Pre-operative preparation A baseline neurological examination is performed and neurological scores are attributed when applicable diet during acute gastritis buy 4 mg doxazosin visa. Antiplatelet agents are highly recommended in the preparation patients undergoing intracranial stenting gastritis and exercise buy doxazosin 2mg online. As a consequence gastritis diet 4 you buy doxazosin 1mg without prescription, patients receive either a loading-dose or a period of antiplatelet therapy gastritis diet 7 day discount doxazosin 4 mg otc. A loading-dose of 300 or 600 mg of clopidogrel is then administered the day before the endovascular treatment gastritis diet 23 doxazosin 1mg. This is supported by both literature to date and previous experience in the cardiology field gastritis pain remedy order 2 mg doxazosin overnight delivery. Some authors have suggested the use of preparations of 325mg or more for three or more days before the procedure gastritis and duodenitis definition 1 mg doxazosin fast delivery, concomitant with clopidogrel gastritis symptoms months buy 4 mg doxazosin fast delivery. This presents the advantage of avoiding the use of double antiaggregation in the pre-operative period, in which the aneurysm is not yet secured. Little data is available specifically for patients undergoing stent-assisted treatment of intracranial aneurysms, but thromboembolic adverse events do seem highly concentrated in the low responder group. Some authors have consequently recommended a level of at least 40% of platelet inhibition. Stent-Assisted Techniques for Intracranial Aneurysms 295 Individual response to clopidogrel may be evaluated using different techniques. Recently, point-of-care assays have been commercially available, allowing practitioners to perform prompt measurements pre-operatively. In selected cases, the doses of antiplatelet agents might be adapted in order to achieve the desired levels. Another advantage of these point of-care assays is the fact that they may be performed per-operatively, so that the operator is informed of the percentage of antiaggregation at the moment of stent deployment. Such an approach requires systematic blood sampling, subsequent drug administration and financial investment. At present, no prospective study assessed the potential benefits in achieving a level of anti-aggregation over 40% in patients undergoing intracranial procedures. The same applies for the assessment of the risk of hemorrhagic adverse events that may be related to the combination of intravenous heparin and double antiaggregation. We have witnessed a proliferation of portable devices and this technology is increasingly being used, and particularly in the cardiology field. In the field of interventional neuroradiology, studies specifically focused on the importance of antiaggregation are rare. Only two have studied the incidence of thromboembolism using techniques and different cut-offs. We recently performed a study on 271 procedures in which the VerifyNow assay was used and observed a significant association between thromboembolism and poor antiagregation. The ability to predict the risk of a thromboembolic event occuring does exist, but it is moderate given the multifactorial nature of these events. In our experience, body weight should be considered as an important factor to observe. If a stent has to be deployed urgently and the patient has not been prepared with antiplatelet agents, the risk of thromboembolic events may be significant, since post-operative aspirin and clopidogrel will take time to act. This is a self-expandable device made of nitinol (nickeltitanium) wires with a braided design. Its main features are good visibility and the availability of long devices (up to 75 mm). It was the first self-expandable device specifically designed for assisting the treatment of brain aneurysms with coils. In its first version, a low radial force resulted in a number of cases of inadequate support for the coil mass within the aneurysm and technical problems such as stent migration. This newest version eliminated the need for an exchange maneuver using a 3m microguidewire. Equipped with a Neuro Renegade Hi-Flo Microcatheter for deployment (total usable length 150cm, flexible tip length 10 cm)? A major characteristic of this device is its easy placement, with good wall apposition and excellent support of the coil mass. A disadvantage of the delivery system is the absence of a very long microguidewire distal to the parent artery. In the context of very tortuous vessels, this may be a factor of instability during deployment. According to the manufacturer, the following product characteristics should be noted:? It is a nitinol self-expanding stent that can be delivered and deployed by a single operator. Available in two diameters, 4mm for vessels from 3 to 4mm, and 6 mm for vessels from 5 to 6mm. The Pharos Vitesse stent is the second generation of this balloon expandable stent for both intracranial ischemic stenosis and wide-neck aneurysm treatment. It is a rapid exchange balloon-delivered device, which enables the operator to deliver and deploy the stent in one step. According to the manufacturer, the following product characteristics should be noted: Stent-Assisted Techniques for Intracranial Aneurysms 299? Available in eight diameters: 2, 2,5, 2,75, 3, 3,5, 4, 4,5 and 5 mm, for vessels from 2 to 5 mm;? It is a hybrid closed-cell stent in nitinol with flared ends and a double helix of tantalum strands to assist full-length visualization. It presents a high metal-to surface coverage intended to help promote neo-endothelization. However, the sliding design of its cells ensures the feasibility of crossing the struts with a microcatheter. Flow diverters these are braided, tubular stents with very small struts that are intended to provide significant flow disruption along the aneurysm neck, but allow preservation of both large branches and small perforators. Such devices may reduce shear stress on the aneurysm wall 300 Aneurysm and promote intra-aneurysmal blood stagnation and thrombosis (Pierot, 2011). Besides their effects on flow, these devices also provide significant scaffolding for neo-endothelization across the aneurysm neck. They are high-cost devices and their main characteristic is the very high metal-to-artery coverage in comparison to conventional stents. Other It is worth noting that a number of stents that were not specifically designed for use with intracranial aneurysms have non-rarely been used as adjunctive devices. This situation was much more frequent in the early times of stent-assisted aneurysm embolization, when a lesser variety of devices were available. That is the case with the Jostent GraftMaster Stent Graft (Abbott Vascular, Redwood City, Calif), a balloon-mounted system consisting of two stainless steel flexible devices with an expandable layer of polytetrafluoroethylene between them. It was developed for use within the coronary circulation, particularly for cases of leakage or vessel perforation. However, cases of repair of internal carotid artery, middle cerebral artery and vertebral artery aneurysms were regularly reported with this system (Chan et al. In addition, when a stent is deployed after an aneurysm coil, significant scaffolding for neo endothelisation is provided and an increase in pack density may be observed. This technique may be particularly useful for small aneurysms, in which the introduction of a microcatheter and repetitive manipulations may be dangerous. The coil is deployed first and then a preloaded stent is released, pushing the coil loop into the sac. When non-assisted coiling is performed, coil migration or herniation of the coil mass may be observed, even if the neck is not very wide. If a large amount of material is present in the lumen of the parent artery, its patency may be threatened, or the patient may be exposed to a risk of embolic phenomena. Stenting and coiling: crossing a deployed stent with a microcatheter When stent-assisted coiling is performed, the microcatheter tip may be placed