Also order erythromycin 500 mg, the natural history of depression is to remit eventually generic 500mg erythromycin with amex, with 7 out of 10 cases doing so by 72 weeks discount 500mg erythromycin mastercard. Another reason why medication may not be very effective in childhood may be the high comorbidity levels, the latter not being responsive to antidepressant drugs. It is difficult to know if these discrepancies relate to clinical reality (including high non-compliance rates) or to problems inherent to statistical analysis (e. Cognitive therapy may not be as effective in severe as in ‘mild to moderate’ depression. Fristad ea (2009), in study involving children aged 8-12 years old with depression or bipolar disorder, compared the effects of adjunctive multifamily psychoeducational psychotherapy (8 x 90 minute 1353 However, whilst it is often stated that family discord is aetiologically influential in depressed youth, family therapy, at least in research, may add little. The findings of a Dresden (Germany) study by Beesdo ea (2009) of 3,021 community subjects aged 14-24 years at baseline and 21-34 years at third follow-up are shown in the box. Incidence and conversion of mood episodes/disorders in first 3 decades of life (Beesdo ea, 2009) Estimated cumulative incidence at age 33 years = 2. Mood disorders in the elderly Although reported figures vary greatly, about 15% or more of people over age 65 years have significant symptoms of depression, one-fifth or less of these having severe depression. According to Heok and Ho (2008) risk factors include poor health, brain injury, low B12 and folate, and raised plasma homocysteine levels. Depression is a risk factor for cardiovascular disease and for mortality in coronary heart disease. While some authors claim that depression becomes more common with increasing age, it appears that mania does not. Müller-Spahn and Hock (1994) listed the most frequent problems in this vulnerable group as social isolation, loss of important support systems, loss of autonomy due to psychiatric and physical illness and physical disability, inactivity consequent upon retirement, loss of reputation and finances, residence relocation, and severe insomnia. Older people are likely to be taking many different medications, and some of these (e. Depressed patients with heart disease are less likely to adhere to diet, exercise, and prescribed medication. However, in the elderly depressed there is a reduced white matter response to acetazolamide, i. Tiemeier ea, (2004) in a cross-sectional population-based Rotterdam study, found that atherosclerosis and depression are associated in the elderly. The more severe was extra-coronary atherosclerosis the higher was the prevalence of depression. There was a strong relationship of severe coronary and aortic calcifications with depressive disorders. White matter changes predate and are associated with late-life depressive symptoms. The consequences of missing the diagnosis (Müller-Spahn and Hock, 1994) are loss of quality of life, social isolation, increased mortality (suicide), increased vulnerability to certain diseases, admission to a nursing home, and a large financial burden. Depression is common in nursing homes, factors contributing to this being loss of independence and familiar surroundings, reduced contact with family and enjoyed activities, and physical disorders. In an Irish community dwelling sample of people aged 65 years and older Gallagher ea (2009) found that, compared to early-onset depression, among those with depression commencing at age 60 years or more (late onset) there was less likely to be a positive family history of depression, less reporting of prior hospital admission for depression, greater cognitive impairment, less feelings of guilt, and less thoughts that life was not worth living. Nevertheless, the authors could find no distinct profile of depressive symptoms that helped to distinguish early versus late onset cases at an individual level. Saez-Fonseca ea (2007) found that depressive pseudodementia in the elderly may be a harbinger of dementia with most cases having an established dementia 5 years later! A Dutch study of depression in people aged 55 years or more (Licht-Strunk ea, 2009) found a median duration of major depressive episode of 18 months; 35% recovered within a year, 60% within two years, and 68% within three years; and poor outcome was associated baseline depression severity, a family history of depression, and poorer physical functioning (the latter only improved if the patient recovered from depression). Elderly depressives spend significantly longer as in-patients than do their younger counterparts, they take longer to respond to treatment, and relapse is common. This is more likely if the patient is taking diuretic medication or has poor left ventricular function. Generally, before starting any antidepressant in the elderly one should steer clear of any drug that 1368 might exacerbate any underlying medical illness or interact with other prescribed medication. The importance of psychosocial support cannot be underestimated, even when antidepressant drugs are used. Lenze ea (2003) found little effect of co-morbid anxiety on outcome of late- life depression treated with interpersonal psychotherapy. Depression in the workplace 1367 Risk of hyponatraemia and small increase in risk of falls. Recurrent brief depression This is a relatively new innovation that is said to