BACKGROUND The purpose of this study was to present the feasibility of reconstructing an inferior orbital rim and cheek defect with a pedicled osteomyocutaneous submental flap. METHOD A 77-year-old women with a right nasosinusal adenoid cystic carcinoma invading soft tissues and skin of the cheek, the inferior rim of the orbit, the hard palate, and the middle turbinate is presented. A right r...

We present a case of a 59-y-old woman who had undergone cholecystectomy and was subsequently found to have an abscess within the gallbladder fossa. A hepatobiliary scan using (99m)Tc-diisopropyliminodiacetic acid demonstrated the characteristic rim sign, a photopenic defect surrounded by a rim of mildly increased activity immediately adjacent to the gallbladder fossa. The rim sign was thought t...

BACKGROUND In patients with femoroacetabular impingement (FAI), acetabular rim trimming removes the offending area of the acetabular deformity in patients with pincer-type and mixed-type FAI to improve hip joint kinematics. Although the rationale for arthroscopic acetabular rim trimming in patients with FAI is well established, the amount of rim resection has not been quantified, and the thresh...

The Rim-Driven Thruster (RDT) is an extraordinary innovation in marine propulsion applications. structure of RDT resembles a Ducted Propeller (DP), as both contain several propeller blades and duct shroud. However, unlike the DP, there no tip clearance directly connected to rim. Instead, gap exists between rim duct. distinctive difference DP causes significant discrepancy performance flow featu...

BACKGROUND AND PURPOSE No highly specific MR imaging features distinguishing ISCMs from primary cord masses have been described. Our purpose was to retrospectively compare peripheral enhancement features on postgadolinium MR imaging of ISCMs with primary intramedullary cord masses. MATERIALS AND METHODS A consecutive group of patients with firmly diagnosed ISCM (45 patients with 64 ISCMs) and...

Active zone proteins play a fundamental role in regulating neurotransmitter release and defining release sites. The functional roles of active zone components are beginning to be elucidated; however, the mechanisms of active zone protein localization are unknown. Studies have shown that glutamine, leucine, lysine, and serine-rich protein (ELKS), a recently defined member of the active zone comp...

AIMS Progressive loss of neuroretinal rim tissue is known to occur early in glaucoma and measurement of the neuroretinal rim area is possible by magnification corrected analysis of optic disc photographs (planimetry). This study was performed to determine whether the facility to distinguish between glaucomatous and normal optic discs could be improved upon by: (a) taking into account the known ...
