Abstract
Background: Transbronchial lung biopsy (TBLB) is an attractive alternative to open lung biopsy as an initial diagnostic procedure for patients with diffuse parenchymal disease or localized densities beyond direct endoscopic vision. TBLB can be carried out safely without fluoroscopy in patients with diffuse lung disease. Since in our bronchoscopic department fluoroscopy is not available, we planned to evaluate the blind (without fluoroscopic guide) TBLB being performed in our department to determine the success rate in obtaining lung tissue, the sensitivity of the procedure and the risk of complications.
Materials and Methods: Sixty-Four TBLB were done in our department during a 6 month period (March-September 1999).
Results: Lung tissue wasn’t detected in two (3.1 percent) samples. Pathological results were helpful in 46 (71.9 percent) cases. No evidence of hemoptysis was found after the procedure. Three (4.68 percent) cases of pneumothorax was detected. Only one of them required chest tube (1.51 percent).
Conclusion: We concluded that blind TBLB was successful in our department with rates of complications comparable to other approved centers.

Abstract
Background: Pulmonary involvement is a common and serious complication of rheumatoid arthritis. This cross sectional study sought to determine the prevalence of pulmonary disease in patients with rheumatoid arthritis on the basis of history, physical examination, chest X-ray and PFT.
Materials and Methods: 103 patients (81 Women, 22 Men) fulfilling the ACR (American College of Rheumatology) criteria for RA (Rheumatoid arthritis) were consecutively included in a cross sectional study. Detailed medical (including respiratory symptoms and the disease activity symptoms) and drug and occupational histories and smoking were obtained. All patients underwent a complete pulmonary and rheumatologic examination and conventional chest radiography. All patients underwent PFT that comprised spirometry and body plethysmography.Results for PFTs were expressed as percentage of predicted values for each individual adjusted for age, sex, and height.
Results: On the basis of history: Their mean age was 43.3 ± 2.6 years (range: 17-74) and the mean duration of the disease was 69.3 ± 15.6 months. Rheumatoid factor was positive in% 61.2. No patients were 0.5Pack/Year smoker in whole life. Prevalence of pulmonary involvement based on radiographic and pulmonary function test detected in 41 patients (39/7%). The most frequent respiratory clinical finding was dyspnea (33%), (NYHA grade I in 17.5% and NYHA grade II in 15.5%), Cough (with or without sputum) in 13.6 %, Crackle was the most sign in pulmonary examination (5.8%). Chest X-ray was abnormal in 13.3 % that the most common finding in this study was reticulonodular pattern in 20 patients (19.4 %), and pleural effusion detected in 7 patients (6.7%). PFT was abnormal in 30 patients (29.1 %). A significant decrease of FEF 25%-75% below 1.64 SD. Small airway involvements was the most abnormal finding of PFT. No relation between rheumatoid arthritis disease activity (ESR>30, Morning stiffness>30', Anemia, thrombocytosis) with pulmonary disease was seen.
Conclusion: This study suggests a high prevalence of lung involvement in patients with rheumatoid arthritis.Therefore we recommend a complete investigation in patients with RA with any respiratory symptom.

Abstract
Background: Hypertention and diabetes are important risk factors for cardiovascular disease. studies have shown that microalbuminuria is a strong predictor of cardiov-ascular disease in different population.In this study the relation of microalbuminuria with diabetes and hypertention as risk factors of atherosclerosis disease were investi-gated.
Methods: Two hundered twenty eight patients with angiographically confirmed coronary atherosclerotic lesions, (mean age 60 ± 0.5 SD) referred to Madani Hospital, Tabriz, Iran were studied .This patients according to the number of diseased vessels were classified in two groups. The levels of glucose and creatinine and that of post parandial glucose were determined in venous blood samples by standard methods. Immunoturbidimetric method was employed in the measurement of microalbuminuria. The results were analysed by statistical tests.
Results: The increased albumin/creatinine ratio was markedly correlated with fasting blood sugar, systolic and diastolic blood pressure (P < 0.05 in all cases). Significant correlation was noticed between microalbuminuria, diabetes according to the extension of the disease lesions (P < 0.05). No relationship was observed between microalbumin-uria, high levels of blood pressure according to the number of diseased vessels (P > 0.05). Conclusion: The relationship between diabetes and microalbuminuria was meaningful. According to atherosclerotic lesions a marked correlation was also noticed between microalbuminuria and diabetes. These facts may contribute to the higher cardiovascular risk in diabetic patients. An associated between hypertension and microalbuminuria was noticed. The result suggests that although risk factors such as hypertension and diabetes are known to cause cardiovascular disease, microalbuminuria may in fact be a better indicator of established microvascular damage and better predictor of cardiov-ascular events.

