Objective: The aim of this study was to compare the value of contrast-enhanced ultrasonography (CEUS) with standard B-mode ultrasound (US) for diagnosis of splenic lymphoma involvement. Methods: From 04/2005 to 10/2008 n = 250 lymphoma patients were investigated by standard B-mode US. A homogeneous splenic echotexture was found in 199 patients (79%). To clarify the benefit of CEUS in this group a pilot series was performed with 16 of the 199 lymphoma patients. All patients with an abnormal splenic echotexture on standard B-Mode US (n = 51) including focal hypoechoic splenic lesions (n = 41) and an inhomogeneous splenic texture (n = 10) were studied by CEUS. CEUS data were retrospectively evaluated. The diagnoses included indolent lymphoma (n = 27), aggressive lymphoma (n = 14), and Hodgkin's disease (n = 10). Number and size of lesions were determined by B-mode US and CEUS. The visualisation of splenic lymphoma involvement by CEUS in comparison to B-mode US was classified as worse, equal, or better. Results: All patients with a homogeneous spleen on B-mode US (n = 16) had no visible focal lesions on CEUS. Study patients with focal lesions (n = 41) had a hypoechoic (n = 22) or isoechoic (n = 19) enhancement during the arterial phase, and a hypoechoic enhancement during the parenchymal phase (n = 41). The visualisation of focal splenic lymphoma was equal (n = 32), better (n = 6), or worse (n = 3). In all study patients with an inhomogeneous spleen on B-mode US (n = 10) no focal lesions were found by CEUS and the value of CEUS therefore was classified as worse. Conclusion: CEUS has no clear advantage for diagnosis of splenic lymphoma involvement.

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.

Extranodal non-B, non-T-cell lymphoma with bilateral tympanic bulla involvement in a cat

Full Text Available Case summary A 9-year-old spayed female domestic shorthair cat with clinical signs suggestive of chronic recurrent otitis media and recent seizures was presented with multifocal nervous system disease, including bilateral central and/or peripheral vestibular, cerebellar and forebrain deficits. Prior to presentation, there was inadequate improvement after 6 weeks of treatment for bilateral middle ear effusion from which a highly susceptible Staphylococcus species was cultured. This was followed by the development of seizures. Results of a complete blood count and serum chemistry were unremarkable, and a previous feline leukemia virus/feline immunodeficiency virus ELISA was negative. The cat was hospitalized overnight and had multiple seizures. The following morning the cat’s mentation worsened, and the cat lost ventilatory drive after induction for anesthesia in preparation for MRI. A brain herniation event was suspected, and the cat was euthanized prior to further diagnostics. On post-mortem examination both tympanic bullae were filled with a soft, tan-colored material. Histologically, this material was composed of neoplastic lymphocytes. In addition, neoplastic lymphocytes were found in the leptomeninges, brain parenchyma, submandibular lymph nodes and pancreas. The neoplastic lymphocytes were negative for both B- and T-lymphocyte immunohistochemical markers and PCR for antigen receptor rearrangements failed to amplify target DNA, indicating non-B, non-T-cell lymphoma. Relevance and novel information To our knowledge, this is the first report of lymphoma with confirmed bilateral tympanic bulla involvement in the human and veterinary literature. Neoplasia should be considered in cases of middle-ear effusion that do not improve adequately with appropriate antimicrobial therapy.

To investigate the CT and MR findings of muscular involvement by malignant lymphoma. Thirteen patients with biopsy-proved muscular involvement by malignant lymphoma were included in this study. Two patients were primary muscle lymphoma and 11 patients were muscle lymphoma by secondary involvement of malignant lymphoma. CT of 10 patients (6 pre-contrast CT and 9 postcontrast CT) and MRI of 6 patients (all with pre a nd post-contrast studies) were retrospectively analyzed. In the majority of patients (84.6%, 11/13), the appearance of muscular involvement was the diffuse enlargement of several muscles as like as a group. The muscles involved by malignant lymphoma showed iso-attenuation (5/6) and homogeneity (6/6) on pre-contrast CT scan, and high attenuation (5/9) or iso-attenuation (4/9) and homogeneity (7/9) on post-contrast CT scan. The signal intensity of involved muscle showed slightly hyper- (4/6) or iso-intense (2/6) and homogeneous (6/6) on T1-weighted images, and hyper-intense (6/6) and homogeneous (4/6) on T2- and Gadolinium-enhanced T1-weighted images. Adjacent bone change was demonstrated in 69.2% (9/13), subcutaneous fat change in 61.5% (8/13), and neurovascular encasement within involved muscle in 53.8% (7/13). The CT and MR findings of muscular involvement by malignant lymphoma were diffuse enlargement of several muscles with homogeneous attenuation or signal intensity, and frequent changes in adjacent bones and subcutaneous fat, or neurovascular encasement.

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.

To analyze the initial thoracic involvement by CT in a consecutive series of patients with lymphoma. A retrospective analysis was made of thoracic CT studies made at the time of diagnosis of 259 patients with lymphoma. Mediastinal pulmonary, pleural, pericardial and chest wall involvement was assessed by CT. Of 259 patients (129 men y 130 women), 56 had Hodgkin's disease (HD) and 203 had non-Hodgkin lymphoma (NHL). Forty-two percent (42.5%, 110/259) of the patients had chest involvement on CT: 33 of 56 patients with HD (58.9%) and 77 of 203 patients with NHL (37.9%). All the patients with thoracic HD) and 71.4% of patients with thoracic NHL, had mediastinal lymph node involvement. of the patients with thoracic involvement 12.1% (4/33) of the patient with HD and 23.3% (18/77) of the patients with NHL had pulmonary involvement. Thoracic involvement on CT was more frequent in HD. Mediastinal lymph node involvement was the most common finding fundamentally in HD. Pulmonary disease always occurred in the presence of mediastinal lymph node involvement in HD but could occur as an isolated finding in NHL. (Author) 24 refs

Highlights: • Sangivamycin induces the apoptosis of B cell lymphoma PEL cells. • Sangivamycin suppresses Erk signaling by inhibiting Erk phosphorylation in PEL cells. • The activation of Erk signaling is essential for PEL cell survival. • Sangivamycin induces the apoptosis of PEL cells without production of progeny virus. • Sangivamycin may serve as a novel drug for the treatment of PEL. - Abstract: Sangivamycin, a structural analog of adenosine and antibiotic exhibiting antitumor and antivirus activities, inhibits protein kinase C and the synthesis of both DNA and RNA. Primary effusion lymphoma (PEL) is an aggressive neoplasm caused by Kaposi’s sarcoma-associated herpesvirus (KSHV) in immunosuppressed patients and HIV-infected homosexual males. PEL cells are derived from post-germinal center B cells, and are infected with KSHV. Herein, we asked if sangivamycin might be useful to treat PEL. We found that sangivamycin killed PEL cells, and we explored the underlying mechanism. Sangivamycin treatment drastically decreased the viability of PEL cell lines compared to KSHV-uninfected B lymphoma cell lines. Sangivamycin induced the apoptosis of PEL cells by activating caspase-7 and -9. Further, sangivamycin suppressed the phosphorylation of Erk1/2 and Akt, thus inhibiting activation of the proteins. Inhibitors of Akt and MEK suppressed the proliferation of PEL cells compared to KSHV-uninfected cells. It is known that activation of Erk and Akt signaling inhibits apoptosis and promotes proliferation in PEL cells. Our data therefore suggest that sangivamycin induces apoptosis by inhibiting Erk and Akt signaling in such cells. We next investigated whether sangivamycin, in combination with an HSP90 inhibitor geldanamycin (GA) or valproate (valproic acid), potentiated the cytotoxic effects of the latter drugs on PEL cells. Compared to treatment with GA or valproate alone, the addition of sangivamycin enhanced cytotoxic activity. Our data thus indicate that

Purpose: We aimed to describe computed tomography (CT) findings in patients with peritoneal, omental and mesenteric lymphoma involvement. Materials and methods: We searched our archive retrospectively to find out patients with peritoneal, omental and mesenteric lymphoma involvement. We found 16 patients with non-hodgkin lymphoma meeting these criteria. CT studies of these patients were reevaluated for the presence of peritoneal involvement, ascites, omental mass, organomegaly, retroperitoneal lymphadenopathy, bowel wall thickening and other associated findings. Results: There were 14 males and 2 females with peritoneal and/or mesenteric and omental lymphoma involvement. Mean age was 39 (range 4-76). Subgroups of non-hodgkin lymphoma were diffuse large B-cell lymphoma (n = 11), small cell lymphocytic lymphoma (n = 2), small cleaved cell lymphoma (n = 1), T-cell lymphoma (n = 1) and Burkitt's lymphoma (n = 1). Peritoneal involvement was seen in 15 patients (93.8%) in the form of linear (n = 12) and nodular (n = 3) thickening. Ascites was seen in 12 (75%) patients. Omental and mesenteric masses were present in 10 (66.6%) and 10 (66.6%) patients, respectively. Bowel wall thickening, retroperitoneal lymphadenopathy and hepatosplenomegaly were also common and observed in 10, 10 and 11 patients, respectively. Solid organ involvement in the form of liver and splenic lesions was seen in 9 (56%) patients. Conclusion: Peritoneal involvement can be seen in many subtypes of lymphoma and most frequently in diffuse large B-cell lymphoma. Peritoneal lymphomatosis can mimic peritoneal carcinomatosis and should be included in the differential diagnosis list in patients with ascites, hepatosplenic lesions and unidentified cause of peritoneal thickening on CT in a male patient.

A computational profiling of changes in gene expression and transcription factors induced by vFLIP K13 in primary effusion lymphoma.

Directory of Open Access Journals (Sweden)

Full Text Available Infection with Kaposi's sarcoma associated herpesvirus (KSHV has been linked to the development of primary effusion lymphoma (PEL, a rare lymphoproliferative disorder that is characterized by loss of expression of most B cell markers and effusions in the body cavities. This unique clinical presentation of PEL has been attributed to their distinctive plasmablastic gene expression profile that shows overexpression of genes involved in inflammation, adhesion and invasion. KSHV-encoded latent protein vFLIP K13 has been previously shown to promote the survival and proliferation of PEL cells. In this study, we employed gene array analysis to characterize the effect of K13 on global gene expression in PEL-derived BCBL1 cells, which express negligible K13 endogenously. We demonstrate that K13 upregulates the expression of a number of NF-κB responsive genes involved in cytokine signaling, cell death, adhesion, inflammation and immune response, including two NF-κB subunits involved in the alternate NF-κB pathway, RELB and NFKB2. In contrast, CD19, a B cell marker, was one of the genes downregulated by K13. A comparison with K13-induced genes in human vascular endothelial cells revealed that although there was a considerable overlap among the genes induced by K13 in the two cell types, chemokines genes were preferentially induced in HUVEC with few exceptions, such as RANTES/CCL5, which was induced in both cell types. Functional studies confirmed that K13 activated the RANTES/CCL5 promoter through the NF-κB pathway. Taken collectively, our results suggest that K13 may contribute to the unique gene expression profile, immunophenotype and clinical presentation that are characteristics of KSHV-associated PEL.

Study Design: Descriptive study Place and Duration of Study: The study was carried out at Oncology department Combined Military Hospital Rawalpindi during July 2012 to April 2013. Materials and Methods: All newly diagnosed patients of NHL with extranodal involvement were included in the study. They were categorized as primary extranodal or secondary extranodal lymphomas. Histological pattern and site of involvement were studied. Results: The male to female ratio was 2.2:1 (Male 31, Female 14), and the mean age was 48.16 years (SD=13.40). Primary extranodal involvement was seen in 55.6% of patients. Secondary extranodal involvement was seen in 44.4% of patients. Diffuse large B-cell lymphoma (DLBCL) was the most common type of NHL observed in both primary and secondary extranodal involvement. Gastrointestinal tract was the most common site for primary extranodal involvement and bone marrow was the most common site for secondary extranodal involvement. Conclusion: High frequency of primary extranodal involvement was noted in our study. DLBCL was the most common morphological type observed. Gastrointestinal tract and secondary bone marrow involvement were the most common anatomical sites for primary and secondary extranodal involvement respectively. (author)

Purpose. To describe the CT findings of pathologically confirmed primary pulmonary lymphomas. Materials and methods. The CT examinations of 11 patients with pathologically proven primary pulmonary lymphoma (9 BALT lymphomas and 2 non-BALT lymphomas) were retrospectively reviewed by three radiologists. Evaluated findings included morphology (consolidation, mass, nodule), number and distribution of lesions. Other CT findings such as air bronchogram, lymphadenopathy atelectasis and pleural effusion were also assessed. Results. Pulmonary lesions were depicted as air-space consolidation (pneumonia-like) in 5 patients (45%), tumour-like rounded opacity in 4 (36%), and nodules in 4 (36%). Multiple and bilateral long lesions were seen in 3 patients (27%). Air bronchogram was present in 7 patients (63%), lymphadenopathy in 3 (27%), atelectasis in 4 (36%) and pleural effusion in only 1 (9%). Conclusions. Our results agree with previous studies regarding lesion patterns and their relative frequency. A smaller number of nodules and of multiple lesions were found compared with some previous studies. The most frequent pattern was airspace consolidation [it

Full Text Available Epigallocatechin-3-gallate (EGCG, the major constituent of green tea, has been shown to induce cell death in cancer cells. Primary effusion lymphoma (PEL is an aggressive neoplasm caused by human herpesvirus 8 (HHV8. In this study, we examined the role of EGCG on PEL cells in cell death and HHV8 replication. We performed trypan blue exclusion assay to assess the cell viability of PEL cells, flow cytometry analysis to examine the cell cycle distribution and reactive oxygen species (ROS generation, caspase-3 activity to assay apoptosis, acridine orange staining to determine autophagy, and immunoblotting to detect the protein levels involved in apoptosis and autophagy as well as mitogen activated protein kinases (MAPKs activation upon EGCG treatment. The expression of the HHV8 lytic gene was determined by luciferase reporter assay and reverse transcription-PCR, and viral progeny production was determined by PCR. Results revealed that EGCG induced cell death and ROS generation in PEL cells in a dose-dependent manner. N-acetylcysteine (NAC inhibited the EGCG-induced ROS and rescued the cell from EGCG-induced cell death. Even though EGCG induced ROS generation in PEL cells, it reduced the production of progeny virus from PEL cells without causing HHV8 reactivation. These results suggest that EGCG may represent a novel strategy for the treatment of HHV8 infection and HHV8-associated lymphomas.

Discordant lymphoma consisting of splenic mantle cell lymphoma and marginal zone lymphoma involving the bone marrow and peripheral blood: a case report

2011-09-01

Full Text Available Abstract Introduction Discordant lymphomas are rare entities characterized by the simultaneous presence of two distinct types of lymphomas in different anatomic sites. We describe a very rare case of simultaneous occurrence of splenic mantle cell lymphoma and marginal zone lymphoma involving the bone marrow and peripheral blood. Case presentation We report the case of a 60-year-old asymptomatic Caucasian woman in whom discordant lymphomas were discovered when a slight lymphocytosis and a conspicuous splenomegaly were observed. The different morphological, immunophenotypical and immunohistochemical features found in the different pathologic samples obtained from peripheral blood, bone marrow and spleen sections made it possible to differentiate two types of non-Hodgkin B-cell lymphomas: a mantle cell lymphoma infiltrating the spleen and a marginal zone lymphoma involving both the bone marrow and peripheral blood. Since a similar IgH gene rearrangement was found both in the bone marrow and in the spleen, the hypothesis of a common origin, followed by a different clonal selection of the neoplastic lymphocytes may be taken into consideration. Conclusion Our case emphasizes the usefulness of investigating simultaneous specimens from different anatomic sites from the same patient and the relevant diagnostic role of splenectomy.

Highlights: Black-Right-Pointing-Pointer Constitutive NF-{kappa}B signaling is essential for the survival and growth of PEL cells. Black-Right-Pointing-Pointer NF-{kappa}B signaling is upregulated by the proteasome-dependent degradation of I{kappa}B{alpha}. Black-Right-Pointing-Pointer Proteasome inhibitors suppress NF-{kappa}B signaling and induce apoptosis in PEL cells through stabilization of I{kappa}B{alpha}. Black-Right-Pointing-Pointer Proteasome inhibitors suppress viral replication in PEL cells during lytic KSHV infection. -- Abstract: Primary effusion lymphoma (PEL) is an aggressive neoplasm caused by Kaposi's sarcoma-associated herpesvirus (KSHV). This study provides evidence that proteasomal activity is required for both survival of PEL cells stably harboring the KSHV genome and viral replication of KSHV. We evaluated the cytotoxic effects of proteasome inhibitors on PEL cells. The proteasome inhibitors MG132, lactacystin, and proteasome inhibitor I dramatically inhibited cell proliferation and induced apoptosis of PEL cells through the accumulation of p21 and p27. Furthermore, proteasome inhibitors induced the stabilization of NF-{kappa}B inhibitory molecule (I{kappa}B{alpha}) and suppressed the transcriptional activity of NF-{kappa}B in PEL cells. The NF-{kappa}B specific inhibitor BAY11-7082 also induced apoptosis in PEL cells. The constitutive activation of NF-{kappa}B signaling is essential for the survival and growth of B cell lymphoma cells, including PEL cells. NF-{kappa}B signaling is upregulated by proteasome-dependent degradation of I{kappa}B{alpha}. The suppression of NF-{kappa}B signaling by proteasome inhibitors may contribute to the induction of apoptosis in PEL cells. In addition, proteasome activity is required for KSHV replication in KSHV latently infected PEL cells. MG132 reduced the production of progeny virus from PEL cells at low concentrations, which do not affect PEL cell growth. These findings suggest that proteasome

Full Text Available Primary effusion lymphoma (PEL caused by Kaposi’s sarcoma-associated herpesvirus (also known as human herpesvirus-8 shows serious lymphomatous effusion in body cavities. PEL is difficult to treat and there is no standard treatment strategy. Hippuristanol is extracted from Okinawan coral Isis hippuris, and inhibits translational initiation by blocking eukaryotic initiation factor 4A, an ATP-dependent RNA helicase, binding to mRNA. Recently, there has been much interest in targeting translation initiation as an anticancer therapy. Here, we show that treatment of PEL cell lines with hippuristanol resulted in cell cycle arrest at G1 phase, and induced caspases activation and apoptosis. Hippuristanol also reduced the expression of cyclin D2, CDK2, CDK4, CDK6 and prosurvival XIAP and Mcl-1 proteins. Activation of activator protein-1, signal transducers and activators of transcription protein 3 and Akt pathways plays a critical role in the survival and growth of PEL cells. Hippuristanol suppressed the activities of these three pathways by inhibiting the expression of JunB, JunD, c-Fos, signal transducers and activators of transcription protein 3 and Akt proteins. In a xenograft mouse model that showed ascites and diffused organ invasion of PEL cells, treatment with hippuristanol significantly inhibited the growth and invasion of PEL cells compared with untreated mice. The results of the in vitro and in vivo experiments underline the potential usefulness of hippuristanol in the treatment of PEL.

Epidural involvement is rarely associated with lymphoma, it being more typical of non-Hodgkin's lymphoma in advanced stages of the disease. The invasion of the epidural space is usually caused by the extension of a paravertebral mass or by the affected vertebrae. However, the epidural space alone can be involved. We present a case of epidural lymphoma in a patient who presented with clinical evidence of spinal cord compression. Magnetic resonance disclosed the existence of an epidural mass compressing and displacing the spinal cord without involving the adjacent vertebra or the associated paravertebral mass.

Kaposi's sarcoma-associated herpesvirus (KSHV) is the causative agent of primary effusion lymphoma (PEL) and Kaposi's sarcoma. PEL is a type of non-Hodgkin's B-cell lymphoma, affecting immunosuppressed individuals, such as post-transplant or AIDS patients. However, since PEL is resistant to chemotherapeutic regimens, new effective treatment strategies are required. Arctigenin, a natural lignan compound found in the plant Arctium lappa, has been widely investigated as a potential anticancer agent in the clinical setting. In the present study, we examined the cytotoxic effects of arctigenin by cell viability assay and found that arctigenin markedly inhibited the proliferation of PEL cells compared with KSHV-uninfected B-lymphoma cells under conditions of glucose deprivation. Arctigenin decreased cellular ATP levels, disrupted mitochondrial membrane potential and triggered caspase-9-mediated apoptosis in the glucose-deprived PEL cells. In addition, western blot analysis using phospho-specific antibodies were used to evaluate activity changes in the signaling pathways of interest. As a result, arctigenin suppressed the activation of the extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (p38 MAPK) signaling pathways by inhibiting ERK and p38 MAPK phosphorylation in the glucose-deprived PEL cells. We confirmed that an inhibitor of ERK (U0126) or p38 MAPK (SB202190 and SB203580) suppressed the proliferation of the BC3 PEL cells compared with the KSHV-negative DG75 cells. Moreover, RT-PCR and luciferase reporter assay revealed that arctigenin and p38 MAPK inhibition by SB202190 or SB203580 downregulated the transcriptional expression of unfolded protein response (UPR)‑related molecules, including GRP78 and ATF6α under conditions of glucose deprivation. Finally, we confirmed that arctigenin did not affect KSHV replication in PEL cells, suggesting that arctigenin treatment for PEL does not contribute to the risk of de novo KSHV

Full Text Available Primary effusion lymphoma (PEL or body cavity lymphoma is a rare type of extra nodal lymphoma of B-cell origin that presents as lymphomatous effusion(s without any nodal enlargement or tumor masses. It belongs to the group of AIDS related non-Hodgkin’s lymphomas. First described in 1996 in HIV infected individuals who were coinfected with Kaposi’s sarcoma-associated herpesvirus (KSHV or HHV-8 virus, it was included as a separate entity in WHO classification of tumors of hematopoietic and lymphoid tissue in the year 2001. The definition included association with HHV-8 virus as a mandatory diagnostic criterion. However, cases were later reported where PEL-like disease process was diagnosed in HHV-8 negative patients. This was eventually recognized as a rare but distinct entity termed as “HHV-8-unrelated PEL-like lymphoma”. Herein, we are reporting a case of an elderly patient who presented with a large pleuropericardial effusion and was eventually diagnosed with this entity. Till date, only around 50 cases of HHV-8-unrelated PEL-like lymphoma have been reported and our case being EBV, HIV, and Hepatitis C negative makes it very unique and rare occurrence. We are also presenting a review of relevant literature focused mainly on comparing outcomes in patients treated with and without chemotherapy.

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.

Highlights: • Seven fullerenes were evaluated in terms of their cytotoxic effects on B-lymphomas. • Pyrrolidinium fullerene induced apoptosis of KSHV-infected B-lymphoma PEL cells. • The activation of Akt is essential for PEL cell survival. • Pyrrolidinium fullerene activated caspase-9 by inactivating Akt in PEL cells. • Pyrrolidinium fullerene have potential as novel drugs for the treatment of PEL. - Abstract: Primary effusion lymphoma (PEL) is a subtype of non-Hodgkin’s B-cell lymphoma and is an aggressive neoplasm caused by Kaposi’s sarcoma-associated herpesvirus (KSHV) in immunosuppressed patients. In general, PEL cells are derived from post-germinal center B-cells and are infected with KSHV. To evaluate potential novel anti-tumor compounds against KSHV-associated PEL, seven water-soluble fullerene derivatives were evaluated as potential drug candidates for the treatment of PEL. Herein, we discovered a pyrrolidinium fullerene derivative, 1,1,1′,1′-tetramethyl [60]fullerenodipyrrolidinium diiodide, which induced apoptosis of PEL cells via a novel mechanism, the caspase-9 activation by suppressing the caspase-9 phosphorylation, causing caspase-9 inactivation. Pyrrolidinium fullerene treatment reduced significantly the viability of PEL cells compared with KSHV-uninfected lymphoma cells, and induced the apoptosis of PEL cells by activating caspase-9 via procaspase-9 cleavage. Pyrrolidinium fullerene additionally reduced the Ser473 phosphorylation of Akt and Ser196 of procaspase-9. Ser473-phosphorylated Akt (i.e., activated Akt) phosphorylates Ser196 in procaspase-9, causing inactivation of procaspase-9. We also demonstrated that Akt inhibitors suppressed the proliferation of PEL cells compared with KSHV-uninfected cells. Our data therefore suggest that Akt activation is essential for cell survival in PEL and a pyrrolidinium fullerene derivative induced apoptosis by activating caspase-9 via suppression of Akt in PEL cells. In addition, we evaluated

In order to determine the value of CT in detecting lymphomatous involvement of the liver, 57 autopsied cases (48 cases of non-Hodgkin lymphoma and 9 of Hodgkin's disease) were analyzed in detail. Additionally, 90 recent cases of abdominal CT with liver study in the initial staging were reviewed and 6 cases in which the liver had been examined within 2 weeks before autopsy were compared for macroscopic and pathologic findings. The following results were obtained. 1) Autopsy findings in 57 cases of malignant lymphoma. (1) Hepatic involvement was demonstrated in 56% of the patients with non-Hodgkin lymphoma and in 67% of those with Hodgkin's disease. (2) Of these patients with hepatic involvement, intrahepatic nodular lesions over 1.0cm in diameter were macroscopically identified in 22% of the cases of non-Hodgkin lymphoma and 33% of those with Hodgkin's disease. (3) Lymphomatous involvements were seen in many organs in the cases of hepatic involvement. 2) CT examinations of 90 cases for the initial staging showed no significant abnormality in the liver or spleen. 3) Of the 6 cases in which the liver was examined by CT within about 2 weeks before autopsy, lymphomatous involvemet was pathologically diagnosed in 5. Of these, only one having multiple nodules larger than the tip of a thumb was correctly diagnosed by CT. 4) Hepatic involvement of lymphoma was thought to be the end stage, and minimal or early disease was detected in the region of Glisson's capsule. The above findings indicate that early hepatic involvement is not likely to be detected by CT at the present time. (author)

Mediastinal non-Hodgkin's lymphoma in children is known to have an adverse prognosis, that is called ''lymphoblatic lymphoma''. Recently, chemotherapy for leukemia using multiple agents has been applied for non-Hodgkin's lymphoma in children, and this has improved relapse-free survival. Radiotherapy has been employed in order to reduce local recurrence. Two children received whole thoracic irradiation (10 Gy) who had mediastinal mass with malignant pleural effusion, then control of the effusion was achieved. Thereafter, radiation field was decreased in size to mantle field, and main tumor was treated to 30 Gy. In the course of treatment, mediastinal tumor was disappeared. Thereafter, radiation field was decreased in size to mantle field, and main tumor was treated to 30 Gy. In the course of treatment, mediastinal tumor was disappeared. For one child with only a mediastinal mass, mantle field was employed. He was treated to 30 Gy with chemotherapy. but he had CNS relapse. CNS prophylaxis is of considerable importance in this lymphoma according to the protocol of leukemia. (author)

Full Text Available Abstract Background Multiple Myeloma presenting as a pleural effusion is extremely rare. It is usually a late complication and is associated with a poor prognosis. Case Presentation A 40-year-old male presented with dyspnea and fever of six months duration. Clinical diagnosis of pulmonary tuberculosis was considered. X-ray chest showed bilateral pleural effusion. Pleural cytology revealed numerous plasma cells, some of which were binucleated and atypical. Cytological differential diagnosis included: Myelomatous effusion and Non-Hodgkin's Lymphoma deposit (Immunoblastic type. Bone marrow biopsy, serum protein electrophoresis and bone scan confirmed the diagnosis of multiple myeloma (Plasmablastic type. Conclusion Myelomatous pleural effusion as an initial presentation although extremely rare, should always be considered in presence of atypical plasma cells irrespective of age.

To assess abdominal CT images in lymphoma patients for the study of extra nodal abdominal involvement. Ninety-two patients diagnosed as having lymphoma were studied retrospectively. All the patients underwent abdominopelvic CT with oral and intravenous contrast (except in one patient who was allergic). In every case, the diagnosis was confirmed by biopsy or radiological follow-up after treatment had been completed. Fifty-two patients (56.5%) presented infiltration of extra nodal organs. The organs most frequently involved were liver and spleen, followed by the gastrointestinal tract, the musculoskeletal system and the genitourinary tract. The findings in this study coincide with those reported elsewhere with the exception of the splenic involvement the incidence of which was lower in the present series. (Author) 17 refs

Palliative Treatment of Malignant Pleural Effusion

Directory of Open Access Journals (Sweden)

Chenyang Liu

2015-01-01

Full Text Available Malignant pleural effusion (MPE is a common clinical problem caused by cancers. Pleural effusion can be the first sign of cancer in more than 25% of patients. Lung cancer and breast cancer are the most common cancers that metastasize to the pleura in men and women, respectively. Other cancers, including, but not limited to, lymphomas, ovarian cancer, stomach cancer, and several unknown primary cancers can also lead to MPE. Dyspnea and chest pain are the most common symptoms of MPE along with other symptoms such as a cough, weight loss, anorexia, fatigue, and weakness. Aggravation of these symptoms is closely related to the rate of accumulation of pleural effusion. Treatment options to MPE are determined by the type and extent of the underlying malignancy. The major goals of the treatment are to relieve symptoms, restore functions, improve the quality of life, and minimize the duration of hospital stay and costs. Although some patients can be treated with systemic therapies, most of these treatments are temporary, and MPE would recur soon. Hence, further palliative treatments to effectively control pleural effusions and relieve symptoms are necessary. This review addresses the pathophysiology of MPE and the treatment options for patients with MPE.

Full Text Available Introduction: Gastrointestinal tract is the most common site of involvement in non-Hodgkin’s lymphomas. Appropriate treatment regiments were not defined because of rare involvement. In the present study we aimed to evaluate treatment response of non-Hodgkin’s lymphoma patients with stomach involvement.    Methodology: 26 patients with stomach involvement were retrospectively analyzed between 01/01/1998 and 01/06/2014. Descriptive statistic was performed to analyze data.Results: 20 of the patients (76.9% were composed of primary stomach non-Hodgkin lymphoma, 6 of the patients (23.1% were composed of patients secondary involvement of the advanced stage disease. All of the patients were subtypes of B cell lymphoma. 3 of the patients (11.5% was indolent, 22 of the patients (84.6% was aggressive, and 1 of them (3.8% was very aggressive. Diffuse large B cell lymphoma was 72.9%; Maltoma was 8.7%, and Mantle cell lymphoma was %3.8. Complete response was achieved at 10 patients, partial response was achieved in 1 patient, and 7 patients were failed to response the treatment. Treatment response, and overall survival of low grade and high grade patients, both according to Ann-Arbor and Lugano classification systems were similar. Patients with elevated sedimentation rate had significant lower survival than patients with normal sedimentation rate (p=0.027.Discussion: Together with the data from recent studies, aggressive treatment approach without organ preservation should not be performed on patients without higher inflammatory response and early stage presentation. Sedimentation rate might help to clinicians for the treatment of choice.

Full Text Available Non-Hodgkin lymphoma is a common childhood T-cell and B-cell neoplasm that originates primarily from lymphoid tissue. Cutaneous involvement can be in the form of a primary extranodal lymphoma, or secondary to metastasis from a non-cutaneous location. The latter is uncommon, and isolated cutaneous involvement is rarely reported. We report a case of isolated secondary cutaneous involvement from nodal anaplastic large cell lymphoma (CD30 + and ALK + in a 7-year-old boy who was on chemotherapy. This case is reported for its unusual clinical presentation as an acute febrile, generalized papulonodular eruption that mimicked deep fungal infection, with the absence of other foci of systemic metastasis.

2008-05-01

Full Text Available Abstract Background Primary Non-Hodgkin's Lymphoma (PHNL of the breast is a rare entity, while secondary involvement of the breast with diffuse disease of Non-Hodgkin's lymphoma (NHL is more common. However, PNHL is the most frequent haematopoietic tumour of the breast. Diagnostic criteria for PNHL of the breast are presence of technically adequate pathologic specimens, close association of mammary tissue and lymphomatous infiltrate, no prior diagnosis of an extarammamary lymphoma, and no evidence of concurrent widespread disease, except for ipsilateral axillary lymph nodes if concomitant with the primary lesion. Case presentation A 57-year-old woman was recalled because her screening mammograms revealed three separate lesions in her right breast and one in the left. Histology of the lesions confirmed lymphoma in one breast with ductal carcinoma in the other. Conclusion Most of reported cases in literature have been involving the right breast, and almost all the patients were females. NHLs of the breast typically present as unilateral mass; the frequency of bilateral disease at first presentation ranges from 5–25%. Our objective is to report a case of primary lymphoma of the breast involving both axillae with concomitant bilateral primary breast cancer which has not been reported yet to our best of knowledge in literature.

Full Text Available We present a 56-year-old woman with bilateral pleural effusions, widespread enlarged lymph nodes, and soft tissue masses located within the renal pelvis. The initially working diagnosis was tuberculosis and lymphoma. Further pathological examination of the lymph node biopsy confirmed a diagnosis of extramedullary hematopoiesis, and a bone marrow biopsy revealed myelofibrosis. Unlike common treatment options such as radiotherapy and/or surgery, intrathoracic cisplatin and dexamethasone for the treatment of pleural effusions secondary to extramedullary hematopoiesis demonstrated an improvement in feasibility and efficacy in the present case.

Diffuse large B-cell lymphoma is the most common type of non-Hodgkin's lymphoma. More than 50% of patients have some site of extra-nodal involvement at diagnosis,including the gastrointestinal tract and bone marrow.However, a diffuse large B-cell lymphoma presenting as acute pancreatitis is rare. A 57-year-old female presented with abdominal pain and matted lymph nodes in her axilla. She was admitted with a diagnosis of acute pancreatitis. Abdominal computed tomography (CT) scan showed diffusely enlarged pancreas due to infiltrative neoplasm and peripancreatic lymphadenopathy. Biopsy of the axillary mass revealed a large B-cell lymphoma.The patient was classified as stage Ⅳ, based on the Ann Arbor Classification, and as having a high-risk lymphoma,based on the International Prognostic Index. She was started on chemotherapy with CHOP (cyclophosphamide,doxorubicin, vincristine and prednisone). Within a week after chemotherapy, the patient's abdominal pain resolved. Follow-up CT scan of the abdomen revealed a marked decrease in the size of the pancreas and peripancreatic lymphadenopathy. A literature search revealed only seven cases of primary involvement of the pancreas in B-cell lymphoma presenting as acute pancreatitis. However, only one case of secondary pancreatic involvement by B-cell lymphoma presenting as acute pancreatitis has been published. Our case appears to be the second report of such a manifestation.Both cases responded well to chemotherapy.

Detection of EML4-ALK in lung adenocarcinoma using pleural effusion with FISH, IHC, and RT-PCR methods.

Directory of Open Access Journals (Sweden)

Leilei Liu

Full Text Available Anaplastic lymphoma kinase (ALK and echinoderm microtubule-associated protein-like 4 (EML4 gene rearrangements occur in approximately 5% of non-small-cell lung cancers (NSCLC, leading to the overexpression of anaplastic lymphoma kinase and predicting a response to the targeted inhibitor, crizotinib. Malignant pleural effusion occurs in most patients with advanced lung cancer, especially adenocarcinoma, and tissue samples are not always available from these patients. We attempted to clarify the feasibility of detecting the EML4-ALK fusion gene in pleural effusion cells using different methods. We obtained 66 samples of pleural effusion from NSCLC patients. The pleural effusion fluid was centrifuged, and the cellular components obtained were formalin fixed and paraffin embedded. The EML4-ALK fusion gene status was determined with fluorescent in situ hybridization (FISH, reverse transcription-polymerase chain reaction (RT-PCR, and immunohistochemistry (IHC. EML4-ALK was detected in three of 66 patient samples (4.5% with RT-PCR. When the RT-PCR data were used as the standard, one false positive and one false negative samples were identified with IHC; and one false negative sample was identified with FISH. These results suggest that a block of pleural effusion cells can be used to detect the EML4-ALK fusion gene. IHC had good sensitivity, but low specificity. FISH had low sensitivity, but high specificity. RT-PCR is a good candidate method for detecting EML4-ALK in blocks of pleural effusion cells from lung cancer patients.

Role of defective Oct-2 and OCA-B expression in immunoglobulin production and Kaposi's sarcoma-associated herpesvirus lytic reactivation in primary effusion lymphoma.

Primary effusion lymphoma (PEL) is a distinct type of B-cell non-Hodgkin lymphoma characterized by the presence of Kaposi's sarcoma-associated herpesvirus (KSHV/human herpesvirus 8). Despite having a genotype and gene expression signature of highly differentiated B cells, PEL does not usually express surface or cytoplasmic immunoglobulin (Ig). We show the lack of Oct-2 and OCA-B transcription factors to be responsible, at least in part, for this defect in Ig production. Like Ig genes, ORF50, the key regulator of the switch from latency to lytic reactivation, contains an octamer motif within its promoter. We therefore examined the impact of Oct-2 and OCA-B on ORF50 activation. The binding of Oct-1 to the ORF50 promoter has been shown to significantly enhance ORF50 transactivation. We found that Oct-2, on the other hand, inhibited ORF50 expression and consequently lytic reactivation by competing with Oct-1 for the octamer motif in the ORF50 promoter. Our data suggest that Oct-2 downregulation in infected cells would be favorable to KSHV in allowing for efficient viral reactivation.

