[Imaging of brain tumors in adults by tomodensitometry and magnetic resonance imaging].

Adult brain tumors comprise a remarkably diverse group of histologic varieties; the potential of CT and MRI for diagnosing presence of tumors of the brain and evaluating their extension is well recognized. A precise radiologic diagnosis can be often made as for as extra-axial tumors are concerned. On the contrary this is often more difficult for intraparenchymal tumors.

The Khmer Adolescent Project: III. A study of trauma from Thailand's Site II refugee camp.

OBJECTIVE: To determine the prevalence rates of posttraumatic stress disorder (PTSD) and depression in a sample of 99 Cambodian youths, aged 18 to 25 years, living in the Site II refugee camps along the Thai-Cambodian border; to compare these rates to data collected in a similarly aged sample of Cambodian refugees living in the United States; and to illustrate the findings with case vignettes and a brief description of the refugee camp at Site II. METHOD: The senior author describes the main features of life in the Site II camp while being employed in one of its medical clinics. A Khmer translated version of the depression section of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic Version and the PTSD section of Diagnostic Interview Schedule for Children and Adolescents were used in interview format by trained bilingual research assistants. Khmer versions of the Beck Depression Inventory and the Impact of Events Scale were also administered. RESULTS: The enduring nature of PTSD was evident in this sample of Khmer youths who had survived the Pol Pot regime as children. Similar rates of Pol Pot-related PTSD were found when compared to rates from the US sample. Subclinical forms of PTSD were found in those who reported their worst trauma during life in the camp, while the full PTSD syndrome was associated with those who reported trauma occurring during the earlier Pol Pot regime. Extremely high rates of depressive disorder were found which were interpreted as related to the repatriation back to Cambodia as this study was undertaken. CONCLUSION: PTSD in this sample appears to be specifically related to earlier war trauma, while depressive symptoms appear more related to recent stressors. As with other findings from the Khmer adolescent project, this study reaffirms the strong connection between the diagnosis of current PTSD and earlier war trauma in an additional sample of youths at Site II, Thailand. Depressive symptoms, on the other hand, appear to be related to the vicissitudes of recent stressful events in this refugee population.

[MRI of degenerative extrapyramidal syndromes. Parkinson disease, progressive supranuclear palsy and multiple system atrophy].

MR imaging of the brain, particularly with high field MR imagers, may demonstrate signal abnormalities consistent with deposits of iron or other paramagnetic substances in extrapyramidal disorders. The diagnosis of Parkinson's disease and progressive supranuclear palsy can be made on clinical grounds in most of the cases and MR signs are of little help in the diagnosis of these diseases. In patients with parkinsonian disorders poorly responding to therapy, MR imaging may be useful in demonstrating signal abnormalities in the putamen that may help to establish the diagnosis of striatonigral degeneration (component of multiple system atrophy) with a poorer prognosis than Parkinson's disease. Finally, MR imaging may be useful in the exclusion of other disease processes.

Family therapy of extrafamilial sexual abuse.

A significant portion of children referred for psychiatric treatment have been sexually abused. One of the most difficult symptom manifestations to treat in young children is the management of anger. In this case, a 4-year-old boy was sexually abused by persons outside the family. He showed symptoms of regressive behavior including encopresis, enuresis, difficulty sleeping, fearfulness, recurrent nightmares, and had hyperalertness and frequent outbursts of anger. Treatment initially involved group therapy, with a concurrent parents' group. After experiencing little improvement in group therapy, the youngster was put in individual play therapy and family therapy. Family therapy proved essential in creating a safe environment for the patient where he could learn to regulate his affect and process his traumatic experience successfully.
