What You Need to Know About Prostate Cancer

It's MoVember or No-Shave November and I've shaved off my beard to grow it back during this month to raise awareness -- and cash -- for men's health issues.

Seems like a good time to give the Red Triage treatment to some of these health issues.

So here goes our first What You Need 2 Know (WUN2K?)

How Do You Say It? It is pronounced ProsTATE not prosTRATE. To be prostrate is to lay flat on the ground face first in front of someone either because you are being arrested or really, really into religion. ProsTATE is a greek word meaning protector or guardian. Which allows for this fun sentence: "The prostate, prostrated himself before his King."

Why Do We Need It? The prostate is a gland that produces a liquid that protects the sperm from the acidic environment of the vagina.
This -- and the fact that prostate exams are conducted with a doctor's finger in the rectum -- make it hard to talk about the prostate at dinner parties.

Why It Causes Problems: This is a gland that wraps around the urethra just below the bladder. So if it swells up for any reason, it makes urinating difficult. It's not really in the penis, but messing around with it through surgery can affect a man's ability to have sex and urinate. These are two things men really like to do.

Can We Live Without It? Sure, it is one of the glands a guy could get along without. It would be harder to make babies, but not have sex. The problem comes in getting rid of it. It is located in a spot where a lot of the blood vessels and nerves running to the penis are also located. As noted above, collateral damage is possible and can lead to problems having sex and urinating.

What is Prostate Cancer? Think of cancer as runaway evolution starting with one cell that has an error in its programming. It reproduces like crazy and makes more bad copies. These cells can sometimes spread to distant parts of the body. Different cells make different kinds of cancer and those cancers cause different kinds of problems and symptoms. They act differently. Some causes big problems, pain and death. Some cause minimal problems and there are probably cancerous growths that are never discovered and are handled by our bodies defenses.

Nowhere is this more evident than in prostate cancer. There are different types - a slow growing kind and more aggressive, fast growing kinds. It has been said that most of us men - if we live long enough -- will probably die WITH prostate cancer, but not FROM prostate cancer. That's because the slow growing kind of prostate cancer is much more common. This kind does not spread to other parts of the body or mutate like the more aggressive types.

 Lies, Damn Lies and Statistics:
Prostate cancer is the most common cancer in men.
It is the second leading cause of cancer death for men in the United States.
An estimate 238,590 men will be diagnosed this year.
Approximately 29,720 will die from it.

Survival rates are good with 98 percent surviving 10 years after diagnosis and 93 percent surviving 15 years after diagnosis. However, while death from prostate cancer is declining among all men, it is still twice as high for black men than white men.  (source, American Cancer Society via Cancer.net ) Black men have a high incidence of prostate cancer and tend to get the more aggressive form. 

 Read More About Testing
Testing, Testing: This is an area where there has recently been controversy. A test for Prostate Specific Antigen has been around for years, but the test is not as specific to prostate cancer. Cancer cells in the prostate spit out large amounts of this protein, but PSA is also found in higher-than-normal levels in men other various prostate conditions, such as benign prostatic hyperplasia (BPH, an enlarged prostate) and prostatitis (inflammation or infection of the prostate). Because it is an easy test to add on to routine blood work, many men may have had this test and not even know it. 

So, if the PSA level is high, it may indicate that a man has an aggressive prostate cancer that has yet to become symptomatic.

Or it might not.

Here's what the American Society of Clinical Oncology has to say:
 In some situations, PSA testing finds aggressive prostate cancers early and save lives. However, it is not easy for a doctor to predict which tumors will grow and spread quickly and which ones will grow slowly. In some situations, men who have a prostate cancer that will never cause them harm may be discovered, and this discovery means these men will undergo additional testing and treatments that turn out to be unnecessary. These tests and treatments put a man at risk for infection, impotence, incontinence, and rarely, death. Each man’s risk of prostate cancer and acceptance of potential side effects is different.
So if you are over 50, you should talk with your doctor about whether PSA testing is appropriate and if the test comes back positive, what the plan will be. New guidelines allow doctors to take a "watch and wait" approach, rather than initiate invasive testing. (For more on this, see earlier post on Medical Testing.)

How Do I Not Get This:
Don't get old (80 percent of all prostate cancer is diagnosed after age 65) and eat a low fat diet with lots of fruits and veggies. Will that prevent prostate cancer? We don't know but it can't hurt and some research seems to point in that direction.

