Pro: intraoperative transesophageal echocardiography is a cost-effective strategy for cardiac surgical procedures

TEE is an expensive but useful intraoperative diagnostic strategy for cardiac surgical procedures. It can alter surgical management with tremendous potential benefits to the patient. It also has the potential to avoid unnecessary surgery and reduce the risk of complications such as reoperation, thromboembolism, and stroke. As with any new technology, the indications for its use must be evaluated on the basis of cost, benefits, and efficacy to determine the true value and cost-effectiveness in a particular application. Based on the information presented in this report, it can be concluded that TEE is a cost-effective strategy for valvular and congenital heart repairs. Current data are very convincing that TEE has the potential to be cost-effective in reducing the risk of stroke in selected populations of cardiac surgical patients. As experience with the use of TEE in its various applications increases and the technology itself continues to improve, it will undoubtedly become a more valuable and cost-effective strategy for cardiac surgery.     

Anticonvulsant and antibiotic prophylaxis in head injury

The evidence for and against the prophylactic use of anticonvulsants and antibiotics in head injury is reviewed. There is a lack of blinded placebo-controlled trials in this area. On balance there is no compelling evidence to support the use of either anticonvulsant or antibiotic prophylaxis in head injury, with the possible exception of antibiotic prophylaxis in compound depressed skull fractures and penetrating brain injuries.     

Resistance transfer fecal coliforms isolated from the whippany river

Three sites on the Whippany River, a tributary of the Passaic Watershed in Morris County, N.J., were monitored for resistance transfer coliforms. A high percentage of fecal coliform isolates showed multiple antibiotic resistance. A significant number of lac⁻ and lac⁻ isolates proved to be donors of transmissible antibiotic resistance plasmids (R donors), by conjugation with a recipient strain of Salmonella gallinarum. Re-examination of testing methods used for recreational and potable water sources is suggested by these findings.     

Surgical management of locally recurrent rectal cancer

The surgical management of locally recurrent rectal cancer may involve major procedures and is not for the faint-hearted. Nevertheless, such treatment is preferable to chemotherapy and radiotherapy; the latter will fail over a period of months during which the patient is likely to experience intractable pain. Radical surgery offers good palliation and a better quality of life. Survival is prolonged by such operations which may be curative in up to one-third of patients. Nevertheless, surgeons must be realistic in their assessment of and discussions with patients.
