Every year, a half million bronchoscopies are performed in the U.S. in order to investigate lesions within patients’ lungs. Because conventional bronchoscopy cannot reach the distant regions of the lungs, more invasive surgical procedures are often needed to diagnose lung nodules that may be malignant.
The General Thoracic Surgery Division at NewYork-Presbyterian/Columbia has begun using a new technology, superDimension Electromagnetic Navigation Bronchoscopy™ (ENB). ENB creates a computer-generated reconstruction of the lungs from a CT scan of the tracheobronchial tree, explains Lyall A. Gorenstein, MD, FRCS (C), FACS, Director, Minimally Invasive Thoracic Surgery. Using these reconstructed images, the system creates a visual pathway so that surgeons can guide steerable catheters to where lung nodules are located, facilitating examination and biopsy.

This is not a lesson about the limitations of 140-character messages on Twitter.
Rather, it is a warning about careless Tweets that mischaracterize the real meat of the message in longer stories linked to in the Twitter message. As I wrote on Twitter in response to these two episodes, “Better not to Tweet on complex health care topics than to mischaracterize your own story with a misleading 140 characters.”
First, my friend Andrew Holtz caught the fact earlier this week that Men’s Health Magazine tweeted:
If you’re a smoker, you NEED to get a CT scan. Here’s why: http://ow.ly/5x34y
That “here’s why” link took you to a Men’s Health Magazine story, that despite being headlined “The Medical Test Every Smoker Needs,” went on to explain:
Don’t run out and ask for a CT scan, though. More than 96 percent of the positive screens in the study were false positives, which could subject you to unnecessary surgery, cancer treatments, and the complications that come with them. They’re also expensive: A chest CT scan can cost up to several thousands of dollars.
So look at how silly Men’s Health looked on this confusing back-and-forth message:
1. You NEED to get a CT scan.
2. It’s a test “every smoker needs”
3. But don’t run out and ask for one.
Then this morning I caught AARP doing the same thing. They tweeted:
Are you a smoker? CT scan those lungs – they’re proven to cut risk of lung cancer death for 55-plus: http://aarp.us/rdleHu
That links takes you to a story that includes caveats such as the following: Read more »

If you are a smoker, or love someone who smokes, the specter of lung cancer is ever looming. Wouldn’t it be great if there was a way to detect lung cancer in its earliest and most curable stages, much like the goal of mammograms for breast cancer?
Although it seems like common sense to do such advance checks—a process called lung cancer screening—studies to date haven’t shown that finding lung cancer early translates into fewer deaths from the disease.
A new report in the New England Journal of Medicine suggests that screening heavy smokers with yearly low-dose CT scans can reduce deaths from lung cancer by 20% compared to screening with chest x-rays. The results are from the National Lung Screening Trial, which included more than 53,000 current and former heavy smokers between the ages of 55 and 74. (Preliminary results from this trial were covered in the Harvard Health Letter and in the Harvard Health blog.) Read more »

It is hardly news to say that we need better means to predict who will die of heart disease. No matter how much you may hear about medical errors, hospital acquired infections, or even distracted driving, it’s still heart disease that kills the most of us.
The inflammation that begins narrowing our arteries starts when we are young. It percolates quietly, stealth-like for years. The young usually skate by unscathed. But all the cookies, beers, chips, inactivity and work stress adds up. The tension of life squeezes our arteries, daring them to crack or fissure. This cataclysm is one of the ways that middle age may introduce herself.
A friend, or colleague, or sibling dies suddenly of heart problems. Those of us that our “masters-aged” have likely felt these sensations of sadness, and then the reality that they may be next.
“I should probably come in and get a check-up,” is something I hear frequently in the doctor’s lounge after such a tragedy.
I agree. When you are old enough to use reading glasses it is time to think about what lurks inside your heart’s blood vessels.
But herein lies the catch. Read more »

Improved visualization of the posterior fossa structures has led to an increased recognition of cerebellar malformations, including the Dandy-Walker malformation, Joubert syndrome, rhombencephalosynapsis, tectocerebellar dysrhaphia, and so forth. New anomalies continue to be discovered, highlighting the fact that cerebellar anomalies are poorly understood and have largely been ignored in the literature. We present a structural anomaly of the cerebellum, which we believe has not been previously reported.
A 16-month-old girl presented to the pediatric outpatient department with some delayed developmental milestones. She was full-term with a normal vaginal delivery and no history suggestive of perinatal asphyxia. The motor milestones were delayed, and the child could not stand. The other milestones, including language and socialization, were normal. Examination revealed a bony hard swelling in the occipital region, which, according to the mother, was noticed soon after birth. The occipitofrontal circumference was 52 cm, and the anterior fontanelle was open. There was generalized hypotonia, and the deep tendon reflexes were depressed. Mild truncal ataxia was observed, but there was no nystagmus. Read more »
