A prospective study of the neurological manifestations in all patients with systemic lupus erythematous (SLE) was conducted between February 1985 to January 1989. Excluding herpes zoster infection of peripheral or cranial nerves, post-herpetic neuralgia and migraine, 36 neurological episodes occurred in 33 patients. The presenting symptoms were mental confusion (10), psychosis (five), seizures (six), focal neurological deficit (three), coma (two), headache (five), blurring of vision (three), neuropathy (one) and myelopathy (one). Of these manifestations, only eight episodes were due to primary involvement by SLE: psychosis (two), seizure (two), multiple cerebral infarcts (one), papillitis (one), neuropathy (one) and myelopathy (one). Infection was the most common secondary cause of neurological episodes: all 10 episodes of mental confusion (fungal seven, pyogenic two, tuberculous one, nocardial one); two of six seizures (tuberculous one, pyogenic one); all five headaches (tuberculous meningitis three, cryptococcal meningitis two). The other secondary causes included steroid psychosis (two), hypertensive encephalopathy with seizure (one) and hypertensive retinopathy (one). Three of five cases of focal neurological deficit were due to macrovascular disease rather than to vasculitic infarction. We concluded that cerebral psychosis was a relatively rare presentation in our patients with SLE. In patients who presented with a neurological problem, especially mental confusion, efforts should be made to ascertain the underlying cause, especially if this may be an infection.

A 7.5 year old boy, known to have a seizure disorder, presented with an infarct in the left middle cerebral artery territory, 10 weeks after severe chickenpox. Immunofluorescent antibody titre to the varicella zoster virus in the cerebrospinal fluid was 1:32. Cerebral angiography showed evidence of focal vasculitis. He presented again seven months later with an acute exacerbation of seizures. Magnetic resonance imaging of the brain showed an old posterior extension of the infarct, but a repeated angiography demonstrated an improvement in the vasculitic process. Cerebrospinal fluid antibody titre was again 1:32. Although this may have been an unfortunate coincidence, a possible association between chickenpox and vasculitis, similar to that reported with herpes zoster, and with potentially significant clinical implications, should be considered. As a definite proof can be obtained only by a brain biopsy, however, which is generally not indicated in such cases, only additional clinical reports can lead to delineation of this association as a definite entity.

A review of 15 cases of pancreas transplantation at the Presbyterian University Hospital in Pittsburgh showed that all of the neurologic complications occurred outside of the pancreas transplantation surgery itself. Major CNS complications included hypoxic encephalopathy (20 per cent), cerebral and spinal-cord infarction (7 per cent), and seizures (13 per cent). These appeared to be closely associated with cardiovascular collapse or cardiac arrest that often occurred following septic, hemorrhagic, or additional surgical-anesthetic stresses, removed in time from the transplantation. When patients who died of sudden cardiorespiratory arrest were included, the overall frequency of global cerebral ischemia was 33 per cent. The occurrence of herpes zoster neuritis (13 per cent) was contrasted with the lack of CNS infections. The possible associations of visual hallucinations with cyclosporine therapy (7 per cent), CSF pleocytosis with OKT3 therapy (7 per cent), and compressive neuropathy with operative-anesthetic monitoring (7 per cent) were discussed in relation to previous reports in the literature. Randomized controlled clinical studies were suggested to distinguish more clearly the complications due to pancreas transplantation from those due to the natural history of the underlying diabetes and to distinguish the beneficial and adverse effects of pancreas transplants from those of coexisting renal transplants.

