The manner in which a patient breathes is adapted to the method requiring the least work of breathing symptoms quad strain 500mg glucophage sr amex. An obstructive breathing pattern, involving a prolonged inspiration (upper airway) or expiration (intrathoracic lower airways), will be observed in patients with narrowed airways. A restrictive breathing pattern, involving shallower but tachypneic breathing, will be observed in pleural disease or reduction of lung compliance. Auscultation is a valuable skill in early detection and detection of change in lung states. Stertor (snoring), wheezes (whistling), and stridor (high pitched noise) can indicate different upper airway issues. Cardiogenic pulmonary edema often begins near the heart (perihilar region), and aspiration pneumonia often originate in the cranioventral lobes. Absence or decrease in lung sounds in the caudal and ventral fields may indicate pleural effusion, while dorsal fields may be due to pneumothorax. While abnormalities in auscultations do not lead to a diagnosis, it serves as an indication for further diagnostics. If pleural space issues like pleural effusion or pneumothorax is suspected, performing thoracocentesis to evacuate the fluid or air can provide diagnostic information and therapeutic treatment simultaneously. Laryngeal paralysis is a common in older, larger breed dogs, with a higher prevalence in males. A loss in innervation of the cricoarytenoideus dorsalis muscle leads to atrophy, preventing the arytenoid cartilage from being abducted. Causes may be congenital, or be due to trauma, neuromuscular disease, neoplasia, hypothyroidism, or idiopathic. Affected dogs exhibit inspiratory stridor, exercise intolerance, ptyalism, and a change in their bark. Laryngeal paralysis can cause severe respiratory distress and collapse depending on severity. Medical management may be possible with the goals of minimizing stress, excitement, and exposure to high environmental temperature. Surgical treatment is most effective, involving unilateral lateralization of the arytenoid cartilage, or laryngeal tie-back. Cats rarely present with laryngeal paralysis, though a study suggests laryngeal paralysis a differential for cats with dyspnea, inspiratory stridor, coughing/gagging, or a change in voice, with complete resolution through unilateral lateralization. Brachycephalic syndrome results from anatomical abnormalities seen in brachycephalic breeds leading to upper airway narrowing or obstruction. Stenotic nares, elongated soft palate, and a hypoplastic trachea provide a narrowed airway and force the animals to create larger negative pressure to breath adequately. A further increase in negative pressure may evert the laryngeal saccules and collapse the larynx or trachea. Pulling of air through the narrowed airways can further cause inflammation and edema, placing the patient in further respiratory dysfunction. Surgical intervention through widening of the nares, resection of the soft palate and everted laryngeal saccules is the recommended treatment. Upper airway obstruction can also occur due to lodging of a foreign body, neoplasia, or the formation of nasopharyngeal polyps. Any upper airway dysfunction or obstruction can lead a patient to present with respiratory distress. Secondary complications such as non-cardiogenic pulmonary edema, heat stroke, and aspiration pneumonia may be seen. Pulmonary Edema Pulmonary edema is a common cause of respiratory distress in dogs and cats. Accumulation of extravascular fluid occurs in the alveoli and pulmonary parenchyma due to increased hydrostatic pressure or increased permeability in the pulmonary vasculature. The reduced oxygenation is due to a ventilation-perfusion mismatch (V/Q mismatch) because the presence of fluid in the alveoli leads to compromised ventilation. Left sided heart failure can lead to pulmonary hypertension, causing cardiogenic pulmonary edema. In cardiac disease, fluid retention and an increase in blood volume is seen as a compensatory mechanism for lowered cardiac ouput. The chronic increase in blood volume leads to an increased hydrostatic pressure (because of congestion) in the pulmonary vasculature, resulting in pulmonary edema. Patient with cardiogenic pulmonary edema may show signs of coughing, exercise intolerance, and may have a heart murmur. An echocardiogram may be performed to confirm cardiac disease and pulmonary hypertension. Fluid volume overload through fluid therapy is a possible cause of cardiogenic pulmonary edema, especially in patients with cardiac or kidney disease. Both cardiac and kidney disease can be asymptomatic, so patients on fluid therapy should be closely monitored for signs of fluid overload. Non-cardiogenic pulmonary edema can occur because of increased permeability within the lung tissue through damage to the microvasculature or alveolar epithelium. Electrocution, seizures, strangulation, pulmonary thromboembolism, and chemical exposure are all potential causes. Patients with pulmonary edema are treated with oxygen supplementation