Abstract Indonesia as a developing country has air pollution which is mainly caused by motor vehicle emissions and industrial smoke. The most important indoor air pollution is cigarette smoke. The prevalence of smoking among Indonesian men is 45.7%. Of the population, 10.8% are ex-smokers and 43.5% are non-smokers. Among the female population, only 1.8% smoke. There are some important factors that influence the air pollution in Indonesia; this paper identifies the real problems and their impact. The paper reviews various studies that have been carried out in Indonesia which were related to ambient air quality, industrial air pollutants and the respiratory problems resultant. From all available data, it is concluded that the air pollutants levels (SO2 , NOx, Ox, Pb, CO, HC) in large cities in Indonesia have exceeded the acceptable level, especially in industrial trade and heavy traffic areas. The more cigarettes inhaled and the deeper the inhalation, especially the kretek cigarettes, the risk of lung function abnormality becomes greater. Smoking high dose kretek cigarettes, that is ≥ 116 cigarettes/day x years, the risk of abnormal lung function is 13-fold that of a non-smoker; if added with the deep inhalation of smoke, the risk becomes 20-fold. Smoking increases the risk of occupational lung diseases. The level of dust in some industrial areas exceeded the standard level and correlated with respiratory problems. The existence of industry-caused air pollution in the environment increased the incidence of obstructive airway diseases. We conclude that the main cause of air pollution in Indonesia is motor vehicle emissions, followed by industrial smoke. Cigarette smoke is also related to abnormal lung function. 相似文献

The connective tissue diseases (CTDs) are inflammatory, immune-mediated disorders in which interstitial lung disease (ILD) is common and clinically important. Interstitial lung disease may be the first manifestation of a CTD in a previously healthy patient. CTD-associated ILD frequently presents with the gradual onset of cough and dyspnea, although rarely may present with fulminant respiratory failure. Infection and drug reaction should always be ruled out. A diagnosis of idiopathic ILD should never be made without a careful search for subtle evidence of underlying CTD. Treatment of CTD-ILD typically includes corticosteroids and immunosuppressive agents. 相似文献

Simultaneous two-level esophageal 24-hour pH monitoring in patients with mild and severe esophagitis
Antonio Ruiz-De-León PhD MD Dr. Concepción Sevilla-Mantilla PhD MD Julio Pérez-de-la-Serna PhD MD Carlos Taxonera PhD MD Manuel Díaz Rubio PhD MD 《Digestive diseases and sciences》1995,40(7):1423-1427
Simultaneous ambulatory esophageal pH monitoring was performed in 10 patients (group 1) with normal distal acid exposure and in 40 patients (group 2) with pathological distal reflux. The probes were placed 5 and 10 cm above the lower esophageal sphincter to quantify variations of pH values that can be due to a displacement of pH sensor. In group 1 the median percent time with pH<4 for total and upright monitoring periods and composite score were significantly lower at the proximal than the distal level. In group 2 all pH data were significantly lower at the proximal than the distal level. The patients with pathological reflux were subdivided into two subgroups based on endoscopic findings (mild and severe esophagitis). The patients with severe esophagitis showed a proximal acid reduction higher than in patients with mild esophagitis. Nine patients with mild esophagitis showed normal values at 10 cm, but all patients with severe esophagitis had abnormal proximal acid exposure. 相似文献

Pregnancy may affect the diagnosis, management, and outcome of infiltrative lung disease (ILD). Conversely, ILD may affect pregnancy. ILD may occur as a result of drugs administered commonly or specifically during pregnancy. Most ILDs predominate in patients older than 40 years and are thus rare in pregnant women. During pregnancy ILD may arise de novo and preexisting ILD may be exacerbated or significantly worsened. Some ILDs generally do not alter the management of pregnancy, labor, or delivery. Preexisting ILD no longer contraindicates pregnancy systematically, but thorough evaluation of ILD before pregnancy is required to identify potential contraindications and adapt monitoring. 相似文献

Chronic lung diseases represent a significant global burden. Their increasing incidence and complexity render a comprehensive, multidisciplinary and personalized approach to each patient, critically important. Most recently, unique biochemical pathways and disease markers have been identified through large‐scale metabolomic studies. Metabolomics is the study of metabolic pathways and the measurement of unique biomolecules in a living system. Analysing samples from different compartments such as bronchoalveolar lavage fluid (BALF) and plasma has proven useful for the characterization of a number of pathological conditions and offers promise as a clinical tool. For example, several studies using mass spectrometry (MS) have shown alterations in the sphingolipid metabolism of chronic obstructive pulmonary disease (COPD) sufferers. In this article, we present a practical review of the application of metabolomics to the study of chronic lung diseases (CLD): COPD, idiopathic pulmonary fibrosis (IPF) and asthma. The insights, which the analytical strategies employed in metabolomics, have provided to the dissection of the biochemistry of CLD and future clinical biomarkers are explored. 相似文献

Background and objective: Interstitial lung diseases (ILD) are characterized by progressive interstitial pulmonary fibrosis and a decline in lung function. Fibrocytes are bone marrow‐derived mesenchymal progenitor cells that may play a role in the pathogenesis of pulmonary fibrosis. Circulating fibrocyte numbers have been correlated with the prognosis of patients with idiopathic pulmonary fibrosis. The aim of the present study was to evaluate the relationship between circulating fibrocytes, and parameters of disease activity and progression in several groups of patients with ILD. Methods: The study population comprised 41 patients with ILD and seven healthy control subjects. Circulating CD45+ collagen‐I+ fibrocytes were evaluated by flow cytometry. Results: The number of circulating fibrocytes was significantly increased in all patients with ILD and particularly in patients with idiopathic interstitial pneumonitis and interstitial pneumonitis associated with collagen vascular disease as compared with healthy control subjects. The numbers of circulating fibrocytes were significantly correlated with pulmonary function test parameters and with serum levels of sialylated carbohydrate antigen, a marker of disease activity. Temporal changes in circulating fibrocyte numbers were evaluated in two patients, and the results suggested that these changes correlated with the activity of ILD. Conclusions: The results from this study provide further evidence for the role of circulating fibrocytes in fibrotic lung diseases. 相似文献

目的了解与弥漫性结缔组织病相关的肺间质病变(CTD—ILD)的发生率、影像学特征及其与病种和临床指标的相关性。方法回顾分析我院几种弥漫性结缔组织病患者(共412例)资料,X线胸片检查或有肺部临床症状患者作胸部高分辨CT(HRCT)进一步检查确诊。了解ILD在不同弥漫性CTD中的发生率,对比X线与HRCT的差异,统计常用CT分类在本组疾病中的分布比例.探讨CT分类与不同病种或临床特征之间的关系。结果在412例弥漫性结缔组织病中,HRCT诊断的ILD共40例,总发生率为9.7%。其中皮肌炎/多肌炎为25%,硬皮病为23.8%,原发性干燥综合征为9.6%,系统性红斑狼疮为6.3%。胸片与CT符合率40%,胸片误诊漏诊率60%。ILDCT分类以两种病变共存最多见,其中毛玻璃样变占40.1%,实变影32.8%,网格影16.4%,蜂窝状影9.8%。呼吸道症状和补体C3,C4水平在毛玻璃样变组及实变影组;C反应蛋白(CRP)水平在蜂窝状影和实变影组较其他对照组明显高,它们之间差异有统计学意义(P〈0.05)。结论HRCT发现CTD—ILD的敏感性及准确性明显优于X线,其中以毛玻璃及实变影最多见;影像学改变与呼吸道症状及炎症指标有一定关系,尽早进行HRCT的检查有助ILD的早期诊断及预后判断。 相似文献
