SUMMARYCRIMINALS’ KNOWLEDGE IN HIV/AIDS

PREVENTION AT DIEN BIEN PRISON IN 2009Nguyen Xuan Bai, Thai Binh Medical College

Hoang Xuan Chien, Dien Bien Department of HealthCriminals have high risks o f acquiring HIV,

accounting for more than 1/10 among HIV cases in Vietnam in 1998 [2], It is necessary to evaluate knowledge in HIV/AIDS prevention, from which interventions can be pointed out to reduce HIV/AIDS transmission. Therefore, we performed this cross- sectional research on 400 criminals at Dien Bien prison in 2009. The result showed that:

- 73.7% of criminals acknowledged that HIV transmit through blood; 68.7% of them knew that HIV transmit through sexual intercourse 58.5% of those acknowledged that HIV transmit from mother to child.

- 48% of criminals supposed that there has not been cure for AIDS; 42,3% o f criminals had no idea about treatment for AIDS.

- 67.5% of criminals had knowledge in HIV exposure, 62.7% of criminals knew how to manage

SUMMARYDiagnosing the cholesteatoma without

tympanic membrane perforation by endoscopy and CT Scan compare with the results of surgery

n g u y £ n t An PHONG80 mdn TMH DHYHN

Congenital cholesteatomas are defined by Derlacki as an embryonic rest of epithelial tissue in the ear without tympanic membrane perforetion and without history of ear infection. Congenital cholesteatomas may be found in the middle ear or in the petrous apex .

Objectives: 34 patients with cholesteatomas without tympanic membrance perforation frome 5 to 44 ages

Methods: Diagnosing cholesteatoma without tympanic membrane perforation by endoscopy, Audiometre comper with CT scane

Results: There are 3 groups defferall symptoms for 3 positions o f the cholesteatomas.

Conclusion: Cholesteatomas located in the tympanic cavity always has the conductive hearing loss. Cholesteatomas presented in the ear canal coming from congenital atresia
