We report the case of a 46-year-old female patient who was referred to our clinic (Orasis Eye Clinic, Reinach, Switzerland) seeking improvement of her distance and near visual acuity. Radial keratotomy (RK) was performed at a younger age on both eyes to correct -5 D myopia. The patient underwent a bilateral same-session multifocal corneal excimer femtosecond laser (Supracor) keratomileusis corr...

BACKGROUND The purpose of this study was to present a novel surgical technique using an on-top osteotomy and to assess the clinical and radiographic outcomes for the triphalangeal Wassel type VI thumb duplication patients. METHODS The surgical technique involves ablation of the radial thumb at distal one-third of the metacarpal, corresponding metacarpal osteotomy of the ulnar thumb, with amal...

Radial glia are a polarized cell type that in most neural regions appear only transiently during development. They have long been recognized as glia or glial progenitors that support neuronal migration. Recent evidence indicates that radial glia also give rise to neurons and appear to be a major population of dividing precursor cells in the embryonic cortical ventricular zone. Radial glia exten...

Ulnar nerve compression at wrist is manifested either pathologically due to ganglia or neoplasms, or anatomically by the presence of accessory muscles in the hypothenar region. Accessory abductor digiti minimi muscle is an additional muscle encountered rarely in the wrist; presence of which causes high risk of ulnar neuropathy. We report here a case of unilateral accessory abductor digiti minim...

Wavelets and radial basis functions (RBF) are two rather distinct ways of representing signals in terms of shifted basis functions. An essential aspect of RBF, which makes the method applicable to non-uniform grids, is that the basis functions, unlike wavelets, are non-local|in addition, they do not involve any scaling at all. Despite these fundamental di erences, we show that the two types of ...

In this paper, we present a numerical method for solving Hallen’s integral equation based on radial basis functions (RBFs). This method will represent the solution of Hallen’s integral equation by interpolating the radial basis functions based on Legendre-Gauss-Lobatto(LGL) nodes and weights. The numerical results show that the proposed method for Hallen’s integral equation is very accurate and...

In this report an algorithm for the fast reconstruction of a textured 3-D face model of the given individual from his two orthogonal pictures – a frontal view and a profile view is presented. Then a possible application to the facial makeover of the individual is also conceptualized. The algorithm needs minimal human intervention for construction and does not need any special setup, or the came...

INTRODUCTION SPOAN (spastic paraplegia, optic atrophy, and neuropathy) syndrome is an autosomal recessive neurodegenerative disorder identified in a large consanguineous Brazilian family. METHODS Twenty-seven patients with SPOAN syndrome (20 women), aged 4-58 years, underwent nerve conduction studies (NCS) of the median, ulnar, tibial, and fibular nerves, and sensory NCS of the median, ulnar,...

In dystrophic mice, a model of merosin-deficient congenital muscular dystrophy, laminin-2 mutations produce peripheral nerve dysmyelination and render Schwann cells unable to sort bundles of axons. The laminin receptor and the mechanism through which dysmyelination and impaired sorting occur are unknown. We describe mice in which Schwann cell-specific disruption of beta1 integrin, a component o...

OBJECTIVES The influence of regular and intense practice of an asymmetric sport such as tennis on nerves in the elbow region was examined. METHODS The study included 21 male elite tennis players with a mean (SD) age of 27.5 (1.7) years and 21 male non-active controls aged 26.4 (1.9) years. Anthropometric measurements (height, weight, limb length, and perimeters of arm and forearm) were determ...
