Normal Isn't Necessarily Optimal by Alvin B. Lin Medical DoctorHealth Maven Posted Wed 12 Dec 2012 3:00am Rather than make home visits yesterday, I substituted for another doc and worked in the UNLV Student Health Center.  It certainly makes for a nice change of pace, as I don't typically have a chance to provide counsel regarding hormonal contraception and prevention of sexually transmitted diseases.  However, I stopped dead in my tracks when ...

Older by Sandi W. Patient Expert Posted Mon 02 Feb 2009 10:59pm I was talking on the phone to R today, and she told me about her hometown best friend who has a terrible blood disease. What is it? I asked. I was pretty sure what she would answer. I was right: Polycythemia vera. Oh, I have that, I said. Mine is almost asymptomatic, except that I get pins and needles from taking a shower or bath with water that ... Read on »

Can you solve this case? by pathologystudent Posted Thu 29 Nov 2012 5:57pm Here’s another case in our series of unknowns (the last one is here ).

Take a look at the photo, and see if you can an ... Read on »

Mauled by a Student Nurse by Sandi W. Patient Expert Posted Mon 30 Mar 2009 3:18pm Alert readers will recall that Cancer Bitch has a rare blood disease that borders on cancer. It becomes cancer when plaintiffs' lawyers go after the people who allegedly caused it in their clients. Otherwise it's pre-cancerous. It appears mostly in men over 60, so she doesn't know what she did to get it, besides having a certain JAK2 gene muta ... Read on »
