cold sensitivity) Later, weakness and wasting develop, more in the legs than in the arms, and more or less in the distribution as the vascular changes In some cases there may be a mononeuropathy multiplex with severe denervation in the territory of the involved nerves (Garcia-Bragado et al) In a few cases, the two neuropathic syndromes have been combined As remarked earlier, detection of cryoglobulin requires special handling of the blood sample The specimen should be carried to the laboratory in a bath of warm water to prevent precipitation of the protein Any of the paraproteinemic states may be associated with amyloid polyneuropathy This subject is accorded a separate section later The pathology of the cryoglobulinemic and macroglobulinemic neuropathies has been incompletely studied and the mechanisms by which these disorders cause neuropathy are uncertain One presumes that some component of the paraprotein acts as an antineural antibody or that deposition of the protein is in some way toxic In our most thoroughly autopsied case, there was widespread distal axonal degeneration of nondescript type without amyloid deposition or in ammatory cells; yet in other reported cases, amyloid has been found in the nerve and the neuropathy has been attributed directly to it Immune deposits of IgM had impregnated the inner layers of the perineurium in the case reported by Ongerboer de Visser and colleagues Dalakas and Engel have made similar observations In yet other instances, the neuropathy of cryoglobulinemia is due to the intravascular deposition of cryoglobulins, causing a more acute vasculitic mononeuritis multiplex as discussed earlier (Chad et al) Treatment In the macroglobulinemic neuropathies, the use of prednisone, the alkylating agent chlorambucil, cyclophosphamide, and repeated plasma exchange has at times led to improvement both in the systemic and neuropathic symptoms, although recovery has been incomplete The optimal treatment of cryoglobulinemic neuropathy has not been settled We have used plasma exchange and added immunosuppression in the vasculitic variety of this disease Primary (Nonfamilial, AL) Amyloid Neuropathy A heredofamilial type of amyloidosis is well known There are in addition more numerous sporadic instances of a peripheral neuropathy caused by amyloid deposition As in the familial variety, the heart, kidneys, and gastrointestinal tract may be involved This acquired type of amyloid diseae has also been called primary systemic amyloidosis to distinguish it from the variety associated with chronic diseases In most cases, the amyloid is derived from a paraproteinemia for which reason it is included in this section, but the proportion of benign and malignant plasma cell sources of the protein varies from one report to another For example, in the large series of Kyle and Bayrd, only 26 percent of patients with primary amyloidosis had a malignant plasma cell dyscrasia This agrees with our own experience, but other series have found rates of myeloma as high as 75 percent In either case, 90 percent of cases of primary amyloidosis are the result of a monoclonal protein in the blood (rarely polyclonal) Macrophage enzymes cleave the larger immunoglobulin molecules as light chains that aggregate to form amyloid deposits in tissue, or the plasma cells may produce light chains directly ( light chain disease ) Lambda light chain predominates in the idiopathic variety of amyloidosis, and kappa light chain is more common in myeloma In a few cases the light chain is found only in the urine (as Bence Jones protein) In primary amyloidosis there is no evidence of preceding or.

