Pneumococcal polysaccharide was detected by counterimmunoelectrophoresis in the sputum of 20 of 26 (77%) adults with community-acquired pneumonia and a positive sputum culture for Streptococcus pneumoniae. The test was negative in 29 pneumonia patients with negative sputum culture for S. pneumoniae. Pneumococcal antigen was also detected in the sputum of six of nine adults with chronic bronchitis and a positive sputum culture, but was not detected in expectorated respiratory secretions of 22 pneumococcal carriers with colds. Pneumococcal antigen could also be detected in sputum by immunodiffusion; antigen titers varied from 1:2 to 1:256. These results strongly suggest that the detection of pneumococcal antigen in respiratory tract secretions indicates infection caused by S. pneumoniae.

1032 Interventions on geriatric patients beeing more than 70 years old between 1966 and 1975 demonstrate the significance of azotemia in the postoperativ stage of the disease appears as well as its dependence upon prehospital factors, type and localisation also on the extension and duration on the intervention in each single case. Since it is hardly possible to exert an influence on the preliminary stress due to the old age and on the dysfunction determined by involution of the parenchymatose organs important for the course of the postoperative stage, a particular emphasis should be laid upon the prophylactic aspekt to the purpose of an appropriate screening against vegetativ-visceral, renally effective shock reflexes (hepatorenal syndrome) and on the other, usually extra-renal factors (PH 203R, splanchnic block). Further possibilities: considerate elimination of pain and general anesthesia, purpuseful and quick operative technique, improvement of the apparatus and instruments, after-treatment specific for the given case so as one consisting of a prophylaxis against pneumonia through a rapid reactivation of the operated person. However, regardless to all the professional advance made in this field, the primary human approach to the aged patient and to his life expectancy should be made due allowance for.

The role of anaerobic and aerobic microorganisms in the genesis of pneumonia or lung abscess in patients with historical, clinical, and radiologic findings suggestive of aspiration was compared to their role in similar patients without these findings. Bacterial specimens were obtained by transtracheal aspiration or thoracentesis. Anaerobes were isolated in 100% of the patients who were aspiration-prone as contrasted with only 20% of those who were not. Isolation of a single species or no growth was more common in the nonaspiration group, whereas multiple isolates were more common in the aspiration group. Patients with lung abscesses were treated with penicillin and all of them responded clinically, despite occasional recovery from the culture specimen of penicillin-resistant organisms. This suggests that lung abscess may be the result of a synergistic bacterial infection.

During a 7 1/2 year period pneumococci were isolated from body fluids of 124 patients at the Radcliffe Infirmary, Oxford -72 with pneumonia, 26 with meningitis and 26 with other serious infections. Eighty-one (65%) of the patients were over 50, and 33 (27%) were over 70 years old. Of the 124 pneumococcal strains 104 (84%), including 23 (79%) of those from patients who died, belonged to types included in the vaccines successfully used in South Africa and in Papua New Guinea. The relative frequencies of types in the Oxford series and in a larger British series agreed closely with those found in a recent survey of 3644 bacteraemic pneumococcal infections in 10 American cities. Any polyvalent pneumococcal vaccine licensed for use in the United States is thus likely to be relevant to the situation in Britain.

Graft-versus-host disease, a complication of allogeneic bone-marrow transplantation, involves primarily the skin, liver and intestines, but may also be associated with pneumonia. To determine the relation of graft-versus-host disease with pneumonia, we evaluated the autopsies of 59 allogeneic and two autologous recipients and 74 control patients with various pulmonary diseases, who had not received a bone-marrow transplant. Lymphocytic bronchitis, characterized by lymphocyte-associated necrosis of the bronchial mucosa and often the submucosal glands, was present in 12 of 20 patients with Grade 2 or greater graft-versus-host disease but in only three of 39 with Grade 0 to 1 disease (P less than 0.0005). Onset of respiratory disease correlated with the time of onset of graft-versus-host disease. Patients with lymphocytic bronchitis had a higher incidence of bronchopneumonia and acute bronchitis of the lower respiratory tract. Lymphocytic bronchitis did not occur in the controls and appears to be a component of graft-versus-host disease that leads to bronchopneumonia, probably through destruction of the mucociliary apparatus.

Eight patients are presented who demonstrate many of the pulmonary complications seen in the prune-belly syndrome. The patients are divided into two major groups: Group I includes pulmonary hypoplasia; Group II includes lobar atelectasis and pneumonia. The etiology, pathogenesis, and radiographic features of these complications are discussed. Pulmonary complications become more important as renal dialysis and transplantation spare more of these patients from an early uremic death. Prompt recognition of the type and the extent of pulmonary disease in patients with the prune-belly syndrome may lead to increased survival.

Antibody response to pneumococcal type-specific polysaccharide was measured with enzyme-linked immunosorbent assay (ELISA). The test was shown to be up to 500 times more sensitive than indirect hemagglutination using chromic chloride-treated red blood cells. In 16/17 patients with pneumococcal pneumonia a significant antibody increase was seen as measured with ELISA. Only 6/23 patients with pneumonia caused by Mycoplasma pneumoniae gave a pneumococcal antibody rise and in those cases the increase was very slight. The authors consider ELISA a valuable contribution to the serological diagnosis of pneumococcal disease.

Pneumococci relatively insensitive to penicillin G were isolated from the sputum of two patients with pneumonia. One of the organisms was also relatively insensitive to ampicillin, cefamandole, and cephalothin and was resistant to tetracycline. Because penicillin-insensitive pneumococci are being reported with greater frequency, continued surveillance of pneumococcal sensitivity to penicillin is appropriate.

pH, pCO2, pO2 and where possible DAaO2 determinations were done before, immediately after and 30 minutes after chest physiotherapy in 4 groups (respiratory adaptation disturbance, pneumonia, hyaline membrane disease--controlled ventilation and RDS--nasal-CPAP) of mature and premature infants and in a group of healthy infants. The most striking alterations of the parameters investigated were found in infants treated with nasal-CPAP and controlled ventilation where especially a decrease of pH and increase of pCO2 was observed. After small increases of paO2 immediately after physiotherapy the paO2 values and concomitantly DAaO2 values 30 minutes after chest physiotherapy fell below the levels before physiotherapy. There was no significant change from pretreatment values in any group of infants. A physiotherapist experienced in the care of infants with respiratory diseases is most important for achieving satisfactory results.

Fifty-six patients with pneumonia were grouped according to degree of clinical certainty that the etiologic agent was Streptococcus pneumoniae. Of 14 patients with definite or probable pneumococcal pneumonia, 12 had pneumococcal antigens detected in sputum by counterimmunoelectrophoresis (CIE), 13 had a positive sputum culture, and 12 had a Gram-stained smear of sputum suggestive of the diagnosis. Of 9 patients with definite nonpneumococcal pneumonia, none had pneumococcal antigens detected by CIE, but one had pneumococci isolated from sputum culture, and one had a Gram stain of sputum suggestive of pneumococci. Of 34 control patients without pneumonia, five had a positive CIE, 11 had a positive culture, and 15 had a positive Gram stain. When used to differentiate pneumococcal from other types of pneumonia, CIE of sputum appears to be a sensitive and specific test. Among patients without pneumonia, however, CIE lacks specificity. Additionally, sputum Gram stain may correlate as well as CIE with pneumococcal pneumonia, but further substantiation of this observation is necessary.
