A 73-year-old woman was admitted to our hospital because of persistent fever, headache and fatigue for several weeks. On admission, she was diagnosed as having meningitis due to Mycobacterium intracellulare (M. intracellulare) detected in her cerebrospinal fluid (CSF) by polymerase chain reaction. Even though anti-tuberculous therapy improved her CSF findings, her condition was not restored. Brain MRI showed multifocal and asymmetrical increases in T2 signals involving white matter and cortical gray-white junction of cerebral hemispheres, cerebellum and brainstem. Based on the progression of clinical symptoms and radiological features, we diagnosed her illness as acute disseminated encephalomyelitis (ADEM) associated with meningitis due to M. intracellulare. Steroid therapy dramatically improved her condition. This is the first report of ADEM following meningitis due to M. intracellulare in a non-immunocompromized host.

Lyme borreliosis is a multisystem disorder caused by Borrelia burgdorferi (Bb). Neurological symptoms such as lymphocytic meningoradiculoneuritis (Bannwart's syndrome), cranial neuritis (II,III,IV,V,VI), encephalitis, transverse myelitis are found in about 10% of cases during the second phase of the disease. In the chronic stage, many months or years after the initial infection, other neurologic complications may occur, such as encephalomyelitis, epileptic crises, cognitive impairment, peripheral neuropathy and psychiatric disturbances such as depression, anxiety, panicc attacks, catatonia, psychosis etc. Some patient continue to experience symptoms of fatigue, insomnia or psychiatric disorder in the post borrelia syndrome. We describe here a patient with a triad of unusual symptoms in chronic LNB including tremor, seizures and psychosis. Standardized medical interview, neurologic examination, neuroimaging, serum and CSF serology as well as EEG and EMNG evaluation were performed. The patient was treated with intravenous ceftriaxone and doxycycline and responded with rapid clinical and functional improvement.Newertheless, he suffered from multiple systemic and neurologic sequelas that influenced his daily activities in post treatment period. Emphasis is placed on the atypical onset and evolution, the difficulties encountered in formulating diagnosis, early treatment and the uncertainties concerning the sequelae after treatment. In patients with non-specific long lasting symptoms in the absence of overt clinical signs suggesting CNS involvement, routine treatment with i.v. ceftriaxone is not to be encouraged.

The aims of this study were to evaluate the attitudes towards H1N1 vaccination and to determine the safety and side effects following 2009 pandemic influenza A (H1N1) vaccination. Pandemic influenza vaccine had been administered to the healthcare personnel in our research and training hospital in December 2009. The rate being vaccinated was established as 40% (800/2000). Four months following vaccination, the opinions about vaccination were asked to the healthcare workers, and also side effects were questioned to the vaccinated group. Two different questionnaires (for vaccinated and unvaccinated subjects) were delivered to the volunteers who agreed to participate in the study. Demographic features, reasons related to being vaccinated or not, were questioned. The vaccinated group was also questioned for the presence of chronic diseases, previous vaccinations (pandemic/seasonal influenza), local or systemic reactions that develop after vaccination. A total of 332 volunteers participated in the questionnaire. Of them 247 (74.4%) were vaccinated and 85 (25.6%) were unvaccinated. Male/female ratio of the participants was 1.2, and 55.7% of them were older than 30-year-old. Most of the participants (82.8%) were highly educated (high school and faculty-graduated). Vaccination rates were found statistically significant in advanced age group compared to young adults (p= 0.042); in male gender compared to females (p= 0.001) and in parents compared to subjects who didn't have children (p= 0.021). Vaccination rates were observed to be higher (57.5%) in non-medical staff (cleaning employers, administrative personnel, etc.) than the physicians (29.1%) and nurses (13.4%), and the rate was also high (54.7%) in personnel who worked in intensive care units, emergency department and administrative units than the personnel who worked in the clinics of internal medicine (22.3%) and surgery (23.1%) (p= 0.001). The most important causes of rejecting vaccination were being afraid of the side effects (69.4%) and not believing the effectiveness of the vaccine (56.4%). The leading causes of accepting vaccination were worries about infecting their family (60.3%) and being in a risk group (54.3%). After vaccination, local reactions (pain, swelling and redness at the vaccination site) were described in 43.3% and systemic reactions (weakness, fatigue, muscle aches, influenza-like symptoms, etc.) were described in 43.7% of the subjects. Severe side effects such as vasculitis, neuritis, encephalomyelitis, Guillian-Barre syndrome and anaphylactic reaction were not observed in any of the vaccinated cases. It was detected that worries about the safety of vaccine had negative impact for vaccination. Since no serious side effects were detected related to vaccination, it was concluded that the vaccine was safe. In spite of the scientific proofs, negative concerns about the safety of the vaccines can unfavorably affect the vaccination campaigns and can jeopardize efforts of influenza control. As a result, data collection systems about the safety and side effects of the vaccine all over the country and regular reports about these data may more efficiently guide vaccination programs in the future.

