This study identified the trauma symptoms and life skill needs of 84 domestic violence victims from three domestic violence programs. Women completed two self-report tools: Trauma Symptom Inventory (TSI) and Occupational Self Assessment (OSA). Staff members participated in focus groups regarding their perceptions of the women's needs. Women scored within the clinical range on the Defensive Avoidance (39.8%), Intrusive Experiences (30.1%), and Tension Reduction Behavior (24.1%) clinical scales of the TSI. On the OSA, the groups' priorities differed although all demonstrated a desire to function more independently. Their mental health functioning and prioritization of needs differed based on their level of involvement with the service delivery system. Staff members believe women lack skills in the areas of money management, seeking and obtaining employment, locating permanent housing, independently completing self-care and home management activities, managing stress, and parenting. The findings indicate that both mental health and life skills needs must be addressed.  相似文献

Poppy seeds contain morphine in different amounts. Reported concentrations are up to 294 mg morphine/kg poppy seeds. Since penalties based on Street Traffic Law (parapgraph 24a StVG) in Germany (administrative offence) require definitive proof of morphine in blood samples, and the "Grenzwertkommission" in consultation with the Ministry of Transportation recommended a threshold of free morphine of 10 ng/mL, the question arose whether the consumption of poppy seeds can lead to a blood concentrations equal or higher than 10 ng/mL of free morphine. Therefore, five volunteers ate poppy seed products (50 mg morphine/kg poppy seeds). In urine, all on-site tests were enzyme immunologically positive for opiates and were positive to morphine by GC/MS. All the blood samples were negative to morphine by EIA and to free morphine by GC/MS. However, after hydrolysis, morphine was detected by GC/MS in all cases. Accordingly, in Germany, penalties based on parapgraph 24a StVG are not likely to cause road users any concerns should they have consumed poppy seeds. Driver Licensing Authorities, however, should be advised of this problem to avoid unjustified legal measures.  相似文献

Munchausen syndrome by proxy (MSBP) is a special form of child abuse in which an adult repeatedly produces symptoms of illness in a person under his/her care. In most cases the perpetrators are mothers who repeatedly and in different ways produce or feign symptoms of illness in their children in order to obtain medical treatment for them. MSBP is thus a special form of child abuse that is also of importance in the field of forensic medicine and a particular challenge to the medicolegal expert. We report two cases of poisoning with different substances (clozapine and clonidine) detected by toxicological investigations at our Department of Legal Medicine. The relevance of the problem for the medicolegal expert and the importance of an interdisciplinary co-operation are pointed out.  相似文献
