Paediatric metabolic biochemistry is a rapidlydeveloping sub-specialty. Important new services fornewborn screening (haemoglobinopathies, cysticfibrosis, medium chain acyl CoA dehydrogenasedeficiency, plus the potential for other metabolicdisorders) are creating increased demands for clinicalscientists for the future. In addition there is thecontinued expansion of inherited metabolic disordersand the need for the specialist laboratory to supportdiagnosis and management of patients with thesecomplex disorders. An added pressure to the demandsfor new posts is the impending retirement of severalsenior members!

In order to address these important issues, theDepartment of Health, as part of the Genetics WhitePaper, has funded a training strategy for metabolicbiochemistry; this includes the funding of trainersacross England and eight higher specialist trainee posts.These latter posts will be 5-year supernumerary postsfor Grade B Clinical Scientists who wish to train in thisspecialist area. Post-holders will be expected tocomplete training for their MRCPath and will be givensupport to attend appropriate courses/meetings,including specialist meetings, e.g. British InheritedMetabolic Disease Group, Society for the Study ofInborn Errors of Metabolism.

Dr Mick Henderson has been appointed as LeadTrainer for the Network and, subsequently, it is plannedthat trainers will be appointed across clusters in threecentres (the North – Sheffield, the Midlands –Birmingham and the South – London). Together thesewill form a co-ordinated approach to training to

support these new HST posts, and also to strengthen thecore training for paediatric biochemistry for Grade Atrainees across England. For the latter it is hoped thatthere will be some standardization of secondments andtraining programmes as a means of rectifying some ofthe deficiencies which have been identified by theTraining Committee.

These developments are clearly very exciting and theNetwork is delighted that the Department of Health hasfunded these initiatives. The timescale is for theappointment of the trainer posts within the next threemonths. All these trainer initiatives should be in placefor the appointment of the HST posts from October2004 onwards.

The HST posts are advertised in this month’s ACBNews. There are posts in the following centres:Birmingham Children’s Hospital; BristolSouthmead/Bristol Royal Infirmary; AddenbrookesHospital, Cambridge; Liverpool Children’s Hospital(Alder Hey); Great Ormond Street and Guy’s & StThomas’s, London; Manchester Children’s Hospital andSheffield Children’s Hospital

Candidates will be expected to state their preferencefor centres in priority order. If you are interested infinding out more, please do not hesitate to contact Dr Anne Green, Lead Scientist, Clinical ChemistryDepartment, Birmingham Children’s Hospital.Tel: 0121-333-9922.

The Trace Element andMicronutrient Unit atGlasgow Royal InfirmaryBy Dr David Halls, Glasgow Royal Infirmary

http://www.trace-elements.org.uk

Whilst this site was originally intended primarily as a handbook for users ofthe service of this Scottish Reference Laboratory, it has much tocommend it as a source of information to any biochemist wishing to find

out more about the essential trace elements, toxic elements and vitamins. Traineebiochemists will find an introductory tutorial on trace elements, written originallyby Professor Gordon Fell, one of the pioneers of trace element clinical research inthe UK. Pages on trace elements from aluminium to zinc and vitamins from A to Egive details of the biochemistry of that element, the relevance of possiblemeasurements as well as sample requirements and reference ranges. Many pagesgive links to other sites to help further research. For those involved in occupationalmonitoring, an explanation is given of the “Control of Lead at Work Regulations.2002” as they apply to biological monitoring and a converter allows conversion ofblood lead results in µmol/L to those old-fashioned µg/100 mL units that theRegulations cling to.

• Don’t forget, links to all past and present ‘Websites of the Month’ are availablefrom the ACB website (www.acb.org.uk). If you wish to suggest a site for the‘Website of the Month’, please submit a short review (150-200 words) to IanGodber at Wishaw General Hospital ([email protected]). ■

Deacon’s ChallengeNo. 40 AnswerThe SHO in ITU carried out a blood gas analysis but failed to record all of the results in the patient’s notes.The only available results are:

H+ concentration = 93 nmol/LStandard bicarbonate = 15 mmol/LActual bicarbonate = 21 mmol/L

Calculate the pH and Pco2 (in kPa). Assume the solubility coefficient of CO2 (in kPa) is 0.225.

pH = - log10 [H+]

To convert the H+ concentration from nmol/L to mol/L divide by 1,000,000,000.

