Strange Compulsion

Pica is a medical term that refers to people who eat substances that are not nutritious like clay, dirt, paper or starch.  Lithophagia is the eating of rocks or pebbles.  The Xray above is from a 48 year old homeless man who came to the emergency department with abdominal pain, constipation and intermittent blood in his stool for 2 weeks.  The abdominal Xray showed small radio-opaque pebbles and gravel that the patient admitted eating over the last 9 months.  He believed that "God might turn it to bread in his belly."  He was given the diagnosis of nonspecific delusional disorder.

The patient underwent a purge with polyethelene glycol electrolyte solution.  (It is the same solution that is used for bowel prep before a colonoscopy).  Some of the pebbles had to be manually removed under general anesthesia.  His symptoms improved and follow-up Xray showed compete removal of the stones.  Unfortunately the patient was lost to follow-up after discharge from the hospital.

Geophagia is the eating of clay or dirt and it is not uncommon in the setting of famine and poverty.  There have only been 2 cases of lithophagia reported in the medical literature.

I can't imagine what would make someone look at a pebble and say, "Mmm, those looks good. I think I will eat ten or twelve." On the bright side, dirt and rock eaters don't have to worry about iron deficiency.

There is a tv show called "My Strange Addiction" which features a lot of these people. One woman ate a couch (over time). They've had eaters of chalk, clay pots, crayons, laundry detergent - fascinating.
Can you imagine being the parent of a child with pica? It's scary enough to think that a small child might accidentally try to eat something they shouldn't but this disease actually makes them seek it out!
Avoid these inferior product. These are harmful for your health.

scintillating scotoma

Nothing like experiencing a medical condition first-hand to really help a doctor understand it from the patient's point of view.  After all these years, I had my first (and hopefully last) scintillating scotoma while sitting on the couch playing "words with friends" on my ipad and watching TV.  A scotoma is a partial loss of vision in a normal visual field.  Scintillate is flashing, sparkles.  Put them together and you have moving, flashing sparkles with a blind spot in your eyes.

This visual aura was first described in the 19th century  by a Dr. Hubert Airy who had migraine headaches.  The visual sparks and flashes are in a zig-zag pattern and they can precede a migraine headache or occur without any pain.   The scotoma affects both eyes and closing one or the other does not make it go away.  Sometimes the term "ocular migraine" or "retinal migraine"  are used to describe this phenomenon but these involve only one eye, not both.  The terms are often …

Do Doctors Make Too Much Money?

An article in theNew York Times says the reason health care costs are so high in the United States is because doctors are paid too much. I saw that and my eyes bugged out. I just came home from a meeting with physicians and hospital administrators and the entire meeting was spent discussing the financial challenges physicians face in keeping their doors open to see patients. The goal of this meeting was to keep health services in that community so patients will have someone to care for them. Not a person in the room would agree that the doctors earn too much.

Physicians paid too much? Lets break that down. A doctor spends a minimum of 11 years in education and training after the age of 18. Many are in training for 15 or more years. They are living on student loans and contributing zero to their family's income until the residency years. At that time they earn less than minimum wage if you factor in the 80-100 hour workweek. When a doctor emerges from training (and believe me…
