Painful legs purchase robaxin 500 mg with amex, moving toes: Continuous unilateral pedal sinusoidal flexion-extension with ipsilateral leg pain whilst awake generic 500 mg robaxin visa, with continuation during sleep at a reduced intensity, usually associated with peripheral nerve lesions such as in the lumbar roots. Delayed sleep phase syndrome: This circadian rhythm disorder may affect up to 10% of insomniacs attending sleep disorders clinics. The patient cannot get to sleep until after everyone else and, if allowed, sleeps on that much later. Bright light exposure in the morning and light restriction in the evening may help. Where sleep phase is advanced (advanced sleep phase syndrome) treatment is by evening exposure to 460 bright light. The irregular sleep-wake type of circadian rhythm sleep disorder was described in physically sick people who spent years in bed and were socially isolated. However, it is more likely to be seen in association with intellectual disability, brain damage, and dementia. There is an absence of any pattern to sleeping and waking, patients sleeping for a few hours at irregular intervals. The therapist ‘blames’ the mood disturbance and not the patient for the latter’s dysfunction and suggests that (as well as psychosocial stress) predisposed people may be made more vulnerable to mood disorders by disruptions in circadian rhythm. The ‘social rhythm metric’ is a paper record of daily activities and help needed in doing things chronicxled by the patient. The therapist recommends very gradual re-scheduling of activities such as time of going to bed, e. In: Sleep and Biological Rhythms: Basic Mechanisms and Applications to Psychiatry. Perception is the active, automatic process whereby patterns of sensory stimuli are changed by the nervous system into a conscious experience. Knowledge and experience are then brought into play in order to bring meaning to what is experienced. The brain maintains perceptual constancy by combining what is 463 experienced via the senses with previous knowledge. However, our interpretations of what we experience via the senses is open to bias from preconceived ways of thinking and classifying (schemata). Figure-ground differentiation is a classic example of how the same sensory data can be interpreted differently depending on what part of an image one chooses to emphasise: the famous (central) chalice/goblet and (peripheral) faces (looking at one another) that adorn so many psychology texts. Lower cognitive ability measured on enlistment into military service at mean age 20. Prescribing for the pregnant and nursing mother is discussed here for convenience. When reading North American literature, the reader should be aware of spelling (e. Trade names may differ entirely or by as little as one letter from one country to another. Intelligence tests 465 Tests used should correlate strongly with overall intellectual function or involve batteries that 466 specifically assess intelligence. Problems based on a particular population that was used originally to standardise the test, e. Cholesterol is needed for normal development of the embryo and is part of the structure of cell membranes and is found in myelin. It is also important in the synthesis of some hormones and gastrointestinal acids. Syndactyly and, less often, polydactyly may be found, as may anomalies of various internal organs. Parents accept and admire their babies which allow infants to begin to develop a sense of self- value. If youngsters are required to perform tasks that are outside their capabilities they will fail at the task, will not receive positive feedback and self-esteem suffers. Paternal influences on the psychosocial development of children may have been relatively neglected by researchers. Most paternal psychiatric disorders increase the risk for behavioural and emotional problems in their offspring, probably to a similar degree to that stemming from such disorders in the mother. There is some indications that sons may be more adversely affected than daughters and that behaviour may be more disturbed than emotions. Of course, paternal effects are modified by other variables such as child factors (age, sex, and temperament), maternal parenting and psychopathology, degree of paternal presence, and economics. Jean Piaget (see box), described four stages of cognitive development in children: sensorimotor (so-called because sensory impressions are closely linked with motor activity – starts with reflex gaze and grasp in newborn and ends with at attempts at thinking about a problem at up to two years), preoperational (symbolism to meticulated representational regulation at 8 years), concrete (from classification to simultaneity at 9-11 years – concreteness is well illustrated by asking a child to relate a joke: limited grasp of nuances impairs the ability to do so), and abstract reasoning (hypothetical deductive logic, etc). Piaget’s developmental stages Sensorimotor – 0-2 years – information received via senses and motor activity – no reflective or conceptual thinking – knows an object as something that can be manipulated in certain ways Preoperational – 2-6 years – devilment of symbolism (including language) – one object can stand for another object – egocentric (chiefly sees matters from own viewpoint and assumes others feel and thinks in the same way as does the self) – can only consider one dimension (e. At first everything is black or white, wrong or right, and rules are not to be questioned. Later on the child understands that strict adherence to a