotics only kill Bacteria. Taking them for a cold will not help you get better and may cause side effects or antibiotic resistance.

Treatment: The Science of Comfort

There is no cure, but you can manage the misery. Most colds last 7–10 days.

1. Honey (Nature's Cough Syrup)

Studies suggest honey can be as effective as cough syrup for children. Give 1/2 to 1 teaspoon as needed. (Note: Never give honey to infants under 1 year due to botulism risk).

2. Chicken Soup

It’s not just an old wives' tale. Science suggests chicken soup may:

Act as a mild anti-inflammatory.
Speed up the movement of mucus (clearing congestion) thanks to the warm steam.

3. Saline Drops & Humidifiers

Use a cool-mist humidifier to keep nasal passages moist. For infants, use saline drops and a bulb syringe to clear a stuffy nose before feeding.

4. Medications (OTC)

Pain Relievers: Acetaminophen (Tylenol) or Ibuprofen (Advil) for aches/fever. Never give Aspirin to children/teens.
Decongestants: Use nasal sprays for max 3 days to avoid "rebound congestion."

Prevention

Wash Hands: Ideally for 20 seconds.
Don't Share: Keep your cups and utensils to yourself.
Sanitize: Wipe down high-touch surfaces like remotes and phones.

Consciousness is controlled by the Reticular Activating System (RAS) in the brainstem. Damage here often leads to coma.

What is a Coma?
A coma is a state of prolonged unconsciousness. The person is alive but cannot be awakened and fails to respond normally to painful stimuli, light, or sound.

The "Sleep" Myth: Unlike sleep, a person in a coma cannot be woken up. It is the brain's way of shutting down high-level functions to focus solely on keeping the heart and lungs working after a trauma.

🚑 MEDICAL EMERGENCY
Coma is a life-threatening emergency. Swift action is needed to preserve brain function.
Call 911 immediately if you find someone unconscious who cannot be roused.

Signs & Symptoms

Doctors look for specific involuntary reflexes to determine the depth of the coma:

Closed Eyes: The patient appears to be sleeping.
No Response: Limbs do not move voluntarily, though reflexes (twitching) may happen.
Pupils: May not react to light (fixed pupils).
Irregular Breathing.

Doctors check for "Posturing"—rigid body positions that indicate severe brain damage.

Common Causes

Traumatic Brain Injury (TBI): Car accidents or blows to the head.
Stroke: Lack of blood flow kills brain cells.
Diabetes: Blood sugar that is too high (Hyperglycemia) or too low (Hypoglycemia).
Lack of Oxygen (Anoxia): Drowning or heart attack resuscitation.
Toxins: Overdose of drugs, alcohol, or carbon monoxide poisoning.

Diagnosis: The Glasgow Coma Scale

Doctors rate the severity of a coma using a point system called the Glasgow Coma Scale (GCS). The score ranges from 3 to 15.

Score	Severity
13 - 15	Mild Brain Injury (Concussion).
9 - 12	Moderate Injury.
8 or less	Severe Coma. (Doctors often say, "Less than 8, intubate," meaning the patient needs a machine to breathe).
3	Deep Coma or Death.

Understanding the Outcomes

Coma rarely lasts longer than a few weeks. Patients usually transition into one of these states:

State	Description
Vegetative State	The person may have open eyes and sleep-wake cycles, but has no awareness of surroundings.
Minimally Conscious	Occasional signs of awareness (e.g., following a finger with eyes or squeezing a hand on command).
Brain Death	Irreversible cessation of all brain activity. The person is legally dead, though machines may keep the heart beating.
Locked-In Syndrome	(Rare) The person is fully awake and aware but completely paralyzed and cannot speak or move.

Family Support & Complications

Since the patient cannot move, family and nursing care is vital to prevent secondary complications:

Bedsores (Pressure Ulcers): The patient must be turned every few hours to prevent skin death.
Muscle Contractures: Physical therapy (moving the limbs) helps prevent muscles from shortening and freezing in place.
Infections: Pneumonia and bladder infections are common risks due to immobility and catheters.

Vocal cord paralysis

Vocal cords must close tightly to produce sound and keep food out of the lungs. Paralysis prevents this closure.

What is Vocal Cord Paralysis?
It occurs when the nerve impulses to your voice box (larynx) are interrupted. One or both of the vocal cords become unable to move.

The Dual Function: Vocal cords do two things:

Speak: They vibrate to make sound.
Protect: They close tightly when you swallow to stop food/water from entering your windpipe.

Symptoms

Symptoms depend on whether the cord is paralyzed in the "open" or "closed" position.

Breathy Voice: You sound like you are whispering because air leaks through the gap.
Hoarseness: A raspy or strained quality.
Noisy Breathing: (Stridor) if the cords are paralyzed in a closed position.
Ineffective Cough: You cannot clear your throat properly.

