The Bupa Cromwell Hospital magazine for General Practitioners Issue 09 Published May 2014 In this issue Chronic Cough and the ENT Surgeon Transforming the Diagnosis and Treatment of Prostate Cancer Dupuytren’s Disease Primary Hyperparathyroidism NEWS WELCOME Welcome to the ninth issue of MEDIscene, which contains in-depth articles from some of our leading consultants, a larger news section and profiles of our Palliative Nurse Specialist and a highly regarded Ophthalmic Surgeon. Philippa Fieldhouse It’s been a busy few months at the Cromwell; we’ve launched a new Paediatric Walk-in Centre, introduced a Tilt table service and developed our Prostate Service and multi-disciplinary team. Consultant Urologist Mr Hashim Ahmed, who contributes an article on diagnosis and treatment of prostate cancer in this issue, is closely involved with the Prostate Service. Other articles include an overview of Dupuytren’s Disease by Consultant Hand and Orthopaedic Surgeon Mr Maxim Horwitz, Mr Gupreet Sandhu’s detailed look at the treatment of chronic cough, and Consultant Endocrine Surgeon Mr Fausto Palazzo’s very informative piece on primary hyperparathyroidism. We always welcome feedback and would be very pleased to receive your comments about the magazine, or thoughts on the hospital’s services. Please contact our GP Liaison team (details below) to pass these on. I hope that you enjoy this issue, and look forward to seeing you at one of our upcoming GP symposium events (listed on page 13). With warm regards, New Prostate Service Our new Prostate Service is now up and running at Bupa Cromwell Hospital, offering very accurate diagnostic testing and highly effective treatment. Diagnosis The unit offers multi-parametric MRI prior to decision about a biopsy, and targeted transperineal image-fusion prostate biopsy. Men with an elevated PSA blood test will undergo clinical review and examination followed by a high quality multi-parametric MRI of the prostate. This is followed by targeted biopsies (taken through the perineal skin rather than back passage) to areas of suspicion. The test is a safer, more accurate and less painful test than the standard Transrectal Ultrasound Guided Biopsy. Treatment A multi-disciplinary team of urology, oncology, radiology and histopathology specialists will review each case of prostate cancer to recommend treatment options, which may include:HIFU (Focused Ultrasound): focal therapy and whole-gland therapy. Cryotherapy: focal therapy and whole-gland therapy. Active surveillance with repeat multi-parametric MRI +/-targeted biopsy when appropriate. Philippa Fieldhouse General Manager Bupa Cromwell Hospital Key links with oncologists and surgeons performing radical prostatectomy for those requiring or choosing to undergo these procedures. GP LIAISON TEAM Richard Longes Laxmi Sonara Following diagnosis, most men have a choice between active surveillance and radical surgery or radiotherapy. The latter improves survival by 3-5% over 10-15 years but carries side-effects such as incontinence, impotence and rectal toxicity due to damage of collateral tissue. Amisha Patel The GP Liaison team provides a bespoke service for GPs. We can assist you with any enquiries you may have, and help facilitate patient referrals via Cromwell Direct – 0800 783 9229. This is a dedicated line for GPs wishing to refer patients (both children and adults) for appointments with consultants, diagnostic tests and admission to the hospital. We are pleased to welcome Amisha Patel as a new member of our team. Amisha is the GP Liaison Assistant and will be the first point of contact for educational events including our Symposium series. We understand that our GP colleagues want to keep up to date with new treatments, diagnostics and services. Therefore, we work closely with our consultants, many of whom are from London’s top teaching hospitals, to coordinate our educational programme. Please see the health professionals area of our website for more information. We would also be happy to arrange a practice visit at a convenient time for you in order to: discuss the latest developments at the hospital explore how we can work together more effectively introduce new consultants If you would like to discuss your educational needs and arrange a practice visit, or would like further information about Bupa Cromwell hospital, please contact us: Laxmi Sonara Richard Longes +44 (0)20 7460 5909 07714 386 680 +44 (0)20 7460 5842 07743 884 513 [email protected] [email protected] Front Cover: Research into novel antibiotics, showing a technician innoculating a series of agar (culture medium) plates with bacteria, as part of research into new forms of antibiotics. Pellets of drugs under test are typically placed on the agar plate and inhibition of bacterial growth is looked for after the plates have been cultured. A bacterial inhibition zone appears as a clear, circular region around the pellet of an effective antibiotic. However, one of the consultants, Mr Hashim Ahmed (pictured) has pioneered the role of focal therapy using minimally-invasive ablative therapies which only target the areas of cancer, leading to a much lower incidence of side-effects. See his article on page 11 for more details on this. The new Prostate Service also offers effective treatment for radiorecurrent prostate cancer as well as lower urinary tract symptoms, benign prostate hyperplasia, bladder outlet syndrome, urethral stricture and haematuria. Improvements to our Well Woman Clinic Bupa Cromwell Hospital’s Well Woman Clinic offers everything from routine check-ups with highly skilled consultants and specialist nurses, to diagnostic investigations (including bone density scans and mammograms) and treatment, all in one convenient location. We recently installed a new Vacuum Assisted Breast Biopsy unit (VABB), which provides an improved breast imaging service at the Well Woman Clinic and greatly reduced recovery times. The VABB procedure is carried out under local anaesthetic and leaves only a small incision that does not require stitches, offering patients a much less invasive alternative to open surgical biopsy. VABB retrieves larger amounts of tissue for diagnosis than surgical biopsy, and the procedure takes less than an hour. Patients can return to normal activities straight afterwards.

