Tricuspid endocarditis in hyper-IgE syndrome
Gupta S,Mittal A,Gupta S,Jagdish
Journal of Postgraduate Medicine , 2010,
Abstract: Hyper-IgE syndrome is a congenitally acquired primary immune deficiency condition. We report a case of possible hyper-IgE syndrome who presented with multiple cold skin abscesses and chest infection due to Staphylococcus aureus and hyper-IgE findings. Patient also had tricuspid valve acute bacterial endocarditis with purulent pericarditis which is very rare. This case is presented to highlight that early diagnosis and treatment in such cases decreases the mortality and morbidity in phagocytic disorders.
Modified Grover's search algorithm for the cases where the number of solutions is known
A. S. Gupta,M. Gupta,A. Pathak
Physics , 2005,
Abstract: Grover's search algorithm searches a database of $N$ unsorted items in $O(\sqrt{N/M})$ steps where $M$ represents the number of solutions to the search problem. This paper proposes a scheme for searching a database of $N$ unsorted items in $O(logN)$ steps, provided the value of $M$ is known. It is also shown that when $M$ is unknown but if we can estimate an upper bound of possible values of $M$, then an improvement in the time complexity of conventional Grover's algorithm is possible. In that case, the present scheme reduces the time complexity to $O(MlogN)$.

Quantitative anatomy of the lateral masses of the atlas and axis vertebrae.
Gupta S,Goel A
Neurology India , 2000,
Abstract: The study was carried out to determine the safe site of entry and the appropriate trajectory of the screw implantation in the lateral masses of atlas (Cl) and axis (C2) during their fixation using the plate and screw technique. Fifty dried specimens of atlas and axis vertebrae were studied. Various dimensions of the lateral masses were quantitatively measured, laying stress on their relationship with the vertebral artery foramen. As the vertebral artery foramen was present entirely in the transverse process in all specimens, screw implantation in the facet of atlas was relatively safe. Best direction of screw implantation in the facet of atlas was observed to be 15 degrees medial to sagittal plane and 15 degrees superior to axial plane. It should be implanted from the middle of the posterior surface of facet. Vertebral artery foramen formed a deep groove in the undersurface of a majority of superior facets of axis. In 15% facets, vertebral artery foramen occupied the entire undersurface of the superior facet. Safe angle for screw implantation in the facet of axis through its pedicle was seen to be 40 degrees medial to sagittal plane and 20 degrees superior to axial plane. Safe site of screw entry in the axis was superior and medial third of the posterior surface of the pedicle. Quality of cancellous bone in the lateral masses in the proposed trajectory of screw in Cl and C2 was good, providing an excellent purchase of the screw.
Reconstruction of the skull base : a review of personal techniques.
Goel A,Gupta S
Neurology India , 2000,
Abstract: With increasing technological and surgical sophistication in cranial base and craniofacial surgery, reconstructive efforts are challenged to provide a reliable means of compartmentalisation. Some improvised methods of basal reconstruction with vascularised pedicle flap are described in this presentation. The dependable blood supply, long length, ease of harvesting and the ability to alter the arc of rotation of the described flaps make them versatile for lining skull base. The flaps may be used to cover defects, may be folded for bulk and may be used to carry blood supply to poorly vascularised recipient sites. The techniques are presented.
Finite-Size Scaling on the Ising Coexistence Line
S. Gupta,A. Irbaeck
Physics , 1992, DOI: 10.1142/S0129183192000749
Abstract: We report tests of finite-size scaling ansatzes in the low temperature phase of the two-dimensional Ising model. For moments of the magnetisation density, we find good agreement with the new ansatz of Borgs and Koteck\'y, and clear evi consequences of the convexity of the free energy are not adequately treated in either of these approaches.\lb {\it Keywords}\/: Finite-size scaling, 2-d Ising, pure-phase susceptibility.
Finite-Size Scaling on the Ising Coexistence Line
S. Gupta,A. Irbaeck
Physics , 1992, DOI: 10.1016/0920-5632(93)90343-5
Abstract: We study the finite-size scaling of moments of the magnetization in the low-temperature phase of the two-dimensional Ising model.
Predicting mortality in stroke.
Bhalla A,Gupta O,Gupta S
Neurology India , 2002,
Abstract: Physicians are faced with the task of predicting the immediate and long term outcome in stroke patients. It is also important to efficiently and optimally utilize resources. We used APACHE III scoring system or predicting in hospital outcome in patients with stroke. We found it to be sensitive (>90%) and resonably specific (73%) in predicting short term, in-hospital mortality, in our study group.
