Objective To investigate the clinical features, diagnosis, and treatment of patients with localized epithelioid sarcoma (ES).Methods From January 2000 to September 2006, 11 patients with ES weretreated. There were 7 males and 4 females aged 14-41 years. The patients’ agesat the initial onset were 9-41 years, averaged 27.7 years. The ES was located in the upper extremity in 7 patients，lower extremity in 3, and abdomen in 1. Among the patients, 10 had a recurrence. Tumor lt; 2cm was seen in 7 patients, 2-5cm in 1, and gt;5 cm in 3. One patient underwent an operation of local resection at another hospital. Seven patients underwent an expanding resection surgery, and the tumors with the surrounding normal tissues 3 cm above were removed. Three patients underwent a radical surgery, including extremity amputation or finger amputation. All the patients underwent routine radiotherapy and chemotherapy after operation. Results All the wounds had a healing at the firstintention without complications. All the flaps survived and the grafted bone had a fusion. Among the 11 patients followed up for 5-54 months averaged 23.2 months, 8 had a recurrence 2-20 months (average, 8.9 months) after operation, witha recurrence rate of 73%. And among the patients, 3 had a further radical surgery of extremity amputation. Four patients had a metastasis in the axillary lymphnodes 6-24 months after operation, and 1 patient had a lung metastasis 10 months after operation. They did not have a further surgical treatment. Four patients died of systemic failure 6-14 months after operation. Conclusion An early expanding resection surgery combined with postoperative chemotherapy and radiotherapy is the therapy of choice for treating ES.
ObjectiveTo improve the knowledge of pulmonary actinomycosis.MethodsThree cases of pulmonary actinomycosis in this hospital and 65 cases reported in China were analyzed retrospectively.ResultsAmong the 68 patients 49 were male and 19 were female aged 6 to 77 years old. The most common clinical manifestations were cough, sputum and fever. Inflammatory indicators was slightly elevated. The most common site was on the right upper lung. The typical CT manifestations were the low-density liquefaction necrotic zone in the center of the mass with vacuoles of different sizes, namely, "air-space consolidation". Positron emission computed tomography showed a mild metabolic increase in lesions. The 68 patients were confirmed by surgery, CT guided percutaneous lung puncture or bronchoscopic biopsy. The average time of the diagnosis was 10 months while the longest time was 6.4 years. The rate of first diagnosis was 5.9%. Forty-one cases were treated with antibiotics alone and 12 cases were treated with simple operation, the rest were treated by antibiotics combined with surgical treatment. The cure rate was 88.7%. Although active treatment was conducted 3 patients in this hospital were not cured.ConclusionsThe clinical features of pulmonary actinomycosis are atypical and the misdiagnosis rate is high. When pulmonary actinomycosis is suspected, it should be fully communicated with the microbiologist to ensure the cultivation in anaerobic environment and extension of the incubation cycle. Tissue culture and pathological biopsy should be actively performed. Treatment depends on antibiotics or surgery with good prognosis, but for some cases the prognosis is not optimistic.
ObjectiveTo analyze risk factors, clinical features and outcome factors of invasive pulmonary aspergillosis (IPA) in severe H1N1 patients so as to achieve early diagnosis and improve prognosis.MethodsFifty severe H1N1 influenza patients with IPA admitted to West China Hospital and 64 severe H1N1 influenza patients in the same period matched by age and gender were collected. Patient characteristics, laboratory examinations, radiological imaging, microbiology data and prognostic indicators were involved into analysis.ResultsThe mortality of severe H1N1 influenza patients with IPA was significantly higher than those without IPA (51.6% vs. 32.0%, P=0.036). However, the incidence of IPA in severe H1N1 influenza patients was not related with the patient's age, gender, underlying disease, glucocorticoid use and CD4+ T cell count. Serum C-reactive protein level [(125.0±88.8) vs. (86.1±80.1) mg/L, P=0.038] and interleukin-6 level [(148.7±154.2) vs. (81.7±110.2) μg/L, P=0.039] of severe H1N1 influenza patients with IPA were significantly higher than those without IPA. Besides, more patients presented with fever (81.3% vs. 64.0%, P=0.038) and dyspnea (51.6% vs. 24.0%, P=0.003) in severe H1N1 patients with IPA. The radiological imaging of severe H1N1 patients with IPA were mostly characterized by combining with nodular changes on the basis of ground-glass opacity.ConclusionThe occurrence of IPA in severe H1N1 influenza patients may be related with pulmonary excessive inflammatory response secondary to viral invasion rather than basic condition of the patient.
