[The analysis of I125 brachytherapy complications in cases of uveal melanoma].

PURPOSE: Analysis of type and frequency of complications after brachytherapy 1125 between 1-12 months after treatment and during the following controls. MATERIALS AND METHODS: 147 persons (76 men and 71 women) aged 23-86 years (mean 57 years), were treated in our clinic in 1998-2001. In 43% of the cases the thickness of the tumor was more than 8 mm and in 94% the maximum diameter was bigger than 8.1 mm. The irradiation dose was 80-120 Gy, mean 100 Gy. RESULTS: Regression and stabilization of the tumor was achieved in 84.3% of all cases. Complications of different type and intensity associated with brachytherapy I125 were observed in majority of the cases. The complications observed were: radiation retinopathy (52%), radiation maculopathy (33.6%), radiation optic neuropathy (25.3%), vitreous hemorrhage (8.8%), glaucoma (20.5%) and cataract (18.5%). CONCLUSIONS: 125I brachytherapy yields good results in cases of uveal melanoma, however it's associated with post radiation complications.

[Optic disc melanocytoma].

PURPOSE: Presentation of the cases of melanocytoma observed in the latest time in our clinic. MATERIAL AND METHODS: We present 2 cases - one in a 41 years old women S.M. and in a 77 years old women P.J. CONCLUSIONS: In case of melanocytoma there should be performed specialistic ancillary tests and the patients should be observed with photographic documentation.

[Air microflora of university cafeteria].

The numbers of aerobic mesophilic bacteria, yeasts and moulds were obtained by sedimentation method. The investigation included six areas, which have been separated on the ground of their function: 1. washing and peeling of potatoes and vegetables, 2. initial treatment of raw materials, 3. washing up of kitchen utensils, 4. cooking of meals, 5. serving of meals, 6. dining room. The samples of air were collected in 32 investigation points in the morning (8-8(30)) and in the afternoon (15-15(30)). Twelve series of measurements were carried out and in general 768 of air samples were tested. The results show that numbers of bacteria, moulds and yeasts were variable and received respectively 75-4550, 0-4565 and 0-290 cfu/m3. Analysis of variance proved that differences between mean number of microorganisms in the air were significant in dependence on the kind of place, time of a day and series of measurements. In the morning the highest microbiological contamination characterized the air of "washing and peeling" area. In the afternoon the number of all groups of microorganisms in the air of 1 and 2 areas was reduced. In the other places the amount of bacteria and yeasts increased, but mean number of moulds was reduced. Respectively 3% and almost 20% of air tested samples not answered for bacteria and fungi numbers recommended to kitchen areas. Filamentous fungi were represented mainly by Cladosporium sp. and Penicillium sp.

[Microbiologic evaluation of instant soup concentrates].

The microbiological condition of instant soup powders purchased in retail network has been assessed. The study included 37 instant soups (8 types) manufactured by four Polish companies. The microbiological quality of a majority of soup powders fulfilled the requirements of the standard. No pathogenic bacteria (Salmonella, E. coli and Staphylococcus aureus) were detected, nor were there any spores of sulphitereducing anaerobic bacteria found. However, some samples of powders, mainly from one manufacturer, did have an excessive total number of bacteria (> 10(5) cfu/g) and a reduced (down to 0.01 g) level of coliform count. Aerobic bacteria occurring in powders were of vegetative and spore forms and exhibited the activity of amylo-, lipo- and proteolytic exoenzymes. The quantity of moulds did not exceed 100 cfu/g in a majority of samples. They were mainly represented by Penicillium sp., Aspergillus sp., Alternaria sp. and Cladosporium sp.

[The evaluation of thermophilic fungi in raw coffee beans].

The purpose of the study was the attempt of the isolation of the thermophilic fungi from raw coffee beans. The material constituted of 24 coffee beans samples came from 12 countries. The isolation and the identification of the thermophilic fungi was conducted according to Biłaj [2], Biłaj and Zacharczenko [3]. The study proved, that raw coffee beans were the rich source of the thermophilic mycoflora. From all tested samples 270 species were isolated. The most refused sample came from Ecuador--81% coffee beans were infected. The most of species (90% from among isolated) were species belonged to the Thermomyces lanuginosus.