To assess chest high-resolution computed tomography (HRCT) findings in patients with acute transformation of adult T cell leukaemia/lymphoma (ATLL). We retrospectively identified 72 consecutive patients at our institution with ATLL between October 2000 and March 2014. The cases included acute type (n = 20), lymphoma type (n = 21), smouldering type (n = 24) and chronic type (n = 7). Sixteen (7 men, 9 women; aged 36-85 years, mean 63.3 years) of 31 patients (24 with smouldering and seven with chronic type; 51.6 %) developed acute transformation of ATLL, and had undergone chest HRCT examinations. Parenchymal abnormalities, enlarged lymph nodes, pericardial effusion, pleural effusion and skin lesions were evaluated on HRCT. Chest HRCT of 15 of the 16 patients showed abnormal findings, including ground-glass opacity (GGO) (n = 8), consolidation (n = 5), interlobular septal thickening (n = 5) and nodules (n = 5). Pleural effusion was found in five patients, lymph node enlargement in 10 patients and multiple skin thickening in two patients. Almost all patients with acute transformation of ATLL had abnormal findings on chest HRCT, which consisted mainly of lymph node enlargement, GGO, interlobular septal thickening, nodules and bilateral pleural effusions.

Kaposi sarcoma-associated herpesvirus (KSHV) is the etiologic agent of primary effusion lymphomas (PEL). PEL cell lines infected with KSHV, but negative for Epstein-Barr virus have a tumorigenic potential in non-obese diabetic/severe combined immunodeficient mice and result in efficient engraftment and formation of malignant ascites with notable abdominal distension, consistent with the clinical manifestations of PEL in humans. Using this preclinical mouse model, we demonstrate that the combination of arsenic trioxide and interferon-alpha (IFN) inhibits proliferation, induces apoptosis and downregulates the latent viral transcripts LANA-1, v-FLIP and v-Cyc in PEL cells derived from malignant ascites. Furthermore, this combination decreases the peritoneal volume and synergistically increases survival of PEL mice. These results provide a promising rationale for the therapeutic use of arsenic/IFN in PEL patients.

We present the clinical and radiological findings in 12 HIV-positive patients with gastrointestinal involvement secondary to non-Hodgkin's lymphoma, focusing on the value of the different diagnostic techniques employed (barium studies, ultrasonography and CT) and the differential diagnosis in view of our findings in these patients. We have reviewed the case histories of 58 HIV-positive patients diagnosed as having non-Hodgkin's lymphoma focusing on the results of barium studies, ultrasonography and CT scanning. According to barium studies, ultrasonography and CT, 12 patients (21%) presented gastrointestinal involvement, located in stomach (n=3D5), duodenum (n=3D2), small bowel (n=3D4), mesentery (n=3D1) and perianal region ( n=3D1). Enlarged abdominal lymph nodes were detected in 10 patients (83%). Six patients (50%) presented extraintestinal lymphomatous involvement and four (30%) had extraabdominal involment. Barium studies and CT were useful in the detection of the lesions of all the patients in whom these techniques were performed. CT also allowed the assessment of extraintestinal involvement. Ultrasonography showed poor sensitivity in the study of gastrointestinal involvement, but was effective in the detection of adenophathy. (Author) 27 refs

This paper reports a case of malignant lymphoma which was originated from the breast, followed by multiple involvement in the brain, and finally developed intraocular infiltration. These lesions disappeared by irradiation therapy. A 51 years old housewife was admitted to our hospital for the further evaluation and treatment of decreased bilateral visual acuity on May 1981. On May 1976, she noticed a solid tumor of the left breast, and total mastectomy disclosed malignant lymphoma (non-Hodgkin lymphoma, lymphocytic type). On August 1980, she developed diplopia and amnesia. CT scan revealed multiple involvements in brain and cobalt therapy resulted in good response. The ophthalmologic diagnosis was uveitis, but it was impossible to rule out the ophthalmic infiltration of malignant lymphoma and 60 Co irradiation (total 2,976 rad) to the bilateral eyes and systemic CHOP therapy were carried out. Consequently, her visual acuity recovered to 0.6, and she is now following ambulatory course. Although non-Hodgkin lymphomas have been reported to originate frequently from non lymphoid tissues, the breast as the primary site is rare and the intracerebral infiltration as an involvement of central nervous system is quite rare. Furthermore, malignant lymphoma of the eyes, especially intraocular involvement is infrequent in incidence. The diagnosis of uveitis due to malignant lymphoma is considered to be difficult because of lack in specific findings. (author)

Primary effusion lymphoma (PEL) is a rare aggressive subset of non-Hodgkin B-cell lymphoma. It is caused by Kaposi sarcoma-associated herpesvirus/human herpesvirus type 8 (KSHV/HHV8). It occurs mainly, but not exclusively, in HIV-positive patients. PEL predominantly develops in serous cavities and occasionally in extracavitary regions. PEL carries a very poor prognosis with a median survival time of <6 months. Indeed, currently used treatment modalities such as CHOP chemotherapy are far from achieving complete and sustainable remission. Therefore, there is no clear standard of care established in the treatment of PEL patients, stressing the need for novel-targeted approaches. Here, we have attempted a comprehensive assessment of the treatment of PEL, discussed avant-garde therapies and updated the state of preclinical research with promising clinical applications in the field. These include inhibitors of viral replication, modulators of cell signaling and inflammation, nuclear factor kappa B (NF-κB) and histone deacetylase inhibitors, and recently the combination of arsenic trioxide and interferon-alpha. Some of these targeted therapies have not yet reached clinical studies, although others were used in a few individual case reports with low numbers of patients. We also describe the first case of a 77-year-old, HIV-negative, HHV8-positive patient diagnosed with PEL limited to the pleural and peritoneal cavities. He received lenalidomide 25 mg/day for 21 days every 28 days. Treatment was well tolerated with no side effects. He rapidly improved after 1 month of treatment and progressively achieved complete remission persistent after 18 months of therapy. We believe that this review will bridge an important gap between classical chemotherapy and modern approaches of targeted therapy. Finally, our findings warrant further evaluation of lenalidomide in future prospective clinical studies

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.

Full Text Available Endobronchial involvement of extrapulmonary malignant tumors is uncommon and mostly associated with breast, kidney, colon, and rectum carcinomas. A 68-year-old male with a prior diagnosis of colon non-Hodgkin lymphoma (NHL was admitted to the hospital with a complaint of cough, sputum, and dyspnea. The chest radiograph showed right hilar enlargement and opacity at the right middle zone suggestive of a mass lesion. Computed tomography of thorax revealed a right-sided mass lesion extending to thoracic wall with the destruction of the third and the fourth ribs and a right hilar mass lesion. Fiberoptic bronchoscopy was performed in order to evaluate endobronchial involvement and showed stenosis with mucosal tumor infiltration in right upper lobe bronchus. The pathological examination of bronchoscopic biopsy specimen reported diffuse large B-cell lymphoma and the patient was accepted as the endobronchial recurrence of sigmoid colon NHL. The patient is still under treatment of R-ICE (rituximab-ifosfamide-carboplatin-etoposide chemotherapy and partial regression of pulmonary lesions was noted after 3 courses of treatment.

Immunoglobulin G4-related disease (IgG4-RD) is a recently described immune-mediated fibroinflammatory disease with a characteristic histopathologic appearance that can affect various organs. We report a 43-year-old Chinese female patient with IgG4-RD involving polyserous effusions with reports of worsening exertional dyspnea for 3 months. Laboratory blood tests revealed that serum interleukin (IL)-6, carbohydrate antigens (CA-199 and CA-125), and alpha-fetoprotein levels were significantly increased, but serum IgG4 levels were normal. Repeat pleural effusion and ascite analysis showed lymphocyte-predominant exudates. In addition, computed tomography scan showed massive pleural effusion in the right pleural cavity, abdominal effusion, and some pericardial effusion with a partial compression atelectasis. Further, medical thoracoscopy was performed to examine the pleural cavity and found multiple nodules on the pleura and partly thickened pleura with a reddish color. Histopathologic and immunohistochemical examination revealed marked lymphocytes and IgG4-positive plasma cell infiltration. The patient was finally diagnosed with IgG4-RD according to the comprehensive diagnostic criteria, although the patient presented similar serological and pathological manifestations of Castleman disease (CD). Our case suggests that IgG4-RD may be one of the causes of polyserous effusions and shows the difficulties in differentiating between IgG4-RD and CD.

Full Text Available Since nasal NK/T cell lymphoma and NK/T cell lymphoma nasal type are rare diseases, gastric involvement has seldom been seen. We report a unique case of a patient with a primary NK/T cell lymphoma nasal type of the stomach with skin involvement. The patient had no history of malignant diseases and was diagnosed with hematemesis and intense bleeding from his gastric primary site. Shortly after this event, exanthemic skin lesions appeared with concordant histology to the primary site. Despite chemotherapy, the patient died one month after the first symptomatic appearance of disease.

Heart of Lymphoma: Primary Mediastinal Large B-Cell Lymphoma with Endomyocardial Involvement

Elisa Rogowitz

2013-01-01

Full Text Available Primary mediastinal B-cell lymphoma (PMBCL is an uncommon aggressive subset of diffuse large B-cell lymphomas. Although PMBCL frequently spreads locally from the thymus into the pleura or pericardium, it rarely invades directly through the heart. Herein, we report a case of a young Mexican female diagnosed with PMBCL with clear infiltration of lymphoma through the cardiac wall and into the right atrium and tricuspid valve leading to tricuspid regurgitation. This was demonstrated by cardiac MRI and transthoracic echocardiogram. In addition, cardiac MRI and CT scan of the chest revealed the large mediastinal mass completely surrounding and eroding into the superior vena cava (SVC wall causing a collar of stokes. The cardiac and SVC infiltration created a significant therapeutic challenge as lymphomas are very responsive to chemotherapy, and treatment could potentially lead to vascular wall rupture and hemorrhage. Despite the lack of conclusive data on chemotherapy-induced hemodynamic compromise in such scenarios, her progressive severe SVC syndrome and respiratory distress necessitated urgent intervention. In addition to the unique presentation of this rare lymphoma, our case report highlights the safety of R-CHOP treatment.

Full Text Available Abstract Background Kikuchi-Fujimoto's disease (KFD, also called histiocytic necrotizing lymphadenitis, is a rare, idiopathic and self-limited condition usually characterized by cervical lymphadenopathy and fever, most often affecting young patients. Aetiology is unknown. Differential diagnosis includes mainly malignant lymphoma, tuberculous lymphadenitis and systemic lupus erythematosus (SLE, so early diagnosis is crucial. Pleuropulmonary involvement due to isolated KFD has been seldom reported. Case Presentation a 32-year-old man, on treatment for iatrogenic hypothyroidism, was admitted due to high grade fever and painful cervical lymphadenopathies. KFD was diagnosed by lymph node biopsy. Some days after admission the patient got worse, he developed generalized lymphadenopathy, bilateral pleural effusion and interstitial lung disease. All of them resolved with prednisone and after two years of following up he remains asymptomatic and without evidence of any other associated disease. Conclusion Pleural effusion and interstitial lung disease are very uncommon manifestations of KFD. In our experience, treatment with oral prednisone was effective.

Cooperative roles for emmprin and LYVE-1 in the regulation of chemoresistance for primary effusion lymphoma

The Kaposi’s sarcoma-associated herpesvirus is the causative agent of primary effusion lymphoma (PEL), for which cytotoxic chemotherapy represents the standard of care. The high mortality associated with PEL may be explained in part by resistance of these tumors to chemotherapy. The membrane-bound glycoprotein emmprin (CD147) enhances chemoresistance in tumors through effects on transporter expression, trafficking and interactions. Interactions between hyaluronan and hyaluronan receptors on the cell surface also facilitate emmprin-mediated chemoresistance. Whether emmprin or hyaluronan-receptor interactions regulate chemotherapeutic resistance for virus-associated malignancies is unknown. Using human PEL tumor cells, we found that PEL sensitivity to chemotherapy is directly proportional to expression of emmprin, the lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1) and a drug transporter known as the breast cancer resistance protein/ABCG2 (BCRP), and that emmprin, LYVE-1 and BCRP interact with each other and colocalize on the PEL cell surface. In addition, we found that emmprin induces chemoresistance in PEL cells through upregulation of BCRP expression, and RNA interference targeting of emmprin, LYVE-1 or BCRP enhances PEL cell apoptosis induced by chemotherapy. Finally, disruption of hyaluronan-receptor interactions using small hyaluronan oligosaccharides reduces expression of emmprin and BCRP while sensitizing PEL cells to chemotherapy. Collectively, these data support interdependent roles for emmprin, LYVE-1 and BCRP in chemotherapeutic resistance for PEL. PMID:21660043

To analyze the initial thoracic involvement by CT in a consecutive series of patients with lymphoma. A retrospective analysis was made of thoracic CT studies made at the time of diagnosis of 259 patients with lymphoma. Mediastinal pulmonary, pleural, pericardial and chest wall involvement was assessed by CT. Of 259 patients (129 men y 130 women), 56 had Hodgkin's disease (HD) and 203 had non-Hodgkin lymphoma (NHL). Forty-two percent (42.5%, 110/259) of the patients had chest involvement on CT: 33 of 56 patients with HD (58.9%) and 77 of 203 patients with NHL (37.9%). All the patients with thoracic HD and 71.4% of patients with thoracic NHL, had mediastinal lymph node involvement. of the patients with thoracic involvement 12.1% (4/33) of the patient with HD and 23.3% (18/77) of the patients with NHL had pulmonary involvement. Thoracic involvement on CT was more frequent in HD. Mediastinal lymph node involvement was the most common finding fundamentally in HD. Pulmonary disease always occurred in the presence of mediastinal lymph node involvement in HD but could occur as an isolated finding in NHL. (Author) 24 refs.

ALCL can sometimes involve the bone marrow, and in advanced stages, it can produce destructive extranodal lesions. But anaplastic large cell lymphoma kinase (ALK+ ALCL with soft tissue involvement is very rare.Case report: A 35-year-old woman presented with waist pain for over 1 month. The biopsy of soft tissue lesions showed that these cells were positive for ALK-1, CD30, TIA-1, GranzymeB, CD4, CD8, and Ki67 (90%+ and negative for CD3, CD5, CD20, CD10, cytokeratin (CK, TdT, HMB-45, epithelial membrane antigen (EMA, and pan-CK, which identified ALCL. After six cycles of Hyper-CVAD/MA regimen, she achieved partial remission. Three months later, she died due to disease progression.Conclusion: This case illustrates the unusual presentation of ALCL in soft tissue with a bad response to chemotherapy. Because of the tendency for rapid progression, ALCL in young adults with extranodal lesions are often treated with high-grade chemotherapy, such as Hyper-CVAD/MA.

T-cell lymphoblastic lymphoma is a highly aggressive tumor derived from lymphocyte of the thymus, which accounts for 2% of non-Hodgkin's lymphoma. The disease occurs most commonly in adolescent and young adult males. It often results in respiratory emergency because of high proliferation rate. In this case, we confirmed the rapid progression of T-cell lymphoblastic lymphoma through the chest CT scan with one week interval. Three days of empirical chemotherapy resulted in substantial reduction of mediastinal mass, pleural thickening and pleural effusion.

Evaluation of Bone Marrow in 143 Lymphomas: The Relative Frequency and Pattern of Involvement, Secondary Myelopathies, Pitfalls and Diagnostic Validity

The aim of the present study is to assess the frequency of bone marrow (BM) involvement by both bone marrow aspirate and biopsy (BMA and BMB, respectively) procedures in established cases of lymphomas at initial presentation, and to study the relative frequency of marrow disease in relation to lymphoma types, patterns of infiltration and the 2ry associated changes, as well as the diagnostic challenges. Moreover, the diagnostic validity of BMA is tested taking the results of the BMB as the true test results, in order to determine the role of each procedure in the diagnostic approach of marrow infiltration. Patients and Method: This is a retrospective study carried out on 143 non consecutive Egyptian patients with lymphomas obtained from a private series during the years 2005 to 2008. Criteria of inclusion included the availability of full medical records and material (medical and pathological), patient consent, nodal disease with no therapy prior to BM sampling, except in 7 patients who had another 2nd BMB following therapy. BMA and BMB were performed as part of the routine workup for diagnosis and staging of lymphoma. The patients had a male to female sex ratio of 2.6:1 and a wide age range from 4 to 74 years. Results: In the present series, 64 cases out of the 143 lymphoma patients studied (44.8%) had a BM disease. Involvement was mostly bilateral (80%). Patients older than 40 years showed higher incidence of bone marrow involvement. There was complete concordance (100%) between both diagnostic procedures in the detection of 76 marrow disease-free lymphoma patients. BMA showed no false positive results and a low rate of deference that makes of it an ideal screening test. Three deferred smears of CLL for BMB diagnosis were all positive for involvement. However, in a total number of 64 BMB positive patients, aspirates could only identify lymphoma involvement in 42 lymphoma patients and missed 22 patients with a BM disease, with an overall sensitivity rate of 65

Primary effusion lymphoma (PEL) is a rare and aggressive non-Hodgkin's lymphoma. Human telomerase reverse transcriptase (hTERT), a key component responsible for the regulation of telomerase activity, plays important roles in cellular immortalization and cancer development. Triptolide purified from Tripterygium extracts displays a broad-spectrum bioactivity profile, including immunosuppressive, anti-inflammatory, and anti-tumor. In this study, it is investigated whether triptolide reduces hTERT expression and suppresses its activity in PEL cells. The mRNA and protein levels of hTERT were examined by real time-PCR and Western blotting, respectively. The activity of hTERT promoter was determined by Dual luciferase reporter assay. Our results demonstrated that triptolide decreased expression of hTERT at both mRNA and protein levels. Further gene sequence analysis indicated that the activity of hTERT promoter was suppressed by triptolide. Triptolide also reduced the half-time of hTERT. Additionally, triptolide inhibited the expression of transcription factor specificity protein 1(Sp1) in PEL cells. Furthermore, knock-down of Sp1 by using specific shRNAs resulted in down-regulation of hTERT transcription and protein expression levels. Inhibition of Sp1 by specific shRNAs enhanced triptolide-induced cell growth inhibition and apoptosis. Collectively, our results demonstrate that the inhibitory effect of triptolide on hTERT transcription is possibly mediated by inhibition of transcription factor Sp1 in PEL cells. - Highlights: • Triptolide reduces expression of hTERT by decreasing its transcription level. • Triptolide reduces promoter activity and stability of hTERT. • Triptolide down-regulates expression of Sp1. • Special Sp1 shRNAs inhibit transcription and protein expression of hTERT. • Triptolide and Sp1 shRNA2 induce cell proliferation inhibition and apoptosis.

The purpose of this study is to evaluate the diagnostic accuracy of CT in the differential diagnosis of tuberculous and malignant pleural effusion whether or not lung lesions are present, and to investigate the CT findings used for this differential diagnosis. This study involved 30 patients with tuberculous pleural effusion (mean age, 44.6 years; M : F = 19:11) and 20 with malignant pleural effusion (mean age, 57.2 years; M: F=10:10). All 50 patients underwent enhanced CT chest scans, and the respective conditions were pathologically confirmed. Two radiologists unaware of the pathologic results and distributions of patients reviewed these scans, CT findings of pleural effusions, their diagnoses, and the degree of confidence of their diagnoses. In most cases, CT provided correct differential diagnosis between tuberculous and malignant pleural effusion. It can help determine the nature of associated lung and pleural lesions, and specific findings of the latter, and can accurately differentiate tuberculous and malignant pleural effusion.

Primary pulmonary lymphoma mimicking a refractory lung abscess: A case report.

Science.gov (United States)

Matsumoto, Takeshi; Otsuka, Kojiro; Funayama, Yuki; Imai, Yukihiro; Tomii, Keisuke

2015-04-01

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.

Full Text Available BACKGROUND Malignant pleural effusions are a common cause of morbidity in patients with advanced cancers. Common malignancies associated with malignant pleural effusion include lung, breast and lymphomas. Diagnostic methods include cytological analysis and pleural biopsy either closed or thoracoscopic guided. This study was taken up to analyse the cancers associated with malignant pleural effusions and the diagnostic modalities employed towards the diagnosis of malignant pleural effusion. MATERIALS AND METHODS Retrospective analysis of case records of patients diagnosed as malignant pleural effusion prior to the use of thoracoscopicguided pleural biopsy during a two year period was done and the results were analysed to assess the causes of malignant pleural effusion and the diagnostic methods employed to confirm the diagnosis of malignant pleural effusion. RESULTS 48 cases of malignant pleural effusion were identified during the study period. The commonest malignancies associated with malignant pleural effusion were lung and breast cancer. Most of the patients were elderly, but some of the cases were identified in younger age groups especially in breast cancer. Cytological analysis and closed pleural biopsies were the diagnostic methods employed for diagnosing malignant pleural effusion. CONCLUSION The study results were consistent with published data that malignant pleural effusions were commonly associated with lung and breast malignancies. Most of the malignancies were in patients aged more than 50 years, but some cases in younger age group especially associated with breast malignancy were noted. Cytology and closed pleural biopsy are adequate to diagnose malignant pleural effusion even in absence of thoracoscopy.

Pneumonia due to Rhodococcus equi in a non-Hodgkin's lymphoma patient: case report

Full Text Available Extranodal MALT lymphomas are a type of lymphoproliferative syndrome belonging to non-Hodgkin's lymphomas. The most common affectation of these types of lymphomas is the digestive tract (80%, the lung being only 14% of cases. We present the case of a 73 years old woman who goes to progressive dyspnea, with a large right pleural effusion on the chest x-ray. After screening and differential diagnosis of the different types of pleural effusion and the clinical etiological processes involved in its production, the diagnosis of lymphoproliferative process was reached, starting chemotherapy treatment with good evolution of both the pleural effusion and the patient's clinic.

In an attempt to evaluate characteristic CT features of primary pancreatic involvement in non-Hodgkin lymphoma (NHL), scans of 10 patients were reviewed retrospectively and compared to 50 patients with histologically proved different neoplasms of the pancreas. Setting the correct diagnosis of NHL would be essential for planning of treatment and prognosis. CT findings of NHL were characteristic but not specific. Nevertheless, the presence of a homogeneous pancreatic mass with a diameter of 7 cm or more, infiltrating surrounding tissue accompanied by retroperitoneal and/or mesenteric lymphadenopathy strongly suggests NHL. CT-guided needle biopsy can help to establish the diagnosis of pancreatic NHL. (orig.)

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

Epidural involvement is rarely associated with lymphoma, it being more typical of non-Hodgkin`s lymphoma in advanced stages of the disease. The invasion of the epidural space is usually caused by the extension of a paravertebral mass or by the affected vertebrae. However, the epidural space alone can be involved. We present a case of epidural lymphoma in a patient who presented with clinical evidence of spinal cord compression. Magnetic resonance disclosed the existence of an epidural mass compressing and displacing the spinal cord without involving the adjacent vertebra or the associated paravertebral mass.

Lymphoma is the most common hematologic malignancy and represents approximately 5.3% of all cancers. The World Health Organization published a revised classification scheme in 2008 that groups lymphomas by cell type and molecular, cytogenetic, and phenotypic characteristics. Most lymphomas affect the thorax at some stage during the course of the disease. Affected structures within the chest may include the lungs, mediastinum, pleura, and chest wall, and lymphomas may originate from these sites as primary malignancies or secondarily involve these structures after arising from other intrathoracic or extrathoracic sources. Pulmonary lymphomas are classified into one of four types: primary pulmonary lymphoma, secondary pulmonary lymphoma, acquired immunodeficiency syndrome-related lymphoma, and post-transplantation lymphoproliferative disorders. Although pulmonary lymphomas may produce a myriad of diverse findings within the lungs, specific individual features or combinations of features can be used, in combination with secondary manifestations of the disease such as involvement of the mediastinum, pleura, and chest wall, to narrow the differential diagnosis. While findings of thoracic lymphoma may be evident on chest radiography, computed tomography has traditionally been the imaging modality used to evaluate the disease and effectively demonstrates the extent of intrathoracic involvement and the presence and extent of extrathoracic spread. However, additional modalities such as magnetic resonance imaging of the thorax and {sup 18}F-FDG PET/CT have emerged in recent years and are complementary to CT in the evaluation of patients with lymphoma. Thoracic MRI is useful in assessing vascular, cardiac, and chest wall involvement, and PET/CT is more accurate in the overall staging of lymphoma than CT and can be used to evaluate treatment response.

Primary effusion lymphoma (PEL) is a rare and highly aggressive B-cell malignancy with Kaposi's sarcoma-associated herpesvirus (KSHV) infection, while lack of effective therapies. Our recent data indicated that targeting the sphingolipid metabolism by either sphingosine kinase inhibitor or exogenous ceramide species induces PEL cell apoptosis and suppresses tumor progression in vivo. However, the underlying mechanisms for these exogenous ceramides "killing" PEL cells remain largely unknown. Based on the microarray analysis, we found that exogenous dhC16-Cer treatment affected the expression of many cellular genes with important functions within PEL cells such as regulation of cell cycle, cell survival/proliferation, and apoptosis/anti-apoptosis. Interestingly, we found that a subset of tumor suppressor genes (TSGs) was up-regulated from dhC16-Cer treated PEL cells. One of these elevated TSGs, Thrombospondin-1 (THBS1) was required for dhC16-Cer induced PEL cell cycle arrest. Moreover, dhC16-Cer up-regulation of THBS1 was through the suppression of multiple KSHV microRNAs expression. Our data demonstrate that exogenous ceramides display anti-cancer activities for PEL through regulation of both host and oncogenic virus factors.

Lymphomas involving Waldeyer's ring: placement, paradigms, peculiarities, pitfalls, patterns and postulates.

Science.gov (United States)

Tan, L H

2004-07-01

This review revisits Waldeyer's ring lymphomas as classified by the World Health Organisation. Sources of data include international studies on Waldeyer's ring lymphomas as well as from personal observations gleaned from lymphoma statistics of Singapore General Hospital, Changi General Hospital, Tan Tock Seng Hospital and National University Hospital within the last decade or so. Waldeyer's ring shares many of the histopathological trends of the rest of mucosa-associated lymphoid tissue (MALT), such as the high frequency of diffuse large B-cell lymphomas, and the relative rarity of follicular lymphomas in spite of its rich endowment with reactive lymphoid follicles. However, extranodal marginal zone lymphoma or "MALToma" may not be as frequently encountered as in other mucosal sites. Furthermore, the placement of Waldeyer's ring is unique in that stark comparisons with the lymphopathology of the immediately anterior oronasal cavities can be made, with intriguing peculiarities such as the abrupt reversal of the ratio of B-cell to T/NK-cell lymphoma frequency upon crossing the imaginary line that separates the 2 regions. The differential diagnosis with regionally common lymphoma mimics, in particular reactive parafollicular hyperplasia and nasopharyngeal undifferentiated (lymphoepithelial) carcinoma of Schmincke pattern, both often aetiologically related to Epstein-Barr viral infection, is also discussed. Recognition of the peculiarities and patterns of Waldeyer's ring lymphomas is important for accurate pathologic assessment. Postulates that attempt to account for the patterns and peculiarities of Waldeyer's ring lymphopathology can be used to direct further research.

CARDIAC LYMPHOMA IN DOG

Full Text Available Lymphoma is a lymphoid tumor that originates in hematopoietic organs such as lymph node, spleen or liver. In dogs, the overall prevalence of cardiac tumors was estimated to be only 0.19% based on the results of the survey of a large database, and lymphomas accounts for approximately 2% of all cardiac tumors. In general, the involvement of the myocardium is rarely described in canine lymphoma. Currently, there is no evidence of a viral association with primary cardiac lymphoma in dogs, but other types of immunosuppression may contribute to abnormal events, such as involvement primary cardiac. The aim of this study was to analyze a case of sudden death of a bitch, SRD, aged 10, who had the final diagnosis of cardiac lymphoma.

Objective To investigate the relationship among angiogenic cytokines, fibrinolytic activity and effusion size in parapneumonic effusion (PPE) and their clinical importance. Methods From January 2008 through December 2010, 26 uncomplicated (UPPE) and 38 complicated (CPPE) PPE were studied. Based on chest ultrasonography, there were non-loculated in 30, uni-loculated in 12, and multi-loculated effusions in 22 patients. The effusion size radiological scores, and effusion vascular endothelial growth factor (VEGF), interleukin (IL)-8, plasminogen activator inhibitor type-1 (PAI-1) and tissue type plasminogen activator (tPA) were measured on admission. Treatment outcome and pleural fibrosis, defined as radiological residual pleural thickening (RPT), were assessed at 6-month follow-up. Results The effusion size and effusion VEGF, IL-8 and PAI-1/tPA ratio were significantly higher in CPPE than in UPPE, and significantly higher in multi-loculated PPE than in non-locualted and uni-loculated PPE, respectively. VEGF (cutoff value 1975 pg/ml) and IL-8 (cutoff value 1937 pg/ml) seemed best to discriminate between UPPE and CPPE. VEGF, IL-8 and effusion size correlated positively with PAI-1/tPA ratio in both UPPE and CPPE. Moreover, the level of VEGF, but not IL-8, correlated positively with effusion size in all patients (r = 0.79, peffusion were prone to have medical treatment failure (n = 10; VEGF, odds ratio 1.01, p = 0.02; effusion size, odds ratio 1.26, p = 0.01). Additionally, ten patients with RPT had larger effusion size and higher levels of VEGF and PAI-1/tPA ratio than did those without. Conclusions In PPE, VEGF and IL-8 levels are valuable to identify CPPE, and higher VEGF level or larger effusion is associated with decreased fibrinolytic activity, development of pleural loculation and fibrosis, and higher risk of medical treatment failure.

The purpose of this paper is to retrospectively evaluate CT and MR findings of central nervous system (CNS) involvement of leukemia and systemic lymphoma in children. Over a 12-year period, sixty-five patients with leukemia and fifteen patients with systemic lymphoma underwent cerebral CT and/or MR imaging. Nine patients were diagnosed as CNS involvement of leukemia and lymphoma. The CT and MR abnormalities in these patients were correlated with the findings of histology, cerebrospinal fluid cytology, and/or treatment. The age of the patients ranged from 0 to 15 years old. They consisted of 6 boys and 3 girls. The CT examinations were performed before and after contrast administration. MR examinations were performed on a 1.5-T unit, and T1-weighted, T2-weighted, and proton density-weighted images were obtained using spin-echo or fast spin-echo sequences. Tumor masses were present in seven with leukemia, and in two with malignant lymphoma. On the CT scan, tumor masses were hyperdense with contrast enhancement. On the MR images, their signals were variable. In all of nine patients, tumor masses were contiguous with a meningeal surface. Postcontrast T1-weighted images were valuable in demonstrating meningeal infiltration. Tumoral hemorrhage was found in two patients. In a patient with tumor at the superior sagittal sinus, venous infarct was observed. CNS leukemic and lymphomatous masses are almost hyperdense on the CT and they are characteristically contiguous with a meningeal surface. MR imaging was valuable in demonstrating meningeal infiltration. (K.H.)

Meigs' syndrome is defined as the presence of a benign ovarian tumor with pleural effusion and ascites that resolve after removal of the tumor. The pathogenesis of the production of ascites and pleural effusion in this syndrome remains unknown. Aside from pleural effusion and ascites, pericardial effusion is rarely observed in Meigs' syndrome. Here, we report the first case of Meigs' syndrome with preceding pericardial effusion in advance of pleural effusion. An 84-year-old Japanese non-smoking woman with a history of lung cancer, treated by surgery, was admitted due to gradual worsening of dyspnea that had occurred over the previous month. She had asymptomatic and unchanging pericardial effusion and a pelvic mass, which had been detected 3 and 11 years previously, respectively. The patient was radiologically followed-up without the need for treatment. Two months before admission, the patient underwent a right upper lobectomy for localized lung adenocarcinoma and intraoperative pericardial fenestration confirmed that the pericardial effusion was not malignant. However, she began to experience dyspnea on exertion leading to admission. A chest, abdomen, and pelvis computed tomography scan confirmed the presence of right-sided pleural and pericardial effusion and ascites with a left ovarian mass. Repeated thoracentesis produced cultures that were negative for any microorganism and no malignant cells were detected in the pleural effusions. Pleural fluid accumulation persisted despite a tube thoracostomy for pleural effusion drainage. With a suspicion of Meigs' syndrome, the patient underwent surgical resection of the ovarian mass and histopathological examination of the resected mass showed ovarian fibroma. Pleural and pericardial effusion as well as ascites resolved after tumor resection, confirming a diagnosis of Meigs' syndrome. This clinical course suggests a strong association between pericardial effusion and ovarian fibroma, as well as pleural and peritoneal

Pseudochylothorax is a very rare form of pleural effusion. It is also called chyliform or cholesterol pleural effusion. It is usually a unilateral process and approximately one-third of patients are asymptomatic at presentation. We report a case of a 60 year old man with a background of rheumatoid arthritis who presented with progressive dyspnea. Chest X-ray revealed a new left pleural effusion and a small persistent right pleural effusion. He presented 5 years prior due to recurrent pleural effusion and no diagnosis was made. Repeat thoracentesis yielded 350 milliliters of thick, milky, tan-colored fluid.

Primary testicular lymphoma (PTL) a relatively rare disease of non-Hodgkin's lymphomas occurring with a lesser incidence of 1-2% has a propensity to occur at later ages above 50 years. PTL spreads to extra nodal sites due to deficiency of extra cellular adhesion molecules. We present detection of multiple sites of extra nodal involvement of PTL by F-18 positron emission tomography/computed tomography study aiding early detection of the dissemination thus aiding in staging and management.

How I treat double-hit lymphoma.

Science.gov (United States)

Friedberg, Jonathan W

2017-08-03

The 2016 revision of the World Health Organization (WHO) classification for lymphoma has included a new category of lymphoma, separate from diffuse large B-cell lymphoma, termed high-grade B-cell lymphoma with translocations involving myc and bcl-2 or bcl-6 . These lymphomas, which occur in hit lymphomas (or triple-hit lymphomas if all 3 rearrangements are present). It is important to differentiate these lymphomas from the larger group of double-expressor lymphomas, which have increased expression of MYC and BCL-2 and/or BCL-6 by immunohistochemistry, by using variable cutoff percentages to define positivity. Patients with double-hit lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of central nervous system involvement and progression. Double-hit lymphomas may arise as a consequence of the transformation of the underlying indolent lymphoma. There are no published prospective trials in double-hit lymphoma, however retrospective studies strongly suggest that aggressive induction regimens may confer a superior outcome. In this article, I review my approach to the evaluation and treatment of double-hit lymphoma, with an eye toward future clinical trials incorporating rational targeted agents into the therapeutic armamentarium. © 2017 by The American Society of Hematology.

He denied any chest pain, and reported his shortness of breath was worse with exertion and lying flat. Significant findings: Chest x-ray and bedside ultrasound revealed a large right pleural effusion, estimated to be greater than two and a half liters in size. Discussion: The incidence of pleural effusion is estimated to be at least 1.5 million cases annually in the United States.1 Erect posteroanterior and lateral chest radiography remains the mainstay for diagnosis of a pleural effusion; on upright chest radiography small effusions (>400cc will blunt the costophrenic angles, and as the size of an effusion grows it will begin to obscure the hemidiphragm.1 Large effusions will cause mediastinal shift away from the affected side (seen in effusions >1000cc.1 Lateral decubitus chest radiography can detect effusions greater than 50cc.1 Ultrasonography can help differentiate large pulmonary masses from effusions and can be instrumental in guiding thoracentesis.1 The patient above was comfortable at rest and was admitted for a non-emergent thoracentesis. The pulmonology team removed 2500cc of fluid, and unfortunately the patient subsequently developed re-expansion pulmonary edema and pneumothorax ex-vacuo. It is generally recommended that no more than 1500cc be removed to minimize the risk of re-expansion pulmonary edema.2

Differentiation of subdural effusions

Although X-ray computerized tomography facilitates the diagnosis of intracranial disorders, differentiation of the lesions like extracerebral effusions is often unsatisfactory. Epidural and acute subdural haematoma shown as hyperdensity in CT requires an emergency neurosurgical operation, so that differentiation of these hyperdense effusions may not be required. But the discrimination of the effusions shown as hypodensity in CT (chronic subdural haematoma, subdural hygroma, subdural empyema as well as arachnoid cysts) is urgent because of the different treatment of these effusions. The clinical differentiation is hampered by unspecific neurologic symptoms and the lack of adequate laboratory tests. Some aspects facilitating the diagnostic decision are presented. Recent magnetic resonance (MR) studies promise further progress in differentiating between subdural effusions. (orig.) [de

In order to evaluate the possible role of MRI in detecting lymphomatous marrow involvement, a MRI examination was performed in newly diagnosed patients with Hodgkin's disease (HD) and nonHodgkin lymphoma (NHL). From this the authors concluded that MRI should not be used as a replacement for bone marrow biopsies in HD and NHL, but rather as a complementary tool utilizing the panoramic view offered by MRI which permit to disclose focal areas of bone involvement different from the sacrum, thus not valuable with routine biopsies.

