Polychlorinated biphenyls (PCBs) are ubiquitous in the environment. Midway Atoll, located in the North Pacific Ocean, was occupied by the military during and after World War II. However, Midway Atoll has become a national wildlife refuge and home to many different seabirds today, including the black-footed albatross (Diomedea nigripes) (BFAL). The profiles and toxic equivalents (TEQ) of PCB con...

A 45-year-old man was seen in consultation for evaluation of a spiculated right-lower-lobe mass that enlarged over 1 year. The patient had suffered accidental instillation of activated charcoal into the right lung via nasogastric tube 2 years prior to this consultation, with resultant respiratory failure, pneumonia, and pneumothorax. Biopsy of the mass showed anthracosis and granulomatous infla...

The aim of this study was to determine the distribution of lung diseases in the autopsy subjects brought for medicolegal examination in the Transkei area. Two hundred histopathological slides were examined microscopically. Of them, 46 subjects (23%) showed some kind of pathology. There were four kinds of lesions observed: dust reticulation (anthracosis), necrotizing granulomatous inflammation, ...

A Mexican woman, aged 71 years, with life-long exposure to soot from a wood cook stove in a closed environment, who was treated for tuberculosis 4-years prior, presented with prominent mediastinal lymphadenopathy with anthracosis. Mediastinal lymphadenopathy is a common presentation of diverse granulomatous, malignant and infectious conditions like tuberculosis. Anthracotic pigment is found in ...

The circumstances in which pulmonary hypertension is found alone or in association with emphysema, mitral stenosis, or congenital cardiac shunts have been described already (Gilmour and Evans, 1946; Evans, 1951; Evans et al., 1957; Evans and Short, 1957 and 1958). This paper discusses pulmonary hypertension in relation to the less common clinical states that cause a rise in pulmonary arterial p...

Indoor air pollution appears to be a major environmental and public health hazard for large numbers of the underdeveloped world's population. A detailed environmental history is important for making diagnosis in most individuals from foreign rural settings with nonspecific respiratory symptoms. In this report, we describe an illustrative case of domestically acquired particulate lung disease (D...

Chest roentgenogram of a sixty-year-old male patient, revealed a tumoral mass in the right lung, that was later demonstrated by transbronchial biopsy, to be a bronchogenic adenocarcinoma. There was no tomographic evidence of distant metastasis, however, in order to assess the mediastinal involvement for staging of the tumor, biopsies from the regional lymph nodes were obtained. Microscopic exam...

We reported a case of complicated silicosis that occurred in a glass manufacturing plant worker who had presumably been exposed to low-concentration free silica for almost 20 years. To the best of our knowledge this report is the first in the Republic of Korea. The physician's first impression was cancer since the enlargement of neck and supraclavicuar lymph nodes had clearly progressed and met...
