Local immunotherapy of stomach and intestinal carcinoma by Propionibacterium granulosum.
The effect of cell suspension of Propionibacterium granulosum strain KP-45 injected intratumorally was estimated in patients with advanced malignant neoplastic disease of the upper and lower part of the digestive tract. These patients received no other anticancer treatment, and results of therapy with P. granulosum were compared with a control group of nontreated patients. In the course of immunotherapy, general clinical state, dynamics of tumor growth as judged by endoscopy and morphologic, biochemical and immunologic parameters of the peripheral blood, were evaluated. Treatment with KP-45 preparation usually resulted in partial regression of tumor growth, accompanied by improvement of the clinical state of these patients, as well as reappearance of normal values of blood picture and biochemical parameters. Enhancement of cellular immune response, evaluated by increased number of peripheral blood T lymphocytes and increased skin reactivity to PHA and PPD, was observed. No serious side effects or complications of local immunotherapy were noted. No patients who had immunotherapy suffered from bacterial infection; this was not the case in the control group.

[Prevention of infection with Streptococcus pneumoniae].
Streptococcus pneumoniae is the most common etiologic agent in outpatients pneumonia. Pneumococcal infections are often associated with high mortality risk in immunocompromised patients. An increasing resistance of Streptococcus pneumoniae to antibiotics is observed worldwide. This led to the official recommendation by the STIKO to use the vaccination in special risk groups. The commercially available 23-valent polysaccharide vaccine produces a reliable immune response against pneumococcal infection in children aged over 2 years and adults. The recommendation should be more realized in practice.

Arrest among psychotic inpatients: assessing the relationship to diagnosis, gender, number of admissions, and social class.
The present study of psychotic patients investigates the relationship of specific psychotic diagnoses (i.e., psychoactive-substance-induced psychosis, schizophrenia, bipolar disorder, other DSM-III Axis I psychotic disorders), social class, gender, and number of admissions to the rate of arrest in the community. All admissions with psychotic symptoms to hospitals providing inpatient psychiatric services in the Baltimore area were surveyed during a 6-year period. Study participants were assessed using a modified version of the Diagnostic Interview Schedule. During the course of the interview, patients were asked whether they had ever been arrested as a juvenile or as an adult. After adjusting for age, gender, number of admissions, and social class, we found that patients admitted for psychoactive-substance-induced psychosis were more likely to report having been arrested than patients with other psychotic diagnoses. Patients with schizophrenia were not more likely to have an history of arrest than patients with other psychotic disorders. Number of admissions and social class were independent predictors of history of arrest. The relationship between psychotic diagnosis and history of arrest was modified by gender. Psychotic patients with substance-induced diagnosis who were male were more likely to report a prior arrest in the community than their female counterparts. Our results suggest that type of psychotic diagnosis and social class, in addition to gender and number of admissions, are important predictors of differences in arrest-rate histories among psychotic patients. Gender appears to be an effect modifier of the relationship between psychotic diagnosis and history of arrest.

[Special aspects of implant-associated infection in orthopedic surgery. From the pathophysiology to custom-tailored prevention strategies].
One of the most important risk factors in orthopedic surgery is implant-associated infection. Adhesion and colonization mediated implant infections are extremely resistant to antibiotics and host defences and frequently persist until the biomaterial or foreign body is removed, which is standard therapy. Tissue damage caused by surgery and foreign body implantation increases the susceptibility to infections, activates host defences and stimulates the generation of inflammatory mediators including radicals that are further aggravated by bacterial activity and toxins. Nearly one third of implant-related infections can be prevented by strictly following established infection control guidelines. However, a significant number of implant-associated infections remains. The escape of bacteria from host defence and antibiotic therapy makes the development of infection-resistant materials as anti-microbial drug delivery systems feasible. This concept consists of the sustained delivery of antimicrobial drugs into the local microenvironment of implants avoiding systemic side effects exceeding usual systemic concentrations by magnitudes of order.

Low platelet MAO activity associated with high dysfunctional impulsivity and antisocial behavior: evidence from drunk drivers.
RATIONALE: Low platelet monoamine oxidase (MAO) activity is associated with problem drinking and other deviant behaviors. Since the majority of alcohol abusers are smokers, and tobacco smoke has a direct inhibitory effect on the enzyme, these associations may not be meaningful. OBJECTIVE: The authors compared platelet MAO activity and impulsivity in police-referred subjects caught driving while intoxicated and in control subjects, controlling for smoking. METHODS: Platelet MAO activity was measured radioenzymatically and impulsivity scores obtained from questionnaires. Smoking status was self-reported. RESULTS: Subjects caught driving while intoxicated had significantly higher dysfunctional impulsivity and lower platelet MAO activity than control subjects. This difference in platelet MAO activity between the two groups was significant in non-smokers and ex-smokers. CONCLUSIONS: These findings demonstrate that platelet MAO activity is lower in subjects with socially deviant behavior, and the association of low platelet MAO and problem drinking is not an artifact of smoking.

