Consumption of Dairy Products and the Risk of Developing Breast Cancer in Polish Women.

Lack of consistency in the relationship between dairy products consumption and breast cancer (BC) risk motivated us to evaluate this association in a case-control study of BC among Polish women. The study includes 1699 women 26-79 years of age, 823 BC cases identified in Cancer Registries and 876 randomly selected controls from the national population registry. Using a validated, semiquantitative food frequency questionnaire (FFQ), the consumption of dairy products was collected for a time period of 10-15 years prior to BC diagnosis.

Cholesteatoma-associated pathogenicity: potential role of lysosomal exoglycosidases.

Unlabelled: The enzymatic profile of lysosomal exoglycosidases in middle ear cholesteatoma has not been well known. The assessment of glycoconjugate catabolism may contribute to a better understanding of cholesteatoma pathogenesis.

Objective: The study aim was to evaluate catabolic processes of glycoproteins, glycolipids, and proteoglycans in cholesteatoma through outlining the concentration of N-acetyl-β-hexosaminidase (HEX), β-glucuronidase (GLUC), and β-galactosidase (GAL) activity as well as in serum of cholesteatoma patients and healthy volunteers.

[Taxan induction chemotherapy and concomitant chemoradiotherapy with cisplatin in patients with locally advanced head and neck cancer--early results].

Unlabelled: The growing number of patients with head and neck cancer is a reason to search for new effective treatment strategies. Results of treatment for locally advanced squamous cell head and neck cancer with surgery and/or radiotherapy are still unsatisfactory. During last decade concomitant chemoradiotherapy became a new standard in this group of patients.
