Prof. Pedro Planas of Spain initially developed PDTs,1 and Simoes11 adapted them for early prevention of anterior or posterior crossbite. PDTs should be used in the deciduous dentition only, as they cover the occlusal surfaces of the molars, resulting in a flat posterior occlusion until the molars are exfoliated. PDTs can be built in the laboratory using an indirect technique. A wax bite regist...

Introduction: Functional MRI methods have been used to study sensorimotor processing in the Spinal cord. However, these techniques confront unwanted contributions to the measured signal from the physiological fluctuations. For the spinal cord imaging, most of the challenges are consequences of cardiac and respiratory movement artifacts that are considered as significant sources of noise, especi...

MANY ingenious closed or blind technics have been devised and enthusiastically advocated in the recent past for the surgical correction of mitral regurgitation. Invariably, success was transitory and such operations were short lived, to be replaced sinmilarly by others. During the past 3 years we have operated upon 82 patients with varying degrees of mitral insufficieney by the open-heart tech-...

OBJECTIVES We investigated whether anodal transcranial direct current stimulation over the left dorsolateral prefrontal cortex affected the working memory performance of patients after a stroke. DESIGN Ten patients (mean age 47.7 yrs) with cognitive deficits after a first-ever stroke participated in this single-blind, crossover, and sham-controlled experiment. Each patient was randomly assign...

The unequal error correction capabilities of binary cyclic codes of composite length aye investigated. Under certain conditions, direct sums of concatenated codes have unequal error correction capabilities. By a modified Hartmann and Tzeng algorithm, it is shown that a binary cyclic code of composite length is equivalent to the direct sum of concatenated codes. With this, some binary cyclic une...

The correction of functional posterior crossbite through Planas Direct Tracks has many characteristics that can become advantages. The aim of this study was to present a clinical case showing how to use this procedure for early correction with resources available through public health services. The patient, a 4-year-old girl, arrived to receive treatment due to a functional unilateral crossbite...

The coronary arteries are a major concern in anatomical correction of d-transposition of the great arteries. The necropsy study was undertaken to assess the feasibility of direct bilateral reimplantation as described by Fatene et al. This seemed possible in only 30 per cent of 100 cases, and furthermore was related to the type of coronary artery pattern.
