Diagnosing the personality organization of drug abusers by rating ego balance

A community-based case-finding sample of 1824 narcotic abusers in Stockholm County was used to standardize a set of rating scales in order to reflect levels of personality organization (PO), in the spirit of Kernberg's theory. PO is assumed to be a function of the ego's capacity to endure inner and outer stress, which manifests itself in the frequency and depth of regressions and the rate of recovery from them. The principles of a method, Rating Ego Balance, for charting the person's characteristic pattern of regression are presented, and its psychometric properties are described on the basis of item response theory. The scales have satisfactory reliabilities and maximal discrimination at subneurotic levels of PO. They show strong construct validity in relation to Kernberg's theory.     

A blinded,controlled evaluation of anxiety and depressive symptoms in patients with fibromyalgia,as measured by standardized psychometric interview scales

The objective of the study was to evaluate the presence of psychopathology in fibromyalgia patients compared with a control group of other rheumatologic patients with pain. Forty-nine fibromyalgia patients and 33 control patients were interviewed blinded, using standardized psychometric scales. Pain was scored on a visual analogue scale. Fibromyalgia patients scored significantly higher than the controls on the Bech-Rafaelsen Melancholia Scale, the Atypical Depression Scale and the Hamilton Anxiety Rating Scale. On the Newcastle Depression Scale there was no difference. In both groups a correlation was found between pain score and psychometric scoring. The fibromyalgia patients scored significantly higher on pain than the controls. After correcting for this difference, the fibromyalgia patients still scored higher on anxiety and depression.     

A new self-rating scale for depression and anxiety states based on the Comprehensive Psychopathological Rating Scale

Self-assessment scales have long been used in psychiatric research even if their validity has often been questioned, one reason being poor the concordance of expert ratings. In clinical practice the use of rating scales is restricted, since they are considered to be time-consuming and perhaps even to disrupt the clinician's rapport with the patient. In the present study, a self-assessment scale, the CPRS Self-rating Scale for Affective Syndromes (CPRS-S-A), was constructed by re-phrasing in a self-rating format 19 items from the original Comprehensive Psychopathological Rating Scale (CPRS) and covering depression, anxiety and obsessional symptoms. In a group of 30 patients with depression syndromes and anxiety syndromes, the CPRS-S-A and the original CPRS were both used on 2 occasions. The patient's Global Assessment of Functioning scores ranged from 30 to 76 (mean 58), which suggests a moderate severity of illness, as does the fact that the majority were outpatients. There was a high degree of concordance between the instruments for most items and for the scores on the subscales for both diagnostic groups (i.e., the Montgomery-Åsberg Depression Rating Scale and the Brief Anxiety Scale, which are both subscales drawn from the CPRS). The time taken to complete the CPRS-S-A varied from 5 to 30 min (mean 19 min for depressive and 16 min for anxiety patients on the first occasion, 13 min for both groups on the second), and the self-rating procedure was readily accepted by both groups of patients. The CPRS-S-A would thus seem to be a promising instrument for quantitative rating of symptoms in ambulatory patients, both in clinical practice and in research.     

Salivary gland 99mTc-scintigraphy: a grading scale and correlation with major salivary gland flow rates

Sequential salivary gland scintigraphy with 99mTc-technetium pertechnetate (Tc-99) is a safe, minimally invasive test for study of major salivary glands. However, its relationship to salivary function has not been investigated in detail. We have investigated the relationship between major salivary gland flow rates and Tc-99 scans and developed a new rating scale using scans of a control group with normal salivary function. Salivary flow rates and Tc-99 scans were obtained from healthy, non-medicated subjects (n = 33) and from xerostomic patients (n = 22). There were significant differences between the groups for salivary flow rates and Tc-99 ratings. Significant correlations were found between salivary flow rates and Tc-99 ratings in the control and xerostomic groups. The Tc-99 rating scale proved reliable in assessing salivary dysfunction, and showed a high inter-examiner correlation. These results demonstrate the usefulness of salivary gland scintigraphy in assessing major salivary gland flow rates and the utility of a new rating scale.     

