With mitral valve prolapse depression definition business buy discount amitriptyline 10 mg line, regurgitation begins in early or midsystole producing a pan or late systolic murmur (see Fig mood disorder videos cheap 10mg amitriptyline overnight delivery. Small congenital defects produce a loud murmur audible at the left sternal border depression symptoms shortness of breath safe amitriptyline 25 mg, radiating to depression symptoms blurred vision order 75mg amitriptyline mastercard the right sternal border and often associated with a thrill. Rupture of the interventricular septum can complicate myocardial infarction and produces a harsh pansystolic murmur. Other causes of a murmur after myocardial infarction include acute mitral incompetence due to rupture of a papillary muscle or functional incompetence caused by left ventricular dilatation. The pulse pressure is usually increased; the jet from the aortic valve is directed inferiorly towards the left ventricular outflow tract (arrow) during diastole, producing a high-pitched murmur which is best heard with the diaphragm. The diagrammatic representation of the phonocardiogram also shows the associated systolic murmur, which is common because of the increased flow through the aortic valve in systole. The term early diastolic murmur is somewhat misleading because the murmur usually lasts throughout diastole, but it is loudest in early diastole. They are heard at the left sternal edge (occasionally louder at the right sternal edge) and are most obvious in expiration with the patient leaning forward. Since the regurgitant blood volume must be ejected during the subsequent systole, significant aortic regurgitation leads to increased stroke volume and is almost always associated with a systolic flow murmur. It may be caused by pulmonary artery dilatation in pulmonary hypertension (Graham Steell murmur) or to a congenital defect of the pulmonary valve. A continuous murmur is heard because aortic pressure always exceeds pulmonary arterial pressure resulting in continuous ductal flow. The pressure difference is greatest in systole producing a louder systolic component to the murmur. It is best heard with the bell of the stethoscope at the apex with the patient rolled to the left side. If the patient is in sinus rhythm, left atrial contraction increases the blood flow across the stenosed valve leading to presystolic accentuation of the murmur. An Austin Flint murmur is a mid-diastolic murmur that accompanies aortic regurgitation. The commonest cause is a patent arterial duct, which connects the upper descending aorta and pulmonary artery in the fetus and normally closes just after birth. The murmur is best heard at the upper left sternal border and radiates over the left scapula. Examine the trachea and cardiac apex beat for mediastinal shift (tension pneumothorax). Palpate the epigastrium for tenderness (gastro-oesophageal reflux, peptic ulcer, oesophagitis). Listen to the heart for extra heart sounds or gallop rhythm (heart failure), pansystolic murmur radiating to the left axilla (mitral incompetence due to papillary muscle rupture post-myocardial infarction), pansystolic murmur at the left sternal edge (ventricular septal defect post-myocardial infarction) and pericardial friction rub (pericarditis). Interpretation of findings Auscultation remains an important clinical skill despite the ready availability of echocardiography. Furthermore, certain auscultatory signs, such as the third or fourth heart sounds and pericardial friction, have no direct equivalent on echocardiography but are helpful prognostically. Feel the pulse for bradycardia (faint or syncope; heart block or Stokes-Adams attack), (supraventricular tachycardia or ventricular tachycardia; sinus tachycardia after seizure) and irregularity. Examine for focal neurological signs (post-epileptic seizure, cerebral haemorrhage). Inspect the tongue for lacerations and check for urinary incontinence (post-epileptic seizure). Assess level of consciousness (epileptic seizure, subarachnoid haemorrhage, intracranial lesion). For example, a patient with mixed mitral stenosis and regurgitation will probably have dominant stenosis if the first heart sound is loud, but dominant regurgitation if there is a third heart sound. Patient-activated recorders are useful for capturing occasional arrhythmias and are activated only when symptoms occur (Fig. Increased in heart failure and valve disease Pulmonary oedema in heart failure Echocardiography Cardiac murmur Stenotic valve lesion readily diagnosed and accurately quantified Regurgitation readily detected with semiquantitative assessment Breathlessness Left ventricular function can be assessed. Transoesophageal echocardiogram is more sensitive Radionuclide studies Breathlessness Blood pool scanning provides an accurate assessment of left ventricularfunction, usually expressed as ejection fraction (end-diastolic volume end-systolic volume/end-diastolic