Objective To analyze the clinical presentations and radiological characteristics of acute exacerbation of idiopathic pulmonary fibrosis ( IPF) . Methods Clinical and radiological data of 2 patients with acute exacerbation of IPF from April 2006 to July 2008 were retrospectively analyzed and literatures were reviewed. Results Both patients were senior male patients over 60 years old. Dyspnea, cough and inspiratory crackles were the major symptoms and signs. Two patients were experiencing an exacerbation of dyspnea for one week and half of month, respectively. PaO2 /FiO2 of both patients was less than225 mm Hg. In both patients, high-resolution computed tomography ( HRCT) scans at the exacerbation showed typical signs of IPF including peripheral predominant, basal predominant reticular abnormality, with honeycombing and traction bronchiectasis and bronchiolectasis, and newly developing alveolar opacity. HRCT scan showed peripheral area of ground-glass attenuation adjacent to subpleural honeycombing in one patient, and diffusely distributed ground-glass opacity in another patient. Two patients had received corticosteroid treatment. For one patient, the symptoms improved, and ground-glass attenuation adjacent to subpleural honeycombing had almostly resolved. The other patient died of respiratory failure. Conclusions Some acute exacerbation in idiopatic pulmonary fibrosis can be idiopathic. The clinical presentations mainly include the worsening of dyspnea within short time. HRCT generally demonstrates new bilateral ground-glass abnormality with or without areas of consolidation, superimposed on typical changes of IPF.
Objective To investigate the mental status of medical staffs in the orthopedics department during the earthquake, providing evidence for psychological intervention. Methods Choosing 104 staffs in the orthopedics department as eligible subject with convenient sampling; the research tool was Symptom Checklist-90. The questionnaire was done by the participants with the same instruction from psychological professionals; analyze the results. Results The score in somatization, anxiety and phobic anxiety of staffs in the orthopedics department was significantly higher than the national norm. Conclusion There exists disorder in mental health of medical staffs in orthopedics department, it is necessary to implement mental intervention.
Objective To investigate the differences in clinical characteristics and polysomnographic characteristics between the elderly obstructive sleep apnea-hypopnea syndrome ( OSAHS) patients and the young and middle-aged OSAHS patients. Methods The clinical manifestations and the polysomnographic characteristics of 37 elderly OSAHS patients and 294 young and middle-aged patients were analyzed. The differences in polysomnographic indicators between two groups were compared according to the body mass index.Results The nocturia frequency in the elderly OSAHS patients was higher( P =0. 01) ,however, the othert clinical manifestations between the elderly group and the young and middle-aged group were not different significantly. The elderly group had a lower body mass index ( P =0. 018) , a smaller neck circumference ( P =0. 003) , and a larger chance of diabetes ( P = 0. 001) and hypertension( P lt; 0. 001) .The phase Ⅰ and phase Ⅱ sleep of the elderly group took a longer duration ( P lt; 0. 001) and a larger proportion( P lt;0. 001) . The sleep apnea-hypopnea index between two groups did not show any significant difference( P =0. 082) . The lowest night oxyhemoglobin saturation of the elderly group was higher than that of the young and middle-aged group( P =0. 009) , but such difference disappeared after adjustment by weight ( P =0. 114) . Conclusions The major clinical manifestations of the elderly OSAHS patients are similar to the young and middle-aged patients. The elderly patients are thinner than the young and middle-aged patients, but have more complications and a higher frequency of nocturia. The night oxyhemoglobin saturation is lower in young and middle-aged patients which is associated with higher body mass index.
ObjectiveTo investigate Chinese psychiatrists' mental health. MethodsLiteratures published from January 1989 to March 31, 2013 were searched through Chinese network databases (CNKI, Weipu, Wanfang) and English network database (OVID). Factors of Symptom checklist-90 (SCL-90) were extracted and compared with Chinese norm. These were analyzed by Meta analysis method. ResultsEleven articles were obtained and analyzed, including 725 psychiatrists. The research illustrated that the differences between psychiatrists and Chinese norm of somatization[WMD=0.19, 95%CI (0.05, 0.33), P=0.008], depression[WMD=0.25, 95%CI (0.06, 0.43), P=0.009], anxiety[WMD=0.28, 95%CI (0.09, 0.47), P=0.004], hostility[WMD=0.15, 95%CI (0.01, 0.30), P=0.03], and phobia[WMD=0.11, 95%CI (0.02, 0.20), P=0.02] were significant, while the other 4 factors were not significant (P>0.05). ConclusionPsychiatrists' mental health is poor and intervention measures need to be adopted to improve psychiatrists' mental health.
