    Posttransplantation lymphoproliferative disorder (PTLD) is a recognized and extremely morbid complication of solid organ transplantation, but central nervous system involvement, particularly in isolation, is rare. There are no standardized treatment strategies for PTLD, though commonly used strategies include reduction of immunosuppression, chemotherapy, rituximab, radiation, and surgery. We present a case of an unusual morphologic variant of primary central nervous system PTLD with successful response to rituximab and cranial radiation. A 69-year-old Asian male, who underwent postrenal transplant nine years earlier, presented with a one-month history of new onset seizure activity. His evaluation revealed multiple brain lesions on magnetic resonance imaging (MRI), as well as serologic and cerebrospinal fluid studies which were positive for Epstein-Barr Virus (EBV) infection. Ultimately, he underwent craniotomy with tissue biopsy with the final pathology report showing posttransplant lymphoproliferative disorder, polymorphic type. The patient was managed with reduction in immunosuppression, rituximab therapy, and cranial radiation treatments. He had demonstrated marked improvement in his neurologic function and was ultimately discharged to inpatient rehabilitation facility. PMID:28116196

    Posttransplantation lymphoproliferative disorder (PTLD) is a serious complication following solid organ transplantation that has been linked to Epstein-Barr virus (EBV) infection. The aim of this article was to describe a single-center experience with the multiplicity of clinical presentations of PTLD. Among 350 liver transplantations performed in 303 children, 13 survivor children displayed a histological diagnosis of PTLD (13/242 survivors; 5.4%). The age at diagnosis ranged from 12 to 258 months (median, 47), and the time from transplantation ranged from 1 to 84 months (median, 13). Ten of these children (76.9%) were EBV-naïve prior to transplantation. Fever was present in all cases. The clinical signs at presentation were anemia (92.3%), diarrhea and vomiting (69.2%), recurrent upper airway infections (38.4%), Waldeyer ring lymphoid tissue hypertrophy (23.0%), abdominal mass lesions (30.7%), massive cervical and mediastinal adenopathy (15.3%), or gastrointestinal and respiratory symptoms (30.7%). One child developed fulminant hepatic allograft failure secondary to graft involvement by PTLD. Polymorphic PTLD was diagnosed in 6 patients; 7 had the diagnosis of lymphoma. Treatment consisted of stopping immunosuppression as well as starting intravenous gancyclovir and anti-CD20 monoclonal antibody therapy. The mortality rate was 53.8%. The clinical presentation of PTLD varied from fever of unknown origin to fulminant hepatic failure. The other symptoms that may be linked to the diagnosis of PTLD are pancytopenia, tonsil and adenoid hypertrophy, cervical or mediastinal lymph node enlargement, as well as abdominal masses. Despite numerous advances, the optimal treatment approach for PTLD is not completely known and the mortality rate is still high.

    Posttransplant lymphoproliferative disorder (PTLD) is a known complication of organ transplantation, but musculoskeletal involvement of PTLD remains very rare. We present a case of recurrent PTLD of the bone in a heart transplant patient that was misdiagnosed as gout for several years. There are only a few cases of osseous PTLD in the literature, and we hope to better characterize its imaging findings on multiple imaging modalities. (orig.)

    Full Text Available A 50-year-old male patient presented with fever, epistaxis and multiple lymphadenopathy since 15 days. In the light of the above presentation a complete workup was initiated to exclude common conditions like tuberculosis, acquired immunodeficiency syndrome, lymphoid malignancy and sarcoidosis. After excluding common conditions a biopsy of cervical lymph node demonstrated reactive lymphadenitis with paracortical hyperplasia. Immunohistochemistry demonstrated double negative lymphocytes (CD4-, CD8-. A diagnosis of autoimmune lymphoproliferative disorder syndrome (ALPS (probable was made and patient was started on 1 mg/kg of steroids. Patient showed a dramatic improvement with respect to general wellbeing, fever and regression of lymphadenopathy. This entity of ALPS has been recently identified and classified; most of the reports are from the pediatric population. To the best of our knowledge ours is one of the few cases of this entity being reported in an adult patient from India.

    Post-transplant lymphoproliferative disorder (PTLD) occasionally presents as Burkitt lymphoma/L3 leukaemia (BLL). We reviewed records of cases of PTLD post-cardiac transplantation (1990-2007) occurring in our unit. There were 15 episodes in 13 patients including four cases of EBV-driven Burkitt-type disease with t(8;14) translocations presenting with advanced stage disease. The first case was treated with a variety of low dose chemotherapy combinations. Despite problems during therapy he obtained complete remission, but died from complications of pre-existing cardiac allograft vasculopathy 7 months later. The subsequent three cases were treated with a UKCCSG low stage lymphoma protocol, NHL 9001 and Rituximab. They remain in complete remission. In the context of PTLD the prognostic significance of advanced stage EBV-driven BLL with the t(8;14) translocation may be different to that in immunocompetent children. (c) 2009 Wiley-Liss, Inc.

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

    The success rate of pediatric liver transplantation has improved in recent years. Advances in immunosuppression have reduced the risk of rejection, but have enhanced the risk of posttransplant lymphoproliferative disorder (PTLD). Since 1994, we have performed 197 orthotopic liver transplantations in 157 recipients younger than 15 years. Herein we have performed a retrospective study to review the incidence and clinical characteristics, along with the treatment and outcomes of PTLD diagnosed over this 14-year experience. We documented 8 cases of PTLD (5%), half of which occurred during the first 2 years posttransplantation; 5 presented with abdominal involvement and 2 with thoracic masses. The histological findings showed lymphoma in 6 cases. All were treated with reduction of immunosuppression and 2 received Rituximab. Three patients died, a mortality rate of 37.5%. One subject experienced rejection, and the others responded to treatment. PTLD is a life-threatening condition that requires a high index of suspicion, appropriate imaging, biopsy diagnosis, and prompt treatment to achieve positive results. Quantitative monitoring of Epstein-Barr virus load may be useful to detect a high-risk population.

  8. Pure Red Cell Aplasia and Lymphoproliferative Disorders: An Infrequent Association

    Full Text Available Pure red cell aplasia (PRCA is a rare bone marrow failure syndrome defined by a progressive normocytic anaemia and reticulocytopenia without leukocytopenia and thrombocytopenia. Secondary PRCA can be associated with various haematological disorders, such as chronic lymphocytic leukaemia (CLL or non-Hodgkin lymphoma (NHL. The aim of the present review is to investigate the infrequent association between PRCA and lymphoproliferative disorders. PRCA might precede the appearance of lymphoma, may present simultaneously with the lymphoid neoplastic disease, or might appear following the lymphomatic disorder. Possible pathophysiological molecular mechanisms to explain the rare association between PRCA and lymphoproliferative disorders are reported. Most cases of PRCA are presumed to be autoimmune mediated by antibodies against either erythroblasts or erythropoietin, by T-cells secreting factors selectively inhibiting erythroid colonies in the bone marrow or by NK cells directly lysing erythroblasts. Finally, focus is given to the therapeutical approach, as several treatment regimens have failed for PRCA. Immunosuppressive therapy and/or chemotherapy are effective for improving anaemia in the majority of patients with lymphoma-associated PRCA. Further investigation is required to define the pathophysiology of PRCA at a molecular level and to provide convincing evidence why it might appear as a rare complication of lymphoproliferative disorders.

    Hepatitis C virus (HCV) is a global health problem affecting 3% of the world's population (about 180 million) and a cause of both hepatic and extrahepatic diseases. B-cell lymphoproliferative disorders, whose prototype is mixed cryoglobulinemia, represent the most closely related as well as the most investigated HCV-related extrahepatic disorder. The association between extrahepatic (lymphoma) as well as hepatic malignancies (hepatocellular carcinoma) has justified the inclusion of HCV among human cancer viruses. HCV-associated manifestations also include porphyria cutanea tarda,lichen planus, nephropathies, thyreopathies, sicca syndrome, idiopathic pulmonary fibrosis, diabetes,chronic polyarthritis, sexual dysfunctions, cardiopathy/atherosclerosis, and psychopathological disorders.A pathogenetic link between HCV virus and some lymphoproliferative disorders was confirmed by their responsiveness to antiviral therapy, which is now considered the first choice treatment. The aim of the present paper is to provide an overview of extrahepatic manifestations of HCV infection with particular attention to B-cell lymphoproliferative disorders. Available pathogenetic hypotheses and suggestions about the most appropriate, currently available, therapeutic approaches will also be discussed.

    Full Text Available One well recognized and potentially serious complication of chronic immunosuppression in organ transplant recipients is post-transplantation lymphoproliferative disorders (PTLD. This accounts for 20% of all malignancies in transplant recipients, which is four times higher than the general population1,2. The diagnosis of PTLD is often difficult, due to various manifestations resulting in late diagnosis. We report an unusual presentation of PTLD in a pediatric patient where the diagnosis was achieved only after extensive investigation.

    Lymphoproliferative disorder is a well-recognized complication of lung transplantation. Risk factors include Epstein-Barr virus infection and immunosuppression. The gastrointestinal manifestations of post-transplant lymphoproliferative disorder in lung transplant recipients have not been fully characterized. Case presentation and 16 previously reported cases of post-transplant lymphoproliferative disorder with gastrointestinal involvement are reviewed. Patient ages ranged from 25 to 65 (median, 52) years. Median time from lung transplantation to onset of posttransplant lymphoproliferative disorder was 36 (range, 1-109) months; 35 percent of cases (6/17) occurred within 18 months; Eighty-eight percent of patients (15/17) had positive Epstein-Barr virus serology before transplantation. In five patients (29 percent), the posttransplant lymphoproliferative disorder also involved sites other than the gastrointestinal tract. The most common gastrointestinal site of posttransplant lymphoproliferative disorder was the colon, followed by the small intestine and stomach. Clinical features included abdominal pain, nausea, and bloody diarrhea. Diagnosis was based on typical pathologic changes on gastrointestinal tract biopsy obtained mainly by colonoscopy. Treatment included a reduction in the immunosuppressive regimen in 15 of 17 cases (88 percent) and surgical resection in 10 (59 percent). One patient was untreated. Seven of 16 patients (44 percent) responded to treatment and 9 patients died. Median time from onset of posttransplant lymphoproliferative disorder to death was 70 (range, 10-85) days. Posttransplant lymphoproliferative disorder with gastrointestinal involvement is a unique entity that should be considered in all Epstein-Barr-Virus-positive lung transplant recipients who present with abdominal symptoms. Although immunosuppressive modulation and resection can lead to remission, the risk of death is 50 percent.

    Full Text Available Posttransplant lymphoproliferative disorder (PTLD is a well-described complication of solid organ and bone marrow transplants. The most common presentation is intra-abdominal lymphadenopathy or single or multiple intraparenchymal masses involving the liver, spleen, or kidneys. Here we describe the imaging and pathology findings of an unusual case of PTLD appearing as an intramuscular forearm lesion in a pediatric male. The manifestation of PTLD as an isolated upper extremity mass in a pediatric patient has to our knowledge not been described.

    value of 9.0 (range 2.0-18.6) and 17.4 (range 2.6-26.4). Posttransplant lymphoproliferative disorder often had an atypical presentation on positron emission tomography with high incidence of extranodal involvement. In conclusion, from these data, we can conclude that 18F-fluorodeoxyglucose-positron emission tomography is highly sensitive for detecting posttransplant lymphoproliferative disorder and has an excellent ability to differentiate posttransplant lymphoproliferative disorder from non-malignant diseases.

    Post-transplant lymphoproliferative disorders (PTLD) are long-term complications of immunosuppression after solid organ/bone marrow transplantation. In most cases, PTLD arises as a result of primary or reactivated Epstein-Barr virus infection in a host with impaired cellular immunity. PTLD is most often seen in the gastrointestinal tract, although it has also been reported in other organ systems, including the central nervous system and, rarely, in the head and neck. It is characterized histologically by abnormal lymphoid cell proliferation. Although many forms of PTLD do not meet all of the histologic criteria of lymphoma, they often behave clinically in a malignant fashion if left untreated. We present 3 rare cases of PTLD manifesting in the oral cavity as mucosal masses after solid organ transplantation. There are only 8 published reports of PTLD in the literature presenting as oral lesions. The clinical, pathologic, and therapeutic spectra of PTLD are discussed.

    Objective To review the recent studies about microRNAs and advances in malignant lymphoproliferative disorders.Data sources Published articles (2001-2006) about microRNAs and malignant iymphoproliferative disorders were selected using MEDLINE.Study selection After independent review by two observers, 43 of 421 originally identified articles were selected that specifically addressed the stated purpose.Results Two observers independently assessed studies using explicit methodological criteria for evaluating microRNAs in malignant lymphoproliferative disorders. Recent work has revealed a class of small noncoding RNA species,microRNAs, which affect various biological processes. MicroRNAs inhibit the expression of protein encoding genes at the posttranscriptional level in a variety of eukaryotic organisms. In this review, we focused on the biogenetic pathways of microRNAs (miR-15a, miR-16-1, miR-155, miR-17-92 cluster, miR-142) and discussed the implications for human malignant lymphoproliferative disorders.Conclusions microRNAs are involved in tumorigenesis and mediate gene regulation as a fundamental genetic program at the posttranscriptional level. Further study of microRNAs may lead to novel concepts in the diagnosis and treatment of malignant lymphoproliferative disorders.

    The majority of AIDS-related non-Hodgkin's lymphomas are clinically aggressive monoclonal B-cell Burkitt's lymphomas, large cell lymphomas, or immunoblastic lymphomas. In contrast, the lymphoid proliferations arising in solid organ transplant recipients, collectively referred to as posttransplantation lymphoproliferative disorders (PT-LPDs), represent a clinically and histopathologically heterogeneous group of Epstein-Barr virus (EBV)-driven B-cell proliferations of variable clonal composition. During a retrospective histopathologic review of lymphoid proliferations associated with human immunodeficiency virus (HIV) infection we identified 10 cases that morphologically resemble the polymorphic PT-LPDs. They arose in lymph nodes (five), lungs (two), and the parotid gland, perineum, and skin (one each). They exhibit a diffuse growth pattern and are composed of a polymorphic lymphoid cell population exhibiting a variable degree of plasmacytic differentiation, cytologic atypia, and numbers of atypical immunoblasts. A clonal B-cell population was detected by immunoglobulin heavy and light chain gene rearrangement and/or EBV terminal repeat analysis in 8 of the 10 (80%) cases by Southern blotting. The nongermline hybridizing bands were usually faint, however, suggesting that the clonal B-cell population represented only a subpopulation within the polymorphic lesion. Strong clonal rearrangement bands were present in one case in which there was clear morphologic evidence of transformation to diffuse large cell lymphoma. This case exhibited C-MYC, BCL-6, and p53 gene mutations. One other case exhibited a p53 gene mutation. The remaining eight cases lacked C-MYC, BCL-6, RAS, and p53 gene alterations. Clonal EBV infection was detected in 4 of the 10 (40%) lesions. Like EBV-containing PT-LPDs, all four EBV-positive HIV-associated polymorphic lesions were associated with type A EBV. The Kaposi's sarcoma-associated herpesvirus was detectable in two cases by polymerase chain

    Full Text Available Thymic hyperplasia is usually associated with the treatment of malignant tumours and is sometimes linked with endocrine diseases. For the first time, we report a case of thymic hyperplasia in a patient 2 years after bilateral lung transplantation. Contrast-enhanced chest CT scan was highly suspicious for a posttransplant lymphoma or thymoma. Therefore, the patient received total thymectomy. Excised specimens were sent to the Department of Pathology. Unexpectedly, the histological examination revealed hyperplastic thymic tissue without evidence for a posttransplant lymphoproliferative disorder or malignancy.

    Full Text Available Molecular pathologic testing plays an important role for the diagnosis, prognostication and decision of treatment strategy in lymphoproliferative disease. Here, we briefly review the molecular tests currently used for lymphoproliferative disease and those which will be implicated in clinical practice in the near future. Specifically, this guideline addresses the clonality test for B- and T-cell proliferative lesions, molecular cytogenetic tests for malignant lymphoma, determination of cell-of-origin in diffuse large B-cell lymphoma, and molecular genetic alterations incorporated in the 2016 revision of the World Health Organization classification of lymphoid neoplasms. Finally, a new perspective on the next-generation sequencing for diagnostic, prognostic, and therapeutic purpose in malignant lymphoma will be summarized.

    In view of the widespread use of pesticides in Egypt and the increasing incidence of leukaemia and lymphoma we aimed to assess pesticide exposure and other selected variables as risk factors for lymphoproliferative disorders (leukaemia and non-Hodgkin lymphoma). In a hospital-based, retrospective, case-control study in 2011-2012, adult cases of lymphoproliferative disorders (n = 130) were recruited from outpatient clinics in Menoufia, Egypt, while controls (n = 130) were age- and sex-matched fracture patients. Family history of cancer, exposure to X-rays, smoking and use of hair dyes were not risk factors for lymphoproliferative disorders in univariate analysis. History of exposure to pesticides and HCV infection were significant risk factors for lymphoproliferative disorders in multivariate analysis (OR = 2.24; 95% CI: 1.22-4.11 and OR = 2.67; 95% CI: 1.50-4.80 respectively). The risk was significant for cases of non-Hodgkin lymphoma but not chronic lymphocytic leukaemia.

    Epstein-Barr virus (EBV)-positive mucocutaneous ulcer (EBV MCU) is a B-cell lymphoproliferative disorder occurring in elderly or iatrogenic immunocompromised patients. It has not been reported in solid organ transplant recipients. We observed 7 patients with EBV MCU in a cohort of 70 transplant recipients with EBV posttransplant lymphoproliferative disorder (PTLD). Transplants included: 5 renal, 1 heart, and 1 lung. Median patient age was 61; 5 were male. EBV MCU was observed in oral mucosa in 4 and gastrointestinal tract in 3. Duration of immunosuppressive therapy before EBV MCU was 0.6 to 13 years. Ulcers were undermined by inflammatory cells and polymorphic or monomorphic large cell lymphoproliferation. Reed-Sternberg-like cells were present in 5/7. Large B cells were CD20, CD30, and EBV-encoded RNA positive in all cases. Diagnosis in 3 recent patients was EBV MCU; 4 patients diagnosed before familiarity with EBV MCU were classified as monomorphic large cell (n=3) and polymorphic (n=1) PTLD. None of the patients had EBV DNA in their blood (<1000 copies/mL) at diagnosis or follow-up versus 35/44 transplant patients with systemic PTLD (P<0.001). All lesions resolved with reduced immunosuppression (7/7), change in immunosuppression (2/7), and rituximab (3/7). Five patients are living: 4 healthy, 1 awaiting second renal transplant. Two patients died 3 and 5 years after resolution of EBV MCU. No patient recurred with EBV MCU or other PTLDs. EBV MCU mimics more aggressive categories of PTLD but lacks EBV DNA in blood, which may be a useful distinguishing feature. Lesions are likely to resolve with conservative management. Awareness of EBV MCU in the posttransplant setting is necessary for appropriate diagnosis and treatment.

    The T-cell lymphoproliferative disorders are a heterogeneous group of non-Hodgkin’s lymphomas (NHL) for which current therapeutic strategies are inadequate, as most patients afflicted with these NHL will succumb to disease progression within 2 years of diagnosis. Appreciation of the genetic and immunologic landscape of these aggressive NHL, including PD-L1 (B7-H1, CD274) expression by malignant T cells and within the tumor microenvironment, provides a strong rationale for therapeutic targetin...

    Pretherapy sperm cryopreservation in young men is currently included in good clinical practice guidelines for cancer patients.The aim of this paper is to outline the effects of different oncological treatments on semen quality in patients with testicular neoplasia or lymphoproliferative disorders,based on an 8-year experience of the Cryopreservation Centre of a large public hospital.Two hundred and sixty-one patients with testicular neoplasia and 219 patients with lymphoproliferative disorders who underwent chemotherapy and/or radiotherapy and pretherapy semen cryopreservation were evaluated.Sperm and hormonal parameters (follicle-stimulating hormone (FSH),luteinizing hormone (LH),testosterone,inhibin B levels) were assessed prior to and 6,12,18,24 and 36 months after the end of cancer treatment.At the time of sperm collection,baseline FSH level and sperm concentration were impaired to a greater extent in patients with malignant testicular neoplasias than in patients with lymphoproliferative disorders.Toxic effects on spermatogenesis were still evident at 6 and 12 months after the end of cancer therapies,while an improvement of seminal parameters was observed after 18 months.In conclusion,an overall increase in sperm concentration was recorded about 18 months after the end of cancer treatments in the majority of patients,even if it was not possible to predict the evolution of each single case ‘a priori'.For this reason,pretherapy semen cryopreservation should be considered in all young cancer patients.

    An intralymphatic variant of the cutaneous CD30 lymphoproliferative disorders (cutaneous anaplastic large cell lymphoma [ALCL] and lymphomatoid papulosis [LyP]) has been described recently. We retrieved 60 cases of ALCL of the skin (primary cutaneous: 37; cases with concomitant involvement of 1 regional lymph node: 4; skin involvement from systemic disease: 4; cases with staging results unknown: 15) and 16 cases of LyP, to evaluate the presence of lymphatic vessel involvement by neoplastic cells. A D2-40 immunohistochemical staining was used to highlight lymphatic vessels. Lymphatic vessel involvement was found in 36 cases (60%) of ALCL (primary cutaneous: 24; concomitant: 3; secondary cutaneous: 4; staging unknown: 5), and in 6 cases (37.5%) of LyP. Follow-up data, available in 28 patients with ALCL and 11 with LyP, suggested that lymphatic vessel involvement had no negative prognostic implication. Our study demonstrates that cutaneous CD30 lymphoproliferative disorders are frequently characterized by involvement of the lymphatic vessels. The intralymphatic variant of ALCL and LyP may be explained, at least in part, by a particular lymphotropism of the neoplastic cells of cutaneous CD30 lymphoproliferative disorders.

    Herein we describe the case of a 8-years-old boy with diagnosis of atypical autoimmune lymphoproliferative syndrome (ALPS), carrying heterozygous mutation of CASP10 gene (I406L). He presented with multiple non-invasive infections of the skin, that were associated to chronic non-malignant non-infectious lymphadenopathy, failure to thrive, weakness, arthralgia, relapsing oral aftosis, and expansion of TCRαβ(+) CD4(-)/CD8(-) T cells. This observation suggests that cutaneous infections can be observed in ALPS patients carrying CASP10 mutations.

    Full Text Available Abstract. A role of intracellular proteins of eosinophils and mast cells remains unclear in the patients with hematological neoplasia. There is a substantial evidence that eosinophils possess some common mechanisms of cooperation with mast cells. Therapeutic interventions into key events controlling eosinophil migration may be a leading factor in treatment of hypereosinophylic states in onco-hematological disorders. Due to unknown functions of eosinophils in majority of eosinophilia-associated diseases, it would be useful to establish an algorithm of accurate diagnostics in the patients with eosinophilia, in order to choose more effective treatment in future.We studied serum levels of secretable eosinophil and mast cells proteins in oncohematological patients with increased eosinophil counts. The aim of our study was to test a significance of quantitative assay for tryptase and ECP in the patients with myelo- and lymphoproliferative diseases. The study group included thirty-eight patients with oncohematological diseases, accompanied by a marked eosinophilia (> 0.4 x 109/L. Eighteen patients with bronchial asthma (BA, and eight cases of solid tumors comprised a reference group for polyclonal eosinophilia. The levels of ECP and tryptase were measured in blood serum using a commercial fluoroimmunoenzyme assay («Pharmacia», Uppsala, Sweden. Total ECP levels were markedly increased in general group with hematological malignancies (p < 0.03, , and in cases of chronic GvHD (p < 0.03, and in a sub-group with lymphoproliferative disorders (р = 0.007 as compared to the group of non-hematological diseases.Serum levels of tryptase were significantly increased in the patients with chronic GvHD after allo-HSCT and lymphoproliferative diseases, as compared to the group of patients with solid tumors (р = 0.03, as well in GvHD compared with lymphoproliferative disorders (р < 0.05.A direct correlation was found between serum ECP levels and absolute

    Full Text Available HHV8/EBV-associated germinotropic lymphoproliferative disorder (GLD is a challenging diagnosis given its rarity, the particular clinical presentation, and the lack of expression of markers usually used in establishing hematopoietic lineage. We report a new case of HHV8/EBV GLD in an immunocompetent 78-year-old woman. The diagnosis was made in an incidentally discovered lymphadenopathy. Histological examination showed a nodular lymphoid proliferation centered by aggregates of atypical plasmablastic cells admixed with small lymphoid cells. Tumor cells were strongly positive with EMA, HHV8, LMP1, CD38, CD138, and kappa light chains. They were negative with common lymphoma-associated markers (CD20, CD3, CD15, CD30, CD10, and bcl2. In situ hybridization confirmed the monotypic kappa light chains and the EBV infection (EBER+. A polyclonal pattern of Ig gene rearrangement was detected by PCR analysis. In the adjacent lymph node parenchyma, some germinal centers mimicked Castleman disease. In this case, the differential diagnosis was discussed with an early stage of large B-cell lymphoma arising in HHV8-associated multicentric Castleman disease. The clinical presentation, the immunophenotype, and the molecular results helped to make the accurate diagnosis. Through the review of the nine previously reported cases in literature, we discuss the clinical and pathologic features and the differential diagnosis of HHV8/EBV GLD.

    Hydroa vacciniforme-like lymphoma (HVLL) is an Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disorder of childhood that occurs mainly in Central and South America and Asia. We present the clinicopathological features of 20 Mexican children with HVLL with a median age of 8 years at diagnosis (range, 1-15). All patients presented with skin lesions involving sun-exposed areas, but not exclusively. Fever, lymphadenopathy, and hepatosplenomegaly were often observed. Most patients were treated with immunomodulators and/or immunosuppressive agents, resulting in temporary remission. For 13 patients follow-up was available for a median of 3 years (range, 1 month-13 years). Three patients with long follow-up (9-13 years) are alive with disease. Four patients died, 2 after developing systemic lymphoma. Histologically, the skin showed a predominantly angiocentric and periadnexal Epstein-Barr early RNA+ lymphoid infiltrate with variable atypia and subcutaneous involvement. Fifteen patients showed a T-cell phenotype (12, αβ; 2, γδ; 1, silent phenotype) and monoclonal T-cell receptor-γ rearrangements, whereas 6 exhibited a natural killer (NK)-cell phenotype. Four patients had hypersensitivity to mosquito bites. One patient showed both phenotypes. HVLL is an EBV-associated lymphoproliferative disorder of αβ-, γδ-, or NK-cell phenotype with a broad clinical spectrum, usually prolonged clinical course, and risk for progression to systemic disease.

    Autoimmune Lymphoproliferative Syndrome (ALPS) is a rare inherited disorder of abnormal lymphocyte apoptosis, leading to chronic lymphoproliferation. It presents as lymphadenopathy, hepatosplenomegaly and autoimmune phenomena. Pure red cell aplasia is characterized by normochromic normocytic anemia, reticulocytopenia, and absence of erythroblasts from a normal bone marrow. Only few lymphoproliferative disorders have been associated with erythroid aplasia. The authors are reporting a case of ALPS associated with red cell aplasia in a 7-y-old girl.

The clinical parameters monitored were: B signs were present in 19/41 (43,34%) patients, the superficial or profound adenopathies –were found in 29/41 (70,73%) patients, hepatomegaly – in 38/41 (92,68%) patients, splenomegaly – in 21/41 (51,21%) patients, extra–nodal involvements in 10/41 (24,39%) patients and most frequent in the non–aggressive type of CLD – 6/10 (60%) patients. The hematological and biochemical parameters were: the presence of anemia and thrombocytopenia – found in a small number of patients; lymphocytosis – positive in 33/41 (80,48%) patients, most with HCV infection and non–aggressive type of disease, the presence of autoimmune hemolytic anemia – in 4/41 (9,75%) patients, cryoglobulins – 8/41 (19,51%) patients, all with HCV infection; also the liver function was monitored. Antiviral therapy was administered to 12/41 (29,26%) patients – Lamivudine to 8/41 (19,51%) patients and Ribavirine/Interferon to 4/41 (9,75%) patients. Chemotherapy was given in 32/41 (78%) patients. Monoclonal antibodies anti CD20 (Rituximab) therapy was associated in 6/41 (14,63%) patients. Conclusions. A high incidence in female sex of over 50 years old was noticed. A strong association between B–cell chronic lymphoproliferative disorders and hepatitis viral infection B, C, D was revealed, the most frequent being the C hepatitis virus, associated with the non–aggressive type of CLD, extra–nodal involvement, splenomegaly, lymphocytosis, cryoglobulins, cytolysis and colestasis. The clinical and biological disease history will be monitored during chemotherapy and antiviral treatment. PMID:20945824

    Occult HCV infection is a form of chronic HCV infection characterized by absence of detectable anti-HCV antibodies or plasma HCV-RNA but presence of HCV-RNA in liver biopsy and/or peripheral blood mononuclear cells (PBMCs). The aim of this study was to determine the presence of HCV-RNA in PBMCs of patients with lymphoproliferative disorders. One hundred and four consecutive patients with lymphoproliferative disorders admitted to Firouzgar Hospital from January 2010 to March 2011 were recruited in this cross-sectional study. A 6-ml sample of whole blood was taken from the patients, the total RNA was extracted from the samples after the separation of plasma and PBMCs. The HCV-RNA of the samples was amplified by reverse transcriptase-nested polymerase chain reaction (RT-nested PCR). The HCV genotypes of the positive samples were tested using the INNO-LiPA™ HCV II kit, and the HCV genotypes were then confirmed by sequencing of the 5'-UTR fragments after the PCR products were cloned into a pJET1.2/blunt cloning vector. The mean age of the patients was 48.3 ± 1.76 years (range: 16-83). HCV-RNA was found in PBMCs from 2 (1.9%) of the 104 patients. Genotyping showed that the patients were infected with HCV subtype 1a. One patient suffered non-Hodgkin's lymphoma and the other suffered chronic lymphocytic leukemia. Patients with lymphoproliferative disorders with negative anti-HCV antibodies and negative plasma HCV-RNA may have occult HCV infection. Therefore, in the absence of a liver biopsy, the testing of PBMCs for the detection of genomic HCV-RNA may be beneficial.

    Full Text Available Introduction This study describes the incidence and risk factors of de novo nephrolithiasis among patients with lymphoproliferative or myeloproliferative diseases who have undergone chemotherapy. Materials and Methods From 2001 to 2011, patients with lymphoproliferative or myeloproliferative disorders treated with chemotherapy were retrospectively identified. The incidence of image proven nephrolithiasis after chemotherapy was determined. Demographic and clinical variables were recorded. Patients with a history of nephrolithiasis prior to chemotherapy were excluded. The primary outcome was incidence of nephrolithiasis, and secondary outcomes were risk factors predictive of de novo stone. Comparative statistics were used to compare demographic and disease specific variables for patients who developed de novo stones versus those who did not. Results A total of 1,316 patients were identified and the incidence of de novo nephrolithiasis was 5.5% (72/1316; symptomatic stones 1.8% 24/1316. Among patients with nephrolithiasis, 72.2% had lymphoproliferative disorders, 27.8% had myeloproliferative disorders, and 25% utilized allopurinol. The median urinary pH was 5.5, and the mean serum uric acid, calcium, potassium and phosphorus levels were 7.5, 9.6, 4.3, and 3.8 mg/dL, respectively. In univariate analysis, mean uric acid (p=0.013, calcium (p<0.001, and potassium (p=0.039 levels were higher in stone formers. Diabetes mellitus (p<0.001, hypertension (p=0.003, and hyperlipidemia (p<0.001 were more common in stone formers. In multivariate analysis, diabetes mellitus, hyperuricemia, and hypercalcemia predicted stone. Conclusions We report the incidence of de novo nephrolithiasis in patients who have undergone chemotherapy. Diabetes mellitus, hyperuricemia, and hypercalcemia are patient-specific risk factors that increase the odds of developing an upper tract stone following chemotherapy.

    Pityriasis lichenoides (PL) is a papulosquamous disorder often considered a form of reactive dermatosis and classified with small plaque parapsoriasis (digitate dermatosis). However, some patients with PL have developed large plaque parapsoriasis (LPP) and mycosis fungoides (MF), and lymphoid atypia and T-cell clonality have been reported in lesions of PL. We set out to explore the possibility that PL is a form of T-cell dyscrasia. Cases were selected by natural language search from an outpatient dermatopathology database; 35 cases were reviewed and clinicians and patients were contacted. Hematoxylin and eosin-stained sections were examined and immunophenotyping was carried out on paraffin-embedded, formalin-fixed tissue using antibodies to CD2, CD3, CD4, CD5, CD7, CD8, CD20, CD30, and CD56. In paraffin-embedded tissue, T-cell receptor (TCR)-gamma chain rearrangement was sought through polymerase chain reaction single stranded conformational polymorphism analysis. There were 14 males and 21 females with a mean age of 40 years held clinically to have PL chronica (PLC) (28 cases) and/or PL et varioliformis acuta (PLEVA) (7 cases). Five patients developed large atrophic poikilodermatous and/or annular plaques compatible with MF and/or LPP in a background of typical PLC. All biopsies showed tropism of lymphocytes to an epidermis manifesting psoriasiform hyperplasia, dyskeratosis, parakeratosis, and intraepithelial collections of Langerhans' cells and lymphocytes mimicking Pautrier's microabascesses. Epidermal atrophy, dermal fibroplasia, poikilodermatous alterations, and a dominance of intraepidermal cerebriform cells were seen only in patients with chronic persistent disease (i.e., PLC) and in some cases corresponded with clinical progression to MF. All cases had a T cell-dominant infiltrate, with a CD7 deletion in 21 of 32 biopsies examined; the CD7-negative cells were typically the largest and most atypical forms, often in a cohesive array within the upper layers of

    Background. Occult hepatitis C virus infection (OCI) was identified as a new form of Hepatitis C virus (HCV), characterized by undetectable HCV antibodies and HCV RNA in serum, while HCV RNA is detectable in liver and peripheral blood cells only. Aim. The aim of this study was to investigate the occurrence of OCI in Egyptian patients with lymphoproliferative disorders (LPDs) and to compare its prevalence with that of HCV in those patients. Subjects and Methods. The current study included 100 subjects, 50 of them were newly diagnosed cases having different lymphoproliferative disorders (patients group), and 50 were apparently healthy volunteers (controls group). HCV antibodies were detected by ELISA, HCV RNA was detected in serum and peripheral blood mononuclear cells (PBMCs) by reverse transcription polymerase chain reaction(RT-PCR), and HCV genotype was detected by INNO-LiPA. Results. OCI was detected in 20% of patients group, compared to only 4% OCI in controls group. HCV was detected in 26% of patients group with a slightly higher prevalence. There was a male predominance in both HCV and OCI. All HCV positive patients were genotype 4. Conclusion. Our data revealed occurrence of occult HCV infection in Egyptian LPD patients at a prevalence of 20% compared to 26% of HCV.

    Full Text Available Post-transplant lymphoproliferative disorder (PTLD represents an abnormal lymphoid proliferation that occurs in recipients of solid organ or bone marrow allograft. It includes a diverse group of diseases ranging from polymorphic B-cell hyperplasia to frank malignant lymphoma. Clinical presentation is variable, ranging from asymptomatic to generalized lymphadenopathy, mononucleosis-like syndrome, nodal or extranodal tumors (usually gastrointestinal tract, systemic lymphomatous involvement, and rare (less than 1% of cases fulminant disseminated disease. PTLD is more common in children than in adults. Younger patients usually present with mononucleosis-like symptoms. We present an unusual case of a 5-year old male who developed a widely disseminated leukemic form of PTLD, involving lymph nodes, tonsils, multiple organs, bone marrow, cerebrospinal fluid, and peripheral blood.

    Full Text Available Introduction. Post-transplant lymphoproliferative disorder (PTLD is a heterogeneous group of diseases, characterized by abnormal lymphoid proliferation following transplantation. It is a disease of the immunosuppressed state, and its occurrence is mostly associated with the use of T-cell depleting agents, and also intensification of immunosuppressive regimens. In the majority of cases, PTLD is a consequence of Epstein-Barr virus (EBV infection and is a B-cell hyperplasia with CD-20 positive lymphocytes. The 2008 World Health Organization classification for lymphoid malignancies divides PTLD into four major categories: early lesions, polymorphic PTLD, monomorphic PTLD and Hodgkin PTLD. The treatment and prognosis depend on histology. The cornerstone of PTLD therapy includes reduction/withdrawal of immunosuppression, monoclonal anti CD-20 antibody (rituximab and chemotherapy. Outline of Cases. We reported here our experiences with three patients, two girls aged 7.5 and 15 and a 16-year old boy. They had different organ involvement: brain, combined spleen-liver and intestines, respectively. Even though EBV was a trigger of lymphoid proliferation as it was confirmed by histopathology or in cerebrospinal fluid, qualitative EBV-PCR was positive only in one patient at disease presentation. Reduction of immunosuppression therapy was applied in treatment of all three patients, while two of them received rituximab and ganciclovir. They had an excellent outcome besides many difficulties in diagnosis and management of disease. Conclusion. Qualitative EBV-PCR is not useful marker in pediatric transplant recipients. Our suggestion is that patients with the risk factors like T-cell depleting agents, immunosuppressant protocol or increasing immunosuppressive therapy and EBV miss-match with donor must be more accurately monitored with quantitative EBV PCR.

    Composite tumors are formed when there is intermingling between two components of separate tumors seen histologically. Cases demonstrating composite tubular adenoma with other types of tumors in the colon are rare. Composite tubular adenomas with nonlymphoid tumors including carcinoids, microcarcinoids, and small cell undifferentiated carcinoma have been reported in the literature. The occurrence of composite lymphoma and tubular adenoma within the colorectal tract is extremely rare. Only three cases have been reported and include one case of mantle cell lymphoma and two cases of diffuse large B-cell lymphoma arising in composite tubular adenomas. We present the first case of composite Epstein-Barr virus-associated B-cell lymphoproliferative disorder and tubular adenoma in a rectal polyp with a benign endoscopic appearance.

    We report a rare case of T cell type monomorphic post-transplant lymphoproliferative disorders (PTLD) after autologous stem cell transplantation. A 53-year-old man with multiple myeloma received autologous stem cell transplantation and achieved a very good partial response. Nine months later, he developed a high fever and consciousness disturbance, and had multiple swollen lymph nodes and a high titer of Epstein-Barr (EB) virus DNA in his peripheral blood. Neither CT nor MRI of the brain revealed any abnormalities. Cerebrospinal fluid contained no malignant cells, but the EB virus DNA titer was high. Lymph node biopsy revealed T cell type monomorphic PTLD. Soon after high-dose treatment with methotrexate and cytosine arabinoside, the high fever and consciousness disturbance subsided, and the lymph node swelling and EB virus DNA disappeared. Given the efficacy of chemotherapy in this case, we concluded that the consciousness disturbance had been induced by central nervous system involvement of monomorphic PTLD.

    Full Text Available In this study, data on post-renal transplant lymphoproliferative disorders (PTLD collected from the existing literature were pooled and analyzed to compare the characteristics, predictors and prognosis of small intestinal PTLDs. We performed a comprehensive search for the available data by Pubmed and Google scholar search engines for reports on this subject. Data from 18 previously published studies, comprising 120 renal allograft recipients, were included in the analysis. Renal transplant recipients with intestinal PTLD were significantly less likely to have Hogkin′s and Hogkin′s-like lesions (P = 0.044 and to be younger at the time of transplan-tation (P = 0.07. Except for Hodgkin′s-like lesions, histopathological evaluations elsewhere were comparable between the group with PTLD in the small intestine and age- and sex-matched renal transplant recipients with PTLD in other sites. The overall mortality was relatively higher in the control group (P = 0.09. When death only due to PTLD was used as the outcome, a trend toward better outcome was seen for the intestinal PTLD group compared with the other localizations (P = 0.1. The 1- and 5-year survival rates for intestinal PTLD patients were 57% and 37%, respectively, compared with 54% and 21%, respectively, for the control group. According to our findings based on analysis of international data, renal transplant patients with small intestinal PTLD are more likely to be of younger age but less frequently represent Hodgkin′s and Hodgkin′s-like lesions. They also have better patient survival compared with transplant recipients with PTLD in other locations. Further multi-center prospective studies are needed to confirm our results.

    Epstein-Barr virus (EBV) is involved in the pathogenesis of approximately 40% of lymphoproliferative disorders (LPDs) arising in patients receiving immunosuppressive treatment (IST) for rheumatic diseases, but data from large cohorts are still not available. We aimed to identify clinicopathological features, management and outcome of this condition. We reviewed all published cases of EBV-encoded RNA (EBER)-positive LPDs and included in our analysis one unpublished patient diagnosed in our Hospital. We excluded those cases without an underling rheumatic condition, a specific IST or not reporting univocal data. In the cumulative cohort of 159 patients, most were affected by rheumatoid arthritis (83.0%) and treated with methotrexate (75.4%). 68.5% of LPDs developed between the age of 40 and 70 years, after 13.3±9.6 years from rheumatic disease onset and 58.7±47.0 months of IST. LPDs were mostly B-cell lineage derived (39.0%), Ann Arbor disease's stage I (38.3%) and presented with extra-nodal involvement in 63.1%, which was most frequently represented by central nervous system (17.6%). The most common approach was IST withdrawal (93.3%), variably associated with radiotherapy(RT)/chemotherapy(CT) in 38.3% of cases. Overall, 61.7% of patients achieved a complete remission (CR; 30.2±24.0 months). Among published cases of patients that only suspended IS as first line treatment approach, 67.2% achieved CR. No significant demographic, clinical and histological differences between patients who achieved CR and who did not, and between who achieved CR by IST withdrawal alone and who did not were observed (P>0.05 in all comparison). The current study reviews all the published evidences of EBV-induced LPDs in patients receiving IST treatment for rheumatic conditions. Copyright © 2017 Société française de rhumatologie.

    Post-transplant lymphoproliferative disorders (PTLDs) are aggressive malignancies which represent one of the major post-transplant complications. However, treatment options vary significantly and localized disease may be curatively treated with radiotherapy (RT) or surgery. We report a case of recurrent rectal PTLD, which was successfully treated by chemoimmunotherapy followed by RT. We describe a patient who developed a rectal lymphoproliferative lesion 11 years after kidney transplant, which was successfully treated with consolidative RT using 25.4 Gy sequential to chemoimmunotherapy (R-CHOP). RT was well tolerated and the patient showed no signs of grade 3 or 4 toxicity. This patient is free of recurrence 52 months after RT, with an overall survival of 62 months since diagnosis. Conventionally fractionated moderate-dose RT appears to be a tolerable and effective treatment option for localized PTLD if a sufficient systemic treatment cannot be applied. (orig.) [German] Posttransplantationslymphoproliferative Erkrankungen (PTLDs) sind eine haeufige Komplikation nach einer Organtransplantation.

Wir berichten ueber einen Fall einer rezidivierten rektalen PTLD, die erfolgreich mit einer Chemoimmuntherapie mit anschliessender RT behandelt wurde. Wir beschreiben einen Patienten der 11 Jahre nach einer Nierentransplantation eine PTLD entwickelte. Diese wurde erfolgreich mit konsolidierender RT (25,4 Gy) im Anschluss an eine Chemoimmuntherapie (R-CHOP) behandelt. Die RT wurde komplikationslos vertragen und es zeigten sich keine Nebenwirkungen.

    Monomorphic post-transplant lymphoproliferative disorder commonly resembles diffuse large B-cell lymphoma or Burkitt lymphoma, and most are Epstein-Barr virus (EBV) positive. We retrospectively identified 32 cases of monomorphic post-transplant lymphoproliferative disorder from two institutions and evaluated EBV in situ hybridization; TP53 mutation status; p53, CD30, myc, and BCL2 expression by immunohistochemistry; proliferation index by Ki67; and germinal center vs non-germinal center immunophenotype by Hans criteria. Post-transplant lymphoproliferative disorder arose after hematopoietic stem cell transplant in five and solid organ transplant in 27 patients, a median of 4 and 96 months after transplant, respectively (overall median latency 71 months, range 2-295). The most common morphology was diffuse large B-cell lymphoma (28 cases), with three cases of Burkitt lymphoma, and one case of plasmablastic lymphoma. Ten cases (31%) were EBV negative. Of those with the morphology of diffuse large B-cell lymphoma, the EBV-negative cases were more frequently TP53-mutated (Pnegative (Ppost-transplant lymphoproliferative disorder were older with a longer latency from time of transplant to diagnosis (Ppost-transplant setting and underscores differences between EBV-positive and EBV-negative post-transplant lymphoproliferative disorder in terms of immunophenotype and TP53 mutation frequency, supporting an alternative pathogenesis for EBV-negative post-transplant lymphoproliferative disorder.

