Entering exile: trauma, mental health, and coping among Tibetan refugees arriving in Dharamsala, India

Each year thousands of Tibetans escape Chinese-controlled Tibet. The authors present findings on the experiences, coping strategies, and psychological distress (depression, anxiety, somatization, and posttraumatic stress disorder) of 769 Tibetan refugees arriving in Dharamsala, India (2003-2004). Distress increased significantly with greater trauma exposure. However, despite a high prevalence of potentially traumatizing events, levels of psychological distress were extremely low. Coping activity (primarily religious) and subjective appraisals of trauma severity appeared to mediate the psychological effects of trauma exposure. The potential impact of other variables, including culturally determined attitudes about trauma and timing of assessment, are discussed.     

Traumatic experiences and psychological distress in an urban refugee population seeking treatment services

While a growing literature has addressed the psychological consequences of torture and refugee trauma, most studies have focused on homogeneous samples drawn from a single region. Thus, relatively little research has attempted to identify demographic or experiential factors that might help explain different levels of distress in these individuals. We measured depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms in a convenience sample of refugees and survivors of torture seeking treatment in a torture treatment program (N = 325). We found 81.1% of patients had clinically significant anxiety, 84.5% had clinically significant depressive symptoms, and 45.7% had significant PTSD symptoms. Regression analyses revealed that anxiety and depressive symptom were significant higher among women (beta = .08, p = 0.02 and beta = .22, p = 0.0001 for anxiety and depression respectively) and those who reported death threats as part of their traumatic experiences (beta = .10, p = 0.033 and beta = .12, p = 0.036 respectively). Symptoms of PTSD were also predicted by death threats (beta = .22, p = 0.03), but were also influenced by the experience of rape (beta = .33, p < 0.001), family torture experiences (beta = .23, p = 0.022), religion (beta = .21, p = 0.03), and age (beta = -.18, p = 0.004). The clinical implications of these results are discussed.     

Pros and cons of colonoscopy in management of acute lower gastrointestinal bleeding

Acute lower gastrointestinal bleeding (LGIB) is a frequent gastrointestinal cause of hospitalization, particularly in the elderly, and its incidence appears to be on the rise. Endoscopic and radiographic measures are available for the evaluation and treatment of LGIB including flexible sigmoidoscopy, colonoscopy, angiography, radionuclide scintigraphy and multi-detector row computed tomography. Although no modality has emerged as the gold standard in the management of LGIB, colonoscopy is the current preferred initial test for the majority of the patients presenting with hematochezia felt to be from a colon source. Colonoscopy has the ability to diagnose all sources of bleeding from the colon and, unlike the radiologic modalities, does not require active bleeding at the time of the examination. In addition, therapeutic interventions such as cautery and endoclips can be applied to achieve hemostasis and prevent recurrent bleeding. Studies suggest that colonoscopy, particularly when performed early in the hospitalization, can decrease hospital length of stay, rebleeding and the need for surgery. However, results from available small trials are conflicting and larger, multicenter studies are needed. Compared to other management options, colonoscopy is a safe procedure with complications reported in less than 2% of patients, including those undergoing urgent examinations. The requirement of bowel preparation (typically 4 or more liters of polyethylene glycol), the logistical complexity of coordinating after-hours colonoscopy, and the low prevalence of stigmata of hemorrhage complicate the use of colonoscopy for LGIB, particularly in urgent situations. This review discusses the above advantages and disadvantages of colonoscopy in the management of acute lower gastrointestinal bleeding in further detail.     

Effectiveness of antenatal group HIV voluntary counseling and testing services in rural India.

This study assessed HIV attitudes among pregnant women attending antenatal clinics in the Namakkal district of Tamilnadu, India, as well as HIV knowledge before and after group counseling sessions. Two hundred thirteen women (97%) attending five antenatal clinics in July 2004 accepted HIV counseling and testing and completed precounseling and postcounseling questionnaires. Although the majority of women had heard of HIV, precounseling knowledge was low (mean precounseling score; 6.9/18, SD: 4.53), with scores correlating with the women's educational level and the number of sources from which they had received information about HIV. Posttest scores increased by 21%, however, understanding of modalities to prevent HIV infection remained poor. Group counseling sessions achieve small gains in HIV knowledge, but there is a continued need for ongoing and multifaceted HIV education in rural India.     

Screening for PTSD among Somali adolescent refugees: psychometric properties of the UCLA PTSD Index

This study presents the psychometric properties for the UCLA Posttraumatic Stress Disorder Index among a sample of Somali adolescents. Data were derived from a sample of English-speaking Somali adolescent refugees between the ages of 12 and 19 years (n=76). The UCLA PTSD Index showed good reliability (Cronbach's alpha=.85). Convergent validity was assessed through bivariate correlations with the Depression Self Rating Scale (r=.72, p<.001) and the War Trauma Screening Scale (r=59, p<.001). Results suggest that the UCLA PTSD Index may be a reliable and valid screening tool for PTSD symptoms for use with Somali adolescent refugees.
