We talked about salad and kidney dialysis.
A salad is a healthy food made mostly of raw or cooked vegetables, sometimes with fruits, nuts, or meat, and usually eaten cold.

Kidney dialysis is a treatment used when the kidneys stop working. It cleans the blood from waste and extra water. Most dialysis patients do not stay in the hospital all the time. They usually go to the hospital 3 times a week, stay 3–4 hours each time, and then go home.

There are two main types of dialysis. Hemodialysis is done with a machine, usually 3 times per week. Peritoneal dialysis can be done daily. Sometimes dialysis is done through the neck using a temporary tube, especially in emergencies or when the arm is not ready. This neck dialysis is usually temporary because it has a higher risk of infection

📸 What’s the Difference Between X-ray, CT Scan, MRI, and PET?

Doctors order different types of scans depending on what they’re looking for—because each imaging method has its own purpose:

⸻ Zaki Wasel

🩻 1. X-ray:
• The simplest and fastest imaging method
• Used for broken bones, chest infections (like pneumonia), and dental issues
• Provides 2D images
• Cheap, quick, and low radiation
• But it doesn’t show small details like nerves or soft tissue well

💻 2. CT Scan (Computed Tomography):
• An advanced X-ray that provides 3D cross-sectional images
• Used for internal bleeding, tumors, abdominal or brain issues, and complex fractures
• Faster and more detailed than a regular X-ray
• Has higher radiation, so used only when necessary

🧲 3. MRI (Magnetic Resonance Imaging):
• Uses magnets and radio waves, no radiation
• Best for brain, nerves, muscles, cartilage, and joints
• Very detailed but expensive and time-consuming
• Not suitable for people with metal implants or pacemakers

⸻

🔬 PET Scan:
• Measures metabolic activity in the body using a small dose of radioactive tracer
• Used for detecting and tracking cancer and evaluating how well treatment is working

👣 What Is the Babinski Sign?The Babinski sign is a neurological reflex test used to check the health of the corticospinal tract (a pathway that carries movement-related messages from the brain to the spinal cord).✅ Normal (Negative) Babinski Response: • When the bottom of the foot is stroked, the big toe curls downward (flexes), or there is no movement. • This is a normal response in adults.❌ Abnormal (Positive) Babinski Sign: • The big toe moves upward (extends), and the other toes fan out. • This is called a positive Babinski sign, and it suggests damage to the brain or spinal cord, especially the corticospinal tract.⸻🧠 When Is the Babinski Sign Positive?A positive Babinski sign may be seen in: • Stroke • Multiple sclerosis (MS) • Spinal cord injury • Brain tumors • Traumatic brain injury⸻👶 Note About Babies:In infants under 2 years old, a positive Babinski sign is normal because their nervous system is still developing