Twenty-five adults who harbored malignant gliomas received 72 courses of intraarterial 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) (100 mg/m2) and 67 courses of systemic vincristine (1.0 mg/m2) and procarbazine (100 mg/m2) as induction therapy (BVP) followed by 106 courses of systemic 1-(2-chloroethyl)-3-(4-methylcyclohexyl)-1-nitrosourea (methyl-CCNU) (130 mg/m2), vincristine, and procarbazine as maintenance therapy (MVP). With a 6-week interval between each treatment, the median and range for the number of courses of BVP were 3 and 1 to 4 and those for MVP were 3 and 0 to 14, respectively. Fifteen patients (60%) responded to both BVP and MVP, and 10 (40%) did not. The overall median survival time was 12.7 months (range, 1.8 to 48.5+ months). Two of 3 patients who had recurrent gliomas responded and survived for 37+ to 45+ months. Seven of 10 who had nonirradiated glioblastomas responded and survived for 9 to 22 months. Four who had nonirradiated anaplastic astrocytomas all responded and survived for 38+ to 48.5+ months. Two who also received radiotherapy (1 glioblastoma and 1 primitive neuroectodermal tumor) benefited and survived for 16.9 and 28.5+ months. All who did not respond favorably died within 8 months. During the infusion of BCNU, complications included transient orbital and head pain, periorbital and scleral erythema in all patients, and a focal seizure in 1 (4%). During the 6-month induction periods, leukopenia and thrombocytopenia occurred in 1 (4%), deep vein thrombosis occurred in 9 (36%), pulmonary emboli occurred in 8 (32%), upper respiratory infections occurred in 6 (24%), pneumonia occurred in 9 (36%), and herpes zoster occurred in 1 (4%).(ABSTRACT TRUNCATED AT 250 WORDS)

The causes of glioma, the most common type of primary malignant brain tumor, are poorly understood. This study compared the personal and first-degree familial medical histories of 462 adults newly diagnosed with glioma in the San Francisco Bay Area between August 1, 1991, and March 31, 1994, with those of 443 controls who were frequency-matched on age, sex, and ethnicity. Cases and controls had equivalent personal histories of cancers other than brain cancer and most nervous system conditions, but they differed significantly regarding histories of epilepsy, seizures, or convulsions 3 or more years prior to diagnosis (odds ratio = 3.3, 95% confidence interval (CI) 1.4-7.9), chickenpox (odds ratio = 0.4, 95% CI 0.3-0.6), and shingles (odds ratio = 0.5, 95% CI 0.3-0.8). Four cases (less than 1%) and no controls had known genetic disorders (three had neurofibromatosis and one had tuberous sclerosis). Cases and controls had similar family histories of cancer and seizures. However, the odds ratio for a validated family history of primary brain tumor was 2.3 (95% CI 1.0-5.8). These results suggest that although family history of any cancer probably is not an important risk factor for adult glioma, a family history of brain tumors may play a role. Variation in exposure to or biologic response to common viral infections might play a greater role in the etiology of adult glioma than family history.

Acute herpes simplex encephalitis (HSE) carries significant morbidity and mortality even after early treatment with antiviral agents (7). As well as causing acute neurological disease, Herpes viruses are associated with relapsing--remitting (Varicella--Zoster, Epstein-Barr) and chronic (Rasmussen encephalitis) disease processes (1). A two-year-old girl developed acute HSE which was followed by a 10-year neurologic illness characterised by asymmetric spastic tetraparesis, pseudobulbar palsy, the opercular syndrome of Foix-Chavany-Marie (4) and seizures. The neurological signs remained static until the child died suddenly 12 years after disease onset. Neuropathologic examination demonstrated active chronic encephalitis. Herpes simplex virus (HSV) DNA was recovered from formalin-fixed paraffin-embedded brain tissue. This case provides additional evidence for the development of chronic neurological disease attributable to persistence of herpes simplex virus type 1.

Thirty two patients with refractory central and neuropathic pain of peripheral origin were treated by chronic stimulation of the motor cortex between May 1993 and January 1997. The mean follow-up was 27. 3 months. The first 24 patients were operated according to the technique described by Tsubokawa. The last 13 cases (8 new patients and 5 reinterventions) were operated by a technique including localization by superficial CT reconstruction of the central region and neuronavigator guidance. The position of the central sulcus was confirmed by the use of intraoperative somatosensory evoked potentials. The somatotopic organisation of the motor cortex was established peroperatively by studying the motor responses at stimulation of the motor cortex through the dura. Ten of the 13 patients with central pain (77%) and nine of the 12 patients with neuropathic facial pain had experienced substantial pain relief (75%). One of the 3 patients with post-paraplegia pain was clearly improved. A satisfactory result was obtained in one patient with pain related to plexus avulsion and in one patient with pain related to intercostal herpes zoster. None of the patients developed epileptic seizures. The position of the stimulating poles effective on pain corresponded to the somatotopic representation of the motor cortex. The neuronavigator localization and guidance technique proved to be most useful identifying the appropriate portion of the motor gyrus. It also allowed the establishment of reliable correlations between electrophysiological-clinical and anatomical data which may be used to improve the clinical results and possibly to extend the indications of this technique.