inside the aneurysm the through the stent struts. Placement of a microcatheter into the aneurysm is evidently more difficult after stenting, especially if a closed-cell device was used. Some practitioners prefer using a Neuroform stent in such situations, for the same reason. Furthermore, with a Neuroform stent, it is easier to regain access to the aneurysm sac in cases of microcatheter kickback into the parent vessel. If the operator experiences difficulty in penetrating the aneurysm sac, especially when the angle of penetration is not favorable, caution should be taken in order to avoid abrupt release of energy accumulated in the system, which may have disastrous consequences, especially with small or ruptured cerebral aneurysms. B, A microcatheter is introduced into the aneurysm sac through the stent struts allowing treatment with coils. However, when significant kickback occurs, it may be problematic to regain access to the aneurysm sac. Some authors argue that the previous deployment of coil loops before stent placement may be useful. The previously deployed coil may be used as a guidewire and allow reintroduction of the microcatheter in case of early kickback (Kim et al. This technique presents several advantages: the possibility to regain access to the aneurysm sac in case of kickback by a slight repositioning of the stent; the absence of blood flow arrest as observed with balloon 304 Aneurysm remodeling techniques; the possibility to chose to either retrieve or definitely deploy the stent after coiling; and the possibility of not using double antiplatelet treatment if the stent is retrieved at the end of the procedure. A microcatheter is then navigated into the other branch and a second stent is released. Another possibility is to place both stents in a parallel configuration, without crossing the first one. B, An open-cell stent is deployed into the basilar artery and right posterior cerebral artery, but is not sufficient to provide adequate protection against coil herniation or migration. A second (closed-cell) stent is placed in the basilar artery (concentric to the first stent) and left posterior cerebral artery. A microcatheter is positioned inside the aneurysm sac, which is treated with coils. Up to date, only stents from the Solitaire group may be retrieved after full deployment. It is worth noting that with this kind of stent (but not exclusive to this brand) the use of a dynamic push in the delivery wire increases notoriously the apposition to the vascular walls, an effect that is important to remember when using this device as a remodeling tool. Flow diversion Even though a large part of the deployment steps are common for the majority of intracranial stents, the technique for flow diverters differs in some details that make the method more challenging. The operator must work within a technique of pushing the delivery microguidewire forward, of pulling the microcatheter back, and pushing the entire system so that the stent opening and apposition are optimal. In addition, the phenomenon of shortening after deployment must be taken into consideration for the adequate selection of the stent length. For the Pipeline Embolization Device, adequate pushing on the microcatheter is also important to release the distal extremity of the device from the capture coil that keeps it attached to the delivery microguidewire. In addition, forward pushing may increase mesh density, and accounts for the customization that is possible with this type of device. Treatment of a cerebral aneurysm using flow diversion with a Pipeline Embolization Device. Note the higher density of the mesh near the aneurysm neck, which can be obtained with proper deployment technique. Results the morphological results on immediate and late post-operative angiograms are categorized according to the revised Raymond classification into 1 of the following groups: complete occlusion, neck remnant, and residual aneurysm. Follow-up examinations with Digital Substraction Angriography or Magnetic Resonance Angiograms are then scheduled at minimum intervals of 6, 18 and 36 months. The rates of complete occlusion differ significantly from the results observed on the immediate postoperative angiogram after stent-assisted coiling. In a recent study on the Neuroform Stent in our institution, we observed that the percentage of complete occlusion tends to stabilize after six months. However, progressive thrombosis and subsequent increase of the degree of aneurysm occlusion between the immediate postoperative and six month angiograms are observed in roughly 50% of the aneurysms treated with stent assisted techniques (Maldonado et al. However, in three years of follow-up, six aneurysms with an initial complete occlusion and five with a neck remnant recanalized. The analysis by type of coil did not demonstrate any association between complete occlusion and coil type. Endovascular treatment of a repermeabilized aneurysm of the right middle cerebral artery using the Neuroform Stent System. Stent-Assisted Techniques for Intracranial Aneurysms 309 Stents may contribute to the progression of thrombosis, independent to the size of the aneurysm and type of coils used. The overall complete occlusion rate obtained with stent-assisted coiling seems superior to results obtained with coils alone or other adjunctive devices in cases of large or complex aneurysms. Complications Recent case series report incidences of adverse events ranging from 8. Risk factors for complications are age, presence of significant atherosclerotic disease, subarachnoid hemorrhage, small aneurysm and large/giant aneurysm. The most common of those adverse events in the peri-operative phase are navigation problems, stent misplacement, stent migration, vessel dissection or perforation, and thromboembolic events. Delayed stroke due to intrastent thrombosis or intrastent stenosis are less frequent but may be observed, especially in patients with irregular use of antiplatelets. In a recent study published by the authors on 76 aneurysms treated with a Neuroform Stent-assisted technique, a five-month delayed symptomatic stroke and three clinically silent in-stent stenosis were observed. There is currently significant concern about the risk of delayed rupture after flow-diversion treatment. First, the mural thrombus may act as a source of inflammatory substances such as proteases leading to chemical degradation and weakening of the aneurysm wall. Second, flow diversion may induce changes in intra aneurysmal flow pattern with a consequent increase in stress to areas that were not previously exposed. In a series of recent international cases of rupture after flow diversion, the following risk factors seemed to be important (Kulcsar et al. After that period, only one of those antiplatelet agents is continued, for a period of time that has varied in literature from three months to indefinitely.

Chapter 15 Retroperitoneal Haemorrhage as a Dangerous Complication of Endovascular Cerebral Aneurysmal Coiling Yasuo Murai and Akira Teramoto Additional information is available at the end of the chapter dx. Introduction Retroperitoneal haemorrhage has been reported as a complication of interventional surgery in less than 3% of all interventional procedures (Ellis et al. Technical advances in neuroendovascular therapy including aneurysm coiling (Bejjani et al. However, iatrogenic complications such as haematoma or vascular dissections may still occur(Sakai et al. Although most cases of retroperitoneal haematoma are associated with blunt trauma or rupture of a diseased abdominal artery, interventional surgical accidents are another aetiology (Haviv et al. Retroperitoneal haematoma is a relatively rare but serious complication of femoral artery catheterization Bejjani et al. Interventional radiologists and cardiologists have identified the predisposing factors, typical presentation and clinical course of this iatrogenic complication (Haviv et al. However, only a small number of cases of retroperitoneal 2012 Murai and Teramoto, licensee InTech.

