[Religious delusion 13 years after brain injury].

We report here with a case of religious delusion in a 39 years old woman. She had suffered a head injury with right temporal concussion 13 years before but had no earlier history of psychiatric disorder. In view of the fact that this acute psychiatric state lasted for a short duration of time and that personality and affects were preserved, this incident is compared to the schizophreniform disorder of the type DSM-III-R. The hypothesis of an acquired predisposition due to head injury has been put forward as an explanation.

[Systematized temporal delusion and hearing disorders of cortical origin].

We report a case of delusion characterized by a time disorientation with a constant three days advance. Five years previously, the patient had suffered a left hemisphere stroke with aphasia. The delusional belief appeared at the same time as a cortical deafness following a second right hemisphere infarction. There was severe behaviour disturbances which lasted seven months, then cleared without any other change in the clinical picture. The lesions involved the left parietal lobe as well as the temporal and insular regions of both hemispheres.

Polyanhydride microsphere formulation by solvent extraction.

A novel process based on solvent extraction was developed to produce drug-loaded polyanhydride microspheres for controlled-release applications. The technique consists of adding a chloroform solution of polyanhydride and drug into a stirred silicone oil phase containing suspended droplets of surfactant. No chemical reaction, heating, nor contact with water was required in this process. The microspheres produced were capable of releasing various dyes for prolonged periods of time.

Osmotic water transport through cellulose acetate membranes produced from a latex system.

The advisability of a progressive curtailment of organic solvent film coating offers an incentive to develop latex systems. Here, the use of aqueous colloidal dispersions of cellulose acetate, plasticized with water-soluble additives, is proposed as an alternative way to obtain cellulose acetate membranes either by casting or spraying. The osmotic water permeability of both kinds of films was measured, as well as their loss of leachable materials and degree of swelling in a saturated solution of potassium chloride. The permeabilities varied over a wide range depending on the physicochemical properties of the plasticizer and its initial concentration in the latex, and on the conditions for coating (temperature, rate of spraying, and drying duration). High boiling point plasticizers gave more permeable films. Films prepared by casting were found to be sensitive to their sodium dodecyl sulfate content.

Mechanically strong films produced from cellulose acetate latexes.

Mechanically strong films, comparable with those obtained from organic solutions, can be produced from cellulose acetate latexes, a new type of dispersion, both by casting and spraying. The prerequisite conditions for high strength, which include choice of water-soluble plasticizers possessing some degree of volatility, are discussed.
