    Post-transplant lymphoproliferative disorders (PTLD) are a serious complication after solid organ or allogeneic hematopoietic stem cell transplantation and include a range of diseases from benign proliferations to malignant lymphomas. Risk factors for developing PTLD include Epstein-Barr virus (EBV) infection, recipient age, transplanted organ, type of immunosuppression, and genetics. Uncontrolled proliferation of EBV-infected B cells is implicated in EBV-positive PTLD, whereas the pathogenesis of EBV-negative PTLD may be similar to non-Hodgkin's lymphoma in the general population. The World Health Organization (WHO) classifies PTLD into four categories: early lesions, polymorphic PTLD, monomorphic PTLD, and classical Hodgkin's lymphoma (cHL). Treatment is aimed at cure of PTLD, while maintaining transplanted organ function. However, there are no established guidelines for the treatment of PTLD. Immune suppression reduction (ISR) is the first line of treatment in most cases, with more recent data suggesting early use of rituximab. In more aggressive forms of PTLD, upfront chemotherapy may offer a better and more durable response. Sequential therapy using rituximab followed by chemotherapy has demonstrated promising results and may establish a standard of care. Novel therapies including anti-viral agents, adoptive immunotherapy, and monoclonal antibodies targeting cytokines require further study in the prevention and treatment of PTLD.

    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.)

    Infectious mononucleosis is the syndrome produced by primary infection with Epstein-Barr virus during adolescence or early adulthood. In immunosuppressed individuals, depressed T-cell function allows the Epstein-Barr virus-driven B-cell proliferation to continue unabated, potentially leading to a lymphoproliferative disorder. A 15-year-old girl with a history of ulcerative colitis treated with 6-mercaptopurine and mesalamine presented with the acute onset of a rapidly enlarging, ulcerative nodule on her left lower eyelid 4 weeks following recovery from infectious mononucleosis. The biopsy revealed an Epstein-Barr virus-positive lymphoproliferative disorder. Systemic disease was absent. Following discontinuation of 6-mercaptopurine, the patient was treated with two courses of intravenous cyclophosphamide. The lesion resolved completely and she remains disease free at 14 months following diagnosis. We report a solitary cutaneous lesion of an immunosuppression-related lymphoproliferative disorder (IR-LPD) occurring as a complication of infectious mononucleosis, and review the pathogenesis and reported cases of Epstein-Barr virus-related immunosuppression-related lymphoproliferative disorder arising in the setting of inflammatory bowel disease. It is important for dermatologists and dermatopathologists to be aware of the occurrence of IR-LPD in patients being treated for inflammatory conditions, including inflammatory bowel disease. Given the role of primary infection with Epstein-Barr virus in the development of IR-LPD, consideration may be given to assessing Epstein-Barr virus status prior to initiating immunosuppressive therapy in young patients. © 2010 Wiley Periodicals, Inc.

    CD30 primary cutaneous lymphoproliferative diseases include both lymphomatoid papulosis (LyP) and primary cutaneous anaplastic large cell lymphoma (PCALCL). The neoplastic cell of most primary CD30 lymphoproliferative disorders is CD4 positive. The terminology LyP "type D" has been used to describe a growing number of cases of LyP with a predominantly CD8 infiltrate. PCALCL with a CD8 phenotype has also been described, which presents a particularly difficult diagnostic and management challenge, given the difficulty in distinguishing it histologically from other cytotoxic lymphomas such as primary cutaneous aggressive epidermotropic CD8 cytotoxic T-cell lymphoma and CD8 gamma/delta and natural killer/T-cell lymphoma. We report 7 additional cases of these rare cutaneous CD8/CD30 lymphoproliferative disorders. We also present a unique case of CD8/CD30 LyP with histologic similarities to LyP type B. In all 7 of our cases of CD8 LyP and CD8 anaplastic large cell lymphoma, we found focal to diffuse MUM-1 positivity. We propose that MUM-1 may represent an adjunctive marker for CD8 lymphoproliferative disease. Finally, we review the current literature on cases of CD8 LyP and PCALCL. For the 106 cases examined, we found similar clinical and histologic features to those reported for traditional CD4CD30 LyP and PCALCL.

    Granulomatous cutaneous T-cell lymphomas (CTCL) and lymphomatoid granulomatosis are considered granulomatous lymphoproliferative disorders. The most common types of granulomatous CTCL are granulomatous mycosis fungoides and granulomatous slack skin. Lymphomatoid granulomatosis is a rare Epstein-Barr virus driven lymphoproliferative disorder. This article reviews the etiopathogenesis, clinical presentation, systemic associations, and management of both granulomatous slack skin syndrome and lymphomatoid granulomatosis.

    Objective: To study the radiographic findings of lymphoproliferative disorders of the lung. Methods: Twenty-five patients with lymphoproliferative disorders of the lung were examined by X-ray film, tomography, and CT. Results: Multiple and mediastinal lymphadenopathy were observed in 2 patients with pulmonary pseudolymphoma. Multiple nodules or masses were observed in 4 patients with pulmonary lymphomatoid granulomatosis. Hilar and mediastinal lymphadenopathy was observed in each patient with angioimmunoblastic lymphadenopathy, 2 patients had multiple nodules or masses, 8 patients had single or multiple patchy infiltrations, 10 had diffuse interstitial infiltrations. 3 patients with Castlemen' disease had a mass in the mediastinum, and another patient had mediastinal lymphadenopathy. Conclusion: Radiographic findings of lymphoproliferative disorders of the lung are varied, and the final diagnosis relies on pathology

    Pulmonary lymphoproliferative disorders include plasma cell granuloma, Castleman's disease, pseudolymphoma, lymphocytic interstitial pneumonia, angioimmunoblastic lymphadenopathy and lymphomatoid granulomatosis. We carried out a retrospective study for the purpose of analysing the clinical and radiological findings of 16 cases of pulmonary lymphoproliferative disorders seen during the decade 1980-1990. The cases comprised 8 lymphocytic interstitial pneumonia, 5 lymphomatoid granulomatosis, 2 plasma cell granuloma and 1 angioimmunoblastic lymphadenopathy. Owing to the overlap and low specificity of the radiological patterns in these processes, histopathological examination is required. In view of the frequent evolution of pulmonary lymphoproliferative disorders to malignant lymphoma (4 cases, 1 of lymphocytic interstitial pneumonia and 3 of lymphomatoid granulomatosis, in our series) we provide a description of the radiological changes that occur during this process.

    Full Text Available Epstein-Barr virus (EBV-associated post-transplant lymphoproliferative disorder (PTLD is a serious complication of organ transplantation. The gastrointestinal (GI tract is a common site involved, but non-specific signs and symptoms often delay the diagnosis. We report a case of EBV-associated GI-PTLD in a 68-year-old kidney transplant patient who received the kidney ten months earlier. He presented with chronic diarrhea and developed massive pneumo-peritoneum secondary to multiple colonic perforations.

    Posttransplant lymphoproliferative disorders (PTLD), developing after immunosuppressive therapy in human organ-graft recipients, are, for the most part, Epstein-Barr virus-induced. The earlier the diagnosis is made, the greater the potential for reversibility. The chest radiographs and CT scans of 10 patients with thoracic locations of PTLD were reviewed. Mediastinal and hilar adenopathy, pulmonary nodules, and pleural thickening or effusion were encountered. The incidence of partial resolution with clinical remission appears to be noteworthy, and in all likelihood is related to the extensive necrosis that is frequently seen. Slow regression, transitory deterioration in one case, and localization only on the graft side in two cases, were observed. These morphological and evolutionary peculiarities must be known in order to optimize the diagnosis, and thus the prognosis, of these very original disorders. (orig.)

  15. Relative adrenal insufficiency in post-transplant lymphoproliferative disorder.

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available Post-transplant lymphoproliferative disorder is treated with rapid decrement of immunosuppressive therapy. This cannot be achieved with ease in patients on long-term glucocorticoid therapy, as chronically suppressed adrenal glands may not be capable of mounting adequate response to stress. A 52-year-old Caucasian male presented with fever, orthostatic hypotension, lymphadenopathy and hyponatraemia. Serum cortisol levels were within normal levels with a sub optimal response to stimulation by ACTH. Hyponatraemia and orthostasis responded poorly to fluid restriction, saline and salt repletion but corrected after increasing the steroid dose. The normal baseline cortisol levels represented a stimulated adrenal gland, however, the ACTH stimulation had inadequate response. This sub optimal stimulation and a good response to increased steroids suggest the presence of relative or occult adrenal insufficiency. Relative adrenal insufficiency must be considered in patients who have received prolonged glucocorticoid therapy and have symptoms such as hypotension and/or hyponatraemia.

    Lymphomatoid papulosis (LyP) is classified as a CD30+ primary cutaneous lymphoproliferative disease. The phenotypic variability along the spectrum of CD30+ lymphoproliferative diseases is highlighted by the distinct histologic subtypes of LyP types A, B, C, and the more recently described types D, E, and F. We report the case of an elderly woman with a clinical presentation and histopathologic findings consistent with LyP, whose atypical CD30+ infiltrate uniquely demonstrated a spindle-cell morphology. To our knowledge, this is the first reported case of LyP characterized by CD30+ spindle-shaped cells, and may represent a new and distinct histologic variant of LyP. © 2016 John Wiley & Sons A/S.

    Inflammatory bowel disease (IBD) patients on thiopurine therapy are at increased risk of Epstein-Barr virus (EBV)-associated lymphomas. This virus is frequently detected in the intestinal mucosa of IBD patients and may cause a wide spectrum of lymphoproliferations similar to post-transplantation lymphoproliferative disorders (PTLDs). We aimed to assess whether histological aberrations aid in predicting EBV presence and to correlate histological assessment and EBV load with disease outcome in IBD. We included all IBD patients from our centre who underwent EBV testing of intestinal biopsies between January 2004 and October 2013. All biopsies were classified according to the WHO PTLD classification and the EBV load was scored per high-power field (HPF). Clinical data were collected from patient charts. Reported clinical outcomes included colectomy, need for chemotherapy and mortality. Our cohort included 58 patients: 28 were EBV-positive and 30 EBV-negative. An atypical infiltrate was seen more frequently in EBV-positive than in EBV-negative patients (57.1 versus 3.3%; p < 0.001). A high EBV load occurred more frequently in EBV-positive patients undergoing colectomy than in EBV-positive patients without colectomy (50.0 versus 10.0%; p = 0.048). Monomorphic lymphoproliferative disorders, including two overt lymphomas, were present in 10 patients. Reduction of immunosuppression resulted in histological normalization and loss of EBV expression in seven of eight non-lymphoma patients. The presence of atypical infiltrate in the intestinal mucosa of IBD patients warrants EBV testing. Reduction of immunosuppression is an effective strategy to achieve morphological normalization and loss of EBV. Lymphoproliferation related to IBD appears to have less aggressive clinical behaviour than PTLDs. Copyright © 2015 European Crohn’s and Colitis Organisation (ECCO).

    Post-transplantation lymphoproliferative disorders are serious complications of organ transplantation which treatment is not yet standardized. To describe the clinical response, overall and graft survival of patients in our center with this complication after kidney transplantation, which received rituximab as part of their treatment as well as conversion to m-TOR. Retrospective study, which included patients, diagnosed with post-transplant lymphoproliferative disorders after kidney transplantation from January 2011 to July 2014. Eight cases were found with a wide spectrum of clinical presentations. Most had monomorphic histology, 85% were associated with Epstein-Barr virus, 25% of patients had tumor involvement of the renal graft, and 12.5% ​​had primary central nervous system lymphoma. All patients were managed with reduction of immunosuppression, conversion to m-TOR (except one who lost the graft at diagnosis) and rituximab-based therapy. The overall response rate was 87.5% (62.5% complete response, 25% partial response). Survival was 87.5% with a median follow-up of 34 months. An additional patient lost the graft, with chronic nephropathy already known. All the remaining patients had stable renal function. There are no standardized treatment regimens for lymphoproliferative disorders after kidney transplantation, but these patients can be managed successfully with reduction of immunosuppression, conversion to m-TOR and rituximab-based schemes.

    Epstein-Barr virus (EBV) was discovered 50 years ago from an african Burkitt lymphoma cell line. EBV-associated lymphoproliferative disorders (LPDs) are life- threatening diseases, especially in children. In this article, we review EBV-associated LPDs, especially in the area of primary immunodeficiency disease (PID). We searched PubMed for publications with key words including EBV infection, lymphoma, LPDs and PID, and selected the manuscripts written in English that we judged to be relevant to the topic of this review.On the basis of the data in the literature, we grouped the EBV-associated LPDs into four categories: nonmalignant disease, malignant disease, acquired immunodeficiency disease and PID. Each category has its own risk factor for LPD development. EBV-associated LPD is a complex disease, creating new challenges for diagnosis and treatment.

    A joint working group established by the Haemato-oncology subgroup of the British Committee for Standards in Haematology (BCSH) and the British Transplantation Society (BTS) has reviewed the available literature and made recommendations for the diagnosis and management of post-transplant lymphoproliferative disorder (PTLD) in adult recipients of solid organ transplants. This review details the risk factors predisposing to development, initial features and diagnosis. It is important that the risk of developing PTLD is considered when using post transplant immunosuppression and that the appropriate investigations are carried out when there are suspicions of the diagnosis. These must include tissue for histology and computed tomography scan to assess the extent of disease. These recommendations have been made primarily for adult patients, there have been some comments made with regard to paediatric practice.

    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.

    2015-01-01

    Epstein-Barr Virus (EBV), the first human virus related to oncogenesis, was initially identified in a Burkitt lymphoma cell line in 1964. EBV infects over 90% of the world’s population. Most infected people maintain an asymptomatic but persistent EBV infection lifelong. However, in some individuals, EBV infection has been involved in the development of cancer and autoimmune disease. Nowadays, oncogenic potential of EBV has been intensively studied in a wide range of human neoplasms, including Hodgkin’s lymphoma (HL), non-Hodgkin’s lymphoma (NHL), nasopharyngeal carcinoma (NPC), gastric carcinoma (GC), etc. EBV encodes a series of viral protein and miRNAs, promoting its persistent infection and the transformation of EBV-infected cells. Although the exact role of EBV in the oncogenesis remains to be clarified, novel diagnostic and targeted therapeutic approaches are encouraging for the management of EBV-related malignancies. This review mainly focuses on the experimental and clinical advances of EBV-associated lymphoproliferative disorders. PMID:26628948

    Introduction Monomorphic post-transplant lymphoproliferative disorders (PTLD) are the most aggressive type of PTLD occurring after solid organ transplantation (SOT). Current guidelines for treatment suggest a stepwise approach that includes a reduction of immunosuppression (RIS) with or without rituximab, followed by chemotherapy if there is no response. Nevertheless, recommendations regarding the extent and duration of RIS are non-standardized and RIS as an initial strategy may be associated with an unacceptably high frequency of graft loss and disease progression. Patients and Methods We reviewed the outcome of a combination program of aggressive chemo-immunotherapy and complete withdrawal of immunosuppression in treating 22 patients with monomorphic PTLD between January 1995 and August 2012. Results 12 of 22 patients (55%) received CHOP-R every 2 weeks (dose dense CHOP-R) and 10 patients received other doxorubicin-based regimens. There was no treatment related mortality (TRM). Complete response (CR) was seen in 91% of patients. Median overall survival was 9.61 years with 95% CI (5.21-10.74). Median progression free survival (PFS) was 5.39 years with 95% CI (2.10-10.74). The graft-rejection rate was 18% with 95% CI (0.03-0.34). Conclusion We conclude that the use of aggressive chemo-immunotherapy in combination with withdrawal of immunosuppression approach yields excellent results and should be prospectively studied in a multi-institutional setting.

    Posttransplant lymphoproliferative disorder (PTLD) can be resolved in many transplant patients by the reduction or cessation of immunosuppression, after which many grafts continue to function as the result of a form of operational tolerance. When graft function deteriorates, retransplantation may...... be an option. Cytokines such as interleukin (IL)-10 and IL-18 may play a role in PTLD tolerance induction and tumor regression. We report long-term follow-up on the duration of graft tolerance and the course of retransplantation in a series of patients who underwent kidney transplantation and demonstrated PTLD...

    Employing radionuclide scanning, the volume of the spleen, its red cell pool and plasma pool have been measured in vivo, and the relative proportions of cellularity and vascularity of the spleen have been calcualted in 51 patients with myeloproliferactive and lymphoproliferative disorders. In primary proliferative polycythaemia (polycythaemia vera), the increase of spleen size was attributed mainly to the increase of splenic vascularity; in myelofibrosis and in hairy cell leukaemia, the increase of spleen size was associated with increase in both splenic vascularity and cellularity, whilst in size was associated with increase in both splenic vascularity and cellularity, whilst in CGL and CLL the increase was attributed more to cellularity than to vascularity.

    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 Hairy B-cell lymphoproliferative disorder (HBLD is one of chronic polyclonal B-cell lymphocytosis. We report a 47-year-old female Japanese patient diagnosed as having HBLD based on lymphocytosis with hairy cell appearance and characteristic phenotypes including CD11c+, and without B-cell monoclonalities. She was a non-smoker, and possessed HLA-DR4. She has been closely followed up without treatment and lymphoma development for over five years. Although this disease is quite rare and has been reported, to our knowledge, in only 13 Japanese cases, an accurate diagnosis, particularly differential diagnosis from persistent polyclonal B-cell lymphocytosis or hairy cell leukemia-Japanese variant is essential for the prevention of unnecessary treatments.

    2009-01-01

    Full Text Available The Epstein-Barr virus (EBV associated Post-Transplant Lymphoproliferative Disorders (PTLD are increasingly recognized as a fatal complication of hematological stem cell transplantation (HSCT. Thoracic involvement, that may be isolated or part of a disseminated disease, usually encompasses pulmonary nodules or masses and mediastinal lymph node enlargement. The current case study presents 2 patients who underwent HSCT, one allogenic and the other autologous, who developed an exceptional endobronchial EBV related PTLD. The first patient had a fleshy white endobronchial mass resulting in a right upper lobe atelectasis and the second had an extensive necrotising mucosa from trachea to both basal bronchi without any significant change of lung parenchyma on the CT scan. In both cases, the diagnosis was made by bronchial biopsies. Physicians should be aware of an endobronchial pattern of EBV associated PTLD after HSCT to permit quick diagnosis and therapeutic intervention.

    Full Text Available Posttransplant lymphoproliferative disorder (PTLD is a spectrum of diseases that involves abnormal lymphoid and/or plasmacytic proliferation in patients with solid organ or hematopoietic cell transplantation. It is a condition with a low incidence of 3.5–4.3% in liver transplant (LT recipients. This case involves a 63-year-old male with history of LT for chronic HCV induced cirrhosis who presented with abdominal distension related to worsening ascites. Cytological ascitic fluid analysis revealed EBV (+ malignant cells without a malignant focal point on imaging. Diagnosis of monomorphic PTLD with primary effusion lymphoma-like morphology and immunophenotype was established. This case highlights the complexity in diagnosis, different diagnostic modalities, and rare clinical presentations of PTLD.

    Most medically-related radiation is caused by diagnostic examinations, in particular by computed tomography (CT). The purpose of this research is to reduce radiation doses faced by the population frequently exposed to such procedures-those with lymphoproliferative disorders. The research was conducted comparing radiation-exposition doses received by the radiosensitive organs (thyroid, lens, breast and gonad) using the standard thoracic CT protocol with the radiation received using the low-dose protocol, while maintaining display quality. The standard-dose thoracic protocol implies 120 kV and 150 mAs. The low-dose protocol was conducted on the same device using 120 kV and 30 mAs. We confirmed the hypothesis that the use of the low-dose thoracic CT protocol leads to a reduction in radiation dose without compromising display quality. It is further expected that a reduction in doses will reduce the risk of radiation-related mutations. (author)

    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. Nichtdestotrotz unterscheiden sich die Behandlungsmoeglichkeiten signifikant und vor allem lokalisierte Stadien koennen kurativ entweder mit Strahlentherapie (RT) und/oder Operation behandelt werden. 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. Das rezidivfreie Ueberleben betrug zum Zeitpunkt der letzten Nachsorgeuntersuchung 52 Monate mit einer Gesamtueberlebenszeit von 62 Monaten seit der Diagnose. Die konventionelle fraktionierte moderat dosierte RT scheint eine gut

    Full Text Available Posttransplant lymphoproliferative disorder (PTLD is a potentially fatal disease that arises in 2%–10% of solid organ and hematopoietic stem cell transplants and is most frequently of B-cell origin. This very heterogeneous disorder ranges from benign lymphoproliferations to malignant lymphomas, and despite the clear association with Epstein-Barr Virus (EBV infection, its etiology is still obscure. Although a number of risk factors have been identified (EBV serostatus, graft type, and immunosuppressive regimen, it is currently not possible to predict which transplant patient will eventually develop PTLD. Genetic studies have linked translocations (involving C-MYC, IGH, BCL-2, various copy number variations, DNA mutations (PIM1, PAX5, C-MYC, RhoH/TTF, and polymorphisms in both the host (IFN-gamma, IL-10, TGF-beta, HLA and the EBV genome to B-cell PTLD development. Furthermore, the tumor microenvironment seems to play an important role in the course of disease representing a local niche that can allow antitumor immune responses even in an immunocompromised host. Taken together, B-cell PTLD pathogenesis is very complex due to the interplay of many different (patient-dependent factors and requires thorough molecular analysis for the development of novel tailored therapies. This review aims at giving a global overview of the currently known parameters that contribute to the development of B-cell PTLD.

    Some chemotherapeutic agents can cause iatrogenic lymphoproliferative disorders. In analogy to what has been observed with other nucleoside analogues such as cladribine and fludarabine, we document the first case of an Epstein-Barr virus-positive, iatrogenic immunodeficiency-associated, lymphoproliferative disease, formally resembling polymorphic post-transplant lymphoproliferative disease in a patient treated with azacitidine (Vidaza) for chronic myelomonocytic leukaemia (CMML). A 78-year-old female patient was diagnosed with CMML in January 2012, and treatment with azacitidine was initiated, which lasted for five cycles from February until June 2012. The patient was hospitalized in June 2012 under the suspicion of pneumonia. Transformation of the CMML was suspected at that time too. During hospitalization, a generalized enlargement of the lymph nodes and the spleen was noticed. The patient rapidly deteriorated and finally died of respiratory insufficiency. At autopsy, an Epstein-Barr virus-associated lymphoproliferative disorder, resembling polymorphic post-transplant lymphoproliferative disease with involvement of the lymph nodes, the spleen and the lung and causing necrotizing pneumonia, was diagnosed. Diagnostic criteria for diffuse large B-cell lymphoma or infectious mononucleosis-like lymphoproliferative disease were not met. This is the first documented case of an azacitidine-associated lymphoproliferative disease, raising awareness for possible not yet known side effects of this drug, which should be kept in mind by oncologists and pathologists.

    Posttransplant lymphoproliferative disorder (PTLD) is a well-recognized complication of solid organ transplantation and commonly affects upper airway lymphoid tissue. Tracheal and laryngeal involvement in patients with PTLD, however, is rare. We present one such case. We report the case of a patient with recurrent PTLD involving the larynx and trachea and describe the presentation, evaluation, management, and outcome. An 11-year-old boy who underwent bilateral nephrectomy and renal transplantation as an infant was admitted to the hospital with chronic cough, fever, stridor, and dyspnea. His post-transplantation course was complicated by PTLD in cervical lymph nodes at 9 years of age that was successfully treated with chemotherapy. A computed tomographic scan during his present admission revealed supraglottic swelling, a distal tracheal mass, and paratracheal lymph node enlargement. The patient underwent laryngoscopy and bronchoscopy with biopsy specimens taken from the right laryngeal ventricle and distal trachea. Pathologic examination yielded a diagnosis of Epstein-Barr virus-positive PTLD. The patient was treated with chemotherapy, which resulted in resolution of the airway lesions, as seen on repeat bronchoscopy. This is the first report, to our knowledge, of recurrent PTLD involving simultaneous lesions in the larynx and the trachea. PTLD in the head and neck can present as lymphoid hypertrophy, airway obstruction, stridor, or cough. A high degree of clinical suspicion is essential for prompt diagnosis of this life-threatening complication.

    We report the first two cases of posttransplant lymphoproliferative disorder (PTLD) in recipients of islet transplants worldwide. First, a 44-year-old recipient of three islet infusions developed PTLD 80 months after his initial transplantation, presenting with abdominal pain and diffuse terminal ileum thickening on imaging. He was treated with surgical excision, reduction of immunosuppression, and rituximab. Seven months later, he developed central nervous system PTLD, presenting with vertigo and diplopia; immunosuppression was discontinued, resulting in graft loss, and he was given high-dose methotrexate and underwent consolidative autologous stem cell transplantation. He remains in remission 37 months after the initial diagnosis. Second, a 58-year-old female recipient of two islet infusions developed PTLD 24 months after initial islet infusion, presenting with pancytopenia secondary to extensive bone marrow involvement. Immunosuppression was discontinued, resulting in graft loss, and she received rituximab and chemotherapy, achieving complete remission. Both patients were monomorphic B cell PTLD subtype by histology and negative for Epstein-Barr virus in tissue or blood. These cases document the first occurrences of this rare complication in islet transplantation, likely secondary to prolonged, intensive immunosuppression, and highlight the varying clinical manifestations of PTLD. Further studies are needed to determine incidence rate and risk factors in islet transplantation. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

    This article highlights recent discoveries about Notch activation and its oncogenic functions in lymphoid malignancies, and discusses the therapeutic potential of Notch inhibition. NOTCH mutations arise in a broad spectrum of lymphoid malignancies and are increasingly scrutinized as putative therapeutic targets. In T-cell acute lymphoblastic leukemia (T-ALL), NOTCH1 mutations affect the extracellular negative regulatory region and lead to constitutive Notch activation, although mutated receptors remain sensitive to Notch ligands. Other NOTCH1 mutations in T-ALL and NOTCH1/2 mutations in multiple B-cell malignancies truncate the C-terminal proline (P), glutamic acid (E), serine (S), threonine (T)-rich (PEST) domain, leading to decreased Notch degradation after ligand-mediated activation. Thus, targeting Notch ligand-receptor interactions could provide therapeutic benefits. In addition, we discuss recent reports on clinical testing of Notch inhibitors in T-ALL that influenced contemporary thinking on the challenges of targeting Notch in cancer. We review advances in the laboratory to address these challenges in regards to drug targets, the Notch-driven metabolome, and the sophisticated protein-protein interactions at Notch-dependent superenhancers that underlie oncogenic Notch functions. Notch signaling is a recurrent oncogenic pathway in multiple T- and B-cell lymphoproliferative disorders. Understanding the complexity and consequences of Notch activation is critical to define optimal therapeutic strategies targeting the Notch pathway.

    Post-transplant lymphoproliferative disorder (PTLD) is a common complication of therapeutic immunosuppression after organ transplantation. Gene expression profile facilitates the identification of biological difference between Epstein-Barr virus (EBV) positive and negative PTLDs. Previous studies mainly implemented variance/regression analysis without considering unaccounted array specific factors. The aim of this study is to investigate the gene expression difference between EBV positive and negative PTLDs through partial least squares (PLS) based analysis. With a microarray data set from the Gene Expression Omnibus database, we performed PLS based analysis. We acquired 1188 differentially expressed genes. Pathway and Gene Ontology enrichment analysis identified significantly over-representation of dysregulated genes in immune response and cancer related biological processes. Network analysis identified three hub genes with degrees higher than 15, including CREBBP, ATXN1, and PML. Proteins encoded by CREBBP and PML have been reported to be interact with EBV before. Our findings shed light on expression distinction of EBV positive and negative PTLDs with the hope to offer theoretical support for future therapeutic study.

    High levels of circulating EBV load are used as a marker of post-transplant lymphoproliferative disorders (PTLD). There is no consensus regarding the threshold level indicative of an increase in peripheral EBV DNA. The aim of the study was to clinically validate a developed EBV quantification assay for early PTLD detection. Transversal study: paired peripheral blood mononuclear cells (PBMC), plasma and oropharyngeal lymphoid tissue (OLT) from children undergoing a solid organ transplant with (n=58) and without (n=47) PTLD. Retrospective follow-up: 71 paired PBMC and plasma from recipients with (n=6) and without (n=6) PTLD history. EBV load was determined by real-time PCR. The diagnostic ability to detect all PTLD (categories 1-4), advanced PTLD (categories 2-4) or neoplastic PTLD (categories 3 and 4) was estimated by analyzing the test performance at different cut-off values or with a load variation greater than 0.5log units. The higher diagnostic performance for identifying all, advanced or neoplastic PTLD, was achieved with cut-off values of 1.08; 1.60 and 2.47log EBVgEq/10(5) PBMC or 2.30; 2.60; 4.47loggEq/10(5) OLT cells, respectively. EBV DNA detection in plasma showed high specificity but low (all categories) or high (advanced/neoplastic categories) sensitivity for PTLD identification. Diagnostic performance was greater when: (1) a load variation in PBMC or plasma was identified; (2) combining the measure of EBV load in PBMC and plasma. The best diagnostic ability to identify early PTLD stages was achieved by monitoring EBV load in PBMC and plasma simultaneously; an algorithm was proposed.

    In up to 5-15% of studies of lymphoproliferative disorders (LPD) flow cytometry (FCM) or immunomorphologic methods cannot discriminate malignant from reactive processes. The aim of this work was to determine the usefulness of PCR for solving these diagnostic uncertainties. We analyzed IGH and TCRγ genes by PCR in 106 samples with inconclusive FCM results. A clonal result was registered in 36/106 studies, with a LPD being confirmed in 27 (75%) of these cases. Specifically, 9/9 IGH clonal and 16/25 TCRγ clonal results were finally diagnosed with LPD. Additionally, 2 clonal TCRγ samples with suspicion of undefined LPD were finally diagnosed with T LPD. Although polyclonal results were obtained in 47 of the cases studied (38 IGH and 9 TCRγ), hematologic neoplasms were diagnosed in 4/38 IGH polyclonal and in 1/9 TCRγ polyclonal studies. There were also 14 PCR polyclonal results (4 IGH, 10 TCRγ), albeit non-conclusive. Of these, 2/4 were eventually diagnosed with B-cell lymphoma and 3/10 with T-cell LPD. In 8 IGH samples the results of PCR techniques were non-informative but in 3/8 cases a B lymphoma was finally confirmed. We concluded that PCR is a useful technique to identify LPD when FCM is inconclusive. A PCR clonal B result is indicative of malignancy but IGH polyclonal and non-conclusive results do not exclude lymphoid neoplasms. Interpretation of T-cell clonality should be based on all the available clinical and analytical data. © 2013 Clinical Cytometry Society. Copyright © 2013 Clinical Cytometry Society.

    The setting of chronic immunosuppression in inflammatory bowel disease (IBD) may promote the proliferation of Epstein-Barr virus-positive neoplastic clones. We report two rare cases of Epstein-Barr virus-associated lymphoproliferative disorder in IBD patients: one resembled lymphomatoid granulomatosis, and the other was a lymphoma resembling Hodgkin lymphoma. There are currently no guidelines for the prevention of lymphoproliferative disorder in IBD patients on immunosuppressive therapy. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

  17. Notch-deficient skin induces a lethal systemic B-lymphoproliferative disorder by secreting TSLP, a sentinel for epidermal integrity.

    Full Text Available Epidermal keratinocytes form a highly organized stratified epithelium and sustain a competent barrier function together with dermal and hematopoietic cells. The Notch signaling pathway is a critical regulator of epidermal integrity. Here, we show that keratinocyte-specific deletion of total Notch signaling triggered a severe systemic B-lymphoproliferative disorder, causing death. RBP-j is the DNA binding partner of Notch, but both RBP-j-dependent and independent Notch signaling were necessary for proper epidermal differentiation and lipid deposition. Loss of both pathways caused a persistent defect in skin differentiation/barrier formation. In response, high levels of thymic stromal lymphopoietin (TSLP were released into systemic circulation by Notch-deficient keratinocytes that failed to differentiate, starting in utero. Exposure to high TSLP levels during neonatal hematopoiesis resulted in drastic expansion of peripheral pre- and immature B-lymphocytes, causing B-lymphoproliferative disorder associated with major organ infiltration and subsequent death, a previously unappreciated systemic effect of TSLP. These observations demonstrate that local skin perturbations can drive a lethal systemic disease and have important implications for a wide range of humoral and autoimmune diseases with skin manifestations.

    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.

    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.

    Diagnosis of lymphoproliferative disorders is one of the most challenging tasks faced by the cytologist. The initial cytomorphologic evaluation of lymphoproliferative lesions directs the choice of ancillary studies that ultimately lead to a diagnosis based on the World Health Organization classification system using a composite of clinical, morphologic, immunophenotypic, and molecular features. To evaluate the ability of participating laboratories in the College of American Pathologists Interlaboratory Comparison Program in Non-Gynecologic Cytopathology to appropriately categorize lymphoproliferative lesions based solely on cytomorphologic criteria. Laboratory responses for lymph node aspirates were examined. All responses were based on review of glass slides without ancillary immunologic or molecular data available. The benchmarking data provided for each specific diagnosis were analyzed, with a focus on the performance for evaluation of lymphoproliferative lesions. Based on morphology alone, responses for lymph node aspirates in the Non-Gynecologic Cytopathology program were correct to the exact reference diagnosis for 87.1% of Hodgkin lymphoma. Non-Hodgkin lymphoma was identified in 69.5% of the large cell non-Hodgkin lymphoma cases, of which 66.8% were correctly classified as large cell type. Non-Hodgkin lymphoma was identified in 68.1% of non-Hodgkin lymphoma, other than large cell cases, and of these, 94.7% were identified as other than large cell type. The spectrum of specific responses was consistent for lymphoproliferative lesions, with a reasonable differential diagnosis based on cytomorphology alone, which, in practice, facilitates the appropriate choice of immunophenotypic markers and other ancillary studies.

    Full Text Available Background. Epstein-Barr virus- (EBV- associated lymphoproliferative disease (LPD is a rare condition, usually occurring in immunocompromised patients. We report a case of EBV-associated LPD in a patient with severe celiac disease, the first report to describe this syndrome in a patient with this diagnosis. Case Summary. A 69-year-old Caucasian woman with recent diagnosis of celiac sprue presented to our hospital with persistent diarrhea, abdominal pain, weight loss, and fatigue despite adherence to gluten-free diet for a number of weeks prior to presentation. She underwent evaluation for occult malignancy and was found to have diffuse intra-abdominal mesenteric lymphadenopathy on CT scan. Biopsy of mesenteric nodes revealed an EBV positive, CD20 positive mixed lymphoproliferative process with T-cell predominance, but without a monoclonal cell population felt to be consistent with EBV-associated LPD. Bone marrow biopsy revealed hemophagocytic lymphohistiocytosis, complicating her course. She was treated with steroids and rituximab but continued to decline, eventually developing MSSA bacteremia and succumbing to her disease. Conclusion. To our knowledge, this is the first report of the constellation of celiac sprue, EBV-associated LPD, and hemophagocytic lymphohistiocytosis. Providers caring for patients with severe, uncontrolled celiac disease and adenopathy should consider EBV-associated LPD.

