Secondly medications overactive bladder order cytoxan master card, the mapping utilized a hydro-vacuum to schedule 8 medications list purchase generic cytoxan remove the topsoil medications given im cytoxan 50 mg for sale, by the 1991-1992 crews plotted an assortment of cutting through the overburden atop the cemetery to medications and mothers milk order cytoxan 50 mg overnight delivery buried utilities and steam tunnels. During the A variety of recent historic disturbances were removal process, it became evident that this line was encountered during the course of investigations. Milwaukee County personnel wished to water main in this vicinity would place it within a keep this water main active as long as possible as the few feet of any burials that remain intact just under line fed several adjacent fire hydrants and buildings Doyne Avenue. Mortenson Company necessitated the maintenance of a roughly five foot project leaders (in conjunction with Milwaukee buffer on either side of the water main, restricting County) opted to relocate the water main south of access to numerous burials in the central portion Doyne Avenue, well outside the projected bounds of of the project area. These lines consisted of electoral conduit encased in concrete which ranged from two to three feet in width, and roughly one and a half feet in height. The lines crossed the cemetery area in a northeast-to-southwest path, with the southernmost conduit line turning abruptly east-west just north of Doyne Avenue (see figure 4. In the eastern portion of the excavation area these concrete works were a few feet above the elevation at which coffins were being identified, thus the original installation of these utilities did not disturb any burials in this portion of the cemetery. However, in the very southwest corner of the 2013 excavation area, the southernmost electrical conduit line was installed at an elevation that coincided with the depth of several coffins. As excavations moved east, it was clear this conduit line had displaced and disturbed several coffins when it was installed; as visible by the poor condition of several grave lots in its path. Mortenson Company personnel, the concrete berm was cut with a handsaw into several smaller pieces to minimize any additional damage to Figure 4. Working around the water main (top); the graves during removal of the concrete segments. The trench in which Site Boundaries: Then and Now actual water main was set measured approximately 4. This resulted in the site files the site area listed (as of October 2015) the recovery of several isolated fragments as well as is 69, 975. The first estimate (designated Estimate A in figure Utilizing their identified boundaries and the limits 4. Fragmentary human remains were encountered If the entirety of Estimate A were only juvenile/ during the course of the work. Historic newspaper Estimate B are included, those numbers reach up to accounts noted that it was not uncommon for some 1, 165 if all were juvenile burials and 500 if all were of the fill removed from the cemetery area during the adult. Thus, a conservative estimate for the number construction of the former nurses’ residence in the of intact burials that remain, primarily under Doyne 1930s to be disbursed across the adjacent landscape Avenue ranges from 382 to 1, 165 individual graves. There are several things to consider when Cemetery Organization and Land Use looking at the distribution of interments. Area I is the largest area, the earliest marked on the map) and places the total area of utilized, and is comprised of distinctly demarcated this cemetery as 3. This may were disturbed prior to the 1991-1992 archaeological very likely be the result of the vagaries of mapping investigations. The number of coffin burials represented by the 1991, 1992 and 2013 excavations is 2, 281. Area I remains the earliest of this juvenile cemetery area mimics the larger used portion of the cemetery. Based on both the 1991-1992 and first western expansion of adults from the original 2013 excavations this area is spatially distinct from cemetery boundaries. Again, handle distributions suggests rapid field examinations of soils and sediments as it may have been utilized a little later in time. Individuals of heavy metals or toxic compounds (Radu and were buried from west-to-east in one row of burials Diamond 2009). Street Cemetery (Lillie and Mack 2015) also noted the presence of bluish soils but considered the coloration the orderly layout as well as the realization that this the result of particular kinds of molds. However, at section may have more individuals that have been in this case, the immediate area was cordoned off and anatomized and not listed in the Register makes excavation of the associated burial was halted until the layout of rows difficult to discern. A computer controlled the instrument and three readings of 180-second duration were recorded for each artifact. The instrument was operated at settings of 40Kv and 30 micro-amps with Bruker’s “green” beam filter (6 mil Cu/1 mil Ti/12 mil Al) installed. It should be noted that the four soil samples analyzed were coffin fill collected from the pelvic region of burials. Consequently, arsenic levels in these deposits may not be typical of undisturbed cemetery soils. Dentures were analyzed in the laboratory as an aid to preliminary artifact analysis. Late nineteenth century and early twentieth century dentures were manufactured from a compound patented as Vulcanite by Charles Goodyear. Goodyear Dental Vulcanite Company (the same firm still manufacturing tires) chose to no longer enforce Subsequent comparisons to adjacent soils as well as its patent, dentures became commonly available soils from other parts of the cemetery suggests that at affordable prices (Wynbrant 2000). The 2013 low levels of arsenic are typical of many locations in specimens appear to be typical examples of Vulcanite the cemetery but the 10569 deposit did not appear to dentures with an elemental composition including have spread too far from its point of origin (Figure high relative levels of sulfur.

