Neurocysticercosis is an infection of the central nervous system caused by the larval form of the pork tapeworm Taenia solium. In the brain it occurs in two forms: parenchymal and extraparenchymal or racemose cysts. The clinical presentation of racemose cysts is pleomorphic, and is quite different from parenchymal cysticercosis. The clinical diagnosis of racemose cysts is quite challenging, with neuroimaging being the mainstay. However, the advent of newer brain imaging modalities has made a more accurate diagnosis possible. The primary focus of this article is racemose neurocysticercosis and its multitude manifestations, and includes a discussion of the newer diagnostic modalities and treatment options.
Background:Hashimoto encephalopathy (HE) is a poorly understood and often misdiagnosed entity with variable clinical spectrum. There are many uncertainties that still remain about this condition and the pathological significance of thyroid peroxidase (TPO) antibody.Objective:To characterize the clinical, laboratory and radiologic findings in patients with HE.Design:Retrospective analysis of clinical features and diagnostic test data.Main Outcome Measures:Clinical features, laboratory, radiologic, electroencephalography (EEG) findings associated with HE and therapeutic outcome.Results:Thirteen consecutive patients were identified as having HE. The median age at onset was 48.5 years (range, 19–62 years). There was a female preponderance (76.9%). Clinical manifestations were cognitive impairment and behavioral changes in 10 (76.9%), sleep disturbance in 9 (69.2%), seizures in 6 (46.1%), headache in 4 (30.8%), psychosis or paranoia in 5 (38.5%), transient symptoms in 6 (46.1%), myoclonus in 4 (30.8%), ataxia or gait disorder in 4 (30.8%). The most frequent laboratory abnormalities were increased TPO (n = 13) in all cases, increased thyroid stimulating hormone levels (n = 6), and increased erythrocyte sedimentation rate (n = 5). The cerebrospinal fluid protein level was elevated in 8 of 9 patients (88.8%). Magnetic resonance imaging abnormalities were present in 2 patients (15.4%). EEG changes were seen in 7 patients (53.8%). All but two patients showed significant therapeutic benefit with steroids.Conclusions:HE has a wide range of clinical, laboratory, and radiologic findings. All patients with an unexplained encephalopathy should be screened for this condition as treatment response is excellent. To the best of our knowledge, this is the largest single center clinical series of HE from the Indian subcontinent.
Background
Out of several neuroprotective drugs (NPDs) studied in animals and humans, four NPDs (citicoline, edaravone, cerebrolysin, and minocycline) have been found to have beneficial effects in acute ischemic stroke (AIS).
Objective
The purpose is to evaluate the efficacy of citicoline, edaravone, minocycline, and cerebrolysin compared with placebo in patients with middle cerebral artery (MCA) territory AIS.
Materials and Methods
This was a prospective, single center, single-blinded, and hospital-based study. One hundred patients with MCA territory AIS with 20 patients in each group including control group were included. Barthel index (BI), National Institute of Health Stroke Scale (NIHSS) score, and modified Rankin Scale score were recorded at admission, at day 11 and after 90 days.
Results
The mean NIHSS score was significantly lesser at day 11 and after 90 days in citicoline, edaravone, and cerebrolysin group in comparison with placebo. Similarly, the mean BI score was significantly higher at day 11 and after 90 days in citicoline, edaravone, and cerebrolysin group in comparison with placebo. In minocycline group, there was no significant change in the NIHSS score and BI score at day 11 and after 90 days.
Conclusion
There was significant improvement in the functional outcome of patients with AIS involving MCA territory at 90 days receiving citicoline, edaravone, and cerebrolysin. However, minocycline did not offer the same efficacy as compared with other neuroprotective agents.
Cerebral venous sinus thrombosis (CVST) is common in Asians, accounting for 15% of all strokes in the young. CVST causing malignant cerebral oedema with brain herniation and death are referred as malignant CVST. This study was aimed at evaluating the outcome of patients and factors predicting the outcome with malignant CVST after decompressive surgery. It was a retrospective, observational, single centre, hospital-based and cross-sectional study. Records of patients with malignant CVST who had decompressive surgery were analysed. Over 5 years (2010-2015), 30 patients (15 men and 15 women) underwent decompressive surgery. In univariate analysis, age more than 50 years (p = 0.05); presence of midline shift of more than 10 mm (p = 0.03) and total effacement of basal cisterns (p = 0.01) had significant correlation with poor outcome. On multivariate analysis, presence of midline shift of more than 10 mm (p = 0.01) was a significant predictor of poor outcome. Decompressive surgery is a life saving therapeutic intervention in patients with malignant CVST and more than two-thirds of patient shows favourable outcome. Age more than 50 years, midline shift >10 mm and total effacement of basal cisterns determine poor outcome following decompressive surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