Post angiographic retroperitoneal haemorrhage is often difficult to diagnose (Illescas et al. We report here a case of retroperitoneal haemorrhage following endovascular coiling of a ruptured anterior communicating artery aneurysm, with emphasis on the difficulty in diagnosing retroperitoneal haemorrhage in patients with disturbed consciousness. Representative case presentation Computed tomography performed at the time of admission on a male patient who complained of headaches revealed a slight subarachnoid haemorrhage (figure 1).

In a randomized clinical trial assessing the white matter boundary ofentimes distorting the overlying gray radiotherapy alone with radiotherapy combined with concomitant and matter. Fibrillary exclusively attributable to patients with tumors with a methylated astrocytomas may appear as bare nuclei. Tese results which the nucleus is displaced by homogeneous eosinophilic suggest that treatment strategies should be individualized dependent cytoplasm, ofentimes referred to as the gemistocytic phenotype. Tumors with the 1p/19q deletion respond better to chemotherapy Microscopically: Cytological and nuclear pleomorphism may be and radiotherapy resulting in prolonged progression free survival and more pronounced. Mitotic overall survival in patients, especially with anaplastic activity distinguishes the anaplastic astrocytoma from difuse oligodendrogliomas [64,65]. In addition, the constitutively active which confers enhanced tumorigenicity on glioma proneural subtype contains several proneural development genes such cells by increasing proliferation and reducing apoptosis [74]. Subsequent phase 2 clinical trials have group who did not receive aggressive treatment [86]. This fusion event is frequently detected in pilocytic Treatment and Prognosis astrocytomas, pleomorphic xanthoastrocytomas, and malignant Although pilocytic astrocytomas commonly arise in the frst two astrocytomas [14,40]. Gross total resection of pilocytic astrocytomas provides the greatest clinical outcomes [90]. The long-term risks of radiotherapy in genetic subtypes including classical, mesenchymal, proneural, and children suggest it be employed only in cases of recurrence or pilocytic neural [86]. From therapy, and chemotherapy is used in the treatment of malignant their analysis, they identifed four risk groups in which the two lower gliomas. Surgery plays a key role in the treatment of malignant gliomas risk groups included patients under the age of 40 with the lowest as it allows for both cytoreduction and confrmation of diagnosis. The intermediate risk group included patients aged 40-65 with gross total resection is important in prolonging survival [95,96]. Only infants, young moribund children, and patients parameters serve as prognostic indicators of long-term survival. Tumor declining treatment in favor of supportive care would not be size and location are also important indicators as extent of resection is recommended to receive some form of radiation therapy shortly afer dictated not only by tumor size but also by location of the tumor. Radiation therapy alone has been shown to improve median Finally, grade of tumor is an important indicator of long term survival survival from 3-4 months to 9-12 months [97,98]. Although radiation as the higher the grade the more malignant the tumor is, which therapy has shown a clear improvement in survival for patients with directly results in a poorer prognosis. With new Treatment and Prognosis chemotherapeutic agents being developed the gold standard for evaluating these agents remain randomized clinical trials. Although overall >45 Gy [117], while in another study, no diference in 5-year survival survival was not improved in these studies, progression-free survival was observed in patients with or without postoperative radiation [118]. The presence of calcifcations on imaging as a tumor resistance through the use of multi-targeted strategies. Since metastases along the cranio-spinal axis are present in roughly 33% of patients [126], evaluation for Ependymomas are a rare type of glial tumor that is believed to arise metastases is recommended. A large portion of intracranial Classifcation and Histology ependymomas (36-60%) occur in children, making ependymomas the second most common malignant brain tumor in this population [121]. Ependymomas are usually well circumscribed and benign but they Molecular pathways: While the etiology is unknown, roughly 2-5% have been known to be invasive. Within classic is caused by inactivating mutations in the adenomatous polyposis coli ependymomas there are an additional four variants including cellular, gene [130,131]. In addition, great strides have been made in our papillary, clear cell, and tanycytic. Lastly, it is worth noting that once understanding of the oncogenesis of medulloblastomas. Based on gene considered a variant, ependymoblastoma, is now being regarded as a expression profles using tissue microarrays and substantiated using rare childhood primitive neuroectodermal tumor with abundant whole genome and whole exome sequencing, medulloblastomas have mitotic fgures and true rosettes [123]. Chromosomal Treatment and Prognosis aberrations have also been associated with this subgroup including loss Since ependymomas are highly radiosensitive, the best approach for of 9q (accounting for 21-47%), 10q, 20p, 21p and gain of chromosome treatment of ependymomas is gross total resection followed by 3q and 9p [132,136,140]. The role of chemotherapy for the treatment of occur in infants under the age of 3 and again in adults above age 16 ependymomas is currently unclear [124]. Treatment is afecting patients above 3 years old, good prognosis, and infrequent usually surgical resection. Group 3 and 4 medulloblastomas: Both of these subgroups present Medulloblastoma with common clinical features and share similar molecular profles. The age of onset for both groups vary with Group 3 peaking in Medulloblastomas are the second most frequent childhood brain childhood (3-10 years), while Group 4 has a more distributed age of tumor afer Pilocytic astrocytomas, and the most common malignant onset from infancy to adulthood [136,141]. The majority of tumors in brain tumor in children comprising roughly 25% of intracranial both groups display classical histology. They occur exclusively in the posterior fossa with a peak common to both groups with isochromosome 17q representing the incidence between 4 and 7 years [127]. Gain of 7 and 18q along with ofen present with symptoms of increased intracranial pressure loss of 8 and 11p are also common abnormalities [136,137,147]. Treatment Finally, placement of permanent ventriculoperitoneal shunts is required in 30-40% of patients afer tumor resection of the posterior If the tumor is not causing symptoms, tumor growth may be fossa [151,152]. Similar to other tumor types, extent of Prognosis tumor resection is benefcial for minimizing the risk of tumor recurrence. As a result, in 1957, Simpson established a classifcation Patients with medulloblastomas are classifed into three risk groups system consisting of fve subdivisions to assess extent of resection of that help facilitate treatment and provide predictions on prognosis. Residual tumor measuring greater complete resection of the sinus is also performed. Tese patients have a poor prognosis with a 5-year disease free without resection or coagulation of the dural attachment. Finally Simpson grade V is characterized leaving the other two groups as primary predictors. Meningiomas arise from the layer of tissue covering the brain and With advancements in surgical techniques and treatment options, spinal cord. Meningiomas are the most common benign intracranial such as radiation therapy, relying solely on the Simpson grading system tumor accounting for about 13-26% of all primary brain tumors [156]. Terefore, cell proliferation markers, such as Ki-67 occur accounting