Objective To summarize the clinical features of lymphangioleiomyomatosis ( LAM) in Chinese population. Methods The first case of LAM in China was reported in 1981. All cases of LAM reported in Chinese literature from January 1981 to December 2009 were reviewed. The cases for analysis were included with a diagnosis of LAM confirmed or probable according to the guidelines of European Respiratory Society, and with individual clinical data available. Results A total of 111 cases of LAM werepooled for analysis. All cases were female. The most frequent onset symptomof LAMwas dyspnea ( 51. 4% ) .The main clinical manifestations included dyspnea ( 93. 4% ) , pneumothorax ( 48. 6% ) , cough ( 45. 7% ) ,hemoptysis ( 35. 1% ) , and chylothorax ( 33. 3% ) . 11 cases were associated with tuberous sclerosis complex.An obstructive with or without restrictive abnormality in pulmonary function testing was observed in 60 /67 cases. Diffusion impairment was also common ( 45 /46) . Of the 109 patients, computerized tomography of chest showed thin-walled air-filled cysts throughout both lungs in 104 cases, multiple bullae in 3 cases, andhoneycomb changes in 2 cases. 102 cases were diagnosed based on pathological findings. Misdiagnosis was found in 44 cases, the median time of misdiagnosis was 24 months. Conclusion Awareness of LAMshould be raised when an adult female who presents with an unexplained dyspnea, especially combined with repeatedpneumothorax or chylothorax.
Objective To investigate the diagnosis and treatment of congenital choledochal cysts(CCC) in children. MethodsThe manifestation, auxiliary examination, mode of operation and effect of 42 patients with CCC in children from Jan., 1980 to June, 1999 were analyzed retrospectively.Results The patients with the triad of jaundice, an abdominal mass, and pain was 38.1% among the 42 patients. B-ultrasonic diagnosis was made with a correct diagnostic rate of 95.2%. The effective rate of internal drainage was significantly lower than that of resection of the cyst(χ2=19.36, P＜0.001) while the reoperation rate and incidence of carcinoma of internal drainage were higher than those of resection of the cyst(χ2=11.59, P＜0.001 and χ2=4.97, P＜0.05). Conclusion B-ultrasonic diagnosis is recommended as the first examination method. Internal drainage should be abandoned. Resection of the cyst with Roux-Y hepaticojejunostomy is recommended as the treatment of choice on extrahepatic cholangiectasis. Liver transplantation is a reasonable choice to treat the diffuse intrahepatic cholangiectasis.
【Abstract】Objective To analysis the clinical characteristics, pathogenesis, diagnosis and treatment of acute acalculous cholecystitis.Methods Seventy-nine cases of acute acalculous cholecystitis from January 1996 to January 2003 were retrospectively reviewed.Results Of those 79 cases, 13 cases were treated nonoperatively and 66 cases were treated operatively. Twentythree cases were suppurative, 43 cases were gangrenous with perforation in 18 cases，which were proved by postoperative pathology. Seventysix cases were cured and 3 cases were dead. Conclusion Keeping vigilant alert, observing dynamically as well as appropriate operative intervention are effective to improve the prognosis of acute acalculous cholecystitis.
Objective To elucidate the clinical features and treatment of parapneumonic effusions ( PPE) . Methods Ninety-seven patients were analyzed retrospectively in Guangzhou First Municipal People’s Hospital fromJanuary 2004 to July 2008. The data of 54 patients with complicated parapneumonic effusion ( CPPE) and 9 cases with empyema were compared with 49 patients with tuberculosis pleural effusions. Results Of 97 cases, 34 patients with uncomplicated parapneumonic effusion ( UPPE) were treated with antibiotics only, whose hospitalization time was ( 14. 8 ±7. 6) days, and 27 cases were cured ( 79. 4% ) . Of 54 CPPE patients, 42 were treated with antibiotics and pleural space drainage with central venous catheter, whose hospitalization time was ( 21. 7 ±13. 0) days, and 32 were cured ( 76. 2% ) . Another12 CPPE patients were treated with interapleural urokinase and drainage from the chest tube, whose hospitalization time was ( 22. 5 ±9. 3) days, and 8 were cured ( 66. 7% ) . Nine cases with empyema were rinsed the pleural with metronidazole solution, whose hospitalization time was ( 25. 7 ±17. 4) days, and 8 were cured( 89. 0% ) . Compared with the tuberculous pleurisy patients, most CPPE and empyema occurred in middle and old aged patients with an average age of ( 63. 3 ±19. 3) years. Polykaryocyte and lactate dehydrogenase increased significantly. Adenosine deaminase ( ADA) was lt; 45 U/L in most UPPE and empyema patients, but was gt; 45 U/L in 7 cases ( 11% ) . Conclusions UPPE is simple and preferably treated with antibiotics alone. While CPPE and empyema should be drainaged as early as possible, and the low-dose urokinase may be helpful. The level of ADA can not absolutely distinguish parapneumonic effusion from tuberculous pleural effusion.
