So you want to be a medical student: READ THIS!

There are so many sources for advice out there for potential medical students. So many books, so many forums, so many careers advice people, and so many confusing and scary myths, that I thought it might be useful to just put up some simple guidelines on what is required to become a medical student and a short book list to get your started. I am now in my 5th year at university and my 4th year of actual medicine. Since getting into Medical School in 2009 I have gone back to my 6th form college in South Wales at least once a year to talk to the students who wanted to become medical or dental students, to offer some advice, answer any queries that I could. This year, I tried to to do the same sort of thing for high achieving pupils at my old comprehensive, because if you don't get the right advice young enough then you won't be able to do everything that is required of you to get into Medical school straight after your A-levels. Unfortunately, due to some new rules I wasn't allowed to. So, since I couldn't give any advice in person I thought that a blog might be the easiest alternative way to give young comprehensive students a guide in the right direction. So here goes... How to get into medical school: You must show that you have the academic capacity to cope with the huge volume of information that will try to teach you and that you have the determination/tenacity to achieve what you need to. To show this you must get good grades: a. >8A*s at GCSE + separate science modules if possible = you have to be able to do science. b. >3A’s at A-Level = Chemistry + Biology + anything else you want, as long as you can get an A. 2. You must have an understanding of what Medicine really involves: a. Work experience with a doctor – local GP, hospital work experience day, family connections, school connections – you should try to get as much as you can but don’t worry if you can’t because you can make up for it in other areas. b. Work experience with any health care professional – ask to see what a nurse/ physio/ health care assistant/ phlebotomist/ ward secretary does. Any exposure to the clinical environment will give you an insight into what happens and gives you something to talk about during personal statements and interviews. c. Caring experience – apply to help out in local care homes, in disabled people’s homes, at charities, look after younger pupils at school. All these sorts of things help to show that you are dedicated, motivated and that you want to help people. 3. Be a fully rounded human being: a. Medical schools do not want robots! They want students who are smart but who are also able to engage with the common man. So hobbies and interests are a good way of showing that you are more than just a learner. b. Playing on sports teams allows you to write about how you have developed as a person and helps you develop essential characteristics like team work, fair play, learning to follow commands, learning to think for yourself, hand-eye co-ordination etc. etc. All valuable for a career in medicine. c. Playing an instrument again shows an ability to learn and the will power to sit and perfect a skill. It also provides you with useful skills that you can use to be sociable and make friends, such as joining student choirs, orchestras and bands or just playing some tunes at a party. d. Do fun things! Medicine is hard work so you need to be able to do something that will help you relax and allow you to blow off some stress. All work and no play, makes a burnt out wreck! 4. Have a basic knowledge of: a. The news, especially the health news – Daily Telegraph health section on a Monday, BBC news etc. b. The career of a doctor – how does it work? How many years of training? What roles would you do? What exams do you need to pass? How many years at medical school? c. The GMC – know about the “Tomorrow’s Doctor” Document – search google. d. The BMA e. The Department of Health and NHS structure – know the basics! GP commissioning bodies, strategic health authorities. f. What the Medical School you are applying to specialises in, does it do lots of cancer research? Does it do dissection? Does it pride itself on the number of GPs it produces? Does it require extra entry exams or what is the interview process? These 4 points are very basic and are just a very rough guide to consider for anyone applying to become a medical student. There are many more things you can do and loads of useful little tips that you will pick up along the way. If anyone has any great tips they would like to share then please do leave them as a comment below! My final thought for this blog is; READ, READ and READ some more. I am sure that the reason I got into medical school was because I had read so many inspiring and thought provoking books, I had something to say in interviews and I had already had ideas planted in my head by the books that I could then bring up for discussion with the interview panel when asked about ethical dilemmas or where medicine is going. Plus reading books about medicine can be so inspiring that they really can push your life in a whole new direction or just give you something to chat about with friends and family. Everyone loves to chat people – how they work, why they are ill, what shapes peoples' personalities etc and these are all a part of medicine that you can read into!

Gin & Tonic Anyone?

