Custodians climb career ladder through intensive training program.

The training program for custodial staff at the University of Houston provides continuing education and opportunities for advancement for minority women, who make up approximately 90 percent of the staff. The training and opportunities offered may be responsible for the low turnover and absenteeism in the custodial services department.

The Cheshire Cat effect.

Designing a binocular-rivalry exhibit for the Exploratorium resulted in the observation of some interesting phenomena. Under conditions of binocular rivalry, motion in the field of one eye can trigger suppression of the other visual field as a whole or in parts. This suppression sometimes occurs only in the area of motion. Subparts of a suppressed area often remain in the visual field. Conversely, moving an object into the suppressed area of a visual field can elicit dominance of that object alone, with the rest of the field remaining suppressed. The suppression of partial areas of the visual field of each eye can occur simultaneously.

[Frequency and pathogenesis of epitheloid cell granuloma in Crohn's disease (author's transl)].

12% of the rectal biopsies (19% of the patients) showed epitheloid cell granulomas in clinically definite Crohn's disease. In colonic biopsies such granulomata were visible in 14% (22% of the patients). Granulomata were scarcely seen in normal or slightly inflamed mucosa. They were mostly found together with crypt abscesses and/or erosions and ulcers. The combination of local inflammation around crypts and crypt abscesses is rather characteristic for Crohn's disease. The inflammatory colonic alterations, visible in crohon's disease, may have the following pathogenetic sequence: Local colitis-crypt abscess--destruction of the crypt with proliferation of enlarged histiocytes--transformation histiocytes to epitheloid cells and Langhans cells--epitheloid cell granuloma.

Platelet kinetics in Crohn's disease.

The pathogenesis of thrombocytosis in Crohn's disease was analized in ten non-treated patients using the 51Cr labelling method. The data obtained were compared to those taken from a control group. Besides platelet survival time, platelet turnover, surface radioactivity, platelet adhesiveness and morphological aspects of bone marrow were investigated. Platelet survival time in patients with Crohn's disease proved to be significantly shortened (p less than 0.001), whereas platelet turnover appeared augmented. No additional radioactivity is encountered from the organs scanned. The relative platelet adhesiveness is diminished while thrombocytopoesis in bone marrow is augmented.

Spontaneous extrusion of intraocular foreign body after 11 years.

A case of spontaneous extrusion of intraocular foreign body after 11 years is presented. Despite being magnetic and containing mostly iron the foreign body could not be removed in repeated magnet trials. It was retained in the ciliary body region for a very long time without causing siderosis. The foreign body was spontaneously extruded without any signs of intraocular inflammation.

Fundus lesions in rheumatoid arthritis.

Cotton wool exudates were found in a patient during a flare-up of seropositive rheumatoid disease with polyarthritis and pericarditis. After therapy with cortisone a concomitant improvement of the cardiac arthritic and fundal lesions was observed. It is suggested that the fundal lesions in this patient were due to the rheumatoid disease.

[Lysozyme levels in chronic inflammatory bowel diseases (author's transl)].

Lysozyme concentrations in serum and urine were determined in 101 patients with Crohn's disease and 26 patients with ulcerative colitis. Lysozyme was assayed according to the lysoplate method of Osserman against a standard of humam lysozyme. The mean serum lysozyme concentrations (+/- S.E.M.) for each group were as follows: controls 8.4 +/- 1.8 (n equals 38), Crohn's disease 8.2+/-2.6 (n equals 101), ulcerative colitis 8.7+/-3.0 (n equals 26). No significant differences were found in serum lysozyme levels of the various groups of patients (2p is greater 0.05). There existed no correlation (r equals 0.12, n equals 129, p is greater than 0.05) with the activity of the disease. Serum lysozyme levels were significantly higher in patients affected by Crohn's disease of the small and the large bowel than in patients with involvement of the small intestine only and operated patients (2p is less than 0.05). The discriminative value of these findings with respect to the clinical course of such patients is limited because no significant differences are found between the levels of patients with Crohn's disease and controls. Neither in case of Crohn's disease nor ulcerative colitis were the mean urine lysozyme concentrations increased. These findings show that the determination of serum and urine lysozyme levels is unsuitable in respect of the differential diagnosis of inflammatory bowel disease as well as of the assessment of activity and extent of the disease.

Conjunctival flora in patients receiving immunosuppressive drugs.

The bacterial, fungal, and viral flora of the conjunctiva were compared in patients receiving immunosuppressive drugs and in a control group of patients seen for routine eye examinations. The lysozyme concentration of the patients' tears was also measured. No significant difference was found in the number of positive cultures nor in tear lysozyme content in the two groups. A positive correlation was noted between increasing doses of prednisone and the number of bacterial organisms found in the patients' conjunctiva.
