Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL). DLBCL presents with pleural involvement at an advanced stage; however, primary pleural lymphomas without any other site of involvement are rare, and the possibility of misdiagnosis is high, particularly in developing countries, where tuberculosis or other severe pulmonary infections remain a major health concern. Furthermore, lymphoma and tuberculosis share a number of common clinical characteristics, such as fever, night sweats, feeling of satiety after a small meal, fatigue and unexplained weight loss, among others. We herein describe a case of misdiagnosis of primary pleural lymphoma as tuberculosis in a 49-year-old male patient who presented with pleural effusion and high adenosine deaminase (ADA) level in the pleural fluid. Anti-tuberculosis treatment was administered for 1 month, but the patient's condition deteriorated. A surgical biopsy was performed and was diagnostic of DLBCL. CHOP chemotherapy was administered with a significant delay due to the misdiagnosis, and it was not efficient, as rituximab was not added to the regimen. The therapeutic efficacy was monitored by computed tomography scans, which revealed that the lesion had shrunk slightly. The overall survival of the patient was ~1 year and he eventually succumbed to severe thoracic infection and pleural effusion. Suspicion should be raised when a patient presents with pleural effusion and extremely high ADA levels, as ADA activity of >250 U/L should raise the suspicion of empyema or lymphoma rather than tuberculosis.

In cases of pleural effusion, tissue samples can be obtained through Abrams needle pleural biopsy (ANPB), thoracoscopy, or cutting-needle pleural biopsy under the guidance of CT scan (CT-CNPB) for histopathologic analysis. This study aimed to compare the diagnostic efficiency and reliability of ANPB under CT scan guidance (CT-ANPB) with that of medical thoracoscopy in patients with pleural effusion. Between January 2006 and January 2008, 124 patients with exudative pleural effusion that could not be diagnosed by cytologic analysis were included in the study. All patients were randomized after the CT scan was performed. Patients either underwent CT-ANPB or thoracoscopy. The two groups were compared in terms of diagnostic sensitivity and complications associated with the methods used. Of the 124 patients, malignant mesothelioma was diagnosed in 33, metastatic pleural disease in 47, benign pleural disease in 42, and two were of indeterminate origin. In the CT-ANPB group, the diagnostic sensitivity was 87.5%, as compared with 94.1% in the thoracoscopy group; the difference was not statistically significant (P = .252). No difference was identified between the sensitivities of the two methods based on the cause, the CT scan findings, and the degree of pleural thickening. Complication rates were low and acceptable. We recommend the use of CT-ANPB as the primary method of diagnosis in patients with pleural thickening or lesions observed by CT scan. In patients with only pleural fluid appearance on CT scan and in those who may have benign pleural pathologies other than TB, the primary method of diagnosis should be medical thoracoscopy. clinicaltrials.gov; Identifier: NCT00720954.

Abstract Reactive oxygen species modulator 1 (Romo1) is a novel protein that plays an important role in intracellular reactive oxygen species generation. Recently, Romo1 has been suggested to have diagnostic and prognostic potential in lung cancer. However, there is no data on the diagnostic value of Romo1 level in malignant pleural effusion. We evaluated the clinical usefulness of Romo1 in pleural fluid for the diagnosis of malignant effusion in lung cancer patients. Pleural fluid Romo1 level was measured using enzyme-linked immunosorbent assay and compared between lung cancer-associated malignant effusion (n = 53; 29 adenocarcinomas and 24 squamous cell carcinomas) and benign pleural effusions (n = 91; 31 tuberculous pleurisy, 30 parapneumonic effusion, and 30 transudate). The discriminative power of Romo1 for lung cancer-associated malignant effusion was determined using receiver operating characteristic (ROC) curve analysis and compared with those of other tumor markers. Median Romo1 level in lung cancer-associated malignant effusion was 99.3 ng/mL, which was significantly higher than that in benign pleural effusions (P < 0.001). The optimal cutoff value of Romo1 to discriminate lung cancer-associated malignant effusion from benign effusions was 67.0 ng/mL with a sensitivity of 73.8% and a specificity of 84.1%. The area under the curve was 0.837 (95% confidence interval [CI]: 0.750–0.886), which was significantly better than that of cytokeratin 19 fragments (P < 0.001). Pleural fluid Romo1 could discriminate lung cancer from benign diseases with considerable sensitivity and specificity. Our findings suggest a diagnostic potential of Romo1 for lung cancer-associated malignant effusion. PMID:28121949

Hemostatic findings of pleural fluid in dogs and the association between pleural effusions and primary hyperfibrino(geno)lysis: A cohort study of 99 dogs

The primary objective of this study was to determine if activation of coagulation and fibrinolysis occurs in canine pleural effusions. Thirty-three dogs with pleural effusions of different origin were studied. Pleural effusion fibrinogen concentrations were significantly lower, while pleural fibrin-fibrinogen degradation products (FDPs) and D-dimer concentrations were significantly higher than those in plasma (P < 0.001 for all comparisons). These results show that, in canine pleural fluids, there is evidence of coagulation activation and fibrinolysis. The secondary aims of the current study were to determine if primary hyperfibrinolysis ([PHF] i.e., elevated plasma FDPs with a normal D-dimer concentrations), occurs in dogs with pleural effusion, and whether the presence of a concurrent inflammatory process may have activated the hemostatic cascade, with its intrinsically linked secondary hyperfibrinolysis, masking the concurrent PHF. The previously 33 selected dogs with pleural effusion (group 1) were compared to two control groups of 33 healthy (group 2) and 33 sick dogs without pleural effusion (group 3). Serum fibrinogen, FDPs, D-dimer, C-reactive protein (CRP), fibrinogen/CRP ratio, and frequency of PHF were determined. Fibrinogen, FDPs, D-dimer and CRP concentrations in group 1 were significantly increased compared to group 2 (P < 0.001 for all comparisons). FDPs and CRP concentrations in group 1 were also significantly increased compared to group 3 (P = 0.001 and P < 0.001, respectively). The fibrinogen/CRP ratio was significantly decreased in group 1 compared to groups 2 and 3 (P < 0.001 for both comparison). The frequency of PHF was significantly higher in group 1 compared to groups 2 (P = 0.004), but not compared to group 3. These results support the hypothesis that PHF occurs significantly more often in dogs with pleural effusion compared to healthy dogs. Nevertheless, the decrease in the fibrinogen/CRP ratio in group 1 compared to group 3, considering the higher FDPs and similar D-dimer concentrations, would suggest that PHF is also more frequent in dogs with pleural effusion compared to sick control dogs, and that this phenomenon is hidden due to concurrent secondary hyperfibrinolysis.

Pleural effusion is frequent in intensive care unit patients, but its impact on the outcome of weaning remains unknown. In a prospective study performed in three intensive care units, pleural ultrasound was performed at the first spontaneous breathing trial to detect and quantify pleural effusion (small, moderate, and large). Weaning failure was defined by a failed spontaneous breathing trial and/or extubation requiring any form of ventilatory support within 48 h. The primary endpoint was the prevalence of pleural effusion according to weaning outcome. Pleural effusion was detected in 51 of 136 (37%) patients and was quantified as moderate to large in 18 (13%) patients. As compared to patients with no or small pleural effusion, their counterparts were more likely to have chronic renal failure (39 vs. 7%; P = 0.01), shock as the primary reason for admission (44 vs. 19%; P = 0.02), and a greater weight gain (+4 [0 to 7] kg vs. 0 [-1 to 5] kg; P = 0.02). The prevalence of pleural effusion was similar in weaning success and weaning failure patients (odds ratio, 1.23; 95% CI, 0.61 to 2.49; P = 0.56), as was the prevalence of moderate to large pleural effusion (odds ratio, 0.89; 95% CI, 0.33 to 2.41; P = 1.00). Duration of mechanical ventilation and intensive care unit length of stay were similar between patients with no or small pleural effusion and those with moderate to large pleural effusion. Significant pleural effusion was observed in 13% of patients at the time of liberation from mechanical ventilation and was not associated with an alteration of weaning outcome.

Primary lymphoma of the lung or pleural is a very rare condition. Due to the outdated literature data, the approximate occurrence of primary and secondary lung and/or pleural involvement according to the most common B cell lymphoma entities is unknown. To answer this open question in Austria, we screened the Tyrolean registry for B cell non-Hodgkin's lymphomas regarding primary and secondary lung involvement. Of 854 patients affected by B cell lymphoma, 7.5% had lung/pleural disease. This organ was the primary site in only 0.7%, while a secondary involvement was registered in 6.8%. Most of them were affected by diffuse large B cell lymphoma (DLBCL; 29/368, 8%) followed by follicular lymphoma (7/188, 4%), mantle cell lymphoma (7/57, 12%), mucosa-associated tissue lymphoma (10/37, 27%), posttransplant lymphoproliferative disease (6/24, 25%), Burkitt lymphoma (3/19, 16%), other lymphomas (1/32, 3%) and Richter transformation (1/11, 9%). Moreover, primary lung/pleural lymphoma is one of the rarest neoplasias affecting the lung, accounting for only 0.4% of cases. Lung/pleural involvement is a very rare condition among B cell lymphomas since it mainly occurs in the setting of a generalized disease. A large majority of patients with secondary organ involvement are affected by DLBCL and have similar clinical features at diagnosis to others with advanced-stage disease. © 2014 S. Karger AG, Basel.

A common symptom during late stage breast cancer disease is pleural effusion, which is related to poor prognosis. Malignant cells can be detected in pleural effusions indicating metastatic spread from the primary tumor site. Pleural effusions have been shown to be a useful source for studying metastasis and for isolating cells with putative cancer stem cell (CSC) properties. For the present study, pleural effusion aspirates from 17 metastatic breast cancer patients were processed to propagate CSCs in vitro. Patient-derived aspirates were cultured under sphere forming conditions and isolated primary cultures were further sorted for cancer stem cell subpopulations ALDH1+ and CD44+CD24-/low. Additionally, sphere forming efficiency of CSC and non-CSC subpopulations was determined. In order to genetically characterize the different tumor subpopulations, DNA was isolated from pleural effusions before and after cell sorting, and compared with corresponding DNA copy number profiles from primary tumors or bone metastasis using low-coverage whole genome sequencing (SCNA-seq). In general, unsorted cells had a higher potential to form spheres when compared to CSC subpopulations. In most cases, cell sorting did not yield sufficient cells for copy number analysis. A total of five from nine analyzed unsorted pleura samples (55%) showed aberrant copy number profiles similar to the respective primary tumor. However, most sorted subpopulations showed a balanced profile indicating an insufficient amount of tumor cells and low sensitivity of the sequencing method. Finally, we were able to establish a long term cell culture from one pleural effusion sample, which was characterized in detail. In conclusion, we confirm that pleural effusions are a suitable source for enrichment of putative CSC. However, sequencing based molecular characterization is impeded due to insufficient sensitivity along with a high number of normal contaminating cells, which are masking genetic alterations of rare cancer (stem) cells.

This study aimed to determine the relationship between clinicopathologic features and lung squamous cell carcinoma (LSCC) subtypes according to the 2015 WHO classification. We identified 824 operable LSCC patients undergoing a complete surgical resection at Shanghai Chest Hospital between April 2015 and January 2017. Immunohistochemistry was used to investigate the clinicopathologic features. Among them, the percentages of LSCC subtypes were 66.1% (545/824), 28.6% (236/824), and 5.2% (43/824) for keratinizing squamous cell carcinoma (KSCC), nonkeratinizing squamous cell carcinoma (NKSCC), and basaloid squamous cell carcinoma (BSCC), respectively. There were more males, more smokers, and more pneumonectomy surgeries in KSCC patients (p = 0.008, p = 0.000, p = 0.043). There were more N2 lymph node involvement and pathological stage III in NKSCC patients (p = 0.01, p = 0.03). BSCC did not demonstrate specificity to anything, but expressed adenocarcinoma markers more frequently. No significant difference existed between pathological subtypes and other clinicopathologic features, such as age, location type, visceral pleural involvement and lymphovascular invasion. The frequencies of EGFR sensitive mutations and ALK rearrangements were not significantly different among three subtypes. Significant relationships exist between some clinicopathologic features and LSCC subtypes.

We present a case of a pleural space malignancy masked by an atypical presentation of mantle cell lymphoma. Our patient presented with a large pleural effusion and right sided pleural studding, initially attributed to a new diagnosis of mantle cell lymphoma. Rare atypical epithelial cells were also seen amongst the clonal population of lymphocytes. The patient lacked systemic manifestations of mantle cell lymphoma and did not improve with chemotherapy. A pleural biopsy ultimately revealed the presence of an undifferentiated carcinoma, favoring a lung primary. A discussion of synchronous pleural space malignancies involving lymphomas is given.

Southeast Asia is the major endemic area for paragonimiasis. Diagnosis relies on identification of ova in the sputum, pleural fluid or tissue specimen, or serology. Low awareness, however, frequently results in the disease being overlooked. We report nine cases presenting as primary, massive and protracted pleural effusions. All patients had evidence of Paragonimus spp. in the pleural fluid; one discharged an adult worm through a chest tube during treatment with praziquantel. In three cases, resolution of symptoms and pleural effusions could not be achieved, despite repeated fluid evacuation procedures and courses of praziquantel, which contradicts the widely accepted statement of paragonimiasis being self-limited and easy to cure. The disease should be considered in any case of elusive pleural effusion occurring in endemic areas.

Positron emission tomography (PET) now plays a clear role in oncology, especially in chest tumours. We discuss the value of metabolic imaging in characterising pleural pathology in the light of our own experience and review the literature. PET is particularly useful in characterising malignant pleural pathologies and is a factor of prognosis in mesothelioma. Metabolic imaging also provides clinical information for staging lung cancer, in researching the primary tumour in metastatic pleurisy and in monitoring chronic or recurrent pleural pathologies. PET should therefore be considered as a useful tool in the diagnosis of liquid or solid pleural pathologies. Copyright © 2010 SPLF. Published by Elsevier Masson SAS. All rights reserved.

Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by the infiltration of lymphocytes in exocrine glands, specifically the salivary and lacrimal glands, resulting in the typical symptoms of xerophthalmia and xerostomia. SS may be accompanied by pleural effusion when the lung is involved, but this occurrence has been reported in only 10 cases in the literature. We report the case of a 42 year-old woman with severe bilateral pleural effusion for eight years. Primary Sjögren's Syndrome was finally diagnosed based on the presence of xerophthalmia and xerostomia, biopsy of the minor salivary glands, and positive anti-SS-A antibody in the serum and pleural effusion. Biopsy of the parietal pleura through video-assisted thoracoscopy revealed infiltration of lymphocytes. The patient had a long history of pleural effusion without clear etiology. Malignant disease was first suspected because of abnormal density lesion on the left lung and malignant cells found on cytology, but PET-CT revealed no malignant lesion. Examinations did not support infection, malignant tumor, pulmonary sarcoidosis, or other connective tissue diseases. This data could be useful for the future study of pleural effusion in SS.

Primary spontaneous pneumothorax (PSP) represents a common indication for urgent surgical intervention in children. First episodes are often managed with thoracostomy tube, whereas recurrent episodes typically prompt surgery involving apical bleb resection and pleurodesis, either via pleurectomy or pleural abrasion. The purpose of this study was to assess whether pleurectomy or pleural abrasion was associated with lower postoperative recurrence. The records of patients undergoing surgery for PSP between February 2005 and December 2015 were retrospectively reviewed. Recurrence was defined as an ipsilateral pneumothorax requiring surgical intervention. Bivariate logistic regressions were used to identify factors associated with recurrence. Fifty-two patients underwent 64 index operations for PSP (12 patients had surgery for contralateral pneumothorax, and each instance was analyzed separately). The mean age was 15.7±1.2years, and 79.7% (n=51) of patients were male. In addition to apical wedge resection, 53.1% (n=34) of patients underwent pleurectomy, 39.1% (n=25) underwent pleural abrasion, and 7.8% (n=5) had no pleural treatment. The overall recurrence rate was 23.4% (n=15). Recurrence was significantly lower in patients who underwent pleurectomy rather than pleural abrasion (8.8% vs. 40%, p<0.01). In patients who underwent pleural abrasion without pleurectomy, the relative risk of recurrence was 2.36 [1.41-3.92, p<0.01]. Recurrence of PSP is significantly reduced in patients undergoing pleurectomy compared to pleural abrasion. Level III, retrospective comparative therapeutic study. Copyright © 2017 Elsevier Inc.

To explore the endoscopic features of patients with unexplained pleural effusion, and to evaluate the diagnostic value of medical thoracoscopy. A retrospective analysis of 2380 patients with unexplained pleural effusion (1320 males and 1060 females; age 15-94 years) in Shandong Provincial Hospital from 1992 to 2011 were performed .The diagnosis was confirmed by medical thoracoscopy. The endoscopic findings of malignant pleural effusion mostly showed nodules of varying sizes. The nodules could be grape-like, cauliflower-like, fused into masses, or diffused small nodules . The appearance of cancerous nodules was more diversified compared to tuberculous nodules. Tuberculous pleurisy was manifested as diffuse pleural congestion and miliary changes, multiple small gray-white nodules, fibrin deposition and adhesion in the pleural cavity, pleural thickening and loculation . The pathological diagnosis was as follows: pleural metastases in 899 (37.8%), primary pleural mesothelioma in 439 (18.4%), tuberculous pleurisy in 514 (21.6%), non-specific inflammation in 226 (9.5%), empyema in 190 (8.0%), hepatic pleural effusion in 36 (1.5%) and pleural effusion of unknown causes in 76 (3.2%) cases. The diagnostic positive rate of medical thoracoscopy was 96.8%. No serious complications were observed. Medical thoracoscopy is a relatively safe procedure and has an important application value in the diagnosis of unexplained pleural effusion.

Primary malignant pleural effusion has been reported in about 134 cases of multiple myeloma (MM). Associated pleural effusions in cases of MM portend a poor prognosis and identifying them is highly relevant. Reported is the case of a man diagnosed with MM who developed primary myelomatous pleural effusion in the setting of multiple relapses and subsequent mortality within 2 months of the pleural effusion diagnosis. A 61-year-old African American man was diagnosed with MM in 2011. He received induction therapy of lenalidomide and dexamethasone and an autologous stem cell transplant in 2012. Over the next 5 years, the patient went through alternating periods of remission and relapse that were treated with two rounds of thoracic spine radiation therapy and chemotherapeutic agents. In September 2017, the patient presented with worsening dyspnea and was found to have pleural effusion. Fluid analysis showed plasma cell dyscrasia. Fluid drainage was performed, then the patient was discharged after 1 week which was followed by rapid re-accumulation of fluid and rehospitalization about 10 days after discharge. The patient passed away a few weeks after the second admission. Pleural effusion carries a differential diagnosis which may include malignancy but is commonly thought to be less specific to multiple myeloma but should still remain in the differential diagnosis. To our knowledge, this is the first case of myelomatous pleural effusion (MPE) that was reported after multiple relapses of MM. MPE is a very rare complication of MM, and its presence is a strong indicator of imminent mortality and need for comfort care in case of multiple relapses. End-stage pleural effusion in MM in the setting of proteasome inhibitor adds more therapeutic and diagnostic challenges.

Primary cardiac lymphomas are exceedingly rare. The presence and extent of the intracardiac mass is determined by echocardiography, computed tomography (CT), or magnetic resonance imaging (MRI); however, the diagnosis is established by endomyocardial biopsy or by pericardial or pleural effusion cytology. We describe the pleural effusion cytologic features of a primary cardiac lymphoma in a 55-year-old woman who presented with progressive shortness of breath, fatigue, mild dizziness, dull chest ache, and lower extremity edema. Transthoracic echocardiography, CT, and MRI showed a large mass centered in the right atrium and extending into the right ventricle, associated with pericardial effusion and bilateral pleural effusions. Cytologic examination of the pleural fluid showed very large pleomorphic malignant cell, some of which were binucleated and multinucleated and had anaplastic features. Flow cytometry showed a kappa monotypic population of large cells coexpressing CD5, CD19, and CD20; and immunoperoxidase stains performed on the cell block sections showed that the large neoplastic cells were positive for CD20, PAX5, CD5, and MUM1 and showed a very high proliferation rate (over 90%) by Ki67 staining. The cytologic, flow cytometry, and immunohistochemistry findings established the diagnosis of de novo CD5-positive primary cardiac diffuse large B-cell lymphoma (DLBCL), anaplastic variant, which was confirmed by the subsequent endomyocardial biopsy. This is, to the best of our knowledge, the first report of de novo CD5-positive primary cardiac diffuse large B-cell lymphoma, and the first report of the anaplastic variant of DLBCL diagnosed by effusion cytology.

The role of ultrasonography in the management of lung and pleural diseases.

PubMed

Rumende, C Martin

2012-04-01

Ultrasonographic examination in pulmonology provides a revolutionary advance because it is very helpful in the diagnosis and management of various pleural and peripheral pulmonary defects. Lung ultrasonography allows the clinicians to diagnose some pulmonary abnormalities more rapidly, including the diagnosis of pleural effusion. Ultrasound examination also provides great assistance for the clinicians to perform invasive techniques in the field of pulmonology, which may increase the success rate and reduce the likelihood of complications. In addition to pleural effusion, other lung disorders can be diagnosed by ultrasound such as peripheral lung tumors and other pleural abnormalities caused by pleural fibrosis and tumor metastasis as well as the primary pleural tumor (mesothelioma). Ultrasound-guided invasive procedures include aspiration of minimal effusion, Transthoracal Needle Aspiration, Transthoracal biopsies and chest tube insertion. Lung ultrasound also offers other advantages, i.e. free from radiation hazards, portable, non-invasive and relatively inexpensive. Ultrasonography in the thorax also has its limitations, especially in detecting mediastinal abnormalities.

Can malignant and inflammatory pleural effusions in dogs be distinguished using computed tomography?

2017-09-01

Computed tomography (CT) is the primary imaging modality used to investigate human patients with suspected malignant or inflammatory pleural effusion, but there is a lack of information about the clinical use of this test in dogs. To identify CT signs that could be used to distinguish pleural malignant neoplasia from pleuritis, a retrospective case-control study was done based on dogs that had pleural effusion, pre- and postcontrast thoracic CT images, and cytological or histopathological diagnosis of malignant or inflammatory pleural effusion. There were 20 dogs with malignant pleural effusion (13 mesothelioma, 6 carcinoma; 1 lymphoma), and 32 dogs with pleuritis (18 pyothorax; 14 chylothorax). Compared to dogs with pleuritis, dogs with malignant pleural effusions were significantly older (median 8.5 years vs. 4.9 years, P = 0.001), more frequently had CT signs of pleural thickening (75% vs.44%, P = 0.04), tended to have thickening of the parietal pleura only (65% vs. 13%, P = 0.01) and had more marked pleural thickening (median 3 mm vs. 0 mm, P = 0.01). Computed tomography signs of thoracic wall invasion were observed only in dogs with malignant pleural effusions (P = 0.05). There were no significant differences in pleural fluid volume, distribution or attenuation, degree of pleural contrast accumulation, amount of pannus, or prevalence of mediastinal adenopathy. Although there was considerable overlap in findings in dogs with malignant pleural effusion and pleuritis, marked thickening affecting the parietal pleural alone and signs of thoracic wall invasion on CT support diagnosis of pleural malignant neoplasia, and may help prioritize further diagnostic testing. © 2017 American College of Veterinary Radiology.

Primary intestinal lymphangiectasia (Waldmann’s disease) is an exudative enteropathy characterized by lymph leakage into the small bowel lumen leading to hypoalbuminemia, hypogammaglobulinemia and lymphopenia (particularly T-cell). The diagnosis is based on viewing the duodenal lymphangiectasia. A 20 years old female patient, treated for a primary intestinal lymphangiectasia, has consulted for anasarca. Etiological work-up reveals pleural and pericardial tuberculosis. The clinical aggravation of an enteropathy, particularly in adulthood, requires a search for a secondary etiology. Tuberculosis should be sought systematically. PMID:28491220

Globally, there have been important changes in trends amongst gender, histology and smoking patterns of lung cancer cases. This retrospective study was conducted on 466 patients with lung cancer who were registered in Regional Cancer Center, Regional Institute of Medical Sciences, Manipur from January 2008 to December 2012. Most were more than 60 years of age (67.8%) with a male: female ratio of 1.09:1. Some 78.8% of patients were chronic smokers with male smoker to female smoker ratio of 1.43:1. Consumption of alcohol was found in 29.4%, both smoking and alcohol in 27.5%, betel nut chewing in 37.9% and tobacco chewing in 25.3%. A history of tuberculosis was present in 16.3% of patients. The most frequent symptom was coughing (36.6%) and most common radiological presentation was a mass lesion (70%). Most of the patients had primary lung cancer in the right lung (60.3%). The most common histological subtype was squamous cell carcinoma (49.1%), also in the 40-60 year age group (45.9%), more than 60 year age group (51.6%), males (58.1%) and females (41.8%). As many as 91.9% of squamous cell carcinoma patients had a history of smoking. About 32.5% of patients had distant metastasis at presentation with brain (23.8%) and positive malignant cells in pleural effusions (23.1%) as common sites. The majority of patients were in stage III (34.4%), stage IV (32.5%) and stage II (30.2%). Our analysis suggests that the gender gap has been narrowed such that about half of the patients diagnosed with lung cancer are women in this part of India. This alarming rise in female incidence is mainly attributed to an increased smoking pattern. Squamous cell carcinoma still remains the commonest histological subtype. Most of the patients were elderly aged and presented at locally or distantly advanced stages.

A 10-year-old, female spayed mixed-breed or cross-bred dog was referred to the Small Animal Teaching Hospital of the University of Liverpool due to tachypnea, dyspnea, and pleural effusion not responding to diuretics and antibiotics. The chest was drained and cytology of the pleural fluid was consistent with a modified transudate with presence of atypical cells initially attributed to mesothelial hyperplasia and dysplasia. Computed tomography detected, in addition to the bilateral pleural effusion, diffuse pleural thickening, multiple pleural and pulmonary nodules, and a mineralized and lytic mass in the left scapula. Imaging findings were suggestive of a primary bone tumor with intrathoracic metastasis. Cytology of the left scapular and pleural masses revealed a malignant neoplasm highly suggestive of osteosarcoma. The diagnosis was confirmed by demonstration of a positive cytochemical reaction for alkaline phosphatase on prestained cytology slides. This finding prompted review of the initial interpretation of the pleural effusion cytology. The presence of neoplastic osteoblasts in the thoracic fluid was identified by a combination of cytochemistry, cell pellet immunohistochemistry, and transmission electron microscopy findings. In this report, a multidisciplinary integrated diagnostic approach was used to diagnose and confirm a neoplastic pleural effusion due to osteosarcoma metastasis in a dog. © 2017 American Society for Veterinary Clinical Pathology.

In head and neck squamous cell carcinoma, second primary gastrointestinal tumors are not uncommon. However, it is unclear whether a screening endoscopy is needed for detecting gastrointestinal neoplasm in patients with head and neck cancer. Therefore, we analyzed the prevalence and independent risk factors for second primary gastrointestinal neoplasm in head and neck squamous cell carcinoma. A consecutive series of 328 patients with primary head and neck squamous cell carcinoma that underwent esophagogastroduodenoscopy or colonoscopy were included using our registry. An age- and sex-matched group of 328 control subjects was enrolled. We assessed risk factors of synchronous gastrointestinal cancer. The prevalence of esophageal cancer with head and neck squamous cell carcinoma was significantly higher than that of the control group (1.5% vs. 0.0%, p=0.011). An age of 54 years or more (OR, 1.033; 95% CI, 1.008-1.059; p=0.009) and male gender (OR, 4.974; 95% CI, 1.648-15.013; p=0.004) were risk factors for concomitant colorectal cancer or adenomas in the head and neck squamous cell carcinoma patients. Preoperative colonoscopy can be recommended for detecting synchronous second primary colorectal lesions in head and neck squamous cell carcinoma patients with male sex regardless of age, and esophagogastroduodenoscopy is necessary in all head and neck squamous cell carcinoma patients for detecting esophageal cancer.

Plasminogen Activator Inhibitor-1 Deficiency Augments Visceral Mesothelial Organization, Intrapleural Coagulation, and Lung Restriction in Mice with Carbon Black/Bleomycin–Induced Pleural Injury

Local derangements of fibrin turnover and plasminogen activator inhibitor (PAI)-1 have been implicated in the pathogenesis of pleural injury. However, their role in the control of pleural organization has been unclear. We found that a C57Bl/6j mouse model of carbon black/bleomycin (CBB) injury demonstrates pleural organization resulting in pleural rind formation (14 d). In transgenic mice overexpressing human PAI-1, intrapleural fibrin deposition was increased, but visceral pleural thickness, lung volumes, and compliance were comparable to wild type. CBB injury in PAI-1−/− mice significantly increased visceral pleural thickness (P < 0.001), elastance (P < 0.05), and total lung resistance (P < 0.05), while decreasing lung compliance (P < 0.01) and lung volumes (P < 0.05). Collagen, α-smooth muscle actin, and tissue factor were increased in the thickened visceral pleura of PAI-1−/− mice. Colocalization of α-smooth muscle actin and calretinin within pleural mesothelial cells was increased in CBB-injured PAI-1−/− mice. Thrombin, factor Xa, plasmin, and urokinase induced mesothelial–mesenchymal transition, tissue factor expression, and activity in primary human pleural mesothelial cells. In PAI-1−/− mice, D-dimer and thrombin–antithrombin complex concentrations were increased in pleural lavage fluids. The results demonstrate that PAI-1 regulates CBB-induced pleural injury severity via unrestricted fibrinolysis and cross-talk with coagulation proteases. Whereas overexpression of PAI-1 augments intrapleural fibrin deposition, PAI-1 deficiency promotes profibrogenic alterations of the mesothelium that exacerbate pleural organization and lung restriction.

This retrospective analysis reviews the clinical experience of a major urban referral hospital with diffuse malignant pleural mesothelioma during the 14-year period from 1973 through 1986. Seventy-five cases of definite or equivocal mesothelioma were identified. There were four cases of primary malignant peritoneal mesothelioma, seven cases of benign fibrous mesothelioma, and 64 cases of diffuse malignant pleural mesothelioma. In 43 cases (67%) of diffuse malignant pleural mesothelioma, there was historic evidence of asbestos exposure. In 21 cases (33%), there was no known history of asbestos exposure. An increase in annual incidence of diffuse malignant pleural mesothelioma was observed over themore » study period, from three cases in 1973 to ten cases in 1986. Despite greater awareness of this disease, the diagnosis remains a difficult one to establish given the nonspecific symptoms, signs and radiographic appearance, variable histologic appearance, and poor diagnostic sensitivity and specificity of thoracentesis and closed pleural biopsy. Thoracotomy, thoracoscopy, and CT-guided needle biopsies gave higher yields and are the diagnostic measures of choice when diffuse malignant pleural mesothelioma is suspected.« less

The Effect of Pleural Abrasion on the Treatment of Primary Spontaneous Pneumothorax: A Systematic Review of Randomized Controlled Trials

PubMed Central

Ming, Mo-yu; Cai, Shuang-qi; Chen, Yi-Qiang

2015-01-01

Background Pleural abrasion has been widely used to control the recurrence of primary spontaneous pneumothorax (PSP). However, controversy still exists regarding the advantages and disadvantages of pleural abrasion compared with other interventions in preventing the recurrence of PSP. Methods The PubMed, Embase, and Cochrane Central Register of Controlled Trials databases were searched up to December 15, 2014 to identify randomized controlled trials (RCTs) that compared the effects of pleural abrasion with those of other interventions in the treatment of PSP. The study outcomes included the PSP recurrence rate and the occurrence rate of adverse effects. Results Mechanical pleural abrasion and apical pleurectomy after thoracoscopic stapled bullectomy exhibited similarly persistent postoperative air leak occurrence rates (p = 0.978) and 1-year PSP recurrence rates (p = 0.821), whereas pleural abrasion led to reduced residual chest pain and discomfort (p = 0.001) and a smaller rate of hemothorax (p = 0.036) than did apical pleurectomy. However, the addition of minocycline pleurodesis to pleural abrasion did not reduce the pneumothorax recurrence rate compared with apical pleurectomy (3.8% for both procedures) but was associated with fewer complications. There was no statistical difference in the pneumothorax recurrence rate between mechanical pleural abrasion and chemical pleurodesis with minocycline on either an intention-to-treat basis (4 of 42 versus 0 of 42, p = 0.12; Fisher exact test) or after exclusions (2 of 40 versus 0 of 42, p = 0.24; Fisher exact test). Pleural abrasion plus minocycline pleurodesis also did not reduce the pneumothorax recurrence rate compared with pleural abrasion alone (p = 0.055). Moreover, pleural abrasion plus minocycline pleurodesis was associated with more intense acute chest pain. The postoperative overall recurrence rate in patients who underwent staple line coverage with absorbable cellulose mesh and fibrin glue was similar to that with mechanical abrasion after thoracoscopic bullectomy (13.8% vs. 14.2%, respectively; p = 0.555), but staple line coverage resulted in less postoperative residual pain than mechanical abrasion (0.4% vs.3.2%; p<0.0001). Pleural abrasion after thoracoscopic wedge resection did not decrease the recurrence of pneumothorax compared with wedge resection alone (p = 0.791), but the intraoperative bleeding and postoperative pleural drainage rates were higher when pleural abrasion was performed. Conclusions In addition to resulting in the same pneumothorax recurrence rate, thoracoscopic pleural abrasion with or without minocycline pleurodesis is safer than apical pleurectomy in the treatment of PSP. However, minocycline pleurodesis with or without pleural abrasion is not any more effective than pleural abrasion alone. Moreover, additional mechanical abrasion is not safer than additional staple line coverage with absorbable cellulose mesh and fibrin glue after thoracoscopic bullectomy because of increased postoperative pain. Additionally, pleural abrasion after thoracoscopic wedge resection should not be recommended for routine application due to the greater incidence of adverse effects than wedge resection alone. However, further large-scale, well-designed RCTs are needed to confirm the best procedure. PMID:26042737

Semi-rigid thoracoscopy is a safe and efficacious procedure in patients with undiagnosed pleural effusion. Literature on its utility from developing countries is limited. We herein describe our initial experience on the utility of semi-rigid thoracoscopy from a tertiary care teaching and referral center in north India. We also perform a systematic review of studies reporting the utility of semi-rigid thoracoscopy from India. The primary objective was to evaluate the diagnostic utility of semi-rigid thoracoscopy in patients with undiagnosed exudative pleural effusion. Semi-rigid thoracoscopy was performed under local anesthesia and conscious sedation in the bronchoscopy suite. A total of 48 patients underwent semi-rigid thoracoscopy between August 2012 and December 2013 for undiagnosed pleural effusion. Mean age was 50.9 ± 14.1 years (range: 17-78 years). Pre-procedure clinico-radiological diagnoses were malignant pleural effusion [36 patients (75%)], tuberculosis (TB) [10 (20.83%) patients], and empyema [2 patients (4.17%)]. Patients with empyema underwent the procedure for pleural biopsy, optimal placement of intercostal tube and adhesiolysis. Thoracoscopic pleural biopsy diagnosed pleural malignancy in 30 (62.5%) patients and TB in 2 (4.17%) patients. Fourteen (29.17%) patients were diagnosed with non-specific pleuritis and normal pleura was diagnosed on a pleural biopsy in 2 (4.17%) patients. Overall, a definitive diagnosis of either pleural malignancy or TB was obtained in 32 (66.7%) patients. Combined overall sensitivity, specificity, positive predictive value and negative predictive value of thoracoscopic pleural biopsy for malignant pleural effusion were 96.77%, 100%, 100% and 66.67%, respectively. There was no procedure-related mortality. On performing a systematic review of literature, four studies on semi-rigid thoracoscopy from India were identified. Semi-rigid thoracoscopy is a safe and efficacious procedure in patients with undiagnosed exudative pleural effusions.

Importance Indwelling pleural catheter and talc pleurodesis are established treatments for malignant pleural effusions among patients with poor prognosis. Objective To determine whether indwelling pleural catheters are more effective than talc pleurodesis in reducing total hospitalization days in the remaining lifespan of patients with malignant pleural effusion. Design, Setting, and Participants This open-label, randomized clinical trial included participants recruited from 9 centers in Australia, New Zealand, Singapore, and Hong Kong between July 2012 and October 2014; they were followed up for 12 months (study end date: October 16, 2015). Patients (n = 146) with symptomatic malignant pleural effusion who had not undergone indwelling pleural catheter or pleurodesis treatment were included. Interventions Participants were randomized (1:1) to indwelling pleural catheter (n = 74) or talc pleurodesis (n = 72), minimized by malignancy (mesothelioma vs others) and trapped lung (vs not), and stratified by region (Australia vs Asia). Main Outcomes and Measures The primary end point was the total number of days spent in hospital from procedure to death or to 12 months. Secondary outcomes included further pleural interventions, patient-reported breathlessness, quality-of-life measures, and adverse events. Results Among the 146 patients who were randomized (median age, 70.5 years; 56.2% male), 2 withdrew before receiving the randomized intervention and were excluded. The indwelling pleural catheter group spent significantly fewer days in hospital than the pleurodesis group (median, 10.0 [interquartile range [IQR], 3-17] vs 12.0 [IQR, 7-21] days; P = .03; Hodges-Lehmann estimate of difference, 2.92 days; 95% CI, 0.43-5.84). The reduction was mainly in effusion-related hospitalization days (median, 1.0 [IQR, 1-3] day with the indwelling pleural catheter vs 4.0 (IQR, 3-6) days with pleurodesis; P < .001; Hodges-Lehmann estimate, 2.06 days; 95% CI, 1.53-2.58). Fewer patients randomized to indwelling pleural catheter required further ipsilateral invasive pleural drainages (4.1% vs 22.5%; difference, 18.4%; 95% CI, 7.7%-29.2%). There were no significant differences in improvements in breathlessness or quality of life offered by indwelling pleural catheter or talc pleurodesis. Adverse events were seen in 22 patients in the indwelling pleural catheter group (30 events) and 13 patients in the pleurodesis group (18 events). Results Among 146 randomized patients (median age, 70.5 years; 56.2% male), 2 were excluded. The indwelling pleural catheter group spent significantly fewer days in hospital than the pleurodesis group. The reduction was mainly in effusion-related hospitalization days. Fewer patients randomized to indwelling pleural catheter required further ipsilateral invasive pleural drainages. There were no significant between-group differences in improvements in breathlessness or quality of life. Adverse events occurred in both groups: 30 events in 22 catheter patients and 23 events in 13 talc pleurodesis patients. Indwelling Pleural Catheter(n = 73) Talc Pleurodesis(n = 71) Estimated Difference in Location or Proportions (95% CI) P Value Primary Outcome Total all-cause hospital stay, median (IQR), d 10 (3-17) 12 (7-21) 2.92 (0.43-5.84) .03 Secondary Outcomes Effusion-related hospital stay, median (IQR), d 1 (1-3) 4 (3-6) 2.06 (1.53-2.58) <.001 Further ipsilateral invasive pleural procedures required, No. (%) 3 (4) 16 (22) 0.18 (0.08-0.29) .001 Conclusions and Relevance Among patients with malignant pleural effusion, treatment with an indwelling pleural catheter vs talc pleurodesis resulted in fewer hospitalization days from treatment to death, but the magnitude of the difference is of uncertain clinical importance. These findings may help inform patient choice of management for pleural effusion. Trial Registration anzctr.org.au Identifier: ACTRN12611000567921 PMID:29164255

Primary bronchus-associated lymphoid tissue (BALT) lymphoma comprises 5% of non-Hodgkin's lymphoma (NHL) and usually has an indolent course. Synchronous primary lung cancers with BALT lymphoma are seldom seen in patients with adenocarcinoma of the lung. Synchronous squamous cell carcinoma (SCC) and BALT lymphoma is an extremely rare occurrence. We report an unusual case of stage 4 BALT lymphoma requiring treatment that revealed an underlying ipsilateral mass causing a diagnostic dilemma. An 84-year-old female with a history of systemic lupus erythematosus, deep vein thrombosis, and thrombotic microangiopathy presented to the hospital with cough and dyspnea on exertion. A chest X-ray revealed right hemi-thorax opacification and computed tomography (CT) of the chest showed a large right effusion and a soft tissue density extending into the proximal right bronchus. She required repeated thoracentesis until the pleural fluid analysis showed the presence of small lymphocytes and bronchial washings revealed an abnormal B cell population consistent with extranodal marginal zone lymphoma. The patient received four cycles of bendamustine and rituximab resulting in near-complete resolution of the effusion. Four months from diagnosis, imaging showed an increase in the size of the soft tissue density with pathologic fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET). A CT-guided biopsy was consistent with squamous cell lung cancer (SCLC) and radiotherapy was started for clinical stage 2 disease since the patient was not a surgical candidate. BALT lymphoma is a low-grade malignancy classified as extranodal marginal zone lymphoma with a five-year survival rate of over 80%. Several cases of synchronous lung adenocarcinoma and BALT lymphoma have been described. However, our case is among the rare few cases of synchronous occurrence of SCLC with BALT lymphoma. This report highlights the challenges associated with establishing an accurate and timely diagnosis.

Primary intraosseous squamous cell carcinoma is an odontogenic tumour with aggressive behaviour usually noticed in 6th to 7th decades of life. The tumour is characterized by progressive swelling of the jaw, pain and loosening of teeth. Microscopically, the lesion is showing foci of keratinising cells separated by collagenous connective tissue stroma. A case of primary intraosseous squamous cell carcinoma of mandible arising de novo in a 40-year-old man is reported.

Squamous cell carcinoma presenting with trigeminal anesthesia: An uncommon presentation of head & neck cancer with unknown primary.

PubMed

Shah, Ameer T; Dagher, Walid I; O'Leary, Miriam A; Wein, Richard O

The differential diagnosis of facial anesthesia is vast. This may be secondary to trauma, neoplasm, both intracranial and extracranial, infection, and neurologic disease. When evaluating a patient with isolated facial anesthesia, the head and neck surgeon often thinks of adenoid cystic carcinoma, which has a propensity for perineural invasion and spread. When one thinks of head and neck squamous cell carcinoma with or without unknown primary, the typical presentation involves dysphagia, odynophagia, weight loss, hoarseness, or more commonly, a neck mass. Squamous cell carcinoma presenting as facial anesthesia and perineural spread, with no primary site is quite rare. Case presentations and review of the literature. Trigeminal anesthesia is an uncommon presentation of head and neck squamous cell carcinoma with unknown primary. We present two interesting cases of invasive squamous cell carcinoma of the trigeminal nerve, with no primary site identified. We will also review the literature of head and neck malignancies with perineural spread and the management techniques for the two different cases presented. Copyright © 2016 Elsevier Inc.

Adverse reactions associated to anti-thyroid drugs include fever, rash, arthralgia, agranulocytosis and hepatitis that are thought to be hypersensitivity reactions. Five cases of pleural effusion associated to thionamides have also been reported, two with propylthiouracil and three with carbimazole. We report here a case of a 75-year-old man admitted because of unilateral pleural effusion. The patient had a recent diagnosis of hyperthyroidism and 6 days after starting methimazole complained of pleuritic chest pain. He had elevated C-reactive protein and erythrocyte sedimentation rate and normal white blood cell count and liver enzymes. Chest radiography showed a moderate right pleural effusion and the ultrasound revealed a loculated effusion that was shown to be an eosinophilic exudate. The temporal relationship between methimazole intake and the development of pleural effusion combined with the extensive exclusion of alternative causes, namely infectious, neoplastic and primary auto-immune diseases, led to the diagnosis of hypersensitivity reaction to methimazole. The thionamide was stopped and corticosteroid was started with complete resolution of the pleural effusion in 3 months. Awareness of this rare adverse reaction of anti-thyroid drugs is important and methimazole can be added to the list of possible etiologies of drug-induced eosinophilic pleural effusion.

The incidence of oropharyngeal squamous cell carcinoma in the Western world is increasing, with the human papillomavirus epidemic implicated in this observed trend. The optimal treatment modality is yet undetermined regarding oncological outcomes. This study comprised 98 patients with oropharyngeal squamous cell carcinoma, treated with either primary transoral surgery with adjuvant therapy or primary chemoradiotherapy with curative intent, between 2008 and 2012. Clinicopathological characteristics including tumour-node-metastasis stage, human papillomavirus status, treatment modality, recurrence and overall survival were collated. Five per cent of primary surgical patients had locoregional recurrences compared with 25 per cent of primary chemoradiotherapy patients. A lower rate of locoregional recurrence was observed in the human papillomavirus positive group. This paper reports higher rates of overall survival and local control for oropharyngeal squamous cell carcinoma treated with primary surgery compared with primary chemoradiotherapy. This reflects overall lower tumour stage and higher human papillomavirus status in this group.

Fine needle aspiration biopsy of three cases of squamous cell carcinoma presenting as a thyroid mass: cytological findings and differential diagnosis.

PubMed

Rosa, M; Toronczyk, K

2012-02-01

Primary squamous cell carcinomas of the thyroid gland are extremely rare, comprising about 1% of thyroid malignancies. Although squamous cell carcinomas are readily identified as such on aspiration cytology in the majority of cases, the differentiation of primary versus metastatic tumour might not always be easy. Herein, we report three cases of squamous cell carcinomas involving the thyroid gland. Fine needle aspiration cytology (FNAC) was performed in three patients with a thyroid mass using standard guidelines. Smears were stained with Diff-Quik and Papanicolaou stains. Two patients were male and one was female, aged 59, 45 and 35 years, respectively. In all three patients a thyroid mass was present. FNAC smears in all cases showed cytological features of squamous cell carcinoma including keratinization and necrosis. After clinical and cytological correlation, one case appeared to be primary, one case metastatic, and in the third case no additional clinical information or biopsy follow-up was available for further characterization. Because primary squamous cell carcinoma of the thyroid is a rare finding, metastatic squamous cell carcinoma should always be excluded first. Metastatic disease usually presents in the setting of widespread malignancy, therefore a dedicated clinical and radiological investigation is necessary in these cases. In both clinical scenarios the patient's prognosis is poor. © 2010 Blackwell Publishing Ltd.

Pleural effusions are common in pediatrics. When the etiology of a pleural effusion remains unknown, adult literature recommends the use of Light's criteria to differentiate a transudate from an exudate. Pediatricians may rely on adult literature for the diagnostic management of pleural effusions as Light's criteria has not been validated in children. The purpose of this study was to review the use of Light's criteria in hospitalized children with a pleural effusion of unknown etiology. Retrospective review was performed on children hospitalized with a pleural effusion requiring chest tube placement or thoracentesis between January 1, 2016 to January 1, 2017 at Children's Hospital Colorado. Charts were reviewed for primary team, use of Light's criteria, pleural effusion diagnosis, and 30-day recurrence of repeat intervention or fluid analysis. Sixty-eight patients were hospitalized with a pleural effusion of unknown etiology requiring intervention. Only 16 pleural effusions (24%) were classified using Light's criteria. In those patients for whom Light's criteria was used, a diagnosis or change in management occurred in 10 of 16 patients (63%). Pleural effusions were most common on the cardiology service (26/68). Use of Light's criteria was most frequent on the oncology service (7/8). Thirty-day need for repeat intervention was lower in those with Light's criteria (13%) compared to those without (27%). Light's criteria were utilized infrequently in hospitalized children with a pleural effusion of unknown etiology at a single institution. There was considerable practice variation among provider teams. When utilized, Light's criteria assisted in making a diagnosis or changing management in many patients, and may lead to a reduction in 30-day recurrence requiring repeat intervention. © 2018 Wiley Periodicals, Inc.

Background: Semi-rigid thoracoscopy is a safe and efficacious procedure in patients with undiagnosed pleural effusion. Literature on its utility from developing countries is limited. We herein describe our initial experience on the utility of semi-rigid thoracoscopy from a tertiary care teaching and referral center in north India. We also perform a systematic review of studies reporting the utility of semi-rigid thoracoscopy from India. Patients and Methods: The primary objective was to evaluate the diagnostic utility of semi-rigid thoracoscopy in patients with undiagnosed exudative pleural effusion. Semi-rigid thoracoscopy was performed under local anesthesia and conscious sedation in the bronchoscopy suite. Results: A total of 48 patients underwent semi-rigid thoracoscopy between August 2012 and December 2013 for undiagnosed pleural effusion. Mean age was 50.9 ± 14.1 years (range: 17–78 years). Pre-procedure clinico-radiological diagnoses were malignant pleural effusion [36 patients (75%)], tuberculosis (TB) [10 (20.83%) patients], and empyema [2 patients (4.17%)]. Patients with empyema underwent the procedure for pleural biopsy, optimal placement of intercostal tube and adhesiolysis. Thoracoscopic pleural biopsy diagnosed pleural malignancy in 30 (62.5%) patients and TB in 2 (4.17%) patients. Fourteen (29.17%) patients were diagnosed with non-specific pleuritis and normal pleura was diagnosed on a pleural biopsy in 2 (4.17%) patients. Overall, a definitive diagnosis of either pleural malignancy or TB was obtained in 32 (66.7%) patients. Combined overall sensitivity, specificity, positive predictive value and negative predictive value of thoracoscopic pleural biopsy for malignant pleural effusion were 96.77%, 100%, 100% and 66.67%, respectively. There was no procedure-related mortality. On performing a systematic review of literature, four studies on semi-rigid thoracoscopy from India were identified. Conclusion: Semi-rigid thoracoscopy is a safe and efficacious procedure in patients with undiagnosed exudative pleural effusions. PMID:25814795

Breast abscess as the initial manifestation of primary pure squamous cell carcinoma: a rare presentation and literature review.

Salemis, Nikolaos S

2011-01-01

Primary squamous cell carcinoma of the breast is a very rare tumor accounting for less than 0.4% of all breast cancers. Fewer than 100 cases have been reported in the literature so far. The diagnosis requires strict pathologic criteria to be fulfilled. Due to the rarity of this tumor the optimal treatment and prognosis are both unclear. Breast abscess as the initial presentation of a primary squamous cell breast carcinoma is an extremely rare clinical entity. In this study, we describe a case of a 61-year-old postmenopausal woman who presented with typical manifestations of a breast abscess and was diagnosed with a pure primary squamous cell breast carcinoma. Diagnostic evaluation and management of the patient are discussed along with a review of the literature. Despite its rarity, the possibility of a primary pure squamous cell breast carcinoma should always be considered in the differential diagnosis in postmenopausal patients presenting with manifestations of a breast abscess, especially in those who respond poorly to the initial treatment. Physicians should be aware of this rare malignancy in order to avoid delays in diagnosis and treatment.

Report of two cases. The initial chest X-ray in both the cases showed pleural effusion. Further imaging with computed tomography of the chest confirmed the effusion in both cases. Thoracentesis was done in both of them revealed an exudative effusion that did not reveal any infection or malignancy. Both cases underwent surgical biopsy and the diagnosis of primary pleural epithelioid hemangioendothelioma was made. Both the cases had progressive clinical deterioration despite chemotherapy with Taxol and Bevacizumab in one case and carboplatin, etoposide, and bevacizumab, in the second case. Both developed metastatic disease to lungs and died. Published 2010. This article is a US Government work and is in the public domain in the USA.

18F-fluorodeoxyglucose imaging of primary malignant pericardial mesothelioma with concurrent pericardial and pleural effusions and bone metastasis: A case report.

Primary malignant pericardial mesothelioma (PMPM) is an aggressive tumor that originates from the mesothelial cells of the pericardium. PMPM with extensive atrial infiltration and bone metastasis is extremely rare. The diagnosis and staging of PMPM based on anatomical imaging may be difficult when concurrent pericardial and pleural effusions are present. A 28-year-old man presented with progressive chest pain. Concurrent pericardial and pleural effusions were identified on computed tomography. On echocardiography, mild thickening and adhesions of the pericardium with the right ventricle and atrium were observed. 18 F-fluorodeoxyglucose (FDG) metabolism imaging revealed increased accumulation in the pericardium and adjacent right atrium. Ring-shaped radioactivity aggregation and bone destruction in the sacrum were demonstrated on 18 F-FDG and 99m Tc-methyl diphosphonate imaging. The diagnosis of PMPM was subsequently confirmed by pathology. The patient survived for >1.5 years with comprehensive treatment.

We determined the molecular mechanisms that regulate the pathogenesis of malignant pleural effusion (PE) associated with advanced stage of human, non-small-cell lung cancer. Intravenous injection of human PC14 and PC14PE6 (adenocarcinoma) or H226 (squamous cell carcinoma) cells into nude mice yielded numerous lung lesions. PC14 and PC14PE6 lung lesions invaded the pleura and produced PE containing a high level of vascular endothelial growth factor (VEGF)-localized vascular hyperpermeability. Lung lesions produced by H226 cells were confined to the lung parenchyma with no PE. The level of expression of VEGF mRNA and protein by the cell lines directly correlated with extent of PE formation. Transfection of PC14PE6 cells with antisense VEGF165 gene did not inhibit invasion into the pleural space but reduced PE formation. H226 cells transfected with either sense VEGF 165 or sense VEGF 121 genes induced localized vascular hyperpermeability and produced PE only after direct implantation into the thoracic cavity. The production of PE was thus associated with the ability of tumor cells to invade the pleura, a property associated with expression of high levels of urokinase-type plasminogen activator and low levels of TIMP-2. Collectively, the data demonstrate that the production of malignant PE requires tumor cells to invade the pleura and express high levels of VEGF/VPF. PMID:11106562

We examined the efficacy of flavopiridol, a cyclin-dependent kinase inhibitor that is undergoing clinical trials, on primary cancer cells isolated from the ascites or pleural fluids of patients with metastatic cancers. Metastasized cancer cells were isolated from the pleural fluids (n = 20) or ascites (n = 15) of patients, most of whom were refractory to chemotherapy. These primary cancer cells were used within 2 weeks of isolation without selecting for proliferative capacities. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide viability assay was used to characterize the response of these cancer cells to commonly used chemotherapeutic agents, and their response to flavopiridol was compared with rapidly dividing cultured cell lines. The primary cancer cells displayed phenotypes that were different from established cell lines; they had very low replication rates, dividing every 1 to 2 weeks, and underwent replicative senescence within five passages. These primary tumor cells retained their resistance to chemotherapeutic drugs exhibited by the respective patients but did not show cross-resistance to other agents. However, these cancer cells showed sensitivity to flavopiridol with an average LD50 of 50 nmol/L (range, 21.5-69 nmol/L), similar to the LD50 in established cell lines. Because senescent cells also showed similar sensitivity to flavopiridol, it suggests that the mechanism of action is not dependent on the activity of cyclin-dependent kinases that regulate the progression of the cell cycle. Using cancer cells isolated from the ascites or pleural fluids, this study shows the potential of flavopiridol against cancer cells that have developed resistance to conventional chemotherapeutic agents.

Leukotriene B(4) (LTB(4)) plays a crucial role in the recruitment of neutrophils into the pleural space. We identified for the first time the mechanisms by which LTB(4) interacts with mesothelial cells and recruits neutrophils in the pleural compartment. Primary pleural mesothelial cells express both the proinflammatory receptor for LTB(4) BLT2, and the anti-inflammatory receptor for LTB(4), PPARalpha. Parapneumonic pleural effusions highly increase BLT2 expression and, via BLT2 activation, increase the adhesion between mesothelial cells and neutrophils and the expression of ICAM-1 on mesothelial cells. The block of PPARalpha further increases both cell adhesion and ICAM-1 expression. BLT2 activation promotes the activation, on mesothelial cells, of STAT-1 but not the activation of NF-kappaB transcription factor. The increase of ICAM-1 expression is achieved via increased tyrosine phosphorylation activity since herbimycin, a tyrosine kinase inhibitor, reduces and since Na orthovanadate, a tyrosine phosphatase inhibitor, further increases ICAM-1 expression. This study demonstrates that pleural mesothelial cells, expressing both proinflammatory and anti-inflammatory LTB(4) receptors, are able to mount an integrated response to LTB(4) with a prevalence of BLT2 activities in the presence of an inflammatory milieu within the pleura.

Purpose: To investigate the dose-volume histogram parameters and clinical factors as predictors of pleural effusion in esophageal cancer patients treated with concurrent chemoradiotherapy (CRT). Methods and Materials: Forty-three esophageal cancer patients treated with definitive CRT from January 2001 to March 2007 were reviewed retrospectively on the basis of the following criteria: pathologically confirmed esophageal cancer, available computed tomography scan for treatment planning, 6-month follow-up after CRT, and radiation dose {>=}50 Gy. Exclusion criteria were lung metastasis, malignant pleural effusion, and surgery. Mean heart dose, mean total lung dose, and percentages of heart or total lung volume receiving {>=}10-60 Gy (Heart-V{submore » 10} to V{sub 60} and Lung-V{sub 10} to V{sub 60}, respectively) were analyzed in relation to pleural effusion. Results: The median follow-up time was 26.9 months (range, 6.7-70.2) after CRT. Of the 43 patients, 15 (35%) developed pleural effusion. By univariate analysis, mean heart dose, Heart-V{sub 10} to V{sub 60}, and Lung-V{sub 50} to V{sub 60} were significantly associated with pleural effusion. Poor performance status, primary tumor of the distal esophagus, and age {>=}65 years were significantly related with pleural effusion. Multivariate analysis identified Heart-V{sub 50} as the strongest predictive factor for pleural effusion (p = 0.01). Patients with Heart-V{sub 50} <20%, 20%{<=} Heart-V{sub 50} <40%, and Heart-V{sub 50} {>=}40% had 6%, 44%, and 64% of pleural effusion, respectively (p < 0.01). Conclusion: Heart-V{sub 50} is a useful parameter for assessing the risk of pleural effusion and should be reduced to avoid pleural effusion.« less

Fine-needle aspiration cytology (FNAC) of serous membrane effusions may fulfil a challenging role in the diagnostic analysis of both primary and metastatic disease. From this perspective, liquid-based cytology (LBC) represents a feasible and reliable method for empowering the performance of ancillary techniques (ie, immunocytochemistry and molecular testing) with high diagnostic accuracy. In total, 3171 LBC pleural and pericardic effusions were appraised between January 2000 and December 2013. They were classified as negative for malignancy (NM), suspicious for malignancy (SM), or positive for malignancy (PM). The cytologic diagnoses included 2721 NM effusions (2505 pleural and 216 pericardic), 104 SM effusions (93 pleural and 11 pericardic), and 346 PM effusions (321 pleural and 25 pericardic). The malignant pleural series included 76 unknown malignancies (36 SM and 40 PM effusions), 174 metastatic lesions (85 SM and 89 PM effusions), 14 lymphomas (3 SM and 11 PM effusions), 16 mesotheliomas (5 SM and 11 SM effusions), and 3 myelomas (all SM effusions). The malignant pericardic category included 20 unknown malignancies (5 SM and 15 PM effusions), 15 metastatic lesions (1 SM and 14 PM effusions), and 1 lymphoma (1 PM effusion). There were 411 conclusive immunocytochemical analyses and 47 molecular analyses, and the authors documented 88% sensitivity, 100% specificity, 98% diagnostic accuracy, 98% negative predictive value, and 100% positive predictive value for FNAC. FNAC represents a primary diagnostic tool for effusions and a reliable approach with which to determine the correct follow-up. Furthermore, LBC is useful for ancillary techniques, such as immunocytochemistry and molecular analysis, with feasible diagnostic and predictive utility. © 2015 American Cancer Society.

Objective: Postoperative pleural adhesions lead to major problems in repeated thoracic surgery. To date, no antiadhesive product has been proven clinically effective. Previous studies of differently charged polypeptides, poly-L-lysine (PL) and poly-L-glutamate (PG) have shown promising results reducing postoperative abdominal adhesions in experimental settings. This pilot study examined the possible pleural adhesion prevention by using the PL+PG concept after pleural surgery and its possible effect on key parameters; plasmin activator inhibitor-1 (PAI-1) and tissue growth factor beta 1 (TGFb) in the fibrinolytic process. Methods: A total of 22 male rats were used in the study, one control group (n=10) and one experimental group (n=12). All animals underwent primary pleural surgery, the controls receiving saline in the pleural cavity and the experimental group the PL+PG solution administered by spray. The animals were evaluated on day 7. Macroscopic appearance of adhesions was evaluated by a scoring system. Histology slides of the adhesions and pleural biopsies for evaluation of PAI-1 and TGFb1 were taken on day 7. Results: A significant reduction of adhesions in the PL+PG group (p<0.05) was noted at day 7 both regarding the length and severity of adhesions. There were no significant differences in the concentration of PAI-1 and TGFb1 when comparing the two groups. Conclusions: PL+PG may be used to prevent pleural adhesions. The process of fibrinolysis, and fibrosis was though not affected after PLPG administration. PMID:24151443

Primary candidiasis and squamous cell carcinoma of the larynx: report of a case.

PubMed

Lee, Dong Hoon; Cho, Hyong Ho

2013-02-01

Primary candidiasis is rare and often confused with a pre-cancerous lesion, squamous cell carcinoma, or verrucous carcinoma. We report an extremely rare case of squamous cell carcinoma of the vocal cord following primary candidiasis. A 62-year-old man presented to our department reporting a 1-month history of hoarseness. He underwent laryngeal microscopic surgery for a presumptive diagnosis of glottic carcinoma. Histopathologic examination revealed candidiasis and scattered moderate dysplasia. He was treated with itraconazole for 4 weeks, and followed up without any recurrence of candidiasis. However, the 42-month follow-up examination revealed a focal whitish lesion on the right true vocal cord, and a repeat biopsy of this area revealed squamous cell carcinoma without evidence of candidiasis. The patient was treated with radiotherapy and remains well with no signs of tumor recurrence or candidiasis.