With the lack of formal organization or material culture careful observation of the stratigraphic sequence, suggests that this assemblage represents a secondary the remains were excavated, photographed, and burial. This was complicated somewhat by Farm lists three earlier entries when bones were taphonomic processes which had settled the bones removed from graves for reburial in another location in different directions, causing them to interlock on the grounds, and Lot 10088 may represent a and requiring the full excavation of large sections of similar relocation of remains. Burial Lot: 10508 Several long bones of the uppermost layer had been One of the most unusual burial features encountered pressure-fractured from activity on the overlying during the 2013 investigations was that of a canine in soil, which also compressed the remains in lower a human coffin. The canine the dog’s limb measurements are slightly smaller was interred in a coffin clearly designed and built than those typical of Malamutes and are much for a human (Figure 4. The canine’s head was larger than a coyote’s average limb measurements oriented to the east, placed at the foot end of the (Crockford 2009) (see Appendix G). Like several other burials recovered from the cemetery, shifting of the skeleton In 1913, Louis M.

Some of these include: poor respira tory function ok05 0005 medications and flying order cytoxan mastercard, upper airway obstruction medications via g-tube cheap cytoxan 50mg on line, a tight tting or too large trache tube symptoms 3 days after embryo transfer cytoxan 50mg online, or vocal fold dysfunction medicine in ukraine purchase cytoxan mastercard. During cuff de ation trials the speech pathologist may also wish to see how the patient copes with temporary occlusion of the trache so that the normal pattern of breathing, swallowing and speaking is temporarily resumed. The speech pathologist can gather information on effort required during inhalation and voice quality while the tube is occluded. Patients may also be taught to occlude their trache tube with their ngers if their cognition is adequate. For longer-term use, the tube may be corked, capped or buttoned by placing the cork over the tracheal opening. A speaking valve is a one-way valve that is placed over the end of the trache tube in the same manner as a cork. It differs in that the patient can still take air directly into the tra che tube during inhalation. The valve then closes allowing air to be directed from the lungs up through the vocal folds so that speech can be made. Patients with thick viscous secretions or those that require frequent suctioning are not candidates for speaking valves. Patients who are unable to tolerate cuff de ation trials, or whose cuff cannot be fully de ated. Vocal fold paralysis, unstable medical or pulmonary status or cognitive affect would also be contraindications for use of the speaking valve. After a successful period of cuff de ation trials (24 to 48 hours), plus or minus occlusion trials, the team may decide to remove the trache tube (decannulation). Alternatives to decannulation include downsizing the trache tube over a period of days, or replacing the tube with a fenestrated tube. The rationale for these regimes is that the trache tube can ll somewhere between two-thirds and three-quarters of the tracheal space, leaving little space for the patient to ‘breathe around’ the tube when it is occluded. It also increases the likelihood of respiratory distress if the patient has an extremely narrow space to breathe through. There is also the risk of medical com plications or infections with increased frequency of tube changes. They found that using the 24–48 hours successful cuff de ation method was a reliable method for indicating when it was appropriate to decannulate the patient. In com parison with changing trache tubes and progressively downsizing or changing to a fenestrated tube, the patient was better off with the new ‘wait and see if they tolerate it’ method. Once the trache tube is removed, the wound is covered with a water-resistant dress ing. The patient will have to place his or her hand gently over the dressing and apply pressure to ensure that the air does not escape through the stoma site when coughing, talking and swallowing. These include: reduced laryngeal excur sion, ‘reduced pharyngeal sensation, reduced cough response, disuse atrophy of the laryngeal muscles, oesophageal compression by an in ated cuff, and loss of subglottic air pressure and glottic ow’ (Donzelli et al. The presence of an opening at the neck also affects the ‘valve’ system during swallowing such that there is ‘leakage’ of the system. The patient requiring ventila tion support loses the ability to