[H+] = 93 = 0.000 000 093 mol/L1,000,000,000

pH = - ( log10 0.000 000 093 ) = - (-7.03) = 7.03

The Henderson-Hasselbalch equation for the bicarbonate – CO2 pair is:

pH = pKa + log10 [HCO3–]

α Pco2

substitute:pH = 7.03

pKa = 6.1[HCO3

–] = actual bicarbonate = 21 mmol/L

α = solubility coefficient for CO2 in water = 0.225

then solve for Pco2

Focus Workshops Focus Workshops Focus Workshops Focus

This popular workshop led by Professor Furness, aHistopathologist from Leicester, centred on discussion ofthe Human Tissue Bill currently going through

Parliament. Within the Bill, ‘tissue’ is defined as any materialcontaining human cells. All biochemical samples (i.e. blood,urine, faeces, fluids) are thus included.

Under the new Bill, it will become illegal to use any suchsample for research or training, which is not ‘incidental to thediagnostic process’ and without ‘appropriate’ patient consent.No distinction is made between different grades of researchactivity (ie developing a new method versus a full-scale clinicaltrial) and use for training is poorly defined. Consent must beexplicit - although there are no plans/resources for achievingthis. No distinction is made between tissue (samples) surplus todiagnostic requirements (i.e. waste) and that required as part ofthe patient clinical record (i.e. retained). Use of anonymisedsurplus samples for research projects would therefore becomeillegal. The position on laboratory addition of tests that werenot requested is also unclear.

The penalties for breaking the law would be significant finesor up to 3 years imprisonment. Enforcement would become theresponsibility of a (new) Human Tissue Authority, but it isuncertain whether there would be pathologist representationwithin this body.

In conclusion, Professor Furness stated that, although writtenprimarily in response to recent organ retention scandals involving post-mortem specimens, the proposed legislation willbe applicable to all human tissue specimens and is thereforerelevant to all pathology disciplines. He explained that there aremany anomalies within the Bill and areas that raise concern forcurrently accepted laboratory activity. He urged all ClinicalBiochemists to familiarise themselves with the contents of theBill and encouraged further discussion with local pathologystaff, Chief Executives, MPs and the DoH as a matter of urgency.

At the outset thanks were given to the manufacturers of systems formeasurement of glycated haemoglobin, all of whom provided information forthe workshop on how results from their systems should be reported in the

presence of haemoglobin variants.Miss Janet Smith and Dr Sue Manley (Birmingham) reminded us of the current UK

guidelines for treatment of diabetes and the importance of providing accurate HbA1cresults. The treatment goals set by NICE (National Institute for Clinical Excellence) fortype 2 diabetes are HbA1c (DCCT aligned) between 6.5-7.5% for an individualpatient, depending on their risk of complications or hypoglycaemia. Measurement ofHbA1c is recommended at 2-6 monthly intervals. The new GP contract providesmaximum points (and therefore funding) if HbA1c levels are maintained below 7.5%in diabetic patients.

The validity of HbA1c results in the presence of haemoglobin variants wasdiscussed. Although some methods allow the measurement of HbA1c whenparticular variants are present, the results do not necessarily relate to DCCT values.Glycation rates may differ in the presence of variants, consequently the relationshipbetween plasma glucose concentration and HbA1c will be different in these patients.HbA1c in patients with variants should therefore not be used when treating todefined goals.

