Establishment of low cost epilepsy surgery centers in resource poor setting.

Purpose: To prospectively assess the feasibility of establishing low cost epilepsy surgery programs in resource poor settings.

Method: We started epilepsy surgery centers in Tier 2 and Tier 3 cities in India in private hospitals. This model is based on the identifying and operating ideal epilepsy surgery candidates on the basis of clinical history, interictal and ictal video-EEG data, and 1.

Nested PCR Assay for Eight Pathogens: A Rapid Tool for Diagnosis of Bacterial Meningitis.

Purpose: Bacterial meningitis is a dreadful infectious disease with a high mortality and morbidity if remained undiagnosed. Traditional diagnostic methods for bacterial meningitis pose a challenge in accurate identification of pathogen, making prognosis difficult. The present study is therefore aimed to design and evaluate a specific and sensitive nested 16S rDNA genus-based polymerase chain reaction (PCR) assay using clinical cerebrospinal fluid (CSF) for rapid diagnosis of eight pathogens causing the disease.

Diagnosis of Herpes Simplex Encephalitis by ELISA Using Antipeptide Antibodies Against Type-Common Epitopes of Glycoprotein B of Herpes Simplex Viruses.

Herpes simplex encephalitis (HSE) represents one of the most severe infectious diseases of the central nervous system (CNS). As effective antiviral drugs are available, an early, rapid, and reliable diagnosis has become important. The objective of this article was to develop a sensitive ELISA protocol for herpes simplex viruses (HSV) antigen detection and quantitation by assessing the usefulness of antipeptide antibodies against potential peptides of HSV glycoprotein B (gB).

Electrophysiological study in neuromuscular junction disorders.

This review is on ultrastructure and subcellular physiology at normal and abnormal neuromuscular junctions. The clinical and electrophysiological findings in myasthenia gravis, Lambert-Eaton myasthenic syndrome (LEMS), congenital myasthenic syndromes, and botulinum intoxication are discussed. Single fiber electromyography (SFEMG) helps to explain the basis of testing neuromuscular junction function by repetitive nerve stimulation (RNS).

Limb-shaking transient ischemic attack.

Limb shaking Transient Ischemic Attack is a rare manifestation of carotid-occlusive disease. The symptoms usually present with seizure like activity and often misdiagnosed as focal seizures. Only on careful history the important clinical clues-which may help in differentiating from seizure-are revealed: Lack of Jacksonian march or aura; precipitation by maneuvers that lead to carotid compression.

Recurrent meningitis due to epidermoid.

Aseptic meningitis is characterized by noninfective serous inflammation of the meninges. It can occur in a recurrent fashion when associated with dermoid and epidermoid cysts due to rupture of cyst contents into subarachnoid space resulting in aseptic chemical meningitis. Bacterial meningitis in association with these tumors is commonly related to a coexisting dermal sinus tract and the most common organism is Staphylococcus aureus.

Atonic variant of benign childhood epilepsy with centrotemporal spikes (atonic-BECTS): a distinct electro-clinical syndrome.

Purpose: To describe the clinical and electroencephalographic features, treatment strategies and outcome in a series of children with the atonic variant of benign childhood epilepsy with centrotemporal spikes (atonic-BECTS).

Material And Methods: Out of the 148 patients with BECTS reviewed from January 2005 to June 2010 in our Institute, there were seven (5%) with atonic-BECTS. All underwent video EEG, high-resolution magnetic resonance imaging (MRI), neuropsychological evaluation and language assessment.

A critical appraisal on the utility of long-term video-EEG monitoring in older adults.

Background: World-over, the majority of patients undergoing video-EEG monitoring (VEM) are in their second or third decades. Although elderly represent the fastest growing segment of population with epilepsy, only few of them undergo VEM. We critically evaluated the utility of VEM in the diagnosis and long-term management of older adults with paroxysmal behavioral events.

Post-irradiation "acquired cavernous angiomas" with drug resistant seizures.

Cavernomas are well-known congenital vascular lesions with presumably high epileptogenicity. We report two patients who developed cavernomas; both were in remission from childhood acute lymphoblastic leukemia following standard chemo-radiotherapy. They developed drug-resistant focal epilepsy secondary to cavernomas and were subjected to surgical/medical management.

Hyperreflexic Guillain-Barré syndrome.

Guillain-Barré syndrome (GBS) is an acquired acute autoimmune polyradiculoneuropathy. The 2 features considered essential for the diagnosis of GBS are progressive motor weakness and areflexia. There have been several descriptions of reflex preservation and hyperreflexia in axonal variant of GBS in Chinese, Japanese, and European populations but it is not common in the Indian subcontinent.

An elusive diagnosis: Scedosporium apiospermum infection after near-drowning.

A 51-year-old male was admitted in our institute following an episode of near-drowning. He later developed ventriculitis and cerebral ring-enhancing lesions. He died following a subarachnoid hemorrhage due to rupture of a mycotic aneurysm involving the right fetal posterior cerebral artery.

Evolution and long term outcome in patients presenting with large demyelinating lesions as their first clinical event.

Objectives: To describe the long term evolution and outcome of a homogeneous cohort of patients (n=14) with large demyelinating lesions (LDLs) as the first clinical event from a group of idiopathic inflammatory demyelinating diseases of central nervous system.

Methods: Detailed review of LDLs from December 2002-January 2007 was made. Patients had at least two magnetic resonance imaging (MRI) and minimum follow-up of 2years.

Ischemic hyperintensities on T1-weighted magnetic resonance imaging of patients with stroke: new insights from susceptibility weighted imaging.

Hyperintensities on T1-weighted magnetic resonance imaging (MRI) in the setting of brain ischemia are usually considered hemorrhagic transformations. Such changes can also be seen due to "incomplete infarction" with selective neuronal loss. Arguments regarding the cause of these T1 hyperintensities have shuttled between gemistocytic astrocyte accumulation, tissue calcification and paramagnetic substance deposition.
