Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.

It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.
Methods which attempt to express in replicable terms the extent of the neoplasm in the patient.
A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Ki-1 (CD30)-positive anaplastic large cell lymphoma, sarcomatoid variant accompanied by spontaneously regressing lymphadenopathy. (1/412)

Although it has been reported that primary Ki-1 (CD30)-positive anaplastic large cell lymphoma (ALCL) of the skin may undergo spontaneous regression, it is rare for ALCL without cutaneous involvement to have spontaneously regressing lymphadenopathy. We report a case of sarcomatoid variant of ALCL accompanied by spontaneously regressing lymphadenopathy. The patient had gastric and pulmonary involvement of ALCL in addition to systemic lymphadenopathy, but with no cutaneous involvement. The lymphadenopathy spontaneously improved gradually during a period of one month without any treatment. At the same time, multiple small nodules in both lung fields decreased on chest computed tomography and multiple elevated gastric tumors with dimples were endoscopically recognized to have improved. He has since been treated with combination chemotherapy because of recurrence of the lymphadenopathy.  (+info)

Mediastinal lymph node metastasis model by orthotopic intrapulmonary implantation of Lewis lung carcinoma cells in mice. (2/412)

This study is designed to establish a pulmonary tumour model to investigate the biology and therapy of lung cancer in mice. Current methods for forming a solitary intrapulmonary nodule and subsequent metastasis to mediastinal lymph nodes are not well defined. Lewis lung carcinoma (LLC) cell suspensions were orthotopically introduced into the lung parenchyma of C57/BL6 mice via a limited skin incision without thoracotomy followed by direct puncture through the intercostal space. The implantation process was performed within approximately 50 s per mouse, and the operative mortality was less than 5%. Single pulmonary nodules developed at the implanted site in 93% of animals and subsequent mediastinal lymph node metastasis was observed in all mice that formed a lung nodule after intrapulmonary implantation. The size of tumour nodule and the weight of mediastinal lymph node increased in a time-dependent manner. The mean survival time of mice implanted successfully with LLC cells was 21+/-2 days (range 19-24 days). Histopathological analysis revealed that no metastatic tumour was detectable in the mediastinal lymph nodes on day 11, but metastatic foci at mediastinal lymph nodes were clearly observed on days 17 and 21 after implantation. Other metastases in distant organs or lymph nodes were not observed at 21 days after the implantation. Comparative studies with intrapleural and intravenous injections of LLC cells suggest that the mediastinal lymph node metastasis by intrapulmonary implantation is due to the release of tumour cells from the primary nodule, and not due to extrapulmonary leakage of cells. An intravenous administration of cis-diamine dichloro platinum on day 1 after tumour implantation tended to suppress the primary tumour nodule and significantly inhibited lymph node metastasis. Thus, a solitary pulmonary tumour nodule model with lymph node metastasis approximates clinical lung cancer and may provide a useful basis for lung cancer research.  (+info)

Bilateral hemothorax revealing mediastinal parathyroid adenoma. (3/412)

We report the case of a 63-year-old woman admitted to hospital because of bilateral hemothorax associated with acute respiratory failure and laterotracheal neoformation. A right thoracoscopy biopsy revealed a paratracheal parathyroid adenoma which was responsible for bilateral hemothorax and primary hyperparathyroidism. A curative resection was successfully performed by cervicotomy.  (+info)

Contamination of lymph from the major prenodal cardiac lymphatic in dogs. (4/412)

Cannulation of the canine major prenodal cardiac lymphatic (MPCL) is the most common approach for the investigation of myocardial lymphatic function. However, the assumption that the MPCL drains pure cardiac lymph has been questioned. We studied variations of MPCL anatomy and investigated whether noncardiac lymph is drained by this lymphatic. After dye was injected into the lungs and left ventricular myocardium in 21 dogs, dissection of the cardiac lymphatic system yielded 3 anatomic variations. In variations 1 and 2 (81% of dogs), a mixture of cardiac and pulmonary lymph was drained via the MPCL. In variation 3 (19% of dogs) no connection was found between MPCL and pulmonary lymphatics. In variations 1 and 2, alteration of tidal volume resulted in significant changes of lymph flow rate. The pulmonary contribution to MPCL lymph flow was estimated as 34% in variation 2. We conclude that MPCL lymph may contain not only cardiac lymph but also significant pulmonary contamination. This finding should be considered in the interpretation of lymph data from cannulation of the canine MPCL.  (+info)