Alternative Approaches in Presence of VariantsFor patients with haemoglobinopathies it is important to determine whether HbA1ccan be reported from the particular method employed. We gave the approach of ourown laboratories to reporting HbA1c in the presence of haemoglobin variants. It isrecommended that if HPLC is employed, chromatograms must always be reviewed tolook for variants. If HbA1c cannot be reported due to the presence of a variant whichleads to a falsely elevated or decreased result for HbA1c, an alternate method formeasurement of HbA1c or glycaemic control should be employed. Most laboratoriesusing HPLC routinely use affinity chromatography, immunoassay or fructosamine asalternate methods.

We reviewed HPLC chromatograms to look for variants and some interestingexamples of interferences in HbA1c methods were presented, including the case of afalsely elevated HbA1c value obtained from a POCT system due to the presence ofpersistent HbF. This highlighted the importance of educating users in the limitationsof HbA1c POCT systems, particularly with the expanding use of these systems inPrimary Care.

Delegates were all provided with the contents of this workshop in the form of a CD,together with some recently published papers on the subject. ■

Several weeks before this meeting, participants received a series of cases from Dr ChrisFlorkowski (New Zealand) around which the workshop was structured.

Case 1

34 year old female presents acutely psychotic. Free thyroxine index (FTI) 220 (55-160), TSH 20.4mU/L (0.4-4 mU/L).This case illustrated interference: TSH was suppressed using an alternative assay.Strategies for investigating interference were discussed and it was felt that an expedient approach wasto use an alternative assay. Binding protein abnormalities were discussed, but the use of free hormoneassays largely overcomes such problems in these cases.

Case 2

84 year old male. No clinical details. Total T4<10 nmol/L (55-140 nmol/L), FTI 9 (55-160), TotalT3 4.14 nmol/L (1.2-2.8 nmol/L), TSH 2.82 mU/L. A confusing set of results, but the interpretationis simple given that patient is taking T3. The lesson being to have all the relevant information to hand.

Case 3

31 year old male, presenting thyrotoxic. Raised Total T4 166 nmol/L and FTI 382 with a raised TSHof 8.8 mU/L. Imaging studies revealed a pituitary adenoma (TSH-oma). A TRH test was performed,which gave a flat response as would be expected in this situation. The value of measuring alphasubunits in such cases was mentioned.

Case 4

Generalised resistance to thyroid hormone (GRTH). In such cases T4 and T3 are elevated with anormal or increased TSH. Family studies are important, and some genetic testing is available. There isa dominant inheritance pattern and prevalence is approximately 1:50,000. Clinically, expression isvariable and patients can be asymptomatic. An important consideration when faced with such resultsis distinguishing from a TSH-oma.

Case 5

This involved a baby born to a thyrotoxic mother (thyroid stimulating antibodies) who throughoutpregnancy was treated with propylthiouracil (PTU). TFTs on the cord blood indicatedhypothyroidism – a transient effect due to trans-placental PTU. The infant then became transientlythyrotoxic, due to the persistence of maternal antibodies. Despite biochemical abnormalitiestreatment was appropriately withheld.

Apparent resistance to thyroxine and carbimazole was discussed. Possible causes of a persistenthyperthyroid state despite treatment with carbimazole were ectopic thyroid tissue or factitioushyperthyroxinaemia.

Other topics included the effects of amiodarone, and non-thyroidal illness (NTI). Data were showndemonstrating that total T4 was most likely to fall within the euthyroid range in patients with NTI. ■

This was a well attended workshop, held on a narrowboat on asunny Wednesday morning. Dr Steve George from the RegionalToxicology Laboratory, in Birmingham wasted no time and we set

sail for a whirlwind tour.The use of saliva was discussed. Benefits included watching the

sample being taken, but many disadvantages were also highlighted suchas the issue of residual effects, needing assays specific for the parentdrug rather than metabolites and low concentrations of drug (all withcost implications). Sweat analysis is falling out of favour due to thepotential of adulteration of the collection patches and hair analysis wasdeemed to be unsatisfactory due to external contamination, difficultextraction procedures and, again, low concentrations. This brought usback to the use of blood and urine for routine DOA investigations withnew techniques such as GC/MS and LC/MS/MS to combat cross-reactivity issues.

