Body weight gain as the major risk factor of cholelithiasis in women and an important risk factor in man.

PURPOSE: The power of correlation was assessed between chosen risk factors of cholelithiasis in order to establish the ranking of these factors in Podlasie inhabitants. MATERIAL AND METHODS: The study involved 169 patients hospitalized due for cholelithiasis (study group) and 202 patients without cholelithiasis (control group). Previous exposure of patients of both groups to the chosen risk factors of cholelithiasis was evaluated (based on a history questionnaire designed by the authors of the study). Two models of logistic regression were prepared (for men and women) for multivariate analysis. RESULTS: The ranking of the risk factors of cholelithiasis was established by analysing multiple correlation coefficients for the two models of logistic regression and their significance was determined with Wald's test. The significant risk factors for women included: overweight and obesity, age, diabetes, use of contraceptive pills, while for men these were: age, serum triglycerol level, obesity. CONCLUSIONS: The knowledge of risk factors of cholelithiasis in our population is the essence of health promoting actions. Obesity is the major risk factor in women and statistically significant in men. Promotion of appropriate eating habits can result in body mass reduction and may thus indirectly decrease other risk factors of cholelithiasis (incidence of type II diabetes and serum triglycerol level).

The evaluation of parodontium in medical students of the Medical University of Bialystok according to CPITN index.

PURPOSE: The aim of the study was the evaluation of parodontium according to Community Peridental Index of Treatment Needs (CPITN) index in 455 students of The Medical and Dentistry Department of The Medical University of Bialystok. MATERIAL AND METHODS: After the examination, the students filled a survey according to their own project concerning hygienic habits as well as smoking, sweet intake. The results underwent statistical analysis. RESULTS: There were 1334 (48.86%) sextants observed with healthy parodontium in the studied population. Gingivorrhoea was stated in 440 sextants (16.12%), more often in men than in women. Calculus was reveled in 790 sextants (28.94%) of the population. The number of sextants with code 3 was 1.76%. Sextants with shallow pockets were more numerous in women (37 sextants) than in men (11 sextants). Advanced changes in parodontium (code 4) were observed in 9 sextants (0.33%). On the basis of the analysis of treatment needs in the group of 455 students, it can be stated that only 24.62% of the examined subjects did not need parodontium treatment. CONCLUSIONS: The diagnosis of parodontopathy and the factor that can have harmful influence on the parodontium tissues in young people is a superior criterion in the fight with irreversible parodontium changes in adults.

The oral cavity hygiene as the basic element of the gingival recession prophylaxis.

The purpose of the study was the evaluation of the dental plaque and the influence of determined hygienic factors on gingival recession occurrence in 455 students of The Medical University of Bialystok. All the subjects were examined in artificial light, with the use of the probe, mirror, and parodontometer. The distribution of stained dental deposits were estimated with the use of the plaque index according to Quigley and Hein. Moreover, the students were to fill a survey of their own project concerning hygienic habits. The results underwent statistical analysis. The dental plaque was not present in 71 people. Gingival recession was revealed in 134 out of 455 subjects. The majority of medical students brushed their teeth twice a day, using medium hard toothbrush or electric toothbrush with appropriate movements and medium strength while brushing. The frequency of brushing the teeth, hardness of the toothbrush, the use of electric toothbrush, the movements during brushing the teeth, the strength of brushing, the frequency of toothbrush change, the age, and sex have significant influence on the number of recession. The increase in the gingival recession in students is connected with: large pressure on the brush while toothbrushing, too frequent brushing and toothbrush change, the use of hard toothbrush and additional hygienic items, movements while brushing, the age (the number of recession elevates with the age), and sex (women showed more recession than men).

[Chemical elements in hair--biochemical and diagnostic aspects]. / Pierwiastki chemiczne we wlosach--aspekty biochemiczne i diagnostyczne.

Contemporary view related to the mechanism of building--in of metals belonging to the group of bioelements into the hair structure has been presented. Both the practical usefulness of analysis of the hair bioelements in clinical practice and epidemiological studies and a possibility of misinterpretation of the results have been stressed by the Author.
