Previously in training programme for health workers, knowledge and practices of orthopedic and prosthesis aquipment were nephigible. The innovation in training had made difference. The projects had designed 4 programme of training and various new manuals for each subjects at different levels, the closed cooperation was implemented between MOH and the Ministm of Labor- invalid and Social affaires.

The study evaluated hand over knowledge and skill product orthosis and prosthesis for disabled people at communite acording to appropriate technology and evaluated quanlity of orthotics and prostheties, evaluated the effectiveness of them according to appropriate technology for disabled people in 17 last years. The result showed that: evaluating 192 community workers about knowledge for orthosis and prosthesis. There is about 70,83% in good mark, 24,41% in average, 4,76% in bad. 167/202 (82,67%) in control group were in bad mark. The different between 2 groups was significant. Price of the tool is cheap, quality of it is good. Rate of exercise improvement in 316 disabled people is 83,07% (control group is 7,38%).

Background: Dengue Fever/Dengue Hemorrhagic Fever (DF/DHF) has emerged as one of the most important public health concerns in Viet Nam in recent years. Key breeding containers plays an important role in driving dengue vector control in the public. Objectives: The research was conducted to discover the dengue situation, its vectors and key containers to make relevant recommendations in reducing effectively the vector population. Subjects and methods: Two hundred households in two communes of Nam Dinh province (100 in each studied commune) were selected randomly. Vectors collected from the field were identified using mosquito key. The number of dengue larvae and mosquitoes were directly counted or adjustment methods were used to estimate the true number in each type of water storage facility. Results: In Minh Thuan commune, Ae. albopictus larvae were mainly concentrated in jars (49%) and discards (59%), most of Ae. aegypti was found in cement tanks with a volume more than 500L (72%). In Trung Dong commune, larvae of Ae. albopictus concentrated in jars (40%) and discards (25%) and aquariums (15%), while most of the Ae. aegypti larvae was discovered in cement tanks with volumes more than 500L (86%). Mosquito density index of Ae. albopictus in Trung Dong and Minh Thuan communes was 0.56 and 0.38, respectively. The Aedes larvae, houses for larvae and Breteau index were nearly at the threshold of dengue epidemic occurrence for Ae. aegypti and over a certain threshold for Ae. albopictus. Some recommendations were provided to help reduce the dengue vectors. Conclusion: Investigation of key mosquito larvae in water containers was useful in driving the effective dengue vector control. Further studies are required to evaluate the impact and methods to manage water containers in the local area.

Background: In Vietnam, Dengue Fever/Dengue Haemorrhagic Fever (DF/DHF) is one of ten contagious diseases causing epidemics with the highest prevalence.\r\n', u'Objectives: To describe some characteristics of DF/DHF epidemic in Khanhhoa province in 2005. \r\n', u'Subjects and methods: The descriptive study based on available data obtained from the surveillance reporting system.\r\n', u'Results: Total reported cases were: 5.365 (morbidity rate = 469.58 per 100.000) and 4 deaths (CFR = 0,074%).446 of 1.661 Mac Elisa tested cases were positives (positively = 26.9%). The positive cases in male were higher than that in female. Almost all of the positive cases were less than 15 years of age. Virus serotype D1 and D2 were isolated in the epidemic. 5 of 7 districts (except 2 mountainous districts) had outbreaks. The epidemic started in April and stopped in December. Ninhhoa district was the first location of the outbreak and Vanninh district was the last one. Geographical distribution of the epidemic was as follows: costal communes=54.6%, delta communes = 30.3%, urban communes =15.1%. The epidemic level was medium (>20% - <50% of communes having the epidemic). "Pilot intervention communes" had 4 times the higher risk of DF/DHF than "non pilot intervention communes". \r\n', u'Conclusions: IEC activities for preventing DF/DHF should be strengthened. For maintaining the low mosquito and breutau index, we need routine preventive actions. Authorities need to consider and to consolidate the activities of Pilot intervention communes. Coastal communes should be supplied with running water. \r\n', u'\r\n', u'

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: s/Aims: Parenchymal-sparing anatomical hepatectomy (Ps–AH) based on portal ramification of the right anterior section (RAS) is a new technique to avoid unnecessarily transecting too much liver parenchyma, especially in cases of major anatomical hepatectomy. Methods: We prospectively assessed 26 patients with primary hepatic malignancies having undergone major Ps–AH based on portal ramification of the RAS from August 2018 to August 2022 (48 months). The perioperative indications, clinical data, intra-operative index, pathological postoperative specimens, postoperative complications, and follow-up results were retrospectively evaluated. Results: Among the 26 patients analyzed, there was just one case that had intrahepatic cholangiocarcinoma The preoperative level of α– Fetoprotein was 25.2 ng/mL. All cases (100%) had Child–Pugh A liver function preoperatively. The ventral/dorsal RAS was preserved in 19 and 7 patients, respectively. The mean surgical margin was 6.2 mm. The mean surgical time was 228.5 minutes, while the mean blood loss was 255 mL. In pathology, 5 cases (19.2%) had microvascular invasion, and in the group of HCC patients, 92% of all cases had moderate or poor tumor differentiation. Six cases (23.1%) of postoperative complications were graded over III according to the Clavien–Dindo system, including in three patients resistant ascites or intra-abdominal abscess that required intervention. Conclusions Parenchymal-sparing anatomical hepatectomy based on portal ramification of the RAS to achieve R0-resection was safe and effective, with favorable short-term outcomes. This technique can be used widely in clinical practice.

Background: Melaleuca essential oil has many good effects, bringing economic efficiency; however, low extraction efficiency is a problem that needs to be overcome. This study aims to enhance the efficiency of extracting Melaleuca essential oil by employing deep eutectic solvents (DESs). Materials and methods: Branches and leaves of Melaleuca cajuputi Powell were pretreated by DESs. Carry out the distillation of essential oils by steam distillation. Determination of the chemical composition of essential oils by chromatography-mass spectrometry (GC-MS). Results: The combination of choline chloride and oxalic acid to create DESs solvent system helps the extraction efficiency of Melaleuca essential oil increase by 160%. In addition, the total content of 1,8-cineol and isocineol in the essential oil extracted with DESs solvent was 34.019%, higher than that of the essential oil extracted with distilled water at 30.749%. Conclusions: The positive results show the potential of using DESs solvents to improve the yield and quality of Melaleuca essential oil