MEDIscene - ISSUE 09 08 cromwell direct 0800 783 9229 NEWS NEWS Lung Cancer Screening Tilt and Syncope Service Bupa Cromwell Hospital offers a dedicated lung cancer screening service, aimed at men and women from the age of 50 who are current or previous smokers. We have just launched a new Tilt testing service. This non-invasive procedure can help to diagnose patients with unexplained syncope when a cardiac arrhythmia is unlikely. It does this by confirming or refuting a neurally-mediated or postural cause of syncope by tilting the patient from a horizontal position to an angle of 60 degrees (head up) on a specially designed bed. Heart rate, beat to beat blood pressure and symptoms are monitored through this process. Would you benefit from lung cancer screening? Lung cancer is the leading cause of cancer deaths in both men and women. By the time symptoms develop it is often late in the disease and much harder to treat. A CT scan shows an abnormality in around one in four heavy smokers, and early detection of lung cancer saves lives. Regular screening over the age of 50 can give you peace of mind or provide early detection of lung cancer. Five minutes of recumbent data is recorded before the table is tilted upwards. If, within 20 minutes of tilting, no symptoms or a typical cardiovascular response (eg. hypotension, bradycardia) are induced, then sublingual nitrates are administered and data is recorded for another 20 minutes. If there are still no symptoms, bradycardia or hypotension apparent after this then carotid sinus massage is performed to provoke a response. At the end of the test, or when the diagnosis is achieved, the tilt table is returned to the horizontal position. Personalised specialist service We have a team of dedicated lung specialists, including chest radiologists, chest surgeons, chest physicians and chest pathologists all under one roof. Combined with our dedicated lung function laboratories, this means that results will be obtained quickly and you can be confident of experiencing a high quality, personalised service. Lung screening appointment During your appointment, which will normally last 2 hours, you will undergo formal lung function testing and a CT scan. The CT scan will be interpreted by a chest specialist radiologist and you will meet Mr Eric Lim, Consultant Thoracic Surgeon, who will document your risk factors, discuss the results of the CT and lung function and offer advice. If you need further treatment, the consultant is able to arrange any further tests or quickly refer you to the right specialist at the Hospital. We use the very latest screening technology - a GE 128 slice CT scanner which is designed to minimise your exposure to radiation. The test is performed as an outpatient investigation in a designated Tilt testing room in the Cardiology department, and is available Monday to Friday 9:30am - 7:00pm. The lung screening service is offered at a fixed price of £1,500. Please contact our Lung Screening Coordinator on +44 (0)20 7460 5836 or email [email protected] for further information. Referrals made by a non-Cardiologist/ Neurologist will require a full syncope assessment by a Consultant Cardiologist specialising in VasoVagal Syncope. This will include a clinical assessment with Carotid Sinus Massage (if appropriate), 48 hour Holter monitoring, ECG and Tilt test. Gamma Knife - still the gold standard for treating brain tumours Appointments are available Monday to Friday 9:30am - 7:00pm. Please contact +44 (0)20 7460 5755/6 or email cardiologydept@ cromwellhospital.com Our Gamma Knife Centre opened in 1998 and was the first in London. Used to treat both benign and malignant conditions affecting the brain, head and neck, Gamma Knife allows for shorter hospital stays and has an excellent success rate. Over 2,000 patients have been treated at the Cromwell. Professor Christer Lindquist and Professor Bodo Lippitz lead the service and have over 45 years of Gamma Knife surgery experience between them. What does Gamma Knife surgery involve? The patient is fitted with an aluminium head frame and the area to be treated then mapped using the latest in neuro-imaging techniques. The optimal dose of radiation is then delivered to the exact shape of the tumour through focused beams which are accurate to within 0.5mm – the width of a human hair. NEW CONSULTANTS Bupa Cromwell Hospital gives a warm welcome to the new consultants who were recently granted practice privileges. Our consultants are committed to an extremely high level of care and provide an excellent service to our patients. We are delighted to offer the innovation and expertise of the following new consultants at the hospital: Dr Adil Ajuied Consultant Orthopaedic Surgeon Adult Privileges Mr Eric Alexandre Chung Consultant General Surgeon Adult Privileges Benefits for the patient:- Mr David Hargreaves Consultant Trauma and Orthopaedic Surgeon Paediatric Privileges •non-invasive • no incision; no need for head shaving; no scars to heal •no hair loss or nausea • fast recovery time – patients can usually resume normal activity in a day or two Mr Giles Heilpern Consultant Trauma and Orthopaedic Surgeon Adult Privileges Mr David Houlihan-Burne Consultant Trauma and Orthopaedic Surgeon Adult and Paediatric Privileges Dr Bruce Martin Consultant Anaesthetist Adult and Paediatric Privileges Dr Ahmed Massoud Consultant Paediatrician Paediatric Privileges Mr Edward McKintosh Consultant Neurosurgeon Adult Privileges Professor Abhiram Prasad Consultant Cardiologist Adult Privileges Mr Andrew Ramwell Consultant General Surgeon Adult Privileges Miss Iman Riad Consultant Gynaecologist Adult Privileges Professor Lindquist comments; “Gamma Knife treatment is so effective as it is very focused on the tumour. Breast cancer patients can live many years if their secondaries elsewhere are well controlled, but if brain tumours aren’t treated patients can die within months, and this is the most effective way to treat those tumours. Since July 2003, the London Specialised Commissioning Group has recommended the Bupa Cromwell Hospital Gamma Knife Centre to provide radiosurgery for NHS patients.

