RESUMEN
BACKGROUND: The lack of psychometric measures of psychopathology especially in intellectual disabilities (ID) population was addressed by creation of the Psychiatric Assessment Schedule for Adult with Developmental Disability (PAS-ADD-10) in Moss et al. This schedule is a structured interview designed for professionals in psychopathology. The PAS-ADD Checklist was created as a screening tool designed for non-specialists in mental illness, such as families and care staff. The Checklist includes 29 symptoms items graded on a four-point scale. When the score passes the threshold, this indicates the need for further psychiatric assessment. In a study by Moss et al. and a replication by Sturmey et al., the PAS-ADD Checklist was validated and proved reliable as a screening tool for psychiatric disorders in a population of adults with ID. In this study, the French translation of the Checklist is compared with the English version and the psychometric properties are presented for outpatients. METHOD: The French version was created by translation and back translation. Acceptability, internal consistency, inter-rater reliability, factorial analysis and sensitivity/specificity were calculated. RESULTS: Reliability analyses for sub-scales and threshold scales showed good (Cronbach's alpha coefficient greater than 0.7) to acceptable (alpha over 0.6) internal consistency. Cronbach's alpha was over 0.8 when the total scale was considered. Spearman Rank correlations, calculated for 45 pairs of raters on threshold scores, are above 0.66, which is a good sign of accordance between non-specialist raters. Sensitivity and specificity were computed for the number of participants who did and did not cross threshold and for whom a psychiatric disorder was or was not present. The sensitivity was 55% and specificity was 70%. The confirmatory factor analysis with a three-factor solution explained only 46.1%, which suggests a mediocre fit of the data to the model. Even if items have good saturation on each factor, it does not fit with the theoretical model. CONCLUSIONS: The validity of the French version in this sample seems to be acceptable. Specificity was higher than those reported in the English version and sensitivity was lower. The French version was less successful in screening than English version, probably because of the low number of false negatives in this sample, which constitutes recruitment bias in a psychiatric sample. Nevertheless, the French version of the PAS-ADD Checklist is reliable as a general screening tool for psychiatric disorders.

BACKGROUND: Owing to methodological issues, little research has been conducted to examine quality of life (QoL) as a treatment outcome in autism spectrum disorders (ASD) and intellectual disabilities (ID). This study was conducted to combine QoL measures and objective observations of challenging behaviours (CB) in order to evaluate changes over time in adults with ASD and ID who were treated in two different residential programmes; we hypothesised that a decrease in CB would be related to an improved QoL. METHOD: In a longitudinal study (45 months), we followed 31 adults with ASD and ID who had been integrated into two residential programmes [Autism Programme with a Structured Method (PAMS) vs. traditional programme for ID (No-PAMS)] for 2-19 years. QoL [Quality of Life Inventory in a Residential Environment (IQVMR)] and severity of autistic features (Childhood Autism Rating Scales) were evaluated annually. CB, as measured by the Aberrant Behaviour Checklist (ABC), including stereotypic behaviour and inappropriate speech, were repeatedly assessed every 3 months. RESULTS: Observed separately, the groups' results were different. In the PAMS programme, stereotypic behaviour and inappropriate speech (ABC scores) significantly decreased, and the IQVMR total score increased; in contrast, in the comparison group, ABC scores did not change and the IQVMR total score decreased. In all, three mixed-effect ANCOVAs partially confirmed that the PAMS programme had an effect on CB and that QoL improvement did not directly depend on the type of programme but on reducing CB as measured by the ABC. CONCLUSION: The PAMS programme has a positive and indirect influence on QoL by reducing CB.

The purpose of this study was to observe quality of life (QoL) and global evolution of persons with Pervasive Developmental Disorders (PDD) in three different groups. Individualized programs for PDD were compared to traditional programs for intellectual disabilities. Behavioural disorders were repeatedly evaluated using the Aberrant Behaviour Checklist (ABC) and QoL once a year. Little research has investigated this domain due to methodological problems with a non-verbal population. Two preliminary studies of individualized programs showed a significant reduction in behaviour disorders over the course of the study. The recent inclusion of a control group indicates that a traditional program reduces lethargy/social withdrawal (ABC factor 2). A good QoL was measured for the three groups.

