Nested polymerase chain reaction (nested PCR) was applied to idennify species composition of four human malaria parasite species in Thanh commune, Huong Hoa district of Quang Tri province. The pair of primers specific to each species of P.falciparum, P.vivax, P.malariae and P.ovale were used. AND fragments specific to each species was 18ssr-RNA)[5], [10]. The analysis of 152 blood samples showed only two species of malaria parasites of P.falciparum (71%) and P.vivax (29%) present in the study area. Single P.falciparum infection rate was 65.8%, single P.vivax infection rate was 16.4% and the double infection of P.falciparum and P.vivax was 17.8%

234 healthy persons aged from 16-70 (142 males and 92 females) measured ventilatory function were studied during 1994-1996 using Spiroanalyser ST 300 of Japan. The result: In men aged from 16-25, Coefficient A of regression equation of IVC, FVC, FEV1 was positive, meaning values of criteria increased according to age. In women, Coefficient A of regression equation of FVC, FEV1, MMF, PEF, V75, V50, V25, MVV was positive, their values increased according to age, except IVC and MEFR, their coefficient A was negative, decreased according to age. However in both sexes, these ventilatory function values increased according to high. In group of persons aged from 16-70 for both sexes, this values increased with high but decreased when age advanced

The comparison of the contrast medium X-ray of radical capsular with the results of operation of the lumbar spinal disc herniation showed that the diagnosis of the spinal disc herniation by the contrast medium X-ray was suitable with the results of the operation of the lumbar - spinal disc herniation in which the lumbar spinal disc herniation in the vertical of L4, L5, L5S1 and double herniation were 70.7%, 13.3% and 8.8%, respectively. The unsuitable rate of diagnosis between them was 5.7%. There were 11 cases that were the false negative due to press of extradural vein and the flaval ligament inflammatory. The X-ray technique should be implement in 3 positions: vertical, side and inclined 3/4 to prevent the missing of lesion

The authors investigated some factors that increase the risk of spreading HIV/AIDS. Subjects were persons with HIV/AIDS who were registered at AIDS Prevention and Control Office of Hoa Binh province. It was revealed that HIV/AIDS epidemic have been spreading rapidly. It has occurred mainly in young adult and most cases are males. People at high risk are injected drug users.

Cytomegalovirus is an opportunity virus involves in class of Herpes virus 5 (adenovirus) that causes disease in the patients with immune deficiency especially AIDS. CMV-caused retinitis occurred on 40% of AIDS patients with severe general condition. However, some patients with CMV-caused retinitis also show signs of early stage of AIDS. The study reported a case of 22-year male patient who admitted due to loss of vision. Serum test showed that the patient was high positive with HIV. The patients manifested retinal necrosis with hemorrhage and vasculitis, which was spreading from the optic disc in both eyes. Then he had uveitis in both eyes. This disease may cause irreversible retinal damage and permanent loss of vision. In the treatment, gancyclovir or foscarnet can be used effectively. These medications provided an improvement in clinical condition. But the disease can relapse if the medications are discontinued.

Application of PCR technique to survey component and mechanism of 4 human malaria parasites in Gia Lai province. These used bait couples were specificity for P.falciparum, P.vivax, P.malariae and P.ovale. The results showed that: there were the existance of 4 human malaria parasite species, of which P.falciparum was 57.6%, combination rate of 2,3,4 parasites species was 54.76%. To distinguish the recurrent, re-infection based on the difference of alleles in locus gen. 3 genes for highly polymorphic antigens: merozoite surface protein 1 (MSP1), merozoite surface protein 2 (MSP2), glutamate rich protein (GLURP). 11 patients were treated by fansidar had been recurrented after 14 days

A study on 48 patients with coronary artery diseases at Internal Medicine Department in Hue Central Hospital from July to December/1998. Results: Patients who live in urban: 62.5% and rural: 37.5%. The risk factors seen in study group is tobacco smoking (50%), hypertension (50%) and increased cholesterol level (40%). The average plasma fibrinogen level in 48 cases in control group is 11.07± 1.90µmol/l. A relative risk of fibrinogen plasma for coronary artery diseases is 3.18 (confidential interval (CI) 95%). Attribute risk is 0.65%, it means 65% case coronary artery diseases due to high plasma fibrinogen level. The incidence risk of coronary artery diseases increase 9.06 times in people with increase plasma fibrinogen level. So the routine test on plasma fibrinogen has value in prevention and predict coronary artery diseases.

Ischemic colitis (IC) is an underreported chronic disease characterized by the hypoperfusion of the bowel mucosa. The diagnosis and treatment may be challenging because its clinical course resembles other colitis or even colorectal malignancies. This paper reports an untypical case to underline the diversity of IC manifestation. A 68-year-old man with several comorbidities was admitted because of abdominal pain with a 6-month duration and a mass in the left lower quadrant. Colonoscopy revealed erosive pseudomembranous colitis narrowed colon segments with ulcerated mucosa mimicking colorectal cancer and inflammatory bowel disease. The stool cultures and Clostridium difficile toxin tests were negative. After the failure of conservative therapy, the Hartmann procedure with temporary ileostomy was performed uneventfully. The histological results of the surgical specimens revealed IC with focal pseudomembranous areas.

Background: According to statistical data of the Vietnam Ministry of Health, there were 124,223 people with positive HIV, 23,661 AIDS patients and 13,649 AIDS- related deaths up to April 30th 2007. The major transmission route is injection. Objectives: (1) To compare the characteristics of drug use in users with different time. (2) To describe the health issues and health service access of young male drug users. Subjects and method: A cross-sectional survey was carried out using a combination of medical anthropology and epidemiology methods. 1.115 young male drug users in Ha Noi between September 2004 and September 2005 were divided into 4 groups of the equivalence number, but with different drug using history. Results and conclusion: The newer drug users (within 2 years) started using drug later than the older ones, more of them started using by injecting; they transfer from smoking/sniffing to injecting as well as trying and using more different types of drugs together in shorter time than others. The proportion of HIV (+) infection in these people was higher, which states the necessity of intervention to help them enhance their knowledge to prevent HIV infection amongst themselves. Mental health care is also needed for drug users, the demand for mental health care increases with the time of drug usage.

Objective: To investigate airway volumes using cone-beam computed tomography (CBCT) by skeletal patterns, sex, and cervical vertebral maturation (CVM) stages in Korean adolescents. Methods: The sample consisted of pretreatment CBCT and cephalograms of 95 adolescents (aged 12–19) obtained out of 1,611 patients examined for orthodontic treatment from 2018 to 2020 in Kyungpook National University Dental Hospital. The samples were classified into two sex groups; three skeletal pattern groups, four chronological age groups and four CVM stages. Nasopharyngeal volumes (NPV), oropharyngeal volumes (OPV), total pharyngeal airway volume (TAV) and minimum cross-sectional area (MCA) measurements were taken from the CBCT. Multiple linear regression analyses to find out which one of the independent variables are good predictors for airway variables. Significant factors were analyzed by two-way multivariate analysis of variance (MANOVA) then multiple comparisons were analyzed using a t-test, and Fisher least significant difference. Results: Age, sex, CVM, and Sella-Nasion-B point have significant influence on airway variable. Males and females showed similar patterns of change in chronological age groups 1–3; however, males had larger NPV, OPV, and MCA at CVM in group 4. According to CVM stages, males had larger OPV, TAV, and MCA at CVM stage 6 (p-value: 0.019, 0.021, 0.015, respectively) and no sex differences at CVM stages 3, 4, and 5. Conclusions Skeletal patterns have an effect on airway volume. Sex differences were found in CVM 6.
