    Nasal type natural killer/T-cell lymphoma is a rare type of extranodal non-Hodgkin lymphoma which originates from nasal cavity and paranasal sinuses. Exact diagnosis of nasal natural killer/T-cell lymphoma, which is a rapidly progressive clinical condition, may be established by immunohistochemical analysis on biopsy material after clinical suspicion. In this article, we report four cases of nasal natural killer/T-cell lymphoma who were followed-up in our clinic and discuss the diagnosis and treatment of the disease in light of the literature data.

    Full Text Available Since nasal NK/T-cell lymphoma and NK/T-cell lymphoma nasal type are rare diseases, colonic involvement has seldom been seen. We report a case of a patient with a primary NK/T-cell lymphoma nasal type of the colon. The patient had no history of malignant diseases and was diagnosed after exhaustive study in the context of fever of unknown origin. The first therapeutic approach followed the DAEPOCH-protocol: etoposide, prednisone, doxor-rubicin, vincristine and cyclophosphamide. The persistence of constitutional symptoms after the first treatment course motivated the switch to a second line following the SMILE-protocol: dexamethasone, metotrexate, ifosfamide, E.coli L-asparaginase, and etoposide. Despite intensive chemotherapy, the patient died 2 months after the diagnose of an extranodal NK/T-cell lymphoma of the colon and 4 months after the first symptomatic appearance of disease.

    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.

    Extranodal NK/T-Cell lymphoma, nasal type (NKTLN) is a disease that mainly affects the nasal cavity and the paranasal sinuses. Early nasal symptoms are nonspecific, simulating sinus infection. With disease progression, necrosis of the nasal mucosa increases, hindering histological diagnosis. Thus, multiple biopsies may be necessary until definitive diagnosis. Most studies on NKTLN address the hematological and immunological aspects of the disease. To present data from a Brazilian quaternary hospital, with emphasis on the clinical aspects of the disease, and to correlate the findings with the most recent literature data. Case study of seven patient files. Patients were evaluated on their medical history, number of biopsies necessary, association with Epstein-Barr virus, treatment, and outcome. All patients had nonspecific nasal complaints and underwent at least three cycles of antibiotic therapy. The earlier a biopsy was performed, the fewer biopsies were required to diagnose the disease and start treatment. However, this fact did not translate into better prognosis. The otolaryngologist plays a fundamental role in the prognosis of NKTLN and can shorten time between symptom onset and treatment of the patient.

    Extranodal natural killer/T cell lymphoma, nasal type (ENKTL) is an aggressive disease with a poor prognosis, requiring risk stratification in affected patients. We designed a new prognostic model specifically for ENKTL to identify high-risk patients who need more aggressive therapy. We retrospectively reviewed 158 patients who were newly diagnosed with ENKTL. The estimated 5-year overall survival rate was 39.4 %. Independent prognostic factors included total protein (TP) 100 mg/dL, and Korean Prognostic Index (KPI) score ≥2. We constructed a new prognostic model by combining these prognostic factors: group 1 (64 cases (41.0 %)), no adverse factors; group 2 (58 cases (37.2 %)), one adverse factor; and group 3 (34 cases (21.8 %)), two or three adverse factors. The 5-year overall survival (OS) rates of these groups were 66.7, 23.0, and 5.9 %, respectively (p KPI model alone (p KPI model alone.

    Purpose/Objective: Lethal midline granuloma (LMG) is disorder characterized by progressive, unrelenting ulceration, and necrosis of the nasal cavity and midline facial tissues. Several investigators have demonstrated that LMG (polymorphic reticulosis) is a peripheral T-cell lymphoma, and the term nasal T-cell lymphoma of the LMG type (LMG-NTL) has since been widely used. Recently, expression of the natural killer (NK) cell marker CD56 on tumor cells has been reported in some cases. However, there is very little information about the optimal treatment for this disease. In this study, we report our observations on the clinical behavior of this tumor in comparison with nasal lymphoma of non-LMG-NTL type (non-LMG-NTL) that makes tumor mass and paranasal sinus lymphoma (PSL) to improve management of LMG-NTL. Materials and Methods: Sixteen patients (10 men, 6 women) with LMG-NTL, 8 patients (4 men, 4 women) with non-LMG-NTL, and 6 patients (4 men, 2 women) with PSL were treated with radiation therapy between January 1975 and December 1994. Four of 8 patients with non-LMG-NTL had tumors of B-cell origin and four had T-cell derived tumors. All 6 patients with PSL had B-cell tumors. They had stage I or II disease. The radiation portal encompassed clinically involved areas with a generous margin. The median dose received was 40 Gy (range, 9-74 Gy) and the median TDF delivered was 63.3 (range, 13.7-103.5). One or two courses of VEPA chemotherapy (same drugs as CHOP, however, drugs doses and treatment schedule are a little different) were administered to the patients with non-LMG-NTL after radiotherapy and the patients with PSL before radiotherapy. In patients with LMG-NTL, between 1975 and 1981 one patient was treated with COPP, one with VEMP after radiotherapy, and two with radiotherapy alone. From 1982 to 1986, all three patients treated for LMG-NTL received VEPA before radiotherapy. Since 1987, of 11 patients treated for LMG-NTL, all except one received two courses of

    Purpose: To determine whether there are any differences in therapeutic response, patterns of systemic recurrence, and prognosis of patients with extranodal natural killer (NK)/T-cell lymphoma, nasal type, by the cyclooxygenase-2 (COX-2) expression. Patients and Methods: Thirty-four patients with Ann Arbor Stage I and II extranodal NK/T-cell lymphoma who underwent chemotherapy or radiotherapy, or both, were retrospectively reviewed. These patients were divided into two groups according to their immunohistochemical staining for COX-2 expressions: a COX-2-negative group (n = 10 patients) and a COX-2-positive group (n = 24 patients). The treatment response, patterns of treatment failure, and survival data for the patients were compared between the COX-2-positive and negative groups. Results: There was no significant difference in the clinical profiles between the COX-2-negative and COX-2-positive groups. All patients (100%) in the COX-2-negative group achieved complete response after initial treatment, whereas only 14 patients (58%) in the COX-2-positive group achieved complete response (p = 0.03). Compared with the patients in the COX-2-negative group, those in the COX-2-positive group had a significantly lower 2-year systemic recurrence-free survival rate (100% for the COX-2-negative group vs. 54% for the COX-2-positive group) (p = 0.02) and a decreased 5-year overall survival rate (70% for the COX-2-negative group vs. 32% for the COX-2-positive group) (p = 0.06). Conclusion: Cyclooxygenase-2 expression can serve as a predictive factor for poor treatment response, higher systemic recurrence, and unfavorable prognosis in patients with extranodal NK/T-cell lymphoma, nasal type

    Background: Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTL) is an aggressive disease with poor prognosis, requiring risk stratification. However, the prognosis of ENKTL is not fully defined and needs supplementation. We hypothesised that fasting blood glucose (FBG) may be a new prognostic factor for ENKTL. Methods: We retrospectively analysed 130 patients newly diagnosed with ENKTL. Results: Both univariate analysis and multivariate analysis revealed that FBG >100 mg dl−1 was associated with a poor outcome. Patients with FBG >100 mg dl−1 at diagnosis had more adverse clinical features, achieved lower complete remission rates (P=0.003) and had worse overall survival (PKPI) scores with different survival outcomes (PKPI.

    To describe the characteristics of CT findings in nasal lymphoma. We retrospectively reviewed CT findings and pathologic findings of eight patients (six males and two females) aged between 24 and 68 years with pathologically-proven nasal lymphoma. We analyzed mass location, laterality, size, margin, mass effect, adjacent bony change and contrast enhancement pattern. All eight cases were non-Hodgkin's lymphoma, intermediate grade, diffuse large cell type. Seven cases were B-cell type and one was T-cell. In all cases, tumors were located in the medial wall of the inferior turbinate. In four cases, they were also found in the anterior ethmoidal sinus, and in one case, in the nasal septum. The mean size of the main mass was 3.3cm. In seven cases, tumors were unilateral (one on the right; six on the left), and in the remaining case, bilateral. In six cases tumor margin was smooth and in two cases focal nodularity was seen. In two cases there was no bony change, and in four, there was mucosal thickening along the nasal septum; in one of these four, minimal bony erosion was also found. In the other two cases, bony destruction was seen, and tumors were very large(7cm in diameter) or bilterally located. In three cases, the nasal septum was displaced by the mass. In all cases with bony change, the nasal septum was involved. All tumors were homogeneously well enhanced after IV contrast administration. The main CT findings of nasal non-Hodgkin's lymphoma were smooth margin, unilateral location (mainly in the medial wall of the inferior turbinate and growing to the medial side without bony destruction) mucosal thickening along the nasal septum and clear homogeneous enhancement after IV contrast administration. These characteristics will help diagnosis, help deter-mine the appropriate region for radiation and other appropriate therapy, and facilitate prognosis in patients with nasal non-Hodgkin's lymphoma.

    Extranodal natural killer (NK)/T-cell lymphoma is a very rare and aggressive disease characterized histopathologically by an Epstein-Barr virus (EBV)-positive atypical lymphoid cytotoxic infiltrate, extensive vascular destruction, and prominent tissue necrosis. It commonly shows cutaneous lesions that primarily or secondarily mimic cellulitis at the primary site. We report on a very rare case of extranodal NK/T-cell lymphoma, nasal type of skin/soft tissue, in a 64-year-old man, and describe the radiological findings. The condition was misdiagnosed as cellulitis of the left arm based on initial noninvasive clinical and radiologic work-up

    We examined malignant lymphomas and polymorphic reticulosis of nasal cavity, nasopharynx, and palate, diagnosed at Korea Cancer Center Hospital from 1987 to 1996. With immunophenotypic study, we reclassified nasal/nasopharyngeal lymphomas into three categories: CD56-positive T/NK lymphoma, CD56-negative lymphoma and B-cell lymphoma. Malignant lymphomas of nasal cavity, nasopharynx and palate were 95 patient, that comprised 11% of the total lymphoma cases, and it was the most common extranodal lymphoma. Twenty-five percent were B-cell lymphomas and 75 % were T/NK lymphomas. According to site, nasal cavity was the most frequent and 91 % of nasal cavity lymphomas were T/NK type. CD56-positive T/NK comprised 82 % of total T/NK lymphomas and CD56-negative cases were 18 %. In 89 % of total T/NK lymphomas, many tumor cells expressed EBER-1 in their nuclei (CD56+ T/NK lymphoma: 97 % of EBV expression, CD56-T-cell lymphoma; 60%). Only one case (5%) of B-cell lymphoma showed EBER-1 positivity in a few cells. CD56+ T/NK lymphomas showed significantly more angiocentricity and severe necrosis than CD56- cases. Although it has no statistical significance, T/NK lymphomas has a tendency to lower survival rates than B-cell lymphomas at 1 year and 2 year. CD56+ T/NK lymphomas has a tendency to lower survival than CD56- T/NK lymphomas (p > 0.05). Our results of this project will serve important basic materials in diagnosing and studying lymphoma.

    Purpose: To evaluate the effectiveness of concurrent chemoradiation therapy (CCRT) with 40 Gy followed by consolidation chemotherapy for localized extranodal natural killer (NK)/T-cell lymphoma (ENKTL), nasal type. Methods and Materials: From August 2004 to August 2012, 62 patients with newly diagnosed stage IE to IIE ENKTL underwent CCRT followed by consolidation chemotherapy. The median RT dose was 40 Gy. Cisplatin, 30 mg/m{sup 2}, was administered weekly during the RT course. Responders to CCRT were encouraged to undergo consolidation chemotherapy. Three different consolidation chemotherapy regimens were used consecutively: VIPD (etoposide, ifosfamide, cisplatin, and dexamethasone); VIDL (etoposide, ifosfamide, and dexamethasone followed by intramuscular injection of L-asparaginase); and MIDLE (methotrexate, etoposide, ifosfamide, mesna, and L-asparaginase). Results: The median follow-up period was 49 months (range 8-112). After completion of CCRT, 56 patients (90.3%) had a complete response, 4 (6.4%) had a partial response, 1 (1.6%) had stable disease, and 1 patient (1.6%) had progressive disease (PD). Consolidation chemotherapy was recommended to 61 patients, after excluding the patient with PD, but was actually delivered to 58. Of these 58 patients, 56 (96.5%) had a complete response and 2 (3.5%) had PD. During the follow-up period, 17 patients (including 3 with PD) experienced progression. The median interval to progression was 11 months (range 1-61). Local failure developed in 6 patients, of whom, 2 had developed progression outside the RT field. For all patients, the 3-year overall survival, progression-free survival, and local control rates were 83.1%, 77.1%, and 92.4%, respectively. Grade ≥3 nonhematologic toxicity developed in only 3 patients (4.8%). Conclusions: Excellent clinical outcomes were achieved using CCRT with 40 Gy followed by consolidation chemotherapy. Additional investigation, however, is warranted to confirm our findings.

    Full Text Available NK/T-cell lymphomas are a group of clonal proliferations of NK- or, rarely, T-cell types and have peculiar clinicopathologic features. Most common site of involvement is the upper aerodigestive tract (nasal cavity, nasopharynx, paranasal sinuses, and palate. Association of autoimmune paraneoplastic disorders with NK/T-cell lymphomas is not well studied. Our patient was diagnosed with NK/T-cell lymphoma stage IV with skin involvement and treated frontline with CHOEP regimen. While he was under treatment, two immune complications presented: anterior uveitis of autoimmune origin refractory to steroids and myositis in lower limbs muscles. Autologous transplantation was rejected due to confirmed early relapse after first-line treatment, and the patient received second-line treatment according to the SMILE scheme, reaching complete response after four cycles. The patient underwent allogeneic transplantation and at the time of manuscript preparation is alive despite multiple complications. The disease should be suspected in patients with rhinitis or recurrent sinusitis, and early biopsy is recommended for all patients to avoid a delay in diagnosis. Our patient also presented symptoms of disease progression after first-line treatment, representing a paraneoplastic process, a very rare phenomenon in T-type lymphomas. This case is novel for the appearance of an inflammatory myositis, a histologically verified paraneoplastic phenomenon that responded to treatment for lymphoma.

    Purpose: This study aims to evaluate the outcome and pattern of failure in a large cohort of patients with Stage I NK/T-cell lymphoma of the upper aerodigestive tract treated with radiotherapy alone. Methods and Materials: The pathological diagnosis was confirmed using standard criteria. All patients were treated with high-dose extended-field radiotherapy alone. The median dose was 50 Gy. The primary tumor was located in the nasal cavity (n = 80), Waldeyer ring (n = 5), or oral cavity (n = 2). Results: The overall response to radiotherapy was achieved in 85 of 87 (97.7%) patients, with a complete response rate of 95.4% and a partial response rate of 2.3%. The 5-year overall survival, progression-free survival, and local control rates for all patients were 80%, 69%, and 93%, respectively. Twenty patients (23%) had disease progression or relapse. Of these, 15 patients (17%) developed systemic extranodal disseminations, whereas only 4 (5%) patients had local relapse and 4 (5%) patients had lymph node relapse. Conclusions: Our study suggests that high-dose extended-field radiotherapy alone is a curative therapy and shows favorable clinical outcome in patients with Stage I disease. With the high possibility of local control and primary failure of systemic dissemination, the integration of optimal radiotherapy with more effective systematic therapy is warranted to bring additional improvement to the outcome for these patients.

    Purpose: To investigate the role of early or up-front radiotherapy (RT), the optimal RT dose required to achieve appropriate treatment outcome and prognostic factors for patients with localized extranodal NK/T-cell lymphoma, nasal-type, in the upper aerodigestive tract. Methods and Materials: Eighty-two patients were reviewed. Eight patients were treated with chemotherapy (CT) alone, 9 patients received RT alone, and 65 patients were given combined modality treatment of CT and RT (CMT). Of those 74 patients receiving RT, 31 patients were given up-front RT, whereas CT was the initial therapy for 43 patients and 41 of those 43 patients received early RT. Results: Five-year overall survival (OS) and disease-free survival (DFS) were 52.3% and 39.2%, respectively. RT was the only independent prognostic factor for both OS and DFS at both the univariate and multivariate level. The 5-year OS and DFS were better in patients receiving ≥54 Gy of RT as compared with that of <54 Gy (5-year OS 75.5% vs. 46.1%, p = 0.019; 5-year DFS 60.3% vs. 33.4%, p = 0.004). Up-front RT presented better survival in Stage I patients when compared with that of initial CT followed by early RT (5-year OS 90.0% vs. 48.9%, p = 0.012; 5-year DFS 78.7% vs. 39.9%, p = 0.021). Conclusion: Early or up-front RT had an essential role in improved OS and DFS in patients with localized extranodal NK/T-cell lymphoma, nasal-type, in the upper aerodigestive tract. The recommended tumor dose was at least 54 Gy. Up-front RT may yield more benefits on survival in patients with Stage I disease

    Extranodal NK/T-cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the U.S. Data on epidemiology, disease presentation, and outcome for European and North American (“Western”) cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the U.S., ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy are consistent across all geographic areas.

We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the USA, ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy is consistent across all geographic areas. Data on epidemiology, disease presentation, and clinical outcomes in mature T cell and NK cell (T/NK cell) neoplasms, including ENKTL-NT, in Europe and North America are very limited. As the classification and diagnostic characterization of the currently recognized T/NK cell lymphoma disease entities continue to evolve, gaps and inconsistencies in data reporting across different studies are being recognized. Despite these limitations, several studies from the USA suggest that the incidence of ENKTL-NT is higher in Asian Pacific Islanders (API) and non-white Hispanics and that outcomes may be worse in non-whites. However, the universal association of ENKTL-NT with Epstein-Barr virus (EBV) across all ethnic groups suggests a common pathogenesis. Given the overlap between the entities included in the category of T/NK cell neoplasms, there is a need to further define

    Extranodal natural killer (NK)/T cell lymphoma, nasal type (ENKTL) is an aggressive non-Hodgkin lymphoma and the majority of ENKTL cases are diagnosed at the localized stage. Radiotherapy in combination with chemotherapy has been used for localized ENKTL, but the optimal combination treatment modality and the best first-line chemotherapy regimen have not been defined. In this retrospective study, 44 patients with newly diagnosed, stages I/II ENKTL were enrolled and received intensity-modulated radiation therapy (IMRT, 50-56 Gy) followed by GDP (gemcitabine, dexamethasone, and cisplatin) chemotherapy. The median number of chemotherapy cycles per patient was 4 (range, 2-6 cycles). At the end of treatment, the overall response rate was 95% (42/44), including 39 patients (89%) who attained complete response. Two patients developed systemic progression after IMRT. With a median follow-up of 37.5 months, the 3-year overall survival (OS) rate and progression-free survival (PFS) rate were 85% (95% CI, 74 to 96%) and 77% (95% CI, 64 to 91%), respectively. Locoregional and systemic failure rates for this treatment were 9% (4/44) and 14% (6/44), respectively. The most common grades 3 to 4 adverse events included leukopenia (37%), neutropenia (34%), and mucositis (25%). No treatment-related deaths were observed. This study suggested high efficacy and low toxicity of IMRT followed by GDP regimen chemotherapy for newly diagnosed stage I/II ENKTL patients. These results require further investigation in prospective trials.

    We retrospectively enrolled 191 nasal-type, extranodal natural killer/T-cell lymphoma (ENKTL) patients newly diagnosed from 2008 to 2016 at the Sichuan Cancer Hospital, in order to evaluate the relationship between disease outcomes, demographic and clinical factors, and red blood cell distribution width (RDW). C-index, fisher's exact test, univariate analysis, and cox regression analysis were applied. The median age of patients was 44 years and 134 (70%) were men. The cutoff of RDW was 46.2 fL determined by Cutoff Finder. Patients with RDW≤46.2 fL had significantly better progression-free survival (PFS) (3-year PFS, 80.4% vs. 63.1%; P =0.01) and overall survival (OS) (3-year OS, 83.2% vs. 65.5%; P =0.004) than those with RDW>46.2 fL. Multivariate analysis demonstrated that elevated RDW is an independent adverse predictor of OS ( P =0.021, HR=2.04). RDW is an independent predictor of survival outcomes in ENKTL, which we found to be superior to both the prognostic index of natural killer lymphoma (PINK) and the Korean Prognostic Index (KPI) in discriminating patients with different outcomes in low-risk and high-risk groups (all P KPI, and PINK showed more powerful prognostic value than corresponding original models. RDW represents an easily available and inexpensive marker for risk stratification in patients with ENKTL treated with radiotherapy-based treatment. Further prospective studies are warranted to confirm the prognostic value of RDW in ENKTL.

    The prognostic significance of ABO blood type for lymphoma is largely unknown. We evaluated the prognostic role of ABO blood type in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). We retrospectively analyzed clinical data of 697 patients with newly diagnosed ENKTL from three cancer centers. The prognostic value of ABO blood type was evaluated using Kaplan-Meier curves and Cox proportional hazard models. The prognostic values of the International Prognostic Index (IPI) and the Korean Prognostic Index (KPI) were also evaluated. Compared with patients with blood type O, those with blood type non-O tended to display elevated baseline serum C-reactive protein levels (P = 0.038), lower rate of complete remission (P = 0.005), shorter progression-free survival (PFS, P 60 years (P KPI in distinguishing between the intermediate-to-low- and high-to-intermediate-risk groups. ABO blood type was an independent predictor of clinical outcome for patients with ENKTL.

    Full Text Available 6q21 genetic deletion has been frequently detected in extranodal NK/T cell lymphoma, nasal type (EN-NK/T-NT, and PRDM1 is considered as candidate gene. However, direct detection of PRDM1 deletion has not been well documented. We investigated genetic alterations of 6q21 and PRDM1 in 43 cases of EN-NK/T-NT and cell lines by FISH. PRDM1 expression was evaluated by immunohistochemistry and Western blot. The correlation between genetic alteration and PRDM1 expression and the significance in clinic-pathologic were analyzed. Heterozygous deletion of 6q21 and/or PRDM1 was observed in 24 of 43 cases (55.81% of EN-NK/T-NT including 16 cases (37.21% for 6q21 deletion and 19 cases (44.19% for PRDM1 deletion. Similarly, heterozygous codeletion of 6q21 and PRDM1 was identified in NK92 and NKL cells. The heterozygous deletion of 6q21 and/or PRDM1 was correlated with PRDM1 expression. However, genetic deletion of 6q21 and/or PRDM1 was not correlated with clinicopathological features of EN-NK/T-NT, while PRDM1 expression showed positive effect on the outcome of patients as those as disease site, B symptom, and clinical stage. Thus, heterozygous deletion of 6q21 and/or PRDM1 was frequently detected in EN-NK/T-NT and correlated with downregulation of PRDM1. But the prognostic role of genetic deletion needs to be further evaluated in larger cohort.

    A 29-year-old stallion presented with bilateral blindness following the chronic purulent nasal drainage. The mass occupied the right caudal nasal cavity and right paranasal sinuses including maxillary, palatine and sphenoidal sinuses, and the right-side turbinal and paranasal septal bones, and cribriform plate of ethmoid bone were destructively replaced by the mass growth. The right optic nerve was invaded and involved by the mass, and the left optic nerve and optic chiasm were compressed by the mass which was extended and invaded the skull base. Histologically, the optic nerves and optic chiasm were degenerated, and the mass was diagnosed as lymphoma which was morphologically and immunohistochemically classified as a diffuse large B-cell lymphoma. Based on these findings, the cause of the blindness in the stallion was concluded to be due to the degeneration of the optic nerves and chiasm associated with lymphoma occurring in the nasal and paranasal cavities. To the best of our knowledge, this is the first report of the equine blindness with optic nerve degeneration accompanied by lymphoma.

    Full Text Available Mature natural killer /T-cell (NK/T-cell lymphomas are a rarely occurring subgroup of Non Hodgkin Lymphomas (NHL. A large majority of NK/T cell lymphomas are extranodal. Nasal type is the most common one. As clinical symptoms are usually nasal obstruction associated with mass lesion and epistaxis in extranodal NK/T cell lymphomas. Their diagnosis is usually delayed when the disease is advanced, it may have serious consequences. The aim of the present article was to present the clinical, radiological and histopathological findings of a 69-year old female patient who had refractory ulcerated wound on left side of nose and followed for soft tissue infection. It was diagnosed with extranodal NK/T cell lymphoma after deep biopsy was obtained from the lesion and to discuss this rare disease in view of literature data.

    C-reactive protein (CRP) is a biomarker of the inflammatory response, and it shows significant prognostic value for several types of solid tumors. The prognostic significance of CRP for lymphoma has not been fully examined. We evaluated the prognostic role of baseline serum CRP levels in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). We retrospectively analyzed 185 patients with newly diagnosed ENKTL. The prognostic value of the serum CRP level was evaluated for the low-CRP group (CRP≤10 mg/L) versus the high-CRP group (CRP>10 mg/L). The prognostic value of the International Prognostic Index (IPI) and the Korean Prognostic Index (KPI) were evaluated and compared with the newly developed prognostic model. Patients in the high-CRP group tended to display increased adverse clinical characteristics, lower rates of complete remission (P60 years, hypoalbuminemia, and elevated lactate dehydrogenase levels were independent adverse predictors of OS. Based on these four independent predictors, we constructed a new prognostic model that identified 4 groups with varying OS: group 1, no adverse factors; group 2, 1 factor; group 3, 2 factors; and group 4, 3 or 4 factors (PKPI in distinguishing between the low- and intermediate-low-risk groups, the intermediate-low- and high-intermediate-risk groups, and the high-intermediate- and high-risk groups. Our results suggest that pretreatment serum CRP levels represent an independent predictor of clinical outcome for patients with ENKTL. The prognostic value of the new prognostic model is superior to both IPI and KPI.

    We conducted a retrospective study of 135 patients of stage IE/IIE extranodal natural killer/T cell lymphoma, nasal type (ENKTL) treated with CHOP as induction chemotherapy to find some valuable prognostic factors and analyze the usefulness of International Prognostic Index (IPI) and Korean Prognostic Index (KPI) in predicting prognosis. Most of the patients were in the low-risk group (IPI score 0-1). Complete remission (CR) after induction chemotherapy was achieved in 31.8 % of the patients, which increased to 69.6 % after radiotherapy. The 2-, 5-, and 10-year overall survival (OS) rates were 60, 48, and 43 %, respectively. Patients with better performance status (ECOG 0-1), normal serum LDH level, without local invasiveness, low KPI scores, and IPI score of 0 had significantly better overall survival (P KPI score systems should be improved further to classify patients into different groups, and should be validated in larger prospective trials. Due to the multi-drug resistance mechanism of ENKTL, CHOP is no longer the state of art and novel drugs should be incorporated into future treatments.

    2014-03-15

    Purpose: To investigate, in a large cohort of patients, the immunophenotypic and clinical differences of nasal and extranasal extranodal nasal-type natural killer/T-cell lymphoma of the upper aerodigestive tract (UADT-NKTCL) and examine the relevance of the immunophenotype on the clinical behavior, prognosis, and treatment. Methods and Materials: A total of 231 patients with UADT-NKTCL were recruited. One hundred eighty-one patients had primary location in the nasal cavity (nasal UADT-NKTCL), and 50 patients had primary extranasal UADT-NKTCL. Results: Patients with extranasal UADT-NKTCL had more adverse clinical features, including advanced-stage disease, regional lymph node involvement, B symptoms, and poor performance status, than patients with nasal UADT-NKTCL. In addition, CD56 and granzyme B were less frequently expressed in extranasal UADT-NKTCL. The 5-year overall survival rate was 74.1% for the entire group and 76.0% for early-stage disease. The 5-year overall survival rate for extranasal UADT-NKTCL was similar or superior to that of nasal UADT-NKTCL for all disease stages (76.9% vs 73.4%, P=.465), stage I disease (75.9% vs 79.2%, P=.786), and stage II disease (83.3% vs 50.3%, P=.018). CD56 expression and a Ki-67 proliferation rate ≥50% predicted poorer survival for extranasal UADT-NKTCL but not for nasal UADT-NKTCL. Conclusions: Patients with nasal and extranasal UADT-NKTCL have significantly different clinical features, immunophenotypes, and prognosis. Extranasal UADT-NKTCL should be considered as a distinct subgroup apart from the most commonly diagnosed prototype of nasal UADT-NKTCL.

    This study aimed to clarify the benefit of radiotherapy (RT) in patients with early-stage extranodal NK/T-cell lymphoma (NKTCL) who achieve a complete response (CR) after asparaginase-containing chemotherapy (CT). Of 240 patients achieved a CR after asparaginase-containing CT, 202 patients received additional RT (CT + RT), and 38 patients did not (CT alone). Compared to CT alone, CT + RT significantly improved overall survival (OS), disease-free survival (DFS) and locoregional control (LRC). The 5-year OS, DFS and LRC rates were 84.9%, 76.2% and 84.9% for CT + RT, compared to 58.9% (P = 0.006), 43.6% (P = 0.001) and 62.1% (P = 0.026) for CT alone. The 5-year cumulative disease recurrence rate was 18.8% for CT + RT compared to 46.9% (P = 0.003) for CT alone. High-dose RT (≥50 Gy) significantly decreased the risk of locoregional recurrence. The 5-year cumulative locoregional failure rate was 35.5% for patients receiving <50 Gy compared to 8.8% for patients receiving ≥50 Gy (P = 0.028). For patients with early-stage NKTCL who achieve a CR after asparaginase-containing CT, omission of RT results in frequent locoregional recurrence and a poor prognosis; RT is essential to improve locoregional control and survival.

    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...

    Neurolymphomatosis refers to lymphoma that has infiltrated the peripheral nervous system and this is the least common clinical presentation of nervous system lymphoma. Most neurolymphomatosis is due to B-cell non-Hodgkin lymphoma, and most patients show lymphomatous infiltration in the meninges and brain parenchyma, in addition to peripheral nervous system involvement. We diagnosed a case of neurolymphomatosis that was confined to the right 4th and 5th lumbar nerve roots without involvement of the meninges or brain parenchyma in a patient with the nasal-type extranodal natural killer/T-cell lymphoma. We made this diagnosis based on the MRI and 18F-FDG PET-CT findings and the clinical manifestations

    2006-01-01

    Objective: To evaluate the effects of nasal non-Hodgkin's lymphoma(N-NHL) treated with chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and autologous peripheral blood stem cell transplantation(APBSCT) combined with total body irradiation(TBI); and to analyze the impact factors of prognosis. Methods: 135 patients were treated between 1980 and 2000. All were confirmed by histopathology as N- NHL, including 122 T cell in origin, 12 B cell and 1 NK cell in origin. The main radiotherapy portal was set in front of the nose with a spade-like protrusion, supplement with a portal next to the ear on one side or both sides. Combined portal in facial cervical area was first used when there was invasion of the oropharynx. The median dose to the nasal cavity was 56.0 Gy with a range of 35.2 to 75.5 Gy, with added 30 Gy to the primary lesion in two patients. Six patients received TBI combined with APBSCT, with 8 Gy in the TBI group. Chemotherapy, given before or during after radiotherapy or alone, consisted of 2-6 cycles of COP, COPP, COMP, CHOP or COBDP. Prognostic factors were analyzed with Cox model. Results: The local control rate was 12%, 69%, 76% and 83% in chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and APBSCT combined with TBI, respectively (P=0.057). The 5-year survival rate was 9%, 52%, 63% and 83%, respectively (P=0.032). Multi- factor analysis showed that tumor extension and treatment methods were the most important prognostic factors be- sides Ann-Arbor stage, but gender, pathology, age and symptoms had little effect on prognosis. Conclusions: Chemotherapy plus radiotherapy group achieves a better survival rate than radiotherapy alone. It is helpful to evaluate prognosis to make more detail subareas on basis of local extensions in Ann Arbor staging system. For some N- NHL patients with good financial condition, APBSCT combined with TBI is a good choice. (authors)

  18. The Four types of Tregs in malignant lymphomas

    Directory of Open Access Journals (Sweden)

    Wang Jing

    2011-12-01

    Full Text Available Abstract Regulatory T cells (Tregs are a specialized subpopulation of CD4+ T cells, which act to suppress the activation of other immune cells. Tregs represent important modulators for the interaction between lymphomas and host microenvironment. Lymphomas are a group of serious and frequently fatal malignant diseases of lymphocytes. Recent studies revealed that some lymphoma T cells might adopt a Treg profile. Assessment of Treg phenotypes and genotypes in patients may offer prediction of outcome in many types of lymphomas including diffuse large B-cell lymphoma, follicular lymphoma, cutaneous T cell lymphoma, and Hodgkin's lymphoma. Based on characterized roles of Tregs in lymphomas, we can categorize the various roles into four groups: (a suppressor Tregs; (b malignant Tregs; (c direct tumor-killing Tregs; and (d incompetent Tregs. The classification into four groups is significant in predicting prognosis and designing Tregs-based immunotherapies for treating lymphomas. In patients with lymphomas where Tregs serve either as suppressor Tregs or malignant Tregs, anti-tumor cytotoxicity is suppressed thus decreased numbers of Tregs are associated with a good prognosis. In contrast, in patients with lymphomas where Tregs serve as tumor-killing Tregs and incompetent Tregs, anti-tumor cytotoxicity is enhanced or anti-autoimmune Tregs activities are weakened thus increased numbers of Tregs are associated with a good prognosis and reduced numbers of Tregs are associated with a poor prognosis. However, the mechanisms underlying the various roles of Tregs in patients with lymphomas remain unknown. Therefore, further research is needed in this regard as well as the utility of Tregs as prognostic factors and therapy strategies in different lymphomas.

    Objective: With the optimal therapy remains unclear for nasal NK/T cell lymphoma, the aim of this study is to analyze the outcome of radiotherapy as primary treatment for localized stage I E and II E diseases. Methods: Between January. 1983 and December 2003, 105 patients with stage I E and II E primary nasal NK/T cell lymphoma were retrospectively reviewed. According to the Ann Arbor Staging System, there were 83 stage I E and 22 stage II E. Stage I E was subdivided into limited stage I E confined to the nasal cavity (37 patients), or extensive stage I E with an extension beyond the nasal cavity (46 patients). Thirty-one patients received radiotherapy alone. Thirty-four patients were treated with radiotherapy followed by 2-4 cycles of chemotherapy. Thirty-seven patients were treated with chemotherapy followed by radiotherapy and 3 with chemotherapy alone. Of 83 patients with stage I E disease, 26 were primarily treated with radiotherapy alone, 30 with. radiotherapy followed by chemotherapy, and 27 with chemotherapy followed by radiotherapy. Results: The five-year overall survival (OS) and progression-free survival rates (PIS) for all patients was 71% and 59%, respectively. The 5-year OS for stage I E and stage II E was 78% and 46% (P<0.01), while the 5-year PFS for stage I E and stage II E was 63% and 40%, respectively (P<0.01). Patients with limited stage I E had a better OS and PFS than those with extensive stage I E, with 5-year OS and PFS of 82% and 80% versus 75% and 45%, respectively. Complete response (CR) was achieved in 91 (87%) patients after radiotherapy and/or chemotherapy. Initial radiotherapy resulted in a superior CR as compared to initial chemotherapy, with 54 of 65 (83%) patients achieving CR with initial radiotherapy, versus only 8 of 40 (20%) with initial chemotherapy. For 102 patients who received radiotherapy with or without chemotherapy, the outcome of primary, treatment with radiotherapy alone was compared to that of CMT. Five-year OS and

    Objective: To evaluate the efficacy of PVD chemo-regimen (Pegaspargase, vincristine and dexamethasone) combined with intensity-modulated radiotherapy (IMRT) for patients with early-stage extranodal nasal NK/T-cell lymphoma (ENKL). Methods: Clinical data of 52 patients with early-stage ENKL were collected during May 2010 and June 2015 in Department of Lymphoma, Cancer Hospital of Guizhou Medical University, and these patients firstly received a concurrent chemoradiotherapy of two-cycle of PVD and IMRT (gross tumor volume primary: 12.6-59.4 Gy) and then 2 to 4 cycles of PVD as subsequent chemotherapy, the efficacy and adverse responses were retrospectively analyzed and observed. Results: Follow-up stopped until December 2015, complete remission was seen in 44 cases (84.6%) and partial remission 7 cases (13.5%), out of 52 cases. A total of 1 case died of progression disease during treatment and within 1 year after treatment, 1 case died of pulmonary infection within 1 week after treatment, 2 cases survived with tumor; so the objective response rate and clinical benefit rate were both 98.1%, 1-year, 2-year and 3-year overall survival rates and progression free survival rates were all 93.6%, 1-year and 2-year disease free survival rates were both 90.3%; the correlation analysis showed that the radiotherapy dose was related to the curative effect ( P PVD regimen and IMRT have a good therapeutic effect and adverse response can be tolerated.

    To distinguish the spiral CT findings of Borrmann type IV adenocarcinoma from those of gastric lymphoma with diffuse gastric wall thickening. We retrospectively reviewed the spiral CT scans of 30 patients with Borrmann type IV adenocarcinoma and nine with gastric lymphoma with diffuse gastric wall thickening. In all patients the respective condition was pathologically confirmed by gastrectomy. CT scanning was performed after peroral administration of 500-700ml of water. A total of 120-140 ml bolus of nonionic contrast material was administered intravenously at a flow rate of 3 ml/sec and two-phase images were obtained at 35-45 sec(early phase) and 180 sec(delayed phase) after the start of bolus injection. Spiral CT was performed with 10mm collimation, 10mm/sec table feed and 10mm reconstruction. We evaluated the degree and homogeneity of enhancement of thickened entire gastric wall, and the enhancement pattern of gastric inner layer, as seen on early-phase CT scans. On early and delayed views, the thickness of gastric wall and the presence of perigastric fat infiltration were determined. The enhancement patterns of gastric inner layer were classified as either continuous or discontinuous thick enhancement, thin enhancement, or nonenhancement. The thickness of gastric wall was 1.2-3.5cm(mean 2.2cm) in cases of adenocarcinoma and 1.2-7.6cm(mean 4cm) in lymphoma. Perigastric fat infiltration was seen in 24 patients with adenocarcinoma(80%) and four with lymphoma(44%). In those with adenocarcinoma, the degree of enhancement of entire gastric wall was hyperdense in fifteen patients(50%) and isointense in eleven (37%). Seven patients with lymphoma(78%)showed hypodensity. In those with adenocarcinoma, continuous thick enhancement of gastric inner layer was seen in 18 patients(60%) and discontinuous thick enhancement in nine(30%). In lymphoma cases, no thick enhancement was observed. Thin enhancement of gastric inner layer was demonstrated in three patients with

    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.