ObjectiveTo analyze the clinical presentations and radiological characteristics of pulmonary vein stenosis after radiofrequency ablation. MethodsClinical and radiological data of 2 patients with pulmonary vein stenosis after radiofrequency ablation for atrial fibrillation were retrospectively analyzed and literatures were reviewed. ResultsBoth patients had undergone circumferential pulmonary vein isolation. The symptoms appeared approximately 2 months after the operation. The major symptoms were cough, hemoptysis, exacerbation of dyspnea and chest pain. Both patients were misdiagnosed as other diseases such as pneumonia in other hospitals, and the anti-infection therapy was invalid. Both CT scans showed parenchymal exudative consolidation with varying degrees of interstitial septal thickening and small nodules. Both patients were confirmed as pulmonary vein stenosis by CT angiography. Literature review identified 21 cases of pulmonary vein stenosis after radiofrequency ablation for atrial fibrillation. The main clinical features are hemoptysis, chest pain, shortness of breath and cough. The most common features of thoracic radiological imaging are consolidation, groud-glass attenuation, pleural effusion and interstitial septal thickening. ConclusionsIf a patient presents with hemoptysis, dyspnea, chest pain or other clinical manifestations after ablation therapy and image findings show parenchymal exudative consolidation with interstitial septal thickening and multiple small nodules, the possibility of pulmonary vein stenosis should be considered. Contrast-enhanced CT combined with pulmonary vein imaging technology can clearly show the opening diameter of each pulmonary vein and its branches, so it is an important non-invasive examination method for the evaluation and diagnosis of pulmonary vein stenosis.
ObjectiveTo analyze the epidemiological and clinical characteristics of severe cases of coronavirus disease 2019 (COVID-19) in order to provide reference for clinical diagnosis and treatment.MethodThe epidemiological histories, clinical characteristics, laboratory examinations, chest images, and treatment outcomes of 20 confirmed cases of severe COVID-19 admitted to Public Health Clinical Center of Chengdu from January 16th to February 5th, 2020 were retrospectively analyzed.ResultsAmong the 20 patients with severe COVID-19, 12 were male and 8 were female. The age ranged from 34 to 84 years old, with an average of (57.4±16.5) years old. Thirteen patients (65.0%) had one or more co-existing diseases, such as hypertension (9 cases), diabetes (6 cases), and coronary atherosclerotic heart disease (4 cases). Eleven cases (55.0%) had a history of living or traveling in Wuhan, 4 cases (20.0%) had a history of living in non-Wuhan areas of Hubei Province, 3 cases (15.0%) had a history of contact with confirmed COVID-19 patients, while 2 cases had no above-mentioned epidemiological history, but had a history of traveling in non-epidemic areas. The main symptoms were fever (100.0%), cough (100.0%), shortness of breath (75.0%), and fatigue (65.0). Some patients developed into acute respiratory distress syndrome in 3-10 d after onset. The white blood cell count of the patients was normal or decreased, the hypersensitive C-reactive protein and serum amyloid protein significantly increased, while the CD4+ T lymphocyte count and CD56+ natural killer cell count significantly decreased. Sixteen patients (80.0%) were given transnasal hyperbaric oxygenation [among whom 6 patients (30.0%) were transferred to non-invasive ventilator after no improvement], 3 patients (15.0%) were given tracheal intubated ventilator, and 1 patient (5.0%) was treated by tracheal intubated ventilator combined with extracorporeal membrane oxygenation to support breathing. By April 8th, 2020, 3 patients died and the remaining 17 had been cured and discharged, with an average length of hospital stay of 21.4 d. The 3 death cases were all elderly with underlying diseases such as heart disease and pulmonary disease.ConclusionsSevere COVID-19 is associated with hypertension, diabetes, heart disease, and other basic diseases, and some patients develope acute respiratory distress syndrome. Respiratory support may help to improve prognosis.
