OBJECTIVE: The authors describe the psychiatric assessments and trauma testimonies of 20 Bosnian refugees of "ethnic cleansing" who have recently resettled in the United States. METHOD: Refugees referred from agencies managing refugee resettlement underwent systematic, trauma-focused, clinical interviews that included standardized assessment scales. RESULTS: The traumatic experiences of ethnic cleansing in these Bosnian refugees were genocidal in nature. The number of types of traumatic experiences correlated positively with age. Posttraumatic stress disorder (PTSD) was diagnosed in 65% of the refugees, and depressive disorders in 35%. PTSD severity scores were correlated with the number of types of traumatic events experienced. CONCLUSIONS: Ethnic cleansing has caused high rates of PTSD and depression, as well as other forms of psychological morbidity, in this group of resettled Bosnian refugees. The longitudinal sequelae of ethnic cleansing as a form of massive psychic trauma remain to be studied. 相似文献

OBJECTIVE: The authors sought to describe the use of the testimony method of psychotherapy in a group of traumatized adult refugees from genocide in Bosnia-Herzegovina. METHOD: The subjects were 20 Bosnian refugees in Chicago who gave written informed consent to participate in a case series study of testimony psychotherapy. All subjects received testimony psychotherapy, averaging six sessions, approximately 90 minutes, weekly or biweekly. Subjects received standardized instruments for posttraumatic stress disorder (PTSD), depression, traumatic events, global functioning, and prior psychiatric history. The instruments were administered before treatment, at the conclusion of the treatment, and at the 2- and 6-month follow-ups. RESULTS: The posttreatment assessments demonstrated significant decreases in the rate of PTSD diagnosis, PTSD symptom severity, and the severity of reexperiencing, avoidance, and hyperarousal symptom clusters. Depressive symptoms demonstrated a significant decrease, and there was a significant increase in scores on the Global Assessment of Functioning Scale. Two-month and 6-month follow-up assessments demonstrated further significant decreases in all symptoms and an increase in scores on the Global Assessment of Functioning Scale. CONCLUSIONS: This pilot study provides preliminary evidence that testimony psychotherapy may lead to improvements in PTSD and depressive symptoms, as well as to improvement of functioning, in survivors of state-sponsored violence. 相似文献

Endodontics is no stranger to controversies. For most of the first 50 years of the 20th century, a cloud hung over endodontic therapy of any kind, as problems with the focal infection theory were attributed to pulpless teeth causing a wide variety of maladies. Even recently, endodontic treatment has been attacked as being responsible for many chronic and acute illnesses, despite a multitude of information to the contrary. The controversies we discuss here, however, have nothing to do with the decision to treat, where we have no doubt as to the efficacy for therapy, but rather how such treatment should be rendered. Controversies have raged in the past, such as silver points vs gutta-percha as the canal filling material of choice, and to culture or not to culture, to name just two. The subjects discussed in this series of articles are those that have come up much more recently or older topics that have returned as areas for disagreement: (1) lateral canals: filling and significance; (2) single-appointment vs multiple-appointment treatment; (3) filling from the open position; and (4) calculation of working length. This article addresses single-appointment vs multiple-appointment treatment. 相似文献

Root canal models were implanted in rats in order to investigate histologically the movement of granulation tissue invading apical canals and dead spaces and changes in cell proliferative activity as indicated by 3H-thymidine. The models were prepared to have 1, 2, and 3 mm apical canals, with and without dead spaces, to simulate preparations short of the apex and obturation to several levels. After 12 wks implantation of the models without dead spaces, granulation tissue invading 1 mm apical canals did not degenerate and cell proliferative activity remained high. However, tissue invading the 2 and 3 mm apical canals tended to be necrotic and cell proliferative activity was decreased. In the models with dead spaces, the tissue in the 1 and 2 mm apical canals developed and invaded the dead spaces, and still possessed proliferative activity 12 wks after implantation. In contrast, the tissue in the 3 mm apical canals did not invade the dead spaces, even after 12 wks, and no proliferative activity was observed. 相似文献

A program for quality assurance of reference standards has been initiated among nine solar-UV monitoring laboratories. By means of a traveling lamp package that comprises several 1000-W ANSI code DXW-type quartz-halogen lamps, a 0.1-ohm shunt, and a 6-1/2 digit voltmeter, the irradiance scales used by the nine laboratories were compared with one another; a relative uncertainty of 1.2% was found. The comparison of 15 reference standards yielded differences of as much as 9%; the average difference was less than 3%. 相似文献