    Full Text Available Abstract Background Post-transplant lymphoproliferative disorder (PTLD is a complication of solid organ and allogeneic hematopoietic stem cell transplantation (HSCT; following autologous HSCT only rare cases of PTLD have been reported. Here, a case of Hodgkin's disease (HD, as unusual presentation of PTLD after autologous HSCT for malignant glioma is described. Case presentation 60-years old man affected by cerebral anaplastic astrocytoma underwent subtotal neurosurgical excision and subsequent high-dose chemotherapy followed by autologous HSCT. During the post HSCT course, cranial irradiation and corticosteroids were administered as completion of therapeutic program. At day +105 after HSCT, the patient developed HD, nodular sclerosis type, with polymorphic HD-like skin infiltration. Conclusion The clinical and pathological findings were consistent with the diagnosis of PTLD.

    Eosinophilic ulcer of the oral mucosa (EUOM) is a very rare, benign, self-limiting ulcerative lesion of the oral cavity of unknown pathogenesis, and belongs to the same spectrum of CD30(+) T-cell lymphoproliferative disease (LPD) of the oral mucosa. The etiology and pathogenesis of the disease are unknown. We report two cases in children who were initially diagnosed with EUOM and CD30(+) T-cell LPD, respectively. However, retrospective analysis revealed that a majority of infiltrated atypical T cells were positive for Epstein-Barr virus (EBV). The present cases suggest that the pathogenesis and etiology of EUOM or CD30(+) T-cell LPD occurring in children are different from those in adults. EUOM or CD30(+) T-cell LPD in children is a manifestation of EBV-positive T-cell LPD, and should therefore be distinguished from the disease in adults.

  5. Minimal disease detection of B-cell lymphoproliferative disorders by flow cytometry: multidimensional cluster analysis.

    2012-04-01

    Flow cytometric analysis of cell suspensions involves the sequential 'registration' of intrinsic and extrinsic parameters of thousands of cells in list mode files. Thus, it is almost irresistible to describe phenomena in numerical terms or by 'ratios' that have the appearance of 'accuracy' due to the presence of numbers obtained from thousands of cells. The concepts involved in the detection and characterization of B cell lymphoproliferative processes are revisited in this paper by identifying parameters that, when analyzed appropriately, are both necessary and sufficient. The neoplastic process (cluster) can be visualized easily because the parameters that distinguish it form a cluster in multidimensional space that is unique and distinguishable from neighboring clusters that are not of diagnostic interest but serve to provide a background. For B cell neoplasia it is operationally necessary to identify the multidimensional space occupied by a cluster whose kappa:lambda ratio is 100:0 or 0:100. Thus, the concept of kappa:lambda ratio is without meaning and would not detect B cell neoplasia in an unacceptably high number of cases.

    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

    2000-01-01

    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.

    Posttransplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of hematolymphoid proliferations arising in the context of chronic immunosuppression. The common and indolent B-cell lymphomas, including extranodal marginal zone lymphomas (ENMZLs) of mucosa-associated lymphoid tissue (MALT), are excluded from the category of PTLD in the current World Health Organization classification. We report a case of Epstein-Barr virus (EBV)-positive bronchial-associated lymphoid tissue (BALT) lymphoma involving the lungs of a transplant patient. Aside from history of cardiac transplant, young patient age, and EBV positivity, the histopathologic findings were indistinguishable from usual BALT lymphoma. We review the literature of ENMZL occurring in immunocompromised patients and present this case for consideration that this specific entity is a PTLD. We believe that additional studies might lend strength to the hypothesis that this particular group of EBV-positive, posttransplant ENMZLs merits classification and management as PTLDs. © American Society for Clinical Pathology, 2017.

    2015-01-01

    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.

    The incidence of B-cell chronic lymphoproliferative disorders (B-CLPDs) is significantly lower in China than that in western countries. There have been studies involving small cohorts with conflicting results regarding the spectrum of B-CLPDs in China, and the types and immunophenotyping of B-CLPDs in China remain largely unexplored. We conducted a retrospective analysis of 653 cases of B-CLPDs seen in our centre from 2011 to 2015. Four-colour flow cytometry was used to determine the expression of each immunological marker, and the diagnostic values of the immunological markers were also investigated. Chronic lymphocytic leukaemia (CLL) was the most common type of B-CLPD, which was consistent with that in west countries. However, the proportions of CLL (55.9%), follicular lymphoma (2.6%), and hairy cell leukaemia (0.2%) were lower, while the proportion of lymphoplasmacytic lymphoma/WaldenstrÖm macroglobulinaemia (5.4%) was higher in China, as compared with western countries. With respect to immunophenotypic characteristics, CD23 (31.7%) was more frequently expressed in mantle cell lymphoma (MCL) in our cohort than that in western countries. Immunophenotyping was useful in differentiating MCL from CLL or B-cell prolymphocytic leukaemia and lymphoplasmacytic lymphoma/WaldenstrÖm macroglobulinaemia from splenic marginal zone lymphoma. CD200 was of better diagnostic performance (accuracy: 94.6%) in differentiating CLL from MCL compared with CD23 (accuracy: 93.3%). Some cases of B-CPLDs, however, had no definite diagnoses, which were diagnosed as CD5 + B-CPLDs unclassified (7.7%) and CD5 - B-CPLDs unclassified (15.8%). This is the largest study that systematically explores the spectrum and immunophenotyping of B-CLPDs in Asia, confirming that spectrum of B-CLPDs in China was different from that in western countries. The immunophenotypic features of B-CLPDs were similar between China and western countries, although a few disparities exist. Cases with no definite

    Eighty-three people were diagnosed with a lymphoproliferative disorder, of whom 6 had known Type 2 diabetes. Fifty-three people without known diabetes were screened by HbA1c and random venous plasma glucose. All patients (n = 34 subsequently prescribed HDS checked capillary blood glucose (CBG pre-breakfast and pre-evening meal. Treatment algorithms used initiation and/or dose titration of gliclazide or human NPH insulin, aiming for pre-meal CBG 5–11 mmol/l. Type 2 diabetes was identified in 4/53 people screened (7.5%. Of 34 people treated with HDS, 17 (44% developed SIH/SID. All 7 people with Type 2 diabetes developed SIH and 3 required insulin. Of 27 people without known diabetes, 8 (30% developed SID and 1 required insulin. Pre-treatment HbA1c was higher in people who developed SID compared to those that did not (p = 0.002. This is the first report of a SID/SIH detection and treatment protocol for use in people with lymphoproliferative disorders receiving intermittent HDS, demonstrating its feasibility and safety.

    Objectives: To assess the value of dynamic contrast-enhanced MR imaging (DCE-MRI) in differentiating benign from malignant orbital lymphoproliferative disorders (OLPDs). Methods: Thirty-nine patients with orbital lymphoproliferative disorders (21 malignant and 18 benign) underwent DCE-MRI scan for pre-treatment evaluation from March 2013 to December 2015. Both semi-quantitative (TTP, AUC, Slope max ) and quantitative (K trans , k ep , v e ) parameters were calculated, and compared between two groups. Receiver operating characteristic (ROC) curve analyses were used to determine the diagnostic value of each significant parameter. Results: Malignant OLPDs showed significantly higher k ep , lower v e , and lower AUC than benign OLPDs, while no significant differences were found on K trans , TTP and Slope max . ROC analyses indicated that v e exhibited the best diagnostic performance in predicting malignant OLPDs (cutoff value, 0.211; area under the curve, 0.896; sensitivity, 76.2%; specificity, 94.9%), followed by k ep (cutoff value, 0.853; area under the curve, 0.839; sensitivity, 85.7%; specificity, 89.9%). Conclusion: DCE-MRI and specially its derived quantitative parameters of k ep and v e are promising metrics for differentiating malignant from benign OLPDs.

    Full Text Available Multicentric Castleman's disease (MCD is lymphoproliferative disorder characterized by systemic inflammatory symptoms such as fever and weight loss. Human herpes virus-8 (HHV-8 is thought to be a causable pathogen in all HIV-positive and some HIV-negative MCD patients. Furthermore, the term idiopathic MCD (iMCD was recently proposed to represent a group of HIV-negative and HHV-8-negative patients with unknown etiologies. Although the international diagnostic criteria for iMCD require exclusion of infection-related disorders, autoimmune/autoinflammatory diseases and malignant/lymphoproliferative disorders to make an iMCD diagnosis, the relationships and differences between these disorders and MCD have not yet been clarified. We recently reported the first case of MCD with autoimmune lymphoproliferative syndrome (ALPS. Although ALPS was included in the iMCD exclusion criteria as an autoimmune/autoinflammatory disease according to the international diagnostic criteria, there is a lack of evidence on the association between MCD and ALPS. In this study, we review the recent understanding of MCD and discuss the possible association between MCD with ALPS.

    2006-01-01

    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.

    B-chronic lymphocytic leukemia CLL, a neoplastic clonal disorder with monomorphous small B lymphocytes with scanty cytoplasm and clumped chromatin, can be morphologically differentiated in typical and atypical forms with different prognosis: Smudge cells (Gumprecht's shadows) are one of the well-known features of the typical CLL and are much less inconsistent in other different types CLPD. Abbott Cell-Dyn Sapphire uses the fluorescence after staining with the DNA fluorochrome propidium iodide for the measurement of nucleated red blood cells (NRBCs) and nonviable cells (FL3+ cell fraction): We have studied the possible correlation between presence and number of morphologically identifiable smudge cells on smears and the percentage of nonviable cells produced by Cell-Dyn Sapphire. 305 blood samples from 224 patients with B-cell lymphoproliferative disorders and 40 healthy blood donors were analyzed by CBC performed by Cell-Dyn Sapphire, peripheral blood smear, and immunophenotype characterization. FL3+ fraction in CLPD directly correlated with the percentage of smudge cells and is significantly increased in patients with typical B-CLL. This phenomenon is much less evident in patients with atypical/mixed B-CLL and B-NHL. In small laboratories without FCM and cytogenetic, smudge cells%, can be utilized as a preliminary diagnostic and prognostic tool in differential diagnosis of CLPD. © 2014 John Wiley & Sons Ltd.

    Epstein-Barr virus-associated hemophagocytic syndrome (EBV-AHS) is often associated with fatal infectious mononucleosis. However, the animal model for EBV-AHS has not been developed. We reported the first animal model for EBV-AHS using rabbits infected with EBV-related herpesvirus of baboon (HVP). Eleven of 13 (85%) rabbits inoculated intravenously with HVP-producing cells developed fatal lymphoproliferative disorders (LPD) between 22 and 105 days after inoculation. LPD was also accompanied by hemophagocytic syndrome (HPS) in nine of these 11 rabbits. The peroral spray of cell-free HVP induced the virus infection with increased anti-EBV-viral capsid antigen-IgG titers in three of five rabbits, and two of these three infected rabbits died of LPD with HPS. Autopsy revealed hepatosplenomegaly and swollen lymph nodes. Atypical lymphoid T cells expressing EBV-encoded small RNA-1 infiltrated diffusely in many organs, frequently involving the lymph nodes, spleen, and liver. Hemophagocytic histiocytosis was observed in the lymph nodes, spleen, bone marrow, and thymus. HVP-DNA was detected in the tissues and peripheral blood from the infected rabbits by polymerase chain reaction or Southern blot analysis. Reverse transcriptase-polymerase chain reaction revealed both HVP-EBNA1 and HVP-EBNA2 transcripts, suggesting latency type III infection. These data indicate that the high rate of rabbit LPD with HPS induction is caused by HVP. This system is useful for studying the pathogenesis, prevention, and treatment of human EBV-AHS.

    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.

    Waldenström's macroglobulinemia (WM) is a clonal B-cell lymphoproliferative disorder (LPD) of post-germinal center nature. Despite the fact that the precise molecular pathway(s) leading to WM remain(s) to be elucidated, a hallmark of the disease is the absence of the immunoglobulin heavy chain class switch recombination. Using two-dimensional gel electrophoresis, we compared proteomic profiles of WM cells with that of other LPDs. We were able to demonstrate that WM constitutes a unique proteomic entity as compared with chronic lymphocytic leukemia and marginal zone lymphoma. Statistical comparisons of protein expression levels revealed that a few proteins are distinctly expressed in WM in comparison with other LPDs. In particular we observed a major downregulation of the double strand repair protein Ku70 (XRCC6); confirmed at both the protein and RNA levels in an independent cohort of patients. Hence, we define a distinctive proteomic profile for WM where the downregulation of Ku70—a component of the non homologous end-joining pathway—might be relevant in disease pathophysiology

    Posttransplant lymphoproliferative disorders (PTLDs) are a diverse group of lymphoid or plasmacytic proliferations frequently driven by Epstein-Barr virus (EBV). EBV-negative PTLDs appear to represent a distinct entity. This report describes an unusual case of a 33-year-old woman that developed a monomorphic EBV-negative PTLD consistent with diffuse large B-cell lymphoma (DLBCL) 13 years after heart-lung transplant. Histological examination revealed marked pleomorphism of the malignant cells including nodular areas reminiscent of classical Hodgkin lymphoma (cHL) with abundant large, bizarre Hodgkin-like cells. By immunostaining, the malignant cells were immunoreactive for CD45, CD20, CD79a, PAX5, BCL6, MUM1, and p53 and negative for CD15, CD30, latent membrane protein 1 (LMP1), and EBV-encoded RNA (EBER). Flow cytometry demonstrated lambda light chain restricted CD5 and CD10 negative B-cells. Fluorescence in situ hybridization studies (FISH) were negative for cMYC , BCL2, and BCL6 rearrangements but showed deletion of TP53 and monosomy of chromosome 17. Next-generation sequencing studies (NGS) revealed numerous genetic alterations including 6 pathogenic mutations in ASXL1, BCOR, CDKN2A, NF1, and TP53 (x2) genes and 30 variants of unknown significance (VOUS) in ABL1, ASXL1, ATM, BCOR, BCORL1, BRNIP3, CDH2, CDKN2A, DNMT3A, ETV6, EZH2, FBXW7, KIT, NF1, RUNX1, SETPB1, SF1, SMC1A, STAG2, TET2, TP53, and U2AF2.

    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

    Full Text Available Human herpesvirus 6A and 6B (HHV-6A and HHV-6B have been noted since their discovery for their T-lymphotropism. Although it has proven difficult to determine the extent to which HHV-6A and HHV-6B are involved in the pathogenesis of many diseases, evidence suggests that primary infection and reactivation of both viruses may induce or contribute to the progression of several lymphoproliferative disorders, ranging from benign to malignant and including infectious mononucleosis-like illness, drug induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DIHS/DRESS, and nodular sclerosis Hodgkin’s lymphoma. Herein, we discuss the conditions associated with the lymphoproliferative capacity of HHV-6, as well as the potential mechanisms behind them. Continued exploration on this topic may add to our understanding of the interactions between HHV-6 and the immune system and may open the doors to more accurate diagnosis and treatment of certain lymphoproliferative disorders.

    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.

  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

    2010-03-01

    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.

    Fluorine-18 fluorodeoxyglucose (18F-FDG)-positron emission tomography (PET) is a recommended standard in the staging and response assessment of 18F-FDG-avid lymphoma. Posttransplant lymphoproliferative disorder (PTLD) can be detected by 18F-FDG-PET at diagnosis with high sensitivity and specificity. However, the role of response assessment by end-of-treatment (EOT) PET has only been addressed in small case series. We performed a retrospective, multicenter study of 37 patients with CD20-positive PTLD after solid organ transplantation treated with uniform, up-to-date, first-line protocols in the prospective German PTLD registry who had received EOT 18F-FDG-PET between 2006 and 2014. Median follow-up was 5.0 years. Any nonphysiological 18F-FDG uptake (Deauville score greater 2) was interpreted as PET-positive. By computed tomography (CT) final staging, 18 of 37 patients had a complete response, 18 had a partial response and 1 patient had stable disease. EOT PET was negative in 24 of 37 patients and positive in 13 of 37 patients. The positive predictive value of EOT PET for PTLD relapse was 38%, and the negative predictive value was 92%. Time to progression (TTP) and progression-free-survival were significantly longer in the PET negative group (P = 0.019 and P = 0.013). In the 18 patients in a partial response by CT staging, we noted highly significant differences in overall survival (P = 0.001), time to progression (P = 0.007), and progression-free survival (P < 0.001) by EOT PET. Even without baseline imaging, EOT PET in PTLD identifies patients at low risk of relapse and offers clinically relevant information, particularly in patients in a partial remission by CT staging.

  15. EXPRESSION OF A NEW A3 ANTIGEN IN THE CELLS OF PATIENTS WITH VARIOUS LYMPHOPROLIFERATIVE DISEASES

    2014-01-01

    Full Text Available We have conducted a study of a novel monoclonal A3 antibody raised by means of hybridoma biotechnology. The study was performed with malignant cells of the patients with various lymphoproliferative disorders, and persons with nonmalignant diseases, as compared with intact lymphocytes from healthy people,using a method of immunocytochemical staining and indirect immunofluorescence technique. It was found that in cases of lymphoproliferative diseases with low proliferation rates, as based on the numbers of Ki-67 positive cells, as well as in non-malignant blood diseases, the A3 antigen was localized in nucleoli, and it was visualized as focal fluorescence. In malignant lymphoproliferative diseases with high proliferation indexes, the number of brightly fluorescent foci is observed, with formation of necklace-like structures within the nucleolar structures. The obtained data point to a diagnostic significance of A3 Mab in assessment of cellular proliferative rates in patients with various lymphoproliferative diseases. It was established that, in contrast to Ki-67, the proliferation stage could be determined for each cell, according to the number of fuorescent foci in nucleoli. This specific property of the A3 antigen points to its significance for diagnostics and malignancy staging of lymphoproliferative disorders.

    Allogeneic hematopoietic stem cell transplantation is a successful treatment for hematologic malignancies and a variety of genetic and metabolic disorders. In the period following stem cell transplantation, the immune-compromised milieu allows opportunistic pathogens to thrive. Epstein-Barr virus-associated post-transplant lymphoproliferative disease can be a life-threatening complication for transplanted patients because of suppressed T-cell-mediated immunity. We analyzed possible risk factors associated with post-transplant lymphoproliferative disease in a cohort of over 1,000 patients. The incidence of post-transplant lymphoproliferative disease was 4%. Significant risk factors identified by multivariate analysis were: human leukocyte antigen-mismatch (PEpstein-Barr virus mismatch recipient-/donor+ (Pdisease grade II to IV (P=0.006), pre-transplant splenectomy (P=0.008) and infusion of mesenchymal stromal cells (P=0.015). The risk of post-transplant lymphoproliferative disease has increased in more recent years, from less than 2% before 1998 to more than 6% after 2011. Additionally, we show that long-term survival of patients with post-transplant lymphoproliferative disease is poor despite initial successful treatment. The 3-year survival rate among the 40 patients with post-transplant lymphoproliferative disease was 20% as opposed to 62% among patients without post-transplant lymphoproliferative disease (Pdisease after transplantation in need of pre-emptive measures.

    Abnormal Uterine Bleeding (AUB) is a frequent cause of visits to the emergency department and a major reason for concern among adolescents and their families. The most common cause of AUB, in otherwise healthy adolescents, is ovulatory dysfunction, although 5-36% of adolescents who present with heavy menstrual bleeding, have an underlying bleeding disorder (BD). The most common form of BDs is von Willebrand Disease, reflecting 13% of adolescents with AUB. Management of AUB depends on the underlying etiology, the bleeding severity, as well as the need for hospitalization. Treatment of adolescents with an underlying coagulopathy depends on the severity of the BD, while therapeutic interventions are summarized in supportive measures, hormonal treatments (e.g. Combined Oral Contraceptives), non-hormonal treatments (e.g. tranexamic acid and desmopressin), surgical options (e.g. dilatation & curettage) and treatment options in specific conditions.

    A patient with autoimmune lymphoproliferative disorder (ALPS) developed IgG4-related disease. In retrospect, he had high levels of serum IgG4 for several years prior to presenting with IgG4-related pancreatitis. These high IgG4 levels were masked by hypergammaglobulinemia, a common feature of ALPS. We next screened 18 ALPS patients; four of them displayed increased levels of IgG4. Hence, IgG4-related disease should be considered in ALPS patients, especially in those manifesting lymphocytic organ infiltration or excessive hypergammaglobulinaemia. Screening of IgG4-related disease patients for ALPS-associated mutations would provide further information on whether this disease could be a late-onset atypical presentation of ALPS.

    Systemic Epstein-Barr virus-positive T-cell lymphoproliferative childhood disease is an extremely rare disorder and classically arises following primary acute or chronic active Epstein-Barr virus infection. It is characterized by clonal proliferation of Epstein-Barr virus-infected T-cells with an activated cytotoxic phenotype. This disease has a rapid clinical course and is more frequent in Asia and South America, with relatively few cases being reported in Western countries. The clinical and pathological features of the disease overlap with other conditions including infectious mononucleosis, chronic active Epstein-Barr virus infection, hemophagocytic lymphohistiocytosis and natural killer cell malignancies. We describe the rare case of systemic Epstein-Barr virus-positive T-cell lymphoproliferative childhood disease in a 16-year-old Malay boy. He presented with a six-month history of fever and cough, with pulmonary and mediastinal lymphadenopathy and severe pancytopenia. Medium- to large-sized, CD8+ and Epstein-Barr virus-encoded RNA-positive atypical lymphoid cells were present in the bone marrow aspirate. He subsequently developed fatal virus-associated hemophagocytic syndrome and died due to sepsis and multiorgan failure. Although systemic Epstein-Barr virus-positive T-cell lymphoproliferative childhood disease is a disorder which is rarely encountered in clinical practice, our case report underlines the importance of a comprehensive diagnostic approach in the management of this disease. A high level of awareness of the disease throughout the diagnosis process for young patients who present with systemic illness and hemophagocytic syndrome may be of great help for the clinical diagnosis of this disease.

    2012-01-01

    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

    Epstein-Barr virus (EBV)-associated T- or natural killer (NK)-cell lymphoproliferative disease (LPD) is a heterogeneous group of disorders characterized by chronic proliferation of EBV-infected lymphocytes. Patients may present with severe skin manifestations, including hypersensitivity to mosquito bites (HMB) and hydroa vacciniforme (HV)-like eruption, which are characterized by blister formation and necrotic ulceration. Skin biopsy specimens show inflammatory reactions comprising EBV-infected lymphocytes. However, blister fluids have not been fully assessed in patients with this disease. Blister fluids were collected from three patients with EBV-associated LPD: two with HMB and one with HV. Immunophenotyping of blister lymphocytes and measurement of tumor necrosis factor (TNF)-α in blister fluids were performed. The patients with HMB and HV exhibited markedly increased percentages of NK and γδ T cells, respectively, in both peripheral blood and blister fluids. These NK and γδ T cells strongly expressed the activation marker human leukocyte antigen-DR and were considered to be cellular targets of EBV infections. TNF-α was highly elevated in all blister fluids. Severe local skin reactions of EBV-associated LPD may be associated with infiltrating EBV-infected lymphocytes and a high TNF-α concentration in blister fluids. © 2018 Japanese Dermatological Association.

     The objective of this analysis was to investigate prognostic factors that influence the outcome of Epstein-Barr virus (EBV)-related posttransplant lymphoproliferative disorder (PTLD) after a rituximab-based treatment in the allogeneic hematopoietic stem cell transplant (HSCT) setting.  A total of 4466 allogeneic HSCTs performed between 1999 and 2011 in 19 European Group for Blood and Marrow Transplantation centers were retrospectively analyzed for PTLD, either biopsy-proven or probable disease.  One hundred forty-four cases of PTLD were identified, indicating an overall EBV-related PTLD frequency of 3.22%, ranging from 1.16% for matched-family donor, 2.86% for mismatched family donor, 3.97% in matched unrelated donors, and 11.24% in mismatched unrelated donor recipients. In total, 69.4% patients survived PTLD. Multivariable analysis showed that a poor response of PTLD to rituximab was associated with an age ≥30 years, involvement of extralymphoid tissue, acute GVHD, and a lack of reduction of immunosuppression upon PTLD diagnosis. In the prognostic model, the PTLD mortality increased with the increasing number of factors: 0-1, 2, or 3 factors being associated with mortality of 7%, 37%, and 72%, respectively (P disease, and acute graft-vs-host disease predicted poor outcome.

  9. Deregulated expression of HDAC9 in B cells promotes development of lymphoproliferative disease and lymphoma in mice

    Full Text Available Histone deacetylase 9 (HDAC9 is expressed in B cells, and its overexpression has been observed in B-lymphoproliferative disorders, including B-cell non-Hodgkin lymphoma (B-NHL. We examined HDAC9 protein expression and copy number alterations in primary B-NHL samples, identifying high HDAC9 expression among various lymphoma entities and HDAC9 copy number gains in 50% of diffuse large B-cell lymphoma (DLBCL. To study the role of HDAC9 in lymphomagenesis, we generated a genetically engineered mouse (GEM model that constitutively expressed an HDAC9 transgene throughout B-cell development under the control of the immunoglobulin heavy chain (IgH enhancer (Eμ. Here, we report that the Eμ-HDAC9 GEM model develops splenic marginal zone lymphoma and lymphoproliferative disease (LPD with progression towards aggressive DLBCL, with gene expression profiling supporting a germinal center cell origin, as is also seen in human B-NHL tumors. Analysis of Eμ-HDAC9 tumors suggested that HDAC9 might contribute to lymphomagenesis by altering pathways involved in growth and survival, as well as modulating BCL6 activity and p53 tumor suppressor function. Epigenetic modifications play an important role in the germinal center response, and deregulation of the B-cell epigenome as a consequence of mutations and other genomic aberrations are being increasingly recognized as important steps in the pathogenesis of a variety of B-cell lymphomas. A thorough mechanistic understanding of these alterations will inform the use of targeted therapies for these malignancies. These findings strongly suggest a role for HDAC9 in B-NHL and establish a novel GEM model for the study of lymphomagenesis and, potentially, preclinical testing of therapeutic approaches based on histone deacetylase inhibitors.

    The obsessive-compulsive (OC) spectrum has been discussed in the literature for two decades. Proponents of this concept propose that certain disorders characterized by repetitive thoughts and/or behaviors are related to obsessive-compulsive disorder (OCD), and suggest that such disorders be grouped together in the same category (i.e. grouping, or "chapter") in DSM. This article addresses this topic and presents options and preliminary recommendations to be considered for DSM-V. The article builds upon and extends prior reviews of this topic that were prepared for and discussed at a DSM-V Research Planning Conference on Obsessive-Compulsive Spectrum Disorders held in 2006. Our preliminary recommendation is that an OC-spectrum grouping of disorders be included in DSM-V. Furthermore, we preliminarily recommend that consideration be given to including this group of disorders within a larger supraordinate category of "Anxiety and Obsessive-Compulsive Spectrum Disorders." These preliminary recommendations must be evaluated in light of recommendations for, and constraints upon, the overall structure of DSM-V. (c) 2010 Wiley-Liss, Inc.

    To evaluate risks of hematopoietic and lymphoproliferative malignancies among medical workers exposed to protracted low-to-moderate-dose radiation exposures, a follow-up investigation was conducted in a nation wide cohort of U. S. radiologic technologists. eligible for this study were 71.894 technologists (78% female) certified for at least 2 years during 1926-82, who had responded to a baseline mail questionnaire during 1983-89, were cancer-free except for non-melanoma skin cancer at completion of the questionnaire, and completed a second questionnaire during 1994-98 or died through August 1998. There were 241 technologists with hematopoietic or lymphoproliferative malignancies, including 41 with leukemia subtypes associated with radiation exposures (specifically acute myeloid, acute lymphoid and chronic myeloid leukemias, hereafter designated radiogenic leukemias), 23 with chronic lymphocytic leukemia, 28 with multiple myeloma, 118 with non-Hodgkin lymphoma, and 31 with Hodgkin lymphoma. Of the 241 hematopoietic or lymphoproliferative malignancies identified among radiologic technologists, 85 percent were confirmed by medical records or death certificates, including 98 percent of radiogenic leukemia. Risks of the hematopoietic or lymphoproliferative malignancies were evaluated in relation to questionnaire-derived information on employment as a radiologic technologist, including procedures, work practices, and protective measures. cox proportional hazards regression analysis was used to compute relative risks and 95% confidence intervals, using age at diagnosis as the response, stratifying at baseline for birth cohort in 5-year intervals, and adjusting for potential confounding. Risks were not increased for any of the hematopoietic or lymphoproliferative neoplasms according to year first worked or total duration of years worked as radiologic technologist. For the combined radiogenic leukemias, risks rose significantly with an increasing number of years worked

    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 litera...

    2011-01-01

    OBJECTIVE: To summarize Cochrane reviews of acupuncture for neurological disorders, and characteristics of included reviews and studies.DATA SOURCES: A computer-based online search of the Cochrane Library (Issue 7 of 12, July 2010) was performed with the key word "acupuncture" and systematic evaluations for acupuncture for neurological disorders were screened.STUDY SELECTION: Systematic reviews on acupuncture in the treatment of neurological disorders were included, and the characteristics of these reviews were analyzed based on methods recommended by the Cochrane collaboration.MAIN OUTCOME MEASURES: Basic characteristics, methodological quality, main reasons for excluding trials, results and conclusions of Cochrane reviews were assessed.RESULTS: A total of 18 Cochrane systematic reviews were included, including 13 completed reviews and five research protocols. The 13 completed reviews involved 111 randomized controlled trials, including 43 trials (38.7%) conducted in China, 47 trials (42.3%) using sham-acupuncture or placebo as control, 15 trials (13.5%) with relatively high quality, 91 trials (81.9%) reporting data on follow-up. Primary outcomes used in the Cochrane reviews were reported by 65 trials (58.6%), and adverse events were reported in 11 trials (9.9%). Two hundred and eighty three trials were excluded. Two reviews on headache suggested that acupuncture is a valuable non-drug treatment for patients with chronic or recurrent headache, and has better curative effects on migraine compared with preventative drug treatment. CONCLUSION: Of the Cochrane reviews on acupuncture in the treatment of neurological disorders, two reviews evaluating the efficacy of acupuncture in treating headaches drew positive conculsions, while other reviews did not obtain positive conclusions due to a small sample size or low methodological quality. The methodological quality of acupuncture trials needs further improvement.

    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. © 2014 The Authors.

    Chemotherapy-induced neutropenia is a major risk factor for infection-related morbidity and mortality and also a significant dose-limiting toxicity in cancer treatment. Patients developing severe (grade 3/4) or febrile neutropenia (FN) during chemotherapy frequently receive dose reductions and/or delays to their chemotherapy. This may impact the success of treatment, particularly when treatment intent is either curative or to prolong survival. In Europe, prophylactic treatment with granulocyte-colony stimulating factors (G-CSFs), such as filgrastim (including approved biosimilars), lenograstim or pegfilgrastim is available to reduce the risk of chemotherapy-induced neutropenia. However, the use of G-CSF prophylactic treatment varies widely in clinical practice, both in the timing of therapy and in the patients to whom it is offered. The need for generally applicable, European-focused guidelines led to the formation of a European Guidelines Working Party by the European Organisation for Research and Treatment of Cancer (EORTC) and the publication in 2006 of guidelines for the use of G-CSF in adult cancer patients at risk of chemotherapy-induced FN. A new systematic literature review has been undertaken to ensure that recommendations are current and provide guidance on clinical practice in Europe. We recommend that patient-related adverse risk factors, such as elderly age (≥65 years) and neutrophil count be evaluated in the overall assessment of FN risk before administering each cycle of chemotherapy. It is important that after a previous episode of FN, patients receive prophylactic administration of G-CSF in subsequent cycles. We provide an expanded list of common chemotherapy regimens considered to have a high (≥20%) or intermediate (10-20%) risk of FN. Prophylactic G-CSF continues to be recommended in patients receiving a chemotherapy regimen with high risk of FN. When using a chemotherapy regimen associated with FN in 10-20% of patients, particular attention

    To verify if there are characteristic behaviors of the different diagnosis included in the autism spectrum according to the Differential Assessment of Autism and Other Developmental Disorders (DAADD) and to the Autism Behavior Checklist (ABC). Participants were 45 individuals and their respective speech-language therapists. All therapists are graduate students working with the children for at least 1 year. This time was considered sufficient to the therapists to have the information required by the DAADD questionnaire. It is comprised by 3 protocols specifically designed to children with 2 to 4 years, 4 to 6 years and 6 to 8 years, the same criteria used to separate the research groups, G1, G2 and G3, respectively. Data referring to the ABC were retrieved from the subject's files at the Laboratório de Investigação Fonoaudiológica nos Distúrbios do Espectro do Autismo (Research Laboratory on Language Disorders in the Autism Spectrum) of the School of Medicine, Universidade de São Paulo, where it is routinely applied during the annual assessment. Answers to the different areas of DAADD are similar to the different areas of ABC. These data show data the diagnosis by DAADD is easier in older children. Although there is no significant difference, the large occurrence of Rett's syndrome diagnosis according to the DAADD was associated to higher risk for autism according to the ABC in G1. With increasing age this tendency decreases and either in G2 and G3 Autism is the most frequent diagnosis. Although the results of both questionnaires tend to agree more with increasing age, the DAADD is more sensitive in the different ages while the ABC if more specific only to older children.

    2013-01-01

    Hypersexuality disorder has not been added to the list of psychiatric disorders for the Diagnostic and Statistical Manual of Mental Disorders (DSM) V, to be published in May 2013. The evolution of the concept of hypersexuality disorder and its series of different models call into question the controversial context within which its inclusion is considered for the DSM V. A brief contextual analysis makes clear that the creation of this concept follows moral norms and psychosocial values. The construction of hypersexuality disorder in terms of a diagnostic entity rests on the clash of social forces at play in the development process. This article lays the foundation to contemplate the manner in which entities for psychiatric disorders are constructed.

