Empirically validated treatments and child clinical interventions - Comment

This commentary argues that empirically validated treatments for child and youth behaviour and emotional difficulties are available, but they are relatively inaccessible to the vast majority of Australian children and their families. Although effective interventions have been developed, few children receive these services. There are many children who have identifiable problems or who are at increased risk for psychosocial problems whose needs have not been adequately addressed by either the research or the professional community. These include children in rural and remote areas, Aboriginal and Tones Strait Islander children, children of migrants, and children with chronic physical illnesses. A comprehensive, preventively focused clinical science of prevention is needed to improve the reach and impact of psychological services for children.

Distribution of HDL-cholesterol and non-HDL-cholesterol in Brazilian children and adolescents - The Floripa study

Background and aims: HDL-cholesterol (HDL-C) and non-HDL-cholesterol (nHDL-C) are involved in atherosclerosis. The aim of this study was to determine the distribution of HDL-C and nHDL-C and its association with cardiovascular and socio-cultural variables in a pediatric Brazilian sample. Methods and results: Children and adolescents from Florianopolis were randomly selected and a structured questionnaire was administered, a physical examination was performed and a blood sample was collected. Enzymatic and Direct methods in vitro were used to determine the total cholesterol and HDL-cholesterol levels. The associations among HDL-C and nHDL-C and the described variables were tested by odds ratio and logistic regression. A total of 1009 individuals were examined. Based on the Brazilian criteria, 23% were classified with low levels of HDL-C and 25% with high levels of non-HDL-C. After multivariate analysis there were significant associations among low HDL-C and high C-reactive protein (OR, 3.3; 95% CI, 2.1-5.2), paternal tobacco use (OR, 1.5; 95% CI, 1.1-2.1), and high triceps-to-subscapular index (OR, 1.5; 95% CI, 1.1-2.2). There were also significant associations among high nHDL-C and high waist circumference (OR, 1.95; 95% CI, 1.16-3.29), black skin color (OR, 1.78; 95% CI, 1.06-3.06), and high income (OR, 1.48; 95% CI, 1.09-2.02). Conclusions: In this sample, low levels of HDL-C were associated with other clinical variables such as a centripetal fat pattern and C-reactive protein, and n-HDL-C was associated with abdominal obesity, skin color and economic class.

Ethanol feeding enhances inflammatory cytokine expression in lipopolysaccharide-induced hepatitis

Elevated concentrations of plasma tumour necrosis factor (TNF)-alpha, interleukin (IL)-1 and IL-6 have been detected in patients with alcoholic hepatitis and have been implicated in the pathogenesis of hepatocyte necrosis. The present study used a rat model to conduct a detailed histological and biochemical examination of the expression of various pro-inflammatory cytokines and associated liver pathology in ethanol-potentiated lipopolysaccharide (LPS)-induced liver injury. Male Wistar rats were pair-fed either the control or ethanol-containing (36% of caloric intake as ethanol) form of the Lieber-DeCarli liquid diet for 6 weeks. Liver injury was induced by the i.v. injection of LPS (1 mu g/g bodyweight), with animals being killed at O, 1, 3, 6, 12 and 24 h after injection. At the later time points, plasma transaminase and transpeptidase activities were significantly elevated in ethanol-fed LPS-treated rats compared with control-fed LPS-treated animals. At these times after LPS treatment, hepatocytes in ethanol-fed animals displayed fatty change and necrosis with an associated neutrophil polymorph infiltrate. Time course analysis revealed that plasma TNF-alpha (1-3 h post-LPS) and IL-6 (3 h post-LPS) bioactivity was significantly elevated in ethanol-fed compared with control-fed animals. No difference was seen in plasma IL-1 alpha concentration (maximal in both groups 6 h post-LPS). The expression of TNF-alpha, IL-1 alpha, IL-1 beta and IL-6 mRNA were elevated between 1 and 6 h post-LPS in the livers of both control and ethanol-fed rats. However, ethanol-fed LPS-treated animals exhibited significantly higher maximal expression of IL-1 and IL-6 mRNA. Comparison of the appearance of cytokine mRNA and plasma bioactivity indicated an effect of ethanol feeding on post-transcriptional processing and/or the kinetics of the circulating cytokines. Elevated levels of both hepatic cytokine mRNA expression and the preceding plasma cytokines are presumably a necessary prerequisite for hepatic injury seen in this model and, therefore, possibly for the damage seen in human alcoholics. Further studies using this model may lead to significant advances in our understanding of the pathogenic mechanisms of alcoholic liver disease in humans.