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

Human T-cell lymphotropic virus type 1 is associated with adult T-cell leukemia/lymphoma (ATLL). Published series of ATLLs seen at a United States medical institution are rare. We present the features of 4 ATLLs diagnosed at our North American tertiary care medical center from 1990 to 2012. Despite the absence of a history of origin from an endemic region, all our ATLLs demonstrated evidence of human T-cell lymphotropic virus type 1 infection. Central nervous system (CNS) involvement by ATLL was uncommon in our series, and represented only 1.6% (1/64) of all CNS B-cell or T-cell lymphomas diagnosed over a 20+ year period at our institution. Review of the medical literature reveals that the majority of CNS-involved ATLLs present with the lymphoma or acute subtype, and complete remission is difficult to achieve in these cases. CNS involvement frequently occurs with a systemic disease, which carries an aggressive clinical course with poor prognosis. In addition, CNS involvement by ATLL can be the initial presentation or seen with relapsed disease, can be the only site or be associated with other tissue sites of involvement, and may manifest with variable clinical signs/symptoms. Our retrospective study reveals that ATLLs are rare mature T-cell lymphomas in a native North American population, but the clinical and histopathologic features of ATLLs from this nonendemic region are similar to those seen from other endemic regions. Early recognition of these rare ATLLs involving uncommon sites, such as the CNS, will help optimize treatment for these infrequent mature T-cell lymphomas.

Diagnostic Tools of Pleural Effusion

Science.gov (United States)

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: Recently, involved-site radiation therapy (ISRT) guidelines have been developed and published to replace the previous concept of involved-field radiation therapy for patients with lymphoma. However, these ISRT guidelines may be interpreted in different ways, posing difficulties for prospective clinical trials. This study reports survey results regarding interpretation of the ISRT guidelines. Methods and Materials: Forty-four expert lymphoma radiation oncologists were asked to participate in a survey that included 7 different cases associated with 9 questions. The questions pertained to ISRT contouring and asked respondents to choose between 2 different answers (no “correct” answer) and a third write-in option allowed. Results: Fifty-two percent of those surveyed responded to the questionnaire. Among those who responded, 72% have practiced for >10 years, 46% have treated >20 Hodgkin lymphoma cases annually, and 100% were familiar with the ISRT concept. Among the 9 questions associated with the 7 cases, 3 had concordance among the expert radiation oncologists of greater than 70%. Six of the questions had less than 70% concordance (range, 56%-67%). Conclusions: Even among expert radiation oncologists, interpretation of ISRT guidelines is variable. Further guidance for ISRT field design will be needed to reduce variability among practicing physicians.

We attempt to correlate the histological types [in three cases of B-cell non-Hodgkin's lymphoma (NHL), one case of T-cell NHL and one of Hodgkin's disease] with the radiological presentation and compare our findings with the literature reviewed. Among the mammographic studies, performed over and 18-month period, we have assessed five patients (four women and one man, aged as having lymphoma. the man presented bilateral involvement. Both mammography and a broader study with ultrasound and chest and abdominal CT scan were performed in every case. Four patients underwent breast ultrasound. The definitive diagnosis was based on biopsy in all cases. Three of the five cases involved primary lymphomas and the other two were secondary. Four patients presented NHL and the remaining patient had Hodgkin's disease. In mammography, the nodules showed different degrees of margin definition. In ultrasound, all the lesion were hypoechoic. The radiological diagnosis of breast lymphoma is difficult in the absence of a previous diagnosis of lymphoma. This lesion should be included in the differential diagnosis in the presence of a breast nodule associated with axillary lymph nodes, especially when the latter are bilateral. (Author)

Purpose: Nodular lymphocyte predominance Hodgkin's lymphoma is a very rare disease, characterized by an indolent clinical course, with sometimes very late relapses occurring in a minority of all patients. Considerable discussion is ongoing on the treatment of primary and relapsed disease. Patients and Methods: A group of 9 patients were irradiated to a dose of 4 Gy on involved areas only. Results: After a median follow-up of 37 months (range, 6-66), the overall response rate was 89%. Six patients had complete remission (67%), two had partial remission (22%), and one had stable disease (11%). Of 8 patients, 5 developed local relapse 9-57 months after radiotherapy. No toxicity was noted. Conclusion: In nodular lymphocyte predominance Hodgkin's lymphoma, low-dose radiotherapy provided excellent response rates and lasting remissions without significant toxicity.

A case of recurrent pleural effusion: Can we think beyond tuberculosis and malignancy?

Directory of Open Access Journals (Sweden)

Bhumika Vaishnav

2014-01-01

Full Text Available Pleural effusion can occur due to a variety of causes such as infectious, neoplastic, inflammatory, autoimmune, traumatic, etc. Recurrent pleural effusions have always been a diagnostic challenge. Here, we present a case of recurrent exudative pleural effusion in a male patient, which was the first clinical manifestation of rheumatoid arthritis. Of note was the absence of articular involvement at the onset of the disease. The low glucose concentration, low pH and low C4 level in the pleural fluid were the most valuable findings to distinguish it from tuberculous and malignant pleural effusions. Pleural biopsy also helped in making such a distinction. Thus, in a patient with recurrent pleural effusion, rheumatoid etiology should also be kept in mind as a differential diagnosis.

Therapy of non-Hodgkin's lymphoma

Non-Hodgkin's lymphomas are a heterogeneous group of malignancies of the lymphoid system. The exact etiology for most lymphomas has not been determined, but both viral and bacterial infections have been shown to be important etiologic factors. The WHO classification of hematopoietic and lymphoid tumours classifies lymphomas into B-cell and T-cell neoplasms. B-cell lymphomas account for more than 85% of all lymphomas. The Ann Arbor staging classification has been adopted by the AJCC and UICC as a standard for classifying extent of anatomic disease. The two most common histologic disease entities are follicular lymphomas and diffuse large B-cell lymphomas. The management of follicular lymphomas is used as a paradigm for the management of all indolent lymphomas. Radiation therapy is used for stage I and II disease, while alkylating agent chemotherapy, immunotherapy and radioimmunotherapy are most frequently used in stage III and IV disease that requires treatment. Most patients with follicular lymphoma enjoy prolonged survival, but at present there is no evidence that those with stage III and IV follicular lymphoma can be cured. Diffuse large B-cell lymphomas serve as a paradigm for treating aggressive lymphomas. Stage I and II diffuse large cell lymphomas are generally treated with combined modality therapy with doxorubicin-based chemotherapy followed by involved field radiation therapy, while those with stage III and IV disease are treated with chemotherapy alone. Patients who fail initial management are treated with further chemotherapy. High-dose chemotherapy with stem cell rescue has been shown to be particularly effective as salvage treatment for diffuse large cell lymphomas. The management of a heterogeneous group of primary extranodal lymphomas in general follows the above treatment principles, with additional treatment being required for those with a high risk of CNS failures, or involvement of contralateral paired organs.

The incorporation of rituximab in immunochemotherapy has improved treatment outcomes for diffuse large B-cell lymphoma, but the prognosis for some diffuse large B-cell lymphomas remains dismal. Identification of adverse prognostic subgroups is essential for the choice of appropriate therapeutic strategy. We retrospectively investigated the impact of so-called 'double-hit' cytogenetic abnormalities, i.e. cytogenetic abnormalities involving c-MYC co-existing with other poor prognostic cytogenetic abnormalities involving BCL2, BCL6 or BACH2, on treatment outcomes for 93 consecutive diffuse large B-cell lymphoma patients. According to the revised international prognostic index, no patients were cytogenetically diagnosed with double-hit lymphomas in the 'very good' risk group or in the 'good' risk group, while 5 of 33 patients had double-hit lymphomas in the 'poor' risk group. All the double-hit lymphoma patients possessed both nodal and extranodal involvement. The overall complete response rate was 89.3%, overall survival 87.1% and progression-free survival 75.8% over 2 years (median observation period: 644 days). The complete response rates were 93.2% for the non-double-hit lymphoma patients and 40.0% for the double-hit lymphoma patients. Significantly longer progression-free survival and overall survival were observed for the 'very good' and the 'good' risk patients than for the 'poor' risk patients. Moreover, the progression-free survival of double-hit lymphoma was significantly shorter than that of the non-double-hit lymphoma 'poor' risk patients (P = 0.016). In addition, the overall survival of the double-hit lymphoma patients also tended to be shorter than that of the non-double-hit lymphoma 'poor' risk group. The diagnosis of double-hit lymphoma can help discriminate a subgroup of highly aggressive diffuse large B-cell lymphomas and indicate the need for the development of novel therapeutic strategies for double-hit lymphoma.

Full Text Available Abstract Background Cells with "hand mirror" morphology have not, to the best of our knowledge, been described in a primary effusion sample. This paper describes a case of T-cell lymphoma with eosinophilia in a patient with suspected peritoneal carcinomatosis. Rarely, a T-cell lymphoproliferative process may mimic primary peritoneal carcinomatosis, clinically suggested by a presentation in CT imaging of omental caking with bilateral massive loculated effusions in a patient without lymphadenopathy or splenomegaly. Methods A 60 year old caucasian male presented with vague abdominal discomfort and increasing abdominal girth. Computed tomography showed a two centimeter thick omental cake and a small loculated effusion. The clinical presentation and imaging findings were most consistent with peritoneal carcinomatosis. Cytologic evaluation of the effusion was undertaken for diagnostic study. Results Rapid intraprocedural interpretation of the effusion sample showed a monomorphic population of cells with "hand-mirror" cell morphology exhibiting cytoplasmic extensions (uropodia with 3–5 course dark cytoplasmic granules and a rim of vacuolated cytoplasm capping the opposing "mirror head" side. These cells were seen within a background of mature eosinophils. Flow cytometric evaluation of the ascites fluid demonstrated an atypical T-cell population with the following immunophenotype: CD2-, CD3+, CD4-, CD5-, CD7-, CD8+, CD56+. T-cell receptor (TCR gene rearrangement was positive for clonal TCR-gamma gene rearrangement, supporting the diagnosis of a T-lymphoprolifereative disorder. Conclusion A T-cell lymphoproliferative process may present with "hand mirror" morphology in an effusion sample. These cells may show polar cytoplasmic vacuolization and 3–5 course granules within the "handle" of these unique cells. Cytoplasm shows peripheral constriction around the nucleus.

The posterior pararenal space(PPS) is a potential space between the posterior renal fascia and the transversalis fascia. We reviewed 12 cases of posterior pararenal effusion. The causes of the effusion were retroperitoneal hemorrhage due to trauma(7 cases) or rupture of renal tumor(1 case), pancreatitis(2 cases), urinoma (1 case) and amebic colitis of the cecum(1 case). The CT findings of the effusion were semilunar fluid density in the dependant portion of the PPS(9/12), partial obliteration of the PPS extending to the flank stripe(2/12), and total obliteration of the PPS extending to the anterior abdominal wall(1/12). The effusion in the ipsilateral perirenal space and thickening of the ipsilateral posterior renal fascia were combined in all cases. The effusion in the ipsilateral anterior pararenal space was associated in 11 cases of 12. The effusion in the PPS is not uncommon findings of retroperitoneal hemorrhage or effusion, but usually related with perirenal or anterior pararenal effusion with no clinical significance

Biofilms have been implicated in the development of several chronic upper respiratory tract infections. Role of bacterial biofilms has been well studied in the pathogenesis of chronic rhinosinusitis. However, its impact on development of middle ear effusion is still a matter of debate. To study the extent of surface adenoid biofilm and evaluate its role in the pathogenesis of chronic otitis media with effusion in children. The study was carried out on 40 children in Alexandria Main University Hospital between 1 and 16 years of age without sex predilection, who were divided into two groups. The first group (20 children) had otitis media with effusion associated with adenoid hypertrophy, whereas the second group (20 children) had adenoid hypertrophy without middle ear effusion. Adenoidectomy with ventilation tube insertion was done for group 1 cases, whereas, only Adenoidectomy was done for group 2 cases. The samples were processed for the detection of biofilms by scanning electron microscopy. The biofilm formation was graded according to extension. Biofilm formation was detected on all samples for group 1. Adenoids removed from patients with otitis media with effusion had higher-grade biofilm formation than the other group (P 0.0001). No correlation was found between adenoid size and biofilm formation. In pediatric population, adenoid surface biofilm formation may be involved in the pathogenesis otitis media with effusion.

Full Text Available Burkitt's lymphoma is an extremely aggressive B-cell non-Hodgkin lymphoma. Patients with the sporadic form of Burkitt's lymphoma typically present with a rapidly growing abdominal mass, pain and distension. Involvement of either the appendix and/or ovaries in females is a rare manifestation of the disease. We present an unusual case of a 13 year old girl with appendiceal and ovarian Burkitt's lymphoma presenting with signs of acute appendicitis. This case demonstrates the potential for secondary involvement of the appendix and/or ovaries from Burkitt's lymphoma as well as the importance of the histopathology.

1987-01-01

In most human lymphomas, the chromosome translocation t(14;18) occurs within two breakpoint clustering regions on chromosome 18, the major one at the 3' untranslated region of the bcl-2 gene and the minor one at 3' of the gene. Analysis of a panel of follicular lymphoma DNAs using probes for the first exon of the bcl-2 gene indicates that DNA rearrangements may also occur 5' to the involved bcl-2 gene. In this case the IgH locus and the bcl-2 gene are found in an order suggesting that an inversion also occurred during the translocation process. The coding region of the bcl-2 gene, however, are left intact in all cases of follicular lymphoma studied to date

67 Ga imaging of non-Hodgkin's lymphoma is useful for evaluating the presence of viable tumour in a residual mass after treatment. However, we have frequently seen gallium uptake in the pulmonary hila without other evidence of lymphoma. To study the significance of this finding, 79 patients with intermediate grade non-Hodgkin's lymphoma were reviewed. Thirty-seven (47%) had abnormal hilar gallium uptake. Twenty-three of these could be fully evaluated, and only five (22%) had hilar lymphoma. A pattern of bilateral, symmetric hilar uptake was seen in 19 patients, but only one had evidence of lymphoma. In 15 cases, this pattern was seen only on single photon emission computed tomography (SPECT). The aetiology of this uptake remains unknown. It is not treatment related, as 12 patients had hilar gallium uptake prior to chemotherapy. Unless confirmed by other methods, hilar gallium uptake should not be attributed to lymphoma, and should not influence patient management. (Author)

Objective: To describe the general findings of lymphoma and their histological patterns in patients less than 20 years old. Materials And Methods: Twenty-two cases (16 male and 6 female, mean age 11.5 years) from the digital archive of computed tomography at the Cancer Control Center of Hospital Universitario Pedro Ernesto - Universidade do Estado do Rio de Janeiro, Rio de Janeiro, RJ, Brazil, were retrospectively analyzed in the period between March 2003 and July 2005. Of these 22 cases, 12 were Hodgkin's and 10 were non-Hodgkin's. Results: Overall, mediastinal lymphadenomegaly was the most frequent finding (59%), with predominance in the Hodgkin's subgroup (75%), followed by hepatosplenomegaly (50%) and cervical and retroperitoneal lymphadenomegaly (27.3%). The Hodgkin's subgroup presented a prevalence of lymphadenopathy, in many lymph node chains, followed by hepatosplenomegaly (50%). One case was found with unilateral tonsillar mass, pulmonary ground-glass opacities, and renal nodules. In the non-Hodgkin's subgroup, the disease was predominantly extranodal, characterized by hepatosplenomegaly (50%), thickening of the intestinal wall (40%), pleural effusion (30%), pulmonary nodule (20%), ascites (10%), pericardial effusion (10%) and mixed bone lesions (10%). Conclusion: Computed tomography is an extremely useful method for detection, staging and follow-up of lymphomas, with alert findings like mediastinal lymphadenopathy, hepatosplenomegaly, unilateral tonsillar mass and thickening of intestinal wall.

Purpose: To develop easily applicable guidelines for the determination of initially involved lymph nodes to be included in the radiation fields. Patients and methods: Patients with supra-diaphragmatic Hodgkin lymphoma. All the imaging procedures were carried out with patients in the treatment position. The prechemotherapy PET/CT was coregistered with the postchemotherapy CT simulation for planning purposes. Initially involved lymph nodes were determined on fused prechemotherapy CT and FDG-PET imaging data. The initial assessment was verified with the postchemotherapy CT scan. Results: The classic guidelines for determining the involvement of lymph nodes were not easily applicable and did not seem to reflect the exact extent of Hodgkin lymphoma. Three simple steps were used to pinpoint involved lymph nodes. First, FDG-PET scans were meticulously analysed to detect lymph nodes that were overlooked on CT imaging. Second, any morphological and/or functional asymmetry was sought on CT and FDG-PET scans. Third, a decrease in size or the disappearance of initially visible lymph nodes on the prechemotherapy CT scan as compared to the postchemotherapy CT scan was considered as surrogate proof of initial involvement. Conclusions: All the radiological procedures should be performed on patients in the treatment position for proper coregistration. It is highly advisable that all CT and/or CT/PET scans be performed with IV contrast. Using the above-mentioned three simple guidelines, initially involved lymph nodes can be detected with very satisfactory accuracy. It is also emphasized that the classic guidelines (2, 3, 4) can always be used when deemed necessary

IL-35 is a novel anti-inflammatory and immunosuppressive cytokine primarily produced by Treg cells, and is involved in inflammatory diseases and autoimmune diseases. However, its roles in tuberculous pleural effusion (TPE) remain unknown. We aimed to investigate the potential involvement of IL-35 in TPE. Thirty TPE patients and 20 lung cancer patients with malignant pleural effusion (MPE) were recruited. Samples of pleural effusion (100 mL) were collected after traditional pleurocentesis. Blood was sampled from TPE patients. Mononuclear cells were isolated by Ficoll-Hypaque gradient. Proportions of Th1, Th17, and IL-35-producing cells were analyzed by flow cytometry. IL-35 was assessed by real-time RT-PCR, ELISA, and immunofluorescence. An ELISPOT assay was used to assess the effect of IL-35 on pleural effusion mononuclear cells (PEMCs). Proportions of IL-35-producing cells were higher in TPE compared with MPE (49.4±6.0 vs. 15.8±5.4%, Ppleural tissues from TPE patients. Results suggest that there is an imbalance in IL-35 metabolism in TPE. However, further studies are required to assess the exact relationship with the immune system response to tuberculosis. IL-35 might play a role in TPE and might be targeted as a treatment for TPE.

Pleural effusion (PE) is a very uncommon manifestation of sarcoidosis. It is equally observed in men and women, can appear at any age and in all radiologic stages, though it is more common in stages i and ii. Effusions have usually a mild or medium size and mainly involve the right side. Various mechanisms can be implicated. PE will be a serous exudate if there is an increase in the capillary permeability due to direct involvement of the pleural membrane, a chylothorax if mediastinum lymph nodes compress the thoracic duct and/or the lymphatic drainage from the pleural cavity, an hemothorax if granuloma compress or invade pleural small vessels or capillaries, and even a transudate if there is compression of the inferior vena cava, atelectasis due to complete bronchial obstruction or when the resolution of the PE is incomplete with chronic thickening of visceral pleura (trapped lung). It manifests biochemically as a pauci-cellular exudate with a predominance of lymphocytes, though there can be a preponderance of eosinophils or neutrophils. Protein concentrations are usually proportionately higher than lactate dehidrogenase, adenosine deaminase is normally low and it is possible to find increased levels of CA-125 in women. The tuberculin test is negative and pleural or lung biopsies yield the diagnosis by confirming the presence of non-caseating granulomata. These PE can have a favorable self-limited outcome, even though in most cases treatment with corticosteroids is needed, while surgery is required in a few cases.

Chronic otitis media with effusion (OME) is associated with irreversible changes in the middle ear, sometimes leading to hearing loss and abnormal language development in children. While the pathogenesis of OME is not fully understood, inflammatory and allergic factors are thought to be involved. The study aimed to investigate the role of cytokines in the local development of chronic OME, and assess differences in the cytokine profiles between atopic and non-atopic children. 84 atopic and non-atopic children with chronic OME (mean age of 6 years 7 months) were studied. Age-matched children with hypertrophy of the adenoids and Eustachian tube dysfunction served as the control group. The number of past acute otitis media (AOM) episodes, their age, and the type of effusion were recorded for all children. Pro-inflammatory cytokine concentrations (TNF-α, IL-1β, IL-6 and IL-8) were determined and the presence of pathogenic bacteria in the patients' effusions was examined. High concentrations of TNF-α, IL-1β, IL-6 and IL-8 were found in the effusions in all children with chronic OME, with the highest levels observed in the non-atopic group. The atopic group showed persistently high IL-1β levels, while in the non-atopic children, IL-1β and TNF-α levels positively correlated with the patient's age and the number of past AOM episodes. Pathogenic bacteria were more frequently isolated from effusions in non-atopic children. In both atopic and non-atopic children, pro-inflammatory cytokines are found at high concentrations. This argues in favor of instituting anti-inflammatory management for treating OME, regardless of atopy.

2014-01-01

Full Text Available We describe the case of a 44-year-old woman with primary Burkitt lymphoma of the heart who presented with abdominal bloating and epigastric discomfort secondary to tamponade physiology caused by a large pericardial effusion. The pericardial fluid contained a large number of highly atypical lymphocytes with moderate basophilic cytoplasm, rare punched-out vacuoles, a vesicular nuclear chromatin, large nucleolus, and marginated chromatin that by FISH were positive for the 8;14 translocation. She had no other sites of disease. She was treated with four alternating cycles of modified CODOX-M and IVAC in combination with rituximab and remains in remission more than 5 years since diagnosis.

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

Objective: To determine the ability of 18 F-fluorodeoxyglucose (FDG) dual-head tomography with coincidence (DHTC) imaging in detecting lung cancer in patients with suspected malignant pleural effusion or malignant atelectasis on CT scanning and to differentiate benign and malignant pleural effusions in patients with lung cancer. Methods: One hundred and ten patients with suspected malignant pleural effusion (n=84) or atelectasis (n=26) but without primary lesions in the lungs on CT scanning underwent 18 F-FDG DHTC. Results: Thirty-eight of 110 patients were proven with lung cancer. Among the 38 lung cancer patients, 30 of them had pleural effusion and 8 of them had atelectasis. Seventy-two of 110 patients were proven with benign lung diseases. The sensitivity, specificity and accuracy of 18 F-FDG DHTC for detecting lung cancer in patients with suspected malignant pleural effusion or atelectasis were 97%, 78% and 85%, respectively. In 30 patients with lung cancer plus pleural effusion, 18 F-FDG DHTC correctly detected the presence of malignant pleural effusion and malignant pleural metastatic involvement in 18 of 21 patients and excluded malignant pleural effusion or pleural metastatic involvement in 8 of 9 patients (sensitivity, specificity and accuracy of 86%, 8/9 and 87%, respectively). Conclusion: 18 F-FDG DHTC imaging is a highly accurate and reliable noninvasive test for detecting primary malignant lesions in lung in patients with pleural effusion or atelectasis findings on CT scanning and is useful to differentiate malignant from benign pleural effusion in patients with lung cancer.

Isolated orbital mass as the primary presentation of a triple-hit lymphoma transformed from a systemic follicular lymphoma

Directory of Open Access Journals (Sweden)

Xiao Yi Zhou

2018-06-01

Full Text Available Purpose: Triple-hit lymphoma is a highly aggressive B-cell lymphoma. We report a case of triple-hit lymphoma transformed from systemic follicular lymphoma (FL after 9-year remission and presented primarily as an isolated orbital mass without systemic symptoms or lymphadenopathy. Observations: A 58-year-old female presented with intermittent vertical binocular diplopia, left upper eyelid swelling and pain and was found to have a 2.9 cm orbital mass. Histological section revealed a CD10-positive large B-cell lymphoma, consistent with transformation of FL. Fluorescent in situ hybridization (FISH analysis demonstrated rearrangements involving C-MYC, BCL-2 and BCL-6 genes, indicating a high grade, triple-hit lymphoma. Conclusions and importance: Triple-hit lymphoma transformed from a low-grade lymphoma may initially present as an isolated orbital mass without systemic evidence of transformation. Early recognition of double or triple-hit lymphomas is important since these patients require aggressive chemotherapy. Keywords: Lymphoma, Triple-hit lymphoma, Orbital mass

Physiology of breathlessness associated with pleural effusions

Thomas, Rajesh; Jenkins, Susan; Eastwood, Peter R.; Lee, Y.C. Gary; Singh, Bhajan

2015-01-01

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

2017-07-01

Chylous pericardial effusion is a rarely reported complication of lung cancer surgery. Here, we report a case of an elderly man who suffered chylous pericardial effusion after radical right upper lung resection for cancer. The massive chylous effusion first occurred in the pericardium, drained to the right chest after the drainage of the hydropericardium and subsequently moved back to the pericardium again. Lymphoscintigraphy examination indicated that a chylous fistula was present in the plane of the tracheal carina. After failure to control the chylous effusion with conservative medical treatment, the patient underwent video-assisted thoracic surgery through the left chest for thoracic duct ligation and pericardial fenestration. The patient was ultimately discharged without recurrence of the effusion after surgical treatment. This case report discusses the possible mechanism of chylopericardium after lung cancer surgery and suggests some strategies to prevent postoperative chylous pericardial effusion. © The Author 2017.

1993-01-01

The purpose of this study was to assess the efficacy of MR imaging in predicting the quality of ascites and pleural effusion. MR examinations of 20 patients with different benign or malignant diseases accompanied with ascites or pleural effusion were retrospectively studied. Results were compared with histopathological findings. On T 1 - and T 2 -weighted images, the MR intensity of the effusion depended mainly on the concentration of protein, whereas on gradient echo images, it depended mainly on the concentration of blood. MR examination was useful in non-invasively differentiating exudative or hemorrhagic effusion from serous effusion. Knowledge or inference of the quality of effusion can direct MR interpretation and may improve diagnostic accuracy. (author)

1980-01-01

We investigated 161 children under 24 months of age by CT of the skull and reviewed the anamnestic and clinical history. 87 children showed subdural effusions, and 74 did not. There were 33 patients with other pathological findings in CT, and 41 had normal scans. Age and sex distribution as well as localization of the subdural effusions were consistent with the literature. The 87 children with subdural effusions represented 1,7% in a sample of about 5.000 CT scans. CT was the most reliable method for diagnosis of subdural effusions, compared to other techniques. There was a preponderance of small subdural effusions from 1 to 7 mm thickness (51%). Other CT abnormalities accompanying subdural effusions were found. Most frequently the interhemispheric sulcus was dilated and an internal hydrocephalus was present. Also in our group there were 7 anamnestical and 6 clinical symptoms highly diagnostic of subdural effusions. (orig.) [de

Radiotherapy of adult nodal non Hodgkin's lymphoma

Gamen, G.; Thirion, P.

1999-01-01

The role of radiotherapy in the treatment of nodal non-Hodgkin's lymphoma has been modified by the introduction of efficient chemotherapy and the development of different pathological classifications. The recommended treatment of early-stage aggressive lymphomas is primarily a combination chemotherapy. The interest of adjuvant radiotherapy remains unclear and has to be established through large prospective trials. If radiation therapy has to be delivered, the historical results of exclusive radiation therapy showed that involved-fields and a dose of 35-40 Gy (daily fraction of 1.8 Gy, 5 days a week) are the optimal schedule. The interest of radiotherapy in the treatment of advanced-stage aggressive lymphoma is yet to be proven. Further studies had to stratify localized stages according to the factors of the International Prognostic Index. For easy-stage low-grade lymphoma, radiotherapy remains the standard treatment. However, the appropriate technique to use is controversial. Involved-field irradiation at a dose of 35 Gy seems to be the optimal schedule, providing a 10 year disease-free survival rate of 50 % and no major toxicity. There is no standard indication of radiotherapy in the treatment advanced-stage low-grade lymphoma. For 'new' nodal lymphoma's types, the indication of radiotherapy cannot be established (mantle-zone lymphoma, marginal zone B-cell lymphoma) or must take into account the natural history (Burkitt's lymphoma, peripheral T-cell lymphoma) and the sensibility to others therapeutic methods.

Triple-hit lymphoma is a highly aggressive B-cell lymphoma. We report a case of triple-hit lymphoma transformed from systemic follicular lymphoma (FL) after 9-year remission and presented primarily as an isolated orbital mass without systemic symptoms or lymphadenopathy. A 58-year-old female presented with intermittent vertical binocular diplopia, left upper eyelid swelling and pain and was found to have a 2.9 cm orbital mass. Histological section revealed a CD10-positive large B-cell lymphoma, consistent with transformation of FL. Fluorescent in situ hybridization (FISH) analysis demonstrated rearrangements involving C-MYC, BCL-2 and BCL-6 genes, indicating a high grade, triple-hit lymphoma. Triple-hit lymphoma transformed from a low-grade lymphoma may initially present as an isolated orbital mass without systemic evidence of transformation. Early recognition of double or triple-hit lymphomas is important since these patients require aggressive chemotherapy.

1985-01-01

A 25-year-old female was admitted with shortness of breath and abdominal swelling. Six years before the admission, she had received resection of 7th to 9th left ribs and subsequent radiation of 5,000 rads to the thorax for the treatment of rib osteoblastoma. One year after the radiation, marked pericardial effusion associated with acute pericarditis was observed and was improved by digitalization and diuretic therapy. Since two years after the radiation, she had felt easy fatigability, swelling of face and foot, and transient faintness on more than 10 meters running. On admission, chest X-ray photograph showed increased pulmonary vascularity without cardiac enlargement. Electrocardiogram indicated systolic right ventricular strain, mitral P, and nonspecific S-T segment depression in left precordial leads. Two-dimensional echocardiography presented pericardial effusion with posterior pericardial thickening, while M-mode echocardiography showed diastolic posterior movement of interventricular septum and diastolic flattening of left ventricular posterior wall. Cardiac catheterization revealed marked elevation of mean right atrial pressure, pulmonary arterial diastolic pressure, right and left ventricular end-diastolic pressure, accompanied with their equalization. In addition, pressure waves of right and left ventricle showed diastolic dip and plateau. Phono-cardiogram and apexcardiogram presented pericardial knock sound and systolic retraction, respectively. Cardiac angiography showed diastolic restriction of left ventricle without any stenosis of coronary artery. Computed tomography (CT) of the chest revealed thickening of anterior and left lateral pericardium with expansion of inferior vena cava, and abdominal CT revealed ascites with slight enlargements of liver and spleen. From above obtained data, chronic effusive-constrictive pericarditis, which was attributed to radiation, was strongly suggested. (J.P.N.)

Full Text Available Breast involvement by lymphoma is uncommon and poses challenges in diagnosis. Breast involvement by malignant lymphoma, whether primary or secondary, is a rare event. Primary breast lymphomas account for 0.38% - 0.7% of all non-Hodgkin lymphomas, 1.7%-2.2% of all extranodal non-Hodgkin lymphomas, and only 0.04% - 0.5% of all breast cancer cases. Most frequent primary breast lymphomas are diffuse large B cell lymphomas (53%. Breast mucosa-associated lymphoid tissue (MALT lymphomas account for a small fraction of all the MALT lymphomas (1% - 2%. Herein we report a case of a patient with primary breast MALT lymphoma and its presentation on different imaging modalities. Two years after the presentation and treatment with eight cycles of chemotherapy, the patient is alive and well, without evidence of residual disease or recurrence.

Recurrent hemorrhagic pericardial effusion in a child due to diffuse lymphangiohemangiomatosis: a case report

2010-02-01

Full Text Available Abstract Introduction Recurrent hemorrhagic pericardial effusion in children with no identifiable cause is a rare presentation. Case presentation We report the case of a 4-year-old Indian girl who presented with recurrent hemorrhagic pericardial effusion. Diffuse lymphangiomatosis was suspected when associated pulmonary involvement, soft tissue mediastinal mass, and lytic bone lesions were found. Pericardiectomy and lung biopsy confirmed the diagnosis of diffuse lymphangiohemangiomatosis. Partial clinical improvement occurred with thalidomide and low-dose radiotherapy, but our patient died from progressive respiratory failure. Conclusion Diffuse lymphangiohemangiomatosis should be considered in the differential diagnosis of hemorrhagic pericardial effusion of unclear cause.

Central nervous system (CNS) involvement in systemic B-cell non-Hodgkin lymphoma (B-NHL) at diagnosis (sysCNS) is rare. We investigated the outcome of 21 patients with sysCNS, most commonly diffuse large B-cell lymphoma, treated with high dose methotrexate (HD-MTX) and R-CHOP. The median number of cycles of HD-MTX and R-CHOP was 4 (range 1-8) and 6 (range 0-8), respectively. Consolidative whole brain radiotherapy (WBRT) was given to 33% (7/21) patients. With a median follow-up of 44 months the 3-year progression free survival (PFS) and overall survival (OS) were 45% (95%CI 34-56%) and 49% (95%CI 38-60%), respectively. Over 90% of patients had an unfavorable international prognostic index score, reflected by treatment-related mortality of 19% (4/21) and relapse-related mortality of 28% (6/21). The outcome of these patients was, however, unexpectedly good when compared to secondary CNS relapses. Prospective studies are needed to define the optimal treatment for patients with sysCNS, but its rarity might be challenging.

Objective: To review the approach to the diagnosis, assessment, treatment and continuing management of patients with Non-Hodgkin's lymphoma with the emphasis on the role of radiation therapy in this group of diseases. The entity of 'Non-Hodgkin's Lymphoma' encompasses a diverse group of disorders involving almost any part of the body. This diversity bedevils any attempt to unify the approach to this disease on a rational basis. Nevertheless, some broad principles can be applied to almost any presentation of Non-Hodgkin's lymphoma. The approach to the management of Non-Hodgkin's lymphoma is based on the histologic type, localization and extent of disease and other disease and patient related prognostic factors. The accurate pathologic diagnosis of lymphoma has been greatly facilitated by availability of markers, molecular and genetic techniques. The newly proposed revised classification of lymphomas and its impact on these of RT will be discussed. Although the Ann Arbor staging classification has been shown to provide important prognostic information, other factors have equivalent, if not greater, influence on outcome in patients with Non-Hodgkin's lymphomas. The management of lymphomas is based primarily on the histologic type and extent of the disease including stage, tumour bulk, number of sites involved and location of the disease. The success of curative radiation therapy is contingent upon the presence of localized disease, normal tissue tolerance allowing the delivery of RT curative dose (30-35 Gy) and the tumour bulk. The current evidence suggests that locoregional RT for stage I and II low grade lymphoma results in approximately 50% prolonged (10-15 years) failure free rate and possible cure. Radiation alone is no longer used for intermediate and high grade lymphomas. The standard management of stage I and II intermediate grade large cell and mixed lymphomas is with doxorubicin based chemotherapy (e.g. CHOP) followed by involved field radiation. The

Pericardial effusion is a common finding in everyday clinical practice. The first challenge to the clinician is to try to establish an etiologic diagnosis. Sometimes, the pericardial effusion can be easily related to a known underlying disease, such as acute myocardial infarction, cardiac surgery, end-stage renal disease or widespread metastatic neoplasm. When no obvious cause is apparent, some clinical findings can be useful to establish a diagnosis of probability. The presence of acute inflammatory signs (chest pain, fever, pericardial friction rub) is predictive for acute idiopathic pericarditis irrespective of the size of the effusion or the presence or absence of tamponade. Severe effusion with absence of inflammatory signs and absence of tamponade is predictive for chronic idiopathic pericardial effusion, and tamponade without inflammatory signs for neoplastic pericardial effusion. Epidemiologic considerations are very important, as in developed countries acute idiopathic pericarditis and idiopathic pericardial effusion are the most common etiologies, but in some underdeveloped geographic areas tuberculous pericarditis is the leading cause of pericardial effusion. The second point is the evaluation of the hemodynamic compromise caused by pericardial fluid. Cardiac tamponade is not an “all or none” phenomenon, but a syndrome with a continuum of severity ranging from an asymptomatic elevation of intrapericardial pressure detectable only through hemodynamic methods to a clinical tamponade recognized by the presence of dyspnea, tachycardia, jugular venous distension, pulsus paradoxus and in the more severe cases arterial hypotension and shock. In the middle, echocardiographic tamponade is recognized by the presence of cardiac chamber collapses and characteristic alterations in respiratory variations of mitral and tricuspid flow. Medical treatment of pericardial effusion is mainly dictated by the presence of inflammatory signs and by the underlying disease if

The diagnosis of hypothyroidism is difficult because hypothyroidism in adults and especially the elderly, classic, has an insidious onset with a range of nonspecific symptoms which may delay diagnosis for months or even years. Old age seems to represent trigger factor for autoimmune diseases, including hypothyroidism. Clinical features in hypothyroidism, such as weight gain, fatigue, cold intolerance, constipation, dry skin, edema and muscle weakness, and decreased osteo-tendinous reflexes are usually subtle and can be overlooked. Thyroid dysfunction may be associated with a negative impact on the cardiovascular system. Pericardial, pleural and peritoneal effusions are common findings in hypothyroidism. This case report represents a typical primary hypothyroidism (autoimmune) and shows the clinical features of this disease. Basically we talked about a severe myxedema with the involvement of internal organs in an elderly woman and the euthyroidism restoration, under thyroid replacement therapy, was correlated with the clinical improvement and cardiovascular and neurological status, with radiographic remission and regression to extinction of pericardial effusion at repeated echocardiographic evaluations.

