[Detection of significant gender differences by odontometry as illustrated by a representative group from Lebanese (East-Mediterranean) population].

This study was conducted on a sample of the Lebanese population. Its aim was to verify differences in dental dimensions between the genders as was found by other authors in other populations. It is concluded that gender dental differences constitute an additional important, though not-decisive element, in identification of courpses.

Managing a traumatic wound in a geriatric patient.

Clinical management of a wound in a geriatric patient requires an understanding of age-related changes in the skin and the knowledge to make appropriate treatment choices. This case study describes clinical assessment and management of a traumatic hip wound in a 75-year-old patient. In addition to addressing his nutritional status by providing supplements, topical wound care preparations, including papain-urea and castor oil/balsam of Peru/trypsin, were used as a conservative approach to address debridement and periwound skin concerns. Extra vigilance is required to assess wounds in geriatric patients to determine proper wound treatment and achieve optimum results. Additional studies to evaluate optimal treatment strategies in the clinical management of traumatic wounds in the geriatric population are needed.

Duration of signals for intertrial reinforcement and nonreinforcement in random control procedures.

In the random control procedure, responding to a conditioned stimulus (target CS) is prevented when the probability of unsignaled, unconditioned stimuli (USs) in the intertrial interval (ITI) is equal to the probability of the US in the presence of the target CS. Three experiments used an autoshaping procedure with White Carneaux pigeons to examine the effects of the temporal duration of signals for the ITI USs (cover CSs) and for concomitant periods of nonreinforcement. In Experiment 1, a short duration cover, but not a long duration cover, resulted in responding to the target CS. In Experiment 2, an explicit CS- cue during periods of nonreinforcement did not affect target acquisition. In Experiment 3, a long CS-, but not a short cover CS, was a sufficient condition for the acquisition of responding to the target CS. These results imply that the acquisition of responding to a target CS requires a discriminable period of nonreinforcement that is long relative to the target CS duration.

[Cytotoxicity of dental filling materials in primary cultured cells derived from human dental pulp (in vitro)].

Primary cultured cells derived from human pulp tissue were used for examining the cytotoxicity of nine commercial filling materials used in restoration and root canal procedures. Cell growth was evaluated by photo pattern analysis, cell nuclei counting, and neutral red uptake. L-strain cells were also used for comparison. Primary cultured cells from either the coronary or radicular part of the pulp tissue were less sensitive to the tested materials, than were L-cells. As for sensitivities over time following mixing of the materials, the cytotoxicity of the three restorative materials was immediately moderate but disappeared 24 hours after mixing. The other six root canal filling materials yielded similar moderate to high cytotoxic levels immediately after mixing and the effects continued. The order of cytotoxicity was: Diaket and Calvital (highest); Pulp canal sealer, AH-26, and Canals (high); and then Kloroperka and three restorative materials (moderate). The differences in cellular reactions between primary and strain cells was considered to be due to cell origin, i.e. diploid or heteroploid. The importance of using primary cultured cells from designated target tissues when evaluating various materials in vitro was discussed.

[Change in the allergen spectrum in contact eczema 1975-1984].

The patch test results in 8247 patients tested in the years from 1975 to 1984 at the Department of Dermatology at the University of Graz were evaluated and a trend analysis was performed. The most conspicuous results were: Increase of contact allergy to nickel in young women; Decrease of contact allergy to chromate; Frequent occurrence of contact allergy to 4,4-diaminodiphenylmethane.

[Use of a new prepared patch in general practice (Epiquick)].

We report on an improved technique of epicutaneous testing. The Finn chambers of the Epiquick system are already loaded with the test material. In a study on 36 patients, the new system was compared with the conventional patch test. The results of both techniques corresponded well for 9 allergens (72.7% at 72 h). Further investigations must settle whether the discrepancies found with some allergens are related to the new system. The simple handling of Epiquick can save considerable time in the patch testing procedure.
