T he patient was a 72-year-old man with a supenor mediastinal, paratracheal mass that was first noted on a chest x-ray film obtained 3 years earlier during a hospitalization after a tractor accident. Further evaluation was not undertaken at that time given the seriousness of the patient’s trauma. The patient survived his injuries and over the following 3 years noted progressive breathlessness w...

Case 1 was a 46-year-old man who developed neck pain in addition to pain and swelling in the limb joints in 1975. The patient was diagnosed with ankylosing spondylitis (AS) in 1983 based on detection of sacroiliitis on X-ray as well as a positive result for HLA B-27.

A PREVIOUS STUDY lo reported the effect on man of exposure to an atmosphere consisting primarily of oxygen at reduced total pressure (190 mm. Hg). Arterial desaturation was found in two of eight test subjects at the conclusion of 17 days, suggesting the possibility of atelectasis being present. This was not cordlrmed by either x-ray or vital capacity data. Atelectasis had been noted, however, a...

background: encephalitozoon cuniculi infects a wide range of homoeothermic animals, including man. complications due to this microsporidian have been reported only in immunocompromised patients. reports on e. cuniculi in immunocompetent humans are lacking, most probably, because it is not linked to any clinical manifestations in such hosts. the present work was carried out with the aim of study...

Wood–polymer composites (WPCs) were prepared from poplar wood (P. ussuriensis Komarov) in a two-step procedure. Maleic anhydride (MAN) was first dissolved in acetone and impregnated into wood; this was followed by a heat process; and then, glycidyl methacrylate (GMA) and styrene (St) were further impregnated into the MAN-treated wood, followed by a second thermal treatment. Finally, the novel W...
