Objective To investigate the reasons, status, treatment and precautions of misdiagnosis of pulmonary inflammatory pseudotumor. Methods Between January 2005 and December 2015, one hundred eighteen articles about pulmonary inflammatory pseudotumor published in Wanfang and CNKI databases were retrospectively analyzed, among them forty-four articles referring to misdiagnosis rate. The misdiagnosis rate, distribute of misdiagnosed diseases, reasons and main means of definite diagnosis were analyzed. Results There were 1 286 cases of pulmonary inflammatory pseudotumor in the 44 articles, of them 1 012 cases were misdiagnosed. The misdiagnosis rate was 78.84%. Pulmonary inflammatory pseudotumor was often misdiagnosed as lung cancer (65.81%), tuberculosis (15.42%, which included 72 cases of tuberculoma and accounted for 7.11%) and benign pulmonary neoplasms (9.59%). Most misdiagnosed patients did not suffer from adverse consequences, except a few patients undergo unnecessary extended operations. Lack of specificity in clinical manifestations, lack of awareness about the disease, dependent on auxiliary examination and lack of awareness about the fine feature of the disease were the main reasons of misdiagnosis. The majority of misdiagnosed cases were terminal pathological diagnosed through the operation or after percutaneous biopsy. Conclusions Pulmonary inflammatory pseudotumor is lack of specificity in clinical manifestations and easy to be misdiagnosed. It is very important to analyze and identify the fine feature of imaging changes. To reduce and avoid misdiagnosis, clinicians should improve the awareness of this disease.
Objective To investigate the control level in asthmatic patients who were members of asthma association in the People’s Hospital of Peking university.Methods 76 asthmatic patients attended the Third Meeting of asthma association and asthma test was conducted.The patients self-evaluated the state of illness，filled the questionnaire of asthma control test（ACT） while peak expiratory flow（PEF） was measured.The steroids usage was also investigated.Results The average age of the patient investigated was（60.6±11.5）year old.The percentage of well control by self-evaluation was 89.5%（62/76）；75%（48/64） by ACT questionairs.50.8%（31/61）of the patients fell in green region and 36.1%（22/61）fell in yellow region of PEF.The coincidence rate of self-evaluation with ACT was 40.6%.ACT scores comparable to green region，yellow region and red region were 21.33±3.44，21.12±3.24 and 17.43±4.47 respectively.There were no significant difference of ACT score between green region group and yellow region group，or yellow region group and red region group.Conclusions Most of asthma association members could achieved well control which could be ascribed to asthma education and management program on the basis of partner relationship between doctors and patients.
ObjectiveTo explored the influence of disease changes, weight gain, eosinophil levels and other factor in pregnancy women with asthma. MethodsCase records of gestational asthma patients produced in the obstetrics department of Peking University People's Hospital from October 2010 to October 2020 were collected, and refer to electronic medical records of clinics (pre-pregnancy and pregnancy). According to the disease control (asthma related unplanned respiratory clinics, emergency or hospitalization), patients were divided into pregnancy stable group and pregnancy fluctuation group. The basic characteristics, pre-pregnancy asthma control, weight gain during pregnancy and peripheral blood eosinophil level before labor were retrospectively analyzed. The cause of asthma attacks, clinical characteristics and distribution of gestational time in pregnancy fluctuations were described. Peripheral blood eosinophil levels in different period during pregnancy in the stable group were analyzed. ResultsTotally 124 cases of natural pregnancy singleton were enrolled in the study. The age was (32.3±3.9) years old. There were 71 patients in stable group and 53 patients in fluctuation group. The proportion of pre-pregnancy instability in the fluctuating pregnancy group was higher than that in the stable pregnancy group (P<0.05). The proportion of intermittent medication before pregnancy was higher in the fluctuating pregnancy group than in the stable pregnancy group (P<0.05). Peripheral blood eosinophil count before labor and the number of cases with eosinophil count≥0.15×109/L before labor were higher in the fluctuation group (all P<0.05). The proportion of hypertentive diseases in pregnancy and fetal distress in uterus were higher in the fluctuation group (all P<0.05). The common cold was the common trigger factor (38.2%) and asthma recurrences occur between 13 and 36 weeks of gestation (65.8%) in fluctuation group. In further analysis of subgroup (the stable group), peripheral blood eosinophil count in early pregnancy (P<0.05) and pregnant metaphase (P<0.05) were higher than before delivery. The number of cases with eosinophil count>0.15×109/L in pregnant metaphase (P<0.05) was higher than before delivery. ConclusionsAsthma fluctuates during pregnancy is associated with adverse maternal and fetal outcomes. It is very important and critical that asthma control before pregnancy, weight gain management and eosinophil level monitoring of patients with asthma during pregnancy. The whole management is imperative in women with asthma during pregnancy.
