Frequency distribution of individuals aged 20-70 years according to severity of periodontal disease.

This study is an analysis of the findings in an epidemiologic investigation covering a random sample of 600 individuals aged 20-70 years resident in the city of Jönköping, Sweden. The frequency distribution of individuals according to severity of periodontal disease was determined. The analysis was based on clinical registration of gingivitis, pocket depths and qualitative and quantitative changes of the alveolar bone in a full mouth intraoral survey. In the age groups 20 and 30 years, 96% and 85% of the individuals, respectively, had healthy periodontal tissues or were grouped as having gingivitis without signs of lowering of the periodontal bone level. In the age groups 40, 50 and 70 years none of the subjects was free from signs of gingivitis/periodontitis but, as for all age groups, strikingly few cases (at most 8%) of severe destructive periodontitis were found. The need for periodontal treatment is discussed as well as the role of specific etiologic agents in the development of destructive periodontal disease.

Improved economics of HBsAg screening with commercial radioimmunoassay reagents.

Commercial 125I anti-HBs was processed to yield a sixfold improvement in economy without significant loss of sensitivity or specificity. Additional polystyrene beads were coupled with commercially supplied anti-HBs. The modified assay (Mod-RIA) was compared with commercial RIA, EIA, and RPHA using established HBsAg panels. Mod-RIA was also compared with HEPATEST (RPHA) for screening 71 200 fresh blood donations during an 11.5-month period.

[Diagnosis and first aid in stroke during the prehospital phase].

In the GDR the apoplexy occupies the 4th place in the statistics of causes of death. It is an acute pathological process and has a firm place in emergency medicine (urgent home visit service and urgent medical aid). The symptomatology is multiform and under ambulatory conditions it may lead to considerable differential-diagnostic difficulties. In the present paper references are given taking into consideration the anamnesis (factors of risk), the clinical examination of the patient, first differential-diagnostic aspects, therapeutic methods resulting from this and suitable possibilities of hospitalisation.

Age differences in visual and kinesthetic short-term memory.

30 elderly subjects were matched with 30 young subjects and tested on a kinesthetic short-term memory task which required the replication of criterion moves after a variable retention interval under conditions of either rest, differing interpolated movement tasks, or mental activity. A visual control condition was used. Differing interference and temporal decrements were observed. Both old and young subjects differed significantly between sighted and blindfold conditions; however, there was no difference between the performance of the old and the young in the blindfold (kinesthetic) condition. These findings were discussed with respect to practical implications for the retraining of old subjects on certain motor tasks.

Susceptibility to erythromycin of anaerobes of the genera Bacteroides, Fusobacterium, Sphaerophorus, Veillonella, Clostridium, Corynebacterium, Peptococcus, Peptostreptococcus.

The minimal inhibitory concentrations (MIC) of erythromycin were determined by broth dilution tests for 313 anaerobic strains, most of which were clinical isolates. All the gram-positive anaerobes tested (84 Peptococcaceae, including 21 Peptostreptococcus anaerobius and 15 Peptococcus variabilis; 65 Corynebacterium acnes and 29 Clostridium strains, including 13 C. perfringens) were sensitive (MIC values 0.012 through 3.12 microgram erythromycin/ml); so were 111 cultures of gram-negative anaerobes (52 Bacteroides fragilis, 12 B. thetaiotaomicron, 7 B. vulgatus, 13 B. oralis, 4 B. melaninogenicus, 10 Sphaerophorus necrophorus, 2 Veillonella sp., 11 members of other species). Erythromycin at concentrations of 6.25 through 200.0 microgram/ml was active against 24 strains (1 B. fragilis, 4 Fusobacterium fusiforme, 9 Sph. freundi, 10 Sph. varius). The present results are compared to the limited number of reports existing with regard to the susceptibility of anaerobes to erythromycin.

[Diagnostic and therapeutic aspects of subarachnoidal hemorrhage from the viewpoint of emergency medicine].

The subarchnoidal haemorrhage is an acute disease which has a high lethality and, therefore, in every case presents an indication for admission into an intensive-therapeutic department. It often occurs in younger age groups and appears more frequently than is assumed in general. Despite impressive clinical symptoms (suddenly beginning stabbing headache, vomiting and disturbances of consciousness of various degree of severity) the picture of the disease is not exactly diagnosed almost in every case. From 1970 to 1974 we treated 105 patients with subarachnoidal haemorrhages. In this paper is referred to the most important clinical and paraclinical parameters. Diagnostic and therapeutic possibilities are discussed.

[A contribution to acute glutethimide (Elrodorm) intoxication].

Following a short discussion of hitherto known facts about glutethimid intoxications, two own cases are described. In these cases minimal amounts (2.5 and 5 g) caused haemorrhagic diatheses and acute insufficiency of the liver, which in one case were combined with acute renal insufficiency. Possible causes are discussed.
