A test of concordance between patient and psychiatrist valuations of multiple treatment goals for schizophrenia

Background While much discussion has been placed on the problem of poor compliance in the treatment of schizophrenia, there has been little discussion on the concordance between patients and psychiatrists, an important contributing factor to patient‐centred care. Objective To estimate the concordance between patients’ and psychiatrists’ (ordinal and cardinal) valuations of multiple goals for schizophrenia treatment and to illustrate the utility of the self‐explicated method in valuing a large number of treatment goals. Design Twenty treatment goals were identified during focus groups and literature review and were presented to patients and psychiatrists during structured interviews. Respondents were asked to rank the multiple treatment goals and rate them on a 5‐point Likert scale. Three scores were calculated based on the ranking (1–20), rating (Likert scale) (1–5) and a self‐explicated method estimated as the product of rating and ranking score (1–100). Concordance was tested using Spearman’s rho for overall ordinal rankings and via anova and F‐test for the cardinal values assigned to a specific treatment goal. Participants A total of 105 outpatients diagnosed with schizophrenia and 160 psychiatrists in Germany. Results Patient and psychiatrist values were concordant when the ordinal properties of their valuations were assessed by rating (ρ = 0.63; P = 0.002), ranking (ρ = 0.51; P = 0.02) and self‐explicated methods (ρ = 0.54; P = 0.01). Significant discordances were found when comparing the cardinal value placed on any given treatment goal using all three approaches, but the self‐explicated method produced a more discerning statistic. Relative to patients, psychiatrists significantly (P < 0.05) overvalued reduced lack of emotion, improved sexual pleasure and improved communication while undervaluing reuptake of activities of daily living, improved satisfaction and recovered capacity for work. Conclusions While there is an overall concordance between patients’ and psychiatrists’ valuation, significantly different valuations on specific goals can be identified. Here, psychiatrists tend to focus on ‘textbook’ outcomes, while patients are more concerned with functioning and living a normal life. This study also demonstrates the importance of comparing the concordance in treatment goals and the importance of preference‐based methods, such as the self‐explicated method, in the study of concordance.     

Changing Concepts of Neuroanatomy Teaching in Medical Education

Background: Anatomy teaching is often described as foundational in the education of physicians, but in recent years there has been increasing pressure on teachers of neuroanatomy to justify its place in the curriculum. Summary: This article examines theoretical assumptions that have traditionally influenced the neuroanatomy curriculum and explains how evolution of thought in the field of medical education has led to a shift in how the pedagogy of neuroanatomy is conceptualized. Conclusions: The widespread adoption of competency-based education, the emphasis on outcome-based objectives, patient- and learner-centered approaches, and a renewed interest in humanistic aspects of medical education have all contributed to a changing educational milieu. These changes have led to a number of curricular innovations. However, questions remain as to what should be taught to medical learners, and how best to teach it.     

Denial in the first days of acute stroke

Denial is a disorder of self-awareness that is frequent after acute stroke, with potential negative influence in the care of patients. The aim of this study was to describe the presence and correlates of denial in acute stroke. We assessed denial in a sample of 180 consecutive acute stroke patients (≤4 days) and in a control group of 50 acute coronary patients using the Denial of Illness Scale (DIS). 41% (74) acute stroke patients (mean DIS score=4.1, SD=2.2, range 0 to 10) and 24% (12) acute coronary patients (mean DIS score=3.2, SD=1.5, range 0 to 10) presented denial (χ²=4.19, p=.04; U=3405.50, p=.01). Denial was more frequent and severe in patients with lower educational level (χ² = 5.04, p=.04; U=2110.50; p=.01), neglect (χ² = 21.38, p=.00; U=1130.50; p=.00), cognitive impairment (χ² = 6.27, p=.02; U=1181.50; p=.01) and after hemispherical lesions (χ² =4.68, p=.05; U=1982.50; p=.04). In logistic regression low educational level, neglect and cognitive impairment were independent factors predicting denial in stroke patients (R²= 21%). Patients with denial can express depressive symptoms. Patients with denial had a worse outcome at discharge (χ² =4.91, p=.04; U=2918.00; p=.03). Denial is a frequent phenomenon after acute stroke. We propose that there is a multifactorial model for the emergence of denial, lower educational as a predisposing condition, and acute stroke due to hemisphere lesion and causing neglect and cognitive impairment as precipitating events. All these factors limit patients’ assessment of their condition and body functions.     

