Background: COVID-19 related strokes (CORS) are increasingly being diagnosed across the world. The knowledge about the clinical profile, imaging findings and outcomes are still evolving. Here we describe the characteristics of a cohort of 62 CORS patients from 13 hospitals, from Bangalore city, south India. Objective: To describe the clinical profile, neuroimaging findings, interventions and outcomes in CORS patients Methods: Multicenter retrospective study of all CORS patients from 13 hospitals from south India from 1st June 2020 to 31st August 2020.Demographic, clinical, laboratory and neuroimaging data were collected along with treatment administered and outcomes. SARS-CoV-2 infection was confirmed in all cases by RT- PCR testing. The data obtained from the case records were entered in SPSS 25 for statistical analysis. Results: During the 3-month period we had 62 CORS patients, across 13 centers. 60 (97%) had ischemic strokes while 2 (3%) had hemorrhagic strokes. The mean age of patients was 55.66 ±13.20 years, with 34 (77.4%) males. 26 % (16/62) of patients did not have any conventional risk factors for stroke. Diabetes Mellitus was seen in 54.8%, hypertension was present in 61.3%, coronary artery disease in 8% and atrial fibrillation in 4.8%. Base line NIHSS score was 12.7 ±6.44. Stroke severity was moderate (NIHSS 5-15) in 27 (61.3%) patients, moderate to severe (NIHSS 16-20) in 13 (20.9%) patients and severe (NIHSS 21-42) in 11(17.7%) patients. According to TOAST classification for ischemic strokes, 48.3% was stroke of undetermined etiology, 36.6% had large artery atherosclerosis, 10% had small vessel occlusion and 5% had cardioembolic strokes. 3 (5%) received intravenous thrombolysis with tenecteplase 0.2 mg/Kg and 3 (5%) underwent mechanical thrombectomy two endovascular and one surgical. Duration of hospital stay was 16.16± 6.39 days. 16% (13/62) died in hospital, while 37 (59.7%) had a mRS of 3-5 at discharge. Hypertension, atrial fibrillation and higher baseline NIHSS scores were associated with increased mortality. A comparison to 111 historical controls during the non COVID period showed a higher proportion of strokes of undetermined etiology, higher mortality and higher morbidity in CORS patients. Conclusion:CORS are increasing being recognized in developing countries like India. Stroke of undetermined etiology appears to be the most common TOAST subtype of CORS. CORS were more severe in nature and resulted in higher mortality and morbidity. Hypertension, atrial fibrillation and higher baseline NIHSS scores were associated with increased mortality.

Objective:To analyze the surgical outcome and safety of posterior quadrant disconnection in medically refractory epilepsy arising from the posterior head region from a level IV tertiary care center over a period of three years.Materials and Methods:Seven consecutive patients who underwent posterior quadrant disconnection for refractory epilepsy were analyzed.Results:We analyzed the data of seven (n = 7) consecutive posterior quadrant epilepsy patients who underwent posterior quadrant disconnection with a mean age of 8.5 years over the last three years of which 4 were male and 3 females. All patients underwent extensive pre-surgical evaluation including detailed history, examination, prolonged video EEG recordings, neuropsychological testing, MRI brain, DTI, PET scan (n = 6), fMRI (n = 4), WADA test (n = 1) and invasive recording (n = 1), Of seven patients four had left sided pathology and three had right sided pathology. All patients except one underwent pure disconnection and one underwent partial resection.Conclusion:Posterior quadrant disconnection is effective surgical procedure for medically refractory epilepsy arising from the posterior quadrant in carefully selected patients without morbidity or functional disability across various age groups especially in children. In our series, all seven patient had good seizure outcome and none had functional disabilities.

Objective Essential oils are plant‐derived oils and are widely used as an over‐the‐counter remedy for common ailments. Many essential oils are found to have proconvulsant effects. Here we report a small case series of 3 adults with eseential oil‐related status epilepticus. Methods This was an observational study conducted in a tertiary care hospital in south India from January 2018 to December 2019. We collected the demographic, clinical, and imaging features of all cases of status epilepticus resulting from exposure to essential oils. Cases of status epilepticus secondary to all other causes were excluded. Results There were 3 young adults with essential oil‐related status epilepticus. Two had de novo generalized tonic–clonic status epilepticus, and 1 with posttraumatic occipital lobe epilepsy had focal‐impaired awareness status epilepticus. The first 2 cases presented with histories of ingestion of eucalyptus oil. The third case had focal‐impaired awareness status epilepticus after topical application of various balms containing eucalyptus and camphor. Conclusions Proconvulsant essential oils of eucalyptus and camphor can cause both generalized and focal status epilepticus. Physicians dealing with patients of status epilepticus should enquire about the exposure to proconvulsant essential oils.

Cisplatin (CP), a platinum compound, is one of the most active cytotoxic drugs used for cancer treatment. Nephrotoxicity is severe dose limiting side effect of this drug. Abnormal production of reactive oxygen species (ROSs) leading to oxidative stress has been implicated in kidney toxicity by Cisplatin. Here the study was aimed to evaluate nephroprotective effect of ethanolic extract of Terminalia arjuna bark (EETAB) at the doses (200 & 400 mg/kg, body weight) against Cisplatin (7.5 mg/kg, i.p) induced nephrotoxicity in rats. The evaluation was done by measuring % change in body weight, renal function tests such as Blood Urea Nitrogen (BUN), Serum Creatinine (Cr), Serum Total Protein (TP) and also Kidney SOD (Superoxide dismutase),CAT (Catalase), GSH (Reduced glutathione) and MDA (Malondialdehyde) levels altered by Cisplatin administration. Rats treated with EETAB2 (400mg/kg) significantly (P<0.001) reduced the elevated levels of BUN, Cr, TP, MDA and significantly (P<0.001) increased the levels of SOD, GSH, and CAT by restoring kidney architecture. In conclusion EETAB2 (400mg/kg) attractively showed the protection against Cisplatin nephrotoxicity.
