With 4-7 cases of Rhinonasal polypsis in Eto-rhino-laryngologic center, from January 1998 to January 2001, in the age of 16-60 years. The ethmoidectomy via endoscopic technique and receive high efficacy result: 97% decrease nasal obstruction post op, 0% of orbital and intracranial complications, and specially 27% has appeared the minimal recurrent polyps on the anterior ethmoid which did not remove, just only use the steroid spray. Preparing the pre-op period with antibiotic, anti-inflammatory 93.7% and planned regularly patient's examination each month per year. Others factors such as asthma 13%, allergic zhinitis 24%, tobacco 15% were well studied to improve the result of the endoscopic ethmoidectomy and to limit the recurrent polyps

Background: FISH can detect number and structural chromosome aberrations in DNA. FISH is new technique in Vietnam, we combine FISH with chromosome analysis to prenatal diagnosis Down syndrome and turner syndrome that are high rate in birth defect.Objectives: To detect Down syndrome and turner syndrome by using FISH technique with chromosome analysis from amniotic cell.Subjects and method: 14amniotic cells samples 15th - 20th week with high risk of birth defects. Advance using FISH and chromosome analysis from amniotic cell. Results: We obtained results as follow: - 14/14 samples: correspondence between FISH and chromosome analysis. \ufffd?Detected 2 Down syndrome (female. Trisomi 21) and 4 Turner syndrome (45, X). Conclusion: Detected Down syndrome and Turner syndrome by using FISH technique with chromosome analysis from amniotic cell.

Background/Introduction:The proportion of TS \u2013 Q96 ranges from 1/1500 \u2013 1.300 female newborns and about 3% of fetuses. In most of the world, TS can be diagnosed and treated at the early stages of pregnancies. In Vietnam, TS patients are frequently detected at the later stages with serious syndromes. TS diagnosis mainly relies on chromosomal analysis of amnion cells. Thus, prenatal diagnosis of TS is the rationale of this study.\r\n', u'Objectives: Utilize chromosomal analysis and FISH methods to diagnose Turner syndrome from amnion cells. \r\n', u'Subject and method: 30 pregnancies (from week 14-22) with high risks of TS, which were detected by ultrasound scan and triple test, 15 mil amnio fluid is withdrawn for the FISH technique from interphase amniocytes and amnio cultures, chromosomal analysis from metaphase cultured cells. \r\n', u'Results/Outcomes: Chromosomal analysis and FISH analysis give the same results: - 12/30 fetus with TS, 5/30 fetus with normal female results, \u2013 4/30 fetus with normal male normal results, \u2013 4/30 fetus with Down syndrome, \u2013 5/30 fetus with Edward syndrome. 11/12 TS fetus have large cystic hygromas, 9/11 cystic hygromas are separated. 12/12 TS fetus have triple test (+) with the threshold: APF \u2264 0.7 MoM, HCG \u2265 2 MoM, uE3 \u2264 0.7 MoM.\r\n', u'Conclusion:Chromosonal analysis and FISH are standards for diagnosing TS fetus. FISH can provide a quick result (48-72h). \r\n', u'

Background: Cystic hygromas is a common abnormal event in obstetrics ultrasound, which is induced by a chromosome disorder; it is also one of the major causes inducing fetus\u2019s congenital malformation. Objective: Determining chromosomal aberration in nuchal cystic hygromas by FISH technique and outcomes the value of factors in prognosis fetuses with cystic hygroma. Subject and methods: 53 fetuses with cystic hygroma, which are detected by ultrasound scan, are analyzed by FISH technique. Compare results of FISH, band G chromosomal analysis, ultrasonographic abnormalities, followed the fetuses. Results: Chromosomal and FISH analysis give the same detection: abnormal chromosomes: 75.46%, the highest rate is Turner syndrome: 50.94%, normal chromosome: 24.53%. Abnormal chromosomal fetuses: multi-malformation, grim prognosis. Cystic hygroma with other malformation in scan: high rate chromosomal aberrations and septated hygroma, Turner syndrome fetuses have large cystic hygroma, 4/6 fetuses with normal chromosome and without other abnormal result scan have resolutions of hygroma in the second trimester, normal birth. Conclusions: Abnormal chromosomes: 75.46%. Prognosis is grim: abnormal chromosomes, other malformations in scan, large cystic, septated hygroma. Prognosis is better: normal chromosomes, without other ultrasonographic abnormalities, small cystic, nonseptated hygroma, resolution of cystic hygroma.

Background: According to WHO, there are 5 million deaths from kinds of injury a year in the world, of which 875000 deaths occur in children under 18 years old. Injury leads to 40000 deaths which account for 10.7% deaths due to all other causes a year in VietNam. Objective: To show conclusions of the situation of child injury, recommendations for prevention of child injury and methods in order to enhance emergency activity in Vietnam. Subjects and method: The authors collected information about all patients who had emergencies due to injury at Viet Duc hospital, from March 26th 2006 to Octorber 26th 2006. However, supervised cases were the patients under 18 years old who were examined and treated at the Department of Emergency. Results: During the period of study, 2536 patients under 18 years old were examined for injury, of which death and coming back home for death were 83 cases (3.27%). 974 children had emergency resulted from injury: male was more than female: 697 verus 227. The leading causes of child injury were fall and traffic accident, respetively 34% and 60%. The most common traumas were traumatic brain injury (45%), limbs injury (41%). Although most of cases had first aid at the hospitals in district or province level, the rate of non-first aid cases was high (34%). Conclusion: Child injury is a leading cause of child death in hospitals. Methods for prevention of child injury should focus on educating and propagandizing to minimize injuries caused by traffic accident and fall.

ABSTRACT This study aims to compare the effect of fTCP-contained toothpaste in combination with 950 ppm fluoride on primary dentin caries surface to ordinary 1100 ppm fluoride toothpaste by using estimation statistics. Dental caries with deep lesion and dentin exposure from nine primary teeth were cut into two equal parts and randomly divided into two groups in a before-after study. Each group was brushed with one type of toothpaste two times per day for 28 days and rested in artificial saliva. SEM images of cavity bottom surfaces and energy-dispersive X-ray spectrometry (EDX) were used to determine the percentage of calcium (Ca), phosphorus (P), fluoride (F) and oxygen (O) at six continuous measured areas from the surface of the cavity bottom into 45 µm depth before and after brushing. About 95% confidence interval of the mean difference was calculated by performing bootstrap resampling with 5000 resamples followed by comparison analysis. The percentage of Ca, P, F, O was shifted after treatment. There was no difference between the two groups. The SEM images reflected a similar illustration of EDX data. The combination of fTCP and 950 ppm fluoride in toothpaste showed equivalent effectiveness to the 1100 ppm fluoride toothpaste in primary dentin caries.
