原发性干燥综合征合并间质性肺病的临床特征

目的探讨原发性干燥综合征（primary Sjogen’s syndrome,pSS）合并间质性肺病（interstitial lung disease．ILD）的临床及影像学特点,以提高对原发性干燥综合征合并间质性肺病（pSS—ILD）的认识。方法回顾性分析本院2004年1月．2007年12月确诊且资料完整的219例pSS患者,对其中47例合并ILD患者的临床特点及影像学检查进行分析。结果（1）pSS组ILD的发生率为21．46％,pSS-ILD组发病年龄晚于pSS一无ILD组,且病程长于pSS．无ILD组（P〈O．01）;（2）pSS-ILD组血沉（erythroeyte sedimentation rate,ESR）明显增快,C反应蛋白（C-reaetive protein,CRP）明显增高,两者与pSS-无ILD组比较差异均具有统计学意义（P〈0．01）;（3）pSS-ILD组抗SSA抗体阳性率高于pSS-无ILD组（P〈0．05）;抗核抗体（antinuclear antibody,ANA）、类风湿因子（rheumatoid factor。RF）、抗SSB抗体、血浆球蛋白〉30g／L、低补体C3和低补体C4在两组间无明显差异;（4）在诊断pSS—ILD病变时,肺高分辨率CT（high resolution computerized tomography,HRCT）明显优于普通X线胸片。结论ILD是pSS常见的系统损害。pSS-ILD的发生与疾病的活动及某些自身抗体有关,肺HRCT有助于pSS—ILD患者的早期诊断及预后判断。     

原发性干燥综合征相关间质性肺疾病患者血清活性氧、转录因子κB及转化生长因子β_1水平变化及其临床意义研究

目的观察原发性干燥综合征相关间质性肺疾病(pSS-ILD)患者血清活性氧(ROS)、转录因子κB(NF-κB)及转化生长因子β_1(TGF-β_1)水平变化,并探讨其临床意义。方法选取2015年7月—2017年6月宁夏回族自治区人民医院呼吸科和风湿科收治的女性原发性干燥综合征(pSS)患者94例,其中单纯pSS患者46例作为pSS组,pSS-ILD患者48例作为pSS-ILD组;另选取同期体检健康女性50例作为对照组。采用免疫印迹法检测抗干燥综合征A(SSA)抗体、抗干燥综合征B(SSB)抗体、抗Robert52(Ro52)抗体,采用酶联免疫吸附试验(ELISA)检测血清ROS、NF-κB及TGF-β_1水平;血清NF-κB水平与pSS-ILD患者血清ROS及TGF-β_1水平的相关性分析采用Pearson相关性分析。结果 pSS组和pSS-ILD组患者抗SSA抗体、抗SSB抗体及抗Ro52抗体阳性率高于对照组(P<0.05);pSS组和pSS-ILD组患者抗SSA抗体、抗SSB抗体及抗Ro52抗体阳性率比较,差异无统计学意义(P>0.05)。pSS组和pSS-ILD组患者血清ROS、NF-κB及TGF-β_1水平高于对照组,pSS-ILD组患者血清ROS、NF-κB及TGF-β_1水平高于pSS组(P<0.05)。Pearson相关性分析结果显示,血清NF-κB水平与pSS-ILD患者血清ROS(r=0.95)及TGF-β_1(r=0.98)水平呈正相关(P<0.05)。结论 pSS-ILD患者血清ROS、NF-κB及TGF-β_1水平明显升高,且血清NF-κB水平与血清ROS、TGF-β_1水平有关,推测ROS-NF-κB-TGF-β_1信号通路可能与pSS-ILD的发生有关。

以肾损害为首要表现的抗SSA/SSB抗体阴性的原发性干燥综合征1例报告

<正>原发性干燥综合征（primary Sj?gren’s syndrome,pSS）以口眼干燥为主要临床表现,抗SSA/SSB抗体是本病的标志性抗体,多个pSS国际分类标准将抗SSA抗体/抗SSB抗体阳性作为诊断条件之一。然而,当患者抗SSA/SSB抗体阴性,口眼干燥的症状轻微,并同时以突出的肾脏损害为首要表现时,诊断较为困难。现报道1例以肾损害为首要表现的抗SSA/SSB抗体阴性的pSS病例,以期进一步提高临床医生对该病的认识,避免漏诊或误诊。

Is the professional satisfaction of general internists associated with patient satisfaction?