be common and have a relapsing course. One in twelve people may be affected and the risk of deliberate self-harm may be 13% over ten years. Diagnostic criteria include 3 episodes over 3 months, depressive episode lasting less than 2 weeks, and no association with the menstrual cycle. The usual treatments for depression may be given a trial, although it may be relatively unresponsive to antidepressants (Baldwin, 2003) because episodes may be too short. Also of significance are the adequacy and appropriateness of treatment received, and the duration of the illness episode prior to starting therapy. Other conditions In 1882, the French psychiatrist Jules Cotard (1840-89), described patients with what he called délire de négation, the term Cotard’s syndrome being first used by J Seglas in 1897. Associated features include le délire d’énormité or delusion of enormous body size or a delusion that urinating will flood the world, and delusion of immortality. Cotard’s syndrome may be associated with valaciclovir (Halldén ea, 2007) or may complicate Parkinson’s disease. Lycanthropy is the belief that one is transformed into an animal, classically a wolf or werewolf. This non- specific presentation can be associated with ‘hysteria’, bipolar affective disorder, psychotic depression, schizophrenia, or organic brain disorders. Essentially, the criteria are (a) one or more episodes of depressive symptoms that fulfil the duration criterion for major depression but there are fewer symptoms and less impairment, and (b) the following diagnoses are outruled: adjustment disorder with 1370 depressed mood , depressive disorder not otherwise specified, major depressive episode, dysthymia, cyclothymic disorder, periods of normal sadness, uncomplicated bereavement, mood disorder induced by substance/general medical condition, a history of major depressive /mania/mixed episode(s), and depressive symptoms that occur exclusively during schizophrenia or schizophreniform/schizoaffective/delusional/not otherwise specified psychotic disorders. Mania may be precipitated by sleep deprivation in people who are euthymic, depressed, or who have no history of prior mania. The risk of such a switch occurring in predominantly unipolar depressives has been put at <1%. According to Vieta,(2004) quetiapine (for mania) may not be associated with treatment-emergent depression. Current or past substance use in depressed bipolar patients was not associated with longer time to recovery but may have increased risk for switching directly into mania/hypomania/mixed states in an American study. First onset mania in 1377 later life may be associated with increased vascular risk factors and relatively high current serum cholesterol levels. Women are more likely to experience depressive episodes than mania (men experience both phases with equal frequency) and rapid cycling is more common in females. Mania may be induced in vulnerable people by lack of sleep, crossing many time zones during travel, and shift work.
By May 1987 discount 250 mg erythromycin, Bill Rea had been introduced to the Robens Institute and he and Dr Monro were beginning to map out courses in environmental medicine for doctors and postgraduate medical students cheap 250mg erythromycin mastercard. Unknown to either Professor Rea or Dr Monro cheap erythromycin 250mg fast delivery, the management team of the Robens was heavily weighted on the side of the chemical and pharmaceutical companies. By 1987, through a series of networks, both Dr Rea and Dr Monro were becoming known as serious commentators on the ill-health caused by industrial chemicals. McNeilly, showed himself to be very antagonistic to the work of the Breakspear Hospital. From 1987 onwards, Dr Monro received frequent correspondence from Dr McNeilly who made it clear that he did not agree with the treatments offered at her hospital. Dr McNeilly also refused recognition to Dr Ussher, claiming that he was not competent to care for people with allergic illnesses. McNeilly insisted that both these doctors had experience only with geriatric medicine, despite the fact that they were consultants in general medicine. Despite a time-lapse of almost ten years, Dr Monro was beginning to run into the same problems in the pursuit of clinical ecology that William Rea had experienced in America. Chapter Ten Bristol Cancer Help Centre: Waving Goodbye to the Cancer Industry Gently? A legal review of the prosecutorial cases brought by the medical establishment against patients, physicians, nutritional manufacturers and distributors, clearly reveals that the main issue in most of these cases has been the single therapeutic theme of immune enhancement. Natural methods of immune enhancement are an extreme threat to the cancer chemotherapy 1 advocates. The official history is that of an ever expanding bureaucracy, which like cancer itself, grows unchecked. The history of alternatives, on the other hand, is a diverse history of pioneers who have often died unknown except to their patients. Within the canons of alternative cancer care and research, different therapies are often referred to by the names of their practitioners: Max Gerson, Josef Issels, Wilhelm Reich, Dr Carl and Stephanie Simonton, Harry Hoxsey. The histories of such practitioners and their therapies are, on the whole, not public; they have been buried. Each of the practitioners who make up the history of alternative cancer care has been systematically