Imipenem/cilastatin sodium (IPM/CS) was administered to 55 patients with respiratory tract infections (RTI). A clinical evaluation of IPM/CS was carried out in 51 patients, 28 with pneumonia, 4 with pulmonary abscess, 1 with pyothorax, 6 with bronchitis, 9 with bronchiectasis, 1 with diffuse panbronchiolitis and 2 with RTI with chronic obstructive pulmonary disease, and the clinical efficacy rate was 78.4%. Causative organisms were isolated in 23 strains out of 20 patients, such as Staphylococcus aureus 4 strains, Staphylococcus epidermidis 1 strain, Streptococcus pneumoniae 1 strain, Branhamella catarrhalis 1 strain, Haemophilus influenzae 2 strains, Klebsiella pneumoniae 4 strains, Pseudomonas aeruginosa 6 strains, Pseudomonas sp. 1 strain, Acinetobacter calcoaceticus 1 strain, Acinetobacter sp. 1 strain and glucose non-fermentative Gram-negative rod 1 strain. An eradication rate of 70.6% was obtained. An overall eradication rate of main causative organisms in RTI including S. aureus, S. pneumoniae, H. influenzae and K. pneumoniae was 75.0%. Clinical adverse effects were observed in 5 patients, and these were eruption in 2, itching in 1, vomiting in 1 and drug fever in 1. Abnormalities in laboratory test results were observed in 8 patients. These disappeared or returned to normal values after completion or discontinuation of IPM/CS administration. IPM/CS appears to be a useful antibiotic for the treatment of RTI, especially severe infections.

The effect of an oral effervescent formulation combining 200 mg cimetidine and 1.8 g sodium citrate on gastric pH and volume were studied in patients undergoing caesarean section. Seventy-four patients undergoing elective (group 1) or emergency caesarean section (group 2) were included. Before entering the operating theater (5 to 60 min before intubation), they were given the tablet dissolved in 15 ml of water. Induction and maintenance of anaesthesia were carried out with conventional techniques. The patient's gastric content was aspirated just after endotracheal intubation, and before extubation. its pH and volume were measured at both times. Mean pH was similar in the two groups after intubation (6.07 +/- 1.13 in group 1; 5.52 +/- 1.14 in group 2) and before extubation (6.32 +/- 1.08 vs. 5.85 +/- 1.02 respectively). Gastric pH was therefore greater than 2.5 in all 74 patients at both times. Mean volumes of gastric content after intubation were greater in group 2 (32.7 +/- 23.9 ml vs. 21.6 +/- 15.8 ml; p less than 0.02). However, just before extubation, these were similar (15.0 +/- 15.4 ml in group 1, 20.1 +/- 14.9 ml in group 2). The percentage of patients in the 2 groups with gastric volumes greater than 25 ml at the time of intubation were not significantly different (29.7% vs. 45.9% respectively). No patient was at risk of developing pneumonitis in case of aspiration (gastric content pH less than 2.5 and volume greater than 25 ml), either during endotracheal intubation or extubation.(ABSTRACT TRUNCATED AT 250 WORDS)

Varicella (chickenpox) is sometimes associated with serious complications characterized bp changeable frequency in different ages. We describe a case of varicella with contemporary presence of several complications: serious impetigo , conjunctivitis, pneumonia, hepato-encephalic disease (probable Reye syndrome). This case is interesting because after adequate rehydration and normalization of electrolytes we registered a remarkable fall of plasmatic sodium and chloride as a result of hemodilution probably due to a syndrome of inappropriate secretion of antidiuretic hormone, confirmed by values of plasmatic and urinary osmolarity and of urinary electrolytes.