volume) Chest pain Myocardial perfusion scan reveals ischaemic deficits in ischaemic heart disease Pulmonary embolism Lung scan shows a perfusion deficit compared with simultaneous ventilation scan Cardiac Angina Coronary angiography reveals the extent and severity of coronary stenoses. This catheterization determines the therapeutic approach Valve disease Better evaluated non-invasively by echocardiography. Cardiac catheterization is only indicated to assess the coronary anatomy in patients who require heart valve surgery Heart failure Right heart catheterization in patients with severe heart failure helps determine suitability for cardiac transplantation page 107 page 108 Figure 3. In heart failure this is often accompanied by distension of the upper lobe pulmonary veins, diffuse shadowing within the lungs due to pulmonary oedema and the finding of Kerley B lines (horizontal engorged lymphatics at the periphery of the lower lobes) (Fig. Echocardiography was originally devised to evaluate valve abnormalities, but is now most commonly used to assess left ventricular function. In addition to imaging cardiac structure, blood flow can be displayed (Doppler echocardiography), and analysed to quantitate valve stenosis and regurgitation. Most scans are performed through the anterior wall of the chest (transthoracic) but when high-resolution images of posterior structures. This can be carried out safely in outpatients using topical anaesthesia and intravenous sedation (Fig. Radionuclide studies Radionuclides are injected intravenously and detected using a gamma camera. Technetium-99 is used to label the circulating blood and provide an accurate assessment of left ventricular function. Cardiac catheterization this invasive procedure involves introducing fine catheters, approximately 2 mm in diameter, into the femoral (or radial) artery and/or vein, and advancing them to the left or right side of the heart respectively. Originally these techniques were developed to measure pressures in the different cardiac chambers in patients with valve disease. Coronary angiography is performed using catheters designed to select the left and right coronary arteries and inject X-ray contrast medium into them. The findings are used to determine the need for, and mode of, revascularization in patients with coronary artery disease (Fig. This shows thinning of the interventricular septum, which has an irregular shape and bright echoes indicating fibrous scarring. Integration link: Atherosclerosis natural history Taken from Robbins & Cotran Pathologic Basis of Disease 7E? Check the heart rate by auscultation and look for evidence of an underlying cause thyrotoxicosis, hypertension, alcohol abuse, valve disease, and heart failure. Recurrent chest pain unresponsive to glyceryl trinitrate is very unlikely to be angina. In the great majority of cases the underlying pathology is atherosclerosis affecting large and medium-sized vessels. The identification of patients with peripheral arterial disease is important because: peripheral arterial disease is a marker for premature cardiovascular and cerebrovascular death if not recognized, the first manifestation of peripheral arterial disease may be a life or limb-threatening complication such as stroke, acute limb ischaemia or ruptured abdominal aortic aneurysm modifying vascular risk factors improves outcomes peripheral arterial disease may affect medical and surgical treatment for a range of other conditions. Common symptoms There are four major ways in which peripheral arterial disease patients may present: limb symptoms neurological symptoms abdominal symptoms vasospastic symptoms. There are four well-defined stages of lower limb ischaemia (lack of blood supply) (Table 3. Most patients are asymptomatic, either because they choose not to walk very far, or because their exercise tolerance is limited by other pathology. Tissue loss (ulceration/gangrene) Intermittent claudication is pain felt in the legs on walking due to arterial insufficiency. The pain typically occurs in the calf but may be felt in the thigh and/or buttock if proximal obstruction to blood flow is present. The pain disappears completely within a few minutes of rest but recurs on walking. The claudication distance is how far patients say they can walk before pain starts. Neurogenic claudication is leg pain on walking due to neurological and musculoskeletal disorders of the lumbar spine. Venous claudication is pain due to venous outflow obstruc-tion from the leg following extensive deep vein thrombosis. Neurogenic and venous claudication are much less common than arterial claudication and can be distinguished on history and examination (see Table 3. This occurs typically when the patient goes to bed and falls asleep but is woken 1-2 hours later by severe pain in the foot, usually in the instep. This is because the beneficial effects of gravity on lower limb perfusion are lost on lying down.
