It’s finally gotten chilly here, particularly in the mornings and evenings, although you can still walk around during mid-day in shorts and a t-shirt if you’re not a wuss. One benefit is that most of the Taliban flies have died or hibernated or whatever it is they do when it gets cold. This is a good thing for them because I’ve developed some sweet ninja skills in killing them. I don’t even use a fly-swatter anymore, just my hat. If I ever find myself stranded, I’ll have enough fly protein on the top of it to sustain me for at least a few days.
Despite the fair number of mortars launched at the base since I arrived here in July – though they’ve also thankfully really decreased now that it’s gotten colder and the traditional fighting season is over – I don’t think there have been any serious injuries from them on the base. Correlation is not causation, of course; my arrival here did not miraculously stop all mortar-related injuries. But the previous crew were in dining facilities when mortars happened to hit ... twice. Although one of the mortars didn't actually explode, it struck and killed a woman. The other one did explode and the doc here before me had to stick a needle in a kid's chest to decompress his lung right there on the dining facility floor. I’ve only seen a few people for mortar-related issues; more often than not the effects were more psychological than physical.
Traumatic brain injuries (TBI) have become a hot topic in our current conflicts. A mild TBI is a fancy term for a concussion. Better equipment, primarily in the form of IBA (interceptor battle armor, or “battle rattle”), and expeditious medical evacuation are probably keeping more kids alive than previously. Instead of dying from bleeding, they end up suffering from TBIs and as amputees. The ubiquitous use of IEDs instead of more “traditional” shoot-outs, as well as riding in armored vehicles, also puts them at higher risk for TBI.
Newer, better equipment can make a difference.
Blast injuries are divided into four classes: primary, secondary, tertiary, and quaternary. Primary blast injures are due to high pressure air waves, or shock waves, that affect parts of your body that are exposed directly to air, primarily your ears, lungs, and hollow organs of the gastrointestinal tract (thanks, Wikipedia). These shock waves often don’t leave any external marks, but they can blow out ear drums and bruise your lungs so that they fill with blood and/or excess fluid and can no longer exchange oxygen and carbon dioxide normally (that’s sort of important). This is called “blast lung” and is the primary cause of death among people who initially survive an explosion. It's sort of like drowning.
Secondary blast injuries are due to shrapnel that penetrates and damages someone’s body. Obvious enough. Tertiary injuries are due to the blast wind that throws a person against solid objects; the sudden deceleration causes injuries, including coup contrecoup injuries, which is the underlying source of TBIs; in other words, your brain bounces back and forth in your relatively solid skull and gets bruised. It’s science. It's inertia. The quaternary injuries are the olio (I recently learned that word from doing the crossword puzzle – it refers to a Spanish stew containing a hodgepodge of ingredients, kind of like Hairy Buffalo punch) of other injuries that occur, including flash burns and psychiatric injuries, e.g., PTSD. As I mentioned before, the psychiatric issues are the ones that I mostly deal with.

Coup contrecoup mechanism of injury, a.k.a. trying to reason with a stubborn Master Sergeant.
TBIs usually occur to our guys when they’re thrown against a hard surface, like the ground or a wall, or from getting bounced around into the heavily reinforced surfaces of the armored vehicles they operate. And although better helmets prevent direct penetration of projectiles into a kid’s head, they act like the body of a bell, which makes the kid’s head (and brain) like the bell clapper. I rode in a Humvee the other day, and I can tell you that everything about that vehicle was squat, heavy, and thick; and those are considered “lightly armored.” I almost gave myself a hernia trying to open and close the door. Because they’re heavy … and because I’m old.


They call it "getting your bell rung" for a reason.
An autopsy of one guy’s brain showed that it had changes similar to a much older and demented person, which is a common theme with many former contact sport athletes who’ve had their brains posthumously examined. A recent study suggested that even heading a soccer ball too much can cause measurable changes in cognitive function, particularly with attention, concentration, and memory; during residency one of our radiologists had a small brain bleed from heading a ball while playing non-competitively. There is some discussion “out there” about the death of football, particularly for young kids since their brains are still developing and potentially much more vulnerable.
It’s scary stuff. And it’s not even that you have to have full blown concussions. The syndrome is being called CTE, or chronic traumatic encephalopathy, and it involves multiple, repetitive occurrences of someone’s brain being sloshed around in and colliding against their own skull. The best recognized example is that of the “punch-drunk” boxer, the fancy name being “demenita pugilistica.” Malcolm Gladwell wrote an interesting article that I read a few years ago that does a good job explaining the situation.

One guy in our clinic had quite a bit of difficulty sleeping for a while after one of them landed a few hundred yards from our compound; he otherwise comes across as a pretty grizzled Master Sergeant type. Another girl I saw had some very mild barotrauma (pressure injury) to her ear drum. She was driving outside with the window slightly rolled down when the vehicle-born IED I mentioned a while back went off. Kind of freak thing, though, cause she was really nowhere near the actual explosion. But mostly it just scared her and I listened to her cry for a little while as she told me about it.
Another guy I saw was nowhere near that very same shell that tore up that other kid’s truck, but he just happened to be outside playing basketball when it hit, and it was really loud. I went through the whole question and exam thing with him, but there really wasn’t anything obviously wrong. I asked some more questions about how he was managing it mentally and emotionally. After some hem-hawing, he finally explained that what concerned him most was that he was talking with his wife later that same evening. Apparently, she Skypes “provocatively” with him, and he couldn’t get an erection. And that’s what really freaked him out – his boner wasn’t working and he was worried about whether things would be functioning correctly when he returned home in a few weeks.
I told him that particular effect is probably part of his acute reaction to stress, that the "fight or flight" response shuts down some of the body's less essential functions to immediate survival. I then reassured him that I thought things would probably go back to normal soon and he should be just fine when he gets home. I’ve seen him around the compound a few times since and he reported that things have "straightened out" for him.
I learned this from a urologist with whom I was working one day during residency. He was very excited about the results of a study he just read. He asked me several times if I’d write him a script for his “knee pain"; more like his "wee-knee" (I know, not quite as bad as the “punch-uate” pun, but still pretty bad). I assured him that, for all intents and purposes, 35 seconds (5 sec x 7) probably wouldn’t make an appreciable difference for his wife.
Maybe the strangest request for boner pills occurred last year when I saw a guy asking for a refill on Levitra. He came in just before leaving to return to the the States, so I asked why he waited until the last minute to make an appointment. He explained that he was going on emergency leave. He only just found out that morning about a family member who passed away, and he was leaving later that evening to arrive and attend the funeral. Boner pills for a funeral?
Chazz Reinhold: Grief is nature's most powerful aphrodisiac.
John Beckwith: I crashed a funeral today ... It wasn't my idea, I was basically dragged to it ... I went with Chazz who you forgot to tell me is totally insane. He also might be a genius because it actually does work. He's cleaning up.