    INTRODUCTION: Patients with Type 1 diabetes mellitus have a high prevalence of coeliac disease, symptoms of which are often mild, atypical, or absent. Untreated coeliac disease is associated with an increased risk of malignancy, particularly of lymphoma. We describe four patients with Type 1 diabetes mellitus and coeliac disease who developed lymphoma. CASE REPORTS: Two patients were male and two female. In three patients, coeliac disease and lymphoma were diagnosed simultaneously. Enteropathy-associated T cell lymphoma occurred in two patients, Hodgkin\\'s disease in one, and B cell lymphoma in one. Response to treatment was in general poor, and three patients died soon after the diagnosis of lymphoma was made. CONCLUSION: As the relative risk of lymphoma is reduced by a gluten-free diet, a high index of suspicion for coeliac disease should exist in all Type 1 diabetic patients with unexplained constitutional or gastrointestinal symptoms.

    Pediatric-type nodal follicular lymphoma (PTNFL) is a variant of follicular lymphoma (FL) characterized by limited-stage presentation and invariably benign behavior despite often high-grade histological appearance. It is important to distinguish PTNFL from typical FL in order to avoid unnecessary treatment; however, this distinction relies solely on clinical and pathological criteria, which may be variably applied. To define the genetic landscape of PTNFL, we performed copy number analysis and exome and/or targeted sequencing of 26 PTNFLs (16 pediatric and 10 adult). The most commonly mutated gene in PTNFL was MAP2K1, encoding MEK1, with a mutation frequency of 43%. All MAP2K1 mutations were activating missense mutations localized to exons 2 and 3, which encode negative regulatory and catalytic domains, respectively. Missense mutations in MAPK1 (2/22) and RRAS (1/22) were identified in cases that lacked MAP2K1 mutations. The second most commonly mutated gene in PTNFL was TNFRSF14, with a mutation frequency of 29%, similar to that seen in limited-stage typical FL (P = .35). PTNFL was otherwise genomically bland and specifically lacked recurrent mutations in epigenetic modifiers (eg, CREBBP, KMT2D). Copy number aberrations affected a mean of only 0.5% of PTNFL genomes, compared with 10% of limited-stage typical FL genomes (P < .02). Importantly, the mutational profiles of PTNFLs in children and adults were highly similar. Together, these findings define PTNFL as a biologically and clinically distinct indolent lymphoma of children and adults characterized by a high prevalence of MAPK pathway mutations and a near absence of mutations in epigenetic modifiers. © 2016 by The American Society of Hematology.

    Epidemiological studies suggest that elevated ambient concentrations of ozone are associated with activation of eosinophils in the nasal airways of atopic and nonatopic children. Mice repeatedly exposed to ozone develop eosinophilic rhinitis and type 2 immune responses. In this study, we determined the role of innate lymphoid cells (ILCs) in the pathogenesis of ozone-induced eosinophilic rhinitis by using lymphoid-sufficient C57BL/6 mice, Rag2(-/-) mice that are devoid of T cells and B cells, and Rag2(-/-)Il2rg(-/-) mice that are depleted of all lymphoid cells including ILCs. The animals were exposed to 0 or 0.8 ppm ozone for 9 consecutive weekdays (4 h/d). Mice were killed 24 hours after exposure, and nasal tissues were selected for histopathology and gene expression analysis. ILC-sufficient C57BL/6 and Rag2(-/-) mice exposed to ozone developed marked eosinophilic rhinitis and epithelial remodeling (e.g., epithelial hyperplasia and mucous cell metaplasia). Chitinase-like proteins and alarmins (IL-33, IL-25, and thymic stromal lymphopoietin) were also increased morphometrically in the nasal epithelium of ozone-exposed C57BL/6 and Rag2(-/-) mice. Ozone exposure elicited increased expression of Il4, Il5, Il13, St2, eotaxin, MCP-2, Gob5, Arg1, Fizz1, and Ym2 mRNA in C57BL/6 and Rag2(-/-) mice. In contrast, ozone-exposed ILC-deficient Rag2(-/-)Il2rg(-/-) mice had no nasal lesions or overexpression of Th2- or ILC2-related transcripts. These results indicate that ozone-induced eosinophilic rhinitis, nasal epithelial remodeling, and type 2 immune activation are dependent on ILCs. To the best of our knowledge, this is the first study to demonstrate that ILCs play an important role in the nasal pathology induced by repeated ozone exposure.

    On the basis of the benefits of frontline radiation in early-stage, extranodal natural killer (NK)/T-cell lymphoma (ENKTL), we conducted the trial of concurrent chemoradiotherapy (CCRT) followed by three cycles of gemcitabine, dexamethasone and cisplatin (GDP). Thirty-two patients with newly diagnosed, stage IE to IIE, nasal ENKTL received CCRT (that is, all patients received intensity-modulated radiotherapy 56 Gy and cisplatin 30 mg/m(2) weekly, 3-5 weeks). Three cycles of GDP (gemcitabine 1000 mg/m(2) intravenously (i.v.) on days 1 and 8, dexamethasone 40 mg orally on days 1-4 and cisplatin 75 mg/m(2) i.v. on day 1 (GDP), every 21 days as an outpatient were scheduled after CCRT. All patients completed CCRT, which resulted in 100% response that included 24 complete responses (CRs) and eight partial responses. The CR rate after CCRT was 75.0% (that is, 24 of 32 responses). Twenty-eight of the 32 patients completed the planned three cycles of GDP, whereas four patients did not because they withdrew (n = 1) or because they had an infection (n = 3). The overall response rate and the CR rate were 90.6% (that is, 29 of 32 responses) and 84.4% (that is, 27 of 32 responses), respectively. Only two patient experienced grade 3 toxicity during CCRT (nausea), whereas 13 of the 30 patients experienced grade 4 neutropenia. The estimated 3-year overall survival and progression-free rates were 87.50% and 84.38%, respectively. In conclusion, CCRT followed by GDP chemotherapy can be a feasible and effective treatment strategy for stage IE to IIE nasal ENKTL.

    This study investigated autophagy in 37 cases of nasopharyngeal lymphomas including 23 nasal natural killer (NK)/T-cell lymphomas (NKTCL), 3 cytotoxic T-cell lymphomas (cytotoxic-TML) and 9 B-cell lymphomas (BML) by means of antigen-retrieval immunohistochemistry of beclin-1, LC3, mitochondria (AE-1) and cathepsin D. Peculiar necrosis was noted in EBV + lymphomas comprising 21 NKTCL, 2 cytotoxic-TML and 1 BML. Lymphomas without peculiar necrosis showed high expression of beclin-1, macrogranular cytoplasmal stain of LC3 with sporadic nuclear stain, a hallmark of autophagic cell death (ACD), some aggregated mitochondria and high expression of cathepsin D, suggesting a state of growth with enhanced autophagy with sporadic ACD. EBV + NKTCL with the peculiar necrosis, showed significantly low level of macrogranular staining of LC3, aggregated mitochondria and low expression of cathepsin D in the cellular areas when degenerative lymphoma cells showed decreased beclin-1, significantly advanced LC3-labeled autophagy, residual aggregated mitochondria and significantly reduced expression of cathepsin D, suggesting advanced autophagy with regional ACD. Consequently it was suggested that enhanced autophagy and reduced expression of lysosomal enzymes induced regional ACD under EBV infection in NKTCL

    To compare computed tomography (CT) and magnetic resonance imaging (MRI) findings between two histological types of nasal hemangiomas (cavernous hemangioma and capillary or lobular capillary hemangioma). CT (n = 20; six pre-contrast; 20 post-enhancement) and MRI (n = 7) images from 23 patients (16 men and seven women; mean age, 43 years; range, 13-73 years) with a pathologically diagnosed nasal cavity hemangioma (17 capillary and lobular capillary hemangiomas and six cavernous hemangiomas) were reviewed, focusing on lesion location, size, origin, contour, enhancement pattern, attenuation or signal intensity (SI), and bony changes. The 17 capillary and lobular hemangiomas averaged 13 mm (range, 4-37 mm) in size, and most (n = 13) were round. Fourteen capillary hemangiomas had marked or moderate early phase enhancement on CT, which dissipated during the delayed phase. Four capillary hemangiomas on MRI showed marked enhancement. Bony changes were usually not seen on CT or MRI (seen on five cases, 29.4%). Half of the lesions (2/4) had low SI on T1-weighted MRI images and heterogeneously high SI with signal voids on T2-weighted images. The six cavernous hemangiomas were larger than the capillary type (mean, 20.5 mm; range, 10-39 mm) and most had lobulating contours (n = 4), with characteristic enhancement patterns (three centripetal and three multifocal nodular), bony remodeling (n = 4, 66.7%), and mild to moderate heterogeneous enhancement during the early and delayed phases. CT and MRI findings are different between the two histological types of nasal hemangiomas, particularly in the enhancement pattern and size, which can assist in preoperative diagnosis and planning of surgical tumor excision.

    Full Text Available We report an extremely rare case of inflammatory myofibroblastic tumor of the posterior edge of the nasal septum. An 11-year-old boy presented with frequent epistaxis and nasal obstruction persisting for one year. Based on the clinical presentation and imaging studies, juvenile angiofibroma was suspected, but angiography suggested the possibility of another type of tumor. Transnasal endoscopic surgery found that the tumor protruded into the nasopharynx from the posterior end of the nasal septum. Histological examination identified spindle cells with immunoreaction for vimentin, smooth muscle actin, and anaplastic lymphoma kinase (ALK, but not for desmin and cytokeratin. This is a report of inflammatory myofibroblastic tumor mimicking juvenile angiofibroma. This case suggests that angiography is helpful in the differential diagnosis of epipharyngeal tumor in adolescence.

    The mechanisms promoting malignant transformation from chronic Helicobacter pylori-gastritis to gastric extranodal marginal zone lymphoma (MALT lymphoma) are insufficiently characterized. This follow-up study aimed to validate candidate microRNAs (miRs) in the process of neoplastic transformation. MicroRNA expression signatures (n=20) were generated for a total of 60 cases of gastric lesions ranging from Wotherspoon 0-5 employing a quantitative real-time polymerase chain reaction (PCR) approach. Morphological and immunohistochemical characterization of the cohort was supplemented by PCR-based immunoglobulin heavy chain recombination studies. Quantitative expression of miR-150, miR-142.3p, miR-375 and miR-494 was significantly de-regulated in samples from MALT lymphoma compared to those from gastritis. The previously reported up-regulation of miR-150 in marginal zone lymphoma of MALT type was verified in an independent cohort of lymphoma samples employing a modified methodology. This further substantiates the role of miR-150 as a potential oncomiR in MALT lymphoma.

    Nasal NK/T-cell lymphoma (NNKTL) is an Epstein-Barr virus (EBV)-associated malignancy and has distinct clinical and histological features. However, its genetic features are hitherto unclear. MicroRNAs (miRNAs) play a crucial role in the pathogenesis of several malignancies via regulating gene expression. In this study, we investigated whether the specific microRNAs were related to the tumor behaviors in NNKTL. MiRNA array and Quantitative RT-PCR analyses revealed that miR-15a was expressed at a much lower level in NNKTL cells (SNK-1, SNK-6, and SNT-8) than in normal peripheral NK cells and EBV-negative NK cell line KHYG-1. Quantitative PCR and western blot analyses showed that the expression of MYB and cyclin D1, which are validated targets of miR-15a, was higher in NNKTL cells. Transfection of NNKTL cells (SNK-6 and SNT-8) with a miR-15a precursor decreased MYB and cyclin D1 levels, thereby blocking G1/S transition and cell proliferation. Knockdown of EBV-encoded latent membrane protein 1 (LMP1) significantly increased miR-15a expression in SNK-6 cells. In NNKTL tissues, we found that reduced miR-15a expression, which correlated with MYB and cyclin D1 expression, was associated with poor prognosis of NNKTL patients. These data suggest that downregulation of miR-15a, possibly due to LMP1, implicates in the pathogenesis of NNKTL by inducing cell proliferation via MYB and cyclin D1. Thus, miR-15a could be a potential target for antitumor therapy and a prognostic predictor for NNKTL. Copyright © 2013 Wiley Periodicals, Inc.

    Primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL LT) accounts for approximately 20% of all primary cutaneous B-cell lymphomas and tends to present as infiltrated nodules, tumors, and plaques on the legs in the elderly. Unlike other primary cutaneous large B-cell lymphomas, it has a poor prognosis and tends to require treatment with systemic chemotherapy. We present the case of an 82-year-old patient with a 1-year history of nodules and plaques on her right leg. Biopsy led to a diagnosis of PCLBCL LT and the lesions resolved without treatment within 1 month of the first visit. This is an atypical course of PCLBCL LT and we believe that it is the first such case to be reported in the literature. Copyright © 2012 Elsevier España, S.L. and AEDV. All rights reserved.

    Objective: Although radiation therapy is frequently used in the treatment of ocular adnexal lymphoma, it is uncertain whether it is curative, or whether it simply provides local control in a systemic disease. Extranodal marginal zone (mucosa-associated lymphoid tissue [MALT] type) lymphoma, a recently described type of low-grade lymphoma, is often localized at diagnosis and may therefore potentially be curable with local therapy. We analyzed the pathologic and clinical features of 165 cases of ocular adnexal lymphoma to determine the proportion that were MALT lymphomas, and to compare the frequency of primary versus secondary involvement, the frequency of localized disease, and the probability for local and distant recurrences after radiation therapy in MALT lymphoma relative to other lymphomas. Methods: Clinical and pathologic (morphologic and immunophenotypic) findings were reviewed in 165 cases of ocular adnexal lymphoma diagnosed between 1974 and 1994. The lymphomas were classified according to the recently described Revised European-American Lymphoma Classification Scheme which newly incorporated the diagnostic category of extranodal marginal zone (MALT) lymphoma. Staging information was available in 73 primary cases. Radiation was given as either photons (for intraorbital disease) or electrons (for superficial disease). Photon treatment primarily consisted of a wedged pair of anterior plus anterior-oblique fields to a median dose of 39.6 Gy (range 19.8 - 46 Gy) at 1.8 Gy per fraction. Electron treatment consisted of an en face field to a median dose of 30 Gy (range 25.6 - 40 Gy) at 2.5 Gy per fraction. Survival data were analyzed by the Kaplan-Meier actuarial method. P-values for differences between frequencies of lymphoma types and stages were calculated by chi square. Results: In 133 patients with no known prior history of lymphoma (primary cases), MALT lymphoma accounted for 55%, while other cases were follicle center lymphoma (FCL) (22%), low grade

    This study aimed to investigate the prevalence of human papilloma virus (HPV), herpes simplex virus-1/-2 (HSV-1/-2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpes virus-6/-7 (HHV-6/-7) in 23 human nasal polyps by applying PCR. Two types of control tissues were used: adjacent inferior/middle turbinates from the patients and inferior/middle turbinates from 13 patients undergoing nasal corrective surgery. EBV was the virus most frequently detected (35%), followed by HPV (13%), HSV-1 (9%), and CMV (4%). The CMV-positive polyp was simultaneously positive for HSV-1. HPV was also detected in the adjacent turbinates (4%) and the adjacent middle turbinate (4%) of one of the HPV-positive patients. EBV, HSV, and CMV were not detected in the adjacent turbinates of the EBV-, HSV- or CMV-positive patients. All mucosae were negative for the VZV, HHV-6, and HHV-7. This is the first study to deal with the involvement of a comparable group of viruses in human nasal polyposis. The findings support the theory that the presence of viral EBV markedly influences the pathogenesis of these benign nasal tumors. The low incidence of HPV detected confirms the hypothesis that HPV is correlated with infectious mucosal lesions to a lesser extent than it is with proliferative lesions, such as inverted papilloma. The low incidence of HSV-1 and CMV confirms that these two herpes viruses may play a minor role in the development of nasal polyposis. Double infection with HSV-1 and CMV may also play a minor, though causative, role in nasal polyp development. VZV and HHV-6/-7 do not appear to be involved in the pathogenesis of these mucosal lesions.

    To investigate the curative effects of oral and nasal administration of chicken type II collagen (CII) on adjuvant arthritis (AA) in rats with meloxicam-induced intestinal lesions. AA model in Sprague-Dawley (SD) rats with or without intestinal lesions induced by meloxicam was established and those rats were divided randomly into six groups which included AA model, AA model+meloxicam, AA model+oral CII, AA model+nasal CII, AA model+ meloxicam+oral C II and AA model+meloxicam+nasal CII (n = 12). Rats was treated with meloxicam intragastrically for 7 d from d 14 after immunization with complete Freund's adjuvant (CFA), and then treated with chicken CII intragastrically or nasally for 7 d. Histological changes of right hind knees were examined. Hind paw secondary swelling and intestinal lesions were evaluated. Synoviocyte proliferation was measured by 3-(4,5-dimethylthiazol-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide (MTT) method. Activities of myeloperoxidase (MPO) and diamine oxidase (DAO) from supernatants of intestinal homogenates were assayed by spectrophotometric analysis. Intragastrical administration of meloxicam (1.5 mg/kg) induced multiple intestinal lesions in AA rats. There was a significant decrease of intestinal DAO activities in AA+meloxicam group (P<0.01) and AA model group (P<0.01) compared with normal group. DAO activities of intestinal homogenates in AA+meloxicam group were significantly less than those in AA rats (P<0.01). There was a significant increase of intestinal MPO activities in AA+meloxicam group compared with normal control (P<0.01). Oral or nasal administration of CII (20 microg/kg) could suppress the secondary hind paw swelling(P<0.05 for oral CII; P<0.01 for nasal CII), synoviocyte proliferation (P<0.01) and histopathological degradation in AA rats, but they had no significant effects on DAO and MPO changes. However, oral administration of CII (20 microg/kg) showed the limited efficacy on arthritis in AA+meloxicam model and the

    Purpose: This study aimed to determine the pathways of primary tumor invasion (PTI) and regional lymph node (LN) spread based on magnetic resonance imaging (MRI) in early-stage nasal NK/T-cell lymphoma (NKTCL), to improve clinical target volume (CTV) delineation and evaluate the prognostic value of locoregional extension patterns. Methods and Materials: A total of 105 patients with newly diagnosed early-stage nasal NKTCL who underwent pretreatment MRI were retrospectively reviewed. All patients received radiation therapy with or without chemotherapy. Results: The incidences of PTI and regional LN involvement were 64.7% and 25.7%, respectively. Based on the incidence of PTI, involved sites surrounding the nasal cavity were classified into 3 risk subgroups: high-risk (>20%), intermediate-risk (5%-20%), and low-risk (<5%). The most frequently involved site was the nasopharynx (35.2%), followed by the maxillary (21.9%) and ethmoid (21.9%) sinuses. Local disease and regional LN spread followed an orderly pattern without LN skipping. The retropharyngeal nodes (RPNs) were most frequently involved (19.0%), followed by level II (11.4%). The 5-year overall survival (OS), progression-free survival (PFS), and locoregional control (LRC) rates for all patients were 72.8%, 65.2%, and 90.0%, respectively. The presence of PTI and regional LN involvement based on MRI significantly and negatively affected PFS and OS. Conclusions: Early-stage nasal NKTCL presents with a high incidence of PTI but a relatively low incidence of regional LN spread. Locoregional spread followed an orderly pattern, and PTI and regional LN spread are powerful prognostic factors for poorer survival outcomes. CTV reduction may be feasible for selected patients.

    Full Text Available Nasal gliomas are rare, benign, congenital tumors that are thought to be result of abnormality in embryonic development. Three types of clinical presentations have been recognized; extranasal, intranasal and combined. Clinically, these masses are non-pulsatile, gray or purple lesions that obstruct the nasal cavity and cause deformity extranasaly. Histologically, they are made up of astrocytic cells, fibrous and vascular connective tissue that is covered with nasal respiratory mucosa. Treatment of the nasal glioma requires a multidisciplinary approach including an radiologist, neurosurgeon and otorhinolaryngologist. Radiological investigation should be performed to describe intracranial extension. In this case, a 2 years old boy with nasal mass that was diagnosed as nasal glioma is reported. .

    Full Text Available We report a case of histologically confirmed primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT that subsequently underwent spontaneous regression in the absence of systemic treatment. The case showed an atypical lymphoid infiltrate that was CD20+ and MUM-1+ and CD10–. A subsequent biopsy of the spontaneously regressed lesion showed fibrosis associated with a lymphocytic infiltrate comprising reactive T cells. PCDLBCL-LT is a cutaneous B-cell lymphoma with a poor prognosis, which is usually treated with chemotherapy. We describe a case of clinical and histologic spontaneous regression in a patient with PCDLBCL-LT who had a negative systemic workup but a recurrence over a year after his initial presentation.

    In the European Organization for Research and Treatment of Cancer (EORTC) classification 2 types of primary cutaneous large B-cell lymphoma (PCLBCL) are distinguished: primary cutaneous follicle center cell lymphomas (PCFCCL) and PCLBCL of the leg (PCLBCL-leg). Distinction between both groups is considered important because of differences in prognosis (5-year survival > 95% and 52%, respectively) and the first choice of treatment (radiotherapy or systemic chemotherapy, respectively), but is not generally accepted. To establish a molecular basis for this subdivision in the EORTC classification, we investigated the gene expression profiles of 21 PCLBCLs by oligonucleotide microarray analysis. Hierarchical clustering based on a B-cell signature (7450 genes) classified PCLBCL into 2 distinct subgroups consisting of, respectively, 8 PCFCCLs and 13 PCLBCLsleg. PCLBCLs-leg showed increased expression of genes associated with cell proliferation; the proto-oncogenes Pim-1, Pim-2, and c-Myc; and the transcription factors Mum1/IRF4 and Oct-2. In the group of PCFCCL high expression of SPINK2 was observed. Further analysis suggested that PCFCCLs and PCLBCLs-leg have expression profiles similar to that of germinal center B-cell-like and activated B-cell-like diffuse large B-cell lymphoma, respectively. The results of this study suggest that different pathogenetic mechanisms are involved in the development of PCFCCLs and PCLBCLs-leg and provide molecular support for the subdivision used in the EORTC classification.

The incidence of CLL and RCC occurring in the same patient is higher than that expected in the general population. Various explicative hypotheses of this concurrence include treatment-related development of a second malignancy, immunomodulatory mechanisms, viral aetiology, cytokine (interleukin 6 release from a tumor, and common genetic mutations. Further investigations are warranted.

    Lymphomas represent the fifth most frequent cancer in Lebanon. However, little is known concerning epidemiologic characteristics and distribution of lymphoid neoplasms according to the 2008 WHO classification. We conducted a retrospective study of lymphoma cases diagnosed from 2008 till 2012 at Hotel-Dieu de France University Hospital. A total of 502 new cases of lymphoma were diagnosed at our institution during a five year period: 119 cases (24%) were Hodgkin lymphomas (HL) and 383 cases (76%) were non-Hodgkin lymphomas (NHL). HLs were equally distributed in both sexes with a mean age at diagnosis of 30 years. Among NHL, 87% (332 cases) were B cell lymphomas, 9% (34 cases) were T cell lymphomas and 4%(17 cases) were classified as precursor lymphoid neoplasms. Among B cell lymphomas, 44% (147 cases) were diffuse large B cell lymphomas (DLBCL), 20% (65 cases) follicular lymphomas and 8% (27 cases) mantle cell lymphomas. DLBCL were equally distributed in both sexes with a mean age of 58 years. Follicular lymphomas were characterized by a male predominance (57%) and a mean age of 60 years. Mantle cell lymphomas showed a pronounced male predominance (85%) with a mean age of 60 years in men and 70 years in women. Some 72% of patients having T cell lymphomas were men, with a mean age of 57 years in men and 45 years in women, while 65% of patients having precursor lymphoid neoplasms were women with a mean age of 22 years in women and 30 years in men. The lymphoma subtype distribution in Lebanon is unique when compared to other countries from around the world. In fact, Hodgkin and follicular lymphomas are more frequent than in most Far Eastern, European and American countries, while T-cell lymphomas and DLBCL are less frequent.

    To evaluate the frequently of low attenuation area in enhanced CT scans of non-Hodgkin lymphoma(NHL) and to find out if there is any pertinent relationship between this and the histopathologic classification. The authors reviewed CT scans in the newly-diagnosed 53 patients with NHL. We defined the low attenuation area as the one with CT attenuation value lower than that of the muscle, surrounding lesion, or other lymph nodes after contrast enhancement. NHL with the low attenuation areas were correlated with the histopathologic findings according to the classification based on the Working Formulation and the frequency of the lesion was evaluated. Of the 53 patients, the low attenuation area was found in 13 patients (25%) at CT. The histopathologic classification could be made in 12 patients, among whom one patient was classified as low-grade, six as intermediate-grade, and five as high-grade. Concerning the specific cell typing, the diffuse large cell type was most common in intermediate-grade NHL seen in five patients and the large cell, immunoblastic type was most common in high-grade NHL seen in three patients. The authors concluded that the low attenuation area within lymphoma is not an infrequent finding at CT, and there was no statistically significant correlation between this finding and the prognostic grading of the Working Formulation.

    Full Text Available Screening for coeliac disease is recommended for children from certain risk groups, with implications for diagnostic procedures and dietetic management. The risk of a malignant complication in untreated coeliac disease is not considered high in children. We present the case of a girl with type I diabetes who developed weight loss, fatigue, and inguinal lymphadenopathy. Four years before, when she was asymptomatic, a screening coeliac tTG test was positive, but gluten was not eliminated from her diet. Based on clinical examination, a duodenal biopsy, and an inguinal lymph node biopsy were performed, which confirmed both coeliac disease and an anaplastic large-cell lymphoma. HLA-typing demonstrated that she was homozygous for HLA-DQ8, which is associated with higher risk for celiac disease, more severe gluten sensitivity, and diabetes susceptibility. She responded well to chemotherapy and has been in remission for over 4 years. She remains on a gluten-free diet. This is the first case reporting the association of coeliac disease, type I diabetes, and anaplastic large-cell lymphoma in childhood. The case highlights the malignancy risk in a genetically predisposed individual, and the possible role of a perpetuated immunologic response by prolonged gluten exposure.

    Objective: In recent years, a large proportion of non-Hodgkin's lymphomas of the stomach are recognized as low grade tumors of the mucosa associated lymphoid tissue (MALT) type. Since the MALT morphological subtype has only gained acceptance as a malignant lymphoma after the establishment of the Working Formulation, there is limited information about its natural history, disease pattern, and longterm treatment outcome. This study is an analysis of these parameters in patients with primary MALT lymphoma of the stomach. Materials and Methods: Consecutive patients with primary gastric MALT lymphoma who received definitive treatment at the Massachusetts General Hospital between (4(78)) and (2(95)) were included in the study. The diagnosis was pathologically verified in all cases. Clinical staging studies included chest X-ray +/- chest CT, abdomino-pelvic CT or bipedal lymphangiogram, barium swallow, and bone marrow biopsy. Treatment strategies included combinations of partial or total gastrectomy, radiation (RT) and chemotherapy (chemo). RT was given via multifield technique, with 10-25MV photons, to doses of 36-50.4 Gy (1.1-1.8 Gy per fraction, 5 days a week). Survival analyses were performed by the Kaplan-Meier actuarial method. Results: There were twenty-two patients between the ages of 45 - 93 years, with a mean follow-up of 67 months. Ten were male and 12 female. The most frequent presenting symptoms were epigastric pain (77%), dyspepsia (65%), and melena (41%). The mean duration of symptoms was 27 months. Eighteen cases were clinical stage (cs)I, two csII, one csIII, and one csIV. The treatment approaches were: 1) csI:6 gastrectomy alone, 7 gastrectomy and RT, 1 gastrectomy and chemo, 2 RT alone, 1 chemo and RT, 1 no therapy; 2) csII: 2 gastrectomy and RT; 3) csIII: 1 gastrectomy and chemo; 4) csIV: 1 chemo and RT. Among 16 gastrectomy specimens, multifocal gastric involvement was evident in 50%. The most frequently involved sites were the body (63%) and antrum

    MYC-rearranged (MYC-R) lymphomas other than Burkitt lymphoma (BL) are very aggressive, with poor prognosis when treated with standard regimens. We aimed to study the characteristics and outcome of a series of MYC-R lymphomas comparing the treatment results between R-CHOP based and a specific intensive regimen for BL (BURKIMAB). Retrospective study of patients diagnosed with MYC-R. Translocations of MYC, BCL2 and BCL6 were evaluated by fluorescent in situ hybridization. Patients were treated with either, R-CHOP based immunochemotherapy or the Burkitt type regimen, BURKIMAB. Thirty-four MYC-R lymphoma cases were studied: 21 treated with R-CHOP and 13 treated with BURKIMAB. There were no differences in CR rate; 45% (9/20) for R-CHOP and 42% (5/12) for BURKIMAB (P=.99). Although overall survival (OS) and progression free survival (PFS) of BURKIMAB-treated patients were better than those of R-CHOP-treated (3y-OS: 46 vs. 24%; 3y-PFS: 46 vs. 10%), the differences were not statistically significant. MYC-R lymphomas show poor outcomes even when treated with intensive immunochemotherapy for BL. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative data. Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a balanced text; (2) a set of nasal sentences and four sets of oral sentences and (3) repetitions of each of 12 syllable types (8 oral and 4 nasal). The last two sets of material corpus were based on an adaptation of the Simplified Nasometric Assessment Procedures Test (SNAP test) test ( MacKay and Kummer, 1994 ) in Greek, called the G-SNAP test. Eighty monolingual healthy young adult speakers of Greek, 40 males (mean age = 21 years) and 40 females (mean age = 20.5 years), with normal hearing and speech characteristics and unremarkable history were included in the study. The Nasometer (model 6200-3) was used to derive nasalance scores. Mean normative nasalance for spoken Greek was 25.50%, based on the G-oronasal text (with 8.6% nasals). Nasalance scores did not differ significantly with respect to gender. Finally, spoken Greek consistently yielded lower nasalance scores than other languages examined in past work. The aforementioned normative data on nasalance of young adult speakers of Greek are valid across gender and have direct clinical utility as they provide valuable reference information for the diagnosis and management of Greek adults with resonance disorders caused by velar dysfunction.

    Intravascular lymphoma (IVL) is a rare extra nodal subtype (usually of B-cell origin) presenting with infiltration of large neoplastic lymphocytes into lumina of blood vessels, leading to vascular occlusion. The early diagnosis is very crucial, however it is usually diagnosed postmortem investigation in most of the cases. A 56-year-old female presented with elevated creatinine level, and anasarca-type edema that superimposed with hard, indurated, erythematous plaques extending to inguinal region, abdomen, anterior aspect of chest, and face. B-cell IVL was confirmed with skin biopsy. The patient had some degree of clinical improvement following chemotherapy. B-cell IVL presenting with anasarca edema was not previously reported in the literature. Even if its rarity, IVL should be considered in the differential diagnosis of renal failure with anasarca edema.

    Extranodal natural killer (NK)/T-cell lymphoma, nasal type, is an uncommon lymphoma associated with the Epstein-Barr virus (EBV). It most commonly involves the nasal cavity and upper respiratory tract. Primary pulmonary NK/T cell lymphoma is extremely rare. If a patient with a NK or T-cell tumor has an unusual reaction to treatment or an unusual prognosis, it is wise to differentiate NK from T-cell tumors. The clinicopathologic characteristics, immunophenotype, EBV in situ hybridization, and T cell receptor (TCR) gene rearrangement of primary pulmonary NK cell lymphoma from a 73-year-old Chinese woman were investigated and the clonal status was determined using female X-chromosomal inactivation mosaicism and polymorphisms at the phosphoglycerate kinase (PGK) gene. The lesion showed the typical histopathologic characteristics and immunohistochemical features of NK/T cell lymphoma. However, the sample was negative for TCR gene rearrangement. A clonality assay demonstrated that the lesion was monoclonal. It is concluded that this is the first recorded case of genuine primary pulmonary NK cell lymphoma. The purpose of the present work is to recommend that pathologists carefully investigate the whole lesion to reduce the likelihood that primary pulmonary NK cell lymphoma will be misdiagnosed as an infectious lesion. In addition, TCR gene rearrangement and clonal analysis, which is based on female X-chromosomal inactivation mosaicism and polymorphisms at PGK and androgen receptor (AR) loci, were found to play important roles in differentiating NK cell lymphoma from T cell lymphoma.

    Full Text Available The DNA damage response (DDR induces the expression of type I interferons (IFNs, but the underlying mechanisms are poorly understood. Here, we show the presence of cytosolic DNA in different mouse and human tumor cells. Treatment of cells with genotoxic agents increased the levels of cytosolic DNA in a DDR-dependent manner. Cloning of cytosolic DNA molecules from mouse lymphoma cells suggests that cytosolic DNA is derived from unique genomic loci and has the potential to form non-B DNA structures, including R-loops. Overexpression of Rnaseh1, which resolves R-loops, reduced the levels of cytosolic DNA, type I Ifn transcripts, and type I IFN-dependent rejection of lymphoma cells. Live-cell imaging showed a dynamic contact of cytosolic DNA with mitochondria, an important organelle for innate immune recognition of cytosolic nucleotides. In summary, we found that cytosolic DNA is present in many tumor cells and contributes to the immunogenicity of tumor cells.

    Twenty cases of nasal bone fractures were evaluated as to the types of fractures based upon HRCT findings. Conventional X-Ray films for nasal bones were analyzed and compared with HRCT findings. Nasal bone fractures were classified into lateral and frontal fractures. HRCT images were evaluated in three planes including upper, middle and lower portions of the nasal bone. Fractures favored males of teens. Lateral fracture gave rise to the fractures of the nasal bone opposite to the external force, loosening of the ipsilateral nasomaxillary sutures and fractures of the frontal process of the maxilla. Conventional X-Ray films were reevaluated after HRCT evaluation and indications of nasal bone fractures were determined. In addition to the discontinuity of the nasal dorsum, fracture lines parallel to and beneath the nasal dorsum and indistinct fracture lines along the nasomaxillary sutures are the indication of nasal bone fractures by conventional X-Ray films.

    Objective: To determine the clinical, histological, and immuno phenotypic characteristics of mycosis fungoides type cutaneous T-cell lymphoma. Design: Descriptive study. Place and Duration of Study: This study was conducted from January 2000 to December 2004 at the Department of Dermatology, Military Hospital and the Department of Dermatopathology, Armed Forces Institute of Pathology, Rawalpindi. Materials and Methods: The medical case records of patients with mycosis fungoides diagnosed during the period of study were surveyed. Data was collected pertaining to patients' characteristics, clinical descriptions, histopathological features, immuno phenotypic analysis and stage of disease at the time of diagnosis. Results: A total of 33 cases of mycosis fungoides were diagnosed between the years 2000 and 2004. There were 24 male and 9 female patients with male to female ratio of 2.6:1 The age ranged from 24 to 68 years and the duration of disease prior to diagnosis varied between 2 to 36 months. The number of skin biopsies performed for definite diagnosis ranged from 01 to 5. The various clinical presentations recorded in these patients were hypo pigmented patches in 7 (21.3%), infiltrated papules and plaques in 6 (18.2%), erythroderma in 5 (15.2%), psoriasiform lesions in 3 (9%), and nodular lesions in 3 (9%) patients. There were 2 (6%) cases respectively of noduloulcerative, ichthyosiform and poikilodermatous lesions, and 1 (3%) case each of follicular, morphoea-like and purpuric skin lesions. The predominant histological features were lymphocytic infiltrate in the upper dermis, epidermotropism, haloed lymphocytes in epidermis, Pautrier's micro abscesses, and interface dermatitis. The immunohistochemical studies (n=12) showed predominantly T helper cell immuno phenotype (CD3+, CD45RO+) in 11 (92%) cases and T suppressor cell immuno phenotype (CD3+, CD8+) in 1 (8%) patient. Conclusion: The mycosis fungoides type cutaneous T-cell lymphoma has a wide clinico

    This article is aimed to compare the dosimetric differences between volumetric modulated arc therapy (VMAT) and intensity-modulated radiotherapy (IMRT) for Stage I-II nasal natural killer/T-cell lymphoma (NNKTL). Ten patients with Stage I-II NNKTL treated with IMRT were replanned with VMAT (2 arcs). The prescribed dose of the planning target volume (PTV) was 50 Gy in 25 fractions. The VMAT plans with the Anisotropic Analytical Algorithm (Version 8.6.15) were based on an Eclipse treatment planning system; the monitor units (MUs) and treatment time (T) were scored to measure the expected treatment efficiency. All the 10 patients under the study were subject to comparisons regarding the quality of target coverage, the efficiency of delivery, and the exposure of normal adjacent organs at risk (OARs). The study shows that VMAT was associated with a better conformal index (CI) and homogeneity index (HI) (both p < 0.05) but slightly higher dose to OARs than IMRT. The MUs with VMAT (650.80 ± 24.59) were fewer than with IMRT (1300.10 ± 57.12) (relative reduction of 49.94%, p = 0.00) when using 2-Gy dose fractions. The treatment time with VMAT (3.20 ± 0.02 minutes) was shorter than with IMRT (7.38 ± 0.18 minutes) (relative reduction of 56.64%, p = 0.00). We found that VMAT and IMRT both provide satisfactory target dosimetric coverage and OARs sparing clinically. Likely to deliver a bit higher dose to OARs, VMAT in comparison with IMRT, is still a better choice for treatment of patients with Stage I-II NNKTL, thanks to better dose distribution, fewer MUs, and shorter delivery time.

    We describe an outbreak of bullous impetigo (BI) that occurred in a maternity unit and show phenotypic and genotypic properties and relatedness of isolated Staphylococcus aureus strains. Clinical material was obtained from 11 affected neonates. Additionally, nasal swabs from 67 healthy care workers (HCWs) as well as 107 environmental swabs were investigated. All isolates were screened for exfoliative toxin genes (eta, etb), antibiotic susceptibility and phage typed. Chromosomal DNA was genotyped by MLVF method and PCR/RFLP of coagulase gene were tested. Affected neonates were infected by two clusters of eta-positive S. aureus of phage type 3C/71: (1) MLVF type A isolates resistant only to penicillin, and (2) MLVF type B isolates resistant to penicillin and erythromycin/clindamycin. All isolates were susceptible to methicillin. We found 19 of 67 HCWs to be S. aureus nasal carriers. Two nasal isolates from HCWs were related to the outbreak on the basis of phage typing, PCR detection of eta/etb genes, antibiotyping and genotyping. Additionally, environmental swabs from the maternity unit revealed a 3C/71 S. aureus in the mattress of a baby bed. This is the first documented case of an outbreak of BI caused by phage type 3C/71 eta-positive strain of S. aureus.

