ABSTRACT
@#In September 2020, three pulmonary tuberculosis cases were identified during school physical examinations at a senior high school in a district (School B) of Hangzhou City. Immediate epidemiological surveys were performed by local district and Hangzhou Center for Disease Control and Prevention, and a pulmonary tuberculosis outbreak involving 9 cases in 6 schools were identified. All cases were once Grade 9 students in Class of 2019 at a junior high school (School A), and the source of infection might be a laboratory-confirmed cases (index case) in this class reported in April, 2019. Following exposure to index case, other cases developed disease onset or were screened after entering senior high schools. In November, 2020, tuberculin skin test and chest X-ray scan were performed to screen pulmonary tuberculosis among 43 students and teachers in a class of Grade 9 in Class of 2019 at School A, and 17 students strongly positive for tuberculin skin test were given prophylactic therapy. No pulmonary tuberculosis case were identified until June 2021. It is suggested that early epidemiological surveys facilitates the identification of the epidemiological correlation between cases. Active search for individuals with common exposure history and prophylactic therapy are required if a possible outbreak is found, which is helpful to avoid the spread of the outbreak.
ABSTRACT
Owing to the location of the pancreas and its complex anatomical relationship, it is difficult to perform radioactive Iodine-125 seed implantation in patients with pancreatic cancer as it can cause surgical side effects and further complications. To standardize the procedure of radioactive Iodine-125 seed implantation in the treatment of pancreatic cancer and reduce the occurrence of adverse reactions and complications during and after operation, the Chinese Medical Doctor Association of Radioactive Seed Implantation Technology Expert Committee, Committee of Minimally Invasive Therapy in Oncology, Chinese Anti-Cancer Association, and the Radioactive Seed Therapy Branch organized and helped establish an expert consensus in China regarding radioactive Iodine-125 seed implantation in the treatment of pancreatic cancer. This article aims at interpreting the adverse reactions and complications after the implantation of radioactive seeds.
ABSTRACT
Limited community-based data exist about pulmonary tuberculosis (TB) comorbidity among HIV-infected individuals in China and no data exists about the TB burden in key high risk groups. We recruited 195 known HIV-infected plasma donors in one central China county and identified 9 (4.6%) active TB cases based on clinical assessment, including chest radiography. The low percentage of TB may be explained by improved immunity due to antiretroviral therapy.