However depression test for teens purchase cheap amitriptyline online, as the dis ease persists over time bipolar depression symptoms in children purchase amitriptyline in india, each change in treatment or illness assessment will exacerbate this emotional state depression test free online nhs cheap amitriptyline 50mg line, but with a shorter duration depression elevation definition amitriptyline 10mg with amex. In this way, whatever the case, the period of actively fghting the disease tends to extend over time and creates a huge number of new situations for patients, which require an effort to be assumed and integrated into their daily lives. Once the active treatment process has ended and when the patient remains, at least temporarily, disease-free, the frst reaction observed is satisfaction and joy. However, in this period of time in which patients have to reintegrate themselves in their daily life, they will also face the limitations that the illness and/or its treat ments have caused. This (in addition to the fear of disease recurrence) results in an attitude of hypervigilance and insecurity, which is greatly increased by the coherent spacing over time of medical appointments, with a marked exac erbation of the emotional symptoms as these appointments come nearer. The above-mentioned state is defned as “Damocles syndrome” and alludes to the continuous fear of recurrence of the cancer that underlies the recovery of cancer survivors. This fear involves the awareness of vulnerability and the lack of control over their own lives, which cancer survivors fnd it diffcult to overcome. Moreover, it is also at this time that patients are capable of assessing their own strength, due to having Psychological Complications 265 come through such a traumatic experience and being capable of recover ing from the consequences. The diagnosis of a metastatic process or a relapse awakens the same psy chological processes in the patient as at the frst diagnosis (ffth stage), but the fears and insecurities observed at this point are usually more intense, given that they involve the “failure of previous treatments”, “going through the same thing again” and “if it doesn’t work again”. All of the attitudes and emotions that are included within these patterns of thinking will again threaten the patients’ capacity to adequately deal with their situation. At these times it is very important for profession als to focus on caring for the most subjective aspects, since the patient already knows and is managing many of the objective diffculties that the new treatments will involve. Finally the sixth and last stage, the time at which the patient receives the news that nothing can be done to cure the disease, causes a new process of rupture. The patient has gone from “being a healthy individual” to “an ill patient”, from “an individual who has beaten cancer” to “a patient who is ill again” and, lastly, from “a patient who is fghting against the disease” to “an individual who is going to die from it”. In these dichotomies we can observe how the subject goes from being a “patient”, a person who requires the care and guidance of a professional to live with his/her illness, to an “individual”, a person who must redefne his/her expectations, fears, priorities and values so he/she can adjust to the different moments of his/ her life. As such, in the terminal phase, the individual enters a stage of great existential and philosophical refection that will determine the qual ity with which he/she will face the end of his/her life. The terminal process involves patients in giving answers, closing chapters and giving their life meaning, and therefore if they freeze emotionally and excessively avoid the situation, we must consider that they are adjusting poorly. Technical Procedures Involved the assessment of the symptoms presented by the patient, the moment at which they appear and their duration will be key elements for discern ing whether or not the patient is adapting adequately to the situation or 266 Blanco-Piñero et al. Hence, a mental illness in cancer patients has a series of particular char acteristics that differentiate them from the cancer-free population. As a result of the disease and its treatments, the patient may present a vegeta tive and/or cognitive mood that may be confused with the manifestation of a non-existent psychopathological profle. The confusion that can be created in the evaluation of the psychological and emotional state of the patient leads to two contrasting situations. On one hand, if there is the slightest sign of emotional suffering, the patient could be treated unnecessarily, turning an adaptation process that could be normal into a pathological process. On the other hand, it may be considered that these expressions of emotional suffering are normal reac tions to the situation that the patient is experiencing, and therefore are not to be addressed. Thus, those who really show an abnormal response to their illness might not receive the appropriate treatment. Once the potential vulnerabilities