Biologic and clinicopathologic factors as indicators of specific relapse types in node-negative breast cancer.

PURPOSE AND METHODS: We evaluated, in 1,800 patients with node-negative tumors treated with locoregional therapy until relapse, the competitive risks for different types of metastasis by cell proliferation (3H-thymidine labeling index [3H-dT LI]), estrogen receptors (ERs), and progesterone receptors (PgRs), and by the integration of biologic and clinicopathologic information. RESULTS: Hormone receptor status and proliferative activity of the primary tumor were not indicative of contralateral failures. Hormone receptors failed to predict the 8-year incidence of locoregional recurrence, but they were significant indicators of distant metastasis and overall survival. The latter finding was confirmed even in multivariate analysis. Conversely, cell proliferation predicted both locoregional and distant metastases and survival, regardless of patient age, tumor size, and ER and PgR status. Recursive partitioning and amalgamation analysis ascribed to cell proliferation an important prognostic role for locoregional recurrence together with patient age and tumor size. CONCLUSION: Biologic markers, in particular cell proliferation, provide information for the different types of relapse and could complement the predictive role of pathologic staging.

A multivariate analysis of blood vessel and lymph vessel invasion as predictors of ovarian and lymph node metastases in patients with cervical carcinoma.

BACKGROUND: To the authors' knowledge there are few available data regarding the influence of lymphovascular space invasion, which has been examined separately as two components (lymphatic vessel invasion [LVI] and blood vessel invasion [BVI]), in the metastasis of cervical carcinoma. METHODS: LVI and BVI, which include capillary vessel invasion, were reviewed retrospectively based on the histopathologic slides of 239 women with cervical carcinoma who were treated with radical hysterectomy. The correlation between lymph node and/or ovarian metastases and LVI, BVI, and other histopathologic factors was investigated by multiple logistic regression analysis. The influence of LVI and BVI on survival was examined by Cox regression analysis. RESULTS: The rate of incidence of LVI was higher than that of BVI in all stages of cervical carcinoma (P < 0.0001 for International Federation of Gynecology and Obstetrics Stage IB and Stage II disease and P < 0.05 for Stage III disease). The incidence rate of BVI increased as LVI became more prominent and there was a significant correlation between the two findings (P < 0.0001). BVI was more frequent in adenocarcinoma/adenosquamous carcinoma than in squamous cell carcinoma (P < 0.05). LVI (P < 0.0001) and parametrial invasion (P < 0.0001) were significantly related to lymph node metastasis on multivariate analysis. Conversely, BVI (P < 0.05) and parametrial invasion (P < 0.0025), as well as adenocarcinoma or adenosquamous carcinoma (P < 0.0005), were significantly related to ovarian metastasis on multivariate analysis. With regard to the prognostic significance of these components, it was found that BVI (hazards ratio [HR] = 2.0), ovarian metastasis (HR = 6.5), and lymph node metastasis (HR = 5.5) were significantly related to a poor prognosis in women with cervical carcinoma. CONCLUSIONS: Ovarian metastasis may occur via hematogenous spread of cervical carcinoma. The results of the current study suggest that BVI, including capillary vessels, that is diagnosed separately from LVI using hematoxylin and eosin stained sections may be an important prognostic factor for patients with cervical carcinoma.

Differential diagnosis between complete and partial mole by TSSC3 antibody completely correlates to DNA diagnosis.

Complete hydatidiform moles (CHMs) are a type of androgenetic fertilization without an ovum. Cases of CHM exhibit a generalized swelling of the villi and are known to be highly associated with persistent disease or carcinoma. In contrast, partial hydatidiform moles (PHMs) also show characteristic hydropic changes among the villi, but the incidence of secondary disease is relatively low. Because PHMs are fertilized by one ovum and two sperm and CHMs are fertilized by one or two sperm alone, we considered whether or not maternally imprinted genes might be useful for achieving a differential diagnosis. The validity of the imprinted genes in CHMs was assessed by implementation of a microarray technique. Among the genes examined, TSSC3, SLC22A1L, KCNQ1, and Decorin were shown to be down-regulated, and TSSC3 was the most markedly suppressed of these genes. In this study, 20 cases of CHM, the diagnosis of which was confirmed by DNA polymorphism, were investigated. In all of these cases, the expression of TSSC3 was completely absent, as determined by Western blot analysis. Conversely, 12 cases of PHM, also diagnosed by DNA polymorphism, were examined here; in all of these 12 cases, TSSC3 was found to be expressed normally. Immunohistochemical (IHC) analysis also produced the same results. The complete silencing of TSSC3 in cases of CHM will provide a novel, convenient strategy for the diagnosis of molar lesions in the placenta.

