    Relapse of acute lymphoblastic leukemia (ALL) may occur in extramedullary sites, mainly central nervous system (CNS) and testis. Optimal post-remissional treatment for isolated extramedullary relapse (IEMR) is still controversial. We collected data of children treated with hematopoietic stem cell transplantation (HSCT) for ALL IEMR from 1990 to 2015 in Italy. Among 281 patients, 167 had a relapse confined to CNS, 73 to testis, 14 to mediastinum, and 27 to other organs. Ninety-seven patients underwent autologous HSCT, 79 received allogeneic HSCT from a matched family donor, 75 from a matched unrelated donor, and 30 from an HLA-haploidentical donor. The 10-year overall survival was 56% and was not influenced by gender, ALL blast immune-phenotype, age, site of relapse, duration of first remission, and type of HSCT. In multivariable analysis, the only prognostic factors were disease status at HSCT and year of transplantation. Patients transplanted in third or subsequent complete remission (CR) had a risk of death 2.3 times greater than those in CR2. Children treated after 2000 had half the risk of death than those treated before that year. Our results suggest that both autologous and allogeneic HSCT may be considered for the treatment of pediatric ALL IEMR after the achievement of CR2.

    Allogeneic stem cell transplantation (SCT) is curative treatment in patients with acute leukemia and myelodysplastic syndrome. However, recurrent disease is the major cause of treatment failure. Isolated extramedullary relapse (iEMR) after SCT is relatively rare and not well characterized. We performed a retrospective analysis of 566 consecutive patients with acute myeloid leukemia (n = 446) and acute lymphoblastic leukemia (ALL; n = 120) after SCT to study the incidence, risk factors, treatment options, and outcome of iEMR. The 5-year cumulative incidence of bone marrow relapse (BMR) and iEMR was 41.0% and 5.8%, respectively. iEMR occurred significantly later than BMR at 10 and 4 months, respectively (P BMR but did not protect against iEMR. Most patients with iEMR received systemic treatment combined with local radiation and donor lymphocyte infusions when feasible. The 3-year survival after relapse was 8.5% and 30.1% after BMR and iEMR, respectively (P = .002). Patients with a first iEMR continued to have recurrent EMRs, and only a minority progressed to BMR. Second iEMR was also common after first BMR and associated with longer survival than second BMR. iEMR is more frequent in patients with ALL and prior extramedullary disease. It occurs later than BMR and more commonly in patients with chronic GVHD, suggesting less effective graft-versus-leukemia effect in extramedullary sites. Second iEMR is common after a first iEMR but also after a first BMR. Long-term survival is feasible with aggressive treatment.

    Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Relapse of ALL occurs in 15%-20% of patients, with 2%-6% occurring exclusively in extramedullary sites. Relapse of ALL in gynecologic organs is extremely rare. We present a case of a 12-year-old girl with a history of ALL who was referred to the pediatric gynecology clinic with abnormal uterine bleeding. She was determined to have an extramedullary uterine relapse of her ALL. Abnormal uterine bleeding in the setting of childhood malignancy is a frequent reason for consultation to pediatric and adolescent gynecology services. This bleeding is commonly attributed to thrombocytopenia due to bone marrow suppressive chemotherapeutic agents. However, as shown in this report, abnormal uterine bleeding might be a manifestation of an extramedullary relapse. Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology.

    The intensive therapy of the Burkitt-All achieved higher remission rates in the last years. Relapses and therapy refractory are a big medial problem. Radiotherapy in contribution with radiosensitizer used by an extramedullary large relapse of Burkitt-All is documented in this article as a successful therapy method. (boteke)

    Extramedullary (EM) relapse of leukemia after allo-SCT in patients with AML/myelodysplastic syndrome has been increasingly reported. The reduced effectiveness of the GVL effect in EM sites, as compared with BM, has been suggested to underlie this problem. We retrospectively analyzed the pattern of relapse after haploidentical SCT (haplo-SCT), performed as the first or second SCT. Among 38 patients who received haplo-SCT as their first SCT, the cumulative incidences of BM and EM relapse at 3 years were 40.5 and 10.9%, respectively. Among 19 patients who received haplo-SCT as their second SCT, the cumulative incidences of BM and EM relapse were 30.9 and 31.9%, respectively. Moreover, most of the patients who underwent repeat haplo-SCT for the treatment of EM relapse had further EM relapse at other sites. Post-relapse survival did not differ significantly with different patterns of relapse. The frequent occurrence of EM relapse after haplo-SCT, particularly when performed as a second SCT, suggests that the potent GVL effect elicited by an HLA disparity also occurs preferentially in BM. Our findings emphasize the need for a treatment strategy for EM relapse that recognizes the reduced susceptibility of EM relapse to the GVL effect.

    Purpose: Approximately 5% to 20% of patients who undergo total body irradiation (TBI) in preparation for hematopoietic cell transplantation (HCT) can develop extramedullary (EM) relapse. Whereas total marrow and lymphoid irradiation (TMLI) provides a more conformally targeted radiation therapy for patients, organ sparing has the potential to place the patient at a higher risk for EM relapse than TBI. This study evaluated EM relapse in patients treated with TMLI at our institution. Methods and Materials: Patients eligible for analysis had been enrolled in 1 of 3 prospective TMLI trials between 2006 and 2012. The TMLI targeted bones, major lymph node chains, liver, spleen, testes, and brain, using image-guided tomotherapy with total dose ranging from 12 to 15 Gy. Results: A total of 101 patients with a median age of 47 years were studied. The median follow-up was 12.8 months. Incidence of EM relapse and bone marrow (BM) relapse were 12.9% and 25.7%, respectively. Of the 13 patients who had EM relapse, 4 also had BM relapse, and 7 had EM disease prior to HCT. There were a total of 19 EM relapse sites as the site of initial recurrence: 11 soft tissue, 6 lymph node, 2 skin. Nine of these sites were within the target region and received ≥12 Gy. Ten initial EM relapse sites were outside of the target region: 5 sites received 10.1 to 11.4 Gy while 5 sites received <10 Gy. Pretransplantation EM was the only significant predictor of subsequent EM relapse. The cumulative incidence of EM relapse was 4% at 1 year and 11.4% at 2 years. Conclusions: EM relapse incidence was as frequent in regions receiving ≥10 Gy as those receiving <10 Gy. EM relapse rates following TMLI that included HCT regimens were comparable to published results with regimens including TBI and suggest that TMLI is not associated with an increased EM relapse risk.

    Extramedullary plasmacytomas constitute a rare and not well studied subset of multiple myeloma (MM) relapses. We report the incidence, clinical-laboratory features and outcome of patients with MM and extramedullary relapse (ExMeR). A total of 303 patients with symptomatic MM were recorded in a 13-year period in two institutions. Twenty-eight cases of ExMeR (9%) were recorded. There was an increased frequency of elevated lactate dehydrogenase (LDH) (p = 0.026), bone plasmacytomas (p = 0.001) and fractures (p = 0.002) at diagnosis, in patients with ExMeR compared to the others. ExMeR was associated with an ominous outcome, high LDH, constitutional symptoms and a statistically significant decrease of monoclonal paraprotein compared to levels at diagnosis (p = 0.009). Prior treatment with bortezomib was associated with a decreased hazard of ExMeR (p = 0.041). Overall survival (OS) was decreased in patients with ExMeR compared to the others (38 vs. 59 months, p = 0.006). Patients with MM with ExMeR have a lower OS and their clinical and laboratory features differ from those without.

    Extramedullary plasmacytomas are rare manifestation of plasma cell malignancies. After hematopoietic stem cell transplantation HSCT, presentation of localized plasmacytoma with extramedullary growth is very unusual. We report a case of a 56-year-old woman with Dune-Salmon stage IIIA immunoglobulin A-kappa multiple myeloma, which presented 120 days after autologous HSCT with extramedullary plasmacytoma arising from a lymph node in supraclavicular region. The patient had no pretransplant-history related with extramedullary disease. There was no increase of plasma cells in bone marrow or monoclonal protein in urine or serum. Aspiration smears of lymph node revealed a population of plasmacytoid cells at various stages of maturation. The patient was successfully treated with local radiotherapy and has remained progression-free for more than 20 months. (author)

    Full Text Available Myeloid sarcoma is a rare tumor consisting of myeloid blasts that involve anatomic sites outside the bone marrow. Fatal prognosis is inevitable in patients with extramedullary relapse after hematopoietic stem cell transplantation (HSCT, and no standard treatments are available yet. We report the first case of extramedullary relapse after HSCT treated with a combination of daunorubicin, cytarabine, and cladribine (DAC regimen plus radiotherapy and donor lymphocyte infusion (DLI. This treatment induced a new and durable remission in our patient. The favorable toxicity profile and the reduced cost make this combination worthy of further investigations.

    2011-11-01

    Plasmacytoma is a tumor mass consisting of atypical plasma cells. Incidence of plasmacytomas associated with multiple myeloma range from 7% to 17% at diagnosis and from 6% to 20% during the course of the disease. In both situations, occurrence of extramedullary disease has been consistently associated with a poorer prognosis of myeloma. Extramedullary relapse or progression occurs in a variety of clinical circumstances and settings, and therefore requires individualization of treatment. Alkylating agents, bortezomib, and immunomodulatory drugs, along with corticoids, have been used to treat extramedullary relapse but, because of the relatively low frequency or detection rate of extramedullary relapse, no efficacy data are available from controlled studies in this setting.