of the patient have been identifed, they can be addressed and potentially managed, both through the sense of security given by the objective care of the illness, and through empa thy for the patient and his/her family group. In this sense, the caregiver must not only have a clear understanding of the adjustment and adaptation processes that must be expected of a patient who is dealing with his/her disease adequately, but also of the potential complications that could arise in these processes, and their repercussions on the patient’s capacity to adhere to the treatments required. In order to carry out the processes of patient evaluation and support, communication skills must be one of the main resources in the oncologist’s arsenal of therapeutic tools. Predictive and Prognosis Markers In Table 1 we aim to identify some risk factors which can predispose patients to present disproportionate or maladjusted responses throughout the disease and its treatments. Psychological Complications 267 Table 1 Vulnerability Factors in Adaptation to Cancer Dimension Vulnerability factors Consequences Social Poor social and/or family support Feeling of loneliness, abandonment, incomprehension, With dependents in their care rejection, anguish, sadness and anxiety Low income Anxiety resulting from a lack of objective resources for meeting obligations and addressing responsibilities Previous experiences of caring for Fears and insecurities linked to these experiences, and patients to the experience of dependence Personal Gender Women usually appear more affected due to diffculties in controlling emotions. In this regard, whether cancer patients experience their illness as an opportunity for personal growth and reaffrmation, or as a devastating experience that could even trigger psychopathological symptoms, will depend, among other factors, on the assessment made by the patients of their personal situation, and on the resources that they have at their disposal in order to face it. This assessment will set in motion the coping processes that will allow them to deal with a potentially fatal disease, whose treatment is usually highly aggressive. Clinical Results Many studies have concluded by linking the symptoms of depression and anxiety with cancer in general and with each moment that can be defned throughout the treatment process. However, and despite the pro fuse literature that can be found in relation to the incidence of psychiatric symptoms in cancer patients, a stable and single incidence value cannot be established: the reported prevalence varies between 18% and 50% of patients. This great variability of data remains when we attempt to deter mine the incidence of more specifc profles such as depression, anxiety, post-traumatic stress or adaptive disorders. This wide disparity of results has various explanations, but the most important is the wide diversity of methodologies used. Whatever the incidence, however, what has to be confrmed (more or less unanimously) is that cancer patients are more vulnerable to psycho logical suffering. The incidence of these symptoms is higher in patients who have physical or functional limitations as a result of cancer or its treatment. Most of the studies consulted focus on very specifc moments in the cancer treatment process. Thus, following diagnosis, an increase in the incidence of anxiety symptoms is observed in patients who adapt poorly at this moment. Once active treatment against the disease is introduced, symptoms of depression are likely to present a higher prevalence. Post traumatic symptoms, if they appear, tend to evolve in parallel with the cancer treatment and recovery processes. Psychological Complications 269 Potential Future Developments Due both to the increase in survival rates, and to the change in attitude that is occurring from within medicine itself, the patient’s quality of life is a necessary measurement to assess the real and multidimensional effectiveness of treatment protocols. Thus, the objective of medical intervention in the treatment of cancer patients must be to pursue patient recovery whenever possible, and to boost the patient’s well-being in all cases. To reach this goal, treating cancer from a holistic perspective is mandatory, with the aim of simulta neously alleviating the physical and psychological suffering. In conclusion, we can consider that the assessment of quality of life becomes one of the best measurements of treatment results, along with survival, in cancer populations. As stated previously, we should under stand that, with regard to the future of oncological intervention, we must integrate into medical training both the knowledge of emotional suffering resulting from the course of the disease and its treatments, and the com munication skills necessary for the detection and support of this distress. Likewise, we consider that the creation of multidisciplinary work teams for treating cancer patients, in which the integral suffering of the patient is addressed in a coordinated and systematic way, is mandatory.

