Sonohysterography: the next step in the evaluation of the abnormal endometrium.

Sonohysterography is a simple ultrasound (US) procedure that may be used to evaluate the endometrium. The technique involves placement of a 5-F catheter into the endometrial canal with subsequent instillation of sterile saline solution under US guidance. Fifty patients successfully underwent sonohysterography because of apparent abnormal endometrial thickening at transvaginal US, a nonspecific finding. Patients tolerated this procedure well, and no complications were encountered. In the 39 patients who proved to have endometrial pathologic conditions, sonohysterography demonstrated focal processes (polyps, carcinoma, hamartoma) in 15, diffuse processes (hyperplasia, secretory endometrium) in 21, and both focal and diffuse pathologic conditions in three. If a focal process can be delineated, a visually directed biopsy may be necessary. However, if the process is diffuse, a blind aspiration biopsy may be performed on an outpatient basis. In the majority of patients, the diffuse or focal nature of the disease could not be predicted on the basis of initial transvaginal US. Because sonohysterography allows distinction between diffuse and focal abnormalities, it provides physicians with a cost-effective way to plan the next step in case management.

Studies of human IgM anti-IgG cryoglobulins: II. Isoelectric focusing characteristics of the reactive antigen and residual serum IgG pools.

The co-isoelectric focusing characteristics of the antigen-IgG and residual IgG pools in the serum of patients with mixed IgM:IgG cryoglobulinemia have been determined. The antigen IgG purified from five IgM cryoglobulins and the residual IgG purified from serum depleted of cryoglobulin were radiolabelled and co-isoelectric focused in polyacrylamide gels in order to determine if the IgM anti-globulin reacted in order to determine if the IgM anti-globulin reacted with IgGs having unique physicochemical properties. Electrofocusing profiles of the IgG from four sera showed only minor differences when the antigen-IgG was compared to residual serum IgG. In one instance, the IEF profile of the antigen-IgG pool was markedly restricted and of a different charge dispersion than the residual serum IgG. This correlated with the limited antigenic specificity previously shown for the autologous IgM antiglobulin.

MR imaging of blue rubber bleb nevus syndrome.

This report describes the use of magnetic resonance imaging in the evaluation of a patient with blue rubber bleb nevus syndrome, a rare entity consisting of multiple cutaneous and visceral hemangiomas. The bright signal obtained on T2-weighted images is probably the result of slow flow or thrombosis, typically present in these lesions, and allows for easy recognition.
