Using cryopreserved allogeneic pericardium to repair congenital heart defects in children.

Patches prepared from autologous, allogeneic, or xenogeneic tissues are widely used in the repair of congenital heart defects in children. Since 2002, cryopreserved allogeneic pericardial patches have been prepared in our institution as an alternative to commercially available patches. This study retrospectively reviewed donor and patient data concerning cryopreservation time and the clinical use of the pericardium in 382 children who were operated on at a single center between 2004 and 2021.

B cell subsets in healthy children: reference values for evaluation of B cell maturation process in peripheral blood.

Background: The process of maturation of the immune system leads to generation of various lymphoid cell populations having the ability to react in specific way and expressing various markers on the cell surface. The study was set up to establish reference values for B lymphocyte subpopulations in peripheral blood of children and young adults to find the spectrum of their physiological age-related variation.

Methods: Blood samples were taken from 292 children and young adults aged 0-31 years and tested for distribution of B cell subsets.

[The influence of tobacco smoking on the state of dentition and the effect of the chronic periodontitis conservative treatment in periodontology clinic patients at the Chair and Department of Periodontology of the Medical University in Lublin].

Tobacco smoking is a serious health and social problem. The aim of the study was investigation of the influence of tobacco smoking on the state of dentition and effects of conservative treatment of the chronic, moderately advanced periodontitis by comparison of API, SBI, PPD and CAL indices before and after the treatment in smoking and non-smoking patients. Smokers group consisted of 30 people aged 30-48 including 15 men and 15 women who had smoked for more than 10 years, with the intensity of smoking of more than 10 cigarettes a day.

Comparison of the effectiveness of the conservative treatment of the periodontal pockets with or without the use of laser biostimulation.

The use of laser therapy as the agent reinforcing conventional treatment of the periodontal diseases becomes more and more common. In the physiotherapy of the periodontal diseases the biostimulating, laser is eagerly used because of its action which accelerates the healing of wounds and also because of its antioedematous, anti-inflammatory and analgesic action. The aim of work was the evaluation of the influence of laser biostimulation on the change of the periodontological pockets depth after the routine conservative periodontological treatment with additional use of laser biostimulation and without it for two groups of pockets: above and below 5 mm.

Use of Emdogain enamel matrix proteins in the surgical treatment of aggressive periodontitis.

One of the ways of treating of the aggressive forms of periodontitis is the method of guided tissue regeneration using enamel matrix proteins included in Emdogain preparation. The aim of work was clinical evaluation of the complex treatment of those periodontolyses using the above mentioned material as the implant material. 35 intrabony pockets were operated in 11 patients aged 17-50.

The application of Bio-Oss and Bio-Gide as implant materials in the complex treatment of aggressive periodontitis.

In the presented study the results of the complex conservative and surgical periodontological treatment using Bio-Oss implant material and the regenerative Bio-Gide collagen membrane by Geistlich company were subjected to clinical and radiological evaluation. The measure depth of the periodontal pockets PPD was subjected to evaluation, the level of the epithelial attachment CAL and the defect of bone of the alveolar process were observed on radiograms. In all patients the state of oral cavity hygiene was examined using the index of API bacterial plaque and the percent of SBI index of bleeding gingiva.

The use of HA-Biocer in the complex treatment of aggressive periodontal diseases.

The aim of the work was clinical and radiological evaluation of the HA-Biocer implant material in the complex conservative and surgical treatment of the advanced changes in marginal periodontium. Highly statistically important reduction of the attachment loss CAL and pockets depth PPD were obtained.