The contraction leads to multi-level deformity with a loss of function. It is more common in males and usually affects patients over the age of 40, often presenting between 50 and 70 years of age. It is commonly bilateral. There is a hereditary predisposition for it and an association with diabetes and epilepsy, as well as Nordic ancestry, and it can be precipitated by trauma. There is a small group of people who have what is known as a Dupuytren’s diathesis, in which the disease progresses rapidly. Patients are usually male and present at a younger age with more severe disease. The diathesis is associated with a similar condition on the soles of the feet as well as Peyronie’s disease. Early on patients with this progressive disease present with pitting, nodules and thickening of the fascia in the hand, which can be painful and may irritate when the hand is used for grasping or holding objects. Later on this progresses to deformity at both the metacarpo-phalangeal (MCPJ) and proximal inter-phalangeal (PIP) joints. Another sign is the thickening of the skin over the back of the PIP joints - known as Garrod’s knuckle pads. Patients may tell you that they are having trouble with washing, as the finger gets in the way. Early referral of the condition is recommended so that fixed contracture can be prevented. Surgery is not recommended for very early disease (nodules and pits with no deformity) as this can exacerbate the diseases. Surgery is recommended when deformity occurs. This is usually when the MCPJ contracture is 30° or beyond with any contracture of the PIPJ. Range of movement can be assessed grossly and by using Hueston’s table top test, which says that if the hand can’t be put flat on a table then it needs surgery. It must be noted that surgery does not prevent a recurrence of the disease, and if there is also significant contracture of the joints then a full correction of deformity may not be possible. The following is a useful examination strategy for these patients: Treatment options: Ask them to show the palms of their hands and straighten their fingers. Dupuytren’s disease cannot be completely cured but two main treatment options are available; surgery and collagenase injection. Look and feel to establish: which fingers are affected degree of MCP and PIP flexion cords and pits nodules or palpable masses scars of surgery including previous skin graft webspace contractures dorsal hand: Garrods pads other sites: feet (Ledderhose Disease) and penile involvement (Peyronie’s) MEDIscene - ISSUE 09 Management: Surgery takes place under a regional block or a general anaesthetic as a day case. The patient goes home in a bulky dressing and will usually commence hand therapy within a week. Sutures are removed at approximately 12 days and a splint may be needed for the day and night for between four and eight weeks. Another option is Collagenase injection with subsequent manipulation. Collagenase clostridium histolyticum (such as Xiapex or Xiaflex) is a new medicine for the treatment of contractures caused by Dupuytren’s disease. It may not be appropriate for every patient and is best suited for localised cords over one joint. Patients undergo an outpatient injection with a follow up 24-48 hours later and a manipulation under local anaesthetic. They then see the hand therapist and may well need a splint but do not have a significant wound. There is often a small skin slit after manipulation. As always, patient choice, severity of disease and surgeons experience will play a role in the ultimate treatment decision. Long-term follow up is recommended as recurrence and new lesions can occur a long time after treatment.

It seems to affect women more than men. Chronic cough often starts with a ‘cold’ or ‘flu’ like illness, but the cough persists beyond the acute phase of the illness. It is possible that one or more pre-existing factors such as gastro-oesophageal reflux or post-nasal drip, whilst not previously sufficient to initiate a cough, now help to perpetuate it in combination with the trauma to the larynx from the physical act of coughing. This chronic airway inflammation, perpetuated by multiple aetiologies, has been termed a ‘cough hypersensitivity syndrome’. The concept of a hypersensitised larynx serves as a good model when advising patients on a treatment plan. It is also important to bear in mind the concept of ‘one airway, one disease’, which considers the upper and lower airway as a continuum and accepts that pathology in one site may affect others. The most common causes of chronic cough are post nasal drip (PND), asthma related syndromes and gastro-oesophageal reflux disease (GORD). GPs usually refer patients with a persistent cough to an ENT specialist after lower respiratory tract pathologies have been excluded, to determine if the cause is related to PND or GORD. This can be difficult as some patients exhibit clear symptoms and signs whilst others have none. A careful history needs to be taken by the specialist followed by an examination, including endoscopy of the nasal cavity, larynx and pharynx. A chest X-ray will be requested, if not done already, with referral to a respiratory physician as findings dictate. Skin allergy tests will be performed where there is suspicion of allergy, and a CT scan may be advisable for patients with sinus symptoms. A gastroenterology referral is made either when a patient reports symptomatic severe reflux, or a definitive trial of medical therapy has failed to bring about relief. Where there is concern about the safety of swallowing, or oesophageal dysmotility is suspected, then a Video Fluoroscopic assessment of swallowing is recommended. In the absence of pathology, a cough that fails to resolve spontaneously or in response to definitive medical treatment may be described as idiopathic, however some of these cases will be psychogenic. Some reports suggest that up to one third of cases are idiopathic, but in my experience the