to alleviate hypoxemia and improve oxygen delivery. An arterial blood sample and a blood gas analyzer are required to obtain a PaO2 measurement. Placement of an arterial catheter, if possible from a patient stress level and staff technical skill level standpoint, is beneficial in serial monitoring of PaO2. Medical management of the cause of pulmonary edema is warranted in conjunction with respiratory support. Diuretics are administered to reduce pulmonary capillary pressure and reduce preload through reduction of blood volume. In addition to its diuretic effect, furosemide may have further beneficial effects of pulmonary vasodilation and bronchodilation. Hemoconcentration resulting from reduced intravascular volume increases the plasma colloid osmotic pressure, helping the removal of fluid from the alveoli. Nitroprusside and glycerol trinitrate are vasodilators used as additional methods in reducing hydrostatic pressure. Bronchodilators such as terbutaline may also be used, and fluid therapy restricted. Chances of resolution depend heavily on the cause, and treatment for the specific underlying disease is required. Pleural Space Disease When the pleural space, which normally serve as a potential space to create negative intrathoracic pressure during breathing, is filled with material which normally do not exist, normal breathing is compromised. The pleural space being occupied by these abnormal substances will cause the lunges to collapse and prevent adequate inflation, leading to a decrease in tidal volume, total vital capacity, and functional residual capacity. The lung volumes lead to hypoventilation, which can result in hypoxemia and hypercapnia. Hydrothorax, or accumulation of transudate can be a result of reduced plasma colloid osmotic pressure, increased hydrostatic pressure, increased vascular permeability, or neoplasia. Causes include bacterial infection due to migrating inhaled foreign objects, penetrating trauma to the chest wall, pneumonia, migrating plant material, and iatrogenic causes. Patients with pyothorax are typically treated with supportive care, antimicrobial therapy, and chest tube placement for intermittent lavaging with physiologic saline. In some cases, surgical exploration of the chest cavity to remove the source of the infection may be chosen. Potential causes include cardiomyopathy, congestive heart failure, pericardial disease, thoracic duct obstruction or rupture, lymphosarcoma, thymoma, and lung lobe torsion. Patients with chylothorax are typically managed by removal of the effusion through thoracocentesis. Hemothorax can result from coagulopathy, trauma, neoplasia, lung lobe torsion, pulmonary thromboembolism, and thymic hemorrhage. Iagtrogenic causes are also possible, from procedures such as thoracocentesis, thoracostomy, and intrathoracic biopsy. Closed pneumothorax can occur due to damaged lung parenchyma, trachea, airway, esophagus, mediastinum, or diaphragm. Traumatic pneumothorax is the most common type of pneumothorax, caused by blunt force trauma such as automobile accidents or falling from heights. Gradual accumulation of air and pressure due to the lesion acting as a one-way valve results in a tension pneumothorax. A tension pneumothorax is life-threatening; increased intrathoracic pressure causes cardiovascular depression through reduction of venous return, leading to shock. Immediate thoracocentesis, and in persistent tension pneumothorax, a thoracostomy tube may be placed to continuously evacuate air out of the chest cavity. The patient is monitored for subsequent occurrences of dyspnea, indicating a return of pneumothorax. If a closed pneumothorax does not resolve in 3-5 days, surgical exploratory is warranted. Autologous blood patch, or instilling of fresh whole blood collected from the patient into the pleural space encouraging sealing of the source of the air leak is performed for persistent pneumothorax. The degree of dyspnea varies depending on the degree of herniation, presence of concurrent pleural effusion, and presence of thoracic injuries. Surgical treatment is warranted when diaphragmatic hernias are seen, and should be performed immediately if any organ torsion or strangulation is suspected. Pneumonia Pneumonia is the inflammation of the pulmonary parenchyma caused typically by an infectious agent which enters the airway. In an emergency and critical care setting, aspiration pneumonia, caused by inhalation of contaminated material leading to an infection. Patients with aspiration pneumonia may present in respiratory distress and exhibit signs like coughing, weakness and collapse, pyrexia, cyanosis, and purulent nasal discharge. Treatment will consist of antimicrobial therapy, oxygen therapy and mechanical ventilation if necessary. Nursing interventions such a nebulization and coupaging may be instituted, though human evidence relating to a faster recovery from pneumonia has not been seen. Oxygenation A physical sign seen in patients with severe hypoxemia is cyanosis, or a blue color to the mucous membranes. Cyanosis becomes