脾结核的临床特征

目的 探讨脾结核的临床特点、诊断和治疗。方法 回顾性分析经临床、手术及病理证实的11例脾结核的临床特征。结果 11例患者中，男7例，女4例，平均年龄29岁。6例术后证实，5例经内科保守治疗后证实。多数患者表现为发热、消瘦、血沉增快、贫血、脾肿大，B超发现脾脏肿大11例，其中8例脾内多发占位，3例为孤立性占位；7例行CT检查，6例发现脾脏多发性大小不等的结节状低密度灶，1例为单发类圆形低密度影，边缘不清，增强扫描病灶内部无强化；6例患者伴后腹膜、脾门区等淋巴结肿大，5例患者伴其它脏器结核。结论 不明原因发热、消瘦、血沉增快、贫血、脾肿大为脾结核的主要临床表现，腹部B超和腹部CT能对脾结核作出较准确的判断，脾结核患者经正规治疗可治愈。     

Maturation of Pulmonary Metastases of Wilms' Tumor after Therapy: A Case Report

A case is reported of Wilms' tumor associated with multiple pulmonary metastases histologically showing maturation of the tumor cells at 9 years after the resection of the primary tumor and intensive therapy. A huge tumor of a 22-month-old patient's right kidney was resected. The tumor was diagnosed as Wilms' tumor of mesenchymal type (stage 1), which consisted of predominantly immature mesenchymal tissue including rhabdomyoblasts, smooth muscle and fibrous tissue, and few blastemal and epithelial components. Intensive preoperative and postoperative chemotherapy with actinomycin D and vincristine and postoperative irradiation therapy totaling 16 Gy were carried out. The patient was regularly followed up uneventfully until 9 years after the surgery. On routine chest x ray at the age of 10 years 11 months, multiple pulmonary nodules were found. The excised nodules from the bilateral lungs disclosed similar histology, exclusively composed of dense collagen bundles and fibrocytes intermingled with mature striated muscle bundles. No immature tumor components were detected. The possible effect of intensive therapy in this maturation was stressed, although spontaneous benign differentiation of tumor cells cannot be excluded.     

矽肺患者肺功能与动脉血气分析的研究

本文对88例矽肺病人和37名接尘工人进行了肺功能和动脉血气分析,结果表明各期矽肺的VC、FVC、FEV_1、MMF、FEV_1/FVC均值低于接尘组,而异常检出率则高于接尘组,通气功能的下降呈进行性,但早期不很明显,与接尘组无显著差异。各期矽肺组V_(50)及V_(25)均有明显降低,显示早期即有小气道的广泛损害。矽肺的通气功能损害类型,Ⅰ期矽肺组以阻塞型多见,Ⅱ、Ⅲ期矽肺组以混合型为主。RV和RV/TLC在Ⅲ期矽肺组有明显增高,表明矽肺晚期多并发肺气肿。另外DL_(CD)和K_(CD)在各矽肺组均低于接尘组,差异有显著性,说明矽肺早期即可有弥散功能的损害。血气分析表明PaO_2及SatO_2降低主要见于Ⅱ、Ⅲ期矽肺。Ⅲ期矽肺组有1/3患者(33.33％)在有低氧血症的同时合并有高碳酸血症。对比肺功能和血气分析结果,认为通气功能指标FEV_1、FEV_1/FVC、VC、FVC、MMF以及弥散功能指标DL_(CO)和K_(CO)为早期反映矽肺呼吸功能的灵敏指标。血气分析对病情和预后的判断有重要参考价值。     

慢性阻塞性肺疾病患者家庭支持与自我概念的相关性研究

目的 探讨慢性阻塞性肺疾病(慢阻肺)患者的家庭支持与自我概念的关系。方法 用方便抽样法选取108位慢阻肺患者，应用修订的个人资源问卷、自我概念量表和一般资料问卷分别测定其家庭支持、自我概念水平和一般资料。结果 该组患者家庭支持程度为中到高度，自我概念中度积极；家庭支持与总的自我概念呈中度正相关，与自我概念中的体感、自我一致性、理想自我及道德一伦理一精神自我有显著相关．与体象无关。结论 慢阻肺患者的家庭支持水平越高，其自我概念越积极。     

Unique variant of partial anomalous pulmonary venous connection with intact atrial septum

Summary Partial anomalous pulmonary venous connections (PAPVCs) are rare in association with an intact atrial septum. However, the diagnosis should be considered in patients with otherwise unexplained findings of left-to-right shunt and right heart enlargement. An unusual variant is presented, which we considered unsuitable for operative repair, based on findings at catheterization. Developmental, hemodynamic, and surgical considerations are discussed.     