for an estimated 7. The vast majority of meningiomas rarely metastasize with a rate the Simpson grading system in predicting tumor recurrence [168]. Meningiomas rarely afect children with an index could be benefcial in planning optimal follow-up strategies with incidence rate of roughly 2. If multiple meningiomas are observed, suspicion of radiosurgery) can provide improved and durable local control in neurofbromatosis type 2 is high. Tese tumors may secrete abnormally high maximum resection and adjuvant radiotherapy have been shown to be amounts of hormones that may lead to physiological dysfunction independent predictors of patient survival and disease-free survival in resulting in patient morbidity. Evaluating stereotactic disturbances, mass efect leading to bitemporal hemianopsia is ofen radiosurgery in the setting of subtotal resection or recurrence, reported observed in patients with pituitary neoplasms. While some studies have suggested stereotactic radiosurgery is not indicated for malignant meningiomas [171], others have shown Classifcation and Histology improved local control rates of 17% at 15 months [172]. Finally, for recurrent atypical or anaplastic meningiomas not suitable for A functional classifcation scheme has been developed based upon radiosurgery, resection followed by permanent brachytherapy is a the secreted hormones and include lactotrophic adenomas potential salvage therapy that has shown promise in the clinical setting (prolactinomas) which secrete prolactin, are the most common, and [173,174]. In the largest series (n=21) to date examining brachytherapy causes amenorrhea-galactorrhea syndrome in women and impotence for therapy for the recurrence of aggressive atypical and anaplastic in men, somatotrophic adenomas which secrete growth hormone, meningiomas, Ware et al. An increased concentration of various chemotherapies in which all have been disappointing growth hormone from somatotrophic adenomas can lead to [175,176]. Interestingly, more than 95% of cases of acromegaly are analogues and interferon-? Further, emerging targeted therapies including sunitinib, may prove useful in refractory Treatment meningiomas [175,176]. Since the normal pituitary gland also enhances, the timing of the contrast is important in Prognosis for patients with benign meningiomas is generally good achieving a high-spatial-resolution image that is able to discern normal with a 5-year survival rate of 91. In patients with non extent of surgical resection with a recurrence rate of 8% in cases with a secreting tumors and without neurologically defcits, it is reasonable to gross total resection, a 29% in cases with a subtotal resection [178]. Atypical meningiomas have been reported to have a higher rate of local recurrence and are associated with lower survival rates compared to Current treatment options for symptomatic pituitary adenomas benign meningiomas [179]. Similar to benign meningiomas, achieving include surgical resection, radiation therapy and medication therapy a gross total resection of atypical meningiomas was associated with a (frst line for treating prolactinomas). Tree dopamine agonists are lower recurrence rate (11%) compared to achieving a subtotal resection routinely given to treat prolactinomas and include bromocriptine, (100%) [179]. A similar trend of increased survival is also associated carbergoline, and pergolide. Surgery using a transsphenoidal approach with (grade I) total resection of malignant mengiomas [180]. Lastly, is typically the frst line treatment for the other subtypes of pituitary Al-Mefy and colleagues investigating the malignant progression in adenomas [190,191]. Medical therapy is also used for patients with meningioma from a benign to a higher histological grade, and somatotrophic adenomas and includes dopamine agonists. Medical treatment for alterations in chromosome 22 and deletion of chromosomes (1p, 14q, thyrotropin-secreting tumors typically involves somatostatin analogues and 10q), even with a benign histological grade, may potentially have. For the treatment of pituitary adenomas, conventional radiation therapy typically consists of 40-50 Gy administered in 20-25 fractions Pituitary Tumors over 4-6 weeks [192]. One of the major post-radiation The majority of pituitary tumors are adenomas arising from the complications is hypopituitarism, which is both dose and time anterior pituitary gland (adenohypophysis). In addition, injury to the optic nerves and chiasm, lethargy, carcinomas have been described [182]. Pituitary tumors arising from memory disturbances, cranial nerve palsies, and tumor necrosis with the posterior pituitary gland (neurohypophyseal) are also rare [183]. The efects of radiation Pituitary adenomas are the fourth most common intracranial tumor therapy on somatotrophic adenomas is cumulative with time and may afer gliomas, meningiomas and schwannomas [184]. Most patients present with a classic clinical triad of hearing Furthermore, in one case series, only 27% of patients with prolactin loss, tinnitus (high pitched), and disequilibrium [212]. Histologically secreting tumors and 20% of patients with growth hormone-secreting these tumors contain Antoni A and B fbers [213]. Antoni A fbers are macroadenomas returned to baseline hormone levels afer surgical narrow elongated bipolar cells that are tightly packed, while Antoni B resection [198]. Verocay However, the inclusion of post-operative radiation therapy as well as bodies (cellular areas surrounded by parallel arrangement of spindle degree of surgical resection of the tumor infuenced the rate of shaped Schwann cells) are also seen histologically [214]. On the other hand, there were no recurrences three approaches to treating vestibular schwannomas. Tese include observed in patients with a gross total tumor removal who received complete surgical resection, radiation therapy, or monitoring using postoperative radiation therapy [198]. With complete surgical removal, the incidence of recurrence is minimal from 0%-3% [215]. Tere are currently three The posterior pituitary can sometimes be damaged during surgery surgical approaches used including retrosigmoid, which may preserve leading to a condition called central diabetes insipidus, which is hearing, translabyrinthine, which sacrifces hearing but increases characterized by excessive thirst and dilute urine. The tumor Primary Central Nervous System Lymphoma progression rate following subtotal resection is roughly 20% [215]. Recent advances in treatment options have resulted in the use of high-dose chemotherapy in. Whole-brain radiation therapy is ofen used with 40-50Gy, especially when chemotherapy is. Given the considerable advancement of diagnostic imaging, preventive screening, and increasing life spans in. Unilateral vestibular schwannoma at age <30 years or developed countries, these national statistics likely underestimate the. This is partly due to the inherent capacity of malignant tumor cells to invade and cross basement. Unilateral vestibular schwannoma at age <30 and any of the membranes and migrate to healthy tissue. While patients typically following: meningioma, schwannoma, glioma, posterior subcapsular present with non-specifc symptoms, the most frequently observed lens opacity or fndings include weakness, impaired balance, headaches, and seizures. They are typically found in patients with approximately 6%-11% and 3%-8%, respectively (Table 3). For instance malignant associated with a single peripheral nerve and do not acquire malignant melanoma, which represents only 6% of all cancers [229], has the features. However, plexiform neurofbromas are associated with highest propensity of all systemic malignant tumors to metastasize to multiple nerve bundles and although low, have the ability to transform the brain [231]. This is supported by incidence rates of brain into malignant tumors, making these tumors more difcult to treat. Schwannomas