    The tumor microenvironment is essential for tumor survival, growth and progression. There are only a few studies on the tumor microenvironment in cutaneous CD30-positive lymphoproliferative disorders. We assessed the composition of the tumor microenvironment using immunohistochemistry studies in skin biopsies from cases diagnosed with lymphomatoid papulosis (LyP: 18 specimens), primary cutaneous anaplastic large-cell lymphoma (PC-ALCL: 8 specimens), and reactive diseases harboring CD30-positive cells (18 specimens). The predominant cells present in LyP and PC-ALCL were CD163+ M2 macrophages (44.7%, 35%), followed by CD8+ tumor infiltrating lymphocytes (11%, 15%), FOXP3+ T-regulatory cells (9%, 4.5%) and programmed cell death 1(PD-1) + lymphocytes (2.2%, 6.8%). In contrast, CD30-positive reactive inflammatory and infectious disorders were characterized by higher numbers of CD123+ plasmacytoid dendritic cells (6.3%) when compared to LyP (1%), and PC-ALCL (1.1%). Key differences exist between the microenvironment of CD30-positive lymphoproliferative disorders and reactive conditions harboring CD30-positive lymphocytes. The high number of tumor associated macrophages, and the close vicinity of these immune cells to the CD30-positive tumor cells might suggest that tumor associated macrophages have direct influence on tumorigenesis in LyP and ALCL. Therefore, modulation of M2 macrophages may represent a new therapeutic strategy in cutaneous CD30-positive lymphoproliferative disorders. © 2016 John Wiley & Sons A/S.

    Posttransplant lymphoproliferative disorder (PTLD) is a major complication of solid-organ transplantation. With human immunodeficiency virus infection (an analogous immunosuppressive state), elevated kappa and lambda immunoglobulin free light chains (FLCs) in peripheral blood are associated with increased risk of lymphoma. To assess the role of B-cell dysfunction in PTLD, we measured circulating FLCs among Canadian transplant recipients, including 29 individuals with PTLD and 57 matched transplant recipients who were PTLD-free. Compared with controls, PTLD cases had higher kappa FLCs (median 1.53 vs. 1.07 times upper limit of normal) and lambda FLCs (1.03 vs. 0.68). Using samples obtained on average 3.5 months before PTLD diagnosis, cases were more likely to have polyclonal FLC elevations (i.e. elevated kappa and/or lambda with normal kappa/lambda ratio: odds ratio [OR] 4.2, 95%CI 1.1-15) or monoclonal elevations (elevated kappa and/or lambda with abnormal ratio: OR 3.0, 95%CI 0.5-18). Strong FLC-PTLD associations were also observed at diagnosis/selection. Among recipients with Epstein-Barr virus (EBV) DNA measured in blood, EBV DNAemia was associated with FLC abnormalities (ORs 6.2 and 3.2 for monoclonal and polyclonal elevations). FLC elevations are common in transplant recipients and associated with heightened PTLD risk. FLCs likely reflect B-cell dysfunction, perhaps related to EBV-driven lymphoproliferation.

    We analyzed the incidence, clinicopathological features, risk factors and prognosis of patients with EBV-associated post-transplant lymphoproliferative disorder (EBV-PTLD) in 288 adults undergoing umbilical cord blood transplantation (UCBT) at a single institution. Twelve patients developed proven EBV-PTLD at a median time of 73 days (range, 36-812). Three-year cumulative incidence (CI) of EBV-PTLD was 4.3% (95% CI: 1.9-6.7). All patients presented with extranodal involvement. Most frequently affected sites were the liver, spleen, central nervous system (CNS), Waldeyer's ring and BM in 7, 6, 4, 3 and 3 patients, respectively. One patient had polymorphic and 11 had monomorphic EBV-PTLD (7 diffuse large B-cell lymphomas not otherwise specified, 4 plasmablastic lymphomas). We confirmed donor origin and EBV infection in all histological samples. EBV-PTLD was the cause of death in 11 patients at a median time of 23 days (range, 1-84). The 3-year CI of EBV-PTLD was 12.9% (95% CI: 3.2-22.5) and 2.6% (95% CI: 0.5-4.7) for patients receiving reduced-intensity conditioning (RIC) and myeloablative conditioning, respectively (P<0.0001). In conclusion, adults with EBV-PTLD after UCBT showed frequent visceral and CNS involvement. The prognosis was poor despite routine viral monitoring and early intervention. An increased risk of EBV-PTLD was noted among recipients of RIC regimens.

    Full Text Available Posttransplant lymphoproliferative disorder (PTLD is a frequent complication of intestinal transplantation and is associated with a poor prognosis. There is currently no consensus on optimal therapy. Recurrent PTLD involving the central nervous system (CNS represents a particularly difficult therapeutic challenge. We report the successful treatment of CNS PTLD in a pediatric patient after liver/small bowel transplantation. Initial immunosuppression (IS was with thymoglobulin, solucortef, tacrolimus, and mycophenolate mofetil. EBV viremia developed 8 weeks posttransplantation, and despite treatment with cytogam and valganciclovir the patient developed a polymorphic, CD20+, EBV+ PTLD with peripheral lymphadenopathy. Following treatment with rituximab, the lymphadenopathy resolved, but a new monomorphic CD20−, EBV+, lambda-restricted, plasmacytoid PTLD mesenteric mass emerged. Complete response of this PTLD was achieved with 6 cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP chemotherapy; however, 4 months off therapy he developed CNS PTLD (monomorphic CD20−, EBV+, lambda-restricted, plasmacytoid PTLD of the brain and spine. IS was discontinued and HD-MTX (2.5–5 gm/m2/dose followed by intrathecal HD-MTX (2 mg/dose ×2-3 days Q 7–10 days per cycle was administered Q 4–7 weeks. After 3 cycles of HD-MTX, the CSF was negative for malignant cells, MRI of head/spine showed near-complete response, and PET/CT was negative. The patient remains in complete remission now for 3.5 years after completion of systemic and intrathecal chemotherapy. Conclusion. HD-MTX is an effective therapy for CNS PTLD and recurrent PTLD that have failed rituximab and CHOP chemotherapy.

    Background Posttransplant lymphoproliferative disorder (PTLD) is a feared complication to organ transplantation, associated with substantial morbidity and inferior survival. Risk factors for PTLD include T cell–depleting induction therapy and primary infection or reactivation of Epstein-Barr virus. Possible associations between certain HLA types and the risk of developing PTLD have been reported by other investigators; however, results are conflicting. Methods We conducted a retrospective, population-based study on 4295 Danish solid organ transplant patients from the Scandiatransplant database. Having identified 93 PTLD patients in the cohort, we investigated the association of HLA types with PTLD, Epstein-Barr virus status and time to PTLD onset. The outcomes survival and PTLD were evaluated using Cox regression; mismatching, and the PTLD-specific mortality were evaluated in a competing risk analysis. Results Risk of PTLD was associated with male sex (odds ratio, 1.70; 95% confidence interval, 1.07-2.71), and, in women, HLA-DR13 conferred an increased risk (odds ratio, 3.22; 95% confidence interval, 1.41-7.31). In multivariate analysis, HLA-B45 and HLA-DR13 remained independent predictive factors of PTLD. Mismatching in the B locus was associated with a reduced risk of PTLD (P < 0.001). Overall survival was poor after a PTLD diagnosis and was significantly worse than that in the remaining transplant cohort (P < 0.001). Conclusions Our data indicate risk-modifying HLA associations, which can be clinically useful after transplantation in personalized monitoring schemes. Given the strong linkage disequilibrium in the HLA region, the associations must be interpreted carefully. The large size, virtually complete ascertainment of cases and no loss to follow-up remain important strengths of the study. PMID:27500227

  7. Post-transplant lymphoproliferative disorders: implications for acquired immunodeficiency syndrome-associated malignancies.

    Science.gov (United States)

    Swinnen, L J

    2001-01-01

    Post-transplant lymphoproliferative disorders (PTLDs) comprise a histologic spectrum, ranging from hyperplastic-appearing lesions to frank non-Hodgkin's lymphoma or multiple myeloma histology. Multiple clones may coexist, each representing a discrete lymphomagenic event, a situation that is unique to immunodeficiency states. The incidence varies from 1% in renal recipients to 5% in heart recipients, but can be markedly increased by the use of anti-T-cell therapies or by T-cell depletion in bone marrow transplantation. PTLD continues to arise, even many years after transplantation, and late T-cell lymphomas have recently been recognized. Pretransplant Epstein-Barr virus (EBV) seronegativity increases risk to as high as 30%-50%. PTLD has a highly variable clinical picture; certain patterns are, however, seen. Reversibility of PTLD with reduction in immunosuppressives has long been recognized. Predicting reversibility has been difficult. The presence or absence of bcl-6 mutations has recently been identified as being of predictive value. Surgical resection can be curative. Cytotoxics, although problematic, can also be curative. Long-term remission has been achieved with anti CD21 and CD24 antibodies; efficacy has been reported for interferon alfa and for rituximab. In vitro expanded EBV-specific T cells have been effective as treatment and as prophylaxis in the setting of bone marrow transplantation. EBV viral load measured in blood appears to associate with the emergence of PTLD and may facilitate prophylactic studies. PTLD is a model of immunodeficiency-related EBV lymphomagenesis. Pathogenetic, therapeutic, and prophylactic insights gained from the study of PTLD are likely to be applicable to the acquired immunodeficiency syndrome setting.

    Intravenous immunoglobulin replacement therapy represents the standard treatment for hypogammaglobulinemia secondary to B-cell lymphoproliferative disorders. Subcutaneous immunoglobulin infusion is an effective, safe and well-tolerated treatment approach in primary immunodeficiencies but no extensive data are available on their use in secondary hypogammaglobulinemia, a frequent phenomenon occurring after treatment with anti-CD20 monoclonal antibodies in lymphoproliferative disorders. In this retrospective study we evaluated efficacy (serum IgG trough levels, incidence of infections per year, need for antibiotics) and safety (number of adverse events) of intravenous (300 mg/kg/4 weeks) versus subcutaneous (75 mg/kg/week) immunoglobulin replacement therapy in 61 patients. In addition, the impact of the infusion methods on quality of life was compared. All patients were treated with subcutaneous immunoglobulin, and 33 out of them had been previously treated with intravenous immunoglobulin. Both treatments appeared to be effective in replacing Ig production deficiency and in reducing the incidence of infectious events and the need for antibiotics. Subcutaneous immunoglobulin obtained a superior benefit when compared to intravenous immunoglobulin achieving higher IgG trough levels, lower incidence of overall infection and need for antibiotics. The incidence of serious bacterial infections was similar with both infusion ways. As expected, a lower number of adverse events was registered with subcutaneous immunoglobulin, compared to intravenous immunoglobulin, with no serious adverse events. Finally, we observed an improvement in health-related quality of life parameters after the switch to subcutaneous immunoglobulin. Our results suggest that subcutaneous immunoglobulin is safe and effective in patients with hypogammaglobulinemia associated to lymphoproliferative disorders.

    Full Text Available Epstein-Barr virus (EBV, the causative agent of infectious mononucleosis, plays a significant role as a cofactor in the process of tumorigenesis, and has consistently been associated with a variety of malignancies especially in immunocompromised patients. Forty-four children and adolescents (21 liver transplant patients, 7 heart transplant, 5 AIDS, 3 autoimmune hepatitis, 2 nephritic syndromes, 2 medullar aplasia, 2 primary immunodeficiency disorder patients, 1 thrombocytopenic purpura and 1 systemic lupus erythematosus presenting with chronic active EBV infection (VCA-IgM persistently positive; VCA-IgG > 20 AU/mL and positive IgG _ EBNA had peripheral blood samples obtained during clinically characterized EBV reactivation episodes. DNA samples were amplified in order to detect and type EBV on the basis of the EBNA-2 sequence (EBNA2 protein is essential for EBV-driven immortalization of B lymphocytes. Although we have found a predominance of type 1 EBNA-2 virus (33/44; 75%, 10 patients (22.73% carried type 2 EBNA-2, and one liver transplant patient (2.27% a mixture of the two types, the higher proportion of type 2 EBV, as well as the finding of one patient bearing the two types is in agreement with other reports held on lymphoproliferative disorder (LPD patients, which analyzed tumor biopsies. We conclude that EBNA-2 detection and typing can be performed in peripheral blood samples, and the high prevalence of type 2 in our casuistic indicates that this population is actually at risk of developing LPD, and should be monitored.

  10. SV40 and p53 as team players in childhood lymphoproliferative disorders.

    2011-05-01

    Simian virus 40 (SV40) is known to be potently oncogenic and can induce several types of tumours, such as lymphoma. p53 was discovered as a cellular partner of the SV40 large T-antigen, the oncoprotein of this virus. There have not been many studies on SV40 and p53 in lymphomas and the ones that exist, are controversial. A comparison of these two components in lymphoma has not been reported previously. We examined 91 lymphomas [60 B-cell non-Hodgkin's lymphomas (B-NHLs), 19 B-cell acute lymphoblastic leukemias (B-ALLs), 7 B-cell precursor acute lymphoblastic leukemias and 5 T-cell acute lymphoblastic leukemias] for the presence of SV40. Overall, 40 samples from 12 B-NHL/19 B-ALL patients were additionally investigated for p53 mutation in the hot-spot exons 5 to 8. Overall, we found 62/91 lymphomas to be SV40-positive, among them 16/19 B-ALLs and 38/60 B-NHLs. SV40 was absent in 147 of the 149 blood control samples. We found 11 p53 mutations in 19 B-ALL patients: 5 in exon 5 (codons 132, 141, 143, 155 and 181), 4 in exon 7 (codons 236, 238 and 248), 2 in exon 8 (codon 273). In B-NHL patients we found p53-mutations in 9/12 samples: 6 of these in 3 lymph nodes (LNs). One LN harboured 3 different p53 mutations: Exon 5 (codon 132), exon 6 (codon 213) and exon 8 (codon 288). Another LN showed 2 different p53 mutations: Exon 6 (codon 213) and exon 8 (codon 285). Except for 1 nonsense mutation in an LN of a B-NHL patient, all 20 mutations were missense mutations, 2 were homozygous, both found in B-NHL-samples, and one of these (codon 175) is known to cause the global denaturation of p53. All occur in the DNA-binding domain of p53. All specimens showing a p53 mutation, were SV40-positive. p53 mutaions found in LNs of B-NHL patients harbour high SV40 copy numbers. Our data strongly support an important role for SV40, as well as a strong association of SV40 and p53 in childhood lympho-proliferative disorders.

    Background After acute infection of Epstein-Barr virus, Epstein-Barr virus-infected B cells survive but usually do not show clonal proliferation. However, Epstein-Barr virus-infected B cells occasionally acquire a proliferative capacity that provokes clonal lymphoproliferative disorders. We herein present a case with Epstein-Barr virus-infected CD30+ B cell and immunoglobulin G4+ plasmacytoid cell proliferation in the lymph nodes, suggesting a pathological and clinical interaction between Eps...

    The objective of the study was to evaluate the feasibility of a UK-based real-time service to improve the diagnosis and management of lymphoproliferative disorders (LPDs) in Ghana. Adult patients reporting to hospital with a suspected LPD, during a 1 year period, were prospectively enrolled. Bone marrow and/or lymph node biopsies were posted to the Haematology Malignancy Diagnostic Service (HMDS), Leeds, UK and underwent morphological analysis and immunophenotyping. Results were returned by e-mail. The initial diagnoses made in Ghana were compared with the final HMDS diagnoses to assess the contribution of the HMDS diagnosis to management decisions. The study was conducted at the two teaching hospitals in Ghana-Komfo Anokye, Kumasi and Korle Bu, Accra. Participants comprised 150 adult patients (>/=12 years old), 79 women, median age 46 years. Bone marrow and lymph node biopsy samples from all adults presenting with features suggestive of a LPD, at the two teaching hospitals in Ghana, over 1 year were posted to a UK LPD diagnostic centre, where immunophenotyping was performed by immunohistochemistry. Molecular analysis was performed where indicated. Diagnostic classifications were made according to international criteria. Final diagnosis was compared to the initial Ghanaian diagnosis to evaluate discrepancies; implications for alterations in treatment decisions were evaluated. Median time between taking samples and receiving e-mail results in Ghana was 15 days. Concordance between initial and final diagnoses was 32% (48 of 150). The HMDS diagnosis would have changed management in 31% (46 of 150) of patients. It is feasible to provide a UK-based service for LPD diagnosis in Africa using postal services and e-mail. This study confirmed findings from wealthy countries that a specialised haematopathology service can improve LPD diagnosis. This model of Ghana-UK collaboration provides a platform on which to build local capacity to operate an international quality

    Full Text Available Post-transplantation lymphoproliferative disorders (PTLD localized to the central nervous system (CNS is a rare but potentially fatal side-effect of immunosuppression for organ transplantation. Till now, to the best of our knowledge, the total number of such cases reported worldwide is less than 100. In this survey, we collected the data of PTLD localized to the CNS (CNS-PTLD and compared this data with other PTLD patients with localizations to other areas serving as the control group. A comprehensive search was performed for studies reporting CNS-PTLD data in the Pubmed and Google scholar search engines. Finally, international data from 21 different studies were included in the analysis. Overall, 367 patients were entered into analysis. Organ recipients with CNS-PTLD had comparable gender make up, lymphoma cell types, Epstein-Barr virus infection rate, remission and mortality rates, with PTLD patients having other localizations. Multiorgan involvement as well as disseminated lymphoma were significantly more prevalent in the control group (P <0.05. At the last follow-up, 192 (60% patients were dead (47 missing data. Irrespective of whether the overall death or only death due to PTLD was used as the final outcome, we found that the survival rates were similar for patients of the two groups (P = 0.895. Renal transplant recipients are at greater risk for developing CNS involvement by PTLD, while heart and liver recipients represent significant lower risks for the same. This study showed that PTLD patients who had CNS presentation have quite a comparable outcome compared with those with other areas of localization. However, further prospective studies are needed for reaffirming our findings.

    Posttransplantation lymphoproliferative disorder (PTLD) is a serious complication of organ transplantation, with an incidence of 0.8% to 20% in heart transplant (HTx) recipients, and standard treatment may be too toxic in some cases. Rituximab is an anti-CD20 monoclonal antibody that has demonstrated efficacy in patients with various lymphoid malignancies and has been demonstrated effective in combination with chemotherapy regimens such as CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone). Cardiotoxicity with CHOP remains a major concern for treating HTx recipients with PTLD, however. We present a case of an HTx recipient with sick sinus syndrome and PTLD who was successfully treated with rituximab alone, avoiding the cardiotoxicity of CHOP. The cardiotoxicity induced by CHOP should be kept in mind in HTx recipients with PTLD, especially when there is an existing heart problem in such recipients. Monotherapy with rituximab can be considered a safe choice.

    We report a 48-year-old female who developed lymphoproliferative disorder (LPD) during treatment of rheumatoid arthritis (RA) with methotrexate (MTX). She presented with multiple tumors in the cervical lymph nodes (LNs), multiple lung shadows and round shadows in both kidneys with pancytopenia and a high CRP level. The LN showed CD8-positive T-cell LPD associated with Epstein-Barr (EB) virus-infected B-cells. Clonality assays for immunoglobulin (Ig) heavy chain and T-cell receptor gamma (TCRγ) were negative. The cessation of MTX without chemotherapy resulted in the complete disappearance of the tumors and abnormal clinical features. We compared this case with previously published ones and discuss the pathological findings, presuming that the proliferation of CD8 T-cells was a reactive manifestation to reactivated EB virus-infected B-cells.

    An 84-year-old woman was referred to our hospital presenting anemia. Her hemoglobin level was 5.8 g/dL, and white blood cell count was 9400/μL, consisting of 82% lymphocytes. Given the lymphocyte phenotype (CD2+, CD3-, CD16+, and CD56-) and negative whole blood EBV viral load, we made a diagnosis of chronic lymphoproliferative disorder of NK cells (CLPD-NK). We suspected hemolytic anemia because of the high levels of reticulocytes in the peripheral blood and the low haptoglobin value. Although the direct Coombs test was negative and there was no cold agglutination, we examined her red-blood-cell-bound IgG (RBC-IgG), which was elevated. She was diagnosed as having as Coombs-negative autoimmune hemolytic anemia (AIHA). We report the effectiveness of oral cyclophosphamide for Coombs-negative autoimmune hemolytic anemia in CLPD-NK.

    X-linked lymphoproliferative disease (XLP) and IL-2-inducible T cell kinase (ITK) deficiency are rare immunodeficiencies with a spectrum of clinical manifestations. Although there are no official guidelines for allogeneic hematopoietic stem cell transplantation (HSCT) in these patients, previous reports have shown that reduced intensity conditioning regimens provide successful engraftment with limited toxicity. Here, we report on three children with XLP and one with ITK deficiency, who underwent successful HSCT using a rituximab containing conditioning regimen, and review the current literature.

    IgG4-related disease is a novel lymphoproliferative disorder that shows hyper-IgG4-γ-globulinemia and IgG4-producing plasma cell expansion in affected organs with fibrotic or sclerotic changes. Patients show systemic inflammatory conditions and various symptoms depending on the affected organ. Since the first report of patients with elevated serum IgG4 in sclerosing pancreatitis in 2001, various systemic disorders described by many names have been reported. Despite similarities in the organs involved in IgG4-related Mikulicz's disease and Sjögren's syndrome, there are marked clinical and pathological differences between these conditions. Most patients diagnosed with autoimmune pancreatitis in Japan have IgG4-related pancreatitis [Type 1 autoimmune pancreatitis (AIP), lymphoplasmacytic sclerosing pancreatitis (LPSP)], a disease distinct from some of the western type [Type 2 AIP, idiopathic duct-centric chronic pancreatitis (IDCP), autoimmune pancreatitis with granulocytic epithelial lesions (GEL)]. Diagnosis of IgG4-related disease is characterized by both elevated serum IgG4 (>135 mg/dL) and histopathological features including lymphocyte and IgG4(+) plasma cell infiltration (IgG4(+) plasma cells/IgG(+) plasma cells>40%). Differential diagnosis from other distinct disorders, such as sarcoidosis, Castleman's disease, Wegener's granulomatosis, lymphoma, cancer, and other existing conditions associated with high serum IgG4 level or abundant IgG4-bearing plasma cells in tissues is necessary. We have begun a clinical prospective study to establish a treatment strategy (Phase II prospective treatment study for IgG4-multiorgan lymphoproliferative syndrome: UMIN R000002311).

    A case of primary mucosal CD30-positive T-cell lymphoproliferative disorder of the head and neck rarely involving epiglottis in a 59-year-old male was reported. Histologically, the ulcerative mucosa was affected by sheets of mixed inflammatory infiltration, with scattered large atypical lymphoid cells arranging in an individual or small clusters with focal epidermotropism. Immunohistochemically, tumor cells were uniformly immunoreactive to antibodies against CD2, CD3, CD7, CD43, CD4, TIA-1, with a heterogeneous expression of CD30, but negative for CD20, CD79a, CD21, CD8, CD56, ALK, EMA, granzyme B. Epstein-Barr virus encoded RNA (EBER) were detected. Genetically, T-cell receptor (TCR) γ gene showed an oligoclonal rearrangement. This first case developing in epiglottis demonstrates mucosal CD30-positive T-cell lymphoproliferative disorders are characteristic of a broad clinicopathologic spectrum similar to the counterpart in the skin with a favorable prognosis.

    Rearrangements are developmentally regulated genetic recombinations in T and B cells which generate functional T cell receptor (TcR) and immunoglobulin genes, respectively. Different variable, sometimes diversity, and joining gene segments which are discontinuously spread out within their chromosomal location in germline configuration, are randomly assembled in individual lymphocytes. These rearrangements can be detected by Southern Blot analysis if more than 5% of a total lymphocyte population in a biopsy specimen carries the same clonal rearrangement. We analyzed DNA from 324 snap-frozen biopsy specimens from lympho-proliferative disorders. None of the 20 reactive lesions and four malignant myelomonocytic tumors had a clonal antigen receptor gene rearrangement. All 117 malignant B cell lymphomas of different subtypes and 95 of 97 malignant T cell lymphomas showed a clonal gene rearrangement. Only two angioimmunoblastic lymphadenopathy(AILD)-type T cell lymphomas did not have immune receptor gene rearrangements. They were morphologically indistinguishable from the other 47 T/AILD lymphomas with clonal rearrangement patterns. In most cases TcR beta and immunoglobulin heavy chain (IgH) gene probes were sufficient for lineage assignment of the clonal T or B lymphocyte population. In 18% of B lymphomas, however, a cross-lineage rearrangement of TcR beta genes, and in 20% of the T cell lymphomas a clonal IgH gene rearrangement was detected. After exclusion of centrocytic, large cell anaplastic lymphomas (LCAL) of B-type, and T/AILD lymphomas which are overrepresented in our study, only 10% of the remaining 147 T and B cell lymphomas had aberrant rearrangements. TcR rearrangements other than those of the beta chain genes were extremely rare in B cell lymphomas, as were Ig kappa rearrangements in T lymphomas. Only two T/AILD lymphomas had IgH and Ig kappa rearrangement in addition to their clonal T cell receptor gene rearrangements. Both samples likely contain a clonal B

    Currently, the lack of a universal and specific marker of clonality hampers the diagnosis and classification of chronic expansions of natural killer (NK) cells. Here we investigated the utility of flow cytometric detection of aberrant/altered NK-cell phenotypes as a surrogate marker for clonality, in the diagnostic work-up of chronic lymphoproliferative disorders of NK cells (CLPD-NK). For this purpose, a large panel of markers was evaluated by multiparametric flow cytometry on peripheral blood (PB) CD56(low) NK cells from 60 patients, including 23 subjects with predefined clonal (n = 9) and polyclonal (n = 14) CD56(low) NK-cell expansions, and 37 with CLPD-NK of undetermined clonality; also, PB samples from 10 healthy adults were included. Clonality was established using the human androgen receptor (HUMARA) assay. Clonal NK cells were found to show decreased expression of CD7, CD11b and CD38, and higher CD2, CD94 and HLADR levels vs. normal NK cells, together with a restricted repertoire of expression of the CD158a, CD158b and CD161 killer-associated receptors. In turn, NK cells from both clonal and polyclonal CLPD-NK showed similar/overlapping phenotypic profiles, except for high and more homogeneous expression of CD94 and HLADR, which was restricted to clonal CLPD-NK. We conclude that the CD94(hi)/HLADR+ phenotypic profile proved to be a useful surrogate marker for NK-cell clonality.

    Posttransplant patients are at risk of developing a potentially life-threatening posttransplantation lymphoproliferative disorder (PTLD), most often of diffuse large B cell lymphoma (DLBCL) morphology and associated with Epstein-Barr Virus (EBV) infection. The aim of this study was to characterize the clinicopathological and molecular-genetic characteristics of posttransplant DLBCL and to elucidate whether EBV(+) and EBV(-) posttransplant DLBCL are biologically different. We performed gene expression profiling studies on 48 DLBCL of which 33 arose posttransplantation (PT-DLBCL; 72% EBV+) and 15 in immunocompetent hosts (IC-DLBCL; none EBV+). Unsupervised hierarchical analysis showed clustering of samples related to EBV-status rather than immune status. Except for decreased T cell signaling these cases were inseparable from EBV(-) IC-DLBCL. In contrast, a viral response signature clearly segregated EBV(+) PT-DLBCL from EBV(-) PT-DLBCL and IC-DLBCL cases that were intermixed. The broad EBV latency profile (LMP1+/EBNA2+) was expressed in 59% of EBV(+) PT-DLBCL and associated with a more elaborate inflammatory response compared to intermediate latency (LMP1+/EBNA2-). Inference analysis revealed a role for innate and tolerogenic immune responses (including VSIG4 and IDO1) in EBV(+) PT-DLBCL. In conclusion we can state that the EBV signature is the most determining factor in the pathogenesis of EBV(+) PT-DLBCL.

    BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is a potential complication of solid organ or bone marrow transplants. The main PTLD risk factors are: the Epstein-Barr virus (EBV), transplant type, and use of immunosuppressants. It mainly consists of an uncontrolled growth of lymphocytes in transplant recipients under chronic immunosuppressive therapy. About 85% of PTLDs are EBV-containing B-cell proliferations; 14% are T-cell proliferations, of which only 40% contain EBV; and the remaining 1% is NK-cell or plasmocyte proliferations. PTLD may present various clinical manifestations, from non-specific mononucleosis-like syndrome to graft or other organ damage resulting from pathologic lymphocyte infiltration. PTLD may manifest in the oral cavity. CASE REPORT The objective of this study was to present the case of a 13-year-old female living-donor liver transplant recipient, resulting from biliary cirrhosis caused by congenital biliary atresia, with exophytic fibrous lesions on buccal mucosa and tongue. Exophytic and hyperplastic lesion of oral mucosa were removed and histopathological examination revealed polymorphic PTLD. The patient underwent 6 cycles of CHOP chemotherapy and all the oral lesions regressed completely. CONCLUSIONS All oral pathological lesions in organ transplant recipients need to be surgically removed and histopathologically examined because they present an increased risk of neoplastic transformations such as PTLD.

    T-cell receptor gene rearrangement analysis is a useful technique to detect clonality and determine lineage of lymphoid neoplasms. We examined 103 patients with mycosis fungoides, Sézary syndrome, peripheral T cell lymphoma, potentially malignant lymphoproliferative disorders including pre-Sézary syndrome, large plaque parapsoriasis, lymphomatoid papulosis and follicular mucinosis, and various benign inflammatory infiltrates. A clonal rearrangement was detected in skin samples in 20 of 24 patients with mycosis fungoides and in peripheral blood samples in 19 of 21 patients with Sézary syndrome. A clonal population was also detected in seven of eight cases classified as peripheral T cell lymphoma. The potentially malignant dermatoses tended to have clonal rearrangement, with the exception of large plaque parapsoriasis, and further follow-up is needed to correlate clonality with the disease course. These studies demonstrate the value of molecular genetics as an adjunct to morphology in the examination of patients with cutaneous lymphoproliferative disease.

    Chronic hepatitis C (CHC) has been associated with lymphoproliferative disorders (LPD) such as mixed cryoglobulinemia syndrome (MCS), monoclonal gammopathy of undetermined significance (MGUS), and B-cell non-Hodgkin lymphoma (B-NHL). The aim of the present study is to assess MCS, MGUS, and B-NHL prevalence in a cohort of CHC-infected patients and to evaluate the association of demographic, clinical, and virologic factors with the presence of LPDs. A total of 121 CHC patients with LPDs (50 M, 71 F; mean age 61.5 ± 11.8) and 130 CHC patients without extrahepatic manifestations (60 M, 70 F; mean age 60.4 ± 9.2) were retrospectively enrolled from a cohort of 1313 CHC patients between January 2006 and December 2013. Patients with LPDs included: 25 patients with MCS (9 M, 16 F; mean age 60.2 ± 1.4), 55 patients with MGUS (18 M, 37 F; mean age 61.3 ± 12.1), and 41 patients with B-NHL (23 M, 18F; mean age 62.5 ± 11.0) RESULTS: Patients with MCS (25/1313; 1.9%), MGUS (55/1313; 4.2%), and B-LNH (41/1313; 3.1%) did not differ in age, severity of liver disease, HCV genotype, and response to antiviral therapy. Using multivariate logistic regression analysis, a positive association was found between the presence of cirrhosis and MGUS (odds ratio [OR] = 2.8924, 95% confidence interval [CI] 1.2693-6.5909; P = 0.012) and between cirrhosis and B-NHL (OR = 3.9407, 95% CI 1.7226-9.0153; P = 0.001), whereas no association with MCS diagnosis emerged. Despite the pathogenetic mechanism of HCV-associated LPDs is still unclear, cirrhosis is an additional risk factor for the development of lymphoproliferative disorders in patients with chronic HCV infection. © 2014 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Full Text Available The incidence of post-transplantation lymphoproliferative disorder (PTLD in the adult renal transplant population ranges from 0.7% to 4%. The majority of cases involve a single site and arise, on average, seven months after transplantation. Histopathology usually reveals B-cell proliferative disease and has been standardized into its own classification. Treatment modalities consist of decreased immunosuppression, eradication of Epstein-Barr virus, surgical resection, systemic chemotherapy and monoclonal antibody therapy; however, mortality remains high, typically with a short survival time. In patients who have undergone renal transplantation, approximately 10% of those with PTLDs present with gastrointestinal symptomatology and disease. Reported sites include the stomach, and small and large bowel. Very few cases of Helicobacter pylori or mucosal-associated lymphoid tissue have been described in association with PTLD. In the era of cyclosporine immunosuppression, the incidence of PTLD affecting the gastrointestinal tract may be increasing in comparison with the incidence seen with the use of older immunosuppression regimens. A case of antral PTLD and H pylori infection occurring three months after renal transplantation is presented, and the natural history and management of gastric PTLD are reviewed.

    It is well established that Down's syndrome exhibits a predisposition to development of leukemia, however, association between aplastic anemia and Down's syndrome is exceptional. Herein, we describe a case of aplastic anemia occurring in Down's syndrome following post-transplant lymphoproliferative disorder (PTLD) after bone marrow transplantation (BMT). A 27-year-old Japanese male with Down's syndrome presented with a headache. Laboratory tests revealed severe pancytopenia, and bone marrow biopsy demonstrated hypocellular bone marrow with decrease of trilineage cells, which led to a diagnosis of aplastic anemia. One year after diagnosis, he was incidentally found to have an anterior mediastinal tumor, which was histopathologically diagnosed as seminoma. Subsequently, he received BMT from a female donor, and engraftment was observed. Three months after transplantation, he experienced cough and high fever. Biopsy specimen from the lung revealed diffuse proliferation of large-sized lymphoid cells expressing CD20 and EBER. These lymphoid cells had XY chromosomes. Thus, a diagnosis of EBV-associated PTLD was made. This is the seventh documented case of aplastic anemia occurring in Down's syndrome. Association between aplastic anemia and Down's syndrome has not been established, therefore, additional clinicopathological studies are needed. Moreover, this is the first case to undergo BMT for aplastic anemia in Down's syndrome. Although engraftment was observed, he developed EBV-positive PTLD. The neoplastic cells of the present case were considered to be of recipient origin, although the majority of PTLD cases with BMT are of donor origin.

    Full Text Available We report an unusual case of a localized Epstein-Barr virus (EBV-positive B cell lymphoproliferative disorder (LPD/polymorphous B cell lymphoma of the urinary bladder in a 67 years old female patient. She had no known predisposing immunodeficiencies and presented with recent onset of hematuria. The CT and cystoscopic examination revealed a localized 2.5 cm polypoid or plaque-like mucosal mass on the right posterior and lateral wall of the bladder. The biopsy sample showed a diffuse and densely polymorphous atypical lymphoid infiltrate admixed with numerous small lymphocytes, histiocytes and occasional plasma cells and neutrophils. The large atypical cells were CD20+, CD79a+, CD30+, CD43+ and they were strongly positive for EBV by in situ hybridization using anti-EBER-1 probe. Polymerase chain reaction (PCR for immunoglobulin heavy chain gene rearrangement study showed a clonal gene rearrangement. The findings indicated EBV+LPD of the bladder. Primary lymphoma of bladder is rare and primary EBV+LPD of the bladder has not been previously described. Potential misdiagnosis of poorly differentiated urothelial carcinoma can occur and accurate diagnosis depends on comprehensive immunohistochemical and molecular workups.

    T-cell or natural killer (NK)-cell posttransplant lymphoproliferative disorder (T-PTLD) is a rare but severe complication after transplant. Here we present the clinicopathological features of a single-center series of nine cases. Additionally, we summarize the clinicopathological findings of 147 cases of T/NK-cell PTLD reported in the literature in an attempt to define subtype-specific characteristics. T/NK-cell PTLD occurs in patients of all ages, usually extranodally, and most frequently after kidney transplant. Organ specific incidence, however, is highest following heart transplant. Approximately one-third of T-cell PTLDs are Epstein-Barr virus (EBV)-related, with peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) being the most prevalent EBV-associated T-cell PTLD. A male predominance is observed, which is most striking in the EBV(+) group, particularly in PTCL, NOS. With a median posttransplant interval of 72 months, T-cell PTLDs are among the late-occurring PTLDs. Of the most common T-cell PTLDs, anaplastic large cell lymphoma (ALCL) has the best prognosis, whereas PTCL, NOS and hepatosplenic T-cell lymphoma (HSTCL) have the worst prognosis. EBV(+) cases seem to have a longer survival than EBV(-) cases, suggesting a different pathogenetic mechanism.

    To investigate the chest computed tomography (CT) and F-18 fluoro-2-deoxy-D-glucose positron emission tomographic (FDG-PET) findings of posttransplant lymphoproliferative disorder (PTLD) in the thorax.From November 2004 to February 2013, the cases of 12 adult patients (3 female and 9 male, age range 34-68, and median age 46 years) with proven PTLD were retrospectively reviewed. The transplanted organs included the kidney (5/12), liver (4/12), heart (1/12), combined kidney and pancreas (1/12), and hematopoietic stem cell (1/12). We investigated the relationship of the Epstein-Barr virus (EBV) to the patients' long-term follow-up, and evaluated the characteristics of the lesions on the chest CT and FDG-PET. The lesions were classified into 2 patterns: that of lymph node and lung involvement.The interval between the transplantation and the onset of PTLD was 2 to 128 months (median, 49). Positive EBV-encoded RNA in the pathologic specimens was found in 10 patients (83.3%). Eight patients were positive for EBV PCR in their blood, and 3 patients showed seroconversion without antiviral therapy. The responses to treatment were complete in 7 cases (58.3%), partial remission in 4 cases (33.3%), and undetermined in 1 case (8.3%). The more common chest CT patterns showed lymph node involvement (10/12) rather than lung involvement (3/12). The median maximum-standardized uptake value on the FDG-PET scans was 7.7 (range, 2.7-25.5).In patients with PTLD involving the thorax, lymphadenopathy was the more common manifestation on the chest CT rather than lung involvement. The lesions showed hypermetabolism on FDG-PET.

    Post-transplant lymphoproliferative disorder (PTLD) is a well-known complication following prolonged immunosuppression. Contrary to other lymphomas, there is no standardized imaging approach to assess PTLD either at staging or for response to therapy. Positron emission tomography/computed tomography (PET/CT) is an imaging modality that has proven to be useful in lymphoma. However, there is still limited data concerning its use in pediatric PTLD. Our study evaluates the use of PET/CT in pediatric PTLD at our institution. To assess the role of PET/CT in pediatric PTLD, we reviewed the pediatric patients with PTLD who had undergone PET/CT at our institution between 2000 and 2016. Nine patients were identified. Six had PET/CT at diagnosis. All lesions seen on CT were identified with PET/CT. Fourteen PET/CTs were done during treatment. Eight PET/CTs were negative, including three where CT showed areas of uncertain significance. In these cases, PET/CT helped us to stop treatment and the patients remain in remission after a long follow-up (mean 74.3 months; range 12.4-180.9 months). PET/CT revealed additional disease in two cases, therefore treatment was intensified. Six biopsies and close follow-up was done to confirm PET/CT results. In one case, PET/CT did not identify central nervous system involvement demonstrated on magnetic resonance imaging. PET/CT may have an important role in the staging and follow-up of pediatric PTLD. In our cohort, PET/CT was helpful in staging and assessing treatment response and in clarifying equivocal findings on other imaging modalities. © 2017 Wiley Periodicals, Inc.

    Full Text Available Post-transplant lymphoproliferative disorders (PTLD are a life-threatening complication of solid organ transplantation or, more rarely, hematopoietic stem cell transplantation. The majority of PTLD is of B-cell origin and associated with Epstein–Barr virus (EBV infection. PTLD generally display involvement of extranodal sites, aggressive histology and aggressive clinical behavior. The molecular pathogenesis of PTLD involves infection by oncogenic viruses, namely Epstein-Barr virus, as well as genetic or epigenetic alterations of several cellular genes. At variance with lymphoma arising in immunocompetent hosts, whose genome is relatively stable, a fraction of PTLD are characterized by microsatellite instability as a consequence of defects in the DNA mismatch repair mechanism. Apart from microsatellite instability, molecular alterations of cellular genes recognized in PTLD include alterations of cMYC, BCL6, TP53, DNA hypermethylation, and aberrant somatic hypermutation of protooncogenes. The occurrence of IGV mutations in the overwhelming majority of PTLD documents that malignant transformation targets germinal centre (GC B-cells and their descendants both in EBV–positive and EBV–negative cases. Analysis of phenotypic markers of B-cell histogenesis, namely BCL6, MUM1 and CD138, allows further distinction of PTLD histogenetic categories. PTLD expressing the BCL6+/MUM1+/-/CD138- profile reflect B-cells actively experiencing the GC reaction, and comprise diffuse large B-cell lymphoma (DLBCL centroblastic and Burkitt lymphoma. PTLD expressing the BCL6-/MUM1+/CD138- phenotype putatively derive from B-cells that have concluded the GC reaction, and comprise the majority of polymorphic PTLD and a fraction of DLBCL immunoblastic. A third group of PTLD is reminiscent of post-GC and preterminally differentiated B-cells that show the BCL6-/MUM1+/CD138+ phenotype, and are morphologically represented by either polymorphic PTLD or DLBCL immunoblastic.

    The X-linked lymphoproliferative syndrome is triggered by Epstein-Barr virus infection and results in fatal mononucleosis, immunodeficiency, and lymphoproliferative disorders. This study shows that the mutation responsible for X-linked lymphoproliferative syndrome is genetically linked to a restriction fragment length polymorphism detected with the DXS42 probe (from Xq24-q27). The most likely recombination frequency between the loci is 4%, and the associated logarithm of the odds is 5.26. Haplotype analysis using flanking restriction fragment length polymorphism markers indicates that the locus for X-linked lymphoproliferative syndrome is distal to probe DXS42 but proximal to probe DXS99 (from Xq26-q27). It is now possible to predict which members of a family with X-linked lymphoproliferative syndrome are carrier females and to diagnose the syndrome prenatally.

    After acute infection of Epstein-Barr virus, Epstein-Barr virus-infected B cells survive but usually do not show clonal proliferation. However, Epstein-Barr virus-infected B cells occasionally acquire a proliferative capacity that provokes clonal lymphoproliferative disorders. We herein present a case with Epstein-Barr virus-infected CD30+ B cell and immunoglobulin G4+ plasmacytoid cell proliferation in the lymph nodes, suggesting a pathological and clinical interaction between Epstein-Barr virus-associated B-cell lymphoproliferative disorders and immunoglobulin G4-related disease. Immunoglobulin G4-related disease has been recognized as a benign disease with proliferation of IgG4-related disease+ plasmacytoid cells. Several studies have recently reported the coexistence of immunoglobulin G4-related disease+ plasmacytoid cells with Epstein-Barr virus-infected B cells in lymph nodes in some immunoglobulin G4-related disease cases. However, the pathogenic role of the clonal proliferation of Epstein-Barr virus-infected B cells in immunoglobulin G4-related disease, as well as the treatments for patients with both Epstein-Barr virus-infected B cells and immunoglobulin G4-related disease, have never been discussed. A 50-year-old Japanese man was referred to us for persistent fatigue and lymphadenopathy. His blood examination showed elevated IgG4, and detected high levels of Epstein-Barr virus DNA. A lymph node biopsy revealed IgG4+ plasmacytoid cells and infiltration of large lymphoid cells, which were positive for CD20, CD30, Epstein-Barr virus-related late membrane protein 1, and Epstein-Barr virus-encoded RNA, and were negative for IgG4. Based on the diagnosis of both Epstein-Barr virus-associated B-cell lymphoproliferative disorder and IgG4-related disease, the patient received eight cycles of rituximab combined with cyclophosphamide and prednisolone, which resulted in the complete disappearance of lymphadenopathy. Moreover, his serum IgG4 level was significantly

    Epstein-Barr virus (EBV) is present in B cells in the blood of healthy people; few studies have looked for EBV in other cell types in blood from patients with lymphoproliferative disorders. We use a new technique combining immunofluorescent cell-surface staining and fluorescent in situ hybridization to quantify both EBV copy number per cell and cell types in blood from patients with high EBV DNA loads. In addition to CD20(+) B cells, EBV was present in plasmablast/plasma cells in the blood of 50% of patients, in monocytes or T cells in a small proportion of patients, and in "non-B, non-T, non-monocytes" in 69% of patients. The mean EBV copy number in B cells was significantly higher than in plasmablast/plasma cells. There was no correlation between EBV load and virus copy number per cell. Although we detected CD21, the EBV B-cell receptor, on EBV-infected B cells, we could not detect it on virus-infected T cells. These findings expand the range of cell types infected in the blood. Determining the number of EBV genomes per cell and the type of cells infected in patients with high EBV loads may provide additional prognostic information for the development of EBV lymphoproliferative diseases.