apparent when there is more than 5 g/dL of deoxyhemoglobin present in the blood. An average hemoglobin level in dogs is approximately 13-17 g/dL, and in cats is approximately 10-14 g/dL. This means the oxygen saturation of hemoglobin will be a significantly decreased level on average of 61-70% for dogs and 50-64% for a cat before cyanosis is seen. Oxygenation can be better gauged through measurement of PaO2, serving as an indicator of pulmonary function. PaO2 can be measured through blood gas analysis of arterial blood, requiring arterial blood sampling and a blood gas analyzer. A patient with normal respiratory function breathing room air will have a PaO2 of 80-100mmHg. PaO2 of less than 80mmHg qualifies as hypoxemia, and 60mmHg is considered severe hypoxemia. Pulse oximetry allows non-invasive measurements of the percentage of oxygenated functional hemoglobin in the arterial bloodstream, utilizing the concept of light absorption. The saturation of oxygen measured by pulse oximetry (SpO2) closely reflects SaO2 and can be used to estimate the PaO2 level. The oxygen-hemoglobin dissociation curve expresses the relationship between SaO2 and PaO2. Pulse oximetry has its limitations, including false reading in the presence of significant levels of dysfunctional hemoglobin species (methemoglobin, carboxyhemoglobin), inconsistent readings with movement, poor perfusion, anemia, and pigmented skin. This effect is called respiratory acidosis and respiratory alkalosis, respectively. In metabolic acidosis, compensatory increase in respiratory effort and hyperventilation is often seen, countering the metabolic acidosis effect with respiratory alkalosis. This occurs because the presence of hydrogen ions will stimulate the respiratory center of the brain to increase respiratory efforts. These cases identify key pathologic states potentially contributing to severe disease and decompensation in these patients. Since that time, the virus has spread across the country, with several cities within the United States becoming epicenters of the pandemic. We report here on the cardiopulmonary findings of the first four autopsies of a series of twelve performed on patients within the United States, with relevant implications for the treatment of severe cases. Brief Clinical Summary: the four decedents included male and female patients, ages 44-76.

It is divided into three segments angiographically: A1 (horizontal or precommunicating) symptoms diabetes type 2 order glucophage sr 500 mg without prescription, A2 (vertical or postcommunicating) treatment 4 sore throat purchase glucophage sr online pills, and A3 (distal and cortical branches) treatment effect cheap glucophage sr 500 mg without a prescription. It then travels forward and rostrally within the interhemispheric fissure medicine descriptions cheap glucophage sr 500mg overnight delivery, lying on the medial surface of the hemisphere close to the corpus callosum (Figures 49 treatment action campaign order 500 mg glucophage sr overnight delivery. The orbital or orbitofrontal artery arises proximally symptoms 4 weeks glucophage sr 500mg with visa, where the main trunk turns upward, and spreads out over the orbital surface of the frontal lobe, supplying the olfactory lobe, gyrus rectus, and medial and inferior portions of the orbital gyri. Near the genu of the corpus callosum, the frontopolar artery arises to supply the medial surface of the prefrontal region as far forward as the frontal pole. Large arrows indicate the vascular watershed or border zone between the anterior and middle cerebral arteries. It supplies the lower part of the head of the caudate nucleus, the lower part of the frontal pole of the putamen, the frontal pole of the globus pallidus, the adjacent frontal half of the anterior limb of the internal capsule, and the anterior portions of the external capsule and lateral ventricle. The anteromedial group of central arteries arises from the anterior cerebral and anterior communicating arteries and supplies the anterior hypothalamus, including the preoptic and suprachiasmatic regions, the genu of the corpus callosum, the septum pellucidum, the anterior pillars of the fornix, and part of the anterior commissure. It is divided into four segments angiographically: the M1 (horizontal), M2 (insular), M3 (opercular), and M4 (cortical branches). After giving off the posterior communicating artery, it turns laterally (its M1 segment) and along this segment gives off the lenticulostriate arteries (Figures 49. These pierce the anterior perforated substance and supply all of the putamen except for its anterior pole, the upper part of the head of the caudate nucleus and all of its body, the lateral part of the globus pallidus, and the posterior part of the anterior limb, the genu, and the anterior third of the posterior limb of the internal capsule. The lenticulostriate arteries are the vessels most often involved in hypertension-induced fibrinoid necrosis, leading to either occlusion (lacunar stroke) or hemorrhage. The anterior temporal artery