Objective: To evaluate the effectiveness and safety of electroacupuncture in conjunction with additional medications in providing analgesia and stabilizing hemodynamic parameters during total thyroidectomy. Methods: This randomized controlled trial included 100 patients who underwent a total thyroidectomy between October 2022 and October 2023 at the Vietnam National Hospital of Acupuncture. The patients were randomized into two groups. The electroacupuncture analgesia (EA) group received EA stimulation at five acupuncture points: Hegu (LI 4), Neiguan (PC 6), Shuitu (ST 10), Quepen (ST 12), and Yifeng (SJ 17), while the control group received a bilateral superficial cervical plexus block. Primary outcomes included the level of analgesia and perioperative vital signs in both groups. Additionally, pain thresholds and serum β-endorphin levels were measured before and after electroacupuncture in the EA group. Results: Complete analgesia (Level A) was attained in 86% and 76% of the patients in the EA and control groups, respectively, with no significant difference between the two groups (P = 1.00). In the EA group, the mean pain threshold after receiving EA doubled (648.7 (77.4) g/s vs. 305.3 (45.3) g/s, P < .001), and the mean serum β-endorphin level increased by approximately 13.5 pg/mL (P < .001). All patients remained hemodynamically stable throughout the surgery. Conclusion EA, in conjunction with additional medications that stimulate five acupuncture points, LI 4, PC 6, ST 10, ST 12, and SJ 17, was well tolerated and effectively maintained a suitable level of analgesia and hemodynamic stability during total thyroidectomy.

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.

Purpose: Odontomas represent a common clinical entity among odontogenic tumors, but are not well-addressed in the Vietnamese population. The present study aimed to determine the clinical and preclinical characteristics of odontomas and associated factors in the Vietnamese population. Materials and Methods: This retrospective study retrieved data from histopathological diagnoses from 2 central hospitals of Odonto-Stomatology in Ho Chi Minh City, Vietnam during 2004-2017. The odontomas were classified as complex (CxOD) or compound (CpOD) subtypes. The epidemiological, clinical, and radiological characteristics of the odontomas, stratified by subtype and sex, were obtained and analyzed. Results: Ninety cases, consisting of 46 CxODs and 44 CpODs, were included. The average age of patients was 32.4 (±20.2) years. The patients with CxOD were older than those with CpOD (P<0.05). Clinically, 67% of patients showed an intraoral bone expansion. Approximately 60% of patients with CxOD exhibited a painful symptom, about 3-fold more than those with CpOD (P<0.05), whereas almost all patients with CpOD exhibited perturbations of dentition, unlike those with CxOD (P<0.05). Radiologically, CxOD was characterized by a larger dimension than CpOD in both sexes (P<0.05), and CpOD induced complications in adjacent teeth more often than CxOD (P<0.05). The development of odontoma with advancing age differed significantly in odontoma subtypes related to their pathological origins, and between the sexes, resulting from different physiological states. Conclusion The findings of this study highlight the value of clinical and radiological features of odontomas and their associated factors for the early diagnosis and adequate treatment of younger patients.

Purpose: Laparoscopic surgery is considered a promising approach for Hartmann reversal but is also a complicated major surgical procedure. We conducted a retrospective analysis at a city hospital in Vietnam to evaluate the treatment technique and outcomes of laparoscopic Hartmann reversal (LHR). Methods: A colorectal surgery database in 5 years between 2015 and 2019 (1,175 cases in total) was retrieved to collect 35 consecutive patients undergoing LHR. Results: The patients had a median age of 61 years old. The median operative time was 185 minutes. All the procedures were first attempted laparoscopically with a conversion rate of 20.0% (7 of 35 cases). There was no intraoperative complication. Postoperative mortality and morbidity were 0 and 11.4% (2 medical, 1 deep surgical site infection, and 1 anastomotic leak required reoperation) respectively. The median time to first bowel activity was 2.8 days and median length of hospital stay was 8 days. Conclusion When performed by skilled surgeons, LHR is a feasible and safe operation with acceptable morbidity rate.

Antibiotic resistance is the most important factor leading to the failure of eradication regimens. This review focuses on the prevalence of Helicobacter pylori primary and secondary resistance to clarithromycin, metronidazole, amoxicillin, levofloxacin, tetracycline, and multidrug in Vietnam. We searched the PubMed, EMBASE, Vietnamese National Knowledge Infrastructure, and Vietnamese Biomedical databases from January 2000 to December 2016. The search terms included the following: H. pylori infection, antibiotic (including clarithromycin, metronidazole, amoxicillin, levofloxacin, tetracycline, and multidrug) resistance in Vietnam. The data were summarized in an extraction table and analyzed manually. Finally, Excel 2007 software was used to create charts. Ten studies (three studies in English and seven in Vietnamese) were included in this review. A total of 308, 412, 523, 408, 399, and 268 H. pylori strains were included in this review to evaluate the prevalence of H. pylori primary resistance to amoxicillin, clarithromycin, metronidazole, levofloxacin, tetracycline, and multidrug resistance, respectively. Overall, the primary resistance rates of amoxicillin, clarithromycin, metronidazole, levofloxacin, tetracycline, and multidrug resistance were 15.0%, 34.1%, 69.4%, 27.9%, 17.9% and 48.8%, respectively. Secondary resistance rates of amoxicillin, clarithromycin, metronidazole, levofloxacin, tetracycline, and multidrug resistance were 9.5%, 74.9%, 61.5%, 45.7%, 23.5% and 62.3%, respectively. In Vietnam, primary and secondary resistance to H. pylori is increasing over time and affects the effectiveness of H. pylori eradication.

