Psychological profile of Greek doctors: differences among five specialties.

The aim of the present study was to explore the differences in the psychological profiles between genders and different specialties among Greek doctors. Five-thirty nine doctors in five different specialties, namely 115 general practitioners, 168 internists, 81 surgeons, 108 microbiologists and 67 anesthesiologists, participated in the study. 253 participants were specialized doctors and 286 participants were medical residents. The sample consisted of 280 women and 259 men. The mean age of the sample was 38.75(±7.98) years. A cross sectional survey study was conducted. Symptom Check List 90-Revised (SCL-90-R) was used to collect the data. Multivariate Analysis of Variance indicated the significant effect of specialty (Wilks' Lambda = .20, p = .000), the effect of gender (Wilks' Lambda = .90, p = .000) as well as their interaction (Wilks' Lambda = .68, p = .000) on participants' scores in SCL-90-R subscales. Internists reported high scores in 8 out of 9 subscales of SCL-90-R. Surgeons scored significantly higher compared to all other specialties in hostility(HS) subscale. Women reported statistically higher scores in almost all subscales of the SCL-90-R test compared to men, apart from HS (p = .191). Gender and specialty choice play role in the psychological profile of Greek doctors. Women and internists seem to be more prone to psychopathology. These findings should be taken into account in future studies and interventions.

Effect of amiloride in human and sheep parietal pleura.

The fluid and solute transport properties of human parietal pleura were studied and compared with sheep parietal pleura in vitro. The pleura was mounted as a planar sheet between Ussing-type chambers. The results presented are the mean values of nine different experiments. The transepithelial electrical resistance (R(TE)) of both pleurae species was measured before and after the addition of amiloride in both sides of pleura. The R(TE) for human was 25.74 +/- 1.23 Ohm x cm(2), while for the sheep it was 38.18 +/- 0.83 Ohm x cm(2). The addition of amiloride to the serosal bathing solution increased the R(TE) of human pleura to 30.48 +/- 1.01 Ohm x cm(2) and sheep pleura to 40.32 +/- 0.82 Ohm x cm(2), while amiloride had no effect on the basolateral side. From the above, it is strongly suggested that the human pleura seems to be more leaky than sheep pleura. Although the R(TE) was increased in both pleurae, the elevation in human pleura was significantly higher, thus results from experiments in sheep pleura could only partly be extrapolated in human pleura.