One vs. Both Cords

Type	Severity	Main Issue
Unilateral (One cord paralyzed)	Common	Voice & Swallowing. The working cord tries to compensate for the paralyzed one.
Bilateral (Both cords paralyzed)	Medical Emergency	Breathing. If both cords are paralyzed in a "closed" position, they block the airway. This often requires a Tracheotomy.

⚠️ DANGER: ASPIRATION
Because the vocal cords cannot close tightly, food or liquid may slip into the lungs instead of the stomach.
Watch for: Choking or coughing every time you drink water. This can lead to Aspiration Pneumonia, a severe lung infection.

Causes

Surgery (Most Common): Accidental damage to the recurrent laryngeal nerve during Thyroid or neck surgery.
Tumors: Growths in the neck or chest pressing on the nerves.
Viral Infections: Inflammation from viruses (like Lyme disease or West Nile) can damage the nerves.
Stroke: Damage to the brain area that controls muscles.

Diagnosis

An ENT (Ear, Nose, Throat) doctor will look down your throat using a:

Laryngoscopy: A thin flexible tube with a camera is passed through the nose to watch the cords while you speak.
Laryngeal EMG: Measuring electrical currents in the voice box muscles to check for nerve damage.

Treatment Options

Doctors often wait 6–12 months before permanent surgery, as nerves can sometimes heal on their own.

1. Voice Therapy

Exercises to strengthen the vocal cords and teach the "good" cord to compensate for the paralyzed one.

2. Surgical Options

Bulk Injection: The doctor injects a filler (like collagen or body fat) into the paralyzed cord. This "plumps" it up, making it easier for the other cord to touch it and close the gap.
Thyroplasty (Implant): Placing a small implant in the voice box to permanently push the paralyzed cord into the center.
Tracheotomy: Used only in severe bilateral cases to create a new airway for breathing.

Lifestyle & Coping

Tuck Your Chin: When swallowing, tuck your chin to your chest. This mechanical position helps close the airway and prevent choking.
Humidify: Keep the air moist to prevent the vocal cords from drying out.
Voice Amplifiers: Use a microphone if you have to speak to groups, to prevent straining.

Vaginitis is an inflammation caused by an upset in the natural balance of bacteria or by an infection.

What is Vaginitis?
Vaginitis is not a single disease, but a general term for inflammation of the vagina. It results in discharge, itching, and pain.

The Cause: Usually a disruption in the normal balance of healthy bacteria (microbiome) or an infection.

The "Discharge Decoder"

The type of discharge is your biggest clue. Use this guide to help identify what might be wrong:

Symptoms	Color/Texture	Smell	Likely Cause
Intense itching, burning.	Thick, White (Like Cottage Cheese)	None (or yeasty/bread-like).	Yeast Infection (Candida)
Mild itching, burning.	Thin, Gray or White	Fishy Odor (Worse after sex).	Bacterial Vaginosis (BV)
Painful urination, redness.	Yellow-Green (Frothy/Bubbly)	Foul / Unpleasant.	Trichomoniasis (Parasite)
Dryness, pain during sex.	None / Slight spotting	None.	Atrophy (Low Estrogen)

🛑 STOP DOUCHING
Myth: "I need to clean inside to get rid of the infection."
Fact: Douching flushes out healthy bacteria (Lactobacillus) that fight infection. It upsets the pH balance and makes Vaginosis worse. Your vagina is self-cleaning; leave the internal cleaning to your body.

The Main Causes

1. Bacterial Vaginosis (BV)

The most common vaginal infection. It happens when "bad" bacteria outnumber the "good" bacteria. It is not technically an STD, but it is linked to new sexual partners.

2. Yeast Infections (Candida)

[Image of candida albicans under microscope]

Caused by a fungus causing an intense itch. Common triggers include antibiotic use (which kills good bacteria), pregnancy, or uncontrolled diabetes.

3. Trichomoniasis ("Trich")

A sexually transmitted infection (STI) caused by a microscopic parasite. Unlike BV or Yeast, this requires partner treatment.

4. Non-Infectious (Allergies/Atrophy)

Caused by scented soaps, detergents, or a drop in estrogen during menopause (thinning walls).

Diagnosis

Doctors use a simple swab test to check pH levels and look at cells under a microscope.

Whiff Test: Checking for a fishy odor when a special solution is added to the sample (indicates BV).
pH Test: Normal vaginal pH is 3.8–4.5. Higher pH suggests BV or Trich.

Treatment & Partner Care

Note: Using leftover medication from a previous infection is dangerous because treating the wrong thing (e.g., using yeast cream for BV) can make it worse.

Condition	Treatment	Does Partner Need Meds?
Yeast	Antifungal Cream (Monistat) or Oral Pill (Diflucan).	No (Unless they have symptoms).
BV	Antibiotics (Metronidazole) Gel or Pills.	Generally No (For male partners).
Trichomoniasis	Antibiotics (Metronidazole).	YES. Must be treated to prevent reinfection.

Prevention Tips

Cotton Underwear: Breathable fabric prevents moisture buildup (yeast loves moisture).
Skip Scented Products: Avoid scented pads, tampons, and soaps.
Wipe Front to Back: Prevents transferring rectal bacteria to the vagina.