curves out of the sylvian fissure and runs over the temporal lobe to supply the temporal pole and the anterior third of the superior and middle temporal gyri. The orbitofrontal artery supplies the lateral part of the orbital surface of the frontal lobe, the lateral surface of the orbital gyri, and the lateral surface of the inferior frontal convolution. The prerolandic artery runs for a short distance in the central fissure and then curves over the precentral gyrus to enter the precentral fissure, supplying the lower and anterior portions of the precentral gyrus and the posterior portions of the middle and inferior frontal convolutions. The rolandic artery runs over the opercular part of the postcentral gyrus and then enters the central sulcus; it supplies the posterior portion of the precentral gyrus and the anterior portion of the postcentral gyrus. The anterior parietal artery curves over the opercular portion of the parietal lobe and extends to the interparietal fissure, supplying the posterior border of the postcentral gyrus and the anterior parts of the other parietal convolutions. The posterior temporal artery descends from the sylvian fissure and supplies the posterior two-thirds of the superior and middle temporal convolutions. The posterior parietal (supramarginal) artery arises near the end of the sylvian fissure and supplies the supramarginal gyrus and the posterior part of the inferior parietal lobule. These enter the pia mater where they form a superficial plexus of anastomosing vessels; from these plexuses, smaller terminal branches enter the brain substance at right angles. These anastomotic branches create a collateral blood supply that can compensate to a variable extent for occlusion of a particular vessel. The two vertebral arteries enter the skull through the foramen magnum and run upward along the clivus. The vertebral artery is divided into four segments angiographically: the V1 (extraosseous), V2 (foraminal), V3 (extraspinal), and V4 (intradural). The medulla receives its blood supply from the vertebral arteries, the pons from the basilar, and the midbrain from the basilar and proximal posterior cerebrals (Figures 49. Although there is some normal variability, the right vertebral artery arises from the right subclavian and the left usually comes off the aortic arch proximal to the origin of the left subclavian artery. The relationship of the left vertebral to the subclavian is important in the pathophysiology of the subclavian steal syndrome. The left is most often dominant; it is not uncommon for the right to be significantly smaller and occasionally completely atretic. The vertebrals ascend in the foramina transversaria of the transverse processes of the cervical vertebrae from C6 to C2, giving off muscular branches. At the craniocervical junction, they escape from the upper transverse foramina and form a loop before entering the skull through the foramen magnum. The two arteries converge as they climb the clivus anterior to the hypoglossal rootlets, and then meet to form the basilar at the level of the pontomedullary junction. Just prior to joining, each vertebral gives off an anterior and a posterior spinal artery. The anterior spinal arteries join at the midmedulla and descend to supply the lower medulla, cervicomedullary junction, and upper spinal cord; the posterior spinal arteries remain separate. The anterior spinal arteries supply the pyramids, medial lemniscus, and emerging hypoglossal fibers. The basilar gives rise to three sets of vessels: paramedian perforators, short circumferential, and long circumferential arteries. The paramedian perforators are small arteries that arise from the main trunk of the basilar and dive deeply into the substance of the brainstem to supply the midline structures. The short circumferential arteries are larger vessels that supply slightly more lateral areas. Various brainstem vascular syndromes are related to disease of these different arteries (see Chapter 21). It supplies the inferior cerebellar peduncle, the dorsolateral medullary tegmentum posterior to the inferior olive and lateral to the hypoglossal nucleus, and the inferior surface of the vermis and adjacent cerebellar hemisphere. It supplies the lateral tegmentum of the upper medulla and lower pons, the inferior cerebellar peduncle, lower portion of the middle cerebellar peduncle, flocculus, and inferior surface of the cerebellar hemisphere. The posterior choroidal arteries encircle the cerebral peduncle and give off branches to the midbrain, the tela choroidea and choroid plexus of the third ventricle, and the superomedial surface of the thalamus. The posteromedial arteries, derived from the posterior communicating artery as well as the posterior cerebral, supply the hypophysis, infundibulum, tuberal and mammillary regions of the hypothalamus, walls of the third ventricle, medial and anteromedial portions of the thalamus, subthalamic structures, tegmentum of the midbrain, red nucleus, and medial portion of the cerebral peduncle. The posterolateral, or