Diagnosis of fetal arrhythmias using echocardiographic and Doppler techniques

Fetal echocardiography is the most practical method for diagnosing prenatal arrhythmias. Because some prenatal tachyarrhythmias have been shown to respond to antiarrhythmic drugs, correctly diagnosing fetal arrhythmias has assumed new importance. With the aid of two-dimensional echocardiographic imaging, an M-mode cursor can be aligned to record atrial and ventricular wall motion--either independently or simultaneously. A consistent feature in the fetus is prominent atrial wall contractions that can be readily recorded on the M-mode tracing. By matching atrial and ventricular wall contractions with assumed P waves and QRS complexes, the fetal electrocardiogram can be reconstructed. In 57 fetuses studied, recurrent atrial and ventricular ectopic beats were the most common prenatal arrhythmias. However, atrial flutter, ventricular tachycardia, atrial and ventricular bigeminy and atrial and ventricular bradyarrhythmias have been correctly identified and in some instances appropriately treated. Marked fetal bradycardia in the midtrimester of pregnancy is shown for the first time to be caused by transducer pressure on the maternal abdominal wall.     

Pituitary growth hormone from human cadavers: neurologic disease in ten recipients

Creutzfeldt-Jakob disease (CJD) has been reported in three US patients previously treated with human growth hormone derived from large pools of human cadaver pituitary glands (pit-hGH). Neurologic disorders other than CJD occurred in 10 growth hormone-deficient patients treated with pit-hGH. These 10 cases could have been chance events or true syndromes; some cases may have been caused by transmissible agents contained in the pooled growth hormone product.

Treatment of leg ulcers with an allogeneic cultured-keratinocyte-collagen dressing

A living cellular allogeneic dressing made up of cultured keratinocytes adhering to a collagen film was used to treat 20 leg ulcers of various aetiologies in 16 patients. A reduction in pain was noted in 80% of cases, and promotion of granulation tissue in the ulcer bed in 70% of cases. In 10 patients, epithelialization of 71 +/- 29% of the ulcer was noted at Day 30.
