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 »

On the US News & World report website, Dr. Kenny Lin writes as a physician and a concerned observer about “Dangers of Incidentaloma: Why To Think Twice Before Getting a CT Scan.”
It’s an important issue. Give it a look.
Lin’s blog, “The Common Sense Family Doctor,” is also worth visiting. Recently he cited one of my alltime favorite essays, “The Last Well Person,” by Dr. Clifton Meador, who wrote in 1994:
“The demands of the public for definitive wellness are colliding with the public’s belief in a diagnostic system that can find only disease. A public in dogged pursuit of the unobtainable, combined with clinicians whose tools are powerful enough to find very small lesions, is a setup for diagnostic excess. And false positives are the arithmetically certain result of applying a disease-defining system to a population that is mostly well. … If the behavior of doctors and the public continues unabated, eventually every well person will be labeled sick. Like the invalids, we will all be assigned to one diagnosis-related group or another. How long will it take to find every single lesion in every person? Who will be the last well person?”

There was an interesting study published this week in the journal Radiology:
Rising Use of CT in Child Visits to the Emergency Department in the United States, 1995–2008 (Abstract)
The results are not surprising to anyone who has been working in medicine in the US over the last fifteen years. Basically, in 1995, a kid visiting the ER had a 1.2% likelihood of getting a CT scan, and by 2008, that number was 5.9%.
I had written about this general phenomon not too long ago, in defense of the general increase of CT utilization in the ER, largely on the basis that CT is a better tool: it provides diagnoses in a rapid and timely manner, and excludes many potential life threats, saving lives and mitigating malpractice risk. That was largely relevant to the adult population, though, and kids are not, as they say, just little adults. The increase in scanning children is more dramatic, especially given the generally lower incidence of disease in kids compared to adults and the chonrically ill. 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 »

By Richard C. Hunt, MD, FACEP
Centers for Disease Control and Prevention
A 17 year-old athlete arrives on the sideline, at your office, or in the emergency department after hitting her head during a collision on the sports field and is complaining that she has a headache and “just doesn’t feel right.”
Can she return to play? If not, when can she safely return to school, sports, and to her normal daily activities? Does she need immediate care, a Head CT or MRI, or just some time to rest?
Do those questions sound familiar?
Each year thousands of young athletes present at emergency departments and in the primary care setting with a suspected sports- and recreation-related concussion. And every day, health care professionals, like us, are challenged with identifying and appropriately managing patients who may be at risk for short- or long-term problems.
As you know, concussion symptoms may appear mild, but this injury can lead to significant, life-long impairment affecting an individual’s ability to function physically, cognitively, and psychologically. Thus, appropriate diagnosis, referral, and education are critical for helping young athletes with concussion achieve optimal recovery and to reduce or avoid significant sequelae.
And that’s where you come in. Health care professionals play a key role in helping to prevent concussion and in appropriately identifying, diagnosing, and managing it when it does occur. Health care professionals can also improve patient outcomes by implementing early management and appropriate referral.
As part of my work at CDC, and as a health care professional, I am committed to informing others about CDC’s resources to help with diagnosing and managing concussion. CDC collaborated with several organizations and leading experts to develop a clinical guideline and tools for the diagnosis and management of patients with concussion, including:
