  • Post-dural puncture headache: pathophysiological mechanisms.
    Miguel A Reina

    Dear Editor,

    We thank Dr. Gupta [1] for his interest in our article [2]. His comments [1] are very interesting when we consider how complex the postdural puncture headache (PDPH) physiopathology can be.

    Different and multiple factors contribute in a resulting PDPH, which can justify the differences in the intensity and duration of the headache. Factors such as technique [3-6], doctor’s experience, patien...

  • Birth seasonality and schizophrenia-like psychosis following temporal lobectomy
    Dominik Zumsteg

    Dear Editor,

    We read with great interest the article of Shaw et al [1] reporting on risk factors for the development of a schizophrenia-like psychotic disorder following temporal lobectomy, and would like to offer one additional demographic risk factor not attended by the authors: the seasonality of births.

    In schizophrenia, a consistent 5-8% winter-spring (i.e. December - June) excess of births...

  • Platelets and Migraine: A never-ending story?
    Celio Levyman

    Dear Editor,

    The relationship of migraine and platelets is a very interesting issue. The “platelet theory” of migraine by Deschmuck and Meyer, the “migraine as a platelet disorder” by Hannington and more recent papers discharging the importance of platelet aggregation in this kind of head pain.

    However, the migranous infarct, as described in the HIS Classification and also in the clinical practice, was...

  • Author's response
    Han Soo Chang

    Dear Editor,

    We appreciate Dr. Deogaonkar's interest in our article. We also appreciate his pointing out the feasibility of thecoperitoneal shunting in treating syringomyelia associated with adhesive arachnoiditis (SAA).

    However, our opinion on this subject is somewhat different from his remarks. We have done simulation of thecoperitoneal shunting using our model of SAA; it showed that, if performed wit...

  • Case report does not report sufficient data to support a diagnosis of fatal organophosphorus poisoni
    Michael Eddleston

    Dear Editor,

    We note the report of an unusual organophosphorus (OP) pesticide poisoning published in your journal [1]. However, from the data presented, we are not convinced that the patient’s death can be attributed to OP poisoning. Furthermore, we do not believe that this report can be used to expand the spectrum of syndromes seen following OP poisoning.

    There was no history of ingestion of an OP. In a...

    Ernest H. Friedman

    Dear Editor,

    Hyndman and Ashburn [1] find that those who stopped walking when talking were significantly more disabled (p...

  • Re: Clinical use of paraneoplastic antibodies
    Jeremy H Rees

    Dear Editor

    Dr Grueger raises an interesting and relevant management point about the usefulness or not of testing patients with suspected paraneoplastic neurological disease for the presence of anti-neuronal antibodies.

    I do not agree however that this test has no benefit. These antibodies are highly specific for an underlying tumour e.g. anti-Hu for small cell lung cancer and anti-Yo for breast and gy...

  • Platelet-leukocyte adhesion, migraine, and stroke: a bioclinical perspective
    Vinod K Gupta

    Dear Editor

    Zeller et al showed platelet adhesion to leukocytes during the headache-free interval and a higher baseline of platelet activation in migraine patients without aura; the authors suggest a link between migraine and stroke at the cellular level [1]. Also, they believe that enhanced platelet activation in migraine patients is a marker of the inflammatory process in the trigeminovascular system.

  • Response to Letter to the Editor Wenneberg R.
    W. Brent Tarver

    Dear Editor

    In the Letter to the Editor (Wennberg R. Short term benefit of battery depletion in vagus nerve stimulation for epilepsy. J Neurol Neurosurg Psychiatry 2004;75:939), the author stated that 58% of subjects improved after battery depletion.

    The information provided in the VNS Therapy Physician's Manual states that the information provided was referenced to BASELINE, not to the time just befor...

  • To sleep or not to sleep
    Mark RA Manford

    Dear Editor

    The authors [1]. usefully describe a large series of patients and compare the occurrence of non-epileptic seizures arising whilst apparently asleep.

    This clinical differentiation remains problematic and the rule appears to be emerging that there are no rules. However, to my knowledge there is only one study [2]. (quoted by Duncan et al) with video-EEG-recording, maintaining that patients can...
