I'd like to tell you a curious story. Jane was a 52 year old woman in need of a kidney transplant. Thankfully she had three loving sons who were all very happy to give her one of theirs. So Jane's doctors performed tests to find out which of the three boys would be the best match, but the results surprised everyone. In the words of Jeremy Kyle, the DNA test showed that Jane was not the mother of two of the boys... Hang on, said Jane, child birth is not something you easily forget. They're definitely mine. And she was right. It turns out Jane was a chimera. Chimerism is the existence of two genetically different cell lines in one organism. This can arise for a number of reasons- it can be iatrogenic, like when someone has an organ transplant, or it can be naturally occurring. In Jane's case, it began in her mum's womb, with two eggs that had been fertilised by different sperm creating two embryos. Ordinarily, they would develop into two non-identical twins. However in Jane's case the two balls of cells fused early in development creating one person with both cell lines. Thus when doctors did the first tissue typing tests on Jane, just by chance they had only sampled the 'yellow' cell line which was responsible for one of her sons. When they went back again they found the 'pink' cell line which had given rise to the other two boys. This particular type of human chimerism is thought to be pretty rare- there are only 30 case reports in the literature. (Though remarkably both House and CSI's Gil Grissom have encountered cases.) What happens far more frequently is fetal microchimerism- which occurs in pregnant women when cells cross the placenta from baby to mum. This is awesome because we used to think the placenta was this barrier which prevented any cells crossing over. Now we've found both cells and free floating DNA cross the placenta, and that the cells can hang around for decades after the baby was born. Why? As is often the case in medicine we're not sure but one theory is that the fetal cells might have healing properties for mum. In pregnant mice who've had a heart attack, fetal cells can travel to the mum's heart where the develop into new heart muscle to repair the damage. Whilst we're still in the early stages of understanding why this happens, we already have a practical application. In the United States today, a pregnant woman can have a blood test which isn't looking for abnormalities in her DNA but in that of her fetus. The DNA test isn't conclusive enough to be used to diagnose genetic conditions, but it is a good screening test for certain trisomies including Down's syndrome. Now, we started with a curious tale, so lets close with a curious fact, and one that's appropriate for Mother's Day: This exchange of cells across the placenta is a two way process. So you may well have some of your mum's cells rushing through your veins right now. In my case they're probably the ones that tell me to put on sensible shoes and put that boy down...

Can you imagine being able to search for locations in the human body in the same way you can on Google Maps? This thinking lead Programmer Rich Stoner to create this amazing video of a 21st Century Map of the Brain which was our most popular tweet last week. A 21st Century Map of the Brain http://t.co/tkojzJBW55 via @brianglanz #openscience— Meducation (@Meducation) October 18, 2013 Rich writes in his blog - “Now we can quickly search Google Maps for a location, ask what is nearby, and even see what it looks like using StreetView. Now, imagine if something like that existed for the human brain: an interactive environment to search, visualize, and explore layers upon layers of neuroanatomy. This is the dream of cortical cartographers (also known as neuroanatomists). 10 years ago, one of the largest brain mapping initiatives was founded by Paul Allen with a single goal: to build a 21st Century Map of the Brain.” Click here to read more. The mapping of the brain is a working progress and therefore not 100% accurate. Even so the video gives us an insight into the innovate ways we will be able to interact with science in the future.

