Other etiologies for dysphagia include stroke, traumatic brain injury, head and neck tumors, ageing, generalized weakness, and other non-neurogenic causes. Dysphagia may have a major impact on the quality of life of patients and can lead to malnutrition, dehydration, or aspiration pneumonia (Park 2016). Dysphagia may occur at any phase of the swallowing process; in the oral phase when impaired lingual movements may lead abnormal bolus formation and manipulation; in the pharyngeal phase due weakening of the pharyngeal constrictors that are crucial for the transfer of the oral bolus from the mouth to the esophagus, decreased hyoid bone movement, and delayed laryngeal movements leading to pharyngeal residues and aspiration; or in the esophageal stage due to impaired upper esophageal sphincter movements. In addition, weakness of the respiratory and ventilatory muscles impairs the airway protection by reducing the expiratory pressure needed to produce effective cough.

Criteria | Codes | Revision History cerebellar and/or brainstem involvement and the weakness or paresis of the muscles important for the swallow function. The pathophysiology of oropharyngeal dysphasia in Parkinson’s disease is not clearly understood but is postulated to be due to dysfunction of the brain stem, degeneration of the substania nigra, as well as disturbance of nondopaminergic neural networks (Van hooren 2014, Park 2016, Byeon 2016, Plowman 2016, Silverman 2017). The remedial approach with the goal of improving swallowing function through different exercises; and 2. The compensatory approaches however, have a temporary effect and cannot induce recovery of the damaged swallow network. Investigators have thus focused on the remedial approaches that aim at restoration of function. Different new therapeutic modalities for managing swallowing in neurologic disorders have been developed and introduced to practice in the recent years, such as neuromuscular electrical stimulation, deep brain stimulation, respiratory muscle training, and others (Byeon 2016, Park 2016). It is an exercise program that focuses on increasing the force‐generating capacity of the expiratory muscles during breathing with the aim of improving the maximum expiratory pressure, voluntary coughing effectiveness, as well as improving displacement of the hyoid during swallowing. Researchers explained that during the swallowing process suprahyoid muscle contraction in the pharynx pulls the hyoid bone in the anterior superior direction, and that sufficient movement of the hyoid bone in this direction is associated with airway protection and safe swallowing such as opening of the upper esophageal sphincter during swallowing. Neurogenic disorders may result in weakness of the suprahyoid muscles (anterior belly of the digastric, mylohyoid, and geniohyoid muscles) that are important for coughing and breathing out forcefully and swallowing. Weakness of these muscles leads to insufficient movement of the hyoid bone and in turn reduces the cough capacity and airway clearance. It was initially investigated in the early 2000s by a team of researchers in Florida as a swallowing rehabilitation intervention in patients with Parkinson’s disease (Pitts 2012, Laciuga 2014, Eom 2017, Moon 2017, Park 2016, Pearson 2017, Silverman 2017). Expiratory muscle training is performed by hand-held resistive or pressure threshold devices. The resistance based devices rely on adjusting the diameter of the airflow vent holes in the device. Reducing the dimeter of the vent holes imposes resistance requiring increases respiratory muscle force. These devices have no threshold for the user to overcome and can be ineffective for strength training if used with inadequate airflow. Pressure threshold devices on the other hand, rely on the pressure exerted during expiration. The device has a pressure threshold relief valve that opens only when a sufficient expiratory pressure is generated by the user during a forceful expiration into the device. Once the targeted pressure is produced, the valve opens, and air begins to flow through the device. The latter allows adjusting the pressure amount in a range between 0 and 150 cm H2O. During training the pressure threshold device is adjusted incrementally to progressively increase the resistance (progressive overload). The expiratory force must be sufficient to open the spring-loaded valve and allow the air flow. If the expiratory force is inadequate, the valve will not open and no air will flow through the device. When training ceases or the body undergoes a long period of detraining (inactivity) following a period of physical training, it loses some or all the positive gains achieved during training. This suggests that training should take place continually to maintain the benefits of an exercise program, particularly in individuals with neurodegenerative disease emst150. Back to Top Date Sent: 3/24/2020 397 these criteria do not imply or guarantee approval. The trials were too small with attrition bias and examined the effect of the therapy only for the duration of expiratory training (4-5 weeks), which does not allow examining the durability of effect after discontinuation of the therapy. In addition, the published trials generally included patients in the early stages of the disease/disorder or those with mild to moderate dysphagia and may not be generalized to more severe or advanced cases who may not benefit from or tolerate the treatment. Both the active and sham therapy groups showed some improvement in the swallow quality of life. In addition, the authors compared pre-post outcomes within each group and not between groups. The authors reported that the detraining effects on swallow safety was less clear and concluded that the results of this study indicate that there is a need for the development of maintenance programs to sustain function following intensive periods of training. The postural techniques included chin tucking, head rotation, head tilting, bending head back and lying down straight for 30 minutes per session. The trials were conducted by the same team of principal investigators in university hospitals in Korea, which makes it difficult to rule out a potential overlap between the participants. All three trials had similar protocol, intervention, outcome © 2018 Kaiser Foundation Health plan of Washington. Back to Top Date Sent: 3/24/2020 398 these criteria do not imply or guarantee approval. To avoid introducing bias by duplication the results for the overlapping participants, the largest and most recent trial (Eom et al, 2017) was selected for critical appraisal. The two groups underwent training for 4 weeks (5 sets of 5 breaths 5 days a week for 4 weeks). The improvements observed were significantly better in the active treatment group. However, it was a very small trial, conducted among patients with subacute stroke and the improvement, as observed in the placebo group, may be due to the natural neurological recovery of the condition and not due to the intervention. In addition, the study period was only four months and insufficient to determine the long-term durability of the observed effects. All participants were instructed to complete 5 sets of five repetitions (total of 25 times in approximately 20 minutes /day) 5 days a week for 5 weeks. There was no significant difference between the 2 groups in the total swallow score. In addition, the study period was only five weeks, does not allow examining the long-term durability of observed benefit, and the authors had financial ties with the industry.

