Hairy cells from eight patients with hairy cell leukemia were evaluated with both light and transmission electron microscopy for their capacity to phagocytose zymosan, latex, staphylococcus aureus, and pseudomonas aeruginosa. In two patients, there was no phagocytosis of any of these substances; cells from three patients phagocytosed only latex; two, all except pseudomonas; and one, all 4 substances. Hairy cells became relatively smooth while in culture with staphylococcus, but no surface changes were noted during incubation with the other substances. Of the eight patients studied, one died of pseudomonas pneumonia and sepsis; pseudomonas was the only substance which her hairy cells did not phagocytose. The one patient whose hairy cells phagocytosed all 4 test substances developed a disseminated Mycobacterium intracellulare infection; culture of his hairy cells with this atypical myocbacterium showed no phagocytosis. Hairy cells have different phagocytic capabilities from patient to patient, and the evaluation of these capabilities in vitro might provide early identification of potential infectious complications.

Ampicillin-sensitive or -resistant Staphylococcus aureus and Klebsiella strains were cultured in various nutrient media as prototypes of the agents of sepsis isolated in bacteriological routine analysis. In each case, 2 ml of defibrinated human blood containing 100 and 1000 cells, 8 gamma and 80 gamma ampicillin/1 ml blood respectively were added to 50 ml of nutrient medium. The following media were used. 1. casein soya-bean meal peptone broth (Oxoid), 2. tryptose-phosphate medium (Oxoid), 3. dextrose broth (Oxoid), 4. brain-heart-dextrose medium (Oxoid), 5. brain-heart infusion, autoclaved (Difco), 6. brain-heart infusion, after sterile filtration (Difco), 7. vacutainer culture bottles (BD) prepared medium, 8. micrognost blood culture bottles (Biotest) prepared medium. While the sensitive staphylococcus strain exhibited a slower growth than the sensitive Klebsiella strain in all nutrient media, the growth rate of the two resistant variants was approximately the same for an initial count of 100 cells per ml of blood. Among the resistant staphylococci the higher initial count of the inoculum resulted in an improved growth. After addition of 8 gamma or 80 gamma ampicillin/1 ml blood the sensitive staphylococcus strain did not show any grwoth irrespective of the inoculated number of cells while the sensitive Klebsiella strain multiplied irrespective of the initial number of cells. After 24 hours the resistant staphylococci and Klebsiella strains of which 1000 cells each had been used for inoculation exhibited growth in almost all media used.

Cancer patients show an immune deficit whose beginnings are influenced to one extent or another, by two factors: the cancer itself, and the antimitotic-immunosuppressive treatment to which the patient is subjected. The immune deficit will have repercussions in the anti-infectious defense that these patients show: --Greater number of infections. --Greater severity of infections. --Tendency towards generalization and showing of septicemic states. The problem is most serious in hematological tumors (leukemia, lymphosarcoma) where the primary cause of death is infection. During the period of activity of the disease, and also in relation to the antimitotic treatment, the PMN will decrease in absolute count and will function poorly. The consequence will be a high frequency of bacterial infections, sepsis, pneumonia, skin infections, etc., predominantly caused by gram-negative germs and staphylococcus (any germ considered not to be "very virulent" can be found); and it will result in a high mortality rate. When these children are in remission or have solid tumors, the problem is not so acute, and bears more relation to antimitotic treatment and other extraneous factors (hospitalization, catheters, antibiotics, gastrointestinal ulcers...). Patients most frequently show localized bacterial, viral and protozoon infections (varicella, zooster, herpes simplex, cytomegalia, pneumocystis) because of the predominance of cellular immunity deficit.

Antistaphylococcal properties of the new lactic acid mixture propionic acidophilic milk (PAM) against the microbe isolated from feces of children suffering from staphylococcal sepsis were comparatively studied by the dilution and diffusion methods. PAM was found to have more pronounced antimicrobial properties against pathogenic staphylococcus than acidophilic milk and kefir. It is recommended to include PAM into the diet of children with intestinal dysbacteriosis.