We report a retrospective study of 15 patients with prostate carcinoma and diffuse bone metastases treated with sodium 32P for palliation of pain at Downstate Medical Center and Kings County Hospital from 1973 to 1978. The response rates, duration of response, and toxicities are compared with those of other series of patients treated with 32P and with sequential hemibody irradiation. The response rates and duration of response are similar with both modalities ranging from 58 to 95% with a duration of 3.3 to 6 months with 32P and from 75 to 86% with a median duration of 5.5 months with hemibody irradiation. There are significant differences in the patterns of response and in the toxicities of the two treatment methods. Both methods cause significant bone marrow depression. Acute radiation syndrome, radiation pneumonitis, and alopecia are seen with sequential hemibody irradiation and not with 32P, but their incidence can be reduced by careful treatment planning. Hemibody irradiation can provide pain relief within 24 to 48 h, while 32P may produce an initial exacerbation of pain. Lower hemibody irradiation alone is less toxic than either upper hemibody irradiation or 32P treatment.

In a study on lung adenomas induced by the administration of a single intragastric dose of sodium thiocyanate, diethylnitrosamine, or its precursors to 15-day-old C57BLxC3H F1 mice the occurrence of crystalline inclusions in pulmonary parenchyma was noted. A correlation between crystalline deposits and number and type of adenomas seen between 46 and 110 weeks was observed. In 45/61 adenomas, eosinophilic cells containing inclusions were seen scattered in the pulmonary tissue, adjacent to tumor areas, in desquamated cells in the bronchioles, in the lumens of the submucosal bronchial glands, and within the alveoli. By contrast 7/85 mice without adenomas showed inclusions (4/7 mice had pneumonitis). The inclusions stained with bromophenol blue, were PAS positive diastase resistant and showed varying amounts of alpha-1-antitrypsin, IgG, and IgA by immunoperoxidase technique. Ultrastructure revealed membrane bound rods with a lattice pattern.

Amiodarone (ADR), a new antiarrhythmic drug for life-threatening cardiac arrhythmias, causes pneumonitis or lung fibrosis in a sizeable minority of patients. The cause of lung damage is not known. We have shown that infusion of 10 mg amiodarone into the inflow circuit of ventilated and perfused rabbit lungs causes immediate increase in pulmonary artery pressure (mean +/- SEM) (from 13.6 +/- 1.2 to 40.6 +/- 9.5 mm Hg, p less than 0.01) and pulmonary edema with marked increase in the pulmonary generation of thromboxane and leukotrienes C4 and/or D4. Albumin (2 g%) in the perfusate prevents any increase in lung perfusion pressure or edema formation. When lung perfusion pressure increase is blocked with the combined cyclooxygenase and lipoxygenase inhibitor enolicam sodium (CG5391B, 35 microM in perfusate), significant lung edema still occurs after amiodarone, indicating that amiodarone causes increased alveolar-capillary membrane permeability. Addition of catalase (100 U/ml) or superoxide dismutase and catalase (100 U/ml each) to perfusate fails to protect from amiodarone lung injury. Immediate infusion of amiodarone (10 mg) into lungs ventilated with room air (ADR + RA) causes an increase in lung weight gain from baseline (delta W) of 5.7 +/- 1.5 g/min. Compared with ADR + RA, ventilation of lungs with 4% O2 (delta W = 0.7 +/- 0.3 g/min, p less than 0.05), pretreatment of rabbits for 3 days with butylated hydroxyanisole (BHA, 100 mg/kg/day i.p., delta W = 0.05 +/- 0.02 g/min, p less than 0.01), pretreatment of rabbits for 3 days with vitamin E (Vit E, 300 U/day orally, delta W = 0.6 +/- 0.2 g/min, p less than 0.05), or addition of N-acetylcysteine to the lung perfusate (NAC, 5 mM, delta W = 0.1 +/- 0.08 g/min, p less than 0.01) all protect from lung edema formation after amiodarone. Amiodarone (100 mg) also caused a marked increase in luminol-enhanced lung chemiluminescence, lung production of superoxide anion (O2-), and tissue levels of lung glutathione disulfide. These results suggest that amiodarone causes lung injury by an oxidant mechanism.

