Cerebral vasculitis is a known cause of ischemic and hemorrhagic strokes and has been described as one of the rare but important causes of corpus callosum infarction. Biopsy-proved giant cell arteritis causing callosal infarction is an exceedingly rare finding because a tissue specimen is usually not obtained and conclusions are drawn on the basis of clinical and radiologic findings alone. We present a case of callosal infarction, which evolved and eventually affected large portions of both cerebral hemispheres.
A 63-year-old woman presented to our hospital with left-sided numbness and neglect, cognitive changes, and apraxia. One month earlier, she was found to have a C-reactive protein level of 8.0 mg/dL (normal <0.5 mg/dL) and 75% stenosis in both femoral arteries. These results prompted Read more »

Diverticula are small outpouchings that develop at weak points along the wall of the colon (large bowel), probably because of high pressures associated with muscle contractions during the passage of stool. When these sacs become obstructed and/or inflamed (most frequently in middle-aged or elderly individuals), they enlarge and create pain and fever. Usually, the left lower quadrant is involved, because diverticula tend to form in the left-side portion of the colon (descending colon) more frequently than in the right-side portion (ascending colon) or horizontal connecting section (transverse colon). A ruptured diverticulum can cause a clinical picture much like that of a ruptured appendix, with pain in the left side of the abdomen instead of the right side. The victim should seek medical attention, and his diet be limited to clear fluids. Antibiotics (metronidazole, metronidazole combined with doxycycline, amoxicillin-clavulanate, trimethoprim-sulfamethoxazole, cefixime, ciprofloxacin, or cefpodoxime) should be administered if help is more than 24 hours away.
As the population ages, diverticulitis is expected to become more prevalent. In a recent article Read more »

Researchers at Johns Hopkins published a study that reports that MRI scans CAN cause feelings of dizziness induced by magnetic fields causing motion of the electrically charged fluid of the inner ear.
In both ears, there is a “gyroscope” called the labyrinth. Whenever the head turns or a force like gravity is exerted on this system, fluid moves within, which tells the brain that motion has occurred. It’s much like looking into a glass of water and based on the way the water tilts in the glass, you can guess which way motion is occurring.
In any case, the study Read more »

It is a prevalent belief out in the medical (and lay public) community that patients with iodine or seafood allergy can not receive contrast when undergoing certain radiological tests like CT or MRI scans. The concern is that contrast contains minute amounts of free iodide and as such, IV administration of this material puts the patient at risk of a life-threatening anaphylactic reaction.
Contrast is often given in these tests as it traces out bloodflow enabling the physician to see organ and mass architecture much more clearly allowing for improved accuracy in seeing anything abnormal.
Well… rest assured that patients with iodine and seafood allergy CAN receive contrast without any significant increased risk of an allergic reaction as compared to other allergies.
In a large study encompassing 112,003 patients, Read more »

In preparation of Internal Medicine 2011 in San Diego this week, the unavoidable choice to make isn’t which sessions to attend, but even before arriving: Will you pass through the airport’s security scanners, or opt for the pat down?
Physicians themselves are split on the issue, with some physicians opting out of repeat scanning in favor of the pat down search.
“I do whatever I can to avoid the scanner,” one physician told CNN. Other physicians interviewed were split on the issue one way or another. But as a frequent flier, this doctor was concerned about the cumulative effect. “This is a total body scan–not a dental or chest X-ray. Total body radiation is not something I find very comforting based on my medical knowledge.” Read more »