rule might have adverse consequences. Memory involves registration (storage is not guaranteed), storage (retrieval is not guaranteed) and retrieval (possible only if information has been stored). Psychologists divide memory into sensory (lasts little longer than the stimulus producing it), short-term (a small number, averaging 7, pieces of information, held for up to half a minute), working memory (more complicated than short-term memory and is required for the carrying out of complex cognitive work), and long-term memory (potentially limitless information held for increased risk of adult mania. Semantic memory involves information such as ones first language whereas episodic memory is concerned with personal data. We may recognise a correct answer from a list of possible solutions without being able to generate it in the absence of the list. Relearning what has apparently been forgotten usually takes less time than was the case at the first attempt. Redintegration refers to the 472 triggering of memory traces when one hears a certain sound or experiences a particular smell. Theoretically, stored information may be unavailable because of so-called passive decay (chemical or structural changes), distortion of information, or interference (two similar stored items create confusion). It has important interconnections with the striatum, thalamus, and the medial temporal lobe, so that lesions in these areas (e. It consists of an articulatory/phonological loop that holds data in mind by using sub-vocal speech, a visuo-spatial scratch pad that maintains data as visual images, and a central executive that directs ‘slave systems’ such as the visuo-spatial scratch pad (the inner eye) and the articulatory (phonological) loop (‘inner voice). The present Halstead Impairment Index, a global measure of brain dysfunction, looks at abstract reason (Category Test), a Tactual Performance Test (blindfolded patient places blocks into holes in a board), fine motor speed (Finger Tapping Test), ability to distinguish musical rhythms (Rhythm Test), and a Speech Sounds Perception Test (after hearing nonsense words on an audiotape the patient underlines printed response on answer sheet). Motivated behaviour, by definition, has a purpose and is directed at a specific goal. It has been ‘explained’ by theorists varying from the humanists who write about self-actualisation to the psychoanalysts (unconscious drives), behaviourists (learning/reinforcement), cognitive theorists, and neurophysiologists. Secondary drives are those that are said not to satisfy a physiological need; play is often given as an example of a secondary drive but play teaches the animal many skills that may be necessary for efficient functioning and hence survival. Behaviour is in fact much more complicated than any of our attempts to explain it.

Speciﬁc autoimmune diseases order robaxin overnight delivery, such as those listed above buy robaxin 500mg overnight delivery, are probably not caused by any general failure of clonal deletion or clonal anergy cheap robaxin amex. Most self-antigen is presented with insufﬁcient avidity to induce either clonal deletion or lymphocyte activation. Humans make at least 105 proteins (average size: 300 amino acids), which can be processed to gen- erate 3 × 107 distinct peptides for presentation to T-cells. Depletion of cells, with this phenotype, from normal mice or from normal cells given to athymic mice, results in the development of autoimmune disease. These sites, which include the brain, testis, eye and uterus (the foetus can be considered an unusually successful allograft), do not elicit immune rejec- tion. Cells and proteins do leave these sites and circulate in the body, although they do not travel in the lymphatics. Tissues in these sites also express Fas ligand; binding of Fas ligand with its receptor induces apoptosis, killing any effector (Fas+) T-cells which enter. In sympa- thetic opthalmia, damage to one eye can on rare occasions result in an autoimmune response to eye proteins that can damage the uninjured eye. When trauma or other events cause damage to the barriers which protect such special sites, this can lead to the release of novel autoantigens and the production of autoantibodies. This provides T-cell help, through linked recognition, for antibody production which need not be (and usually is not) directed against the neoantigen. During an inﬂammatory response an immunostimulatory environment is cre- ated by the release of cytokines which recruit and activate professional antigen-presenting cells and provide support for T-cell activation, rather than anergy. As a result, autoreactive T-cells which were anergic or ignorant might become activated. This is a rather specialised version of the above in which an epitope of an invading microorganism cross-reacts with a self-protein. The T-cell help provided by the other microbial antigens permits the activation of B-cells which make a cross-reactive antibody, which either escapes tolerance or acquires sufﬁcient self-reactivity through somatic mutation and selection driven by the cross-reactive antigen. The classic example is rheumatic fever following infection with Streptococcus pyogenes; antibodies to Streptococcal antigen binds host heart tissue and can damage it. The response is usually transient, since the T-cells are speciﬁc for the Streptococcal antigen and not for self. Human studies are currently underway to investigate a possible link between coronary artery disease and infection with Chlamydia pneumoniae. Spontaneous human