are typically well Kidney 2%-6% circumscribed and consist of Antoni A and B fbers. On the other hand, neurofbromas are typically less cellular, not as well Melanoma 6%-11% circumscribed, and consist of wavy collagen fbers with occasional Colorectal 3%-8% neuritis [223]. S-100 staining is ofentimes used to help distinguish these tumors since schwannomas typically display a greater percentage Ovarian 1. However, with both tumors expressing some degree of S-100, this stain alone is not Unknown 2%-14% sufcient diferentiating these tumors. The standard of care for treating these lesions is sources of brain metastases in adults are cancers arising from the lung, usually surgery and/or radiosurgery. In children, the most common source metastatic brain tumors, there are no good chemotherapeutic options. Appropriate surgical rhabdomyosarcoma especially among children younger than 15 years candidates should be free of systemic cancer progression, have [238]. Finally, germ cell tumors are the most frequent source of brain controlled primary disease, and independent function as evident by a metastases in patients 15 to 21 years old [238]. As such, best practices for surgical resection are tumors develop in locations that make it easier to spread to the brain, being evaluated. Anderson, en bloc resection was compared to piecemeal resection in patients with supratentorial and infratentorial single metastases. Namely, leptomeningeal dissemination in patients who underwent piecemeal T1 and T2 weighted imaging modalities with and without contrast tumor resection compared with en bloc resection [251] and a higher are used as the gold standard for initial evaluation.

However gastritis treatment purchase doxazosin 4mg with mastercard, without effective treatment, many people may develop chronic problems over many years. The severity of the initial traumatic response is a reasonable indicator of the need for early intervention. Families and care-givers have a central role in supporting people with stress symptoms. Depending on the nature of the trauma and its consequences, many families may also need support for themselves. Persons exposed to trauma should be assessed for the type, frequency, nature, and severity of the trauma. Assessment should include a broad range of potential trauma exposures in addition to the index trauma. Trauma Exposure Assessment Instruments may assist in evaluating the nature and severity of the exposure. Trauma-related risks include the nature, severity, and duration of the trauma exposure. However, the following screening tools have been validated and should be considered for use. There is insufficient evidence to recommend special screening for members of any cultural or racial group or gender. Screening strategies should, however, balance efficacy with practical concerns. Brevity, simplicity, and ease of implementation should encourage compliance with recommended screening. Care should be exercised in implementing screening in ways that avoid social stigmatization and adverse occupational effects of positive screens. Thirteen instruments were identified as meeting these criteria, all consisting of symptoms of traumatic stress. The review concluded that the performance of some currently available instruments is near their maximal potential effectiveness and that instruments with fewer items, simpler response scales, and simpler scoring methods perform as well as, if not better, than longer and more complex measures. The screen includes an introductory sentence to cue respondents to traumatic events. The operating characteristics of the screen suggest that the overall efficiency. This finding, in combination with the general paucity of empirical data and certain methodological limitations, significantly moderates the conclusions that should be reached from this body of literature. Two studies found Black/African-American veterans to be more severely affected than Hispanics or Whites/Caucasians (Frueh et al. Experiencing anxiety and fear, especially when exposed to events or situations reminiscent of the trauma. Experiencing memory problems, including difficulty in remembering aspects of the trauma. Not being able to face certain aspects of the trauma and avoiding activities, places, or even people that remind you of the event. Useful symptom-related information may include details, such as time of onset, frequency, course, severity, level of distress, and degree of functional impairment. Onset of at least some signs and symptoms may be simultaneous with the trauma itself or within minutes of the traumatic event and may follow the trauma after an interval of hours or days. Symptoms include a varying mixture of the following: A broad group of physical, mental, and emotional signs and symptoms that result from heavy mental and emotional work during exposure to difficult potentially traumatic conditions. The traumatic events that can lead to an acute stress reaction are of similar severity to those involved in post-traumatic stress disorder. It may result from specific traumatic experiences in combat or exhaustion due to the cumulative effects of one or more factors, including sleep deprivation, extreme physical stress, poor sanitary conditions, limited caloric intake, dehydration, or extremes of environmental conditions. Either while experiencing or after experiencing the distressing event, the individual has at least three of the following dissociative symptoms: o A subjective sense of numbing, detachment, and/or absence of emotional responsiveness o A reduction in awareness of his/her surroundings. His/Her personality, body, external events, and the whole world may no longer appear to be real) o Dissociative amnesia. Symptoms may include: the traumatic event is persistently re-experienced in one (or more) of the following ways: Recurrent and intrusive recollections of the event, including images, thoughts, or perceptions. Acting or feeling as if the traumatic event were recurring (includes a sense of reliving the experience, illusions, hallucinations, and dissociative flashback episodes, including those that occur on awakening or when intoxicated). Intense psychological distress on exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event. Physiological reactivity on exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event. Persistent avoidance of stimuli associated with the trauma and numbing of general responsiveness (not present before the trauma), as indicated by three or more of the following: Efforts to avoid activities, places, or people that arouse recollections of the trauma. Persistent symptoms of increased arousal (not present before the trauma), as indicated by at least two of the following: It should emphasize that the observed reactions in the symptomatic survivors are common in the aftermath of trauma and do not signify personal inadequacy, health problems, mental illness, or other enduring negative consequences. Contemporary approaches to early intervention following trauma exposure emphasize the importance of ?normalization of acute stress reactions. Survivors or responders who show distressing symptoms or disturbed behavior should be educated to understand that their reactions are common, normal responses to the extreme events. Such an approach follows from the common clinical observation that individuals experiencing acute stress reactions often interpret their reactions as signs of ?personal weakness or evidence that they are ?going crazy, which increases their demoralization and distress. Normalization is undermined if survivors or responders who are not experiencing disruptive distress show a derogatory or punitive attitude to others who are. The education and normalization may therefore help them recognize how to protect themselves better and to seek care early if symptoms do interfere with their ?self-control. Pre and post-trauma education should include helping the