Moreover, 34 patients with pure lymphnoditis were served as the control group. FCM and full-automatic speed scattering turbidimetry were used to detect T lymphocyte subsets proportion, IgG, IgA, IgM, C3, and C4 in the three groups. Results: The comparison of CD3+, CD4+, CD8+, NK cell proportion, and CD4+/CD8+ among the three groups was significantly different. When compared with the control group, CD3+, CD4+, CD8+, NK cell proportion, and CD4+/CD8+ in the extranodular group and nodular group were significantly reduced; moreover, CD3+, CD4+, CD8+, and CD4+/ CD8+ in the extranodular group were significantly lower than those in the nodular group, while NK cell in the extranodular group was significantly higher than that in the nodular group. The comparison of IgG, IgA, and C3 levels among the three groups was statistically significant. When compared with the control group, IgG and IgA levels in the extranodular group and nodular group were significantly elevated, while C3 level was significantly reduced, and the comparison between the extranodular group and nodular group between the two groups was statistically significant. IgM level in the extranodular group and nodular group was elevated, C4 level was reduced, but the comparison with the control group was not statistically significant. Spearman correlation analysis showed that CD3+ and CD4+ were significantly correlated with IgA, IgG, and C3. Conclusions: With the increasing of severity degree of lymphoma, the immunological level is reduced, while CD3+ and CD4+ are significantly correlated with Ig

    Full Text Available Intraocular lymphoma (IOL is a rare lymphocytic malignancy which contains two main distinct forms. Primary intraocular lymphoma (PIOL is mainly a sub-type of primary central nervous system lymphoma (PCNSL. Alternatively, IOL can originate from outside the central nervous system (CNS by metastasizing to the eye. These tumors are known as secondary intraocular lymphoma (SIOL. The IOL can arise in the retina, uvea, vitreous, Bruch’s membrane and optic nerve. There are predominantly of B-cell origin; however there are also rare T-cell variants. Diagnosis remains challenging for ophthalmologists and pathologists, due to its ability to masquerade as noninfectious or infectious uveitis, white dot syndromes, or occasionally as other metastatic cancers. Laboratory tests include flow cytometry, immunocytochemistry, interleukin detection (IL-10: IL-6, ratio >1, and polymerase chain reaction (PCR amplification. Methotrexate-based systemic chemotherapy with external beam radiotherapy and intravitreal chemotherapy with methotrexate are useful for controlling the disease, but the prognosis remains poor. Therefore, it is important to make an early diagnose and treatment. This review is focused on the clinical manifestations, diagnosis, treatment and prognosis of the IOL.

    To evaluate the CT findings of malignant nasal cavity tumors. Retrospective analysis was performed on 20 patients with pathologically-proven malignant nasal cavity tumors. Using CT, we analysed their location, extent of bone destruction and of involvement of adjacent structures, and enhancing pattern. A total of 20 cases included nine squamous cell carcinomas, three olfactory neuroblastomas, three lymphomas, two polymorphic reticulosis, one adenoid cystic carcinoma, one undifferentiated carcinoma and one metastasis from renal cell carcinoma. All cases except one adenoid cystic carcinoma and one squamous cell carcinoma revealed bone destruction or erosion. Aggressive bone destruction and irregular enhancement were seen in eight cases of squamous cell carcinoma, seven cases of which showed involvement of the adjacent paranasal sinuses, nasopharynx, and orbit. Olfactory neuroblastomas were centered in the superior nasal cavity and the adjacent ethmoid sinus, and erosion or destruction of the cribriform plate had occurred. Lymphomas showed bilateral involvement, with uniform contrast enhancement. Polymorphic reticuloses showed perforation or erosion of the nasal septum, with bilateral involvement of the nasal cavity. The location, presence of bone destruction, involvement of adjacent structures, and enhancement pattern of tumor on CT can be helpful for the differential diagnosis of malignant nasal cavity tumors

    2016-01-01

    Extranodal natural killer/T-cell lymphoma, nasal type (NKTL) is a rare but highly aggressive Epstein-Barr virus-related malignancy, which mainly occurs in nasopharyngeal and nasal/paranasal areas. In addition to its high prevalence in Asian, Central American and South American populations, its incidence rate has been gradually increasing in Western countries. The current mainstay of treatment is a combination of multiple chemotherapies and irradiation. Although chemoradiotherapy can cure NKTL, it often causes severe and fatal adverse events. Because a growing body of evidence suggests that immunotherapy is effective against hematological malignancies, this treatment could provide an alternative to chemoradiotherapy for treatment of NKTL. In this review, we focus on how recent findings could be used to develop efficient immunotherapies against NKTL.

Determination of canine lymphoma immunophenotype is useful for accurate prognosis and further therapy. In the suggested study, we performed an immunohistochemical evaluation of some cases with canine lymphoma diagnosed in the Department of Pathology (Faculty of Veterinary Medicine, Cluj-Napoca, Romania, in order to characterize them. The investigation included 39 dogs diagnosed with different anatomical forms of lymphoma, following necropsy analysis or assessment of biopsies. The diagnosis of lymphoma was confirmed by necropsy and histopathology (Hematoxylin-eosin stain examinations. The collected specimens were analyzed by immunohistochemistry technique (automatic method using the following antibodies: CD3, CD20, CD21 and CD79a. The analyzed neoplasms were characterized as follows: about 64.10% of cases were diagnosed as B-cell lymphomas, 33.34% of cases as T-cell lymphomas, whereas 2.56% of cases were null cell type lymphomas (neither B nor T.

    CD1d-restricted NKT cells represent a unique lineage of immunoregulatory T cells that are divided into two groups, type I and type II, based on their TCR usage. Because there are no specific tools to identify type II NKT cells, little is known about their developmental requirements and functional regulation. In our previous study, we showed that signaling lymphocytic activation molecule-associated protein (SAP) is essential for the development of type II NKT cells. Here, using a type II NKT cell TCR transgenic mouse model (24αβTg), we demonstrated that CD1d-expressing hematopoietic cells but not thymic epithelial cells meditate efficient selection of type II NKT cells. Further, we showed that SAP regulates type II NKT cell development by controlling Egr2 and PLZF expression. SAP-deficient 24αβ transgenic T cells (24αβ T cells) exhibited an immature phenotype with reduced Th2 cytokine-producing capacity and diminished cytotoxicity to CD1d-expressing lymphoma cells. The impaired IL-4 production by SAP-deficient 24αβ T cells was associated with reduced IRF4 and GATA-3 induction following TCR stimulation. Collectively, these data suggest that SAP is critical for regulating type II NKT cell responses. Aberrant responses of these T cells may contribute to the immune dysregulation observed in X-linked lymphoproliferative disease caused by mutations in SAP. PMID:25236978

    Peripheral T- or natural killer (NK)-cell lymphomas are rare and difficult-to-recognize diseases. It remains arduous to distinguish between NK cell- and cytotoxic T-lymphocyte-derived lymphomas through routine histological evaluation. To clarify the cells of origin, we focused on NK-cell receptors and examined the expression using immunohistochemistry in 22 cases with T- and NK-cell neoplasms comprising angioimmunoblastic T-cell lymphoma, anaplastic lymphoma kinase (ALK)-positive and -negative anaplastic large-cell lymphomas, extranodal NK/T-cell lymphoma, nasal type, monomorphic epitheliotropic intestinal T-cell lymphoma, aggressive NK-cell leukemia, and other peripheral T-cell lymphomas. Inhibitory receptor leukocyte immunoglobulin-like receptor subfamily B member 1 (LILRB1) was detected in 14 (64%) cases, whereas activating receptors DNAM1, NKp46, and NKG2D were expressed in 7 (32%), 9 (41%), and 5 (23%) cases, respectively. Although LILRB1 was detected regardless of the disease entity, the activating NK-cell receptors were expressed predominantly in TIA-1-positive neoplasms (DNAM1, 49%; NKp46, 69%; and NKG2D, 38%). In addition, NKp46 and NKG2D were detected only in NK-cell neoplasms and cytotoxic T-lymphocyte-derived lymphomas including monomorphic epitheliotropic intestinal T-cell lymphoma. One Epstein-Barr virus-harboring cytotoxic T-lymphocyte-derived lymphoma mimicking extranodal NK/T-cell lymphoma, nasal type lacked these NK-cell receptors, indicating different cell origin from NK and innate-like T cells. Furthermore, NKG2D expression showed a negative impact on survival among the 22 examined cases, which mainly received the standard chemotherapy regimen (log-rank test, P = .024).

    Our patient was an 86-year-old man who had worked as a lathe operator for 40 years. He had no history of tuberculosis, pyothorax, or autoimmune disease. He had not been exposed to asbestos. He was asymptomatic, but an imaging study showed gradually increasing pleural plaques. A biopsy specimen of a pleural lesion showed sclerosis of the pleura and diffuse infiltration of small- to medium-sized B lymphocytes. Polymerase chain reaction-based analysis detected monoclonal rearrangement of immunoglobulin heavy-chain genes. Histologic diagnosis was extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma). The lymphoma was negative for Epstein-Barr virus. We report a rare case of a metal worker with MALT lymphoma arising in the pleura with pleural fibrous plaques. It is speculated that MALT lymphoma might develop in the background of pneumoconiosis. Inflammatory and/or immunologic reactions to metal particles might contribute to the oncogenesis of this tumor. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available The aim of this study was to determine the nasal parameters in the population of central Serbia and to compare them with those determined in earlier studies in different populations. The research was conducted on 496 randomly selected persons (262 males and 234 females, aged 18-65 years. The measured parameters were nasal height and nasal breadth and the standard spreading caliper with scale was used for measurements. There were significant differences in the nasal parameters between male and female subjects. The nasal breadth was 34.72 mm in females, and in the male population it was 36.7 mm. The mean values of nasal height were 52.6 mm and 54.32 mm in females and males, respectively. The nasal index in females and males was 66.01 and 67.56, respectively, and the mean value of the nasal index of all respondents was 66.78. After conducting the research it was concluded that the dominant nasal type in the population of the central part of Serbia is leptorrhine. The present study showed the existence of sexual dimorphism in nasal morphology. The data obtained in our study may be useful in anthropological and forensic research, as well as in cosmetic planning and reconstructive surgery.

    Full Text Available Jiu-Cong Zhang, Yong Wang, Xiu-Feng Wang, Fang-Xin Zhang Department of Gastroenterology, Lanzhou General Hospital of Lanzhou Military Command, Lanzhou, People’s Republic of China Abstract: Enteropathy-associated T-cell lymphoma (EATL is a rare gastrointestinal non-Hodgkin’s lymphoma, originating from intraepithelial T-lymphocyte, which is specifically associated with celiac disease. EATL most commonly presents in the sixth and seventh decades of life. We report a unique case of type I EATL in the colon with liver metastasis, which was presented with nonspecific radiological findings and at a very young age (29 years old compared with previously published data. We suggest that EATL should be regarded as part of differential diagnosis in any patient presenting with abdominal pain, diarrhea, weight loss, and malabsorption because delay in treatment can result in an irreversible clinical outcome.

    Full Text Available Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT is one of the well-recognized extranodal lymphomas commonly addicted to the B-cell receptor-MYD88 superpathway. We aimed to describe the genomic changes in a patient who progressed through treatment with ibrutinib, a Bruton’s tyrosine kinase (BTK inhibitor. An 80-year-old woman presented with multiply relapsed PCDLBCL-LT after multiple lines of chemoimmunotherapy and radiotherapy. Pre-treatment testing of the localized cutaneous tumor lesion on a lymphoid amplicon panel demonstrated an MYD88 p.L265P mutation. Ibrutinib therapy was subsequently commenced, resulting in complete resolution of the skin disease. Despite an ongoing skin response, the patient developed progressive nodal disease at two months. Genomic analysis of the cutaneous tumor sample at baseline was compared to that of the inguinal lymph node upon progression, and revealed the acquisition of multiple genomic changes. These included several aberrations expected to bypass BTK inhibition, including two CARD11-activating mutations, and a deleterious mutation in the nuclear factor kappa B (NF-κB negative regulator, NFKBIE. In addition, an IgH-IRF8 translocation was detected (which brings the IRF8 transcription factor under control of the immunoglobulin heavy chain locus, representing a third plausible mechanism contributing to ibrutinib resistance. Several copy-number changes occurred in both samples, including an amplification of 18q, which encodes the anti-apoptotic protein BCL2. We describe the first case of novel genomic changes of PCDLBCL-LT that occurred while on ibrutinib, providing important mechanistic insights into both pathogenesis and drug resistance.

    CD1d-restricted NKT cells represent a unique lineage of immunoregulatory T cells that are divided into two groups, type I and type II, based on their TCR usage. Because there are no specific tools to identify type II NKT cells, little is known about their developmental requirements and functional regulation. In our previous study, we showed that signaling lymphocytic activation molecule associated protein (SAP) is essential for the development of type II NKT cells. Here, using a type II NKT-cell TCR transgenic mouse model, we demonstrated that CD1d-expressing hematopoietic cells, but not thymic epithelial cells, meditate efficient selection of type II NKT cells. Furthermore, we showed that SAP regulates type II NKT-cell development by controlling early growth response 2 protein and promyelocytic leukemia zinc finger expression. SAP-deficient 24αβ transgenic T cells (24αβ T cells) exhibited an immature phenotype with reduced Th2 cytokine-producing capacity and diminished cytotoxicity to CD1d-expressing lymphoma cells. The impaired IL-4 production by SAP-deficient 24αβ T cells was associated with reduced IFN regulatory factor 4 and GATA-3 induction following TCR stimulation. Collectively, these data suggest that SAP is critical for regulating type II NKT cell responses. Aberrant responses of these T cells may contribute to the immune dysregulation observed in X-linked lymphoproliferative disease caused by mutations in SAP. © 2014 WILEY-VCH Verlag GmbH & Co.

    The authors present a case of nasal chondromesenchymal hamartoma (NCMH) in an 8-year-old boy with a 4-month history of frontal headache and no symptoms of nasal obstruction, rhinorrhoea or postnasal drip. An ENT examination as well as ophthalmology assessment presented normal results. CT scan showed a lesion involving the sphenoid and ethmoid sinuses. The patient had an endoscopic resection of the lesion that was confirmed histologically to be a NCMH. Though NCMH is known to present usually in infants with obstructing nasal mass, an unusual presentation of a patient with throbbing headache without any nasal symptoms is reported here.

    2015-12-01

    Full Text Available Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT is a rare diffuse large B-cell lymphoma confined to the skin of the legs. The typical presentation is characterized by solitary or multiple growing plaques, usually confined to one leg. We report a case of PCDLBCL-LT of activated B-cell subtype characterized by multiple local relapses in the legs, initially, and systemic relapses about seven years after the diagnosis. Local relapses were sensitive to radiation therapy. Cutaneous and systemic relapses responded well to immunomodulatory therapy with lenalidomide followed by Bruton’s tyrosine kinase inhibition with ibrutinib. Ibrutinib is the only treatment that resulted in long-lasting complete remission. Lenalidomide and especially ibrutinib appear to have a significant activity against this lymphoma and should be incorporated in the treatment of this resistant and aggressive lymphoma. To our knowledge, this is the first case of PCDLBCL-LT reported in the literature exhibiting a complete response to ibrutinib.

    The case is reported of a 55-year-old man with diffuse malignant lymphoma type B associated with transient optic chiasm infiltration and visual disturbances but with persistent hypopituitarism, hyperprolactinaemia and diabetes insipidus. The patient was administered chemotherapy and radiotherapy. Repeated MR and CT scans showed optic chiasm infiltration, which disappeared in the course of the chemotherapy but then recurred, changed its appearance and finally disappeared again. In the meantime visual disturbances occurred and disappeared during the therapy. Hypopituitarism, diabetes insipidus and hyperprolactinaemia were diagnosed and replacement therapy was administered. Later on abdominal pain occurred, and a CT scan revealed bilateral kidney masses and enlarged retroperitoneal lymph nodes. These were diffuse malignant lymphoma with regional lymphonodulitis in histology. Finally, hydrothorax and hydroretroperitoneum were diagnosed. The patient died as a result of systemic complications of the disease. The length of survival time documented following the hypothalamochiasmatic infiltration and diagnosis of lymphoma makes the case an unusual one for patients with CNS lymphoma. Hormonal disturbances accompanying the suprasellar region infiltration are very important from the practical point of view. (author)

    Objective Several types of nasal packs are used postoperatively in septoplasty. In this study, we compared two commonly used nasal packing materials, the intranasal septal splint with airway and Merocel tampon, in terms of pain, bleeding, nasal obstruction, eating difficulties, discomfort in sleep, and pain and bleeding during removal of packing in the early period. Methods The study group included 60 patients undergoing septoplasty. Patients were divided into two groups (n=30 in each group). An intranasal splint with airway was used for the patients in the first group after septoplasty, while Merocel nasal packing was used for the second group. Patients were investigated in terms of seven different factors - pain, bleeding while the tampon was in place, nasal obstruction, eating difficulties, night sleep, pain during removal of the nasal packing, and bleeding after removal of packing. Results There was no statistically significant difference between the groups in terms of pain 24 hours after operation (p=0.05), while visual analog scale (VAS) scores for nasal obstruction, night sleep, eating difficulties, and pain during packing removal were lower in the nasal splint group with a statistically significant difference (p<0.05). There was no statistically significant difference between the groups in terms of postoperative bleeding (p=0.23). Significantly less bleeding occurred during removal of the packing in the nasal splint group (p<0.05). Conclusion Our study indicates that the nasal splint was more comfortable and effective in terms of causing lesser bleeding and pain during removal of packing. PMID:29392071

    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.

  7. A Case Report of Nongerminal Center B-Cell Type Diffuse Large B-Cell Lymphoma Treated to Complete Response with Rituximab and Ibrutinib

    Full Text Available Diffuse large B-cell lymphoma (DLBCL is a molecularly heterogeneous disease consisting of different subtypes with varying clinical behaviors. For example, the activated B-cell-like (ABC type of DLBCL has lower cure rates with traditional chemotherapy regimens. The molecular pathway promoting tumorigenic growth of the ABC type includes a dependence on intracellular signaling by Bruton’s agammaglobulinemia tyrosine kinase (BTK. This specific pathway has led to the investigation of the utility of ibrutinib in treatment of this type of lymphoma at relapse or in combination with standard chemotherapy. In elderly patients stricken with this disease, standard combination chemotherapy can pose significant toxicity. Some reduced intensity regimens have activity but significantly less favorable long-term outcomes and still pose significant toxicity to elderly patients. In the following case, we demonstrate induction of complete response in an elderly patient with significant comorbidities with nongerminal center B-cell type (NGCB DLBCL treated with rituximab, ibrutinib, and prednisone. Toxicity included atrial fibrillation that ultimately led to heart failure as well as sepsis which ultimately led to the patient’s demise. Despite this fact, the response to treatment appeared durable. This case illustrates the utility and limitations of molecularly targeted therapies to treat aggressive lymphoma in frail elderly patients.

    Background Over one hundred different pharmaceutical dosage forms have been recorded in literatures of Traditional Persian Medicine among which nasal forms are considerable. Objectives This study designed to derive the most often applied nasal dosage forms together with those brief clinical administrations. Materials and Methods In the current study remaining pharmaceutical manuscripts of Persia during 9th to 18th century AD have been studied and different dosage forms related to nasal application of herbal medicines and their therapeutic effects were derived. Results By searching through pharmaceutical manuscripts of medieval Persia, different nasal dosage forms involving eleven types related to three main groups are found. These types could be derived from powder, solution or liquid and gaseous forms. Gaseous form were classified into fumigation (Bakhoor), vapor bath (Enkebab), inhalation (Lakhlakheh), aroma agents (Ghalieh) and olfaction or smell (Shomoom). Nasal solutions were as drops (Ghatoor), nasal snuffing drops (Saoot) and liquid snuff formulations (Noshoogh). Powders were as nasal insufflation or snorting agents (Nofookh) and errhine or sternutator medicine (Otoos). Nasal forms were not applied only for local purposes. Rather systemic disorders and specially CNS complications were said to be a target for these dosage forms. Discussion While this novel type of drug delivery is known as a suitable substitute for oral and parenteral administration, it was well accepted and extensively mentioned in Persian medical and pharmaceutical manuscripts and other traditional systems of medicine as well. Accordingly, medieval pharmaceutical standpoints on nasal dosage forms could still be an interesting subject of study. Therefore, the current work can briefly show the pharmaceutical knowledge on nasal formulations in medieval Persia and clarify a part of history of traditional Persian pharmacy. PMID:24624204

    Full Text Available Nasal lobular capillary hemangioma is a rare benign tumor of the paranasal sinuses. This lesion is believed to grow rapidly in size over time. The exact etiopathogenesis is still a dilemma. We discuss a case of nasal lobular capillary hemangioma presenting with a history of epistaxis. Contrast enhanced computed tomography of paranasal sinuses revealed an intensely enhancing soft-tissue mass in the left nasal cavity and left middle and inferior meati with no obvious bony remodeling or destruction. We present imaging and pathologic features of nasal lobular capillary hemangioma and differentiate it from other entities like nasal angiofibroma.

    2017-04-01

    Full Text Available Abstract Extranodal natural killer (NK/T-cell lymphoma is an aggressive malignancy of putative NK-cell origin, with a minority deriving from the T-cell lineage. Pathologically, the malignancy occurs in two forms, extranodal NK/T-cell lymphoma, nasal type; and aggressive NK-cell leukaemia. Lymphoma occur most commonly (80% in the nose and upper aerodigestive tract, less commonly (20% in non-nasal areas (skin, gastrointestinal tract, testis, salivary gland, and rarely as disseminated disease with a leukemic phase. Genetic analysis showed mutations of genes involved in the JAK/STAT pathway, RNA assembly, epigenetic regulation, and tumor suppression. In initial clinical evaluation, positron emission tomography computed tomography, and quantification of plasma EBV DNA are mandatory as they are useful for response monitoring and prognostication. In stage I/II diseases, combined chemotherapy and radiotherapy (sequentially or concurrently is the best approach. Conventional anthracycline-containing regimens are ineffective and should be replaced by non-anthracycline-containing regimens, preferably including L-asparaginase. Radiotherapy alone is associated with high systemic relapse rates and should be avoided. In stage III/IV diseases, non-anthracycline-regimens-containing L-asparaginase are the standard. In relapsed/refractory cases, blockade of the programmed death protein 1 has recently shown promising results with high response rates. In the era of effective non-anthracycline-containing regimens, autologous haematopoietic stem cell transplantation (HSCT has not been shown to be beneficial. However, allogeneic HSCT may be considered for high-risk or advanced-stage patients in remission or relapsed/refractory patients responding to salvage therapy. Prognostic models taking into account presentation, interim, and end-of-treatment parameters are useful in triaging patients to different treatment strategies.

    A fracture of nasal bones is becoming a very common injury due to the increasingly greater number of car accidents and aggravated criminal situation. A total of 500 cases of nasal fracture associated with external deformities were included in the present study. The following kinds of deformities were identified: unilateral retraction, lateral displacement of the entire dorsum of the nose, and depressed comminuted fracture. Rhinoscopy revealed in addition such abnormalities associated with septal fracture as submucous hemorrhage, pathological mobility of the pyramid, deflection of the nasal septum at an acute angle. All in all, four types of nasal septum fractures were distinguished depending on the shape and localization of the fracture line. Two of them resulted in marked impairment of nasal breathing while two others required surgical intervention in the acute period after the injury.

    Directory of Open Access Journals (Sweden)

    Luisa Lorenzi

    Full Text Available Hermansky Pudlak type 2 syndrome (HPS2 is a rare autosomal recessive primary immune deficiency caused by mutations on β3A gene (AP3B1 gene. The defect results in the impairment of the adaptor protein 3 (AP-3 complex, responsible for protein sorting to secretory lysosomes leading to oculo-cutaneous albinism, bleeding disorders and immunodeficiency. We have studied peripheral blood and lymph node biopsies from two siblings affected by HPS2. Lymph node histology showed a nodular lymphocyte predominance type Hodgkin lymphoma (NLPHL in both HPS2 siblings. By immunohistochemistry, CD8 T-cells from HPS2 NLPHL contained an increased amount of perforin (Prf + suggesting a defect in the release of this granules-associated protein. By analyzing peripheral blood immune cells we found a significant reduction of circulating NKT cells and of CD56(brightCD16(- Natural Killer (NK cells subset. Functionally, NK cells were defective in their cytotoxic activity against tumor cell lines including Hodgkin Lymphoma as well as in IFN-γ production. This defect was associated with increased baseline level of CD107a and CD63 at the surface level of unstimulated and IL-2-activated NK cells. In summary, these results suggest that a combined and profound defect of innate and adaptive effector cells might explain the susceptibility to infections and lymphoma in these HPS2 patients.

    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)

    Full Text Available Background. Lymphoma of the urinary bladder (LUB is rare. Aims. To review the literature on LUB. Methods. Various internet databases were used. Results. LUB can be either primary or secondary. The tumour has female predominance; most cases occur in middle-age women. Secondary LUB occurs in 10% to 25% of leukemias/lymphomas and in advanced-stage systemic lymphoma. Less than 100 cases have been reported. MALT typically affects adults older than 60 years; 75% are female. Diffuse large B-cell lymphoma is also common and may arise from transformation of MALT. LUB presents with haematuria, dysuria, urinary frequency, nocturia, and abdominal or back pain. Macroscopic examination of LUBs show large discrete tumours centred in the dome or lateral walls of the bladder. Positive staining of LUB varies by the subtype of lymphoma; B-cell lymphomas are CD20 positive. MALT lymphoma is positively stained for CD20, CD19, and FMC7 and negatively stained for CD5, CD10, and CD11c. LUB stains negatively with Pan-keratin, vimentin, CK20, and CK7. MALT lymphoma exhibits t(11; 18(q21: 21. Radiotherapy is an effective treatment for the MALT type of LUB with no recurrence. Conclusions. LUB is diagnosed by its characteristic morphology and immunohistochemical characteristics. Radiotherapy is a useful treatment.

  1. FDG-PET in lymphomas

    Lymphomas are a heterogeneous group of neoplasms in which two major subtypes are distinguished, Hodgkin's disease (HD) and non-Hodgkin's lymphomas (NHL). The incidence of lymphomas is about 20 per 100000 inhabitants (Jemal et al 2002) and 7-8 times higher than that of HD. Since NHL has a worse prognosis, the death rates of NHL are 14 times higher than those for HD. Lymphomas account for about 4 % of all cancer incidences. In USA, lymphomas are the fifth most frequent cancer type diagnosed and the third most frequent form of cancer death (Jemal et al 2002). Concerning HD, there is a preponderance for males with a gender ratio of 1.33 for incidence and 1.12 for mortality. For NHL incidences and mortality rates of genders are almost equal. HL comprises different subtypes among which nodular sclerosis is the most frequent one (60-70 %). Other histopathologic subtypes are those of mixed cellularity, lymphocyte reach and lymphocyte depleted characteristics. The most frequent subgroup of NHL are B-cell lymphomas (80-90 % of all NHL). Two thirds of this subgroup are diffuse large B-cell lymphomas, one third follicular lymphomas. Other (less frequent) subtypes are mantle cell, peripheral T-cell, anaplastic large-cell-lymphomas etc. For NHL increasing incidence has been observed in the last decades. Within 15 years the incidence increased by 50 % in the USA (Jemal et al 2002). Etiology of lymphomas is still unknown. In a certain proportion of NHL viral causes are assumed. Diagnosis is based on histology (needle biopsy) with consecutive sub typing. Prognosis depends on stage, expansion state, histology and proliferation rates. (author)

    Intravaginal (ivag) or intranasal (i.n.) immunization of C57BL/6J (B6) mice with a thymidine kinase-deficient strain (tk-) of herpes simplex virus type 2 (HSV-2) resulted in comparable protection of the genital epithelium and sensory ganglia against HSV-2 challenge. In contrast, protection of these sites was much reduced in i.n.-immunized compared to ivag-immunized B cell-deficient μMT mice. Fewer HSV-specific T cells were detected in the genital epithelium of i.n.-immunized compared to ivag-immunized μMT mice after HSV-2 challenge. Passive transfer of HSV-specific serum to immune μMT mice restored protection of these sites against HSV-2 challenge. These results suggest that protection of genital and neuronal sites may be conferred by i.n. immunization but may be more dependent on antibody-dependent mechanisms than the protection resulting from genital immunization. These results have implications for immunization strategies to elicit high levels of cell-mediated protection of the genital tract and sensory ganglia

    Lymphomas are a heterogeneous group of neoplasms with distinct morphologic, immunologic, and cytogenetic characteristics. Overlapping morphologic and immunophenotypic features often makes accurate diagnosis difficult. Cytogenetics helps simplify the diagnostic complexities presented in transforming and progressive lymphoid malignancies. Genetic studies using technical advances such as fluorescence in situ hybridization and the newer approaches of array comparative genomic hybridization and gene expression profiling play a critical and often defining role in the diagnosis, progression, prognosis, and therapeutic stratification. This article reviews characteristic cytogenetic abnormalities in specific subtypes of lymphomas at diagnosis, disease progression, and prognosis.

    2003-06-01

    Introduction: To evaluate the computed tomographic (CT) findings of primary thyroid lymphoma. Methods and material: The clinicopathological data and CT images of nine patients with primary thyroid lymphoma were retrospectively reviewed. The CT appearances were classified into three types: type 1, a solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, a homogeneously enlarged both thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: All patients had a rapidly enlarging thyroid mass and coexistent Hashimoto's thyroiditis. One patient showed type 1 pattern, three type 2, and five type 3. Six patients had homogeneous tumor isoattenuating to surrounding muscles. The tumors had a strong tendency to compress normal remnant thyroid and the surrounding structure without invasion. Conclusion: Primary thyroid lymphoma should be included in the differential diagnosis when old female had a homogeneous thyroidal mass isoattenuating to muscles, which does not invade surrounding structures.

    2009-01-01

    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.)

    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.)

    Recent evidence strongly suggests that the microbiota of the nasal cavity plays a crucial role in determining the reaction patterns of the mucosal and systemic immune system. However, little is known about the normal microbiota of the nasal cavity. The purpose of this study was to determine...... the microbiota in different parts of the nasal cavity and to develop and evaluate methods for this purpose. Samples were collected from 10 healthy adults by nasal washes and by swabbing of the mucosa through a sterile introduction device. Both methods gave results that were quantitatively and qualitatively...... reproducible, and revealed significant differences in the density of the nasal microbiota between individuals. The study revealed absence of gram-negative bacteria that are regular members of the commensal microbiota of the pharynx. Likewise, viridans type streptococci were sparsely represented. The nasal...

    Directory of Open Access Journals (Sweden)

    Yukiko Nishi

    2017-06-01

    Full Text Available Primary extranodal malignant lymphoma of the thyroid is a rare entity composed of mostly neoplastic transformation of germinal center-like B cells (GCB or memory B cells. Other B-cell-type malignancies arising primarily in the thyroid have rarely been described. Immunohistochemical examination of autopsied primary malignant lymphoma of the thyroid in an 83-year-old Japanese female revealed the presence of a non-GCB subtype of diffuse large B-cell lymphoma (DLBCL without the typical codon 206 or 265 missense mutation of MYD88. The lack of the highly oncogenic MYD88 gene mutation, frequently observed in DLBCL of the activated B-cell (ABC subtype, and the detection of an extremely aggressive yet local clinical phenotype demonstrated that the present case was an exceptional entity of the type3 (non-GCB and non-ABC subtype.

  3. Radiotherapy of adult nodal non Hodgkin's lymphoma

    International Nuclear Information System (INIS)

    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.

    2016-11-04

    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.

    2003-01-01

    Diabetes mellitus is the most common endocrinologic disease all over the world. 150 million people suffer from this disease, in Poland about 2 million. The disease on the basis of the onset and pathophysiology may be divided into type I and type II. Pathophysiologic changes include diabetic microangiopathy, macroangiopathy and neuropathy. The most common presentations in head and neck are otitis externa, hypoacusis, vertigo, disequilibrium, xerostomia, dysphagia, fungal and recurrent infections. The changes in nasal mucosa are not very well known. Only few papers concerned the problem. The main complaints of patients regarding the nose are xeromycteria, hyposmia and various degree of decreased patency of the nose. Chronic atrophic rhinitis, septal perforation, ulceration of nasal mucosa, alar necrosis, symptoms of staphylococcal or fungal infection can be found during otolaryngologic examination. The treatment in this group of patients should consist of systemic therapy of diabetes mellitus and on the other hand focal therapy with the use of a solution to moisten the nasal mucosa.

    2013-01-01

    Full Text Available Introduction. Plasmacytomas are malignant tumors characterized by abnormal monoclonal proliferation of plasma cells. They originate in either bone - solitary osseous plasmacytoma, or in soft tissue - extramedullary plasmacytoma (EMP. EMP represents less than 1% of all head and neck malignancies. Case report. We presented a case of EMP of the nasal septum in a 44-year-old male who had progressive difficulty in breathing through the nose and frequent heavy epistaxis on the right side. Nasal endoscopy showed dark red, soft, polypoid tumor in the last third of the right nasal cavity arising from the nasal septum. The biopsy showed that it was plasmacytoma. Bence Jones protein in the urine, serum electrophoresis, bone marrow biopsy, skeletal survey and other screening tests failed to detect multiple myeloma. This confirmed the diagnosis of EMP. The mass was completely removed via an endoscopic approach, and then, 4 week later, radiotherapy was conducted with a radiation dose of 50 Gray. No recurrence was noted in a 3-year follow- up period. Conclusion. EMP of the nasal cavity, being rare and having long natural history, represents a diagnostic and therapeutic challenge for any ear, nose and throat surgeon. Depending on the resectability of the lesion, a combined therapy is the accepted treatment.

    2011-01-01

    Full Text Available Introduction: The primary nasal lymphoma is an uncommon extranodal tumor and represents 0.44% of all Extranodal lymphomas in this region. The primary nasal lymphoma derives from the T-lineage in nearly 75% of the cases. Objective: To describe a case of nasosinusal lymphoma of T Natural Killer cells, attended in the Clinical Hospital of the Federal University of Goiás. Case Report: 48-year-old female patient with diffuse tumefaction in the left hemiface of firm-elastic consistency and painful upon digital compression. Face sinuses tomography identified a total maxillary veiling to the left and some posterior ethmoidal cells. With the diagnostic hypothesis of a tumor affection, we opted for the surgical removal via a transmaxillary approach and the material was sent for biopsy. The histopathological exam diagnosed a highly necrotic tumor of angiocentric pattern, polymorphic and atypical lymphoid population (T /NK Lymphoma; with the prognosis, the patient was submitted to chemical therapy with total regression of the facial edema. Final Comments: The otorhinolaryngologist must be attentive as regards the existence of lymphomas among the nasosinusal diseases, because the early diagnosis improves the survival as it prevents metastases, growth and local destruction.

    2011-02-01

    Nasal reconstruction after resection for cutaneous malignancies poses a unique challenge to facial plastic surgeons. The nose, a unique 3-D structure, not only must remain functional but also be aesthetically pleasing to patients. A complete understanding of all the layers of the nose and knowledge of available cartilage grafting material is necessary. Autogenous material, namely septal, auricular, and costal cartilage, is the most favored material in a free cartilage graft or a composite cartilage graft. All types of material have advantages and disadvantages that should guide the most appropriate selection to maximize the functional and cosmetic outcomes for patients. Copyright © 2011 Elsevier Inc.

    Objective was to present a histopathologic and immunohistochemical analysis of primary gastric lymphomas that was reclassified according to the new World Health Organization classification of lymphoid neoplasms. We reviewed the morphological and immunohistochemical features of 28 patients with gastric lymphomas, diagnosed in the Department of pathology at the University Hospital of Tishreen University, Lattakia, Syria, during the period 1994-2003. Specimens were obtained from endoscopic and surgical biopsies. The immunohistochemical study was performed to analyze the immunophenotype of these lymphomas. Patients were aged 17-71 years. There was a slight predominance of females (male to female ratio, 13:15). Seventeen of the patients had tumors mainly located in the gastric antrum. Histologically, the most common lymphoma was of mucosa-associated lymphoid tissue (MALT) type (20 patients), also with diffuse large B-cell lymphoma (7 patients) and anaplastic large cell lymphoma (one patient). Our study demonstrates the different patterns of gastric lymphomas in Lattakia, Syria during a 10-year period in 28 Syrian patients, and reveals that the most primary gastric lymphomas are B-cell MALT lymphomas.

    Nine cases of primary intracranial malignant lymphoma, which accounts for 3.3 % of all intracranial tumors seen in the authors' institution, were studied in terms of diagnostic computed tomographic (CT) features, the tumors' histologic appearance, treatment, post-treatment blood immunologic and cerebrospinal fluid (CSF) characteristics, and outcome. The patients were seven males and two females aged 42 to 67 years. Their chief signs and symptoms on admission were intracranial hypertension, focal signs, and disturbance of consciousness. CT, which proved the most useful preoperative diagnostic technique, demonstrated multiple lesions in seven cases and, in all cases, regions of isodensity or slight high density that were enhanced by contrast medium. According to the patterns of enhancement, the tumors were classed as diffuse (three cases) or nodular (six cases). The former is considered typical of malignant lymphoma, whereas the latter type was sometimes indistinguishable from metastatic tumor and meningioma. At surgery, one patient underwent radical tumor excision, two partial removal, and six biopsy only. Histologic examination revealed one tumor to be of the diffuse small cell type, three of the medium cell type, and five of the large cell type (Lymphoma Study Group classification). Of seven tumors in which lymphocytes were examined by peroxidase-antiperoxidase staining, four were of the B cell type. Postoperatively, whole brain irradiation with 29 to 46 Gy was followed by local irradiation with 15 to 50 Gy. If the tumor persisted, one of three chemotherapies was administered. In one case, methotrexate was given intrathecally. Seven patients were divided into two groups: long remission (three) and recurrence (four). These two groups were compared in terms of serum immunoglobulin levels, T and B cell ratios, CSF characteristics, CT features, tumor cell type, and treatment. No clear differences were found.