    1993-03-01

    Extensive recent research supports a proposal that a new eating disorder, binge eating disorder (BED), be included in DSM-IV. BED criteria define a relatively pure group of individuals who are distressed by recurrent binge eating who do not exhibit the compensatory features of bulimia nervosa. This large number of patients currently can only be diagnosed as eating disorder not otherwise specified (EDNOS). Recognizing this new disorder will help stimulate research and clinical programs for these patients. Fairburn et al.'s critique of BED fails to acknowledge the large body of knowledge that indicates that BED represents a distinct and definable subgroup of eating disordered patients and that the diagnosis provides useful information about psychopathology, prognosis, and outcome (Fairburn, Welch, & Hay [in press]. The classification of recurrent overeating: The "binge eating disorder" proposal. International Journal of Eating Disorders.) Against any reasonable standard for adding a new diagnosis to DSM-IV, BED meets the test.

    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.

    @@ Borderline personality disorder (BPD) is a serious Bpersonality disorder characterized by a pervasive pattern of disturbances in mood regulation, impulse control, self-image and interpersonal relationships.1 In the United States, the prevalence of BPD has been estimated at 1%-2% of the general population, 10% of psychiatric outpatients, and 20% of inpatients.2,3 According to the 4th text revision of diagnostic and statistical manual of mental disorders (DSM-Ⅳ-TR),1 about 75% of BPD patients are women. The BPD diagnosis has been associated with heightened risk (8.5% to 10.0% among BPD patients) for completed suicide, a rate almost 50times higher than in the general population.4

  9. MLKL and FADD Are Critical for Suppressing Progressive Lymphoproliferative Disease and Activating the NLRP3 Inflammasome

    Full Text Available MLKL, a key component downstream of RIPK3, is suggested to be a terminal executor of necroptosis. Genetic studies have revealed that Ripk3 ablation rescues embryonic lethality in Fadd- or Caspase-8-deficient mice. Given that RIPK3 has also been implicated in non-necroptotic pathways including apoptosis and inflammatory signaling, it remains unclear whether the lethality in Fadd−/− mice is indeed caused by necropotosis. Here, we show that genetic deletion of Mlkl rescues the developmental defect in Fadd-deficient mice and that Fadd−/−Mlkl−/− mice are viable and fertile. Mlkl−/−Fadd−/− mice display significantly accelerated lymphoproliferative disease characterized by lymphadenopathy and splenomegaly when compared to Ripk3−/− Fadd−/− mice. Mlkl−/−Fadd−/− bone-marrow-derived macrophages and dendritic cells have impaired NLRP3 inflammasome activation associated with defects in ASC speck formation and NF-κB-dependent NLRP3 transcription. Our findings reveal that MLKL and FADD play critical roles in preventing lymphoproliferative disease and activating the NLRP3 inflammasome.

    Full Text Available Abstract Background This article reviews the current debate on developmental trauma disorder (DTD with respect to formalizing its diagnostic criteria. Victims of abuse, neglect, and maltreatment in childhood often develop a wide range of age-dependent psychopathologies with various mental comorbidities. The supporters of a formal DTD diagnosis argue that post-traumatic stress disorder (PTSD does not cover all consequences of severe and complex traumatization in childhood. Discussion Traumatized individuals are difficult to treat, but clinical experience has shown that they tend to benefit from specific trauma therapy. A main argument against inclusion of formal DTD criteria into existing diagnostic systems is that emphasis on the etiology of the disorder might force current diagnostic systems to deviate from their purely descriptive nature. Furthermore, comorbidities and biological aspects of the disorder may be underdiagnosed using the DTD criteria. Summary Here, we discuss arguments for and against the proposal of DTD criteria and address implications and consequences for the clinical practice.

    Histopathology of muscularis externa in primary esophageal motility disorders has been characterized previously. We aimed to correlate the results of high-resolution manometry with those of histopathology. During peroral endoscopic myotomy, peroral esophageal muscle biopsy was performed in patients with primary esophageal motility disorders. Immunohistochemical staining for c-kit was performed to assess the interstitial cells of Cajal (ICCs). Hematoxylin Eosin and Azan-Mallory staining were used to detect muscle atrophy, inflammation, and fibrosis, respectively. Slides from 30 patients with the following motility disorders were analyzed: achalasia (type I: 14, type II: 5, type III: 3), one diffuse esophageal spasm (DES), two outflow obstruction (OO), four jackhammer esophagus (JE), and one nutcracker esophagus (NE). ICCs were preserved in high numbers in type III achalasia (n=9.4±1.2 cells/high power field [HPF]), compared to types I (n=3.7±0.3 cells/HPF) and II (n=3.5±1.0 cells/HPF). Moreover, severe fibrosis was only observed in type I achalasia and not in other types of achalasia, OO, or DES. Four of five patients with JE and NE had severe inflammation with eosinophilic infiltration of the esophageal muscle layer (73.8±50.3 eosinophils/HPF) with no epithelial eosinophils. One patient with JE showed a visceral myopathy pattern. Compared to types I and II, type III achalasia showed preserved ICCs, with variable data regarding DES and OO. In disorders considered as primary esophageal motility disorders, a disease category exists, which shows eosinophilic infiltration in the esophageal muscle layer with no eosinophils in the epithelium. © 2016 John Wiley & Sons Ltd.

    AIM To define clinical criteria to differentiate eosinophilic gastrointestinal disorder (EoGD) in the esophagus. METHODS Our criteria were defined based on the analyses of the clinical presentation of eosinophilic esophagitis (EoE), subepithelial eosinophilic esophagitis (sEoE) and eosinophilic esophageal myositis (EoEM), identified by endoscopy, manometry and serum immunoglobulin E levels (s-IgE), in combination with histological and polymerase chain reaction analyses on esophageal tissue samples. RESULTS In five patients with EoE, endoscopy revealed longitudinal furrows and white plaques in all, and fixed rings in two. In one patient with sEoE and four with EoEM, endoscopy showed luminal compression only. Using manometry, failed peristalsis was observed in patients with EoE and sEoE with some variation, while EoEM was associated with hypercontractile or hypertensive peristalsis, with elevated s-IgE. Histology revealed the following eosinophils per high-power field values. EoE = 41.4 ± 7.9 in the epithelium and 2.3 ± 1.5 in the subepithelium; sEoE = 3 in the epithelium and 35 in the subepithelium (conventional biopsy); EoEM = none in the epithelium, 10.7 ± 11.7 in the subepithelium (conventional biopsy or endoscopic mucosal resection) and 46.8 ± 16.5 in the muscularis propria (peroral esophageal muscle biopsy). Presence of dilated epithelial intercellular space and downward papillae elongation were specific to EoE. Eotaxin-3, IL-5 and IL-13 were overexpressed in EoE. CONCLUSION Based on clinical and histological data, we identified criteria, which differentiated between EoE, sEoE and EoEM, and reflected a different pathogenesis between these esophageal EoGDs.

    Little is known about the epidemiology and health related quality of life (HRQoL) of the new DSM-5 diagnoses, Binge Eating Disorder (BED) and Avoidant/Restrictive Food Intake Disorder (ARFID) in the Australian population. We aimed to investigate the prevalance and burden of these disorders. We conducted two sequential population-based surveys including individuals aged over 15 years who were interviewed in 2014 ( n  = 2732) and 2015 ( n =3005). Demographic information and diagnostic features of DSM-5 eating disorders were asked including the occurrence of regular (at least weekly over the past 3 months) objective binge eating with levels of distress, extreme dietary restriction/fasting for weight/shape control, purging behaviors, overvaluation of shape and/or weight, and the presence of an avoidant/restrictive food intake without overvaluation of shape and/or weight. In 2014 functional impact or role performance was measured with the 'days out of role' question and in 2015, Health Related Quality of Life (HRQoL) was assessed with the Short Form -12 item questionnaire (SF-12v1). The 2014 and 2015 3-month prevalence of eating disorders were: anorexia nervosa-broad 0.4% (95% CI 0.2-0.7) and 0.5% (0.3-0.9); bulimia nervosa 1.1% (0.7-1.5) and 1.2% (0.9-1.7); ARFID 0.3% (0.1-0.5) and 0.3% (0.2-0.6). The 2015 3-month prevalence rates were: BED-broad 1.5% (1.1-2.0); Other Specified Feeding or Eating Disorder (OSFED) 3.2 (2.6-3.9); and Unspecified Feeding or Eating Disorder (UFED) 10.4% (0.9-11.5). Most people with OSFED had atypical anorexia nervosa and majority with UFED were characterised by having recurrent binge eating without marked distress. Eating disorders were represented throughout sociodemographic groups and those with bulimia nervosa and BED-broad had mean weight (BMI, kg/m 2 ) in the obese range. Mental HRQoL was poor in all eating disorder groups but particularly poor for those with BED-broad and ARFID. Individuals with bulimia nervosa, BED

    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.

    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.

    Epstein-Barr virus (EBV) is associated with several life-threatening diseases, such as lymphoproliferative disease (LPD), particularly in immunocompromised hosts. Some categories of primary immunodeficiency diseases (PIDs) including X-linked lymphoproliferative syndrome (XLP), are characterized by susceptibility and vulnerability to EBV infection. The number of genetically defined PIDs is rapidly increasing, and clinical genetic testing plays an important role in establishing a definitive diagnosis. Whole-exome sequencing is performed for diagnosing rare genetic diseases, but is both expensive and time-consuming. Low-cost, high-throughput gene analysis systems are thus necessary. We developed a comprehensive molecular diagnostic method using a two-step tailed polymerase chain reaction (PCR) and a next-generation sequencing (NGS) platform to detect mutations in 23 candidate genes responsible for XLP or XLP-like diseases. Samples from 19 patients suspected of having EBV-associated LPD were used in this comprehensive molecular diagnosis. Causative gene mutations (involving PRF1 and SH2D1A) were detected in two of the 19 patients studied. This comprehensive diagnosis method effectively detected mutations in all coding exons of 23 genes with sufficient read numbers for each amplicon. This comprehensive molecular diagnostic method using PCR and NGS provides a rapid, accurate, low-cost diagnosis for patients with XLP or XLP-like diseases.

    Full Text Available Introduction: Post-transplant lymphoproliferative syndrome (PTLD is a rare and potentially life-threatening complication after liver transplantation. The aim of this study was to analyze the clinicopathologic features related to PTLD in a single institution after liver transplantation. Methods: Observational study where we have retrospectively analyzed 851 cases who underwent liver transplantation. Ten cases have developed PTLD. Their clinical-pathological characteristics and the treatment received have been analyzed. Results: PTLD incidence was 1.2% (10/851. The mean time from liver transplantation to PTLD diagnosis was 36 months (range 1.2 to 144 months. PTLD localization was extranodal in all cases, the most frequent location being intestinal. Seven cases showed a monomorphic lymphoma which in all cases was differentiated B cell lymphomas. Fifty per cent of the series were seropositive for Epstein-Barr virus. Five patients were alive at the time of the review. Among these patients, we observed three cases of complete remission and two cases of disease stabilization. The death rate was higher in the first year after diagnosis of PTLD. Conclusion: PTLD is a rare complication after liver transplantation, but it may pose a threat to the life of a liver transplant recipient. It is essential to identify patients at risk, to establish an early diagnosis and treatment that can change the outcome of the disease.

    To assess mortality related to musculoskeletal (MSK) disorders and rheumatoid arthritis (RA), specifically, among adults (aged ≥ 20 yrs) in southern Sweden using the multiple-cause-of-death approach. All death certificates (DC; n = 201,488) from 1998 to 2014 for adults in the region of Skåne were analyzed when mortality from MSK disorders and RA was listed as the underlying and nonunderlying cause of death (UCD/NUCD). Trends in age-standardized mortality rates (ASMR) were evaluated using joinpoint regression, and associated causes were identified by age- and sex-adjusted observed/expected ratios. MSK (RA) was mentioned on 2.8% (0.8%) of all DC and selected as UCD in 0.6% (0.2%), with higher values among women. Proportion of MSK disorder deaths from all deaths increased from 2.7% in 1998 to 3.1% in 2014, and declined from 0.9% to 0.5% for RA. The mean age at death was higher in DC with mention of MSK/RA than in DC without. The mean ASMR for MSK (RA) was 15.5 (4.3) per 100,000 person-years and declined by 1.1% (3.8%) per year during 1998-2014. When MSK/RA were UCD, pneumonia and heart failure were the main NUCD. When MSK/RA were NUCD, the leading UCD were ischemic heart disease and neoplasms. The greatest observed/expected ratios were seen for infectious diseases (including sepsis) and blood diseases. We observed significant reduction in MSK and RA mortality rates and increase in the mean age at death. Further analyses are required to investigate determinants of these improvements in MSK/RA survival and their potential effect on the Swedish healthcare systems.

  3. Development of a versatile enrichment analysis tool reveals associations between the maternal brain and mental health disorders, including autism

    Science.gov (United States)

    2013-01-01

    Background A recent study of lateral septum (LS) suggested a large number of autism-related genes with altered expression in the postpartum state. However, formally testing the findings for enrichment of autism-associated genes proved to be problematic with existing software. Many gene-disease association databases have been curated which are not currently incorporated in popular, full-featured enrichment tools, and the use of custom gene lists in these programs can be difficult to perform and interpret. As a simple alternative, we have developed the Modular Single-set Enrichment Test (MSET), a minimal tool that enables one to easily evaluate expression data for enrichment of any conceivable gene list of interest. Results The MSET approach was validated by testing several publicly available expression data sets for expected enrichment in areas of autism, attention deficit hyperactivity disorder (ADHD), and arthritis. Using nine independent, unique autism gene lists extracted from association databases and two recent publications, a striking consensus of enrichment was detected within gene expression changes in LS of postpartum mice. A network of 160 autism-related genes was identified, representing developmental processes such as synaptic plasticity, neuronal morphogenesis, and differentiation. Additionally, maternal LS displayed enrichment for genes associated with bipolar disorder, schizophrenia, ADHD, and depression. Conclusions The transition to motherhood includes the most fundamental social bonding event in mammals and features naturally occurring changes in sociability. Some individuals with autism, schizophrenia, or other mental health disorders exhibit impaired social traits. Genes involved in these deficits may also contribute to elevated sociability in the maternal brain. To date, this is the first study to show a significant, quantitative link between the maternal brain and mental health disorders using large scale gene expression data. Thus, the

    Notably absent from the intervention literature are parent training programs targeting school-aged children with autism who have limited communication skills (Tager-Flusberg and Kasari in Autism Res 6:468-478, 2013). Sixty-one children with autism age 5-8 with minimal spontaneous communication received a 6-month social communication intervention including parent training. Parent-child play interactions were coded for parents' strategy implementation and children's time jointly engaged (Adamson et al. in J Autism Dev Disord 39:84-96, 2009). Parents mastered an average of 70% of the strategies. Further analyses indicated some gains in implementation occurred from mere observation of sessions, while the greatest gains occurred in the first month of active coaching and workshops. Children's joint engagement was associated with parents' implementation success across time demonstrating parents' implementation was relevant to children's social engagement.

    Difficult patients are often those who present with a mix of physical and psychiatric symptoms, and seem refractory to usual treatments or reassurance. such patients can include those with personality disorders, those with somatization symptoms; they can come across as entitled, drug-seeking, manipulative, or simply draining to the provider. Such patients are often frequent visitors to Emergency Departments. Other reasons for difficult encounters could be rooted in provider bias or countertransference, rather than sole patient factors. Emergency providers need to have high awareness of these possibilities, and be prepared to manage such situations, otherwise workup can be sub-standard and dangerous medical mistakes can be made.

    With DSM-5, the American Psychiatric Association encourages complementing categorical diagnoses with dimensional severity ratings. We therefore examined the psychometric properties of the DSM-5 Dimensional Anxiety Scales, a set of brief dimensional scales that are consistent in content and structure and assess DSM-5-based core features of anxiety disorders. Participants (285 males, 255 females) completed the DSM-5 Dimensional Anxiety Scales for social anxiety disorder, generalized anxiety disorder, specific phobia, agoraphobia, and panic disorder that were included in previous studies on the scales, and also for separation anxiety disorder, which is included in the DSM-5 chapter on anxiety disorders. Moreover, they completed the Screen for Child Anxiety Related Emotional Disorders Adult version (SCARED-A). The DSM-5 Dimensional Anxiety Scales demonstrated high internal consistency, and the scales correlated significantly and substantially with corresponding SCARED-A subscales, supporting convergent validity. Separation anxiety appeared present among adults, supporting the DSM-5 recognition of separation anxiety as an anxiety disorder across the life span. To conclude, the DSM-5 Dimensional Anxiety Scales are a valuable tool to screen for specific adult anxiety disorders, including separation anxiety. Research in more diverse and clinical samples with anxiety disorders is needed. © 2016 The Authors International Journal of Methods in Psychiatric Research Published by John Wiley & Sons Ltd. © 2016 The Authors International Journal of Methods in Psychiatric Research Published by John Wiley & Sons Ltd.

    Epstein-Barr virus (EBV) reactivation can cause significant morbidity and mortality after allogeneic hematopoietic stem cell transplant. Delays in reconstitution of EBV-specific T lymphocyte activity can lead to life-threatening EBV lymphoproliferative disease (EBV-PTLD). This review highlights recent advances in the understanding of pathophysiology, risk factors, diagnosis, and management of EBV viremia and PTLD. During the past decade, early detection strategies, such as serial measurement of EBV-DNA load, have helped identify high-risk patients and diagnose early lymphoproliferation. The most significant advances have come in the form of innovative treatment options, including manipulation of the balance between outgrowing EBV-infected B cells and the EBV cytotoxic T lymphocyte response, and targeting infected B cells with monoclonal antibodies, chemotherapy, unmanipulated donor lymphocytes, and donor or more recently third-party EBV cytotoxic T lymphocytes. Defining criteria for preemptive therapy remains a challenge. EBV reactivation is a significant complication after stem cell transplant. Continued improvements in risk stratification and treatment options are required to improve the morbidity and mortality caused by EBV-associated diseases. Current approaches use rituximab to deplete B cells or adoptive transfer of EBV cytotoxic T lymphocyte to reconstitute immunity. The availability of rapid EBV-specific T cell products offers the possibility of improved outcomes.

    We report three patients who developed severe supraglottic airway obstruction due to Epstein-Barr virus lymphoproliferative disease following allogeneic bone marrow transplantation. In addition to enlarged pharyngeal lymphoid tissue seen in all three patients, two had supraglottic airway narrowing and two developed pulmonary lymphoproliferative disease. They were treated with unmanipulated T cells or EBV-specific cytotoxic T lymphocytes. Life-threatening upper airway obstruction is a radiologically detectable complication of allogeneic bone marrow transplantation in children. (orig.) With 3 figs., 1 tab., 12 refs.

    Fifty years after the first reports of Epstein-Barr virus (EBV)-associated endemic Burkitt's lymphoma, EBV has emerged as the third most prevalent oncogenic virus worldwide. EBV infection is associated with various malignancies including Hodgkin and non-Hodgkin lymphoma, NK/T-cell lymphoma and nasopharyngeal carcinoma. Despite the highly specific immunologic control in the immunocompetent host, EBV can cause severe complications in the immunocompromised host (namely, post-transplant lymphoproliferative disease). This is particularly a problem in patients with delayed immune reconstitution post-hematopoietic stem cell transplant or solid organ transplant. Despite advances in diagnostic techniques and treatment algorithms allowing earlier identification and treatment of patients at highest risk, mortality rates remain as high as 90% if not treated early. The cornerstones of treatment include reduction in immunosuppression and in vivo B cell depletion with an anti-CD20 monoclonal antibody. However, these treatment modalities are not always feasible due to graft rejection, emergence of graft vs. host disease, and toxicity. Newer treatment modalities include the use of adoptive T cell therapy, which has shown promising results in various EBV-related malignancies. In this article we will review recent advances in risk factors, diagnosis and management of EBV-associated malignancies, particularly post-transplant lymphoproliferative disease. We will also discuss new and innovative treatment options including adoptive T cell therapy as well as management of special situations such as chronic active EBV and EBV-associated hemophagocytic lymphohistiocytosis.

    Full Text Available Background: Eosinophilia has not been reported as a manifestation of a mitochondrial disorder (MID. Here, we report a patient with clinical features suggesting a MID and permanent eosinophilia, multisystem disease, and progressive hyper-creatine-kinase (CK-emia for at least 10 years. Materials and Methods: Methods applied included a clinical exam, blood chemical investigations, electrophysiological investigations, imaging, and invasive cardiological investigations. The patient was repeatedly followed up over several years. He required replacement cardiac surgery. Results: In a 57-year-old male, eosinophilia was first detected at the age of 44 years and has remained almost constantly present until today. In addition to eosinophilia, he developed progressive hyper-CK-emia at the age of 47 years. His history was further positive for hepatopathy, hyperlipidemia, hypothyroidism, renal insufficiency, spontaneous Achilles tendon rupture, double vision, exercise intolerance, muscle aching, mild hypoacusis, sensory neuropathy, seizures, and mitral insufficiency/stenosis requiring valve replacement therapy, oral anticoagulation, and pacemaker implantation. Based on the multisystem nature of his abnormalities and permanent hyper-CK-emia, a MID was suspected. Conclusion: Eosinophilia can be associated with a MID with myopathy, possibly as a reaction to myofiber necrosis. If eosinophilia is associated with progressive hyper-CK-emia and multisystem disease, a MID should be suspected.

    Klotho is a hormone secreted into human cerebrospinal fluid (CSF), plasma and urine that promotes longevity and influences the onset of several premature senescent phenotypes in mice and humans, including atherosclerosis, cardiovascular disease, stroke and osteoporosis. Preliminary studies also suggest that Klotho possesses tumor suppressor properties. Klotho's roles in these phenomena were first suggested by studies demonstrating that a defect in the Klotho gene in mice results in a significant decrease in lifespan. The Klotho-deficient mouse dies prematurely at 8-9 weeks of age. At 4-5 weeks of age, a syndrome resembling human ageing emerges consisting of atherosclerosis, osteoporosis, cognitive disturbances and alterations of hippocampal architecture. Several deficits in Klotho-deficient mice are likely to contribute to these phenomena. These include an inability to defend against oxidative stress in the central nervous system and periphery, decreased capacity to generate nitric oxide to sustain normal endothelial reactivity, defective Klotho-related mediation of glycosylation and ion channel regulation, increased insulin/insulin-like growth factor signaling and a disturbed calcium and phosphate homeostasis accompanied by altered vitamin D levels and ectopic calcification. Identifying the mechanisms by which Klotho influences multiple important pathways is an emerging field in human biology that will contribute significantly to understanding basic physiologic processes and targets for the treatment of complex diseases. Because many of the phenomena seen in Klotho-deficient mice occur in depressive illness, major depression and bipolar disorder represent illnesses potentially associated with Klotho dysregulation. Klotho's presence in CSF, blood and urine should facilitate its study in clinical populations.

    Changes to the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) incorporate the inclusion or modification of six disorders: Autism Spectrum Disorder, Social Anxiety Disorder, Intermittent Explosive Disorder, Disruptive Mood Dysregulation Disorder, Avoidant/Restrictive Food Intake Disorder and Binge Eating Disorder. The objectives of this study were to assess the construct validity and parent-child agreement of these six disorders in the Spanish language Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version (K-SADS-PL-5) in a clinical population of children and adolescents from Latin America. The Spanish version of the K-SADS-PL was modified to integrate changes made to the DSM-5. Clinicians received training in the K-SADS-PL-5 and 90% agreement between raters was obtained. A total of 80 patients were recruited in four different countries in Latin America. All items from each of the six disorders were included in a factor analysis. Parent-child agreement was calculated for every item of the six disorders, including the effect of sex and age. The factor analysis revealed 6 factors separately grouping the items defining each of the new or modified disorders, with Eigenvalues greater than 2. Very good parent-child agreements (r>0.8) were found for the large majority of the items (93%), even when considering the sex or age of the patient. This independent grouping of disorders suggests that the manner in which the disorders were included into the K-SADS-PL-5 reflects robustly the DSM-5 constructs and displayed a significant inter-informant reliability. These findings support the use of K-SADS-PL-5 as a clinical and research tool to evaluate these new or modified diagnoses. Copyright © 2018. Published by Elsevier Ltd.

    Background Celiac disease (CD) is associated with an increased risk of lymphoproliferative malignancy (LPM). It is unknown whether this risk is affected by the results of the follow-up intestinal biopsy, performed to document mucosal healing. Objective To examine the association between mucosal healing in CD and later LPM. Design Population-based cohort study Setting We identified patients with CD from all of Sweden’s 28 pathology departments. Patients Individuals with CD who had a follow-up biopsy after initial diagnosis. Measurements We compared the risk of LPM to that of the general population using expected rates; and through Cox regression we compared the rate of LPM in those with persistent villous atrophy to those with mucosal healing. Results Among 7,625 patients with CD and a follow-up biopsy, persistent villous atrophy was present in 3,308 (43%). The overall risk of LPM was increased compared to the general population (Standardized incidence ratio, SIR 2.81; 95%CI 2.10–3.67), but this increase was greater among those with persistent villous atrophy (SIR 3.78; 95%CI 2.71–5.12) as compared to those with mucosal healing (SIR 1.50; 95%CI 0.77–2.62). Persistent villous atrophy compared to mucosal healing was associated with an increased risk of LPM (Hazard ratio, HR 2.26; 95%CI 1.18–4.34). We found an increased risk of T cell lymphoma (HR 3.51; 95%CI 0.75–16.34), but no excess risk of B cell lymphoma (HR 0.97; 95%CI 0.21–4.49). Limitation We had no data on dietary compliance. Conclusions The increased LPM risk in CD is associated with the results of the follow-up biopsy, with a higher risk among those with persistent villous atrophy. Follow-up biopsy may be a means to effectively stratify CD patients regarding subsequent LPM risk.

    An influence of disorder originated from the substrate/layer interface on electrical properties of CdTe:In layers was investigated by means of the Hall effect and magnetoresistance measurements at low temperatures. An estimation of a scattering rate due to interface induced disorder is given. Characteristic features of a magnetic field dependence of magnetoresistance are explained by an influence of quantum interference of scattered electron waves both in the hopping and the free electron conductivity regimes.

Recruitment through a network of 50 UK child health teams and self-referral. Parents/carers with a child with ASD, aged 2-16 years, completed questionnaires about ASD and some gave professionals' reports about their children. 1000 families registered with ASD-UK in 30 months. Children of families who participated, and of the 208 who chose not to, were found to be very similar on: gender ratio, year of birth, ASD diagnosis and social deprivation score. The reliability of parent-reported ASD diagnoses of children was very high when compared with clinical reports (over 96%); no database child without ASD was identified. A comparison of gender, ASD diagnosis, age at diagnosis, school placement, learning disability, and deprivation score of children and families from ASD-UK with 1084 children and families from Dasl(n)e, and families from population studies, showed that ASD-UK families are representative of families of children with ASD overall. ASD-UK includes families providing parent-reported data about their child and family, who appear to be broadly representative of UK children with ASD. Families continue to join the databases and more than 3000 families can now be contacted by researchers about UK autism research. Published by the BMJ

So, the aim of the current study was to present an appropriate method which could help in increasing the productivity and decreasing the risk factors of ergonomics in socio-technical systems.   Methods: During the present study, a theoretical model was developed to guide the “ergonomic intervention processes” and its evaluation and application was carried out for an educational organization (EO. The faculty members were selected as the subjects of statistical survey and simple random sampling was performed. The level of musculoskeletal disorders was evaluated in control and treatment groups. Comparative analysis of the obtained data was carried out using fuzzy numbers and their level of confinement.   Results: According to the results of present study with the help of ergonomic interventions, an increase in the activity of staff members, increased revenue, expansion of work with the least number of manpower and a decrease in the overall expenses was seen as compared to the base year. In addition, the analysis of questionnaires with fuzzy approach has shown that the level of musculoskeletal disorders in the experimental group was less as compared to that of control group.   Conclusion: The results obtained by the use of macro and micro ergonomic interventions (Total ergonomics have proved that these methods were successful by increasing the innovation and motivation of the staff members to solve the organizational problems as compared to the base year. The decrease of musculoskeletal disorders among the members resulted to an increase of performance in different units of the educational organization.

The lymphoproliferative responses of placental cells were poor to all antigens compared with those of peripheral blood (Candida P PPD P ....003, and 190N P = 0.10). Reduced proliferative capacity of placental mononuclear cells may contribute to heavy parasite colonization of this organ.

    The most common type of ocular lymphoma is non-Hodgkin lymphoma (NHL), categorized into two groups: indolent (slow growing) and aggressive (rapid growing). Differentiating benign reactive lymphoid hyperplasia (RLH) from malignant ocular adnexal lymphoma (OAL) is challenging. Histopathology, immunohistochemistry (IHC) and ow cytometry have been used as diagnostic tools in such cases. In this retrospective case series, from 2002 to 2013 at Farabi Eye Center, 110 patients with ocular lymphoproliferative disease were enrolled. Prevalence, anatomical locations, mean age at diagnosis and the nal diagnosis of the disease with IHC were assessed. Comparison between previous pathologic diagnoses and results of IHC was made. Immunoglobulin light chains and B-cell and T-cell markers and other immuno-phenotyping markers including CD20, CD3, CD5, CD23, CD10, CYCLIND1 and BCL2 were evaluated to determine the most accurate diagnosis. The lymphomas were categorized based on revised European-American lymphoma (REAL) classi cation. Mean age±SD (years) of the patients was 55.6 ±19.3 and 61% were male. Patients with follicular lymphoma, large B-cell lymphoma or chronic lymphocytic leukemia/small cell lymphoma (CLL/SLL) tended to be older. Nine patients with previous diagnoses of low grade B-cell lymphoma were re-evaluated by IHC and the new diagnoses were as follows: extranodal marginal zone lymphoma(EMZL) (n=1), SLL(n=1), mantle cell lymphoma (MCL) (n=3), reactive lymphoid hyperplasia RLH (n=2). Two cases were excluded due to poor blocks. Flow cytometry reports in these seven patients revealed SLL with positive CD5 and CD23, MCL with positive CD5 and CyclinD1 and negative CD23, EMZL with negative CD5,CD23 and CD10. One RLH patient was negative for Kappa/Lambda and positive for CD3 and CD20 and the other was positive for all of the light chains, CD3 and CD20. Orbit (49.1%), conjunctiva (16.1%) and lacrimal glands (16.1%) were the most common sites of involvement. Accurate

    Full Text Available Abstract Background Depressive disorder is currently one of the most burdensome disorders worldwide. Evidence-based treatments for depressive disorder are already available, but these are used insufficiently, and with less positive results than possible. Earlier research in the USA has shown good results in the treatment of depressive disorder based on a collaborative care approach with Problem Solving Treatment and an antidepressant treatment algorithm, and research in the UK has also shown good results with Problem Solving Treatment. These treatment strategies may also work very well in the Netherlands too, even though health care systems differ between countries. Methods/design This study is a two-armed randomised clinical trial, with randomization on patient-level. The aim of the trial is to evaluate the treatment of depressive disorder in primary care in the Netherlands by means of an adapted collaborative care framework, including contracting and adherence-improving strategies, combined with Problem Solving Treatment and antidepressant medication according to a treatment algorithm. Forty general practices will be randomised to either the intervention group or the control group. Included will be patients who are diagnosed with moderate to severe depression, based on DSM-IV criteria, and stratified according to comorbid chronic physical illness. Patients in the intervention group will receive treatment based on the collaborative care approach, and patients in the control group will receive care as usual. Baseline measurements and follow up measures (3, 6, 9 and 12 months are assessed using questionnaires and an interview. The primary outcome measure is severity of depressive symptoms, according to the PHQ9. Secondary outcome measures are remission as measured with the PHQ9 and the IDS-SR, and cost-effectiveness measured with the TiC-P, the EQ-5D and the SF-36.

    Full Text Available Interest in preclinical drug development for ovarian cancer has stimulated development of patient-derived xenograft (PDX or tumorgraft models. However, the unintended formation of human lymphoma in severe combined immunodeficiency (SCID mice from Epstein-Barr virus (EBV–infected human lymphocytes can be problematic. In this study, we have characterized ovarian cancer PDXs which developed human lymphomas and explore methods to suppress lymphoproliferative growth. Fresh human ovarian tumors from 568 patients were transplanted intraperitoneally in SCID mice. A subset of PDX models demonstrated atypical patterns of dissemination with mediastinal masses, hepatosplenomegaly, and CD45-positive lymphoblastic atypia without ovarian tumor engraftment. Expression of human CD20 but not CD3 supported a B-cell lineage, and EBV genomes were detected in all lymphoproliferative tumors. Immunophenotyping confirmed monoclonal gene rearrangements consistent with B-cell lymphoma, and global gene expression patterns correlated well with other human lymphomas. The ability of rituximab, an anti-CD20 antibody, to suppress human lymphoproliferation from a patient's ovarian tumor in SCID mice and prevent growth of an established lymphoma led to a practice change with a goal to reduce the incidence of lymphomas. A single dose of rituximab during the primary tumor heterotransplantation process reduced the incidence of CD45-positive cells in subsequent PDX lines from 86.3% (n = 117 without rituximab to 5.6% (n = 160 with rituximab, and the lymphoma rate declined from 11.1% to 1.88%. Taken together, investigators utilizing PDX models for research should routinely monitor for lymphoproliferative tumors and consider implementing methods to suppress their growth.

    2010-01-01

    Summary We hypothesized that sirolimus, an mTOR inhibitor, may be effective in patients with autoimmune lymphoproliferative syndrome (ALPS) and treated patients who were intolerant to or failed other therapies. Four patients were treated for autoimmune cytopenias; all had a rapid complete or near complete response. Two patients were treated for autoimmune arthritis and colitis, demonstrating marked improvement. Three patients had complete resolution of lymphadenopathy and splenomegaly and all patients had a reduction in double negative T cells, a population hallmark of the disease. Based on these significant responses, we recommend that sirolimus be considered as second-line therapy for patients with steroid-refractory disease. PMID:19208097

    2015-01-01

    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.

    Some new theoretical results on the microstructure of models of two-phase disordered media are given, as well as the new quantitative bounds on the thermal conductivity that follows for one such model (randomly centered spherical inclusions). A second set of results is then given for random flights, including random flights with hit expectancy prescribed in a unit hall around the flight origin. Finally, some interesting correspondences are demonstrated, via the Ornstein-Zernike equation, between random-flight results, liquid-state results and percolation-theory results. 27 references, 6 figures, 4 tables

    2001-06-01

    The recognition of the importance of Epstein-Barr virus (EBV) infection, including EBV-associated post-transplant lymphoproliferative disease (PTLD), has led to a new focus on the prevention of this problem. This paper reviews the scientific rationale behind, and clinical experience with, the use of chemoprophylaxis (using acyclovir or ganciclovir) and immunoprophylaxis (using intravenous immunoglobulin) in the prevention of EBV/PTLD. While some centers have already introduced the use of one or both of these agents as standard prophylaxis against the development of this complication, published data in support of these protocols are currently lacking. Well designed clinical trials are necessary to evaluate the potential role of both antiviral and immunoglobulin agents in the prevention of EBV/PTLD in organ transplant recipients.

