Mercury Toxicity Following Unauthorized Siddha Medicine Intake - A Mimicker of Acquired Neuromyotonia - Report of 32 Cases.

Context: Mercury is used extensively in the preparation of Siddha medicines, after purification. In this study, we present 32 patients of mercury toxicity following unauthorized Siddha medicine intake who mimicked neuromyotonia clinically. We analyzed the clinical features of these patients, the role of autoimmunity in etiopathology, and compared it with acquired neuromyotonia.

"Hyperfrontality" as seen on FDG PET in unmedicated schizophrenia patients with positive symptoms.

Introduction: Decreased frontal activity has been reported widely in unmedicated schizophrenic patients with predominantly negative symptoms. Not many studies have assessed the frontal lobe status in unmedicated patients with positive symptoms.

Patients And Methods: Fifty-one patients with schizophrenia (all unmedicated, 38 never medicated) and 12 healthy age-matched controls were evaluated with FDG PET CT.

Tenofovir induced Fanconi syndrome: A rare cause of hypokalemic paralysis.

We report a 55-year-old female who presented to the emergency department with acute onset quadriparesis. She was diagnosed to have acquired immunodeficiency syndrome 7 years ago and was on tenofovir based anti-retroviral therapy for past 10 months. As the patient also had hypophosphatemia, glucosuria and proteinuria Fanconi syndrome (FS) was suspected.

Hyperostosis frontalis interna mimicking Mount Fuji sign.

We report an interesting case of 'Hyperostosis frontalis interna' in a 73-yr-old female whose MRI pictures mimics the CT appearance of 'Mount Fuji sign' in tension pneumocephalus a neurological emergency.

Outcomes of endovascular coiling of anterior communicating artery aneurysms in the early post-rupture period: a prospective analysis.

Background: There have been significant advances in the technical aspects of endovascular therapy of cerebral aneurysms. Anterior communicating artery (Acom A) aneurysms were traditionally treated by surgical clipping. Endovascular coiling has the distinct advantage of being minimally invasive and can be performed anytime during the course of subarachnoid hemorrhage (SAH).

Non-Hodgkin's lymphoma of the brainstem with atrial septal mass.

Simultaneous occurrence of cardiac and central nervous system tumors have been rarely reported. A 23 years male presented to us with right cerebello-pontine (CP) angle symptoms and signs. Cranial imaging showed a mass lesion in the right pons infiltrating into the right and middle cerebellar peduncles.

Hemicraniectomy for large middle cerebral artery territory infarction: outcome in 19 patients.

Background: Large space-occupying middle cerebral artery infarction accounts for 10-15% of all supratentorial infarctions and carries a mortality of 50% to 80%. Hemicraniectomy may be useful when optimal medical management has failed.

Methods: Between June 1997 and June 2000, 19 patients who fulfilled the clinical and imaging criteria for large middle cerebral artery infarction underwent hemicraniectomy because of impending herniation despite best medical therapy.