Proline-rich protein (PRP) is a plasma protein associated with lipoproteins. In an attempt to clarify the biological significance of this protein, we isolated and characterized it and studied the biological role in plasma. PRP was isolated by immunosorber column chromatography and by gel filtration and ion-exchange chromatography. The molecular weight determined by gel filtration chromatography was 352,000, that is, about 5-times larger than the weight determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (73,800), indicating pentamer formation. About 10 or 11 isoproteins (pI 5.89-6.55) were observed by isoelectric focusing gel electrophoresis. PRP contained fucose, mannose, galactose, glucosamine and sialic acid accounting for 8.0% of the dry weight. PRP also had a hydrophilic property, as determined by charge shift electrophoresis. Levels of this protein in the human serum related to triacylglycerol-rich lipoproteins. The concentration of PRP correlated to the erythrocyte sedimentation rate (ESR), the C-reactive protein (CRP) and alpha 1- and alpha 2-globulin. Sera from patients with infection and inflammation showed significantly higher PRP levels than those noted in controls. Levels of PRP rose in parallel with ESR and CRP levels following acute myocardial infarction, and the maximal level was noted on the 7th postinfarction day. The PRP levels were elevated during the active phase of pneumonia, followed normalization. These data suggest that PRP is an acute phase reactant and may be important in the metabolism of triacylglycerol-rich lipoproteins.

A retrospective study was performed to review the clinical features and outcome of 39 episodes of pneumococcal meningitis in 36 adult patients over a 12-year period. Overall mortality was 33.3%. Only a few of the deaths were directly related to the central nervous system disease and most of them were due to cardiorespiratory failure. Univariate analysis showed that death was more likely to occur in patients with advanced age, an absence of neck stiffness, a high pulse rate, an associated pneumonia, internal complications, or a long duration of the disease (greater than 7 days) before treatment was started. Patients who died had a higher erythrocyte sedimentation rate and serum bilirubin level and a lower serum sodium level than those who survived. Discriminant analysis showed the development of internal complications to be the strongest predictive factor of a poor outcome of illness. Two other important predictors of a poor outcome were the absence of neck stiffness and associated pneumonia. The history of a skull fracture or head surgery was significantly correlated with a better than average prognosis. The incidence of sequelae in survivors at the time of discharge amounted to 72%. None of the clinical features were significantly correlated with the development of sequelae, except a higher cerebrospinal fluid protein content.

Passive protection of specific pathogen-free lambs against experimental pasteurellosis was achieved using antisera from conventionally reared sheep which were either convalescent from experimental pneumonia or inoculated with Pasteurella haemolytica A2 vaccines. The complete immune sera, or immunoglobulin-rich fractions prepared from them, when administered separately or together provided 94-100% protection of recipients compared to control lambs. Antibodies to P. haemolytica in donor sera were quantified by anti-sodium salicylate extract (SSE) and anti-lipopolysaccharide (LPS) ELISA, bactericidal assay, cytotoxin neutralization and indirect haemagglutination. The anti-SSE ELISA titres correlated best with protective efficacy and could be used to measure antibody in recipient lambs immediately before challenge. The degree of protection was unaffected by prior infection with parainfluenza virus Type 3, suggesting that such exposure did not enhance exudation of circulating immunoglobulin into the respiratory tract. It was concluded that systemic humoral immunity alone can prevent pasteurellosis.

Pneumocystis carinii is an opportunistic pathogen of man, carried as a commensal in healthy subjects. It frequently causes a fatal pneumonia in the immunosuppressed host. It is a major complication of HIV-1 infection in man (AIDS). Using surface radioiodination of rat-derived P. carinii trophozoites obtained from in vitro culture, a major surface glycoprotein (gp120) has been identified. The glycoprotein exhibits adherent behavior similar to that of the intact organism. Purification of gp120 by conventional methods was unsuccessful as the glycoprotein irreversibly bound to numerous column matrices. A combination of gel chromatography and hydroxyapatite chromatography in sodium dodecylsulfate was utilized to purify the glycoprotein. Some preliminary characterization of the glycoprotein is presented.