Maybe it’s just me, but I cannot get my head around pharmacology and antibiotics are certainly doing their best to finish me off! My group at uni decided that this was one area that we needed to revise, and the task fell on my hands to provide the material for a revision session. So, the night before the session I began to panic about how to come up with any useful tips for my group, or indeed anyone at all, to try to remember anything useful about antibiotics at all. If only Paracetamoxyfrusebendroneomycin was a real drug, it would make our lives so much easier. Come on Adam Kay and Suman Biswas, get the trials started and create your wonderful super drug. For the mean time I guess I will just have to keep blissfully singing along to your song. However, that is not going to help me with my task in hand. After a lot of research that even took me beyond the realms of Wikipedia (something I do not often like to do), I found various sources suggesting remembering these Top 10 Rules (and their exceptions) All cell wall inhibitors are ?-lactams (except vancomycin) All penicillins are water soluble (nafcillin) All protein synthesis inhibitors are bacteriostatic (aminoglycosides) All cocci are Gram positive (Neisseria spp.) All bacilli are Gram negative (anthrax, tetanus, botulism, diptheria) All spirochetes are Gram negative Tetracyclines and macrolides are used for intracellular bacteria Pregnant women should not take tetracyclines, aminoglycosides, fluroquinolones, or sulfonamides Antibiotics beginning with a ‘C’ are particularly associated with pseudomembranous colitis While the penicillins are the most famous for causing allergies, people may also react to cephalosporins If those work for you, then I guess you can stop reading now… If they don’t, I can’t promise that I have anything better, but give these other tips that I found a whirl… Alternatively, I have created a Page on my own blog called Rang and Dale’s answer to Antibiotics, which summarises their information, so please take a look at that. Most people will suggest that you can categorise antibiotics in three ways, and it’s best to pick one and learn examples of them. Mode of action: bactericidal (kill) bacteriostatic (stop multiplying) 2 mnemonics to potentially help you remember examples: We’re ECSTaTiC about bacteriostatics? Erythromycin Clindamycin Sulphonamides Tetracyclines Trimethoprim Chloramphenicol Very Finely Proficient At Cell Murder (bactericidal) - Vancomycin Fluroquinolones Penicillins Aminoglycosides Cephalosporins Metranidazole Spectrum of activity: broad-spectrum (gram positive AND negative) narrow (gram positive OR negative) Mechanism of action Inhibit cell wall synthesis Inhibit nucleic acid synthesis Inhibit protein synthesis Inhibit cell membrane synthesis If you have any more weird and wonderful ways to remember antibiotics, let me know and I will add them! As always, thank you for reading.

Introduction Hello and welcome! I am finally back to blogging after having a brief hiatus in order to take my final exams. Whilst the trauma is still fresh in my mind, I would like to share with you the top 5 social media tips that helped me through the dark days of undergraduate medicine. Some of you may have already read my old essay on 'How Medical Students should interact with Social Media Networking Sites' and this document deals with some of the problems with professionalism surrounding the use of social media. This blog will not cover such issues, but will instead focus on how you can use social media to benefit your learning/ revision processes. Top Tip 1: YouTube For those of you who are unaware, YouTube is a video-sharing website. Sometimes the site is overlooked as a 'social media' resource but if you consider the simple definition of Social Networking Sites as 'those with user led content,' you can quickly see how YouTube definitely falls into the social media category. It wasn't until I got to University that I realised the potency of YouTube as an educational tool. It has a use at every stage of medical education and it is FREE. If you are still in your pre-clinical training then there are a wealth of videos that depict cellular processes and 3D anatomy - very useful content for the visual learner. For the clinical student, there are a number of OSCE demonstration videos that may be useful in honing your examination skills. There are also a number of presentations on clinical topics that have been uploaded, however, YouTube has no quality control measures for these videos (to my knowledge) so it may be best to subscribe to a more official source if you like to use podcasts/ uploaded presentations for your revision. Another reason YouTube comes in as my number 1 top tip is because I find it difficult to procrastinate whilst using the site. Sure, you can start looking up music and videos that have nothing to do with medicine but personally I find that having a little bit of music on in the background helps me work for longer periods, which is a definite bonus during the revision period. On the other hand, there are many that find YouTube difficult to harness due to the draw of funny videos and favourite Vloggers (Video Bloggers) that can distract the unwary from revision for hours on end. At the end of the day, YouTube was created for funny videos (predominantly of cats it seems) and not for medical education, and this should be kept in mind if you choose to use it as a tool for your learning. Top Tip 2: Facebook Yes, the dreaded Facebook comes in at number two for me. Facebook is by far and away my largest source of procrastination when it comes to writing / working / revising or learning. It is a true devil in disguise, however, there are some very useful features for those who like to work in groups during their revision... For example, during the last six months I have organised a small revision group through Facebook. We set up a 'private page' and each week I would post what topics would be covered in the weeks session. Due to the nature of Facebook, people were obviously able to reply to my posts with suggestions for future topics etc. We were also able to upload photos of useful resources that one or more of us had seen in a tutorial in which the other students hadn't been able to attend. And most