Repair of any defect in the eyelid depends on its size and position and the state of the surrounding tissues. Basal cell carcinoma (BCC) is the most common malignant tumour of the eyelids, and squamous cell carcinoma (SCC), mixed carcinomas or basosquamous cell carcinomas (BSC), and cutaneous melanomas (CM), also invade the eyelids and periocular zones. Reconstruction of the eyelids and associated orbital structures after resection requires a complete understanding of the anatomy. The adequacy of the reconstruction is judged by the quality of functional restoration and the aesthetic appearance. The purpose of this study was to document various, simple or complex reconstructive procedures that may be used after excision of malignant tumours of the eyelids and to assess the outcome of surgical treatment. 相似文献

From 1986 to 2001, 17 patients (aged 26–77 years) were treated using the vertical trapezius musculocutaneous flap. A two-stage procedure was used in 7 and a single-stage island flap in 10. The donor site was closed directly in all patients. Mean length of hospital stay was 16 days (range 12–25). There was no operative mortality. Complications were one partial flap necrosis and two seromas of the donor site, complicated by infection. With a minimum follow-up of more than two years, our study confirms the usefulness of the vertical trapezius musculocutaneous flap in head and neck reconstructive surgery. It is a reliable, thin flap of uniform thickness, which carries hairless skin. The length and thickness of its pedicle allows excellent mobility. The main disadvantage of the flap is the complete sacrifice of the muscle necessary for total mobilisation of the flap, and the intraoperative repositioning of the patient. 相似文献

The association of leptin with body fat concentration is well established. There is also experimental evidence of a direct effect of leptin on lipid metabolism. The aim of this study was to evaluate whether leptin levels are related to the corresponding serum lipid levels independently of body fat mass. The study population consisted of 294 phenotypically healthy school children aged 6 to 12 years. Age, sex, body weight, height, Tanner stage, and triceps skinfold thickness were recorded for all participating subjects. A blood sample was drawn in the morning after a 12-hour fast, and serum total, high-density lipoprotein (HDL), and low-density lipoprotein cholesterol; triglyceride; and leptin levels were determined. Multiple regression analysis showed that triglyceride values were positively correlated with the ln(log(e))-transformed leptin levels (beta =.01, P <.001), whereas HDL levels were inversely associated with lnleptin values (beta = -.06, P =.05) after controlling for age, sex, Tanner stage, and body mass index when each of the lipid parameters was tested separately in the regression model. However, the introduction of both triglycerides and HDL values in the same model eliminated the significance of association of HDL with lnleptin, and the positive relationship of triglycerides with lnleptin remained significant. Our results indicate that triglycerides are independently associated with leptin levels after controlling for any known confounder. 相似文献

The post-injury responses of retinal ganglion cells elicit a number of glial reactions which have not been completely understood. The bilateral pattern of non-neuronal retinal cell proliferation was examined in association with the differential fates of unilaterally injured adult retinal ganglion cells by means of bromodeoxyuridine (BrdU) immunocytochemistry. Lateralization of the glioproliferative events was studied by analysing both the experimental and the uninjured contralateral as well as matched retinas of sham-operated animals. Control adult rat retina included very few BrdU-positive cells within the nerve fibre and ganglion cell layers; however, experimental retinas of degenerating groups exhibited statistically significantly higher densities of newborn cells in most layers. Clusters of labelled cells were found in the inner plexiform layer related to OX-42 staining, indicating their microglial nature. Indeed, double-labelling experiments, after short-term unilateral optic nerve crushing, identified proliferating retinal glial cells in vivo. Both types of glia, astroglial and microglial cells, exhibited BrdU-positive labelling in injured as well as uninjured experimental rat retinas. Moreover, microglial proliferating cells were also identified in explanted retinal pieces after 2 days in culture. Affected and contralateral retinas responded similarly to the unilateral experimental manipulations applied with respect to BrdU labelling. The acute glial responses observed suggest that bilateral glial proliferation might represent a common response related to degeneration events in both retinas, i.e. ipsi- and contralateral to the experimental injury. 相似文献

There is increasing interest in the therapeutic potential of cannabis-based medicinal extracts in multiple sclerosis. Cognitive deficits that have been attributed to long-term heavy recreational use of cannabis are not necessarily extended to controlled pharmaceutical use of cannabis-based medicinal extracts. Available data indicate that after relatively short-term administration of cannabis-based medicinal extracts no significant cognitive decline occurs. Due to the absence of large scale long-term systematic clinical trials of cannabis-based medicinal extracts in multiple sclerosis therapeutics, however, many issues remain unresolved, including the possible adverse effects of cannabis-based medicinal extracts on cognition. This article critically reviews the current literature and considers the potential for cognitive adverse effects of long-term cannabinoid use in multiple sclerosis therapeutics. 相似文献
