Patients With Epilepsy

SUMMARY:Twenty-seven patients with epilepsy as the only manifestation of a cerebral AVM were seen at the MNI/MNH from 1973 to 1981. The nine females and eighteen males between the ages of fourteen and fifty-four years (Mean 25.2 years) had epilepsy for an average of 3.5 years prior to the diagnosis of AVM.Seven patients had primarily generalized seizures, ten patients had partial seizures with complex symptoms, fourteen patients had partial seizures with elementary symptoms, and thirteen patients had secondarily generalized seizures. Although there was no history of intracranial hemorrhage, seven patients had negative hemispheric signs (hemiatrophy, hemianopia, dysphasia, hemiparesis), two had impaired mentation, and two were ataxic. The EEG, normal in ten cases, showed non-epileptiform activity in six cases, and focal epileptiform activity in eleven cases. Angiographic and/or histological examination revealed eight small (less than 2 cm in diameter) and nineteen large lesions. Fifteen AVMs involved the frontal lobe, ten the temporal lobe, five the parietal lobe, and one the occipital lobe. Angiography failed to demonstrate three frontal and three temporal AVMs.Plain CT scanning demonstrated a high or low density lesion without a mass effect in sixteen cases, enlargement of the ipsilateral ventricle or Sylvian fissure in seven cases, and diffuse ventricular enlargement in three cases. CT scanning was performed after the intravenous injection of contrast material in nineteen cases and demonstrated vascular enhancement in fifteen cases and an abnormal blood vessel in six cases. Two angiographically occult AVMs demonstrated vascular enhancement with infusion CT scanning, thereby demonstrating the vascular nature of the lesion where angiography had failed to do so.

The Impact

Abstract. In the study, the neural basis of emotional reactivity was investigated. Reactivity was operationalized as the impact of emotional pictures on the self-reported ongoing affective state. It was used to divide the subjects into high- and low-responders groups. Independent sources of brain activity were identified, localized with the DIPFIT method, and clustered across subjects to analyse the visual evoked potentials to affective pictures. Four of the identified clusters revealed effects of reactivity. The earliest two started about 120 ms from the stimulus onset and were located in the occipital lobe and the right temporoparietal junction. Another two with a latency of 200 ms were found in the orbitofrontal and the right dorsolateral cortices. Additionally, differences in pre-stimulus alpha level over the visual cortex were observed between the groups. The attentional modulation of perceptual processes is proposed as an early source of emotional reactivity, which forms an automatic mechanism of affective control. The role of top-down processes in affective appraisal and, finally, the experience of ongoing emotional states is also discussed.

Traumatic Epilepsy

Introduction. The estimated time interval in which an individual can develop Post Traumatic Epilepsy (PTE) after a traumatic brain injury (TBI) is not clear. Objective. To assess the possible influence of the clinical features in the time interval between TBI and PTE develop­ment. Method. We analyzed retrospectively 400 medical records from a tertiary Brazilian hospital. We selected and reevaluated 50 patients and data was confronted with the time between TBI and PTE devel­opment by a Kaplan-Meier survival analysis. A Cox-hazard regression was also conducted to define the characteristics that could be involved in the latent period of the PTE development. Results. Patients devel­oped PTE especially in the first year (56%). We found a tendency of a faster development of PTE in patients older than 24 years (P<0.0001) and in men (P=0.03). Complex partial seizures evolving to generalized seizures were predominant in patients after moderate (37.7%) and severe (48.8%) TBIs, and simple partial seizures evolving to general­ized seizures in mild TBIs (45.5%). Conclusions. Our data suggest that the first year after a TBI is the most critical period for PTE de­velopment and those males older than 24 years could have a faster development of PTE.

Loss Of Strength

Purpose: Life style disorders demand a strict regimen throughout one’s life among which Hypertension and Diabetes Mellitus are common. Hence the treatment aims an effective control along with Life style modification. The negligence towards the prescribed life style regimen would lead to many complications among which stroke are most prominent and the prevalence in India is 29%. Though the patient is under strict Anti hypertensive medications still one day he/she will land up in stroke hampering his rest of precious life. Aim: With this understanding a successful case report is presented to highlight the importance of Avasthiki Chikitsa with life style modification in controlling Hypertension and treating Pakshaghata from the root level. Materials and Methods: A 74 years old female patient, known case of HTN and DM was brought on a stretcher to the Panchakarma OPD of KLEU Ayurveda Hospital and Research Centre with the complain of loss of strength in left upper and lower limb associated with inability to speak since 9 days. Her MRI suggested Left Hemiplegia with B/L cerebellar hemorrhagic infract in occipital lobe. Initially treatment commenced with Shiromarmaghata Chikitsa with Shamanoushadhi along with modern medication which the patient had been advised. Later on when the patient started to improve in her blood parameters allied science medications were tapered and gradually stopped excluding her routine medication. After the clearance of Avarana, Panchakarma therapies were administered sequentially at various stage with a meticulous diet and exercise. Results: After 22 days of treatment Diabetes and Hypertension were under control, patient was able to walk with minimal support and speech also improved. Conclusion: A well planned diet along with Ayurvedic therapies based on the Awastha provides encouraging results in treating HTN, DM and Pakshaghata.

AbstractNocardia brain abscess is a rare clinical entity, accounting for 2% of all brain abscesses, associated with high morbidity and a mortality rate 3 times higher than brain abscesses caused by other bacteria. Proper investigation and treatment, characterized by a long-term antibiotic therapy, play an important role on the outcome of the patient. The authors describe a case of a patient without neurological comorbidities who developed clinical signs of right occipital lobe impairment and seizures, whose investigation demonstrated brain abscess caused by Nocardia spp. The patient was treated surgically followed by antibiotic therapy with a great outcome after 1 year of follow-up.