importantly, we were able to upload revision notes for each other via the Facebook 'files' tab. This last feature was invaluable for sharing basic notes between a few close colleagues. However, for proper file sharing I strongly recommend the file sharing service 'Dropbox,' which provides free storage for your documents and the ability to access files from any computer or device with internet. Coming back to Facebook, my final thoughts are: if you don't like group work or seeing what your colleagues are doing via their statuses or private messages then it probably isn't a useful resource for you. If you have the motivation (unlike myself) to freeze your Facebook account I can imagine you would end up procrastinating far less (or you'll start procrastinating on something else entirely!). Top Tip 3: Twitter Twitter is a microblogging site. This means that users upload microblogs or 'Tweets' containing useful information they have found on the internet or read in other people's tweets. Twitter's utility as an educational resource is directly related to the 'type' of people you follow. For example, I use Twitter primarily to connect with other people interested in social media, art & medicine and medical education. This means my home screen on twitter is full of people posting about these topics, which I find useful. Alternatively, I could have used my Twitter account to 'follow' all the same friends I 'follow' on Facebook. This would have meant my Twitter home page would have felt like a fast-paced, less detailed version of my Facebook feed just with more hashtags and acronyms - not very useful for finding educational resources. With this in mind, consider setting up two twitter accounts to tease apart the useful tweets about the latest clinical podcast from the useless tweets about what your second cousin once removed just had for lunch. A friend suggested to me that if you really get into twitter it is also possible to use one account and 'group' your followers so that you can see different 'types' of tweets at different times. This seems like a good way to filter the information you are reading, as long as you can figure out how to set up the filters in the first place. Like all Social Media Sites, Twitter gets its fair share of bad press re. online professionalism and its tendency to lure users into hours of procrastination. So again, use with caution. Top Tip 4: Meducation It would not be right to write this blog and not include Meducation in the line-up. Meducation is the first website that I have personally come across where users (students, doctors etc) upload and share information (i.e. the very soul of what social networking is about) that is principally about medicine and nothing else. I'm sure there may be other similar sites out there, but the execution of this site is marvellous and that is what has set it apart from its competitors and lead to its rapid growth (especially over the last two years, whilst i've been aware of the site). When I say 'execution,' I mean the user interface (which is clean and simple), the free resources (giving a taste of the quality of material) and the premium resources (which lecture on a variety of interesting clinical topics rather than sticking to the bread and butter topics 24/7). One of my favourite features of Meducation is the ability to ask 'Questions' to other users. These questions are usually asked by people wishing to improve niche knowledge and so being able to answer a question always feels like a great achievement. Both the questions and answers are mostly always interesting, however the odd question does slip through the net where it appears the person asking the question might have skipped the 'quick google search' phase of working through a tough topic. Meducation harnesses social networking in an environment almost free from professionalism and procrastination issues. Therefore, I cannot critique the site from this angle. Instead, I have decided to highlight the 'Exam Room' feature of the website. The 'Exam Room' lets the user take a 'mock exam' using what I can only assume is a database of questions crafted by the Meducation team themselves (+/- submissions from their user base). However, it is in my opinion that this feature is not up to scratch with the level and volume of questions provided by the competitors in this niche market. I feel wrong making this criticism whilst blogging on Meducation and therefore I will not list or link the competitors I am thinking of here, but they will be available via my unaffiliated blog (Occipital Designs). I hope the Meducation team realise that I make this observation because I feel that with a little work their question database could be improved to the point where it is even better than other sites AND there would also be all the other resources Meducation has to offer. This would make Meducation a truly phenomenal resource. Top Tip 5: Blogging Blogging itself is very useful. Perhaps not necessarily for the learning / revision process but for honing the reflective process. Reflective writing is a large component of undergrad medical education and is disliked by many students for a number of reasons, not least of which is because many find some difficulty in putting their thoughts and feelings on to paper and would much prefer to write with the stiffness and stasis of academic prose. Blogging is great practice for breaking away from essay-writing mode and if you write about something you enjoy you will quickly find you are easily incorporating your own personal thoughts and feelings into your writing (as I have done throughout this blog). This is a very organic form of reflection and I believe it can greatly improve your writing when you come to write those inevitable reflective reports. Conclusion Thanks for reading this blog. I hope I have at least highlighted some yet unharnessed aspects of the sites and resources people already commonly use. Please stay tuned in the next week or two for more on social media in medicine. I am working together with a colleague to produce 'Guidelines for Social Media in Medicine,' in light of the recent material on the subject by the General Medical Council. Please feel free to comment below if you feel you have a Top Tip that I haven't included!