Objective To investigate the diagnosis, indications for surgery, operative methods and prognostic factors of surgical resection for pulmonary metastases, and improve the survival rate of patients with pulmonary metastases . Methods A total of 125 patients with pulmonary metastases underwent 138 metastasectomies,116 patients had metastasectomy once while 5 patients underwent a second metastasectomy and 4 patients a third metastasectomy. There were 66 wedge resections,2 segmentectomies, 53 lobectomies,2 en bloc resections of chest wall plus lobectomy,3 pneumonectomies and 12 precision resections. Surgical approaches included 130 thoracotomies and 8 videoassisted thoracic surgery. Results The primary tumor sites were epithelial in 94 patients ,sarcoma in 26 and others in 5. There was no perioperative mortality. A total of 122 patients were followed up , followup time was 1-10 years. The 1-, 3-, and 5-year survival rates were 90.4%, 53.3%, and 34.8% respectively. Better prognoses were found in patients with colorectal cancer, renal cancer and soft tissue sarcoma, the 5-year survival rates were 43.8%, 37.5%, and 33.3% respectively. For the 105 patients whose pulmonary metastases were resected completely, the 5-year survival rate was 38.9%. The 5-year survival rate was only 16.7% for 20 patients with incomplete resection, however. Systematiclymph node dissection had been performed in 89 patients but metastases were identified only in 12 patients. The 5-year survival rates were 14.3% for node positive patients and 41.5% for node negative patients. Conclusion Surgical resection for pulmonary metastases should be performed in properly selected patients and successful outcomes can be achieved. Posterolateral minithoracotomy is the most common surgical approach. The completeness of resection and the status of mediastinal lymph nodes may be important prognostic factors.
ObjectiveTo observe and assess the clinical value of electrophysiology of ocular surface in the diagnosis and treatment of blepharospasm in Meige syndrome (MS). MethodsA single-center, cross-sectional study. A total of 413 patients diagnosed with MS and undergoing surgical treatment at the Henan Provincial Meige Syndrome Diagnosis and Treatment Center of the Henan Provincial Third People′s Hospital from May 2022 to December 2023 were included as the MS group. A total of 110 age- and gender-matched spouses of patients and community volunteers were selected as the control group. The bioelectricity detection program of the electrooculogram was used; the frequency bandwidth was set at 0.3 to 300.0 Hz. Surface electrodes were employed to record the surface electrophysiological manifestations of the corrugator supercilii muscle and the lower orbicularis oculi muscle, as well as the conditions and temporal characteristics of spasm waves. Based on the amplitude and waveform of the electrophysiology of ocular surface signals, it can be classified into 0-4 grades. The blepharospasm was divided into conditionally induced type, spastic type, reverse spastic type, and oro-ocular elicited type. All patients were treated with neural circuit occlusion, and the postoperative follow-up time was 4.1 (0.5-19.0) months. The distribution of different grades of electrophysiology of ocular surface in the MS and control group at baseline were observed, as well as within the MS group at the last follow-up visit. Additionally, the blepharospasm grades in the MS group were also assessed. The comparison of the distribution of the number of eyes with different grades of electrophysiology of ocular surface between groups was conducted using the Mann-Whitney U test. ResultsAt baseline, in the MS group, the number of cases with corrugator supercilii muscle amplitudes and morphologies graded from 0 to 4 were as follows: 15 (3.60%, 15/413) for grade 0, 95 (23.00%, 95/413) for grade 1, 142 (34.38%, 142/413) for grade 2, 127 (30.75%, 127/413) for grade 3, and 34 (8.24%, 34/413) for grade 4. In the control group, the corresponding numbers of individuals were 82 (74.54%, 82/110) for grade 0, 24 (21.82%, 24/110) for grade 1, 4 (3.64%, 4/110) for grade 2, 0 (0.00%, 0/110) for grade 3, and 0 (0.00%, 0/110) for grade 4. For the orbicularis oculi muscle, there were 35 cases (8.47%) in grade 0, 124 cases (30.03%) in grade 1, 150 cases (36.32%) in grade 2, 90 cases (21.79%) in grade 3, and 14 cases (3.39%) in grade 4 in the MS group. In the control group, there were 86 cases (78.18%) in grade 0, 24 cases (21.82%) in grade 1, and 0 cases in grades 2, 3, and 4. There were statistically significant differences in the distribution of the number of eyes with different electrophysiology of ocular surface grading of the corrugator supercilii muscle and the orbicularis oculi muscle between the MS and control group (Z=−14.51, −13.86; P＜0.001). Meanwhile, there were statistically significant differences in the distribution of the number of eyes with different electrophysiology of ocular surface grading of the corrugator supercilii muscle and the orbicularis oculi muscle between preoperation and at the last follow-up in the MS group (Z=−16.52, −17.36; P＜0.001). In the MS group, there were 61 (14.77%, 61/413), 306 (74.09%, 306/413), 27 (6.54%, 27/413) and 19 (4.60%, 19/413) cases of blepharospasm conditionally induced type, spasm type, reverse spasm type and oro-ocular elicited type, respectively. ConclusionThe electrophysiology of the ocular surface can objectively reflect the activity of periocular neuromuscular.
