The results of 8 years of combined caries prophylaxis (fluoride tablets in school, brushing with aminofluoride gel, motivation of teachers, pupils and parents) are reported from the community of Massagno TI. Caries reduction of about 60%, or from 2.72 new lesion to 1.12 new lesion per pupil and year. About 60% of pupils did not require dental treatment in the year 1977/78. Root canal treatment and fillings of anterior teeth have all but disappeared. MO and MOD fillings have receded more than occlusal fillings. The community and the canton have economized some SFr. 20000.-per annum.

A previous study of the MOD-MEM test showed promising results. We have attempted to repeat the study using a blind coded series of 210 blood samples from normal subjects and patients with either benign or malignant disease. Using standard criteria the false negative rate for cancer patients averaged 43% and the false positive rate for non-cancer patients averaged 34%. The results indicate that the test at the present time, under routine laboratory conditions, is not reliably reproducible and does not have the ability to effectively discriminate between benign and malignant disease. It is suggested that blind coded studies be used more frequently in assessment of tests with cancer detection potential.

An account is given of the present conception of asymptomatic (chemical) diabetes in the pediatric age group, which also has been named MODY (maturity-onset type of diabetes of young people). Long-term studies show that about 10% will eventually decompensate to overt diabetes. In contrast to classical juvenile-onset type of diabetes the inheritance of MODY seems to be autosomal dominant in many cases. Some authors have suggested that insulin resistance exists in non-obese patients with asymptomatic diabetes, but this view is not supported by observations of the author. Obese patients should reduce their body fat, but other therapeutic approaches are difficult to evaluate because of the normal fluctuation of the disease. There is no general agreement in the literature concerning the value of insulin treatment. The author supports the view that insulin treatment should be started in the late stages of chemical diabetes just before symptomatic disease emerges. In the long run this approach may ameliorate the condition due to the preservation of some beta-cell function for long periods. An unsettled question is whether early insulin treatment in asymptomatic diabetes will delay diabetic vascular complications.

Vibration, applied at the beginning of cementation, improves the fit of MOD inlays and cast complete crowns when they are compared to the same castings cemented without vibration. The Medart pressure applicator produced better adaptation. Orange wood blocks and Burlew disks produced similar results. They were less efficient than the Medart pressure applicator. Cotton rolls resulted in the highest fit discrepancy.

Previous work has suggested that impaired islet glucose recognition occurs in patients with adult onset diabetes, as acute insulin release is absent after iv glucose but present after beta adrenergic stimulation with isoproterenol (Iso). However, insulin responses to Iso were variably reduced as compared to normal in the diabetics. In order to evaluate the importance of the Iso dose, dose-response studies were performed in 9 diabetics (fasting plasma glucose greater than 150 mg/dl) and 10 age-matched controls. In both control subjects and diabetics, 0.5 microgram Iso produced no insulin response; 2 micrograms Iso produced an intermediate response; and 8 and 12 micrograms Iso produced a higher response. The insulin responses to the larger doses of Iso were lower in diabetics than control subjects (8 micrograms, 20 +/- 5 vs. 39 +/- 6 (P less than 0.025); 12 micrograms, 21 +/- 6 vs. 37 +/- 4 (P less than 0.05); means +/- SEM, microU/ml). Of 16 diabetics who received 12 micrograms Iso, 5 had insulin responses greater than 2 SD below the control mean, while others had responses that spanned the entire range of normal. Seven diabetics also were given iv secretin (150 U). Their insulin responses to secretin correlated with the responses to Iso (r = 0.83, P less than 0.02). Thus, patients with subnormal responses to Iso also had low secretion responses. The abnormalities of acute insulin secretion in diabetics can be explained by a lesion variably affecting islet membrane receptors; some patients may have glucose receptor damage, but intact responses to other stimuli, and others may have more widespread damage affecting beta-adrenergic and secretin responses as well. Alternatively, there may be heterogeneity in adult onset diabetes, as patients with low responses to all stimuli could have a qualitatively different lesion affecting insulin secretory capacity rather than membrane receptors.