    Full Text Available Primary effusion lymphoma (PEL is a subtype of non-Hodgkin lymphoma that presents as serous effusions without detectable masses or organomegaly. Here we report a case of PEL-like lymphoma in a patient with past asbestos exposure. A 65-year-old man was referred to our hospital due to dyspnea upon exertion. He had been exposed to asbestos for three years in the construction industry. Chest X-ray and CT images demonstrated left pleural effusion. Cytological analysis of the pleural effusion revealed large atypical lymphocytes with distinct nuclear bodies and high nucleus-to-cytoplasm ratio. Immunohistochemical analyses showed that the cells were CD20+, CD3−, CD5−, and CD10−. These findings led to a diagnosis of diffuse large B-cell lymphoma. PEL or PEL-like lymphoma should be considered a potential cause of pleural effusion in subjects with past asbestos exposure.

    Since its discovery as the first human tumor associated virus, Epstein-Barr virus (EBV) has been implicated in the development of a wide range of B-cell lymphoproliferative disorders, including Burkitt' slymphoma, classic Hodgkin' s lymphoma and lymphomas arising in immunocompromised individuals (posttransplant and HIV-associated lymphoproliferative disorders). T-cell lymphoproliferative disorders that have been reported to be EBV associated include a subset of peripheral T-cell lymphomas, angioimmunoblastic T-cell lymphoma, extranodal nasal type natural killer/T-cell lymphoma, and other rare histotypes. EBV encodes a series of products interacting with or exhibiting homology to wide variety of antiapoptotic molecules,cytokines, and signal transducers, hence promoting EBV infection, immortalization and transformation.However, the exact mechanism by which EBV promotes oncogenesis is still an area of active debate. This review is focused on the pathology, diagnosis, classification, and pathogenesis of EBV-associated lymphomas.Recent advances in EBV cell-based immunotherapy, which is beginning to show promise in the treatment of EBV-related disorders, are discussed.%自从EB病毒(EBV)作为第一种人类肿瘤病毒被发现以来,EBV已涉及广泛的B细胞淋巴增生性疾病(LPD)的发生,包括伯基特(Burkitt)淋巴瘤、经典的霍奇金淋巴瘤(cHL)及免疫减损个体发生的淋巴瘤(移植后和HIV相关的LPD).EBV相关的T细胞LPD已有报道,包括外周T细胞淋巴瘤、血管性免疫母细胞性T细胞淋巴瘤及其他罕见的组织学类型.EBV编码一系列与之相互作用或同源的产物,它包括多种抗凋亡分子、细胞因子和信号转导蛋白,从而促进EBV感染、无限增生化(永生)和转化.EBV促发肿瘤的确切机制正在被活跃地思考和讨论中.文章重点综述EBV相关淋巴瘤的病理学、诊断、分类、发病学以及以EBV的细胞为基础的免疫治疗用于EBV相关疾病,后者在临床应用中已展示希望.

    Epstein-Barr virus-related post-transplant lymphoproliferative disorders are recognized as a significant cause of morbidity and mortality in patients undergoing hematopoietic stem cell transplantation. To better define current understanding of post-transplant lymphoproliferative disorders in stem cell transplant patients, and to improve its diagnosis and management, a working group of the Sixth European Conference on Infections in Leukemia 2015 reviewed the literature, graded the available quality of evidence, and developed evidence-based recommendations for diagnosis, prevention, prophylaxis and therapy of post-transplant lymphoproliferative disorders exclusively in the stem cell transplant setting. The key elements in diagnosis include non-invasive and invasive methods. The former are based on quantitative viral load measurement and imaging with positron emission tomography; the latter with tissue biopsy for histopathology and detection of Epstein-Barr virus. The diagnosis of post-transplant lymphoproliferative disorder can be established on a proven or probable level. Therapeutic strategies include prophylaxis, preemptive therapy and targeted therapy. Rituximab, reduction of immunosuppression and Epstein-Barr virus-specific cytotoxic T-cell therapy are recommended as first-line therapy, whilst unselected donor lymphocyte infusions or chemotherapy are options as second-line therapy; other methods including antiviral drugs are discouraged.

    Human herpesvirus 8 (HHV-8) is a new virus which has been reported in Kaposi's sarcoma and some lymphoproliferative disorders such as Castleman's disease and body-cavity-based lymphoma. Because HHV-8 shares homology with Epstein-Barr virus (EBV), we searched for the presence of HHV-8 DNA sequences in various cutaneous T- and B-cell lymphoma by the polymerase chain reaction (PCR). Forty-seven HIV-negative patients with cutaneous lymphoma or large plaque parapsoriasis were enrolled in the study. For the detection of HHV-8 DNA sequences we used PCR followed by a hybridization with a digoxigenin-labelled probe and nested-PCR. HHV-8 DNA sequences could only be detected in a patient with large plaque parapsoriasis. Our study does not suggest any direct implication of HHV-8 in the pathogenesis of most cutaneous lymphoma. Serological studies will be helpful to appreciate if there is an epidemiological link between HHV-8 and cutaneous lymphomas.

    Post-transplant lymphoproliferative disorders (PTLDs) are well characterized in tissue sections, but their evaluation in exfoliative cytology specimens is limited. This study reports a 25-year experience with PTLDs in exfoliative cytology specimens. All solid organ or allogeneic stem cell transplant recipients with PTLDs and exfoliative cytology specimens from 1987 to 2011 were identified. The cytomorphology, Epstein-Barr virus (EBV) status, flow cytometry, immunohistochemistry, and molecular studies were reviewed from all exfoliative cytology specimens previously diagnosed as atypical lymphoid proliferations or PTLDs. A total of 55 patients (age range, 1-72 years) with PTLDs had 434 exfoliative cytology specimens. Thirty-six of the 55 patients (65%) had 54 specimens with abnormal lymphoid proliferations (12% of the specimens), and 26 of these patients had 37 specimens available for review (15 cerebrospinal fluid specimens, 12 peritoneal fluid specimens, 9 pleural fluid specimens, and 1 bronchoalveolar lavage fluid specimen). Thirty percent of the reviewed cytology specimens were diagnostic of PTLDs, including 8 cases of monomorphic post-transplant lymphoproliferative disorder (M-PTLD) with abnormal B/T-cell populations identified with flow cytometry/immunohistochemistry and 3 EBV-positive specimens with a differential diagnosis of polymorphic PTLD versus M-PTLD. All cases diagnostic of a PTLD had 1 to 3 ancillary studies performed. Forty percent of the cytology specimens (15 of 37) were suspicious for a PTLD, but ancillary studies were performed for only a third of them, and they did not support a definitive diagnosis of a PTLD. Thirty percent of the cytology specimens (11 of 37) appeared reactive, but they lacked sufficient ancillary studies to exclude a PTLD. Atypical lymphoid proliferations are common in exfoliative cytology specimens from patients with PTLDs, and they require ancillary studies at least including immunophenotyping and EBV evaluations for a

    The CD3(-)CD4(+) lymphoid variant of hypereosinophilic syndrome is characterized by hypereosinophilia and clonal circulating CD3(-)CD4(+) T cells. Peripheral T-cell lymphoma has been described during this disease course, and we observed in our cohort of 23 patients 2 cases of angio-immunoblastic T-cell lymphoma. We focus here on histopathological (n=12 patients) and immunophenotypic (n=15) characteristics of CD3(-)CD4(+) lymphoid variant of hypereosinophilic syndrome. Atypical CD4(+) T cells lymphoid infiltrates were found in 10 of 12 CD3(-)CD4(+) L-HES patients, in lymph nodes (n=4 of 4 patients), in skin (n=9 of 9) and other extra-nodal tissues (gut, lacrymal gland, synovium). Lymph nodes displayed infiltrates limited to the interfollicular areas or even an effacement of nodal architecture, associated with proliferation of arborizing high endothelial venules and increased follicular dendritic cell meshwork. Analysis of 2 fresh skin samples confirmed the presence of CD3(-)CD4(+) T cells. Clonal T cells were detected in at least one tissue in 8 patients, including lymph nodes (n=4 of 4): the same clonal T cells were detected in blood and in at least one biopsy, with a maximum delay of 23 years between samples. In the majority of cases, circulating CD3(-)CD4(+) T cells were CD2(hi) (n=9 of 14), CD5(hi) (n=12 of 14), and CD7(-)(n=4 of 14) or CD7(low) (n=10 of 14). Angio-immunoblastic T-cell lymphoma can also present with CD3(-)CD4(+) T cells; despite other common histopathological and immunophenotypic features, CD10 expression and follicular helper T-cell markers were not detected in lymphoid variant of hypereosinophilic syndrome patients, except in both patients who developed angio-immunoblastic T-cell lymphoma, and only at T-cell lymphoma diagnosis. Taken together, persistence of tissular clonal T cells and histopathological features define CD3(-)CD4(+) lymphoid variant of hypereosinophilic syndrome as a peripheral indolent clonal T-cell lymphoproliferative

    HCV can lead to both chronic liver disease and B-cell lymphoproliferative disorders. A strong association exists between HCV and mixed cryoglobulinaemia (MC). Anti-nuclear antibodies (ANA), rheumatoid factor Ig-G (RF-IgG), free light chain κ and λ (FLC-κ, FLC-λ) levels and κ/λ ratio were evaluated in 50/420 subjects unexpectedly resulted anti-HCV positive after routine screenings for non-hepathological procedures. Three/fifty patients had HCV-RNA undetectable in the serum and were excluded from the analysis. Thirty-nine/fifty patients had laboratory evidence of circulating cryoglobulins without liver disease and MC-related symptoms. Among them, 17 resulted ANA-positive. The mean cryocrit was higher in ANA-positive patients, while no other demographic/clinical differences were observed between the groups. Significantly higher levels of RF-IgG were observed in ANA-positive vs ANA-negative patients. κ and λ FLC were higher in ANA-positive patients. A ROC analysis, based on ANA-positivity vs ANA-negativity, confirmed a high sensitivity and specificity of RF-IgG test. Published data concerning MC come mostly from symptomatic vasculitis. We analyzed HCV-patients without MC symptoms, founding cryoglobulins in the majority of them. The increased levels of FR-IgG and FLC in CGs-ANA-positive patients, suggest these test could be used to identify a state of silent autoimmune and/or lymphoproliferative condition before the transition to a frank disease in naïve HCV-patients without symptoms of extrahepatic manifestations.

    We report a rare case in which Epstein-Barr virus (EBV)-negative polymorphic B-cell post-transplant lymphoproliferative disorder (PTLD) and EBV-negative monomorphic T-cell PTLD [anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALCL)] were observed simultaneously in the same cervical lymph node, 34 months after liver transplantation for hepatitis C liver cirrhosis. Although hepatitis C recurred after 2 months, he had no other complications until PTLD occurred 34 months post-transplantation. The patient underwent reduction of the immunosuppressive drug and rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone therapy, and he was considered to have achieved complete remission. However, PTLD recurred, and he died 6 months after the initial diagnosis. Autopsy revealed only EBV-negative monomorphic T-cell PTLD (ALK-negative ALCL) that involved the liver, spleen, bilateral kidneys, stomach, bladder, heart, bone marrow, right ureter, and pons. Thus, recurrent PTLD may show a different histological type from the primary disorder, as PTLD has a multiclonal potentiality that causes various types of lymphomas. Therefore, it may be difficult to predict PTLD-related prognosis from the initial PTLD histological identification.

    Full Text Available Epstein-Barr virus (EBV encodes two non-polyadenylated RNAs termed EBV-encoded RNAs (EBERs. In this study, we tried to find series in which data of EBER and onset time of post-transplant lymphoproliferative disorder (PTLD for patients have been documented to conduct a meta-analysis. A comprehensive search of the literature was performed by Pubmed and Google scholar to find reports indicating test results for EBER and PTLD onset in transplant patients. PTLD was considered "early onset" when it develops within the first post-transplant year. Finally, 265 patients from 15 studies have been included in the meta-analysis. The overall meta-analysis also showed a significant relation between EBER test positivity and early-onset PTLD development [relative risk (RR: 1.36; 95% CI: 1.16-1.59; P <0.001]. The i2 index was 49.8%. Our study suggests that PTLD lesions with positive EBER test are more likely to develop within the early post-transplant period. Since early-onset PTLD is supposed to have better prognosis, having a positive EBER test might not be a bad news. However, for having a precise conclusion, prospective studies are needed to be conducted.

  13. EBV-associated post-transplantation B-cell lymphoproliferative disorder following allogenic stem cell transplantation for acute lymphoblastic leukaemia: tumor regression after reduction of immunosuppression - a case report

    Full Text Available Abstract Epstein-Barr virus (EBV-associated B-cell post-transplantation lymphoproliferative disorder (PTLD is a severe complication following stem cell transplantation. This is believed to occur as a result of iatrogenic immunosuppression leading to a relaxation of T-cell control of EBV infection and thus allowing viral reactivation and proliferation of EBV-infected B-lymphocytes. In support of this notion, reduction of immunosuppressive therapy may lead to regression of PTLD. We present a case of an 18-year-old male developing a monomorphic B-cell PTLD 2 months after receiving an allogenic stem cell transplant for acute lymphoblastic leukemia. Reduction of immunosuppressive therapy led to regression of lymphadenopathy. Nevertheless, the patient died 3 months afterwards due to extensive graft-vs.-host-disease and sepsis. As a diagnostic lymph node biopsy was performed only after reduction of immunosuppressive therapy, we are able to study the histopathological changes characterizing PTLD regression. We observed extensive apoptosis of blast cells, accompanied by an abundant infiltrate comprising predominantly CD8-positive, Granzyme B-positive T-cells. This observation supports the idea that regression of PTLD is mediated by cytotoxic T-cells and is in keeping with the observation that T-cell depletion, represents a major risk factor for the development of PTLD.

    We analyzed CpG-island hypermethylation status in 12 genes of paraffin-embedded tissues from 38 rheumatoid arthritis (RA) patients with methotrexate (MTX)-associated large B cell lymphoproliferative disorder (BLPD), 11 RA patients with non-MTX-associated BLPD (non-MTX-BLPD), 22 controls with diffuse large B cell lymphoma (DLBCL), and 10 controls with Epstein-Barr virus (EBV)(+) DLBCL. Among them, tumor cells from EBV(+) MTX-BLPD patients and control EBV(+) DLBCL patients had significantly lower median incidence of CpG island methylator phenotype (CIMP) than those from non-MTX-BLPD and control DLBCL groups (2.3 and 1.7 vs. 4.3 and 4.4; P < 0.01 for each). In the MTX-BLPD group, EBV(+) patients showed lower median CIMP than EBV(-) patients (2.3 vs. 3.2); they also had significantly lower hypermethylation incidence in four apoptosis-related genes, especially death-associated protein kinase (14 vs. 55 %), higher incidence of massive tumor necrosis (86 vs. 27 %), and lower BCL2 protein expression (19 vs. 86 %) than did the control DLBCL group (P < 0.01 for all). In all clinical stages, EBV(+) MTX-BLPD patients had better prognoses than the EBV(-) MTX-BLPD (P = 0.011), non-MTX-BLPD (P = 0.002), and control DLBCL groups (P = 0.015). MTX-BLPD patients without hypermethylated RAS-associated domain family-1A (RASSF1A) or O (6) -methyl guanine-DNA methyltransferase (MGMT) had significantly better prognosis than those with hypermethylation of those genes (P = 0.033). We conclude that in RA patients with MTX-BLPD, EBV infection is associated with a lower incidence of CIMP, apoptosis-related gene hypermethylation, and BCL2 expression, which can induce tumor regression by MTX withdrawal and lead to better prognoses.

    Polyclonal Epstein-Barr virus (EBV)-infected B cell line (lymphoblastoid cell lines; LCL)-stimulated T-cell preparations have been successfully used to treat EBV-positive post-transplant lymphoproliferative disorders (PTLD) in transplant recipients, but function and specificity of the CD4+ component are still poorly defined. Here, we assessed the tumor-protective potential of different CD4+ T-cell specificities in a PTLD-SCID mouse model. Injection of different virus-specific CD4+ T-cell clones showed that single specificities were capable of prolonging mouse survival and that the degree of tumor protection directly correlated with recognition of target cells in vitro. Surprisingly, some CD4+ T-cell clones promoted tumor development, suggesting that besides antigen recognition, still elusive functional differences exist among virus-specific T cells. Of several EBV-specific CD4+ T-cell clones tested, those directed against virion antigens proved most tumor-protective. However, enriching these specificities in LCL-stimulated preparations conferred no additional survival benefit. Instead, CD4+ T cells specific for unknown, probably self-antigens were identified as principal antitumoral effectors in LCL-stimulated T-cell lines. These results indicate that virion and still unidentified cellular antigens are crucial targets of the CD4+ T-cell response in this preclinical PTLD-model and that enriching the corresponding T-cell specificities in therapeutic preparations may enhance their clinical efficacy. Moreover, the expression in several EBV-negative B-cell lymphoma cell lines implies that these putative autoantigen(s) might also qualify as targets for T-cell-based immunotherapy of virus-negative B cell malignancies.

    2013-07-01

    Meige's syndrome is a rare neurological syndrome characterized by oromandibular dystonia and blepharospasm. Its pathophysiology is not clearly determined. A 35-year-old female presented to psychiatric department with blepharospasm and oromandibular dystonia with clinical provisional diagnosis of psychiatric disorder (Conversion Disorder). After thorough physical examination including detailed neurological exam and psychiatric evaluation no formal medical or psychiatric diagnosis could be made. The other differential diagnoses of extra pyramidal symptom, tardive dyskinesia, conversion disorder, anxiety disorder were ruled out by formal diagnostic criteria. Consequently with suspicion of Meige's syndrome she was referred to the department of Neurology and the diagnosis was confirmed. Hence, Meige's syndrome could be misdiagnosed as a psychiatric disorder such as conversion disorder or anxiety disorder because clinical features of Meige's syndrome are highly variable and affected by psychological factors and also can be inhibited voluntarily to some extent.

    High-dose immunosuppressive therapy followed by autologous hematopoietic stem cell transplantation (HSCT) is currently being evaluated for the control of severe autoimmune diseases. The addition of antithymocyte globulin (ATG) to high-dose chemoradiotherapy in the high-dose immunosuppressive therapy regimen and CD34 selection of the autologous graft may induce a higher degree of immunosuppression compared with conventional autologous HSCT for malignant diseases. Patients may be at higher risk of transplant-related complications secondary to the immunosuppressed state, including Epstein-Barr virus (EBV)-associated posttransplantation lymphoproliferative disorder (PTLD), but this is an unusual complication after autologous HSCT. Fifty-six patients (median age, 42 years; range, 23-61 years) with either multiple sclerosis (n = 26) or systemic sclerosis (n = 30) have been treated. The median follow-up has been 24 months (range, 2-60 months). Two patients (multiple sclerosis, n = 1; systemic sclerosis, n = 1) had significant reactivations of herpesvirus infections early after HSCT and then developed aggressive EBV-PTLD and died on days +53 and +64. Multiorgan clonal B-cell infiltrates that were EBV positive by molecular studies or immunohistology were identified at both autopsies. Both patients had positive screening skin tests for equine ATG (Atgam) and had been converted to rabbit ATG (Thymoglobulin) from the first dose. Of the other 54 patients, 2 of whom had partial courses of rabbit ATG because of a reaction to the intravenous infusion of equine ATG, only 1 patient had a significant clinical reactivation of a herpesvirus infection (herpes simplex virus 2) early after HSCT, and none developed EBV-PTLD. The T-cell count in the peripheral blood on day 28 was 0/microL in all 4 patients who received rabbit ATG; this was significantly less than in patients who received equine ATG (median, 174/microL; P =.001; Mann-Whitney ranked sum test). Although the numbers are limited

    Full Text Available Hepatitis C virus (HCV has been identified as one of the major risk factors for type II mixed cryoglobulinemia (MC, during the clinical evolution of chronic hepatitis, which may lead to development of B cell non-Hodgkin's lymphoma (NHL. We have previously shown that the candidate idiotype vaccine, based on the IGKV3-20 light chain protein, is able to induce activation and maturation of circulating antigen presenting cells (APCs in both HCV-positive and HCV-negative healthy control subjects, with production of Th2-type cytokines. Here, the effect of the recombinant IGKV3-20 protein on human peripheral blood mononuclear cells (PBMCs from HCV-positive subjects, with known blood levels of cryoglobulins, is shown via gene expression profiling analysis combined to multiparameter flow cytometry and multiplex analyses of cytokines.

    performed in order to assess 8 cases of lymphoid interstitial pneumonia (LIP and 7 cases of pulmonary lymphoproliferative disorders. RESULTS: All 8 cases of LIP presented moderate to strong immunostaining for CD3, compared with only 2 cases of lymphoma and 1 case of pseudolymphoma (p = 0.02. Gene rearrangement was detected in 4 of the 8 cases, which changed the diagnosis from LIP to lymphoma, showing the importance of gene rearrangement detection in cases of LIP. In this situation, gene rearrangement using the VH/JH and Vgamma11/Jgamma12 primer pairs was detected in 3 cases and 1 case, respectively, and no gene abnormalities were found using the Dbeta1/Jbeta2 and Vgamma101/Jgamma12 primer pairs in any of the cases. A significant positive association was found between the intensity of CD20 and CD68 expression and gene rearrangement using the VH/JH primer pair. Prior to the gene rearrangement, 4 patients with LIP died quickly, whereas only one patient with LIP died after the gene rearrangement. CONCLUSIONS: Detection of monoclonal B and T cells by immunophenotyping and polymerase chain reaction had an impact on the diagnosis of pulmonary lymphomas in patients previously diagnosed with LIP. Therefore, immunophenotyping and polymerase chain reaction should be used as 'gold standard' techniques in routine practice.

    Autoimmune Lymphoproliferative syndrome (ALPS) is an inherited disorder manifesting with autoimmune cytopenia, lymphadenopathy and splenomegaly. The differential diagnosis includes infections, autoimmune disorders or malignancies. The disease is characterized by accumulation of double negative (CD3+ CD4- CD8-) T cells (DNT) in the peripheral blood. We describe a case and review the literature.

    Autoimmune lymphoproliferative syndrome (ALPS), a disorder characterized by immune dysregulation due to disrupted lymphocyte homeostasis, is mainly resulted from the mutations in FAS-mediated apoptotic pathway. In addition, other mutations of the genes such as Fas-ligand (FASLG), Caspase 10 (CASP10) and Caspase 8 (CASP8), NRAS and KRAS have also been observed in a small number of patients with ALPS or ALPS-related disorders. However, approximately 20-30% of patients with ALPS have unidentified defect. Its clinical manifestations observed in multiple family members include unexplained lymphadenopathy, hepatosplenomegaly, autoimmune cytopenias such as thrombocytopenia, neutropenia, and anemia due to excessive production of antibodies by lymphocytes, elevated number of double-negative T (DNT) cells, and increased risk of lymphoma. As a very rare disease, ALPS was first characterized in the early 1990s. More than 300 families with hereditary ALPS have been reported till now; nearly 500 patients from these families have been studied and followed worldwide over the last 20 years. ALPS has historically considered as a primary immune defect presenting in early childhood, however, recent studies have shown that it may be more common than previous thought because adult onset presentation is increasingly becoming recognized and more adult ALPS patients are diagnosed. The new genetic and biological insights have improved the understanding of ALPS and a number of targeted therapeutic strategies such as mycophenolate mofetil, sirolimus, and pentostatin have been successfully applied in ALPS patients with promising treatment efficacy. This article comprehensively reviews the clinical and laboratory manifestations, new research advances in the molecular pathogenesis, diagnosis and treatments of this disorder.

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of abnormal lymphocyte homeostasis, resulting from mutations in the Fas apoptotic pathway. Clinical manifestations include noninfectious and nonmalignant lymphadenopathy, splenomegaly, and autoimmune pathology-most commonly, autoimmune cytopenias. Rarely, and in association with specific genetic mutations, patients with ALPS may go on to develop secondary lymphoid malignancies. Though ALPS is a rare disorder, it should be suspected and ruled out in children presenting with chronic and refractory multilineage cytopenias associated with nonmalignant lymphoproliferation. Revised diagnostic criteria and insights into disease biology have improved both diagnosis and treatment. Sirolimus and mycophenolate mofetil are the best-studied and most effective corticosteroid-sparing therapies for ALPS, and they should be considered first-line therapy for patients who need chronic treatment. This review highlights practical clinical considerations for diagnosis and management of ALPS.

    Full Text Available Obsessive-compulsive disorder (OCD is one of the most prevalent psychiatric disorders in children and adolescents. The phenomenology of OCD in children and adolescent is strikingly similar to that of adults. But at times, the presentation of OCD may be so atypical or unusual in children and adolescents that may lead to misdiagnosis or delay in diagnosis. We report a case of 10-year-old child who was initially misdiagnosed with schizophrenia, and treated with antipsychotic for 2 months. But once the core symptoms were recognized as obsessions and compulsions and appropriately treated in the line of OCD, the symptoms resolved significantly.

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of abnormal lymphocyte survival caused by defective Fas-mediated apoptosis, leading to lymphadenopathy, hepatosplenomegaly, and an increased number of double-negative T cells (DNTs). Treatment options for patients with ALPS are limited. Rapamycin has been shown to induce apoptosis in normal and malignant lymphocytes. Since ALPS is caused by defective lymphocyte apoptosis, we hypothesized that rapamycin would be effective in treating ALPS. We tested this hypothesis using rapamycin in murine models of ALPS. We followed treatment response with serial assessment of DNTs by flow cytometry in blood and lymphoid tissue, by serial monitoring of lymph node and spleen size with ultrasonography, and by enzyme-linked immunosorbent assay (ELISA) for anti-double-stranded DNA (dsDNA) antibodies. Three-dimensional ultrasound measurements in the mice correlated to actual tissue measurements at death (r = .9648). We found a dramatic and statistically significant decrease in DNTs, lymphadenopathy, splenomegaly, and autoantibodies after only 4 weeks when comparing rapamycin-treated mice with controls. Rapamycin induced apoptosis through the intrinsic mitochondrial pathway. We compared rapamycin to mycophenolate mofetil, a second-line agent used to treat ALPS, and found rapamycin's control of lymphoproliferation was superior. We conclude that rapamycin is an effective treatment for murine ALPS and should be explored as treatment for affected humans.

    An unusual lymphoproliferative disease was identified in multiple closely related British Shorthair (BSH) kittens, suggesting an inherited predisposition to disease. Affected kittens typically developed rapidly progressive and marked generalized lymphadenopathy, moderate splenomegaly, and regenerative and likely hemolytic anemia from 6 weeks of age. Microscopic findings were suggestive of multicentric T-cell lymphoma, but additional testing revealed a polyclonal population of CD3+/CD4-/CD8- "double negative" T cells (DNT cells). This is a novel disease presentation with similarities to the human disorder autoimmune lymphoproliferative syndrome (ALPS), a rare inherited disease causing lymphoproliferation and variable manifestations of autoimmunity. The human disease is most commonly due to the presence of Fas gene mutations causing defective lymphocyte apoptosis, and further investigations of both the mode of inheritance and genetic basis for disease in affected cats are currently in progress.

    Sheehan's syndrome or Simmond's disease is a rare endocrine disorder seen in clinical practice. The clinical spectrum is diverse and a high index of suspicion together with a good clinical acumen and proper diagnostic approach helps in early diagnosis and prompt treatment of this endocrinopathy. Sheehan's syndrome presenting as a major depressive disorder finds less mention in the literature. The patient discussed here is a 45-year-old female who had been on antidepressants and psychiatry follow up for a long time until she presented to our Out Patient Department (OPD), where she was evaluated in detail and diagnosed as a case of Sheehan's syndrome. The patient is doing well and is on a regular follow-up with us. Further studies are required to demystify the strength of this association in more detail and to elucidate the possible underlying mechanism.

    Hallett, Mark

    2016-01-01

    Functional or psychogenic movement disorders are common and disabling, and sometime difficult to diagnose. The history and physical exam can give positive features that will support the diagnosis, which should not be based solely on exclusion. Some clues in the history are sudden onset, intermittent time course, variability of manifestation over time, childhood trauma, history of other somatic symptom and secondary gain. Anxiety and depression are common, but not necessarily more than the general population. On examination, distraction and suggestibility may be present. There are specific signs that should be looked for with different types of movements. For example, with tremor, change in frequency over time and entrainment are common features. With myoclonus, the movements might be complex in type with long latencies to stimulus induced jerks. Gait disorders show good balance despite claims to the contrary. Functional dystonia still remains a challenging diagnosis in many circumstances, although fixed dystonia is one sign more likely to be functional.

    Full Text Available Posttraumatic stress disorder (PTSD has been a controversial diagnosis, with concerns including the sheer number of possible minimal diagnostic combinations (1,750, increasing to >10,000 theoretical possibilities in Diagnostic and Statistical Manual of Mental Disorders (5th ed. proposals. This study examined whether the theoretical combinations postulated actually occur in a large sample of military personnel. The design of the study was a retrospective examination of PTSD checklists from 3,810 participants who, based on scores, endorsed symptoms consistent with probable PTSD. Combinations of PTSD Checklist–Civilian Version (PCL-C symptom clusters were identified using data from active-duty military personnel who completed the 2005 and the 2008 Department of Defense (DoD Health Related Behaviors Among Active Duty Military Personnel Survey. The study examined (a occurrence of combinations, (b unique minimum combinations, (c most frequent combinations, and (d replication of symptom combinations and clusters. The PCL-C scores showed 1,837 unique scoring combinations, 83.5% (1,533/1,837 of the observed unique scoring combinations occurred just once. The most frequently occurring combination (17/17 endorsed accounted for 955 participants (25.1%, the second most frequent (16/17 endorsed accounted for 75 participants (2.0%. PTSD most often presented as a unique constellation of symptom clusters, either capturing symptoms while allowing for considerable variability in its presentation, reflecting different severities of the disorder, or raising concerns about the classification itself, and any future classification that Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-V might develop.

    Full Text Available The last decade has witnessed a surge of awareness about autism among the public and professionals. Much revealing research is being done on this issue and the knowledge base has improved substantially and a set of professionals are specializing on the subject, focusing on its causative factors and management. Autism being a disorder stemming from early childhood and the prevalence rate rising alarmingly over the years, Pediatricians are expected to play a vital role in early detection and early intervention in management of the problem. But, unfortunately, autism is not yet considered to be under the purview of pediatricians. As pediatricians, we are often perplexed when faced with such a different child in our office and either overlook the problem or hurry to hand him over to a psychiatrist, not trying to really identify and understand the problem as a medical entity ourselves. Hence better awareness among pediatricians is the need of the day. As specialists have worked with autism over the decades, it has become clear that: autism is a disorder that involves early development, presently there is no medical answer to autism, and the only management strategy hinges largely on effective training. The earlier the training begins the better it is for the child. It is of paramount importance to start training and bring about changes by the time the child is 18 months old. This throws up interesting new challenges to the profession of pediatrics. To identify the early warning signs of autism, it is important that Pediatricians are able to recognize the signs and symptoms of autistic spectrum disorders (ASD, have a strategy for assessing them systematically, be familiar with available tools for screening as well as developmental and educational resources.DOI: http://dx.doi.org/10.3126/jcmsn.v10i3.12775 Journal of College of Medical Sciences-Nepal, 2014, Vol-10, No-3, 37-47

    2015-01-01

    Nonorganic vision loss accounts for up to 5% of patients and presents in two forms, malingering and visual conversion disorder (VCD). It is described a case of VCD in a new mother struggling both with her husband being deployed overseas and the recent death of her father. In addition, she had been evaluated for a concussion secondary to a motor vehicle accident three months prior. An inexpensive series of clinical tests were performed to rule out organic disease and obtained equivocal results. Some tests revealed intact vision in the affected eye while others supported a neurological cause for the vision loss. However, the patient quickly recovered normal visual acuity when encouraged to discuss situations that have been causing emotional stress. This almost immediate recovery of vision confirmed the diagnosis of VCD. This report should make primary eye care professionals more aware of visual conversion disorder and its clinical evaluation.

The frequent genetic alterations that modify neurofibromin function are deletions and insertions. Duplications are rare and phenotype in patients bearing duplication of NF1 gene is thought to be restricted to developmental abnormalities, with no reference to cancer susceptibility in these patients. We evaluated a patient who presented with few clinical signs of neurofibromatosis type 1 and a conspicuous personal and familiar history of different types of cancer, especially lymphoproliferative malignancies. The coding region of the NF-1 gene was analyzed by real-time polymerase chain reaction and direct sequencing. Multiplex ligation-dependent probe amplification was performed to detect the number of mutant copies. The NF1 gene analysis showed the following alterations: mosaic duplication of NF1, TRAF4, and MYO1D. Fluorescence in situ hybridization using probes (RP5-1002G3 and RP5-92689 flanking NF1 gene in 17q11.2 and CEP17 for 17q11.11.1 was performed. There were three signals (RP5-1002G3conRP5-92689 in the interphases analyzed and two signals (RP5-1002G3conRP5-92689 in 93% of cells. These findings show a tandem duplication of 17q11.2. Conclusion. The case suggests the possibility that NF1 gene duplication may be associated with a phenotype characterized by lymphoproliferative disorders.

    Autoimmune lymphoproliferative syndrome (ALPS) is an uncommon nonmalignant lymphoproliferative disease which is characterized by chronic, persistent or recurrent lymphadenopathy, splenomegaly, hepatomegaly, immune cytopenia , hypergammaglobinemia and increased risk of lymphoma. We report a 2-year old boy with hepatosplenomegaly as first presentation. Petechial and purpuric rashes with massive cervical lymphadenopathies developed 10 months later.In laboratory tests anemia, thrombocytopenia and hypergammaglobinemia were observed. According to flocytometry increased double negative T cells and by apoptosis assay decrease apoptosis of lymphocytes accompanied clinical manifestations, thus diagnosis of ALPS was established. In conclusion; in all patients with massive lymphadenopathy and hepatosplenomegay; especially with cytopenia; ALPS should be considered.

    Full Text Available Neurotoxins have existed on the earth from times immemorial. Old neurotoxic disorders were due to ingestion/ exposure of heavy metals and food like lathyrus sativus over a long period of time. The 20th Century with rapid industrialsation and expanding chemical and drug industry has spawned several new, hitherto unknown disorders. Old disorders continue to exist e.g. fluorosis, arsenicosis, lathyrism, manganism and lead neuropathy, along with new diseases like Minamata disease, subacute myelo optic neuropathy (SMON, MPTP-Parkinsonian syndorme, triorthcresyl phosphate (TOCP neuroparalytic disease, pesticide induced seizures, tremor and neuropathy, solvent encephalopthy, antipileptic drug foetal syndrome and excitotoxin induced behavioural disorders. Studies on pesticides Organochlorine and organophosphates, synthetic pyrethrins, solvents, heavy metals and substances abuse in the Indian context confirm the neurotoxic nature of many synthetic substances. Future problems envisaged are of concern to clinical neurologists as many of these neurotoxic disorders mimic syndromes of well known neurological disease. The new millenium poses a challenge to the clinician as newer compounds in industry, food, drugs and chemical war agents are being developed. Molecular genetics has advanced rapidly with release of the human genome map. Animal cloning and genetically modified plant products have entered the food chain. How safe are these new inventions for the central nervous system is a big question? India cannot afford disasters like Union Carbide′s Bhopal gas leak nor be a silent spectator to manipulative biotechnology. Unless it is proven beyond all doubt to be a safe innovation, Chemicals have to be cautiously introduced in our environment. To Study, ascertain and confirm safety or neurotoxicity is an exciting challenge for the neuroscientists of the 21st century.

    Posttransplantation lymphoproliferative disorders (PTLD) are heterogeneous lesions with variable morphology, immunophenotype, and molecular characteristics. Multiple distinct primary lesions can occur in PTLD, rarely with both B-cell and T-cell characteristics. Lesions can involve both grafted organs and other sites; however, PTLD involving the pituitary gland has not been previously reported. We describe a patient who developed Epstein-Barr virus-negative PTLD 13 years posttransplantation involving the terminal ileum and pituitary, which was simultaneously involved by a pituitary adenoma. Immunohistochemistry of the pituitary lesion showed expression of CD79a, CD3, and CD7 with clonal rearrangements of both T-cell receptor gamma chain (TRG@) and immunoglobulin heavy chain (IGH@) genes. The terminal ileal lesion was immunophenotypically and molecularly distinct. This is the first report of pituitary PTLD and illustrates the potentially complex nature of PTLD.

    Epstein-Barr virus (EBV) is known to be associated with the development of lymphomas in immunocompromised patients. Recently, age-related immune impairment has been recognized as a predisposing factor in the development of EBV-driven lymphoproliferative disorders (LPDs) in elderly patients without any known immunodeficiency or prior lymphoma. In approximately 70% of reported cases, the affected sites have been extranodal, such as the skin, lung, tonsil and stomach. However, age-related EBV-associated B cell (EBV + B cell) LPD is extremely rare in the oral cavity. Here we report a 71-year-old Japanese man who developed an EBV + B cell LPD resembling classical Hodgkin lymphoma (CHL)--so-called polymorphous subtype-of the mandible. Histopathologically, infiltration of large atypical lymphoid cells including Hodgkin or Reed-Sternberg-like cells into granulation tissue with marked necrosis was found in the mandibular bone. Immunohistochemical analysis revealed that the large atypical Hodgkin or Reed-Sternberg-like cells were CD3-, CD15-, CD20+, CD30+ and Epstein-Barr virus (EBV)-latent infection membrane protein-1 (LMP-1)+. In situ hybridization (ISH) demonstrated EBV-encoded small RNA (EBER) + in numerous Hodgkin or Reed-Sternberg-like cells. EBNA-2 was detected by polymerase chain reaction (PCR) using an extract from the formalin-fixed, paraffin-embedded specimen. To our knowledge, this is the first reported case of the polymorphous subtype of age-related EBV + B cell LPD affecting the mandible.

    We compared two strategies for minimal residual disease evaluation of B-cell lymphoproliferative disorders characterized by a variable immunoglobulin heavy chain (IGH) genes mutation load. Twenty-five samples from chronic lymphocytic leukaemia (n = 18) or mantle cell lymphoma (n = 7) patients were analyzed. Based on IGH variable region genes, 22/25 samples carried > 2% mutations, 20/25 > 5%. In the IGH joining region genes, 23/25 samples carried > 2% mutations, 18/25 > 5%. Real-time quantitative polymerase chain reaction was performed on IGH genes using two strategies: method A utilizes two patient-specific primers, whereas method B employs one patient-specific and one germline primer, with different positions on the variable, diversity and joining regions. Twenty-three samples (92%) resulted evaluable using method A, only six (24%) by method B. Method B poor performance was specifically evident among mutated IGH variable/joining region cases, although no specific mutation load above, which the real-time quantitative polymerase chain reaction failed was found. The molecular strategies for minimal residual disease evaluation should be adapted to the B-cell receptor features of the disease investigated.

    Patients affected by autoimmune diseases (rheumatoid arthritis, psoriasis, dermatomyositis) who are treated with methotrexate (MTX) sometimes develop lymphoproliferative disorders (LPDs). In approximately 40% of reported cases, the affected sites have been extranodal, and have included the gastrointestinal tract, skin, lung, kidney, and soft tissues. However, MTX-associated LPD (MTX-LPD) is extremely rare in the oral cavity. Here we report a 69-year-old Japanese woman with rheumatoid arthritis (RA) who developed MTX-LPD resembling Hodgkin's disease--so-called "Hodgkin-like lesion"--in the left upper jaw. Histopathologically, large atypical lymphoid cells including Hodgkin or Reed-Sternberg-like cells were found to have infiltrated into granulation tissue in the ulcerative oral mucosa. Immunohistochemistry showed that the large atypical cells were positive for CD20, CD30 and Epstein-Barr virus (EBV)-latent infection membrane protein-1 (LMP-1) and negative for CD15. EBV was detected by in situ hybridization (ISH) with EBV-encoded small RNA (EBER), and polymerase chain reaction (PCR) for LMP-1 and EBNA-2 in material taken from the formalin-fixed, paraffin-embedded specimen. To our knowledge, this is the first reported case of MTX-related EBV-associated LPD (MTX-EBVLPD), "Hodgkin-like lesion", of the oral cavity in a patient with RA.

    Anger is present as a key criterion in five diagnoses within DSM-5: Intermittent Explosive Disorder, Oppositional Defiant Disorder, Disruptive Mood Dysregulation Disorder, Borderline Personality Disorder and Bipolar Disorder. This review amasses scientific literature demonstrating that within each of these disorders, anger is a central clinical feature that is highly prevalent and predictive of important outcomes. For each disorder, we also discuss the phenomenology and etiology of anger. Although models of anger have been quite distinct across these disorders, few empirical studies have truly tested whether anger stems from different etiological factors across these different conditions. We end with a discussion of transdiagnostic research that draws from cognitive psychology, affective science, and the neuroscience of anger, and that also fits with integrative approaches to treatment.

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of lymphocyte apoptosis. Children present with chronic nonmalignant lymphadenopathy, hepatosplenomegaly, and autoimmune cytopenias. Recent advances show efficacy of treatment with immunosuppressive drugs. Sirolimus, an mammalian target of rapamycin inhibitor, improves autoimmune cytopenias and lymphoproliferation, with a safe profile. We present 2 patients, a 5-year-old girl and 15-year-old boy, diagnosed with ALPS with initial partial response to steroid treatment. Autoimmune cytopenias and lymphoproliferation then became refractory to treatment, with recurrence of symptoms. In both cases, treatment with sirolimus was started, with a rapid response, complete remission of cytopenias, and resolution of lymphoproliferation, with no significant adverse effects.

  8. Gluten Sensitivity Presenting as a Neuropsychiatric Disorder

    Full Text Available There has been increasing recognition in the medical community and the general public of the widespread prevalence of gluten sensitivity. Celiac disease (CD was initially believed to be the sole source of this phenomenon. Signs and symptoms indicative of nonceliac gluten sensitivity (NCGS, in which classical serum and intestinal findings of CD may be absent, have been frequently reported of late. Clinical manifestations in patients with NCGS are characteristically triggered by gluten and are ameliorated or resolved within days to weeks of commencing a gluten-free diet. Emerging scientific literature contains several reports linking gluten sensitivity states with neuropsychiatric manifestations including autism, schizophrenia, and ataxia. A clinical review of gluten sensitivity is presented alongside a case illustrating the life-changing difference achieved by gluten elimination in a patient with a longstanding history of auditory and visual hallucinations. Physicians in clinical practice should routinely consider sensitivity issues as an etiological determinant of otherwise inexplicable symptoms. Pathophysiologic mechanisms to explain the multisystem symptomatology with gluten sensitivity are considered.