An analysis of spontaneous conversational speech fluency in children with acquired aphasia.

We report on an instrumental analysis of spontaneous conversational speech (SCS) fluency in acquired childhood aphasia (ACA). Tape-recorded SCS samples of 25 children with ACA (clinical judgment: 12 nonfluent and 13 fluent), and of 12 dysarthric and 12 nonaphasic and nondysarthric right hemisphere injured children were analysed in order to: (1) investigate whether a more refined analysis can objectively contribute to the differentiation of patients who were labelled as fluent or nonfluent on the basis of a clinical judgment: (2) verify whether an instrumental analysis of phonation duration does confirm the subjective estimation of verbal rate (i.e. the number of words produced in a unit of time) in groups of children with acquired neurogenic speech/language disorders frequently met in clinical practice. The results are: (1) phonation rate (i.e. the vocalization percentage) seems to represent an adequate variable to distinguish clinically diagnosed nonfluent aphasic children from speech/language impaired children belonging to other clinical groups of acquired neurogenic speech/language disorders; (2) the verbal rate is highly correlated to the phonation rate in all investigated groups except the dysarthric one. We suggest the instrumental method discussed here might contribute to the differential diagnosis between dysarthric and aphasic disturbances in the acute stage of the disease. Concerning the study of ACA, the main issue of the present investigation is that an objective fluency measurement has succeeded in identifying aphasic children who obviously do not fit in with the standard doctrine on ACA, which claims that ACA is invariably nonfluent irrespective of lesion location.

Risk factors for bleeding after endoscopic retrograde cholangiopancreatography: a systematic review and meta-analysis.

BACKGROUND AND AIMS: ERCP is associated with adverse events, including bleeding, which occurs in up to 1.3% of cases. This meta-analysis aims to identify and quantify risk factors associated with post-ERCP bleeding. METHODS: A comprehensive literature search of electronic databases was conducted from inception to January 10, 2025. Studies were eligible if they used multivariate analysis to identify predictors of post-ERCP bleeding. Risk factors reported in at least 2 studies were pooled using a random-effects model to calculate odds ratios (ORs) with 95% CIs. A further subgroup analysis was performed, including risk factors for postsphincterotomy bleeding and postendoscopic papillectomy bleeding. RESULTS: Twenty-seven studies (4 prospective and 23 retrospective studies) comprising 149,870 patients were included, of whom 1865 experienced post-ERCP bleeding. Twenty potential risk factors were analyzed. The meta-analysis identified several factors significantly associated with increased odds of post-ERCP bleeding in the pooled adjusted analysis, including male gender (OR, 1.24; 95% CI, 1.05-1.46), anticoagulation therapy (OR, 2.75; 95% CI, 1.66-4.56), cirrhosis (OR, 2.54; 95% CI, 1.76-3.65), hemodialysis (OR, 5.82; 95% CI, 3.32-10.18), coagulopathy (OR, 11.01; 95% CI, 2.50-48.40), endoscopic sphincterotomy (EST) (OR, 3.19; 95% CI, 1.69-6.01), precut sphincterotomy (OR, 2.24; 95% CI, 1.52-3.30), and intraoperative bleeding (OR, 2.57; 95% CI, 1.80-3.66). Several factors in the pooled adjusted analysis were not found to be significantly associated with higher odds of post-ERCP bleeding, including high body mass index (BMI), nonsteroidal anti-inflammatory drug (NSAID) use, antiplatelet therapy, thrombocytopenia, common bile duct stones, cholangitis, endoscopic papillary balloon dilatation, and covered self-expandable metal stent insertion. CONCLUSIONS: This meta-analysis identified that the anticoagulation therapy, cirrhosis, hemodialysis, coagulation disorder, EST, precut sphincterotomy, and male gender are associated with increased odds of post-ERCP bleeding in the pooled adjusted analysis. Conversely, age, high BMI, cholangitis, choledocholithiasis, pancreatic duct stones, needle-knife sphincterotomy, NSAID use, and antiplatelet therapy were not significantly associated with higher odds of post-ERCP bleeding in the pooled adjusted analysis. Incorporating our results into a prediction model may assist in identifying patients at increased risk, optimizing informed consent, and guiding prevention and management strategies for post-ERCP bleeding.