Adaptive and maladaptive impulsivity, platelet monoamine oxidase (MAO) activity and risk-admitting in different types of risky drivers.
RATIONALE: Platelet monoamine oxidase (MAO) activity reflects serotonergic functioning associated with impulsive behaviour, but the significance of these associations to real-life impulsive behaviour in healthy subjects is not clear. OBJECTIVES: The present study explores impulsivity and platelet MAO activity among people with driving violations. MATERIALS AND METHODS: We compared facets of impulsivity and platelet MAO activity in 1,004 male drivers, out of whom 203 had been caught by the police driving drunk and 292 had been caught exceeding speed limits and committing other non-alcohol-related driving violations. Subjects with speeding and other non-alcohol-related violations were further divided according to their self-reported risk-admitting of exceeding speed limits. RESULTS: While drunk driving was associated only with maladaptive types of impulsivity, exceeding speed limits was associated with functional impulsivity and excitement seeking and, to a lesser degree, with dysfunctional impulsivity. Drunk drivers had lower platelet MAO activity. Risk-admitting high-risk drivers had higher platelet MAO activity, neuroticism-related impulsivity, dysfunctional impulsivity and excitement seeking compared to all other groups and higher functional impulsivity compared to controls. Risk-denying high-risk drivers had only higher functional impulsivity compared to controls. CONCLUSIONS: This study demonstrates different expressions of functional and dysfunctional impulsivity in behaviour. While platelet MAO activity is lower in alcohol-related risky behaviour, non-alcohol-related self-acknowledged risky behaviour is related to higher platelet MAO activity. Thus, deviance towards lower as well as higher end of central serotonergic functioning may lead to impulsive behaviour. While self-reported impulsivity did not correlate with MAO activity, both MAO activity and impulsivity were related to risky behaviour.

Drug utilization review across jurisdictions--a reality or still a distant dream?
OBJECTIVE: There is a perception that many drug usage evaluations do not widely influence prescribing behaviour. The aim of this study was to critically evaluate recent journal articles which fit the Medline definition for Drug Utilization Review (DUR) and which also cover multiple healthcare sites. METHODS: PubMed (National Library of Medicine, NLM) (2003, 2004) was searched using the MeSH topic 'drug utilization'. Retrieved studies were evaluated to ascertain those describing a DUR (measuring drug use against specific criteria). These were subdivided according to whether the DUR was conducted at one site or across many. The multi-centre DURs were critically reviewed, including evaluating whether all phases of a quality cycle were completed and determining aspects of design such as whether the study was prospective or retrospective, any interventions conducted and provision of feedback. RESULTS: A total of 646 unique articles were retrieved. Of these, 495 (77%) did not meet the definition for DUR, while 151 (23%) articles did. Thirty-five (5%) described English language multi-centre DURs; ethics approval was obtained in ten of these and 18 were carried out retrospectively. In all 35 studies some comparator or standard was used, but only eight conducted an intervention and only three provided feedback to the prescribers. CONCLUSION: Most DURs were not conducted across a number of centres. Of the recent published multi-centre DURs most presented only an initial audit and did not complete the quality cycle with feedback, intervention and re-audit. To widely influence prescribing behaviour, the full cycle is required with involvement of as many sites as possible to achieve improvements across many jurisdictions.

Genetic dissection of gene regulation in multiple mouse tissues.
The analysis of the influence of genetic variation on regulation of gene expression at a near-genome-wide level has become the focus of much recent interest. It is widely appreciated that many genes are expressed in a tissue-specific manner and that others are more ubiquitously expressed but relatively little is known about how genetic variation might influence these tissue patterns of gene expression. In this review we discuss what is known about the tissue specificity of the influence of genetic variation and review the challenges that we face in combining hugely parallel, microarray-based gene analysis with equally expensive genetic analysis. We conclude that the available data suggest that genetic variation is essentially tissue specific in its effects upon gene expression and this has important implications for experimental analysis.