    To evaluate peripheral blood (PB) for minimal residual disease (MRD) assessment in adults with acute lymphoblastic leukaemia (ALL). We analysed 76 matched bone marrow (BM) aspirate and PB specimens independently for the presence of ALL MRD by six-colour flow cytometry (FC). The overall rate of BM MRD-positivity was 24% (18/76) and PB was also MRD-positive in 22% (4/18) of BM-positive cases. We identified two cases with evidence of leukaemic cells in PB at the time of the extramedullary relapse that were interpreted as MRD-negative in BM. The use of PB MRD as a non-invasive method for monitoring of systemic relapse may have added clinical and diagnostic value in patients with high risk of extramedullary disease. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Purpose. - To study the localization, treatment and prognosis of extramedullary plasmocytoma through a series of eight patients and a literature review. Patients and methods. - Eight patients with extramedullary plasmocytoma were treated in the university's hospital of Sfax in Tunisia. The average age was 57.3 years. Female represented 75% of patients. The diagnosis of plasmocytoma was based on anatomo-pathology and immunohistochemistry of a biopsy or resected tumour. Extramedullary location was confirmed if biological and radiological exams and medullary biopsy were normal. The therapeutic decision was made after multidisciplinary meetings regarding tumour location and anterior treatment. Results. - Solitary extramedullary plasmocytoma was located in nasal cavity, cervical node, testis, ovary, bladder and the tongue. One patient was treated for three simultaneous locations of extramedullary plasmocytoma (node, bowel, pleura) without evidence of myeloma. Radiotherapy was proposed in six cases but refused in one case (plasmocytoma of the bladder is currently receiving radiotherapy). Treatment consisted in chemotherapy in two cases. Evaluation after treatment revealed complete remission in 86% of the cases. Nodal recurrence was noted in two cases. These two patients were lost to follow up. The five other patients were in complete remission after a mean follow up of 5.7 years. No local recurrence or myeloma was noted. Conclusion. - Extramedullary plasmocytoma is a rare affection. It can occur in any region of the body. Head and neck is most frequent localization. The treatment is irradiation or surgery in some localization. Progression to myeloma is the most important factor that influences the prognosis of the disease. (authors)

    2018-01-01

    Full Text Available Acute lymphoblastic leukemia is commonly cured when diagnosed in the pediatric population. It portends a poorer prognosis if present in adult patients. Although adults frequently achieve complete remission, relapse rates are substantial, particularly among the elderly and high-risk populations. In the absence of prophylactic intrathecal chemotherapy, more than half of patients may develop CNS involvement or relapse, which is associated with significant risk for systemic illness. This report describes a patient with acute lymphoblastic leukemia with repeated isolated CNS relapses. This case should remind clinicians that isolated CNS disease in the absence of systemic recurrence could successfully respond to intrathecal therapy and offer patients a favorable quality of life.

    Objective: To analyze the clinical feature of extramedullary plasmacytoma (EMP) and treatment results. Methods: From Jan. 1960 to Aug. 2000, 28 EMP patients accumulated in a period of 40 odd years were evaluated retrospectively. Sixteen of them were treated with radiotherapy alone (R group, 57.1%) with a median dose of 50 Gy, 11 with combined modality therapy (CMT group, 39.3%) and 1 with surgery alone (S group, 3.6%). Results: During a median follow-up of 90 months (4-280 months), 2 developed local recurrence and 2 were converted to multiple myeloma. The overall 3-, 5-, and 10-year survival rates were 92.6%, 75.6% and 75.6%, respectively. In the R group, the overall 3-, 5-, and 10-year survival rates were 93.8%, 77.3% and 77.3%, as compared with 90.9%, 72.7% and 72.7% in the CMT group (P>0.05). Conclusions: Extramedullary plasmacytoma may well be cured with small field and limited dose of radiation therapy alone. The diagnosis of extramedullary plasmacytoma requires a complete work-up (including MRI) and strict criteria to exclude multiple myeloma. Close follow-up is necessary in those converted to multiple myeloma. (authors)

    Full text: Extramedullary hematopoiesis arises from pleuripotential stem cells distributed throughout the body. It is most common in patients with congenital hemolytic anemia, such as thalassemia, sickle cell anemia and hereditary spherocytosis as a response to ineffective red blood cell formation. Although microscopic foci of Extramedullary hematopoiesis are commonly seen in the spleen and liver parenchyma, focal mass-like lesion of extramedullary hematopoiesis in the liver and spleen are rare. We report a case of intrasplenic focal extramedullary hematopoiesis lesions and the imaging features of extramedullary hematopoiesis on computed tomography and magnetic resonance imaging. Extramedullary hematopoiesis should always be considered as a diagnosis in a patient with a known hematological disorder

  3. Isolation of Trypanosoma brucei gambiense from cured and relapsed sleeping sickness patients and adaptation to laboratory mice.

    Directory of Open Access Journals (Sweden)

    Patient Pati Pyana

    Full Text Available BACKGROUND: Sleeping sickness due to Trypanosoma brucei (T.b. gambiense is still a major public health problem in some central African countries. Historically, relapse rates around 5% have been observed for treatment with melarsoprol, widely used to treat second stage patients. Later, relapse rates of up to 50% have been recorded in some isolated foci in Angola, Sudan, Uganda and Democratic Republic of the Congo (DRC. Previous investigations are not conclusive on whether decreased sensitivity to melarsoprol is responsible for these high relapse rates. Therefore we aimed to establish a parasite collection isolated from cured as well as from relapsed patients for downstream comparative drug sensitivity profiling. A major constraint for this type of investigation is that T.b. gambiense is particularly difficult to isolate and adapt to classical laboratory rodents. METHODOLOGY/PRINCIPAL FINDINGS: From 360 patients treated in Dipumba hospital, Mbuji-Mayi, D.R. Congo, blood and cerebrospinal fluid (CSF was collected before treatment. From patients relapsing during the 24 months follow-up, the same specimens were collected. Specimens with confirmed parasite presence were frozen in liquid nitrogen in a mixture of Triladyl, egg yolk and phosphate buffered glucose solution. Isolation was achieved by inoculation of the cryopreserved specimens in Grammomys surdaster, Mastomys natalensis and SCID mice. Thus, 85 strains were isolated from blood and CSF of 55 patients. Isolation success was highest in Grammomys surdaster. Forty strains were adapted to mice. From 12 patients, matched strains were isolated before treatment and after relapse. All strains belong to T.b. gambiense type I. CONCLUSIONS AND SIGNIFICANCE: We established a unique collection of T.b. gambiense from cured and relapsed patients, isolated in the same disease focus and within a limited period. This collection is available for genotypic and phenotypic characterisation to investigate the

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

    lntrathoracic extramedullary haematopoiesis is a rare condition. Involvement of the spinal epidural space with haematopoietic tissue is rather unusual. A 31-year-old-man with a known diagnosis of β-thalassaemia was referred with focal back pain. Magnetic resonance imaging revealed diffuse bone-marrow changes, thoracic paraspinal masses and lobulated epidural masses, suggesting extramedullary haemopoiesis. The patient was treated with radiotherapy and blood transfusions. Follow-up MRI was performed for evaluation efficacy of the treatment. Copyright (2002) Blackwell Science Pty Ltd

  8. Prognosis and treatment after relapse of acute lymphoblastic leukemia and non-Hodgkin's lymphoma: 1985. A report from the Childrens Cancer Study Group

    1986-01-01

    Acute lymphoblastic leukemia and non-Hodgkin's lymphoma constitute 42% to 45% of the cancers in infants, children, and adolescents: In 1985, an estimated 2025 children were newly diagnosed with these two cancers and 900 (43%) of the pediatric cancer deaths in the United States have been projected to be due to these diseases. The single most important obstacle to preventing these deaths is relapse, and prevention of relapse or salvage of the patient who has had a relapse continues to be a major therapeutic challenge. The most important initial step in the treatment of the child whose disease has relapsed is to determine, to the extent possible, the prognosis. In a child with non-Hodgkin's lymphoma, a relapse confers an extremely poor prognosis, regardless of site of relapse, tumor histology, or other original prognostic factors, prior therapy, or time to relapse. In the child with acute lymphoblastic leukemia in relapse, the prognosis depends on multiple factors. The primary therapy is chemotherapy or chemoradiotherapy with marrow grafting. Other options exist, including no therapy, or investigational therapy. The therapy selected should be predicated on the prognosis. In the child with an isolated central nervous system (CNS) relapse off therapy, minimum therapy should be administered, particularly if the relapse occurred without prior cranial irradiation. In the child whose relapse is more than 6 months off therapy, conventional therapy should be considered. Also, a patient with an isolated CNS relapse on therapy after prior cranial irradiation should be given moderate therapy. Bone marrow transplantation or high-dose chemoradiotherapy with autologous marrow rescue should be reserved in children with a second or subsequent extramedullary relapse, and possibly for those with a first isolated overt testicular relapse on therapy

