The free iliac rest flap based on the Deep Circumflex lilac Artery (DCIA) and Vein (DCIV) has proven to be a useful technique with a high rate of success. It provides a large segment of strong bicortical bone that was sufficient to reconstruct up to two thirds of mandible and supplied by blood vessels with large and long enough to allow for consistently successful anastomosis. It also uses a donor site located for enough from the neck to allow two teams perform operation in the same time with minimum of complication.

5 patients with large inferior maxillary ameloblastoma treated at the Hospital 108 were with good outcomes. The technique involves 3 steps: Step 1: Preoperative evaluation and preparation. Step 2: The operation was conducted by 2 shifts of surgeons. The first shift takes off the autologous iliac crest flap. The second shift removes the section of maxillary bone that contained tumor and prepares the blood supply vessel. Then the flap was inserted into the inferior maxillary area, controlled and stabilized for 2 ends. Step 3: Post-operative following, in which it is important to follow the circulation of vascular anastomosis, the situation of skin with bone flap and ultrasonographic imaging.

A cross with comparison study was conducted at the end of 1999 at 2 kindergartens of Trang An and Trung Tu, Dong Da district, Ha Noi. The study group consisted of 5 year old children who lived near the main roads, and the control group consisted of 5 year old children who lived far from roads > 100m. The total was 87 children (38 females, 49 males). 47 children in Trung Tu kindergarten and 47 children in Trang An kindergarten. Results: the level of lead in house dust of control group was 181.08 g/g, compared with the level was 164.57 g/g in study group. The difference was not statistical. In the study group, lead content in the hair of children was 8.47 g/g , while in the control group it was 6.14 g/g, the difference was significant and statistical (p<0.05).

Study on Van Chang hamlet, Nam Giang commune, Nam Truc district, Nam Dinh province was conducted at the end of 2003. The results showed that the employees of Van Chang hamlet and the leader, board committees of Nam Giang commune had good knowledge about the impact of mechanical processing activities on the living environment also the polluted level in hamlet. All leaders and people hoped their environment will be improved. They wished to get the support from the local authorities and professional bodies for the overall solutions and they were also ready to participate in the improving environment.

Our study was carried out on children who lived in the main streets and children who lived at Vanphuc commune, Thanhtri district, Hanoi that is far from the main roads and streets. Results have shown that air lead, precipitated dust and floor dust were statistical significant higher than control and exceeded many times to allowed standards. The lead level in drinking water and food did not play a significant role in differentiation between lead level in the bodies of children. The hair lead level in children who lived in the main streets was significant higher than this in control.

200 patients over 18 years old were diagnosed with peptic ulcer. Two specimens were taken on each patient: from the corpus and 1/3 andral, which were put into each urease test hole. The results were diagnosed with H. pylori infection with urease test by reading biopsyspecimen after 1 hour and 24 hours. With 83.5% patient having used drugs before endoscopy, the percentage of H. pylori (+) from the corpus and the antral specimen is significantly different (65% vs 68.5%) but using specimens from both sites increases significantly the H. pylori positivity from 65% to 78%

Background: Hypertension is an important risk factor that increases the cardiovascular disease-related morbidity and mortality, especially in elderly people. Objectives: The study aims to identify the hypertension rate among elderly residents of Can Tho city and some demographic, economic and social factors that were associated with hypertension in view of hypertension is changing with social and economic development. Subjects and method: The cross-sectional study involved 594 elderly people who were living in Can Tho city. Blood pressure was measured by the Korrotkoff method. The demographic, economic and social information was collected using questionnaire-based direct interviews. Results: The hypertension rate was quite high in the elderly group (51.9%). According to the WHO\u2019s ISH criteria, stage III occupied nearly 10%, stage II was approximately 15% and nearly one third of them in stage I. Age and living location were found to have significant impact to blood pressure status. Compared to the age group of 60 to 69, the elderly people in the age group of 70 to 79 were more likely to have hypertension by one and half times. And the risk was more than twice as high in the age group of 80 and above. These relationships were significant to p<0.05. The elderly people who were living in rural areas had twice the chance of having hypertension than those living in urban areas (p<0.001). Conclusion: The hypertension rate was quite high in elderly people in Can Tho city, Viet Nam. Age and living place were factors related to hypertension status in the elderly.

Background: Limitation of daily activities is the obstacle that prevents the elderly from achieving their desires. Objective: Aim to discover the prevalence and risk factors of the limitation in daily activities in the elderly. Subject and methods: This cross - sectional study was conducted in 4 provinces: Thai Nguyen, Ha Tay, Hue and Can Tho during June to December 2006 among 2.644 people at the age of 60 and above. Results: The overall prevalence of limitation of the elderly is 5.6%, and 4.3% is totally dependent and 1.3% is partly dependent. This proportion increases with age. It happens more in urban areas as opposed to rural and mountainous areas. Those living with their spouse have lower proportion of limitations. Can Tho and Ha Tay has the higher proportion of limitation than Hue and Thai Nguyen. Factors related to these limitations are aging (OR = 1.08; 1.06-1.10), not working at the current time (OR = 0.11; 0.05-0.28), ethnicity (OR = 2.25; 1.45-3.49), lack of physical exercise (OR = 2.24, 1.75-3.85), brain damage (OR = 15.18; 9.47-24.35), dementia (OR = 2.39; 1.62-3.54) and loss of vision (OR =1.32; 1.05-1.65). Conclusion: The limitation in daily activities tremendously affects the quality of life for the elderly. Age, working status, race, physical activity, accident of cerebral vessels, dementia and vision loss are statistic significant related factors for the limitation in daily activities of the elderly

Timely analysis of imaging data is critical for diagnosis and decision-making for proper treatment strategy in the cases of ischemic stroke. Various efforts have been made to develop computer-assisted systems to improve the accuracy of stroke diagnosis and acute stroke triage. The widespread emergence of artificial intelligence technology has been integrated into the field of medicine. Artificial intelligence can play an important role in providing care to patients with stroke. In the past few decades, numerous studies have explored the use of machine learning and deep learning algorithms for application in the management of stroke. In this review, we will start with a brief introduction to machine learning and deep learning and provide clinical applications of machine learning and deep learning in various aspects of stroke management, including rapid diagnosis and improved triage, identifying large vessel occlusion, predicting time from stroke onset, automated ASPECTS (Alberta Stroke Program Early CT Score) measurement, lesion segmentation, and predicting treatment outcome. This work is focused on providing the current application of artificial intelligence techniques in the imaging of ischemic stroke, including MRI and CT.