BACKGROUND: Tuberculosis (TB) is a persistent public health problem in European cities. France has been unable to report on treatment outcomes until now, and it is not known whether the World Health Organization (WHO) target cure rate of 85% has been met. METHODS: All patients placed under treatment in four hospitals and five out-patient Social Medical Centres in Paris were followed up between 1996 and 2005. Patient monitoring and evaluation were performed using a new software programme, TB-INFO. RESULTS: In a cohort of 1127 patients, 76% had pulmonary TB, of whom 39% were smear-positive, 81% were foreign-born and 9.3% were human immunodeficiency virus positive. At the end of the follow-up, 16% were cured and 54% had completed treatment. Among the 1118 non-multidrug-resistant patients, these percentages were 17% and 46%, respectively, for smear-positive pulmonary patients. Some patients died (1.9%) or failed treatment (0.1%), but many more defaulted (20.5%) as they interrupted treatment (1.5%), were lost to follow-up (19.5%) or were transferred out (7.9%). CONCLUSIONS: This 10-year follow-up of TB patients, managed with TB-INFO software, shows that a patient monitoring system can be implemented in France, providing essential information. Treatment success in this cohort of patients was far below the WHO target.

OBJECTIVE: During the follow-up of a group of patients with active tuberculosis, the predictive potential of several antibody-based assays was evaluated in monitoring treatment efficacy. DESIGN: Eleven patients with bacteriologically documented pulmonary tuberculosis and two patients with tuberculosis pleurisy were studied over a period of 6 months, from the day before treatment to its completion. The kinetics of the humoral response to Mycobacterium tuberculosis was determined by the number of specific circulating antibody secreting cells (ASC) (ELISPOT assay), as well as the titres of specific circulating antibody and specific antibody present in circulating immune complexes (quantitative ELISA). RESULTS: Follow-up ELISPOT assays, performed after initiation of tuberculosis therapy showed a rapid increase of ASC, during the first week, followed by rapid 3-10 fold decline of ASC in 12 of 13 patients tested. This decline occurred more rapidly than the mycobacterial culture conversion. In contrast, follow-up of ELISA assays did not give relevant information in assessing the outcome of treatment. CONCLUSION: In comparison with direct detection of tubercle bacilli in sputum samples, the rapid clearance of specific circulating ASC occurring early on after the onset of therapy could suggest a potential usefulness of ELISPOT in monitoring therapeutic response.

OBJECTIVE: Three types of case management were compared to determine their relative effectiveness in helping people with severe mental illness who were homeless or at risk of homelessness. METHODS: Subjects recruited from a psychiatric emergency room and inpatient units were randomly assigned to one of the three treatment conditions: broker case management, in which the client's needs were assessed, services were purchased from multiple providers, and the client was monitored; assertive community treatment only, in which comprehensive services were provided for an unlimited period; and assertive community treatment augmented by support from community workers, who assisted with activities of daily living and were available for leisure activities. Of 165 subjects recruited, 135 were followed for 18 months. RESULTS: Compared with clients assigned to broker case management, clients assigned to assertive community treatment only and assertive community treatment with community workers had superior outcomes on several variables. They were number of contacts with the assigned treatment program, resource utilization (for example, use of entitlements), severity of thought disorder, activity level, and client satisfaction. Clients in the assertive community treatment only condition achieved more days in stable housing than those in the other two treatment conditions. No significant treatment group effects were found on income, self-esteem, or substance abuse. CONCLUSIONS: Assertive community treatment is superior to broker case management in assisting individuals with serious mental illness who are at risk of homelessness.

Endobronchial tumour obstruction threatens to occur in cases of carcinoma of the bronchus throughout the course of the disease. Such patients can benefit from relief of the bronchial obstruction by several techniques which are currently available. We have treated 149 patients with endobronchial radiotherapy. Seventy three patients were treated with a view to cure, 47 with a palliative dose and 29 received endobronchial radiation in complement with external irradiation. The treatment was carried out in series repeated every 15 days until a maximum of three treatments, consisting of two sessions at 24 hour intervals delivering at each session and irradiating of 7 Gy with a 1 cm catheter. All the clinical signs were relieved and in 79% of patients there was a symptomatic benefit. One hundred and thirty two patients were evaluated by control endoscopy two months after the treatment and 64 had a complete histological remission. The median survival was 14.4 months for patients treated with intent to cure. Obtaining a histological remission was a gauge for prolonged survival (median survival 26.5 months), 11 (7.4%) had massive hemoptysis and 13 (8%) irradiation pneumonitis, all of which occurred some time after the therapeutic procedure. The results confirm the feasibility and the good results of endobronchial irradiation in this field and encourage the idea of controlled multi-centre trials in order to assess a placed of endobronchial radiotherapy in the therapeutic strategy of bronchial cancer.

A 68 year old female presented with an intramedullary metastasis which was found to be caused by an epidermoid bronchial carcinoma. This type of metastasis is a rare complication and a diagnosis is difficult. The authors stress the importance of nuclear magnetic resonance as a non-aggressive diagnostic method which is very sensitive in detecting this type of pathology.