    Objective: The purposes of our study were to employ diffusion tensor imaging (DTI)-based histogram analysis to determine the presence of occult damage in clinically isolated syndrome (CIS), to compare its severity with relapsing-remitting multiple sclerosis (RRMS), and to determine correlations between DTI histogram measures and clinical and MRI indices in these two diseases. Materials and methods: DTI scans were performed in 19 CIS and 19 RRMS patients and 19 matched healthy volunteers. Histogram analyses of mean diffusivity and fractional anisotropy were performed in normal-appearing brain tissue (NABT), normal-appearing white matter (NAWM) and gray matter (NAGM). Correlations were analyzed between these measures and expanded disability status scale (EDSS) scores, T 2 WI lesion volumes (LV) and normalized brain tissue volumes (NBTV) in CIS and RRMS patients. Results: Significant differences were found among CIS, RRMS and control groups in the NBTV and most of the DTI histogram measures of the NABT, NAWM and NAGM. In CIS patients, some DTI histogram measures showed significant correlations with LV and NBTV, but none of them with EDSS. In RRMS patients, however, some DTI histogram measures were significantly correlated with LV, NBTV and EDSS. Conclusion: Occult damage occurs in both NAGM and NAWM in CIS, but the severity is milder than that in RRMS. In CIS and RRMS, the occult damage might be related to both T2 lesion load and brain tissue atrophy. Some DTI histogram measures might be useful for assessing the disease progression in RRMS patients

    Extramedullary haemopoiesis (EH) is a compensatory process associated with chronic haemolytic anaemia. It is rare, however, for such an abnormality to cause spinal cord compression. We present two patients with known beta-thalassaemia intermedia who developed spinal cord compression due to masses of extramedullary haematopoietic tissue in the epidural space of the thoracic spine. The EH masses were diagnosed by MRI as an isointense epidural lesion on both T1- and T2-weighted images, compressing severely the spinal cord. After administration of a paramagnetic agent, an intermediate enhancement of the masses was evident. All the vertebral bodies had low to intermediate signal intensity as a result of displacement of fatty marrow by haematopoietic marrow. Expansion of thoracic ribs with bilateral paravertebral masses were characteristic. A small dose of radiotherapy was given and marked improvement in neurological symptoms was evident. An MRI examination established shrinkage of the mass and decompression of spinal cord. The role of MRI in diagnosis of EH masses is essential and radiation therapy is a very effective treatment for this rare complication. (orig.)

    Extramedullary plasmacytoma of the head and neck region (EMPHN) is an uncommon malignant plasma cell neoplasm. In this study we conducted a retrospective analysis of our experience of EMPHN with particular emphasis on the role of definitive radiotherapy. From 1982 to 2001, 10 patients (6 males, 4 females) with EMPHN were treated in our institution. Of nine patients treated at initial diagnosis, all received definitive radiotherapy. One patient treated at relapse underwent surgical resection followed by post-operative radiotherapy. The median age at diagnosis was 55 years (range 35-84 years). The disease was most frequently localized in the paranasal sinuses (50%). All nine patients who received definitive radiotherapy at a dose of 40-50 Gy achieved a complete response. The median follow up period was 29 months (range 7-67 months). Four patients (40%) relapsed, three have died of their disease. Two patients (20%) with paranasal sinus disease subsequently relapsed with multiple myeloma at 10 months and 24 months, respectively. Our results indicate that treatment of EMPHN with radiotherapy achieves excellent rates of local control. The relapse rate in neck nodes of 10% does not justify elective irradiation of the uninvolved neck.

    A 62-year-old man was referred to us after unsuccessful treatment of bilateral weakness in his upper and lower extremities with paresthesia in both lower extremities. Computed tomography (CT) revealed soft tissue masses in the left kidney along the capsule and paraaortic region that were of relatively low attenuation with accompanying granular calcifications. Pathological diagnosis of the biopsy specimen was extramedullary plasmacytoma accompanied by extramedullary hematopoiesis and amyloid deposition. Although the CT findings correlated well with the pathological results, the case was extremely atypical for extramedullary plasmacytoma in respect to location and the accompaniment with extramedullary hematopoiesis.

    Relapses of lymphoblastic leukaemia traditionally involve the central nervous system and testes in boys. Involvement of the female pelvic organs is frequently found at autopsy; however, involvement of the cervical uterus is rare and even less commonly symptomatic. A 13-cm uterine mass was discovered in a 15-year-old adolescent with a history of lymphoblastic leukaemia during childhood. Pelvic MRI was the best tool to assess the size, characteristics and invasive nature of this lesion of the uterine cervix. To our knowledge, this is a unique case in that we describe the MRI appearance of a relapsing lymphoblastic leukaemic mass both before and after treatment. (orig.)

    We present the case of a patient diagnosed with a testicular extramedullary plasmacytoma (EMP), and perform a brief review of the literature of this pathology. A 64 year-old male patient, with history of multiple myeloma successfully treated three years before, presented with left testicular swelling. Initial work-up was compatible with a testicular tumor and radical inguinal orchiectomy was performed. Histologic examination of the testis revealed extensive intertubular infiltration by CD138 and CD56 atypical plasma cells, with diffuse staining for IgA, compatible with EMP. Invasion of the testis in multiple myeloma patients as a recurrence of the disease is an extremely rare condition, as EMPs are more common in other organ systems. Initial treatment should be the same as a primary testicular tumor with radical inguinal orchiectomy, and definitive diagnosis is established in histologic analysis.

    To report the imaging appearances of mass-like extramedullary hematopoiesis (EMH), to identify those features that are sufficiently characteristic to allow a confident diagnosis, and to recognize the clinical conditions associated with EMH and the relative incidence of mass-like disease. We retrospectively identified 44 patients with EMH; 12 of which (27%) had focal mass-like lesions and formed the study group. The study group consisted of 6 male and 6 female subjects with a mean age of 58 years (range 13-80 years). All 12 patients underwent CT imaging and 3 of the 12 patients had undergone additional MR imaging. The imaging characteristics of the extramedullary hematopoiesis lesions in the study group were analyzed and recorded. The patient's clinical presentation, including any condition associated with extramedullary hematopoiesis, was also recorded. Ten of the 12 (83%) patients had one or more masses located along the axial skeleton. Of the 10 patients with axial masses, 9 (90%) had multiple masses and 7 (70%) demonstrated internal fat. Eight patients (80%) had paraspinal masses and 4 patients (40%) had presacral masses. Seven patients (70%) had splenomegaly. Eleven of the 12 patients had a clinical history available for review. A predisposing condition for extramedullary hematopoiesis was present in 10 patients and included various anemias (5 cases; 45%), myelofibrosis/myelodysplastic syndrome (4 cases; 36%), and marrow proliferative disorder (1 case; 9%). One patient had no known predisposing condition. Mass-like extramedullary hematopoiesis most commonly presents as multiple, fat-containing lesions localized to the axial skeleton. When these imaging features are identified, extramedullary hematopoiesis should be strongly considered, particularly when occurring in the setting of a predisposing medical condition. (orig.)

    Less than 10% of the patients with plasma cell neoplasms present with a solitary plasmacytoma. Though the nasal cavity is a common extramedullary site, the occurrence is extremely rare. Two cases of solitary extramedullary plasmacytoma of the sinonasal region are reported. The first of which is sinonasal plasmacytoma with concomitant HIV, an association that has been reported rarely in literature to date and is matter of much debate. In the second case report, we present an instance of surgical excision of the tumor using KTP 532 laser. The diagnosis was established using immunohistochemical techniques and multiple myeloma workups were negative in all cases.

    The prognosis of patients with acute lymphoblastic leukemia (ALL) and central nervous system (CNS) relapse has historically been very poor. Although chemo-radiotherapy has improved outcomes, some patients still have a poor prognosis after CNS relapse. Therefore, allogeneic hematopoietic stem cell transplantation (allo-SCT) has recently become an option for treatment of CNS leukemia; however, information, particularly on the long-term outcome of transplant recipients, is limited. We performed allo-SCT in eight pediatric patients with ALL (n=7) or T-cell type non-Hodgkin's lymphoma (n=1), who had isolated CNS relapse. All patients survived for a median of 70.5 (range, 13-153) months after SCT. Sequelae developed late in some patients: mental retardation (IQ=47) in one patient, severe alopecia in two patients, limited chronic graft-versus-host-disease in three patients, and amenorrhea and/or hypothyroidism in three patients. Except for a pre-school child with post transplant CNS relapse, six out of seven patients show normal school/social performance. Our results clearly indicate a high cure rate of isolated CNS relapse by allo-SCT in pediatric lymphoid malignancies; however, there needs to be further studies to determine which are the appropriate candidates for transplantation and what is the best transplant regimen to achieve high cure rate and maintain good quality of life.