Don't go crazy with supplements like Selenium and Vitamin E. The SELECT study looked into these and found that they not only did not prevent prostate cancer, but may have caused more harm than good.

This seems to be a type of cancer that doesn't rely on genetic inheritance, although if you have close family members (son, brother, father) that were diagnosed at a young age, your chances are higher of developing the disease.

The Jury's Still Out: One area of research is a link between vasectomies and prostate cancer. One study in 1983 showed an increased risk, however subsequent review has shown that the link between the two is very small and the increase in risk if they are linked, is also very small. Size does matter. Get the vasectomy.

Do We Have Any Evidence That Tamiflu Works?

The threat of Pandemic Influenza remains on the horizon with the latest evidence showing that H7N9 kills a little over one third of all infected. That's more lethal than the 2009 swine flu

While H7N9 has stalled for the moment, if it or a new variant arises, are we prepared to fight it?

Risk factors are all in place that make it likely we'll see a virulent flu variant in the near future. 

Moreover, as the MERS news coming out of Saudi Arabia ... or not coming out for that matter ... reminds us, other types of pandemics are brewing and are waiting to be spread. 

Thus, it's always good to be restocking our tool chest, and sharpening our knives to make sure we are vigilant and ready when the next one comes. The trouble is, we don't have a lot of tools. (See my earlier post: Poor Tools for Fighting Flu)

Tamiflu is the drug of choice for high risk folks presenting with influenza and some are even proscribing it as prophylaxis for flu exposure. There have been lot of studies as to whether it is actually effective - the most rigorous controlled study showing that it reduces the duration of the disease, but not the severity. 

Actually, one study found that the duration of the disease symptoms is reduced on average of 20 hours. Moreover, in most otherwise healthy patient populations, using the drug caused little reduction in hospitalization or complications when compared with placebo in several studies.

In other countries, there has been more debate about whether to give a drug that hasn't been shown to be all that effective. That debate has been fueled by the fact that the drug company won't release the results of all of its studies. 

This is a brewing into a big fight in the UK because that country has stockpiled more than $800 million worth of Tamiflu. 

Last week the editor of the British Medical Journal told a parelamentary committee that there is little evidence that Tamiflu is better than cheap painkillers. Tamiflu's maker, the Swiss company Roche, has promised to release the results of its own clinical trials, but has so far failed to do so. 

Bad Pharma author, Ben Goldacare in the same committee hearing told the ministers that this is part of a larger problem with pharma studies -- not all the results have to be released. Thus drugs companies tend to release only the clinical trial that support the effectiveness of their new drug, while keeping negative results hidden away. 

This isn't illegal or even a new problem. 

"Tamiflu is just one small microcosm," Goldacre told the ministers. "One of the things that is very striking is at no stage the Roche break the law, because the law is broken." 

Roche has released only about 40 percent of the 137 clinical trials it conducted. Other drug companies have had similar issues and in recent years there have been recalls of drugs in the United States where early trials pointed to negative outcomes.

So what is the latest on whether Tamiflu is worth the money - or the risk of side effects?

New Scientist reported a round up of the debate pointing to a study of the 2009 H1N5 outbreak. In that case, Tamiflu - given early - reduced the death rate for hospitalized patients by nearly half. A meta-analysis looking at more than 160,000 patients in 37 countries was published in February showing that the drug is effective and saves lives. 

Meanwhile, the Centers for Disease Control addressed those underwhelming earlier findings that showed the drug only reduced the duration of the disease by only 21 hours. 

The CDC pointed out the Cochrane Collaboration research did not look at the high risk populations that need the drug, but rather tested it on seasonal flu cases in otherwise healthy populations.  Tamiflu seems to help prevent the development of pneumonia, which is the killer when it comes to Pandemic Flu in high risk populations.

In other words, we should be giving Tamiflu to high risk populations with pandemic flu to prevent lethal pneumonias, not handing it out to healthy populations because they demand it when you give them a diagnosis of seasonal flu.

The Increased Use of the ICU

We are using our ICU's more often than we have in the past, according to a new study. As published in the Academy of Emergency Medicine, George Washington University researchers found a 50 percent increase in Intensive Care Unit admissions between 2002 and 2009. 

As the patient's get older, we are utilizing intensive care more often. The group with the largest jump in ICU admission was those over the age of 85 years. That isn't likely to surprise, given the aging population in the United States.

