In GBS patients with respiratory compromise, conservative intubation does not increase mortality and disability.

Pseudomeningocele is a well known complication of foramen magnum decompression. Symptomatic subdural hygroma has not previously been described. We discuss a case of Arnold Chiari malformation type 1 in a 55-year-old Caucasian woman who underwent foramen magnum and upper cervical decompression and who developed a symptomatic subdural hygroma 2 weeks following surgery. This complication was most likely due to a technical error during surgery. It responded favourably to conservative therapy.

Patients with neurologic Wilson disease (NWD) may worsen on treatment, but there is no study evaluating the role of oxidative stress. We report the role of plasma glutathione (GSH), total antioxidant capacity (TAC) and malondialdehyde (MDA) in the worsening of NWD following treatment. Fifty-one treatment-naïve NWD patients were subjected to detailed clinical evaluation. The severity of NWD was noted, and dystonia was measured by Burke-Fahn-Marsden (BFM) score. Their hematological, serum chemistry, ultrasound abdomen and cranial MRI changes were noted. Plasma GSH, TAC and MDA, serum free copper (Cu) and 24-h urinary Cu were measured at admission and at 3 and 6 months after treatment. The patients were considered worsened if there was one or more grade deterioration in severity scale, >10 % deterioration in BFM score or appearance of new neurologic signs. The median age of the patients was 11 (5-37) years, and 12 were females. Following treatment, 25 patients improved, 12 worsened, and 14 had stationary course. The worsened group at 3 months had lower GSH (1.99 ± 0.17 vs. 2.30 ± 0.30 mg/dl; P = 0.004) and TAC (1.59 ± 0.12 vs. 1.82 ± 0.17 mmol Trolox equivalent/L; P = 0.001) and higher MDA (5.24 ± 0.22 vs. 4.34 ± 0.46 nmol/ml; P < 0.001) levels compared to the improved group. These changes were associated with increased serum free Cu (41.81 ± 3.31 vs. 35.62 ± 6.40 µg/dl; P = 0.02) and 24-h urinary Cu (206.42 ± 41.61 vs. 121.99 ± 23.72 µg/24 h; P < 0.001) in the worsened compared to the improved group. All the patients having worsening were on penicillamine. Worsening following chelating treatment in NWD may be due to oxidative stress which is induced by increased serum free Cu. These results may have future therapeutic implication and needs further study.

Hepatitis E virus (HEV) is an important cause of repeated waterborne outbreaks of acute hepatitis. Recently, several extrahepatic manifestations (EHMs) have been described in patients with HEV infection. Of these, neurological disorders are the most common EHM associated with HEV. The involvement of both the peripheral nervous system and central nervous system can occur together or in isolation. Patients can present with normal liver function tests, which can often be misleading for physicians. There is a paucity of data on HEV-related neurological manifestations; and these data are mostly described as case reports and case series. In this review, we analyzed data of 163 reported cases of HEV-related neurological disorders. The mechanisms of pathogenesis, clinico-demographic profile, and outcomes of the HEV-related neurological disorders are described in this article. Nerve root and plexus disorder were found to be the most commonly reported disease, followed by meningoencephalitis.
