Summary Although careful measurement of the size of capillary loops is mandatory in the evaluation of diabetic microangiopathy, no
current technique allows rapid and careful morphometric analysis of capillaroscopic findings. In an attempt to solve this
problem, assembling readily available instruments, the authors have set up an original apparatus for computed videomicroscopy.
The apparatus ensures detailed morphological assessment of single loops at high magnification. Each single frame stored on
videocassettes can be digitalized for morphometric analysis, saved on floppy disk or printed by means of a graphic printer. 相似文献

Tumefactive demyelination is an aggressive, localized, generally solitary area of demyelination that often mimics a neoplasm. We present a case of a 13-year-old female patient who presented with sudden-onset progressive hemiplegia and hemianopsia. Magnetic resonance imaging of the brain showed tumefactive demyelination with partial rim of enhancement. During inpatient rehabilitation, she developed myalgias, rash, and abdominal and mouth pain with evidence for severe neutropenia. The neutropenia was determined to be a secondary complication of the tumefactive disease process. This scenario may be concerning in an inpatient rehabilitation setting, as patients share common areas, increasing the risk of acquired infection while neutropenic.

The purpose of this pilot study was to implement care collaboration measures into a critical care advanced practice. The intervention included an outreach algorithm and a standardized handoff tool during care transition. One hundred eight patients were enrolled; 5 (4%) experienced unplanned readmission. There was no significant association with transition time and the ability to complete the algorithm. Comorbidities of chronic obstructive pulmonary disease (P < .005), a PaO2 ratio < 200 (P < .003), and pulmonary disease (P < .027) showed increased unplanned readmission within 48 hours of transition. Implementing critical care collaborating measures was not affected by transition time and unit care flow. 相似文献