Abstract
Background: Community-acquired pneumonia could be a life-threatening condition especially in elderly patients. The factors influencing the outcome in elderly patients are thought to be different from those in young adults. We compared the clinical and paraclinical profiles in elderly and nonelderly patients with community-acquired pneumonias.
Methods: In this cross-sectional study, seventy nine patients who were hospitalized with community acquired pneumonia over a period of one year were included. Patients' medical records were reviewed and data related to comorbid conditions, signs and symptoms, laboratory and radiographic findings were gathered using a checklist.
Results: The clinical features, laboratory parameters and complications from pneumonia were almost similar in 41 elderly (group I, age ≥65years) and 38 young (group II, age<65years) subjects. Delirium was seen more in elderly group (p=0.05). The average body temperature and pulse rate were significantly higher in nonelderly group. Sixty one percent of elderly patients and 21% of young patients have Po2 less than 60 (p=0.02). Smoking (29.1%), neurological disturbances (19%), congestive heart failure (15.2%), chronic obstructive pulmonary disease and diabetes mellitus (13.9%) were associated comorbidities in both groups. In non elderly group, immune compromise and IV drug use were more common as underlying comorbid conditions. Two of three mortalities were due to elder patients.
Conclusion: Community acquired pneumonia could have more serious clinical and abnormal laboratory features in the elderly than younger patients. Mortality rate may be higher in older patients. Comorbid conditions are frequently seen in both elderly and nonelderly patients with community acquired pneumonia, but IV drug use and immune compromise are more frequent in nonelderly patients.

Abstract
Background: The insertion of endotracheal tube is essential for most surgical operations, mechanically ventilated patient in ICU wards, During cardiopulmonary resuscitation and so for transport of patients. The aim of this study was determination of airway related distances in Iranian patients.
Methods: In a cross- sectional study during year 2007 in Imam Khomeini university Hospital a total of 75 ASA class I and II patients who were admitted to pulmonary ward evaluated for determination of incisor-vocal cord and incisor- carina distances. The nasal nare- vocal cord distance was determined too.
Results: A total of 71 patients, 45(63%) male and 26(36.6%) female were evaluated. The Incisor-vocal cord distance in males and females was 16.83±0.75mm against 15.04±1.12mm (P=0.03). The difference of nare-vocal cords and Incisor- vocal cord distances was 2-3Cm
Conclusions: There was direct association between height and tracheal length in the study patients. The tracheal length (suitable insertion depth) in our patients was different from the recommendations (23 & 21 Cm for men and women) for non- Iranian, 25.9 versus 22.6 for Iranian men and women respectively. The difference of nasal nare-vocal cord and upper incisor-vocal cord distances in our patients was 2-3 cm, the lower range of accepted or reported one. We offer to do another experience with larger study group to apply the data to Iranian population.