Objective?To explore the clinical and imaging features of cranial venous sinus thrombosis (CVST). MethodsThe clinical data of 20 patients with CVST treated between January 2008 and December 2012 were retrospectively analyzed, including the clinical manifestations, neuroimaging characters and treatment outcomes. ResultsAmong the 20 patients, there were 10 infected cases; D-dimer was detected positively in only 2 cases; cerebrospinal fluid pressure increased in 13 patients; and red blood cell population of cerebrospinal fluid increased in 12 patients. The common clinical symptoms included headache in 16 cases, eye symptoms in 12 cases, and vomiting in 10 cases. CT showed the direct signs of CVST in 3 cases, and MRI showed the direct signs of CVST in 6 cases. The common disease regions were in left transverse sinus and sigmoid sinus in 5 cases, superior sagittal sinus in 5 cases, and multiple venous sinus in 5 cases. Eighteen patients only received anticoagulation, and 2 received anticoagulation and local thrombolytic treatment. Fourteen cases recovered fully, 6 had dysfunctions. ConclusionThe clinical manifestations of CVST are nonspecific. This disorder predominantly affects childbearing women. Infection is a common cause of CVST. The occlusive venous sinus can be confirmed by enhanced magnetic resonance venography or digital subtraction angiography. Anticoagulation and local thrombolytic therapy are both proved to be safe and effective in the treatment of CVST. The early diagnosis rate of CVST remains to be improved.
ObjectiveTo explore the correlation of respiratory diseases in respiratory clinic with air quality and temperature in winter. MethodsThe data of patients in the respiratory clinic in Anyang District Hospital were collected from November 1, 2012 to February 28, 2013. The air quality and weather condition were investigated in the local environmental protection department and meteorological department simultaneously. The number of outpatients,prevalence of main symptoms and main respiratory diseases as preliminary diagnoses were recorded. Their relations with air pollution index (API) and air temperature were analyzed. ResultsPearson correlation coefficient of daily API with the outpatients number of the day,the next 1 day and the next 3 days were 0.725, 0.331 and 0.257, respectively (P<0.01), which indicating a positive correlation. The average number of outpatients per day increased by 21.4%, 42.6% and 50.4%, respectively with increased API scale, so did the prevalence of main symptoms and that of main respiratory diseases as preliminary diagnoses. Pearson correlation coefficient of API with cough with sputum, and asthma were 0.287 and 0.277, respectively (P<0.01), which indicating a positive correlation. Pearson correlation coefficient of API with upper respiratory infection, bronchitis, bronchial asthma, and pneumonia were 0.184, 0.251, 0.301 and 0.227, respectively (P<0.05), which indicating a positive correlation. The average number of outpatients was stable when temperature ranged from -3℃to 15℃,increased by 34.5% when temperature ranged from -4℃to -3℃,and increased by 9.3% more when temperature ranged from -5℃to -4℃. Cough was more sensitive to air temperature, and the prevalence of cough increased by 35.7% when temperature ranged from -4℃to -3℃,and increased by 14.0% more when temperature ranged from -5℃to -4℃. Pearson correlation coefficient of air temperature with sinusitis, bronchial asthma, and sputum were -0.194, -0.383 and -0.191, respectively (P<0.05), which indicating a negative correlation. ConclusionsIn winter,the number of outpatients increases with the increase of API. Respiratory diseases and symptoms are closely related to air quality and temperature.
ObjectiveTo observe and analyze the fundus of pregnancy-induced hypertension syndrome (PIHS) and optical coherence tomography (OCT) characteristics and its correlation with ocular symptoms and degree of the systemic disease. MethodsA total of 132 PIHS patients (264 eyes) received the examinations of corrected visual acuity, slit lamp microscope, direct ophthalmoscope, OCT and fundus color photography after obtaining informed consent in the study. There were 10 cases of gestational hypertension, 29 cases of preeclampsia (mild), 82 cases of pre-eclampsia (severe) and 11 cases of eclampsia. 91 patients (180 eyes) felt blurred vision and visual fatigue. 102 patients were examined at an average gestational age of (37.00±2.14) weeks and 30 patients were examined at an average (10.00±8.22) days postpartum. The ocular fundus was divided into normal fundus and abnormal fundus; the abnormal fundus had 3 stages, including stageⅠ(retinal arterial spasm), stageⅡ(retinal arteriosclerosis) and stageⅢ(retinopathy). If the OCT results seems to be abnormal, these patients were further selected to observe the changes of neurosensory serous retinal detachment, retinal pigment epithelium (RPE) and junction of inner and outer segment of photoreceptor (IS/OS). Kappa test was used to analyze the consistency between fundus performance and OCT results, and that of ocular symptoms with fundus changes and OCT results. Rank correlation test was used to analyze the degree of PIHS and OCT examinations. ResultsThere were 32 eyes with normal fundus (12.12%) and 232 eyes with abnormal fundus (87.88%). The 232 eyes with abnormal fundus were divided into three stages: stageⅠfor 16 eyes (6.90%), stageⅡfor 31 eyes (13.36%) and stageⅢfor 185 eyes (79.74%). 92 of 264 eyes (34.85%) had normal OCT findings, 172 eyes (65.15%) were abnormal, including 94 eyes with serous retinal neurosensory detachment (54.65%), 40 eyes with changes of RPE and IS/OS (23.26%) and 38 eyes with other manifestations (22.09%). Kappa test analysis showed highly consistency between OCT results and ocular symptoms (K=0.728, Po=0.591), and poor consistency between fundus abnormalities and ocular symptoms (K=-0.129, Po=0.879), and between fundus abnormalities and OCT results (K=0.174, Po=0.682). OCT results were positively correlated with the degree of PIHS (C=0.374, χ2=74.011; P=0.000). Conclusions87.88% of PIHS eyes had various degrees of retinal hemorrhage, cotton wool spots, retinal bumps or detachment, optic disc edema and other retinal abnormalities. 65.15% of that showed OCT abnormal results such as neurosensory retinal detachment, cystoid edema, RPE changes etc. The consistency was poor between the OCT results and fundus abnormalities. OCT results are positively correlated with the degree of PIHS.
