Borderline patients have difficulties describing feelings; bipolar II patients describe difficult feelings. An alexithymia study.

OBJECTIVE: Apparent similarities between borderline personality disorder (BPD) and bipolar II disorder (BIP-II) contribute to clinical difficulties in distinguishing between the disorders. Here, we aimed to explore how subjective Difficulties with the Identification and Description of Feelings (DIDF), a major constituent of the alexithymia construct and assessed as a part of the Toronto Alexithymia Scale (TAS), are related to relationship problems and health complaints in these groups. METHODS: Twenty-two patients with BPD; 22 patients with BIP-II; and 23 healthy controls (HC) completed TAS. Health complaints, including symptoms associated with mood swings, were assessed with the Giessener Subjective Complaints List (Giessener Beschwerdebogen-GBB), and relationship problems with the Health of the Nation Outcome scale, Relationship item (HoNOSR). Bivariate correlations were run. RESULTS: Both patient groups had high DIDF and GBB scores. In BPD only, there was a significant positive correlation between DIDF and HoNOSR. In BIP-II only, there was a significant positive correlation between DIDF and GBB total score. In BIP-II, DIDF correlated highly with those GBB subscales assessing symptoms typically occurring during bipolar mood swings (cardiovascular and gastrointestinal symptoms, exhaustion). CONCLUSION: Our results suggest that in BPD, high DIDF scores represent genuine problems with identifying and describing emotions which are expected to correlate with relationship problems. In BIP-II, high DIDF scores could potentially represent difficulties with understanding the unpredictable symptoms of bipolar mood swings. The findings suggest that difficulties with identifying and describing feelings in patients should be carefully explored to increase the validity of the diagnostic evaluation.

Regional cortical thinning may be a biological marker for borderline personality disorder.

OBJECTIVE: We investigated cerebral cortical thickness and its relation to measurements of difficulties with identifying and describing emotions in patients with borderline personality disorder (BPD). METHOD: Eighteen SCID-II-diagnosed female patients with BPD and 21 healthy female controls underwent magnetic resonance imaging and completed the Toronto Alexithymia Scale (TAS). First, regional cortical thickness across the cerebral surface was compared between patients and healthy controls. Then, analyses of the association between cortical thickness and TAS subscales were performed in patients. RESULTS: Compared with controls, patients exhibited clusters of significantly reduced cortical thickness in the left medial and lateral prefrontal cortex, left temporoparietal junction, bilateral temporal poles, and bilateral paracentral lobules. Significant negative associations were observed between cortical thickness and the 'Difficulties Describing Feelings' TAS subscale (DDF) scores in patients. The anatomical distribution of these associations was highly overlapping with the group differences in cortical thickness. CONCLUSION: The pattern of regions exhibiting cortical thinning in patients resembles a network of cortical structures repeatedly shown to be involved in social cognition. The results of the DDF analyses suggest that the thinning may partly be related to interpersonal dysfunction in patients with BPD. The pattern of thinning may represent a potential biological marker for BPD.

Traumatic stress, mental health, and quality of life in adolescents with esophageal atresia.

INTRODUCTION: We aimed to investigate QoL in EA patients in relation to comparison groups and to clinical factors including experienced traumatic stress. MATERIAL AND METHODS: Adolescents with EA in Norway born between 1996 and 2002 were included. Clinical assessment and patient's characteristics were collected. Quality of life (PedsQL), traumatic stress (IES-13) and mental health (SDQ-20) were compared to groups of healthy controls, children with acute lymphoblastic leukemia (ALL) and kidney transplanted children (TX). RESULTS: 68 EA adolescents participated. Total scores for PedsQL were not different from the healthy group and ALL patients, but significantly better than the TX patients. The subscale for physical performance was significantly lower than in healthy adolescents, and nine (17%) patients had scores ≤70 indicating reduced health status. Five EA adolescents (12%) had mental health scores suggesting a psychiatric disorder, and six (9%) reported high traumatic stress scores with a significant correlation to days on ventilator in the neonatal period. The strongest predictors for quality of life among EA adolescents were self-reported mental health, posttraumatic stress and GERD symptoms. CONCLUSION: Scores for Quality of life in the EA group are good except for subscale for physical performance. Symptoms of posttraumatic stress, mental strain and gastroesophageal reflux are predictors of reduced QoL.

The Intrinsic Enzyme Activities of the Classic Polyoxometalates.