We must recognise and thank the authors for the many hours they have devoted to this work – without them, this update would not have been possible. As this needed to be updated and extended, the Publishing Working Group took over this task. I am very grateful to both of them for the immense work of reading and re-reading the texts, asking the authors to add or correct where it was needed, so that an oeuvre has now been produced which will again be very useful for all European oncologists. I also thank all the young authors and their senior tutors who helped complete the work on time for publication. Professor Michele Ghielmini Chair of the Publishing Working Group 2012–2015 Oncology Institute of Southern Switzerland, Bellinzona, Switzerland xviii I Cardiovascular complications Cardiac Complications of 1 Cancer and Anticancer Treatment G. In addition, several anticancer agents can induce potentially irrevers ible cardiac dysfunction, and the development of targeted therapies has recently widened the cardiotoxic spectrum of antineoplastic drugs. Increasing the chance of survival as a consequence of improvements in cancer diagnosis and treatment highlights the relevance of this topic, since cardiac complications can adversely affect survival and quality of life independently of cancer prognosis. In this chapter, we briefy review the cardiac complications of both neoplastic diseases and cancer treat ments, describing their incidence and aetiology, and focusing on strate gies to evaluate, treat and prevent this wide spectrum of disorders. Malignant Pericardial Effusion and Cardiac Tamponade Aetiology Malignant cardiac involvement is not an infrequent event, its incidence at autopsy being around 10% in patients with known malignancies. In addition, chemotherapy-related effusions are occasionally observed (up to 1%–2% incidence) following exposure to busulfan, cytarabine, cyclophosphamide or tretinoin, especially when these drugs are used at high doses or in combination for the treatment of haematological malignancies. Evaluation As fuid accumulates in the pericardium, the increase in intrapericardial pressure affects diastolic flling of the heart, leading to decreased cardiac output. Symptoms may arise gradually or rapidly, depending on fuid accumulation rate, and may range from dyspnoea, chest pain, cough, pal pitations and orthopnoea, to fatigue, anxiety and confusion. At physical examination, tachycardia, decreased heart sounds, neck vein distension, peripheral oedema and pericardial friction rubs may be present. Pulsus paradoxus, defned as an inspiratory decrease of more than 10 mmHg in systolic pressure, is a rare but suggestive sign of pericardial effusion. However, two-dimensional echocardiography is considered the standard method for diagnosing pericardial effusion. Pericardiocentesis is usually needed to establish aetiology, the malignant nature of pericardial effusion being confrmed by identifcation of malig nant cells at cytological examination. Treatment Treatment depends on the underlying aetiology and symptom progres sion. In patients with minimal symptoms without haemodynamic impli cations, systemic management is warranted, especially in chemosensi tive cancers, and radiotherapy may also be indicated. How ever, immediate pericardiocentesis is mandatory and life-saving for patients with tamponade. If no systemic therapy can control the pericardial effu sion, local measures, such as subxiphoid pericardiostomy, with or without intrapericardial instillation of sclerosing or cytotoxic agents, percutaneous balloon pericardiotomy and pericardial window, may be considered. Type I cardiac dysfunction, typically induced by cytotoxic agents, is due, at least in part, to oxidative stress on the cardiac muscle, resulting in free radical formation and cell death. It is irreversible and typically associated with signifcant ultrastructural changes at biopsy. Cardiac Complications of Cancer and Anticancer Treatment 5 Anthracyclines and cytotoxics with cumulative dose-related cardiotoxicity: type I agents Even if several cytotoxic agents have been associated with cardiac toxic ity (Table 1), anthracycline-induced cardiotoxicity is the most studied, given their frequency of use and resulting morbidity. Acute toxicity occurs during or immediately after infusion, and includes arrhythmias sometimes accom panied by an acute, transient decline in myocardial contractility, which is usually reversible and not dose-dependent. Symptoms usually appear during the frst post-treatment year, but may occur even after 10–20 years. For this reason, a cumulative doxorubicin dose of 450–550 mg/m2 is empirically considered as the highest allowed in clinical practice. Other anthracyclines, such as epirubicin, idarubicin and daunorubicin, induce cardiotoxicity less frequently (0. Moreover, intravenous bolus administration and higher single doses of anthracyclines, concomitant use of cyclophosphamide, taxanes or trastuzumab, and previous mediastinal irradiation can increase the risk of developing cardiac toxicity. Liposomal anthracyclines are gener ally associated with a lower rate of cardiotoxicity compared to standard anthracyclines; for pegylated liposomal doxorubicin, which has been the most extensively studied, clear evidence shows a better cardiac safety profle. However, high cumulative doses of liposomal anthracyclines may still be associated with cardiac damage (Safra 2003). The use of cardioprotectants such as dexrazoxane, which acts by chelat ing iron and decreasing iron-mediated free radical formation, has con frmed effcacy against anthracycline-related cardiac damage. The temporary cardiomyocyte dysfunction caused by trastuzumab is prob ably secondary to inhibition of cardiomyocyte human ErbB2 signalling, thereby interfering with normal growth, repair and survival. Evaluation and Treatment Prevention is the best approach