RESUMO
We aimed to evaluate the value of immunoadsorption (IA) treatment after the failure of intravenous methylprednisolone (IVMP) therapy for neuromyelitis optica spectrum disorder (NMOSD). Sixty-one NMOSD attacks unresponsive to IVMP were included: 22 patients received rescue IA (IVMP+IA), 24 underwent rescue plasma exchange (PE) (IVMP+PE), and 21 received no further rescue therapy (IVMP alone). The improvement frequencies were higher in the IVMP+IA and IVMP+PE groups than in the IVMP-alone group (P = 0.024). The effective period for IA treatment may be longer than previously thought. IA treatment for IVMP-resistant NMOSD attacks was effective and comparable to PE treatment.

Thymectomy has become an increasingly popular procedure for myasthenia gravis. Knowledge of factors associated with a good outcome (remission) or those most likely to benefit from surgery can help clinical decision-making. A systematic review search was conducted in Medline and Embase for English language studies from 1985 through to February 2014. Studies which evaluated variables associated with, or predictive of, remission in adult (≥18 years) myasthenic patients after thymectomy and using multivariable regression models were included. Statistical pooling was not appropriate due to methodological heterogeneity. From 128 potentially relevant studies, 18 reports of 19 studies met the inclusion criteria. Preoperative mild disease classification (i.e. studies reported this variable as Osserman classification 1, 2A or MGFA I-II) showed the most consistent association with remission. Evidence for several other prognostic factors was inconclusive, or no evidence was found. Gender, age and absence of thymoma (or hyperplasia) were not associated with remission following thymectomy. Patients with mild disease preoperatively may have a better chance of remission of MG after thymectomy.

Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disorder of the central nervous system (CNS), which can be monophasic or with repeated episodes. Relapsing ADEM can be misdiagnosed as multiple sclerosis (MS). We describe here a 16-year-old female patient with multiphasic disseminated encephalomyelitis (MDEM), which was exacerbated after an interferon beta (INF-ß) treatment. The patient presented with polysymptomatic and encephalopathic features at the first attack and was definitively diagnosed with ADEM. During the following 28months, she had two relapses, with the lesions spatially disseminated in time and space, but without encephalopathy. She was diagnosed with MS and started on treatment with IFN-ß injection. A severe relapse occurred 5months after starting IFN-ß treatment, with both the clinical and MRI characteristics worse than during the former 2 relapses, meeting the diagnostic criteria for MDEM. Treatment with IFN-ß was halted, with no new relapses observed over the following 9months. These findings suggest that treating MDEM patients with IFN-ß may exacerbate the disease, similar to that observed during IFN-ß treatment of patients with neuromyelitis optica. Caution should be exercised when treating these patients with IFN-ß.

Intracranial tuberculoma and neurocysticercosis (NCC) are the most frequent granulomatous infections in the central nervous system. Here we report a 41-year-old man with disseminated intracranial tuberculoma mimicking NCC. The patient complained of relapsing vertigo and vomiting consistent with Bruns syndrome. Serum antibodies against cysticercosis were positive. Magnetic resonance imaging (MRI) of the brain showed multiple disseminated ring-enhanced lesions. An initial diagnosis of NCC was made based on clinical signs and MRI. However, during antiparasitic treatment, the patient exhibited fever, meningitis signs, and positive cerebrospinal fluid findings for tuberculosis. The diagnosis was therefore corrected as tuberculoma. After three months of antituberculous treatment, the patient recovered clinically and on MRI. Our results highlight the importance of differential diagnosis of these two diseases in the early stage.
