ObjectiveTo investigate the clinical characteristics of non-tuberculous mycobacterium (NTM) pulmonary disease and pulmonary tuberculosis, as well as the bacterial distribution of NTM pulmonary disease. Methods The bacterial distribution and clinical characteristics of 104 patients with NTM lung disease hospitalized in Jiangxi Provincial People’s Hospital from May 2017 to May 2020 were retrospectively analyzed, as well as the clinicplal characteristics of 155 patients with tuberculosis hospitalized during the same period. Results The age of NTM lung disease group [(60±15) years] was higher than that of tuberculosis group [(55±19) years]. There were statistically significant differences in basic diseases (such as malignant tumor, type 2 diabetes, old tuberculosis, bronchiectasis), laboratory examination (such as blood routine examination, albumin) and chest imaging characteristics between the two groups (P<0.05). There was no significant difference in clinical symptoms (such as cough, sputum or fever) (P>0.05). The common underlying diseases of NTM lung disease were malignant tumor (29%), bronchiectasis (21%), chronic obstructive pulmonary disease (19%), etc. The common clinical symptoms of NTM lung disease included cough, sputum, fever, hemoptysis, chest tightness and shortness of breath, and other non-specific respiratory symptoms. The common manifestations of NTM lung disease on chest high-resolution CT (HRCT) included patchy images (82%), mediastinal lymph node enalargement (35%), pleural thickening (31%), pleural effusion (26%) and other signs. The isolates of NTM included Mycobacterium avium (50%), Mycobacterium intracellulare (21%), Mycobacterium chelonae/abscessus (14%), Mycobacterium fortuitum (5%), Mycobacterium gordonae (4%), Mycobacterium gilvum (3%), and Mycobacterium smegmatis (3%). Multivariate Logistic regression analysis showed that advanced age (OR=1.027) was a risk factor for NTM lung disease. Conclusions The clinical manifestations of NTM lung disease and tuberculosis are similar and difficult to distinguish. For male patients over 60 years old with malignant tumor, old tuberculosis, bronchiectasis and other basic diseases, and the chest HRCT findings are mainly bronchiectasis, NTM lung disease should be actively excluded. There is little difference in clinical manifestations between different strains of NTM lung disease, and the treatment cycle of NTM lung disease is long and easy to be interrupted, requiring enhanced follow-up.
Objective To improve the knowledge of cryptogenic organizing pneumonia ( COP) , and reduce misdiagnosis and mistreatment. Methods The medical records of 22 patients with biopsy-proven COP from January 2006 to October 2011 were retrospectively reviewed. The clinical presentation, laboratory data, radiographic results and treatment were collected and analyzed. Results The clinical presentations were nonspecific, and the most common symptomof COPwas cough ( 95. 45% ) . The laboratory data analysis revealed that elevated erythrocyte sedimentation rate in 71. 43% of the COP patients. The COP patients usually presented with a restrictive ventilation dysfunction and decreased diffuse function on pulmonary function test. The most common patterns of lung abnormality on chest CT scan were bilaterally multifocal patchy consolidation or ground-glass opacification ( 63. 64% ) , which distributed along the bronchovascular bundles or subpleural lungs. Patchy consolidation with air bronchograms was also a common feature ( 54. 55% ) . Migration over time and spontaneous remission of consolidation were important pointers.Histopathology by transbronchial lung biopsy was a valuable means for diagnosis. The majority of COP patients were non-response to antibiotics, but responded rapidly and completely to oral administration of corticosteroids with good prognosis. Conclusions The clinical presentations and laboratory data of COP patients are nonspecific. Initial imaging findings of COP are similar with pneumonia. Strengthening the recognition of COP is conducive to reducing misdiagnosis and reasonable antibiotics use.