Vaginal dryness

A decline in estrogen causes vaginal walls to become thinner, drier, and less elastic (Atrophy).

What is Vaginal Dryness?
While often dismissed as a minor nuisance, vaginal dryness is a hallmark sign of Vaginal Atrophy (thinning and inflammation of the vaginal walls).

Key Insight: It is most common during menopause due to dropping estrogen levels, but it can affect women of any age. It is a treatable medical condition, not just a "part of aging."

Symptoms

Dryness is just one symptom. The condition often presents as:

Itching or Stinging: Around the vaginal opening.
Dyspareunia: Pain or light bleeding during intercourse.
Urinary Issues: Frequent urgency or recurrent Urinary Tract Infections (UTIs).
Soreness: A feeling of rawness or burning.

Causes: The Estrogen Connection

Estrogen keeps vaginal tissue thick, elastic, and moist. When levels drop, that defense disappears. Common triggers include:

Menopause: The most common cause.
Breastfeeding & Childbirth: Temporary drops in estrogen.
Cancer Treatments: Chemotherapy or radiation to the pelvis.
Sjogren's Syndrome: An autoimmune disorder that attacks moisture-producing glands.
Medications: Allergy meds (antihistamines) dry out mucous membranes, including vaginal tissue.

Complications

⚠️ THE UTI CYCLE
Vaginal atrophy changes the pH balance of the vagina, making it easier for bad bacteria to grow. This is why many post-menopausal women suffer from Recurrent Urinary Tract Infections (UTIs). Treating the dryness often stops the infections.

Other complications include small tears (fissures) in the vaginal wall and a negative impact on sexual intimacy and relationships.

Treatment Options

Treatment is divided into non-hormonal (OTC) and hormonal (Prescription) options.

1. Non-Hormonal Options (The Difference)

Many women are confused by the products aisle. Here is the difference:

Vaginal Moisturizers	Vaginal Lubricants
Purpose: Maintenance. Usage: Used every few days (not just for sex) to keep tissue hydrated and healthy. Example: Replens, Hyalo Gyn.	Purpose: Sex. Usage: Used immediately before intercourse to reduce friction and pain. Example: Astroglide, KY Jelly.

2. Hormonal Options (Local Estrogen)

For moderate to severe cases, doctors prescribe low-dose vaginal estrogen. Unlike oral pills, these apply estrogen locally to the tissue, meaning very little is absorbed into the bloodstream.

Creams: Applied with an applicator (e.g., Estrace).
Tablets: Inserted like a tampon (e.g., Vagifem).
Rings: A soft ring inserted for 3 months that releases a steady dose (e.g., Estring).

Lifestyle & Prevention

Avoid Irritants: Stop douching. Avoid scented soaps, bubble baths, and lotions in the pelvic area.
Stay Active: Regular sexual activity (with a partner or alone) increases blood flow to the pelvic area, which helps maintain tissue health.
Foreplay: Allow more time for arousal to stimulate natural lubrication.

What is Typhoid Fever?
Typhoid is a systemic bacterial infection caused by Salmonella typhi. It spreads through contaminated food and water.

Key Characteristic: Unlike a standard stomach bug, Typhoid causes a high, sustained fever ("Step-Ladder Fever") that rises daily, along with severe weakness and abdominal pain.

The 4 Stages of Typhoid

Symptoms usually appear 1–3 weeks after exposure. They progress slowly if untreated.

Week 1: The Onset

Step-Ladder Fever: Starts low and rises daily, reaching 103–104°F (39–40°C).
Headache & Dry Cough.
Weakness: Extreme fatigue and muscle aches.
Abdominal Pain: With either constipation (adults) or diarrhea (children).

Week 2: The Rash & Pain

Rose Spots: Small, flat, pink spots may appear on the lower chest/abdomen.
Distended Abdomen: The stomach looks swollen and feels painful.
High Fever: Remains high and does not fluctuate much.

Week 3: The Danger Zone

If still untreated, this is the most critical week.

"Typhoid State": Lying motionless, half-asleep, and delirious.
Complications: Risk of intestinal bleeding or perforation.

Week 4: Recovery

The fever begins to drop gradually. Full recovery can take weeks.

⚠️ EMERGENCY: INTESTINAL PERFORATION
In the 3rd week, ulcers in the intestine can burst. This is life-threatening.
Seek immediate surgery if:

Sudden, excruciating stomach pain.
Rapid drop in blood pressure (Shock).
Blood in the stool (tarry/black stool).

Transmission: The F-Diagram

Typhoid spreads via the Fecal-Oral Route. This happens through:

Fluids	Drinking contaminated water or milk.
Food	Eating raw vegetables washed in dirty water or food handled by infected persons.
Fingers	Not washing hands after using the toilet.
Flies	Flies transfer bacteria from feces to food.