It was a Saturday, about tea-time in the quaint village of Athelstaneford, East Lothian. Mrs Alexandria Agutter sat in her cottage, enjoying the delights of the late-summer evening with a glass of gin and tonic. She listlessly sipped from the rather generous pick-me up, no doubt chewing over the happenings of the day. Blast! The taste was much too bitter to her liking. She stood up. And promptly crumpled to the floor in a dizzied heap. It had not been five minutes when a fiery pain gripped her parched throat and in her frenzied turn she watched the bleary room become draped in a gossamery silk. How Dame Agatha would approve. But this is no crime novel, on that fateful day, 24th August 1994, poor Mrs Agutter immortalised herself in the history books of forensic medicine; she was the victim of a revered toxin and a vintage one it was too. She had unwittingly imbibed a G&T laced with a classic poison of antiquity. A clue from the 21st century: do you recall the first Hunger Games film adaption? Those inviting purple-black berries or as Suzanne Collins coined them ‘Nightlock’; a portmanteau of hemlock and Deadly Nightshade. True to the laters’ real life appearance those onscreen fictional fruits played a recurring cameo role. Deadly Nightshade is a perennial shrub of the family Solanaceae and a relative of the humble potato (a member of the Solanus genus). It is a resident of our native woodland and may be found as far afield as Europe, Africa and Western Asia. The 18th century taxonomist, Carl Linnaeus gave the plant an intriguing name in his great Species Plantarum. The genus Atropa is aptly named after one of the three Greek Fates, Atropos. She is portrayed shearing the thread of a mortal’s life so determining the time and manner of its inevitable end. The Italian species name belladona (beautiful woman) refers to the striking mydriatic effect of the plant on the eye. The name pays homage to Pietro Andre Mattioli, a 16th century physician from Sienna, who was allegedly the first to describe the plant’s use among the Venetian glitterati - ladies of fashion favoured the seductive, doe-eyed look. Belladona is poisonous in its entirety. It was from the plant’s roots in 1831, the German apothecary Heinrich F. G. Mein isolated a white, odourless, crystalline powder: it was (surprise, surprise) atropine. Atropine is a chiral molecule. From its natural plant source it exists as a single stereoisomer L-atropine, which also happens to display a chiral potency 50-100 times that of its D-enantiomer. As with many other anaesthetic agents it is administered as a racemic mixture. How strange that atropine now sits among the anaesthetist’s armamentarium, its action as a competitive antimuscarinic to counter vagal stimulation belies its dark history. It was a favourite of Roman housewives seeking retribution against their less than faithful husbands and a staple of the witch’s potion cupboard. Little wonder how belladona became known as the Devil’s plant. Curiouser still it’s also the antidote for other poisons, most notably the organophosphates or nerve gases. On account of its non-selective antagonism, atropine produces a constellation of effects: the inhibition of salivary, lacrimal and sweat glands occurs at low doses; dry mouth and skin are early markers. Pyrexia is a central effect exacerbated by the inability to sweat. Flushing of the face due to skin vessel vasodilatation. Low parasympathetic tone causes a moderate sinus tachycardia. Vision is blurred as the eye becomes dilated, unresponsive to light and accommodation is impaired. Mental disorientation, agitation and ataxia give the impression of drunkedness or a delirium tremens like syndrome. Visual hallucinations, often of butterflies or silk blowing in the wind, are a late feature. It was then that Mr Agutter, seemingly untroubled by the sight of his wife’s problematic situation, proceeded to leave a message with the local practitioner. How fortunate they were to have the vigilant locum check the answering machine and come round to the Agutter’s lodge accompanied by an ambulance crew. The attending paramedic had the presence of mind to pour the remainder of Mrs Agutter’s beverage into a nearby jam jar, while Mr Agutter handed over what he suspected to be the offending ingredient: the bottle of Indian tonic water. As it soon transpired there were seven other casualties in the surrounding countryside of East Lothian – all involving an encounter with tonic water. In fact by some ironic twist of fate, two of the victims were the wife and son of Dr Geoffry Sharwood-Smith, a consultant aneasthetist. Obviously very familiar with the typical toxidrome of anticholinergic agents, he