ObjectiveTo summarize the clinical features and imaging features of CT in the omental torsion, and in order to reduce the misdiagnosis and missed diagnosis rate of imaging features. MethodsThe data of 16 cases of omental torsion (secondary 15 cases, primary 1 case) and 286 cases of acute appendicitis (eliminated the subhepatic and retroperitoneal ectopic appendix) in our hospital from 1998 to 2014 were retrospectively analyzed. ResultsEleven cases of omental torsion suffered from the shifting pain in right lower quadrant. No obvious shifting abdominal pain was observed in other 4 cases whose main manifestations were abdominal tenderness and rebound tenderness around umbilicus. The patient of the remaining 1 case had enclosed mass in the area of left groin with pain and suffered from continuous periumbilical pain. Abdominal spiral CT examination was performed in 16 patients before operation. Increased signal intensity of globular soft tissue, which deviating from McBurney's point, was found at level of distal umbilicus by preoperative spiral CT in 13 cases. One case of omental torsion associated with ncarcerated inguinal hernia was missed. ConclusionsOmental torsion manifests chiefly shifting pain in right lower quadrant, abdominal tenderness, and rebound tenderness around umbilicus. It is easily confused with appendicitis. Abdominal spiral CT should be chosen as a preferred means in preoperative diagnosis of omental torsion.
Objective To explore the mental health status and the relevant influencing factors of the resident standardized trainees, and to provide reference for the psychological intervention. Methods All the resident standardized trainees in a first class of the third grade hospital in Sichuan from July 2012 to August 2015 were investigated by the questionnaire including symptom checklist 90, demographic characteristics and work condition. Results The detection rate of psychological problem among resident standardized trainees was 24.7% which was higher than the general population. The analysis of logistic regression showed that the training grade, identity, work time and working achievement were the main factors related to psychological problems. Conclusions The psychological problems of resident standardized trainees were prominent because they are in a transformation stage from medical students to clinical doctors. The related department should pay more attention and take measures to improve the resident standardized trainees’ mental health.
Objective To explore the clinical characteristics of patients with lymphoma firstly manifested as symptoms in respiratory system. Methods The clinical data of 9 patients with lymphoma were analyzed retrospectively and discussed with literature review. Results There were 7 males and 2 females with an average age of 48.2 years and a median disease course of 20 days. All patients were diagnosed by pathology while specimens were obtained by cervical lymph node biopsies in 2 cases, by CT-guided percutaneous lung biopsies in 2 cases, by bronchoscope mucosal biopsies in 2 cases, by transbronchial needle aspiration biopsies in 1 case, by thoracoscope lung biopsies in 1 case, and by ascites cell block inspection in 1 case. The main symptoms were cough (7/9), expectoration (3/9), fever (3/9) and wheeze (2/9). Chest CT showed tumors (3/9, multiple in 1 case), enlarged mediastinal lymph nodes (6/9), enlarged hilar lymph nodes (3/9), pulmonary consolidation (3/9), pleural effusion (6/9, bilateral in 3 cases), pleural thickening (2/9), pulmonary atelectasis (2/9), patchy shadow (7/9), pericardial effusion (1/9). Laboratory examination demonstrated elevated cancer antigen 125 (CA125) in 7 cases while elevated lactic acid dehydrogenase (LDH) in 4 cases. One patient died during hospitalization in the respiratory department, 1 patient auto-discharged without further treatment, 1 patient died in follow-up period. Five patients remain alive up to now. Conclusions The symptoms of patients with lymphoma are atypical while the chest radiological findings are varied. CA125 and LDH play important role in evaluating disease and predicting prognosis in patients with lymphoma.