    Autoimmune lymphoproliferative syndrome is a rare genetic disorder characterized by defective FAS-mediated apoptosis, autoimmune disease, accumulation of mature T-cell receptor alpha/beta positive, CD4 and CD8 double-negative T cells and increased risk of lymphoma. Despite frequent hematologic abnormalities, literature is scarce regarding the bone marrow pathology in autoimmune lymphoproliferative syndrome. We retrospectively reviewed 3l bone marrow biopsies from a cohort of 240 patients with germline FAS mutations. All biopsies were performed for the evaluation of cytopenias or to rule out lymphoma. Clinical information was collected and morphological, immunohistochemical, flow cytometric and molecular studies were performed. Bone marrow lymphocytosis was the predominant feature, present in 74% (23/31) of biopsies. The lymphoid cells showed several different patterns of infiltration, most often forming aggregates comprising T cells in 15 cases, B cells in one and a mixture of T and B cells in the other seven cases. Double-negative T cells were detected by immunohistochemistry in the minority of cases (10/31; 32%); significantly, all but one of these cases had prominent double-negative T-lymphoid aggregates, which in four cases diffusely replaced the marrow space. One case showed features of Rosai-Dorfman disease, containing scattered S-100+ cells with emperipolesis and double-negative T cells. No clonal B or T cells were detected by polymerase chain reaction in any evaluated cases. Classical Hodgkin lymphoma was identified in three cases. Our results demonstrate that infiltrates of T cells, or rarely B cells, can be extensive in patients with autoimmune lymphoproliferative syndrome, mimicking lymphoma. A multi-modality approach, integrating clinical, histological, immunohistochemical as well as other ancillary tests, can help avoid this diagnostic pitfall.

    2015-09-01

    Full Text Available Body dysmorphic disorder is an obsessive-compulsive related psychiatric disorder characterized by excessive preoccupation about an imagined or slight defect in appearance. Preoccupation of the appearance with the skin, hair and nose are most common. Impairment of the quality of life, comorbidity of the psychiatric and personality disorder are related with body dysmorphic disorder. Nowadays, cosmetic procedure has become increasingly popular especially among women. The prevalence of body dysmorphic disorder among patients seeking cosmetic treatment in surgery or dermatology clinics is higher than general population. As postoperatively some patients dissatisfied with the surgery, dermatologists and surgeons should be informed about body dysmorphic disorder. This aim of this review was to assess prevalance, clinical features, motivational factors of patients with body dysmorphic disorder presenting for cosmetic medical treatments.

    Mutations in LPS-responsive and beige-like anchor (LRBA) gene were recently described in patients with combined immunodeficiency, enteropathy and autoimmune cytopenia. Here, we extend the clinical and immunological phenotypic spectrum of LRBA associated disorders by reporting on three patients from two unrelated families who presented with splenomegaly and lymphadenopathy, cytopenia, elevated double negative T cells and raised serum Fas ligand levels resembling autoimmune lymphoproliferative syndrome (ALPS) and one asymptomatic patient. Homozygous loss of function mutations in LRBA were identified by whole exome analysis. Similar to ALPS patients, Fas mediated apoptosis was impaired in LRBA deficient patients, while apoptosis in response to stimuli of the intrinsic mitochondria mediated apoptotic pathway was even enhanced. This manuscript illustrates the phenotypic overlap of other primary immunodeficiencies with ALPS-like disorders and strongly underlines the necessity of genetic diagnosis in order to provide early correct diagnosis and subsequent care.

    Full Text Available Objective: To report an unusual presenting manifestation of multiple sclerosis in a teenager. Case Report: We report the case of a 16-year-old male who was diagnosed with schizoaffective disorder a year prior to his neurological consultation. Neurological examination showed evidence of mild lower extremity spasticity with ataxia and dysarthria. Imaging revealed lesions suggestive of multiple sclerosis. Conclusion: An organic basis for psychiatric disorders is often overlooked. Children presenting with symptoms suggestive of a mood disorder, decline in cognition or psychosis deserve a detailed neurological examination and appropriate imaging if indicated, before starting them on antidepressant or neuroleptic medication.

    2010-06-01

    We present a follow-up case report of possible transmission of lymphoma 12 years after deceased-donor renal transplantation from a male donor who was found at autopsy to have had an occult lymphoma. The female recipient underwent prompt transplant nephrectomy. However, 12 years later, she presented with cerebral B cell lymphoma. A donor origin for the cerebral lymphoma was supported by in situ hybridization demonstration of a Y chromosome in the lymphoma. There was a dramatic resolution of the cerebral lesions with tapering of immunosuppression and introduction of rituximab treatment. The finding of a Y chromosome in the cerebral lymphoma does not exclude a host contribution to lymphoma development.

    Primary familial brain calcification (PFBC), also referred to as Idiopathic Basal Ganglia Calcification (IBGC) or “Fahr's disease,” is a clinical condition characterized by symmetric and bilateral calcification of globus pallidus and also basal ganglions, cerebellar nuclei, and other deep cortical structures. It could be accompanied by parathyroid disorder and other metabolic disturbances. The clinical features are dysfunction of the calcified anatomic localization. IBGC most commonly presents with mental damage, convulsion, parkinson-like clinical picture, and neuropsychiatric behavior disorders; however, presentation with impulse control disorder is not a frequent presentation. In the current report, a 43-year-old male patient who has been admitted to psychiatry policlinic with the complaints of aggressive behavior episodes and who has been diagnosed with impulse control disorder and IBGC was evaluated in the light of the literature.

    The purpose of this article is to review the MRI features of monomorphic central nervous system post-transplant lymphoproliferative disorder (CNS PTLD), including diffusion-weighted and susceptibility-weighted sequences before and after treatment and to compare the imaging findings with those of primary central nervous system B cell lymphoma (PCNS BCL). Retrospective review of the brain MRI characteristics in patients with pathology proven monomorphic CNS PTLD and PCNS BCL was performed. In particular, the enhancement, diffusion-weighted, susceptibility-weighted MRI characteristics of the lesions were evaluated. In addition, the diffusion-weighted, susceptibility-weighted MRI features after treatment for CNS PTLD were evaluated. A total of 12 lesions in six patients with CNS PTLD and 12 lesions in nine patients with PCNS BCL were identified on MRI. Among the CNS PTLD lesions with post-contrast images, 80 % demonstrated peripheral enhancement. All of the CNS PTLD lesions contained foci of intratumoral susceptibility signal (ITSS) and the average mean ADC values and ratios were 0.892 × 10(-3) mm(2)/s (standard deviation: 0.082 × 10(-3) mm(2)/s) and 1.19 (standard deviation: 0.15), respectively. On the other hand, 75 % of the PCNS BCL displayed diffuse enhancement, two cases (16.7 %) contained ITSS, and the mean ADC values and ratios were 0.721 × 10(-3) mm(2)/s (standard deviation: 0.093 × 10(-3) mm(2)/s), and 0.99 (standard deviation: 0.17), respectively. Thus, the presence of heterogeneous lesions with ITSS that do not necessarily have as extensive restricted diffusion as PCNS BCL is suggestive of CNS PTLD in the appropriate clinical setting. The preliminary data in this series suggests that diffusion-weighted imaging may serve as a useful biomarker for monitoring treatment response, in which successful treatment of CNS PTLD may result in increased ADC values. In addition, foci of susceptibility effect in CNS PTLD tend to persist or increase over the course of

    Introduction. Substance use disorders (SUDs) are commonly associated with a variety of psychiatric disorders. Community-based studies have found a significant association between SUDs and sexual dysfunction in men, with a possible causal relation in the case of nicotine. Methods. The case records of 105 men presenting to a clinic for patients with psychosexual disorders were reviewed. Men with and without comorbid SUDs were compared in terms of demographic, clinical, and familial variables. Results. 25 of the 105 men (23.8%) had a lifetime diagnosis of SUD, and 19 (18.1%) had a current SUD. The commonest substances involved were nicotine (n = 21, 20%) and alcohol (n = 9, 9.5%). Men with comorbid SUDs were more likely to report a family history of substance dependence, particularly alcoholism. Single men with SUDs were more likely to have a comorbid mood disorder. Conclusion. SUDs, particularly nicotine and alcohol use disorders, are common comorbidities in patients with psychosexual disorders. Identifying and treating these disorders in this population are important aspects of management.

    Full Text Available Obsessive compulsive disorder (OCD is a common psychiatric disorder which is easily recognized. However, sometimes patients of OCD present in such an atypical presentation of symptoms and a pathway to care involving multiple specialities. We report a case of a girl who had consulted several physicians and a urologist for frequent micturition, who was treated as a case of OCD after clarifying the compulsive nature of her symptom. There was significant improvement in her condition following 8 weeks of treatment with 200 mg of Sertraline and behaviour therapy.

    To describe clinical presentations of bipolar disorder in children and adolescents when they were diagnosed. The present study was a retrospective chart review of patients who were diagnosed bipolar disorder when they were under 19 years of age. All subjects, both inpatients and outpatients, received psychiatric treatment at Ramathibodi hospital between January 1998 and May 2008. Forty-nine subjects aged between eight and 18-years-old (mean 15.3 years) were diagnosed as bipolar disorder Thirty-seven percent of patients had cardinal symptoms including elevated mood and/or grandiosity. Being talkative was the most common associated symptom, found in 47% of patients. Psychotic symptoms were found in 39% of patients. Moreover 27% of patients suffered from suicidal idea or had attempted suicide at the time of diagnostic. Although there is very limited information about clinical presentations of bipolar disorder in children and adolescents, especially in Thai population, the author found that only 37% of these patients presented with cardinal symptoms at the time of diagnosis.

    Japanese Ministry of Health, Labour and Welfare shows that the estimated number of all patients with any anxiety disorders is more than ten million, while the number of all depressive patients is about six million. Thus, anxiety disorders are very important in daily clinical situation of psychiatry. Recently, DSM-5 draft posted online (http://www.dsm5.org). Many of the disorders that were previously listed in the anxiety disorders chapter in DSM-IV have been distributed throughout this chapter as well as separate chapters on obsessive-compulsive and related disorders and trauma-and stressor-related disorders. As for panic disorder that was one of the new concepts of psychiatric disorder in DSM-III, there are some changes in the criteria, for instance subcategory according to with/without agoraphobia are discontinued since agoraphobia is proposed to be a codable disorder in DSM-5. In this paper, we will review the history and pathogenesis of panic disorder and the relationships between DSM and ICD, and then discuss the present and future of panic disorder viewed in DSM-5 draft.

    Cocaine, the third mostly commonly used illicit drug in the United States, has a wide range of neuropsychiatric effects, including transient psychotic symptoms. When psychotic symptoms occur within a month of cocaine intoxication or withdrawal, the diagnosis is cocaine-induced psychotic disorder (CIPD). Current evidence suggests those with CIPD are likely to be male, have longer severity and duration of cocaine use, use intravenous cocaine, and have a lower body mass index. Differentiating CIPD from a primary psychotic disorder requires a detailed history of psychotic symptoms in relation to substance use and often a longitudinal assessment. Treatment includes providing a safe environment, managing agitation and psychosis, and addressing the underlying substance use disorder. This review begins with a clinical case and summarizes the literature on CIPD, including clinical presentation, differential diagnosis, mechanism and predictors of illness, and treatment.

    MELAS is commonly associated with peripheral hearing loss. Auditory agnosia is a rare cortical auditory impairment, usually due to bilateral temporal damage. We document, for the first time, auditory agnosia as the presenting hearing disorder in MELAS. A young woman with MELAS (A3243G mtDNA mutation) suffered from acute cortical hearing damage following a single stroke-like episode, in the absence of previous hearing deficits. Audiometric testing showed marked central hearing impairment and very mild sensorineural hearing loss. MRI documented bilateral, acute lesions to superior temporal regions. Neuropsychological tests demonstrated auditory agnosia without aphasia. Our data and a review of published reports show that cortical auditory disorders are relatively frequent in MELAS, probably due to the strikingly high incidence of bilateral and symmetric damage following stroke-like episodes. Acute auditory agnosia can be the presenting hearing deficit in MELAS and, conversely, MELAS should be suspected in young adults with sudden hearing loss.

    Sheehan’s syndrome or Simmond’s disease is a rare endocrine disorder seen in clinical practice. The clinical spectrum is diverse and a high index of suspicion together with a good clinical acumen and proper diagnostic approach helps in early diagnosis and prompt treatment of this endocrinopathy. Sheehan’s syndrome presenting as a major depressive disorder finds less mention in the literature. The patient discussed here is a 45-year-old female who had been on antidepressants and psychiatry follow up for a long time until she presented to our Out Patient Department (OPD), where she was evaluated in detail and diagnosed as a case of Sheehan’s syndrome. The patient is doing well and is on a regular follow-up with us. Further studies are required to demystify the strength of this association in more detail and to elucidate the possible underlying mechanism. PMID:25648343

Iran J Child Neurol. Spring 2015;9(2:53-57.AbstractObjectiveHomocystinuria is an inborn error of amino acid metabolism caused by cystathionine beta-synthase deficiency that affects methionine metabolism. The clinical features are heterogeneous ranging from mental retardation, ectopia lentis, and osteoporosis to vascular events such as deep vein thrombosis,   sagital sinus thrombosis, and myocardial infarction. Cerebral sinovenous thrombosis (CVST is an unusual disorder in children and requires prompt and accurate management. Some causal factors for thedevelopment of CVST differ between children and adults. The majority of cases with CSVT are found to have an underlying cause for thrombosis like dehydration, infections, prothrombotic and hematologic disorders, malignancy and trauma.Although homocystinuria is usually associated with ischemic strokes, CVST as initial clinical presentation of homocystinuria is rare in children.In this article, we presented a 10-year old boy with seizure, hemiparesis, and ataxia due to CSVT caused by homocystinuria.

    This article describes two siblings with infantile Refsum disease (IRD) whose initial presentation was that of malabsorption and mimicked a-beta- or homozygous hypo-beta-lipoproteinemia. Failure to recognize IRD in the first-born child precluded proper genetic counseling and prenatal diagnosis in subsequent pregnancies and also caused considerable delay in diagnosing IRD in the second child. The clinical heterogeneity of peroxisomal disorders constitutes a diagnostic challenge, which demands a high degree of awareness from the part of the clinician. This is particularly the case with IRD, where protracted diarrhea with low serum cholesterol levels appears to be a frequently occurring initial feature during the 1st months of life.

    Full Text Available Background: Adhesive arachnoiditis is a chronic, insidious condition that causes debilitating intractable pain and a range of other neurological problems. Its pathophysiology is not well understood. This manuscript discusses its presentations, which can mimic an acute spinal disorder, its hypothetical pathophysiology, treatment, and its relationship with fibromyalgia. Case Description: The authors present a case of a 47-year-old female who presented with clinical features mimicking an acute spinal disorder but later found to have an adhesive arachnoiditis. She was admitted following a trauma with complaints of back pain and paraplegia. On examination, there was marked tenderness over thoracolumbar spine with lower limbs upper motor neuron weakness. An urgent magnetic resonance imaging (MRI of the spine revealed multiple lesions at her thoracic and lumbar spinal canals, which did not compress the spinal cord. Therefore, conservative management was initiated. Despite on regular therapies, her back and body pain worsened and little improvement in her limbs power was noted. Laminectomy was pursued and found to have spinal cord arachnoiditis. Subsequently, she was operated by other team members for multiple pelvic masses, which later proved to be benign. After gathering all the clinical information obtained at surgery and after taking detailed history inclusive of cognitive functions, diagnosis of an adhesive arachnoiditis syndrome was made. Currently, she is managed by neuropsychologist and pain specialist. Conclusion: This case report highlights the importance of knowing an adhesive arachnoiditis syndrome - a rarely discussed pathology by the neurosurgeon, which discloses a significant relationship between immune and nervous systems.

    Abstract Disorders of sex development (DSD) present in different forms but, in most cases, with visible anomalies of the external genitalia. The diagnosis of DSD can have a vast impact on an individual; in addition to concerns about fertility and a higher risk of neoplasia, it may have severe...... psychosocial impact on the patient. This report presents two apparently healthy cases referred for operation because of unilateral undescended testis. In these two patients, uterine remnants were found during the operation, and underlying DSD conditions were unexpectedly diagnosed. One patient had a 45,X/46,XY...... mosaic karyotype, while the second patient had persistent müllerian duct syndrome, probably due to an anti-müllerian hormone receptor defect. Both conditions are extremely rare, but the findings reinforce that DSD should be considered in patients with cryptorchidism, especially if other clinical signs...

    Autoimmune lymphoproliferative syndrome is frequently caused by mutations in genes involved in the Fas death receptor pathway, but for 20-30% of patients the genetic defect is unknown. We observed that treatment of healthy T cells with interleukin-12 induces upregulation of Fas ligand and Fas ligand-dependent apoptosis. Consistently, interleukin-12 could not induce apoptosis in Fas ligand-deficient T cells from patients with autoimmune lymphoproliferative syndrome. We hypothesized that defects in the interleukin-12 signaling pathway may cause a similar phenotype as that caused by mutations of the Fas ligand gene. To test this, we analyzed 20 patients with autoimmune lymphoproliferative syndrome of unknown cause by whole-exome sequencing. We identified a homozygous nonsense mutation (c.698G>A, p.R212*) in the interleukin-12/interleukin-23 receptor-component IL12RB1 in one of these patients. The mutation led to IL12RB1 protein truncation and loss of cell surface expression. Interleukin-12 and -23 signaling was completely abrogated as demonstrated by deficient STAT4 phosphorylation and interferon γ production. Interleukin-12-mediated expression of membrane-bound and soluble Fas ligand was lacking and basal expression was much lower than in healthy controls. The patient presented with the classical symptoms of autoimmune lymphoproliferative syndrome: chronic non-malignant, non-infectious lymphadenopathy, splenomegaly, hepatomegaly, elevated numbers of double-negative T cells, autoimmune cytopenias, and increased levels of vitamin B12 and interleukin-10. Sanger sequencing and whole-exome sequencing excluded the presence of germline or somatic mutations in genes known to be associated with the autoimmune lymphoproliferative syndrome. Our data suggest that deficient regulation of Fas ligand expression by regulators such as the interleukin-12 signaling pathway may be an alternative cause of autoimmune lymphoproliferative syndrome-like disease.

  13. [Confusing clinical presentations and differential diagnosis of bipolar disorder].

    2004-01-01

    An early recognition of bipolar disorders may have an important impact on the prognosis of this disorder according to different mechanisms. Bipolar disorder is nevertheless not easy to detect, the diagnosis being correctly proposed after, in average more than a couple of Years and three different doctors assessments. A short delay before introducing the relevant treatment should help avoiding inappropriate treatments (prescribing, for example, neuroleptics for long periods, antidepressive drugs each time depressive symptoms occurs, absence of treatment despite mood disorders), with their associated negative impact such as mood-switching, rapid cycling or presence of chronic side-effects stigmates. Furthermore, non-treated mood disorders in bipolar disorder are longer, more stigmatizing and may be associated with an increased risk of suicidal behaviour and mortality. Lastly, compliance, an important factor regarding the long term prognosis of bipolar disorder, should be improved when there is a short delay between correct diagnosis and treatment and onset of the disorder. We therefore propose to review the literature for the different pitfalls involved in the diagnosis of bipolar disorder. Non-bipolar mood-disorders are frequently quoted as one of the alternative diagnosis. Hyperthymic temperament, side-effects of prescribed treatments and organic comorbid disorders may be involved. Bipolar disorders have a sex-ratio closer to 1 (men are thus more frequently of the bipolar type in mood-disorders), with earlier age at onset, and more frequent family history of suicidal attempts and bipolar disorder. Schizo-affective disorders are also a major concern regarding the diagnosis of bipolar disorder. This is explained by flat affects sometimes close to anhedonia, presence of a schizoïd personality in bipolar disorder, persecutive hostility that can be considered to be related to irritability rather than a schizophrenic symptom.

    Full Text Available Dysphagia is a condition in which disruption of the swallowing process interferes with a patient’s ability to eat. This may result in coughing or choking while swallowing, food sticking in the throat, or globus sensation. Eosinophilic esophagitis (EoE is a chronic immune-mediated disease with a varied clinical spectrum of symptoms including dysphagia. Tourette syndrome (TS is an inherited neurological disorder that manifests itself as a series of motor and vocal tics and may include oropharyngeal dysphagia. Dysphagia as a result of TS generally affects female, elderly patients and is not reported in children. While the pathophysiology is relatively unknown, experts believe TS is closely linked to damage or abnormalities in the basal ganglia of the brain. We present this interesting pediatric case of dysphagia due to EoE, which had been previously thought to be related to the patient’s TS.

In this syndrome, the most common neurologic abnormality is transient ischemic attack. This can be easily overlooked if a patient presents with progressive neuropsychiatric disorders, such as depression or dementia. We report two cases of young women, aged 35 and 22 years, presenting with progressive depression and mental decline over a certain period. The neuropsychological diagnoses of the two patients were, respectively, dementia with disinhibition and borderline dementia with depression. Brain magnetic resonance imaging showed multiple old infarcts with encephalomalacia in the former case, and only one cortical hemorrhagic infarction, over the right temporoparietal lobe, observed in the latter case. The outcomes of the two cases were also very different. Progressive neuropsychiatric disorders are increasingly observed in the young; therefore, APS and other autoimmune diseases should be considered during the differential diagnosis. Brain imaging examinations may prevent a delay in the detection of a structural lesion and facilitate the early intervention with good prognosis. Careful investigations by experts from different disciplines are always encouraged in complicated cases.Keywords: autoimmune disease, brain imaging, dementia, depression, cerebrovascular disease

    Full Text Available Acquired hypopigmentary disorders comprise a significant group of disorders that affect Indians and Asians. The pigment disturbance in darker skin individuals can be very distressing to the patient and the family. These disorders cover a wide array of pathologies including infections, autoimmune processes, lymphoproliferative disorders, and sclerosing diseases. Histological diagnosis is particularly important because treatments for these diseases are varied and specific. This review will focus on histopathological diagnosis based on clinicopathological correlation for commonly encountered disorders such as leprosy, vitiligo, lichen sclerosus, pityriasis alba (PA, and pityriasis versicolor (PV. Atypical or uncommon clinical presentation of classic diseases such as hypopigmented mycosis fungoides (HMF and hypopigmented sarcoidosis are also included.

Research indicates that aggression rates may be higher in individuals with ASD compared to those with other developmental disabilities. Aggression is associated with negative outcomes for children with ASD and their caregivers, including decreased quality of life, increased stress levels, and reduced availability of educational and social support. Therapeutic strategies including functional behavioral assessment, reinforcement strategies, and functional communication training may have a significant impact in reducing the frequency and intensity of aggressive behavior in individuals with ASD. Pharmacologic treatments, particularly the use of second-generation antipsychotics, may also be of some benefit in reducing aggression in individuals with ASD. With the ever-increasing rate of ASD diagnosis, development of effective therapeutic and pharmacologic methods for preventing and treating aggression are essential to improving outcomes in this disorder.

    Autoimmune lymphoproliferative syndrome (ALPS) is an inherited disorder associated with defects in apoptosis, characterized by childhood onset of lymphadenopathy, splenomegaly, hyperimmunoglobulinemia, and autoimmune disease. ALPS is most frequently associated with a mutation in the cell death receptor Fas (CD95). Very rarely a mutation in caspase 10 is present. An increase of CD4/CD8 double negative T cells in the peripheral blood and lymph nodes is a feature characteristic of ALPS. Additionally, histiocytic proliferations resembling sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) were reported recently in patients with ALPS. In the rare cases with a caspase 10 mutation an accumulation of dendritic cells in lymphoid organs was noted. We describe a different, sarcoidosislike, histiocytic infiltration of lymph nodes that persisted for years in a girl, that was initially supposed to suffer from sarcoidosis, but was eventually diagnosed as ALPS, associated with a missense mutation in the intracellular death domain of Fas. This sarcoidosislike histologic picture extends the spectrum of histiocytic lymph node alterations observed in ALPS and alerts of a potential diagnostic pitfall.

DTD describes the human health ailments that accompany the implementation of disruptive technologies. Elevator sickness, railway spine, and bicycle face are representative examples. Though the underlying causative disruptive technologies may differ, many neurologic symptoms (headache, dizziness, weakness) are common to multiple DTDs. Born of technology-driven societal change, DTDs manifest as a complex interplay between biological and psychological symptoms. © 2017 American Academy of Neurology.

    Some of the most common complicating factors for clinicians treating a person with obsessive-compulsive disorder include suicidal obsessions, dangerous compulsions, overvalued ideation, and low motivation. When a patient reports suicidal thoughts, clinicians must assess whether these thoughts are ego-syntonic or ego-dystonic because patients with ego-dystonic suicidal obsessions have less risk of imminent harm. For individuals whose compulsions are dangerous, clinicians must determine the best type of treatment facility to reduce the risk of harm. Patients with overvalued ideation may require unique interviewing approaches and the support of family members. Finally, clinicians should assess for health problems that can cause low energy and fatigue and consider motivational interviewing and additional therapies for patients who have low motivation to continue treatment.

    Over the past 20 years, the evidence regarding pediatric bipolar disorder (BP) has increased substantially. As a result, recent concerns have focused primarily on prevalence and differential diagnosis. Selective review of the literature. BP as defined by rigorously applying diagnostic criteria has been observed among children and especially adolescents in numerous countries. In contrast to increasing diagnoses in clinical settings, prevalence in epidemiologic studies has not recently changed. BPspectrum conditions among youth are highly impairing and confer high risk for conversion to BP-I and BP-II. Compared to adults, youth with BP have more mixed symptoms, more changes in mood polarity, are more often symptomatic and seem to have worse prognosis. The course, clinical characteristics, and comorbidities of BP among children and adolescents are in many ways otherwise similar to those of adults with BP. Nonetheless, many youth with BP receive no treatment and most do not receive BP-specific treatment. Despite increased evidence supporting the validity of pediatric BP, discrepancies between clinical and epidemiologic findings suggest that diagnostic misapplication may be common. Simultaneously, low rates of treatment of youth with BP suggest that withholding of BP diagnoses may also be common. Clinicians should apply diagnostic criteria rigorously in order to optimize diagnostic accuracy and ensure appropriate treatment.

    Previous studies have shown that bone growth acceleration can occur in many animal species after periosteal resection (removal of a strip of periosteum) with minimum morbidity. This has numerous clinical applications, including treatment of limb length differences. Here we use Second Harmonic Generation (SHG) imaging microscopy to evaluate changes in collagen architecture reflective of the different strains the periosteum may encounter during bone growth. Specifically, we image rabbit tibial periosteum strips at -20%, 0%, 5%, and 10% strains. We first quantify these changes using the SHG creation ratio (Forward/Backward) or the initially emitted SHG directionality to provide information on the fibril level of assembly. The in situ (i.e. physiological) strain had the highest creation ratio compared to the non-in situ strains of -20%, 5%, and 10%, which were shown to be significantly different via RCBD statistical analysis. These trends are consistent with SHG phasematching considerations, where more organized fibrils/fibers result in primarily forward emitted components, which here is the physiological strain. We further use the relative SHG conversion efficiency to assess the tissue structure under strain, where this results from the combination of collagen concentration and organization. The 0% strain SHG conversion efficiency was significantly higher than all other strains, where this is expected as the fibers have the highest local density and organization, and is consistent with the emission directionality results. Importantly, due to the underlying physical process, the label-free SHG imaging modality can non-invasively monitor the effect of treatments for bone growth and other orthopedic disorders.

    The principal findings revealed by our /sup 18/F-fluoro-2-deoxyglucose (/sup 18/FDG) and /sup 15/O-oxygen study were reviewed in the former part of this paper. (1) The effect of surgical severing of fiber connections on the terminal gray matter was clearly demonstrated in the following examples. A patient with the injured left optic radiation showed a markedly decreased /sup 18/FDG uptake in the ipsilateral primary visual cortex. The extent of the decrease was larger in the secondary visual cortex (--60%). The patient with bilateral frontal leukotomy (lobotomy) showed about 30% decrease of oxygen accumulation not only in the frontal cortex but in the anterior half of the temporal cortex. (2) The effect of electrical stimulation of the left median nerve can be detected as an increased /sup 18/FDG accumulation in the corresponding sensory and motor areas in the right precentral and postcentral cortices. The slight to moderate increase in the right striatal region was thought to be related to the muscle movement caused by the stimulation. (3) The neuro-degenerative disorders such as Huntington's chorea and Parkinsonism could be diagnosed by demonstrating the decrease of /sup 18/FDG in the degenerating focus or the increase in the secondarily affected area. An example was provided by a case of Huntington's chorea patient who showed a markedly decreased /sup 18/FDG uptake in the striatal region in spite that /sup 13/N-ammonia visualized this area. (4) Dementia gives another field where the /sup 18/FDG and /sup 15/O/sub 2/ studies are demonstrated to be quite useful. (5) The /sup 18/FDG studies on the intrinsic psychoses are also reviewed. But consistent results seemed to be very difficult in this area by using labeled sugars and oxygens which are nonspecific gray matter imagers. Therefore, new tracers and new techniques in positron emission tomography are briefly described in the latter part of this paper.

    Role of metabolism by intestinal bacteria in arbutin-induced immunotoxicity was investigated in splenocyte cultures. Following an incubation of arbutin with 5 different intestinal bacteria for 24 hr, its aglycone hydroquinone could be produced and detected in the bacterial culture media with different amounts. Toxic effects of activated arbutin by intestinal bacteria on lymphoproliferative response were tested in splenocyte cultures from normal mice. Lipopolysaccharide and concanavalin A were used as mitogens for B- and T-cells, respectively. When bacteria cultured medium with arbutin was treated into the splenocytes for 3 days, the medium cultured with bacteria producing large amounts of hydroquinone induced suppression of lymphoproliferative responses, indicating that metabolic activation by intestinal bacteria might be required in arbutin-induced toxicity. The results indicated that the present testing system might be applied for determining the possible role of metabolism by intestinal bacteria in certain chemical-induced immunotoxicity in animal cell cultures.

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of T cell dysregulation caused by defective Fas-mediated apoptosis. Patients with ALPS can develop a myriad of clinical manifestations including lymphadenopathy, hepatosplenomegaly, autoimmunity and increased rates of malignancy. ALPS may be more common that originally thought, and testing for ALPS should be considered in patients with unexplained lymphadenopathy, hepatosplenomegaly, and/or autoimmunity. As the pathophysiology of ALPS is better characterized, a number of targeted therapies are in preclinical development and clinical trials with promising early results. This review describes the clinical and laboratory manifestations found in ALPS patients, as well as the molecular basis for the disease and new advances in treatment.

    Full Text Available The paper reported on a case of severe myoclonic epilepsy of infancy (SMEI associated with a probable autoimmune lymphoproliferative syndrome variant (Dianzani autoimmune lymphoproliferative disease (DALD. A male patient with typical features of SMEI and a SCN1A gene variant presented in the first year of life with multiple lymph nodes, palpable liver at 2 cm from the costal margin, neutropenia, dysgammaglobulinemia, relative and sometimes absolute lymphocytosis. Subsequently the patient presented with constantly raised IgA in serum and positive antinuclear and thyroid antimicrosomal antibodies. The diagnosis of probable autoimmune lymphoproliferative syndrome was made; arthritis, skin and throat blisters, which appeared subsequently led to the diagnosis of linear IgA disease. On the basis of these unique associations, the Authors hypothesized that autoimmunity may be partly responsible of the severe epileptic symptomatology, perhaps mediated by autoantibodies against sodium channels or by accompanying cytotoxic T-lymphocytes. Corticosteroid treatment ameliorated the epilepsy and laboratory tests. Future studies will be necessary to evaluate the relevance of autoimmunity in SMEI.

    2011-03-01

    Numerous somatic and psychopathological disorders occur parallel with autism spectrum disorders. It is presently being discussed whether other co-occurring psychopathological symptoms should constitute a categorical comorbid disorder on their own right and be diagnosed as such; or whether they should be understood as part of the autistic disorder itself. Based on the situation with attention deficit/hyperactivity disorder (ADHD), the current state of research and our own research results are used as examples to demonstrate which prerequisites must be fulfilled for a comorbid disorder. Furthermore, based on neurobiological findings from the areas of molecular biology, neuropsychology, and imaging we show which requirements emerge for the aetiology, early detection, pharmacological and psychotherapeutic treatment, course of illness, and the categorical classification approach.

    Post-transplant lymphoproliferative disorder (PTLD) is an increasingly recognized condition as the number of solid organ and bone marrow transplant recipients increases. It can be a life threatening fulminant disorder and affects approximately 8% of solid organ transplant recipients. Epstein-Barr virus (EBV) is closely involved in the pathogenesis of PTLD and the majority of PTLD cases arise in response to primary infection with EBV or to re-activation of previously acquired EBV. The principal risk factors underlying the development of PTLD are the degree of overall immunosuppression and EBV serostatus of the recipient. The most commonly used pathologic classification of PTLD is the World Health Organization classification, which divides PTLD into three categories: early lesions, polymorphic PTLD, and monomorphic PTLD. Early lesions are characterized by reactive plasmacytic hyperplasia. Polymorphic PTLD may be either polyclonal or monoclonal and is characterized by destruction of the underlying lymphoid architecture, necrosis, and nuclear atypia. In monomorphic PTLD, the majority of cases (>80%) arise from B cells, similar to non-Hodgkin's lymphoma in immunocompetent hosts. The most common subtype is diffuse large B-cell lymphoma, but Burkitt's/Burkitt's-like lymphoma and plasma cell myeloma are also seen. Rarely T-cell variants occur, which include peripheral T-cell lymphomas and, rarely, other uncommon types, including gamma/delta T-cell lymphoma and T-natural killer (NK) cell varieties. Hodgkin's disease-like lymphoma is very unusual. An accurate diagnosis of PTLD requires a high index of suspicion, since the disorder may present subtly and/or extranodally. Radiologic evidence of a mass or the presence of elevated serum markers (such as increased LDH levels) are suggestive of PTLD, with positive finding on ultrasonography, computed tomography, magnetic resonance and/or positron emission tomography scanning (possibly indicating metabolically active areas) also

    Young males with eating disorders are a neglected study population in eating disorders. The aim of this study was to provide knowledge about the clinical presentation of eating disorders in young males. The data source was the Helping to Outline Paediatric Eating Disorders (HOPE) Project (N ~ 1000), a prospective, ongoing registry comprising consecutive paediatric (eating disorder referrals. Young males with DSM-5 eating disorders (n = 53) were compared with young females with eating disorders (n = 704). There was no significant difference in the prevalence of diagnosis of bulimia nervosa (2 % vs 11 %, p = 0.26) among sexes. Males had comparable duration of illness (9 months; p = 0.28) and a significantly earlier age of onset (M = 12 years; p eating disorders (40 % vs 22 % for females, p = 0.004). Driven exercise to control weight and shape was common and comparable in prevalence among males and females (51 % vs 47 %, p = 0.79) and males were less likely to present with self-induced vomiting (OR = 0.23, 95 % CI: 0.09, 0.59). Boys with eating disorders are an understudied group with similarities and differences in clinical presentation from girls with eating disorders. Parents and physicians are encouraged to consider changes in weight, disturbed vital signs, and driven, frequent exercise for the purposes of controlling weight or shape, as possible signs of eating disorders among male children. Diagnostic classification, assessment instruments, conceptualisation, and treatment methods need to be refined to improve application to young males.

    Full Text Available Cobalamin is an important nutrient. It is not synthesized in human body and supplied only in nonvegetarian diet. Its deficiency reported with range of psychiatric disorders. Only four pediatric cases have been reported as psychiatric disorders. Authors report a case of dietary deficiency of cobalamin presenting solely as schizoaffective disorder without hematological/neurological manifestations. Early diagnosis and treatment of cobalamin deficiency is an opportunity to reverse pathophysiology. This case highlights the importance of diet history and serum cobalamin level in atypical psychiatric presentations.

    Generalized anxiety disorder (GAD) is a prevalent and disabling disorder characterised by persistent worrying, anxiety symptoms, and tension. General practitioners and mental healthcare professionals frequently misdiagnose the presenting symptoms. This article addresses the clinical presentation of GAD and provides guidelines for discriminating GAD from other disorders, based on theoretical considerations and clinical experience. Debate relating to the validity of the definition of GAD is discussed, and suggestions are made for improving the criteria for GAD, which may guide future versions of classification systems such as the Diagnostic and Statistical Manual.

    The phenotype and genotype of antisocial behavior among females are different from those among males. Previous studies have documented structural brain alterations in males with antisocial behavior, yet little is known about the neural correlates of female antisocial behavior. The present study examined young women who had presented conduct disorder (CDW) prior to age 15 to determine whether brain abnormalities are present in adulthood and whether the observed abnormalities are associated with comorbid disorders or maltreatment that typically characterize this population. Using magnetic resonance imaging and voxel-based morphometry, we compared gray matter volumes (GMV) of 31 women who presented CD by midadolescence and 25 healthy women (HW), age, on average, 23 years. Participants completed structured, validated interviews to diagnose mental disorders, and validated questionnaires to document physical and sexual abuse. Relative to HW, CDW presented increased GMV in the left superior temporal gyrus that was associated with past alcohol and drug dependence, current use of alcohol and drugs, and current anxiety and depression symptoms and maltreatment. Additionally, CDW displayed reduced GMV in lingual gyrus, hippocampus, and anterior cingulate cortex that was associated with past comorbid disorders, current alcohol and drugs use, current anxiety and depression symptoms, and maltreatment. The CDW also presented reduced total GMV that was associated with past comorbid disorders and current anxiety/depression symptoms. Alterations of brain structure were observed among young adult females with prior CD, relative to HW, all of which were associated with internalizing and externalizing disorders and maltreatment that typically accompany CD.

    Background. Creutzfeldt-Jakob disease is a rare disorder of the central nervous system. Its initial diagnosis may be obscured by its variable presentation. This case report illustrates the complexity of diagnosing this disease early in the clinical course, especially when the initial symptoms may be psychiatric. It offers a brief review of the literature and reinforces a role for consultation psychiatry services. Methods. PUBMED/MEDLINE was searched using the terms "Creutzfeldt-Jakob disease", "psychiatric symptoms", "conversion disorder", "somatic symptom disorder", "functional movement disorder", and "functional neurologic disorder". Case. The patient was a 64-year-old woman with no prior psychiatric history who was initially diagnosed with conversion disorder and unspecified anxiety disorder but soon thereafter was discovered to have Creutzfeldt-Jakob disease. Discussion. This case highlights the central role of psychiatric symptoms in early presentations of Creutzfeldt-Jakob disease. Still, few other cases in the literature report functional neurological symptoms as an initial sign. The consultation psychiatrist must remain alert to changing clinical symptoms, especially with uncharacteristic disease presentations.

    Neuromyelitis optica is an autoimmune disorder characterized by optic neuritis, transverse myelitis, and aquaporin-4 autoantibodies. The term "neuromyelitis optica spectrum disorder" refers neuromyelitis optica features occurring in association with other systemic rheumatologic conditions. We present a case of a 51-year-old woman with long-standing systemic sclerosis who developed transverse myelitis in association with the presence aquaporin-4 autoantibodies. This is the first report case of neuromyelitis optica spectrum disorder associated with systemic sclerosis. Given that patients with neuromyelitis optica spectrum disorder with aquaporin-4 autoantibodies have a high risk for clinical relapse, this report underscores the need for recognition of this disorder in patients with systemic sclerosis and neurological dysfunction.

    Waldenström macroglobulinemia (WM) is a low-grade incurable immunoglobulin M+ (IgM+) lymphoplasmacytic lymphoma for which a genetically engineered mouse model of de novo tumor development is lacking. On the basis of evidence that the pro-inflammatory cytokine, interleukin 6 (IL6), and the survival-enhancing oncoprotein, B cell leukemia 2 (BCL2), have critical roles in the natural history of WM, we hypothesized that the enforced expression of IL6 and BCL2 in mice unable to perform immunoglobulin class switch recombination may result in a lymphoproliferative disease that mimics WM. To evaluate this possibility, we generated compound transgenic BALB/c mice that harbored the human BCL2 and IL6 transgenes, EμSV-BCL2-22 and H2-Ld-hIL6, on the genetic background of activation-induced cytidine deaminase (AID) deficiency. We designated these mice BCL2+IL6+AID− and found that they developed—with full genetic penetrance (100% incidence) and suitably short latency (93 days median survival)—a severe IgM+ lymphoproliferative disorder that recapitulated important features of human WM. However, the BCL2+IL6+AID− model also exhibited shortcomings, such as low serum IgM levels and histopathological changes not seen in patients with WM, collectively indicating that further refinements of the model are required to achieve better correlations with disease characteristics of WM.

    Objective To explore the therapeutic effect of hematopoietic stem cell transplantation for treatment of EBV-associated T/Natural Killer-cell Lymphoproliferative disorder in children. Methods A 13.5-year old boy .diagnosed with EBV-associated T/natural killer-cell lymphoproliferative disorder (EBV-T/NK-LPD) , received HLA-matched sibling PBSCT from his younger sister, as his disease was persistent after treatment with anti-virus drugs, EBV-CTL,interleukin-2 and chemotherapy. The conditioning regimen was TBI/CY+VP16 (total-body irradiation, 12 Gy in 8 fractions, -8d -5d; cyclophosphamide, 60mg/kgxtwo doses, -3d ~ -2d; a single dose of etoposide, 30mg/kg, -4d). The infused PBSCs contained 6.34×107kg nucleated cells and 3.80×106/ kg CD34 positive cells. GVHD prophylaxis consisted of cyclosporine A (CsA) and a short course of methotrexate (sMTX). Results The hematologic recovery was favorable. The patient achieved neutrophil engraftment at day +16;platelet engraftment was achieved at day +37;his hemo-gram completely recovered at day +60. The patient had no severe complications, such as fatal infections, hemorrhagic cystitis, veno-occlusive disease (VOD), interstitial pneumonia (IP),eytomegalovirus (CMV) infection, et al. He developed cutaneous Grade II acute graft-versus-host disease (GVHD) at day +62. The EBV-DNA was 1.2×105 copies/ml before transplant,and changed-over to negative at day +14; after this, the EBV-DNA was monitored weekly,persistently negative. After transplantation, the patient' s jaundice disappeared, and the liver function normalized. Rechecking type-B ultrasonic on the cervix and the abdomen, there was no signs of lymphadenectasis at pars cervicalis, hepatomega- ly , or splenomegaly; the previous lymphadenectasis at porta hepatic and aside abdominal aorta disappeared. Computed tomography scan at thorax dis- played no lymphadenectasis at portopulmonary, the mediastinum was normal. Up to now, and the patient has been followed up for 18 months after

    Copper is a trace element that is required for cellular respiration, neurotransmitter biosynthesis, pigment formation, antioxidant defense, peptide amidation, and formation of connective tissue. Abnormalities of copper metabolism have been linked with neurologic disorders that affect movement, such as Wilson disease and Menkes disease; however, the diagnosis of non-Wilson, non-Menkes-type copper-metabolism disorders has been more elusive, especially in cases with atypical characteristics. We present here the case of an adolescent with a novel presentation of copper-metabolism disorder who exhibited acute severe hemilingual dyskinesia and prominent tics, with ballismus of the upper limbs, but had normal brain and spinal MRI results and did not show any signs of dysarthria or dysphagia. His serum copper and ceruloplasmin levels were low, but his urinary copper level was elevated after penicillamine challenge. We conclude that copper-metabolism disorders should be included in the differential diagnosis for movement disorders, even in cases with highly unusual presentations, because many of them are treatable. Moreover, a connection between copper-metabolism disorders and tics is presented, to our knowledge, for the first time in humans; further investigation is needed to better establish this connection and understand its underlying pathophysiology.

    2016-01-01

    Phenylketonuria is one of the most prevalent autosomal recessive hereditary disorders in Turkey. If untreated, it results in severe brain damage and can also be associated with autism in certain patients. We present a three-year old boy who exhibited the symptoms of autism and was subsequently diagnosed with phenylketonuria. This case illustrates that because the majority of autism cases are idiopathic, an occasional patient with a metabolic disorder might be overlooked especially in the era of newborn screening. We also discuss the possible pathogenetic processes leading to autistic symptoms in phenylketonuria, and wish to draw attention to the possibility of cases missed in the screening program because of less than 100% coverage or insufficient food intake before blood sampling. Clinicians should keep in mind the possibility of treatable disorders in children with autism even when such disorders appear unlikely.

