In some patients, an effective musical stimulus often induces emotional and autonomic manifestations before the clinical seizure begins. However, in some patients, the triggers have no particular connotations (140), while in others they may (141). Triggers without particular emotional significance can induce the typical autonomic features before the clinical attack (142,143). Establishment of the seizure as a conditioned response has also been suggested (97,140,142,144), but this view is not generally accepted (145). A case with selfinduction possibly motivated by emotional factors has been described (146). Musicogenic attacks may appear only in adulthood, often in the context of a preexisting symptomatic localization-related epilepsy. Studies in epileptic subjects not sensitive to music show that musical stimuli may have widespread effects on neuronal activity in human temporal lobes, extending well beyond the rather restricted primary auditory area (148); that different components of music have different effects, possibly with specialized lateralization and localization; and that the effects of music differ from those of speech (149,150). Right anterior and mesial hyperperfusion during ictal single-photon emission computed tomography has been documented (154,156) and later detailed coregistration functional imaging supported a privileged role for right temporolimbic activation (157). Zifkin and Zatorre (158) note that more complex musical processing tasks activate more cortical and subcortical territory bilaterally, although with right hemisphere predominance. Hyperexcitable cortical areas could be stimulated to different degrees and extents by different musical stimuli in patients sensitive to these triggers. Gloor (159) suggested that responses to limbic stimulation in epileptic subjects depend on widespread neuronal matrices linked through connections which have become strengthened through repeated use of interest in considering the delay from seizure onset to the development of sensitivity to music and the extent of the networks involved in musical perception. The extreme specificity of the stimulus in some patients and the delay from stimulus to seizure onset can be useful in preventing attacks but these seizures usually occur in patients with partial seizures, and appropriate antiepileptic drugs are generally required. Seizures Induced By Eating (Eating Epilepsy) Boudouresques and Gastaut (160) first described eating epilepsy in four patients who experienced seizures after a heavy meal. Gastric distention may have been at least partly responsible for the attacks (161), but many such seizures occurred early in the meal and were unrelated to gastric distention (162,163). The clinical characteristics are usually stereotyped in individual patients but there are few common features among patients. Some patients have seizures at the very sight or smell of food, whereas others have them only in the middle of a meal or shortly afterward. In some patients, the seizures may be associated with the emotional or autonomic components of eating; in others, they are associated with sensory afferents from tongue or pharynx. These seizures have also been documented in young children, in whom they can be mistaken for gastroesophageal reflux (164). In contrast, patients with localized extralimbic, usually postcentral, seizure onset develop reflex activation of seizures later in their course, with less constant triggering by eating and more prominent spontaneous seizures. These patients typically have more obvious lesions and findings on neurologic examination. Several investigators suggest that interaction of limbic and extralimbic cortices (166) and contributions from subcortical structures, such as hypothalamus (160,167,168), are particularly important. Other proposed triggering mechanisms include a conditioned response, mastication (167), stimulation of the esophagus (169), and satisfaction of a basic drive (164). That obvious combinations of several stimuli are required in some cases (170,171) added to the circumstantial evidence favoring an interaction among cortical areas and diencephalic structures, which in other cases could involve less obvious combinations of stimuli. When the abnormal cortex is located in regions responding to proprioceptive and other sensory afferents (especially lingual, buccal, or pharyngeal) activated by the extensive sensory input generated by a complex behavior such as eating, patients may be more sensitive to the physical manipulation of food, texture, temperature, and chewing. A similar mechanism, but with afferents recruiting hyperexcitable temporolimbic structures, may also operate in subjects with temporolimbic seizure onset, who may be more sensitive to gustatory, olfactory, affective, or emotional stimuli or to stimuli arising from more distal parts of the gut. Alerting stimuli have been reported to abolish attacks (172), providing further circumstantial evidence for the participation of an increasing cortical mass and of subcortical influences in some cases of reflex epilepsy. The extraordinarily high frequency of seizures associated with meals in Sri Lanka (173) may be ascribed to the inclusion of all attacks occurring from 0. Seizures Triggered by Somatosensory Stimulation Seizures may be induced by tapping or rubbing individual regions of the body (110). These are partial seizures, often with initial localized sensory symptoms and tonic features, and typically occur in patients with lesions involving postrolandic cortex. A well-defined trigger zone may be found as in patients whose seizures are triggered by brushing the teeth (193). Drugs for partial seizures are needed, but the seizures may be intractable and require evaluation for surgery.

