The application in purulent peritonitis of a novel surgical lavaging agent with unique properties is reported. Taurolin is a non-toxic formaldehyde-transmitter with a Thiadiazine structure exhibiting a twofold action in gram-negative sepsis owing to its bactericidal potency and its ability to denature endotoxins in vivo. The present study reports the surgical treatment of 62 patients with appendicitis and peritonitis of varying genesis, using 0.5% Taurolin as lavaging and 2% Taurolin as instillation agents. After 5 days 22 out of 25 patients with purulent peritonitis were void of intraperitoneal bacteria. To date no significant adverse drug reactions were observed.

Use of heat sterilization for dialysis reprocessing offers significant advantages over chemical germicides. Polysulfone dialyzers (Fresenius 60M or 80M) can be sterilized by heating to 105 degrees C for 20 hr, thus permitting clinical trials of this method. One hundred eighty patients received 9,000 treatments. Pyrogenic reactions, sepsis, and subjective symptoms have not occurred. In vitro clearances (Qb 500 ml/min, Qd 800 ml/min) at baseline and after 2-8 uses did not differ (340 +/- 29 vs. 352 +/- 4 ml/min, respectively). KoA determined in vivo did not decrease (baseline 709 +/- 131 vs. 7th use 632 +/- 50 ml/min). Kt/V for urea was not different in 18 patients treated with heat sterilized dialyzers over 6 months when compared with a baseline period with formaldehyde sterilized dialyzers (1.37 +/- 0.12 vs. 1.32 +/- 0.11 at similar time and blood flows). Mean use number was 7.4 (dialyzers limited to 11 uses). Of discarded dialyzers, 44% failed a bedside integrity test (blood side pressurized at > 400 mmHg for 1 min), 36% failed automated fiber bundle or pressure holding tests, 8% had a blood leak, and 12% reached 11 uses. Clinical blood leaks occur in < 0.5% of treatments. Heat sterilization is a safe and effective method of dialysis reprocessing, but quality control of the process is essential. Based on initial clinical experience, heat sterilization of dialyzers for reuse is a promising alternative to chemical disinfection.

To determine trends in a variety of dialysis-associated diseases and practices, the Centers for Disease Control surveyed 1,867 chronic hemodialysis centers in the United States in 1989 in conjunction with the annual facility survey performed by the Health Care Financing Administration. The response rate to a mailed questionnaire was 92%. These 1,726 centers represented 122,734 patients and 32,486 staff members. The following results were found. 1) During the last 14 years, the incidence of hepatitis B virus (HBV) infection decreased from 3.0 to 0.1% among patients, and from 2.6 to 0.1% among staff members. Over the same time, the prevalence of hepatitis B surface antigen (HBsAg) positivity declined from 7.8 to 1.4% among patients and from 0.9 to 0.3% among staff members. Hepatitis B vaccine was given by 92% of the centers. By the end of 1989, 19% of susceptible patients and 55% of susceptible staff members had received all three doses of hepatitis B vaccine. From 1982 to 1989, as a result of receiving vaccine, the prevalence of antibody to HBsAg (anti-HBs) increased from 12 to 19% among patients and from 18 to 54% among staff. The incidence of non-A, non-B hepatitis in 1989 was reported to be 0.7% among patients and 0.1% among staff members. 2) Twenty-two percent of the centers reported pyrogenic reactions in the absence of septicemia among their patients, and 51% reported septicemia. 3) The reported incidence of dialysis dementia among hemodialysis patients was 0.2%, with a case fatality rate of 23%. 4) In 1989, 68% of centers reported that they reused disposable dialyzers; these centers treated 73% of the dialysis patient population. Among centers that reused disposable dialyzers, the average number of reuses ranged from 1 to 50 (mean, 12) and the maximum number of times a disposable dialyzer was ever reused ranged from 3 to 150 (mean, 28). Chemical germicides used for reprocessing dialyzers included formaldehyde, Renalin (a peracetic acid-hydrogen peroxide-based germicide), and glutaraldehyde-based germicides. Reuse of disposable dialyzers was not associated with any increased risk of acquiring HBV infection among either patients or staff. However, pyrogenic reactions occurring in clusters were reported more frequently in centers that reused conventional dialyzer membranes compared with centers that did not. This increased risk was associated only with centers that used Renalin or glutaraldehyde for reprocessing (not formaldehyde) and occurred with both automated and manual reprocessing systems.(ABSTRACT TRUNCATED AT 400 WORDS)

