Transmission of BCG-associated tumor resistance from maternal to newborn guinea pigs.

Resistance to line-10 hepatocarcinoma was studied in the newborn offspring of inbred strain-2 Sewall Wright guinea pigs that had recovered from this tumor after prior administration of subcellular components of Mycobacterium bovis strain BCG. These mothers gave birth to 15 offspring, 53% of which resisted repeated challenges with this tumor. Offspring of mothers who had been given only BCG components were similarly tested. Complete protection was observed in 23.5% of 17 babies and attenuation of disease in many others. All control offspring from normal, untreated mothers succumbed to this tumor. Resistance was associated with delayed cutaneous hypersensitivity reactions to tumor and mycobacterial antigens.     

Inpatient admissions for interventional radiology: philosophy of patient management

As an alternative to performing interventional radiology on inpatients under the care of internists and surgeons, the authors have established a cardiovascular radiology admitting service for well-screened, elective patients. The patients are admitted under the care of a cardiovascular radiology fellow and a staff physician. From April 1982 to December 1983, 133 patients were admitted to the service. Patients are cared for in a surgical ward or in an intermediate unit, as determined by the clinical situation. Advantages of this approach include a broader patient referral base, improved rapport with clinical colleagues and patients, improved follow-up data, and rapid evaluation and treatment, resulting in short hospital stays. The major disadvantages involve the commitment of time and staff necessary to provide quality care. The concept of the interventional radiologist in the role of admitting physician has important implications in terms of negotiations for additional financial compensation, commensurate with the skill and time required for performing these procedures and caring for the patient.