    A C57BL/6 mouse lymphoma was demonstrated to be of T cell origin by treating the lymphoma cells with anti-Thy 1.2 antisera in a complement-dependent cytotoxicity test. The lymphoma's growth pattern was described using flow microfluorometric determinations and spleen weight progression. C-type particles were identified in electron micrographs of the lymphoma. C57BL/6 mice were immunized against the lymphoma by injecting x-ray inactivated lymphoma cells into the mice. Protection of immunized mice against live lymphoma cells demonstrated tumor antigens on the lymphoma cells. The success of immunization was found to depend on: route of injection, antigen dosage, state of the antigen, number of injections and the vaccination-challenge interval. Attempts were made to passively transfer immunity from immunized C57BL/6 mice which had survived lymphoma challenge to non-treated, syngeneic mice. The route of immunization in the donors influenced the success of passively transferred immunity in the recipients. Serum from days 1 to 3 and days 11 to death (day 17) had an enhancing effect on lymphoma growth. However, sera from days 5 to 9 retarded lymphoma growth. The C57BL/6 lymphoma cells were injected into rabbits and other strains of mice to demonstrate tumor specificity. The lymphoma did not grow in rabbits and only grew in one mouse strain. This strain had the same major histocompatibility loci as C57BL/6 mice. Crosses were made between C57BL/6 mice and a resistant strain of mice (DBA/2 mice). The F 1 hybrids were found to be less susceptible to the lymphoma than the C57BL/6 strain. Sublethal x-irradiation of the F 1 mice decreased its ability to resist the C57BL/6 lymphoma. Immunization with x-ray inactivated C57BL/6 lymphoma cells increased survival after challenge with lymphoma in the F 1 mice

    The proper evaluation of the patient with nasal obstruction relies on a comprehensive history and physical examination. Once the site of obstruction is accurately identified, the patient may benefit from a trial of medical management. At times however, the definitive treatment of nasal obstruction relies on surgical management. Recognizing the nasal septum, nasal valve, and turbinates as possible sites of obstruction and addressing them accordingly can dramatically improve a patient's nasal breathing. Conservative resection of septal cartilage, submucous reduction of the inferior turbinate, and structural grafting of the nasal valve when appropriate will provide the optimal improvement in nasal airflow and allow for the most stable results.

    Conjunctival lymphomas constitute 25% of all ocular adnexal lymphomas. The majority are B-cell non-Hodgkin lymphomas (NHLs) (98%), whereas conjunctival T-cell NHLs are rare (2%). The most frequent subtype of conjunctival B-cell lymphoma is extranodal marginal zone lymphoma (EMZL; 81%), followed...... by follicular lymphoma (8%), diffuse large B-cell lymphoma (3%), and mantle cell lymphoma (3%). Extranodal marginal zone lymphoma occurs slightly more often in women and, along with follicular lymphoma, presents late in the seventh decade of life, whereas diffuse large B-cell lymphoma and especially mantle cell...... lymphoma have a predilection for the male gender and typically present in the eighth decade. Extranodal marginal zone lymphoma and follicular lymphoma present most frequently in the forniceal and bulbar conjunctiva.

    Full Text Available ABSTRACT INTRODUCTION: Obstructive sleep apnea syndrome (OSAS is a common disorder that can lead to cardiovascular morbidity and mortality, as well as to metabolic, neurological, and behavioral consequences. It is currently believed that nasal obstruction compromises the quality of sleep when it results in breathing disorders and fragmentation of sleep. However, recent studies have failed to objectively associate sleep quality and nasal obstruction. OBJECTIVE: The aim of this systematic review is to evaluate the influence of nasal obstruction on OSAS and polysomnographic indices associated with respiratory events. METHODS: Eleven original articles published from 2003 to 2013 were selected, which addressed surgical and non-surgical treatment for nasal obstruction, performing polysomnography type 1 before and after the intervention. RESULTS/CONCLUSIONS: In most trials, nasal obstruction was not related to the apnea-hypopnea index (AHI, indicating no improvement in OSAS with reduction in nasal resistance. However, few researchers evaluated other polysomnography indices, such as the arousal index and rapid eye movement (REM sleep percentage. These could change with nasal obstruction, since it is possible that the nasal obstruction does not completely block the upper airways, but can increase negative intrathoracic pressure, leading to sleep fragmentation.

    Prognosis of patients with localized nasal extranodal natural killer/T-cell lymphoma, nasal type (ENKL) has been improved by non-anthracycline-containing treatments such as concurrent chemoradiotherapy (CCRT). However, some patients experience early disease progression. To clarify the clinical features and outcomes of these patients, data from 165 patients with localized nasal ENKL who were diagnosed between 2000 and 2013 at 31 institutes in Japan and who received radiotherapy with dexamethasone, etoposide, ifosfamide, and carboplatin (RT-DeVIC) were retrospectively analyzed. Progression of disease within 2 years after diagnosis (POD24) was used as the definition of early progression. An independent dataset of 60 patients with localized nasal ENKL who received CCRT at Samsung Medical Center was used in the validation analysis. POD24 was documented in 23% of patients who received RT-DeVIC and in 25% of patients in the validation cohort. Overall survival (OS) from risk-defining events of the POD24 group was inferior to that of the reference group in both cohorts (P < .00001). In the RT-DeVIC cohort, pretreatment elevated levels of serum soluble interleukin-2 receptor (sIL-2R), lactate dehydrogenase, C-reactive protein, and detectable Epstein-Barr virus DNA in peripheral blood were associated with POD24. In the validation cohort, no pretreatment clinical factor associated with POD24 was identified. Our study indicates that POD24 is a strong indicator of survival in localized ENKL, despite the different CCRT regimens adopted. In the treatment of localized nasal ENKL, POD24 is useful for identifying patients who have unmet medical needs. © 2018 The Authors.

    To compare the benefits of ventilated nasal packing with traditional vaseline guaze nasal packing. Study Design: Randomized controlled trial. Place and Duration of Study: This study was conducted at CMH Multan, from Jun 2014 to Dec 2014. Material and Methods: In this study, sample size of 80 patients was calculated using WHO calculator. Patients were divided in two groups using lottery method endotracheal tube and piece of surgical glove filled with ribbon guaze was utilized for fabricated ventilated nasal pack and compared with traditional nasal packs. Nasal obstruction and sleep disturbance were studied at eight hours and twenty-four hours following surgery using visual analog scale. Results: Mean nasal obstruction with ventilated nasal pack was 45.62 +- 6.17 and with Vaseline nasal pack was 77.67 +- 4.85 which was statistically significant (p=0.001) in both the groups. Mean sleep disturbance in both the groups was 46.32 +- 5.23 and 68.75 +- 2.70 respectively which was statistically significant (p=0.001) in both the groups. Conclusion: Patients with ventilated nasal packs were found to have better tolerance to nasal packs due to less nasal obstruction and sleep disturbance

    Pileri, Stefano; Ponzoni, Maurilio

    Nodal marginal zone B cell lymphomas (NMZLs) are a rare group of lymphoid disorders part of the spectrum of marginal zone B-cell lymphomas, which encompass splenic marginal one B-cell lymphoma (SMZL) and extra nodal marginal zone of B-cell lymphoma (EMZL), often of MALT-type. Two clinicopathological forms of NMZL are recognized: adult-type and pediatric-type, respectively. NMZLs show overlapping features with other types of MZ, but distinctive features as well. In this review, we will focus on the salient distinguishing features of NMZL mostly under morphological/immunophenotypical/molecular perspectives in views of the recent acquisitions and forthcoming updated 2016 WHO classification of lymphoid malignancies.

    Sensory attributes of intranasal corticosteroids, such as rundown to the back of the throat, may influence patient treatment preferences. This study compares the nasal deposition and nasal retention of a radiolabeled solution of ciclesonide nasal aerosol (CIC-hydrofluoroalkane [HFA]) with a radiolabeled suspension of mometasone furoate monohydrate aqueous nasal spray (MFNS) in subjects with either perennial allergic rhinitis (AR) or seasonal AR. In this open-label, single-dose, randomized, crossover scintigraphy study, 14 subjects with symptomatic AR received a single dose of radiolabeled 74-μg CIC-HFA (37 μg/spray, 1 spray/each nostril) via a nasal metered-dose inhaler or a single dose of radiolabeled 200-μg MFNS (50 μg/spray, 2 sprays/each nostril), with a minimum 5-day washout period between treatments. Initial deposition (2 minutes postdose) of radiolabeled CIC-HFA and MFNS in the nasal cavity, nasopharynx, and on nasal wipes, and retention of radioactivity in the nasal cavity and nasal run-out on nasal wipes at 2, 4, 6, 8, and 10 minutes postdose were quantified with scintigraphy. At 2 and 10 minutes postdose, deposition of radiolabeled CIC-HFA was significantly higher in the nasal cavity versus radiolabeled MFNS (99.42% versus 86.50% at 2 minutes, p = 0.0046; and 81.10% versus 54.31% at 10 minutes, p Deposition of radioactivity on nasal wipes was significantly higher with MFNS versus CIC-HFA at all five time points, and posterior losses of radiolabeled formulation were significantly higher with MFNS at 6, 8, and 10 minutes postdose. In this scintigraphic study, significantly higher nasal deposition and retention of radiolabeled aerosol CIC-HFA were observed versus radiolabeled aqueous MFNS in subjects with AR.

    2016-01-01

    Full Text Available We describe the case of a 13-year-old boy who presented with persistent thrombocytopenia during maintenance chemotherapy with mercaptopurine and methotrexate for T cell lymphoblastic lymphoma. He was diagnosed with immune thrombocytopenia (ITP after thorough investigations for the relapse of lymphoma and was successfully treated with immunoglobulin and steroids. ITP is known to be associated with chronic lymphocytic leukemia, Hodgkin lymphoma, and various types of non-Hodgkin lymphoma but rarely with T cell non-Hodgkin lymphoma or in children. Diagnosis of ITP with lymphoma is challenging due to the many factors affecting platelet counts, and ITP often complicates the diagnosis or treatment course of lymphoma. The underlying mechanism of ITP with NHL is still unclear. Drug-induced immunomodulation with a reduction of regulatory T cells might have contributed to the development of ITP in our case.

    The purpose of this study was to examine, retrospectively, national-wide clinical data of patients with localized extranodal non-Hodgkin's lymphoma (NHL) who were treated by radiation therapy with or without chemotherapy. The survey was carried out at 25 radiation oncology institutions in Japan in 1998. In 1999, according to the Revised European American Lymphoma (REAL) classification, central pathological review conducted at Aichi cancer center was carried out for the data from 7 radiation oncology institutions. The 5-year progression free survival rates (PFS) were calculated to identify prognostic factors. Survey: Data from 1, 141 patients with stage I and II NHL were recruited from 1988 through 1992. Of them, 787 patients, who were treated using definitive radiotherapy with or without chemotherapy for intermediate and high-grade lymphomas in Working Formulation, constituted the core of this study. Primary tumors arose mainly from extra-nodal organs (71%) in the head and neck (Waldeyer's ring: 41%, thyroid gland: 7%, nasal cavities: 5%, oral cavities: 4%, sinus: 3%, orbital structures: 3%, skin: 2% and etc.). The median age of 60 years for patients with extra-nodal NHL was higher than that of 56 years for patients with nodal NHL (p<0.01). Female were dominant in incidence of extra-nodal NHL arising from the thyroid gland, skin and gastrointestinal tract. The percentage of stage I to the extra-nodal NHL from orbit, sino-nasal presentation was higher than that of other NHLs. The percentage of stage II to the extra-nodal NHL from Waldeyer's ring and thyroid gland was higher than that of other NHLs. Central pathological review was carried out for pathological data from 79 patients (Waldeyer's ring: 45, thyroid gland: 19, sinonasal cavities: 15). Of these, diffuse large B cell lymphoma (DLBCL) composed 63% of all patients, mucosa associated lyumphoid tissue lymphoma (MALT-L): 16%, Natural Killer/T cell lymphoma (NK/T-L): 11%, and mantle cell lymphoma: 5% in REAL

    The syncytiotrophoblast layer of the human placenta has an important role in limiting transplacental viral spread from mother to fetus. Human cytomegalovirus (HCMV) is capable of establishing a latent infection in syncytiotrophoblast cells, with restriction of gene expression to immediate-early and early proteins. We analyzed the extent of replication of human T cell leukemia-lymphoma virus type I (HTLV-I) in human term syncytiotrophoblasts infected with HTLV-I alone or coinfected with HTLV-I and HCMV. Although syncytiotrophoblasts could be infected with cell-free HTLV-I, no viral protein expression was found in the singly infected cells. On the contrary, coinfection of the cells with HTLV-I and HCMV resulted in simultaneous replication of both viruses. Bidirectional enhancing activities between HTLV-I and HCMV were mediated primarily by the Tax and immediate-early proteins, respectively. The stimulatory effect of HTLV-I Tax on HCMV replication appeared to be mediated partly by tumor necrosis factor beta and transforming growth factor beta-1. We observed formation of pseudotypes with HTLV-I nucleocapsids within HCMV envelopes, whereas HCMV was not pseudotyped by HTLV-I envelopes in dually infected syncytiotrophoblast cells. Our data suggest that in vivo dual infection of syncytiotrophoblast cells with HTLV-I and HCMV may facilitate the transplacental transmission of both viruses.

    The size and configuration of the nasal airways of humans change with time as a result of the normal process of congestion/decongestion of the erectile tissue of the nasal mucosa. To determine the extent to which airway areas change in vivo, we used magnetic resonance imaging (MRI) to quantitate both the cross-sectional area and perimeter of coronal sections of the entire nasal airway of a human subject. Changes in airway size or patency were indexed to measured changes in unilateral nasal airway resistance determined by posterior rhino manometry. The results of this study in which two MRI scans were performed for presumed left-side patency and two for right-side patency, showed that changes in nasal airway resistance were difficult to ascribe to systematic changes In the sizes of the airways.

    The broad category of non-Hodgkin's lymphoma includes a large variety of different diseases including indolent as well as aggressive lymphomas. Mucosa-associated lymphoid tissue (MALT) lymphoma arises in the extranodal mucosal lymphoid tissue and has only been recognised as a distinct entity in recent years. It affects one or several extranodal structures such as the stomach, the lung, the eye and salivary glands. The lymphoma is generally of low grade and has indolent course. The aim of this article is to exemplify the most common radiological patterns of MALT lymphoma. (orig.)

    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 majority of lymphomas are sensitive and respond well to relatively low doses of irradiation. Careful staging of Hodgkin's disease patients selects the patients who can be cured with irradiation alone, and the combination of chemotherapy and irradiation may result in cure of complete remission in all types of lymphoma. In non-Hodgkin's disease and late stage Hodgkin's disease, radiotherapy is a very useful modality for palliating bulky disease, and treating bone infliltration or other painful areas

    Somatostatin receptor (SSTR) scintigraphy and gallium-67 citrate ( 67 Ga) scintigraphy have been used for visualisation of Hodgkin's lymphoma and non-Hodgkin's lymphoma. However, experience with B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) type is very limited. The aim of this study was to prospectively compare the 67 Ga scintigraphy results with those obtained by 111 In-DOTA-dPhe 1 -Tyr 3 -octreotide ( 111 In-DOTA-TOCT) and 111 In-DOTA-lanreotide ( 111 In-DOTA-LAN) scintigraphy in patients with proven MALT-type lymphoma. Comparative scintigraphic examinations using 67 Ga, 111 In-DOTA-TOCT and 111 In-DOTA-LAN were performed in 18 patients (11 female and 7 male, median age 64±15 years) with histologically verified MALT-type lymphomas of various origin. Planar and single-photon emission tomography imaging acquisitions were performed after injection of a mean dose of 185±26 MBq 67 Ga and 165±20 MBq 111 In-DOTA-TOCT or 111 In-DOTA-LAN. All scintigraphic results were correlated with other conventional examinations including gastroscopy, colonoscopy, endosonoscopy, ophthalmologic investigation, CT of the thorax and abdomen and bone marrow biopsy. This comparative study showed that 67 Ga scintigraphy found abnormalities in 10 of 16 patients (63%) and detected 18 of 31 clinically involved sites (58%), but was false positive in three patients. 111 In-DOTA-TOCT found abnormalities in 9 of 15 patients (60%) and detected 15 of 27 clinical lesions (56%); it was false positive in two patients. 111 In-DOTA-LAN scintigraphy showed abnormalities in 7 of 11 patients (64%) and found 12 of 22 clinical lesions (55%). False-positive 111 In-DOTA-LAN scan results were found in two patients. For supra-diaphragmatic lesions, 67 Ga scintigraphy detected 12 of 16 sites (75%). 111 In-DOTA-TOCT scintigraphy revealed 7 of 15 lesions (47%). 111 In-DOTA-LAN showed 6 of 12 positive sites (50%). For infra-diaphragmatic involvement, the sensitivities of 67 Ga, 111 In

    Vitreoretinal lymphoma, which most commonly is diffuse large B cell non-Hodgkin in type, is a rare cancer with high morbidity and high mortality. Making a tissue diagnosis of vitreoretinal lymphoma is a major challenge for clinicians due to biological and technical factors. Yet, the delay in start of treatment may have vision- and life- threatening consequences, and there is considerable interest in the application of molecular assays to improve the accuracy of the diagnostic process: detection of a clonal immunoglobulin heavy chain rearrangements in lymphoma cells by polymerase chain reaction; measurement of vitreous or aqueous interleukin-10 protein levels in ocular fluids; and identification of mutations in the myeloid differentiation primary response gene 88 in tumour cells. In this article, we review the historical development and current application of each of these molecular methods. We also discuss future opportunities for the molecular diagnosis of vitreoretinal lymphoma through next generation sequencing technologies. This article is protected by copyright.

    115 patients with lymphoid tumours presenting in the orbit were seen between 1970 and 1984. The histological types were high-grade malignant lymphoma - 18, low-grade malignant lymphoma - 43, and indeterminate lymphocytic lesions - 54. Eighteen patients were found to have disseminated lymphoma at presentation. The majority of the patients received radiotherapy to the orbit; local control was achieved in all cases and the ocular morbidity from radiotherapy was low with 11 patients developing lens opacities and 5 a dry eye. Survival of patients with stage I low-grade lymphoma adn indeterminate lymphocytic lesions was similar to that of a normal population of the same age distribution. The clinic features and dissemination pattern of the low-grade malignant lymphomata and the indeterminate lymphocytic lesions were identical, suggesting that most, if not all, lymphoid masses presenting in the orbit are neoplastic rather than reactive in nature. 28 refs.; 4 figs.; 5 tabs

    The nasal septum is a particularly rare site of origin of chondrosarcoma. Cranial base invasion may be at hand, with such lesions making complete tumor removal difficult. MRI techniques allow precise definition of tumor extent. In the described case, CT and Dynamic MR imaging were performed in a case of chondrosarcoma of the nasal septum. Imaging clearly illustrated size and extent of the mass with central regions of internal calcification. Dynamic MRI was additionally performed, which helped to define the presumed origin of the lesion from the nasal septum. (orig.)

    2001-03-01

    During the past decade, mantle-cell lymphoma has been established as a new disease entity. The normal counterparts of the cells forming this malignant lymphoma are found in the mantle zone of the lymph node, a thin layer surrounding the germinal follicles. These cells have small to medium-sized nuclei, are commonly indented or cleaved, and stain positively with CD5, CD20, cyclin D1, and FMC7 antibodies. Because of its morphological appearance and a resemblance to other low-grade lymphomas, many of which grow slowly, this lymphoma was initially thought to be an indolent tumour, but its natural course was not thoroughly investigated until the 1990s, when the BCL1 oncogene was identified as a marker for this disease. Mantle-cell lymphoma is a discrete entity, unrelated to small lymphocytic or small-cleaved-cell lymphomas.

    A 65-year old patient, with no medical history, was admitted for lower gastrointestinal bleeding. On clinical examination the patient seemed to be in good health. However the examination was completed with a rectosigmoidoscopy revealing the presence of mucosal erosions, ulcerations, multiple papulae. The histopathological examination raised the suspicion of a colonic lymphoma. Gastric biopsies suggested a gastric MALT type lymphoma associated to the colonic lymphoma, but the immunohistochemical profile corresponded to a mantle cell lymphoma. In spite of the general poor prognosis of mantle cell lymphoma, our patient had a good clinical and endoscopic response to the standard cyclophosphamide, vincristine, prednisone (CVP) therapy. The cases of gastric and colonic mantle lymphoma are rare, the response to therapy is poor; fortunately, our patient had a complete resolution after completion of the six cycles of chemotherapy.

    Full Text Available Unilateral sinus disease (USD can sometimes be difficult to accurately diagnose before surgery. The application of nasal nitric oxide (nNO for USD diagnosis and its surgical outcome in USD has not been reported in the literature. We prospectively enrolled sixty-six USD patients who underwent endoscopic sinus surgery for fungal rhinosinusitis (n = 19, chronic rhinosinusitis (CRS without nasal polyps (n = 13, CRS with nasal polyps (n = 12 and sinonasal mass lesions (n = 22. nNO levels were measured preoperatively and at three and six months postoperatively. Correlations between nNO levels and potential clinical parameters, type of disease, disease severity, and disease-related quality of life (QOL were assessed. Unlike bilateral CRS, in USD, nNO levels did not correlate with disease severity or postoperative QOL improvements. Except for fungus group, there were no differences in nNO levels between lesion and non-lesion sides in all the other groups. nNO levels on both sides were significantly elevated six months postoperatively in all groups. Fungal rhinosinusitis patients had the lowest preoperative nNO levels, and a cutoff of 239.3 ppb had the best sensitivity (79.0% and specificity (87.2% for preoperative diagnosis. While preoperative nNO levels cannot serve as an alternative marker for disease severity of USD, they were lower in fungal rhinosinusitis patients than in other USD patients and may be useful for more accurate diagnosis prior to surgery.

    Immunophenotype of primary cutaneous diffuse large B-cell lymphoma, leg-type (PCLBCL-LT) suggests a germinal center-experienced B lymphocyte (BCL2+ MUM1+ BCL6+/-). As maturation history of B-cell is "imprinted" during B-cell development on the immunoglobulin gene sequence, we studied the structure and sequence of the variable part of the genes (IGHV, IGLV, IGKV), immunoglobulin surface expression and features of class switching in order to determine the PCLBCL-LT cell of origin. Clonality analysis with BIOMED2 protocol and VH leader primers was done on DNA extracted from frozen skin biopsies on retrospective samples from 14 patients. The clonal DNA IGHV sequence of the tumor was aligned and compared with the closest germline sequence and homology percentage was calculated. Superantigen binding sites were studied. Features of selection pressure were evaluated with the multinomial Lossos model. A functional monoclonal sequence was observed in 14 cases as determined for IGHV (10), IGLV (2) or IGKV (3). IGV mutation rates were high (>5%) in all cases but one (median:15.5%), with superantigen binding sites conservation. Features of selection pressure were identified in 11/12 interpretable cases, more frequently negative (75%) than positive (25%). Intraclonal variation was detected in 3 of 8 tumor specimens with a low rate of mutations. Surface immunoglobulin was an IgM in 12/12 cases. FISH analysis of IGHM locus, deleted during class switching, showed heterozygous IGHM gene deletion in half of cases. The genomic PCR analysis confirmed the deletions within the switch μ region. IGV sequences were highly mutated but functional, with negative features of selection pressure suggesting one or more germinal center passage(s) with somatic hypermutation, but superantigen (SpA) binding sites conservation. Genetic features of class switch were observed, but on the non functional allele and co-existing with primary isotype IgM expression. These data suggest that cell-of origin is

    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.

    Among Epstein-Barr virus (EBV)-positive cytotoxic T/NK-cell lymphoma, there are only a few reports on the clinicopathologic features of patients with primary nodal presentation (nodal EBV cytotoxic T-cell lymphoma [CTL]). Here, we compared the clinicopathologic profiles of 39 patients with nodal EBV CTL with those of 27 cases of "extranasal" NK/T-cell lymphoma of nasal type (ENKTL), especially addressing their T-cell receptor (TCR) phenotype. Histologically, 22 of 39 nodal EBV CTL cases (56%) were unique in having centroblastoid appearance, which was contrasted with the lower incidence of this feature in ENKTL (15%, P=0.001). In contrast, pleomorphic appearance was more frequently seen in ENKTL than in nodal EBV CTL (67% vs. 23%, P=0.001). Thirty-three of 39 nodal EBV CTL cases (85%) were of T-cell lineage on the basis of TCR expression and/or TCRγ gene rearrangement; in detail, 18 cases (46%) were TCRβ positive (αβ T), 5 (13%) were TCRγ and/or δ positive (γδ T), and 10 (26%) were TCR-silent type with clonal TCRγ gene rearrangement but no expression of TCRβ, γ, or δ. These results were clearly contrasted by a lower incidence of T-cell lineage in ENKTL (7 cases, 26%, P<0.001). Notably, the survival time of the 5 nodal lymphoma patients with γδ T-cell phenotype was within 3 months, which was inferior to those of αβ T and TCR-silent types (P=0.003), and 3 of those with available clinical information were all found to be associated with autoimmune diseases. These data suggest that nodal EBV CTL is distinct from ENKTL.

  9. Bilateral cleft lip nasal deformity

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    Full Text Available Abstract Background Reusable nasal-spray devices are frequently used in otolaryngologic examinations, and there is an increasing concern about the risk of cross-contamination from these devices. The aim of our study was to determine, by means of microbiologic analysis, the safety of a positive-displacement or pump-type atomizer after multiple uses. Methods A reusable nasal spray bottle, pump, and tips were used in the nasal physical examination of 282 patients admitted to a tertiary otolaryngology clinic. The effectiveness of 2 different methods of prophylaxis against microbiologic contamination (the use of protective punched caps or rinsing the bottle tip with alcohol was compared with that of a control procedure. Results Although there was no statistically significant difference in positive culture rates among the types of nasal spray bottles tested, methicillin-resistant coagulase-negative staphylococci were isolated in 4 of 198 cultures. Conclusion Given these findings, we concluded that additional precautions (such as the use of an autoclave between sprays, disposable tips, or disposable devices are warranted to avoid interpatient cross-contamination from a reusable nasal spray device.

  14. Nasal Delivery of High Molecular Weight Drugs

    Directory of Open Access Journals (Sweden)

    Erdal Cevher

    2009-09-01

    Full Text Available Nasal drug delivery may be used for either local or systemic effects. Low molecular weight drugs with are rapidly absorbed through nasal mucosa. The main reasons for this are the high permeability, fairly wide absorption area, porous and thin endothelial basement membrane of the nasal epithelium. Despite the many advantages of the nasal route, limitations such as the high molecular weight (HMW of drugs may impede drug absorption through the nasal mucosa. Recent studies have focused particularly on the nasal application of HMW therapeutic agents such as peptide-protein drugs and vaccines intended for systemic effects. Due to their hydrophilic structure, the nasal bioavailability of peptide and protein drugs is normally less than 1%. Besides their weak mucosal membrane permeability and enzymatic degradation in nasal mucosa, these drugs are rapidly cleared from the nasal cavity after administration because of mucociliary clearance. There are many approaches for increasing the residence time of drug formulations in the nasal cavity resulting in enhanced drug absorption. In this review article, nasal route and transport mechanisms across the nasal mucosa will be briefly presented. In the second part, current studies regarding the nasal application of macromolecular drugs and vaccines with nanoand micro-particulate carrier systems will be summarised.

    The airway geometry of the nasal cavity is manifestly complex, and the manner in which it controls the airflow to accomplish its various physiological functions is not fully understood. Since the complex morphology and inaccessibility of the nasal passageways precludes detailed in-vivo measurements, either computational simulation or in-vitro experiments are needed to determine how anatomical form and function are related. The fabrication of a replica model of the nasal cavity, of a high optical clarity and derived from in-vivo scan data is described here, together with characteristics of the flow field investigated using particle image velocimetry (PIV) and flow visualization. Flow visualization is shown to be a capable and convenient technique for identifying key phenomena. Specifically the emergence of the jet from the internal nasal valve into the main cavity, how it impacts on the middle turbinate, and the large enhancement of dispersion that accompanies the initial appearance of flow instability are revealed as particularly significant features. The findings from the visualization experiments are complemented by PIV imaging, which provides quantitative detail on the variations in velocity in different regions of the nasal cavity. These results demonstrate the effectiveness of the cavity geometry in partitioning the flow into high shear zones, which facilitate rapid heat transfer and humidification from the nasal mucosa, and slower zones affording greater residence times to facilitate olfactory sensing. The experimental results not only provide a basis for comparison with other computational modelling but also demonstrate an alternative and flexible means to investigate complex flows, relevant to studies in different parts of the respiratory or cardiovascular systems.

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL of the breast constitutes 0.04%-0.53% of all malignancies and 2.2% of extra nodal lymphomas. In total, 7%-8% of all B-cell lymphomas are the mucosa-associated lymphoid tissue (MALT type, of which up to 50% of primary gastric MALT lymphoma. Herein we present a patient with breast MALT lymphoma that transformed to diffuse large B-cell lymphoma (DLBCL. A 69-year-old female presented with a mass on her left breast. Physical examination showed a 3 × 3-cm mass located 1 cm from the areola on the upper lateral quadrant of the breast at the 1 o’clock position, which was fixed and firm. Excisional biopsy was performed and pathologic examination of the specimen showed MALT lymphoma transformation to DLBCL. The patient was staged as II-EA. The rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP protocol was scheduled as treatment. Following 6 courses of R-CHOP, 2 additional courses of rituximab were administered. Positron emission tomography (PET-CT was done at the end of the treatment. PET showed that the patient was in complete remission. At the time this report was written, the patient was being followed-up at the outpatient clinic on a regular basis. Lymphoma of the breast is a rarity among malignant tumors of the breast. The most common type of lymphoma is DLBCL. Breast MALT lymphoma is extremely rare. Primary MALT lymphoma of the breast can transform from low grade to high grade and recurrence is possible; therefore, such patients should be monitored carefully for transformation.

    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

    Haemangiopericytomas (HPC) are rare vascular tumours originating from a pericytes, a term coined by Zimmermann to refer to the main location of this cell line in the pericapillary connective tissue. HPC may arise in any part of the body. We report a 29-year-old man with a histologically proven nasal haemangiopericytoma-like tumour. The lesion was embolised through the ophthalmic artery before it was removed surgically. The main symptoms of nasal HPC are epistaxis and obstruction of the nose. Malignant and benign clinical courses have been described. Local recurrence and metastases may be observed years after initial diagnosis. (orig.)

    Failure of the anterior neuropore can lead to three main types of anomalies: nasal dermal sinus, encephalocele and nasal glioma or heterotopia. In this report, we describe a case of intracranial and extracranial glial heterotopia that probably resulted from a common failure of anterior neuropore development. We describe the prenatal radiological assessment based on ultrasound and MRI results, and consider their limitation for early fetal diagnosis. We also discuss the embryogenesis and the possible pathogenic mechanisms involved. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  5. Does Post Septoplasty Nasal Packing Reduce Complications?

    Full Text Available The main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. Also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. Due to the above mentioned problems and in order to solve and minimize them nasal packing, nasal splint and nasal mold have been advised. Patients for whom the nasal packing used may faced to some problems like naso-pulmonary reflex, intractable pain, sleep disorder, post operation infection and very dangerous complication like toxic shock syndrome. We have two groups of patients and three surgeons (one of the surgeons used post operative nasal packing in his patients and the two others surgeons did not.Complications and morbidities were compared in these two groups. Comparing the two groups showed that the rate of complication and morbidities between these two groups were same and the differences were not valuable, except the pain and discomfort post operatively and at the time of its removal. Nasal packing has several risks for the patients while its effects are not studied. Septoplasty can be safely performed without postoperative nasal packing. Nasal packing had no main findings that compensated its usage. Septal suture is one of the procedures that can be used as alternative method to nasal packing. Therefore the nasal packing after septoplasty should be reserved for the patients with increased risk of bleeding.

  7. Non-Hodgkin's lymphomas

    1987-01-01

    Non-Hodgkin's lymphomas are a varied and complex group of diseases that must be distinguished from Hodgkin's disease. The latter almost always begins in lymph nodes and spreads primarily in an axial fashion; non-Hodgkin's lymphomas may begin either in lymph nodes or in extranodal tissue and can spread both in an axial fashion and centrifugally. Because of changes in pathology terminology and the introduction of a classification using cell surface markers, many prognostic groups of patients with lymphomas have evolved. Therapeutic choices and prognosis are greatly influenced by variations in anatomic sites and extent of disease. Currently, the decisions on management require a balancing of radiation therapy with systemic chemotherapy. In some cases, radiation therapy alone may be sufficient; however, because most patients with non-Hodgkins's lymphomas tend to have advanced disease, a large percentage of patients will be managed with chemotherapy alone or in combination with radiation therapy

    1982-01-01

    The clinical course and biopsy specimens from 515 consecutive non-Hodgkin's lymphoma patients was evaluated retrospectively in an attempt to determine the clinical importance of documented changes in histology over time. Two-hundred and five of these patients has an initial diagnosis of nodular lymphoma and were reviewed for this anaysis. Sixty-three underwent a repeat biopsy greater than 6 mo after initial diagnosis. In 23 patients, these repeat biopsies revealed a change in histology to a diffuse pattern and/or a change to a larger ''histiocytic'' cell type, while repeat biopsies for the other 40 (63%) disclosd persistence of a nodular pattern and no clear change in basic cell type. Progression from nodular lymphoma to diffuse histiocytic, mixed, or undifferentiated types of lymphomas of Rappaport was found in repeate biopsies obtained from 19 patients (30%). Prognosis for survival following a biopsy that demonstrated histologic change was related to the histology demonstrated at the most recent biopsy and to the response to subsequent drug treatment. Survival following repeat biopsy for these 19 patients was significantly shorter than for the 40 patients whose histology remained nodular (p < 0.001). However, attainment of a complete remission with intensive combination chemotherapy was associated with prolonged survival in eight patients and prolonged disease-free survival in one patient. Since prior treatment may compromise the ability to achieve a complete response to chemotherapy in patients with nodular lymphoma who develop an aggressive diffuse histology, the likelihood of histologic progression must be considered in the design of future clinical trials in nodular lymphoma. Histologic progression does not preclude attainment of a complete response to intensive chemotherapy

    2015-01-01

    Full Text Available Nasal glomangiopericytoma is rare. The immunophenotype is heterogeneous, more frequently smooth-muscle-actin and CD34-positive. We report expression patterns for several vascular-related proteins such as CD99, CD146, Bcl2, and WT1 as well as for treatment-related proteins such as mTOR and EGFR in a nasal glomangiopericytoma. The patient (woman, 86 years presented with a left nasal tumefaction. The resected specimen (1.5-cm showed a glomangiopericytoma. Tumor cells expressed smooth-muscle-actin, CD31, CD34, and progesterone receptor. They also expressed the vascular-cell-related proteins Bcl2, CD99, CD146, and WT1, as well as mTOR and EGFR. Nasal glomangiopericytomas show immunohistochemical heterogeneity for vascular-related markers, suggesting a possible extensive pericytic differentiation. The expression of potential targets for drug treatments such as mTOR and EGFR may impact on the clinical follow-up of these tumors occurring at advanced ages, which may require complex surgery.

    Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. 24 year old male patient carrying the Human Immunodeficiency Virus, who began with signs and symptoms of acute abdomen and fever 72 hours before arriving in the emergency room. A computed tomography was performed that showed free fluid in the cavity, and gastric wall thickening. The patient underwent a laparotomy, finding absence of the anterior wall of the stomach, sealed with the left lobe of the liver, colon and omentum. Total gastrectomy, with oesophagosty and jejunostomy tube, was performed. Gastric perforation secondary to a MALT lymphoma is rare, with high mortality. There is limited information reported of this complication and should be highly suspected in order to provide appropriate treatment for a complication of this type.

Development of nitrogen mustard formulations and treatment regimens has been studied extensively over the last 40 years. In the last 5 years, a new gel formulation has been developed that is associated with a decrease in delayed hypersensitivity reactions. The authors in this review found that while the gel formulation may result in a decrease of allergic contact dermatitis, this advantage has been replaced by a higher number of irritant contact reactions and a decrease in complete response rate. The gel formulation has a complete response rate of 13.8%, which is a decrease in efficacy when compared to aqueous-based preparations of similar concentrations.

    Daniel, M; Raghavan, U

    2005-01-01

    Objectives: To find if the presence of epistaxis after nasal trauma can be used to predict post-traumatic external nasal deformity or a symptomatic deviated nasal septum. Methods: Retrospective analysis of all patients seen in the fractured nose clinic by the first author between 17 October 2003 and 27 February 2004. Presence of epistaxis, newly developed external nasal deformity, and the presence of a deviated nasal septum with new symptoms of nasal obstruction were noted. Results: A total of 139 patients were included in the study. Epistaxis following injury was noted in 106 (76%). Newly developed external nasal deformity was noted in 71 (51%), and 33 (24%) had a deviated nasal septum with new symptoms of nasal obstruction. Of the 106 patients with post-trauma epistaxis, 50 (67%) had newly developed external nasal deformity and of the 33 patients without post-traumatic epistaxis, 11 (33%) had nasal deformity (pepistaxis was not associated with the presence of a newly symptomatic deviated septum (25% in patients with epistaxis after injury versus 18% if there was no epistaxis). Conclusions: Presence of epistaxis after nasal trauma is associated with a statistically significant increase in external nasal deformity. However, one third of patients without epistaxis following nasal trauma also had external nasal deformity and hence all patients with a swollen nose after injury, irrespective of post-trauma epistaxis, still need to be referred to the fractured nose clinic.