We present the neurological complications evaluated in a series of 1000 patients who underwent hematopoietic stem cell transplantation (HSCT). Central nervous system (CNS) neurological complications, particularly brain hemorrhages, were the most common, followed by seizures and CNS infections. An unusual neurological complication was Wernicke's encephalopathy. Less frequent neurological complications were metabolic encephalopathy, neuroleptic malignant syndrome, reversible posterior leukoencephalopathy syndrome, brain infarct and movement disorders. The most common neurological complication of the peripheral nervous system was herpes zoster radiculopathy, while peripheral neuropathies, inflammatory myopathy and myotonia were very rarely found.

Neurologic complications are important causes of morbidity and mortality in heart transplant (HT) recipients. New immunomodulating agents have improved survival rates, although some have been associated with a high rate of neurologic complications (infectious and non-infectious). We conducted this study to analyze the frequency of these complications, before and after the use of daclizumab induction therapy. We reviewed all neurologic complications in our HT cohort, comparing infectious with non-infectious complications over 2 periods of time in which different induction therapies were used (316 patients with OKT3 or antithymocyte globulin from 1988 to 2002, and 68 patients with daclizumab from 2003 to 2006). Neurologic complications were found in 75/384 patients (19.5%) with a total of 78 episodes. Non-infectious complications accounted for 68% of the 78 episodes of neurologic complications. A total of 51 patients and 53 episodes were detailed as follows: 25 episodes of stroke (25 of 78 total episodes, 32%; 19 ischemic, 6 hemorrhagic); 7 neuropathies; 6 seizures; 4 episodes of transient ischemic attack (TIA); 3 anoxic encephalopathy; 2 each brachial plexus palsy and metabolic encephalopathy; and 1 each myoclonia, central nervous system (CNS) lymphoma, subdural hematoma, and Cotard syndrome. Mean time to presentation of stroke, TIA, and encephalopathy was 1 day (range, 1-19 d) posttransplant. Mortality rate among non-infectious complications was 12/53 (22.6%). Infectious complications accounted for 32% of the 78 total episodes. We found 25 episodes in 24 patients: 17 herpes zoster (median, 268 d after HT), 3 CNS aspergillosis (median, 90 d after HT), 1 CNS toxoplasmosis and tuberculosis (51 d after HT), 1 pneumococcal meningitis (402 d after HT), and 2 Listeria meningitis (median, 108 d after HT). The 3 patients with CNS aspergillosis died. The mortality rate among patients with infectious neurologic complications was 12% (42.8% if the CNS was involved). When we compared the OKT3-ATG and daclizumab groups, we found that the incidence of non-infectious complications was 15.1% vs. 7.3%, respectively, and the incidence of infectious complications was 7.5% vs. 1.4%, respectively. All but 1 opportunistic infection occurred in the OKT3-ATG time period. In conclusion, a wide variety of neurologic complications affected 19.5% of HT recipients. Non-infectious causes clearly predominated, but infections still accounted for 32% of the episodes. New monoclonal induction therapies have contributed to diminished CNS opportunistic infections in our program.

Piloerection is a rare ictal manifestation usually associated with temporal lobe epilepsy. We present video and electrographic documentation of pilomotor seizures in a 75-year-old man with left temporal lobe epilepsy and remote herpes zoster encephalitis. In general, piloerection is most often localised to the temporal lobe. Unilateral piloerection is usually associated with an ipsilateral ictal onset. Bilateral piloerection has a less certain lateralising value, although earlier reports suggest left hemispheric predominance [Published with videosequences].
