An investigation of reliability and validity of the LS/CMI with French offenders.

INTRODUCTION: The Level of Service/Case Management Inventory (LS/CMI) is one of the best-known recidivism risk instruments. In France, this scale is rarely used because no study had yet been carried out to confirm its psychometric properties on samples of French offenders. The aim of this study was to test the psychometric properties of the LS/CMI on samples of violent French prisoners. METHOD: The Level of Service/Case Management Inventory, the BARR-2002R, Historical Clinic Risk-Scale 20 and the Risk for Sexual Violence Protocol were administered to 128 violent offenders. RESULTS-DISCUSSION: The results showed good internal consistency, reliability and convergent validity of the LS/CMI. Assault, robbery and sexual assault were correlated with the LS/CMI. All of these results are discussed and analysed using the international reference literature. CONCLUSION: Confirmation of the psychometric properties of the LS/CMI among French offenders to allow it to be used to assess the risk of recidivism of offenders.

Effectiveness of Selected Air Cleaning Devices During Dental Procedures.

INTRODUCTION: The recent COVID-19 pandemic has underscored the necessity of protecting health care providers (HCPs) against the transmission of infectious agents during dental procedures. To this end, the effectiveness of several air cleaning devices (ACDs) in reducing HCPs exposure to aerosols generated during dental procedures was estimated, separately or in combination with each other. These ACDs were a chairside unit capturing aerosols at the source of generation, and four ambient ACDs: a portable ambient ACD; a negative pressure module; a custom made, fan-operated and wall-mounted air filter (WMAF); and a smaller and passive version of the latter. The last three ACDs were intended for mobile dental clinics (MDCs) only. MATERIALS AND METHODS: This assessment was performed in two different environments: in a dental clinic operatory and in a MDC. Two dental personnel, acting in the roles of dentist and dental assistant, performed on simulated patient aerosol-generating and non-aerosol-generating procedures. For each 5-minute scenario, the cumulative exposure to airborne particulate matter 10 µm in size or smaller (PM10) was determined by calculating the sum of all 1 second readings obtained with personal and ambient air monitors. The effectiveness of the ACDs in capturing PM10 was estimated based on the capability of the ACDs to keep PM10 level at or below the initial background level. RESULTS: In all conditions assessed in the dental clinic operatory, when both the chairside and portable ambient ACDs were functioning, an estimated effectiveness of 100% in capturing PM10 was achieved. In the MDC, in all conditions where the chairside ACD was used without the negative pressure module, an estimated effectiveness of 100% was also achieved. The simultaneous operation of the negative pressure module in the MDC, which led to a room negative pressure of -0.25 inch wc, reduced the chairside ACD's effectiveness in capturing aerosols. Conversely, the use of the WMAF in the MDC in combination with the chairside ACD further reduced exposure to PM10 below the initial background level. Nonetheless, in all conditions assessed in both settings (dental clinic operatory and MDC), larger visible aerosols were produced, often landing on the surrounding environment. A fair portion of these aerosols landed on the inside of the chairside ACD flange. CONCLUSIONS: This assessment suggests that the use of the tested chairside ACD, by capturing aerosols at the source of generation, had the greatest impact on reducing exposure of dental personnel to PM10 produced during dental procedures. This study also indicates that such exposure is further reduced with the addition of an ambient ACD. However, creating a negative pressure room as high as -0.25 inch wc can lead to air turbulence reducing the effectiveness of ACDs in capturing aerosols at the source. Furthermore, the presence of uncaptured droplets and spatter on the surrounding environment supports the need to complement the use of engineering controls with proper administrative controls and personal protective equipment, as recommended by governmental agencies and the scientific community for preventing the transmission of infection in health care settings.

A retrospective cohort study of cancer incidence among patients treated with radiosynoviorthesis.

Radiosynoviorthesis (RS) is an intra-articular injection of a radioactive colloid for the treatment of synovitis administered most often to patients with rheumatoid arthritis or haemophilia. Although highly cost-effective in comparison with surgical or arthroscopic synovectomy, the risk of cancer associated with this treatment is not well known. We evaluated the incidence of cancer in a group of patients treated with RS. A cohort of 2412 adult patients with a variety of underlying conditions (mainly rheumatoid arthritis) and treated with at least one RS between January 1976 and December 2001, was recruited from two centres in Montréal. Cancer incidence and mortality data for cohort members over that time period were obtained from regulatory agencies using linkage. Background rates for all and specific types of cancer were obtained for the provincial (Québec) and national (Canada) population according to age, gender and calendar period categories. Category-specific rates in the cohort were compared with rates in similar categories from the general population generating standardized incidence ratios (SIR). The effects of specific isotope doses and of number of RS treatments were analysed using a Cox-regression model. No increase in the risk of cancer was observed (SIR 0.96; 95% confidence interval 0.82-1.12). There was no dose-response relationship with the amount of radioisotope administered or number of RS treatments. The study provides some indication for the safety of the procedure but homogenous diagnostic groups of younger patients (such as haemophilic patients) receiving RS will need more evaluation.

[Mother-daughter relationship inventory]. / L'inventaire des relations mère-fille.

