Drinking habits of 156 consecutive polyneuropathic and 106 consecutive pressure palsy patients were evaluated in retrospect. Respectively, 46 patients (30%) had alcohol polyneuropathy and 32 (30%) got pressure neuropathy while being drunk and these patients were analyzed in more detail. Most of the patients with alcoholic neuropathies were men, those with polyneuropathy being older than those having pressure palsies. Pressure neuropathy coincided with alcoholic polyneuropathy in 13 patients (28%). Other medical complication of heavy alcohol drinking (i.e. liver diseases, seizures and cerebellar signs) were seen in 54% of the patients with polyneuropathy and in 6% of the patients with pressure palsies. Heavy drinking prolonged the disability due to pressure palsy. The present study confirms the significant role of alcohol abuse in etiology of peripheral neuropathies. Heavy drinking seems to worsen the prognosis of these neuropathies.

Four unrelated patients who had the clinical appearance of Miller-Dieker syndrome, also called lissencephaly syndrome, were studied. All four had a typical clinical course with failure to thrive, severe psychomotor retardation, opisthotonos, seizures, and death early in life. None of these children had lissencephaly, the anticipated central feature of this disorder. One of the four had pachygyria, one had polymicrogyria, and two had both pachygyria and polymicrogyria. The brain weights were normal to decreased. The ventricles were dilated in all cases. The cerebral cortex was thickened in each, with decreased white matter and diminution or distortion of the cellular layers, and there were neuroglial heterotopias. The corpus callosum was partially absent in one and thinned in three. The neuropathy found in these children with Miller-Dieker syndrome suggests a spectrum of gyral anomalies resulting from a single type of embryonic error.

Paired serum and cerebrospinal fluid specimens from 19 patients with SLE and central nervous system dysfunction were studied with respect to cerebrospinal fluid IgG index (a measure of intrathecal IgG synthesis), isoelectric focusing using immunoperoxidase staining techniques to detect oligoclonal IgG, and determination of the cerebrospinal fluid/serum albumin quotient (Q albumin) as a measure of blood-brain barrier integrity. Twenty-five patients without neurologic disease and 70 patients with a variety of non-SLE neurologic disorders were also studied for comparison. Of most interest was the observation that 42 percent of the patients with SLE had cerebrospinal fluid oligoclonal IgG, usually in association with elevation of the cerebrospinal fluid IgG index. In addition, two of the cerebrospinal fluid specimens that exhibited oligoclonal IgG also had increased titers of alpha-interferon. Q albumin was normal (under 9.0) in 12 of 13 patients with SLE, who had seizure, psychosis, or cranial neuropathy as principal central nervous system manifestations (mean +/- SD = 5.3 +/- 2.4), but was significantly elevated (mean +/- SD = 27.4 +/- 18.8, p less than 0.001) in five of six patients with diffuse, major central nervous system injury, for example, encephalopathy with coma, transverse myelopathy, paraparesis. Blood-brain barrier impairment was not correlated either with presence of circulating immune complexes or with other clinical or serologic evidence for extra-central nervous system disease activity. Taken together, the data suggest that, within the limitations of the techniques used, impairment of the blood-brain barrier in SLE may be secondary to the central nervous system lesion, rather than a result of systemic immune complex injury. In addition, substantial evidence is provided for an ongoing humoral immune response within the central nervous system in this disorder, which, in certain patients, may be associated with the production of intrathecal alpha-interferon.

We studied offspring of Vietnamese mothers and French fathers who had been born in Vietnam and brought to France to be raised. All but 72 of 3,451 such individuals completed background and neurological questionnaires. Those with positive answers on the latter were examined neurologically. The median year of birth for the 3,379 respondents was 1948, the median year of arrival in France was 1957, and they had resided in France a median of 18 years before interview in 1975. Twenty-five persons had neurological symptoms, and 6 others reported a history of seizures alone. A total of 16 reported seizures: 7 with infantile febrile fits and 9 with afebrile seizure disorders. Three cases of exacerbating-remitting multiple sclerosis (MS) were discovered as well as 3 persons in whom MS was suspected: 1 with cervical myelopathy, 1 with progressive paraparesis, and 1 with bilateral optic neuropathy. The 3 MS cases provided a crude prevalence rate (or 18-year cumulative risk) of 89 per 100,000. Their age-specific prevalence rate was 169 per 100,000 population aged 20 through 29 years. Each measure was similar to such rates for Denmark and had lower 95% confidence limits that clearly exceeded expectations for Vietnam. The results provide further evidence that the risk of MS can be increased by migration in childhood from low- to high-risk regions.

This is the first reported case of dystonia with a partial deletion of the long arm (q) of chromosome 18. Neurologic findings in the 18q- syndrome include mental retardation, seizures, nystagmus, incoordination, tremor, and chorea. A 36-year-old woman with an 18q terminal deletion [karyotype 46,XX,del(18)(q22.2)] had hypothyroidism, diabetes mellitus, borderline intelligence, short stature, short neck, sensorineural hearing loss, and sensorimotor axonal neuropathy. Parents' karyotypes were normal. She had had incoordination and writing difficulty since childhood. Posturing and tremor of the head began at age 16, followed by arm tremors. She had jaw deviation and tremor, neck tremor with retrocollis, involuntary pronation of the right arm, coarse postural and severe action tremor, and tight pen grip with dystonic wrist extension on writing. The 18q- syndrome should be added to the list of genetic causes of secondary dystonia. A karyotype analysis should be considered in secondary dystonias, particularly when there are associated features such as short stature and endocrinopathies.

