Introduction: Legislation systems of most countries prohibited using the handheld mobile phone while driving due to the fact that it disturbs concentration and causes hand involvement. Every phone owner is accustomed to the ringtone of his phone and almost involuntarily endeavors to pick it up or check who calls. This engages one’s psychomotor skills, which in our opinion contributes to the attenuation of reaction time needed for performing other crucial functions. Objectives: The aim of the study was: (1) to evaluate the infl uence of the sound of a ringing mobile phone on the complex reaction time (RT) score in healthy subjects (owners), and (2) to check if there are any differences in RT when a landline phone and mobile phone ring. Methods: To assess RT we used our system and protocol of examination, previously validated. The examination conditions were standardized. All tests were performed in the same room with the same light and general acoustic conditions. The test group consisted of 23 women and 24 men, aged 19–24 years. The examination comprised 4 sessions: Training Session (TS) during which the subjects were accustomed with the application and sample stimuli, Control Session (CS) with no telephone ringing, Landline Session (LS) with landline phone ringing, Mobile Session (MS) with mobile phone ringing. Results: The median RT in the study population was signifi cantly elongated (p < 0.001) in MS. In women and in men RTs were signifi cantly longer in MS than in CS and non-signifi cantly longer than in LS. Reaction times in CS, LS and MS were longer in women, however the differences were not signifi cant (p > 0.05). Conclusions: We think that the specifi c ‘bond’ between a person and their private phone can signifi cantly disrupt their attention and thus affect the attention-demanding activities.

Objectives: In Poland, 95% of medical personnel had not received legal education before they completed their studies. Having been given these facts, we have started questioning legal awareness of people providing medical services. Aim of the study: The study aimed at evaluating the knowledge of allergists and pulmonologists. Material and Methods: The group consisting of 328 allergists and/or pulmonologist completed the questionnaire. Results: The participants possess the best knowledge in providing information to patients about their health status (CV1). Sixty nine % of responders replied correctly, and the difference was significant (p < 0.001) in comparison with next aspect referring to the principles of providing medical services following guidelines created by think-tanks and also possibilities to take autonomous decisions by physicians (CV2). The correct answers in relation to CV2 were given by 57% of responders. The third compared aspect was physicians' awareness of patients' right to giving a consent or refusal before undertaking the medical procedure CV3. Only 55% of physicians gave correct answers and the difference was significant compared to CV1 (p < 0.001) as well as CV2 (p < 0.05). Younger doctors showed to have better knowledge than their older colleagues (p < 0.05). Working in urban workplaces proved to be more associated with better knowledge than in rural ones (p < 0.05). Discussion: Insufficient knowledge results in a low quality of provided services and puts the doctors at risk of being liable. The rates indicate that doctors are not aware of the fact that only legal regulations are binding, while standards not published by the Minister of Health are not legally valid. Half of the respondents have the wrong belief that the opinions expressed by experts make the doctor feel exempt from liability. Probably there are specialities, like occupational medicine which are specially linked with awareness of valid legal rules.
