Psychosis associated with demonstrable brain disease.

Sixty-five psychotic patients with unequivocal evidence of brain pathology and a variety of neurological disorders were assessed with respect to phenomenology and outcome. No relationship was found between site of brain pathology and type of psychotic disorder. A majority of patients had a syndrome indistinguishable from schizophrenia without coarse brain involvement and shared similar variables predicting outcome of psychosis, thus raising important issues concerning their nosological status.

Pachyonychia congenita.

Pachyonychia congenita is a rare hereditary disorder characterized mainly by nail hypertrophy and dyskeratoses of skin and mucous membranes. A thorough literature survey since its first description in 1904 up to 1985 revealed 168 cases of pachyonychia congenita. There were no indications of any sex or ethnic group predilection. Based on this survey the following classification is suggested: type I (56.2% of cases), hyperkeratosis of nails, palmoplantar keratosis, follicular keratosis, and oral leukokeratosis; type II (24.9% of cases), clinical findings of type I plus bullae of palms and soles, palmar and plantar hyperhidrosis, natal or neonatal teeth, and steatocystoma multiplex; type III (11.7% of cases), clinical findings of types I and II plus angular cheilosis, corneal dyskeratosis, and cataracts; and type IV (7.2% of cases), clinical findings of types I, II, and III plus laryngeal lesions, hoarseness, mental retardation, hair anomalies, and alopecia.

Ganser symptoms, dissociation, and dysprosody.

Approximate answers (vorbeireden) are considered pathognomonic of the Ganser syndrome. Controversy has always surrounded the nosological status of this syndrome. Its recent inclusion in the DSM-III-R as a dissociative disorder is supported by this case report. The association of approximate answers, psychogenic amnesia, and dysprosody is reported here for the first time.

Isolation and characterisation of goat C-reactive protein.

A pentraxin was isolated from acute phase goat serum by its calcium-dependent affinity for agarose, and although it did not bind to phosphorylcholine immobilised on Sepharose, its binding to agarose was reversed by exposure to fluid phase phosphorylcholine. It was identified as goat C-reactive protein on the basis of its immunochemical cross-reactivity with human and bovine C-reactive protein. The molecule was composed of five identical, glycosylated, non-covalently associated subunits, each of molecular weight approx. 24,000. Acute phase serum levels in a small number of samples were not significantly different from normal levels (means 72 and 55 micrograms/ml, respectively), suggesting that goat C-reactive protein is not a major acute phase reactant. No other pentraxin was detected in goat serum.

Crystallization and preliminary crystallographic data for an antiprogesterone monoclonal antibody Fab' and steroid-Fab' complexes.

Crystals of an Fab' from an antiprogesterone monoclonal antibody (IgG1) have been grown from 1.5 M-ammonium sulfate, pH 5.5 to 8.5. The single crystals are hexagonal rods, space group P6222 (or P6422), with cell dimensions a = b = 135.2 A, and c = 124.2 A. Cocrystals of the Fab' with progesterone, pregnanedione and other related steroids have been grown. The complex crystals have different morphology but are isomorphous with the native crystals. A hydroxy-progesterone derivative obtained by substituting an iodo-benzoyl group at the 11 alpha-hydroxyl position looks promising as a suitable heavy-atom candidate in addition to other potential conventional heavy-atom derivatives. All crystals diffract to at least 2.8 A resolution and are suitable for high-resolution X-ray diffraction studies.