Primary spontaneous pneumothorax is a pathology mainly affecting healthy young patients. Clinical guidelines do not specify the type of pleurodesis that should be conducted, due to the lack of comparative studies on the different techniques. The aim of this study was to compare talc poudrage and pleural abrasion in the treatment of spontaneous pneumothorax. A retrospective comparative study was performed, including 787 patients with primary spontaneous pneumothorax. The 787 patients were classified into two groups: Group A (pleural abrasion) n = 399 and Group B (talc pleurodesis) n = 388. The variables studied were recurrence, surgical time, morbidity and in-hospital length of stay. Statistical analysis was done by an unpaired t-test and Fisher's exact test (SSPS 18.0). Statistically significant differences were observed in the variables: surgical time (A: 46 ± 12.3; B: 37 ± 11.8 min; P < 0.001); length of stay (A: 4.7 ± 2.5; B: 4.3 ± 1.8 days; P = 0.01); apical air camera (A: 25; B: 4; P < 0.001); pleural effusion (A: 6; B: 0; P = 0.05). Talc poudrage shows shorter surgical times and length of stay, and lower re-intervention rates. Morbidity is lower in patients with talc poudrage. Statistically significant differences were not observed in recurrence, persistent air leaks, atelectasis and haemothorax. PMID:22514256

The aim of this study was to identify predictors of mortality only in patients with malignant pleural effusion (MPE) showing good performance status which required pleural palliative procedures. All patients with MPE submitted to pleural palliative procedure were enrolled in a prospective study between 2013 and 2014. Patients with Eastern cooperative oncology group (ECOG) score zero, one, and two were considered with good performance status. The possible prognostic factors were tested for significance using the log-rank test (Kaplan-Meier method) and those with significance on univariate analysis were entered into a multivariable Cox model. A total of 64 patients were included in the analysis. Median follow-up time for surviving patients was 263 days. Median survival for the entire cohort was not reached yet. In the multivariate analysis, gastrointestinal primary site (P = 0.006), low albumin concentration in the pleural fluid (P = 0.017), and high serum NLR (P = 0.007) were associated with mortality. In our cohort of ECOG 0-2 patients with MPE submitted to pleural palliative procedures, gastrointestinal malignancy compared to other sites, low pleural fluid albumin and high NLR were significantly associated with mortality. The identification of these prognostic factors may assist the choice of the optimal palliative technique. J. Surg.

Malignant pleural effusion (MPE) denotes an advanced malignant disease process. Most of the MPE are metastatic involvement of the pleura from primary malignancy at lung, breast, and other body sites apart from lymphomas. The diagnosis of MPE has been traditionally made on cytological examination of pleural fluid and/or histological examination of pleural biopsy tissue that still remains the initial approach in these cases. There has been tremendous advancement in the diagnosis of MPE now a day with techniques i.e. characteristic Ultrasound and computed tomography features, image guided biopsies, fluorodeoxyglucose-positron emission tomography imaging, thoracoscopy with direct biopsy under vision, tumor marker studies and immunocytochemical analysis etc., that have made possible an early diagnosis of MPE. The management of MPE still remains a challenge to pulmonologist and oncologist. Despite having various modalities with better tolerance such as pleurodesis and indwelling pleural catheters etc., for long-term control, all the management approaches remain palliative to improve the quality of life and reduce symptoms. While choosing an appropriate management intervention, one should consider the clinical status of the patient, life expectancy, overall cost, availability and comparative institutional outcomes, etc. PMID:28360465

Mixed primary squamous cell carcinoma, follicular carcinoma, and micropapillary carcinoma of the thyroid gland: A case report.

Primary squamous cell carcinoma of the thyroid gland is rare, and mixed squamous cell and follicular carcinoma is even rarer still, with only a few cases reported in the literature. The simultaneous presentation of three primary cancers of the thyroid has not been reported previously. Here we report a case of primary squamous cell carcinoma of the thyroid, follicular thyroid carcinoma, and micropapillary thyroid carcinoma. A 62-year-old female patient presented with complaints of pain and a 2-month history of progressively increased swelling in the anterior region of the neck. Fine-needle-aspiration cytology of both lobes indicated the possibility of the presence of a follicular neoplasm. Total thyroidectomy with left-sided modified radical neck dissection was performed. Postoperative pathological examination confirmed the diagnosis of thyroid follicular carcinoma with squamous cell carcinoma and micropapillary carcinoma of the thyroid. Thyroid-stimulating hormone suppressive therapy with l-thyroxine was administered. Radioiodine and radiotherapy also were recommended, but the patient did not complete treatment as scheduled. The patient remained alive more than 9 months after operation. The present case report provides an example of the coexistence of multiple distinct malignancies in the thyroid.

The evolving role of interventional pulmonary in the interdisciplinary approach to the staging and management of lung cancer. Part III: diagnosis and management of malignant pleural effusions.

Yoneda, Ken Y; Mathur, Praveen N; Gasparini, Stefano

The diagnosis and management of a malignant pleural effusion can be one of the most vexing problems faced by physicians and their patients. Lung cancer is the most common primary tumor of origin with a prognosis that is limited, but variable and correlated with performance status (PS). Therefore, with a poor PS and known advanced lung cancer, establishing whether or not an effusion is malignant might not be necessary. Conversely, identifiable subsets of patients will have a much better survival, and establishing a definitive diagnosis could be of critical importance. In the great majority of cases, a diagnosis can be determined by serial thoracenteses with or without closed pleural biopsy. However, thoracoscopy is increasingly being utilized and can expedite the workup by obviating the need for repeated thoracenteses and/or closed pleural biopsy, while in the same setting providing definitive palliative treatment. Although studies comparing diagnostic and treatment strategies are limited, we will present the available data with the intention of providing the practicing oncologist with a practical strategy for the diagnosis and management of malignant pleural effusions due to lung cancer. The interventional pulmonologist can play an important role from diagnosis to palliation, greatly facilitating the care of patients with malignant pleural effusions.

Physiology and pathophysiology of pleural fluid turnover.

PubMed

Zocchi, L

2002-12-01

Tight control of the volume and composition of the pleural liquid is necessary to ensure an efficient mechanical coupling between lung and chest wall. Liquid enters the pleural space through the parietal pleura down a net filtering pressure gradient. Liquid removal is provided by an absorptive pressure gradient through the visceral pleura, by lymphatic drainage through the stomas of the parietal pleura, and by cellular mechanisms. Indeed, contrary to what was believed in the past, pleural mesothelial cells are metabolically active, and possess the cellular features for active transport of solutes, including vesicular transport of protein. Furthermore, the mesothelium was shown, on the basis of recent experimental evidence, both in vivo and in vitro, to be a less permeable barrier than previously believed, being provided with permeability characteristics similar to those of the microvascular endothelium. Direct assessment of the relative contribution of the different mechanisms of pleural fluid removal is difficult, due to the difficulty in measuring the relevant parameters in the appropriate areas, and to the fragility of the mesothelium. The role of the visceral pleura in pleural fluid removal under physiological conditions is supported by a number of findings and considerations. Further evidence indicates that direct lymphatic drainage through the stomas of the parietal pleura is crucial in removing particles and cells, and important in removing protein from the pleural space, but should not be the main effector of fluid removal. Its importance, however, increases markedly in the presence of increased intrapleural liquid loads. Removal of protein and liquid by transcytosis, although likely on the basis of morphological findings and suggested by recent indirect experimental evidence, still needs to be directly proven to occur in the pleura. When pleural liquid volume increases, an imbalance occurs in the forces involved in turnover, which favours fluid removal. In case of a primary abnormality of one ore more of the mechanisms of pleural liquid turnover, a pleural effusion ensues. The factors responsible for pleural effusion may be subdivided into three main categories: those changing transpleural pressure balance, those impairing lymphatic drainage, and those producing increases in mesothelial and capillary endothelial permeability. Except in the first case, pleural fluid protein concentration increases above normal: this feature underlies the classification of pleural effusions into transudative and exudative.

Detection of the E7 transform gene of human papilloma virus type 16 in human oral squamous cell carcinoma.

To determine, with the use of polymerase chain reaction, the prevalence of human papillomavirus (HPV) 16 in 30 patients with primary oral squamous cell carcinoma (OSCC) and 30 healthy control patients. DNA was extracted from freshly frozen tumor tissues of 30 patients with primary oral squamous cell carcinoma and from the oral mucosa of 30 controls. A pair of specific primers of the E7 early gene of HPV 16 were designed. PCR products were run by 1.5% agarose gel and the results of electrophoresis were photographed. HPV 16 was detected in 36.7% (11/30) of oral squamous cell carcinoma patients and 11.1% (4/30) of controls. HPV 16 has a significant association with oral squamous cell carcinoma. However, the role HPV 16 plays in the tumorigenesis of oral cancer and its clinical significance remain to be investigated.

MRI with DWI for the Detection of Posttreatment Head and Neck Squamous Cell Carcinoma: Why Morphologic MRI Criteria Matter.

2018-04-01

Although diffusion-weighted imaging combined with morphologic MRI (DWIMRI) is used to detect posttreatment recurrent and second primary head and neck squamous cell carcinoma, the diagnostic criteria used so far have not been clarified. We hypothesized that precise MRI criteria based on signal intensity patterns on T2 and contrast-enhanced T1 complement DWI and therefore improve the diagnostic performance of DWIMRI. We analyzed 1.5T MRI examinations of 100 consecutive patients treated with radiation therapy with or without additional surgery for head and neck squamous cell carcinoma. MRI examinations included morphologic sequences and DWI ( b =0 and b =1000 s/mm 2 ). Histology and follow-up served as the standard of reference. Two experienced readers, blinded to clinical/histologic/follow-up data, evaluated images according to clearly defined criteria for the diagnosis of recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment, post-radiation therapy inflammatory edema, and late fibrosis. DWI analysis included qualitative (visual) and quantitative evaluation with an ADC threshold. Recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment was present in 36 patients, whereas 64 patients had post-radiation therapy lesions only. The Cohen κ for differentiating tumor from post-radiation therapy lesions with MRI and qualitative DWIMRI was 0.822 and 0.881, respectively. Mean ADCmean in recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment (1.097 ± 0.295 × 10 -3 mm 2 /s) was significantly lower ( P < .05) than in post-radiation therapy inflammatory edema (1.754 ± 0.343 × 10 -3 mm 2 /s); however, it was similar to that in late fibrosis (0.987 ± 0.264 × 10 -3 mm 2 /s, P > .05). Although ADCs were similar in tumors and late fibrosis, morphologic MRI criteria facilitated distinction between the 2 conditions. The sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios (95% CI) of DWIMRI with ADCmean < 1.22 × 10 -3 mm 2 /s and precise MRI criteria were 92.1% (83.5-100.0), 95.4% (90.3-100.0), 92.1% (83.5-100.0), 95.4% (90.2-100.0), 19.9 (6.58-60.5), and 0.08 (0.03-0.24), respectively, indicating a good diagnostic performance to rule in and rule out disease. Adding precise morphologic MRI criteria to quantitative DWI enables reproducible and accurate detection of recurrent head and neck squamous cell carcinoma/second primary head and neck squamous cell carcinoma occurring after treatment. © 2018 by American Journal of Neuroradiology.

To investigate hypoxia-induced factor-1 alpha expression in distinct oral squamous cell carcinoma subtypes and topographies and correlate with clinicopathological data. Hypoxia-induced factor-1 alpha expression was assessed by immunohistochemistry in 93 cases of OSCC. Clinical and histopathological data were reviewed from medical records. Hypoxia-induced factor-1 alpha status was distinct according to tumor location, subtype and topography affect. In superficial oral squamous cell carcinomas, most tumor cells overexpressed hypoxia-induced factor-1 alpha, whereas hypoxia-induced factor-1 alpha was restricted to the intratumoral region in conventional squamous cell carcinomas. All basaloid squamous cell carcinomas exhibited downregulation of hypoxia-induced factor-1 alpha. Interestingly, metastatic lymph nodes (91.7%, p = 0.001) and the intratumoral regions of corresponding primary tumors (58.3%, p = 0.142) showed hypoxia-induced factor-1 alpha-positive tumor cells. Overall survival was poor in patients with metastatic lymph nodes. Hypoxia-induced factor-1 alpha has distinct expression patterns in different oral squamous cell carcinoma subtypes and topographies, suggesting that low oxygen tension promotes the growth pattern of superficial and conventional squamous cell carcinoma, but not basaloid squamous cell carcinoma. Indeed, a hypoxic environment may facilitate regional metastasis, making it a useful diagnostic and prognostic marker in primary tumors.

Tissue-engineering technologies have progressed rapidly through last decades resulting in the manufacture of quite complex bioartificial tissues with potential use for human organ and tissue regeneration. The manufacture of avascular monolayered tissues such as simple squamous epithelia was initiated a few decades ago and is attracting increasing interest. Their relative morphostructural simplicity makes of their biomimetization a goal, which is currently accessible. The mesothelium is a simple squamous epithelium in nature and is the monolayered tissue lining the walls of large celomic cavities (peritoneal, pericardial, and pleural) and internal organs housed inside. Interestingly, mesothelial cells can be harvested in clinically relevant numbers from several anatomical sources and not less important, they also display high transdifferentiation capacities and are low immunogenic characteristics, which endow these cells with therapeutic interest. Their combination with a suitable scaffold (biocompatible, degradable, and non-immunogenic) may allow the manufacture of tailored serosal membranes biomimetics with potential spanning a wide range of therapeutic applications, principally for the regeneration of simple squamous-like epithelia such as the visceral and parietal mesothelium vascular endothelium and corneal endothelium among others. Herein, we review recent research progresses in mesothelial cells biology and their clinical sources. We make a particular emphasis on reviewing the different types of biological scaffolds suitable for the manufacture of serosal mesothelial membranes biomimetics. Finally, we also review progresses made in mesothelial cells-based therapeutic applications and propose some possible future directions.

Squamous cell carcinoma (SCC) of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year's duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up.

We report a case of primary cutaneous neuroendocrine carcinoma (PCNEC) with squamous, glandular, and melanocytic differentiation and associated Bowen disease. The paranuclear globular positivity of low-molecular-weight cytokeratins agrees with the ultrastructural observations of paranuclear fibrous bodies in the small neuroendocrine cells, while the diffuse cytoplasmic positivity corresponds to the sparse intermediate filaments in large cells with squamous differentiation. "Transitional forms" are characterized by both diffuse and globular cytoplasmic positivity for cytokeratins and by the ultrastructural evidence of neuroendocrine and squamous features. Therefore the ultrastructural demonstration of intracytoplasmic tonofibrils and tonofilaments, intercellular glandular lumina, lined by well-formed microvilli, and immature premelanosomes in the neurosecretory cells supports the proposed tripartite differentiation of neuroendocrine cells of this case of PCNEC.

Introduction Malignant pleural effusion can complicate most cancers. It causes breathlessness and requires hospitalisation for invasive pleural drainages. Malignant effusions often herald advanced cancers and limited prognosis. Minimising time spent in hospital is of high priority to patients and their families. Various treatment strategies exist for the management of malignant effusions, though there is no consensus governing the best choice. Talc pleurodesis is the conventional management but requires hospitalisation (and substantial healthcare resources), can cause significant side effects, and has a suboptimal success rate. Indwelling pleural catheters (IPCs) allow ambulatory fluid drainage without hospitalisation, and are increasingly employed for management of malignant effusions. Previous studies have only investigated the length of hospital care immediately related to IPC insertion. Whether IPC management reduces time spent in hospital in the patients’ remaining lifespan is unknown. A strategy of malignant effusion management that reduces hospital admission days will allow patients to spend more time outside hospital, reduce costs and save healthcare resources. Methods and analysis The Australasian Malignant Pleural Effusion (AMPLE) trial is a multicentred, randomised trial designed to compare IPC with talc pleurodesis for the management of malignant pleural effusion. This study will randomise 146 adults with malignant pleural effusions (1:1) to IPC management or talc slurry pleurodesis. The primary end point is the total number of days spent in hospital (for any admissions) from treatment procedure to death or end of study follow-up. Secondary end points include hospital days specific to pleural effusion management, adverse events, self-reported symptom and quality-of-life scores. Ethics and dissemination The Sir Charles Gairdner Group Human Research Ethics Committee has approved the study as have the ethics boards of all the participating hospitals. The trial results will be published in peer-reviewed journals and presented at scientific conferences.

From 1921 to 1990, vermiculite ore from Libby, Montana, was shipped worldwide for commercial and residential use. A 1980 study of a manufacturing facility using Libby vermiculite was the first to demonstrate a small but significant prevalence of pleural chest radiographic changes associated with amphibole fibers contained in the ore. This follow-up study of the original cohort evaluated the extent of radiographic changes and cumulative fiber exposure (CFE) 25 years after cessation of exposure. From the original cohort of 513 workers, 431 (84%) were living and available for participation and exposure reconstruction. Of these, 280 (65%) completed both chest radiographs and interviews. Primary outcomes were pleural and/or interstitial changes. Pleural and interstitial changes were demonstrated in 80 (28.7%) and 8 (2.9%) participants, respectively. Of those participants with low lifetime CFE of less than 2.21 fiber/cc-years, 42 (20%) had pleural changes. A significant (P < 0.001) exposure-response relationship of pleural changes with CFE was demonstrated, ranging from 7.1 to 54.3% from the lowest to highest exposure quartile. Removal of individuals with commercial asbestos exposure did not alter this trend. This study indicates that exposure within an industrial process to Libby vermiculite ore is associated with pleural thickening at low lifetime CFE levels. The propensity of the Libby amphibole fibers to dramatically increase the prevalence of pleural changes 25 years after cessation of exposure at low CFE levels is a concern in view of the wide national distribution of this ore for commercial and residential use.

Malignant pleural effusion (MPE) is a known complication of both thoracic and extra thoracic malignancies. The presence of MPE regardless of the primary site translates into advanced stage disease. Diagnosis and management of MPE with the goals of palliation and improving quality of life poses a challenge for chest physicians. Recently, multiple studies have made attempts to answer questions regarding optimal management in various clinical scenarios. We will review the current evidence and available options for the management of MPE. PMID:29214068

Epidermotropic metastatic squamous cell carcinoma produced full-thickness cellular atypia of bowenoid carcinoma in situ or vulvar intraepithelial neoplasia, grade 3 (VIN 3), in a 73-year-old woman who had past history of uterine cervical carcinoma. The presence of intravascular tumor cell nests and areas showing smooth continuity of the malignant squamous cell nodules with the adjoining benign epidermis supported the possibility of the epidermotropic metastasis. To our knowledge, metastatic epidermotropic squamous carcinoma clinicopathologically simulating primary Bowen's disease has not been reported.

Prolonged air leak and high-volume pleural drainage are the most common causes for delays in chest tube removal following lung resection. While digital pleural drainage systems have been successfully used in the management of post-operative air leak, their effect on pleural drainage and inflammation has not been studied before. We hypothesized that digital drainage systems (as compared to traditional analog continuous suction), using intermittent balanced suction, are associated with decreased pleural inflammation and postoperative drainage volumes, thus leading to earlier chest tube removal. One hundred and three [103] patients were enrolled and randomized to either analog (n=50) or digital (n=53) drainage systems following oncologic lung resection. Chest tubes were removed according to standardized, pre-defined protocol. Inflammatory mediators [interleukin-1B (IL-1B), 6, 8, tumour necrosis factor-alpha (TNF-α)] in pleural fluid and serum were measured and analysed. The primary outcome of interest was the difference in total volume of postoperative fluid drainage. Secondary outcome measures included duration of chest tube in-situ, prolonged air-leak incidence, length of hospital stay and the correlation between pleural effusion formation, degree of inflammation and type of drainage system used. There was no significant difference in total amount of fluid drained or length of hospital stay between the two groups. A trend for shorter chest tube duration was found with the digital system when compared to the analog (P=0.055). Comparison of inflammatory mediator levels revealed no significant differences between digital and analog drainage systems. The incidence of prolonged post-operative air leak was significantly higher when using the analog system (9 versus 2 patients; P=0.025). Lobectomy was associated with longer chest tube duration (P=0.001) and increased fluid drainage when compared to sub-lobar resection (P<0.001), regardless of drainage system. Use of post-lung resection digital drainage does not appear to decrease pleural fluid formation, but is associated with decreased prolonged air leaks. Total pleural effusion volumes did not differ with the type of drainage system used. These findings support previously established benefits of the digital system in decreasing prolonged air leaks, but the advantages do not appear to extend to decreased pleural fluid formation.

Objectives To analyze the epidemiology and describe the prognostic indicators of patients with primary squamous cell carcinoma of the thyroid. Study Design and Setting Retrospective cohort study based on a national database. Methods The US National Cancer Institute's SEER registry (Surveillance, Epidemiology, and End Results) was reviewed for patients with primary squamous cell carcinoma of the thyroid from 1973 to 2012. Study variables included age, sex, race, tumor size, tumor grade, regional and distant metastases, and treatment modality. Survival measures included overall survival (OS) and disease-specific survival (DSS). Results A total of 199 cases of primary squamous cell carcinoma of the thyroid were identified. Mean age at diagnosis was 68.1 years; 58.3% were female; and 79.4% were white. Following diagnosis, 46.3% of patients underwent surgery; 55.7%, radiation therapy; and 45.8%, surgery with radiation therapy. Kaplan-Meier analysis demonstrated OS and DSS of 16% and 21% at 5 years, respectively. Median survival after diagnosis was 9.1 months. Multivariate Cox regression analysis showed that predictors of OS and DSS included age ( P < .001, P < .001, respectively), tumor grade ( P < .001, P = .001), and tumor size ( P < .001, P = .001). Surgical management was a predictor of OS but not DSS. Conclusion Squamous cell carcinoma of the thyroid is a rare malignancy with a very poor prognosis. Surgical resection confers an overall survival benefit. Age, tumor grade, and tumor size are predictors of OS and DSS.

A rare case of primary intraosseous squamous cell carcinoma arising in an odontogenic keratocyst (OKC) is presented here, with the clinical and histologic features of the first biopsy showing characteristics of OKC and the second biopsy disclosing a squamous cell carcinoma. Immunoprofile of this case was compared with five cases of classical OKC by using cytokeratins CK5, CK14, and CK19, CD138, p63, Ki-67, p53, and bcl-2. Classic OKCs showed expected positivity, mainly in the basal and/or suprabasal layers with most antibodies, except for p53, which was negative, whereas the present case showed irregular positivity in all layers, indicating that this can be useful for differential diagnosis and suggesting a possible role in malignant transformation into primary intraosseous squamous cell carcinoma. In conclusion, immunohistochemical differences between the first biopsy of the present case and classic OKC suggest that immunohistochemistry can be helpful in cases with areas of subtle initial malignant transformation.

PubMed

Gui, X H; Cao, M; Liu, Y; Cai, H R; Xiao, Y L

2016-10-12

Objective: To highlight the characteristics of pulmonary arterial involvement in Takayasu arteritis. Methods: The clinical and radiological data of a patient with Takayasu arteritis presenting with unilateral pleural effusion were studied and relevant literature was reviewed. The key words, "Takayasu arteritis" and "pleural effusion" were analyzed through literature retrieval in databases. Results: This 58 year-old female patient presented with shortness of breath. The chest CT scan showed bilateral hilar enlargement and pleural effusion on the left side. The blood pressure was not measurable in the course of the disease. After the aorticopulmonary-arteriography, we found that the pulmonary artery and the subclavian artery were involved. The diagnosis of Takayasu arteritis was made, and glucocorticoid therapy was initiated, with significant clinical and radiological improvement after therapy. Literature review found 4 cases of Takayasu arteritis with unilateral pleura effusion, ranging from 32 to 35 years of age, with a female predominance(Female∶Male=3∶1). The chief complaints were fever, chest pain and hemoptysis. All the patients recovered after the treatment of glucocorticoids. Conclusions: Takayasu arteritis presenting with unilateral pleural effusion was easily misdiagnosed as primary pulmonary diseases. Careful physical examination and timely angiography can be used to make the diagnosis.

2006-06-01

This paper reports a case of primary malignant diaphragmatic hemangiopericytoma in a 30-year-old male patient operated on for a diaphragmatic mass. The tumour was discovered on a TC scanning performed to explain the etiology of an exudative pleural effusion in a patient admitted for dyspnea, fever and thoracic pain. Given the rarity of this disease, the histological and pathological features of hemangiopericytoma are discussed in the light of the new classification system for soft tissue and bone tumours, as well as its currently accepted therapeutical guidelines.

Metastatic tonsillar squamous cell carcinoma masquerading as a pancreatic cystic tumor and diagnosed by EUS-guided FNA.

2017-11-01

Metastatic carcinoma to the pancreas is uncommon and head and neck squamous carcinoma metastatic to the pancreas is extremely rare. Metastatic squamous cell carcinoma to the pancreas presents a unique diagnostic challenge: in addition to mimicking the rare primary squamous cell carcinoma of the pancreas based on cytologic, histologic, and immunohistochemical features, it may be mistaken for a cystic neoplasm of the pancreas because of its high predilection for cystic degeneration in metastatic sites. Herein, we report a case of tonsillar squamous cell carcinoma with a cystic pancreatic metastasis diagnosed by ultrasound-guided fine needle aspiration biopsy (EUS-FNA). This represents a third reported case of metastatic squamous cell carcinoma to the pancreas from the head and neck region. Metastatic squamous cell carcinoma should be considered in the differential diagnosis of EUS-FNA during evaluation of pancreatic cystic lesion. © 2017 Wiley Periodicals, Inc.

The diagnostic evaluation and therapeutic management of a patient with squamous cell carcinoma of an unknown primary (SCCUP) has considerably evolved over recent decades and will likely continue to change as a result of the improving ability to identify small primary tumors and better tailor the implementation of multimodality therapy. By application of the general principles of head and neck oncology, physicians and surgeons are often able to achieve satisfactory control of the disease in patients with SCCUP.

2016-07-01

Malignant melanoma is one of the most aggressive and treatment resistant skin cancers. India enjoys a low incidence of melanoma, and age specific incidence rates for cutaneous malignant melanoma (CMM) are being less than 0.5 per 1,000,000. This could be due to under-reporting of melanoma on account of a low index of suspicion by clinicians and pathologists alike. Most common site for origin of primary melanoma is skin, accounting for about 91.2% of all reported primary malignant melanoma cases. Other primary sites are relatively uncommon. Primary pleural melanoma is a very rare tumor and to the best of our knowledge, only seven cases have been reported so far worldwide. We hereby discuss a new case, only second from India. Our patient also had coexistent congenital hairy nevus, an unusual association also noted in two previously reported cases. Excluding primary cutaneous melanoma with pleural metastasis was a diagnostic challenge in this case but multiple cutaneous biopsies together with clinical and findings helped us arrive at this unusual diagnosis. Unfortunately, the patient succumbed to his illness. Diagn. Cytopathol. 2016;44:648-652. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare central jaw carcinoma derived from odontogenic epithelial remnants. When the tumour arises in an existing cyst, it may be difficult to recognise early PIOSCC and carry out necessary treatment. We report a case diagnosed in a 50-year-old man where timely intervention was delayed and prognosis was affected and the case diagnosed eventually by comprehensive clinical, radiological and histopathological examination.

We aimed to determine whether infants undergoing cardiac surgery would more efficiently attain negative fluid balance postoperatively with passive peritoneal drainage as compared to traditional pleural drainage. A prospective, randomized study including children undergoing repair of tetralogy of Fallot (TOF) or atrioventricular septal defect (AVSD) was completed between September 2011 and June 2013. Patients were randomized to intraoperative placement of peritoneal catheter or right pleural tube in addition to the requisite mediastinal tube. The primary outcome measure was fluid balance at 48 hours postoperatively. Variables were compared using t tests or Fisher exact tests as appropriate. A total of 24 patients were enrolled (14 TOF and 10 AVSD), with 12 patients in each study group. Mean fluid balance at 48 hours was not significantly different between study groups, -41 ± 53 mL/kg in patients with periteonal drainage and -9 ± 40 mL/kg in patients with pleural drainage (P = .10). At 72 hours however, postoperative fluid balance was significantly more negative with peritoneal drainage, -52.4 ± 71.6 versus +2.0 ± 50.6 (P = .04). On subset analysis, fluid balance at 48 hours in patients with AVSD was more negative with peritoneal drainage as compared to pleural, -82 ± 51 versus -1 ± 38 mL/kg, respectively (P = .02). Fluid balance at 48 hours in patients with TOF was not significantly different between study groups. Passive peritoneal drainage may more effectively facilitate negative fluid balance when compared to pleural drainage after pediatric cardiac surgery, although this benefit is not likely universal but rather dependent on the patient's underlying physiology. © The Author(s) 2014.

To describe the radiological phenotype of HER2-mutant lung cancers on CT at presentation. Eligible patients with lung adenocarcinomas with HER2 mutations were stage-matched with two control groups (EGFR- and KRAS-mutant groups). Evaluated CT features of the primary tumor included size, location, consistency, contour, presence of pleural tags and pleural retractions. Presence of pleural effusions, lung metastases, adenopathy, chest wall invasion, and were also recorded. Wilcoxon rank-sum and Fisher's exact tests were used to compare continuous and categorical features, respectively. One hundred and fifty-four patients were identified: 50 (33%) harbored HER2 mutations, 56 (36%) harbored KRAS mutations, and 48 (31%) harbored EGFR mutations. Compared with KRAS, HER2 tumors presented as smaller lesions (2.3 cm versus 2.9 cm, p = 0.005 for length; 1.6 cm versus 2.1 cm, p = 0.002 for width) with the presence of pleural tags (74% vs. 52%, p = 0.03), pleural retractions (58% vs. 39%, p = 0.006), ipsilateral hilar (36% vs. 16%, p = 0.03) and scalene/supraclavicular N3 adenopathy (24% vs. 7%, p = 0.03). Compared with EGFR, pleural retractions were more prevalent among the HER2 tumors (58% vs. 37%, p = 0.05). Lung adenocarcinomas with HER2 gene mutation exhibit an aggressive behavior manifesting by higher incidence of local invasion, compared to KRAS and EGFR mutant controls, and a nodal metastatic spread compared to KRAS-mutant control. This is the first radiogenomics study of HER2 mutations in lung cancer. Copyright © 2018 Elsevier Inc. All rights reserved.

Pleural effusions occur frequently in patients requiring mechanical ventilatory support. Treatment of the precipitating cause and resolution of the pleural effusion may take considerable time. We retrospectively studied the effect of chest tube drainage of transudative pleural effusions on the liberation of patients from mechanical ventilatory support. Patients in the medical ICU (MICU) at Maimonides Medical Center between January 1, 2009, and October 31, 2009, requiring mechanical ventilatory support with a transudative pleural effusion, were studied retrospectively. They were divided into two groups: standard care and standard care plus chest tube drainage. Chest tubes were placed under ultrasound guidance by trained intensivists. Duration of mechanical ventilatory support was the primary end point. Secondary end points included measures of oxygenation, amount of fluid drained, and complications associated with the chest tube. A total of 168 patients were studied; 88 were treated with standard care and 80 underwent chest tube drainage. Total duration of mechanical ventilatory support was significantly shorter for patients who had chest tube drainage: 3.8±0.5 days vs 6.5±1.1 days for the standard group (P=.03). No differences in oxygenation were noted between the two groups. The average amount of fluid drained was 1,220 mL. No significant complications were caused by chest tube drainage. Chest tube drainage of transudative pleural effusions resulted in more rapid liberation from mechanical ventilatory support. It is a very safe procedure when performed under ultrasound guidance by experienced personnel. ClinicalTrials.gov; Identifier: NCT0114285; URL: www.clinicaltrials.gov.

Tuberculous pleuritis secondary to Mycobacterium bovis in a veterinarian.

Corcoran, John P; Hallifax, Robert J; Bettinson, Henry V; Psallidas, Ioannis; Rahman, Najib M

2016-07-01

Mycobacterium bovis is a rare cause of tuberculosis in humans, but should be considered in individuals at risk secondary to medical comorbidities (notably immunocompromise) or occupational exposure. Most cases are secondary to reactivation of latent infection in elderly individuals although cases of primary infection still occur, usually involving animal-to-human transmission. Pleural fluid culture in the context of suspected tuberculous pleuritis is frequently negative and pleural biopsy significantly increases the likelihood of confirming the diagnosis histologically and microbiologically. Although thoracoscopic biopsies are the reference standard, closed pleural biopsies are an appropriate and more accessible alternative in the majority of cases - these should be done under direct ultrasound guidance to maximise diagnostic yield. Treatment for M. bovis infection is with prolonged combination anti-tuberculous therapy, using an alternative to pyrazinamide as the organism is inherently resistant to this drug. © 2014 John Wiley & Sons Ltd.

Characterization of primary pulmonary adenosquamous carcinoma-associated pleural effusion.

A 10-year-old, female spayed Shih Tzu was presented due to weight loss, increased respiratory effort and lethargy, determined to be secondary to a congenital para-esophageal diaphragmatic defect with partial herniation of the stomach and spleen. Four days following reduction surgery of the displaced abdominal organs thoracic effusion developed. Thoracic fluid evaluation revealed a cell-rich, protein-poor modified transudate with neutrophils, reactive mesothelial cells, and atypical epitheloid cells which occasionally appeared to be keratinizing, consistent with neoplastic exfoliation. Thoracic effusion recurred 2 days later, with similar characteristics as the initial sample. Computed tomography (CT) indicated consolidation and displacement of the right middle and accessory lung lobes. Exploratory thoracic surgery demonstrated a thickened, hyperemic right middle lung lobe, and thickened pericardial diaphragmatic ligament. Histologic evaluation of these tissues identified a primary pulmonary adenosquamous carcinoma with intravascular and pleural invasion. Based on these cytologic, histologic, and clinical findings, we conclude that primary pulmonary carcinomas may involve superficial thoracic structures and exfoliate into a thoracic effusion. © 2016 American Society for Veterinary Clinical Pathology.

Recent studies have shown that some members of the tripartite motif-containing protein family function as important regulators for carcinogenesis. In this study, we investigated whether tripartite motif-containing protein 44 acts as a cancer-promoting gene through its overexpression in esophageal squamous cell carcinoma. We analyzed esophageal squamous cell carcinoma cell lines to evaluate malignant potential and also analyzed 68 primary tumors to evaluate clinical relevance of tripartite motif-containing protein 44 protein in esophageal squamous cell carcinoma patients. Expression of the tripartite motif-containing protein 44 protein was detected in esophageal squamous cell carcinoma cell lines (8/14 cell lines; 57%) and primary tumor samples of esophageal squamous cell carcinoma (39/68 cases; 57%). Knockdown of tripartite motif-containing protein 44 expression in esophageal squamous cell carcinoma cells using several specific small interfering RNAs inhibited cell migration and invasion, but not cell proliferation. Immunohistochemical analysis demonstrated that the overexpression of the tripartite motif-containing protein 44 protein in the tumor infiltrated region was associated with the status of lymph node metastasis ( p = 0.049), and the overall survival rates were significantly worse among patients with tripartite motif-containing protein 44-overexpressing tumors than those with non-expressing tumors ( p = 0.029). Moreover, multivariate Cox regression model identified that overexpression of the tripartite motif-containing protein 44 protein was an independent worse prognostic factor (hazard ratio = 2.815; p = 0.041), as well as lymphatic invasion (hazard ratio = 2.735; p = 0.037). These results suggest that tripartite motif-containing protein 44 protein could play a crucial role in tumor invasion through its overexpression and highlight its usefulness as a predictor and potential therapeutic target in esophageal squamous cell carcinoma.

We aimed to evaluate the feasibility and reliability of brush cytology in the biomarker expression profiling of oral squamous cell carcinomas within the concept of theranostics, and to correlate this biomarker profile with patient measurable outcomes. Markers representative of prognostic gene expression changes in oral squamous cell carcinoma was selected. These markers were also selected to involve pathways for which commercially available or investigational agents exist for clinical application. A set of 7 markers were analysed by immunocytochemistry on the archival primary tumour material of 99 oral squamous cell carcinoma patients. We confirmed the feasibility of the technique for the expression profiling of oral squamous cell carcinomas. Furthermore, our results affirm the prognostic significance of the epidermal growth factor receptor (EGFR) family and the angiogenic pathway in oral squamous cell carcinoma, confirming their interest for targeted therapy. Brush cytology appears feasible and applicable for the expression profiling of oral squamous cell carcinoma within the concept of theranostics, according to sample availability.

To determine the rate of chest radiographic abnormalities among residents of North Dakota potentially exposed to road gravel containing the fibrous mineral erionite. Participants (n = 34) completed a questionnaire, chest radiograph, and high resolution computed tomography scan to assess the rate of interstitial and pleural changes consistent with fibrous mineral exposure. Interstitial, pleural, or both changes typically associated with asbestos exposure were observed by high resolution computed tomography in seven (21%) individuals. The primary exposure pathway for six of these was from gravel pits, road maintenance, or both. Three participants (8.8%) demonstrated bilateral localized pleural changes with calcification; two of these also had accompanying interstitial changes. All three reported extensive work in gravel pits, road maintenance, or both. These results indicate that occupational exposure to erionite contained within road gravel in the United States represents a potential health hazard. This study identifies chest radiographic changes among residents of North Dakota occupationally exposed to road gravel containing erionite. Public health officials and physicians in affected areas should be aware of the potential health effects of erionite exposure. Precautionary measures should be taken to limit occupational exposure to gravel containing erionite.

The most common primary malignancy of the larynx is the squamous cell carcinoma (SCC). The primary malignant melanoma is quite rare in this location. Less than 60 cases of laryngeal melanomas have been reported to date. To our knowledge, collision primary malignant melanoma and invasive squamous cell carcinoma in the vocal cords has not been reported. We report a 53-year-old male patient who was diagnosed with a collision tumor of laryngeal melanoma and invasive SCC. Multiple Th17 pathway related genes including CTLA-4, IL-17A-F, PLZF, FoxP3, RorγT, CD27, and CD70 were analyzed by reverse transcriptase-polymerase chain reaction (Rt-PCR) in this case. Both IL-17A and CD70 genes were detected in this case of collision tumor. The results may define useful biomarkers for early diagnosis of mucosal melanoma and open an immunotherapeutic field for clinical management with the potential benefit from the immunomodulators that enhance both genes.

In head and neck squamous cell carcinoma (HNSCC), the occurrence of concurrent lung malignancies poses a significant diagnostic challenge because metastatic HNSCC is difficult to discern from second primary lung squamous cell carcinoma (SCC). However, this differentiation is crucial because the recommended treatments for metastatic HNSCC and second primary lung SCC differ profoundly. We analyzed the origin of lung tumors in 32 patients with HNSCC using human papillomavirus (HPV) typing and targeted next generation sequencing of all coding exons of tumor protein 53 (TP53). Lung tumors were clearly identified as HNSCC metastases or second primary tumors in 29 patients, thus revealing that 16 patients had received incorrect diagnoses based on clinical and morphological data alone. The HPV typing and mutation analysis of all TP53 coding exons is a valuable diagnostic tool in patients with HNSCC and concurrent lung SCC, which can help to ensure that patients receive the most suitable treatment. © 2018 Wiley Periodicals, Inc.

The paper gives a clinical observation of a 52 year-old male with a rare histological urinary bladder tumor primary grandular-squamous-cell carcinoma (pT3N IM0). The tumor is represented by two components large acinic-cell adenocarcinoma and squamous-cell carcinoma with keratinization, which smoothly pass one into another; the tumor has grown through all layers of the urinary bladder wall but it has failed to grow into the peritoneum. A microscopic study has indicated that the urachus is intact. Metastases were found in 3 of 8 lymph nodes: one showed high-grade adenocarcinoma and two others displayed average-grade squamous-cell carcinoma.

Introduction Non-expansile lung (NEL) is a common cause of talc pleurodesis (TP) failure in malignant pleural effusion (MPE), but is often occult prior to drainage. Reliable detection of NEL would allow patients to be allocated between intrapleural catheter (IPC) and TP. High pleural elastance (PEL) has been associated with NEL in observational studies. Pre-EDIT is a randomised feasibility trial of elastance-directed IPC or TP (EDIT) management using a novel, purpose-built digital pleural manometer (Rocket Medical, UK). Methods and analysis Consecutive patients with MPE without prior evidence of NEL or preference for IPC will be randomised 1:1 between EDIT management and standard care (an attempt at TP). The primary objective is to determine whether sufficient numbers of patients (defined as 30 within 12 months (or 15 over 6 months)) can be recruited and randomised to justify a subsequent phase III trial testing the efficacy of EDIT management. Secondary objectives include safety, technical feasibility and validation of study design elements, including the definition of PEL using 4D pleural MRI before and after fluid aspiration. EDIT involves PEL assessment during a large volume pleural fluid aspiration, followed by an attempt at TP or placement of an IPC within 24 hours. Patients will be allocated to IPC if the rolling average PEL sustained over at least 250 mL fluid aspirated (PEL250) is ≥ 14.5 cm H2O/L. Ethics and dissemination Pre-EDIT was approved by the West of Scotland Regional Ethics Committee on 8 March 2017 (Ref: 17/WS/0042). Results will be presented at scientific meetings and published in peer-reviewed journals. Trial registration number NCT03319186; Pre-results. PMID:29862030

Most primarily cultured laryngeal squamous cell carcinoma cells are difficult to propagate in vitro and have a low survival rate. However, in our previous work to establish a laryngeal squamous cell carcinoma cell line, we found that laryngeal cancer-associated fibroblasts appeared to strongly inhibit the apoptosis of primarily cultured laryngeal squamous cell carcinoma cells in vitro. In this study, we investigated whether paired laryngeal cancer-associated fibroblasts alone can effectively support the growth of primarily cultured laryngeal squamous cell carcinoma cells in vitro. In all, 29 laryngeal squamous cell carcinoma specimens were collected and primarily cultured. The laryngeal squamous cell carcinoma cells were separated from cancer-associated fibroblasts by differential trypsinization and continuously subcultured. Morphological changes of the cultured laryngeal squamous cell carcinoma cells were observed. Immunocytofluorescence was used to authenticate the identity of the cancer-associated fibroblasts and laryngeal squamous cell carcinoma cells. Flow cytometry was used to quantify the proportion of apoptotic cells. Western blot was used to detect the protein levels of caspase-3. Enzyme-linked immunosorbent assay was used to detect the levels of chemokine (C-X-C motif) ligand 12, chemokine (C-X-C motif) ligand 7, hepatocyte growth factor, and fibroblast growth factor 1 in the supernatants of the laryngeal squamous cell carcinoma and control cells. AMD3100 (a chemokine (C-X-C motif) receptor 4 antagonist) and an anti-chemokine (C-X-C motif) ligand 7 antibody were used to block the tumor-supporting capacity of cancer-associated fibroblasts. Significant apoptotic changes were detected in the morphology of laryngeal squamous cell carcinoma cells detached from cancer-associated fibroblasts. The percentage of apoptotic laryngeal squamous cell carcinoma cells and the protein levels of caspase-3 increased gradually in subsequent subcultures. In contrast, no significant differences in the proliferation capacity of laryngeal squamous cell carcinoma cells cocultured with cancer-associated fibroblasts were detected during subculturing. High level of chemokine (C-X-C motif) ligand 12 was detected in the culture supernatant of cancer-associated fibroblasts. The tumor-supporting effect of cancer-associated fibroblasts was significantly inhibited by AMD3100. Our findings demonstrate that the paired laryngeal cancer-associated fibroblasts alone are sufficient to support the primary growth of laryngeal squamous cell carcinoma cells in vitro and that the chemokine (C-X-C motif) ligand 12/chemokine (C-X-C motif) receptor 4 axis is one of the major contributors.

Studies on omeprazole have reported that doses as low as 0.7 mg/kg bwt per os are potent suppressors of acid production. Yet, to date, no studies have compared treatment efficacy of different doses in clinical cases of equine gastric ulceration. Furthermore, no studies have been performed to compare the healing response of the squamous and glandular mucosa to acid suppression therapy. To compare: 1) the efficacy of 2 doses of omeprazole in the treatment of primary squamous and glandular gastric ulceration; and 2) the healing response of primary squamous and glandular gastric ulceration to acid suppression therapy. A blinded, randomised, dose-response clinical trial. Twenty Thoroughbred racehorses with grade ≥2/4 glandular ulceration were identified on gastroscopy. Seventeen horses also had grade ≥2/4 squamous ulceration. Horses were randomly assigned to one of 2 groups. Horses received either 2.0 g (high dose: 4.0 mg/kg bwt) or 0.8 g (low dose: 1.6 mg/kg bwt) of oral omeprazole per os once daily. Gastroscopy was repeated at 28-35 days. Time and dose significantly affected grades of squamous (P<0.0001, P = 0.02) and glandular (P = 0.006 and 0.005) ulceration. Data analysis did not support our hypothesis that the lower dose would have similar effects (i.e. be noninferior) to the higher dose when considering ulcer healing and ulcer improvement. Improvement was more likely with the high dose for the squamous (P = 0.05) but not glandular (P = 0.4) mucosa. The percentage of glandular ulcers that improved was less than squamous ulcers (P = 0.02). The results suggest that a dose-response exists for the treatment of both squamous and glandular ulcers. Improvement of glandular ulcers was not as complete as observed with squamous ulcers and current equine gastric ulcer syndrome treatment recommendations may not be appropriate for glandular disease. © 2013 EVJ Ltd.

Objective: To optimize the clinical managements of primary fetal hydrothorax (PFHT) fetus by comparing the perinatal survival rate of different prenatal treatments. Methods: Totally 13 fetuses diagnosed with PFHT from July 2009 to December 2015 in the First Affiliated Hospital of Jinan University were collected and received prenatal expectant treatment, thoracocentesis (TC), and thoraco-amniotic shunting (TAS), respectively. The perinatal survival rate was compared among the three treatments. Results: Among 13 fetuses of PFHT, pleural effusion was absorbed or remained stable in 2(2/13) cases, and progressed in 11(11/13) cases. Six cases received expectant treatment (2 cases had termination of pregnancy due to progressing effusion, 2 cases had term delivery, and 2 cases had intrauterine death); the perinatal survival rate was 2/6. Six cases received TC (2 cases had term delivery, 2 cases had preterm delivery, and 2 cases had termination of pregnancy due to progressing effusion), the perinatal survival rate was 4/6. One case received TC+TAS (term delivery), the perinatal survival rate was 1/1. The overall perinatal survival rate of prenatal intrauterine intervention was 5/7. Conclusions: The clinical process of PFHT is changeable, and the pleural effusion will progress with gestational age. Intrauterine interventions could improve the perinatal survival rate.

Metastases in renal carcinoma are diagnosed at initial diagnosis in 25% examinees. Traditional renal carcinoma has higher metastatic potential, is associated with worse survival of the patients compared to papillary cancer. We studied cytological characteristics of renal carcinoma metastases to the pleura in comparison with histological studies of the primary lesion using immunohistochemical findings. We examined cytologically pleural liquid in renal carcinoma metastases to the pleura in 6 patients (2.3% of carcinomatous pleuricies). High efficacy was shown by a cytocentrifuge CYTOSPIN-4. In 3 cases initial cancer was renal cell carcinoma, pleural exudation developed 2 years later, clear cell carcinoma appeared 6 years later and papillary cancer--10 years later. In the other 3 cases malignant cells were detected in new-onset cases. Renal carcinoma was diagnosed in one case. Cytological preparations were studied with identification of cytological signs typical for classic clear cell, granulocell and papillary renal cancer. Immunohistochemical examination of primary tumor lesion in the kidney discovered high proliferative activity of tumor cells by Ki-67 index to 5.28%. The tumors had solitary Bcl-2 positive cells. Expression of mutant p-53 took place in 0.93%. Her-2/neu hyperexpression was not found in the tumors of the above patients. Such immunohistochemical parameters point to poor prognosis. This is confirmed by renal carcinoma metastases to the pleura.

Immunocompromised patients with metastatic cutaneous nodal head and neck squamous cell carcinoma (HNSCC) have worse outcomes compared to the immunocompetent. The purpose of this study was to investigate the characteristics of the primary cutaneous squamous cell carcinoma (SCC), nodal pathology, and outcome between these 2 groups. Analysis of a prospective database was performed. A 2:1 pooled analysis selected 46 immunocompetent patients matched with 23 immunocompromised patients. Overall survival (OS) and relapse-free survival (RFS) were calculated using the Kaplan-Meier method. No significant difference was found in the primary tumor characteristics between the 2 groups. In the immunocompromised group, RFS (hazard ratio [HR] 2.70; P = .01) and OS (HR 2.32; P = .04) were significantly worse. Extracapsular spread was present in 100% of the immunocompromised patients. No significant difference was identified in the primary cutaneous SCC between the immunocompetent and immunocompromised patients. Immunosuppression predicted worse outcome. © 2018 Wiley Periodicals, Inc.

Black pleural effusion (BPE) is an extremely uncommon type of pleural fluid, which can be due to infection, primary or metastatic malignancy, and hemorrhage. As reported in previous studies, BPE is also observed in some patients with pancreatic pseudocyst. We herein reported a case of a 14-year-old female patient who was admitted to our center with a history of cough for 1 and a half months and right chest pain for 1 month. Before this, she was consecutively hospitalized in 3 different hospitals due to the same symptoms. However, the previous treatments were ineffective due to the lack of a definitive diagnosis. Laboratory examination of the pleural effusion showed BPE with a high amylase concentration. Chest x-ray and computed tomography (CT) showed massive pleural effusion, more prominent in the right chest. CT and MRCP of the abdomen showed a cystic lesion located in the tail of the pancreas, which entered the chest cavity via an esophageal hiatal hernia. DIAGNOSES:: pancreatic pseudocyst. After confirming that the tumor was a pancreatic pseudocyst by intraoperative biopsy, internal drainage to the jejunum was performed. The postoperative recovery was rapid and without complications, and the final discharge diagnosis was idiopathic pancreatic pseudocyst (without history of pancreatitis or pancreatic injuries) with BPE of the right chest. This case demonstrates that massive BPE could present as a rare complication of pancreatic pseudocyst, and surgery is a potential treatment for such patients. Copyright © 2017 The Authors.

Neck dissections that include sublevel IIb increase the risk of postoperative shoulder dysfunction. The purpose of this investigation was to document the incidence of level IIb metastatic lymphatic spread in a group of patients undergoing neck dissection as part of the surgical management of cutaneous squamous cell carcinoma of the head and neck. A retrospective review of the pathology records taken from 1 surgeon from June 2006 through June 2013 was carried out. The predictor variable was the primary tumor site. The outcome variable was the metastatic nodal involvement according to neck level and sublevel. Secondary variables included T stage, pathologist, tumor depth, and the presence of perineural, perilymphatic, and perivascular invasion. Data analyses were by descriptive statistics. Thirty-six patients with a total of 40 neck dissections met the inclusion criteria. The average primary site tumor depth was 14.7 mm, and there were 16 cases of poorly differentiated squamous cell carcinoma. Sublevel IIb was involved in 7.5% of cases, all of which occurred from lateralized primary sites of the head and neck. Cutaneous squamous cell carcinoma arising from the auricle and neck sites adjacent to sublevel IIb may have increased risk of metastatic involvement of sublevel IIb nodes. Further studies with larger numbers are required to determine the risk of metastasis to sublevel IIb from midline sites of the face. Crown Copyright © 2014. Published by Elsevier Inc.

Somatic LKB1 serine/threonine kinase alterations are rare in sporadic cancers, with the exception lung adenocarcinoma, but no mutations in squamous cell or large cell primary carcinoma were discovered. We screened the LKB1 gene in 129 primary nonsmall cell lung carcinomas, adjacent healthy lung tissue, and control blood samples. Forty-five percent of nonsmall cell lung tumors harbored either intron or exon alterations. We identified R86G, F354L, Y272Y and three polymorphisms: 290+36G/T, 386+156G/T, and 862+145C/T (novel). R86G (novel) and F354L mutations were found in six squamous cell carcinomas and three large cell cancer carcinomas, but not in the adjacent healthy tissue or controls samples. The F354L mutation was found in advanced squamous cell carcinomas with elevated COX-2 expression, rare P53, and no K-RAS mutation. Results indicate that the LKB1 gene is changed in a certain proportion of nonsmall cell lung tumors, predominately in advanced squamous lung carcinoma. Inactivation of the gene takes place via the C-terminal domain and could be related to mechanisms influencing tumor initiation, differentiation, and metastasis.

Pleural mechanics and fluid exchange.

PubMed

Lai-Fook, Stephen J

The pleural space separating the lung and chest wall of mammals contains a small amount of liquid that lubricates the pleural surfaces during breathing. Recent studies have pointed to a conceptual understanding of the pleural space that is different from the one advocated some 30 years ago in this journal. The fundamental concept is that pleural surface pressure, the result of the opposing recoils of the lung and chest wall, is the major determinant of the pressure in the pleural liquid. Pleural liquid is not in hydrostatic equilibrium because the vertical gradient in pleural liquid pressure, determined by the vertical gradient in pleural surface pressure, does not equal the hydrostatic gradient. As a result, a viscous flow of pleural liquid occurs in the pleural space. Ventilatory and cardiogenic motions serve to redistribute pleural liquid and minimize contact between the pleural surfaces. Pleural liquid is a microvascular filtrate from parietal pleural capillaries in the chest wall. Homeostasis in pleural liquid volume is achieved by an adjustment of the pleural liquid thickness to the filtration rate that is matched by an outflow via lymphatic stomata.

Closed pleural biopsy was previously considered a procedure of choice in cases of undiagnosed pleural effusion with good efficacy. Currently, the closed pleural biopsy has been replaced by thoracoscopic biopsy but not easily available in resource-limited setups. The objective of this study was to analyze the diagnostic yield and safety of closed needle pleural biopsy in exudative pleural effusion and assessment of patients' characteristics with the yield of pleural biopsy. This was a cross-sectional study. This study was conducted at Institute of Respiratory Diseases, SMS Medical College, Jaipur, a tertiary care center of West India. A total of 250 cases of pleural effusion were evaluated with complete pleural fluid biochemical, microbiological, and cytological examination. Out of these 250 patients, 59 were excluded from the study as the diagnosis could be established on initial pleural fluid examination. The remaining (191) patients were considered for closed pleural biopsy with Abrams pleural biopsy needle. The main outcome measure was diagnostic yield in the form of confirming diagnosis. Out of the 191 patients with exudative lymphocytic pleural effusion, 123 (64.40%) were diagnosed on the first pleural biopsy. Among the remaining 68 patients, 22 patients had repeat pleural biopsy with a diagnostic yield of 59.9%. The overall pleural biopsy could establish the diagnosis in 136 (71.20%) patients with pleural effusion. The most common diagnosis on pleural biopsy was malignancy followed by tuberculosis. Closed pleural biopsy provides diagnostic yield nearly comparative to thoracoscopy in properly selected patients of pleural effusions. In view of good yield, low cost, easy availability, and very low complication rate, it should be used routinely in all cases of undiagnosed exudative lymphocytic pleural effusion. There was no comparison with a similar group undergoing thoracoscopic pleural biopsy.

Oral squamous cell carcinomas comprise a heterogeneous tumor cell population with varied molecular characteristics, which makes prognostication of these tumors a complex and challenging issue. Thus, molecular profiling of these tumors is advantageous for an accurate prognostication and treatment planning. This is a retrospective study on a cohort of primary locally advanced oral squamous cell carcinomas (n = 178) of an Indian rural population. The expression of EGFR, p53, cyclin D1, Bcl-2 and p16 in a cohort of primary locally advanced oral squamous cell carcinomas was evaluated. A potential biomarker that can predict the tumor response to treatment was identified. Formalin-fixed paraffin-embedded tumor blocks of (n = 178) of histopathologically diagnosed cases of locally advanced oral squamous cell carcinomas were selected. Tissue microarray blocks were constructed with 2 cores of 2 mm diameter from each tumor block. Four-micron-thick sections were cut from these tissue microarray blocks. These tissue microarray sections were immunohistochemically stained for EGFR, p53, Bcl-2, cyclin D1 and p16. In this cohort, EGFR was the most frequently expressed 150/178 (84%) biomarker of the cases. Kaplan-Meier analysis showed a significant association (p = 0.038) between expression of p53 and a poor prognosis. A Poisson regression analysis showed that tumors that expressed p53 had a two times greater chance of recurrence (unadjusted IRR-95% CI 2.08 (1.03, 4.5), adjusted IRR-2.29 (1.08, 4.8) compared with the tumors that did not express this biomarker. Molecular profiling of oral squamous cell carcinomas will enable us to categorize our patients into more realistic risk groups. With biologically guided tumor characterization, personalized treatment protocols can be designed for individual patients, which will improve the quality of life of these patients.

In the present study, human primary oral squamous carcinoma cells treated with cisplatin and 5-fluorouracil were analyzed, for the first time, by in vitro FTIR Microspectroscopy (FTIRM), to improve the knowledge on the biochemical pathways activated by these two chemotherapy drugs. To date, most of the studies regarding FTIRM cellular analysis have been executed on fixed cells from immortalized cell lines. FTIRM analysis performed on primary tumor cells under controlled hydrated conditions provides more reliable information on the biochemical processes occurring in in vivo tumor cells. This spectroscopic analysis allows to get on the same sample and at the same time an overview of the composition and structure of the most remarkable cellular components. In vitro FTIRM analysis of primary oral squamous carcinoma cells evidenced a time-dependent drug-specific cellular response, also including apoptosis triggering. Furthermore, the univariate and multivariate analyses of IR data evidenced meaningful spectroscopic differences ascribable to alterations affecting cellular proteins, lipids and nucleic acids. These findings suggest for the two drugs different pathways and extents of cellular damage, not provided by conventional cell-based assays (MTT assay and image-based cytometry).

Malignant pleural effusion (MPE) is due tumor which arises from the mesothelium or metastases from tumor origniating other sites. Generally, the prognosis of MPE is poor, in the premise of reducing the pain of patients, as soon as possible make clear the property of pleural effusion and cause of the disesease, rightly and quickly, providing effective information for subsequent treatment. The cell block of 103 patients by using natural sedimentation or plasma coagulation method combined with HE staining and immunohistochemical staining method maked clear diagnosis and compared with other methods. 90 patients were diagnosed by cell block section from 103 patients who had MPE (diagnostic rate 87.4%); 32 cases were diagnosed by cell block section only, 74 cases pointed out that the pathological type , 23 cases even pointed out the primary lesions; 71 cases examined other invasive methods at the same time, the diagnostic rate was 87.3% and 81.7%; the detection rate of cell block section and cytological smear in detecting malignant tumor cells was 86.7%and 44.0% respectively. Cell block can not only increase the diagnosis, in contrast to cytological smear, and own the same diagnostic rate compared with other invasive methods, but also can confirm pathological type and primary lesion; especially, for other invasive methods, cell block method is a preferable complementary method, and that cell block method maybe the only way for some patients.

Pancreatic ductal adenocarcinoma has limited treatment options. There is an urgent need for developing appropriate pre-clinical models recapitulating metastatic disease, the most common clinical scenario at presentation. Ascites accumulation occurs in up to 20–30% of patients with pancreatic cancer; this milieu represents a highly cellular research resource of metastatic peritoneal spread. In this study, we utilized pancreatic ascites/pleural effusion cancer cells to establish patient derived xenografts. Ascites/pleural effusion-patient derived xenografts were established from twelve independent cases. Xenografts were serially passed in nude mice and tissue bio-specimen banking has been established. Histopathology of emergent tumors demonstrates poorly to moderately differentiated, glandular and mucin producing tumors, mirroring morphology of primary pancreatic cancer tumors. Whole genome sequencing of six patient derived xenografts samples demonstrates common mutations and structural variations similar to those reported in primary pancreatic cancer. Xenograft tumors were dissociated to single-cells and in-vitro drug sensitivity screen assays demonstrated chemo-resistance, correlating with patient clinical scenarios, thus serving as a platform for clinically relevant translational research. Therefore, establishment of this novel ascites/pleural effusion patient derived xenograft model, with extensive histopathology and genomic characterization, opens an opportunity for the study of advanced aggressive pancreatic cancer. Characterization of metastatic disease and mechanisms of resistance to therapeutics may lead to the development of novel drug combinations. PMID:28489577

A 79-year-old woman who had a past history of chronic renal failure 10 years earlier, tongue cancer (T2N2M0) 3 years earlier, and tuberculosis of the cervical lymph nodes 6 months earlier was suddenly admitted with the complaint of right chest pain on April 6, 2004. Right pneumothorax and mild pleural effusion were observed on a chest radiograph. There was no improvement in the patients collapsed lung despite the insertion of a chest drainage tube into the pleural cavity. Three thin-walled cavitary lesions were noted in the right lobe of segment 1 on computed tomography, and the cause of her pneumothorax was thought to be air leakage from the largest cavitary lesion adjacent to the visceral pleura. Partial resection of the right lung by video-assisted thoracoscopic surgery (VATS) was performed at the Department of Thoracic Surgery. Subsequently, it was determined that metastatic squamous cell carcinoma of the lung, corresponding to her tongue cancer, had invaded the visceral pleura adjacent to the largest cavitary lesion. Simultaneously, an epitheloid granuloma with caseating necrosis was observed adjacent to a partially thickened portion of this cavitary lesion. The epitheloid granuloma was found to be acid-fast bacilli-positive and a diagnosis of Mycobacterium tuberculosis pulmonary tuberculosis was made. We report a rare case of the coexistence of metastatic lung cancer originating from tongue cancer and active pulmonary tuberculosis diagnosed in the same large cavitary lesion.

