A case of anterior cruciate ligament disruption in a patient with an avulsion fracture of the lateral proximal tibia is presented. The "Segond" fracture is an unusual fracture that is important to recognize because it is often associated with anterior cruciate ligament disruption and anterolateral instability. These injuries are usually best treated by early surgical repair. 相似文献

Summary LL-D491941 is a new cytotoxic antibiotic selected for clinical phase I study because of its impressive pre-clinical anti-tumour activity and its low toxicity profile in experimental animals. A total of 15 patients were treated in centres in Glasgow and Amsterdam at doses ranging from 0.25 to 4 mg/m2. One minor response was noted in a patient with colonic carcinoma. The study was suspended following the discovery of unexpected cardiotoxicity. As this toxicity was not consistent with the standard (EORTC) European Organisation for Research and Treatment of Cancer toxicology profile, we chose to investigate the pharmacokinetics of LL-D491941 in mice and humans in more detail to try to explain this phenomenon. A major difference in plasma protein binding was discovered between mice and patients, with a suggestion of non-linear kinetics being noted at higher doses in humans. It is likely that these differences in drug handling account for the unexpected and serious toxicity encountered in this trial. 相似文献

One strategy for gene therapy in malignant disease is gene directed enzyme prodrug therapy (GDEPT). An exogenous enzyme gene is delivered to tumour cells. The enzyme, when expressed, can convert a non-toxic prodrug into a cytotoxic species that is capable of killing the cell in which it has been produced. The most frequently used systems are HSV thymidine kinase with ganciclovir and E. coli cytosine deaminase with 5-fluorocytosine. The bystander effect is of key importance to GDEPT: This describes the local spread of active species from cells that express the enzyme to kill adjacent, untransduced cells. The ultimate success of GDEPT will depend on the ability to achieve efficient gene delivery to and expression in target cells, whilst minimising expression in other tissues. A variety of techniques exist to achieve this goal, including loco-regional administration, manipulation of tumour blood supply and use of tumour-specific promoters to drive enzyme gene expression. 相似文献

St. Paul-Ramsey Medical Center in St. Paul, MN became one of the first hospitals in the United States to initiate a "stockless" par level inventory system. Successes with stockless led the hospital to look at implementing it in the OR to achieve a reduction of expense to revenue. Materiel Management and Surgical Services discussed a number of issues relevant to implementing a stockless program, including product flow, accuracy and cost of case carts and preference cards, item pricing, committed usage of items brought into the system and establishment of a steering committee. Specific OR issues and practices required evaluation and adjustment, such as the routine use of emergency direct ordering. Information systems support was brought in and a products committee established to do education and oversee the program. Savings for 1993-94 were $185,146. 相似文献

Two successful cases of eliminated atrial flutter and improved clinical status for Fontan patients are presented. An operation combining introduction of an extracardiac conduit for the Fontan connection, to direct all systemic venous blood away from the atrium, and atrial pathway division and cryoablation, is a useful surgical option for failing Fontan patients. 相似文献