    Plasma cell neoplasms have been classified into various types, with a range of clinical and radiological presentations. Extramedullary plasmacytoma (EMP) is a subset of plasma cell neoplasms which presents as an isolated non-osseous soft tissue mass. Though carotid space neoplasms are commonly encountered, EMP in the carotid space is rare and seldom considered in the initial differential diagnosis of a carotid space mass. These tumors can be treated by surgery or radiotherapy. On the other hand, the commonly encountered tumors in the carotid space are treated surgically. Also, it is mandatory to exclude multiple myeloma in the patients presenting with EMP. Hence, accurate and early diagnosis has therapeutic and prognostic implications. We report a rare case of EMP of the carotid space, describing the imaging features and the differential diagnoses with clues pointing to this rare entity

    Extramedullary plasmacytoma is a rare manifestation of multiple myeloma, and involvement of the mediastinum by extramedullary plasmacytoma is very rare. We report here on a rare case of a large mediastinal extramedullary plasmacytoma and several pleural nodules with pleural effusions in a 45-year-old male patient with multiple myeloma that involved the thoracic spine and the calvarium. The mediastinal extramedullary plasmacytoma manifested on CT as an 11 x 4.5 cm-sized, relatively homogeneous, mildly enhancing, anterior mediastinal mass with several pleural nodules, and this simulated malignant lymphoma or malignant thymic epithelial tumor.

Against this background we studied the relationship between self-efficacy and cognitive performance in the early stages of MS. Thirty-three patients with Clinically Isolated Syndrome (CIS and early Relapsing Remitting MS (eRRMS were assessed for self-efficacy (MSSES-18, cognition (CDR System, fatigue (MFIS-5, depressive symptoms (BDI, disease impact (MSIS-29, and disability (EDSS. Correlative analyses were performed between self-efficacy and cognitive scores, and stepwise regression analyses identified predictors of cognition and self-efficacy. Good correlations existed between total self-efficacy and Power of Attention (r= 0.65; P< 0.001, Reaction Time Variability (r= 0.57; P< 0.001, and Speed of Memory (r= 0.53; P< 0.01, and between control self-efficacy and Reaction Time Variability (r= 0.55; P< 0.01. Total self-efficacy predicted 40% of Power of Attention, 34% of Reaction Time Variability, and 40% of Speed of Memory variabilities. Disease impact predicted 65% of total self-efficacy and 58% of control self-efficacy variabilities. The findings may suggest that in persons with CIS and eRRMS self-efficacy may positively affect cognitive performance and that prevention of disease activity may preserve self-efficacy.

    Renal extramedullary hematopoiesis is rarely recognized in the antemortem setting. We identified 14 patients with renal extramedullary hematopoiesis on antemortem specimens from 1994 to 2015. The mean age was 68 years (range 47-87 years); males predominated (M:F=9:5). All presented with renal insufficiency, including five (36%) with acute kidney injury. The mean serum creatinine at biopsy was 2.9 mg/dl (range 1.2-7.3 mg/dl). All had proteinuria (mean 7.9 g/24 h; range 0.5-28; n=13), including 9 with ≥3 g/24 h. Renal extramedullary hematopoiesis appeared histologically as an interstitial infiltrate (n=12) and/or a perirenal infiltrate (n=3) or mass-like lesion (n=1). Five were misdiagnosed as interstitial nephritis. Concurrent glomerular disease was prevalent and included fibrillary-like glomerulonephritis (n=3), chronic thrombotic microangiopathy (n=5), focal segmental glomerulosclerosis (n=6), and diabetic glomerulosclerosis (n=2). All patients had an underlying hematologic malignancy: primary myelofibrosis in 9, myeloproliferative neoplasm not otherwise specified in 1, essential thrombocythemia in 1, polycythemia vera in 1, and plasma cell myeloma in 2. Clinical follow-up was available in 12 patients, mean of 29 months (range 4-120 months). In 10 patients for whom treatment history could be obtained, 9 were treated with chemotherapy, and 1 was treated with steroids. The mean creatinine at last follow-up was 2 mg/dl (range 1.2-3.9 mg/dl) (n=9). Ten patients died in the follow-up period from their underlying hematological disease and had persistent renal disease. The two remaining patients had persistent chronic kidney disease. Renal extramedullary hematopoiesis should be considered in the differential diagnosis of interstitial infiltrates, particularly in the presence of a glomerulopathy and a hematologic malignancy.

    Granulocytic sarcoma is an extramedullary solid tumour consisting of myelogenous leukaemic blast cells, usually seen in acute myeloid leukaemia and less commonly in patients with chronic myeloid leukaemia or myeloproliferative disorders. Blast cells have a predilection for periosteal and perineural regions and rarely precede evidence of systemic disease. We present two patients, aleukaemic on peripheral blood counts, both at presentation and during subsequent treatment. We present the MRI features of this rare but important condition. (orig.)

    Full Text Available Sleeping sickness caused by Trypanosoma brucei (T.b. gambiense constitutes a serious health problem in sub-Sahara Africa. In some foci, alarmingly high relapse rates were observed in patients treated with melarsoprol, which used to be the first line treatment for patients in the neurological disease stage. Particularly problematic was the situation in Mbuji-Mayi, East Kasai Province in the Democratic Republic of the Congo with a 57% relapse rate compared to a 5% relapse rate in Masi-Manimba, Bandundu Province. The present study aimed at investigating the mechanisms underlying the high relapse rate in Mbuji-Mayi using an extended collection of recently isolated T.b. gambiense strains from Mbuji-Mayi and from Masi-Manimba.Forty five T.b. gambiense strains were used. Forty one were isolated from patients that were cured or relapsed after melarsoprol treatment in Mbuji-Mayi. In vivo drug sensitivity tests provide evidence of reduced melarsoprol sensitivity in these strains. This reduced melarsoprol sensitivity was not attributable to mutations in TbAT1. However, in all these strains, irrespective of the patient treatment outcome, the two aquaglyceroporin (AQP 2 and 3 genes are replaced by chimeric AQP2/3 genes that may be associated with resistance to pentamidine and melarsoprol. The 4 T.b. gambiense strains isolated in Masi-Manimba contain both wild-type AQP2 and a different chimeric AQP2/3. These findings suggest that the reduced in vivo melarsoprol sensitivity of the Mbuji-Mayi strains and the high relapse rates in that sleeping sickness focus are caused by mutations in the AQP2/AQP3 locus and not by mutations in TbAT1.We conclude that mutations in the TbAQP2/3 locus of the local T.b. gambiense strains may explain the high melarsoprol relapse rates in the Mbuji-Mayi focus but other factors must also be involved in the treatment outcome of individual patients.

    A long-term follow-up of a patient with beta thalassaemia with intra- and extraspinal extramedullary haematopoietic tissue compressing the spinal cord is presented. Extramedullary haematopoietic nodules are a rare cause of spinal cord compression and should be included in the differential diagnosis, especially in patients from Mediterranean countries. Treatment with radiation therapy solely failed, giving rise to the need of surgical intervention. Surgical decompression of the spine and the removal of the culprit lesion compressing the spine were performed. Postinterventional radiation therapy was applied to the spine. A relapse had to be treated again by surgical means combined with postinterventional radiation therapy. A complete relief of the symptoms and control of the lesion could be obtained.

    Purpose: A prospective assessment of neurocognitive performance was conducted in children with acute lymphoblastic leukemia (ALL) following isolated central nervous system (CNS) relapse to evaluate the impact of additional systemic/intrathecal (IT) chemotherapy and craniospinal irradiation (CSI) upon long-term intellectual function. Methods and Materials: Twenty-one children with ALL manifesting an isolated CNS relapse between 1984 through 1989 underwent serial evaluations of intellectual function. Neurocognitive function was measured by the full-scale intelligence quotient (FSIQ) as determined by the age-appropriate Wechsler Intelligence Scale and by achievement in reading, math, and spelling as assessed by the Wide Range Achievement Test (WRAT). Intelligence testing was initiated following isolated CNS relapse after clearance of cerebrospinal fluid (CSF) cytology but prior to CSI and continued at annual intervals for a minimum of 4 years postmeningeal failure. Protocol treatment for isolated CNS relapse consisted of reinduction and maintenance systemic therapy, intrathecal (IT) triple-agent chemotherapy, and early CSI (cranium to 24 Gy and spine to 15 Gy at 1.5 Gy/fraction) as outlined on the institutional 'Total XI' trial. Results: All 21 children attained secondary CNS remission and underwent the planned additional systemic/IT chemotherapy and CSI. Fourteen of the 21 children remain in secondary continuous remission, while the remaining 7 experienced a second relapse and were removed from further neurocognitive assessment. For the eight female and six male long-term survivors, mean ages at original diagnosis and at CSI were 5.7 years (range = 0.6-16.2) and 7.0 years (range = 1.8-17.0), respectively. At a median follow-up interval of 4.6 years (ranges 1.7-6.8) post-CNS relapse, comparison of group mean initial to final FSIQs revealed no statistically significant difference between the two measures (94.5 vs. 95.9, respectively, n = 11, p = 0.52).

    Extramedullary hematopoiesis affects about 15% of the patients treated for thalassemia intermedia. Usually seen in adulthood, the most common location is the paraspinal region. Diagnosis and treatment of extramedullary hematopoiesis located in the pelvis of a young 15-year-old girl is discussed. The young age of the patient and the uncommon site of the mass first lead to the diagnosis of an ovarian dermoid cyst. Because of the clinical history and the typical feature on computed tomography scan, extramedullary hematopoiesis was concluded. A specific treatment based on blood transfusion and hydroxyurea was first proposed but remained inefficient. Surgical excision was thus successfully performed. Whereas surgery is limited to spinal cord compression in paraspinal extramedullary hematopoiesis, this observation argues for surgical treatment in symptomatic intraabdominal extramedullary hematopoiesis when medical treatment fails.