The potential of POCT devices for DOA screening is well recognised,but the same issues of quality control, operator training andunderstanding of assay limitations such as sensitivity and specificitywere again raised. This is especially relevant considering their useoutside the hospital setting at job interviews and schools etc. ManyPOCT users were reported to have little interest in quality assurance andthe question was raised as to whether the MHRA should impose QCprocedures and education and pressurise manufacturers to support thecosts.

As the narrowboat was pulling into dock, medico-legal issues werediscussed, with the awareness that more litigation was arising fromDOA screening. We were reminded of the importance of keeping welldocumented files for up to 2 years, which in itself brings up the furtherissue of space in our already cramped laboratories. Finally, theimportance of chain of custody was stressed. ■

The lunchtime sessions held at Focus 2004 were a valuable opportunity for delegatesto meet with officers from the Federation of Clinical Scientists; Geoff Lester, AlanPenny and Tim Saben (local representative at Guy’s and St Thomas’). The aim was to

provide an up to date briefing on progress with Agenda for Change and to answer as manyquestions as possible in the limited time frame.

It was standing room only at the Tuesday session I attended – reflecting the high level ofinterest from Focus delegates. The principles of the NHS Job Evaluation Scheme werereviewed and the process by which existing posts will be matched to the 8 bands of thenew system. The early implementer sites have not yet reported, but some general pointsabout the process are becoming evident. The FCS opinion was that the amount of time andresources required by each Trust should not be underestimated. Trusts will be askingpeople to form working parties within each organisation, some Trusts have asked for vol-unteers, others have asked that each department allocate a given number of staff to theproject. However the team is formed, it is not expected that staff from a given departmentwould be involved in job matching colleagues within the same department. Each SHA hasan AFC Lead and they would be the initial contact for people keen to be involved in theprocess at a local level.

The FCS Officers were keen to emphasise the practical aspects of undertaking the jobmatching process. In particular their recommendation was that the job matching teamshould be allocated dedicated office space during the process. This would enable allrelevant documents to be readily accessible with quiet space available for private consulta-tion with staff members etc. Ready access to a range of documents is likely to be requiredduring the job matching process – easy availability of telephones, a PC and internet accesscan all help to make the process run as smoothly as possible.

Many questions were asked by delegates, below are a summary of the main subjects covered. More details can be found on the FCS websitehttp://www.acb.org.uk/federation

Job BandingsThe evidence for your current role should be presented in the job description and a scoreassigned for each of the 16 factors outlined in the NHS Job Evaluation scheme profiles.This is then matched to a ‘job family’ - it is expected that clinical scientists would bematched against other scientific disciplines (rather than allied health professionals, forexample). It was stressed that jobs which exist now do not map directly to the new bands,nor do titles define a role. It is recognised that the profession is effectively being com-pressed from the current system - due to the nature of the profession Grade As shouldstart at no lower than band 5. However, the new system could lead to significant opportu-nities for certain areas for the profession, in particular high grade Bs who are currentlydoing the work of a Grade C. The job matching process provides an opportunity for thisrole to be recognised and matched to the job evaluation scheme accordingly.

At present there is not a full set of published job profiles to cover the whole range ofpost-registration clinical scientists, up to and including clinical director level. This is being

addressed and members are advised to watch the FCS website closely for further information.

Generic person specifications for different grades are being developed and these shouldbe used by Heads of Departments to inform the job matching process. Again it was emphasised that skills are matched to the job, not the person. If a person has PhD, forexample, but is employed in a post where a PhD is not required, then this cannot be takeninto account for grading purposes.

Those who haven’t yet seen a copy of the 71 page FCS Guidance on job descriptions areadvised to visit their web site where a pdf file can be downloaded or viewed electronically(to save trees!). There are also a number of informative Q&A articles which aim to addressspecific questions of members.

Essential information which the job matching panel will need includes:• person specification – details skills required• job description – outlines roles and responsibilities• organisational chart – outlines accountabilities and line management• supplementary documentation – details conditions of work etc.

