Spinal cord diseases often have devastating consequences, ranging from quadriplegia and paraplegia to severe sensory deficits due to its confinement in a very small area. Many of these diseases are potentially reversible if they are recognized on time, hence Palabras clave (decs) the importance of recognizing the significance of magnetic resonance imaging when Mйdula espinal approaching a multifactorial disease considered as one of the most critical neurological Enfermedades de la emergencies, where prognosis depends on an early and accurate diagnosis. Las enfermedades de la mйdula espinal tienen con frecuencia consecuencias devastadoras: pueden producir cuadriplejнa, paraplejнa y dйficits sensitivos graves debido a que la mйdula espinal estб contenida en un canal de бrea pequeсa. Muchas de estas enfermedades de la mйdula espinal son reversibles si se reconocen con oportunidad, por ello los radiуlogos deben sensibilizarse sobre la importancia de las imбgenes por resonancia magnйtica en el enfoque de una patologнa multifactorial en la cual el pronуstico depende del diagnуstico precoz y preciso, y por ello constituyen una de las urgencias neurolуgicas mбs importantes. The term myelopathy describes pathologic conditions that cause spinal cord, meningeal or perimeningeal space damage or dysfunction. Traumatic injuries, vascular diseases, infections and inflammatory or autoimmune processes may affect the spinal cord (1) due to its confinement in a very small space. Spinal cord injuries usually have devastating consequences such as quadriplegia, paraplegia and severe sensory deficits. However, imaging is of great importance in order to home in on the diagnosis and classify the etiology appropriately (2-3). Many of the processes affecting the spinal cord may be reversible if recognized and treated early. The vast majority of spinal cord diseases may be treated medically, with surgical treatment reserved for compressive disorders, which constitute a neurological emergency (2). This paper reviews the different etiologies, divided into compressive and non-compressive. Definition and clinical picture It is important not to mistake myelopathy for myelitis. Acute transverse myelopathy (includes non-inflammatory etiologies) and transverse myelitis have been used as synonyms in the published literature (5). Findings of spinal tract injuries, a certain degree of sensory dysfunction, or urinary retention, point to a spinal cord injury. There are certain conditions that may mimic myelopathy, such as myopathy or disorders of the neuromuscular junction, but the absence of a sensory deficit rules them out. On the other hand, bilateral frontal mesial lesions may mimic myelopathy but they are associated with abulia or other signs of frontal dysfunction (6). Myelopathies may have a variable course and may manifest as a single event or as a multi-phasic or recurrent disease. The latter is rare and is usually secondary to demyelinating diseases, vascular malformations of the spinal cord, or systemic diseases (4,5). Spinal cord pathologies may be classified as acute, subacute/ intermittent (6) or chronic, depending on the time course, the extent of the involvement, the clinical picture or syndrome, or the etiology (2-4,6,7). Patients with myelopathies but no evident lesions, or who present with multiple lesions of chronic appearance on magnetic resonance imaging, must be questioned about prior subtle symptoms (6). Acute onset that worsens within hours or days points to a spinal cord infarct or hemorrhage. When symptoms are recent, it is of paramount importance to rule out a surgical emergency. If there is evidence of spinal cord compression due to an acute lesion (epidural metastasis or abscess), definitive management is required in order to avoid damage or to adequately manage all other potential diagnoses.