BACKGROUND: The growth of managed care has raised a number of concerns about patient and physician satisfaction. An association between physicians’ professional satisfaction and the satisfaction of their patients could suggest new types of organizational interventions to improve the satisfaction of both. OBJECTIVE: To examine the relation between the satisfaction of general internists and their patients. DESIGN: Cross-sectional surveys of patients and physicians. SETTING: Eleven academically affiliated general internal medicine practices in the greater-Boston area. PARTICIPANTS: A random sample of English-speaking and Spanish-speaking patients (n=2,620) with at least one visit to their physician (n=166) during the preceding year. MEASUREMENTS: Patients’ overall satisfaction with their health care, and their satisfaction with their most recent physician visit. MAIN RESULTS: After adjustment, the patients of physicians who rated themselves to be very or extremely satisfied with their work had higher scores for overall satisfaction with their health care (regression coefficient 2.10; 95% confidence interval 0.73–3.48), and for satisfaction with their most recent physician visit (regression coefficient 1.23; 95% confidence interval 0.26–2.21). In addition, younger patients, those with better overall health status, and those cared for by a physician who worked part-time were significantly more likely to report better satisfaction with both measures. Minority patients and those with managed care insurance also reported lower overal satisfaction. CONCLUSIONS: The patients of physicians who have higher professional satisfaction may themselves be more satisfied with their care. Further research will need to consider factors that may mediate the relation between patient and physician satisfaction.

Clinical and pathological characteristics of patients with pulmonary inflammatory pseudotumors: An 18-year retrospective study of 31 cases

To investigate the clinical and pathological characteristics in patients with pulmonary inflammatory pseudotumors (PIP).This retrospective study included 31 patients with PIP from 2001 to 2019. Preoperative computed tomography scan was performed in all patients. Clinical and pathological characteristics were collected and analyzed.Thirty-one patients (16 female and 15 male) were recruited, with a median age of 57 years (range, 11–72 years). Eight (25.8%) patients were asymptomatic, and the others had symptoms characterized by cough with sputum, chest and back pain, dry cough, fever and blood in sputum, or hemoptysis. All cases were single lesions, including 23 cases in the right lung, and 8 cases in the left lung. Computed tomography scan demonstrated irregular lobulated nodules or masses in 14 patients, and regular round or oval nodules or masses in 11 cases. The blurred edge of tumors and spiculation was found in 12 cases. Microscopic results were characterized by the collection of inflammatory mesenchymal cells. Immunohistochemical examination showed vimentin, smooth muscle actin, and anaplastic lymphoma kinase positive. Complete tumor resection was obtained in all cases. No recurrence or metastasis was observed during the follow-up period.PIP has a variety of manifestations. Preoperative diagnosis is difficult to reach. The final diagnosis still depends on the pathological and immunohistochemical examination. Complete surgical resection is the main treatment at present, and the overall prognosis is good.

Who Joins the BDA?

A comparison of demographic and clinical characteristics was made between a random sample of members and non-members of the British Diabetic Association (BDA) of working age (17-65 years) who responded to a questionnaire concerning their employment. There were large regional variations in BDA membership, but overall 27% of responders were BDA members. Of the responders, BDA members were more likely to be women than men (30 vs 25%, p = 0.04) and under rather than over the age of 36 years (38 vs 21%, p less than 0.001). A greater proportion of insulin-treated patients with diabetes were BDA members compared with patients who were not treated with insulin (37 vs 13%, p less than 0.001). Unemployment was significantly less amongst BDA members compared with non-members (12 vs 20%, p less than 0.001). Membership decreased with decreasing social status, with significantly more house-owners being BDA members compared with those living in rented accommodation (31 vs 23%, p less than 0.001).     

Imaging and pathological characteristics,treatment, and prognosis of pulmonary sequestration—A retrospective study of 13 cases

Objective

This study aimed to summarize and analyze the characteristics of pulmonary sequestration to improve our understanding of this disease.

Methods

Between January 2019 and April 2023, the clinical data of 13 patients with pulmonary sequestration underwent surgical treatment at the First Affiliated Hospital of Gannan Medical University.

Results

The male-to-female ratio was 4:9, the age was 0.5 to 60 years, and the average age was 38 ± 19 years. There were 10 and 3 cases of intralobar and extralobar pulmonary sequestration, respectively. Chest enhanced computed tomography (CT) and three-dimensional vascular reconstruction showed that the abnormal blood vessels were derived from the descending thoracic aorta in nine cases and from other blood vessels in four cases. Three patients underwent thoracoscopic lobectomy, two underwent thoracoscopic segmentectomy, and eight underwent thoracoscopic wedge resection. All the patients successfully completed the surgery and were discharged postoperatively.

Conclusions

Some patients with pulmonary sequestration exhibit no obvious symptoms. Patients with clinical symptoms are easily confused for pneumonia, bronchial cysts, lung abscesses, and lung tumors; therefore, patients with pulmonary sequestration are prone to missed diagnosis and misdiagnosis. Currently, enhanced chest CT combined with three-dimensional vascular reconstruction can accurately show the course, branches, and relationship with the mass of the feeding artery. Routine pathological examination is helpful to further clarify the diagnosis of pulmonary sequestration. Minimally invasive thoracoscopic surgery is the preferred treatment for patients with pulmonary sequestration. Surgical resection is safe and feasible, and satisfactory results are typically obtained.
