[The influence of orthosilicon acid on traumatic edema of the skin. Introduction]. / Wplyu kwasu ortokrzemowego na obrzeki pourazowe skóry. Doniesienie wstepne.

In the Ward of Children Surgery of the local Hospital 35 children from 0 to 15 years old with burn wounds of skin of different degrees have been treated. In surface, medium-deep and deep wounds regression of oedema, reddening and inflammatory reaction were observed already from 2nd day of treatment. Suppuration of wounds was not observed. It was observed that orthosilicon acid has anti-edematous and cooling (reduces pain) effect, quickens epidermization and shortens the time of appearing of granulation in deep burns. We think that orthosilicon acid is preparation worth further clinical testing of its usage in skin illnesses.

Helicobacter pylori infection in Eastern Europe: seroprevalence in the Polish population of Lower Silesia.

The Helicobacter pylori status of the population of Eastern European countries has not been explored despite the high incidence of peptic ulcer disease and gastric cancer observed in these countries. A seroprevalence study has been performed in Wroclaw, a city of Lower Silesia, Poland, to provide insight into this question. Sera were collected to obtain 50 subjects per 5 yr increment of age. A second generation ELISA kit with a high sensitivity and specificity was used. The results plotted by year of birth show a very high prevalence of H. pylori infection in all adults groups born before 1970 (80-100% positive). In the younger age groups, a dramatic decrease was observed. Because it is now known that most H. pylori infections are acquired in childhood (cohort effect), it can be predicted that the infection rate in the adult population will be much lower in the future compared with that presently observed, and it can be expected that evolution in H. pylori prevalence will have an impact on the rate of gastroduodenal diseases in Poland. Because of the high prevalence, it was not possible to identify risk factors for infection in this population.