The efficiency of evacuation is determined by the availability and coordination of transport gastritis raw food diet buy on line pyridium, either by air (fixed wing with 161 war surgery airports or helicopters and helipads) gastritis diet and recipes purchase 200mg pyridium visa, or by land (proper roads symptoms of upper gastritis buy cheap pyridium line, necessary vehicles gastritis diet purchase pyridium from india, etc gastritis diet quick discount pyridium 200mg on-line. Scoop-and-run implies basic life-saving frst-aid measures, then taking the patient immediately to a surgical hospital. This is appropriate if the distances are short, reliable transport is available, and the nearby hospital is adequately supplied and stafed. Keeping patients on the spot until patient stabilization prior to evacuation – stay and treat – is correct if distances are great, infrastructure and transport are less than adequate, and proper surgical facilities are more difcult to access. In a military context, the factors of ongoing combat and enemy activity must be added to those present during peacetime. Here, scoop-and-run implies air superiority if helicopters are used, safe and controlled roads for transport over land, and, in both situations, surgical facilities at a reasonable distance. These conditions are fulflled for only a few armies in the world, and even then only under certain tactical situations. More common is the establishment of a collection point or clearing station: that is to say “stay-and-treat”. The performance of more advanced techniques in the feld has been discussed in Chapter 6. Blunt trauma above the level of the clavicles or causing unconsciousness requires immediate observation and immobilization of the cervical spine, while still giving priority to the airway. A penetrating wound to the brain causing unconsciousness requires no special care of the cervical spine. In the case of a penetrating missile wound to the neck hitting the cervical vertebrae, any damage to the spinal cord has already been done. Unstable cervical spine injury from a projectile results in permanent cord injury. The frst aider should be careful while handling the casualty, but cannot prevent damage that is already irreversible. A combination of blunt and penetrating neck injuries should be managed in the same way as blunt ones. A bullet wound to the mandible – with bone fragments, haematoma, drooling saliva, and damaged soft tissue of the foor of the mouth – does not. There is no use in placing a protective cervical collar on this patient and, if the frst aider attempts to place the casualty in a reclining position, the wounded person will resist. Loss of consciousness due to a bullet wound to the head, however, does not require any specifc precautions regarding the cervical spine. In statistical terms, severe peripheral haemorrhage is the main lethal yet salvageable injury in a context of armed confict (see Chapter 5). Various studies show that far more soldiers die from catastrophic peripheral haemorrhage than from airway obstruction or respiratory inadequacy. Thus, the “C” which stands for Catastrophic bleeding, may be put frst, simply because it is more common. It is difcult to apply correctly and to maintain and supervise, and open to many complications if widely used when not necessary. Furthermore, the prolonged application of an improvised tourniquet is usually not efective and causes tissue damage by itself (Figures 7. There is little or no use for a tourniquet in civilian practice for the war-wounded. It may be applied as a last resort, when all else has failed, to temporarily control bleeding while packing the wound and applying a compressive bandage. Here a tourniquet was applied for more than six hours, resulting in a very high above the knee amputation. By far the most common and most efective technique for a frst aider to control peripheral haemorrhage is direct pressure over the wound completed by a compressive bandage; or, if insufcient, pressure over the proximal artery in the axilla or groin, tamponade of the wound with dressings, and then a compressive bandage. The military might continue to use a tourniquet under certain tactical circumstances: to free the hands of the single medic when dealing with mass casualties; while performing frst aid under direct fre, and especially at night. Some armies equip their soldiers with a pre-manufactured self-applicable tourniquet applied with one hand to allow a wounded soldier to continue participating in combat. The use of a tourniquet for crush injuries (people trapped under the rubble of a collapsed building whether due to an earthquake or bombardment) is justifable, and due precautions should be taken to ensure rehydration/resuscitation and thereby avoid the complications of the otherwise inevitable myoglobinaemia. New locally-active haemostatic powders and sponges to promote clotting in traumatic wounds are being tested by some armies; however direct pressure must still be applied. Cost and availability will be factors to be taken into consideration for their use worldwide. Peripheral haemorrhage can be controlled by external pressure and a compressive bandage. The administration of intravenous fuids requires a certain degree of medical knowledge and specifc equipment that are beyond the normal scope and competencies of a frst aider. Maintaining adequate tissue perfusion and oxygenation is balanced of against the dilution of clotting factors and the dislodging of existing clots when the blood pressure goes up (“popping the clot”). The currently recommended “hypotensive resuscitation” involves giving fuids to a just palpable radial pulse – equivalent to a systolic blood pressure of 90 mm Hg – and no more (see Chapter 8). A great deal of this controversy concerns efcient civilian trauma systems where evacuation times are short, less than 2 hours. It is probable that