autoimmunity seems to be almost entirely restricted to the autoantibody responses produced by B-lymphocytes. Loss of tolerance by T-cells has been extremely hard to demonstrate, and where there is evidence for an abnormal T-cell response it is usually not to the antigen recognised by the autoantibody. This disparity has led to the idea that human autoimmune disease is in most cases (with probable exceptions including type I diabetes) based on a loss of B-cell tolerance, which makes use of normal T-cell responses to foreign antigens in a variety of aberrant ways. Non-immunological therapies, such as hormone replacement in Hashimoto’s thyroiditis, treat the outcomes of the autoaggressive response. The levels of autoantibodies are measured to determine the progress of the disease. It is an artiﬁcial antibody, originally developed in mice; because humans have immune reactions to mouse proteins, it was later developed into a human (humanised) antibody. As a combination of mouse and human antibody, it is called a chimeric monoclonal anti- body (the Fc is human-derived, the Fab mouse-derived). It is administered by intravenous injection, typically at six- to eight-week intervals. Focus on: type I hypersensitivity – anaphylaxis ‘Hypersensitivity’ (hypersensitivity reaction) refers to undesirable reactions produced by the normal immune system (Table 15. Instead of binding to cell-surface components, the antibodies recognise and bind to the cell-surface receptors, which either prevents the intended ligands binding with the receptor, or mimics the effects of the ligand, thus impairing cell signalling. The difference between a normal immune response and a type I hypersensitive response is that in the latter, plasma cells secrete IgE. This class of antibody binds to Fc receptors on the surface of tissue mast cells and blood basophils. Later exposure to the same allergen cross-links the bound IgE on sensitised cells, resulting in degranulation and the secretion of pharmacologically active mediators such as histamine, leukotrienes and prostaglandins. The principal effects of these products are vasodilation and smooth-muscle contraction (Table 15. Treatment usually involves intramuscular injection of adrenaline (epinephrine), antihistamines and corticosteroids. The FcεR1 is a tetrameric receptor composed of a single α-chain, responsible for binding the IgE, a single β-chain and a disulﬁde-linked homodimer of γ -chains that initiates the cell signal pathway. Once the FcεR1s are aggregated by the cross-linking process, phosphoryla- tion of motifs in both the β-andγ -chains initiates a cell-signalling cascade, acting on scaffold proteins of the cytoskeleton to promote degranulation (exocytosis) of the mast cell. Anaphylactic shock, the most severe type of anaphylaxis, occurs when an allergic response triggers a quick release from mast cells of large quantities of immunological medi- ators (histamines, prostaglandins, leukotrienes), leading to systemic vasodilation (associated with a sudden drop in blood pressure) and bronchoconstriction (difﬁculty in breathing). An estimated 1–17% of the population of the United States is considered ‘at risk’ for having an anaphylactic reaction if exposed to one or more allergens, especially penicillin and insect stings. Most affected individuals successfully avoid such allergens and will never experience anaphylaxis. The most common presentation includes sudden cardiovascular collapse (88% of reported cases of severe anaphylaxis). After an initial exposure (‘sensitising dose’) to a substance such as bee sting toxin, the immune system becomes sensitised to that allergen. Common causes include insect bites, food allergies (peanuts, brazil and hazelnuts are the most common) and drug allergies. Symptoms of anaphylaxis are related to the action of IgE and other anaphylatox- ins, which act to release histamine and other mediators from mast cells (degranulation; Figure 15. In addition to other effects, histamine induces vasodilation of arterioles and constriction of bronchioles in the lungs (a bronchospasm). Constriction of the airways results in wheezing and difﬁculty in breathing; gastrointestinal symptoms include abdom- inal pain, cramps, vomiting and diarrhoea. Histamine causes the blood vessels to dilate (lowering blood pressure) and ﬂuid to leak from the bloodstream into the tissues (lowering blood volume). Primary (emergency) treatment for anaphylaxis is administration of adrenaline (epinephrine). Adrenaline prevents worsening of the airway constriction, and stimulates the heart to continue beating. Adrenaline (epinephrine) acts on β-2 adrenergic receptors in the lung as a powerful bronchodilator (opening the airways), relieving allergic or histamine-induced acute asthmatic attack or anaphylaxis. Acute-phase proteins are a class of proteins whose plasma concentrations increase (positive acute-phase proteins) or decrease (negative acute-phase proteins) in response to inﬂammation. The liver responds by producing a large number of acute-phase reactants or reducing the production of others. Cachexia is loss of weight, muscle atrophy, fatigue, weakness and signiﬁcant loss of appetite. Related syndromes are kwashiorkor and marasmus, although these are most often symptomatic of severe malnutrition. After the virus has infected the cell, two outcomes are possible; either the virus becomes latent and the infected cell continues to function, or the virus becomes active and replicates, and a large number of virus particles are liberated, which can then infect other cells.
