Structural Characteristics of the Iranians Nose: An Anatomical Analysis.

Introduction: Rhinoplasty is one of the most common surgical procedures performed among Iranians. An important issue to be considered by nasal surgeons is anatomical variations between different ethnic groups. Working on Iranians with the existing ethnic variety encourages the need for an analysis of this particular population.

The diagnostic accuracy of endobronchial ultrasound and spiral chest computed tomography scan in the prediction of infiltrating and non-infiltrating lymph nodes in patients undergoing endobronchial ultrasound.

Purpose: Endobronchial ultrasound (EBUS) and spiral chest computed tomography (CT) scan are important methods in the prediction of infiltrating and non-infiltrating lymph nodes, and the determination of their diagnostic accuracy would result in a reduction of the burden of problems and an improvement in prognosis. The purpose in this study was to determine the diagnostic accuracy of endobronchial ultrasound and spiral chest CT scan in the prediction of infiltrating and non-infiltrating lymph nodes in patients undergoing endobronchial ultrasound.

Material And Methods: In this observational prospective study, 40 consecutive patients with infiltrating and non-infiltrating lymph nodes in Masih-Daneshvari Hospital in 2017 and 2018 were enrolled, and the sensitivity, specificity, and accuracy of EBUS and CT-scan versus fine needle aspiration pathology results were determined in them.

Diagnostic triad of pulmonary anthracofibrosis in spiral CT scan - a retrospective study.

Purpose: Anthracosis, a form of pneumoconiosis commonly caused by air pollution and other environmental factors, is a new entity in respiratory disorders. Bronchoscopy and transbronchial lung biopsy (TBLB) are the gold standard of diagnosis. Herein, we evaluated the results of bronchoscopy and chest computed tomography (CT) scans of 187 anthracotic patients.

Radio-pathological correlation of organizing pneumonia (OP): a pictorial review.

Since the description of cryptogenic organizing pneumonia in 1983 by Davison et al and the subsequent report on bronchiolitis obliterans organizing pneumonia by Epler et al, some reports have been published regarding the imaging features of organizing pneumonia (OP). In this pictorial review, we aimed to describe and illustrate different manifestations of OP on high-resolution CT (HRCT) accompanied by their histopathological correlations for a better comprehension of pathomechanism of the radiological findings. The main HRCT findings in OP include: consolidation, ground-glass opacification, perilobular opacity, reversed halo opacity, nodule or mass, parenchymal bands, bronchial wall thickening, bronchial dilatation, mediastinal lymphadenopathy and pleural effusion.

What Do We Know about Anthracofibrosis? A Literature Review.

Recently, the significance of anthracosis in the tracheobronchial tree, lung parenchyma, and even non-respiratory organs has been postulated and discussed in association with other diseases, especially tuberculosis. We reviewed the current literature by using the following key words in Medline/PubMed, Embase, and Google Scholar databases: anthracosis, anthracofibrosis, anthracotic bronchitis, biomass fuels, and mixed-dust pneumoconiosis. The bibliographies of eligible papers were also reviewed for further relevant articles.

Serum ACE Level in Sarcoidosis Patients with Typical and Atypical HRCT Manifestation.

Background: Sarcoidosis is an inflammatory disease that affects multiple organs. Before widespread use of computed tomography (CT), the severity of sarcoidosis was assessed based on chest X-ray abnormalities. HRCT can distinguish between active inflammatory changes and irreversible fibrosis.

Radiologic manifestations of pulmonary tuberculosis in patients of intensive care units.

Background: Tuberculosis (TB) is a serpent disease with various pulmonary manifestations, and timely diagnosis of the disease is paramount, since delayed treatment is associated with severe morbidity, particularly in intensive care units (ICU). Therefore, it is imperative that intensivists understand the typical distribution, patterns, and imaging manifestations of TB.

Aim: To describe different manifestations of pulmonary TB in patients in the ICU.

Massive hemoptysis, a presentation of invasion of aneurysm of descending aorta to bronchopulmonary tree.

Aortobronchial (AB) fistula is a rare disease, which is presented with massive hemoptysis; lethal if not treated. It should be suspected in any patient who presents with massive hemoptysis and had previous thoracic aortic surgery, but even it may be seen in patients without any history of operation on the thoracic aorta. Although, today in many centers endovascular therapy is done for these patients, but it is not the standard approach.

Imaging Findings of Isolated Bronchial Anthracofibrosis: A Computed Tomography Analysis of Patients With Bronchoscopic and Histologic Confirmation.

Background: To evaluate the chest computed tomography (CT) findings of patients with isolated bronchial anthracofibrosis confirmed by bronchoscopy and histopathology.

Methodology: Fifty-eight patients with isolated bronchial anthracofibrosis (29 females; mean age, 70 years) were enrolled in this study. The diagnosis of bronchial anthracofibrosis was made based on both bronchoscopy and pathology findings in all patients.

Nonspecific Interstitial pneumonia (NSIP)/ Overlap or Distinct Entity: A case report from the National Research Institute of Tuberculosis and Lung Disease (NRITLD).

Background: In many cases of ILD (interstitial lung disease), overlap diagnosis is considered. Here, a few cases with diagnosis of a variety of ILDs, where eventual open lung biopsy has been performed are selected. Reference will be made to reliable sources to show that NSIP can still be a variant of UIP (Usual interstitial pneumonia) with better treatment response and prognosis.

Multidrug resistant tuberculosis versus non-tuberculous mycobacterial infections: a CT-scan challenge.

Introduction: Clinical, laboratory and imaging findings in patients with multidrug resistant-tuberculosis (MDR-TB) and non-tuberculosis mycobacterium (NTM) are similar, and the majority of these patients present with positive smear for Acid Fast Bacilli (ADB) and no response to first line anti-TB treatment, so sputum culture and PCR are necessary, especially in NTM.

Objective: In this study we evaluate more details of imaging findings to help earlier diagnosis of pathogens.

Materials And Methods: 66 patients with positive smear for AFB and no response to first line anti-TB drugs were divided into two groups by PCR and culture: MDR-TB (43 patients) and NTM (23 patients).

Uremic pleuritis in chronic hemodialysis patients.

Chronic hemodialysis (HD) patients are predisposed to several complications associated with pleural effusion. In addition, uremia can directly cause pleuritis. However, there are inadequate data about pathogenesis and natural course of uremic pleuritis.

The correlation of brody high resolution computed tomography scoring system with clinical status and pulmonary function test in patients with cystic fibrosis.

Background: To reduce the mortality and morbidity rates of cystic fibrosis (CF) patients, and to have an effective clinical management, it is important to monitor the progression of the disease. The aim of this study was to evaluate the progression of lung disease in CF patients by means of assessing the correlation of the CT scoring system with clinical status and pulmonary function test at the Pediatric Pulmonary Ward of Masih Daneshvari Hospital in 2008.

Methods: Pulmonary high resolution computed tomography (HRCT) was performed in 23 CF patients using the Brody's scoring system.

Anomalous unilateral single pulmonary vein mimicking pulmonary nodules on HRCT of the lungs and scimitar syndrome on chest radiograph: multidetector CT findings.

Anomalous unilateral single pulmonary vein is an extremely rare anomaly of the pulmonary venous system. It is often confused with other pulmonary abnormalities such as hypogenetic lung (scimitar) syndrome, pulmonary varices, pulmonary nodules, and arteriovenous malformations. We present imaging findings including multidetector computerized tomography in a case of anomalous unilateral single pulmonary vein mimicking pulmonary nodules on high-resolution computed tomography of the lungs and scimitar syndrome on chest radiograph in an asthmatic girl.
