眼窝再造联合义眼座置入术 总被引:1,自引:0,他引:1
目的评价烧伤后用全厚皮片行眼窝再造术联合羟基磷灰石义眼座置入的疗效。方法对10例由于铁水、强酸、强碱及火药烧伤引起的眼窝闭锁进行手术治疗。其中已摘除眼球者6例,有残留萎缩眼球者4例。对8例眼部烧伤患者行一期羟基磷灰石义眼座置入同时行全厚皮片移植眼窝再造术,2例为义眼座置入后二期行眼窝再造术。皮片取自上臂或大腿内侧,包裹自制眼模在置人羟基磷灰石义眼座后置入眼窝内,上下眼睑行睑缝合术,术后6~10个月剪开睑缘,定制义眼片。结果经8~36个月(平均23.2个月)的随访,皮片均成活,义眼座无暴露,无继发感染,患眼上下穹窿形成好,放置义眼片后外观满意,无义眼片自行脱出现象。结论对一些已无结膜组织的严重烧伤患者,用全厚皮片行眼窝再造术是较为有效的手术方法。 相似文献

Bladder cancer is one of the malignancies encountered frequently in urological practice. Since the three main treatment modalities
(surgery, chemotherapy and radiotherapy) may be used alone or together, there are many treatment options. In this paper the
current approaches in the treatment of bladder tumours are reviewed and the policy in Marmara University Hospital is described. 相似文献

Abdominal Stab Wounds in Children: an 18-Year Experience 总被引:1,自引:0,他引:1
Hayrettin ?ztürk Abdurrahman Onen Selcuk Ot?u Ali hsan Dokucu Yusuf Yamur Senol Gedik 《European Journal of Trauma》2002,28(2):85-89
Objective: Evaluation of the diagnosis, management, and the role of selective treatment in children with abdominal stab wounds.
Patients and Methods: 59 children (56 male and three female) were included in the study. The patients' median age was 11.8 years (range, 5–14 years).
Time between injury and admission was about 3 h. Laparotomy was performed in 44 patients (74%). Solid organ injury was detected
in 32 of these patients (73%) and could not be observed in twelve (27%). 15 patients (26%) were treated conservatively, and
only one (6.6%) underwent laparotomy during the follow-up. The stomach was the most frequently injured organ (ten patients),
followed by the intestines (nine patients). Types of surgical treatment were as follows: primary suture in 28 patients, resection-anastomosis
in three, and osteotomy in two.
Results: Some prognostic factors such as presence of abdominal organ evisceration and pneumoperitoneum were not significantly correlated
with intraabdominal organ injury, whereas some other risk factors such as acute abdomen on admission (p < 0.002) or abdominal
clinical and hemodynamic findings (p < 0.001) showed significant correlation with intraabdominal organ injury. The relative
risk (odds ratio) of developing an intraabdominal organ injury was > 2 for patients with signs of an acute abdomen on admission.
Postoperative complications were observed in five patients with organ injuries. None of our patients died.
Conclusions: Conservative treatment can be safely performed in most children with abdominal stab injuries. Signs of major internal hemorrhage
or generalized peritonitis are an absolute indication for emergency operation for abdominal stab wounds. Peritoneal penetrations,
free air on the abdominal X-ray, and omental or intestinal evisceration are poor indicators of significant organ injuries,
and patients presenting these signs shold be closely followed up for developing acute abdominal symptoms.

Summary In this study intra-arterial Endothelin-1 was applied to rabbit basilar arteries and morphological findings were compared between two groups who were either perfusion fixed or immersion fixed. We planned to establish the quantitative dimension of the drug-induced morphological alterations, independent of the fixation technique's effect.There was an abundance of collagenous fibres deposited among the smooth muscle cells which was not observed in control arteries and after immersion fixation. These degenerative changes are similar to the finding following subarachnoid haemorrhage. The only fixation-related difference was the fact that lamina elastica interna was not corrugated in the perfusion fixation group.It is concluded that, the observed changes in the connective tissue of the arterial wall alter the passive elastic properties and so affect the degree of the response to the vasoactive messengers. 相似文献

Summary Modification of a type of end-to-side anastomosis that has been described before is studied. The recipient artery is occluded for only 3–4 minutes to complete the anastomosis by using only the running suture. The anastomotic site was studied by inspection and Scanning Electron Microscope (SEM) at different times after the operation on 30 rats. 相似文献

The authors describe a case of giant fusiform aneurysm of the basilar artery presenting with ischemic symptoms. Angiography and CT revealed vertebro-basilar fusiform aneurysmal dilatation. Fusiform vertebro-basilar ancurysm is associated with various complications particularly brain stem infarction. Similar lesions in the literature are reviewed and the relationship between this clinical entity and cerebral ischemia, particularly brainstem infarction are discussed. 相似文献

An attempt was made in two experiments to reinvestigate the effects of the antiandrogen cyproterone acetate (CA) on mouse social behavior in a variety of ethologically-assessed paired encounters. The data confirm that CA reduces offense (threat and attack) in animals when both subjects receive the material but that CA has no such action in other pairings. This suggests that CA's major suppressive effect on "hostility" is expressed in mice via a reduction in "attack-promoting" pheromone production. Indeed, there was evidence in the more chronic study that CA, could augment (via a central mechanism?) offense in subjects paired with docile anosmic opponents. Changes in defense were largely responses to variations in the degree of attack to which animals were subjected. The antihormone also had actions on other aspects of behavior including sexual activity, social investigation and immobility in such tests. CA had a potent suppressive action on the weights of sex accessory glands. The data do not suggest that CA can be used as a specific antihostility agent. 相似文献

The reinvestigation of the aerial parts of ARTEMISIA SANTONICUM afforded, in addition to three known eudesmanolides, six new ones, all closely related to taurin. The structures were elucidated by high-field NMR spectroscopy. 相似文献
