[Stomach neoplasm with pulmonary dissemination--diagnostic difficulties]. / Rak zoladka z przerzutami do pluc--trudnosci rozpoznawcze.

The case of nineteen years old patient with a milliary-like lesions in the lung due to gastric carcinoma is presented. Rapid progression and atypical course of the disease were a cause of difficulties in establishing a proper diagnosis.

[Occurrence of non-spore forming anaerobic bacteria in the upper airways of patients with chronic obstructive pulmonary disease]. / Wystepowanie nieprzetrwalnikujacych bakterii beztlenowych w górnych drogach oddechowych u chorych z przewlekla obturacyjna choroba pluc.

The aim of this study was to assess the occurrence of anaerobic non-sporeforming bacteria upper airways flora in the exacerbation of COPD. Sputum from 35 COPD patients was sent to the laboratory in sterile, filled with CO2 containers and cultured under anaerobic conditions. In all patients bacteriological tests were positive. The most common anaerobic bacteria were as follows: Peptostreptococcus - in 28 pts, Fusobacterium - in 27 pts, Bacteroides - in 26 pts and Prevotella in 24. Less common were: Propionibacterium, Actinomyces, Eubacterium, Porphyromonas and Peptococcus. The susceptibility to most common antimicrobial agents was evaluated. All anaerobic bacteria show a significant sensitivity to amoxicillin either with clavulanic acid or ampicillin with sulbactam. Gram-positive rods were resistant to metronidazole and tinidazole.

[Thoracoscopy]. / Wziernikowanie jamy oplucnej.

The purpose of the work is presentation of own experience in the use of thoracoscopy in patients with pathological pleural changes. In the years 1989-1991 in the Chair and Department of Pulmonology and Tuberculosis, Medical Academy in Gdansk, 20 thoracoscopies were performed with simultaneous taking of material for histopathological examination. In 15 patients from this group the diagnosis was made confirming the aetiology of pleural pathological changes. It should be stressed that in the group of patients with suspected malignancy, the diagnosis was confirmed in 100% of cases. Thoracoscopy is a useful diagnostic procedure during which aimed pleural biopsy may be performed.

[Rapid preliminary diagnosis of anaerobic bacterial infections. I. Natural fluorescence of pus, purulent fluids and dressing under UV radiation]. / Szybka, wstepna diagnostyka zakazen bakteriami beztlenowymi. I. Fluorescencja naturalna ropy, plynów ropnych i opatrunków pod wplywem promieniowania UV.

For evaluation of usefulness of natural fluorescence of clinical materials in UV radiation as rapid diagnostic method of infections with anaerobes, 405 samples of pus, bloody-purulent fluids, blood, wound secretions, dressings and other materials were investigated. Occurrence of red-brick UV fluorescence of clinical materials was compared with results of culture aimed at isolation of non-sporeforming anaerobes from "B. melaninogenicus group (P. melaninogenica, P. intermedia and P. saccharolytics). Significant correlation red-brick fluorescence of clinical materials resulting from UV irradiation with presence in these materials of anaerobes such as P. melaninogenica, P. intermedia and P. asaccharolytics was detected. Investigation of clinical materials with application of fluorescence in UV radiation lasts only 1-2 minutes and together with preparation and microscopical inspection which is Gram-stained--only 15-20 min. Positive results of this test may constitute a basis for rapid, preliminary identification of the etiologic factor and for direction of chemotherapy in the early period of infection.