In a recent article in the BMJ the author wonders about the reasons beyond the rising trend diagnosing Attention Deficit Hyperactivity Disorder (ADHD). The article attempts to infer reasons for this. One possible reason was that the diagnostic criteria especially DSM may seem for some to be more inclusive than ICD-10. The speculation may explain the rise of the diagnosis where DSM is used officially or have an influence. In a rather constructive way, an alternative to rushing to diagnosis is offered and discussed in some details. The tentative deduction that the Diagnostic Statistical Manual (DSM) may be one of the causes of rising diagnosis, due to raising the cut-off of age, and widening the inclusion criteria, as opposed to International Classification of Diseases, 10th revision (ICD-10), captured my attention. On reading the ICD-10 diagnostic criteria for research (DCR) and DSM-5 diagnostic criteria, I found them quite similar in most aspects, even the phraseology that starts with 'Often' in many diagnostic criteria, they seem to differ a bit in age. In a way both classification, are attempting to describe the disorder, however, it sounds as if someone is trying to explain a person's behaviour to you, however, this is not a substitute to direct clinical learning, and observing the behaviour, as if the missing sentence is 'when you see the person, it will be clearer'. El-Islam agrees with the notion that DSM-5 seems to be a bit more inclusive than ICD-10. A colleague of mine who is a child psychiatrist and she is doing her MSc. thesis in ADHD told me, that DSM-5 seems to be a substantial improvement as compared to its predecessor. The criteria - to her - though apparently are more inclusive, they are more descriptive with many examples, and she infers that this will payback in the reliability of the diagnosis. She hopes gene research can yield in biological tests for implicated genes and neurotransmitters in ADHD e.g. DRD4, DAT, gene 5,6,11 etc. One child psychiatrist, regretted the fact that misdiagnosis and under-diagnoses, deprive the patient from one of the most effective treatments in psychiatry. It is hoped the nearest forthcoming diagnostic classification (ICD-11), will address the issue of the diagnosis from a different perspective, or else converge with DSM-5 to provide coherence and a generalised newer standard of practice. The grading of ADHD into mild, moderate, and severe seem to blur the border between disorder and non-disorder, however, this quasi-dimensional approach seems realistic, it does not translate yet directly in differences in treatment approaches as with the case of mild, moderate, severe, and severe depression with psychotic symptoms, or intellectual disability. The author states that one counter argument could be that child psychiatrists are better at diagnosing the disorder. I wonder if this is a reflection of a rising trend of a disorder. If ADHD is compared to catatonia, it is generally agreed that catatonia is less diagnosed now, may be the epidemiology of ADHD is not artefact, and that we may need to look beyond the diagnosis to learn for example from environmental factors. Another issue is that there seems to be significant epidemiological differences in the rates of diagnosis across cultures. This may give rise to whether ADHD can be classified as a culture-bound syndrome, or whether it is influenced by culture like anorexia nervosa, or it may be just because of the raising awareness to such disorders. Historically, it is difficult to attempt to pinpoint what would be the closest predecessor to ADHD. For schizophrenia and mania, older terms may have included insanity, for depression it was probably melancholia, there are other terms that still reside in contemporary culture e.g. hypochondriasis, hysteria, paranoia etc. Though, it would be too simplistic to believe that what is meant by these terms was exactly what ancient cultures meant by them, but, they are not too far. ADHD seems to lack such historical underpinning. Crichton described a disorder he refers to as 'mental restlessness'. Still who is most often credited with the first description of ADHD, in his 1902 address to the Royal College of Physicians. Still describes a number of patients with problems in self-regulation or, as he then termed it, 'moral control' (De Zeeuw et al, 2011). The costs and the risks related to over-diagnosis, ring a warning bell, to enhance scrutiny in the diagnosis, due to subsequent stigma, costs, and lowered societal expectations. They all seem to stem from the consequences of the methodology of diagnosis. The article touches in an important part in the psychiatric diagnosis, and classifications, which is the subjective nature of disorders. The enormous effort done in DSM-5 & ICD-10 reflect the best available evidence, but in order to eliminate the subjective nature of illness, a biological test seems to be the only definitive answer, to ADHD in particular and psychiatry in general. Given that ADHD is an illness and that it is a homogeneous thing; developments