Objective: To analyze the frequencies of histological types of lymphoma, diagnosed with complete immunohistochemical profile in younger and older age group. Study Design: Cross-sectional analytical study. Place and Duration of Study: Dow Diagnostic Research and Reference Laboratory, Dow University of Health Sciences, Karachi, from January 2009 to September 2013. Methodology: Consecutive cases of lymphomas, which were diagnosed using immunohistochemistry, were analyzed according to WHO classification. Frequency and percentages for different types of lymphomas were calculated. Hodgkin and non-Hodgkin lymphomas characteristics in two age groups of less than and more than 40 years were compared, applying chi-square test. Results: Out of the 318 cases, 79 (25 percentage) were Hodgkin Lymphomas (HL) and 239 (75 percentage) were Non-Hodgkin Lymphomas (NHL). Mixed Cellularity Hodgkin Lymphoma (MCHL) was the commonest (n=48). Amongst the NHL, 215 (89.95 percentage) were B cell lymphomas and 24 (10.05percentage) were T-cell lymphomas. Diffuse Large B-Cell Lymphoma (DLBCL) was the commonest lymphoma (n=165, 69.95 percentage of NHL). Anaplastic T-Cell Lymphoma (ALCL, n=10) was the commonest T-cell lymphoma. The frequency of HL was significantly higher in the younger age group and that of NHL was higher in the older age group (p < 0.001). Primary lymph node involvement was reported in 175 (55 percentage) and cervical lymph node was the most frequent site. Extra nodal involvement was seen in 93 (29 percentage) of all cases and was reported in 87 (36.4 percentage) of NHL and 6 (7.5 percentage) of HL. The most common extra nodal site was the gastrointestinal tract. Conclusion: Hodgkin lymphoma comprises 25 percentage and non-Hodgkin lymphoma comprises 75 percentage of all lymphomas. Both occur in younger age groups than reported in the West. B-cell NHL is three times more common than T-cell lymphoma. DLBCL is the most frequent lymphoma. ALCL is the most common T-cell, and mixed

The interrelationship between the etiology of pleural effusion and the side of its occurrence has been a subject of clinical interest for many years. It has often been stated that pleural effusion caused by congestive heart failure tends to occur on the right side. However, some authors contended that such a side proclivity is not reliable. In the present study, the authors investigated the laterally of effusion caused by various cardiovascular diseases complicated by heart failure. We reviewed the chest X-ray films and clinical records of 68 patients with proven pleural effusion resulted from heart failure. 1. There were 34 men and 34 women with the age ranging from 10 to 84 years with the mean of 59. 2. The diagnoses were rheumatic heart disease (2 patients), coronary heart disease (10 patients), hypertensive heart disease (8 patients), mitral valvular disease (18 patients), aortic valvular disease (3 patients), and miscellaneous (27 patients). 3. 34 patients had unilateral pleural effusion, 25 and 9, right and left, respectively. Of the 34 patients with bilateral effusion, 13 patients had predominantly right-sided effusion, 5 patients had predominantly left-sided effusion and 16 patients had evenly distributed bilateral effusion. Thus, 55.8% of effusion was right-sided

The level s of four tumor markers (AM, CYFRA21-1, NSE and CEA) pleural effusion in plearal effusion were determined by RIA in 52 patients with tuberculous pleural effusion and 74 patients with malignant pleural effusion. The results showed that the levels of the four tumor markers in malignant pleural effusion were significantly higher than those in tuberculous pleural effusion. Combined detection of the four tumor markers could improve the diagnostic sensitivity and the accuracy to 90.5% and 92.9%, respectively (P<0.01). Detection of AM, CYFRA21-1, NSE and CEA levels in pleural effusion is very useful for the differentiation of malignant from tuberculous pleural effusion. Combined detection of the four markers may greatly improve the diagnostic accuracy. (authors)

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

Background and purpose: To describe new concepts for radiation fields in patients with early stage Hodgkin lymphoma treated with a combined modality. Patients and materials: Patients receiving combined modality therapy with at least 2 or 3 cycles of chemotherapy prior to radiotherapy. Pre- and postchemotherapy cervical and thoracic CT scans are mandatory and should be performed, whenever possible, in the treatment position with the use of image fusion capabilities. A pre-chemotherapy PET scan is strongly recommended to increase the detection of involved lymph nodes. Results: Radiation fields are designed to irradiate the initially involved lymph nodes exclusively and to encompass their initial volume. In some cases, radiation fields are slightly modified to avoid unnecessary irradiation of muscles or organs at risk. Conclusions: The concept of involved-node radiotherapy (INRT) described here is the first attempt to reduce the size of radiation fields compared to the classic involved fields used in adult patients. Proper implementation of INRT requires adequate training and an efficient prospective or early retrospective quality assurance program

We are reporting the case of a 58-year-old woman with history of bilateral silicone breast implants for cosmetic augmentation. At 2-year interval from receiving the breast implants, she presented with swelling of the right breast with associated chest wall mass, effusion around the implant, and axillary lymphadenopathy. Pathology confirmed breast implant-associated anaplastic large cell lymphoma (stage III, T4N2M0, using BIA-ALCL TNM staging and stage IIAE, using Ann-Arbor staging). The patient underwent bilateral capsulectomy and right partial mastectomy with excision of the right breast mass and received adjuvant CHOP chemotherapy and radiation to the right breast and regional nodes. Since completion of multimodality therapy, the patient has sustained remission on both clinical exam and PET/CT scan. We report this case and review of the literature on this rare form of lymphoma.

The authors review the main findings of primary adrenal lymphoma on abdominal and brain computed tomography (CT) scans and brain magnetic resonance imaging (MRI), and report a rare case of a 72-year-old male patient with deterioration in mental status progressing from recent memory loss to disorientation and ultimately dementia in a period of two months. The patient was investigated using imaging methods including brain (without intravenous administration of iodinated contrast media), chest and abdomen (pre and post intravenous administration of iodinated contrast media) CT scans and brain MRI (pre and post intravenous administration of gadolinium). Brain CT scan showed slightly hyperdense nodules adjacent to the lateral ventricles. No gross abnormalities were seen on the chest CT scan. CT of the abdomen showed solid nodules on both adrenals. Brain MRI showed diffuse nodular enhancement of the ependyma of the fourth ventricle, third ventricle, frontal and temporal horns, atria and body of the lateral ventricles. Definitive diagnosis was made by immunohistochemical study of the biopsed adrenal. After a comprehensive review of the literature the authors concluded that CT and MRI are essential methods for the detection and accurate evaluation of primary adrenal lymphomas, particularly when there is involvement of the central nervous system. MRI is more sensitive in the detection of extracerebral lesions in the epidural and subdural spaces, especially after intravenous administration of gadolinium. (author)

A very complicated pleural effusion

Discussion: Re-expansion pulmonary oedema is a recognised complication of large pleural effusion drainage. The mechanism remains unclear, although reduced left ventricular function, in this case from a possible pericardial effusion, may be a precipitant. To prevent this phenomenon the British Thoracic Society recommends draining a maximum of 1.5 litres of fluid. This case was further complicated by a pneumothorax; again a recognised complication, especially if there is underlying poor compliance of the lung parenchyma. Re-expansion pulmonary oedema has an incidence of <1% and pneumothorax <5%. Their occurrence has not previously been reported simultaneously. Large pleural effusions are commonly encountered in clinical practice in South Africa. The existence of multiple co-morbidities including tuberculosis, HIV and impaired cardiac function may complicate their management. This case highlights the need for close monitoring and controlled drainage of pleural effusions in emergency practice.

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.

Full Text Available Postoperative pulmonary complications, following upper abdominal surgery, occur at a rate which is higher, than lower abdominal surgery. One of these complications is pleural effusion. In this study, the frequency and causes of pleural effusions and the changes of the blood gas values and pulmonary functions of the patients with pleural effusions, occured after upper abdominal surgery are discussed in the accompaniment of the literature. Material and Methods:148 patients to whom upper adominal surgery is performed and in 47 of these patients pleural effusion is developed (31.75% , were examined restrospectivitely. Preoperative and postoperative pulmonary function tests (PFT and arterial blood gas (ABG results and the blood proteins, albumin values were recorded. The anesthesia type, the surgery properties, involving type of surgery and the surgical incision were determined. Results:Pleural effusion is detected bilaterally in 8 patients (17:02, at the rightside in 21 patients (44.69% ,and at the left side in 18 patients (38.29%.The 40.42% (19 cases of the patients who has pleural effusion in the postoperative period, had liver and gallbladder surgery, the %23.41 (11 Cases had spleen and pancreas surgery and the %36.17 (17 cases had the  other surgical procedures.Conclusions: While the upper abdominal surgery, impairment of the integrity of the diaphragm‘s peritoneum that covers the abdominal cavity where there is a highliquid pressure, may cause the liquid transition to the pleural space that has a negative pressure. Hypoalbuminemia and hipoproteinemia, that will occur due to the changes of oral intake and diet regulation in the postoperative period, may cause a reason for the pleural effusion. For this reason, doctors who performed these surgery procedures, should not ignore this complication, in the period of postoperative follow-ups of the patients.

Presumed hydrochlorothiazide-associated immunologic-hypersensitivity-induced pericardial effusion

Full Text Available A 50-year-old Caucasian female presented for a second opinion regarding a newly diagnosed pericardial effusion. Seven months previously, hydrochlorothiazide was introduced into her pharmacologic regimen to aid in the management of her hypertension. A routine echocardiogram indicated a large pericardial effusion with signs of early cardiac tamponade. The patient subsequently underwent successful pericardiocentesis with complete drainage of the pericardial effusion. The effusion was empirically attributed to a viral etiology. Repeat echocardiograms showed recurrence of the pericardial effusion. Prior to undergoing a second pericardiocentesis with pericardial biopsy, as her physicians recommended, the patient sought a second opinion. While obtaining the patient’s history, an allergy to sulfa was elicited. The possibility that the pericardial effusion may be secondary to an immunologic-hypersensitivity reaction was considered. It was recommended the patient discontinue the use of hydrochlorothiazide. Nine days following discontinuation of hydrochlorothiazide and without any other intervention, an echocardiogram was reported to show the size of the pericardial effusion had subsided substantially. Nine weeks following discontinuation, almost complete resolution of the pericardial effusion was reported. It is hypothesized that when treated with hydrochlorothiazide, the patient had an immune response leading to the pericardial effusion.

Full Text Available An endemic outbreak of melioidosis developed in southern Taiwan following a flood caused by a typhoon in July 2005. A total of 27 patients were diagnosed with the acute and indigenous form of pulmonary melioidosis. Parapneumonic pleural effusions were noted on chest X-rays in six patients. Thoracentesis was done in three patients and all revealed lymphocyte predominance in differential cell count. Burkholderia pseudomallei was isolated in the pleural effusion in one of them. All three patients survived after antibiotic treatment. Lymphocytic pleural effusion is generally seen in tuberculosis or malignancy. However, our findings suggest that melioidosis should be considered in the differential diagnosis of lymphocytic pleural effusion.

Objective. To assess the radiological features of Morel-Lavallee effusion in the thigh. Design and patients. A restrospective study of clinical records and radiological studies was carried out on three patients with Morel-Lavallee effusion. Results and conclusions. Ultrasound and computed tomography (CT) were able to locate the effusion in the three patients. CT demonstrated a capsule around the lesion. A fluid-fluid level was visible with both techniques. Ultrasound and CT are good methods for assessing patients with Morel-Lavallee effusion of the thigh. CT can be used to distinguish patients requiring surgical treatment from those who could be treated by conservative measures. (orig.). With 4 figs

Background Of the 1.5 million people diagnosed with pleural effusion annually in the U.S., approximately 178,000 undergo thoracentesis. While it is known that malignant pleural effusion portends a poor prognosis, mortality of patients with nonmalignant effusions has not been well studied. Methods This prospective cohort study evaluated 308 patients undergoing thoracentesis. Chart review was performed to obtain baseline characteristics. The etiology of the effusions was determined using standardized criteria. Mortality was determined at 30-days and 1-year. Results 247 unilateral and 61 bilateral thoracenteses were performed. Malignant effusion had the highest 30-day (37%) and 1 year (77%) mortality. There was substantial patient 30-day and 1-year mortality with effusions due to multiple benign etiologies (29% and 55%), CHF (22% and 53%), and renal failure (14% and 57%). Patients with bilateral pleural effusion, relative to unilateral, were associated with higher risk of death at 30 days and 1 year (17% versus 47%; HR 2.58 CI [1.44–4.63] and 36% versus 69%; HR 2.32 CI [1.55–3.48]). Conclusions Patients undergoing thoracentesis for pleural effusion have high short and long-term mortality. Patients with malignant effusion had the highest mortality followed by multiple benign etiologies, CHF and renal failure. Bilateral pleural effusion is distinctly associated with high mortality.

Proclus and Mulla Sadra on First Effusion

Directory of Open Access Journals (Sweden)

Saeed Rahimiyan

2014-01-01

Full Text Available Mulla Sadra Mulla Sadra's philosophical system is built upon the belief in unique origin of world to which all diversities can be reduced. Then First Effusion debate can be taken on in this system. According to the principle which reads "from the One nothing is effused but One", contingent beings could not have been emanated from the Necessary Being in a horizontal fashion due to their diversity. Rather they have been effused from the Necessary in a vertical fashion and through a hierarchy of causes and effects. The first stage of the hierarchy is being represented by the First Effusion. Pre-Sadraeian theosophers regarded the First Effusion the first intellect in vertical chain of intellects. Mulla Sadra have two theories of the First Effusion. In some of his books he introduces the first intellect as the first entity effused from the Necessary keeping his pace with his own predecessors. But in some other works like Asfar he describes the Ever-unfolding existence as the First Effusion and takes it to be his final position. Having replaced existential gradation with causation and also individual unity of existence with existential gradation, Mulla Sadra asserts that the First Effusion could only be the Ever-unfolding Existence which is a manifestation of Divine Essence not an independent existence. It is indeed nothing but the Divine Essence although in the form of its first manifestation. Thus the Ever-unfolding Existence has three distinguished attributes which make it qualified to stand in direct relationship with Divine Essence, Existential (and not conceptual universality and comprehensiveness which enables this existence to include the other manifestions. Lack of particular limitation and determination; this is why it can reveal itself to every being in its own peculiar existential terms.

The adenoid pad has been considered a reservoir for bacteria in the pathogenesis of otitis media with effusion. This study aimed to characterize the middle ear microbiota in children with otitis media with effusion and establish whether a correlation exists between the middle ear and adenoid microbiota. Prospective, controlled study. Middle ear aspirates adenoid pad swabs were collected from 23 children undergoing ventilation tube insertion. Adenoid swabs from patients without ear disease were controls. Samples were analyzed using 16S rRNA sequencing on the Illumina MiSeq platform. Thirty-five middle ear samples were collected. The middle ear effusion microbiota was dominated by Alloiococcus otitidis (23% mean relative abundance), Haemophilus (22%), Moraxella (5%), and Streptococcus (5%). Alloiococcus shared an inverse correlation with Haemophilus (P = .049) and was found in greater relative abundance in unilateral effusion (P = .004). The microbiota of bilateral effusions from the same patient were similar (P effusion microbiota were found to be dissimilar to that of the adenoid (P = .01), whereas the adenoid microbiota of otitis media with effusion and control patients were similar (P > .05) (permutational multivariate analysis of the variance). Dissimilarities between the local microbiota of the adenoid and the middle ear question the theory that the adenoid pad is a significant reservoir to the middle ear in children with otitis media with effusion. A otitidis had the greatest cumulative relative abundance, particularly in unilateral effusions, and shares an inverse correlation with the relative abundance of Haemophilus.

2011-01-01

Background Several symptom-relieving interventions have been shown to be efficacious among osteoarthritis (OA) patients with knee effusion; however, not every symptomatic knee OA patient has clinical effusion. Results may be over-generalized since it is unclear if effused knees represent a unique pathological condition or subset compared to knees without effusion. The primary purpose of this study was to determine if biochemical differences existed between OA knees with and without effusion. Methods The present cross-sectional study consisted of 22 volunteers (11 with knee effusion, 11 without knee effusion) with confirmed late-stage radiographic knee OA (Kellgren-Lawrence score ≥ 3). Synovial fluid samples were collected and analyzed using a custom multiplex enzyme-linked immunosorbent assay to determine eight specific biomarker concentrations (e.g., catabolic, anabolic). Results Matrix metalloproteinase (MMP)-3, tissue inhibitor of MMPs (TIMP)-1, TIMP-2, and interleukin-10 were significantly higher in the knees with effusion than in the knees without effusion. Conclusions The biochemical differences that existed between knees with and without effusion provide support that OA subsets may exist, characterized by distinct biochemical characteristics and clinical findings (e.g., effusion).

Growth arrest lines appear as dense sclerotic lines parallel to the growth plate of long bones on radiography. We describe the case of a 9-year-old female with growth arrest lines initially masquerading as lymphoma involvement on 99m Tc-MDP bone scintigraphy who had been treated with chemotherapy for non-Hodgkin's lymphoma about 3 years previously. Subsequent regional bone SPECT/CT clearly diagnosed the growth arrest lines, and retrograde review of previous bone scintigraphy demonstrated line migration in this patient. Growth arrest lines should be considered a possible diagnosis on bone scintigraphy, especially in the surveillance of children who have experienced severe childhood infections, malnutrition, immobilization, or treatment with immunosuppressive or chemotherapeutic drugs that may inhibit bone growth

STUDY DESIGN Descriptive prospective cohort study. OBJECTIVES To investigate the relationships between knee joint effusion, quadriceps activation, and quadriceps strength. These relationships may help clinicians better identify impaired quadriceps activation. BACKGROUND After anterior cruciate ligament (ACL) injury, the involved quadriceps may demonstrate weakness. Experimental data have shown that quadriceps activation and strength may be directly mediated by intracapsular joint pressure created by saline injection. An inverse relationship between quadriceps activation and the amount of saline injected has been reported. This association has not been demonstrated for traumatic effusion. We hypothesized that traumatic joint effusion due to ACL rupture and postinjury quadriceps strength would correlate well with quadriceps activation, allowing clinicians to use effusion and strength measurement as a surrogate for electrophysiological assessment of quadriceps activation. METHODS Prospective data were collected on 188 patients within 100 days of ACL injury (average, 27 days) referred from a single surgeon. A complete clinical evaluation of the knee was performed, including ligamentous assessment and assessment of range of motion and effusion. Quadriceps function was electrophysiologically assessed using maximal volitional isometric contraction and burst superimposition techniques to quantify both strength and activation. RESULTS Effusion grade did not correlate with quadriceps central activation ratio (CAR) (zero effusion: mean ± SD CAR, 93.5% ± 5.8%; trace effusion: CAR, 93.8% ± 9.5%; 1+ effusion: CAR, 94.0% ± 7.5%; 2+/3+ effusion: CAR, 90.6% ± 11.1%). These values are lower than normative data from healthy subjects (CAR, 98% ± 3%). CONCLUSION Joint effusion after ACL injury does not directly mediate quadriceps activation failure seen after injury. Therefore, it should not be used as a clinical substitute for electrophysiological assessment of quadriceps

Pericardial Effusion and Pericardiocentesis: Role of Echocardiography

Science.gov (United States)

2012-01-01

Pericardial effusion can develop from any pericardial disease, including pericarditis and several systemic disorders, such as malignancies, pulmonary tuberculosis, chronic renal failure, thyroid diseases, and autoimmune diseases. The causes of large pericardial effusion requiring invasive pericardiocentesis may vary according to the time, country, and hospital. Transthoracic echocardiography is the most important tool for diagnosis, grading, the pericardiocentesis procedure, and follow up of pericardial effusion. Cardiac tamponade is a kind of cardiogenic shock and medical emergency. Clinicians should understand the tamponade physiology, especially because it can develop without large pericardial effusion. In addition, clinicians should correlate the echocardiographic findings of tamponade, such as right ventricular collapse, right atrial collapse, and respiratory variation of mitral and tricuspid flow, with clinical signs of clinical tamponade, such as hypotension or pulsus paradoxus. Percutaneous pericardiocentesis has been the most useful procedure in many cases of large pericardial effusion, cardiac tamponade, or pericardial effusion of unknown etiology. The procedure should be performed with the guidance of echocardiography. PMID:23236323

Full Text Available The detection of breast carcinoma cells in effusions is associated with rapidly fatal outcome, but these cells are poorly characterized at the molecular level. This study compared the gene array signatures of breast carcinoma cells in primary carcinomas and effusions. The genetic signature of 10 primary tumors and 10 effusions was analyzed using the Array-Ready Oligo set for the Human Genome platform. Results for selected genes were validated using PCR, Western blotting, and immunohistochemistry. Array analysis identified 255 significantly downregulated and 96 upregulated genes in the effusion samples. The majority of differentially expressed genes were part of pathways involved in focal adhesion, extracellular matrix-cell interaction, and the regulation of the actin cytoskeleton. Genes that were upregulated in effusions included KRT8, BCAR1, CLDN4, VIL2, while DCN, CLDN19, ITGA7, and ITGA5 were downregulated at this anatomic site. PCR, Western blotting, and immunohistochemistry confirmed the array findings for BCAR1, CLDN4, VIL2, and DCN. Our data show that breast carcinoma cells in primary carcinomas and effusions have different gene expression signatures, and differentially express a large number of molecules related to adhesion, motility, and metastasis. These differences may have a critical role in designing therapy and in prognostication for patients with metastatic disease localized to the serosal cavities.

Microfilaria in pleural effusion: An unusual association

Full Text Available Lymphatic filariasis is a major public health problem in tropical countries and India is endemic for it. However, lymphatic filariasis presenting as pleural effusion is an unusual manifestation and finding microfilaria in pleural effusion without any lung pathology is rare. We report a case of pleural effusion without any underlying lung pathology and normal blood picture. Clinical cure occurred after treatment with diethyl-carbamazepine. Filariasis should be kept in view while considering the differential diagnosis of idiopathic pleural effusion, especially in endemic countries.

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.

Objective: To study the CT manifestations of abdominal and pelvic lymph nodes in non- Hodgkin lymphoma (NHL) of Chinese patients, and to investigate their correlation with pathology subtypes. Methods: The CT images of 241 patients with enlargement of abdominal and pelvic lymph nodes involved by NHL were reviewed. Of them, 96 patients whose clinical and imaging data fulfilled the requirement for analysis were included. According to the Clinical Schema for the Lymphoid System, patients were divided into 3 subtypes, indolent lymphoma (IL; n=31), aggressive lymphoma (AL; n=61), very aggressive lymphoma (VAL; n=2), and unclassified lymphoma (UCL; n=2), respectively. Abdominal and pelvic CT scans were undertaken in 46 patients, abdominal CT only in 47 cases, and pelvic CT only in 3 cases. CT with iv contrast administration was obtained in 80 patients. Anatomic sites involved were nominated as retroperitoneal (i.e. paraaortic), abdominal (including paracardiac, gastrohepatic, hepatic hilar, and mesenteric etc), retrocrural, diaphragmatic, common iliac, internal iliac, external iliac, and inguinal nodes, respectively. Size, number, discreteness, and density of the nodal lesions were analyzed, and correlated with pathology subtypes. The minimal dimension of the largest node was measured. Results: (1) Size: Most of the nodes were ≤2 cm in size, 60.5% (219/362 sites) in IL and AL, 56.6% (77/136 sites) in IL, and 62.8%(142/226 sites) in AL, respectively. There was no statistical significant difference of the nodal size between IL and AL in each location (χ 2 =0.341, P=0.559). (2) Number: Mesentery had the largest number of node involvement (6.5 vs 5 nodes on an median, IL vs AL), with retroperitoneum placed second (4 vs 4 nodes, IL vs AL. (3) Discreteness: Most of the nodes were discrete with an incidence of 77.1% (279/362 sites, IL and AL), and 74.3% (101/136 sites) in IL, 78.8% (178/226 sites) in AL, respectively. No statistical significant discrepancy was found between

Computed tomography studies are usually used to assess patients with pleural effusions, and radiologists should be aware of the significance of different CT findings for the diagnosis of the effusion. The purpose of this study was to evaluate CT findings for etiological diagnosis of pleural effusions. Contrast-enhanced CT of the chest of 211 patients with pleural effusion of definite diagnosis were evaluated. The CT images were evaluated for the presence and extent of pleural effusion, thickening or nodules, extrapleural fat and other changes in the mediastinum or lung. The CT scans were read by two independent observers and correlation between them was evaluated. Comparison of CT findings between benign and malignant effusions, between exudates and transudates, and between empyemas and the other parapneumonic effusions were carried out. Kappa values for most CT findings were >0.85. Loculation, pleural thickening, pleural nodules, and extrapleural fat of increased density were only present in exudative effusions. Multiple pleural nodules and nodular pleural thickening were the only pleural findings limited to malignant pleural effusions. The signs were also more frequently seen in empyemas than in other parapneumonic effusions. Computed tomography findings can help to distinguish between transudates and exudates. Although there is some overlap between benign and malignant pleural effusions, pleural nodules and nodular pleural thickening were present almost exclusively in the latter. Although differences between CT findings of empyemas and the other parapneumonic effusions exist, there is no finding which can definitely differentiate between them. (orig.)

In order to prevent central nervous system (CNS) involvement and improve the prognosis of primary intraocular lymphoma (PIOL), we prospectively evaluated the efficacy of combined therapy using intravitreal methotrexate (MTX) and systemic high-dose MTX on treatment-naïve PIOL. Patients with newly diagnosed PIOL whose lymphoma was limited to the eyes were enrolled. The patients were treated with weekly intravitreal MTX until the ocular lesions were resolved, followed by five cycles of systemic high-dose MTX (3.5 g/m 2 ) every other week. Ten patients were enrolled in this study and completed the treatment. All patients achieved complete response for their ocular lesions with rapid decrease of intravitreal interleukin-10 concentration. Adverse events of intravitreal and systemic high-dose MTX were mild and tolerable. With a median follow-up of 29.5 months, four patients (40%) experienced the CNS disease development and the mean CNS lymphoma-free survival (CLFS) time was 51.1 months. Two-year CLFS, which was the primary end-point of the study, was 58.3% (95% confidence interval, 23.0-82.1%). In contrast, eight patients were treated with intravitreal MTX alone in our institute, and their 2-year CLFS was 37.5% (95% confidence interval, 8.7-67.4%). In conclusion, systemic high-dose MTX following intravitreal MTX is feasible and might be effective in preventing CNS involvement of PIOL. Further arrangements are worth considering in order to improve the effects. This study was registered with UMIN Clinical Trials Registry (UMIN000003921). © 2016 The Authors.

Plasmablastic lymphoma (PBL) is a rare and aggressive subtype of non-Hodgkin lymphoma that commonly occurs in human immunodeficiency virus (HIV)-positive individuals, and affects oral sites. Occasionally, it has been described in HIV-negative patients and involving non-oral sites. Pathologically, PBL is a high-grade B-cell lymphoma that displays the immunophenotype of a terminally differentiated B-lymphocyte with loss of B-cell markers (CD20) and expression of plasma-cell antigens. Epstein-Barr virus infection and MYC rearrangements are frequently observed. Treatment of PBL is challenging because of the lack of established treatment and poor outcomes, with median survival times shorter than one year. In this review, we discuss the clinical and epidemiologic spectrum of PBL as well as its distinct pathological features. Finally, we summarize the currently available approaches for the treatment of patients with PBL. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

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.

Radiographic features of pleural effusions in pulmonary embolism

A prospective analysis of 155 patients with pulmonary embolism was undertaken to describe the radiographic characteristics of associated pleural effusions and related abnormalities. Approximately one half of these patients had pleural effusions. Patients with other potential causes of effusion, such as heart failure, pneumonia, or cancer, were eliminated from further analysis. In the remaining 62 patients, radiographic evidence of pulmonary infarction accompanied pleural effusions in one half of the cases. One third of patients with parenchymal consolidation had no evidence of effusion. Atelectasis and other nonspecific radiographic abnormalities occurred in less than one fifth of the cases. Typically, pleural effusions were small and unilateral, appeared soon after symptoms of thromboembolism began, and tended to reach their maximal size very early in the course of the disorder. Pulmonary infarction was associated with larger effusions that cleared more slowly and were more often bloody in appearance on thoracentesis. Chest pain occurred in all but one patient and was a valuable diagnostic clue. Pain and pleural effusions were always ipsilateral and almost always unilateral, but neither correlated well with the presence or time course of infarction. Effusions that were delayed in onset or that enlarged late in the course were associated with recurrent pulmonary embolism or superinfection. These radiographic features may be helpful in the diagnosis and management of pulmonary embolism

We describe a primary periosteal lymphoma that involved only the periosteum without affecting the adjacent medulla or the regional lymph nodes. No other lymphomatous foci were found in either the distant lymph nodes or viscera. This unusual presentation simulates the imaging appearance of surface lesions of bone, namely benign and malignant tumors, and departs from the typical appearance of primary lymphoma of bone. Therefore, this rare type of lymphoma should be considered in the differential diagnosis of surface bone lesions. (orig.)

Genetic analysis of radiation-induced mouse thymic lymphomas

Kominami, R.; Wakabayashi, Y.; Niwa, O.

2003-01-01

Mouse thymic lymphomas are one of the classic models of radiation-induced malignancies, and the model has been used for the study of genes involved in carcinogenesis. ras oncogenes are the first isolate which undergoes mutations in 10 to 30 % of lymphomas, and p16INK4a and p19ARF in the INK4a-ARF locus are also frequently inactivated. In our previous study, the inactivation of Ikaros, a key regurator of lymphoid system, was found in those lymphomas, and it was suggested that there are other responsible genes yet to be discovered. On the other hand, genetic predisposition to radiation-induced lymphoma often differs in different strains, and this reflects the presence of low penetrance genes that can modify the impact of a given mutation. Little study of such modifiers or susceptibility genes has been performed, either. Recent availability of databases on mouse genome information and the power of mouse genetic system underline usefulness of the lymphoma model in search for novel genes involved, which may provide clues to molecular mechanisms of development of the radiogenic lymphoma and also genes involved in human lymphomas and other malignancies. Accordingly, we have carried out positional cloning for the two different types of tumor-related genes. In this symposium, our current progress is presented that includes genetic mapping of susceptibility/ resistance loci on mouse chromosomes 4, 5 and 19, and also functional analysis of a novel tumor suppressor gene, Rit1/Bcl11b, that has been isolated from allelic loss (LOH) mapping and sequence analysis for γ -ray induced mouse thymic lymphomas

[Central nervous system relapse in diffuse large B cell lymphoma: Risk factors].

Sancho, Juan-Manuel; Ribera, Josep-Maria

2016-01-15

Central nervous system (CNS) involvement by lymphoma is a complication associated, almost invariably, with a poor prognosis. The knowledge of the risk factors for CNS relapse is important to determine which patients could benefit from prophylaxis. Thus, patients with very aggressive lymphomas (such as lymphoblastic lymphoma or Burkitt's lymphoma) must systematically receive CNS prophylaxis due to a high CNS relapse rate (25-30%), while in patients with indolent lymphoma (such as follicular lymphoma or marginal lymphoma) prophylaxis is unnecessary. However, the question about CNS prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL), the most common type of lymphoma, remains controversial. The information available is extensive, mainly based on retrospective and heterogeneous studies. There seems that immunochemotherapy based on rituximab reduces the CNS relapse rate. On the other hand, patients with increased serum lactate dehydrogenase plus more than one extranodal involvement seem to have a higher risk of CNS relapse, but a prophylaxis strategy based only on the presence of these 2 factors does not prevent all CNS relapses. Patients with involvement of testes or breast have high risk of CNS relapse and prophylaxis is mandatory. Finally, CNS prophylaxis could be considered in patients with DLBCL and renal or epidural space involvement, as well as in those cases with MYC rearrangements, although additional studies are necessary.

The epidemic of acquired immunodeficiency syndrome (AIDS) increased the incidence of lymphoma, particularly the non-Hodgkin's lymphoma. The lymphoma in immune deficient patients is usually high-grade, very aggressive and with poor prognostic. We report the radiologic characteristics of AIDS-related lymphoma in 19 patients and correlate with the literature. The disease was predominant in homosexual male patients, with mean age of 38 years. The radiological characteristics are nonspecific to differential diagnosis, but we must suspect of lymphoma. We found ring-enhanced lesions in the radiologic studies of central nervous system. Hylar and mediastinal lymphadenopath, nodules and alveolar infiltration were detected on thoracic examinations. Abdominal examinations showed hepatosplenomegaly, lymphadenopathy, hepatic focal lesions and thickneded with distorted mucosa in the alimentary tract. Bone involvement presented as focal and disseminated destructive lesions. (author)

Full Text Available We are reporting the case of a 58-year-old woman with history of bilateral silicone breast implants for cosmetic augmentation. At 2-year interval from receiving the breast implants, she presented with swelling of the right breast with associated chest wall mass, effusion around the implant, and axillary lymphadenopathy. Pathology confirmed breast implant-associated anaplastic large cell lymphoma (stage III, T4N2M0, using BIA-ALCL TNM staging and stage IIAE, using Ann-Arbor staging. The patient underwent bilateral capsulectomy and right partial mastectomy with excision of the right breast mass and received adjuvant CHOP chemotherapy and radiation to the right breast and regional nodes. Since completion of multimodality therapy, the patient has sustained remission on both clinical exam and PET/CT scan. We report this case and review of the literature on this rare form of lymphoma.

Growth arrest lines appear as dense sclerotic lines parallel to the growth plate of long bones on radiography. We describe the case of a 9-year-old female with growth arrest lines initially masquerading as lymphoma involvement on {sup 99m}Tc-MDP bone scintigraphy who had been treated with chemotherapy for non-Hodgkin's lymphoma about 3 years previously. Subsequent regional bone SPECT/CT clearly diagnosed the growth arrest lines, and retrograde review of previous bone scintigraphy demonstrated line migration in this patient. Growth arrest lines should be considered a possible diagnosis on bone scintigraphy, especially in the surveillance of children who have experienced severe childhood infections, malnutrition, immobilization, or treatment with immunosuppressive or chemotherapeutic drugs that may inhibit bone growth.

Malignant lymphoma has become an increasingly recognized problem in African lions (Panthera leo). Eleven African lions (9 male and 2 female) with clinical signs and gross and microscopic lesions of malignant lymphoma were evaluated in this study. All animals were older adults, ranging in age from 14 to 19 years. Immunohistochemically, 10 of the 11 lions had T-cell lymphomas (CD3(+), CD79a(-)), and 1 lion was diagnosed with a B-cell lymphoma (CD3(-), CD79a(+)). The spleen appeared to be the primary site of neoplastic growth in all T-cell lymphomas, with involvement of the liver (6/11) and regional lymph nodes (5/11) also commonly observed. The B-cell lymphoma affected the peripheral lymph nodes, liver, and spleen. According to the current veterinary and human World Health Organization classification of hematopoietic neoplasms, T-cell lymphoma subtypes included peripheral T-cell lymphoma (4/11), precursor (acute) T-cell lymphoblastic lymphoma/leukemia (2/11), chronic T-cell lymphocytic lymphoma/leukemia (3/11), and T-zone lymphoma (1/11). The single B-cell lymphoma subtype was consistent with diffuse large B-cell lymphoma. Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) testing by immunohistochemistry on sections of malignant lymphoma was negative for all 11 lions. One lion was seropositive for FeLV. In contrast to domestic and exotic cats, in which B-cell lymphomas are more common than T-cell lymphomas, African lions in this study had malignant lymphomas that were primarily of T-cell origin. Neither FeLV nor FIV, important causes of malignant lymphoma in domestic cats, seems to be significant in the pathogenesis of malignant lymphoma in African lions.