To determine trends in a variety of dialysis-associated diseases and practices, the Centers for Disease Control surveyed 1,734 chronic hemodialysis centers in the United States in 1988 in conjunction with the annual facility survey performed by the Health Care Financing Administration. The response rate to a mailed questionnaire was 91%. These 1,586 centers represented 107,804 patients and 28,501 staff members. Over the last 13 years, the incidence of hepatitis B virus (HBV) infection decreased from 3.0 to 0.2% among patients and from 2.6 to 0.1% among staff members. Over the same time, the prevalence of HBsAg-positivity declined from 7.8 to 1.5% among patients and from 0.9 to 0.3% among staff members. Hepatitis B vaccine was given by 90% of the centers. By the end of 1988, 17% of susceptible patients and 53% of susceptible staff members had received all three doses of hepatitis B vaccine. From 1982 to 1988, as a result of receiving vaccine, the prevalence of antibody to HBsAg increased from 12 to 20% among patients and from 18 to 54% among staff. The incidence of non-A, non-B hepatitis in 1988 was reported to be 1.0% among patients and 0.1% among staff members. Fifteen percent of the centers reported pyrogenic reactions in the absence of septicemia among their patients and 45% reported septicemia. The reported incidence of dialysis dementia among hemodialysis patients was 0.2%, with a case fatality rate of 25%. In 1988, 67% of centers reported that they reused disposable dialyzers; these centers treated 72% of the dialysis patient population. Among centers that reused disposable dialyzers, the average number of reuses ranged from 2 to 50 (mean, 11) and the maximum number of times a disposable dialyzer was reused ranged from 3 to 131 (mean, 28).

Reuse of disposable dialyzers was not associated with any increased risk of acquiring HBV infection among either patients or staff. However, pyrogenic reactions occurring in clusters were more frequently reported in centers that reused conventional dialyzer membranes compared with centers that did not. This increased risk was only associated with centers that reused these dialyzers in a manual reprocessing system, a result consistent with those obtained in 1986 and 1987. Eighteen percent of centers reported treating at least some of their patients by high flux dialysis.(ABSTRACT TRUNCATED AT 400 WORDS)

The distribution of immunoglobulins IgG, IgA and IgM in the inner ear tissue from a patient who died of lung bleeding followed after sepsis was studied, and also the normal guinea pig inner ears and the inner ear disorders induced by Kanamycin injection were studied for the distribution of IgG. The temporal bones were fixed in formaldehyde, decalcified in EDTA and embedded in paraffin. The PAP method was used for the demonstration of the immunoglobulins. In both the human inner ear tissue and the normal control inner ear tissue of the guinea pigs deposits of IgG were found in the sensory organs and the endolymphatic sac, however, in the stria vascularis was slight. The severe damaged inner ears induced by Kanamycin the remarkable decreased deposits of IgG were found in the cochlea, but in the endolymphatic sac the remarkable increased deposits of IgG were found. No IgA and IgM were found in the human inner ear tissue.

After ingestion of an unknown amount of formalin with suicidal intent, a 55-year-old female and a 34-year-old male were admitted to the hospital with extensive gastrointestinal corrosive damage, circulatory shock, metabolic acidosis, respiratory insufficiency and impairment of renal function, which rapidly progressed to acute renal failure. Metabolic acidosis was in part due to high plasma levels of formic acid, the main metabolite of formaldehyde, and hyperlactatemia. Both patients underwent hemodialysis and hemofiltration treatment. In the male patient, a gastrectomy had to be performed. The further clinical course in the patients was characterized by sepsis and protracted pulmonary complications. Both patients died after developing adult respiratory distress syndrome and global cardiac insufficiency. In vitro experiments on formaldehyde reactivity to proteins yielded evidence for almost complete but reversible binding to plasma and blood. Formaldehyde probably exerts systemic toxicity in the form of its labile Schiff's base with proteins, but not as free formaldehyde.

