Key Clinical Message Gallbladder volvulus (GV) is a medical emergency and a rare cause of acute abdominal pain among the pediatric population. GV is more prominent usually in boys in pediatric patients. If it is not diagnosed and surgically intervened promptly, GV will become a life‐threating condition. Fortunately, a safe and effective laparoscopic cholecystectomy is now widely indicated. A 5 years old female patient with abdominal pain and heavy much vomiting was referred to the emergency room in our hospital. She was suspiciously diagnosed with acute inflammation of the gallbladder according to the results of abdominal ultrasound and computerized tomography (CT) scan already performed on admission. One day after the hospitalization, abdominal ultrasound, and CT scan were performed again because of intensification of her abdominal pain and revealed the clinical portrait of GV such as a “floating gallbladder” sign, an echogenic cone structure, an elongated axis displaced horizontally instead of vertically and a lack of intramural blood flow. The acute GV diagnosis was made and the patient was operated, using the laparoscopic cholecystectomy on time, the gallbladder was tightly twisted clockwise at approximately 720°. The operation and postoperative treatment went quite well and the patient was discharged from the hospital on postoperative Day 7. GV is very rare in children, easily omitted or misdiagnosed with cholecystitis. Imaging diagnosis such as ultrasound, CT with contrast helps make diagnosis promptly that avoids severe complications such as gallbladder perforation, necrosis, and biliary peritonitis.

Objective: This study aims to evaluate the safety and immunogenicity of the SKYVaricella vaccine in healthy Vietnamese children aged 12 months to 12 years. Methods: This open-label, single-arm study involved 201 children divided into two groups: 60 children aged 12 months to 5 years and 141 children aged 6 to 12 years. Safety was assessed through immediate reactions, solicited adverse events within 7 days, and unsolicited events up to Day 42. Immunogenicity was evaluated by seroconversion rates (SCR) and geometric mean titer (GMT) increments using fluorescent antibody-to-membrane antigen (FAMA) on the day of vaccination (D0) and 42 days after vaccination (D42). Results: All participants completed the follow-up. Immediate adverse events included pain (8.0%), redness (8.0%), and swelling (20.9%) at the injection site. Within 7 days, pain (17.9%) and swelling (12.4%) were mild and self-resolving. Unsolicited adverse events were infrequent and mild. Both age groups achieved 100% SCR. GMT of varicella-zoster virus antibodies increased from 1.37 (SD 1.97) at D0 to 18.02 (SD 2.22) at D42, a 13.12-fold rise. No Grade 3 adverse events were observed. Conclusion: The SKYVaricella vaccine shows a robust immunogenic response and favorable safety profile in Vietnamese children aged 12 months to 12 years. These findings endorse its potential inclusion in pediatric vaccination programs as a reliable preventive option against varicella.

Abstract Background In high-risk patients with complex pulmonary aspergilloma but unable for lung resection, cavernostomy and thoracoplasty could be performed. This study aimed to evaluate this surgery compared two compressing materials. Methods A total of 63 in high-risk patients who suffered from hemoptysis due to complex pulmonary aspergilloma and underwent cavernostomy and thoracoplasty surgery from November 2011 to September 2018 at Pham Ngoc Thach hospital were evaluated prospectively studied. Patients were allocated to two groups: the table tennis ball group and tissue expander group. We evaluated at the time of before operation, 6 months and 24 months after operation. Results Tuberculosis was the most common comorbidity diseases in both groups. Upper lobe occupied almost in location. Hemoptysis symptoms plunged from time to time. Statistically significant Karnofsky score was observed in both groups. Postoperative pulmonary functions (FVC and FEV1) have remained in both groups at all time points. The remarkable results were no deaths related to surgery and low complications both short and long-term. There was no statistical significance between two groups in operative time, blood loss during operation, ICU length-stay time. Four patients died because of co-morbidity in 24 months follow-up. Conclusion Cavernostomy and thoracoplasty was safe and effective surgery for the treatment of complex pulmonary aspergilloma with hemoptysis in high-risk patients. No mortality related to surgery and low complications were recorded. The was no inferiority when compared two compressing materials .

Smoking is a global health problem among health science students. The objectives of this study were to estimate the prevalence of smoking and to examine associated factors among health science students from five universities in Vietnam. Among 5946 participants (95.0% response rate), the smoking prevalence was 19.2% (95% CI:17.4–21.0%) among male students and 2.9% (95% CI:2.4–3.5%) among female students. In the multivariable regression models, significant factors for smoking were the perceived financial burden, the respondent’s year in university, a non-self-determined motivation profile, self-reported depression and/or anxiety, the level of vigorous physical activity, and alcohol drinking.

Evaluation of the outcome of the miniaturized percutaneous nephrolithotomy in the treatment of nephrolithiasis with a lateral position based on the principle of a right triangle under the guidance of a C-Arm without contrast fluid. Materials and Methods: Sixty-nine cases of Mini-PCNL with the assistance of a vacuum-assisted sheath in the lateral position were performed at Central Hospital from March 2021 to August 2022. Percutaneous renal access was under the guidance of a non-rotational C-arm without contrast medium, and we determined the puncture location and depth of the needle based on the principle of right triangles. Results: The median age was 51.6 ± 12.5 years, and males accounted for 68.1% of the cases. 60.9% of all patients had normal weight. The median stone surface area was 361.1mm2, and 59.4% of all cases were graded as 2 regarding Guy's stone score. The successful renal access rate was 100%. The tunnel access from the middle and lower calyx accounted for 94.2%. The median access duration, fluoroscopy duration, and hospital length of stay were 271.7 seconds, 14.79 seconds, and 6.3 days, respectively. The complete stone clearance rate was 78.3%. Bleeding complications occurred in 2 patients without mortality. Three patients required an additional procedure. Conclusion: The puncture technique into the renal calyxes based on the principle of the right triangle under the guidance of a non-rotational C-Arm without contrast medium in PCNL is a fast, exact, and safe technique.
