[Zatorowosc plucna wysokiego ryzyka powiklana naglym zatrzymaniem krazenia i udarem mózgu - opis przypadku]. / High risk pulmonary embolism complicated with sudden cardiac arrest and stroke ­ a case report.

The pulmonary embolism is caused by the sudden occlusion or narrowing of the pulmonary artery or its branches through the emboli and it is the third cause of death due to cardiovascular diseases. This disease is characterized by multiple complications, among others, the sudden cardiac arrest or stroke. The success in treatment of pulmonary embolism depends on the early disease diagnosis and a valid therapeutic procedure. The aim of this paper is to discuss the diagnostic and therapeutic procedure in pulmonary embolism, based on the case report of 65-year-old patient with high risk pulmonary embolism complicated with sudden cardiac arrest and stroke. In this paper, the authors prove that proper pre-hospital diagnosis, rapid transport by emergency medical team to appropriate medical center, organization of an emergency department team, a cardiologist and the proper treatment significantly increases the chance of survival and return to full recovery of patients with pulmonary embolism at high risk.

[Fifty percent of pollinosis patients sensitive to birch pollen demonstrate bronchoconstriction during bronchial provocation test with the allergen]. / Polowa chorych na pylkowice, uczulonych na pylek brzozy, reaguje skurczem oskrzeli w trakcie oskrzelowego testu prowokacyjnego z alergenem.

UNLABELLED: Birch pollens are known as seasonal asthma precipitants. Our earlier studies evidenced a very high frequency of positive results bronchial allergen challenges in pollinosis patients sensitive to grass pollen. The aim of the study was to evaluate how often the bronchial challenge with birch pollen allergen causes bronchoconstriction. MATERIAL AND METHODS: Studies were performed outside of pollen season on 30 patients sensitive to birch pollen allergen. Before the allergen challenges bronchial provocation tests with methacholine were performed in all subjects. RESULTS: About 13% of examined group had bronchial hyperreactivity (PC20FEV1Mch < 8 mg/ml) and 50% demonstrated bronchoconstriction after birch pollen allergen inhalation. CONCLUSIONS: About 13 percent of patients sensitive to birch pollen demonstrated nonspecific hyperrectivity out of pollen season. Bronchial birch allergen challenge tests are positive in about half of birch sensitive patients with pollinosis.
