Spanish Version of the Children's Somatization Inventory: Factorial Structure and Psychometric Properties in a Community Sample

Background

The Children's Somatization Inventory (CSI) has proved to be a suitable measure to assess somatic symptoms in pediatric patients, but additional research was needed to evaluate its psychometric properties in community populations.

Purpose

The objective of the present study was to examine psychometric properties and factorial structure of the instrument among a nonclinical sample of Spanish children.

Method

The 24-item version of the CSI and two self-report measures of anxiety and depression were administered to 1,111 Spanish children aged 8 to 12.

Results

Exploratory analysis suggested a factorial structure composed of three factors: pseudoneurologic symptoms, gastrointestinal symptoms, and pain. Due to confirmatory analysis indicating a poor fit for the three-factor model, two alternative models were tested. A six-item single factor identified in a previous study with an American community sample showed the best fit (RMSEA?=?0.04; GFI?=?0.99; AGFI?=?0.98; CFI?=?0.98; χ²/gl?=?2.71). The internal consistency for the six-item version was acceptable (ω?=?.71), and the construct validity with anxiety (r?=?.53) and depression (r?=?.38) measures was adequate.

Conclusion

The six-item version of the CSI demonstrated to be a reliable measure for assessing somatization symptoms in Spanish children.     

Neuroticism and impulsivity: Their hierarchical organization in the personality characterization of drug-dependent patients from a decision tree learning perspective

Objective

Neuroticism and impulsivity are the personality variables most consistently associated with drug-dependent patients. To date, no data mining procedures have been applied to explore the differential role of personality variables in this population.

Methods

The personality profile of 336 drug-dependent patients was compared with that of a sample of community participants in the context of a decision tree learning approach using the Alternative Five Factor Model. The resulting discriminant model was cross-validated.

Results

Neuroticism and impulsivity were the most relevant variables in the resulting model, but their association appeared to be hierarchically organized. In the personality characterization of these patients, neuroticism became the main discriminant dimension, whereas impulsivity played a differential role, explained by means of an interaction effect. Decision tree learning models appear to be a heuristic theoretical and empirical approximation to the study of relevant variables, such as personality traits, in drug-dependency research.     

Health related quality of life changes in somatising patients after individual versus group cognitive behavioural therapy: A randomized clinical trial

Objective

To assess changes in health related quality of life after a cognitive behavioural program for patients diagnosed with abridged somatization disorder in primary care.

Method

A multicentre, randomized, parallel group, controlled trial was designed. 168 patients were recruited from 29 primary health care centres in Spain and were randomly assigned to one of the three study arms: treatment as usual improved with Smith's norms, individual cognitive behavioural treatment, and group cognitive behavioural treatment. Health-related quality of life was assessed using SF-36 Health Survey.

Results

Individual cognitive behavioural treatment achieves greater changes in health related quality of life than group cognitive behavioural therapy and treatment as usual. Improvement in health related quality of life was fully observed at 12 month, and partially at 6 months. The modality of intervention interacts with time in all dimensions except for Physical functioning and Vitality. Patients who received individual cognitive behavioural therapy treatment had better scores in Physical and Mental health summary measures at 12 month follow-up.

Conclusions

Individual cognitive behavioural treatment is the most effective way to improve health related quality of life in abridged somatization disorder patients, and its effects are sustained over time. Also, regardless of the type of intervention, physical functioning improves compared with treatment as usual.     

Electrocardiographic changes of ST-elevation myocardial infarction in patients with complete occlusion of the left main trunk without collateral circulation: Differential diagnosis and clinical considerations

Acute coronary syndromes due to involvement of the left main trunk usually present with subtotal occlusion and electrocardiographic pattern with predominant ST depression (non-ST-elevation myocardial infarction). The cases with complete occlusion frequently present an ST-elevation myocardial infarction pattern, but these patients usually die before reaching the hospital. We present a series of 7 patients with total left main trunk occlusion without collateral circulation showing ST-elevation myocardial infarction pattern. The electrocardiographic pattern is similar to left anterior descending coronary artery proximal occlusion to first septal and first diagonal but without ST elevation in V(1) and aVR because of left circumflex coronary artery compromise. In 4 (60%) of 7 of cases, there is also advanced right bundle-branch block plus superoanterior hemiblock. Despite severe clinical state at entrance (5/7 presented cardiac arrest/cardiogenic shock), 3 patients (43%) survived after percutaneous coronary intervention.     

