A Vietnamese benchmark for vehicle detection and real-time empirical evaluation

The current situation of traffic in Vietnam has many outstanding problems, especially traffic congestion, since the supply of infrastructure has often not been able to keep up with the growth in mobility. Thus, proposing monitoring plans to support authorities to make suitable and prompt decisions has always received large attention from the community. Meanwhile, applying information technology, especially advanced models which could process or analyze traffic data in real time is recently considered to be a priority solution due to the time, accuracy, and cost saving that it can potentially achieve. Therefore, this paper outlines research on three advanced real-time object detection methods: YOLOX, YOLOF, and YOLACT and the development of the newest Vietnamese traffic dataset named UIT-VinaDeveS22. The work contains both theoretical and empirical analysis,  which are expected to create premises for further studies into addressing problems such as traffic density management, traffic separation, and traffic congestion

Efek penambahan ekstrak daun mangga arumanis (Mangifera indica l.) pada antibiotik klindamisin dalam menghambat pertumbuhan bakteri Staphylococcus aureus

Staphylococcus aureus termasuk bakteri yang cukup sering dijumpai pada mulut, terutama pada kasus abses periodontal di mana perawatannya memerlukan pemakaian antibiotik. Tingginya angka resisten bakteri Staphylococcus aureus terhadap antibiotik menyebabkan banyaknya dicari pengobatan alternatif menggunakan herbal. Melihat efek penambahan ekstrak daun mangga arumanis (Mangifera indica L.) pada antibiotik klindamisin dalam menghambat pertumbuhan bakteri Staphylococcus aureus. Jenis dari penelitian ini adalah eksperimental laboratorium secara in vitro dengan 25 sampel. Konsentrasi ekstrak daun mangga yang digunakan 25%, 50%, 75%, 100% dan kelompok kontrol. Ekstrak dibuat dengan teknik maserasi dan uji daya hambat dengan metode Kirbi bauer. Hasil dianalisis menggunakan statistik ANOVA, lalu dilanjutkan dengan Post Hoc LSD. Hasil penelitian ini menunjukkan bahwa penambahan ekstrak 50%, 75%, 100% meningkatkan daya hambat terhadap Staphylococcus aureus (p=0,000) dibandingkan kelompok kontrol. Semakin tinggi konsentrasi yang digunakan, maka semakin besar zona hambat yang terbentuk. Sedangkan penambahan ekstrak 25% tidak meningkatkan daya hambat (p=0,618) bila dibandingkan dengan kelompok kontrol. Penambahan ekstrak daun mangga arumanis dengan klindamisin dapat meningkatkan aktivitas antibakteri terhadap Staphylococcus aureus

The effectiveness of local surgical technique in treatment of axillary bromhidrosis

BACKGROUND: Up to now, surgical excision of apocrine glands still has been a method that yields high treatment results and low rate of odour recurrent for patients, but many people worry about some serious complications that have been observed postoperatively, such as hematoma and skin necrosis. These prolong wound healing, leading to unsightly scars in the axillary fossae. AIM: We conducted this research to investigate the effects and complications of our surgical technique for axillary bromhidrosis. METHODS: Forty-three patients with axillary bromhidrosis were treated. An elliptical incision was made at a central portion of the area marked, with both tips of the ellipse along the axillary crease. The elliptical skin with the subcutaneous tissue was removed en lock. The adjacent skin was undermined to the periphery of the hair-bearing area with straight scissors. The undermined subcutaneous tissue was removed with curved scissors, and the skin was defatted to become a full-thickness skin flap. Any suspected hemorrhagic spots were immediately coagulated electrosurgically. Appropriate drains were placed, and the treated area was covered with thick gauze to each axilla. Arm movement was strictly controlled in the first 3 days post-operatively. RESULTS: Thirty-one patients have been followed up and evaluated for 6 months. 56 out of 62 axillae (90.3%) showed good to excellent results for malodor elimination. All patients reported a reduction in axillary sweating. There were two axillae of skin necrosis and three axillae of hematoma, with one patient receiving an anticoagulant from a cardiologist after the first day of surgery, to treat heart valve disease. The Dermatology Life Quality Index (DLQI) score decreased significantly, and the quality of life improved after the operation. CONCLUSION: Our technique is a simple surgical procedure and easy to perform helping to achieve results for high malodor elimination, with almost no serious complications. Patient’s life quality improved significantly after the operation

Efficacy of Oral Isotretinoin in Combination with Desloratadine in the Treatment of Common Vulgaris Acne in Vietnamese Patients

AIM: To evaluate the efficacy of oral isotretinoin used alone and in combination with desloratadine in the treatment of moderate acne vulgaris. METHODS: A comparative clinical trial was undertaken to evaluate the efficacy of oral isotretinoin alone and in combination with desloratadine in the treatment of 62 moderate acne vulgaris patients. Patients were randomised into two groups with 31 patients in each group. Each studied group's patient took 20 mg isotretinoin and 5 mg desloratadine per day. In the control group, patients took only 20 mg isotretinoin per day. The treatment time was 16 weeks. The evaluation and follow-up were done at week 2, 4, 8, 12 and 16 of the treatment. RESULTS: The studied group had a better curative rate than the control group (45.2% versus 22.6%). The average number of inflammatory lesions in the studied group was significantly lower than the control group (0.19 versus 0.94). The mean GAGS score of the studied group was significantly lower than the control group (3.71 versus 6.52). Acne outbreaks rate of the studied group was lower than the control group (in week 2: 22.6% versus 45.2% and in week 4: 16.1% versus 38.7%, respectively). The rate of itchy was lower in the studied group. CONCLUSION: In the treatment of moderate acne vulgaris, oral isotretinoin in combination with desloratadine is more effective and has fewer side effects than using isotretinoin alone

The Effectiveness of Oral Mini-Pulse Methylprednisolonein - the Treatment of Alopecia Areata in Vietnam

BACKGROUND: Systemic corticosteroid is used to treat alopecia areata, but it is associated with side effects. Mini-pulse therapy is thought to be effective but able to reduce side effects. AIM: The study aimed to evaluate the effectiveness of oral mini-pulse methylprednisolone in the treatment of alopecia areata. METHODS: Patients received methylprednisolone 16 mg orally for 2 consecutive days every week. RESULTS: After 3 months, among patients, 40% recovered well, and 55.6% recovered fairly. After 6 months, 82.2% recovered well, 17.8% recovered fairly. No adverse events were detected, and the recurrence rate was low (2.2%). CONCLUSION: Oral mini-pulse methylprednisolone therapy is an effective and safe therapeutic option for alopecia areata without side effects, and the time of the treatment is short
