Management of male infertility is one of urological activities at Binh Dan hospital. Since last year some advanced techniques have been applying to practice: Measurement of testicle volume levels of FSH, LH, Testosterone and Prolactine, transurethral ultrasound, selective testis biopsy, per - operative vasogram, resection of the verumontanum and vassal microsurgical by pass. Therefore, we could effectively differentiate two groups of substructive and non-obstructive infertilities and hence, prognosis and treatment could be better made. 487 patients have been seen, 54% of these has shown a non-obstructive infertility, 19% of obstructive cases and 27% of indiopathic cases. 37% patients have been followed-up with spermiogram improvement in 43% of those patients, and pregnancy rate was 12%. Ejaculative duct obstruction is rare, but not difficult to be confirmed, and its treatment has been proved as a simple but effective treatment

Nguyen Thanh Nhu has made a modified trocar: The Saigon trocar (patent pending) easy to be made in Vietnam, easy to use, safe, easy to maintenance and sterilisation, used with a 18F Foley catheter. We have performed cystostomies by using the Saigon trocar to put Foley catheters of 18F for 70 patients and by open surgery to put Foley catheters of 22F for 40 patients at Binh Dan hospital and 115 People Hospital in 1999. No operative complication has been recorded for trocar cystostomy: however, 7 failed cases because the procedure has not been carried out properly, had to be switched to open surgery. Using the Saigon trocar to perform suprapublic cystostomy reduces significantly procedure time and post-operative days, therefore the treatment cost is reduced (roughly 500000 VND/case). To prevent from complications, the procedure must be right indicated and done with good care (bladder volume >330ml, puncture perpendicularly to the abdominal wall).

Nowadays enlargement of information helped patients with erectile dysfunction to seek easily suitable treatment. Although there are not optimal method for the disease yet, but there were many important progress specially enzyme inhibitor PDE-5. Vardenafil has more advantages than PDE-5 because of its efficacy and indications. Although non-specific treatments (by oral drug, injection, surgery) have effect in most of erectile dysfunction but it is necessary to use specific treatments (sexual mentality consultancy, endocrine therapy…) for patients, too. Surgery plays important role in the treatment of erectile dysfunction

Background: In many years, National Institute of Malariology, Parasitology and Entomology conducted collection, storage and preservation of malaria parasites species \r\n', u'Objective: to evaluate some results of malaria parasite species collected from Daknong province and analysis of drug resistance in P.Palciparum by the polymerase chain reaction.\r\n', u'Subject and method: Malaria parasite species collected from Daknong province in 2006. Thirty-five isolates were confirmed to be resistant with chloroquin by in vitro test. Polymerase chain reaction-restriction fragment leng polymorphism were used. \r\n', u'Results: 55 Plasmodium jalciparum. 7 Plasmodium vivax. 4 Plasmodium malariae. 1 Plasmodium ovale samples were collected from the malaria patients. A preliminary analysis of drug-resistant mutations in the Plasmodium jalciparum chloroquine resistance transpory (pfcrt) and P Jalciparummulti-drug resistant genes showed that the change of the order of amino-acid of Plasmodium jalciparum was closely correlated to chloroquine resistance in 35 isolates at the mutant allele 76 of pfcrt gene of chloroquine resistant Plasmodiuntjalciparum isolates. \r\n', u'Conclusion: These results contributed to supplement malaria parasite species that were stored in National Institute of Malariology, Parasitology ad Entomology.\r\n', u'

Background: WHO recommends that malaria drug should be used with essential elements which are derivatives of artemisinin (ART) for treatment phase and limit the development of parasite (MIC). Objective: To assess in vitro effect of artemisinin powder and 10 alpha- trifluoro methyl hydroartemisinin (TEMHA) in powder and tablet form to P.falciparum. Subject and Method: 48h in vitro test of Phuc Nguyen Dinh was applied to this study. Results and Conclusions: The results showed that: for T996, IC50 values of ART, 10 alpha- TEMHA powder and 10 alpha- TEMHA pill were as follows: 37.8; 16.4 and 17.6 nM/L, respectively. For K1, IC50 values of ART, 10 alpha- TEMHA powder and 10 alpha- TEMHA pill were: 22.8; 11.4 and 12.2 nM/L, respectively. MIC values of artemisinin powder, 10 alpha- TEMHA powder and pill for T996 were as follows: 100; 40 and 40nM/L, respectively. For K1, MIC values of ART, 10 alpha- TEMHA powder and pill are: 76; 24; 32 nM/L, respectively.

Objectives: The prevalence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association. Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnamfrom December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (usingthe 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions. Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD.Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.63–2.12; p < 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p = 0.001). Compared to those without long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p = 0.001). Conclusion Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.

Objectives: Online misinformation has reached unprecedented levels during the coronavirus disease 2019 (COVID-19) pandemic. This study analyzed the magnitude and sentiment dynamics of misinformation and unverified information about public health interventions during a COVID-19 outbreak in Da Nang, Vietnam, between July and September 2020. Methods: We analyzed user-generated online information about five public health interventions during the Da Nang outbreak. We compared the volume, source, sentiment polarity, and engagements of online posts before, during, and after the outbreak using negative binomial and logistic regression, and assessed the content validity of the 500 most influential posts. Results: Most of the 54,528 online posts included were generated during the outbreak (n = 46,035; 84.42%) and by online newspapers (n = 32,034; 58.75%). Among the 500 most influential posts, 316 (63.20%) contained genuine information, 10 (2.00%) contained misinformation, 152 (30.40%) were non-factual opinions, and 22 (4.40%) contained unverifiable information. All misinformation posts were made during the outbreak, mostly on social media, and were predominantly negative. Higher levels of engagement were observed for information that was unverifiable (incidence relative risk [IRR] = 2.83; 95% confidence interval [CI], 1.33–0.62), posted during the outbreak (before: IRR = 0.15; 95% CI, 0.07–0.35; after: IRR = 0.46; 95% CI, 0.34-0.63), and with negative sentiment (IRR = 1.84; 95% CI, 1.23–2.75). Negatively toned posts were more likely to be misinformation (odds ratio [OR] = 9.59; 95% CI, 1.20–76.70) or unverified (OR = 5.03; 95% CI, 1.66–15.24). Conclusions Misinformation and unverified information during the outbreak showed clustering, with social media being particularly affected. This indepth assessment demonstrates the value of analyzing online “infodemics” to inform public health responses.
