Microbiome topic of the day: radiation therapy and the microbiome
Just saw this interesting story in the Observer: Cancer scientists to classify gut bacteria to prevent the side-effects of radiotherapy | Science | The Observer.  It discusses an effort to give more consideration to protecting and / or repopulating the microbiome in relation to radiation therapy.  I think this is critically important.  I want to note - people should give some credit to DARPA for being ahead of their time on this issue.  I went to a workshop in 2004 organized by Brett Giroir and Manley Heather.  The topic was "Radiation Protection" and one of the points of discussion was the gu...

It Helps To Know What Watchful Waiting Really Means In Prostate Cancer Treatment
News reports covering a prostate cancer study this week in the New England Journal of Medicine have all pretty much come out with the same message: men diagnosed with prostate cancer who had radical surgery did much better than men who were assigned to "watchful waiting" after they were diagnosed. But guess what? There's a critical fact that seemed to be missing in much of the coverage I saw. And that fact is this: the men who were given the "watchful waiting" as described in the study never received any curative treatment. Let me repeat: No curative treatment. That is a much different approach to watchful waiting than we ...

Decreasing RT dose to bilateral IB lymph nodes results in better patient-reported salivary function
For head and neck cancer patients undergoing radiation therapy, a reduction in the amount of radiation treatment volume to the submandibular (level IB) lymph nodes resulted in better patient-reported salivary function, according to research presented nowadays at the 2014 Multidisciplinary Head and Neck Cancer Symposium. The study results also found substantial reductions in radiation dose towards the salivary organs, and good local regional control.

Medical sources of electromagnetic interference (EMI) to pacemakers / ICD
(implantable cardiovert-defibrillator) include: a) Electrocautery: Interference can be reduced placing the indifferent electrode as far away from the pacemaker and better still by using bipolar cautery instead of unipolar cautery. b) Radio-frequency ablation c) Radiation therapy d) Electrical nerve and muscle stimulators e) Dental instruments f) Spinal cord and deep brain stimulators g) Defibrillators h) Capsule endoscopy i) Electroconvulsive therapy j) Magnetic resonance imaging (Source: Cardiophile MD)

A Constricting Diagnosis
The heart, vasculature, and blood (pump, pipes, and fluid) work together to meet the metabolic demands of the body. End organs and tissue are not adequately perfused when the system fails, leading to injury and deranged physiology. Understanding the hemodynamic relations in normal cardiovascular physiology and how it changes in pathologic conditions helps us make the correct diagnosis and implement the right treatment.   Physical examination can provide indirect clues to hemodynamics, though invasive evaluation has been the traditional gold standard. This can include arterial and central venous pressure measurements, ca...

Healthcare Update Satellite — 11-14-2013
See more news from around the web over at my other blog at DrWhitecoat.com An example of the downside to government-run health care. Patients in Venezuela can’t get proper medical care. 300 cancer patients were just sent home when supply shortages and “overtaxed equipment” made it “impossible … to perform non-emergency surgeries.” 70% of the radiation therapy machines are inoperable. Basic supplies such as needles, syringes, medications, operating room equipment, X-ray film, and blood needed for transfusions are all in short supply. There is no anesthesia for elective surgery. Patients can no longer get organ d...

A physician expert witness speaks out
I have been actively engaged in the clinical practice of radiation oncology for the last 40 years, and over the last 10 years have been asked to participate as a radiation oncology expert witness in a variety of medical malpractice cases. Radiation therapy, together with surgery and chemotherapy, is one of the major cancer treatment methods. It is estimated that 50-60% of all cancer patients seen in the USA receive treatment with radiation at some point in their disease trajectory. For 2012, the American Cancer Society estimated 1.6 million new cases of cancer, and that translates to upwards of more than 800,000 patients...

MKSAP: 38-year-old woman with increasing fatigue and weight gain
Test your medicine knowledge with the MKSAP challenge, in partnership with the American College of Physicians. A 38-year-old woman reports a 3-month history of increasing fatigue and weight gain. She underwent transsphenoidal surgery 4 years ago to remove a nonfunctioning pituitary macroadenoma, followed 4 months later by radiation therapy because of residual tumor. She started taking hydrocortisone 14 months ago after adrenal insufficiency was diagnosed. The patient developed amenorrhea 1 year ago and began taking an oral contraceptive. Medications are hydrocortisone, norethindrone with ethinyl estradiol, and a multivita...

Radiation Dose Linked To Cardiac Risk In Breast Cancer Patients
    In the past, cardiovascular risk has been linked to the radiation dose received by breast cancer patients. Now, a new study published in JAMA Internal Medicine attempts to calculate the cardiac risk of breast cancer patients today undergoing current radiotherapy protocols.   David J. Brenner and colleagues calculated the excess cardiac risk for 48 patients who received radiotherapy at New York University. They estimated the 20-year cardiac risk based on baseline risk and patient-specific mean cardiac radiation dose. Cardiac dose was significantly higher in patients with left-sided radiotherapy. These...

Personalized Medicine Revolution Will Require Revolutionary Changes In How We Care For Cancer Patients
I attended a meeting in Washington this past Wednesday that got me to thinking about the fact that as we revolutionize cancer research and treatment, we are also going to have to revolutionize cancer care. And that  may prove to be an even more daunting task than finding new treatments for the disease itself. The meeting was sponsored by a collaboration called "Turning The Tide Against Cancer". The organizers brought together experts from a variety of disciplines ranging from insurance companies and economists to advocacy groups and highly regarded cancer specialists to discuss policy solutions to support innovation i...
