Track counting and the blots.

Track detectors are very useful devices for alpha particle dosimetry. Alpha particle tracks are registered on the detector's surface. The registered track density is proportional to the dose. When the dose is low the greatest effect on the total error of dose assessment has a Poisson distribution (random error). When the dose is high, the greatest contribution to the total error is the effect of track overlapping (systemic error). This paper describes how to solve the problem of overlapping tracks when a computer aided image analyser is used. The formulae presented in this paper were proven in the international calibration programme run by NRPB and EU.

Calibration↗

Film badges for personal dosimetry of roentgen radiation.

The paper describes the calibration procedure for and data obtained from routine X-ray dosimetry service in Poland. In 1998 the number of readouts amounted to 152,000. The dosimetry concerned 31,281 workers in 3,113 enterprises. The annual collective dose was assessed to be 16.7 man.Sv. The analysis of the calibration quality is discussed as well. Only 2.9% of all points lay outside the quality curve while the number of the acceptable outliers was 5%.

[Cooperation between pharmacists of Gdańsk and Wielkopolska region in the XX century].

The University of Poznań, with its Pharmaceutical Department was established after the First World War. Many of the pharmacists educated in Poznań were employed in the Pomorze Gdańskie region. This article describes the activities of these pharmacists in the years 1920-1939 and during the Second World War. The article also discusses the assistance of the University of Poznań in the organization of the Pharmaceutical Faculty of the Medical University of Gdańsk and of pharmacy in the Pomorze Gdańskie region. Those pharmacists who came back to Poznań after years spent at the Baltic seaside and those who studied in Gdańsk and were then employed in Poznań are also mentioned in the article.

Radium and radon in natural underground water supply in the region of Lódź, Poland.

The region of Lódź, located in the central part of Poland, is very specific with respect to water supply coverage. In this densly populated and extensively industrialised region there is a lack of natural reservoirs of surface water in the nearest vicinity of Lódź. Therefore, over 50% of water for public and domestic use is provided from underground water intakes. It is well known from the literature that in underground water may occur radionuclides in the uranium and thorium decay series. Underground water intakes in Lódź used for public water supplies have been surveyed for the presence of radium-226 and radon-222 since the earlier studies of quality standards of the gross alpha and gross beta activity pointed to their possible excessive values. The surveillance was based on the guidelines set by the World Health Organisation (WHO). The measurements of radium-226 activity showed its different concentrations depending on the age of the water-bearing level. These concentrations fell within the range of < 10 divided by 50 Bqm-3. Measurements of radon yielded similar results and its highest concentrations were found in the Lower cretaceous and Jurassic formations. Radon concentrations ranged from 200 to 11,400 Bqm-3. A maximum annual dose taken into the body in the population drinking this water may account for 0.85 microSv which is lower than the limit recommended by WHO.

[Pneumocystis carinii infections in patients with neoplasms and AIDS--clinical-pathologic changes in the lungs].

Pneumocystis carinii (PC) has been documented as a cause of pneumonia in a broad range of immunocompromised patients. The presentation of disease will very based on the underlying predisposing condition but a confirmation depends upon the identification of organisms in a bronchial aspiration or lung biopsy specimen. This retrospective study based on autopsies of 15 patients (pts) with AIDS and 12 non AIDS pts with neoplastic diseases. Pneumocystis carinii pneumonia (PCP) was confirmed by histologic examination. The clinico-pathological analysis emphasizes a spectrum of morphologic variation of the disease in relation to the clinical course of a principal disease. A distinction was made between the microscopical diagnosis of PC infection in AIDS and non AIDS pts; the burden of organisms in infected AIDS pts appeared greater than that of neoplastic diseases (mostly with small cell lung carcinoma). Nonspecific features of diffuse alveolar damage associated with PC organisms were identified in 67% of non AIDS pts and 13% of AIDS pts. Various degree of interstitial fibrosis was more prominent in AIDS pts (67%) than in non AIDS pts. The high frequency of atypical changes in lung might be the result of various chemotherapeutic agents used in managing these pts or repeated pulmonary infections.

[Mediastinal abscesses and empyema of the pleural cavity after iatrogenic fracture of the sternum].

A case report presents fracture of sternum during the resuscitation and in continuity iatrogenic hematoma and afterwards abscessus of mediastinum, and empyema the both of pleura cavities. Fracture of thorax wall is rather often event, but in the most, it has not adverse effects. This case refers to 68 years old patient, who had one of the most serious complications: abscessus of mediastinum, empyema of left and right pleura cavities with perforation outside the anterior wall of thorax. He was treated in General Hospital Biała Podlaska, Department of Surgery with good results and was extracted home as well-being patient after 35 days spent in hospital the second hospitalisation.

AIDS pathology: infections and neoplasms in 55 fatal AIDS cases. A postmortem study.