Endobronchial metastases of anal canal carcinoma

Endobronchial metastases (EBM) secondary to extrapulmonary primary tumours are rare. The most common solid malignant tumours associated with EBM are breast, renal and colorectal carcinomas. This case report describes the first documented case of EBM from anal canal carcinoma. This neoplasm constitutes less than 1% of colorectal tumours. The clinical presentation of this entity is variable, being asymptomatic in more than 50% of cases. Generally, EBM are diagnosed in advanced stages and the survival after the diagnosis is poor. It is therefore an exceptional clinical manifestation in which bronchoscopy has an important role in the diagnosis and the treatment.     

Benefit from autologous stem cell transplantation in primary refractory myeloma? Different outcomes in progressive versus stable disease

Background

Several studies of autologous stem cell transplantation in primary refractory myeloma have produced encouraging results. However, the outcome of primary refractory patients with stable disease has not been analyzed separately from the outcome of patients with progressive disease.

Design and Methods

In the Spanish Myeloma Group 2000 trial, 80 patients with primary refractory myeloma (49 with stable disease and 31 with progressive disease), i.e. who were refractory to initial chemotherapy, were scheduled for tandem transplants (double autologous transplant or a single autologous transplant followed by an allogeneic transplant). Patients with primary refractory disease included those who never achieved a minimal response (≥25% M-protein decrease) or better. Responses were assessed using the European Bone Marrow Transplant criteria.

Results

There were no significant differences in the rates of partial response or better between patients with stable or progressive disease. However, 38% of the patients with stable disease at the time of transplantation remained in a stable condition or achieved a minimal response after transplantation versus 7% in the group with progressive disease (P=0.0017) and the rate of early progression after transplantation was significantly higher among the group with progressive disease at the time of transplantation (22% versus 2%; P=0.0043). After a median follow-up of 6.6 years, the median survival after first transplant of the whole series was 2.3 years. Progression-free and overall survival from the first transplant were shorter in patients with progressive disease (0.6 versus 2.3 years, P=0.00004 and 1.1 versus 6 years, P=0.00002, respectively).

Conclusions

Our results show that patients with progressive refractory myeloma do not benefit from autologous transplantation, while patients with stable disease have an outcome comparable to those with chemosensitive disease.

Role of novel DSP_p.Q986X genetic variation in arrhythmogenic right ventricular cardiomyopathy

Introduction

Arrhythmogenic right ventricular cardiomyopathy is an inherited disease characterized by a progressive myocardium fibrofatty replacement. This abnormality disrupts electrical transmission causing ventricular arrhythmias and sudden cardiac death. This genetic disease is transmitted mainly with an autosomal dominant pattern. Our aim was to identify the genetic defect responsible for the pathology in a Spanish family, and to perform its phenotype connotations.

Material and methods

A total of 15 individuals in a three-generation Spanish family were screened after the sudden cardiac death of one family member. All they underwent a complete physical examination, 12-lead electrocardiogram, 2-dimensional echocardiography, magnetic resonance imaging, exercise stress test, 24-h Holter and genetic testing.

Results

Autopsy revealed the presence of biventricular arrhythmogenic dysplasia in deceased member. Six family members showed clinical symptoms but only three of them fulfilled definite diagnostic criteria of the disease. Genetic analysis showed a novel nonsense genetic variation in nine family members. All family members with clinical symptoms carried the genetic variation.

Conclusions

Genetic testing in families affected by arrhythmogenic right ventricular cardiomyopathy helps to identify the genetic cause responsible for the disease. The incomplete penetrance and variable phenotypic expression highlights the need of comprehensive genetic analysis and further phenotype implications of genetics to clarify the pathophysiology of the disease.