How the lymph node metastases toward cervico-upper mediastinal region affect the outcome of patients with carcinoma of the thoracic esophagus. (5/412)

BACKGROUND: The aim of this study was to establish whether the site of lymph node metastasis influences the survival of patients with carcinoma of the thoracic esophagus. METHODS: A series of 159 patients with lymph node metastasis who underwent right transthoracic R0 esophagectomy was analyzed retrospectively. Sites of the nodal metastasis were divided into two regions; the neck and/or upper mediastinum above (upward metastasis) and the abdomen and/or lower mediastinum below (downward metastasis) the tracheal carina. RESULTS: Univariate analysis of prognostic factors revealed the tumor location, distant lymphatic metastasis, number of metastatic nodes and upward metastasis influenced survival, but downward metastasis did not. Multivariate analysis showed that the number of metastatic nodes and upward metastasis were also significant prognostic factors. Thirty-one (33.3%) of the 93 patients with, but only 6 (9.1%) without, upward metastasis had recurrences in the neck and/or upper mediastinum (P = 0.0002). Eighteen (60.0%) of the 30 patients with extranodal invasion in the neck and/or upper mediastinum had recurrence in these regions. CONCLUSIONS: Nodal metastasis in the neck and/or upper mediastinum was a significant risk factor for prognosis, the same as the number of metastatic nodes.  (+info)

Core needle biopsy is effective in the initial diagnosis of mediastinal lymphoma. (6/412)

BACKGROUND AND OBJECTIVE: With the development and refinement of guidance modalities for percutaneous biopsies, many investigators have reported studies supporting the role of guided core needle biopsy in the diagnosis of mediastinal lymphoma. The aims of this report are to evaluate the efficacy of findings at core needle biopsy of mediastinal masses on patient care and define the key determinants of clinical success. DESIGN AND METHODS: Fluoroscopy-guided (in 75 patients) and computed tomography-guided (in 8 patients) core needle biopsies were performed in 83 patients with mediastinal lymphoma: all but one of the patients were at first diagnosis. All the biopsies were performed using a Menghini needle (from 1.2 mm to 1.8 mm). In the vast majority of cases the 1.8 mm gauge was employed. RESULTS: The overall sensitivity for the diagnosis of lymphoma was 81% (67/83 cases). In the remaining 16 patients the lymphoma diagnosis was reached either by mediastinoscopy (11 cases) or anterior mediastinotomy (3 cases) or core needle biopsy of the lung (1 case); one patient was treated directly after the needle biopsy had been unsuccessful because he needed rapid therapy. In 77/82 (93%) patients it was possible to assess the specific histotype. There was no operative mortality; all the biopsies were performed on an outpatient basis. INTERPRETATION AND CONCLUSIONS: Our data indicate that core needle biopsy should be considered as an effective and safe procedure in the diagnosis of patients with mediastinal lymphoma with the possibility of determining the tumor subtype and subsequent specific treatment.  (+info)

Sympathetic reinnervation of cardiac allografts evaluated by 123I-MIBG imaging. (7/412)

