The study included 159 girls aged 17-18, students of high schools in the city of Wroclaw. The study was conducted between November 2010 and ay 2011. Girls were divided into 3 subgroups according to the BMI score. Girls' diets were analyzed with the method of a direct interview of the last 24 hours before the test and the interview was repeated seven times. RESULTS The present study demonstrated that the intake of iron from food rations of almost all the girls surveyed was below the requirements defined for this age group. Statistically significant differences were noted in the intake of energy and nutrients among the three distinguished subgroups of girls. CONCLUSIONS Food rations of the surveyed girls were characterized by a low, compared to dietary allowances, calorific value, which resulted in deficiencies of nutrients increasing iron bioavailability.

Background Over 70-95% patients with PR3 ANCA pulmonary vasculitis present with upper respiratory tract symptoms or sings. Nasal cavity usually presents with obstruction and chronic refractory infections (rhinosinusitis) which commonly manifest as bloody discharge or crusting obstruction. Mucopurulent discharge may occur in the acute phase or remission, along with other symptoms suggesting sinusitis. Later on, saddle nose deformities can occur due to collapse of the nasal septum. Other common destruction areas are the maxillary ostia, erosion of the tubinates or damage of soft palate. Objective The aim of the study was to characterize pathologies of nasal and sinonasal CT scans in patients with PR3 pulmonary ANCA vasculitis and to establish the CT diagnostic criteria for WG. Between 2005-2009 sinonasal CT visualization was performed in 35 patients (19 female, 16 male) with PR3 ANCA positive WG. Results Bony destruction of the nasal cavity was revealed in 15 (42.8%), damage or distortion of the paranasal sinuses in 20 (57.1%), the mastoid cells in 7 (20%), and the orbits in 7 (20%) patients. Sclerosing osteitis of the nasal cavity and paranasal sinuses were observed in 11 (31.4%) and in 24 (68.5%), respectively. Bony thickening of the nasal cavity was shown in 5 (14.2%) patients and of the paranasal sinuses in 7 (20%) (unilateral in 2 and bilateral in 5 patients). Seven patients (20%) had orbital masses; all unilateral. Septal perforation was observed in 11 (31.4%) and saddle nose deformity in 7 (20%) patients. Conclusions Maxillary sinuses are regions which are most frequently affected during the course of PR3 ANCA pulmonary vasculitis. CT imagines may be a useful supplement to clinical and activity scoring of WG disease with pulmonary involvement.
