The dynamic development of biobanks causes some ethical, social, and legal problems. The most discussed problems are obtaining informed consent, especially for future research, from minors and from deceased people. The aim of this article is to present the current standards held by Polish biobanks concerning obtaining a participant's informed consent in some aspects. ⋯ The practice and rules for obtaining informed consent for the scientific research require improvement. The possibility to use the human materials in the future, conditions for getting access to the data, the possibility of their withdrawal from the database and using the materials and data after the death of the donor should be clearly determined when the informed consent to collect the material is obtained.

Induced sputum is widely used in clinical practice and scientific studies. This technique has become enormously useful in assessment of airway inflammation. However, some asthmatics are unable to expectorate sputum of sufficient quality and quantity necessary for further processing, therefore not providing reliable results. This research study aimed to examine whether asthma control and asthma quality of life influence the results of sputum induction. ⋯ The study results suggest that successful sputum induction may be expected in patients with better asthma control and better quality of life.

Migraine can cause headache in different communities so that 12-15% are suffering worldwide. Recently the relationship between infectious diseases such as Helicobacter pylori infection and migraine headache has been the focus of many studies. The current study was designed to evaluate IgG and IgM antibodies to H. pylori in patients suffering from migraine headaches. ⋯ There was a significant difference in mean OD value of both antibodies to H. pylori amongst the case and control groups. As a result, active H. pylori infection is strongly related to the outbreak and severity of migraine headaches, and H. pylori treatment reduces migraine headaches significantly. Hopefully, the definite treatment and eradication of this infection can cure or reduce the severity and course of migraine headaches significantly if not totally.

Pulmonary embolism (PE) is the third most common cause of death in hospitalized patients. Diagnosis is often missed because of a non-homogeneous clinical picture. ⋯ During hospitalization, dyspnoea was exacerbated; a non-productive cough, chest pain and oliguria were observed. Pulmonary embolism was diagnosed, but because of the renal failure diagnosis was not confirmed by angio-CT.

Treating the elderly is often problematic, especially when congenital heart disease is diagnosed. The aim of this study is to present the case of a 72-year old woman with depression syndrome, paroxysmal atrial fibrillation and past cerebral stroke, in whom persistent ductus arteriosus Botalli was diagnosed. ⋯ After intermission of the therapy she was treated with dabigatran. The patient is still undergoing outpatient treatment and so far, no cerebrovascular episodes have been recorded.