    Extramedullary hematopoiesis (EMH) represents tumor-like proliferation of hemopoietic tissue which complicates chronic hemoglobinopathy. Intracranial EMH is an extremely rare occurrence. Magnetic resonance imaging (MRI) offers a precise diagnosis. It is essential to distinguish EMH from other extradural central nervous system tumors, because treatment and prognosis are totally different. Herein, we report the imaging findings of beta-thalassemia in a 13-year-old boy complaining of weakness of left side of the body and gait disturbance; CT and MRI revealed an extradural mass in the right temporoparietal region.

    To determine the role of fine needle aspiration cytology in the diagnosis of extramedullary plasmacytoma. The study group consisted of 13 patients with palpable masses at various sites. The tumors were aspirated for cytologic study. The smears revealed groups of mature and immature plasma cells at various stages of maturation. Mature plasma cells showed an eccentric nucleus and abundant, deep, basophilic cytoplasm with a paranuclear halo. Plasmablasts (immature plasma cells) showed a prominent, eccentric nucleus with single, large nucleolus and abundant, deep, basophilic cytoplasm with no paranuclear halo. Binucleate and multinucleate forms were also seen quite often. The tumors were excised, and the histologic sections confirmed the cytologic diagnosis. All the patients received radiotherapy. One patient (18 years old) developed recurrence and died due to extensive infiltration into the maxilla and mandible. Two patients (57 and 62 years) developed multiple myeloma one to two years after the excision of tumors, and both died two to three months later. The remaining 10 patients were alive and well at this writing. The smears from all 13 patients were diagnosed as extramedullary plasmacytomas by fine needle aspiration cytology.

    Extramedullary hematopoiesis (EMH) is defined as hematopoiesis occurring in organs outside of the bone marrow. The present report describes two cases of thalassemic patients with paraspinal medullary hematopoiesis and analyzes the clinical manifestations, imaging, pathology, diagnosis and treatment of EMH. In addition, a supplementary review of previously published cases is provided along with a review of the related literature. Computed tomography (CT) of the first case revealed multiple paraspinal masses, and the largest was 6.2×8.0 cm in diameter. Likewise, CT of the second patient revealed multiple paraspinal masses in the bottom of the left thoracic cavity, and the largest was measured 10.1×10.5 cm. The two cases underwent surgical biopsy and the findings were compatible with a diagnosis of EMH. In conclusion, EMH is a compatible and rare disease, and should be distinguished from other neoplasms. EMH must considered when masses with characteristic radiologic appearance are detected in patients with thalassemia intermedia.

    Purpose: To review the histories of extramedullary plasmacytoma patients diagnosed in Slovenia between 1969 and 1999, to determine the relationship between radiotherapy (XRT) dose and local tumor control, and to clarify the role of elective nodal XRT and the prognostic value of Bartl's histologic grading criteria (originally devised for multiple myeloma [MM]). Methods and Materials: The database of the Cancer Registry of Slovenia was used for the identification of patients. The inclusion criteria were as follows: bone marrow biopsy showing less than 10% plasma cells, normal skeletal survey, and immunohistochemically determined tumor monoclonality. Simulation/portal films were reviewed to assess the extent of elective nodal XRT. Results: Twenty-six patients with 31 tumors fulfilled the inclusion criteria. In 4 patients, nine metachronously appearing solitary tumors were diagnosed. The head-and-neck region and other body sites were the sites of origin of primary tumors in 84% and 16% of patients, respectively, whereas in the two regions, regional disease was seen in 15% and 60% of patients, respectively. Therapy was as follows: XRT, 12 patients; surgery and postoperative XRT, 15 patients; and surgery, 4 patients. Ultimate local and regional control rates were 90% and 97%, respectively, and MM developed in 2 (8%) patients. The 10-year disease-specific and overall survival rates were 87% and 61%, respectively. The analysis of the dose-effect relationship showed that more conservative treatment is justified: for macroscopic disease, 40-50 Gy (2 Gy/day), adjusted to the bulk of disease; for microscopic disease, 36-40 Gy; after R0 surgery, no XRT is required, but close observation is needed. No attempts should be made to treat uninvolved nodal regions. Using Bartl's histologic grading criteria, trends were detected in patients with higher tumor grades: regional lymph node involvement (p=0.04) and shorter disease-specific survival (p=0.08). Conclusions: Extramedullary

    Full Text Available We present a case of a 59-year-old man who was found to have clusters of hyperchromatic, small, round nucleated cells within a subdural hematoma removed after a skull fracture. Immunohistochemistry study confirmed that the cells were hematopoietic components predominantly composed of normoblasts. In this paper, we describe the clinical and pathological findings. A brief review of published information on extramedullary hematopoiesis in subdural hematoma and the mechanisms of pathogenesis are also discussed. While extramedullary hematopoiesis is seen anecdotally by neuropathologists in chronic subdural hematomas, only a few cases are documented in the literature. Furthermore, extramedullary hematopoiesis in subdural hematoma can pose a diagnostic challenge for general pathologists who encounter subdural hematoma evacuations seldom in their surgical pathology practices.

    Cutaneous extramedullary hematopoiesis is a rare manifestation of chronic myeloproliferative processes, mainly chronic idiopathic myelofibrosis. In adults, it manifests as macules, papules, nodules, and ulcers on the trunk. The lesions usually appear soon after diagnosis and the possibility of a relationship between splenectomy and the appearance of extramedullary foci of hematopoiesis is still debated. Diagnosis is based on histopathology showing an infiltrate with different combinations of myeloid and erythroid cell precursors and megakaryocytes. Symptomatic treatment is provided alongside treatment of the underlying disease. We report a new case associated with chronic idiopathic myelofibrosis in which foci of cutaneous extramedullary hematopoiesis were observed 9 years after initial diagnosis. The lesions were progressive and the patient went on to develop acute myeloid leukemia.

    Purpose. To report three cases of extramedullary plasmacytoma of the larynx treated at the Institute of Oncology in Ljubljana between 1969-1999. Results. All three patients were treated with radiotherapy only, which resulted in permanent local and regional control of 7.8, 4.7 and 3.5 years. The function of the larynx was preserved in all of them. Two patients died, both to the causes other than plasmacytoma. In none of the patients disease progressed to multiple myeloma. Conclusions. Extramedullary plasmacytoma of the larynx is a rare disease, highly curable when radiotherapy is used. Moderate radiation doses and limited fields ensure excellent cosmetic and functional result.

    Plasmacytoma is a frequent complication of multiple myeloma, either at diagnosis or within disease progression. The extramedullary disease confers a poorer prognosis and is biologically distinct with high-risk molecular and histological features, being resistant to conventional treatments. Radiation therapy remains the most effective treatment for extramedullary lesions to achieve local control. There are very limited data from randomized trials regarding the most appropriate systemic treatment. Case reports such as those presented here, as well as retrospective analysis of series, suggest that lenalidomide is an effective agent, in combination with dexamethasone, in this setting. Additional studies are needed to define the proper management of this condition.

    A 10-year-old spayed female mixed-breed dog was examined because of acute inspiratory dyspnea. Radiography and tracheoscopy revealed a discrete, solitary mass originating from the membranous portion of the trachea at the level of the thoracic inlet. Tracheal resection and anastomosis were performed, and on histologic examination of the resected tissue, extramedullary plasmacytoma was diagnosed. Although tracheal tumors are rare in dogs, they should be considered during evaluation of dogs with signs of airway obstruction. Prognosis is excellent for dogs with extramedullary plasmacytoma in which surgical excision is complete.

    Many efforts have been made to detect local relapse (LR) in the follow-up after stereotactic body radiotherapy (SBRT) for non-small-cell lung cancer (NSCLC) although limited data are available on its treatment and prognosis. We aimed to characterize treatment options and clarify long-term outcomes of isolated LR after SBRT for patients with clinical stage I NSCLC. We reviewed our institutional database in search of patients with isolated LR after SBRT for clinical stage I NSCLC at our institution between 1999 and 2013. Patient characteristics were compared with Mann-Whitney U test, χ2 test, or Fisher's exact test as appropriate. Survival outcomes were estimated with Kaplan-Meier method. Potential prognostic factors were investigated using Cox proportional hazard model. Of 308 patients undergoing SBRT for clinical stage I NSCLC, 49 patients were identified to have isolated LR. Twelve patients underwent salvage surgery, none underwent radiotherapy, and eight patients received chemotherapy, whereas 29 patients received best supportive care. No patient characteristic except operability was significantly related with patient selection for LR treatments. Five-year overall survival (OS) rate of the whole cohort was 47.9% from SBRT and 25.7% from LR. Salvage surgery was associated with improved OS after LR (p = 0.014), and 5-year OS for patients undergoing salvage surgery was 79.5% from LR. It was confirmed that our patient selection for salvage surgery for isolated LR was associated with favorable survival outcomes. Operability based on multidisciplinary conferences, rather than measurable patient characteristics, is essential for appropriate patient selection for salvage surgery.