The idea that the gene(s) that cause diabetes mellitus can be expressed in extrapancreatic cells has been examined by tissue culture techniques. Skin biopsies were obtained from 25 normal subjects (N), 26 overt diabetics (D), 16 of juvenile onset (JOD) and 9 of maturity onset (MOD), and 21 subjects genetically predisposed to diabetes (P) on the basis of maturity-onset diabetes in both parents. Each biopsy was subdivided, multiple skin fragments were explanted in vitro, and several parameters of cellular outgrowth were monitored in primary and secondary cultures until cell division ceased because of senescence. In general, the rank order of growth vigor was N greater than P greater than D although differences were often marginal and statistically significant between N and JOD and(or) MOD. Outgrowth of epithelial cells was more vigorous in N explants in early stages, but later, JOD and MOD cells grew better than those of N. Outgrowth of fibroblast cells from N explants was more vigorous both at early and later stages and required less time to achieve maximum percent outgrowth. In secondary cultures, N cells grew faster than the other three groups so that fewer days elapsed between subcultures but significant differences were only seen between N and one or two of the other groups over some of the first seven subcultures. The onset of cellular senescence occurred earlier in P and JOD cultures both in mean population doublings and calendar time. N cultures had a higher percent surviving clones after picking than MOD, and a shorter recloning time than clones of JOD. The replicative life-spans of cultures (mean population doublings +/- SE) were N = 52.54 +/- 2.24, P = 47.84 +/- 2.43, JOD = 47.12 +/- 2.99, and MOD = 46.40 +/- 4.04, but differences did not reach significance for N vs the other three groups. The data demonstrate that cellular growth is impaired in both JOD and MOD types of cultures and to a generally lesser extent in P cultures. This is consistent with intrinsic genetic defects but the possibility that persistent deleterious effects of in vivo pathophysiology contribute alone or in combination cannot be ruled out. Therefore, the diabetic defect(s) can be expressed in extrapancreatic cells of mesenchymal origin. This system should prove useful in exploring the interplay between genetic and environmental factors in diabetes, the mechanisms(s) of hyperglycemia and other metabolic derangements, and the propensity that affected individuals have to develop degenerative diseases.

The question was investigated whether mitochondria in the mammalian skeletal muscle fiber syncytium incorporate gene products encoded by one or many nuclei. Mouse chimeras were produced from strains which differ in their electrophoretic variants of the nuclear-coded mitochondrial protein, malic enzyme (MOD-2, E.C. 1.1.1.40, L-malate NADP+ oxidoreductase decarboxylating). The MOD-2 phenotypes of skeletal muscles of these chimeras were characterized in a starch gel electrophoretic system. The results indicate that individual mitochondria can contain products encoded by multiple nuclei and therefore that, for skeletal muscle mitochondria, the cell is not subdivided into nuclear territories. Possible mechanisms of gene product distribution in skeletal muscle fibers are discussed.

In a family with maturity-onset type of diabetes mellitus inherited as a dominant, autosomal trait (MODY), the HLA genotypes were compared with the glucose tolerance and the plasma insulin response to oral glucose. In the members with impaired glucose tolerance, the plasma insulin response was of the insulino-tardic type, while those with normal or borderline glucose tolerance had a normal plasma insulin response. HLA tissue typing for A, B, C and D series antigens carried out in 19 of the members showed no association between specific HLA antigens and imparied glucose tolerance. Moreover, when analysing the segregation of the disease and the HLA characters, several recombinants between MODY and HLA would have to be postulated if the gene(s) for this form of diabetes mellitus should be closely linked to the HLA locus.

The frequency of HLA BW54 and B5 in Japanese patients with JOD is increased and decreased, respectively. In JOD patients without a family history of MOD, the frequency of BW54 is significantly increased, whereas in JOD patients with a positive family history the frequency was not increased in a statistically significant manner.

Physical training is useful as a therapeutic means to obtain a decrease in body fat. The success in terms of lost fat is dependent on the ability to adhere to the programme, and probably also on regulatory factors associated with the degree of filling of adipose tissue (adipocyte volume). The rate of weight loss is usually slower than with dietary treatment but physical exercise may be more successful and less uncomfortable in the long run as a means to lose weight and prevent regaining it. Physical training is also effective against the metabolic complications associated with obesity such as decreased glucose tolerance, hyperinsulinemia and hypertriglyceridemia and should therefore be a method of choice to prevent or treat adult onset diabetes mellitus and endogenous hypertriglyceridemia in obesity. The feasibility of training in different groups of subjects seems to be dependent on, among other factors, selection of subjects and design of the training programme.