relegated to the criminal margins by a highly competitive medical establishment. Dr Max Gerson became a medical outlaw in Mexico when he found that there was no room in America 3 for his clinic or his ideas. Not only do the deaths from many cancers go on rising in Britain and America, but deaths in Britain for some cancers remain higher than in 3 any other country in the world. The incidence of breast cancer in England, for example, is almost three times as high as that in any other country. Advances made by the cancer research industry, at a cost of millions, over the last fifty years, have at best been minimal and at worst a huge waste of money. The approaches of official and alternative cancer care are at odds with each other. Despite placatory remarks by established physicians, there can in reality be no reconciliation between them. Official cancer research, like all official medical research, is based upon the science of the cell. Alternative cancer treatment is based upon the whole person and their life condition and is most particularly concerned with prevention. Official cancer care uses a limited number of techniques to destroy tumours, either cytotoxic drugs, surgery or radiation and sometimes a combination of all three. For alternative cancer therapy, getting rid of the tumour is only one battle in a war. Most alternative treatment programmes suggest a life programme, which is preventative and often subversive to the modern industrial way of life. Many of the post-war alternative cancer practitioners have believed in an immunological approach to cancer. At the heart of these ideas is the belief that the health and efficiency of the human organism depends upon the health and strength of the immune system. Organically grown produce should be eaten, often raw, and all processed foods, except the most simply processed, avoided. As many non-nutritional chemicals become lodged in the body and are a continual drain on the immune system, their ingestion should be avoided and various regimes adopted to regularly de-toxify the body. The might of the cancer research industry is geared not to the discovery of new ways to treat and care for cancer sufferers but to the discovery and patenting of high technology instruments of diagnosis and new cytotoxic drugs. A A A Penny Brohn is one of the founders of the Bristol Cancer Help Centre: she is also a woman with cancer. The illness has shaped the course of her life and, as in so many other cases, her own suffering led her to go out into the world and help others. The hospitals gave you treatment for your physical illness, but it stopped at that. There were, and still are, a lot of emotional and psychological difficulties involved in having a disease for 6 which there is not a definite cure. It was in Bavaria that she became acquainted with the idea of holistic cancer treatment. Throughout her stay in Bavaria, Penny Brohn was aware of the terrible difficulties Dr Issels had in setting up and maintaining his clinic. Ironically, while Brohn brought back to England new strategies of cancer care which she had learned during her treatment, she returned without the knowledge she would need to fight similar struggles to those Issels was forced to fight in Germany. Lessons about self defence and resistance are the hardest to pass on, and no doubt Josef Issels saw himself first as a healer and not a tutor in medical guerilla warfare. Foreign specialists who visit Rottach Egern and depart full of excitement, suddenly, for no explicable reason, lose 7 enthusiasm and withdraw support. It was then that he began to understand that the emotional, psychological environment and the history of the patient were all important to their illness and particularly their treatment and he began to develop a holistic idea of medicine. In 1951, Issels met Dr Max Gerson and was influenced by his ideas about treating cancer with diet. The clinic was financed by one of his cancer patients, the director of a large shipping line. Especially vociferous against him were the Rockefeller-backed cancer research organisations and the pharmaceutical companies. The attacks upon Gerson, often promoted by industry, concentrated mainly upon his diet therapy. Issels was by this time a specialist in immunology and believed that all treatments should help strengthen the immune system. He exhorted patients to exercise by walking up the mountains which surrounded the clinic. Rather than use pharmaceuticals, Issels treated his patients with homoeopathic and herbal remedies, insisting upon a well-balanced and carefully controlled diet. Like Gerson, Issels believed in the regular detoxification of the system using coffee enemas.

