[Organophosphate poisoning in inexperienced workers].

Organophosphates are frequently used as insecticides in agricultural areas, therefore they may pose a risk for accidental exposure by dermal contact or through inhalation. We present the cases of eight young men, who worked unprotected and inexperienced with organophosphates. They were exposed dermally and developed mainly gastrointestinal symptoms and also diaphoresis, hypersalivation, blurred vision and miosis. One patient developed severe weakness, fasciculations, disorientation and sleepiness. All had low levels of plasma acetylcholinesterase. All were admitted to the hospital and received antidotal treatment of atropine and toxogonin. They were released after 48 hours in good physical condition. The hospital staff rapidly diagnosed the organophosphate intoxication; additional doctors and nurses were called to the emergency department. The patients were decontaminated in showers within the hospital. This case emphasizes the need for workers handling pesticides, to be supervised by an experienced person and the advantages of hospital drills in rapid diagnosis and preparedness to provide treatment to many patients.

Down-regulation of surface antigens recognized by systemic lupus erythematosus antibodies on embryonal cells following differentiation and exposure to corticosteroids.

We have previously suggested that anti-DNA antibodies present in systemic lupus erythematosus patients can bind directly to tissues as a result of cross-reactivity with embryonal tissue-based antigens. Here we have analyzed the interaction between polyclonal and monoclonal mouse and human lupus autoantibodies and an embryonal cell line. We report that a murine embryonal stem cell line (ES) expresses a surface antigen which is recognized by mouse and human lupus autoantibodies. This surface antigen is down-regulated following maturation of the cells or incubation with corticosteroids. Adhesion molecules may serve as the target membrane antigen in ES cells since preincubation with these antibodies decreases the ability of ES cells to adhere to the plate.

The urine of SLE patients contains antibodies that bind to the laminin component of the extracellular matrix.

Direct immunofluorescence of tissues derived from patients affected with SLE demonstrates antibodies bound to the extracellular matrix (ECM). In the present work we have tested whether such antibodies are found in the serum and urine of lupus patients and mice. We found that the urine of patients with active SLE and of MRL/lpr/lpr mice contains antibodies that bind ECM and that a major target for these antibodies is the 200 kDa light chain of laminin which is one of the matrix components. The level of the anti-ECM, anti-laminin antibodies correlates with disease activity.

[Delayed pressure urticaria: therapeutic response to cetirizine].

We describe a 39-year-old man who suffered from delayed pressure urticaria for 2 years. His severe symptoms did not respond to antihistamine (H1 and H2) treatment and corticosteroid therapy was given despite severe side-effects. A new, nonsedating antihistamine drug, cetirizine, relieved most of his symptoms, enabled him to be weaned from corticosteroid therapy, and restored his former quality of life.

Embryonal germ-layer antigens: target for autoimmunity.

Histopathological analysis of some systemic autoimmune diseases and syndromes led us to the conclusion that the common feature of the organs involved might be their embryonal origin. We suggest that organs derived from the same germ layer express common germ-layer-specific antigens. Such antigens could serve as target antigens for the autoimmune response.

Quality of sleep in the medical department.

The quality of sleep in 134 patients admitted to two medical departments and an intensive coronary care unit was studied by comparing pre- and post-admission sleeping scores. Four aspects of sleep have been evaluated: duration of sleep; number of awakenings; personal assessment of quality of sleep; and the need for using sleeping pills. Results were expressed in scores ranging from 1 (worst) to 4 (best). A significant reduction in the mean quality of sleep for the entire group was found for all scores employed (P < 0.01-P < 0.001). Of the 134 patients, 51% had a reduction in post-admission total sleep score (23 +/- 3%, mean +/- SE); 31% had no change or mixed trends in the various scores, with a change in total sleep score not exceeding 3 +/- 3%; and 18% had an improved total sleep score (16 +/- 2%). Of the individual scores, a deterioration was found in the following order of frequency: number of awakenings (37%); personal assessment of quality of sleep (32%); duration of sleep (31%); and the need for using sleeping pills (26%). Of the reasons specified for impaired quality of sleep, the most important were noise made by other patients or by the medical staff (47%), and the patient's own disease (30%). Significant differences in the quality of sleep between the two medical departments located in different hospitals have been encountered (P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