Neuroimaging of emotional brain circuitry in bipolar disorder

Abnormalities in the regulation of emotion and motivational behavior are core features of bipolar disorder (BD) implicating the brain structures that subserve these functions. Converging neuroimaging evidence supports the involvement in BD of a neural system comprised of ventral prefrontal cortex, amygdala, and ventral striatum. Neuroimaging studies demonstrate abnormalities in both the structure and function of these brain regions. Findings in amygdala and ventral striatum in adolescents with BD suggest a neurodevelopmental trajectory for the appearance of regional abnormalities in this neural system. Preliminary studies suggest that mood-stabilizing medications may provide beneficial effects for the structure and functioning of this circuitry. New research directions, including those that integrate genetic studies with neuroimaging research, may provide important insights into the pathophysiologic mechanisms contributing to BD, and point to new strategies for its detection and treatment.     

Neural bases of categorization of simple speech and nonspeech sounds

Categorization is fundamental to our perception and understanding of the environment. However, little is known about the neural bases underlying the categorization of sounds. Using human functional magnetic resonance imaging (fMRI) we compared the brain responses to a category discrimination task with an auditory discrimination task using identical sets of sounds. Our stimuli differed along two dimensions: a speech-nonspeech dimension and a fast-slow temporal dynamics dimension. All stimuli activated regions in the primary and nonprimary auditory cortices in the temporal cortex and in the parietal and frontal cortices for the two tasks. When comparing the activation patterns for the category discrimination task to those for the auditory discrimination task, the results show that a core group of regions beyond the auditory cortices, including inferior and middle frontal gyri, dorsomedial frontal gyrus, and intraparietal sulcus, were preferentially activated for familiar speech categories and for novel nonspeech categories. These regions have been shown to play a role in working memory tasks by a number of studies. Additionally, the categorization of nonspeech sounds activated left middle frontal gyrus and right parietal cortex to a greater extent than did the categorization of speech sounds. Processing the temporal aspects of the stimuli had a greater impact on the left lateralization of the categorization network than did other factors, particularly in the inferior frontal gyrus, suggesting that there is no inherent left hemisphere advantage in the categorical processing of speech stimuli, or for the categorization task itself.     

Treatment and adequacy of treatment of mental disorders among respondents to the Mexico National Comorbidity Survey

OBJECTIVE: This study described the rate and adequacy of mental health service use among participants in the Mexico National Comorbidity Survey and the correlates of any 12-month treatment and of adequate treatment. METHOD: The authors conducted face-to-face household surveys of a probability sample of individuals ages 18 to 65 years in the noninstitutionalized population living in urban areas of Mexico from 2001 to 2002. The use of mental health services and 12-month DSM-IV disorders was assessed with the World Mental Health version of the World Health Organization Composite International Diagnostic Interview. The rates and correlates of any service use and the adequacy of treatment were identified in logistic regression analyses, taking into account the complex sample design and weighting process. RESULTS: The data reported here were based on 2,362 interviews. Fewer than one in five respondents with any psychiatric disorder during the last 12 months used any service during the prior year. The rates of service use by those with mood disorders were somewhat higher. About one in every two respondents who used services received minimally adequate care. CONCLUSIONS: The authors found large unmet needs for mental health services among those with psychiatric disorders. Those with mental illness and those who deliver or seek to improve mental health care in Mexico face enormous challenges.     

Alternative Therapies for the Treatment of Chronic Prostatitis

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a prevalent disease for which there is no standardized therapy. Traditional treatments have included antibiotics, α-blockers, and anti-inflammatories, but those have not proven to be efficacious therapies through many clinical trials. Alternative therapies, such as phytotherapy, acupuncture, and pelvic floor physical therapy, have grown in popularity for the treatment of CP/CPPS. As clinicians continue to explore these alternative therapies, there is an accumulation of strong evidence demonstrating the success of these alternative therapies.     

Cranial epidural empyema with osteomyelitis caused by actinomyces, CT, and MRI appearance

Actinomycosis is an uncommon cause of intracranial infection. Epidural empyema represents about 6% of CNS actinomycotic lesions. A case of an epidural empyema with parietal bone osteomyelitis caused by Actinomyces israelii is presented. Relevant neuroimaging features were bone erosions and a multiloculated collection with annular contrast enhancing on CT. Postoperative MRI revealed extensive involvement of the neighbor dura, falx, and subdural space. MRI was crucial to follow-up the response to antibiotic treatment.
