[Diagnosis of coronary stenosis by clinical data and computer-assisted analysis of stress test]. / A koszorúér-szükület diagnózisának felállítása klinikai jellemzök és a terheléses vizsgálat adatainak számítógépes elemzésével.

A probability algorithm (PA) was developed and tested using the clinical, exercise test and coronary arteriography (CA) data of 543 patients (pts) studied with the suspicion of coronary artery disease (CAD). The algorithm was constructed from the data of 361 consecutive pts and tested on a separate group of 182 pts. The two pts groups were comparable in all respect. The sensitivity of Pain the diagnosis of CAD was higher compared to the exercise test alone (73% versus 68%, p less than 0.05). The numbers of variables used for the PA didn't influence of the sensitivity. The authors suggest to use the probability algorithms in the clinical practice.

[Significant bacteriospermia. Value and limits of sperm count in andrology]. / A szignifikáns bakteriospermia. A csíraszámlálás jelentösége és határai az andrológiában.

The data concerning bacteriospermia--are very different in the literature. Asymptomatic andrologic patients, and as control group--patients of the outpatient department for male adnexitis--were studied. Cultivation of aerobic bacteria and mycoplasmas has been recently accomplished by quantitative bacteriological analysis and chlamydia diagnostic. The microbiological screening of 210 andrologic patients ejaculate has given the following results: 19.6% were sterile, 21.0% were colonised by apathogens, 59.1% were positive: 6.2% Mycoplasma hominis, 15.8% Ureaplasma urealyticum, 13.3% Chlamydia trachomatis, 51.9% other aerobic pathogens. 27.6% of samples contained more then one kind of bacteria strains. Quantitative isolation of aerobics and mycoplasmas in both andrological and male adnexitis patients groups showed the following distribution. In the andrologic groups 14.7% of samples contained 10(4) CFU/ml, 9.6% more than 10(4) CFU/ml aerobic bacteria; in the male adnexitis group nearly twice higher values could be observed (20.2% and 19.5%). The distribution of mycoplasma CFU/ml was the following; andrologie group: 20.1% of samples contained 10(4) mycoplasma CFU/ml, 37.5% more than 10(4) CFU/ml; in the male adnixitis group the identical values: 22.9%, 66.9%. Chi 2 statistical analysis showed significant difference ((p = 0.000) in the distribution of data in the two groups. On the other hand both of the groups contained all kinds of bacteriological concentration and even negative cases. Therefore authors suggest more biochemical investigations for detecting inflammatory diseases. Spermaparameters (motility and progressive motility) of andrological patients, divided by sperm concentration (cell number above and under 20 million/ml) and the degree of infection (non infected, slightly infected, and above 10(4) CFU/ml) were significantly different in the seriously infected group by variance analysis (p = 0.000).

[Evaluation of the survival time of complete dentures with a mathematical method]. / A teljes lemezes fogpótlások viselési idejének elemzése matematikai módszerrel.

Based on the number of previous dentures and on the information given by the patients the authors describes a mathematical model for the estimation of the denture survival time. The distribution of edentulousness according to age (based on 9991 patients) shows a regular pattern and can be described by a second degree function. The survival time shows a similar regularity. The application of the Kaplan-Meier method can be used to estimate the survival time calculated only from a single cross-sectional study. This approach uses the survival time of the first set of complete dentures and the average edentulous time of the patients with their second complete dentures as a base for the calculation.

[Investigation of the relationship between the posterior edge of the base of complete lower dentures and the mandibular tuberculum]. / A teljes alsó fogpótlás alaplemezének hátsó széle és a tuberculum alveolare mandibulae viszonyának vizgálata.

Surveying the data published in the literature one can establish that opinions of authors differ concerning the appropriate relationship between complete lower dentures and the tuberculum alveolare mandibulae (TAM). Some authors claim that, following extensional principles, the base of complete lower dentures must fully cover the TAM. Others think that it is enough if the base covers half of the TAM; yet others recommend that the base should merely extend as far as the mesial edge of the TAM. In the present investigations, we tried to find out what the relationship was between complete lower dentures prepared in everyday practice and the TAM. Dentists of the Clinic of Prosthetic Dentistry examined 8346 patients in eight different regions of Hungary over a period of three years. In the present analysis, we discuss the data of subjects wearing a complete lower denture. In the populations concerned, 669 subjects met these criteria. With respect to the relationship between the base and the TAM, we distinguished three groups. The first group was made up by cases where the base extended as far as the mesial edge of the TAM, the second group included subjects whose base reached the medial line of the TAM, whereas the third group comprised patients in whose case the base fully covered the TAM. The relationship between the base and the TAM was examined intraorally, by ocular inspection. The data were analysed with regard to gender and laterality, by the help of the SPSS software package and the chi 2 test. The investigations showed that, in everyday practice, an overwhelming majority (77.10%) of complete lower dentures had a base extending to the mesial edge of the TAM, and it was in a mere 3.9% of cases that the base covered (some of) the TAM. Cases where the edge of the base did not reach the TAM (19.01%) were taken as cases where the dentist disregarded the significance of the relationship between the base and the TAM. The tuberculum alveolare mandibulae is a structure made up by dense fibrous connective tissue that, in most cases, may get displaced over its base and is not pressure resistant, not able to provide a value-like seal and, therefore, not suitables for the extension of the base. Our results suggest that practising dentists have noticed this; furthermore, they have probably also noticed that whenever the base extends as far as the mesial edge of the TAM, leaning against it as it were, it effectively prevents the denture from shifting backwards, i.e. is an obstacle to its anteroposterior displacement.