Some heart-transplant patients present with improved heart rate response to exercise and anginal pain suggesting reinnervation of allografts. Studies performed up to 5 y post-transplantation have suggested that reinnervation is a slow process that occurs only after 1 y post-transplantation. The purpose of this study was to evaluate the extent of sympathetic reinnervation in heart-transplant patients and its relation to cardiac function. METHODS: We performed 123I-metaiodobenzylguanidine (MIBG) studies and rest/exercise radionuclide ventriculography in 31 heart-transplant patients 6 mo to 12 y post-transplantation. Intensity of myocardial MIBG uptake was quantified by a heart-to-mediastinum ratio (HMR), and the regional distribution of MIBG was determined by tomographic studies. RESULTS: HMR correlated positively with time after transplantation (r = 0.607, P < 0.001). Patients studied from 2 to 12 y post-transplantation had an HMR significantly higher than patients studied before 2 y post-transplantation (1.62 +/- 0.2 versus 1.34 +/- 0.2, P < 0.05). Myocardial MIBG uptake was anterolateral in 16 patients, anterior in 3 and anterolateral and septal in 3. Myocardial MIBG uptake was absent in 9 patients. Vasculopathy developed in 8 patients, and 5 of them (63%) had decreased myocardial MIBG uptake. Peak filling rate was higher in patients studied from 2 to 12 y post-transplantation (2.7 +/- 0.8 end-diastolic volume (EDV)/s versus 2.16 +/- 0.5 EDV/s, P = 0.02). CONCLUSION: Sympathetic reinnervation increases with time after heart transplantation and is seen more frequently after 2 y post-transplantation. Complete reinnervation of the transplanted heart does not occur even up to 12 y post-transplantation. Early vasculopathy may delay the process of sympathetic reinnervation.  (+info)

Left recurrent laryngeal nerve palsy associated with silicosis. (8/412)

Left recurrent laryngeal nerve palsy usually results from invasion or compression of the nerve caused by diseases localized within the aortopulmonary window. This study reports the case of a 76-yr-old male with vocal cord paralysis due to lymph node involvement by silicosis. This rare entity was identified by video-mediastinoscopy, which revealed a granulomatous and fibrosed recurrent lymph node encasing the nerve. The nerve was dissected and released from scar tissues. Progressive clinical improvement was observed followed by total and durable recovery of the voice after 15 weeks follow-up.  (+info)

TY - JOUR. T1 - False-positive CT and Thallium-201 SPECT Results in a Patient with Suspected Lung Cancer and Mediastinal Lymph Node Metastasis. AU - Nakahara, Tadaki. AU - Togawa, Takashi. AU - Suzuki, Aya. AU - Yui, Nobuharu. AU - Kubo, Atsushi. PY - 2003/11/1. Y1 - 2003/11/1. N2 - We describe a patient with a final diagnosis of inflammatory change in which combined imaging results were strongly suggestive of lung cancer with mediastinal lymph node metastases. The patient, who was suspected of having a pulmonary lesion on chest radiography performed at a local hospital, was referred to our hospital. Contrast-enhanced computed tomography (CT) of the chest showed a small-sized opacity in the left upper lung and multiple mediastinal nodules. The largest mediastinal nodule, depicted at a pretracheal region, was 22 mm in size. Thallium-201 single photon emission computed tomography (SPECT) showed increased uptake in these lesions, which exhibited no remarkable washout of the tracer, supportive of ...
Results These 93 patients were referred from 12 hospitals and 20 had undergone previous undiagnostic procedures (6 EBUS, 14 bronchoscopy). The mean age was 67 years (range 27 - 87) and 50 were male. 82 were performed under local anaesthesia using lignocaine spray and intravenous midazolam (1 - 10 mg; mean 4 mgs) and the remaining 11 under general anaesthesia. 200 lymph nodes (2R, 4R, 4L, 7, 10R, 10L, 11R) and 13 lung lesions were biopsied. Results were as follows: Adequate samples were obtained in 99% (91/93) and the NSCLC - NOS rate was 2%. 31 adenocarcinoma, 10 squamous cell carcinoma, 10 small cell carcinoma, 1 NSCLC - NOS, 1 large cell neuroendocrine carcinoma, 1 soft tissue lesion (repeat EBUS showed myxoid spindle cell mesenchymal lesion), 1 breast carcinoma, 19 nonspecific benign nodes, 15 sarcoid and 2 TB. There were no complications. ...
Purpose: Anaplastic lymphoma kinase (ALK) fusion genes represent novel oncogenes for non-small cell lung cancers (NSCLC). Several ALK inhibitors have been developed, and are now being evaluated in ALK-positive NSCLC. The feasibility of detecting ALK fusion genes in samples obtained by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was determined. The clinicopathologic characteristics of ALK-positive lung cancer were also analyzed.. Experimental Design: From April 2008 to July 2009, NSCLC cases with hilar/mediastinal lymph node metastases detected by EBUS-TBNA were enrolled. Positive expression of ALK fusion protein was determined using immunohistochemistry, and ALK gene rearrangements were further examined to verify the translocation between ALK and partner genes using fluorescent in situ hybridization and reverse transcription-PCR. Direct sequencing of PCR products was performed to identify ALK fusion variants.. Results: One hundred and nine cases were eligible for ...
Applicant: Andrea Blueschke Aim of this clinic observational prospective study was to asses the value of endoscopic ultrasonography for mediastinal lymph node staging in non small cell lung cancer, compared with computed tomography. Between 01/01/94 and 30/04/96 85 patients with suspected resectable non-small cell lung cancer underwent endoscopic ultrasonography and computed tomography before resection of tumor. Results of these investigations were compared with histopathological findings. 30 Patients were excluded because of histologically prooven small-cell lung cancer, benign or primary non-bronchial carcinomas. The remaining 55 patients underwent curative tumor resection and systematic mediastinal lymph node dissection. On average per patient 12 lymph nodes were removed and histologically assessed. All lymph nodes were classified according to the Naruke-scheme. For N-Staging a sensitivity of 55. 0% , a specifity of 38.2% and an accuracy of 43.6% were achieved with endoscopic ultrasonography. ...