Full Text Available Objective: PMBCL is a distinct type of nonhodgkins lymphoma with specific clinicopathological features. To clarify clinical features, treatment alternatives and outcomes, we evaluated 28 Arab patients treated with chemotherapy or radiotherapy between 2006 and 2011. Patients and Methods: PMBCL lymphoma patients identified according to WHO classification and treated at KCCC between 2006 and 2011 were included in this study. Demographic and clinical data are presented as means or medians. Overall survival was estimated using the Kaplan-Meier method. Survival rates were compared using the log-rank test. A P < 0.05 was considered significant. Results: The median age of the patients was 31 years and the male to female ratio was 2:1. Majority of the patients (75% presented with stage I/II disease. Most had features of local extension like pleural effusion (18% and SVCO (39%. Only 11% of the patients had bone marrow involvement at presentation. 96% of the patients required biopsy from the mediastinal mass either by image guided core biopsy (75% or by surgical biopsy. Most patients were treated by RCHOP and involved field radiotherapy. Patients with positive PET scan after RCHOP chemotherapy received salvage chemotherapy and BEAM autologous marrow transplant. The five year OS for the entire group was 85% while the PFS was 73%. Patients who had PET scan for response evaluation had better OS [P = 0.013] and PFS [P = 0.039] when compared with those patients who received only radiotherapy based on CT scan evaluation. Conclusion: PMBCL is a specific lymphoma entity seen in the young with good survival. The role of PET scan for response evaluation and the type of consolidation therapy needs to be further clarified

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 pleural effusions had significantly higher incidence of long-term total mortality than those without pleural effusions (55% versus 23%, P 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.

Full Text Available HIV-associated lymphoproliferative disorders represent a heterogeneous group of diseases, arising in the presence of HIV-associated immunodeficiency. The overall prevalence of HIV-associated lymphoma is significantly higher compared to that of the general population and it continues to be relevant even after the wide availability of highly active antiretroviral therapy (HAART (1. Moreover, they still represent one of the most frequent cause of death in HIV-infected patients. Epstein–Barr virus (EBV, a γ-Herpesviruses, is involved in human lymphomagenesis, particularly in HIV immunocompromised patients. It has been largely implicated in the development of B-cell lymphoproliferative disorders as Burkitt lymphoma (BL, Hodgkin disease (HD, systemic non Hodgkin lymphoma (NHL, primary central nervous system lymphoma (PCNSL, nasopharyngeal carcinoma (NC. Virus-associated lymphomas are becoming of significant concern for the mortality of long-lived HIV immunocompromised patients, and therefore, research of advanced strategies for AIDS-related lymphomas is an important field in cancer chemotherapy. Detailed understanding of the EBV  lifecycle and related cancers at the molecular level is required for novel strategies of molecular-targeted cancer chemotherapy The linkage of HIV-related lymphoma with EBV infection of the tumor clone has several pathogenetic, prognostic and possibly therapeutic implications which are reviewed herein

A patient on RIPE therapy presenting with recurrent isoniazid-associated pleural effusions: a case report

2011-11-01

Full Text Available Abstract Introduction The clinical scenario of a new or worsening pleural effusion following the initiation of antituberculous therapy has been classically referred to as a 'paradoxical' pleural response, presumably explained by an immunological rebound phenomenon. Emerging evidence suggests that there also may be a role for a lupus-related reaction in the pathophysiology of this disorder. Case presentation An 84-year-old Asian man treated with isoniazid, along with rifampin, pyrazinamide and ethambutol for suspected extrapulmonary tuberculosis, presented with a recurrent pleural effusion, his third episode since the initiation of this therapy. The first effusion occurred one month after the start of treatment, without any prior evidence of pulmonary tuberculosis involvement. Follow-up testing, including thoracoscopic pleural biopsies, never confirmed tuberculosis infection. Further evaluation yielded serological evidence suggesting drug-induced lupus. No effusions recurred following the discontinuation of isoniazid, although other antituberculosis medications were continued. Conclusion The immunological rebound construct is inconsistent with the evolution of this case, which indicates rather that drug-induced lupus may explain at least some cases of new pleural effusions following the initiation of isoniazid.

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.

Background Fibrous tuberculous pleural effusion (TPE) represents common disease in tuberculous clinic. Medical thoracoscopy has been used to treat pleural empyema and shown promising outcomes, but data of its use in multiloculated and organized TPE remains limited to know. Methods The study was performed on 430 cases with TPE. The cases were divided into free-flowing, multiloculated effusion and organized effusion group. Each group was subdivided into two or three types of therapeutic approaches: ultrasound guided pigtail catheter, large-bore tube chest drainage and medical thoracoscopy. Patients with multiloculated or organized effusions received streptokinase, introduced into the pleural cavity via chest tubes. The successful effectiveness of the study was defined as duration of chest drainage, time from treatment to discharge days and no further managements. Results Patients with organized effusion were older than those with free-flowing effusion and incidence of organized effusion combined with pulmonary tuberculosis (PTB) was higher than those of multiloculated effusion and free-flowing effusion respectively. Positive tuberculosis of pleural fluid culture was higher in organized effusion than that in free-flowing effusion. Sputum positive for acid-fast bacillus (AFB) in organized effusion was higher than that in multiloculated effusion and free-flowing effusion. Medical thoracoscopy showed significant efficacy in the group of multiloculated effusion and organized effusion but free-flowing effusion. No chronic morbidity and mortality related to complications was observed. Conclusions Medical thoracoscopy was a safe and successful method in treating multiloculated and organized TPE.

Full Text Available Victoria Mary Lendrum CohenSt. Bartholomew’s and Moorfields Eye Hospital, London UKAbstract: Most lymphomas that involve the ocular adnexal structure are low grade, B cell, non-Hodgkin’s lymphomas. The treatment depends upon the grade and stage of the disease. High grade lymhoma requires treatment with systemic chemotherapy whereas the localized low grade (extranodal marginal zone lymphoma can be successfully managed with local radiotherapy. Chlamydia psittaci infection is associated with low grade ocular lymphoma; however there is wide geographic variation in the strength of this association. Blanket antibiotic therapy is not advised unless there is proof of an infective agent. The monoclonal antibody, rituximab, may be successful for CD20 positive lymphoma, although it is likely that rituximab will have better long-term results when used in combination with systemic chemotherapy.Keywords: ocular adnexal lymphoma, mucosa associated lymphoid tissue, extranodal marginal zone lymphoma, Chlamydia psittaci, rituximab, radiotherapy, chemotherapy

Additive manufacturing techniques may be utilized to construct effusion plates. Such additive manufacturing techniques may include defining a configuration for an effusion plate having one or more internal cooling channels. The manufacturing techniques may further include depositing a powder into a chamber, applying an energy source to the deposited powder, and consolidating the powder into a cross-sectional shape corresponding to the defined configuration. Such methods may be implemented to construct an effusion plate having one or more channels with a curved cross-sectional geometry.

CT, Magnetic Resonance, and 18F-Fluorodeoxyglucose Positron Emission Tomography/CT Imaging Features of Mucosa-Associated Lymphoid Tissue Lymphoma Involving Medial Rectus Muscle: A Case Report

International Nuclear Information System (INIS)

Lee, Sang Kwon; Choe, Mi Sun

2013-01-01

We report a case of mucosa-associated lymphoid tissue (MALT) lymphoma involving the medial rectus muscle in a 47-year-old man along with CT, MRI, 18 F-fluorodeoxy-glucose positron emission tomography/CT ( 18 F-FDG PET/CT), and pathologic features. The lesion was manifested as a fusiform enlargement isolated to the right medial rectus muscle with involvement of its tendinous insertion. The lesion was isoattenuating to the brain on non-enhanced CT images, showing as isointense to gray matter on fast spin echo T1- and T2-weighted images with fat saturation, and showed homogeneous enhancement on contrast-enhanced CT and MR images. The maximum stan- dardized uptake value on 18 F-FDG PET/CT was 4.9 g/mL. The results of histological and immunohistochemical examinations of the specimen obtained by biopsy of the right medial rectus muscle were consistent with MALT lymphoma. It should be noted that the extraocular muscle (EOM) is a rare location for the involvement of MALT lympho- ma, and MALT lymphoma of the EOM may mimic thyroid orbitopathy.

The purpose of this study was to investigate the distribution and frequency of temporomandibular joint (TMJ) effusion in magnetic resonance (MR) images of patients with disc displacements. On T2 weighted MR images of 148 TMJs taken from 74 patients presenting with TMJ pain and dysfunction, we assessed the cases showing TMJ effusion, defined as an amount of fluid that exceeded the maximum amount seen in a control group of asymptomatic volunteers. The amount of TMJ fluid was graded as: I (none or minimal), II (moderate), III (marked), and IV (extensive), according to a standard set by a reference. Disc displacement categories were also recorded. Of the 148 TMJs examined in this study, 52 joints (35.1%) presented with joint effusion, 24 (16.2%) showing bilateral joint effusion. 38 joints showed upper joint space effusion, and 3 showed lower joint space effusion, and 11 showed both upper and lower joint space effusion. 96 joints (64.9%) had grade I joint fluid, 27 (18.2%) grade II, 15 (10.1%) grade III, and 10 (6.8%) grade IV. 80.0% of the joints presenting with grade IV effusion showed disc displacement without reduction. Joint effusion was found not only in upper, but also in lower joint spaces. The higher the effusion grade, the greater the frequency of disc displacement without reduction.

We performed this study to evaluate the clinical significance and temporal changes of pleural effusion developed after the resection of hepatoma. We reviewed retrospectively follow-up chest radiographs of 97 patients who had undergone operation for hepatoma and had no radiologically demonstrable postoperative complications. The duration of pleural effusion was classified into five groups and the amount of pleural effusion at one week after operation was graded into four groups. Statistical significance of the relationship between the duration, amount of pleural effusion and five factors, which are location and size of tumor, age of the patients, methods of operation, and preoperative liver function, was studied respectively. Pleural effusion was developed in 63.9% (62/97) and the mean duration was 2.5 weeks. In 92% (52/56), pleural effusion disappeared spontaneously within four weeks. Patients who had hepatoma in upper portion of the right lobe developed more frequent pleural effusion which persisted longer, and was larger in amount at one week after operation(p<0.05). There were no statistically significant differences between pleural effusion and the other four factors. Pleural effusion following hepatoma surgery should not be regarded as a sign of post-operative complication, as it invariably disappears spontaneously within four weeks. Development of pleural effusion is considered to be caused by local irritation and disturbance of lymphatic flow at the diaphragm

Middle ear effusion has been reported to be associated with immune responses in patients with otitis media with effusion (OME). Although various cytokines are involved in immunologic responses in patients with OME, no study to date has assessed the involvement of the pro-inflammatory cytokines interleukin (IL)-17 and IL-22. This study analyzed the levels of expression of IL-17 and IL-22 in the middle ear effusion of patients with OME. Patients aged Effusion fluid samples were obtained during surgery and levels of IL-17 and IL-22 mRNAs assessed by real-time PCR. IL-17 and IL-22 mRNA levels were compared in patients with effusion fluid positive and negative for bacteria; in patients with and without accompanying diseases, recurrent disease, and re-operation; and relative to fluid characteristics. The study cohort included 70 pediatric patients, 46 boys and 24 girls, of mean age 4.31 ± 2.11 years. The levels of IL-17 and IL-22 mRNA were higher in patients with than without sinusitis, but only IL-22 mRNA levels differed significantly (p < 0.05). The level of IL-17 mRNA was significantly higher in patients who did than did not undergo T&A (p < 0.05). The level of IL-22 expression was significantly higher in mucoid and purulent middle ear fluid samples than in serous fluid samples (p < 0.05). IL-17 and IL-22 mRNAs are involved in the pathophysiology of OME and are significantly higher in subjects with than without accompanying diseases. Copyright © 2016 Elsevier Ireland Ltd.

We analyzed plain radiographic and computed tomographic (CT) features of 26 biopsy proven small cell lung cancer (SCLC). Eleven cases of non Hodgkin's lymphoma involving the thorax were also reviewed and compared with the small cell lung cancer for differential diagnostic clues. Centrally manifesting lymphadenopathy was the main findings of SCLC in both plain radiographs and CT. The most frequently involved lymph nodes were subcarinal, right lower paratracheal, left lower paratracheal, and right tracheobronchial node. The most difficult site to identify the lymphadenopathy with simple radiograph was subcarinal, paraesophageal, pulmonary ligamental, anterior mediastinal (group 6), and left upper paratracheal nodes CT scan revealed lymphadenopathy clearly in all of these Groups. Right lower paratracheal and subcarinal nodes were involved frequently in both SCLC's and lymphomas. Bilateral tracheobronchial and bilateral intrapulmonary nodes were involved more frequently in SCLC's while anterior mediastinal, upper paratracheal, and aorticopulmonary (AP) window nodes were involved predominantly in lymphomas. Cystic low attenuation, presumed necrosis lymphadenopathy, was noted in two cases of lymphomas but not found in SCLC's at all. In conclusion, the CT could detect involved lymphadenopathy in SCLC more accurately than plain radiograph and the sites of involved lymphadenopathy may give a differential diagnostic clue between SCLC and lymphoma

Background Pericardial effusion is still a common postoperative complication after open heart surgery with cardiopulmonary bypass. Pericardial effusion significantly prolongs the hospital stay and associated costs as well as affecting overall outcomes after open heart surgery in Hanoi Heart Hospital, a tertiary hospital in Vietnam with an annual volume of 1000 patients. This study aimed to investigate the clinical presentation, incidence, and risk factors of postoperative pericardial effusion, which may ensure better prevention of pericardial effusion and improvement in surgical outcomes after open heart surgery. Methods A cross-sectional study was performed on 1127 patients undergoing open heart surgery from January 2015 to December 2015. Results Thirty-six (3.19%) patients developed pericardial effusion. Of these, 16 (44.4%) had cardiac tamponade. Pericardial effusion occurred after valve procedures in 77.8% of cases. Pericardial effusion was detected after discharge in 47.2% of cases at a mean time of 18.1 ± 13.7 days. Univariate logistic regression analysis showed that age > 25 years, body surface area ≥ 1.28 m 2 , preoperative liver dysfunction, New York Heart Association class III/IV, left ventricular end-diastolic diameter z score ≥ 0.55, and postoperative anticoagulant use were associated with postoperative pericardial effusion. Multivariate logistic regression analysis showed that left ventricular end-diastolic diameter z score ≥ 0.55 was an independent risk factor for postoperative pericardial effusion. Conclusions Routine postoperative echocardiography is necessary to detect postoperative pericardial effusion. Increased left ventricular end-diastolic dimension is an independent predictor of postoperative pericardial effusion.

A pleural effusion is excess fluid that collects in the pleural cavity, the fluid-filled space that surrounds the lungs. Surplus amounts of such fluid can impair breathing by limiting the expansion of the lungs during inhalation. Measuring the fluid volume is indicative of the effectiveness of any treatment but, due to the similarity to surround regions, fragments of collapsed lung present and topological changes; accurate quantification of the effusion volume is a difficult imaging problem. A novel code is presented which performs conditional region growth to accurately segment the effusion shape across a dataset. We demonstrate the applicability of our technique in the segmentation of pleural effusion and pulmonary masses.

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.

To assess, in patients with diffuse large B-cell lymphoma (DLBCL), whether the low sensitivity of 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET) for bone marrow assessment may be explained by histological characteristics of the cellular infiltrate. From a prospective cohort of 110 patients with newly diagnosed aggressive lymphoma, 21 patients with DLBCL had bone marrow involvement. Pretherapeutic FDG-PET images were interpreted visually and semiquantitatively, then correlated with the type of cellular infiltrate and known prognostic factors. Of these 21 patients, 7 (33%) had lymphoid infiltrates with a prominent component of large transformed lymphoid cells (concordant bone marrow involvement, CBMI) and 14 (67%) had lymphoid infiltrates composed of small cells (discordant bone marrow involvement, DBMI). Only 10 patients (48%) had abnormal bone marrow FDG uptake, 6 of the 7 with CBMI and 4 of the 14 with DBMI. Therefore, FDG-PET positivity in the bone marrow was significantly associated with CBMI, while FDG-PET negativity was associated with DBMI (Fisher's exact test, p=0.024). There were no significant differences in gender, age and overall survival between patients with CBMI and DBMI, while the international prognostic index was significantly higher in patients with CBMI. Our study suggests that in patients with DLBCL with bone marrow involvement bone marrow FDG uptake depends on two types of infiltrate, comprising small (DBMI) or large (CBMI) cells. This may explain the apparent low sensitivity of FDG-PET previously reported for detecting bone marrow involvement. (orig.)

Molecular resemblance of an AIDS-associated lymphoma and endemic Burkitt lymphomas: Implications for their pathogenesis

Non-Hodgkin lymphoma is a common feature of AIDS. Approximately 30-40% of these tumors exhibit clinical features suggestive of endemic Burkitt lymphoma: they are aggressive malignancies that occur in association with Epstein-Barr virus infection, they arise in the setting of immunosuppression, and they carry t(8;14) translocations without detectable rearrangement of the MYC oncogene. To understand the molecular basis of these parallels, the authors analyzed a case of Epstein-Barr-positive AIDS-associated undifferentiated lymphoma. Southern blots show that the tumor exhibits immunoglobulin joining segment rearrangement but no rearrangement of the MYC oncogene. Cloning of the rearranged joining segment allowed the isolation of recombinant clones encompassing the translocation breakpoint, and sequencing of the translocation junction disclosed that the breakpoint is situated 7 base pairs from the chromosome 14 site involved in a previously described endemic Burkitt lymphoma translocation. Furthermore, the breakpoint is situated far from MYC on chromosome 8, a constant finding in endemic Burkitt lymphomas. That the molecular architecture of the translocation in this case is strikingly similar to previously analyzed translocations from endemic Burkitt lymphomas strongly suggests that common molecular mechanisms must be operative in the pathogenesis of these tumors

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 (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.

Primary colorectal lymphoma is a very uncommon disease; therefore, it has received little attention in the radiology literature. Moreover, imaging features of newly described pathologic subtypes have not been reported such as low-grade B-cell lymphoma arising from mucosa-associated lymphoid tissue and peripheral T-cell lymphoma that involves colorectal area. We retrospectively reviewed double-contrast barium enema and CT scans in the patients with primary colorectal lymphoma. In this article the radiologic appearances of primary colorectal lymphoma are categorized into focal lesion and diffuse lesion. Focal lesion includes polypoid mass, circumferential infiltration with smooth mucosal surface, circumferential infiltration with extensive ulceration, cavitary mass, mucosal nodularity, and mucosal fold thickening. Diffuse lesion includes diffuse ulcerative lesion and diffuse nodular lesion. Peripheral T-cell lymphomas that involve the colon manifested as either a diffuse or focal segmental lesion and showed extensive mucosal ulceration. These findings are similar to those of Crohn's disease or tuberculous colitis and are different from those of previously reported colorectal lymphoma. Low-grade B-cell lymphoma arising from mucosa-associated lymphoid tissue manifest as multiple mucosal nodularity. The imaging features of primary colorectal lymphoma are quite variable and overlap with other colonic pathology; however, it is important for radiologists to know the imaging features of primary colorectal lymphoma with their pathologic correlation.

Three hundred and fifty-two patients with carcinoma of the breast treated postoperatively with radiotherapy were analyzed for laterality and incidence of pleural effusion. A statistically significant increase in ipsilateral pleural effusions was noted in the entire group (p less than 0.0001). Thirty-three percent of the patients with chest wall recurrences developed ipsilateral effusions while only 4.5 percent of those who did not develop chest wall recurrences suffered ipsilateral effusions (p less than 0.001). The role of the chest wall lymphatics in the development of malignant pleural effusions is discussed

Azidothymidine Sensitizes Primary Effusion Lymphoma Cells to Kaposi Sarcoma-Associated Herpesvirus-Specific CD4+ T Cell Control and Inhibits vIRF3 Function.

Full Text Available Kaposi sarcoma-associated herpesvirus (KSHV is linked with the development of Kaposi sarcoma and the B lymphocyte disorders primary effusion lymphoma (PEL and multi-centric Castleman disease. T cell immunity limits KSHV infection and disease, however the virus employs multiple mechanisms to inhibit efficient control by these effectors. Thus KSHV-specific CD4+ T cells poorly recognize most PEL cells and even where they can, they are unable to kill them. To make KSHV-infected cells more sensitive to T cell control we treated PEL cells with the thymidine analogue azidothymidine (AZT, which sensitizes PEL lines to Fas-ligand and TRAIL challenge; effector mechanisms which T cells use. PELs co-cultured with KSHV-specific CD4+ T cells in the absence of AZT showed no control of PEL outgrowth. However in the presence of AZT PEL outgrowth was controlled in an MHC-restricted manner. To investigate how AZT sensitizes PELs to immune control we first examined BJAB cells transduced with individual KSHV-latent genes for their ability to resist apoptosis mediated by stimuli delivered through Fas and TRAIL receptors. This showed that in addition to the previously described vFLIP protein, expression of vIRF3 also inhibited apoptosis delivered by these stimuli. Importantly vIRF3 mediated protection from these apoptotic stimuli was inhibited in the presence of AZT as was a second vIRF3 associated phenotype, the downregulation of surface MHC class II. Although both vFLIP and vIRF3 are expressed in PELs, we propose that inhibiting vIRF3 function with AZT may be sufficient to restore T cell control of these tumor cells.

To determine through an analysis of the location of pleural effusion associated with ascites, as seen on abdominal CT scan, differences in the distribution of pleural effusion according to the etiology and distribution of ascites. We retrospectively evaluated 77 consecutive patients in whom abdominal CT scan revealed pleural effusion associated with ascites. Patients with history of surgery or trauma and those with clinically and radiologically diagnosed lung or pleural diseases were excluded. We compared the location of pleural effusion with the etiology and distribution of ascites. Forty-two patients were suffering from hepatobiliary diseases, mainly right dominant pleural effusion (26/42, 62%). Fourteen had intraperitoneal carcinomatosis with no significant difference between the frequency of right dominant (5/14, 36%) and of left dominant (6/14, 43%) pleural effusion. Eleven patients had pancreatic diseases, with mainly left dominant pleural effusion (6/11, 55%). Patients with right dominant ascites usually had right dominant pleural effusion (22/24, 92%) and those with left dominant ascites had left dominant pleural effusion (9/10, 90%). Ascites-associated pleural effusion correlated with the anatomical location of the etiology of ascites; its laterality was, in addition, usually the same as that of ascites.

To determine through an analysis of the location of pleural effusion associated with ascites, as seen on abdominal CT scan, differences in the distribution of pleural effusion according to the etiology and distribution of ascites. We retrospectively evaluated 77 consecutive patients in whom abdominal CT scan revealed pleural effusion associated with ascites. Patients with history of surgery or trauma and those with clinically and radiologically diagnosed lung or pleural diseases were excluded. We compared the location of pleural effusion with the etiology and distribution of ascites. Forty-two patients were suffering from hepatobiliary diseases, mainly right dominant pleural effusion (26/42, 62%). Fourteen had intraperitoneal carcinomatosis with no significant difference between the frequency of right dominant (5/14, 36%) and of left dominant (6/14, 43%) pleural effusion. Eleven patients had pancreatic diseases, with mainly left dominant pleural effusion (6/11, 55%). Patients with right dominant ascites usually had right dominant pleural effusion (22/24, 92%) and those with left dominant ascites had left dominant pleural effusion (9/10, 90%). Ascites-associated pleural effusion correlated with the anatomical location of the etiology of ascites; its laterality was, in addition, usually the same as that of ascites

We established a novel feline B-cell line, MS4, from the neoplastic pleural effusion of a cat with cutaneous B-cell lymphoma. Immunophenotype staining of the MS4 cells was positive for CD20, CD79α, and IgA and negative for CD3, CD4, CD5, CD8α, CD18, CD21, CD22, IgM, IgG, Ig light chain, and MHC class II. PCR analysis for immunoglobulin heavy chain gene rearrangements revealed a monoclonal rearrangement, whereas no clonal rearrangement of the T-cell receptor γ gene was detected. Southern blotting with an exogenous feline leukemia virus (FeLV) U3 probe revealed no integration of exogenous FeLV provirus. The MS4 cell line is the first FeLV-negative feline B-cell lymphoma cell line, and may be used to investigate the pathogenesis of spontaneously occurring feline lymphoma and the development of new therapies.

Fluoro-deoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) is superior to iliac bone marrow biopsy (iBMB) for detection of bone marrow involvement (BMI) in staging of Hodgkin's lymphoma (HL). The present study aims to characterize the patterns and distribution of BMI in HL as determined by FDG-PET/CT. Reports of FDG-PET/CT studies performed for staging of HL were reviewed. BMI was defined as positive iBMB and/or foci of pathological FDG uptake in the skeleton that behaved in concordance with other sites of lymphoma in studies following chemotherapy. Number of FDG uptake foci, their specific location in the skeleton and the presence of corresponding lesions in the CT component of the study, and stage according to the Ann Arbor staging system, were recorded. The study included 473 patients. iBMB was performed in 336 patients. Nine patients had positive iBMB (9/336, 3 %). Seventy-three patients (73/473, 15 %) had FDG-PET/CT-defined BMI. The BM was the only extranodal site of HL in 52/473 patients (11 %). Forty-five patients had three or more foci of pathological skeletal FDG uptake (45/73, 62 %). Sixty-four patients (64/73, 88 %) had at least one uptake focus in the pelvis or vertebrae. In 60 patients (60/73, 82 %), the number of skeletal FDG uptake foci without corresponding CT lesions was equal to or higher than the number of foci with morphological abnormalities. FDG-PET/CT demonstrated BMI in 15 % of patients with newly diagnosed HL. Diagnosis of BMI in HL by FDG-PET/CT was more sensitive than iBMB with potential upstage in 11 % of patients. The most common pattern of FDG-PET/CT BMI was multifocal (at least three foci) skeletal FDG uptake, with at least one focus in the pelvis or vertebrae and no corresponding CT lesions. (orig.)

Clinical response to a lomustine/cytarabine-based chemotherapy protocol in a case of canine large granular lymphocyte T-cell lymphoma with spinal involvement

Full Text Available A 7-year-old, female neutered cross-breed dog was referred to our institution with a history of progressive hind limb weakness, which then progressed to paraplegia. An MRI of the spine revealed severe meningeal infiltrate consistent with lymphoma involvement, located at the level of L2-L7 with concurrent lymph node enlargement and abnormal bone marrow. Abdominal ultrasonography also identified changes in the spleen and confirmed enlargement of the lumbar aortic lymph node. Cytology of lymph nodes and spleen confirmed a high-grade lymphoma with features of a large granular lymphocyte (LGL variant; PCR for antigen receptor re-arrangements (PARR was positive for a clonal T-cell receptor rearrangement. The dog was started on a chemotherapy protocol with lomustine and cytarabine incorporation and had a rapid improvement in neurological status. Chemotherapy was continued until relapse and rescue treatment used at that time. The dog was euthanased at the time of recurrence of neurological signs, 195 days since medical treatment was started. This case report suggests that combination chemotherapy may be of use when treating LGL lymphoma with spinal involvement and survival time may potentially exceed 6 months.

Assay of cells in pleural effusion (PE) is an important means of disease diagnosis. Conventional cytology of effusion samples, however, has low sensitivity and depends heavily on the expertise of cytopathologists. We applied a polarization diffraction imaging flow cytometry method on effusion cells to investigate their features. Diffraction imaging of the PE cell samples has been performed on 6000 to 12000 cells for each effusion cell sample of three patients. After prescreening to remove images by cellular debris and aggregated non-cellular particles, the image textures were extracted with a gray level co-occurrence matrix (GLCM) algorithm. The distribution of the imaged cells in the GLCM parameters space was analyzed by a Gaussian Mixture Model (GMM) to determine the number of clusters among the effusion cells. These results yield insight on textural features of diffraction images and related cellular morphology in effusion samples and can be used toward the development of a label-free method for effusion cells assay.

Full Text Available A 82-year-old patient with dyspnea and a recurrent history of pleural effusion was admitted into our unit. He performed a Chest computed tomography showing right pleural effusion. Video-assisted thoracoscopy (VATS exploratory showed parietal pleural thickening of adipose tissue. The surgical procedure consisted, therefore, in the execution of multiple biopsies of the parietal pleura which appeared covered, on the whole surface, by islands of adipose tissue, without macroscopic pathological aspects. After the procedure was performed pleurodesis with talc. The definitive histological examination consisted of normal mesothelial cells surrounded by fatty tissue infiltrated by small lymphocytes in a patient without skin lesions or visceral or systemic signs of inflammatory involvement of the adipose tissue. We reported a rare case of idiopathic pleural panniculitis with recurrent pleural effusion not associated with Weber-Christian disease.

The present authors, since the installation of the CT scanner in Sept., 1976, have conducted an investigation of 14 adult subdural effusion cases arising from head injury which were available for a follow-up by CT scanning. These cases were examined in the first 13 months after installation. Under CT scanning, subdural effusion was recognized as a low-density area of the subdural space. Our findings indicate that, in spite of the fact that it is a subdural collection, only a limited shift of the midline structure was seen; further, the shrinking of the lateral ventricles of the effusion side was also limited. Judging from the CT findings, the neurological signs and the clinical course, the subdural effusions of the 14 cases could be classified into 2 types: (I) the minimal neurological deficit type and (II) the contusion-effusion type. Representative cases of the above are given, and, in addition, indications of surgery are also mentioned. We further state that, since the subdural effusion cases come under Type I and are characterized by the minimal neurological deficit, in many cases they are apt to be overlooked: hence, the application of CT scanning with special regard to such cases was stressed. In order to differentiate chronic subdural hematoma from subdural effusion under CT scanning, a comparative CT study was made using 20 cases of chronic subdural hematoma, and the difference in CT findings from those of subdural effusion is reported.

One Patient, Two Uncommon B-Cell Neoplasms: Solitary Plasmacytoma following Complete Remission from Intravascular Large B-Cell Lymphoma Involving Central Nervous System

Directory of Open Access Journals (Sweden)

Joycelyn Lee

2014-01-01

Full Text Available Second lymphoid neoplasms are an uncommon but recognized feature of non-Hodgkin’s lymphomas, putatively arising secondary to common genetic or environmental risk factors. Previous limited evaluations of clonal relatedness between successive mature B-cell malignancies have yielded mixed results. We describe the case of a man with intravascular large B-cell lymphoma involving the central nervous system who went into clinical remission following immunochemotherapy and brain radiation, only to relapse 2 years later with a plasmacytoma of bone causing cauda equina syndrome. The plasmacytoma stained strongly for the cell cycle regulator cyclin D1 on immunohistochemistry, while the original intravascular large cell lymphoma was negative, a disparity providing no support for clonal identity between the 2 neoplasms. Continued efforts atcataloging and evaluating unique associations of B-cell malignancies are critical to improving understanding of overarching disease biology in B-cell malignancies.

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).

Pericardial effusion in pulmonary arterial hypertension

Science.gov (United States)

2013-01-01

Abstract Pulmonary arterial hypertension (PAH) is a serious condition that can lead to right heart failure and death. Pericardial effusion in PAH is associated with significant morbidity and mortality, and its pathogenesis is complex and poorly understood. There are few data on the prevalence of pericardial effusion in PAH, and more importantly, the management of pericardial effusion is controversial. Current literature abounds with case reports, case series, and retrospective studies that have limited value for assessing this association. Hence, we summarize the available evidence on this ominous association and identify areas for future research. PMID:24618534

To validate the accuracy of previously published equations that estimate pleural effusion volume using ultrasonography. Only equations using simple measurements were tested. Three measurements were taken at the posterior axillary line for each case with effusion: lateral height of effusion ( H ), distance between collapsed lung and chest wall ( C ) and distance between lung and diaphragm ( D ). Cases whose effusion was aspirated to dryness were included and drained volume was recorded. Intra-class correlation coefficient (ICC) was used to determine the predictive accuracy of five equations against the actual volume of aspirated effusion. 46 cases with effusion were included. The most accurate equation in predicting effusion volume was ( H  +  D ) × 70 (ICC 0.83). The simplest and yet accurate equation was H  × 100 (ICC 0.79). Pleural effusion height measured by ultrasonography gives a reasonable estimate of effusion volume. Incorporating distance between lung base and diaphragm into estimation improves accuracy from 79% with the first method to 83% with the latter.

We report a case of mucosa-associated lymphoid tissue (MALT) lymphoma involving the medial rectus muscle in a 47-year-old man along with CT, MRI, 18 F-fluorodeoxy-glucose positron emission tomography/CT ( 18 F-FDG PET/CT), and pathologic features. The lesion was manifested as a fusiform enlargement isolated to the right medial rectus muscle with involvement of its tendinous insertion. The lesion was isoattenuating to the brain on non-enhanced CT images, showing as isointense to gray matter on fast spin echo T1- and T2-weighted images with fat saturation, and showed homogeneous enhancement on contrast-enhanced CT and MR images. The maximum stan- dardized uptake value on 18 F-FDG PET/CT was 4.9 g/mL. The results of histological and immunohistochemical examinations of the specimen obtained by biopsy of the right medial rectus muscle were consistent with MALT lymphoma. It should be noted that the extraocular muscle (EOM) is a rare location for the involvement of MALT lympho- ma, and MALT lymphoma of the EOM may mimic thyroid orbitopathy.

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.

Full Text Available Objectives. Chronic pericardial effusion may be challenging in terms of diagnosis and treatment. Specific laboratory parameters predicting the frequency and severity of recurrences after initial drainage of pericardial effusion are lacking. Materials and Methods. Pericardial fluid (PF and serum (SE samples from 30 patients with chronic pericardial effusion (PE who underwent pericardiocentesis and pericardioscopically guided pericardial biopsy were compared with SE and PF samples from 26 control patients. The levels of antimyolemmal (AMLA and antifibrillary antibodies (AFA in PE and SE from patients with pericardial effusion as well as PF and SE from controls were determined and compared. Results. AMLAs and AFAs in PF and SE were significantly higher in patients with chronic pericardial effusion than in the control group (AMLAs: p = 0,01 for PF and p = 0,004 for serum; AFAs: p < 0,001 for PF and p = 0,003 for serum. Patients with recurrence of PE within 3 months after pericardiocentesis had significantly higher levels of AMLAs in SE (p = 0,029 than patients without recurrence of PE. Conclusions. The identification of elevated anticardiac antibodies in PE and SE indicates increased immunological reactivity in chronic pericardial effusion. High titer serum levels of AMLAs also correlate with recurrence of pericardial effusion.

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.

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.

Intraarticular volume and clearance in human synovial effusions

1985-01-01

Intraarticular volumes were measured by radiolabeled albumin (RISA) distribution in chronic knee effusions from 11 rheumatoid arthritis patients and 9 osteoarthritis patients. Volumes of synovial fluid obtained at joint aspiration were substantially less than those found by RISA dilution. Up to 24 hours was needed for full distribution of RISA throughout the intraarticular compartment. Measured 123I and RISA radioactivity over the knee described monoexponential rate constants, lambda (minute-1). The clearance of 123I and RISA from synovial effusions was derived by the formulation volume (ml) X lambda (minute-1) = clearance (ml/minute). RISA clearance in rheumatoid effusions was significantly greater than that found in osteoarthritis effusions. Intraarticular volume and isotope clearance were easily quantified and provide measures for further evaluating the microvascular physiology of synovial effusions

Localized nasal cavity, sinus, and massive bilateral orbital involvement by human T cell leukemia virus 1 adult T cell lymphoma, with epidermal hypertrophy due to mite infestation

2010-10-01

Full Text Available HTLV1 adult T cell lymphoma occurs tends to be widely disseminated and aggressive, with only brief responses to chemotherapy. Aside from cervical adenopathy, involvement of head and neck structures is uncommon and orbital involvement rare. We report a case of nasal cavity HTLV lymphoma with massive bilateral orbital involvement and proptosis, resulting in complete left and partial right eye amaurosis. No other sites of disease were found. Response to chemotherapy was rapid and complete, with almost complete restoration of vision and oculo-motor function; the patient has remained in remission for one year. An associated problem was striking bilateral hypertrophic, hyperkeratotic eyelid and breast lesions due to mite infestation.

Forty cases of ovarian lymphoma and two of extramedullary leukemia were examined with emphasis on histologic types correlated with age, modes of presentation, operative findings, including frequency of bilaterality and omental spread, clinical course following therapy, and problems in differential diagnosis. Although most cases were referred with diagnoses other than lymphoma (granulosa cell tumor or dysgerminoma, occasionally anaplastic tumor, Krukenberg tumor, or metastatic breast carcinoma), utilization of sections cut at 4 mu and stained with hematoxylin and eosin, or sections stained by the methyl green pyronine (MGP), naphthol-ASD esterase (NASD) or periodic acid-Schiff (PAS) methods helped bring out the lymphoid or hematopoietic nature of the cells. Sixteen patients were under 20 years of age. They had small noncleaved cell lymphoma (undifferentiated Burkitt's and non-Burkitt's, 10 cases), diffuse immunoblastic large cell lymphoma (4 cases), or acute granulocytic leukemia (2 cases). Twenty-six patients were 29 to 74 years of age and had diffuse large cell lymphoma (10 cases), diffuse immunoblastic large cell lymphoma (9 cases), follicular (nodular) lymphoma (6 cases) or small noncleaved cell lymphoma (1 case). Pain with an abdominal or pelvic mass was the most common presentation. Nine tumors were discovered during investigation of other gynecologic complaints. At laparotomy, the tumors in 55% of cases involved both ovaries, and in 64% also involved extragonadal sites (usually omentum, fallopian tubes, or lymph nodes). Seventeen patients had tumor affecting one ovary, seven of these without any evidence of extragonadal spread. Forty-two percent (15) of 37 patients with follow-up were alive after 2 years. Only nine patients survived more than 5 years; two subsequently died of lymphoma. Favorable prognostic features included: (1) FIGO stage IA; (2) unilateral ovarian involvement; (3) focal involvement of one ovary; and (4) follicular (nodular) lymphoma.

