BACKGROUND Thumb sucking habits make up the majority of oral habits. While thumb sucking is considered normal during the first two years of life, if it is not controlled and persists beyond the preschool period it may cause deleterious effects on dentofacial structures. Reminder therapy using Bluegrass appliance has been proven successful to intercept thumb sucking habit. CASE REPORT We prese...

TRAUMATIC amputation of the thumb is a particularly severe hand injury, because of the unique functional role of the thumb, and several methods exist for reconstruction of the thumb, all of which have disadvantages. Microvascular technique allows the transfer of a block of tissue from one site to another, by anastomosis of vessels with a known vascular territory to the vessels in the recipient ...

The aim of this study is to establish whether the thumb is represented independently of the palm. An exogenous spatial cueing paradigm was used, where participants had to detect a tactile stimulus that could appear on the proximal and distal phalanges or metacarpus of the thumb (thenar area; Experiment 1) and the metacarpus of the thumb or hypothenar area of the palm (Experiment 2) of the left ...

Bowler's thumb is a rare perineural fibrosis involving the ulnar digital nerve of the thumb. Affected patients present with pain, neuropathy, and mass lesion. The condition is caused by chronic repetitive impaction of the ulnar soft tissues of the thumb against the thumbhole of a bowling ball. In our case, MRI showed decreased signal intensity on both T1- and T2-weighted images surrounding an e...

Deafferentation such as the amputation of a body part causes cortical reorganization in the primary motor cortex (M1). We investigated whether this reorganization is reversible after reconstruction of the lost body part. We tested two patients who had long-standing thumb amputations followed by thumb reconstruction with toe-to-thumb transfer 9 to 10 mo later and one patient who underwent thumb ...

In the heterometallic dinuclear title compound, [CuNa(C(24)H(22)N(2)O(4))Cl(H(2)O)]·C(3)H(7)NO, the Cu(II) ion is coord-inated in a square-planar geometry by two N atoms and two O atoms of the 6,6'-dieth-oxy-2,2'-[1,2-phenyl-enebis(nitrilo-methyl--idyne)]diphenolate ligand. The Na(I) ion is hexa-coordinated by four O atoms of the ligand, defining the equatorial plan, and by one O atom of the wa...

[1] Recent Geotail and Cluster observations revealed that thin current sheets in the near-Earth tail may have a bifurcated structure. In some cases the electrons are found to dominate the current. We present a generalization of the Harris current sheet equilibrium, which reproduces these features. The model ion distribution contains an additional element, viz. the quasi-adiabatic invariant of t...