use the natural swallow-respiratory cycle, with a pattern of respiration being forced upon them. Other less common complications include granuloma (an abrasion at the stoma site) and tracheoesophageal stula (where the tracheal and oesophageal walls become connected and communicate, advancing the risk for dangerous aspiration). Tracheoesophageal stulas can be caused by overin ating the trache tube so that there is pressure on the tracheal wall, which is immediately anterior to the oesophageal wall, or a nasogastric tube that is too large and causes rubbing of the same wall. There has been a change in the common indications for tracheostomy in the paediatric population. Introduction of endotracheal intubation in the 1970s and 1980s and the introduc tion of the haemophilus in uenzae type B vaccine has signi cantly reduced rates of acute epiglottitis and laryngotracheobronchitis, which had previously been man aged by tracheostomy tube (Had eld et al. The most common indications for paediatric tracheostomy now include prolonged ventilation due to neuromuscu lar or respiratory problems or subglottic stenosis. Other indicators for tracheostomy include: tracheal stenosis, respiratory papillomatosis, caustic alkali ingestion and craniofacial syndromes (Had eld et al. With advances in medical management of criti cally sick and premature infants, their survival rates have improved, which may explain the percentage of traches in young infants. The most frequent complication for paediatric tracheostomies is granulation formation around the stoma, with children under one year of age having a higher risk of complication (Midwinter et al. The most common complication of decannulation was per sistence of tracheocutaneous stula, the incidence of which was related to the age of the child (mean age 11. Tracheostomy tubes for the paediatric population are by necessity smaller in size and diameter to accommodate their smaller structures. The average paediatric tubes appear to commence at 3 mm, and can extend up to 7 mm depending on the brand purchased. Like the adult tubes, paediatric tubes can be cuffed or uncuffed, fenes trated or unfenestrated and come in a range of material types. One of the key differences between adult and paediatric tracheostomies and speaking valves is a method of explanation that is suitable to the child’s level of development. There is a range of commercial resources available to assist the clini cian in doing this. The clinician should also be aware that children may develop aversive behaviours towards speaking valves including coughing and breath holding. The behavioural element in children makes working with tracheostomy tubes in this population very challenging. Note that there is also a correlation between tracheostomy tubes and high risk of speech and language delay or de cit (Arvedson and Brodsky, 1992). More speci cally, slow development of sound acquisition, vowel production, the distinction between voiced and voiceless consonants, and excessive use of im mature phonological processes have been associated with children with a history of trachestomy prior to eight months of age (Kertoy et al. Clinical assessment of children with tracheostomy tubes should include a stand ard oromotor assessment, assessment of oral re exes, and clinical feeding evalua tion. Intervention typically covers oral stimulation or desensitization programmes (client speci c), taste programmes, oral trials and carer education sessions. Once this has been established to be adequate, the tracheostomy tube is reduced in size. Trache occlusion trials occur as per the adult regime, and a speak ing valve could be used if the patient is suitable. These sorts of drugs may impair the patient’s level of consciousness and thereby suppress the protective re exes necessary for swallow-respiratory co ordination (Palmer and Carden, 2003). Other drugs, such as the anticholinergics, have been linked with constipation, dry mouth, possible cognitive impairment and confusion, amongst other symptoms (Stanniland and Taylor, 2000). Neuroleptics are also known as antipsychotics and are often used in the treatment of psychosis and schizophrenia. Neuroleptic-induced Parkinsonism has been reported to occur in 12% to 45% of individuals, more commonly in the elderly (Sokoloff and Pavlakovic, 1997). It presents with the features of Parkinson’s dis ease, including the disorders of swallowing (described earlier). Again, once the medication is discontinued, the condition is eventually reversible. Antipsychotic medications can also result in an extrapyramidal presentation known as tardive dyskinesia. The oral, pharyngeal or oesophageal phases of swallowing may all be disrupted due to the dyskinetic movement and extrapyramidal