ObjectiveTo investigate the etiology, clinical features and treatment of familial exudative vitreoretinopathy (FEVR) secondary glaucoma. MethodsA retrospective clinical study. From January 1, 2016 to January 1, 2022, 15 patients (17 eyes) were diagnosed with FEVR secondary glaucoma in Beijing Tongren Hospital, Capital Medical University were included in the study. All patients underwent systematic ophthalmological evaluation. According to the patient's age, visual acuity, intraocular pressure, anterior segment, vitreous body and retina condition, the choice of translimbal lensectomy combined with vitrectomy, goniectomy, cyclophotocoagulation, intravitreal injection of anti-vascular endothelial growth factor (VEGF) treatment were chosen. The follow-up time was 3 to 37 months. The clinical characteristics of the affected eye, and the changes of intraocular pressure, anterior chamber depth and complications after surgery were observed. ResultsAmong the 15 patients, there were 11 males with 13 eyes, and 4 females with 4 eyes. Age was 6.14±7.37 years old. FEVR stages 2B, 3B, 4A, 4B, 5A, and 5B were 1, 1, 5, 6, 3, and 1 eye, respectively. The intraocular pressure of the affected eye was 42.74±9.06 mm Hg (1 mm Hg=0.133 kPa). All eyes had shallow anterior chamber and angle closure, anterior or posterior iris adhesions, lens opacity, retinal detachment, iris neovascularization in 4 eyes, and vitreous hemorrhage in 2 eyes. Sixteen eyes were treated with translimbal lensectomy combined with vitrectomy and goniotomy, of which 8 eyes were treated with anti-VEGF treatment; 1 eye was treated with cyclophotocoagulation combined with anti-VEGF treatment. After operation, the intraocular pressure of 16 eyes returned to normal range, and the depth of anterior chamber of 16 eyes returned to normal, and no obvious complications occurred. ConclusionsThe main etiology of secondary glaucoma in FEVR is the structural and functional abnormalities of the anterior chamber and angle, which are found in the 2B and above stages of FEVR. The lensectomy and vitrectomy via limbal approach can effectively control the intraocular pressure and restore the anterior chamber, with no serious complications.
ObjectiveTo summarize the clinical features of pulmonary mucoepidermoid carcinoma (PMEC) and improve the level of the diagnosis and therapy.MethodsA case of PMEC was reported and related literatures were reviewed in PubMed, WanFang data and China National Knowledge Infrastructure.ResultsA 21-year-old female patient, complaining of cough and expectoration for 5 months, intermittent hemoptysis for 3 months and repeated fever more than 4 days, was hospitalized in March 2017. After admission, the patient was diagnosed as low-grade PMEC and received anti-infection, fibrobronchoscope sputum aspiration and alveolar lavage therapy. During the hospitalization, the anti-infection of the patients was not much effective, and the chest CT examination suggested space-occupying lesions in the middle lobe of the right lung. After the surgical removal of the right lung, the syndrome of the patient was improved. A total of 13 patients were reviewed, there was no obvious gender difference, and the median age was about 40 years old (most frequently occurred in younger adults with an average age less than 50 years). Frequent clinical manifestations were cough, fever and hemoptysis, which were often accompanied with atelectasis. Most of the patients could be improved after surgical resection, and a few need comprehensive treatment including radiotherapy, chemotherapy and targeted treatment, etc.ConclusionsPMEC is rare and the etiology is still unclear. The pathology is mainly low-grade. Majority of patients with PMEC could be cured after surgical resection.
Objective To investigate the clinical characteristics of neutrophilic asthma ( NA) .Methods NA patients were collected from the out-patient and in-patient departments of Respiratory Diseases of Xinqiao Hospital between January 2010 and December 2010. The results of the medical records,pulmonary function tests, and induced sputum cytology were analyzed retrospectively. Results The NA patients with neutrophil percent ≥ 61% accounted for 33. 1% ( 51 /154 ) of all the asthmatics patients detected by induced sputumin the same period, and 45 cases with complete records were included. Of the 45 cases recruited, 20 cases ( 44. 4% ) were in-patients,2 cases ( 4. 4% ) were with controlled asthma, 3 cases ( 6. 7% ) were with cough variant asthma, 30 cases ( 66. 7% ) were female, 12 cases ( 26. 7% ) were atopic patients, and 27 cases ( 60% ) had acute exacerbation. The age of onset of 35 patients ( 77. 8% ) were after 12 years. FEV1% pred lt; 60% and gt; 80% was obtained in 55. 9% ( 19/34) and 14. 7% ( 5 /34) of patients respectively. The result of bronchodilator test was positive in 64% ( 16/25) of patients, and mean increase in FEV1 was 11. 7% . The percentage of neutrophil and eosinophil was ( 74. 5 ±9. 1) % and ( 2. 4 ±2. 5) % respectively in induced sputum, and 35. 6% ( 16/45) of the patients had increased eosinophil percentage ( gt;3% ) . Conclusions In our study, most of NA is severe and acute exacerbation asthma, and its clinical features are various. The mechanismand clinical significance of increased neutrophils in asthmatic patients are unclear and more studies are needed.
