New palaeomagnetic and rock magnetic results on Mesoproterozoic kimberlites from the Eastern Dharwar craton, southern India: towards constraining India's position in Rodinia

New palaeomagnetic and rock magnetic results are reported for 1.1 Ga Mesoproterozoic kimberlites from the distinct fields of Wajrakarur (WKF), Narayanpet (NKF) and Raichur (RKF) occurring within the Eastern Dharwar craton, southern India. In all, 35 oriented block samples were collected from ten kimberlite pipes and our results constitute first of their kind for the kimberlites from NKF and RKF. Palaeomagnetic data reveal that characteristic remanent magnetization (ChRM) directions of the studied kimberlites show a mean declination of 39 and mean inclination of −16 (N = 4, k = 37.6 and α95 = 15.2) and yield a virtual geomagnetic pole at 44.5°N, 195.4°E (dp = 8.0, dm = 15.6). This new pole position is identical to the earlier reported palaeomagnetic pole that lies at 36.8°N, 212.5°E for some Wajrakarur kimberlites and other such global results at 1100 Ma from Umkondo dolerites, Kalahari craton, southern Africa. The newly obtained palaeomagnetic pole also correlates well with the virtual geomagnetic pole (VGP) generated from the 1.1 Ga Majhgawan kimberlite, Mahoba dyke and the Bhander–Rewa sedimentary Group in the Upper Vindhyan sequence within the Bundelkhand craton of Northern India. Our results support a Mesoproterozoic closure age of the upper sedimentary horizons for the ‘Purana’ sedimentary basins and provide evidence for accretion of the northern and southern Indian cratonic blocks prior to 1.1 Ga. Our study also demonstrates that in ∼1.1 Ga palaeomagnetically based Rodinia reconstructions, India occupies a lower palaeolatitudinal position, was much separated from Australia and that East Gondwana very likely did not form an assembly until the terminal Neoproterozoic

A STUDY ON SYMPTOMS, RISK FACTORS AND PRESCRIBING PATTERN OF DRUGS USED IN STROKE PATIENTS

Objective: This hospital based case study was undertaken with aim to identify the symptoms, risk factors and prescribing trends of medication employed in stroke. The objective of this study was to work out the prevalence of stroke symptoms, risk factors, clinical parameters and medicines prescription pattern in stroke occurred patients.Methods: Study was carried out in the Rohini Multi specialty hospital, Warangal, Telangana, India. Patients visiting the neurology clinic were asked to answer a form covering demographic factors, predominant stroke symptoms and their prevalence. To determine the clinical status of the patient; stroke history was obtained from every subject from a trained medical specialist. Most of the patients' data were collected from case sheets and laboratory reports of patients. Among patients visited the clinic, patients were categorized into Ischemic stroke and hemorrhagic stroke patients. Risk factors, associated co-morbidities and the prescription pattern of various drugs used in stroke were also recorded in patients recruited.Results: Out of 150 patients involved in the study, 100 (66.66%) patients presented with symptoms like slurred speech, followed by weakness on right side in 97 (64.66%) patients, headache in 88 (58.66%) patients, change in speech in 87 (58%) patients, weakness on left side in 58 (38.66%) patients and deviation of mouth in 48 (32%) patients. The most common risk factors associated with the stroke was hypertension in 102 (68%) patients, followed by dyslipidemia in 81 (54.2%) patients, diabetes mellitus in 51 (34.6%) patients, heart disease in 49 (32.6%) patients, smoking in 44 (29.3%) patients, diet in 16 (10.6%) and alcohol in 12 (8%) patients. Majority of the stroke patients was prescribed with anti platelets (85%), dyslipidemics (75%), anticoagulants (36%), and Mannitol (98.5%).Conclusion: The present study helped to identify the cases with predominant symptoms of stroke and to estimate various risk factors in such patients. The findings in our study stress the need for early and appropriate management of stroke to prevent further complications of stroke. Combination therapy, lifestyle changes and better management of risk factors said to have a major effect on recovery of stroke with improved quality of life and symptoms.Â

Tuberous sclerosis with rhabdomyoma

Tuberous sclerosis is a neurocutaneous syndrome characterized by abnormalities of both the integument and central nervous system. We present a case of tuberous sclerosis with rhabdomyoma in the heart. This was a 1½-year-old female child with infantile spasms and rhabdomyoma in heart with mother having neurocutaneous markers of tuberous sclerosis. Magnetic resonance imaging brain and electroencephalography findings were consistent with diagnosis