    An insertional translocation (IT) can result in pure segmental aneusomy for the inserted genomic segment allowing to define a more accurate clinical phenotype. Here, we report on two siblings sharing an unbalanced IT inherited from the mother with a history of learning difficulty. An 8-year-old girl with developmental delay, speech disability, and attention-deficit hyperactivity disorder (ADHD), showed by GTG banding analysis a subtle interstitial alteration in 21q21. Oligonucleotide array comparative genomic hybridization (array-CGH) analysis showed a 4q13.1-q13.3 duplication spanning 8.6 Mb. Fluorescence in situ hybridization (FISH) with bacterial artificial chromosome (BAC) clones confirmed the rearrangement, a der(21)ins(21;4)(q21;q13.1q13.3). The duplication described involves 50 RefSeq genes including the EPHA5 gene that encodes for the EphA5 receptor involved in embryonic development of the brain and also in synaptic remodeling and plasticity thought to underlie learning and memory. The same rearrangement was observed in a younger brother with behavioral problems and also exhibiting ADHD. ADHD is among the most heritable of neuropsychiatric disorders. There are few reports of patients with duplications involving the proximal region of 4q and a mild phenotype. To the best of our knowledge this is the first report of a duplication restricted to band 4q13. This abnormality could be easily missed in children who have nonspecific cognitive impairment. The presence of this behavioral disorder in the two siblings reinforces the hypothesis that the region involved could include genes involved in ADHD. Copyright © 2013 Wiley Periodicals, Inc.

    Chromosome abnormalities detected during cytogenetic investigations for B-cell malignancy offer prognostic information that can have wide ranging clinical impacts on patients. These impacts may include monitoring frequency, treatment type, and disease staging level. The use of the synthetic oligonucleotide DSP30 combined with interleukin 2 (IL2) has been described as an effective mitotic stimulant in B-cell disorders, not only in chronic lymphocytic leukemia (CLL) but also in a range of other B-cell malignancies. Here, we describe the comparison of two B-cell mitogens, lipopolysaccharide (LPS), and DSP30 combined with IL2 as mitogens in a range of common B-cell disorders excluding CLL. The results showed that DSP30/IL2 was an effective mitogen in mature B-cell disorders, revealing abnormal cytogenetic results in a range of B-cell malignancies. The abnormality rate increased when compared to the use of LPS to 64% (DSP30/IL2) from 14% (LPS). In a number of cases the disease burden was proportionally very low, less than 10% of white cells. In 37% of these cases, the DSP30 culture revealed abnormal results. Importantly, we also obtained abnormal conventional cytogenetics results in 3 bone marrow cases in which immunophenotyping showed an absence of an abnormal B-cell clone. In these cases, the cytogenetics results correlated with the provisional diagnosis and altered their staging level. The use of DSP30 and IL2 is recommended for use in many B-cell malignancies as an effective mitogen and their use has been shown to enable successful culture of the malignant clone, even at very low levels of disease. © 2018 Wiley Periodicals, Inc.

  13. Enteric bacterial metabolites propionic and butyric acid modulate gene expression, including CREB-dependent catecholaminergic neurotransmission, in PC12 cells--possible relevance to autism spectrum disorders.

    Full Text Available Alterations in gut microbiome composition have an emerging role in health and disease including brain function and behavior. Short chain fatty acids (SCFA like propionic (PPA, and butyric acid (BA, which are present in diet and are fermentation products of many gastrointestinal bacteria, are showing increasing importance in host health, but also may be environmental contributors in neurodevelopmental disorders including autism spectrum disorders (ASD. Further to this we have shown SCFA administration to rodents over a variety of routes (intracerebroventricular, subcutaneous, intraperitoneal or developmental time periods can elicit behavioral, electrophysiological, neuropathological and biochemical effects consistent with findings in ASD patients. SCFA are capable of altering host gene expression, partly due to their histone deacetylase inhibitor activity. We have previously shown BA can regulate tyrosine hydroxylase (TH mRNA levels in a PC12 cell model. Since monoamine concentration is known to be elevated in the brain and blood of ASD patients and in many ASD animal models, we hypothesized that SCFA may directly influence brain monoaminergic pathways. When PC12 cells were transiently transfected with plasmids having a luciferase reporter gene under the control of the TH promoter, PPA was found to induce reporter gene activity over a wide concentration range. CREB transcription factor(s was necessary for the transcriptional activation of TH gene by PPA. At lower concentrations PPA also caused accumulation of TH mRNA and protein, indicative of increased cell capacity to produce catecholamines. PPA and BA induced broad alterations in gene expression including neurotransmitter systems, neuronal cell adhesion molecules, inflammation, oxidative stress, lipid metabolism and mitochondrial function, all of which have been implicated in ASD. In conclusion, our data are consistent with a molecular mechanism through which gut related environmental signals

    Hyperkinetic movement disorders (HMDs) can be assessed using impairment-based scales or functional classifications. The Burke-Fahn-Marsden Dystonia Rating Scale-movement (BFM-M) evaluates dystonia impairment, but may not reflect functional ability. The Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and Communication Function Classification System (CFCS) are widely used in the literature on cerebral palsy to classify functional ability, but not in childhood movement disorders. We explore the concordance of these three functional scales in a large sample of paediatric HMDs and the impact of dystonia severity on these scales. Children with HMDs (n=161; median age 10y 3mo, range 2y 6mo-21y) were assessed using the BFM-M, GMFCS, MACS, and CFCS from 2007 to 2013. This cross-sectional study contrasts the information provided by these scales. All four scales were strongly associated (all Spearman's rank correlation coefficient rs >0.72, pdisorders including cerebral palsy can be effectively evaluated using these scales. © 2015 Mac Keith Press.

    A 47-year-old man with Epstein-Barr virus (EBV)-positive T/NK- cell lymphoproliferative disease (EBV-T/NK-LPD) developed acute-onset weakness. A nerve conduction study showed a conduction block in both the proximal and most distal segments. Although the patient's neuropathy transiently responded to intravenous immunoglobulin, it was progressive for at least 25 days until the start of prednisolone (PSL) administration, after which it remarkably improved. The neuropathy further improved after allogeneic bone marrow transplantation (BMT). The present patient's clinical course is not consistent with that of typical Guillain-Barré syndrome. This case suggests that EBV-T/NK-LPD can cause progressive immune-mediated neuropathy as a result of chronic EBV antigen presentation and can be treated with PSL and BMT.

    Systemic Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disease (EBV + T-LPD) occurs mainly in Asia and South America and is extremely rare in adults. The disease is characterized by a clonal proliferation of EBV-infected T cells with a cytotoxic immunophenotype and is associated with a poor clinical outcome and can be life-threatening. The majority of the patients have evidence of systemic disease, often with lymph node, liver and spleen involvement. The present study describes a case of adult systemic EBV + T-LPD with high fever, systemic lymphadenopathy, hepatosplenomegaly, nose-pharynx neoplasm, pancytopenia, EB virus infection and proliferative bone marrow, with the aim of improving the understanding of the condition.

    Abstract Objective The purpose of this article was to systematically review the literature on stimulant and atomoxetine combination therapy, in particular: 1) Characteristics of patients with attention-deficit/hyperactivity disorder (ADHD) given combination therapy, 2) treatment strategies used, 3) efficacy and effectiveness, and 4) safety and tolerability. Methods Literature databases (MEDLINE®, EMBASE, Cochrane Central Register of Controlled Trials, Science Citation Index Expanded, and SciVerse Scopus) were systematically searched using prespecified criteria. Publications describing stimulant and atomoxetine combination therapy in patients with ADHD or healthy volunteers were selected for review. Exclusion criteria were comorbid psychosis, bipolar disorder, epilepsy, or other psychiatric/neurologic diseases that could confound ADHD symptom assessment, or other concomitant medication(s) to treat ADHD symptoms. Results Of the 16 publications included for review, 14 reported findings from 3 prospective studies (4 publications), 7 retrospective studies, and 3 narrative reviews/medication algorithms of patients with ADHD. The other two publications reported findings from two prospective studies of healthy volunteers. The main reason for prescribing combination therapy was inadequate response to previous treatment. In the studies of patients with ADHD, if reported, 1) most patients were children/adolescents and male, and had a combined ADHD subtype; 2) methylphenidate was most often used in combination with atomoxetine for treatment augmentation or switch; 3) ADHD symptom control was improved in some, but not all, patients; and 4) there were no serious adverse events. Conclusions Published evidence of the off-label use of stimulant and atomoxetine combination therapy is limited because of the small number of publications, heterogeneous study designs (there was only one prospective, randomized controlled trial), small sample sizes, and geographic bias.

    The therapeutic effects of venlafaxine extended release have been investigated by two prospective observational studies including 8506 patients in the outpatient setting of office based general practitioners and specialists. The efficacy has been documented by the Clinical Global Impression (CGI) scale and by the Hamilton depression (HAMD-21) scale. The tolerability has been assessed by the documentation of adverse events. About (2/3) of the patients were treated because of depression and about (1/3) mainly because of anxiety disorder. The patients of specialists did receive higher dosages and were more severely affected. The response rate on the CGI scale was 87.4 for the patients of general practitioners and 74.2 % for the patients of specialists. The results of the HAMD-21 scale, which has been used by specialists, showed a response rate of 71.8 and a remission rate of 56.3 %. These positive effects could be demonstrated even for the more severely and chronically affected patients. The incidence of adverse events was low in both studies and comparable to the tolerability profile of randomized studies. Importantly, the good tolerability profile was similar even for patients with concomitant cardiovascular disease. In conclusion, these results confirm the efficacy and good tolerability of venlafaxine extended release in the outpatient setting in Germany. Georg Thieme Verlag KG Stuttgart, New York.

    Systemic Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disease of childhood is a rare disease and has a very fulminant clinical course with high mortality. A 21-month-old female patient was referred to our hospital with a 1 week history of fever and was subsequently diagnosed with systemic Epstein-Barr virus-positive T-cell lymphoproliferative disease of childhood. After starting treatment with dexamethasone, she showed early defervescence and improvement of laboratory parameters, and has remained disease-free after stopping steroid treatment, although longer follow-up is necessary. Our report underscores the possibility that this disease entity may be heterogenous in terms of prognosis.

    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

    To explore the lymphocytic clonal expansion in adult patients with Epstein-Barr virus-associated lymphoproliferative diseases (EBV+LPD), and to investigate the experimental methods for EBV+LPD cells so as to provide a more objective measure for the diagnosis, classification and prognosis in the early stage of this disease. Peripheral blood samples from 5 patients with EBV+LPD, 4 patients with adult infectious mononucleosis(IM) as negative control and 3 patients with acute NK-cell leukemia(ANKL) as positive control were collected. Prior to immunochemotherapy, viral loads and clonality were analysed by flow cytometry (FCM), T cell receptor gene rearrangement (TCR) was detected by real-time polymerase chain reaction (RT-PCR), and diversity of EB virus terminal repeat (EBV-TR) was detected by Southern blot. FCM showed only 1 case with clonal TCRVβ in 5 patients with EBV+LPD, TCR clonal expansion could be detected both in patients with IM(4 of 4) and 4 patients with EBV+LPD(4 of 5), Out of patients with EBV+LPD, 1 patient displayed a monoclonal band and 2 patients showed oligoclonal bands when detecting EBV-TR by southen blot. Detecting the diversity of EBV-TR by Southern blot may be the most objective way to reflex clonal transformation of EBV+LPD, which is of great benefit to the diagnosis, classification and prognosis in the early stage of this disease.

    EBV infection causes mononucleosis and is associated with specific subsets of B cell lymphomas. Immunosuppressed patients such as organ transplant recipients are particularly susceptible to EBV-induced lymphoproliferative disease (LPD), which can be fatal. Leflunomide (a drug used to treat rheumatoid arthritis) and its active metabolite teriflunomide (used to treat multiple sclerosis) inhibit de novo pyrimidine synthesis by targeting the cellular dihydroorotate dehydrogenase, thereby decreasing T cell proliferation. Leflunomide also inhibits the replication of cytomegalovirus and BK virus via both "on target" and "off target" mechanisms and is increasingly used to treat these viruses in organ transplant recipients. However, whether leflunomide/teriflunomide block EBV replication or inhibit EBV-mediated B cell transformation is currently unknown. We show that teriflunomide inhibits cellular proliferation, and promotes apoptosis, in EBV-transformed B cells in vitro at a clinically relevant dose. In addition, teriflunomide prevents the development of EBV-induced lymphomas in both a humanized mouse model and a xenograft model. Furthermore, teriflunomide inhibits lytic EBV infection in vitro both by preventing the initial steps of lytic viral reactivation, and by blocking lytic viral DNA replication. Leflunomide/teriflunomide might therefore be clinically useful for preventing EBV-induced LPD in patients who have high EBV loads yet require continued immunosuppression.

    Colloidal silver (AgC) is currently used by humans and it can be internalized through inhalation, injection, ingestion, and dermal contact. However, there is limited information about immunological activity; more investigations using colloidal silver are needed. In the present study, the effects of AgC (17.5 ng/m L) on immunological parameters (proliferation and immuno phenotyping) using human peripheral blood mononuclear cells (PBMC) and macrophages (phagocytosis) and cytotoxicity on leukemia and lymphoma cancer cell lines (1.75 to 17.5 ng/m L) were investigated. AgC was observed to significantly ρ) decrease interleukin-2 (I L-2) production and proliferation induced by phytohemagglutinin or concanavalin A in PBMC without affecting its cell viability but with cytotoxic effect on cancer cells. IL-2, IL-4, IL-6, IL-10, INF-γ, and IL_-17 A cytokines production and CD3"+, CD3"-CD19"+, CD3"+CD4"+, CD3"+CD8"+, and CD16"+CD56"+ PBMC phenotypes were not affected by AgC. The present study demonstrates that colloidal silver is harmless and nontoxic to the immune system cells and its ability to interfere with the immune response by decreasing cell proliferation when stimulated with mitogens demonstrated the anti lymphoproliferative potential of AgC

    Autoimmune lymphoproliferative syndrome (ALPS) is characterized by childhood onset of lymphadenopathy, hepatosplenomegaly, autoimmune cytopenias, elevated numbers of double-negative T (DNT) cells, and increased risk of lymphoma. Most cases of ALPS are associated with germline mutations of the FAS gene (type Ia), whereas some cases have been noted to have a somatic mutation of FAS primarily in their DNT cells. We sought to determine the proportion of patients with somatic FAS mutations among a group of our ALPS patients with no detectable germline mutation and to further characterize them. We found more than one-third (12 of 31) of the patients tested had somatic FAS mutations, primarily involving the intracellular domain of FAS resulting in loss of normal FAS signaling. Similar to ALPS type Ia patients, the somatic ALPS patients had increased DNT cell numbers and elevated levels of serum vitamin B(12), interleukin-10, and sFAS-L. These data support testing for somatic FAS mutations in DNT cells from ALPS patients with no detectable germline mutation and a similar clinical and laboratory phenotype to that of ALPS type Ia. These findings also highlight the potential role for somatic mutations in the pathogenesis of nonmalignant and/or autoimmune hematologic conditions in adults and children.

    2014-01-01

    Full Text Available Introduction: It is well known that the incidence of malignancy is significantly higher in transplanted patients than in general population. The incidence of lymphoproliferative disease post-transplantation (PTLD is approximately of 1% to 2% in kidney transplantation recipients. Objective: The main objective of this study was to evaluate the PTLD incidence when monitoring kidney transplanted patients between the years 2005 and 2010. Methods: Kidney transplanted patients’ data was retrospectively taken between the years 2005 to 2010 in order to determine the number of PTLD cases according to the inductor scheme used. Results: 425 patients were transplanted between 2005 and 2010. They received alemtuzumab 76.2%, daclizumab 10.7%, basiliximab 3.6% and thymoglobulin 2.4%. The 7% did not receive antibody induction. During this period 2 cases of PTLD ocurred: One with multiple myeloma and the other with lymphoma. One of them had been treated with alemtuzumab and the other with thymoglobulin. Conclusions: The PTLD incidence in our group, where alemtuzumab was used predominantly as inductor, was very low; this might suggest that alemtuzumab is a medication that does not increase the risk of this kind of neoplasia.

    The role of antiviral prophylaxis for the prevention of posttransplant lymphoproliferative disease (PTLD) remains controversial for solid organ transplantation (SOT) recipients who are seronegative for Epstein-Barr virus (EBV) but who received organs from seropositive donors. We performed a systematic review and meta-analysis to address this issue. Two independent assessors extracted data from studies after determining patient eligibility and completing quality assessments. Overall, 31 studies were identified and included in the quantitative synthesis. Nine studies were included in the direct comparisons (total 2366 participants), and 22 were included in the indirect analysis. There was no significant difference in the rate of EBV-associated PTLD in SOT recipients among those who received prophylaxis (acyclovir, valacyclovir, ganciclovir, valganciclovir) compared with those who did not receive prophylaxis (nine studies; risk ratio 0.95, 95% confidence interval 0.58-1.54). No significant differences were noted across all types of organ transplants, age groups, or antiviral use as prophylaxis or preemptive therapy. There was no significant heterogeneity in the effect of antiviral prophylaxis on the incidence of PTLD. In conclusion, the use of antiviral prophylaxis in high-risk EBV-naive patients has no effect on the incidence of PTLD in SOT recipients. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

  9. GLUT1 deficiency syndrome as a cause of encephalopathy that includes cognitive disability, treatment-resistant infantile epilepsy and a complex movement disorder.

    Graham, John M

    2012-05-01

    Glucose transporter-1 (GLUT1) deficiency syndrome is caused by heterozygous mutations in the SLC2A1 gene, resulting in impaired glucose transport into the brain. It is characterized by a low glucose concentration in the cerebrospinal fluid (hypoglycorrhachia) in the absence of hypoglycemia, in combination with low to normal lactate in the cerebrospinal fluid (CSF). It often results in treatment-resistant infantile epilepsy with progressive developmental disabilities and a complex movement disorder. Recognizing GLUT1 deficiency syndrome is important, since initiation of a ketogenic diet can reduce the frequency of seizures and the severity of the movement disorder. There can be a considerable delay in diagnosing GLUT1 deficiency syndrome, and this point is illustrated by the natural history of this disorder in a 21-year-old woman with severe, progressive neurological disabilities. Her encephalopathy consisted of treatment-resistant seizures, a complex movement disorder, progressive intellectual disability, and deceleration of her head growth after late infancy. Focused evaluation at age 21 revealed GLUT1 deficiency caused by a novel heterozygous missence mutation in exon 7 (c.938C > A; p.Ser313Try) in SLC2A1 as the cause for her disabilities.

    Epstein-Barr virus (EBV) is a major cause of immunosuppression-related B-cell lymphomas and Hodgkin lymphoma (HL). In these malignancies, EBV latent membrane protein 1 (LMP1) and LMP2A provide infected B cells with surrogate CD40 and B-cell receptor growth and survival signals. To gain insights into their synergistic in vivo roles in germinal center (GC) B cells, from which most EBV-driven lymphomas arise, we generated a mouse model with conditional GC B-cell LMP1 and LMP2A coexpression. LMP1 and LMP2A had limited effects in immunocompetent mice. However, upon T- and NK-cell depletion, LMP1/2A caused massive plasmablast outgrowth, organ damage, and death. RNA-sequencing analyses identified EBV oncoprotein effects on GC B-cell target genes, including up-regulation of multiple proinflammatory chemokines and master regulators of plasma cell differentiation. LMP1/2A coexpression also up-regulated key HL markers, including CD30 and mixed hematopoietic lineage markers. Collectively, our results highlight synergistic EBV membrane oncoprotein effects on GC B cells and provide a model for studies of their roles in immunosuppression-related lymphoproliferative diseases.

    Animal models of human EBV-associated diseases are essential to elucidate the pathogenesis of EBV-associated diseases. Here we review those previous models using EBV or EBV-like herpesviruses and describe the details on our two newly-developed rabbit models of lymphoproliferative diseases (LPD) induced by simian EBV-like viruses. The first is Cynomolgus-EBV-induced T-cell lymphomas in rabbits inoculated intravenously (77-90%) and orally (82-89%) during 2-5 months. EBV-DNA was detected in peripheral blood by PCR from 2 days after oral inoculation, while anti-EBV-VCA IgG was raised 3 weeks later. Rabbit lymphomas and their cell lines contained EBV-DNA and expressed EBV-encoded RNA-1 (EBER-1). Rabbit lymphoma cell lines, most of which have specific chromosomal abnormality, showed tumorigenicity in nude mice. The second is the first animal model for EBV-infected T-cell LPD with virus-associated hemophagocytic syndrome (VAHS), using rabbits infected with an EBV-like herpesvirus, Herpesvirus papio (HVP). Rabbits inoculated intravenously with HVP-producing cells showed increased anti-EBV-VCA-IgG titers, and most (85%) subsequently died of fatal LPD and VAHS, with bleeding and hepatosplenomegaly, during 22-105 days. Peroral spray of cell-free HVP induced viral infection with seroconversion in 3 out of 5 rabbits, with 2 of the 3 infected rabbits dying of LPD with VAHS. Atypical T lymphocytes containing HVP-DNA and expressing EBER-1 were observed in many organs. Hemophagocytic histiocytosis was observed in the lymph nodes, spleen, bone marrow, and thymus. These rabbit models are also useful and inexpensive alternative experimental model systems for studying the biology and pathogenesis of EBV, and prophylactic and therapeutic regimens.

    Post transplant lymphoproliferative disease (PTLD) is a severe complication after solid organ or bone marrow transplantation. In pediatric transplant recipients PTLD is the most common malignancy. The aim of this study was to evaluate a possible role for positron emission tomography with [{sup 18}F]-2-fluoro-2-desoxy-glucose (FDG) in the initial staging and in therapy monitoring of pediatric patients suffering from biopsy-proven CD20-positive PTLD after solid organ transplantation. Seven pediatric patients were included. All available imaging studies - CT (n = 15), MRI (n = 16) and PET/PETCT (n = 16) - were reviewed on a lesion by lesion base. The performance of FDG-PET in the initial staging and during therapy with a chimeric anti-CD20 antibody was compared to conventional cross sectional imaging and correlated with the clinical outcome. FDG-PET identified all sites of disease as shown by CT/MRI and helped to clarify the significance of equivocal findings. The initial stage of disease was correctly identified by FDG-PET alone when compared to CT/MRI. During therapy, FDG-PET was superior to conventional cross-sectional imaging in the early evaluation of response.

  14. Utility of simultaneous assessment of bone marrow aspirates and trephine biopsy sections in various haematological disorders

    Conclusion: Bone marrow aspiration alone is sufficient for the diagnosis of megaloblastic anemia and most of the hematological malignancies. Bone marrow biopsy is more appropriate for detection of disorders with focal marrow involvement such as lymphoproliferative disorders, metastatic cancer, focal blast crisis in CML, granulomatous lesions, and hypoplastic marrow. However, it is strongly recommended that both should be reviewed simultaneously to ensure maximum diagnostic accuracy.

    The kinetics of 5-HT uptake by platelets was studied in cases of infantile autism and developmental language disorder (DLD) and normal subjects. Two patients of the autism group were twins, and the seven patients of the DLD group were members of four pairs of twins. The Vmax values (means +/- SD) for autism and DLD were 6.46 +/- .90 pmol 5-HT/10(7) cells/min and 4.85 +/- 1.50 pmol 5-HT/10(7) cells/min, respectively. These values were both significantly higher than that of 2.25 +/- .97 pmole 5-HT/10(7) cells/min for normal children. The Km values of the three groups were not significantly different. Data on the five pairs of twins examined suggested that the elevated Vmax of 5-HT uptake by platelets was determined genetically

  17. Epstein-Barr Virus-Negative Post-Transplant Lymphoproliferative Diseases: Three Distinct Cases from a Single Center

    2014-03-01

    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.

  18. Lack of correlation between immunologic markers and cell surface ultrastructure in the leukemic phase of lymphoproliferative diseases

    In a prospective study of malignant cells from 13 patients with the leukemic phase of lymphoproliferative diseases, we wished to determine whether any correlation between the immunologic markers and the cell surface ultrastructure. Five patients had chronic lymphocytic leukemia, four had malignant lymphomas, poorly differentiated lymphocytic type, two had the Sezary syndrome, and one each had acute prolymphocytic leukemia and acute lymphocytic leukemia. Cell separation and isolation was done at room temperature for all specimens. Immunologic markers tested for were surface immunoglobins, a B-cell property, and E-rosettes, a T-cell property. Three patients had T-cell diseases, 6 had B-cell diseases, and 4 were classified as ''null.'' All but one patient had moderate to large numbers of microvilli on their malignant cells. The single exception had a typical B-cell form of chronic lymphocytic leukemia. There appears to be no correlation between immunologic markers and cell surface ultrastructure; therefore, SEM appears not to be valuable in the diagnosis or classification of immunologic sub-types of certain lymphoproliferative diseases.

    There is little research on short-term treatments for borderline personality disorder (BPD). While the core changes may occur only in long-term treatments, short-term treatments may enable the study of early generic processes of engagement in therapy and thus inform about effective treatment components. It was shown that a 10-session version of a psychiatric treatment was effective in reducing borderline symptoms at the end of this treatment [Kramer, U., Kolly, S., Berthoud, L., Keller, S., Preisig, M., Caspar, F., … Despland, J.-N. (2014). Effects of motive-oriented therapeutic relationship in a ten-session general psychiatric treatment for borderline personality disorder: A randomized controlled trial. Psychotherapy and Psychosomatics, 83, 176-186.]. Also, it was demonstrated in a randomized design that adding the motive-oriented therapeutic relationship (MOTR), following an individualized case formulation based on Plan Analysis, further increased general outcome after session 10 and had a positive effect on the early changes in self-esteem and alliance. The present study focuses on the follow-up period after this initial treatment, examining treatment density and outcomes after 6 months and service utilization after 12 months. Outcome was measured using the OQ-45. Results on a sub-sample of N = 40 patients with available OQ-45 data at follow-up (n = 21 for MOTR-treatment, n = 19 for comparison treatment) showed maintenance of gains over the follow-up period, which did not differ between both conditions. It appeared for this sample that MOTR treatments, while using the same number of sessions, lasted more weeks (i.e., lower treatment density, defined as the number of sessions per week), when compared to the treatments without MOTR. Density marginally predicted symptom reduction at follow-up. Patients in MOTR treatments had a greater likelihood of entering structured psychotherapy after the initial sessions than patients in the comparison

    Psychological distress and deficits in executive functioning are likely to be important barriers to effective weight loss maintenance. The purpose of this paper is twofold. First, in the light of recent evidence in the fields of neuropsychology and obesity, particularly on the deficits in the executive function in overweight and obese individuals, a conceptual and theoretical framework of obesity maintenance is introduced by way of a clinical obesity maintenance model (COMM). It is argued that psychological variables, that of habitual cluster Behaviors, emotional dysregulation, mood, and health literacy, interact with executive functioning and impact on the overeating/binge eating behaviors of obese individuals. Second, cognizant of this model, it is argued that the focus of obesity management should be extended to include a broader range of maintaining mechanisms, including but not limited to cognitive deficits. Finally, a discussion on potential future directions in research and practice using the COMM is provided.

    Diagnostic problems with the criteria of attention deficit hyperactivity disorder (ADHD) in the Diagnostic Statistical Manual, 4th edn, have been identified. The aim of this study was to clarify whether the minor neurological signs test (MNT) the authors had previously reported was a predictor for the criteria of ADHD or hyperactivity disorder (HD) in perinatal risk children at 4-6 years of age and what kind of risk factors related to MNT. A total of 136 children discharged from neonatal intensive care units were examined at the age of 4-6 years by a developmental neuropediatrician using both MNT and diagnostic criteria of DSM-IV ADHD/ICD-10 (International Classification of Diseases, 10th edn) HD. SPSS base and professional were used for statistical analysis. On comparison of diagnostic criteria between ADHD (11.0%) and HD (27.5%), the incidence in the same subjects showed significant difference. MNT scores showed significant correlation with criteria of ADHD (P Apgar 5 in the NLBW group and toxemia of pregnancy and small for gestational age (SGA) in VLBW group were highly correlated with behavioral outcome. Minor neurological signs test score was a significant predictor for criteria of ADHD and HD. High incidences of positive MNT were suspected in not only VLBW children but also NLBW children and Apgar 5 in NLBW children and toxemia of pregnancy and SGA in VLBW children influenced behavioral outcome.

    Online psychotherapy has been successfully used as supportive treatment in many chronic illnesses. However, there is a lack of evidence on its role in the management of gastrointestinal (GI) diseases. To examine whether online psychological interventions improve mental and physical outcomes in gastrointestinal diseases. We searched CINAHL Plus, MEDLINE, EMBASE, Health Management Information Consortium, PsycINFO, British Nursing Index, Cochrane Library, a specialised register of the IBD/FBD Cochrane Group, MEDLINE (PubMed) WHO International Clinical Trial Registry, ClinicalTrials.gov, and reference lists of all papers included in the review. The Cochrane Risk of Bias Tool was used to assess internal validity. Where possible, data were pooled using random-effects meta-analysis. We identified 11 publications (encompassing nine studies) meeting inclusion criteria. One study had a high risk of selection bias (allocation concealment), all studies had a high risk of performance and detection bias. Eight studies were included in the meta-analyses (6 on irritable bowel syndrome [IBS] and two on inflammatory bowel disease [IBD]). Online cognitive behavioural therapy (CBT) was shown to significantly improve gastrointestinal symptom-specific anxiety (MD: -8.51, 95% CI -12.99 to -4.04, P = 0.0002) and lessen symptom-induced disability (MD: -2.78, 95% CI -5.43 to -0.12, P = 0.04) in IBS post intervention. There was no significant effect of online CBT on any other outcomes in IBS. No significant effect of online psychotherapy was demonstrated in IBD. There is insufficient evidence to demonstrate the effectiveness of online CBT to manage mental and physical outcomes in gastrointestinal diseases. © 2018 John Wiley & Sons Ltd.

    Epstein-Barr virus-positive T/NK-cell lymphoproliferative diseases (EBV-T/NK-LPDs) include several overlapping EBV-related conditions with variably aggressive courses. For prognostic categorization, we retrospectively analyzed 42 EBV-T/NK-LPD cases. Male (79% [33/42]), young (≤40 years; 83% [35/42]) patients and T-cell lineage (81% [34/42]; CD8/CD4 = 1.8) were predominant. Clinicopathologically, three systemic and one cutaneous category were developed: hemophagocytic lymphohistiocytosis (HLH; 26% [11/42]), chronic active EBV infection (CAEBV; 31% [13/42]), systemic unclassifiable disease (24% [10/42]), and hydroa vacciniforme/hydroa vacciniforme-like lymphoma (HV/HVL; 19% [8/42]). Prognostically, cutaneous disease (HV/HVL) was better than systemic disease (p = 0.014; median, 285 vs. 10 months). In systemic diseases, HLH was worst (p = 0.002; 3[HLH] vs. 4[unclassifiable] vs. not reached [CAEBV]). Univariate survival analysis (n = 42) revealed cytopenia (≥one lineage; p 40 years; p = 0.001), T-cell lineage (p = 0.041), hemophagocytic histiocytes (p = 0.031), elevated lactate dehydrogenase (p = 0.020), and liver dysfunction (p = 0.023) predicted shorter survival. In multivariate analysis, T-cell lineage (p = 0.025 [HR =11.3]) and cytopenia (p = 0.028 [HR =5.4]) were independent prognostic factors. Therefore, EBV-T/NK-LPD could be classified into four prognostic categories.

    Epstein-Barr virus (EBV)-associated T-cell lymphoproliferative disease (LPD) is not uncommon in China, but gastrointestinal involvement is very rare. We report on an immunocompetent patient with EBV-associated T-cell LPD of the colon. The 26-year-old man was initially misdiagnosed with ulcerative colitis (UC). A colon biopsy revealed the presence of small to medium-sized lymphoid cells infiltrating the intestinal wall. The neoplastic cells expressed CD3, CD5, and granzyme B, not CD56. EBV-encoded small ribonucleic acid was detected in the tumor cells of the colon as well as the lymph node, and the T-cell receptor gene rearrangement result displayed δ gene monoclonal rearrangement. The patient died 2 moths after the diagnosis. The clinical course of EBV-associated T-cell LPD is aggressive and the prognosis is poor, the wrong diagnosis may delay treatment. Therefore, we should be very careful to prevent misdiagnosis. When patients have multiple intestinal ulcers that are not typical of UC and the clinical course is unusual, although morphology looks like inflammatory change, pathologist should consider the possibility of EBV-associated LPD. The treatment strategy and prognosis of these two diseases are different.

    The Epstein-Barr virus load in the peripheral blood at the time of diagnosis of post-transplant lymphoproliferative disease (PTLD) is elevated 1000- to 10,000-fold compared to the level detected in normal latency. With the use of quantitative polymerase chain reaction (PCR), changes in the viral load over time can be measured with a two- to fourfold accuracy. This has allowed early detection of first-time infections and reactivations that may lead to PTLD and has provided an opportunity to intervene before symptomatic disease has occurred. Viral load monitoring has also been used to follow patients with PTLD and, along with other parameters, provided an assessment of the effectiveness of therapeutic protocols. Viral load monitoring has led to the discovery that at least two-thirds of transplant recipients become persistent viral load carriers. While the persistent load appears to be largely carried in latently infected memory B cells, more work is needed to clearly define this type of persistent infection and determine the risks associated with it. New diagnostic tests need to be developed to distinguish the persistent latent viral loads from viral loads that are likely to become symptomatic PTLD.

