The stroke of God’s hand on Carol Barnes

The British newsreader Carol Barnes has sadly died, from ‘a stroke’, and the actress Samantha Morton has just revealed a stroke as the reason for her 18 month disappearance from Hollywood.

In English medical vernacular, the term ’stroke’ is usually used to describe a catastrophic Cerebro-Vascular Accident (CVA). In more common English, that means something really nasty and unpredicted (catastrophic and accidental) in your brain (cerebral) to do with your blood vessels or blood supply (vascular).

The Westfield grannies

As a junior doctor working in the north of England many years ago, I along with my colleagues were conscious of the ‘Westfield Grannies’.

Westfield is one of those strange health schemes that pays out money when you are ill. Not enough money to go for private treatment or anything; just a bit of money. One of the ‘triggers’ for payment is admission to hospital - you get a certain amount of cash money for every night you stay on a ward.

Now if you have a chronic illness like emphysema or cardiac disease, you soon learn those magic symptoms that will ensure your admission to hospital. If you have lung disease, just say your exercise tolerance has decreased suddenly. If you have heart disease, say you have got chest pain that won’t go away.

The Westfield Grannies were an informal group of elderly ladies, probably unknown to each other, who would get a few nights in hospital, and then claim their cash. Like Bingo with an overnight stay and antibiotics.

As soon as the Westfield cheque came through, they’d be off to Blackpool or Filey or somewhere for a couple of weeks. All courtesy of their health insurance. And the NHS of course.

These days they probably go to Benidorm to visit their son’s crystal meth lab instead of visiting Filey. But the economics of it are basically the same.

Too poorly

So there’s this bloke. And he is really quite ill. When I asked him why he hadn’t called an ambulance earlier in the course of his disease, like a couple of days ago, his response is that before today he was “too poorly to come to hospital.”

The GMC and value for money

OK, this will probably only be of any appeal to other registered medical practitioners like me who pay £290 a year (£390 from next month) for the privilege of being abused, spat at and vomited on, but have you seen what the GMC (General Medical Council) have just decided to spend some of that money on?

A lucky web designer has just been paid a small fortune to produce an interactive video web tutorial to teach doctors how not to be complete idiots. You can see it here. It’s very pretty and very well done, but as to the content…

In fact that’s the problem with a lot of the GMC’s guidelines. I guess they have to be actually written down somewhere, but if a doctor really needs to be told that it’s best to be polite where possible, honest, not to kill patients or to have sex with them (with or without their informed consent), then that person is probably already heading down the wrong career path.

Saccades are just swell

I’m going to bet you’ve never heard of saccades. Or saccadic movements. They are the jerky movements our eyes make when moving from one object to another. It’s pretty much impossible for most people to move their stare smoothly across the room - our brains naturally jump our eyes from one point of interest to another. Try it now. See? That’s saccades that is. The best way I know of moving your eyes smoothly is to fix on a point and turn your head.

Because your eyes move with incredible speed ( there’s a wikipedia explanation of the arcs and angle and things involved here) when ‘jumping’ from one point to another, you can experience some cool side effects. Some can be experienced when you’re out driving on a motorway. Best done if you are a passenger if you want to avoid crashing. Look at a car in the lane next to you. Now glance forward. Due to ‘persistence of vision’ you will experience, for a split second, a frozen image - in particular you’ll see the car’s wheels appear to have stopped turning. It takes a bit of practice, which is why it’s definitely best not to be driving at the time.

You can notice a similar effect with certain types of lights - do a saccadic jump and you’ll get a ’strobed’ effect trail if the light in question is an LED brakelight, or a 50Hz streetlight. With some of the new xenon headlamps, you can also get a streaked-out spectrum as these lamps emit over a range of light frequencies.

Anyway, that’s saccadic eye movements.