Fatigue and depression have been shown to be significant problems in children with multiple sclerosis. The rate at which these conditions occur in children with other acquired demyelinating syndromes is unknown. In this cross-sectional study, the authors evaluated 49 children with demyelinating disorders (multiple sclerosis and acute disseminated encephalomyelitis) and 92 healthy controls for depression and/or fatigue using the Behavior Assessment System for Children, Second Edition behavior and mood rating scale and Varni PedsQL Multidimensional Fatigue Scale. The parents of acquired demyelinating syndrome patients were more likely to report elevated depressive symptoms (30.8% vs 10.8%, P = .008). Elevated parent and self-reported total fatigue (25% vs 0%, P < .001, 26.7% vs 8.6%, P = .024) was seen in the patient cohort. The authors conclude that fatigue and depression are far more common in children with acquired demyelinating syndromes than in controls. Clinical attention to and implementation of effective therapies oriented toward these conditions in children with acquired demyelinating syndromes is needed.

A 29-year-old immunocompetent woman was admitted in 2006 with ataxia, limb weakness, generalized dystonia, and vertical diplopia that developed after a febrile episode. Brain magnetic resonance imaging (MRI) revealed the presence of extensive periventricular white matter lesions that did not enhance after gadolinium injection. As low titers of cytomegalovirus-IgM antibodies were found in the serum, a presumed diagnosis of postviral acute disseminated encephalomyelitis (ADEM) was made, and the patient received a 5-day course of 1 g methylprednisolone. The clinical and radiological outcome was very rapidly favorable, and subsequent brain MRIs in 2007 and 2008 were normal. In March 2011, the patient was readmitted with the complaints of abnormal fatigue, imbalance, and speech disorder. The neurological examination showed fluctuating spatiotemporal disorientation with dyscalculia, verbal deafness, gait ataxia, right hemianopia, and pyramidal signs in the four limbs. The brain MRI demonstrated extensive T(2) hyperintense white matter lesions predominating in the left temporal and parieto-occipital lobes, with a pseudotumoral aspect enhancing with gadolinium contrast. A clinical improvement was transiently noted after pulse steroid therapy, but after relapse and radiological worsening, the diagnosis of recurrent ADEM was challenged. The brain biopsy confirmed the presence of primary central nervous system lymphoma (PCNSL) under the variant form of lymphomatosis cerebri. Despite a partial response to chemotherapy, the patient died 8 months after the diagnosis. We discuss the role of sentinel lesions that may precede PCNSL for several years and insist on the importance to consider early brain biopsy in the presence of extensive, non-enhancing white matter lesions, even in a young and immunocompetent patient.

A 62-year-old man with no significant medical history experienced fatigue, night sweats, hoarseness of voice, and dry cough, which were followed by vision disturbances in his left eye. He lost about 4.5 kg (10 lb) in just over a month. Three weeks later, he had difficulty recollecting his e-mail password and trouble with word finding. The next day, he experienced numbness in his left arm. He also developed a maculopapular and erythematous rash in the groin, genitalia, and buttocks. The results of an initial neurological examination were normal, including his higher mental functions. An initial blood workup revealed normocytic normochromic anemia. The results of cerebrospinal fluid studies were unremarkable. Magnetic resonance imaging of his brain at hospital admission revealed multifocal increased T2 signals in the subcortical white matter. A conventional cerebral angiogram was unremarkable. A biopsy specimen from the right frontal lobe revealed demyelination and perivascular lymphocytic infiltration. A provisional diagnosis of acute disseminated encephalomyelitis was made. In spite of steroid treatment and plasmapheresis, his clinical status deteriorated rapidly. The approach to the diagnosis of a rapidly progressive multifocal brain disorder is discussed.