The mimicking enzyme activities of eighteen classic POMs with different structures, Keggin (H3PW12O40, H4SiW12O40, H4GeW12O40, K4GeW12O40, H3PMo12O40, H4SiMo12O40 and Eu3PMo12O40), Wells-Dawson (H6P2Mo18O62, α-(NH4)6P2W18O62 and α-K6P2W18O62·14H2O), lacunary-Keggin (Na8H[α-PW9O34], Na10[α-SiW9O34], Na10[α-GeW9O34] and K8[γ-SiW10O36]), the transition-metal substituted-type (α-1,2,3-K6H[SiW9V3O34] and H5PMo10V2O40), sandwich-type (K10P2W18Fe4(H2O)2O68) and an isopolyoxotungstate (Na10H2W12O42) were screened and compared. The mechanisms and reaction conditions of POMs with mimicking enzyme-like activities were also analyzed. The results shown that the structures, the hybrid atoms, the coordination atoms, the substituted metal atoms, pH and substrate are the effect factors for the enzyme mimic activities of POM. Among the eighteen POMs, H3PW12O40, H4SiW12O40, H4GeW12O40, α-(NH4)6P2W18O62, α-K6P2W18O62·14H2O, Na8H[α-PW9O34], Na10[α-SiW9O34], Na10[α-GeW9O34], K8[γ-SiW10O36], K10P2W18Fe4(H2O)2O68 and Na10H2W12O42 had the peroxidase activities. Eu3PMo12O40, H3PMo12O40, H4SiMo12O40, α-1,2,3-K6H [SiW9V3O34], H6P2Mo18O62 and H5PMo10V2O40 showed the oxidase-like activities. K4GeW12O40 did not show the peroxidase and oxidase activities. The Na8H[α-PW9O34], Na10[α-SiW9O34] and Na10[α-GeW9O34] showed intrinsic enzyme activities at alkaline conditions, which were different from other type of POMs. The sandwich-type K10P2W18Fe4(H2O)2O68 displayed the strongest peroxidase activity, which is similar to natural horseradish peroxidase.

Viral antibodies in infectious mononucleosis.

Patients with Epstein-Barr virus (EBV) infectious mononucleosis (IM) usually develop heterophilic antibodies and some autoantibodies. Antibodies to rubella, measles, adeno-, entero-, herpes simplex, cytomegalo- and varicella-zoster viruses were titrated in sera from IM patients and matched healthy controls using the complement fixation test (CFT) and the haemagglutination inhibition test. Except for herpes simplex virus and cytomegalovirus, the IM sera had significantly higher arithmetical and geometrical mean antibody titres and showed in most cases higher antibody prevalences in the CFT. The titre rise was most pronounced for rubella and measles antibodies, between 2- and 3-fold. There were no cases of very high titres occasionally seen in IM. The IM sera had higher total IgG serum levels than the controls, 17.27 g/l and 11.8 g/l, respectively (P < 0.001). The present data show that in addition to previously reported high levels of some autoantibodies and of heterophilic antibodies, there is a more general increase in IgG antibodies to commonly occurring viruses. This increase is most likely due to the polyclonal activation of B-lymphocytes following the binding of EBV to the complement receptor CR2 (CD21). When due consideration is given to the possible occasional occurrence of a false positive rubella IgM test, the raised antibody-titres will most likely not interfere with routine diagnostics.

Relatives' locus of control and expressed emotion in schizophrenia and related psychoses.

OBJECTIVES: Knowledge of what predicts relatives' expressed emotion (EE) may contribute to improved family work in schizophrenia. In the present study we examined locus of control (LOC) beliefs as determinants of EE components. DESIGN: This study is observational, prospective and partly cross-sectional, partly longitudinal (stability of LOC). METHODS: In a Norwegian sample of 47 recently hospitalized patients (schizophrenia or schizophreniform disorder) and 70 relatives, the relatives' EE was assessed by the Camberwell Family Interview and LOC by Levenson's Internality, Powerful Others and Chance scales. RESULTS: Confirmatory multiple regression analyses showed that Chance LOC was positively related to emotional overinvolvement (p < .005). Powerful Others LOC, especially 'wish to ingratiate' items, were positively linked to criticism and, among workers/lower grade employees only, to emotional overinvolvement. Internal LOC was not linked to any EE scale. CONCLUSIONS: This study indicates that LOC beliefs may be determinants of emotional overinvolvement and criticism, and should be taken into account in family work that aims at modifying relatives' EE.

[Hepatitis B in Wallis: results of a seroepidemiological survey]. / L'hépatite B a Wallis: résultats d'une enquête séroépidémiologique.