    AIMS To determine the frequency of the FAS-ligand gene (FASLG) variant associated with feline autoimmune lymphoproliferative syndrome (FALPS) and the proportion of carriers of the variant in three British shorthair (BSH) breeding catteries in New Zealand. METHODS Buccal swabs were collected from all cats in two BSH breeding catteries from the South Island and one from the North Island of New Zealand. DNA was extracted and was tested for the presence of the FASLG variant using PCR. Cats with the FASLG variant were identified and the frequency of the FASLG variant allele calculated. Pedigree analysis was performed and inbreeding coefficients were calculated for cats with the FASLG variant. RESULTS Of 32 BSH cats successfully tested for the presence of the FASLG variant, one kitten (3%) was homozygous (FALPS-affected), and seven (22%) cats were heterozygous (carriers) for the FASLG variant allele, and 24 (75%) cats were homozygous for the wild type allele. The overall frequency of the FASLG variant allele in these 32 cats was 0.14. Cats carrying the FASLG variant were from all three breeding catteries sampled, including two catteries that had not previously reported cases of FALPS. Pedigree analysis revealed common ancestry of FALPS-affected and carrier cats within six generations, as well as frequent inbreeding, with inbreeding coefficients >0.12 for five cats with the FASLG variant. CONCLUSIONS AND CLINICAL RELEVANCE There was a high frequency of the FASLG variant allele (0.14) in this small sample of BSH cats, with 22% of healthy cats identified as carriers of the FASLG variant. For an inherited disease, lethal at a young age, in a small population in which inbreeding is common, these results are significant. To prevent future cases of disease and stop further spread of the FASLG variant allele within the BSH population in New Zealand, it is recommended that all BSH and BSH-cross cats be tested for the presence of the FASLG variant before mating. Cats identified as

    Deletion or duplication of one copy of the human 16p11.2 interval is tightly associated with impaired brain function, including autism spectrum disorders (ASDs, intellectual disability disorder (IDD and other phenotypes, indicating the importance of gene dosage in this copy number variant region (CNV. The core of this CNV includes 25 genes; however, the number of genes that contribute to these phenotypes is not known. Furthermore, genes whose functional levels change with deletion or duplication (termed ‘dosage sensors’, which can associate the CNV with pathologies, have not been identified in this region. Using the zebrafish as a tool, a set of 16p11.2 homologs was identified, primarily on chromosomes 3 and 12. Use of 11 phenotypic assays, spanning the first 5 days of development, demonstrated that this set of genes is highly active, such that 21 out of the 22 homologs tested showed loss-of-function phenotypes. Most genes in this region were required for nervous system development – impacting brain morphology, eye development, axonal density or organization, and motor response. In general, human genes were able to substitute for the fish homolog, demonstrating orthology and suggesting conserved molecular pathways. In a screen for 16p11.2 genes whose function is sensitive to hemizygosity, the aldolase a (aldoaa and kinesin family member 22 (kif22 genes were identified as giving clear phenotypes when RNA levels were reduced by ∼50%, suggesting that these genes are deletion dosage sensors. This study leads to two major findings. The first is that the 16p11.2 region comprises a highly active set of genes, which could present a large genetic target and might explain why multiple brain function, and other, phenotypes are associated with this interval. The second major finding is that there are (at least two genes with deletion dosage sensor properties among the 16p11.2 set, and these could link this CNV to brain disorders such as ASD and IDD.

    The Pervasive Developmental Disorders are a group of neurodevelopmental disorders that include Autistic Disorder, Asperger’s Disorder, Pervasive Developmental Disorder - Not Otherwise Specified (PDD-NOS), Childhood Disintegrative Disorder (CDD), and Rett’s Disorder. All feature childhood onset with a constellation of symptoms spanning social interaction and communication and including atypical behavior patterns. The first three disorders (Autistic Disorder, Asperger’s Disorder, and PDD-NOS) are currently referred to as Autism Spectrum Disorders, reflecting divergent phenotypic and etiologic characteristics compared to Rett’s Disorder and CDD. This chapter reviews relevant research and clinical information relevant to appropriate medical diagnosis and treatment. PMID:22608634

    We report a case of the extremely rare condition Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disease (LPD) which occurred after umbilical cord blood transplantation. A 25-year-old Japanese man underwent cord blood transplantation from a male human leukocyte antigen 4/6-matched donor due to acute myeloid leukemia with trisomy 8. Bone marrow examination on day 30 showed chimerism with at least 90% donor cells and complete hematological response. Chronic symptoms of graft-versus-host disease appeared only on the skin and were successfully treated with cyclosporine alone. Three years later, however, the patient experienced repeated cold-like symptoms and was hospitalized with liver dysfunction. A high fever developed and was followed by significant edema of the right side of the face. The EBV DNA copy number in whole peripheral blood was 2×10(4)/mL. Liver biopsy showed invasion of EBV-infected CD8-positive T cells. Southern blotting analysis of the whole peripheral blood showed that the T-cell receptor Cβ1 rearrangement was positive. On the basis of these results, EBV-positive T-cell LPD was diagnosed and treated with prednisolone, cyclosporine, and etoposide, followed by cyclophosphamide, doxorubicin, vincristine, and prednisone. However, the patient died of cardiac function failure, pneumonia, and pulmonary hemorrhage, all of unidentified cause. Most cases of EBV-related LPD after hematopoietic stem cell transplantation consist of EBV-positive B-cell LPD, and, to our knowledge, de novo EBV-positive T-cell LPD subsequent to transplantation has not been previously reported.

    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

    The human immunoglobulin heavy-chain (IGH) locus at chromosome 14q32 is frequently involved in different translocations of non-Hodgkin lymphoma (NHL), and the detection of any breakage involving the IGH locus should identify a B-cell NHL. The split-signal IGH fluorescence in situ hybridization-chromogenic in situ hybridization (FISH-CISH) DNA probe is a mixture of 2 fluorochrome-labeled DNAs: a green one that binds the telomeric segment and a red one that binds the centromeric segment, both on the IGH breakpoint. In the current study, the authors tested the capability of the IGH FISH-CISH DNA probe to detect IGH translocations and diagnose B-cell lymphoproliferative processes on cytological samples. Fifty cytological specimens from cases of lymphoproliferative processes were tested using the split-signal IGH FISH-CISH DNA probe and the results were compared with light-chain assessment by flow cytometry (FC), IGH status was tested by polymerase chain reaction (PCR), and clinicohistological data. The signal score produced comparable results on FISH and CISH analysis and detected 29 positive, 15 negative, and 6 inadequate cases; there were 29 true-positive cases (66%), 9 true-negative cases (20%), 6 false-negative cases (14%), and no false-positive cases (0%). Comparing the sensitivity of the IGH FISH-CISH DNA split probe with FC and PCR, the highest sensitivity was obtained by FC, followed by FISH-CISH and PCR. The split-signal IGH FISH-CISH DNA probe is effective in detecting any translocation involving the IGH locus. This probe can be used on different samples from different B-cell lymphoproliferative processes, although it is not useful for classifying specific entities.

    of sarcoidosis with questionable efficacy. The high toxicity profile of these agents, including an increased risk of lymphoproliferative disorders and carcinomas, has limited their use to patients with severe disease refractory to other agents. Successful steroid sparing treatment with mycophenolate mofetil was described in an adolescent with renal-limited sarcoidosis complicated by renal failure. Novel treatment strategies for sarcoidosis have been developed including the use of TNF-alpha inhibitors, such as infliximab. The long-term course and prognosis is not well established in childhood sarcoidosis, but it appears to be poorer in early-onset disease.

    The ACCESS-model offers integrated care including assertive community treatment to patients with psychotic disorders. ACCESS proved more effective compared to standard care (ACCESS-I study) and was successfully implemented into clinical routine (ACCESS-II study). In this article, we report the 4-year outcomes of the ACCESS-II study. Between May 2007 and December 2013, 115 patients received continuous ACCESS-care. We hypothesized that the low 2-year disengagement and hospitalization rates and significant improvements in psychopathology, functioning, and quality of life could be sustained over 4 years. Over 4 years, only 10 patients disengaged from ACCESS. Another 23 left for practical reasons and were successfully transferred to other services. Hospitalization rates remained low (13.0% in year 3; 9.1% in year 4). Involuntary admissions decreased from 35% in the 2 years prior to ACCESS to 8% over 4 years in ACCESS. Outpatient contacts remained stably high at 2.0-2.4 per week. We detected significant improvements in psychopathology (effect size d = 0.79), illness severity (d = 1.29), level of functioning (d = 0.77), quality of life (d = 0.47) and stably high client satisfaction (d = 0.02) over 4 years. Most positive effects were observed within the first 2 years with the exception of illness severity, which further improved from year 2 to 4. Within continuous intensive 4-year ACCESS-care, sustained improvements in psychopathology, functioning, quality of life, low service disengagement and re-hospitalization rates, as well as low rates of involuntary treatment, were observed in contrast to other studies, which reported a decline in these parameters once a specific treatment model was stopped. Yet, stronger evidence to prove these results is required. Clinical Trial Registration Number: NCT01888627.

    There is limited clinical evidence on the utility of the monitoring of Epstein-Barr virus (EBV) DNAemia in the pre-emptive management of post-transplant lymphoproliferative disease (PTLD) in solid organ transplant (SOT) recipients. We investigated current preventive measures against EBV-related PTLD through a web-based questionnaire sent to 669 SOT programmes in 35 European countries. This study was performed on behalf of the ESGICH study group from the European Society of Clinical Microbiology and Infectious Diseases. A total of 71 SOT programmes from 15 European countries participated in the study. EBV serostatus of the recipient is routinely obtained in 69/71 centres (97%) and 64 (90%) have access to EBV DNAemia assays. EBV monitoring is routinely used in 85.9% of the programmes and 77.4% reported performing pre-emptive treatment for patients with significant EBV DNAemia levels. Pre-emptive treatment for EBV DNAemia included reduction of immunosuppression in 50.9%, switch to mammalian target of rapamycin inhibitors in 30.9%, and use of rituximab in 14.5% of programmes. Imaging by whole-body 18-fluoro-deoxyglucose positron emission tomography (FDG-PET) is used in 60.9% of centres to rule out PTLD and complemented computer tomography is used in 50%. In 10.9% of centres, FDG-PET is included in the first-line diagnostic workup in patients with high-risk EBV DNAemia. Despite the lack of definitive evidence, EBV load measurements are frequently used in Europe to guide diagnostic workup and pre-emptive reduction of immunosuppression. We need prospective and controlled studies to define the impact of EBV monitoring in reducing the risk of PTLD in SOT recipients.

    Epstein-Barr virus-related lymphoproliferative disease (EBV-LPD) rarely occurs in patients with acute lymphoblastic leukemia (ALL), who have not received hematopoietic transplantation. We describe EBV-LPD manifesting as facial lesions in two children with ALL in remission. One patient was a 16-year-old male with T-cell ALL with an EBV-positive angiocentric polymorphous lip lesion presenting as right-sided facial swelling. The other patient was a 12-year-old male with B-cell ALL with an EBV-positive polymorphous lymphoplasmacytic infiltrate presenting as bilateral dacryoadenitis. Neither patient had known primary immunodeficiencies. Both cases improved with immunosuppressant de-escalation. These cases suggest that immunosuppression induced by maintenance chemotherapy is sufficient to promote EBV-LPD. © 2016 Wiley Periodicals, Inc.

    Eating disorders are characterized by aberrant patterns of eating behavior, including such symptoms as extreme restriction of food intake or binge eating, and severe disturbances in the perception of body shape and weight, as well as a drive for thinness and obsessive fears of becoming fat. Eating disorder is an important cause for physical and psychosocial morbidity in young women. Patients with eating disorders have a deficit in the cognitive process and functional abnormalities in the brain system. Recently, brain-imaging techniques have been used to identify specific brain areas that function abnormally in patients with eating disorders. We have discussed the clinical and cognitive aspects of eating disorders and summarized neuroimaging studies of eating disorders.

    We have studied the efficacy of adaptol in the treatment of 45 patients with somatoform dysfunction of the autonomic nervous system and 30 patients with closed head injury. The condition of patients during the treatment was evaluated with clinical and neuropsychological scales. The serum level of BDNF before and after the treatment has been studied as well. Adaptol has been shown to enhance the production of BDNF, reduce significantly the intensity of anxiety, autonomic disorders and improve intellectual processes. The dose-dependent effect of the drug has been demonstrated. In conclusion, adaptol can be recommended for treatment of diseases that demand stimulation of neuroplasticity in the CNS.

    To examine the risk of late-onset post-transplant lymphoproliferative disorder (PTLD) in the presence of persisting high Epstein-Barr virus (EBV) in EBV naïve pediatric heart transplant (HT) recipients. A retrospective review of the medical records of the 145 pediatric HT recipients who had serial EBV viral load monitoring at our center was performed. We defined EBV naive patients whose EBV serology either IgM or IgG in the blood were negative at the time of HT and excluded passive transmission from mother to child in subjects less than 6 mo of age. PTLD was diagnosed in 8 out of 145 patients (5.5%); 6/91 (6.5%) in those who were EBV seropositive and 2/54 (3.7%) in the EBV naïve group at the time of HT ( P = 0.71). We found 32/145 (22%) patients with persistently high EBV load during continuing follow-up; 20/91 (22%) in EBV seropositive group vs 12/54 (22%) in EBV naïve group ( P = 0.97). There was no significant association between pre-HT serostatus and EBV load after transplant ( P > 0.05). In the EBV seropositive group, PTLD was diagnosed in 15% (3/20) of patients with high EBV vs 4.2% (3/71) of patients with low or undetectable EBV load ( P = 0.14) whereas in EBV naïve patients 8.3% (1/12) of those with high EBV load and 2.3% (1/42) with low or undetectable EBV load ( P = 0.41). There was a highly significant association between occurrence of PTLD in those with high EBV load and duration of follow up (4.3 ± 3.9 years) after HT by Cochran-Armitage test for the entire cohort ( P = 0.005). At least one episode of acute rejection occurred in 72% (23/32) of patients with high EBV vs 36% (41/113) patients with low or undetectable EBV after HT ( P < 0.05). There is an association between persistently high EBV load during post-HT follow up and the occurrence of late-onset PTLD in pediatric HT recipients irrespective of serostatus at the time of transplant. The occurrence of allograft rejection increased in patients with high EBV load presumably due to reduction in

    Little evidence exists on the treatment of traumatised refugees. To estimate treatment effects of flexible cognitive-behavioural therapy (CBT) and antidepressants (sertraline and mianserin) in traumatised refugees. Randomised controlled clinical trial with 2 × 2 factorial design (registered with Clinicaltrials.gov, NCT00917397, EUDRACT no. 2008-006714-15). Participants were refugees with war-related traumatic experiences, post-traumatic stress disorder (PTSD) and without psychotic disorder. Treatment was weekly sessions with a physician and/or psychologist over 6 months. A total of 217 of 280 patients completed treatment (78%). There was no effect on PTSD symptoms, no effect of psychotherapy and no interaction between psychotherapy and medicine. A small but significant effect of treatment with antidepressants was found on depression. In a pragmatic clinical setting, there was no effect of flexible CBT and antidepressants on PTSD, and there was a small-to-moderate effect of antidepressants and psychoeducation on depression in traumatised refugees. © The Royal College of Psychiatrists 2016.

    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.

    Gambling disorders, including pathological gambling and problem gambling, have received increased attention from clinicians and researchers over the past three decades since gambling opportunities have expanded around the world. This Seminar reviews prevalence, causes and associated features, screening and diagnosis, and treatment approaches. Gambling disorders affect 0·2-5·3% of adults worldwide, although measurement and prevalence varies according to the screening instruments and methods used, and availability and accessibility of gambling opportunities. Several distinct treatment approaches have been favourably evaluated, such as cognitive behavioural and brief treatment models and pharmacological interventions. Although promising, family therapy and support from Gamblers Anonymous are less well empirically supported. Gambling disorders are highly comorbid with other mental health and substance use disorders, and a further understanding is needed of both the causes and treatment implications of this disorder.

    2017-07-01

    Full Text Available Anxiety disorders are highly prevalent among children and are associated with serious morbidity. Lifetime prevalence of paediatric anxiety disorders is about fifteen percent. Social phobia, generalized anxiety disorder and separation anxiety disorder are included in the triad of paediatric anxiety disorders. Specific phobia, obsessive compulsive disorder and post-traumatic stress disorder are also commonly seen in children. Overprotection by parents, parental death or separation, female sex, low educational status, family history of anxiety disorder, financial stress in family and adverse childhood experiences are risk factors for the development of anxiety disorders. If not diagnosed and managed at the earliest, paediatric anxiety disorders can cause life threatening problems in the future. Hence early and scientific management of anxiety disorders is essential. Cognitive behavioural therapy is the effective evidence based treatment for paediatric anxiety disorders.

  1. EBV-positive B cell cerebral lymphoma 12 years after sex-mismatched kidney transplantation: post-transplant lymphoproliferative disorder or donor-derived lymphoma?

    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.

    Anecdotal case reports, amplified by mass media and internet-based opinion groups, have recently indicated vaccinations as possibly responsible for autoimmunity/lymphoproliferation development. Multiply vaccinated Italian military personnel (group 1, operating in Italy, group 2, operating in Lebanon) were followed-up for nine months to monitor possible post-vaccine autoimmunity/lymphoproliferation onset. No serious adverse event was noticed in both groups. Multivariate analysis of intergroup differences only showed a significant association between lymphocyte increase and tetanus/diphtheria vaccine administration. A significant post-vaccine decrease in autoantibody positivity was observed. Autoantibodies were also studied by microarray analysis of self-proteins in subjects exposed to ≥4 concurrent vaccinations, without observing significant difference among baseline and one and nine months post-vaccine. Moreover, HLA-A2 subjects have been analyzed for the possible CD8T-cell response to apoptotic self-epitopes, without observing significant difference between baseline and one month post-vaccine. Multiple vaccinations in young adults are safe and not associated to autoimmunity/lymphoproliferation onset during a nine-month-long follow-up. Copyright © 2017 Elsevier Inc. All rights reserved.

    T cell immunodeficiency plays an important role in the pathogenesis of posttransplant lymphoproliferative disease (PTLD) by permitting the unbridled expansion of Epstein-Barr virus (EBV)-infected B lymphocytes. However, factors other than T cell function may contribute to PTLD pathogenesis because PTLD infrequently develops even in the context of severe T cell immunodeficiency, and athymic mice that are T-cell-immunodeficient can reject EBV-immortalized cells. Here we report that PTLD tissues express significantly lower levels of IL-18, interferon-γ (IFN-γ), Mig, and RANTES compared to lymphoid tissues diagnosed with acute EBV-induced infectious mononucleosis, as assessed by semiquantitative RT-PCR analysis. Other cytokines and chemokines are expressed at similar levels. Immunohistochemistry confirmed that PTLD tissues contain less IL-18 and Mig protein than tissues with infectious mononucleosis. IL-18, primarily a monocyte product, promotes the secretion of IFN-γ, which stimulates Mig and RANTES expression. Both IL-18 and Mig display antitumor activity in mice involving inhibition of angiogenesis. These results document greater expression of IL-18, IFN-γ, Mig, and RANTES in lymphoid tissues with acute EBV-induced infectious mononucleosis compared to tissues with PTLD and raise the possibility that these mediators participate in critical host responses to EBV infection.

    Autoimmune lymphoproliferative syndrome (ALPS) usually presents in childhood with fever, nonmalignant splenomegaly and lymphadenopathy along with hemocytopenia. This case report describes a 10-year-old boy presenting with signs of autoimmune disease, splenomegaly, hepatomegaly and resistant hemocytopenia. Sirolimus controlled the relapsed thrombocytopenia after splenectomy. Sequencing of the FAS gene identified two spontaneous heterozygous mutations (c.234 T > G, p.D78E) (c.236dupA, p.P80Tfs*26). The boy's homozygous missense variation (c.2588G > A, p.G863D) (rs140184929) in UNC13D gene had been identified as being related to familial hemophagocytic lymphohistiocytosis (FHL). TCRαβ + CD4/CD8 double-negative T cells (markers of ALPS) were not significantly increased from the outset. Elevated cytokines, such as interferon (IFN)-γ, interleukin (IL)-6 and tumor necrosis factor α decreased to normal levels after splenectomy whereas IL-10 remained high. Immunological analysis of the patient revealed a marked depletion of forkhead-box P3 + expressing regulatory T cells (Treg) and Th17 cells. The obtained data demonstrate that mutations to FAS and UNC13D which result in overwhelming T-cell and macrophage activation, one associated with inhibited Treg cell development and a severe ALPS-like symptom. Therefore, we propose that variations of UND13D may be a risk factor of ALPS development. Copyright © 2017. Published by Elsevier B.V.

  11. X-Linked Lymphoproliferative Syndrome and Common Variable Immunodeficiency May Not Be Differentiated by SH2D1A and XIAP/BIRC4 Genes Sequence Analysis

    Full Text Available The X-linked lymphoproliferative syndrome (XLP is a rare, inherited immunodeficiency characterized by recurrent episodes of hemophagocytic lymphohistiocytosis, hypogammaglobulinemia, and/or lymphomas. Recently, X-linked inhibitor of apoptosis (XIAP/BIRC4 gene defects, in families with XLP but without SH2D1A gene defects, has been defined. The distinction from primary immunodeficiencies with a defined genetic cause is mandatory. A six-year-old male patient was admitted with the complaints of persistent general lymphadenopathy, for two years had fever, bilateral cervical multiple microlymphadenopathy, hepatic/splenic enlargement with laboratory findings as decreased serum immunoglobulins, negative EBV VCA IgM (viral capsid antigen and anti-EBV EA (antibody to early D antigen, positive EBV VCA IgG (viral capsid antigen and EBV EBNA (antibody to nuclear antigen. SH2D1A gene analysis was negative. XIAP/BIRC4 sequencing revealed two novel single nucleotide variants (exon 7, 1978G > A, and 1996T > A in the 3′UTR of the gene in both patient and mother which were not disease causing. XIAP protein expression was found to be normal. The clinical and laboratory resemblance, no gene mutations, and normal XIAP protein expression led us to think that there may be another responsible gene for XLP. The patient will to be followed up as CVID until he presents new diagnostic signs or until the identification of a new gene.

    Law enforcement detectives who work with traumatized individuals, especially children who were victims of sexual abuse or assault, are likely to experience job-related emotional distress. The purpose of this study was to examine the relations among compassion fatigue, probable PTSD symptoms, and personal relationship satisfaction, including communication and sexual satisfaction, in a sample of 47 male and female detectives. Responses to the administered questionnaires indicated a relation between compassion fatigue symptoms and probable PTSD symptoms. There also were compelling gender differences. For example, for male detectives, open communication with their spouse or significant other was negatively correlated with burnout, indicating the more open the communication, the lower the reported burnout. However for female detectives there was a negative correlation between open communication with spouse or significant other and compassion satisfaction, suggesting that more open communication was related to lower levels of satisfaction with their ability to be a professional caregiver Furthermore, although stepwise regression analysis indicated that years of service as a detective is independently associated with sexual desire, female detectives evidenced less sexual desire and more difficulty with sexual functioning than did male detectives. Implications of these preliminary findings are discussed and limitations addressed.

  17. Suicides and Suicide Attempts during Long-Term Treatment with Antidepressants: A Meta-Analysis of 29 Placebo-Controlled Studies Including 6,934 Patients with Major Depressive Disorder.

    It is unclear whether antidepressants can prevent suicides or suicide attempts, particularly during long-term use. We carried out a comprehensive review of long-term studies of antidepressants (relapse prevention). Sources were obtained from 5 review articles and by searches of MEDLINE, PubMed Central and a hand search of bibliographies. We meta-analyzed placebo-controlled antidepressant RCTs of at least 3 months' duration and calculated suicide and suicide attempt incidence rates, incidence rate ratios and Peto odds ratios (ORs). Out of 807 studies screened 29 were included, covering 6,934 patients (5,529 patient-years). In total, 1.45 suicides and 2.76 suicide attempts per 1,000 patient-years were reported. Seven out of 8 suicides and 13 out of 14 suicide attempts occurred in antidepressant arms, resulting in incidence rate ratios of 5.03 (0.78-114.1; p = 0.102) for suicides and of 9.02 (1.58-193.6; p = 0.007) for suicide attempts. Peto ORs were 2.6 (0.6-11.2; nonsignificant) and 3.4 (1.1-11.0; p = 0.04), respectively. Dropouts due to unknown reasons were similar in the antidepressant and placebo arms (9.6 vs. 9.9%). The majority of suicides and suicide attempts originated from 1 study, accounting for a fifth of all patient-years in this meta-analysis. Leaving out this study resulted in a nonsignificant incidence rate ratio for suicide attempts of 3.83 (0.53-91.01). Therapists should be aware of the lack of proof from RCTs that antidepressants prevent suicides and suicide attempts. We cannot conclude with certainty whether antidepressants increase the risk for suicide or suicide attempts. Researchers must report all suicides and suicide attempts in RCTs. © 2016 S.

  4. Construction of a YAC contig and STS map spanning 2.5 Mbp in Xq25, the critical region for the X-linked lymphoproliferative (XLP) gene

    Lanyi, A.; Li, B.F.; Li, S. [Univ. of Nebraska Medical Center, Omaha, NE (United States)] [and others

    1994-09-01

    X-linked lymphoproliferative disease (XLP) is characterized by a marked vulnerability in Epstein-Barr virus (EBV) infection. Infection of XLP patients with EBV invariably results in fatal mononucleosis, agammaglobulinemia or B-cell lymphoma. The XLP gene lies within a 10 cM region in Xq25 between DXS42 and DXS10. Initial chromosome studies revealed an interstitial, cytogenetically visible deletion in Xq25 in one XLP family (43-004). We estimated the size of the Xq25 deletion by dual laser flow karyotyping to involve 2% of the X chromosome, or approximately 3 Mbp of DNA sequences. To further delineate the deletion we performed a series of pulsed field gel electrophoresis (PFGE) analyses which showed that DXS6 and DXS100, two Xq25-specific markers, are missing from 45-004 DNA. Five yeast artificial chromosomes (YACs) from a chromosome X specific YAC library containing sequences deleted in patient`s 43-004 DNA were isolated. These five YACs did not overlap, and their end fragments were used to screen the CEPH MegaYAC library. Seven YACs were isolated from the CEPH MegaYAC library. They could be arranged into a contig which spans between DXS6 and DXS100. The contig contains a minimum of 2.5 Mbp of human DNA. A total of 12 YAC end clone, lambda subclones and STS probes have been used to order clones within the contig. These reagents were also used in Southern blot and patients showed interstitial deletions in Xq25. The size of these deletions range between 0.5 and 2.5 Mbp. The shortest deletion probably represents the critical region for the XLP gene.

    While the overall incidence of post-transplant lymphoproliferative disease (PTLD) in pediatric liver transplant recipients has been reported to be 4-11%, the long-term risk of PTLD associated with primary tacrolimus therapy is unknown. Therefore, in order to determine the incidence and long-term risk of PTLD, the present study examined 131 pediatric recipients who underwent liver transplantation (LTx) between October 1989 and December 1991 and received primary tacrolimus therapy. This cohort of children was evaluated over an extended time-period (until December 31 1996) with a mean follow-up of 6.3 yr. Actuarial Kaplan-Meier analysis was utilized to determine the risk of PTLD over time. The overall incidence of PTLD was 13% (17/131) with an average age of 4.3 +/- 0.75 yr at diagnosis. Pretransplant Epstein-Barr virus (EBV) serologies were negative in 82%, positive in 12%, and not available in 6% of the patients. The median time to diagnosis of PTLD post-Tx was 11.9 months (mean 16.4 +/- 3.9, range 1.7-63.0 months). Mean tacrolimus dose and plasma trough level (as evaluated by enzyme-linked immunosorbent assay [ELISA]) at the time of diagnosis was 0.32 +/- 0.06 mg/kg/day and 1.3 +/- 0.3 ng/mL, respectively. The cumulative long-term risk of PTLD was found to increase over time: 3% at 6 months, 8% at 1 yr, 12% at 2 yr, 14% at 3 yr, and 15% at 4 and 5 yr. Mortality from PTLD was 12% (two of 17 patients). Primary tacrolimus use in pediatric LTx has a long-term risk of PTLD approaching 15%, with the majority of episodes (78%) occurring in the first 2 yr, suggesting that intense EBV surveillance should occur early post-transplantation.

    Epstein-Barr virus (EBV) plays an important role in various diseases. EBV-associated lymphoproliferative disease (LPD) is a rare disease with a canceration tendency. It is difficult to differentiate LPD with involvement of digestive tract from Crohn disease due to similar clinical and endoscopic manifestations. We present a case report of multiple ulcers with esophagus, small bowel and the entire colon involved, proved to be NK-Cell LPD, developed into EBV-associated NK/T Cell lymphoma, in an immunocompetent man who was initially misdiagnosed as Crohn disease.This report underscores that intestinal ulcers should be cautiously diagnosed, for it sometimes could be a precancerous lesion.

    2013-10-01

    Primary tic disorders are complex, multifactorial disorders in which tics are accompanied by other sensory features and an array of comorbid behavioral disorders. Secondary tics are proportionally much less frequent, but their etiology is diverse. This review aims to guide clinicians in the recognition of the phenomenology, pathophysiology, and treatment of these disorders. Advances include greater phenomenologic insights, particularly of nonmotor (sensory) features; increased knowledge of disease mechanisms, particularly coming from neuropsychological, functional imaging, pathologic, and animal model studies; growing evidence on the efficacy of alpha-2 agonists and the newer generation of dopamine-modulating agents; and recent strides in the evaluation of cognitive-behavioral therapy and deep brain stimulation surgery. The correct diagnostic approach to tic disorders requires accurate historical gathering, a thorough neurologic examination, and detailed definition of the patient's psychopathologic profile. Treatment should always begin with individualized psychoeducational strategies. Although pharmacologic treatments remain beneficial for most patients, cognitive-behavioral treatments have thus far shown promising efficacy. Deep brain stimulation surgery should still be limited to adult patients refractory to pharmacotherapy and cognitive-behavioral therapy.

    The functional esophageal disorders include globus, rumination syndrome, and symptoms that typify esophageal diseases (chest pain, heartburn, and dysphagia). Factors responsible for symptom production are poorly understood. The criteria for diagnosis rest not only on compatible symptoms but also on exclusion of structural and metabolic disorders that might mimic the functional disorders. Additionally, a functional diagnosis is precluded by the presence of a pathology-based motor disorder or p...

    2017-07-01

    Lymphoproliferative disease virus (LPDV) is an oncogenic avian retrovirus that was previously thought to exclusively infect domestic turkeys but was recently shown to be widespread in Wild Turkeys ( Meleagris gallopavo ) throughout most of the eastern US. In commercial flocks, the virus spreads between birds housed in close quarters, but there is little information about potential risk factors for infection in wild birds. Initial studies focused on distribution of LPDV nationally, but investigation of state-level data is necessary to assess potential predictors of infection and detect patterns in disease prevalence and distribution. We tested wild turkey bone marrow samples (n=2,538) obtained from hunter-harvested birds in New York State from 2012 to 2014 for LPDV infection. Statewide prevalence for those 3 yr was 55% with a 95% confidence interval (CI) of 53-57%. We evaluated a suite of demographic, anthropogenic, and land cover characteristics with logistic regression to identify potential predictors for infection based on odds ratio (OR). Age (OR=0.16, 95% CI=0.13-0.19) and sex (OR=1.3, 95% CI=1.03-1.24) were strong predictors of LPDV infection, with juveniles less likely to test positive than adults, and females more likely to test positive than males. The number of birds released during the state's 40-yr translocation program (OR=0.993, 95% CI=0.990-0.997) and the ratio of agriculture to forest cover (OR=1.13, 95% CI=1.03-1.19) were also predictive of LPDV infection. Prevalence distribution was analyzed using dual kernel density smoothing to produce a risk surface map, combined with Kulldorff's spatial scan statistic and the Anselin Local Moran's I to identify statistically significant geographic clusters of high or low prevalence. These methods revealed the prevalence of LPDV was high (>50%) throughout New York State, with regions of variation and several significant clusters. We revealed new information about the risk factors and distribution of LPDV in New

    Insomnia is related to an increased risk of eating disorders, while eating disorders are related to more disrupted sleep. Insomnia is also linked to poorer treatment outcomes for eating disorders. However, over the last decade, studies examining sleep and eating disorders have relied on surveys, with no objective measures of sleep for anorexia nervosa or bulimia nervosa, and only actigraphy data for binge eating disorder. Sleep disturbance is better defined for night eating syndrome, where sleep efficiency is reduced and melatonin release is delayed. Studies that include objectively measured sleep and metabolic parameters combined with psychiatric comorbidity data would help identify under what circumstances eating disorders and sleep disturbance produce an additive effect for symptom severity and for whom poor sleep would increase risk for an eating disorder. Cognitive behavior therapy for insomnia may be a helpful addition to treatment of those with both eating disorder and insomnia.

    Full Text Available The cerebellum has been considered for a long time to play a role solely in motor coordination. However, studies over the past two decades have shown that the cerebellum also plays a key role in many motor, cognitive, and emotional processes. In addition, studies have also shown that the cerebellum is implicated in many psychiatric disorders including attention deficit hyperactivity disorder, autism spectrum disorders, schizophrenia, bipolar disorder, major depressive disorder and anxiety disorders. In this review, we discuss existing studies reporting cerebellar dysfunction in various psychiatric disorders. We will also discuss future directions for studies linking the cerebellum to psychiatric disorders.

    This report defines criteria and reviews the epidemiology, pathophysiology, and management of the following common anorectal disorders: fecal incontinence (FI), functional anorectal pain, and functional defecation disorders. FI is defined as the recurrent uncontrolled passage of fecal material for at least 3 months. The clinical features of FI are useful for guiding diagnostic testing and therapy. Anorectal manometry and imaging are useful for evaluating anal and pelvic floor structure and function. Education, antidiarrheals, and biofeedback therapy are the mainstay of management; surgery may be useful in refractory cases. Functional anorectal pain syndromes are defined by clinical features and categorized into 3 subtypes. In proctalgia fugax, the pain is typically fleeting and lasts for seconds to minutes. In levator ani syndrome and unspecified anorectal pain, the pain lasts more than 30 minutes, but in levator ani syndrome there is puborectalis tenderness. Functional defecation disorders are defined by ≥2 symptoms of chronic constipation or irritable bowel syndrome with constipation, and with ≥2 features of impaired evacuation, that is, abnormal evacuation pattern on manometry, abnormal balloon expulsion test, or impaired rectal evacuation by imaging. It includes 2 subtypes: dyssynergic defecation and inadequate defecatory propulsion. Pelvic floor biofeedback therapy is effective for treating levator ani syndrome and defecatory disorders.

  3. Generalised anxiety disorder

    2013-10-01

    Full Text Available Generalised anxiety disorder is characterised by persistent, excessive and difficult-to-control worry, which may be accompanied by several psychic and somatic symptoms, including suicidality. Generalized anxiety disorder is the most common psychiatric disorder in the primary care, although it is often underrecognised and undertreated. Generalized anxiety disorder is typically a chronic condition with low short- and medium-term remission rates. Clinical presentations often include depression, somatic illness, pain, fatigue and problems sleeping. The evaluation of prognosis is complicated by frequent comorbidity with other anxiety disorders and depression, which worsen the long-term outcome and accompanying burden of disability. The two main treatments for generalised anxiety disorder are medications and psychotherapy. Selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors represent first-line psychopharmacologic treatment for generalised anxiety disorder. The most extensively studied psychotherapy for anxiety is cognitive behavioural therapy which has demonstrated efficacy throughout controlled studies.