Diagnosis

Doctors look for the bacteria in your system. Be aware of the testing differences:

Blood Culture (Gold Standard): The most accurate test in the first week.
Widal Test: A common older test. Note: It often gives false positives, so do not rely on this alone without a doctor's interpretation.
Stool Culture: Useful in the 2nd or 3rd week.

Treatment

Typhoid is treated with antibiotics. You will usually feel better within 2–3 days of starting medication.

Antibiotics: Ciprofloxacin, Ceftriaxone, or Azithromycin.
Fluids: IV fluids may be needed for severe dehydration.

Warning on Resistance: Multi-Drug Resistant (MDR) Typhoid is becoming common. You must finish your full course of antibiotics even if your fever breaks, to prevent the bacteria from returning stronger.

The Typhoid Diet

Your intestine is inflamed and fragile. Eat soft, easily digestible foods.

🍽️ WHAT TO EAT vs. AVOID

EAT: Yogurt, boiled potatoes, porridge, white rice, coconut water, bananas, boiled eggs.
AVOID: Spicy food, high-fiber foods (whole grains, raw salads), fried items, and milk (if it causes bloating).

Prevention & Carriers

Vaccination: Available as an injection or oral capsule. Recommended for travelers to endemic areas (Asia, Africa, Latin America).
Chronic Carriers: Some people recover but still carry the bacteria in their gallbladder (like "Typhoid Mary"). They shed bacteria in their stool for years. If you have a history of Typhoid, wash hands rigorously before cooking for others.

Tuberculosis

What is Tuberculosis (TB)?
TB is a potentially serious infectious disease that mainly affects your lungs. It is caused by the bacterium Mycobacterium tuberculosis.

Key Fact: It spreads through the air when someone with active TB coughs or sneezes. It is not spread by shaking hands or sharing dishes.

The Two Forms of TB

You can have TB bacteria in your body without being sick. This distinction is vital:

Latent TB (Inactive)	Active TB (Disease)
Bacteria are "asleep" in the body. You feel healthy and have no symptoms. You are NOT contagious. Needs treatment to prevent it from waking up later.	Bacteria are multiplying and attacking the body. You feel sick and have symptoms. You CAN spread it to others. Needs immediate, aggressive treatment.

Symptoms of Active TB

TB usually attacks the lungs, but can affect the kidney, spine, or brain.

The Cough: Lasting 3 weeks or longer.
Hemoptysis: Coughing up blood or sputum (phlegm).
Chest Pain: Pain with breathing or coughing.
Night Sweats: Drenching sweats during sleep.
Unintentional Weight Loss.

🛑 CRITICAL WARNING: MDR-TB
You must finish your medication.

TB treatment takes 6 to 9 months. You will feel better after a few weeks, but the bacteria are still alive. If you stop taking the pills early, the surviving bacteria become Drug-Resistant (MDR-TB). This super-strain is much harder to kill and far more deadly.

Risk Factors

HIV/AIDS: HIV suppresses the immune system, making it the #1 risk factor for Latent TB waking up into Active TB.
Crowded Living: Prisons, shelters, or nursing homes with poor ventilation.
Global Travel: Visiting regions with high TB rates (Africa, Asia, parts of Eastern Europe).

Diagnosis

Doctors use a combination of tests to confirm infection:

Skin Test (Mantoux): A fluid is injected under the skin of the arm. A raised red bump after 48 hours indicates infection (Latent or Active).
Blood Test (IGRA): More accurate than the skin test; measures immune response.
Chest X-Ray: Shows white spots in the lungs where the immune system has walled off bacteria.
Sputum Test: Testing the mucus you cough up to see if it is drug-resistant.

Treatment

Treatment involves a long course of antibiotics. You will likely take a combination of these four drugs:

Isoniazid (INH)
Rifampin (Rifadin)
Ethambutol (Myambutol)
Pyrazinamide

What is DOT?

Directly Observed Therapy (DOT): Because finishing the meds is so critical for public safety, a health care worker may meet you daily to watch you swallow the pills. This isn't because they don't trust you; it's the standard of care to prevent drug resistance.

Lifestyle & Prevention

Isolation: If you have Active TB, stay home. Do not go to work or school until your doctor says you are no longer contagious (usually after a few weeks of treatment).
Ventilation: Open windows. TB bacteria hang in stagnant air but blow away in fresh air.
BCG Vaccine: Commonly given to infants in countries with high TB rates. It is rarely used in the USA. Note: This vaccine can cause a "False Positive" on a TB skin test.

What is Tonsillitis?
Tonsillitis is the inflammation of the tonsils, the two oval-shaped pads of tissue at the back of the throat.

Key Function: Tonsils are the immune system's "first line of defense" against germs entering the mouth. Because they trap germs, they can easily get infected themselves.

Symptoms

It most commonly affects children from preschool to mid-teens.

What You See

Red, swollen tonsils.
White or yellow coating/patches on the tonsils.
Swollen glands (lymph nodes) on the sides of the neck.

What You Feel

Severe Sore Throat.
Difficulty Swallowing (Dysphagia).
Fever and Chills.
Bad Breath.
Stomachache (common in younger children).