Objective To explore the clinical features of microscopic polyangiitis ( MPA )complicated with pulmonary involvement in comparison with idiopathic pulmonary fibrosis ( IPF) . Methods Clinical and laboratory data of 27 patients with MPA and 56 patients with IPF in the Drum Tower Hospital from2006 to 2010 were analyzed retrospectively. The differences were compared between the MPA patients with pulmonary fibrosis manifestation ( MPA/PF patients) and those without pulmonary fibrosis manifestation( MPA/NPF patients) , and the IPF patients. Results The differences between the MPA/PF patients and the MPA/NPF patients were rarely found in terms of respiratory symptoms, ANCA positive rate, and multiple organ involvement, but the proportions of suffering severe renal damage and severe pulmonary hypertension in the MPA /PF patients were relatively high ( P lt; 0. 05) . Furthermore, there were significant differences between the MPA/PF patients and the IPF patients in terms of dyspnea, incidence of renal damage, ANCA positive rate, incidence of serious pulmonary hypertension, and multiple organ involvement. The IPF patients were more prone to develop dyspnea while MPA patients were more prone to develop renal damage, high ANCA positive rate, high incidence of serious PAH and multiple organ involvement, such as rush, joint pain,weight loss, fever and gastrointestinal symptoms ( P lt;0. 05) . Conclusions When patients have respiratory symptoms complicated with renal failure, skin damage, fever, and joint pain, the diagnosis of MPA should be considered. For patients who were clinically suspected as interstitial pneumonitis or pulmonary fibrosis,measurement of serumantineutrophil cytoplasmic antibodies and creatinine test are essential for diagnosis.
ObjectiveTo analyze the clinical radiographic features and treatment of interstitial lung disease (ILD) inpatients infected with influenza virus. MethodsThe clinical data of ILD patients with influenza in Nanjing Drum Tower Hospital from October 2023 to January 2024 were collected. According to each patient results of influenza nucleic acid detection, they were divided into an influenza infection group and a non-infection group. ResultsA total of 73 patients received influenza nucleic acid detection were enrolled, 23 cases including 5 males and 18 females were positive. Twenty-one cases were infected with influenza A virus, 2 cases were infected with influenza B virus. The median age of influenza positive patients was 64.7±7.8 years. Cough (23 cases, 100.0%), sputum (23 cases, 100.0%), wheezing (20 cases, 87.0%) and fever (17 cases, 73.9%) were the most common symptoms of the patients infected with influenza. Compared with the non-infection patients, fever was more common in the influenza infection group (P<0.05). Laboratory examination indicated that lymphocytopenia were detected in the influenza infection patients. There was no statistical difference in the level of white blood cell count, neutrophil count, lactate dehydrogenase, creatine kinase, erythrocyte sedimentation rate, C-reactive protein, calcitonin, interleukin-6 and oxygenation index. Ground glass opacity in the influenza virus infection group was more common than that in the non-infection group (P<0.05). Ten ILD patients infected with influenza virus (43.5%) were co-infected with Aspergillus. The chest CT type of ILD patients with Aspergillus infection was usual interstitial pneumonia (UIP). Honeycombing was more common than those without Aspergillus infection group (P<0.05). Twenty-two patients (95.7%) received antiviral treatment, of which 20 patients (87.0%) were treated with oseltamivir, 5 patients (21.7%) were treated with mabaloxavir, and 4 patients (17.4%) were treated combined with paramivir. Seventeen patients (73.9%) were previously treated with glucocorticoids, and 16 patients did not adjust the glucocorticoids dosage; 9 patients (39.1%) were previously treated with immunosuppressants, and 2 patients stopped immunosuppressants. Four patients (17.4%) infected with influenza virus developed acute exacerbation of ILD. There was no statistically significant difference in acute exacerbation between the two groups (P>0.05). ConclusionsCompared with ILD patients not infected with influenza, fever, lymphocytopenia and ground-glass opacity are the common clinical and chest CT features of ILD patients infected with influenza. Patients with UIP type combined with honeycomb were prone to be co-infected with Aspergillus infection.