in gene studies would seem to hold the key to understanding our current status of diagnosis. The suggested approach for using psychosocial interventions and then administering treatment after making sure that it is a must, seems quite reasonable. El-Islam, agrees that in ADHD caution prior to giving treatment is a recommended course of action. Another consultant child psychiatrist mentioned that one hour might not be enough to reach a comfortable diagnosis of ADHD. It may take up to 90 minutes, to become confident in a clinical diagnosis, in addition to commonly used rating scales. Though on the other hand, families and carers may hypothetically raise the issue of time urgency due to scholastic pressure. In a discussion with Dr Hend Badawy, a colleague child psychiatrist; she stated the following with regards to her own experience, and her opinion about the article. The following is written with her consent. 'ADHD is a clinically based diagnosis that has three core symptoms, inattention, hyperactivity and impulsivity in - at least - two settings. The risk of over-diagnosis in ADHD is one of the potentially problematic, however, the risk of over-diagnosis is not confined to ADHD, it can be present in other psychiatric diagnoses, as they rely on subjective experience of the patient and doctor's interviewing skills. In ADHD in particular the risk of under-diagnosis is even more problematic. An undiagnosed child who has ADHD may suffer various complications as moral stigma of 'lack of conduct' due to impuslivity and hyperactivity, poor scholastic achievement, potential alienation, ostracization and even exclusion by peer due to perceived 'difference', consequent feelings of low self esteem and potential revengeful attitude on the side of the child. An end result, would be development of substance use disorders, or involvement in dissocial behaviours. The answer to the problem of over-diagnosis/under-diagnosis can be helped by an initial step of raising public awareness of people about ADHD, including campaigns to families, carers, teachers and general practitioners. These campaigns would help people identify children with possible ADHD. The only risk is that child psychiatrists may be met with children who their parents believe they might have the disorder while they do not. In a way, raising awareness can serve as a sensitive laboratory investigation. The next step is that the child psychiatrist should scrutinise children carefully. The risk of over-diagnosis can be limited via routine using of checklists, to make sure that the practice is standardised and that every child was diagnosed properly according to the diagnostic criteria. The use of proper scales as Strengths and Difficulties Questionnaire (SDQ) in its two forms (for parents SDQ-P and for teachers SDQ-T) which enables the assessor to learn about the behaviour of the child in two different settings. Conner's scale can help give better understanding of the magnitude of the problem. Though some people may voice criticism as they are mainly filled out by parents and teachers, they are the best tools available at hands. Training on diagnosis, regular auditing and restricting doctors to a standard practice of ensuring that the child and carer have been interviewed thoroughly can help minimise the risk of over-diagnosis. The issue does not stop by diagnosis, follow-up can give a clue whether the child is improving on the management plan or not. The effects and side effects of treatments as methylphenidate should be monitored regularly, including regular measurement height and weight, paying attention to nausea, poor appetite, and even the rare side effects which are usually missed. More restrictions and supervision on the medication may have an indirect effect on enhancing the diagnostic assessment. To summarise, the public advocacy does not increase the risk of over-diagnosis, as asking about suicidal ideas does not increase its risk. The awareness may help people learn more and empower them and will lead to more acceptance of the diagnosed child in the community. Even the potential risk of having more case loads for doctors to assess for ADHD may help give more exposure of cases, and reaching more meaningful epidemiological finding. From my experience, it is quite unlikely to have marked over-representation of children who the families suspect ADHD without sufficient evidence. ADHD remains a clinical diagnosis, and it is unlikely that it will be replaced by a biological marker or an imaging test in the near future. After all, even if there will be objective diagnostic tests, without clinical diagnostic interviewing their value will be doubtful. It is ironic that the two most effective treatments in psychiatry methylphenidate and Electroconvulsive Therapy (ECT) are the two most controversial treatments. May be because both were used prior to having a full understanding of their mechanism of action, may be because, on the outset both seem unusual, electricity through the head, and a stimulant for hyperactive children.