⚠️ WHEN TO SEE A DOCTOR
Seek immediate care if your child has:

Difficulty breathing.
Extreme difficulty swallowing (refusing to eat/drink).
Drooling: This is a sign they cannot swallow their own saliva and may have an abscess or blocked airway.
Sore throat lasting longer than 24-48 hours.

Causes: Viral vs. Bacterial

Knowing the cause determines the treatment.

Viral (Most Common): Caused by cold viruses, flu, or Epstein-Barr (Mono). Antibiotics will not help.
Bacterial (Strep Throat): Caused by Streptococcus pyogenes. Requires antibiotics to prevent complications like Rheumatic Fever.

Diagnosis

Doctors use a throat swab to test for bacteria.

Rapid Strep Test: Results in minutes.
Throat Culture: Results in 24-48 hours (more accurate).

Treatment

1. Home Care (For Viral & Bacterial)

Focus on comfort and hydration.

🧂 SALT WATER GARGLE RECIPE
(For children old enough to gargle, usually 8+)

Mix 1 teaspoon of salt into 8 oz of warm water. Gargle and spit. Repeat every few hours to soothe pain and reduce swelling.

2. Medications

Pain Relievers: Acetaminophen (Tylenol) or Ibuprofen (Advil). Never give Aspirin to children due to Reye's Syndrome risk.
Antibiotics: Only prescribed for bacterial infections. You must finish the full course even if the child feels better.

3. Surgery (Tonsillectomy)

Removing tonsils is less common today than in the past. It is usually recommended only if:

Frequent Infections: More than 7 in one year, or 5 per year for two years.
Sleep Apnea: Swollen tonsils block breathing at night.
Tonsillar Abscess: A collection of pus that doesn't respond to meds.

Tetanus

Tetanus is caused by the bacteria Clostridium tetani, which is found in soil and animal manure.

What is Tetanus?
Tetanus is a serious bacterial disease that affects the nervous system, leading to painful muscle contractions. It is commonly known as "Lockjaw" because it often causes the jaw muscles to lock shut.

Key Fact: Unlike most vaccine-preventable diseases, Tetanus is not contagious from person to person. You get it from the environment.

🛑 MYTH BUSTER: The "Rusty Nail."
Myth: "You only get tetanus from rusty nails."

Fact: Rust itself does not cause tetanus. The bacteria live in soil, dust, and manure. A rusty nail is dangerous only because it has likely been outside in the dirt for a long time. You can get tetanus from a clean nail, a gardening tool, or even a rose thorn if it has soil on it.

Symptoms

Symptoms appear anywhere from a few days to weeks after the injury (average 7-8 days). They usually start at the head and move down.

Lockjaw (Trismus): Spasms and stiffness in jaw muscles.
Sardonic Smile: Facial spasms that cause a strange, fixed grin.
Neck Stiffness & Difficulty Swallowing.
Opisthotonos: Severe, painful body spasms that can arch the back uncontrollably. These can be strong enough to break bones.

⚠️ WHEN TO SEE A DOCTOR
See a doctor immediately if you have a deep or dirty wound and:

You haven't had a tetanus shot in the last 5 years.
You are unsure of your vaccination status.

For minor, clean wounds, the rule is usually every 10 years.

How do you get it?

The bacteria enter the body through broken skin. Common entry points include:

Puncture wounds (nails, splinters, piercings).
Gunshot wounds or crush injuries.
Burns or surgical wounds.
Infected foot ulcers (common in diabetics).

Treatment

There is no cure for tetanus once the toxin binds to nerve endings. Treatment focuses on managing symptoms while the body heals (which takes months).

Tetanus Antitoxin (TIG): Can neutralize toxin that hasn't yet bonded to nerves.
Sedatives: To control severe muscle spasms.
Ventilator Support: Often required because muscle spasms can stop breathing.

Prevention: The Vaccine

Tetanus is 100% preventable with vaccination.

DTaP: Given to young children in a series of 5 shots.
Tdap: The booster shot given to pre-teens and adults (also protects against Pertussis/Whooping Cough).
The "10-Year Rule": Adults should get a Td booster every 10 years.

Immediate Wound Care

If you step on a nail or get a dirty cut, do this immediately:

Control Bleeding: Apply direct pressure.
Cleanse: Rinse thoroughly with clean running water to flush out bacteria. Wash the area with soap.
Antibiotic Cream: Apply a thin layer of Neosporin or Polysporin to discourage bacterial growth.
Cover: Bandage the wound to keep dirt out.
Seek Medical Help: If the wound is deep or contains debris that you can't remove.

What is Cholera?
Cholera is an acute bacterial infection of the intestine caused by Vibrio cholerae. It spreads through contaminated water or food.

The Danger: It causes painless but massive watery diarrhea. Without treatment, severe dehydration can lead to death in hours, even in previously healthy people.