    Full Text Available Background. Huntington’s disease (HD is rare. It usually starts with choreatic movements and cognitive impairment, progressing to dementia. A case report revealing diagnostic difficulties in a patient with HD, which began as psychotic disorder is presented. Patient was treated for almost five years in psychiatric outpatients’ service and psychiatric hospital due to a treatment-resistant psychotic disorder. Choreatic movements emerged during the fourth year of the treatment and were misdiagnosed as tardive dyskinesia. Prominent deterioration of cognitive functions demanded further diagnostics. With genetic tests HD was diagnosed.Conclusions. The start of HD with psychotic disorder is less common. In patients with treatment-resistant psychoses other somatic disorders should be considered.

    2013-01-01

    Objective: Body dysmorphic disorder (BDD) is a relatively common psychiatric disorder characterized by preoccupations with perceived defects in physical appearance. This review aimed to explore epidemiology, clinical features, comorbidities, and treatment options for BDD in different clinical settings. Data Source and Study Selection: A search of the literature from 1970 to 2011 was performed using the MEDLINE search engine. English-language articles, with no restriction regarding the type of articles, were identified using the search terms body dysmorphic disorder, body dysmorphic disorder clinical settings, body dysmorphic disorder treatment, and body dysmorphic disorder & psychodermatology. Results: BDD occurs in 0.7% to 2.4% of community samples and 13% of psychiatric inpatients. Etiology is multifactorial, with recent findings indicating deficits in visual information processing. There is considerable overlap between BDD and obsessive-compulsive disorder (OCD) in symptom etiology and response to treatment, which has led to suggestions that BDD can be classified with anxiety disorders and OCD. A recent finding indicated genetic overlap between BDD and OCD. Over 60% of patients with BDD had a lifetime anxiety disorder, and 38% had social phobia, which tends to predate the onset of BDD. Studies reported a high level of comorbidity with depression and social phobia occurring in > 70% of patients with BDD. Individuals with BDD present frequently to dermatologists (about 9%–14% of dermatologic patients have BDD). BDD co-occurs with pathological skin picking in 26%–45% of cases. BDD currently has 2 variants: delusional and nondelusional, and both variants respond similarly to serotonin reuptake inhibitors (SRIs), which may have effect on obsessive thoughts and rituals. Cognitive-behavioral therapy has the best established treatment results. Conclusions: A considerable overlap exists between BDD and other psychiatric disorders such as OCD, anxiety, and delusional

    Neuromyelitis Optica Spectrum Disorder (NMOSD) is a rare systemic autoimmune disease which is sometimes found in association with other autoimmune disorders including Sjogren's syndrome. Neurological manifestations occur in 20% to 25% of diagnosed cases of Sjögren's syndrome; however, less than 5% of patients with Sjögren's syndrome have neurological manifestations as the initial presenting feature of Sjögren's syndrome. We report the case of an elderly female with longitudinal myelitis as a presenting feature who had positive antibody to aquaporin-4 (NMO-IgG) and Sjögren's syndrome.

    Autoimmune lymphoproliferative syndrome (ALPS) is a rare disease caused by defective lymphocyte apoptosis and is characterized by non-malignant lymphoproliferation, hepatosplenomegaly, autoimmune manifestations and increased risk of both Hodgkin's and non-Hodgkin's lymphoma. Most forms of the disease are due to germ line mutations of the FAS gene and manifest during the first years of life with fluctuating lymphadenopathies, hemolysis, immune thrombocytopenia. During the second decade of life disease manifestations improve spontaneously but autoimmune problems still occur and there is an increased risk of lymphoproliferative malignancy. We describe a typical case of ALPS in a now 44 year old man, followed since the age of 2 for disease manifestations that were unclear at the beginning.

    Anti-NMDA-receptor encephalitis is a severe, treatable and potentially reversible disorder presenting with memory deficits, psychiatric symptoms and seizures. Initially described in young patients with ovarian teratoma, the disease is meanwhile increasingly recognized also in women without tumours, in men and in children. The presence of anti-glutamate receptor (type NMDA) autoantibodies in serum or cerebrospinal fluid is specific for this novel and widely underdiagnosed disorder. Early recognition is crucial since prognosis largely depends on adequate immunotherapy and, in paraneoplastic cases, complete tumour removal. Indirect immunofluorescence using NMDA-type glutamate receptors recombinantly expressed in human cells is a highly competent method for diagnosing anti-NMDA-receptor encephalitis.

    Post-transplantation lymphoproliferative disorders (PTLDs) are a heterogeneous group of diseases that represent serious complications following immunosuppressive therapy for solid organ or hematopoietic-cell recipients. In contrast to B-cell PTLD, T-cell PTLD is less frequent and is not usually associated with Epstein Barr Virus infection. Moreover, to our knowledge, isolated T-cell PTLD involving the breast is extremely rare and this condition has never been reported previously in the literature. Herein, we report a rare case of isolated T-cell PTLD of the breast that occurred after a patient had been treated for allogeneic peripheral blood stem cell transplantation due to acute myeloblastic leukemia.

    Skin of color, also known as ethnic skin, is described as skin of individuals of African, Asian, Hispanic, Native-American, Middle Eastern, and Pacific Island backgrounds. Differences in hair morphology, hair grooming, cultural practices, and susceptibility to keloid scarring exist within these populations and have been implicated in hair, scalp, and skin disorders. Acne keloidalis (AK), central centrifugal cicatricial alopecia (CCCA), dissecting cellulitis of the scalp (DCS), pseudofolliculitis barbae (PFB), traction alopecia (TA), and keloids are the most prevalent follicular and scarring disorders in skin of color. They have been associated with disfigurement, permanent hair loss, emotional distress, and decreased quality of life. Hair grooming practices, such as the use of chemical relaxers, heat straightening, and tight braiding and weaving can cause scalp irritation and follicular damage and are linked to the pathogenesis of some of these conditions. Consequently, patient education and behavior modifications are integral to the prevention and management of these disorders. Scarring disorders are also of concern in ethnic populations. Keloid scarring is more prevalent in individuals of African, Asian, and Hispanic descent. The scarring alopecia CCCA is almost exclusively seen in patients of African descent. Therapeutic regimens such as intralesional corticosteroids, surgical excision, and laser therapy can be effective for these follicular and scarring disorders, but carry a risk of dyspigmentation and keloid scarring. Ethnic skin and hair may present unique challenges to the clinician, and knowledge of these differences is essential to providing quality care.

    Full Text Available Wilson′s disease (WD is a genetic neurodegenerative disorder; it exhibits wide heterogeneity in symptoms and usually presents with liver disease and/ or neuropsychiatric manifestations. The common neurological manifestations observed are dysarthria, gait disturbance, dystonia, rigidity, tremor, dysphagia and chorea. The frequent psychiatric manifestations reported are personality and mood changes, depression, phobias, cognitive impairment, psychosis, anxiety, compulsive and impulsive behavior. Isolated obsessive-compulsive disorder (OCD is a rare presentation of WD. Reported herein is a case of a 17-year-old boy with isolated OCD. He presented to the psychiatrist with symptoms of contamination obsessions and washing compulsions, along with compulsion of repeated feet tapping, and was treated with adequate doses of fluoxetine for 6 months but did not improve. Later on, he was diagnosed as a case of WD and showed improvement with chelating and behavior therapy. This implies the importance of the occurrence of isolated psychological symptoms in WD.

    2017-01-17

    BACKGROUND Postoperative conversion disorder is rare and has been reported. The diagnosis is usually made after all major organic causes have been ruled out. CASE REPORT We describe a case of a 13-year-old female who presented in the post-anesthesia care unit with acute-onset inspiratory stridor and unresponsiveness to verbal or painful stimuli after receiving a general anesthetic for upper endoscopy. Later in the post-anesthesia care unit, she presented with acute-onset right hemiplegia and sensory loss. She was first evaluated for causes of her stridor and unresponsiveness. The evaluation revealed paradoxical vocal cord movement, and all laboratory test values were normal. For her hemiplegia and sensory loss, she was evaluated for stroke with head MRI and CT scans, which were normal. CONCLUSIONS After extensive workup and consideration of multiple etiologies for her presenting signs and symptoms, the most likely diagnosis was conversion disorder.

    To describe differences between adolescents and adults in clinical presentation of eating disorders. Data from the charts of 622 female patients treated for an eating disorder in a division of adolescent medicine between 1980 and 1994 were coded and computerized. General categories included demographic and family factors, weight loss and weight changes, eating-related behaviors, diagnosis and severity, and treatment issues. Differences between the 438 patients who were aged 9-19 years (adolescents) and 184 patients who were aged 20-46 years (adults) were analyzed. Adolescents were more likely than adults (p or = 3 lb/month, lower original and maximum weights, and history of fasting and elimination of junk food from their diets. Adults were more likely than adolescents (p 1 year of weight loss, greater total weight loss, history of binge eating and laxative use, history of diuretic and ipecac use, diagnosis of bulimia nervosa, and prior use of psychiatric medications. Adolescents and adults did not differ (p >.05) in parents' occupational level; height, weight, and percent ideal body weight at presentation; original percent ideal body weight; use of diet pills, elimination of meat and use of a low-fat diet; daily calorie intake; prior eating disorder hospitalizations; and hospitalization during the course of treatment. The findings in this study document and confirm that there are important differences between adolescents and adults that must be taken into account in the evaluation and treatment of patients with eating disorders.

    Alcohol is one of the most commonly used legal psychoactive substances, and its use often coexists with mental health disorders. This study explores the relationships between alcohol use and some common mental health disorders. Admissions to all New South Wales (NSW) hospitals were analyzed. The data were extracted from the NSW Department of Health Inpatient Statistics Data Collection for the period 1 July 2006 to 30 June 2007. Readmissions within 28 days were excluded. Data extraction and analyses were performed by using the SAS program. Chi-square tests and odds ratio were used to measure the association. Of the 1.8 million admissions, associations between alcohol use disorders and mental health disorders were strong (odds ratio 7.8 to 10.7, P alcohol had at least 1 identifiable mental disorder. Higher comorbidity rates were observed for females (39.6%) and for those aged between 30 and 49 years. The most common mental disorders were anxiety disorders, bipolar affective disorders, major depressive disorders, personality disorders, schizophrenia, and severe stress disorders. Comorbidity with one of these mental disorders ranged from 1% to 17.6%, with significant associations (odds ratio 5.6 to 14.1). The average length of stay (ALOS) for alcohol use disorders were 6.4 days and the ALOS for the most common mental health admissions was 11.2 days. This study provides detailed information about the association between alcohol use and mental health disorders and extends our understanding of comorbidity presentations in inpatient admissions.

    Full Text Available Metabolic disorders, including type 2 diabetes (T2DM and cardiovascular disease (CVD, present an increasing public health concern and can significantly undermine an individual’s quality of life. The relative risk of CVD, the primary cause of death in T2DM patients, is two to four times higher in people with T2DM compared with those who are non-diabetic. The prevalence of metabolic disorders has been associated with dynamic changes in dietary macronutrient intake and lifestyle changes over recent decades. Recently, the scientific community has considered alteration in gut microbiota composition to constitute one of the most probable factors in the development of metabolic disorders. The altered gut microbiota composition is strongly conducive to increased adiposity, β-cell dysfunction, metabolic endotoxemia, systemic inflammation, and oxidative stress. Probiotics and prebiotics can ameliorate T2DM and CVD through improvement of gut microbiota, which in turn leads to insulin-signaling stimulation and cholesterol-lowering effects. We analyze the currently available data to ascertain further potential benefits and limitations of probiotics and prebiotics in the treatment of metabolic disorders, including T2DM, CVD, and other disease (obesity. The current paper explores the relevant contemporary scientific literature to assist in the derivation of a general perspective of this broad area.

    Nonconvulsive status epilepticus can be confused with psychiatric disorders. Inappropriate drug treatment can represent a precipitating factor. We describe two patients with idiopathic generalized epilepsy in whom nonconvulsive status epilepticus, aggravated by carbamazepine, was misdiagnosed as psychiatric disorder. A 14-year-old girl experienced a tonic-clonic seizure at age 12 years preceded by monthly episodes of confusion with awkward behavior since age 9 years. She was treated with carbamazepine, and the episodes of confusion became more frequent, leading to a diagnosis of dissociative disorder. An electroencephalogram during one of these episodes revealed nonconvulsive status epilepticus. Substitution of carbamazepine with valproic acid controlled the episodes of status epilepticus. A 23-year-old woman presented at age 16 years with a tonic-clonic seizure. Since early adolescence, she had had episodes of depressive mood, worsening of school performances, and facial tics. Carbamazepine treatment caused worsening of the depressive episodes and facial tics. An electroencephalogram during a typical episode revealed nonconvulsive status epilepticus. Carbamazepine substitution with valproate led to seizure freedom and behavioral improvement. Nonconvulsive status epilepticus should be suspected and searched for in patients with epileptic seizures and ictal or fluctuating behavioral disorders.

The highly varied morbidity indicates that the affective symptoms in CADASIL have not been cataloged systematically, leading to ineffective treatment, affecting the patients’ quality of life, and possibly resulting in suicide. We present a case of CADASIL with bipolar II disorder as the first manifestation. A middle-aged female reported recurrent depressive episodes and appeared treatment resistant to adequate dosages and durations of antidepressants. Following a structured psychiatric interview and neuropsychological assessment, a past episode of hypomania was identified. Added treatment with sodium valproate alleviated most symptoms. Considering late-onset bipolar disorder with unexplained decline in cognition, a medical history of migraine, and a suspected family history of stroke, further cranial magnetic resonance imaging scan was performed and revealed severe leukoencephalopathy, prompting further investigation. The diagnosis was revised to CADASIL after Arg587Cys NOTCH3 mutation was confirmed. This case highlights the evolving process of affective disorder diagnosis and underlying organic etiologies. Based on the overlap of white matter hyperintensities, NOTCH3 mutation, and valproate therapy in bipolar disorder and CADASIL, bipolar II depression may be a poorly recognized manifestation of CADASIL.

    Long QT syndrome (LQTS) is described as the development of sudden syncope attacks or death as a result of ventricular tachycardia (VT) episodes that might be observed as elongated QT interval in electrocardiography (ECG). Implantable Cardioverter Defibrillator (ICD) is recommended as first-line treatment for the condition in guidelines. We aimed to present an adolescent recently diagnosed with Bipolar Disorder (BD) who had LQTS that was treated with ICD, discussing her follow up and treatment along with relevant literature. Psychiatric assessment of the case that applied to our child psychiatry unit due to manic symptoms were carried out by using Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) criteria. Symptom severity was monitored via Young Mania Rating Scale scores (YMRSS). The case met criteria for Bipolar Disorder Type I (BD-I). She had improvement in her mood symptoms with treatment regimen as risperidone 3 mg/day, valproate 1000 mg/day and lorazepam 1 mg/dayi after her 2-week follow up as well as no reported ICD activity, reflecting fine cardiac functions and rhythm. LQTS is a serious health issue for children and adolescents diagnosed with BD. This condition should be kept in mind especially in cases where familial risk factors are present and precautions need to be maintained upon required assessments. These cases need to be closely monitored due to risk factors related to both BD and LQTS, in a multidisciplinary fashion, involving both psychiatry and cardiology divisions.

    We assessed anxiety consistent (i.e., "traditional") and inconsistent (i.e., "atypical") with diagnostic and statistical manual (DSM) definitions in autism spectrum disorder (ASD). Differential relationships between traditional anxiety, atypical anxiety, child characteristics, anxiety predictors and ASD-symptomology were explored. Fifty-nine participants (7-17 years, M(age) = 10.48 years; IQ > 60) with ASD and parents completed semi-structured interviews, self- and parent-reports. Seventeen percent of youth presented with traditional anxiety, 15 % with atypical anxiety, and 31 % with both. Language ability, anxious cognitions and hypersensitivity predicted traditional anxiety, whereas traditional anxiety and ASD symptoms predicted atypical anxiety. Findings suggest youth with ASD express anxiety in ways similar and dissimilar to DSM definitions. Similarities support the presence of comorbid anxiety disorders in ASD. Whether dissimilarities are unique to ASD requires further examination.

    A rare case of neuromyelitis optica spectrum disorder, suspected to be bacterial meningomyelitis as the initial manifestation, is reported. The patient presented with initial symptoms of meningomyelitis and fever. Cerebrospinal fluid analysis revealed pleocytosis (1280×10(6)/L [98% lymphocytes]) and glucose level of 1.8mmol/L. Magnetic resonance imaging revealed >3 vertebral, longitudinally extensive transverse myelitis and area postrema lesions. Right optic neuritis was experienced 20months after the first attack. Serum anti-aquaporin-4 antibody was positive, and a diagnosis of neuromyelitis optica spectrum disorder was made, supporting the hypothesis that the pathogenesis of neuromyelitis optica is triggered by infection.

    Full Text Available Background: To determine the incidence and demographic characteristics of skin diseases presenting with hyperpigmentation in children applying to the dermatology department. Methods: A total of 2815 children between the ages of 0 to 16 who applied to the dermatology clinic with the complaints of hyperpigmentation disorders were evaluated. The age, gender, socioeconomic status, place of residence and demographic characteristics of children with abnormal pigmentation skin lesions were investigated. Results: A total of 2815 children applied to the dermatology clinic during the study period. Of these patients 1491 were female (53% and 1324 were male (47%. Of these 266 (9.4% were diagnosed with skin disorders presenting with hyperpigmention. The causes of hyperpigmentation in these patients were was follows; pityriasis alba (2.6%, melanocytic nevus (2.1%, vitiligo (1.8% postinflammatory hyperpigmentation (0.5%, and postinflammatory hypopigmentation (0.5%. According to the gender, p.alba, vitiligo, Becker nevus, acanthosis nigricans, tuberosclerosis and albinism were seen more in boys and nevus depigmentosus ephelis, postinflammatory hyperpigmentation/hypopigmentation and melanocytic nevus were seen more in the girls. Pitriyazis versicolor was seen equally in both genders. According to age groups, melanocytis nevus were found to be more frequent between the ages of 0-2 and 12-16, whereas pityrsasis versicolor was more frequent in ages 12-16 and P. alba in the 3-11 age group. Conclusions: There are quite a substantial number of pigmentation diseases occurring in children. Early diagnosis and treatment are important because although these diseases mainly cause cosmetic problems, they can decrease the quality of life. Here, we attempted to define the demographic characteristics of diseases presenting with disorders in pigmentation in children.

    Delusion of parasitosis is a rare condition characterised by an individual harbouring the delusion of being infested with insects or parasites. We report a rare and interesting case of delusion of parasitosis presenting as folie a deux, that is, the delusion is shared by both the parents of an 18-month-old child, with proxy projection of parental delusion on the child. The case highlights the rare concomitant occurrence of two psychocutaneous disorders and emphasizes the importance of early recognition and appropriate intervention to safeguard the well-being of the child. © 2016 The Australasian College of Dermatologists.

Entitled Radio Beyond Borders the dossier gathers six articles and the intention of reuniting works on the perspectives of usage of such media as much as on the new possibilities of aesthetical experimenting being build up for it, especially considering the new digital technologies and technological convergences. It also intends to present works with original theoretical approach and original reflections able to reset the way we look at what is today already a centennial media. Having broadened the meaning of “beyond borders”, four foreign authors were invited to join the dossier. This is the first time they are being published in this country and so, in all cases, the articles where either written or translated into Portuguese.The dossier begins with “Radio is dead…Long live to the sound”, which is the transcription of a thought provoking lecture given by Armand Balsebre (Autonomous University of Barcelona – one of the most influential authors in the world on the Radio study field. It addresses the challenges such media is to face so that it can become “a new sound media, in the context of a new soundscape or sound-sphere, for the new listeners”.

    Full Text Available We present to our esteemed readers the second edition of our journal for 2008. We have chosen the theme “The life and work of Prof. Dr. Jürgen Moltmann” as its special emphasis. It is our way to pay homage to J. Moltmann in the year the Universidade Metodista de São Paulo awards him an honorary Doctor Honoris Causa degree. Sincethe seventies, Moltmann and Latin America have been in dialog. In his emblematic work “A Theology of Liberation”, Gustavo Gutiérrez, the Catholic, discussed with Moltmann, the Reformed, the relationship between eschatology and history (GUTIÉRREZ, Gustavo.Teologia da Libertação. 5ª edição. Petrópolis, RJ: Vozes, 1985, p. 27, 137-139. A dialog held in the premises of IMS, which nowadays is called UMESP, has produced the little book “Passion for life” (MOLTMANN, Jürgen. Paixão pela vida. São Paulo, SP: ASTE - Associaçãode Seminários Teológicos Evangélicos, 1978.In the following years, the wide theological work of J. Moltmann went all the way from debates to congresses and has conquered the classrooms. Most probably, J. Moltmann is nowadays the most widely read European author in Brazilian theological seminaries. Thisrecognition can only be held in unison and the wide response to our request for articles confirms the huge repercussion that Moltmann’s work has been having up to today in Brazil. The ecumenical theologian J. Moltmann is ecumenically read. We believe that thisway we may be better equipped to answer to anyone who asks us for the reason there is hope in us. We have organized the articles on J. Moltmann’s theology according to the original publication date of the books dealt with in each essay. We also communicate that some articles which were originally requested for this edition of the journal will be published in the journal Estudos de Regilião in May 2009.As it is usual with the journal Caminhando, we have, besides this thematic emphasis, yet other contributions in the areas of

    Attention-deficit hyperactive disorder (ADHD) is a psychiatric illness commonly diagnosed during the early years of childhood. In many adolescents with undiagnosed ADHD, presentation may not be entirely similar to that in younger children. These adolescents pose significant challenges to parents and teachers coping with their disability. Often adolescents with behavioural problems are brought to medical attention as a last resort. This case describes an adolescent who presented to a primary care clinic with school truancy. He was initially treated for depression with oppositional defiant disorder and sibling rivalry. Only following a careful detailed history and further investigations was the diagnosis of ADHD made. He showed a positive improvement with the use of methylphenidate for his ADHD and escitalopram for his depression. The success of his management was further supported by the use of behavioural therapy and parenting interventions. There is a need to increase public awareness of ADHD, especially among parents and teachers so that early intervention can be instituted in these children.

Skin biopsy revealed leukocytoclastic vasculitis. Laboratory tests demonstrated high levels of serum IgG and IgG4, hypocomplementemia and anticardiolipin antibody. Echography of the lower limbs and pulmonary scintigraphy showed a thrombus in the left soleal vein and multiple emboli in the basal part of both inferior pulmonary arteries. Computed tomography revealed systemic lymphadenopathy. Histologically, there was reactive paracortical hyperplasia with proliferation of histiocytes and infiltration of IgG4-positive plasma cells. We made a diagnosis of IgG4(+) -MOLPS with APS. To our knowledge, this complication has not been reported previously.

    Full Text Available Impulse control disorders (ICDs are characterized by an inability to resist an intense impulse or drive to perform a particular act that is excessive and/or harmful to self/others. Till date, there is no published report of an ICD presenting with repetitive urges to inflict burns. We describe the case of an adult male in regular follow-up for 6 months who presented with intense, irresistible, and repetitive urges and acts of causing burns on his skin for past 1 year. The phenomenology shared the core qualities described for ICDs and patient showed adequate response to treatment. The case report describes an unusual type of ICD classifiable as not otherwise specified. More clinical and research attention is warranted toward ICDs in general, with implications for ICD-11.

    Women who undergo treatment for infertility frequently report depression, but it is crucial to distinguish between subjective distress, symptoms, and clinical depressive disorders. In the initial assessment of a prospective, longitudinal study, 59 women presenting for infertility treatment were compared with 35 women presenting for routine gynecological care. Infertility patients and controls were not significantly different on self-report measures of partner satisfaction, sexual functioning, or self-esteem. There was also no difference in psychiatric symptomatology, or in the percentage of subjects who were currently experiencing or had ever experienced a major depressive episode. However, the infertility patients perceived themselves to have been already quite affected by their inability to conceive. For instance, 49.2% reported changes in their sexual functioning and 74.6% reported changes in their mood.

    During 20th century serious mental disorders were divided into two groups according symptomatology and course of disorder. Individuals with dominating disturbance of perception, thinking and cognition were basically diagnosed having schizophrenic. Individuals with mood disturbance were basically diagnosed having affective disorders. However, there were patients who did not fit neatly into either category. In 1933 Jocob Kasanin introduced the term "schizoaffective psychosis". Scientific discussions involved the possibility that schizoaffective disorder was conceptualized most accurately as following: a type of schizophrenia, a type of affective disorder, a unique disorder that was separate from both schizophrenia and bipolar disorder, an arbitrary categorization of clinical symptoms that marked a continuum between schizophrenia and affective illness, a heterogeneous collection of "interforms" between schizophrenia and affective disorders. However, diagnosis of schizoaffective disorder is included both in DSM-IV-TR and ICD-10. Schizoaffective disorder is listed in the category "schizophrenia and other psychotic disorders". The differential diagnosis includes basically either schizophrenia or affective disorder. The epidemiological status of schizoaffective disorder is somewhat uncertain compared with schizophrenia because of dilemmas related to diagnosis and classification of the disorder. Treatment of schizoaffective disorder comprises psychotropic medication, supportive psychotherapy, social care, rehabilitation. The most important groups of psychotropic medications are: antipsychotics, antidepressants and mood stabilizers. Atypical antipsychotics are the first-line medication for schizoaffective disorder due to their pharmacological properties. In the case of schizoaffective disorders combination of atypical antipsychotics with antidepressants seems to be useful. Novel antidepressants have priority for the combination mentioned above.

    Autoimmune lymphoproliferative syndrome (ALPS) is a rare disorder of disrupted lymphocyte homeostasis. Clinical manifestations of ALPS vary but typically include autoimmune cytopenias, organomegaly, lymphadenopathy, and increased risk of malignancies. A similar spectrum of symptoms may be seen in some patients with Evans syndrome (ES), a hematologic disorder defined by autoimmune destruction of at least 2 hematologic cell types. We hypothesized that a subset of patients diagnosed with ES may have ALPS. We screened 12 children with ES by flow cytometric analysis for CD4-/CD8- (double negative) T cells (DNTs) and with the definitive test for ALPS, defective in vitro Fas-mediated apoptosis. Six of the patients had elevated DNTs, suggestive of ALPS and also had defective Fas-mediated apoptosis. The other 6 patients displayed normal T-cell apoptosis; 5 of whom had normal DNTs, and 1 had a borderline result. Thus, 7 (58%) of 12 patients with ES had elevated DNTs suggestive of ALPS, with functional confirmation in 6 of 7. This suggests that analysis of DNTs may be a sensitive first-line screening test, serving as a marker of patients who should undergo definitive testing for ALPS. Our data further suggest that a number of patients with ES may have ALPS, a novel finding with important therapeutic implications.

    Full Text Available The aim of the present study was to compare a cohort of schizophrenia patients with substance use disorder (SUD with a similar cohort of schizophrenia patients without SUD with regard to sociodemographic variables, clinical variables, psychopathology, anxiety symptoms, depressive symptoms, treatment outcome, and side effect profile of drugs. A total of 143 consecutive inpatients with ICD-10 DCR diagnosis of schizophrenia were included after obtaining informed consent. Patients were evaluated by a semistructured data sheet and Maudsley Addiction Profile. They were then rated by Positive and Negative Symptoms Scale, Calgary Depression Scale, Hamilton Anxiety Rating Scale, and Brief Psychiatric Rating Scale at presentation, three weeks, and six weeks. At three weeks and six weeks, they were also evaluated by UKU Side Effect Rating Scale. Substance abuse was detected in 63.6% schizophrenia patients. Nicotine was the commonest substance followed by cannabis and alcohol. Substance users had longer untreated illness and more depressive symptoms at presentation and six-week follow-up. Dual diagnosis patients had difficulty in abstraction at three and six weeks but not at presentation. Schizophrenia patients with SUD had more depressive symptoms. SUD appeared to mask abstraction difficulties at presentation. Schizophrenia patients with SUD should be carefully assessed for presence of depression.

    Results of physical therapy evaluation of 112 patients with extensor mechanism disorders (chondromalacia patella, infrapatellar tendinitis, and peripatellar pain) are presented. An equal number of male and female patients were evaluated and of the 73 patients with unilateral involvement (65%) there were equal numbers of right and left involved knees. Running was the activity most commonly associated with pain, followed by basketball and tennis. Stairclimbing was painful in 79% of the patients, with ascending being more painful than descending in patients reporting a clear-cut difference. Hamstring and quadriceps tightness was statistically significant relative to the uninvolved limb although clinically, negligible differences were measured. The inferior pole of the patella was the most tender site to palpation, followed by medial peripatellar structures, then lateral sites. Biomechanical malalignment was not detected by the attending therapist in the majority of patients. The authors emphasize careful assessment of flexibility, quadriceps (VMOIVL) imbalance, and biomechanical alignment in performing a thorough evaluation of patients with extensor mechanism disorders.

    Autism, characterized by an impairment in communication, including language, narrowly focused interests, and poor sociability, is a neurodevelopmental disorder of still largely unknown pathogenesis. In children with autistic symptomatology, the most consistent functional or anatomic abnormalities are found in the cingulate gyrus, particularly in the anterior regions. Neuronal migration malformations caused by incomplete neuronal migration and characterized by loss of the normal gyral patterns in the cerebral hemispheres and prominent disorganization of the cerebral cortical cytoarchitecture are generally associated with profound neurologic deficits, epilepsy, and autism. In this report, we present a case with an isolated migration abnormality located in the anterior part of the left cingulate gyrus who was admitted with the complaints of epileptic seizures and autism. In addition, the role of the localization of the migration abnormality in the appearance of autistic symptomatology is discussed.

    Autoimmune lymphoproliferative syndrome (ALPS) is characterised by massive enlargement of the lymphoid organs, autoimmune cytopenias and a predisposition to develop lymphoid malignancies. The basic defect is a disturbance of the lymphocyte apoptosis, and a high number of circulating TCRab CD3(+)CD4(-)CD8(-) T-cells (double-negative T cells (DNT cells)). We describe a case of a 41-year-old man with fever, hepatosplenomegaly, multiple lymphadenopathy, autoimmune haemolytic anaemia and severe thrombocytopenia. Peripheral blood immunophenotyping revealed elevation of the characteristic DNT cells in 8% and high levels of interleukin 10. Histopathological analysis of lymph nodes showed lymphadenitis with paracortical hyperplasia. It was assumed as a probable diagnosis of ALPS, and the procedure was to medicate the patient with steroids. As a result, a significant clinical improvement was achieved, and he has been in remission for 2 years. To our knowledge, this is the first case reported in a Portuguese adult patient.

    The perplexing and tantalizing disease of rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by peculiar, potentially dangerous behavior during REM sleep. It was described both in animals and humans. RBD in mammals was first described by Jouvet and Delorme in 1965, based on an experimental model induced by lesion in pontine region of cats. In 1972, Passouant et al. described sleep with eye movements and persistent tonic muscle activity induced by tricyclic antidepressant medication, and Tachibana et al., in 1975, the preservation of muscle tone during REM sleep in the acute psychosis induced by alcohol and meprobamate abuse. wever, the first formal description of RBD in humans as new parasomnia was made by Schenck et al in 1986. Subsequently, in 1990, the International Classification of Sleep Disorders definitely recognized RBD as new parasomnia. To our knowledge, arts and literature do not mention RBD. Except for the quotation, made by Schenck et al [n 2002, of Don Quixote de la Mancha whose behavior in sleep strongly suggested that Miguel de Servantes actually described RBD, no other artistic work has portrayed this disorder. Only recently we become aware of the cinematic presentation of RBD which by decades precedes the first scientific description. The first presentation of RBD on film was made prior to the era of advanced electroencephalography and polysomnography, and even before the discovery of REM sleep by Aserinsky and Kleitman in 1953. The artistic and intuitive presentation of RBD was produced in Technicolor in a famous film "Cinderella" created by Walt Disney in 1950, some 35 years prior to its original publication in the journal "Sleep". Since there is an earlier version of the film initially produced in 1920, presumably containing this similar scene, we can only speculate that the first cinematic presentation of RBD might precede its scientific debut by 65 years.

    Hyperglycemia is seldom described in young patients with pituitary gigantism. Here, we describe the case of a 17-year-old Taiwanese boy who developed depressive mood disorder and diabetic ketoacidosis (DKA) at the presentation of pituitary gigantism. The boy complained of lethargy and dysphoric mood in June 2008. He presented at the emergency department with epigastralgia and dyspnea in January 2009. Results of laboratory tests suggested type 1 diabetes mellitus with DKA. However, serum C-peptide level was normal on follow-up. Although he had no obvious features of acral enlargement, a high level of insulin-like growth factor 1 was detected, and a 75 g oral glucose suppression test showed no suppression of serum growth hormone levels. A pituitary macroadenoma was found on subsequent magnetic resonance imaging. The pituitary adenoma was surgically removed, followed by gamma-knife radiosurgery, and Sandostatin long-acting release treatment. He was then administered metformin, 500 mg twice daily, and to date, his serum glycohemoglobin has been <7%.

    Full Text Available Objective To describe characteristics of REM sleep behavior disorder in Wilson’s disease. Method Questionnaire-based interviews (patients and relatives, neurological examinations, two-week prospective dream-diary, video-polysomnography, transcranial sonography, MRI. Results Four Wilson’s disease cases with REM sleep behavior disorder were described; three had REM sleep behavior disorder as initial symptom. All showed mesencephalic tegmental/tectal sonographic hyperechogenicities and two presented ponto-mesencephalic tegmental MRI hyperintensities. Conclusion This first description of REM sleep behavior disorder in Wilson’s disease in literature documents REM sleep behavior disorder as a possible presenting symptom of Wilson’s disease and adds further evidence to the parallelism of Parkinson’s disease and Wilson’s disease in phenotype and brainstem topography, which ought to be further studied. REM sleep behavior disorder has prognostic relevance for neurodegeneration in α-synucleinopathies. In Wilson’s disease, usefulness of early diagnosis and treatment are already well established. REM sleep behavior disorder in Wilson’s disease offers a possible theoretical model for potential early treatment in this extrapyramidal and brainstem paradigm syndrome, previewing the possibility of neuroprotective treatment for REM sleep behavior disorder in “pre-clinical” Parkinson’s disease.

    Full Text Available Background: Lymphoid malignancies are a heterogeneous group of disorders which may be difficult to differentiate from reactive proliferations even after immunohistochemistry. Polymerase chain reaction (PCR is believed to be a good adjunct tool for diagnosis. Materials and Methods: We examined 24 cases of neoplastic and non-neoplastic lymphoproliferative lesions in this study and evaluated the PCR as an additional tool in the confirmation of the diagnosis. Two different PCR methodologies were evaluated. Results: In the evaluation of the T-cell PCR, it was seen that the correlation using both the commercial kits and the custom-synthesized primers was highly significant at a P value of 0.05. Conclusions: Both the methods showed an excellent concordance for T-cell γ gene rearrangements, However, the same was not seen in the B-cell receptor rearrangements. This may be because of the small sample size or the inability of consensus V primers to recognize complementary DNA sequences in all of the V segments.

    Autoimmune lymphoproliferative syndrome (ALPS) is a human disorder characterized by defective Fas signaling, resulting in chronic benign lymphoproliferation and accumulation of TCRαβ(+) CD4(-) CD8(-) double-negative T (DNT) cells. Although their phenotype resembles that of terminally differentiated or exhausted T cells, lack of KLRG1, high eomesodermin, and marginal T-bet expression point instead to a long-lived memory state with potent proliferative capacity. Here we show that despite their terminally differentiated phenotype, human ALPS DNT cells exhibit substantial mitotic activity in vivo. Notably, hyperproliferation of ALPS DNT cells is associated with increased basal and activation-induced phosphorylation of serine-threonine kinases Akt and mechanistic target of rapamycin (mTOR). The mTOR inhibitor rapamycin abrogated survival and proliferation of ALPS DNT cells, but not of CD4(+) or CD8(+) T cells in vitro. In vivo, mTOR inhibition reduced proliferation and abnormal differentiation by DNT cells. Importantly, increased mitotic activity and hyperactive mTOR signaling was also observed in recently defined CD4(+) or CD8(+) precursor DNT cells, and mTOR inhibition specifically reduced these cells in vivo, indicating abnormal programming of Fas-deficient T cells before the DNT stage. Thus, our results identify the mTOR pathway as a major regulator of lymphoproliferation and aberrant differentiation in ALPS.

    Marco Cavicchioli

    2015-08-01

    Full Text Available Objective: Recently, some studies have been examining the relationship between Borderline Personality Disorder (BPD features and Experiential Avoidance (EA, Thought Suppression (TS and Distress Intolerance (DI. This interest arose from data which showed a strong link between the previous constructs and problematic behaviors (e.g. self-harm related to BPD. These dimensions describe a more general inability to withstand undesirable present-moment experiences. The aims of this work are to evaluate the extent of this problem in BPD and to hypothesize if it would be considered another core feature of BPD in addition to emotion dysregulation. Method: We included studies which show relationships between BPD features and EA, TS, DI, using valid and reliable instruments (e.g. PAI-BOR; AAQ; WBSI; DTS. Cohen’s d was computed as effect size measure. Overall pooled effect sizes (dw was estimated. Heterogeneity in effect sizes was computed using Q statistic and I² index. We proposed multiple comparisons of each outcome variable using Bonferroni correction. Bias publication was evaluated (Egger’s regression. Results: The final sample included 21 studies (4823 subjects. Large effect sizes were found in general inability to withstand present-moment experiences (dw= 0,92, EA (dw= 0,98 and TS (dw= 1,04. Medium effect size emerged in DI (dw= 0,60. It was observed high heterogeneity for overall effect size (I² =79,51%. Publication bias was not detected. Further, DI was significantly less manifest than EA and TS in BPD. Conclusions: These results show that the inability to withstand present-moment experiences is largely manifest in BPD and they suggest that this difficulty it might represent another core feature of BPD. These findings support mindfulness-based intervention in treating BPD. In addition, future research will be necessary to explain the relationship between emotion dysregulation, EA, TS and DI.

    A 30-year-old female with a history of anxiety, cannabis use, and Avoidant/Restrictive Food Intake Disorder presented for residential treatment of a Cannabis Use Disorder. Upon arrival, she had not eaten for two days and was found to be hypotensive with electrolyte disturbances. She was admitted to a nearby hospital, where the Internist diagnosed her with Addison's disease. She was treated with corticosteroid therapy, with rapid normalization of her electrolytes, eating, and anxiety. This is the first published case of undiagnosed Addison's disease presenting as an eating disorder, with cannabis use likely contributing to symptoms. This case elucidates the importance of ruling out other biologic and psychologic causes of clinical presentations before an eating disorder diagnosis can be made.

    Full Text Available Childhood disintegrative disorder (CDD is a rare autistic-like clinical condition with unknown etiology, in that previously acquired age-appropriate language, social and adaptive abilities deteriorate significantly in 2-10-year-old healthy children, although physical and neurological evaluations display no observable abnormality. Our case is a 22-year-old female born of a consanguineous marriage, with the appearance of CDD symptoms in her fifth year of age following normal mental and physical development during her initial four years of life. Without any precipitating factor, she gradually lost her language abilities, social relational skills, affectionate behavior, adaptive capacities, peer play and meaningful interest in her surrounding, friends and family members over a period of 4 years, reaching a plateau in her ninth year of age. The unique special clinical symptom in this case is a seasonal total mutism, which after the beginning of her CDD symptoms is revealing every year covering the spring. As no additional physical or psychological change accompanies her total seasonal speech loss, it cannot be attributed to any mental condition known as having a seasonal pattern. Because in the literature CDD is presented mostly as case reports with lacking of advanced research data, describing any new case is recommended to improve the knowledge about this rare condition, especially if it displays some new unusual signs, not reported till now.

"n "nMethod: Records of 13,968 patients seen between 1983-1985 and 2003- 2005 were reviewed for symptoms of catatonia by resident doctors in psychiatry. Cases in which the diagnosis were schizophrenia or mood disorder were then noted. Socio-demographic and clinical features were described for each diagnosis. "nResults: There were a total of 98 cases with catatonia out of the 13,968 case notes reviewed. Schizophrenia accounted for 82.5% and 53.4% in the two periods, while the proportion associated with mood disorders increased from 10% to 20.7%. Male to female  ratio was 1.2:1 in schizophrenia and 1:3 in mood disorder. Those with schizophrenia were younger and with an earlier age of onset of symptoms than those with mood disorders. "nConclusion:Catatonia associated with mood disorder was found to be increasing over the years when compared with schizophrenia. Differences were observed in socio-demographic characteristics and number of predominant catatonic symptoms. Having a separate category for catatonia due to the mood disorders in the current diagnostic guidelines (10th edition of the International Classification of Diseases and the 4th edition of the Diagnostic and Statistical Manual will help in better diagnosis of catatonia.

    Despite its long history as a psychiatric diagnosis, little is known about the sociodemographic and clinical profile of persistent delusional disorder (PDD) or its subtypes, treatment response, and outcomes, particularly in India. We examined the clinical characteristics and course of PDD in patients presenting to a tertiary neuropsychiatry center in India. A retrospective chart review of patients diagnosed with PDD (ICD-10) between January 2000 and May 2014 was conducted. Sociodemographic and clinical data including age at onset, total duration of the illness, clinical symptoms and treatment, hospitalizations, occupational functioning, and follow-up were extracted from the files. The study was approved by the institute ethics committee. The sample (N = 455) consisted of 236 men and 219 women. The mean age at onset was 32.36 ± 10.47 years. The most common delusion was infidelity (n = 203, 44.6%) followed by persecution (n = 149, 32.7%). Hallucinations were present in 78 (17.1%), depressive symptoms in 187 (41.1%), and comorbid substance dependence in 61 (13.4%) subjects; 141 subjects (31.0%) had a family history of mental illness. Follow-up data were available for 308 subjects, of whom 285 (92.5%) reported good compliance with medication. Of the subjects, 163 (52.9%) showed a good response to treatment. The diagnosis of PDD remained unchanged in 274 of 308 subjects (88.9%). In our center, PDD appears to be uncommon and has a near-equal gender representation. Infidelity was the most common delusion, which is in contrast to the reported literature. The diagnosis of PDD appears to be stable with good response to atypical antipsychotics if compliance can be ensured.

    Full Text Available Mental disorders affect a great number of people worldwide. Four out of the 10 leading causes of disability in the world are mental disorders. Because of the scarcity of specialists around the world and especially in developing countries, it is important for primary care physicians to provide services to patients with mental disorders. The most widely researched and used psychological approach in primary care is cognitive behavioral therapy. Due to its brief nature and the practical skills it teaches, it is convenient for use in primary care settings. The following paper reviews the literature on psychotherapy in primary care and provides some practical tips for primary care physicians to use when they are faced with patients having mental disorders.

    Full Text Available A 7-year-old girl presented with recurrent episodes of petechiae, purpura and ecchymoses since six months of age and recurrent episodes of mild to severe epistaxis since two years of age requiring repeated blood transfusions. In April '99 while being investigated for a massive epistaxis, she was found to have platelet function defect with abnormal aggregation of platelets to ADP, epinephrine, collagen as well as to ristocetin. Further investigations ruled out the possibility of Glanzmann's disorder and von-Willebrand's disease as to its cause. In May 2001 she was referred to the dermatologist for evaluation of subcutaneous tumours, which had developed since the last six months. On clinical evaluation, she was found to be having mild hyperextensibility of the skin, joint hypermobility, atrophic scars over knee, spontaneous bruises over right forearm and left thigh and nontender firm to hard subcutaneous nodules over both wrists, both shoulders, right index finger and dorsum of right foot consistent with a clinical picture of a mild form of Ehlers-Danlos syndrome (EDS. Histopathology of the nodule from left wrist was consistent with molluscoid tumour of EDS and skin histopathology and ultrastructure studies showed thick irregular collagen fibrils. Only other sibling, a five-year-old male also had history of repeated mild to moderate epistaxis and on examination was found to have a milder variant of EDS. Born out of I degree consanguineous marriage of normal parents with mildly affected other sibling, she was diagnosed to be suffering from EDS with autosomal recessive inheritance, most probably EDS type X due to the associated platelet aggregation defect. Only one such family with EDS type X has been reported so far.