En- lightened self-interest features prominently in the South African ap- peal: 152 William Bromwich (31) You could be next It’s not a nice thing to consider purchase 500 mg robaxin otc, but the fact is that you best robaxin 500mg, a close friend robaxin 500 mg overnight delivery, or a family member could well be the next car accident victim or surgery candidate requiring a transfusion. Unlike blood donated to the Red Cross or the Armed Services, it is not allocated to a national blood bank: (32) Giving Blood Saves Lives Your donation will help ensure an adequate supply for both children and adults who are patients within Lee Memorial Health System. Here the line between donors and recipients is blurred: they are no longer conceptualised as separate categories but as a fuzzy set (Lakoff 1987: 22), since donors may themselves need donations in the future. This brings to mind Malinowski’s (1922: 167) observation about gifts and counter-gifts in the Western Pacific as “one of the main instruments of social organisation […] and the bonds of kinship”. Self-interest It was initially expected that the institutional discourse would focus entirely on an appeal to altruism but this expectation was not con- firmed by the data. The following list of reasons to give blood begins with the offer of free juice and cookies, and conti- nues with other supposed benefits such as the chance to lose weight and to be excused from heavy lifting, before reaching the point where the donor is placed “on an equal footing with the rich and famous”. Paradoxically, an act that seems to be emblematic of altruism is moti- vated by a long list of self-centred considerations: (35) Top 10 Reasons to Give Blood The American Red Cross is constantly encouraging people to donate blood. It’s easy and convenient – it only takes about an hour and you can make the donation at a donor center, or at one of the many Red Cross mobile blood drives. The same line of reasoning appears on the Knoji Blood Donation web- site: (36) Donating Blood Is Healthy From a health standpoint, I can’t think of a better way for people with high blood pressure, migraines, or high cholesterol to let go of some waste. I do it to help with my blood pressure and migraines, as unloading two pints of blood [sic] is the best way for me to relieve pressure in my brain and my body. According to studies published in the American Journal of Epidemiology, blood donors are 88% less likely to The Gift Relationship: Cultural Variation in Blood Donor Discourse 155 suffer a heart attack. Urging people to donate blood more often, Harsh Vardhan said: “Regular blood donors, according to medical researchers, are 80 per cent less prone to diseases like heart attack, cancer, etc. Strands of argumentation in the discourse In each of the institutional appeals an attempt was made to identify the predominant strand of argumentation and the results are set out in the following matrix diagram. Although the discourse of altruism (upper left-hand quadrant) is predominant, the discourse of self-interest (up- per right-hand quadrant) also plays a significant role, and enlightened self-interest (lower left-hand quadrant) is also well represented, along with a strand focusing on organisational, scientific and technical is- sues (lower right-hand quadrant). Whereas in the institutional discourse there was a focus on altruism as the main motivation for blood donors, with some atten- tion to enlightened self-interest and organisational, scientific and tech- nical information, in the media reports the focus was primarily on self- interest, mainly considering the health benefits for the donor rather than the recipient. Concluding remarks This study investigated aspects of argumentation in the institutional blood donor discourse of a number of English-speaking countries and states, examining the strands of discourse based on altruism, en- lightened self-interest and self-interest. Institutional and cultural varia- tions were identified, not simply reflecting different national contexts, as in some instances cultural variation was identified also within the same national context. A stark contrast was evident between on the The Gift Relationship: Cultural Variation in Blood Donor Discourse 157 one hand the discourse of the institutional actors, in which altruism tends to prevail, along with elements of enlightened self-interest, and on the other hand the media reports, where self-interest clearly predo- minates. Healthcare professionals seeking to identify a judicious mix between the various motives to persuade blood donors to come forward to become regular donors might wish to compare their discursive practices with those characteristic of media reports as some mutual learning appears to be possible. Regardless of the specific approaches in the various national contexts, it is evident that public health information professionals need to continue to pay close attention to blood donor issues, also exploring the possibilities 3 afforded by social media. To conclude, the ongoing need for effective public health information is evident in this quotation from the Yelp review by a San Diego blood donor who was ‘weirded out’ not by the needles or the blood, but by the ignorance of potential donors: (40) I gave blood on one of their busses today. Introduction In the last two decades, Applied Linguistics and Translation Studies can be said to have experienced a similar shift: both disciplines have increasingly extended their focus of attention on social questions. It is true that the purpose of Applied Linguistics has always been “to solve or at least ameliorate social problems involving language” (Davies 1999: 1): but it is especially with the relatively new branch of Critical Applied Linguistics that issues such as identity, sexuality and power have