What is the Timescale for Implementation?Foundation Hospitals wanted to implement AFC in October, but currently there is not fullunion agreement to the proposals. Early implementers have had the go-ahead to start thepilot but the process is unlikely to get underway before December 2004.

Specialist PostsThe generic person specifications will not cover specialist areas such as paediatrics. Specificroles and responsibilities for those positions will need to be added to the appropriateperson specification.

What about Clinical Scientists who also hold

posts as Clinical Directors?Issues around the role of Clinical Director still need to be resolved. Many unions want tosee introduction of a band 9 although the Department of Health is strongly resistant to this.Roles which are graded as 8D or above will need to be referred for evaluation.

Out of Hours WorkingThe position on this is clearly stated in the agreement. It is likely to be more of an issue forBMS colleagues. The AFC is essentially a drive towards a flatter, 24/7 form of servicedelivery. Other professions such as radiographers also have similar concerns.

In conclusion, the Agenda for Change seems to have been the subject of much discussionfor several years. We are now entering the ‘action’ phase of the process, where things arelikely to progress much more rapidly, particularly as the early implementer sites make theirreports public. ■

The scientific session, chaired by Dr Damian Griffin, took thetheme of the assessment of cardiac risk factors. It openedwith Dr Nuha Haboubi of the West Wales General Hospital

updating the audience on developments in lipid management.Nuha concentrated on new therapies such as ezetimibe and newformulations of more established products, particularly nicotinicacid.

Dr Lena Izzat, an Associate Specialist in Cardiology at the PrincePhilip Hospital, continued with an overview of the assessment ofrisk in a Chest Pain Assessment Clinic and emphasised the use ofPOCT assays of troponin in this environment. Although thenumber of occasions where a POCT troponin was actually used wascomparatively small, she emphasised the clinical usefulness, evenin this small number of cases where the wait for a laboratory assaywould not have been practical.

After coffee, Dr Mike Penney gave a brief review of thephysiology and clinical utility of natriuretic peptides and thenfocussed on the potential cost to laboratories of implementing thetest according to NSF guidelines. At current market rates, the costof introducing BNP into his repertoire could cost his department inexcess of £1 million per year. Dr Penney compared the cost ofscreening patients with BNP to reduce the number of referrals forechocardiography and concluded that the cost of BNP assays mustcome down considerably to make this cost effective.

Dr Paul Collinson managed to negotiate the rail networksuccessfully and delivered a talk on ischaemia modified albumin,presenting data so new that it had not yet been reported elsewhere.Dr Collinson outlined the current theory of disordered cobaltbinding to the N-terminal of human serum albumin and itspotential use as an intermediary marker in the assessment ofcardiac risk.

Wales AuditFollowing straight on from the scientific meeting, the All WalesClinical Biochemistry Audit Group held their meeting. Chairman,Dr Keith Griffiths of Bangor presented an overview of the activitiesof the group emphasising its multidisciplinary constitution. Thegroup has currently audited practice within Wales of 18 or so areasof activity within clinical biochemistry and these reports can befound at HYPERLINK http://www.acb.org/welshauditwww.acb.org/welshaudit.

which handles some 1800 requestsevery day, seized the opportunity andinvited Olympus to conduct a full‘process management’ study. The evaluation identified sample handling as an area where major benefits would be gained by improved efficiency.

Typical of most pathology labs throughout the country, manual sortingof samples and transfer to the appropriate analyser or storage areaare tasks requiring valuable time.Inevitably, each is open to a degree ofhuman error, estimated at between 1and 3%. Since the installation of anOlympus OLA 2500, PeterThompson,General Manager of the lab commented,“The new Olympus systems have gone

a long way to solving the problem.”

The system provides automated sample handling, both pre and postanalytical, with minimum hands-ontime. The high throughput bringsconsiderable savings in terms of bothtime and money to the typical path lab.“Where samples were previously sortedmanually, automated handling frees uphighly trained personnel for moreimportant tasks. Pressure is eased onboth the lab and the staff,” said Peter.

