Bifid Median Nerve in Carpal Tunnel Syndrome: Assessment with US Cross-sectional Area Measurement
No full textTo evaluate the accuracy of ultrasonography (US) in the diagnosis of carpal tunnel syndrome (CTS) in patients with a bifid median nerve on the basis of cross-sectional area (CSA) measurements of the median nerve at the level of the carpal tunnel (CSAc), with additional measurements obtained more proximally (CSAp) at the level of the pronator quadratus muscle.This HIPAA-compliant study was approved by the local institutional review board; informed oral and written consent were obtained. Fifty-three wrists in 49 consecutive patients with a bifid median nerve and CTS symptoms and 28 wrists in 27 healthy volunteers with a bifid median nerve were examined by using US. Two independent US examiners who were blinded to prior test results measured median nerve CSA at two levels, CSAc and CSAp. The difference between CSAc and CSAp (ΔCSA) was calculated for each wrist. Receiver operating characteristic (ROC) analysis was performed.The study population included 17 men and 32 women (mean age, 55.1 years; age range, 24-78 years). The control population included 13 men and 14 women (mean age, 52.6 years; age range, 24-86 years). Mean CSAc was approximately 5 mm(2) greater in patients with CTS than in healthy volunteers (P < .0001), while mean ΔCSA was 5.8-5.9 mm(2) greater in patients with CTS (P < .0001). A CSAc threshold of 12 mm(2) provided sensitivity and specificity of 84.9\% and 46.5\%, respectively, while a ΔCSA threshold of 4 mm(2) provided sensitivity and specificity of 92.5\% and 94.6\%, respectively. ROC analysis demonstrated a significant advantage of ΔCSA (area under ROC curve [A(z)] = 0.95-0.96) compared with CSAc (A(z) = 0.84-0.85) for the diagnosis of CTS (P < .003).The use of a ΔCSA parameter improves the diagnostic accuracy of US for the presence of CTS in patients with a bifid median nerve
Cross-generational Differences in Spatial Language in aṣ-Ṣāniʿ Arabic
No full textI compare linguistic representations of projective spatial relations in two varieties of aṣ-Ṣāniʿ Arabic: Traditional aṣ-Ṣāniʿ Arabic (TAA), spoken by those over age 67, and New aṣ-Ṣāniʿ Arabic (NAA), spoken by the rest of the tribe. My comparison pertains to spatial prepositions and Frames of Reference (FoRs). FoRs – Intrinsic/Relative/Absolute ̶ are semantic strategies used to project coordinate systems onto spatial arrays in order to locate an object F (figure) in relation to another object G (ground) (Levinson 2003). TAA selects the appropriate FoR in context in accordance with Gs’ cultural properties and axial constraints: Intrinsic FoR applies only to [+FAMILIAR][+SHAPED] Gs (man/horse/camel/tent/coffee-pot) with prepositions giddām/gabl/(ʿa)wijh, while (ʿa)wijh/gabl serve when FG [+FACING-EACH-OTHER] and giddām when FG [-FACING-EACH-OTHER]. Relative FoR is applied via Translation to [+FAMILIAR][-SHAPED] Gs (stone/tree/pole/pillow); Absolute FoR is used with [-FAMILIAR] Gs (cow/dinosaur/shoe/chair). Relative and Absolute FoRs are represented by two grammatical strategies: basic prepositions (F wara/šarg G) and “min-chains” (F min G w-ǧāy/ġād/šarg) following Gs and axial distinctions. Each FoR correlates exclusively to certain prepositions (prepositional split). NAA loses traditional ontology of Gs and axial oppositions; prepositional split regresses: gabl applies only when FG [+HUMAN][+FACING-EACH-OTHER]; giddām/(ʿa)wijh serve Intrinsic and Relative FoRs, on all Gs, without axial constraints; Absolute FoR is used only on geographic scale; Relative FoR is applied via Translation and Reflection; the opposition between basic prepositions vs. min-chains in Absolute and Relative FoRs disappears, as min-chains vanish. Beginning with the establishment of the State of Israel and through the early 1950s, the generational gap between TNA and NAA shows how material culture, formal education, language contact, and life style modify the semantics of space and its experience
