Superior sulcus tumours are rarely encountered in clinical practice, representing < 5% of all bronchogenic carcinomas [1, 2]. In 1932, Pancoast [3] published his classic article in which he reported four patients who had a similar presentation including pain in the shoulder and arm, weakness and wasting of the muscles of the hand, and ipsilateral Horner syndrome together with a lesion situated ...

New methodologies are designed to reduce the time complexity of an implicit discrete-time differentiator and simulation implement it. They rely on Horner’s method Shaw-Traub algorithm. The algorithms compared for differentiators order 3, 7, 10. Half-Horner Full-Horner methods showed best performance complexity.

A patient undergoing left mastectomy and immediate latissimus dorsi breast reconstruction under combined paravertebral block and general anaesthesia developed transient, well-demarcated, right-sided hemifacial erythema and sweating, and left-sided Horner syndrome postoperatively. This "harlequin" appearance occurs because of a normal or excessive vasodilatory, thermoregulatory response to heat ...

A 50-year-old woman presented with left-sided Horner syndrome that had occurred after an extensive scuba dive 10 days before. Ultrasound of the cervical arteries showed a homogeneous, moderately echolucent, excentric thickening of the left internal carotid artery wall (the Figure, A), findings that were strongly suggestive of a several-dayold intramural carotid hematoma associated with carotid ...

healthy 58-year-old woman had undergone arthrosopy of both temporomandibular joints because of ilateral mandibular clicks and recurrent episodes of aw block that did not respond to nonsurgical treatent. The preoperative examination showed general estriction of mandibular motility (maximal oral aperure 26 mm, right and left lateral deviation 11 and 8 m, respectively, protrusion 10 mm, and dental...
