RESUMO
Objective:To understand the characteristics and diagnosis and treatment of brucellosis with joint pain as the first clinical manifestation, and summarize the clinical classification of brucellosis complicated with joint pain, so as to provide reference for clinical diagnosis and treatment.Methods:Cases of brucellosis with first symptom of joint pain diagnosed in the 940th Hospital of PLA Joint Logistic Support Force from January 2015 to January 2020 were selected. The main clinical features, laboratory examination, diagnosis and treatment were analyzed.Results:A total of 82 patients with joint pain of the first symptom were selected, including 61 males and 21 females. Joint pain was the main complaint of the patients, 63.4% (52/82) of the patients visited spine surgery department, 17.1% (14/82) visited minimally invasive orthopedics department, 12.2% (10/82) visited rheumatic immunology department, and 7.3% (6/82) visited traditional Chinese medicine department. Brucellosis patients with cervical lesions accounted for 22.0% (18/82), combined with lumbar lesions accounted for 51.2% (42/82). The patients with elevated C-reactive protein accounted for 68.3% (56/82), abnormal liver function accounted for 52.4% (43/82), anti "O" positive accounted for 3.7% (3/82), abnormal autoantibodies accounted for 6.1% (5/82), and human leukocyte antigen-B27 (HLA-B27) positive accounted for 12.2% (10/82). Four patients with HLA-B27 positive had sacroiliac arthritis. All patients were cured after standard and full course therapy.Conclusion:Joint pain may be the first symptom of brucellosis, and the lumbar spine and cervical spine are the most vulnerable parts.
RESUMO
Objective: To analyze the significance of myocardial enzymes, cardiac troponin T [cTnT] and hepatic and renal function in the treatment of severe pneumonia in children
Methods: One hundred and twenty children with severe pneumonia who were admitted to the hospital between April 2015 and February 2017 were selected and included as a severe pneumonia group; 120 children with common pneumonia were included as a common pneumonia group; 100 healthy children were included as controls. The myocardial enzymes, cTnT and hepatic and renal function of patients in the three groups were detected and compared. The children with severe pneumonia were divided into a mild hypoxia group, a moderate hypoxia group and a severe hypoxia group according to arterial partial pressure of oxygen; the myocardial enzymes, hepatic and renal function and cTnT of the children in the three groups were compared. The correlations of partial pressure of blood oxygen with myocardial enzymes, hepatic and renal function and cTnT were analyzed
Results: The levels of myocardial enzymes, hepatic and renal function and cTnT of the severe pneumonia group, common pneumonia group and control group declined, and the differences had statistical significance [P<0.05]. The levels of myocardial enzymes, hepatic and renal function and cTnT were higher in the children with severe hypoxia. The partial pressure of blood oxygen was in a negative correlation with myocardial enzymes, hepatic and renal function and cTnT in the severe pneumonia group
Conclusion: Timely monitoring of myocardial enzymes, hepatic and renal function and cTnT has an extremely important role in the evaluation of children with severe pneumonia
RESUMO
Objective To evaluate the clinical feature of adult acute myeloid leukemia with nucleophosmin (NPM1) cytoplastic positive (NPMc+AML), and to investigate the significance of the NPM1 gene mutations regularly in detecting the early relapse. Methods The NPM1 gene mutations was screened by the PCR-capillary electrophoresis in 95 newly diagnosed adult AML patients. 5 complete remission AML patients were selected to detecte the NPM1 gene mutations regularly. Results In 95 cases of adult AML patients, the incidence of the NPM1 mutations was 9.5 % (28/95). The incidence of the NPM1 mutations in patients (≥40-year-old) was higher clearly than it' s in pazients (40-year-old) (λ 2= 6.963, P = 0.012). That in the AML patients with normal karyotype (51.1%) was higher than that in the patients with abnormal karyotype (8.3 %) (λ2= 20.860, P= 0.0000). NPM1 mutations occured with a considerate percentage in AML patients with M5/M2 subtype. In AML with recurrent genetic abnormalities the NPM1 mutations wasn' t found.The white blood cell count, platelet count, lactate dehydrogenase in the NPMc+AML patients were clearly higher than that in the NPMc-AML patients (t were individually 4.132, 4.603, 4.069, P ＜0.05). The rate of complete remission, relapse-free survival and overall survival in the NPMc+AML patients were also higher than that in the N PMc-AML patients (λ 2 were individually 10.448, 4.146, 4.384, P ＜0.05). In cases detected regularly NPM1 mutations preceded the hematological relapse about 1.5-2 months. Conclusion NPM1 gene mutations has a higher incidence in adult AML, particularly in normal karyotype AML. The clinical manifestations are older, and higher in white blood cell count, platelet count, and lactate dehydrogenase. The NPM1 mutations in adult AML is a good factor for prognosis. The regular detection of NPM1 mutation could find relapse early.