Toxins Shellfish poisoning is caused by a group of toxins produced by planktonic algae (dinoflagellates, in most cases) on which shellfish feed. To date 57 analogs have been identified, although not all are always present, and they vary greatly in overall toxicity. In addition to saxitoxin (the parent compound), monitoring laboratories typically analyze for approximately 12 other analogs that may contribute measurably to toxicity. For Consumers: A Snapshot Algae are plantlike lifeforms that float or move on their own in water. They vary in size from very small (microscopic) to very large (for example, seaweed, such as kelp). Many of the toxins that build up in shellfish ­ seafood such as oysters, clams, and mussels, to name a few ­ are made by a small type of algae called "dinoflagellates," which swim and have characteristics of both plants and animals. When shellfish eat these algae, the poisons can build up in the shellfish and sicken people who eat them. Others, like diarrhetic shellfish poisoning and azaspiracid shellfish poisoning, mostly cause symptoms like nausea, vomiting, diarrhea, and stomach pain. Besides these kinds of symptoms, some shellfish poisonings, like neurotoxic shellfish poisoning, also cause neurologic effects, such as tingling or numbness of lips and throat, dizziness, and muscle aches. In extreme cases, amnesic shellfish poisoning has resulted in severe neurologic disorders, such as loss of shortterm memory, in some people. Isomers of domoic acid have been reported, but are less toxic than domoic acid itself. Diseases Human ingestion of contaminated shellfish results in a wide variety of symptoms, depending on the toxin(s) present, their concentrations in the shellfish, and the amount of contaminated shellfish consumed. Note: the specific seafood with which each toxin generally is associated is included in this "Disease" section, to help readers link symptoms to potential sources. However, all shellfish (filter-feeding mollusks, as well as the carnivorous grazers that feed on these mollusks, such as whelk, snails, and, in some cases, even lobster and octopus) may become toxic in areas where the source algae are present. In most cases, the toxin has no effect on the shellfish itself, and how long each shellfish vector remains toxic depends on the individual species in question. Additionally, there are non-traditional and emerging vectors of these toxins that also are potentially toxic foods. One example is that pufferfish, which typically is associated with tetrodotoxin (see chapter on Tetrodotoxin), may also contain saxitoxin. Paralytic Shellfish Poisoning Mortality: Death has been reported to occur as soon as 3 to 4 hours after the contaminated food has been consumed. Onset: Symptoms can generally occur within 30 minutes of consuming contaminated seafood, although reports have indicated that symptoms can even ensue within a few minutes, if high enough toxin concentrations are present. Medical treatment consists of providing respiratory support, and fluid therapy can be used to facilitate toxin excretion. For patients surviving 24 hours, with or without respiratory support, the prognosis is considered good, with no lasting side effects. In unusual cases, death may occur from cardiovascular collapse, despite respiratory support, because of the weak hypotensive action of the toxin. Diarrhetic Shellfish Poisoning Mortality: this disease generally is not life-threatening. Onset: Onset of the disease, depending on the dose of toxin ingested, may be as little as 30 minutes to 3 hours. Amnesic Shellfish Poisoning Mortality: All fatalities, to date, have involved elderly patients. Onset: the toxicosis is characterized by onset of gastrointestinal symptoms within 24 hours; neurologic symptoms occur within 48 hours. Human clinical signs of domoic acid toxicity are reported as mild gastrointestinal symptoms, from an oral dose of 0.

If no clear benefit is observed in 4­6 weeks, consider adjusting therapy or alternative diagnoses. For treatment purposes, patients who had 2 exacerbations requiring oral systemic corticosteroids in the past 6 months, or 4 wheezing episodes in the past year, and who have risk factors for persistent asthma may be considered the same as patients who have persistent asthma, even in the absence of impairment levels consistent with persistent asthma. For treatment purposes, patients who had 2 exacerbations requiring oral systemic corticosteroids in the past year may be considered the same as patients who have persistent asthma, even in the absence of impairment levels consistent with persistent asthma. Frequency and severity may fluctuate over time for patients in any severity category. Step 3 Step 4 or 5 and consider short course of oral systemic corticosteroids In 2­6 weeks, evaluate level of asthma control that is achieved and adjust therapy accordingly. Consider short course of oral systemic corticosteroids if exacerbation is severe or patient has history of previous severe exacerbations. All other recommendations are based on expert opinion and extrapolation from studies in older children. Key: Alphabetical order is used when more than one treatment option is listed within either preferred or alternative therapy. Clinicians who administer immunotherapy should be prepared and equipped to identify and treat anaphylaxis that may occur. Steps 2­4: Consider subcutaneous allergen immunotherapy for patients who have allergic asthma (see notes). Intensity of treatment depends on severity of symptoms: up to 3 treatments at 20-minute intervals as needed. Step 6 preferred therapy is based on Expert Panel Report 2 (1997) and Evidence B for omalizumab.