incidence is much lower. Chronic cough is defined as lasting longer than eight weeks and is experienced by approximately 40% of people at some stage in their lives. It seems to affect women more than men. Post Nasal Drip Photo - Science Photo Library Secretions from the nose (20–40 mls each day) commonly enter the pharynx, through the ciliary action of the nasal mucosa, and are swallowed. Post-nasal drip however is when patients report having the sensation of mucus tracking down into the throat. Antihistamines should be introduced if symptoms of sneezing, itchy eyes and clear nasal discharge are evident. Laryngopharyngeal infections Upper respiratory tract infections are most commonly viral and are associated with inflammation of the larynx and pharynx. Treatment should be conservative as the majority of these infections resolve spontaneously with voice rest, steam inhalation and adequate hydration. Some may be bacterial however, and should be treated with antibiotics. Some cases of chronic cough may be due to a postviral laryngeal sensory neuropathy. Cranial nerves can be affected by inflammatory neuropathic processes, as seen in Bell’s palsy and trigeminal neuralgia. These can also result in altered sensory and motor nerve function. Sensory neuropathic cough is thought to correspond to the lowered threshold to stimuli seen in cases of trigeminal or postherpetic neuralgias. With the Vagus nerve this can lead to a ‘bogus tickle’ and uncontrollable coughing. These cases have responded to Amitryptilline, which may lower the sensory threshold for the afferent nerve endings but can also have a psychotropic effect. Laryngopharyngeal reflux Gastro-oesophageal reflux disease (GORD) is the cause of chronic cough in up to 40% of patients and diagnosis is based on well defined symptom scoring and 24 hour pH testing. Those who argue for different diagnostic criteria for laryngopharyngeal reflux (LPR), do so on the basis that the larynx is poorly protected against even transient reflux episodes and that the reflux material contains proteolytic enzymes and bile salts, both of which can cause laryngeal irritation. The gold standard for diagnosis of LPR remains multi-channel intraluminal impedance manometry. It is accepted practice to treat with a trial of proton pump inhibitors when suspecting reflux as a cause for chronic cough, resorting to further investigations if medical therapy fails. Aggressive treatment (twice daily) with a proton pump inhibitor may be necessary for three months to reverse the effects of LPR. An alginate, such as Gaviscon Advance, should be used after the evening meal to deal with the non-acidic components of the refluxate. Rhinological conditions associated with post-nasal drip include allergic rhinitis, chronic rhinosinusitis and nasal polyps. Chronic rhinosinusitis is recognised as the main cause of PND and is defined as inflammation of the lining of the nose and paranasal sinuses. There has been much debate as to whether post-nasal drip is associated with chronic cough. It would be reasonable to expect that many patients with chronic rhinosinusitis would complain of PND and cough, yet very few do so. The American College of Chest Physicians recommend using the term upper airway cough syndrome (UACS) instead of PND, as conditions causing the syndrome, such as rhinitis, may be linked with coexisting inflammation of the larynx through the same aetiological factors. The treatment of PND is directed at the cause. Based on Allergic Rhinitis and its impact on Asthma, firstline treatment should be with intra-nasal corticosteroids (usually as a spray) for at least three months. MEDIscene - ISSUE 09 cromwell direct 0800 783 9229 Lifestyle changes are crucial and complementary in the long-term management of these patients. This often includes weight-loss, dietary changes such as limiting caffeine consumption and leaving two to three hours after the evening meal before sleep. BUPA CROMWELL HOSPITAL Severe cases of GORD related cough which don’t respond to medical treatment may be referred for antireflux surgery. NEW PAEDIATRIC WALK-IN CENTRE Dysphagia Any disturbance of normal swallowing may result in aspiration and chronic cough. However, poor clearance of secretions in the hypopharynx and dysmotility can have similar affects. A pharyngeal pouch must be excluded when considering the laryngopharyngeal causes of chronic cough and can be identified by a contrast study, such as a barium swallow. Airway Stenosis Laryngotracheal stenosis usually causes breathing difficulty and is associated with poor exercise tolerance, but it can also lead to a chronic cough. It is sometimes misdiagnosed as Asthma and causes can be congenital or acquired. In the adult population 50% of cases are related to ventilation on the intensive care unit. The diagnosis can be made on CT imaging or bronchoscopy, but flow volume loops are an excellent screening tool. Systemic inflammatory conditions The most common systemic conditions associated with cough are sarcoidosis and granulomatosis with polyangitis. The diagnosis is made based on the clinical picture, blood markers and histology. Mr Fausto Palazzo Head and neck conditions Benign or malignant lesions of the larynx may be associated with a cough. The management of these is beyond the scope of this article, but may include endoscopic or open surgical procedures, or radiotherapy. Psychogenic cough Much research has been undertaken investigating the role of higher brain areas in cough, however there is little systematic behavioural research on the role of psychological factors. Evidence supports the role of basic psychological processes on cough behaviour, cognition, emotion, learning and social factors are all thought to impact on this, but evidence is sparse. Photo - Science Photo Library - Nasal endoscopy The endoscope has been introduced into the patient’s body through his nose. It is a fibre optic cable that provides views of the body’s interior.