Apart from saving the valuable timeof highly qualified staff, automatedarchiving provides efficient sampleretrieval in addition to full sample audit. The next part of the processmanagement procedure addressed the bottleneck encountered at the earlier stage of sample reception.

A familiar problem for this kind of lab is the sudden deluge of samples arriving in early to mid afternoonrequiring manual data entry of requests prior to processing.

Olympus PathRequest system hasalready been installed on two wards.This notifies the lab LIS system of allpatient and test request details so thatwhen the sample arrives in the lab asimple bar code scan is all that isrequired prior to sample processing.This improves patient safety andremoves the possibility of transcriptionerrors. Peter added, “This has provedto save valuable time at data entry andwill soon be extended to other wards.”

Trainees Committee Trainees Committee Trainees Committee

In keeping with tradition, the Monday evening of the ACB NationalTraining course in Guildford was devoted to the trainees. The TraineesCommittee excelled themselves in providing two high quality speakers –

David Cassidy, Chair of the ACB Education Committee and the ACB’sEuropean Officer Mike Hallworth.

The Education Committee ExplainedDavid Cassidy began the evening by giving the trainees a valuable insight intowork of the Education and the Regional Tutors Committees. He also flatteredthe trainees by noting that the competition for places in grade A schemes wasas high as ever and that the high calibre of recruits could only be a goodthing for the future of the profession.

Future ACB National Training CoursesIt is a great belief of the Education Committee that trainees should play amajor role in the shaping of their training. This opportunity was sought toobtain ideas and feedback from the trainees about the organisation of thecourses, update sessions and training days.

Trainees felt that the numbers on the course and the overall level ofteaching was appropriate. Planned expansion of the number of placesavailable on future courses was thought to be an excellent idea- as long assupply met demand! This expansion may make workshops difficult toorganise, but these should still be possible.

There were mixed views on the suitability of the course for first year GradeA trainees. Some felt that that the level was too high and these trainees wereperhaps blocking the access to the course of those about to take the MRCPathPart 1 exam. Others, however, thought that if funding was available then itshould be used. In addition, as the courses are on a 3-year cycle, traineesshould start early if they plan to take the exam at the end of Grade A training.

Paediatric TrainingSome trainees felt that there should be more dedicated paediatric trainingdays. The Education Committee is working with the new National MetabolicBiochemistry Network to provide specific training for paediatric trainees.Everyone agreed that while it would be good to include more specialist areasin the National Training Courses there is a huge amount of information to becovered in only six courses!

Developments in EuropeAfter displaying an encyclopaedic knowledge of the member states of the EU,Mike Hallworth dispelled the myth that Europe was all about “Drains inSweden” by explaining EC4!

The European Communities Confederation of Clinical Chemistry andLaboratory Medicine (EC4) was founded in 1993. Its main goal is toimprove the quality in clinical chemistry laboratories across Europe.This is mainly achieved through the harmonization of clinical chemistryin the EU and Europe – and as Mike pointed out, since May 1st thesetwo are now virtually the same!

The activities of EC4 are mainly split into two – the training andregistration of professionals and the accreditation of laboratories. EC4has produced a common syllabus across Europe for the training ofclinical chemistry staff. Although personal EC4 registration is voluntary,the trainees present were interested to hear how they could get involved.As Mike explained, it takes a minimum of 8 years from entry touniversity to become eligible for EC4 registration, but once gained itallows you to work in any EU country.

At the end of a long day Mike gave such a great explanation of recentdevelopments in Europe that the trainees for once were silenced butthen again, as Mike said, “Europe always silences everyone!” ■

MRCPath MRCPath MRCPath MRCPath MRCPath MRCPath MRCPath

With all due respect to William Marshall’s excellent series ofarticles on how to prepare for, and succeed in, the MRCPathexams I felt that there was something missing, namely a true

sense of what it is like to prepare for and sit these exams. This perspective can only be given by somebody who has recently gonethrough the experience of the MRCPath exams. So, to this end, I havewritten my own survival guide to MRCPath Part 1. I hope that it mightbe of some small help to those poor souls who can no longer put offhaving to face the exams, and at least give them an idea of what toexpect, or at the very least provide them with an excuse to stop revisingand read something else for a few minutes.