Oral sensorimotor function for feeding in patients with tetanus

Tetanus still remains a significant health problem in developing countries; it is a serious disease with a high mortality rate. The purpose of this study was to characterize the oral sensorimotor function for feeding in patients with tetanus. Thirteen patients clinically diagnosed with tetanus and admitted to an intensive care unit between December of 2005 and May of 2007 underwent a screening too) for dysphagia, involving the assessment of clinical features and 2 swallowing tests. Results indicate that the oral sensorimotor function for feeding in these patients is severely compromised, with the exception for the clinical feature of palate elevation and performance in the saliva swallowing test. The factor analysis indicated that the evaluation of tongue movement change in the oromotor examination is important in predicting alterations of cough/voice in the water swallowing test, thus suggesting that oral feeding might be unsafe. When looking at developing countries, the prolonged intensive medical and nursing care required by many patients with tetanus places extra demands on an already stretched healthcare budget. Intervention by a speech pathologist could mean that time in the ICU would be reduced as well as the number of re-admissions due to complications. (C) 2009 Elsevier B.V. All rights reserved.

Tube feeding with a diabetes-specific feed for 12 weeks improves glycaemic control in type 2 diabetes patients

Background and aims: Assess longer-term (12 weeks) effects of a diabetes-specific feed on postprandial glucose response, glycaemic control (HbA1c), lipid profile, (pre)-albumin, clinical course and tolerance in diabetic patients. Methods: In this randomized, controlled, double-blind, parallel group study 25 type 2 diabetic patients on tube feeding were included. Patients received a soy-protein based, multi-fibre diabetes-specific feed or isocaloric, fibre-containing standard feed for 12 weeks, while continuing on their anti-diabetic medication. At the beginning, after 6 and 12 weeks, several (glycaemic) parameters were assessed. Results: The postprandial glucose response (iAUC) to the diabetes-specific feed was lower at the 1st assessment compared with the standard feed (p = 0.008) and this difference did not change over time. HbA1c decreased over time in the diabetes-specific and not in the standard feed group (treatment*time:p = 0.034): 6.9 +/- 0.3% (mean +/- SEM) at baseline vs. 6.2 +/- 0.4% at 12 weeks in the diabetes-specific group compared to 7.9 +/- 0.3% to 8.7 +/- 0.4% in the standard feed group. No significant treatment*time effect was found for fasting glucose, insulin, (pre-) albumin or lipid profile, except for increase of HDL in the diabetes-specific group. Conclusions: The diabetes-specific feed studied significantly improved longer-term glycaemic control in diabetic patients. This was achieved in addition to on-going anti-diabetic medication and may affect clinical outcome. (C) 2009 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Translation to Portuguese and Validation of the Douleur Neuropathique 4 Questionnaire

The Douleur Neuropathique 4 (DN4) questionnaire was developed by the French Neuropathic Pain Group and is a simple and objective tool, with the ability to distinguish nociceptive from neuropathic pain. The purpose of this work was to validate the DN4 questionnaire in the Portuguese language in order to allow its use in clinical and research settings. A double-blind, accuracy study was conducted, consisting of translation, back-translation, literal evaluation, semantic equivalence, and communication with the target population. The Portuguese version of the questionnaire was applied in a sample of 101 patients with neuropathic (N = 42) or nociceptive pain (N = 59), ranked according to medical diagnosis. The reproducibility, reliability and validity of the instrument were analyzed, and showed a high diagnostic power for this version of the DN4 questionnaire. The Portuguese version of the DN4 questionnaire presented good validity and reliability, allowing it to identify neuropathic pain and neuropathic characteristics of mixed pain syndromes. Perspective: This article presents the first validated neuropathic pain questionnaire in the Portuguese language and represents a useful tool in the assessment of neuropathic pain both in the clinical setting and in population-based studies. The sensible and quick format of this instrument are key factors that will contribute to its widespread use, permitting a true recognition of patients with neuropathic pain.