G-CSF mobilised granulocyte transfusions in 32 paediatric patients with neutropenic sepsis.
INTRODUCTION: In this retrospective, uncontrolled, observational study, the effect of granulocyte colony-stimulating factor (G-CSF)-stimulated granulocyte transfusions (GTX) in neutropenic paediatric patients with sepsis was evaluated. PATIENTS AND METHODS: Granulocytes were collected from unrelated, ABO group-matched and cytomegalic-antibody compatible donors. For neutrophil mobilization, donors received a single subcutaneous dose of glycosylated G-CSF (Lenograstim, Chugai Pharma, Japan) plus oral dexamethasone (8 mg). In total, 168 (range 1-19 per patient) GTX were transfused in 32 children with a median age of 7.4 (0.25 to 16) years. RESULTS: The underlying diseases comprised predominantly haematooncological malignancies (31 children). In 15 of 32 patients, neutropenia was related to allogeneic stem cell transplantation. All children suffered from sepsis based on international criteria (fever, tachycardia, respiratory rate >2 SD above normal in the context of a suspected or proven infection). In ten children bacteria were isolated, in six children a fungal infection was diagnosed and four sepsis episodes were caused by viral infections. GTX contained a median neutrophil number of 6.3 (range 1.9-13.9)x10(10) per transfusion and obtained a sustained haematological response after GTX. Nineteen out of 32 children survived the neutropenic sepsis, particularly nine out of 11 patients with bacterial sepsis. DISCUSSION: In contrast to the non-survivors, we observed a significant decrease in the C-reactive protein levels shortly after initiation of the GTX treatment in the surviving patients. A clear-cut benefit of GTX for children with neutropenic sepsis cannot be concluded from these data, but in children with (severe) bacterial sepsis refractory to antibiotic treatment, GTX were feasible, safe and could reduce mortality rates in this subgroup of patients.

Investigations on staphylococcal infection of transvenous endocardial pacemaker electrodes.
Infections of pacemaker electrodes and/or aggregate pockets are usually caused by staphylococci, primarily Staphylococcus epidermidis. From in vitro experiments it can be demonstrated that staphylococci are able to adhere to the plastic electrode sheath, to multiply there, and to form microcolonies. Furthermore, the staphylococci produce a slimy amorphous substance with which they are completely covered after a 24-hour incubation. No difference was noticed between the in vitro experiment situation and that occurring in pacemaker infection in humans. This slimy material may be responsible for the maintenance of the infection and the protection of the enclosed bacterial cells against natural host defense mechanisms and antibiotic treatment.

Stimulation of granulopoiesis in pregnant swine and their offspring by Propionibacterium avidum KP-40.
Functional parameters of granulopoiesis were measured in gilts, in pregnant sows and in their offspring. Groups of dams and piglets were injected with a potent immunomodulator--killed lyophilized Propionibacterium avidum KP-40 (PA). Administration of PA (0.1 mg/kg body wt for sows and 0.2 mg/kg body wt for piglets) resulted in significant stimulation of all measured parameters of granulopoiesis as well as in a faster gain of body weight. PA stimulation of sows prior to farrowing had no measurable influence on the development of their offspring.

Psychiatric morbidity in the relatives of patients with DSM-III schizophreniform disorder: comparisons with the relatives of schizophrenic and bipolar disorder patients.
Risks for psychiatric disorders (RDC) among first degree relatives of DSM-III schizophreniform, bipolar, and schizophrenic probands obtained from an epidemiologic sample using family history methods were examined. The relatives of the schizophreniform probands differed from the relatives of the schizophrenic and bipolar probands. The relatives of schizophreniform probands had significantly higher rates of affective illnesses (with the exception of bipolar illness) than the relatives of schizophrenic probands, and they had a significantly higher rate of psychotic affective disorders than the relatives of the bipolar probands.

Schizophrenia: gender and familial risk.
The morbid risks for schizophrenia and any nonaffective psychosis in the first degree relatives of male and female schizophrenic probands were compared utilizing Cox proportional hazards models. The schizophrenic probands (275 male; 106 female) were drawn from a larger sample of hospitalized patients obtained by systematically screening all psychiatric admissions to 15 facilities over a six-year period. Proband diagnoses (DSM-III) were based on a direct assessment of the patient and a review of medical records. The family history method was used to obtain information about the first degree relatives of the probands. Cox proportional hazards models were adjusted for duration of illness of the proband and gender of the relatives. First degree relatives of female probands had significantly higher morbid risks for schizophrenia and nonaffective psychosis than relatives of male probands. The differential risk for schizophrenia in the relatives of male and female probands demonstrated in this study, as well as others, suggests that males and females may be at different risk for subtypes of the disorder.