    Objective: To analyze MR imaging manifestations of spinal area lymphoma in order to improve the recognition and understanding of the disease. Methods: A group of 45 patients with pathologically or clinically proven spinal area lymphoma were reviewed. Five cases were primary NHL, 40 cases were secondary with 9 HL and 31 NHL (27 B-cell type NHL and 4 T-cell type NHL). MR Imaging findings were analyzed and correlated with clinical and pathologic findings. Results: (1) Location of lesions: 13 cases were focal type and 32 cases were multifocal type. All of the 5 patients with primary lymphoma were focal type, while 32 of 40 eases of secondary lymphoma were multifocal type. (2)Type of lesions: (1) Vertebral destruction: 27 cases manifested as bone destruction with 23 of them had soft tissue mass and the extent of soft tissue masses were larger than that of bone destruction in 18 eases. (2) Soft tissue masses: 6 cases manifested as soft masses without obvious bone destruction, of which 5 cases had soft tissue masses imbedded vertebrae and communicated paravertebral and epidural spaces through intervertebral foramen. (3) Bone marrow infiltration: 9 cases of secondary spinal lymphoma had signal intensity changes of bone marrow without obvious cortical bone destruction and soft tissue mass. (4) Spinal cord infiltration: 3 cases of secondary spinal lymphoma had spinal cord swelling and signal intensity changes. (3) MRI findings: all lesions of bone destruction and marrow infiltration manifested as hypointense on T 1 -weighted images, hypointense, isointense or hyperintense on T 2 -weighted images and hyperintense on T 2 -weighted images with fat-suppression technique. All soft tissue masses were homogeneous hypointense on T 1 -weighted images and hyperintense on T 2 -weighted images. After intravenous injection of contrast media, the lesions of the bone and the soft tissue showed mild or moderate enhancement without remarkable cystic degeneration and necrosis. Conclusions

    Since the recognition of the anaplastic large-cell lymphomas in the 1980s, much has been learned about the diagnosis, clinical presentation, and treatment of these malignant conditions. The systemic and primary cutaneous types of anaplastic large cell lymphomas have been differentiated on clinical and immunophenotypical findings, but further research is required to elucidate their exact etiologies and pathogeneses. Primary cutaneous anaplastic large-cell lymphoma has a 95% disease-specific 5-year survival, owing partly to the relatively benign course of the disease and partly to the variety of effective treatments that are available. As with many other oncological diseases, new drugs are continually being tested and developed, with immunotherapy and biological response modifiers showing promise.

    Nasal bone fracture is the most common type of facial bone fracture. The optimal duration of the packing after closed reduction has been a controversial issue. The packing has several disadvantages such as blocking the nasal airway, causing infection and a headache, which is the most common immediate complication. The present study investigated the minimal and optimal duration of the nasal packing following reduction surgery of nasal bone fracture. A prospective study was performed for the patients undergoing reduction surgery following nasal bone fracture between July 2010 and June 2012. The patients were categorised into three groups according to the duration of nasal packing. For the patients treated between July 2010 and June 2011, nasal packing was maintained for 5 days. For those between July 2011 and December 2011, packing was maintained for 3 days. For those between January 2012 and June 2012, the packing was removed after 1 day. The computed tomography scan and the cephalolateral X-ray were checked at immediate postoperative period after packing removal and 6 months postoperatively. The alteration of heights, deviations, and nasal bone contours with time passage were compared among three groups. The patient satisfaction survey was also performed and compared. A total of 530 patients including 322 of the 5-days packing group, 102 of the 3-days group, and 106 of the 1-day group were enrolled. There was no statistically significant difference between the groups in terms of heights, deviations, and nasal bone contours (p-value ≥ 0.05). In the patient satisfaction survey, the 1-day packing group complained of discomfort related to nasal packing and headache symptoms much less, compared to the other two groups. The present study demonstrated that 1-day packing had comparable postoperative outcome with reducing the patients' discomfort. As such, a longer packing duration was not needed to achieve stable results one day is a reasonable packing time for most

    As the main mucosal immune inductive site of nasal cavity, nasal-associated lymphoid tissue (NALT) plays an important role in both antigen recognition and immune activation after intranasal immunization. However, the efficiency of intranasal vaccines is commonly restricted by the insufficient intake of antigen by the nasal mucosa, resulting from the nasal mucosal barrier and the nasal mucociliary clearance. The distribution of NALT and the characteristic of nasal cavity have already been described in humans and many laboratory rodents, while data about poultry are scarce. For this purpose, histological sections of the chicken nasal cavities were used to examine the anatomical structure and histological characteristics of nasal cavity. Besides, the absorptive capacity of chicken nasal mucosa was also studied using the materials with different particle size. Results showed that the NALT of chicken was located on the bottom of nasal septum and both sides of choanal cleft, which mainly consisted of second lymphoid follicle. A large number of lymphocytes were distributed under the mucosal epithelium of inferior nasal meatus. In addition, there were also diffuse lymphoid tissues located under the epithelium of the concha nasalis media and the walls of nasal cavity. The results of absorption experiment showed that the chicken nasal mucosa was capable to absorb trypan blue, OVA, and fluorescent latex particles. Inactivated avian influenza virus (IAIV) could be taken up by chicken nasal mucosa except for the stratified squamous epithelium sites located on the forepart of nasal cavity. The intake of IAIV by NALT was greater than that of the nasal mucosa covering on non-lymphoid tissue, which could be further enhanced after intranasal inoculation combined with sodium cholate or CpG DNA. The study on NALT and nasal absorptive capacity will be benefit for further understanding of immune mechanisms after nasal vaccination and development of nasal vaccines for poultry.

    Purpose: The influence of tumor size, grade, thoroughness of staging workup, and radiation dose on disease control, radiation-related complications, and incidence of systemic progression of primary orbital lymphoma is analyzed. Methods and Materials: Twenty patients with Stage I primary orbital lymphoma were treated from August 1976 through August 1991 at Mallinckrodt Institute of Radiology. Staging workups included physical examination, chest x-ray, complete blood count (CBC), liver function test, and computerized tomography (CT) scan of the orbit, abdomen, and pelvis. Nineteen patients had bone marrow biopsy. The histological types based on the National Cancer Institute working formulation were 9 low-grade and 11 intermediate-grade, including five lymphocytic lymphomas of intermediate differentiation. The extension of disease and the volume of tumor were evaluated by CT scan of the orbit. The most commonly used radiation therapy technique was single anterior direct field with 4 MV or 6 MV photons. Lens was shielded or not treated in eight patients. Dose ranged from 20 to 43.2 Gy. Thirteen of 20 patients received 30 Gy. Minimum follow-up was 24 months (median, 4 years). Results: Local control was achieved in all 20 patients. One patient with lymphocytic lymphoma with intermediate differentiation developed disseminated disease. Actuarial disease-free survival (DFS) was 100% and 90% at 2 and 5 years, respectively. No retinopathy was observed. Cataracts were noted in seven patients at 1 to 10 years following irradiation (median, 2 years). Three patients developed lacrimal function disorder, however, no corneal ulceration occurred. Conclusions: Thirty Gy in 15 fractions appears to be a sufficient dose for local control with acceptable morbidity, especially for low-grade, as well as certain types of intermediate-grade lymphomas, such as diffuse small cleaved cell and lymphocytic lymphoma of intermediate differentiation. Systemic dissemination is minimal, provided local

    Purpose: The influence of tumor size, grade, thoroughness of staging workup, and radiation dose on disease control, radiation-related complications, and incidence of systemic progression of primary orbital lymphoma is analyzed. Methods and Materials: Twenty patients with Stage I primary orbital lymphoma were treated from August 1976 through August 1991 at Mallinckrodt Institute of Radiology. Staging workups included physical examination, chest x-ray, complete blood count (CBC), liver function test, and computerized tomography (CT) scan of the orbit, abdomen, and pelvis. Nineteen patients had bone marrow biopsy. The histological types based on the National Cancer Institute working formulation were 9 low-grade and 11 intermediate-grade, including five lymphocytic lymphomas of intermediate differentiation. The extension of disease and the volume of tumor were evaluated by CT scan of the orbit. The most commonly used radiation therapy technique was single anterior direct field with 4 MV or 6 MV photons. Lens was shielded or not treated in eight patients. Dose ranged from 20 to 43.2 Gy. Thirteen of 20 patients received 30 Gy. Minimum follow-up was 24 months (median, 4 years). Results: Local control was achieved in all 20 patients. One patient with lymphocytic lymphoma with intermediate differentiation developed disseminated disease. Actuarial disease-free survival (DFS) was 100% and 90% at 2 and 5 years, respectively. No retinopathy was observed. Cataracts were noted in seven patients at 1 to 10 years following irradiation (median, 2 years). Three patients developed lacrimal function disorder, however, no corneal ulceration occurred. Conclusions: Thirty Gy in 15 fractions appears to be a sufficient dose for local control with acceptable morbidity, especially for low-grade, as well as certain types of intermediate-grade lymphomas, such as diffuse small cleaved cell and lymphocytic lymphoma of intermediate differentiation.

    Transverse nasal groove is a condition of cosmetic concern which awaits due recognition and has been widely described as a shallow groove that extends transversely over the dorsum of nose. However, we observed variations in the clinical presentations of this entity, hitherto undescribed in literature. We conducted a clinicoepidemiological study of transverse nasal lesions in patients attending our outpatient department. We conducted a prospective observational study. We screened all patients attending our out-patient department for presence of transverse nasal lesions, signs of any dermatosis and associated other skin conditions. One hundred patients were recruited in the study. Females (80%) predominated over males. Most patients were of 15-45 years age group (70%). Majority of the transverse nasal lesions were classical transverse nasal groove (39%) and others included transverse nasal line (28%), strip (28%), ridge (4%) and loop (1%). Seborrhoeic diathesis was the most common condition associated with transverse nasal lesion. Occurrence of transverse nasal line, strip, ridge and loop, in addition to classical transverse nasal groove implies that latter is actually a subset of transverse nasal lesions. Common association of this entity with seborrheic dermatitis, seborrhea and dandruff raises a possibility of whether transverse nasal lesion is a manifestation of seborrheic diathesis.

    1970-01-01

    A survey of the incidence of nasal cancer in Northamptonshire during the period 1953 to 1967 is reported. Of the 46 patients with nasal cancer ascertained during the 15-year period 21 (19 males and 2 females) had been employed at some time in the boot and shoe industry. Five other cases diagnosed either before 1953 or after 1967 in persons who had worked in the boot and shoe industry in Northamptonshire were ascertained from various sources. The incidence of nasal cancer (all histological types considered together) was significantly higher in male boot and shoe operatives in Northamptonshire than in males of all occupational classes in the Cancer Register areas selected for comparison and in males working in other occupations in Northamptonshire. The excess incidence has recently given rise to the occurrence of between 1 and 2 new cases per annum in the Northamptonshire boot and shoe industry. The cases within the Northamptonshire industry occurred almost entirely in the relatively small number of workers who are exposed to the dust of the materials used in the manufacture of footwear. Possibly there are two carcinogenic factors in the industry—one related to the production of nasal adenocarcinoma, and the other to squamous and possibly other types of carcinoma in the nasal cavity and sinuses. This requires further study. Our best estimate of the latent period for the adenocarcinoma cases was 54·6 years, which is substantially longer than for the patients with squamous, transitional, and anaplastic tumours (41·7 years). We have no evidence to answer the question whether the facts are still present in the industrial environment, though undoubtedly the standards of hygiene in the industry has improved substantially since these men were first exposed. There is probably an increased risk of nasal adenocarcinoma in the footwear repairing industry, but this requires further study. Our evidence suggests that snuff taking should be considered as a possible contributory

    Misato Ueda, MD

    2017-09-01

    Full Text Available Nasal polyps are inflammatory proliferative tumors arising from the mucosa of the nasal cavity and paranasal sinuses. Although many cases concerning nasal polyps have been reported, those involving external nasal deformities are rare. We report a case of nasal polyposis filling the nasal cavity and paranasal sinuses, leading to external nasal and facial deformities. The condition above is known as Woakes’ syndrome, which is characterized by severe recurrent nasal polyps with deformity of the nasal pyramid, leading to broadening of the nose. We performed nasal osteotomy and facial bone-shaving via the midface degloving approach, which improved the patient’s facial appearance.

    2015-09-01

    Full Text Available Although nasal carriage has been described as a risk factor for Staphylococcus aureus infections in humans, there is a scarcity of studies about S. aureus nasal carriers in animals. In rabbits, S. aureus is one of the most important pathogens responsible for a number of different types of infections. This study was designed to determine the extent of staphylococcal nasal carriage and to establish whether a relationship exists between nasal carriage and development of lesions. One hundred and sixteen rabbits with and without chronic signs of staphylococcosis from 6 industrial rabbitries were monitored. Nasal swabs for microbiological assessments were obtained from all animals. Microbiological results showed that 56% of the animals carried S. aureus in their nasal cavities with significantly higher incidence in animals with staphylococcal-related lesions (84.2% compared to apparently healthy animals (28.8%. Additionally, the S. aureus strains isolated from the nasal cavity and lesions were clonally related in 91.7% of animals. This suggests that nasal carriage of S. aureus in rabbits could be a risk for development of clinical infections.

  12. Detecting Nasal Vowels in Speech Interfaces Based on Surface Electromyography.

    Directory of Open Access Journals (Sweden)

    João Freitas

    Full Text Available Nasality is a very important characteristic of several languages, European Portuguese being one of them. This paper addresses the challenge of nasality detection in surface electromyography (EMG based speech interfaces. We explore the existence of useful information about the velum movement and also assess if muscles deeper down in the face and neck region can be measured using surface electrodes, and the best electrode location to do so. The procedure we adopted uses Real-Time Magnetic Resonance Imaging (RT-MRI, collected from a set of speakers, providing a method to interpret EMG data. By ensuring compatible data recording conditions, and proper time alignment between the EMG and the RT-MRI data, we are able to accurately estimate the time when the velum moves and the type of movement when a nasal vowel occurs. The combination of these two sources revealed interesting and distinct characteristics in the EMG signal when a nasal vowel is uttered, which motivated a classification experiment. Overall results of this experiment provide evidence that it is possible to detect velum movement using sensors positioned below the ear, between mastoid process and the mandible, in the upper neck region. In a frame-based classification scenario, error rates as low as 32.5% for all speakers and 23.4% for the best speaker have been achieved, for nasal vowel detection. This outcome stands as an encouraging result, fostering the grounds for deeper exploration of the proposed approach as a promising route to the development of an EMG-based speech interface for languages with strong nasal characteristics.

  13. Classification of malignant lymphomas

    International Nuclear Information System (INIS)

    Schneider, M.; Thyss, A.

    1986-01-01

    Malignant lymphomas, primary tumors of the lymphoid tissues, were first described in 1832 by Thomas Hodgkin. The histological characteristics were later defined by Sternberg and Reed, and Virchow introduced the concept of lymphosarcoma in 1863. Today, these pathologies are grouped together under the synonymous terms hematosarcoma or malignant lymphoma, which are in turn divided into Hodgkin's disease (HD) and non-Hodgkin's malignant lymphomas (NHL). The therapy of lymphomas is controversial. The validity of treatment for asymptomatic patients is questioned, owing to the indolent course of many lymphomas. Results for histologically unfavorable forms are highly disparate. Exclusive radiotherapy has occasionally produced up to 78% disease-free survival at 5 years for truly localized stages. Today, however, use of chemotherapy/radiotherapy combinations is almost universal, with chemotherapy occasionally being used alone and providing 90% disease-free survival at 5 years. Chemotherapy is the main treatment for disseminated forms; the major associations include doxorubicin hydrochloride (Adriamycin), cyclophosphamide, vincristine sulfate, methotrexate, and prednisone. Radiotherapy is used more for adjuvant purposes. Synthesis of recent studies allows us to reasonably expect 40% relapse-free survival at 10 years and the establishment of a cure plateau in the near future

    2014-01-01

    Full Text Available Introduction. Primary lymphoma of the gallbladder is an extremely rare entity with approximately 50 cases reported so far. In many of these cases the presenting symptoms were mimicking symptomatic gallstone disease and the diagnosis was made postoperatively, especially when the preoperative imaging results were far from suspicious for malignant disease. Patients and Methods. We report a case of primary lymphoma of the gallbladder in an 85-year-old man with gallstone disease, who was admitted for elective cholecystectomy 2 months after an episode of acute cholecystitis and pancreatitis. Histological evaluation of the specimen revealed a small lymphocytic lymphoma of the gallbladder. This type of primary gallbladder lymphoma has not been previously reported. Discussion. The most common primary lymphomas of the gallbladder are MALT lymphomas and diffuse large B-cell lymphomas, although a variety of other histological types have been reported. The association of these lesions with chronic inflammation is the most convincing theory for their pathogenesis. For lesions confined to the gallbladder, cholecystectomy is considered to be sufficient, while supplementary chemotherapy significantly improves prognosis in more advanced disease.

    Cleft lip and palate (CLP) affects the dentoalveolar and nasolabial facial regions. Internal and external nasal dysmorphology may persist in individuals born with CLP despite surgical interventions. 7-18 year old individuals born with unilateral and bilateral CLP (n = 50) were retrospectively assessed using cone beam computed tomography. Anterior, middle, and posterior nasal airway volumes were measured on each facial side. Septal deviation was measured at the anterior and posterior nasal spine, and the midpoint between these two locations. Data were evaluated using principal components analysis (PCA), multivariate analysis of variance (MANOVA), and post-hoc ANOVA tests. PCA results show partial separation in high dimensional space along PC1 (48.5% variance) based on age groups and partial separation along PC2 (29.8% variance) based on CLP type and septal deviation patterns. MANOVA results indicate that age (P = 0.007) and CLP type (P ≤ 0.001) significantly affect nasal airway volume and septal deviation. ANOVA results indicate that anterior nasal volume is significantly affected by age (P ≤ 0.001), whereas septal deviation patterns are significantly affected by CLP type (P ≤ 0.001). Age and CLP type affect nasal airway volume and septal deviation patterns. Nasal airway volumes tend to be reduced on the clefted sides of the face relative to non-clefted sides of the face. Nasal airway volumes tend to strongly increase with age, whereas septal deviation values tend to increase only slightly with age. These results suggest that functional nasal breathing may be impaired in individuals born with the unilateral and bilateral CLP deformity. © 2014 Wiley Periodicals, Inc.

    2015-01-01

    Nasal drug delivery has now been recognized as a promising route for drug delivery due to its capability of transporting a drug to systemic circulation and central nervous system. Though nasal mucosa offers improved bioavailability and quick onset of action of the drug, main disadvantage associated with nasal drug delivery is mucocilliary clearance due to which drug particles get cleared from the nose before complete absorption through nasal mucosa. Therefore, mucoadhesive polymeric approach can be successfully used to enhance the retention of the drug on nasal mucosal surface. Here, some of the aspects of the stimuli responsive polymers have been discussed which possess liquid state at the room temperature and in response to nasal temperature, pH and ions present in mucous, can undergo in situ gelation in nasal cavity. In this review, several temperature responsive, pH responsive and ion responsive polymers used in nasal delivery, their gelling mechanisms have been discussed. Smart polymers not only able to enhance the retention of the drug in nasal cavity but also provide controlled release, ease of administration, enhanced permeation of the drug and protection of the drug from mucosal enzymes. Thus smart polymeric approach can be effectively used for nasal delivery of peptide drugs, central nervous system dugs and hormones.

    The nose is the most frequently traumatized portion of the human face. High-speed motor vehicle accidents and interpersonal violence commonly produce bony pyramid and septal damage and occasional minor soft-tissue damage. Major soft-tissue injuries are much less commonly encountered. Avulsion injuries of this type may involve skin only or the bony and cartilaginous framework as well. The severity of these injuries can range from total avulsion to minor skin loss and anywhere within the spectrum between. My experience is reviewed, management guidelines and options are detailed, and selected cases are presented.

    Histological transformation of follicular lymphoma (FL) to a more aggressive non-Hodgkin's lymphomas is a pivotal event in the natural history of FL and is associated with poor outcome. While commonly observed in clinical practice and despite multiple studies designed to address its pathogenesis, the biology of this process represents an enigma. In this chapter we present a state of the art review summarizing the definition of histologic transformation, its incidence, pathogenesis, clinical manifestations, treatment and outcome. Furthermore, we specifically emphasize gaps in our knowledge that should be addressed in future studies. PMID:21658615

    With approximately 10000 cases per year in France, non-Hodgkin's lymphoma (NHL) represents the most frequent hematological malignancy, and 5 to 10 % of new cases of cancers. NHLs constitute a heterogeneous group of lympho-proliferative diseases, including entities with very different epidemiological and evolutive characteristics, as well as prognosis and treatments. Several classifications exist, but in practice, we individualize aggressive NHL including Diffuse Large B-Cell Lymphomas (DLBCL) which is the most common lymphoma, and indolent NHL including follicular lymphomas and mucosa-associated lymphoid tissue (MALT) lymphomas. The role of the radiotherapy in the management of NHLs varies according to the specific sub-type of lymphoma, but it has become increasingly limited over time. Overall it finds indications with curative intent only in situations of localized LMNH: either associated with chemotherapy as part of a combined modality therapy as for the treatment of localized DLBCL, or as exclusive treatment specially in the rare situations of localized follicular lymphomas. Moreover, lymphocytes being extremely radiosensitive cells, radiotherapy retains excellent indications with palliative intent for the management of symptomatic bulky tumor masses, and that whatever the sub-type of NHLs may be. It is important to remember that even today the 'Involved Field' irradiation type remains the gold standard for the treatment of nodal NHLs, even if we witness at present the emergence of new types of irradiation, which aim to reduce the amount of irradiated tissues to try to limit the risks of delayed radio-induced complications. The purpose of this article is to clarify the specific aspects (epidemiological, radio-anatomical and prognostic characteristics) of each NHLs'sub-types (except primary central nervous system lymphomas), as well as the practical modalities of the irradiation (illustrated by a clinical case record) when an indication of

    Full Text Available Primary nasal tuberculosis is a rare disease with nearly 40 cases reported. Our patient was a young male presented with left sided nasal obstruction, anosmia and occasional epistaxis for last 7 weeks after 6 months of blunt trauma nose. Contrast enhanced computed tomography of the para nasal sinuses showed increased soft-tissue density with contrast enhancement in the left maxillary antrum with extension through left osteomeatal foramen to the left nasal cavity along with further extension through choana to nasopharynx resulting in partial obliteration of the nasopharyngeal airway. Nasal endoscopy revealed a sessile polypoidal pinkish mass arising from the left osteomeatal foramen. Histopathological examination of excisional biopsy of that area showed caseating granuloma. Our patient diagnosed as primary nasal tuberculosis following trauma and treated with anti-tubercular chemotherapy.

    2016-01-01

    Spindle Cell Carcinoma (SpCC), also known as Sarcomatoid Carcinoma, is a rare and peculiar biphasic malignant neoplasm that occurs mainly in the upper aero-digestive tract, mostly in larynx. SCC accounts for 3% of all squamous cell carcinomas (SCCs) in the head and neck region. It is a rare variant of SCC which shows spindled or pleomorphic tumour cells simulating a true sarcoma. We present a case report of SpCC nasal cavity in a 50-year-old female patient, presented with intermittent epistaxis from left nasal cavity. On physical examination, the patient had an ulcero-exophytic type of mass in the left nasal cavity and a smooth bulge on the left side of anterior hard palate. Patient underwent excision of nasal mass along with partial palatectomy by facial degloving approach and reconstruction of palate with naso-labial flap. The postoperative histopathological report showed SCC. Surgery forms the mainstay of treatment. Radiotherapy and Chemotherapy is warranted in order to improve treatment results. As only few cases have been reported, we report a case of this rare entity to contribute for better understanding and awareness of this rare malignancy. PMID:27190843

    2005-03-01

    Nasal trigeminal chemosensitivity in mice and rats is mediated in part by solitary chemoreceptor cells (SCCs) in the nasal epithelium (Finger et al., 2003). Many nasal SCCs express the G-protein alpha-gustducin as well as other elements of the bitter-taste signaling cascade including phospholipase Cbeta2, TRPM5 and T2R bitter-taste receptors. While some populations of sensory cells are replaced throughout life (taste and olfaction), others are not (hair cells and carotid body chemoreceptors). These experiments were designed to test whether new SCCs are generated within the epithelium of adult mice. Wild type C57/B6 mice were injected with the thymidine analog 5-bromo-2'-deoxyuridine (BrdU) to label dividing cells. At various times after injection (1-40 days), the mice were perfused with 4% paraformaldehyde and prepared for dual-label immunocytochemistry. Double labeled cells were detected as early as 3 days post BrdU injection and remained for as long as 12 days post-injection suggesting that SCCs do undergo turnover like the surrounding nasal epithelium. No BrdU labeled cells were detected after 24 days suggesting relatively rapid replacement of the SCCs.

    Various case reports on nasal myiasis written during the 1990s and 2000s state that nasal myiasis, which is known as peenash among South Asian natives, is a form of divine punishment in Hindu mythology, but do not provide citations from Hindu scriptures that would suggest this interpretation. This paper aims to discuss the phenomenon of peenash in a historical context by examining medical literature written during the nineteenth and early twentieth centuries, to identify Hindu texts contributing to the belief of some Hindus that nasal myiasis is a form of divine punishment, and to provide an overview of contemporary treatment for and management of nasal myiasis.

    2017-05-01

    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.

    We have investigated the effects of low-frequency pulsed electromagnetic field (LF-EMF) produced by BEMER device on experimental mouse T-cell lymphoma EL4 growing on conventional and/or athymic (nude) mice. Exposure to EMF-BEMER slowed down the growth of tumor mass and prolonged the survival of experimental animals. The effect was more pronounced in immuno-compromised nude mice compared to conventional ones. Acceleration of tumor growth was never observed. No measurable levels of Hsp 70 or increased levels of specific anti-EL4 antibodies were detected in the serum taken from experimental mice before and at different intervals during the experiment, i.e. before solid tumor appeared, at the time of its aggressive growth, and at the terminal stage of the disease. A significant synergizing antitumor effect was seen when EL4 tumor-bearing mice were simultaneously exposed to EMF-BEMER and treated with suboptimal dose of synthetic HPMA copolymer-based doxorubicin, DOX(HYD)-HPMA. Such a combination may be especially useful for heavily treated patients suffering from advanced tumor and requiring additional aggressive chemotherapy which, however, at that time could represent almost life-threatening way of medication.

    Benzalkonium chloride is a preservative commonly used in nasal decongestant sprays. It has been suggested that benzalkonium chloride may be harmful to the nasal mucosa. Decongestion with the vasoconstrictor xylometazoline containing benzalkonium chloride has been shown to cause a significant reduction of the nasal mucosal temperature. The purpose of the present study was to determine the short-term influence of xylometazoline nasal spray with and without benzalkonium chloride on the nasal mucosal temperature. Healthy volunteers (30) were included in the study. Fifteen volunteers received xylometazoline nasal spray (1.0 mg/mL) containing benzalkonium chloride (0.1 mg/mL) and 15 age-matched subjects, received xylometazoline nasal spray without benzalkonium chloride. Using a miniaturized thermocouple the septal mucosal temperature was continuously measured at defined intranasal detection sites before and after application of the nasal spray. The mucosal temperature values did not significantly differ between the group receiving xylometazoline containing benzalkonium chloride and the group receiving xylometazoline spray without benzalkonium chloride before and after decongestion (P > 0.05). In both study groups septal mucosal temperatures significantly decreased after decongestion (P reduction of the nasal mucosal blood flow following vasoconstriction. This study indicates that benzalkonium chloride itself does not seem to influence nasal blood flow and nasal mucosal temperature in topical nasal decongestants.

    While the cellular origin of lymphoma is often characterized by chromosomal translocations and other genetic aberrations, its growth and development into a malignant neoplasm is highly dependent upon its ability to escape natural host defenses. Neoplastic cells interact with a variety of non-malignant cells in the tumor milieu to create an immunosuppressive microenvironment. The resulting functional impairment and dysregulation of tumor-associated immune cells not only allows for passive growth of the malignancy but may even provide active growth signals upon which the tumor subsequently becomes dependent. In the past decade, the success of immune checkpoint blockade and adoptive cell transfer for relapsed or refractory lymphomas has validated immunotherapy as a possible treatment cornerstone. Here, we review the mechanisms by which lymphomas have been found to evade and even reprogram the immune system, including alterations in surface molecules, recruitment of immunosuppressive subpopulations, and secretion of anti-inflammatory factors. A fundamental understanding of the immune evasion strategies utilized by lymphomas may lead to better prognostic markers and guide the development of targeted interventions that are both safer and more effective than current standards of care

    Nasal hyper-reactivity is an increased sensitivity of the nasal mucosa to various nonspecific stimuli. Both allergic rhinitis (AR) and nonallergic rhinitis (NAR) patients can elicit nasal hyper-reactivity symptoms. Differences in the prevalence or type of nasal hyper-reactivity in AR and NAR patients are largely unknown. In this study, we quantitatively and qualitatively assessed nasal hyper-reactivity in AR and NAR. In the first part, an analysis of a prospectively collected database was performed to reveal patient-reported symptoms of hyper-reactivity. In the second part, cold dry air provocation (CDA) was performed as a hyper-reactivity measure in AR and NAR patients and healthy controls, and symptoms scores, nasal secretions and peak nasal inspiratory flow were measured. Comparisons were made between AR and NAR patients in both studies. The database analysis revealed high hyper-reactivity prevalence in AR (63.4%) and NAR (66.9%). There were no differences between AR and NAR in terms of the number or type of hyper-reactivity stimuli. Hyper-reactivity to physical stimuli did not exclude a response to chemical stimuli, or vice versa. CDA provocation resulted in a significant increase in rhinitis symptoms and the amount of nasal secretions in AR and NAR patients, but not in controls. We found no quantitative or qualitative differences in nasal hyper-reactivity between AR and NAR patients. It is not possible to differentiate NAR subpopulations based on physical or chemical stimuli. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Rituximab is a chimeric mouse-human antibody that targets the CD20 antigen, which is found in both normal and neoplastic B cells. In recent years, it has been increasingly used to treat cutaneous B-cell lymphoma and is now considered an alternative to classic treatment (radiotherapy and surgery) of 2 types of indolent lymphoma, namely, primary cutaneous follicle center lymphoma and primary cutaneous marginal zone B-cell lymphoma. Rituximab is also administered as an alternative to polychemotherapy in the treatment of primary cutaneous large B-cell lymphoma, leg type. Its use as an alternative drug led to it being administered intralesionally, with beneficial effects. In the present article, we review the literature published on the use of rituximab to treat primary cutaneous B-cell lymphoma. Copyright © 2012 Elsevier España, S.L. and AEDV. All rights reserved.

    Full Text Available Background: Nasal biometrics is vital to facial analyses. This study evaluated nasal biometrics in Hausas and Yorubas of Nigeria. Materials and Methods: Hausas (150 males and 150 females, aged 18-36 years and Yorubas (150 males and 150 females, aged 15-33 years were selected as subjects with informed consents and when established as Hausas or Yorubas by parents and grandparents. Height, body weight and cephalometric parameters (evaluated on three-dimensional facial photographs were measured on subjects. The novel Akinlolu-Raji image-processing algorithm was developed using modified row method of computer programming. Nasal root width, nose height, nose width, nasal bridge length, nasal tip protrusion, nasal index, facial width and nasofacial proportion computed from readings of Akinlolu-Raji image-processing algorithm were analyzed using Z-test (P ≤ 0.05 of 2010 Microsoft Excel statistical software. Results: Computed nasal biometrics showed statistically nonsignificant higher values (P > 0.05 in males of Hausas (100% and Yorubas (80% compared to their female counterparts. In addition, results showed nonsignificant higher values (P > 0.05 in 80% of nasal biometrics in Hausas compared to Yorubas in both sexes. Based on classifications of nose types from nasal index, Hausas have the platyrrhine nose type while Yorubas have the mesorrhine nose type. Nasofacial proportion was lower in Hausa males compared to females, but of same values in Yoruba males and females. In addition, nasofacial proportions were lower in Hausas compared to Yorubas in both sexes. Conclusions: Sexual dimorphism of nasal biometrics exists between sexes of Hausas and Yorubas. Furthermore, Hausas and Yorubas are of similar nasal sizes.

    Nonisotonic aerosol may act as a provocation agent in the upper and lower airways of hyperreactive individuals. The purpose of the study was to compare the results of nasal challenge with distilled water in patients with allergic rhinitis to those with noninfective nonallergic rhinitis (NINAR), with respect to the potential clinical use of the obtained data. A group of 68 ambulatory patients with allergic rhinitis or NINAR (39 perennial allergic, 6 seasonal, 23 NINAR) were challenged with 10 mL of distilled water aerosol after the baseline active anterior rhinomanometry. Patients with nasal polyposis at endoscopy, significant unilateral septal deviation, positive bacteriologic swab, recent nasal surgery, and uncertain anamnestic data about the medication taken 6 weeks before the provocation were excluded from the study. After 10 minutes of nasal provocation, rhinomanometry was repeated to assess the response. In 15 patients of the perennial allergic group, the same measurements were performed after a 2-week oral antihistamine and topical steroid therapy. Nasal resistance was significantly increased on the more patent side of the nose after nasal provocation with distilled water aerosol in allergic patients in comparison to the nasal resistance before provocation. In the patients with NINAR, the provocation resulted in a significant rise on the more patent side, but the total nasal airway resistance (NAR) levels were also significantly increased. The systemic antihistamine and topical steroid 2-week therapy in patients with perennial allergic rhinitis significantly reduced the response to nasal distilled water provocation. Nasal provocation with distilled water aerosol is a cheap, simple, and acceptable method that provides useful clinical data on the level of nonspecific nasal hyperreactivity and the therapy success.

    Infants born prematurely with respiratory distress syndrome are at high risk for complications from mechanical ventilation. Strategies are needed to minimize their days on the ventilator. The purpose of this study was to compare extubation success rates in infants treated with 2 different types of continuous positive airway pressure devices. A retrospective cohort study design was used. Data were retrieved from electronic medical records for patients in a large, metropolitan, level III neonatal intensive care unit. A sample of 194 premature infants with respiratory distress syndrome was selected, 124 of whom were treated with nasal intermittent positive pressure ventilation and 70 with bi-level variable flow nasal continuous positive airway pressure (bi-level nasal continuous positive airway pressure). Infants in both groups had high extubation success rates (79% of nasal intermittent positive pressure ventilation group and 77% of bi-level nasal continuous positive airway pressure group). Although infants in the bi-level nasal continuous positive airway pressure group were extubated sooner, there was no difference in duration of oxygen therapy between the 2 groups. Promoting early extubation and extubation success is a vital strategy to reduce complications of mechanical ventilation that adversely affect premature infants with respiratory distress syndrome.

Two bilateral nasal allergen provocations were performed in a group of 26 pollen-sensitive volunteers. Acoustic rhinometry measurements were taken during the nasal cycle, and then after the provocation. A cross-sectional area at the level of the inferior turbinate (CSA-2 was measured. Consecutive challenges were performed in the opposite phase of the nasal cycle: the side which had been wide just before the first challenge, was narrow before the second provocation. results. Asymmetry in CSA-2 reduction between the nasal passages was observed in most cases. Significant difference was observed between mean CSA-2 reduction rate (reactivity of the side that responded with greater congestion, and the opposite side. No significant difference was found in mean CSA-2 reduction rate between the side which was narrow, and the side which was wide before provocation. conclusions. Asymmetry of congestive response during bilateral nasal allergen provocation is not dependent on the stage of the nasal cycle preceding the challenge.

    Therapy for non-Hodgkin lymphoma has benefited greatly from basic science and clinical research such that chemotherapy and monoclonal antibody therapy have changed some lymphoma subtypes from uniformly lethal to curable, but the majority of lymphoma patients remain incurable. Novel therapies with less toxicity and more specific targeting of tumor cells are needed and immunotherapy is among the most promising of these. Recently completed randomized trials of idiotype vaccines and earlier-phase trials of other vaccine types have shown the ability to induce antitumor T cells and some clinical responses. More recently, trials of adoptive transfer of antitumor T cells have demonstrated techniques to increase the persistence and antitumor effect of these cells. Herein, we discuss lymphoma immunotherapy clinical trial results and what lessons can be taken to improve their effect, including the combination of vaccination and adoptive transfer in an approach we have dubbed ‘immunotransplant’.

    A study has been carried out to assess the mucociliary function of nasal mucosa in 30 patients: 16 had undergone surgery due to larynx malignancy and the remaining 14 were divided in two groups. The first group was composed of seven patients suffering from larynx cancer but not operated, and the second group of seven had pathology not related to the airways (control group). The method used a sup(99m)technetium sulphur colloid drop deposited on the nasal mucosa of one nostril. To calculate the rate of transport, a new method of quantification has been introduced, based on the formation of a parametric image. The mean velocity in laryngectomees was 3.6 mm/min (range 1.1-6.4). It was compared with the group of 14 patients without tracheostomy (mean 5.3, range 3.3-8.2). An impaired student's-t-test gave a significant difference between both groups (P<0.005). The comparison between patients with nonoperated larynx cancer and normals have a nonsignificant difference. The 16 operated patients were arbitrarily divided into two groups as per the time elapsed from laryngectomy; seven were studied within the first 3 years of operation and seven other patients after this term. The comparison between them was not significant. (orig.)

    Esthesioneuroblastoma is an uncommon cancer of the nasal cavity. We describe the outcomes for 26 patients treated with curative intent with photon radiotherapy (RT) at the University of Florida. Between May 1972 and June 2007, 26 patients received RT for previously untreated esthesioneuroblastoma of the nasal cavity. Sixteen patients were males and 10 were females with a median age of 55 years (range, 3 to 82 y). The modified Kadish stage distribution was: B, 7 patients; C, 17 patients; and D, 2 patients. Treatment modalities included the following: definitive RT, 5 patients; preoperative RT, 2 patients; and postoperative RT after resection, 19 patients. Elective neck irradiation (ENI) was performed in 17 (71%) of 24 N0 patients. Rates of local control, cause-specific survival, and absolute overall survival at 5 years were 79%, 72%, and 69%, respectively. Overall survival among patients treated with definitive RT was 20% at 5 years, compared with 81% among those who underwent surgery and adjuvant RT (P=0.01). One (6%) of 17 patients who received ENI developed a recurrence in the neck and was successfully salvaged. Ultimate neck control was 100% at 5 years for patients who received ENI versus 69% among those not receiving ENI (P=0.0173). Resection combined with adjuvant RT is more effective than surgery or RT alone in the treatment of esthesioneuroblastoma. ENI reduces the risk of regional relapse in patients with Kadish stage B and C cancers.

