Among current treatment options, Allergen Immunotherapy (AIT) is the only method capable of modifying the natural course of allergic diseases, including asthma.</span> </p> <p><span class="fontstyle0"> AIT works by introducing gradually increasing doses of speci„c allergens into the patient’s body, thereby helping to restore immune tolerance and reduce IgE-mediated allergic inƒammation. There are two common routes of AIT administration: subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT). Numerous clinical trials and systematic reviews have demonstrated that AIT is e ective in alleviating respiratory symptoms, improving lung function, reducing the need for controller medications, and preventing severe disease progression. Moreover, the bene„ts of AIT can persist for years after completing the treatment course.</span></p> <p><span class="fontstyle0">AIT plays a particularly important role in the management of mild to moderate persistent allergic asthma that is inadequately controlled with standard medications, especially in patients with documented sensitization to speci„c allergens (e.g., house dust mites, pollens). The selection of allergens, assessment of indications and contraindications, and close monitoring throughout the treatment process are critical factors determining the success of AIT. Nowadays, AIT is gaining increasing attention as part of personalized asthma treatment strategies, especially when combined with biologic therapies, aiming to optimize treatment outcomes and improve patients’ quality of life.</span></p> 2025-08-22T00:00:00+00:00 Copyright (c) 2025 https://tcnhikhoa.vn/index.php/tcnk/article/view/412 OVERVIEW OF THE SITUATION OF MYOPIATIC STUDENTS IN THE VIETNAM’S SCHOOL ENVIRONMENT NOWADAYS, SOME RESEARCH ISSUES NEED TO BE DISCUSSED AND PROPOSE SOME SOLUTIONS 2025-08-20T17:24:46+00:00 Anh Hao Bui buianhhao1309@gmail.com <p><span class="fontstyle0">Myopia is the most common type of refractive error in Vietnamese students nowadays, especially this type of refractive error can be seen most clearly in the school environment, with the number of students with myopia increasing over time, every year the current situation is very staggering, aecting student’s health, education quality and their future. The current situation of myopia in students in Vietnam’s school environment poses many research challenges for doctors, when necessary, may require timely medical interventions to control and reduce the rate of myopia in students, in addition to bringing up some discussions about educating and preventing myopia from an early age for students, avoid the harmful consequences in the future, and propose some solutions to help reduce myopia in Vietnamese students nowadays.</span> </p> 2025-08-22T00:00:00+00:00 Copyright (c) 2025 https://tcnhikhoa.vn/index.php/tcnk/article/view/413 EVALUATION OF HUMORAL IMMUNITY IN CHILDREN WITH RECURRENT RESPIRATOTY TRACT INFECTIONS AT THE PEDIATRICS DEPARTMENT OF VINMEC TIMECITY INTERNATIONAL GERENAL HOSPITAL 2025-08-20T17:29:48+00:00 Thị Minh Hương Le leminhhuongnew@gmail.com Khac Tiep Pham tapchinhikhoa@gmail.com Thi Thao Do tapchinhikhoa@gmail.com Thi Kim Oanh Bui tapchinhikhoa@gmail.com Lan Huong Pham tapchinhikhoa@gmail.com <p><span class="fontstyle0">Evaluation of humoral immunity in children with recurrent respiratoty tract infections focuses on the role of immunoglobulin antibadies, helpng to determine the child’s immune responese capability while simultaneously excluding underlying immunodeciency disorders.</span> </p> <p><span class="fontstyle0"><strong>Method:</strong> </span><span class="fontstyle2">A cross-sectional descriptive study of 207 cases, aged 6 months to 8 years, diagnosed with recurrent respiratory tract infections. The study indicators included medical history, respiratory in‡ammation inđẽ according to the ICD 10, frequency of infections, and measurement of antibody levels (IgA, IgG, IgM, IgE). The antibody levels were compared with reference values by age group.</span> </p> <p><span class="fontstyle2"> <span class="fontstyle0"><strong>Results:</strong> </span>The average age of the study patients was 2.48 ± 1.46 years, with the majority being children under 3 years old (accounting for 69.6%). The percentage of boys is 63,6%. The most frequently encounted conditions, in order, are acute pharyngitis (100%), bronchitis (66,7%), otitis media (53,6%) and pneumonia (45,9%). IgA concentration was reduced in 7,7% children in the study. The younger the child, the higher rate of IgA reduction (14.5% in the 6-12 month age group, 7.1% in the 2-3 year age group). The frequency of lower respiratory tract infections was signicantly higher in the 2-3 year age group with decreased IgA levels (p=0.007). 2.4% of children had decreased IgG levels, mainly concentrated in the under 1 year old group, accounting for 7%. In addition, 23.1% of children had elevated IgE levels regardless of age. <br></span></p> <p><span class="fontstyle2"><strong> <span class="fontstyle0">Conclusion: </span></strong>Recurrent respiratory tract infections are more common in young children under 3 years old. 7.7% of children with recurrent respiratory tract infections had reduced IgA and 2.4% had decreased IgG compared to the reference values by age. There is a relationship between decreased IgA levels and the frequency of lower respiratory tract infections in the 2-3 years old group.<br></span></p> <p>&nbsp;</p> 2025-08-22T00:00:00+00:00 Copyright (c) 2025 https://tcnhikhoa.vn/index.php/tcnk/article/view/414 ASSESSMENT OF BASIC PEDIATRIC EMERGENCY COMPENTENCIES AMONG HEALTHCARE PROVIDERS IN LAO CAI PROVINCE IN 2024 2025-08-20T17:39:31+00:00 Minh Dien Tran tapchinhikhoa@gmail.com Huu Phuc Phan tapchinhikhoa@gmail.com Ngoc Duy Le duy2411@yahoo.com Thi Oanh Nguyen tapchinhikhoa@gmail.com Van Thang Nguyen tapchinhikhoa@gmail.com Thi Hoa Quach tapchinhikhoa@gmail.com Hoai Bac Tran tapchinhikhoa@gmail.com Hoang Kien Tran tapchinhikhoa@gmail.com Thai Hiep Duong tapchinhikhoa@gmail.com <p><strong><span class="fontstyle0">Objectives: </span></strong><span class="fontstyle2">To evaluate the basic pediatric emergency competencies of physicians and nurses in provincial and district hospitals in Lao Cai Province, aiming to propose appropriate intervention and training strategies.</span></p> <p><span class="fontstyle0"><strong>Subjects and Methods:</strong> </span><span class="fontstyle2">A cross-sectional study conducted from January to March <span class="fontstyle0">2024.

Most SVT in the neonate is due to a re-entrant mechanism. SVT may initially be asymptomatic, but when prolonged it may result in congestive cardiac failure and shock after a variable period. The efective treatment of any arrhythmia requires attention to overall hemodynamic status and the mechanism of arrhythmia. The present study reports three cases of neonatal patients were referred to our department with tachycardia and hemodynamic instability. Although there are still many limitations in treatment (the frst-line drug as Adenosine, ...), but we have successfully treated it with available resources at the our hospital. In this report, the authors present the clinical, paraclinical and outcomes features of neonatal arrhythmias with review of the literature.</p> 2025-08-22T00:00:00+00:00 Copyright (c) 2025