Castleman disease (CD) is a rare poorly understood lymphoproliferative disorder. Pediatric onset CD has been reported before. However, most of them have benign unicentric pattern. Multicentric CD (MCD) is quite rare in children. Herein, we report a 13-year-old adolescent boy with MCD of the hyaline vascular variant presenting with pleural and pericardial effusion, which is an uncommon presentation. MCD should be considered in the differential diagnosis of pleural and/or pericardial effusion with unexplained lymph nodes in children. What is Known •Pediatric Castleman disease (CD) most commonly occurs in the unicentric form, which typically is asymptomatic and cured by lymph node excision. •The diagnosis of MCD can be difficult owing to the heterogeneity of presentation and potential for nonspecific multisystem involvement. What is New •A 13-year-old adolescent boy was diagnosed with MCD of the hyaline vascular variant presenting with pleural and pericardial effusion, which is an uncommon presentation. •In a pediatric patient with fever, pleural-pericardial effusion and multiple lymph nodes, MCD should be considered in differantial diagnosis.

Full Text Available Primary non-Hodgkins lymphoma of the uterine cervix is a very rare diagnosis. A 54-year-old woman presented with a 3-month history of postmenopausal bleeding per vaginum. On examination, a friable, fungating lesion was seen on the cervix. Histology revealed a CD 20 positive high-grade non-Hodgkin’s diffuse large B cell lymphoma from cervical biopsies and endometrial curettage. She was diagnosed as stage IE after workup and subsequently treated with six cycles of R-CHOP chemotherapy followed by radiotherapy of the involved field.

MYC translocation-negative classical Burkitt lymphoma cases: an alternative pathogenetic mechanism involving miRNA deregulation

DEFF Research Database (Denmark)

Leucci, E; Cocco, M; Onnis, A

2008-01-01

at the standardization of FISH procedures in lymphoma diagnosis, we found that five cases out of 35 classic endemic BLs were negative for MYC translocations by using a split-signal as well as a dual-fusion probe. Here we investigated the expression pattern of miRNAs predicted to target c-Myc, in BL cases, to clarify...... whether alternative pathogenetic mechanisms may be responsible for lymphomagenesis in cases lacking the MYC translocation. miRNAs are a class of small RNAs that are able to regulate gene expression at the post-transcriptional level. Several studies have reported their involvement in cancer...

Sai Baba, M.

1997-01-01

The Knudsen effusion mass spectrometric method for the determination of vapour pressures and thermodynamic properties is described. The aim of the article is to give a general introduction to the method rather than to give a critical review of the technique. The latest developments in this area of research are reviewed by the peers in the field during the triennial international mass spectrometric conferences. The Knudsen effusion mass spectrometric method is being applied for thermodynamic measurements. In recent times, laser vaporisation mass spectrometric methods have emerged as a source of determination of vapour pressures at very high temperatures and beyond the pressure regime far exceeding Knudsen effusion range

The purposes of this study were to evaluate the relationship between correlation of MR joint effusion of the temporomandibular joint and disk position, to evaluate the relationship between joint effusion and aging, and to assess the frequency of MR joint effusion of bilateral temporomandibular joints. The temporomandibular joints of 192 patients with clinical symptoms of temporomandibular joint disorders were imaged bilaterally using high field, surface-coil MR imaging. Oblique sagittal and coronal proton density-weighted and T2-weighted images were obtained. Imaging findings of joint effusion were correlated with disk position, aging, and bilateral temporomandibular joints. MR showed effusion in 4% of the joints with normal superior disk position, 36% of the joints with disk displacement with reduction, and 45% of the joints with disk displacement without reduction. There were significant differences in the incidence of joint effusion between normal disk position and anterior disk displacement with or without reduction. Younger patients less than 40 years were significant higher the incidence of joint effusion than those of older patients. A significant association was seen between joint effusion and aging. MR showed effusion in 17% of the unilateral temporomandibular joint, 24% of the bilateral temporomandibular joints. There was no significant difference between unilateral and bilateral case. These results indicated that joint effusion using MR imaging was associated with varied temporomandibular joint pathologic states. (author)

tuberculosis, 21 with inflammation and 1 with blood vessel malformation). FDG DHTC found the positive primary lung lesions in 37 of 38 patients with lung cancer, and was negative in 1 squamous cell carcinoma patient who had a atelectasis whose lesion size was 12 mm in diameter. FDG DHTC found false positive in 16 of 72 patients with benign diseases (14 with tuberculosis and 2 with inflammation). The sensitivity, specificity and accuracy of FDG DHTC in detecting lung cancer in patients with suspected malignant pleural effusion or malignant atelectasis were 97%, 78% and 85%, respectively. 30 patients with lung cancer and a pleural effusion, FDG DHTC correctly detected the presence of malignant pleural effusion and malignant pleural involvement in 18 of 21 patients and excluded malignant pleural effusion or pleural metastatic involvement in 8 of 9 patients (sensitivity, specificity and accuracy of 86%, 89% and 87% respectively). The mediastinal lymph node metastasis was found in 6 of these 21 patients with malignant pleural effusions. Conclusions: FDG DHTC imaging is a highly accurate and reliable noninvasive test in finding primary lung malignant lesions in patients with pleural effusion or atelectasis on CT scanning. Active tuberculosis or tuberculo-pleurisy is the main reason of false positivity on FDG DHTC imaging. FDG DHTC is also useful to differentiate malignant from benign pleural effusion in patients with lung cancer. (authors)

Cell origins and diagnostic accuracy of interleukin 27 in pleural effusions.

Directory of Open Access Journals (Sweden)

Wei-Bing Yang

Full Text Available The objective of the present study was to investigate the presence of interleukin (IL-27 in pleural effusions and to evaluate the diagnostic significance of pleural IL-27. The concentrations of IL-27 were determined in pleural fluids and sera from 68 patients with tuberculous pleural effusion, 63 malignant pleural effusion, 22 infectious pleural effusion, and 21 transudative pleural effusion. Flow cytometry was used to identify which pleural cell types expressed IL-27. It was found that the concentrations of pleural IL-27 in tuberculous group were significantly higher than those in malignant, infectious, and transudative groups, respectively. Pleural CD4(+ T cells, CD8(+ T cells, NK cells, NKT cells, B cells, monocytes, macrophages, and mesothelial cells might be the cell sources for IL-27. IL-27 levels could be used for diagnostic purpose for tuberculous pleural effusion, with the cut off value of 1,007 ng/L, IL-27 had a sensitivity of 92.7% and specificity of 99.1% for differential diagnosing tuberculous pleural effusion from non-tuberculous pleural effusions. Therefore, compared to non-tuberculous pleural effusions, IL-27 appeared to be increased in tuberculous pleural effusion. IL-27 in pleural fluid is a sensitive and specific biomarker for the differential diagnosing tuberculous pleural effusion from pleural effusions with the other causes.

Central nervous system (CNS) relapse occurs in around 5% of diffuse large B-cell lymphoma (DLBCL) cases. No biomarkers to identify high-risk patients have been discovered. We evaluated the expression of lymphocyte-guiding chemokine receptors in systemic and CNS lymphomas. Immunohistochemical staining for CXCR4, CXCR5, CCR7, CXCL12, and CXCL13 was performed on 89 tissue samples, including cases of primary central nervous system lymphoma (PCNSL), secondary CNS lymphoma (sCNSL), and systemic DLBCL. Also, 10 reactive lymph node samples were included. Immunoelectron microscopy was performed on two PCNSLs, one sCNSL, one systemic DLBCL, and one reactive lymph node samples, and staining was performed for CXCR4, CXCR5, CXCL12, and CXCL13. Chi-square test was used to determine correlations between clinical parameters, diagnostic groups, and chemokine receptor expression. Strong nuclear CXCR4 positivity correlated with systemic DLBCL, whereas strong cytoplasmic CXCR5 positivity correlated with CNS involvement (P = 0.003 and P = 0.039). Immunoelectron microscopy revealed a nuclear CXCR4 staining in reactive lymph node, compared with cytoplasmic and membranous localization seen in CNS lymphomas. We found that CNS lymphoma presented a chemokine receptor profile different from systemic disease. Our findings give new information on the CNS tropism of DLBCL and, if confirmed, may contribute to more effective targeting of CNS prophylaxis among patients with DLBCL. © 2015 John Wiley & Sons A/S.

Primary Hepatosplenic Large B-Cell Lymphoma

Directory of Open Access Journals (Sweden)

M.R. Morales-Polanco

2008-03-01

Full Text Available Diffuse large B-cell lymphoma is the most common form of lymphoma. It usually begins in the lymph nodes; up to 40% may have an extranodal presentation. According to a definition of primary extranodal lymphoma with presentation only in extranodal sites, there are reports of large B-cell lymphomas limited to liver or spleen as separate entities, and to date there have been only three documented cases of primary hepatosplenic presentation. This paper reports a fourth case. Due to a review of the literature and the clinical course of the case reported, we conclude that primary hepatosplenic large B-cell lymphoma has been found predominantly in females older than 60 years. The patients reported had <2 months of evolution prior to diagnosis, prominent B symptoms, splenomegaly in three and hepatomegaly in two, none with lymph node involvement. All had thrombocytopenia and abnormal liver function tests; three had anemia and elevated serum lactic dehydrogenase levels, two with hemophagocytosis in bone marrow. Because of the previously mentioned data, it can be stated that primary hepatosplenic lymphoma is an uncommon and aggressive form of disease that requires immediate recognition and treatment.

Tuberculous Pleural Effusion

Cohen, Leah A.; Light, Richard W.

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

Lymphomas are classified based on the normal counterpart, or cell of origin, from which they arise. Because lymphocytes have physiologic immune functions that vary both by lineage and by stage of differentiation, the classification of lymphomas arising from these normal lymphoid populations is complex. Recent genomic data have contributed additional complexity. Areas covered: Lymphoma classification follows the World Health Organization (WHO) system, which reflects international consensus and is based on pathological, genetic, and clinical factors. A 2016 revision to the WHO classification of lymphoid neoplasms recently was reported. The present review focuses on B-cell non-Hodgkin lymphomas, the most common group of lymphomas, and summarizes recent changes most relevant to hematologists and other clinicians who care for lymphoma patients. Expert commentary: Lymphoma classification is a continually evolving field that needs to be responsive to new clinical, pathological, and molecular understanding of lymphoid neoplasia. Among the entities covered in this review, the 2016 revision of the WHO classification particularly impact the subclassification and genetic stratification of diffuse large B-cell lymphoma and high-grade B-cell lymphomas, and reflect evolving criteria and nomenclature for indolent B-cell lymphomas and lymphoproliferative disorders.

The pleural effusion is defined as the abnormal accumulation of liquid in the pleural space that produces to itself for increase in the production or decrease of the drainage, common reasons in clinics disorders. Inside the reasons of the increase of the production we can enunciate an increase of the capillary pleural permeability, decrease of the oncotic pressure capillary and increase of the hydrostatic capillary pressure, there are less clear the reasons of the decrease of the drainage but are outlined the alteration of the lymphatic pleural contractibility , infiltration of vessels and lymphatic nodules for neoplasia diseases and alterations to pleural level that they should prevent that the this liquid touch the lymphatic pores. The objective of this review is the analysis of the physiological bases of the pleura and the production of the pleural liquid, the physiological aspects of the pleural effusion, the approach of the diagnose and the medical and surgical managing of the same one for the different reasons that produce it.

Acute pancreatitis is a rare initial presentation of non-Hodgkin lymphoma with few reported cases described in older adults and even fewer in children. MRI features of Burkitt lymphoma of the pancreas are sparse in the radiologic literature. We present a 6-year-old boy who presented with pancreatitis and obstructive jaundice, which was the result of Burkitt lymphoma of the pancreas. The imaging findings of pancreatic involvement of Burkitt lymphoma on MRI are discussed and the contributory role of the radiologist in guiding the appropriate clinical work-up of this disease is highlighted.

Advances in diagnostic imaging technology, especially functional imaging modalities like positron emission tomography (PET), have significantly influenced the staging and treatment approaches used for pediatric Hodgkin's lymphoma. Today, the majority of children and adolescents diagnosed with Hodgkin's lymphoma will be cured following treatment with noncross-resistant combination chemotherapy alone or in combination with low-dose, involved-field radiation. This success produced a greater appreciation of long-term complications related to radiation, chemotherapy, and surgical staging that prompted significant changes in staging and treatment protocols for children and adolescents with Hodgkin's lymphoma. Contemporary treatment for pediatric Hodgkin's lymphoma uses a risk-adapted approach that reduces the number of combination chemotherapy cycles and radiation treatment fields and doses for patients with localized favorable disease presentation. Advances in diagnostic imaging technology have played a critical role in the development of these risk-adapted treatment regimens. The introduction of computed tomography (CT) provided an accurate and non-invasive modality to define nodal involvement below the diaphragm that motivated the change from surgical to clinical staging. The introduction of functional imaging modalities, like positron emission tomography (PET) scanning, provided the means to correlate tumor activity with anatomic features generated by CT and modify treatment based on tumor response. For centers with access to this modality, PET imaging plays an important role in staging, evaluating tumor response, planning radiation treatment fields, and monitoring after completion of therapy for pediatric Hodgkin's lymphoma.

Full Text Available Abstract Introduction Breast involvement by non-Hodgkin lymphoma is particularly rare in men. We describe the case of a patient with a rapidly growing, painless gynecomastia-like nodule in the left breast. On ultrasonography, the nodule was suspicious for breast carcinoma. Case presentation A breast biopsy from a 54-year-old Caucasian man showed the morphoimmunophenotypical features of grade 3 follicular lymphoma. Moreover, fluorescence in situ hybridization analysis showed a t(14,18 translocation suggesting breast involvement by a systemic lymphoma rather than a primary breast lymphoma. The histological diagnosis was subsequently confirmed after nodule excision. Mediastinal and abdominal node involvement was then identified on computed tomography and positron emission tomography scans during staging examinations. Our patient was treated with chemotherapy. After three years our patient experienced a right retro-areolar relapse. He then received two further cycles of chemotherapy but developed a myeloid acute leukemia and, as a result of this, he subsequently died. Conclusions The rarity of breast lymphomas, especially in men, and the problems related to the therapeutic choices with these tumors require molecular techniques in association with classical histological diagnosis.

A 12-year-old female spayed Borzoi dog was referred for heart failure. Emergency room thoracic and abdominal ultrasound showed a large volume of pleural effusion with mild peritoneal effusion and an abdominal mass. Pleural fluid analysis classified the effusion as exudative. A complete ultrasound revealed mild peritoneal effusion and decreased blood flow to the right liver lobe. Other causes of bicavitary effusion were ruled out based on blood work, ultrasound, echocardiogram, and computed tomography. The patient was taken to surgery and diagnosed with caudate liver lobe torsion and had a liver lobectomy. At the 2-week postoperative recheck, the patient was doing well and there was complete resolution of the pleural effusion. Liver lobe torsion is a rare occurrence in dogs and can be difficult to diagnose. Clinical signs are nonspecific for liver lobe torsion and patients may present in respiratory distress with significant pleural fluid accumulation. When assessing patients with pleural and peritoneal effusion, liver lobe torsion should be considered as a differential diagnosis.Keywords: pleural effusion, peritoneal effusion, hepatic torsion

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.

Peritoneal spread of non-Hodgkin lymphoma is rare: fewer than three percent of persons afflicted with this disease develop peritoneal spread. Pericardial involvement by non-Hodgkin lymphoma is equally rare. We report an instance of peritoneal and pericardial spread in a patient with non-Hodgkin lymphoma that was detected only by CT scan. The peritoneal lesions were not visible by ultrasound examination. A pertinent review of the literature is presented. (author)

The incidence of posttransplantation lymphoproliferative disorders (PTLDs) has increased in recent years. Although rare, various types of T-cell lymphoma have been reported and their association with Epstein-Barr virus (EBV) has been compared with B-cell PTLDs. We report a case of splenic peripheral T-cell lymphoma occurring in a 47-yr-old male patient 7 yr after renal allograft transplantation. The spleen showed sinusoidal proliferation of focal CD30 positive, large, atypical lymphoid cells. Positivity for CD3 and cytolytic granule-associated proteins was also demonstrated in the tumor cells, while anaplastic large cell lymphoma kinase (ALK) and CD8 were not expressed. Strong nuclear signals for EBV mRNA were noted by EBER1 in situ hybridization. A molecular genetic study demonstrated a rearrangement of the gamma T-cell receptor gene. To our knowledge, this case is unique in terms of a posttransplant T-cell lymphoma that shows focal CD30, cytolytic granule-associated proteins, and EBV positivity. PMID:12692428

Extranodal lymphomas (ENLs) comprise about a third of all non-Hodgkin lymphomas (NHL). Radiation therapy (RT) is frequently used as either primary therapy (particularly for indolent ENL), consolidation after systemic therapy, salvage treatment, or palliation. The wide range of presentations of ENL, involving any organ in the body and the spectrum of histological sub-types, poses a challenge both for routine clinical care and for the conduct of prospective and retrospective studies. This has led to uncertainty and lack of consistency in RT approaches between centers and clinicians. Thus far there is a lack of guidelines for the use of RT in the management of ENL. This report presents an effort by the International Lymphoma Radiation Oncology Group (ILROG) to harmonize and standardize the principles of treatment of ENL, and to address the technical challenges of simulation, volume definition and treatment planning for the most frequently involved organs. Specifically, detailed recommendations for RT volumes are provided. We have applied the same modern principles of involved site radiation therapy as previously developed and published as guidelines for Hodgkin lymphoma and nodal NHL. We have adopted RT volume definitions based on the International Commission on Radiation Units and Measurements (ICRU), as has been widely adopted by the field of radiation oncology for solid tumors. Organ-specific recommendations take into account histological subtype, anatomy, the treatment intent, and other treatment modalities that may be have been used before RT.

The aim of this study was to evaluate the effectiveness of computed tomography (CT) attenuation values in the characterization of pericardial effusion. This study consisted of 96 patients with pericardial effusion who underwent pericardiocentesis. For further diagnostic evaluation of pericardial effusion, all the patients were assessed by thorax CT. CT attenuation values were measured from at least 5 different areas of pericardial fluid by specifying the largest region of interest. The average of these measurements was computed and considered as the CT attenuation value of the patient. The patients were classified into two groups: patients with transudative pericardial effusion and those with exudative pericardial effusion. CT attenuation values were significantly higher in patients with exudative pericardial effusion than in those with transudative pericardial effusion [14.85±10.7 Hounsfield unit (HU) vs. 1.13±4.3 HU, peffusion. In addition, a cut-off value of 6.5 HU had 71.4% sensitivity and 72.3% specificity for the prediction of cardiac tamponade. In patients with pericardial effusion, CT attenuation values seem to be correlated with the characterization parameters of the fluid and may distinguish exudative pericardial effusion from transudative pericardial effusion. This parameter was also found to be a predictor of cardiac tamponade. CT attenuation values can be a useful tool in the clinical evaluation of patients with pericardial effusion.

2004-01-01

Objective: To evaluate the role of high-resolution computed tomography (HRCT) in patients with leukemia and pulmonary symptoms, to establish the main patterns and to correlate them with the etiology. Materials and Methods: This is a retrospective study of the HRCT of 15 patients with leukemia and pulmonary symptoms. The examinations were performed using a spatial high-resolution protocol and were analyzed by two independent radiologists. Results: The main HRCT patterns found were ground-glass opacity (n=11), consolidation (n=9), airspace nodules (n=3), septal thickening (n=3), tree-in-bud pattern (n=3), and pleural effusion (n=3). Pulmonary infection was the most common finding seen in 12 patients: bacterial pneumonia (n=6), fungal infection (n = 4), pulmonary tuberculosis (n=1) and viral infection (n=1). Leukemic pleural infiltration (n=1), lymphoma (n=1) and pulmonary hemorrhage (n=1) were detected in the other three patients. Conclusion: HRCT is an important tool that may suggest the cause of lung involvement, its extension and in some cases to guide invasive procedures in patients with leukemia. (author)

Malignant lymphomas are differentiated into Hodgkin's and non-Hodgkin's-lymphoma (NHL). The following article discusses the imaging of extranodal NHL in supradiaphragmatic localizations. Lymphoma can affect nearly all tissues, and represent a rare entity as primary extranodal NHL. A secondary involvement of non-nodal tissue as consequence of a generalized lymphoproliferative disease is more common,and may be seen as well in HIV-positive patients defining AIDS. As extranodal lymphoma mimick the radiologic appearance of other malignant tumors, direct diagnosis without histologic analysis is often impossible. The article describes typical manifestations of lymphoma of the lungs, the head and neck area including the large glands, and rare localizations as the heart or the breast. (orig.) [de

Familial Mediterranean Fever (FMF) is a condition characterized by recurrent febrile poly-serositis. Typical presentations of the disease include episodes of fever, abdominal pain and joint pains. Chest pain is a less common presentation. We report a case of FMF which presented with a large pericardial effusion and bilateral pleural effusions in a lady who had no positive family history and negative genetic testing.

Simultaneous presence of ascites and pleural effusion has been documented in patients with cirrhosis of the liver, renal disease, Meigs' syndrome and in patients undergoing peritoneal dialysis. Mechanisms proposed in the formation of pleural effusion in most of the above diseases are lymphatic drainage and diaphragmatic defect. But sometimes, hepatic hydrothoraxes in the absence of clinical ascites and pleural effusion secondary to pulmonary or cardiac disease are noted. It is not always possible to differentiate between pleural effusion caused by transdiaphragmatic migration of ascites and by other causes based solely on biochemical analysis. Authors performed radionuclide scintigraphy after intraperitoneal administration of 99m Tc-labeled colloid in 23 patients with both ascites and pleural effusion in order to discriminate causative mechanisms responsible for pleural effusion. Scintigraphy demonstrated the transdiaphtagmatic flow of fluid from the peritoneum to pleural cavities in 13 patients correctly. In contrast, in 5 patients with pleural effusion secondary to pulmonary, pleural and cardiac diseases, radiotracers fail to traverse the diaphragm and localize in the pleural space. Ascites draining to mediastinal lymph nodes and blocked passage of lymphatic drainage were also clarified, additionally. Conclusively, radionuclide peritoneal scintigraphy is an accurate, rapid and easy diagnostic tool in patients with both ascites and pleural effusion. It enables the causes of pleural effusion to be elucidated, as well as providing valuable information required when determining the appropriate therapy.

Objective. To investigate the relationship among angiogenic cytokines, inflammatory markers, and fibrinolytic activity in tuberculous pleural effusion (TBPE) and their clinical importance. Methods. Forty-two patients diagnosed with TBPE were studied. Based on chest ultrasonography, there were 26 loculated and 16 nonloculated TBPE patients. The effusion size radiological scores and effusion vascular endothelial growth factor (VEGF), interleukin- (IL-) 8, plasminogen activator inhibitor type-1 (PAI-1), and tissue type plasminogen activator (tPA) were measured. Treatment outcome and pleural fibrosis, defined as radiological residual pleural thickening (RPT), were assessed at 6-month follow-up. Results. The effusion size and effusion lactate dehydrogenase (LDH), VEGF, IL-8, PAI-1, and PAI-1/tPA ratio were significantly higher, while effusion glucose, pH value, and tPA were significantly lower, in loculated than in nonloculated TBPE. VEGF and IL-8 correlated positively with LDH and PAI-1/tPA ratio and negatively with tPA in both loculated and nonloculated TBPE. Patients with higher VEGF or greater effusion size were prone to develop RPT (n = 14; VEGF, odds ratio 1.28, P = 0.01; effusion size, odds ratio 1.01, P = 0.02), and VEGF was an independent predictor of RPT in TBPE (receiver operating characteristic curve AUC = 0.985, P Effusion VEGF correlates with pleural inflammation and fibrosis and may be targeted for adjunct therapy for TBPE.

Pericardial effusions following radiotherapy for Hodgkins Disease have previously been described as infrequent and related to the total dose of radiation received. Analysis of all chest x-rays on 81 patients who received upper-mantle radiotherapy for Hodgkins Disease at the Baltimore Cancer Research Center between 1968 and 1972 disclosed an incidence of pericardial effusions of 30.9% (25 of 81), with 13.6% (11 of 81) requiring limitation of activity (5) or pericardiectomy (6). Clinical presentation of radiation-related pericardial effusions was subtle, with signs and symptoms a late finding if they occurred. Radiotherapy data was reviewed and no difference in total dose (rads) or time-dose relationships (rets) was found between the groups who did or did not develop effusions. Analysis of multiple pre-treatment clinical and pathological characteristics disclosed four parameters that were felt to be related to the development of pericardial effusions; elevated ESR, normal absolute lymphocyte count, initial presence of extensive mediastinal adenopathy and the addition of adjuvant chemotherapy. The presence of increasing combinations of these pretreatment 'risk factors' led to an increasing likelihood of developing a radiation-related pericardial effusion such that six of seven patients with all four 'risk factors' developed a pericardial effusion. Nine of 13 clinically significanteffusions were associated with the addition of adjuvant chemotherapy. Possible pathogenetic mechanisms that include factors other than radiation dosage and the clinical management of radiation-related pericardial effusions are discussed

Full text: Introduction: A pleural effusion is defined as an abnormal amount of fluid in the space between the layers of tissue (the pleura) that line the lungs. If cancer cells are present in this fluid (pleural cavity) it is called a malignant cancerous pleural effusion. Many benign and malignant disease can cause pleural effusion.The new onset of pleural effusion may herald the presence of a previously undiagnosed malignancy, or more typically, complicate the course of a known lung tumor. Malignant pleural effusions can lead lead to an initial diagnosis of lung cancer in patients.and it was the first symptom of lung cancer. Pleural deposits of tumor cause pleuritic pain. Purpose of this presentation is to show the role of CT in diagnosis of malignant pleural effusion and lung cancer. Material and methods: CT examinations of chest were made to 138 patients for 1 year (1/6/2011- 1/6/2012) with Siemens Somatom Emotion 16 CT Scanner. Patients were at age of 30 -81 years, 93 of them are male and 45 are female. Results: 56 (40.5%) of the patients had pleural effusion. From this group 21 37.5% had malignant pleural effusion and lung cancer. 17 (81%) of them are male, and 4 (19%) are female. 9 (43%) diagnosed lung cancer for first time. Conclusion: Pleural effusion more commonly occur in patient with advanced-stage tumor who frequently have metastases to other organs and long-term survival is uncommon in this group. CT diagnosed malignant pleural effusion and lung cancer and help to choice treatment for these patients

Lymphoepithelioid cell lymphoma (Lennert's lymphoma) is a rare morphological variant of peripheral T-cell lymphoma characterized by the presence of numerous clusters of epithelioid histiocytes without formation of discrete granulomas and the intervening atypical lymphocytes. Lennert's lymphoma is often misinterpreted as granulomatous lymphadenitis or Hodgkin's disease. This report describes fine needle aspiration cytology and histological findings in a case of Lennert's lymphoma. (author)

The most efficient and cost-effective approach for the diagnosis of pleural exudates remains uncertain and is a subject of controversy. Essential factors to be considered include the respective diagnostic yields of thoracocentesis, closed pleural biopsy, and thoracoscopy. The role of endoscopic ultrasound (EUS) of the esophagus as a modality for the evaluation of pleural exudates has not yet been evaluated. The applied anatomy of the pleura has been discussed. The techniques involved in the EUS imaging of different aspects of the pleura in normal cases and in cases with pleural effusion are elaborated. The practical application of this knowledge can be useful in EUS-guided sampling of the pleural wall, pleural nodules, and in cases of pleural effusion.

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

Science.gov (United States)

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.

Allergic bronchopulmonary aspergillosis: a rare cause of pleural effusion.

Aspergillus fumigatus is one of the most ubiquitous of the airborne saprophytic fungi. Allergic bronchopulmonary aspergillosis (ABPA) is a syndrome seen in patients with asthma and cystic fibrosis, and is characterized by hypersensitivity to chronic colonization of the airways with A. fumigatus. We report the case of a patient with ABPA presenting with pleural effusion. A 27-year-old male was referred with recurrent right pleural effusion. Past medical history was remarkable for asthma, allergic sinusitis, and recurrent pleurisy. Investigations revealed peripheral eosinophilia with elevated serum immunoglobulin E and bilateral pleural effusions with bilateral upper lobe proximal bronchiectasis. Precipitating serum antibodies to A. fumigatus were positive and the A. fumigatus immediate skin test yielded a positive reaction. A diagnosis of ABPA associated with bilateral pleural effusions was made and the patient was commenced on prednisolone. At review, the patient\\'s symptoms had considerably improved and his pleural effusions had resolved. ABPA may present with diverse atypical syndromes, including paratracheal and hilar adenopathy, obstructive lung collapse, pneumothorax and bronchopleural fistula, and allergic sinusitis. Allergic bronchopulmonary aspergillosis is a rare cause of pleural effusion and must be considered in the differential diagnosis of patients presenting with a pleural effusion, in particular those with a history of asthma.

The lymphomas of the mucosal-associated lymphatic tissue (MALT represent only 0.2-0.3% and constitute a well-defined group of non-Hodgkin lymphomas of B origin. In the field of oral pathology, the salivary glands, tonsils and palate are mainly affected, it is more rare to find it in jugal mucosa.We present a rare case of MALT lymphoma with involvement of the palate and orbit. MATERIAL AND METHODS84-year-old patient with multiple pathologies. Derived from his primary care physician due to pharyngeal complaints of 4 to 5 days of evolution, associated with a painful palate lesion.He presented in right hemipaladar a tumoration of elastic consistency in submucosa, ulcerated in the center, with normal neck. Also left orbital tumor that limits the visual field. RESULTSCT and MRI of the neck report mass of 4x4 x2.5 cm in right hemipaladar, noninfiltrating concordant with possible lymphoma. The orbital MRI describes an intra and extra nasal left nasal lesion of 2.3x1.2x2 cm with characteristics consistent with lymphoma. CT of the neck: It demostrates a great mass of right hemipaladar, with lobulated contours and homogeneous enhancement of 40x32x25 mm, in intimate contact with medial pterygoid muscle, although there were no signs of infiltration, the rest of the edges being well delimited. Images characteristics look like a lymphoma, without being able to rule out other etiologies. MRI of the neck: It demostrates a diffuse thickening of right side of the soft palate that

We investigated the results of radiotherapy for mucosa-associated lymphoid tissue (MALT) lymphoma of the ocular adnexa. Twenty-one patients with MALT lymphoma of the ocular adnexa were treated with radiotherapy alone at a dose ranging from 30 to 54 Gy. The disease arose from the conjunctiva in 15 patients (9 with bilateral involvement), and from the retrobulbar space in 6 patients (1 with bilateral involvement). All patients with MALT lymphoma achieved a complete response (CR) or unconfirmed CR (CRu). The 5- and 10-year overall survival rates of all patients with MALT lymphoma were 100% and 90%, respectively. The 5- and 10-year cause-specific survival rates were 100% and 100%, respectively. In all patients with delayed toxicity, the radiation dose was more than 40 Gy. Excellent local control and survival can be achieved for patients with MALT lymphoma of the ocular adnexa using radiotherapy alone. (author)

2015-09-01

Full Text Available We present a case of a 65-year-old Hispanic man with a history of disseminated cutaneous coccidioidomycosis who presented to the emergency room for progressively worsening abdominal pain associated with shortness of breath. The patient was found to have pleural effusion and moderate ascites on physical examination. Abdominal ultrasound and computed tomography scan were consistent with moderate ascites and portal hypertension but negative for both liver cirrhosis and for venous or arterial thrombosis. Cytology of ascitic fluid was suggestive of portal hypertension and was negative for infection. Subsequent, thoracentesis was suggestive of exudative effusion and also negative for infection. Liver biopsy confirmed the absence of cirrhosis. Complete blood count indicated pancytopenia, whereas bone marrow biopsy and flow cytometry were suggestive of marginal zone lymphoma (MZL. Clinically, the patient’s shortness of breath was resolved by thoracentesis and paracentesis; however, his abdominal pain persisted. A diagnosis of idiopathic noncirrhotic portal hypertension in the setting of splenic MZL was made. The patient was transferred to a higher level of care for splenectomy; however, he missed multiple appointments. Since discharge, the patient has been seen in the outpatient setting and states that he is controlling his disease with diet and exercise; however, he continues to complain of intermittent shortness of breath with exertion.

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.

This study was designed to evaluate the safety and efficacy of CT-guided drainage of the pericardial effusion in patients after cardiac surgery. The study included 128 consecutive patients (82 males, 46 females; mean age 66.6 years, SD: 4.2) complicated by pericardial effusion or hemopericardium after cardiac surgeries between June 2008 and June 2016. The medical indication for therapeutic pericardiocentesis in all patients was hemodynamic instability caused by pericardial effusion. The treatment criteria for intervention were evidence of pericardial tamponade with ejection fraction (EF) effusion was 260 ml (range 80-900 ml; standard deviation [SD]: ±70).

Untargeted mass spectrometry-based metabolomic profiling is a powerful analytical method used for broad-spectrum identification and quantification of metabolites in biofluids in human health and disease states. In this study, we exploit metabolomic profiling for cancer biomarker discovery for diagnosis of malignant pleural effusions. We envisage the result will be clinically useful since currently there are no cancer biomarkers that are accurate enough for the diagnosis of malignant pleural effusions. Metabolomes of 32 malignant pleural effusions from lung cancer patients and 18 benign effusions from patients with pulmonary tuberculosis were analyzed using reversed-phase liquid chromatography tandem mass spectrometry (LC-MS/MS) using AB SCIEX TripleTOF 5600. MS spectra were analyzed using XCMS, PeakView, and LipidView. Metabolome-Wide Association Study (MWAS) was performed by Receiver Operating Characteristic Curve Explorer and Tester (ROCCET). Insignificant markers were filtered out using a metabolome-wide significance level (MWSL) with p-value pleural effusions. Using a ratio of FFA 18:1-to-ceramide (d18:1/16:0), the area-under-ROC was further increased to 0.99 (95% CI = 0.91-1.00) with sensitivity 93.8% and specificity 100.0%. Using untargeted metabolomic profiling, the diagnostic cancer biomarker with the largest area-under-ROC can be determined objectively. This lipogenic phenotype could be explained by overexpression of fatty acid synthase (FASN) in cancer cells. The diagnostic performance of FFA 18:1-to-ceramide (d18:1/16:0) ratio supports its use for diagnosis of malignant pleural effusions.

The case is presented of a 43 year-old male patient with chronic follicular conjunctivitis, negative bacterial serology, and refractory to local treatment. The incisional biopsy performed showed to be consistent with reactive lymphoid hyperplasia. A year later, a new incisional biopsy showed follicular lymphoma, with no systemic involvement, and he was treated with local radiotherapy. When a chronic follicular conjunctivitis is refractory to treatment, it is essential to perform an incisional biopsy to establish the histopathological diagnosis that can range from chronic inflammation, reactive lymphoid hyperplasia to lymphoma. Follicular lymphoma is rare among conjunctival lymphomas, and the staging is indispensable for the correct therapeutic approach. Copyright © 2014 Sociedad Española de Oftalmología.

The purpose of this study is to determine whether MR images after intravenous administration of Gd-DTPA can differentiate exudative and transudative pleural effusion. We studied 18 patients with ten exudative and eight transudative pleural effusions diagnosed clinically and by thoracentesis. We analysed the relationship between T1 value(normalized to fat) and the ratio of effusion/serum protein of pleural effusion. We also assessed the contrast enhancement of exudative and transudative pleural effusion on T1 weighted SE images taken at 15 and 30minutes after administration of Gd-DTPA. The relationship between the effusion/serum protein ratio and T1 value(normalized to fat) was statistically not significant(r=0.27, P=0.381). On precontrast spin-echo T1WI, mean signal intensity of the transudate was 0.18(±0.04) and that of the exudate was 0.24(±0.07), values which were not significant differences(P>0.05). Postcontrast mean signal intensities of transudates at 15 and 30 were 0.20±0.06 and 0.26±0.08, respectively, values which were not significantly higher than that of precontrast mean signal intensity(P<0.05). Postcontrast mean signal intensity values of exudative pleural effusions at 15 and 30 minutes(0.32±0.06 and 0.39±0.06, respectively) were, on the other hand, significantly higher than that of precontrast mean signal intensity(P<0.05). Postcontrast T1-weighted SE images at 15 and 30 minutes can be helpful in the differentiation of transudative and exudative pleural effusion

MR examinations of 36 patients with pleural and/or pericardial effusions were retrospectively evaluated. The purpose of this study was to determine of MR imaging is capable of differentiating between pleural and pericardial effusions of different compositions using standard electrocardiogram (ECG)-gated and nongated spin echo pulse sequences. Additional data was obtained from experimental pleural effusions in 10 dogs. The results of this study indicate that old haemorhages into the pleural or pericardial space can be differentiated from other pleural or pericardial effusions. However, further differentiation between transudates, exudates and sanguinous effusions is not possible on MR images acquired with standard spin echo pulse sequences. (orig./MG)

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.