Tuberculosis in children: a 13-year follow up of 1714 patients in a Belgian home care centre

From May 1970 to September 1983, 1714 children with different forms of primary tuberculosis were referred to the paediatric home care centre (Enfants soignés au Foyer, E.S.F.) of the Brussels University Hospital St.-Pierre. They were subdivided in five groups: asymptomatic (33%), symptomatic (28%), dubious tuberculous infections (35%), high-risk contacts (3%) and unestablished diagnosis (1%). They were aged from 10 days to 19 years, and 82% of them were migrants of low socio-economic level. Fifty percent of the symptomatic infections, mainly pulmonary, appeared in children under 3 years of age. An adult source of contamination was identified in 33% of the case (48% of the symptomatic children). Diagnosis was based on tuberculin screening with a 2IU intradermal test. Gastric aspirates yieldedMycobacterium tuberculosis in 15% of our patients, 11% of them showing resistance to one or more tuberculostatic drugs. Treatment was given to 1359 patients with excellent results. Therapy was shortened during the last 2 years of the study from 12 to 6 months for the asymptomatic patients and from 12 to 9 months for the symptomatic infections. Few complications were observed. Tuberculosis remains a serious cause of morbidity particularly in migrant children. Correct diagnosis and treatment of the disease is very important.     

PULMONARY RESECTION FOR METASTATIC BREAST CANCER

Background : A patient with a solitary pulmonary metastasis who had breast cancer in the past may benefit from pulmonary resection. Methods : Between 1984 and 1996, 17 patients underwent metastatectomy for metastatic breast cancer. There were 15 females and two males whose average age was 59 (range: 40–74 years). The median tumour-free interval after the primary breast-cancer operation was 5.1 years (range: 8 months-18.2 years). Sixteen patients had complete resections, which included six lobectomies and 10 lesser resections. Results : The postoperative mortality was nil and the morbidity rate was 6%. Follow-up was complete in all patients. Recurrent disease developed in four patients and two patients died of their disease. The 5-year survival was 62%. Conclusion : An aggressive surgical approach is warranted in patients with isolated resectable pulmonary metastases from breast cancer.     

Postoperative pulmonary complication rate and long-term changes in respiratory function following esophagectomy with esophagogastrostomy

Upper abdominal surgery has a high incidence of postoperative respiratory complications. Although operations involving a thoracic as well as an upper abdominal incision as encountered in esophageal surgery are likely to be associated with an even higher complication rate and perhaps permanent alterations of respiratory function, only a few studies have addressed this problem. We evaluated the postoperative course of patients undergoing thoracoabdominal esophagectomy with esophagogastrostomy. Twenty patients were evaluated, of whom 10 (50%) developed respiratory complications as defined by our criteria, which were the simultaneous occurrence of rectal temperature over 38 degrees C on the first postoperative day and radiographic evidence of pulmonary infiltration. Although there is no general consensus regarding the diagnostic criteria of a postoperative pulmonary complication, we were able to validate the clinical relevance of our definition by showing that these patients suffered from a more severe and more prolonged impairment of global oxygen exchange than those who did not fulfill the criteria. They also required a longer period of respiratory support (median duration of intubation 12 vs. 3 days, P less than 0.005). A comparison of the preoperative pulmonary function with that determined at least 6 months after the operation showed that only vital capacity (VC) and total lung capacity (TLC) were significantly (P less than 0.05) reduced following the operation, but not to a clinically relevant degree (VC-6%, TLC-7%).     

慢性肺心病并发多器官衰竭（附70例报告）

１９８６～１９９２年我院共收治急性发作期慢性肺心病１９６例，其中因严重肺部感染发生多器官衰竭（ＭＯＦ）者７０例（３５．７％），平均受损脏器２．５个，死亡２６例，总病死率为３７．１％。其中２和３个脏器受损者的病死率分别为２０．１％和４４．４％，而４和５个脏器受损者则均死亡。血气分析显示ｐＨ和ＰａＯ２值与受损脏器数目呈负相关，而ＰａＣＯ２值与受损脏器数目呈正相关。本文讨论了肺心病因肺部感染并发ＭＯＦ的发病机理，并提出防治的措施。