Patient J.P. (date of birth 04/01/69) was diagnosed in October 2005. A wide excision with 2-cm safety margins was carried out. The left axillary sentinel lymph node biopsy (SLNB) was negative and computed tomography (CT) showed no metastasis. Peginterferon α-2b was administered at a dose of 3 μg/kg/week s.c. from December 2005 to September 2006. In August/September 2006, suspected pulmonary and mediastinal lymph node metastases identified on a thoracic CT scan were confirmed by thoracotomy and pulmonary biopsy. From September 2006 onwards the patient received numerous courses of polychemotherapy (DTIC, cisplatin and vindesine on days 1 and 8) achieving a partial response on the CT scan. In May 2007, there was no evidence of mediastinal lymph node metastasis or residual lung metastasis by CT; PET indicated that lung metastases were inactive. In September 2007, progression of the residual lung metastasis and suspected hepatic metastases (segment 8) was noted and confirmed by excision 2 months ...

The esophagus presents an excellent window for visualization of surrounding structures in the mediastinum. present nomenclature divides the mediastinum into three parts: the upper section (upper esophageal sphincter to aortic arch), middle (aortic arch to subcarinal region, just distal to the azy-gos vein), and lower (subcarinal region to cardia). Figure 3 demonstrates paraesophageal structures and organs. The trachea is seen only as an air column; thus its wall cannot be delineated. Lymph nodes may be visible along the length of the esophagus, even in normal individuals. They may be especially pronounced in the subcarinal region. peri-aortic tissue is seen alongside the distal esophagus.. Lymph nodes can be identified in the posterior mediastinum, retroperitoneum, and celiac regions. posterior mediastinal lymph nodes are predominantly left-sided and communicate with the para-aortic lymph nodes of the abdomen; hence thorough evaluation of the celiac region is important. Additionally, metastases ...