to minimise chemotherapy-induced car diotoxicity. The intro duction of a drug-free interval between anthracyclines and trastuzumab, or the administration of anthracycline-free regimens, can lower the poten tial risk of cardiac damage. Gener ally, in the adjuvant setting, serial monitoring of cardiac function every 3 months has been proposed, while patients treated for metastatic disease can be monitored less frequently in the absence of symptoms. Nevertheless, the standardisation of their use in clinical practice is still under debate. When managing trastuzumab-related cardiotoxicity, “stopping/restart ing” rules are usually effective, and their use is recommended (Figure 1). Arterial Hypertension Hypertension is a relatively common and dose-related side effect of sev eral antiangiogenic drugs (Table 2). It can occur at any time after therapy initiation; however, pre-existing hypertension is an important risk factor for complications. Clinical trials of bevacizumab reported grade 3–4 hypertension in approximately 10% of patients, with rare cases of hypertensive crisis, encephalopathy or intracranial haemorrhage. In trials with antiangio genic multitarget kinase inhibitors, such as sunitinib or sorafenib, the incidence of grade 3–4 hypertension was even higher, and in some rare cases hypertension was associated with reversible posterior leukoen cephalopathy syndrome, a clinical event characterised by headache, sei zures, impaired vision and acute hypertension (Todaro et al, 2013). Several mechanisms have been proposed to explain antiangiogenic induced hypertension, including decreased nitric oxide signalling in the wall of arterioles, increased endothelin-1 production and capillary rar efaction. It should also be considered whether to put on hold, or defnitively discontinue, treatment according to the severity of proteinuria, based on the manufac turer’s recommendations. As hypertension and cancer can frequently coexist in the same patient, patients who are candidates for treatment with antiangiogenic agents should be screened at baseline for hypertension and for existing kidney disease. Anti-hypertensive therapy should be implemented or optimised before starting treatment, to prevent antiangiogenic-induced uncon trolled hypertension and avoid the development of serious complications. Myocardial Ischaemia Aetiology Several antineoplastic agents are associated with an increased risk of coronary artery disease and/or acute coronary syndrome (Table 3). Table 3 Antineoplastic Agents Associated with Myocardial Ischaemia Agent Incidence 5-Fluorouracil 7%–10% Capecitabine 3%–9% Paclitaxel 0. These acute coronary syndromes seem to be related to endothelial dysfunction and vasospasm of coronary arteries.

If patients claim to mood disorder evaluation purchase cheap amitriptyline be taking unlikely combinations or amounts of drugs, confirm this with the last doctor to look after them. A drug addict may claim to be receiving a prescription for benzodiazepines and opioids in the hope of receiving the same from the admitting doctor. The modern term, concordance, means a shared decision between doctor and patient where they arrive at an agreement that respects the wishes and beliefs of the patient. However, this does not provide evidence that the patient has obtained the drugs from the pharmacist or taken them at the correct time. Drug allergies/reactions Always ask if your patient has ever had an allergic reaction to medication. In particular enquire about previous reactions before prescribing an antibiotic, particularly penicillin. Example of a drug history Drug Dose Duration Indication Notes Aspirin 75 mg 5 years Started after daily myocardial infarction Amitriptyline 25 mg at 6 Takes for poor sleep Feels drowsy in night months morning Atenolol 50 mg 5 years Started after Causes cold hands (? Otherwise the patient may receive a substance which precipitates a life-threatening adverse reaction. Some patients require prompting with suggestions about common familial diseases. In these circumstances ask if your patient or any close relative has been adopted. The social history Upbringing Birth injury or complications Early parental attachments and disruptions Schooling, academic achievements or difficulties Further or higher education and training Behaviour problems Home life a Emotional, physical or sexual abuse Experiences of death and illness Interest and attitude of parents Occupation Current and previous (clarify exactly what a job entails) Exposure to hazards. In trouble with the law House Type of home, size, owned or rented Details of home including stairs, toilets, heating, cooking facilities, neighbours Community support Social services involvement. A social history can be expansive, incorporating everything from childhood experiences to coffee intake. It is rarely appropriate to ask an elderly woman with a hip fracture whether she is injecting drugs but it is always necessary to know if she lives alone, has any friends or relatives nearby, what support services she receives and how well suited her house is for someone with poor mobility. There may be an infirm relative at home for whom the patient cares or there may be no one at home to look after the patient because, although she is married, her husband works abroad for 3 weeks out of 4. Occupational history the work people do may have a profound influence on their health. Symptoms which improve over the weekend or during holidays should always suggest an occupational disorder. The incubation period is useful in deciding on the likelihood of an illness (Table 1. As well as the country your patient visited you should ask about the type of accommodation. Sexual history It is not always appropriate to take a full sexual history (see Ch. If they smoke ask what (cigarettes, cigars or pipe); the quantity (number of cigarettes/cigars or amount of pipe tobacco per