  4. World Health Organization-defined eosinophilic disorders: 2017 update on diagnosis, risk stratification, and management.

    Science.gov (United States)

    Gotlib, Jason

    2017-11-01

    The eosinophilias encompass a broad range of nonhematologic (secondary or reactive) and hematologic (primary, clonal) disorders with potential for end-organ damage. Hypereosinophilia has generally been defined as a peripheral blood eosinophil count greater than 1500/mm 3 and may be associated with tissue damage. After exclusion of secondary causes of eosinophilia, diagnostic evaluation of primary eosinophilias relies on a combination of morphologic review of the blood and marrow, standard cytogenetics, fluorescent in situ-hybridization, flow immunocytometry, and T-cell clonality assessment to detect histopathologic or clonal evidence for an acute or chronic myeloid or lymphoproliferative disorder. Disease prognosis relies on identifying the subtype of eosinophilia. After evaluation of secondary causes of eosinophilia, the 2016 World Health Organization endorses a semi-molecular classification scheme of disease subtypes which includes the major category "myeloid/lymphoid neoplasms with eosinophilia and rearrangement of PDGFRA, PDGFRB, or FGFR1 or with PCM1-JAK2," and the "MPN subtype, chronic eosinophilic leukemia, not otherwise specified" (CEL, NOS). Lymphocyte-variant hypereosinophilia is an aberrant T-cell clone-driven reactive eosinophila, and idiopathic hypereosinophilic syndrome (HES) is a diagnosis of exclusion. The goal of therapy is to mitigate eosinophil-mediated organ damage. For patients with milder forms of eosinophilia (e.g., watch and wait approach with close-follow-up may be undertaken. Identification of rearranged PDGFRA or PDGFRB is critical because of the exquisite responsiveness of these diseases to imatinib. Corticosteroids are first-line therapy for patients with lymphocyte-variant hypereosinophilia and HES. Hydroxyurea and interferon-alpha have demonstrated efficacy as initial treatment and steroid-refractory cases of HES. In addition to hydroxyurea, second line cytotoxic chemotherapy agents and hematopoietic cell transplant have been used

  9. Genetics of bipolar disorder

    2014-02-01

    Full Text Available Berit Kerner Semel Institute for Neuroscience and Human Behavior, University of California, Los Angeles, Los Angeles, CA, USA Abstract: Bipolar disorder is a common, complex genetic disorder, but the mode of transmission remains to be discovered. Many researchers assume that common genomic variants carry some risk for manifesting the disease. The research community has celebrated the first genome-wide significant associations between common single nucleotide polymorphisms (SNPs and bipolar disorder. Currently, attempts are under way to translate these findings into clinical practice, genetic counseling, and predictive testing. However, some experts remain cautious. After all, common variants explain only a very small percentage of the genetic risk, and functional consequences of the discovered SNPs are inconclusive. Furthermore, the associated SNPs are not disease specific, and the majority of individuals with a “risk” allele are healthy. On the other hand, population-based genome-wide studies in psychiatric disorders have rediscovered rare structural variants and mutations in genes, which were previously known to cause genetic syndromes and monogenic Mendelian disorders. In many Mendelian syndromes, psychiatric symptoms are prevalent. Although these conditions do not fit the classic description of any specific psychiatric disorder, they often show nonspecific psychiatric symptoms that cross diagnostic boundaries, including intellectual disability, behavioral abnormalities, mood disorders, anxiety disorders, attention deficit, impulse control deficit, and psychosis. Although testing for chromosomal disorders and monogenic Mendelian disorders is well established, testing for common variants is still controversial. The standard concept of genetic testing includes at least three broad criteria that need to be fulfilled before new genetic tests should be introduced: analytical validity, clinical validity, and clinical utility. These criteria are

    Gastrointestinal motility disorders in the pediatric population are common and can range from benign processes to more serious disorders. Performing and interpreting motility evaluations in children present unique challenges. There are primary motility disorders but abnormal motility may be secondary due to other disease processes. Diagnostic studies include radiographic scintigraphic and manometry studies. Although recent advances in the genetics, biology, and technical aspects are having an important impact and have allowed for a better understanding of the pathophysiology and therapy for gastrointestinal motility disorders in children, further research is needed to be done to have better understanding of the pathophysiology and for better therapies.

    Addictive disorders in youth represent a dynamic field characterized by shifting patterns of substance use and high rates of experimentation, while retaining the risky behaviors and negative outcomes associated with established drug classes. Youth/adolescents are also at the forefront of use of new technologies, and non-substance-related disorders are pertinent. These disorders present with similar pictures of impairment, and can be diagnosed following the same principles. An underlying mental disorder and the possibility of a dual diagnosis need to be assessed carefully, and optimal treatment includes psychosocial treatments with applicable pharmacologic management, the latter representing an expanding field.

    To provide an overview of paraneoplastic autoimmune disorders presenting with various movement disorders. The spectrum of paraneoplastic autoimmune disorders has been expanding with the discovery of new antibodies against cell surface and intracellular antigens. Many of these paraneoplastic autoimmune disorders manifest as a form of movement disorder. With the discovery of new neuronal antibodies, an increasing number of idiopathic or neurodegenerative movement disorders are now being reclassified as immune-mediated movement disorders. These include anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis which may present with orolingual facial dyskinesia and stereotyped movements, CRMP-5 IgG presenting with chorea, anti-Yo paraneoplastic cerebellar degeneration presenting with ataxia, anti-VGKC complex (Caspr2 antibodies) neuromyotonia, opsoclonus-myoclonus-ataxia syndrome, and muscle rigidity and episodic spasms (amphiphysin, glutamic acid decarboxylase, glycine receptor, GABA(A)-receptor associated protein antibodies) in stiff-person syndrome. Movement disorders may be a presentation for paraneoplastic autoimmune disorders. Recognition of these disorders and their common phenomenology is important because it may lead to the discovery of an occult malignancy. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2010-04-01

    We propose some reflexions on the validity of the conceptualization of panic disorder, its nosographical place, and its clinical homogeneity, through the study of the frequency of some of its psychiatric comorbidities. To define a panic attack, DSM IV requires a number of symptoms which vary from four to 13. However, some patients suffer from panic attacks with less than four symptoms (paucisymptomatic attacks) and which fill the other criteria of panic disorder. These patients would have a biological vulnerability, familial antecedents, and a treatment response which are similar to those that fill the criteria of the panic attack according to the DSM. Some authors differentiate the panic disorder in several sub-groups, such as the panic disorder with cardiorespiratory symptoms, or vestibular symptoms, or cognitive symptoms. This division of the panic disorder in several sub-groups would have an interest in the knowledge of the etiopathogeny, the attacks' frequency, the disorder severity and the treatment response. Panic disorder with prevalent somatic expression includes crises without cognitive symptoms. This sub-type can be common in the medical context, especially in cardiology, but it is often ignored, at the price of loss of socio-professional adaptability, and a medical overconsumption. The relationship between panic disorder and agoraphobia appears to be the subject of controversies. According to the behavioral theory, phobic disorder is the primum movens of the sequence of appearance of the disorders. American psychiatry considers agoraphobia as a secondary response to the panic disorder, and pleads for a central role of panic attacks as an etiopathogenic factor in the development of agoraphobia. The distinction between panic disorder and generalized anxiety disorder can be difficult. This is due to the existence of paucisymptomatic panic attacks. Their paroxystic nature is difficult to distinguish from the fluctuations of the generalized anxiety disorder

    Abstract Health Issue Eating disorders are an increasing public health problem among young women. Anorexia and bulimia may give rise to serious physical conditions such as hypothermia, hypotension, electrolyte imbalance, endocrine disorders, and kidney failure. Key Issues Eating disorders are primarily a problem among women. In Ontario in 1995, over 90% of reported hospitalized cases of anorexia and bulimia were women. In addition to eating disorders, preoccupation with weight, body image and...

    2013-01-01

    The rationale, research literature, and proposed changes to the dissociative disorders and conversion disorder in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) are presented. Dissociative identity disorder will include reference to possession as well as identity fragmentation, to make the disorder more applicable to culturally diverse situations. Dissociative amnesia will include dissociative fugue as a subtype, since fugue is a rare disorder that always involves amnesia but does not always include confused wandering or loss of personality identity. Depersonalization disorder will include derealization as well, since the two often co-occur. A dissociative subtype of posttraumatic stress disorder (PTSD), defined by the presence of depersonalization or derealization in addition to other PTSD symptoms, is being recommended, based upon new epidemiological and neuroimaging evidence linking it to an early life history of adversity and a combination of frontal activation and limbic inhibition. Conversion disorder (functional neurological symptom disorder) will likely remain with the somatic symptom disorders, despite considerable dissociative comorbidity.

  7. Neoclassical transport including collisional nonlinearity.

    Candy, J; Belli, E A

    2011-06-10

    In the standard δf theory of neoclassical transport, the zeroth-order (Maxwellian) solution is obtained analytically via the solution of a nonlinear equation. The first-order correction δf is subsequently computed as the solution of a linear, inhomogeneous equation that includes the linearized Fokker-Planck collision operator. This equation admits analytic solutions only in extreme asymptotic limits (banana, plateau, Pfirsch-Schlüter), and so must be solved numerically for realistic plasma parameters. Recently, numerical codes have appeared which attempt to compute the total distribution f more accurately than in the standard ordering by retaining some nonlinear terms related to finite-orbit width, while simultaneously reusing some form of the linearized collision operator. In this work we show that higher-order corrections to the distribution function may be unphysical if collisional nonlinearities are ignored.

    2016-01-01

    The aim of this paper was to characterise nonspecific eating disorders (other than anorexia nervosa and bulimia nervosa). The Medline database was searched for articles on nonspecific eating disorders. The following disorders were described: binge eating disorder (BED), pica, rumination disorder, avoidant/restrictive food intake disorder, night eating syndrome (NES), sleep-related eating disorder (SRED), bigorexia, orthorexia, focusing on diagnosis, symptoms, assessment, comorbidities, clinical implications and treatment. All of the included disorders may have dangerous consequences, both somatic and psychological. They are often comorbid with other psychiatric disorders. Approximately a few percent of general population can be diagnosed with each disorder, from 0.5-4.7% (SRED) to about 7% (orthorexia). With the growing literature on the subject and changes in DSM-5, clinicians recognise and treat those disorders more often. More studies have to be conducted in order to differentiate disorders and treat or prevent them appropriately.

  10. Diffraction by disordered polycrystalline fibers

    Stroud, W.J.; Millane, R.P.

    1995-01-01

    X-ray diffraction patterns from some polycrystalline fibers show that the constituent microcrystallites are disordered. The relationship between the crystal structure and the diffracted intensities is then quite complicated and depends on the precise kind and degree of disorder present. The effects of disorder on diffracted intensities must be included in structure determinations using diffraction data from such specimens. Theory and algorithms are developed here that allow the full diffraction pattern to be calculated for a disordered polycrystalline fiber made up of helical molecules. The model accommodates various kinds of disorder and includes the effects of finite crystallite size and cylindrical averaging of the diffracted intensities from a fiber. Simulations using these methods show how different kinds, or components, of disorder produce particular diffraction effects. General properties of disordered arrays of helical molecules and their effects on diffraction patterns are described. Implications for structure determination are discussed. (orig.)

    There is growing evidence supporting a multifactorial etiology that includes genetic, neurochemical, and physiological components for eating disorders above and beyond the more conventional theories based on psychological and sociocultural factors. Ghrelin is one of the key gut signals associated with appetite, and the only known circulating hormone that triggers a positive energy balance by stimulating food intake. This review summarizes recent findings and several conflicting reports on ghrelin in eating disorders. Understanding these findings and inconsistencies may help in developing new methods to prevent and treat patients with these disorders. PMID:22960103

    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.

    Full Text Available Personality disorders are common in subjects with panic disorder. Personality disorders have shown to affect the course of panic disorder. The purpose of this study was to examine which personality disorders effect clinical severity in subjects with panic disorder. This study included 122 adults (71 female, 41 male, who met DSM-IV criteria for panic disorder (with or without agoraphobia. Clinical assessment was conducted by using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I, the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II and the Panic and Agoraphobia Scale (PAS, Global Assessment Functioning Scale (GAF, Beck Depression Inventory (BDI, and State-Trait Anxiety Inventory (STAI. Patients who had a history of sexual abuse were assessed with Sexual Abuse Severity Scale. Logistic regressions were used to identify predictors of suicide attempts, suicidal ideation, agoraphobia, different panic attack symptoms, sexual abuse, and early onset of disorders. The rates of comorbid Axis I and Axis II psychiatric disorders were 80.3% and 33.9%, consecutively, in patients with panic disorder. Panic disorder patients with comorbid personality disorders had more severe anxiety, depression and agoraphobia symptoms, and had earlier ages of onset, and lower levels of functioning. The rates of suicidal ideation and suicide attempts were 34.8% and 9.8%, consecutively, in subjects with panic disorder. The rate of patients with panic disorder had a history of childhood sexual abuse was 12.5%. The predictor of sexual abuse was more than one comorbid Axis II diagnosis. The predictors of suicide attempt were comorbid paranoid and borderline personality disorders, and the predictor of suicidal ideation was major depressive disorder in subjects with panic disorder. In conclusion, this study documents that comorbid personality disorders increase the clinical severity of panic disorder. Patients with more than one

    Early life adversity (ELA) and post-traumatic stress disorder (PTSD) are associated with poorer psychological and physical health. Potential underlying mechanisms and mediators remain to be elucidated, and the lifestyle habits and characteristics of individuals with ELA and/or PTSD have not been fully explored. We investigated whether the presence of ELA and/or PTSD are associated with nutrition, physical activity, resting and sleeping and smoking. A cross-sectional sample of 151 males and females (age: 45.6±3.5 years, BMI: 30.0±7.1 kg/m(2)) underwent anthropometric measurements, as well as detailed questionnaires for dietary assessment, physical activity, resting and sleeping, smoking habits and psychosocial assessments. A prospective follow-up visit of 49 individuals was performed 2.5 years later and the same outcomes were assessed. ELA and PTSD were evaluated as predictors, in addition to a variable assessing the combined presence/severity of ELA-PTSD. Data were analyzed using analysis of covariance after adjusting for several socioeconomic, psychosocial and anthropometric characteristics. Individuals with higher ELA or PTSD severity were found to have a poorer diet quality (DASH score: p=0.006 and p=0.003, respectively; aHEI-2010 score: ELA p=0.009), including further consumption of trans fatty acids (ELA p=0.003); the differences were significantly attenuated null after adjusting mainly for education or income and/or race. Further, individuals with higher ELA severity reported less hours of resting and sleeping (p=0.043) compared to those with zero/lower ELA severity, and the difference remained significant in the fully adjusted model indicating independence from potential confounders. When ELA and PTSD were combined, an additive effect was observed on resting and sleeping (p=0.001); results remained significant in the fully adjusted model. They also consumed more energy from trans fatty acids (p=0.017) tended to smoke more (p=0.008), and have less physical

    2015-01-01

    Eating disorders, especially anorexia nervosa and bulimia nervosa have been classically described in young females in Western population. Recent research shows that they are also seen in developing countries including India. The classification of eating disorders has been expanded to include recently described conditions like binge eating disorder. Eating disorders have a multifactorial etiology. Genetic factor appear to play a major role. Recent advances in neurobiology have improved our understanding of these conditions and may possibly help us develop more effective treatments in future. Premorbid personality appears to play an important role, with differential predisposition for individual disorders. The role of cultural factors in the etiology of these conditions is debated. Culture may have a pathoplastic effect leading to non-conforming presentations like the non fat-phobic form of anorexia nervosa, which are commonly reported in developing countries. With rapid cultural transformation, the classical forms of these conditions are being described throughout the world. Diagnostic criteria have been modified to accommodate for these myriad presentations. Treatment of eating disorders can be quite challenging, given the dearth of established treatments and poor motivation/insight in these conditions. Nutritional rehabilitation and psychotherapy remains the mainstay of treatment, while pharmacotherapy may be helpful in specific situations. PMID:26330646

To update the scientific evidence published in 2004, from the 2nd International Consultation on Sexual Medicine pertaining to the diagnosis and treatment of women's sexual pain disorders. An expert committee, invited from six countries by the 3rd International Consultation, was comprised of eight researchers and clinicians from biological and social science disciplines, for the purpose of reviewing and grading the scientific evidence on nosology, etiology, diagnosis, and treatment of women's sexual pain disorders. Expert opinion was based on grading of evidence-based medical literature, extensive internal committee discussion, public presentation, and debate. Results. A comprehensive assessment of medical, sexual, and psychosocial history is recommended for diagnosis and management. Indications for general and focused pelvic genital examination are identified. Evidence-based recommendations for assessment of women's sexual pain disorders are reviewed. An evidence-based approach to management of these disorders is provided. Continued efforts are warranted to conduct research and scientific reporting on the optimal assessment and management of women's sexual pain disorders, including multidisciplinary approaches.

    Full Text Available Skin picking disorder is not a dermatological disorder and it is a table characterized with picking skin excessively and repetitively, leading to damage in skin tissue. Unlike normal picking behaviour, psychogenic skin picking is repetitive and it can lead to severe damage in the skin and even complications which constitute vital danger. While some patients define frequent but short lasting picking attacks, others define rarer attacks which last a few hours. Skin picking disorder, which is not included in the classification systems up to DSM-5 as a separate diagnosis category, is included as an independent diagnosis in Obsessive Compulsive Disorder and Associated Disorders category in DSM-5. In case reports, open label studies and double blind studies selective serotonin reuptake inhibitors are shown to be effective in the treatment of skin picking disorder. Mostly, cognitive-behaviourial techniques are used and have been proven to be useful in psychotherapy. Habit reversal is one of the behaviourial techniques which are frequently applied, give positive results in which well-being state can be maintained.

    Over the last two decades, there have been numerous technical and methodological advances available to clinicians and researchers to better understand attention deficit hyperactivity disorder (ADHD) and its etiology. Despite the growing body of literature investigating the disorder’s pathophysiology, ADHD remains a complex psychiatric disorder to characterize. This chapter will briefly review the literature on ADHD, with a focus on its history, the current genetic insights, neurophysiologic theories, and the use of neuroimaging to further understand the etiology. We address some of the major concerns that remain unclear about ADHD, including subtype instability, heterogeneity, and the underlying neural correlates that define the disorder. We highlight that the field of ADHD is rapidly evolving; the descriptions provided here will hopefully provide a sturdy foundation for which to build and improve our understanding of the disorder.

    The phenomenology of dissociative disorders may be complex and sometimes confusing. We describe here two cases who were initially misdiagnosed. The first case concerned a 61 year-old woman, who was initially diagnosed as an isolated dissociative fugue and was actually suffering from severe major depressive episode. The second case concerned a 55 year-old man, who was suffering from type I bipolar disorder and polyvascular disease, and was initially diagnosed as dissociative fugue in a mooddestabilization context, while it was finally a stroke. Yet dissociative disorders as affective disorder comorbidity are relatively unknown. We made a review on this topic. Dissociative disorders are often studied through psycho-trauma issues. Litterature is rare on affective illness comorbid with dissociative disorders, but highlight the link between bipolar and dissociative disorders. The later comorbidity often refers to an early onset subtype with also comorbid panic and depersonalization-derealization disorder. Besides, unipolar patients suffering from dissociative symptoms have more often cyclothymic affective temperament. Despite the limits of such studies dissociative symptoms-BD association seems to correspond to a clinical reality and further works on this topic may be warranted. Copyright © 2014 L’Encéphale.

    Although meetings are central to organizational work, considerable time devoted to meetings in Academic Health Centers appears to be unproductively spent. The primary purposes of this article are to delineate and describe Meeting Disorders, pathological processes resulting in these inefficient and ineffective scenarios, and Meeting Fatigue Disorder (MFD), a clinical syndrome. The paper also offers preliminary approaches to remedies. The authors integrate observations made during tens of thousands of hours in administrative meetings in academic medical settings with information in the literature regarding the nature, causes and potential interventions for dysfunctional groups and meetings. Meeting Disorders, resulting from distinct pathologies of leadership and organization, constitute prevalent subgroups of the bureaucrapathologies, pathological conditions caused by dysfunctional bureaucratic processes that generate excesses of wasted time, effort, and other resources. These disorders also generate frustration and demoralization among participants, contributing to professional burnout. Meeting Fatigue Disorder (MFD) is a subjective condition that develops in individuals who overdose on these experiences and may reflect one manifestation of burnout. Meeting disorders and Meeting Fatigue Disorder occur commonly in bureaucratic life. Resources and potential remedies are available to help ameliorate their more deleterious effects.

    Conclusions. Our results suggest that the keystone of PTLD diagnosis is the clinical suspicion. Our study suggests that, in line with guidelines, EBV-VL assays may be avoided in low-risk patients in the absence of a strong clinical PTLD suspicion without increasing patients' risk of developing PTLD. This represents a safe and cost-saving clinical strategy for our center.

    Emotion dysregulation is a core feature of chronic complex dissociative disorders (DD), as it is for borderline personality disorder (BPD). Chronic complex DD include dissociative identity disorder (DID) and the most common form of dissociative disorder not otherwise specified (DDNOS, type 1), now known as Other Specified Dissociative Disorders (OSDD, type 1). BPD is a common comorbid disorder with DD, although preliminary research indicates the disorders have some distinguishing features as well as considerable overlap. This article focuses on the epidemiology, clinical presentation, psychological profile, treatment, and neurobiology of chronic complex DD with emphasis placed on the role of emotion dysregulation in each of these areas. Trauma experts conceptualize borderline symptoms as often being trauma based, as are chronic complex DD. We review the preliminary research that compares DD to BPD in the hopes that this will stimulate additional comparative research.

    Bipolar disorder refers to a group of affective disorders, which together are characterised by depressive and manic or hypomanic episodes. These disorders include: bipolar disorder type I (depressive and manic episodes: this disorder can be diagnosed on the basis of one manic episode); bipolar disorder type II (depressive and hypomanic episodes); cyclothymic disorder (hypomanic and depressive symptoms that do not meet criteria for depressive episodes); and bipolar disorder not otherwise specified (depressive and hypomanic-like symptoms that do not meet the diagnostic criteria for any of the aforementioned disorders). Bipolar disorder type II is especially difficult to diagnose accurately because of the difficulty in differentiation of this disorder from recurrent unipolar depression (recurrent depressive episodes) in depressed patients. The identification of objective biomarkers that represent pathophysiologic processes that differ between bipolar disorder and unipolar depression can both inform bipolar disorder diagnosis and provide biological targets for the development of new and personalised treatments. Neuroimaging studies could help the identification of biomarkers that differentiate bipolar disorder from unipolar depression, but the problem in detection of a clear boundary between these disorders suggests that they might be better represented as a continuum of affective disorders. Innovative combinations of neuroimaging and pattern recognition approaches can identify individual patterns of neural structure and function that accurately ascertain where a patient might lie on a behavioural scale. Ultimately, an integrative approach, with several biological measurements using different scales, could yield patterns of biomarkers (biosignatures) to help identify biological targets for personalised and new treatments for all affective disorders.

  14. Postmodern Stress Disorder (PMSD): A Possible New Disorder.

    Science.gov (United States)

    Eiser, Arnold R

    2015-11-01

    The murder of cardiovascular surgeon, Michael Davidson, MD, suggests the existence of a new disorder, postmodern stress disorder. This disorder is characterized by repetitive exposure to digital images of violence in a variety of electronic media, including films, television, video games, music videos, and other online sources. This disorder appears to be a variant of posttraumatic stress disorder, and shares with it excessive stimulation of the amygdala and loss of the normal inhibitory inputs from the orbitofrontal cingulate cortical gyrus. In postmodern stress disorder, repetitive digital microtraumas appear to have an effect similar to that of macrotraumas of warfare or civilian assaults. Other elements of the disorder include the development of fixed ideas of bullying or public shaming, access to weapons, and loss of impulse control. This syndrome could explain a number of previously inexplicable murders/suicides. Violence against health care professionals is a profound concern for the medical profession, as are assaults on nonclinicians. The recommendation is made to change forensic procedures to include obtaining historic information concerning the use of digital media during investigations of violent crimes and murders so that the disorder may be further characterized. Gaining an understanding of this disorder will require a multidisciplinary approach to this life-threatening public health problem. Research should also focus on the development and evaluation of possible antidotes to postmodern toxicities. Copyright © 2015 Elsevier Inc. All rights reserved.

    The somatoform disorders include a group of complex disorders consist of somatic symptoms for which there are no identifiable organic cause or pathogenetic mechanisms. Given the importance of these disorders and the need to clarify the diagnosis of somatoform disorder affecting the suicide risk, we took into consideration the scientific literature to investigate the correlation between the two conditions. We performed a bibliographic search through Medline, Embase, PsycINFO, Scopus, SciELO, ORCID, Google Scholar, DOAJ using the following terms: somatoform, somatization disorder, pain disorder AND psychological factor, suicide, parasuicide, suicidality. In all studies reported in our review, the suicidal behavior risk is high. But in the majority, the data are relatively unreliable because it takes into account the category nosographic "Neurotic, stress-related and somatoform disorders", too wide to be able to identify the clinical characteristics of patients at risk of only somatoform disorder. Several studies conclude that psychiatric comorbidity increases the suicide risk: patients with two or more psychiatric disorders are more likely to commit a suicide attempt; in particular if there is a axis I diagnosis, the risk reduplicate. The somatization disorder seems to have a significant psychiatric comorbidity in particular with anxious and affective disorders spectrum.

    The attention-deficit hyperactivity disorder is a common chronic disorder of childhood. No precise definition or approach to treatment is universally accepted; however, an extensive literature exists on which to base a rational approach to management. Symptomatic treatment with stimulant medication in selected patients is effective and safe, but not curative. Successful outcome depends on multimodality therapy, involving parents, teachers, and other professionals. Associated conditions, including learning disorders and emotional disturbance, must be identified and dealt with.

    Chronic Epstein-Barr virus-associated T/natural killer cell lymphoproliferative diseases represented by chronic active Epstein-Barr virus infection are lethal but are curable with several courses of chemotherapy and allogeneic hematopoietic stem cell transplantation (HSCT). Recently, we reported that reduced-intensity conditioning (RIC) provided better outcomes than myeloablative conditioning because RIC was less toxic. However, it was unclear whether cord blood transplantation (CBT) works in the context of RIC. We retrospectively analyzed 17 patients who underwent RIC followed by bone marrow transplantation (RIC-BMT) and 15 patients who underwent RIC followed by CBT (RIC-CBT). The representative regimen was fludarabine and melphalan based. The overall survival rates with RIC-BMT and RIC-CBT were 92.9% ± 6.9% and 93.3% ± 6.4%, respectively (P = .87). One patient died of lung graft-versus-host disease after RIC-BMT, and 1 patient died of multiple viral infections after RIC-CBT. Although cytotoxic chemotherapy was also immunosuppressive and might contribute to better donor cell engraftment after RIC-HSCT, the rate of engraftment failure after RIC-CBT was still higher than that after RIC-BMT (not significant); however, patients who had experienced graft failure were successfully rescued with a second HSCT. Unrelated cord blood can be an alternative source for RIC-HSCT if a patient has no family donor. Copyright © 2014 American Society for Blood and Marrow Transplantation. Published by Elsevier Inc.

    Epstein-Barr virus-associated hemophagocytic syndrome (EBV-AHS) is often associated with fatal infectious mononucleosis or T-cell lymphoproliferative diseases (LPD). To elucidate the true nature of fatal LPD observed in Herpesvirus papio (HVP)-induced rabbit hemophagocytosis, reactive or neoplastic, we analyzed sequential development of HVP-induced rabbit LPD and their cell lines. All of the seven Japanese White rabbits inoculated intravenously with HVP died of fatal LPD 18 to 27 days after inoculation. LPD was also accompanied by hemophagocytic syndrome (HPS) in five of these seven rabbits. Sequential autopsy revealed splenomegaly and swollen lymph nodes, often accompanied by bleeding, which developed in the last week. Atypical lymphoid cells infiltrated many organs with a "starry sky" pattern, frequently involving the spleen, lymph nodes, and liver. HVP-small RNA-1 expression in these lymphoid cells was clearly demonstrated by a newly developed in situ hybridization (ISH) system. HVP-ISH of immunomagnetically purified lymphoid cells from spleen or lymph nodes revealed HVP-EBER1+ cells in each CD4+, CD8+, or CD79a+ fraction. Hemophagocytic histiocytosis was observed in the lymph nodes, spleen, bone marrow, and thymus. HVP-DNA was detected in the tissues and peripheral blood from the infected rabbits by PCR or Southern blot analysis. Clonality analysis of HVP-induced LPD by Southern blotting with TCR gene probe revealed polyclonal bands, suggesting polyclonal proliferation. Six IL-2-dependent rabbit T-cell lines were established from transplanted scid mouse tumors from LPD. These showed latency type I/II HVP infection and had normal karyotypes except for one line, and three of them showed tumorigenicity in nude mice. These data suggest that HVP-induced fatal LPD in rabbits is reactive polyclonally in nature.

    This article presents an up-to-date summary of the genetic etiology, diagnostic criteria, clinical features, and current management recommendations for the most common neurocutaneous disorders encountered in clinical adult and pediatric neurology practices. The phakomatoses are a phenotypically and genetically diverse group of multisystem disorders that primarily affect the skin and central nervous system. A greater understanding of the genetic and biological underpinnings of numerous neurocutaneous disorders has led to better clinical characterization, more refined diagnostic criteria, and improved treatments in neurofibromatosis type 1, Legius syndrome, neurofibromatosis type 2, Noonan syndrome with multiple lentigines, tuberous sclerosis complex, Sturge-Weber syndrome, and incontinentia pigmenti. Neurologists require a basic knowledge of and familiarity with a wide variety of neurocutaneous disorders because of the frequent involvement of the central and peripheral nervous systems. A simple routine skin examination can often open a broad differential diagnosis and lead to improved patient care.

    2010-06-01

    In DSM-IV-TR, trichotillomania (TTM) is classified as an impulse control disorder (not classified elsewhere), skin picking lacks its own diagnostic category (but might be diagnosed as an impulse control disorder not otherwise specified), and stereotypic movement disorder is classified as a disorder usually first diagnosed in infancy, childhood, or adolescence. ICD-10 classifies TTM as a habit and impulse disorder, and includes stereotyped movement disorders in a section on other behavioral and emotional disorders with onset usually occurring in childhood and adolescence. This article provides a focused review of nosological issues relevant to DSM-V, given recent empirical findings. This review presents a number of options and preliminary recommendations to be considered for DSM-V: (1) Although TTM fits optimally into a category of body-focused repetitive behavioral disorders, in a nosology comprised of relatively few major categories it fits best within a category of motoric obsessive-compulsive spectrum disorders, (2) available evidence does not support continuing to include (current) diagnostic criteria B and C for TTM in DSM-V, (3) the text for TTM should be updated to describe subtypes and forms of hair pulling, (4) there are persuasive reasons for referring to TTM as "hair pulling disorder (trichotillomania)," (5) diagnostic criteria for skin picking disorder should be included in DSM-V or in DSM-Vs Appendix of Criteria Sets Provided for Further Study, and (6) the diagnostic criteria for stereotypic movement disorder should be clarified and simplified, bringing them in line with those for hair pulling and skin picking disorder.

    2007-01-01

    To update the reader on current research on stigmatizing attitudes towards people suffering from mood disorders and to describe recent interventions in this area. The public generally feels their own attitudes are more favourable to people with depression than 'most other people's' attitudes are. Among those with depressive symptoms, self-stigma in relation to depression is higher than perceived stigma from others, including professionals, thus hindering help seeking. The main factor that seems to improve the attitudes towards people with any mental illness is personal contact. Moderate improvements in attitudes have been achieved with an online intervention. Caution must be taken when ensuring that improvements in knowledge about mental disorders do not lead to increased social distance. There exists little research on stigmatizing attitudes towards people with mood disorders. Most of the literature on the stigma towards people with mental illness relates to people with more severe disorders such as schizophrenia. When research has been done on mood disorders, the focus has been on perceived stigma and self-stigma. No up-to-date research exists on discrimination experienced by people with mood disorders, and very little research exists on interventions designed to decrease stigmatizing attitudes towards them.

Comparatively small number of investigations were concerned with cognitive deficiencies accompanying the delusions. The substance of this study includes the detection of neuropsychological disfunctions in patients with persistent delusion disorder, and in tracing of these cognitive distortions to appropriate brain regions. Besides, characteristics of attribution style in these patients are analysed, from the aspect of their connections with unadjusted localized input for their reasoning system. The investigation is designed as a comparative study. The sample includes: a group of patients with persistent delusion disorder; a group of patients with paranoid schizophrenia; a group of healthy individuals. The participants have been tested by a neuropsychological battery that represents the following cognitive functions: attention, memory, vizuospatial and vizuoconstruction organization, executive ability, verbal divergent thinking. Projective Rorschach's method was used for estimation of attribution style.