    Ectopic bone marrow production, known as extramedullary hematopoiesis, may result in symptoms due to compression on normal structures. We present the multimodality imaging findings and subsequent management of a rare case of symptomatic extramedullary hematopoiesis within the calvarium. Case report. A 54-year-old male with a history of myelofibrosis and no previous diagnosis of a headache disorder presented to the emergency department with worsening severe bilateral headaches. A nonenhanced CT of the brain was performed and diffuse extra-axial nodular hyperdensities were visualized. MRI of the brain demonstrated diffuse extra-axial avidly enhancing nodular masses, dural thickening and marked susceptibility. No paravertebral masses, typical for extramedullary hematopoiesis, were present in the chest or abdomen. Although the clinical team considered a biopsy to confirm the diagnosis, we suggested a noninvasive confirmatory test. The subsequent Tc99m sulfur colloid scan corroborated the diagnosis. The patient was then referred to radiation oncology for treatment. In summary, extramedullary hematopoiesis is a hematologic compensatory disorder that rarely occurs within the CNS and may cause neurological compromise due to compression on underlying structures. The diagnosis can be made with noninvasive imaging and treated with low dose radiation therapy. Copyright © 2013 by the American Society of Neuroimaging.

    The role of cognitive domain dysfunction with respect to vocational changes in persons with Clinically Isolated Syndrome (CIS) and early Relapsing Remitting Multiple Sclerosis (eRRMS) is insufficiently known. We investigated thirty-three patients--14 CIS, 19 eRRMS -, mean (standard deviation [SD]) time since diagnosis 13.5 (4.8) months and mean (SD) Expanded Disability Status Scale (EDSS) score 1.3 (1.1). Patients were assessed on the CDR System, a set of automated tests of cognitive function, which yielded scores for Power of Attention (ms), Continuity of Attention (#), Working Memory (SI), Episodic Memory (#) and Speed of Memory (ms). Work-related items and the confounding variables fatigue, depression, disease impact and self-efficacy, were assessed by self-report questionnaires. Patients had poorer Power of Attention compared to normative data (1187 [161.5] vs. 1070 [98.6]; PMemory (4043 [830.6]) vs. 2937 [586.1]; PAttention (Pearson r =  -0.42; PMemory (r = 0.42; PAttention (1247 vs. 1116 ms; PMemory (1.35 vs. 1.57; pAttention and Speed of Memory are reduced, that Power of Attention and Memory are associated with a capability of working less hours, and that fatigue, depression and disease impact may negatively, and self-efficacy positively affect working hours.

    Extramedullary leukaemic disease (EMD, synonym chloroma) is a rare solid manifestation of myeloid leukaemia for which the value of radiotherapy (RT) as a treatment strategy remains controversial. The aim of this study is to analyse the effectiveness of various RT doses for EMD in the modern treatment era. Between January 2000 and June 2016, 20 patients with total of 45 lesions underwent RT for EMD at our institution. With a median radiation dose of 26 Gy (range 4-42 Gy), local remission could be achieved in 91% of patients (complete remission rate: 71%). The median duration of local control (DOLC) was 17 months (95% confidence interval [CI] 0.5-33) and the median overall survival (OS) after chloroma onset was 24 months (95% CI 11-38). No noticeable difference between high- and low-dose regimens has been observed (74% versus 68%; P = 0.5). In the multivariate analysis, only Eastern Cooperative Oncology Group (ECOG) score and bone marrow state during RT have proven to be determinant for durable local control and OS. Low-dose RT (≤26 Gy) achieves good local control compared to high-dose regimes. Bone marrow state during RT and ECOG score during RT may play a crucial role, influencing both DOLC and OS. (orig.)

    The category of extramedullary intradural tumors includes a variety of lesions ranging from meningiomas originating from meningeal cells and nerve sheath tumors (neurofibromas, schwannomas) to less common primary tumors, such as lipomas, ependymomas, hemangiopericytomas, epidermoid cysts and dermoid cysts. Extramedullary metastases can occur as transcoelomic metastases in tumors of the central nervous system (CNS) or metastasization from other tumors. Magnetic resonance imaging (MRI) is the method of choice for localization and characterization of these lesions before treatment. (orig.)

    The main skeletal abnormalities in β-thalassemia are widening of medullary spaces, rarefaction of bone trabeculae, thinning of cortical bone, and perpendicular periosteal spiculation. Premature epiphyseal fusion (PEF) and extramedullary hematopoiesis (EH) are found, though more rarely. The incidence of PEF and EH in 64 patients affected by β-thalassemia is reported. The different incidence of such complications in thalassemia major and intermedia is reported, and a possible correlation with transfusion regimen is also considered. (orig.)

    Extramedullary plasmacytoma involving the penis is extremely rare. Here, we describe a case of primary extramedullary plasmacytoma of the penis in a 64-year-old man who presented with a palpable penile mass. Nuclear magnetic resonance imaging revealed the presence of a large, round non-encapsulated mass in the perineum. A contrast-enhanced computed tomography scan of the pelvis showed that the mass was located in the tunica albuginea and corpora cavernosa at the base of the penis. The mass encased the urethra and demonstrated no marked enhancement during the arterial phase. The patient underwent successful surgical resection of the tumor. Histologically, the tumor was composed primarily of neoplastic plasma cells that were positive for CD38, vimentin and Ki 67. Postoperatively, the patient recovered well and exhibited no evidence of development of multiple myeloma, local recurrence or distant metastasis at 2 months post-surgery. To the best of our knowledge, our case represents the first documented case of human primary extramedullary plasmacytoma of the penis.

    Background: Extramedullary hematopoiesis (EMH) occurs in many disorders, including thalassemias and other hemoglobinopathies, and commonly presents in the spleen and liver. We present a case of spinal cord compression in a patient with beta-thalassemia intermedia, and review the literature and available treatment options. Patient and Methods: A 35-year-old black female with beta-thalassemia intermedia presented with a 3-week history of back pain and lower extremity weakness. Neurologic examination was consistent with spinal cord compression, and gadolinium enhanced magnetic resonance imaging (MRI) confirmed this diagnosis. She was given intravenous steroids and radiotherapy was begun in 200 cGy fractions to a total dose of 2000 cGy. Results: At the completion of radiotherapy the patient was ambulatory with mild residual weakness. MRI scans 16 months later showed smaller, but persistent masses, and she remains asymptomatic 5 years from her diagnosis. Conclusion: Recognition of spinal cord EMH requires prompt physical examination and MRI for accurate diagnosis. EMH can be managed with radiation, surgery, transfusions, or a combination of these therapies. Radiation in conservative doses of (750-3500 cGy) is non-invasive, avoids the surgical risks of potentially severe hemorrhage and incomplete resection, and has a high complete remission rate in the majority of patients. Relapse rates are moderate (37.5%), but retreatment provides excellent chance for second remission

    Spinal epidural extramedullary haematopoiesis is very rare in thalassaemia. A 27-year-old man with thalassaemia intermedia presented with symptoms and signs of spinal cord compression. MRI showed a thoracic spinal epidural mass, representing extramedullary haematopoietic tissue, compressing the spinal cord. Following radiotherapy, serial MRI revealed regression of the epidural mass and gradual resolution of spinal cord oedema. (orig.)

    OBJECTIVE: We report an extremely rare case of extramedullary plasmacytoma. METHOD: Case report and review of the English-literature concerning extramedullary plasmacytoma and multiple myeloma. RESULT: We present an unusual case of multiple extramedullary plasmacytomas, which, over a protracted course of 30 years, presented on different occasions at three separate sites in the head and neck. The patient was managed surgically on all occasions, and was disease-free at the time of writing. CONCLUSION: Following review of the literature, we believe this to be the only case with this extremely unusual presentation. This case is noteworthy, not only because of the rarity of extramedullary plasmacytoma, but also because it highlights a number of important clinical issues. The diagnosis and management of extramedullary plasmacytoma require close cooperation between multiple disciplines.

    Full Text Available Myeloid sarcoma (MS, granulocytic sarcoma or chloroma, is defined as a localized extramedullary mass of blasts of granulocytic lineage with or without maturation, occurring outside the bone marrow. MS can be diagnosed concurrently with acute myeloid leukemia (AML or myelodysplastic syndrome (MDS. The authors report a case of sacral MS occurring as a relapse of myeloid leukemia in a 5-year-old girl who was taken to the emergency department with radiculopathy symptoms.

