Insight into mental illness and child maltreatment risk among mothers with major psychiatric disorders

OBJECTIVES

This study examined the relationship between insight into mental illness and current child maltreatment risk among mothers who had a major psychiatric disorder and who had lost custody of a child because of abuse, neglect, or having placed the child at risk of harm. Specifically, a measure of insight was examined in relation to systematically observed parenting behaviors known to be correlated with past child maltreatment and in relation to a comprehensive clinical determination of risk.

METHODS

Forty-four mothers who had a major psychiatric disorder were independently rated for their insight into their illness, the quality of mother-child interaction, and the overall clinical risk of maltreatment.

RESULTS

Better insight into mental illness was associated with more sensitive mothering behavior and with lower assessed clinical risk of maltreatment. The association remained when mothers with current psychotic symptoms were excluded from the analyses. Better insight did not appear to be associated with past psychotic symptoms, maternal psychiatric diagnosis, or the mother's level of education.

CONCLUSIONS

Insight into mental illness may function as a protective factor that influences the risk of child maltreatment in mothers with mental illness. Measures of insight could be usefully incorporated into comprehensive parenting assessments for mothers with psychiatric disorders.

Predicting type of psychiatric disorder from Strengths and Difficulties Questionnaire (SDQ) scores in child mental health clinics in London and Dhaka

A computerised algorithm was developed to predict child psychiatric diagnoses on the basis of the symptom and impact scores derived from Strengths and Difficulties Questionnaires (SDQs) completed by parents, teachers and young people. The predictive algorithm generates "unlikely", "possible" or "probable" ratings for four broad categories of disorder, namely conduct disorders, emotional disorders, hyperactivity disorders, and any psychiatric disorder. The algorithm was applied to patients attending child mental health clinics in Britain (N = 101) and Bangladesh (N = 89). The level of chance-corrected agreement between SDQ prediction and an independent clinical diagnosis was substantial and highly significant (Kendall's tau b between 0.49 and 0.73; p < 0.001). A "probable" SDQ prediction for any given disorder correctly identified 81-91% of the children who definitely had that clinical diagnosis. There were more false positives than false negatives, i.e. the SDQ categories were over-inclusive. The algorithm appears to be sufficiently accurate and robust to be of practical value in planning the assessment of new referrals to a child mental health service.

Tumor angiogenesis in chronic pancreatitis and pancreatic adenocarcinoma: impact of K-ras mutations

Chronic pancreatitis (CP) is one condition in which epidemiologic studies have demonstrated a definite association with pancreatic adenocarcinoma (PAC). The pathophysiologic and molecular events that either predispose to the development of, or potentiate the growth of, PAC are unknown. Mutation of the codon 12 K-ras gene is one genetic aberration commonly associated with development of PAC. Tumor angiogenesis, or microvascular proliferation of new capillaries, is another pathophysiologic alteration associated with PAC. Although activated ras oncogenes modulate tumor angiogenesis/neovascularization in some tumors, the importance of tumor angiogenesis and the role of K-ras mutation in regulating angiogenesis in CP and PAC are unknown. The aim of this study was to elucidate the relationship between angiogenesis and K-ras mutations in CP and PAC. Tumor angiogenesis and K-ras mutations were evaluated in resected specimens from 25 CP (23 CP plus two CP with PAC) and 16 PAC patients. Tumor angiogenesis was determined using immunohistochemistry of factor VIII-related antigen (FVIIIRAg) and ras mutations were identified by enriched-nested polymerase chain reaction. The mean number of FVIIIRAg-positive blood vessels was significantly (p < 0.005) higher in PAC (23.0 +/- 7.5), CP with a mutant K-ras genome (17.7 +/- 2.8) and CP with a normal K-ras genome (6.5 +/- 3.8), compared to unaffected areas. Codon 12 K-ras mutations were detected in three of 25 CP specimens (12%) and in 15 of 16 PAC specimens (94%). In CP patients with mutant K-ras in their genome, microvessel density was significantly (p < 0.01) elevated, compared to patients with a normal K-ras genome. Statistical analyses (Spearman rank-difference correlation coefficient, Student t test, and chi2 analysis) indicated a significant association between codon 12 K-ras mutations and tumor angiogenesis in both CP and PAC. This study demonstrates a significant association between angiogenesis and K-ras mutation in both PAC and CP. At a minimum, K-ras mutation is associated with the events that increase angiogenesis and it may potentiate or promote tumor angiogenesis.

An open clinical trial with clozapine in treatment-resistant schizophrenics

In an open trial, drug-resistant schizophrenics were treated with clozapine for sixteen weeks. The patients were rated on BPRS, PANSS, Side effects scale and Global Impression Scale at weeks 0. 9 and 16. A battery of base-line investigations were done, and hemogram was repeated at weekly intervals. Of the total 29 patient included. 25 completed the trial. The patients showed significant improvement on both BPRS and PANSS, although the improvement was more in initial weeks than between 9 and 16 weeks. The most common side effects observed were sedation, hypersalivation and tachycardia. Issues of response of clozapine on negative symptoms and a longer duration of the drug therapy are discussed.
