In this paper we present the results of the investigations of nanostructured C-Pd films for hydrogen sensing applications. These C-Pd films were prepared by physical vapor deposition and then annealed in an argon flow at the temperature of 500°C. The structure and morphology of the prepared C-Pd films were investigated using transmission electron microscopy and energy dispersive X-ray spectroscopy. We studied the infiuence of hydrogen on the electrical properties and crystal structure of C-Pd films. It was shown that film resistance changes depended on hydrogen concentration. At lower hydrogen concentration (up to 2 vol.%), the films response increased proportionally to [H2], while above 2 vol.% H2, it was almost constant. This is connected with the formation of a solid solution of hydrogen in palladium at lower H2 concentration and the creation of palladium hydride at higher H2 concentration. X-ray diffraction was used to confirm the formation of Pd-H solid solution and palladium hydride.
Despite premature sexual contacts among teenagers, young girls are not aware of the consequences. Additionally, they are physically not prepared for the role of mother. Procreation consulting is extremely important, especially for patients under treatment using teratogenic medication. Among the 1250 case histories of girls in the Nephrological Ambulatory of Department and Clinic of Pediatrics in Zabrze, from the years 1999–2009, 4 pregnancies were observed in girls aged 16–18 years. In the current paper three of them are described. Available literature has been reviewed with particular interest on lupus nephritis.

Nastolatki pomimo rozpoczęcia współżycia seksualnego nie są świadome konsekwencji swego postępowania ani przygotowane psychicznie do roli matki, dlatego tak ważne jest poradnictwo związane z prokreacją, szczególnie w sytuacji stosowania leków mających szkodliwy wpływ na płód. Analizując 1250 kartotek pacjentek Poradni Nefrologicznej przy Katedrze i Klinice Pediatrii w Zabrzu w latach 1999–2009 stwierdzono 4 przypadki ciąż u nastolatek w wieku od 16 do 18 lat. W artykule zaprezentowano 3 z nich. Omówiono dostępne piśmiennictwo, ze szczególnym uwzględnieniem nefropatii toczniowej.
