Thyroid Function and Autoimmunity Versus Number of Pregnancies.

Background: Thyroid autoimmunity may be linked to infertility, in both thyrotropin (TSH)-dependent and TSH-independent fashion. The aim of the present study was to assess this presumed reciprocal relationship of thyroid autoimmunity and pregnancy.

Methods: TSH and antithyroid peroxidase autoantibodies (anti-TPO) were evaluated retrospectively over an eight-year period in 444 Greek women who had previously none or at least one pregnancy (>28 weeks).

A new technique to increase coronary flow. Preliminary report.

This study was planned to investigate whether part of the energy produced by cardiac contraction to propel blood toward the systemic circulation can be used to increase the coronary flow in systole. Ten devices (I-X) designed to divert laterally part of a flow column (without substantially increasing resistance to flow) were tested in a mock circulation and in nine anesthetized dogs. An increase of 11.

Electrocardiographic abnormalities in hypothyroidism before and after exercise.

Eleven men and 50 women with severe hypothyroidism were studied. All patients had a serum PBI less than 3.0 mug/100 ml, 131I 24 hours uptake less than 13% and a a photomotogram contraction and half relaxation time of 380 msec or more.