thalamogeniculate, arteries supply the caudal half of the thalamus, the posterior portion of the internal capsule, the superior cerebellar peduncle, the superior colliculus, and the geniculate bodies. Small collateral vessels enter the pia mater, where they form a superficial plexus of anastomosing vessels; from these plexuses, smaller terminal branches enter the brain substance at right angles. Because of these terminal anastomoses between larger cortical arteries, blood supply from neighboring branches may compensate to a variable extent for a vascular occlusion. The vessels themselves can be examined by conventional angiography or by digital subtraction techniques employing arterial or venous routes. Doppler and other ultrasonic tests detect the presence of occlusions or stenoses in the large neck vessels in a noninvasive manner, and transcranial Doppler studies help with evaluation of flow in the intracranial vessels. Magnetic resonance imaging provides evidence of cerebral infarction in various vascular territories. Diffusion and perfusion weighted imaging provide immediate evidence of focal ischemia. They may be divided into an external, superficial, or cortical group, and an internal, deep, or central group (Figure 49. The external veins arise from the cortex and medullary substance of the hemisphere. The superior cerebral veins, 8 to 12 in number, drain the superior, lateral, and medial surfaces of the hemispheresPthomegroup above the sylvian and callosomarginal fissures. Most of them are lodged in the sulci between the gyri, although some of the larger trunks run across the convexity of the gyri. The arrangement on the two sides is asymmetric, and a separation into anterior and posterior groups is usually evident. The larger posterior veins drain the parietal region and run forward before entering the sinus; some from the convex surface of the occipital lobe may terminate in the transverse sinus. The inferior cerebral veins are small and drain the basal surfaces of the hemispheres and the lower portion of the lateral surfaces. Those from the temporal lobes anastomose with the middle cerebral veins and enter the cavernous, sphenoparietal, transverse, and superior petrosal sinuses. The middle cerebral vein traverses the sylvian fissure and drains the insula and the opercular region. It terminates either in the cavernous or sphenoparietal sinus or occasionally in the transverse or superior petrosal sinus. The choroidal vein runs the entire length of the choroid plexus and receives branches from the hippocampus, fornix, and corpus callosum. The terminal vein runs in the groove between the caudate nucleus and thalamus and receives many tributaries from these structures as well as from the internal capsule. Near the interventricular foramen, the terminal and choroidal veins fuse to form the internal cerebral vein. The great cerebral vein of Galen is formed just behind the pineal body by the union of the two internal cerebral veins. It is a short midline trunk that curves backward and upward around the splenium of the corpus callosum and empties into the straight sinus. The deep venous system is the entire territory served by the great vein of Galen and the basal veins. A venous watershed exists between the territories of the deep and superficial venous systems. The venous sinuses of the dura mater are channels that lie between the two layers of the dura; the cerebral veins terminate in them (Figure 49. In its middle portion, it gives off a number of lateral diverticula, or venous lacunae, into which protrude the arachnoid (pacchionian) granulations. The inferior sagittal sinus is located in the posterior half or two- thirds of the free, inferior margin of the falx cerebri, and receives veins from the falx and from the medial surfaces of the hemispheres. The straight sinus receives, in addition to the inferior sagittal sinus, the vein of Galen and the superior cerebellar veins. The occipital sinus begins at the margin of the foramen magnum and courses through the lower attached margin of the falx cerebri to the transverse sinus. The superior sagittal, straight, and occipital sinuses come together at the confluence of sinuses (torcular herophili). The transverse (lateral) sinuses begin at the confluence of sinuses and pass laterally and forward in the attached margin of the tentorium cerebelli to the petrous portion of the temporal bone. They then pass downward and medially to reach the jugular foramen where they end in the internal jugular veins. The portions occupying the groove on the mastoid part of the temporal bone are sometimes called sigmoid sinuses. The transverse sinuses receive blood from the superior petrosal sinuses, inferior cerebral and inferior cerebellar veins, and emissary and diploic veins. The cavernous sinuses lie on each side of the body of the sphenoid bone, lateral to the sella turcica, and extend from the superior orbital fissure to the petrous portion of the temporal bone. The cavernous sinuses receive the ophthalmic veins, some of the cerebral veins, and