BACKGROUND Cutaneous T-cell lymphomas (CTCLs) rarely arise before 30 years of age; therefore the characteristics of these lymphomas are largely unknown. OBJECTIVE Our purpose was to assess the clinical and pathologic aspects of CTCL in young persons. METHODS We identified nine patients who had epidermotropic CTCL by 30 years of age and analyzed their(More)
BACKGROUND Mycosis fungoides-type cutaneous T-cell lymphoma is uncommon in association with human immunodeficiency virus type 1 (HIV-1) infection. Reported patients have a high incidence of CD8+ T-cell lymphomas and erythroderma, are usually severely immunocompromised, and rapidly die. Chronic, more typical patch-plaque mycosis fungoides-type cutaneous(More)
The human hand uses a combination of feedforward and feedback mechanisms to accomplish high degree of freedom in grasp control efficiently. In this study, we used a synergy-based control model to determine the effect of sensory feedback on kinematic synergies in the grasping hand. Ten subjects performed two types of grasps: one that included feedback (real)(More)
Kinematic and neuromuscular synergies have been found in numerous aspects of human motion. This study aims to determine how effectively kinematic synergies in bilateral upper arm movements can be used to replicate complex activities of daily living (ADL) tasks using a sparse optimization algorithm. Ten right-handed subjects executed 18 rapid and 11(More)
Kinematic synergies in human hand movements have shown promising applications in dexterous control of robotic and prosthetic hands. We and others have previously derived kinematic synergies from human hand grasping movements using a widely used linear dimensionality reduction method, Principal Component Analysis (PCA). As the human biomechanical system is(More)
Aggressive B-cell non-Hodgkin's lymphoma frequently complicates human immunodeficiency virus type 1 infection. Although extranodal disease is an important feature of this condition, the incidence of cutaneous involvement has not been determined. A review of 754 published cases of B-cell non-Hodgkin's lymphoma associated with human immunodeficiency virus(More)
Recently, the need for more secure identity verification systems has driven researchers to explore other sources of biometrics. This includes iris patterns, palm print, hand geometry, facial recognition, and movement patterns (hand motion, gait, and eye movements). Identity verification systems may benefit from the complexity of human movement that(More)
BACKGROUND The controversial nosology of Woringer-Kolopp disease (localized pagetoid reticulosis, unilesional mycosis fungoides) is being clarified by the systematic immunophenotypic and immunogenetic examination of infiltrating lesional T lymphocytes. The clinical course and immunohistochemical characteristics of eight cases of Woringer-Kolopp disease are(More)