only the war-wounded showing obvious clinical signs of shock require pre-hospital i. In addition, in many contemporary conficts transfer to a hospital takes much longer – days or even weeks – where “popping the clot” is not really relevant. Rehydration – as part of resuscitation – may be a more appropriate term under these circumstances. If the wounded patient is conscious and not sufering from head trauma, the frst aider can rehydrate with oral fuids. Oral rehydration can probably be given with no detriment to the patient even in cases of abdominal trauma, and especially for severe burns. Oxygen cylinders are the equivalent of a bomb if hit by a bullet or piece of shrapnel. In addition to the danger they represent, the cylinders are heavy and must be replaced, lasting only a short time at high fows. Furthermore, their replenishment is complex and requires special factory capacity. Oxygen cylinders must be ruled out in the event of any deployment to a dangerous area. Depending on security conditions, the collection point or intermediate station may have oxygen available. An oxygen concentrator (requiring an electrical supply) is preferable to compressed cylinders. It easily translates into the Glasgow system when the patient arrives at the hospital and gives the surgeon a good appreciation of the evolution of the patient’s condition. Alert the casualty is awake, lucid, speaks normally and is responsive to the environment. Voice responsive the casualty is able to respond in a meaningful way when spoken to. Pain responsive the casualty does not respond to questions but moves or cries out in response to a painful stimulus (pinching the neck muscles, earlobe or nipple; rubbing the supra orbital margin, or the angle of the mandible). Other conditions may infuence the level of consciousness: hypoxia, shock, medication, and narcotics and alcohol (the latter all too often consumed to excess during times of armed confict). In the feld, securing the airway is the frst step to take when facing a casualty whose consciousness is compromised. Palpation of every vertebra – like “fngers playing on piano keys” – aims to identify any induration 7 or deformity. If there is any danger to the spinal cord, then the four-person log-roll technique should be used to move the patient onto a stretcher. The cervical spine can be immobilized initially by manually controlling the head before a neck collar/ Minerva splint is placed. Immobilization of the cervical spine must not increase the risk of airway obstruction, however. The importance of the mechanism of injury, blunt or penetrating, has already been mentioned. In all cases of suspected injury to the vertebral column, proper handling of the patient and immobilization techniques are of the utmost importance; the injury may already be there, but the frst aider should act in such a way that he does not worsen the condition. In situations of armed confict, Diferent means of patient evacuation: modern the danger of the ambulance ride is complicated by the risks of ongoing combat. All these parameters, aggravation of the patient’s condition, use of resources and security, must be weighed against the likely benefts of moving the wounded. In an urban environment, it is normal for a frst aider to bypass the neighbourhood clinic if the injury is serious, and to evacuate to a clinic for a minor wound in order not to overburden the hospitals. Unfortunately, city-dwellers often spontaneously rush patients to hospital no matter how slight the injury. Evacuation and transport may be difcult and dangerous during urban fghting even if distances are very short and transfer may be delayed while waiting for a calm period or ceasefre. There is also the confusion that reigns during street fghting and the highly-charged emotional atmosphere to contend with. Lack of discipline to perform good pre hospital triage – and the “pressure” of bystanders – can result in chaos in the receiving hospital. The second wave of ambulances carries people who are shouting, hysterical, and frightened: the lucid and superfcially injured. The third wave evacuates the seriously wounded who truly require emergency treatment; these patients lie still – they are usually haemorrhaging – without shouting to bring attention to themselves. In remote rural areas, if transportation takes many hours or even days, it is logical to project forward competencies by training local providers in more advanced skills. The principles of triage apply to the choice of which patients to evacuate frst (see Chapter 9). Note that there is an important diference in the priority to treat and the priority to evacuate, especially if evacuation is prolonged. The recognition of injuries that are not survivable helps to spare the victim and would-be rescuers the agony and frustration of unsuccessful eforts to reach a higher level of care, and to provide better care for those who can survive. Delay in evacuation will contribute to an increase in pre-hospital mortality; the more severely injured sufer “nature’s triage”. As was seen in Chapter 5, longer and more difcult evacuation sorts out central injuries, with a consequent decline in hospital mortality: only those patients with a good chance of survival reach the hospital. The logic is the same; the diagnostic and treatment means available are simply more advanced. The patient’s condition may have changed during transport; important wounds may have been missed because of the confusion in the feld; frst-aid competence may have been limited or entirely absent. Eforts should again frst concentrate on lifesaving treatment for asphyxia and shock, the most common remediable causes of death. The “golden hour” begins at the site of trauma, not on arrival at the emergency room. Please note: In certain countries a very defnite separation must be made for emergency examination and treatment of male and female patients.

