Med-sources II

Action speaks louder than words!
It takes a great deal to be an expert in anatomy. Tens and hundreds of pictures from all angles given in the book/ atlas can sometimes do nothing. So, here is a one stop website to learn basic anatomy and basic physiology of the respiratory system using animations.

Did you know just like an instagram for doctors, there is an youtube for medicos? And a kinda sorta wikipedia? Well, now you know!

Also, bookmark this. It contains some anatomy, histology and embryology.

This was in my drafts. Saved in November 2011. Posting it now for our new 1st and 2nd year medicos.

Radiology

Resumed studying after a 2 week hiatus, due to earthquake, with radiology. I read somewhere, there are two types of clinicians- radiologists and those who wish they were radiologists. Isn't it right? Who wouldn't want to sit in those comfy chairs and not listen to patient's stories, both at the same time. Seems like a vacation to me.

Found two very useful sites which may help you for Radiology in your final year.
1. Radiology Masterclass - The tutorials and galleries will give a good foundation knowledge in the art of radiological interpretation.

2. Radiopaedia - A large collection of radiology cases and topics in encyclopedia.

Mitral Stenosis X- Ray Findings

Radiological signs seen in mitral stenosis are:

§  Backward displacement of esophagus by enlarged left atrium (in lateral view X-ray). Also the earliest sign.

§  Straightening of left heart border due to enlarged left atrium.

§  Double shadow due to enlarged left atrium. Dense right atrial shadow superimposed within fainter left atrial shadow that touches the diaphragm.

§  Splaying of carina (The left main bronchus is lifted up by the enlarged left atrium)

§  Prominent upper zone pulmonary veins (Inverted moustache sign /  Antler’s horn sign / Cephalisation pulmonary of blood flow)

§  Enlarged pulmonary trunk (This occurs following the development of pulmonary hypertension)

§  Kerley B lines (indicating fluid collection in the interlobular septa. 1-2 cm in length lines in lung peripheries perpendicular to and extend out to pleural surfaces.)


NOTE: Here is a chest radiograph exhibiting classic findings of chronic mitral stenosis.

Pathology Slides

Here is a general and systemic pathology website. The site includes photomicrographs, movies and a growing number of interactive clinical cases. There is also self assessment quiz at the end of each unit.
The major sections in the website are:
Inflammation and Repair
Infectious Diseases
Hemodynamic Disorders
Neoplasia
Cardiovascular Diseases
Pulmonary Diseases
Gastrointestinal Diseases
Liver and Gallbladder
Renal Diseases
Reproductive Diseases
Endocrine Diseases
Breast Diseases
Hematologic Disorders
Lymphatic System
Immune System
Pediatric Diseases
Disorders of the skin
Musculoskeletal Disorders
Central Nervous System Disorders

The basis for physiology- Action Potential. Instead of tiring your eyes trying to understand this topic from the text-book, check this Action Potential animation. It'll save hours of your study time and save you some sleep-time.

For understanding Michaelis-Menten Equation, this you-tube video can have no competition. Fantastic. 

Learning Embryology made li'l easy..

Your exploration of development of embryology can begin in many different ways, if at all you plan in beginning it unlike me. I attended just a few lectures of the few lectures given and we weren't given the class presentations' copy either.

I just read the few questions given in the BSR (and the answers were from the internet) before the finals, and my good luck-the question of the finals was there in the BSR.

Now, if you are wondering why I didn't learn the answers from the book. The problem with me is I require animations, pictures ( a lot of them!!) or videos to understand stuffs  making it easy to learn. And, development is a dynamic process so what else other than pictures, animations, flash movies can make it better to  learn from.

So,while browsing for embryology content in the internet I came across a very few sites which might be helpful for you as well. If you like animations click here and for pictorial understanding along with written content click here. Here's a website providing 3-D MRI of human embryo and collection of images.


Update: Read it in AP's blog- Embryology, so far, makes me wish the human race could have just stayed embryos -structures would have been much easier to memorize. Pharyngeal arches, cuter muscles and bones, and all of the organ relations were so easy before they went and twisted around on each other: Heart= central, liver= central, right side of the heart= the actual right side of the heart...c'mon (Special bonus: tails.)
That's awesome, right?!

NOTE: 

* Consult your book along with the sites for the flow of subject matter.

* Since I didn't read embryology from the start, I don't know how complete these websites provide information. But,however, I liked them.

* BSR- Basic Science Review- a quick revision/review book by our seniors
