Persistent Left Superior Vena Cava

In this case, when Dr. subclavian vein cannulation, is that the wire enters the coronary sinus, decides to do an angiogram.

Case performance in Puerto Rico.

wikipidea info:
In anatomy, a persistent left superior vena cava (PLSVC) is the most common variation of the thoracic venous system,[1][2] is prevalent in 0.3% of the population,[3] and an embryologic remnant that results from a failure to involute.

In PLSVC, the left brachiocephalic vein does not develop fully and the left upper limb and head & neck drain into the right atrium via the coronary sinus.

The variation, in isolation, is considered benign, but is very frequently associated with cardiac abnormalities (e.g. ventricular septal defect, atrioventricular septal defect) that have a significant mortality and morbidity.[4] It is more frequent in patients with congenital heart defects.[5]

kristinmountillustration: This is an illustration I did of an inferior view the optic nerve and its relationship to the eyes and brain. This client wanted a vector piece, and it was around 1995, so the was done entirely in Adobe Illustrator 5.0. Yes, that’s version 5.0, not CS5!  The subtle shading and highlights among the sulci (the deep creases on the brain’s surface) were done with gradients. Back in Illustrator 5.0, gradients weren’t as easily editable as they are now. The entire gradient had to be recreated if you wanted to change anything about it. So although I liked the outcome of this brain piece, it was a slightly tedious process. The optic nerve is also known as cranial nerve II. There are twelve cranial nerves, and each has its own name. In order to remember these names in my gross anatomy class, we were given a mnemonic: “On old olympic towering tops, a Finn and German viewed some hops.” The first letters of the words in this sentence helped us remember the twelve cranial nerves in order: I: Olfactory II: Optic III: Oculomotor IV: Trochlear V: Trigeminal VI: Abducens VII: Facial VIII: Acoustic IX: Glossopharyngeal X: Vagus XI: Spinal Accessory XII: Hypoglossal There are many other medical school mnemonics, many which are somewhat X-rated. I remember one in particular about a zebra. Anyone else know this one?

Penicillin allergy.

Definition

Penicillin allergy is an overreaction by your immune system to penicillin and related antibiotics. If you have a penicillin allergy, your reaction to taking the antibiotic may range from a rash to anaphylaxis, a potentially life-threatening condition.

Penicillin antibiotics are widely prescribed for bacterial infections, such as strep throat. However, not all unfavorable reactions to penicillin are a true penicillin allergy.

It isn’t clear why some people develop penicillin allergy. Once you’ve had an allergic reaction to penicillin, the simplest way to prevent penicillin allergy is to avoid penicillin and related antibiotics.

LEFT: This is an image of the brain with bacterial meningitis, note that the usually delicate and transparent arachnoid space is filled with a yellowish exudates. RIGHT: Microscopic examination of this space shows that it is filled with white blood cells and tissue debris. The arrow head marks the pial surface and the arrow labels the subjacent cerebral cortex.

Encephalitis and Meningitis.

What is encephalitis?

Encephalitis is an inflammation of the brain. There are many types of encephalitis, most of which are caused by infections. Most often these infections are caused by viruses. In addition to infections, encephalitis can also be caused by certain diseases that result in an inflammation of the brain.