Cross-cultural adaptation and validation of a Quality of Life questionnaire: The Nasal Obstruction Symptom Evaluation questionnaire

Background:The Nasal Obstruction Symptom Evaluation (NOSE) instrument is a disease-specific questionnaire for assessing the outcome of an intervention in nasal obstruction in trials. This instrument is only available in the English language and cross-culturally valid questionnaires are very important for all research, including nasal obstruction. The aim of the current study was to reproduce the cross-cultural adaptation process for the NOSE questionnaire in the Portuguese language (NOSE-p). Methodology: Cross-cultural adaptation and validation of the instrument were divided into two stages. Stage I involved four bilingual professionals, an expert committee and the author of the original instrument. In Stage 2, the NOSE-p was tested on 33 patients undergoing septoplasty for internal consistency, test-retest reliability, construct validity. discriminant validity, criterion validity, and response sensitivity. Results: The cross-cultural adaptation process was completed and the NOSE-p was demonstrated to be a valid instrument with satisfactory construct validity. It showed an adequate internal consistency reliability and adequate test-retest reliability. It could discriminate between patients with and without nasal obstruction and it has a high response sensitivity to change. Conclusions: The cross-cultural adaptation and validation process demonstrated to be valid and the NOSE-p proved to be applicable in Brazil.

Passive Acquisition of Protective Antibodies Reactive with Bordetella pertussis in Newborns via Placental Transfer and Breast-feeding

Although acquisition of anti-pertussis antibodies by the newborn via placental transfer has been demonstrated, a subsequent recrudescence of pertussis infection is often observed, particularly in infants. The present study investigated the passive transfer of anti-pertussis IgG and IgA antibodies to term newborns and their ability to neutralize bacterial pathogenicity in an in vivo experimental model using mice intracerebrally challenged with viable Bordetella pertussis. Forty paired samples of maternal/umbilical cord sera and colostrum were obtained. Anti-pertussis antibodies were analysed by immunoenzymatic assay and by Immunoblotting. Antibody neutralizing ability was assessed through intracerebral B. pertussis challenges in mice. Anti-pertussis IgG titres were equivalent in both maternal and newborn sera (medians = 1:225 and 1:265), with a transfer rate of 118%. The colostrum samples had variable specific IgA titres (median = 1:74). The immunoblotting assays demonstrated identical recognition profiles of paired maternal and newborn serum pools but different bacterial recognition intensities by colostrum pools. In the animal model, significant differences were always observed when the serum and colostrum samples and pools were compared with the positive control (P < 0.05). Unlike samples with lower anti-pertussis titres, samples with high titres showed protective capacities above 50%. Pertussis-absorbed serum and colostrum pools protected 30% of mice and purified IgG antibodies protected 65%. Both pooled and single-sample protective abilities were correlated with antibody titres (P < 0.01). Our data demonstrated the effectiveness of anti-pertussis antibodies in bacterial pathogenesis neutralization, emphasizing the importance of placental transfer and breast-feeding in protecting infants against respiratory infections caused by Bordetella pertussis.

Exclusive Breastfeeding in Southern Brazil: Prevalence and Associated Factors

Background: Worldwide strategies have been conducted in order to guarantee longer periods of exclusive breastfeeding for most children, especially those from developing countries. The evaluation of infant feeding practices and the identification of weaning risk factors are essential for public health policy planning. Methods: This cross-sectional study was carried out in Joinville, the biggest city of Santa Catarina State in the southern Brazilian region. The caregivers of children under 1 year of age were systematically selected for interview in previously drawn immunization units during the 2005 National Vaccination Campaign. A structured questionnaire was applied for collection of infant, maternal, and healthcare variables. A 24-hour food recall survey was included in order to evaluate infant feeding practices. Descriptive statistic analysis on breastfeeding prevalence and Poisson regression analysis of risk factors for discontinuing exclusive breastfeeding for infants up to 6 months of age were performed. Results: Caregivers of 1,470 infants were interviewed. The feeding inquiry showed an overall rate of breastfeeding of 72.5% and a frequency of exclusive breastfeeding of 43.7% and 53.9% among infants younger than 6 and 4 months of age, respectively. The findings associated with the interruption of exclusive breastfeeding for infants up to 6 months were: higher infant age (P < 0.001), pacifier use (P < 0.001), and lower maternal educational level (P = 0.013). Conclusions: In developing countries, specific strategies must be created for the delivery of information about breastfeeding and the effect of pacifier use, especially for less educated women.

