The Relationship

SummaryChronic Hallucinatory Psychosis (CHP) is typically a French disease entity initially described by G Ballet (1911) and whose diagnostic criteria were established by Pull (1987). This diagnosis is not used in English and German literature. The aim of this study was to investigate the relationship between Pull's criteria for CHP and the criteria for schizophrenia defined by 14 different diagnostic systems and schizoaffective disorders. Seventy-two non-affective psychotic patients (34 men, 38 women), aged 20 to 84, in exacerbated or stabilized phase, were interviewed by the same investigator (SD). The patient distribution between the diagnoses in the different diagnostic systems was carried out using a computerized 208-item checklist. The main results indicated that the definite CHP diagnosis was significantly related to the Catego S + (C = 0.52; P < 0.01), New-Haven, (C = 0.40; P < 0.05) and Schneider (C = 0.54; P < 0.001) systems for schizophrenia and with the depressive-schizoaffective disorder (C =0.39; P < 0.05) in the RDC system. The probable CHP diagnosis was significantly linked with the same systems and with the probable RDC (C = 0.39; P < 0.05) for schizophrenia. These results emphasize that in 13 out of the 14 diagnostic systems, schizophrenic and schizoaffective disorders overlapped with CHP in the French diagnostic system. Among these systems, four schizophrenic diagnoses were significantly linked to CHP. In contrast, the Bleuler system for schizophrenia was not related to CHP at all.

AbstractThe paper presents issues related to the design of an expert diagnostic system of turbine engine functional units. Dedicated diagnostic stations and on-board flight data recorders are the sources of diagnostic signals. The signals were parameterized or identified dynamic models to get a compact representation in the form of a set of parameters. The set of diagnostic parameters was subjected to integer encoding. On this basis, a multi-valued diagnostic model describing the relationship between the set of faults and the set of symptoms (code values of diagnostic parameters) was determined. The proposed approach can be used in the design of expert diagnostic systems for propulsion units of any aircraft.

First Rank Symptoms

Case records of ninety consecutive first lifetime admissions with a hospital diagnosis of schizophrenia were examined for Schneiderian first rank symptoms, the Feighner diagnostic criteria, and the New Haven Schizophrenia Index. Diagnostic exclusion criteria were developed and applied. It is concluded that the hospital diagnosis of schizophrenia is likely to be too broad. Each diagnostic system can increase accuracy of diagnosis, but their exclusion criteria are too vague and the system would be improved by using those given here. Each diagnostic system selects similar groups of patients, and can be applied retrospectively to adequate case records.

SummaryIn the present study, all patients who met the diagnostic criteria for a long-term functional psychosis (LFP) were identified within a defined uptake area in the northern part of the county of Uppsala, Sweden. LFP includes patients 1) with productive psychotic symptomatology, not caused by organic disease, for 1 week or more, at least once during the course of the illness; 2) having been affected by a psychosis for a continuous period of at least 6 months on the same occasion; 3) having shown psychotic features or residual symptoms during the index year; and 4) older than 18 years of age. Primarily, all diagnoses were made according to the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III-R. The prevalence of schizophrenia was 4.2 per 1,000 inhabitants. The prevalence of schizoaffective disorder was 0.7 per 1,000 inhabitants and for delusional disorder, 0.1 per 1,000 inhabitants. When the patients were rediagnosed according to DSM-III, DSM-IV and International Statistical Classification of Disease (ICD)-10, it was found that the prevalence of schizophrenia, schizoaffective disorder and delusional disorder was somewhat lower according to the DSM-III criteria, while the same number of patients fulfilled the criteria according to DSM-IV. If ICD-10 was used, it resulted in a broader concept of schizophrenia and a somewhat more narrow concept of schizoaffective disorder. Thus, the introduction of the new parallel diagnostic systems, ICD-10 and DSM-IV, will result in different, but comparable, prevalence estimates concerning schizophrenia, schizoaffective disorder and delusional disorder.

The Relationship

SynopsisIn an earlier paper (Goldberg et al. 1987) 36 common symptoms of minor psychiatric disorder in general practice were analysed using the technique of latent trait analysis. From this analysis two dimensions of illness emerged, corresponding to anxiety and depression. In the present paper, this symptom-based representation of minor psychiatric illness is used as a framework for comparing four diagnostic systems: General Practitioner (GP) diagnoses, the ID-CATEGO diagnostic system, the DSM-III system and the Bedford College diagnostic system. This analysis clarifies the reasons for disagreement among systems of diagnostic criteria and examines the practical effects of alternative diagnostic algorithms.

The Relationship

A serendipitous cure in a 73-year-old woman of Hunner’s ulcer, urge, nocturia, apical prolapse by a tissue fixation system tensioned minisling (TFS) which reinforced the cardinal, and uterosacral ligaments (USLs) led us to analyse the relationship between Hunner’s ulcer and known pain conditions associated with USL laxity. The original intention was to cure the “posterior fornix syndrome” (PFS), uterine prolapse, and associated pain and bladder symptoms by USL repair. A speculum inserted preoperatively into the posterior fornix alleviated pain and urge symptoms, by mechanically supporting USLs. Hunner’s ulcer, along with pain and other PFS symptoms were cured by USL repair. The concept of USL laxity causing chronic pelvic pain and bladder problems is not new. It was published in the German literature by Heinrich Martius in 1938 and by Petros in the English literature in 1993. These findings raise important questions. As PFS symptoms are identical with those of interstitial cystitis (IC), are PFS and IC similar conditions? If so, then patients with IC who have a positive speculum test are at least theoretically, potentially curable by USL repair. These questions need to be explored.