The mediastinum is the anatomic region medial to the pleural sacs between the sternum, vertebral column, rib 1, and the diaphragm. The mediastinum is further divided into inferior and superior parts by a horizontal plane passing through the sternal angle to the T4-T5 intervertebral disc (Figure 5-1A). The inferior mediastinum is classically subdivided into anterior, middle, and posterior parts. Therefore, the four subregions of the mediastinum are as follows: ...
Introduction: Elastography has been proposed for quantitative imaging of strain and elastic modulus distributions in soft tissues. This method generates a strain profile through external tissue compression from the ultrasound transducer.. It has been shown to increase the sensitivity and specificity of FNA for the detection of malignancy. Recently, it has become possible to perform elastographic measurements via an EBUS-bronchosope. It is unclear whether this technique is able to increase the accuracy of EBUS-FNA of mediastinal lymph nodes by a better guidance of the puncture sites. The aim of this study is to check whether elastography using the new ultrasound processor is feasible within a clinical routine and whether it could improve the accuracy of mediastinal lymph node sampling in patients with malignancies.. Method: Elastography was performed in 14 patients with 29 lymph node stations qualitatively (pattern) and quantitatively (strain ratio). All bronchoscopies were done in conscious ...

PY - 2010. Y1 - 2010. N2 - BACKGROUND: Conventional transbronchial needle aspiration (TBNA) is a cheap, minimally invasive tool for lung cancer staging and diagnosis. Endobronchial ultrasound-guided TBNA (EBUS-TBNA) is more sensitive but is more expensive and less widely available. We describe a prospective analysis of TBNA diagnostic, staging and cost utility in a centre in the UK. Objectives: To illustrate the potential diagnostic, staging and cost utility of a low cost conventional TBNA service. METHODS: A prospective analysis of 79 TBNA procedures over a 2-year period was performed looking at performance and cost utility in a mixed cohort with variable pre-test probability of malignancy (year 1) followed by a high probability cohort (year 2). RESULTS: TBNA avoided mediastinoscopy in 25% of the ...

Accurate diagnosis of enlarged hilar/mediastinal lymph nodes is mandatory for adequate management of patients with known primary malignancy. We aimed to determine the sensitivity,specificity,accuracy of EBUS-TBNA for clarification of the nature of enlarged hilar/mediastinal lymph nodes in patients with known extrathoracic malignancy. Patients with extrathoracic malignancy who had undergone EBUS-TBNA for assessment of enlarged hilar/mediastinal lymph nodes in December 2008-September 2011 were reviewed. 48 patients who underwent EBUS-TBNA were included. Mean age of 12 male,36 female patients was 57.38 ±11.60. Malignancy was detected in 18(37.5 %),tuberculosis in 6(12.5%),sarcoidosis in 4(8.3%),anthracosis in 2(4.2%),reactive adenitis in 18(37.5%). EBUS-TBNA was also found to offer an effective accurate and minimally invasive strategy for evaluating nonmalignant lesions of pathological hilar and mediastinal lymph nodes such as tuberculosis and sarcoidosis.

A mediastinoscopy is a surgical procedure performed to examine the mediastinum. The mediastinum is the space behind the sternum (breastbone) in the middle of the chest that separates the two lungs. It contains lymph nodes, the heart and its great vessels, the trachea, the esophagus, and the thymus gland.. The mediastinum can be visualized by the use of an endoscopic instrument called a mediastinoscope. A mediastinoscope is a lighted, long, thin, flexible tube that can visualize the organs and structures of the mediastinum. It also has the capacity to transmit images onto a TV-like monitor.. The procedure is performed in an operating room under general anesthesia. The surgeon makes a small incision in the neck above the top of the sternum and inserts the mediastinoscope. In addition to directly visualizing the mediastinum, tissue samples of mediastinal lymph nodes may be obtained. These lymph nodes receive lymphatic drainage from the lungs. A biopsy of these lymph nodes helps to identify disease ...