become central questions to be addressed (Pennycook 2004: 785). Similarly, also Translation Studies have been more and more concerned with social factors involved in translation, with the translator’s social responsibility and issues of translation ethics (see for instance Pym 2006, Baker/Maier 2011). The ‘ethics of difference’ (Venuti 1998) has become a fundamental concept which has opened up many new lines of enquiry and has also influenced the authors of the present chapter. Being particularly interested in matters concerning human rights and vulnerable subjects, we have recently started to investigate communication to disabled people in three languages, i. While in the past, society only recognized the binary distinction between two sexes, it is now gradually accepting the variety that exists in real life. Moreover, this is one of the cases where language does not only express or reflect one’s identity as a particular kind of social subject, but also contributes to constitute it (Pennycook 2004: 393). Against this background, translators, language experts, and other professional communicators may play a fundamental role in identifying and helping to spread the best linguistic and communicative practices. In the field of medical translation and interpreting, the ethical question has been highlighted, among other authors, by Montalt-Resurrecció/González Davies (2007) and by Angelelli (2004), who wrote the first study on the role of medical interpreters in hospital settings. In particular, we share the view of Montalt-Resurrecció and González Davies (2007: 22- 23) that one of the ethical priorities of the medical translator should be to promote understanding, respect and empathy towards specific groups of patients, and towards different cultural views on health. But first of all, a look will be taken at some basic concepts and their respective designations in the three languages of this study, Italian, German and Dutch. The starting point will be English terminology, as many of the reference works, guidelines and other documents have originated in English-speaking countries or are written in English. Here, reference will be made to the definitions contained in the guidelines of the American Psychological Association (2011): Sex refers to a person’s biological status and is typically categorized as male, female, or intersex (i. Gender expression refers to the ‘way in which a person acts to communicate gender within a given culture; for example, in terms of clothing, communica- tion patterns and interests. Categories of sexual orientation typically have included attraction to members of one’s own sex (gay men or lesbians), attraction to members of the other sex (heterosexuals), and attraction to members of both sexes (bisexuals). English and Italian thus seem to show a significant terminological overlap: the only remarkable difference concerns the rendering of the concept of gender expression with ruolo di genere in Italian, which is defined as “tutto ciò che una persona fa o dice per indicare agli altri e a se stesso la propria connotazione sessuale: il grado della propria femminilità, 166 Mariella Magris / Dolores Ross 1 mascolinità o ambivalenza”, and which is used much more frequently than espressione di genere. This distinction is only gradually gaining ground in Italy; for the time being, ruolo di genere is generally used with the above-mentioned meaning, and not as a direct equivalent of gender role. In German, there are not two different words to distinguish between sex and gender: Geschlecht is widely used to express both concepts, al- though the loan word Gender has been introduced to designate the so- cial aspect. In the compound nouns referring to identity and role, both elements – Geschlecht and Gender – are used, with the more ‘ambi- guous’ terms, Geschlechtsidentität and Geschlechtsrolle, being much more widespread than the more precise hybrid forms Genderidentität and Genderrolle. Dutch uses the words sekse or geslacht to refer to the biological differences between man and woman and, more recently, the loan word gender to refer to the social, psychological and cultural aspects related to being man or woman. Therefore, as in German, the distinction between the two concepts becomes sometimes blurred in compound nouns, where geslacht is used to express not only the biological sex, as in geslachtshormonen and geslachtsaanpassende behandeling, but also the cultural and psychological aspects, as in geslachtsidentiteit. Gender Dysphoria 167 At any rate, the importance of the concept of gender in the Netherlands is also demonstrated by the replacement, in the Nineties, of most academic vrouwenstudies (women’s studies) by gender studies. Finally, like German, Dutch has the term genus, but this is not really a viable alternative, as it is usually restricted to its grammatical or biological sense. Genderrol and the less common geslachtsrol are the equivalents of gender expression, whereas seksuele geaardheid and – less frequently – seksuele oriëntatie designate the concept of sexual orientation. Here we will focus on the cases when one’s gender identity and biological sex are not congruent, and we will refer to these situations of ‘mis- th match’ as gender dysphoria. However, as the members of the Sexual and Gender Identity Disorders Work Group of the manual have pointed out, removing the condition as a psychiatric diagnosis altogether could jeopardize access to treatment (see Lescher 2013): the diagnosis is necessary for affected people to claim coverage for surgery, counseling and other treatments on their private or public health cover. First of all, it is not a new word: as a matter of fact, it was introduced in 1973 by Norman Fisk and is now considered 168 Mariella Magris / Dolores Ross ‘obsolete’ by some authors (Motmans et al.

