[The variability of peak inspiratory flow (PIF) on valves imitating dry powder inhalers resistance during asthma and COPD exacerbations].

Introduction: Drugs used in asthma or COPD exacerbation are delivered to the lungs by inhalation. This is facilitated, among other factors, by the use of dry powder inhalers (DPIs). Lung deposition from DPI depends predominantly on peak inspiratory flow (PIF).

[Transient pancytopenia due to ticlopidine--a case report].

Transient pancytopenia as an adverse hematologic reaction due to ticlopidine. We present a case of transient pancytopenia due to ticlopidine in 66-year-old woman who was administrated with ticlopidine as a primary prevention of heart failure. The first sign was a skin rush which was followed by ticlopidine cessation.

[Blood and tissue eosinophilia in patient with angioedema caused by inhibitor of angiotensin converting enzyme (ACE)--case report and a view of literature].

A case of angioedema caused by enalapril, undiagnosed for 5 years was presented. Enhanced blood and tissue eosinophilia shown in nasal smear was observed. In addition increased activity of coagulation system was shown manifested by enhance of concentration of Hageman factor and cardiolipin antibodies IgM and IgA isotype.
