Review Case Reports
Is there need to search for alternatives to indomethacin for hemicrania continua? Case reports and a review.
Hemicrania continua (HC) is a daily continuous unilateral headache of moderate intensity with super imposed exacerbations of more severe pain accompanied by migrainous and cranial autonomic features. Response to indomethacin is an essential feature in the IHS diagnostic criteria. However, indomethacin is associated with a number of side effects. ⋯ Various drugs have been tried as alternatives to indomethacin in the patients intolerant to indomethacin. We report two cases of HC responsive to topiramate and review the available alternatives for the patients of HC. We also discuss the side effects of indomethacin in the various headache disorders and other painful conditions, and suggest the need for trial of other drugs for the patients of HC.

Review Historical Article
The history of multiple sclerosis: the changing frame of the disease over the centuries.
For centuries, it was recognised that there was a condition characterised by episodic and progressive neurological deterioration, classified as 'paraplegia'. Some early cases of 'paraplegia' have been described in sufficient detail to recognise a condition resembling what we now call multiple sclerosis and these cast an interesting light on the approach to therapy before the disease had a name. Multiple sclerosis was differentiated and 'framed' as a separate identifiable entity by von Frerichs, Vulpian, Charcot and others in the mid-nineteenth century. ⋯ At the same time, attitudes of physicians towards management of people with multiple sclerosis changed. In the last fifty years, the major advances have been in basic research to elucidate the mechanisms and processes underlying the disease, the development of imaging techniques (MRI) and the development of immunomodulatory drugs which, for the first time, are altering the outcome of the disease. We have now entered the therapeutic era of multiple sclerosis, with continual major advances bringing hope and benefit to people with multiple sclerosis.

Severe, abrupt onset headache raises concern for aneurysmal subarachnoid hemorrhage (SAH). The current standard work-up is brain CT scan followed by LP if the CT is non-diagnostic in patients with a normal neurological exam. Some have suggested that angiography is also indicated in this common clinical situation. Is evaluation with brain CT and LP for thunderclap headache to rule out SAH sufficient and is angiography needed? ⋯ Although our methods have important limitations, we believe that this analysis will give clinicians better tools to decide whether or not to pursue further work-up with angiography in patients with thunderclap headache and normal neurological exam, CT, and LP.

Multiple sclerosis (MS) is characterised by focal areas that undergo cycles of demyelination and remyelination. Although conventional magnetic resonance imaging is very effective in localising areas of damage, these techniques are not pathology specific. A newer technique, T(2) relaxation, can separate water from brain into three compartments: (1) a long T(2) component (>2 s) arising from CSF, (2) an intermediate T(2) component (~80 ms) attributed to intra- and extra-cellular water and (3) a short T(2) component (~20 ms) assigned to water trapped in between the myelin bilayers (termed myelin water). ⋯ Two lesions showed low MWF in the core suggesting demyelination upon first appearance. At later time points, one lesion showed a decrease in volume of low MWF, reflecting remyelination whereas the volume of low MWF in the other lesion core remained constant. This work provides evidence that MWF and WC can monitor demyelination and remyelination in MS.

The co-occurrence of myasthenia gravis (MG) and Guillain Barré syndrome (GBS) is uncommon with a few reported cases in the literature. There is only one reported case of MG and Miller Fisher variant of GBS. ⋯ She was proved to have co-occurrence of MG and GBS/Miller Fisher overlap syndrome with positive anti-GQ1b antibody. The unusual finding in this patient raises an interesting question on their pathogenesis with the possibility that prior activation of the immune system may predispose the development of autoantibodies against other antigens within the same set of muscles.