All patients with lung cancer may have mediastinal metastases. Although PET scans are quite sensitive for identifying mediastinal metastases, they remain less accurate than mediastinoscopy (see Chapter 70). Preoperative mediastinoscopy is indicated for all patients with a PET scan-positive mediastinum and should be considered for certain patients with a PET scan-negative mediastinum (i.e., those with enlarged nodes on CT scan or with hilar lesions). Although the PET scan remains useful for ruling out distant metastases, it should not be the only study performed to evaluate the mediastinum. Many patients have been denied resection because their PET scan was positive in the mediastinum, only to find a more knowledgeable physician who, on mediastinoscopy, diagnosed mediastinal granulomatous disease instead and then successfully resected the patients stage I cancer (Table 71-1). ...

We report the case of 20-year-old man with a history of Ewings sarcoma in the left humerus diagnosed at the age of 15, who has been in medical oncological follow-up since then. After the diagnosis, he received 5 cycles of neoadjuvant VAC/ifosfamide-VP-16, followed by radical surgery, resulting in pathological complete response according to pathology reports. The patient completed 12 adjuvant cycles of the same regimen and proceeded to regular monitoring. After 2 years free of disease, he received a diagnosis of probable pleuro-pulmonary relapse on a PET-CT, which showed hypermetabolic foci in the oblique fissure of the right lung and in the right subcarinal and hilar lymph nodes, although the latter were described as probably of a non-specific inflammatory nature, and close monitoring with imaging techniques was recommended. No known drug allergies. No toxic habits or occupational exposure. Student; no significant family history. He was referred by the medical oncology department to the ...
Mediastinal fat necrosis (MFN) or epipericardial fat necrosis, as it is commonly referred to in the literature, is a rare self-limiting cause of chest pain of unclear etiology. MFN affects previously healthy individuals who present with acute pleuritic chest pain. Characteristic computed tomography (CT) findings include a fat attenuation lesion with intrinsic and surrounding increased attenuation stranding. There is often associated thickening of the adjacent pericardium and/or pleural effusions. We present two cases of MFN manifesting as ovoid fat attenuation lesions demarcated by a soft tissue attenuation rim with intrinsic and surrounding soft tissue attenuation stranding and review the clinical and pathologic features of these lesions. Knowledge of the clinical presentation of patients with MFN and familiarity with the characteristic imaging findings of these lesions should allow radiologists to prospectively establish the correct diagnosis and suggest conservative management and follow-up.
When you perform EUS-FNA of the mediastinal lymph nodes, the points where an approach from the esophagus is possible include both lateral sides and the posterior side of the trachea, as well as the lymph nodes in the inferior mediastinum (Fig.). Both imaging and puncturing of the lymph nodes in front of the trachea are difficult to perform transesophageally. Only the hilar lymph nodes around the main bronchi near the tracheal bifurcations can be approached. However, in endobronchial ultrasonography (EBUS) performed in the respiratory field, you can approach the anterior surface of the trachea and even the hilar and intrapulmonary lymph nodes. The inferior mediastinum, on the other hand, cannot be approached. Puncturing the region sandwiched by the aortic arch and right pulmonary artery (AP window) is also considered difficult. ...
Thymus develops from the ventral portion of the third and fourth pharyngeal pouches. This descends into the anterior mediastinum by the sixth week of gestation. Thymic ectopia results from failure of this migration. Aberrant nodules of thymic tissue are found in approximately 20% of humans. Although the majority of aberrant nodules are located laterally in the neck, ectopic thymic nodules also have been reported in the base of the skull, in the mediastinum, and at the root of the bronchus (1).. Thymic neoplasm arising from an ectopic thymus is rare. To the best of our knowledge, only one case has been reported in the English language literature regarding the imaging findings of the malignant ectopic thymoma (2). In that case, it arose from the posterior mediastinum and had a connecting pedicle between the extrapleural mass and mediastinum. In contrast, the lesion in our case was far from the mediastinum and the results of CT of the chest were normal.. Malignant thymoma is classified into two ...

