Exploratory study of the association between insight and Theory of Mind (ToM) in stable schizophrenia patients

Background. Poor insight and impairment in Theory of Mind (ToM) reasoning are common in schizophrenia, predicting poorer clinical and functional outcomes. The present study aimed to explore the relationship between these phenomena.

Methods. 61 individuals with a DSM-IV diagnosis of schizophrenia during a stable phase were included. ToM was assessed using a picture sequencing task developed by Langdon and Coltheart (1999), and insight with the Scale to Assess Unawareness of Mental Disorder (SUMD; Amador et al., 1993). Multivariate linear regression analysis was carried out to estimate the predictive value of insight on ToM, taking into account several possible confounders and interaction variables.

Results. No direct significant associations were found between any of the insight dimensions and ToM using bivariate analysis. However, a significant linear regression model which explained 48% of the variance in ToM was revealed in the multivariate analysis. This included the 5 insight dimensions and 3 interaction variables. Misattribution of symptoms—in aware patients with age at onset >20 years—and unawareness of need for medication—in patients with GAF >60—were significantly predictive of better ToM.

Conclusion. Insight and ToM are two complex and distinct phenomena in schizophrenia. Relationships between them are mediated by psychosocial, clinical, and neurocognitive variables. Intact ToM may be a prerequisite for aware patients to attribute their symptoms to causes other than mental illness, which could in turn be associated with denial of need for medication.     

Supportive and palliative care: experience at the Institut Jules Bordet

The Supportive and Palliative Care Unit of the Institut Jules Bordet officially started its activities in February 1999. Our Unit comprises eight beds (four rooms with one bed each and two rooms with two beds each). We admit advanced cancer patients presenting with severe symptoms whose control is going to require all the expertise of a multidisciplinary team. Whilst these eight beds are identified geographically in the hospital, the team's mobility assures continuity of care for patients who wish to stay in another department. The infrastructure of the Unit and its rooms allow close family members who wish to sleep close to the patients to do so. Otherwise, visits are allowed round the clock, though always with due consideration for patients' comfort. Patients are referred either by a physician working in our Institution (medical oncologist, surgeon, or radiotherapist) or by their family physicians. Less frequently, patients themselves specifically ask to be admitted to our Unit. The activity of the Unit itself during its first year of functioning can be summarized as follows. We admitted 155 advanced cancer patients, for a total number of 210 hospitalizations. Patients were admitted a median of 35 months after their diagnosis and a median of 20 days before death. Stays were generally short (median 11 days). We systematically used quantitative assessment tools (MMSQ, MDAS,EFAT and various VAS) to detect and monitor their symptoms and any complications. The main symptoms on admission were pain, anorexia, asthenia, dyspnea and anxiety/depression. Pain, nausea/vomiting, constipation and cough were controlled in almost all patients, whereas control of asthenia and anorexia was most often insufficient. In 51% of our cases the patients could be discharged home; 40% died in the unit; 4% were transferred to long-term palliative care units and 1% to other units within our Institution (4% were still hospitalized at the time of this analysis).     

Clinical significance of RET/PTC and p53 protein expression in sporadic papillary thyroid carcinoma

AIMS: Rearranged during Transfection (RET)/papillary thyroid carcinoma (PTC) and p53 are two genes involved in the pathogenesis of PTC. It has been suggested that RET/PTC expression is associated with higher rates of local extension and lymph node involvement, whereas p53 mutations are more frequent in poorly differentiated and anaplastic carcinomas. In addition, experimental studies have shown that p53 activity can modify the behaviour of PTC carrying RET/PTC. The aim of this study was to investigate the expression of both RET/PTC and p53 in order to evaluate their usefulness as prognostic factors. METHODS AND RESULTS: Resected specimens of 61 cases of PTC were studied immunohistochemically using a polyclonal antibody to RET and a monoclonal antibody to p53 protein. RET/PTC expression was associated with extrathyroid extension of PTC, at diagnosis (P < 0.05). In contrast, no relationship between p53 immunoreactivity and clinical status was found. In addition, p53 expression was more prevalent among RET/PTC+ patients, and significantly influenced the relationship observed between RET/PTC and extrathyroid extension of the disease. CONCLUSION: Our results suggest that immunohistochemistry for both PTC/RET and p53 could be useful in the clinical evaluation of patients with PTC.     

