Sufficient cause interactions concern cases in which there is a particular causal mechanism for some outcome that requires the presence of 2 or more specific causes to operate. Empirical conditions have been derived to test for sufficient cause interactions. However, when regression outcome models are used to control for confounding variables in tests for sufficient cause interactions, the outc...

introduction wilson’s disease is an autosomal recessive disorder, characterized by a disturbance in copper metabolism that leads to copper overload in different tissues of the body. because of various manifestations of wilson’s disease, physicians should have high index suspicion when patients manifest any type of liver disease, neurologic and psychiatric signs and symptoms. discussion wilson’s...

conclusions significant improvement was noted at womac scale (pain level; 5 points, stiffness level; 2 points, physical function loss; 15 points, and total womac 22 points). osteoarthritis level of the patient was improved to grade i at radiological evaluation after a year. our case is the report that presents radiological evidence in addition to clinical findings of improvement of osteoarthrit...

In this paper we present the use of ontology for knowledge representation and handling in Software Agent Systems. Motivation has come from Pellucid IST project where we need to capture and capitalize employee’s knowledge in organization. This knowledge is then presented to other employees as they work on particular tasks. The Protg ontology editor and JADE multi-agent system is used for impleme...

A 16-year-old female with juvenile idiopathic arthritis presented with a one-month history of decreasing vision and increasing corneal edema in her left eye. Slit-lamp examination, keratometric measurements, and OCT evaluation led to a diagnosis of Terrien's marginal degeneration in both eyes along with a complete detachment of Descemet's membrane in the left eye and partial detachment in the r...

A 33-year-old man had dizziness for 3 days without provoking factors. Head CT demonstrated a mass in the left lateral anterior cranial fossa with calcification and cystic degeneration (figure 1, A–C). MRI showed an irregularly shaped mass with mixed signal and slight marginal enhancement (figure 1, D–F). He underwent mass resection with no recurrent dizziness during 12 months’ follow-up. On pat...

We present a patient with marginal corneal degeneration and corneal astigmatism of more than 10.0 diopters (D). A toric phakic intraocular lens (IOL) of 7.0 D cylindrical power was implanted in both eyes to correct the high astigmatism. An uncorrected visual acuity of 20/40 was achieved in both eyes, and the best corrected visual acuity improved by 4 Snellen lines to 20/20 in both eyes. Refract...

statement of problem: targis restorations provide good esthetic and clinical success; however, improving marginal accuracy requires further investigations. purpose: the aim of this was to study evaluate the effect of relining on the marginal accuracy of ceromer crowns. material and methods: one ivorine maxillary central incisor was prepared for targis crown. 10 acrylic models were duplicated fr...
