In this lecture from This is Why, Dr. Busti will make the identification of the heart borders and heart chambers on a chest x-ray easy. Dr. Busti will walk step-by-step through how to identify the cardiac silhouette, locate the heart borders, and understand where the right atrium, left atrium, right ventricle, left ventricle, left atrial appendage, and apex of the heart sit on a standard PA chest x-ray (CXR).

You’ll see how to connect real heart xray images with the underlying heart anatomy.

You’ll learn how to:
- Identify normal heart borders on a chest xray
- Recognize which heart chambers form the right and left heart borders
- Understand where the right ventricle and left atrium actually sit on a CXR
- Use the silhouette sign to localize lung pathology next to the heart
- Apply a simple, repeatable approach to chest xray interpretation

The goal = make medical education easy and clinically relevant.

In this lecture from This is Why, Dr. Busti will break down dysphagia—the medical term for difficulty swallowing—in a clear, clinically relevant way. You’ll learn what dysphagia means, how clinicians use the term, and how to quickly recognize the difference between oropharyngeal dysphagia vs esophageal dysphagia. We’ll also cover high-yield dysphagia causes, red flags, and common pitfalls that lead to missed diagnoses—especially when aspiration risk is overlooked.

What you’ll learn (quick + practical):

- Dysphagia definition and how it shows up in real patients (“trouble swallowing)

- Oropharyngeal vs esophageal dysphagia: symptom patterns that matter

- Common causes: stroke dysphagia, Parkinson disease, dementia, neurologic/neuromuscular conditions, GERD, strictures/rings, eosinophilic esophagitis, and achalasia

- Complications: aspiration, aspiration pneumonia, dehydration, malnutrition, food impaction

- Evaluation basics: bedside swallow assessment, swallow evaluation, modified barium swallow / VFSS, FEES, barium swallow, and upper endoscopy (EGD)

The goal = make medical education easy and clinically relevant.

What does “micturate” actually mean, and why do textbooks, exam questions, and older charts still use it instead of just saying “urinate”? In this lecture on Medical Terminology from This is Why, Dr. Busti breaks down the meaning and definition of micturate, how it relates to micturition and urination, and shows you exactly how this term is used in real clinical practice so it finally sticks.

In this video, you’ll learn: what micturate and micturition mean in plain language, how to connect “micturate = urinate” so you never freeze on an exam, how the term shows up in phrases like “burning on micturition” (classic for urinary tract infections) and “micturition reflex”, and how to recognize when to use more common language like “void” or “urinate” with patients and in charting.

Mastering chest X-ray positioning is the first step to safe and accurate chest X-ray interpretation. In this video, “How to Check Patient Positioning on a Chest X-Ray,” Dr. Busti walk through a simple, practical checklist so you can quickly decide if a CXR is good enough to interpret—or if positioning errors (rotation, poor inspiration, clipping) are misleading you.

You’ll learn how to:
Tell PA vs AP views and why it matters for heart size and mediastinum
Spot patient rotation using the clavicles and spinous processes
Assess inspiration on a chest X-ray (how many ribs is “good enough”?)
Check centering and coverage so the lung apices and costophrenic angles aren’t cut off
Avoid common mistakes that lead to false positives and missed pathology
