Introduction: Carpal tunnel syndrome (CTS) is one of the most common peripheral neuropathies affecting patients' life. Performing endoscopic carpal tunnel release is now a new technique that is being gradually applied in Vietnam. This paper seeks to investigate the effectiveness of Chow’s method for CTS treatment. Materials and methods: This is a prospective cohort study involving seventy-seven patients with CTS who underwent Chow’s endoscopic method at our hospital from March 2019 to January 2020. The Boston Carpal Tunnel Questionnaire and electromyography (EMG) were used primarily to evaluate surgical decompression pre-operatively, one week, three weeks, three months, and six months after surgery. We also recorded incision length, pain at the scar, the improvement of symptoms and thenar atrophy and return-towork time after surgery. Results: A total of 85.7% of the patients were women. A moderate severity of EMG was seen in 64.9% of cases. Sixmonth post-operative functional status scale (FSS) (1.05±0.1) and symptom severity scale (SSS) (1.05±0.1) showed significant improvement when compared with preoperative FSS (2.8±0.5) and SSS (3.2±0.5). Post-operative EMG showed the distal sensory latency (DSL) and distal motor latency (DML) had returned to the norm in 88% and 89.3%, respectively. The average incision length was 12.1±1.2mm. Six months after surgery, numbness and hand pain had resolved in 97.4%, a painless scar was seen in 94.7%, but full recovery of thenar atrophy was only seen in 9.1%. Patients could get back to work after 10.2±2.4 days. Conclusion: Chow’s endoscopic carpal tunnel release is a safe and effective procedure for patients suffering from carpal tunnel syndrome that showed promising outcomes on clinical symptoms and functions on EMG with minimal pain and scarring, and early return to work.

Background: Like other countries in the world, Vietnam has seen the appearance of many infectious diseases such as SARS, influenza A/H1N1. Therefore, monitoring and quick response to infectious diseases, increasingly require enhancing the capacity of test systems. \r\n', u'Objectives: To determine the capacity for microbiological diagnosis and etiology of communicable diseases at the provincial centers for preventive medicine.\r\n', u'Subjects and methods: With the application of the cross-sectional approach, the study was conducted on microbiology diagnostic capacity for communicable diseases surveillance and response system in 55 Provincial Preventive Medicine Centers (PPMCs)\r\n', u'Results: Laboratory testing and confirmation (isolation and bio-chemical tests, gram stain) are only available for common nitrobacteria such as Escherichia coli, Vibrio cholera, Shigella, Salmonella, and some of the respiratory bacteria as streptococcus, meningococcus, etc... in most PPMCs. ELISA/MACELISA technique for detecting virus pathogen such as Arbo viruses (Dengue, Japanese B encephalitis) and Hepatitis B, HIV is also a focus of these PPMCs. However, for diseases caused by other viruses like Polio, Rota, measles, influenza, PPMCs have only the ability to collect specimens. \r\n', u'Conclusions: Most of the cases reported in the surveillance reports are based on clinical signs, only. Case confirmation was done by hospital/regional or national laboratory. \r\n', u'\r\n', u'

Background: Cervical cancer is one of the leading cancers in women worldwide.\r\n', u'Objectives: To evaluate the knowledge, attitude and practice towards cervical cancer and its preventive measures among the parents of young adolescent girls. \r\n', u'Subjects and methods: The cross-sectional survey was conducted in Tuliem District, Hanoi and Cu Chi District, Ho Chi Minh city. By employing a structured interview there have been 218 fathers/mothers of young adolescent girls at secondary school age (11to14 years old) participated in the survey. \r\n', u"Results: There was a limitation in the respondents' understanding about cervical cancer. Although 83% parents have been aware of cervical cancer and 89% considered it as a fatal disease, nearly a half of them does not know any symptoms of the disease. Similarly, inadequate knowledge on causes and risk factors of the disease has been common among respondents. Only 25% of parents are aware of HPV and few knew about the transmission route of this virus. HPV vaccines are still very new for parents. Only 29.8% of interviewees have heard about HPV vaccines. However, 74.3% parents have expressed a wish to have their daughters vaccinated, once HPV vaccines are introduced in Vietnam. \r\n", u'Conclusions: Knowledge, attitude and practice towards cervical cancer among parents of young adolescent girls in these district were quite limited\r\n', u'\r\n', u'

Aims: This study aimed to isolate the fungal strains causing brown spot disease on dragon fruit and identify them using molecular biology techniques. The study also investigated the inhibitory effects of silver (Ag) and ZnO nanoparticles on the isolated fungal strains. Methodology and results : Six fungal strains (TL1, TL2, TL3, TL4, TL5, TL6) causing brown spot disease (stem-canker) were isolated. TL1 and TL2 isolates were used for testing the antifungal features of nanoparticles. Nanoparticles were directly added to the PDA medium to make a solution with concentrations of 50, 75 and 100 ppm. The antifungal feature of nanoparticles was screened by inoculating with the fungal samples for 72 h. The inhibitory capacity of ZnO and Ag nanoparticles against fungal strains was then investigated. TL1 and TL2 samples were identified as Neocytalidium dimidiatum using the internal transcribed spacer (ITS) region. The study also revealed that silver nanoparticles were more effective than zinc oxide nanoparticles in inhibiting the growth of fungal strains that cause brown spot disease on dragon fruit. Specifically, ZnO nanoparticles had the highest inhibitory effect on TL2, 61.27% at 100 ppm and Ag nanoparticles gave the highest inhibitory effect on TL2, 85.83% at 100 ppm. Conclusion, significance and impact of study The research findings suggest that the use of Ag and ZnO nanoparticles may be an effective way to control brown dragon fruit spot disease. It may help in improving dragon fruit yield and aesthetic quality. As a result, it may help in reducing economic loss for farmers. However, further research is required.