was quick to suspect atropine poisoning. Although for a man of his position with daily access to a sweetshop of drugs, it was not something to draw attention to. Through no small amount of cunning had the poisoner(s) devised the plan. It was elegant; atropine is very bitter. So much so that it can be detected at concentrations of 100 parts per million (0.001%). Those foolish enough to try the berries of belladonna during walks in the woods are often saved by the berry’s sour taste. They are soon spat out. But the quinine in the tonic water was a worthy disguise. The lethal dose for an adult is approximately 90-130mg, however atropine sensitivity is highy variable. In its salt form, atropine sulfate, it is many times more soluble: >100g can be dissolved in 100ml of water. So 1ml may contain roughly tenfold the lethal dose. There ensued a nationwide scare; 50 000 bottles of Safeway branded Indian tonic water were sacrificed. Only six bottles had been contaminated. They had all been purchased, tops unsealed, from the local Safeway in Hunter’s Tryst. Superficially this looked like the handiwork of a psychopath with a certain distaste for the supermarket brand, and amidst the media furore, it did have some verisimilitude: one of the local papers received a letter from 25 year old, Wayne Smith admitting himself as the sole perpetrator. The forensic scientist, Dr Howard Oakley analysed the contents of the bottles. They all contained a non-lethal dose, 11-74mg/litre of atropine except for the Agutter’s, it contained 103mg/litre. The jam jar holding Mrs Agutter’s drink bore even more sinister results, the atropine concentration was 292mg/L. It would appear Mrs Agutter had in some way outstayed her welcome. But she lived. A miscalculation on the part of the person who had added an extra seasoning of atropine to her drink. According to the numbers she would have had to swallow a can’s worth (330ml) to reach the lethal dose. Thankfully she had taken no more than 50mg. The spotlight suddenly fell on Dr Paul Agutter. He was a lecturer of biochemistry at the nearby University of Napier, which housed a research syndicate specialising in toxicology. CCTV footage had revealed his presence at the Safeway in Hunter’s Tryst and there was eye witness evidence of him having placed bottles onto the shelves. Atropine was also detected by the forensic investigators on a cassete case in his car. Within a matter of two weeks he would be arrested for the attempted murder of his wife. Despite the calculated scheme to delay emergency services and to pass the blame onto a non-existent mass poisoner, he had not accomplished the perfect murder. Was there a motive? Allegedly his best laid plans were for the sake of a mistress, a mature student from Napier. He served seven years of a twelve year sentence. Astonishingly, upon his release from Glenochil prison in 2002, he contacted his then former wife proclaiming his innocence and desire to rejoin her in their Scottish home. A proposition she was not very keen on. Dr Agutter was employed by Manchester University as a lecturer of philosophy and medical ethics. He is currently an associate editor of the online journal Theoretical Biology and Medical Modelling. We will never know the true modus operandi as Dr Agutter never confessed to the crime. Perhaps all this story can afford is weak recompense for the brave followers of the Dry January Campaign. Oddly these sort of incidents never appear in their motivational testimonials.

Legal and Ethical Issues in Medical Treatment of Children with Variations of Sex Anatomy

Speaker: Anne Tamar-Mattis An estimated 1 in 2,000 babies is born with a Difference of Sex Development (DSD or intersex condition). Currently, there is much controversy regarding the best course of treatment for those children with DSD born with atypical genitals. However, little attention has gone to the process of decision-making, or to other important questions such as sterilization of children with DSD or protecting privacy rights. This workshop begins with an overview of the biology of DSD and the basic legal and ethical principles of surrogate consent in pediatric cases. We will then discuss some key legal and ethical questions. Participants will become familiar with key legal and ethical issues in the treatment of children with DSDs, with special attention to unsettled questions of law and uncertain medical outcomes. Participants will deepen their understanding of the ethics and law of surrogate decision-making for children. Participants will be able to identify potential situations in the treatment of children with DSDs where additional legal or ethical consultation may be indicated.