A 10-Mb paracentric inversion of chromosome arm 2p inactivates MSH2 and is responsible for hereditary nonpolyposis colorectal cancer in a North-American kindred.

Genomic deletions of the MSH2 gene are a frequent cause of hereditary nonpolyposis colorectal cancer (HNPCC), a common hereditary predisposition to the development of tumors in several organs including the gastrointestinal and urinary tracts and endometrium. The mutation spectrum at the MSH2 gene is extremely heterogeneous because it includes nonsense and missense point mutations, small insertions and deletions leading to frameshifts, and larger genomic deletions, the latter representing approximately 25% of the total mutation burden. Here, we report the identification and molecular characterization of the first paracentric inversion of the MSH2 locus known to cause HNPCC. Southern blot analysis and inverse PCR showed that the centromeric and telomeric breakpoints of the paracentric inversion map within intron 7 and to a contig 10 Mb 3' of MSH2, respectively. Pathogenicity of the paracentric inversion was demonstrated by conversion analysis. The patient's lymphocytes were employed to generate somatic cell hybrids to analyze the expression of the inverted MSH2 allele in an Msh2-deficient rodent cellular background. The inversion was shown to abolish MSH2 expression by both northern and western analysis. This study confirms that Southern blot analysis still represents a useful and informative tool to screen for and identify complex genomic rearrangements in HNPCC. Moreover, monoallelic expression analysis represents an attractive approach to demonstrate pathogenicity of unusual mutations in autosomal dominant hereditary conditions.

Factors predicting progression of IgA nephropathies.

The difficulties in defining the natural history of primary IgA nephropathy (IgAN) depend upon the pre-selection of patients for renal biopsy, a true individual variability - ranging from asymptomatic to rapidly progressive forms - as well as the use of different classifications of the renal lesions and statistical analyses sometimes carrying incorrect modalities. Long-term natural history studies have demonstrated that the rate of progression has an extremely wide range, from 5 to 25% after 10 years and 25-50% at 20 years, and complete remission is reported as well in 5 to 30% of cases. A geographic variability has been confirmed in a tri-continental study, explainable only partly by the earlier referral. Among the factors predicting progression, the more frequent in cohorts showing worse actuarial survival at 10 years are those associated with the advanced phases of renal damage, as increased creatinine level, arterial hypertension and nephrotic range proteinuria. A multivariate statistical approach showed the relevance of proteinuria during follow-up (percent duration of massive proteinuria or proteinuria at 1 year) more than proteinuria at the onset. Mean blood pressure value (MAP) and proteinuria during follow-up were independent predictors of end-stage CKD. Note the predictive value of severe microscopic hematuria in several studies. As far as histological features are concerned, strong independent predictors of progression at Cox multivariate analysis are the severity of glomerular sclerosis and interstitial fibrosis. The presence of crescents was a risk factor in almost all studies at univariate analysis, but did not maintain a significant predictor value at multivariate analysis. Conversely the association between crescents and tuft adhesions, possibly resulting from previous segmental necrosis, was found to be a significant risk factor. The extent of mesangial proliferation and parietal expansion of deposits was not significantly associated to unfavourable prognosis at multivariate analysis. The analysis of risk factors for progression of IgAN related to Henoch-Schoenlein purpura (HSP) failed to demonstrate any prognostic value for the presence and severity of extra-renal signs of vasculitis or presence of triggering factors. At multivariate Cox analysis, age and mean proteinuria during follow-up were powerful independent prognostic predictors. Proteinuria at baseline was not significantly related to renal progression, nor were hypertension or impaired renal function at onset. It is of interest that data at onset and at renal biopsy (renal function impairment, hypertension, nephrotic-range proteinuira) were not significantly related with renal detrimental progression. Neither had prognostic value the finding of crescents involving up to 75% of glomeruli.

Do people with schizophrenia display theory of mind deficits in clinical interactions?

