This paper investigates the applicability of User Interaction Diagrams (UIDs) as user scenarios for specifying requirements of software built by non-technical customers. User scenarios represent an alternative to representation of Acceptance Test-Driven Development (ATDD). Two methods for building user scenarios using UIDs were proposed: the progressive and the regressive methods. The progressi...

We reviewed 6 patients with atlanto-axial (C1-2) deformities secondary to neglected odontoid fractures. All patients (except one with recent injury) were asymptomatic for a long period before development of neck pain or myelopathy, despite obvious subluxation and kyphotic deformities at the C1-2 joint complex. Patients were treated conservatively, except for one who underwent posterior spinal f...

Non-alcoholic fatty liver had been believed to be a non-progressive benign disease. However, Ludwig et al. described some patients who exhibited progressive steatohepatitis without habitual alcohol drinking (Ludwig et al., 1980) and referred to this disease as non-alcoholic steatohepatitis (NASH). Later, NASH and non-progressive simple steatosis patients were included in the single disease enti...

radiological findings of 20 patients with scleroderma have been described. we had cornmon and uncommon roentgen signs of scleroderma similar to other series and one case with mid esophagus narrowing which we think have not been reported previously.

nethertons syndrome consists of the combination of ichthyosis, eczema, and abnormal hair and presents within the first 10 days of life with erythroderma. other reported features are short stature, mental retardation, and seizures. allergy to nuts and fish is also common amongst patients. mutations in the spink5 gene on 5q are reported in patients with nethertons syndrome. to the best of our kno...

crestal bone loss is a biological complication in implant dentistry. the aim of this study was to compare the effect of progressive and conventional loading on crestal bone height and bone density around single osseointegrated implants in the posterior maxilla by a longitudinal radiographic assessment technique.twenty micro thread implants were placed in 10 patients (two implants per patient). ...

A patient with progressive visual loss and macular hole development due to progressive myopic traction maculopathy was studied using spectral domain optical coherence tomography (SD-OCT). A characteristic, deep retinal schisis-like change was clearly demonstrable. Progression to a full-thickness macular hole was documented. Postoperatively, the macular hole was closed, and the visual acuity was...
