The study was carried out on 27 patients with psoriasis and 9 heatlhy volunteers. Results showed no difference between IgA residues in various skin tissues of psoriasis patients. There is an increase of IgM residue in psoriasis lesions, but in healthy subjects there is not. In the lesions after the treatment and in the tissue without sporiasis, IgM residue is less than in the lesions before treatment. There is an increase of IgG residue in the lesion but in healthy skin there is not. IgG residue in healthy skin is less than in psoriasis. After the treatment, in psoriasis skin lesion, IgG is reduced slowly in comparing with that before the treatment C3 complement residue in the lesions is more than in healthy skin

The Vietnam Health Insurance was deploying the pilot method of liquidation and separating the hospital bursar for patients with the health insurance from the regulation of partial liquidation of hospital bursar, i.e from the liquidation according to the health service cost. It means that there must be the adjustment and correction of the regulations of government about the partial collection of the hospital bursar and liquidation mechanism of the health insurance budget

During 10 years from 1991-2000, the main communicable diseases are still existing as an important health problem in Vietnam. However, the trend has changed, particularly for vaccine preventable diseases. Poliomyelitis was eradicated by the year 2000. Neonatal tetanus has decreased below 1/1000 live births at the district level, therefore, it was eliminated in Vietnam. Pertussis has diminished under 0.4/100,000 population since 1994. Japanese encephalitis (JE) has been controlled in some districts where coverage of JE vaccineation was high. Cholera still occurs in Vietnam, but the morbidity rate has decreased under 0.85/100,000 inhabitants since 1996. Plague happens in the Central, Southern and High Plataeux region, but the number of cases and deaths have dramatically decreased
Communicable Diseases Epidemiology

From March 1999 to August 2000, 134 psoriasis patients were admitted in the Institute of Dermatological cases. Among then, male patients were 2,4 times higher than female, more concentrated at the age of 20-60 years old, with the age of onset from 20 to 40 years old and 7,46% had the family history of psoriasis, 35,8% had got the history of various chronical diseases and 23,1% had used the alcohol. The itching medicaments should be used in combining with sedative systemic corticosteroides were not recommended.

Background: Nha Trang city located in central Viet Nam, has had dramatic economic development in recent years. The economic development has also leads to changes in the environment. Previous studies showed that cancers were closely related to environmental factors, but there was no study on this issue in Nha Trang city. Objectives: The study aimed to describe the cancer cases that were recorded in the cancer registration and the related environmental factors in Vinh Luong commune and the three neighborhood communes of Nha Trang city. Subjects and method: 192 patients who were diagnosed with cancer in the provincial general hospital and other hospitals from 1/1/2000 to 30/9/2006 and have resided in 4 above communes. Water samples collected from 14 water-wells from these communes were tested for chemical pollution and bacteria index. 20 sites in Van Dang village were tested for radioactive pollution levels. Results: Average crude morbidity of cancer per 100,000 inhabitants per year in Van Dang village and Vinh Luong commune and in the 4 communes as a whole, were 64.9, 51 and 53.3, respectively. The rates for male and female were 65.0 and 41.0, respectively. The most common cancers in women were cervical and breast cancers (11.8% and 9.2%, respectively). For men, leading cancers were liver cancer (31.9%) and lung cancer (14.7%). Almost all of the water samples did not meet the hygiene standard for nitrate (NO3) and coliform. Natural radioactive levels in these 4 communes were normal. Conclusion: Van Dang village had the highest cancer prevalence per 100,000 habitants compared to the other villages of Vinh Luong commune, but it was still lower than that of some other provinces. Most of the water samples collected from the water-wells did not met standard for nitrate levels and coliform.

The foundations of nuclear medicine in Vietnam were established from 1970. Until now, after 48 years of development, in Vietnam, we have some basic equipment including 31 SPECT, 4 SPECT/CT machines, 11 PET/CT scanners, five cyclotrons, and one nuclear reactor.Many nuclearmedicine techniques in diagnosis and treatment have been routinely performed at provincial and central level health facilities such as tumor scintigraphy, thyroid scintigraphy, bone scintigraphy, kidney scintigraphy, cardiac scintigraphy, and radio-isotope therapy with I-131 and P-32. Selective internal radiation therapy with Y-90 microsphere and I-125 radioactive seed implantation has been also successfully applied in some big hospitals. However, there are still many difficulties for Vietnam as the lack of new widely used radioisotopes such as Ga-67, Cu-64, Samarium-153, and Lutetium-177 and the lack of nuclear medicine specialists. In the future, we are putting our efforts on the applications of new isotopes in diagnosis and treatment of cancers (theranostic) like Ga-68-DOTATATE, Lutetium-177-DOTATATE, Ga-68-PSMA, and Lutetium-177-PSMA, equipping modern nuclear medicine diagnostic tools, strengthening the human resources training in nuclear medicine. At the same time, we are trying our best to strengthen the cooperation with international nuclear medicine societies in over the world.

Background: Dengue virus infection is a major public health problem. A hypothesis put forward for severe dengue is the cytokine storm, a sudden increase in cytokines that induces vascular permeability. Previous studies and our recent meta-analysis showed that IL-6, IL-8, IFNγ, TNFα, VEGF-A and VCAM-1 are associated with dengue shock syndrome. Therefore, in this study we aim to validate the association of these cytokines with severe dengue. Methods & Findings: In a hospital based case control study in Vietnam, children with dengue fever, other febrile illness and healthy controls were recruited. Dengue virus infection was confirmed by several diagnostic tests. Multiplex Immunoassay using Luminex technology was used to measure cytokines simultaneously. A positive association with dengue shock syndrome was found for VCAM-1, whereas a negative association was found for IFNγ. Furthermore, the multivariate logistic analysis also showed that VCAM-1 and IFNγ were independently correlated with dengue shock syndrome. Conclusion: IFNγ and VCAM-1 were associated with dengue shock syndrome, although their role in the severe dengue pathogenesis remains unclear. Additional studies are required to further investigate the function of these cytokines in severe dengue.

Background: According to WHO, there are 5 million deaths from kinds of injury a year in the world, of which 875000 deaths occur in children under 18 years old. Injury leads to 40000 deaths which account for 10.7% deaths due to all other causes a year in VietNam. Objective: To show conclusions of the situation of child injury, recommendations for prevention of child injury and methods in order to enhance emergency activity in Vietnam. Subjects and method: The authors collected information about all patients who had emergencies due to injury at Viet Duc hospital, from March 26th 2006 to Octorber 26th 2006. However, supervised cases were the patients under 18 years old who were examined and treated at the Department of Emergency. Results: During the period of study, 2536 patients under 18 years old were examined for injury, of which death and coming back home for death were 83 cases (3.27%). 974 children had emergency resulted from injury: male was more than female: 697 verus 227. The leading causes of child injury were fall and traffic accident, respetively 34% and 60%. The most common traumas were traumatic brain injury (45%), limbs injury (41%). Although most of cases had first aid at the hospitals in district or province level, the rate of non-first aid cases was high (34%). Conclusion: Child injury is a leading cause of child death in hospitals. Methods for prevention of child injury should focus on educating and propagandizing to minimize injuries caused by traffic accident and fall.