symptoms. Factors that contribute to drug induced oesophageal disorders include fasting, recumbent position, reduced saliva production, not enough uid taken with the medication, duration of direct contact of the medication with the mucosa, pre-exisiting oesophageal disease, age and poly pharmacy (Jasperson, 2000). Older individuals are most at risk of drug-induced oesophagitis due to the fact that older people receive more medications (for multiple medical problems), they spend more time in a recumbent position, they produce less saliva, and may be prone to forgetting doctor’s instructions on correct ingestion of the tablet/capsule. Hyper or hypo oesopha geal sphincter disorders will also predispose the individual to oeosphageal injury. Note that in the case of pharyngeal motility disorders, it is equally possible for oral medications to collect in the valleculae or pyriform sinus post swallow, causing sim ilar local damage to the pharyngeal mucosa. Drugs that reduce lower oesophageal sphincter tone include: theophylline, calcium channel antagonists, benzodiazepines, nonsteroidal anti-in ammatory drugs (Kikawada et al.

Proposals for non-commercial reproductions and translations are welcomed and will be considered on a case by case basis. Functional imaging using nuclear medicine procedures has become an indispensable tool for the diagnosis, treatment planning and management of patients. This manual sets out the prerequisites for the establishment of a nuclear medicine service, including basic infrastructure, suitable premises, reliable supply of electricity, maintenance of a steady temperature, dust exclusion for gamma cameras and radiopharmacy dispensaries. It offers clear guidance on human resources and training needs for medical doctors, technologists, radiopharmaceutical scientists, physicists and specialist nurses in the practice of nuclear medicine. The manual describes the requirements for safe preparation and quality control of radiopharmaceuticals. In addition, it contains essential requirements for maintenance of facilities and instruments, for radiation hygiene and for optimization of nuclear medicine operational performance with the use of working clinical protocols. The result is a comprehensive guide at an international level that contains practical suggestions based on the experience of professionals around the globe. This publication will be of interest to nuclear medicine physicians, radiologists, medical educationalists, diagnostic centre managers, medical physicists, medical technologists, radiopharmacists, specialist nurses, clinical scientists and those engaged in quality assurance and control systems in public health in both developed and developing countries. Administration of radionuclides to women of child bearing age or pregnant patients. The present Nuclear Medicine Resources Manual offers guidance on human resources and training needs in the practice of nuclear medicine for medical doctors, physicists, technologists, technicians and nurses. Nuclear medicine physicians must be able to interpret the wishes of their clinical colleagues and demonstrate how clinical practice can be improved by the use of nuclear medicine techniques. It is, of course, imperative to achieve a certain standard of clinical practice before it can benefit from nuclear medicine. The introduction of complex nuclear medicine techniques for imaging or treating cancer with radiolabelled antibodies and peptides is only useful where there is an existing cancer service with qualified nuclear medicine staff at all levels. The present manual sets out the prerequisites for the establishment of a nuclear medicine service. Basic infrastructure should include suitable premises, a reliable supply of electricity, air-conditioning, temperature control and dust exclusion for gamma cameras and other equipment. Local government and customs officials must be familiar with the properties of radiopharmaceuticals and be prepared to expedite customs clearance procedures since radiopharma ceuticals decay if they are delayed in customs. The manual also contains details of the required instrumentation as well as instructions on maintenance and optimization of performance. There is also a section on practical clinical protocols and, unlike traditional textbooks where the emphasis is on outlining why protocols should be followed, this manual describes how they should be followed. It also stresses the importance of an accurate interpretation of results and describes pitfalls likely to be encountered. There are five parts in a nuclear medicine report: (1) the patient and demographic data; (2) the details of the test undertaken and the patient’s response; (3) A description of the findings; (4) A