A sero-epidemiological survey was conducted on Wallis Island, in the South Pacific, from July 1988 to May 1989. A random sample from the general population was examined. 672 sera were tested for HBs antigen and anti-HBc antibody. Analysis of the data showed that there was little, if any, transmission from mother to newborn; serological markers seemed to be acquired during the first years of life, before the age of 15 years. After 15 years, seropositivity rate is stabilized at 85% for one and/or the other of the two markers. The seropositivity rate is 39% for the HBs antigen alone. A protocol to vaccinate infants less than one year is proposed.

[Porocephalosis, a little known parasitosis, literature review and a Congolese case report]. / La porocéphalose, parasitose méconnue, revue de la littérature à propos d'un cas congolais.

The authors describe another case of symptomatic porocephalosis in a 59-year-old man from the Congo and review recent epidemiologic, clinical, and laboratory data from the literature concerning pentastomiasis in man. There are a variety of modes of transmission to man, parasitic dead end, and sites of infection. A perusal of symptomatic cases reported since 1970 confirms that complications are mainly associated with uncalcified nymphal forms. This poses a diagnostic problem since clinical and laboratory findings associated with young forms in non-specific. When feasible, surgical resection of infested tissue allows diagnosis and treatment. Many questions remain unanswered concerning the incidence of pentastomiasis in endemic areas, its physiopathology, and its relationship with cirrhosis and liver cancer in the tropics. New diagnostic techniques (serologic tests, ultrasonography, CT-scan) may help to resolve these issues.

Costs of vaccine delivery in the Gambia before and after, pentavalent and pneumococcal conjugate vaccine introductions.

BACKGROUND: The Gambia introduced seven-valent pneumococcal conjugate vaccine (PCV) in August 2009 and switched to 13-valent PCV in April 2011. In April 2009 monovalent hepatitis B and combined Diphtheria-Tetanus-Pertussis and Haemophilus influenzae type b vaccines were transitioned to a combined pentavalent vaccine. The current schedule offers three doses of PCV and pentavalent, and continues to give children monovalent hepatitis B vaccine at birth. We estimated the overall costs of the Gambian immunisation programme and the incremental costs of introducing pentavalent and the seven-valent PCV. METHODS: Twenty health facilities out of a total of 56 were surveyed. Data collected included number of vaccine doses delivered, staff time spent on vaccine delivery, distance travelled to collect vaccines, and cold chain expansion due to new vaccine introduction. National level data were collected from key informant interviews. Annualised costs were calculated in 2009 US$. RESULTS: With a PCV price of US$7 per dose, the incremental costs of introducing PCV was US$1.6 million, equivalent to US$25 per fully immunised child, with systems costs accounting for US$1.90. The switch to pentavalent vaccine resulted in cost savings of US$0.45 per fully immunised child. Total annual costs increased by 45% after the introduction of the new vaccines, amounting to US$ 3.0 million, or US$45 per fully immunised child. CONCLUSION: Vaccine prices were the most important determinant of total incremental costs and cold chain expansion the biggest cost component of systems costs.

Does guilt proneness predict acute and long-term distress in relatives of patients with schizophrenia?

OBJECTIVE: The aim of the study was to improve our understanding of guilt proneness as predictor of acute and long-term stress responses in relatives of acutely admitted patients. METHOD: Forty-nine relatives in close contact with 36 patients suffering from schizophrenia DSM-III-R, completed Hostility Guilt (HG) and Guilt Conscience (GC) scales (Revised Mosher Guilt Inventory), and Levenson's Locus of Control Scale (LOC) at the patient's admission to hospital, and the General Health Questionnaire (GHQ) at the patient's admission and at 9 months after discharge. RESULTS: Acute distress (GHQ) was positively related to HG, but not when controlling for LOC. GC was positively associated with acute and long-term distress, GHQ-depression and coping-failure, and long-term GHQ-anxiety. When controlling for LOC, GC was still positively related to long-term distress. HG, GC and LOC explained 32% variance of GHQ at 9 months. CONCLUSION: GC seems to be an important predictor of long-term distress in relatives.

Down-regulation of cyclin A gene expression upon genotoxic stress correlates with reduced binding of free E2F to the promoter.