Probably only a minority of these cases resolve on separation only discount erythromycin 250mg overnight delivery, most cases needing antipsychotic drugs buy 250 mg erythromycin amex. Psychotic discount erythromycin 250 mg with mastercard, dominant individual induces pseudo-psychosis in recipient, the latter being submissive and suggestible. Delusions form simultaneously and independently in two people predisposed to develop a true psychosis. Both individuals are truly psychotic, but onset in one precedes that in the other. Doppelganger syndrome consists of the delusion of being followed by an exact duplicate of oneself. A female (or less often a male) believes that an unavailable male secretly loves her but is unable to declare this fact. The term ‘borderline erotomania’ (pathological infatuation) refers to a group whose pursuit of others is pathological but who do not claim to be loved in turn. It consists of delusions of imposed sexual approaches or sexual intercourse at night by an unseen lover, the ‘incubus’. The patient may wash affected parts excessively, use insecticides or caustics (with secondary dermatitis), use needles to extract ‘insects’, or burn clothes. Freyne and Wrigley (1994) described 6 elderly cases and underlying diagnoses: dementia, drug- induced (Sinemet), primary depression, monosymptomatic hypochrondriacal psychosis, and 1199 hypochondriasis. Remission rates are probably the same for typical and atypical antipsychotic drugs. Psychiatrists are more likely to tell a patient that he has schizophrenia if it is recurrent than if it is a first episode, a stance that most likely refers to an awareness of initial diagnostic instability rather than any conspiracy of silence. Obsessive-compulsive symptoms were found to be overrepresented in prodromal (for psychosis: ‘ultra-high risk’) adolescents by Niendam ea. Possible reasons for delayed access to care in rural Egypt include belief in spirit causes, preference for traditional healers, and being female. In the last 2 years, 57% of schizophrenia/schizophreniform cases, 54% of schizoaffective cases, 62% of affective psychosis cases, and 68% of patients with other psychosis reported some paid employment. Perkins ea (2004) found that earlier antipsychotic treatment improves outcome in first episode schizophrenia, but so did good premorbid functioning. The evidence available is entirely correlational and new approaches to research may provide firmer evidence. An association of longer duration of symptoms with poorer outcome is not unique to psychosis in psychiatry. Funding of early intervention teams is controversial in a resource-strapped era,(David, 2004) some authors suggesting that monies are diverted thereby from the care of patients with severe and enduring disorders. Bosanac ea (2010) suggest that there may be no beneficial effects in the long term and that rates of transition to psychosis are too low to justify intervention outside of research settings. Gafoor ea (2010) reported that early intervention in non-affective psychosis gives superior results to those achieved by generic mental health services but that gains achieved tend to be lost when patients are handed back to the generic team, suggesting that improved generic teams might be as good as early intervention teams. Non-compliance with treatment in schizophrenia Major problem Up to 50% of outpatients do not comply with prescribed treatment Some patients are cognitively compromised, challenging the idea of informed consent Reasons given by patients for non-compliance: thinking more clearly (subjectively) when psychotic, side effects (acute dystonia and Parkinsonism common in first-episode cases), feeling better, dissatisfaction with treatment, forgetfulness, lack of transport, financial reasons, failure to improve, employment, confusion over medication, and being out of town 1204 Syrup and depot preparations, and possibly atypical drugs,(Lieberman ea, 2003; Haddad, 2008) increase compliance Patients prescribed depots tend to have less insight than do those on atypical drugs (Mahadun & Marshall, 2008) Sophisticated testing suggests very few acute voluntarily admitted patients understand need for antipsychotic drugs (Paul & Oyebode, 1999) Patients outside hospital have only limited knowledge about their depot medications (Goldbeck ea, 1999) Adherence therapy may not be effective, at least in ordinary clinical settings (Gray ea, 2006) Beta-blockers in high dosage were suggested but have not become popular, results being contradictory. Classical (typical) neuroleptics are said to be less effective for negative symptoms (e. Antipsychotic medication should be continued for at least 6 months in acute cases. Megadosing with neuroleptics was fashionable but more time on more conservative doses may have the desired effect. Similarly, caution has replaced rapid neuroleptisation because of the potential risks of neurological and cardiac adverse effects; anyway, the efficacy of rapid escalation of doses in order to speed up response has not found support from research. Patients who smoke may need higher doses of antipsychotic drug than do non-smokers. Nicotine reduces Parkinsonian side effects, possibly because of nicotine- dependent activation of dopaminergic neurones. There is insufficient evidence to guide clinicians about when or in whom to stop maintenance drug therapy for schizophrenia. McEvoy ea (2006) found clozapine superior to other atypicals in chronic schizophrenic patients who did not respond to one atypical and the same group (Stroup ea, 2006) found that in chronic schizophrenic patients who just stopped taking an atypical that risperidone and olanzapine were more effective than quetiapine and ziprasidone. Use of medication only when symptoms emerge is associated with an increased risk of relapse and admission to hospital. Electroconvulsive therapy is still a useful treatment for some cases of schizophrenia. The meta-analysis of Crossley ea (2010) found that typical and atypical drugs were of similar efficacy but the side-effect profile was different. However, psychoanalytic theory may provide useful insights into the meaning of psychotic behaviour and thinking that, when used judiciously, may