ObjectiveTo investigate the clinical features of elderly hip fracture in Leshan area in China. MethodsThe clinical data of patients with hip fractures from June 2006 to January 2013 were retrospectively analyzed. Gender, age, fracture type, injury causes, activities before injury and treatment were analyzed. ResultsThe mean age of patients with a hip fracture was 76.5 years. The overall male to female ratio with hip fracture was 1:1.44. There were 154 patients (50.0%) with femoral neck fracture, 138 patients (44.8%) with intertrochanteric fracture, and 16 patients (5.2%) with subrtrochanteric fracture. A total of 248 patients (77.3%) were poorly educated, and 210 patients (68.2%) had basic medical insurance. The mean time between being injured and hospitalized after injury was 3 days. There were 257 patients (83.4%) with fall damage. ConclusionFemale patients with hip fracture are more than male patients. Fall damage is the main injure type. The features of elderly hip fracture in Leshan include retardation to consult a doctor, poor education of the patients, dependence primarily on basic medical insurance and under-emphasis of anti-osteoporosis therapy.
Objective To observe the clinical characteristics and influencing factors of post-stroke epilepsy. Methods Our research wasaretrospective study, the data came from the information of patients diagnosed with post-stroke epilepsy from our hospital on October 2000 to December 2014 withatotal of 160 cases. With the general collection of clinical data, including gender, past history, clinical manifestations, laboratory examinations and treatment informations. Results The shortest time of post-stroke seizures were occur immediately, the longest was 15 years after the stroke. Peak onset is as early as onset of stroke immediately, late-onset seizures after stroke peaks between 6 months to 1.5 years. 59 patients occurred early epileptic seizures, partial seizures were the most common, accounting for 47.46%; 101 patients occurred late epilepsy, generalized tonic-clonic seizures were the most common, accounting for 56.44%. 25% of patients wereasingle-site lesions, the most common site was temporal lobe; 75% of patients were multifocal lesions. Most were located in the temporal lobe, frontal lobe and the basal ganglia. 42 cases of patients performed EEG, 30 patients (71.43%) of the EEG abnormalities, including 22 cases (73.33%) recurrent epileptic seizures; 12 cases (28.57%) patients with an edge or normal EEG, including 3 cases (25%) relapsed. 54.38% patients with drug therapy to single-agent therapy, two patients with refractory epilepsy to be combination therapy. Conclusions This group of post stroke epilepsy patients were more common as late-onset epilepsy, early onset of stroke peaks is the first day, and delayed the onset of the peak after stroke is within 6 months to 18 months. Lesions in the cortex:alarge area and multiple lesions were risk factors for post-stroke epilepsy, cortical damage to the temporal lobe is most prevalent. 71.43% of patients may have abnormal EEG, EEG abnormalities have higher relapse rate in patients with epilepsy.
Objective To investigate clinical features and surgical outcome in children with frontal lobe epilepsy by evaluating the correlation between the predictive factors and seizure freedom. Methods 18 children who underwent frontal lobe epileptogenic resection in the Epilepsy Center of the Children's Hospital of Fudan University between January 2017 and December 2019 with a minimum follow up of 2 year were analyzed retrospectively. Each patient was evaluated with detailed data to predict postsurgical seizure freedom by analysis of variance. Results Of the 18 patients, there were 11 males and 7 females, the age at surgery ranged from 21 months to 11 years old (6.8±2.73) and the duration of seizures was from 1 month to 9 years. 17 patients had focal seizures, while 1 had generalized epileptic spasm. In scalp EEG, interictal and initial ictal discharges were frontal in 11 and 9 cases, respectively. MRI was indicative of FCD in 10 cases, tumor in 2, tuberous sclerosis and gliosis lesion in 1 case each. 4 patients were MRI negative. 11 patients underwent epileptogenic lesion resections directly and 7 cases received depth electrodes implantation and underwent stereo-electroencephalography to localize epileptogenic zone. At follow-up of 2 years, 14 (77.8%) patients remained seizure-free (Engel Ⅰ), 1 (5.6%) had marked seizure reduction (Engel Ⅱ), 2 (11.0%) showed minor improvement (Engel Ⅲ), and only 1 (5.6%) showed no response (Engel Ⅳ). About predictors of seizure recurrence, there were no significant differences in gender, age at surgery, age of seizure onset, duration of epilepsy, lateralization of epileptogenic zone, positive MRI findings, interictal and ictal discharge, etiology, intellectual development and stereo-electroencephalography implantation, while significantly higher rates of seizure freedom correlated with complete the resection of the epileptogenic zone. Conclusions Focal cortical dysplasia is the most common cause in childhood with frontal lobe epilepsy and complete resection of the epileptogenic zone can lead to good seizure control outcome.