What is Problem Based Learning? During my time at medical school, I enjoyed (at times) a curriculum delivered through the traditional model. As the name suggests, this is an approach experienced by the majority of doctors to date. The traditional model was first implemented by the American Medical College Association and American Academy of Medicine in 1894 (Barr, 2010) and has been used by the majority of medical schools. It traditionally consists of didactic lectures in the initial years covering the basic sciences followed by clinical years, where students learn clinical medicine while attending hospital placements. Is It Better? A few years after my graduation I found myself teaching at a university which had fully adopted the use of problem based learning (PBL) in the delivery of their curriculum. PBL is a philosophy of teaching that has increasingly been used in medical education over the past 40 years. It has rapidly been replaced or supplemented in medical education as opposed to the traditional model. PBL seeks to promote a more integrated and active approach to learning right from the first year with less reliance on didactic lectures. Having been involved in these two different approaches to medical education, I was interested to explore what the evidence was for and against each. For the purposes of this blog, I have looked at four specific areas. These include student attitudes, academic achievement, the academic process of learning and clinical functioning and skills. Student Attitudes Student attitudes to PBL have been highly featured in studies and many show that there is a clear favourability towards this philosophy of teaching. Blumberg and Eckenfel (1988) found that students in a problem based preclinical curriculum rated this three times higher than those in the a traditional group in terms of what they expect to experience, what they would like, and what they actually experienced. Heale et al (1988) found physicians in the problem-solving sessions rated a Continuing Medical Education short course higher compared to others who attended traditional lectures and large-group sessions. Vernon and Black (1993) performed a Meta analysis on 12 studies that looked at attitudes and towards PBL and found PBL was favored in some way by all studies. PBL appears to be preferred by the majority of students at a range of academic levels. However, Trappler (2006) found that converting a conventional curriculum to a problem based learning model for part of a psychopathology course did not show complete favourability. Students preferred the conventional lectures given by experts, rather than PBL groups run by mentors and not experts. They did however show preference towards PBL small group sessions run by experts Academic Achievement Academic achievement is an important factor to assess. Vernon and Blake (1993) compared a number of studies and found that those, which could be compared, showed a significant trend favouring traditional teaching methods. However, it was felt this might not be reliable. When looking at the heterogeneity of the studies there was significant variation that could not be accounted for by chance alone. Interestingly, they found that there was significant geographical variation across the United States such that New Mexico showed consistently negative effects and Michigan State showed consistently positive. Other studies have shown that the traditional method may show a slightly better outcome when assessing academic achievement. Schmidt et al (1987) looked at the same progress test taken among students in six different Universities in the Netherlands and found that those taught by a traditional approach showed slightly better outcomes. Baca et al (1990) compared performances of medical students in two separate tracks, one PBL the other a traditional model. Baca et al found that PBL students scored slightly lower in the National Board of Medical Examiners (NBME) examinations. Dochy et al (2003) conducted a meta analysis comparing 43 studies and found that when considering the effect of PBL on the knowledge of students the combined effect size is slightly negative. The academic process of learning It is important in medical education to enable people to continue life long learning, to overcome problems and fill in knowledge gaps. Coles (1990) and Entwistle (1983) found that PBL students would place more emphasis on understanding and meaning compared to just rote learning, seen more in those taught by a traditional approach. Students on a PBL course also place more focus on using resources such as the library and online sources rather than those taught in a traditional approach (Rankin, 1992). Students taught by a traditional model place more emphasis on the resources supplied by the faculty itself. It has also been shown that students who learn through a process of problem solving, are more likely to use this spontaneously to solve new problems in the future compared with those taught in a traditional way (Bransford et al, 1989). Clinical functioning and skills Clinical competence is an important aspect in medical education and has been measured in studies comparing PBL and traditional methods. The traditional model focuses acquisition of clinical competence in the final years of a program with hospital placements. In a PBL course it may be more integrated early on. There are however, only a few studies that look at clinical competence gained in undergraduate PBL courses. Vernon and Blake (1993) compared some of these studies and found that students obtained better clinical functioning in a PBL setting compared to a traditional approach. This was statistically significant, however there was still significant heterogeneity amongst studies and for conclusive results to be made 110 studies would have to be compared, rather that the 16 samples they were able to use. They also found that in contrast to the NBME I giving better results in the traditional model, PBL students score slightly higher in NBME II and federation licensing examination which related more on clinical functioning than basic sciences. On reflection, this evidence has indicated to me that PBL is a very valuable approach and it has a number of benefits. The traditional model in which I was taught has provided a good level of academic education. However, it may not have supported me as well as a PBL course in other areas of medical education such as academic process, clinical functioning and satisfaction. On reflection and current recommendations are for a hybridisation of the PBL and traditional approach to be used (Albanese, 2010) and I would support this view in light of the evidence.

