Study on 80 symptomatic menorrhagia patients less than 18 years old treated at Institute for Protection of Mother and Newborn in the year 2000. Results: the rate of patients with irregular menstruation was highest (38.75%). 70% of patients lived in rural, so the rate of late hospital admission (>15 days) accounted for 73.75%. All patients suffered from anemia with 82.5% patients with moderate and severe anemia. Treatment with 2 tablets Rigevidon a day only one time in the evening until menorrhagia reduces, follows by 1 tablet a day for making artificial menstruation of 28 days, is effective in 96.25% patients. This finding showed that using Rigevidon for treating pubertal menorrhagia is simple, safe, and effective, no significant complication.

A study on 216 patients who had endometrial hyperplasia, these patients had been examined and treated from June 1999 to June 2004 at National hospital of Obstetrics and Gynecology. The patients were divided into 2 groups: Group 1 included 108 patients who were given Orgametril 5mgx 2 tablets/day; group 2 included 108 patients who received only consultation and follow up 6 months after being endometrium curetted. Results: After 6 months of treatment with progestin (Orgametril), there were only 3 patients in group 1 had pathological signs of endometrial hyperplasia (2.8%); 94 patients recovered completely (87%). In group 2, there were 74 patients recovered completely (64.8%) and 19 patients had pathological signs of endometrial hyperplasia (17.6%). After being treated, old patients had endometrium changed into menopause stage: atrophy, thinner and stop working, they also did not have menorrhagia anymore.

Study was carried out on 80 mechanical energy menorrhagia patients under 18 years of age, treated with rigevidon combined with preventive antibiotics and commonly drugs as oxytoxine, ecgometrine at the Newborn & Mother Protection Hospital in 2000. The results showed that: with single dose of 2 tablets per day, taken in unique time in the evening, and then reduction of dose to 1 tablet per day when bleeding stopped, to make a 28 days menstruation cycle, the good efficacy was observed in 96.25% of patients (77 patients respond well to treatment). After, maintain treatment for 3 months following to make an artificial menstruation cycle then stop completely. All of patients had no any seriously complications, including menorrhagia after stopping treatment

Background: Preeclampsia is a major cause of maternal and perinatal mortality and morbidity, affecting 5 - 6% of all pregnancies. Recently, homocysteine (Hcy), a metabolite of amino acid methionine has been postulated producing oxidative stress, endothelial cell dysfunction, and alterations associated with preeclampsia. It is unclear whether high concentration of circulating Hcy causes preeclampsia, or whether this is a secondary phenomenon of metabolic alterations resulting from the disorder. Objectives: (1) Determining blood Hcy concentration in pregnancies in various severities of preeclampsia. (2) Discover the relationships between serum Hcy and other biological markers in preeclampsia. Subjects and method: This descriptive cross-sectional study consisted of 3 groups of pregnancies admitted to Thanh Nhan Hospital: 24 normal pregnant women, 28 pregnancies with non-serious preeclampsia, and 27 pregnancies with serious preeclampsia. Concentrations of blood Hcy of all participants were assayed by a competition fluorescence immunoassay (FPIA). Results: The mean concentration of serum Hcy during normal pregnancy was 5.2+/-1.0micromol/L compared with 7.1+/-1.8micromol/L among pregnancies with non-serious preeclampsia, and 11.7+/-2.9micromol/L among pregnancies with serious preeclampsia. Serum Hcy increased in pregnancies with renal dysfunction, elevated serum uric acid, and injuries of liver cells. Conclusion: Concentration of the serum Hcy in pregnancies with serious preeclampsia is significantly higher than that of pregnancies with non-serious preeclampsia, and the serum Hcy in pregnancies with non-serious preeclampsia is significantly higher than that of normal pregnancies. There are relationships between elevated serum Hcy in preeclampsia with level of kidney failure, injury of liver and increased levels of serum uric acid.