Abstract
Background: 4-Aryl-4H-chromenes are novel anticancer agents which induce apoptosis in cancer cells. These compounds were found to induce apoptosis by targeting the tubulin/microtubule system in cell proliferation process. The aim of this study was to report cyototoxic and apoptosis inducing activities of a new series of synthesized 4-aryl-4H-chromenes compounds.
Methods: The in vitro cytotoxic activity of the synthesized 4-aryl-4H-chromenes was investigated against a paned of human cancer cell lines including MCF-7 (breast carcinoma), A549 (lung carcinoma), HEPG-2 (liver carcinoma), SW-480 (colon adenocarcinoma), U87-MG (glioblastoma), 1321N1 (astrocytoma), and DAOY (medulloblastoma). The percentage of growth inhibitory activity was evaluated using MTT colorimetric assay versus controls not treated with test derivatives. The data for etoposide, a well known anticancer drug, was included for comparison. For each compound, the 50% inhibitory concentration (IC50) were determined. Apoptosis inducing activity were assessed by DAPI staining.
Results: Preliminary screening showed that those chromenes analogs bearing phenyl-isoxazole-3-yl substitution or the derivatives containing methoxyphenyl in chromene ring exhibited cytotoxic and apoptotic inducing activity comparable with or even superior than the reference drug, etoposide. The compounds without this type of substitution have lower activity.
Conclusions: Replacement of 3, 4, 5-trimethoxyphenyl group with thiazol ring in the synthesized derivatives reduced the cytotoxic activity. However, the derivatives with phenyl-isoxazole analogue showed potent cytotoxic and apoptotic inducing activity.

Background: Diffuse large B Cell lymphoma (DLBCL)
is the most common subtype of non-Hogkin lymphoma (NHL).
We performed a retrospective study of patients with de novo DLBCL
treated in the Medical Oncology department of Cancer Institute of Iran, Tehran
to assess the clinicopathologic and immunohistochemistry correlation and
prognosis of the patients.
Methods: World Health Organization
(WHO) classification was used to reexamine 1470
biopsy specimens related to the years 1985-2006.
After excluding five cases of T Cell
large cell lymphoma, 50 Patients diagnosed as
DLBCL.
Results: Median age of the patients was 45.5(20-85)
years: 60% were male and 30%
had primary extranodal disease. The most common extranodal sites were bone,
gastrointestinal tract and Head and neck areas. The most common stages were
stage II (32%), stage III (32%),
stage IV (20%) and stage I
(16%) retrospectively and 33% had B-symptoms.
All of The Patients received chemotherapy (83% CHOP regimen)
and 46% treated by radiotherapy after chemotherapy. With
a mean follow up time of 32 months, median
survival time was 34 (95% CI 24-40) months.
Prognostic factors for survival were tumor stage, B-symptoms
and early relapse (less than 6 months).
Conclusions: Our data showed the importance of Immunohistochemistry method in diagnosis of DLBCL.
Although DLBCL is potentially curable
with CHOP chemotherapy protocol, addition of monoclonal
antibody (Anti CD20) and finding new
prognostic factors to predict early relapse are clearly needed in Iran.

Abstract
Background: Sputum induction has been recently introduced as an effective and inexpensive method for obtaining high quality sputum samples in patients without spontaneous sputum. As all Iranian physicians might not be familiar with this method yet, the results of this study could be of help in this regard.
Methods: During June 2010 to January 2011, all pulmonary tuberculosis (PTB) suspected patients, with clinical and/or radiological evidence in favor of PTB who had been referred to the Pulmonary Diseases department of Imam Khomeini Medical Center were enrolled in the study, if they were without spontaneous sputum. Sputum induction was performed using ultrasound nebulized hypertonic 3% sterile saline for 20 minutes. The laboratory was requested to report if the samples were of the intended quality (Polymorphonuclear Cells/Squamus Epithelial Cells≥2). The patients' demographic data, HIV serology and chest radiological findings in favor of PTB were recorded and analyzed.
Results: In 50 patients with suspected PTB [23 men (mean age (±SD), 51.21±20.24) and 27 women (mean age (±SD) 55.40±18.00)], cough was the most common complaint. The most prevalent radiological findings were infiltration and consolidation. PPD was positive in 21 (42%) patients. Sputum induction led to obtaining proper sputum samples in 90% of the patients. Positive sputum smear and culture were seen in 13 (26%) cases.
Conclusion: Sputum induction is a cost-effective and minimally invasive method which is associated with satisfactory results for obtaining high quality sputum samples in patients without spontaneous sputum.