BACKGROUND: Having a 'theory of mind' (ToM) means that one appreciates one's own and others' mental states, and that this appreciation guides interactions with others. It has been proposed that ToM is impaired in schizophrenia and experimental studies show that patients with schizophrenia have problems with ToM, particularly during acute episodes. The model predicts that communicative problems will result from ToM deficits. METHOD: We analysed 35 encounters (> 80 h of recordings) between mental health professionals and people with chronic schizophrenia (out-patient consultations and cognitive behaviour therapy sessions) using conversation analysis in order to identify how the participants used or failed to use ToM relevant skills in social interaction. RESULTS: Schizophrenics with ongoing positive and negative symptoms appropriately reported first and second order mental states of others and designed their contributions to conversations on the basis of what they thought their communicative partners knew and intended. Patients recognized that others do not share their delusions and attempted to reconcile others' beliefs with their own but problems arose when they try to warrant their delusional claims. They did not make the justification for their claim understandable for their interlocutor. Nevertheless, they did not fail to recognize that the justification for their claim is unconvincing. However, the ensuing disagreement did not lead them to modify their beliefs. CONCLUSIONS: Individuals with schizophrenia demonstrated intact ToM skills in conversational interactions. Psychotic beliefs persisted despite the realization they are not shared but not because patients cannot reflect on them and compare them with what others believe.

A socially organized basis for displays of cognition: procedural orientation to evidential turns in psychic-sitter interaction.

Discursive psychology has been concerned with investigating how aspects of mind--cognitions, personality, identity, memory, attitudes, attributions, etc.--are warrantably invoked and indexed in the particulars of language use in a variety of discursive contexts. By drawing upon the method and findings of conversation analysis (CA), researchers have been able to show how displays of mind may be achieved with respect to the speakers' production of discursive activities, such as warranting versions of events. One of the key features of CA is the identification of sequences of conversational actions and their oriented-to-properties. This study argues that a focus on sequential activity can be harnessed to discursive psychological investigations to reveal how the relevance of displays of mind is embedded in the structure of verbal activities. To illustrate this methodological recommendation, the study describes a recurrent interactional episode in consultations between psychics and their clients, or sitters, in which participants realize collaboratively the demonstration of (albeit parapsychological) cognition.

The expression of aversion to medicines in general practice consultations.

Although the relevance of patients' views about medicines for their medicine taking behaviour is now well established, little is known about the ways in which these views are discussed in primary care consultations. In particular, many studies have demonstrated patients' aversion to medicines. This paper examines the form that aversion talk takes in the consultation and how doctors respond to patients' expression of aversion to medicines. It is based on a dataset of 35 case studies of general practice consultations in England. In interviews with researchers, aversion to medicines was expressed in 34 of the 35 cases. In consultations with doctors, aversion was expressed in 10 cases. The interactional dimension of aversion talk in consultations was analysed using Conversation Analysis, and two general patterns were identified. Aversion could be used as an interactional resource, or it could be a topic in its own right. If used as an interactional resource, no real discussion of patients' views of medicines took place. When aversion was a conversational topic in its own right, two situations were observed. Firstly, the doctor elicited patients' views directly. Secondly, patients initiated aversive talk using a range of indirect strategies to do so. Even when patients managed to express their aversion to medicines, doctors did not engage them in any real discussion of their views. A scheme of interpretation is suggested to explain these findings. In this scheme patients perceive medicines to be an extension of the doctor and to be beneficial. In this view it is right for doctors to prescribe medicines and for patients to take medicines. The results of this paper suggest that using aversion as an interactional resource might be the only safe way for patients to express their aversion without seeming to breach the social contract.

Molecular basis of the altered antigenic expression of RhD in weak D(Du) and RhC/e in RN phenotypes.

The RH blood group locus is composed of two sequence-related genes, RHD and RHCE, encoding the D, Cc, and Ee antigens in common Rh-positive phenotypes. In this report, we have analyzed the molecular basis of Rh antigens expression in weak D (Du) and RN donors, in whom there is a severe reduction of the D and C/e antigens, respectively. Genomic and transcript analysis of three unrelated low-grade weak D (Du) variants indicated that the very low expression of the D antigen is not the result of rearrangement or mutation in the coding sequence of the RHO gone. Accordingly, weak D (Du) erythrocytes should carry a normal RhD polypeptide, which is in agreement with the observation that these variants never produce anti-D antibodies. Comparative polymerase chain reaction analysis showed a lower steady-state level of RhD transcripts in weak D (Du) reticulocytes, as compared with normal RhD-positive controls, thus providing direct evidence that the difference between the D antigen of D-positive and weak D (Du) red blood cells is quantitative only. Conversely, analysis of the molecular genetic basis of the RN phenotype Indicated that the severely decreased expression of the RhC and Rhe antigens in three variants is associated with a qualitative alteration identified as a segmental DNA exchange between the RHCE and RHD genes. These genomic rearrangements, which resulted in hybrid RhCe-D-Ce proteins expressing the low frequency Rh32 but not the high incidence Rh46 antigens, involved either axon 4 alone or both exons 3 and 4. These findings show that an identical phenotypical alteration of Rh antigens (reduced expression) may result either from a quantitative or a qualitative alteration of the RH genes expression.

