Obscure gastrointestinal bleeding: capsule endoscopy versus computerized tomography.
In the study of the Turkish Journal of Gastroenterology mentioned above, the number of cases seems too small to arrive at the mentioned conclusions, and it is said that 90% of these cases have obscure overt bleeding. In common practice, we usually perform capsule endoscopy for occult obscure bleeding much more frequently than for overt obscure bleeding. That is why I think that this ratio of 90...
متن کاملSIMPLE LIGATION VERSUS STUMP INVAGINATION DURING APPENDICECTOMY-A PROSPECTIVE TRIAL
A prospective, randomized trial on 416 consecutive cases of appendicectomies was carried out in which half of the cases had simple ligation of the stump and the rest had invagination of the stump in addition. The two groups were matched for age, sex, state of personal hygiene and nutrition. The incidence of wound infection, and early and late post-operative complications remained comparabl...
متن کاملZeno phenomena : pulsed versus continuous measurement
The time evolution of an unstable quantum mechanical system coupled with an external measuring agent is investigated. According to the features of the interaction Hamiltonian, a quantum Zeno effect (hindered decay) or an inverse quantum Zeno effect (accelerated decay) can take place, depending on the response time of the apparatus. The transition between the two regimes is analyzed for both pul...
متن کاملBohmian versus semiclassical description of interference phenomena
The origin of quantum interference characteristic of bound nonlinear systems is investigated within the Bohmian formulation of time-dependent quantum mechanics. By contrast to time-dependent semiclassical theory, whereby interference is a consequence of phase mismatch between distinct classical trajectories, the Bohmian, fully quantum mechanical expression for expectation values has a quasiclas...
متن کاملBest-E ort versus Reservations: A Simple Comparative Analysis
Using a simple analytical model, this paper addresses the following question: Should the Internet retain its best-e ort-only architecture, or should it adopt one that is reservation-capable? We characterize the di erences between reservation-capable and best-e ort-only networks in terms of application performance and total welfare. Our analysis does not yield a de nitive answer to the question ...