The opinions expressed are of course my own…

Expect a Severe ReactionLet’s not mince words, the Part 1 exams are going to be one of theworst experiences of your life. It is likely that you have never beforehad to revise so much material in such detail. You continue working fulltime and still have to find time to feed yourself and keep the houseclean. If you have a spouse and/or children you are really in trouble. Butit has to be done and no amount of procrastinating will change that.However, there are several essential psychological phases that you mustgo through first, before you can hope to do anything constructive.

Phase 1 . . . ExasperationThe standard advice is to start planning and preparing as soon aspossible. Read past papers, search out useful review papers, get a feel forthe size of the task and how you are going to go about it. You cannotdo this too early because, frankly, you are going to need time to get overthe reaction this process will provoke in you. Most will experiencesevere exasperation when they realise the huge range of subjects candidates are expected to know about in detail. This is made worsesince much of it is, in your opinion, irrelevant to your everyday work.This especially applies if you work in a children’s hospital. At this pointyou feel the urge to rant and rave about this to anybody who will listen,or can’t escape. Yes, you need to get it out of your system before youcan move on to the next stage.

From Despair to MotivationDespair sets in when you realise that ranting and raving isn’t going tochange anything. At this point you may find yourself contemplating achange of career, something with a few less exams perhaps and I seriously considered opening a bookshop at this point. Bear with it

though, you will eventually realise that having come this far it’s a bit latenow to start again. Anybody who has survived three terms in a studenthall-of-residence with a bunch of noisy undergraduates whilst on theGuildford MSc course will have the added incentive of not wanting tohave gone through all that for nothing.

If you are lucky, you will now find some motivation. However, motivation is fragile and needs to be nurtured. Try thinking about theconsequences of not doing the exam and being stuck in a career deadend, or worse still, of sitting the exam, failing and having to do thatrevision all over again. This should encourage you to do some properrevision, rather than just going through the motions.

Getting StartedHere are a few tips for getting started:

• Accept now that you will partially lose your sanity for the duration.Don’t fight it, it’s a waste of energy. If you aren’t talking to yourselfby the time you actually get to the big day itself then you eitheraren’t human or you haven’t been working hard enough.

• Say goodbye to family and friends, you won’t be seeing them for awhile.

• Explain patiently to your loved ones that them telling you not toworry too much because you have never failed an exam before isnot helpful. Your response to this is to say that while it is true thatyou have never failed an exam before you have never sat theMRCPath Part 1 before either. I also found it helpful at this point topoint out that I did actually fail my driving test the first time round.

• If you can draw up a revision timetable without freaking yourselfout too much then it’s quite a good idea to come up with one. Butdon’t worry about this too much, it is far more important at thispoint to just get started, worry about the details later. But not toomuch later!

RevisingHopefully you are now in a position and frame of mind to get down tosome serious revision. To be honest there isn’t much I can say at thispoint that will be of any help, or that hasn’t already been covered inWilliam Marshall’s articles. One thing that I would say is that you shoulddefinitely take any opportunity to practice past practical and writtenexam questions or any offers of tutorials and the like. However, in theend nothing can change the fact that you will have to put in hours andhours of frequently mind numbing revision. There is no real short cutor trick.