Report on a 9-year-old boy with infected solitary cyst of the kidney on the left, resulting from this chronic relapsing sepsis with abscess of the spleen, perforation of the abscess into the left subphrenium, subphrenical abscess, basic empyema of the pleura on the left, purulent system of the fistulae in the left upper retroperitoneum. Causative organism: staphylococcus aureus. After 6 successless attempts to command the process from the flank side section, the transperitoneal radical operation with extirpation of the spleen, resection of the cyst and removal of the left upper retroperitoneum was carried out. After transient improvement acute relapse of the sepsis after 6 months with subcutaneous abscesses and empyema of the ankle joint on the left. Causative organism again staphylococcus aureus. Under repeated surgical, antibiotical and general treatment rapid and final disappearing of the sepsis. Since 3 1/2 years free from recidivation.

Autopsies of 252 cases of acute leukosis in children dying of sepsis were examined. Except 2, all the children had been in the state of exacerbation of the leukemic process and received current intensive therapy. Sepsis was the immediate cause of death in 68 (26.9%) cases. Most prevalent were such forms of sepsis as sepsis with embolic foci of necrosis in organs (44 cases), septicemia (18), septicopyemia (6). In 40 cases considerable leukemic infiltration of the bone marrow and internal organs, in 18 cases moderate and in 10 poor was observed. The criterian of sepsis in children with acute leukosis is the presence of embolic foci of necrosis, less frequently of metastatic abscesses. All the other signs may be associated both with leukemic and septic processes. The causative agent of sepsis in the majority of cases was hemolytic coagulaso-positive staphylococcus.

Information from 50 infants with neonatal septicemia from the Louisville General Hospital during an eight-year period (1964-1972) is presented. Twenty-five infants had gram-positive and the other 25 had gram-negative organisms. E. coli (13 cases), staphylococcus (10 cases), and hemolytic Streptococcus non-Group A (7 cases) were the mustcommon causative microorganisms. Only one of the 25 infants with gram-positive sepsis died; three with gram-negative sepsis died. Listeria monocytogenes was demonstrated in three infants; all had meningitis with no mortality. Early diagnosis, prompt intensive antibacterial therapy, and a high index of suspicion are most helpful for reducing the morbidity and mortality.

A study was made of some nonspecific immunity indices in staphylococcus sepsis and gastroenterocolitis during the infectious process in young children. Results of these investigations pointed to the depression of bactericidal and lysozyme activity of the blood serum and of the immunoadherence reaction at the acute period of the disease, and to some increase at the phase of recovery. There was also found an elevation of the phagocytic activity (of the phagocytolysis percentage) at the acute phase of the staphylococcus sepsis and gastroenterocolitis Antistaphylococcus gamma-globulin produced a positive effect on the lysozyme and bactericidal activity of the blood sera and promoted an increase of the blood phagocytic activity in the sick children.

Analysis of section material was carried out covering the period 1943-1975. It was established that proportion of septic diseases in the general structure of children's mortality in the recent years was stabilized at rather high levels (1973-1975--17.1%). Fatal outcomes were most often among infants at the early period of life in whom sepsis developed against the background of premorbid factors including prematurity, malformations, pathologic labour, mother's diseases, etc. The course of sepsis was particularly severe in infants with congenital immunodeficient states. The main pathogene of sepsis at present is staphylococcus. During the period under study, correlation and morphology of various forms of sepsis varied depending upon the pathogene and therapy applied. Since 1968 and up to new the most common form of sepsis has been that morphologically identical to sepsis observed in 1943-1947, i.e. before the wide application of antibiotics.

Burn wound sepsis is still a common cause of death in burn injuries. Eighty percent of this infection is with colonisation from the patient and twenty percent as a result of cross infection. Most of the mortality is due to virulent cross infection. Pseudomonas has almost disappeared and multiple resistant staphylococcus aureus is the main pathogen today. It can cause loss of skin grafts and septicaemia, particularly due to colonisation of intravenous lines. The risk increases with the time since the burn injury. Early excision and grafting is important. With a large burn it is not possible to do this in one session and so the risk is increased with a compromised patient. Maintenance of a good diet and vitamin supplements is important, preferably orally or through a naso-gastric tube. Parenteral nutrition increases the risk of infection. Clinical infection is combated by good cleaning procedures, preferably with chlorhexidine solution and the application of a good topical agent such as Silvazine. The presence of bacteria in the wound must be monitored. Strict barrier nursing and personal hygiene, particularly hand washing, are the mainstay of cross infection prevention. Antibiotics may be required, monitored by blood cultures. Documenting MRSA is a good way to monitor the unit's infection prevention programme. The main preventive measures are early referral, early excision and grafting, good nutritional support, good topical agents and barrier nursing.
