    Notes: Abstract Background: The purpose of this study was to investigate the imaging findings in patients with familial Mediterranean fever (FMF) during and between acute attacks. Methods: Computerized search of medical records from 1989 to 1998 identified 139 patients with a discharge diagnosis of FMF. Medical records, imaging studies, and pathologic findings were reviewed. Results: Sixty-eight patients had a documented acute attack of FMF, and 71 patients known to have FMF were asymptomatic. Imaging was performed in 68 patients. Radiologic findings included ascites, splenomegaly, hepatomegaly, lymphadenopathy, focal peritonitis, peritoneal cysts, renal changes, and other incidental findings. Conclusions: Radiologic findings in symptomatic and asymptomatic FMF patients are not uncommon. Imaging in selected cases may facilitate diagnosis and show complications.

    Notes: Abstract A rare case of torsion of the gallbladder fundus, which was diagnosed by ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) and released during ERCP, is presented. The case illustrates the sonographic and ERCP findings of this rare condition and suggests using ERCP as a therapeutic tool.

    Notes: Abstract This paper presents a two-field mixed finite element formulation in the time domain. Several strategies are presented by which the variational formulations are produced. One strategy is based on Hamilton's law, and is suitable for problems where the mechanical energy of the system is given. Another strategy uses the Galerkin method, which is suitable when the equations of motion are given. This strategy can either be based on a continuous or discontinuous approximation of the physical variables in time. All formulations were analyzed, and their characteristics in terms of truncation error (phase and amplitude) and stability are presented. This analysis was verified by numerical results. Comparison of many formulations leads to the conclusion that discontinuous mixed finite element method in the time domain is superior to all others in terms of stability and accuracy.

    Notes: Granulosa cells, which nurse the oocyte and serve as a major source for estradiol and progesterone production, undergo major morphological changes which correlate very well with modulation of their steroidogenic capacity. These include changes in intercellular contacts and communication, in cell membrane receptors, and in the development and organization of organelles associated with steroidogenesis (i.e., mitochondria, smooth endoplasmic reticulum, lipid droplets, and lysosomes). These biochemical and morphological changes can also be obtained in primary cultures as well as in oncogene transformed granulosa cell lines established recently in our laboratory. A growing body of evidence suggests that plasticity of the cytoskeleton plays a major role in the biochemical and morphological differentiation of granulosa cells as well as in other steroidogenic cells. © 1994 Wiley-Liss, Inc.