Treatment of mammalian cells by DNA-damaging agents leads to various cellular responses. At sufficiently high dosage, cisplatin blocks cell proliferation and finally kills cells; this effect is the basis for its widespread use as an anticancer drug. Cisplatin-treated cells arrest in the G1 phase of the cell cycle, most likely due to a signal generated by the stabilization of p53 and the subsequent induction of p21WAF-1/Cip1. We show here that cisplatin-treated mammalian cells accumulate normal levels of cyclin D1 and cyclin E but fail to produce cyclin A. The block to cyclin A gene expression occurs at the level of transcription and is mediated by an E2F binding site in the cyclin A promoter. It is shown here that, upon cisplatin treatment, transcriptionally active free E2F becomes limiting, coincident with the accumulation of hypophosphorylated species of the retinoblastoma protein family. Immunoprecipitation experiments suggest that the loss of free E2F results, at least in part, from the sequestration of E2F-4/DP-1 heterodimers by p107. A role for the kinase inhibitor p21WAF-1/Cip1 in repression of the cyclin A promoter is supported by our finding that ectopic expression of p21WAF-1/Cip1 is sufficient to inhibit transcription from the cyclin A gene, dependent on the E2F site. The data establish the E2F site in the human cyclin A promoter as a key target for the signaling pathway leading to G1 arrest in response to DNA damage by cisplatin and potentially other genotoxic agents.

Retinoic acid-mediated repression of human papillomavirus 18 transcription and different ligand regulation of the retinoic acid receptor beta gene in non-tumorigenic and tumorigenic HeLa hybrid cells.

Human papillomavirus type 18 (HPV18) belongs to the group of genital papillomaviruses involved in the development of cervical carcinomas. Since retinoic acid (RA) is a key regulator of epithelial cell differentiation and a growth inhibitor in vitro of HPV18-positive HeLa cervical carcinoma cells, we have used HeLa and HeLa hybrid cells in order to analyse the effects of RA on expression of the HPV18 E6 and E7 oncogenes and of the cellular RA receptor genes RAR-beta and -gamma. We show here that RA down-regulates HPV18 mRNA levels apparently due to transcriptional repression. Transient cotransfection assays indicated that RARs negatively regulate the HPV18 upstream regulatory region and that the central enhancer can confer RA-dependent repression on a heterologous promoter. RA treatment resulted in induction of RAR-beta mRNA levels in non-tumorigenic HeLa hybrid cells, but not in tumorigenic hybrid segregants nor in HeLa cells. No alterations of the RAR-beta gene or of the HeLa RAR-beta promoter could be revealed by Southern and DNA sequence analysis, respectively. As determined by transient transfection assays, however, the RAR-beta control region was activated by RA more strongly in non-tumorigenic hybrid cells than in HeLa cells, thus indicating differences in trans-acting regulatory factors. Our data suggest that the RARs are potential negative regulators of HPV18 E6 and E7 gene expression, and that dysregulation of the RAR-beta gene either causatively contributes to or is an indicator of tumorigenicity in HeLa and HeLa hybrid cells.

Relatives' distress and patients' symptoms and behaviours: a prospective study of patients with schizophrenia and their relatives.

OBJECTIVE: The aim of this study is to explore the relationship between relatives' distress and patients' symptoms and behaviours. METHOD: Fifty relatives in close contact with 36 patients with schizophrenia DSM-III-R filled in the General Health Questionnaire (GHQ) and the Perceived Family Burden Scale (PFBS) at the patient's hospital admission, 4.5 and 9 months post-discharge. The patients were assessed by means of the Positive and Negative Syndrome Scale (PANSS). RESULTS: The PFBS anxiety-depression cluster was at all three assessments positively correlated with relative's distress (GHQ), not with PANSS anxiety and depression measurements. In multiple regression analysis PFBS, but not PANSS, was related to relatives' distress. CONCLUSION: Relatives' distress was related to their reports of problematic patient behaviours, especially anxiety-depressive behaviour, not to symptoms as measured by clinical interviews. High distress is related to high expressed emotion, suggesting that relatives' report of patient's behaviour should be addressed to improve patient's outcome.

Inter-rater reliability of expressed emotion ratings based on the Camberwell Family Interview.

High expressed emotion in relatives has been shown to predict a poorer outcome in a range of disorders and cultures. However, variation in predictive power is considerable, and this could partly be due to low inter-rater reliability. Sixty-nine relatives of 47 acutely admitted schizophrenic patients were interviewed using the Camberwell Family Interview. Audiotapes were assessed by pairs of raters drawn from a group of seven approved raters. Inter-rater reliability was good for criticism, hostility, emotional over-involvement (as a six level scale) and expressed emotion index (EOI cut-off score 2-3); and it was fair, but unsatisfactory, for emotional over-involvement (binary scales), warmth, positive remarks and expressed emotion (EOI cut-off score 3-4). These findings suggest that the warmth scale and the dichotomized versions of the EOI scale should be used with caution. The influence of warmth on the outcome in schizophrenia may have been underestimated because of low reliability.

What predicts the course of expressed emotion in relatives of patients with schizophrenia or related psychoses?