    Here, we give an updated overview of the subtype distribution of lymphomas in East Asia and also present the genome sequencing data on two major subtypes of these tumors. The distribution of lymphoma types/subtypes among East Asian countries is very similar, with a lower proportion of B-cell malignancies and a higher proportion of T/natural killer (NK)-cell lymphomas as compared to Western populations. Extranodal NK/T-cell lymphoma is more frequently observed in East Asia, whereas follicular lymphoma and chronic lymphocytic leukemia, are proportionally lower. The incidence rate of lymphoma subtypes in Asians living in the US was generally intermediate to the general rate in US and Asia, suggesting that both genetic and environmental factors may underlie the geographical variations observed.Key cancer driver mutations have been identified in Asian patients with diffuse large B-cell lymphoma or extranodal NK/T-cell lymphoma through genome sequencing. A distinct somatic mutation profile has also been observed in Chinese diffuse large B-cell lymphoma patients. The incidence and distribution of lymphoma subtypes differed significantly between patients from East Asia and Western countries, suggesting subtype-specific etiologic mechanisms. Further studies on the mechanism underlying these geographical variations may give new insights into our understanding of lymphomagenesis.

  13. Genome sequencing and analysis reveals possible determinants of Staphylococcus aureus nasal carriage

    2008-09-01

    Full Text Available Abstract Background Nasal carriage of Staphylococcus aureus is a major risk factor in clinical and community settings due to the range of etiologies caused by the organism. We have identified unique immunological and ultrastructural properties associated with nasal carriage isolates denoting a role for bacterial factors in nasal carriage. However, despite extensive molecular level characterizations by several groups suggesting factors necessary for colonization on nasal epithelium, genetic determinants of nasal carriage are unknown. Herein, we have set a genomic foundation for unraveling the bacterial determinants of nasal carriage in S. aureus. Results MLST analysis revealed no lineage specific differences between carrier and non-carrier strains suggesting a role for mobile genetic elements. We completely sequenced a model carrier isolate (D30 and a model non-carrier strain (930918-3 to identify differential gene content. Comparison revealed the presence of 84 genes unique to the carrier strain and strongly suggests a role for Type VII secretion systems in nasal carriage. These genes, along with a putative pathogenicity island (SaPIBov present uniquely in the carrier strains are likely important in affecting carriage. Further, PCR-based genotyping of other clinical isolates for a specific subset of these 84 genes raise the possibility of nasal carriage being caused by multiple gene sets. Conclusion Our data suggest that carriage is likely a heterogeneic phenotypic trait and implies a role for nucleotide level polymorphism in carriage. Complete genome level analyses of multiple carriage strains of S. aureus will be important in clarifying molecular determinants of S. aureus nasal carriage.

    The aim of this study was to describe an outbreak of Burkholderia stabilis colonization among patients in a nasal ward. Multilocus sequence typing (MLST) was used for the molecular typing of B. stabilis isolates. Microbiological records were reviewed to delineate the colonization outbreak period. One hundred seventy-one cultures of environment and equipment samples from the nasal ward were performed to trace the source of contamination. Infection control measures were taken in order to end the outbreak. All B. stabilis isolates were identified as a new MLST type, ST821. A total of 53 patients carried this B. stabilis in the nasal ward between March and September 2013, which was defined as the outbreak period. The source of the colonization was not determined because all environment cultures were negative for Burkholderia cepacia complex. No further B. stabilis carriers have been found in the ward since the implementation of interventions. Attention must be paid to asymptomatic colonization in order to identify outbreaks early.

    Purpose: As scarce information is available, in this research we have tried to describe the imaging findings of the Burkitt's lymphoma. Retrospective analysis of the clinical and imaging presentation of a 4 years old boy, is given. Biopsy confirmed the BL. Different imaging techniques were combined. The X-rays were negative. The US revealed a moderate hepatomegaly with multiple hypoechoic nodules and free fluid in the abdominal cavity. The CT showed the hepatomegaly as well as solid nodules in great number and different sizes(due to the densitometric behaviour and to post contrast enhancement), a scarce amount of ascites and a density increase of the mesentery fat. The MRI characterized and revealed in detail the US and the CT findings. The Burkitt's lymphoma is a rare entity; several methods are needed to approach the diagnosis. It represents a great clinical and imaging challenge. (author)

    Primary gastric lymphomas are the most common extra nodal lymphomas. They can be presented as aggressive or indolent, majority of indolent lymphomas are associated to H. pylori infection. The basic diagnostic procedures are endoscopy, endo sonography and biopsy of gastric tissue. Therapy is related to the histological subtype, stage, H. pylori positivity, clinical symptoms and condition of patient. The aim of the treatment is remission as well as good quality of life. The prognosis of patients with primary gastric lymphomas is relatively good. (author)

    Human T-cell lymphoma/leukemia virus (HTLV)-1 is a retrovirus transmitted vertically from mother to child parenterally and sexually by infected lymphocytes. The objective of this study was to determine the seroprevalence of HTLV-1 antibodies and associated risk factors for HTLV-1 infection among pregnant women in University of Nigeria Teaching Hospital, Enugu, southeast Nigeria. A cross-sectional study was carried out from July to October 2010. Two hundred pregnant women were recruited consecutively from the antenatal clinic. Five milliliters of blood was collected from each of the participants into a plain sterile bottle and allowed to clot. The serum obtained was stored at -20°C until required for analysis. The serum samples were then analyzed for antibodies to HTLV-1 using a one-step incubation double-antigen sandwich enzyme-linked immunosorbent assay kit. Participants' demographic characteristics and degree of exposure to the risk factors associated with HTLV-1 infection were captured using a questionnaire. Statistical analysis of results was done using SPSS version 17. The average age of the pregnant women was 28.94 years (standard deviation 4.17). The age-group with the highest representation was those between the ages of 26 and 30 years. Thirty-six percent of the population was above 30 years old. The result of the tests showed that only one respondent, a 31-year-old pregnant woman tested positive for HTLV-1 antibodies. Therefore, the seroprevalence of HTLV-1 antibodies among pregnant women attending the antenatal clinic at University of Nigeria Teaching Hospital was 0.5%, with a 95% confidence interval of 0%-2.8%. Some of the sociodemographic risk factors of HTLV-1 infection found to be applicable to the 31-year-old woman who tested positive included positive history of previous sexually transmitted diseases, high parity, low socioeconomic status, female sex, and age above 30 years. The pregnant women that participated in this study were exposed to risk

    There have been sporadic reports about synchronous as well as metachronous gastric adenocarcinoma and primary gastric lymphoma. Many reports have dealt with metachronous gastric adenocarcinoma in mucosa-associated lymphoid tissue lymphoma of stomach. But to our knowledge, there have been no reports that document the increased incidence of metachronous gastric adenocarcinoma in patients with gastric diffuse large B-cell lymphoma. This retrospective study was conducted to estimate the incidence of metachronous gastric adenocarcinoma after primary gastric lymphoma treatment, especially in diffuse large B-cell lymphoma. The retrospective cohort study of 139 primary gastric lymphoma patients treated with radiotherapy at our hospital. Mean observation period was 61.5 months (range: 3.7-124.6 months). Patients profile, characteristics of primary gastric lymphoma and metachronous gastric adenocarcinoma were retrieved from medical records. The risk of metachronous gastric adenocarcinoma was compared with the risk of gastric adenocarcinoma in Japanese population. There were 10 (7.2%) metachronous gastric adenocarcinoma patients after treatment of primary gastric lymphomas. It was quite high risk compared with the risk of gastric carcinoma in Japanese population of 54.7/100,000. Seven patients of 10 were diffuse large B-cell lymphoma and other 3 patients were mixed type of diffuse large B-cell lymphoma and mucosa associated lymphoid tissue lymphoma. Four patients of 10 metachronous gastric adenocarcinomas were signet-ring cell carcinoma and two patients died of gastric adenocarcinoma. Metachronous gastric adenocarcinoma may have a more malignant potential than sporadic gastric adenocarcinoma. Old age, Helicobacter pylori infection and gastric mucosal change of chronic gastritis and intestinal metaplasia were possible risk factors for metachronous gastric adenocarcinoma. There was an increased risk of gastric adenocarcinoma after treatment of primary gastric lymphoma

    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.

    We review here 3 cases of primary thyroid lymphoma that we experienced during the past 5 years (age range: 39-55, all of the patients were female). The clinical and various ultrasonographic characteristics together with the other imaging modalities of primary thyroid lymphomas are described. The clinical features at presentation for one patient were a goiter with rapid growth and this was accompanied by compressive symptoms. The tumors of the other 2 patients were incidentally found during screening thyroid ultrasound exams. The pathologic studies of 2 cases showed a diffuse B-cell lymphoma with associated Hashimoto's thyroiditis and one case was a B-cell lymphoma of the MALT type. An extra-thyroid extension was shown in one case. The treatments included surgery alone for two cases, and chemotherapy and radiation therapy for one case. A US exam of thyroid lymphoma can show various morphological features, and US-CNB is helpful for diagnosing thyroid lymphoma.

    BACKGROUND: Non-Hodgkin lymphoma has increased in frequency over the past 30 years, and is a common cancer in HIV-1-infected patients. Although no definite risk factors have emerged, a viral cause has been postulated. Polyomaviruses are known to infect human beings and to induce tumours in laboratory animals. We aimed to identify which one of the three polyomaviruses able to infect human beings (simian virus 40 [SV40], JC virus, and BK virus) was associated with non-Hodgkin lymphoma. METHODS: We analysed systemic non-Hodgkin lymphoma from 76 HIV-1-infected and 78 HIV-1-uninfected patients, and non-malignant lymphoid samples from 79 HIV-1-positive and 107 HIV-1-negative patients without tumours; 54 colon and breast carcinoma samples served as cancer controls. We used PCR followed by Southern blot hybridisation and DNA sequence analysis to detect DNAs of polyomaviruses and herpesviruses. FINDINGS: Polyomavirus T antigen sequences, all of which were SV40-specific, were detected in 64 (42%) of 154 non-Hodgkin lymphomas, none of 186 non-malignant lymphoid samples, and none of 54 control cancers. This difference was similar for HIV-1-infected patients and HIV-1-uninfected patients alike. Few tumours were positive for both SV40 and Epstein-Barr virus. Human herpesvirus type 8 was not detected. SV40 sequences were found most frequently in diffuse large B-cell and follicular-type lymphomas. INTERPRETATION: SV40 is significantly associated with some types of non-Hodgkin lymphoma. These results add lymphomas to the types of human cancers associated with SV40.

    Full Text Available It has recently been shown that vascular endothelial growth factor (VEGF enhances vascular permeability and that mast cells produce VEGF, suggesting the involvement of VEGF in allergic diseases. In the present study we quantitatively analyzed VEGF in the nasal lavage fluid of patients with nasal allergy. We performed nasal antigen challenge with Japanese cedar pollen antigen in 10 healthy adult volunteers and in 10 cedar pollen IgE-positive patients with nasal allergy. In all patients with nasal allergy, VEGF and histamine levels in the nasal lavage fluid reached a peak 30 min after antigen challenge, then returned to prechallenge values 2 h after antigen challenge. In these patients, the histamine level increased three-fold, while the VEGF level increased 10-fold. However, in all healthy adult volunteers, VEGF and histamine levels did not increase. A stronger correlation was noted between the ratio of decreased nasal cavity volume and the ratio of increased VEGF levels (R = 0.823; P < 0.001 than between the ratio of nasal cavity volume and the ratio of increased histamine levels (R = 0.660; P < 0.01. These results suggest that VEGF may contribute to the pathogenesis of nasal obstruction in the early phase of nasal allergy as a new factor involved in increasing vascular permeability.

    Purpose: A retrospective review analyzed the survival and freedom from relapse of patients with stage IE or IIE primary cutaneous lymphoma (non mycosis fungoides) after treatments with radiation therapy alone (XRT), chemotherapy alone (RX) or combined modality therapy (CMT). Methods and Materials: Fifty two patients with stage IE-IIE cutaneous lymphoma treated at Stanford University Hospital were reviewed. The median age was 57, with a range of 26 to 94 and a male to female ratio of 1.21:1. Patients were staged according to the Ann Arbor System. Pathology was classified according to the Working Formulation. Treatment outcomes were compared using Kaplan-Meier survival curves with a Gehan p-value test. Results: The follow up range was 6 months to 22 years (median 7 years.) Twenty one percent of patients had low grade, 63% had intermediate grade and 15% had high grade lymphoma. The most common histologic subtype was diffuse large cell lymphoma Thirty two patients received radiation alone as initial treatment and sixteen patients received combined modality as initial treatment. Four patients received chemotherapy alone. The only significant prognostic factor for survival was the stage at diagnosis. Patients with stage IE disease had a longer actuarial survival (5-yr=79%, 10-yr=71%), as compared to those with stage IIE (5-yr=49%, 10-yr=33%), (p=0.029). The only significant prognostic factor for freedom from relapse was the initial treatment. Initial combined modality treatment lead to a longer freedom from relapse compared to patients treated with radiation alone (p=0.002), (median 5 years vs. 1.2 years). Despite this, the actuarial overall survival in the combined modality group and the radiation alone group are similar (median survival 7.7 and 8 years). The efficacy of either radiation or chemotherapy as salvage treatment after radiation failure was equivalent and both salvage treatments lead to equally long survival and freedom from second relapse.

    Improvements in the classification, staging, and treatment of the lymphomas, complemented by an improved understanding of the biology of these diseases, has led to an improved outcome of therapy for both Hodgkin's disease and many of the non-Hodgkin's lymphomas. The rapid changes that have occurred in this field in the last decade make it timely to review this subject for radiation oncologists in a comprehensive fashion. This course is designed to meet broad educational needs required for understanding these diseases and providing effective care for patients with lymphoma. The faculty includes many leaders from both laboratory and clinical disciplines dealing with lymphomas, who will address a variety of scientific and clinical topics. The morning session will be devoted to Hodgkin's disease, including new concepts in its biology, a review of clinical trials for early stage disease, a discussion of the role of high dose therapy, and description of long term complications of treatment. The afternoon sessions will be devoted to the non-Hodgkin's lymphomas, including new concepts in pathology and biology, a description of specific entities including the low grade lymphomas, MALT lymphomas, extranodal lymphomas, intermediate grade lymphomas, mantle cell lymphomas, and summary discussions of the role of radioimmuno-therapy and high dose therapy. Although the role of radiation therapy in the management of patients with lymphoma has changed dramatically in the past two decades, radiation remains the most effective single agent for the treatment of these diseases and it is especially important for radiation onologists to keep abreast of these new concepts. This course has been designed to achieve that goal

    To report an unusual location of infrasellar craniopharyngioma in a peadiatric patient. A six-year-old boy presented with persistent bilateral nasal obstruction for one year. Clinical examination revealed a posterior choanal mass arising from septum and the finding was confirmed by paranasal sinuses computed tomography scan. He then underwent wide local excision. Histopathological examination confirmed the diagnosis of craniopharyngioma (adamantinomatous type). There were no signs and symptoms of recurrence after a year of followup. Infracranial craniopharyngioma without sellar involvement is extremely rare. Persistent nasal obstruction without endocrine dysfunction is the common presentation. Radiological imaging is important to diagnose and assess the extent. The mainstay of treatment for infrasellar craniopharyngioma is surgery. Regular follow up is mandatory.

    Anaplastic large cell lymphoma (ALCL) is a rare type of nonHodgkin's lymphoma (NHL), but one of the most common subtypes of T-cell lymphoma. It is an aggressive T-cell lymphoma, and some ALCL may mimic less aggressive classical HL histopathlogically. It may be misdiagnosed unless careful immunohistochemical examination is performed. As the prognosis and management of these two lymphomas vary significantly, it is important to make a correct diagnosis. We describe a case who was diagnosed as classical HL by histopathological examination of cervical lymph node, in whom 18 F-flouro deoxyglucose positron emission tomography/computed tomography appearances were unusual for HL and warranted review of histopathology that revealed anaplastic lymphoma kinase-1 negative anaplastic large T-cell lymphoma, Hodgkin-like variant, thereby changing the management

  12. Transformation of marginal zone lymphoma (and association with other lymphomas).

    Casulo, Carla; Friedberg, Jonathan

    Marginal zone lymphomas (MZL) are a diverse group of indolent lymphoproliferative disorders that comprise three subtypes: nodal, splenic and mucosal associated marginal zone lymphomas (MALT). Histologic transformation (HT) to an aggressive lymphoma is a rare event that can occur in any subtype, and at lower frequency compared to other indolent non Hodgkin lymphomas (NHL) like follicular lymphoma. There are few data directly associated with risk and prognosis of transformation in MZL. However, recent advances in the understanding of molecular and genetic features of MALT have contributed to an evolving appreciation of HT in this disease. Optimal treatment of HT of MZL remains unknown. Much of the approach to managing transformed MZL is extrapolated from other indolent NHLs. Copyright © 2016 Elsevier Ltd. All rights reserved.

    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.

  14. New modalities (setting, fractionation) of radioimmunotherapy by 90Y-ibritumomab tiuxetan (90Y zevalin) in first line treatment of follicular type non Hodgkin malignant lymphomas: efficiency, toxicity and personalized dosimetry approach

    Morschhauser, F.

    2008-12-01

    Rationale: radioimmunotherapy (R.I.T.) with 90 Y-ibritumomab tiuxetan ([ 90 Y] Zevalin ) is a new treatment option for patients with relapsed/refractory non Hodgkin follicular lymphoma (F.L.). Efficacy increases when Zevalin is used earlier in the disease course. Currently, Zevalin dosage is based on weight and not dosimetry. This most likely results in a wide range of absorbed dose to critical organs and tumor, which in turn translates in unpredictable efficacy and toxicity. Optimizing R.I.T. with [ 90 Y] Zevalin will require its use as part of first-line therapy and implementation of patient-specific dosimetry methods in clinical trials. Objectives and methods: we have consecutively studied 2 new modalities of using Zevalin in first line therapy of F.L.. First, we conducted an international, randomized, phase 3 trial to evaluate the efficacy and safety of consolidation with Zevalin(15 MBq/Kg) in patients with advanced-stage F.L. achieving at least a partial response after induction immuno chemotherapy. A second approach consisted of evaluating a fractionated schedule with 2 doses of Zevalin (11.1 MBq/kg each), 9 to 13 weeks apart, as front line therapy in F.L. patients with high tumor burden. As part of this second approach, we designed a refined imaging-based (planar and 3-dimensional) dosimetry protocol to improve prediction of dose efficacy and toxicity after each dose of zevalin. Data acquisition was performed in 3 centers (Lille, Nantes and Manchester) while data treatment and specific dose calculations for major organ, tumor masses and bone marrow were centralized. Conclusion: Consolidation of first remission with 90 Y-ibritumomab tiuxetan in advanced-stage follicular lymphoma is highly effective with no unexpected toxicities, prolonging P.F.S. by 2 years and resulting in high P.R.-to-C.R. conversion rates regardless of type of first-line induction treatment. Preliminary data show the feasibility of front line fractionated R.I.T. with Zevalin in patient

    Human T-cell leukemia/lymphoma virus type 1 (HTLV-1) infection can lead to the development of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), concomitantly with or without other inflammatory disorders such as myositis. These pathologies are considered immune-mediated diseases, and it is assumed that migration within tissues of both HTLV-1-infected CD4(+) T cells and anti-HTLV-1 cytotoxic T cells represents a pivotal event. However, although HTLV-1-infected T cells were found in inflamed lesions, the antigenic specificity of coinfiltrated CD8(+) T cells remains to be determined. In this study, we performed both ex vivo and in situ analyses using muscle biopsies obtained from an HTLV-1-infected patient with HAM/TSP and sporadic inclusion body myositis. We found that both HTLV-1-infected CD4(+) T cells and CD8(+) T cells directed to the dominant Tax antigen can be amplified from muscle cell cultures. Moreover, we were able to detect in two successive muscle biopsies both tax mRNA-positive mononuclear cells and T cells recognized by the Tax11-19/HLA-A*02 tetramer and positive for perforin. These findings provide the first direct demonstration that anti-Tax cytotoxic T cells are chronically recruited within inflamed tissues of an HTLV-1 infected patient, which validates the cytotoxic immune reaction model for the pathogenesis of HTLV-1-associated inflammatory disease.

    Full Text Available In the article, the acoustic features of nasals in Standard Latvian are investigated. The aim of the study is to examine whether some of the spectral properties of nasal murmur (namely anti-formant frequency, as well as frequency and bandwidth of the first nasal formant can be considered as efficient cues for distinguishing between nasal places of articulation.Speech recordings from 10 native speakers of Standard Latvian, five male and five female, aged 19–39, without any disorders or dialectal traces in their pronunciation, were used for the analysis. Prevocalic nasals [m; n; ɲ] were analyzed in isolated CVC syllables, where C is one of the nasals and V is one of the vowels [i(ː; e(ː; æ(ː; ɑ(ː; ɔ(ː; u(ː]. The velar [ŋ] — the allophone of the phoneme /n/ — was recorded in postvocalic position in [k]V[ŋks] structure units. 1260 items were analyzed in total.According to the results, the nasals of Standard Latvian can be distinguished by anti-formant frequencies rather efficiently, and the results generally agree with those obtained in previous research of Latvian as well as data reported for other languages. The frequencies and the bandwidths of the first nasal formant are less informative regarding nasal place of articulation and can be used only for distinguishing between [ŋ] and [m; n; ɲ]. Conducting perception tests to assess the auditory relevance of these acoustic features is necessary.

  17. Genetic analysis of radiation-induced mouse thymic lymphomas

    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

    Omalizumab, a monoclonal antibody against IgE, may be effective on nasal polyps, but its use is not currently authorized to treat that disease. We report the cases of three patients who were given omalizumab for asthma after undergoing nasal surgical polypectomy. Although such procedure is frequently followed by polyp recurrence, none of the three patients developed this complication, and in one subject the regression of initial polyp return was registered after starting omalizumab. Our data support the hypothesis that omalizumab may be useful to treat nasal polyposis.

    Full Text Available Angiomatous polyp (Angiectatic nasal polyps is rare and its incidence is 4-5% of all nasal polyps. As it occurs with variable clinical features and there is no confirmatory preoperative investigation, clinical diagnosis can be a dilemma. Clinical picture of angiofibroma, simple antrochoanal polyp and inverted papilloma may resemble with each other. As polyps invade surrounding bone, these should be distinguished from a malignant mass. We present an interesting case of an infarcted angiectatic nasal polyp with extensive surrounding bony destruction. Correct preoperative radiological diagnosis is important to avoid unnecessary extensive surgery. Histopathological evaluation of polyps is mandatory since they require different treatment due to difference in the prognosis.

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.

    Purpose: To review our institutional experience with primary orbital lymphoma and determine the prognostic factors for survival, local control, and distant metastases. In addition, we also analyzed the risk factors for complications in the radiotherapeutic management of this tumor. Methods and Materials: Between 1973 and 1998, 47 patients (29 women [62%] and 18 men [38%], median age 69 years, range 32-89) with Stage IAE orbital lymphoma were treated with curative intent at one department. Five had bilateral orbital involvement. The tumor was located in the eyelid and extraocular muscles in 23 (44%), conjunctiva in 17 (33%), and lacrimal apparatus in 12 (23%). The histologic features according to the World Heath Organization classification of lymphoid neoplasms was follicular lymphoma in 25, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type in 8, diffuse large B-cell lymphoma in 12, mantle cell lymphoma in 6, and peripheral T-cell lymphoma in 1. For the purposes of comparison with the existing literature on orbital lymphomas, the grading system according to the Working Formulation was also recorded. The histologic grade was low in 33 (63%), intermediate in 18 (35%), and high in 1 (2%). All patients were treated with primary radiotherapy alone. The median dose for low-grade tumors was 3000 cGy (range 2000-4020); the median dose for intermediate and high-grade tumors was 4000 cGy (range 3000-5100). A lens-sparing approach was used in 19 patients (37%). Late complications for the lens and cornea were scored according to the subjective, objective, management, and analytic (SOMA) scale of the Late Effects of Normal Tissue (LENT) scoring system. The median follow-up was 55 months (range 6-232). Results: The local control rate was 100% in the 52 orbits treated. The 5-year overall survival and relapse-free survival rate was 73.6% and 65.5%, respectively. Tumor grade and location did not predict for overall survival or relapse-free survival

    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.

The mechanisms responsible for this effectiveness might not be related to IgE production. Additionally, the effectiveness for nasal tissue was dissociated from that seen for the ocular tissue.

  15. Perceiving nasal patency through mucosal cooling rather than air temperature or nasal resistance.

    Directory of Open Access Journals (Sweden)

    Kai Zhao

    Full Text Available Adequate perception of nasal airflow (i.e., nasal patency is an important consideration for patients with nasal sinus diseases. The perception of a lack of nasal patency becomes the primary symptom that drives these patients to seek medical treatment. However, clinical assessment of nasal patency remains a challenge because we lack objective measurements that correlate well with what patients perceive. The current study examined factors that may influence perceived patency, including air temperature, humidity, mucosal cooling, nasal resistance, and trigeminal sensitivity. Forty-four healthy subjects rated nasal patency while sampling air from three facial exposure boxes that were ventilated with untreated room air, cold air, and dry air, respectively. In all conditions, air temperature and relative humidity inside each box were recorded with sensors connected to a computer. Nasal resistance and minimum airway cross-sectional area (MCA were measured using rhinomanometry and acoustic rhinometry, respectively. General trigeminal sensitivity was assessed through lateralization thresholds to butanol. No significant correlation was found between perceived patency and nasal resistance or MCA. In contrast, air temperature, humidity, and butanol threshold combined significantly contributed to the ratings of patency, with mucosal cooling (heat loss being the most heavily weighted predictor. Air humidity significantly influences perceived patency, suggesting that mucosal cooling rather than air temperature alone provides the trigeminal sensation that results in perception of patency. The dynamic cooling between the airstream and the mucosal wall may be quantified experimentally or computationally and could potentially lead to a new clinical evaluation tool.

    The endoscope is a new and highly useful instrument for transphenoidal surgery (TSS), and is generally used because of its minimally invasiveness. In addition, endoscopic transsphenoidal surgey (eTSS) has a potential for more radical tumor removal at the pituitary and the parasellar regions by wider visualization and more powerful illumination. To operate these regions safely, we need to know nasal and skull base anatomy under the endoscope which looks different from images under a microscope. In this paper, we demonstrated nasal and skull base anatomy with multi-detector computed tomography, which was performed in 23 recent patients with pituitary and parasellar legions. In the nasal legion, deviation of nasal septum and deviation of sphenoid ostium are important for endonasal approach of eTSS, and often determine the difficulty of surgery in the nasal cavity. Our study showed that deviation of nasal septum was seen in 26% of patients. Deviation of sphenoid ostium was 5.5±1.5 mm from the midline. The anatomy of sphenoid sinus plays a key role in our determination of the safety of a bony opening of the sella. In addition to sellar, presellar, and concha types, carotid prominence and optic prominence are important to determine the midline orientation. Development of carotid prominence was significantly related to the extent of lateral pneumatization of sphenoid sinus (P=0.0016). Reconstructed 3D-image of sphenoid sinus was very useful in visual understanding skull base anatomy. (author)

    Full Text Available Objective: Most of the malignant cutaneous carcinomas are seen in the nasal region. Reconstruction of nasal defects is challenging because of the unique anatomic properties and complex structure of this region. In this study, we present our algorithm for the nasal skin defects that occurred after malignant skin tumor excisions. Material and Methods: Patients whose nasal skin was reconstructed after malignant skin tumor excision were included in the study. These patients were evaluated by their age, gender, comorbities, tumor location, tumor size, reconstruction type, histopathological diagnosis, and tumor recurrence. Results: A total of 130 patients (70 female, 60 male were evaluated. The average age of the patients was 67.8 years. Tumors were located mostly at the dorsum, alar region, and tip of the nose. When reconstruction methods were evaluated, primary closure was preferred in 14.6% patients, full thickness skin grafts were used in 25.3% patients, and reconstruction with flaps were the choice in 60% patients. Different flaps were used according to the subunits. Mostly, dorsal nasal flaps, bilobed flaps, nasolabial flaps, and forehead flaps were used. Conclusion: The defect-only reconstruction principle was accepted in this study. Previously described subunits, such as the dorsum, tip, alar region, lateral wall, columella, and soft triangles, of the nose were further divided into subregions by their anatomical relations. An algorithm was planned with these sub regions. In nasal skin reconstruction, this algorithm helps in selection the methods for the best results and minimize the complications.

    2016-04-01

    Full Text Available Background: Epistaxis is a common problem in childhood. It has been shown that children with recurrent epistaxis are more likely to have nasal colonization with Staphylococcus aureus. It has been suggested that low-grade inflammation, crusting and increased vascularity due to bacterial colonization contributes to the development of epistaxis in children. Aims: This study aimed to investigate the nasal colonization and treatment outcome in pediatric epistaxis patients. Study Design: Retrospective cross-sectional study. Methods: Charts of the pediatric patients referred to our university hospital otolaryngology outpatient clinics for the evaluation of epistaxis were reviewed. The patients whose nasal cultures had been taken at the first clinical visit comprised the study group. Results: Staphylococcus aureus was the most common bacteria grown. The presence of crusting and hypervascularity was not dependent on the type of bacterial growth and there was no relation between hypervascularity and crusting of the nasal mucosa. Thirty-six patients were evaluated for the outcome analysis. Resolution of bleeding was not dependent on nasal colonization; in patients with colonization, there was no difference between topical antibacterial and non-antibacterial treatments. Conclusion: Despite the high colonization rates, topical antibacterial treatment was not found superior to non-antibacterial treatment. Our study does not support the belief that bacterial colonization results in hypervascularity of the septal mucosa causing epistaxis since no relation was found between nasal colonization, hypervascularity and crusting. The role of bacterial colonization in pediatric epistaxis need to be further investigated and treatment protocols must be determined accordingly.

    2013-09-01

    Migraine attacks exclusively felt in the face are very rare, the pain involving the territories supplied by the second and third branches of the trigeminal nerve. Two patients suffering from heminasal pain attacks accompanied with typical migrainous features and responsive to oral or intranasal triptans - but not to intranasal lidocaine or oxymetazoline. In one patient, the attacks could be precipitated upon slight touching on the tip of the nose, in the other attacks were preceded by the nasal sensation typically heralding sneezing. Migraine pain mostly develops within the innervation territory of the first branch of the trigeminal nerve, which includes the nose. Therefore, episodes of unilateral nasal pain with migrainous features could be considered a migraine with unusual topography (nasal migraine). Painful nasal attacks occasionally preceded by stimulation of trigeminal afferents in the nose, could be conceived of as migraine-tic syndrome.

    Nasal chondromesenchymal hamartoma (NCMH) is a benign tumor that was described in 1998. The occurrence of this lesion in the nasal cavity of infants and children is especially rare, with only 21 cases reported in the international literature. We report a 12-month-old boy with respiratory distress due to nasal obstruction. Computed tomographic scan and magnetic resonance imaging examination demonstrated a soft-tissue mass obstructing the left nasal cavity. Digital subtraction angiography and preoperative superselective embolization with microparticles were also performed. The tumor was completely resected surgically. Histopathology and immunohistochemical analyses of the tumor disclosed a NCMH. The imaging characteristics of the tumor are described and the radiology literature is reviewed.

  4. [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.

    2015-01-01

    Full Text Available Background: Malignant lymphomas arising in extranodal sites are intriguing. The histological types of lymphomas vary from one site to another. This study is undertaken to diagnose and categorize extranodal lymphomas using histochemistry and immunohistochemistry (IHC. Materials and Methods: Formalin processed paraffin blocks and hematoxylin and eosin stained sections were used for routine histology. IHC was done in all cases. Results: We have encountered 31 cases of extra nodal lymphomas over a period of 3 years. The tumors occurred at different sites, including brain, nasopharynx, nose, gastrointestinal tract, thyroid, bone, testis, breast, lung, vagina, and skin. Majority of the cases were B-cell lymphomas, while four cases were T-cell lymphomas. Among the B-cell lymphomas diffuse large B-cell lymphoma was the most common variant. Conclusion: This study reiterates the key role of IHC particularly when the differential diagnosis includes an undifferentiated epithelial malignancy and a high-grade lymphoma in the extranodal sites as the treatment modalities and prognosis are different.

    Full Text Available Data supporting the role of radiotherapy in secondary trigeminal nerve lymphoma is scarce. Here, I report the case of 64-year-old Thai male diagnosed as gastric diffuse large B cell lymphoma with secondary trigeminal nerve lymphoma. He had previously received one cycle of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP, followed by five cycles of rituximab plus CHOP (R-CHOP with intrathecal methotrexate (MTX and cytarabine (Ara-C. One month after the last cycle of R-CHOP, he developed a headache and numbness on the left side of his face. MRI revealed thickening of the left trigeminal nerve. He received one intrathecal injection of MTX and Ara-C, followed by systemic chemotherapy. After receiving intrathecal chemotherapy, his symptoms disappeared. Clinical response and MRI studies suggested secondary trigeminal nerve lymphoma. Two months later, our patient’s secondary trigeminal nerve lymphoma had progressed. Salvage whole brain irradiation (36 Gy with boost dose (50 Gy along the left trigeminal nerve was given. Unfortunately, our patient developed heart failure and expired during the radiotherapy session. In conclusion and specific to secondary central nervous system lymphoma (SCNSL, radiotherapy may benefit patients who fail to respond to systemic chemotherapy and palliative treatment. The results this report fail to support the role of radiotherapy in secondary trigeminal nerve lymphoma.

    2017-04-01

    Full Text Available BACKGROUND The orbit is an area of considerable interest to the otolaryngologist because of its close anatomical relationship to the Paranasal Sinuses (PNS. PNS may be involved in various types of pathology arising in the nose and paranasal sinuses. Surgical procedures of the nose and PNS may sometimes involve the orbit or its contents. Infections of the paranasal sinuses may spread to the orbit through suture lines, congenital or acquired bony dehiscence and retrograde thrombophlebitis and by bone necrosis or bony erosion. Neoplasms of the PNS also can involve the orbit. Hence, knowledge of the anatomy of the orbit is very important. The several of diseases of PNS in a tertiary hospital were included in the study and the data analysed. The aim of the study is to determine the type of orbital complications of nasal and paranasal sinus diseases and to evaluate the management protocol in orbital complications of nasal and paranasal sinus diseases.

    The pattern of tumor recurrence was assessed in 24 dogs receiving cobalt radiation therapy for nasal carcinoma. Dogs were evaluated using nasal cavity computed tomography prior to treatment, and at 1, 3, 6 and 12 months after treatment, and at 6-month intervals thereafter if still alive. Dogs were treated with various combinations of total dose, and fraction size. Total doses were normalized to equivalent doses given in 3.0 Gy fractions. The extent of tumor regression or duration of tumor control were not dependent on absolute total dose, normalized total dose, or tumor type. The median duration of local control in all dogs was 312 days. Marked tumor regression was observed in 11 of the 24 dogs. Median duration of local control was significantly longer in dogs with marked tumor regression in comparison to dogs without tumor regression; 389 vs. 161 days respectively. When tumor recurrence was documented in dogs having tumor regression, the location of the recurrence was in the nasal cavity. No tumor recurred in a sinus or periorbital region, and only one geographic miss was detected. Tumor recurrence in the irradiated volume, including dogs with and without marked regression, was documented in 13 of the 24 dogs. The high local failure rate, coupled with the recurrence pattern in these dogs, suggests there may be an opportunity for improvement in local control through use of shrinking field techniques

    Full Text Available Background. Eosinophilic angiocentric fibrosis (EAF is a rare benign condition of unknown aetiology that causes stenosis of the upper respiratory tract. It is most commonly found at the nasal septum and sinus mucosa causing mucosal thickening and nasal obstructive symptoms. The diagnosis is mainly based on characteristic histologic findings. Case Report. A 27-year-old young woman presented with a slow growing mass at her anterior nasal septum for over eight years. She complained of persistent nasal obstruction, epistaxis, sometimes diffused facial pain, and chronic headache. 3 years ago, the tumor was partially resected for ventilation and a nasal septum perforation was left. Imaging findings indicated soft-tissue thickening of the anterior part of septum and adjacent lateral nasal walls. Pathological examination showed numerous inflammatory cells infiltrates containing eosinophils, fibroinflammatory lesion with a whorled appearance fibrosis which typically surrounded vessels. A diagnosis of eosinophilic angiocentric fibrosis was made. All laboratory tests were unremarkable. Skin prick test was positive. The tumor-like lesion was totally resected. Conclusions. EAF is a rare benign and progressive disorder causing destruction. Combined with radiological imaging of EAF historical findings contribute to the diagnosis. It is important to prevent tumor from recurrence by total resection of the lesion.

    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

    Nasal packing is an option for bleeding control after endoscopic sinus surgery and septoplasty. Although new packing materials have been developed, patients still suffer from pain and require additional analgesics treatments. In this study, a prospective, randomized, and double-blind controlled trial was designed to evaluate the effect of fentanyl-soaked packing on pain after endoscopic sinus surgery and septoplasty. One hundred fifty-two patients who underwent nasal surgeries due to chronic rhinosinusitis or nasal septal deviation were enrolled in this study. At the end of operation, 50 mcg fentanyl-soaked biodegradable synthetic polyurethane foams packing Nasopore or Merocel were applied to a group of 79 patients, and saline-soaked ones were applied to another group of 73 patients. To evaluate the influence of fentanyl on postoperative nasal pain, patients' conditions were assessed via means of Numeric Rating Scale, patient satisfaction, and Ramsay Sedation Scale. In addition, symptoms of headache or sore throat and any signs of cardiopulmonary-relevant indicators were monitored. The fentanyl group had significantly decreased Numeric Rating Scale and increased patient satisfaction in every operation type for the majority of postoperative time periods ( P fentanyl group showed a higher score on Ramsay Sedation Scale than the control group ( P .05). Fentanyl group showed significantly reduced postoperative pain without serious adverse effects. We suggest that topical fentanyl application to nasal packs can be a useful method to reduce pain during the early postoperative period after endoscopic sinus surgery and septoplasty.

  20. Splenic marginal zone lymphoma.

    Piris, Miguel A; Onaindía, Arantza; Mollejo, Manuela

    Splenic marginal zone lymphoma (SMZL) is an indolent small B-cell lymphoma involving the spleen and bone marrow characterized by a micronodular tumoral infiltration that replaces the preexisting lymphoid follicles and shows marginal zone differentiation as a distinctive finding. SMZL cases are characterized by prominent splenomegaly and bone marrow and peripheral blood infiltration. Cells in peripheral blood show a villous cytology. Bone marrow and peripheral blood characteristic features usually allow a diagnosis of SMZL to be performed. Mutational spectrum of SMZL identifies specific findings, such as 7q loss and NOTCH2 and KLF2 mutations, both genes related with marginal zone differentiation. There is a striking clinical variability in SMZL cases, dependent of the tumoral load and performance status. Specific molecular markers such as 7q loss, p53 loss/mutation, NOTCH2 and KLF2 mutations have been found to be associated with the clinical variability. Distinction from Monoclonal B-cell lymphocytosis with marginal zone phenotype is still an open issue that requires identification of precise and specific thresholds with clinical meaning.