Finally gastritis diet book discount pyridium american express, the conclusion underscores the need to gastritis in children cheap pyridium 200mg online continue enhancing the exchange of emerging technologies between space programs and commercial industries gastritis ranitidine discount pyridium on line. Principles for Designing Analytical Equipment for Use in Space: an Overview Equipment designed for use aboard spacecraft must meet strict requirements in terms of size gastritis upper left abdominal pain order 200 mg pyridium otc, weight gastritis symptoms in pregnancy cheap pyridium uk, volume, power, ease of use, and reliability in addition to being able to function without the influence of gravity (Fig. Although few devices meant for operation on Earth were designed to operate independently of gravity, the other constraints on spacecraft hardware, especially portability, ease of operation, and ease of interpreting results, have led to the development of equipment that expands some capability in Earth settings as well as in space. Moreover, automation, the goal of which for space activities is to minimize the need for intervention by busy crews, also can reduce the need for labor-intensive, time-consuming procedures on Earth, and can extend clinical capability far beyond traditional service points such as hospitals or laboratories. Many research tools for space flight applications began as off-the-shelf equipment that was modified to reduce the size of the component systems. A prototype clinical chemistry analyzer, for example, evolved from a large stand alone device to a small bench-top unit, and from there to a device the size of a toaster. Another example is a tiny ear oximeter-transducer, developed at Ames Research Center, to measure blood oxygen saturation, blood pressure, 1 pulse rate, and pulse pressure during space flight. Other aspects of the spacecraft environment aside from size can drive the development of entirely new analytical techniques. For example, when the need for measuring blood electrolytes during space flight first became apparent in the early 1970s, the analytical methods of that time required the use of flammable gases. Since flammable materials are prohibited aboard spacecraft, another approach was required, and new analytical instruments were developed that used ion-specific electrodes to measure individual electrolytes. The first commercial clinical laboratory instruments capable of measuring more than one electrolyte—in this case sodium and potassium—were a direct result of this work. The evolution of portable clinical blood analyzers has continued well into the 1990s; one current device being assessed for routine use in the U. Another application conceived to meet spacecraft safety requirements that has proven useful on Earth is a water 4,5 treatment device that quickly and easily disinfects drinking water. Patent 5176836) is a self-replenishing resin bed that imparts biocidal amounts of iodine to recycled drinking water. This water-treatment device is especially useful for treating water supplies that may have been contaminated through floods or other natural disasters. A final example, an automated microbial analysis system, represents a particularly elegant combination of miniaturization, speed, automation, and ease of use. Traditional methods of screening biological samples for potential pathogens can take up to 4 days. Speeding up this process can reduce hospital stays by allowing infectious agents to be identified more quickly, as well as reducing the indiscriminant use of antibiotics to treat unidentified 6,7 infections. Inventors of another system devised for use in space have miniaturized and automated the process by which microbial pathogens are identified and their susceptibility to antibiotics tested. Tiny samples of body fluids are injected onto disposable credit-card sized microplates. Each plate contains 16–30 wells that hold chemical substrates for microbial growth or inhibition, which are chosen so that a positive reaction generates a change in color or turbidity in the well. The treated cards are placed in trays, which in turn are placed in a reader/incubator module. The system scans each well for chemical reactions every 60 minutes, and compares the reactions taking place with those in a computerized database of identified microorganisms. Once an organism is identified, the sample is tested in the same way for susceptibility to several antibiotics. The entire process takes between 4 and 13 hours, compared with two to four days for traditional culture preparations. This system allows Earth-based microbiology laboratories to provide guidelines for antimicrobial treatment within one day of specimen collection. Other advantages include the minimization of human error, reductions in technician time, and increases in laboratory output. This system also has broad applicability beyond medicine, such as in food processing; identification of biological indicators or contaminants in sterilization processes; and in-plant environmental testing. Imaging And Image-Processing Technologies Advances in electronics, computers, and miniaturization technologies developed in the course of space exploration have proven particularly valuable for imaging applications. The potential scope of these applications is enormous; the nondestructive testing and visualization allowed by X-ray imaging, for example, can be used for everything from production and quality-control testing to ensuring security at buildings or airports. The FluoroScan also allows images to be created in real time, so that visible structures can be monitored 8,9 continuously. The development and use of sophisticated imaging techniques and systems has revolutionized the field of microscopy, and in combination with advances in computer technology continue to produce many new applications every year. Among the most exciting applications of imaging technology in medicine are its uses in microscopic diagnosis, surgery, and other forms of treatment. Next are described two additional imaging applications, designed to aid people with visual impairments. The final component of this section on uses of imaging and image-processing technologies focuses on the use of global geographic images to track patterns of disease transmission around the world. In these techniques, patients are given short-lived radionuclides that emit photons when they react with active tissues; computers are used to trace the path of these particles and to produce composite images of metabolic and physiological functions in those tissues. This “virtual workbench” system allows images of the cranial exterior and interior to be manipulated freely. The system can be used for “phantom surgery,” which allows physicians to plan—and safely practice—various surgical approaches. It also allows patients to see the potential results from complex craniofacial surgery before that surgery is begun. This type of imaging depends on the reaction of hydrogen atoms in tissue to harmless radiofrequency pulses, and can generate extremely detailed images of the human body. Another more specialized use of image-processing technology