conclusion based on these findings; (5) the clinical data and request, and clinical advice as a result of the study. Nuclear medicine permits: (a) Investigations that establish a specific diagnosis, as in thyroid disease, pulmonary embolism or exercise induced stress fracture; (b) Investigations that aim to exclude a particular diagnosis, such as myocardial perfusion imaging (presence of significant ischaemic heart disease) or renography (presence of functionally significant renovascular disorder); (c) Follow-up investigations such as myocardial perfusion imaging after angioplasty or coronary bypass surgery, and the identification of tumour recurrence or metastasis using increasingly specific imaging agents. The range of applications and the clinical efficacy of internally targeted radionuclide therapy are growing. Conditions that are being successfully treated at present include neural crest, neuroendocrine tumours and non-Hodgkin’s lymphoma, as well as the effective palliation of the pain from bone metastases. Radiopharmaceuticals are the mainstay of nuclear medicine, permitting an increasingly specific yet sensitive demonstration of clinical pathophysiology. This manual describes the requirements for the safe handling, quality assurance and quality control of radiopharmaceuticals, as well as protocols for general radiation safety and radiation protection in nuclear medicine practices. It characterizes tissue, for example, as cancerous or not, but, at the same time, relies on quality assurance at all levels for hardware and software, as well as competence in technology, physics and medicine. The manual endeavours to demonstrate the universality of nuclear medicine, its uniformity and harmony. Other benefits of nuclear medicine include safety, non-invasiveness and cost effectiveness. In the future, there will be increased emphasis on distance learning and on ‘hub and spoke’ type systems, so that local data acquisition can be transferred to a centre for data analysis and for second, or specialist, reporting. As the pendulum of change swings towards free enterprise and market oriented economies, health care and medical services are also moving into the realm of business and industry. Efficient management is essential to the success of any undertaking, and nuclear medicine is no exception. It should be regarded as an enterprise that requires efficient organi zation and management if it is to adapt successfully to the pressure of change brought by the new market order. Human resources act as the hub that drives all the other resources in an enterprise, whether material or financial, and their strategic importance cannot be ignored. Human resources can be defined as the total knowledge, skills, creative abilities, talents and aptitudes of the workforce in a given organization, including the values and attitudes of the individuals making up the organization. No development is possible without proper planning, and human resource planning is a prerequisite to human resource development. Human resource planning in nuclear medicine must provide for the implementation of ongoing activities, meeting the demands of changing technologies and expansion programmes, replacing a workforce dwindling as a result of retirement or separation, and deploying staff to take care of any excess or shortage as the case may be. To summarize, the objective of human resource planning in nuclear medicine should be to optimize the human resource contribution to its growth and development, and to prepare nuclear medicine to meet the inevitable challenge of change. It is imperative to define the objectives of a nuclear medicine enterprise in order to forecast future needs. A comparison of current human resources with future needs will reveal deficiencies or gaps in the competence of the workforce and provide a framework for remedial action. Proper job analysis will lead to a clear division of responsibilities and avoid unnecessary duplication and overlap. These steps represent the groundwork for realistic and, above all, practical human resource planning. While doing all these, it is good to keep in mind that practicality should be given preference over perfection. In developing countries, the objectives of nuclear medicine can vary from country to country. They are borne out of the inherent strengths of nuclear medicine, namely its tracer principle and the capability to exploit newly emerging technologies to its advantage. The same goals can, however, also be defined from the more pragmatic point of view of medical imperatives. This is of particular relevance to developing countries, where there is a sense of urgency arising from the external challenges facing the practice of nuclear medicine today.