coexisting disease (except the association with paraproteinemia or multiple myeloma) Secondary amyloidosis, an infrequent occurrence nowadays, is the result of chronic infection or other chronic disease outside the nervous system and, as a rule is not associated with neuropathy In contrast, familial amyloidosis, a third variety, is almost invariably associated with neuropathy but is associated with a paraprotein in a small proportion of cases and the amount of immunoglobulin is small (see page 1160) Primary amyloidosis is mainly a disease of older men, the median age at the time of diagnosis being 65 years In our clinical material, the majority of the patients have had peripheral neuropathy but this may re ect a referral bias since in other series less than one-third were so affected (Kyle and Dyck) The neuropathic symptoms and signs are similar to those of hereditary amyloid polyneuropathy discussed further on, but the progress of the disease is considerably more rapid The initial symptoms are sensory numbness, paresthesias, and often acral pain and the signs are characteristic of involvement of small-diameter sensory bers (loss of pain and thermal sensation) It is the painful aspect and the autonomic features discussed later that distinguish this disease from the other paraproteinemic neuropathies and indeed, from most other polyneuropathies Weakness follows, initially limited to the feet but becoming more extensive as the disease progresses and eventually spreads to the hands and arms There is only later a loss of mainly large bers that mediate sensations of touch, pressure, and proprioception Twenty- ve percent of patients have carpal tunnel syndrome from in ltration of the exor retinaculum Exceptionally, patterns other than the painful and sensory predominant polyneuropathy have been associated with amyloidosis Preferential involvement of motor nerves, lumbar roots, plexopathy, and amyloidomas involving single nerves (sciatic, facial, trigeminal) have been reported Unusual cases of mononeuritis multiplex have been dif cult to explain, including a reported case by Gorson and Skinner Autonomic involvement can be severe and may become evident early in the course of the illness; several of our patients presented with disturbances of gastrointestinal motility, especially episodic diarrhea and orthostatic symptoms or impotence and bladder disturbances The pupils may show a slow reaction to light, or there may be a reduction in sweating An in ltrative amyloid myopathy also occurs as a rare complication of the disease; it presents as an enlargement and induration of many muscles, particularly those of the tongue (macroglossia), pharynx, and larynx Progression of the illness is relatively rapid, the mean survival being 12 to 24 months An indolent neuropathy that evolves over years is not likely to be due to amyloidosis, though we have seen such a case Death is usually due to the renal, cardiac, or gastrointestinal effects of amyloid deposits, the manifestations of which are already evident in over half of the patients who present with neuropathy A nephrotic syndrome is characteristic Analysis of the serum and urine, searching for an abnormal paraprotein is the most useful screening test Next in value is a microscopic examination of abdominal fat pad, gingival, or rectal biopsy for deposition of amyloid in tissue or blood vessels If a sensory neuropathy or evidence of organ in ltration is evident, biopsy of the sural nerve or of the involved viscera has a high diagnostic yield Muscle tissue gives variable results The liver biopsy is positive in virtually all cases and the kidney shows amyloid in ltration in 85 percent In several of our patients with a clinical syndrome typical of amyloid neuropathy, but in whom amyloid was absent in the sural nerve, the diagnosis was established only after.

Hypertensive encephalopathy is the term applied to a relatively rapidly evolving syndrome of severe hypertension in association with headache, nausea and vomiting, visual disturbances, confusion, and in advanced cases stupor and coma Multiple seizures are frequent and may be more marked on one side of the body than the other These symptoms of diffuse cerebral disturbance may be accompanied by focal or lateralizing neurologic signs, either transitory or lasting, which should always suggest cerebral hemorrhage or infarction, ie, the more common cerebrovascular complications of severe chronic hypertension A clustering of multiple microinfarcts and petechial hemorrhages (the basic neuropathologic changes in hypertensive encephalopathy) in one region may rarely result in a mild hemiparesis, aphasic disorder, or rapid failure of vision By the time the neurologic manifestations appear, the hypertension has usually reached the malignant stage, with diastolic pressures above 125 mmHg, retinal hemorrhages, exudates, papilledema (hypertensive retinopathy grade IV), and evidence of renal and cardiac disease However, instances of encephalopathy at lower pressures are common, especially if the hypertension has been abrupt in onset (see below) The term hypertensive encephalopathy should be reserved for the above syndrome and should not be used to refer to chronic recurrent headaches, dizziness, epileptic seizures, TIAs, or strokes, which often occur in association with high blood pressure Hypertensive encephalopathy may complicate hypertension from any cause (chronic renal disease, renal artery stenosis, acute glomerulonephritis, acute toxemia, pheochromocytoma, Cushing syndrome), cocaine, or administration of drugs such as amino-