    Chronic vaginitis is the most common vaginal disorder. Dogs with vaginitis show no signs of systemic illness but often lick at the vulva and have purulent or hemorrhagic vaginal discharges. Vaginitis is most commonly secondary to a noninfectious inciting factor such as congenital vaginal anomalies, clitoral hypertrophy, foreign bodies, trauma to the vaginal mucosa, or vaginal tumors. Inspection of the caudal vagina and vestibule both visually and digitally will often reveal the source of vaginal irritation. Vaginal cytology is used to establish the stage of the estrous cycle as well as distinguish uterine from vaginal sources of discharge. Vaginal cultures are used to establish the predominant offending organism associated with vaginal discharges and may be used as a guide for selection of a therapeutic agent. Vaginitis is best managed by removing the inciting cause and treating the area locally with antiseptic douches. Congenital malformations at the vestibulovaginal or vestibulovulvar junction may prevent normal intromission. Affected bitches may be reluctant to breed naturally because of pain. Such defects are detected best by digital examination. Congenital vaginal defects may be corrected by digital or surgical means. Prolapse of tissue through the lips of the vulva may be caused by clitoral hypertrophy, vaginal hyperplasia, or vaginal tumors. Enlargement of clitoral tissue is the result of endogenous or exogenous sources of androgens. Treatment of this condition includes removal of the androgen source and/or surgical removal of clitoral tissue. Vaginal hyperplasia is detected during proestrus or estrus of young bitches. Hyperplastic tissue will regress during diestrus. Tissue that is excessively traumatized and/or prolapse of the entire vaginal circumference may be removed surgically. Ovariohysterectomy may be used to prevent recurrence. Vaginal tumors are detected most often in older intact bitches. Such tumors are generally of smooth muscle or fibrous

  16. Using the mood disorder questionnaire and bipolar spectrum diagnostic scale to detect bipolar disorder and borderline personality disorder among eating disorder patients

    2013-01-01

    Background Screening scales for bipolar disorder including the Mood Disorder Questionnaire (MDQ) and Bipolar Spectrum Diagnostic Scale (BSDS) have been plagued by high false positive rates confounded by presence of borderline personality disorder. This study examined the accuracy of these scales for detecting bipolar disorder among patients referred for eating disorders and explored the possibility of simultaneous assessment of co-morbid borderline personality disorder. Methods Participants were 78 consecutive female patients who were referred for evaluation of an eating disorder. All participants completed the mood and eating disorder sections of the SCID-I/P and the borderline personality disorder section of the SCID-II, in addition to the MDQ and BSDS. Predictive validity of the MDQ and BSDS was evaluated by Receiver Operating Characteristic analysis of the Area Under the Curve (AUC). Results Fifteen (19%) and twelve (15%) patients fulfilled criteria for bipolar II disorder and borderline personality disorder, respectively. The AUCs for bipolar II disorder were 0.78 (MDQ) and 0.78 (BDSD), and the AUCs for borderline personality disorder were 0.75 (MDQ) and 0.79 (BSDS). Conclusions Among patients being evaluated for eating disorders, the MDQ and BSDS show promise as screening questionnaires for both bipolar disorder and borderline personality disorder.

    For the better understanding of esophageal motility, the muscle texture and the distribution of skeletal and smooth muscle fibers in the esophagus are of crucial importance. Esophageal physiology will be shortly mentioned as far as necessary for a comprehensive understanding of peristaltic disturbances. Besides the pure depiction of morphologic criteria, a complete esophageal study has to include an analysis of the motility. New diagnostic tools with reduced radiation for dynamic imaging (digital fluoroscopy, videofluoroscopy) at 4-30 frames/s are available. Radiomanometry is a combination of a functional pressure measurement and a simultaneous dynamic morphologic analysis. Esophageal motility disorders are subdivided by radiologic and manometric criteria into primary, secondary, and nonclassifiable forms. Primary motility disorders of the esophagus are achalasia, diffuse esophageal spasm, nutcracker esophagus, and the hypertonic lower esophageal sphincter. The secondary motility disorders include pseudoachalasia, reflux-associated motility disorders, functionally caused impactions, Boerhaave's syndrome, Chagas' disease, scleroderma, and presbyesophagus. The nonclassificable motility disorders (NEMD) are a very heterogeneous collective. (orig.) [de

    Full Text Available Metabolic disorders occurring in menopause, including dyslipidemia, disorders of carbohydrate metabolism (impaired glucose tolerance – IGT, type 2 diabetes mellitus – T2DM or components of metabolic syndrome, constitute risk factors for cardiovascular disease in women. A key role could be played here by hyperinsulinemia, insulin resistance and visceral obesity, all contributing to dyslipidemia, oxidative stress, inflammation, alter coagulation and atherosclerosis observed during the menopausal period. Undiagnosed and untreated, metabolic disorders may adversely affect the length and quality of women’s life. Prevention and treatment preceded by early diagnosis should be the main goal for the physicians involved in menopausal care. This article represents a short review of the current knowledge concerning metabolic disorders (e.g. obesity, polycystic ovary syndrome or thyroid diseases in menopause, including the role of a tailored menopausal hormone therapy (HT. According to current data, HT is not recommend as a preventive strategy for metabolic disorders in menopause. Nevertheless, as part of a comprehensive strategy to prevent chronic diseases after menopause, menopausal hormone therapy, particularly estrogen therapy may be considered (after balancing benefits/risks and excluding women with absolute contraindications to this therapy. Life-style modifications, with moderate physical activity and healthy diet at the forefront, should be still the first choice recommendation for all patients with menopausal metabolic abnormalities.

    Sleep disturbances are extremely prevalent in children with neurodevelopmental disorders compared to typically developing children. The diagnostic criteria for many neurodevelopmental disorders include sleep disturbances. Sleep disturbance in this population is often multifactorial and caused by the interplay of genetic, neurobiological and environmental overlap. These disturbances often present either as insomnia or hypersomnia. Different sleep disorders present with these complaints and based on the clinical history and findings from diagnostic tests, an appropriate diagnosis can be made. This review aims to provide an overview of causes, diagnosis, and treatment of sleep disturbances in neurodevelopmental disorders that present primarily with symptoms of hypersomnia and/or insomnia.

    The fifth edition of Diagnostic and Statistical Manual, the DSM-5 appeared officially in May 2013 during the development of the 166th Annual Meetingof the American Psychiatric Association (APA) in San Francisco. The drafting process was long and complex; much of the debate became public so that the expectations were great. And it must be said that the new edition did not disappoint, as many changes were made in relation to their predecessors. In Chapter of Anxiety Disorders, which is reviewed in this article, the changes were significant. Obsessive-compulsive disorder and Stress-related disorders were excluded and new clinical pictures, such as separation anxiety disorder and selective mutism, were included. And took place was the long awaited split between panic disorder and agoraphobia, now two separate disorders.

    Full Text Available This paper consists of a case history and an overview of the relationship, aetiology, and treatment of comorbid bipolar disorder migraine patients. A MEDLINE literature search was used. Terms for the search were bipolar disorder bipolar depression, mania, migraine, mood stabilizer. Bipolar disorder and migraine cooccur at a relatively high rate. Bipolar II patients seem to have a higher risk of comorbid migraine than bipolar I patients have. The literature on the common roots of migraine and bipolar disorder, including both genetic and neuropathological approaches, is broadly discussed. Moreover, bipolar disorder and migraine are often combined with a variety of other affective disorders, and, furthermore, behavioural factors also play a role in the origin and course of the diseases. Approach to treatment options is also difficult. Several papers point out possible remedies, for example, valproate, topiramate, which acts on both diseases, but no first-choice treatments have been agreed upon yet.

    Sheehan, Lindsay; Nieweglowski, Katherine; Corrigan, Patrick

    2016-01-01

    This article reviews the recent literature on the stigma of personality disorders, including an overview of general mental illness stigma and an examination of the personality-specific stigma. Overall, public knowledge of personality disorders is low, and people with personality disorders may be perceived as purposefully misbehaving rather than experiencing an illness. Health provider stigma seems particularly pernicious for those with borderline personality disorder. Most stigma research on personality disorders has been completed outside the USA, and few stigma-change interventions specific to personality disorder have been scientifically tested. Limited evidence suggests that health provider training can improve stigmatizing attitudes and that interventions combining positive messages of recovery potential with biological etiology will be most impactful to reduce stigma. Anti-stigma interventions designed specifically for health providers, family members, criminal justice personnel, and law enforcement seem particularly beneficial, given these sources of stigma.

Psychological aspects of functional disorders need special attention that may play an important role in patient management. Objectives In this study, psychology evaluation was performed for a population of patients with functional bowel disorders. Patients and Methods One hundred patients with functional bowel disorders including 50 patients with irritable bowel syndrome (IBS referred to GI clinics were candidates for psychiatry evaluation; of those 60 patients completed the study. Psychiatric disorders were diagnosed using a structured clinical interview based on diagnostic and statistical manual of mental disorders IV (DSM IV. Results Of 60 patients with functional bowel disorders (including 39 IBS, 51 (85% were diagnosed with at least one psychiatry disorder. The most common disorders were dysthymia (25% and obsessive-compulsive disorder (20%. There was no significant difference between IBS patients and other functional bowel disorders regarding the prevalence of psychiatric disorders. Conclusions Psychiatric disorders are very prevalent among patients with functional bowel disorders.

    Non-neoplastic disorders of the esophagus include esophagitis, esophageal diverticulum, esophageal injury, foreign body, fistulous formation between the esophagus and the surrounding structures and mucocele. Since these disorders have variable symptoms and radiologic findings, it needs to differentiated from other disorders other than esophageal diseases. Being knowledgeable of CT findings suggest that these disorders can help diagnose non-neoplastic disorders of the esophagus. The purpose of this pictorial essay is to review the CT appearance of non-neoplastic disorders of the esophagus.

    Use and misuse of cannabis and marihuana are frequent. About 5% of the adult population are current users but only 1.2% are dependent. The medical use of cannabis is controversial but there is some evidence for improvement of chronic pain and spasticity. The somatic toxicity of cannabis is well proven but limited and psychiatric disorders induced by cannabis are of more relevance, e.g. cognitive disorders, amotivational syndrome, psychoses and delusional disorders as well as physical and psychological dependence. The withdrawal symptoms are usually mild and do not require pharmacological interventions. To date there is no established pharmacotherapy for relapse prevention. Psychosocial interventions include psychoeducation, behavioral therapy and motivational enhancement. The CANDIS protocol is the best established German intervention among abstinence-oriented therapies.

    New Zealand is a developed geographically isolated country in the South Pacific with a population of 4.4 million. Genetic diagnosis is the standard of care for most patients with primary immunodeficiency disorders (PIDs). Since 2005, we have offered a comprehensive genetic testing service for PIDs and other immune-related disorders with a published sequence. Here we present results for this program, over the first decade, between 2005 and 2014. We undertook testing in 228 index cases and 32 carriers during this time. The three most common test requests were for X-linked lymphoproliferative (XLP), tumour necrosis factor receptor associated periodic syndrome (TRAPS) and haemophagocytic lymphohistiocytosis (HLH). Of the 32 suspected XLP cases, positive diagnoses were established in only 2 patients. In contrast, genetic defects in 8 of 11 patients with suspected X-linked agammaglobulinemia (XLA) were confirmed. Most XLA patients were initially identified from absence of B cells. Overall, positive diagnoses were made in about 23% of all tests requested. The diagnostic rate was lowest for several conditions with locus heterogeneity. Thorough clinical characterisation of patients can assist in prioritising which genes should be tested. The clinician-driven customised comprehensive genetic service has worked effectively for New Zealand. Next generation sequencing will play an increasing role in disorders with locus heterogeneity.

    This thesis describes the measurement of brain-tissue functions in patients with movement disorders using positron emission tomography (PET). This scanning technique is a method for direct in vivo quantitation of the regional tissue content of positron emitting radionuclides in brain (or other organs) in an essentially non-invasive way. Ch. 2 outlines some general features of PET and describes the scanner which has been used for the studies in this thesis. Also the tracer methodology, as applied to data investigations of movement disorders, are discussed. Ch. 3 contains the results of the PET investigations which were performed in the study of movement disorders. The results are presented in the form of 12 papers. The main goals of these studies were the understanding of the pathophysiology of Parkinson's disease, Huntington's chorea, Steele-Richardson-Olzewski syndrome and special case reports. Ch. 4 summarizes the results of these publications and Ch. 5 concludes the main part of this thesis with a general discussion of movement disorders in relation to PET investigations. 697 refs.; 60 figs.; 31 tabs

    Full Text Available Eating disorders are considered chronic diseases of civilization. The most studied and well known are anorexia and bulimia nervosa. Anorexia is considered one of the most common psychiatric problems of girls in puberty and adolescence. Due to high mortality and morbidity as well as the increasing expansion of these diseases, it is clear why the amount of research on these diseases is growing worldwide. Eating disorders lead to numerous medical complications, mostly due to late diagnosis. The main characteristic of these diseases is changed behavior in the nutrition, either as an intentional restriction of food, i.e. extreme dieting, or overeating, i.e. binge eating. Extreme dieting, skipping meals, self-induced vomiting, excessive exercise, and misuse of laxatives and diuretics for the purpose of maintaining or reducing body weight are characteristic forms of compensatory behavior of patients with eating disorder. The most appropriate course of treatment is determined by evaluating the patient’s health condition, associated with behavior and eating habits, the experience of one’s own body, character traits of personality, and consequently the development and functioning of the individual. The final treatment plan is individual. Eating disorders are a growing medical problem even in this part of the world. Prevention should be planned in cooperation with different sectors so as to stop the epidemic of these diseases.

    Full Text Available Hunger is an awakening related biological impulse. The relationship between hunger and sleep is moderated by the control of homeostatic and circadian rhytms of the body. Abnormal eating behavior during sleep period could result from different causes. Abnormal eating during the main sleep period has been categorized as either night eating syndrome or sleep related eating disorder. Night eating syndrome (NES is an eating disorder characterised by the clinical features of morning anorexia, evening hyperphagia, and insomnia with awakenings followed by nocturnal food ingestion. Recently night eating syndrome, conceptualized as a delayed circadian intake of food. Sleep-related eating disorder, thought to represent a parasomnia and as such included within the revised International Classification of Sleep Disorders (ICSD-2, and characterized by nocturnal partial arousals associated with recurrent episodes of involuntary food consumption and altered levels of consciousness. Whether, however, sleep-related eating disorder and night eating syndrome represent different diseases or are part of a continuum is still debated. This review summarizes their characteristics, treatment outcomes and differences between them.

    2014-01-01

    The relationship between creativity and bipolar disorder has been an intriguing topic since ancient times. Early studies focused on describing characteristics of creative people. From the last quarter of the twentieth century, researchers began to focus on the relationship between mood disorders and creativity. Initially, the studies were based on biographical texts and the obtained results indicated a relationship between these two concepts. The limitations of the retrospective studies led the researchers to develop systematic investigations into this area. The systematic studies that have focused on artistic creativity have examined both the prevalence of mood disorders and the creative process. In addition, a group of researchers addressed the relationship in terms of affective temperaments. Through the end of the 90's, the scope of creativity was widened and the notion of everyday creativity was proposed. The emergence of this notion led researchers to investigate the associations of the creative process in ordinary (non-artist) individuals. In this review, the descriptions of creativity and creative process are mentioned. Also, the creative process is addressed with regards to bipolar disorder. Then, the relationship between creativity and bipolar disorder are evaluated in terms of aforementioned studies (biographical, systematic, psychobiographical, affective temperaments). In addition, a new model, the "Shared Vulnerability Model" which was developed to explain the relationship between creativity and psychopathology is introduced. Finally, the methodological limitations and the suggestions for resolving these limitations are included.

    Epstein-Barr virus-associated hemophagocytic syndrome (EBV-AHS), which is often associated with fatal infectious mononucleosis or T-cell lymphoproliferative diseases (LPD), is a distinct disease characterized by high mortality. Treatment of patients with EBV-AHS has proved challenging. To develop some therapeutic interventions for EBV-AHS, we examined the effectiveness of an antiviral agent (vidarabine) or chemotherapy (CHOP), using a rabbit model for EBV-AHS. Fourteen untreated rabbits were inoculated intravenously with cell-free virions of the EBV-like virus Herpesvirus papio (HVP). All of the rabbits died of HVP-associated (LPD) and hemophagocytic syndrome (HPS) between 21 and 31 days after inoculation. Furthermore, three HVP-infected rabbits treated with vidarabine died between days 23 and 28 after inoculation, and their clinicopathological features were no different from those of untreated rabbits, indicating that this drug is not effective at all to treat HVP-induced rabbit LPD and HPS. Three of the infected rabbits that were treated with one course, with an incomplete set of three courses, or with three full courses of CHOP treatment died of HVP-induced LPD and HPS with a bleeding tendency and/or with opportunistic infections. They died on the 26th, 62nd and 105th day after virus inoculation, respectively. CHOP treatment transiently suppressed the HVP-induced LPD and contributed to the prolonged survival time of two infected rabbits. However, it did not remove all of the HVP-infected cells from the infected rabbits, and residual HVP-infected lymphocytes caused recurrences of rabbit LPD and HPS. The most interesting finding of this experiment was observed in the infected rabbit with the longest survival time of 105 days: HVP-negative lymphomas surrounded by HVP-induced LPD developed in the larynx and ileum of this rabbit, causing an obstruction of the lumen. We concluded that these were not secondary lymphomas caused by CHOP treatment, because no suspicious

    The most common neurological disorders, including neurodegenerative diseases and psychiatric disorders, have received recent attention with regards to pharmacogenomics and personalized medicine. Here, we will focus on a neglected neurodegenerative disorder, cerebral ischemic stroke (CIS), and highlight recent advances in two disorders, Parkinson's disease (PD) and Alzheimer's diseases (AD), that possess both similar and distinct mechanisms in regards to potential therapeutic targets. In the first part of this review, we will focus primarily on mechanisms that are somewhat specific to each disorder which are involved in neurodegeneration (i.e., protease pathways, calcium homeostasis, reactive oxygen species regulation, DNA repair mechanisms, neurogenesis regulation, mitochondrial function, etc.). In the second part of this review, we will discuss the applications of the genome-wide technology on pharmacogenomics of mental illnesses including schizophrenia (SCZ), autism spectrum disorders (ASD), attention deficit hyperactivity disorder (ADHD), and obsessive compulsive disorder (OCD).

    Full Text Available Lisa Lampe,1 Gin S Malhi2 1Discipline of Psychiatry, University of Newcastle, Newcastle, NSW, Australia; 2Discipline of Psychiatry, University of Sydney, Sydney, NSW, Australia Abstract: Avoidant personality disorder (AVPD is a relatively common disorder that is associated with significant distress, impairment, and disability. It is a chronic disorder with an early age at onset and a lifelong impact. Yet it is underrecognized and poorly studied. Little is known regarding the most effective treatment. The impetus for research into this condition has waxed and waned, possibly due to concerns regarding its distinctiveness from other disorders, especially social anxiety disorder (SAD, schizoid personality disorder, and dependent personality disorder. The prevailing paradigm subscribes to the “severity continuum hypothesis”, in which AVPD is viewed essentially as a severe variant of SAD. However, areas of discontinuity have been described, and there is support for retaining AVPD as a distinct diagnostic category. Recent research has focused on the phenomenology of AVPD, factors of possible etiological significance such as early parenting experiences, attachment style, temperament, and cognitive processing. Self-concept, avoidant behavior, early attachments, and attachment style may represent points of difference from SAD that also have relevance to treatment. Additional areas of research not focused specifically on AVPD, including the literature on social cognition as it relates to attachment and personality style, report findings that are promising for future research aimed at better delineating AVPD and informing treatment.

    Bisphenol A (BPA) is commonly used in the manufacturing of a wide range of consumer products, including polycarbonate plastics, epoxy resin that lines beverage and food cans, and some dental sealants. Consumption of food and beverages containing BPA represents the primary route of human BPA exposure, which is virtually ubiquitous. An increasing number of studies have evaluated the effects of BPA on immune responses in laboratory animals that have reported a variety of effects some of which have been contradictory. To address the divergent findings surrounding BPA exposure, a comprehensive chronic treatment study of BPA was conducted in Sprague-Dawley rats, termed the Consortium Linking Academic and Regulatory Insights on Toxicity of BPA (CLARITY-BPA). As a participant in the CLARITY-BPA project, our studies evaluated the effects of BPA on a broad range of immune function endpoints using spleen cells isolated from BPA or vehicle treated rats. This comprehensive assessment included measurements of lymphoproliferation in response to mitogenic stimuli, immunoglobulin production by B cells, and cellular activation of T cells, NK cells, monocytes, granulocytes, macrophages and dendritic cells. In total, 630 different measurements in BPA treated rats were performed of which 35 measurements were statistically different from vehicle controls. The most substantive alteration associated with BPA treatment was the augmentation of lymphoproliferation in response to pokeweed mitogen stimulations in 1 year old male rats, which was also observed in the reference estrogen ethinyl estradiol treated groups. With the exception of the aforementioned, the statistically significant changes associated with BPA treatment were mostly sporadic and not dose-dependent with only one out of five BPA dose groups showing a statistical difference. In addition, the observed BPA-associated alterations were mostly moderate in magnitude and showed no persistent trend over the one-year time period

    Increased use of serial EBV-PCR monitoring after pediatric transplantation has led to the identification of asymptomatic patients who carry very high viral loads over prolonged periods. The significance of this high-load state is unknown. We speculated that this state may identify patients at high risk for development of late PTLD/lymphoma. We reviewed data on 71 pediatric heart recipients who had serial viral load monitoring since 1997. Chronic high-load state was defined as the presence of >16,000 genome copies/mL whole blood on > or =50% of samples over at least 6 months. Among 20 high-load carriers (eight following prior PTLD, seven with prior symptomatic EBV infection, five without previous EBV disease), 9 (45%) developed late-onset PTLD 2.5-8.4 years posttransplant (including with four Burkitt's lymphoma). Among 51 controls with low (n = 39) or absent (n = 12) loads, only 2 (4%; p < 0.001 absent/low vs. high load) developed late PTLD/lymphoma. By multivariable analysis, high-load carrier state (OR = 12.4, 95% CI 2.1-74.4) and prior history of PTLD (OR = 10.7, 95% CI 1.9-60.6) independently predicted late PTLD. A chronic high EBV-load state is not benign and is a predictor of de novo or recurrent PTLD.

    Boysen, Guy; Ebersole, Ashley; Casner, Robert; Coston, Nykhala

    2014-01-01

    Research indicates that stereotypes can intersect. For example, the intersection of stereotypes about gender and mental disorders could result in perceptions of gendered mental disorders. In the current research, Studies 1 and 2 showed that people view specific disorders as being masculine or feminine. The masculine stereotype included antisocial personality disorder, addictions, and paraphilias. The feminine stereotype included eating disorders, histrionic personality disorder, body dysmorphia, and orgasmic disorder. In both studies, the perception of disorders as masculine was positively correlated with stigma. Study 3 showed that the positive correlation between masculinity and stigma also occurred when examining specific symptoms rather than full mental disorders. The findings provide further evidence for the intersection of stereotypes and indicate a novel factor in the understanding of stigma.

    The characteristic symptoms resulting from exposure to an extreme trauma include three clusters of symptoms: persistent experience of the traumatic event, persistent avoidance of stimuli associated with the trauma and persistent symptoms of increased arousal. Beyond the accepted clusters of symptoms for posttraumatic stress disorder exists a formation of symptoms related to exposure to extreme or prolonged stress e.g. childhood abuse, physical violence, rape, and confinement within a concentration camp. With accumulated evidence of the existence of these symptoms began a trail to classify a more complex syndrome, which included, but was not confined to the symptoms of posttraumatic stress disorder. This review addresses several subjects for study in complex posttraumatic stress disorder, which is a complicated and controversial topic. Firstly, the concept of complex posttraumatic stress disorder is presented. Secondly, the professional literature relevant to this disturbance is reviewed and finally, the authors present the polemic being conducted between the researchers of posttraumatic disturbances regarding validity, reliability and the need for separate diagnosis for these symptoms.

    Full Text Available The comorbidity of bipolar disorder and anxiety disorders is a well known concept. Obsessive-compulsive disorder is the most commonly seen comorbid anxiety disorder in bipolar patients. Some genetic variants, neurotransmitters especially serotonergic systems and second-messenger systems are thought to be responsible for its etiology. Bipolar disorder alters the clinical aspects of obsessive compulsive disorder and is associated with poorer outcome. The determination of comorbidity between bipolar disorder and obsessive compulsive disorder is quite important for appropriate clinical management and treatment.

    Full Text Available Abstract Background Obese and overweight people have a higher risk of both chronic physical illness and mental illness. Obesity is reported to be positively associated with psychiatric disorders, especially in people who seek obesity treatment. At the same time, obesity treatment may be influenced by psychological factors or personality characteristics. This study aimed to understand the prevalence of mental disorders among ethnic Chinese who sought obesity treatment. Methods Subjects were retrospectively recruited from an obesity treatment center in Taiwan. The obesity treatments included bariatric surgery and non-surgery treatment. All subjects underwent a standardized clinical evaluation with two questionnaires and a psychiatric referral when needed. The psychiatric diagnosis was made thorough psychiatric clinic interviews using the SCID. A total of 841 patients were recruited. We compared the difference in psychiatric disorder prevalence between patients with surgical and non-surgical treatment. Results Of the 841 patients, 42% had at least one psychiatric disorder. Mood disorders, anxiety disorders and eating disorders were the most prevalent categories of psychiatric disorders. Females had more mood disorders and eating disorders than males. The surgical group had more binge-eating disorder, adjustment disorder, and sleep disorders than the non-surgical group. Conclusion A high prevalence of psychiatric disorders was found among ethnic Chinese seeking obesity treatment. This is consistent with study results in the US and Europe.

    2016-01-01

    We consider Euclidean Conformal Field Theories perturbed by quenched disorder, namely by random fluctuations in their couplings. Such theories are relevant for second-order phase transitions in the presence of impurities or other forms of disorder. Theories with quenched disorder often flow to new fixed points of the renormalization group. We begin with disorder in free field theories. Imry and Ma showed that disordered free fields can only exist for d>4. For d>4 we show that disorder leads to new fixed points which are not scale-invariant. We then move on to large-N theories (vector models or gauge theories in the ‘t Hooft limit). We compute exactly the beta function for the disorder, and the correlation functions of the disordered theory. We generalize the results of Imry and Ma by showing that such disordered theories exist only when disorder couples to operators of dimension Δ>d/4. Sometimes the disordered fixed points are not scale-invariant, and in other cases they have unconventional dependence on the disorder, including non-trivial effects due to irrelevant operators. Holography maps disorder in conformal theories to stochastic differential equations in a higher dimensional space. We use this dictionary to reproduce our field theory results. We also study the leading 1/N corrections, both by field theory methods and by holography. These corrections are particularly important when disorder scales with the number of degrees of freedom.

    According to current proposals for ICD-11, stereotyped movement disorder will be classified in the grouping of neurodevelopmental disorders, with a qualifier to indicate whether self-injury is present, similar to the classification of stereotypic movement disorder in DSM-5. At the same time, the WHO ICD-11 Working Group on the Classification of Obsessive-Compulsive and Related Disorders has proposed a grouping of body-focused repetitive behavior disorders within the obsessive-compulsive and related disorders (OCRD) cluster to include trichotillomania and skin-picking disorder. DSM-5 has taken a slightly different approach: trichotillomania and excoriation (skin picking) disorder are included in the OCRD grouping, while body-focused repetitive behavior disorder is listed under other specified forms of OCRD. DSM-5 also includes a separate category of nonsuicidal self-injury in the section on "conditions for further study." There are a number of unresolved nosological questions regarding the relationships among stereotyped movement disorder, body-focused repetitive behavior disorders, and nonsuicidal self-injury. In this article, we attempt to provide preliminary answers to some of these questions as they relate to the ICD-11 classification of mental and behavioral disorders.

    The purpose of this study was to examine the effects of specific personality disorder comorbidity on the course of major depressive disorder in a nationally representative sample. Data were drawn from 1,996 participants in a national survey. Participants who met criteria for major depressive disorder at baseline in face-to-face interviews (in 2001-2002) were reinterviewed 3 years later (in 2004-2005) to determine persistence and recurrence. Predictors included all DSM-IV personality disorders. Control variables included demographic characteristics, other axis I disorders, family and treatment histories, and previously established predictors of the course of major depressive disorder. A total of 15.1% of participants had persistent major depressive disorder, and 7.3% of those who remitted had a recurrence. Univariate analyses indicated that avoidant, borderline, histrionic, paranoid, schizoid, and schizotypal personality disorders all elevated the risk for persistence. With axis I comorbidity controlled, all personality disorders except histrionic personality disorder remained significant. With all other personality disorders controlled, borderline and schizotypal disorders remained significant predictors. In final, multivariate analyses that controlled for age at onset of major depressive disorder, the number of previous episodes, duration of the current episode, family history, and treatment, borderline personality disorder remained a robust predictor of major depressive disorder persistence. Neither personality disorders nor other clinical variables predicted recurrence. In this nationally representative sample of adults with major depressive disorder, borderline personality disorder robustly predicted persistence, a finding that converges with recent clinical studies. Personality psychopathology, particularly borderline personality disorder, should be assessed in all patients with major depressive disorder, considered in prognosis, and addressed in treatment.

    Movement disorders are well known features of some dominant hereditary ataxias (HA), specially SCA3/Machado-Joseph disease and dentatorubropallidolusyan atrophy. However, little is known about the existence and classification of movement disorders in other dominant and recessive ataxias. We prospectively studied the presence of movement disorders in patients referred for HA over the last 3 years. Only those patients with a confirmed family history of ataxia were included. We studied 84 cases of HA, including 46 cases of recessive and 38 cases of dominant HA. Thirty out of 46 cases of recessive HA could be classified as: Friedreich ataxia (FA), 29 cases; vitamin E deficiency, 1 case. Twenty-three out of 38 cases of dominant HA could be classified as: SCA 2, 4 cases; SCA 3, 8 cases; SCA 6, 4 cases; SCA 7, 6 cases and SCA 8, 1 case. We observed movement disorders in 20/38 (52%) patients with dominant HA and 25/46 (54%) cases with recessive HA, including 16 patients (16/29) with FA. In general, postural tremor was the most frequent observed movement disorder (27 cases), followed by dystonia (22 cases). Five patients had akinetic rigid syndrome, and in 13 cases, several movement disorders coexisted. Movement disorders are frequent findings in HA, not only in dominant HA but also in recessive HA.

    Several movement disorders may occur during nocturnal rest disrupting sleep. A part of these complaints is characterized by relatively simple, non-purposeful and usually stereotyped movements. The last version of the International Classification of Sleep Disorders includes these clinical conditions (i.e. restless legs syndrome, periodic limb movement disorder, sleep-related leg cramps, sleep-related bruxism and sleep-related rhythmic movement disorder) under the category entitled sleep-related movement disorders. Moreover, apparently physiological movements (e.g. alternating leg muscle activation and excessive hypnic fragmentary myoclonus) can show a high frequency and severity impairing sleep quality. Clinical and, in specific cases, neurophysiological assessments are required to detect the presence of nocturnal movement complaints. Patients reporting poor sleep due to these abnormal movements should undergo non-pharmacological or pharmacological treatments.

    2013-01-01

    Developmental disorders, such as autism spectrum disorder and specific language impairment, are biologically based disorders that currently rely on behaviorally defined criteria for diagnosis and treatment. Specific behaviors that are included in diagnostic frameworks and the point at which individual differences in behavior constitute abnormality are largely arbitrary decisions. Such decisions are therefore likely to be strongly influenced by cultural values and expectations. This is evident in the dramatically different prevalence rates of autism spectrum disorder across countries and across different ethnic groups within the same country. In this article, we critically evaluate the understanding of developmental disorders from a cultural perspective. We specifically consider the challenges of applying diagnostic methods across cultural contexts, the influence of cultural values and expectations on the identification and treatment of children with suspected disorders, and how cross-cultural studies can help to refine cognitive theories of disorder that have been derived exclusively from Western North American and European investigations. Our review synthesizes clinical, cultural, and theoretical work in this area, highlighting potential universals of disorder and concluding with recommendations for future research and practice.

    Major psychiatric disorders, including attention deficit hyperactivity disorder (ADHD), autism (AUT), bipolar disorder (BD), major depressive disorder (MDD), and schizophrenia (SZ), are highly heritable and polygenic. Evidence suggests that these five disorders have both shared and distinct genetic risks and neural connectivity abnormalities. To measure aggregate genetic risks, the polygenic risk score (PGRS) was computed. Two independent general populations (N = 360 and N = 323) were separately examined to investigate whether the cross-disorder PGRS and PGRS for a specific disorder were associated with individual variability in functional connectivity. Consistent altered functional connectivity was found with the bilateral insula: for the left supplementary motor area and the left superior temporal gyrus with the cross-disorder PGRS, for the left insula and right middle and superior temporal lobe associated with the PGRS for autism, for the bilateral midbrain, posterior cingulate, cuneus, and precuneus associated with the PGRS for BD, and for the left angular gyrus and the left dorsolateral prefrontal cortex associated with the PGRS for schizophrenia. No significant functional connectivity was found associated with the PGRS for ADHD and MDD. Our findings indicated that genetic effects on the cross-disorder and disorder-specific neural connectivity of common genetic risk loci are detectable in the general population. Our findings also indicated that polygenic risk contributes to the main neurobiological phenotypes of psychiatric disorders and that identifying cross-disorder and specific functional connectivity related to polygenic risks may elucidate the neural pathways for these disorders.

    BACKGROUND AND AIMS: Binge eating disorder (BED) is a relatively common condition, especially in young adult females, and is characterized by chronic over-consumption of food resulting in embarrassment, distress, and potential health problems. It is formally included as a disorder in DSM-5...... use disorder, binging, obesity, food addiction, comorbidity, dopamine, opioid, serotonin, glutamate, and pharmacological treatment were the keywords used in searching. RESULTS: BED shares similar phenomenology to SUD, including significant urges to engage in binging episodes, resulting in distress...... and impairment. Similar neurobiological pathways are found in both BED and SUD and medications based on similar neurobiology have been examined for both disorders. A subset of individuals with BED may have a "food addiction", but there is no clinical agreement on the meaning of "food addiction". Exploring...

  16. Emerging Treatments in Eating Disorders.

    Eating disorders (EDs), including anorexia nervosa, bulimia nervosa, and binge-eating disorder, constitute a class of common and deadly psychiatric disorders. While numerous studies in humans highlight the important role of neurobiological alterations in the development of ED-related behaviors, the precise neural substrate that mediates this risk is unknown. Historically, pharmacological interventions have played a limited role in the treatment of eating disorders, typically providing symptomatic relief of comorbid psychiatric issues, like depression and anxiety, in support of the standard nutritional and psychological treatments. To date there are no Food and Drug Administration-approved medications or procedures for anorexia nervosa, and only one Food and Drug Administration-approved medication each for bulimia nervosa (fluoxetine) and binge-eating disorder (lisdexamfetamine). While there is little primary interest in drug development for eating disorders, postmarket monitoring of medications and procedures approved for other indications has identified several novel treatment options for patients with eating disorders. In this review, I utilize searches of the PubMed and ClinicalTrials.gov databases to highlight emerging treatments in eating disorders.

