Background: Gougerot-Sj\xf6gren syndrome is an autoimmune disorder with two remarkable symptoms such as dry eyes and dry mouth. Objective: To study the symptoms of dry mouth of Gougerot-Sj\xf6gren syndrome after rheumatoid arthritis; To evaluate clinical and subclinical manifestations of dry mouth. Subjects and method: A prospective, descriptive, cross-sectional study included 160 patients with rheumatoid arthritis, who treated at Department of Rheumatology of Bach Mai hospital, from 1998 to 2003. The patients were divided into 2 groups: 60 patients with Gougerot-Sj\xf6gren syndrome and 100 patients without Gougerot-Sj\xf6gren syndrome. Results: The average age of patients with Gougerot-Sj\xf6gren syndrome was 54.55 \xb1 10.91 years. The mean time of having dry mouth was 8.65 \xb1 8.39 months. Clinical manifestations of dry mouth were sensation of dry mouth (90%), lost of saliva (80%), drink a lot of water while eating (58.3%), enlargement of parotid glands (15%). Degrees of dry mouth were mild and moderate (36.7%), severe (53.3%). 93.3% of patients decreased total salivary flow.82% of patients had 3 and 4 anatomopathologic stages according to Chilsom classification. Conclusion: Incidence of symptoms of dry mouth was higher significantly in the rheumatoid arthritis patients with Gougerot-Sj\xf6gren syndrome than those without Gougerot-Sj\xf6gren syndrome.

Background: Tophi is an important symptom of chronic gout. Objective: To assess clinical characteristics of topbi and its relationships with other manifestations of chronic gout. Subjects and method: A study was conducted in 65 patients diagnosed chronic gout based on Bennett and Wood criteria 1968, with tophi, treated at Department of Rheumatology, Bach Mai hospital, from December 2003 to June 2004. This was a retrospective, prospective, cross-sectional study. Results and conclusions: All patients were males and the average age was 57.8 \xb1 11.71 years. 72.3% of patients aged from 30 to 59 years. The average time of occurrence of tophi in chronic gout was 7.73 years. The mean number of tophi was 24.8 \xb1 9.4 (ranged from 1 to 70). Erosion of tophi occurred 25%. 92.9% of patients had distribution in inferiors limbs and 80.4% had superior limbs. There were relationships between number of tophi and renal lesions, distribution of tophi and number of painful joints.

Capillary Zone Electrophoresis (CZE) was used to quantify ketoprofen in 50mg ketoprofen capsules and ketoprofen gel 2.5%. The results were compared to results of spectrophotometric UV-VIS method. Results: the accuracies of 2 methods were different but not significant. Results of CZE method were rather lower than spectrophotometric UV-VIS method because impurities were separated in electrophoresis process. The authors concluded that CZE could be used to quantify ketoprofen in products

A study on 90 people ( 62 male and 30 female) who had history of bone fracture due to serious trauma was conducted in Friendship Hospital. The result showed that: the age and BMI is equivalent between two groups. The bone mineral density in males is higher than that in females, the bone mineral density is highest on neck of femur and lowest on trochiter. The rate of osteomalacia on the upper part of femur was 31.5%. The density of the neck of femur in male group is higher than female ones. Weight, BMI and sport playing are factors related to crease bone density. Age, smoking and alcohol drinking are factors that lessen the bone density. For the elders, it is nesesay to measure the bone density in order to have preventive methods and appropriate treatment, avoid bone facture later.

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

Previous papers have reported that polyphenols from green tea (Camelia sinensis L.) were useful for controlling dental caries. This study examined the effects of the ethanol total polyphenol extract (CX) of green tea leaves on dental caries causing Streptococcus mutans. CX showed to inhibit the glycolysis, biofilm formation and respiration of S. mutans. At the concentration of 0.05%, CX suppressed 30% oxygen consumption in glucose excessive medium, totally inhibited NADH oxidase activity and killed the bacteria with D value of about 13 minutes. The combination of 0.025% CX and 0.25 mM NaF blocked pH drop during glycolysis. Polyphenols from green tea leaves inhibited therefore the adherence of S. mutans in vitro and proved to be effective against dental caries.