Bacteroides fragilis is associated with the formation of intra-abdominal abscesses, whereas other Bacteroides species are rarely involved. Since bacterial clumping may contribute to the survival of bacteria in the face of host defence mechanisms, the hypothesis has been put forward that differences in aggregation between fragilis and non-fragilis strains of Bacteroides may account for their differences in survival in vivo. All seven B. fragilis strains tested formed aggregates within 4 h, but strains not associated with intra-abdominal sepsis--B. vulgatus, B. thetaiotaomicron and B. distasonis--did not form aggregates in vitro. Aggregation occurred at 37 degrees C, but not at 4 degrees C or 20 degrees C. Treatment with pronase partially inhibited aggregation. Periodate treatment killed the cells and caused them to form clumps which were distinguishable from the control aggregates. Heat-killed B. fragilis cells formed similar distinct clumps, but cells killed by glutaraldehyde and formaldehyde did so to a lesser degree. No inhibition was found upon addition of carbohydrates, ethylenediaminetetraacetic acid or after treatment with trypsin. These results demonstrate that aggregate formation occurs with B. fragilis strains alone, and that surface proteins probably mediate this interaction.

During a 3-month period, Pseudomonas cepacia was recovered from the peritoneal fluid of 10 patients having chronic dialysis therapy at a peritoneal dialysis center. Six patients developed clinical evidence of peritonitis; one patient developed septicemia. Epidemiologic studies showed that dialysis on specific peritoneal dialysis machines was associated with an increased risk of infection. Laboratory investigation showed contamination of two machines with P. cepacia. Inadequacies in the cleaning and disinfection practices of the automatic peritoneal dialysis machines were identified. Cross-contamination between machines probably occurred through the peritoneal fluid discharge from infected patients during dialysis. Also, the intermittent 2-hour exposure of the machine to 2% formaldehyde may have been inadequate. P. cepacia has not been isolated from the peritoneal fluid of any peritoneal dialysis patient after machine cleaning and disinfection practices were altered.

Broiler embryos and chicks were exposed to formaldehyde vapors (up to 130 ppm) during the final 3 days of incubation. Bacterial load was significantly lower in a formaldehyde-fumigated hatcher than in an unfumigated hatcher. Hatchability was not affected. To determine if exposure to formaldehyde vapors in the hatcher would affect broilers' ability to tolerate variations in air quality, chicks were placed in either adequately or poorly ventilated confinement facilities for 45 days. Total and respirable dust particles (< or = 5 microns in diameter) increased to a greater extent between 5 and 6 weeks of broiler age in the poorly ventilated facility than in the facility with adequate ventilation. Mortality at 6 weeks of age was significantly higher in broilers exposed to formaldehyde in the hatcher and housed with poor ventilation than in broilers exposed to formaldehyde and raised with adequate ventilation. Six-week body weight, feed conversion, and septicemia/toxemia condemnations were adversely affected by poor ventilation. This study found that the quality of air in the confinement facility had a greater influence on broiler productivity than did exposure to formaldehyde vapors in the hatcher.

Anthrax is caused by Bacillus anthracis, a gram-positive spore-forming bacterium. Septicemia and toxemia rapidly lead to death in infected mammal hosts. Currently used acellular vaccines against anthrax consist of protective antigen (PA), one of the anthrax toxin components. However, in experimental animals such vaccines are less protective than live attenuated strains. Here we demonstrate that the addition of formaldehyde-inactivated spores (FIS) of B. anthracis to PA elicits total protection against challenge with virulent B. anthracis strains in mice and guinea pigs. The toxin-neutralizing activities of sera from mice immunized with PA alone or PA plus FIS were similar, suggesting that the protection conferred by PA plus FIS was not only a consequence of the humoral response to PA. A PA-deficient challenge strain was constructed, and its virulence was due solely to its multiplication. Immunization with FIS alone was sufficient to protect mice partially, and guinea pigs totally, against infection with this strain. This suggests that spore antigens contribute to protection. Guinea pigs and mice had very different susceptibilities to infection with the nontoxigenic strain, highlighting the importance of verifying the pertinence of animal models for evaluating anthrax vaccines.