The expressed emotion (EE) index may not be as stable as it was once believed to be. The aim of this study was to identify variables associated with spontaneous change from low to high and from high to low levels of EE and EE subscales--critical comments (CC), hostility (H), emotional overinvolvement (EOI). Using a longitudinal, prospective study design, of 59 relatives having at least weekly face-to-face contact with 40 patients with an acute episode or relapse into schizophrenia (DSM-III-R) were interviewed by means of the Camberwell Family Interview (CFI) at admission and at 4 1/2 months after discharge. The results showed that high-high or unstable levels of CC, H or EE were associated with the patient not working or studying prior to admission. Relatives with low-high and high-high EOI patterns had more weekly face-to-face contact with the patient prior to admission than relatives with a low-low EOI pattern. Patients whose relatives had low-high CC and EE patterns were less ill at admission than patients whose relatives had low-low patterns. Higher perceived family burden was associated with, at admission, an unstable pattern of CC, and at follow-up, high-high EOI or EE patterns rather than low-low patterns. Our study suggests that it is possible to identify which relatives will have a stable and which a changing EE level, allowing for more focused intervention.

Criticism and hostility in relatives of patients with schizophrenia or related psychoses: demographic and clinical predictors.

Relatives' criticism and hostility are important risk factors for relapse in schizophrenia. In order to explain these attitudes, we examined a Norwegian sample of 47 recently hospitalized patients (with schizophrenia or related psychoses) and 72 relatives. Relatives' expressed emotion was assessed by means of the Camberwell Family Interview. Demographic and clinical data were used as predictor variables in confirmatory regression analyses. The most robust predictors of high levels of criticism were, on the part of the patient, lack of paid employment, more than 3 previous hospital admissions, more troublesome behaviours reported by relatives, especially anxiety/depression, and better cognitive functioning at admission. Robust predictors of hostility were lack of employment and more than 3 previous hospitalizations. Interventions to reduce criticism should include employing patients and working with relatives' unrealistic expectations.

Relatives' emotional warmth towards patients with schizophrenia or related psychoses: demographic and clinical predictors.

Despite the importance of relatives' emotional warmth for outcome in schizophrenia, no studies to date have addressed demographic and clinical predictors of warmth. We examined a Norwegian sample of 47 recently hospitalized patients (with schizophrenia or schizophreniform disorder) and 72 key relatives. Relatives' emotional warmth was assessed by means of the Camberwell Family Interview. Regression analyses showed that no substance abuse (especially amphetamines), better premorbid adjustment (12-15 years), a chronic social security status, and the relative not being a parent were the strongest predictors of emotional warmth. Emotional warmth was not related to patients' symptoms.

Guilt proneness and expressed emotion in relatives of patients with schizophrenia or related psychoses.

OBJECTIVE: Knowledge of what predicts relatives' expressed emotion (EE) may contribute to improved family work in schizophrenia. In the present study we examined guilt proneness as a determinant of EE components. METHOD: In a Norwegian sample of 46 recently hospitalized patients (schizophrenia or schizophreniform disorder) and 69 relatives, relatives' expressed emotion was assessed by means of the Camberwell Family Interview, and guilt proneness by means of the Revised Mosher Guilt Inventory. (RMGI). RESULTS: Confirmatory multiple regression analyses showed that hostility-guilt (RMGI) was negatively related to high levels of criticism and hostility and, for men, positively related to emotional overinvolvement. There was a strong positive relationship between relatives' guilty conscience (RMGI) and emotional overinvolvement if the patient had a diagnosis of schizophrenia. CONCLUSIONS: Our analyses indicate that relatives' guilt proneness may be a determinant of their criticism, hostility and emotional overinvolvement towards a schizophrenic family member. This personality trait should be taken into account in family work which aims at modifying relatives' expressed emotion.

Emotional overinvolvement in parents of patients with schizophrenia or related psychosis: demographic and clinical predictors.

BACKGROUND: Parental emotional overinvolvement (EOI) may entail a worse outcome in schizophrenia. In the present study we examined demographic and clinical predictors of EOI. METHOD: The predictors were examined in a Norwegian sample of 41 recently admitted patients (schizophrenia or schizophreniform disorder) and 66 parents. Parents' expressed emotion was assessed by the Camberwell Family Interview. RESULTS: Regression analyses showed that higher EOI was significantly related, on the part of the parent, to being a mother, single, spending more time with the patient; and, on the part of the patient, to no substance misuse, more anxiety-depression, and less uncritical and aggressive behaviour. EOI was not linked to previous hospital admissions. CONCLUSION: Our analyses indicate that characteristics of the parent and of the parent-patient dyad seem to be the most important determinants of EOI. EOI is probably not linked to psychotic relapse, but rather to affective disturbances in the patient.
