OBJECTIVE: The purpose of this investigation is to determine the frequency of chromosomal or genetic causes of recurrent spontaneous abortion. METHODS : A cytogenetic study was made in of 921 couples for 13 years from January 1984 to December 1997 in which the woman was ascertained to have had two or more spontaneous abortions at our Cytogenetic Laboratory, Institute of Reproductive Medicine and Population, Seoul National University. RESULTS : The overall incidence of chromosome anomaly was 80 out of 921 (8.7%). There were 34 cases (3.69%) of reciprocal balanced translocation and 13 cases (1.41%) of Robertsonian translocation. Also 17 cases (1.85%) of inversion and 5 cases (0.54%) of X chromosome mosiacism was observed. In the case of reciprocal balanced translocation, chromosome 8,6,7,13 were preferentially involved over others. And in the case of Robertsonian translocation, chromosome 13 was preferentially involved. CONCLUSION: Our study demonstrates that cytogenetic analysis is indicated in couples with 2 or more spontaneous abortion and about half of these disorders are reciprocal balanced or Robertsonian translocations.

PURPOSE: To report a case of cancer-associated retinopathy developed in a patient with small cell lung cancer, which is a kind of paraneoplastic syndrome. METHODS: A 78-year-old woman presented complaining of decreased visual acuity and visual field that had developed about 15 days previously. She was diagnosed with small cell lung cancer 1.5 years ago and underwent 3 cycles of chemotherapy. At presentation, the best-corrected visual acuity was hand motion in both eyes and there was no afferent pupillary defect. Slit-lamp biomicroscopic examination revealed no specific abnormality in the anterior segment of either eye, and intraocular pressure was normal. Posterior segment examination demonstrated remarkable arteriolar narrowing in both eyes, but there was little doubt about the presence of an optic nerve lesion such as optic disc edema or pallor. RESULTS: Fluorescein angiography and brain magnetic resonance imaging (MRI) revealed no significant abnormalities. However, electroretinograms (ERG) demonstrated marked reduction in the a and b waves. Visual evoked response was delayed for the latency period. She was treated with systemic steroid, after which her visual acuity gradually improved.
