This Is Why with Dr. Busti

In this lecture from This is Why, Dr. Busti will walk step-by-step through rib anatomy on a portable AP chest x ray, so you can quickly recognize posterior vs anterior ribs, assess inspiratory effort, and improve your overall chest x ray interpretation skills.

You’ll learn how to:
Spot posterior ribs and anterior ribs on a standard AP chest x ray
Use rib counting to judge film quality and inspiration
Apply rib levels as landmarks when describing lung findings
Avoid common mistakes when reading portable chest x rays in the ER, ICU, and inpatient units

If you’re looking for a clear, visual guide to how to read a chest x ray, chest x ray for beginners, and how to count ribs on a chest x ray, this session is for you.  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.

The goal = make medical education easy and clinically relevant.

In this lecture from This is Why, Dr. Busti will answer the question, "Are patients with a penicillin allergy really at high risk when we use cephalosporins?"

In this episode, we’ll cover:
- Why most penicillin allergy labels are incorrect
- The true risk of cephalosporin cross-reactivity (and why it’s not what you think)
- How R1 side chains drive cross-reactivity between β-lactam antibiotics
- Practical, step-by-step approaches to antibiotic allergy risk stratification

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

The goal = make medical education easy and clinically relevant.

In this lecture from This is Why, Dr. Busti will teach you how to quickly and confidently tell AP vs PA chest X-ray (CXR) views apart so you don’t get misled by magnified hearts or a widened mediastinum. In this video, we break down chest X-ray projection step by step and show you how to spot whether a film is AP or PA view just by looking at the image itself—skills you can use on your next shift or exam.

This teaching video is designed to help clinicians who want practical, bedside chest X-ray interpretation skills. We’ll connect the physics of X ray projection (AP vs PA) with real-world decisions, like when you can and cannot trust the heart size on a portable chest X-ray.

You’ll learn how to:
What AP and PA mean in chest X-ray views and why projection matters
How to recognize AP chest X-ray vs PA chest X-ray using simple visual clues
Why the heart often looks “enlarged” on AP portable CXR
How scapula position, patient posture, and inspiration help you identify the view
Common pitfalls in how to read chest X ray and avoid overcalling cardiomegaly

If you’re looking for chest X-ray basics, how to interpret chest X ray, or a concise refresher on frontal chest X ray positioning, this video will help build your foundation in radiology chest X ray and medical imaging education. The goal = make medical education easy and clinically relevant.

In this This Is Why pharmacology review, Dr. Busti walks through the Selective Serotonin Reuptake Inhibitors (SSRIs)—how they became first-line for major depressive disorder and a wide range of anxiety-related disorders, and where their real-world pitfalls live.

We compare the core agents—citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, and sertraline—covering indications, mechanism, and clinical nuances that matter at the bedside. You’ll learn how dose, half-life, metabolism, and side-effect patterns influence patient-specific choices, and what to monitor for safety and success.

This episode includes practical guidance on:

• Managing sexual dysfunction, QT risk, and SIADH
• Recognizing CYP2D6 interactions
• Understanding fluoxetine’s long half-life
• Applying MAOI washout rules to avoid serotonin syndrome
• Starting low and titrating slow for anxiety

If you want to go beyond memorization and understand the why behind the what, this episode connects the science, safety, and strategy of SSRI use.

This session teaches a reproducible, step-by-step approach to chest X-ray (CXR) interpretation using two complementary mnemonics: RIPE (Rotation, Inspiration, Penetration/Projection, Exposure/Artifacts) to verify image quality, and A-B-C-D-E-F-G-H-I to read findings in a consistent order. Viewers learn to spot essential landmarks (trachea, aortic knob, hila, lobes/fissures, diaphragms, costophrenic angles), recognize when AP vs PA matters (e.g., cardiothoracic ratio), and avoid common pitfalls that lead to misses. A live, real-time read ties the method together so the approach can be used on rounds, in clinic, or at the bedside.

What you’ll learn

• Quality first: use RIPE to confirm a film is worth interpreting
• A structured read with A-B-C-D-E-F-G-H-I
• How projection changes appearance (AP vs PA vs lateral)
• Reliable checks for effusions, pneumothorax, edema, and device/artifact confounders
• How to synthesize a clear impression clinicians can act on