The ENT specialist needs to consider the upper and lower airways as a continuum, and independently understand the conditions that contribute to cough. Direct endoscopic examination of the nose, larynx and pharynx enable the identification of signs that would otherwise be missed. The management very much depends upon the aetiology and all potential causes should be treated aggressively and simultaneously. Coming into hospital can be stressful both for children and their parents, but Bupa Cromwell Hospital’s experienced paediatric team ensures the best possible care for children in a calm, comfortable environment. The team delivers a wide range of services for babies and children up to 16 years of age, from simple day case procedures to more complex treatment. We have launched a Paediatric Walk-in Centre for children with minor injuries and illnesses, giving parents and carers peace of mind with instant appointments and first class care. So you can now avoid NHS queues and get immediate out of hours treatment. Patients are seen by a fully qualified practitioner and pay a fee of £100 for an initial consultation, with further charges for extra treatment if necessary. No appointment is necessary, and patients have the benefit of being treated in a fully equipped private hospital, with instant referral to leading specialists if required. Minor injuries or conditions treated at the Walk-in Centre include: acute infectious illnesses cuts, abrasions, lacerations and wounds ear, nose and throat conditions feeding problems gastroenterological or respiratory illnesses general medical conditions Monday to Friday 5.00pm -9.00pm Saturday 10.00am -8.00pm Sunday/ Bank Holidays 10.00am -6.00pm t: +44 (0)20 7460 5878 e: [email protected] w: bupacromwellhospital.com/childrens-walk-in To make an appointment please call 0800 783 9229 MEDIscene - ISSUE 0X 09 cromwell direct 0800 783 9229 TRANSFORMING THE DIAGNOSIS AND TREATMENT OF LOCALISED PROSTATE CANCER be recommended conservative management in contrast to radical therapy, and men with low-risk disease are recommended radical therapy ‘just in case’. Three-quarters of men report at least one minor complication after prostate biopsy:- Risks and Complications from Transrectal Biopsy INFECTION Bacteriuria: 20%-50% Bacteraemia: 20%-70% Urinary tract infection: 1-8% Mr Hashim Ahmed Mr Hashim Ahmed PhD, FRCS(Urol), BM, BCh (Oxon), BA(Hons) is a Consultant Urologist at University College London and Bupa Cromwell Hospital The current diagnostic and therapeutic strategy for localised prostate cancer is not working. In fact it is severely flawed and fraught with controversy. This has not been helpful to patients who are considering entering the diagnostic pathway or who have, inadvertently, found themselves within it. Due to the random nature in which we carry out prostate biopsies there is inaccuracy in detection, localisation and characterisation of cancers. Much debate has centred on these errors, but what is clear is that current principles of diagnosis and treatment lead to significant harm with little benefit. Despite a general acceptance that these problems are real and serious, few corrections have been put forward to help mitigate them. That is, until now. The current strategy has arisen from our imprecise diagnostic pathway. We don’t know where the cancer is, so subject the prostate to randomly placed needles via a Trans Rectal Ultrasound (TRUS) Guided Biopsy in the hope of hitting the tumour. This leads to over-diagnosis, underdiagnosis, miss-classification of risk, and both over and under-treatment. If we do find cancer, we usually subject the entire prostate to radiotherapy or surgery, which damages surrounding structures like neurovascular bundles, the external urinary sphincter, rectum and bladder neck. If the benefit of treatment was significant, then the resulting 10% chance of incontinence, 20% chance of impotence and 10% chance of rectal side-effects (pain, bleeding, diarrhoea) might be justifiable. The benefit of radical therapy is small however, and although treating intermediate and high risk localised prostate cancer in this way could be justified (c. 5% absolute risk reduction in mortality at 10-15 years), there seems to be no benefit in survival for low-risk disease. Ultimately, TRUS biopsy performs poorly because it is conducted without knowledge of the cancer location. TZ Random deployment of the needle leads to a clinically important tumour being missed Figure 1. MEDIscene - ISSUE 09 Ultrasound is used simply to determine that the needle has targeted prostate tissue, and as a result these biopsies over-diagnose clinically insignificant prostate cancer. A man who undergoes transrectal biopsy has a one in four chance of being diagnosed with prostate cancer, yet most of these cancers will be the indolent type that men die with, not from. Conversely, transrectal biopsies miss clinically significant cancers, (Figures 1-3). Due to their random nature, they have an estimated false negative rate of one in three. Men who test negative for prostate cancer are either discharged to the community for yearly PSA testing, or the same unreliable and harmful test can be repeated several times over a number of years in one man. BLEEDING Systematic error leads to a clinically important tumour being missed higher up in the prostate Random deployment of the needle leads to a clinically significant tumour being missed in the anterior TZ Random deployment of the needle leads to a clinically significant tumour being under-sampled and categorised as low risk Figure 2. Figure 3. Figure 4. Life-threatening sepsis: 1-4% Who should be referred for a pre-biopsy MRI and/or transperineal targeted biopsy at the Cromwell? Haematuria: 50% - Elevated age-specific PSA Rectal bleeding: most URINARY Acute urinary retention: 1%-2% Voiding symptoms: 10% - High PSA density 0.15ng/ml/ml if a transrectal ultrasound volume has been calculated - High PSA velocity. 