Uncommon Headaches
Prabhakar S,Khurana D
Annals of Indian Academy of Neurology , 2002,
Abstract: Some headaches are relatively uncommon. They may be either primary of secondary and their recognition is dependent on the characterization of symptoms as well as identification of certain specific situations in which they need to be considered in the differential diagnosis. Primary headache syndromes like the paroxysmal hemicranias, SUNCT (short-lasting unilateral neuralgiform headache with conjunctival injection and tearing), cough headaches and hypnic headaches are uncommonly encountered in routine clinical practice. They have subtle unique features and specific therapies which differentiate them from the commoner primary headaches. Among the secondary causes, headaches may be an uncommon presenting feature of known clinical disorders, lack of awareness of which may result in significant morbidity. These disorders which may present with headache as the main symptom will be the focus of discussion in this review.
Ordinal Indices of small subspaces of $L_p$
S. Dutta,D. Khurana
Mathematics , 2014,
Abstract: We calculate ordinal $L_p$ index defined in "An ordinal L_p index for Banach spaces with an application to complemented subspaces of L_p" authored by J. Bourgain, H. P. Rosenthal and G. Schechtman, for Rosenthal's space $X_p$, $\ell_p$ and $\ell_2$. We show a subspace of $L_p$ $(2 < p < \infty)$ non isomorphic to $\ell_2$ embeds in $\ell_p$ if and only if its ordinal index is minimum possible. We also give a sufficient condition for a $\mathcal{L}_p$ subspace of $\ell_p\oplus\ell_2$ to be isomorphic to $X_p$.
Ordinal indices for complemented subspaces of l_p
S. Dutta,D. Khurana
Mathematics , 2014,
Abstract: We provide complete isomorphic invariance of a class of translation invariant complemented subspaces of L_p constructed by Bourgain, Rosenthal and Schechtman. We compute ordinal L_p-indices for this class. We further show that the isometric index of a tree subspace over a well founded tree is an invariance for the order of the tree. Finally we provide a dichotomy for the subspaces of L_p with small ordinal indices.
Reappearing CT lesions : 4 cases.
Singh G,Bhatia R,Khurana D,Khurana S
Neurology India , 1999,
Abstract: An overwhelming majority of disappearing CT lesions in India have been aetiologically linked to cysticercosis. We report 4 patients with disappearing CT lesions in whom the lesion later reappeared at the same (3 patients) or different site (1 patient). One patient was a Taenia carrier. Serial MRI evaluation in one patient revealed a persisting lesion in the interval period. The contribution of these observations towards the understanding of the aetiology of disappearing CT lesions is discussed.
A case of emotional facial palsy with ipsilateral anterior inferior cerebellar artery territory infarction.
Khurana D,Sreekanth V,Prabhakar S
Neurology India , 2002,
Abstract: Emotional facial palsy (EFP) commonly results from anterolateral thalamic or striatocapsular infarcts. Its occurrence in brainstem lesions is uncommon, with previously reported cases being restricted to superior cerebellar artery infarction (3 cases). We report an unusual case of EFP ipsilateral to an anterior inferior cerebellar artery infarction, which opens new insights into the facial corticobulbar tract pathway.
Improving Photosynthetic Responses during Recovery from Heat Treatments with Brassinosteroid and Calcium Chloride in Indian Bread Wheat Cultivars  [PDF]
Suboot Hairat, Paramjit Khurana
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.611184
Abstract: Climate change is expected to unleash severe and frequent heat waves in future, adversely affecting crop productivity. The aim of this study was to examine the effect of two separate episodes of heat stress, mimicking heat wave conditions on the physiology of four Indian bread wheat cultivars and to study the ameliorating effects of epibrassinolide (BR) and calcium chloride on the recovery of these cultivars. The two thermo-tolerant cultivars C306 and K7903 suffered less inhibition of photosystem II efficiency as compared to the two thermo-susceptible cultivars HD2329 and PBW343. Application of BR and calcium chloride resulted in faster recovery in all the four cultivars. Measurement of the minimum fluorescence (Fo) versus temperature curves revealed a higher inflection temperature of Fo (Ti) for the two tolerant cultivars as compared to the susceptible cultivars, emphasizing greater thermo stability of the photosynthetic apparatus. The two thermo-tolerant cultivars showed higher photochemistry (ΦPSII) relative to the two susceptible cultivars. An increase in the steady state fluorescence was observed in both the susceptible cultivars as compared to the tolerant cultivars. Expression analysis revealed faster recovery of the transcripts involved in photosynthesis in tolerant cultivars as compared to susceptible cultivars. Exogenous application of the ameliorating compounds resulted in faster recovery of transcripts in all the cultivars. The result suggested that under severe stress conditions tolerant cultivars showed faster recovery and a better thermo-stability of its photosynthetic apparatus as compared to susceptible cultivars and application of epibrassinolide and calcium chloride could ameliorate the damaging effect of severe temperature stress to a considerable level in all the four cultivars under study.
Neurologic complications of dropsy : from possibility to reality.
Prabhakar S,Khurana D,Gill K,Choudhary S
Neurology India , 2000,
Abstract: Epidemic dropsy, which results from the accidental ingestion of mustard oil adulterated with argemone oil, has been associated with certain neurologic symptoms. The occurrence of objective neurologic involvement has, however, precluded this illness. We report two cases, who were victims of epidemic dropsy in the recent outbreak in India and showed objective neurologic deficit in the form of brachial neuritis.
Acute onset paraneoplastic cerebellar degeneration in a patient with small cell lung cancer
Bhatia R,Prabhakar S,Lal V,Khurana D
Neurology India , 2003,
Abstract: A patient with small cell lung cancer presented with a rare presentation of an acute onset pancerebellar dysfunction. His clinical condition markedly improved following the surgical removal of the tumor and chemo- and radiotherapy.
Idiopathic CD4 lymphocytopenia presenting as refractory cryptococcal meningitis
Sharma A,Lal V,Modi M,Khurana D
Annals of Indian Academy of Neurology , 2010,
Abstract: Idiopathic CD4 T-lymphocytopenia (ICL) is a syndrome characterized by depletion of CD4 T-cells without evidence of human immunodeficiency virus (HIV) infection. There are a few reported cases of ICL associated with different diseases and clinical conditions, most commonly the opportunistic infections like Tuberculosis, fungal and parasitic diseases which are also seen in HIV-positive patients. We report a case without risk factors or laboratory evidence of HIV infection who presented with refractory cryptococcal meningitis and was found to have ICL.