Parasitic and fungal organisms which are likely to cause pulmonary infections in immunosuppressed patients can be detected in broncho-alveolar fluid (BAL fluid). Single and standard methods, such as direct examination of the pellet, eosine-methylene blue fast (RAL 555), cultures in usual mediums of mycology must be systematically applied to this sample and may help detect these organisms without further exploration. If the results are negative, more recent techniques can be used if they present a real asset: an easier reading and mostly an improved sensitivity. Such is the case of immuno-fluorescence assay with monoclonal antibodies for detection of Pneumocystis carinii, and inoculation of MRC5 fibroblast cell line in tissue culture for isolation of Toxoplasma. Fungal pulmonary infections diagnosis has not yet succeeded in benefiting from modern findings: latex tests proposed for the detection of circulating antigens are nor sensitive nor specific, except the "Crypto LA test". Considering the relatively frequent association with other infectious agents, the detection of a parasitic or fungal organism in the BAL fluid should not interrupt investigation of this sample; neither should it lead to hasty conclusions regarding the responsibility of this agent in acute pneumopathy. This role will have to be evaluated according to criteria which are different for each isolated organism.

Pathologic hoof changes in horses and swine can be normalized by administration of biotin. This vitamin has been given orally to women with brittle fingernails or onychoschizia. The aim of the study was to test whether the favorable clinical results could be corroborated by scanning electron microscopy. We investigated the distal ends of the fingernails from 32 persons. They were placed into three groups: group A consisted of 10 control subjects with normal nails, group B comprised eight patients with brittle nails studied before and after biotin treatment, and group C was 14 patients with brittle nails in whom the administration of biotin did not coincide exactly with the initial and terminal clipping of the nails. The thickness of the nails in group B increased significantly by 25%. In group C, the increase was 7%. Splitting of the nails were reduced in groups B and C and the irregular cellular arrangement of the dorsal surface of brittle nails became more regular in all nails of group B and in 8 of 11 nails of group C.

The aim of this study was to test the hypothesis that deficiency of vitamin B6 would produce morphological characteristics of osteochondral lathyrism. To accomplish this goal, morphological characteristics of chick cartilage in which lathyrism was produced by two separate dietary regimens was compared to morphological changes encountered in vitamin B6 deficiency. Vitamin B6 deficiency should reduce activity of lysyloxidase needed for producing intermolecular cross-links. The question to be addressed was: would this latter deficiency impair collagen morphological features and secondarily other structures indirectly by reducing collagen molecular assembly? Failure of cross-linking of collagen in the positive controls was related to a lack of functional aldehyde cross-link intermediates which are blocked by homocysteine and aminoacetonitrile. Day-old-male Lohmann chicks were fed adequate (6 mg/kg) or vitamin B6-deficient diets. Cross-link defects were induced by homocysteine-rich diets (0.6% w/w) or a diet containing aminoacetonitrile (0.1% w/w). Animals were sacrificed at 6 weeks of age and Ossa tarsalia articular cartilage specimens, as well as the proximal end of tarsometatarsus were dissected from the tibial metatarsal joint, a major weight-bearing site. Light microscopic observations revealed reduction of subarticular trabecular bone formation, concurrent with overexpansion of the hypertrophic cell zone. Ultrastructural electron microscopy observation of articular fibro-cartilage indicated significant thickening of collagen fibers in vitamin B6 deficient birds, as well as the positive controls in comparison to that of cage-matched control birds. It was concluded that vitamin B6 deficient cross-linking may be responsible for the observed delay in bone development and aforementioned cartilage histological alterations.

During a ten month period, 117 fibreoptic bronchoscopies and bronchoalveolar lavages (BAL) were performed in human immunodeficiency virus (HIV) infected patients suspected of having opportunistic pulmonary infections. The BAL were classified into 3 groups, according to clinical manifestations related to HIV infection at the time of fibreoptic bronchoscopy: pre-acquired immunodeficiency syndrome (AIDS) (n = 54), AIDS with Kaposi's sarcoma (n = 37), AIDS without Kaposi's sarcoma (n = 26). On chest X-ray, diffuse infiltrates were most common (54%), followed by normal X-rays (24%) and localized infiltrates (18%). Amongst the 117 BAL, 68 (58%) yielded at least one opportunistic agent. In 28 BAL performed for pulmonary signs or unexplained fever with normal chest X-rays, one or several opportunistic agents were isolated in 17 samples of BAL fluid. The most frequently identified opportunistic agents were Pneumocystis carinii (in 38% of BAL) and cytomegalovirus (35%); these were associated in 17% of BAL. There was no statistically significant difference in opportunistic agents among the 3 groups of BAL (pre-AIDS, AIDS with Kaposi's sarcoma, AIDS without Kaposi's sarcoma). In particular, cytomegalovirus was found in BAL with the same frequency in these 3 groups.