ObjectiveTo investigate the diagnosis and classification of chronic obstructive pulmonary disease (COPD) in high risk populations living in metropolitan communities of Beijing. MethodsDuring January 2011 to December 2012,a cross-sectional survey including questionnaires and pulmonary function tests were performed in high risk populations of COPD (aged≥40 years with a history of smoking or chronic bronchitis) at 6 communities in Dongcheng District of Beijing. For those confirmed to have COPD,the dyspnea was rated by the modified Medical Research Council Dyspnea Scale (mMRC),and the frequency of acute exacerbations in the last year was recorded. The patients were classified by the Global Initiative for Chronic Obstructive Lung Disease (GOLD 2011) classification criteria. ResultsA total of 932 individuals,including 689 males (73.9%,aged 60.8±12.5 years) and 243 females(26.1%,aged 59.8±12.1 years),who had risk factors of COPD were included in the screening. COPD was confirmed in 203 patients,with the prevalence of 21.8%,and among whom only 31 cases (15.3%) had been diagnosed as COPD in the past. According to the revised GOLD classification in 2011,96(47.2%),38(18.7%),56(27.5%),and 13(6.4%) patients were classified into group A,B,C and D,respectively. The proportion of subgroup C1 (FEV1%pred <50% and the number of exacerbation in the last year <2) in group C was 71.4% (40/56). ConclusionIn the metropolitan communities of Beijing,screening the population with predisposing factors can increase the early diagnosis of COPD,which is often delayed by the lack of significant symptoms. The high proportion of patients in group C in this population implies that disease screening in high risk populations may be helpful for the prevention and treatment of COPD.
Objective To summarize the diagnosis and treatment of synchronous multiple primary malignant tumors in lung. Methods The clinical and pathological data of 5 cases with intrapulmonary synchronous multiple primary cancer, who were diagnosed in recent 10 years in Xinhua Hospital, were retrospectively analyzed. Results The incidence of intrapulmonary synchronous multiple primary cancer was 0. 21%( 5 /2380) in all lung cancer cases diagnosed in respiratory department of Xinhua Hospital. There were 4 males and 1 female, with the average age of 60. 2 years old. Five patients were all treated with surgical operation. Four patients with bilateral synchronous multiple primary lung cancer underwent staging operation treatment( larger lesions on one side of lung underwent conventional thoraceotomy and lobectomy, and smaller lesions on another side underwent thoracoscopic lobectomy or wedge resection afer 1 month) . For 1 patients with ipsilateral synchronous multiple primary lung cancer, simultaneous operation was performed. There was no death during perioperative period or severe cardiopulmonary complications. They were followed up for 3 years. The survival rate was 80. 0%( 4 /5) at 1 year and 60. 0% ( 3/5) at 3 years, respectively. Conclusions With the development of medical science and awareness of pulmonary multiple primary cancer, early diagnosis improves continuously. Active treatment with operation can achieve better prognosis.
Objective To investigate the diagnosis and treatment methods of primary cardiac malignant tumors，so as to improve its’ level of diagnosis and treatment. Methods From April 2004 to June 2008, 19 patients with primary cardiac malignant tumors were diagnosed and treated in the department of cardiac surgery in this hospital. Male 11, Female 8.Age of the patients was 40.7±12.1 years(17-64 years). Preoperative diagnosis were occupying lesion in cardiac, malignant tumors were possible. Complete resections of malignant tumors were achieved by cardiopulmonary bypass (CPB) in 3 cases, and partially resected in 1 case, heart transplantation was performed in 1 case, only biopsies were performed in 5 cases. 9 cases (47.4%) lost the chances of operative treatments. Results There were no operative and hospitalstay deaths. Hospital stay was 10±7 d（9-15 d）, all patients were safely discharged from hospital. Two cases suffered from postoperative pericardial effusions，and high temperature happened in 1 patient, these 3 cases recovered by puncture and symptomatic treatment. The pathological diagnosis: leiomyosarcoma in 1case, malignant mesothelioma in 1 case and hemangioendothelial sarcoma in 8 cases. 14 cases (73.7%) were followed up from 1 to 38 months, 14 cases died of tumor recurrence or metastasis, the mortality was 73.7%, 5 cases (26.3%) were failed to be followed up. Conclusion The prognosis of patient with primary cardiac malignant tumor is still poor. Earlier diagnosis and complete surgical removal of the tumor as soon as possible may improve the patients’qualities of lives.
In the research process of uveal melanoma (UM), the Collaborative Ocular Melanoma Study (COMS) is a landmark and outstanding clinical study. Its research conclusions are the foundation for today's UM clinical work and guidelines. COMS is the first and largest randomized clinical trials conducted to date, comparing the survival outcomes of two or more treatment regimens for primary malignant intraocular tumors with high reliability. Its research design, methods, and conclusions are still widely cited in this day. Learning from the research experience of COMS, summarizing research data based on Asian populations, and studying treatment methods suitable for Asian UM patients is a powerful supplement to COMS data, but also an expansion of this global research, further improving the level of UM diagnosis and treatment in China.