    Full Text Available Background: The prevalence of coeliac disease is around 1% in general population but this is often unrecognised. The classical presentation of adult coeliac disease is characterized by diarrhoea and malabsorption syndrome, but atypical presentations are probably more common and are characterized by iron deficiency anaemia, weight loss, fatigue, infertility, arthralgia, peripheral neuropathy and osteoporosis. Unusual are the coagulation disorders (prevalence 20% and these are due to vitamin K malabsorption (prolonged prothrombin time. Clinical case: A 64-year-old man was admitted to our Department for an extensive spontaneous haematoma of the right leg. He had a history of a small bowel resection for T-cell lymphoma, with a negative follow-up and he didn’t report any personal or familiar history of bleeding. Laboratory tests showed markedly prolonged prothrombin (PT and partial-thromboplastin time (PTT, corrected by mixing studies, and whereas platelet count and liver tests was normal. A single dose (10 mg of intravenous vitamin K normalized the PT. Several days before the patient had been exposed to a superwarfarin pesticide, but diagnostic tests for brodifacoum, bromadiolone or difenacoum were negative. Diagnosis of multiple vitamin K-dependent coagulationfactor deficiencies (II, VII, IX, X due to intestinal malabsorption was made and coeliac disease was detected. Therefore the previous lymphoma diagnosis might be closely related to coeliac disease. Conclusions: A gluten free diet improves quality of life and restores normal nutritional and biochemical status and protects against these complications.

  2. Lymphoma Caused by Intestinal Microbiota

    Full Text Available The intestinal microbiota and gut immune system must constantly communicate to maintain a balance between tolerance and activation: on the one hand, our immune system should protect us from pathogenic microbes and on the other hand, most of the millions of microbes in and on our body are innocuous symbionts and some can even be beneficial. Since there is such a close interaction between the immune system and the intestinal microbiota, it is not surprising that some lymphomas such as mucosal-associated lymphoid tissue (MALT lymphoma have been shown to be caused by the presence of certain bacteria. Animal models played an important role in establishing causation and mechanism of bacteria-induced MALT lymphoma. In this review we discuss different ways that animal models have been applied to establish a link between the gut microbiota and lymphoma and how animal models have helped to elucidate mechanisms of microbiota-induced lymphoma. While there are not a plethora of studies demonstrating a connection between microbiota and lymphoma development, we believe that animal models are a system which can be exploited in the future to enhance our understanding of causation and improve prognosis and treatment of lymphoma.

    Nasal deposition studies can demonstrate whether nasal sprays treating allergic rhinitis and polyposis reach the ciliated posterior nasal cavity, where turbinate inflammation and other pathology occurs. However, quantifying nasal deposition is challenging, because in vitro tests do not correlate to human nasal deposition; gamma scintigraphy studies are thus used. For valid data, the radiolabel must distribute, as the drug, into different-sized droplets, remain associated with the drug in the formulation after administration, and not alter its deposition. Some nasal deposition studies have demonstrated this using homogenous solutions. However, most commercial nasal sprays are heterogeneous suspensions. Using mometasone furoate nasal suspension (MFS), we developed a technique to validate radiolabel deposition as a surrogate for nasal cavity drug deposition and characterized regional deposition and nasal clearance in humans. Mometasone furoate (MF) formulation was spiked with diethylene triamine pentacaetic acid. Both unlabeled and radiolabeled formulations (n = 3) were sprayed into a regionally divided nasal cast. Drug deposition was quantified by high pressure liquid chromatography within each region; radiolabel deposition was determined by gamma camera. Healthy subjects (n = 12) were dosed and imaged for six hours. Scintigraphic images were coregistered with magnetic resonance imaging scans to quantify anterior and posterior nasal cavity deposition and mucociliary clearance. The ratio of radiolabel to unlabeled drug was 1.05 in the nasal cast and regionally appeared to match, indicating that in vivo radiolabel deposition could represent drug deposition. In humans, MFS delivered 86% (9.2) of metered dose to the nasal cavity, approximately 60% (9.1) of metered dose to the posterior nasal cavity. After 15 minutes, mucociliary clearance removed 59% of the initial radiolabel in the nasal cavity, consistent with clearance rates from the ciliated posterior surface. MFS

    Bcl11b is a haploinsufficient tumor suppressor gene and expressed in many tissues such as thymus, brain and skin. Irradiated Bcl11b +/- heterozygous mice mostly develop thymic lymphomas, but the preference of Bcl11b inactivation for thymic lymphomas remains to be addressed. We produced Bcl11b +/- heterozygous and Bcl11b wild-type mice of p53 +/- background and compared their incidence of γ-ray induced thymic lymphomas. Majority of the tumors in p53 +/- mice were skin tumors, and only 5 (36%) of the 14 tumors were thymic lymphomas. In contrast, Bcl11b +/- p53 +/- doubly heterozygous mice developed thymic lymphomas at the frequency of 27 (79%) of the 34 tumors developed (P = 0.008). This indicates the preference of Bcl11b impairment for thymic lymphoma development. We also analyzed loss of the wild-type alleles in the 27 lymphomas, a predicted consequence given by γ-irradiation. However, the loss frequency was low, only six (22%) for Bcl11b and five (19%) for p53. The frequencies did not differ from those of spontaneously developed thymic lymphomas in the doubly heterozygous mice, though the latency of lymphoma development markedly differed between them. This suggests that the main contribution of irradiation at least in those mice is not for the tumor initiation by inducing allelic losses but probably for the promotion of thymic lymphoma development

    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.

    2007-08-01

    Full Text Available Abstract Background The nasal cavity of all vertebrates houses multiple chemosensors, either innervated by the Ist (olfactory or the Vth (trigeminal cranial nerve. Various types of receptor cells are present, either segregated in different compartments (e.g. in rodents or mingled in one epithelium (e.g. fish. In addition, solitary chemosensory cells have been reported for several species. Alligators which seek their prey both above and under water have only one nasal compartment. Information about their olfactory epithelium is limited. Since alligators seem to detect both volatile and water-soluble odour cues, I tested whether different sensory cell types are present in the olfactory epithelium. Results Electron microscopy and immunocytochemistry were used to examine the sensory epithelium of the nasal cavity of the American alligator. Almost the entire nasal cavity is lined with olfactory (sensory epithelium. Two types of olfactory sensory neurons are present. Both types bear cilia as well as microvilli at their apical endings and express the typical markers for olfactory neurons. The density of these olfactory neurons varies along the nasal cavity. In addition, solitary chemosensory cells innervated by trigeminal nerve fibres, are intermingled with olfactory sensory neurons. Solitary chemosensory cells express components of the PLC-transduction cascade found in solitary chemosensory cells in rodents. Conclusion The nasal cavity of the American alligator contains two different chemosensory systems incorporated in the same sensory epithelium: the olfactory system proper and solitary chemosensory cells. The olfactory system contains two morphological distinct types of ciliated olfactory receptor neurons.

    Transition of cells from quiescence to proliferation requires an increase in the rate of protein synthesis, which is regulated in part by two key translation initiation factors, 4E and 2α. The expression and activity of both factors are increased transiently when normal resting cells are stimulated to proliferate. They are constitutively elevated in oncogene transformed cultured cells, and overexpression of either initiation factor in rodent cells makes them tumorigenic. In this study we investigate an association between the expression of translation initiation factors and lymphomagenesis. We have analyzed the expression of the protein synthesis initiation factors 4E and 2α by immunohistochemistry in reactive lymph nodes and several types of non-Hodgkin’s lymphoma representing a wide range of clinical behaviors based on the Revised European-American Lymphoma behavioral classification. The study included 7 benign lymph nodes with follicular hyperplasia, 26 indolent lymphomas (6 marginal zone lymphomas, 7 small lymphocytic lymphomas, and 13 follicular lymphomas, grades 1 and 2), 16 moderately aggressive lymphomas (8 mantle cell lymphomas and 8 follicular lymphomas, grade 3), 24 aggressive lymphomas (14 large-B-cell lymphomas and 10 anaplastic large-cell lymphomas), and 15 highly aggressive lymphomas (7 lymphoblastic lymphomas and 8 Burkitt’s lymphomas). Strong expression of initiation factors 4E and 2α was demonstrated in the germinal centers of reactive follicles. Minimal or no expression was seen in the mantle zones and surrounding paracortices, indicating that high expression of initiation factors 4E and 2α is associated with the active proliferation of lymphocytes. Most cases of aggressive and highly aggressive lymphomas showed strong expression of initiation factors 4E and 2α, in contrast to the cases of indolent and moderately aggressive lymphoma, in which their expression was intermediate between the germinal centers and the mantles of reactive

    Full Text Available Introduction: The nasal Polyposis is a non-neoplastic chronic inflammatory process of the nasal mucosa. It causes a large impact to the patients' life quality. Objective: To analyze the characteristics of patients with polyposis in the Brazilian population. Method: 50 records of patients followed up in a tertiary hospital and submitted to surgical treatment of nasal polyposis were reviewed. The following variables were analyzed: age, sex, smoking, presence of asthma, presence of AAS intolerance and also the clinical manifestations: anterior and posterior rhinorrhea, nasal obstruction, hyposmia, sneezing and pruritus. The tomographic evaluation system applied was that of Lund-McKay. For statistical analysis we applied the chi-square test with p<0.05. Results: Out of 50 patients evaluated, 28 were male and 22 were female. The mean age range was of 40.8 years. The main clinical manifestation was nasal obstruction in 100% of the patients. In the tomographic evaluation, according to the Lund-McKay system, the average scoring was of 10.9. Discussion: No statistically significant difference was obtained in the patients' general symptoms compared to the patients with asthma or AAS intolerance. The difference in the Lund-McKay score was statistically significant in the populations studied. The symptoms were similar to the frequency of symptoms of other works. Conclusion: We concluded that the main complaint of the patients with nasal polyposis is nasal obstruction, the most affected age is of about 40 years old, without preference of sex. The severity of tomographic findings is higher in patients with asthma and AAS intolerance.

    Somatostatin receptor (SSTR) scintigraphy and gallium-67 citrate ({sup 67}Ga) scintigraphy have been used for visualisation of Hodgkin's lymphoma and non-Hodgkin's lymphoma. However, experience with B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) type is very limited. The aim of this study was to prospectively compare the {sup 67}Ga scintigraphy results with those obtained by {sup 111}In-DOTA-dPhe{sup 1}-Tyr{sup 3}-octreotide ({sup 111}In-DOTA-TOCT) and {sup 111}In-DOTA-lanreotide ({sup 111}In-DOTA-LAN) scintigraphy in patients with proven MALT-type lymphoma. Comparative scintigraphic examinations using {sup 67}Ga, {sup 111}In-DOTA-TOCT and {sup 111}In-DOTA-LAN were performed in 18 patients (11 female and 7 male, median age 64{+-}15 years) with histologically verified MALT-type lymphomas of various origin.

    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.

    Follicular non-Hodgkin's lymphoma (NHL) is a unique subtype of NHL, which is indolent, incurable with a high prevalence of residual mass after treatment, and may transform to more aggressive NHL. The aim of this review is to (1) describe the histological and flow cytometry characteristics of follicular NHL; (2) introduce the Follicular Lymphoma International Prognostic Index 2 (FLIPI-2), which allows better treatment selection and patient stratification for clinical trials; (3) illustrate the classic and atypical ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and positron-emission tomography (PET)/CT appearance of follicular NHL; and (4) characterize the appearance of nodal and extranodal follicular NHL with pathological correlation. Imaging is essential in every step of the management of patients with follicular lymphoma. Overall survival is improved with better predictive tools and new targeted biological therapies. Radiologists should be aware of possible active residual mass, indolent recurrence, transformation, and association with other primary cancers in patients treated for follicular lymphoma.

    Nasal obstruction is considered to be a potential etiological factor in sleep-disordered breathing. However, a significant correlation between nasal measurements and obstructive sleep apnea has not been demonstrated so far. The aim of this study was to investigate the relationships between nasal resistance, nasal volumes and selected sleep parameters using nasal measurements performed in both seated and supine positions. We also investigated whether snoring patients in our clinical sample showed increased positional or decongestive nasal mucosal changes. Forty-one snoring men on a waiting list for correction of nasal obstruction underwent polysomnography, anterior rhinomanometry and acoustic rhinometry. Nineteen non-snoring control subjects were also recruited. Nasal measurements were performed in a seated position, after lying down in a supine position and, after decongestion of nasal mucosa, in a seated position again. In the overall patient group, nasal volume at a distance 2-4 cm from the nares in the supine position correlated inversely with apnea-hypopnea index (AHI) (r = -0.32, p patients, total nasal resistance measured in a supine position correlated with AHI (r = 0.50, p position and sleep parameters. Postural or decongestive changes in nasal measurements were not increased in snoring patients compared with control subjects. The relationship found between nasal measurements and sleep parameters suggests that nasal obstruction does augment airway collapse.

    Full Text Available We evaluated the expression of 10 adhesion molecules on peripheral blood tumor cells of 17 patients with chronic lymphocytic leukemia, 17 with mantle-cell lymphoma, and 13 with nodal or splenic marginal B-cell lymphoma, all in the leukemic phase and before the beginning of any therapy. The diagnosis of B-cell non-Hodgkin's lymphomas was based on cytological, histological, immunophenotypic, and molecular biology methods. The mean fluorescence intensity of the adhesion molecules in tumor cells was measured by flow cytometry of CD19-positive cells and differed amongst the types of lymphomas. Comparison of chronic lymphocytic leukemia and mantle-cell lymphoma showed that the former presented a higher expression of CD11c and CD49c, and a lower expression of CD11b and CD49d adhesion molecules. Comparison of chronic lymphocytic leukemia and marginal B-cell lymphoma showed that the former presented a higher expression of CD49c and a lower expression of CD11a, CD11b, CD18, CD49d, CD29, and CD54. Finally, comparison of mantle-cell lymphoma and marginal B-cell lymphoma showed that marginal B-cell lymphoma had a higher expression of CD11a, CD11c, CD18, CD29, and CD54. Thus, the CD49c/CD49d pair consistently demonstrated a distinct pattern of expression in chronic lymphocytic leukemia compared with mantle-cell lymphoma and marginal B-cell lymphoma, which could be helpful for the differential diagnosis. Moreover, the distinct profiles of adhesion molecules in these diseases may be responsible for their different capacities to invade the blood stream.

    The diagnosis of malignant lymphoma during pregnancy is always a challenging situation, as for the patient a her family as well as for the whole medical team. Medical and communication skills are crucial in this situation. Interdisciplinary approach and a close cooperation between oncologist, obstetrician and neonatologist are equally important. The diagnosis of malignant potentially lethal disease and the need of treatment during pregnancy raise concerns about the life of mother if treatment was delayed and at the same time concerns about adverse fetal outcomes. This gives raise dilemmas at the therapeutical, ethical, moral and social levels. The patient must be included in the decisional process and the cultural as well as the religious aspects must be taken into account. (author)

    From 1966 to 1985, 103 patients with a localized follicular lymphoma were treated at the Fondation Bergonie. Clinical staging was performed using, after physical examination, chest X-rays, bipedal lymphangiography and unilateral bone marrow biopsy (BMB). The patients were then treated by radiotherapy with or without chemotherapy. Overall survival (OS) at 5 and 10 years is 69 and 56.3%, respectively. Relapse-free survival (RFS) is 53.7 and 49%. Unifactorial analysis shows three prognostic parameters to be independently significant in terms of OS: age, stage and B symptons. In terms of RFS, only 2 factors are significant: age and B symptons. Multivariate analysis (Cox model) shows that age is a more important prognostic factor than stage. 40 refs.; 3 figs.; 3 tabs

    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.

    Full Text Available Objective: A variety of nasal skin reconstruction methods are available to meet the esthetic patient's needs. In this article, we review some of modifications of these procedures and share our experience in reconstruction of different parts of the nasal skin following skin tumor ablation. Patients and Methods : From January 2010 to January 2014, 171 patients underwent nasal skin reconstruction after excising cancerous lesions of the involved nasal skin. The patient's history, pre- and post-operation photographs, and the surgery data were collected and assessed. Demographic data related to the type of cancer, defect size and location, type of reconstruction were collected. Results: A variety of local flaps were used based on location and defect features. Nearly all flaps healed primarily without postsurgical significant complications. Conclusion: According to the results and the outcomes of the operations, we concluded that a certain flaps are more effective than others in nasal skin reconstruction. Local flap reconstruction of the nose has good esthetic result with low complication rate.

  5. Molecular Pathogenesis of MALT Lymphoma

    Directory of Open Access Journals (Sweden)

    Katharina Troppan

    2015-01-01

    Full Text Available Approximately 8% of all non-Hodgkin lymphomas are extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT, also known as MALT lymphoma, which was first described in 1983 by Isaacson and Wright. MALT lymphomas arise at a wide range of different extranodal sites, with the highest frequency in the stomach, followed by lung, ocular adnexa, and thyroid, and with a low percentage in the small intestine. Interestingly, at least 3 different, apparently site-specific, chromosomal translocations and missense and frameshift mutations, all pathway-related genes affecting the NF-κB signal, have been implicated in the development and progression of MALT lymphoma. However, these genetic abnormalities alone are not sufficient for malignant transformation. There is now increasing evidence suggesting that the oncogenic product of translocation cooperates with immunological stimulation in oncogenesis, that is, the association with chronic bacterial infection or autoaggressive process. This review mainly discusses MALT lymphomas in terms of their genetic aberration and association with chronic infections and summarizes recent advances in their molecular pathogenesis.

    Between 2000 and 2007, 17 patients with localized gastric lymphoma (10 mucosa-associated lymphoid tissue lymphomas and 7 diffuse large B-cell lymphomas) were treated with radiotherapy alone or doxorubicin-based chemotherapy followed by radiotherapy. Radiation dose of mucosa-associated lymphoid tissue (MALT) lymphoma was 30 Gy with a daily fraction size of 1.5 Gy. Sixteen patients achieved complete remission and the 5-year overall survival of MALT lymphoma and diffuse large B-cell lymphoma (DLBCL) were 100% and 87%, respectively. No gastric perforation and hemorrhage were noticed. Using AP/LR 2-port radiotherapy markedly decreased the liver dose. (author)

    We systematically studied the expression of more than fifty histone and DNA (de)methylating enzymes in lymphoma and healthy controls. As a main result, we found that the expression levels of nearly all enzymes become markedly disturbed in lymphoma, suggesting deregulation of large parts of the epigenetic machinery. We discuss the effect of DNA promoter methylation and of transcriptional activity in the context of mutated epigenetic modifiers such as EZH2 and MLL2. As another mechanism, we studied the coupling between the energy metabolism and epigenetics via metabolites that act as cofactors of JmjC-type demethylases. Our study results suggest that Burkitt’s lymphoma and diffuse large B-cell Lymphoma differ by an imbalance of repressive and poised promoters, which is governed predominantly by the activity of methyltransferases and the underrepresentation of demethylases in this regulation. The data further suggest that coupling of epigenetics with the energy metabolism can also be an important factor in lymphomagenesis in the absence of direct mutations of genes in metabolic pathways. Understanding of epigenetic deregulation in lymphoma and possibly in cancers in general must go beyond simple schemes using only a few modes of regulation. PMID:26506391

    Technetium-99m methoxy-isobutyl-isonitrile (sestamibi) imaging of malignant canine lymphoma was performed in thirteen dogs 1 hour after intravenous injection of 99mTc-sestamibi at 13 MBq (0.35 mCi) per kilogram body weight. Abnormal tracer uptake was visualized in the liver, spleen, bone marrow, and mesenteric, inguinal, popliteal, sternal, cranial cervical and mandibular lymph nodes. Radiopharmaceutical uptake was also noted in a nasal mass. One large neoplastic renal mass did not have demonstrable sestamibi uptake. Other regions had no significant difference in the target:background ratios when compared with values from normal dogs (P > 0.05). 99mTc-sestamibi can be used to image malignant lymphoma, and has potential applications in the management of patients to document response to treatment and to stage of extent of disease

Case Presentation We report an unusual case of sporadic Burkitt’s lymphoma (BL presenting with massive bilateral ovarian infiltration, peritoneal carcinomatosis and diffuse nodular lesions of the stomach and the intestine mimicking Krukenberg tumor. Diagnostic biopsies were obtained by endoscopy of the upper gastrointestinal tract. With intensive chemotherapy, complete remission was rapidly achieved, without life-threatening tumor lysis syndrome. Conclusion Besides metastatic gastric adenocarcinoma, BL is an important differential diagnosis in adolescents presenting with Krukenberg tumor.

    Full Text Available A 93-year-old female was transferred to the emergency ward of our hospital due to disturbance of consciousness and hypotension. Computed tomography showed bilateral pleural and pericardial effusion without evidence of tumor masses or lymphadenopathy. Cytodiagnosis of pleural effusion revealed proliferation of atypical lymphoid-like cells with pan-B surface markers. We suspected primary effusion lymphoma-like lymphoma; however, the monoclonality of these cells was not confirmed. Cytodiagnosis of bone marrow revealed lymphoma cells with monoclonal B-cell markers. These findings prompted a diagnosis of diffuse large B-cell lymphoma with bone marrow invasion. In the case of pericardial or pleural effusion, clinicians should consider carefully both hematological malignancy and its classification.

    Full Text Available Primary non-Hodgkin’s lymphomas (NHL of the sinonasal tract are rather uncommon entities. Morphologically and radiographically, sinonasal lymphomas are difficult to distinguish from other malignant neoplasms or non- neoplastic processes. They have a variable presentation from fulminant destructive manifestations to chronic indolent type of disease and may mimic as carcinomas and invasive fungal infection respectively. We report a case of primary NHL involving sinonasal tract in elderly female, which was clinically and radiologically mimicking as sinonasal malignany and was proven as NHL on histological examination and confirmed by immunohistochemistry. A high index of suspicion, appropriate histopathological examination and immunohistochemistry is necessary to differentiate sinonasal lymphomas from other possibilities. Failure to do so may miss the diagnosis and delay appropriate treatment

    We report four cases of lingual tonsillar MALT (mucosal associated lymphoid tissue) lymphoma. The cases consisted of a 68-year-old woman, a 60-year-old woman, a 55-year-old woman, and a 75-year-old man. The clinical stages of these cases were IIA, IA, IV (invasion to bone marrow) and IA, respectively. As some types of lingual tonsillar MALT lymphomas show hypertrophy of the lymphoid tissue but not a mass, it is not easy to make a diagnosis of MALT lymphoma only by fiberscopic findings. Furthermore, the small size of biopsy specimens or tissue damaged by forceps can show a false negative consult. Repeat biopsies are sometimes required for a definitive diagnosis. It is important to take large biopsy specimens with little damage, and to discuss well with pathologists. (author)

    To evaluate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage in patients with diabetic foot ulcer (DFU) in Taiwan, and to assess the concordance between colonizing and clinical MRSA isolates from the patients. A total of 354 nasal specimens were collected from 112 to 242 diabetic patients with and without foot ulcer, respectively. MRSA clinical isolates from DFU wound cultures were collected for comparison. Nasal carriage rate of S. aureus and MRSA was similar between diabetic patients with and without foot ulcer (15.2% vs. 16.9% for S. aureus and 5.4% vs. 1.7% for MRSA). Nasal S. aureus colonization was an independent predictor for wound S. aureus infection (Odds ratio [OR]: 5.33, 95% confidence interval [CI]: 1.61-17.59), so did nasal MRSA colonization (OR: 19.09, 95% CI: 2.12-171.91). The levels of glycated hemoglobin, and the usage with immunosuppressant agent were associated with S. aureus nasal colonization while oral hypoglycemic agent usage a protective factor. Sequence type 59/staphylococcal chromosome cassette mec IV or V, the local endemic community-associated clone, accounted for 42% and 70% of the clinical and colonizing isolates, respectively. Six of 10 patients with paired colonizing and clinical isolates, either MRSA or methicillin-sensitive S. aureus, had a genetically identical strain from a single patient. Less than one-fifth of patients with DFU have nasal S. aureus, including MRSA, colonization; however, the colonization is significantly associated with S. aureus diabetic foot infection. Screening for S. aureus colonizing status in DFU patients might have a potential clinical implication. Copyright © 2018. Published by Elsevier B.V.

    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.

We report here a case of primary cutaneous marginal zone B-cell lymphoma in a 51 year-old man in which the diagnosis was made using both histology and immunopathology. The patient had no remarkable medical history, no history of either acute inflammation or insect bite, and presented with a 5 cm solitary asymptomatic erythematous firm, multinodular and infiltrated plaque on the back for 12 months. Histological examination and immunohistochemical study of a cutaneous biopsy provided a differential diagnosis between B cell lymphoma and lymphocytoma cutis. Full body work up revealed no signs of extracutaneous dissemination. The patient underwent surgical excision of the nodule. Histological examination showed a histological and immunophenotyping profile typical of primary cutaneous marginal zone B-cell lymphoma. The lesion was completely excised with clear margins and no recurrence occurred after a 12 month-follow-up period. Primary cutaneous marginal zone B-cell lymphoma are low-grade lymphomas that have an indolent course and a high tendency to recur. They should be differentiated from lymphocytoma cutis and from the other types of cutaneous B cell lymphomas that have a different course and prognosis.

    A 5-year-old, intact male, stray dog was presented in poor body condition, with pallor, muzzle deformity, multiple oozing fistulas with grass awns, bilateral sanguinopurulent nasal discharge and a fleshy friable mass occupying part of the hard palate. A friable mass occupying both nasal cavities was found on rhinoscopy. The dog had moderate nonregenerative normochromic-microcytic anemia, thrombocytopenia, hyperglobulinemia, and hypoalbuminemia. Cytologic preparations of the nasal and oral masses contained a neoplastic population of round cells with intracytoplasmic and extracellular vacuoles. Leishmania amastigotes also were observed, in the cytoplasm of macrophages and, occasionally, within neoplastic cells. A diagnosis of transmissible venereal tumor and concurrent leishmaniosis was made. Treatment with vincristine and allopurinol resulted in complete resolution of clinical signs and disappearance of the masses. The presence of amastigotes in neoplastic TVT cells may suggest an alternative mode of transmission of canine leishmaniosis where these diseases co-exist.

    Long-term use of silver-containing products is associated with a permanent bluish-gray discoloration of the skin known as argyria, but they remain widely available despite several measures by the FDA to regulate them. Several recent case reports have described the occurrence of argyria as a result of using these "natural" products. We used the five most common Internet search engines to find Web sites providing information on silver-containing nasal sprays. Of 49 Web sites analyzed, only 2 (4%) mentioned argyria as a possible complication, although 30 (61%) did caution against long-term use. Eight sites (16%) made specific claims about the health benefits of the product. All 49 sites (100%) provided direct or indirect links to buy silver-containing nasal sprays. We conclude that information about silver-containing nasal sprays on the Internet is misleading and inaccurate. Therefore, otolaryngologists should be aware of the misinformation their patients may be receiving about these products.

    The results of treatment in 175 consecutive patients with non-Hodgkin lymphoma (NHL) clinical stage I treated between 1969 and 1984 were analysed according to different pretreatment prognostic variables. Treatment consisted of radiotherapy in 166 of the 175 patients. The estimated 5 and 10-year disease-free survival rates (DFS) were 63% and 60% and the survival rates at 5 and 10 years 82% and 76% respectively. Lymphomas arising from gut-associated lymphoid tissue, i.e. Waldeyer's ring, the thyroid and the gastrointestinal tract had a more favourable clinical course (10-year projected DFS 83%) than nodal (50%) and other extranodal lymphomas. Although the number of patients with other extranodal sites was small, sites such as testis, nasal cavity, paranasal sinus and extradural space seemed to have a high relapse rate. Unfavourable clinical courses were also observed among nodal high-grade NHL if the lymph nodes were larger than 5 cm in diameter. Chemotherapy before radiotherapy may be recommended in NHL subgroups with a high relapse rate and which today are potentially curable with chemotherapy, i.e. high-grade NHL. This study indicates that large nodal lymphomas and some extranodal sites belong to this group. (orig.)

    Allergic rhinitis is usually treated with oral antihistamines or nasal steroids. Topically active nasal antihistamine is a new treatment modality for allergic rhinitis. The efficacy in comparison to well established topical treatment alternatives is not fully known. To compare the efficacy of intranasally administered azelastine to budesonide, at their respectively recommended dosage, on the symptoms of perennial rhinitis patients. A placebo-controlled, randomized, parallel group study was conducted to compare the efficacy and tolerability of intranasal budesonide aqueous suspension (256 microg once daily) with azelastine hydrochloride nasal spray (280 microg twice daily (560 microg/day)) and with placebo in the treatment of perennial allergic rhinitis. The 195 patients (with at least a 2-year history of perennial allergic rhinitis) recorded individual nasal symptom scores, the degree of symptom control achieved and any adverse events experienced over a 2-week baseline period and a 6-week treatment period. Following treatment, the reductions in mean combined and individual nasal symptom scores from baseline values were significantly greater in the budesonide group compared with the placebo group (P < .0001 for all variables except runny nose P = .01). In patients treated with budesonide, there were also significantly larger reductions from baseline values in combined nasal symptom scores (P < .01) and in scores for all individual nasal symptoms (P < or = .05) compared with those treated with azelastine. The reductions from baseline in both combined and individual nasal symptom scores did not differ between azelastine and placebo. The study medications were well tolerated, producing no unexpected or serious treatment-related adverse events. A once-daily dose of 256 microg of intranasal budesonide aqueous suspension is significantly more effective at relieving the symptoms of perennial allergic rhinitis compared with a twice daily dose of 280 microg of azelastine

    Full Text Available BackgroundPathogens in the nasal cavity during nasal surgery could lead to a systemic infectious condition, such as bacteremia, nosocomial infection, or toxic shock syndrome. However, there is no research about the prevalence of nasal carriage in patients with nasal bone fracture.MethodsThis was a prospective, double-blind, randomized study about the rate of nasal carriage in 200 patients with nasal bone fracture in Korea. Nasal secretions were taken from both the middle nasal meatus and colonized. All analyses were carried out using SPSS software.ResultsPathogens were identified in 178 of the 200 cases. Coagulase-negative staphylococci (CNS were the most cultured bacteria in 127 (66.84% of the 190 total patients after excluding 10 cases of contaminated samples, and methicillin-resistant coagulase-negative staphylococci (MRCNS were found in 48 (25.26%. Staphylococcus aureus was the second most identified pathogen, found in 36 (18.95%, followed by 7 cases (3.68% of methicillin-resistant Staphylococcus aureus (MRSA. The prevalence rate of MRSA in the females was higher than that in the males (RR=4.70; 95% CI, 1.09-20.18, but other demographic factors had no effect on the prevalence rate of MRSA and MRCNS.ConclusionsThe prevalence rate of these pathogens in patients with nasal bone fracture in Korea was similar to other reports. However, few studies have addressed the prevalence rate of CNS and MRCNS in accordance with risk factors or the change in prevalence according to specific prophylaxis against infectious complications. Additional research is needed on the potential connections between clinical factors and microbiological data.

    Primary cutaneous lymphomas are uncommon. This article describes the Primary Cutaneous Lymphoma Registry of the Spanish Academy of Dermatology and Venereology (AEDV) and reports on the results from the first year. Disease registry for patients with primary cutaneous lymphoma. The participating hospitals prospectively recorded data on diagnosis, treatment, tests, and disease stage for all patients with primary cutaneous lymphoma. A descriptive analysis was performed. In December 2017, the registry contained data on 639 patients (60% male) from 16 university hospitals. The most common diagnoses, in order of frequency, were mycosis fungoides/Sézary syndrome (MF/SS) (348 cases, 55%), primary cutaneous B-cell lymphoma (CBCL) (184 cases, 29%), primary cutaneous CD30 + T-cell lymphoproliferative disorder (CD30 + CLPD) (70 cases, 11%), and other types of T-cell lymphoma (37 cases, 5%). In total, 105 (16.5%) of the cases recorded were incident cases. The most common diagnosis in the MF/SS group was classic MF (77.3%). Half of the patients with MF had stage IA disease when diagnosed, and the majority were either in partial remission (32.5%) or had stable disease (33.1%). The most widely used treatments were topical corticosteroids (90.8%) and phototherapy. The most common form of primary CBCL was marginal zone lymphoma (50%). Almost all of the patients had cutaneous involvement only and nearly half had stage T1a disease. Most (76.1%) were in complete remission. The main treatments were surgery (55.4%) and radiotherapy (41.9%). The most common diagnosis in patients with CD30 + CLPD was lymphomatoid papulosis (68.8%). Most of the patients (31.4%) had stage T3b disease and half were in complete remission. The most common treatments were topical corticosteroids (68.8%) and systemic chemotherapy (32.9%). The characteristics of patients with primary cutaneous lymphoma in Spain do not differ from those described in other series in the literature. The registry will facilitate

    In B-non-Hodgkin lymphomas, Lyn and Cbp/PAG constitute the core of an oncogenic signalosome that captures the Phosphatidylinositol-3-kinase, the Spleen tyrosine kinase and the Signal transducer and activator of transcription-3 to generate pro-survival and proliferative signals. Lymphoma lines corresponding to follicular, mantle-cell and Burkitt-derived lymphomas display type-specific signalosome organizations that differentially activate PI3K, Syk and STAT3. In the follicular lymphoma line, PI3K, Syk and STAT3 were optimally activated upon association with the Lyn-Cbp/PAG signalosome, while in the Burkitt lymphoma-derived line, the association with Cbp/PAG and activation of PI3K were interfered with by the latent membrane proteins encoded by the Epstein-Barr virus. In the Jeko-1 mantle-cell line, a weak association of Syk with the Lyn-Cbp/PAG signalosome resulted in poor activation of Syk, but in those cells, as in the follicular and Burkitt-derived lines, efficient apoptosis induction by the Syk inhibitor R406 indicated that Syk is nonetheless an important prosurvival element and therefore a valuable therapeutic target. In all configurations described herein is the Lyn-Cbp/PAG signalosome independent of external signals and provides efficient means of activation for its associated lipid and protein kinases. In follicular and Burkitt-derived lines, Syk appears to be activated following binding to Cbp/PAG and no longer requires B-cell receptor-associated activation motifs for activation. Assessment of the different modalities of Lyn-Cbp/PAG signalosome organization could help in selecting the appropriate combination of kinase inhibitors to eliminate a particular type of lymphoma cells.

  14. Nasal birth trauma: a review of appropriate treatment.

    Cashman, E C

    2012-02-01

    The aetiology of nasal deformity has frequently included birth trauma. There is no consensus in the literature as to whether nasal surgery, in the form of closed reduction, is indicated in neonates. The majority of studies in the literature that advocate intervention have inadequate followup periods and there is a paucity of evidence for the adverse effects of conservative management. This case highlights the therapeutic dilemma posed by such nasal injuries in the neonate and, to the best of the authors\\' knowledge, at the time of writing, represents the earliest reported case in the literature of nasal deformity in the neonate. The term nasal deformity is used to denote deformity of the nasal pyramid, soft tissue, and septum. Three main aspects of neonatal nasal deformity are addressed including, firstly, if nasal deformity at birth needs to be addressed, secondly, if left unaltered, what the long-term effects are and, finally, if intervention alters the normal course of midfacial development.

    Full Text Available Glomangiopericytoma is a rare vascular neoplasm characterized by a pattern of prominent perivascular growth. A 72-year-old woman was admitted to our clinic complaining of nasal obstruction, frequent epistaxis, and facial pain. A reddish tumor filling the left nasal cavity was observed on endoscopy and treated with endoscopic excision. Microscopically, closely packed cells interspersed with numerous thin-walled, branching staghorn vessels were seen. Glomangiopericytoma is categorized as a borderline low malignancy tumor by WHO classification. Long-term follow-up with systemic examination is necessary due to high risk of recurrence.

The cutaneous NKT/cell lymphomas of indolent clinical behavior comprise the classical mycosis fungoides, folliculotropic mycosis fungoides, pagetoid reticulosis, granulomatous slack skin, primary cutaneous anaplastic large cell lymphoma, lymphomatoid papulosis, subcutaneous panniculitis-like T-cell lymphoma and primary cutaneous CD4+ small/medium-sized pleomorphic T-cell lymphoma. The aggressive clinical behavior cutaneous NKT/cell lymphomas include Sézary syndrome, extranodal NK/T-cell lymphoma, nasal type, primary cutaneous aggressive epidermotropic CD8+T-cell lymphoma, cutaneous gamma-delta T-cell lymphoma and primary cutaneous peripheral T-cell lymphoma, unspecified. The adult T-cell leukemia lymphoma and CD4+ CD56+ hematodermic neoplasm are considered systemic lymphomas but are addressed in this article for their initial cutaneous manifestations in a significant number of patients. The diagnosis of these processes is based on histological examination complemented by phenotypic analysis of neoplastic cells, which is essential for classification. The recommended staging is based on type and extension of cutaneous involvement, clinical conditions and histological examination of lymph nodes and organs. Hematological assessment is fundamental to characterize Sézary syndrome. The recommended therapies include exclusively cutaneous treatment, biological response modifiers and systemic chemotherapy.