Endoscopic treatment of persistent alveolar-pleural air leaks with a unidirectional endobronchial valve

The persistent air leaks due to alveolopleural fistula are not an uncommon complication of pneumothorax, particularly secondary ones. Unidirectional flow endobronchial valves designed for lung volume reduction are the latest incorporation to the therapeutic armamentarium. We present the case of a patient with chronic obstructive pulmonary disease (COPD) with persistent pneumothorax in spite of treatment with three pleurodesis which was able to be resolved with the placement of two IBV? valves.     

Birth of a healthy boy after a double factor PGD in a couple carrying a genetic disease and at risk for aneuploidy: case report

Preimplantation genetic diagnosis (PGD) for monogenic diseases is widely applied, allowing the transfer to the uterus of healthy embryos. PGD is also employed for the detection of chromosome abnormalities for couples at high risk of producing aneuploid embryos, such as advanced maternal (>35 years). A significant number of patients requesting PGD for monogenic diseases are also indicated for chromosome testing. We optimized and clinically applied a PGD protocol permitting both cytogenetic and molecular genetic analysis. A couple, carriers of two cystic fibrosis (CF) mutations (c.3849 + 10 KbC > T and c.3408C > A) with a maternal age of 38 years and two previously failed IVF-PGD cycles, was enrolled in the study. After ovarian stimulation, six oocytes were obtained. To detect abnormalities for all 23 chromosomes of the oocyte, the first polar body (1PB) was biopsied from five of the oocytes and analyzed using comparative genomic hybridization (CGH). CGH analysis showed that 1PB 1 and 1PB 4 were aneuploid (22X,-9,-13,+19 and 22X,-6, respectively), while 1PB 2, 1PB 3 and 1PB 6 were euploid. Blastomere biopsy was only applicable on embryos formed from Oocyte 3 and Oocyte 6. After whole-genome amplification with multiple displacement amplification, a multiplex PCR, amplifying informative short tandem repeats (D7S1799; D7S1817) and DNA fragments encompassing the mutation sites, was performed. MiniSequencing was applied to directly detect each mutation. Genetic diagnosis showed that Embryo 6 was affected by CF and Embryo 3 carried only the c.3849 + 10 KbC > T mutation. Embryo 3 was transferred achieving pregnancy and a healthy boy was born. This strategy may lead to increased pregnancy rates by allowing preferential transfer of euploid embryos.     

Further development of a scale of perceived expressed emotion and its evaluation in a sample of patients with eating disorders

High expressed emotion (EE) as measured by the Camberwell Family Interview (CFI) predicts the course of eating disorders (ED). Despite its important contribution to the field, the CFI has two major limitations; it is time-consuming and it does not consider the patient's perspective. Obtaining the patient's view may help shed light on the dyadic nature of caregiver's EE and the patient's illness course. The objectives of our study of 77 patients with ED were to develop further a brief measure to assess the patients' perceptions of their caregivers' EE, the patient version of the Brief Dyadic Scale of Expressed Emotion (BDSEE), and to evaluate its psychometric properties. Three clearly separate factors were identified: perceived criticism, perceived emotional overinvolvement, and perceived warmth. The BDSEE also demonstrated good levels of reliability and construct validity. The BDSEE subscales are significantly related to other measures of the perceived family emotional climate and to the CFI, the gold standard in the field of EE. The clinical implications of the ED patients' perceptions of their caregivers' EE are discussed. Findings support the utility of the expanded BDSEE for both research and clinical practise in assessing the perspective of patients with ED.     

Exophenotypical profile of adolescents with sustained attention deficit: A 10-year follow-up study

We aimed to explore prospectively the relationship between the presence of sustained attention deficit (SAD) in early adolescence and exophenotypical measures of vulnerability to schizophrenia spectrum disorders (personality and psychosocial measures) in early adulthood. Two cohorts of community adolescents were selected in 1993 according to the presence or absence of a CPT-linked SAD. In 2003, both cohorts (Index: n=42, and Control: n=38) were administered the O-LIFE, the SCID-II, the DOI battery and the COPE scale, among other tests. T-tests were used to compare both cohorts. Index subjects showed a higher level of negative schizotypy, avoidant, depressive and narcissistic personality traits, as well as more asocial behavior and poorer use of coping resources than Control subjects did. A SAD in early adolescence may be associated with coping and social deficits, negative schizotypy, and personality traits indicative of emotional disturbance in adulthood. Our results suggest that SAD in early adolescence might be an indicator of psychopathology in adulthood and give support to dimensional models of psychopathology.