A serological survey was performed using ELISA to estimate the prevalence of tissue and luminal helminthic infections among hospital patients in Hanoi region, Vietnam. An overall seroprevalence of tissue and luminal helminthiases was 64.0% (95% CI 61.2-66.8) among 1,120 patients who visited Hanoi Medical University Hospital, Vietnam in 2018. The highest seroprevalence was observed against Toxocara spp. (59.0%), followed by Strongyloides stercoralis (46.3%), Gnathostoma spp. (25.5%), cysticercus (12.8%), Angiostrongylus cantonensis (10.5%), Fasciola spp. (11.1%), and Clonorchis sinensis (8.7%). Mono-infection by one species (11.1%) was lower than multiple infections (53.0%) (P<0.05). The seroprevalence in males (59.3%) was lower than in females (66.2%) but not statistically significant (P>0.05). Children (<15 years) revealed lower seroprevalence (34.0%) than adults (68.4%), and the age group 51-70 years revealed the highest seroprevalence (76.0%). Among the seropositive patients, eosinophilia (≥8.0%) was noted in 80.2%. The present results suggested active transmission of various tissue and luminal helminths among people in Hanoi, Vietnam.

Background: Japanese Encephalitis (JE) virus is a leading cause of encephalitis in children with high mortality and complication. JE is a dangerous infectious disease via Culex mosquitoes. Objective: To identify the density of some mosquitoes and vectors that transmit JE virus in Ha Nam province. Subject and Method:There were 30.333 mosquitoes including 05 genera and 15 species which were collected at night from April 2006 to March 2007 in the following communes: Tanson (midland area) Hungcong (plain area) and Liemchinh (suburban area). Results: A total of 06 Culex species, the highest rate is Culex tritaeniohychus (41.20%); Culex annulus (15.56%); other Culex species occupied around 0.15% -2.49%. In these communes, the density of Culex tritaeniohychus was higher than Culex annulus. They were found to be active all year round, but the highest density of Culex tritaeniohychus and Culex annulus is 5.86 and 2.15, respectively in April and fall to 4.35% and 1.71% in July. The collected mosquitoes during April, May, June and July includes 133 and 28 Culex tritaeniohychus and Culex annulus pools, respectively; all were to be processed for the isolation of Japanese Encephalitis (JE) virus. There were 12 Culex tritaeniohychus and 2 Culex annulus pools which were collected in Tanson commune yielding positive. Conclusion: The results were confirmed that Culex tritaenioohychus and Culex annulus are the major vectors that transmit JE virus in Ha Nam, 2006 - 2007. All 14 JE virus strains were isolated from collected mosquito pools during April, May and June; whereas JE virus strain was not yet isolated from collected mosquito pool in July. Thus, in order to control JE disease, it is necessary to control JE vectors in April, May and June.

Background: Hemophilia is the most common clotting disorder in the hereditary blood clotting disorders causing harm to health and psychology. The disease can lead to disability and leave the burden on families and society as well as the development of race\r\n', u"Objectives: To study the familial characteristics of haemophiliacs treated at Regional Hematology and Blood Transfusion Center of Hue Central Hospital. Subject and method: This was a prospective study. It included 48 patients diagnosed and treated Haemophilia A and B at Regional Hematology and Blood Transfusion Center of Hue Central Hospital from 7/2005 - 8/2007. Results: In 48 patients, there were 23 patients who had obviously familial history (included 12 families). They were siblings, cousins, maternal grandfathers or mother's brothers. Among 67 haemophiliacs, 23 haemophiliacs had been studied (34.32%), 30 haemophiliacs died of the disease (44.77%). Most of them died at childhood, below age of 15 years (80.64%). Conclusion: Numbers of deaths in the family was not related to the severity of the disease. The age of clinical detection, morphology, number, site, characteristics of haemorrhage as well as the level of articuar injures were not completely the same between the haemophiliacs of the same family. \r\n", u'\r\n', u'
