ABSTRACT
Background Multi-slice spiral computerized tomography (MSCT) can be used as an auxiliary diagnosis of chest radiography in diagnosis of pneumoconiosis, but there are few studies on the correlations between interstitial images and stage classification of coal workers' pneumoconiosis in the existing literature. Objective To present MSCT imaging manifestations and distribution characteristics of coal workers' pneumoconiosis and complications, evaluate correlations between coal workers' pneumoconiosis stages and pulmonary interstitial lesions, and provide a reliable imaging diagnosis basis for pneumoconiosis interstitial lesions. Methods From June 2022 to June 2023, a total of 1002 patients with coal workers' pneumoconiosis confirmed by the pneumoconiosis diagnostic and identification group in the Department of Occupational Diseases of the Emergency General Hospital were enrolled. MSCT was used to observe the abnormal imaging manifestations of the lungs of coal workers' pneumoconiosis patients and the diseases of pulmonary fibrosis related to their own diseases (thickening of the interlobular septum, bronchial perivascular interstitial mass thickening, parenchymal banding, subpleural line, intralobular interstitial thickening, honeycomb, and subpleural interstitial thickening), the occurrence of coal workers' pneumoconiosis and complications (old tuberculosis, active tuberculosis, pneumonia, atelectasis, lung cancer, bronchiectasis), and the density, size, and location of pneumoconiosis nodules. Imaging data were analyzed and statistically processed. Results All 1002 patients were male, with an average age of (60.71±6.87) years and an average dust exposure time of (23.01±7.80) years. Among them, there were 470 patients with stage I, 422 patients with stage II, and 110 patients with stage III. There were significant differences in the distribution of thickening of the interlobular septum, bronchial perivascular interstitial mass thickening, parenchymal banding, intralobular interstitial thickening, subpleural interstitial thickening, and honeycomb across different stages (P<0.05). Statistically significant differences in p, q, and r subsets of round nodules were found in patients with pneumoconiosis at different stages (P<0.05). Observed nodule types included solid nodules, pure ground-glass shadow nodules, and partial solid nodules. There were statistically significant differences in pulmonary tuberculosis and bronchiectasis among different stages of coal workers' pneumoconiosis (P<0.05). There were statistically significant differences in interstitial shadows and patches combined with interstitial shadows among different stages of pneumoconiosis complicated with pneumonia (P<0.05). Conclusion MSCT provides images of the progression of coal workers' pneumoconiosis and have a certain relationship with the stages of coal workers' pneumoconiosis, which is conducive to the formulation of reasonable treatment plans in the early clinical stage. Therefore, in the diagnosis and treatment of pneumoconiosis, a great attention should be paid to the imaging technology of chest computerized tomography, especially the use of MSCT examination.
ABSTRACT
Objective:To analyze clinical features and imaging characteristics of cryptogenic organizing pneumonia (COP) confirmed by pathological examination, and improve clinicians understanding of the disease and reduce the disease misdiagnosis. Methods:General information, clinical manifestations,laboratory examination and radiographic features of 25 patients with COP confirmed by pathological examination of lung biopsy were collected, and a comprehensive analysis of these data was made. Results:There were 15 males and 10 females in 25 patients.The mean age was (61.4±13.1) years.And 6 cases (24??0%) had smoking history. All patients had no obvious allergic and industrial dust related exposure history. The clinical presentations were nonspecific, and the main clinical symptoms were cough with a small amount of sputum. The most common laboratory tests was counting normal white blood cells and faster blood sedimentation.The main features of chest CT were space occupying lesions and patchy consolidation or ground-glass opacification.Conclusion:The clinical manifestation and laboratory examination of COP lack of characteristic, and the chest CT performance is similar to tumor and lung infection, and the diagnosis of COP depends on pathological examination.In order to reduce misdiagnosis,clinical doctors should improve the awareness and vigilance of the disease.
