What are the risk factors for atheroslerosis?

This was my learning issue regarding atherosclerosis. The discussion is only limited to the traditional risk factors as well as the novel ones.

Facebook integration?

The site admin strives to make this blog the best it could be by delivering weblogs regarding the activities done by the Tinglan group as well as making it integrated and user-friendly as much as possible.

To this end, attempts shall be made to make the site integrated to social networking sites.

Best of luck to me!

Trivia on Percussion

The following are probably only found in the history books but this is still interesting for me. I wish to share it with you guys.

In 1761, Leopold Auenbrugger, a Viennese physician, published a book proposing "percussion of the human thorax, whereby, according to the character of the particular sounds thence elicited, an opinion is formed of the internal state of that cavity."² He had observed his father, an innkeeper, use this technique to check the wine levels in his casks. Although his discovery was initially ignored, percussion was reintroduced by Jean-Nicolas Corvisart in early 19th-century France, and became an essential addition to the chest examination until it was mostly supplanted by the chest x-ray.

Temperature-Pulse Relationship

I've always wanted to know, the values used to determine relative bradycardia in a patient. Thankfully, I was able to encounter one article that points to a approximation. I encountered the table while I was reading on atypical pneumonias (so don't be surprised if you might be reading about it).

Temperature-Pulse Relationships (temperature and corresponding pulse [beats/min])

Appropriate Pulse Relative Bradycardia

41.1°C/106°F = 150/min <140/min

40.6°C/105°F = 140/min <130/min

40.0°C/104°F = 130/min <120/min

39.5°C/103°F = 120/min <110/min

38.9°C/102°F = 110/min <100/min

Good luck in the pulmonology exams Batch 2009-2013!

Videos:The Pulmonary Systerm and Bohr Effect

Here are two videos, I stumbled upon while doing my self-directed learning. I wish to share this with you guys.

This video shows pulmonary system including the lungs, larynx, trachea, bronchi, bronchioles, alveoli and thoracic diaphragm.




This video has a great discussion on the Bohr Effect.

What is the P2?

To understand the P2 sound, we must first be acquainted with the second heart sound.

What is the second heart sound?

The second heart sound (S2) is a short burst of auditory vibrations of varying intensity, frequency, quality, and duration. It has two audible components, the aortic closure sound (A2) and the pulmonic closure sound (P2), which are normally split on inspiration and virtually single on expiration. S2 is produced in part by hemodynamic events immediately following closure of the aortic and pulmonic valves.