Objective To summarize the clinical features, diagnosis and treatment of postinfection bronchiolitis obliterans. Methods Clinical manifestation, chest X-ray, characteristics of lung function,computed tomography ( CT) of 6 patients with postinfection bronchiolitis obliterans from August 2009 to June2012 were analyzed retrospectively.Results All 6 cases were diagnosed as bronchiolitis obliterans after pneumonia. One patient had severe pneumonia complicated with congenital atrial septal defect and heart failure. 3 cases were complicated with varying degrees of cardiac insufficiency. Adenovirus in sputumsample were found in2 cases, smear positive for parainfluenza virus was found in1 case, mycoplasma were found in 2 cases, and no specific pathogen was found in the last one. All 6 cases were suffered frompersistent cough,wheezing and shortness of breath with three depression sign in 4 cases. The symptoms lasted for at least 6 weeks. Crackles and wheezing were present in all 6 cases. Small airway lesion was presented by pulmonary CT. Bronchiectasis was showed in 2 cases, atelectasis in 1 case, and consolidation in 1 case. Pulmonary function tests showed mixed ventilatory dysfunction. Bronchofiberscope examination was operated in5 cases,only endotracheitis was found. Prednisone and azithromycin were given orally in all the cases, but the clinical symptoms were persistent in the course of treatment and no death occured. Conclusions Clinical symptoms of bronchiolitis obliterans are characterized by persistent cough and wheezing. Small airway lesions were present in pulmonary CT. Repeated lower respiratory infection is common. Prednisone is widely used in treatment of bronchiolitis obliterans, but the therapeutic effect is uncertain.
ObjectiveTo enhance the understanding of Takayasu’s arteritis (TA) with pulmonary vascular involvement through the analyses on clinical features.MethodsA retrospective study was conducted to analyze the clinical records of patients diagnosed as TA with pulmonary vascular involvement admitted to Beijing Anzhen Hospital from January 2007 to August 2017.ResultsIn recent 10 years, there were 233 patients diagnosed as TA in Beijing Anzhen Hospital, 17 of them were involved with pulmonary arterial, which accounted for 7.3%. Fourteen patients were females, 3 patients were males. The age ranged from 16 to 59 years with an average of (40±13) years. Among the 17 patients, dyspnea (15 cases, 88.2%) was the most common symptom, and unequal blood pressure of upper limbs (9 cases, 52.9%) was the main sign. Thirteen patients had pulmonary hypertension by echocardiographic examination. Angiographic data showed that multi-lobular and multi-segmental pulmonary branches were predominantly affected. Unilateral involvement of pulmonary artery was more common than bilateral involvement, while the right pulmonary arteries were more often affected than the left. Thirteen patients received hormone and immunosuppressive therapy, 11 patients received anticoagulation or antiplatelet therapy, and 5 patients received targeted treatment of pulmonary artery pressure.ConclusionsThe clinical manifestation of TA is unspecific and misdiagnosis rate is relatively high. Improving the understanding of TA is necessary so as to reduce the misdiagnosis rate at an early stage and ameliorate the prognosis.
【Abstract】 Objective To investigate the clinical characteristics and prognosis of secondary lymphocytic interstitial pneumonia ( LIP) . Methods Clinical data of 9 cases with secondary LIP diagnosed from1990 to 2010 were retrospectively analyzed. Results Of 9 patients there were 3 males and 6 females,the range of age was 7-64 years. In the 6 adult patients there were 5 females. 2 cases were infected by EB virus and 1 by recurrent pulmonary infection in 3 non-adult patients. In the adult patients, 1 case was diagnosed with Sjogren’s syndrome, 1 case with overlapping syndrome, 2 cases with primary biliary cirrhosis,1 case was probably caused by infection, and 1 case was complicated with eosinophilia. Dominant symptoms of pulmonary system were cough, expectoration, and shortness of breath on exertion. Dominant systematic symptoms were asthenia, pyrexia, weight lose, and arthralgia. CT revealed diffuse ground glass opacities with a lower lung zone predominance. Pathologic feature of LIP was a diffuse, polyclonal lymphoid cell infiltration surrounding airways and extending to the lung interstitium. The patients were treated by glucocorticoid and immunosuppressants. Two cases died with secondary infection. Follow-up did not comfirm malignant tumors in the survivors. Conclusions The clinical features of LIP are characteristic, but lacking of specificity. The final diagnosis depends on pathological examination. Treatment targeted on primary diseases can probably have a good efficacy, and the clinical outcome is favorable.
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 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.