[Study of the relationship of the mandibular alveolar tuberculum to the occlusal plane at complete lower dentures]. / A tuberculum alveolare mandibulae és a rágósík viszonyának vizsgálata teljes alsó lemezes fogpótlásokon.

The distance between occlusal plane and alveolar crest has an influence on the stability of the lower denture. From the relationship of the occlusal plane to the tuberculum alveolare mandibulae we can conclude on the distance between the occlusal surface of the denture's molars and the alveolar crest. The relationship of the occlusal plane to the tuberculum alveolare mandibulae was examined in 688 patients with complete lower and upper dentures. Results have shown, that in 30.25% the occlusal plane of the lower dentures was at higher level, than the highest point of the tuberculum alveolare mandibulae, in 41.3% it was at the level of the highest point of the tuberculum alveolare mandibulae and in 28.45% it crossed the tuberculum below its highest point. From our results the conclusion can be drawn, that in most of the cases no attention to the tuberculum line, has been paid the interalveolar distance and the occlusal plane of the natural teeth at the set-up of the molars, so this has a negative effect in 69.5% of the examined cases on the stability of the lower complete dentures.

[Prosthetic implications of dental screening tests of adolescents]. / Serdülökorúak fogászati szürövizsgálatának protetikai vonatkozásai.

The 700 teen-agers of 14 to 19 years of age observed in the course of national dental screen tests between 1985 and 1989 showed 1198 edentulousness and 154 destroyed teeth. Dental appliances were prepared but for 33 juveniles which, in case of 14 persons, were covering crowns or pin teeth while with 19 thereof it were bridges. Thereby 3.25% of the existing deficiencies were replaced. Removable dentures have not been prepared at all although it would have been justified.

[Evaluation of distal free-end dentures and partial plate dentures based on their effect on the remaining dentition]. / A sorvégi foghiányokat pótló disztálisan szabadvégü hidak és a részleges lemezes fogpótlások értékelése a maradékfogazatra gyakorolt hatása alapján.

The data of 3778 examined persons were processed. The effect of distally free end bridges made for replacing terminal endentulousness on the remaining teeth was compared with the condition of the remaining teeth of patients untreated, provided with partial dentures as well as with combined fix + partial denture. It was ascertained that in cases of replacements by distally free end bridges deterioration of the remaining teeth is essentially less.

[The dental status of elderly people in Hungary--based on mass screening]. / Az idóskorúak fogazati állapotának jellemzói Magyarországon, szúróvizsgálat alapján.

Twenty-three % of the Hungarian population was older than 60 years at the time of this epidemiological survey. This ratio increases gradually. So it is important to know the dental status of this population both from a professional and national health service point of view. The authors have evaluated the data of the dental health state of 2466 persons who were older than 60 years. The data were collected between 1986 and 1989. 1.8% of them kept all their teeth, 38.5% had no teeth at all. The average number of teeth was 3.49 on the upper and 4.57 on the lower jaw. 4-5% of the remaining teeth had caries. The ratio of filled teeth was 3.7% (male) and 6.8% (female). Periodontal problems were diagnosed in 34.2% (male) and 26.1% (female) of the patients. In 57.5% (male) and 73.0% (female) of the missing teeth were replaced. The cases where a large number of teeth were missing (class 2A, 2B, Fábián and Fejérdy classification) were quite often only partially treated.

[Cantilever bridges--a cross-sectional study]. / A disztálisan szabadvégú rögzített fogpótlások néhány jellemzóje szúróvizsgálat alapján.

Life expectancy and functional performance of the cantilever bridges is determined by the length of the cantilever pontic(s) and by the number and localisation of the abutment teeth. No overall epidemiological survey covering this topic was found in the literature. 529 distally cantilevered bridges were evaluated by the authors. There were 310 upper and lower cases. The following parameters were recorded: length of the cantilever part (number of units), the relationship of the cantilevered pontics and the bridge, and the position of the fixed restoration in the dental arch. Previously the cantilevered bridge design was not accepted in Hungary but in spite of this fact a large number of distally cantilevered bridges were made in the country. Most of the examined cantilever bridges are properly designed: two abutments are supporting one pontic (342 cases, 65.56%). However some of the solutions are too risky: one abutment, one cantilevered pontic (110 cases, 20.45%), or two abutments, two cantilevered pontics (53 cases, 9.85%).

Candida guilliermondii var. guilliermondii infection in infertile women.

The sera of 263 women--217 infertile and 46 pregnant--were examined by various serological methods (precipitation test, agglutination, indirect immunofluorescence) to detect Candida guilliermondii var. guilliermondii (C.g.) infection. The precipitation reaction was performed with extracellular C. guilliermondii antigen, the agglutination reaction was employed parallel with C. albicans. In the infertile group 122 (56.2%) proved to be C.g. positive, while in the fertile 11 women (23.9%) proved to be so, the level of significance being p less than 0.0001 between the two groups. A one-month ketoconazole treatment (one tablet, 200 mg/day) was adequate for eliminating the C.g. infection. In a few cases hystological examinations were also performed according to Gomori-Grocott and yeast cells could be detected in the stroma of the ovary. IgA, IgG, IgM, Gc-globulin, transferrin and ferritin determinations were carried out before and after the ketoconazole treatment, and there were significant differences in the IgM and transferrin levels between the infected and non-infected groups. The authors achieved 5 pregnancies of 56 treated women in 6 months.