Object transfer, intersubjectivity and third position repair: early developmental observations of one child.

Interaction sequences are explored which are initiated by either child requests or adult offers of objects. The focus is on those sequences in which the child does not want an object that is passed to her, and on how the child manages such an interactional contingency. Throughout the age range in question, 1;0 to 1;8, the child uses re-requests where this contingency occurs in request sequences. The analysis traces the development of these re-requests and compares them with other forms of re-request. In addition, differences are uncovered as between request and offer sequences concerning the child's ways of dealing with an unwanted object that is passed to her. Linkages are made between these themes and work on third position repair within conversation analysis. Home based video-recordings of one child between the ages of 1;0 and 1;8 constitute the data base for the study.

Metabolism of delta-Aminolevulinic Acid in Red and Blue-Green Algae.

delta-Aminolevulinic acid was incorporated in vivo into C-phycocyanin and B-phycoerythrin in two species of the Rhodophyta (Cyanidium caldarium, Porphyridium cruentum) and three species of the Cyanophyta (Anacystis nidulans, Plectonema boryanum, Phormidium luridum). Amino acid analysis of phycocyanin-(14)C from C. caldarium cells which had been incubated with delta-aminolevulinate-4-(14)C showed that 84% of the radioactivity incorporated was present in the phycocyanobilin chromophore and less than 16% of the radioactivity cochromatographed with amino acids. These results indicate that delta-aminolevulinate is utilized predominantly via the porphyrin pathway in C. caldarium. Conversely, analysis of phycocyanin-(14)C prepared from cells of A. nidulans, P. boryanum, and P. luridum which had been incubated with radiolabeled delta-aminolevulinate demonstrated that 85%, 81%, and 93%, respectively, of the radioactivity incorporated cochromatographed with amino acids. The ratio of incorporated radioactivity in amino acids and phycoerythrobilin was 40:60 in P. cruentum phycoerythrin obtained from cells which had been incubated with delta-aminolevulinate-4-(14)C. Succinate-2-3-(14)C appeared to be as good a carbon source of amino acids as did C(4) and C(5) of delta-aminolevulinate. These data demonstrate a major alternate route (other than the porphyrin pathway) of delta-aminolevulinate metabolism in red and blue-green algae. The factors responsible for the extent to which delta-aminolevulinate is utilized for synthesis of porphyrins and their derivatives and routes of delta-aminolevulinate catabolism in the organisms employed are discussed.

Physiologic versus neoplastic C-cell hyperplasia of the thyroid: separation of distinct histologic and biologic entities.

BACKGROUND: Although hyperplasia of C-cells has been described in association with various pathologic and physiologic conditions, criteria for its diagnosis are poorly defined. Both neoplastic and physiologic C-cell proliferations have been lumped together under the umbrella designation of C-cell hyperplasia (CCH), creating considerable confusion among clinicians and pathologists. METHODS: in order to compare the morphologic and immunohistochemical characteristics of the two major types of CCH, we examined thyroid sections of 17 patients with familial forms of C-cell hyperplasia and/or neoplasia and tissue sections of 19 thyroid glands known to have reactive or physiologic CCH (at least 50 C-cells per one low power field, 100X). Hematoxylin and eosin (H & E) stained sections and immunohistochemical stains for calcitonin were assessed in each case. RESULTS: Physiologic or reactive CCH was not recognized with certainty on H & E stains in any of the cases due to morphologic similarities between C-cells and adjacent follicular cells. Detection of this form of hyperplasia, which was predominantly diffuse, required calcitonin immunostains and quantitative analysis. Conversely, nodular and diffuse neoplastic CCH was easily identified with conventional H & E stains at the periphery of 11/12 (92%) familial medullary thyroid carcinomas (MTC). In the other five cases, neoplastic C-cell hyperplasia was the only pathologic finding on thyroidectomy performed for elevated serum calcitonin levels detected via provocative biochemical screening or identification of the mutated RET proto-oncogene by genetic analysis. The C-cells in this neoplastic form of CCH were large, mildly to moderately atypical, and confined within the basement membrane of thyroid follicles. Moreover, these cells were cytologically indistinguishable from those of invasive MTC cells. CONCLUSIONS: Physiologic and neoplastic CCH are biologically and morphologically distinct entities. The former cannot be recognized with certainty with conventional stains and requires immunohistochemistry and quantitative analysis for diagnosis. The latter consists of mildly to moderately atypical C-cells that can be identified with H & E stained sections. Consequently, the number of C-cells is of no importance for the diagnosis of neoplastic CCH which is considered to be the precursor (medullary carcinoma in situ) of invasive medullary carcinoma.

