[The effect of an extended initial therapy on molars and single-rooted teeth].
The purpose of this study was to evaluate the benefits of an initial periodontal therapy consisting of a single subgingival root debridement procedure followed by repeated monthly subgingival irrigations over a period of 6 months in 23 patients with multiple advanced periodontal lesions. The clinical and microbiological data of the test group indicated that the applied irrigation scheme was successful in maintaining improvements of periodontal health over a period of 6 months. There were no statistically significant differences in effectiveness between sites in molars and single-rooted teeth. On the other hand, negative controls treated only by a single root debridement procedure displayed a tendency towards pretreatment levels.

[Material study for Aumatic foil technique].
The disadvantage of conventional metal ceramic restorations seems to be the loss of transluszenz and transparency in thin ceramic layers, on behalf of Aumatic-foil an improved aesthetic image is possible. Foil-technique enables the production of metal ceramic crowns with a compressive and shearing forces allowing the appliance to single crown in clinic use. In vitro measurement of the marginal leakage show a sufficient adaptation.

Subgingival irrigation in the maintenance phase of periodontal therapy.
The purpose of this study was to evaluate the effect of subgingival scaling versus subgingival pocket irrigation with 0.1% chlorhexidine or saline controls on the repopulation of subgingival periodontal sites with disease-associated micro-organisms following a single procedure of scaling and root planing. Additionally, pertinent clinical parameters (attachment level, plaque index, bleeding on probing) were also recorded. 375 sites in 30 individuals with previously untreated periodontal disease were thoroughly scaled and subsequently either rescaled, irrigated, or not treated at all for the following 6 months at 1-month intervals. The results show that the initial scaling and root planing procedure led to significant clinical and microbiological improvements in all experimental groups. These improvements were maintained in all but the untreated sites. Based on the observed clinical and microbiological changes, subgingival irrigation of periodontal pockets at 1-month intervals was equally effective as scaling and root planing performed at the same pace. 0.1% chlorhexidine however, being used as test irrigant, was not more effective than saline controls.

Metabolic control and effect on secondary complications of diabetes mellitus by pancreatic transplantation.
After successful pancreatic transplantation blood glucose can be normalized without exogenous insulin, although oral and intravenous glucose tolerance remains impaired in 10-45% of the patients. There is no significant deterioration of glucose control with time in most patients. Since most recipients of pancreatic grafts have far advanced secondary diabetic lesions and the observation time after grafting is rather short, the effects of pancreatic transplantation on these complications are difficult to interpret. However, the development of diabetic nephropathy can be prevented, skin microcirculation improves significantly, while autonomic and peripheral neuropathy and diabetic retinopathy remain stable or improve slightly in most patients. But these ameliorations may be in part due to elimination of uraemia, since in almost all patients combined pancreas/kidney transplantations were performed. It is concluded that pancreas grafting probably has to be performed much earlier in the course of diabetes, although the improvement in the quality of life is striking even in the end-stage diabetics studied so far.

[Status of perfusion scintigraphy in the diagnostic strategy in cerebrovascular disorders and space-occupying lesions].
The results of an evaluation of the perfusion scintigraphy findings of 350 hospitalised neurological patients and 55 more strictly selected neurosurgical patients with cerebrovascular complaints, revealed an accuraty of 83%, a sensitivity of 89%, and a specificity of 83%. The selection of the patients had no influence on the results as a whole. Compared with contrast-medium angiography, incorrect diagnosis must be expected in 17% of the cases. This includes erroneous negative findings in 10% of the cases. Grounds for misinterpretations are suggested, and the biological and methodological limitations of the method are set forth.