asymptomatic trauma survivor or responder understand that the acute stress reactions of other people are common and probably transient and do not indicate personal failure or weakness, mental illness, or health problems. Education should also include positive messages by identifying and encouraging positive ways of coping, describing simple strategies to resolve or cope with developing symptoms and problems, and setting expectations for mastery and/or recovery. Routine debriefing or formal psychotherapy is not beneficial for asymptomatic individuals and may be harmful. The clinician should educate them about their role in supporting their loved ones and emphasize that normalization is a concept that can incorporate helping asymptomatic survivors to: Recognize that sometimes peoples inadequate attempts to cope with their reactions are also within the range of ?normal for the strange situation. See that it is natural for them to wonder how they are doing and to be surprised or upset by the intensity, duration, or uncontrollability of their reactions. Also unstudied is whether reassurance of normality and likely recovery, provided by co-survivor peers or helpers, actually serves to promote normalization. Recent literature in the area of trauma has highlighted the potential for interventions to exacerbate trauma reactions. Asymptomatic survivors should not be offered services that extend beyond delivery of Psychological First Aid and education. Psychotherapy intervention may actually cause harm in persons not experiencing symptoms of acute stress (Roberts, Kitchiner et al. The general rule of ?do no harm should apply not only to professionals but volunteers alike. Screening and needs assessments for individuals, groups, and populations are important for the provision of informed early intervention following a major incident or traumatic event. When available, the evidence and supporting research are presented in evidence tables. The approach to triage in the immediate response to traumatic exposure for service members with symptoms during Ongoing Military Operations may vary from the management of civilians exposed to traumatic events. Traumatic events are events that cause a person to fear that he/she may die or be seriously injured or harmed. These events also can be traumatic when the person witnesses them happening to others. Such events often create feelings of intense fear, helplessness, or horror for those who experience them. Onset of at least some signs and symptoms may be simultaneous with the trauma itself or may follow the trauma after an interval of hours or days. Symptoms may include depression, fatigue, anxiety, decreased concentration/memory, irritability, agitation, and exaggerated startle response. There are a number of possible reactions to a traumatic situation, which are considered within the "norm" for persons experiencing traumatic stress. These reactions are considered ?normal in the sense of affecting most survivors, being socially acceptable, psychologically effective, and self-limited. In the early stage (the first four days after the trauma exposure), it is important not to classify these reactions as ?symptoms in the sense of being indicative of a mental disorder. Cognitive/mental: amnestic or dissociative symptoms, hypervigilance, paranoia, intrusive re-experiencing d. Providers should confirm that the symptoms are not due to identified medical/surgical conditions requiring other urgent treatment. In the aftermath of any extreme stressful event, most of those suffering from acute traumatic stress reactions will be easy to spot. Among the uninjured there will also be many who look stunned, appear pale and faint, or can be seen to be shaking. Some of those who appear to be suffering from trauma may not even be the actual victims of the disaster but witnesses or rescuers who may be deeply affected by what they are seeing. Some may not be immediately identifiable as traumatized, because they may be highly active looking for others or looking after others and organizing help and rescue. Acute interventions can be envisioned as the mental health correlate of physical first aid, with the goal being to ?stop the psychological bleeding. Once the patient is in a safe situation, the provider should attempt to reassure the patient, encourage a professional healing relationship, encourage a feeling of safety, and identify existing social supports. Establishing safety and assurance may enable people to get back on track, and maintain their pre-trauma stable condition. Address acute medical/behavioral issues to preserve life and avoid further harm by: a. Arrange a safe, private, and comfortable environment for continuation of the evaluation: a. Maintain a supportive, non-blaming, non-judgmental stance throughout the evaluation d. Assist with the removal of any ongoing exposure to stimuli associated with the traumatic event. Evacuate to next level of care if unmanageable, if existing resources are unavailable, or if reaction is outside of the scope of expertise of the care provider. Risk factors for suicide should also be assessed, such as current depression and substance abuse. If significant suicidality is present, it must be addressed before any other treatment is initiated. Some individuals with stress reactions could be at risk for violence toward others. This can be manifested through explosivity and anger problems and may predict risk for violent behavior. For extended discussion of dangerousness to self or others, see Module B: Annotation C Assessment of Dangerousness. Their normal shelter, clothing, and other basic resources may be destroyed or inaccessible. Early interventions should typically seek to address the needs of the individual person, with the aim of promoting normal recovery, resiliency, and personal growth and avoiding additional harm (see Table A-1 Early Interventions. Individual persons who were exposed to trauma as members of a group/unit that existed prior to the trauma event. Some of the acute interventions, such as psychoeducation, may be provided in a group format to maintain unit integrity and promote continuity with established relationships. If indicated, reduce use of alcohol, tobacco, caffeine, and illicit psychoactive substances. Assign job tasks and recreational activities that will restore focus and confidence and reinforce teamwork (limited duty). When the patient is in a safe situation, the clinician should attempt to reassure the patient and encourage a feeling of safety. The fewer traumatic stimuli people see, hear, smell, taste, or feel, the better off they will be. When possible, direct ambulatory survivors: o Away from the site of destruction o Away from severely injured survivors o Away from continuing danger. Connect: Survivors who are encountered will usually have lost connection to the world that was familiar to them. A supportive, compassionate, and nonjudgmental verbal or nonverbal exchange between you and survivors may help to give the experience of connection to the shared societal values of altruism and goodness. Help survivors connect: o To loved ones o To accurate information and appropriate resources o To locations where they will be able to receive additional support o To unit comrades and mission, fostering vertical and horizontal cohesion. However, some may require immediate crisis intervention to help manage intense feelings of panic or grief. It is included as part of the Fundamental Criteria for First Aid knowledge and skills that soldiers should be trained in order to save themselves or other soldiers in casualty situations. Contact and Engagement Respond to contacts initiated by affected persons, or initiate contacts in a non-intrusive, compassionate, and helpful manner 2. Safety and Comfort Enhance immediate and ongoing safety, and provide physical and emotional comfort 3. Stabilization (if needed) Calm and orient emotionally overwhelmed