Patients requiring creation of an arteriovenous (AV) fistula for long-term dialysis access have a high incidence of cardiovascular risk factors, as well as immunosuppression, neuropathy, and platelet dysfunction related to renal failure. However, the morbidity and mortality of AV fistula creation, and the effect of anesthetic technique on outcome, have not been reported. We therefore retrospectively studied all patients (n = 469) having an AV fistula placed at the Mayo Clinic between 1986 and 1991. Preoperative variables studied were age (mean 63 +/- 14 yr), sex (60% male), diabetes mellitus (26% incidence), hypertension (92%), the presence of a previous AV fistula (31%), coronary artery disease (86%), and previous myocardial infarction (MI) (42%). Outcome variables studied were fistula failure prior to first attempted dialysis (8.7% incidence), infection (3.4%), neuropathy (1.9%), seizure (0.2%), nonfatal cardiac event (MI or arrest) (1.5%), and fatal cardiac event (2.1%). Associations of preoperative factors, outcomes, and anesthetic technique were analyzed by analysis of variance and Wilcoxon rank sum analysis for age, and by exact conditional frequency table analysis for all other factors. A previous AV fistula was associated with infection (P < 0.002) and nonfatal cardiac events (P < 0.003). Increased age (P < 0.025) and previous MI (P < 0.01) were associated with adverse cardiac outcomes. Neither local anesthesia, brachial plexus block, nor general anesthesia were significantly associated with an increased frequency of any adverse outcome. The comparison of general with local and brachial plexus anesthetics was limited by low statistical power.(ABSTRACT TRUNCATED AT 250 WORDS)

In a double-blind randomized trial, imipenem/cilastatin (I/C; 500 mg every 6 hours) and ampicillin/sulbactam (A/S; 3 g every 6 hours) were compared in regard to their efficacy for initial empirical and definitive parenteral treatment of limb-threatening pedal infection in diabetic patients. The major endpoints of treatment were cure (resolution of soft-tissue infection), failure (inadequate improvement, necessitating a change in antibiotic therapy), and eradication (clearance of all pathogens from the wound and any bone cultures). Patients in the two treatment groups were similar in regard to the severity of diabetes; presence of neuropathy and peripheral vascular disease; site and severity of infection; pathogen isolated; and frequency of osteomyelitis (associated with 68% of the 48 A/S-treated infections and 56% of the 48 I/C-treated infections). After 5 days of empirical treatment, improvement was noted in 94% of the A/S and 98% of the I/C recipients. At the end of definitive treatment (days' duration [mean +/- SD]: 13 +/- 6.5 [A/S], 14.8 +/- 8.6 [I/C]), outcomes were similar: cure, 81% (A/S) vs. 85% (I/C); failure, 17% (A/S) vs. 13% (I/C); and eradication, 67% (A/S) vs. 75% (I/C). Treatment failures were associated with the presence of antibiotic-resistant pathogens and possible nosocomial acquisition of infections. The number of adverse events among patients in the two treatment groups was similar: 7 in the A/S group (4 had diarrhea and 3 had rash) and 9 in the I/C group (5 had diarrhea, 2 had severe nausea, 1 had rash, and 1 had seizure). Efficacy of A/S and I/C is similar for initial empirical and definitive treatment of limb-threatening pedal infection in patients with diabetes.

A report is given on first experiences with motor cortex stimulation in 10 patients with different forms of neuropathic pain. Three of them had central pain as sequelae of cerebrovascular disease. In none of them did the stimulation provide pain relief. Two patients had pain from peripheral nerve injuries. One did not respond, but the other obtained about 50% pain relief. The remaining 5 patients with trigeminal neuropathy experienced definite pain relief varying between 60 and 90%. During test stimulation most patients had one or two short-lasting generalized seizures. But no one had any motor effects after permanent implantation. Motor cortex stimulation appears to be a new and promising possibility of pain treatment, especially in cases with trigeminal neuropathy, but many problems have yet to be solved, before a clear indication could be given.

A 43-year-old male was referred by a veterinarian who evaluated his dog for a seizure and suspected a toxic lead exposure for both. He refurbished houses, removing old paint, and complained of decreased cognition, fatigue, and muscle cramps. He had a depressed affect, postural tremor, right arm weakness with partial denervation on EMG, and borderline-low sensory nerve action potential (SNAP) amplitudes. A mild anemia and elevated serum and urine lead levels supported a diagnosis of lead neuropathy. Chelation therapy increased urine lead excretion without symptomatic improvement. His brother worked part-time with him and developed similar findings, but also had difficulty chewing, dysphagia, perioral twitching, gynecomastia, and multifocal denervation of extremity and facial muscles. His lead levels were not elevated, but an androgen receptor mutation identified on the X chromosome for both brothers confirmed the diagnosis of X-linked bulbospinomuscular atrophy (Kennedy's disease).

Neurological complications in bone marrow transplant (BMT) patients include central nervous system (CNS) infection, seizure, cerebrovascular accidents, and CNS disease recurrence. The purpose of this study was to describe the pattern and distribution of CNS complications and responses during BMT and to describe the presentation and outcome of select neurological incidents. The records of 200 BMT patients undergoing transplantation in 1989 were randomly selected and comprise the sampling unit for this study. Generally, the peak occurrence of CNS complications was pretransplant through day 21 posttranplant. Neuropathy and somnolence occurred earliest, peaking on day -13 and -8 pretransplant, respectively; confusion or disorientation peaked around day 12 posttransplant. Fifteen patients (7.5%) experienced seizure or suspected seizure, principally of the tonic-clonic type. Fifty-two patients (26%) experienced coma or encephalopathy. Etiologies included respiratory compromise, renal failure, and hepatic dysfunction, often occurring simultaneously. Coma and encephalopathy were commonly associated with terminal events. Because nurses are often the first to identify sensory and perceptual alterations in BMT patients, these results may assist nurses in the early detection of CNS complications.