We describe the case of a 3-year-old boy diagnosed with the fulminant form of acute disseminated encephalomyelitis (ADEM). He developed general fatigue, fever, drowsiness and difficulty in walking. He had extensive multiple high-intensity lesions in the white matter of the cerebrum and cerebellum, which are typical findings of ADEM. He became comatose and developed decerebrate rigidity with severe brain edema despite high-dose methylprednisolone therapy, and then was subjected to mild hypothermia therapy, and given i.v. immunoglobulin. The patient recovered remarkably with the sequela of only mild action tremor. The patient was considered to have acute hemorrhagic leukoencephalitis (AHLE), an extremely severe form of ADEM, in terms of the rapidly deteriorating clinical course and neuroimaging features. It was speculated that AHLE and ADEM might be a continuous disease spectrum. It is considered that the severe brain edema associated with ADEM or AHLE is a suitable indication for mild hypothermia therapy.

Multiple sclerosis (MS) is a chronic progressive demyelinating disease of the central nervous system. Common manifestations include paresthesias, diplopia, loss of vision, numbness or weakness of the limbs, bowel or bladder dysfunction, spasticity, ataxia, fatigue, and mental changes. Four main patterns of MS are recognized: relapsing remitting, primary progressive, secondary progressive, and progressive relapsing. The cause of MS is unknown, although it appears to be an autoimmune disease. Much of what is known about MS has been learned from an animal model of the disease, experimental allergic encephalomyelitis.

Experimental autoimmune encephalomyelitis (EAE) is an animal model that mimics many of the clinical and pathological features of the human disease multiple sclerosis (MS). Both are inflammatory demyelinating and neurodegenerative pathologies of the central nervous system associated with motor, sensory, and cognitive deficits. In MS, gray matter atrophy is related to the emergence of cognitive deficits and contributes to clinical progression. In particular, prefrontal cortex injury and dysfunction have been correlated to the development of fatigue, one of the most common and disabling symptoms in MS. However, the molecular bases of these changes remain unknown. Taking advantage of EAE similitude, we herein analyze functional and morphological changes in isolated cortical presynaptic terminals (synaptosomes) from an acute rat model. We found impaired glutamate release in the frontal cortex from EAE rats. This defect appeared along with the onset of the disease, reversing when clinical signs were no more evident. Biochemical analysis of EAE synaptosomes revealed alterations in the presynaptic release machinery and in the response to depolarization, which was accompanied by abnormal synapsin I phosphorylation and dispersion. These changes were associated with reduced synaptic vesicle mobility, with no alterations in synaptosomal morphology as evidenced by electron microscopy. The present are the first pieces of evidence unraveling the molecular mechanisms of frontal cortex neuronal dysfunction in EAE and, possibly, MS.

A twelve-year-old African-American female presented with two week history of progressively worsening headache and fatigue, and vision difficulties for the past week. The physical examination was normal. The neurological evaluation was normal, except for cranial nerves (CN) testing, which showed bilateral restriction of adduction (CN III) and up gaze (CN IV) motions, vertical nystagmus, and left side facial paresis of central origin (CN VII). The bilateral exotropia and ophthalmoplegia are characteristics of WEBINO (Wall-Eyed Bilateral Intranuclear Ophthalmoplegia) syndrome, associated to a brain stem structural lesion. The following causes were evaluated and ruled out: tumor, infection, ischemic stroke, non-infectious inflammation. Pediatric Acquired Demyelinating Syndromes were then considered. Neuromyelitis Optica was ruled out in the absence of neuritis and normal spinal cord MRI. The differential diagnosis between Clinically Isolated Syndrome and Acute Demyelinating Encephalomyelitis, causing an isolated brain stem syndrome, is discussed.