0.35 ng/ml/year for PSA values <4ng/ml and 0.75ng/ml/year for PSA values >/=4ng/ml - Elevated PSA with first degree relatives with prostate cancer and/or ethnic risk eg. afro-caribbean/black men SYSTEMIC Vasovagal reaction 8% Imaging is redefining our pathway Magnetic resonance imaging can change all of this and improve the care we offer men. Multi-parametric MRI, (Figure 5), coupled with targeted biopsies, can rule out clinically significant lesions with a negative predictive value in the order of 90-95%. A number of trial groups have shown encouraging detection rates using multi-parametric MRI to target areas of suspicion. MRI can provide an accurate volume with indicators of higher Gleason grade prior to biopsy, and act as a triage test to identify those men who require biopsies. This allows men with no clinically significant cancer to avoid entering the pathway, avoid having biopsies and potentially unnecessary treatment altogether. Prostate cancer in left peripheral zone confirmed with targeted transperineal biopsies R= rectum R TZ TZ FOCAL THERAPY - Treating the tumour and not the whole prostate Haematospermia: 30% They can also be unrepresentative of the true burden of cancer, (Figure 4). One in three men deemed low risk on transrectal biopsies can have a higher volume or grade cancer, or both when a more accurate biopsy test is applied. The cancer risk attribution errors of transrectal biopsy result in inappropriate treatment allocation; men with high-risk disease might TZ anaesthetic; carrying out 100,000 biopsies in the UK or 1 million biopsies across Europe under general anaesthetic is not viable. However, subjecting a man to ‘transfaecal’ biopsies is questionable when an alternative is available. My research group has been the first to show that transperineal targeted biopsies under local anaesthetic are feasible, tolerable and accurate. They can be carried out in clean non-theatre settings at low cost, with each procedure lasting only 20 minutes. Red-line outlines prostate Figure 5. Once an image is available, targeting a suspicious lesion accurately is crucial. A number of trial groups conduct targeted biopsies transrectally, again traversing contaminated mucosa. Until now the alternative, transperineal biopsies, have required general - Normal PSA but abnormal free/total PSA ratio (defined by each lab but usually <25%) - Men advised to have repeat TRUS biopsy following a previous negative biopsy due to persistent indication - Men who are on active surveillance for presumed low risk prostate cancer - Men considering minimally invasive therapies such as HIFU or cryotherapy A dilemma awaits any man diagnosed with localised prostate cancer, as he will eventually be forced to choose between radical therapy or active surveillance. Radical treatment maximises the chances of cure, but comes with a 50% chance of serious impact on sexual and/or urinary function. With active surveillance, genito-urinary function is preserved in exchange for the psychological and healthcare burden of intensive surveillance. Compared to other malignancies, prostate cancer is an outlier. Breast, renal, thyroid, liver, and pancreas all involve tissue-preserving therapies, if appropriate, which are dependent on location and the burden of cancer. These areas of oncological surgery developed tissuepreservation, as opposed to Halsted principles for wider surgical margins, due to improvements in diagnostic tools which are reliant on finding measurable disease which undergoes targeted sampling and treatment. The transrectal biopsy has done the opposite for prostate cancer. Random blind sampling has forced our hands as clinicians so that we have to apply radical whole-gland principles. But this is changing. Studies show that it is sufficient to treat less than the whole-gland. This is called focal therapy, (Figure 6 - see over), and it leads to far less genito-urinary and rectal side-effects. There are currently two modalities approved by NICE in the UK for delivering focal therapy; high intensity focused ultrasound (HIFU) and cryotherapy.

I liked the idea of not doing the conventional nine to five desk job, so it was just a natural progression for me after leaving school. I did surgical nursing initially and became a midwife for three years, before coming to London. I began work here at the Cromwell 17 years ago on the oncology unit and have progressed in various oncology roles since then. H ow did you decide upon your specialism? I gradually developed into the role of palliative care and symptom control from being an oncology nurse. Some patients suffered with treatment side effects, and I became interested in supporting them. I carried out further study at King’s College, which enabled me to become the Palliative Care Nurse here at the Cromwell. W hat’s the difference between being a nurse, and being a palliative care nurse? Our 2014 series of lectures will be led by our renowned consultants, many of whom are from London’s top teaching hospitals, to bring you the latest updates and advances in healthcare. Topics have been tailored with primary care GPs in mind. Saturdays - 9.00am-2.00pm Kensington Town Hall 28 JUNE 20 SEPTEMBER W hat’s the best thing about your job?

