    Notes: Abstract Histamine release from human basophils was investigatedin vitro after removal of cell membrane sialic acid by three different sialidases. Pretreatment of the cells with sialidases fromCl. Perfringens, V. Cholera orInfluenza virus A 2 enhanced histamine release induced by subsequent stimulation of the cells with anti-IgE or the plant lectin Concanavalin A and caused a shift to the left of the dose-response curve for anti-IgE. The enhanced histamine release was reflected in a increased calcium sensitivity, thus suggesting that cell membrane sialic acid might be involved in the calcium fluxes preceeding histamine release. In higher doses the sialidase fromCl. Perfringens caused the cells to release histamine by itself, whereas the sialidases fromV. Cholera andInfluenza virus A 2 in high does inhibited the cell response to Concanavalin A.

    Notes: Summary The 10-year follow-up of the Munich General Practitioner Project was designed as a long-term prospective study to evaluate factors predicting macrovascular and overall mortality in a random cohort of non-insulin-dependent diabetic (NIDDM) patients. Of the original 290 patients (103 males, 187 females, median age 65 years) 92.5 % could be assessed, 103 subjects had died, 58 from macrovascular causes. In an univariate analysis of baseline data, deceased patients, and especially those who died from macrovascular causes had significantly higher fasting blood glucose, HbA1c, von Willebrand-factor protein, urine albumin excretion, and serum β 2-microglobulin, were significantly older, exhibited significantly more ischaemic heart disease (abnormal ECG Minnesota codes), carotid artery and peripheral vascular disease (both determined by ultrasound-Doppler), and had significantly inferior knowledge about diabetes and its treatment. No significant differences were seen for gender, blood pressure, smoking, total cholesterol, triglycerides, HDL-cholesterol, or the use of antidiabetic, antihypertensive or coronary drugs. In a multiple logistic regression analysis, the risk factors for macrovascular death were age, HbA1c and von Willebrand-factor protein. When baseline macrovascular disease was taken into account, carotid artery disease was also a determinant. The main variables from the metabolic syndrome (blood pressure, dyslipidaemia, body mass index) did not enter a multiple logistic regression analysis. The data suggest that age and haemoglobin A1c are major determinants, and that in addition von Willebrand-factor associated endothelial damage is a risk factor for macrovascular mortality in NIDDM patients.

    Notes: Summary The purpose of this study was to compare the effect of hyper-ventilation and indomethacin on cerebral circulation, metabolism and pressures in patients with acute severe head injury in order to see if indomethacin may act supplementary to hyperventilation. Fourteen severely head injured patients entered the study. Intracranial pressure (ICP), mean arterial blood pressure (MABP) and cerebral perfusion pressure (CPP) were monitored continuously. Within the first four days after the trauma the CO2 and indomethacin vasoreactivities were studied by measurements of cerebral blood flow (CBF) (Cerebrograph 10a, intravenous133Xe technique) and arterio-venous difference of oxygen (AVdO2). Ischaemia was evaluated from changes in CBF, saturation of oxygen in the jugular bulb (SvjO2), lactate and lactate/oxygen index (LOI). Data are presented as medians and ranges, results are significant unless otherwise indicated. Before intervention ICP was well controlled (14.8 (9–24) mmHg) and basic CBF level was 39.1 (21.6–75.0) ml/100 g/min). The arterio-venous oxygen differences were generally decreased (AVdO2 = 4.3 (1.8–8.1) ml/100 ml) indicating moderate luxury perfusion. Levels of CMRO2 were decreased (1.54 (0.7–3.2) ml/100 g/min) as well. Duringhyperventilation (ΔAPaCO2 = 0.88 (0.62–1.55) kPa) CBF decreased with 11.8 (−33.4−29.7) %/kPa and ICP decreased with 3.8 (0–10) mmHg. AVdO2 increased 34.0 (4.0–139.2) %/kPa, MABP was unchanged, CMRO2 and CPP increased (ΔCPP = 3.9 (−10−20) mmHg). AVD (lactate) and LOI were unchanged. No correlations between CBF responses to hypocapnia and outcomes were observed. An i.v. bolus dose ofindomethacin (30 mg) decreased CBF 14.7 (−16.7−57.4) % and ICP decreased 4.3 (−1−17) mmHg. AVdO2 increased 27.8 (−40.0−66.7)%, MABP (ΔMABP = 4.9 (−2−21) mmHg) and CPP (ΔCPP = 8.7 (3–29) mmHg) increased while CMRO2 was unchanged. No changes in AVd (lactate) and LOI indicating cerebral ischaemia were found. Compared to hyperventilation (changes per 1 kPa, at PaCO2 level = 4.05 kPa) the changes in MABP, CPP and CBF were significantly greater after indomethacin, while the changes in AVdO2, ICP, SvjO2, and LOI were of the same order of magnitude. Nocorrelation between relative reactivities to indomethacin and CO2, evaluated from changes in CBF and AVdO2, or between the decrease in ICP after the two procedures were found. Thus, some patients reacted to indomethacin but not to hyperventilation, and vice versa. These results suggest that indomethacin and hyperventilation might act independently, or in a complementary fashion in the treatment of patients with severe head injury.