Abstract Introduction The prevalence of mood disorders such as depression is higher in individuals with obstructive sleep apnea (OSA). Previous studies have found no significant correlation between the apnea-hypopnea index (AHI) and measures of mood and have only included participants who met diagnostic criteria for OSA. The current analysis sought to determine whether mood correlated with AHI in individuals with any AHI values including those that did not meet diagnostic criteria for OSA. Methods 31 volunteers were studied (BMI=29.2±1.0 kg/m2, mean±SE), free from medication and without psychiatric illness or chronic medical conditions with the exception of untreated OSA, uncomplicated hypertension (BP&lt;160/100), or obesity. Following 1-3 weeks of an 8h habitual at home sleep schedule, participants completed the POMS-Brief questionnaire (POMS-B) to assess mood after undergoing overnight polysomnography to determine AHI. Total mood disturbance (TMD) scores were calculated by adding the scores on the POMS-B for each mood state subscale and subtracting the score for vigor-activity. Results The average AHI was 15.3±3.1 (range of 1.1-74.1) events per hour. The average POMS-B TMD score was 21±1.5 (range of 4-46). There was a significant correlation between the POMS-B TMD score and AHI (p=0.037, r2=0.14). This result was also seen in only those individuals with AHI scores &gt;5 (p=0.002, r2=0.4). Conclusion In this sample, individuals with higher AHI values displayed higher TMD scores. These results differ from previous data that showed no significant correlation between AHI and TMD. This is the first analysis to demonstrate a correlation between TMD and AHI while including individuals who didn’t meet diagnostic criteria for OSA. However, the relationship between AHI and TMD was also significant in those with AHI&gt;5. More data on these measures with larger sample sizes and a more equal representation of AHI values should be gathered to provide additional evidence for this relationship.

The Relationship

SynopsisThere has been concern about whether standardized psychiatric interviews make valid diagnoses. Agreements between the Diagnostic Interview Schedule (DIS), as an example of a standardized interview, with independent assessments by a clinician are reasonably high in most studies, but the clinical assessment is itself of uncertain validity. Using predictive ability is an alternative way of judging validity. Data are presented to show that the DIS is almost as good at prediction as a clinician's assessment, but here too there are problems. Because prediction is probabilistic (i.e. the same disorder can have multiple outcomes, and different disorders can share outcomes), it is not possible to say how good prediction has to be to demonstrate perfect validity.Across varied methods of validity assessment, some disorders are regularly found more validly diagnosed than others, suggesting that part of the source of invalidity lies in the diagnostic grammar of the systems whose criteria standardized interviews evaluate. Sources of invalidity inherent in the content and structure of a variety of diagnoses in DSM-III and its heir, DSM-III-R, are reviewed and illustrated, in part with results from the Epidemiological Catchment Area study.The relationship between diagnostic criteria and standardized interviews is symbiotic. While attempts to adhere closely to existing diagnostic criteria contribute to the diagnostic accuracy of standardized interviews, the exercise of translating official diagnostic criteria into standardized questions highlights problems in the system's diagnostic grammar, enabling standardized interviews to contribute to improvements in diagnostic nosology.

SummaryThe concordance and degree of overlap between 13 diagnostic systems for schizophrenia, including the five European systems of Berner, Bleuler, Langfeldt, Pull and Schneider, were evaluated in a cross-sectional study (N = 51) taking the phase of illness (acute or residual) into account. The diagnostic assessments were processed by computer using a 183-item standardised checklist and a data-processing program in GW-Basic language. The inter-rater reliability, as assessed by Kappa coefficient, was good to excellent for each diagnostic system established by this method (K from 0.5 to 1). When comparing the concordance between pairs of 13 diagnostic systems for schizophrenia in acute and residual phase groups, results showed that only two significant relationships were not influenced by the phase of illness (Carpenter x RDC; Catego x Schneider), while 24 were. These included only two relationships in the acute group (Carpenter Catego; Carpenter Schneider) and 22 links between pairs of systems in the residual group. In the acute group, no diagnosis of schizophrenia, including duration criteria such as those of DSM III-R, Feighner, Langfeldt, Pull and RDC, was linked to other systems. In the residual group, the operational systems such as Catego, DSM III-R, Feighner, Newhaven, Pull and RDC had more than five relationships with the other systems whereas the non-operational systems of Bleuler, ICD9, Langfeldt and Schneider had less than four relationships with the others. Except Pull's criteria, the European diagnostic systems, in particular Berner's and Bleuler's, seemed to differ from the others because of the few relationships displayed. The results underline the importance of taking the phase of illness into account when comparing between studies utilizing different diagnostic systems for schizophrenia. They also show the relationships between European and international diagnostic systems, insufficiently established so far.
