We describe a case of factitious disorder with physical and psychological symptoms comorbid with bipolar I disorder in a 37-year-old woman. Since the onset of bipolar disorder, which occurred at the age of 31, she increasingly complained of physical symptoms, compulsively seeking medical and surgical interventions. She has been hospitalised several times and her Munchausen-type factitious disorder recently appeared to be developing into Munchausen by proxy, involving her 11-year-old daughter. The patient adhered poorly to stabilising and antipsychotic drug treatment and did not improve through the years. We here analyse her mood phases, which were always associated with changes in the quality of factitious symptoms, according to whether the disorder was in its depressive phase (somatic complaints and suicidal ideation prevail), or in its manic or mixed phase (medical intervention-seeking and manipulation of clinicians to obtain surgical interventions). We also briefly discuss some important forensic issues to consider in similar cases, mainly stemming from the psychotic aspects of these two co-occurring disorders. Clinicians should be aware of some patients' ability to produce signs and symptoms of physical and/or psychological illness and consult psychiatrists before giving consent to invasive diagnostic procedures or surgery. 相似文献

Teeth are recently drawing attention for their potential as biological modeling investigation samples due to their ability to be collected and their slow substance metabolism. There is no active metabolism of elements after the completion of dentin. Dentin is surrounded by enamel and cementum, and is not affected by the oral environment. Therefore, the amount of trace elements in dentin may change with age, and this is considered to be a reliable biological load index. The objectives in this study are to demonstrate concentrations of elements in the dentin of healthy Japanese subjects by sex and age, and to reveal the relationship between element levels and age. 121 healthy teeth samples were extracted due to periodontal disease or orthodontic treatment. Each tooth was sliced from the crown to the root apex into 0.5-1mm thickness, then enamel, cementum, and the pulp were removed; the dentins were used as samples. The concentration of 10 trace elements (B, Mn, Co, Cu, Zn, Rb, Sr, Mo, Cd, and Pb) in the dentin was measured using inductively coupled plasma mass spectrometer (ICP-MS). The differences Co and Pb in the dentin between men and women were significant (p<0.01). Significant positive correlation was observed between B, Co, Cu, Zn, Sr and Pb concentrations in the dentin and age (p<0.001). The results of the present study suggest that human dentin is an appropriate substance for relativity with sex and age at further future research. 相似文献

In the process of building a European Private Law, the lawmaking and harmonization dimensions??the modes of harmonization and even more, the scope and reach of the harmonizing effect of the European rules- appear as crucial issues. We show how the harmonization strategy is as important a question as whether we should have European Private Law at all. We present an economic discussion of the different modes of harmonizing Private Law in the abstract, and how they are likely to differently affect outcomes. We also present in informal terms a simple economic model of how to build optimal harmonized rules and standards in a setting of pre-existing separate and diverse national ones, and we systematically explore how the different harmonization regimes (maximum harmonization, minimum harmonization, and pure co-existence of harmonized and national standards) affect the outcomes of the harmonization process. 相似文献

Validation studies of the new DentalPrint software were carried out with experimental bite marks in pigskin. The bite marks were digitally photographed according to the ABFO guidelines for evidence collection. Dental casts used in the experiment were scanned in 3D and 2D, and comparison overlays were generated using DentalPrint and Adobe Photoshop software, respectively. Digitized photographs of the experimental bite marks and the biting edges obtained in the overlays were compared by two different examiners to analyze the impact of training and experience with the two methods. Receiver operating characteristic (ROC) analysis, sensitivity, specificity, and 95% confidence intervals for each cutoff point were calculated. The expert examiner using DentalPrint obtained the best results, with an area under the ROC curve of 0.76 (SE=0.057; CI at 95%=0.652-0.876). Fairly high specificity values were found for DentalPrint, and the best results were obtained for the cutoff value that discriminated between the examiner's response "biter" and the rest of the possible (specificity 97.9%, CI at 95%=93.2%-99.6%). Therefore, the results presented here indicate that DentalPrint is a useful, accurate tool for forensic purposes, although further research on the comparison process is needed to enhance the validity of bite mark analysis. 相似文献

Estimation of population subdivision using genetic markers shows that genetic differentiation in livestock and pet breeds is significantly higher than in human populations. Nevertheless, the influence of population substructure and sample size on match probability has not been extensively analyzed in domestic species. To evaluate the magnitude of the subpopulation effect on estimation of match probabilities in bovine robbery cases, we calculated and compared the match probabilities obtained from cattle breed databases using both real, adjudicated cases from the Buenos Aires Province (Argentina), as well as simulated data. While the Balding and Nichols' correction, when applied to the population database used in the case, produce a more conservative value favorable to the defendant, the match probabilities calculated using the simple product estimator produce a value favorable to the prosecution. We suggest an alternative procedure that can be used. The method consists of choosing the highest value from all match probabilities calculated from the database of each breed. This approach represents an intermediate and more accurate estimation of match probability, although it still produces a slight conservative value favorable to the defense. 相似文献

BACKGROUND: Clozapine is the gold standard in treatment of treatment-resistant psychotic patients. We know little about the effects of compulsory treatment in patients unwilling to accept the necessary treatment. AIMS: To assess the effectiveness, tolerability and safety of compulsory treatment with clozapine (CTC). METHOD: A cohort of 17 consecutive patients given compulsory treatment with clozapine were rated retrospectively by their treating psychiatrists on the basis of their case notes. RESULTS: CGI-S decreased significantly over time until last observation after a mean of more than 15 months. No patient deteriorated as measured by CGI-I. At last observation as many as ten of the 11 patients still on clozapine were classified as much to very much improved. The degree of custodial restriction at last observation showed improvement in 11 patients and no change in six. No serious adverse events were observed. CONCLUSION: A trial of compulsory treatment with clozapine showed this treatment to be feasible, effective, safe and well tolerated. 相似文献
