- To evaluate the exocrine pancreatic function at the time of diagnosis of insulin-dependent diabetes mellitus, we determined immunoreactive an-odal and cathodal trypsin(ogen) levels in sera from almost all children (n = 375) 0-14 years of age in Sweden in whom diabetes developed during 1 year, and in sex-, age-, and geographically matched control subjects (n = 312). The median level of anodal trypsin(ogen) was 5 (quartile range, 3-7) µg/L in children with newly diagnosed diabetes, compared with a median level of 7 (quartile range, 4-8) µg/L in control subjects (p < 0.0001). Similarly, the median level of cathodal trypsin(ogen) was 8 (quartile range, 4-10) µg/L in children with diabetes, compared with a median level of 11 (quartile range, 7-15) µg/L in control subjects (p < 0.0001). The median of the individual ratios between cathodal and anodal trypsin(ogen) was 1.4 in the diabetic patients and 1.7 in the control children (p < 0.001). In a multivariate test, however, only the decrease in cathodal trypsin(ogen) concentration was associated with diabetes. The levels of trypsin(ogen)s did not correlate with levels of islet cell antibodies, present in 81% of the diabetic children. Several mechanisms may explain our findings, for example, similar pathogenetic factors may affect both the endocrine and exocrine pancreas simultaneously, a failing local trophic stimulation by insulin on the exocrine cells may decrease the trypsinogen production, and there may be an increased elimination of trypsin(ogen) because of higher filtration through the kidneys in the hyperglycemic state.

- An outline is presented here of the Po Valley Fog Experiment 1989, carried out within the EUROTRAC‐GCE project. This experiment is a joint effort by several European research groups from 5 countries. The physical and chemical behaviour of the fog multiphase system was studied experimentally following the temporal evolution of the relevant chemical species in the different phases (gas, droplet, interstitial aerosol) and the evolution of micrometeorological and microphysical conditions, from the pre‐fog situation through the whole fog evolution, to the post‐fog period. Some general results, useful for describing the general features of the fog system, are presented here, while specific scientific questions on the different processes taking place within the system itself will be addressed in other companion papers of this same issue.

Correlation between dendrite diameter and action potential amplitude in sex pheromone specific receptor neurons in male Ostrinia nubilalis (Lepidoptera: Pyralidae)

Tidskriftsartikel (refereegranskat)abstract
- Outer dendritic segments of olfactory receptor neurons tuned to sex pheromone components were measured morphometrically on the antenna of male European corn borers. Ostrinia nubilalis, to determine if a correlation exists between the diameter of the outer dendritic segment and the spike amplitude. The olfactory sensilla investigated each contained three receptor cells. Two cells were each specific for one of the two pheromone components, (Z)-11-tetradecenyl acetate (Z11-14:OAc) and (E)-11-tetradecenyl acetate (E11-14:OAc). Two strains of cornborers (Z and E) differ as to which of the two pheromone components is the main one. In both strains a large difference could be observed between the spike amplitudes elicited in the receptor cells by the two pheromone components, the main component always eliciting the large spike. In F1-hybrids (EZ) of these two strains, producing both pheromone components in similar quantities, the spike amplitudes were equal in the two pheromone-specific receptor cells. The third cell responded specifically to a behavioural antagonist. (Z)-9-tetradecenyl acetate (Z9-14:OAc) in both the parental and hybrid strains, and always showed the smallest spike amplitude. In a morphometric study, the outer dendritic segments were shown to differ more in diameter between the largest and second largest cell in the two parental strains than in the hybrid strain, while the smallest diameter cell did not differ between the different strains. These results imply that receptor cells with larger diameter produce spikes with greater amplitude. The data also show that all three types of receptor neurons display outer dendritic segments with strong variation in the diameter along the length of the segment, and with a pronounced taper towards the tip.

Aplasia of the right aortic cusp in a neonate : a life-threatening but curable anomaly
- 1991
-
Ingår i: Annals of Thoracic Surgery. - 0003-4975. ; 52:6, s. 30-1329

Tidskriftsartikel (refereegranskat)abstract
- A case of absent right aortic cusp causing serious aortic incompetence in a neonate is reported. A "bicuspidalization" repair broke down within 24 hours, but reoperation with annular enlargement and insertion of a 19-mm prosthetic valve resulted in complete recovery. This rare but life-threatening anomaly of the aortic valve can be recognized with Doppler echocardiography. Valve replacement in conjunction with aortic annular enlargement should be performed as primary repair.

Patient satisfaction with nursing care : evaluation before and after expenditure cutback and intervention at a surgical clinic
- 1994

- After a major cutback in the budget and staffing of a surgical clinic in southern Sweden there was intervention to improve the quality of nursing care and to evaluate the outcome. The intervention consisted of the implementation of: (1) nursing care organized in such a way that it would secure continuity of the nurse—patient relationship, (2) individually planned care by means of diagnostic reasoning, and (3) quality assurance for aspects believed to be connected with quality of care. Patient satisfaction before and after the intervention was assessed by means of a patient questionnaire survey (May 1991; n = 105 and May 1992; n = 137). Patient satisfaction improved significantly in variables related to nursing care viz. overall satisfaction and satisfaction with information and decision making; satisfaction with contact and staff-patient relationship; ward facilities and physical treatment or examinations; and satisfaction with physical nursing care. The results were interpreted to mean that the intervention may have counteracted any negative impact the reduced budget might have had such as the higher patient turn-over and the shorter in-patient periods, and thus seemed to have improved the quality of the nursing care in terms of patient satisfaction.