So, I think its about time I posted another blog post! A few weeks ago I received the results from my most recent scan. I was both nervous and excited to find out my results, after months of tests and being misdiagnosed several times I just wanted to know what was wrong with me. However, as I read through the letter from my consultant I realised that my journey was just beginning. I was diagnosed with a rare stomach condition. Gastroparesis. A chronic illness. There is no known cure, just various treatments with limited success. I didn’t really know how to react to this news. Shouldn’t I be happy that I finally knew what was wrong? I had convinced myself for months that as soon as the doctors found out what was wrong, they could fix it and I’d be better in no time, but this wasn’t to be. I couldn’t understand how this could happen. Slowly the reality began to sink in, I’ll probably be fighting this battle for the rest of my life. I think the mental aspect of chronic conditions is so commonly overlooked. I’ve sat through endless lectures about the pathophysiology of illnesses but I’ve never once stopped to think what it must be like to actually have it. The way it can limit your life, from not being able to go for a drink with friends because you’re in too much pain to the countless hospital appointments that your life seems to revolve around. The thing that hit me the most is the amount of medications I have to take on a daily basis just to make my symptoms bearable. I no longer have full control of my life and that's the worst part. This experience has given me an invaluable insight into how patients with chronic illness feel. It affects almost every aspect of your life and you can never escape. It scares me to think of the future, I never know when I’m going to get my next flare up or how long its going to last. I just have to take one day at a time and hope that when I wake up tomorrow I won’t be too nauseous. After spending a few weeks feeling down about it all, I’ve realised that I just have to enjoy life when I can and be grateful that I can still live a normal-ish life. It doesn’t matter how much I complain, it's not going to go away, and I think I’ve finally accepted that fact. If anything, this experience has made me more determined to achieve my dream of becoming a doctor. I’ve been a lot more motivated to work harder so that one day I can help others like me through some of their toughest times, hopefully bringing them some comfort and relief.

I’m sure there are times when all us GPs feel under-appreciated — by our patients, staff, specialist colleagues or society in general. You can’t blame them for sometimes taking us for granted — it’s part of the human condition. People don’t value what they have until they lose it, whether “it” is the ability to walk or a domestic fairy who makes sure there’s always spare toilet paper. It’s a common lament that we can’t be at our own funerals to hear how much we’re loved. Mind you, eulogies are rarely objective and balanced. Nonetheless, it’s a pity we’re not around to hear the praise — deserved or otherwise — that is expressed once we’re gone. The long-serving, somewhat-taken-for-granted GP has a non-fatal way of bringing out the appreciation in his or her patients and staff: moving on. After 10 years of GP-ing in the Noosa hinterland and a lifetime of living in south-east Queensland, I headed south of the border: to northern NSW. The hardest part of the move for me — harder than selling my house in a depressed market, harder than dealing with banks, builders, real estate agents, solicitors and Australia Post, harder even than trying to get rational answers out of my telecommunications company after they cut off my internet and phone prematurely — was telling my patients that I was leaving. I knew many of my patients were very attached. I knew they’d come to me expecting to receive a loyal, life-long partner kind of doctoring, rather than the one-night-stand variety. But I had no idea how difficult it would be to break the “I’m leaving you” news again and again and again. Hard as breaking up a relationship may be, at least you only have to do it once when you leave a romantic partnership. For me, telling patients I was leaving felt a bit like breaking up with hundreds of boyfriends, one after the other after the other. You may interpret this as my being too close to my patients or not close enough to my boyfriends, but the fact is I found the protracted process exhausting, emotionally draining and just plain horrible. The “it’s not you, it’s me” part goes without saying and I know I am far from irreplaceable, but seeing the tears well up in countless eyes because of the words I’ve uttered was enough to break my tender heart. Looking on the bright side, as I am wont to do, if I’d ever felt under-appreciated, I sure don’t now. I received more expressions of gratitude in those last three months than I did in the previous decade. To hear how influential I was in some of my patients’ lives put a warm glow in my battered heart. And as much as it hurt me to see my patients upset, it probably would’ve hurt me more if they’d been completely indifferent to my leaving. However, I did please someone. Mrs L had been trying for years to get her husband to agree to move interstate to be near family. His last remaining excuse was that his multiple complex medical problems meant that he couldn’t possibly leave me, his long-term GP. A grateful Mrs L rang me within hours of my informing them of my impending departure to say: “He’s finally come around. Thank you so much for deciding to leave us.” It’s nice to be appreciated!
