The Relationship

In the borderland between psychiatry and neurology the clinician occasionally encounters patients with diseases which challenge diagnostic skills and treatment methods. A case is presented in which the coexistence of multiple sclerosis and schizophrenia raises essential questions about the relationship of mind and brain. A young woman with multiple sclerosis developed a clinical picture of schizophrenia in the initial stages of her disease. During sodium amobarbital interviews the patient's mental functioning cleared temporarily, although tranquilizers failed to control disruptive behavior. Electroconvulsive therapy was administered with dramatic improvement of her psychiatric disorder and no worsening of her neurological disease. In the seven years since recovery she has married and raised two healthy children without recurrence of either neurological or psychiatric disorder. While no cause-and-effect relationship can be defined, such cases emphasize the need for further studies of the relationship of central nervous system disease to psychiatric disorder.

The Relationship

The results of a study investigating the relationship of psychiatric and cognitive disorder with strabismus and its treatment in primary school aged children are reported. Results suggest that children with strabismus have a higher prevalence of psychiatric disorder, particularly an emotional disorder or psychosis. Subjects also had an increased risk of having educational problems and of exhibiting difficulties with tasks involving visual perception. Variables related to the nature and treatment of the strabismus did not appear influential in the development of the psychiatric disorder. Family disruption was significantly associated with both the presence of strabismus and emotional and behaviourial problems in the children reported by parents and teachers.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.
