  • It is One and Half syndrome, not Half and Half syndrome
    Farrukh Akram Baig
    I wish to draw your attention to the effect that the title is erroneous. The condition discussed is ONE AND HALF syndrome and not HALF AND HALF syndrome as proposed by the authors. There is no information in the published literature of existence of a condition called Half and Half syndrome. We are currently in process of submitting an interesting case of ONE and HALF SYNDROME and its response to intavenous immunoglobulins at our S...

  • Rituximab for Myasthenic Crisis
    Marcelo D. Schafranski

    It was with great interest that we read the article published in the Journal where rituximab was successfully used to treat myasthenia gravis refractory cases (1). Here, we describe a case where the drug was administered in a difficult-to treat-myasthenic crisis. A 65-year-old woman who suffered from myasthenia gravis since 2006 was admitted to the intensive care unit (ICU) in severe respiratory distress. The patient was...

  • Superoxide dismutase in brain
    Heikki Savolainen

    Dear Editor,

    I have read with the greatest interest the large investigation on the mutated superoxide dismutase (SOD) frequency in the Dutch amyotrophic lateral sclerosis patients (1). The results seem to show that is very rare in the Netherlands, or it may be only an epiphenomenon from the point of view of the disease pathogenesis.

    This conclusion could be reconciled with the circumstance that a large...

    Vestibular paroxysmia has been defined classically by series of rotational to-and-fro vertigo, precipitated or modulated by head position.Then , descriptional basis of the clinical picture may be disclosed if vertigo may be associated to hipoacusis and tinitus or not.

    In the case of pure tinnitus description , the loud / low pitch sound of the tinnitus may be defined as paroxysmal tinnitus. Ethilogical purposes...

  • Comment on "Magnetic resonance spectroscopy evaluation in patients with neuromyelitis optica"
    Denis B. Bichuetti

    Dear Editor,

    We read with interest the article written by de Seze et al(de Seze, Blanc et al. 2010), published on the April 2010 issue of the Journal of Neurology, Neurosurgery and Psychiatry. The authors describe a transversal investigational research comparing magnetic resonance spectroscopy (MRS) of NAWM and NAGM of 24 patients with NMO, 46% of whom had brain abnormalities, and 12 healthy subjects. In this st...

  • Re:Transcranial magnetic stimulation is a useful diagnostic test in psychogenic paralysis
    Ruth Geraldes

    I thank Dr. Civardi and his group, who have demonstrated a large experience with the practical use of Motor Evoked Potentials, for their interest in our article describing a patient with presumed psychogenic left hemiparalysis and abnormal transcranial magnetic stimulation (TMS) (1). Our initial aim in performing TMS to our patient was exactly to prove that MEPs were normal, as suggested by other authors (including Dr. C...

    Metabolic Syndrome and Alzheimer's Disease: Contrasting Epidemiological Evidence and Possible Underlying Mechanisms

    We thank Giannopoulos and colleagues for their interesting Letter. At present, cumulative evidence suggested that metabolic syndrome (MetS), a constellation of interrelated metabolic derangements increasing the risk of cerebrovascular disease (CVD) and diabetes, has been shown to be in...

  • Re:DAT-SPECT. All that glitters is not gold.
    Eduardo Tolosa
    We wish to thank Dr. Morrish for his comments to our review. He argues in his letter that for diagnostic purposes a technique needs to be sensitive to the disease and reproducible and that DAT-SPECT unfortunately falls down on each. Sensitivity is poor, he says, since DAT-SPECT imaging has been found to be normal in about 5 to 15% of individuals with parkinsonism. Such individuals ( SWEDDs ("scans without evidence of dopaminergic...

  • DAT-SPECT. All that glitters is not gold.
    Paul K Morrish

    Kagi and colleagues (1) provide a review but not a critique of a controversial technique. For a technique to have diagnostic utility it needs sensitivity to the disease and reproducibility; DAT-SPECT unfortunately falls down on each. The review describes the test as around 100% sensitive as a diagnostic tool in detecting PD. The authors conclude that the normal scans in 5-15% of patients with de-novo PD are normal becau...