The Cancer of RESpiratory Tract (CREST) biorepository was established to investigate biological mechanisms and to develop tools and strategies for primary and secondary prevention of respiratory tract cancer. The CREST biorepository is focused on pleural malignant mesothelioma, a rare and severe cancer linked to asbestos exposure whose incidence is particularly high in the Ligurian region. The CREST biorepository includes biological specimens from (a) patients with pleural malignant mesothelioma and lung cancer, (b) patients with nonneoplastic respiratory conditions, and (c) control subjects. Whole blood, plasma, serum, lymphocytes, pleural fluid, saliva, and biopsies are collected, and a questionnaire is administered. Collection, transportation, and storage are done according to international standards. As of January 31, 2008, the overall number of subjects recruited was 1,590 (446 lung cancer, 209 pleural malignant mesothelioma, and 935 controls). The biorepository includes a total of 10,055 aliquots (4,741 serum; 3,082 plasma; 1,599 whole blood; 633 pleural fluid; and 561 lymphocytes) and 107 biopsies. Demographic, clinical, and epidemiologic information is collected for each subject and processed in a dedicated database. The CREST biorepository is a valuable tool for molecular epidemiology and translational studies. This structure relies on a network of contacts with local health districts that allows for an active search for patients. This is a particularly efficient approach, especially when the object of the study is a rare cancer type. The CREST experience suggests that the presence of limited resources can be overcome by the biorepository specialization, the high quality of the epidemiologic information, and the variety of samples.

Pleurodesis performed either by pleurectomy or pleural abrasion is recommended in the approach to primary spontaneous pneumothorax to avoid recurrence. However, the efficacy of parietal pleural abrasion in producing pleurodesis is questioned. This study aims to determine the efficacy of apical abrasion alone, abrasion plus fibrin sealant application, and pleurectomy in producing pleurodesis in rabbits. Rabbits were subjected to video-assisted thoracic surgery alone (control) or to video-assisted thoracic surgery with apical gauze abrasion, abrasion plus fibrin sealant instillation, or apical pleurectomy. Blood samples were collected preoperatively and 48 h and 28 days postoperatively to measure total leukocytes (white blood cell count), neutrophil counts, and serum interleukin (IL)-8 levels. After 28 days the animals were sacrificed for macroscopic evaluation of the degree of apical pleurodesis and microscopic evaluation of local pleural fibrosis and collagen deposition. White blood cell and neutrophil counts were similar in all groups, whereas the serum IL-8 level peaked at 48 h in all groups and decreased after 28 days, except in the pleurectomy group. After 28 days the abrasion plus fibrin sealant and pleurectomy groups had significantly more pleural adhesions, pleural fibrosis, and collagen deposition than the abrasion alone group, mainly due to thick mature fibers. Abrasion with local fibrin sealant instillation is as effective as pleurectomy in producing pleurodesis in rabbits. Apical pleurectomy elicits a more persistent elevation of serum IL-8 levels than apical abrasion alone or abrasion plus fibrin adhesive instillation.

Squamous cell carcinoma (SCC) is a malignant tumor of epithelium that shows squamous cell differentiation. It is the second most common cancer of the skin and usually occurs in areas exposed to the sun but it can rarely arise within the conjunctival epithelium with a deep component. We describe a woman with a history of chronic blepharoconjunctivitis unresponsive to topical medications. Examination disclosed a hyperaemic translucent patch with blurred margins of the upper palpebral conjunctiva. Tarsoconjunctival biopsy revealed intraepithelial squamous cell carcinoma. Management consisted of complete tumor excision with removal of the entire posterior lamella of the left upper eyelid and reconstruction. Histopathologic analysis confirmed primary squamous cell carcinoma arising from conjunctival epithelium, involving the underlying tarsus. Patients with unexplained chronic unilateral blepharoconjunctivitis or papillary hypertrophy of the palpebral conjunctiva should be considered for biopsy to rule out neoplasia, even when there is no sign of an evident mass.

BACKGROUND: Noninvasive diagnosis of pleural tuberculosis (TB) remains a challenge due to the paucibacillary nature of the disease. As Mycobacterium tuberculosis (MTB)-specific T cells are recruited into pleural space in TB effusion; their indirect detection may provide useful clinical information. OBJECTIVES: Evaluation of pleural fluid interferon (INF)-γ levels vs Quantiferon–TB Gold In tube assay (QFT- IT) in blood and its adapted variants, using pleural fluid or isolated pleural fluid cells in the diagnosis of pleural TB. METHODS: Thirty-eight patients with pleural effusion of unknown etiology presented at Assiut University Hospital, Egypt, were recruited. Blood and pleural fluid were collected at presentation for INF-γ assays. Ex vivo pleural fluid INF-γ levels, QFT-IT in blood and its adapted variants were compared with final diagnosis as confirmed by other tools including blind and/or thoracoscopic pleural biopsy. RESULTS: The final clinical diagnosis was TB in 20 (53%), malignancy in 10 (26%), and effusion due to other causes in eight patients (21%). Ex vivo pleural fluid INF-γ levels accurately identified TB in all patients and were superior to the QFT-IT assays using blood or pleural fluid (70 and 78% sensitivity, with 60 and 83% specificity, respectively). QFT-IT assay applied to isolated pleural fluid cells had 100% sensitivity and 72% specificity. The optimal cut-off obtained with ROC analysis was 0.73 for TB Gold assay in blood assay, 0.82 IU/ml for the cultured pleural fluid assay, and 0.94 for isolated pleural cells assay. CONCLUSION: The ex vivo pleural fluid INF-γ level is an accurate marker for the diagnosis of pleural TB. QFT- IT assay in peripheral blood or its adapted versions of the assay using pleural fluid and/or washed pleural fluid cells had no diagnostic advantage over pleural fluid INF-γ in the diagnosis of pleural TB.

Diagnostic imaging of small amounts of pleural fluid: pleural effusion vs. physiologic pleural fluid.

PubMed

Kocijancic, Igor

2007-12-01

The aim of this article is to present an overview of our 10 years clinical research work and early clinical experience with small pleural effusions. Small amounts of pleural fluid are severely difficult to identify with imaging methods (chest x-rays and ultrasound). Nevertheless, it may be an important finding, sometimes leading to a definitive diagnosis of pleural carcinomatosis, infection or other pathologic condition. Chest x-rays were used for many years for the diagnosis of small pleural effusions. Lateral decubitus chest radiographs represented a gold standard for imaging of small amounts of plural fluid for more than 80 years. In the last two decades, ultrasonography of pleural space became a leading real-time method for demonstrating small pleural effusions. Furthermore, the advent of sonographic technology actually enables detection of physiologic pleural fluid in some otherwise healthy individuals. In conclusion, new definitions of the key terms in the field of diagnostic imaging of small amounts of pleural fluid seem to be justified. We suggest that the term pleural fluid should determine physiologic pleural space condition while the term pleural effusion should only be used in the cases of pleural involvement or pleural illness.

Diagnostic Tools of Pleural Effusion

PubMed Central

2014-01-01

Pleural effusion is not a rare disease in Korea. The diagnosis of pleural effusion is very difficult, even though the patients often complain of typical symptoms indicating of pleural diseases. Pleural effusion is characterized by the pleural cavity filled with transudative or exudative pleural fluids, and it is developed by various etiologies. The presence of pleural effusion can be confirmed by radiological studies including simple chest radiography, ultrasonography, or computed tomography. Identifying the causes of pleural effusions by pleural fluid analysis is essential for proper treatments. This review article provides information on the diagnostic approaches of pleural effusions and further suggested ways to confirm their various etiologies, by using the most recent journals for references.

Purpose: To evaluate late cardiopulmonary toxicities after concurrent chemoradiotherapy (CCRT) for esophageal carcinomas. Methods and Materials: From February 2002 through April 2005, 74 patients with clinical Stage I-IVB carcinoma of the esophagus were treated with CCRT. Sixty-nine patients with thoracic squamous cell carcinoma were the core of this analysis. Patients received 60 Gy of radiation therapy in 30 fractions over 8 weeks, including a 2-week break, and received 2 cycles of fluorouracil/cisplatin chemotherapy concomitantly. Initial radiation fields included primary tumors, metastatic lymph nodes, and supraclavicular, mediastinal, and celiac nodes areas. Late toxicities were assessed with the late radiation morbidity scoringmore » scheme of the Radiation Therapy Oncology Group/European Organiation for Research and Treatment of Cancer. Results: The median age was 67 years (range, 45-83 years). The median follow-up time was 26.1 months for all patients and 51.4 months for patients still alive at the time of analysis. Five cardiopulmonary toxic events of Grade 3 or greater were observed in 4 patients, Grade 5 heart failure and Grade 3 pericarditis in 1 patient, and Grade 3 myocardial infarction, Grade 3 radiation pneumonitis, and Grade 3 pleural effusion. The 2-year cumulative incidence of late cardiopulmonary toxicities of Grade 3 or greater for patients 75 years or older was 29% compared with 3% for younger patients (p = 0.005). Conclusion: The CCRT used in this study with an extensive radiation field is acceptable for younger patients but is not tolerated by patients older than 75 years.« less

The basics of pleural liquid dynamics are summarized. The normal pleural cavity contains a small amount of pleural liquid (0.1-0.3 ml/kg). Its protein concentration is about 1.0 g/dl and its pH is 7.6. The normal flow of pleural liquid is gravity dependent, and pleural liquid flows from the costal to the mediastinal region. In experimental hydrothorax, the pleural liquid was removed mainly via lymphatics. The turnover of the pleural liquid is rapid, and it depends on the area of contact between pleural liquid and pleural and on the blood flow to the pleura.

Diagnosis of pleural tuberculosis (TB) using routinely available diagnostic methods is challenging due to the paucibacillary nature of the disease. Histopathology and pleural tissue TB culture involves an invasive procedure which requires expertise and appropriate equipment, both often unavailable in many health units. Xpert MTB/Rif test has been widely evaluated in sputum specimens but data on its performance in pleural TB is scarce. We evaluated the accuracy of Cepheid's Xpert MTB/Rif test on pleural fluid in the diagnosis of pleural TB in Uganda. Consenting adult patients with exudative pleural effusions underwent pleural biopsy and the tissue obtained subjected to Lowenstein-Jensen and mycobacterial growth indicator tube MTB cultures and histopathology. Pleural fluid for Xpert MTB/Rif testing was also collected. Data on socio-demographic characteristics, clinical symptoms, HIV status and CD4 count were also collected. Sensitivity, specificity, positive and negative predictive values of Xpert MTB/Rif test on pleural fluid in pleural TB diagnosis were calculated using pleural tissue MTB culture and/or histopathology as the reference standard. Of the 116 participants [female 50%, mean age 34 (SD ±13], 87/116 (75%) had pleural TB confirmed on pleural tissue culture and/or histopathology. The Xpert MTB/Rif test identified 25 (28.7%) of the 87 confirmed pleural TB cases. The sensitivity and specificity of Xpert MTB/Rif test were 28.7% and 96.6% respectively while the positive and negative predictive values were 96.1% and 31.1% respectively. Xpert MTB/Rif test on pleural fluid does not accurately diagnose pleural TB and therefore cannot be used as an initial evaluation test in patients with suspected pleural TB. New, rapid and accurate tests for the diagnosis of pleural TB are still warranted.

To study the factors related to the development of residual pleural thickening in pleural tuberculosis. We studied 39 patients with tuberculous pleural effusion. A chest X-ray was taken of each patient at the end of treatment. The patients' medical histories, pleural fluid findings and diagnostic chest films were evaluated. Residual pleural thickening was defined as thickening that was visibly greater than 2 mm in the lower side portion of the chest film. Residual pleural thickening developed in 26% of patients and was found mainly in men (RR = 3.86). In no patients with Löwenstein-Jensen cultures positive for Mycobacterium tuberculosis did pleural complications develop. Residual pleural thickening is a common complication of tuberculous pleural effusion. Residual pleural thickening in tuberculous pleurisy occurs more often in men and older patients, and in cases in which pleural liquid culture is negative for M. tuberculosis.

Closed pleural biopsy (CPB) in patients with malignant pleural effusion is less sensitive than cytology. Ultrasound-assisted CPB allows biopsies to be performed in the lower thoracic parietal pleura, where secondary spread from pleural metastases is initially more likely to be found. We analyzed whether choosing the point of entry for CPB with thoracic ultrasound assistance influences the diagnostic yield in malignant pleural effusion. This prospective study included patients who underwent CPB performed by an experienced pulmonologist in 2008-2010 (group A) and thoracic ultrasound was used to select the biopsy site. The results were compared with a historical series of CPB performed by the same pulmonologist without the assistance of thoracic ultrasound (group B). An Abrams needle was used in all cases. We analyzed the obtaining of pleural tissue and the diagnostic yield. We included 114 CPBs from group A (23% tuberculous pleural effusion, 27% malignant pleural effusion) and 67 CPBs from group B (24% tuberculous pleural effusion, 30% malignant pleural effusion) (P = .70). Pleural tissue was obtained in 96.5% of the group A CPBs and 89.6% of the group B CPBs (P = .05). The diagnostic yields of CPB for tuberculous pleural effusion and malignant pleural effusion in group A were 89.5% and 77.4%, respectively, and 91.7% and 60%, respectively, in group B (P = .80 for tuberculous pleural effusion, and P = .18 for malignant pleural effusion). Selecting the point of entry for CPB using thoracic ultrasound increases the likelihood of obtaining pleural tissue and the diagnostic yield, but without statistical significance. We recommend ultrasound-assisted CPB to investigate pleural effusion, since the diagnostic yield of a pleural biopsy with an Abrams needle increased by > 17% in subjects with malignant pleural effusion.

Theories elucidating pleural pressures should explain all observations including the equal and opposite recoil of the chest wall and lungs, the less than expected pleural hydrostatic gradient and its variation at lobar margins, why pleural pressures are negative and how pleural fluid circulation functions. A theoretical model describing equilibrium between buoyancy, hydrostatic forces, and capillary forces is proposed. The capillary equilibrium model described depends on control of pleural fluid volume and protein content, powered by an active pleural pump. The interaction between buoyancy forces, hydrostatic pressure and capillary pressure was calculated, and values for pleural thickness and pressure were determined using values for surface tension, contact angle, pleural fluid and lung densities found in the literature. Modelling can explain the issue of the differing hydrostatic vertical pleural pressure gradient at the lobar margins for buoyancy forces between the pleural fluid and the lung floating in the pleural fluid according to Archimedes' hydrostatic paradox. The capillary equilibrium model satisfies all salient requirements for a pleural pressure model, with negative pressures maximal at the apex, equal and opposite forces in the lung and chest wall, and circulatory pump action. This model predicts that pleural effusions cannot occur in emphysema unless concomitant heart failure increases lung density. This model also explains how the non-confluence of the lung with the chest wall (e.g., lobar margins) makes the pleural pressure more negative, and why pleural pressures would be higher after an upper lobectomy compared to a lower lobectomy. Pathological changes in pleural fluid composition and lung density alter the equilibrium between capillarity and buoyancy hydrostatic pressure to promote pleural effusion formation.

Photochemical Internalization is a novel drug delivery technology for cancer treatment based on the principle of Photodynamic Treatment. Using a photosensitizer that locates in endocytic vesicles membranes of tumor cells, Photochemical internalization enables cytosolic release of endocytosed antitumor agents in a site-specific manner. The purpose of the present in-vitro study was to explore whether Photochemical Internalization is able to enhance the efficacy of Ranpirnase, a cytotoxic amphibian ribonuclease, for eradication of squamous cell carcinoma of the head and neck. Cell viability was measured in 8 primary human cell lines of squamous cell carcinoma of the head and neck after treatment with Ranpirnase and Photochemical Internalization. For Photochemical Internalization the photosensitizer disulfonated tetraphenyl porphine was incubated with tumor cells followed by exposure to blue light (435 nm). Our study demonstrates significant enhancement of antitumor activity of Ranpirnase by Photochemical Internalization. Treatment responses were heterogeneous between the primary cancer cell lines. Combining Photochemical Internalization with Ranpirnase resulted in 4.6 to 1,940-fold increased cytotoxicity when compared with the ribonuclease alone (P < 0.05). Cytotoxicity of Ranpirnase can be markedly enhanced by Photochemical Internalization in squamous cell carcinoma of the head and neck.

To report three cases of primary squamous cell carcinoma of the breast with an unusual "basal-HER2" phenotype. Clinical data were analyzed. Morphological features were observed. Immunohistochemical study for ER, PR, HER2, Ki-67, CK 5/6, CK10/13, CK14, EGFR, P63 and FISH detection of HER2 gene amplification were performed. Three patients were all female with 26, 57 and 66 years old. The tumors were 3 cm, 4 cm and 5 cm in size respectively. Morphologically, all three tumors were pure squamous cell carcinoma and entirely composed metaplastic squamous cells. Two tumors were moderately differentiated and one was poorly differentiated. All three patients were positive for P63 or CK10/13. All three tumors exhibited basal-HER2 phenotype: negative for ER and PR, positive for HER2 protein and HER2 gene amplification, and positive for at least two basal markers. SCC with basal-HER2 phenotype is an extremely rare subset of breast carcinoma. Since it may have worse prognosis than typical basal-like SCC, recognization of this unusual SCC in routine work may have obvious clinical significance.

Background Some trials recently demonstrated the benefit of targeted treatment for malignant disease; therefore, adequate tissues are needed to detect the targeted gene. Pleural biopsy using flex-rigid pleuroscopy and pleural effusion cell block analysis are both useful for diagnosis of malignancy and obtaining adequate samples. The purpose of our study was to compare the diagnostic utility between the two methods among patients with malignant pleural disease with effusion. Methods Data from patients who underwent flex-rigid pleuroscopy for diagnosis of pleural effusion suspicious for malignancy at the National Cancer Center Hospital, Japan between April 2011 and June 2014 were retrospectively reviewed. All procedures were performed under local anesthesia. At least 150 mL of pleural fluid was collected by pleuroscopy, followed by pleural biopsies from the abnormal site. Results Thirty-five patients who were finally diagnosed as malignant pleural disease were included in this study. Final diagnoses of malignancy were 24 adenocarcinoma, 1 combined adeno-small cell carcinoma, and 7 malignant pleural mesothelioma (MPM), and 3 metastatic breast cancer. The diagnostic yield was significantly higher by pleural biopsy than by cell block [94.2% (33/35) vs. 71.4% (25/35); p = 0.008]. All patients with positive results on cell block also had positive results on pleural biopsy. Eight patients with negative results on cell block had positive results on pleural biopsy (lung adenocarcinoma in 4, sarcomatoid MPM in 3, and metastatic breast cancer in 1). Two patients with negative results on both cell block and pleural biopsy were diagnosed was sarcomatoid MPM by computed tomography-guided needle biopsy and epithelioid MPM by autopsy. Conclusion Pleural biopsy using flex-rigid pleuroscopy was efficient in the diagnosis of malignant pleural diseases. Flex-rigid pleuroscopy with pleural biopsy and pleural effusion cell block analysis should be considered as the initial diagnostic approach for malignant pleural diseases presenting with effusion.

A 26-year-old male was hospitalized with fever and pharyngeal pain. Liver dysfunction and an increase in the percentage of atypical lymphocytes in the peripheral blood were detected. Computed tomography showed pneumonia involving the right lung and synpneumonic pleural effusion. Serum immunological tests showed positive results for Epstein-Barr virus (EBV) viral capsid antigen (VCA) IgM and IgG antibodies and Chlamydophila (Chlamydia) pneumoniae (C. pneumoniae) IgM and IgA antibodies on admission. The pneumonia and pleural effusion were no longer detectable after a week of treatment with starting azithromycin. At 7 weeks after admission, the liver function test results returned to within normal limits, the serum became negative for EBV VCA IgM antibody, the C. pneumoniae IgM antibody titer decreased, and the C. pneumoniae IgA and IgG antibody titers increased. This case was suspected to have infectious mononucleosis caused by primary coinfection with C. pneumoniae and EBV.

Previous studies have revealed that patients with oral or esophageal cancer are at higher risk for subsequently developing a second primary malignancy. However, it remains to be determined what association exists between oral cancer and esophageal cancer particularly in Asian countries where squamous cell carcinoma is the predominant type of esophageal cancer. A population-based study was carried out in Taiwan, where the incidence rates of both oral and esophageal squamous cell carcinomas are high, to test the hypothesis that oral cancer or esophageal cancer predisposes an individual to developing the other form of cancer. Our results showed that patients with primary oral cancer (n=45,859) had ten times the risk of second esophageal cancer compared to the general population. Within the same cohort, the reciprocal risk of oral cancer as a second primary in primary esophageal cancer patients (n=16,658) was also increased seven-fold. The bidirectional relationship suggests common risk factors between these two cancers. The present study is not only the first population-based study in Asia to validate the reciprocal relationship between oral and esophageal squamous cell carcinomas, but also will aid in the appropriate selection of high-risk patients for a future follow-up surveillance program.

Previous studies have revealed that patients with oral or esophageal cancer are at higher risk for subsequently developing a second primary malignancy. However, it remains to be determined what association exists between oral cancer and esophageal cancer particularly in Asian countries where squamous cell carcinoma is the predominant type of esophageal cancer. A population-based study was carried out in Taiwan, where the incidence rates of both oral and esophageal squamous cell carcinomas are high, to test the hypothesis that oral cancer or esophageal cancer predisposes an individual to developing the other form of cancer. Our results showed that patients with primary oral cancer (n=45,859) had ten times the risk of second esophageal cancer compared to the general population. Within the same cohort, the reciprocal risk of oral cancer as a second primary in primary esophageal cancer patients (n=16,658) was also increased seven-fold. The bidirectional relationship suggests common risk factors between these two cancers. The present study is not only the first population-based study in Asia to validate the reciprocal relationship between oral and esophageal squamous cell carcinomas, but also will aid in the appropriate selection of high-risk patients for a future follow-up surveillance program.

Subatmospheric pleural pressure (Ppl), which is approximately -3 to -5 cmH 2 O at functional residual capacity (FRC) makes pleura a unique organ in the human body. The negative Ppl is critical for maintaining the lungs in a properly inflated state and for proper blood circulation within the thorax. Significant and sudden pleural pressure changes associated with major pleural pathologies, as well as therapeutic interventions may be associated with life-threatening complications. The pleural pressure may show two different values depending on the measurement method applied. These are called pleural liquid pressure and pleural surface pressure. It should also be realized that there are significant differences in pleural pressure distribution in pneumothorax and pleural effusion. In pneumothorax, the pressure is the same throughout the pleural space, while in pleural effusion there is a vertical gradient of approximately 1 cm H 2 O/cm in the pleural pressure associated with the hydrostatic pressure of the fluid column. Currently, two main methods of pleural pressure measurement are used: simple water manometers and electronic systems. The water manometers are conceptually simple, cheap and user-friendly but they only allow the estimation of the mean values of pleural pressure. The electronic systems for pleural pressure measurement are based on pressure transducers. Their major advantages include precise measurements of instantaneous pleural pressure and the ability to display and to store a large amount of data. The paper presents principles and details of pleural pressure measurement as well as the rationale for its use. Copyright © 2018 Elsevier Ltd. All rights reserved.

Pleural thickenings can be caused by asbestos exposure and may evolve into malignant pleural mesothelioma. While an early diagnosis plays the key role to an early treatment, and therefore helping to reduce morbidity, the growth rate of a pleural thickening can be in turn essential evidence to an early diagnosis of the pleural mesothelioma. The detection of pleural thickenings is today done by a visual inspection of CT data, which is time-consuming and underlies the physician's subjective judgment. Computer-assisted diagnosis systems to automatically assess pleural mesothelioma have been reported worldwide. But in this paper, an image analysis pipeline to automatically detect pleural thickenings and measure their volume is described. We first delineate automatically the pleural contour in the CT images. An adaptive surface-base smoothing technique is then applied to the pleural contours to identify all potential thickenings. A following tissue-specific topology-oriented detection based on a probabilistic Hounsfield Unit model of pleural plaques specify then the genuine pleural thickenings among them. The assessment of the detected pleural thickenings is based on the volumetry of the 3D model, created by mesh construction algorithm followed by Laplace-Beltrami eigenfunction expansion surface smoothing technique. Finally, the spatiotemporal matching of pleural thickenings from consecutive CT data is carried out based on the semi-automatic lung registration towards the assessment of its growth rate. With these methods, a new computer-assisted diagnosis system is presented in order to assure a precise and reproducible assessment of pleural thickenings towards the diagnosis of the pleural mesothelioma in its early stage.

Over 1.5 million pleural effusions occur in the United States every year as a consequence of a variety of inflammatory, infectious, and malignant conditions. Although rarely fatal in isolation, pleural effusions are often a marker of a serious underlying medical condition and contribute to significant patient morbidity, quality-of-life reduction, and mortality. Pleural effusion management centers on pleural fluid drainage to relieve symptoms and to investigate pleural fluid accumulation etiology. Many recent studies have demonstrated important advances in pleural disease management approaches for a variety of pleural fluid etiologies, including malignant pleural effusion, complicated parapneumonic effusion and empyema, and chest tube size. The last decade has seen greater implementation of real-time imaging assistance for pleural effusion management and increasing use of smaller bore percutaneous chest tubes. This article will briefly review recent pleural effusion management literature and update the latest changes in common procedural terminology billing codes as reflected in the changing landscape of imaging use and percutaneous approaches to pleural disease management.

Discordance in estrogen receptor alpha (ERα), progesterone receptor (PR), androgen receptor (AR) and human epidermal growth factor receptor 2 (HER2) status between primary breast cancers and solid distant metastases (“conversion”) has been reported previously. Even though metastatic spread to the peritoneal and pleural cavities occurs frequently and is associated with high mortality, the rate of receptor conversion and the prognostic implications thereof remain elusive. We therefore determined receptor conversion in 91 effusion metastases (78 pleural, 13 peritoneal effusions) of 69 patients by immunohistochemistry (IHC) and in situ hybridization. Data were coupled to clinical variables and treatment history. ERα, PR and AR receptor status converted from positive in the primary tumor to negative in the effusion metastases or vice versa in 25-30%, 30-35% and 46-51% of cases for the 1% and 10% thresholds for positivity, respectively. 19-25% of patients converted clinically relevant from “ERα+ or PR+” to ERα-/PR- and 3-4% from ERα-/PR- to “ERα+ or PR+”. For HER2, conversion was observed in 6% of cases. Importantly, receptor conversion for ERα (p = 0.058) and AR (p < 0.001) was more often seen in patients adjuvantly treated with endocrine therapy. Analogous to this observation, HER2-loss was more frequent in patients adjuvantly treated with trastuzumab (p < 0.001). Alike solid distant metastases, receptor conversion for ERα, PR, AR and HER2 is a frequent phenomenon in peritoneal and pleural effusion metastases. Adjuvant endocrine and trastuzumab therapy imposes an evolutionary selection pressure on the tumor, leading to receptor loss in effusion metastases. Determination of receptor status in malignant effusion specimens will facilitate endocrine treatment decision-making at this lethal state of the disease, and is hence recommended whenever possible.

OBJECTIVES: To evaluate the effectiveness and safety of pleurodesis carried out entirely on an outpatient basis in patients with recurrent malignant pleural effusions and Karnofsky Performance Status scores ≤70. METHODS: This study was a prospective trial comprising patients with symptomatic recurrent malignant pleural effusion and Karnofsky Performance Status scores ≤70 but >30. All selected patients underwent pleural catheter placement (14 Fr) in an outpatient facility. When chest radiography revealed post‐drainage lung expansion of >90%, pleurodesis (3 g of talc) was performed. Catheters were maintained until the daily output was <100 mL/day. The patients were evaluated in the first month and every three months thereafter for fluid recurrence, the need for additional procedures, and complications. RESULTS: During the study period (January 2005 to July 2007), 64 patients (24 men, 40 women), with an average age of 61.4 years, underwent elective chest tube drainage. Primary sites of the underlying malignancy were breast (27), lung (22), and others (15). Sixty‐six pleural catheters were placed (bilaterally in 2 patients), and 52 talc pleurodesis procedures were performed. Fourteen patients had a trapped lung and were excluded from the trial. No complications were observed during catheter placement or pleurodesis. Post‐pleurodesis complications included catheter obstruction (4 patients) and empyema (1). The average drainage time was 9.9 days. The recurrence rate observed in patients that were alive 30 days after pleurodesis was 13.9% (5/36 patients). Six patients required additional procedures after the pleurodesis. The average survival time was 101 days. CONCLUSION: In this study, talc pleurodesis was safely performed in an outpatient setting with good efficacy and a reasonable complication rate, thereby avoiding hospital admission. PMID:21484035

Primary surgery is the preferred treatment of T1-T4a sinonasal squamous cell carcinoma (SNSCC). Patients with SNSCC in the National Cancer Data Base (NCDB) were analyzed. Factors that contributed to selecting primary surgical treatment were examined. Overall survival (OS) in surgical patients was analyzed. Four-thousand seven hundred and seventy patients with SNSCC were included. In T1-T4a tumors, lymph node metastases, maxillary sinus location, and treatment at high-volume centers were associated with selecting primary surgery. When primary surgery was utilized, tumor factors and positive margin guided worse OS. Adjuvant therapy improved OS in positive margin resection and advanced T stage cases. Tumor and non-tumor factors are associated with selecting surgery for the treatment of SNSCC. When surgery is selected, tumor factors drive OS. Negative margin resection should be the goal of a primary surgical approach. When a positive margin resection ensues, adjuvant therapy may improve OS. © 2017 Wiley Periodicals, Inc.

Pleural tuberculosis (TB), a form of extrapulmonary TB, can be difficult to diagnose. High numbers of lymphocytes in pleural fluid have been considered part of the diagnostic criteria for pleural TB; however, in many cases, neutrophils rather than lymphocytes are the predominant cell type in pleural effusions, making diagnosis more complicated. Additionally, there is limited information on the clinical and laboratory characteristics of neutrophil-predominant pleural effusions caused by Mycobacterium tuberculosis (MTB). To investigate clinical and laboratory differences between lymphocyte- and neutrophil-predominant pleural TB, we retrospectively analyzed 200 patients with the two types of pleural TB. Of these patients, 9.5% had neutrophil-predominant pleural TB. Patients with lymphocyte-predominant and neutrophil-predominant pleural TB showed similar clinical signs and symptoms. However, neutrophil-predominant pleural TB was associated with significantly higher inflammatory serum markers, such as white blood cell count (P = 0.001) and C-reactive protein (P = 0.001). Moreover, MTB was more frequently detected in the pleural fluid from patients in the neutrophil-predominant group than the lymphocyte-predominant group, with the former group exhibiting significantly higher rates of positive results for acid-fast bacilli in sputum (36.8 versus 9.4%, P = 0.003), diagnostic yield of MTB culture (78.9% versus 22.7%, P < 0.001) and MTB detected by polymerase chain reaction (31.6% versus 5.0%, P = 0.001). Four of seven patients with repeated pleural fluid analyses revealed persistent neutrophil-predominant features, which does not support the traditional viewpoint that neutrophil-predominant pleural TB is a temporary form that rapidly develops into lymphocyte-predominant pleural TB. In conclusion, neutrophil-predominant pleural TB showed a more intense inflammatory response and a higher positive rate in microbiological testing compared to lymphocyte-predominant pleural TB. Pleural TB should be considered in neutrophil-predominant pleural effusions, and microbiological tests are warranted. PMID:27788218

In contrast to the usefulness of thyroid transcription factor-1 (TTF-1) in distinguishing primary adenocarcinoma of the lung from metastatic lesions, TTF-1 expression in pulmonary squamous cell carcinoma is reported to be at low level and not a suitable immunohistochemical marker. We hypothesized that the highly sensitive detection system, CSA-II, can visualize even faint expression of TTF-1 in pulmonary squamous cell carcinoma. In this study, 2 commercially available clones of TTF-1 monoclonal antibody, 8G7G3/1 and SPT24, were used for staining 38 cases of pulmonary squamous cell carcinoma, in combination with the CSA-II and the conventional detection system, EnVision. The combined use of the 8G7G3/1 clone with EnVision and CSA-II showed a positive reaction in only 1 and 4 cases, respectively. The use of SPT24 clone showed positive staining in 5 cases with EnVision and in 20 of 38 cases (52.6%) with the CSA-II. Interestingly, positive staining by the SPT24-CSA-II technique of samples from tissue blocks preserved for <2 years was 73.6% compared with only 31.5% in those preserved for >2 years. In addition, a 6-month preservation of the cut sections resulted in stain fading and decreased positivity (50%), compared with freshly cut sections. We conclude that the use of the SPT24 monoclonal antibody with the CSA-II system can detect even weak expression of TTF-1 in pulmonary squamous cell carcinoma. This staining technique can potentially allow the discrimination of primary squamous cell carcinoma of the lung from metastatic lesions, especially in freshly prepared paraffin sections.

Chemotherapy regimens are often a 2-drug regimen in concurrent chemotherapy and radiotherapy for esophageal cancer (EC). However, some retrospective studies have suggested that for patients with EC receiving radiotherapy combined with 2-drug chemotherapy have the severe toxicity. And S-1 alone with the combination of radiotherapy treatment effect is good, and achieved good clinical remission rate. The purpose of this trial is compare the efficacy and toxicity of combining S-1 or S-1 plus cisplatin with radiotherapy for esophageal squamous cell carcinoma. The study is a randomized, controlled, multicenter trial, comparing S-1 versus S-1 plus cisplatin concurrent radiotherapy for patients with esophageal squamous cell carcinoma. Eighty-eight patients with unresectable or medically unfit for surgery esophageal squamous cell carcinoma (clinical stage I to III), will randomly assigned to receive four cycles (2 concomitant and 2 postradiotherapy) S-1 or S-1 plus cisplatin along with radiotherapy 60-66 Gy/30 to 33 fractions. The primary outcome is complete response rate of primary tumor which will be measured by endoscopy and computer screen at 3 months after the completion of treatment. Secondary outcomes include survival and toxicity. To our knowledge, this study protocol is the first to test the effect between S-1 versus S-1 plus cisplatin concurrent intensity modulated radiation therapy in the treatment of esophageal squamous cell carcinoma. If the result will be the same effect and fewer side effects and less costly in S-1 plus radiotherapy. It will supply more treatment selection for esophageal squamous cell carcinoma.

Endothelial progenitor cells are capable of contributing to neovascularization in tumours. In patients with either malignant or transudative pleural effusion, we tested the presence of pleural endothelial progenitor cells. We also measured the number of endothelial progenitor cells in post-surgery pleural drainage of either patients with early non-small-cell lung cancer or control patients with benign lung disease undergoing pulmonary resection. The prospective influence of post-surgery pleural-drainage endothelial progenitor cells on cancer recurrence/survival was investigated. Pleural endothelial progenitor cell levels were quantified by fluorescence-activated cell sorting analysis in pleural effusion of 15 patients with late-stage non-small-cell lung cancer with pleural involvement and in 15 control patients with congestive heart failure. Also, pleural-drainage endothelial progenitor cells were measured in pleural-drainage fluid 48 h after surgery in 64 patients with early-stage non-small-cell lung cancer and 20 benign lung disease patients undergoing pulmonary resection. Cancer recurrence and survival was evaluated in patients with high pleural-drainage endothelial progenitor cell levels. The number of pleural endothelial progenitor cells was higher in non-small-cell lung cancer pleural effusion than in transudative pleural effusion. Also, pleural-drainage endothelial progenitor cell levels were higher in patients with non-small-cell lung cancer than in patients with benign lung disease undergoing pulmonary resection (P < 0.05). Non-small-cell lung cancer patients with high pleural-drainage endothelial progenitor cell levels had a significantly 4.9 higher rate of cancer recurrence/death than patients with lower pleural-drainage endothelial progenitor cell levels, irrespective of confounders. Endothelial progenitor cells are present in the pleural effusion and are higher in patients with late-stage non-small-cell lung cancer with pleural involvement than in congestive heart failure patients. Endothelial progenitor cell levels are higher in the post-surgery pleural drainage of patients with non-small-cell lung cancer than in non-neoplastic pleural-drainage fluid. High pleural-drainage endothelial progenitor cell levels in patients undergoing pulmonary resection for early non-small-cell lung cancer predict an increased risk of cancer recurrence and death. © The Author 2016.

Talc pleurodesis is commonly used in the palliative treatment of malignant pleural effusions but the shortest and most effective regime has not been determined. In particular, it is not clear when the intercostal drain should be removed following the insertion of sclerosant. We conducted a single-centre, randomised, open trial of drain removal at 24 h versus 72 h following talc slurry pleurodesis. The primary outcome measure was success of pleurodesis (no recurrence of effusion on chest radiograph at 1-month follow-up) and secondary outcome measures included length of hospital stay and mortality. We found no difference between recurrence of pleural effusion in those randomised to drain removal at 24 h and those randomised to drain removal at 72 h (p>0.5). However, length of stay was significantly reduced when the chest drain was removed at 24 h (4 days versus 8 days; p<0.01). Mortality did not differ between the two groups. We conclude that this shorter pleurodesis regime is safe and effective.

Electrical impedance tomography (EIT) is increasingly used for continuous monitoring of ventilation in intensive care patients. Clinical observations in patients with pleural effusion show an increase in out-of-phase impedance changes. We hypothesised that out-of-phase impedance changes are a typical EIT finding in patients with pleural effusion and could be useful in its detection. We conducted a prospective observational study in intensive care unit patients with and without pleural effusion. In patients with pleural effusion, EIT data were recorded before, during, and after unilateral drainage of pleural effusion. In patients with no pleural effusion, EIT data were recorded without any intervention. EIT images were separated into four quadrants of equal size. We analysed the sum of out-of-phase impedance changes in the affected quadrant in patients with pleural effusion before, during, and after drainage and compared it with the sum of out-of-phase impedance changes in the dorsal quadrants of patients without pleural effusion. We included 20 patients with pleural effusion and 10 patients without pleural effusion. The median sum of out-of-phase impedance changes was 70 (interquartile range 49-119) arbitrary units (a.u.) in patients with pleural effusion before drainage, 25 (12-46) a.u. after drainage (P<0.0001) and 11 (6-17) a.u. in patients without pleural effusion (P<0.0001 vs pleural effusion before drainage). The area under the receiver operating characteristics curve was 0.96 (95% limits of agreement 0.91-1.01) between patients with pleural effusion before drainage and those without pleural effusion. In patients monitored with EIT, the presence of out-of-phase impedance changes is highly suspicious of pleural effusion and should trigger further examination.

Malignant pleural effusion is a common complication in end-stage cancer patients and can cause severe dyspnea. Therapeutic thoracentesis is often limited to 1 to 1.5 L. Pleural manometry can be used to recognize a not-expanded lung. Interval pleural pressure measurements with a high temporal resolution were performed after each removal of 200 mL of fluid to observe pleural pressure swings. Pleural elastance was defined as the difference in pleural pressure divided by the change in volume. Chest x-rays were performed to evaluate lung expansion, reexpansion pulmonary edema, and fluid residue. Thirty-four procedures in 30 patients were eligible for analysis. Four patients had incomplete lung expansion after drainage. No reexpansion pulmonary edema was observed. Pleural pressure swing after 200 mL drainage was higher when the lung did not expand. Pleural elastance after removal of 500 mL was higher in the not-expanded subgroup. We demonstrated that a high pleural pressure swing after removal of only 200 mL was related to incomplete lung expansion. We confirmed the association between pleural elastance and lung expansion.

Introduction. We investigated the expression of microRNAs and mRNAs in pleural tissues from patients with either malignant pleural mesothelioma or benign asbestos-related pleural effusion. Methods. Fresh frozen tissues from a total of 18 malignant pleural mesothelioma and 6 benign asbestos-related pleural effusion patients were studied. Expression profiling of mRNA and microRNA was performed using standard protocols. Results. We discovered significant upregulation of multiple microRNAs in malignant pleural mesothelioma compared to benign asbestos-related pleural effusion. Hsa-miR-484, hsa-miR-320, hsa-let-7a, and hsa-miR-125a-5p were able to discriminate malignant from benign disease. Dynamically regulated mRNAs were also identified. MET was the most highly overexpressed gene in malignant pleural mesothelioma compared to benign asbestos-related pleural effusion. Integrated analyses examining microRNA-mRNA interactions suggested multiple altered targets within the Notch signaling pathway. Conclusions. Specific microRNAs and mRNAs may have diagnostic utility in differentiating patients with malignant pleural mesothelioma from benign asbestos-related pleural effusion. These studies may be particularly helpful in patients who reside in a region with a high incidence of mesothelioma. PMID:25756049

The goal of this study was to isolate cancer stem-like cells marked by high expression of CD44, a putative cancer stem cell marker, from primary oral squamous cell carcinomas and identify distinctive gene expression patterns in these cells. From 1 October 2013 to 4 September 2015, 76 stage III-IV primary oral squamous cell carcinoma of the gingivobuccal sulcus were resected. In all, 13 tumours were analysed by immunohistochemistry to visualise CD44-expressing cells. Expression of CD44 within The Cancer Genome Atlas-Head and Neck Squamous Cell Carcinoma RNA-sequencing data was also assessed. Seventy resected tumours were dissociated into single cells and stained with antibodies to CD44 as well as CD45 and CD31 (together referred as Lineage/Lin). From 45 of these, CD44 + Lin - and CD44 - Lin - subpopulations were successfully isolated using fluorescence-activated cell sorting, and good-quality RNA was obtained from 14 such sorted pairs. Libraries from five pairs were sequenced and the results analysed using bioinformatics tools. Reverse transcription quantitative polymerase chain reaction was performed to experimentally validate the differential expression of selected candidate genes identified from the transcriptome sequencing in the same 5 and an additional 9 tumours. CD44 was expressed on the surface of poorly differentiated tumour cells, and within the The Cancer Genome Atlas-Head and Neck Squamous Cell Carcinoma samples, its messenger RNA levels were higher in tumours compared to normal. Transcriptomics revealed that 102 genes were upregulated and 85 genes were downregulated in CD44 + Lin - compared to CD44 - Lin - cells in at least 3 of the 5 tumours sequenced. The upregulated genes included those involved in immune regulation, while the downregulated genes were enriched for genes involved in cell adhesion. Decreased expression of PCDH18, MGP, SPARCL1 and KRTDAP was confirmed by reverse transcription quantitative polymerase chain reaction. Lower expression of the cell-cell adhesion molecule PCDH18 correlated with poorer overall survival in the The Cancer Genome Atlas-Head and Neck Squamous Cell Carcinoma data highlighting it as a potential negative prognostic factor in this cancer.

Squamous cell carcinoma (SqCC) of the breast should be differentiated between the primary skin keratinizing squamous carcinoma and squamous metaplastic cancer. In the current study, the cases of two patients who were diagnosed with SqCC originated from skin and the breast were discussed. A fine-needle aspiration biopsy confirmed the presence of atypical squamous cells. In both cases, the microscopic examination of the surgical specimen revealed a malignant neoplasm differentiated into SqCC characterized by keratinizing cancer cells with abundant eosiphilic cytoplasm with large, hyperchromatic vesicular nuclei. Immunohistochemical studies showed negative for progesterone and estrogen receptors and human epidermal growth factor receptor 2. Moreover, negative expression of cytokeratin 7 and 20 was confirmed. The diagnosis of the both tumors was established based on the detailed analysis of clinical, macroscopical and microscopical information. SqCC localized in the breast is a great diagnostic challenge in pathomorphology and more attention should be paid for analysis of such lesions in daily practice. PMID:29556390

Recurrent oropharyngeal squamous cell carcinoma causes great morbidity and mortality. This systematic review analyses survival outcomes following salvage surgery for recurrent oropharyngeal squamous cell carcinoma. A comprehensive search of various electronic databases was conducted. Studies included patients with recurrent or residual oropharyngeal squamous cell carcinoma treated with salvage surgery. Primary outcomes were survival rates following salvage surgery. Secondary outcomes included time to recurrence, staging at time of recurrence, post-operative complications, and factors associated with mortality and recurrence. Methodological appraisal and data extraction were conducted as per Joanna Briggs Institute methodology. Eighteen articles were included. The two- and five-year survival rates of the patients were 52 per cent and 30 per cent respectively. Improvements in treatment modalities for recurrent oropharyngeal squamous cell carcinoma were associated with improvements in two-year overall survival rates, with minimal change to five-year overall survival rates. Various factors were identified as being associated with long-term overall survival, thus assisting clinicians in patient counselling and selection for salvage surgery.

[Imaging of pleural diseases: evaluation of imaging methods based on chest radiography].

PubMed

Poyraz, Necdet; Kalkan, Havva; Ödev, Kemal; Ceran, Sami

2017-03-01

The most commonly employed radiologic method in diagnosis of pleural diseases is conventional chest radiograph. The commonest chest- X-Ray findings are the presence of pleural effusion and thickening. Small pleural effusions are not readily identified on posteroanterior chest radiograph. However, lateral decubitus chest radiograph and chest ultrasonography may show small pleural effusions. These are more efficient methods than posteroanterior chest radiograph in the erect position for demonstrating small amounts of free pleural effusions. Chest ultrasonograph may be able to help in distinguishing the pleural pathologies from parenchymal lesions. On chest radiograph pleural effusions or pleural thickening may obscure the visibility of the underlying disease or parenchymal abnormality. Thus, computed tomography (CT) may provide additional information of determining the extent and severity of pleural disease and may help to differentiate malign pleural lesions from the benign ones. Moreover, CT may provide the differentiation of parenchmal abnormalities from pleural pathologies. CT (coronal and sagittal reformatted images) that also show invasion of chest wall, mediastinum and diaphragm, as well as enlarged hilar or mediastinal lymph nodes. Standart non-invasive imaging techniques may be supplemented with magnetic resonans imaging (MRI).

Medical thoracoscopy (MT) is a diagnostic and therapeutic procedure that permits the study of the pleural space. The presence of pleural adhesions is the most important contraindication to performing MT. Lesions of the pleura in absence of pleural effusion are usually studied in video-assisted thoracoscopic surgery (VATS) with preoperative ultrasound evaluation. No data are available about ultrasound-guided MT in the absence of pleural effusion. From January 2007 to June 2013, 622 consecutive MTs were performed under ultrasound guidance without inducing a pneumothorax. A retrospective cohort of 29 patients affected by pleural diseases without fluid was reviewed. The fifth or sixth intercostal spaces along the midaxillary line with a good echographic "sliding sign" and normal appearance of the pleural line were chosen as the entry site. The pleural cavity was explored, and biopsies were performed. The mean age of the patient cohort was 62.8 years; there were 20 male patients and nine female patients. Pleural adherences were avoided, and adequate number of pleural biopsies were performed. No parenchymal lung injuries, bleeding, or hematoma occurred. Seventeen patients had a completely free pleural cavity, four patients had a single pleural adhesion, and eight had multiple pleural adhesions; in all cases, however, endoscopic exploration was possible and biopsy specimens were adequate. The most frequent histopathologic diagnosis was malignant pleural mesothelioma. We have shown that thoracic ultrasound accurately identifies intrathoracic adhesions and, in experienced hands, can guide MT access, replacing the VATS approach, even in the complete absence of pleural effusion.

Malignant pleural effusion can be recurrent despite active anti-cancer treatment. Significant malignant pleural effusion leads to debilitating dyspnoea and worsening quality of life in patients with advanced cancer. An indwelling pleural catheter offers a novel means to manage recurrent malignant pleural effusion and may remove the need for repeated thoracocentesis. Spontaneous pleurodesis is another unique advantage of indwelling pleural catheter placement but the factors associated with its occurrence are not clearly established. The aims of this study were to explore the safety of an indwelling pleural catheter in the management of symptomatic recurrent malignant pleural effusion, and to identify the factors associated with spontaneous pleurodesis. This case series with internal comparisons was conducted in the Division of Respiratory Medicine, Department of Medicine, Queen Mary Hospital, Hong Kong. All patients who underwent insertion of an indwelling pleural catheter from the initiation of such service from January 2010 to December 2014 were included for data analysis. Patients were monitored until December 2014, with the last catheter inserted in July 2014. Between 2010 and 2014, a total of 23 indwelling pleural catheters were inserted in 22 consecutive patients with malignant pleural effusion, including 15 (65.2%) cases with malignant pleural effusion as a result of metastatic lung cancer. Ten (43.5%) cases achieved minimal output according to defined criteria, in five of whom the pleural catheter was removed without subsequent re-accumulation of effusion (ie spontaneous pleurodesis). Factors associated with minimal output were the absence of trapped lung (P=0.036), shorter time from first appearance of malignant pleural effusion to catheter insertion (P=0.017), and longer time from catheter insertion till patient's death or end of study (P=0.007). An indwelling pleural catheter provides a safe means to manage symptomatic malignant pleural effusion. Potential clinical factors associated with minimal output were identified along with the occurrence of spontaneous pleurodesis, which is a unique advantage offered by indwelling pleural catheter.

We studied the diagnostic potential of serum lactate dehydrogenase (LDH) in malignant pleural effusion. Retrospective analysis of patients hospitalized with exudative pleural effusion in 2013. Serum LDH and serum LDH: pleural fluid ADA ratio was significantly higher in cancer patients presenting with exudative pleural effusion. In multivariate logistic regression analysis, pleural fluid ADA was negatively correlated 0.62 (0.45-0.85, p = 0.003) with malignancy, whereas serum LDH 1.02 (1.0-1.03, p = 0.004) and serum LDH: pleural fluid ADA ratio 0.94 (0.99-1.0, p = 0.04) was correlated positively with malignant pleural effusion. For serum LDH: pleural fluid ADA ratio, a cut-off level of >20 showed sensitivity, specificity of 0.98 (95 % CI 0.92-0.99) and 0.94 (95 % CI 0.83-0.98), respectively. The positive likelihood ratio was 32.6 (95 % CI 10.7-99.6), while the negative likelihood ratio at this cut-off was 0.03 (95 % CI 0.01-0.15). Higher serum LDH and serum LDH: pleural fluid ADA ratio in patients presenting with exudative pleural effusion can distinguish between malignant and non-malignant effusion on the first day of hospitalization. The cut-off level for serum LDH: pleural fluid ADA ratio of >20 is highly predictive of malignancy in patients with exudative pleural effusion (whether lymphocytic or neutrophilic) with high sensitivity and specificity.

Spindle cell carcinoma (SpCC), which predominantly arises in the oral, pharyngeal and laryngeal mucosal tissues, is composed of a mixture of squamous and sarcomatoid components. The present study describes the case of a 62-year-old woman with SpCC recurrence 4 years after an initial surgery to remove a well-differentiated primary squamous cell carcinoma (SCC) of the tongue. The recurrent tumor was spherical and located deep within the tongue tissue, which differs from the typical manifestation of ulcerated masses of the mucosa. The majority of cases of recurrence involving SpCC are associated with radiotherapeutic treatment of the primary malignancy; however, the patient in the present study had not received postoperative radiotherapy for SCC. Furthermore, the recurrent tumor in the present case exhibited marked anaplasia and sarcomatoid features, and the absence of SCC elements upon biopsy rendered histological diagnosis difficult. In summary, the present findings suggest that immunohistochemical examination and identification of SCC components are essential for ensuring the accuracy of the histological diagnosis of recurrent SpCC following a primary epithelial malignancy.

A 55-year-old Indian man presented with productive cough and a large left pleural effusion. Pleural fluid culture grew Mycobacterium tuberculosis, and he was started on antituberculosis therapy. One week later, the patient presented to hospital with drowsiness, dehydration and hypotension. He was transferred to critical care and only improved after starting hydrocortisone and stopping rifampicin. His short synACTHen test subsequently confirmed primary adrenal insufficiency, and a CT of the abdomen showed bilateral adrenal enlargement. Rifampicin is known to accelerate cortisol metabolism. We report the rare case of a rifampicin-induced adrenal crisis as a first presentation of Addison's disease in a patient with tuberculous infiltration of the adrenal glands. 2016 BMJ Publishing Group Ltd.

Primary intraosseous squamous cell carcinoma in odontogenic keratocyst: A rare entity

2015-01-01

Squamous cell carcinoma (SCC) arising from the wall of an odontogenic cyst (also known as primary intraosseous carcinoma) is a rare tumor which occurs only in jaw bones. This tumor was first described by Loos in 1913 as a central epidermoid carcinoma of the jaw. Primary intraosseous carcinomas (PIOC) may theoretically arise from the lining of an odontogenic cyst or de novo from presumed odontogenic cell rests. According to the new histological classification of tumors of the World Health Organization, odontogenic keratocyst is nowadays considered a specific odontogenic tumor and the PIOC derived from it is considered as a specific entity which is different from other PIOCs derived from the odontogenic cysts. The following report describes a case of such extremely rare entity that is primary intraosseous SCC of the mandible derived from an OKC in a 60-year-old male patient with brief review of literature.

Synchronous primary carcinomas of gallbladder are extremely rare. In this paper, we report a case of double primary carcinomas in gallbladder CASE REPORT: A 65 year old male was admitted to the hospital for surgical removal of gallbladder, which was diagnosed as cholecystitis in ultrasonography. Macroscopic examination disclosed a single whitish mass in gallbladder neck and another distinct mass in the fundus as wall thickening. Pathologic findings revealed squamous cell carcinoma of the neck and adenocarcinoma in the fundus. This study represents an example of misdiagnosis. Being cautious is mandatory in order to manage the patient properly. Synchronous primary carcinomas of gallbladder are rare. However this diagnosis should be taken into account in patients with cholecystitis features in order to seeking for the best surgical approach. Copyright © 2018 The Authors.

Pleural fluid adenosine deaminase level can be applied to rapidly detect tuberculous pleural effusion. We aimed to establish a local diagnostic cut-off value for pleural fluid adenosine deaminase to identify patients with tuberculous pleural effusion, and optimise its utility. We retrospectively reviewed the medical records of consecutive adults with pleural fluid adenosine deaminase level measured by the Diazyme commercial kit (Diazyme Laboratories, San Diego [CA], United States) during 1 January to 31 December 2011 in a cluster of public hospitals in Hong Kong. We considered its level alongside early (within 2 weeks) findings in pleural fluid and pleural biopsy, with and without applying Light's criteria in multiple scenarios. For each scenario, we used the receiver operating characteristic curve to identify a diagnostic cut-off value for pleural fluid adenosine deaminase, and estimated its positive and negative predictive values. A total of 860 medical records were reviewed. Pleural effusion was caused by congestive heart failure, chronic renal failure, or hypoalbuminaemia caused by liver or kidney diseases in 246 (28.6%) patients, malignancy in 198 (23.0%), non-tuberculous infection in 168 (19.5%), tuberculous pleural effusion in 157 (18.3%), and miscellaneous causes in 91 (10.6%). All those with tuberculous pleural effusion had a pleural fluid adenosine deaminase level of ≤100 U/L. When analysis was restricted to 689 patients with pleural fluid adenosine deaminase level of ≤100 U/L and early negative findings for malignancy and non-tuberculous infection in pleural fluid, the positive predictive value was significantly increased and the negative predictive value non-significantly reduced. Using this approach, neither additionally restricting analysis to exudates by Light's criteria nor adding closed pleural biopsy would further enhance predictive values. As such, the diagnostic cut-off value for pleural fluid adenosine deaminase is 26.5 U/L, with a sensitivity of 87.3%, specificity of 93.2%, positive predictive value of 79.2%, negative predictive value of 96.1%, and accuracy of 91.9%. Sex, age, and co-morbidity did not significantly affect prediction of tuberculous pleural effusion using the cut-off value. We have established a diagnostic cut-off level for pleural fluid adenosine deaminase in the diagnosis of tuberculous pleural effusion by restricting analysis to a level of ≤100 U/L, and considering early pleural fluid findings for malignancy and non-tuberculous infection, but not Light's criteria.

Image-guided pleural biopsies, both using ultrasound (US) or computed tomography (CT), are important in the diagnosis of pleural disease. However, no consensus exists regarding which biopsy needles are appropriate for specific procedures. In this randomized, prospective study, we aimed to compare CT scan-guided pleural biopsy using an Abrams' needle (CT-ANPB) with US-assisted pleural biopsy using a cutting needle (US-CNPB) with respect to both diagnostic yield and safety. Between February 2009 and April 2013, 150 patients with exudative pleural effusion who could not be diagnosed by cytological analysis were included in the study. The patients were randomized into either the US-CNPB group or the CT-ANPB group. The two groups were compared in terms of diagnostic sensitivity and complications. Of the 150 patients enrolled in this study, 45 were diagnosed with malignant mesothelioma, 46 were diagnosed with metastatic pleural disease, 18 were diagnosed with pleural tuberculosis, 34 were diagnosed with benign pleural disease, and 7 were lost to follow-up. In the US-CNPB group, the diagnostic sensitivity was 66.7%, compared with 82.4% in the CT-ANPB group; the difference between the two groups was statistically significant (p = 0.029). The sensitivity of CT-ANPB increased to 93.7% for patients with a pleural thickness ≥1 cm. The complication rates were low and acceptable. The first diagnostic intervention that should be preferred in patients with pleural effusion and associated pleural thickening on a CT scan is CT-ANPB. US-CNPB should be used primarily in cases for which only pleural thickening but no pleural effusion is noted. © 2016 S. Karger AG, Basel.

While the increased risk of lung cancer and mesothelioma is well established, the relationship between exposure to asbestos dust and sinonasal cancer is less clear. To study the risk of sinonasal cancer in relation to asbestos dust exposure. A retrospective cohort study of construction workers, linked to the Swedish Cancer Registry. Participants were classified into four exposure groups; heavy, medium, low or very low exposure to asbestos, according to the incidence of pleural mesothelioma in their occupational group. Standardized incidence ratios (SIRs) and relative risks (RRs) were analysed, adjusted for age and smoking habits. The risks of adenocarcinoma and squamous cell carcinoma were investigated separately. Among the 280222 subjects, there was no increased risk of sinonasal cancer compared to the general population [SIR 0.85, 95% confidence interval (CI) 0.68-1.03], or any dose-response relationship with exposure to asbestos. The highest RR was found in the low exposure group (RR 1.25, 95% CI 0.69-2.28) and the lowest RR was found in the group with the highest exposure to asbestos (RR 0.71, 95% CI 0.33-1.53). No significantly increased risk or dose-response association could be found for adenocarcinoma or squamous cell carcinoma when analysed separately. This study did not find an increased risk of developing sinonasal cancer after asbestos exposure. © The Author 2016.

The goal of this work was to develop an LC-MRM assay for the quantitative analysis of a set of established and diagnostically important cytokeratin (CK) markers used in cancer diagnosis, prognosis, and therapy monitoring. Second, the potential of this assay in lung cancer diagnosis through pleural effusion (PE) analysis was examined. A multiplexed MRM assay was developed for 17 CKs and their select caspase-cleaved fragments. Isotope-labeled standard peptides were used for high assay specificity and absolute peptide quantitation; with robust standard-flow LC coupled to a latest-generation triple-quadrupole instrument for high sensitivity. The potential clinical applicability was demonstrated by the analysis of 118 PE samples. The MRM assay was evaluated for endogenous detection, linearity, precision, upper and lower limits of quantification, selectivity, reproducibility and peptide stability, and is generally applicable to any epithelial cancer study. A set of 118 patients with known pathologies allowed us to define the range of CK levels in clinical PE samples. Specific CKs were able to differentiate cancer-related PEs from those caused by benign ailments. In addition, they allowed to differentiate between PEs from subjects with small cell lung cancer versus non-small cell lung carcinoma, and to further differentiate the latter into its two subtypes, adenocarcinoma and squamous cell carcinoma. An MRM-based CK assay for carcinoma studies can differentiate between the three lung cancer histological types using less-invasive PE sampling providing potential therapy-guiding information on patients that are inoperable. © 2018 WILEY-VCH Verlag GmbH & Co.

Differentiating tuberculous pleural effusion from other lymphocytic pleural effusions is often challenging. This retrospective study aimed to assess the efficacy and safety of medical thoracoscopy in patients with suspected tuberculous pleural effusion. Between July 2005 and June 2014, patients with pleural effusions of unknown etiologies underwent medical thoracoscopy in our institute after less invasive means of diagnosis had failed. Demographic, radiographic, procedural, and histological data of patients with tuberculous pleural effusion were analyzed. During this 9-year study, 333 of 833 patients with pleural effusion were confirmed to have tuberculous pleurisy. Under thoracoscopy, we observed pleural nodules in 69.4%, pleural adhesion in 66.7%, hyperemia in 60.7%, plaque-like lesions in 6.0%, ulceration in 1.5% of patients with tuberculous pleurisy. Pleural biopsy revealed the presence of Mycobacterium tuberculosis in the pleural tissue or/and demonstration of caseating granulomas in 330 (99.1%) patients. No serious adverse events were recorded, and the most common minor complication was transient chest pain (43.2%) from the indwelling chest tube. Our data showed that medical thoracoscopy is a simple procedure with high diagnostic yield and excellent safety for the diagnosis of tuberculous pleural effusion. Copyright © 2015 Elsevier Ltd.

