Researchers in Iowa have discovered what makes a lion or tiger roar so effectively. Apparently, there is a layer of fat within large feline vocal cords that makes the vocal cords especially prone to vibrate easily with minimal exhalation effort.
What import does this have to humans?
Well, there are patients who have a very weak voice due to vocal cord atrophy as well as vocal cord paralysis. Standard interventions include voice therapy as well as surgical procedures using an implant or injectable material in order to “bulk” up the vocal cord.
In fact Read more »

I suffer with herniated lumbar disks. L4-L5 bulges and ruptures on occasion. If you catch me on the wrong day I have a little curvature to my back representing the spasm that makes me miserable.
I saw an extremely well-referenced orthopedic surgeon in consultation recently. But through the course of my visit he never touched me. We spent an extraordinary amount of time examining my MRI. Together in front of a large monitor we looked at every angle of my spine with me asking questions. I could see first hand what had been keeping me up at night. I could understand why certain positions make me comfortable. What we drew from those images could never be determined with human hands. In my experience as a patient, I consider it Read more »

The basic function of the human nose is to warm and humidify the air before it reaches the lungs. Because of the wide variation of human habitats from the polar cold and dry air to the equatorial hot and humid weather, one would expect the nose to accommodate to these climate extremes accordingly through evolutionary pressures.
In essence, logically one would expect the nose to change shape to enhance time that air is in contact with the warm and moist nasal interior in cold and dry climates compared to the opposite environmental extreme.
German scientists evaluated this hypothesis through Read more »

It’s all too easy to try and quantify everything in medicine. We are, after all, under the widely held delusion that medicine is like physics. A thing that follows fixed, predictable mathematical models. A thing reproducible if only algorithm A is followed for this disease and algorithm B is followed for that disease.
This belief is also held by the government, which doesn’t want to pay for readmissions or mistakes. Because it is believed that all things in medicine can be known from an exam, some labs, some tests, and some studies.
Nevertheless, things happen. Disease are transmitted in public or by families. Medications don’t always work. Bodies change. Bodies age. Humans are non-compliant. Humans are suffering from physiologic phenomena we can’t yet comprehend. Viruses are synergistic with other diseases.
The immunity of our patients is affected by their happiness, their diet, their work history, their family. The algorithms necessary to make medicine anything like physics would be mathematically beyond comprehension. Read more »

If there is a central theme to this blog, it is this: Medicine is a human thing.
On the Facebook page of my podcast, I recently asked for readers to tell me some of the “war stories” they have from the doctor’s office. What are some of the bad things doctors do wrong? I quickly followed this with the flip side, asking readers to comment on the best interactions that they’ve had with their doctors.
The response was overwhelming, and equally quick to both rant and rave. They told stories about doctors who didn’t listen, explain, or even talk with them. They told about arrogance and disconnectedness from the people from whom they were seeking help. They also told about doctors who took extra effort to listen and to reach out in communication. They talked about doctors who genuinely seemed to value them as humans. Read more »
