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)
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)
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 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)
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)
BACKGROUND Lymphomatoid papulosis (LyP) is a lymphoproliferative disorder that is rare among adults and even rarer among children. In adults, LyP is associated with an increased risk of secondary lymphomas. OBJECTIVE The aim of this systematic review was to describe the clinical and histopathological features of LyP in children, to assess the risk of(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)
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)
Granulomatous mycosis fungoides (GMF) is a rare form of mycosis fungoides (MF) characterized by an infiltrate of atypical lymphocytes, histiocytes, and multinucleated giant cells. Clinically, GMF has a slowly progressing course with a worse prognosis than other forms of MF. With its peak incidence being in the fifth to sixth decade, GMF is rare in children(More)
With respect to wound ballistics, the situation is different if the person wearing a military helmet suffers head injuries from a bullet. The mechanisms of injury were investigated in four experimental series and supplemented by a case history. The study showed surprising results: in the majority of cases, the helmet does not protect the wearer, but instead(More)
