23 patients (10 males, 13 females) with mitral stenosis aged from 23-50 years of old (mean 37.5 years) were enrolled in the study. Valvular opening area ranged from 0.7cm2 to 1.2cm2. 5 patients have mitral stenosis alone. 18 patients have mitral stenosis with insufficiency grade I, II. 14 patients have sinus rhythm and 98 patients have atrial fibrillation. Pulmonary artery pressure ranged 25mmHg to 45mmHg when measuring directly. There was closed positive correlation between pulmonary artery pressure and right ventricular pressure with r= 0.509 for pre-operation and 0.548 for post-operation. After valve detachment, both pulmonary artery pressure and right ventricular pressure decreased rapidly and dramatically in comparison with prior detachment with p = 0.01.

248 patients participated to a study. The standards of the clinical diagnosis are: epigastric sudden severe pain, pyrexia, vomiting, especially non- remission of pain after vomiting with or without pancreatic pain. The paraclinical: blood amylase must be higher 4 times than normal level; abdominal ultrasound had image of the pancreatic edema and image of ascaris in the pancrea -bile duct (29.44%). If the ascuris is not a cause of the acute pancreatitis, the stress can be a cause of the migration of ascris. Recommendations: use of antihelmintic, use of gentamicine, ampicilline and amoxycilline for patients with accute pancreatitis. In case of the acute pancreatitis due to ascaries, it should combine with antibiotic for anaerobic microbial.

Background: Tophi gout refers to the condition, where consistently high level of uric acid in the body causes the deposition of uric acid or monosodium urate crystals on the joints. Objective: To describe clinical and subclinical features of tophi gout. Subjects and method: A study conducted in 51 patients with tophi gout (according to Bennett-Wood criteria - 1968) in Department of Rheumatology, Bach Mai hospital, from February 2005 to February 2006. This was a cross-sectional prospective study. Results: The average time of tophi appearance lasted 5.3 \xb1 5.7 years. The average number of tophi was 4.5 \xb1 3.9. The most common positions of tophi were tarso - metatarsal - phalangeal joints and elbow joints (43-47%). 100% had gouty arthritis (in which 66.6% > 4 joints), 50-55% involved tarso - metatarsal - phalangeal joints (43.1% had deforming joints). On X-ray, 62.7% cases has injuries, para-articular erosions and overhanging margins (62.5%), joints space narrowing (71.9%), proliferation osseous change (43.8%). Renal stones examined by ultrasound were 41%, renal failure 24.6%. Blood analysis showed hyperuricemia (88.2%), hypertriglyceridemia (54.9%), hyperglycaemia (13.6%). Conclusions: Common features tophi gout were injuries in tarso - metatarsal - phalangeal joints; gouty polyarthritis over 4 joints. X-ray images showed para-articular erosions, joints space narrowing, proliferation osseous changes.

Background:Asthma is a chronic infectious disease of respiratory which affect to health, study, labor and social activities. It can be occur at all age, the rate of incidence of this disease and mortality is increasing. Objectives:This study aims to learn about the clinical features and treatment results in children with asthma admitted into pediatric department, Thai nguyen Central Hospital. Subjects and method: A retrospective study was carried out on 65 asthma children who admitted to Asthma children of Department of Pediatrics, Thai Nguyen Central hospital in order to find the frequency, risks factor, clinical and management ofasthma from 1st January 2004 to 31st December 2006. Results:The asthma rate was 0.81 % among total inpatients and 2.87% among total patients admitted into the Respiratory Department. 30.8% of patients aged from 3 to 6 years old without sex predominance. The children were admitted more often in April, May, September, October and November. Personal and family history of asthma was seen in 70.77% and 35.38%, respectively. The common signs were: cough in 93.9%, coryza in 89.2%, intercostal retraction in 87.7%, wheezing in 80.0%, dyspnea in 66.2%. 4. Management: Bronchodilatator in 100%, antibiotics in 95.4%, corticoid in 76.9%. Improvement was seen in 98.5% and death in 54%. Conclusion: Drugs to lessen cough, phlegm and infusion were not encourage in asthma treatment.

Background: Bacterial vaginosis is a very common vaginal infection. It occurs when bacteria that normally exist in small numbers in the vagina multiply rapidly. With the purpose of early diagnosis and timely treatment infection of vaginalis tract. Objectives: The study was conducted with 2 purposes: Firstly, identification of bacterial and fungical causa is of the vaginalis. Secondly, comparison of the cause among 2 groups of women with clinical symptoms and group came for health examination. Subjects and method:A cross-sectional study was carried out in sampled groups: 325 women with ginecological symptom and 385 women came for health examination at the clinic of the Institute of mother and Newborn protection. Both 2 groups were clinical examined and microbiological testing. Results: The results were showed: The prevalence of vaginalis of the group with ginecological symptoms was found 76.92% and in the other group was 56.1%. The was not any disparity in clinical and testing results. The microbiological causes were found: 22.15% candida in group with clinical symptom and 18.96% in the other group. Streptococcal group D was taken second place 20.61% in group with clinical symptom and 13.25%in group with health examination and folioing are S. aureus, E.coli, C.trachomatis, G.vaginalis. Conclusion: There\u2019s no significant difference in the prevalence of infection of vaginalis tract between some age groups in this study.

Background: Respiratory distress is one among the leading reasons cause mortality for infants especially for preterm babies or light weight babies. Surfactant therapy in premature infants can decrease mortality, duration of respiratory treatment, pulmonary air leaks and chronic lung disease. Objective: This study aims to assess the effect of surfactant therapy in premature infants with respiratory distress syndrome at Intensive Care Unit of Children Hospital N\xb0.2. Subjects and method:A cases study about premature infants less than 24 hours after birth with respiratory distress syndrome (RDS) admitted to intensive care unit and treated with surfactant from January 2007 to July 2007 at the Children Hospital No 2. There were 30 cases recruited. The data was collected and analyzed by EpiInfo software 2002.Results: Most of them improved in respiration status after using surfactant (96.7%); no case of air leak was seen; 3 bronchopulmonary dysplasia cases and 4 deaths due to nosocomial infection were seen. Conclusion: Surfactant therapy was effective in premature infants with RDS. In the case of having economic advantages, surfactant may be indicated for preventive treatment on the premature and light weigh infants without respiratory distress syndrome on clinical aspect.
