purpose: to report two patients with keratoconus who underwent regrafting to correct anisometropia and high astigmatism after penetrating keratoplasty. patients and findings: the first case is a 34-year-old man with keratoconus who had undergone penetrating keratoplasty. the sutures were removed 6 months postoperatively that led to high hyperopia. regraft was performed considering vitreous leng...

Three patients developed symptoms suggestive of acute schizophrenia. In each case there were no abnormal neurological findings on admission to hospital. Within a few days clinical evidence of encephalitis became apparent, and appropriate treatment was given. Only one patient made a full recovery.

asri@interchange Summary Periprosthetic fractures are increasing in number and complexity. Appropriate precautions should be taken to prevent these fractures. A systematic approach is needed in the form of detailed assessment of the fracture, stability of the implant and the available bone stock for planning an appropriate treatment. The treatment options described in this article can be used a...

Traditional views on facial aging and associated therapies focused on soft tissue descent and skin texture changes. Recently, revolumization for age-related lipoatrophy has become increasingly popular. Researchers are now reporting objective studies examining processes of structural and volumetric changes with age in increasing frequency as well. To better understand and treat facial aging, the...

In this paper a redundancy allocation problem is studied where for the first time the supplier selection is taken into consideration and redundant components are provided from appropriate suppliers with the most suitable offers such as discount on buying price of components, warranty length for components, things like that, so that the system reliability, profit and the warranty length proposed...

The challenge of recognising the ward-based patient at risk of rapid deterioration is discussed frequently within the literature. As their role enables them to be in constant contact with patients, nurses are in a prime position to identify problems at an early stage with the use of systematic patient assessment. This means appropriate treatment can be initiated quickly, potentially saving the ...

In this study, Stability analysis of snow slab which is under detonation has developed in the present model. The model has been studied by using the basic concepts of non-detonation model and concepts of underwater explosions with appropriate modifications to the present studies. The studies have also been extended to account the effect of critical length variations at the time of detonation an...

For two permutations o and u on disjoint sets of integers, consider forming a permutation on the combined sets by "shuffling" o and u (i.e., a and co appear as subsequences). Stanley [10], by considering P-partitions and a g-analogue of Saalschutz's 3F2 summation, obtained the generating function for shuffles of o and u with a given number of falls (an element larger than its successor) with re...