Despite tuberculosis resurgence and extensive dendritic cell (DC) research, there are no in vivo studies evaluating DC within regional lymphoid tissue during airways infection with virulent Mycobacterium tuberculosis (Mtb) H37Rv. Using DC-specific antibodies, immunocytochemistry, flow cytometry and Ziehl-Neelsen (ZN) for bacilli staining, we searched for Mtb and DC changes within mediastinal lymph nodes, after intratracheal (ITT) inoculation of virulent Mtb. ZN and immunocytochemistry in frozen and paraffin sections of mediastinal lymph nodes identified Mtb until day 14 after ITT inoculation, associated with CD11c + and Dec205 + DC. Analysing CD11c, MHC-CII, and Dec205 combinations by flow cytometry in MLN suspensions revealed that CD11c + /MHC-CII + and CD11c +/Dec205 + DC did not increase until day 14, peaked on day 21, and sharply declined by day 28. No changes were seen in control, saline-inoculated animals. The costimulatory molecules evaluated in CD11c + DCs followed a similar trend; the ...
Another structurally similar compound, CC-5-V (CAS: 129738-34-7) was tested in a 28-day repeat-dose oral toxicity study (OECD 407) in Crj: CD (SD) IGS (SPF) rats at 5, 20, 80 and 320 mg/kg/d in warm olive oil. At 320 mg/kg/d effects on some clinical pathology parameters (e.g. white blood cells, thromboplastin time, LDH). At 80 mg/kg/d some clinical pathology parameters were also affected, but less pronounced. Treatment-related histopathological findings at 320 mg/kg/d consisted of hyperthrophy of alveolar lining cells in the lung, centrilobular hepatocellular hypertrophy, focal myocarditis and hypertrophy of the paracortex in the mediastinal lymph nodes, increased mitosis of hepatocytes and germinal center development in the mediastinal lymph nodes, foamy cells and focal proliferation of atypical pneumocytes in the lung, atypical basophilic tubules and mineralization of the cortico-medullary junction in the kidney. The histopathological and clinical pathology findings proved to be only partial ...
The results of this systematic review suggest that the transesophageal use of the echobronchoscope is a safe and effective method of accessing the mediastinum, and provides incremental diagnostic yield over and above that achieved with EBUS-TBNA alone. Overall, we found a good incremental yield (approximately 8%) of adding EUS-B-FNA to the EBUS-TBNA procedure in the diagnosis of mediastinal lymphadenopathy. The sensitivity of the combined technique was significantly higher than EBUS-TBNA alone (91% vs 80%), in mediastinal staging of lung cancer. In fact, only 10 combined procedures need to be performed to achieve a diagnosis in one additional patient, when compared with EBUS-TBNA alone. The sensitivity of the combined technique is similar to the sensitivity (86%) reported in a meta-analysis of combined EBUS-TBNA plus EUS-FNA by Zhang et al10 However, our analysis is different from the previous meta-analysis in that we have included only those studies that have utilized the same echobronchoscope ...

This chapter aims at introducing the interested Pulmonologist/Interventional Pulmonologist to the esophageal ultrasound. In this chapter, we give short descriptions of some technical aspects of the endobronchial ultrasound (EBUS) scope and explain in detail why we believe the EBUS scope is well suited to be an esophageal scope in the hands of the trained pulmonologist. The chapter then explains indications and benefits of this procedure that we consider central to the practice of chest physicians. We also describe in steps how to reach each lymph node station using the EBUS scope as a EUS scope (EUS-B) from our own experience. Procedure-related complications and contraindications are also described.

100 years ago, lung cancer was a rare disease.1 Over time it has become one of the leading causes of cancer death worldwide.2 Along with this the diagnostic and also the therapeutic implications have changed several times over the last few decades. In 1968 the first TNM description was published, trying to standardize the tumor staging and thereby the specific therapeutic recommendations. Today the 7th edition of the TNM system is still in use and the fact that the staging of the mediastinum is one of the most important topics has still not been challenged.3. In 1964 Werner Maaßen published his first full report about mediastinoscopy as a staging technique and in the following years the technique was established as the gold standard for the mediastinum.4. Even after the implementation of improved imaging techniques like computer tomography (CT) and Positron emissions tomography (PET), the surgical option was not discussed.3.