Environment-specific amino acid substitution tables: tertiary templates and prediction of protein folds.

The local environment of an amino acid in a folded protein determines the acceptability of mutations at that position. In order to characterize and quantify these structural constraints, we have made a comparative analysis of families of homologous proteins. Residues in each structure are classified according to amino acid type, secondary structure, accessibility of the side chain, and existence of hydrogen bonds from the side chains. Analysis of the pattern of observed substitutions as a function of local environment shows that there are distinct patterns, especially for buried polar residues. The substitution data tables are available on diskette with Protein Science. Given the fold of a protein, one is able to predict sequences compatible with the fold (profiles or templates) and potentially to discriminate between a correctly folded and misfolded protein. Conversely, analysis of residue variation across a family of aligned sequences in terms of substitution profiles can allow prediction of secondary structure or tertiary environment.

How primary care providers talk to patients about alcohol: a qualitative study.

BACKGROUND: Alcohol misuse is a common and well-documented source of morbidity and mortality. Brief primary care alcohol counseling has been shown to benefit patients with alcohol misuse. OBJECTIVE: To describe alcohol-related discussions between primary care providers and patients who screened positive for alcohol misuse. DESIGN: An exploratory, qualitative analysis of audiotaped primary care visits containing discussions of alcohol use. PARTICIPANTS: Participants were 29 male outpatients at a Veterans Affairs (VA) General Internal Medicine Clinic who screened positive for alcohol misuse and their 14 primary care providers, all of whom were participating in a larger quality improvement trial. MEASUREMENTS: Audiotaped visits with any alcohol-related discussion were transcribed and coded using grounded theory and conversation analysis, both qualitative research techniques. RESULTS: Three themes were identified: (1) patients disclosed information regarding their alcohol use, but providers often did not explore these disclosures; (2) advice about alcohol use was typically vague and/or tentative in contrast to smoking-related advice, which was more common and usually more clear and firm; and (3) discomfort on the part of the provider was evident during alcohol-related discussions. LIMITATIONS: Generalizability of findings from this single-site VA study is unknown. CONCLUSION: Findings from this single site study suggest that provider discomfort and avoidance are important barriers to evidence-based brief alcohol counseling. Further investigation into current alcohol counseling practices is needed to determine whether these patterns extend to other primary care settings, and to inform future educational efforts.

Reflective questions in health counseling.

This study explores questions that nurses ask patients in order to awaken reflection on their health behavior in health counseling. Thirty-eight counseling situations were videotaped in a hospital. The data were analyzed using conversation analysis which was adapted for the purpose of this study. Nonverbal communication supported speech and was interpreted alongside it. This study found that nurses used only a few reflective questions, most of which were future-oriented or introduced hypotheses. In a nonreflective discussion, nurses used only check-up and alternative questions to get information about patients' illnesses and health care measures. Findings indicated that reflective conversation began with check-up questions about patients' immediate situation, followed by questions about patients' feelings in the past, present, or future. On the third level of questioning, the structure might vary between embedded questions, check-up, alternative, or feeling questions. Nonverbal communication supported the discussion. Reflective questions tended to ensure patient-centered conversation and might improve the effectiveness of health counselling.

Getting and giving information: analysis of a family-interview strategy.

This paper reports on a videotape study of particular aspects of the two-part interview developed by Selvini-Palazzoli et al. (8, 9). The first segment is a "search for information," the second part the application of an intervention based on the information gathered in the first part. The study focused on the strategies of information retrieval on the premise that they are significant for the quality of information gathered and for the criteria implicitly conveyed by the therapist that in turn have their own substantial impact on the system. We have employed theories of communication, particularly conversational analysis, that are a departure from the epistemological premises of systems theory and communication pragmatics proposed by Selvini-Palazzoli et al. as the theoretical underpinning of their interview technique.
