Regarless age, occupation, health conditions, property; married men living in the Commune An Lac, District of Chi Linh, Hai Duong Province; Hoang Tay, Kim Bang, Ha Nam province; Dong Thap provincial town and Hanoi No1 College of Agriculture, were included in this horizontal investigation with a form of questionary. Results were processed medical statistic. Among 746 married men of 18 years and elder age, represented of the South, the North, urban and rural areas, intelligency and plain working person, there is a rate of impotentia of 15.7%, with a frequency of intercourse of 3,1072,16 times weekly, immediately after the marriage. The mean age of impotentia is 40,889,48 (p<0.01). In 47,5% of men, there is a nocturnal pollution, this rate is 36,7% in impotentia patient, and the rate of wet dream is 10,8%

Interview about sexual activity has been performed in 764 male subjects from 20 to 65 years old at 4 areas: Kimbang (Ha nam province), Chi Linh (Hai duong province), Cao Lanh (Dong Thap province), and University of Agriculture No1 (Hanoi). Results have shown that the prevalence of impotence is 15.7 percent, while sexual activity is decreased in 58.37 percent. The impairment of sexual activity is increasing with age and usually starting at ³40 years old (p<0.001). Sexual activity depends on occupation and work load and is decreased in smokers, alcohol consumers. In familial relationship, the decrease of sexual activity depends on female behavior and the number of children. In sum, it can be concluded that such factors as work load, anorexia, excess consumption of alcohol and stressful situation can be the cause of decreased sexual activity.

This is a report of 2 cases of human hydatidosis caused by Echinococcus ortleppi in Vietnam. The patients were a 12-year-old male (case 1) having a cyst of 10.0×9.0 cm size in the lung and a 50-year-old female with a 3.0×3.3 cm-sized cyst in the heart. Eosinophilia was 33.7% in the male and 45.8% in the female patient. C-reactive protein was increased to 16.5 mg/L in the male and 18.2 mg/L in the female. Both patients were positive for ELISA at OD=2.5 and 3.1, respectively. Echinococcus protoscolices were collected from the cysts by amniocentesis and surgery. The protoscolices were identified as E. ortleppi by morphology and analysis of mitochondrial NADH dehydrogenase 1 (nad1) gene sequence. Both patients were cured by surgical resection of the hydatid cyst combined with albendazole medication. The E. ortleppi infection in lung is the second report, and the other in the heart is the first in Vietnam.

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.