My role is very much overseeing, signposting and planning a patient’s journey. Focusing on the care they may need after treatment, whether they are in recovery or in the terminal phase of their treatment. No two days are the same. For me, when you can give somebody in a vulnerable phase of their life what they want, and make things as stress free as possible for both them and their family, that is quite rewarding. then I do a ward round to check on all the patients, and if any need further care I arrange this. I organise referrals for patients to see dieticians or counsellors, or talk to family members if they want to discuss anything. I work with Macmillan and the benefits helpline, as some patients do not have plans in place for paying the mortgage etc. There is a degree of social work involved in my job and I spend a fair amount of time filling out forms for patients who may be struggling with bills or their employers. My afternoon is normally spent writing up notes and documenting patients’ progress. I meet with the Therapy department to see how patients are doing with mobility, and if any amendments need to be made to their care. I also educate staff on the wards to ensure they know the end of life care pathway at the Cromwell. I s this role different in the NHS to the private sector? The only difference is that I am the only palliative nurse at the Cromwell, whereas NHS trusts have a few in each hospital. W hat advice would you give to someone hoping to follow in your footsteps? to follow in your Get a good basic understanding of the treatments available for the different diseases as this gives good progression from being an oncology nurse into palliative care. H ow would a patient end up seeing a Palliative Nurse? I see oncology, cardiac and liver disease patients at the hospital, however I spend more time with those in declining health. Most of the time consultants will ring me if a patient is very unwell in order to begin planning the next phase of their treatment. W hat is an average day like for you? I begin my day by liaising with district nurses, cromwell direct 0800 783 9229 Primary Hyperparathyroidism Surgery for Primary Hyperparathyroidism Figure 1. Mr Fausto Palazzo Mr Fausto Palazzo MS FRCS(Eng) FRCS(Gen) is a Consultant Endocrine Surgeon at Hammersmith Hospital and Bupa Cromwell Hospital Primary hyperparathyroidism (pHPT) is the inappropriate excess secretion of parathyroid hormone (PTH) from one or more parathyroid glands in the absence of an external abnormality, such as renal failure. In pHPT one or more diseased parathyroid glands have escaped the normal negative feedback associated with hypercalcaemia, which normally leads to a decrease in PTH production when the serum calcium rises. This is the key distinguishing feature compared with other causes of hypercalcaemia. Figure 2. Table 1. Diagnosis of primary hyperparathyroidism Malignant hypercalcaemia pHPT Calcium Very high High Phosphorous Low Low or normal PTH Suppressed Inappropriately high Urinary Calcium High High The excess serum PTH culminates in hypercalcaemia due to: calcium mobilisation from bone increased renal re-absorption at the expense of phosphate indirect increase in gastro-intestinal calcium absorption Most pHPT occurs after the age of 45 and is sporadic, but the condition may occur in younger patients, when it is more likely to be associated with one of the Multiple Endocrine Neoplasia (MEN) or tumour jaw (HRPT2 mutation) syndromes. The incidence of the disease is rising due to an increase in average longevity and a higher detection rate. peak incidence between 50 - 60 years of age female to male ratio of 3.5:1 >85% of pHPT is caused by a single parathyroid tumour (adenoma) multiple gland disease (adenomas or hyperplasia) is encountered in up to 15% of MEDIscene - ISSUE 09 cases and can occur either sporadically or as a part of MEN I or II syndromes parathyroid carcinoma accounts for less than 0.5% of pHPT other than family history, radiation exposure, lithium use and chronic vitamin D deficiency, little is additionally known of the risk factors for pHPT The traditional clinical manifestations of pHPT are: bones: bone pain due to osteoporosis, pathological fractures or in extreme cases osteitis fibrosa cystica and brown tumours (Figure 1) stones: nephrolithiasis or nephrocalcinosis affect 20% of patients with possible alteration of renal function (Figure 2) Other clinical features include hypertension, gout, normocytic normochromic anaemia and subtle neurocognitive symptoms, which currently represent the most common manifestations of the disease. Untreated pHPT is associated with incompletely understood increased risk of mainly cardiovascular death and a significantly decreased quality of life. Treatment of Primary Hyperparathyroidism Surgery is the only definitive cure of hyperparathyroidism. The current international guidelines recommend parathyroidectomy in:all symptomatic patients irrespective of age evidence of end organ damage (osteoporosis/ nephrocalcinosis etc) asymptomatic patients that have one or more of the following: abdominal groans due to the effects of hypergastrinaemia or pancreatitis Markedly elevated serum calcium (>0.25mmol/L above normal range). psychic moans: multiple nonspecific symptoms are frequent and include depression, anxiety and cognitive difficulties Creatinine clearance reduced by 30% with age matched normal subjects. Age <50 years. The operative management of primary hyperparathyroidism has changed significantly since the first parathyroidectomy which was performed at the beginning of the 20th century. The operation, which could last hours and be full of pathological uncertainty, as well as lead to a prolonged length of stay, has been refined to become a safe operation taking a predictable length of time and only one night stay in hospital. The procedure has evolved over decades around the principle that abnormal glands are removed and the normal glands left in situ. The gold standard procedure of bilateral neck exploration has been joined by the co-gold standard of minimally invasive parathyroidectomy in appropriately selected patients. There is now rarely need for frozen section with either procedure. The neck exploration is reserved for patients with unlocalised disease but is performed via considerably smaller and more cosmetically acceptable scars than in the past. It allows the direct visualisation of all parathyroid glands and evidence suggests that in the hands of high volume parathyroid surgeons (>50 parathyroidectomies a year) it remains the approach that is associated with the highest cure rate from first time surgery. The advantages of this are: it allows the management of nearly all scenarios including multiple gland disease (double adenomas and hyperplasia), ectopic glands, supernumerary glands etc. it has minimal morbidity and no mortality Since over 85% of pHPT is caused by a single benign tumour however, the possibility of focusing on the removal of the single abnormal gland and avoiding extra dissection and manipulation of normal parathyroid glands has been seen as desirable. This is the conceptual platform on which focused/minimally invasive parathyroid surgery is based. Minimally invasive parathyroidectomy was, for many years, hindered by the lack of reliable pre-operative localisation methods. Sequential breakthroughs have now facilitated focused parathyroid surgery: cromwell direct 0800 783 9229 the arrival of Tc-99m Sestamibi scanning (Figure 3) improvements in ultrasound scanning and radiological specialisation the development of intraoperative quick PTH with a two-site antibody immune-radiometric assay popularised by Irvin in Miami. 4D CT - the latest state of the art imaging modality for selected cases (Figure 4) Mr Naresh Joshi DO FRCOphth, Consultant Ophthalmic Surgeon M r Naresh Joshi is a Consultant Oculoplastic surgeon at Chelsea and Westminster Hospital NHS Trust, and Honorary Consultant to the The Royal Marsden NHS Foundation Trust.