The present paper centers on the validation of the French-version of the mother-daughter relationship inventory (MDREL), a self-reported questionnaire developed by Inazu and Fox (1980) and translated by Achim. This nine-item self-reported questionnaire assesses young women's perceptions pertaining to the social-emotional support conveyed by their mother, as well as the overall quality of their mother-daughter relationship. The MDREL is the product of factor analyses conducted on 23 statements concerning young women's perception regarding the following dimensions: presence of an open-communication between the mother and the daughter; presence of uncertainties and ambiguities in the description made by the daughter concerning her relationship with her mother; ambivalence expressed by the daughter in regards to mother-daughter rapprochement and intimacy. This instrument is of great interest as it specifically assesses the perceived quality of the mother-daughter relationship during adolescence, a period in which the mother remains an authority-figure and the daughter's sexuality is activated. A total of 126 young women completed the French-version of this self-reported questionnaire. Results indicate good psychometric properties in both validity and reliability. Factor analyses of the French-version of the MDREL yielded two distinct factors, namely an allo-centered and a self-centered assessment. This French-version of the MDREL named l'Inventaire des relations mère-fille (IRMF) can thus be used in studies that focus on mother-daughter relationships. The problematic overtone present in many items suggests that this instrument can be administered to clinical populations.

Synoviorthesis with colloidal 32P chromic phosphate for the treatment of hemophilic arthropathy.

Between 1977 and 1992, we performed ninety-two synoviortheses (destruction of synovial tissue by intra-articular injection of a radioactive agent) on forty-eight patients who had a severe congenital disorder of hemostasis and chronic hemophilic synovitis that was resistant to conventional treatment. Colloidal 32P chromic phosphate was injected intra-articularly: 1.0 millicurie for knees and 0.5 millicurie for other joints. The duration of follow-up ranged from one to fifteen years. The frequency and importance of bleeding decreased in most of the patients. The range of motion of half of the joints remained stable or improved and that of the other half continued to decrease. Radiographic scores worsened progressively despite the decreased frequency of hemarthrosis. In most patients, the extra-articular leakage of the radioactive agent was slight. Chromosome breakages were observed almost exclusively in patients who were seropositive for human immunodeficiency virus and in whom the CD4-lymphocyte count was decreased from normal. The patients' level of satisfaction with the results was high.

Victim-choice polymorphia among serious sex offenders.

The victim-choice polymorphia of 178 sexual aggressors divided into six subtypes, incest offenders, pseudoincest offenders, sexual aggressors of familiar children, sexual aggressors of unfamiliar children, sexual aggressors of familiar women, and sexual aggressors of unfamiliar women, was compared. Results showed that sex offenders remained stable in their choice of victim from one offence to another in terms of victim age, victim gender, and aggressor-victim relationship. Subjects characterised by high levels of polymorphia were pseudoincest offenders and sexual aggressors of familiar women, whereas sexual aggressors of both unfamiliar women and unfamiliar children were characterised by low levels of polymorphia. Recommendations regarding how to further refine sex offender typologies are discussed.

Survival in localized nodal and extranodal non-Hodgkin's lymphomata.

A retrospective analysis of 133 patients with localized nodal and extranodal non-Hodgkin's lymphomata whose staging investigations included marrow aspirate and lymphography shows that more than 60% remain alive and disease-free 4 years after initial therapy. Further relapses may occur in this group, particularly in the nodular lymphomata, but so far the majority of relapses and three quarters of the deaths from disease have occurred within 2 years of diagnosis. Of the entire group of patients, only 15% showed an unequivocally nodular pattern and a further 25% a partially nodular, partially diffuse pattern. Thus, 60% of patients had diffuse lymphoma but differences were observed depending upon the site of presentation. In the nodal Stages I and II cases, whereas only 4 of 55 patients with supradiaphragmatic disease showed a nodular pattern, 12 of 24 infradiaphragmatic presentations had nodular lymphoma. This difference was reflected in a lower relapse rate in the latter group. Mediastinal involvement was uncommon but carried a grave prognosis. As far as it was possible to judge, extension to adjacent nodal areas as a cause of relapse was not a common problem and, as observed previously, relapse was much commoner to a wide variety of extranodal sites than is the case with Hodgkin's disease. In this series marrow involvement was documented in only 7 patients but this surprisingly low frequency might be due in part to infrequent marrow sampling after the initial investigations were completed.

Synoviorthesis with colloidal 32P chromic phosphate for hemophilic arthropathy: clinical follow-up.

Thirty-one synoviortheses were performed in 22 joints of 14 hemophilic patients (aged 12 to 28 years) with chronic synovitis and for whom "conventional treatments" were considered ineffective. Except for patients with inhibitors, conventional treatments included three to six months of adequate prophylactic therapy with the missing coagulation factors, intensive physiotherapy and, when indicated, antiinflammatory agents and orthosis. Colloidal 32P chromic phosphate was injected intraarticularly in doses of 1.0 mCi for knees and of 0.5 mCi for the other joints. Time of follow-up ranged from two to five years. Frequency and importance of bleeding decreased in all patients. Effect on range of motion was best in knees; six of the seven treated improved and one was unchanged. In elbows, flexion-extension was improved in four cases, unchanged in five and decreased in one; pronation-supination was decreased in four cases. Range of motion was not affected in shoulders and ankles except for internal-external rotation which was improved in two of three shoulders treated. The results of 13 synoviortheses in four hemophilic patients with high titer factor VIII inhibitors were comparable to those in hemophiliacs with no inhibitors. However, in three of the four patients synoviorthesis had to be repeated after two to four years for recurrence of synovitis. Extraarticular escape of radioactivity was monitored 62 times for 17 synoviortheses in 12 patients; extraarticular counts never exceeded 4% of the intraarticular counts. Chromosome aberrations were found not to be increased after treatment in the seven patients in whom adequate analysis could be done.
