current status of treatment of pneumonia.proper treatment of pneumonia is dependent upon a correct diagnosis. pneumonia may be due to infectious agents, allergic phenomena, or chemical causes. treatment regimens are outlined for the various types of pneumonia--pneumococcal, staphylococcal, fungal, and pneumonia due to gram-negative and anaerobic gram-negative bacilli, to blastomyces dermatitidis, and to the parasite pneumocystis carinii. in discussing current concepts of treatment, several well-known methods are emphasized, as well as ...1975792
diagnosis and therapy of primary defects of immunity (author's transl).immunological responses are divided into those mediated by humoral antibody (b-cells) and those by cells (t-cells). both depend upon the activity of small lymphocytes which become thymus or bursa analogue dependent during embryonic development. primary immundeficiencies are therefor defects of lymphocytes attributed in most cases to gene defects. early diagnosis is the necessary prerequisit for possible treatment. tests for assessing the cellular immune status are: skin testes and in vitro tests ...19752800
neutrophil function in bone marrow transplant recipients.the neutrophil function of seven patients receiving allogeneic bone marrow transplantion was studied. five of the patients had been transplanted for aplastic anaemia and two for acute leukaemia. determinations were made of neutrophil phagocytosis, chemotaxis, random migration, and microbicidal activity for candida albicans and staphylococcus aureus. one patient showed a decreased ability to kill c. albicans at a time when she had active pneumonia due to pneumocystis carinii. the remainder of the ...197715582
arthritis rounds. pneumocystis carinii associated with polyarteritis and immunosuppressive therapy.pneumocystis carinii characteristically causes pneumonia in patients with immunodeficiency disorders. it occurs most often in patients with malignancy or renal transplants whose immune response has been suppressed by corticosteroids or cytotoxic agents. individuals with connective tissue disease who receive immunosuppressive drugs become susceptible to pneumocystis. the incidence of pneumocystis infection in connective tissue disease is low but may increase if immunosuppressive drugs are used mo ...197717412

false negative biopsy in pneumocystis carinii pneumonia.unlike most pneumonias, the diagnosis of pneumocystis carinii pneumonia is based solely on identifying organisms by stain, usually with methenamine-silver. because of technical problems involved with adequate staining, control samples usually are done concurrent with tissue specimens to be examined. lung containing fungi often is used as a control. we recently observed false-negative biopsy specimens in a case of p carinii pneumonia where the pneumocystis organism failed to stain with methenamin ...197984733