An interictal image is subtracted from the ictal image to derive the difference in cerebral blood flow related to focal seizures (110). The goal of epilepsy surgery is to remove the epileptogenic zone, while preventing functional deficits. Neuropsychological testing is used to provide additional quantification and localizing information of cognitive deficits that hint at the functional deficit zone. Neuropsychological findings can also anticipate possible cognitive decline after epilepsy surgery. This is especially important if the epileptogenic zone or lesion is in close proximity or overlapping with eloquent areas. Besides defining eloquent cortex, it can be used to lateralize and localize the epileptogenic zone by showing regions of functional deficit. The Wada test involves angiography and injection of a short-acting barbiturate into the internal carotid artery in order to temporarily simulate the effects of epilepsy surgery on language and memory. Blood flow increase exceeds the increase in local cerebral oxygen, and this leads to a localized increase in the ratio of oxyhemoglobin to deoxyhemoglobin (27,28). It can localize brain function and functional deficits, and may therefore serve as an estimate of the functional deficit zone. Decreased metabolism is thought to represent the functional deficit zone and may be related to various factors, such as underlying structural lesion, inhibitory mechanisms of seizures, atrophy, neuronal loss, decreased synaptic activity, and postictal depression of metabolism. This method can detect interictal spike-related changes and may be helpful in the localization of interictal epileptiform discharges. Main goal is development of a localization hypothesis on the basis of available information. The ultimate goal of preoperative planning is to provide patients with seizure reduction or freedom, improved quality of life, and minimal deficit. This can be achieved by an understanding and demarcation of the epileptogenic zone, which is unique to each epilepsy patient, and when completely resected renders the patient seizure-free.

Effective epilepsy surgery can lead to a significant reduction of seizures or seizure freedom, leading to better quality of life, less injuries secondary to seizures, and possibly improvements in development and cognition. Successful surgery can only be performed after a detailed evaluation to define the epileptogenic zone pre- and perioperatively. The process begins with a localization hypothesis using clinical history of ictal semiology to delineate the symptomatogenic zone and possibly the functional deficit zone. Once medical intractability is confirmed, this hypothesis is corroborated by other diagnostic modalities.

There are no studies investigating the value of non-pharmacological therapies (eg, physiotherapy, relaxation techniques, diets, etc. For Biqi capsules there is low QoE indicating a higher response rate at week 12 (57). See online supplementary file S2, on the Arthritis & Rheumatology web site at onlinelibrary. None of the panel members disclosed any conflict of interest associated with the development of these recommendations. Remission and relapse have been heterogeneously defined in the literature, as we pointed out previously (65). This necessitated the use of relevant external evidence to strengthen this aspect of our recommendations. These recommendations should support clinicians to achieve the best patient outcomes. Further research on existing drugs is necessary to offer additional, evidence-based treatment options to our patients. We anticipate an update of these recommendations 3 years after their publication; however, an earlier revision may be necessary if new data emerge that would modify the current recommendations. All authors had full access to all of the data (including statistical reports and tables) in the study and can take responsibility for the integrity of the data and the accuracy of the data analysis.

Pts usually present in adulthood with xanthomas and premature coronary and peripheral vascular disease. Comorbidities, such as diabetes mellitus, obesity, or hypothyroidism, should be optimally managed. Therapy begins with a low-fat diet and lifestyle modification, but pharmacologic intervention is often required (Table 189-2). The classic clinical constellation of hemochromatosis is a pt presenting with bronze skin, liver disease, diabetes, arthropathy, cardiac conduction abnormalities, and hypogonadism. Clinical Features Early symptoms include weakness, lassitude, weight loss, a bronze pigmentation or darkening of skin, abdominal pain, and loss of libido. If untreated, liver disease progresses to cirrhosis, and further to hepatocellular carcinoma in ~30% of pts with cirrhosis. Diabetes mellitus is more common in pts with a family history of diabetes, and hypogonadism may be an isolated early manifestation. In an otherwise-healthy person, a fasting serum transferrin saturation >50% is abnormal and suggests homozygosity for hemochromatosis. In most untreated pts with hemochromatosis, the serum ferritin level is also greatly increased. Liver biopsy may be required in affected individuals to evaluate possible cirrhosis and to quantify tissue iron. Death in untreated pts results from cardiac failure (30%), cirrhosis (25%), and hepatocellular carcinoma (30%); the latter may develop despite adequate Fe removal. Chelation therapy is indicated, however, when phlebotomy is inappropriate, such as with anemia or hypoproteinemia. Each of the nine disorders causes a unique pattern of overproduction, accumulation, and excretion of intermediates of heme synthesis. The major manifestations of the hepatic porphyrias are neurologic (neuropathic abdominal pain, neuropathy, and mental disturbances), whereas the erythropoietic porphyrias characteristically cause cutaneous photosensitivity. Laboratory testing is required to confirm or exclude the various types of porphyria. Clinical and biochemical manifestations may be precipitated by barbiturates, anticonvulsants, estrogens, oral contraceptives, the luteal phase of the menstrual cycle, alcohol, or low-calorie diets. Narcotic analgesics may be required during acute attacks for abdominal pain, and phenothiazines are useful for nausea, vomiting, anxiety, and restlessness. It is due to partial deficiency (familial, sporadic, or acquired) of hepatic uroporphyrinogen decarboxylase. The skin manifestations differ from those of other porphyrias, in that vesicular lesions are uncommon. Chronic skin changes may include lichenification, leathery pseudovesicles, labial grooving, and nail changes. Protoporphyrin levels are increased in bone marrow, circulating erythrocytes, plasma, bile, and feces; protoporphyrin in erythrocytes is free rather than zinc-complexed as it is in other types of porphyria or hematologic disorders. Cholestyramine or activated charcoal may promote fecal excretion of protoporphyrin.