forms the basis of percutaneous transluminal or “balloon” angioplasty. In this type of surgery, cardiologists use a digital cardiac imaging system, originally developed for Earth-resources survey satellites, to manipulate images to guide their progress during angioplasty and 13 to compare vessel patency before and after the procedure. Those patients who cannot withstand the balloon angioplasty procedure may benefit from another type of microsurgery that also represents a spin-off from space technology. In this type of microsurgery (“excimer laser angioplasty”), a tiny fiber-optic probe that contains a laser beam, light source, and camera lens is threaded through a stenosed (constricted) artery. Areas of atherosclerotic plaque formation are visualized and then excised or reduced with short bursts of ultraviolet light, which generates considerably less heat than conventional thermal lasers. Precise control of the laser pulse is made possible by a system of magnetic switches originally developed at the Jet 14,15 Propulsion Laboratory to measure gases in Earth’s atmosphere. Mammography Astronomy and breast-cancer detection share several common imaging requirements. Both require high resolution, 16 so that minute details can be visualized, and both must be operable over large ranges of illumination. Digital mammography has several advantages over film-based X-ray imaging systems for detecting breast cancer early and reliably. Difficulties in expanding the image format from the previous limits of about 3 cm by 3 cm to a more practical 18 cm by 24 cm led the U. This system represents substantial improvements in accuracy over excisional or core-needle biopsy techniques, and eliminates the need for 24 general anesthesia during the biopsy procedure. In addition to being less traumatic for the patient, this form of biopsy is much less expensive than traditional surgical biopsy techniques. Other aspects of the technology developed for the Hubble Telescope also are being used to expand the image format to a size useful for imaging the entire breast. Diagnoses then could be made more easily by comparing a baseline image taken of a healthy breast with images of the same breast collected over the course of subsequent examinations. In this technique, the array is moved across a target area, multiple 25 images are collected, and the final image is reconstructed with computer software. The “Brigit” device, being developed by investigators at the Lawrence Livermore National Laboratory, Fischer Imaging Corporation, and the University of Toronto, includes an X-ray source that can be tuned to various wavelengths, which in combination with its unique detector design is expected to produce superior image quality with 19 significantly less radiation exposure than conventional mammography units. Other aspects of digital mammography that have been targeted for development involves developing and validating 18 new algorithms, neural networks, and other forms of machine intelligence for computer-aided diagnosis. In one such project, members of the Space Telescope Science Institute are adapting image-processing algorithms used for various experiments with the Hubble Telescope for detecting clusters of microcalcifications within the breast, an early indication of possible malignancy. Another project underway at Bilkent University in Turkey is focusing on automating the detection and enhancement 28–30 of microcalcifications from digital mammogram images. Information about the size and location of these crystalline agglomerates can be presented on a three-axis grid, or in color images dubbed “cataractograms. The probe device was demonstrated in the October 1996 meeting of the American Academy of Ophthalmology as one of 15 technologies judged likely to affect the practice of ophthalmic care in the next century. Preliminary tests of the probe in anticipation of clinical trials are underway at the U. The inventors of this device hope to be able to expand its capabilities to 4 V 4 Ch 14 Terrestrial Benefits Nicogossian et al. The unit can zoom from two inches to infinity, can provide up to nine times magnification at distance and up to 25 times at near, and is completely portable. The cameras feed video images to a computer, which corrects for the individual’s particular vision problem, and forwards the images to the video display in the goggles. The underlying optical scanning technology was used by Ames Research Center and the Stanford Research Institute for the “Viking” series of Martian-surface explorers. The user passes a small camera over a printed page with his or her left hand; a control unit processes the image and translates it into a vibrating tactile image of the words the camera is viewing, and the user touches the vibrotactile pin array to “read” the words (Fig. This system can be used with nearly any alphabet or language, and is in use in more than 70 countries. The new device uses the same basic technique of converting printed information into a tactile image, but connects directly to a desktop computer and allows the user to read graphic images as well as text. The new device also is completely portable, and can be run on battery power for up to 8 hours. Further improvements to this and 35–37 related devices are expected to include haptic representations in addition to tactile images. Using Remote Sensing and Computer-Based Geographic Information Systems to Track Vector-Borne Infectious Diseases the international medical community has become concerned over the recent global emergence and reemergence of 38 infectious disease (Fig. Techniques developed in space for observing geographical and environmental factors on Earth (Fig. Key environmental elements such as elevation, temperature, rainfall, and humidity influence the presence, development, 39 activity, and longevity of pathogens, vectors, zoonotic reservoirs of infection, and their interactions with humans. The type and distribution of vegetation also are influenced by these variables, and can be expressed as landscape 40 elements that can be sensed remotely and their interrelationships modeled spatially. Landscape pattern analysis, combined with statistical analysis, allows us to define landscape predictors of disease risk that can be applied in larger regions where field data are unavailable. The first phase of this effort involved developing landscape models to follow the dynamics of the Anopheles albimanus Wiedemann mosquito, an important vector for malaria, in California rice fields. Results from this effort verified that high-anopheline-producing fields could be identified with more than 90 percent accuracy 54 two months before peak anopheline production. Next, this landscape model was extended to Chiapas, Mexico, along the Pacific coastal plain, with the goal of modeling malaria vector/human contact risk within villages in this region. The proportions of transitional swamp and floodable pasture in these areas were found to be the best predictor of mosquito abundance within a village. These factors, in combination with demographic data, will provide specific predictors of which locations are at high risk for human malaria.

