The high cost of commercial CT-compatible stereotactic frames has restricted the availability of CT-guided stereotaxy for many neurosurgical centres. However, many of these centres do possess the standard stereotactic frames for projection radiography, of which the old type Leksell frame is probably the most common. We have devised a simple and low-cost modification to an old Leksell frame to allow CT-guided stereotaxy. The nature of the modifications allow complete freedom of positioning of the frame relative to the CT scanner and coordinate transformations can be performed simply and effectively. The modified frame has been used successfully for some 18 months and the modification has now been performed at two centres in the North West Regional Health Authority. We hope this modification will allow many other centres to embark on CT-guided stereotaxy. 相似文献

Over five and a half months stool cultures were performed in 154 patients admitted with suspected bacillary dysentery to the Professorial Paediatric Unit of the Teaching Hospital, Galle. Thirty one patients had a positive stool culture; Shigella dysenteriae type 1 was isolated in 23 patients, and S flexneri in 8. In both groups the antibiotic sensitivity pattern was uniform, the only difference being S dysenteriae type 1 being resistant to nalidixic acid while S flexneri was sensitive. This antibiotic sensitivity pattern was different to that reported from Colombo during the same period. Complications were observed in some patients with S flexneri infection. 相似文献

Calcitonin gene-related peptide (CGRP) and substance P (SP) immunoreactivity were investigated in the superior cervical ganglion of normotensive and genetically hypertensive Otago Wistar rats by an immunoperoxidase method. CGRP- and SP-positive varicose axons invested separate subpopulations of ganglion cells, neither of which contained neuropeptide Y. The densities of CGRP axons were similar in normotensive and hypertensive rats while the numbers of SP axons were several times higher in the hypertensive strain. Decentralization of the ganglion or chronic capsaicin treatment removed all immunoreactive terminals, indicating that both axon populations are likely to be collaterals from thoracic sensory afferents. 相似文献

Ethylcellulose inserts of niridazole fabricated by casting were studied for in vitro release and in vivo clinical effectiveness. The in vitro drug release was steady and sustained for over 7 days and followed diffusion kinetics. Selected batch, EN3, was evaluated clinically in patients with periodontitis for 6 months. A significant improvement (α ≤ 0.05) in clinical indices from baseline was observed. Intergroup study revealed a significant (α ≤ 0.01) change in the bleeding index, gingival index, plaque index, calculus criteria, and pocket depth. Significant reduction in total bacterial count in gingival crevicular fluid was observed before and postdevice insertion, as well as between control and treatment groups. 相似文献

OBJECTIVES: To compare the use of preventive practices of Hispanic- and African-American women aged 50 and older. DESIGN: A cross-sectional survey. SETTING: Inpatient and outpatient units of a teaching hospital located in South Central Los Angeles. PARTICIPANTS: Convenience sample of 337 women aged 50 and older. MEASUREMENTS: Demographic and lifestyle characteristics and selected preventive practices. Preventive practices reported were self-breast examination, mammography, Papanicolaou (Pap) smear, digital rectal examination and stool occult blood examination, sigmoidoscopy, chemoprophylaxis, and immunization. Information was obtained in a face-to-face interview. RESULTS: African-American women were more likely to have had a Pap smear ever and to have used aspirin prophylaxis than Hispanic women. CONCLUSION: There were no major differences in the use of preventive services by the two ethnic groups except for Pap smear and aspirin use. Immunization and colorectal cancer screening rates were low in African-American and Hispanic women. 相似文献

We report a case of Wilms tumour associated with unilateral partial aniridia. Although Wilms tumour is known to be associated with bilateral aniridia, there is only one previously reported case associated with dysplasia of the iris. 相似文献

An epileptic patient on sodium valproate therapy, who developed acute liver failure following acute hepatitis A infection is reported. The hepatotoxic effects of this drug, and the possibility of intercurrent infection precipitating the toxic effects are discussed. 相似文献
