Simultaneous bilateral central catheters: a safe technique.

Optimal central catheter care includes restriction usage for blood sampling and blood product administration on enhance continued sterility, but our experience with 25 children receiving bone marrow transplants after cytoreduction challenges this concept. Prior to transplantation, bilateral percutaneous subclavian vein silastic catheters were inserted without incident, one utilized for continuous nutritional support in caloric quantity to assure body weight maintenance, and the contralateral catheter utilized for daily venous sampling plus administration of medications including blood products. Patients subsequently entered a protective environment and bi-weekly surveillance cultures were monitored. Nutritional therapy was given for 876 days through 53 catheters. One patient developed culture-proven sepsis, an organism first cultured from the skin. The patient complication rate of 4% and the per diem rate of 0.11% in this immunocompromised population compares favorably to the 10.5 and 0.32% incidence we previously reported for 200 children with unilateral catheters. These data demonstrate that bilateral central catheters can be safely utilized in children for nutrition and sampling.

Will the care be there? Vulnerable beneficiaries and Medicare reform.

The Medicare program is on the verge of major change. The proof of the value of reforms will not rest in how well the program meets the needs of the healthy and wealthy, but rather in whether they preserve or improve upon protections for those who would not be well served by an unregulated private sector--persons with low incomes and/or substantial health problems. This paper examines four key issues: Which beneficiaries will likely be best served by a system oriented around choice; what role traditional Medicare should continue to play and what changes will be needed; what protections are necessary for persons with low and moderate incomes; and how these reforms could be incorporated into broader changes to make Medicare more viable over time.

Sacral fractures in dogs: a review of 32 cases.

Sacral fractures have not been described well in dogs. The records of 32 dogs diagnosed with sacral fractures were evaluated for neurologic deficits at presentation and discharge. Follow-up was in the form of telephone survey or physical examination at recheck. A score was assigned for each dog at presentation, discharge, and follow-up (0 for normal, 1 for minor deficits, and 2 for major deficits). Fractures located lateral to the sacral foramina were called abaxial, and those medial to the sacral foramina were called axial. Axial fractures had significantly more severe deficits at presentation (p = 0.00017) and discharge (p = 0.03063), but not at follow-up. Neurologic status did not improve significantly during hospitalization in either fracture group, but had improved significantly at follow-up.

A moving target: financing Medicare for the future.

Since 1997, there has been a steady downward trend in projected Medicare spending as a share of the gross domestic product (GDP), substantially improving the long-run outlook for Medicare. But even with improvements in outlook, the required share of GDP will rise by more than 70%, and the question remains as to who will pay for Medicare in the future. This report examines a limited set of tax options and a flat beneficiary premium to illustrate the size of contributions necessary to achieve several different goals, and to explore the difference that multiple years of projections can make on these requirements.

Congenital extra-hepatic biliary cyst in a Congo African Grey Parrot (Psittacus erithacus erithacus).

An 8-week-old Congo African Grey Parrot (Psittacus erithacus erithacus) was presented with a history of abdominal enlargement since hatch. Trans-illumination of the abdomen suggested that the enlargement was due to marked hepatomegaly. This was supported by radiographic and ultrasonic examination. Postmortem examination revealed an extra-hepatic biliary cyst 4 cm in diameter.