Yet, the recent study that highlights an increase in hospice admissions only after intensive  and expensive ICU care in the last few days of life highlights the fact that we are still aggressively treating patients in the last chapter of their lives. That Journal of the American Medical Association study appeared with an editorial calling for an end to aggressive hospitalization in end of life care by increasing planning and communication between patients, families and doctors prior those final days. 

The article also notes that patient's also spent up to 5 hours in the Emergency Department waiting to get into the ICU. 

 "Studies have shown that the longer ICU patients stay in the emergency department, the more likely they are to die in the hospital," Pines said. "Better coordination between the emergency department and ICU staff might help speed transfers and prevent complications caused by long emergency department waits," he said.

Ummmmm ... I don't think it is interdepartmental coordination and ED wait time that is increasing these critically ill patient's mortality rate. Might have something to do with the fact that they are sick. 


Patient's are often stabilized the ED prior to transfer to the unit. Often times our ICU won't even take the patient until they are stable for transfer, have all their drips hanging and they have a tube in every orifice. Moreover, with increased admissions, there are increased demands on staffing the ICU. We retain core staffing in the Emergency Department even when our census is low because our patient population in the Emergency Department can change in a heartbeat. Many times we've seen the ER go from empty to full in just a matter of minutes. 

ICU's however, often call off staff when their population is low. Therefore, we are often waiting for a nurse to come in to take our patient. That doesn't mean that there couldn't be better coordination between the Emergency Department and the ICU. Those two departments attract very different personality types.

However, I doubt that lack of coordination between the ICU and the ED that is the primary reason for the increased mortality of patient's needing intensive care in the last years of their life. It may have more to do with the need for better communication between providers and patients and families before those days arrive.

Visualize This: When Neutrophils Attack!

A million years ago, when I was at Washington State University, one of the many jobs I held to pay my way through was working in the counseling psychology department editing grants and research papers for the researchers there. It was a great way to be exposed to all kinds of interesting research.

One of the papers that caught my imagination was by Arreed Barabasz - a researcher who is an expert in hypnosis for medical problems. At the time, he was also using sensory deprivation tanks. He didn't call them sensory deprivation tanks, they were Restricted Enviroment Sensory Tank since Altered States and LSD users had given them a bad rap. Anyway, Barabazs' idea was that floating in this darkened tank of body temperature salt water would provide a better environment for self hypnosis.

The paper I was editing was all about using self hypnosis to increase white blood cell counts. The visualization used while in the tank was to imagine white blood cells multiplying and ganging up on the invading bacteria or virus. The idea was to think of sharks chasing them down and devouring them.

This idea of self-hypnosis and visualization allowing one to have a positive increase on one's own cell count really got my mind going. I even wrote a research proposal for one of my classes based on his research. I've told lots of people about this research when they were facing illness, hoping the visualization would help and encourage them. I figured, it couldn't hurt. I've even tried it myself, but it has always been hard to describe what white blood cells look like when they are hunting their prey.

Then I came across this:

The footage is old, but it is a classic. Watch that neutrophil track down that bad guy and eat him. Love it. This will be my new mental movie the next time I get a runny nose.

As for the research, it was 20 years ago and I haven't heard much about it since. My guess is the initial positive results didn't pan out, or they were confounded by the fact that REST environment greatly reduced stress, which helps immune response. If you want to learn more about how the immune system works, you can check out this video:


If you need me, I'll be in my sensory deprivation tank.

Did You Check A Blood Sugar?