Symptoms: The "Rice-Water" Stool

Most infections are mild, but 1 in 10 people develop severe symptoms. The hallmark sign appears quickly:

Profuse Diarrhea: The stool looks like pale, milky water (rice-water stool) and has a fishy odor. You can lose up to 1 liter of fluid per hour.
Vomiting: Often occurs in the early stages.
Muscle Cramps: Caused by the rapid loss of salts (sodium, potassium).

⚠️ EMERGENCY: SEVERE DEHYDRATION
Seek immediate medical help if you see these signs of shock:

Sunken eyes and dry mouth.
Skin Turgor: If you pinch the skin, it stays "tented" and doesn't bounce back.
Cold, clammy skin.
Little or no urine output.

Transmission

Cholera bacteria live in water and are passed through feces. You catch it by:

Drinking Contaminated Water: The most common cause in areas with poor sanitation.
Eating Raw Shellfish: Oysters and crabs from infected waters.
Raw Fruits/Vegetables: Unpeeled produce washed in untreated water.

Note: Cholera is NOT typically spread by casual person-to-person contact (like shaking hands).

Who is at Risk?

Blood Type O: For reasons not fully understood, people with Type O blood are twice as likely to develop severe cholera if infected.
Low Stomach Acid: Stomach acid kills bacteria. People taking antacids (H2 blockers, PPIs) are more vulnerable.
Travelers: Visiting areas with poor sanitation (parts of Africa, Southeast Asia, Haiti).

Treatment: The Cure is Hydration

Cholera is easily treatable. The goal is simply to replace the fluids lost.

1. Oral Rehydration Salts (ORS)

This is the gold standard. Packets of salt/sugar powder are mixed with clean water to rapidly absorb into the body.

💧 LIFE-SAVING HOME RECIPE
If you cannot reach a hospital and have no medical ORS packets, make this immediately:

Mix together:

1 Quart (1 Liter) of bottled or boiled water.
6 Teaspoons of Sugar.
1/2 Teaspoon of Salt.

Sip constantly. The sugar helps the gut absorb the salt and water.

2. Antibiotics & Zinc

Antibiotics (like Doxycycline) can shorten the illness but are secondary to hydration. Zinc supplements help reduce diarrhea duration in children.

Prevention Rules

If traveling to an endemic area:

The Golden Rule: "Boil it, cook it, peel it, or forget it."
Water: Drink only bottled or boiled water. Use it to brush your teeth too.
Ice: Avoid ice in drinks; it is often made from tap water.
Vaccine: Oral cholera vaccines (like Vaxchora) are available for travelers visiting high-risk areas.

What is Alopecia?
Alopecia is the medical term for hair loss. It can affect just your scalp or your entire body.

Normal vs. Excessive: It is normal to shed 50 to 100 hairs a day. If you see bald patches or large clumps coming out in the shower, that is excessive.

Common Types & Symptoms

Hair loss isn't "one size fits all." Identifying the pattern helps find the cause.

1. Androgenetic Alopecia (Pattern Baldness)

The most common hereditary type.

Men: Receding hairline (M-shape) and thinning at the crown.
Women: General thinning on top of the head; the part line widens.

2. Alopecia Areata (Patchy Loss)

An autoimmune disease where the body attacks hair follicles.

Symptoms: Smooth, round, coin-sized bald spots on the scalp, beard, or eyebrows.

3. Telogen Effluvium (Stress Shedding)

Temporary hair loss triggered by a shock to the system.

Symptoms: Handfuls of hair come out when combing or washing. This usually happens 3 months after a stressful event (illness, childbirth, surgery).

Causes & Triggers

Genetics: Family history is the #1 predictor.
Hormones: Pregnancy, menopause, or thyroid problems.
Medications: Drugs for cancer, arthritis, depression, and heart problems.
Hairstyles: Tight braids or cornrows cause Traction Alopecia.
Poor Nutrition: Lack of Iron or Protein.

Diagnosis

Doctors use simple tests to find the root cause:

The Pull Test: Gently pulling a dozen hairs to see how many come out.
Blood Tests: To check Iron levels (Ferritin) and Thyroid function (TSH).
Scalp Biopsy: Scraping a small sample to check for infection or follicle health.

Treatment Options

Treatments work best when started early. Once the follicle scars over, hair cannot grow back.

1. Medications (FDA Approved)

Minoxidil (Rogaine): Over-the-counter foam/liquid. Helps slow loss and regrow hair. Must be used indefinitely.
Finasteride (Propecia): Prescription pill for men. It blocks the hormone (DHT) that shrinks hair follicles.

2. Medical Procedures

Hair Transplant: Moving hair plugs from the back of the scalp to bald areas.
PRP (Platelet-Rich Plasma): Injecting your own blood plasma into the scalp to stimulate follicles.

Lifestyle & Prevention

🥗 DIET MATTERS
Your hair needs fuel to grow. Ensure you are getting enough:

Protein: Hair is made of keratin (a protein).
Iron: Iron deficiency anemia is a major cause of hair loss in women.

Be Gentle: Use a wide-tooth comb on wet hair.
Avoid Heat: Limit hot rollers and curling irons.
Loose Styles: Avoid tight ponytails that pull on the hairline.