    Conversion disorder is characterized by functional impairment in motor, sensory, or neurovegetative systems that cannot be explained by a general medical condition. Diagnostic systems emphasize the absence of an organic basis for the dysfunction observed in conversion disorder. Nevertheless, there is a growing body of data on the specific functional brain correlates of conversion symptoms, particularly those obtained via neuroimaging and neurophysiological assessment. The present study aimed to determine if there are differences in measures of cognitive functioning between patients with conversion disorder and healthy controls. The hypothesis of the study was that the patients with conversion disorder would have poorer neurocognitive performance than the controls. The patient group included 43 patients diagnosed as conversion disorder and other psychiatric comorbidities according to DSM-IV-TR. Control group 1 included 44 patients diagnosed with similar psychiatric comorbidities, but not conversion diosorder, and control group 2 included 43 healthy individuals. All participants completed a sociodemographic questionnaire and were administered the SCID-I and a neuropsychological test battery of 6 tests, including the Serial Digit Learning Test (SDLT), Auditory Verbal Learning Test (AVLT), Wechsler Memory Scale, Stroop Color Word Interference Test, Benton Judgment of Line Orientation Test (BJLOT), and Cancellation Test. The patient group had significantly poorer performance on the SDLT, AVLT, Stroop Color Word Interference Test, and BJLOT than both control groups. The present findings highlight the differences between the groups in learning and memory, executive and visuospatial functions, and attention, which seemed to be specific to conversion disorder.

    2012-03-01

    Full Text Available Social Anxiety Disorder is a common disorder leading functional impairment. The comorbidity between mood disorders with social anxiety disorder is relatively common. This comorbidity impacts the clinical severity, resistance and functionality of patients. The systematic evaluation of the comorbidity in both patient groups should not be ignored and be carefully conducted. In general, social anxiety disorder starts at an earlier age than mood disorders and is reported to be predictor for subsequent major depression. The absence of comorbidity in patients with social anxiety disorder is a predictor of good response to treatment. In bipolar disorder patients with comorbid social anxiety disorder, there is an increased level of general psychopathology. Besides, they have poor outcome and increased risk of suicide. In this article, comorbidity between these two disorders has been evaluated in detail.

    The purposes of this study are to investigate the prevalence of major depressive disorder, panic disorder, and post-traumatic stress disorder (PTSD) in Korean subway drivers, and find the association between these disorders and the drivers' person-under-train (PUT) experiences. A total of 826 subway drivers who participated in a cross-sectional work and health survey were included for this study. The Korean version of the Composite International Diagnostic Interview 2.1 was applied to assess major depressive disorder, panic disorder, and PTSD. The date of PUT, whether victim died, and how many PUTs the drivers experienced were asked using a structured questionnaire. The standardized prevalence ratios (SPRs) for lifetime prevalence of panic disorder and PTSD in subway drivers were 13.3 (95 % confidence interval [CI] 6.6-22.4) and 2.1 (95 % CI 1.1-3.4), respectively. In lifetime prevalence, after adjusting for age, education, income, and working career, the drivers who experienced PUT had significantly higher risks for panic disorder (odds ratio [OR] = 4.2, 95 % CI 1.2-16.6) and PTSD (OR = 4.4, 95 % CI 1.3-16.4). In 1-year prevalence, the drivers who experienced PUT had a significantly higher risk for PTSD (OR = 11.7, 95 % CI 1.9-225.8). There was no significant value of SPR and OR in major depressive disorder. This study suggests that Korean subway drivers are at higher risk for panic disorder and PTSD compared to the general population, and PUT experience is associated with panic disorder and PTSD. Drivers who have experienced PUT should be treated quickly, sympathetically, and sensitively by a psychological professional and their colleagues, so they can return to work soon.

    Full Text Available Paulina Zelviene, Evaldas Kazlauskas Department of Clinical and Organizational Psychology, Vilnius University, Vilnius, Lithuania Abstract: Adjustment disorder (AjD is among the most often diagnosed mental disorders in clinical practice. This paper reviews current status of AjD research and discusses scientific and clinical issues associated with AjD. AjD has been included in diagnostic classifications for over 50 years. Still, the diagnostic criteria for AjD remain vague and cause difficulties to mental health professionals. Controversies in definition resulted in the lack of reliable and valid measures of AjD. Epidemiological data on prevalence of AjD is scarce and not reliable because prevalence data are biased by the diagnostic algorithm, which is usually developed for each study, as no established diagnostic standards for AjD are available. Considerable changes in the field of AjD could follow after the release of the 11th edition of International Classification of Diseases (ICD-11. A new AjD symptom profile was introduced in ICD-11 with 2 main symptoms as follows: 1 preoccupation and 2 failure to adapt. However, differences between the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and ICD-11 AjD diagnostic criteria could result in diverse research findings in the future. The best treatment approach for AjD remains unclear, and further treatment studies are needed to provide AjD treatment guidelines to clinicians.

    This report defines criteria and reviews the epidemiology, pathophysiology, and management of common anorectal disorders: fecal incontinence (FI), functional anorectal pain and functional defecation disorders. FI is defined as the recurrent uncontrolled passage of fecal material for at least 3 months. The clinical features of FI are useful for guiding diagnostic testing and therapy. Anorectal manometry and imaging are useful for evaluating anal and pelvic floor structure and function. Education, antidiarrheals and biofeedback therapy are the mainstay of management; surgery may be useful in refractory cases. Functional anorectal pain syndromes are defined by clinical features and categorized into three subtypes. In proctalgia fugax, the pain is typically fleeting and lasts for seconds to minutes. In levator ani syndrome (LAS) and unspecified anorectal pain the pain lasts more than 30 minutes, but in LAS there is puborectalis tenderness. Functional defecation disorders are defined by >2 symptoms of chronic constipation or irritable bowel syndrome with constipation, and with >2 features of impaired evacuation i.e., abnormal evacuation pattern on manometry, abnormal balloon expulsion test or impaired rectal evacuation by imaging. It includes two subtypes; dyssynergic defecation and inadequate defecatory propulsion. Pelvic floor biofeedback therapy is effective for treating LAS and defecatory disorders.

    2008-07-01

    Poor nutrition, overweight and obesity have increasingly become a public health concern as they affect many metabolic disorders, including heart disease, diabetes, digestive system disorders, and renal failure. Study of the effects of life style including healthy nutrition will help further elucidate the mechanisms involved in the adverse effects of poor nutrition. Unhealthy life style including poor nutrition can result in imbalance in our oxidation/redox systems. Lipids can undergo oxidative modification by lipoxygenases, cyclooxygenases, myeloperoxidase, and other enzymes. Oxidized phospholipids can induce inflammatory molecules in the liver and other organs. This can contribute to inflammation, leading to coronary heart disease, stroke, renal failure, inflammatory bowl disease, metabolic syndrome, bone and joint disorders, and even certain types of cancer. Our antioxidant and antiinflammatory defense mechanisms contribute to a balance between the stimulators and the inhibitors of inflammation. Beyond a point, however, these systems might be overwhelmed and eventually fail. High-density lipoprotein is a potent inhibitor of the formation of toxic oxidized lipids. High-density lipoprotein is also an effective system for stimulating the genes whose products are active in the removal, inactivation, and elimination of toxic lipids. Supporting the high-density lipoprotein function should help maintain the balance in these systems. It is hoped that the present report would elucidate some of the ongoing work toward this goal.

    2013-08-01

    Adult attention deficit/hyperactivity disorder (ADHD) is characterised by inattention and/or hyperactivity and impulsivity and is a frequent psychiatric disorder with childhood onset. In addition to core symptoms, patients often experience associated symptoms like emotional dysregulation or low self-esteem and suffer from comorbid disorders, particularly depressive episodes, substance abuse, anxiety or sleep disorders. It is recommended to include associated symptoms and comorbid psychiatric disorders in the diagnostic set-up and in the treatment plan. Comorbid psychiatric disorders should be addressed with disorder-specific therapies while associated symptoms also often improve with treatment of the ADHD core symptoms. The most impairing psychiatric disorder should be treated first. This review presents recommendations for differential diagnosis and treatment of adult ADHD with associated symptoms and comorbid psychiatric disorders with respect to internationally published guidelines, clinical trials and expert opinions. © Georg Thieme Verlag KG Stuttgart · New York.

    The criteria for borderline personality disorder seem to select patients with very high rates of Briquet's syndrome (hysteria), somatization disorder, antisocial personality disorder, and substance abuse disorders. This study was undertaken to determine whether systematic assessment of patients with borderline personality disorder would reveal characteristic features of that condition which would distinguish it from these other disorders. Eighty-seven white female patients (75 in St. Louis and 12 in Milan, Italy) who had borderline personality disorder according to both the DSM-III-R criteria and the Revised Diagnostic Interview for Borderlines were further examined with the DSM-III-R Checklist and the Perley-Guze Hysteria Checklist to determine their patterns of psychiatric comorbidity. Every patient had at least one additional DSM diagnosis. Patients in St. Louis and Milan averaged five and four additional diagnoses, respectively. Eighty-four percent of the patients in St. Louis met criteria for either somatization disorder, Briquet's syndrome, antisocial personality disorder, or substance abuse disorders. Patterns of comorbidity for panic (51%), generalized anxiety disorder (55%), and major depression (87%) in St. Louis were consistent with those in other studies. The data indicate that the boundaries for the borderline condition are not specific and identify a high percentage of patients with these other disorders. Furthermore, the comorbidity profiles closely resemble the psychiatric profiles of patients with these disorders. If the borderline syndrome is meant to include all of these disorders, its usefulness as a diagnosis is limited. Until the fundamental features of borderline personality disorder that distinguish it from the others are identified, it is recommended that clinicians carefully assess patients for these other diagnoses. Efforts should be made to change the borderline personality disorder criteria by shifting away from overlap with the

    Cannabis use in the adolescent population poses a significant threat of addiction potential resulting in altered neurodevelopment. There are multiple mechanisms of treatment of cannabis use disorder including behavioral therapy management and emerging data on treatment via pharmacotherapy. Recognizing the diagnostic criteria for cannabis use disorder, cannabis withdrawal syndrome, and mitigating factors that influence adolescent engagement in cannabis use allows for comprehensive assessment and management in the adolescent population.

    Conduct disorder (CD) is a frequently occurring psychiatric disorder characterized by a persistent pattern of aggressive and non-aggressive rule breaking antisocial behaviours that lead to considerable burden for the patients themselves, their family and society. This review paper updates diagnostic and therapeutic approaches to CD in the light of the forthcoming DSM-5 definition. The diagnostic criteria for CD will remain unchanged in DSM-5, but the introduction of a specifier of CD with a callous-unemotional (CU) presentation is new. Linked to this, we discuss the pros and cons of various other ways to subtype aggression/CD symptoms. Existing guidelines for CD are, with few exceptions, already of a relatively older date and emphasize that clinical assessment should be systematic and comprehensive and based on a multi-informant approach. Non-medical psychosocial interventions are recommended as the first option for the treatment of CD. There is a role for medication in the treatment of comorbid syndromes and/or in case of insufficient response to psychosocial interventions and severe and dangerous aggressive and violent behaviours.

    Objective The purpose of this study was to examine the effects of specific personality disorder co-morbidity on the course of major depressive disorder in a nationally-representative sample. Method Data were drawn from 1,996 participants in a national survey. Participants who met criteria for major depressive disorder at baseline in face-to-face interviews (2001–2002) were re-interviewed three years later (2004–2005) to determine persistence and recurrence. Predictors included all DSM-IV personality disorders. Control variables included demographic characteristics, other Axis I disorders, family and treatment histories, and previously established predictors of the course of major depressive disorder. Results 15.1% of participants had persistent major depressive disorder and 7.3% of those who remitted had a recurrence. Univariate analyses indicated that avoidant, borderline, histrionic, paranoid, schizoid, and schizotypal personality disorders all elevated the risk for persistence. With Axis I co-morbidity controlled, all but histrionic personality disorder remained significant. With all other personality disorders controlled, borderline and schizotypal remained significant predictors. In final, multivariate analyses that controlled for age at onset of major depressive disorder, number of previous episodes, duration of current episode, family history, and treatment, borderline personality disorder remained a robust predictor of major depressive disorder persistence. Neither personality disorders nor other clinical variables predicted recurrence. Conclusions In this nationally-representative sample of adults with major depressive disorder, borderline personality disorder robustly predicted persistence, a finding that converges with recent clinical studies. Personality psychopathology, particularly borderline personality disorder, should be assessed in all patients with major depressive disorder, considered in prognosis, and addressed in treatment.

    The personality disorders are commonly comorbid with the eating disorders. Personality disorder pathology is often suggested to impair the treatment of axis 1 disorders, including the eating disorders. This study examined whether personality disorder cognitions reduce the impact of cognitive behavioural therapy (CBT) for eating disorders, in terms of treatment dropout and change in eating disorder attitudes in the early stages of treatment. Participants were individuals with a diagnosed eating disorder, presenting for individual outpatient CBT. They completed measures of personality disorder cognitions and eating disorder attitudes at sessions one and six of CBT. Drop-out rates prior to session six were recorded. CBT had a relatively rapid onset of action, with a significant reduction in eating disorder attitudes over the first six sessions. Eating disorder attitudes were most strongly associated with cognitions related to anxiety-based personality disorders (avoidant, obsessive-compulsive and dependent). Individuals who dropped out of treatment prematurely had significantly higher levels of dependent personality disorder cognitions than those who remained in treatment. For those who remained in treatment, higher levels of avoidant, histrionic and borderline personality disorder cognitions were associated with a greater change in global eating disorder attitudes. CBT's action and retention of patients might be improved by consideration of such personality disorder cognitions when formulating and treating the eating disorders.

    2015-01-01

    Epilepsy, a disorder of unprovoked seizures is a multifaceted disease affecting individuals of all ages with a particular predilection for the very young and old. In addition to seizures, many patients often report cognitive and psychiatric problems associated with both the seizures themselves and its therapy. Epilepsy has numerous etiologies both idiopathic and acquired with a wide range of therapeutic responses. Despite numerous treatments available to control repetitive seizures including medications, diets, immunotherapy, surgery, and neuromodulatory devices, a large percentage of patients continue to suffer the consequences of uncontrolled seizures, which include psychosocial stigma and death.

    Full Text Available Oxytocin is a neuropeptide that plays critical role in mother-infant bonding, pair bonding and prosocial behaviors. Several neuropsychiatric disorders such as autism, schizophrenia, affective disorders, anxiety disorders, attention deficit/hyperactivity disorder, alcohol/substance addiction, aggression, suicide, eating disorders and personality disorders show abnormalities of oxytocin system. These findings have given rise to the studies searching therapeutic use of oxytocin for psychi-atric disorders. The studies of oxytocin interventions in psychiatric disorders yielded potentially promising findings. This paper reviews the role of oxytocin in emotions, behavior and its effects in psychiatric disorders. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2016; 8(2: 102-113

    2011-01-01

    Impulsivity is associated with mood instability, behavioral problems, and action without planning in patients with bipolar disorder. Increased impulsivity levels are reported at all types of mood episodes. This association suggests a high comorbidity between impulse control disorders (ICDs) and bipolar disorder. The aim of this study is to compare the prevalence of ICDs and associated clinical and sociodemographic variables in euthymic bipolar I patients. A total of 124 consecutive bipolar I patients who were recruited from regular attendees from the outpatient clinic of our Bipolar Disorder Unit were included in the study. All patients were symptomatically in remission. Diagnosis of bipolar disorder was confirmed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Impulse control disorders were investigated using the modified version of the Minnesota Impulsive Disorders Interview. Impulsivity was measured with the Barratt Impulsiveness Scale Version 11. Furthermore, all patients completed the Zuckerman Sensation-Seeking Scale Form V. The prevalence rate of all comorbid ICDs in our sample was 27.4% (n = 34). The most common ICD subtype was pathologic skin picking, followed by compulsive buying, intermittent explosive disorder, and trichotillomania. There were no instances of pyromania or compulsive sexual behavior. There was no statistically significant difference between the sociodemographic characteristics of bipolar patients with and without ICDs with regard to age, sex, education level, or marital status. Comorbidity of alcohol/substance abuse and number of suicide attempts were higher in the ICD(+) group than the ICD(-) group. Length of time between mood episodes was higher in the ICD(-) group than the ICD(+) group. There was a statistically significant difference between the total number of mood episodes between the 2 groups, but the number of depressive episodes was higher in the ICD(+) patients

    Network medicine considers networks among genes, diseases, and individuals. Networks of mental disorders remain poorly understood, despite their high comorbidity. In this study, a network of mental disorders in Korea was constructed to offer a complementary approach to treatment. Data on the prevalence and morbidity of mental disorders were obtained from the 2006 and 2011 Korean Epidemiologic Catchment Area Study, including 22 psychiatric disorders. Nodes in the network were disease phenotypes identified by Diagnostic and Statistical Manual of Mental Disorders-IV, and the links connected phenotypes showing significant comorbidity. Odds ratios were used to quantify the distance between disease pairs. Network centrality was analyzed with and without weighting of the links between disorders. Degree centrality was correlated with suicidal behaviors and use of mental health services. In 2011 and 2006, degree centrality was highest for major depressive disorder, followed by nicotine dependence and generalized anxiety disorder (2011) or alcohol dependence (2006). Weighted degree centrality was highest in conversion disorder in both years. Therefore, major depressive disorder and nicotine dependence are highly connected to other mental disorders in Korea, indicating their comorbidity and possibility of shared biological mechanisms. The use of networks could enhance the understanding of mental disorders to provide effective mental health services.

    Movement disorders can be defined as neurological syndromes presenting with excessive or diminished automatic or voluntary movements not related to weakness or spasticity. Both Parkinson's disease (PD) and Huntington's disease (HD) are well-known examples of these syndromes. The high prevalence of comorbid psychiatric symptoms like depression, anxiety, obsessive-compulsive symptoms, hallucinations, delusions, impulsivity, sleep disorders, apathy and cognitive impairment mean that these conditions must be regarded as neuropsychiatric diseases. In this article, we review neuroanatomical (structural and functional), psychopathological and neuropsychological aspects of PD and HD. The role of fronto-subcortical loops in non-motor functions is particularly emphasised in order to understand the clinical spectrum of both diseases, together with the influence of genetic, psychological and psychosocial aspects. A brief description of the main psychopharmacological approaches for both diseases is also included. Copyright © 2017 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    Full Text Available Active immunization of children has been proven very effective in elimination of life threatening complications of many infectious diseases in developed countries. However, as vaccination-preventable infectious diseases and their complications have become rare, the interest focuses on immunization-related adverse reactions. Unfortunately, fear of vaccination-related adverse effects can led to decreased vaccination coverage and subsequent epidemics of infectious diseases. This review includes reports about possible side effects following vaccinations in children with neurological disorders and also published recommendations about vaccinating children with neurological disorders. From all international published data anyone can conclude that vaccines are safer than ever before, but the challenge remains to convey this message to society.

    Numerous blood-related disorders will demonstrate skeletal alterations. These include various anemias, leukemias, lymphomas, and clotting-deficient diseases (hemophilia). Of all the various types of anemias only those that are chronic and severe will result in radiographically visible osseous changes. The skeletal alterations which are observed are invariably related to the direct effects on the bone marrow or are secondary to the inherent complications of the disease. The most notable osseous changes are seen in the congenital hemolytic anemias, especially thalassemia (Cooley's anemia), sickle cell anemia, and hereditary spherocytosis. Chronic iron deficiency anemia produces very minor skeletal changes, usually isolated to the skull. Leukemia demonstrates characteristic changes largely dependent on age. Hemophilia primarily alters joint function due to recurrent intraarticular hemorrhage. This chapter discusses blood-related disorders that affect the bones

    The relationship of Narcissistic Personality Disorder (NPD) to suicidal behavior is understudied. The modest body of existing research suggests that NPD is protective against low-lethality suicide attempts, but is associated with high lethality attempts. Mood-disordered patients (N = 657) received structured interviews including Axis I and II diagnosis and standardized clinical measures. Following chi-square and t-tests, a logistical regression model was constructed to identify predictors of suicide attempt. While there was no bivariate relationship of NPD on suicide attempt, in the logistic regression patients with NPD were 2.4 times less likely to make a suicide attempt (OR = 0.41; 95% CI = 0.19 - 0.88; p disorder, and to have high aggression and hostility scores. Limitations include that the sample consists of only mood-disordered patients, a modest sample size of NPD, and the data are cross-sectional. The multivariate protective effect of NPD on suicide attempt is consistent with most previous research. The lower impulsivity of NPD patients and less severe personality pathology relative to other personality disorders may contribute to this effect. No relationship of NPD to attempt lethality was found, contradicting other research, but perhaps reflecting differences between study samples. Future studies should oversample NPD patients and include suicide death as an outcome. Clinical implications include discussion of individualized suicide risk assessment with NPD patients.

    2018-01-01

    Avoidant personality disorder (AVPD) is a relatively common disorder that is associated with significant distress, impairment, and disability. It is a chronic disorder with an early age at onset and a lifelong impact. Yet it is underrecognized and poorly studied. Little is known regarding the most effective treatment. The impetus for research into this condition has waxed and waned, possibly due to concerns regarding its distinctiveness from other disorders, especially social anxiety disorder (SAD), schizoid personality disorder, and dependent personality disorder. The prevailing paradigm subscribes to the "severity continuum hypothesis", in which AVPD is viewed essentially as a severe variant of SAD. However, areas of discontinuity have been described, and there is support for retaining AVPD as a distinct diagnostic category. Recent research has focused on the phenomenology of AVPD, factors of possible etiological significance such as early parenting experiences, attachment style, temperament, and cognitive processing. Self-concept, avoidant behavior, early attachments, and attachment style may represent points of difference from SAD that also have relevance to treatment. Additional areas of research not focused specifically on AVPD, including the literature on social cognition as it relates to attachment and personality style, report findings that are promising for future research aimed at better delineating AVPD and informing treatment.

    2017-08-01

    Estimates of the frequencies of rare disorders vary from country to country; the global average defined prevalence is 40 per 100 000 (0.04%). Some occur in only one or a few patients. However, collectively rare disorders are fairly common, affecting 6-8% of the US population, or about 30 million people, and a similar number in the European Union. Most of them affect children and most are genetically determined. Diagnosis can be difficult, partly because of variable presentations and partly because few clinicians have experience of individual rare disorders, although they may be assisted by searching databases. Relatively few rare disorders have specific pharmacological treatments (so-called orphan drugs), partly because of difficulties in designing trials large enough to determine benefits and harms alike. Incentives have been introduced to encourage the development of orphan drugs, including tax credits and research aids, simplification of marketing authorization procedures and exemption from fees, and extended market exclusivity. Consequently, the number of applications for orphan drugs has grown, as have the costs of using them, so much so that treatments may not be cost-effective. It has therefore been suggested that not-for-profit organizations that are socially motivated to reduce those costs should be tasked with producing them. A growing role for patient organizations, improved clinical and translational infrastructures, and developments in genetics have also contributed to successful drug development. The translational discipline of clinical pharmacology is an essential component in drug development, including orphan drugs. Clinical pharmacologists, skilled in basic pharmacology and its links to clinical medicine, can be involved at all stages. They can contribute to the delineation of genetic factors that determine clinical outcomes of pharmacological interventions, develop biomarkers, design and perform clinical trials, assist regulatory decision

    Body dysmorphic disorder is a chronic psychiatric disorder characterized by excessive preoccupation with an absent or minimal physical deformity. It causes severe distress and impairs normal functioning. In the last centuries, this disorder has been mentioned in the medical literature by important mental health practitioners by different names, such as "dysmorphophobia" or "dermatologic hypochondriasis". However, not until the last century was it included among the obsessive-compulsive disorders, although its classification has changed over time.Patients with body dysmorphic disorder constantly seek cosmetic treatments in order to improve their physical appearance, which more often deteriorates their mental condition. The high prevalence of psychiatric disorders in cosmetic medical practice has led in this field of study to the new science "cosmetic psychodermatology". This paper presents a summary of important facts about body dysmorphic disorder and its description throughout the history of medicine.

  6. Strong mobility in weakly disordered systems

    2009-01-01

    We study transport of interacting particles in weakly disordered media. Our one-dimensional system includes (i) disorder, the hopping rate governing the movement of a particle between two neighboring lattice sites is inhomogeneous, and (ii) hard core interaction, the maximum occupancy at each site is one particle. We find that over a substantial regime, the root-mean-square displacement of a particle s grows superdiffusively with time t, {sigma}{approx}({epsilon}t){sup 2/3}, where {epsilon} is the disorder strength. Without disorder the particle displacement is subdiffusive, {sigma} {approx}t{sup 1/4}, and therefore disorder strongly enhances particle mobility. We explain this effect using scaling arguments, and verify the theoretical predictions through numerical simulations. Also, the simulations show that regardless of disorder strength, disorder leads to stronger mobility over an intermediate time regime.

    Full Text Available Abstract Background Adolescent onset bipolar disorder often presents with co-morbid disorders of which psychoactive substance use disorders are notable. Mania symptoms and co-morbid psychoactive substance use disorders prone adolescents with bipolar disorder to impulsivity, impaired judgment, and risk taking behavior which often includes sexual risk behavior. There are dearth of information on pattern of co-morbid disorders and sexual risk behavior in adolescent onset bipolar disorder in Nigeria. This study assessed the prevalence and pattern of co-morbid disorders and determined associated factors of sexual risk behavior among adolescents with bipolar disorder. Methods Socio-demographic information was obtained from the adolescents using socio-demographic questionnaire. Clinical interview, physical examination and laboratory investigations were employed to establish co-morbid disorders in these adolescents during the outpatient follow up visits over a one year period. Results A total of forty six (46 adolescents with bipolar disorder were followed up over a one year period. Twenty two (47.8% of the adolescents had co-morbid disorders with cannabis use disorders, alcohol use disorders, conduct disorder with or without other psychoactive substance use accounting for 23.9%, 8.7%, 13.0% respectively and HIV infection, though a chance finding accounting for 2.2%. Twenty one (45.7% of the adolescents had positive history of sexual risk behavior, which was significantly associated with presence of co-morbid disorders (p = 0.003, level of religion activities in the adolescents (p = 0.000, and marital status of the parents (p = 0.021. Conclusion When planning interventions for children and adolescents with bipolar disorder, special attention may need to be focused on group of adolescents with co-morbid disorders and propensity towards impulsivity and sexual risk behavior. This may help in improving long term outcome in this group of adolescents.

    We assessed the occurrence of co-morbid psychiatric disorders (i.e., problem drinking, anxiety, and depression) among college students who met the threshold for disordered gambling. The participants included a large sample of undergraduate students (n = 1,430) who were enrolled in an introductory health course at a large, southeastern university in Spring 2011 and completed an online assessment that included scales to assess disordered gambling, problem drinking, anxiety, and depression. We calculated screening scores, computed prevalence rates for each disorder, and calculated Pearson correlations and Chi square tests to examine correlations and co-morbid relationships between the four disorders. Analyses indicated that all disorders were significantly associated (p students who experience disordered gambling (and other psychiatric disorders) are at increased risk of experiencing co-occurring disorders, it might be useful for college health professionals to concurrently screen and intervene for co-occurring disorders.

    Motility disorders of the esophagus comprise a heterogeneous spectrum of diseases. Primary malformations of the esophagus are now amenable to improved surgical and gastroenterological therapies; however, they often lead to persistent long-term esophageal dysmotility. Achalasia originates from impaired relaxation of the gastroesophageal sphincter apparatus. Systemic diseases may give rise to secondary disorders of esophageal motility. A number of visceral neuromuscular disorders show an esophageal manifestation but aganglionosis rarely extends into the esophagus. The growing group of myopathies includes metabolic and mitochondrial disorders with increasing levels of genetic characterization and incipient emergence of therapeutic strategies. Esophagitis with an infectious etiology causes severe dysmotility particularly in immunocompromised patients. Immunologically mediated inflammatory processes involving the esophagus are increasingly better understood. Finally, rare tumors and tumor-like lesions may impair esophageal motor function.

    This ongoing column is dedicated to the challenging clinical interface between psychiatry and primary care-two fields that are inexorably linked.Dysthymic disorder is a smoldering mood disturbance characterized by a long duration (at least two years in adults) as well as transient periods of normal mood. The disorder is fairly common in the US general population (3-6%) as well as in primary care (7%) and mental health settings (up to one-third of psychiatric outpatients). While the etiology of dysthymia remains unknown, there appears to be a genetic susceptibility, which may manifest in the presence of various psychosocial stressors. While the Diagnostic and Statistical Manual of Mental Disorders diagnostic criteria are fairly clear, the disorder can be easily under-recognized for a variety of reasons. Treatment may include pharmacotherapy and psychotherapy, although the overall treatment course is oftentimes characterized by protracted symptoms and relapses.

    Full Text Available Abstract Background Thought and language disorders are main features of adults with schizophrenia and bipolar disorders however studies on such abnormalities are scant in young patients with very early onset psychosis (VEOS. The aim of the present study is to assess the relationship between language and thought disorders in patients with very early onset schizophrenia (SCZ, schizoaffective disorders (SCA and bipolar disorders (BD. Method Forty-one patients (18 SCZ, 16 BD, and 7 SCA with mean age less than 15 years old were assessed through a series of neurocognitive and psycholinguistic tests, including the Thought, Language and Communication Scale (TLC. Results SCZ group performed worse in all tests as well as the TLC, followed by SCA and BD groups respectively. Thought disorders were related to deficits in executive functioning and semantic processing, and the metaphors’ test was the best predictor of TLC functioning. Discussion TD in SCZ, SCA and BD are one of the most important features in patients with VEOS and that the evaluation of metaphor comprehension can be an important instrument in the early detection of this disorder.

    Patients with Major Affective Disorder (MAD), Secondary Depression, Panic Disorder, and bulimia with and without MAD, were given the Eating Disorder Inventory, the Beck Depression Inventory, and the General Behavior Inventory at presentation. It was found that patients with MAD have a triad of eating disorder symptoms: a disturbance in interoceptive awareness, the sense of ineffectiveness, and a tendency toward bulimia. The data supported the concept that the sense of ineffectiveness is secon...

    In this paper, it was reviewed neuroimaging results of the pituitary gland in psychiatric disorders, particularly schizophrenia, mood disorders, anxiety disorders, and somatoform disorders. The author made internet search in detail by using PubMed database including the period between 1980 and 2012 October. It was included in the articles in English, Turkish and French languages on pituitary gland in psychiatric disorders through structural or functional neuroimaging results. After searching mentioned in the Methods section in detail, investigations were obtained on pituitary gland neuroimaging in a variety of psychiatric disorders. There have been so limited investigations on pituitary neuroimaging in psychiatric disorders including major psychiatric illnesses like schizophrenia and mood disorders. Current findings are so far from the generalizability of the results. For this reason, it is required to perform much more neuroimaging studies of pituitary gland in all psychiatric disorders to reach the diagnostic importance of measuring it.

    The diagnosis of dysthymic disorder was created in DSM-III and maintained in DSM-IV to describe a depressive syndrome of mild to moderate severity of at least two years' duration that did not meet criteria for major depressive disorder. The prevalence of dysthymic disorder is approximately 2% in the elderly population where subsyndromal depressions of lesser severity are more common. Dysthymic disorder was replaced in DSM-V by the diagnosis of "persistent depressive disorder" that includes chronic major depression and dysthymic disorder. In older adults, epidemiological and clinical evidence supports the use of the term "dysthymic disorder." In contrast to young adults with dysthymic disorder, older adults with dysthymic disorder commonly present with late age of onset, without major depression and other psychiatric disorders, and with a low rate of family history of mood disorders. They often have stressors such as loss of social support and bereavement, and some have cerebrovascular or neurodegenerative pathology. A minority has chronic depression dating from youth with psychiatric comorbidity similar to young adults with dysthymic disorder. In older adults, both dysthymic disorder and subsyndromal depression increase disability and lead to poor medical outcomes. Elderly patients with dysthymic disorder are seen mainly in primary care where identification and treatment are often inadequate. Treatment with antidepressant medication shows marginal superiority over placebo in controlled trials, and problem-solving therapy shows similar efficacy. Combined treatment and collaborative care models show slightly better results, but cost effectiveness is a concern. Further work is needed to clarify optimal approaches to the treatment of dysthymic disorder in elderly patients.

    The co-occurrence of substance use disorders with anxiety disorders and/or posttraumatic stress disorder has been widely documented and when compared to each disorder alone, consistently linked to increased risk for a host of negative outcomes including greater impairment, poorer treatment response, and higher rates of symptom relapse. This article focuses on recent advances in the understanding and effective treatment of this common and highly complex comorbidity. Prevalence and epidemiological data are introduced, followed by a review of contemporary models of etiology and associative pathways. Conceptualizations of effective treatment approaches are discussed alongside evidence from the past decade of clinical research trials. Highlighted are ongoing questions regarding the benefit of sequential, parallel, and integrated approaches and the necessity of further investigation into the mechanisms underlying treatment efficacy. Lastly, recent contributions from neuroscience research are offered as a promising bridge for the development and testing of novel, interdisciplinary treatment approaches.

    Full Text Available Little is known about the etiology of neuropsychiatric disorders. The identification of autoantibodies targeting the N-methyl-d-aspartate receptor (NMDA-R, which causes neurological and psychiatric symptoms, has reinvigorated the hypothesis that other patient subgroups may also suffer from an underlying autoimmune condition. In recent years, a wide range of neuropsychiatric diseases and autoantibodies targeting ion-channels or neuronal receptors including NMDA-R, voltage gated potassium channel complex (VGKC complex, α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPA-R, γ-aminobutyric acid receptor (GABA-R and dopamine receptor (DR were studied and conflicting reports have been published regarding the seroprevalence of these autoantibodies. A clear causative role of autoantibodies on psychiatric symptoms has as yet only been shown for the NMDA-R. Several other autoantibodies have been related to the presence of certain symptoms and antibody effector mechanisms have been proposed. However, extensive clinical studies with large multicenter efforts to standardize diagnostic procedures for autoimmune etiology and animal studies are needed to confirm the pathogenicity of these autoantibodies. In this review, we discuss the current knowledge of neuronal autoantibodies in the major neuropsychiatric disorders: psychotic, major depression, autism spectrum, obsessive-compulsive and attention-deficit/hyperactivity disorders.

    Full Text Available Burning mouth disorder (BMD is a burning or stinging sensation affecting the oral mucosa, lips and/or tongue, in the absence of clinically visible mucosal lesions. There is a strong female predilection, with the age of onset being approximately 50 years. Affected patients often present with multiple oral complaints, including burning, dryness and taste alterations. The causes of BMD are multifactorial and remain poorly understood. Recently, there has been a resurgence of interest in this disorder with the discovery that the pain of burning mouth syndrome (BMS may be neuropathic in origin and originate both centrally and peripherally. The most common sites of burning are the anterior tongue, anterior hard palate and lower lip, but the distribution of oral sites affected does not appear to affect the natural history of the disorder or the response to treatment BMS may persist for many years. This article provides updated information on BMS and presents a new model, based on taste dysfunction, for its pathogenesis.