ABSTRACT
Objective To analyze the clinical and radiographic features of short stature combined with skeletal deformity in children,and to diagnose exactly and cure promptly in children.Methods One hundred and twenty children were collected,included 69 males and 51 females.All of the children were collected detail medical history including history of birth,feeding,growth and development and family history and taken both physical and X ray examination that bone age could be evaluate by Gruelich-Pyle method.The children were taken a laboratory examination including calcium,phosphours,alkaline phosphatase,chromosome karyotype,and so on.Results Among 120 children,there were 36 cases(30.0%) of achondroplasia,20 cases(17.0%)of Turner syndrome,10 cases(8.0%)of multiple epiphyseal dysplasia,1 case(0.8%)of spondyloepiphseal dysplasia congenital,7 cases(5.8%) of spondyloepiphyseal dysplasia tarda,2 cases(1.6%) of osteogenesis imperfecta,1 case(0.8%) of cleidocranial dysplasia,5 cases(4.2%)of mucopolysaccharide Ⅳ,5 cases(4.2%) of pseudoachondroplasia,9 cases(7.5%)of hypophosphatemic ricket,24 cases(20%)of short limb dwarf.Among 120 cases,27 were regularity dwarfism(22.5%),93 cases were irregularity dwarfism(77.5%);Among 93 cases of irregularity dwarfism,80 cases were short limb dwarfism including 36 cases of short upper limb(short upper arm 35 cases,shortforearm 1 case),20 cases of short lower limb,24 cases of proportional short stature,13 cases of short trunk.X ray bone age lag 46 cases,ahead of schedule 15 cases(12.5%),normal 59 cases.Conclusions The main causes of short stature combined with skeletal deformity are genetic bone disease.To analyze the feature of clinical and radiographic is a valuble instrument for the children diagnosis of short stature combined with skeletal deformity.Part of them skeletal age were lagged.
ABSTRACT
PURPOSE: To evaluate the clinical manifestations of contracted joints and the radiological features in mucopolysaccharidosis(MPS). MATERIALS AND METHODS: From January 1996 to March 2002, 15 children from a pool of children diagnosed with MPS through a fibroblast culture and an enzyme assay, who could tolerate a large umber of examinations, underwent orthopedic physical and radiological examinations. RESULTS: There were limitations in the abduction and internal rotation of the shoulder, extension limitation of the wrist, and internal rotation of the hip joint and flexion contractures of the elbow and DIP joints. Scoliotic deformities were all within the physiological curve. There were only three cases of a dorsolumbar kyphotic change and there were no neurological deficits due to the spinal deformities. The mean bone age was delayed compared with the mean chronological age. As the chronological age increased, the gap between the chronological age and the bone age increased. CONCLUSION: Joint contracture, which is the most severe symptom in orthopedic aspect, was more severe in the upper extremities than in the lower extremities. The spinal deformity was relatively mild and there were no neurological problems. The bone age tended to be delayed as the chronological age increased.

Objective:To classify the types of radiographic feature of central salivary gland type malignant tumors of the jaws(CSMTJ) with studying the clinical data,radiographic characteristics and pathological classifications,and to help the diagnose CSMTJ correctly and effectively in future. Methods:The clinical,radiological and pathological features of 62 cases of CSMTJ were studied and summarized. Among these cases,52 cases were collected from the medical records of patients of the internal databank according to the World Health Organization (WHO) Histological Classification of Salivary Gland Tumors standard and 10 cases of CSMTJ were from Guangdong Provincial Stomatological Hospital. Results:The maxilla to mandible ratio was 1∶1.7,Among CSMTJ cases,central mucoepidermoid carcinoma of the jaws (CMCJ) was the most common pathological type and the second was central adenoid cystic carcinoma of the jaws(CACCJ). 62 cases of CSMTJ could be classified into four types:Unicystic type,Multicystic type,"Flame shape" type and Osteolytic type. Conclusion:The radiographic presentation of CSMTJ was very complicated and its classification was connected with tumor malignant degree. The classification was very helpful to determine the treatment methods and the prognosis of the CSMTJ.