Amyloidosis diagnosed in cytology specimen of pleural effusion: A case report.

Science.gov (United States)

Manur, Rashmi; Lamzabi, Ihab

2018-06-01

Amyloidosis is a rare condition resulting from extracellular deposition of amyloid, a fibrillary material derived from various precursor proteins. Involvement of the pleura by amyloidosis is a rare but serious complication. Pleural amyloidosis is primarily diagnosed by identifying amyloid deposition by histology on pleural biopsy specimens. Hereby, we report a case of systemic amyloidosis where we were able to identify amyloid in a pleural effusion specimen sent for cytopathology evaluation. A 59-year-old male with newly diagnosed multiple myeloma and systemic amyloidosis underwent therapeutic thoracentesis. The H&E stained cell block sections revealed a single, less than one millimeter focus of waxy material surrounded by a rim of reactive mesothelial cells suspicious for amyloid deposit in a background of fibrin, lymphocytes, and reactive mesothelial cells. The focus stained salmon pink with Congo-red special stain and showed apple-green birefringence under polarized light. Our finding suggests that pleural involvement in patients with systemic amyloidosis can be identified on effusion specimens and avert the need for more invasive procedures like pleural or pulmonary parenchymal biopsies. © 2017 Wiley Periodicals, Inc.

The two diseases may present clinically as concurrent or sequential disease (10. Herein we are reporting a Pakistani female in her 60s, a carrier of hepatitis B virus with multiple comorbidities presented with cervical lymphadenopathy, diagnosed as Hodgkin's lymphoma, mixed cellularity. During the staging workup, the patient was discovered to have extensive bone marrow (BM involvement by Burkitt leukaemia/lymphoma (BL. Cytogenetic analysis revealed positivity for t(8;14(q24;q32 confirmed by Fluorescence In Situ Hybridization (FISH for IGH/MYC. Epstein-Barr virus (EBV was demonstrated heavily in our case, with (EBV DNA of 24,295,560 copies/ml by PCR at time of presentation, in addition, the neoplastic cells in both diagnostic tissues (cervical lymph node and BM demonstrated positivity for EBV. A diagnosis of concomitant EBV related discordant lymphoma (classical Hodgkin lymphoma (cHL and Burkitt lymphoma (BL in leukemic phase was made. Among all reported cases, this case is highly exceptional because it is the first case of discordant/composite lymphoma, with this combination and concomitant presentation. Since we are dealing with a case with an exceptionally rare combination, we found it significant to elaborate more on its clinical features, contributing factors including EBV role, response to treatment, complications, and prognosis.

Full Text Available Introduction: Pathological involvement of pericardium by any disease that resulting in effusion may require decompression and pericardiectomy. The current article describes rare patients with effusion who after pericadiectomy and transient hemodynamic improvement rapidly developed progressive heart failure and subsequent multi organ failure.Methods: During periods of five years, 423 patients in our hospital underwent pericardiotomy for decompression of effusion. The clinical characteristics of those patient with postoperative low cardiac output (B group (14 cases recorded and compared with other patients without this postoperative complication (A group by test and X2. Significant variables in invariables (P≤0.1 entered in logistic regression analysis and odd ratio of these significant variables obtained. Results: Idiopathic pericardial effusion, malignancy, renal failure, connective tissue disease, viral pericarditis was found in 125 patients (27%, 105 patients (25.4%, 65 patients (15.6%, 50 (17.1% and 10 (2.4% of patients subsequently. The factors that predict post-operative death in logistic regression analysis were malignancy, radiotherapy, constrictive pericarditis inotropic drug using IABP using, pre-operative EF and pericardial calcification.Conclusion: Certain preoperative variables such as malignancy, radiotherapy, low EF, calcified pericardium and connective tissue disease are associated with POLCOS and post-operative risk of death. This paradoxical response to pericardial decompression may be more frequent than currently appreciated. Its cause may relate to the sudden removal of the chronic external ventricular support from the effusion or thicken pericardium resulting in ventricular dilatation and failure or intra operative myocardial injury due to pericardiectomy of calcified pericardium, radiation and cardiomyopathy.

To evaluate the outcome and safety of ultrasound-guided percutaneous catheter drainage of exudative pleural effusion. The present study was a retrospective analysis of 412 pleural effusions from 373 patients that underwent ultrasound-guided small-bore catheter drainage in exudative pleural effusions between 2004 and 2009. The two most common causes for drainage were parapneumonic effusion or empyema (52.2%) and malignant effusion (30.3%), while the remains were trauma, iatrogenic, and others. Overall clinical success rate was 76.5%. The success rate was lower among malignant pleural effusion (p = 0.003). Causes of effusion were the only independent predictors related to success. Only five (1.2%) patients developed complication during the procedure. Seventy-five of 412 effusions (15.8%) developed complication during the period of drainage; the majority were drain blockage (9%) and accidental dislodgment (4.1%). Ultrasound-guided small-bore catheter drainage was a safe and efficient procedure for exudative pleural effusions.

The cause of exudative pleural effusion cannot be determined in some patients. The longterm outcomes of patients with undiagnosed pleural effusion were analyzed. Patients with exudative pleural effusion whose diagnostic procedures included pleural biopsy using video-assisted thoracoscopic surgery carried out between 2008 and 2012 were evaluated retrospectively. Patients diagnosed with non-specific pleuritis were included. Fifty-three patients with available follow-up data were included in the study. Forty men and 13 women (mean age 53.9±13.9 years) were included. Median follow-up time was 24 months. No diagnosis was given in 27 patients (51%), and a clinical diagnosis was given in 26 patients (49%) during the follow-up period. Malignant disease (malignant mesothelioma) was diagnosed in 2 (3.7%) patients. Other diseases were parapneumonic effusion in 12, congestive heart failure in 8, and miscellaneous in 4 patients. Volume of effusion at the time of initial examination and re-accumulation of fluid after video-assisted thoracoscopic surgery were associated with malignant disease (P=.004 and .0001, respectively). Although the probability is low, some patients with exudative pleural effusion undiagnosed after pleural biopsy via video-assisted thoracoscopic surgery may have malignant disease. Patients with an initially large volume of effusion that re-accumulates after examination should be closely monitored. Copyright © 2014 SEPAR. Published by Elsevier Espana. All rights reserved.

Concomitant occurrence of sinus histiocytosis with massive lymphadenopathy and nodal marginal zone lymphoma.

Pang, Changlee S; Grier, David D; Beaty, Michael W

2011-03-01

Sinus histiocytosis with massive lymphadenopathy (SHML), also known as Rosai-Dorfman disease, is a rare self-limiting disorder of histiocytes with unknown etiology. Sinus histiocytosis with massive lymphadenopathy is most common in children and young adults and is characterized by painless lymphadenopathy. Histologically there is a proliferation of sinus histiocytes with lymphophagocytosis or emperipolesis. On rare occasions, SHML has been associated with lymphoma, usually involving different anatomic sites and developing at different times. We report a case of concomitant SHML and nodal marginal zone lymphoma involving the same lymph node without involvement of other nodal or extranodal sites. The presence of concomitant SHML within the lymph node involved by nodal marginal zone lymphoma may represent the responsiveness of SHML histiocytes to B-cell-derived cytokines in lymphoproliferative disorders. To our knowledge, this is the first description of concomitant occurrence of SHML and nodal marginal zone lymphoma.

Although pulmonary artery banding (PAB) is a common palliative procedure for pediatric heart malformation, there are concerns of pressure overload and concomitant immune reactions in the right ventricle causing postsurgical complications such as pericardial effusion. At this time, no clear guidelines as to potential risk factors or procedural contraindications have been widely disseminated. Therefore, a study was undertaken to examine wide-ranging factors to find potential biomarkers for postsurgical pericardial effusion formation risk. A retrospective study was conducted on all cardiac surgeries performed over an eight-year period, and the main inclusion criterion was pericardial effusion development after PAB that required surgical drainage. Nine cases were then analyzed against a control group of 45 cases with respect to body measurements, concomitant surgeries, genetic screens, laboratory tests results, and cardiac function parameters. Trisomy 21 was strongly associated with the development of severe pericardial effusion after PAB, and postoperative serum albumin levels in patients with trisomy 21 were associated with pericardial effusion development. Other parameters showed no significant correlation with pericardial effusion development. Our data indicate a strong association between trisomy 21 and pericardial effusion requiring drainage after PAB, which is in line with translational research findings. Pressure overload from PAB may play a role in the formation of severe pericardial effusion that is exacerbated by cardiac structural defects commonly associated with trisomy 21. Surgical teams should therefore use caution and plan to implement drainage in PAB cases, and postoperative serum albumin may serve as a useful biomarker for pericardial effusion formation.

The aim of this study was to establish how reliable a given tympanogram is in predicting the presence or absence of a middle ear effusion, and to provide new views for the diagnostic information of tympanometry. The use of tympanometric gradient in addition to static admittance is the focus of this study. The authors enrolled 146 female and 129 male patients. The participants were allocated into groups as follow: Group A1 consisted of 50 healthy children. Group A2 consisted of 86 children with otitis media with effusion. Group B1 consisted of 85 healthy adults. Group B2 consisted of 54 adults with otitis media with effusion. All diagnostic otoscopic examination and tympanometry were performed in both ears. The authors analyzed the distribution of tympanograms in patients with otitis media with effusion and healthy controls. When the right and left ear canal volume of either children or adults with otitis media with effusion compared with healthy controls, no statistically significant different was observed (P > 0.05). On the other hand, the statistically significant difference was detected for the values of compliance, pressure and gradient of either children or adults with otitis media with effusion compared with healthy controls (P effusion. The authors think that tympanometric gradient may be useful to detect the otitis media with effusion.

To investigate the relationship among angiogenic cytokines, inflammatory markers, and fibrinolytic activity in tuberculous pleural effusion (TBPE) and their clinical importance. Forty-two patients diagnosed with TBPE were studied. Based on chest ultrasonography, there were 26 loculated and 16 nonloculated TBPE patients. The effusion size radiological scores and effusion vascular endothelial growth factor (VEGF), interleukin- (IL-) 8, plasminogen activator inhibitor type-1 (PAI-1), and tissue type plasminogen activator (tPA) were measured. Treatment outcome and pleural fibrosis, defined as radiological residual pleural thickening (RPT), were assessed at 6-month follow-up. The effusion size and effusion lactate dehydrogenase (LDH), VEGF, IL-8, PAI-1, and PAI-1/tPA ratio were significantly higher, while effusion glucose, pH value, and tPA were significantly lower, in loculated than in nonloculated TBPE. VEGF and IL-8 correlated positively with LDH and PAI-1/tPA ratio and negatively with tPA in both loculated and nonloculated TBPE. Patients with higher VEGF or greater effusion size were prone to develop RPT (n=14; VEGF, odds ratio 1.28, P=0.01; effusion size, odds ratio 1.01, P=0.02), and VEGF was an independent predictor of RPT in TBPE (receiver operating characteristic curve AUC=0.985, PEffusion VEGF correlates with pleural inflammation and fibrosis and may be targeted for adjunct therapy for TBPE.

The aim of this study is to identify the factors associated with the occurrence of pleural effusion and to investigate the characteristics of pleural effusion in scrub typhus. We conducted a retrospective analysis of the medical records of scrub typhus patients between January 2004 and December 2011 at Chosun University Hospital in South Korea. A total of 445 scrub typhus patients were divided into the following two groups: without (n = 352) or with pleural effusion (n = 93). The data of 18 scrub typhus patients who underwent thoracentesis were summarized. Multivariate analysis demonstrated that the following factors were associated with the occurrence of pleural effusion in scrub typhus: older age (odds ratio [OR] = 1.029, P = 0.037, confidence interval [CI] = 1.002-1.056); male gender (OR = 1.924, P = 0.020, CI = 1.109-3.340); presence of heart failure (OR = 2.628, P = 0.039, CI = 1.052-6.565); and lower albumin (OR = 0.107, P ≤ 0.001, CI = 0.058-0.196). Most pleural effusion presentations were bilateral (88 %) and small (91 %). The effusion had transudate characteristics in 7 patients and exudate characteristics in 11 patients based on Light's criteria. This study provided the first data regarding the following four independent risk factors associated with the occurrence of pleural effusion: older age; male gender; the presence of heart failure; and lower albumin. The pleural effusion presentations in scrub typhus patients were bilateral and small in most cases, with transudate and/or exudate characteristics.

Malignant pleural effusion is a common complication of primary and metastatic pleural malignancies. Pleurodesis for the management of malignant pleural effusion is intended to achieve symphysis between parietal and visceral pleura, and to prevent relapse of pleural effusion. Many chemical agents are tried to induce inflammation and damage of the pleural mesothelial layer to achieve this symphysis. Hemorrhagic pleural effusion, especially in the right hemithorax commonly occurs as presentation of primary and metastatic pleural malignancies. This case reports massive right-sided hemorrhagic pleural effusion as the sole manifestation of primary lung cancer in a 45 year old man. Patient attended our department of thoracic surgery complaining of cough, shortness of breath and right sided chest pain. A chest X-ray and chest computer tomography (CT) radiograph shows right sided massive pleural effusion. Right sided tube thoracotomy done. Pleural fluid study was done. Fluid for cytopathology was positive for malignant cell. Computed tomography guided fine needle aspiration cytology from right lung lesion was also done. Diagnosis was as small cell carcinoma. Pleural effusion resolved after 9(th) post operative day of chest tube insertion. Bleomycin pleurodesis was done. Day after pleurodesis intra thoracic tube was removed and patient was discharged from hospital on 10(th) Post operative day with an advice to attend the oncology department for further treatment. The protocol of tube thoracostomy and chemical pleurodesis was almost always successful in giving symptomatic relief of respiratory distress for a considerable period of time. However, chemical pleurodesis is not possible in all cases of malignant pleural effusion because it has got potential complication including death.

Diffuse large cell B-cell lymphoma of the skin is most commonly represented by diffuse large cell variants of primary cutaneous follicle center cell lymphoma and the leg-type lymphoma. In a minority of cases, the infiltrates are an expression of stage 4 disease of established extracutaneous B-cell lymphoma. We describe 3 patients with an aggressive form of B-cell lymphoma secondarily involving the skin. Two of the patients were in the ninth decade of life, whereas 1 patient was 34 years of age. In the elderly patients, there was an antecedent and/or concurrent history of follicular lymphoma, whereas in the younger patient, the tumor was a de novo presentation of this aggressive form of lymphoma. The elderly patients succumbed to their disease within less than a year from the time of diagnosis, whereas 1 patient is alive but with persistent and progressive disease despite chemotherapeutic intervention. The infiltrates in all 3 cases were diffuse and composed of large malignant hematopoietic cells that exhibited a round nucleus with a finely dispersed chromatin. Phenotypically, the tumor cells were Bcl-2 and CD10 positive, whereas Bcl-6 and Mum-1 showed variable positivity. One case showed combined Mum-1 positivity along with an acute lymphoblastic lymphoma phenotype, including the absence of CD20 expression. In each case, there was a c-MYC and BCL2/IGH rearrangement diagnostic of double-hit lymphoma. In one case, there was an additional BCL6 rearrangement, defining what is in essence triple-hit lymphoma. In conclusion, double-hit lymphoma is an aggressive form of B-cell neoplasia resistant to standard chemotherapy regimens, which in many but not all cases represents tumor progression in the setting of a lower grade B-cell malignancy.

Neoplasm is an uncommon cause of a parkinsonian syndrome. We report a woman with primary brain B-cell lymphoma presenting as Parkinson's disease. After 1 year of the illness, CT and MRI showed lesions without mass effect in the basal ganglia and corpus callosum. The patient did not respond to levodopa and right cerebellar and brain-stem signs appeared, which prompted further neuroimaging, showing an increase in size of the lesions and a right cerebellar and pontine mass. Stereotactic biopsy of the basal ganglia showed high-grade B-cell lymphoma. Despite the basal ganglia frequently being involved in lymphoma of the brain, presentation with typical or atypical parkinsonism is exceptional. (orig.)

Full Text Available Tolosa-Hunt syndrome (THS is a painful condition characterized by hemicranial pain, retroorbital pain, loss of vision, oculomotor nerve paralysis, and sensory loss in distribution of ophthalmic and maxillary division of trigeminal nerve. Lymphomas rarely involve cavernous sinus and simulate Tolosa-Hunt syndrome. Here we present a first case of double-hit B cell lymphoma (DHL relapsing and masquerading as Tolosa-Hunt syndrome. The neurological findings were explained by a lymphomatous infiltration of the right Gasserian ganglion which preceded systemic relapse. As part of this report, the diagnostic criteria for Tolosa-Hunt syndrome and double-hit lymphoma are reviewed and updated treatment recommendations are presented.

Full Text Available The gastrointestinal tract (GIT is the most commonly involved site of extranodal lymphomas. The close association between chronic inflammation and specific GIT lymphomas not only provide interesting insights into the pathobiology of lymphomas but also poses unique diagnostic challenges. A clear understanding of marginal zone and mucosa associated lymphoid tissue (MALT in health and disease is helpful to place GIT lymphomas in proper context. A wide variety of lymphomas besides MALT lymphomas occur in various parts of the GIT. The characteristic pathological, immunophenotypic, and genetic features of different GIT lymphomas categorized according to World Health Organization (WHO classification are presented. The epidemiological, clinical, and pathological features of lymphomas occurring in each part of the GIT are summarized and the key points regarding lymphomas at each site are emphasized. A tabular summary of the important differential diagnostic considerations at each site is given and suggestions for a minimal diagnostic work up are provided.

Purpose: To investigate clinical and pathologic factors significant in predicting local response and time to further treatment after low-dose involved-field radiation therapy (LD-IFRT) for non-Hodgkin lymphoma (NHL). Methods and Materials: Records of NHL patients treated at a single institution between April 2004 and September 2011 were retrospectively reviewed. Low-dose involved-field radiation therapy was given as 4 Gy in 2 fractions over 2 consecutive days. Treatment response and disease control were determined by radiographic studies and/or physical examination. A generalized estimating equation model was used to assess the effect of tumor and patient characteristics on disease response. A Cox proportional hazards regression model was used to assess time to further treatment. Results: We treated a total of 187 sites in 127 patients with LD-IFRT. Histologies included 66% follicular, 9% chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma, 10% marginal zone, 6% mantle cell lymphoma (MCL), and 8% other. Median follow-up time was 23.4 months (range, 0.03-92.2 months). The complete response, partial response, and overall response rates were 57%, 25%, and 82%, respectively. A CLL histology was associated with a lower response rate (odds ratio 0.2, 95% confidence interval 0.1-0.5, P=.02). Tumor size, site, age at diagnosis, and prior systemic therapy were not associated with response. The median time to first recurrence was 13.6 months. Those with CLL and age ≤50 years at diagnosis had a shorter time to further treatment for local failures (hazard ratio [HR] 3.63, P=.01 and HR 5.50, P=.02, respectively). Those with CLL and MCL had a shorter time to further treatment for distant failures (HR 11.1 and 16.3, respectively, P<.0001). Conclusions: High local response rates were achieved with LD-IFRT across most histologies. Chronic lymphocytic leukemia and MCL histologies and age ≤50 years at diagnosis had a shorter time to further treatment after LD-IFRT.

Primary nodal peripheral T-cell lymphomas: diagnosis and therapeutic considerations

Full Text Available Nodal peripheral T-cell lymphomas are a rare group of neoplasms derived from post-thymic and activated T lymphocytes. A review of scientific articles listed in PubMed, Lilacs, and the Cochrane Library databases was performed using the term "peripheral T-cell lymphomas". According to the World Health Organization classification of hematopoietic tissue tumors, this group of neoplasms consists of peripheral T-cell lymphoma not otherwise specified (PTCL-NOS, angioimmunoblastic T-cell lymphoma (AITL, anaplastic large cell lymphoma-anaplastic lymphoma kinase positive (ALCL-ALK+, and a provisional entity called anaplastic large cell lymphoma-anaplastic lymphoma kinase negative (ALCL-ALK-. Because the treatment and prognoses of these neoplasms involve different principles, it is essential to distinguish each one by its clinical, immunophenotypic, genetic, and molecular features. Except for anaplastic large cell lymphoma-anaplastic lymphoma kinase positive, which has no adverse international prognostic index, the prognosis of nodal peripheral T-cell lymphomas is worse than that of aggressive B-cell lymphomas. Chemotherapy based on anthracyclines provides poor outcomes because these neoplasms frequently have multidrug-resistant phenotypes. Based on this, the current tendency is to use intensified cyclophosphamide, doxorubicin, vincristine, prednisolone (CHOP regimens with the addition of new drugs, and autologous hematopoietic stem cell transplantation. This paper describes the clinical features and diagnostic methods, and proposes a therapeutic algorithm for nodal peripheral T-cell lymphoma patients.

Epstein-Barr virus-associated lymphomas.

Epstein-Barr virus (EBV), originally discovered through its association with Burkitt lymphoma, is now aetiologically linked to a remarkably wide range of lymphoproliferative lesions and malignant lymphomas of B-, T- and NK-cell origin. Some occur as rare accidents of virus persistence in the B lymphoid system, while others arise as a result of viral entry into unnatural target cells. The early finding that EBV is a potent B-cell growth transforming agent hinted at a simple oncogenic mechanism by which this virus could promote lymphomagenesis. In reality, the pathogenesis of EBV-associated lymphomas involves a complex interplay between different patterns of viral gene expression and cellular genetic changes. Here we review recent developments in our understanding of EBV-associated lymphomagenesis in both the immunocompetent and immunocompromised host.This article is part of the themed issue 'Human oncogenic viruses'. © 2017 The Authors.

2000-01-01

We present the clinical and magnetic resonance imaging findings of a patient who, following treatment for pancreatic non-Hodgkin's lymphoma (NHL), relapsed with apparently isolated involvement of the right masticator space and left psoas muscles. Non-Hodgkin's lymphoma arising from the masticator space muscles is very rare. In addition, simultaneous lymphomatous involvement of multiple discrete skeletal muscle sites, in the absence of disease elsewhere, has previously only been reported in the limb or limb girdle muscles. Lymphoma should be considered as a cause of isolated enlarged skeletal muscles, even when involving such distant sites. (orig.)

The aim of this study was to investigate the capability of Gd-DTPA-enhanced MRI to differentiate between exudative and transudative pleural effusions. An MRI examination was performed on 22 patients with different types of pleural effusion (10 transudative and 12 exudative effusions). T1-weighted SE images were obtained before and 20 min after administration of Gd-DTPA (0.1 mmol/kg). The degree of enhancement of pleural effusions was evaluated both by visual assessement and by quantitative analysis of images. None of 10 transudative effusions showed significative enhancement, whereas 10 of 12 exudative effusions showed enhancement (sensitivity 83 %, specificity 100 %, positive predictive value 100 %). The postcontrast signal intensity ratios (SIRs) of exudates were significantly higher than corresponding precontrast ratios (P = 0.0109) and the postcontrast SIRs of exudates were significantly higher than those of transudates (P = 0.0300). Exudative pleural effusions show a significant enhancement following administration of Gd-DTPA. We presume that this may be caused by increased pleural permeability and more rapid passage of a large amount of Gd-DTPA from the blood into the pleural fluid in case of exudative effusions. In our limited group of patients, signal enhancement proved the presence of an exudative effusion. Absence of signal enhancement suggests a transudate, but does not exclude an exudate. (orig.).

Kidneys lymphomas are mainly secondary and represent the most frequent localizations in the urinary tract (68%). The appearance most frequently observed with computed tomography (CT) as well as ultrasound is that of multinodular involvement or, less frequently, of contiguous involvement from retroperitoneal adenopathy in an isolate nodular or tumoral form or in an infiltrating form. The lesions are most often bilateral and involve the lymph nodes, the liver and/or the spleen, especially when the tumor is a metastasis. Lymphoma in the excreting cavities of the bladder is much less frequent. The frequent stasis does no allow obtaining satisfactory urograms for the exploration of the ureters, so that antegrade or retrograde pyelography is often necessary. The lesions of the bladder are well demonstrated by ultrasound and CT exploration. The metastases of lymphoma in the urinary tract are most frequently located in the kidneys, and represent the most frequent malignant kidney tumors. They are often non recognized clinically since they occur at late stages in cancer evolution. Their usual appearance with ultrasound and CT is that of multiple solid-type tumors. Metastases in the excreting cavities of the bladder are very rare [fr

2017-01-01

Lymphoma of the eyelid constitutes 5% of ocular adnexal lymphoma. In previously published cases, 56% of lymphomas of the eyelid are of B-cell origin and 44% are of T-cell origin. The most frequent B-cell lymphomas are extranodal marginal zone lymphoma (27 cases-14%) and diffuse large B......-cell lymphoma (18 cases-9%). T-cell lymphomas are most frequently mycosis fungoides (25 cases-13%), extranodal natural killer/T-cell, nasal-type lymphoma (12 cases-6%), and primary cutaneous anaplastic large-cell lymphoma (12 cases-6%). This distribution differs from the distribution of ocular adnexal lymphoma...... and that of cutaneous lymphoma. The majority of subtypes occur in elderly patients, except for lymphoblastic lymphoma of B-cell and T-cell origin and Burkitt lymphoma, which occur in children and adolescents. Several subtypes have a male predominance, including peripheral T-cell lymphoma and Burkitt lymphoma. Only...

To describe the patient demographics and outcome analysis in paediatric non-Hodgkin lymphoma (NHL) patients. Study Design:An observational study. Place and Duration of Study:The Hematology/Oncology Unit of The Children's Hospital and Institute of Child Health, Lahore, from January 2012 till December 2014. Methodology:Demographics including age, gender, histopathology, stage and outcome data, in biopsy proven NHL patients were analyzed. Burkitts/B Cell and Diffuse Large B Cell lymphoma patients were treated with MCP 842 Protocol while T/B-cell lymphoblastic lymphoma (LL) patients were treated with EURO-LB 02 protocol. Results:Ninety-one patients were treated during the study period at CHL. Data was insufficient in 18 patients, so they were excluded from the study. Patients included were 73. Males were 53 (72.6%). Thirty-seven (50.7%) were 5-10 years of age, and 22 (30.1%) 10-16 years old. Abdominal mass was the commonest presentation seen in 32 (43.8%), lymphadenopathy in 27 (37%), intussusception in 5 (6.8%), while intestinal obstruction, obstructive uropathy, nasopharyngeal mass, gastric mass, primary bone lymphoma, pericardial effusion, jaw swelling, cheek swelling and paraspinal mass present in one (1%) each. Histopathological subtypes consist of Burkitt's lymphoma (BL) in 32 (43.8%), B cell NHL in 10 (13.7%), lymphoblastic lymphoma (LL) in 26 (35.6%), diffuse large B cell lymphoma (DLBCL) in 2 (2.8%), and anaplastic large cell lymphoma (ALCL) in 1 (1.4%). Sixty-seven (91%) presented in stage III, and six (8.4%) in stage IV. Forty-eight (65.8%) patients had completed treatment and are well to date, 16 (21.9%) died, 5 (6.8%) left against medical advice (LAMA), and 4 (5.5%) patients relapsed. Conclusion:Burkitt's lymphoma was the commonest type of NHL seen in this cohort that predominantly presented with an abdominal mass. Children usually presented in advanced stage with delayed diagnosis. Better supportive care can improve the prognosis

Objective: To analyse the clinical characteristics of patients with uterus effusion after irradiation for carcinoma of the cervix. Methods: 151 patients with uterus effusion after irradiation for carcinoma of the cervix were retrospectively analyzed. Results: All these 151 patients who had been treated by radiotherapy had FIGO stage IIB or IIIB lesions including 32 adenocarcinomas. The most common symptom was irregular vaginal discharge or drainage (65 patients), followed by irregular vaginal bleeding (32 patients), and abdominal or pelvic mass (27 patients). Twenty-seven patients were entirely asymptomatic. The positive rate of uterus effusion found by B-ultrasound scan was 100%. When uterus effusion was found, 87 patients (57.6%) had malignant tumor, including 62 with residual or recurrent cervical carcinoma and 25 with secondary primary malignant uterus tumor. Sixty-four patients had uterus effusion alone including 8 with pyometra. Of these 64 patients, 17 underwent abdominal hysterectomy with bilateral salpingo-oophorectomy (BSOH), the others were treated with drainage till the fluid disappeared. Of the 62 patients with residual or recurrent cervical carcinoma, 19 underwent BSOH and 43 were treated by palliative irradiation or chemotherapy. Twenty-five patients who had secondary primary malignant uterus tumor were treated by BSOH. The 5-year survival rate of patients with uterus effusion alone, with residual tumor (with recurrent tumor), or with secondary primary malignancy were 54.8%, 0%, 28.7% and 47.5%, respectively. The prognosis of the patients with uterus effusion alone was better than those with secondary primary malignant uterus tumor. Patients with residual or recurrent cervical cancer had the worst prognosis. Conclusions: Patients with uterus effusion after irradiation for carcinoma of the cervix often have tumor including secondary primary, malignant uterus tumor. The prognosis is different, which depends on if the patient has tumor or not. (authors)

Background Apoptosis plays a role in the development of pleural effusion. Caspase-cleaved cytokeratin 18, a marker for epithelial cell apoptosis, was evaluated in pleural effusion. Methods A total of 79 patients with pleural effusion were enrolled. The underlying causes were lung cancer (n=24), parapneumonic effusion (n=15), tuberculous effusion (n=28), and transudates (n=12). The levels of M30, an epitope of caspase-cleaved cytokeratin 18, were measured in blood and pleural fluids using enzyme-linked immunosorbent assay along with routine cellular and biochemical parameters. The expression of M30 was evaluated in the pleural tissues using immunohistochemistry for M30. Results The M30 levels in pleural fluid were significantly higher in patients with tuberculosis (2,632.1±1,467.3 U/mL) than in patients with lung cancer (956.5±618.5 U/mL), parapneumonic effusion (689.9±413.6 U/mL), and transudates (273.6±144.5 U/mL; all peffusion from all other effusions was 0.93. In the immunohistochemical analysis of M30, all pathologic types of cancer cells showed moderate to high expression, and the epithelioid cells in granulomas showed high expression in tuberculous pleural tissues. Conclusion Caspase-cleaved cytokeratin 18 was most prominently observed in tuberculous pleural effusion and showed utility as a clinical marker. The main source of M30 was found to be the epithelioid cells of granulomas in tuberculous pleural tissues. PMID:24523813

Primary Follicular Lymphoma of the Common Bile Duct Mimicking Cholangiocarcinoma

Full Text Available Primary non-Hodgkin′s lymphoma of the common bile duct is extremely rare. We present a case with history of inflammatory bowel disease and clinical manifestations of obstructive jaundice. Abdominal magnetic resonance imaging with magnetic resonance cholangiopancreatography (MRCP was done and demonstrated tight stricture at the middle part of common bile duct, and radiological findings were supportive of extra-hepatic cholangiocarcinoma. Whipple′s procedure was performed and the case was histopathologically proven to be non-Hodgkin′s lymphoma of follicular subtype involving the common bile duct. Lymphoma of the hepatobiliary system is usually present as secondary manifestation of systemic malignant lymphoma. However, primary malignant lymphomas arising from the hepatobiliary tree are extremely rare. The radiological appearance of common bile duct lymphoma is very similar to cholangiocarcinoma, making preoperative diagnosis very difficult, as in our present case. We also compare the imaging findings of our case to those seen in reported cases of follicular lymphoma of the common bile duct.

IMPORTANCE: To date, the clinical features of the various subtypes of conjunctival lymphoma (CL) have not been previously evaluated in a large cohort. OBJECTIVE: To characterize subtype-specific clinical features of CL and their effect on patient outcome. DESIGN, SETTING, AND PARTICIPANTS...... age was 61.3 years, and 55.1% (145 of 263) were female. All lymphomas were of B-cell type. The most frequent subtype was extranodal marginal zone lymphoma (EMZL) (68.4% [180 of 263]), followed by follicular lymphoma (FL) (16.3% [43 of 263]), mantle cell lymphoma (MCL) (6.8% [18 of 263]), and diffuse...... large B-cell lymphoma (DLBCL) (4.6% [12 of 263). Conjunctival lymphoma commonly manifested in elderly individuals (age range, 60-70 years old), with EMZL having a female predilection (57.8% [104 of 180]) and MCL having a marked male predominance (77.8% [14 of 18]). Unlike EMZL and FL, DLBCL and MCL were...

To investigate the clinical role of Vitamin D in prognosis of Otitis media with effusion. This prospective-controlled study was conducted at otolaryngology department in Duzce University, Turkey. The study group comprised children who were diagnosed with Otitis media with effusion between September 2016 and February 2017. Control group was conducted with children underwent circumcision or inguinal hernia repair operations that confirmed with ENT examination they do not have any sign of otitis media. After 3 months of follow-up without any treatment, unresolved cases who were accepted as chronic otitis media with effusion were operated under general anesthesia for ventilation tube application. Study and control groups were assessed depending on the serum 25(OH)Vitamin D levels at the end of 3 months; otitis media with effusion and chronic otitis media with effusion. One-hundred-seventy-four children with otitis media with effusion and 80 control patients were included to the study. One-hundred-eight (62%) out of 174 patients with otitis media with effusion was completely recovered after a 3-months follow up. Of those 66 out of 174 children, they had persistent diseases, underwent ventilation tube insertion after a 3-months follow-up. The mean 25(OH)Vitamin D level was 18.98 ± 10.60 in otitis media with effusion group and 28.07 ± 14.10 in control group and the difference was statistically significant between the study and control group (p otitis media with effusion group whilst 35 out of 108 patients (32.4%) in complete recovery otitis media with effusion group (p = 0.021). The rate of 25(OH)Vitamin D deficiency was 25% in control group which was statistically different from chronic otitis media with effusion and recovery chronic otitis media with effusion groups (p = 0.006). This study not only shows the relationship between Vitamin D and otitis media with effusion development, but also demonstrates the effects of Vitamin D on otitis media with effusion

A retrospective study of 21 patients who had suffered from gastrointestinal lymphoma was carried out. Gastric involvement was more common than involvement of the small or large intestine and carried a better prognosis. Gastrointestinal lymphoma generally occurs most frequently during the fourth to seventh decades of life. In our study, however, five lymphomas occurred in patients under 20 years of age. Clinical symptoms were nonspecific, and abdominal mass was found in only 15% of the patients on clinical examination. All patients were explored, 17 underwent resection, and 4 laparotomy and biopsy. Five-year survival was much better for patients who had undergone resection. Survival was inversely proportionate to the extent of nodal spread. Multiple lesions on the same organ yielded a 5-year survival of 20%, while a single lesion offered a 55% chance of 5-year survival. Diffuse histiocytic lymphoma was the commonest type, followed by the poorly differentiated lymphocytic type. A longer survival rate was present in the lymphocytic type. However, the highest survival rate was in those patients in whom definite resections of the lesion were performed followed by radiation and chemotherapy, especially for gastric tumor.

Non-Hodgkin's lymphoma - Part II: Management of primary extranodal lymphomas, generalized disease and salvage treatment

Gospodarowicz, Mary K.; Sutcliffe, Simon B.

