“An 81-year-old woman presented with symptoms of recurrent urinary tract infections, urge incontinence and nocturia. Cystoscopy performed revealed a whitish plaque lesion on the fundus and right lateral wall of the bladder. The histology of the biopsy confirmed the diagnosis of leukoplakia vesicae of the bladder. The plan is to follow her up with repeat
cystoscopy and biopsy in 6 months. The literature search revealed very little information on the pathogenesis and prognosis of this condition due to its rare occurrence. Analysis of the literature signifies the association of chronic irritation due to recurrent urinary tract infections Selisistat in vivo being the commonest cause of leukoplakia vesicae. The recommended long-term follow-up and surveillance based on the literature review is by cystoscopy with or without biopsy.”
“Macroscale thermal models for biological
tissues can be developed either by the mixture theory of continuum mechanics or by the porous-media theory. Characterized by its simplicity, the former applies scaling-down from the global scale. The latter uses scaling-up from the microscale by the volume averaging, thus offers the connection between microscale and macroscale properties and is capable of describing the rich blood-tissue interaction in biological tissues. By using the porous-media approach, a general bioheat transport model is developed with the required closure provided. Both blood and tissue macroscale temperature fields are shown to satisfy the dual-phase-lagging (DPL) energy equations. Thermal waves and possible resonance may appear due to the coupled conduction between blood and tissue. For the DPL bioheat transport, contributions of the initial temperature distribution, the source term and the initial rate of change of temperature are shown to be inter-expressible under linear boundary conditions. This reveals the solution structure and considerably simplifies the development of
solutions of the DPL bioheat equations. Effectiveness and features of the developed solution structure theorems are demonstrated via examining bioheat transport in skin tissue and during magnetic AG-881 hyperthermia. (C) 2011 American Institute of Physics. [doi:10.1063/1.3580330]“
“BACKGROUND: Neurologic complications (NCs) are the major adverse events after left ventricular assist device (LVAD) surgery. Pre-operative and post-operative factors associated with NCs in patients with LVADs were investigated.
METHODS: We reviewed 307 consecutive patients undergoing LVAD surgery (167 HeartMate I and 140 HeartMate II devices) at Columbia University Medical Center between November 2000 and December 2010. Clinical characteristics and hemodynamic and laboratory indexes were analyzed.
