BACKGROUND Lymphomatoid papulosis (LyP) is a CD30(+) lymphoproliferative disorder, with a self-regressing clinical course and malignant histopathology. OBJECTIVE The aim of this study was to evaluate characteristics, risk factors, associated malignancies, long-term outcome, and treatment of LyP in a large cohort representing the experience of the MD(More)
PURPOSE Escherichia coli 83972 was previously shown to establish bladder colonization in select patient groups. We evaluate the safety and feasibility of using bacterial interference with E. coli 83972 to prevent urinary tract infection in spinal cord injured patients. MATERIALS AND METHODS A total of 21 men and women with neurogenic bladder secondary to(More)
Little is known about bacteria associated with asymptomatic bacteriuria (ABU) with regard to urinary tract colonization mechanisms. In this study, virulence properties of Escherichia coli 83972, a strain that was isolated from a clinical ABU episode, were examined. The genetic potential for expression of P and type 1 pili was demonstrated, and DNA sequences(More)
BACKGROUND Leonine facies (LF) is defined as displaying facial features similar to that of a lion with prominent convexities and furrowed creases. LF develops in a very small population of patients with cutaneous T-cell lymphoma. OBJECTIVE We aimed to study the clinicopathologic features and overall prognosis associated with LF in patients with mycosis(More)
Chronic bacteriuria is a common occurrence among spinal-cord injury patients and others with neuropathic bladders. If bacteria are present in the urinary tract, the patient may develop symptoms of infection or remain asymptomatic. We have compared virulence properties of 28 Escherichia coli isolates from patients with symptomatic urinary tract infections(More)
—Recent work has shown the feasibility of pedestrian and robotic indoor localization based only on maps of the magnetic field. To obtain a complete representation of the magnetic field without initial knowledge of the environment or any existing infrastructure, we consider an autonomous robotic platform to reduce limitations of economic or operational(More)
We present a robust and scalable algorithm to enable multiple robots to efficiently explore previously unknown environments. Applications of this algorithm include but are not limited to the exploration of scalar (e.g. concentration of a chemical substance) or vector fields (e.g. direction and intensity of the magnetic field). As opposed to previous works,(More)
OBJECTIVES Fetal aortic valvuloplasty can improve filling and reduce afterload of the left ventricle in critical aortic stenosis. Success of an intrauterine intervention is currently measured by technical success, clinical survival and eventual postnatal biventricular physiology. In the present study we investigated the use of tissue Doppler imaging (TDI)(More)
OBJECTIVE Adverse childhood experiences, such as maltreatment, and affective disorders are associated with a proinflammatory state and/or variably compromised counts in lymphocyte subsets in adults. Animal models of social stress indicate that recent thymic emigrant cells (RTE), which maintain the T-cell compartment, are affected. METHODS In this study,(More)
