Principle #1
State learning objectives Behaviors expected after the presentation
Design your talk according to your objectives
Handouts are recommended
![Page 15: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/15.jpg)
Bad objectives
“Today, I will”:
Review the pathophysiology of X
Show you clinical cases of X
Talk about treatment of X
![Page 16: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/16.jpg)
Good objectives
At the end of the lecture the audience will be able to:
List the different presentations of X
Implement a medical plan for X

![Page 17: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/17.jpg)
Principle #2
Attract and maintain attention
![Page 18: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/18.jpg)
Clear statement of purpose (objectives)
Start by posing a question or dilemma
Attention span= 15-20 minutes Use questioning, brainstorming, and demonstrating
![Page 19: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/19.jpg)
Principle #3
Make only one or two major points
![Page 20: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/20.jpg)
Principle #4
Make the organization clear
![Page 21: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/21.jpg)
Tell them what you are going to tell them
Then, tell them
Finally, tell them what you just told them
![Page 22: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/22.jpg)
Principle #5
Use audio-visual aids that help, not hinder
![Page 23: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/23.jpg)
Do not apologize for slides
People remember 20% of what they hear 30% of what they see 50% of what they see and hear
![Page 24: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/24.jpg)

RESIST THE TEMPTATION TO USE ALL CAPITAL LETTERS. IT MAKES COMPREHENSION HARDER BECAUSE ALL LETTERS ARE THE SAME HEIGHT. WE READ BY RECOGNIZING WORD SHAPES
Resist the temptation to use all capital letters. It makes comprehension harder because all letters are the same height. We read by recognizing word shapes.

Text color
Beware of using too many colors
This can be very distracting
The eyes will be bouncing
![Page 45: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/45.jpg)
Text color
Single colors are more dynamic
Underlie for emphasis
And/or increase font size
![Page 46: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/46.jpg)
Avoid too many bullets and too many words per line
![Page 47: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/47.jpg)
The surgical ellipse
The ellipse is the most common excisional procedure
Usually performed under sterile conditions and local anesthesia using lidocaine1-2% with epinephrine 1:100,000
There is consensus on the guidelines for designing adequate ellipses
Pre-marking skin with gentian violet Delineating margins: 2mm for benign lesions, 5mm or more for malignant lesions
Length: width ratio 3-4:1 30-degree angles on tip
![Page 48: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/48.jpg)
Instead, follow the rule of “6”
Maximum 6 bullets per slide, and
6 words per line
Use diagrams instead of words
![Page 49: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/49.jpg)

Some sobering statistics about our healthcare system
Our current healthcare system incurs over $177 billion annually in mostly avoidable health care costs to treat adverse events from INAPPROPRIATE MEDICATION USE
Treatment of chronic disease costs the health care system over $1.3 trillion annually – diabetes alone is about $170
billion
*About 1/3 of patients who begin a drug regimen never refill the prescription
![Page 56: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/56.jpg)
Things to avoid in your presentation
![Page 57: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/57.jpg)
Too many animations
Too many jokes
Too many pictures
Too much information
![Page 58: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/58.jpg)
The oral presentation
![Page 59: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/59.jpg)
Calculate 1.5 slides for every minute of your talk
Grand rounds= 45 minutes= maximum 67 slides
![Page 60: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/60.jpg)
If you are nervous
Take 1-2 deep breaths
Tense yourself up all over then relax
Know your opening lines to perfection
![Page 61: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/61.jpg)
Start with memorized opening lines and posing a question or
dilemma that lead to your presentation
![Page 62: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/62.jpg)

Do not “read” from your slides
Use them as newspaper headlines
![Page 64: Iv Lectures Carlos](https://reader034.vdocuments.mx/reader034/viewer/2022051817/548234d55906b5e7048b462f/html5/thumbnails/64.jpg)
Dermatologic Surgery encompasses a wide variety of methods to remove or modify skin tissue for health or cosmetic benefit.
These methods provide high-quality, cost-effective skin surgery and include scalpel surgery, laser surgery, chemical surgery, cryosurgery (liquid nitrogen), electrosurgery, aspiration surgery, liposuction, injection of filler substances, and Mohs micrographic controlled surgery (a special technique for the removal of growths, especially skin cancers).