or distraught survivors 4. Practical Assistance Offer practical help to the survivor in addressing immediate needs and concerns 6. Connection with Social Supports Help establish opportunities for brief or ongoing contacts with primary support persons or other sources of support, including family members, friends, and community helping resources 7. Information on Coping Provide information (about stress reactions and coping) to reduce distress and promote adaptive functioning 8. Linkage to Collaborative Services Link survivors with needed services and inform them about available services that may be needed in the future. The amount of time spent on each goal will vary from person to person and with different circumstances, according to need. Stress is inevitable in combat, in hostage and terrorist situations, and in civilian disasters, such as floods, hurricanes, tornadoes, and industrial and aircraft catastrophes. Most emotional reactions to such situations are temporary, and the person can still carry on with encouragement. However, if the stress symptoms are seriously disabling, they may be psychologically contagious and endanger not only the emotionally upset individual but also the entire unit. Even when there is no immediate danger of physical injury, psychological harm may occur. Emotional distress is not always as visible as a wound, a broken leg, or a reaction to pain from physical damage. However, overexcitement, severe fear, excessive worry, deep depression, misdirected aggression, or irritability and anger are signs that stress has reached the point of interfering with effective coping. The discovery of a physical injury or cause for an inability to function does not rule out the possibility of a psychological injury (or vice versa). A physical injury and the circumstances surrounding it may actually cause an emotional injury that is potentially more serious than the physical injury; both injuries need treatment. The person suffering from pain, shock, fear of serious damage to his body, or fear of death does not respond well to joking, indifference, or fearful-tearful attention. Restore confidence with purposeful activities and talk Retain contact with fellow soldiers and unit Remind / Recognize emotion of reaction (specifically potentially life-threatening thoughts and behaviors). Some patients with an acute stress reaction may benefit from augmentation of the acute intervention and additional follow-up. Because people vary in their reaction and in the rate that they recover from traumatic stress, some individuals may require more time or an adjustment of the treatment prior to improvement. Respect individual and cultural preferences in the attempt to meet their needs as much as possible. Biological alterations include disruptions in neurochemicals, sleep patterns, hyperarousal, and somatic symptoms. However, those service members who are deteriorating or who are not responding to acute supportive interventions need to be identified and evacuated to a more definitive level of care. Also, patients who have a high potential for dangerousness or the development of symptoms suggestive of a stress-related disorder. Patients who do not respond to first-line supportive interventions may warrant treatment augmentation or a mental health referral. Although this prevented the pathologizing of transient reactions, it hampered the identification of more severely traumatized individuals who might have benefited from early interventions. The person has been exposed to a traumatic event in which both of the following were present: Either while experiencing or after experiencing the distressing event, the individual has three (or more) of the following dissociative symptoms:

It was jointly organised by the Ministry of Health, Malaysian Society of Anaesthesiologists and National Heart Association in collaboration with the American Heart Association. Since then, a number of changes have been made to both courses to cater to local needs. The Basic Cardiac Life Support Course was renamed Basic Life Support Course and shortened to one day. Similarly the Advanced Cardiac Life Support Course was renamed Advanced Life Support Course and reduced to two days. However, material for the Advanced Cardiac Life Support Course was taken totally from the American Heart Association. With the formation of the Advanced Life Support Subcommittee under the umbrella of National Committee on Resuscitation Training, the Advanced Life Support Training Manual was compiled. I hope the participants of the Advanced Cardiac Support Course will fnd the manual useful and comprehensive. The course emphasizes on enhancing your skills in the treatment of arrest patients through active participation in a series of simulated cardiopulmonary cases.

Thrombosis (pulmonary or coronary), Toxins Advanced Life Support Training Manual 15 Team Dynamics chapter 3 Roles Team Leader Organizes the group, monitors individual performance of team members, backs up team members, models excellent team behavior, trains and coaches, facilitates understanding and focuses on comprehensive patient care. They are clear about their role assignment, prepared to fulfll the role responsibilities, well practiced in resuscitation skills, knowledgeable about the algorithms and committed to success. Team Dynamics and Communication Closed Loop Communication When communicating with team members, the leader should use closed loop communication. The leader gives an order or assignment and then confrms that the message was heard. The team member confrms that the order or assignment was heard and informs the leader when the task is complete. Clear Messages All messages and orders should be delivered in a calm and direct manner without yelling or shouting. The team leader should speak clearly while the team members should question an order if they are unsure what was said. Clear Roles and Responsibilities Every member of the team should know his/her role and responsibilities. A new skill should not be attempted during the arrest, instead call for expert help at an early stage. The team leader can ask for suggestions when the resuscitation efforts seem to be ineffective. Constructive Intervention During a code, a team leader or member may need to intervene if an action is about to occur at an inappropriate time. The person recording the event may suggest that adrenaline be given as the next drug because it has been 5 minutes since the last dose. Reevaluation and Summarizing An essential role of the team leader is monitoring and reevaluation of the status of the patient, interventions that have been done and assessment fndings. Mutual Respect the best teams are composed of members who share a mutual respect for each other and work together in a collegial, supportive manner. Airway obstruction by the tongue or any other foreign body must be excluded before the purpose of ventilation can be achieved. It is also important to note that both systemic and pulmonary circulation are reduced markedly during cardiac arrest so that the normal ventilation perfusion relationships can be maintained with minute ventilation which is much lower than normal. Empirical use of 100% oxygen during resuscitation from cardiac arrest is reasonable. Oxygen Delivering Devices Oxygen administration is always appropriate for patient in acute distress. Table 3: Delivery of Supplementary Oxygen Device Flow Rates Delivered Oxygen (%) -approximate 1L/minute 24 2L/minute 28 3L/minute 32 Nasal cannula 4L/minute 36 5L/minute 40 6L/minute 44 Simple face mask 6-10L/minute 35-60 Venturi mask 4-12L/minute 24-60 (Device specifc) Mask with O2 Reservoir. Non-rebreathing 10-15L/minute 95-100 18 Advanced Life Support Training Manual Nasal Cannula. Do not use more than 6L/minute O2 as this does not increase oxygenation much, yet dries up nasal passages and is uncomfortable to patient. O2 concentration depends on: O2 supply fow rate