The capillaroscopy is a method to early diagnose the symptoms of capillary spasm in the vibration. Beside of usual microscope M- 70 A of Soviet Union, any microscope can be used to illuminate and take the photograph of the capillary of finger transnail skin fold.

A study on the shaking disease among coal miners in Quang Ninh was implemented by measurement of the shaking perception. The results found that the shaking perception of miners who have been working in coal mine for 5 years and over was significantly reduced compared with this of control. The test of shaking perception by diapason C128 is easy to use everywhere and has a specific significant for finding the shaking disease.

The study aimed to evaluate the local shaking level and noising level in coal miners of Mong Duong, Khe Cham, Thong Nhat and Mao Khe in 8/2001. The results have shown that the coal miners were affected by shaking of drilling hamper. The shaking level was 1.7 m/s2, higher allowed level. In addition to, they were affected by the noise that was higher than this of allowed level.

Background: Hemoglobin is a composition of erythrocyte. They are released from the lysis of erythrocyte. Objectives: to study free hemoglobin concentrations in surgical patients received massive blood transfusion (MBT). Subject and methods: 48 adult patients (male: 31 (64.6%), female: 17 (35.4%), mean age: 36 \xb1 16) with more than 3000ml of storage blood were tested for plasma free hemoglobin. The major reason for MBT were severe trauma (45.8%), the remainder were non - trauma. The change of Hb free was followed in 16 patients at the times of 1500 ml, 2000 ml, 3000 ml storage blood transfused (9 \xb1 3 days). Results: Plasma free hemoglobin was detected after 2,000ml of red cell transfusion and during the first 24h post MBT in 100% cases. Plasma free hemoglobin concentration trended to increase with quantity of transfused blood (0.56 \xb1 0.3 g/dl after 2000 ml, 0.76 \xb1 0.47 g/dl after 3000 ml, and 0.93 \xb1 0.41 g/dl after 5000 ml). There was no correlation between free hemoglobin concentration in plasma of patients with the storage time of blood transfused, and no difference of plasma free hemoglobin concentration between in trauma and non trauma patients. Conclusion: The blood with short time of storage is recommended after 1500ml blood transfusion in these patients. \r\n', u'\r\n', u'

Background: Massive Blood Transfusion is common in surgery, which can save many lives. However, massive blood transfusion in a short time together with other disorders can cause serious side effects and death. Objective: Investigation on the factors related to mortality in surgical patients after massive blood transfusion. Subject and Method: A descriptive study was carried out on 90 patients of massive blood transfusion in Viet Duc hospital. Results: There were 38 cases of death among the 90 patients of massive blood transfusion (42%), in which 97.7% died within 2 to 24 days of hospitalization (caused by multi organ failure). There are no correlation between the deaths, with the units of blood transfused, hypothermia, anemia (Hb) and with platelet counts, APTT, PT, fibrinogen changes, 3 risk factors that correlated significantly with mortality are BE, DIC and age of patients. Conclusion: Acidosis (pH, BE) and hemostasis status should be closely monitored and corrected early to reduce the risks of mortality.

From 1994 up to now, active measures in the prevention of cholera have been implementing in Thua Thien Hue province, by the proper investment for safe water supplying, waste treatment, sewage treatment, sanitary-food safety examination and control of chloride content in safe water system, close supervise and soon discovery of patients with cholera, quick and strict responding to the epidemic so that limiting and decreasing significantly the mortality.

A survey on malnutrition of under five years children was carried out in three different ecological areas of Thuan Thien - Hue: plain, mountain and coastal areas. Malnutrition is still high in the whole province, averaging 34,4%, and especially high in mountain areas with 59,7%.

For 4 years, Thua Thien - Hue province has been implemented 3844/1 PAM project in 45 communes. The results showed that: malnutrition rate of children under 5 years was reduced. The underweight malnutrition decreased from 49.6% to 37.1%; wasting malnutrition decreased from 56.8% to 45.7%. Mother's knowledge on nutrition has been improved.

137 patients with blunt renal trauma were examined by the sonography which can classify exactly 86.2% of renal injuries. Signs of the deformed kidney, of renal contour discontinuation and of the retroperitoneal hematoma were significantly for classification of renal injuries
