SETTING Süreyyapaşa Centre for Chest Diseases and Thoracic Surgery, Istanbul, Turkey. OBJECTIVE To report the frequency of treatment side effects in cases of multidrug-resistant (MDR-TB) tuberculosis. DESIGN A retrospective review of the medical records of 263 patients who received individualised treatment for MDR-TB between April 1992 and June 2004. … (More)
Childhood minimal change nephrotic syndrome (MCNS) has often been associated with allergic symptoms such as urticaria, bronchial asthma, atopic dermatitis, allergic rhinitis and elevated IgE levels and referred to involve immune dysfunction. Fc epsilon RII is known to be involved in IgE production and response. Interleukin-4 is being recognized as a major… (More)
A fiber-optic ultrasound sensor is presented. The sensor consists of a continuous length of single-mode optical fiber with a built-in Fabry-Perot interferometer. The acoustic pressure produces changes in the index of refraction along the interferometer cavity through the strain-optic effect, thus modulating the reflected power of the light propagating in… (More)
Two designs incorporating embedded fiber Fabry-Perot interferometers as strain gauges were used for monitoring gas pressure in internal combustion engines. Measurements on a Diesel engine, a gasoline-fueled engine, and a natural-gas engine are reported.
A reflectively monitored Fabry-Perot temperature sensor is characterized over a 1250 degrees C temperature range. Dielectric mirrors for the interferometer are incorporated into a continuous length of single-mode fiber by a fusionsplicing technique. The change in optical phase per unit temperature is nearly constant above room temperature but decreases at… (More)
PURPOSE Family caregivers of cancer patients become responsible for many elements of cancer care, usually without preparation or training in provision of care. Their efforts of care generate caregiving burden, which could deteriorate caregivers' quality of life (QOL). METHOD A secondary data analysis of a cross-sectional descriptive study was conducted to… (More)
Fiber-optic sensors were installed on fatigue-critical components in the superstructure of a railroad bridge to monitor dynamic strains induced by trains crossing the bridge as well as to detect the onset of cracks. Each fiber Fabry-Perot interferometer (FFPI) strain gage was adhesively bonded to a stainless-steel strip to facilitate all-weather… (More)
PURPOSE The role of family caregivers in cancer care continues to expand, and it has been suggested that the caregiving influences health-promoting behaviors. The purpose was to describe the caregiving burden and health-promoting behaviors of the family caregivers of cancer patients and to determine the relationship between caregiving burden and… (More)
A temperature-sensor system based on low-coherence interferometry with a fiber Mach-Zehnder interferometer as a phase modulator was implemented. A measurement range of 20 to 800 degrees C with a resolution of 0.025 degrees C (corresponding to 0.0004 fringe) was achieved with a 1-mm-long fiber Fabry-Perot interferometer as the sensing element.