    Full Text Available Objective: The aim of the present study was to test hypothesis that obsessive compulsive disorder (OCD patients who have autogenous obsessions and reactive obsessions show different sociodemographic and clinical characteristics with different insight and cognitive insight levels. Method: Sixty-one patients diagnosed as OCD according to the Structured Clinical Interview for DSM-III-R (SCID-I are recruited. 31 patients had reactive obsessions and 30 had autogenous obsessions. The sociodemographic characteristics of patients and the symptomatology were evaluated using psychiatric scales including SCID-I, Yale Brown Obsessive- Compulsive Scale (YBOCS, Yale Brown Obsessive-Compulsive Scale-Symptom Checklist (YBOCS-SC and Beck Insight Scale. Results: The percentage of women in reactive obsessive group was higher and also this group had significantly less antipsychotic medication prescribed than the autogenous obsessive group. No significant difference was found for the other demographic variables. No significant difference was identified for the Beck Insight Self-Reflectiveness subscale but for the Self-Certainty subscale, reactive obsessives had higher scores. Although there was no significant difference for the composit index points, which is the subtraction of the two subscales, the p value was close to the limit. On the other hand YBOCS item- 11 scores which evaluates insight were higher in autogenous obsessives meaning low levels of insight. Conclusion: For the sociodemographic and clinical characteristics; there was no significant difference between the groups except gender distribution and antipsychotic medication. Our data about insight seems inconsistent but insight and cognitive insight can be different entities which show different levels of insight. Further investigation with different obsession types is needed.

    While a relationship has been identified between physical aggression and executive functioning within the adult population, this relationship has not yet been consistently examined in the adolescent population. This study examined the association between physical aggression towards others, self-reported depressive symptoms, and executive functioning within an adolescent inpatient sample diagnosed with a mood disorder. This study consisted of a retrospective chart review of 105 adolescent inpatients (ages 13-19) that received a diagnosis of a mood disorder (excluding Bipolar Disorder). Participants were grouped based on history of aggression towards others, resulting in a mood disorder with physically aggressive symptoms group (n = 49) and a mood disorder without physically aggressive symptoms group (n = 56). Ten scores on various measures of executive functioning were grouped into five executive functioning subdomains: Problem Solving/Planning, Cognitive Flexibility/Set Shifting, Response Inhibition/Interference Control, Fluency, and Working Memory/Simple Attention. Results from analyses of covariance indicated that there were no significant differences (p executive functioning subdomains.

    Full Text Available BACKGROUNDPatient’s anamnesis is of primary importance in determining hemostatic disorders. Based on anamnestic data, a clinician may decide for further laboratory tests. We must consider an acquired bleeding disorder in a patient with unusual, unexpected and prolonged bleeding episodes. In this article we will describe two rare acquired hemostatic disordes.TWO CASE REPORTSOur first patient had prolonged bleeding after a pacemaker implantation. We diagnosed him with acquired von Willebrand syndrome. Further on, the patient required a planned surgical procedure. In our second case we describe a patient with unusual and excessive skin bruising and prolonged bleeding after teeth extractions. He was diagnosed with acquired hemophilia.CONCLUSIONIn the assessment of a patient with a potential acquired bleeding disorder we must first rule out the most common causes, such as iatrogenic ones. But, because of high morbidity and mortality rates, we must also be aware of some rare acquired bleeding disorders. In case of uncertainty, we should consult with a hematologist.

    X-linked lymphoproliferative disease (XLP) is an inherited immune defect caused by mutations in the Src homology 2 domain-containing gene 1A, which encodes the adapter protein, signaling lymphocytic activation molecule (SLAM)-associated protein (SAP). SAP is expressed in T cells, natural killer (NK) cells, and NKT cells, where it binds to the cytoplasmic domain of the surface receptor SLAM (CD150) and the related receptors, 2B4 (CD244), CD84, Ly9 (CD229), NK-T-B-antigen, and CD2-like receptor-activating cytotoxic T cells. SAP also binds to the Src family tyrosine kinase Fyn and recruits it to SLAM, which leads to the generation of downstream phosphotyrosine signals. While the roles of the SLAM family receptors are only beginning to be understood, experiments suggest that these molecules regulate important aspects of lymphocyte function, such as proliferation, cytokine secretion, cytotoxicity, and antibody production. Thus, in XLP patients who lack functional SAP, the SLAM family receptors may not signal properly. This property likely contributes to the phenotypes of XLP, including fulminant infectious mononucleosis, lymphoma, and hypogammaglobulinemia. Further studies of SAP and the SLAM family receptors will provide insights into XLP and elucidate the signaling events regulating lymphocyte ontogeny and function.

    2013-01-01

    Narcissistic personality disorder (NPD) and not otherwise specified personality disorder (borderline and narcissistic) are major mental health problems for men. These pathologies predispose patients to significant relational difficulties which are characterised by intense reactions to perceived threats to the self-esteem and an impaired empathic ability. Understanding these disorders as affect dysregulation stimulated by shame, the author presents how patients in this context are prone to lose their capacity to mentalize. This article describes a specific individual and group mentalization-based treatment and its implementation for treating narcissistic men. Different reflections on the treatment, on empathy, as well as on the adaptation of this treatment for NPD patients are presented and illustrated with clinical vignettes.

    Full Text Available Bipolar disorder is a significant cause of morbidity and mortality. Although existing treatments are effective, there is often a substantial delay before diagnosis and treatment initiation. We sought to investigate factors associated with the delay before diagnosis of bipolar disorder and the onset of treatment in secondary mental healthcare.Retrospective cohort study using anonymised electronic mental health record data from the South London and Maudsley NHS Foundation Trust (SLaM Biomedical Research Centre (BRC Case Register on 1364 adults diagnosed with bipolar disorder between 2007 and 2012. The following predictor variables were analysed in a multivariable Cox regression analysis: age, gender, ethnicity, compulsory admission to hospital under the UK Mental Health Act, marital status and other diagnoses prior to bipolar disorder. The outcomes were time to recorded diagnosis from first presentation to specialist mental health services (the diagnostic delay, and time to the start of appropriate therapy (treatment delay.The median diagnostic delay was 62 days (interquartile range: 17-243 and median treatment delay was 31 days (4-122. Compulsory hospital admission was associated with a significant reduction in both diagnostic delay (hazard ratio 2.58, 95% CI 2.18-3.06 and treatment delay (4.40, 3.63-5.62. Prior diagnoses of other psychiatric disorders were associated with increased diagnostic delay, particularly alcohol (0.48, 0.33-0.41 and substance misuse disorders (0.44, 0.31-0.61. Prior diagnosis of schizophrenia and psychotic depression were associated with reduced treatment delay.Some individuals experience a significant delay in diagnosis and treatment of bipolar disorder after initiation of specialist mental healthcare, particularly those who have prior diagnoses of alcohol and substance misuse disorders. These findings highlight a need for further study on strategies to better identify underlying symptoms and offer appropriate treatment

    Full Text Available A 70-year-old female presented with a 4-week history of dry cough and wheezing. Chest radiograph showed a 10.5 cm mass-like density in the anterior mediastinum which had not been previously visualized. Computed tomography scan (CT of the chest showed a right hilar mass encasing and narrowing right upper lobe bronchus and right mainstem bronchus and secondary atelectatic changes. Biopsy was consistent with a diagnosis of lymphomatoid granulomatosis Grade 3. She responded well clinically and radiologically to therapy. Lymphomatoid granulomatosis is a rare EBV-associated disorder which is considered a lymphoproliferative disease. The most common radiographic feature is multiple lung nodules. An isolated hilar mass is an exceptionally rare presentation of this rare disease.

  3. Newborn screening of inherited metabolic disorders by tandem mass spectrometry: past, present and future

    Directory of Open Access Journals (Sweden)

    G. Scaturro

    2013-04-01

    Full Text Available Inborn errors of metabolism are inherited biochemical disorders caused by lack of a functional enzyme, transmembrane transporter, or similar protein, which then results in blockage of the corresponding metabolic pathway. Taken individually, inborn errors of metabolism are rare. However, as a group these diseases are relatively frequent and they may account for most of neonatal mortality and need of health resources. The detection of genetic metabolic disorders should occur in a pre-symptomatic phase. Recently, the introduction of the tandem mass spectrometric methods for metabolite analysis has changed our ability to detect intermediates of metabolism in smaller samples and provides the means to detect a large number of metabolic disorders in a single analytical run. Screening panels now include a large number of disorders that may not meet all the criteria that have been used as a reference for years. The rationale behind inclusion or exclusion of a respective disorder is difficult to understand in most cases and it may impose an ethical dilemma. The current organization is an important tool of secondary preventive medicine, essential for children’s healthcare, but the strong inhomogeneity of the regional models of screening applied today create in the Italian neonatal population macroscopic differences with regards to healthcare, which is in effect mainly diversified by the newborn’s place of birth, in possible violation of the universal criterion of the equality of all citizens. Carefully weighed arguments are urgently needed since patient organizations, opinion leaders and politicians are pressing to proceed with expansion of neonatal population screening.

    Post-transplant lymphoproliferative disease (PTLD) is an invasive, EBV expressing B lymphoma and a major cause of morbidity and mortality following organ transplantation. Presently there is limited therapy available; rather the patient often loses the allograft or succumbs to the malignancy. CD77 (or globotriaosyl ceramide -Gb(3)) is a germinal center B cell marker [Gregory et al. Int J Cancer 1998;42:213-20; Gregory et al., J Immunol 1987;139:313-8; Mangeney et al. Eur J Immunol 1991;21:1131-40], expressed on most EBV infected B cells and is the receptor for the E. coli derived verotoxin (VT) [Lingwood CA. Advances in Lipid Research 1993;25:189-212]. We present the basis of a possible novel approach to PTLD therapy utilizing the specific targeting of VT to the infiltrating lymphoma cells. Biopsies of adenoid, kidney or liver tissue of four PTLD patients were stained with verotoxin to determine expression of CD77. VT is a potent inducer of necrosis/apoptosis of receptor positive cells. In each PTLD case, the infiltrating EBV positive B lymphoma cells were strongly and selectively stained with VT, identifying CD77 as a new marker for these cells. For such individuals, VT might provide the basis of an approach to control their malignancy.

    Lymphoma is seen in up to 30% of patients with X-linked lymphoproliferative disease (XLP), but cerebral vasculitis related with XLP after cure of Burkitt lymphoma is rarely reported. We describe a case of a 5-year-old boy with XLP who developed cerebral vasculitis two years after cure of Burkitt lymphoma. He had Burkitt lymphoma at the age of 3 years and received chemotherapy (non-Hodgkin’s lymphoma-Berlin-Frankfurt-Milan-90 protocol plus rituximab), which induced complete remission over the following two years. At the age of 5 years, the patient first developed headache, vomiting, and then intel ectual and motorial retrogression. His condition was not improved after anti-infection, dehydration, or dexamethasone therapy. No tumor cells were found in his cerebrospinal fluid. Magnetic resonance imaging showed multiple non-homogeneous, hypodense masses along the bilateral cortex. Pathology after biopsy revealed hyperplasia of neurogliocytes and vessels, accompanied by lymphocyte infiltration but no tumor cell infiltration. Despite aggressive treatment, his cognition and motor functions deteriorated in response to progressive cerebral changes. The patient is presently in a vegetative state. We present this case to inform clinicians of association between lymphoma and immunodeficiency and explore an optimal treatment for lymphoma patients with compromised immune system.

    Visceral hypersensitivity and abnormal coping are common in children with functional abdominal pain disorders (FAPDs). Thus, it would be expected that children with visceral hypersensitivity would report more pain if their gut is acutely inflamed. The aim of the study was to compare clinical symptoms and somatization of children with and without FAPDs at time of an episode of acute gastroenteritis. Seventy children with acute gastroenteritis and their parents completed the Rome III Diagnostic Questionnaire for Pediatric Functional GI Disorders and the Children's Somatization Inventory. Twenty-one percent of children were diagnosed with an FAPD. Children with FAPDs showed significantly more nongastrointestinal somatic symptoms than children without FAPDs. There were no significant differences in abdominal pain, nausea, vomiting, or school absenteeism between both groups at time of consultation.

    Occlusion has been an important consideration in orthodontics since the beginning of the discipline. Early emphasis was placed on the alignment of the teeth, the stability of the intercuspal position, and the esthetic value of proper tooth positioning. These factors remain important to orthodontists, but orthopedic principles associated with masticatory functions must also be considered. Orthopedic stability in the masticatory structures should be a routine treatment goal to help reduce risk factors associated with developing temporomandibular disorders.

    Full Text Available Ovotesticular disorder of sex development (OT-DSD is a rare disorder of sexual differentiation characterized by the presence of both ovarian and testicular tissues in the same individual. It's incidence ranges from 3% to 10% of all disorder of DSD's, and the most common presentation is 46, XX followed by 46, XX/46, XY mosaicism and 46, XY. Klinefelter syndrome (KS mosaicism 46, XX/47, XXY is extremely rare, and its association with the ovotesticular disorder is even rarer. We report an unusual case of 16-year-old with male habitus who presented with complains of cyclic hematuria. On examination, he had bilateral gynecomastia, unilateral left cryptorchidism, absent facial hair, sparse axillary hair growth, and pubic hair distribution of feminine type. The right testis was of normal size located normally in hemiscrotum and was confirmed by radio imaging. Ultrasonography and magnetic resonance imaging revealed a cystic area behind posterior half of urinary bladder. Chromosomal analysis revealed 46, XX/47, XXY mosaicism of female karyotype and KS. Histopathological report of this left side excised specimen confirmed the structures to be ovary, uterus, and fallopian tube, thus confirming our diagnosis of the lateral ovotesticular disorder. Meticulous workup combined interdisciplinary approach will lead to early diagnosis and resolve timely sex reassignment issues and also prevent consequences arising due to gonadal insufficiency.

    We report the case of a 46-year-old Japanese woman with neuromyelitis optica spectrum disorder presenting with repeated hypersomnia accompanied by decreased CSF orexin level. First episode associated with hypothalamic-pituitary dysfunction showed bilateral hypothalamic lesions that can cause secondary damage to the orexin neurons. The second episode associated with impaired memory showed a left temporal lesion involving the amygdala. The mechanism remains unknown, but the reduced blood flow in the hypothalamus ipsilateral to the amygdala lesion suggested trans-synaptic hypothalamic dysfunction secondary to the impaired amygdala. A temporal lesion involving the amygdala and hypothalamus could be responsible for hypersomnia due to neuromyelitis optica spectrum disorder.

    2016-04-01

    Fascioliasis is an important zoonotic disease with approximately 2-4 million people infected worldwide and a further 180 million at risk of infection. F. hepatica can survive within the bile ducts for many years through its ability to suppress the host immunity with Fasciola cathepsin L1 cysteine protease and Glutathione S transferase playing an important role. The aim of the present study is to investigate the in vitro lympho-proliferative responses of hepatic hilar lymphocytes (HLN) of infected sheep in response to different F. hepatica antigens. The suppressive effects of Fasciola excretory/secretory (ES) and tegument (TEG) and their fractions were also investigated. Our results showed that both ES and TEG had significant suppressive effects on lympho-proliferation, up to 74% and 92%, respectively. When these antigens were fractionated, fraction 3 (MW of >10000-30000) of both ES (64%) and TEG (59%) in addition to fraction 4 (MW of ≤ 10000) of TEG (38%) inherited the suppressive effects. Identification of the potential molecule(s) with such suppressive effects on lymphocytes in TEG fraction 4 could reveal vaccine candidates.

  14. Inertial Sensing to Determine Movement Disorder Motion Present before and after Treatment

    2012-03-01

    Full Text Available There has been a lot of interest in recent years in using inertial sensors (accelerometers and gyroscopes to monitor movement disorder motion and monitor the efficacy of treatment options. Two of the most prominent movement disorders, which are under evaluation in this research paper, are essential tremor (ET and Parkinson’s disease (PD. These movement disorders are first evaluated to show that ET and PD motion often depict more (tremor motion content in the 3–12 Hz frequency band of interest than control data and that such tremor motion can be characterized using inertial sensors. As well, coherence analysis is used to compare between pairs of many of the six degrees-of-freedom of motions under evaluation, to determine the similarity in tremor motion for the various degrees-of-freedom at different frequency bands of interest. It was quite surprising that this coherence analysis depicts that there is a statistically significant relationship using coherence analysis when differentiating between control and effectively medicated PD motion. The statistical analysis uncovers the novel finding that PD medication induced dyskinesia is depicted within coherence data from inertial signals. Dyskinesia is involuntary motion or the absence of intended motion, and it is a common side effect among medicated PD patients. The results show that inertial sensors can be used to differentiate between effectively medicated PD motion and control motion; such a differentiation can often be difficult to perform with the human eye because effectively medicated PD patients tend to not produce much tremor. As well, the finding that PD motion, when well medicated, does still differ significantly from control motion allows for researchers to quantify potential deficiencies in the use of medication. By using inertial sensors to spot such deficiencies, as outlined in this research paper, it is hoped that medications with even a larger degree of efficacy can be created in

    The authors undertook the assessment of the available methods for the analysis of the sensations of patients suffering pathology of the vestibular analyzer. The fact that such conditions as dizziness and disequilibrium have great influence on the social status of a patient and his (her) position in society accounts for the use of functional stabilometry in the clinical practice along with the evaluation of quality of life. It is emphasized that the timely diagnosis of these disorders and elucidation of their primary causes are as important for the successful treatment of this pathology as the choice of an adequate course of medicamental and rehabilitative therapy.

    Although the syndrome of Multiple Personality Disorder (MPD) has received much interest in the international literature, there have been virtually no professional articles on the topic in German over the last 70 years. This is a report on two cases with nine and 70 persons respectively. Both had undergone severe and prolonged sexual abuse in childhood. Compared with DSM-III-R, the ICD-10 criteria seem to reflect historic reports on alternating personalities rather than recent empirical research on multiple personality. The proposed etiological model postulates that extreme trauma in childhood can result in dissociative vulnerability persisting into adulthood.

    2017-01-01

    Full Text Available Children often present to emergency departments (EDs with uncontrollable nose bleeding. Although usually due to benign etiologies, epistaxis may be the presenting symptom of an inherited bleeding disorder. Whereas most bleeding disorders are detected through standard hematologic assessments, diagnosing rare platelet function disorders may be challenging. Here we present two case reports and review diagnostic and management challenges of platelet function disorders with a focus on Glanzmann’s thrombasthenia (GT. Patient 1 was a 4-year-old boy with uncontrolled epistaxis. His medical history included frequent and easy bruising. Previous laboratory evaluation revealed only mild microcytic anemia. An otolaryngologist stopped the bleeding, and referral to a pediatric hematologist led to the definitive diagnosis of GT. Patient 2 was a 2.5-year-old girl with severe epistaxis and a history of milder recurrent epistaxis. She had a bruise on her abdomen with a palpable hematoma and many scattered petechiae. Previous assessments revealed no demonstrable hemostatic anomalies. Platelet aggregation studies were performed following referral to a pediatric hematologist, leading to the diagnosis of GT. As evidenced by these cases, the ED physician may often be the first to evaluate severe or recurrent epistaxis and should recognize indications for coagulation testing and hematology consultation/referral for advanced hematologic assessments.

    Intrinsically disordered proteins (IDP) form a large and functionally important class of proteins that lack an ordered three-dimensional structure. IDPs play an important role in cell signaling, transcription, or chromatin remodeling. The discovery of IDPs has challenged the traditional paradigm of protein structure which states that protein function depends on a well-defined three-dimensional structure. Due to their high conformational flexibility and the lack of ordered secondary structure, it is challenging to study the flexible structure, dynamics and energetics of these proteins with conventional methods. In our work, we employ photoinduced electron transfer (PET) combined with fluorescence correlation spectroscopy (FCS) for studying the conformational dynamics of one specific class of IDPs: phenylalanine-glycine rich protein domains (FG repeats) which are dominant building blocks within the pore of nuclear pore complexes. Nuclear pore complexes are large protein assemblies that cross the nuclear envelope and form selective barrier, which regulate bidirectional exchange between nucleus and cytoplasm.

    Full Text Available INTRODUCTION: Temporomandibular disorders (TMD have proved to be a risk factor for developing hyperdivergent facial growth patterns. OBJECTIVE: The aims of this study were: (1 Assess differences between the cephalometric measurements in children with articular TMD and a control group, before and after mandibular growth peak according to cervical vertebral maturation; and (2 Identify a predictive model capable of differentiating patients with TMD and control group patients based on early cephalometric characteristics. METHOD: The study included children and adolescents with maximum age of 17 years, divided into experimental group (n=30 diagnosed with articular TMD-according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD for children and adolescents-subdivided according to growth stage, called pre-peak (n=17 and post-peak (n=13 and control group (n = 30, matched by gender, skeletal maturity stage of the cervical vertebrae and classification of malocclusion. Lateral cephalometric and craniofacial structures were traced and their relations divided into: Cranial base, maxilla, mandible, intermaxillary relations, vertical skeletal relations and dental relations. Differences between the means for each variable were evaluated by applying the statistical Student t test for independent samples. RESULTS: The means of the variables analyzed in the pre-peak showed no statistically significant differences. However, analysis of post-peak showed that the experimental group displayed decreased SNA and SNB and increased SN.Gn and 1.NB (p<0.05. CONCLUSION: It was possible to identify a predictive model able to differentiate patients with TMD and asymptomatic controls from early cephalometric characteristics.

    Waldenstrom macroglobulinemia (WM) is a B-cell lymphoproliferative disorder associated with bone marrow involvement of lymphoplasmacytic lymphoma (LPL) and an IgM monoclonal gammopathy. Generally B-lymphocytes in LPL do not express CD5 that is important for differential diagnosis of B-cell lymphoproliferative disorders. In WM, various renal diseases and type I cryoglobulinemia are well described separately, but cryoglobulinemic glomerulonephropathy is very rarely reported. A 61-yr-old woman complained of generalized edema, cyanosis of the extremities in cold weather, visual disturbance, and pancytopenia. Bone marrow and renal biopsy showed CD5+ expressing B-cells and cryoglobulinemic glomerulonephropathy. With the diagnosis of WM, she received cyclophosphamide, doxorubicin, vincristine and prednisolone chemotherapy and got complete remission. Here, we report a rare case of WM associated with unusual expression of CD5+ B-lymphocytes and cryoglobulinemic glomerulonephropathy, and emphasize the importance of the clinical features in differentiating CD5+ B-cell lymphoproliferative disorders.

    Neuromyelitis Optica (NMO) can have atypical presentations like hiccups, vomiting, etc. which is classically described as the area postrema syndrome. Here we report a case of a 39 year old male patient who presented with features of Trigeminal Autonomic Cephalalgia (TAC). MRI spine showed long segment myelitis. Diagnosis of NMO was confirmed by a positive Anti aquaporin 4 antibody assay. TACs are a rare group of headache disorders characterized by severe unilateral headache in the V1 distribution of the trigeminal nerve and autonomic symptoms. This presentation in NMO is hitherto unreported in literature.

  4. Using biomarkers to predict treatment response in major depressive disorder: evidence from past and present studies.

    2014-12-01

    Major depressive disorder (MDD) is a heterogeneous condition with a variable response to a wide range of treatments. Despite intensive efforts, no biomarker has been identified to date that can reliably predict response or non-response to any form of treatment, nor has one been identified that can be used to identify those at high risk of developing treatment-resistant depression (ie, non-response to a sequence of treatments delivered for adequate duration and intensity). This manuscript reviews some past areas of research that have proved informative, such as studies using indexes of hypercortisolism or sleep disturbance, and more recent research findings using measures of inflammation and different indicators of regional cortical activation to predict treatment response. It is concluded that, although no method has yet been demonstrated to be sufficiently accurate to be applied in clinical practice, progress has been made. It thus seems likely that--at some point in the not-too-distant future--it will be possible to prospectively identify, at least for some MDD patients, the likelihood of response or non-response to cognitive therapy or various antidepressant medications.

    Lymphadenopathy in children for which no infectious or malignant cause can be ascertained constitutes a challenging diagnostic dilemma. Autoimmune lymphoproliferative syndrome (ALPS) is a human genetic disorder of lymphocyte apoptosis resulting in an accumulation of lymphocytes and childhood onset chronic lymphadenopathy, splenomegaly, multilineage cytopenias, and an increased risk of B-cell lymphoma. In 1999, investigators at the National Institutes of Health (NIH) suggested criteria to establish the diagnosis of ALPS. Since then, with approximately 500 patients with ALPS studied worldwide, significant advances in our understanding of the disease have prompted the need for revisions to the existing diagnostic criteria and classification scheme. The rationale and recommendations outlined here stem from an international workshop held at NIH on September 21 and 22, 2009, attended by investigators from the United States, Europe, and Australia engaged in clinical and basic science research on ALPS and related disorders. It is hoped that harmonizing the diagnosis and classification of ALPS will foster collaborative research and better understanding of the pathogenesis of autoimmune cytopenias and B-cell lymphomas.

Headache and features of increased intracranial tension are the common clinical manifestation. Report of psychiatric symptoms as the initial presentation of epidermoid is not known in literature except a single case report, which describes mutism to be the manifestation of intracranial epidermoid. We present here the case of a young male, who presented with long depressive episode persisting for 3 years with subsequent switch to mania, which persisted for more than 3 years. An episode of unconsciousness warranted neuroimaging, which revealed a large epidermoid of the quadrigeminal cistern. Surgical resection of the epidermoid was done. Persisting mood symptoms had responded to mood stabilizer and antipsychotic treatment.

    Background: Renal involvement in patients with lymphoproliferative disease is an uncommon radiological finding. Purpose: To determine its prevalence and radiological appearances in a patient population. Material and Methods: All forms of lymphoproliferative disease (ICD: C81-C96) were considered. From January 2005 to January 2010, 668 consecutive patients with lymphoproliferative disease were identified with the help of the radiological database and patient records. Inclusion criteria were complete staging including appropriate CT scan and/or MRI. All stored images (initial staging and follow-up examinations) were reviewed. Results: Review of all stored images revealed renal infiltration in patients with non-Hodgkin lymphoma (11 of 364 = 3.0%; median age = 65 years, m:f = 6:5) but also multiple myeloma (2 of 162 = 1.2%; median age = 72 years; m:f = 1:1) and leukemia (5 of 101 4.9%; median age = 12 years; m:f = 2:3). There were no cases of renal infiltration in 41 patients with Hodgkin's disease. In total there were six patients with solitary lesions, five patients with diffuse renal enlargement, four patients with perirenal lesions, and two patients with direct invasion of the kidney. Conclusion: In leukemia the most common imaging pattern is diffuse enlargement. In the other subtypes of lymphoproliferative disease no specific correlation between typical CT patterns and subtype of lymphoproliferative disease can be found. The prevalence of renal involvement is in line with earlier studies. Contrary to earlier reports, multiple lesions were not found to be a common pattern

    Full Text Available Spontaneous encoding of the visual environment depends on the behavioral relevance of the task performed simultaneously. If participants identify target letters or auditory tones while viewing a series of briefly presented natural and urban scenes, they demonstrate effective scene recognition only when a target, but not a behaviorally irrelevant distractor, appears together with the scene. Here, we show that individuals with posttraumatic stress disorder (PTSD, who witnessed the red sludge disaster in Hungary, show the opposite pattern of performance: enhanced recognition of scenes presented together with distractors and deficient recognition of scenes presented with targets. The recognition of trauma-related and neutral scenes was not different in individuals with PTSD. We found a positive correlation between memory for scenes presented with auditory distractors and re-experiencing symptoms (memory intrusions and flashbacks. These results suggest that abnormal encoding of visual scenes at behaviorally irrelevant events might be associated with intrusive experiences by disrupting the flow of time.

Diagnosis of the majority of T-cell LGLL is established by documenting clonal large granular lymphocytes (LGLs in peripheral blood, by morphology and immunophenotype. The proteasome inhibitor bortezomib is known to target molecular pathways downstream of the IL-15 receptor signaling and has been proposed as a therapy in these patients. We report an uncommon presentation of LGLL with chronic neutropenia lacking typical blood LGLs, which failed to respond to bortezomib but obtained a very good partial remission with a classical methotrexate regimen.

    Mammalian erythropoiesis is regulated primarily by the hormone erythropoietin (ESP). Studies of ESF have provided information about its biochemistry and its role in regulating hemoglobin synthesis. Such studies rely on assays for erythropoietic activity in biological fluid. The assay which has proven most valuable and is used most widely is based upon the incorporation of radioactive iron into newly-formed red cells of polycythemic mice. While this assay has gained wide acceptance, it is expensive, cumbersome, imprecise, and insensitive, capable of reliably detecting no less than 50 milliunits of erythropoietin. Improvements in assay techniques will require new methodology relying primarily on immunologic recognition for the determination of hormone activity. Currently under development and in experimental use are radioimmunoassays and a hemagglutination inhibition assay. While work has progressed in these areas, these assays are not of proven value at present and meaningful physiological correlations have not emerged from their use. Alternatively, assays for hormone activity using suspensions of hematopoietic cells and the measurement of incorporation of radioactive isotopes into hemoglobin have provided both improvement in sensitivity and precision. The disadvantage of these types of assays is that they are sensitive to factors other than ESF and may give misleading information, depending on whether the factors present stimulate or inhibit cellular proliferation and hemoglobin synthesis. While such techniques may provide a temporary solution to some problems associated with assaying ESF for purification or physiological studies, they are not the best answer to the overall problem of hormone detection and characterization. The most important contribution to this field will be the availability of large amounts of highly purified and well-characterized ESF.

    Children with attention deficit hyperactivity disorder (ADHD) often fail to comply with teacher instructions in the classroom. Using action during presentation or recall can enhance typically developing children's abilities to complete multi-step instruction sequences. In this study, we tested the ability to following instructions in children with ADHD under different conditions to explore whether they show the same beneficial effects of action. A total of 24 children with ADHD and 27 typically developing children either listened to or viewed demonstrations of instructions during encoding, and then either verbally repeated or physically performed the sequences during recall. This resulted in four conditions: spoken-verbal, spoken-enacted, demonstration-verbal, and demonstration-enacted. Children with ADHD were significantly impaired in all conditions of the following instructions task relative to the typically developing group. Both groups showed an enacted-recall advantage, with superior recall by physical performance than oral repetition. Both groups also benefitted from demonstration over spoken presentation, but only when the instructions were recalled verbally. These findings suggest that children with ADHD struggle to complete multi-step instructions, but that they benefit from action-based presentation and recall in the same way as typically developing children. These findings have important implications for educators, suggesting that motor-based methods of instruction-delivery might enhance classroom learning both for children with and without developmental disorders.

    The purpose of this study was the appraisal of the clinical and functional consequences of germline mutations within the gene for the IL-2 inducible T-cell kinase, ITK. Among patients with Epstein-Barr virus-driven lymphoproliferative disorders (EBV-LPD), negative for mutations in SH2D1A and XIAP (n=46), we identified two patients with R29H or D500T,F501L,M503X mutations, respectively. Human wild-type (wt) ITK, but none of the mutants, was able to rescue defective calcium flux in murine Itk(-/-) T cells. Pulse-chase experiments showed that ITK mutations lead to varying reductions of protein half-life from 25 to 69% as compared with wt ITK (107 min). The pleckstrin homology domain of wt ITK binds most prominently to phosphatidylinositol monophosphates (PI(3)P, PI(4)P, PI(5)P) and to lesser extend to its double or triple phosphorylated derivates (PIP2, PIP3), interactions which were dramatically reduced in the patient with the ITK(R29H) mutant. ITK mutations are distributed over the entire protein and include missense, nonsense and indel mutations, reminiscent of the situation in its sister kinase in B cells, Bruton's tyrosine kinase.

    Full Text Available Abstract Background Markedly elevated IgE as a manifestation of a lymphoproliferative disorder has been only rarely reported. Case Presentation We present the case of a 22 year old female referred to the adult Allergy & Clinical Immunology clinic for an extremely elevated IgE level, eventually diagnosed with Hodgkin's lymphoma. She had no history of atopy, recurrent infections, eczema or periodontal disease; stool was negative for ova & parasites. Chest X-ray revealed large bilateral anterior mediastinal masses that demonstrated prominent uptake on gallium scan. Mediastinal lymph node biopsy was consistent with Hodgkin's lymphoma, nodular sclerosing subtype, grade I/II. Conclusion Although uncommon, markedly elevated IgE may be a manifestation of a malignant process, most notably both Hodgkin's and Non-Hodgkin's lymphomas. This diagnosis should be considered in evaluating an otherwise unexplained elevation of IgE.

    Clinical features of 40 lymphoproliferative neoplasm patients in the setting of systemic autoimmune diseases managed in the Clinic of Hematology during 1994-2006 were analyzed retrospectively. The classification of systemic autoimmune disease patients was as follows: 15 systemic lupus erythematosus--SLE, 11 rheumatoid arthritis--RA, 12 Sjögren's syndrome--SS, 1 scleroderma, and 1 dermatomyositis. Patients comprised 31 women and 9 men of mean age 55 years (range 33-76). Systemic autoimmune diseases preceeded the development of lymphoproliferative neoplasms in 37/40 (92.5%) patients. Mean latency period between the onset of systemic autoimmune diseases and lymphoproliferative neoplasms occurrence was significantly longer in RA (113 months) than in SLE (75 months) and SS patients (65 months)--P autoimmune diseases type or antirheumatic treatment P > 0.05. Our findings are in line with earlier reports showing a high proportion of patients with advanced disease, constitutional symptoms, extranodal manifestations, high grade histology, and low OS in the systemic autoimmune diseases setting.

    British shorthair (BSH) kittens in multiple litters died as a result of a severe non-neoplastic lymphoproliferative disease that showed many similarities with human autoimmune lymphoproliferative syndrome (ALPS). Human ALPS is caused by inherited defects in FAS-mediated lymphocyte apoptosis and the possibility of similar defects was investigated in BSH cats. The whole genomes of two affected kittens were sequenced and compared to 82 existing cat genomes. Both BSH kittens had homozygous insertions of an adenine within exon 3 of the FAS-ligand gene. The resultant frameshift and premature stop codon were predicted to result in a severely truncated protein that is unlikely to be able to activate FAS. Three additional affected BSH kittens were homozygous for the variant, while 11 of 16 unaffected, but closely related, BSH cats were heterozygous for the variant. All BSH cats in the study were from a population with significant inbreeding. The variant was not identified in a further survey of 510 non-BSH cats. Identification of a genetic defect in the FAS-mediated apoptosis pathway confirms that the lymphoproliferative disease in BSH cats fulfills the diagnostic criteria for ALPS in humans. These results will enable the development of a genetic test to detect BSH carrier animals.

    Full Text Available Anti-NMDA receptor (NMDAR encephalitis is a recently identified autoimmune disorder with prominent psychiatric symptoms. Patients usually present with acute behavioral change, psychosis, catatonic symptoms, memory deficits, seizures, dyskinesias, and autonomic instability. In female patients an ovarian teratoma is often identified. We describe a 32-year-old woman who presented with acute psychosis. Shortly after admission, she developed generalized seizures and deteriorated into a catatonic state. Although ancillary tests including MRI, electroencephalogram, and cerebrospinal fluid (CSF analysis were unremarkable, the presentation of acute psychosis in combination with recurrent seizures and a relentless course suggested autoimmune encephalitis. The patient underwent pelvic ultrasound which disclosed a dermoid cyst and which led to an urgent cystectomy. Plasmapheresis was then initiated, yielding partial response over the next two weeks. Following the detection of high titers of anti-NMDAR antibodies in the CSF, the patient ultimately received second line immunosuppressive treatment with rituximab. Over several months of cognitive rehabilitation a profound improvement was eventually noted, although minor anterograde memory deficits remained. In this report we call for attention to the inclusion of anti-NMDAR encephalitis in the differential diagnosis of acute psychosis. Prompt diagnosis is critical as early immunotherapy and tumor removal could dramatically affect outcomes.

    Klinefelter syndrome (KS) is the most common sex chromosomal disorder with an estimated prevalence of 1 in 500-1000. Increased incidences of anxiety, depression, substance abuse, psychotic and behavioral disorders, and sexual disorders have been reported in patients with KS. The aim of this case study was to report a case of a man with untreated KS who was also diagnosed with type II bipolar disorder. This case report raises awareness regarding psychiatric diagnoses that may be associated with such a highly prevalent condition. A 46-year-old man who had previously been diagnosed with an untreated KS was examined in our Psychiatric Department with an acute hypomanic episode. Clinical improvement was observed within 4 days and psychiatric symptoms were resolved in 7 days without use of medication. A psychiatric history of a depressive episode and at least two hypomanic episodes, as well as a family history of two relatives diagnosed with bipolar disorder, strongly suggest that our patient has type II bipolar disorder. Bipolar disorder may be a comorbid disorder in patients with KS. Routine screening for mood disorders and appropriate referral and evaluation should be performed. Future genetic research is warranted to explore why some chromosomal abnormalities (e.g., duplications), especially those located on the X chromosome, such as Klinefelter syndrome, may be associated with a bipolar or psychotic disorder in some individuals but not in others.

    Chronic lymphocytic leukaemia (CLL) is the most frequent form of leukaemia among adults in the Western world, presenting at a median age of 65 years. The diagnosis is usually made incidentally during routine blood examination while the disease is still in its early phase. We report a case of blindness of 24 hours due to acute sinusitis based on CLL localisation in a patient with undiagnosed CLL. Emergency endoscopic sinus surgery and intra- and extra-ocular orbital decompression were performed. The sinusitis resolved after surgery and intravenous antibiotics. Her vision improved within 24 hours and eventually recovered completely after six months. Her CLL remained in an indolent state, needing no active treatment. This case illustrates that blindness from a lymphoproliferative disorder may be treated with emergency endoscopic sinus surgery instead of conventional chemotherapy in order to salvage the vision first, even if the vision is lost for more than 24 hours.

    Full Text Available A 30-year-old female with a history of anxiety, cannabis use, and Avoidant/Restrictive Food Intake Disorder presented for residential treatment of a Cannabis Use Disorder. Upon arrival, she had not eaten for two days and was found to be hypotensive with electrolyte disturbances. She was admitted to a nearby hospital, where the Internist diagnosed her with Addison’s disease. She was treated with corticosteroid therapy, with rapid normalization of her electrolytes, eating, and anxiety. This is the first published case of undiagnosed Addison’s disease presenting as an eating disorder, with cannabis use likely contributing to symptoms. This case elucidates the importance of ruling out other biologic and psychologic causes of clinical presentations before an eating disorder diagnosis can be made.

    Epstein-Barr virus (EBV) is detected in 20% to 30% of sporadic Burkitt lymphoma (sBL). However, only a few studies of EBV-positive (EBV) sBL have been reported, and its characteristics still remain controversial. To highlight the features of EBV sBL, we compared the clinicopathologic characteristics of 33 cases of EBV and 117 cases of EBV-negative (EBV) sBL in Japan. EBV sBL showed significantly higher age distribution (median, 42 vs. 13 y; PEBV group showed significantly higher incidence of involvement of tonsil (P=0.027), adrenal gland (P=0.011), and cervical lymph node (P=0.040). In addition, the EBV group tended to have higher incidence of nodal involvement (P=0.078) and involvement of para-aorta lymph node (P=0.084) and heart (P=0.050). In contrast, the gastrointestinal tract was less frequently affected in EBV sBL (P=0.024). In addition, the less positivity for MUM1 (P=0.020) of EBV sBL was highlighted. These results indicate that biological behavior and pathogenesis of EBV sBL might be different from those of EBV sBL. Our results demonstrate that EBV sBL has an aspect of age-related disease and is a distinct clinicopathologic subtype, which should be distinguished from EBV sBL.

    An elderly woman with a previous diagnosis of atypical chronic lymphocytic leukemia (CLL) was noted to have a strikingly abnormal blood film, with the lymphocytes displaying numerous large cytoplasmic granules. This appearance had not been described before in the literature to the best of the authors' knowledge. After a series of investigations, electron microscopy was eventually performed, which demonstrated that the abnormal granules were composed of immunoglobulin crystals. The immunofixation study confirmed that they were monoclonal IgM paraprotein. These results led to a change of diagnosis to lymphoplasmacytic lymphoma. This report illustrates how electron microscopy can be used as a valuable additional diagnostic tool in difficult cases.

    PTLD is an important post-transplant complication. Although PTLD affects kidney allografts after renal transplantation, it has not been reported in native kidneys of other solid organ recipients. Herein, we report a child who underwent an orthotropic liver transplant for cryptogenic cholestatic hepatitis and developed fever, generalized lymphadenopathy, chronic EBV viremia, and lymphatic PTLD. Subsequently, she also developed gross hematuria and nephrotic range proteinuria. Kidney histology revealed EBV-positive mononuclear infiltrates within the renal parenchyma consistent with PTLD. Electron microscopy examination demonstrated subepithelial electron-dense deposits consistent with a membranous glomerulopathy pattern. The PTLD was successfully treated with reduced immunosuppression and cyclic cyclophosphamide, rituximab, and prednisone, but the renal disease progressed to end-stage renal failure within two yr. Repeat kidney histology showed chronic nephropathy and membranous glomerulopathy without PTLD infiltrates or detectable EBV staining, although chronic viremia persisted. To our knowledge, this is the first such child to be reported and highlights the importance of remaining vigilant for renal PTLD even in non-kidney organ recipients.

    De novo malignancies represent an increasing concern in the transplant population, particularly as long-term graft and patient survival improves. EBV-associated B-cell lymphoma in the setting of PTLD is the leading malignancy in children following solid organ transplantation. Therapeutic strategies can be categorized as pharmacologic, biologic, and cell-based but the variable efficacy of these approaches and the complexity of PTLD suggest that new treatment options are warranted. Here, we review current therapeutic strategies for treatment of PTLD. We also describe the life cycle of EBV, addressing the viral mechanisms that contribute to the genesis and persistence of EBV+ B-cell lymphomas. Specifically, we focus on the oncogenic signaling pathways activated by the EBV LMP1 and LMP2a to understand the underlying mechanisms and mediators of lymphomagenesis with the goal of identifying novel, rational therapeutic targets for the treatment of EBV-associated malignancies.

  19. Diagnostic value of clonality of surface immunoglobulin light and heavy chains in malignant lymphoproliferative disorders.

    1993-08-01

    Cell suspensions from the peripheral blood of B-chronic lymphoid leukemias (B-CLL, n = 274) and reactive lymphocytosis (RLC, n = 132) and from solid tissue samples of B-non-Hodgkin's lymphoma (B-NHL, n = 466) and reactive lymphadenopathy (RLA, n = 324) were analyzed to evaluate the diagnostic value of clonality of L- and H- chains in B-CLL and B-NHL. Cutoff levels for monoclonal L-chain (mono-L) and monoclonal H-chain (mono-H) were defined. In B-CLL, the association patterns of L- and H- chains were as follows: mono-L/mono-H, 245 cases (89.42%); mono-L/polyclonal H chain (poly-H), 4 (1.46%); polyclonal L chain (poly-L)/mono-H, 2 (0.73%); poly-L/poly-H, 2 (0.73%); undetected (und)-L/mono-H, 6 (2.19%); and und-L/und-H, 15 (5.47%). In B-NHL, the association patterns were mono-L/mono-H, 433 cases (92.92%); mono-L/poly-H, 4 (0.86%); poly-L/mono-H, 8 (1.72%); poly-L/poly-H, 2 (0.43%); und-L/mono-H, 4 (0.86%); and und-L/und-H, 15 (3.22%). Monoclonality of H chains are complementary to L-chain restriction, especially in the cases with poly-L or und-L, and should be considered as a positive criterion in determining surface immunoglobulin (SIg) clonality. Monoclonality of SIg assessed by both L and H chains is both sensitive and specific for the diagnosis of B-CLL and B-NHL, and their differentiation from RLC and RLA, since none of the cases of RLC and RLA showed monoclonal SIg.