  1. Adult T-cell leukemia/lymphoma treatment in Bahia, Brazil

    Directory of Open Access Journals (Sweden)

    Pedro Dantas Oliveira

    Full Text Available Abstract Background: Adult T-cell leukemia/lymphoma is a peripheral disease associated with human T-cell lymphotropic virus type 1. Treatment is carried out according to clinical type with watchful waiting being recommended for less aggressive types. Aggressive adult T-cell leukemia/lymphoma is generally treated with chemotherapy and/or antivirals. The objective of this study was to correlate the survival of patients diagnosed in Bahia, Brazil, with the therapeutic approaches employed and to evaluate what issues existed in their treatment processes. Methods: Eighty-three adult T-cell leukemia/lymphoma patients (26 smoldering, 23 chronic, 16 acute, 13 lymphoma and five primary cutaneous tumoral with available data were included in this study. Results: Complete response was achieved in seven smoldering patients with symptomatic treatment, in two with chronic disease using antivirals/chemotherapy, in one with acute disease using antivirals and in one lymphoma using the LSG15 regimen [vincristine, cyclophosphamide, doxorubicin, and prednisolone (VCAP; doxorubicin, ranimustine, and prednisolone (AMP; and vindesine, etoposide, carboplatin, and prednisolone (VECP]. Smoldering patients who received symptomatic treatment presented longer survival. Favorable chronic patients treated with antivirals presented longer survival compared to the unfavorable subtype. However, for the acute form, first-line chemotherapy was better, albeit without significance, than antivirals. Only one of the patients with lymphoma and primary cutaneous tumors responded. Conclusions: Watchful waiting associated with phototherapy represents the best option for smoldering adult T-cell leukemia/lymphoma with survival in Bahia being superior to that described in Japan. There was a trend of better results with zidovudine/interferon-alpha in favorable chronic disease. Excellent results were achieved in the lymphoma type treated with the LSG15 protocol. Patients are diagnosed late

  5. Intrapulmonary Versus Nasal Transduction of Murine Airways With GP64-pseudotyped Viral Vectors

    Directory of Open Access Journals (Sweden)

    Mayumi Oakland

    2013-01-01

    Full Text Available Persistent viral vector-mediated transgene expression in the airways requires delivery to cells with progenitor capacity and avoidance of immune responses. Previously, we observed that GP64-pseudotyped feline immunodeficiency virus (FIV-mediated gene transfer was more efficient in the nasal airways than the large airways of the murine lung. We hypothesized that in vivo gene transfer was limited by immunological and physiological barriers in the murine intrapulmonary airways. Here, we systematically investigate multiple potential barriers to lentiviral gene transfer in the airways of mice. We show that GP64-FIV vector transduced primary cultures of well-differentiated murine nasal epithelia with greater efficiency than primary cultures of murine tracheal epithelia. We further demonstrate that neutrophils, type I interferon (IFN responses, as well as T and B lymphocytes are not the major factors limiting the transduction of murine conducting airways. In addition, we observed better transduction of GP64-pseudotyped vesicular stomatitis virus (VSV in the nasal epithelia compared with the intrapulmonary airways in mice. VSVG glycoprotein pseudotyped VSV transduced intrapulmonary epithelia with similar efficiency as nasal epithelia. Our results suggest that the differential transduction efficiency of nasal versus intrapulmonary airways by FIV vector is not a result of immunological barriers or surface area, but rather differential expression of cellular factors specific for FIV vector transduction.

    1984-05-01

    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.

  7. Correlation of 18F-FDG PET/CT and Endoscopic Findings of Twin Mucosa-Associated Lymphoid Tissue (MALT) Lymphoma of the Stomach: Report of a Case

    Bahk, Yong Whee; Choi, Jin Wook

    2008-01-01

    Mucosa-associated lymphoid tissue (MALT) type lymphoma arises from extranodal marginal zone B-cell. It is etiologically associated with Helicobacter pylori infection and, hence, can be cured by antibiotic treatment. MALT type lymphoma is the most common variety of gastric lymphoma that is rare in the stomach). The published data of clinical studies on the usefulness of 18F-FDG PET in the diagnosis of MALT type lymphoma varied according to authors. Thus, the result of Hoffmann et al. was discouraging whereas a high diagnostic accuracy was reported by Ambrosini et al. The latter group further went to suggest that higher 18F-FDG uptake in gastric MALT type lymphoma would positively relate to the aggressiveness of neoplasm. The clinical studies conducted by other groups on MALT lymphomas of the stomach, lung, orbit and parotid gland and the stomach, lung, parotid gland, skin, orbit, mandible, esophagus and uterus confirmed that 18F-FDG scan is valuable

    Forty-three patients with maxillo-nasal dysplasia have been subjected to a radiographic examination of the cervical spine. In 44.2 per cent malformations of the cervical vertebrae of a minor or major type were revealed. Dysplasia of the vertebral bodies related to persistence of the chorda dorsalis, a very rare malformation, was found in six cases. No correlation between the incidence or serverity of the malformations and the degree of malocclusion of the jaws and facial deformity, characteristic of Binder syndrome, were noted. The maxillo-nasal dysplasia and the spinal malformations probably have a common cause during the embryologic stage.

    Forty-three patients with maxillo-nasal dysplasia have been subjected to a radiographic examination of the cervical spine. In 44.2 per cent malformations of the cervical vertebrae of a minor or major type were revealed. Dysplasia of the vertebral bodies related to persistence of the chorda dorsalis, a very rare malformation, was found in six cases. No correlation between the incidence or serverity of the malformations and the degree of malocclusion of the jaws and facial deformity, characteristic of Binder syndrome, were noted. The maxillo-nasal dysplasia and the spinal malformations probably have a common cause during the embryologic stage. (orig.)

    It is suggested that the brain response of a food odour sensed retro-nasally is related to satiation. The extent of retro-nasal aroma release during consumption depends on the physical structure of a food, i.e. solid foods generate a longer, more pronounced retro-nasal aroma release than liquid

    The aesthetic aspects of the cleft lip nasal deformity have been appreciated for over a century, but the functional implications have remained largely underappreciated or misunderstood. This study describes the frequency and severity of nasal obstructive symptoms among children with cleft lip and/or cleft palate, addressing the hypotheses that age, cleft type, and severity are associated with the development of nasal obstructive symptoms. Children with nonsyndromic cleft lip and/or cleft palate and a comparison group of unaffected children born from 1997 to 2003 were identified through the North Carolina Birth Defects Monitoring Program and birth certificates. Nasal airway obstruction was measured using the validated Nasal Obstruction Symptom Evaluation scale. The survey was completed by parental proxy for 176 children with cleft lip and/or cleft palate and 333 unaffected children. Nasal obstructive symptoms were more frequently reported in cleft lip with cleft palate compared with unaffected children (p cleft lip with or without alveolus and isolated cleft palate were not statistically different from unaffected children. Patients with unilateral cleft lip with cleft palate were found to be more severely affected than bilateral cases. Nasal obstruction was observed in early childhood, although severity worsened in adolescence. This population-based study reports a high prevalence of nasal obstructive symptoms in children with cleft lip and/or cleft palate based on type and severity of the cleft. The authors encourage cleft teams to consider using this or similar screening methods to identify which children may benefit from functional rhinoplasty. Risk, I.

  19. The Nature of Nasal Fricatives: Articulatory-Perceptual Characteristics and Etiologic Considerations.

    Zajac, David J

    2015-07-01

    Nasal fricatives (NFs) are unusual, maladaptive articulations used by children both with and without palatal anomalies to replace oral fricatives. Nasal fricatives vary in articulatory, aerodynamic, and acoustic-perceptual characteristics with two generally distinct types recognized. One type is produced with velopharyngeal (VP) constriction that results in turbulent nasal airflow and, frequently, tissue vibration (flutter) at the VP port. Trost (1981) described these as posterior NFs that have a distinctive snorting quality. A second type of NF is produced without significant VP constriction resulting in turbulent airflow generated at the anterior liminal valve of the nose. Of importance, both types are "active" alternative articulations in that the speaker occludes the oral cavity to direct all airflow through the nose (Harding & Grunwell, 1998). It is this oral gesture that differentiates NFs from obligatory (or passive) nasal air escape that may sound similar due to incomplete VP closure. The purpose of this article is to (1) describe the articulatory, aerodynamic, and acoustic-perceptual nature of NFs, and (2) propose a theoretical framework for the acquisition of NFs by children both with and without cleft palate.

    In recent years, there had been much interest in the concentrations of trace metals occurring in human and animal tissues and in the manner in which these concentrations may alter in malignant and other diseases. Neutron activation analysis is consider one of several methods that have been described for the determination of trace elements in biological materials. This method possesses the sensitivity and specificity necessary for the estimation at the concentrations existing naturally in most tissues, particularly when only small samples are available for analysis. The purpose of this study was to compare blood concentrations of trace elements Co, Cr, Fe, Rb, Sc, Se, Th, and Zn of lymphomas Syrian patients with those of healthy volunteers. Also, determine the relationships between trace elements concentration and the histological type of lymphomas. The blood samples were collected from 39 healthy volunteers and 49 patients with histologically confirmed lymphomas (29 Hodgkin's HL and 20 non-Hodgkin's lymphomas NHL), and analyzed to obtain the concentration of the trace elements in blood. Then, comparison between the healthy volunteers and lymphomas patients (both HL and NHL) was made to elucidate differences of the concentration distributions of the elements in blood. However, statistical analysis using Student's t test revealed significantly high concentrations of Co, Cr, Sc, and Th in lymphoma patients. Whereas Fe and Rb were found significantly decreased in lymphomas patient comparing to control group. Increasing or decreasing concentrations of Se and Zn in lymphoma patients was found not significant. Comparison between the healthy volunteers and non-Hodgkin's lymphomas patients reveled that Co, Cr, Sc, and Th were significantly elevated whereas, Rb only one trace element was decreased and all change in concentrations (elevating or decreasing) of Se and Zn were not significant. Comparison between the healthy volunteers and Hodgkin

    The most potent method for augmenting the cytocidal power of monoclonal antibody (MAb) treatment is to conjugate radionuclides to the MAb to deliver systemic radiotherapy (radioimmunotherapy; RIT). The antigen, MAb, and its epitope can make a difference in the performance of the drug. Additionally, the radionuclide, radiochemistry, chelator for radiometals and the linker between the MAb and chelator can have a major influence on the performance of drugs (radiopharmaceuticals) for RIT. Smaller radionuclide carriers, such as antibody fragments and mimics, and those used for pretargeting strategies, have been described and evaluated. All of these changes in the drugs and strategies for RIT have documented potential for improved performance and patient outcomes. RIT is a promising new therapy that should be incorporated into the management of patients with B-cell non-Hodgkin's lymphoma (NHL) soon after these patients have proven incurable. Predictable improvements using better drugs, strategies, and combinations with other drugs seem certain to make RIT integral to the management of patients with NHL, and likely lead to cure of currently incurable NHL

    There are few studies of the effects of nasal snuff and environmental factors on the risk of nasal cancer. This study aimed to investigate the impact of using nasal snuff and of other risk factors on the risk of nasal cancer in German men. A population-based case-control study was conducted in the German Federal States of Bavaria and Baden-Württemberg. Tumor registries and ear, nose and throat departments provided access to patients born in 1926 or later. Telephone interviews were conducted with 427 cases (mean age 62.1 years) and 2.401 population-based controls (mean age 60.8 years). Ever-use of nasal snuff was associated with an odds ratio (OR) for nasal cancer of 1.45 (95% confidence interval [CI] 0.88-2.38) in the total study population, whereas OR in smokers was 2.01 (95% CI 1.00-4.02) and in never smokers was 1.10 (95% CI 0.43-2.80). The OR in ever-smokers vs. never-smokers was 1.60 (95% CI 1.24-2.07), with an OR of 1.06 (95% CI 1.05-1.07) per pack-year smoked, and the risk was significantly decreased after quitting smoking. Exposure to hardwood dust for at least 1 year resulted in an OR of 2.33 (95% CI 1.40-3.91) in the total population, which was further increased in never-smokers (OR 4.89, 95% CI 1.92-12.49) in analyses stratified by smoking status. The OR for nasal cancer after exposure to organic solvents for at least 1 year was 1.53 (1.17-2.01). Ever-use of nasal sprays/nasal lavage for at least 1 month rendered an OR of 1.59 (1.04-2.44). The OR after use of insecticides in homes was 1.48 (95% CI 1.04-2.11). Smoking and exposure to hardwood dust were confirmed as risk factors for nasal carcinoma. There is evidence that exposure to organic solvents, and in-house use of insecticides could represent novel risk factors. Exposure to asbestos and use of nasal snuff were risk factors in smokers only.

    Full Text Available Despite of improved survival of premature infants, the incidence of long term pulmonary complications, mostly associated with ventilation-induced lung injury, remains high. Non invasive ventilation (NIV is able to reduce the adverse effects of mechanical ventilation. Although nasal continuous positive airway pressure (NCPAP is an effective mode of NIV, traumatic nasal complications and intolerance of the nasal interface are common. Recently high flow nasal cannula (HFNC is emerging as an efficient, better tolerated form of NIV, allowing better access to the baby’s face, which may improve nursing, feeding and bonding. The aim of this review is to discuss the available evidence of effectiveness and safety of HFNC in preterm newborns with respiratory distress syndrome (RDS. It is known that distending pressure generated by HFNC increases with increasing flow rate and decreasing infant size and varies according to the amount of leaks by nose and mouth. The effects of HFNC on lung mechanics, its clinical efficacy and safety are still insufficiently investigated. In conclusion, there is a growing evidence of the feasibility of HFNC as an alternative mode of NIV. However, further larger randomized trials are required, before being able to recommend HFNC in the treatment of moderate respiratory distress of preterm infants.

    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.

    Full Text Available BACKGROUND: Hodgkin's lymphoma has high rates of cure, but in 15% to 20% of general patients and between 35% and 40% of those in advanced stages, the disease will progress or will relapse after initial treatment. For this group, hematopoietic stem cell transplantation is considered one option of salvage therapy. OBJECTIVES: To evaluate a group of 106 patients with Hodgkin's lymphoma, who suffered relapse or who were refractory to treatment, submitted to autologous hematopoietic stem cell transplantation in a single transplant center. METHODS: A retrospective study was performed with data collected from patient charts. The analysis involved 106 classical Hodgkin's lymphoma patients who were consecutively submitted to high-dose chemotherapy followed by autologous transplants in a single institution from April 1993 to December 2006. RESULTS: The overall survival rates of this population at five and ten years were 86% and 70%, respectively. The disease-free survival was approximately 60% at five years. Four patients died of procedure-related causes but relapse of classical Hodgkin's lymphoma after transplant was the most frequent cause of death. Univariate analysis shows that sensitivity to pre-transplant treatment and hemoglobin < 10 g/dL at diagnosis had an impact on patient survival. Unlike other studies, B-type symptoms did not seem to affect overall survival. Lactic dehydrogenase and serum albumin concentrations analyzed at diagnosis did not influence patient survival either. CONCLUSION: Autologous hematopoietic stem cell transplantation is an effective treatment strategy for early and late relapse in classical Hodgkin's lymphoma for cases that were responsive to pre-transplant chemotherapy. Refractory to treatment is a sign of worse prognosis. Additionally, a hemoglobin concentration below 10 g/dL at diagnosis of Hodgkin's lymphoma has a negative impact on the survival of patients after transplant. As far as we know this relationship has not

  10. Challenges and Opportunities of MicroRNAs in Lymphomas

    Directory of Open Access Journals (Sweden)

    Giacoma De Tullio

    2014-09-01

    Full Text Available MicroRNAs (miRNAs are small non-coding RNAs that control the expression of many target messenger RNAs (mRNAs involved in normal cell functions (differentiation, proliferation and apoptosis. Consequently their aberrant expression and/or functions are related to pathogenesis of many human diseases including cancers. Haematopoiesis is a highly regulated process controlled by a complex network of molecular mechanisms that simultaneously regulate commitment, differentiation, proliferation, and apoptosis of hematopoietic stem cells (HSC. Alterations on this network could affect the normal haematopoiesis, leading to the development of haematological malignancies such as lymphomas. The incidence of lymphomas is rising and a significant proportion of patients are refractory to standard therapies. Accurate diagnosis, prognosis and therapy still require additional markers to be used for diagnostic and prognostic purpose and evaluation of clinical outcome. The dysregulated expression or function of miRNAs in various types of lymphomas has been associated with lymphoma pathogenesis. Indeed, many recent findings suggest that almost all lymphomas seem to have a distinct and specific miRNA profile and some miRNAs are related to therapy resistance or have a distinct kinetics during therapy. MiRNAs are easily detectable in fresh or paraffin-embedded diagnostic tissue and serum where they are highly stable and quantifiable within the diagnostic laboratory at each consultation. Accordingly they could be specific biomarkers for lymphoma diagnosis, as well as useful for evaluating prognosis or disease response to the therapy, especially for evaluation of early relapse detection and for greatly assisting clinical decisions making. Here we summarize the current knowledge on the role of miRNAs in normal and aberrant lymphopoiesis in order to highlight their clinical value as specific diagnosis and prognosis markers of lymphoid malignancies or for prediction of therapy

    The endoscopic approach for pituitary tumors is a recent innovation and is said to reduce the nasal trauma associated with transnasal transsphenoidal surgery. The authors assessed the temporal changes in the rhinological symptoms following endoscopic transsphenoidal surgery for pituitary lesions, using the General Nasal Patient Inventory (GNPI). The GNPI was administered to 88 consecutive patients undergoing endoscopic transsphenoidal surgery at 3 time points (presurgery, 3-6 months postsurgery, and at final follow-up). The total GNPI score and the scores for the individual GNPI questions were calculated and differences between groups were assessed once before surgery, several months after surgery, and at final follow-up. Of a maximum possible score of 135, the mean GNPI score at 3-6 months postsurgery was only 12.9 ± 12 and was not significantly different from the preoperative score (10.4 ± 13) or final follow-up score (10.3 ± 10). Patients with functioning tumors had higher GNPI scores than those with nonfunctioning tumors for each of these time points (p surgery, with partial recovery (nasal sores and bleeding) or complete recovery (nasal blockage, painful sinuses, and unpleasant nasal smell) by final follow-up (p transsphenoidal surgery is a well-tolerated minimally invasive procedure for pituitary fossa lesions. Overall patient-assessed nasal symptoms do not change, but some individual symptoms may show a mild worsening or overall improvement.

    Computational fluid dynamics (CFD) is a mathematical tool to analyse airflow. As currently CFD is not a usual tool for rhinologists, a group of engineers in collaboration with experts in Rhinology have developed a very intuitive CFD software. The program MECOMLAND ® only required snapshots from the patient's cross-sectional (tomographic) images, being the output those results originated by CFD, such as airflow distributions, velocity profiles, pressure, temperature, or wall shear stress. This is useful complementary information to cover diagnosis, prognosis, or follow-up of nasal pathologies based on quantitative magnitudes linked to airflow. In addition, the user-friendly environment NOSELAND ® helps the medical assessment significantly in the post-processing phase with dynamic reports using a 3D endoscopic view. Specialists in Rhinology have been asked for a more intuitive, simple, powerful CFD software to offer more quality and precision in their work to evaluate the nasal airflow. We present MECOMLAND ® and NOSELAND ® which have all the expected characteristics to fulfil this demand and offer a proper assessment with the maximum of quality plus safety for the patient. These programs represent a non-invasive, low-cost (as the CT scan is already performed in every patient) alternative for the functional study of the difficult rhinologic case. To validate the software, we studied two groups of patients from the Ear Nose Throat clinic, a first group with normal noses and a second group presenting septal deviations. Wall shear stresses are lower in the cases of normal noses in comparison with those for septal deviation. Besides, velocity field distributions, pressure drop between nasopharynx and the ambient, and flow rates in each nostril were different among the nasal cavities in the two groups. These software modules open up a promising future to simulate the nasal airflow behaviour in virtual surgery intervention scenarios under different pressure or

    Multiple lymphomatous polyposis (HLP) is an unusual form of non-Hodgkin's lymphoma characterized by polyps throughout the gastrointestinal tract. It has been reported that most MLP are observed in cases with mantle cell lymphoma of B-cell type. We herein present a case of a 66-year-old man with adult T-cell leukemia/lymphoma (ATLL). Colonoscopy revealed MLP throughout the colon and histopathological findings of ATLL cell infiltration. The patient died despite combination of chemotherapy. The literature of manifestations of colonic involvement of ATLL is reviewed and the importance of endoscopic evaluation to differentiate ATLL intestinal lesions from opportunistic infectious enterocolitis is discussed.

    Nodal marginal zone lymphoma (NMZL) is a rare type of B-cell non-Hodgkin lymphoma. This study assessed the clinical features of 56 patients with NMZL in comparison to 46 patients with follicular lymphoma (FL). Patients with NMZL and FL had a largely similar clinical presentation, but patients with FL had a higher disease stage at presentation, more frequent abdominal lymphadenopathy and bone marrow involvement, and showed more common transformation into diffuse large B-cell lymphoma (DLBCL) during the course of disease. Overall survival and event-free survival were similar for patients with NMZL and FL, but factors associated with worse prognosis differed between the two groups. Transformation into DLBCL was associated with a significantly poorer outcome in both groups, but the phenotypes were different: DLBCL arising in FL was mainly of germinal center B-cell phenotype, whereas DLBCL arising in NMZL was mainly of non-germinal center B-cell phenotype.

    The interest of this study has been to learn the bio demographic characteristics of the Hodgkin lymphoma in our surrounding in accord with different clinical statistics that are considered of interest taken as references the results obtained in each on them. The clinical histories of the patients were evaluated retrospectively with diagnosis of Hodgkin, and registered in the national Institute of Oncology in Havana during the years 1980-1985 (group1) and the 1990-1995 (group 2). The sample was constituted by 242 patients (156 group 1, 86 group 2). The disease was slightly more frequent in males (1.3:1) in both groups. The biggest incidence fell upon the patients under 30 year of age with 74 (31%) in the group 1, and 41 (17%) group 2; followed by the group of patients between 30 and 49 years old with 24% in group 1 and 12 in group 2. The histological subtype most frequently found was the mixed cellularity 55% of the patients followed by nodular sclerosis in 32% clinical stage III was the most frequent with 138 patients (55%) the cervical adenopathy was the most consulted symptom referred by 199 (82%) of the patients. The ionizing radiation as only treatment were used in 115 patients (48%) while 80 (33%) were treated in conjunction with polychemotherapy, and in 40 (17%) polychemotherapy was used alone. A total of 204 (84%) patients showed complete remission when ended the initial treatment while 96 (40.9%) showed a relapse and 55 (62%) of them obtained a second CR. Until the last news, there are 196 (81%) alive patients and 43 (18%) dead. (The author)

    Optimal lymphoma management requires accurate pretreatment staging and reliable assessment of response, both during and after therapy. Positron emission tomography with computerized tomography (PET/CT) combines functional and anatomical imaging and provides the most sensitive and accurate methods...... for lymphoma imaging. New guidelines for lymphoma imaging and recently revised criteria for lymphoma staging and response assessment recommend PET/CT staging, treatment monitoring, and response evaluation in all FDG-avid lymphomas, while CT remains the method of choice for non-FDG-avid histologies. Since...... interim PET imaging has high prognostic value in lymphoma, a number of trials investigate PET-based, response-adapted therapy for non-Hodgkin lymphomas (NHL). PET response is the main determinant of response according to the new response criteria, but PET/CT has little or no role in routine surveillance...

    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

    Treatment results were reviewed in 473 consecutively staged and treated patients at the National Cancer Institute over a 22-year period from 1953 to 1975. Responses correlated with histologic pattern and stage of disease. Complete responses to radiotherapy were frequent in nodular lymphoma patients. Similar treatment regimens were less effective in diffuse lymphoma patients. Using chemotherapy or combined modality approaches, complete responses were obtained in a high proportion of advanced nodular disease patients. Patients with nodular lymphoma tend to have higher complete response rates and longer survivals than their counterparts with diffuse histologic types. Patients with nodular lymphocytic lymphoma had a better survival than those with mixed or ''histiocytic'' histologic types. Patients with diffuse well differentiated lymphocytic lymphoma survived significantly longer than patients with other diffuse histologic types. Percentage and prominence of nodularity were not of prognostic significance in those patients with combined nodular and diffuse patterns of disease. When compared by histologic type, patient sex did not appear to be an important prognostic factor. The presence of B-symptoms was associated with a poorer survival in patients with nodular disease and in patients with diffuse disease. Over the years of this study, survival appears to have improved in each histologic subtype except diffuse poorly differentiated lymphoma

    Full Text Available Malignant lymphoma may occur in the oral cavity and oropharynx, but is most commonly located in Waldeyer's ring, particularly in the palatine and lingual tonsil. The occurrence of malignant lymphoma in the tongue is very rare. Clinical features are nonspecific ulcerative lesions that do not heal. In the literature, the majority of casesare non-Hodgkin’s lymphoma, diffuse large B cell type; however T-cell phenotype also may occur. We describe a 60-year-old man who presented with an ulcerative mass in the left lateral aspect of his tongue, unresponsive to medical therapy. After tissue biopsy, histopathological and immunohistochemical analyses confirmed a diagnosis of non-Hodgkin’s lymphoma, diffuse large B cell type.

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

    Full Text Available Introduction: Solitary fibrous tumours (SFTs of the nose and paranasal sinuses are extremely rare.These were originally described as neoplasms of the pleura originating from spindle cells. It is further sub-classified as a benign type of mesothelial tumour. Its occurrence in many extra pleural sites have been reported earlier, mainly in the liver, parapharyngeal space, sublingual glands, tongue, parotid gland, thyroid, periorbital region, and very occasionally in the nose and  paranasal sinus area.   Case Report: A 28-year-old man with a 6 month history of persistent progressive left nasal obstruction and watering of the left eye is reported. Further imaging by CT and MRI revealed a large, left-sided, highly vascular, nasal cavity mass (Fig 1,2,3,4 pushing laterally on the medial wall of the maxilla. The patient underwent a lateral rhinotomy, which proceeded with the excision of the mass. Histopathological analysis of the specimen was consistent with SFT.   Conclusion:  This case is reported to develop insights regarding diagnosis and management of such rare tumours.

    Nasal mucociliary function was evaluated by nasal scintigraphy in normal subjects. A microdrop of HSA or saline labelled with 99m Tc was dripped into the middle part of each middle meatus in the nasal cavity and its clearance was observed by scinticamera. The accumulated concentration of RI was determined every 30 seconds for 10 minutes. The changes of accumulated concentration were studied, and a curve of decreasing RI-counts was obtained, with the 'clearance rate' defined as 100% for the count at the initial 30 seconds and 'half time' as the time when radioactivity was reduced to one half the initial count. Nasal resistance was measured by rhinomanometry with the oscillation method. In nonsmokers, 10μl of saline was cleared (78.0±10.4%) significantly faster than 10μl of HSA (59.9±24.6%), and there was no significant difference in the clearance between 10μl and 5μl of HSA (55.9±27.7%). In smakers, the mucociliary clearance of 10μl of HSA and saline was significantly lower than in nonsmokers. The clearance of 10μl of HSA reflects a pathological state much better than that of 5μl. In nonsmokers, there is a significant negative correlation between nasal resistance and clearance rate, suggesting that the more patent the nose, the faster the mucociliary clearance. When both nostrils were closed, the clearance rate was significantly depressed. When one nostril was closed, there was no significant effect on clearance. Nasal resistance was decreased by exercise with a bicycle ergometer. Nasal mucociliary clearance was slightly decreased after exercise but not significantly so. (J.P.N.)

    Full Text Available Background Pathogens in the nasal cavity during nasal surgery could lead to a systemicinfectious condition, such as bacteremia, nosocomial infection, or toxic shock syndrome.However, there is no research about the prevalence of nasal carriage in patients with nasalbone fracture.Methods This was a prospective, double-blind, randomized study about the rate of nasalcarriage in 200 patients with nasal bone fracture in Korea. Nasal secretions were taken fromboth the middle nasal meatus and colonized. All analyses were carried out using SPSS software.Results Pathogens were identified in 178 of the 200 cases. Coagulase-negative staphylococci(CNS were the most cultured bacteria in 127 (66.84% of the 190 total patients after excluding10 cases of contaminated samples, and methicillin-resistant coagulase-negative staphylococci(MRCNS were found in 48 (25.26%. Staphylococcus aureus was the second mostidentified pathogen, found in 36 (18.95%, followed by 7 cases (3.68% of methicillin-resistantStaphylococcus aureus (MRSA. The prevalence rate of MRSA in the females was higher thanthat in the males (RR=4.70; 95% CI, 1.09-20.18, but other demographic factors had no effecton the prevalence rate of MRSA and MRCNS.Conclusions The prevalence rate of these pathogens in patients with nasal bone fracture inKorea was similar to other reports. However, few studies have addressed the prevalence rateof CNS and MRCNS in accordance with risk factors or the change in prevalence according tospecific prophylaxis against infectious complications. Additional research is needed on thepotential connections between clinical factors and microbiological data.

  7. Fertility in female survivors of Hodgkin's lymphoma

    2012-01-01

    Full Text Available Currently, Hodgkin's lymphoma is one of the most curable types of cancer. Patients are often young and so the long-term morbidities of treatment have become of increasing concern. Among these, infertility is one of the most challenging consequences for patients in reproductive age. Premature ovarian failure in premenopausal women is a serious long-term sequel of the toxicity of chemotherapy. The main consequence of this syndrome is infertility, but women also present other symptoms related to estrogen deprivation. Different rates of impaired gonadal function are reported, depending on the patient's age, stage of disease, dose and intensity of chemotherapy and the use of radiation therapy. The most established strategy in female infertility is cryopreservation of embryos after in vitro fertilization. Additionally, the use of oral contraceptives or gonadotropinreleasing hormone analogs (GnRH-a during treatment is under study. This review will provide a general overview of the main studies conducted to evaluate the infertility rate among female Hodgkin's lymphoma survivors and risk factors associated to treatment, different end-point definitions for evaluating fertility and also a brief description of the available strategies for fertility preservation.

    2013-01-01

    Full Text Available Introduction. Sometimes it is not easy to clinically recognize subtle differences between intraocular lymphoma and noninfectious uveitis. The most common lymphoma subtype involving the eye is B-cell lymphoma. Case report. We presented two patients aged 59 and 58 years with infiltration of the subretinal space with a large B-cell non-Hodgkin intraocular lymphoma. The patients originally had clinically masked syndrome in the form of intermediate uveitis. As it was a corticosteroid-resistant uveitis, we focused on the possible diagnosis of neoplastic causes of this syndrome. During hospitalization, the neurological symptoms emerged and multiple subretinal changes accompanied by yellowish white patches of retinal pigment epithelium with signs of vitritis, which made us suspect the intraocular lymphoma. Endocranial magnetic resonance imaging established tumorous infiltration in the region of the left hemisphere of the cerebellum. The histopathological finding confirmed the diagnosis of large B-cell non-Hodgkin lymphoma of risk moderate degree, immunoblast - centroblast cytological type. The other patient had clinical chronic uveitis accompanied by yellowish shaped white echographic changes of the retina and localized changes in the level of the subretina. The diagnosis of lymphoma was made by brain biopsy. Conclusion. Uveitis masquerade syndrome should be considered in all patients over 40 years with idiopathic steroid-resistant uveitis. Treatment begun on time can affect the course and improve the prognosis of uveitis masquerade syndrome (UMS and systemic disease.

    Lymphoma is a complex disease that arises from cells of the immune system with an intricate pathology. While lymphoma may be classified as Hodgkin or non-Hodgkin, each type of tumor is genetically and phenotypically different and highly invasive tissue biopsies are the only method to investigate these differences. Noninvasive imaging strategies, such as immunoPET, can provide a vital insight into disease staging, monitoring treatment response in patients, and dose planning in radioimmunotherapy. ImmunoPET imaging with radiolabeled antibody-based tracers may also assist physicians in optimizing treatment strategies and enhancing patient stratification. Currently, there are two common biomarkers for molecular imaging of lymphoma, CD20 and CD30, both of which have been considered for investigation in preclinical imaging studies. In this review, we examine the current status of both preclinical and clinical imaging of lymphoma using radiolabeled antibodies. Additionally, we briefly investigate the role of radiolabeled antibodies in lymphoma therapy. As radiolabeled antibodies play critical roles in both imaging and therapy of lymphoma, the development of novel antibodies and the discovery of new biomarkers may greatly affect lymphoma imaging and therapy in the future.

    The place of positron emission tomography (PET) in the evaluation of diffuse at big cells B lymphomas and hodgkin lymphomas is validated. The clinical impact of the PET registered in end of therapy development is indisputable. recommendations must be followed for images interpretation. The PET is strongly recommended during the first evaluation of the disease because it is a reference examination that makes easy the interpretation at the end of the therapy and allows to evaluate the extension of the disease with a sensitivity and a specificity superior to the computerized tomography. the prognosis value of intermediate evaluations appears certain in the diffuse at big cells B lymphomas and the hodgkin lymphomas but the impact of an early therapy change induced by PET is still to determine. The criteria of interpretation of early evaluations are to standardize. for the other types of lymphomas, the PET can have an interest to confirm the the localized stages, especially for the follicular lymphomas and direct the biopsy for a patient ill of a low range lymphoma suspect of aggressive change.

    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.

    We performed pancreatoduodenectomy in a 41-year-old man with pancreatic malignant lymphoma, who began to have obstructive jaundice and in whom imaging showed a tumor of the head of the pancreas with extrapancreatic growth. The tumor was 8 x 8.5 x 4 cm in size. The histopathological findings of the tumor indicated a malignant lymphoma, non-Hodgkin, diffuse large cell type. The patient was discharged after receiving nine courses of postoperative chemotherapy with VEPA. It is very important in determing the surgical indication to preoperatively differentiate malignant lymphoma from pancreatic cancer, since malignant lymphoma originating from the gastrointestinal organs can, in some cases, be almost completely repaired if the tumor is removed in the early stage. Thus, it is possible to achieve effective multidisciplinary treatment for malignant lymphoma by performing closer preoperative examinations and taking into consideration the possibility of the existence of malignant lymphoma. This paper discusses the details of the imaging necessary to differentiate pancreatic malignant lymphoma. (author)

    In nodal diffuse large B-cell lymphoma, the search for double-hit with MYC and BCL2 and/or BCL6 rearrangements or for dual expression of BCL2 and MYC defines subgroups of patients with altered prognosis that has not been evaluated in primary cutaneous large B-cell lymphoma. Our objectives were to assess the double-hit and dual expressor status in a cohort of 44 patients with primary cutaneous large B-cell lymphoma according to the histological subtype and to evaluate their prognosis relevance. The 44 cases defined by the presence of more than 80% of large B-cells in the dermis corresponded to 21 primary cutaneous follicle centre lymphoma with large cell morphology and 23 primary cutaneous diffuse large B-cell lymphoma, leg type. Thirty-one cases (70%) expressed BCL2 and 29 (66%) expressed MYC. Dual expressor profile was observed in 25 cases (57%) of either subtypes (n = 6 or n = 19, respectively). Only one primary cutaneous follicle centre lymphoma, large-cell case had a double-hit status (2%). Specific survival was significantly worse in primary cutaneous diffuse large B-cell lymphoma, leg type than in primary cutaneous follicle centre lymphoma, large cell (p = 0.021) and for the dual expressor primary cutaneous large B-cell lymphoma group (p = 0.030). Both overall survival and specific survival were worse for patients belonging to the dual expressor primary cutaneous diffuse large B-cell lymphoma, leg type subgroup (p = 0.001 and p = 0.046, respectively). Expression of either MYC and/or BCL2 negatively impacted overall survival (p = 0.017 and p = 0.018 respectively). As the differential diagnosis between primary cutaneous follicle centre lymphoma, large cell and primary cutaneous diffuse large B-cell lymphoma, leg type has a major impact on prognosis, dual-expression of BCL2 and MYC may represent a new diagnostic criterion for primary cutaneous diffuse large B-cell lymphoma, leg type subtype and further identifies patients with

    Full Text Available Angiofibromas are rare vascular tumors which originate predominantly in the nasopharynx and occur typically in male adolescents. Extranasopharyngeal sites such as nasal cavity and paranasal sinuses are less frequent. This review article was undertaken to evaluate the incidence, clinical features and management of extranasopharyngeal angiofibromas originating exclusivelly from nasal cavity structures. Our focus of interest was to evaluate the significance of immunohistochemical analysis in diagnosis of such extremely rare neoplasms. In the PubMed and Google Search, we found only 39 cases of nasal angifibroma, 27 males and 12 females from 1980 to 2012. The most prevalent site of origin was nasal septum, followed by inferior and middle turbinate. The commonest symptoms were nasal obstruction and epistaxis. Nasal angiofibromas are clinically distinct from nasopharyneal angiofibromas and can therefore be misdiagnosed. The differential diagnosis includes other vascular lesions, such as lobular capillary hemangioma and sinonasal-type hemangiopericytoma. Although immunohistochemistry is not necessary for differentiation between angiofibroma and capillary hemangioma, that diagnostic procedure may be helpful in distinction from sinonasal hemangiopericytoma. As an ilustration for immunohistochemical analysis, we presented a case of an elderly woman with tumor arising from the middle turbinate, diagnosed as angiofibroma. The staining was positive for CD34, CD31, factor VIII, vimentin and smooth muscle α-actin, and negative for desmin.

The naturally arising tumors included an immunoblastic sarcoma and an undifferentiated lymphoma.

Some of these animals developed such opportunistic infections as cytomegalovirus hepatitis and ...

    Full Text Available As neoplasias nasais são bastante raras. Os tumores mais observados na cavidade nasal são papilomas epiteliais, angiomas, carcinoma de células transicionais, carcinoma pavimentoso e adenocarcinoma. O adenoma pleomórfico pertence ao grupo de tumores que aparecem com menor freqüência na fossa nasal, e é o tumor benigno glandular mais comum originado na cabeça e pescoço. A apresentação clínica típica dos pacientes com adenoma pleomórfico do septo nasal é de obstrução nasal unilateral, epistaxe e massa indolor na cavidade nasal. Em vista da raridade da apresentação clínica do adenoma pleomórfico nesta localização, os autores descrevem um caso de adenoma pleomórfico nasal em um paciente do sexo masculino, com 69 anos de idade, onde relatam os achados clínicos, critérios diagnósticos, tratamento, prognóstico e revisão da literatura.Nasal tumours are very rare. The neoplasms most frequently seen in the nasal cavity are epithelial papillomas, angiomas, transitional cells carcinoma, pavement carcinoma and adenocarcinoma. The pleomorphic adenoma belongs to the group of tumours less commonly observed in the nasal cavity, and is the most common head and neck benign glandular tumour. The typical clinical presentation of the nasal pleomorphic adenoma is of unilateral nasal obstruction, epistaxis and a painless mass in the nasal cavity. The authors reported an adenoma pleomorphic case that highlights itself by its unusual nasal presentation in the nasal septum of a 45-year-old male patient who was submitted to surgical treatment, and discuss the clinical findings, diagnostic criteria, treatment, prognosis and literature review.