day) and the duration. Calculating pack years of smoking 20 cigarettes = 1 packet For example, a smoker of 10 cigarettes a day who has smoked for 15 years would have smoked: page 17 page 18 Click to view full size Figure 1. Do this by asking open questions giving permission for them to tell you, and do not appear to judge them. If they still have difficulty answering, ask them: When did you last have a drink? The content of a detailed alcohol history Quantity and type of drink Amount of money spent on alcohol Daily/weekly pattern (especially binge drinking and morning drinking) Usual place of drinking Alone or accompanied Purpose Attitudes to alcohol the first uses standard measures but is inaccurate and often underestimates intake. The second method is based on direct calculation of the alcohol content of drinks. This is more accurate given the range of alcohol strengths in beers, cider and wine, but it is less convenient. If a person drinks one glass of wine per night, the first method would estimate the intake to be 7 units per week. Many bottles of alcohol are now labelled with the number of units per bottle or per standard glass. In anyone it increases the chance of depression and obesity, and impairs cognitive function. The pattern of drinking is important because binge drinking of a large amount of alcohol causes acute intoxication. Difficulty in controlling starting or stopping drinking and in the amount that is drunk. Tolerance, so that increased doses are needed to achieve the effects originally produced by lower doses. This produces tremor, sweating, rapid heart rate, anxiety, insomnia, and occasionally seizures, disorientation or hallucinations (delirium tremens). Early detection of alcohol problems is important because of the health risks to patients and their families (Fig. Do you ever have a drink first thing in the morning to steady you or help a hangover? But remember that about 30% of the adult population in Britain have used illicit drugs (mainly cannabis) at some time. Symptoms associated with drug use should prompt you to ask further questions (Table 1. Experienced clinicians often carry out the systematic inquiry as they talk about the presenting complaint, but this takes practice and knowledge of the conditions you are trying to exclude or diagnose. Follow up any positive response by asking questions to increase or decrease the probability of certain diseases. The patient with palpitation: are there any endocrine symptoms to suggest thyrotoxicosis, or a family history of thyroid disease? How often during the last year have you been unable to remember what happened the night before because you had been drinking? How often during the last year have you failed to do what was normally expected of you because of drinking? In the last year has a relative or friend, or a doctor or other health worker been concerned about your drinking or suggested you cut down? This allows the patient to: correct anything you have misunderstood add anything that may have been forgotten. Clarify any medical or other terms the patient uses so that you both understand what is meant. Mental and behavioural disorders are very common, with a prevalence of about 20% in the adult general population: they account for about 40% of consultations in primary care. However, severe mental disorders pose serious threats to the health and safety of the patient, and sometimes to the well-being of others. Physical and mental disorders often coexist sometimes coincidentally but more often as cause and effect. For example, a severe infection may precipitate delirium (an acute confusional state), while intravenous drug abuse may result in the patient acquiring infections. Consequently the prevalence of mental disorders (particularly organic brain disorders, mood illnesses and substance misuse disorders) is even greater among the physically ill, and affects mortality and morbidity. Because of these considerations all clinicians should be competent at basic psychiatric assessment of a patient. Assessment interviews usually do have to cover background personal and social factors to establish an understanding of how the illness evolved and to guide management, but the focus, as in all history taking, is the presenting problem and its solution for the patient. Additionally, it is helpful to establish whether: the patient knows about and accepts the referral the patient is able to understand and communicate the patient wishes to be seen alone or with somebody else there is an element of danger behavioural disturbance or other impediments to interview are likely. Otherwise, the interview follows conventional procedures: Put the patient at ease. Allow breaks and digressions (within reason) if the patient requires these notably with sensitive topics or when distress emerges. Concentrate on the presenting complaint, using a technique of nested, open questions to explore the key elements. Once the presenting situation is clear, the patient is settled and rapport permits, take greater control of the interview content through focused questioning and greater use of closed questions. Content the content of a psychiatric history is as follows: Reason for referral Presenting complaint(s) History of presenting complaint(s) Family history (including psychiatric disorders specifically) Personal history childhood; education; occupational history; sexual and marital history; children; current social circumstances Past medical/psychiatric history Prescribed medication; other remedies Psychoactive substance use, including alcohol, tobacco and caffeine Forensic history Premorbid personality. Some aspects of psychiatric history taking differ from standard medical interviewing, and merit further consideration. Risk assessment Mental disorders can be associated with danger: classically depression with harm to self, and paranoid states with harm to others.

