Dengue; Dengue haemorrhagic fever investigation on 1000 households in Quang Ngai province showed that Ae.aegypti was the main vector, although Ae. Albopictus had been seen. Among mosquito larvae containing water tanks was the highest rate (40,36%). Mesocyclops had discovered in water tank community's awarness on Dengue haemorrhagic fever vector prevention had been increased, however propaganda on vector, mosquito and prevention measures are also needed.

Background: Training community-oriented general practitioners with the aims to provide the medical knowledge and skills of working in the community for medical students is appropriate with the socioeconomic context in Vietnam. Objectives: To evaluate the acceptance of the community in two districts Kim Bang (Ha Nam province) and Dong Hy (Thai Nguyen province) on field training for medical students. Subjects and method: The cross - sectional study was carried out on 300 households that were chosen randomly from 2 rural districts on April 2006. The heads of households were interviewed by open - ended questionnaires. Another 120 key informants from these two districts were invited to participate in a focus group discussion. Results: 81% of households voluntarily participated in the organization of field training for the medical students. More than 97% households paid attention to the medical students\u2019 information about health care and environmental hygiene. With medical community-based education, the people from communities receives\u2019 improvement in their knowledge of child care and personal hygiene in order to prevent diseases. Conclusion: Being exposed to health problems in communities, medical students can enhance their working and communication skills. People in the communities had a chance to improve their knowledge of disease preventions.

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: s/Aims: Pancreaticoduodenectomy (PD) is the only radical treatment for periampullary malignancies. Superior mesenteric artery (SMA) first approach combined with total meso-pancreas (MP) excision was conducted to improve the oncological results.There has not been any previous research of a technique that combines the SMA first approach and total MP excision with a detailed description of the MP macroscopical shape. Methods: We prospectively assessed 77 patients with periampullary malignancies between October 2020 and March 2022 (18 months). All patients had undergone PD with SMA first approach combined total MP excision. The perioperative indications, clinical data, intra-operative index, R0 resection rate of postoperative pathological specimens (especially mesopancreatic margin), postoperative complications, and follow-up results were evaluated. Results: The median operative time was 289.6 min (178−540 min), the median intraoperative blood loss was 209 mL (30−1,600 mL).Microscopically, there were 19 (24.7%) cases with metastatic MP, and five cases (6.5%) with R1-resection of the MP. The number of lymph nodes (LNs) harvested and metastatic LNs were 27.2 (maximum was 74) and 1.8 (maximum was 16), respectively. Some (46.8%) patients had pancreatic fistula, but mostly in grade A, with 7 patients (9.1%) who required re-operations. Some 18.2% of cases developed postoperative refractory diarrhea. The rate of in-hospital mortality was 1.3%. Conclusions The PD with SMA first approach combined TMpE for periampullary malignancies was effective in achieving superior oncological statistics (rate of MP R0-resection and number of total resected LNs) with non-inferior short-term outcomes. It is necessary to evaluate survival outcomes with long-term follow-up.