    The purpose of this study is to report the results of megavoltage irradiation with cobalt-60 in 23 previously unreported cases of extramedullary plasmacytoma of the head and neck. It has been found that 3500 cGy (rad) in three weeks provides good local control of disease with minimal morbidity and a significant proportion do not go on to multiple myeloma. Prognostic factors of significance with respect to subsequent development of multiple myeloma include site and presence or absence of bone destruction. The presence or absence of an M protein peak appears to be of no significance. (author)

    An 11-year-old spayed female Siberian Husky was evaluated because of a 2-week history of progressive paraparesis. Results of neurologic examination were consistent with a T3-L3 myelopathy. There were no abnormalities on CBC, and hypercalcemia was noted on serum biochemical analysis. Several hypoechoic splenic nodules were evident on abdominal ultrasonography, and results of fine-needle aspiration cytology were consistent with splenic extramedullary hematopoiesis (EMH). Two compressive, extradural masses in the dorsal epidural space of the thoracolumbar region of the spinal cord were seen on MRI images. A dorsal laminectomy was performed to remove the extradural spinal masses. Results of histologic examination of tissue samples were consistent with EMH. Following surgery, clinical signs of paraparesis resolved, and there was no recurrence of the masses 24 months after surgery. Extramedullary hematopoesis should be considered as a differential diagnosis in dogs in which results of diagnostic imaging indicate a epidural mass. In human patients, spinal EMH usually occurs secondary to an underlying hematologic disease, but it can also occur spontaneously. Treatment options reported for humans include surgical decompression, radiation therapy, chemotherapy, and blood transfusion. The dog of this report responded favorably to surgical decompression and was clinically normal 2 years after surgery.

    Multiple myeloma is a common hematological malignancy. Aggressive myeloma invades the organs outside the bone marrow, lymph, or reticuloendothelial systems. Among the extramedullary involvements of multiple myeloma, myelomatous ascites are extremely rare and are associated with a poor prognosis. We describe a case of myelomatous ascites as an initial manifestation of extramedullary involvement of multiple myeloma in 39-year-old patient. The patient was treated with high-dose chemotherapy, but extensive extramedullary involvement progressed, and the patient expired approximately five months after the initial detection of ascites.

    Extramedullary plasmacytoma is a rare disease that is histopathologically defined as a solitary tumor composed of a monoclonal proliferation of cells with plasmacytic differentiation in an extramedullary site. Most of these tumors occur in the submucosa of the upper aerodigestive tract, and they rarely occur in the small bowel mesentery. We report here on a case of extramedullary plasmacytoma of the small bowel mesentery that was in association with a cecal cancer. Abdominal ultrasound and CT revealed a lobulated soft tissue mass with a cystic portion and peripheral calcification. In this case, the preoperative radiological diagnosis was difficult due to accompanying cecal cancer

    Full Text Available Tumors of the craniovertebral junction (CVJ pose significant challenges to cranial and spine surgeons. Familiarity with the complex anatomy and avoidance of injury to neurologic and vascular structures are essential to success. Multiple surgical approaches to address lesions at the CVJ have been promoted, including ventral and dorsal-based trajectories. However, optimal selection of the surgical vector to manage the pathology requires a firm understanding of the limitations and advantages of each approach. The selection of the best surgical trajectory must include several factors, such as obtaining the optimal exposure of the region of interest, avoiding injury to critical neurologic or vascular structures, identification of normal anatomical landmarks, the familiarity and comfort level of the surgeon to the approach, and the need for fixation. This review article focuses on dorsal approaches to the CVJ and the advantages and limitations in managing intradural extramedullary tumors.

    Extramedullary hematopoiesis (EMH) is a systemic reaction to inadequate hematopoiesis. We report two exceedingly rare cases of EMH involving the paranasal sinuses. The first patient, a 30-year-old man, presented with a maxillary sinus mass. The lesion was excised by endoscopic surgery: definitive histology identified foci of EMH within an inflammatory fibromyxoid pseudotumor. The second case occurred in a 29-year-old man affected by intermediate beta-thalassemia. He was hospitalized with a diagnosis of sphenoid sinus mucocele secondary to an ethmoid lesion. The patient underwent endoscopic excision of the mass and drainage of the sphenoid mucocele. At definitive histology, a diagnosis of EMH was established. Herein, the presenting modalities, imaging profile, and treatment options of this rare EMH localization are reviewed. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

    2010-06-01

    Ineffective erythropoiesis in patients with thalassemia intermedia drives extramedullary hematopoietic tumor formation in several parts of the body. Paraspinal involvement has received increasing attention due to the associated morbidity secondary to spinal cord compression. Although the history and physical examination may help narrow the differential diagnosis, radiographic imaging remains essential to confirm the existence of hematopoietic tissue. Characteristic appearance has been observed mainly on magnetic resonance imaging. Several treatment options have been described, including transfusion therapy, laminectomy, radiotherapy, and the use of fetal hemoglobin inducing agents that decrease the hematopoietic drive. However, the ideal management scheme remains controversial. Until large prospective trials evaluate the efficacy and safety of the available treatment options, both in single and in combination therapy, an individualized approach should be entertained.

    Spinal teratomas are extremely rare; they constitute meningitis. A 7-year-old boy presented with paroxysmal abdominal pain and a history of recurrent aseptic meningitis. Kernig and Brudzinski signs were present. Lumber puncture revealed pleocytosis with no evidence of bacteria growth. Imaging of the spine revealed a cystic lesion in spinal cord at thoracic level 9-11. Endoscopic excision of the cyst was successfully performed. Surgical and histopathological findings confirmed extramedullary matured teratoma. As the symptomatic attacks of spontaneous rupture of spinal teratoma resemble presentations of Mollaret meningitis, spinal teratoma should be considered in the differential diagnosis of Mollaret meningitis. We describe a rare example of spinal teratoma causing recurrent meningitis. Spine imaging should be considered in individuals with recurrent aseptic meningitis as this promotes earlier diagnosis, more appropriate treatment, and improved neurological outcome.

    Full Text Available A neurenteric cyst of the craniocervical (CV junction, as a cause of bulbomedullary compression, is very rare. An abnormal communication between the endoderm and neuroectoderm during the third week of embryogenesis may be responsible for its formation. It is a rare spinal condition. The most frequent location is at the lower cervical and higher thoracic spine. Neurenteric cysts of the craniocervical junction are even rarer. We report the case of a CV junction intradural neurenteric cyst. Magnetic Resonance Imaging (MRI of our patient demonstrated an intradural extramedullary process of the craniocervical junction. A surgical posterior approach allowed gross total resection of the lesion. The histopathology of the surgical specimen showed that the cyst wall was made up of fibrocollagen walls lined with a partially ciliated columnar epithelium.

    Full Text Available Abstract Background In a standard total knee replacement, tibial component alignment is a key factor for the long term success of the surgery. The purpose of this study is to compare the accuracy of extramedullary and intramedullary tibial cutting guides used in indigenous and imported implants respectively, in positioning of the tibial components in megaprosthetic knee replacements. Methods A comparative study of the accuracy of extramedullary and intramedullary tibial cutting guides was carried out in 92 megaprosthetic knee replacements for distal femoral tumors. For the proximal tibia cut for tibial component placement, an extramedullary guide was used in 65 patients and an intramedullary guide was used in 27 patients. Tibial component alignment angles were measured in postoperative X-rays with the help of CAD software. Results There was more varus placement in coronal plane with extramedullary cutting guide (−1.18 +/− 2.4 degrees than the intramedullary guide (−0.34 +/− 2.31 degrees but this did not reach statistical significance. The goal of 90 +/− 2 degrees alignment of tibial component was achieved in 54% of patients in the extramedullary group versus 67% in the intramedullary group. In terms of sagittal plane alignment, extramedullary guide showed less accurate results (2.09 +/− 2.4 degrees than intramedullary guide (0.50 +/− 3.80 degrees for tibial component alignment, though 78% of patients were aligned within the goal of 0–5 degrees of tibial slope angle in extramedullary group versus 63% in intramedullary group. The mean error in the measurements due to rotation of the knee during taking the X-rays was less than 0.1 degrees and distribution of the X-rays with the rotation of knee was similar in both the groups. Conclusions Overall, in megaprosthetic knee replacement intramedullary guides gave more accurate results in sagittal plane and exhibited similar variability as of extramedullary guides in coronal plane.

    2012-01-01

    Full Text Available Background. Extramedullary hematopoiesis is most often seen in reticuloendothelial organs specially spleen, liver, or lymph nodes, and it is rarely seen in lung parenchyma. Almost all reported cases of pulmonary extramedullary hematopoiesis occurred following myeloproliferative disorders specially myelofibrosis. Other less common underlying causes are thalassemia syndromes and other hemoglobinopathies. There was not any reported case of pulmonary extramedullary hematopoiesis in asthmatic patients in the medical literature. Case. Here we reported a 65-year-old lady who was a known case of bronchial asthma with recent developed right lower lobe lung mass. Chest X-ray and CT studies showed an infiltrating mass resembling malignancy. Fine needle aspiration cytology of mass revealed pulmonary extramedullary hematopoiesis. The patient followed for 10 months with serial physical examination and laboratory evaluations which were unremarkable. Conclusion. Extramedullary hematopoiesis of lung parenchyma can be mistaken for lung cancer radiologically. Although previous reported cases occurred with myelofibrosis or hemoglobinopathies, we are reporting the first case of asthma-associated extramedullary hematopoiesis.