the small sphenoparietal sinus that courses under the surface of the small wing of the sphenoid bone. The two sinuses communicate with each other by the anterior and posterior intercavernous sinuses. The superior petrosal sinus connects the cavernous with the transverse sinus and receives cerebellar and inferior cerebral veins and veins from the tympanic cavity. The inferior petrosal sinus connects the cavernous sinus with the internal jugular vein and receives the internal auditory veins and veins from the cerebellum and medulla. The basilar plexus consists of several interlacing venous channels between the layers of the dura mater on the basilar part of the occipital bone; it connects the two inferior petrosal sinuses and communicates with the vertebral venous plexuses. Emissary veins pass through apertures in the cranial wall and establish communications between the sinuses inside the skull and veins external to it. Diploic veins occupy channels in the diploe of the cranial bones and communicate with the sinuses of the dura mater, veins of the pericranium, and meningeal veins. Veins draining the pons and midbrain go cephalad into the basal vein, great cerebral veins, cerebellar veins, or the petrosal or transverse sinuses. Consequently, compression at either the foramen magnum or the tentorium may cause bleeding into the brainstem. A significant asymmetry may signify brachiocephalic occlusive disease on the side with the lower pressure. High-grade stenosis or occlusion may produce a palpable delay or loss of volume of the brachial or radial pulse on the involved side. Gentle and cautious palpation of the carotid pulse in the neck may give some information about the patency in certain cases. By careful palpation either low in the neck or just below the mandible, it may be possible to distinguish between common and internal carotid pulsations. Diminished, unequal, or absent pulsations may indicate either partial or complete obstruction. There is some risk to carotid palpation, and the useful information obtained is limited. Occlusive disease of the common carotid may cause decreased facial pulses on the involved side. Evaluation of the peripheral pulses in the lower extremities may reveal evidence of generalized vascular disease. Bruits heard over the carotid artery bifurcations in the neck, over the common carotids proximally, or in the supraclavicular fossae usually signify occlusive vascular disease, but the correlation between bruits and carotid occlusive disease is imprecise. Bruits may be heard diffusely in some patients, particularly those with a hyperdynamic circulation or increased cardiac output. In older patients and those with symptoms of vascular disease, diffuse or localized bruits, unilateral or bilateral, are equally predictive of moderate-to-severe atherosclerosis in the extracranial carotid artery. Severe occlusive disease with high-grade stenosis may cause only a very soft, short, unimpressive systolic bruit because of the severely restricted flow through the stenotic vessel. A very high-pitched, whistling bruit is a fairly reliable indicator of severe underlying stenosis.

After receiving a home visit to plan initial therapy and load software/loan computer equipment with the first set of therapy exercises medications zithromax buy glucophage sr 500mg on-line, all treatment was carried out remotely treatment variable purchase glucophage sr canada. Patients completed exercises and sent these to the therapist via the Internet symptoms 7dpo purchase glucophage sr without prescription, who set further exercises for completion medicine ads quality glucophage sr 500 mg. This cycle continued for 3 months treatment spinal stenosis generic glucophage sr 500 mg with visa, after which time a face-to-face assessment was completed symptoms 7dp3dt order glucophage sr master card, followed by 3 further months of therapy. In terms of acceptability, the patients found this remote delivery of therapy a very positive experience. Wade, J (2003) et al interviewed 6 of the 7 patients who took part in the Mortley (2004) study to examine their experience of delivery of therapy in more detail. Partners valued the fact that the software could be used without them being present. Partner involvement during use of the computer varied with one partner being present all the time, one not at all and 4 in between. Despite the lack of face-to-face contact, all participants perceived the role of the therapist as crucial. Participants listed a number of effects of therapy including increased ability on therapy tasks, positive effects on conversation and phone/computer skills. Participants expressed anxiety about cessation of therapy, with two believing they needed constant practice to stop deterioration. Patients attended 15 weeks of computer-assisted therapy facilitated by a speech and language therapist. All of the study participants (mild to moderate anomia) demonstrated improvement in their naming skills. This therapy saved a lot of therapist time, 2 hours therapist time per month was provided