Heart Failure Classifications: A Quick Review

[🦠 Dr. Ahmed Alanazi @o_o_dr]

Hyperkalemia is one of the few laboratory abnormalities that can kill a patient within minutes ⚡🫀

📌 Peaked T waves
📌 PR prolongation
📌 Wide QRS complex
📌 Sine-wave pattern
📌 Ventricular fibrillation or asystole

Remember the treatment sequence:

❤️ Stabilize the heart → IV Calcium

➡️ Shift potassium into cells → Insulin + Dextrose, β₂-agonist

🗑️ Remove potassium from the body → Diuretics, Potassium binders, Dialysis

Treat the ECG, not just the potassium level.

👁️ 7 Causes of Red Eye

A red eye is common—but not always benign. While many cases are due to simple conjunctivitis, some causes can threaten vision and require urgent ophthalmology review.

⸻

1️⃣ Conjunctivitis
➊ Most common cause of red eye
➋ Presents with redness, discharge, irritation, and tearing
➌ Usually viral, bacterial, or allergic

2️⃣ Uveitis
➊ Painful red eye with photophobia
➋ May be associated with autoimmune disease
➌ Requires urgent specialist assessment

3️⃣ Keratitis
➊ Corneal inflammation/infection
➋ Severe pain, photophobia, reduced vision
➌ Contact lens wearers are at increased risk

4️⃣ Acute Angle-Closure Glaucoma
➊ Sudden severe eye pain and headache
➋ Blurred vision, halos around lights, nausea/vomiting
➌ Ophthalmic emergency 🚨

5️⃣ Scleritis
➊ Deep, severe eye pain
➋ Often associated with systemic autoimmune disease
➌ Requires urgent treatment

6️⃣ Episcleritis
➊ Mild discomfort with sectoral redness
➋ Usually self-limiting and benign
➌ Vision is typically preserved

7️⃣ Corneal Abrasion
➊ History of trauma or foreign body
➋ Pain, tearing, and foreign body sensation
➌ Fluorescein staining confirms diagnosis

⸻

🚨 Red Flags in a Red Eye
🔴 Severe eye pain
🔴 Sudden reduction in vision
🔴 Photophobia
🔴 Halos around lights
🔴 Nausea/vomiting with eye pain
🔴 Contact lens wearer with painful red eye

💡 Clinical Pearl:
Painful red eye + reduced vision = urgent ophthalmology review until proven otherwise.

🧠 BRAINSTEM & CRANIAL NERVES MADE EASY

Mastering the brainstem is one of the fastest ways to localize neurological lesions and ace exams! Remember the simple sequence:

MIDBRAIN → PONS → MEDULLA

⸻

1️⃣ Midbrain (CN III & IV)

➊ CN III – Oculomotor
• Controls most eye movements, eyelid elevation, and pupillary constriction
• Lesion → Ptosis, dilated pupil, “down and out” eye

➋ CN IV – Trochlear
• Innervates the superior oblique muscle
• Lesion → Vertical diplopia, difficulty looking down, trouble walking downstairs

💡 Pearl: “Down and Out + Ptosis = CN III palsy”

⸻

2️⃣ Pons (CN V, VI, VII, VIII)

➊ CN V – Trigeminal
• Facial sensation (V1–V3) + muscles of mastication
• Loss → Facial numbness, weak jaw, absent corneal reflex

➋ CN VI – Abducens
• Abducts the eye (lateral rectus)
• Lesion → Failure to abduct + horizontal diplopia

➌ CN VII – Facial
• Facial expression, taste anterior 2/3 of tongue
• Lesion → Facial weakness

➍ CN VIII – Vestibulocochlear
• Hearing and balance
• Lesion → Vertigo, hearing loss, nystagmus

💡 Pearl: Diplopia worse when looking toward the affected side suggests CN VI palsy.

⸻

3️⃣ Medulla (CN IX, X, XI, XII)

➊ CN IX – Glossopharyngeal
• Sensory limb of gag reflex
• Taste posterior 1/3 of tongue

➋ CN X – Vagus
• Motor limb of gag reflex, palate elevation, phonation
• Lesion → Hoarseness, dysphagia, uvula deviates away from the lesion

➌ CN XI – Accessory
• Sternocleidomastoid and trapezius muscles
• Lesion → Shoulder droop and weak head rotation

➍ CN XII – Hypoglossal
• Tongue movement
• LMN lesion → Tongue deviates towards the lesion

💡 Pearl: CN IX + X + XI involvement = think jugular foramen lesion.

⸻

🚨 High-Yield Localization

🟣 Midbrain: CN III, IV
🟢 Pons: CN V, VI, VII, VIII
🔴 Medulla: CN IX, X, XI, XII

Remember:

3-4 Midbrain → 5-8 Pons → 9-12 Medulla

CHA2DS2 VASc score.

[🦠 Dr. Ahmed Alanazi @o_o_dr]

Dialysis is not one treatment—it comes in different forms, each designed for a different patient 🩺🩸

📌 Hemodialysis (HD)
📌 Peritoneal Dialysis (PD)
📌 Continuous Renal Replacement Therapy (CRRT)

Knowing the differences is high-yield for both exams and clinical practice.

🏥 HD → Fast and efficient solute removal
🏠 PD → Home-based and gentle fluid shifts
🚨 CRRT → Preferred for unstable ICU patients

Remember the classic AEIOU indications:

🩸 Acidosis
⚡ Electrolyte abnormalities
☠️ Intoxications
💧 Overload
🧠 Uremia

Choose the right modality for the right patient at the right time.