    Notes: Pain and tenderness of masticatory muscles are often related to muscle tenderness elsewhere in the body. It has been shown that women are more prone to musculo-skeletal disorders than men. We sought to determine whether sex differences of muscular symptoms were established by the age of 19. The subjects comprised 51 boys and girls who received a questionnaire regarding the function of their masticatory system, frequency of headache, and neck, shoulder and low back pain. Their masticatory system was examined, and neck and shoulders were palpated. For all variables in the questionnaire girls reported symptoms more often than the boys. Of the subjects 50% had tender chewing muscles upon palpation. Again the girls had the most. There was good correlation between reports of pain in one area as compared to others. The number of clinically tender neck and shoulder muscles correlated with the number of tender masticatory muscles. It was concluded that girls presented more muscular symptoms than boys.

    Notes: In 1978 five cases of so-called hypersensitivity reactions to Scutan® and two to Impregum® were reported (Dahl, 1978). The aim of the present study was to assess whether hypersensitivity or cell-mediated immune reactions were associated with the adverse clinical reactions in these patients or in others who had experienced the same reactions. Epicutaneous patch testing and lymphocyte transformation tests were carried out in a total of 13 individuals. The findings were difficult to interpret, because there was no consistent association between skin reactions and cell-mediated immune responses in subjects with suspected allergies. Other possible reasons for the reactions originally recorded were therefore discussed. It was concluded that adverse reactions associated with immune-mediated, delayed type hypersensitivity reactions may be elicited by prosthodontic materials, but other pathogenic mechanisms and aetiological factors responsible for the reactions observed should also be considered.

    Notes: Twenty individuals received an increased occlusal face height by orthodontic means (a partial bite-raising splint). After splint treatment some of the anterior teeth were capped at the new occlusal face height. The average increase from start of splint treatment till after crown cementation was 1.9 mm. The stability of the vertical relations of the face after this treatment was studied. The average observation time was 67 months, i.e. 5.5 years. The modes of reaction were highly individual. A certain average relapse of the occlusal face height did occur, mostly in the course of the first 6 months after crown cementation. However, in no case did the increased face height revert to basis. In the period from 6 to 67 months after crown cementation twelve out of nineteen patients showed practically completely stable vertical relations.

    Notes: Five cases of tissue hypersensitivity to Scutan and two to Impregum are reported. The reaction to Scutan was a burning sensation in the mucosa in contact with the material, followed by swelling and erythematous ulcers producing heavy discomfort. All symptoms gradually disappeared after removal of the material. To Impregum the reaction was basically the same, only less vigorous since contact with the material is of limited duration. All the cases were women in the menopause. Attention is drawn to the possibility of hormonal imbalance being a factor of importance in the development of hypersensitivity reactions to materials of this sort.

    Notes: The maximal bite force was recorded between antagonizing anterior teeth in a group (n= 10) of patients with pathologic attrition and in a control group. No statistically significant difference between the maximal bite forces was recorded. Also, the effect on the maximal bite force of the continuous wearing of a partial bite raising splint for 4 months was recorded.The great individuality in reaction patterns prohibited simple generalizations.However, in some individuals the maximal bite force was larger when biting on the splint than without, both at base line and after 4 months. Also, the maximal bite force showed a tendency to increase with time.The findings indicate that pathologic attrition is not necessarily associated with a high maximal bite force. Also, the maximal bite force recorded under various conditions is seemingly not an absolute value but rather the result of a number of factors of varying importance for different individuals.
