November 2021: Fleshy Lumps on the Scalp
Nausea and body aches. Probably COVID. Unvaccinated. Definitely COVID. After all, what else are we seeing?The 20-something young man was eating and talking on his phone. He passed the look test. His vitals were pristine, but he regaled me with myriad symptoms he had had for months. He hadn't taken any medicine. I was at a loss for what drove him to come to the emergency department. He thought for a minute and said, "I want to know why I have all these."He pointed to a spot on his head, which drew my attention to a fleshy lump. Then he moved his hair around, causing others to appear. "You can feel lots more,&...

3D Printed Titanium Implants for Severe Spinal Deformities
Most medical implants are manufactured in quantity to cover large groups of people suffering from specific diseases. Those with rare conditions are often left out, but 3D printing, also known as additive manufacturing, now allows for the production of bespoke devices designed exclusively for individual patients. While 3D printing technology has advanced significantly over the past few decades, significant clinical and legal challenges exist that prevent its wider adoption in many spheres of medicine.
A diverse group of engineers, surgeons, and regulatory experts have been working together at the University Medical Cente...

Tuberous Sclerosis : Case Report
DiscussionTuberous sclerosis is an autosomal dominant neurocutaneous syndrome characterized by various abnormalities, including multisystemic hamartomas. Also known as Bourneville disease, named after D ésiré-Magloire Bourneville, the French physician who discovered the potato like appearance of cortical lesions in the brains of patients with this condition.Tuberous sclerosis is the second most common phakomatosis behind neurofibromatosis type 1. It has a prevalence estimated to be 1 in 6000. App roximately one third of cases of tuberous sclerosis are familial the other two thirds of cases are sporadic and due to spontan...

Best Post of January 2018: Choroidal ganglioneuronal hamartoma in an NF1 patient
The next in our " Best of the Month " series is from January 30, 2018:Thanks to Dr. Ahmed Gilani (pediatric pathology fellow at the University of Colorado) for providing me with slides of an enucleation specimen from a patient with Von Recklinghausen Neurofibromatosis (NF-1). The specimen exhibits a region of choroidal expansion with hamartomatous neuroglial tissue. Distributed throughout this choroidal expansion are non-pigmented ovoid bodies, which have a delicately laminated appearance reflecting the presence of concentric Schwann cell processes. One might conceive of these choroidal expansions as cousins of iridic Lisc...

Why does hair turn gray?
Follow me on Twitter @RobShmerling
If you look at photos of President Obama taken before he ran for president and since he left office, you’ll notice a distinct difference: where there used to be only dark brown hair, there is now far more gray than brown. It seems that the stress of running a country would turn any person’s hair gray. But is stress really to blame? And why does hair turn gray, even for those of us who don’t have jobs quite as stressful as President of the United States?
Stress doesn’t actually turn hair gray. In fact, hair doesn’t actually “turn” gray. Once a hair follicle produces hair, the...

An Exploration of Mechanisms of Hair Greying, but not Yet Linked to Aging
This research is an example of the way in which both the mainstream press and research publicity materials are sometimes quite terrible. The researchers involved have explored some of the cellular biochemistry that is necessary to the pigmentation of hair. They demonstrate, as you might expect, that sabotaging these mechanisms results in grey hair. What they have not yet accomplished is to show that aging has an impact on the specific mechanisms examined in this research. Maybe it does, maybe it doesn't. While the research looks like a promising lead, all things considered, age-related graying of hair might well be caused ...

Neurofibromatosis-I
Patient with multiple cutaneous lesions on MRI brain shows evidence of thickened and moderately T2 hyperintense optic chiasma with moderate post gadolinium enhancement anteriorly extending till the orbital apex. This may indicate optic glioma. There are areas of T2/FLAIR hyperintensity in the bilateral mesial temporal regions, right globus pallidus region and right pontomesencephalic region, with no significant enhancement, Possible hamartomas. These findings along with cutaneous findings described could indicate diagnosis of Neurofibromatosis I. Advised clinical correlation. The criteria for the diagnosis...

Laboratory Abnormalities and Pyloric Stenosis
The classic clinical presentation of infantile hypertrophic pyloric stenosis (IHPS) is an emaciated 3- to 6-week-old infant who has been experiencing immediate postprandial, nonbilious, projectile vomiting over a period of weeks. The infants remain hungry and demand to be re-fed after vomiting. Caucasian, full-term boys (4:1 to 6:1) tend to present with this condition most frequently, and these patients tend to be firstborns.
An olive-sized tumor can be felt to the right of the umbilicus, and this may best be palpable immediately after the infant has vomited. Visible peristaltic waves may also be noted. The infants are typ...