The Nifedipine-Total Ischemia Awareness Program was designed to evaluate the prevalence, prognostic implications and effect of therapy on painful and painless myocardial ischemic episodes in a nationwide study of patients with angina pectoris. Three hundred forty-eight patients with at least 2 anginal attacks/week while taking antianginal medications were enrolled at 53 participating centers between September 1, 1986 and March 31, 1988; 312 of the 348 patients formed the study group, while 36 patients formed the control group. At least 1 episode of ST-segment depression during two 48-hour periods of Holter monitoring was present in 136 of the 312 patients in the study group. In these 136 patients, there was a total of 372 episodes of ST-segment depression, of which only 69 (18%) were painful; 85% of the 136 patients had either painless episodes only or both painless and painful episodes. Despite apparently adequate antianginal therapy, 48 patients had greater than or equal to 3 episodes of ST-segment depression/48 hours of ambulatory electrocardiographic monitoring, and 38 patients greater than 60 minutes of ST-segment depression. After nifedipine was administered, there was a 23% reduction in the mean number of episodes of ST-segment depression (2.7 +/- 0.3 to 2.1 +/- 0.2, p less than 0.01). The most pronounced effects were found in the 48 patients with greater than or equal to 3 episodes of ST-segment depression and the 38 patients with greater than or equal to 60 minutes of total ischemic time.(ABSTRACT TRUNCATED AT 250 WORDS)

Two histochemical staining methods, eosine-methylene blue fast (RAL 555) and silver methenamine (modified Grocott's technique), and indirect immunofluorescence assay with an anticyst monoclonal antibody were used to detect Pneumocystis carinii in the broncho-alveolar lavage fluid and induced sputum from 58 HIV+ patients. Immunofluorescence disclosed the largest number of carriers (35 p. cent of examined patients). However, the histochemical staining techniques remain of interest and are the initial method of choice. They are inexpansive and rapid to achieve; less sensitive than immunofluorescence, positive results argue a high enough level of parasitism which leads to clinical manifestations. The increased sensitivity of immunofluorescence has considerably improved the ability to detect Pneumocystis in induced sputum. It allowed us to disclose 18 out 20 carriers (90 p. cent). However when a Pneumocystis is suspected, it is preferable to sample bronchoalveolar lavage fluid. Its examination is quick, easy and quantitative appreciation of results bring important diagnostic arguments. Other parasites, such as toxoplasmas, may also be detected. On the other hand, the examination of expectoration is time consuming and difficult to read and interpret. Therefore, sputum induction for the diagnosis of Pneumocystosis should be reserved to unequiped centers or insufficiently equiped centers (i.e., devoid of intensive care units).

A prospective, randomized study of the potential protective effects of corticosteroids administered as pretreatment against contrast material (CM) reactions is reported. Patients (n = 6,763) from multiple institutions received either a single dose of steroids (32 mg of oral methylprednisolone, approximately 2 hours before CM challenge), a double dose (32 mg approximately 12 hours and 2 hours before CM challenge), or placebo. All contrast injections were with ionic media and were given intravenously. The two-dose (but not the one-dose) corticosteroid regimen provided significant protection. The effect on reaction incidences of a number of historical variables is also tabulated.

The x-ray contrast mediums used over the past three decades have been salts of iodinated acids administered in highly hypertonic concentrations. We conducted a multiinstitutional randomized study of the protective effects of pretreatment with corticosteroids against reactions to intravenous contrast material. We gave 6763 patients two doses of oral corticosteroids (methylprednisolone, 32 mg) approximately 12 hours and 2 hours before challenge with contrast material, one dose of oral prednisolone approximately 2 hours before challenge, or placebo in the same dosages. The two-dose corticosteroid regimen, but not the one-dose regimen, significantly reduced the incidence of reactions of all types (P less than 0.05) except a category of reactions dominated by hives, for which the reduction approached significance (P = 0.055). In recent years, several relatively expensive monomeric nonionic iodinated compounds having approximately half the osmolality of the corresponding ionic compounds and a lower reaction rate have become available. With our two-dose corticosteroid regimen, the incidence of reactions necessitating therapy in patients receiving the ionic medium approximated that reported in an unblinded nonrandomized study of patients receiving a newer intravenous nonionic medium without corticosteroid pretreatment. We conclude that the much less expensive ionic medium, if administered with corticosteroid pretreatment, may serve as a reasonable alternative to intravenous nonionic medium, without loss of safety.