Ultrasonic computed tomography based on back scattering theory is the most powerful and accurate tool in ultrasound based imaging approaches because it is capable of providing quantitative information about the imaged target and detects very small targets. The duple-frequency distorted Born iterative method (DF–DBIM), which uses density information along with sound contrast for imaging, is a promising approach for imaging targets at the level of biological tissues. With two frequencies f₁ (low) and f₂ (high) through Nf₁ and Nf₂ iterations respectively, this method is used to estimate target density along with sound contrast. The implications of duple-frequency fusion for the image reconstruction quality of density information along with sound contrast based ultrasound tomography have been analyzed in this paper. In this paper, we concentrate on the selection of parameters that is supposed to be the best to improve the reconstruction quality of ultrasound tomography. When there are restraints imposed on simulated scenarios to have control of the computational cost, the iteration number Nf₁ is determined resulting in giving the best performance. The DF–DBIM is only effective if there are a moderate number of iterations, transmitters and receivers. In case that the number of transducers is either too large or too small, a result of reconstruction which is better than that of the single frequency approach is not produced by the implementation of DF–DBIM. A fixed sum N(iter) of Nf₁ and Nf₂ was given, the investigation of simulation results shows that the best value of Nf₁ is [N(iter)/2 − 1]. The error, when applying this way of choosing the parameters, will be normalized with the reduction of 56.11%, compared to use single frequency as used in the conventional DBIM method. The target density along with sound contrast is used to image targets in this paper. It is a fact that low-frequency offers fine convergence, and high-frequency offers fine spatial resolution. Wherefore, this technique can effectively expand DBIM's applicability to the problem of biological tissue reconstruction. Thanks to the usage of empirical data, this work will be further developed prior to its application in reality.

Background: Acute Respiratory Infection (ARI) is a common disease in developing countries. Morbidity and mortality of ARI are high, especially among children under 15 years old. Objectives: To describe socio-graphic factors, seasonal patterns, risky areas and determine the morbidity and mortality rates of acute respiratory infections in Thai Binh province. Subjects and method: This retrospective study reviewed the medical records of 4,585 hospital admitted patients who were diagnosed with ARI including upper and lower respiratory infections such as sore throat, pharyngitis, bronchitis, pneumonia and bronchitis-pneumonia at 8 district hospitals and 1 provincial hospital in Thai Binh province during 2002-2005. The selected medical records were based on the available check list and two standard screening tests. Results:Morbidity and mortality of ARI in Thai Binh province were 61.6 and 0.52, respectively. ARI mainly occurred among children under 5 years old, of which the highest mortality was among those under 12 months of age. Male children were at higher risk of acquiring ARI, but less prone to death than female. Occupation did not significantly associate with the risk of ARI. The morbidity increased sharply during inter-season, e.g. March and October. Thai Binh city, Kien Xuong and Tien Hai district were reported with the highest morbidity in accompany of the high mortality as consequences. Conclusion: The prevention and control methods were recommended to annually focus on the male children aged less than 5 years old during March and October in Thai Binh city, Kien Xuong and Tien Hai district.

Background: Child health care practices in the context of households and community is an important factor to improving the health of children. Some indexes were proposed by the World Health Organization to evaluate these practices. Objectives: To describe the knowledge and practice of pregnant women, under-5-year-old children\u2019s health care and assess the application of the survey toolkit in evaluating various indexes of healthcare practice at family and community levels. Subjects and method: By employing a structured interview, this cross-sectional survey has been conducted in Tu Liem district - Hanoi city and Tien Hai district \u2013 Thai Binh province. 120 mothers of under-5-year-old children participated in the survey. Results:98% of mothers had at least 3 antenatal visits during pregnancy. The rate of complete tetanus vaccination reached 43.3% in Tu Liem and 65% in Tien Hai. Prevalence of infant with low birth weight for age accounted for 8.3% in both districts. The percentage of children given complementary feeding at age of 6 to 9 months as the National Nutrition Program recommendations was only 30%. 65.7% and 68.5% of under-2-year-old children in Tu Liem and Tien Hai were breastfed within the first 30 minutes after delivery. There were a small proportion of mothers who gave complementary food either too early or too late, 8.3% and 8.4% in Tu Liem, 6.7% and 6.6% in Tien Hai, respectively. More than 90% of children were given normal feeding as usual during last their illness, but only 50% of children were given more fluid than usual. 98.2% of mothers knew 2 signs to immediately bring the child to health facilities. The most common injuries in under-5-year-old children were animal bites (62.5%) and falling (31.3%), however only 62.5% of mothers knew at least two measures of injury prevention. Conclusion: The toolkit for collecting data of practical index assessment can be applied at communes.