    Castleman disease (CD), a benign lymphoproliferative disorder that affects lymph nodes, is uncommon in children, with only approximately 100 cases published. Although 23% of pediatric CD cases are found in the neck, there is no substantial reported percentage found in the salivary glands, especially the submandibular salivary gland (SMSG). A pediatric case of CD involving the SMSG is reported because of its extreme rarity. Copyright © 2016 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

    Chromosomal microarray analysis is now commonly used in clinical practice to identify copy number variants (CNVs) in the human genome. We report our experience with the use of the 105 K and 180K oligonucleotide microarrays in 215 consecutive patients referred with either autism or autism spectrum disorders (ASD) or developmental delay/learning disability for genetic services at the University of Kansas Medical Center during the past 4 years (2009-2012). Of the 215 patients [140 males and 75 females (male/female ratio=1.87); 65 with ASD and 150 with learning disability], abnormal microarray results were seen in 45 individuals (21%) with a total of 49 CNVs. Of these findings, 32 represented a known diagnostic CNV contributing to the clinical presentation and 17 represented non-diagnostic CNVs (variants of unknown significance). Thirteen patients with ASD had a total of 14 CNVs, 6 CNVs recognized as diagnostic and 8 as non-diagnostic. The most common chromosome involved in the ASD group was chromosome 15. For those with a learning disability, 32 patients had a total of 35 CNVs. Twenty-six of the 35 CNVs were classified as a known diagnostic CNV, usually a deletion (n=20). Nine CNVs were classified as an unknown non-diagnostic CNV, usually a duplication (n=8). For the learning disability subgroup, chromosomes 2 and 22 were most involved. Thirteen out of 65 patients (20%) with ASD had a CNV compared with 32 out of 150 patients (21%) with a learning disability. The frequency of chromosomal microarray abnormalities compared by subject group or gender was not statistically different. A higher percentage of individuals with a learning disability had clinical findings of seizures, dysmorphic features and microcephaly, but not statistically significant. While both groups contained more males than females, a significantly higher percentage of males were present in the ASD group.

    Autoimmune lymphoproliferative syndrome (ALPS) is associated with mutations that impair the activity of lymphocyte apoptosis proteins, leading to chronic lymphadenopathy, hepatosplenomegaly, autoimmunity, and an increased risk of lymphoma. We investigated the utility of fluorodeoxyglucose positron emission tomography (FDG-PET) in discriminating benign from malignant lymphadenopathy in ALPS. We report that FDG avidity of benign lymph nodes in ALPS can be high and, hence, by itself does not imply presence of lymphoma; but FDG-PET can help guide the decision for selecting which of many enlarged nodes in ALPS patients to biopsy when lymphoma is suspected.

    Patients with active lymphoproliferative diseases (LPD) were shown to have high activity of lymphocyte uroporphyrinogen synthase (L-UROS), the enzyme which converts porphobilinogen to uroporphyrinogen. The mean L-UROS activity of 64 first-degree relatives of patients with LPD was significantly higher than that of a control group and 45% of these relatives had pathological values of L-UROS. L-UROS activity was also determined in the spouses of 2 patients and was pathologically elevated in both. The pattern of pathological values among family members may indicate the presence of a communicable agent.

    Niemann-Pick disease type C (NPC) is a rare progressive neurodegenerative disorder, often with onset after normal early childhood development. Juvenile onset NPC patients slowly develop cerebellar symptoms and cognitive impairment and often experience difficulties at school. However, these problems may be overlooked due to the unpublicized nature of NPC, given that it is a rare metabolic disorder. In this report, we present an 11-year-old male NPC patient, who suffered from clumsiness and dif...

    The International Society for the Study of Personality Disorders (ISSPD) celebrated its 25th anniversary in September 2013 in Copenhagen and commemorated the First International Congress at the same site. The overall theme of the congress was "Bridging Personality and Psychopathology: The Person Behind the Illness." More than 400 abstracts were submitted, and the program included 8 keynote presentations, 18 invited symposia, a debate on current controversial issues in the classification of personality disorders (Fossati, Tyrer, Livesley, and Krueger), an ISSPD award lecture (Silk), a jubilee lecture (Simonsen), a young researchers' symposium (Hopwood, Sharp, and Kaess), and special lectures on the Danish philosopher Soeren Kierkegaard and the poet Hans Christian Andersen. In this article we will survey the presentations and highlight the important issues in order to underline the current trends in research and clinical interests in personality disorders. The keynote video presentations, invited symposia, and slide presentations are freely available at www.isspd2013.com.

    Anorexia nervosa (AN) and bulimia nervosa (BN) are marked by longitudinal symptom fluctuations. DSM-IV-TR does not address how to classify eating disorder (ED) presentations in individuals who no longer meet full criteria for these disorders. To consider this issue, we examined subthreshold presentations in women with initial diagnoses of AN and BN. A total of 246 women with AN or BN were followed for a median of 9 years; weekly symptom data were collected at frequent intervals using the Longitudinal Interval Follow-up Evaluation of Eating Disorders (LIFE-EAT-II). Outcomes were ED presentations that were subthreshold for 3 months, including those narrowly missing full criteria for AN or BN, along with binge eating disorder (BED) and purging disorder. During follow-up, most women (77.6%) experienced a subthreshold presentation. Subthreshold presentation was related to intake diagnosis (Wald chi2=8.065, df=2, p=0.018). Individuals with AN most often developed subthreshold presentations resembling AN; those with BN were more likely to develop subthreshold BN. Purging disorder was experienced by half of those with BN and one-quarter of those with AN binge/purge type (ANBP); BED occurred in 20% with BN. Transition from AN or BN to most subthreshold types was associated with improved psychosocial functioning (p<0.001). Subthreshold presentations in women with lifetime AN and BN were common, resembled the initial diagnosis, and were associated with modest improvements in psychosocial functioning. For most with lifetime AN and BN, subthreshold presentations seem to represent part of the course of illness and to fit within the original AN or BN diagnosis.

    Full Text Available We describe a 14-year-old girl, who was 13 y after liver transplantation for biliary atresia with an unremarkable postoperative course. She presented with fever of up to 40°C, extreme fatigue, malaise, anorexia, and occasional vomiting. On physical examination the only finding was splenomegaly. Lab results showed hyperglobulinemia and an elevated sedimentation rate. Liver function tests were normal except for mild elevation of γGTP. Abdominal U/S and CT demonstrated an enlarged spleen with retroperitoneal and mesenteric lymph nodes enlargement. An exhaustive evaluation for infectious causes, autoimmune conditions, and malignancy was negative. A full recovery after 5 months prompted testing for self-limited infectious etiologies. Yersinia enterocolitica infection was diagnosed.

    Post-transplant lymphoproliferative disease (PTLD) is a rare and serious complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT) or solid organ transplantation. We conducted a retrospective analysis of the occurrence of post-transplant lymphoproliferative disease in allo-HSCT recipients over 12 years in a single center in China. A total of 343 patients received allo-HSCT. The conditioning therapy consisted of a busulfan/cyclophosphamide-based regimen, a fludarabine/cyclophosphamide-based regimen, or total-body irradiation and cyclophosphamide. In transplantations from unrelated donors and haplo-identical donors, patients also received antithymocyte globulin (ATG) or thymoglobulin as part of the conditioning. Five of the 343 patients (1.46%) were diagnosed with PTLD and all 5 were given ATG as part of conditioning. Among these 5 patients, 4 had lymphoid neoplasm before transplantation. EBV-positivity was confirmed in 4 patients. All 5 PTLD patients received reduction of immunosuppression (RI) as fundamental therapy. At follow-up on April 1, 2013, 1 patient had survived for 2 years and 1 had survived for 9 years. The correlation of PTLD with ATG and underlying diseases were examined by statistical analysis using the chi-squared test or Fisher's exact test (P=0.011 and 0.025, respectively). Although only 1.46% of patients progressed to PTLD associated with ATG and underlying diseases, the mortality was still high. Moreover, RI can be an effective therapy for PTLD patients, but other approaches should be further explored.

    2013-03-01

    The mucopolysaccharide disorders (MPS) are a group of recessively inherited metabolic disorders resulting in progressive physical and cognitive decline. MEDLINE, PsycINFO and Embase databases were searched, alongside manual screening, to identify relevant literature. Papers were included in the review if they were published in a peer reviewed journal and conducted empirical research into cognitive, motor, social or linguistic development or behaviour in one or more MPS disorders. Twenty-five papers were reviewed. Two papers used methodology of a sufficiently high standard to demonstrate a behavioural phenotype; both found sleep disturbance to be part of the phenotype of MPS III. Fearfulness and sleep disturbance were frequently observed in people with MPS I and II. Cognitive and motor impairment and decline, and challenging behaviour were highly prevalent in the severe form of MPS II. Cognitive decline and severe behavioural problems relating to aggression, hyperactivity, orality, unusual affect and temper tantrums were seen in MPS III. Sleep disturbance is part of the behavioural phenotype of MPS III, and challenging behaviour is highly prevalent in MPS II and MPS III, therefore the efficacy of behavioural interventions for these populations should be investigated. Further research into the behaviour and adaptive skills of children with MPS III and MPS IV is required.

    Facial trauma in sports has been associated with temporomandibular disorders. Because of the intensity and duration of training needed for elite-level competitions, high-performance athletes can have two to five times more traumatic injuries than recreational athletes. This study aimed to investigate the prevalence of temporomandibular disorders in high-performance martial arts fighters and compare it with the prevalence in recreational athletes and non-athletes. The Research Diagnostic Criteria for Temporomandibular Disorders was used to diagnose and classify professional karate-do practitioners (group I; n = 24), amateur karate-do practitioners (group II; n = 17), high-performance mixed martial arts fighters (group III; n = 13), and non-athletes (n = 28). The groups were compared with the chi-square test and tested for the difference between two proportions using a significance level of 5% (P 0.05). A diagnosis of arthralgia from disk displacement was made more frequently in groups I (45.8%; P = 0.013) and III (38.5%; P = 0.012) than in group IV (7.1%). The chronic pain associated with TMD was low intensity and low disability. While there was a high prevalence of temporomandibular disorders in the professional athletes in our study, the prevalence of the condition in recreational athletes was similar to that in individuals who did not practice martial arts. © 2015 John Wiley & Sons A/S.

    Obsessive-compulsive disorder (OCD) is a frequent and severe disease, potentially inducing a major impairment for the patient and burden for their family. Recent research in psychiatry and neuroscience have led to better comprehension of the disease's mechanisms and helped to improve its treatment. However, a large proportion of patients have refractory symptoms, including for traditional cognitive and behavioral therapy by exposure and response prevention (ERP), leading clinicians to look for new treatments. Mindfulness-based interventions (MBI) are a new type of approach, initially based on Buddhist meditation, which aims to provide better consciousness of the present moment. It has been successfully developed in some psychiatric diseases and other general medical conditions such as chronic pain. The two main programs using mindfulness meditation, Mindfulness-based stress reduction (MBSR) and Mindfulness-based cognitive therapy (MBCT), have shown effectiveness for the reduction of depressive and anxiety symptoms and relapses of depressive episodes in unipolar depression. It has no side effects and is well tolerated by patients. Its action relies on the specific correction of cognitive deficits in attention, emotion regulation and executive functions which are shared by OCD, GAD and depression. For OCD, we make the hypothesis that Mindfulness-Based Interventions could reduce the cognitive bias specifically existing in this pathology, such as dysfunctional beliefs, and therefore improve the symptoms. This article first reviews the existing literature on clinical trials involving Mindfulness-Based Interventions in OCD which comprises a small number of clinical studies based on very different types of protocols. At this time, and due to the lack of gold-standard studies with a large number of patients, no proof of the efficiency of mindfulness-based interventions in OCD has been shown. In a second section, following our hypothesis on the mechanisms of specific and

    Despite several polysomnographic normative studies and multiple surveys of sleep disorders in the general population, few data have been collected on healthy sleepers. We aimed to survey the characteristics of healthy sleep. We prospectively investigated the sleep history of 100 subjects of a representative population sample who reported undisturbed sleep and in whom relevant sleep disorders were ruled out by a two-step screening procedure. Approximately four subjects had to be contacted for identifying 1 eligible subject who participated. The median reported time in bed was from 23:00 (21:30-02:00) to 07:00 (05:30-11:00). The total sleep duration was 7.3 h (5-10 h), varying from 7.5 h in the age group ≤ 30 years to 7 h in subjects aged 40-60 years and to 8 h in subjects > 60 years (p = 0.002). The median sleep efficiency was high (93.3%, range: 55.6% to 100%). Fifty-one subjects reported occasional snoring. Forty-five subjects reported sporadic non-bothersome sleep-related movement disorders (25 sleep-related leg cramps, 22 lifetime bruxism, 5 restless legs syndrome), and 36 had a history of sporadic non-bothersome parasomnias (27 nightmares, 12 sleepwalking, 1 sleep paralysis). In this population of healthy sleepers, snoring is the most common finding. Moreover, non-bothersome forms of recognizable sleep-related movement disorders and parasomnias are surprisingly common. These findings may suggest that diagnostic criteria of sleep disorders should not only be based on the presence of symptoms but also account for a minimum frequency or discomfort.

    To delineate the relative roles of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and Fas ligand in lymphocyte biology and lymphoproliferative disease, we generated mice defective in both molecules. B6.GT mice develop severe polyclonal lymphoproliferative disease because of accumulating CD3(+)CD4(-)CD8(-)B220(+) T cells, CD4(+) and CD8(+) T cells, and follicular B cells, and mice die prematurely from extreme lymphocytosis, thrombocytopenia, and hemorrhage. Accumulating lymphocytes resembled antigen-experienced lymphocytes, consistent with the maximal resistance of B6.GT CD4(+) and CD8(+) T cell to activation-induced cell death. More specifically, we show that TRAIL contributes to Fas ligand-mediated activation-induced cell death and controls lymphocyte apoptosis in the presence of interferon-gamma once antigen stimulation is removed. Furthermore, dysregulated lymphocyte homeostasis results in the production of anti-DNA and rheumatoid factor autoantibodies, as well as antiplatelet IgM and IgG causing thrombocytopenia. Thus, B6.GT mice reveal new roles for TRAIL in lymphocyte homeostasis and autoimmune lymphoproliferative syndromes and are a model of spontaneous idiopathic thrombocytopenia purpura secondary to lymphoproliferative disease.

    X-linked lymphoproliferative disease (XLP) is a primary immunodeficiency characterized by extreme susceptibility to Epstein-Barr virus. The XLP disease gene product SH2D1A (SAP) interacts via its SH2 domain with a motif (TIYXXV) present in the cytoplasmic tail of the cell-surface receptors CD150/SLAM, CD84, CD229/Ly-9, and CD244/2B4. Characteristically, the SH2D1A three-pronged interaction with Tyr(281) of CD150 can occur in absence of phosphorylation. Here we analyze the effect of SH2D1A protein missense mutations identified in 10 XLP families. Two sets of mutants were found: (i) mutants with a marked decreased protein half-life (e.g. Y7C, S28R, Q99P, P101L, V102G, and X129R) and (ii) mutants with structural changes that differently affect the interaction with the four receptors. In the second group, mutations that disrupt the interaction between the SH2D1A hydrophobic cleft and Val +3 of its binding motif (e.g. T68I) and mutations that interfere with the SH2D1A phosphotyrosine-binding pocket (e.g. C42W) abrogated SH2D1A binding to all four receptors. Surprisingly, a mutation in SH2D1A able to interfere with Thr -2 of the CD150 binding motif (mutant T53I) severely impaired non-phosphotyrosine interactions while preserving unaffected the binding of SH2D1A to phosphorylated CD150. Mutant T53I, however, did not bind to CD229 and CD224, suggesting that SH2D1A controls several critical signaling pathways in T and natural killer cells. Because no correlation is present between identified types of mutations and XLP patient clinical presentation, additional unidentified genetic or environmental factors must play a strong role in XLP disease manifestations.

    This study aimed to: (a) examine parental socio-demographic factors in children and adolescents referred to an outpatient service for internalizing and externalizing disorders, and (b) compare the demographic variables and diagnoses for the two diagnostic groups. Parents of all children who were referred to the child and adolescent outpatient service were asked to participate. Following their informed consent, they completed a socio-demographic questionnaire for themselves and a Child Behaviour Checklist (CBCL) for their child. The CBCL scores and the diagnoses assigned by the psychiatrists were then recorded for each child. Diagnoses were classified as internalizing or externalizing based on the primary DSM-IV diagnosis assigned by the psychiatrists. Data for the two groups were compared for study variables using Pearson correlation, t-tests, one-way ANOVA and logistic regression. Children who had externalizing disorders tended to live with unemployed single parents who had lower education levels and lived in rented or assisted housing. Children with internalizing problems tended to live in owned homes with employed parents. There was no significant association between age or gender for either group. Previous literature has reported an association between low SES and more mental health problems; however, the relationship between different indicators of SES and diagnosis is not clear. Despite small numbers, our study revealed significant differences between the parental socio-demographic factors for externalizing compared with internalizing disorders.

    Epstein-Barr virus (EBV) is associated with several malignancies, including post-transplant lymphoproliferative disorder (PTLD). Conventional treatments for PTLD are often successful, but risk organ rejection and cause significant side effects. EBV-specific cytotoxic T lymphocytes (CTLs) generated in vitro from peripheral blood lymphocytes provide an alternative treatment modality with few side effects, but autologous CTLs are difficult to use in clinical practice. Here we report the establishment and operation of a bank of EBV-specific CTLs derived from 25 blood donors with human leucocyte antigen (HLA) types found at high frequency in European populations. Since licensure, there have been enquiries about 37 patients, who shared a median of three class I and two class II HLA types with these donors. Cells have been infused into ten patients with lymphoproliferative disease, eight of whom achieved complete remission. Neither patient with refractory disease was matched for HLA class II. Both cases of EBV-associated non-haematopoietic sarcoma receiving cells failed to achieve complete remission. Thirteen patients died before any cells could be issued, emphasizing that the bank should be contacted before patients become pre-terminal. Thus, this third party donor-derived EBV-specific CTL cell bank can supply most patients with appropriately matched cells and most recipients have good outcomes.

Medication-taking self-efficacy, which is the confidence that one can take one's medication as prescribed, is associated with better adherence with HIV medication. However, little is known about the influence that other kinds of self-efficacy have on adherence with HIV medication, especially among HIV-infected individuals with co-occurring substance use and/or mood disorders. We sought to examine the relationship between adherence with HIV medication among substance users and three specific kinds of self-efficacy, ie, one's confidence that one can communicate with medical providers, get support, and manage one's mood. We further sought to examine whether symptoms of depression and anxiety moderate these relationships.Methods: Patients were recruited from three HIV clinics in the southeastern United States as part of an integrated study of treatment for HIV and substance use.Results: We interviewed 154 patients with HIV and substance use who reported taking HIV medications. Based on symptoms of depression and anxiety using the Patient Health Questionnaire-9 and the Hospital Anxiety and Depression Scale-Anxiety, 63% had probable depression and/or anxiety.

    This paper offers research case studies of four severely maltreated children who had received a diagnosis of autistic spectrum disorder. A range of measures were employed to explore the children's psychological and emotional functioning, including Theory of Mind assessment (Sally-Anne Test), attachment measures (Story Stems Assessment Profile and Relationship Problems Questionnaire), along with measures to assess general psychological and emotional well-being. Contrary to the diagnosis, the children did not reveal a theory of mind deficit. However, they did indicate a profile of difficulties in mentalisation on the Story Stems. The findings are discussed in terms of the extent to which mentalisation and theory of mind are influenced by situational factors, especially the anxiety evoked by the Story Stem attachment scenarios. Clinical implications regarding mentalisation as a state vs. trait phenomenon are discussed.

    Full Text Available Niemann-Pick disease type C (NPC is a rare progressive neurodegenerative disorder, often with onset after normal early childhood development. Juvenile onset NPC patients slowly develop cerebellar symptoms and cognitive impairment and often experience difficulties at school. However, these problems may be overlooked due to the unpublicized nature of NPC, given that it is a rare metabolic disorder. In this report, we present an 11-year-old male NPC patient, who suffered from clumsiness and difficulties in attention and academic and social skills. His symptoms were initially considered to be due to developmental coordination disorder (DCD coexisting with bullying by peers. DCD is a type of neurodevelopmental disorder defined according to DSM-IV and is characterized by clumsiness that interferes with academic achievement and social integration not due to other general medical conditions. However, a detailed investigation of the patient suggested that the problems could be attributed to the onset of NPC. Clinicians should keep neurodegenerative disorders as differential diagnosis of children with multiple school problems.

    Full Text Available Attention-Deficit/Hyperactivity Disorder (ADHD is a neurodevelopmental disorder increasing in prevalence. Although there is limited evidence to support treating ADHD with mineral/vitamin supplements, research does exist showing that patients with ADHD may have reduced levels of vitamin D, zinc, ferritin, and magnesium. These nutrients have important roles in neurologic function, including involvement in neurotransmitter synthesis. The aim of this paper is to discuss the role of each of these nutrients in the brain, the possible altered levels of these nutrients in patients with ADHD, possible reasons for a differential level in children with ADHD, and safety and effect of supplementation. With this knowledge, clinicians may choose in certain patients at high risk of deficiency, to screen for possible deficiencies of magnesium, vitamin D, zinc, and iron by checking RBC-magnesium, 25-OH vitamin D, serum/plasma zinc, and ferritin. Although children with ADHD may be more likely to have lower levels of vitamin D, zinc, magnesium, and iron, it cannot be stated that these lower levels caused ADHD. However, supplementing areas of deficiency may be a safe and justified intervention.

    Enteric disorders are an important cause of economic losses in broiler chickens worldwide. Several agents have been associated with enteric problems, such as viruses, bacteria, and parasites. In this study, broiler chickens showing signs of enteric disorders were subjected to molecular diagnosis for several viral agents and also for pathological examination for elucidating this problem. Thus, the chickens were screened for avian nephritis virus (ANV), chicken astrovirus (CAstV), avian rotavirus (ArtV), avian reovirus (AReoV), infectious bronchitis virus (IBV), fowl adenovirus group I (FAdV-1), and chicken parvovirus (ChPV). Postmortem examinations revealed a curving of the duodenal loop (J-like appearance) and intestines filled with liquid and gaseous content. Histopathological analysis of the duodenal loop showed pancreatic atrophy, acute mesenteritis, and enteritis. PCR results showed that ChPV was the sole viral agent detected in samples with lesions such as the curved duodenal loop and pancreatic atrophy. Molecular characterization of the nucleotide and deduced amino acid sequences revealed a high similarity with other strains of ChPV from Brazil, Canada, United States, Europe, and Asia. These findings suggest an association between ChPV and the development of enteritis, pancreatitis, and pancreatic atrophy, which may lead to curling of the duodenal loop. Together, these alterations may disrupt the normal functioning of the digestive system, diminishing digestion and the absorption of dietary nutrients and consequently leading to reduced weight gain, flock impairment, dwarfism, and an elevated feed conversion rate.

    Full Text Available Abstract Background Screening for mental disorders among disability claimants is important, since mental disorders seem to be seriously under-recognized in this population. However, performance of potentially suitable scales is unknown. We aimed to evaluate the psychometric properties of three scales, the 10- and 6-item Kessler Psychological Distress Scale (K10, K6 and the 12-item General Health Questionnaire (GHQ-12, to predict present state mental disorders, classified according to the Diagnostic and Statistical Manual of Mental Disorders, 4thEdition (DSM-IV among disability claimants. Methods All scales were completed by a representative sample of persons claiming disability benefit after two years sickness absence (n=293. All diagnoses, both somatic and mental, were included. The gold standard was the Composite International Diagnostic Interview (CIDI 3.0 to diagnose present state DSM-IV disorder. Cronbach’s α, sensitivity, specificity, positive (PPV and negative predictive values (NPV, and the areas under the Receiver Operating Characteristic curve (AUC were calculated. Results Cronbach’s alpha’s were 0.919 (K10, 0.882 (K6 and 0.906 (GHQ-12. The optimal cut-off scores were 24 (K10, 14 ( K6 and 20 (GHQ-12.

The AUC’s for 30-day cases were 0.806 (K10; 95% CI 0.749-0.862, 0.796 (K6; 95% CI 0.737-0.854 and 0.695 (GHQ-12; 95% CI 0.626-0.765. Conclusions The K10 and K6 are reliable and valid scales to screen for present state DSM-IV mental disorder. The optimal cut-off scores are 24 (K10 and 14 (K6. The GHQ-12 (optimal cut-off score: 20 is outperformed by the K10 and K6, which are to be preferred above the GHQ-12.

    In order to delineate the specific morphological and immunophenotypic features of B-cell lymphoproliferative disorders associated with trisomy 12, 172 sequential unselected cases of CD19+CD5+ B-cell disorders, primarily affecting the peripheral blood and bone marrow, were studied. Trisomy 12 was found in 24 cases (13.9%), with all cases morphologically classified as either CLL-PL or CLL-mixed by FAB criteria. Trisomy 12 was not found in any cases of typical CLL. Trisomy 12 cases demonstrated a significant higher expression of CD11a (P<0.0001) and CD20 (P<0.0006) when compared to cases with the equivalent morphology and immunophenotype, but without the chromosomal abnormality. Trisomy 12 cases also demonstrated a higher frequency of FMC7, CD38 expression and moderate to strong surface immunoglobulin staining. However, no correlation was detected between the percentages of trisomy 12 cells and cells expressing CD11a, CD38, FMC7 or sIg mean fluorescent intensity. Cells from trisomy 12 positive cases were sorted according to their CD11a expression using fluorescent activated cell sorting. There was a significant increase in the percentage of trisomy 12 cells within the CD11a+ sorted fraction compared to the unsorted population (P < 0.05), implying that trisomy 12 is associated with increased expression of CD11a. With the highly specific morphological and immunophenotypic features demonstrated by trisomy 12 cases in this study, it is highly likely that these cases constitute a specific group of B-cell lymphoproliferative disorders.

    Multivisceral transplantation represents an important treatment option for children with intestinal failure. The attendant immunosuppression can lead to a spectrum of cellular proliferations including benign and malignant smooth muscle tumors and lymphoproliferative disorders, many related to cellular dysregulation from Epstein-Barr virus infection. The purpose of this study is to investigate the rates of post-transplantation proliferative disorders among children with multivisceral transplantation and to characterize the imaging and pathological features of these disorders. We identified all consecutive children who underwent multivisceral transplant from August 2004 to October 2011 with at least 27 months of clinical and imaging follow-up. We reviewed medical records to determine the underlying causes of the multivisceral transplant, age at transplantation, onset of neoplasm development, and outcome. Two pediatric radiologists reviewed all imaging studies independently and diagnosis of disease was made by consensus interpretation. Pathological specimens were reviewed for histopathological findings of post-transplantation neoplasm in this pediatric patient population. The study population consisted of 14 consecutive pediatric patients (7 boys and 7 girls; mean age 26 months, range 4-113 months). Of these 14 children, 4 (29%) developed histologically confirmed post-transplant neoplasms at a mean time of 2.4 years after multivisceral transplantation. Types of neoplasms included post-transplant lymphoproliferative disorder (PTLD) in three (21%) and Epstein-Barr-virus-associated smooth muscle tumor in two (14%). (One child developed both neoplasms following transplantation). Both children with smooth muscle tumor associated with Epstein-Barr virus presented with characteristic hypointense solid masses with peripheral rim enhancement on cross-sectional imaging studies. The mortality rate of children who developed post-transplant neoplasms was higher than that of those

    We report a child with short stature since birth who was otherwise well, presenting at 2.8 years with progressive granulomatous skin lesions when diagnosed with severe T cell immunodeficiency. When previously investigated for short stature, and at the time of current investigations, she had no radiological skeletal features characteristics for cartilage hair hypoplasia, but we found a disease causing RMRP (RNase mitochondrial RNA processing endoribonuclease) gene mutation. Whilst search for HLA matched unrelated donor for haematopoietic stem cell transplantation (HSCT) was underway, she developed rapidly progressive EBV-related lymphoproliferative disorder requiring laparotomy and small bowel resection, and was treated with anti-B cell monoclonal antibody and eventually curative allogeneic HSCT. Screening for RMRP gene mutations should be part of immunological evaluation of patients with 'severe and/or combined' T cell immunodeficiency of unknown origin, especially when associated with short stature and regardless of presence or absence of radiological skeletal features.

    In childhood, central nervous system (CNS) presentations associated with antibodies to voltage-gated potassium channel (VGKC) complex include limbic encephalitis, status epilepticus, epileptic encephalopathy, and autistic regression. We report the cases of two individuals (a 6-year-old male and an 11-year-old female) who presented with an acute-onset explosive seizure disorder with positive VGKC complex antibodies and bilateral basal ganglia changes on magnetic resonance imaging (MRI). Both patients made a complete clinical recovery, without immunotherapy, with resolution of the MRI changes and normalization of the antibody levels. Extended antibody testing, including testing for leucine-rich glioma-inactivated 1 (LGI1), contactin-associated protein 2, and contactin-2 was negative. This could suggest that the clinico-radiological phenotype in our patients may in fact be associated with a novel autoreactive target(s) within the VGKC complex, as may be the case in other children with VGKC complex-mediated CNS disorders.

    Full Text Available Abstract Background: Autoimmune lymphoproliferative syndrome (ALPS is a disorder of lymphocyte homeostasis and immunological tolerance due primarily to genetic defects in Fas (CD95/APO-1; TNFRSF6, a cell surface receptor that regulates apoptosis and its signaling apparatus. Methods: Fas ligand gene mutations from ALPS patients were identified through cDNA and genomic DNA sequencing. Molecular and biochemical assessment of these mutant Fas ligand proteins were carried out by expressing the mutant FasL cDNA in mammalian cells and analysis its effects on Fas-mediated programmed cell death. Results: We found an ALPS patient that harbored a heterozygous A530G mutation in the FasL gene that replaced Arg with Gly at position 156 in the protein's extracellular Fas-binding region. This produced a dominant-interfering FasL protein that bound to the wild-type FasL protein and prevented it from effectively inducing apoptosis. Conclusion: Our data explain how a naturally occurring heterozygous human FasL mutation can dominantly interfere with normal FasL apoptotic function and lead to an ALPS phenotype, designated Type Ib.

    Autoimmune lymphoproliferative syndrome (ALPS) is a disorder of lymphocyte apoptosis characterized by non-malignant lymphadenopathy and splenomegaly, expansion of T cells without either CD4 or CD8 surface markers, and increased incidence of autoimmune diseases and lymphoma. Most patients with ALPS have dominant, heterozygous mutations in tumor necrosis factor receptor superfamily member 6 (TNFRSF6), which encodes CD95, also known as Fas, a mediator of apoptosis. Penetrance and range of disease manifestations in ALPS are highly variable, even among family members who share the same dominant TNFRSF6 mutation. To evaluate HLA as a candidate modifier locus, we typed HLA A, B (including subtypes), and DQB alleles in 356 individuals from 63 unrelated families with defined TNFRSF6 mutations associated with ALPS. We also developed a quantitative severity score and performed statistical analysis. Among the healthier, mutation-bearing individuals, transmission of HLA B44 was significantly overrepresented (nominal PALPS. The B44 allele may exert a protective role in ALPS.

    Children with autism spectrum disorder (ASD) may require interventions for communication difficulties. One type of intervention is picture communication symbols which are proposed to improve comprehension of linguistic input for children with ASD. However, atypical attention to faces and objects is widely reported across the autism spectrum for several types of stimuli. In this study we used eye-tracking methodology to explore fixation duration and time taken to fixate on the object and face areas within picture communication symbols. Twenty-one children with ASD were compared with typically developing matched groups. Children with ASD were shown to have similar fixation patterns on face and object areas compared with typically developing matched groups. It is proposed that children with ASD attend to the images in a manner that does not differentiate them from typically developing individuals. Therefore children with and without autism have the same opportunity to encode the available information. We discuss what this may imply for interventions using picture symbols. © 2013 The Authors.

    We have analyzed the relationships between personality traits and the quality of life in 95 in-patients with motor function disorders undergoing the rehabilitative treatment. It was shown that the high quality of life in the patients suffering from motor function disorders as a result of an acute cerebral circulation disorder correlated with the positive attitudes towards recovering and stress resistance. In the patients presenting with degenerative-dystrophic diseases of the joints, the high quality of life correlated with the purpose-oriented behaviour and discipline expressed as the commitment to the goal. It was suggested based on the results of the study that the correction of the level of situational and trait anxiety should be regarded as the main end-point of the psychological treatment of the patients with acute cerebral circulation disorders, while the patients suffering from degenerative-dystrophic diseases of the joints could benefit from education designed to enhance compliance to the treatment and motivation for recovery.

    Over the past 5 years, a great deal of information about the early course of autism spectrum disorder (ASD) has emerged from longitudinal prospective studies of infants at high risk for developing ASD based on a previously diagnosed older sibling. The current article describes early ASD symptom presentations and outlines the rationale for defining a new disorder, Early Atypical Autism Spectrum Disorder (EA-ASD) to accompany ASD in the new revision of the ZERO TO THREE Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC:0-5) (in press) alternative diagnostic classification manual. EA-ASD is designed to identify children who are 9 to 36 months of age presenting with a minimum of (a) two social-communication symptoms and (b) one repetitive and restricted behavior symptom as well as (c) evidence of impairment, with the intention of providing these children with appropriately tailored services and improving the likelihood of optimizing their development. © 2016 Michigan Association for Infant Mental Health.

    Castleman's disease (CD) is a heterogeneous lymphoproliferative disorder of unknown aetiology. Mostly, this disorder is seen in immunocompromised hosts. It is known to be associated with systemic disorders like HIV, HHV-8, lymphoma, and Kaposi sarcoma. As of today, the clinical behaviour and outcome of CD in immunocompetent host remains suboptimally studied. We analyzed consecutively treated cases of CD presented to our centre in last 12 years. Case record files were studied for patient's characteristics, clinical presentation, baseline laboratory and pathologic parameters, therapy and outcome. This study describes presentation and treatment outcome of CD in immunocompetent patients. Total 16 patients of CD were treated during the study period. The median age of patients at the time of presentation was 40.5 years (range 13-72 years). An equal number of patients (8 each) had unicentric and multicentric CD. Sixty-three percent patients had hyaline vascular subtype while 37 % patients had plasma cell or mixed variant. Majority of the patients had good performance status (ECOG PS 0, 1 in 10 (62.5 %) patients; PS2-4 in 6 (37.5 %) patients). The median duration of symptoms was 6 months (range 2-36 months). None of the patients in our study had associated HIV infection. Six patients presented with fever, out of which four had plasma cell variant of CD and three of them had multicentric involvement. In comparison to unicentric CD, patients with multicentric CD had lower albumin levels (4.15 vs. 3.38 g/dl, p = 0.006), haemoglobin levels (11.3 vs. 9.8, p = 0.06), and lower complete remission rates (62.5 % vs. none). Patients were treated according to the stage and clinical status with surgery, chemotherapy or combination of both modalities. Surgery was the predominant treatment for unicentric CD while multicentric CD was treated with various chemotherapy regimens. Eight patients were treated with chemotherapy (CHOP-based regimen-5, melphalan

    . Consequently, the goal of the study was to investigate sleep problems in medicine-naive school-aged children (mean age = 9.6 years) with ADHD compared to controls using objective methods and to examine the role of comorbidity and presentations. Ambulatory polysomnography results suggested that children......-group differences were found on the multiple sleep latency test. Stratifying for comorbidity in the ADHD group did not reveal major differences between groups, but mean sleep latency was significantly longer in children with ADHD and no comorbidity compared to controls (36.1 min; SD = 30.1 versus 22.6 min; SD = 15.......2). No differences were found between ADHD presentations. Our results support the presence of night-time sleep disturbances in children with ADHD. Poor sleep does not appear to be attributable to comorbidity alone, nor do sleep disturbances differ within ADHD presentations....

    Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a clinically heterogeneous disorder characterized by epileptic seizures, psychosis, dyskinesia, consciousness impairments, and autonomic instability. Symptoms are always various. Sometimes it presents in milder or incomplete forms. We report 4 cases of anti-NMDAR encephalitis with incomplete forms, 3 cases of which were accompanied by neuromyelitis optica spectrum disorder or neurosyphilis respectively. A 33-year-old man presented with dysarthria, movement disorder and occasional seizures. He had 6 relapses in 28 years. When suffered from upper respiratory tract syndrome, he developed behavioral and consciousness impairment. Cranial MRI was normal. Viral PCR studies and oncologic work-up were negative. Anti-NMDAR antibody was detected in CSF and serum. A 21-year-old female manifested dizziness and diplopia ten months and six months before, respectively. Both responded to steroid therapy and improved completely. This time she presented with progressive left limb and facial anesthesia, walking and holding unsteadily. Spinal cord MRI follow-up showed abnormality of medulla oblongata and cervical cord(C1). Anti-AQP4 and anti-NMDAR were positive in CSF. Steroid-pulse therapy ameliorated her symptoms. A 37-year-old male experienced worsening vision. He was confirmed neurosyphilis since the CSF tests for syphilis were positive. Protein was elevated and the oligoclonal IgG bands(OB) and anti-NMDAR was positive in CSF. Anti-aquaporin 4(AQP4) antibodies and NMO-IgG were negative. Cranial MRI showed high FLAIR signal on frontal lobe and low T2 signal adjacent to the right cornu posterious ventriculi lateralis. Treatment for neurosyphlis was commenced with gradual improvement. A 39-year-old male, developed serious behavioral and psychiatric symptoms. Examination showed abnormal pupils and unsteady gait. He was confirmed neurosyphilis according to the CSF tests for syphilis. Anti-NMDAR was positive in CSF and serum

    We reported 19 cases of school-aged children. They were initially judged to have learning difficulty or school maladaptation because of attention deficits, hyperactive behaviors or poor school performance, followed by the diagnosis such as degenerative or metabolic neurological diseases. The patients consisted of 4 cases of adrenoleukodystrophy, 5 cases of dentatorubral-pallidoluysian atrophy, 3 cases of Sanfilippo syndrome, 3 cases of subacute sclerosing panencephalitis, and each one case of juvenile Gaucher disease, juvenile Huntington disease, juvenile metachromatic leukodystrophy and Leigh disease. They had markedly poor school performance, and/or abnormal behaviors, followed by seizures, character disorders or psychomotor regression. The diagnostic clues included brain CT scan and/or MRI, peculiar facial appearance and notable family histories. When the children were indicated to have learning difficulty or maladjustment to school life, we should make deliberate differential diagnoses before concluding that they have a learning disorder and/or attention-deficit/hyperactivity disorder. Instead they should be recommended to visit child neurologists, when they present with any problems as aforesaid.

    Full Text Available Lymphoproliferative disease virus (LPDV is a poorly understood, oncogenic avian retrovirus of domestic turkeys that has historically been restricted to Europe and Israel. However, a recent study reported LPDV in multiple wild turkey diagnostic cases from throughout the eastern United States of America (USA. To better understand the distribution of LPDV in the eastern USA, we surveyed 1,164 reportedly asymptomatic hunter-harvested wild turkeys from 17 states for the presence of LPDV proviral DNA by PCR. In total, 564/1,164 (47% turkeys were positive for LPDV. Wild turkeys from each state had a relatively high prevalence of LPDV, although statewide prevalence varied from 26 to 83%. Phylogenetic analysis revealed two major clades of LPDV in the USA, although one was at a low frequency suggesting restricted transmission, as well as significant clustering by state of isolation. To determine the best tissue to target for diagnostic purposes, liver, spleen, and bone marrow were tested from a subset of 15 hunter-harvested wild turkeys and 20 wild turkey diagnostic cases. Overall, bone marrow provided the highest level of detection for both hunter-harvested turkeys and diagnostic cases. The sensitivity of LPDV detection between tissues was not significantly different for diagnostic cases, but was for hunter-harvested birds. These results indicate that LPDV infection is common and widespread in wild turkey populations throughout the eastern USA, even without overt signs of disease.

    Lymphoproliferative disease virus (LPDV) is a retrovirus that infects wild and domestic turkeys ( Meleagris gallopavo ). The first cases of LPDV in the United States were diagnosed in 2009, and subsequent surveillance has revealed the virus to be widespread in wild turkey populations throughout the eastern half of the country. More research is needed to determine whether LPDV is having a negative effect on turkey populations, but progress has been impeded by the lack of a simple method for diagnosing the virus in living birds. Infected animals may appear asymptomatic, and diagnostics currently rely on tissue or bone marrow, which can be difficult to obtain. This study investigated the reliability of polymerase chain reaction (PCR) to detect LPDV in whole blood, compared with previous methods using buffy coat (concentrated white blood cells) and bone marrow. Paired samples of whole blood and buffy coat were collected from 137 live turkeys and paired samples of whole blood and bone marrow were collected from 32 turkeys postmortem. Compared with buffy coat, whole blood had 97% sensitivity and 100% specificity. When compared with bone marrow, whole blood had 100% sensitivity and 89% specificity. Both comparisons had a high degree of agreement using Cohen's kappa statistic. Based on these results, PCR of whole blood provides detection of LPDV in living birds that is on par with both buffy coat and bone marrow.

    Autoimmune diseases develop in approximately 5% of humans. They can arise when self-tolerance checkpoints of the immune system are bypassed as a consequence of inherited mutations of key genes involved in lymphocyte activation, survival, or death. For example, autoimmune lymphoproliferative syndrome (ALPS) results from defects in self-tolerance checkpoints as a consequence of mutations in the death receptor-encoding gene TNF receptor superfamily, member 6 (TNFRSF6; also known as FAS). However, some mutation carriers remain asymptomatic throughout life. We have now demonstrated in 7 ALPS patients that the disease develops as a consequence of an inherited TNFRSF6 heterozygous mutation combined with a somatic genetic event in the second TNFRSF6 allele. Analysis of the patients' CD4(-)CD8(-) (double negative) T cells--accumulation of which is a hallmark of ALPS--revealed that in these cells, 3 patients had somatic mutations in their second TNFRSF6 allele, while 4 patients had loss of heterozygosity by telomeric uniparental disomy of chromosome 10. This observation provides the molecular bases of a nonmalignant autoimmune disease development in humans and may shed light on the mechanism underlying the occurrence of other autoimmune diseases.

  14. An Appropriate Modulation of Lymphoproliferative Response and Cytokine Release as Possible Contributors to Longevity

    2017-01-01

    The decrease in the proliferative response of lymphocytes is one of the most evident among the age-related changes of the immune system. This has been linked to a higher risk of mortality in both humans and experimental animals. However, long-lived individuals, in spite of optimally maintaining most of the functions of the immune system, also seem to show an impaired proliferative response. Thus, it was hypothesized that these individuals may have distinct evolution times in this proliferation and a different modulatory capacity through their cytokine release profiles. An individualized longitudinal study was performed on female ICR-CD1 mice, starting at the adult age (40 weeks old), analyzing the proliferation of peritoneal leukocytes at different ages in both basal conditions and in the presence of the mitogen Concanavalin A, for 4, 24 and 48 h of culture. The cytokine secretions (IL-2, IL-17, IL-1β, IL-6, TNF-α and IL-10) in the same cultures were also studied. Long-lived mice show a high proliferative capacity after short incubation times and, despite experiencing a functional decline when they are old, are able to compensate this decrease with an appropriate modulation of the lymphoproliferative response and cytokine release. This could explain their elevated resistance to infections and high longevity. PMID:28737707

    Mutations in the IL-2-inducible T-cell kinase gene have recently been shown to cause an autosomal recessive fatal Epstein Barr virus (EBV) associated lymphoproliferation. We report 3 cases from a single family who presented with EBV-positive B-cell proliferation diagnosed as Hodgkin's lymphoma. Single nucleotide polymorphism array-based genome-wide linkage analysis revealed IL-2-inducible T-cell kinase as a candidate gene for this disorder. All 3 patients harbored the same novel homozygous nonsense mutation C1764G which causes a premature stop-codon in the kinase domain. All cases were initially treated with chemotherapy. One patient remains in durable remission, the second patient subsequently developed severe hemophagocytic lymphohistiocytosis with multi-organ failure and died, and the third patient underwent a successful allogeneic bone marrow transplantation. IL-2-inducible T-cell kinase deficiency underlies a new primary immune deficiency which may account for part of the spectrum of Epstein Barr virus related lymphoproliferative disorders which can be successfully corrected by bone marrow transplantation.

