Remarks on laparoscopic suture of perforated peptic ulcer. Objectives: to evaluate the early result of laparoscopic repair of perforated peptic ulcer. Method: prospective study. The outcome of 26 patients having the lararoscopic repair of perforated peptic ulcer was compared with the outcome of 26 patients treated with suture via laparotomy during the same period – from Sept 1995 to Dec 1998. Results: the average operative time of laparoscopic suture was longer than for open suture (69.6 min Vs. 48.7 min; T test, p<0.05). There was no difference of the time between the laparoscopic and the open groups to resume normal diet (3.8 days). The everage hospitalization days for laparoscopic repair was shorter than for open repair (6 days; T test, p < 0.05). Conclusions: laparoscopic repair of perforated peptic ulcer is feasible, safe and effictive, has the additional and well – known advantages of minimally invasive surgery.

The author collected data by interviewing the leader of centers and chef Laboratory Department of provinces/cities about microbiological test ability of Preventive Medical Centers in 2003. The results showed that Laboratory Departments of Preventive Medical Centers were known thoroughly about base techniques such as culture-isolation, ELISA. The modern methods, techniques in immunology and molecular biology had not developed widespread at centers: PCR was 2.3%, erythrocyte agglutination reaction was 16%. The most provinces could take samples, accurate diagnosis by culture-isolation, biochemical reaction to gastrointestinal bacterium, and some respiratory bacterium. Some disease-induced viruses were: Arbo virus (Dengue, Japanese encephalitis B) and hepatitis B virus, HIV by ELISA technique

Bac Can Centre of Preventive Health has not established the required departments as set forth in decision numbered 2468/1999/QD-BYT yet. There was a shortage of specialized staff, in terms of the number and quality. Moreover, the center' facilities and equipment have not been as proper as its functions. The centers' capacity has concentrated on the scope of epidemic control, health program management, and information technology application. Technical support will be provided with the mode of hand-on-practice for certain subjects

This study was to evaluate the effect of technical support in terms of providing training on integrated management of childhood illness (IMCI) to commune health centers of Quynh Phu district and Hung Ha district of Thai Binh province. The results of a comparison between the baseline survey in 2002 and the follow-up survey in 2004 showed that case management of health workers in 2 districts had improved significantly and were more comprehensive in terms of assessment, classification, treatment and counseling mothers. The proportion of correct assessment of cases on general danger signs increased by 47.5%. The proportion of correct assessment of cases on main symptoms (cough, diarrhea and fever) increased by 63.4%, on the correct classification of cases increased by 72,5% and the correct drug use increased by 46.7%. Th proportion of caregivers/mothers received proper advice on drug use, proper feeding and follow-up increased by 43.5%, 34.9% and 41.1%, respectively

Backgound: Plague disease is one of three most seriously infectious diseases (plague, yellow fever and cholera disease). In Vietnam, this condition has been obviously controlled. The number of new cases and deaths of plague disease have decreased significantly: from 439.6 patients between 1991 and 1995 to 161.2 patients between 1996 and 2000. However, the disease is still circulating in some areas in the world. Objective: To survey plague disease related factors (rats and fleas) at Noi Bai international airport. Subjects and method: A surveillance to inspect plague disease related factors (rats and fleas) was conducted at Noi Bai international airport, Ha Noi, from January/2006 to December/2006. Results and Conclusion: There were two types of rats: R. flavipectus in majority and R. norvegicus. The enrichment index of the two kinds of rats had increased in April and May. R. flavipectus disposed at flat form T1 and R. norvegicus disposed at store area. The only flea species found at the surveillance site was X.cheopis. Bacterial isolation of 236 specimens of liver and spleen, and ELISA tests of 180 blood samples were performed. All of the specimens were negative to Yersinia pestis. The study suggests that the rat populations at Noi Bai airport have not been infected with Yesinia pestis.

Background: Like other countries in the world, Vietnam has seen the appearance of many infectious diseases such as SARS, influenza A/H1N1. Therefore, monitoring and quick response to infectious diseases, increasingly require enhancing the capacity of test systems. \r\n', u'Objectives: To determine the capacity for microbiological diagnosis and etiology of communicable diseases at the provincial centers for preventive medicine.\r\n', u'Subjects and methods: With the application of the cross-sectional approach, the study was conducted on microbiology diagnostic capacity for communicable diseases surveillance and response system in 55 Provincial Preventive Medicine Centers (PPMCs)\r\n', u'Results: Laboratory testing and confirmation (isolation and bio-chemical tests, gram stain) are only available for common nitrobacteria such as Escherichia coli, Vibrio cholera, Shigella, Salmonella, and some of the respiratory bacteria as streptococcus, meningococcus, etc... in most PPMCs. ELISA/MACELISA technique for detecting virus pathogen such as Arbo viruses (Dengue, Japanese B encephalitis) and Hepatitis B, HIV is also a focus of these PPMCs. However, for diseases caused by other viruses like Polio, Rota, measles, influenza, PPMCs have only the ability to collect specimens. \r\n', u'Conclusions: Most of the cases reported in the surveillance reports are based on clinical signs, only. Case confirmation was done by hospital/regional or national laboratory. \r\n', u'\r\n', u'

Background: The reduction of erythrocytes from cord blood is very need for long - term storage of C034 cells for transplantation. Reduced erythrocyte will reduces preservative blood volume, preservatives and freely HST when defrosting, so stem cells are better protected. Objectives: To study selection of the best centrifugal procedure to reduce maximal erythrocytes and lose minimal C034 cells from cord blood. Subjects and methods: 20 blood samples selected from 60 cord blood units was used for this study. The study was carried out through two steps. In the first step, the centrifugal speed was fixed and the centrifugal time was changed.In the second step, the centrifugal time was fixed, the centrifugal speed was changed. From collected results the best appropriate procedure to reduce erythrocytes from cord blood have been selected. Results: The procedure of gradient centrifuge with speed of 500g in 6 minutes isolated> 50% of erythrocytes, kept > 84% of CD34 cells and then centrifuge of 1000 g in 10 minutes reduced about 40% of volume of nuclear cell - suspension. Conclusion: The procedure can use for preparation of stem cell suspension from cord blood to storage in nitrogen liquid. \r\n', u'\r\n', u'