We aimed to assess the role of medical thoracoscopy in patients with undiagnosed pleural effusion. Patiens presenting with pleural effusion underwent three pleural aspirations. Patients in whom pleural fluid analysis was inconclusive underwent closed pleural biopsy for diagnostic confirmation. Patients in whom closed pleural biopsy was incolcusive underwent medical thoracoscopy using a rigid thoracoscope with a viewing angle of zero degrees was done under local anaesthesia and sedation with the patient lying in lateral decubitus position with the affected side up. Biopsy specimens from parietal pleura were obtained under direct vision and were sent for histopathological examination. Of the 128 patients with pleural effusion who were studied, pleural fluid examination established the diagnosis in 81 (malignancy 33, tuberculosis 33, pyogenic 14 and fungal 1); 47 patients underwent closed pleural biopsy and a diagnosis was made in 28 patients (malignancy 24, tuberculosis 4). The remaining 19 patients underwent medical thoracoscopy and pleural biopsy and the aetiological diagnosis could be confirmed in 13 of the 19 patients (69%) (adenocarcinoma 10, poorly differentiated carcinoma 2 and mesothelioma 1). Medical thoracoscopy is a useful tool for the diagnosis of pleural diseases. The procedure is safe with minimal complications.

State-of-the-art: Radiological investigation of pleural disease.

Pleural disease is common. Radiological investigation of pleural effusion, thickening, masses, and pneumothorax is key in diagnosing and determining management. Conventional chest radiograph (CXR) remains as the initial investigation of choice for patients with suspected pleural disease. When abnormalities are detected, thoracic ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) can each play important roles in further investigation, but appropriate modality selection is critical. US adds significant value in the identification of pleural fluid and pleural nodularity, guiding pleural procedures and, increasingly, as "point of care" assessment for pneumothorax, but is highly operator dependent. CT scan is the modality of choice for further assessment of pleural disease: Characterising pleural thickening, some pleural effusions and demonstration of homogeneity of pleural masses and areas of fatty attenuation or calcification. MRI has specific utility for soft tissue abnormalities and may have a role for younger patients requiring follow-up serial imaging. MRI and PET/CT may provide additional information in malignant pleural disease regarding prognosis and response to therapy. This article summarises existing techniques, highlighting the benefits and applications of these different imaging modalities and provides an up to date review of the evidence.

2015-02-01

To summarize the clinical features and the diagnosis-treatment points of sarcoidosis related pleural effusion. Six typical sarcoidosis related pleural effusion cases with pathological evidence were reviewed, and the clinical data of these cases were retrospectively analyzed and the related literatures were reviewed. The literature review was carried out respectively with "sarcoidosis", "pleural disease" and "pleural effusion" as the keywords in CNKI and PubMed database by January 2014. Six cases, including 1 male and 5 females, with sarcoidosis related pleural effusions were reported. 3 cases had bilateral effusions, 2 cases had left effusion and 1 case had right effusion. The pleural effusion routine test had a low specificity, which demonstrated that the fluid was exudate and consisted with large number of lymphocytes. 3 of these cases were diagnosed by medical thoracoscopy. Medical thoracoscopy revealed that pleural involvement was variable with multiple nodulespresent in some cases and subtle change in others. A total of 28 literatures and 92 cases with pleural involvement in sarcoidosis were retrieved from CNKI and PubMed database (time range: 2004.1-2014.1), including 59 cases of pleural effusion, 29 cases of pleural thickening, 3 cases of pneumothorax and 1 case of nodules in pleura. Pleural involvement in sarcoidosis was often misdiagnosed or mistreated as tuberculous pleurisy because the routine tests regarding pleural effusion usually had a low specificity. Medical thoracoscopy could provide clinicians with important clues to assist differentiation of the cause for non-conclusive pleural effusion in this situation.

In this systematic review, we evaluated studies involving adjuvant and primary topical treatment for ocular surface squamous neoplasia (OSSN). The findings were: (i) adjuvant 5-fluorouracil (5-FU) reduces the risk of relapse after surgical excision with mild side effects [level Ib, grade of recommendation (GR) A]. (ii) Primary topical mitomycin (MMC) produces a high rate of complete response, low recurrence rate, and mild side effects (level Ib, GR A). (iii) Primary chemotherapy versus adjuvant chemotherapy produce similar rates of recurrence, with no significant difference (level IIb, GR B). (iv) Adjuvant 5-FU versus MMC showed no significant differences, with mild side effects in both groups and a better toxicity profile for MMC (level III, GR C). (v) Primary topical 5-FU versus MMC versus interferon (IFN) showed similar rates of tumor recurrence, mild side effects for all drugs, and more severe side effects in the 5-FU arm, followed successively by MMC and IFN (level III, GR C).

The mechanism(s) by which chronic inhalation of indium phosphide (InP) particles causes pleural fibrosis is not known. Few studies of InP pleural toxicity have been conducted because of the challenges in conducting particulate inhalation exposures, and because the pleural lesions developed slowly over the 2-year inhalation study. The authors investigated whether InP (1 mg/kg) administered by a single oropharyngeal aspiration would cause pleural fibrosis in male B6C3F1 mice. By 28 days after treatment, protein and lactate dehydrogenase (LDH) were significantly increased in bronchoalveolar lavage fluid (BALF), but were unchanged in pleural lavage fluid (PLF). A pronounced pleural effusion characterized by significant increases in cytokines and a 3.7-fold increase in cell number was detected 28 days after InP treatment. Aspiration of soluble InCl3 caused a similar delayed pleural effusion; however, other soluble metals, insoluble particles, and fibers did not. The effusion caused by InP was accompanied by areas of pleural thickening and inflammation at day 28, and by pleural fibrosis at day 98. Aspiration of InP produced pleural fibrosis that was histologically similar to lesions caused by chronic inhalation exposure, and in a shorter time period. This oropharyngeal aspiration model was used to provide an initial characterization of the progression of pleural lesions caused by InP. PMID:19995279

Using the indirect ELISA technique, the IgM, IgG, and IgA antibody response to the primary test immunogen Helix pomatia haemocyanin (HPH) was studied in 30 patients with various clinical stages of primary squamous-cell bronchial carcinoma and compared with values obtained in 15 controls matched for sex, age, smoking habit, and presence of chronic bronchitis. Patients with disseminated disease (stage III) showed a significant decrease in IgG and IgA antibody response (P less than 0.001), but IgM antibodies were relatively high and not different from the controls. Although normal IgG and IgA antibody titres were found at the peak response two weeks after immunisation in patients with localised disease (stage I), these antibody titres showed a significantly more rapid decline after serial investigations at eight and 14 weeks after immunisation compared with the controls (P less than 0.001) despite total removal of the tumour burden at c four weeks after immunisation. In-vitro HPH-induced lymphocyte transformation was considerably decreased in state I patients (P less than 0.01) as well as in stage III patients (P less than 0.001). The results suggest that patients with squamous-cell bronchial carcinoma develop impaired T-cell function, which gives rise to a defective antibody response and in-vitro lymphocyte reactivity to the T-cell dependent primary immunogen HPH.

A 48-year-old woman with a 3-month history of back pain was admitted for further examination of multiple left pleural nodules. She had undergone bilateral breast augmentation with silicone implants 10 years previously. Nine years after the operation, both ruptured implants were removed, and autologous fat was injected. Computed tomography revealed multiple pleural nodules suggestive of malignant pleural mesothelioma. Thoracoscopic exploration revealed multiple pleural nodules with massive pleural adhesions. The nodules were filled with viscous liquid and were histologically determined to be siliconomas. Disseminated pleural siliconoma should be recognized as a late adverse event of silicone breast implantation. Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Diffuse malignant pleural mesothelioma (DMPM) is the most common primary malignant pleural neoplasm still posing major diagnostic, prognostic and therapeutic challenges. Plakophilins are structural proteins considered to be important for cell stability and adhesion in both tumor and normal tissues. Plakophilin 3 is a protein present in desmosomes of stratified and simple epithelia of normal tissues with presence in malignant cells of various tumors where it participates in the process of tumorigenesis. The aim of this study was to investigate the expression of plakophilin 3 protein in DMPM, but also to study its prognostic significance and relation to histologically accessible parameters of aggressive growth. Archival samples of tissue with established diagnosis of DMPM and samples of normal pleural tissue were used. Tumor samples were classified into three histological types of DMPM (epithelioid, sarcomatoid and biphasic). Additional subclassification of epithelioid mesotheliomas into nine patterns based on the prevalent histological component of the tumor was then performed. After immunohistochemical staining, cytoplasmic and membrane immunopositivity of tumor cells was assesed by scoring the intensity of the staining from 0 (no staining) to 4 (very strong staining). Prognostic value and expression of plakophilin 3 with consideration to histologically estimated aggression in tumor growth were then statistically analyzed using non- parametric tests. The results demonstrated higher level of plakophilin 3 expression in tumor samples with histologically more aggressive tumor growth, but no significant prognostic value. According to our study, plakophilin 3 appears to be involved in tumor invasion in malignant mesothelioma.

Effects of ventilation on hyaluronan and protein concentration in pleural liquid of anesthetized and conscious rabbits.

PubMed

Wang, P M; Lai-Fook, S J

1998-01-01

The hypothesis of this study is that pleural lubrication is enhanced by hyaluronan acting as a boundary lubricant in pleural liquid and by pleural filtration as reflected in changes in protein concentration with ventilation. Anesthetized rabbits were injected intravenously with Evans blue dye and ventilated with 100% O2 at either of two levels of ventilation for 6 h. Postmortem values of hyaluronan, total protein, and Evans blue-dyed albumin (EBA) concentrations in pleural liquid were greater at the higher ventilation, consistent with increases in boundary lubrication, pleural membrane permeability, and pleural filtration. To determine whether these effects were caused by hyperoxia or anesthesia, conscious rabbits were ventilated with either 3% CO2 or room air in a box for 6, 12, or 24 h. Similar to the anesthetized rabbits, pleural liquid hyaluronan concentration after 24 h was higher in the conscious rabbits with the hypercapnic-induced greater ventilation. By contrast, the time course of total protein and EBA in pleural liquid was similar in both groups of conscious rabbits, indicating no effect of ventilation on pleural permeability. The increase in pleural liquid hyaluronan concentration might be the result of mesothelial cell stimulation by a ventilation-induced increase in pleural liquid shear stress.

To elucidate differences in the level and localization of pleural irregularities in early malignant pleural mesothelioma (eMPM) and benign asbestos pleural effusion (BAPE) using CT. Retrospective assessment of CT findings of consecutive patients with BAPE at a single centre and patients with eMPM reported in Japanese vital statistics. Thirty-six patients with confirmed diagnoses of BAPE and sixty-six patients with confirmed diagnoses of eMPM (mesothelioma stages T1 or T2) were included. Informed consent, CT scans, and clinical and pathologic details were obtained for all patients and were reviewed by one radiologist, two pathologists, and two pulmonologists. Asbestosis, pleural plaque, rounded atelectasis, and diffuse pleural thickening were assessed in all patients. Prevalence of asbestosis, pleural plaque, rounded atelectasis, and diffuse pleural thickening was significantly higher in the BAPE group. Low-level irregularity was more common in the BAPE group (p<0.001), whereas high-level irregularity, mediastinal localization, and interlobar fissure were more prevalent in the eMPM group (p<0.001). Interlobar pleural irregularity was not observed in any patients in the BAPE group, although 55% of patients in the eMPM group showed interlobar pleural irregularity. Mediastinal pleural involvement was observed in 74% of patients in the eMPM group and had a positive predictive value of 89%. This study demonstrates that the level and localization of plural irregularities significantly differed between patients with BAPE and eMPM. Large-scale prospective studies are needed to fully establish the diagnostic utility of such differences. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The usefulness of clinical, radiological and pleural fluid analytical parameters for diagnosing malignant and paramalignant pleural effusion is not clearly stated. Hence this study aimed to identify possible predictor variables of diagnosing malignancy in pleural effusion of unknown aetiology. Clinical, radiological and pleural fluid analytical parameters were obtained from consecutive patients who had suffered pleural effusion of unknown aetiology. They were classified into three groups according to their final diagnosis: malignant, paramalignant and benign pleural effusion. The CHAID (Chi-square automatic interaction detector) methodology was used to estimate the implication of the clinical, radiological and analytical variables in daily practice through decision trees. Of 71 patients, malignant (n = 31), paramalignant (n = 15) and benign (n = 25), smoking habit, dyspnoea, weight loss, radiological characteristics (mass, node, adenopathies and pleural thickening) and pleural fluid analytical parameters (pH and glucose) distinguished malignant and paramalignant pleural effusions (all with a p < 0.05). Decision tree 1 classified 77.8% of malignant and paramalignant pleural effusions in step 2. Decision tree 2 classified 83.3% of malignant pleural effusions in step 2, 73.3% of paramalignant pleural effusions and 91.7% of benign ones. The data herein suggest that the identified predictor values applied to tree diagrams, which required no extraordinary measures, have a higher rate of correct identification of malignant, paramalignant and benign effusions when compared to techniques available today and proved most useful for usual clinical practice. Future studies are still needed to further improve the classification of patients.

Metastases to the breast from extramammary malignancies are infrequent, the most common primary sites are malignant melanoma, leukemia, lymphoma, and cancer of the lung, stomach, prostate and ovary. The cervical origin is exceptional. Splenic metastasis from squamous cell carcinoma of the cervix is also rare. To the best of our knowledge, only three cases of isolated splenic metastasis have been reported in the literature. We describe the case of a 55-year-old North African woman who presented with a nodule in her left breast eight months after treatment for stage IIB squamous cell uterine cervical carcinoma. The excisional biopsy with histological study demonstrated a poorly differentiated squamous cell carcinoma. A computed tomography scan revealed a splenic secondary location. We report here a case of two unusual metastatic sites of uterine cervical carcinoma, the breast and spleen. It is the first case of this association without widespread disease.

Anatomy and pathophysiology of the pleura and pleural space.

Pleural effusions are most often secondary to an underlying condition and may be the first sign of the underlying pathologic condition. The balance between the hydrostatic and oncotic forces dictates pleural fluid homeostasis. The parietal pleura has a more significant role in pleural fluid homeostasis. Its vessels are closer to the pleural space compared with its visceral counterpart; it contains lymphatic stomata, absent on visceral pleura, which are responsible for a bulk clearance of fluid. The diagnosis and successful treatment of pleural effusions requires a mixture of imaging techniques and pleural fluid analysis. Copyright © 2013. Published by Elsevier Inc.

Pleural effusion management is a common clinical situation associated with numerous pulmonary, pleural or extra-pulmonary diseases. A systematic approach is needed to enable a rapid diagnosis and an appropriate treatment. Pleural fluid analysis is the first step to perform which allows a presumptive diagnosis in most cases. Otherwise, further analysis of the pleural fluid or thoracic imaging or pleural biopsy may be necessary. This review aims at highlighting the important elements of the work-up required by a pleural effusion. Copyright © 2014 Société nationale française de médecine interne (SNFMI).

The past, current and future of diagnosis and management of pleural disease

PubMed Central

2015-01-01

Pleural disease is frequently encountered by the chest physician. Pleural effusions arise as the sequelae of underlying disease processes including pressure/volume imbalances, infection and malignancy. In addition to pleural effusions, persistent air leaks after surgery and bronchopleural fistulae remain a challenge. Our understanding of pleural disease including its diagnosis and management, have made tremendous strides. The introduction of the molecular detection of organism specific infection, risk stratification and improvements in the non-surgical treatment of patients with pleural infection are all within reach and may be the standard of care in the very near future. Malignant pleural effusion management continues to evolve with the introduction of tunneled pleural catheters and procedures combining that and chemical pleurodesis. These advances in the diagnostic and therapeutic evaluation of pleural disease as well as what seems to be an increasing multidisciplinary interest in the space foretell a bright future.

Pleural Effusion Developing in Two Patients on Continuous Ambulatory Peritoneal Dialysis.

PubMed

Asim, Muhammad

2016-11-01

Two patients with end-stage-renal-disease on continuous ambulatory peritoneal dialysis (CAPD) presented with pleural effusions. The aspirated fluid was categorised as transudate, based on alkaline pH, low protein and lactic dehydrogenase level. A striking feature of the pleural fluid was, its very high glucose content that resulted from translocation of dextrose containing peritoneal dialysate into the pleural space via a pleuroperitoneal connection. One patient was transferred to hemodialysis, which led to complete resolution of pleural effusion. The other patient was switched to automated peritoneal dialysis, using small dwell volumes with consequent reduction in size of the pleural effusion. Pleuroperitoneal leak should always be considered in the differential diagnosis of pleural effusion in CAPD patients. Although isotopic peritoneography can demonstrate reflux of the tracer in the pleural space, measurement of pleural fluid glucose is a simpler and reliable way of diagnosing pleuroperitoneal communication.

Pleural fibrosis is defined as an excessive deposition of extracellular matrix (ECM) components that results in destruction of the normal pleural tissue architecture. It can result from diverse inflammatory conditions, especially tuberculous pleurisy. Pleural mesothelial cells (PMCs) play a pivotal role in pleural fibrosis. Calpain is a family of calcium-dependent endopeptidases, which plays an important role in ECM remodeling. However, the role of calpain in pleural fibrosis remains unknown. In the present study, we found that tuberculous pleural effusion (TPE) induced calpain activation in PMCs and that inhibition of calpain prevented TPE-induced collagen-I synthesis and cell proliferation of PMCs. Moreover, our data revealed that the levels of angiotensin (ANG)-converting enzyme (ACE) were significantly higher in pleural fluid of patients with TPE than those with malignant pleural effusion, and ACE-ANG II in TPE resulted in activation of calpain and subsequent triggering of the phosphatidylinositol 3-kinase (PI3K)/Akt/NF-κB signaling pathway in PMCs. Finally, calpain activation in PMCs and collagen depositions were confirmed in pleural biopsy specimens from patients with tuberculous pleurisy. Together, these studies demonstrated that calpain is activated by renin-angiotensin system in pleural fibrosis and mediates TPE-induced collagen-I synthesis and proliferation of PMCs via the PI3K/Akt/NF-κB signaling pathway. Calpain in PMCs might be a novel target for intervention in tuberculous pleural fibrosis. PMID:27261452

Effect of mechanical ventilation on regional variation of pleural liquid thickness in rabbits.

PubMed

Wang, P M; Lai-Fook, S J

1997-01-01

We studied the effect of ventilation on the regional distribution of pleural liquid thickness in anesthetized rabbits. Three transparent pleural windows were made between the second and eight intercostal space along the midaxillary line of the right chest. Fluorescein isothiocyanate-labeled dextran (1 ml) was injected into the pleural space through a rib capsule and allowed to mix with the pleural liquid. The light emitted from the pleural space beneath the windows was measured by fluorescence videomicroscopy at a constant tidal volume (20 ml) and two ventilation frequencies (20 and 40 breaths/min). Pleural liquid thickness was determined from the light measurements after in vitro calibration of pleural liquid collected postmortem. At 20 breaths/min, pleural liquid thickness increased with a cranial-caudal distance from 5 microns at the second to third intercostal space to 30 microns at the sixth through eighth intercostal space. At 40 breaths/min, pleural space thickness was unchanged at the second to third intercostal space but increased to 46 microns at the sixth through eighth intercostal space. To determine this effect on pleural liquid shear stress, we measured relative lung velocity from videomicroscopic images of the lung surface through the windows. Lung velocity amplitude increased with cranial-caudal distance and with ventilation frequency. Calculated shear stress amplitude was constant with cranial-caudal distance but increased with ventilation frequency. Thus, pleural liquid thickness is matched to the relative lung motion so as to maintain a spatially uniform shear stress amplitude in pleural liquid during mechanical ventilation.

Pleural effusion recognizes heterogeneous etiology and pathogenesis and requires invasive diagnostic procedures. Usually, after pleural fluid analysis, 30-50% of patients with malignant pleural effusion exhibit negative pleural cytology, and the sensitivity of image-guided pleural needle-aspiration biopsy ranges between 60% and 70%. With the aim of differentiating between benign (BPE) and malignant (MPE) pleural effusions, several tumor markers have been assayed in the pleural fluid and the majority of studies focus on pleural carcinoembryonic antigen (p-CEA). The aims of this study were to evaluate (i) the diagnostic accuracy of p-CEA of patients with pleural effusions undergoing video-assisted thoracoscopic surgery (VATS) for diagnostic purpose, (ii) the relationship between p-CEA and serum CEA (s-CEA), and (iii) the usefulness of the p-CEA/s-CEA ratio in the diagnosis of malignant pleural effusions (MPE). We prospectively enrolled in the study 134 consecutive patients with pleural effusions, scheduled for having VATS and biopsy. The final diagnosis, based on histopathology of the VATS-guided specimens, was available for all patients. p-CEA and s-CEA was assayed with a chemiluminescence immunoassay method (CLIA), applied on the Maglumi 2000 Plus automated platform (SNIBE, Shenzen, China). The sensitivity and accuracy of p-CEA was significantly higher than that of pleural cytology at the same specificity comparing BPE with MPE and BPE with non-small lung cancer. The sensitivity of p-CEA and PC together reached 100% (BPE vs. NSCLC) and 91.5% (BPE vs. MPE excluding mesothelioma), respectively. The p-CEA measurement in patients with pleural effusion of uncertain etiology is a safe and cost-effective procedure, everywhere easily available, which may help clinicians in selecting patients for further evaluations. An elevated p-CEA level in a patient with pleural effusion and negative pleural cytology suggests the need of more invasive procedure (e.g. VATS-guided biopsies), whilst low p-CEA may support a follow-up.

The purpose of this study was to investigate the relationship between pleural temperature and pneumothorax or pleural effusion after radiofrequency (RF) ablation of lung tumors. The pleural temperature was measured immediately outside the lung surface nearest to the tumor with a fiber-type thermocouple during 25 ablation procedures for 34 tumors in 22 patients. The procedures were divided into two groups depending on the highest pleural temperature: P-group I and P-group II, with highest pleural temperatures of <40 degrees C and >/=40 degrees C, respectively. The incidence of pneumothorax or pleural effusion was compared between the groups. Multiple variables were compared between the groups to determine the factors that affect the pleural temperature. The overall incidence of pneumothorax and pleural effusion was 56% (14/25) and 20% (5/25), respectively. Temperature data in five ablation procedures were excluded from the analyses because these were affected by the pneumothorax. P-group I and P-group II comprised 10 procedures and 10 procedures, respectively. The incidence of pleural effusion was significantly higher in P-group II (4/10) than in P-group I (0/10) (p = 0.043). However, the incidence of pneumothorax did not differ significantly (p = 0.50) between P-group I (4/10) and P-group II (5/10). Factors significantly affecting the pleural temperature were distance between the electrode and the pleura (p < 0.001) and length of the lung parenchyma between the electrode and the pleura (p < 0.001). We conclude that higher pleural temperature appeared to be associated with the occurrence of pleural effusion and not with that of pneumothorax.

Pleural effusion is an abnormal collection of fluid within the pleural cavity. Excessive accumulation of pleural fluid is an important bio-marker for various illnesses, including congestive heart failure, pneumonia, metastatic cancer, and pulmonary embolism. Quantification of pleural effusion can be indicative of the progression of disease as well as the effectiveness of any treatment being administered. Quantification, however, is challenging due to unpredictable amounts and density of fluid, complex topology of the pleural cavity, and the similarity in texture and intensity of pleural fluid to the surrounding tissues in computed tomography (CT) scans. Herein, we present an automated method for the segmentation of pleural effusion in CT scans based on spatial context information. The method consists of two stages: first, a probabilistic pleural effusion map is created using multi-atlas segmentation. The probabilistic map assigns a priori probabilities to the presence of pleural uid at every location in the CT scan. Second, a statistical pattern classification approach is designed to annotate pleural regions using local descriptors based on a priori probabilities, geometrical, and spatial features. Thirty seven CT scans from a diverse patient population containing confirmed cases of minimal to severe amounts of pleural effusion were used to validate the proposed segmentation method. An average Dice coefficient of 0.82685 and Hausdorff distance of 16.2155 mm was obtained.

The pleural space is a virtual compartment between the lung and chest wall that becomes filled with fluid and inflammatory cells during a variety of respiratory diseases. Here, we study the potential role of the eicosanoid metabolite leukotriene B4 (LTB4) in disparate diseases leading to acute (pneumonia) or chronic (tuberculosis, cancer) inflammation of the pleural space. LTB4 concentrations were significantly higher in pleural fluid due to pneumonia, tuberculosis and cancer with respect to congestive heart failure and correlated with neutrophil elastase, which is used as an indication of state of activation of neutrophils in the pleural space. Moreover, pleural LTB4 was biologically active, as an anti-LTB4 antibody partially neutralized the chemotactic activity of parapneumonic, tuberculous and cancer effusions. Macrophages, neutrophils, lymphocytes, mesothelial cells and cancer cells all expressed mRNA for 5-lipoxygenase, the enzyme that initiates leukotriene synthesis leading to the production of LTB4, in exudative pleural effusions. Upon stimulation in transudative pleural effusions, pleural macrophages produced, in a time-dependent fashion, a significantly higher concentration of LTB4 than mesothelial cells. These studies demonstrate that different cell types are capable of producing LTB4 in the inflamed pleural space and that this mediator may play a crucial role in the recruitment of neutrophils into the pleural space.

The current study presents a case of primary pulmonary lymphoma (PPL) mimicking refractory lung abscess that was diagnosed at autopsy. An 80-year-old male with clinically inapparent aspiration presented with a large cavitated mass and pleural effusion. A lung abscess and empyema was diagnosed, therefore, antibiotics were administered and the pleural effusion was drained. Various examinations, including a biopsy, yielded no specific diagnosis. The lesion was considered inoperable due to the poor general condition of the patient. Subsequently, the mass that had been diagnosed as a refractory lung abscess became enlarged and a repeat biopsy resulted in a diagnosis of diffuse large B-cell lymphoma. The patient succumbed to sudden respiratory failure, and the final diagnosis of PPL was confirmed at autopsy. PPL is a rare disease that accounts for 0.45% of all pulmonary malignant tumors and is difficult to diagnose in inoperable cases. Therefore, patients with PPL who do not undergo surgery can be misdiagnosed and consequently treated inappropriately. PPL should therefore be considered in the differential diagnosis of a refractory lung abscess.

Lymphangiectasia is a congenital or acquired disorder characterized by abnormal, dilated lymphatics with a variable age of presentation. We describe a case of lymphangiectasia with intestinal and pulmonary involvement in an adolescent female, who presented with many of the classic features including chylous pleural effusions, lymphopenia, hypogammaglobinemia, and a protein-losing enteropathy. She also presented with recurrent lower gastrointestinal bleeding, which is infrequently described. The patient did not improve with bowel rest and a low-fat medium-chain triglyceride diet and had little improvement with octreotide acetate therapy. However, she had a clinical response to antiplasmin therapy, trans-4-aminothylcyclohexamine carboxylic acid (tranexamic acid) in terms of serum albumin and gastrointestinal bleeding. She continues to have exacerbations of her condition, as well as persistent lymphopenia and chronic pleural effusions.

Malignant pleural mesothelioma is the most frequent primary neoplasm of the pleura and its incidence is still increasing.This tumor has a strong association with exposure to occupational or environmental asbestos, often after a long latent period of 30-40 years.Plain chest radiography (CXR) is usually the first-line radiologic examination, but the radiographic findings are nonspecific due to its limited contrast resolution and they need to be complemented by other imaging modalities such as computed tomography (CT), magnetic resonance Imaging (MRI), Positron emission tomography-computed tomography (PET-CT) and ultrasound (US).The aim of this paper is to describe the imaging  features of this malignancy, underlining the peculiarity of CXR, CT, MRI, PET-CT and US and also focusing on diagnostic workup, based on the literature evidence and according to our experience.

Breast implant capsule-associated squamous cell carcinoma: a report of 2 cases.

The use of prosthetic implants for breast augmentation has become commonplace. Although implants do not increase the risk of conventional mammary carcinoma, they are rarely associated with anaplastic large cell lymphoma. We report 2 cases of breast implant capsule-associated squamous cell carcinoma with poor clinical outcomes. Both patients (56-year-old woman and 81-year-old woman) had long-standing implants (>25 years) and presented with acute unilateral breast enlargement. In both cases, squamous cell carcinoma arose in (focally dysplastic) squamous epithelium-lined breast implant capsules and widely invaded surrounding breast parenchyma or chest wall. Neither patient had evidence of a primary mammary carcinoma or squamous cell carcinoma at any other anatomic site. Within 1 year, one patient developed extensive, treatment-refractory, locoregional soft tissue metastasis, and the second patient developed hepatic and soft tissue metastases and died of disease. There are 2 prior reported cases of implant-associated squamous cell carcinoma in the plastic surgery literature; one provides no pathologic staging or outcome information, and the second case was a capsule-confined squamous cell carcinoma. Together, all 4 cases share notable commonalities: the patients had long-standing breast implants and presented with acute unilateral breast pain and enlargement secondary to tumors arising on the posterior aspect of squamous epithelialized implant capsules. Because of both its rarity and its unusual clinical presentation, implant capsule-associated squamous cell carcinoma may be underrecognized. The aggressive behavior of the tumors in this series underscores the importance of excluding malignancy in patients with long-standing breast implants who present with acute unilateral breast pain and enlargement.

Pleural effusion is rarely observed in patients with multiple myeloma (MM). Myeloma cell infiltration or invasion to the pleura is very rare. This study aimed to investigate the clinical characteristics of pleural effusion in patients with MM. We retrospectively reviewed the medical records of patients diagnosed with pleural effusion, MM, and pleural effusion with MM between 2004 and 2014 at Beijing Jishuitan Hospital. The present study included patients with pleural effusion who underwent cytological, bacteriological, biochemical and other testing. The cytopathology of abnormal pleural effusion cells was not diagnostic, thus flow cytometry was performed. MM was defined using the diagnosis standard of NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) 2014 for MM. This study included 3,480 pleural effusion patients and 319 MM patients. There were 34 patients with both MM and pleural effusion (17 men and 17 women). The average age was 63 years (range, 48-84 years). Pleural effusion with MM was caused by congestive heart disease, chronic renal failure, hypoalbuminemia, pulmonary infarctions, cirrhosis, pulmonary arterial hypertension, parapneumonic effusion, tuberculous pleural effusion, and myelomatous pleural effusion (MPE). The diagnosis of MPE was confirmed by the detection of myeloma cells in the pleural fluid using flow cytometric analyses. There were only 2 MPE cases in our study. The first MPE case was a woman. The first clinical manifestation was pleural effusion, and the diagnosis was non-secretory MM, DSS stage IIIA (Durie-Salmon staging system); ISS stage I (the International Staging System). The second MPE case was a man who was diagnosed with MM IgA-κ, DSS stage IIIA; ISS stage II. The detection rate of MPE was very low. MPE tended to present with yellow exudates and the lack of physical and chemical characteristics. Furthermore, patients with MPE exhibited many yellow nodules on the pleura. These nodules were lobulated and had abundant blood supply. The routine pleural effusion pathological examination had low sensitivity. Flow cytometry may be more useful for improving the detection rate of MPE.

The differential diagnosis of malignant pleural effusion and benign pleural effusion remains a clinical problem. Reactive oxygen species modulator 1 is a novel protein overexpressed in various human tumors. The objective of this study was to evaluate the diagnostic value of joint detection of reactive oxygen species modulator 1 and carcinoembryonic antigen in the differential diagnosis of malignant pleural effusion and benign pleural effusion. One hundred two consecutive patients with pleural effusion (including 52 malignant pleural effusion and 50 benign pleural effusion) were registered in this study. Levels of reactive oxygen species modulator 1 and carcinoembryonic antigen were measured by enzyme-linked immunosorbent assay and radioimmunoassay, respectively. Results showed that the concentrations of reactive oxygen species modulator 1 both in pleural fluid and serum of patients with malignant pleural effusion were significantly higher than those of benign pleural effusion (both p < 0.05). The diagnostic sensitivity and specificity of pleural fluid reactive oxygen species modulator 1 were 61.54% and 82.00%, respectively, with the optimized cutoff value of 589.70 pg/mL. However, the diagnostic sensitivity and specificity of serum reactive oxygen species modulator 1 were only 41.38% and 86.21%, respectively, with the cutoff value of 27.22 ng/mL, indicating that serum reactive oxygen species modulator 1 may not be a good option in the differential diagnosis of malignant pleural effusion and benign pleural effusion. The sensitivity and specificity of pleural fluid carcinoembryonic antigen were 69.23% and 88.00%, respectively, at the cutoff value of 3.05 ng/mL, while serum carcinoembryonic antigen were 80.77% and 72.00% at the cutoff value of 2.60 ng/mL. The sensitivity could be raised to 88.17% in parallel detection of plural fluid reactive oxygen species modulator 1 and carcinoembryonic antigen concentration, and the specificity could be improved to 97.84% in serial detection.

The diagnosis of pleural sarcoidosis using thoracentesis may be less invasive when sarcoidosis is already diagnosed histologically in more than one organ specimen. Here we report the case of a 64-year-old woman with pleural sarcoidosis diagnosed on the basis of an increased CD4/CD8 lymphocyte ratio in pleural effusion fluid obtained by thoracentesis. This case report is important because it highlights the usefulness of the CD4/CD8 lymphocyte ratio in pleural effusion as an indicator of pleural involvement of sarcoidosis. A 64-year-old Japanese woman visited our hospital with an initial symptom of dyspnea on exertion for a period of 4 months. Chest computed tomography showed bilateral hilar and multiple mediastinal lymphadenopathy, multiple small nodular shadows in her bilateral lungs, small nodular shadows along the interlobar pleura, and bilateral pleural effusion. Her serum angiotensin-converting enzyme and soluble interleukin-2 receptor levels were elevated. Histological analysis of a resected subcutaneous nodule, and biopsy specimens from a right mediastinal lymph node and from her right lung revealed non-caseous epithelioid granulomas. Her bronchoalveolar lavage fluid exhibited a predominance of lymphocytes together with an increase in the CD4/CD8 lymphocyte ratio. The lymphocytic predominance and the increased CD4/CD8 lymphocyte ratio were also detected in the right-sided pleural effusion fluid obtained by thoracentesis. We diagnosed sarcoidosis with pleural involvement. Because pleural effusion did not resolve spontaneously and her symptom of dyspnea on exertion worsened, corticosteroid therapy was initiated, which ameliorated the sarcoidosis and the pleuritis. Analysis of the CD4/CD8 lymphocyte ratio in pleural effusion fluid obtained by thoracentesis may be helpful for the diagnosis of pleural sarcoidosis when the diagnosis is already made by histological examination of more than one organ specimen.

Background and Objective Several studies on diagnostic accuracy of pleural N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) for effusions from congestive heart failure (CHF) conclude that pleural NT-pro-BNP is a useful biomarker with high diagnostic accuracy for distinguishing CHF effusions. However, its applicability in critical care settings remains uncertain and requires further investigations. Methods NT-proBNP was measured in pleural fluid samples of a prospective cohort of intensive care unit patients with pleural effusions. Receiver operating characteristic curve analysis was performed to determine diagnostic accuracy of pleural NT-proBNP for prediction of CHF effusions. Results One hundred forty-seven critically ill patients were evaluated, 38 (26%) with CHF effusions and 109 (74%) with non-CHF effusions of various causes. Pleural NT-proBNP levels were significantly elevated in patients with CHF effusions. Pleural NT-pro-BNP demonstrated the area under the curve of 0.87 for diagnosing effusions due to CHF. With a cutoff of 2200 pg/mL, pleural NT-proBNP displayed high sensitivity (89%) but moderate specificity (73%). Notably, 29 (27%) of 109 patients with non-CHF effusions had pleural NT-proBNP levels >2200 pg/mL and these patients were more likely to experience septic shock (18/29 vs. 10/80, P<0.001) or acute kidney injury (19/29 vs. 9/80, P<0.001). Conclusions Among critically ill patients, pleural NT-proBNP measurements remain a useful diagnostic aid in evaluation of pleural effusions. However, patients with non-CHF effusions may exhibit high pleural NT-proBNP concentrations if they suffer from septic shock or acute kidney injury. Accordingly, it is suggested that clinical context should be taken into account when interpreting pleural NT-proBNP values in critical care settings. PMID:25502236

A 75-year-old male was diagnosed with central squamous cell carcinoma of the left lung, who has been given 3-dimensional conformal radiotherapy of total dose with 60 Gy in 30 fractions. Three years later, the tumor relapsed in situ and he received another stereotactic radiotherapy with a total dose of 40 Gy at a margin of planning target volume (PTV) in 10 (5 fractions/week) at 4 Gy/fraction. Gefitinib (250 mg/day) was initiated immediately after radiotherapy. Obstructive atelectasis in the left lung and increased pleural effusion occurred at the fourth month after radiotherapy. As this patient has been detected with deletion in exon 19 of the EGFR gene, gefitinib was continuous administered without interruption. After another 4 months, the atelectasis in the left lung reexpanded significantly. To the best of our knowledge, this is the first report in the literature that EGFR tyrosine kinase inhibitors (EGFR-TKI) reversed the radiation atelectasis of pulmonary in the nonsmall cell lung cancer (NSCLC) patient.

Tuberculous pleuritis remains the commonest cause of exudative effusions in areas with a high prevalence of tuberculosis and histological and/or microbiological confirmation on pleural tissue is the gold standard for its diagnosis. Uncertainty remains regarding the choice of closed pleural biopsy needles. This prospective study compared ultrasound-assisted Abrams and Tru-Cut needle biopsies with regard to their diagnostic yield for pleural tuberculosis. 89 patients (54 men) of mean ± SD age 38.7 ± 16.7 years with pleural effusions and a clinical suspicion of tuberculosis were enrolled in the study. Transthoracic ultrasound was performed on all patients, who were then randomly assigned to undergo ≥ 4 Abrams needle biopsies followed by ≥ 4 Tru-Cut needle biopsies or vice versa. Medical thoracoscopy was performed on cases with non-diagnostic closed biopsies. Histological and/or microbiological proof of tuberculosis on any pleural specimen was considered the gold standard for pleural tuberculosis. Pleural tuberculosis was diagnosed in 66 patients, alternative diagnoses were established in 20 patients and 3 remained undiagnosed. Pleural biopsy specimens obtained with Abrams needles contained pleural tissue in 81 patients (91.0%) and were diagnostic for tuberculosis in 54 patients (sensitivity 81.8%), whereas Tru-Cut needle biopsy specimens only contained pleural tissue in 70 patients (78.7%, p=0.015) and were diagnostic in 43 patients (sensitivity 65.2%, p=0.022). Ultrasound-assisted pleural biopsies performed with an Abrams needle are more likely to contain pleura and have a significantly higher diagnostic sensitivity for pleural tuberculosis.

INTRODUCTION Primary Pulmonary Mucinous Cystadenocarcinoma PPMC is an extremely rare subtype of pulmonary adenocarcinoma, with only a few dozen cases reported in the literature to date. PRESENTATION OF CASE We report a extremely rare case of pulmonary mucinous cystadenocarcinoma presenting as a pleural mesothelioma. 53-year-old man exposed to asbestos, he is admitted in hospital with a 5 cm mass in right pleura. He was treated by wedge resection. Sparse groups of malignant cells were microscopically observed in pools of mucin. The postoperative histopathological findings were in accordance with the diagnosis of pulmonary mucinous cystadenocarcinoma on cystic adenoid malformation of lung. 5 years later, the patient has no recurrence. DISCUSSION PPMC is usually asymptomatic; hemoptysis is seen occasionally. Preoperative diagnosis is very difficult to establish. Both FNA cytology and transbronchial lung biopsy seem inadequate. Our patient went on to undergo open lung biopsy and histopathological testing that confirmed the diagnosis of PMC. CONCLUSION It is important to differentiate this rare pathological feature of the lung from other lung tumors as the treatment is surgical rather than medical. Thoracic surgeons should bear in mind this rare tumor for the differential diagnosis of a pleural mesothelioma because this tumor has a favorable prognosis. PMID:24055913

Despite similar mechanisms driving pleural fluid accumulation, the causes of pleural effusions in children differ significantly from that of adults. When a pleural effusion re-occurs in an adult, literature recommends early thoracentesis, and consideration for pleuroscopy with biopsy to guide the diagnostic evaluation. In children, there is a paucity of literature for guiding management of recurrent exudative pleural effusion. We present an unusual pediatric case of uremic pleuritis with recurrent pericardial and exudative pleural effusions. © 2017 Wiley Periodicals, Inc.

Pleural effusion is a rare complication in non-tuberculous mycobacterial infection. We report a case of Mycobacterium intracellulare pleuritis with idiopathic pulmonary fibrosis in a 69-year-old man presenting with dyspnea. Pleural effusion revealed lymphocyte dominant exudate. M. intracellulare was identified using a polymerase chain reaction-restriction fragment length polymorphism method and liquid cultures of pleural effusion and pleural biopsy. After combination therapy for M. intracellulare pulmonary disease, the patient was clinically well at a 1-month follow-up.

The breast is an extremely rare target organ for metastasis of extramammary neoplasms. The occurence varies between 1.7% to 6.6% in autopsies; between 1.2% and 2% in clinical cases; and around 2.7% in sputum series. In accordance with the primary tumor localization, it is more common to find metastases of lymphoma, melanoma, rhabdomyosarcoma, tumors of the lung and ovarian tumors. Breast metastasis of the uterine cervix is a very seldomly found. According to the published literature so far there have been around 30 documented cases with such pathology. This study presents the case of a 48-year-old female with a squamous cell carcinoma of the uterine cervix, which was histologically verified in 2010. Three years after the initial tumor diagnosis, radiotherapy and chemotherapy, the patient was found to have a cystic tumor formation in one of her breasts. The formation was painful to pressure. Quadrantectomy with an open bisopsy was performed to the patient. Histological and immunohistochemical diagnosis rejected primary squamous cell carcinoma of the breast. The differential diagnosis of metastatic lesions in the breast is problematic and requires careful clinical history, immunohistochemical study and multidisciplinary approach in the management. Mammary metastases are a bad predictor and they serve as an indicator of generalized dissemination of the primary tumor process.

The small protein, HSPC300 (haematopoietic stem/progenitor cell protein 300), is associated with reorganization of actin filaments and cell movement, but its activity has not been reported in human cancer cells. Here, we investigated the association of HSPC300 expression with clinical features of lung squamous cell carcinoma. High levels of HSPC300 protein were detected in 84.1% of tumour samples, and in 30.8% of adjacent morphologically normal tissues. The number of primary tumours with elevated HSPC300 levels was significantly higher in primary tumours with lymph node metastases as opposed to those without, and also in tumours from patients with more advanced disease. HSPC300 modulates the morphology and motility of cells, as siRNA knockdown caused the reorganization of actin filaments, decreased the formation of pseudopodia, and inhibited the migration of a lung cancer cell line. We further showed that HSPC300 interacted with the WAVE2 protein, and HSPC300 silencing resulted in the degradation of WAVE2 in vitro. HSPC300 and WAVE2 were co-expressed in approximately 85.7% of primary tumours with lymph node metastases. We hypothesize that HSPC300 is associated with metastatic potential of lung squamous cell carcinoma through its interaction with WAVE2.

To establish a high-performance liquid chromatography (HPLC)-based method for determining isoniazide concentration in pleural effusion and plasma of patients with tuberculous pleurisy, and evaluate the permeability of isoniazide from blood into pleural effusion. We collected pleural effusion from 15 patients with tuberculous pleurisy 2 h after administration 300 mg isoniazide in the morning of day 1. Pleural effusion and plasma were obtained 2 h after isoniazide administration on day 3. Isoniazide concentration was measured using HPLC, and the penetration rate of isoniazide in pleural effusion was calculated. Isoniazide concentration in the pleural effusion averaged 1.156∓1.190 µg/ml in the 15 patients at 2 h after isoniazide administration on day 1. On day 3, isoniazide concentration was 1.920∓1.294 µg/ml in the pleural effusion and 2.445∓1.463 µg/ml in the plasma, and the mean penetration rate of isoniazide from blood into the pleural effusion was 86.0%. As isoniazide has a high penetration rate into the pleural effusion in most patients, continuous oral administration of isoniazid has been sufficient to achieve an effective treatment concentration, and intrapleural injection of isoniazide may seem unnecessary for non-drug-resistant tuberculosis pleurisy.

We investigated the role of F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) for the differential diagnosis of malignant and benign pleural effusion. We studied 36 consecutive patients with histologically proven cancer (excluding malignant mesothelioma) who underwent FDG-PET/CT for suspected malignant pleural effusion. Fourteen patients had cytologically proven malignant pleural effusion and the other 22 patients had either negative cytology or clinical follow-up, which confirmed the benign etiology. We examined the maximum standardized uptake values (SUV max) of pleural effusion and the target-to-normal tissue ratio (TNR), calculated as the ratio of the pleural effusion SUV max to the SUV mean of the normal tissues (liver, spleen, 12th thoracic vertebrae [Th12], thoracic aorta, and spinalis muscle). We also examined the size and density (in Hounsfield units) of the pleural effusion and pleural abnormalities on CT images. TNR (Th12) and increased pleural FDG uptake compared to background blood pool were significantly more frequent in cases with malignant pleural effusion (P < 0.05 for both). The cutoff TNR (Th12) value of >0.95 was the most accurate; the sensitivity, specificity, and accuracy for this value were 93%, 68%, and 75%, respectively. FDG-PET/CT can be a useful method for the differential diagnosis of malignant and benign pleural effusion.

We developed a method that used Alcian blue bound to hyaluronan to measure pleural hyaluronan in rabbits postmortem. Rabbits were killed, then ventilated with 21% O2--5% CO2--74% N2 for 3 h. The pleural liquid was removed by suction and 5 ml Alcian blue stock solution (0.33 mg/ml, 3.3 pH) was injected into each chest cavity. After 10 min, the Alcian blue solution was removed and the unbound Alcian blue solution (supernatant) separated by centrifugation and filtration. The supernatant transmissibility (T) was measured spectrophotometrically at 613 nm. Supernatant Alcian blue concentration (Cab) was obtained from a calibration curve of T versus dilutions of stock solution Cab. Alcian blue bound to pleural tissue hyaluronan was obtained by subtracting supernatant Cab from stock solution Cab. Pleural tissue hyaluronan was obtained from a calibration curve of hyaluronan versus Alcian blue bound to hyaluronan. Compared with control rabbits, pleural tissue hyaluronan (0.21 +/- 0.04 mg/kg) increased twofold, whereas pleural liquid volume decreased by 30% after 3 h of ventilation. Pleural effusions present 3 h postmortem without ventilation did not change pleural tissue hyaluronan from control values. Thus ventilation-induced pleural liquid shear stress, not increased filtration, was the stimulus for the increased hyaluronan produced from pleural mesothelial cells.

Objective: To evaluate the usefullness of flexible esophagoscopy and chromoendoscopy with Lugol's solution in the detection of synchronous esophageal neoplasm in patients with hypopharyngeal squamous cell carcinoma (HSCC). Methods: A retrospective review of 96 cases with HSCC that received surgical treatment from March 2016 to March 2017 was accomplished. In these patients, the site of origin were pyriform sinus ( n =75), posterior pharyngeal wall ( n =11) and postcricoid ( n =10). Esophagoscopy was prospectively performed on all patients before treatment for HSCC. All patients underwent conventional white-light endoscopic examination with Lugol chromoendoscopy and narrow band image. Suspicious areas of narrow band image or Lugol-voiding lesions were observed and biopsied. The treatment strategy of primary HSCC was modified according to the presence of synchronous esophageal squamous cell neoplasms by a multidisciplinary approach. Results: Ninety-six patients were enrolled (age ranging from 37-80 years). All patients did not have previous treatment.Histopathological analysis revealed middle to high-grade dysplasia in 5 cases, Tis cancer in 5 cases, cancer in 16 cases and inflammation or normal findings in the others. Four cases were treated with endoscopic submucosal dissection before hypopharygeal surgery, 3 cases with lower esophageal cancers were treated with gastric pull-up combined with free jejunal flap after total circumferential pharyngolaryngectomy (TCPL) and certical esophagectomy, and 14 cases were treated with TCPL, total esophagectomy and gastric pull-up. Conclusions: Esophagoscopy is a feasible and justified procedure in HSCC cases as it enhances the detection of premalignant lesion or second primary cancer. Routine esophagoscopy for detecting synchronous second primary tumor should be recommended for patients with HSCC. The treatment strategy for primary HSCC is modified according to the presence of synchronous second primary tumor.

To determine the rate of subsequent primary site failure in patients with head and neck squamous cell carcinoma of unknown primary (UKP HNSCC) in a region with a high prevalence of cutaneous squamous cell carcinoma, according to a pre-determined institutional policy. Secondary aims included regional and distant control, and overall survival. Patients presenting between April 2005 and June 2016 to the Princess Alexandra Hospital Head and Neck Multidisciplinary Meeting with UKP HNSCC from either presumed mucosal or cutaneous sites treated with curative intent were eligible. Patients with presumed mucosal origin were treated with radiation therapy (RT) with or without chemotherapy, while patients with presumed cutaneous SCC were treated with surgery and post-operative RT with or without chemotherapy. A total of 63 patients met the inclusion criteria. Median follow up duration was 3.9 years (IQR 2.07-5.14). There were no subsequent primary site failures. The rate of nodal failure among presumed mucosal patients was 11.5%, and 8.1% among presumed cutaneous patients. The rate of distant metastatic failure was 11.1% among all patients. The estimated 5 year overall survival was 71.2% (95% CI 59.2-85.7%). Treatment according to our pre-defined institutional policy for UKP HNSCC in a region with a high prevalence of cutaneous SCC appears to be safe and effective with low rates of mucosal primary emergence and nodal failure.

Image-guided sampling of the thickened pleura is a sensitive approach in patients with malignant pleural mesothelioma with pleural effusion. Malignant pleural mesothelioma presenting without effusion however is more of a diagnostic challenge. In this study we report the diagnostic yield and complications of ultrasound-guided cutting needle biopsies in this particular category of patients. A retrospective database analysis from September 2007 until January 2012 was performed in 56 patients with malignant pleural mesothelioma. Clinical characteristics and results of diagnostic evaluations were analysed. Of the 56 patients with malignant pleural mesothelioma, 20 patients presented without pleural effusion of with locular effusion. Ultrasound-guided cutting needle biopsy was performed in 14/20 patients with a diagnostic accuracy of 80%. Only 1 patient had mild haemoptysis immediately following biopsies. Diagnosing patients with pleural thickenings suspect for malignant mesothelioma without pleural effusion or with loculated pleural effusion is effective and safe with ultrasound-guided cutting needle biopsies.

Pleural biomarkers allowing to mini-invasively discriminate benign from malignant pleural effusions are needed. Among potential candidates, microparticles (MPs) are extracellular vesicles that vectorize antigen derived from the parent cell. We hypothesized that tumor-derived MPs could be present in the pleural liquid and help to identify patients with malignant pleural effusions. Using highly sensitive flow cytometry and cryo-electron microscopy, we showed that large amounts of MPs from hematopoïetic and vascular origin could be detectable in pleural fluids. Their level did not differ between benign (n = 14) and malignant (n = 71) pleural effusions. Analysis of selected tumoral associated antigens (podoplanin, mucin 1 and EpCAM, epithelial-cell-adhesion-molecule) evidenced for the first time the presence of tumor-derived MPs expressing EpCAM in malignant pleural fluids only (Specificity = 93%, Sensitivity = 49% and 45% for flow cytometry and ELISA, respectively). The detection of EpCAM-positive-MPs (EpCAM + MPs) by flow cytometry showed a better specificity and sensitivity than ELISA to distinguish between pleural carcinoma and the others malignant pleural effusions (MPE; Sp: 96% vs 89%; Se: 79% vs 66%). Combining EpCAM+ MPs and cytology improved the diagnosis of MPE compared to cytology alone. This study establishes the basis for using EpCAM+ MPs as a promising new biomarker that could be added to the armamentarium to mini-invasively identify patients with malignant pleural effusions.

Pleural effusion, an accumulation of fluid in the pleural space, usually occurs in patients when the rate of fluid formation exceeds the rate of fluid removal. The differential diagnosis of tuberculous pleurisy and malignant pleural effusion is a difficult task in high tuberculous prevalence areas. The aim of the present study was to identify novel biomarkers for the diagnosis of pleural fluid using proteomics technology. We used samples from five patients with transudative pleural effusions for internal standard, five patients with tuberculous pleurisy, and the same numbers of patients having malignant effusions were enrolled in the study. We analyzed the proteins in pleural fluid from patients using a technique that combined two-dimensional liquid-phase electrophoresis and matrix assisted laser desorption/ionization-time of flight-mass spectrometry. We identified a total of 10 proteins with statistical significance. Among 10 proteins, trasthyretin, haptoglobin, metastasis-associated protein 1, t-complex protein 1, and fibroblast growth factor-binding protein 1 were related with malignant pleural effusions and human ceruloplasmin, lysozyme precursor, gelsolin, clusterin C complement lysis inhibitor, and peroxirexdoxin 3 were expressed several times or more in tuberculous pleural effusions. Highly expressed proteins in malignant pleural effusion were associated with carcinogenesis and cell growth, and proteins associated with tuberculous pleural effusion played a role in the response to inflammation and fibrosis. These findings will aid in the development of novel diagnostic tools for tuberculous pleurisy and malignant pleural effusion of lung cancer. © Copyright: Yonsei University College of Medicine 2017

To assess gene expression changes associated with tumor progression in patients with squamous cell carcinoma of the oral cavity. A microarray containing 17 840 complementary DNA clones was used to measure gene expression changes associated with tumor progression in 9 patients with squamous cell carcinoma of the oral cavity. Samples were taken for analysis from the primary tumor, nodal metastasis, and "normal" mucosa from the patients' oral cavity. Tertiary care facility. Patients Nine patients with stage III or stage IV untreated oral cavity squamous cell carcinoma. Our analysis to categorize genes based on their expression patterns has identified 140 genes that consistently increased in expression during progression from normal tissue to invasive tumor and subsequently to metastatic node (in at least 4 of the 9 cases studied). A similar list of 94 genes has been identified that decreased in expression during tumor progression and metastasis. We validated this gene discovery approach by selecting moesin (a member of the ezrin/radixin/moesin [ERM] family of cytoskeletal proteins) and one of the genes that consistently increased in expression during tumor progression for subsequent immunohistochemical analysis using a head and neck squamous cell carcinoma tissue array. A distinct pattern of gene expression, with progressive up- or down-regulation of expression, is found during the progression from histologically normal tissue to primary carcinoma and to nodal metastasis.

Sonographic evaluation of unexplained pleural exudate: a prospective case series.

PubMed

Marcun, Robert; Sustic, Alan

2009-01-01

Thoracic ultrasound may be helpful in differentiating between malignant and tuberculosis-associated pleural exudate. This study aimed to evaluate its utility in patients with unexplained pleural exudate. Consecutive patients were screened and pleural effusion was found in 278 patients. Pleural exudate was present in 106 patients and remained undiagnosed after biochemical and cytological evaluation in 40 patients (median age 58 years, 67% men) who then underwent detailed thoracic ultrasound for the presence of complex (septated or fibrous) or anechoic patterns. Pleural needle biopsy or thoracoscopy with histological evaluation were used for definitive diagnosis. History, clinical characteristics and routine procedures including cytology were not helpful in differential diagnosis. Pleural specimens for histological evaluation were obtained from all 40 patients and confirmed tuberculosis in 12 patients, cancer in nine and nonspecific pleuritis in 19. Sonographic finding of a complex septal pattern was present only in patients with tuberculosis (positive predictive value 100%); anechoic appearance was suggestive of nonspecific pleuritis (positive predictive value 65%). Thoracic ultrasound is a useful bedside method for differentiation of the etiology of pleural exudate. When a complex septal pattern is found, pleural needle biopsy should be the next diagnostic procedure, whereas with less complex pleural sonography findings other methods should be pursued.

Pleural function and lymphatics.

The pleural space plays an important role in respiratory function as the negative intrapleural pressure regimen ensures lung expansion and in the mean time maintains the tight mechanical coupling between the lung and the chest wall. The efficiency of the lung-chest wall coupling depends upon pleural liquid volume, which in turn reflects the balance between the filtration of fluid into and its egress out of the cavity. While filtration occurs through a single mechanism passively driving fluid from the interstitium of the parietal pleura into the cavity, several mechanisms may co-operate to remove pleural fluid. Among these, the pleural lymphatic system emerges as the most important one in quantitative terms and the only one able to cope with variable pleural fluid volume and drainage requirements. In this review, we present a detailed account of the actual knowledge on: (a) the complex morphology of the pleural lymphatic system, (b) the mechanism supporting pleural lymph formation and propulsion, (c) the dependence of pleural lymphatic function upon local tissue mechanics and (d) the effect of lymphatic inefficiency in the development of clinically severe pleural and, more in general, respiratory pathologies. © 2012 The Authors Acta Physiologica © 2012 Scandinavian Physiological Society.

In the strict sense, the parietal pleura is composed of a single layer of mesothelial cells and a uniform layer of loose, irregular connective tissue (about 23 micron in width) subjacent to the mesothelial cells. The parietal pleural blood vessels are 10-15 micron from the pleural space. Tracer substances put in the pleural space are removed at specific locations. Colloidal carbon and chick red blood cells are cleared by the parietal pleural lymphatics located over the intercostal spaces at the caudal end of the thoracic wall and over the lateral sides of the pericardial sac. In these areas the mesothelial cells have specialized openings, the stomata, that directly communicate with the underlying lymphatic lacunae. Cells and particulate matter in the pleural space are cleared only by the parietal pleural lymphatics. Compared to the visceral pleura, we believe the thinness of the parietal pleura, the closeness of its blood vessels to the pleural space, and its specialized lymphatic clearance pathways, together indicate that the parietal pleura plays a major role in pleural liquid and protein dynamics in sheep.

Penile, vulvar and anal squamous cell carcinomas (SCCs) share histomorphological overlap and are prone to lymphatic dissemination into inguinal nodes. Anal SCCs might derive from the anorectal zone (ARZ), anal transitional zone, squamous zone or from perianal skin. These anatomically distinct zones differ in terms of their embryological development. We sought to investigate the role of caudal-related homeobox 2 (CDX2), a homeobox gene implicated in the development and anterior/posterior pattern specification from duodenum to rectum including the ARZ, in terms of narrowing the possible sites of origin to be considered in the setting of SCC with unknown primary presenting with histologically confirmed inguinal lymph node metastasis. By immunohistochemistry (IHC) employing a panel of antibodies directed against CK5/6, CK7, CK20, p63, p16, CEA and CDX2, we compared 89 penile, 11 vulvar and eight anal SCCs with respect to their staining profiles. Moreover, anal SCCs were subjected to in situ hybridisation (ISH) for high-risk human papillomavirus (HPV) subtypes. By IHC, CDX2 expression was observed in 2/8 anal SCCs (25%) while being absent from all penile and vulvar SCCs examined. High-risk HPV subtypes were detected by ISH in all anal SCCs examined, which were uniformly p16-positive by IHC. CDX2 might be valuable in terms of narrowing the possible sites of origin to be considered in the setting of SCC with unknown primary presenting with inguinal lymph node metastasis. However, despite its favourable specificity, the diagnostic benefit achieved by this observation is limited by the low sensitivity.

Lung adenocarcinoma can easily cause malignant pleural effusion which was difficult to discriminate from benign pleural effusion. Now there was no biomarker with high sensitivity and specificity for the malignant pleural effusion. This study used proteomics technology to acquire and analyze the protein profiles of the benign and malignant pleural effusion, to seek useful protein biomarkers with diagnostic value and to establish the diagnostic model. We chose the weak cationic-exchanger magnetic bead (WCX-MB) to purify peptides in the pleural effusion, used matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) to obtain peptide expression profiles from the benign and malignant pleural effusion samples, established and validated the diagnostic model through a genetic algorithm (GA) and finally identified the most promising protein biomarker. A GA diagnostic model was established with spectra of 3930.9 and 2942.8 m/z in the training set including 25 malignant pleural effusion and 26 benign pleural effusion samples, yielding both 100 % sensitivity and 100 % specificity. The accuracy of diagnostic prediction was validated in the independent testing set with 58 malignant pleural effusion and 34 benign pleural effusion samples. Blind evaluation was as follows: the sensitivity was 89.6 %, specificity 88.2 %, PPV 92.8 %, NPV 83.3 % and accuracy 89.1 % in the independent testing set. The most promising peptide biomarker was identified successfully: Isoform 1 of caspase recruitment domain-containing protein 9 (CARD9), with 3930.9 m/z, was decreased in the malignant pleural effusion. This model is suitable to discriminate benign and malignant pleural effusion and CARD9 can be used as a new peptide biomarker.