Pattern of ventilation Patient inspiratory fow rate Simple Face Mask. O2 concentration depends on: O2 supply fow rate Patient inspiratory fow rate Pattern of ventilation Tight ft of the mask. Based on Bernoullie principle O2 is passed through a narrowed orifce and this creates a high-velocity stream of gas. This high-velocity jet stream generates a shearing force known as viscous drag that pulls room air into the mask through the entrainment ports on the mask. If the reservoir bag is kept infated, the patient will inhale only the gas contained in the bag. Oropharyngeal or nasopharyngeal airways may be used to prevent the tongue from occluding the airway. Supraglottic Airways Supraglottic airways are devices designed to maintain an open airway and facilitate ventilation. Insertion of a supraglottic airway does not require visualization of vocal cord and so it is possible to insert without interrupting chest compression during resuscitation. It keeps the airway patent, permits suctioning of airway secretions, enables delivery of a high concentration of oxygen, provides an alternative route for the administration of some drugs, facilitates delivery of a selected tidal volume, and with the use of a cuff, may protect the airway from aspiration. However, it is now clear that the incidence of complications is unacceptably high when intubation is performed by inexperienced providers. If endotracheal intubation is deem essential, it should be done by the most experienced personnel and chest compression should not be interrupted for more than 10-20s. Advance the blade to the vallecula if the curved blade is used or to just beyond tip of epiglottis if the straight blade is used. Lift upward and forward to bring the larynx and vocal cords into view as indicated by the arrow in the diagram above. View the proximal end of the cuff at the level of the vocal cords and advance it about 1 to 2. A lower rate and just adequate tidal volume ventilation is recommended to avoid hyperventilation and over-infation of the lungs. If arrhythmias occur, Step 5 immediately discontinue suctioning and manually bag patient with O2 Prior to repeating the procedure, patient should be ventilated with Step 6 100% O2 for about 30 seconds. Defbrillators Modern defbrillators are classifed according to 2 types of waveforms: monophasic and biphasic. Minimum 150 cm2, 8 to 12 cm in diameter for both handheld paddle electrodes and self-adhesive pad electrodes although defbrillation success may be higher with electrodes 12 cm in diameter rather than with those 8 cm in diameter. When transthoracic impedance is too high, a low-energy shock will not generate suffcient current to achieve defbrillation Electrode/Paddle Placement. Can be at antero-lateral, antero-posterior, anterior-left infrascapular and anterior-right infrascapular locations on the chest/back. For ease of placement and education, anterolateral is a reasonable default electrode placement. Advanced Life Support Training Manual 39 Points to know: Synchronized cardioversion is preferred for treatment of an organized ventricular rhythm. Not recommended for patients in asystolic cardiac arrest as it is not effective and may delay or interrupt the delivery of chest compressions It is reasonable for healthcare providers to be prepared to initiate pacing in patients who do not respond to atropine (or second-line drugs if these do not delay defnitive management). If the patient does not respond to drugs or transcutaneous pacing, transvenous pacing is probably indicated. If further dose is required, it must be titrated carefully to achieve an appropriate blood pressure Atropine Introduction Dose and Administration. May be considered for narrow-complex fbrillation associated with a dangerously reentry tachycardia while preparing for rapid ventricular response. Atrioventricular conduction is slowed, Adverse Effects and Precautions and a similar effect is seen with accessory pathways. Position the unintubated patient in the recovery position to prevent aspiration 2. Should hypotension persist, dopamine titrated to maintain a systolic blood pressure of 90mmHg is the agent of choice 3. Consider anti-arrhythmics that have been effective during the resuscitation as infusions. Common abnormalities that may require correction after the arrest include electrolyte imbalances, hypoxaemia and acidosis. The record allows us to reconstruct the sequence of events with correlation of interventions and responses during the resuscitation. Such documentation allows the evaluation of appropriateness of care and facilities the prospective collection of data for measuring the outcome and effects of training. Advanced Life Support Training Manual 61 Ethical Issues in Cardiopulmonary Resuscitation chapter 10 Ethical Issues in Cardiopulmonary Resuscitation Cardiopulmonary resuscitation is carried out to preserve life. The decision to initiate or continue resuscitative effort should be guided by knowledge, individual patient or surrogate preferences, local and legal requirements. There are 5 important aspects of ethical principles that govern the decision for resuscitation: 1) Autonomy: Right of patient to accept or refuse therapy. Applied to those who has decision-making capacity unless otherwise as declared by a court of law 2) Benefcence: Beneft provided to patient while balancing risks and benefts 3) Non malefcence: Doing no harm or further harm 4) Justice: Equal distribution of limited health resources and if resuscitation is provided it should be available to all who will beneft from it within the available resources 5) Dignity and Honesty: Patient should be treated with dignity. It is a legal binding document in the United States and can be either verbal or written, based on conversations, written directives, living wills or from a durable power of attorney. It is important to note that the court of law accepts written advanced directives more than recollections of conversations. Principles of futility Medical futility occurs when an intervention is unlikely to beneft the patient. Discontinuation of resuscitative efforts or withholding resuscitation should be considered in such situations. However, if the prognosis is in doubt or uncertain, a trial of treatment should be considered until adequate information is gathered to determine the expected clinical course or the likelihood of survival. Dysautonomia is an umbrella term used to describe various conditions that cause a malfunction of the Autonomic Nervous System. These systems are in balance in a healthy person, and react correctly to outside stimuli, such as temperature, stress, and gravity. When they are out of balance and do not function properly for any number of reasons, autonomic dysfunction or dysautonomia occurs. People living with various forms of dysautonomia have trouble regulating these systems, which can result in symptoms such as lightheadedness, fainting, unstable blood pressure, tachycardia or bradycardia, gastoparesis and more. Dysautonomia can occur as a primary disorder or in association with other conditions, such as 1,3 diabetes, rheumatoid arthritis and Parkinson disease. This is not a fully inclusive list, as there are many different forms of dysautonomia. Neurocardiogenic syncope is very common, and most often seen in adolescents and the elderly. Sometimes it is a mild one time event, but for many people it is a chronic and disabling condition. Despite the high prevalence of autonomic disorders, most patients take years to get diagnosed, and many are misdiagnosed before finding an accurate diagnosis. There are many treatments available to improve quality of life, both with medications and lifestyle changes/adaptations geared towards the type of dysautonomia and unique 1, 2, 3, 4, 5 health situation of the patient. Dysautonomia International encourages you to read the summaries of the more common autonomic disorders under our "Learn More" tab.
