Recurrent tears following successful retinal detachment surgery.
In 17 cases of recurrent retinal tears occurring after successful retinal detachment surgery, the new tears developed on or near the treated primary tear in seven cases and away from the treated tear in ten cases. It took an average of 25.6 months for the second tears to develop, and almost all of the recurrent tears were the same distance from the limbus as the primary tear. The benefit of the 360 degree encircling band and the relationship of the thermal injury to production of a second tear is discussed.
Marfanoid hypermobility syndrome associated with Duane's retraction syndrome.
Marfanoid hypermobility syndrome together with Duane's retraction syndrome in two sisters is presented. To our knowledge, this is the first report of such a combination. A possible mode of inheritance is suggested.
Failure of metoclopramide to influence LH, FSH and TSH secretion or their responses to releasing hormones.
Intravenous metoclopramide (MET) (10 mg) induced a brisk PRL response with a mean +/- SEM peak of 85.3 +/- 7.7 ng/ml maximal at 30 min. L-Dopa, but not atropine pre-treatment, attenuated the prolactin (PRL) response to MET. This indicates that the antidopaminergic properties of MET mediate PRL secretion. MET did not influence basal levels of TSH, LH or FSH. Neither did it affect their response to the respective releasing of hormones. Our results indicate that dopaminergic blockade induced by iv MET, does not influence the secretion of the pituitary glycoprotein hormones.
Recurrent, isolated, post-febrile abducens nerve palsy.
A case presenting with three episodes of recurrent benign abducens palsy is reported. The patient experienced her first episode at age of 3 years, her second when she was 13 years old, and the last at the age of 25 during pregnancy. Full recovery was attained within approximately three months after each episode.