Gunshot wounds carry a heavier burden than injuries due to gastritis diet cheap pyridium uk fragments; but burns and anti-personnel landmine injuries represent the heaviest hospital workload and morbidity gastritis quimica purchase pyridium 200 mg with visa. The Red Cross Wound Score allows a good appreciation of the severity of war wounds gastritis what to eat discount pyridium, and the surgical workload that they represent. Age and sex, the cause and anatomic site of injury, and the time lapsed between injury and admission are recorded for each patient. Projectile injuries are scored according to the Red Cross Wound Classifcation System described in Chapter 4. The emphasis is on surgical workload as described by severity of injuries, number of operations per patient, number of blood transfusions required, and length of hospitalization. As at 31 December 2007, the database contained the records of 32,285 war-wounded patients.

Notable exceptions were the frst-aid posts set up near the Afghan border with Pakistan and close to Kabul. B setting up a surgical database for the war-wounded the following categories can be recorded in an electronic database (Approach) or listed in the columns of a simple spreadsheet. The number 1 wound should correspond to the number 1 anatomic region; wound 2 for number 2 anatomic region. Modern armed confict embraces classical war between conventional armies, urban combat between militias, and isolated and sporadic but ferce guerrilla attacks in remote rural areas. It may involve mass confict or chronic irregular, low-intensity combat, or individual terrorist attacks. Field situations vary considerably, but basic medical problems for the wounded are universal. A system must be developed and adapted to deliver the best possible care in a timely manner, under all circumstances. Landmines and unexploded cluster munitions continue to cause victims after the confict has ended. The system of evacuation and treatment of the sick and wounded – the chain of casualty care – like any chain, is as strong as its weakest link. The setting up of such a system requires planning ahead of time: an assessment of the tactical circumstances must be made; an analysis of the physical limitations and human resources carried out; and the resulting plan implemented. Wounded patients are transferred along a chain of medical care, beginning with simple “life and limb-saving” procedures and continuing to ever-greater levels 6 of sophistication. The principle of echelons of care in a military system has been described in Chapter 1. In civilian practice patients also tend to follow a chain of evacuation and treatment although, in many countries, this is not very efcient. The wounded and sick have the right to be cared for and to have access to appropriate medical care. The red cross, red crescent and red crystal emblems symbolize the legal protection aforded the casualty and the medical personnel, who have the right and the obligation to care for the wounded and sick. The protective quality of these emblems is a function of the training and degree of discipline of the combatant forces, and their adherence to internationally accepted norms of behaviour on the battlefeld: the Geneva Conventions and their Additional Protocols. This protection begins with the frst aider in the feld and continues through all the levels of treatment. Special measures must be taken to prevent further injury to any casualties and to protect them from the elements (see Chapter 7). Specialized centre: defnitive surgical treatment including reconstructive procedures; physiotherapy and rehabilitation, both physical and psychological. Treatment on the spot may be self or “buddy”-treatment, or practised by a military medic or frst aider. First aid starts at the point of wounding, but can be given anywhere and everywhere along the evacuation line to the place of defnitive treatment. The closer to the battlefeld, the more prominent will be the role of military medical services. In purely civilian rural settings, village health workers, nurses or medical assistants are often the only health professionals available. Collecting the wounded at one specifc location allows for the proper organization of feld triage and their efcient evacuation. Besides basic frst aid and trauma life support, resuscitative measures may be begun here. A health centre or rural hospital might represent the intermediate stage, where more sophisticated resuscitation and emergency surgery are available. Efcient evacuation of the wounded to defcient surgical facilities is not an efective chain of casualty care. Levels of hospital competency difer from country to country and between geographic regions. These hospitals are usually stafed by general practitioners or medical assistants with some surgical training and equipped with a minimum of proper surgical facilities. The military equivalent is usually a forward feld hospital specializing in damage control and resuscitative surgery. There are factors external to the hospital, involving an analysis of the national and provincial health systems, and internal factors: hospital infrastructure, administration and functional organization, departments, available resources, medical personnel (number and expertise), non-medical support services, fnances (see Annex 6. Assessment results of a typical hospital in a low-income country disorganized by war. The pie-charts above show the various factors that afect the functioning of a hospital dealing with the added burden of war-wounded patients compounded by the constraints of a weakened health system, and help identify dysfunctional areas. An additional factor is the emotionally stressful presence of casualties who are related to, or friends of, the medical staf. Transport of some sort provides the connection between the diferent echelons of the chain of casualty care. It uses up additional resources and involves security risks (“mortality of the ambulance ride”), and perhaps even exposure to military activity. These extra costs must be weighed up against the likely benefts of moving the wounded. In many contexts, the availability of transport for the sick and wounded is almost a “luxury”. Moving wounded people is difcult, always takes longer than expected, adds to the trauma, and is often dangerous. Circulation of information between the diferent levels is assured by some means of Figure 6. Mobile telephone systems have a tendency to stop functioning – carriage ambulance. The efciency of the command and communication systems depends on strict observance of established procedures. The availability of advanced procedures closer to the battlefeld has many advantages. It