Abstract: Stellate ganglion block is commonly used to treat the sympathetically maintained pain which may occur in one‐third of patients with complex regional pain syndrome type 1. A complication that followed a single block and presented a diagnostic dilemma for the ophthalmologist is reported. 相似文献

Re-epithelialization of cutaneous wounds is a coordinated process of proliferation and migration of keratinocytes at the wound
edge. The study objective was to identify the differences in epidermal morphology, keratinocyte proliferation and matrix molecules
(laminin 1, laminin 5, type IV collagen) and their specific integrin (α3, α6) expression in biopsies of meshed split thickness
grafted and chronic wounds. The mean mitotic index of keratinocytes (ratio of cell cycle associated antigen Ki-67 expressing
keratinocytes to basal keratinocytes) was highest in chronic wounds (38.7%) compared to acute wounds (22.25%, range 5.7% to
54%). The mean thickness of the hyper-proliferative epithelium at the wound edge of chronic wounds was 0.69 mm compared to
0.15 mm at the wound margin of split thickness grafted wounds. Both chronic wounds and skin grafted wounds exhibited strong
laminin 5 immunoreactivity at the basal side of the epithelium, which extended under the most forward keratinocytes. Laminin
1 and type IV collagen immunoreactivity did not extend to the wound margin in either skin grafted or chronic wounds. In both
transplanted skin and chronic wounds, the integrin sub-units α3 and α6 exhibited a strong pericellular immunoreactivity on
the leading keratinocytes of the wound margin. Our data demonstrates that the proliferation of keratinocytes and the expression
of associated integrins are not impaired in chronic wounds.

Laparoscopic repair/peritoneal toilet of perforated duodenal ulcer 总被引:13,自引:6,他引:7
Summary Laparoscopic techniques have been refined to the point where exposure, haemostasis and tissue approximation by suture approach those obtained at open access surgery. We report a patient with acute perforation of an ulcer in the first part of the duodenum who was successfully treated by laparoscopic oversewing and omental patching. The clinical indications for contemplating use of laparoscopic surgery for acute ulcer perforation, techniques employed and the areas for potential improvement of instruments, needles and sutures are discussed. 相似文献

High-Temperature Short-Time Heat Inactivation of HIV and Other Viruses in Human Blood Plasma 总被引:4,自引:0,他引:4

An ultra-short-time heating system was used to process blood plasma spiked with various viruses (HIV, vesicular stomatitis virus, encephalomyocarditis virus). Virus reduction and recovery of plasma proteins were measured at various temperatures from 65 to 85 degrees C. Processing at 77 degrees C and 0.006 s resulted in a high level of virus kill, including greater than or equal to 4.4 log10 HIV, while maintaining protein structure and activity essentially intact. 相似文献