cheap cytoxan 50 mg with mastercard

Chapter 3 provides a detailed discussion about changes that occur to medications excessive sweating buy cytoxan 50 mg uids when barium is added to medications ok for dogs order cytoxan paypal them symptoms 8 months pregnant discount cytoxan 50mg otc. Ideally only suf cient barium should be added to symptoms 7 buy cytoxan us the uids to ensure that they are radiopaque. Barium has been used in the cooking of biscuits, bread and marshmallows so that taste is minimally affected and normal food texture is retained. It is not ideal to coat biscuits and bread in a barium liquid as it presents a mixed consistency (liquid and solid). Foods with mixed con sistency are often harder for dysphagic individuals to control, and may predispose them to further dif culties that may not be present if only a solid texture was used. Many uoroscopy suites keep barium pills; if not, it is possible to obtain empty capsules from pharmacy departments and place barium powder inside the capsules to observe how the individual manages in swallowing medications. Some elderly individuals have great dif culty swallowing tablets and this method may enable the clinician to observe their attempts and work on strategies to help make the process easier for them. Ideally the patient should test two to three swallows of each type of food or uid consistency of interest. A single swallow of a given consistency may not give a rep resentative view of how the individual copes with that consistency. There is a ten dency to provide small amounts of uids under the assumption that, if the uid is in fact aspirated, only a small amount will be aspirated. However, bearing in mind anatomy and physiology, we know that the average mouthful an individual will swal low is approximately 20 ml. Thus a dessert spoon or tablespoon amount would better assess this volume than a 1, 3 or 5ml bolus. Smaller bolus volumes may be useful for determining how the individual manages saliva swallows; however, these small amounts should not be used as indicators for how the individual would swallow at meal times. In the event that the individual has reduced sensory awareness, the small volume may serve only to slip under the ‘sensory radar’ and actually set the patient up to aspirate, the very thing we are trying to avoid. A more normal sized bolus may provide suf cient sensory cues to allow the oral and pharyngeal mechanisms to show a true indication of how they cope with a ‘normal bolus’. Note, that the 1 ml, 3 ml and 5 ml boluses are most likely to be suitable for paediatric clients given their smaller oral cavity for containment of the bolus. It is best to start the x-ray ‘on time’ when the patient is ready to commence swal lowing. It is not ideal to provide patients with a bolus and ask them to hold it in the oral cavity until told to swallow. This kind of scenario will predispose the patient with a poor ability to hold the bolus in the oral cavity to aspirate before the swallow. In addi tion, as noted in Chapter 4, there is a speci c sequence of events that is initiated when a bolus approaches and enters the oral cavity and this governs the inter-relationship between swallowing and respiration. By asking an individual to ‘hold the bolus till I tell you to swallow’, we upset this natural sequence of events, again potentially causing the already compromised individual to miss-time their swallow-respiratory coordination. The clinician may choose to include one such request for the patient to hold the bolus speci cally to determine the patient’s degree of volitional control, as this may be useful information when determining rehabilitation strategies. However, it is advisable to commence the study with the patient’s more usual pattern. It may be possible to inject small amounts of barium into the children’s mouth or buccal cavities if children are unwill ing or unable to take the barium for themselves. The clinician should be prepared to forgo the procedure rather than pursue a procedure where the child is clearly upset. In an agitated state the child is most unlikely to produce swallowing activities that are indicative of everyday feeding. It may be that the clinician must decide on the most important questions to be answered for this particular child at this particular time. When time is of the essence, the questions asked might include: • Is swallowing in uenced by the amount For safety reasons, individuals with a depressed level of consciousness should not attempt oral intake of any form. Similarly, a uctuating level of alertness would limit the generalizability of the results to the mealtime setting. The space between the x-ray tube and uoroscope is quite narrow – often only the width that is able to accommodate an airline wheelchair. Individuals with