BACKGROUND Dasatinib, a highly potent BCR-ABL inhibitor, is an effective treatment for patients with chronic myeloid leukemia in chronic phase (CML CP) after resistance, suboptimal response, or intolerance to prior imatinib. In a phase 3 dose optimization trial in patients with CML CP (CA180-034), the occurrence of pleural effusion was significantly minimized with dasatinib 100 mg once daily (QD) compared with other treatment arms (70 mg twice daily [twice daily], 140 mg QD, or 50 mg twice daily). METHODS To investigate the occurrence and management of pleural effusion during dasatinib treatment, and efficacy in patients with or without pleural effusion, data from CA180-034 were analyzed. RESULTS With 24-month minimum follow-up, 14% of patients treated with dasatinib 100 mg QD incurred pleural effusion (grade 3: 2%; grade 4: 0%) compared with 23% to 26% in other study arms. The pleural effusion rate showed only a minimal increment from 12 to 24 months. In the 100 mg QD study arm, median time to pleural effusion (any grade) was 315 days, and after pleural effusion, 52% of patients had a transient dose interruption, 35% had a dose reduction, 57% received a diuretic, and 26% received a corticosteroid. Three patients in the 100 mg QD study arm discontinued treatment after pleural effusion. Across all study arms, patients with or without pleural effusion demonstrated similar progression-free and overall survival, and cytogenetic response rates were higher in patients with a pleural effusion. CONCLUSIONS Pleural effusion is minimized with dasatinib 100 mg QD dosing and its occurrence does not affect short- or long-term efficacy. PMID:19924787

Management of pleural effusions is a common diagnostic and management problem. We reviewed the outcomes from pleural procedures after the instigation of pleural effusion management guidelines, focusing on pleural ultrasound and a hands-on teaching programme followed by procedure supervision that enabled many operators to perform such procedures. This is a retrospective analysis of all procedures performed for pleural effusions on medical patients. Outcomes were assessed prior to the instigation of pleural effusion management guidelines (pleural pathway) and hands-on teaching (January 2010 to June 2011) and following these interventions (January 2012 to June 2013). A total of 171 procedures involving 129 patients (pre-pathway group) and 146 procedures involving 115 patients (post-pathway group) was analysed. The rate of complications prior to the pleural pathway was 22.2% (38 of 171 procedures). Following the pathway, the rate of complications declined to 7.5% (11 of 146 procedures, P < 0.003). The use of pleural ultrasound increased dramatically (72.5 vs 90.2%). The number of patients who underwent repeated procedures (defined as ≥3) reduced dramatically (21 vs 7, P < 0.01). This improvement occurred using many supervised operators who completed the hands-on teaching programme (n = 32) and followed the pleural pathway (127 of 146 procedures). The instigation of a clinical pathway focused on the use of bedside pleural ultrasound, and teaching of drainage techniques with procedure supervision vastly improved patient outcomes. This not only allowed better quality of care for patients, it also provided the acquisition of new skills to medical staff, not limiting these skills to specialised staff. © 2017 Royal Australasian College of Physicians.

To determine the frequency and investigate possible mechanisms and prognostic relevance of minimal (<10-mm thickness) pleural effusion in patients with small cell lung cancer (SCLC). The single-center retrospective study was approved by the institutional review board of the hospital, and informed consent was waived by the patients. A cohort of 360 consecutive patients diagnosed with SCLC by using histologic analysis was enrolled in this study. Based on the status of pleural effusion on chest computed tomographic (CT) scans at diagnosis, patients were classified into three groups: no pleural effusion, minimal pleural effusion, and malignant pleural effusion. Eighteen variables related to patient, environment, stage, and treatment were included in the final model as potential confounders. Minimal pleural effusion was present in 74 patients (20.6%) and malignant pleural effusion in 83 patients (23.0%). Median survival was significantly different in patients with no, minimal, or malignant pleural effusion (median survival, 11.2, 5.93, and 4.83 months, respectively; P < .001, log-rank test). In the fully adjusted final model, patients with minimal pleural effusion had a significantly increased risk of death compared with those with no pleural effusion (adjusted hazard ratio, 1.454 [95% confidence interval: 1.012, 2.090]; P = .001). The prognostic effect was significant in patients with stage I-III disease (adjusted hazard ratio, 2.751 [95% confidence interval: 1.586, 4.773]; P < .001), but it disappeared in stage IV disease. An indirect mechanism representing mediastinal lymphadenopathy was responsible for the accumulation in all but one patient with minimal pleural effusion. Minimal pleural effusion is a common clinical finding in staging SCLC. Its presence is associated with worse survival in patients and should be considered when CT scans are interpreted. © RSNA, 2015.

To report the results of patients undergoing combined excision, cryotherapy, and intraoperative mitomycin-C (EXCRIM) for primary ocular surface squamous neoplasia (OSSN) METHODS: A retrospective review of a non-comparative interventional case series. Histopathologically confirmed primary localized (less than four clock hours) OSSN treated with EXCRIM using adjuvant 0.02 % mitomycin-C (MMC) were included in the study. The main outcome measures were recurrence and complications related to MMC. The study enrolled 28 eyes of 28 patients with OSSN with a median age of 64.5 (range 43 to 84) years. The mean tumor size was 6.9 × 4.35 mm. There was corneal involvement in 23 of 28 (82 %). Seven patients (21 %) had delayed epithelial healing. Two of eight patients (25 %) with squamous cell carcinoma (SCC) had positive lateral margins. There were no recurrences over a mean follow-up of 49 months (range 24 to 96). The excision of OSSN combined with cryotherapy and intraoperative MMC is effective with a low recurrence rate. Long-term follow-up yielded favorable results.

Management of Patients With Adenocarcinoma or Squamous Cancer of the Esophagus.

Esophageal cancer is characterized by early and frequent metastasis. Surgery is the primary treatment for early-stage disease, whereas patients with patients with locally advanced disease receive perioperative chemotherapy or chemoradiotherapy. Squamous cancers can be treated with primary chemoradiotherapy without surgery, depending on their response to therapy and patient tolerance for subsequent surgery. Chemotherapy with a fluorinated pyrimidine and a platinum agent, followed by later treatment with taxanes and irinotecan, provides some benefit. Agents that inhibit the erb-b2 receptor tyrosine kinase 2 (ERBB2 or HER2), or vascular endothelial growth factor, including trastuzumab, ramucirumab, and apatinib, increase response and survival times. Esophageal adenocarcinomas have mutations in tumor protein p53 and mutations that activate receptor-associated tyrosine kinase, vascular endothelial growth factor, and cell cycle pathways, whereas esophageal squamous tumors have a distinct set of mutations. Esophageal cancers develop systems to evade anti-tumor immune responses, but studies are needed to determine how immune checkpoint modification contributes to esophageal tumor development.

This study evaluates the oncological outcome of patients with recurrent oropharyngeal squamous cell carcinoma (OPSCC) after primary radiation therapy +/- chemotherapy, primary surgical therapy, and surgical therapy followed by radiation therapy +/- chemotherapy. A total of 156 patients (36%) of a cohort of 427 treated for OPSCC between 1990 and 2006 developed recurrent disease. Fifty-one patients (12%) qualified for salvage treatment. Study endpoints were 5-year overall survival (OS) and disease-specific survival (DSS). The 5-year OS and DSS rates after salvage treatment were 29% and 40%; after initial primary radiation therapy, 25% and 40%; after initial surgery followed by radiation therapy, 40% and 40%; and after initial surgery alone, 20% and 40%. Patients with an advanced OPSCC have a considerable risk for recurrence. Despite poor ultimate outcome, salvage treatment should be attempted in patients with resectable disease, good performance status, and absence of distant metastases. 2009 Wiley Periodicals, Inc.

Primary squamous cell carcinoma (SCC) of ampulla has seldom been reported. However, metastatic SCC to ampulla of Vater is well known. We report a case of primary SCC of ampulla of Vater coexistent with well-differentiated adenocarcinoma of the distal pancreatic duct. A 50-year-old female presented with evidence of obstructive jaundice. Endoscopic retrograde cholangio-pancreatography revealed bulging papilla with ulcero-infiltrative growth at the ampulla of Vater. An initial endoscopic biopsy of the ampullary mass showed a well-differentiated SCC. The patient underwent Whipple's operation. Thorough sampling of the dilated portion of the pancreatic duct showed presence of well-differentiated adenocarcinoma of the distal pancreatic duct. Immunohistochemical study with synaptophysin and chromogranin was done with negative result, ruling out neuroendocrine differentiation. Also, a detailed clinical, endoscopic and radiological examination was carried out, that excluded the presence of primary SCC elsewhere. PMID:22064341

Abstract We investigated the role of F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) for the differential diagnosis of malignant and benign pleural effusion. We studied 36 consecutive patients with histologically proven cancer (excluding malignant mesothelioma) who underwent FDG-PET/CT for suspected malignant pleural effusion. Fourteen patients had cytologically proven malignant pleural effusion and the other 22 patients had either negative cytology or clinical follow-up, which confirmed the benign etiology. We examined the maximum standardized uptake values (SUVmax) of pleural effusion and the target-to-normal tissue ratio (TNR), calculated as the ratio of the pleural effusion SUVmax to the SUVmean of the normal tissues (liver, spleen, 12th thoracic vertebrae [Th12], thoracic aorta, and spinalis muscle). We also examined the size and density (in Hounsfield units) of the pleural effusion and pleural abnormalities on CT images. TNR (Th12) and increased pleural FDG uptake compared to background blood pool were significantly more frequent in cases with malignant pleural effusion (P < 0.05 for both). The cutoff TNR (Th12) value of >0.95 was the most accurate; the sensitivity, specificity, and accuracy for this value were 93%, 68%, and 75%, respectively. FDG-PET/CT can be a useful method for the differential diagnosis of malignant and benign pleural effusion. PMID:26200610

Perineural spread (PNS) of cutaneous squamous cell carcinoma of the head and neck (SCCHN) can be associated with poor outcomes. Disease understanding and awareness is limited leading to delayed diagnosis and treatment. The purpose of this study was to identify epidemiological features of patients with PNS of cutaneous SCCHN. Tumor characteristics and demographics of patients with PNS of cutaneous SCCHN managed through a single institution were collected between 1998 and 2013. One hundred twenty patients were included in this study. The majority had a history of skin cancer (85.8%). The median time from primary tumor treatment to PNS symptom onset was 16 months (range, 1-86 months). A total of 34.2% had no perineural invasion (PNI) detected in the primary, and 22.5% had no known primary tumor. Only 5.8% of the patients had nodal involvement at presentation. Patients can present with PNS from cutaneous SCCHN with no known primary tumor or with primary tumors without PNI. The majority of patients presented without regional nodal involvement. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1416-1420, 2016. © 2016 Wiley Periodicals, Inc.

Fibroblastic osteosarcoma with epithelioid and squamous differentiation in a dog.

A fibroblastic osteosarcoma with epithelioid and squamous differentiation in the distal femur of a 9-y-old spayed female Greyhound dog is described. Grossly, the tumor consisted of a pale-white, firm-to-hard mass that replaced the medullary and cortical areas of the distal end of the right femur. Histologically, the mass was composed predominantly of spindle cells admixed with areas of mineralized and non-mineralized osteoid matrix that were surrounded by stellate osteoblasts and scattered multinucleate giant cells, consistent with the diagnosis of a fibroblastic osteosarcoma. In addition, well-demarcated clusters of neoplastic epithelioid cells and foci of squamous differentiation with keratin pearls were present throughout the neoplasm. The spindle cells, epithelioid cells, and areas of squamous differentiation expressed cytoplasmic immunostaining for osteocalcin and osteonectin. The spindle cells and epithelioid cells were also immunopositive for vimentin. Epithelioid cells also expressed occasional cytoplasmic immunostaining for pancytokeratin (PCK) Lu-5, and areas of squamous differentiation were immunoreactive for PCK Lu-5 and high molecular weight CK; these areas were inconsistently immunoreactive for CK 5-6 and immunonegative for low molecular weight CK. Foci of squamous differentiation were not located within blood or lymphatic vessels, given that no immunoreactivity for factor VIII-related antigen was observed around these areas. A thorough autopsy and an evaluation of the medical history excluded a primary carcinoma or other neoplasm elsewhere in the dog. The findings were consistent with a diagnosis of fibroblastic osteosarcoma with epithelioid and squamous differentiation.

Advanced head and neck squamous cell carcinomas frequently develop distant metastases to limited organs, including the lungs, bone, mediastinal lymph nodes, brain, and liver. Peritoneal carcinomatosis as an initial distant metastasis from hypopharyngeal squamous cell carcinoma is quite rare. A 75-year-old man diagnosed with hypopharyngeal squamous cell carcinoma and his clinical stage was determined as T2N2cM0. Notably, the right retropharyngeal lymph node surrounded more than half of the right internal carotid artery. Concomitant conformal radiation therapy was administered for the primary hypopharyngeal lesion, and the whole neck and tumor response was evaluated at this point according to our algorithm-based chemoradioselection protocol. As the tumor responses at both the primary and lymph nodes were poor, with the right retropharyngeal lymph node in particular demonstrating mild enlargement, we performed a radical surgery: pharyngolaryngectomy, bilateral neck dissection, and reconstruction of the cervical esophagus with a free jejunal flap. Then, postoperative CRT was performed. During these therapies, the patient developed a fever and mild abdominal pain, which was associated with an increased C-reactive protein level. Contrast-enhanced computed tomography from the neck to the pelvis demonstrated mild peritoneal hypertrophy and ascites with no evidence of recurrent and/or metastatic tumor formation. We initially diagnosed acute abdomen symptoms as postoperative ileus. However, cytological examination of the refractory ascites resulted in a diagnosis of peritoneal carcinomatosis. Owing to rapid disease progress, the patient died 1.5 months after abdominal symptom onset. The present case is the second reported case of head and neck squamous cell carcinoma with peritoneal carcinomatosis as an incipient distant metastasis. Therefore, peritoneal carcinomatosis should be considered a differential diagnosis when acute abdomen is noted during treatment for head and neck cancers.

Unexpected diagnosis of synchronous second primary cancers (SPC) complicates physicians' decision-making because clinical details of squamous esophageal cancer (EC) patients with SPC have been limited. We evaluated clinical features and treatment outcomes of patients with synchronous SPC detected during the initial staging of squamous EC. We identified a total of 317 consecutive patients diagnosed with squamous EC. Relevant clinical and cancer-specific information were reviewed retrospectively. EC patients with synchronous SPC were identified in 21 patients (6.6%). There were significant differences in median age (70 years vs. 63 years, p = 0.01), serum albumin level (3.3 g/dL vs. 3.9 g/dL, p < 0.01) and body mass index (20.4 kg/m(2) vs. 22.8 kg/m(2), p = 0.01) between EC patients with and without SPC. Head and neck, lung and gastric cancers accounted for 18.2%, 22.7%, and 18.2% of SPC, respectively. Positron emission tomography-computed tomography (PET-CT) detected four cases (18.2%) of SPC that were missed on CT. Management plans were altered in 13 of 21 patients (61.9%) with detected SPC. Curative esophagectomy was attempted in 28.6% of EC patients with SPC (vs. 59.1% of patients without SPC; p = 0.006). EC patients with SPC had significantly lower 5-year survival than patients without SPC (10.6% vs. 36.7%, p = 0.008). Synchronous SPC were found in 6.6% of squamous EC patients, and PET-CT contributed substantially to the detection of synchronous SPC. EC patients with SPC had poor survival due to challenges of providing stage-appropriate treatment.

Using computed tomography (CT) to rapidly and accurately quantify pleural effusion volume benefits medical and scientific research. However, the precise volume of pleural effusions still involves many challenges and currently does not have a recognized accurate measuring. To explore the feasibility of using 64-slice CT volume-rendering technology to accurately measure pleural fluid volume and to then analyze the correlation between the volume of the free pleural effusion and the different diameters of the pleural effusion. The 64-slice CT volume-rendering technique was used to measure and analyze three parts. First, the fluid volume of a self-made thoracic model was measured and compared with the actual injected volume. Second, the pleural effusion volume was measured before and after pleural fluid drainage in 25 patients, and the volume reduction was compared with the actual volume of the liquid extract. Finally, the free pleural effusion volume was measured in 26 patients to analyze the correlation between it and the diameter of the effusion, which was then used to calculate the regression equation. After using the 64-slice CT volume-rendering technique to measure the fluid volume of the self-made thoracic model, the results were compared with the actual injection volume. No significant differences were found, P = 0.836. For the 25 patients with drained pleural effusions, the comparison of the reduction volume with the actual volume of the liquid extract revealed no significant differences, P = 0.989. The following linear regression equation was used to compare the pleural effusion volume (V) (measured by the CT volume-rendering technique) with the pleural effusion greatest depth (d): V = 158.16 × d - 116.01 (r = 0.91, P = 0.000). The following linear regression was used to compare the volume with the product of the pleural effusion diameters (l × h × d): V = 0.56 × (l × h × d) + 39.44 (r = 0.92, P = 0.000). The 64-slice CT volume-rendering technique can accurately measure the volume in pleural effusion patients, and a linear regression equation can be used to estimate the volume of the free pleural effusion.

Malignant pleural effusion (MPE) is associated with a significant impact on health-related quality of life. Palliative interventions abound, with varying costs and degrees of invasiveness. We examined the relative cost-utility of 5 therapeutic alternatives for MPE among adults. Original studies investigating the management of MPE were extensively researched, and the most robust and current data particularly those from the TIME2 trial were chosen to estimate event probabilities. Medicare data were used for cost estimation. Utility estimates were adapted from 2 original studies and kept consistent with prior estimations. The decision tree model was based on clinical guidelines and authors' consensus opinion. Primary outcome of interest was the incremental cost-effectiveness ratio for each intervention over a less effective alternative over an analytical horizon of 6 months. Given the paucity of data on rapid pleurodesis protocol, a sensitivity analysis was conducted to address the uncertainty surrounding its efficacy in terms of achieving long-term pleurodesis. Except for repeated thoracentesis (RT; least effective), all interventions had similar effectiveness. Tunneled pleural catheter was the most cost-effective option with an incremental cost-effectiveness ratio of $45,747 per QALY gained over RT, assuming a willingness-to-pay threshold of $100,000/QALY. Multivariate sensitivity analysis showed that rapid pleurodesis protocol remained cost-ineffective even with an estimated probability of lasting pleurodesis up to 85%. Tunneled pleural catheter is the most cost-effective therapeutic alternative to RT. This, together with its relative convenience (requiring neither hospitalization nor thoracoscopic procedural skills), makes it an intervention of choice for MPE.

The purpose of this study was to investigate the relationship between pleural temperature and pneumothorax or pleural effusion after radiofrequency (RF) ablation of lung tumors. The pleural temperature was measured immediately outside the lung surface nearest to the tumor with a fiber-type thermocouple during 25 ablation procedures for 34 tumors in 22 patients. The procedures were divided into two groups depending on the highest pleural temperature: P-group I and P-group II, with highest pleural temperatures of <40 deg. C and {>=}40 deg. C, respectively. The incidence of pneumothorax or pleural effusion was compared between the groups. Multiple variables were comparedmore » between the groups to determine the factors that affect the pleural temperature. The overall incidence of pneumothorax and pleural effusion was 56% (14/25) and 20% (5/25), respectively. Temperature data in five ablation procedures were excluded from the analyses because these were affected by the pneumothorax. P-group I and P-group II comprised 10 procedures and 10 procedures, respectively. The incidence of pleural effusion was significantly higher in P-group II (4/10) than in P-group I (0/10) (p = 0.043). However, the incidence of pneumothorax did not differ significantly (p = 0.50) between P-group I (4/10) and P-group II (5/10). Factors significantly affecting the pleural temperature were distance between the electrode and the pleura (p < 0.001) and length of the lung parenchyma between the electrode and the pleura (p < 0.001). We conclude that higher pleural temperature appeared to be associated with the occurrence of pleural effusion and not with that of pneumothorax.« less

Bilious pleural effusion is an extremely rare condition associated with liver diseases, subphrenic or subhepatic abscess formation, biliary peritonitis, and invasive procedures (i.e., percutaneous biliary drainage or liver biopsy). The current diagnostic test is based on the measurement of the ratio of pleural total bilirubin to serum total bilirubin, which is greater than 1 in patients with bilious pleural effusion. Given the low incidence of bilious pleural effusion, the precise diagnostic yield of this ratio based test has not been evaluated. We retrospectively reviewed the medical records of our institution and searched the PubMed database for reports of bilious pleural effusion. We identified a total of 12 cases of bilious pleural effusion (9 from 8 Pubmed reports and 3 from our institutional records). The factors causing this condition were broadly classified into three categories based on the pathophysiology: 1) liver diseases (echinococcosis, tuberculosis and amebiasis); 2) subhepatic/subphrenic abscess or biliary peritonitis, with or without biliary tract obstruction; and 3) iatrogenic disease after percutaneous biliary drainage and/or liver biopsy. The sensitivity of detection was 76.9% when the ratio of pleural total bilirubin to serum total bilirubin was greater than 1. The sensitivity increased to 100% when a combination test including pleural glycoholic acid was adopted. This study demonstrates the high diagnostic yield for bilious pleural effusion using a combination of two test criteria; a ratio of pleural total bilirubin to serum total bilirubin greater than 1 and the presence of pleural glycoholic acid.

Malignant pleural mesothelioma (MPM) is a rare but fatal tumour. Although most MPM patients show pleural effusion at even the early stage, it is hard to diagnose as MPM at the early stage because a sensitive and reliable diagnostic marker for MPM has not been found in plasma or pleural effusion. In this study, we investigated whether intelectin-1 was specifically contained in MPM cells and the pleural effusion of MPM patient by immunohistochemistry, western blotting, and enzyme-linked immunosorbent assay. Malignant pleural mesothelioma cell lines, but not lung adenocarcinoma cell lines, secreted intelectin-1. In immunohistochemistry, epithelioid-type MPMs, but neither pleura-invading lung adenocarcinomas nor reactive mesothelial cells near the lung adenocarcinomas, were stained with anti-intelectin antibodies. Pleural effusion of MPM patients contained a higher concentration of intelectin-1 than that of lung cancer patients. These results suggest that detection of intelectin-1 may be useful for a differential diagnosis of epithelioid-type MPM in immunohistochemistry and that a high concentration of intelectin-1 in pleural effusion can be used as a new marker for clinical diagnosis of MPM.

Recurrent massive pleural effusion due to pleural, pericardial, and epicardial fibrosis in histoplasmosis.

Acute histoplasmosis is generally a benign, self-limited pulmonary infection. Although Histoplasma capsulatum pneumonitis is common, pleural effusions associated with histoplasmosis are quite rare, and massive pleural effusions have not been reported. There have been several reports of pericardial fibrosis secondary to histoplasmosis, but epicardial fibrosis has not been described. We report a biopsy-proven case of histoplasmosis initially associated with recurrent massive pleural effusions and excessive pleural fibrosis causing a trapped lung. The patient later developed constrictive pericarditis. Despite pericardiectomy, severe cor pulmonale occurred, and the patient died. Necropsy demonstrated fibrosis of the epicardium.

A 60-year-old female who was known to have rheumatoid arthritis for the preceding two-and-half years presented with difficulty in breathing associated with chest pain over the right hemithorax of two months duration. She was found to have a right-sided mild to moderate pleural effusion; there was no evidence of pleural thickening. The pleural fluid was pale yellow in appearance and diagnostic work-up confirmed it to be a pseudochylous pleural effusion. The present case highlights the rare occurrence of pseudochylothorax without pleural thickening as a complication of rheumatoid arthritis.

A Systematic Review of the Epidemiology, Immunopathogenesis, Diagnosis, and Treatment of Pleural TB in HIV- Infected Patients

Background. High HIV burden countries have experienced a high burden of pleural TB in HIV-infected patients. Objective. To review the epidemiology, immunopathogenesis, diagnosis, and treatment of pleural TB in HIV-infected patients. Methods. A literature search from 1950 to June 2011 in MEDLINE was conducted. Results. Two-hundred and ninety-nine studies were identified, of which 30 met the inclusion criteria. The immunopathogenesis as denoted by cells and cytokine profiles is distinctly different between HIV and HIV-uninfected pleural TB disease. Adenosine deaminase and interferon gamma are good markers of pleural TB disease even in HIV-infected patients. HIV-uninfected TB suspects with pleural effusions commonly have a low yield of TB organisms however the evidence suggests that in dually infected patients smear and cultures have a higher yield. The Gene Xpert MTB/RIF assay has significant potential to improve the diagnosis of pleural TB in HIV-positive patients. Conclusions. Pleural TB in HIV-infected patients has a different immunopathogenesis than HIV-uninfected pleural TB and these findings in part support the differences noted in this systematic review. Research should focus on developing an interferon gamma-based point of care diagnostic test and expansion of the role of Gene Xpert in the diagnosis of pleural TB. PMID:22474483

Refractory pleural effusion can be a life-threatening complication in patients receiving maintenance hemodialysis. We report successful treatment of refractory pleural effusion using a Denver® pleuroperitoneal shunt in one such patient. A 54-year-old Japanese man, who had previously undergone left nephrectomy, was admitted urgently to our department because of a high C-reactive protein (CRP) level, right pleural effusion, and right renal abscess. Because antibiotics proved ineffective and his general state was deteriorating, he underwent emergency insertion of a thoracic drainage tube and nephrectomy, and hemodialysis was started. Although his general state improved slowly thereafter, the pleural effusion, which was unilateral and transudative, remained refractory and therefore he needed to be on oxygenation. To control the massive pleural effusion, a pleuroperitoneal shunt was inserted. Thereafter, his respiratory condition became stable without oxygenation and he was discharged. His general condition has since been well. Although pleural effusion is a common complication of maintenance hemodialysis, few reports have documented the use of pleuroperitoneal shunt to control refractory pleural effusion. Pleuroperitoneal shunt has been advocated as an effective and low-morbidity treatment for refractory pleural effusion, and its use for some patients with recurrent pleural effusion has also been reported, without any severe complications. In the present case, pleuroperitoneal shunt improved the patient's quality of life sufficiently to allow him to be discharged home without oxygenation. Pleuroperitoneal shunt should be considered a useful treatment option for hemodialysis patients with refractory pleural effusion.

The differential diagnosis of malignant and tuberculous pleural effusion is frequently difficult. The aim of our study is to determine the discrimination value of demographic parameters and different biological markers in pleural fluid. In pleural fluid obtained from 106 patients with tuberculous, 250 with malignant and 218 with miscellaneous pleural effusion, clinical and analytical parameters were analysed, applying polytomous regression analysis and the receiver operating characteristic (ROC) curves. The three groups could be differentiated using the measured markers. Age, tumour necrosing factor-alpha, lactate dehydrogenase (LDH), adenosine deaminase (ADA), C-reactive protein (CRP) and carcinoembryonic antigen (CEA) were significant predictors for discriminating tuberculous from malignant pleural effusions; nucleated cells, lymphocytes, cholesterol, LDH, ADA, CRP, CEA and CA15.3 distinguish between malignant and miscellaneous pleural effusions. The ROC areas (95% confidence interval) were, 0.973 (0.953, 0.992) for tuberculous, 0.922 (0.900, 0.943) for miscellaneous, and 0.927 (0.907, 0.948) for malignant pleural effusion. The polytomous model correctly classified a significantly high proportion of patients with tuberculosis (85.8%) and cancer (81.6%). The incorrect classification rate was 17.8%, which increased to 19.5% in the correction using bootstrap. The results obtained to estimate the probability of tuberculous and malignant pleural effusion confirm that this model achieves a high diagnostic accuracy. This model should be applied to determine which patients with a pleural effusion of unknown origin would not benefit from further invasive procedures. © 2014 John Wiley & Sons Ltd.

Paraneoplastic syndromes of the head and neck are rare. Hypercalcemia and leukocytosis have been described. The literature was reviewed, and a case of a squamous cell carcinoma of the maxilla producing beta human chorionic gonadotropin (beta-HCG) is presented. A 47-year-old white man with a T4N1M0 squamous cell carcinoma of the left maxilla was treated with a maxillectomy and neck dissection for an N1 positive neck. After completing his planned radiotherapy, he developed distant metastases, which included an axillary node that stained positive for human beta-HCG. Retrospective review of the primary specimen showed beta-HCG positivity in an anaplastic component of the tumor along with vascular invasion. The first case in the literature of a paraneoplastic syndrome with beta-HCG production in association with squamous cell carcinoma of the maxilla is presented. This case history fits the aggressive nature of beta HCG producing tumors elsewhere in the body.

Squamous cell carcinoma (SCC) is a rare type of breast malignancy and little is known about long-term outcome. In the present report, the clinical features, histopathologic findings and postoperative course of a patient with squamous cell carcinoma are described. We have treated a 47-years-old woman who admitted for right breast mass without any discharge, bleeding and pain. The tumor was, 3 × 2 × 1.5 cm in size with central abscess formation. The result of surgical biopsy revealed large cell keratinizing type of SCC. The metastatic work-up studies ruled out any other probable sources of primary tumor. The patient was performed modified radical mastectomy and axillary dissection and received two cycles of chemotherapy. Squamous cell carcinoma of the breast (SCCB) is a rare entity and should be considered in patients with rapidly progressing breast mass. It should also be considered in breast lesions with abscess formation. The initial therapeutic approach should be surgical excision after histopathological diagnosis.

Breast and splenic metastases of squamous cell carcinoma from the uterine cervix: a case report

PubMed Central

2014-01-01

Introduction Metastases to the breast from extramammary malignancies are infrequent, the most common primary sites are malignant melanoma, leukemia, lymphoma, and cancer of the lung, stomach, prostate and ovary. The cervical origin is exceptional. Splenic metastasis from squamous cell carcinoma of the cervix is also rare. To the best of our knowledge, only three cases of isolated splenic metastasis have been reported in the literature. Case presentation We describe the case of a 55-year-old North African woman who presented with a nodule in her left breast eight months after treatment for stage IIB squamous cell uterine cervical carcinoma. The excisional biopsy with histological study demonstrated a poorly differentiated squamous cell carcinoma. A computed tomography scan revealed a splenic secondary location. Conclusions We report here a case of two unusual metastatic sites of uterine cervical carcinoma, the breast and spleen. It is the first case of this association without widespread disease.

1988-01-01

During a cross sectional medical survey of 2815 insulation workers with 30 years or more from onset of asbestos exposure conducted from 1981 to 1983, a positive history of benign pleural effusion was found in 20 (0.71%). Two or three such episodes had occurred in four of these 20 subjects. The chest x ray abnormalities in these cases were characterised by pleural fibrosis in 19 and diffuse pleural fibrosis with blunting of the corresponding costophrenic angle in 16. In the total group of 2815 insulation workers diffuse pleural fibrosis was found in 142 (5.0%). Thus diffuse pleural fibrosis with blunting of the corresponding costophrenic angle is a frequent residual abnormality after benign pleural effusion. Its impact on pulmonary function can be pronounced. Images PMID:3260799

Chronic pleuritic pain in four patients with asbestos induced pleural fibrosis.

PubMed Central

Miller, A

1990-01-01

Four patients occupationally exposed to asbestos, each suffering at least eight years of disabling, persistent, and often bilateral pleuritic pain are described. Radiographic evidence of pleural disease ranged from plaques seen only on computed tomography to typical bilateral plaques or diffuse thickening to extensive diffuse and circumscribed pleural fibrosis and calcification. There was no history or evidence of acute pleuritis or pleural effusion in three patients. Intermittent pleural friction rubs have been present in all four; one patient showed pleural uptake of gallium-67. Extensive workups including repeated pulmonary ventilation-perfusion scans and cardiac catheterisation have not yielded other diagnoses to explain the pain. It is proposed that persistent pleuritic pain be added to the manifestations of benign asbestos induced pleural disease. Images PMID:2328221

Systemic and local inflammations have been described as relevant prognostic factors in patients with cancer. However, parameters that stand for immune activity in the pleural space have not been tested as predictors of survival in patients with malignant pleural effusion. The objective of this study was to evaluate pleural lymphocytes and Adenosine Deaminase (ADA) as predictors of survival in patients with recurrent malignant pleural effusion. Retrospective cohort study includes patients who underwent pleurodesis for malignant pleural effusion in a tertiary center. Pleural fluid protein concentration, lactate dehydrogenase, glucose, oncotic cytology, cell count, and ADA were collected before pleurodesis and analyzed. Survival analysis was performed considering pleurodesis as time origin, and death as the event. Backwards stepwise Cox regression was used to find predictors of survival. 156 patients (out of 196 potentially eligible) were included in this study. Most were female (72 %) and breast cancer was the most common underlying malignancy (53 %). Pleural fluid ADA level was stratified as low (<15 U/L), normal (15 ≤ ADA < 40), and high (≥40). Low and high ADA levels were associated with worse survival when compared to normal ADA (logrank: 0.0024). In multivariable analysis, abnormal ADA (<15 or ADA ≥ 40) and underlying malignancies different from lymphoma, lung, or breast cancer were associated with worse survival. Pleural fluid cell count and lymphocytes number and percentage did not correlate with survival. Pleural fluid Adenosine Deaminase levels (<15 or ≥40 U/L) and neoplasms other than lung, breast, or lymphoma are independent predictors of worse survival in patients with malignant pleural effusion who undergo pleurodesis.

Pleural effusions and diseases of the pleura.

PubMed

Noone, K E

1985-09-01

There are four factors that govern fluid movement to or from the pleural space: hydrostatic pressure, colloid osmotic pressure, filtration coefficient, and lymphatic function. When any of these factors are altered, fluid accumulates within the pleural space. Congestive heart failure, pancreatitis, neoplasia, hypoalbuminemia, and pulmonary thromboembolism can evoke pleural effusions by altering normal fluid transport mechanisms. This approach to pleural effusion helps to explain fluid accumulation. Chylothorax, hemothorax, and empyema are also covered in the article.

Limited data are available for the diagnostic value, and for the diagnostic sensitivity and specificity of joint detection of serum lactate dehydrogenase (sLDH)/pleural fluid adenosine deaminase (pADA) and pleural fluid carcinoembryonic antigen (pCEA) in malignant pleural effusion (MPE). We collected 987 pleural effusion specimens (of which 318 were malignant pleural effusion, 374 were tubercular pleural effusion, and 295 were parapneumonic effusion specimens) from the First Affiliated Hospital of Wenzhou Medical University from July 2012 to March 2016. The pADA, sLDH, pleural fluid LDH (pLDH), serum C-reactive protein (sCRP), pleural fluid protein, pCEA, white blood cell (WBC), and red blood cell (RBC) were analyzed, and the clinical data of each group were collected for statistical analysis. The level of sLDH/pADA, pCEA, and RBC from the MPE group was markedly higher than the tuberculosis pleural effusion (TB) group (Mann-Whitney U=28422.000, 9278.000, 30518, P=.000, .000, .000) and the parapneumonic pleural fluid group (Mann-Whitney U=5972.500, 7113.000, 36750.500, P=.000, .000, .000). The receiver operating characteristic curve ROC showed that the area under the ROC curve (AUC) (=0.924, 0.841) of pCEA and sLDH/pADA (cutoff=4.9, 10.6) were significantly higher than other markers for the diagnosis of MPE. Thus, joint detection of pCEA and sLDH/pADA suggested that the sensitivity, specificity, and AUC was 0.94, 81.70, and 94.32 at the cutoff 0.16 and diagnostic performance was higher than pCEA or sLDH/pADA. Joint detection of sLDH/pADA and pCEA can be used as a good indicator for the identification of benign and MPE with higher sensitivity and specificity than pCEA or sLDH/pADA. © 2016 Wiley Periodicals, Inc.

Jiang, Jinjun; Hu, Jie; Bai, Chunxue

2003-12-16

The role of the ENaC sodium channel and aquaporin-1 (AQP1) water channel on pleural fluid dynamics in mice was investigated. 0.25 ml of hypertonic or isosmolar fluid was infused into the pleural space in anesthetized wildtype and AQP1 null mice. Pleural fluid was sampled at specified times to quantify the osmolality and volume. The sodium channel activator terbutaline increased isosmolar fluid clearance by 90% while the sodium channel inhibitor amiloride decreased it by 15%, but had no effect on osmotically driven water transport. AQP1 deletion significantly decreased osmotic water transport in pleural space by twofold, but it had no effect on isosmolar fluid clearance. Pretreatment with dexamethasone increased pleural osmotic fluid entry by 25%, while intravenous injection of HgCl2 decreased osmotic pleural water movement by 43%. These results provided evidence for a role of a sodium channel in pleural fluid absorption; AQP1 plays a major role in osmotic liquid transport but it does not affect isosmolar fluid clearance.

The effect of changing the contact surface area between pleural liquid and pleura on the turnover of pleural liquid.

To study the dynamics of pleural liquid, 250 ml of saline labeled with markers were injected into the pleural cavity of anesthetized dogs. For 3 h, liquid volume and concentration of these markers were measured. In a control group of dogs, the turnover rate of pleural liquid was 19.6 +/- 5.6 ml/min and lymphatic flow was 0.58 +/- 0.07 ml/min. In a group of pneumonectomized dogs, the turnover rate and lymphatic flow fell to about one fourth of those in the control group. When the left pulmonary artery was occluded, the turnover rate was halved, but lymphatic flow was not significantly different from that in the control group. These results suggest that the turnover rate of pleural liquid is dependent on the area of contact between pleural liquid and pleura and on the blood flow of the pleura. In addition, it appears that changes in pleural liquid volume are dependent on lymphatic flow.

Immunosuppressed solid organ transplant recipients (SOTRs) have an increased risk of developing cutaneous squamous cell carcinomas (cSCCs) with metastatic potential. This study sought to determine the rate of regional lymph node involvement in a large cohort of solid organ transplant patients with cutaneous head and neck squamous cell carcinoma. A retrospective chart review was performed on solid organ transplant patients with head and neck cutaneous squamous cell carcinoma treated at a tertiary academic medical center from 2005 to 2015. 130 solid organ transplant patients underwent resection of 383 head and neck cutaneous squamous cell carcinomas. The average age of the patient was 63. Seven patients (5%) developed regional lymph node metastases (3 parotid, 4 cervical lymph nodes). The mean time from primary tumor resection to diagnosis of regional lymphatic disease was 6.7months. Six of these patients underwent definitive surgical resection followed by adjuvant radiation; one patient underwent definitive chemoradiation. 6 of the 7 patients died of disease progression with a mean survival of 15months. The average follow up time was 3years (minimum 6months). Solid organ transplant recipients with cutaneous squamous cell carcinoma of the head and neck develop regional lymph node metastasis at a rate of 5%. Regional lymph node metastasis in this population has a poor prognosis and requires aggressive management and surveillance. Copyright © 2017 Elsevier Inc. All rights reserved.

Objectives Maintenance therapy is a standard therapeutic strategy in non-squamous non-small-cell lung cancer. However, there is no consensus regarding the benefit of maintenance therapy for patients with squamous cell lung cancer. We assessed maintenance therapy with S-1, an oral fluoropyrimidine agent, following induction therapy with carboplatin and S-1 in patients with squamous cell lung cancer. Methods In this phase II trial, chemotherapy-naïve patients with squamous cell lung cancer were enrolled to induction therapy with four cycles of carboplatin (at an area under the curve of 5 on day 1) and S-1 (80 mg/m(2)/day on days 1-14) in a 28-day cycle. Patients who achieved disease control after induction therapy received maintenance therapy with S-1 in a 21-day cycle until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival after administration of maintenance therapy. Results Fifty-one patients were enrolled in the study. The median progression-free survival from the start of maintenance therapy was 3.0 months (95 % confidence interval, 2.5-3.5). The most common toxicities associated with maintenance therapy were anemia, thrombocytopenia, and fatigue, but they were not severe. Conclusion S-1 maintenance therapy might be a feasible treatment option in patients with squamous cell lung cancer.

Lung abscess predicts the surgical outcome in patients with pleural empyema

Objectives Most cases of pleural empyema are caused by pulmonary infections, which are usually combined with pneumonia or lung abscess. The mortality of patients with pleural empyema remains high (up to 20%). It also contributes to higher hospital costs and longer hospital stays. We studied pleural empyema with combined lung abscess to determine if abscess was associated with mortality. Methods From January 2004 to December 2006, we retrospectively reviewed 259 patients diagnosed with pleural empyema who received thoracscopic decortications of the pleura in a single medical center. We evaluated their clinical data and analyzed their chest computed tomography scans. Outcomes of pleural empyema were compared between groups with and without lung abscess. Results Twenty-two pleural empyema patients had lung abscesses. Clinical data showed significantly higher incidences in the lung abscess group of pre-operative leukocytosis, need for an intensive care unit stay and mortality. Conclusion Patients with pleural empyema and lung abscess have higher intensive care unit admission rate, higher mortality during 30 days and overall mortality than patients with pleural empyema. The odds ratio of lung abscess is 4.685. Physician shall pay more attention on high risk patient of lung abscess for early detection and management. PMID:20961413

Ultrasound has been shown to improve the accuracy and safety of pleural procedures. Studies to date have been performed in large, specialized units, where pleural procedures are performed by a small number of highly specialized physicians. There are no studies examining the safety and accuracy of ultrasound in the Australian healthcare system where procedures are performed by junior doctors with a high staff turnover. We performed a retrospective review of the ultrasound database in the Respiratory Department at the Royal Melbourne Hospital to determine accuracy and complications associated pleural procedures. A total of 357 ultrasounds were performed between October 2010 and June 2013. Accuracy of pleural procedures was 350 of 356 (98.3%). Aspiration of pleural fluid was successful in 121 of 126 (96%) of patients. Two (0.9%) patients required chest tube insertion for management of pneumothorax. There were no recorded pleural infections, haemorrhage or viscera puncture. Ward-based ultrasound for pleural procedures is safe and accurate when performed by appropriately trained and supported junior medical officers. Our findings support this model of pleural service care in the Australian healthcare system. © 2016 Asian Pacific Society of Respirology.

Expression of fibroblast specific protein-1 in pleural tuberculosis and its clinical biological significance

2014-01-01

Background Fibroblast specific protein-1 (S100A4) is related with many fibrotic diseases, but its role in the pathogenesis of pleural fibrosis has not been fully elucidated. Then we aim to investigate the expression and effect of fibroblast specific protein-1 (S100A4) in pleural tuberculosis and, subsequently, pleural fibrosis. Methods The expression of S100A4 in pleura was examined in 30 patients with pleural tuberculosis and 5 control (disease-free) patients by immunohistochemistry using the streptavidin-peroxidase (S-P) conjugated method. Results The expression of S100A4 in pleura was mainly distributed in the nucleus and cytoplasm of fibroblasts and vascular endothelial cells, and the positive rate was 90.0% (27 out of 30 patients with pleural tuberculosis). There were no expressions of S100A4 in the control group. In the pleura of all 30 patients with pleural tuberculosis, S100A4 had a higher expression in the two- to eight-week duration of the disease. Conclusions S100A4 plays an important role in the phenotypic transformation of pleural mesothelial cells and the development of pleural fibrosis. PMID:24885536

N-terminal pro-brain natriuretic peptide (NT-proBNP) is a biomarker useful in diagnosis of pleural effusion due to heart failure. Thus far, its overall diagnostic accuracy has not been systematically reviewed. The aim of the present meta-analysis was to establish the overall diagnostic accuracy of the measurement of pleural NT-proBNP for identifying pleural effusion due to heart failure. After a systematic review of English-language studies, sensitivity, specificity, and other measures of accuracy of NT-proBNP concentrations in pleural fluid in the diagnosis of pleural effusion resulting from heart failure were pooled using fixed-effects models. Summary receiver operating characteristic curves were used to summarise overall test performance. Eight publications met the inclusion criteria. The summary estimates for pleural NT-proBNP in the diagnosis of pleural effusion attributable to heart failure were: sensitivity 0.95 (95% CI 0.92 to 0.97), specificity 0.94 (0.92 to 0.96), positive likelihood ratio 14.12 (10.23 to 19.51), negative likelihood ratio 0.06 (0.04 to 0.09) and diagnostic OR 213.87 (122.50 to 373.40). NT-proBNP levels in pleural fluid showed a high diagnostic accuracy and may help accurately differentiate cardiac from non-cardiac conditions in patients presenting with pleural effusion.

In the course of various diseases, there is an accumulation of fluid in the pleural cavities. Pleural fluid accumulation causes thoracic volume expansion and reduction of volume lungs, leading to formation of restrictive disorders. The aim of the study was to estimate the volume of pleural fluid by ultrasonography and to search for the relationship between pleural fluid volume and spirometrical parameters. The study involved 46 patients (26 men, 20 women) aged 65.7 +/- 14 years with pleural effusions who underwent thoracentesis. Thoracentesis was preceded by ultrasonography of the pleura, spirometry test and plethysmography. The volume of the pleural fluid was calculated with the Goecke' and Schwerk' (GS) or Padykuła (P) equations. The obtained values were compared with the actual evacuated volume. The median volume of the removed pleural fluid was 950 ml. Both underestimated the evacuated volume (the median volume 539 ml for GS and 648 ml for P, respectively). Pleural fluid removal resulted in a statistically significant improvement in VC (increase 0.20 +/- 0.35 ; p < 0.05), FEV1 (increase 0.16 +/- 0.32 l; p < 0.05), TLC (increase 0.30 +/- 0.58 l; p < 0.05) and PEF (0.37 +/- 1 l/s; p < 0.05) CONCLUSIONS: Pleural fluid removal causes a significant improvement in lung function parameters. The analyzed equations for fluid volume calculation do not correlate with the actual volume.

When pleural procedures (thoracocentesis, blind pleural biopsies and chest tube insertion) are required in patients taking long-term platelet aggregation inhibitors, the risk of bleeding must be balanced against the risk of arterial thrombosis. Currently, the bleeding risk of pleural procedures is poorly understood. The objective of the survey was to gather the opinion of respiratory physicians regarding the bleeding risk of pleural procedures in patients taking platelet aggregation inhibitors. We emailed a standardized questionnaire designed by the French National Authority for Health to 2697 French respiratory physicians. One hundred and eighty-eight of the 2697 questionnaires were returned (response rate: 7 %). The respiratory physicians declared that they performed an average of 8 pleural procedures per month. One hundred and seventy-five responders (95 %) practised pleural procedures in patients receiving platelet aggregation inhibitors; 68 of them (39 %) reported experiencing haemorrhagic complications. The bleeding risk associated with thoracentesis and chest tube insertion was considered minor by 97.8 and 65 % of responders respectively, whereas it was considered major for blind pleural biopsies by 73.4 %. Respiratory physicians were more reticent about performing pleural procedures in patients treated with clopidogrel than in those taking aspirin. This study provides an overview of how respiratory physicians perceive the bleeding risk associated with pleural procedures in patients taking platelet aggregation inhibitors. Copyright © 2016 SPLF.

We investigated the clinical characteristics of pleural effusion in systemic lupus erythematosus (SLE). A prospective analysis of 17 SLE patients with pleural effusion (seven lupus pleuritis, eight transudative effusions and two parapneumonic effusions) was performed. Thirty non-SLE patients with pleural effusion were recruited as controls. A pleural fluid ANA titer ≥1:160 was found in 8/17 (47.1%) SLE patients and none of the 30 non-SLE patients (p = 0.0001). Pleural fluid to serum C3 ratios were significantly lower in SLE than in non-SLE (median (minimum-maximum) 0.29 (0.03-0.43) versus 0.52 (0.26-0.73), p = 0.0002). Among SLE patients, pleural fluid ANA titers ≥1:160 were more frequently found in patients with lupus pleuritis than in those with pleural effusion from causes other than lupus itself (85.7% versus 20.0%, p = 0.0152). Serum CRP levels were significantly increased in patients with lupus pleuritis compared with SLE patients with transudative pleural effusion (2.30 (0.30-5.66) versus 0.7 (0.12-1.47) mg/dl, p = 0.0062). In conclusion, pleural fluid ANA titer and serum CRP levels are significantly increased in lupus pleuritis. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Pleural abnormalities identified on anatomical studies are often nonspecific and may represent benign or malignant disease. We prospectively evaluated the ability of FDG-PET to identify malignancy in patients with pleural abnormalities detected on chest radiographs or chest CT. Thirty-two patients with pleural abnormalities (pleural masses, thickening or effusions) found on chest radiographs or CT were evaluated by FDG-PET. Regions of interest (ROI) were identified on the PET images correlating to anatomic abnormalities and standard uptake ratios (SUR`s) of these ROI`s were calculated. A SUR value of 2.5 or greater was considered positive for malignancy. Physicians blinded to biopsy results gradedmore » their confidence of malignancy (1-5 scale) and graded lesion FDG uptake with respect to mediastinal radioactivity. Twenty-three of the patients had definitive diagnoses by tissue biopsy. Seventeen of these patients had malignant (SUR=7.9{plus_minus}3.8) and 6 had benign (SUR=2.8{plus_minus}2.4) causes of their pleural abnormalities (p=0.001). All but two malignant cases had SURs higher than 2.5 and one of these two was correctly interpreted by the observers. SURs lower than 2.5 were seen in four of the six (67%) benign pleural abnormalities. Using a combination of both visual and semiquantitative analysis, the sensitivity of FDG-PET for detecting malignant pleural abnormalities was 94%. Active infections in the pleural space had increased FDG uptake on PET studies while other benign pleural abnormalities did not. FDG-PET has very high sensitivity for detecting malignant pleural abnormalities and can differentiate benign from malignant pleural abnormalities.« less

Plasma cell myeloma is a multifocal plasma cell neoplasm associated with increased monoclonal protein in serum and/or urine. Pleural effusions in patients with myeloma are uncommon (6 %). However, effusions due to direct infiltration of the pleura by plasma cells (myelomatous pleural effusion) are extremely rare (<1 %) and usually seen with IgA myeloma. The diagnosis of such cases requires pleural fluid cytology, electrophoresis or pleural biopsy. We present a case of myelomatous pleural effusion diagnosed using flow cytometry immunophenotyping in addition to the pleural fluid cytology. A 45 year old female was diagnosed as plasma cell myeloma (IgG kappa) in 2007. She received multiple lines of therapy during the course of her treatment including thalidomide, dexamethasone, lenalidomide, bortezomib, and doxorubicin based regimens. However, the patient had progressive extramedullary disease and developed pleural effusion in 2014. Cytological examination of the pleural fluid showed degenerative changes. Few preserved areas showed mononuclear cells including morphologically abnormal plasma cells. Immunophenotyping of these cells by flow cytometry revealed a pattern indicating neoplastic plasma cells. There was expression of CD38, CD138, and CD56, with absence of CD19, CD10 and CD45. This confirmed the diagnosis of myelomatous pleural effusion. Subsequently, the patient was offered a dexamethasone, cyclophosphamide, etoposide and cisplatin based regimen but, she declined further treatment and succumbed to her disease 3 months later. Myelomatous pleural effusion is a rare complication of plasma cell myeloma. Flow cytometry can be used as an adjunctive technique in its diagnosis particularly in cases with equivocal cytology and electrophoresis findings.

Pleural effusion: diagnosis, treatment, and management

A pleural effusion is an excessive accumulation of fluid in the pleural space. It can pose a diagnostic dilemma to the treating physician because it may be related to disorders of the lung or pleura, or to a systemic disorder. Patients most commonly present with dyspnea, initially on exertion, predominantly dry cough, and pleuritic chest pain. To treat pleural effusion appropriately, it is important to determine its etiology. However, the etiology of pleural effusion remains unclear in nearly 20% of cases. Thoracocentesis should be performed for new and unexplained pleural effusions. Laboratory testing helps to distinguish pleural fluid transudate from an exudate. The diagnostic evaluation of pleural effusion includes chemical and microbiological studies, as well as cytological analysis, which can provide further information about the etiology of the disease process. Immunohistochemistry provides increased diagnostic accuracy. Transudative effusions are usually managed by treating the underlying medical disorder. However, a large, refractory pleural effusion, whether a transudate or exudate, must be drained to provide symptomatic relief. Management of exudative effusion depends on the underlying etiology of the effusion. Malignant effusions are usually drained to palliate symptoms and may require pleurodesis to prevent recurrence. Pleural biopsy is recommended for evaluation and exclusion of various etiologies, such as tuberculosis or malignant disease. Percutaneous closed pleural biopsy is easiest to perform, the least expensive, with minimal complications, and should be used routinely. Empyemas need to be treated with appropriate antibiotics and intercostal drainage. Surgery may be needed in selected cases where drainage procedure fails to produce improvement or to restore lung function and for closure of bronchopleural fistula. PMID:27147861

Background Pulmonary embolism (PE) is a common and life-threatening condition associated with considerable morbidity and mortality. Pleural effusion occurs in about one in three cases; however, data on its prognostic value are scarce. Purpose To investigate the association between pleural effusion and both 30-day and long-term mortality in patients with acute PE. Material and Methods We retrospectively evaluated 463 patients diagnosed with acute PE using computed tomography pulmonary angiography (CTPA). Echocardiographic, demographic, and laboratory data were collected. The study population was divided into two groups: patients with and without pleural effusions. Pleural effusion detected on CT was graded as small, moderate, and large according to the amount of effusion. The predictors of 30-day and long-term total mortality were analyzed. Results Pleural effusions were found in 120 patients (25.9%). After the 30-day follow-up, all-cause mortality was higher in acute PE patients with pleural effusions than in those without (23% versus 9%, P < 0.001). Also, patients with pleural effusions had significantly higher incidence of long-term total mortality than those without pleural effusions (55% versus 23%, P < 0.001). In a multivariate analysis, pleural effusion was an independent predictor of 30-day and long-term mortality (odds ratio [OR], 2.154; 95% confidence interval [CI], 1.186-3.913; P = 0.012 and OR, 1.591; 95% CI, 1.129-2.243; P = 0.008, respectively). Conclusion Pleural effusion can be independently associated with both 30-day and long-term mortality in patients with acute PE.

Abstract Introduction: The diagnosis of pleural tuberculosis requires an invasive and time-consuming reference method. Polymerase chain reaction (PCR) is rapid, but validation in pleural tuberculosis is still weak. Objective: To establish the operating characteristics of real-time polymerase chain reaction (RT-PCR) hybridization probes for the diagnosis of pleural tuberculosis. Methods: The validity of the RT-PCR hybridization probes was evaluated compared to a composite reference method by a cross-sectional study at the Hospital Universitario de la Samaritana. 40 adults with lymphocytic pleural effusion were included. Pleural tuberculosis was confirmed (in 9 patients) if the patient had at least one of three tests using the positive reference method: Ziehl-Neelsen or Mycobacterium tuberculosis culture in fluid or pleural tissue, or pleural biopsy with granulomas. Pleural tuberculosis was ruled out (in 31 patients) if all three tests were negative. The operating characteristics of the RT-PCR, using the Mid-P Exact Test, were determined using the OpenEpi 2.3 Software (2009). Results: The RT-PCR hybridization probes showed a sensitivity of 66.7% (95% CI: 33.2%-90.7%) and a specificity of 93.5% (95% CI: 80.3%-98.9%). The PPV was 75.0% (95% CI: 38.8%-95.6%) and a NPV of 90.6% (95% CI: 76.6%-97.6%). Two false positives were found for the test, one with pleural mesothelioma and the other with chronic pleuritis with mesothelial hyperplasia. Conclusions: The RT-PCR hybridization probes had good specificity and acceptable sensitivity, but a negative value cannot rule out pleural tuberculosis. PMID:29021638

Percutaneous drainage of infected intraabdominal fluid collections is preferred over surgical drainage due to lower morbidity and costs. However, it can be a challenging procedure and catheter insertion carries the potential to contaminate the pleural space from the abdomen. This retrospective analysis demonstrates the clinical and radiographic correlation between percutaneous drainage of infected intraabdominal collections and the development of iatrogenic pleural space infections. A retrospective single institution analysis of 550 consecutive percutaneous drainage procedures for intraabdominal fluid collections was performed over 24 months. Patient charts and imaging were reviewed with regard to pleural space infections that were attributed to percutaneous drain placements. Institutional review board approval was obtained for conduct of the study. 6/550 (1.1%) patients developed iatrogenic pleural space infections after percutaneous drainage of intraabdominal fluid collections. All 6 patients presented with respiratory symptoms and required pleural space drainage (either by needle aspiration or chest tube placement), 2 received intrapleural fibrinolytic therapy and 1 patient had to undergo surgical drainage. Pleural effusion cultures revealed same bacteria in both intraabdominal and pleural fluid in 3 (50%) cases. A video with a dynamic radiographic sequence demonstrating the contamination of the pleural space from percutaneous drainage of an infected intraabdominal collection is included. Iatrogenic pleural space infections after percutaneous drainage of intraabdominal fluid collections occur at a low incidence, but the pleural empyema can be progressive requiring prompt chest tube drainage, intrapleural fibrinolytic therapy or even surgery. Expertise in intraabdominal drain placements, awareness and early recognition of this complication is critical to minimize incidence, morbidity and mortality in these patients.

Primary renal squamous cell carcinoma is a very rare malignancy of the upper urinary tract. Most patients have history of chronic urolithiasis, analgesics abuse, radiotherapy or infection. Co-existence of SCC with xanthogranulomatous pyelonephritis is exceedingly rare with only few reports in the literature. We report a case of a 60-year-old male presented with right flank pain and mild tenderness of abdomen. Computed tomography of the abdomen revealed gross hydronephrosis with parenchymal thinning and irregular thick enhancing wall of pelvicalyceal system with multiple calculi in right kidney. Right renal vein appeared distended, filled with hypo dense material. Right nephrectomy was performed and sent for pathological examination. Histological evaluation revealed keratinizing squamous cell carcinoma with infiltration of renal vein and xanthogranulomatous pyelonephritis. PMID:26816904

The coexistence of different types of malignancy in cervical lymph nodes has been reported previously. We report the first case, to the best of our knowledge, of concurrent metastatic adenoid cystic carcinoma and squamous cell carcinoma (SCC) in cervical lymph nodes. A primary SCC developed three decades after treatment for adenoid cystic carcinoma of the palate, and the synchronous metastases became clinically apparent the following year. The aetiology of the SCC may have been related to radiotherapy or smoking. Whether the adenoid cystic carcinoma would have remained dormant, or was reactivated after perturbation of host defence mechanisms, is not known.

Cancer cells exhibit characteristic damage of DNA and its expression. The expression of the tumor suppressors E-cadherin and p27(Kip1) has been tested on 57 head and neck squamous cell carcinomas (HNSCC) of Indonesian subjects. HNSCC tumor samples including both primary and (unrelated) nodal cases were obtained from the archives of Indonesian hospitals, in accordance with acknowledged ethical requirements. Only modest correlation was found between reduced expression of E-cadherin or p27(Kip1) with increased malignancy of primary and nodal growth. The observed strong correlation regardless of malignancy between the expressed levels of E-cadherin and p27(Kip1) suggests that also in combination these would not help to better predict the outcome of HNSCC.

Urinothorax refers to the presence of urine in the pleural space. Urinothorax is an infrequent and underdiagnosed pathology, with few cases reported, and these often suspected only with hindsight. It is usually a transudative pleural effusion. We report a case of urinothorax presenting as a purulent pleural effusion. Management of the urinothorax required antibiotics and surgical unblocking of the urinary tract. Currently, no test is available to confirm the diagnosis. The ratio of serum creatinine/pleural creatinine could suggest the presence of urinothorax but this parameter needs to be validated by complementary studies. Urinothorax should be suspected in the context of pleural effusion occurring after a recent urologic surgery. Copyright © 2018 SPLF. Published by Elsevier Masson SAS. All rights reserved.

Although during the last few years there have been several important changes in the diagnostic or therapeutic methods, pleural effusion is still one of the diseases that the respiratory specialist have to evaluate frequently. The aim of this paper is to update the knowledge about pleural effusions, rather than to review the causes of pleural diseases exhaustively. These recommendations have a longer extension for the subjects with a direct clinical usefulness, but a slight update of other pleural diseases has been also included. Among the main scientific advantages are included the thoracic ultrasonography, the intrapleural fibrinolytics, the pleurodesis agents, or the new pleural drainages techniques.

A 74-year-old man underwent right upper lobectomy for the lung cancer and bullectomy of right lower lobe. Fibrin sealant was used for sealing the excision line. The increase of the pleural effusion with increasing C-reactive protein( CRP) and eosinophilia was noted at the 17th day after the operation. The pleural effusion was transparent and yellowish colored suggesting transudatory liquid. The eosinophil in the pleural effusion was as high as 14%. The drainage of the pleural effusion was performed for 2 days resulting in disappearing the abnormal accumulation without any additional treatment. The cause of pleural effusion was supposed to be fibrin sealant by a positive result of the drug lymphocyte stimulation test.

Primary squamous cell carcinoma (SCC) of the thyroid gland is extremely rare. Infrequently, primary SCC of the thyroid gland is accompanied by other thyroid diseases such as Hashimoto's thyroiditis (HT). Recently, studies have demonstrated that differentiated thyroid cancer with coexisting HT has a better prognosis. However, the prognosis of patients with primary SCC of the thyroid gland and coexistent HT has not been clearly identified. We compared the clinical characteristics and disease stages of patients with primary SCC with and without lymphocytic thyroiditis (LT). We reviewed reports of primary SCC of the thyroid gland published in the English literature. We identified 46 papers that included 17 cases of primary SCC of the thyroid gland with LT and 77 cases of primary SCC of the thyroid gland without LT. Lymph node metastasis and local invasion rates did not differ between these two groups. Distant metastases were absent in patients with LT, and were observed in 13 (16.9%) patients without LT. A greater proportion of patients without LT had advanced stage disease (stage IV A-B-C) than patients with LT (p < 0.05). Patients with primary SCC of the thyroid gland and coexisting LT had lower tumour-node-metastasis stage and frequency of distant metastasis than those without LT. Lymphocytic infiltration in patients with SCC appears to limit tumour growth and distant metastases.

