The effect of inhaled ammonium sulfate on benzo[a]pyrene carcinogenesis in the lungs of Syrian golden hamsters was studied. Exposure to ammonium sulfate at an airborne concentration 20 times average United States ambient levels resulted in a significant depression (p less than 0.05) of benzo[a]pyrene carcinogenesis in the first 6 mo of the study. However, at 2 yr, the termination of the study, there were no differences in cancer incidence between groups receiving benzo[a]pyrene and benzo[a]pyrene plus ammonium sulfate. In addition, at the concentration studied, inhaled ammonium sulfate did not significantly increase the incidence or severity of pneumonitis or pulmonary fibrosis in the hamster. However, this inhalation did increase the incidence of emphysema but not the severity. The decreased incidence of cancer during the first 6 mo of this study in animals receiving both benzo[a]pyrene and ammonium sulfate suggests that interaction between sulfate and benzo[a]pyrene does occur, but is insufficient to afford long-term protection against the development of cancer. No enhancement of carcinogenesis by benzo[a]pyrene occurs in the presence of inhaled sulfate.

The content of T and B lymphocytes, IgA, IgM and IgG as well as blood serum acid phosphatase (AP) activity were examined in 55 patients with purulent destructive complications of acute pneumonia. The patients were distributed into 2 groups depending on the disease gravity. The patients with a grave disease showed the depression of T and B immunity systems, marked deficiency of serum IgA, IgM and IgG. The percentage and absolute number of O cells was increased according to the disease gravity. In second group patients with a less graver disease, the reduction in the analogous immunity indicators was statistically insignificant. The disease ran the gravest course (with the development of pulmonary and extrapulmonary complications) in subjects with chronic alcoholism. The level of AP was the highest in disseminated destructive process and in diseases complicated by pleural empyema. During the convalescence, the AP activity descended, however it remained higher than normal in the presence of residual dry destructive cavities.

Epidural morphine infusion is an effective and relatively safe route for postoperative analgesia. Lanz , Theiss , Reiss , and Sommer performed research supporting the use of epidural morphine. Following lumbar epidural anesthesia for orthopedic operations, 174 patients underwent the following study. At the end of surgery under double-blind conditions, 57 patients in group 1 received 0.1 mg/kg of morphine in 15 ml of normal saline epidurally and normal saline 0.01 ml/kg intramuscularly. Patients in group 2 (57 patients) received intramuscular morphine 0.1 mg/kg and normal saline 15 ml epidurally. Patients in group 3 (60 patients) received normal saline 15 ml epidurally and normal saline 0.01 ml/kg intramuscularly. Postoperative pain was less frequent, of shorter duration, and less severe following epidural morphine (group 1). Sympathetic block was only partial; patients still noticed pressure due to a dressing or cast. There was no motor blockade and active mobilization occurred earlier. Following epidural morphine, alertness was heightened, patients were more cooperative, and respiratory depression and postoperative pneumonia were less than after systemic administration of narcotics.(ABSTRACT TRUNCATED AT 250 WORDS)

Peripheral blood lymphocyte cell surface markers were studied in 146 patients with various forms of acute infection using B cell identification with antisurface immunoglobulin and T cell subset enumeration with hybridoma T cell subpopulation reagents. Significant depression was recorded in total numbers of T cells and T cell helper-inducer and suppressor-cytotoxic subsets in pneumonia, acute pyelonephritis, and severe generalized sepsis. In addition, proportions of T cells being the OKT4 helper-inducer phenotype were reduced only in patients over the age of 60 with pneumonia or sepsis. Patients with severe infection frequently had multiple T cell phenotypic surface marker abnormalities. In some instances, when depressions of total T cell numbers as well as respective helper-inducer or suppressor-cytotoxic T cells were noted in the face of generalized sepsis, lack of improvement in these abnormalities during the course of treatment was associated with rapid clinical deterioration and death. On the contrary, in patients with a successful response to appropriate therapy, initial depressions of total T cell numbers and subsets improved progressively with clinical resolution of sepsis and illness.

The authors report on a female patient with bipolar affective disorder who presented with marked eosinophilia in conjunction with pneumonia five days after a medication change from amitriptyline to desipramine (for intolerable dry mouth). She improved with discontinuance of medications and supportive management, and her eosinophilia normalized. Reinstitution of desipramine was followed by prompt appearance of asymptomatic eosinophilia, which resolved with discontinuation of desipramine. A subsequent depression managed with amitriptyline was followed by no abnormal white blood count findings. Eosinophilia is occasionally encountered in imipramine or desipramine therapy and, although usually asymptomatic, appears to be manageable by switching to amitriptyline or nortriptyline.