movement disorders, or those with dementia or cog nitive impairment, may be dif cult to assess and the ndings of the examination may be limited; hence these groups are only assessed where the need to determine swallowing safety is very great. It is in the best interest of patients to wait until their medical condition has stabilized before putting them through a radiological investigation, particularly if the medical condition is an in uencing factor in their dysphagia. Individuals who have already undergone a number of diagnostic or thera peutic radiological procedures may need to have good reason to undergo further radiation exposure. In Australia, the Australian Radiation Protection and Nuclear Safety Agency provides guidelines for dose limits per year for: • patients; • individuals involved in biomedical research; and • those who are occupationally exposed to radiation. Assessment of oesophageal dysphagia or dysfunction should be interpreted by the radiologist. Note, however, that a poorly functioning oesophagus can have an impact on swal lowing safety. For example, an individual with poor oesophageal function may have delayed oesophageal emptying into the stomach. Once the tube is full and with insuf cient emptying from below, physics deems the bolus will move back up, i. Note this is termed ‘oesophageal re ux’ and material can also be re uxed from the stomach back up into the oesophagus. So imagine now that the bolus has passed into the oesophagus, the oesophagus is too full to accommodate any further material and is not emptying at a suf cient rate to receive any further material. By this stage the swallow has been completed and the person has recommenced tidal breathing. This material that has pooled in the pyriform sinuses is now in a prime location to be inhaled into the larynx with each respiration, leading to aspiration after the swallow. The importance of this information is that the individual may present with an aspira tion pneumonia; however, it may well be from dysphagia of oesophageal origin that is impacting on the pharynx and larynx after the swallow. Re ux may be demonstrated most frequently when the patient is turned from the prone to the supine position (Jones, 2003a). An aspiration event affords the clinician an opportunity to determine why aspiration is occurring and propose an intervention. The intervention may be a modi cation in head or body positioning, the introduction of a swallowing manoeuvre or a change in the texture of the food or thickness of the uids offered (further details of these compensatory mechanisms are described in detail in Chapter 11). The clinician can review the physiology and determine the most appropriate compensatory technique (position, manoeuvre, change to diet texture or viscosity) and trial their hypothesis in the radiology suite to see if the modi cation does indeed prevent or minimize the aspiration. It is intended to diagnose and describe the anatomy and physiology of the oropharyngeal swallow. However, it is also intended to be used for therapeutic purposes to provide an account of whether compensatory strategies are, in fact, effective. The clinician needs to be able to make ‘online’ judgements during the procedure to determine which uid and food consistencies to test and which compensatory posi tions or manoeuvres to test (if any). In the initial phase of reviewing the tape it is useful to think of viewing the swallow as one might a car crash or a scene of devastation. In viewing a car crash, for example, the eye is drawn, darting, to various areas of the image – those with the most damage for instance. In the case of the swallow, the eye is often drawn directly to the larynx and the trachea – these being the most vulnerable areas. The worksheet concept would look to addressing questions such as: • What was the damage Critical areas to look at when reviewing a video uoroscopy are: • Ability to protect airway (penetration/aspiration) (hyolaryngeal region). This does not necessar ily mean that a linear, anterior-to-posterior, superior-to-inferior system should be used. It is suggested that in the initial phase of reviewing the tape, the clinician should follow the movement of the bolus. The bolus is processed in the oral cavity and the tongue deftly moves the bolus from the oral cavity into the pharynx. Hyolaryngeal excursion occurs, and also epiglottic de ection, with the bolus being progressed through the pharynx aided by the constrictors. This all happens in approximately 2 s in a normal swallow (detailed discussion in Chapter 1). Abnor mal events may include: • pooling of material in the oral cavity, pharynx proper, valleculae, pyriform sinuses or in structures such as a pharyngeal pouch; • aspiration and/or penetration; and • oesophageal transport abnormalities.