Several causes of eosinophilic pleural effusions have been described with malignancy being the commonest cause. Hypereosinophilic syndrome (HES) is a rare disease and very few cases have been reported of HES presenting as eosinophilic pleural effusion (EPE). We report a case of a 26-year-old male who presented with shortness of breath. He had bilateral pleural effusions, generalized lymphadenopathy, splenomegaly, and leukocytosis with marked peripheral blood eosinophilia. The pleural fluid was exudative, with 25%–30% eosinophilis, and absence of neoplastic cells. Hypereosinophilic syndrome was diagnosed after other causes of eosinophilia were excluded. He continued to be dyspneic with persistent accumulation of eosinophilic pleural fluid, even after his peripheral eosinophil count had normalized in response to treatment. This patient represents a very unusual presentation of HES with dyspnea and pleural effusions and demonstrates that treatment based on response of peripheral eosinophil counts, as is currently recommended, may not always be clinically adequate.

Ultrasonography of the thorax has become a more recognized tool in pulmonary medicine, thanks to continuing clinical research that has proven its many valuable roles in the day-to-day management of pulmonary and pleural diseases. Ultrasound examination is a cost-effective imaging modality that permits the pulmonologist to obtain information about the pathologies in the thorax without the risk of exposure to ionizing radiation, providing the examiner with real-time and immediate results. Its ease of use and training along with its portability to the patient's bedside and accurate examination of the pleural space has allowed for safer pleural procedures such as thoracentesis, chest tube placement, tunneled pleural catheter placement, and medical thoracoscopy. In this review, we summarize the technique of chest ultrasonography, compare ultrasound to other frequently used thoracic imaging modalities, and focus on its use in obtaining pleural access while performing invasive pleural procedures.

Endemic malignant pleural mesothelioma (MPM) in Turkey is related to two mineral fibers, tremolite asbestos and fibrous zeolite (erionite). Thirteen cases of MPM from the Cappadocian area, where the soil is rich in erionite, and 29 cases of MPM, from villages whose occupants have high asbestos exposure, were examined by CT. The CT findings of the two groups of MPM were compared with respect to the configuration of the pleural lesions, stage of disease, fissural involvement, pleural effusion, presence of calcified pleural plaques, and chronic fibrosing pleuritis. In erionite-related MPM the pleural lesions were flat and smooth in 69.1%; inmore » asbestos-related MPM the lesions were nodular in 55.1%. Stage IV disease, calcified pleural plaques, and chronic fibrosing pleuritis were more common in the erionite-related MPM. The rest of the findings were similar in both groups. The early radiological diagnosis of erionite-related MPM may be even more difficult because of the similarity of the pleural lesions to chronic fibrosing pleuritis.« less

The pleural curtain of the camel (Camelus dromedarius).

The visceral pleura of the camel (Camelus dromedarius) possesses a fibrous curtain of pleural threads or extensions along its basal margins, which extends into the pleural cavity of the costophrenic recesses. These threads are lined by mesothelium and have a core or stroma, which is largely collagenous. Small threads are avascular and nearly acellular. In larger proximal threads, blood vessels in the stroma are often arranged in a branching network, with irregular endothelia surrounded by several incomplete basal laminae. Lymphocytes and other inflammatory cell types aggregate in the stroma near blood vessels. The threads are lined by typical mesothelium except in patches close to the main pleural surface. These patches consist of layers of loosely applied cells with numerous cellular processes and features suggestive of phagocytosis. The position of the pleural curtain in the costophrenic recess and the presence of possibly phagocytotic cells suggest that the pleural curtain stirs, samples, and cleans the pleural fluid. The pleural curtain appears to be a feature of camelids and has also been seen in giraffes. Copyright © 2010 Wiley-Liss, Inc.

A 49-year-old male who had been treated for pulmonary tuberculosis and tuberculous pleurisy in 2007 was referred to our hospital with the complaint of dyspnea on exertion in Nov. 2009. Chest X-ray showed increased pleural effusion compared with that remaining after the previous treatment of pleurisy in 2008. A chest CT revealed that fluid collection was surrounded by thickened pleura. Thoracocentesis was performed, and yellow milky liquid was obtained. The pleural effusion contained few cells. The triglyceride concentration was 83 mg/dl, and the cholesterol level was very high at 628 mg/dl. Based on these findings we diagnosed this case as chyliform pleural effusion. Both smear of acid-fast bacilli and PCR-TB test of the pleural effusion were positive, but culture was negative for mycobacterium, suggesting that this chyliform pleural effusion was produced by the former episode of tuberculous pleurisy, not by the recent reactivation of tuberculous pleurisy. The ADA concentration in the pleural effusion was high at 91.7 IU/l. No increase in the amount of pleural effusion was observed after thoracocentesis without any anti-tuberculosis therapy.

Abstract On August 5, 2016, the U.S. Food and Drug Administration granted accelerated approval to pembrolizumab (KEYTRUDA injection, Merck Sharp & Dohme Corp., Kenilworth, NJ) for treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) with disease progression on or after platinum‐containing chemotherapy. Approval was based on the objective response rate (ORR) and duration of response (DoR) in a cohort of patients in a nonrandomized multi‐cohort trial (KEYNOTE‐012) that included 174 patients with recurrent or metastatic HNSCC who had disease progression on or after platinum‐containing chemotherapy. Patients received either intravenous pembrolizumab 10 mg/kg every 2 weeks or 200 mg every 3 weeks. ORR was determined by independent review according to Response Evaluation Criteria in Solid Tumors 1.1. ORR was 16% (95% confidence interval 11, 22) with a complete response rate of 5%. DoR ranged from 2.4+ months to 27.7+ months. Twenty‐three of 28 responding patients (82%) had response durations of ≥6 months. Safety was evaluated in 192 patients with HNSCC receiving at least one dose of pembrolizumab. Frequent (≥2%) serious adverse reactions were pneumonia, dyspnea, confusional state, vomiting, pleural effusion, and respiratory failure. Clinically significant immune‐mediated adverse reactions included pneumonitis, colitis, hepatitis, adrenal insufficiency, diabetes mellitus, skin toxicity, myositis, and thyroid disorders. The benefit‐risk profile of pembrolizumab was considered acceptable in this patient population. As a condition of accelerated approval, Merck is required to conduct a confirmatory trial; this trial, KEYNOTE‐040, is ongoing. Implications for Practice. This accelerated approval expands the U.S. Food and Drug Administration‐approved indications for pembrolizumab, providing health care providers with new information regarding pembrolizumab for the treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) with disease progression on or after platinum‐containing chemotherapy. Pembrolizumab is the first drug to receive approval for treatment of patients with HNSCC since cetuximab was approved for this indication in 2006. PMID:28533473

Endoscopic ultrasound-guided transesophageal thoracentesis for minimal pleural effusion.

Pleural effusion is a common finding both in patients with benign and malignant diseases of pleura and lung with diagnostic thoracentesis establishing the diagnosis in the majority of cases. The diagnostic thoracentesis can be done either blindly or under the guidance of ultrasound or computed tomography. However, minimal pleural effusion is difficult to sample even under image guidance. Endoscopic ultrasound (EUS) is known to detect smaller volume of pleural effusion and, thus, can help in guiding thoracentesis. To analyze the safety and efficacy of EUS-guided diagnostic thoracentesis in patients with undiagnosed minimal pleural effusion retrospectively. Retrospective analysis of the data of patients with minimal pleural effusion, who underwent EUS-guided transesophageal diagnostic thoracentesis over last 2 years, was performed. Thirteen patients (11 male; mean age 46.7 ± 16.2 years) with undiagnosed minimal pleural effusion underwent successful EUS-guided transesophageal diagnostic thoracentesis using a 22-G needle. Seven (53%) patients had fever on presentation whereas two presented with cough and loss of appetite. Eight to 54 mL fluid was aspirated with an attempt to completely empty the pleural cavity. There were no complications of the procedure. EUS-guided diagnostic thoracentesis is a safe and effective alternative for evaluating patients with minimal pleural effusion.

Pleural effusion is a common occurrence in patients with late-stage chronic kidney disease (CKD). In developing countries, many effusions remain undiagnosed after pleural fluid analysis (PFA) and patients are empirically treated with antitubercular therapy. The aim of this study was to evaluate the role of adenosine deaminase (ADA), nucleic acid amplification tests (NAAT) and medical thoracoscopy in distinguishing tubercular and non-tubercular aetiologies in exudative pleural effusions complicating CKD. Consecutive stage 4 and 5 CKD patients with pleural effusions underwent PFA including ADA and PCR [65 kDa gene; multiplex (IS6110, protein antigen b, MPB64)]. Patients with exudative pleural effusion undiagnosed after PFA underwent medical thoracoscopy. All 107 patients underwent thoracocentesis with 45 and 62 patients diagnosed as transudative and exudative pleural effusions, respectively. Twenty six of the 62 patients underwent medical thoracoscopy. Tuberculous pleurisy was diagnosed in six while uraemic pleuritis was diagnosed in 20 subjects. The sensitivity and specificity of pleural fluid ADA, 65 kDa gene PCR, and multiplex PCR were 66.7 and 90 per cent, 100 and 50 per cent, and 100 and 100 per cent, respectively. Thoracoscopy was associated with five complications in three patients. Uraemia remains the most common cause of pleural effusion in CKD even in high TB prevalence country. Multiplex PCR and thoracoscopy are useful investigations in the diagnostic work-up of pleural effusions complicating CKD while the sensitivity and/or specificity of ADA and 65 kDa gene PCR is poor.

In countries where tuberculosis is endemic, the main differential diagnosis for pleural infection by common bacteria is pleural tuberculosis. The purpose of our study was to determine the differences between pleural infection by common bacteria and that caused by pleural tuberculosis. Our study was a retrospective analysis and compared the characteristics of confirmed pleural infection by common bacteria (PIB) and that due to pleural tuberculosis (PT). For the PIB, the signs evolved for 2.4 ± 1.4 weeks versus 5.6 ± 2.2 weeks for the PT (P=0.01). In multivariate analysis, for PIB the onset of symptoms was more abrupt (OR=3.8 [1.5; 9.9]; P=0.01), asthenia was less frequent (OR=0.3 [0.1; 0.9]; P=0.03), pleural liquid was more purulent (OR=40.0 [15.0; 106.7]; P<0.01). The blood neutrophil count was more frequently raised in cases of PIB (OR=2.5 [1.2; 5.4]; P=0.02). Pneumothorax/hydropneumothorax was less frequent in PIB (OR=0.3 [0.1; 1.0]; P=0.04). Clinical differences exist between pleural effusions caused by tuberculosis (TB) and those due to other bacterial infections. However, they are not sufficiently sensitive and therefore the search for the tuberculous bacillus must be systematic while waiting for implementation of new diagnostic tests for the organism.

Our objective was to evaluate the efficacy of a standardised work-up in the diagnosis of pleural tuberculosis (TB) that included fibreoptic bronchoscopy and medical thoracoscopy. A consecutive series of 52 pleural TB patients observed during the period 2001–2015 was evaluated retrospectively. 20 females, mean (range) age 39.7 (18–74) years, and 32 males, mean (range) age 45.75 (21–83) years, were included (28 non-EU citizens (53.8%)). The diagnosis of TB infections was established by identification (using stains, culture or molecular tests) of Mycobacterium tuberculosis in the pleura, sputum and/or bronchial specimens, or by evidence of caseous granulomas on pleural biopsies. Patients with and without lung lesions were considered separately. The diagnostic yield of the microbiological tests on pleural fluid was 17.3% (nine out of 52 patients). Among the 18 patients with lung lesions, bronchial samples (washing, lavage or biopsy) were positive in 50% of cases (nine patients). Cultures of pleural biopsies were positive in 63% of cases (29 out of 46 patients); pleural histology was relevant in all patients. Without pleural biopsy, a diagnosis would have been reached in 15 out of 52 patients (28.6%) and in four of them only following culture at 30–40 days. An integrated diagnostic work-up that includes all the diagnostic methods of interventional pulmonology is required for a diagnosis of pleural TB. In the majority of patients, a diagnosis can be reached only with pleural biopsy. PMID:29318136

Purpose of review Pleural effusions have a major impact on the cardiorespiratory system. This article reviews the pathophysiological effects of pleural effusions and pleural drainage, their relationship with breathlessness, and highlights key knowledge gaps. Recent findings The basis for breathlessness in pleural effusions and relief following thoracentesis is not well understood. Many existing studies on the pathophysiology of breathlessness in pleural effusions are limited by small sample sizes, heterogeneous design and a lack of direct measurements of respiratory muscle function. Gas exchange worsens with pleural effusions and improves after thoracentesis. Improvements in ventilatory capacity and lung volumes following pleural drainage are small, and correlate poorly with the volume of fluid drained and the severity of breathlessness. Rather than lung compression, expansion of the chest wall, including displacement of the diaphragm, appears to be the principle mechanism by which the effusion is accommodated. Deflation of the thoracic cage and restoration of diaphragmatic function after thoracentesis may improve diaphragm effectiveness and efficiency, and this may be an important mechanism by which breathlessness improves. Effusions do not usually lead to major hemodynamic changes, but large effusions may cause cardiac tamponade and ventricular diastolic collapse. Patients with effusions can have impaired exercise capacity and poor sleep quality and efficiency. Summary Pleural effusions are associated with abnormalities in gas exchange, respiratory mechanics, respiratory muscle function and hemodynamics, but the association between these abnormalities and breathlessness remains unclear. Prospective studies should aim to identify the key mechanisms of effusion-related breathlessness and predictors of improvement following pleural drainage. PMID:25978627

To assess the association between CT features and EGFR, ALK, KRAS mutations in non-small cell lung cancer. Patients undergoing chest CT and testing for the above gene mutations were included. Qualitative evaluation of CTs included: lobe; lesion diameter; shape; margins; ground-glass opacity; density; cavitation; air bronchogram; pleural thickening; intratumoral necrosis; nodules in tumour lobe; nodules in non-tumour lobes; pleural retraction; location; calcifications; emphysema; fibrosis; pleural contact; pleural effusion. Statistical analysis was performed to assess association of features with each gene mutation. ROC curves for gene mutations were drawn; the corresponding area under the curve was calculated. P-values <0.05 were considered significant. Of 285 patients, 60/280 (21.43 %) were positive for EGFR mutation; 31/270 (11.48 %) for ALK rearrangement; 64/240 (26.67 %) for KRAS mutation. EGFR mutation was associated with air bronchogram, pleural retraction, females, non-smokers, small lesion size, and absence of fibrosis. ALK rearrangements were associated with age and pleural effusion. KRAS mutation was associated with round shape, nodules in non-tumour lobes, and smoking. This study disclosed associations between CT features and alterations of EGFR (air bronchogram, pleural retraction, small lesion size, absence of fibrosis), ALK (pleural effusion) and KRAS (round lesion shape, nodules in non-tumour lobes). Air bronchogram, pleural retraction, small size relate to EGFR mutation in NSCLC. Pleural effusion and younger age relate to ALK mutation. Round lesion shape, nodules in non-tumour lobes relate to KRAS mutation.

To evaluate the feasibility and efficacy of pneumothorax creation and chest tube insertion before computed tomography (CT)-guided coil localization of small peripheral lung nodules for video-assisted thoracoscopic surgical (VATS) wedge resection. From May 2011 to October 2013, 21 consecutive patients (seven men; mean age, 62 y; range, 42-76 y) scheduled for VATS wedge resection required CT-guided coil localization for small, likely nonpalpable peripheral lung lesions at a single institution. Outcomes were evaluated retrospectively for technical success and complications. There were 12 nodules and nine ground-glass opacities. Mean lesion distance from the pleural surface was 15 mm (range, 5-35 mm), and average size was 13 mm (range, 7-30 mm). A pneumothorax was successfully created in all patients with a Veress needle, and a chest tube was inserted. All target lesions were marked successfully, leaving one end of the coil within/beyond the lesion and the other end of the coil in the pleural space. The inserted chest tube was used to insufflate air to widen the pleural space during coil positioning and to aspirate any residual air before transfer of the patient to the operating room holding area. Intraparenchymal hemorrhages smaller than 7 cm in diameter developed in two patients during coil placement. All lesions were successfully resected with VATS. Histologic examinaiton revealed 13 primary adenocarcinomas, four metastases, and four benign lesions. Pneumothorax creation and chest tube placement before CT-guided coil localization of peripheral lung nodules for VATS wedge resection facilitates the deployment of the peripheral end of the coil in the pleural space and provides effective management of procedure-related pneumothorax until surgery.

Obtaining qualitative data directly from the patient perspective enhances the content validity of patient-reported outcome (PRO) instruments. The objective of this qualitative study was to evaluate the content validity of the Lung Cancer Symptom Scale for Mesothelioma (LCSS-Meso) and its usability on an electronic device. A cross-sectional methodological study, using a qualitative approach, was conducted among patients recruited from four clinical sites. The primary target population included patients with pleural mesothelioma; data were also collected from patients with peritoneal mesothelioma on an exploratory basis. Semi-structured interviews were conducted consisting of concept elicitation, cognitive interviewing, and evaluation of electronic patient-reported outcome (ePRO) usability. Participants (n = 21) were interviewed in person (n = 9) or by telephone (n = 12); 71% were male with a mean age of 69 years (SD = 14). The most common signs and symptoms experienced by participants with pleural mesothelioma (n = 18) were shortness of breath, fluid build-up, pain, fatigue, coughing, and appetite loss. The most commonly described symptoms for those with peritoneal mesothelioma (n = 4) were bloating, changes in appetite, fatigue, fluid build-up, shortness of breath, and pain. Participants with pleural mesothelioma commonly described symptoms assessed by the LCSS-Meso in language consistent with the questionnaire and a majority understood and easily completed each of the items. The ePRO version was easy to use, and there was no evidence that the electronic formatting changed the way participants responded to the questions. Results support the content validity of the LCSS-Meso and the usability of the electronic format for use in assessing symptoms among patients with pleural mesothelioma.

Translating the recent success of chimeric antigen receptor (CAR) T cell therapy for hematological malignancies to solid tumors will necessitate overcoming several obstacles, including inefficient T cell tumor infiltration and insufficient functional persistence. Taking advantage of an orthotopic model that faithfully mimics human pleural malignancy, we evaluated two routes of administration of mesothelin-targeted T cells using the M28z CAR. We found that intra-pleurally administered CAR T cells vastly out-performed systemically infused T cells, requiring 30-fold fewer M28z T cells to induce long-term complete remissions. Following intrapleural T cell administration, prompt in vivo antigen-induced T cell activation allowed robust CAR T cell expansion and effector differentiation, resulting in enhanced anti-tumor efficacy and functional T cell persistence for 200 days. Regional T cell administration also promoted efficient elimination of extrathoracic tumor sites. This therapeutic efficacy was dependent on early CD4+ T cell activation associated with a higher intra-tumoral CD4/CD8 cell ratios and CD28-dependent CD4+ T cell-mediated cytotoxicity. In contrast, intravenously delivered CAR T cells, even when accumulated at equivalent numbers in the pleural tumor, did not achieve comparable activation, tumor eradication or persistence. The remarkable ability of intrapleurally administered T cells to circulate and persist supports the concept of delivering optimal CAR T cell therapy through “regional distribution centers.” Based on these results, we are opening a phase I clinical trial to evaluate the safety of intrapleural administration of mesothelin-targeted CAR T cells in patients with primary or secondary pleural malignancies.

Pleural effusion is a common clinical manifestation with various causes. Current diagnostic and therapeutic methods have exhibited numerous limitations. By involving the analysis of dynamic changes in low molecular weight catabolites, metabolomics has been widely applied in various types of disease and have provided platforms to distinguish many novel biomarkers. However, to the best of our knowledge, there are few studies regarding the metabolic profiling for pleural effusion. In the current study, 58 pleural effusion samples were collected, among which 20 were malignant pleural effusions, 20 were tuberculous pleural effusions and 18 were transudative pleural effusions. The small molecule metabolite spectrums were obtained by adopting 1H nuclear magnetic resonance technology, and pattern-recognition multi-variable statistical analysis was used to screen out different metabolites. One-way analysis of variance, and Student-Newman-Keuls and the Kruskal-Wallis test were adopted for statistical analysis. Over 400 metabolites were identified in the untargeted metabolomic analysis and 26 metabolites were identified as significantly different among tuberculous, malignant and transudative pleural effusions. These metabolites were predominantly involved in the metabolic pathways of amino acids metabolism, glycometabolism and lipid metabolism. Statistical analysis revealed that eight metabolites contributed to the distinction between the three groups: Tuberculous, malignant and transudative pleural effusion. In the current study, the feasibility of identifying small molecule biochemical profiles in different types of pleural effusion were investigated reveal novel biological insights into the underlying mechanisms. The results provide specific insights into the biology of tubercular, malignant and transudative pleural effusion and may offer novel strategies for the diagnosis and therapy of associated diseases, including tuberculosis, advanced lung cancer and congestive heart failure.

VATS and open chest surgery in diagnosis and treatment of benign pleural diseases

PubMed Central

Rathinam, Sridhar; Waller, David A.

A negative pressure normally exists between the visceral and parietal pleurae in the lungs, which can act as vacuum for fluid, air and small particles from different parts of the body, allowing them to move into the pleural space and be retained in it, thus resulting to different manifestations of pleural disorders. A pleural effusion is the result of fluid collection between the parietal and visceral pleural surfaces. The most common cause in developed countries is congestive heart failure, followed by pneumonia and malignancy. It is highly important that a systematic approach is undertaken during the investigation of pleural effusions. Treatment should be based on the nature of the effusion and underlying condition, while undiagnosed patients should remain under surveillance. Pleural infection is a serious clinical condition which affects approximately 65,000 patients every year in the UK and can result in mortality in rates as high as 20%. The selection of treatment as well as timing of intervention remains a debatable issue among pulmonologists and thoracic surgeons. Surgical intervention aims to control sepsis, by facilitating evacuation of necrotic material from the pleural space, and obliterate the empyema cavity, by allowing the trapped lung to re-expand via peeling of the organised cortex from its visceral pleura. Thoracoscopic surgery offers the advantages of visual assessment of the pleural space and direct tissue sampling and it can be useful for the diagnosis of unknown pleural effusions and in the management of complicated collections. Open thoracotomy remains the gold standard, however with the advancement of thoracoscopic instruments and techniques, minimally invasive approaches provide comparable outcomes and have been taking over the management of benign pleural diseases.

Patients with cancer are at an increased risk of tuberculosis. As pleural effusion has great clinical significance in patients with cancer, the differential diagnosis between tuberculous pleural effusion (TPE) and malignant pleural effusion (MPE) is important. However, the predictive factors and treatment outcomes of TPE in patients with cancer have rarely been studied. Confirmed TPE cases identified at cancer diagnosis and during anticancer management from 2008-2015 were retrospectively investigated. Patients in the study included coexisting TPE and cancer (n = 20), MPE (n = 40) and TPE without cancer (n = 40). Control groups were patients with MPE, and patients with TPE without cancer. Clinical, laboratory and pleural fluid characteristics were compared among groups. Treatment outcomes were compared between patients with TPE with and without cancer. In the final analysis, serum C-reactive protein (S-CRP) ≥3.0mg/dL and pleural fluid adenosine deaminase (ADA) ≥40U/L were independent predictors for identifying TPE in patients with cancer having pleural effusion. The combination of S-CRP with pleural fluid ADA using an "or" rule achieved a sensitivity of 100%, whereas both parameters combined in an "and" rule had a specificity of 98%. Treatment outcomes were not different between the TPE groups with and without cancer. S-CRP and pleural fluid ADA levels may be helpful for predicting TPE in patients with cancer with pleural effusion. The combination of these biomarkers provides better information for distinguishing between TPE and MPE in these patients. Treatment outcomes of TPE in patients with cancer are comparable to those in patients without cancer. Copyright © 2017 Southern Society for Clinical Investigation. Published by Elsevier Inc.

Postoperative pleural effusions are common in patients who undergo cardiac surgery and orthotopic heart transplant. Postoperative pleural effusions may also occur as postcardiac injury syndrome. Most of these effusions are nonspecific and develop as a harmless complication of the surgical procedure itself and generally have a benign course. Here, we investigated the cause and clinical and laboratory features of postoperative early and late pleural effusions in orthotopic heart transplant patients. We retrospectively reviewed the medical records of 50 patients who underwent orthotopic heart transplant between 2004 and 2015 at Baskent University. Patient demographics and clinical and laboratory data, including cause of heart failure, presence of pleural effusions at chest radiography in the first year after transplant, timing of onset, microbiologic and biochemical analyses of pleural effusions, and treatment strategies were noted. Mean age of patients was 39.22 ± 13.83 years (39 men, 11 women). Reason for heart failure was dilated cardiomyopathy in most patients (76%). Nineteen patients (38%) had postoperative pleural effusions, with 15 patients (78.9%) with pleural effusion during the first week after transplant. Of these, 4 patients had recurrent pleural effusion. A diagnostic thoracentesis was performed in 10 patients, with 4 showing transudative effusion and 6 showing exudative effusion secondary to infection (2 patients), postcardiac injury syndrome (1 patient), and hemothorax (3 patients). Aspergillus fumigatus was detected by quantitative culture from pleural effusion in 1 patient. Tube thoracoscopy drainage was performed in 10 patients (25%), and 2 patients received antibiotic therapy. Pleural effusions are frequent after cardiac transplant. Complications may occur in a small portion of patients, with most effusions being nonspecific and having a benign course with spontaneous resolution. Early diagnostic thoracentesis could improve postoperative outcomes in these patients.

Preoperative evaluation of patients with suspected or confirmed lung cancer consists of clinical and radiological staging. Malignant pleural effusion is a poor prognosticator in non-small-cell lung cancer. Pleural ultrasound (PU) allows for the assessment of pleural effusion, providing real-time guidance for its aspiration and cytological analysis. Pleural Ultrasonography in Lung Cancer (PULC) as an adjunct to physical examination has the potential to improve preoperative staging of non-small-cell lung cancer during first surgical encounter by allowing the evaluation of previously unassessed pleural effusion. This study consisted of a prospective trial of surgeon-performed PU in the preoperative evaluation of lung cancer patients. All patients evaluated in the thoracic surgery clinic with the new or presumed diagnosis of lung cancer were eligible. A portable ultrasound machine was used to evaluate pleural fluid in the bilateral costophrenic sulci with pleural fluid aspiration for cytological analysis. Forty-five patients were prospectively enrolled over a 3-month period. Thirteen patients had ultrasound evidence of a pleural effusion, of which 3 were significant enough for aspiration. Cytological analysis of these effusions yielded malignant cells in 1 patient. Positive PULC evaluation led to a change in clinical staging (M0 to M1a) in 10 patients and a change in pathological staging (pleural fluid cytology positive) in 1 patient. The time required for PULC examination was 15 ± 7 min. There were no complications related to the procedures. Preoperative pleural ultrasonography is a rapid and effective way to improve precision of staging in patients with lung cancer. More precise staging may allow for more appropriate testing, patient prognostication and operative planning.

Clinical laboratories are expected to reliably identify human papilloma virus (HPV) associated oropharyngeal squamous cell carcinoma (OPSCC) for prognostic and potential therapeutic applications. In addition to surrogate p16 immunohistochemistry (IHC) testing, DNA-based HPV-specific testing strategies are widely utilized. Recognizing the efficiency of the Roche Cobas 4800 platform for testing gynecological cytology specimens for high-risk HPV, we elected to evaluate the potential utility of this platform for testing formalin-fixed paraffin-embedded (FFPE) OPSCC tissue. Using the Roche Linear Array assay for comparison, we tested twenty-eight samples (16 primary OPSCC, 2 lymph node metastases from primary OPSCC, 1 oral tongue carcinoma, 3 benign squamous papillomas, and 3 non-oropharyngeal carcinoma tissues). Excluding two invalid results, the Roche Cobas 4800 testing resulted in excellent inter-assay concordance (25/26, 96.2%) and 100% concordance for HPV-16/HPV-18 positive samples. This data suggests that the Roche Cobas 4800 platform may be a cost-effective method for testing OPSCC FFPE tissues in a clinical molecular pathology laboratory setting.

STUDY PURPOSES: To survey hospital laboratories in the United States to determine methods used for measuring pleural fluid pH, and to compare pleural fluid pH values obtained with a traditional tabletop blood gas analyzer (BGA) to those obtained with a handheld analyzer. Hospital laboratories nationwide were contacted by telephone to survey the methods used to measure pleural fluid pH. In a second phase, pleural fluid was prospectively collected from 19 pediatric and adult patients with pleural effusions, and pleural fluid pH was measured simultaneously with a traditional tabletop BGA and with a handheld unit. A total of 220 hospital laboratories were contacted by telephone, and 166 responded (75%). The methods for determining pleural fluid pH for all hospital laboratories were pH meter (35%; n = 59), BGA (32%; n = 53), and litmus paper (31%: n = 51); 2% (n = 3) did not perform the test. University hospitals were more likely to use a BGA, compared to community hospitals (p < 0.014) or children's hospitals (p < 0.001). In the comparison of pleural fluid measurements, the mean pH for the traditional BGA was 7.358 +/- 0.189, and the mean pH for the handheld unit was 7.382 +/- 0.203. The absolute difference between the two machines was 0.024 U, and the two methods were correlated (p < 0.01; r = 0.993; degrees of freedom = 36). Most hospital laboratories in the United States do not measure pleural fluid pH using a traditional BGA and use alternative methods that have previously been shown to be inaccurate. Pleural fluid pH obtained by a handheld unit has a high degree of correlation to that of a traditional tabletop BGA, and it offers a satisfactory alternative for laboratories reluctant to measure pleural fluid pH with a BGA.

Exudative pleural effusions affect over 1500 patients per million population each year. The pathobiology of pleural exudate formation remains unclear. Our recent study revealed monocyte chemotactic protein-1 (MCP-1) as a key driver of fibrinolytic-induced exudate effusion while another study found a role for MCP-1 in malignant effusion formation. In the present study, we further evaluated the role of MCP-1 in the development of pleural effusion in a mouse model of acute pleural inflammation. λ-Carrageenan (CAR) was injected into the pleural cavity of CD1 mice and pleural effusion volume measured up to 16 h post-injection. Pleural effusion and serum protein and MCP-1 concentrations were measured and differential cell counts performed in fluids. Mice were also treated with either intraperitoneal (i) anti-MCP-1 antibody or isotype control or (ii) an MCP-1 receptor (CCR2) antagonist or vehicle control 12 h prior to and at the time of CAR injection. Intrapleural CAR induced significant pleural fluid accumulation (300.0 ± 49.9 μL) in mice after 4 h. Pleural fluid MCP-1 concentrations were significantly higher than corresponding serum MCP-1 (144 603 ± 23 204 pg/mL vs 3703 ± 801 pg/mL, P < 0.0001). A significant decrease in pleural fluid formation was seen both with anti-MCP-1 antibody (median (interquartile range, IQR): 36 (0-168) μL vs controls 290 (70-436) μL; P = 0.02) or CCR2 antagonist (153 (30-222) μL vs controls 240 (151-331) μL, P = 0.0049). Blockade of MCP-1 activity significantly reduced inflammatory pleural effusion formation in a CAR model. Together with recent successes in MCP-1 blockade in other effusion formation models, our data strongly support clinical evaluation of MCP-1 antagonists as a novel approach to pleural fluid management. © 2016 Asian Pacific Society of Respirology.

Pleural effusion is a common clinical problem that can complicate many medical conditions. Breathlessness is the most common symptom of pleural effusion of any cause and the most common reason for pleural drainage. However, improvement in breathlessness following drainage of an effusion is variable; some patients experience either no benefit or a worsening of their breathlessness. The physiological mechanisms underlying breathlessness in patients with a pleural effusion are unclear and likely to be multifactorial with patient-related and effusion-related factors contributing. A comprehensive study of the physiological and symptom responses to drainage of pleural effusions may provide a clearer understanding of these mechanisms, and may identify predictors of benefit from drainage. The ability to identify those patients whose breathlessness will (or will not) improve after pleural fluid drainage can help avoid unnecessary pleural drainage procedures, their associated morbidities and costs. The PLeural Effusion And Symptom Evaluation (PLEASE) study is a prospective study to comprehensively evaluate factors contributing to pleural effusion-related breathlessness. The PLEASE study is a single-centre prospective study of 150 patients with symptomatic pleural effusions that require therapeutic drainage. The study aims to identify key factors that underlie breathlessness in patients with pleural effusions and develop predictors of improvement in breathlessness following effusion drainage. Participants will undergo evaluation pre-effusion and post-effusion drainage to assess their level of breathlessness at rest and during exercise, respiratory and other physiological responses as well as respiratory muscle mechanics. Pre-drainage and post-drainage parameters will be collected and compared to identify the key factors and mechanisms that correlate with improvement in breathlessness. Approved by the Sir Charles Gairdner Group Human Research Ethics Committee (HREC number 2014-079). Registered with the Australian New Zealand Clinical Trials Registry (ACTRN12616000820404).

2015-05-01

The therapy of spontaneous pneumothorax is a common necessity in hospitals of all care hierarchies In addition to sufficient primary treatment by placement of a thorax drainage, knowledge of complicationg constellations, recognition of complications and irregular courses during the therapy of spontaneous pneumothorax are of fundamental importance for achieving a satisfactory treatment outcome. Furthermore, the enlightenment of patients regarding the pathogenesis of the disease, possible measures for influencing the recurrence rate and information about future behavioral and lifestyle modifications are important. The principal complications during hospital treatment can be subdivided into complications of the surgical placement of the thorax drain and relief of the pleural cavity, problems in the management of treatment of the pleural negative pressure, the possibly demanding management of a persisting air leak and the individualized decision-making with respect to an interventional or operative procedure. The most common complicating constellations and possible complications during the inpatient hospital stay are described, the.

An 81-year-old man was admitted with bilateral pleural effusion. A clinical examination showed lymphocytic pleura effusion and elevated serum IgG4 levels, so that IgG4-related disease was suggested, whereas tuberculous pleurisy was suspected because of high adenosine deaminase (ADA) levels in the pleural effusion. A surgical pleural biopsy revealed that there were large numbers of IgG4-positive cells and IgG4/IgG positive cell ratio exceeded 40% in several sites. Accordingly, we diagnosed IgG4-related pleuritis and treated with the patient with glucocorticoid therapy. The ADA levels in pleural effusion can increase in IgG4-related pleuritis, and it is therefore important to perform a pleural biopsy.

Systemic lupus erythematosus with initial presentation of empyematous pleural effusion in an elderly male patient: a diagnostic challenge.

Systemic lupus erythematosus (SLE) poses great difficulty in making an early diagnosis in elderly males, often presenting with atypical manifestations. Acute onset of empyematous pleural effusion has rarely been seen. Herein, we report a 66-year-old man with SLE presenting with rapid progression of bilateral pleural effusion. Diagnostic thoracocentesis disclosed neutrophil-predominant exudates and chest computed tomography revealed multiple loculated pleural effusions. Nevertheless, optimal antibiotic therapy plus surgical decortication of the pleura did not improve his condition. The diagnosis of SLE was readily established after LE cells were accidentally found in the pleural effusion. Large amounts of pleural effusion subsided soon after high dose corticosteroid therapy.

Lymphatic filariasis is a tropical parasitic disease and is endemic in India. It is present in various forms but its manifestation as pleural effusion is rare. Here, we describe a case of 58-year-old male who presented with complaint of left side chest pain and breathlessness. He was investigated and diagnosed as a case of left side pleural effusion due to filariasis, with peripheral blood lymphocytosis but without peripheral blood or pleural fluid eosinophilia. Our case foregrounds that filariasis can present with peripheral blood lymphocytosis and without peripheral blood or pleural fluid eosinophilia. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Round atelectasis (shrinking pleuritis) is typically a localized process characterized by focal pleural scarring and subjacent peripheral atelectasis. We report three patients, studied at autopsy, with an unusual variant of round atelectasis, termed shrinking pleuritis with lobar atelectasis, which is characterized by lobar atelectasis, visceral pleural fibrosis involving multiple lobes, interlobar fibrous cords, pleural effusion, and nonspecific, persistent infiltrates on chest radiogram. The possible causes of shrinking pleuritis with lobar atelectasis in our patients were multiple and included environmental dust exposure, infection, uremia, and recurrent pleural effusions. Our findings support both the folding (pleural effusion) and fibrosing (pleural injury) theoriesmore » of pathogenesis of round atelectasis and emphasize the spectrum of morphologic variability in this condition.« less

Conventional therapy for cervical node squamous cell carcinoma metastases from an unknown primary can cause considerable toxicity owing to the volume of tissues to be irradiated. In the present study, hypothesizing that using intensity-modulated radiotherapy (IMRT) would provide effective treatment with minimal toxicity, we reviewed the outcomes and patterns of failure for head-and-neck unknown primary cancer at a single tertiary cancer center. We retrospectively reviewed the records of 52 patients who had undergone IMRT for an unknown primary at M.D. Anderson Cancer Center between 1998 and 2005. The patient and treatment characteristics were extracted and the survival rates calculated using the Kaplan-Meier method. Of the 52 patients, 5 presented with Stage N1, 11 with Stage N2a, 23 with Stage N2b, 6 with Stage N2c, 4 with Stage N3, and 3 with Stage Nx disease. A total of 26 patients had undergone neck dissection, 13 before and 13 after IMRT; 14 patients had undergone excisional biopsy and presented for IMRT without evidence of disease. Finally, 14 patients had received systemic chemotherapy. All patients underwent IMRT to targets on both sides of the neck and pharyngeal axis. The median follow-up time for the surviving patients was 3.7 years. The 5-year actuarial rate of primary mucosal tumor control and regional control was 98% and 94%, respectively. Only 3 patients developed distant metastasis with locoregional control. The 5-year actuarial disease-free and overall survival rate was 88% and 89%, respectively. The most severe toxicity was Grade 3 dysphagia/esophageal stricture, experienced by 2 patients. The results of our study have shown that IMRT can produce excellent outcomes for patients who present with cervical node squamous cell carcinoma metastases from an unknown head-and-neck primary tumor. Severe late complications were uncommon. Copyright © 2010 Elsevier Inc. All rights reserved.

Studies on older patients undergoing primary Fontan operation (FO) are limited, with conflicting results. We review our experience with these patients beyond the first decade of life. Between January 2000 and December 2014, a total of 105 patients ≥10 years of age (mean 15.6 ± 4.9, range 10-31, median 15 years) underwent primary FO without a prior bidirectional superior cavopulmonary anastomosis (Bidirectional Glenn [BDG]). Mean preoperative New York Heart Association (NYHA) class was 2.2 ± 0.57. Operative procedure was extra-cardiac FO in 62 patients (8 were fenestrated). Forty-three had a lateral tunnel FO (26 were fenestrated). There were 11 (10.5%) early deaths. Fourteen of the 94 early survivors experienced prolonged pleural effusions, 7 had arrhythmias, and 2 had thromboembolic events. Two patients underwent Fontan takedown. On univariate analysis, NYHA functional class III, mean pulmonary artery (PA) pressure ≥15 mm Hg, hematocrit ≥60%, preoperative ventricular dysfunction, and atrioventricular valve regurgitation (AVVR) were associated with early mortality. Median follow-up was 78 (mean 88.9 ± 6.3) months. In 94 survivors, 6 (6.4%) late deaths were encountered. At last follow-up, 81 (86.2%) survivors were in NYHA class I. Actuarial survival was 84.7% ± 3.7% at 5, 10, and 15 years. Carefully selected adolescents and young adults can safely undergo the primary FO. However, persistent pleural effusions, arrhythmias, thromboembolic events, and the need for reoperation mandate regular follow-up in such patients. Preoperative NYHA functional class III, mean PA pressure ≧ 15 mm Hg, hematocrit ≥ 60%, ventricular dysfunction, and AVVR were associated with early mortality, suggesting that primary FO should be avoided in such patients.

Introduction: Primary squamous cell carcinoma (SCC) of the thyroid gland is one of the rarest types of all reported thyroid malignancies worldwide. It is very aggressive in nature and carries a poor prognosis. The surgical resection with adjuvant radiotherapy and chemotherapy is the most recommended treatment despite its poor reported outcome. Case Report: A 74-year-old woman presented with a rapidly progressive neck swelling, with hoarseness and compressive symptoms. Physical examination revealed a multilobulated firm thyroid mass with unilateral vocal cord palsy. Histopathological findings confirmed the diagnosis of SCC while radiological investigations and panendoscopy findings ruled out the possibility of other primary tumors. A surgical intervention was performed; however, the patient eventually succumbed to death prior to undergoing an oncological treatment. Conclusion: With no standard consensus to guide the management plan, SCC of the thyroid gland presents a great challenge for the managing team to come up with the best treatment option, due to its unfavorable rate of survival.

Abstract Our study sought to determine whether the size of the residual apical pleural space in young patients with primary spontaneous pneumothorax (PSP) following video-assisted thoracoscopic surgery is associated with the risk of recurrence. We retrospectively reviewed patients (≤30 years’ old) with primary spontaneous pneumothorax following thoracoscopic surgery (2002–2010) in a university-affiliated hospital. The size of residual apical pleural space was estimated by measuring the apex-to-cupola distance on a postoperative chest radiograph at 2 time windows: first between postoperative day (POD) 0 and 3, and second between POD 4 and 14. A total of 149 patients were enrolled with a median follow-up of 11.2 months (interquartile range, 0.95–29.5 months), of whom 141 (94.6%) were male with a mean age of 20 years. The postoperative recurrence rate was 11.4%. Comparing the characteristics between the patients with and without recurrent pneumothorax, the patients with recurrence were younger (18.2 + 2.4 vs 20.7 + 3.7 years, P = 0.008), with a lower rate of pleurodesis (35% vs1 69%, P = 0.037), longer apex-to-cupola distance at POD 0 to 3 (22.41 ± 19.56 vs 10.07 ± 10.83 mm, P < 0.001) and POD 4 to 14 (11.82 ± 9.75 vs 5.54 ± 8.38 mm, P = 0.005) than the patients without recurrence. In a multivariate logistic regression model for recurrent pneumothorax, age <18 years (P = 0.026, odds ratio [OR]: 4.694), apex-to-cupola distance at POD 0 to 3 >10 mm (P = 0.027, OR: 5.319), and no pleurodesis during VATS (P = 0.022, OR: 5.042) were independent risk factors for recurrent pneumothorax. The recurrence rate was not low (11.4%) in young patients with PSP following VATS. Residual apical pleural space with apex-to-cupola distance of 10 mm or greater at POD 0 to 3, younger age, and no pleurodesis would increase postoperative recurrence of primary spontaneous pneumothorax.

Pleural effusion is a potential complication following blunt splenic injury. The incidence, risk factors, and clinical management are not well described in children. Ten-year retrospective review (January 2000-December 2010) of an institutional pediatric trauma registry identified 318 children with blunt splenic injury. Of 274 evaluable nonoperatively managed pediatric blunt splenic injures, 12 patients (4.4%) developed left-sided pleural effusions. Seven (58%) of 12 patients required left-sided tube thoracostomy for worsening pleural effusion and respiratory insufficiency. Median time from injury to diagnosis of pleural effusion was 1.5days. Median time from diagnosis to tube thoracostomy was 2days. Median length of stay was 4days for those without and 7.5days for those with pleural effusions (p<0.001) and 6 and 8days for those pleural effusions managed medically or with tube thoracostomy (p=0.006), respectively. In multivariate analysis, high-grade splenic injury (IV-V) (OR 16.5, p=0.001) was associated with higher odds of developing a pleural effusion compared to low-grade splenic injury (I-III). Pleural effusion following pediatric blunt splenic injury has an incidence of 4.4% and is associated with high-grade splenic injuries and longer lengths of stay. While some symptomatic patients may be successfully managed medically, many require tube thoracostomy for progressive respiratory symptoms. Copyright © 2014 Elsevier Inc. All rights reserved.

Transdiaphragmatic transport of tracer albumin from peritoneal to pleural liquid measured in rats.

PubMed

Lai-Fook, Stephen J; Houtz, Pamela K; Jones, Philip D

2005-12-01

In conscious Wistar-Kyoto rats, we studied the uptake of radioactive tracer (125)I-albumin into the pleural space and circulation after intraperitoneal (IP) injections with 1 or 5 ml of Ringer solution (3 g/dl albumin). Postmortem, we sampled pleural liquid, peritoneal liquid, and blood plasma 2-48 h after IP injection and measured their radioactivity and protein concentration. Tracer concentration was greater in pleural liquid than in plasma approximately 3 h after injection with both IP injection volumes. This behavior indicated transport of tracer through the diaphragm into the pleural space. A dynamic analysis of the tracer uptake with 5-ml IP injections showed that at least 50% of the total pleural flow was via the diaphragm. A similar estimate was derived from an analysis of total protein concentrations. Both estimates were based on restricted pleural capillary filtration and unrestricted transdiaphragmatic transport. The 5-ml IP injections did not change plasma protein concentration but increased pleural and peritoneal protein concentrations from control values by 22 and 30%, respectively. These changes were consistent with a small (approximately 8%) increase in capillary filtration and a small (approximately 20%) reduction in transdiaphragmatic flow from control values, consistent with the small (3%) decrease in hydration measured in diaphragm muscle. Thus the pleural uptake of tracer via the diaphragm with the IP injections occurred by the near-normal transport of liquid and protein.

Lung cancer has a predilection to widely metastasize to the liver, bone, brain and adrenal glands. Metastasis of primary lung tumors to the stomach is infrequent, with only sporadic cases reported. Most cases are asymptomatic and diagnosed post-mortem on autopsy. The incidence of symptomatic gastrointestinal metastases is extremely rare. Herein, we describe a case of gastric metastasis by squamous cell lung carcinoma, presenting as melena and diagnosed by esophagogastroduodenoscopy. To the best of our knowledge, only twenty other cases in the English literature have reported symptomatic gastric metastasis of lung cancer diagnosed by endoscopic biopsy. A brief review of the literature shows gastric metastasis of lung cancer to have a predilection to occur most frequently in male smokers with the most common type of tumor likely to be squamous cell carcinoma.

Metastatic disease to the stomach or duodenum is an infrequent diagnosis, and head and neck squamous cell carcinoma (HNSCC) is one of the least common primary malignancies that lead to gastric or duodenal metastases. We report the case of a 65-year-old man with human immunodeficiency virus infection and previously diagnosed HNSCC who presented with melena. The patient had a percutaneous endoscopic gastrostomy tube placed 3 months prior to his presentation. Laboratory testing was significant for normocytic anemia and a digital rectal examination was positive for melena. Esophagogastroduodenoscopy revealed numerous cratered nodules with contact bleeding in the stomach as well as the duodenum that appeared malignant. Biopsies of the gastric and duodenal nodules were positive for p40 and CK 5/6, consistent with metastatic squamous cell carcinoma.

Performance of the Xpert MTB/RIF for the detection of Mycobacterium tuberculosis in pleural liquid is poorly described. The aim of this study was to determine its usefulness for the etiological diagnosis of a tuberculous pleurisy. We performed a descriptive cross-sectional study, with analytical design, including all the patients having a unilateral serofibrinous pleurisy, exudative, lymphocytic, and sterile. The diagnosis of pleural tuberculosis was considered based on epidemiological, clinical, paraclinical and therapeutic arguments. The Xpert MTB/RIF of the pleural fluid was carried out among all patients. Pleural tuberculosis was confirmed in 301 patients. The median age was 32years. Our study has included 217 men (72.1%) with a final sex ratio of 2.6. The cost of the pleural biopsy coupled with histology made it practicable in only 90 patients (29.9%) with a yield of 80%. The Xpert MTB/RIF of the pleural liquid was positive in only 10 patients (3.3% of the cases). Gene amplification by Xpert MTB/RIF of the pleural liquid is much less effective in establishing the diagnosis of tuberculous pleurisy than pleural biopsy, which remains the gold standard.

Non-small cell lung cancer (NSCLC) is a common malignant disease, and in ~10-20% of patients, pleural effusion is the first symptom. The pleural effusion proteome contains information on pulmonary disease that directly or indirectly reflects pathophysiological status. However, the proteome of pleural effusion in NSCLC patients is not well understood, nor is the variability in protein composition between malignant and benign pleural effusions. Here, we investigated the different proteins in pleural effusions from NSCLC and tuberculosis (TB) patients by using nano-scale liquid chromatography-tandem mass spectrometry (nLC-MS/MS) analysis. In total, 363 proteins were identified in the NSCLC pleural effusion proteome with a low false discovery rate (<1%), and 199 proteins were unique to NSCLC. The proteins in the NSCLC patients' pleural effusion were involved in cell adhesion, proteolysis, and cell migration. Furthermore, interleukin 1 alpha (IL1A), a protein that regulates tumor growth, angiogenesis, and metastasis, was significantly more abundant in the NSCLC group compared to the TB group, a finding that was validated with an ELISA assay.

Estimation of the pleural effusion's volume is an important clinical issue. The existing methods cannot assess it accurately when there is large volume of liquid in the pleural cavity and/or the patient has some other disease (e.g. pneumonia). In order to help solve this issue, the objective of this study is to develop and test a novel algorithm using B-spline and local clustering level set method jointly, namely BLL. The BLL algorithm was applied to a dataset involving 27 pleural effusions detected on chest CT examination of 18 adult patients with the presence of free pleural effusion. Study results showed that average volumes of pleural effusion computed using the BLL algorithm and assessed manually by the physicians were 586 ml±339 ml and 604±352 ml, respectively. For the same patient, the volume of the pleural effusion, segmented semi-automatically, was 101.8% ±4.6% of that was segmented manually. Dice similarity was found to be 0.917±0.031. The study demonstrated feasibility of applying the new BLL algorithm to accurately measure the volume of pleural effusion.

Influence of the softness of the parietal pleura on respiratory sliding mechanisms

PubMed Central

Kim, Jae Hun; Butler, James P.; Loring, Stephen H.

2011-01-01

The pleural surfaces of the lung and chest wall slide against each other with low friction. Normal load support can be effected either by a combination of quasi-static fluid pressure and solid-solid contacts of relatively stiff asperities, or by shear-induced hydrodynamic pressures in the pleural fluid layer. To distinguish between these mechanisms, we measured surface topography and spatial distribution of stiffness of rat parietal pleura using atomic force microscopy. The topography of the pleural surface has unevenness at length scales smaller than the thickness of pleural fluid, similar to mesothelial cell diameters. The estimated maximum normal contact pressure that could be borne by asperities of the soft pleura is much less than that required to support a substantial difference between pleural fluid pressure and the pleural surface pressure. These results suggest that during sliding motion, unevenness of the pleural surface is smoothed by local hydrodynamic pressure, preventing any significant contribution of solid-solid contacts.

Pleural effusion, an accumulation of pleural fluid, contains proteins originated from plasma filtrate and, especially when tissues are damaged, parenchyma interstitial spaces of lungs and/or other organs. This study details protein profiles in human pleural effusion from 43 lung adenocarcinoma patients by a two-dimensional nano-high performance liquid chromatography electrospray ionization tandem mass spectrometry (2D nano-HPLC-ESI-MS/MS) system. The experimental results revealed the identification of 1415 unique proteins from human pleural effusion. Among these 124 proteins identified with higher confidence levels, some proteins have not been reported in plasma and may represent proteins specifically present in pleural effusion. These proteins are valuable for mass identification of differentially expressed proteins involved in proteomics database and screening biomarker to further study in human lung adenocarcinoma. The significance of the use of proteomics analysis of human pleural fluid for the search of new lung cancer marker proteins, and for their simultaneous display and analysis in patients suffering from lung disorders has been examined.

Conventional Abrams biopsy shows low sensitivity in suspected malignant pleural disease. There are limited data on the improvement in sensitivity by adding in image guidance. This retrospective study compares the diagnostic sensitivity of Abrams biopsy using ultrasound guidance with CT-guided Tru-Cut biopsy in suspected malignant pleural disease. Data were collected from 2006 to 2012 of patients who underwent image-guided biopsies for suspected non-tuberculous pleural disease. Data were collected on the result of the initial biopsy and final patient diagnosis as of June 2015. Sixty-three patients underwent image-guided Abrams biopsy and 29 underwent CT-guided Tru-Cut biopsies. The sensitivity of Abrams was 71.43 % compared to 75 % in the CT-guided Tru-Cut group. Specificity was 100 % in both groups. Image-guided Abrams biopsies demonstrate comparable diagnostic sensitivity in malignant pleural disease to CT-guided Tru-Cut biopsy.

The aim of this study was to clarify whether level IIb dissection should be performed or avoided in the treatment of oral squamous cell carcinoma by meta-analysis. Articles that were published before June 2017 were searched electronically in four databases (Web of Science, PubMed, Ovid and China National Knowledge Infrastructure) without any date or language restrictions by two independent reviewers. Abstracts and full-text papers which investigated the cervical metastases to level IIb from primary head and neck cancers and were deemed potentially relevant were screened. Data were analyzed using RevMan 5.3. Four hundred and fifty-five abstracts and 129 full-text papers were screened, and 22 studies were included in the analysis. Among the 2001 patients included, 112 patients had level IIb metastases, the pooled frequency of which was 6% (95% confidence interval [CI]: 4.0-7.0). Among the 400 patients with tongue squamous cell carcinoma from 12 studies, 37 patients had level IIb metastases, the pooled incidence of which was 7% (95% CI: 5.0-10.0). Metastases to level IIb always went together with level IIa, and only three patients were found to have isolated level IIb metastases without involving the other levels. Due to the low frequency of level IIb nodal metastases in oral squamous cell carcinoma patients and rare occurrence of isolated level IIb, level IIb dissection could be avoided when the primary lesions were in early stages (T1 and T2), with the exception of tongue cancer. It is recommended to dissect level IIb tongue cancers without considering the stages of primary lesions and the lymph nodes status. It is also suggested that level IIb dissection should be performed in patients preoperatively or intraoperatively found with multilevel neck metastasis, especially level IIa metastasis.

Erlotinib, an inhibitor of tyrosine kinase activity of the epidermal growth factor receptor, is effective in non-small cell lung cancer (NSCLC). Data on erlotinib use in squamous NSCLC are limited. This observational study aimed at evaluating the efficacy and safety of second-line erlotinib in patients with stage IIIB/IV squamous NSCLC in a real-life setting. Patients with predominantly squamous stage IIIB/IV NSCLC, who failed first-line platinum-based therapy, were recruited and followed-up for 12 months. Patients underwent visits each trimester. Data were derived from case report forms, and functional assessment of cancer therapy-lung (FACT-L) questionnaires. A total of 152 patients were enrolled; the majority were males (90%) and mean age was 67.7 years. All patients had squamous (97%) or predominantly squamous (3%) NSCLC, of stage IIIB (21%) or IV (79%). Median progression free survival (PFS) and overall survival were 3 and 5.8 months, respectively. Disease progression was observed in the majority of the patients, mostly due to progression of primary tumour and/or metastatic sites, and led to death in 91/107 of patients. Of the 107 deaths reported, none were due to erlotinib. FACT-L questionnaires were interpretable up to the first visit and were in line with PFS data, showing a relatively good quality of life up to Month 3 (mean total score=78.8). No new or unexpected safety issues were reported. The results of this real-life cohort study like those of previous phase III/IV subgroups study analyses indicate that erlotinib is a valuable option for second-line treatment of stage IIIB/IV squamous NSCLC.

In the current study the presence of extracellular IL-1B, IL-8, OAZ and SAT mRNAs in the saliva was evaluated as a tool in the early detection of oral squamous cell carcinoma. 34 patients with primary oral squamous cell carcinoma stage T1N0M0/T2N0M0, 20 patients with oral leukoplakia and dysplasia (15 patients with mild dysplasia and 5 with severe dysplasia/in situ carcinoma) and 31 matched healthy-control subjects were included in the study. The presence of IL-1B, IL-8, OAZ and SAT mRNA was evaluated in extracellular RNA isolated from saliva samples using sequence-specific primers and real-time RT-PCR. ROC curve analysis was used to estimate the ability of the biomarkers to detect oral squamous cell carcinoma patients. The data reveal that the combination of these four biomarkers provides a good predictive probability of up to 80% (AUC=0.799, p=0.002) for patients with oral squamous cell carcinoma but not patients suffering from oral leukoplakia with dysplasia. Moreover, the combination of only the two biomarkers (SAT and IL-8) also raises a high predictive ability of 75.5% (AUC=0.755, p=0.007) approximately equal to the four biomarkers suggesting the use of the two biomarkers only in the prediction model for oral squamous cell carcinoma patients limiting the economic and health cost in half. SAT and IL-8 mRNAs are present in the saliva in high quality and quantity, with a good discriminatory ability for oral squamous cell carcinoma patients only but not for patients with oral leukoplakia and dysplasia an oral potentially malignant disorder.

The functional aspects of programmed death 1 (PD-1) and PD ligand 1 (PD-L1) immune checkpoints in malignant mesothelioma have not been studied. Tumor samples from 65 patients with mesothelioma were evaluated for PD-L1 expression by immunohistochemistry, and its prognostic significance was examined. Malignant effusions from patients with pleural and peritoneal mesothelioma were evaluated for PD-1-positive and PD-L1-positive infiltrating lymphocytes and their role in inducing PD-L1 expression in tumor cells. Antibody-dependent cellular cytotoxicity (ADCC) of avelumab, a fully humanized immunoglobulin G1 anti PD-L1 antibody against primary mesothelioma cell lines, was evaluated in presence of autologous and allogeneic natural killer cells. Of 65 pleural and peritoneal mesothelioma tumors examined, 41 (63%) were PD-L1-positive, which was associated with slightly inferior overall survival compared to patients with PD-L1-negative tumors (median 23.0 versus 33.3 months, p = 0.35). The frequency of PD-L1 expression was similar in patients with pleural and peritoneal mesothelioma, with 62% and 64% of samples testing positive, respectively. In nine mesothelioma effusion samples evaluated, the fraction of cells expressing PD-L1 ranged from 12% to 83%. In seven patients with paired malignant effusion and peripheral blood mononuclear cell (PBMC) samples, PD-L1 expression was significantly higher on CD3-positive T cells present in malignant effusions as compared with PBMCs (p = 0.016). In addition, the numbers of CD14-positive PD-1-positive cells were increased in malignant effusions compared with PBMCs (p = 0.031). The lymphocytes present in malignant effusions recognized autologous tumor cells and induced interferon-γ-mediated PD-L1 expression on the tumor cell surface. Of the three primary mesothelioma cell lines tested, two were susceptible to avelumab-mediated ADCC in the presence of autologous natural killer cells. Most pleural as well as peritoneal mesotheliomas express PD-L1. Malignant effusions in this disease are characterized by the presence of tumor cells and CD3-positive T cells that highly express PD-L1. In addition, mesothelioma tumor cells are susceptible to ADCC by the anti-PD-L1 antibody avelumab. Published by Elsevier Inc.

INTRODUCTION The functional aspects of programmed death 1 (PD-1) and PD ligand 1 (PD-L1) immune checkpoints in malignant mesothelioma have not been studied. METHODS Tumor samples from 65 patients with mesothelioma were evaluated for PD-L1 expression by immunohistochemistry and its prognostic significance. Malignant effusions from patients with pleural and peritoneal mesothelioma were evaluated for PD-1+ and PD-L1+ infiltrating lymphocytes and their role in inducing tumor cell PD-L1 expression. Antibody dependent cellular cytotoxicity (ADCC) of avelumab, a fully humanized IgG1 anti PD-L1 antibody towards primary mesothelioma cell lines was evaluated in presence of autologous and allogeneic NK cells. RESULTS Of 65 pleural and peritoneal mesothelioma tumors examined, 41 (63%) were PD-L1 positive, which was associated with slightly inferior overall survival compared to patients with PD-L1 negative tumors (median 23.0 vs. 33.3 months; p=0.35). The frequency of PD-L1 expression was similar in pleural and peritoneal mesothelioma patients with 62% and 64% of samples positive, respectively. Of nine mesothelioma effusion samples evaluated, the fraction of cells expressing PD-L1 ranged from 12 to 83%. Of 7 patients with paired malignant effusion and peripheral blood mononuclear cells (PBMC) samples, PD-L1 expression was significantly higher on CD3+ T cells present in malignant effusions as compared with PBMC (p=0.016).

