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.

During working in hospital, the health staffs must expose to many risk factors for their health, including microorganism, medical equipment, patient's excretions, radioactive machines, noise, working position, chemicals, drugs and stress. There were no measures of prevention and improvement to completely eliminate the bad impacts of the work. Therefore, it is difficult to prevent the occupational diseases for health staffs.

A study of 284 patients with tuberculous pleural effusions cytologically diagnosed by smears stained with giemsa common method allowed distinguishing two groups: typical and untypical patients. Typical tuberculous pleural effusions were characterized by the presence of lymphocytes, typical characterized by the presence of lymphocytes, typical Langhans and/or epithelioid cells, typical caseum and other products and a few number of neutrophils. Untypical tuberculous pleural effusions were marked by the preponderance of lymphocytes, the complete degeneration of neutrophil, the presence of macrophages, lipophages, untypical Langhans and epithelioid cells, and of minor but clear caseum and other degeneration elements, no common bacteria on smears. With these criteria, the true of cytodiagnosis in comparison with histophatology was 80%.

Two patients have undergone to myocardial revasculairisation with venous segments, removed from the lower leg. In one patients, two anastomosis has been performed (left anterio-descending artery and first diagonal branch). In the another, the anastomosis has been completed by continuous over and over suture on the left anterior descending artery, obtuse marginal artery and left postero-lateral branch. There are no morbidity and operative mortality.

The safety and effectiveness of preventive antibiotherapy in appendicectomies were studied in the Dep. of Surgery, Khanh Hoa province hospital. A prospective study was carried out in 1999 for a sample of 235 cases of appendicitis of which 107 patients were assigned as control group, and 128 as case group. The preventive and therapeutic antibiotherapy were indicated for 2 groups, respectively. The results were reported as follows: good: 95.3%, bad: 0% for the case group as compared with 94.4% and 0.9% for the control group. The mean duration by days were 5.14 +/- 1.13 and 5.64+/-1.49 respectively. The mean cost of antibiotics used for each patient were 88,297 VND and 257,278 VND for each group. A conclusion was set that for our present hospital environment, preventive antibiotherapy is necessary and cost-effective; and can be applied for all clean- contaminated surgical operations for the purpose of lowering the health cost and at the same time to ensure the safety and to bring out good results of surgical interventions.