allows quicker access to “life and limb-saving” emergency measures, thus decreasing both mortality and morbidity. The projection of resources applies particularly to treatment at the intermediate stage, but can be applied to any echelon in the chain. Forward projection of resources allows quicker access to life and limb-saving measures. When a front-line hospital is coming under bombardment, putting both patients and 6 personnel at risk, there is little point in attempting more than frst aid if evacuation to another facility is possible. Only a minimum of equipment is necessary for well-trained medics to perform endotracheal intubation or place a chest tube, and then quickly evacuate the patient. A secure building with adequate resources may be used as an intermediate stage where a forward surgical team may perform damage control and resuscitative surgical procedures. All of these possibilities will depend on meeting the criteria defned above; but especially on security and human expertise. Infrastructure, equipment and supplies must all meet minimum requirements, and be appropriate to the task under the prevailing conditions. The most important factors determining the forward projection of medical care for the war-wounded are security and human expertise. The appropriate choice of procedures to undertake for the injured outside a formal hospital setting will depend on the factors mentioned above, and will vary from country to country, and even from region to region within the same country. The organization of any chain of casualty care for the war-wounded – military or civilian – should rely on a large dose of common sense to determine what is practical and what can realistically be accomplished to assure the best results for the greatest number, while at the same time guaranteeing the safety of the injured and the health workers. What exactly can be done for the injured outside a formal hospital setting will depend on the particular circumstances and means available. There is no dogma to be followed blindly; situations are diferent and improvisation and adaptation the key to success.

In some armies or countries, the organization may be so efcient that a wounded soldier may expect to receive treatment virtually as sophisticated as the care available to him in peacetime. In developing countries, however, the healthcare system might already be weak before the confict and may almost cease to function because of it. Water and electricity supplies can be unreliable, trained staf often fee the area, drugs and disposable equipment cannot be replaced, budgets and salaries are not paid, and buildings are destroyed. This mobile team “goes to the wounded” rather than having the wounded come to a hospital; the chain of casualty care is turned upside-down. This 2 In armed conficts, under international humanitarian law, civilians are permitted to collect and care for the wounded and sick of whatever nationality, and shall not be penalized for doing so. For the military, there is a balance between the needs of the wounded soldier and the necessities of combat. Some armed forces may teach the use of the self-applied tourniquet, which purportedly allows a wounded soldier to continue shooting. Part of emergency preparedness is the capacity to respond to a situation of armed confict or internal troubles, as well as natural disasters. Ministries of public health and National Red Cross/Red Crescent Societies usually also have a disaster plan, which should be integrated into the national emergency preparedness programme. Those who have to face the challenges of armed confict should understand how to proceed in setting up a chain of casualty care. The best possible outcome for wounded people can only be achieved with proper planning and training.

Colquitt and colleagues’ 2014 systematic review and meta-analysis on surgery for morbid obesity was the last published update of previous Cochrane reviews and updates on that topic conducted by the same group of authors over the last decade. The meta-analysis included 15 trials (N=1,180 participants) that compared different bariatric surgery procedures used for weight loss (seven additional trials compared surgery to non-surgical weight loss therapies). The meta-analysis had valid methodology and analysis, but the majority of the studies included had uncertain or high risk of bias. The studies had relatively short-term follow-up durations, which was insuffient to study the long-term effects of the surgical procedures. The meta-analysis combined the results of a small number of randomized and non-randomized studies with small sample sizes and short-term follow-up durations. The study was large and included a diverse group of patients but was retrospective and not randomized. Data were obtained from records which did not included all required information, and the subsequent interventions and hospitalizations may have been due to causes unrelated to the bariatric procedures.

The authors could not perform a meta-analysis due to the heterogeneity of the studies but performed some cumulative analyses when suitable. Buchwald and colleagues (2009) performed a systematic review and meta-analysis of 621 experimental and observational studies (N=136,134 participants) on bariatric surgery that were published in English between 1990 2006, and that reported on the resolution of type 2 diabetes. Nineteen studies with 43 treatment arms and 11,175 patients reported on both weight loss and diabetes resolution separately for diabetic patients (N=4,070). Weight loss and diabetes resolution were greatest for patients undergoing biliopancreatic diversion/duodenal switch, followed by gastric bypass, and least for banding procedures. Insulin levels declined significantly postoperatively, as did hemoglobin A1C and fasting glucose values. Very few small randomized controlled trials compared the effects of one surgical bariatric procedure versus another. Comparison between laparoscopic sleeve gastrectomy and laparoscopic adjustable gastric banding for morbid obesity: a meta-analysis. The system consists of an ergonomic, flexible fastener delivery device and sterile polypropylene fastener implants. The device is introduced into the body through the mouth under endoscopic visualization. Non-resorbable polypropylene fasteners are then deployed across the fold to hold the tissue in place. According to the manufacturer, the StomaphyX™ procedure is incisionless, adjustable, and revisable. It is usually performed as an outpatient procedure, and is intended for individuals who want an alternative to invasive weight loss surgery, or those who have had previous gastric bypass surgery and are regaining weight.