Separation discrimination with embedded targets

Previous research has shown that separation discrimination thresholds are independent of the internal spatial scale (local spatial frequency) of the targets whose separation is being judged. The experiments reported here tested the generality of this conclusion for separation discrimination of targets that were embedded in an array of identical objects, where crowding could enhance the importance of the scale at which the individual target locations are encoded. No effect of the local spatial scale of the targets was found under these conditions.     

High serum levels of tumour necrosis factor‐α and interleukin‐8 in severe asthma: markers of systemic inflammation?

BACKGROUND: Severe asthma is characterized by elevated levels of pro-inflammatory cytokines and neutrophilic inflammation in the airways. Blood cytokines, markers of 'systemic' inflammation, may be a feature of amplified inflammation in severe asthma. OBJECTIVE: To detect differences in IL-8, TNF-alpha, IL-16 and IL-13 levels in the serum(s) of stable severe and mild-moderate asthmatics related to blood leucocytes proportion, airway calibre and exhaled nitric oxide (NO) levels. METHODS: We assessed cytokine serum levels by ELISA and blood leucocyte counts by an alkaline peroxidase method in 20 healthy controls, 22 mild-moderate [forced expiratory volume in 1 s (FEV1)(%pred): 89+/-3] and 14 severe asthmatics [FEV1(%pred): 49+/-2]. RESULTS: IL-8 and TNF-alpha levels were higher in severe asthmatics than in mild-moderate asthmatics or in controls (P<0.05). No differences in IL-16 and IL-13 levels were detected. Severe asthmatics showed higher circulating neutrophil and eosinophil number than controls (P<0.05). In severe asthmatics, exhaled NO levels were superior than in controls (P<0.05), but inferior than in mild-moderate asthmatics (P<0.05). We found positive correlation between TNF-alpha levels and exhaled NO (r=0.67; P=0.01) or circulating neutrophil counts (r=0.57; P=0.03) in severe asthmatics. CONCLUSION: sTNF-alpha and sIL-8 are markers of 'systemic' inflammation in severe asthmatics, in conjunction with augmented circulating neutrophils, suggesting the involvement of neutrophil-derived cytokine pattern in severe asthma.     

Scales of depression,ill-being and the quality of life—is there any difference? An assay in taxonomy

The application of a model based on the three time dimensions of past, present and future can be used to generate an alternative taxonomy for the classification of depression, ill-being and quality of life. In relation to time, depression can be defined as the passage from a healthy past to a painful present, ill-being as the painful present of the individual and the quality of life (QOL) as the degree to which the subject's present life is commensurate with his aspirations. Such an approach opens up conceptual and methodological areas of research which will allow the construction of a new type of scale. Depression scales should be constructed with two time dimensions: past and present; ill-being scales only refer to the present and QOL scales should have two time dimensions: present and future. It would be possible to combine these three scales into a single scale with three dimensions. Such a scale would enable depression and ill-being to be quantified, accurately diagnosed and monitored. The relative importance of principal symptoms could be assessed, facilitating the choice of therapy and follow-up methods.

Regional Variation and Use of Exception Letters for Cadaveric Liver Allocation in Children with Chronic Liver Disease

The Pediatric End-Stage Liver Disease (PELD) score was designed to reduce subjectivity in liver allocation and to advantage patients with a higher probability of waiting list mortality. The aims of this study were to determine the impact of PELD implementation for children with chronic liver disease and to assess whether PELD met its goal of standardization of liver allocation for children. This study used data reported to the United Network for Organ Sharing (UNOS) registry for children with chronic liver disease receiving primary cadaveric liver transplant between January 2000 and December 2001 (pre-PELD) and March 2002 and July 2003 (PELD). PELD reduced the percentage of children transplanted while in an intensive care unit and as status 1. A calculated PELD score was used for allocation in only 52% of recipients. Thirty percent were status 1 at transplant and PELD scores granted by exception were used for allocation in 18% of patients. There was regional variation in PELD score at allocation and use of exception scores with a significant relationship between PELD score and percentage of exception cases. Regional variation suggests that PELD has not resulted in standardization of listing practices in pediatric liver transplantation.
