A clinically applicable and accurate method for measuring Achilles tendon length is needed to investigate the influence of elongation of the Achilles tendon after acute rupture. The purpose of this study was to develop and validate an ultrasonographic (US) length measurement of the Achilles tendon-aponeurosis complex. Both legs of 19 non-injured subjects(More)
To the Editor: Renal sympathetic denervation (RDN) has been dopted in a number of countries as an additional treatment option o supplement antihypertensive therapy in patients with resistant ypertension. Concerns have been raised with regard to the ossible occurrence of renal artery stenosis (RAS). In the followng, we present a case of RAS as the(More)
BACKGROUND Most surgeons don't repair the pronator quadratus (PQ) muscle in palmar plate fixation of a distal radius fracture because experience has shown that PQ repair yields no functional advantage. However, repair of the PQ may offer finger flexor tendon protection. METHODS In 9 human cadavers, the PQ was detached with a strong rim of connective(More)
Juvenile hormone III (JHIII), when applied to the abdomen of 1-day-old female Acheta domesticus (in quantities that would create JHIII titers in the hemolymph that were within the range measured in females of this species) caused a significant decrease in phonotactic thresholds (Fig. 1). Removal of the corpora allata from 5-day-old females with low(More)
To investigate whether compression of the superior mesenteric vein (SMV) on computed tomography (CT) can serve as a valid sign of internal herniation (IH) in patients with antecolic laparoscopic Roux-en-Y gastric bypass (LRYGBP). With institutional review board approval, we performed a retrospective analysis of 41 patients with antecolic LRYGBP referred for(More)
BACKGROUND In open reduction and volar plate fixation of distal radius fractures, the pronator quadratus (PQ) muscle is usually detached at the radial edge of the distal radius. Repair of the muscle is reasonable for coverage of the plate and to maintain normal pronation of the forearm. However, repair of the muscle is not always satisfactory. In this(More)
The saliva of patients with acute labyrinthopathies (sudden deafness, M. Meniere) was gained by draining both of Stens' ducts with an ethylene tube. The saliva was collected every minute and the concentrations of sodium, potassium, calcium, amylase and total proteins was performed in every specimen. In most cases the salivary flow rate was reduced and the(More)