Additionally, not all patients respond to these therapies (Zagol 2011, Stefanidid 2010). Have extra-esophageal manifestations (asthma, hoarseness, cough, chest pains, aspiration). With fundoplication, the gastric fundus is wrapped around the lower end of the esophagus to reduce gastric reflux. Studies suggest that approximately 90% of patients who undergo Nissen fundoplication achieve symptom relief. Transoral incisionless fundoplication using the EsophyX device (EndoGastric Solutions, Inc. The EsophyX device is inserted transorally, under direct endoscopic visualization, into the stomach and is positioned at the junction of the stomach and the esophagus. Once positioned, the device uses suction and transmural fasteners to facilitate the recreation of the esophageal gastric valve. The result is an omega shaped valve 3-5 cm in length and 200-300° in circumference. As this procedure is incisionless and can often be performed on an outpatient basis it is an attractive alternative to conventional surgical procedures (Jafri 2009, Louis 2010). There is insufficient published evidence to determine the efficacy and safety of the InScope™ Tissue Apposition System for endoscopic gastric sutures.

Antireflux transoral incisionless fundoplication using EsophyX: 12-month results of a prospective multicenter study. Obesity leads to substantial morbidity, lower social functioning and quality of life, as well as premature mortality. It is associated with development and /or aggravation of many chronic conditions including cardiovascular diseases, hypertension, type 2 diabetes mellitus, sleep apnea, some forms of cancer, depression, and osteoarthritis (Duval 2006, Ogden 2006, Sturm 2007, Flegal 2012). Diet, behavioral modification, and exercise are the primary recommended treatments for obesity, but were found to have limited success among the morbidly obese. Drug therapy may be indicated for some, but has its side effects, and the majority regain the lost weight over time. Bariatric surgery is considered as an alternative therapy for morbidly obese individuals. Studies showed that bariatric surgery was more effective than behavioral and medical therapy, had long-term control of obesity, and improved comorbidities as type 2 diabetes. However, surgery is a major intervention and may be associated with risk of complications and perioperative mortality. The morbidly obese individuals usually have a higher incidence of co-existing medical problems and are more likely to develop short and long-term complications after bariatric surgery (Karamanakos 2008, Almogy 2004, Fuks 2009). It was intended to achieve a significant weight loss prior to performing a more restrictive and malabsorption operation among those at high surgical or anesthesiologic risk. After a period of initial weight loss, the surgical risk would be reduced, and the second definitive surgery could be performed. Sleeve gastrectomy is a purely restrictive operation with no malabsorptive effects. It involves removing the fundus and greater curvature portion of the stomach leaving a narrow tubular stomach that is approximately the size and shape of a banana. It preserves the integrity of the pylorus and does not include intestinal bypass as part of the technique. The technique is simple, but some components of the surgery can result in serious complications if not performed correctly (Peterli 2009, Gill 2010, Brethauer 2011). Hormonal change represented by the decrease in the ghrelin level due to resection of the fundus may be another factor for the weight loss, as well as the accelerated gastric emptying, and the behavioral © 1999 Kaiser Foundation Health Plan of Washington. Back to Top Date Sent: 3/24/2020 99 these criteria do not imply or guarantee approval. The exact underlying mechanism is still unknown, and the long-term effects of the surgery are still under investigation (Rubin 2008, Akkary 2008, Moy 2008, Karamanakos 2008, Brethauer 2011). It can also be performed in patients with disorders which preclude intestinal bypass. However, the procedure is irreversible and has potential complications associated with the relatively long staple line such as bleeding and leakage. It may also result from mid-sleeve stenosis due to stenosis in the lumen or twisting or kinking of the sleeve at the incisura. Other reported complications associated with the sleeve gastrectomy include pulmonary embolism, subphrenic abscess, liver failure, stricture, wound infection, and need for reoperation. On the long-term, sleeve gastrectomy may potentially lead to gastroesophageal reflux disease due to an increase in the gastric pressure associated with the procedure (Moy 2008, Fuks 2009, Brethauer 2011). The First Report form the American College of Surgeons Bariatric Surgery Center Network indicates that obesity is a life-long disease, and thus short-term safety and efficacy of bariatric surgery should not be the deciding factor for selection of the procedure, and long-term follow-up beyond 1 year is needed; more importantly 5 years or longer. The report also notes that specifically longer-term assessment of the sleeve gastrectomy is critical as the gastric pouch enlargement over time may limit its ultimate effectiveness (Hutter 2011). In addition, there was no standardized technique for performing sleeve gastrectomy, no standardized size or design for the gastric sleeve, and no optimal dilator size to create the lesser curvature conduit.