Coincidental with a change of workplace his pain was progressively getting worse (blue flag). The newjobwas associ atedwith working longer hoursand a b under hightimepressure(blue flag). Convinced that movement would harm him (yellow flag), he remained as inactive as possible while waiting for another consultation with his doctor. Resuming work was still not possible and by this time he had a compensation case pending at work and was required to obtain an independent medical evaluation (black flag). His family recommended quitting his job to avoid further damage to his back (yellow flag). He was immediately relieved but still sceptical as he could not completely understand what was causing his pain (yellow flag). He began a physical therapy regi men skeptically, but with increasing activity his motivation and compliance improved. Three weeks after the program start he was almost pain free but still unwilling to return to work because he felt discomfort in certain positions and when lifting heavy objects. He still believed that pain indicated damage and returning to work would injure his back (yellow flag). Evidence was provided by a psychologist to support the claim that “pain does not equal harm. This case introduction demonstrates the use of “flags” to identify obstacles to recovery. Non-specific Low Back Pain Chapter 21 587 Classification of Back Pain the term “low back pain” refers to more than 66 diagnoses [24]. The mechanical loading model includes that sustained end range spinal loading, lifting with flexion and rotation, exposure to vibration and specific sporting activities can have the potential for peripheral sensitization [55]. The signs and symptoms model is based on biomechanical and pathoanatomic signs in which the area and nature of pain, impairments in spinal movement and func tion, changes in segmental spinal mobility, as well as pain responses to mechani cal stress and movement play an important role [51, 56]. A standard ized physical examination is necessary to exclude possible specific conditions requiring further action. A history of trauma, systemic diseases, cancer, infec tion, or major neurological compromises may indicate serious spinal pathology. Such barriers to recovery should be assessed as soon as possible by the clinician and should be addressed with cognitive and behavioral interventions to avoid long term problems. Blue flags represent work-related predisposing factors for delayed recovery [50] Blue flags represent work such as fear of losing one’s job, monotony at work, lack of job satisfaction, and related predisposing factors poor relationships with peers and supervisors. Black flags relate to occupational and societal factors such as low income and Black flags are related to low social class [71]. These factors either lead to the onset of low back pain or occupational and societal promote disability once the acute episode has occurred (see Chapter 6). These guidelines were formulated by groups of interna tional experts considering the scientific evidence for physical and non-physical treatment of back pain. Today there are guidelines from many countries and their recommendations are quite consistent [45]. Since low back pain is self-limiting for the majority of medical intervention patients, minimal or no medical interventions are recommended for acute non is recommended specific low back pain [2, 84].

If necessary, over-the-counter medi cations should be used for pain relief [2, 84]. Medical Pain Management Over-the-counter medication should be used for pain relief whenever possible. If pain relief is insufficient, non-steroidal anti because of its low potential inflammatory drugs, such as acetylsalicylic acid, diclofenac or ibuprofen can be side effects prescribed. However, these medications can have serious side effects such as gas trointestinal and renal complications as well as a decreased platelet aggregation. The risk factors discussed above are asso ciated with delayed recovery and should be identified. Although there is sufficient evidence to recommend physical, therapeutic or recreational exercise, it remains unclear whether any specific type of exercise is more effective than any other [2, 77]. The type of exercise prescribed often depends on the training and preferences of the provider and may vary considerably. However, it is recommended that the exercises are progressive in intensity, duration and frequency [61]. Manual therapy includes other passive treatments such as massage and mobilization. They should only be used to con trol symptoms in conjunction with an exercise program, as an active approach provides the best outcome [14]. Spinal Manipulation Some studies have reported that a few treatments of spinal manipulation in the acute stage of injury can speed recovery [1, 78]. All “at risk” patients showing signs of “yellow flags” should be evaluated for psychological intervention. Cognitive techniques are introduced to reduce the negative cognitive techniques and response associated with pain [79]. These may include pain distraction tech coping strategies niques, reinterpreting symptoms, and the use of healing or calm imagery.

The coordination of care among providers is crucial to provide a consistent and clear message to the patient. Work Conditioning Programs the goal of work condition Work conditioning programs usually include exercise and fitness, and cognitive/ ing programs is to return behavioral and educational components [20]. Additionally, many of these programs simulate actual physical work tasks to prepare the patient to return to work after rehabilitation. Facet joints or epidural injections may be subjectively helpful but have not been proven to be effective. At 6 months after the onset of pain, conditioning programs the likelihood of a patient ever resuming normal activities is 40–55%, at 2 years, may prevent disability it is almost nil [82]. Work-conditioning programs may also help for the early chronic patient (<1 year) [20]. These types of programs should be considered if the patient has not previously tried aggressive physical therapy (see Table 1).