The aortic valve is the final door the blood passes through before leaving the heart to feed the body.

What is Aortic Valve Disease?
The aortic valve sits between the heart's main pumping chamber (left ventricle) and the main artery (aorta). If this valve doesn't open or close correctly, the heart must work harder to push blood out.

The Consequence: Over time, this extra work weakens the heart muscle, leading to heart failure.

The Two Main Problems

Valve disease generally falls into two categories. Some patients have both.

Type	The Mechanical Issue	The Result
Aortic Stenosis	The valve becomes stiff, calcified, and narrow. It cannot open fully.	The heart must squeeze forcefully to push blood through a tiny opening.
Aortic Regurgitation	The valve leaflets are loose or floppy. They do not close tightly.	Blood leaks backward into the heart after every beat.

[Image of aortic stenosis vs normal valve]

Symptoms

In the early stages, there may be no symptoms. As the disease progresses, the heart struggles to keep up with demand.

Murmur: An abnormal whooshing sound heard by a doctor during a checkup.
Chest Pain (Angina): Tightness or pressure, especially during exercise.
Shortness of Breath: Feeling winded easily or when lying flat.
Fainting (Syncope): Feeling dizzy or passing out during activity.
Fatigue: Extreme tiredness.

⚠️ THE "WAIT AND SEE" TRAP
If you have severe aortic stenosis and start experiencing symptoms (chest pain, fainting, or breathlessness), the survival rate drops significantly without surgery. Do not ignore symptoms.

Causes & Risk Factors

Calcification (Aging): Calcium deposits build up on the valve over decades, stiffening it. This is the most common cause in seniors.
Bicuspid Aortic Valve: A birth defect where the valve has only two flaps (leaflets) instead of three. This wears out the valve faster.
Rheumatic Fever: An untreated strep throat infection in childhood can scar the heart valves.
Endocarditis: An infection of the heart lining.

Diagnosis

The gold standard for diagnosis is the Echocardiogram (Heart Ultrasound).

It visualizes the valve movement.
It measures the pressure across the valve.
It checks the size of the heart chambers.

Treatment Options

Valve damage cannot be reversed with medication, but surgery can fix the problem effectively.

1. Surgical Aortic Valve Replacement (SAVR)

Traditional open-heart surgery. The surgeon removes the damaged valve and replaces it with a new one.

Mechanical Valve: Made of metal/carbon. Lasts a lifetime but requires blood thinners.
Biological Valve: Made of cow or pig tissue. No blood thinners needed, but wears out in 10-15 years.

2. TAVR (Transcatheter Aortic Valve Replacement)

A newer, minimally invasive procedure. A collapsed replacement valve is threaded through a catheter in the leg artery up to the heart. It expands inside the old valve, pushing it out of the way.

TAVR offers a faster recovery time than open surgery and is now available for many patients, not just high-risk ones.

🦷 SURPRISING TIP: DENTAL HEALTH
Bacteria from gum disease can enter the bloodstream and infect damaged heart valves (Endocarditis).

Action: Brush and floss daily, and tell your dentist about your heart condition before any major dental work.

Adult ADHD

ADHD is a neurodevelopmental disorder. Brain scans often show differences in the prefrontal cortex, the area responsible for focus and impulse control.

What is Adult ADHD?
Adult Attention-Deficit/Hyperactivity Disorder (ADHD) is a mental health condition characterized by difficulty maintaining attention, hyperactivity, and impulsive behavior.

Key Insight: ADHD does not suddenly develop in adulthood. It always starts in childhood, but many people are not diagnosed until later in life when the demands of work or relationships become overwhelming.

Symptoms

ADHD looks different in adults than in children. While kids may run around the classroom, adults often experience "internal restlessness." Symptoms fall into three categories:

1. Inattention (The "Dreamer")

Poor Focus: Difficulty staying on task for tedious activities.
Disorganization: Messy homes, workspaces, or cars.
Forgetfulness: Frequently losing keys, phones, or wallets.
Time Blindness: Chronic lateness or underestimating how long tasks take.

2. Hyperactivity & Impulsivity (The "Motor")

Inner Restlessness: Feeling like you are driven by a motor; inability to relax.
Impulsive Spending: Buying things on a whim without budgeting.
Interrupting: Finishing other people's sentences or blurting out answers.
Fidgeting: Tapping feet, clicking pens, or pacing.

3. Emotional Regulation

Hot Temper: Quick flashes of anger or frustration (low frustration tolerance).
Mood Swings: Rapid changes in mood depending on the situation.
Sensitivity: Extreme sensitivity to criticism or rejection (often called RSD).

The Science: Why is this happening?

Researchers believe ADHD involves a dysregulation of neurotransmitters—specifically Dopamine and Norepinephrine.

In an ADHD brain, dopamine (the "reward" chemical) is reabsorbed too quickly, making it hard to sustain interest in tasks that aren't immediately exciting.

