We encountered two cases of maternal coccidioidomycosis with placental involvement. Altered cell-mediated immunity during pregnancy makes the diagnosis of desseminated coccidioidomycosis difficult by the routine serologic tests; placental examination provides specific information. A high index of suspicion regarding this disease and prompt institution of appropriate therapy are necessary in order to decrease maternal and neonatal mortality.
The demonstration of fetal diseases and anomalies in utero can now be performed with a high degree of accuracy with modern ultrasonic equipment. This paper describes the more common and important fetal anomalies which can be demonstrated by ultrasound and indicates the importance of meticulous attention to technique and the significance of the acquistion of skill in real-time sonography by the physician-sonologist. The thoroughness of all obstetric sonographic examinations is emphasized to enable detection of unsuspected fetal anomalies. Specific methods to demonstrate these anomalies in the high-risk patient are also described. Several pitfalls in the diagnosis of fetal disease in utero are included which show the nonspecificity of some of the ultrasonic signs.

Biopsy of the sural nerve was performed on three patients with severe Minamata disease of more than 10 years duration. There were so many unmyelinated and poorly myelinated nerve fibers that myelinated fibers scattered irregularly in small numbers or in groups of peculiar features in the intraneural bundle. Abnormaly thin or poorly formed myelin sheaths were noticed. Incomplete myelination and abnormal myelination varied in size and shape appeared as fetal anomaly. Regenerated axons extremely small in size remained singly or in groups following regenerative sprouting. Sometimes, extremely small axons with normal myelination were noticeable, while the axons were lost, leaving myelin sheaths. Axons occasionally contained increased neurofilaments. Schwann cells were not so increased as in adult Minamata disease. Degenerative changes of nerve fibers still proceeded, presumably because the patients lived in the mercury-contaminated district. Myelin degenerations and glycogen deposits in the axoplasm were identified.

Intracardiac flow patterns were chronically altered by partially obstructing left ventricular (LV) inflow or outflow in midgestational fetal lambs. Physiological measurements of the fetal circulation were made serially through indwelling catheters and the use of radioactive microspheres. With LV inflow obstruction, mean LV output (LVO) decreased to 30% of control (P less than 0.01). Within seven days, the LV/right ventricular (RV) weight ratio decreased to 70% of control (P less than 0.01), and the mean LV/RV chamber volume decreased to less than one-half of control (P less than 0.001), simulating an early form of the hypoplastic left heart syndrome. With LV outflow obstruction, mean LVO decreased to 64% of control (P less than 0.05). Mean LV/RV wall thickness doubled (P less than 0.0001) and mean LF/RV chamber volume decreased to less than one-half of control (P less than 0.0001). Within four to ten days after increasing LV afterload, a large increase in LV mass occurred, which was demonstrated by morphometric analysis to be due to hyperplasia of ventricular myocytes. LV chamber volume decreased somewhat, simulating moderately severe congenital aortic stenosis. Over the long term (30--36 days), the mean LV/RV weight ratio decreased and the LV chamber was nearly obliterated, simulating very severe congenital aortic stenosis. The results suggest that by varying preload and afterload in both ventricles of the fetus, various forms of congenital heart disease may be simulated.
An immunoradiometric assay (IRMA) has been developed based on the inhibitor which arose in a polytransfused severe haemophiliac. The two-site IRMA measures antigens closely associated with the procoagulant parts of the factor VIII complex, which are termed FVIIC antigens or FVIIICAG. FVIIICAG was present in normal plasma and also, at a slightly lower concentration, in normal serum. In 37 patients with haemophilia A, 36 had FVIIICAG levels of less than 10% of the normal plasma pool. In patients with von Willebrand's disease the levels of FVIIIC and FVIIICAG were in good agreement, both before and after treatment with cryoprecipitate or DDAVP. FVIIICAG was relatively stable in plasma at 37 degrees C and could also be detected in cord and fetal serum. The assay is of potential value for detecting reduced levels of factor VIII, for carrier detection and for the prenatal diagnosis of haemophilia.

A case of maternal Listeria monocytogenes septicemia at 19 week's gestation is presented. Successful treatment of the mother with ampicillin resulted in remission of maternal symptoms and subsequent term delivery of an unaffected infant, indicating fetal disease is not an inevitable consequence of maternal Listeria sepsis.
Endometrial cells from the uteri of pregnant and nonpregnant cattle were cultured. The presence of one or both of two viruses, noncytopathic mucosal disease virus and bovine syncytial virus, was demonstrated in seven of 19 endometria investigated. It was necessary to subculture the cells an average of four times to detect the viral infections. Difficulties were encountered in producing endometrial cell cultures from cows at term or near the end of term and also from older animals. The infections detected may be significant because both of the viruses isolated are capable of infecting the bovine fetus in utero and mucosal disease virus has been associated with bovine fetal diseases.