By Penarc (my own picture) [CC-BY-SA-3.0 (http://creativecommons.org/licenses/by-sa/3.0)], via Wikimedia Commons
A few years ago, I had a call about a patient coming in by ambulance as a stroke alert. Right side was flaccid, pt was aphasic. She had an the history of an old CVA some years prior, but after rehab, family said she no longer had deficits. I took the HEAR report and after listening to the patient's condition, I asked "Did you check a sugar?"
           There was a moment of radio silence.
 "We'll have that for you on arrival," was the response.
          On arrival, I was told her capillary glucose at 24 mg/dl. An Amp of D50 started resolving her neuro deficits.
       By the time she left, she walked out the door under her own power, laughing, talking and relieved that she wasn't facing a future of long and arduous stroke rehab.
      This was just one of several cases I've seen over the years of hypoglycemia masking as a stroke. That's why protocol is to check blood sugar on every patient with an altered level of consciousness - regardless of diabetic history.
       Yet, we often miss it. Sometimes we are more focused securing and protecting an airway, or getting IV access - when a quick check of the blood sugar with a finger stick could allow us to quickly identify and correct the underlying cause of the altered level of consciousness.
        Hypoglycmia can present in patients with no diabetes history.
        Alcohol can cause alterations in blood sugar, and too low or too high blood sugar can present as drunkeness.
        Unilateral deficits don't often trigger thoughts of hypoglycemia in our minds. Yet the brain needs glucose just as much as it needs oxygenated blood to function. Cut off the glucose and brain cells can act just like they are experiencing ischemia.
        Yet why would a patient present unilateral symptoms or hemiparesis if the whole brain is running low on glucose?
         In my experience, the patients I've encountered with this presentation have often had some sort of ischemic event in their past. Collateral circulation may have allowed the brain to recover full function after the event, but starving the brain can affect the weakened tissue or impaired circulation.
         What is collateral circulation? Think of a stroke as a wreck on the freeway, blocking traffic to a certain area of the brain. Collateral circulation refers to the smaller blood vessels that can be used as a detour when the freeway is blocked. Traffic - blood flow - goes to the local roads. In some circumstances, the body may even generate new blood vessels.
          We have known about collateral circulation for some time, but we are still learning about how it works, and how we can use it to improve outcomes.
          What about younger populations?
          Newborns of course have limited reserves and can get hypoglycemic far too easily -- particularly if the mother had high blood sugars while pregnant. If a newborn goes too long without eating, hypoglycemia can present quickly. Sepsis, too, can cause a newborn to burn through its sugar reserves.
         The first time you discover a type 1 diabetic, he or she is in DKA, with symptoms that can often be mistaken for viral illness or other conditions. Low blood sugar can cause seizures and so you should always check a sugar when you find a patient in a postictal state.
          Bottom line, a finger stick blood sugar is an easy thing to check, a cheap test to do and may diagnose a easily treatable condition. So whenever a patient comes my way with altered mental status, don't be surprised to hear me ask "Did you check a blood sugar?"

The Dope on SOAP charting

For some reason, SOAP charting seems to get people confused. It is an easy way to break down the information you are presenting if you do it right. The trick is to tell the story that allows the history to be separate from the observable findings. Why? Because what dispatchers and patients and families tell us, may or may not be what's actually going on.

S Subjective - things people tell you.

Little Things Mean A lot

One night when I had just started working in the big city ED, we had a ambulance come in the wee hours of the morning and the last hours of a long 12 hour shift.

 The call was for "leg pain" in a 48 year old female. When she rolled through the door, something didn't seem quite right. She appeared to be in excruciating pain, but EMS said her heart rate was brady at 54. Increasing pain should increase the heart rate. She also just didn't look well. I called for a 12 lead EKG before she was even off the gurney and started an IV and labs. 

A few minutes later, the ED doc held the EKG in his hand. "Who ordered an EKG for leg pain?" I explained my decision. Turns out she was in new onset of third degree heart block. 

We've had cases where nurses have caught heart attacks based on nothing more than a hunch. I've seen cases where present like a stroke and a blood sugar reveals that they were really just hypoglycemic. 

Little things, can protect you from missing the right diagnosis, the right course of action. 

Just had another case like this the other night. Call was for a 37 yoa male near syncope while playing pool in a bar. Hx of vertigo in the past but pt states "this is different." The Medic got the 12 lead = AFIB with RVR 170 - 190 with no prior history. If you think, "should I get a 12 lead/check a blood sugar" the answer is almost always yes.

Here's a good article on how doing little cheap things can reduce the risk of big failures. It's based on the new book Antifragile, which I haven't read yet - but based on this article, I think I'll check it out. 

"Thus the decision to withhold the 12-lead is in Taleb’s view, a fragile one. If you lose, you (and the patient) can be broken. You want always to avoid the state of fragility. You want to be antifragile. Your gut may tell you it’s not cardiac, but in this situation where the possibility of failure exists, having a redundant system like a 12-lead provides you protection. At a low cost of doing a 12-lead, you prevent a catastrophe – missing a STEMI.
Minor exertion versus a patient’s death. The potential gain and the potential loss from the bet that it is not cardiac are not equal. Low upside if you are right, big downside if you are wrong."