The study evaluated the incidence of infections and neoplasms in 55 out of 104 patients with AIDS who died in Poland from January 1986 to April 1994 (the estimated autopsy rate-52.8%). Histopathological examination revealed 103 infections and 11 neoplasms. In 40 persons (73%) either multiple infections or a neoplasm and an infection were diagnosed. Cytomegalovirus infection was most common. (65.5% of cases) followed by Pneumocystis carinii (24% of cases). These infections were the leading cause of death in 20% and 16% of cases, respectively. The results of this study showed a significantly lower incidence of Pneumocystis carinii, Kaposi's sarcoma and non-Hodgkin's lymphoma in comparison with the results of similar studies in countries with a large number of AIDS cases.

[Are lung choriocarcinoma and giant cell carcinoma producing chorionic gonadotropins just variants of the same neoplasm?].

An article presents two cases of choriocarcinoma lung metastases. One case revealed the primary mediastinal choriocarcinoma and the second one had unknown primary localisation of the tumor, which could be suggestive of a spontaneously regressed primary gonadal choriocarcinoma. Authors discuss the clinico-pathological aspects of extragonadal choriocarcinomas, theories of their histogenesis and the morphological similarities to anaplastic giant cell lung carcinoma.

[A case of bronchial carcinoid diagnosed after 21 years of recurrent lung infections].

A case of 59 year old woman with a 21 year history of recurrent pneumonias of the upper left lobe is presented. When she at last agreed for the diagnosis her chest X-rays revealed atelectasis and cirrhosis with bronchiectases of the left lung. Tumor of the left main bronchus and severe inflammation of the surrounding mucosa with purulent secretion were found during bronchofiberoscopy. The patient underwent left pneumonectomy. Histological examination of the specimen revealed presence of carcinoid in the main left bronchus without involvement of the regional lymphnodes, with signs of irreversible damage of other bronchi and pulmonary tissue. The very long period of observation since the first symptoms, no metastases in the bronchopulmonary lymphonodes and no distant metastases indicate the low-grade malignancy of the carcinoid in the presented case.

[Pulmonary arteriovenous fistulas].

Pulmonary arteriovenous fistulas are rare congenital malformations associated in 40% of cases with Osler-Weber-Rendu disease. PAF acquired in connection with the chest trauma, surgery and some inflammatory or neoplastic lung diseases were also described. In the Institute of Tuberculosis and Chest Diseases we have observed 11 cases of congenital PAF in 4000 resected lungs during the last years. In this report we described one more case with PAF. A 40 years old man was admitted to the Institute of Tuberculosis and Chest Diseases with hemoptysis. History and physical examination was unremarkable. Chest roentgenogram revealed a right upper lobe infiltrate. Tuberculosis or cancer was suspected and during the diagnostic procedures antituberculous drugs were given. After 3 weeks of treatment hemoptysis increased and chest roentgenogram revealed progression of the infiltrate in the right upper lobe and new lesions in the middle lobe. According to the character of X-ray progression which night be characteristic of active bleeding, a possibility of arteriovenous fistulas could not be excluded. As life threatening haemorrhage persisted right upper lobectomy without angiography was done. In the resected lobe arteriovenous fistulas were found. Angiography after operation was proposed but was refused by the patient. He is now well and symptoms free 5 months.

[Multi-organ failure syndrome. Clinical picture: report of 2 cases].

Two cases of MOFS (multi-organ-failure-syndrome) are presented. Pulmonary embolism was an initial presentation in one case, acute pneumonia in the other. In both cases intensive supportive treatment including mechanical ventilation was instituted because of acute respiratory failure. Sequential dysfunction and/or failure of other organs were observed. Both patients died despite 3 and 7 weeks of intensive treatment, respectively. In both cases MOFS was confirmed by autopsy.

[Difficulties in diagnosing tuberculous pericarditis].

Malignancy was diagnosed cytologically in a 62 year old female with exudative pericarditis. Despite extensive diagnostical procedures the primary source of the neoplasm could not be defined. After 18 months the patient died. Autopsy disclosed tuberculous pericarditis. The authors discussed the differential diagnosis between malignant and tuberculous pericarditis and the reasons for this diagnostical error.

[A device for measuring body posture during work].

The study was aimed at designing, performing and testing the tool enabling observation of the duration of the trunk inclination under the fibular plane and specific angles in professional work. Admittedly, the most ethiopathogenetic factor of an algesic syndrome in the lower part of the spine is the load resulting mainly from long-lasting trunk anteversion. The tool consists of a gravitating inclination sensor which switches on, with the programmed inclination angle, the quartz time meter. This tool is fastened to the examined patient by webbings to the level of the lumbar spine in the axillary left middle line. The results obtained due to this tool reflect the duration of trunk inclination under different angles at work in different workstations. It was found that the observations made due to that tool, when its inclination sensor is set at 10 degrees, 20 degrees and 30 degrees (forward), should be sufficient to indicate the workstations with static load of the lower part of the spine due to long-lasting trunk anteversion. The simplicity of the studies performed by means of that tool, as well as the fact that those studies are convenient (both for the physicians and patients) indicate the advisability of an extensive use of that tool (also in improved versions) in ergonomic practice.