1996-01-01

Objective: To review the approach to the diagnosis, classification, assessment, treatment and continuing management of patients with primary extranodal non-Hodgkin's lymphoma, and the management of generalized disease with the emphasis on the current role of salvage treatment with high dose chemotherapy and stem cell/bone marrow support strategies. Non-Hodgkin's lymphoma may involve any part of the body. Many lymphomas, such as MALT, angiocentric T-cell, etc., commonly present in extranodal sites. Lymphomas presenting in the GI tract, and head and neck, are most common with the single most common site being the stomach. Gastric lymphoma is associated with Helicobacter pylorii and is most common in areas endemic for Helicobacter pylorii infection. Recent advances in the understanding of the etiology of gastric MALT, thyroid, and intestinal lymphomas present new opportunities for the application of novel therapeutic approaches e.g. antibiotic therapy for Helicobacter pylori and early stage IPSID. Lymphomas presenting in the orbit, thyroid, breast, bone, extradural and skin are of interest because of the importance of expert RT in securing local control. Primary brain lymphomas present a particular challenge to the radiation oncologist. Although localized, primary brain lymphomas are extremely difficult to control. Rare sites of extranodal lymphoma include testis, female genital tract, and lung. Extranodal lymphomas are often localized and cure with RT or CMT is possible. They represent a assorted group of diseases with diverse presentations, prognosis, sensitivity to RT and expected outcome. They are of particular importance to radiation oncologists as they require special attention to patterns of spread and treatment planning. The principles of management of primary extranodal lymphoma, however, follow those applicable to localized nodal presentations. Although primary extranodal lymphomas are highly curable, a proportion of patients will fail with disseminated

Persistent, viscous middle ear effusion in pediatric otitis media (OM) contributes to increased likelihood of anesthesia and surgery, conductive hearing loss, and subsequent developmental delays. Biomarkers of effusion viscosity and hearing loss have not yet been identified despite the potential that such markers hold for targeted therapy and screening. To investigate the association of gel-forming mucins and aquaporin 5 (AQP5) gene expression with inflammation, effusion viscosity, and hearing loss in pediatric OM with effusion (OME). Case-control study of 31 pediatric patients (aged 6 months to 12 years) with OME undergoing tympanostomy tube placement and control individuals (aged 1 to 10 years) undergoing surgery for cochlear implantation from February 1, 2013, through November 30, 2014. Those with 1 or more episodes of OM in the previous 12 months, immunologic abnormality, anatomical or physiologic ear defect, OM-associated syndrome (ie, Down syndrome, cleft palate), chronic mastoiditis, or history of cholesteatoma were excluded from the study. All patients with OME and 1 control were recruited from Children's Hospital of Wisconsin, Milwaukee. The remainder of the controls were recruited from Sick Kids Hospital in Toronto, Ontario, Canada. Two to 3 middle ear biopsy specimens, effusions, and preoperative audiometric data (obtained effusions was assayed using rheometry. Of the 31 study participants, 24 patients had OME (mean [SD] age, 50.4 [31.9] months; 15 [62.5%] male; 16 [66.7%] white) and 7 acted as controls (mean [SD] age, 32.6 [24.4] months; 2 [26.6%] male; 6 [85.7%] white). Mucins and AQP5 gene expression were significantly higher in patients with OME relative to controls (MUC2: ratio, 127.6 [95% CI, 33.7-482.7]; MUC5AC: ratio, 3748.8 [95% CI, 558.1-25 178.4]; MUC5B: ratio, 471.1 [95% CI, 130.7-1697.4]; AQP5: ratio, 2.4 [95% CI, 1.1-5.6]). A 2-fold increase in MUC5B correlated with increased hearing loss (air-bone gap: 7.45 dB [95% CI, 2.65-12.24 d

Several cytokines and innate immune-associated molecules are present in middle ear effusions, but damage-associated molecular patterns (DAMPs) in middle ear effusion have not been studied. Therefore, we evaluated the role of heat shock proteins (Hsps) in the development of otitis media with effusion (OME). Serous middle ear effusions from 22 pediatric patients who were diagnosed with OME and underwent ventilation tube insertion from June 2015 to March 2017 were evaluated in our study. The levels of Hsp 90, 70, 27, IL-8, and TNF-α in effusion fluids were evaluated by enzyme-linked immunosorbent assays. The associations between the levels of these molecules and the degree of tympanic membrane inflammation were statistically evaluated. Finally, the relationships among these molecules were also evaluated. Hsp 70 and Hsp 27 were detected in all middle ear effusions, but Hsp 90 was detected in only five effusion fluid samples. IL-8 was also detected in all middle ear effusions, but TNF-α was detected in only four effusion fluid samples. When we compared the degree of tympanic membrane inflammation with the levels of Hsp 70, Hsp 27, and IL-8, which were detected in all effusion fluids, we could not find statistical significance. However, Hsp 70, Hsp 27, and IL-8 were significantly associated with each other (p effusions. Furthermore, the levels of Hsp 70 and Hsp 27 were positively correlated with each other, and were also positively associated with the neutrophil chemoattractant, IL-8. Our findings suggested that Hsp 70 and Hsp 27 might be involved in the pathophysiology of pediatric OME. Copyright © 2017 Elsevier B.V. All rights reserved.

Non-Hodgkin's lymphoma presenting as a primary bladder tumor: a case report

Directory of Open Access Journals (Sweden)

Molinos-Castro Sonia

2010-04-01

Full Text Available Abstract Introduction Primary lymphoma of the bladder represents 0.2% of all bladder malignancies. Secondary involvement of the bladder by malignant lymphoma occurs in 10% to 50% of cases. Most lymphomas of the bladder are non-Hodgkin's lymphomas of the B-cell type, with preponderance among women. The impact of positron emission tomography (PET on tumor staging has recently become very important due to its use in the study of diagnosis extension and individual therapy design. Case presentation We report the case of a 79-year-old Caucasian man with intermittent haematuria as the presenting symptom of non-Hodgkin's lymphoma of the bladder. He was first diagnosed with primary lymphoma of the bladder using the current staging method, but a positron emission tomography study subsequently revealed that he instead had a secondary involvement of the bladder. Conclusion The staging of non-Hodgkin's lymphomas, which is useful in order to plan accurate therapy, has been changing since the introduction of positron emission tomography scanning. Primary lymphomas of the bladder, although very rare, may be even more uncommon when this imaging technique is used to assess the extension of the disease. Although the interpretation of this technique has some limitations that should be taken into account, the extensive use of positron emission tomography should nonetheless help improve the diagnosis of this disease.

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.

2010-01-01

Objective: To study the clinical usefulness of combined detection of tumor markers in effusion fluid in patients with malignant pleural effusion or ascites. Methods: Combined detection of six tumor markers (CA125, CA50, CA15-3, CYFRA21-1, βHCG, HCG) in effusion fluid was performed in 92 patients with malignant pleural effusion and 78 patients with malignant ascites as well as 100 control benign specimens. These tumor markers were examined with CLIA, except CA50, which was examined with RIA. Exfoliative cytology was also examined in the malignant specimens. Results: The positive rate of these markers was highest with CA125, followed by CA50, CA15-3, CYFRA21-1, βHCG and HCG in order. βHCG and HCG, though with quite low positive rate, were still useful markers due to the almost zero false-positive rate, i.e. very high specificity. For combined determination of two markers, CA15 + CYFRA21-1 or CA125 + CA50 would result in the highest positive rate. For highly suspected but undetermined cases, the following criteria for malignancy would be helpful: (1) two or more positive among CA125, CA50, CA15-3, CYFRA21-1 (2) One of the four CAs positive + either βHCG or HCG (3) Both βHCG and HCG positive. Tumor markers positiveness would be supplementary to doubtful cytological studies. Conclusion: Combined detection of tumor markers in effusion fluid would be very helpful for diagnosis of malignancy.

γ-Herpesvirus load as surrogate marker of early death in HIV-1 lymphoma patients submitted to high dose chemotherapy and autologous peripheral blood stem cell transplantation.

Directory of Open Access Journals (Sweden)

Chiara Pratesi

Full Text Available Autologous stem cell transplantation (ASCT is a feasible procedure for human immunodeficiency virus-1 (HIV-1 lymphoma patients, whose underlying disease and intrinsic HIV-1- and ASCT-associated immunodeficiency might increase the risk for γ-herpesvirus load persistence and/or reactivation. We evaluated this hypothesis by investigating the levels of Epstein-Barr virus (EBV- and Kaposi sarcoma-associated herpesvirus (KSHV-DNA levels in the peripheral blood of 22 HIV-1-associated lymphoma patients during ASCT, highlighting their relationship with γ-herpesvirus lymphoma status, immunological parameters, and clinical events. EBV-DNA was detected in the pre-treatment plasma and peripheral blood mononuclear cells (PBMCs of 12 (median 12,135 copies/mL and 18 patients (median 417 copies/10(6 PBMCs, respectively; the values in the two compartments were correlated (r = 0.77, p = 0.0001. Only EBV-positive lymphomas showed detectable levels of plasma EBV-DNA. After debulking chemotherapy, plasma EBV-DNA was associated with lymphoma chemosensitivity (p = 0.03 and a significant higher mortality risk by multivariate Cox analysis adjusted for EBV-lymphoma status (HR, 10.46, 95% CI, 1.11-98.32, p = 0.04. After infusion, EBV-DNA was detectable in five EBV-positive lymphoma patients who died within six months. KSHV-DNA load was positive in only one patient, who died from primary effusion lymphoma. Fluctuations in levels of KSHV-DNA reflected the patient's therapy and evolution of his underlying lymphoma. Other γ-herpesvirus-associated malignancies, such as multicentric Castleman disease and Kaposi sarcoma, or end-organ complications after salvage treatment were not found. Overall, these findings suggest a prognostic and predictive value of EBV-DNA and KSHV-DNA, the monitoring of which could be a simple, complementary tool for the management of γ-herpesvirus-positive lymphomas in HIV-1 patients submitted to ASCT.

Full Text Available We describe the case of a patient with long-standing Parkinson's disease and recurrent bilateral pleural effusions. The pleural fluid was an exudate, rich in normal lymphocytes, and the echocardiogram, chest computerized axial tomography, and immunological, microbiological and cytological studies were negative. The patient had been taking bromocriptine, which can be related to chronic pleural effusions. Using Pubmed, we found about 40 cases of pleuropulmonary changes or constrictive pericarditis that were related to bromocriptine. We decided to suspend this drug, with resolution of the pleural effusion and respiratory complaints for more than a year now. We discuss possible underlining mechanisms for this and emphasize the importance of collecting the past medical history and medication and of considering possible iatrogenic effects.

Lymphoblastic lymphoma is the second most common type of non-Hodgkin lymphoma seen in children. Approximately, 90% of lymphoblastic lymphomas arise from T cells, with the remaining 10% being B-cell-lineage derived. Although T-cell lymphoblastic lymphoma most frequently occurs in the anterior mediastinum (thymus), B-cell lymphoblastic lymphoma (B-LBL) predominates in extranodal sites such as skin and bone. Here, we describe a pediatric B-LBL patient who presented with extensive abdominal involvement and whose lymphoma cells displayed segmental duplication of the mixed lineage leukemia (MLL) gene. MLL duplication/amplification has been described primarily in acute myeloid leukemia and myelodysplastic syndrome with no published reports of discrete MLL duplication/amplification events in B-LBL. The MLL gene duplication noted in this case may represent a novel mechanism for tumorigenesis in B-LBL.

Pleural separation, the "split pleura" sign, has been reported in patients with empyema. However, the diagnostic yield of the split pleura sign for complicated parapneumonic effusion (CPPE)/empyema and its utility for differentiating CPPE/empyema from parapneumonic effusion (PPE) remains unclear. This differentiation is important because CPPE/empyema patients need thoracic drainage. In this regard, the aim of this study was to develop a simple method to distinguish CPPE/empyema from PPE using computed tomography (CT) focusing on the split pleura sign, fluid attenuation values (HU: Hounsfield units), and amount of fluid collection measured on thoracic CT prior to diagnostic thoracentesis. A total of 83 consecutive patients who underwent chest CT and were diagnosed with CPPE (n=18)/empyema (n=18) or PPE (n=47) based on the diagnostic thoracentesis were retrospectively analyzed. On univariate analysis, the split pleura sign (odds ratio (OR), 12.1; ppleural effusion (≥30 mm) (OR, 6.13; ppleural fluid were significantly higher in the CPPE/empyema group than in the PPE group. On multivariate analysis, only the split pleura sign (hazard ratio (HR), 6.70; 95% confidence interval (CI), 1.91-23.5; p=0.003) and total amount of pleural effusion (≥30 mm) on thoracic CT (HR, 7.48; 95%CI, 1.76-31.8; p=0.006) were risk factors for empyema. Sensitivity, specificity, positive predictive value, and negative predictive value of the presence of both split pleura sign and total amount of pleural effusion (≥30 mm) on thoracic CT for CPPE/empyema were 79.4%, 80.9%, 75%, and 84.4%, respectively, with an area under the curve of 0.801 on receiver operating characteristic curve analysis. This study showed a high diagnostic yield of the split pleura sign and total amount of pleural fluid (≥30 mm) on thoracic CT that is useful and simple for discriminating between CPPE/empyema and PPE prior to diagnostic thoracentesis.

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.

The Prevalence of Pleural Effusion in Pregnant Women: A Pilot Study

Pleural effusions are very common in general population. There are more than 50 reasons for the etiology. There is limited data on the prevalence of pleural effusions in a population of pregnant women. We prospectively screened 45 pregnant women between May and October 2006. All the pregnant women underwent thoracic ultrasonography during their routine check. Five out of 45 subjects (11%) had minimal and bilateral pleural effusion. None of the subjects was symptomatic. All of the effusions re...

Full Text Available Pleural effusions are rare in the newborn. Still, being familiar with this condition is relevant given its association with a wide range of disorders. Only two large series of cases on this matter have been published, with no solid conclusions established. The aim of this study is to determine the etiology, management and prognosis of pleural effusions in a population of high-risk neonates.The authors performed a retrospective study in the Neonatal Intensive Care Unit of "Hospital de São João", Porto (Portugal, between 1997 and 2014, of all newborns with the diagnosis of pleural effusion, chylothorax, hemothorax, empyema, fetal hydrops or leakage of total parenteral nutrition (TPN.Eighty-two newborns were included, 48 males and 34 females. Pleural effusions were congenital in 19 (23.2% newborns and acquired in 63 (76.8%. Fetal hydrops was the most frequent cause (15 cases, 78.9% of congenital effusions while postoperative after intrathoracic surgery was the most common cause (39 cases, 61.9% of acquired effusions, followed by leakage of TPN (13 cases, 20.6%. Chylothorax was the most common type of effusion (41.5% of cases. Pleural effusions after intrathoracic surgery were mainly (64.1% chylothoraces. Regarding use of octreotide for treatment of acquired chylous effusions, the comparative analysis showed no statistical differences between the group of alive newborns who received octreotide and the group who did not. Twenty-seven (32.9% newborns died; the causes of death were related to underlying diseases and not to the pleural effusion. Clinical outcome is generally good, except in hydropic neonates. Blood albumin level appears to be predictive of prognosis and further investigation on its clinical significance should be encouraged.

Hydrops fetalis (HF) has a low survival rate, particularly in the case of preterm birth. In addition, the severity index of HF has not been fully investigated yet. The aim of this study was to clarify the prognostic factors of HF with pleural effusion. All live-born HF patients with pleural effusion, except for chromosomal abnormality or complex congenital heart disease, born from 2009 to 2013 in Aichi Prefecture in Japan were included. Prenatal, perinatal, and postnatal information was obtained from the medical records and was retrospectively analyzed. Forty-one HF patients with pleural effusion were included, and 28 patients (68%) survived. On multivariate logistic stepwise analysis, gestational birth week (OR, 0.71; 95% CI: 0.52-0.96, P = 0.027) and standard deviation (SD) score of the birthweight (OR, 1.74; 95% CI: 1.01-2.99, P = 0.045) were significant factors for postnatal death.

L. Bozzola

2011-09-01

Full Text Available The frequency of pericardial involvement in Systemic Sclerosis (SSc is high on autoptic or echocardiographic studies, but the clinical recognition of pericarditis with or without effusion is rare. We describe a case of a 71-year-old female with no previous history of heart disease, who presented with a large pericardial effusion and tamponade that required pericardial drain. She had suffered from Raynaud’s phenomenon since 25 years. Six weeks after hospital discharge she complained of skin hardening on left leg. Pericardial tamponade is a very rare manifestation of SSc and occurs both early or late in the course of the disease, but in our case it preceded the recognition of scleroderma. We have only identified two other cases of pericardial effusion preceding cutaneous involvement in scleroderma.

Pleural effusion induced by sarcoidosis is rare, and pleural sarcoidosis is often diagnosed by thoracoscopic surgery. 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

The aims of this study were as follows: to analyze the forkhead box M1 (FoxM1) expression in benign and malignant pleural effusion by reverse transcription-polymerase chain reaction assay (RT-PCR); to explore the role of FoxM1 in formation and progress in malignant pleural effusion, and whether there is significant difference in expression level of FoxM1 between benign and malignant pleural effusion; to seek a gene marker diagnostically useful to identify benign and malignant pleural effusion in diagnosis and treatment of pleural effusion; and to collect expression level data of FoxM1 in 23 malignant pleural effusion samples (17 adenocarcinoma samples, four squamous carcinoma samples and two small cell lung carcinoma samples) and 15 benign pleural effusion samples (11 inflammatory pleural effusions, two transudates, two tuberculous pleural effusions) by RT-PCR. Among all 38 samples, average FoxM1 expression level of benign pleural effusions is (235.09 ± 59.99), while malignant pleural effusions (828.77 ± 109.76). Among 23 malignant samples, average FoxM1 expression level is (529.27 ± 75.85) in samples without cytological diagnostic evidence, while (1,218.12 ± 167.21) in samples with cytological diagnostic evidence. Differences of FoxM1 expression level between benign pleural effusions and malignant ones have statistical significance. There is an area of 0.881 under the receiver-operating characteristic curve, which verifies the accuracy of using FoxM1 expression level as diagnostic index to identify benign and malignant pleural effusions. According to our study, diagnostic sensitivity and specificity for FoxM1 expression level at 418.1 were 82.6 and 86.7 %, respectively, while 47.8 and 100 %, respectively, at 768.7. FoxM1 expression level in malignant pleural effusions is significantly higher than in benign ones. This study provides a new approach in clinical diagnosis, with FoxM1 as a specific molecule marker to identify benign and malignant pleural

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.

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).

Historical notes are presented tracing the development of the effusion methods along with some fundamental equations to be used later. Theoretical and experimental limitations of the method, and of each variant of the effusion method are cited. How these problems have been dealt with and where our understanding of them now lies are discussed, and estimates of the accuracy with which derived results can be ascribed are given. Finally, some newer techniques are mentioned which give some of the same results that have traditionally been obtained by effusion studies, try to place them in perspective, and perhaps suggest some future directions for effusion studies

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.

To evaluate the effects of otitis media with effusion on surgical parameters, patient safety, perioperative and postoperative complications. Total 890 children who underwent cochlear implantation between 2006 and 2015 were included. The ages ranged from 12 months to 63 months (mean: 32 months). The patients were divided into two groups according to the presence or absence of otitis media with effusion; otitis media with effusion group and non-otitis media group. Of 890 children, 105 had otitis media with effusion prior to surgery. In non-otitis media with group, there were 785 children. The average duration of surgery was 60min (ranged from 28 to 75min) in non-otitis media group, and 90min (ranged from 50 to 135min) in otitis media with effusion group (peffusion during the surgery. There was no significant difference between the complications of groups with or without otitis media with effusion (p>0.05). In 5 of 105 patients, there was a ventilation tube inserted before cochlear implantation, which did not change the outcome of implantation. There is no need for surgical treatment for otitis media with effusion before implantation since otitis media with effusion does not increase the risks associated with cochlear implantation. Operation duration is longer in the presence of otitis media with effusion. However, otitis media with effusion leads to intraoperative difficulties like longer operation duration, bleeding, visualization of the round window membrane, cleansing the middle ear granulations as well as mastoid and petrous air cells.

To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2,500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score otitis media with effusion. Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. Copyright © 2015 Sociedade de Pediatria de São Paulo.

Background/Aim: A pleural effusion is an abnormal collection of fluid in the pleural space and may cause related morbidity or mortality in cirrhotic patients. Currently, there are insufficient data to support the long-term prognosis for cirrhotic patients with pleural effusion. In this study, we investigated the short- and long-term effects of pleural effusion on mortality in cirrhotic patients and evaluated the benefit of liver transplantation in these patients. Patients and Methods: The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify 3,487 cirrhotic patients with pleural effusion requiring drainage between January 1, 2007 and December 31, 2010. The proportional hazards Cox regression model was used to control for possible confounding factors. Results: The 30-day, 90-day, 1-year, and 3-year mortalities were 20.1%, 40.2%, 59.1%, and 75.9%, respectively, in the cirrhotic patients with pleural effusion. After Cox proportional hazard regression analysis adjusted by patient gender, age, complications of cirrhosis and comorbid disorders, old age, esophageal variceal bleeding, hepatocellular carcinoma, hepatic encephalopathy, pneumonia, renal function impairment, and without liver transplantation conferred higher risks for 3-year mortality in the cirrhotic patients with pleura effusion. Liver transplantation is the most important factor to determine the 3-year mortalities (HR: 0.17, 95% CI 0.11- 0.26, P effusion predicts poor long-term outcomes. Liver transplantation could dramatically improve the survival and should be suggested as soon as possible. PMID:29451184

OX40, a member of the TNF receptor superfamily, and its ligand (OX40L) play crucial roles in induction and maintenance of integrated T cell immune response. Engagement of OX40L delivers a costimulatory signal to T cells. In this study, we investigated whether inoculation of OX40L-transfected EL4, a murine T cell lymphoma cell line, could induce anti-lymphoma immunity in mice. Female C57BL/6 mice were inoculated with 1 x 10(5) cells of parental EL4, OX40L-transfected EL4 (EL4-OX40L), or mock control vector-transfected EL4 (EL4-mock), and then the tumor size, overall survival, CTL activity of spleen cells, and the immunohistochemistry were compared. While both parental EL4 and EL4-mock grew rapidly, EL4-OX40L was rejected or grew slower than parental EL4 or EL4-mock. Pretreatment of mice with either anti-CD4 or anti-CD8 mAb accelerated the growth of EL4-OX40L, suggesting that both CD4+ and CD8+ T cells were involved in anti-lymphoma immunity. The immunohistochemical study revealed the infiltration of CD8+ T cells into the tumor of EL4-OX40L. In vitro CTL assay demonstrated that spleen cells of mice that had rejected EL4-OX40L had significant cytotoxic activity against parental EL4. The gene transfer of OX40L into lymphoma cells is an eligible and efficient modality to induce anti-lymphoma immunity.

2017-01-01

With this case report, we would like to underline the importance of making a correct diagnosis of any pleural effusion as soon as possible by at least a thoracocentesis. If untreated, tuberculosis may easily disseminate to other organs. Some considerations and suggestions for antibiotic treatment of pleural effusion will also be given, since many antibiotics have some anti-tuberculosis effect and may delay the diagnosis of this infectious disease.

Pleural effusion is a clinical manifestation shared by several underlying pathologies. The differential diagnosis is based on the clinical history, the physical examination, the analysis of the pleural fluid, and the laboratory data (mainly blood tests). There are cases, such as the patient described, where TC is not enough, and unusual imaging techniques are required for the study of pleural effusion, i.e. magnetic resonance cholangiography, cholangiopancreatography (MRCP) and endoscopic ret...

Keeling, A. N.; Leong, S.; Logan, P. M.; Lee, M. J.

2008-01-01

Empyema and complicated pleural effusion represent common medical problems. Current treatment options are multiple. The purpose of this study was to access the outcome of image-guided, small-bore catheter drainage of empyema and effusion. We evaluated 93 small-bore catheters in 82 patients with pleural effusion (n = 30) or empyema (n = 52), over a 2-year period. Image guidance was with ultrasound (US; n = 56) and CT (n = 37). All patients were followed clinically, with catheter dwell times, catheter outcome, pleural fluid outcome, reinsertion rates, and need for urokinase or surgery recorded. Ninety-three small-bore chest drains (mean=10.2 Fr; range, 8.2-12.2 Fr) were inserted, with an average dwell time of 7.81 days for empyemas and 7.14 days for effusions (p > 0.05). Elective removal rates (73% empyema vs 86% effusions) and dislodgement rates (12% empyema vs 13% effusions) were similar for both groups. Eight percent of catheters became blocked and 17% necessitated reinsertion in empyemas, with no catheters blocked or requiring reinsertion in effusions (p < 0.05). Thirty-two patients (51%) required urokinase in the empyema group, versus 2 patients (6%) in the effusion group (p < 0.05). All treatment failures, requiring surgery, occurred in the empyema group (19%; n = 12; p < 0.05). In conclusion, noninfected pleural collections are adequately treated with small-bore catheters, however, empyemas have a failure rate of 19%. The threshold for using urokinase and larger-bore catheters should be low in empyema

Objective: To describe the general findings of lymphoma and their histological patterns in patients less than 20 years old. Materials And Methods: Twenty-two cases (16 male and 6 female, mean age 11.5 years) from the digital archive of computed tomography at the Cancer Control Center of Hospital Universitario Pedro Ernesto - Universidade do Estado do Rio de Janeiro, Rio de Janeiro, RJ, Brazil, were retrospectively analyzed in the period between March 2003 and July 2005. Of these 22 cases, 12 were Hodgkin's and 10 were non-Hodgkin's. Results: Overall, mediastinal lymphadenomegaly was the most frequent finding (59%), with predominance in the Hodgkin's subgroup (75%), followed by hepatosplenomegaly (50%) and cervical and retroperitoneal lymphadenomegaly (27.3%). The Hodgkin's subgroup presented a prevalence of lymphadenopathy, in many lymph node chains, followed by hepatosplenomegaly (50%). One case was found with unilateral tonsillar mass, pulmonary ground-glass opacities, and renal nodules. In the non-Hodgkin's subgroup, the disease was predominantly extranodal, characterized by hepatosplenomegaly (50%), thickening of the intestinal wall (40%), pleural effusion (30%), pulmonary nodule (20%), ascites (10%), pericardial effusion (10%) and mixed bone lesions (10%). Conclusion: Computed tomography is an extremely useful method for detection, staging and follow-up of lymphomas, with alert findings like mediastinal lymphadenopathy, hepatosplenomegaly, unilateral tonsillar mass and thickening of intestinal wall.

Fifty per cent of children with serous otitis media may have some balance disturbances. To evaluate vestibular function in children with otitis media with effusion. The control group comprised 25 children with bilateral normal hearing and middle-ear function. The study group consisted of 30 children with bilateral otitis media with effusion; these were divided into 2 subgroups according to air-bone gap size. Measures included the Arabic Dizziness Handicap Inventory, an imbalance evaluation sheet for children, vestibular bedside tests for children, and air- and bone-conducted vestibular-evoked myogenic potential testing. Arabic Dizziness Handicap Inventory scores and some vestibular bedside test results were significantly abnormal, with normal video-nystagmography results, in children with otitis media with effusion. Air-conducted vestibular-evoked myogenic potentials were recorded in 73 per cent of children with otitis media with effusion, with significantly delayed latencies. Bone-conducted vestibular-evoked myogenic potentials were successfully detected in 100 per cent of children with otitis media with effusion with similar results to the control group. The Arabic Dizziness Handicap Inventory and vestibular bedside tests are valuable tools for detecting vestibular impairment in children. Bone-conducted vestibular-evoked myogenic potentials are useful for vestibular system evaluation.

Primary cardiac lymphoma is defined as non-Hodgkin lymphoma involving the heart and/or pericardium. It is a rare cancer that primarily affects the right heart and in particular the right atrium. By contrast, renal cell carcinoma is a relatively common cancer, which in rare circumstances can metastasize to the heart. It is now known that there is an association between non-Hodgkin lymphoma and renal cell carcinoma, although the underlying mechanisms are not fully understood. The authors present a case of primary cardiac non-Hodgkin lymphoma in a patient with concomitant renal cell carcinoma and explore the possible reasons for this association.

Mandel, E M; Rockette, H E; Bluestone, C D; Paradise, J L; Nozza, R J

1987-02-19

In a randomized, double-blind, placebo-controlled trial involving 518 infants and children who had otitis media with effusion ("secretory" otitis media), we evaluated the efficacy of a two-week course of amoxicillin (40 mg per kilogram of body weight per day) with and without a four-week course of an oral decongestant-antihistamine combination. Among the 474 subjects who were evaluated at the four-week end point, the rate of resolution of middle-ear effusion was twice as high in those treated with amoxicillin, either with or without the decongestant-antihistamine, as in those who received placebo (P less than 0.001), but 69.8 percent of the amoxicillin-treated subjects still had effusion. Among both the amoxicillin-treated subjects and the placebo-treated subjects, resolution was more likely in those with initially unilateral effusion, in those who had had effusion for eight weeks or less, and in those without an upper respiratory tract infection at the four-week end point. Side effects were reported more often in subjects who received decongestant-antihistamine than in those who did not. Among the subjects without effusion at the four-week end point, recurrent effusion developed in approximately half those in both the amoxicillin and placebo groups during the subsequent three months. We conclude that in infants and children with otitis media with effusion, amoxicillin treatment increases to some extent the likelihood of resolution.

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 (psplenic 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.

Sun Jia; Jing Xiufeng; Hui Fuxin

2010-01-01

Objective: To explore differential diagnostic value of procalcitonin (PCT), adenosine deaminase (ADA) in pleural fluid and serum for tuberculous pleural effusions. Methods: The concentrations of PCT and ADA both in serum and pleural fluid in one hundred and twenty-eight patients with pleural effusion were detected. These patients were divided into three groups. Fifty-two patients with tuberculous plueral effusion were composed of the tuberculous group. Twenty-two patients with parapneumonic effusion composed the pneumonic group and forty patients with malignant pleural effusion and fourteen patients with heart faliure composed of the control group. Results: There were no statistically significant differences in serum PCT among the three groups (P > 0.05). PCT of pleural fluid was significantly increased in tuberculous and parapneumonic groups compared to the control group (P < 0.05). ADA activities in tuberculous serum and pleural fluid were both higher than those in the parapneumonic and the control groups (P < 0.01). The ratio of ADA in pleural fluid and serum (P /S) was calculated. The diagnostic sensitivity and specificity of P /S (cut-off value 1.27) were 92.3% and 100% respectively for tuberculous pleural effusions calcuted by receiver operating curve. Conclusion: Combined measurements of PCT and ADA in pleural fluid are useful in diagnosing tuberculous pleural effusions. (authors)

To determine the frequency of various causative factors of pleural effusion in adults. Combined Military Hospital, Attock and PAF hospital Faisal Karachi. One hundred and fifty patients of clinical signs of pleural effusion, were selected and then, further classified in to transudative and exudative variety by carrying out pleural fluid routine testing and using Light's criteria . Later the final etiological diagnosis was made with the help of appropriate laboratory tests. Out of total 150 patients who were studied, 123 patients were found to have exudative effusions whereas 27 cases had transudative effusion. A total of five 5 patients (3.33%) were lost to follow up. Three patients were out of exudative variety and 02 were from transudative variety. Out of 120 patient of exudative pleural effusion, 70(58.2%) had tuberculosis, 28(23.2%) had malignancy, 12(10%) had pneumonia, 5(6%) were uraemic, 2(1.6%) had pulmonary embolism, and rheumatoid arthritis, Systemic lupus erythematosis and liver abscess were causative factors in 1(0.8%) each patient. Out of transudative effusions, 14(56%) had congestive cardiac failure, 5(20%) had cirrhosis liver, 4(16%) had nephrotic syndrome and 1(4%) each had cardiac tamponade and myxoedema. The most common cause of pleural effusion remains tuberculosis. (author)

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.

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.

Thirty-three patients with pericardial effusion after open heart surgery were investigated with computed tomography (CT). Twelve of the 33 patients also underwent echocardiography prior to pericardiocentesis. The effusions were typed according to the results of the CT investigation. Because of postoperative adhesions, typical patterns of localized pericardial effusions were found in 16 patients. The localized compartments were seen on the right and left side of the heart and around the aorta and the pulmonary artery. CT was therefore shown to be of value for selecting the approach for drainage with catheter pericardiocentesis. (orig.)

Deregulated MYC is found in about half of human tumors, being more prevalent in hematological neoplasms. Deregulation mechanisms include chromosomal translocation (particularly in lymphoma, amplification, and hyperactivation of MYC transcription. Here we review MYC involvement in the major types of leukemia and lymphoma. MYC rearrangements appear in all Burkitt lymphomas and are common in other lymphoma types, whereas in acute lymphoblastic leukemia, acute myeloid leukemia, lymphoproliferative, and myeloproferative diseases, they are less frequent. However, MYC overexpression is present in all types of hematological malignancies and often correlates with a worse prognosis. Data in leukemia-derived cells and in animal models of lymphomagenesis and leukemogenesis suggest that MYC would be a good therapeutic target. Several MYC-directed therapies have been assayed in preclinical settings and even in clinical trials. First, peptides and small molecules that interrupt the MYC–MAX interaction impair MYC-mediated tumorogenesis in several mouse models of solid tumors, although not yet in lymphoma and leukemia models. Second, there are a number of small molecules inhibiting the interaction of MYC–MAX heterodimers with DNA, still in the preclinical research phase. Third, inhibitors of MYC expression via the inhibition of BRD4 (a reader of acetylated histones have been shown to control the growth of MYC-transformed leukemia and lymphoma cells and are being used in clinic trials. Finally, we review a number of promising MYC

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 (Ppleural effusion. The efficacy of the procedure is related to the separation of pleural effusion, drainage tube type and tube diameter. PMID:28105155

To investigate evidence for selected vector-borne pathogen infections in dogs with pericardial effusion living in a Mediterranean area in which several canine vector-borne diseases are endemic. Archived EDTA blood (n=68) and pericardial fluid samples (n=58) from dogs with pericardial effusion (n=68) were included. Dogs without pericardial effusion examined for other reasons were included as controls (n=60). Pericardial effusion was classified as neoplastic in 40 dogs, idiopathic in 23 dogs and of unknown aetiology in 5 dogs. Real-time PCR was performed for Leishmania infantum, Ehrlichia/Anaplasma species, Hepatozoon canis, Babesia species, Rickettsia species and Bartonella species, and sequencing of PCR products from positive samples was used to confirm species specificity. Vector-borne pathogens were found in 18 dogs: 16 of 68 dogs with pericardial effusion (23·5%) and two of 60 control dogs (3·3%). Positive dogs demonstrated DNA of Leishmania infantum (n=7), Anaplasma platys (n=2, one dog coinfected with Leishmania infantum), Babesia canis (n=5), Babesia gibsoni (n=3) and Hepatozoon canis (n=2). Vector-borne pathogens were more commonly detected among dogs with pericardial effusion than controls (P=0·001). There was no relationship between aetiology of the pericardial effusion and evidence of vector-borne pathogens (P=0·932). Vector-borne pathogens are often detected in dogs with pericardial effusion and require further investigation, especially in dogs with idiopathic pericardial effusion. PCR can provide additional information about the potential role of vector-borne pathogens in dogs with pericardial effusion living in endemic areas. © 2018 British Small Animal Veterinary Association.

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.

Composite lymphoma: Mycosis fungoides with hodgkin′s lymphoma

Mehta Jalpa

2005-01-01

Full Text Available Mycosis fungoides (MF is a malignant lymphoma, primarily of the skin and is characterized by infiltration of the skin by atypical T-cells which have a tendency for epidermotropism. Hodgkins disease (HD is considered to be a malignant lymphoma affecting predominantly the lymph nodes and characterized by presence of Reed- Sternberg cells on histopathology, though, the exact origin of the Reed Sternberg cell and the nature of the malignant cell is not known yet. Few cases of association of mycosis fungoides with Hodgkin′s lymphoma have been reported in the literature. It was reported in the past that when mycosis fungoides spreads to the lymph nodes and other viscera it frequently gets transformed into a more common lymphoma like Hodgkin′s lymphoma. However it has now been proved that the two malignancies are distinct and that such patients probably have a tumour diathesis.

2016-06-01

Full Text Available Abstract Objective: To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Methods: Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position, type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. Results: 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score <7 and day care attendance. The multivariate analysis showed that artificial feeding is the factor most often associated to otitis media with effusion. Conclusions: Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding.

Thermal microscopes are a useful technology to investigate the spatial distribution of the thermal transport properties of various materials. However, for high thermal effusivity materials, the estimated values of thermophysical parameters based on the conventional 1D heat flow model are known to be higher than the values of materials in the literature. Here, we present a new procedure to solve the problem which calculates the theoretical temperature response with the 3D heat flow and measures reference materials which involve known values of thermal effusivity and heat capacity. In general, a complicated numerical iterative method and many thermophysical parameters are required for the calculation in the 3D heat flow model. Here, we devised a simple procedure by using a molybdenum (Mo) thin film with low thermal conductivity on the sample surface, enabling us to measure over a wide thermal effusivity range for various materials.

Pleural effusion is a complicating feature of many diseases of the lung and pleura, but its effects on the mechanics of the diaphragm have not been assessed. In the present study, radiopaque markers were attached along muscle bundles in the midcostal region of the diaphragm in anesthetized dogs, and the three-dimensional location of the markers during relaxation before and after the stepwise introduction of liquid into the left or right pleural space and during phrenic nerve stimulation in the same conditions was determined using computed tomography. From these data, accurate measurements of diaphragm muscle length and displacement were obtained, and the changes in pleural and abdominal pressure were analyzed as functions of these parameters. The effect of liquid instillation on the axial position of rib 5 was also measured. The data showed that 1) liquid leaked through the dorsal mediastinal sheet behind the pericardium so that effusion was bilateral; 2) effusion caused a caudal displacement of the relaxed diaphragm; 3) this displacement was, compared with passive lung inflation, much larger than the cranial displacement of the ribs; and 4) the capacity of the diaphragm to generate pressure, in particular pleural pressure, decreased markedly as effusion increased, and this decrease was well explained by the decrease in active muscle length. It is concluded that pleural effusion has a major adverse effect on the pressure-generating capacity of the diaphragm and that this is the result of the action of hydrostatic forces on the muscle.