be helpful. Cognitive behaviour therapy: In the setting of a non-confrontational, trusting relationship, patients are asked to review symptoms and associated reasoning, to monitor them, to change the focus of attention and to relax, and to modify behaviour. Redevelopment of skills can be aided by industrial and occupational therapy, social therapies, living-skills courses, day care programmes, rehabilitation schemes, community care schemes, and sheltered accommodation that provides support and supervision. Employment at some level, often below their previous level, is essential, be this open or sheltered. Even with optimal rehabilitation, many patients will require continuing attention and care. Schizophrenic patients may improve in an area specifically chosen for treatment, such as one aspect of memory, without benefit generalising to other aspects of the same function. However, one meta-analysis of cognitive remediation and social skills training in schizophrenia found them to have no benefit (Pilling ea, 2002b) and another meta-analysis (McGurk ea, 2007) found moderate improvement in cognitive performance with cognitive remediation. Krabbendam and Jolles (2002) conclude that the jury is still out on cognitive remediation whereas Szöke ea (2008) suggest that practice produces better results than cognitive remediation. Dickinson ea (2010) found that measures of cognitive function improved with computer-assisted cognitive remediation but that such improvement was not reflected in broader neuropsychological or functional outcome measures. Others have suggested that when the high dropout rate from family interventions is taken into account (intention to treat analysis) there is a significant reduction in benefit in terms of relapse prevention. Still others have commented on the lack of effect of behavioural interventions on intrafamilial communications. Priority families for intervention include those with a treatment-compliant schizophrenic relative living with them but who relapses frequently, those in whom disagreements erupt into violence, families who resort to the police, and those making heavy demands on staff. Family intervention strategies (Kane and McGlashan, 1995) Psychoeducation – didactic information about the illness; information about vulnerability to relapse/ role of stress; understand need for treatment to control symptoms* Stress management – enhanced communication (listening skills, clarifying wants/needs, providing positive/negative feedback), problem solving (managing daily problems and discrete but significant stressors, general problem solving skills) Crisis intervention – recognising prodromal signs/symptoms, plans to deal with threatened compliance, active intervention during prodrome or relapse during treatment, and more structured psychosocial programmes *Burns (1999) stated that that psychoeducation adds little where general services are well developed. Prevention of schizophrenia There are good reasons why primary prevention is currently impossible. Early precursors of schizophrenia in childhood are too non-specific and many children who later develop schizophrenia are perfectly normal as children. Olanzapine reduces the positive symptoms of prodromal psychotic states but induces weight gain. Delusions As for hallucinations, delusions of influence might simply derive from a real difficulty in attributing ones own actions to the self. A schizophrenic patient may believe that he is the president of his country whilst residing in gaol for petty theft: this profound lack of awareness of a fundamental 1221 contradiction is called double orientation. Psychoanalysts have interpreted delusions as providing a defence against low self-esteem, although it is difficult to see how a delusion of persecution could fulfil this 1222 role (unless persecution is equated with self-importance ).
Evaluation as to whether a patient has an infection or not should be made against these established systematized criteria purchase 500 mg erythromycin free shipping. They include clinical evidence and laboratory results that are not confined to microbiology discount erythromycin 250 mg overnight delivery, diagnostic tests incorporating radiology and nuclear medicine cheap erythromycin 500mg fast delivery, and further supporting evidence such as response to antibiotics. It can be seen that the imaging of inflammatory processes and infection is a form of tissue characterization by nuclear medicine. This has moved away from the use of more non-specific techniques that react with inflammation, infection, granuloma and tumours, such as the conventional three phase bone 67 18 scan, with Ga-citrate and F-deoxyglucose, towards agents specific to inflam- mation such as radiolabelled white cells or human immune globulin, and to agents specific to a particular disease (Table 5. The labelling is labour intensive and should eventually be replaced by in vivo labelling methods. Furthermore, the rate of appearance of a positive uptake gives some indication of the inflammation activity. On later images, white cell uptake may be seen in the region of the caecum as a non-specific effect and movement of white cells along the bowel is to be expected in inflammatory bowel disease. White cell uptake will also be evident in infective enteritis, in focal lymphadenitis and in appendicitis. It is not possible to distinguish bacterial enteritis from inflammatory enterocolitis. Another key indication