[Invasive aspergillosis (IA) in patients treated in the Institute of Tuberculosis and Chest Diseases in the years 1993-2005--diagnostic problems].

The aim of this study was to present the diagnostic problems in pts treated for invasive aspergillosis (IA) in the IIIrd Clinic of the Institute of Tuberculosis in the years 1993-2005. The material consisted of clinical documentation of 18 pts. 15 out of 18 pts (83,4%) died.

[Synantropic cockroaches (Blattella germanica L.) in hospital environment--microbiological hazard for patients and hospital infections risk assessment].

Objective: The aim of our study was to determine what a hazard for patients creates the presence of cockroaches in hospital environment.

Material And Methods: The probable hospital infections cases in 9 hospitals in Warsaw were found in database of the Country Hospital Morbidity Register for the year 2004 and correlation between such factors as: drug resistance of bacteria isolated from external part of cockroach's bodies, their ability to biofilm building, adherence, resistance to disinfectants, resistance of cockroaches to insecticides, infestation level vs. infections of several body systems was examined.

[Invasive aspergillosis in autopsy material of patients treated at the Institute of Tuberculosis and Chest Diseases during the years 1993-2000].

The aim of this paper is an analysis of clinical documentation and results of autopsy of 21 patients (pts) who died of invasive aspergillosis (IA) in the Institute of Tuberculosis and Chest Diseases in years 1993-2000 and the assessment of predisposing factors for IA. In 17 pts IA was the main and in other 4 only an accessory cause of death. All pts were treated with corticosteroids and/or cytostatic drugs--because of lung cancer (11 pts), cancer in other site (2 pts), haematologic disorders (2 pts), Wegener's granulomatosis (1 pt), polymyositis (1 pt), idiopathic pulmonary fibrosis (1 pt) and other diseases (3 pts).

[Microbial analysis of clinical material taken from patients at the Oncology Center, Maria Skłodowkda-Curie Institute in Warsaw in 1997].

An analysis was carried out of the microbiological investigations of clinical material samples obtained from the patients of two oncology centres belonging to the Warsaw Oncology Centre. Microorganisms cultured from urine, blood, catheters, smears of wounds and other materials were analysed. From 4839 clinical material samples from the Ursynów centre 1755 bacterial strains were isolated.

[Invasive pulmonary aspergillosis caused by Aspergillus ochraceus].

Invasive pulmonary aspergillosis (IPA) is a frequent complication in patients with severe neutropenia resulting from cytotoxic chemotherapy. In Europe, Aspergillus fumigatus is most common pathogen of IPA. In our case, IPA was recognised in 54 year old female suffering from acute lymphoblastic leukemia with pancytopenia.