Vorinostat is a histone deacetylase inhibitor that changes gene expression and protein activity. On the basis of the clinical benefit reported in patients with malignant pleural mesothelioma treated in a phase 1 study of vorinostat, we designed this phase 3 trial to investigate whether vorinostat given as a second-line or third-line therapy improved patients' overall survival. This double-blind, randomised, placebo-controlled trial was done in 90 international centres. Patients with measurable advanced malignant pleural mesothelioma and disease progression after one or two previous systemic regimens were eligible. After stratification for Karnofsky performance status, histology, and number of previous chemotherapy regimens, patients were randomly assigned (1:1) by use of an interactive voice response system with a block size of four to either treatment with vorinostat or placebo. Patients received oral vorinostat 300 mg (or matching placebo) twice daily on days 1, 2, 3, 8, 9, 10, 15, 16, and 17 of a 21-day cycle. The primary endpoints were overall survival and safety and tolerability of vorinostat. The primary efficacy comparison was done in the intention-to-treat population, and safety and tolerability was assessed in the treated population. This trial is registered with ClinicalTrials.gov, number NCT00128102. From July 12, 2005, to Feb 14, 2011, 661 patients were enrolled and randomly assigned to receive either vorinostat (n=329) or placebo (n=332) and included in the intention-to-treat analysis. Median overall survival for vorinostat was 30·7 weeks (95% CI 26·7-36·1) versus 27·1 weeks (23·1-31·9) for placebo (hazard ratio 0·98, 95% CI 0·83-1·17, p=0·86). The most common grade 3 or worse adverse events for patients treated with vorinostat were fatigue or malaise (51 [16%] patients in the vorinostat group vs 25 [8%] in the placebo group]) and dyspnoea (35 [11%] vs 45 [14%]). In this randomised trial, vorinostat given as a second-line or third-line therapy did not improve overall survival and cannot be recommended as a therapy for patients with advanced malignant pleural mesothelioma.

1975-08-01

Twenty-three specimens of pleural fluid from 23 patients were examined for quantitative fibrinogen, total protein levels, and for clottability in vitro using the recalcification time. Of the 19 specimens of pleural fluid from patients without loculation, 11 (seven exudates) had no detectable fibrinogen; another 8 (six exudates) had a mean fibrinogen level of 55.0 +/- 10.2 mg percent, and a mean recalcification time of 19.4 +/- 2.6 minutes. The pleural fluids from the four patients with loculation had no detectable fibrinogen. The only fluids containing fibrinolytic activity were from the nonloculated non-fibrinogen-containing group. No correlation existed between pleural fluid/plasma total protein ratios and pleural fluid/plasma fibrinogen ratios. In vitro clottability in this study did not reflect the in vivo tendency for coagulation and loculation.

Pleural mesothelioma - case report.

Pleural mesothelioma is a very rare neoplasm; especially the local form. The diagnostics is difficult and the prognosis unfavourable. We presented a case of a man with dyspnoea and cough. His chest radiogram showed hydrothorax on the left side. Neither the examinations of the pleural liquid, nor the CT-guided fine needle biopsy established the diagnosis. CT showed features suggestive of pleural mesothelioma. The diagnosis was confirmed by thoracoscopy. Although no neoplastic cells were found in the thoracoscopic specimen from the supradiaphragmatic tumor, we assumed that to be a case of a diffuse, primarily local form of mesothelioma. Diagnostics of pleural mesothelioma is very difficult. CT and thoracoscopy seem to be very valuable diagnostic methods. It is worth remembering that pleural mesothelioma can have a local form which may transform into a diffuse one.

A 72-year-old man with chronic alcohol related pancreatitis was admitted for dyspnea and pain at the upper body. Chest X-ray showed right massive pleural effusion. Chest and abdominal contrast enhanced thin slice computed tomography revealed the route from the pancreatic head reaching the right thoracic cavity via the esophagus hiatus and the communication between the cystic lesion and main pancreatic duct. We drained the pleural effusion that showed abnormally high amylase activity. We diagnosed his illness as mediastinal pancreatic pseudocyst with pancreatic pleural effusion. Endoscopic Nasopancreatic Drainage catheter was placed in the main pancreatic duct, and the pleural effusion disappeared.

We present three cases of successful chemical pleurodesis with a liquid solution of mistletoe extract using a spray catheter during medical thoracoscopy. The medical thoracoscopy was performed in all presented cases to remove pleural effusion and conduct chemical pleurodesis to manage symptomatic malignant pleural effusion. A spray catheter was used to instil the mistletoe extract evenly into the pleural cavity, and there were no pleurodesis-related complications. Respiratory symptoms caused by pleural effusion improved after pleurodesis, and successful pleurodesis was maintained for more than 3 months after medical thoracoscopy in all three patients.

A retrospective analysis of 38 patients with primary squamous cell carcinoma of the vagina seen at Stanford University Medical Center from 1958 to 1984 was undertaken. Patients were analyzed with regard to symptoms, stage, treatment techniques, survival, patterns of failure, and complications. Eighteen patients were classified as FIGO Stage I, 5 as Stage II, 10 as Stage III, and 5 as Stage IV. The 5-year disease-free survival was 94% in Stage I, 80% in Stage II, 50% in Stage III, and 0% in Stage IV. Five patients (13%) had eight major complications secondary to treatment.

Forty-three cases of primary vaginal squamous cell cancer were treated at the University of Wisconsin Hospital between 1956 and 1971. These cases comprised of 1.2% of patients admitted to the University Hospital with female genital tract cancer. Evidence is presented to support a modification of the currently accepted FIGO staging system for vaginal carcinoma (Stage II disease). Radiation therapy using both external beam and brachyradium equivalents or interstitial implantation of suitable isotopes was an effective method for the treatment of patients having early and locally advanced invasive vaginal cancer. The 5-year absolute survival rate for the entire series was 37.2%.more » Absolute survival rate by modified FIGO clinical staging was 66% for Stages I and IIA, 31% for Stage IIB, 25% for Stage III, and 0% for Stage IV.« less

Purpose: This study was conducted to determine the expression of Bmi-1 and podoplanin in healthy oral mucosa and in untreated tumor tissues samples of patients with squamous cell carcinomas of the head and neck. All patients were treated by primary radio(chemo)therapy. Methods and Materials: The expression of Bmi-1 and podoplanin was immunohistochemically evaluated in 12 normal oral mucosa and 63 tumor specimens and correlated with patients' clinical data. Results: In healthy mucosa expression of Bmi-1 and podoplanin was restricted to the basal cell layer. Expression of both proteins was found in 79% and 86% of our tumor samples, respectively. Inmore » 17 and 8 samples, Bmi-1 and podoplanin were co-expressed at the invasive border or diffuse in the bulk of the tumor, respectively. Univariate analysis showed that the co-expression of Bmi-1 and podoplanin correlated to decreased overall survival (p = 0.044). Moreover, multivariate testing identified high expression of podoplanin (p = 0.044), co-expression of Bmi-1 and podoplanin (p = 0.007) and lack of response to therapy (p < 0.0001) as predictors of shortened overall survival in patients treated with primary radio(chemo)therapy. Conclusions: Bmi-1 and podoplanin are expressed at the invasive front of squamous cell carcinomas of the head and neck. Co-expression of Bmi-1 and podoplanin predicts significantly overall survival of patients treated with primary radio(chemo)therapy.« less

In lung cancer patients where a malignant pleural effusion is found at operation could resection ever still be justified?

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether surgery could ever be justified in non-small cell lung cancer patients with an unexpected malignant pleural effusion at surgery. Eight papers were chosen to answer the question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers were tabulated. Study limitations included a lack of retrospective studies, the heterogeneous patient population and various treatments applied. Three papers found that surgery--compared to exploratory thoracotomy--was associated with a survival advantage in cases of minimal pleural disease. One paper showed that the median survival time of 58.8 months in patients with pleural effusion was better than that of patients with more extensive pleural dissemination as pleural nodule (10 months; P=0.0001) or pleural nodule with effusion (19.3 months; P=0.019). Another study showed that pleural effusion patients with N0-1 status had a median survival time more than 5 years longer than patients with similar or more extensive pleural dissemination but with N2-N3 status. A further study showed a better 5-year survival time in patients with pleural effusion, than in patients with pleural nodule (22.9% vs 8.9%, respectively; P=0.45). In two papers, surgery vs exploratory thoracotomy had better survival in cases of N0 status and of complete tumour resection independently of pleural dissemination. Different strategies were employed to obtain freedom from macroscopic residual tumour, including pneumonectomy, lobar resection or, to a lesser extent, pleurectomy in patients having pleural dissemination. Only one paper reported a worse median survival time after pneumonectomy than for more limited resections (12.8 vs 24.1 months, respectively; P=0.0018). In the remaining papers, no comparison between the different resections was made. In all studies except one, surgery was a component of multimodal treatment. Intrapleural chemotherapy was largely applied with systemic adjuvant chemotherapy and/or radiotherapy. The study period and/or year of publication of most papers was 10 years or more, this may explain the different chemotherapy regimens used in the various studies. No current guidelines support surgery over conservative therapy and the identified studies in this review are not strong enough to change this recommendation.

Background Clinical applicability of folate receptor-targeted intraoperative molecular imaging (FR-IMI) has been established for surgically resectable pulmonary adenocarcinoma. A role for FR-IMI in other lung cancer histologies has not been studied. In this study, we evaluate feasibility of FR-IMI in patients undergoing pulmonary resection for squamous cell carcinomas (SCCs). Methods In a human clinical trial (NCT02602119), twelve subjects with pulmonary SCCs underwent FR-IMI with a near-infrared contrast agent that targets the folate receptor-α (FRα), OTL38. Near-infrared signal from tumors and benign lung was quantified to calculate tumor-to-background ratios (TBR). Folate receptor-alpha expression was characterized, and histopathologic correlative analyses were performed to evaluate patterns of OTL38 accumulation. An exploratory analysis was performed to determine patient and histopathologic variables that predict tumor fluorescence. Results 9 of 13 SCCs (in 9 of 12 of subjects) displayed intraoperative fluorescence upon NIR evaluation (median TBR, 3.9). OTL38 accumulated within SCCs in a FRα-dependent manner. FR-IMI was reliable in localizing nodules as small as 1.1 cm, and prevented conversion to thoracotomy for nodule localization in three subjects. Upon evaluation of patient and histopathologic variables, in situ fluorescence was associated with distance from the pleural surface, and was independent of alternative variables including tumor size and metabolic activity. Conclusions This work demonstrates that FR-IMI is potentially feasible in 70% of SCC patients, and that molecular imaging can improve localization during minimally invasive pulmonary resection. These findings complement previous data demonstrating that ∼98% of pulmonary adenocarcinomas are localized during FR-IMI and suggest broad applicability for NSCLC patients undergoing resection.

Nowadays the level of early and late complications after the operations for esophageal corrosive strictures such as esophago-organ anastomotic leak, development of infections, pneumonia, pleural empyema, mediastinitis, peritonitis, postoperative corrosive stricture development etc. remains rather high. Besides, postoperative mortality rate is high as well - 3.5-30 %. For that reason, an experimental model of esophageal stricture was suggested and ultrastructural mucosal changes in the stricture itself were studied to elaborate the unified pathogenic approach in treatment of esophageal stricture and improvement of its results. The aim of our work was to study the dynamics of ultrastructural changes both in normal esophageal walls and in third degree esophageal stricture Materials and Methods: The experiment was carried out on white male rats weighting 250-300 grams, to whom the third degree esophageal stricture model was created. After layer-by-layer incision of anterior abdominal wall abdominal portion of the esophagus was completely ligated (10 rats). In the control group (6 rats) anterior abdominal wall was opened with its subsequent layered closure. The animals were withdrawn from the experiment on the third day by ketamine overdose, and the samples were taken for ultrastructural study. Electron microscopic study of submicroscopic organization of basal, prickle, superficial epithelial cells in stratified non-squamous epithelium, smooth myocytes of muscle plate and contractile elements in esophageal muscular layer was carried out. Nuclear membrane, membranes of mitochondria, endoplasmic reticulum and cytoplasmic Golgi complex were found to be subjected to focal lysis. The third degree esophageal stricture caused destructive lesions in ultrastructural architectonics of stratified non-squamous epithelium cells, smooth myocytes of muscle plate and contractile elements in esophageal muscular layer of rats. Thus, catabolic processes leading to organelle disintegration develop in esophageal cells of rats with third degree stricture.

The incidence of anal cancer among HIV-infected patients is higher than that in other populations. Anal high-grade squamous intraepithelial lesions are considered precursors to invasive squamous-cell carcinomas and are strongly associated to high-risk human papillomavirus infection. The aim of this study is to determine the prevalence of anal high-grade squamous intraepithelial lesions through screening based on cytology and high-resolution anoscopy with biopsy in a cohort of HIV-infected men who have sex with men. This investigation is an observational cross-sectional cohort study. The study was conducted in the HIV unit of a tertiary hospital in Spain. Three hundred HIV-infected men who have sex with men participated. Physical examination led to a diagnosis of perianal squamous-cell carcinoma and high-grade squamous intraepithelial lesions in 2 patients who were then excluded. Anal liquid cytology was performed. Patients with cytological abnormalities underwent high-resolution anoscopy and biopsy. The primary outcome measured was biopsy-proven high-grade squamous intraepithelial lesions. The median age was 41 ± 10.5 years. The mean and nadir CD4 cell counts were 651 ± 205 cells/mm(3) (interquartile range, 438-800) and 273 ± 205 cells/mm(3) (interquartile range, 131-362). High-risk human papillomavirus was detected in 80.9% of patients, and human papillomavirus 16 was detected in 35.9% of patients. The mean number of human papillomavirus genotypes was 4.6 ± 2.9 (CI, 2-6). Anal cytology was abnormal in 40.9% of patients (n = 122/298; interquartile range, 35.4%-46.6%). High-resolution anoscopy and biopsies were performed in 119 patients. The results of histological analyses were as follows: normal, 7.7% (n = 23); condyloma, 4.3% (n = 13); anal intraepithelial neoplasia 1, 5.7% (n = 17); anal intraepithelial neoplasia 2, 14% (n = 42); and anal intraepithelial neoplasia 3, 8% (n = 24). The overall prevalence of high-grade squamous intraepithelial lesions among patients with abnormal cytology was 54% (95% CI, 45.1%-62.8%). A diagnosis of high-grade squamous intraepithelial lesions was associated with human papillomavirus 16 and human papillomavirus 51 infection, and with detection of a higher number of human papillomavirus genotypes. High-resolution anoscopy was only performed in patients with abnormal cytology. The prevalence of high-risk human papillomavirus infection and high-grade squamous intraepithelial lesions is high in our cohort. Physical examination enabled straightforward diagnosis of perianal high-grade squamous intraepithelial lesions and squamous-cell carcinoma in 2 patients.

Hydrothorax, as one of the common complications of malignant tumors, still cannot be sensitively detected in clinical practice, thus requiring a sensitive, specific method for diagnosis. The aim of this study was to analyze the correlation between levels of vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) in patients with benign and malignant hydrothorax. The contents of VEGF in the pleural effusion and serum of the patients with malignant pleural effusion (n = 35) and benign pleural effusion (n = 30) were detected by double antibody sandwich enzyme linked immunosorbent assay. The gene copy number level of EGFR in pleural effusion was detected by fluorescence in situ hybridization (FISH). The points with the highest sensitivity and specificity were selected as the critical values to calculate the diagnostic value of the VEGF in pleural effusion and serum, and EGFR gene copy number in pleural effusion. The contents of VEGF in pleural effusion and serum of patients with malignant hydrothorax were (384.91 ± 120.18), and (129.62 ± 46.35) ng/L, respectively, which were significantly higher than those of the patients with benign hydrothorax (207.97 ± 64.04), (63.49 ± 24.58) ng/L (P < 0.01). The sensitivity and specificity of detecting VEGF in pleural effusion were 80.0% and 96.7% (the boundary value was 297.06 ng/L), respectively for diagnosing benign and malignant hydrothorax. The sensitivity and specificity of serum were 74.3% and 96.7%, respectively (the boundary value was 99.21 ng/L) for diagnosing benign and malignant hydrothorax. The diagnostic efficiencies of EGFR and VEGF in hydrothorax were similar. There was a significant correlation between EGFR and VEGF in hydrothorax (P < 0.01). VEGF and EGFR play important roles in the formation of pleural effusion. VEGF differed significantly in benign and malignant pleural effusions, which contributed to differential diagnosis results of benign and malignant pleural effusions. It is feasible to detect the gene copy number of the pleural effusion cell mass EGFR by FISH technique. Joint detection can improve the diagnostic sensitivity.

Abstract In carcinoma, such as of the lung, the histological subtype is important to select an appropriate therapeutic strategy for patients. However, carcinomas with poor differentiation cannot always be distinguished on the basis of morphology alone nor on clinical findings. Hence, delineation of poorly differentiated adenocarcinoma and squamous cell carcinoma, the 2 most common epithelial-origin carcinomas, is pivotal for selection of optimum therapy. Herein, we explored the potential utility of trefoil factor 3 (TFF3) as a biomarker for primary lung adenocarcinoma and extrapulmonary adenocarcinomas derived from different organs. We observed that 90.9% of lung adenocarcinomas were TFF3-positive, whereas no expression of TFF3 was observed in squamous cell carcinomas. The subtype of lung carcinoma was confirmed by four established biomarkers, cytokeratin 7 and thyroid transcription factor 1 for adenocarcinoma and P63 and cytokeratin 5/6 for squamous cell carcinoma. Furthermore, expression of TFF3 mRNA was observed by quantitative PCR in all of 11 human lung adenocarcinoma cell lines and highly correlated with markers of the adenocarcinomatous lineage. In contrast, little or no expression of TFF3 was observed in 4 lung squamous cell carcinoma cell lines. By use of forced expression, or siRNA-mediated depletion of TFF3, we determined that TFF3 appeared to maintain rather than promote glandular differentiation of lung carcinoma cells. In addition, TFF3 expression was also determined in adenocarcinomas from colorectum, stomach, cervix, esophagus, and larynx. Among all these extrapulmonary carcinomas, 93.7% of adenocarcinomas exhibited TFF3 positivity, whereas only 2.9% of squamous cell carcinomas were TFF3-positive. Totally, 92.9% of both pulmonary and extrapulmonary adenocarcinomas exhibited TFF3 positivity, whereas only 1.5% of squamous cell carcinomas were TFF3-positive. In conclusion, TFF3 is preferentially expressed in adenocarcinoma and may function as an additional biomarker for distinguishing adenocarcinoma from squamous cell carcinoma. PMID:25997063

High-resolution anoscopy has been shown to improve identification of anal intraepithelial neoplasia but a reduction in progression to anal squamous-cell cancer has not been substantiated when serial high-resolution anoscopy is compared with traditional expectant management. The aim of this study was to compare high-resolution anoscopy versus expectant management for the surveillance of anal intraepithelial neoplasia and the prevention of anal cancer. This is a retrospective review of all patients who presented with anal squamous dysplasia, positive anal Pap smears, or anal squamous-cell cancer from 2007 to 2013. This study was performed in the colorectal department of a university-affiliated, tertiary care hospital. Included patients had biopsy-proven anal intraepithelial neoplasia from 2007 to 2013. Patients were treated with high-resolution anoscopy with ablation or standard anoscopy with ablation. Both groups were treated with imiquimod and followed every 6 months indefinitely. The incidence of anal squamous-cell cancer in each group was the primary end point. From 2007 to 2013, 424 patients with anal squamous dysplasia were seen in the clinic (high-resolution anoscopy, 220; expectant management, 204). Three patients (high-resolution anoscopy, 1; expectant management, 2) progressed to anal squamous-cell cancer; 2 were noncompliant with follow-up and with HIV treatment, and the third was allergic to imiquimod and refused to take topical 5-fluorouracil. The 5-year progression rate was 6.0% (95% CI, 1.5-24.6) for expectant management and 4.5% (95% CI, 0.7-30.8) for high-resolution anoscopy (p = 0.37). This was a retrospective review. There is potential for selection and referral bias. Because of the rarity of the outcome, the study may be underpowered. Patients with squamous-cell dysplasia followed with expectant management or high-resolution anoscopy rarely develop squamous-cell cancer if they are compliant with the protocol. The cost, morbidity, and value of high-resolution anoscopy should be further evaluated in lieu of these findings.

The current study was conducted to develop a multifactorial statistical model to predict the specific head and neck (H&N) tumor site origin in cases of squamous cell carcinoma confined to the cervical lymph nodes ("unknown primaries"). The Surveillance, Epidemiology, and End Results (SEER) database was analyzed for patients with an H&N tumor site who were diagnosed between 2004 and 2011. The SEER patients were identified according to their H&N primary tumor site and clinically positive cervical lymph node levels at the time of presentation. The SEER patient data set was randomly divided into 2 data sets for the purposes of internal split-sample validation. The effects of cervical lymph node levels, age, race, and sex on H&N primary tumor site were examined using univariate and multivariate analyses. Multivariate logistic regression models and an associated set of nomograms were developed based on relevant factors to provide probabilities of tumor site origin. Analysis of the SEER database identified 20,011 patients with H&N disease with both site-level and lymph node-level data. Sex, race, age, and lymph node levels were associated with primary H&N tumor site (nasopharynx, hypopharynx, oropharynx, and larynx) in the multivariate models. Internal validation techniques affirmed the accuracy of these models on separate data. The incorporation of epidemiologic and lymph node data into a predictive model has the potential to provide valuable guidance to clinicians in the treatment of patients with squamous cell carcinoma confined to the cervical lymph nodes. © 2014 The Authors.

Automated extraction of pleural effusion in three-dimensional thoracic CT images

It is important for diagnosis of pulmonary diseases to measure volume of accumulating pleural effusion in threedimensional thoracic CT images quantitatively. However, automated extraction of pulmonary effusion correctly is difficult. Conventional extraction algorithm using a gray-level based threshold can not extract pleural effusion from thoracic wall or mediastinum correctly, because density of pleural effusion in CT images is similar to those of thoracic wall or mediastinum. So, we have developed an automated extraction method of pulmonary effusion by use of extracting lung area with pleural effusion. Our method used a template of lung obtained from a normal lung for segmentation of lungs with pleural effusions. Registration process consisted of two steps. First step was a global matching processing between normal and abnormal lungs of organs such as bronchi, bones (ribs, sternum and vertebrae) and upper surfaces of livers which were extracted using a region-growing algorithm. Second step was a local matching processing between normal and abnormal lungs which were deformed by the parameter obtained from the global matching processing. Finally, we segmented a lung with pleural effusion by use of the template which was deformed by two parameters obtained from the global matching processing and the local matching processing. We compared our method with a conventional extraction method using a gray-level based threshold and two published methods. The extraction rates of pleural effusions obtained from our method were much higher than those obtained from other methods. Automated extraction method of pulmonary effusion by use of extracting lung area with pleural effusion is promising for diagnosis of pulmonary diseases by providing quantitative volume of accumulating pleural effusion.

Subarachnoidal-pleural fistula (SAPF) as an unusual cause of persistent pleural effusion. Beta-trace protein as a marker for SAPF. Case report and review of the literature.

We describe a case of a 56-year-old woman who developed a recurrent pleural effusion after a thoracoscopic resection of an anterior bulging thoracic disc hernia (level D9-D10). Despite several evacuating pleural punctions, dyspnea reoccurred due to recurrent pleural effusion, the same side as the disc resection. Because of increasing headache after each punction, a subarachnoidal pleural fistula (SAPF) was suspected. Although magnetic resonance imaging (MRI) showed features suggestive of SAPF, there was not enough evidence to justify a new thorascopy. Cerebrospinal fluid (CSF) leakage into the thoracic and abdominal cavity has been described as a result of trauma or surgery. Detection of beta-trace protein (BTP, a brain-specific protein) has been described to detect CSF fistulae causing rhino- and otoliquorrhea. Similarly, BTP determination could be used to identify the presence of CSF at other anatomical sites such as the thoracic cavity. Therefore, we decided to determine the concentration of BTP in the pleural effusion of this patient. BTP was assayed using immunonephelometry. The patient's BTP pleural fluid concentration was 14·0 mg/l, which was a 25-fold increase compared with the BTP serum concentration. After insertion of a subarachnoidal lumbal catheter, a video-assisted thorascopy was performed. Leakage of liquor through the parietal pleura into the thoracic cavity was observed. The SAPF was closed using a durasis patch and DuraSeal®. Postoperatively, there was no reoccurrence of pleural fluid. SAPF has to be included to the differential diagnosis of patients with persistent pleural effusion after spinal surgery. This case illustrates the importance of BTP in diagnosing SAPF, especially in cases where major therapeutic consequences may need to be drawn.

Pleural mesothelial cells in pleural and lung diseases

PubMed Central

Antony, Veena B.

During development, the mesoderm maintains a complex relationship with the developing endoderm giving rise to the mature lung. Pleural mesothelial cells (PMCs) derived from the mesoderm play a key role during the development of the lung. The pleural mesothelium differentiates to give rise to the endothelium and smooth muscle cells via epithelial-to-mesenchymal transition (EMT). An aberrant recapitulation of such developmental pathways can play an important role in the pathogenesis of disease processes such as idiopathic pulmonary fibrosis (IPF). The PMC is the central component of the immune responses of the pleura. When exposed to noxious stimuli, it demonstrates innate immune responses such as Toll-like receptor (TLR) recognition of pathogen associated molecular patterns as well as causes the release of several cytokines to activate adaptive immune responses. Development of pleural effusions occurs due to an imbalance in the dynamic interaction between junctional proteins, n-cadherin and β-catenin, and phosphorylation of adherens junctions between PMCs, which is caused in part by vascular endothelial growth factor (VEGF) released by PMCs. PMCs play an important role in defense mechanisms against bacterial and mycobacterial pleural infections, and in pathogenesis of malignant pleural effusion, asbestos related pleural disease and malignant pleural mesothelioma. PMCs also play a key role in the resolution of inflammation, which can occur with or without fibrosis. Fibrosis occurs as a result of disordered fibrin turnover and due to the effects of cytokines such as transforming growth factor-β, platelet-derived growth factor (PDGF), and basic fibroblast growth factor; which are released by PMCs. Recent studies have demonstrated a role for PMCs in the pathogenesis of IPF suggesting their potential as a cellular biomarker of disease activity and as a possible therapeutic target. Pleural-based therapies targeting PMCs for treatment of IPF and other lung diseases need further exploration. PMID:26150910

The preservation of pleural integrity during mammary artery harvesting may decrease atelectasis and pleural effusion during the postoperative period. We designed this retrospective study to evaluate the effects on postoperative pulmonary function of pleural integrity versus opened pleura, in patients who receive a left internal mammary artery graft. The study group consisted of 1,141 patients who underwent elective coronary artery bypass grafting. The patients were retrospectively evaluated and divided into 2 groups: those who underwent internal mammary artery harvesting with opened pleura (n=873) or with pleural integrity (n=268). To monitor pleural effusion and atelectasis, chest radiography was performed routinely 1 day before operation and on the 2nd, 5th, and 7th postoperative days. The preoperative, after extubation, and 1st postoperative day values of partial oxygen pressure (PaO2), partial carbon dioxide pressure (PaCO2), and oxygen (O2) saturation were recorded for comparison, as was the hematocrit. The mean age of the patients was 57.4 ± 8.81 years. There were no significant differences between the groups in mean values of PaO2, PaCO2, O2 saturation, and hematocrit after extubation or on the 1st postoperative day. Atelectasis on the 5th and 7th postoperative days, pleural effusion on the 2nd, 5th, and 7th days, and postoperative bleeding were significantly less in the group with preserved pleural integrity. We showed that preservation of pleural integrity during internal mammary artery harvesting decreases postoperative bleeding, pleural effusion, and atelectasis. We conclude that preservation of pleural integrity, when possible, can decrease these postoperative complications of coronary artery bypass grafting. PMID:16878610

To assess the prevalence of non-malignant chest x ray abnormalities in cases of mesothelioma 184 cases of mesothelioma (72 pleural and 112 peritoneal) which had occurred in a cohort of asbestos insulation workers followed up since 1967 were studied. Chest x ray films of satisfactory quality, on which the presence or absence of non-malignant radiological changes indicating interstitial pulmonary fibrosis or pleural fibrosis or both, could be assessed with a high degree of certainty were available. In some cases (20% for pleural mesothelioma, 11.6% for peritoneal mesothelioma) non-malignant radiological changes were not radiologically detectable. Parenchymal interstitial fibrosis (small irregular opacities) only was found in a proportion of cases (25.4% of pleural mesotheliomas, 12.5% of peritoneal mesotheliomas). Pleural fibrosis only was detected in 17% of cases of pleural mesothelioma and 27% of cases of peritoneal mesothelioma. Most patients had both parenchymal and pleural fibrosis. Although these results tend to indicate that in peritoneal mesothelioma the proportion of pleural fibrosis is significantly higher, these findings might have been due to the fact that in most cases of pleural mesothelioma non-malignant changes were interpreted in one hemithorax only. In 46 cases (21 pleural, 25 peritoneal) in which sufficient lung tissue was available histopathology of lung parenchyma indicated the presence of interstitial fibrosis; in 20 (43.5%) of these the chest x ray film had been read as negative. Thus the absence of radiologically detectable small opacities on the chest x ray film does not exclude the existence of interstitial pulmonary fibrosis in cases of mesothelioma among insulation workers. With lower levels of exposure (such as in family contacts of asbestos workers) it is conceivable that mesothelioma might occur in the absence of interstitial pulmonary fibrosis. PMID:3606969

Data regarding pleural effusion due to pulmonary embolism (PE) are limited. The aim of this study was to investigate the clinical characteristics of PE patients with pleural effusion caused by PE. Patients with PE were retrospectively analyzed and divided into 2 groups based on computed tomography: a group with pleural effusion due to PE (effusion group) and a group without pleural effusion (control group). Clinical characteristics were compared between the 2 groups. The study population consisted of the effusion group (n = 127) and the control group (n = 651). Serum C-reactive protein (CRP) level was significantly higher in the effusion group than in the control group. The percentages of high-risk Simplified PE Severity Index (57 vs. 47%, p = 0.008), central PE (84 vs. 73%, p = 0.013), right ventricular dilation (45 vs. 36%, p = 0.053), and pulmonary infarction (40 vs. 8%, p < 0.001) were higher in the effusion group than in the control group. Multivariate analysis demonstrated that pulmonary infarction (odds ratio [OR] 6.20, 95% confidence interval [CI] 3.49-10.91, p < 0.001) and CRP level (OR 1.05, 95% CI 1.101-1.09, p = 0.023) were independent predictors of pleural effusion due to PE. The presence of pleural effusion was not a predictor of short-term outcomes or length of hospital stay. Patients with more severe PE are likely to have pleural effusion caused by PE. However, pleural effusion was not a proven predictor of short-term outcome or length of hospital stay. Pulmonary infarction and CRP levels were independent risk factors for the development of pleural effusion. © 2017 S. Karger AG, Basel.

Introduction Previous studies have assessed the diagnostic ability of pleural fluid adenosine deaminase (pfADA) in detecting tuberculous pleural effusions, with good specificity and sensitivity reported. However, in North Western Europe pfADA is not routinely used in the investigation of a patient with an undiagnosed pleural effusion, mainly due to a lack of evidence as to its utility in populations with low mycobacterium tuberculosis (mTB) incidence. Methods Patients presenting with an undiagnosed pleural effusion to a tertiary pleural centre in South-West England over a 3 year period, were prospectively recruited to a pleural biomarker study. Pleural fluid from consecutive patients with robust 12-month follow up data and confirmed diagnosis were sent for pfADA analysis. Results Of 338 patients enrolled, 7 had confirmed tuberculous pleural effusion (2%). All mTB effusions were lymphocyte predominant with a median pfADA of 72.0 IU/L (range- 26.7 to 91.5) compared to a population median of 12.0 IU/L (range- 0.3 to 568.4). The optimal pfADA cut off was 35 IU/L, which had a negative predictive value (NPV) of 99.7% (95% CI; 98.2-99.9%) for the exclusion of mTB, and sensitivity of 85.7% (95% CI; 42.2-97.6%) with an area under the curve of 0.88 (95% CI; 0.732–1.000). Discussion This is the first study examining the diagnostic utility of pfADA in a low mTB incidence area. The chance of an effusion with a pfADA under 35 IU/L being of tuberculous aetiology was negligible. A pfADA of over 35 IU/L in lymphocyte-predominant pleural fluid gives a strong suspicion of mTB.

Localized malignant pleural mesothelioma is very rare tumor disease. There are sporadic reports in the literature showing that this entity has a different biologic behavior compared with diffuse pleural mesothelioma. We report two cases of radically resected localized pleural malignant mesothelioma, with a previous history of asbestos exposure. Both cases showed a microscopic and immunohistochemical findings of malignant mesothelioma, biphasic and sarcomatoid lympho-histiocitoid variant type, respectively, without evidence of diffuse pleural spread. The first is very peculiar case of bilateral localized malignant pleural mesothelioma with complete response to chemotherapy and localized late recurrence, radically resected and treated with adjuvant radiotherapy. The second case revealed as a solitary localized mass, underwent a complete en bloc resection and adjuvant radiotherapy. Both cases demonstrate that the localized malignant mesothelioma should be distinguished from diffuse form and that complete resection is associated with good prognosis.

Summary Background: Pleural mesothelioma is a very rare neoplasm; especially the local form. The diagnostics is difficult and the prognosis unfavourable. Case Report: We presented a case of a man with dyspnoea and cough. His chest radiogram showed hydrothorax on the left side. Neither the examinations of the pleural liquid, nor the CT-guided fine needle biopsy established the diagnosis. CT showed features suggestive of pleural mesothelioma. The diagnosis was confirmed by thoracoscopy. Although no neoplastic cells were found in the thoracoscopic specimen from the supradiaphragmatic tumor, we assumed that to be a case of a diffuse, primarily local form of mesothelioma. Conclusions: Diagnostics of pleural mesothelioma is very difficult. CT and thoracoscopy seem to be very valuable diagnostic methods. It is worth remembering that pleural mesothelioma can have a local form which may transform into a diffuse one. PMID:22802809

Malignant pleural mesothelioma incidence continues to rise, with few available evidence-based therapeutic options. Results of previous non-randomised studies suggested that video-assisted thoracoscopic partial pleurectomy (VAT-PP) might improve symptom control and survival. We aimed to compare efficacy in terms of overall survival, and cost, of VAT-PP and talc pleurodesis in patients with malignant pleural mesothelioma. We undertook an open-label, parallel-group, randomised, controlled trial in patients aged 18 years or older with any subtype of confirmed or suspected mesothelioma with pleural effusion, recruited from 12 hospitals in the UK. Eligible patients were randomly assigned (1:1) to either VAT-PP or talc pleurodesis by computer-generated random numbers, stratified by European Organisation for Research and Treatment of Cancer risk category (high vs low). The primary outcome was overall survival at 1 year, analysed by intention to treat (all patients randomly assigned to a treatment group with a final diagnosis of mesothelioma). This trial is registered with ClinicalTrials.gov, number NCT00821860. Between Oct 24, 2003, and Jan 24, 2012, we randomly assigned 196 patients, of whom 175 (88 assigned to talc pleurodesis, 87 assigned to VAT-PP) had confirmed mesothelioma. Overall survival at 1 year was 52% (95% CI 41-62) in the VAT-PP group and 57% (46-66) in the talc pleurodesis group (hazard ratio 1·04 [95% CI 0·76-1·42]; p=0·81). Surgical complications were significantly more common after VAT-PP than after talc pleurodesis, occurring in 24 (31%) of 78 patients who completed VAT-PP versus ten (14%) of 73 patients who completed talc pleurodesis (p=0·019), as were respiratory complications (19 [24%] vs 11 [15%]; p=0·22) and air-leak beyond 10 days (five [6%] vs one [1%]; p=0·21), although not significantly so. Median hospital stay was longer at 7 days (IQR 5-11) in patients who received VAT-PP compared with 3 days (2-5) for those who received talc pleurodesis (p<0·0001). VAT-PP is not recommended to improve overall survival in patients with pleural effusion due to malignant pleural mesothelioma, and talc pleurodesis might be preferable considering the fewer complications and shorter hospital stay associated with this treatment.

The clinical relevance of pleural effusions in lung cancer has seldom been approached systematically. The aim of this study was to determine the prevalence, causes and natural history of lung cancer-associated pleural effusions, as well as their influence on survival. Retrospective review of clinical records and imaging of 556 consecutive patients with a newly diagnosed lung cancer over a 4-year period at our institution. Lung cancer comprised 490 non-small cell and 66 small cell types. About 40% of patients with lung cancer developed pleural effusions at some time during the course of their disease. In half the patients, the effusions were too small to be tapped. These effusions did not progress to require a pleural intervention. Patients with minimal effusions had a worse prognosis compared to patients without pleural effusions (median survival of 7.49 vs 12.65 months, P < 0.001). Less than 20% of the 113 patients subjected to a diagnostic thoracentesis had benign causes for their effusions. Palliative pleural procedures (like therapeutic thoracenteses, pleurodesis or tunnelled pleural catheters) were conducted in 79 (84%) of the 94 malignant effusions. An effusion's size equal to or greater than half of the hemithorax was a strong predictor of the need for a palliative procedure. Overall survival of patients with malignant effusions was 5.49 months. Malignant pleural effusions are a poor prognostic factor in the setting of lung cancer, which includes minimal effusions not amenable to tapping. © 2015 Asian Pacific Society of Respirology.

Malignant pleural effusion (MPE) appears in up to 20% of patients with non-Hodgkin's lymphoma (NHL). The present study aimed to assess the efficacy of medical thoracoscopy (MT) in the diagnosis of patients with MPE induced by NHL. Between July 2005 and June 2014, 833 patients with pleural effusions of unknown etiology underwent MT in Beijing Chaoyang Hospital (Beijing, China), where diagnostic thoracocentesis or/and blind pleural biopsy had failed to yield an answer. Demographic, radiographic, thoracoscopic, histological and immunophenotyping data of 10 NHL patients with MPE were then retrospectively analyzed. Under medical thoracoscopy, pleural nodules (in n=6 patients), hyperemia (n=5), plaque-like lesions (n=4), pleural thickening (n=3), cellulose (n=3), ulcer (n=2), adhesion (n=2), and scattered hemorrhagic spots (n=1) were observed on the surface of parietal pleura. Histopathological and immunohistochemical analysis of pleural biopsy samples led to a correct diagnosis of B-cell NHL in 7 patients and T-lymphoblastic NHL in 2 patients. Data from the present study demonstrated that pleural biopsy through MT achieved a definite diagnosis of NHL in 9 out of 10 (90%) patients with MPE induced by NHL. Therefore, MT is a useful method for diagnosing MPE induced by NHL. PMID:29344253

Pleural thickenings are caused by asbestos exposure and may evolve into malignant pleural mesothelioma. An early diagnosis plays a key role towards an early treatment and an increased survival rate. Today, pleural thickenings are detected by visual inspection of CT data, which is time-consuming and underlies the physician's subjective judgment. A computer-assisted diagnosis system to automatically assess pleural thickenings has been developed, which includes not only a quantitative assessment with respect to size and location, but also enhances this information with an anatomical description, i.e. lung side (left, right), part of pleura (pars costalis, mediastinalis, diaphragmatica, spinalis), as well as vertical (upper, middle, lower) and horizontal (ventral, dorsal) position. For this purpose, a 3D anatomical model of the lung surface has been manually constructed as a 3D atlas. Three registration sub-steps including rigid, affine, and nonrigid registration align the input patient lung to the 3D anatomical atlas model of the lung surface. Finally, each detected pleural thickening is assigned a set of labels describing its anatomical properties. Through this added information, an enhancement to the existing computer-assisted diagnosis system is presented in order to assure a higher precision and reproducible assessment of pleural thickenings, aiming at the diagnosis of the pleural mesothelioma in its early stage.

Mast cells (MCs) have been identified in various tumors; however, the role of these cells in tumorigenesis remains controversial. Here, we quantified MCs in human and murine malignant pleural effusions (MPEs) and evaluated the fate and function of these cells in MPE development. Evaluation of murine MPE-competent lung and colon adenocarcinomas revealed that these tumors actively attract and subsequently degranulate MCs in the pleural space by elaborating CCL2 and osteopontin. MCs were required for effusion development, as MPEs did not form in mice lacking MCs, and pleural infusion of MCs with MPE-incompetent cells promoted MPE formation. Once homed to the pleural space, MCs released tryptase AB1 and IL-1β, which in turn induced pleural vasculature leakiness and triggered NF-κB activation in pleural tumor cells, thereby fostering pleural fluid accumulation and tumor growth. Evaluation of human effusions revealed that MCs are elevated in MPEs compared with benign effusions. Moreover, MC abundance correlated with MPE formation in a human cancer cell-induced effusion model. Treatment of mice with the c-KIT inhibitor imatinib mesylate limited effusion precipitation by mouse and human adenocarcinoma cells. Together, the results of this study indicate that MCs are required for MPE formation and suggest that MC-dependent effusion formation is therapeutically addressable.

Chronic eosinophilic pneumonia is a rare idiopathic interstitial lung disease. The nearly pathognomonic radiographic finding is the peripheral distribution of alveolar opacities. Pleural effusions are rarely seen. We report a case of chronic eosinophilic pneumonia with transudative eosinophilic pleural effusion. A 57-year-old Hispanic woman, a nonsmoker with a history of controlled asthma, presented to the hospital with unresolving pneumonia despite three rounds of antibiotics over a 2-month period. She was later diagnosed with chronic eosinophilic pneumonia based on the presence of peripheral blood eosinophilia, the peripheral distribution of alveolar infiltrates on chest radiograph, and a lung parenchymal biopsy with infiltrates of eosinophils. Upon presentation, our patient had a right-sided moderate-sized pleural effusion. The pleural fluid profile was consistent with a transudative effusion with eosinophil predominance. Our patient responded promptly to oral corticosteroid treatment in a few days. The pulmonary infiltrates and pleural effusion subsided on a 1-month follow-up chest radiograph after starting corticosteroid treatment. We report the first case of chronic eosinophilic pneumonia presenting with pneumonia with ipsilateral transudative eosinophilic pleural effusion. Like other cases of chronic eosinophilic pneumonia, early recognition and diagnosis is essential and prompt treatment with corticosteroids is the mainstay of therapy. Pleural effusion resolved without the further need for therapeutic thoracentesis.

Congestive heart failure (CHF) in cats with left-sided heart disease is sometimes manifest as pleural effusion, in other cases as pulmonary edema. Those cats with pleural effusion have more severe left atrial (LA) dysfunction than cats with pulmonary edema. 30 healthy cats, 22 cats with pleural effusion, and 12 cats with pulmonary edema. All cats were client owned. Retrospective study. Measurements of LA size and function were made using commercial software on archived echocardiograms. Cases were identified through searches of medical records and of archived echocardiograms for cats with these conditions. There was no difference (P = .3) in LA size between cats with pleural effusion and cats with pulmonary edema. Cats with pleural effusion had poorer (P = .04) LA active emptying and increased (P = .006) right ventricular (RV) diameter when compared with cats with pulmonary edema and healthy cats. Cats that exhibited LA active emptying of <7.9%, total emptying of <13.6% (diameter) or <19.4% (area), or RV diameter of >3.6 mm were significantly (P < .001) more likely to manifest pleural effusion. Poorer LA function and increased RV dimensions are associated with pleural effusion in cats with left-sided heart disease. Copyright © 2012 by the American College of Veterinary Internal Medicine.

Cholesterol and carcinoembryonic antigen (CEA) levels in pleural effusion and sera, were measured in 199 patients with pleural effusions of various origins. Malignant cause was found in 93, and nonmalignant in 106 patients. Mean cholesterol level in sera of patient with malignant disease was 5.0 +/- 0.93 mmol/L, and in nonmalignant group 4.34 +/- 1.32 mmol/L. The difference was not statistically significant. Mean cholesterol level in nonmalignant pleural effusions was higher thAn those in malignant (2.51 +/- 1.23 mmol/L; and 2.28 +/- 1.06 mmol/L), but the difference was also not significant. Average pleural fluid/serum cholesterol ratio (Holl/S) in nonmalignant group was 0.61 +/- 0.32 and in malignant group 0.46 +/- 0.22. The difference between those mean values was significant. Higher ratio, at the cut off value of 0.5 was found in 79/106 and in 25/93 malignant patients. Calculated sensitivity was 75%, specificity 73%, positive predictive value 76%, negative predictive value 65% and accuracy 69%. Significant negative correlation between Holi/S and pleural fluid CEA was found (p < 0.05). It was assumed that pleural fluid/serum cholesterol ratio lower than 0.5 could be of great benefit, as an additional test in the differentiation of malignant from benign pleural effusion.

Pneumonia is the second most common cause of pleural effusion. The presence of pleural fluid makes the prognosis in patients with pneumonia worse and causes a higher mortality rate. This is why it is very important to undertake suitable treatment as soon as possible. Most parapneumonic pleural effusions resolve with antibiotic alone, but sometimes more invasive treatment is necessary. Therapeutic decisions are based on different criteria. For many years determining biochemical fluid characteristics has been used for this purpose. Presentlythe usefullness of new parameters is being evaluated. Their application in diagnostics was possible thanks to better knowledge of mechanisms that participate in the development of parapneumonic pleural effusion.

We report an atypical case of Rhodotorula mucilaginosa fungemia coexisting with pleural tuberculosis, in an immunocompetent host. The patient was an inhaled drug abuser and worked in a fruit market. The diagnosis of Rhodotorula mucilaginosa infection was established by the isolation of the yeast in two blood cultures followed by a good response to amphotericin B treatment. Persistent evening fever and pleural effusion led to the second diagnosis-pleural tuberculosis. In the last 5 years, this was the only case of Rhodotorula mucilaginosa fungemia in our hospital and the first case in the literature that documents Rhodotorula mucilaginosa fungemia associated with pleural tuberculosis.

The pleural space provides the mechanical coupling between lung and chest wall: two views about this coupling are reported and discussed. Information on volume, composition, thickness, and pressure of the pleural liquid under physiologic conditions in a few species is provided. The Starling pressures of the parietal pleura filtering liquid into pleural space, and those of the visceral pleura absorbing liquid from the space are considered along with the permeability of the mesothelium. Information on the lymphatic drainage through the parietal pleura and on the solute-coupled liquid absorption from the pleural space under physiologic conditions and with various kinds of hydrothorax are provided.

Pleural fluid effusion particularly chylothorax is a relatively rare occurrence in the newborn, but when it occurs it is often life-threatening. In this article, we describe and illustrate the morphologic features of the visceral and parietal pleura including pleural lymphatics and the physiology and pathophysiology of pleural fluid balance. The role and function of the lymphatic system in controlling the volume and composition of pleural liquid are detailed and a conceptual scheme presented. Finally, the crucial role of inadequate lymphatic drainage (either functional overload from an imbalance in Starling forces or mechanical insufficiency from lymphatic dysplasia) is emphasized.

Switching off malignant pleural effusion formation—fantasy or future?

PubMed Central

Giannou, Anastasios D.; Stathopoulos, Georgios T.

2015-01-01

Malignant pleural effusion (MPE) is common and difficult to treat. In the vast majority of patients the presence of MPE heralds incurable disease, associated with poor quality of life, morbidity and mortality. Current therapeutic approaches are inefficient and merely offer palliation of associated symptoms. Recent scientific progress has shed light in the biologic processes governing the mechanisms behind the pathobiology of MPE. Pleural based tumors interfere with pleural fluid drainage, as well as the host vasculature and immune system, resulting in decreased fluid absorption and increased pleural fluid production via enhanced plasma extravasation into the pleural space. In order to achieve this feat, pleural based tumors must elicit critical vasoactive events in the pleura, thus forming a favorable microenvironment for tumor dissemination and MPE development. Such properties involve specific transcriptional signaling cascades in addition to secretion of important mediators which attract and activate host cell populations which, in turn, impact tumor cell functions. The dissection of the biologic steps leading to MPE formation provides novel therapeutic targets and recent research findings provide encouraging results towards future therapeutic innovations in MPE management.

Pleural photodynamic therapy (PDT) has been used as an adjuvant treatment with lung-sparing surgical treatment for malignant pleural mesothelioma (MPM). In the current pleural PDT protocol, a moving fiber-based point source is used to deliver the light. The light fluences at multiple locations are monitored by several isotropic detectors placed in the pleural cavity. To improve the delivery of light fluence uniformity, an infrared (IR) navigation system is used to track the motion of the light source in real-time at a rate of 20 - 60 Hz. A treatment planning system uses the laser source positions obtained from the IR camera to calculate light fluence distribution to monitor the light dose uniformity on the surface of the pleural cavity. A novel reconstruction algorithm is used to determine the pleural cavity surface contour. A dual-correction method is used to match the calculated fluences at detector locations to the detector readings. Preliminary data from a phantom shows superior light uniformity using this method. Light fluence uniformity from patient treatments is also shown with and without the correction method.

Hydrops fetalis (fetal hydrops) is a serious fetal condition defined as abnormal accumulation of fluid in two or more extravascular compartments, including ascites, pleural effusion, pericardial effusion, and skin edema. Edema is classified as immune or non-immune. Today more than 90% of fetal edema has non-immune cause. This paper presents a case of a pregnant woman who was admitted to the Obstetrics and Gynecology Department because of fetal hydrops with massive pleural effusion and polyhydramnios at 34 weeks gestation. The intrauterine therapy consisted of two treatments. During the first surgery amnioreduction, evacuation of fluid from the pleural cavity of the fetus, and shunts to both pleural cavities were performed. During the second surgery amnioreduction, cordocentesis with albumin administration and pleural shunt were performed. Intrauterine therapy led to a reduction of swelling of the fetus from 7mm up to 1-2 mm and the total evacuation of fluid from the pleural cavity and the fetal lung expansion. We also present the condition of the neonate after birth and after 12 months of life.

Usually the pleural cavity contains a small amount of liquid (approximately 10 ml). Pleural effusions appear when the liquid production rate overpasses the absorption rate with a greater amount of liquid inside the pleural cavity. Between January 1998 to December 2008 we conducted a study in order to establish the adequate surgical treatment for MPEs. Effective control of a recurrent malignant pleural effusion can greatly improve the quality of life of the cancer patient. The present review collects and examines the clinical results of minimally invasive techniques designed to treat this problem. Patients with MPEs were studied according to several criteria. In our study we observed the superiority of intraoperative talc poudrage, probably due to a more uniform distribution of talc particles over the pleural surface. Minimal pleurotomy with thoracic drainage and instillation of a talc suspension is also a safe and effective technique and should be employed when there are contraindications for the thoracoscopic minimally invasive procedure. On the basis of comparisons involving effectiveness, morbidity, and convenience, we recommend the thoracoscopic insufflations of talc as a fine powder with pleural drainage as the procedure of choice.

Several clinical-pathological parameters have been related to survival of patients with invasive squamous cell carcinoma of the vulva, whereas few studies have investigated the ability of biological variables to predict the clinical outcome of these patients. The present paper reviews the literature data on the prognostic relevance of lymph node-related parameters, primary tumor-related parameters, FIGO stage, blood variables, and tissue biological variables. Regarding these latter, the paper takes into account the analysis of DNA content, cell cycle-regulatory proteins, apoptosis-related proteins, epidermal growth factor receptor [EGFR], and proteins that are involved in tumor invasiveness, metastasis and angiogenesis. At present, the lymph node status and FIGO stage according to the new 2009 classification system are the main predictors for vulvar squamous cell carcinoma, whereas biological variables do not have yet a clinical relevance and their role is still investigational.

2016-01-01

The factors influencing the efficacy of ultrasound-guided thoracentesis catheter drainage were investigated in the present study. A retrospective analysis of clinical data from 435 patients who presented with a pleural effusion was performed. Patients were divided into a control group and an intervention group. Thirty-seven patients in the control group were given standard care using pleural puncture to draw the excess fluid. The 398 patients in the intervention group were treated using ultrasound-guided thoracentesis catheter drainage. The rate of successful drainage of a pleural effusion was significantly higher (P<0.05), while the rate of complication was lower, in the ultrasound-guided thoracentesis cases compared to standard care treatment. In conclusion, ultrasound-guided thoracentesis catheter drainage is an efficient, safe and minimally invasive procedure to alleviate pleural effusion. The efficacy of the procedure is related to the separation of pleural effusion, drainage tube type and tube diameter. PMID:28105155

Management of Pleural Effusion, Empyema, and Lung Abscess

PubMed Central

Yu, Hyeon

2011-01-01

Pleural effusion is an accumulation of fluid in the pleural space that is classified as transudate or exudate according to its composition and underlying pathophysiology. Empyema is defined by purulent fluid collection in the pleural space, which is most commonly caused by pneumonia. A lung abscess, on the other hand, is a parenchymal necrosis with confined cavitation that results from a pulmonary infection. Pleural effusion, empyema, and lung abscess are commonly encountered clinical problems that increase mortality. These conditions have traditionally been managed by antibiotics or surgical placement of a large drainage tube. However, as the efficacy of minimally invasive interventional procedures has been well established, image-guided small percutaneous drainage tubes have been considered as the mainstay of treatment for patients with pleural fluid collections or a lung abscess. In this article, the technical aspects of image-guided interventions, indications, expected benefits, and complications are discussed and the published literature is reviewed. PMID:22379278

The aim of this review was to present the main aspects of pleural diseases seen with conventional and advanced magnetic resonance imaging (MRI) techniques. This modality is considered to be the gold standard for the evaluation of the pleural interface, characterization of complex pleural effusion, and identification of exudate and hemorrhage, as well as in the analysis of superior sulcus tumors, as it enables more accurate staging. The indication for MRI of the thorax in the identification of these conditions is increasing in comparison to computerized tomography, and it can also be used to support the diagnosis of pulmonary illnesses. This literature review describes the morphological and functional aspects of the main benign and malignant pleural diseases assessed with MRI, including mesothelioma, metastasis, lymphoma, fibroma, lipoma, endometriosis, asbestos-related pleural disease, empyema, textiloma, and splenosis.

Antiphospholipid syndrome (APS) with pleural effusion is extremely rare. A 75-year-old man was admitted to our hospital for spreading erythema on his trunk and extremities, as well as dyspnea. One year before admission, he had visited us with a 1-year history of erythema and purpura on his legs and occasional fever. Given the diagnosis of APS, we initiated a combination therapy of aspirin and warfarin, but the skin lesions had gradually worsened. A biopsy specimen revealed marked thrombosis in the dermal and subcutaneous small vessels. In addition, chest X-ray and computed tomography demonstrated a large pleural effusion in the left lung. He underwent repeated drainage of the pleural effusion but the effusion recurred. We added oral prednisolone 30 mg daily to his prior anticoagulant therapy. The skin lesions and pleural effusion rapidly improved and disappeared without any complication. Corticosteroids might be a choice of treatment for intractable pleural effusion in APS patients.

Malignant pleural effusion (PE) was generally defined as pleural effusion containing tumors with poor prognosis. Some kinds of undefined pleural effusions due to too small amount of effusion had poor prognosis too. This study aimed to analyze the clinical characteristics and prognostic factors of patients who suffered from limited-stage small cell lung cancer (LS-SCLC) complicated with pleural effusion. A retrospective analysis included 542 patients who were diagnosed with LS-SCLC and had treatment in our hospital from October 2007 to January 2016. We had observed 109 patients who were diagnosed with pleural effusion at their first visit to the doctor. We analyzed the clinical characters, survival time and the prognostic factors of the 109 patients. Our main observation targets were overall survival (OS) and progression free survival (PFS). The median OS and PFS of whole group were 29.4 and 18.2 months. Before treatment, survival time of patients with PE were significantly shorter than patients without PE (median OS: 21.0 vs 31.7 months; median PFS: 14.1 vs 9.1 months; Log-rank, P=0.001, P=0.014). Multi-factor analysis of multivariate Cox shows PE was the independent prognostic factor of LS-SCLC (P=0.04). Single factor analysis showed factors affecting PE patient's survival time included clinical stages, lymph node (LN) stages, KPS scores, pulmonary atelectasis and the state of pleural after treatment. Cox multi-factor analysis reminded that the state of pleural effusion after treatment was the independent prognostic factor of LS-SCLC complicated with pleural effusion (P=0.016). There were three groups was apportioned patients without pleural effusion before treatment (group 1; n=433), patients whose pleural effusion disappeared after treatment (group 2; n=67) and patients whose pleural effusion didn't disappear after treatment (group 3; n=32).The median OS were 31.7, 23.2, 16.8 months in the group 1, 2, 3 and the median PFS were 19.1, 17.9, 11.4 months. Obvious difference was noted by the comparison of survival time of these three groups (Log-rank P<0.001, P<0.002). The difference between group 2 and group 3 was significant (Log-rank P=0.046, P=0.013) while no obvious difference was noted during comparison of group 1 and group 2. For patients who have LS-SCLC complicated with PE, there is no remarkable difference between chemoradiotherapy and chemotherapy alone. The survival time of patients who suffered from limited-stage small cell lung cancer complicated with pleural effusion was obviously shortened. The disappearing of pleural effusion after treatment was the independent favorable prognostic factor of survival. How to treat needed further investigation.

Oral squamous cell carcinoma (OSCC) is the most common malignancy of head and neck with high mortality rates. The mechanisms of initiation and development of OSCC remain largely unknown. Dysregulated alternative splicing of pre-mRNA has been associated with OSCC. Splicing factor SRSF3 is a proto-oncogene and overexpressed in multiple cancers. The aim of this study was to uncover the relationship between SRSF3 and carcinogenesis and progression of oral squamous cell carcinoma. The expression of SRSF3 in oral normal, dysplasia, or carcinoma tissues was analyzed by immunohistochemistry. The expression levels of EMT-related genes were quantified by real-time quantitative RT-PCR. The expression of SRSF3 in DMBA treated primary cultured oral epithelial cells were analyzed by western blot. SRSF3 is overexpressed in oral cancer and moderate or severe dysplasia tissues. Patients with high grade cancer or lymphatic metastasis showed up-regulated expression of SRSF3. Knockdown of SRSF3 repressed the expression of Snail and N-cadherin in vitro. Carcinogen DMBA treated primary cultured oral epithelial cells showed significantly increased SRSF3 level than in control cells. Our results suggested that SRSF3 is associated with the initiation and development of OSCC and may be a biomarker and therapeutic target of OSCC.

To analyse the findings of multiple detector computed tomography (MDCT) after direct lymphangiography in primary intestinal lymphangiectasia (PIL). Fifty-five patients with PIL were retrospectively reviewed. All patients underwent MDCT after direct lymphangiography. The pathologies of 16 patients were confirmed by surgery and the remaining 39 patients were confirmed by gastroendoscopy and/or capsule endoscopy. After direct lymphangiography, MDCT found intra- and extraintestinal as well as lymphatic vessel abnormalities. Among the intra- and extraintestinal disorders, 49 patients had varying degrees of intestinal dilatation, 46 had small bowel wall thickening, 9 had pleural and pericardial effusions, 21 had ascites, 41 had mesenteric oedema, 20 had mesenteric nodules and 9 had abdominal lymphatic cysts. Features of lymphatic vessel abnormalities included intestinal trunk reflux (43.6%, n = 24), lumbar trunk reflux (89.1%, n = 49), pleural and pulmonary lymph reflux (14.5%, n = 8), pericardial and mediastinal lymph reflux (16.4%, n = 9), mediastinal and pulmonary lymph reflux (18.2%, n = 10), and thoracic duct outlet obstruction (90.9%, n = 50). Multiple detector computed tomography after direct lymphangiography provides a safe and accurate examination method and is an excellent tool for the diagnosis of PIL. © 2017 The Royal Australian and New Zealand College of Radiologists.

Abstract Rationale: Primary lymphomas of the uterine cervix are a rare disease. They are often misdiagnosed because of their rarity and because they can be easily confused with a squamous cell carcinoma of the cervix, as they are usually presented as exophytic mass with vaginal bleeding as their most common symptoms. Nevertheless, considering that both the prognosis and the treatment are completely different between them, differential diagnosis should be taken into account. Patient concerns: A case of a 51-year-old woman with a primary diffuse large B-cell lymphoma of the cervix is presented. Diagnoses: Diagnosis of this tumor was a challenge for pathologists and clinicians, as four biopsies were needed to achieve a final diagnosis. Interventions: Patient was successfully treated with combined Rituximab and chemotherapy (R-CHOP) alone. Outcomes: Complete remission, confirmed through biopsy, was reached after six courses of chemotherapy. At 2-years follow up, patient is alive and free of disease. Lessons: Considering that the prognosis and treatment of primary malignant lymphoma of the cervix are completely different than that of the squamous cell carcinoma, awareness of this disease should be considered in the differential diagnosis.

  Melanoma antigen (MAGE) genes are expressed in tumor cells, the testis and the placenta. The purpose of this prospective study was to investigate the sensitivity, specificity, and accuracy of the carcinoembryonic antigen (CEA), MAGE reverse transcriptase-nested polymerase chain reaction (RT-nested PCR), and cytology of pleural fluid in the diagnosis of malignant pleural effusion.   Patients in whom unilateral pleural effusion was identified on chest radiography from January to December 2009 were included in the study. MAGE genes were analyzed by RT-nested PCR using MAGE A1-6 common primers.   Of 81 enrolled patients, 46 were diagnosed as malignant pleural effusion, and 24 were diagnosed as benign pleural effusion. The diagnoses of 11 patients were not confirmed in this study. The diagnostic sensitivity, specificity, and accuracy of MAGE RT-nested PCR were 61.4%, 95.7%, and 73.1%, respectively. The diagnostic sensitivities of cytology and CEA (>5 ng/mL) were 61.4% and 75.0%, respectively. Among 17 patients with negative cytology who had malignant pleural effusion, 12 and 10 patients were positive for CEA (>5.0 ng/mL) and MAGE RT-nested PCR, respectively. However, of five patients with malignant pleural effusion that was not recognized by cytology and CEA, MAGE RT-nested PCR correctly predicted a malignant etiology in only one additional patient (20%).   MAGE RT-nested PCR seems to add little on the combination of conventional methods in the diagnosis of malignant effusion. © 2012 Tianjin Lung Cancer Institute and Wiley Publishing Asia Pty.

Matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMP) play a crucial role in physiological and pathological matrix turnover. This study aimed to determine the occurrence of MMP and TIMP in lung cancer patients with malignant pleural effusions (CA). MMP-1, MMP-2, MMP-3, MMP-8, MMP-9, TIMP-1, and IMP-2 oncentrations were determined by ELISA and zymography in pleural effusions and plasma of 31 CA and 14 congestive heart failure (CHF) patients and in plasma of 18 healthy controls (CON). MMP-2, TIMP-1, and TIMP-2 ELISA-concentrations were increased in CA pleural fluid vs. CA plasma (p < 0.005, p < 0.005, p < 0.05), in contrast to MMP-9 being higher in plasma (p < 0.005). Pleural fluid MMP-1 and MMP-8 were increased in CA vs. CHF (p < 0.05, p < 0.005). MMP and TIMP plasma concentrations were not different in CA vs. CHF, but MMP-9, TIMP-1, and TIMP-2 were increased vs. CON (p < 0.005, each). Gelatine zymography MMP-9/MMP-2 ratios were increased in CA plasma vs. effusion fluid (p < 0.005), in CA vs. CHF plasma, CA vs. CHF effusions (p < 0.005 each), and in CA vs. CON plasma (p < 0.05). MMP-2, TIMP-1, and TIMP-2 accumulate in the pleural compartment in CA and CHF, probably reflecting an unspecific pleural reaction. MMP-1 and MMP-8 are increased in cellular rich CA pleural effusions only. The determination of MMP-9/MMP-2 ratios in pleural fluid may contribute to differentiate CHF from CA effusions.

The diagnosis of the cause of pleural effusions caused by cardiovascular diseases such as congestive heart failure (CHF) and acute pulmonary embolism is sometimes difficult. The purpose of the present study was to evaluate the utility of pleural fluid levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) in differentiating pleural effusions due to CHF, pulmonary embolism and post-coronary artery bypass graft (CABG) surgery. The levels of pleural fluid NT-proBNP were measured by ELISA in a total of 40 patients: 10 with CHF, 10 with pulmonary embolism, 10 post-CABG and 10 with carcinoma. The median level of NT-proBNP in the pleural fluid of patients with CHF was 5390 pg/mL (25th to 75th percentiles, 4566 to 8158 pg/mL), which was significantly higher than that in patients with post-CABG effusions (424 pg/mL, 352 to 873), with pulmonary embolism (311 pg/mL, 212 to 1159), or with carcinoma (302 pg/mL, 208 to 626) (P < 0.001, CHF group vs all other groups). In receiver-operating curve analysis, an NT-proBNP level of >or=2220 pg/mL demonstrated a sensitivity of 100% and a specificity of 96.7% for the identification of CHF. Measurement of the NT-proBNP level in pleural fluid is accurate in diagnosing the etiology of the effusion as CHF. Pleural fluid levels above 2220 pg/mL are essentially diagnostic that the pleural effusion is due to CHF.

Background Postoperative pleural drainage markedly influences the length of postoperative stay and financial costs of medical care. The aim of this study is to retrospectively investigate potentially predisposing factors related to pleural drainage after curative thoracic surgery and to explore the impact of mediastinal micro-vessels clipping on pleural drainage control after lymph node dissection. Methods From February 2012 to November 2013, 322 consecutive cases of operable non-small cell lung cancers (NSCLC) undergoing lobectomy and mediastinal lymph node dissection with or without application of clipping were collected. Total and daily postoperative pleural drainage were recorded. Propensity score matching (1:2) was applied to balance variables potentially impacting pleural drainage between group clip and group control. Analyses were performed to compare drainage volume, duration of chest tube and postoperative hospital stay between the two groups. Variables linked with pleural drainage in whole cohort were assessed using multivariable logistic regression analysis. Results Propensity score matching resulted in 197 patients (matched cohort). Baseline patient characteristics were matched between two groups. Group clip showed less cumulative drainage volume (P=0.020), shorter duration of chest tube (P=0.031) and postoperative hospital stay (P=0.022) compared with group control. Risk factors significantly associated with high-output drainage in multivariable logistic regression analysis were being male, age >60 years, bilobectomy/sleeve lobectomy, pleural adhesion, the application of clip applier, duration of operation ≥220 minutes and chylothorax (P<0.05). Conclusions This study suggests that mediastinal micro-vessels clipping during lymph node dissection may reduce postoperative pleural drainage and thus shorten hospital stay. PMID:27076936

Pleural effusion is a frequent finding in patients with acute respiratory distress syndrome. To assess the effects of pleural effusion in patients with acute lung injury on lung volume, respiratory mechanics, gas exchange, lung recruitability, and response to positive end-expiratory pressure. A total of 129 acute lung injury or acute respiratory distress syndrome patients, 68 analyzed retrospectively and 61 prospectively, studied at two University Hospitals. Whole-lung CT was performed during two breath-holding pressures (5 and 45 cm H2O). Two levels of positive end-expiratory pressure (5 and 15 cm H2O) were randomly applied. Pleural effusion volume was determined on each CT scan section; respiratory system mechanics, gas exchange, and hemodynamics were measured at 5 and 15 cm H2O positive end-expiratory pressure. In 60 patients, elastances of lung and chest wall were computed, and lung and chest wall displacements were estimated. Patients were divided into higher and lower pleural effusion groups according to the median value (287 mL). Patients with higher pleural effusion were older (62±16 yr vs. 54±17 yr, p<0.01) with a lower minute ventilation (8.8±2.2 L/min vs. 10.1±2.9 L/min, p<0.01) and respiratory rate (16±5 bpm vs. 19±6 bpm, p<0.01) than those with lower pleural effusion. Both at 5 and 15 cm H2O of positive end-expiratory pressure PaO2/FIO2, respiratory system elastance, lung weight, normally aerated tissue, collapsed tissue, and lung and chest wall elastances were similar between the two groups. The thoracic cage expansion (405±172 mL vs. 80±87 mL, p<0.0001, for higher pleural effusion group vs. lower pleural effusion group) was greater than the estimated lung compression (178±124 mL vs. 23±29 mL, p<0.0001 for higher pleural effusion group vs. lower pleural effusion group, respectively). Pleural effusion in acute lung injury or acute respiratory distress syndrome patients is of modest entity and leads to a greater chest wall expansion than lung reduction, without affecting gas exchange or respiratory mechanics.

Cases of metastatic anal carcinoma managed with a combination of systemic chemotherapy and local therapies to both solitary sites of metastases and the primary site have been reported in the literature. We present a case of a 55-year-old male with metastatic anal squamous cell carcinoma to the liver treated with induction chemotherapy with cisplatin (CDDP) and 5-fluorouracil (5FU) followed by liver resection and radiation to the anal primary with concurrent 5FU and mitomycin. This approach resulted in control of disease without evidence of recurrence, and no increased toxicities now 19 months from initial diagnosis to time of reporting. This novel approach resulted in a good treatment response as documented by imaging and symptom improvement and a long disease free interval.

We review the literature on the use of point-of-care ultrasound to evaluate and manage pleural effusions. Point-of-care ultrasound is more sensitive than physical exam and chest radiography to detect and characterize pleural fluid, and avoids many negative aspects of computerized tomography (CT). Additionally, point-of-care ultrasound can be used to assess pleural fluid volume and character, revealing possible underlying pathologies and guiding management. Thoracentesis performed with ultrasound guidance has lower risk of pneumothorax and bleeding complications. Future research should focus on the clinical-effectiveness of point-of-care ultrasound in the routine management of pleural effusions and how new technologies may expand its clinical utility.

Pleural effusion after hepatectomy is associated with significant morbidity and prolonged hospital stays. Several studies have addressed the risk factors for postoperative pleural effusion. However, there are no researches concerning the role of the initial 12-h operative fluid volume. The aim of this study was to evaluate whether the initial 12-h operative fluid volume during liver resection is an independent risk factor for pleural effusion after hepatectomy. In this study, we retrospectively analyzed clinical data of 470 patients consecutively undergoing elective hepatectomy between January 2011 and December 2012. We prospectively collected and retrospectively analyzed baseline and clinical data, including preoperative, intraoperative, and postoperative variables. Univariate and multivariate analyses were carried out to identify whether the initial 12-h operative fluid volume was an independent risk factor for pleural effusion after hepatectomy. The multivariate analysis identified 2 independent risk factors for pleural effusion: operative time [odds ratio (OR)=10.2] and initial 12-h operative fluid volume (OR=1.0003). Threshold effect analyses revealed that the initial 12 h operative fluid volume was positively correlated with the incidence of pleural effusion when the initial 12-h operative fluid volume exceeded 4636 mL. We conclude that the initial 12-h operative fluid volume during liver resection and operative time are independent risk factors for pleural effusion after hepatectomy. Perioperative intravenous fluids should be restricted properly.

Pleural effusion is associated with multiple benign and malignant conditions. Currently no biomarkers differentiate malignant pleural effusion (MPE) and benign pleural effusion (BPE) sensitively and specifically. The present study identified a novel combination of biomarkers in pleural effusion for differentiating MPE from BPE by enrolling 75 patients, 34 with BPE and 41 with MPE. The levels of lactate dehydrogenase, glucose, protein, and total cell, neutrophil, monocyte and lymphocyte counts in the pleural effusion were measured. The concentrations of interleukin (IL)-1β, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, tumor necrosis factor-α, interferon γ, transforming growth factor-β1, colony stimulating factor 2, monocyte chemoattractant protein-1 and vascular endothelial growth factor (VEGF) were detected using cytometric bead arrays. Protein and VEGF levels differed significantly between patients with BPE and those with MPE. The optimal cutoff value of VEGF and protein was 214 pg/ml and 3.35 g/dl respectively, according to the receiver operating characteristic curve. A combination of VEGF >214 pg/ml and protein >3.35 g/dl in pleural effusion presented a sensitivity of 92.6% and an accuracy of 78.6% for MPE, but was not associated with a decreased survival rate. These results suggested that this novel combination strategy may provide useful biomarkers for predicting MPE and facilitating early diagnosis.

Malignant pleural mesothelioma in a 17-year old boy: A case report and literature review.

Malignant pleural mesothelioma is a rare, invasive and often fatal neoplasm that develops in the thin layer of tissue surrounding the lungs known as the pleura. Although rare, mesotheliomas do occur in the young; their characteristics are distinct from those of older patients. This is a case report of a 17-year-old boy who had moderate dyspnea, cough, right-sided pleuritic chest pain, fever, headache and no weight loss. Physical examination showed a right pleural effusion and chest roentgenograms revealed a homogenous opacity on lower right hemithorax. Biochemical analysis of pleural fluid showed hemorrhagic/turbid effusion compatible with exudate. It was initially treated as an empyema. The pleural fluid culture was negative. Adenosine deaminase level was 34.3 U/L (admission) and 19.02 U/L (two weeks after). Pleural fluid smear and culture for Mtb were negative. During the open pleural biopsy, thickened pleura and multiple pale yellow nodules in the lung were observed. The histopathological report was compatible with malignant pleural mesothelioma. With this diagnosis, a chemotherapy regimen with cisplatin was initiated. After two cycles, the patient had no clinical and radiological improvement. The patient is currently under regular follow up. MPM is rare in young adults and its clinical presentation makes it different from mesothelioma in elderly patients, so it will be necessary to identify the new risk factors that can identify these patients.

Unexpandable lung.

PubMed

Pereyra, Marco F; Ferreiro, Lucía; Valdés, Luis

2013-02-01

Unexpandable lung is a mechanical complication by which the lung does not expand to the chest wall, impeding a normal apposition between the two pleural layers. The main mechanism involved is the restriction of the visceral pleura due to the formation of a fibrous layer along this pleural membrane. This happens because of the presence of an active pleural disease (lung entrapment), which can be resolved if proper therapeutic measures are taken, or a remote disease (trapped lung), in which an irreversible fibrous pleural layer has been formed. The clinical suspicion arises with the presence of post-thoracocentesis hydropneumothorax or a pleural effusion that cannot be drained due to the appearance of thoracic pain. The diagnosis is based on the analysis of the pleural liquid, the determination of pleural pressures as we drain the effusion and on air-contrast chest CT. As both represent the continuity of one same process, the results will depend on the time at which these procedures are done. If, when given a lung that is becoming entrapped, the necessary therapeutic measures are not taken, the final result will be a trapped lung. In this instance, most patients are asymptomatic or have mild exertional dyspnea and therefore they do not require treatment. Nevertheless, in cases of incapacitating dyspnea, it may be necessary to use pleural decortication in order to resolve the symptoms. Copyright © 2012 SEPAR. Published by Elsevier Espana.

Cats with pleural effusion represent common emergencies in small animal practice. The aim of this prospective study was to investigate the diagnostic ability of a point-of-care ELISA (POC-ELISA) for the measurement of N-terminal pro B-type natriuretic peptide (NT-proBNP) to differentiate cardiac from non-cardiac disease in cats with pleural effusion. The sample material for use of this rapid test was either plasma or diluted pleural effusion. Twenty cats with moderate to severe pleural effusion were prospectively recruited. The cats were grouped into two groups, with or without congestive heart failure (CHF; N-CHF), after complete work-up. Blood and effusion were collected in EDTA tubes. Plasma and pleural effusion supernatants were transferred into stabilizer tubes and frozen. POC-ELISA for NT-proBNP was performed with plasma and diluted effusion (1:1). Quantitative NT-proBNP measurement was performed in plasma and diluted and undiluted effusions. Six cats were assigned to the CHF group. Of the 14 cats in the N-CHF group, 6 had concurrent cardiac abnormalities that were not responsible for the effusion. For the detection of CHF, the test displayed respective sensitivities and specificities of 100% and 79% in plasma and 100% and 86% in diluted pleural fluid. Receiver operating characteristic (ROC) analysis for quantitative NT-proBNP measurement of plasma and diluted and undiluted pleural effusions displayed areas under the curve of 0.98, sensitivities of 100% and specificities of 86%. The optimum cut-off was calculated at 399 pmol/l in plasma and 229 pmol/l in the diluted effusion and 467 pmol/l in the undiluted effusion. POC-ELISA for NT-proBNP in both plasma and diluted pleural effusion was suitable to differentiate cardiac from non-cardiac causes of feline pleural effusion. According to our results, use of pleural effusion is feasible, but dilution of the effusion before measurement seems to improve specificity.

Translocation pathways for inhaled asbestos fibers

PubMed Central

Miserocchi, G; Sancini, G; Mantegazza, F; Chiappino, Gerolamo

2008-01-01

We discuss the translocation of inhaled asbestos fibers based on pulmonary and pleuro-pulmonary interstitial fluid dynamics. Fibers can pass the alveolar barrier and reach the lung interstitium via the paracellular route down a mass water flow due to combined osmotic (active Na+ absorption) and hydraulic (interstitial pressure is subatmospheric) pressure gradient. Fibers can be dragged from the lung interstitium by pulmonary lymph flow (primary translocation) wherefrom they can reach the blood stream and subsequently distribute to the whole body (secondary translocation). Primary translocation across the visceral pleura and towards pulmonary capillaries may also occur if the asbestos-induced lung inflammation increases pulmonary interstitial pressure so as to reverse the trans-mesothelial and trans-endothelial pressure gradients. Secondary translocation to the pleural space may occur via the physiological route of pleural fluid formation across the parietal pleura; fibers accumulation in parietal pleura stomata (black spots) reflects the role of parietal lymphatics in draining pleural fluid. Asbestos fibers are found in all organs of subjects either occupationally exposed or not exposed to asbestos. Fibers concentration correlates with specific conditions of interstitial fluid dynamics, in line with the notion that in all organs microvascular filtration occurs from capillaries to the extravascular spaces. Concentration is high in the kidney (reflecting high perfusion pressure and flow) and in the liver (reflecting high microvascular permeability) while it is relatively low in the brain (due to low permeability of blood-brain barrier). Ultrafine fibers (length < 5 μm, diameter < 0.25 μm) can travel larger distances due to low steric hindrance (in mesothelioma about 90% of fibers are ultrafine). Fibers translocation is a slow process developing over decades of life: it is aided by high biopersistence, by inflammation-induced increase in permeability, by low steric hindrance and by fibers motion pattern at low Reynolds numbers; it is hindered by fibrosis that increases interstitial flow resistances.

INTRODUCTION The aim of this study was to investigate the prevalence of risk factors for primary squamous cell carcinoma (SCC) of the bladder. MATERIALS A total of 90 cases of primary SCC of the bladder were identified through multicentre analysis. Patient demographics, stage and grade of cancer at presentation, management and outcomes were recorded. The presence of known risk factors (catheter use, neuropathic bladder, smoking history, recurrent urinary tract infection and bladder stones) was also documented. RESULTS Over half of the patients had at least one identifiable risk factor for the development of primary bladder SCC: 13.9% of patients had a history of catheter use (clean intermittent self-catheterisation [CISC] in 11.1%), 10.0% of patients had a neuropathic bladder, 27.8% were smokers or ex-smokers and 20.0% had a documented history of recurrent urinary tract infection. Statistical analysis of the results showed no association between risk factors and grade of tumour at presentation. CONCLUSIONS These data further support the association between primary bladder SCC and several of the well documented risk factors for its development. Chronic use of CISC may confer a greater risk for development of SCC than thought previously. Further evidence of the role of CISC in primary SCC is required to justify routine screening and to determine exactly when surveillance of the bladder should begin for this group of patients.

To demonstrate the efficacy, safety, and appropriate mode of instillation of talc for sclerosis in treatment of malignant pleural effusions (MPEs). A prospective, randomized trial was designed to compare thoracoscopy with talc insufflation (TTI) to thoracostomy and talc slurry (TS) for patients with documented MPE. The primary end point was 30-day freedom from radiographic MPE recurrence among surviving patients whose lungs initially re-expanded > 90%. Morbidity, mortality, and quality of life were also assessed. Of 501 patients registered, those eligible were randomized to TTI (n = 242) or TS (n = 240). Patient demographics and primary malignancies were similar between study arms. Overall, there was no difference between study arms in the percentage of patients with successful 30-day outcomes (TTI, 78%; TS, 71%). However, the subgroup of patients with primary lung or breast cancer had higher success with TTI than with TS (82% vs 67%). Common morbidity included fever, dyspnea, and pain. Treatment-related mortality occurred in nine TTI patients and seven TS patients. Respiratory complications were more common following TTI than TS (14% vs 6%). Respiratory failure was observed in 4% of TS patients and 8% of TTI patients, accounting for five toxic deaths and six toxic deaths, respectively. Quality-of-life measurement demonstrated less fatigue with TTI than TS. Patient ratings of comfort and safety were also higher for TTI, but there were no differences on perceived value or convenience of the procedures. Both methods of talc delivery are similar in efficacy; TTI may be better for patients with either a lung or breast primary. The etiology and incidence of respiratory complications from talc need further exploration.

Elevated concentrations of plasminogen activator inhibitor–1 (PAI-1) are associated with pleural injury, but its effects on pleural organization remain unclear. A method of adenovirus-mediated delivery of genes of interest (expressed under a cytomegalovirus promoter) to rabbit pleura was developed and used with lacZ and human (h) PAI-1. Histology, β-galactosidase staining, Western blotting, enzymatic and immunohistochemical analyses of pleural fluids (PFs), lavages, and pleural mesothelial cells were used to evaluate the efficiency and effects of transduction. Transduction was selective and limited to the pleural mesothelial monolayer. The intrapleural expression of both genes was transient, with their peak expression at 4 to 5 days. On Day 5, hPAI-1 (40–80 and 200–400 nM of active and total hPAI-1 in lavages, respectively) caused no overt pleural injury, effusions, or fibrosis. The adenovirus-mediated delivery of hPAI-1 with subsequent tetracycline-induced pleural injury resulted in a significant exacerbation of the pleural fibrosis observed on Day 5 (P = 0.029 and P = 0.021 versus vehicle and adenoviral control samples, respectively). Intrapleural fibrinolytic therapy (IPFT) with plasminogen activators was effective in both animals overexpressing hPAI-1 and control animals with tetracycline injury alone. An increase in intrapleural active PAI-1 (from 10–15 nM in control animals to 20–40 nM in hPAI-1–overexpressing animals) resulted in the increased formation of PAI-1/plasminogen activator complexes in vivo. The decrease in intrapleural plasminogen-activating activity observed at 10 to 40 minutes after IPFT correlates linearly with the initial concentration of active PAI-1. Therefore, active PAI-1 in PFs affects the outcome of IPFT, and may be both a biomarker of pleural injury and a molecular target for its treatment. PMID:23002099

The aim of the present study was to evaluate the therapeutic effects and adverse reactions of Tarceva treatment for malignant pleural effusion (MPE) caused by metastatic lung adenocarcinomas. One hundred and twenty-eight patients who failed first-line chemotherapy drug treatment were divided into a mutation and a non-mutation group according to the presence or absence of epidermal growth factor receptor (EGFR) mutations. Each patient received closed drainage combined with simple negative pressure suction after thoracoscopic talc poudrage pleurodesis and oral Tarceva treatment. Short-term and long-term clinical therapeutic effects of Tarceva were evaluated. The EGFR mutation rate in pleural metastatic tissues of lung adenocarcinoma acquired through video-assisted thoracoscopic surgery was higher compared to that in surgical resection specimens, plasma specimens and pleural effusion specimens compared to previously reported results. There were significant statistical differences in the average extubation time (p<0.01), drainage volume of pleural effusion (p<0.05), Karnofsky score and formation of encapsulated pleural effusion 4 weeks after surgery (p<0.05) between these two groups. The number of patients with mild pleural hypertrophy in the mutation group was significantly higher compared to the non-mutation group (p<0.01), while the number of patients with severe pleural hypertrophy was significantly reduced (p<0.05). There was significant statistical discrepancy between these two groups in terms of improvement of peripheral blood carcinoembryonic antigen and tissue polypeptide antigen after 4 weeks of therapy. The complete remission rate and the efficacy rate were higher in the mutation group compared to that in the non-mutation group (p<0.05). There was a longer overall survival time after Tarceva treatment in patients with EGFR mutations than those without EGFR mutation. EGFR mutations predict a favorable outcome for malignant pleural effusion of lung adenocarcinoma with Tarceva therapy. Detection of EGFR mutations may determine the responsiveness of malignant pleural effusion to Tarceva treatment.

The pleural surfaces of the chest wall and lung slide against each other, lubricated by pleural fluid. During sliding motion of soft tissues, shear induced hydrodynamic pressure deforms the surfaces, promoting uniformity of the fluid layer thickness, thereby reducing friction. To assess pleural deformability at length scales comparable to pleural fluid thickness, we measured the modulus of the parietal pleura of rat chest wall using atomic force microscopy (AFM) to indent the pleural surface with spheres (radius 2.5 µm and 5 µm). The pleura exhibited two distinct indentation responses depending on location, reflecting either homogeneous or significantly heterogeneous tissue properties. We found an elastic modulus of 0.38–0.95 kPa, lower than the values measured using flat-ended cylinders > 100 µm radii (Gouldstone et al., 2003, Journal of Applied Physiology 95, 2345–2349). Interestingly, the pleura exhibited a three-fold higher modulus when probed using 2.5 µm vs. 5 µm spherical tips at the same normalized depth, confirming depth dependent inhomogeneous elastic properties. The observed softness of the pleura supports the hypothesis that unevenness of the pleural surface on this scale is smoothed by local hydrodynamic pressure. PMID:21820660

Intraoperative analysis of sentinel lymph nodes would enhance the care of early-stage oral squamous cell carcinoma (OSCC). We determined the frequency and extent of cytokeratin 19 (CK19) expression in OSCC primary tumours and surrounding tissues to explore the feasibility of a "clinic-ready" intraoperative diagnostic test (one step nucleic acid amplification-OSNA, sysmex). Two cohorts were assembled: cohort 1, OSCC with stage and site that closely match cases suitable for sentinel lymph node biopsy (SLNB); cohort 2, HNSCC with sufficient fresh tumour tissue available for the OSNA assay (>50 mg). CK19 assays included qRT-PCR, RNA in situ hybridisation (ISH), and immunohistochemistry (IHC), as well as OSNA. CK19 mRNA expression was detected with variable sensitivity, depending on method, in 60-80% of primary OSCC tumours, while protein expression was observed in only 50% of tumours. Discordance between different techniques indicated that OSNA was more sensitive than qRT-PCR or RNA-ISH, which in turn were more sensitive than IHC. OSNA results showed CK19 expression in 80% of primary cases, so if used for diagnosis of lymph node metastasis would lead to a false-negative result in 20% of patients with cervical lymph node metastases. OSNA in its current form is not suitable for use in OSCC SLNB due to inadequate expression of the CK19 target in all case. However, the same assay technology would likely be very promising if applied using a more ubiquitous squamous epithelial target.

The purpose of this study was to assess whether a positron emission tomography (PET)-directed policy remains appropriate for managing neck nodes (N3; >6 cm) in head and neck squamous cell carcinoma (HNSCC). All patients with N3 (>6 cm) HNSCC treated with definitive chemoradiotherapy (CRT) at our institution between 2005 and 2012 were included in the analysis. Patients underwent PET assessment before and 12 weeks after CRT. Neck dissections were performed for PET-avid residual nodal abnormalities after complete response at the primary site. Rate of isolated nodal failure (INF) was the primary outcome. Median follow-up from diagnosis for 33 patients was 30 months (range, 6-76 months). INF occurred in 2 patients (6%) with neck dissections performed in 4 cases (12%). First failure was predominantly distant metastatic (10; 30%). The rate of INF remains low when following a PET-directed neck management policy after definitive CRT for N3 (>6 cm) HNSCC. Copyright © 2013 Wiley Periodicals, Inc.

Long-term cetuximab treatment can lead to acquired resistance, and tumor progression and/or new lesions often occur. The present report describes a case of lower gingival squamous cell carcinoma with brain metastasis during long-term cetuximab treatment in a 60-year-old man, including findings of an immunohistochemical study. The resected primary tumors, biopsy of the lung metastasis before administration of cetuximab, and brain metastasis specimens mediated by cetuximab were immunohistochemically examined. Histologically, the metastatic brain lesion showed hyperkeratinizing tumor cells with deeply stained irregular nuclei with necrotizing tumor cells, and a decrease in cell density was exhibited in part of the tumor nest. Moreover, the brain lesion was less malignant compared with the primary tumor and metastatic lung lesions. Immunohistochemically, the metastatic brain lesions showed low expression of epidermal growth factor receptor (EGFR) and high expression of N-cadherin compared with the primary tumor and metastatic lung lesions. These results suggest that acquired resistance to cetuximab may be associated with low EGFR expression and increased epithelial-to-mesenchymal transition potential.

Background and Aims Amplification of the fibroblast growth factor receptor 1 (FGFR1) is believed to predict response to multi-kinase inhibitors targeting FGFR1. Esophageal cancer is an aggressive disease, for which novel targeted therapies are highly warranted. Methods This study was designed to investigate the prevalence and clinical significance of FGFR1 amplification in a tissue microarray containing 346 adenocarcinomas and 254 squamous cell carcinomas of the esophagus, using dual-labeling fluorescence in situ hybridization (FISH) analysis. Results FGFR1 amplification, defined as a ratio of FGFR1:centromere 8 copy numbers ≥ 2.0, was more frequently seen in squamous cell carcinoma (8.9% of 202 interpretable cases) than in adenocarcinoma (1.6% of 308; p<0.0001). There was no association between FGFR1 amplification and tumor phenotype or clinical outcome. To study potential heterogeneity of FGFR1 amplification, all available tumor blocks from 23 FGFR1 amplified tumors were analyzed on conventional large sections. This analysis revealed complete homogeneity of FGFR1 amplification in 20 (86.9%) primary tumors and in all available lymph node metastases. Remarkably, FGFR1 amplification was also seen in dysplasia adjacent to tumor in 6 of 9 patients with FGFR1 amplified primary cancers. Conclusions In conclusion, FGFR1 amplification occurs in a relevant subgroup of carcinomas of the esophagus and may play a particular role for development of squamous cell cancers. The high homogeneity of FGFR1 amplification suggests that patients with FGFR1 amplified esophageal cancers may particularly benefit from anti-FGFR1 therapies and prompt for clinical studies in this tumor type.

Several endoscopic dilation techniques have been reported for treatment of anastomotic-stenosis of esophageal cancer, but the high incidence of dysphagia has remained unchanged. The aim of this study was to compare the effect of Argon Plasma Coagulation (APC) combined with Savary Bougienage (SB) compared to APC alone or SB alone for anastomotic-stenosis after radical operation for squamous cell carcinoma of the esophagus. Patients with anastomotic-stenosis that was diagnosed for the first time following esophageal squamous cell carcinoma resection surgery were randomly assigned to undergo APC combined with SB, APC alone, or SB alone. Primary endpoints were the dysphagia-free survival (DFS defined as the time from first dilatation of effectively relieved dysphagia to dysphagia relapse expressed in days) after 6 months of follow up. A total of 90 patients from the Cancer Institute, First Affiliated Hospital of Henan University of Science and Technology were entered into the study (APC group, n = 30, SB group, n = 30, combination group [APC combined with SB], n = 30). Primary endpoints: 6 months after treatment, DFS of combination group (115.63 days; 95% CI, 105.31-125.95) was significantly longer than the APC alone group (39.53 days; 95% CI, 35.95-43.11, p = 0.000) and the SB alone group (16.93 days; 95% CI, 15.01-18.84, p = 0.000). No severe complications occurred within the three treatment groups. APC combined with SB was a safe and well-tolerated method for relieving dysphagia of esophageal squamous cell cancer patients with anastomotic-stenosis.

Painful bladder syndrome/interstitial cystitis (PBS/IC) is a severely debilitating condition. Its cause is poorly understood; therapy is symptomatic and often unsuccessful. To study urothelial involvement, we characterized the keratin phenotype of bladder urothelium in 18 patients with PBS/IC using a panel of 11 keratin antibodies recognizing simple keratins found in columnar epithelia (keratins 7, 8, 18, and 20) and keratins associated with basal cell compartments of squamous epithelia (keratins 5, 13, 14, and 17). We also tested 2 antibodies recognizing more than 1 keratin also directed against basal cell compartments of squamous epithelia (D5/16 B4 and 34betaE12). Bladder urothelium in PBS/IC showed distinct differences in the profiles of keratins 7, 8, 14, 17, 18, and 20 compared with literature reports for normal bladder urothelium. These were characterized by a shift from the normal bladder urothelial keratin phenotype to a more squamous keratin profile, despite the lack of morphologic evidence of squamous epithelial differentiation and a loss of compartmentalization of keratin expression. The severity of these changes varied between biopsy specimens. Whether these changes are primary or secondary to another underlying condition remains to be determined.

Today, standard treatment of pleural effusion is ultrasound guided insertion of a pleural pigtail catheter. This procedure is known to have a low complication rate, but complications as pneumothorax, haemorrhage and infection are occurring. The most frequent complications are seen at the time of insertion. We present a case of a 68-year-old woman in the intensive care unit with normal coagulation status who after an uneventful removal of a pleural pigtail catheter developed a tension haemothorax requiring acute evacuation.

An increasing incidence of parapneumonic effusion and pleural empyema (PPE/PE) has been reported in recent studies. As only few data on etiology of PPE/PE in Central Europe have been reported, we undertook a study on the etiology of PPE/PE in children, using both standard culture and molecular techniques. This prospective study was conducted between June 2011 and December 2013. Consecutive children with PPE/PE complicating community acquired pneumonia, who required diagnostic/therapeutic thoracentesis were included. Blood and pleural fluid samples for microbiological cultures were collected. Molecular methods were applied to identify Streptococcus pneumonia, Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, Mycoplasma pneumoniae, Chlamydophila pneumoniae, and respiratory viruses in pleural fluid. The study group included 64 children, median age 4 (1-15). Seven of 64 (10.9%) blood cultures and 11 of 64 (17.2%) pleural fluid cultures revealed bacterial growth. The most common bacteria detected was S. pneumoniae (13 blood and pleural fluid samples from 11/64 (17.2%) children). DNA sequences of typical bacteria were found in 29/64 (45.3%) pleural fluid samples. S. pneumoniae was identified in 90% of these samples. The most common serotypes were: serotype 6B in 9/26 (36.6%), 19A in 6/26 (23%), serotype 3 in 3/26 (11.5%), 6A and 23F (both in 2/26 i.e. 7.7%) patients. Molecular methods identified atypical bacteria in 8/58 (13.8%) and respiratory viruses in 12/58 (20.7%) pleural fluid samples. S. pneumoniae, in particular serotype 6B and 19A, is the most common etiologic agent of PPE/PE in Polish children. The use of PCR significantly improves pathogen identification in pleural fluid.

To evaluate whether main tumor resection improves survival compared with pleural biopsy alone in patients with lung adenocarcinoma with intraoperatively diagnosed pleural seeding. Forty-three patients with lung adenocarcinoma with pleural seeding diagnosed unexpectedly during surgery performed between January 2006 and December 2014 were included in this retrospective study using a prospectively collected lung cancer database. Each surgeon decided whether to perform main tumor resection or pleural biopsy alone. Main tumor and visible pleural nodule resection was performed in 30 patients (tumor resection group). The remaining 13 patients underwent pleural nodule biopsy alone (open-close group). The clinical T stage was higher in the open-close group than in the tumor resection group (P = .02). The tumor resection group had longer operative times compared with the open-close group (mean, 141.8 vs 80.3 minutes). There were no other statistically significant differences in perioperative parameters. The surgical method was the sole statistically significant prognostic factor. Patients in the tumor resection group had better progression-free survival (3-year survival: 44.5% vs 0%; P = .009) and overall survival (3-year survival: 82.9% vs 38.5%; P = .013) than did the open-close group. There was no significant survival difference between sublobar resection and lobectomy for the main tumor resection. Our study demonstrated improved progression-free and overall survival after main tumor and visible pleural nodule resection in patients with lung adenocarcinoma with intraoperatively diagnosed pleural seeding. Further randomized trials are needed to define the role of main tumor resection in these patients. Copyright © 2017 The American Association for Thoracic Surgery. Published by Elsevier Inc.

Despite recent advances in methods for culturing Mycobacterium tuberculosis (MTB), the diagnostic yield of tuberculous pleural effusion (TBPE) remains unsatisfactory. However, unlike repeated sputum cultures of pulmonary tuberculosis, little is known about the role of repeated pleural cultures. We examined whether repeated pleural cultures are associated with increased MTB yield from TBPE. A multicenter, retrospective cohort study was performed from January 2012 to December 2015 in South Korea. Patients were categorized into two groups: single- or repeated-culture groups. The diagnostic yield of MTB and clinical, radiological, and pleural fluid characteristics were evaluated. Among the 329 patients with TBPE, 77 (23.4%) had repeated cultures and 252 (76.5%) had a single culture. Pleural culture was performed twice in all 77 patients in the repeated-culture group at a 1-day interval (inter-quartile range, 1.0-2.0). In the repeated-culture group, the yield of MTB from the first culture was 31.2%, which was similar to that in the single-culture group (31.2% vs. 29.8%, P = 0.887). However, the yield of MTB from the second culture (10/77, 13.0%) was more than that from the first. These results may be attributable to the insufficient immune clearance for MTB invasion into the pleural space between the first and second cultures. Over time, the yield of the second cultures decreased from 17.4% to 6.7% and then 6.3%. Finally, the overall yield of MTB in the repeated- and single-culture groups was 44.2% and 29.8% respectively (P < 0.001). The results showed that repeated pleural cultures increased MTB yield from TBPE in human immunodeficiency virus-negative individuals. Furthermore, repeated cultures may increase yield when carried out for two consecutive days.

Transforming growth factor β (TGF-β) is a cytokine which has been shown to suppress the antimycobacterial immune responses of humans and experimental animals. In this study, the contributions of TGF-β to cytokine production in vivo were investigated by using the established guinea pig model of tuberculous pleurisy. Mycobacterium bovis BCG-vaccinated guinea pigs were injected intrapleurally with heat-killed virulent Mycobacterium tuberculosis. Eight days following induction of an antigen-specific pleural effusion, guinea pigs were injected intrapleurally with anti-TGF-β1 or isotype control antibody. The following day, pleural exudates were removed, and the fluid volume and characteristics of the infiltrating cells were determined. Pleural fluid was analyzed for total interferon (IFN) and tumor necrosis factor (TNF) protein levels by using appropriate bioassays. RNA from pleural effusion cells was examined to determine TGF-β1, TNF-α, IFN-γ, and interleukin-8 mRNA levels by using real-time PCR. Proliferative responses of pleural effusion lymphocytes were examined in response to concanavalin A and purified protein derivative (PPD) in vitro. Treatment with anti-TGF-β1 resulted in decreased pleural fluid volume and decreased cell numbers in the pleural space along with an increased percentage of lymphocytes and a decreased percentage of neutrophils. The bioactive TNF protein levels in pleural fluid were increased in guinea pigs treated with anti-TGF-β1, while the bioactive IFN protein concentrations were not altered. Expression of TGF-β1 and TNF-α mRNA was significantly increased following TGF-β1 neutralization. Finally, PPD-induced proliferative responses of pleural cells from anti-TGF-β1-treated animals were significantly enhanced. Thus, TGF-β1 may be involved in the resolution of this local, mycobacterial antigen-specific inflammatory response. PMID:14977939

Tuberculous Pleural Effusion

When a patient presents with new pleural effusion, the diagnosis of tuberculous (TB) pleuritis should be considered. The patient is at risk for developing pulmonary or extrapulmonary TB if the diagnosis is not made. Between 3% and 25% of patients with TB will have TB pleuritis. The incidence of TB pleuritis is higher in patients who are human immunodeficiency virus (HIV)-positive. Pleural fluid is an exudate that usually has a predominance of lymphocytes. The easiest way to diagnose TB pleuritis in a patient with lymphocytic pleural effusion is to demonstrate a pleural fluid adenosine deaminase level above 40 IU/L. The treatment for TB pleuritis is the same as that for pulmonary TB. Tuberculous empyema is a rare occurrence, and the treatment is difficult. PMID:29404070

A 57-year-old diabetic and hypertensive man presented with a short history of fever, dry cough and right side chest pain. A chest radiograph showed right pleural based homogenous shadow in middle and lower zones with obliteration of right costo-phrenic angle suggestive of right side effusion. Aspiration of pleural fluid revealed frank pus for which inter-costal tube drainage was performed. Due to persistence of empyema, the patient was subjected to thoracoscopy. Thoracoscopy showed multiloculated empyema. Thoracoscopic pleural biopsy and fluid showed septate fungal hyphae. Thoracotomy and parietal pleurectomy, with resection of part of right lower lobe, was carried out. Pleural fluid, pleural and lung tissue culture grew Aspergillus fumigatus. The patient showed good recovery with voriconazole after thoracotomy. PMID:20539768

Tight junction physiology of pleural mesothelium

PubMed Central

Markov, Alexander G.; Amasheh, Salah

2014-01-01

Pleura consists of visceral and parietal cell layers, producing a fluid, which is necessary for lubrication of the pleural space. Function of both mesothelial cell layers is necessary for the regulation of a constant pleural fluid volume and composition to facilitate lung movement during breathing. Recent studies have demonstrated that pleural mesothelial cells show a distinct expression pattern of tight junction proteins which are known to ubiquitously determine paracellular permeability. Most tight junction proteins provide a sealing function to epithelia, but some have been shown to have a paracellular channel function or ambiguous properties. Here we provide an in-depth review of the current knowledge concerning specific functional contribution of these proteins determining transport and barrier function of pleural mesothelium.

Thymoma is the most common benign neoplasm of the anterior mediastinum presenting often an agressive behaviour typical for the malignants tumors. The rate of invasive thymoma recurrency is relatively high. We present the case of a 55-year old man with a recurrent invasive thymoma with a pleural dissemination, detected on CT-imaging 2 years following his primary surgery. Since the first pre-operative imaging studies showed no invasion of the adjacent organs and a thymoma was suspected, a surgical resection was decided as a first line treatment. Per-operatively a number of adjacent structures were invaded and despite a macroscopical RO resection, the margins were microscopically positive. An invasive thymoma, WHO classification B3, Masaoka stage IVb was diagnosed and the patient received adjuvant radiotherapy. We highlight the role of multimodality treatement and disscus the potential of surgical, radiotherapeutical and systemic therapy in stage IV thymoma as well as in recurrent disease.

Malignant pleural effusion is a frequent complication in many types of tumors, and its presence indicates short expected survival. This review updates the current knowledge about diagnosis and management of malignant pleural effusion. In recent years, progress has been made in diagnosis through the use of new pathologic and radiologic approaches, such as the introduction of positron emission tomography-computed tomography, immunohistochemical marker combinations, and genetic studies to identify malignant cells. Treatment is always palliative. New promising drugs have been tested, but, awaiting randomized studies, talc pleurodesis is still the treatment of choice, although doubts remain about its safety. A long-term indwelling pleural catheter could be a valid alternative to talc pleurodesis in selected patients with trapped lung syndrome (a lung that fails to reexpand after drainage of pleural effusion) and short life expectancy. However, the correct treatment depends on several factors such as performance status, expected survival, presence of lung reexpansion following pleural drainage and comorbidities.

To evaluate the Ventana IHC ALK (D5F3) assay for detecting anaplastic lymphoma kinase (ALK) protein expression in pleural effusion samples. Historical, selected (wild-type EGFR, K-RAS) pleural effusion cytologic blocks of lung adenocarcinoma samples (Study 1) and unselected lung adenocarcinoma pleural effusion cytologic blocks (Study 2) were tested by Ventana IHC ALK (D5F3) assay. Quantitative real-time-PCR was used to verify immunohistochemistry results. A total of 17 out of 100 (Study 1) and ten out of 104 (Study 2) pleural effusion samples were ALK expression positive by the Ventana IHC ALK (D5F3) assay. The ALK fusion results with immunohistochemistry and quantitative real-time-PCR had a concordance rate of 87.5% (κ = 0.886; p < 0.001). The Ventana IHC ALK (D5F3) assay is a reliable tool for detecting ALK protein expression in pleural effusion samples.

We compared the accuracy of pleural ultrasound versus chest CT versus chest radiograph (CXR) to determine radiographic complexity in predicting a complicated parapneumonic effusion (CPPE) defined by pleural fluid analysis. 66 patients with parapneumonic effusions were identified with complete data. Pleural ultrasound had a sensitivity of 69.2% (95% CI 48.2% to 85.7%) and specificity of 90.0% (95% CI 76.3% to 97.2%). Chest CT had a sensitivity of 76.9% (95% CI 56.3% to 91.0%) and specificity of 65.0% (95% CI 48.3% to 79.4%). CXR had a sensitivity of 61.5% (95% CI 40.6% to 79.8%) and specificity of 60.0% (95% CI 43.3% to 75.1%). Pleural ultrasound appears to be a superior modality to rule in a CPPE when compared with chest CT and CXR. Published by the BMJ Publishing Group Limited.

Summary Carbon nanotubes have fibre-like shape1 and stimulate inflammation at the surface of the peritoneum when injected into the abdominal cavity of mice2, raising concerns that inhaled nanotubes3 may cause pleural fibrosis and/or mesothelioma4. Here we show that multi-walled carbon nanotubes reach the sub-pleura in mice after a single inhalation exposure of 30 mg/m3 for 6 hours. Nanotubes were embedded in the sub-pleural wall and within sub-pleural macrophages. Mononuclear cell aggregates on the pleural surface increased in number and size after 1 day and nanotube-containing macrophages were observed within these foci. Sub-pleural fibrosis increased after 2 and 6 weeks following inhalation. None of these effects were seen in mice that inhaled carbon black nanoparticles or a lower dose of nanotubes (1 mg/m3). This work advances a growing literature on pulmonary toxicology of nanotubes5 and suggests that minimizing inhalation of nanotubes during handling is prudent until further long term assessments are conducted.

Pérez-Guzmán, C.; Barrera-Rodríguez, R.; Portilla-Segura, J.

2016-01-01

Background Malignant pleural mesothelioma is a rare, invasive and often fatal neoplasm that develops in the thin layer of tissue surrounding the lungs known as the pleura. Although rare, mesotheliomas do occur in the young; their characteristics are distinct from those of older patients. Case presentation This is a case report of a 17-year-old boy who had moderate dyspnea, cough, right-sided pleuritic chest pain, fever, headache and no weight loss. Physical examination showed a right pleural effusion and chest roentgenograms revealed a homogenous opacity on lower right hemithorax. Biochemical analysis of pleural fluid showed hemorrhagic/turbid effusion compatible with exudate. It was initially treated as an empyema. The pleural fluid culture was negative. Adenosine deaminase level was 34.3 U/L (admission) and 19.02 U/L (two weeks after). Pleural fluid smear and culture for Mtb were negative. During the open pleural biopsy, thickened pleura and multiple pale yellow nodules in the lung were observed. The histopathological report was compatible with malignant pleural mesothelioma. With this diagnosis, a chemotherapy regimen with cisplatin was initiated. After two cycles, the patient had no clinical and radiological improvement. The patient is currently under regular follow up. Conclusion MPM is rare in young adults and its clinical presentation makes it different from mesothelioma in elderly patients, so it will be necessary to identify the new risk factors that can identify these patients.

The prevalence of pleural effusion in Mexico is over 400 per 100 000 inhabitants. The etiology is infectious in 45.7% and neoplastic in 32.6%. Closed pleural biopsy sensibility is 48-70% in cancer and 50-59% in tuberculosis using Cope or Abrams needle. In 1989, Tru-cut needle biopsy was described in a small study for massive pleural effusions with a sensibility of 86%. Our Institute has a wide experience with this infrequently procedure with reliable results than using Cope needle. Diagnostic yield should be evaluated. We aimed to evaluate the diagnostic yield of Tru-cut vs. standard Cope biopsy in the histopathological diagnosis of pleural effusion. Experimental, not blinded, analytical, cross-sectional study. We studied 44 patients (24 male and 20 female) with exudative pleural effusion over a period of 14 months. Every patient underwent four Tru-cut and four Cope needle biopsies. The diagnostic yield of both methods was compared. The mean age of patients was 61.4 ± 12.2 years. The diagnosis was achieved in 25 (57%) of patients using Tru-cut and 22 (50%) of patients using Cope's closed pleural biopsy. The diagnostic value was not significantly higher (p = 0.41). The most common diagnoses were adenocarcinoma (20.5%), mesothelioma (15.9%) and tuberculosis (15.9%). The diagnostic yield of Tru-cut needle biopsy is slightly higher than Cope pleural biopsy, very similar to that reported previously. The experience in this procedure is an advantage in our clinical practice.

The performance of blind closed pleural biopsy (BCPB) in the study of pleural exudates is controversial. To assess the diagnostic yield of BCPB in clinical practice and its role in the study of pleural exudates. Data were retrospectively collected on all patients who underwent BCPB performed between January 1999 and December 2011. A total of 658 BCPBs were performed on 575 patients. Pleural tissue was obtained in 590 (89.7%) of the biopsies. A malignant pleural effusion was found in 35% of patients. The cytology and the BCPB were positive in 69.2% and 59.2% of the patients, respectively. Of the patients with negative cytology, 21 had a positive BCPB (diagnostic improvement, 15%), which would have avoided one pleuroscopy for every seven BCPBs that were performed. Of the 113 patients with a tuberculous effusion, granulomas were observed in 87 and the Lowenstein culture was positive in an additional 17 (sensitivity 92%). The overall sensitivity was 33.9%, with a specificity and positive predictive value of 100%, and a negative predictive value of 71%. Complications were recorded in 14.4% of patients (pneumothorax 9.4%; chest pain 5.6%; vasovagal reaction, 4.1%; biopsy of another organ 0.5%). BCPB still has a significant role in the study of a pleural exudate. If an image-guided technique is unavailable, it seems reasonable to perform BCPB before resorting to a pleuroscopy. These results support BCPB as a relatively safe technique.

Conventional methods for diagnosing tuberculous pleurisy (TB pleurisy) are either invasive or have a long turn-around-time. Performances of pleural adenosine deaminase (ADA), ADA2, interferon-gamma (IFN-γ), and interferon-gamma release assays (IGRA) as diagnostic tools for TB pleurisy were evaluated. Eighty-eight patients with lymphocyte-predominant pleural exudates between June 2010 and March 2011, including 31 with clinically diagnosed TB pleurisy, were prospectively studied. Pleural ADA and ADA2 activity were measured by colorimetric method, IFN-γ levels by enzyme-linked immuno-sorbent assay, and IGRA by enzyme-linked immuno-spot (T-SPOT.TB) assay. Pleural ADA, ADA2, and IFN-γ levels, but not the proportion of positive T-SPOT.TB assay, were significantly higher in patients with TB pleurisy than in those without TB pleurisy. The area under the receiver-operating-characteristic (ROC) curve was 0.920, 0.893, 0.875, and 0.544 for IFN-γ, ADA2, ADA, and T-SPOT.TB assay, respectively. The combination of ADA ≥ 40 IU/L and IFN-γ ≥ 75 pg/mL yielded a specificity of 100%. Pleural ADA, ADA2 and IFN-γ, but not T-SPOT.TB assay, are all sensitive and specific for TB pleurisy. In patients with lymphocyte-predominant pleural exudates, ADA ≥ 40 IU/L and IFN-γ ≥ 75 pg/mL in pleural effusion imply a very high probability of TB pleurisy.

PURPOSE We aimed to evaluate the efficacy of multidetector computed tomography (CT) imaging in diagnosis of pleural exudates and transudates using attenuation values. MATERIALS AND METHODS This retrospective study included 106 patients who were diagnosed with pleural effusion between January 2010 and June 2012. After the patients underwent chest CT, thoracentesis was performed in the first week. The attenuation values of the pleural effusions were measured in all patients. RESULTS According to Light’s criteria, 30 of 106 patients with pleural effusions had transudates, and the remaining patients had exudates. The Hounsfield unit (HU) value of the exudates (median, 12.5; range, 4–33) was significantly higher than that of the transudates (median, 5; range, 2–15) (P = 0.001). Additionally, when evaluated by disease subgroups, congestive heart failure and empyema were predictable in terms of median HU values of the pleural effusions with high and moderate sensitivity and specificity values (84.6% and 81.2%, respectively; 76.9% and 66.7%, respectively). Compared with other patients, the empyema patients had significantly more loculation and pleural thickening. CONCLUSION CT attenuation values may be useful in differentiating exu-dates from transudates. Although there is an overlap in most effusions, exudate can be considered when the CT attenuation values are >15 HU. Because of overlapping HU values, close correlation with clinical findings is essential. Additional signs, such as fluid loculation and pleural thickness, should be considered and may provide further information for the differentiation. PMID:24100060

Pleural tuberculosis: A concise clinical review.

Tuberculosis (TB) is the leading infectious cause of death worldwide, and the commonest cause of death in people living with HIV. Globally, pleural TB remains one of the most frequent causes of pleural exudates, particularly in TB-endemic areas and in the HIV positive population. Most TB pleural effusions are exudates with high adenosine deaminase (ADA), lymphocyte-rich, straw-coloured and free flowing, with a low yield on mycobacterial culture. TB pleurisy can also present as loculated neutrophil-predominant effusions which mimic parapneumonic effusions. Rarely, they can present as frank TB empyema, containing an abundance of mycobacteria. Up to 80% of patients have parenchymal involvement on chest imaging. The diagnosis is simple if M. tuberculosis is detected in sputum, pleural fluid or biopsy specimens, and the recent advent of liquid medium culture techniques has increased the microbiological yield dramatically. Where the prevalence of TB is high the presence of a lymphocyte-predominant exudate with a high ADA has a positive predictive value of 98%. In low prevalence areas, the absence of an elevated ADA and lymphocyte predominance makes TB very unlikely, and pleural biopsy should be performed to confirm the diagnosis. Pleural biopsy for liquid culture and susceptibility testing must also be considered where the prevalence of drug resistant TB is high. Treatment regimens are identical to those administered for pulmonary TB. Initial pleural drainage may have a role in symptom relief and in hastening the resolution of the effusion. Surgical intervention may be required in loculated effusions and empyemas. © 2018 John Wiley & Sons Ltd.

To evaluate the role of intrapleural positioning of a pleural catheter in early lung expansion and pleurodesis success in patients with recurrent malignant pleural effusion (RMPE). This was a retrospective study nested into a larger prospective cohort study including patients with RMPE recruited from a tertiary university teaching hospital between June of 2009 and September of 2014. The patients underwent pleural catheter insertion followed by bedside pleurodesis. Chest CT scans were performed twice: immediately before pleurodesis (iCT) and 30 days after pleurodesis (CT30). Catheter positioning was categorized based on iCT scans as posterolateral, anterior, fissural, and subpulmonary. We used the pleural volume on iCT scans to estimate early lung expansion and the difference between the pleural volumes on CT30 and iCT scans to evaluate radiological success of pleurodesis. Clinical pleurodesis success was defined as no need for any other pleural procedure. Of the 131 eligible patients from the original study, 85 were included in this nested study (64 women; mean age: 60.74 years). Catheter tip positioning was subpulmonary in 35 patients (41%), anterior in 23 (27%), posterolateral in 17 (20%), and fissural in 10 (12%). No significant differences were found among the groups regarding early lung expansion (median residual pleural cavity = 377 mL; interquartile range: 171-722 mL; p = 0.645), radiological success of pleurodesis (median volume = 33 mL; interquartile range: -225 to 257 mL; p = 0.923), and clinical success of pleurodesis (85.8%; p = 0.676). Our results suggest that the position of the tip of the pleural catheter influences neither early lung expansion nor bedside pleurodesis success in patients with RMPE. Avaliar o papel do posicionamento intrapleural do cateter pleural na expansão pulmonar precoce e no sucesso da pleurodese em pacientes com derrame pleural maligno recorrente (DPMR). Trata-se de um estudo retrospectivo aninhado em um estudo prospectivo de coorte maior com pacientes com DPMR recrutados em um hospital-escola universitário terciário entre junho de 2009 e setembro de 2014. Os pacientes foram submetidos a inserção de cateter pleural e, em seguida, pleurodese à beira do leito. A TC de tórax foi realizada duas vezes: imediatamente antes da pleurodese (TCi) e 30 dias após a pleurodese (TC30). Com base na TCi, a posição do cateter foi classificada em posterolateral, anterior, fissural e subpulmonar. Usamos o volume pleural na TCi para estimar a expansão pulmonar precoce e a diferença entre os volumes pleurais na TC30 e na TCi a fim de avaliar o sucesso radiológico da pleurodese. Considerou-se que a pleurodese teve êxito clínico quando não foi necessário realizar nenhum outro procedimento pleural. Dos 131 pacientes elegíveis do estudo original, 85 foram incluídos neste estudo aninhado (64 mulheres; média de idade: 60,74 anos). A posição da ponta do cateter foi subpulmonar em 35 pacientes (41%), anterior em 23 (27%), posterolateral em 17 (20%) e fissural em 10 (12%). Não houve diferenças significativas entre os grupos quanto à expansão pulmonar precoce (mediana da cavidade pleural residual = 377 ml; intervalo interquartil: 171-722 ml; p = 0,645), sucesso radiológico da pleurodese (mediana do volume = 33 ml; intervalo interquartil: -225 a 257 ml; p = 0,923) e sucesso clínico da pleurodese (85,8%; p = 0,676). Nossos resultados sugerem que a posição da ponta do cateter pleural não influencia nem a expansão pulmonar precoce nem o sucesso da pleurodese à beira do leito em pacientes com DPMR.

Radiographic findings of dengue fever have not yet been clearly elucidated in relation to clinical and serological findings, despite the fact that two-fifths of the world population lives in areas where the virus is endemic. The current study is a retrospective analysis of ultrasonographic (USG) features of patients presenting with probable dengue fever during the outbreak of DF of 2006 in North India. Case records of a 169 patients with probable dengue fever were included. Ten individual sonographic parameters were reviewed vis-à-vis ascites, hepatomegaly, splenomegaly, gall bladder wall edema (GBWE), pleural effusion (right or left or both), pericardial effusion, pericholecystic collection, perinephric collection. Subjects who had GB wall thickness >3 mm as measured on ultrasound were identified as positive for GBWE. The cases were analyzed in view of their serological profile. The mean age of the subjects was 27.9 +/- 13.4 years. The mean value of the platelet count was 57.4 +/- 22.3 x 103/cmm. The most common ultrasonographic feature was ascites (126, 74.6%) followed by gall bladder wall edema (122, 72%), hepatomegaly (78, 46.2%), splenomegaly (66, 39.1%) and pericholecystic collection (63, 37.3%); 48 (28.4%) subjects demonstrated evidence of pleural effusion on the right side, while 19 (11.2%) had bilateral effusion. None of the subjects had an isolated left pleural effusion. Twenty-seven (16%) subjects reported bleeding manifestations in the form of petechiae and five (3%) developed renal dysfunction. Presence of pleural and pericardial effusions was found to be specific while ascites and GBWE were identified as highly sensitive markers for seropositive Primary DF. Ultrasonographic evidence of ascites, pleuro-pericardial effusion, and gallbladder wall edema are rapidly acquired, non-invasive markers of dengue and can be helpful before serological investigations become available. These findings may indicate severity and may herald the onset of bleeding (petechiae) or predict the development of acute renal dysfunction.

Despite the usefulness of Pap tests for cancer screening, outcomes can be difficult to predict when atypical squamous cells (ASCs) are identified. According to the 2001 Bethesda system, ASCs can be subdivided into two groups: ASCs of undetermined significance (ASC-US); and ASCs, cannot exclude high-grade squamous intra-epithelial lesion (ASC-H). ASC-H interpretations are uncommon, and studies involving this type of lesion are based on small numbers of cases. Cross-sectional, retrospective study of 392 ASC-H cases. The follow-up outcomes of ASC-H cases that were diagnosed during routine primary screening between 2002 and 2008 were investigated, and relationships between clinicopathological parameters were assessed, particularly positive test for high-risk HPV (HPV) DNA, patient age at diagnosis and previous abnormal cytology. Of the 392 cases, high-grade squamous intra-epithelial lesion (HSIL) was detected in 111 (28.3%) cases, squamous cell carcinoma was detected in 15 (3.8%) cases, low-grade squamous intra-epithelial lesion was detected in 37 (9.4%) cases, reactive change was detected in 178 (45.4%) cases, atrophy was detected in 47 (12.0%) cases, and adenocarcinoma was detected in four (1.0%) cases. The prevalence of HSIL or greater was 27.8% for women aged ≥ 40 years, and 52.3% for women aged <40 years (p<0.001). HPV positivity in ASC-H smears was significantly associated with HSIL or greater, irrespective of age (<40 years, p=0.003; ≥ 40 years, p<0.001). ASC-H with previous abnormal cytology greater than ASC-US showed a significantly higher detection rate for HSIL or greater at follow-up (p<0.001). Patient age, positive HPV DNA test and previous abnormal cytology are useful predictors of underlying HSIL or greater in women with ASC-H. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

This study aims to investigate the effect of intrapleural polymeric films containing cisplatin on the local recurrence of malignant pleural mesothelioma in a rat tumour model. An orthotopic rat recurrence model of malignant pleural mesothelioma was used. Five animals per group were evaluated. Polymeric films (4.5 cm diameter) for the local delivery of anticancer drug were constructed: hyaluronate, chitosan and the combined dual-layer polymers were loaded with cisplatin at a concentration of 100 mgm(-2). Animals without any adjuvant therapy were used as control. Mesothelioma cells were injected subpleurally in the anaesthetised rats. Six days later, a pleural tumour of 5.5mm was resected and a left pneumonectomy and pleural abrasion were performed. Thereafter, the cisplatin-loaded and unloaded films or cisplatin solution were intrapleurally applied, according to randomisation. After 6 days, animals were euthanised and organs harvested for morphological and histological evaluations. The primary endpoint was the volume of tumour recurrence. The secondary endpoints were treatment-related toxicity; cisplatin serum concentration evaluated at different time points; and cisplatin concentration in the pleura measured at autopsy. Analysis of variance (ANOVA) was used for statistical analysis. Bonferroni correction was applied for comparison between all groups. Tumour volume was significantly reduced in the hyaluronate cisplatin and hyaluronate-chitosan cisplatin groups in comparison to control groups (p=0.001 and p<0.0001, respectively). Animals treated with hyaluronate-chitosan cisplatin had a tumour recurrence significantly lesser than animals treated with cisplatin solution (p=0.003) and hyaluronate cisplatin (p=0.032). No toxicity related to the different treatments was observed. On postoperative days 1 and 2, cisplatin was detected in the serum at a concentration six- and sevenfold significantly higher in the hyaluronate cisplatin and hyaluronate-chitosan cisplatin groups, in comparison to cisplatin solution, and was maintained over time. Cisplatin levels in the pleura were higher in the hyaluronate-chitosan cisplatin group than in all others. Hyaluronate-chitosan cisplatin was significantly effective in reducing tumour recurrence compared with cisplatin solution. Hyaluronate and hyaluronate-chitosan loaded with cisplatin assured significantly higher and more prolonged plasmatic drug concentrations than cisplatin solution without increasing toxicity.
