Experimental evaluation of complete electrically powered ventricular assist system.

The LVAS utilizing an intrathoracic blood pump and a parathoracic, electrohydraulic energy converter has a number of promising features. These include: transcutaneous energy transmission and an implanted variable volume device which eliminate the need for percutaneous access; utilization of an intrathoracic blood pump and variable volume device which allow the diaphragm and abdominal cavity to remain intact; parathoracic or subcutaneous location of the transformer secondary, energy converter, internal battery and interconnecting elements allowing replacement with a minor surgical procedure; employment of the "biolized" continuous blood contacting surface which has the potential of long-term use without anticoagulants and utilization of an electrohydraulic energy converter which provides synchronization without requiring transducers and associated electronics and which provides lubrication of mechanical components. The development effort, which began separately in 1977 and has been conducted jointly by Nimbus and the Cleveland Clinic since 1980, has demonstrated that the above features can be incorporated in a reliable LVAS. In particular, the system in vivo test series have demonstrated the soundness of the basic concepts and led to refinements which were demonstrated in the 6-1/2 mo test. All elements of the system have been utilized during the in vivo test program. Component tests of significance include: LVAS and total heart blood pump in vivo experiments of up to 7 mos duration which demonstrate the blood compatibility of the biolized surface without the use of long-term anticoagulation.(ABSTRACT TRUNCATED AT 250 WORDS)

Classification of threatened premature labor related to treatment with a prostaglandin inhibitor: indomethacin.

68 patients complaining of premature uterine contractions were treated with a prostaglandin synthetase inhibitor--indomethacin. This agent had a marked effect on uterine contractions suppressing them completely after 1--8 h from the administration of the drug. Classificaiton of the premature contractions according to a scoring system method is analyzed in this study. The score classified the patients into three groups and enabled us to treat them with a correct dosage and period according to the clinical findings at admission of the patients. Indomethacin treatment was effective in all the 68 patients. The drug was well tolerated by all the patients with minimal side effects. The outcome of the newborns was satisfactory, and laboratory tests on various systems of the pregnant women and newborns were normal during and after treatment with indomethacin.

Prepregnancy genetic testing for age-related aneuploidies by polar body analysis.

Current practice for prevention of chromosomal aneuploidies involves prenatal screening and termination of pregnancy, a procedure that is not universally acceptable. We introduced prepregnancy genetic testing by sampling and fluorescence in situ hybridization (FISH) analysis of the first and second polar body (PB), to avoid fertilization and transfer of embryos resulting from aneuploid oocytes. In 395 in vitro fertilization (IVF) patients of advanced maternal age, the first and second PBs were removed following their extrusion from oocytes and studied by FISH, using probes specific for chromosomes 13, 18, and 21, to detect and avoid the transfer of oocytes with common aneuploidies. Overall, 3,651 oocytes obtained from 598 IVF cycles were available for FISH analysis, with 2,952 showing interpretable FISH results (80.9%). The analysis revealed 1,271 (43.1%) oocytes with aneuploidy, which were excluded from transfer and subjected to follow-up FISH analysis to confirm PB diagnosis in the cleavage or blastocyst stage embryos. Only embryos originating from 1,681 aneuploidy-free oocytes were transferred back to patients, resulting in 119 pregnancies overall, from which 78 healthy children have already been born, 35 were spontaneously aborted, and 16 are ongoing, after confirming PB diagnosis by prenatal diagnosis. The results demonstrate that PB-based preimplantation diagnosis may be used for prepregnancy screening in women with age-related risk for common aneuploidies.

Perforated gastric ulcer complicating corticosteroid therapy in acute rheumatic fever.

We report an 11-year-old boy with acute rheumatic fever who presented with gastric perforation while treated with corticosteroids (CS). He had been treated initially with acetylsalicylic acid for 11 days, CS replaced the treatment with acetylsalicylic acid due to deterioration of carditis. The possible pathogenesis is discussed.

The Highmark Pegasus Project report: characteristics of highly successful health plans.

The Highmark Blue Cross/Blue Shield Pegasus Project was created in the fall of 1996 to benchmark best practices at health plans around the United States through extensive interviews, literature searches, and other measures. Characteristics of highly successful health plans across a number of major categories are summarized in the final recommendations presented by this report.