Abstract
Background: The occlusion of the artery and vein grafts are currently a major problem in coronary bypass surgery. Degradation of collagen and elastin, the most abundant extracellular matrix proteins in the vessel wall by matrix metalloproteinase (MMPs), leads to a rearrangement of the extracellular matrix and vascular wall structure. The present study aimed to compare the histological and biochemical characteristics of arteries and veins which could have a role in the failure of the graft.
Methods: This study was a cross-sectional study of 80 patients conducted at Heart Hospitals in Isfahan, Iran, between July 2012 and November 2013. Samples were collected from the remains of vessels used in bypass surgery of 11 male nondiabetic patients. The histologic, collagen elastin ratio and MMPs levels of the vessels were investigated. MMPs were determined using the Gelatin Zymography method. For elastin and collagen content measurement, the sample was digested by cyanogen bromide and hydrochloric acid and then hydroxyproline was measured with a spectrophotometer.
Results: The amount of active and inactive MMP-2 and MMP-9 of the left internal mammary artery (Lima) was similar to aorta, but the amount of MMP-2 and MMP-9 in the radial artery and saphenous vein were significantly higher than aorta. Elastin to collagen ratio in Lima (1.92±1.15) was similar to the aorta (3.4±1.66), but this proportion in saphenous vein (1.07±0.47) and radial artery (1.14±0.39) was significantly lower in the aorta (P≤0.05). Most patients had atherosclerotic plaque in radial while there was atherosclerotic plaque in Lima of only one case.
Conclusion: The presence of atherosclerotic plaques in radial and thickening of the intimal layer of the saphenous vein in the majority of patients and decrease of collagen to elastin ratio and the high level of matrix metalloproteinase enzymes in the radial and saphenous vein can induce early pathological conditions, and remodeling of the vessels involved. So the results of this study confirm that Left Internal Mammary Artery (LIMA) is the most suitable candidate for bypass surgery.

Abstract
Pleural effusion (PE) is common among ICU and acutely ill patients. Traditionally plain chest radiography (CXR) has been done for pleural effusion evaluation in ICU. However, better results have been reported by ultrasound for the diagnosis of this condition in ICU. In this study, we compared two methods of ultrasound and CXR in PE detection in ICU patients. Also we studied the percentage of thoracentesis by physician after detection of PE by ultrasonography or CXR.
Methods: Portable supine CXR and chest ultrasound were done in Thirty-nine non-surgical patients who were admitted to the Medical and General ICUs of Imam Khomeini hospital in Tehran from Oct 2013 to Mar 2014. Ultrasound was done and interpreted by radiologist and CXR by patient' physician. Thoracentesis or CT-scan was used as gold standard for PE diagnosis.
Results: Ultrasound in 29 patients (74.3%) showed PE. In 21 patients thoracentesis was done by patient’s physician and all had PE with mean volume of 447.2(417.6). In 13 of 18 patients without thoracentesis chest CT scan was available. It shows PE in 6 cases (all with positive PE in ultrasonography). CXR in 9 patients (23.1%) was positive for PE and in 30 patients (76.9%) was negative. The ability of chest ultrasound and CXR for diagnosis of PE was significantly different (P= 0.0.1). In 68.9 % of cases that ultrasound was positive, the CXR was negative and only in 34.5% of cases both methods had negative results. The sensitivity, specificity, positive and negative predictive values were 100% (87.1-100), 100% (58.9-100), 100% (87.1-100), 100% (58.9-100) respectively for ultrasonography. For CXR there were 33% (16.6-54.0), 100% (58.9-100), 100% (66.2-100), 28% (12.1-49.4) respectively.
Conclusion: Ultrasonography for diagnosis of pleural effusion in ICU patients has better diagnostic performance than portable CXR