Secretary: Wendy Addison T: +44 (0)20 7460 5739 Why did you study medicine? I have two doctors in my family so was guided into medicine as a potential career. I knew their lifestyle and often accompanied my father to the hospital. That’s what initially gave me the idea about going into medicine. Figure 4. Minimally invasive parathyroidectomy Various minimally invasive parathyroidectomy (MIP) techniques exist, and almost all have been used by the author. The principle of the surgery remains the same irrespective of the approach – the removal of a previously localised parathyroid adenoma via: •focused lateral mini incision What made you pursue your speciality? Figure 3. suspicion of carcinoma morbid obesity Intraoperative PTH may offer additional benefit to the surgery although this is less valuable to the patient than surgical expertise and practice volume. •endoscopic assisted •radio guidance •video assistance Cure is denoted by the “Miami criteria” of a drop of 50% or more from the highest value of PTH encountered perioperatively (either pre-operative baseline or pre-excision) 10 minutes after removal of the diseased gland. Failure for the PTH to fall suggests multiple gland disease and the need for four gland exploration. •robotic Conclusions primary hyperparathyroidism is increasing in incidence and has detrimental effects beyond bones, stones and moans, including cardiovascular illness and quality of life Figure 5 In addition to unlocalised disease there are some patients that should not have minimally invasive parathyroid surgery: history of neck irradiation and prior neck surgery What is the most challenging part of your job? The most challenging part of the job is dealing with difficult individuals as opposed to difficult cases. Difficult cases can be worked out technically, but difficult individual demands that are beyond normal expectations are more challenging. What is the most rewarding part of your job? standard parathyroid surgery is now performed via very small incisions When patients are grateful and happy; when they receive the outcome that they wanted. Patient gratitude is by far the greatest joy. parathyroid surgery is associated with 98% cure rates even in the absence of localisation when performed by high volume parathyroid surgeons concomitant multinodular goitre or autoimmune thyroiditis (relative contraindication) diagnosis of Multiple Endocrine Neoplasia Type 1 To make an appointment please call please call 0800 783 9229 One of the things that we do is charitable work. I work with Facing the World, a charity which helps children with facial deformities. The Cromwell has been very supportive of Facing the World and it’s the charity that I actively support and am involved in. What do you enjoy doing in your spare time? Consultant parathyroid imaging has made minimally invasive parathyroidectomy the co-gold standard Mr. Palazzo’s practice is entirely related to thyroid, parathyroid (over 160 parathyroidectomies a year) and adrenal surgery. MEDIscene - ISSUE 09 Once again I have two ophthalmologists in my family, so was inspired by them. My own speciality is very different to theirs however; they are general ophthalmologists whilst my speciality is Oculoplastic surgery. This includes a wide variety of surgical procedures that deal with the eye socket, eyelids, tear ducts, and the face. Can you tell me about a project that you consider to be significant to your career? Can you describe a typical working day? A typical day at the Cromwell - on Tuesday mornings I have porridge for breakfast with my wife and then walk to the hospital. I arrive around 7:45am and start my operating list at 8:00am. That carries on until around 1:30pm when I’ll have salad for lunch (I like to be healthy). I then run a clinic, seeing patients from 2:00pm to 5:00pm at the hospital. I am home in time for supper at 6:00pm with my wife and children. We travel a lot - I lecture in about 10 different countries a year. In terms of sport I walk a lot and enjoy playing golf... I also have a passion for wine! What is your most prized possession? My most prized possession is my family. Where is your favourite place in the world? My favourite place in the world is home. The best soundtrack for a dinner party is...? Depends what sort of dinner parties I have! We usually listen to something classical; my wife is very into opera – so it’s usually something that she chooses! If you had one super power what would it be and why? I would like the power to put more smiles on people’s faces. I would like more people to be kind and content. There are many people who are not kind enough or content with their lives. I would have the power to make people happier! If you could be any biscuit, what biscuit would you be and why? I would be a chocolate bourbon because it’s indulgent, and has a soft centre, like me. If you were a movie character who would you be? A movie character – I would be Robert Redford because my wife fancies Robert Redford!