    Clostridium difficile infection (CDI) is an increasingly problem in everyday clinical practice. The most important risk factor of this infection is antibiotics use. The incidence of Clostridium difficile associated diarrhea (CDAD) in patients after renal transplantation is estimated to be about 6% in the early postoperative period. Due to the applied immunosuppression and frequent infections requiring intensive, broad spectral antibiotics, the later prevalence of CDAD may remain at a similar level. Massive diarrhea caused by Clostridium difficile may lead to fluctuations in immunosuppressive drugs concentration, in renal transplant patients. The authors present a case study of a 23-year old patient after kidney transplantation from deceased donor, with diagnosed polymorphic PTLD (Post-Transplant Lymphoproliferative Disorder). During biological treatment with rituximab in this patient 4 recurrences of CDI were observed. In this article the clinical manifestation of recurrent CDAD are presented. The authors discuss therapeutic procedure with fidaxomicin use, its results and influence on immunosuppressive drugs concentration.

    Full Text Available Abstract Introduction Intracranial or spinal compressive lesions due to extramedullary hematopoiesis have been reported in the medical literature. Most of the reported cases are extradural lesions or, on rare occasions, foci within another neoplasm such as hemangioblastoma, meningioma or pilocytic astrocytoma. Often these cases occur in patients with an underlying hematological disorder such as acute myelogenic leukemia, myelofibrosis, or other myelodysplastic syndromes. Such lesions have also been reported in thalassemia major. Case presentation We report the case of a 43-year-old Iranian woman in whom extramedullary hematopoiesis presented as a compressive cord lesion and then later as an intracranial lesion. Conclusions To the best of our knowledge, we document the first reported case of sacral, lumbar, thoracic and cranial involvement in the same patient with extramedullary hematopoiesis, which seems both rare and remarkable.

    Full Text Available Dendritic cells (DCs and monocytes are critical regulators and effectors of innate and adaptive immune responses. Monocyte expansion has been described in many pathological states while monocyte and DC deficiency syndromes are relatively recent additions to the catalogue of human primary immunodeficiency disorders. Clinically applicable screening tests to diagnose and monitor these conditions are lacking. Conventional strategies for identifying human DCs and monocytes have been based on the use of a lineage gate to exclude lymphocytes, thus preventing simultaneous detection of DCs, monocytes and lymphocyte subsets. Here we demonstrate that CD4 is a reliable lineage marker for the human peripheral blood antigen presenting cell compartment that can be used to identify DCs and monocytes in parallel with lymphocytes. Based on this principle, simple modification of a standard lymphocyte phenotyping assay permits simultaneous enumeration of four lymphocyte and five DC/monocyte populations from a single sample. This approach is applicable to clinical samples and facilitates the diagnosis of DC and monocyte disorders in a wide range of clinical settings, including genetic deficiency, neoplasia and inflammation.

    Although previously considered a disorder of childhood, studies in the last decade have demonstrated that attention-deficit hyperactivity disorder (ADHD) continues to impair function into adulthood and responds to pharmacotherapy. Due to age-specific changes in roles and challenges, it is possible that presentation and response to intervention may differ between older and younger adults. A literature search for papers that identified older adults with ADHD, including papers describing its epidemiology, manifestation, and treatment, was the basis for this paper. There is a paucity of data on ADHD in older adults; however, small observational studies have characterized the presence, impact, and treatment of ADHD in adults over the age of 50 years, and larger epidemiologic studies have demonstrated that ADHD symptoms exist in older adulthood. Optimal criteria for diagnosis of ADHD and methods of treating ADHD in older individuals have not been systematically explored. In light of the limited data, this review discusses considerations for differential diagnosis and safe pharmacotherapy of ADHD in older adults.

    We present a clinimetric assessment of the Movement Disorder Society (MDS)-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS). The MDS-UDPRS Task Force revised and expanded the UPDRS using recommendations from a published critique. The MDS-UPDRS has four parts, namely, I: Non-motor Experiences of Daily Living; II: Motor Experiences of Daily Living; III: Motor Examination; IV: Motor Complications. Twenty questions are completed by the patient/caregiver. Item-specific instructions and an appendix of complementary additional scales are provided. Movement disorder specialists and study coordinators administered the UPDRS (55 items) and MDS-UPDRS (65 items) to 877 English speaking (78% non-Latino Caucasian) patients with Parkinson's disease from 39 sites. We compared the two scales using correlative techniques and factor analysis. The MDS-UPDRS showed high internal consistency (Cronbach's alpha = 0.79-0.93 across parts) and correlated with the original UPDRS (rho = 0.96). MDS-UPDRS across-part correlations ranged from 0.22 to 0.66. Reliable factor structures for each part were obtained (comparative fit index > 0.90 for each part), which support the use of sum scores for each part in preference to a total score of all parts. The combined clinimetric results of this study support the validity of the MDS-UPDRS for rating PD.

    To explore the relationship between innate immunity and hepatitis C Virus (HCV) in determining the risk of cirrhosis (CIR), hepatocellular carcinoma (HCC), mixed cryoglobulinemia syndrome (MCS) and non-Hodgkin lymphoma (NHL), we investigated the impact of the toll-like receptor-2 (TLR2) and interleukin-28B (IL28B) genetic variants. TLR2 -174 del variant was associated with TLR2 expression and with specific downstream molecules that drive the expression of different interleukins; rs12979860 Il28B was important in response to interferon-treatment and in spontaneous clearance of HCV. The risk for liver and lymphoproliferative diseases in HCV progression was clarified by stratifying 862 HCV-positive patients into groups based on liver (CIR, HCC) and lymphoproliferative HCV-related diseases (MCS, NHL) and compared with chronic HCV (CHC) infection. Analysis of TLR2-IL28B haplotypes showed an association of wild type haplotype with the lymphoproliferative diseases (OR 1.77, p = 0.029) and a slight increase in HCV viral load (HR 1.38, p = 0.054). Wild type haplotype (TLR2 ins/ins- IL28B C/C) was also found associated with older age in patients with an hepatic diseases (in CIR and in HCC p = 0.038 and p = 0.020, respectively) supporting an effect of innate immunity in the liver disease progression. TLR2 and IL28B polymorphisms in combination showed a role in the control of HCV viral load and different HCV disease progression.

    Full Text Available Primitive neuroectodermal tumor (PNET/ewing′s sarcoma is a rare neural crest tumor of central nervous system, thoracopulmonary regions, pelvis, and lower extremities. Visceral involvement by PNET is a rare phenomenon, with kidney being the most commonly involved organ. We report a 35-year-old Asian female presenting with left inguinal swelling, with computed tomography scan evidence of conglomerate lymph nodal mass in the left external iliac and inguinal region. A clinico-radiological diagnosis of lymphoproliferative disorder was made. She subsequently underwent excision biopsy. Histopathology of the biopsy specimen revealed completely effaced lymph nodal architecture, which was replaced by a tumor composed of nests of small, round, blue cells. On immunohistochemistry, the tumor cells were positive for CD99 and negative for CD3, CD20, leucocyte common antigen, epithelial membrane antigen, cytokeratin, desmin, vimentin, synaptophysin, and chromogranin A. Extensive search regarding any possible different site of involvement by the tumor was negative. The clinical presentation and histological, cytological, and immunohistochemical pattern, lead to the diagnosis of metastatic PNET of the left external iliac and inguinal lymph node with unknown primary origin. To the best of our knowledge, it is the first ever reported case of inguinal lymphadenopathy as the solitary metastatic presentation of PNET of unknown origin.

    Full Text Available Three cases of Epstein-Barr virus (EBV-negative post-transplant lymphoproliferative disease that occurred 6 to 8 years after renal transplantation are reported. The patients respectively had gastric mucosa-associated lymphoid tissue lymphoma, gastric diffuse large B-cell lymphoma, and atypical Burkitt lymphoma. Absence of EBV in the tissue samples was demonstrated by both in situ hybridization for EBV early RNA and polymerase chain reaction for EBV DNA. Patients were treated with reduction in immunosuppression and combined chemotherapy plus an anti-CD20 monoclonal antibody, rituximab. Despite the reduction in immunosuppression, patients had stable renal functions without loss of graft functions. The patient with atypical Burkitt lymphoma had an abnormal karyotype, did not respond to treatment completely, and died due to disease progression. The other patients are still alive and in remission 5 and 3 years after diagnosis, respectively. EBV-negative post-transplant lymphoproliferative diseases are usually late-onset and are reported to have poor prognosis. Thus, reduction in immunosuppression is usually not sufficient for treatment and more aggressive approaches like rituximab with combined chemotherapy are required.

    Epstein–Barr virus (EBV) has been associated with a variety of epithelial and hematologic malignancies, including B-, T- and NK cell-lymphomas, Hodgkin's disease (HD), post-transplant lymphoproliferative diseases (LPDs), nasopharyngeal and gastric carcinomas, smooth muscle tumors, and HIV-associated lymphomas. Currently, treatment options for EBV-associated malignancies are limited. We have previously shown that myxoma virus specifically targets various human solid tumors and leukemia cells in a variety of animal models, while sparing normal human or murine tissues. Since transplant recipients of bone marrow or solid organs often develop EBV-associated post-transplant LPDs and lymphoma, myxoma virus may be of utility to prevent EBV-associated malignancies in immunocompromised transplant patients where treatment options are frequently limited. In this report, we demonstrate the safety and efficacy of myxoma virus purging as a prophylactic strategy for preventing post-transplant EBV-transformed human lymphomas, using a highly immunosuppressed mouse xenotransplantation model. This provides support for developing myxoma virus as a potential oncolytic therapy for preventing EBV-associated LPDs following transplantation of bone marrow or solid organ allografts. - Highlights: • Myxoma virus effectively infects and purges EBV lymphoma cells in vivo. • Oncolytic myxoma virus effectively eradicates oncogenic EBV tumorigenesis. • Ex vivo pre-treatment of myxoma virus can be effective as a preventive treatment modality for post-transplant lymphoproliferative diseases.

    In developing countries like Bangladesh, delayed presentation for disorders of sex development (DSD) is common, and provides some special problems for management. There remains significant controversy about appropriate sex assignment in this group. We aimed, therefore, to assess gender identity (GI) in 50 consecutive patients with DSD presenting to a referral centre in Chittagong, Bangladesh, and correlate it with Prader score, to see if the latter could be used to predict GI. A cross-sectional, case-control study of 50 consecutive children with DSD and 50 children with vascular anomalies was conducted in the Pediatric Surgical Clinic, Chittagong Medical College and Hospital. After informed consent, patients and controls provided oral answers to a GI questionnaire and had a detailed history and physical examination. Sex-typed activities were assessed by observations of a structured toy play and the child's selection of a toy to keep. Both patients and parents then completed the Child Game Participation Questionnaire. There were no differences in age (2-16 years, mean 8.74) between controls and DSD patients (11 46, XX DSD, 32 46, XY DSD, 4 MGD, 3 ovo-testicular DSD). Fifteen of the DSD patients (30 %) came from consanguineous marriages and only 2 of the control patients had consanguinity of their parents. For the 13-question GI interview, there was no overall difference between DSD cases and controls. For the 46, XX DSD subgroup, there was a significantly higher score (11.1 ± 7.1) compared with control girls (4.5 ± 4.7) (p gender-related behaviour correlated with Prader score for DSD patients (r = 0.61) (p gender-role behaviour should be assessed routinely in DSD patients presenting after the neonatal period, so that sex assignment is in accordance with behaviour. Prader scores showed a good correlation with GI and gender role behaviour.

    We report 2 cases of renal transplant recipients in whom hepatosplenic gamma-delta T-cell lymphoma (gamma-delta HSTCL) developed 5 and 10 years after transplantation. Both patients had marked hepatosplenomegaly, B symptoms (weight loss, fever, and night sweats), and abnormal peripheral blood findings, including anemia in both, thrombocytopenia and leukoerythroblastic changes in 1, and leukocytosis in the other. Markedly atypical lymphoid infiltrate of intermediate to large cells was observed in the spleen, liver, and bone marrow. The malignant cells showed typical immunophenotype of gamma-delta T cells (CD2+, CD3+, CD4-, CD8-, CD7+, gamma-delta T-cell receptor-positive, and alpha-beta T-cell receptor-negative) with clonal T-cell receptor gene rearrangement and were of the V-delta-1 subset. In addition, the cells contained a cytolytic granule-associated protein, TIA-1, and Fas ligand, indicating cytotoxic T-cell differentiation. The malignant T cells in both cases were of host tissue origin. Both cases were negative for Epstein-Barr virus genome using Southern blot analysis. The patients did not respond to reduction of immunosuppression. Despite initial response to chemotherapy, both patients died within 6 months of diagnosis. Our findings indicate that gamma-delta HSTCL can occur as a late complication in transplant recipients.

    A 39-year-old male underwent a nonmyeloablative stem cell transplant (NMAPBPCT) from his HLA-matched sister for recurrent anaplastic large cell lymphoma in CR-2, receiving fludarabine, cyclophosphamide, and rabbit antithymocyte globulin for the preparative therapy. The patient was readmitted on day+33 for persistent culture-negative fevers. He rapidly developed marked elevations of alkaline phosphatase and bilirubin. Liver biopsy showed a periportal infiltrate of large immunoblastic appearing cells. The tumor cells did not stain for CD3/CD20/CD30 and alk protein, but did stain for CD79a/LCA and CD43. In situ hybridization for Epstein-Barr virus (EBV) RNA (EBER 1) was strongly positive in the periportal infiltrating lymphocytes. Fluorescence in situ hybridization (FISH) studies revealed female (XX) cells in the tumor cells and male (XY) in the surrounding hepatic parenchymal cells. The patient developed severe lactic acidosis, oliguric renal failure and expired on day+44. Both donor and patient had positive IgG serologies for EBV VCA and EBNA pretransplant. The donor also had a positive IgM titer for EBV VCA in the pretransplant specimen. The LPD may have been related to the intense immunosuppression of the preparative therapy and the presence of recent EBV infection in the donor.

    A total of 20 patients with cold antibody hemolytic anemia were evaluated in a retrospective study of them, 15 had a monoclonal gammopathy of unknown significance (MGUS): 14 with MGUS of immunoglobulin M (IgM) subtype and 1 with immunoglobulin G subtype. One patient had smoldering Waldenström's macroglobulinemia, but four patients had no monoclonal protein and no evidence of lymphoma. However, in three of these patients, we were able to demonstrate a (mono-)clonal rearrangement of their immunoglobulin heavy and/or light chains. Of the 20 patients, 5 had IgHV34 nucleotide sequence indicating that the antibody was directed against the "I" antigen. Two patients exhibited a progressive increase of IgM over time, however without increasing hemolytic activity. Moreover, in two patients with long-term follow-up, we were able to correlate recurrent hemolytic activity with low environmental temperatures. Among four patients treated with rituximab, all four responded to treatment. However, treatment effect was only transient in all of them.

    Full Text Available Dissociative identity disorder (DID is one of the most fascinating disorders in psychiatry. The arduous search to reveal the obscurity of this disorder has led to colossal research in this area over the years. Although drug-assisted interviews are not widely used, they may be beneficial for some patients that do not respond to conventional treatments such as supportive psychotherapy or psychopharmacotherapy. Drug-assisted interviews facilitate recall of memories in promoting integration of dissociative information. We report a case of a 16-year-old female with dissociative identity disorder (DID that was treated with lorazepam-assisted interview and there was rapid improvement in symptoms after the interview.

    Understanding the prevalence and type of personality disorder within prison systems allows for the effective targeting of resources to implement strategies to alleviate symptoms, manage behaviour and attempt to reduce re-offending. This study aimed to determine the prevalence of personality disorder (PD) traits within a local urban high-turnover adult male prison with a remand/recently sentenced population in London, UK. The International Personality Disorder Examination - Screening Questionnaire (IPDE-SQ) self-administered questionnaire (ICD-10 version) was completed by 283 prisoners (42% completion rate). 77% of respondents reached the threshold for one or more PDs. The most common PD types were Paranoid PD (44.5%), Anankastic PD (40.3%), Schizoid PD (35%) and Dissocial PD (25.8%). These results confirm and extend existing knowledge regarding the prevalence of PD in prison populations into a high-turnover, urban, remand population. The stark comparison with community samples indicates that a more equitable standard of service delivery within the criminal justice system, focussing on preventive and early intervention services, is now required.

  20. Childhood sarcoidosis: A rare but fascinating disorder

    Full Text Available Abstract Childhood sarcoidosis is a rare multisystemic granulomatous disorder of unknown etiology. In the pediatric series reported from the southeastern United States, sarcoidosis had a higher incidence among African Americans. Most reported childhood cases have occurred in patients aged 13–15 years. Macrophages bearing an increased expression of major histocompatibility class (MHC II molecules most likely initiate the inflammatory response of sarcoidosis by presenting an unidentified antigen to CD4+ Th (helper-inducer lymphocytes. A persistent, poorly degradable antigen driven cell-mediated immune response leads to a cytokine cascade, to granuloma formation, and eventually to fibrosis. Frequently observed immunologic features include depression of cutaneous delayed-type hypersensitivity and a heightened helper T cell type 1 (Th1 immune response at sites of disease. Circulating immune complexes, along with signs of B cell hyperactivity, may also be found. The clinical presentation can vary greatly depending upon the organs involved and age of the patient. Two distinct forms of sarcoidosis exist in children. Older children usually present with a multisystem disease similar to the adult manifestations, with frequent hilar lymphadenopathy and pulmonary infiltrations. Early-onset sarcoidosis is a unique form of the disease characterized by the triad of rash, uveitis, and arthritis in children presenting before four years of age. The diagnosis of sarcoidosis is confirmed by demonstrating a typical noncaseating granuloma on a biopsy specimen. Other granulmatous diseases should be reasonably excluded. The current therapy of choice for sarcoidosis in children with multisystem involvement is oral corticosteroids. Methotrexate given orally in low doses has been effective, safe and steroid sparing in some patients. Alternative immunosuppressive agents, such as azathioprine, cyclophosphamide, chlorambucil, and cyclosporine, have been tried in adult cases

    However, HCV interferes with cytokines at various levels and escapes immune response by inducing a T-helper (Th2/T cytotoxic 2 cytokine profile. Inability to control infection leads to the recruitment of inflammatory infiltrates into the liver parenchyma by interferon (IFN-gamma-inducible CXC chemokine ligand (CXCL-9, -10, and -11 chemokines, which results in sustained liver damage and eventually in liver cirrhosis. The most important systemic HCV-related extrahepatic diseases—mixed cryoglobulinemia, lymphoproliferative disorders, thyroid autoimmune disorders, and type 2 diabetes—are associated with a complex dysregulation of the cytokine/chemokine network, involving proinflammatory and Th1 chemokines. The therapeutical administration of cytokines such as IFN-alpha may result in viral clearance during persistent infection and reverts this process.

    BACKGROUND Intravascular lymphoma (IVL) is a rare lymphoproliferative disorder characterized by the proliferation of large B lymphoma cells within the lumen of small-caliber blood vessels. Clinical features are nonspecific, presenting as a systemic disease with fever and may be life-threatening. Antemortem diagnosis is difficult but may be made with biopsies of affected tissues or with random skin biopsies. CASE REPORT We report the case of a 66-year-old white woman presenting with fever of unknown origin (FUO) who developed neurologic, pulmonary, and hematologic manifestations. The diagnosis of intravascular large B cell lymphoma (IVLBCL) was made by random skin biopsies. She received treatment with steroids, rituximab, cyclophosphamide, vincristine, and doxorubicin (R-CHOP). Her disease evolution was unfavorable and she died after her first cycle of chemotherapy. CONCLUSIONS Our case illustrates that IVL can present as FUO and should be considered in the differential diagnosis of this syndrome, especially in patients with neurologic compromise and persistently elevated serum lactate dehydrogenase. In this case, the diagnosis was made with cutaneous biopsies of visibly unaffected skin. As in our patient, the course of IVL is usually fatal within a few months.

    Epstein-Barr virus (EBV) has been associated with a variety of epithelial and hematologic malignancies, including B-, T- and NK cell-lymphomas, Hodgkin's disease (HD), post-transplant lymphoproliferative diseases (LPDs), nasopharyngeal and gastric carcinomas, smooth muscle tumors, and HIV-associated lymphomas. Currently, treatment options for EBV-associated malignancies are limited. We have previously shown that myxoma virus specifically targets various human solid tumors and leukemia cells in a variety of animal models, while sparing normal human or murine tissues. Since transplant recipients of bone marrow or solid organs often develop EBV-associated post-transplant LPDs and lymphoma, myxoma virus may be of utility to prevent EBV-associated malignancies in immunocompromised transplant patients where treatment options are frequently limited. In this report, we demonstrate the safety and efficacy of myxoma virus purging as a prophylactic strategy for preventing post-transplant EBV-transformed human lymphomas, using a highly immunosuppressed mouse xenotransplantation model. This provides support for developing myxoma virus as a potential oncolytic therapy for preventing EBV-associated LPDs following transplantation of bone marrow or solid organ allografts.

    We report a case of intestinal indolent T-cell lymphoproliferative disease (TCLPD) occurring after the initiation of tumor necrosis factor-α (TNF-α) inhibitor therapy for resistant Crohn's disease. A prominent T-cell infiltrate positive for CD8, TIA-1, and T-cell receptor-βF1 was associated with the foci of active inflammation. T-cell receptor gene clonality studies (BIOMED-2) demonstrated monoclonality. After the TNF-α inhibitor treatment was withdrawn, the T-cell infiltrates regressed, but 2 years later, the same monoclonal T-cell infiltrate reappeared at the only site of active inflammation. To the best of our knowledge, this report is the first to show a link between active inflammation and the TCLPD. In addition, it suggests a possible influence of the TNF-α inhibitor treatment on the evolution of the TCLPD. A high degree of suspicion is required in the presence of any unusual lymphoid infiltrate in inflammatory bowel disease to avoid overlooking an indolent TCLPD or misdiagnose an aggressive lymphoma.

    X-linked lymphoproliferative disease (XLP1) arises from mutations in the gene encoding SLAM-associated protein (SAP) and leads to abnormalities of NKT-cell development, NK-cell cytotoxicity, and T-dependent humoral function. Curative treatment is limited to allogeneic hematopoietic stem cell (HSC) transplantation. We tested whether HSC gene therapy could correct the multilineage defects seen in SAP(-/-) mice. SAP(-/-) murine HSCs were transduced with lentiviral vectors containing either SAP or reporter gene before transplantation into irradiated recipients. NKT-cell development was significantly higher and NK-cell cytotoxicity restored to wild-type levels in mice receiving the SAP vector in comparison to control mice. Baseline immunoglobulin levels were significantly increased and T-dependent humoral responses to NP-CGG, including germinal center formation, were restored in SAP-transduced mice.We demonstrate for the first time that HSC gene transfer corrects the cellular and humoral defects in SAP(-/-) mice providing proof of concept for gene therapy in XLP1.

    Full Text Available Background: Children with developmental coordination disorder (DCD lack motor coordination and have difficulty performing motor skills and activities of daily living. Research shows these children do not outgrow their motor difficulties and without intervention do not improve. Physiotherapy is relevant for these children, but due to limited clinical protocols for DCD the aim of this study was to determine the effect of a gross motor training programme for 6–12-year-old children with DCD.Methods: This randomised pre-test, post-test study recruited 64 children with scores of 15th percentile or below using the Movement Assessment Battery for Children (M-ABC. The children were divided equally into an intervention group receiving 8 weeks of gross motor training for core stability, strengthening exercises, balance and coordination with task-specific activities for 30 min per week, while the control group continued with general therapy and activities of daily living. The M-ABC and Developmental Coordination Disorder Questionnaire (DCDQ were used to assess each child before and after 8 weeks.Results: Sixty children completed the study, with 43 males and 17 females (mean age 10.02 years, SD = 2.10. There were no adverse reactions to the programme and M-ABC scores for the intervention programme improved by 6.46%, ball skills (3.54% and balance (4.80% compared with the control (0.17% and (0.15%, respectively. There were significant (p < 0.05 improvements in DCDQ scores, but teachers allocated lower scores than parents.Conclusion: This study supports 8 weeks of gross motor training which can be a beneficial intervention for physiotherapists to improve gross motor function for DCD.Keywords: Developmental, co-ordination, skills, motor

    Human T-cell lymphotropic virus (HTLV)-1 was the first human retrovirus to be associated to cancer, namely adult T-cell leukemia (ATL), but its pathogenesis remains enigmatic, since only a minority of infected individuals develops either ATL or the neuroinflammatory disorder HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). A functional FAS -670 polymorphism in an interferon (IFN)-regulated STAT1-binding site has been associated to both ATL and HAM/TSP susceptibility. Fashi T stem cell memory (Tscm) cells have been identified as the hierarchical apex of ATL, but have not been investigated in HAM/TSP. In addition, both FAS and STAT1 have been identified in an IFN-inducible HAM/TSP gene signature, but its pathobiological significance remains unclear. We comprehensively explored Fas expression (protein/mRNA) and function in lymphocyte activation, apoptosis, proliferation, and transcriptome, in PBMC from a total of 47 HAM/TSP patients, 40 asymptomatic HTLV-1-infected individuals (AC), and 58 HTLV-1 -uninfected healthy controls. Fas surface expression followed a two-step increase from HC to AC and from AC to HAM/TSP. In HAM/TSP, Fas levels correlated positively to lymphocyte activation markers, but negatively to age of onset, linking Fashi cells to earlier, more aggressive disease. Surprisingly, increased lymphocyte Fas expression in HAM/TSP was linked to decreased apoptosis and increased lymphoproliferation upon in vitro culture, but not to proviral load. This Fashi phenotype is HAM/TSP-specific, since both ex vivo and in vitro Fas expression was increased as compared to multiple sclerosis (MS), another neuroinflammatory disorder. To elucidate the molecular mechanism underlying non-apoptotic Fas signaling in HAM/TSP, we combined transcriptome analysis with functional assays, i.e., blocking vs. triggering Fas receptor in vitro with antagonist and agonist-, anti-Fas mAb, respectively. Treatment with agonist anti-Fas mAb restored apoptosis, indicating

    2009-03-01

    Full Text Available For the past few years more and more new cytotoxic agents active in the treatment of hematological malignancies have been synthesized and become available for either in vitro studies or clinical trials. Among them the class of antineoplastic drugs belonging to the purine nucleoside analogues group (PNAs plays an important role. Three of them: pentostatin (DCF, cladribine (2-CdA and fludarabine (FA were approved by Food and Drug Administration (FDA for the treatment of hematological malignancies. Recently three novel PNAs: clofarabine (CAFdA, nelarabine (ara-G and forodesine (immucillin H, BCX-1777 have been synthesized and introduced into preclinical studies and clinical trials. These agents seem to be useful mainly for the treatment of human T-cell proliferative disorders and they are currently undergoing clinical trials in lymphoid malignancies. However, there are also several studies suggesting the role of these drugs in B-cell malignancies. This review will summarize current knowledge concerning the mechanism of action, pharmacologic properties, clinical activity and toxicity of PNAs accepted for use in clinical practice, as well as new agents available for clinical trials.

    Chemokine ligand-receptor interactions play a pivotal role in cell attraction and cellular trafficking, both in normal tissue homeostasis and in disease. In cancer, chemokine receptor-4 (CXCR4) expression is an adverse prognostic factor. Early clinical studies suggest that targeting CXCR4 with suitable high-affinity antagonists might be a novel means for therapy. In addition to the preclinical evaluation of [(68)Ga]Pentixafor in mice bearing human lymphoma xenografts as an exemplary CXCR4-expressing tumor entity, we report on the first clinical applications of [(68)Ga]Pentixafor-Positron Emission Tomography as a powerful method for CXCR4 imaging in cancer patients. [(68)Ga]Pentixafor binds with high affinity and selectivity to human CXCR4 and exhibits a favorable dosimetry. [(68)Ga]Pentixafor-PET provides images with excellent specificity and contrast. This non-invasive imaging technology for quantitative assessment of CXCR4 expression allows to further elucidate the role of CXCR4/CXCL12 ligand interaction in the pathogenesis and treatment of cancer, cardiovascular diseases and autoimmune and inflammatory disorders.

    Epstein-Barr virus-positive T-cell lymphoproliferative diseases (EBV-T-LPDs) are rare lymphomas with poor prognosis. Although chemotherapeutic strategies such as CHOP have been often selected, they have exhibited only limited efficacy. To clarify the mechanism of chemoresistance, we examined P-glycoprotein (P-gp) expression. P-gp acts as an energy-dependent efflux pump that excretes drugs from the cytoplasm, resulting in low-intracellular drug concentrations and poor sensitivity to chemotherapy. We examined P-gp expression in EBV-positive cells by immunohistochemistry staining in three patients of EBV-T-LPDs and the expression was detected in all patients. We also examined mdr1 mRNA expression by reverse-transcriptase polymerase-chain reaction (RT-PCR) in EBV-positive tumor cells from these patients and additional three patients. The expression was detected in all examined patients. In five EBV-T-LPDs patients, P-gp function was detected by Rhodamine-123 efflux assay in these cells. The efflux was inhibited by treatment with a P-gp inhibitor, cyclosporine A (CsA). We also examined and detected P-gp expression in EBV-positive T-cell lines SNT8 and SNT16 established from EBV-T-LPDs patients, by RT-PCR and western blotting. The function was also detected by Rhodamine-123 efflux in these cell lines. Inhibition and knock down of P-gp by CsA and siRNA, respectively, enhanced etoposide- and doxorubicin-induced cell death in the EBV-positive T-cell lines. Finally, we infected the T-cell line MOLT4 with EBV, and found that mdr1 mRNA expression and Rhodamine 123 efflux were upregulated after infection. These results indicated that enhanced P-gp expression contributed to the chemoresistance of EBV-T-LPDs.

    Used in this paper is the material secured in the examination of 82 children aged 11 to 14 years old presenting with thyroidal dysfunction, who had come from ecologically abnormal zones and placed on a rehabilitative treatment programme in the Eupatoriya sanatorium "Druzhba". Our objective in this work was to study effects of antioxidant therapy on parameters associated with intracellular glycogen in patients with gingivitis in the presence of a concomitant illness. The data obtained permitted coming to the conclusion that development of gingivitis is of a manifest energy-intensive character, with a concurrent morbid medical condition being an aggravating factor. The use of antioxidant therapy in a combined treatment of the above category stomatological patients was found to shorten time they receive their treatment. Other positive effects of the above therapy include prevention of complications and activation of glycogen-producing function of homeostasis.

    Satherley, R; Howard, R; Higgs, S

    2015-01-01

    To systematically review evidence concerning disordered eating practices in dietary-controlled gastrointestinal conditions. Three key questions were examined: a) are disordered eating practices a feature of GI disorders?; b) what abnormal eating practices are present in those with GI disorders?; and c) what factors are associated with the presence of disordered eating in those with GI disorders? By exploring these questions, we aim to develop a conceptual model of disordered eating development in GI disease. Five key databases, Web of Science with Conference Proceedings (1900-2014) and MEDLINE (1950-2014), PubMed, PsycINFO (1967-2014) and Google Scholar, were searched for papers relating to disordered eating practices in those with GI disorders. All papers were quality assessed before being included in the review. Nine papers were included in the review. The majority of papers reported that the prevalence of disordered eating behaviours is greater in populations with GI disorders than in populations of healthy controls. Disordered eating patterns in dietary-controlled GI disorders may be associated with both anxiety and GI symptoms. Evidence concerning the correlates of disordered eating was limited. The presence of disordered eating behaviours is greater in populations with GI disorders than in populations of healthy controls, but the direction of the relationship is not clear. Implications for further research are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Arginase (ARG) is a metabolic enzyme present in two isoforms that hydrolyze l-arginine to urea and ornithine. In humans, ARG isoform 1 is also expressed in cells of the myeloid lineage. ARG activity promotes tumour growth and inhibits T lymphocyte activation. However, the two ARG transgenic mouse lines produced so far failed to show such effects. We have generated, in two different genetic backgrounds, transgenic mice constitutively expressing ARG1 under the control of the CD68 promoter in macrophages and monocytes. Both heterozygous and homozygous transgenic mice showed a relevant increase in mortality at early age, compared with wild-type siblings (67/267 and 48/181 versus 8/149, respectively, both P < 0.005). This increase was due to high incidence of haematologic malignancies, in particular myeloid leukaemia, myeloid dysplasia, lymphomas and disseminated intravascular coagulation (DIC), diseases that were absent in wild-type mice. Atrophy of lymphoid organs due to reduction in T-cell compartment was also detected. Our results indicate that ARG activity may participate in the pathogenesis of lymphoproliferative and myeloproliferative disorders, suggest the involvement of alterations of L-arginine metabolism in the onset of DIC and confirm a role for the enzyme in regulating T-cell homeostasis.

The diagnostic criteria are in the process of review, and the probable four new categories are: anorexia nervosa, bulimia nervosa, binge eating disorder, and eating disorder not otherwise specified. These categories will also be broader than they were previously, which will affect the population prevalence; the present lifetime prevalence of all eating disorders is about 5%. Eating disorders can be associated with profound and protracted physical and psychosocial morbidity. The causal factors underpinning eating disorders have been clarified by understanding about the central control of appetite. Cultural, social, and interpersonal elements can trigger onset, and changes in neural networks can sustain the illness. Overall, apart from studies reporting pharmacological treatments for binge eating disorder, advances in treatment for adults have been scarce, other than interest in new forms of treatment delivery.

    Full Text Available Genetic advances in the past three decades have transformed our understanding and treatment of many human diseases including neurogenetic disorders. Most neurogenetic disorders can be classified as “rare disease,” but collectively neurogenetic disorders are not rare and are commonly encountered in general pediatric practice. The authors decided to select eight relatively well-known neurogenetic disorders including Down syndrome, Angelman syndrome, Prader–Willi syndrome, Smith–Magenis syndrome, congenital central hypoventilation syndrome, achondroplasia, mucopolysaccharidoses, and Duchenne muscular dystrophy. Each disorder is presented in the following format: overview, clinical characteristics, developmental aspects, associated sleep disorders, management and research/future directions.

    2015-01-01

    Synopsis Elevated serum eosinophil levels have been associated with multiple disorders of immune deficiency or immune dysregulation. Although primary immunodeficiency diseases (PIDD) are rare, it is important to consider these in the differential diagnosis of patients with eosinophilia. This review discusses the clinical features, laboratory findings, diagnosis, and genetic basis of disease of several disorders of immune deficiency or dysregulation – all which have documented eosinophilia as part of the syndrome. The article includes autosomal dominant hyper IgE syndrome, DOCK8 deficiency, PGM3 deficiency, ADA-SCID, Omenn syndrome, Wiskott-Aldrich syndrome, Loeys-Dietz syndrome, autoimmune lymphoproliferative syndrome, immunodysregulation, polyendocrinopathy, enteropathy, X-linked syndrome, Comel-Netherton syndrome, and severe dermatitis, multiple allergies, and metabolic wasting syndrome (SAM).

    The idea of a moving present or `now' seems to form part of our most basic beliefs about reality. Such a present, however, is not reflected in any of our theories of the physical world. I show in this article that presentism, the doctrine that only what is present exists, is in conflict with modern relativistic cosmology and recent advances in neurosciences. I argue for a tenseless view of time, where what we call `the present' is just an emergent secondary quality arising from the interaction of perceiving self-conscious individuals with their environment. I maintain that there is no flow of time, but just an ordered system of events.

    Full Text Available Castleman%u2019s disease is a rare lymphoproliferative pathology which has two clinicoradiological forms; localized disease and disseminated disease. Histopathologically, Castleman%u2019s disease is evaluated in three groups; hyaline-vascular type, plasma cell type and mixed type. Patients are often asymptomatic and are diagnosed by radiological findings. The most common radiological presentation is huge lymph nodes in mediastinal area. Lymphadenopathy is most frequently observed in paratracheal lymph nodes. We wanted to emphasize this very rare entity and remind you this disease by the mean of a case with different radiological appearance.

    Full Text Available Few movement disorders seem to make a straightforward approach to diagnosis and treatment more difficult and frustrating than myoclonus, due to its plethora of causes and its variable classifications. Nevertheless, in recent years, exciting advances have been made in the elucidation of the pathophysiology and genetic basis of many disorders presenting with myoclonus. Here, we provide a review of all of the important types of myoclonus encountered in pediatric and adult neurology, with an emphasis on the recent developments that have led to a deeper understanding of this intriguing phenomenon. An up-to-date list of the genetic basis of all major myoclonic disorders is presented. Randomized studies are scarce in myoclonus therapy, but helpful pragmatic approaches at diagnosis as well as treatment have been recently suggested.

    Full Text Available During his time as a state senator in Illinois, Barack Obama voted “Present” 129 times, a deliberate act of nonvoting that subsequently became an important campaign issue during the 2008 presidential elections. In this article, I examine the use of Present votes in the Illinois state senate. I find evidence that Present votes can largely be characterized as protest votes used as a legislative tool by the minority party. Incorporating information from Present votes into a Bayesian polytomous item-response model, I find that this information increases the efficiency of ideal point estimates by approximately 35%. There is little evidence of significant moderation by Obama when Present votes are accounted for, though my results suggest that Obama’s voting record may have moderated significantly before his subsequent election to the U.S. Senate. My results also suggest that because legislative nonvoting may occur for a variety of reasons, naive inclusion of nonvoting behavior into vote choice models may lead to biased results.

    This retrospective study evaluates the impact of rituximab on PTLD response and survival in a single-centre cohort. PTLD cases between 1984 and 2009, including heart, kidney, liver and lung transplant recipients, were included. Survival was analysed taking into account the type of PTLD (monomorphic vs. polymorphic), EBV infection status, IPI score, Ann Arbor stage and use of rituximab. Among 1335 transplanted patients, 24 developed PTLD. Median age was 54 yr (range 29-69), median time to diagnosis 50 months (range 0-100). PTLD type was predominantly late/monomorphic (79% and 75%), mostly diffuse large B-cell type. Overall response rate (ORR) was 62% (66% rituximab vs. 50% non-rituximab; P = 0.5). R-CHOP-like regimens were used most frequently (72% of patients treated with rituximab). Median overall survival was 64 months (CI 95% 31-96). OS was significantly increased in patients treated with rituximab (P = 0.01; CI 95% rituximab 58-79 months; non-rituximab 1-30 months). Post-transplant immunosuppression regimen had no effect on survival or time to PTLD, except for cyclosporine A (CyA), which associated with increased time to PTLD (P = 0.02). Rituximab was associated with increased survival in our single-centre series, and it should be considered as first-line therapy for PTLD patients. The possible protective effect of CyA for development of PTLD should be prospectively evaluated.

    A patient with AML (FAB M4Eo) developed EBV-LPD 1.5 months after allogeneic BMT from his one locus-mismatched mother, the diagnosis being confirmed on day +82. Attempts to eradicate the monoclonally proliferating LPD using chemotherapy (VP16/dexamethasone) followed by two doses of EBV-specific CTL and one dose of unstimulated donor leukocytes were not successful. We assume delay of infusions (day +100, +107) and insufficient CTL cell doses (total 9.2 x 10(6)) may have been responsible for the poor outcome in this case.

  4. Antileukemic activity of sulforaphane in primary blasts from patients affected by myelo- and lympho-proliferative disorders and in hypoxic conditions.

    Full Text Available Sulforaphane is a dietary isothiocyanate found in cruciferous vegetables showing antileukemic activity. With the purpose of extending the potential clinical impact of sulforaphane in the oncological field, we investigated the antileukemic effect of sulforaphane on blasts from patients affected by different types of leukemia and, taking into account the intrinsically hypoxic nature of bone marrow, on a leukemia cell line (REH maintained in hypoxic conditions. In particular, we tested sulforaphane on patients with chronic lymphocytic leukemia, acute myeloid leukemia, T-cell acute lymphoblastic leukemia, B-cell acute lymphoblastic leukemia, and blastic NK cell leukemia. Sulforaphane caused a dose-dependent induction of apoptosis in blasts from patients diagnosed with acute lymphoblastic or myeloid leukemia. Moreover, it was able to cause apoptosis and to inhibit proliferation in hypoxic conditions on REH cells. As to its cytotoxic mechanism, we found that sulforaphane creates an oxidative cellular environment that induces DNA damage and Bax and p53 gene activation, which in turn helps trigger apoptosis. On the whole, our results raise hopes that sulforaphane might set the stage for a novel therapeutic principle complementing our growing armature against malignancies and advocate the exploration of sulforaphane in a broader population of leukemic patients.

    SUMMARY We described 1 case of autoimmune lymphoproliferative syndrome ( ALPS) , first diagnosed in our hospital, and reviewed the recent literature. The 11-month old male patient presented with a histo-ry of splenomegaly and hepatomegaly since 1 month after birth. He suffered recurrent infectious diseases including cytomegalovirus infection, parvovirus B19 infection and chronic diarrhea disease. Besides, his symptoms included hemolytic anemia and thrombocytopenia. The laboratory abnormality indicated an ex-panded population of alpha/beta double-negative T cells (DNTs) (27. 18% of lymphocytes, 35. 16% of CD3 + T lymphocytes) in peripheral blood, and autoantibodies including antinuclear antibody, double-stranded DNA and rheumatic factor were positive. Hyper gamma globulinemia and positive direct Coombs tests were seen in the patient. His parents were both healthy and denied autoimmune diseases. We iden-tified a heterozygous point mutation in exon 3 of the FAS gene carrying c. 309 A>C, resulting in a single base pair substitution in exon 3 of FAS gene which changed the codon of Arg103 to Ser103 . Unfortunate-ly, we were unable to obtain the gene results of the child' s parents. The patient was treated with glu-cocorticoids in our hospital and with mycophenolatemofetil in other hospital. And we were informed that his anemia condition relieved through the telephone follow-up, but he still suffered recurrent infections, hepatomegaly and splenomegaly still existed. As we all know ALPS is characterized by defective lympho-cyte apoptosis, and thus cause lymphoproliferative disease and autoimmune disease, and increase the risk of lymphoma. It is more likely to be misdiagnosed as other diseases. ALPS should be suspected in the case of chronic lymphadenopathy, splenomegaly and autoimmune features. Flow cytometry approach is helpful for the diagnosis. Immunosuppressive drugs are the necessary treatment.%报道2013年10月北京大学第一医院诊治的1例自身免疫

    Asperger disorder was first described in 1944 by the Austrian pediatrician, Hans Asperger. It was introduced as a separate diagnostic category from autistic disorder in DSM-IV and ICD-10. The pattern of comorbidity in Asperger disorder is different from autistic disorder, with a higher level of psychosis, violent behavior, anxiety, and mood disorders. We present three cases of Asperger disorder diagnosed for the first time in adulthood, with psychosis being the predominant reason for the referral. In each case, the psychosis improved with antipsychotic treatment, although core autistic symptoms remained the same.

    Full Text Available Bipolar disorder is characterized by recurrent attacks, significantly disrupts the functionality of a chronic mental disorder. Although there is growing number of studies on the neurobiological basis of the disorder, the pathophysiology has not yet been clearly understood. Structural and functional imaging techniques present a better understanding of the etiology of bipolar disorder and has contributed significantly to the development of the diagnostic approach. Recent developments in brain imaging modalities have let us learn more about the underlying abnormalities in neural systems of bipolar patients. Identification of objective biomarkers would help to determine the pathophysiology of bipolar disorder, a disorder which causes significant deterioration in neurocognitive and emotional areas.

    Movement disorders are common in psychiatry. The movement disorder can either be the symptom of a psychiatric disorder, can share a common aetiological factor with it, or can be the consequence of psychopharmacological therapy. Most common features include tic, stereotypy, compulsion, akathisia, dyskinesias, tremor, hypokinesia and disturbances of posture and gait. We discuss characteristics and clinical importance of these features. Movement disorders are frequently present in mood disorders, anxiety disorders, schizophrenia, catatonia, Tourette-disorder and psychogenic movement disorder, leading to differential-diagnostic and therapeutical difficulties in everyday practice. Movement disorders due to psychopharmacotherapy can be classified as early-onset, late-onset and tardive. Frequent psychiatric comorbidity is found in primary movement disorders, such as Parkinson's disease, Wilson's disease, Huntington's disease, diffuse Lewy-body disorder. Complex neuropsychiatric approach is effective concerning overlapping clinical features and spectrums of disorders in terms of movement disorders and psychiatric diseases.
