ABSTRACT
Objective To investigate the incidence of dyssomnia,posttraumatic stress disorder (PTSD) and their relationship in earthquake survivors in Jiangyou and Beichuan area,and supply evidence for prediction and treatment of PTSD.Methods Dyssomnia was accessed by Pittsburgh Sleep Quality Index (PSQI),posttraumatic symptoms were measured using the PTSD Checklist-Civilian Version (PCL-C).Results The prevalence of dyssomnia was 33.8％,the PTSD was 7.5％.In good sleep group,the number of people who didn't suffer from PTSD was 358 (96.5％),the number of people who suffered from PTSD was 13 (3.5％); In dyssomnia group,the number of people who didn't suffer from PTSD was 160(84.7％),the number of people who suffer from PTSD was 29(15.3％).In PTSD negative group,the number of people who had good sleep was 358 (69.1％); the number of people who had dyssomnia was 160 (30.9％).In PTSD positive group,the number of people who had good sleep was 13(31.0％),the number of people who had dyssomnia was 29(69.0％).The correlation analysis showed that total scores of PCL-C were positively related with total score of PSQI.The logistic regression showed that the very hard-hit area,serious posttraumatic symptoms,were the dangerous factors of dyssomnia.Conclusions The dyssomnia and PTSD are still common among victims two years after 5.12 earthquake.PTSD can cause sleeping problem,meanwhile sleep problem could increase the risk of PTSD.
ABSTRACT
Objective To discuss the community-based psychological support model for people living with HIV/AIDS. Methods A community-based psychological support team was set up. The team composed of psychology experts,community volunteers,community physicians,community nurses and family members of patients. It provided psychological care and emotional support to people living with HIV/AIDS through activities such as psychological counseling,health education,anti-discrimination advocacy and peer exchanges. Results This model significantly reduced the anxiety and depression,and increased life satisfaction of people living with HIV/AIDS(P<0.01). Conclusions The community-based psychological support model has more advantages than the traditional psychological support. It gives full play to the community on AIDS prevention and control functions,as well as has great significance to mobilize social forces to control the spread of AIDS.
ABSTRACT
Objective To study the normal microanatomy and HRCT findings in nasal bone part which is easy to be confused with the bone fracture, thus increasing the diagnostic accuracy of nasal bone fracture. Methods CT findings were compared between two groups 60 volunteers as normal group and 30 cases with nasal bone fracture as trauma group, which were all performed with HRCT in transverse and coronal scans to find the differences. Results Three experienced radiologists observed the films of the normal group in blind. 54 cases were diagnosed normal, 3 were suspected to have fracture, and 3 misdiagnosed as fracture. (1) There were some normal nasal structures which were susceptible to be confused with fracture, such as bone suture, internasal aperture, intersuture bone, and normal variations. (2) On transverse and coronal scan, nasal-maxillary suture demonstrated various characteristics, including 57 cases and 3 cases of inflated type, 39 and 5 of occluded type, 31 and 6 of intersuture bone, 16 and 34 of thin bony shapes, respectively. (3) Sometimes the extremity of outside was too depressed or flat which was related with the development, and it included 12 cases in left and 13 in right of inner alcula type, 4 in left and 4 in right of outer raised shape on coronal images, which were easily confused with fragment of fracture. But the conformation and structure were intact on transversal images, thus fracture could be excluded. Conclusion The understanding of morphological structure and characterized imaging findings can reduce the incidence of clinical misdiagnosis. Nasal bone fracture is not rare in facial trauma, and the following points should be paid attention to: 1.Normal nasal structures and variations of the nasal bone. 2.The scanning methods with HRCT. 3.Combination of the transversal and coronal scan can reinforce and testify with each other.
