[Calcium-containing incrustations on IUD's--detection using electron scanning microscopy]. 1984

K Patai

On the surfaces of intrauterine contraceptive devices the occurrence of incrustations has been noticed, which presented blade or needle crystal structure on electron microscopic scanning exposures. In conformity with earlier findings, these products showed the character of calcium compounds. Attention is called to the significant part that such an incrustation is likely to play in the rise of complications and harmful side effects.

D008796	Metrorrhagia	Abnormal uterine bleeding that is not related to MENSTRUATION, usually in females without regular MENSTRUAL CYCLE. The irregular and unpredictable bleeding usually comes from a dysfunctional ENDOMETRIUM.

D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