Complications & Comorbidities

Undiagnosed ADHD often leads to secondary problems:

Work/School: History of underachievement or frequent job changes.
Relationships: Partners may feel ignored or burdened by household responsibilities.
Mental Health: Many adults with ADHD also suffer from Anxiety or Depression.

Diagnosis

There is no single blood test for ADHD. Diagnosis involves:

Clinical Interview: A detailed history of your life from childhood to now.
Rating Scales: Questionnaires (like the ASRS) filled out by you and a partner/parent.
Ruling Out: Ensuring symptoms aren't caused by thyroid issues, sleep apnea, or trauma.

Treatment

The most effective treatment is usually a combination of medication and therapy.

1. Medications

Stimulants: (e.g., Adderall, Ritalin, Vyvanse). These boost dopamine levels to improve focus. They are fast-acting.
Non-Stimulants: (e.g., Strattera, Wellbutrin). These take weeks to build up but are good options for those who cannot tolerate stimulants.

2. Therapy

CBT (Cognitive Behavioral Therapy): Helps change negative thinking patterns ("I'm lazy") into constructive ones.
ADHD Coaching: Focuses on practical skills like organization and time management.

The ADHD Productivity Toolkit

🛠️ COPING STRATEGIES
Pills don't teach skills. Try these hacks:

Body Doubling: Work alongside someone else (even silently) to stay on task.
The "Ohio" Rule: Only Handle It Once. If a task (like opening mail) takes less than 2 minutes, do it immediately.
Visual Cues: Use sticky notes or whiteboards. If you can't see it, it doesn't exist.
Break it Down: Don't write "Clean House" on your to-do list. Write "Pick up socks," "Wash dishes," etc.

Spinal cord injury

The higher the injury to the spinal cord, the more function is lost.

What is a Spinal Cord Injury?
It is damage to any part of the spinal cord or nerves at the end of the spinal canal.

The "Message Highway": Think of the spinal cord as the highway sending messages between your brain and body. An injury creates a roadblock.

Complete Injury: All feeling and motor control are lost below the injury.
Incomplete Injury: Some motor or sensory function remains below the injury.

🚑 EMERGENCY: ACCIDENT PROTOCOL
If you suspect someone has a back or neck injury:

DO NOT MOVE THEM. Moving them can cause permanent paralysis.
Call 911 immediately.
Keep the person still. Place heavy towels on both sides of the neck to prevent movement until help arrives.

Symptoms by Level

The severity of symptoms depends on the "neurological level" of the injury.

1. Tetraplegia (Quadriplegia)

Injury Level: Cervical Spine (Neck).
Effect: Arms, hands, trunk, legs, and pelvic organs are all affected. May require breathing assistance.

2. Paraplegia

Injury Level: Thoracic, Lumbar, or Sacral (Back).
Effect: Paralysis affects all or part of the trunk, legs, and pelvic organs. Arms and hands usually function normally.

Anatomy

[Image of spinal cord anatomy and dermatomes]

The spinal cord is protected by bones called vertebrae. Nerves exit the cord to control specific body parts:

Cervical (Neck): Diaphragm, arms, and hands.
Thoracic (Upper Back): Chest and abdominal muscles.
Lumbar (Lower Back): Legs and hips.
Sacral (Tailbone): Bowel, bladder, and sexual function.

Critical Complications

SCI affects more than just walking; it changes how the body functions internally.

⚠️ AUTONOMIC DYSREFLEXIA
For injuries above T6, a minor irritation (like a full bladder or tight clothes) can trigger a life-threatening spike in blood pressure.
Symptoms: Pounding headache, flushed face, sweating above injury level, slow heart rate.
Action: Sit up immediately, loosen clothes, check bladder/catheter, and seek help.

Other Complications

Pressure Sores: Because you cannot feel pain, sitting in one spot too long cuts off blood flow, causing skin to die.
Neurogenic Bladder: The brain cannot control the bladder sphincter, increasing the risk of UTIs and kidney stones.
Spasticity: Uncontrolled tightening or twitching of muscles.

Diagnosis & Treatment

Diagnosis: CT scans and MRIs determine if the cord is compressed by bone fragments or blood clots.

Acute Treatment

Immobilization: Traction or braces to align the spine.
Surgery: To remove bone fragments or stabilize fractured vertebrae.
Methylprednisolone: A steroid sometimes used within 8 hours of injury to reduce inflammation (though this is debated).

Rehabilitation

Recovery focuses on maximizing independence:

Physical Therapy: Strengthening existing muscles.
Occupational Therapy: Learning to dress, eat, and use adaptive devices.
Robotic Gait Training: Emerging tech to retrain walking patterns.

Lifestyle: Living with SCI

Skin Checks: You must check your skin (using a mirror) twice a day for red spots to prevent pressure sores.
Weight Shifts: If in a wheelchair, perform "pressure relief" weight shifts every 15-30 minutes.
Catheter Care: Strict hygiene is required to prevent urinary tract infections (UTIs).
Mental Health: Depression is common after injury. Connecting with support groups is a vital part of recovery.