Next month Claire has exam day blues! ■

Arthur Walker was one of the brightest clinical biochemists of hisgeneration. Born in July 1940, the son of a local solicitor, Arthurwrote his PhD on acid-base metabolism at Aberdeen University

where, on its completion, he was immediately appointed to an assistantlectureship. He came south in 1966 to a job at Charing Cross HospitalMedical School where, working with John Daly and Tony Pollard, hedeveloped an interest in clinical enzymology. He soon attracted theattention of the then leaders of the profession because of his ability andpersonality. Shortly after taking up a senior post in Norwich, Ron Nunnpersuaded him to apply for the newly established top-grade biochemistpost in Guildford where I had recently become Professor. Despite being by far the most junior of all the applicants the appointments board had nodifficulty in electing him to become, at 32, the youngest holder of thegrade anywhere in the country. He was immediately accepted by thehospital’s Medical Advisory Committee as a full member - unusual inBritain for a Clinical Scientist at that time - and thereafter played an activepart in the management of the hospital as well as of the laboratory until hisretirement almost 30 years later.

Trace Metals LaboratoryUnder Arthur’s guidance the Guildford laboratory went from strength tostrength and was one of only two in the country to house three SASlaboratories one of which, the trace metals laboratory, he headed from thetime of its inception until he retired.

Besides playing a leading professional role within South West ThamesNHS Region, Arthur served the ACB well. He was an examiner for the MCBand later for the MRCPath. He served as Treasurer of the Southern Regionfor a time and chaired the Scientific Committee for one of the early Focusmeetings in Brighton.

Arthur was an Honorary Senior Lecturer in the Biochemistry Departmentat the University of Surrey and played an active part in the organisation andteaching of the department. Amongst his many protégés are some of thecurrent leaders of our profession, including Janet Smith, Andrew Taylor,Stephen Halloran, Sue Martin, and others, both medical and non-medical,too numerous to mention.

became Clinical Director when this post was instituted under one of the NHS re-organisations. Under his guidance the two laboratories inGuildford and in Frimley were merged and he became its first ClinicalDirector until he retired in 1999. This was an extremely stressful periodfor him and unquestionably put a strain on his health.

Arthur was an excellent conversationalist, very perceptive, a goodraconteur and only slightly more intolerant of stupidity in others thansome of us. Although always innovative in his own right he was theideal person off whom to bounce radical proposals as you couldguarantee that he would give a carefully considered and rationalresponse – but not always the one you wanted to hear. He was wellinformed about all manner of things and a most convivial colleaguewith whom I and others spent many a pleasant hour putting the worldto rights over a pint of beer at the Sandford Arms before going homeafter work.

Friends in and outside the laboratory held Arthur in high regard, andwith affection, and after a committee meeting you always knew whichpapers were his; they would be covered with sketches of aircraft whichhe was adept at drawing and were a life-long interest. More athletic thansome of us, he took up jogging, cycling, squash and swimming in hisearly 50s and on his retirement threw himself wholeheartedly into hispassion for engineering, especially of model railways. He soon becameinternational editor of its leading journal – and loved it.

Arthur died peacefully in his sleep the day after he had returned froma four-day conference on model railways in the Netherlands. It was aprivilege to have known him and enjoyed his friendship. His manyfriends both inside and outside the profession will miss his wisecounsel. Their hearts go out to his wife Jennifer and his two sons, Benand Andrew, of whom he was justifiably extremely proud but, inkeeping with his personality, never boastful.

Challenging Errors and

Editors to the Power of TwoDeacon’s challenge No 34 answer published inACB News January 2004I thank David Lyon for pointing out the two errorsunder the square root sign in the solution to thequadratic equation (line 9 page 12):

I did supply the editor with (1 x 10–8) raised to thepower of 2. The error presumably occurred duringediting (I never see the proofs!).

Since (1 x 10–14) is negative, the minus sign shouldbe positive (multiplication of two minuses gives aplus) which gives a final answer of 6.98. Alas, thiserror was all mine!

There is a third error which he failed to spot. 10–6

in the final line should read 106!Working out the terms under the square root sign

gives the awkward number 4.01 x 10-14, which mostcalculators cannot handle. The trick is to do this intwo parts. Using a calculator the square root of 4.01is 2.002. The square root of 10-14 is 10-7 (since –7 isthe logarithm to the base 10 and the square root of anumber is obtained by dividing its logarithm by 2).Combining these two values gives 2.002 x 10-7 forthe square root of 4.01 x 10-14.
