NeXTSTEP (also stylized as NeXTstep, NeXTStep, and NEXTSTEP) is a combination of several parts: a Unix operating system based on the Mach kernel, plus source code from BSD Display PostScript and a proprietary windowing engine the Objective-C language and runtime an object-oriented (OO) application layer, including several ''kits'' development tools for the OO layers NeXTSTEP is notable for having been a preeminent implementation of the latter three items.
answer:
What is the programming language for NeXTSTEP?

question:
Restless legs syndrome (RLS), recently renamed Willis-Ekbom disease (WED), is a common movement disorder. It is characterised by the need to move mainly the legs due to uncomfortable, sometimes painful sensations in the legs, which have a diurnal variation and a release with movement. Management is complex. First, centres should establish the severity of RLS using a simple 10-item RLS severity rating scale (IRLS). They should also exclude secondary causes, in particular ensuring normal iron levels. Mild cases can be managed by lifestyle changes, but patients with a IRLS score above 15 usually require pharmacological treatment. Dopaminergic therapies remain the mainstay of medical therapies, with recent evidence suggesting opioids may be particularly effective. This article focuses on the different treatment strategies in RLS, their associated complications and ways to manage them.

question:
De Quervain's disease has different clinical features. Different tests have been described in the past, the most popular test being the Eichhoff's test, often wrongly named as the Finkelstein's test. Over the years, a misinterpretation has occurred between these two tests, the latter being confused with the first. To compare the Eichhoff's test with a new test, the wrist hyperflexion and abduction of the thumb test, we set up a prospective study over a period of three years for a cohort of 100 patients (88 women, 12 men) presenting spontaneous pain over the radial side of the styloid of the radius (de Quervain tendinopathy). The purpose of the study was to compare the accuracy of the Eichhoff's test and wrist hyperflexion and abduction of the thumb test to diagnose correctly de Quervain's disease by comparing clinical findings using those tests with the results on ultrasound. The wrist hyperflexion and abduction of the thumb test revealed greater sensitivity (0.99) and an improved specificity (0.29) together with a slightly better positive predictive value (0.95) and an improved negative predictive value (0.67). Moreover, the study showed us that the wrist hyperflexion and abduction of the thumb test is very valuable in diagnosing dynamic instability after successful decompression of the first extensor compartment. Our results support that the wrist hyperflexion and abduction of the thumb test is a more precise tool for the diagnosis of de Quervain's disease than the Eichhoff's test and thus could be adopted to guide clinical diagnosis in the early stages of de Quervain's tendinopathy.