In this way, ‘leftward’ columns (columns to the left of any specific column) are ‘stronger’ determinants and generally take precedence over others. Although this patient may be placed in a wheelchair (and perhaps seem initially to be at 50%), the score is 30% because he or she would be otherwise totally bed bound due to the disease or complication if it were not for caregivers providing total care including lift/transfer. Sometimes, there are several columns easily placed at one level but one or two which seem better at a higher or lower level. The combination of clinical judgment and ‘leftward precedence’ is used to determine whether 40% or 50% is the more accurate score for that patient. First, it is an excellent communication tool for quickly describing a patient’s current functional level. Second, it may have value in criteria for workload assessment or other measurements and comparisons. Ambulation the items ‘mainly sit/lie,’ ‘mainly in bed,’ and ‘totally bed bound’ are clearly similar. The difference between ‘sit/lie’ and ‘bed’ is proportionate to the amount of time the patient is able to sit up vs need to lie down. By using the adjacent column, the reduction of ambulation is tied to inability to carry out their normal job, work occupation or some hobbies or housework activities. Activity & Extent of disease ‘Some,’ ‘significant,’ and ‘extensive’ disease refer to physical and investigative evidence which shows degrees of progression. For example in breast cancer, a local recurrence would imply ‘some’ disease, one or two metastases in the lung or bone would imply ‘significant’ disease, whereas multiple metastases in lung, bone, liver, brain, hypercalcemia or other major complications would be ‘extensive’ disease. The above extent of disease is also judged in context with the ability to maintain one’s work and hobbies or activities. Decline in activity may mean the person still plays golf but reduces from playing 18 holes to 9 holes, or just a par 3, or to backyard putting. People who enjoy walking will gradually reduce the distance covered, although they may continue trying, sometimes even close to death (eg. Self-Care ‘Occasional assistance’ means that most of the time patients are able to transfer out of bed, walk, wash, toilet and eat by their own means, but that on occasion (perhaps once daily or a few times weekly) they require minor assistance. For example, the person needs help to get to the bathroom but is then able to brush his or her teeth or wash at least hands and face. Food will often need to be cut into edible sizes but the patient is then able to eat of his or her own accord. Depending on the clinical situation, the patient may or may not be able to chew and swallow food once prepared and fed to him or her. Intake Changes in intake are quite obvious with ‘normal intake’ referring to the person’s usual eating habits while healthy. Conscious Level ‘Full consciousness’ implies full alertness and orientation with good cognitive abilities in various domains of thinking, memory, etc. It cannot be altered or used in any way other than as intended and described here.

Green Tea Catechins and Goldenseal: these supplements may affect therapeutic benefts of anti-hypertensive drugs. John’s Wort: these supplements have the potential to interfere with the cytochrome P450 system and therefore affect the metabolism and/or clearance of drugs. Calcium: Thiazide diuretics reduce calcium excretion by the kidneys and may increase risk for hypercalcemia, metabolic alkalosis, and possible renal failure. Melatonin: Melatonin may impair the effcacy of some calcium channel blockers (nifedipine). Ginseng: Ginseng may exacerbate some psychiatric conditions including hysteria, mania, and schizophrenia and thus compromise the therapeutic beneft of antipsychotics. Ginseng may also inhibit some of the drug metabolizing enzymes responsible for clearance of a number of antipsychotic drugs.