In general, Grave’s patients get treated with between 10-20 mci if their uptake is significantly elevated. Multinodular goiter patients typically get treated with > than 20 mci (but less than 29. It should be noted that the vast majority of patients will be on synthroid within 6 months to one year after therapy. Older patients, multinodular goiter patients, younger patients, and autonomously functioning nodule patients all have increased rates of retreatment. A signed requisition must be approved by the nuclear medicine physician before isotope is ordered. All females in child bearing age (11-60 years old) scheduled for I-131 thyroid therapy: 1. Document pregnancy test results (or tubal ligation/hysterectomy/menopause) on the thyroid information sheet c. Check that the patient has not been on thyroid medication or had contrast studies for the past 6 weeks. Make the patient aware that I is eliminated by the saliva, sweat glands, and kidneys, and that his/her urine will be radioactive for a few days. Advise the patient to avoid close contact with small children for a few days, and to discontinue breastfeeding. Clear liquids only for 4 hours before and one hour after radioiodine administration. If the technologists is unable to answer any questions the patient may have, contact the radiologist to do so. A copy of the prescription should be available at the time the dose is administered, and 2. Some radioactive iodine is excreted in your urine, and a little is excreted in your saliva and perspiration, requiring some precautions to avoid spreading any significant radiation to by-standers. Most patients experience no side effects from this treatment, and only one in ten to one in twenty require a second treatment. After thyroid function becomes normal, nearly all patients will later go on to develop an underactive thyroid, requiring life-long thyroid hormone pills for replacement; your physician will check for this periodically. If any tenderness of the gland develops in the week after treatment, aspirin, ibuprofen or Tylenol will usually provide sufficient relief; if not, call your physician. Food and Fluids: It is preferable to not eat for four hours before and for one hour after radioiodine treatment to enhance absorption from your stomach. Following therapy, drink at least 2 quarts of liquids (8 glasses) per day for the first three days to hasten excretion of the radioiodine. Time and Distance: For two days, you should minimize the length of time in contact with others and try to maintain a prudent distance from them in order to reduce their exposure to your radioactivity. Sleep in a separate bed (at least 6 feet separation) for the first two (2) days after your treatment. Remain at least six (6) feet away from children and pregnant women for two (2) days. Do not nap with children or hold an infant or child for more than several minutes (<30 min/day) for 14 days.. Radioiodine is secreted into the breast milk and can damage the infant’s or child’s thyroid gland. Have the sole use of a bathroom; if not possible, wipe the seat of the toilet after each use. If you have plans to use commercial transportation over the next several weeks, you may need to present this note. If you have any questions or concerns after therapy, please contact Huntsville Hospital’s Radiologist and ask to speak with the Radiologist in Nuclear Medicine. Follow-up: It is important that you see your physician within the first 4-8 weeks after treatment and regularly thereafter in order to evaluate your response to your radioiodine therapy. The accumulation of Tl in a parathyroid adenoma is non-specific and is most likely related to the cellularity and/or vascularity of the lesion. The double-phase sestamibi study is based on the time dependence of localization within the thyroid and parathyroid tissue. An initial image represents the "thyroid phase" and is used mainly as an anatomical reference for the delayed image. Over time, there is decreased uptake in the thyroid gland and persistent uptake in parathyroid adenomas.