CHOREA IN A CHILD WITH CHURG-STRAUSS SYNDROME

Introduction: Churg-Strauss syndrome (CSS) is a systemic granulomatous vasculitis rarely described in children, particularly associated with neurological involvement, exceptionally chorea. To our knowledge there are only 35 children and adolescent patients with CSS described in the literature. During a 25-year period 5283 patients were followed up at the Pediatric Rheumatology Unit of our University Hospital and only one (0.02%) presented CSS. Case report: A 7-year-old boy suffered from severe asthma, eosinophilia, history of allergy, recurrent non-fixed pulmonary infiltrates, several nodular lesions in both lungs and maxillary sinusitis. Transthoracic biopsy of the right lung revealed necrotizing extravascular eosinophilic infiltrates and the diagnosis of CSS was established. During the follow-up he had persistent vasculitis skin lesions and hemichorea. Despite the treatment with immunosuppressive drugs and intravenous immunoglobulin, he died because of pulmonary abscess and sepsis. Discussion: A rare case of CSS with chorea was reported, reinforcing the possibility of this disease in children with asthma, allergic rhinitis, hypereosinophilia and cutaneous vasculitis.

Child psychiatry takes to the streets: A developmental partnership between a university institute and children and adolescents from the streets of Sao Paulo, Brazil

Objective: High levels of domestic violence, mental illness, and alienation from authorities are associated with high incidence of children/adolescents living on the streets in low and middle income countries. The Equilibrium Project (Programa Equilibrio) was created to facilitate social reintegration through a virtual partnership between an academic psychiatric institute and highly vulnerable children and adolescents living on the streets, in group shelter with supervision, and in other high risk situations. Methods: Descriptive presentation of qualitative data and analysis of preliminary empirical data collected over a 24-month period. Results: Dialogue between academic professionals, street children, and city officials shaped The Equilibrium Project over the last 2 years. The program has progressively moved from a professional clinic setting to a community-based but protected activity center with recreational and professional services and an emphasis on linkage with social service agencies, city government and law enforcement officials in an academic research context. A total of 351 patients have been served of whom virtually all were neglected by their parents, 58.4% report physical or sexual abuse, 88.89% have been diagnosed with a psychiatric disorder, 40.4% drug use. After 2 years of operation, 63.5% (n = 223) successfully completed or continue in treatment and 34.8% (n = 122) were reunited with their families. Conclusions and Practice implications: Program development guided by consumer input led to a successful program offering professional services in a protected community setting that facilitates social reintegration by providing ""go between"" services integrating relationships between alienated consumers and formal psychiatric, pediatric, social service, and criminal justice systems.

Validity of the self reporting questionnaire-20 in epidemiological studies with older adults

This study examined the validity of the self-reporting questionnaire (SRQ-20) in a population-based survey with older adults in Sao Paulo, Brazil. The study sample consisted of 2,008 individuals aged 65 years or more who were living in an economically disadvantaged area of the city. The geriatric mental state (GMS) was used as the gold standard for the assessment of common mental disorders (CMD). The optimal SRQ-20 threshold for case definition was 4/5 (sensitivity = 76.1%, specificity = 74.6%, area under ROC curve = 0.82). Women, older participants and those with lower income were more likely to be misclassified by the questionnaire. The inclusion of older persons with dementia or psychosis did not change the ability of the SRQ-20 to identify cases of CMD. The SRQ-20 may be a useful instrument to be used in large epidemiological studies in resource-poor settings for the identification of cases of depression and anxiety in later life. The performance of the SRQ-20 among older adults was similar to that observed with the adult population in Brazil.

Drug consumption among sexual offenders against females

This article aims to evaluate the role of drug consumption among sexual offenders against females. Three groups of participants (N = 133) comprising sexual offenders against girls, pubertal females, and women were examined with reference to history of drug and/or alcohol use, impulsivity level, sexual addiction, and recidivism risk. Sexual offenders against women were found to have significantly more difficulties with drug use, higher impulsivity level, and to be younger than the sexual offenders against girls and pubertal females. The combination of drug consumption and higher level of impulsivity may contribute to sexual aggression against adult females.