The clinical course in an unselected group of 1125 consecutively hospitalised self-poisonings was studied during 1 year in Oslo. Mortality was 0.5%, but only 0.3% in those admitted without cardiac and respiratory arrest. Mortality among those in grade IV coma was 4.2%. The deepest comas (grade III or IV) occurred in 25.1% of the admissions with a mean duration of the coma of 5.8 h (range 1-80). Complications occurred in 21.7% of the admissions and 6.9% suffered more than one complication of which the most frequent were respiratory depression (13.5%), hypotension (5.3%), pneumonia (4.4%), and hypothermia (1.6%). The complication rate was highest in poisonings with opiates (60.7%), meprobamate (37.5%) and antihistamines (30.0%). Arrhythmias and respiratory depression were closely associated with poisonings with antidepressants and opiates, respectively. Owing to frequent polydrug overdoses it was difficult to associate other complications with other main toxic agents. Administration of antidotes (20.6%), cuffed intubation (4.4%) and forced alkaline diuresis (3.4%) were the most frequent special therapeutic measures taken. The change in pattern of self-poisonings in Oslo focuses on antidote therapy and intensive care, especially outside hospital, but limits the need for haemodialysis and haemoperfusion which were performed in only 1.0% of the admissions.

In 23 patients with Mycoplasma pneumoniae (MP) infection (13 with pneumonia and 10 with an acute febrile, non-bacterial disorder of the central nervous system (CNS)) and in 26 healthy control persons, thymidine incorporation of blood lymphocytes stimulates stimulated in vitro by killed MP was studied. The lymphocyte response to MP was significantly higher in the pneumonia patients than in the controls. In the patients with an acute disorder of the CNS, lymphocyte responses to MP tended to be low or normal in lack of pleocytosis in the spinal fluid, but were predominantly high when either pleocytosis or a pulmonary infiltrate was present. Lymphocyte responses to the mitogens PHA, PWM and Con-A were normal in all groups. The lack of increased responses to MP antigen in some of the neurological patients, despite a current MP infection, may reflect an antigen-specific depression or a lack of specific sensitization of their lymphocytes.

Rhesus monkey fetuses of either immune or nonimmune dams were inoculated in utero with Adenovirus SV-20 (AdSV-20), a virus capable of inducing fetal pneumonia, and studied immunologically at various intervals. AdSV-20 infection at 90-100 days gestational age resulted in absolute lymphopenia in a few fetuses, reduced numbers of peripheral blood lymphocytes (PBL) which formed rosettes with sheep erythrocytes (ERL) and reduced complement-receptor lymphocytes (CRL) in a majority, while Fc fragment-receptor lymphocytes (FcRL) were occasionally increased. There was a tendency for depression of ERL and CRL early in infection of 120-130-day fetuses, followed by stimulation of these populations and FcRL in later phases. Maternal immunity did not protect against these effects of AdSV-20 infection in fetuses. Immune and nonimmune dams were spared adverse clinical effects and had no changes in lymphoid cell populations following inoculation of their fetuses. Despite precocious production of circulating IgM, fetuses of nonimmune dams had little or no demonstrable anti-AdSV-20 serum neutralizing (SN) antibody, indicating that the ability to develop an effective immune response was suppressed or had not been acquired at the gestational ages studied. Nonimmune dams displayed little evidence of seroconversion following inoculation of their fetuses with AdSV-20, except in those dams whose fetuses died in utero, whereby there was a significant antibody response. SN antibody titers of immune dams were not boostered substantially subsequent to inoculation of their fetuses, and fetal SN titers were lower than maternal titers, suggesting absence of an active fetal antibody response in this group also. Direct inoculation of AdSV-20 into 90-130-day rhesus monkey fetuses provided a model system for immunologic study of fetal infection, probably involving complex fetal-maternal interactions, in a situation where the infected, viable fetus and its dam appeared to be microbiologically isolated from one another.

Little is known about prognostic factors that determine outcomes after in-hospital cardiopulmonary resuscitation. We studied prospectively 294 consecutive patients who were resuscitated in a university teaching hospital. Forty-one patients (14 per cent) were discharged from the hospital; three quarters of them were still alive six months later. A multivariate analysis revealed that pneumonia, hypotension, renal failure, cancer, and a homebound life style before hospitalization were significantly associated with in-hospital mortality (P less than 0.05). None of the 58 patients with pneumonia and none of the 179 in whom resuscitation took longer than 30 minutes survived to be discharged. On the other hand, fully 42 per cent of the patients who survived for 24 hours after resuscitation left the hospital. At the time of discharge from the hospital and again six months later, 93 per cent of the survivors were mentally intact. Although depression was generally present at the time of discharge, it tended to resolve subsequently. However, all patients reported some decrease in functional capacity, often attributed to fear. This persisted at six months after discharge. Age alone did not appear to influence the prognosis for survival after cardiopulmonary resuscitation or the adjustment to chronic illness after discharge from the hospital.

119 children with recurrent respiratory infections were investigated for immunocompetence. They were divided into two groups. The first, group A, comprised children who had had predominantly upper respiratory infections. Group B comprised those who had had repeated pneumonia in addition. The groups were comparable for gender and age (mean 4.2 years). All the children had reduced neutrophil chemotaxis, reduced neutrophil fungicidal capacity, and perhaps reduced T-cell percentages. Group B children had, in addition to the above, decreased neutrophil bactericidal capacity and a more marked depression of neutrophil chemotaxis. In both groups, some children had reduced immunoglobulin concentrations while others had either normal or increased concentrations. Serum complement, neutrophil iodination, and mitogen-induced lymphocyte transformation were comparable with adult controls in both groups.