in the intervention as compared with around 12 hours for others. However, it is important to remember this computer based therapy was tailor-made for each patient and there was still regular contact with the therapist. In addition, all 7 patients were motivated to take part in the study and over half had previous experience with computers. The study lasted for 12 months and 20 of the 39 participants completed all outcome measures when the study ended. Support was provided through a structured programme of real-life goal setting individually or in groups, provision of information and help to access other services. The evaluation utilised quantitative and qualitative methods to consider the experiences and outcomes for the participants. Significant gains were in quality of life particularly in relation to communication and psychosocial adjustment to stroke. Real-life goals were set for each participant during the intervention and 82% were fully or partially achieved. Best (2008) investigated impairment-based therapy for anomia in 8 people with aphasia. After 2 baseline assessment participants received two phases of therapy, each phase lasted for 8 weeks. Spoken and written cues to help with word finding were utilised in the first phase and the later phase encouraged participants to use targeted words in connected speech and conversation with their conversation partner. Participants were also assessed 8 weeks after the end of the second therapy phase. Additionally, the 8 participants all rated their participants in activities needing conversation as higher at the end than start of the intervention. The findings from this small study suggest that impairment-based therapy for aphasia can increase participation in activities for people with aphasia. Best (2011) investigated changes in conversation for patients with aphasia following therapy in anomia. The patients as a group significantly improved their scores on the picture naming task after the therapy compared to baseline assessment. The study concluded that although further research would be required to assess the effectiveness of the therapy the findings are promising. There were no significant changes in the conversational variables assessed following the therapy for the group although some individuals did experience changes. Improvements were around changes in noun retrieval in conversation and the number of nouns produced in the 5 minutes of conversation analysed. These promising findings suggest that the improvement in picture naming following therapy can possibly lead to changes in retrieval of noun in conversation. Snell (2010) examined the optimum number of words provided in naming therapy for people with aphasia. Additionally, the study attempted to discover if severity of aphasia should determine the size of the set of words to be learnt. There was large variation, 5 to 120 words, in the number of treated words in the 21 studies with very different learning outcomes not linked to number of treated items. Additionally, in the current literature more items were given to patients with severe aphasia, this did not reflect clinical practice. The results of the meta-analysis were unable to conclusively answer the two study questions resulting in a cross-over case-series study to address them. Thirteen people with anomia were investigated in the study and therapy with a small set of words (20) was compared with therapy with a larger set of words (60). Twelve of the 13 participants learned a greater number of words when treated with the larger set. Anomia severity did not correlate with set size although it did with learning performance. Findings from this study indicate that larger therapy sets could potentially be used in therapy for people with aphasia. However, current therapy generally uses less words and the time taken to develop the sets and train them would need to be considered in determining feasibility. A further study considers the impact of using images relevant to the individual with aphasia. The software consists of an empty vocabulary that can be filled with items that are personally relevant for each individual. The therapist and client chose relevant vocabulary using pictures, drawings, photos and text. This vocabulary can be used to create messages which are displayed by the device, with or without speech output. Twenty-two aphasic patients with relatively good auditory comprehension and limited verbal expression took part in the study. Following training, all 22 participants could operate the device in the therapy sessions. Van de Sandt-Koenderman, M (2007) undertook a further study investigating the efficacy of the TouchSpeak system in improving outcomes. Thirty-four individuals with severe aphasia were given 12 hours vocabulary training over 10 weeks. The training focused on using the vocabulary of the device in specific day-to-day situations and included role play sessions and time to practice at home. Following training, around half of the participants could navigate the complete set of 176 buttons on the