is fever and pain following abdominal surgery, in order to identify a subphrenic abscess, pelvic abscess or focal peritonitis. In the spine, destruction of bone marrow may cause a focal defect in a vertebra, instead of a focal increase. In hip prostheses, the extent of the functional marrow may need to be determined by a colloidal scan to demonstrate whether the white cell uptake is due to marrow (physiological) uptake or to true inflammation at the prosthesis. In neonates, the identification of osteomyelitis with white cells may be unreliable. In cases of fracture, either of the stress or traumatic variants, white cell uptake is non-specific. The advantages are the lack of a need to obtain blood, since they can be given by direct intravenous injection, and their selectivity for particular white cells or inflam- matory elements. The disadvantages include a high molecular weight, which may give poor tissue penetration, although fragmentation helps to improve this; a longer blood residence time; high liver and bone marrow uptakes; potential development of human antimouse antibodies (which is, however, much overstated and not a problem for imaging); and a potential alteration of target cell function. Radiopharmaceuticals The preparation of three reagents is outlined in the following sections. Procedure The following procedure should be adopted: (1) Weigh out the following chemicals: —0. On a melolein dressing pack, mark a circle with a diameter equal to that of the inside of the syringe. Shake a bottle of swollen Sephadex G-50 and carefully transfer the Sephadex G-50 to a 30 mL syringe, right to the top. Pool all fractions with a concentration of 1 mg/mL (absorbance of 1 mg/mL IgG = 1. Add 30 mCi of 99mTcO to the IgG 4 vial and allow to incubate at room temperature for 15 min. Cut the strip into two and count each half, the labelled IgG remaining at the origin, while the free 99mTcO will migrate to the solvent 4 front, i. Quality assurance log The following forms should be completed: Material Supplier & log No. Expiry date Quantity IgG ____________________ _______________ ______________ Mercaptoethanol ____________________ _______________ ______________ Sephadex G-50 ____________________ _______________ ______________ 99mTcO ____________________ _______________ ______________ 4 0. Measure the dose in a dose calibrator and place the dose inside a lead syringe shield for injection. The 99mTc-Infecton remains at the origin, while the free 99mTcO 4 moves to the solvent front, i. Quality assurance log The following forms should be completed: Material Supplier & log No. Expiry date Quantity Infecton ___________________ _______________ ______________ Stannous tartrate ___________________ _______________ ______________ 99mTcO ___________________ _______________ ______________ 4 0. Interpretation (a) Interpretation of white cell images Normal white cell images show transient lung uptake, persistent normally increased spleen uptake with some uniform liver uptake and widespread red bone marrow uptake. A poor white cell preparation may show persistent lung uptake and a more equal spleen-to-liver uptake ratio. The thyroid does not need to be blocked, but some thyroid uptake may be seen if there is a delayed injection. White cell uptake will persist during the healing phase of osteomyelitis even when the bacterial infection has been treated successfully. Lack of white cell uptake may occur in chronic inflammation when a more monocytic or lymphocytic infiltration is present or when there has been prolonged antibiotic therapy for resistant infection. Liver uptake may be more marked than spleen uptake and later images may show renal uptake, urinary excretion and gut activity. Infecton is a small highly diffusible molecule that enters sites of inflam- mation non-specifically and leaves progressively as blood level falls through renal clearance. Sites of acute inflammation, such as an active rheumatoid joint, will show initial uptake that may be maintained for the first four hours or fade. A 24 hour image will show fading in a rheumatoid joint or other active inflam- matory arthropathy but there will be persistence of uptake in septic arthritis, since binding to the dividing bacteria persists. A 24 hour image is also helpful in suspected endocarditis, vascular or orthopaedic prosthesis and fracture. One is generally not required when the site of uptake is obvious on the early images or when chest or abdominal infection is suspected. Technetium-99m Infecton is excreted into the bladder, where activity increases with time so that voiding should be undertaken between sets of images. Initial blood pool activity in the liver and spleen decreases in the later images. Occasionally, scrotal activity may be observed in adults as a result of vascu- larity. Biological barriers prevent access of intravenously injected agents, while bacterial flora does not usually divide actively. There is, however, occasional weak biliary excretion with some caecal activity seen after 4 hours. Uptake in the gut after 4 hours is considered as a normal variant in Asians, probably as a result of active ‘normal’ flora. There may be 109 bacteria in 1 mL of infected material, giving a great number of binding sites for ciprofloxacin. The great advantage of 99mTc-Infecton imaging is the lack of normal bone marrow uptake, so that sites of infection in the spine are positive even when a white cell scan reveals a ‘cold’ defect.
