Distribution of muscle activity during sleep in bruxism.

10 outpatients with bruxism were investigated by polygraphic recordings during night sleep. Electromyogram, electrooculogram and electroencephalogram derivations were used to evaluate the activities of masseter muscle and the different stages of sleep. The results of the bruxist group were compared to those of an age-matched control group. The amount and the length of pressing and grinding jaw movements were correlated with the sleep period time as well as with the different sleep stages. In comparison to the control group, a significant difference of muscle activity longer than 5 s was found, but there was no difference regarding activities of 3-5 s duration. The highest level of activity was found in sleep stage two and during awakening times. No difference was seen with regard to percentages of the sleep stages.

[Nocturnal sleep studies of bruxism].

Polygraphic recordings during two nights sleep in 7 selected outpatients prior to and following treatment of bruxism were carried out using EMG-, EEG and EOG-recordings to evaluate the activities of the masseter muscle and the different sleep stages. The results thus obtained were compared to those of an age-matched control group. Following treatment with occlusal splints the recordings were repeated eleven weeks later. The length and the amount of grinding and pressing activities were correlated with the total night sleep as well as with the different sleep stages. The highest incidence of muscle activity was found in stage two and during awakening. Furthermore muscle activities were observed immediately before the beginning of REM-sleep and in particular during the change from REM- to NREM-sleep and in sleep stage one. After treatment with occlusal splints there was a decrease of total muscle activity, thus indicating efficiency of the treatment.

[Has haemofiltration a specific therapeutic effect? A co-operative study involving 20 patients (author's transl)].

In order to evaluate the effects of haemofiltration (HF) on blood pressure control, hyperparathyroidism and hypertriglyceridaemia, the relevant clinical and biological parameters were compared under haemodialysis (HD) and under haemofiltration using a substitution fluid (SF) acetate. Blood pressure control was achieved with HF in only one of 14 hypertensive patients. In 17 patients, with the same doses of Al (OH)3, plasma phosphate levels were similar under HD (63 mg/l) and HF (67 mg/l). In 3 patients, measurements of plasma parathyroid hormone (PTH) levels in the presence of increasing concentrations of SF calcium showed that a concentration of 90 mg/l was required to obtain a positive calcium balance and a decrease in PTH levels. After 6 months, PTH levels under HD and under HF were comparable. In 20 patients, there were no significant differences between HD and HF in mean plasma concentration values of total lipids, cholesterol and triglycerides. Finally, HF was better tolerated than HD in 58% of the cases and less well tolerated in 8%.

Analysis of volatile N-nitrosamines in mainstream and sidestream smoke from cigarettes by GLC-TEA.

Volatile N-nitrosamines were quantitatively determined in mainstream and sidestream smoke of commercial cigarettes using gas chromatography-thermal energy analysis (GLC-TEA). The smoke was trapped in ascorbic acid solution buffered at pH 4.5 and then extracted with dichloromethane; the organic phase was chromatographed on basic alumina and analyzed by GLC-TEA. The mainstream smoke of 22 different commercial cigarettes from Germany and Switzerland contained between 0.1 and 27 ng dimethylnitrosamine (DMN), 1.5 and 29 ng nitrosopyrrolidine (NPY) and traces of methylethylnitrosamine (MEN). The sidestream smoke of these cigarettes contained between 143 and 415 ng DMN, 3.1 and 27 ng MEN and 28 and 150 ng NPY. In a final experiment we measured the DMN concentration in a sealed experimental chamber as a function of the number of cigarettes smoked and recovered 68-87% of the DMN values found when using the sidestream collection device applied in the other experiments.

[Comparative studies on the axial point of the prosthesis].

After marking, the axial point of the temporomandibular joint was arbitrarily determined with a teleradiographic cephalostat according to the Gerber, Ramfjord, Posselt, and Hobo procedure as well as the Whip-Mix-Quick-Mount external arch. The results were compared with the position of the true hinge axis. The distance which this axial point deviated from the axis was measured. Occlusal errors occurring in conjunction with prosthetic and restorative work may be reduced to a minimum if the thinest possible centric tracing is made.