device. User satisfaction was high with 70% of patients, 74% partners and 68% therapists rating TouchSpeak as good, very good or excellent. Seventeen participants decided to purchase their own device with TouchSpeak installed. Reasons for non-use were that communicative ability had improved; there were technical problems or the patient had a preference for other communicative strategies. Delivery and Format of Therapy the delivery of therapy was looked at in one study in which an intervention delivered to a group was examined. The remaining studies looked at the efficacy of different types of aphasia therapy. Elman, R (1999) examined the effects of treatment delivered in a group format for individuals with chronic aphasia. Twenty-eight aphasic individuals were assigned to an immediate or deferred treatment group. The immediate treatment group received 5 hours of group communication weekly for four months in the form of 2 and a half hour sessions on 2 days. Participants were split into groups of 7 according to severity of aphasia to enable matching with similar patients. The deferred treatment group first received 3 hours or more per week of social group activities of their choice, for example, art groups or support groups before receiving the group communication treatment intervention. The immediate treatment group scored much higher than the deferred treatment group on all measurements, with no decline in the follow-up period. The deferred group showed similar gains once they had received the group treatment intervention. Worrall, L (2000) designed and evaluated a functional communication therapy programme called Speaking Out. Twenty aphasics, 12 months post-stroke, who had difficulty in daily communication took part in the study. The Speaking Out programme consisted of 10 scripted modules covering topics such as managing finances, starting a conversation and using the telephone. Finally towards the end, participants and volunteers planned some actions that could be undertaken on the topic. Groups received either the Speaking Out programme first or took part in recreational activities (such as cards, crafts and gardening) for 1-2 hours per week over 10 weeks. At the end of this period, participants were assessed using a set of measures that were also administered at the beginning of the study. Pre and post receiving the Speaking Out programme, both groups improved on the Western Aphasia Battery (ability to point to correct objects). In terms of significant improvements in conversation, Group B did show improvement following Speaking Out but Group A did not. However following the recreational activities, some of these improvements were also seen- indicating a possible placebo effect. Barthel, G (2008) investigated the therapy effects of two types of intensive speech language therapy for aphasic individuals. All patients received 30 hours of their designated therapy mode within 2 weeks in sessions lasting 3 hours per day. Errorless therapy attempts to control errors made during therapy whereas errorful therapy does not attempt to control errors. In previous studies no difference in outcomes had been found between errorful and errorless therapy. The study was repeated a third time with slight modifications to the therapies administered. Seven patients who had word finding difficulties as a result of aphasia took part in the investigation. Errorful therapy consisted of providing a picture with the first phoneme and grapheme and asking the patient to name the picture. During errorless therapy, patients were given a picture with its written and spoken name. Each therapy session included 3 cycles of the items/pictures, which lasted around 25-40 minutes. As found in the previous studies, errorless and errorful therapy produced equivalent results immediately post-therapy and follow-up. Non- language cognitive skills, for example problem solving skills and monitoring ability could predict therapy outcome. The participants received therapy in their own homes with both therapies provided in each of the sessions. There were greater gains in noun naming for the 3 participants with most severe aphasia. Similar to the Fillingham(2005) study errorless therapy was found to be as effective as errorful therapy in this small study. Aftonomous, L (1999) evaluated the outcomes for aphasic patients receiving community- based treatment programmes, to see if these were comparable with effects reported in research. Patients with a wide range of types and severity of aphasia, who were mostly 6 months post stroke, followed 2 identical treatment programmes in California and Kansas. A detailed patient care algorithm was used to determine the clinical pathway for each patient and technology that provides access to an extensive toolbox of specially designed, interactive multimedia materials for patient use. Therapists were formally trained in how to administer this treatment programme and an online database provided easy access to patient details, their diagnostic assessment and their responses to treatment.