    Extramedullary hematopoiesis (EMH) refers to hematopoiesis outside of the medulla of the bone. Chronic anemia states such as thalassemia can cause hematopoietic tissue to expand in certain locations. We report a case of spinal cord compression due to recurrent spinal epidural EMH, which was treated with a combination of surgery and radiotherapy. Pakistan has one of the highest incidence and prevalence of thalassemia in the world. We describe published literature on diagnosis and management of such cases. An 18-year-old male presented with bilateral lower limb paresis. He was a known case of homozygous beta thalassemia major. He had undergone surgery for spinal cord compression due to EMH 4 months prior to presentation. Symptom resolution was followed by deterioration 5 days later. He was operated again at our hospital with complete resection of the mass. He underwent local radiotherapy to prevent recurrence. At 2 years follow-up, he showed complete resolution of symptoms. Follow-up imaging demonstrated no residual mass. The possibility of EMH should be considered in every patient with ineffective erythropoiesis as a cause of spinal cord compression. Treatment of such cases is usually done with blood transfusions, which can reduce the hematopoietic drive for EMH. Other options include surgery, hydroxyurea, radiotherapy, or a combination of these on a case to case basis.

    Purpose: To define the effectiveness of radiotherapy in the treatment of patients with extramedullary plasmacytoma of the head and neck (EMPHN). Methods and Materials: We searched the Mayo Clinic Rochester Department of Radiation Oncology electronic Tumor Registry and identified 18 consecutive patients with a diagnosis of solitary EMPHN. Sixteen patients were treated with radiotherapy at initial diagnosis and 2 received salvage radiotherapy for local failure after surgery. Median dose administered was 50.4 Gy. Median follow-up was 6.8 years. Results: One patient (6%) developed a marginal recurrence 12 months after treatment. Six patients (33%) developed multiple myeloma (2 patients) or plasmacytomas at distant sites (4 patients) at a median of 3.1 years after diagnosis (range, 0.02 to 9.6 years). Median and 5- and 10-year overall survival rates from the date of diagnosis are 12.5 years, 88%, and 55%, respectively. Two patients (11%) developed a radiation-induced malignancy at 6.5 and 6.9 years after treatment. Conclusions: Radiotherapy provides excellent local and regional tumor control and survival in patients with EMPHN. To the best of our knowledge, this is the first report of presumed radiation-induced malignancy in this patient population

    Relapse after a first episode of schizophrenia is the recurrence of acute symptoms after a period of partial or complete remission. Due to its variable aspects, there is no operational definition of relapse able to modelise the outcome of schizophrenia and measure how the treatment modifies the disease. Follow-up studies based on proxys such as hospital admission revealed that 7 of 10 patients relapsed after a first episode of schizophrenia. The effectiveness of antipsychotic medications on relapse prevention has been widely demonstrated. Recent studies claim for the advantages of atypical over first generation antipsychotic medication. Non-adherence to antipsychotic represents with addictions the main causes of relapse long before some non-consensual factors such as premorbid functioning, duration of untreated psychosis and associated personality disorders. The consequences of relapse are multiple, psychological, biological and social. Pharmaco-clinical studies have demonstrated that the treatment response decreases with each relapse. Relapse, even the first one, will contribute to worsen the outcome of the disease and reduce the capacity in general functionning. Accepting the idea of continuing treatment is a complex decision in which the psychiatrist plays a central role besides patients and their families. The development of integrated actions on modifiable risk factors such as psychosocial support, addictive comorbidities, access to care and the therapeutic alliance should be promoted. Relapse prevention is a major goal of the treatment of first-episode schizophrenia. It is based on adherence to the maintenance treatment, identification of prodromes, family active information and patient therapeutical education. Copyright © 2013 L’Encéphale.

    Full Text Available Abstract Background Extramedullary plasmacytomas are seldom solitary and usually progress to diffuse myelomatosis. Plasmacytomas of the breast are rare, especially when not associated multiple myeloma. Synchronous infiltrating ductal carcinoma and primary extramedullary plasmacytoma of the breast have not previously reported. Case presentation A 27-years-old woman with an untreated upper outer quadrant breast mass for 1-year was referred to our cancer hospital for surgical evaluation of increasing breast pain. Postoperatively, microscopic examination revealed an infiltrating ductal carcinoma complicated by an extramedullary plasmacytoma divided by fibrous tissue in one section. Following surgery, the patient received chemotherapy for the carcinoma and radiotherapy for the plasmacytoma. Conclusion In this case, careful histopathology examination was essential to make the correct diagnosis and therapy for these synchronous lesions. The patient finished chemotherapy and radiotherapy without significant adverse effects.

    Full Text Available ABSTRACT: Extramedullary plasmacytomas (EPs are responsible for 2.5% of neoplasms in dogs. They are solitary, smooth, elevated, pink or red nodules, of 1 to 2cm in diameter. Cutaneous and oral extramedullary plasmacytomas in dogs are usually benign tumors, treated with local therapies. Prognosis is generally good. Recurrence and metastatic rates are low. Electrochemotherapy is a local treatment that combines chemotherapy and electroporation and shows objective responses of 70% to 94% with few local and systemic side effects. This scientific communication has the objective to report treatment of three canine patients with oral extramedullary plasmacytoma. Nodules were located on the tongue and patients were submitted to one or two electrochemotherapy sessions, which preserved the tongue without mutilation and cured the patients.

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

    2014-11-01

    Full Text Available Chronic myelogenous leukemia (CML is a myeloproliferative disorder that normally presents in middle-aged adults. Renal infiltration and extramedullary hematopoiesis in renal tissue has been rarely reported. This case report presents a patient with CML and renal insufficiency who developed gross hematuria. Efforts at controlling the hematuria led to a cascade of events propelled by the underlying disorder that ultimately led to a radical nephrectomy, multiorgan failure, and prolonged hospitalization. We suggest that management of gross hematuria in clinically stable patients with CML, suspected of having extramedullary hematopoiesis, should prioritize treatment of the myeloproliferative disorder over efforts to control bleeding.

Efforts at controlling the hematuria led to a cascade of events propelled by the underlying disorder that ultimately led to a radical nephrectomy, multiorgan failure, and prolonged hospitalization. We suggest that management of gross hematuria in clinically stable patients with CML, suspected of having extramedullary hematopoiesis, should prioritize treatment of the myeloproliferative disorder over efforts to control bleeding.

    Although generally not applied as first-line treatment of multiple myeloma, allogeneic hematopoietic cell transplantation (allo-SCT) can still be chosen as ultimate escalation approach in high-risk patients, preferentially within the framework of clinical trials. In this study, we investigated whether decreasing donor chimerism (DC) is predictive for relapse. In addition, we comprehensively determined the impact of several other disease- and treatment-related factors on outcome. One hundred fifty-five multiple myeloma patients whose DC status was followed serially by the short tandem repeat-based techniques at a single lab were included in this retrospective study. Outcome variables were studied in univariate and multivariable analyses. Available were 2.324 DC samples (median, 12 per patient). Loss of full DC was associated with shorter progression-free survival (PFS) (HR, 1.7; 95% CI, 1.1 to 2.6) but did not impact overall survival. Two-thirds of patients with International Myeloma Working Group-defined relapses still displayed a full DC in peripheral blood or bone marrow. Extramedullary manifestations were observed in 33% of patients, accounting for the discrepancy between DC analysis and the actual disease status. In multivariable analysis, the 2 most relevant variables for an unfavorable PFS were progressive disease before allo-SCT (HR, 3.0; 95% CI, 1.5 to 5.9) and allo-SCT at least the second relapse (HR, 2.8; 95% CI, 1.5 to 4.9), whereas for overall survival progressive disease or partial response before allo-SCT had the strongest negative effects (HR, 4.2; 95% CI, 1.9 to 9, and HR, 2.0; 95% CI, 1.0 to 3.8, respectively). Adverse cytogenetics such as del17p, t(4,14) or amp(1q21) were not associated with shorter survival after allo-SCT. Extensive DC sampling beyond robust engraftment does not appear to provide additional information helpful for disease management in most patients and is challenged by a significant incidence of extramedullary disease.

    Full Text Available Introduction: Primary myelofibrosis (MF is a myeloproliferative neoplasm that results in debilitating constitutional symptoms, splenomegaly, and cytopenias. In patients with symptomatic splenomegaly, splenectomy remains a viable treatment option for MF patients with medically refractory symptomatic splenomegaly that precludes the use of ruxolitinib. Case presentation: We present the clinical case of a patient who was admitted to our Department to perform a splenectomy in MF as a therapeutic step prior to an allogeneic stem cell transplantation (ASCT. A laparotomic splenectomy and excision of whitish wide-spread peritoneal and omental nodulations was performed. There were no operative complications and the surgery was completed with minimal blood loss. The histopathological exam revealed an extramedullary hematopoiesis in both spleen and peritoneal nodules. Conclusion: In primary myelofibrosis it must always be kept in mind the possible presence of peritoneal implants of extramedullary hematopoiesis and ascites of reactive genesis. We report a rare case of peritoneal carcinomatosis-like implants of extramedullary hematopoiesis found at splenectomy for MF.

    Abstract Background Long term survivorship in total knee arthroplasty is significantly dependant on prosthesis alignment. Our aim was determine which alignment guide was more accurate in positioning of the tibial component in total knee arthroplasty. We also aimed to assess whether there was any difference in short term patient outcome. Method A comparison of intramedullary versus extramedullary alignment jig was performed. Radiological alignment of tibial components and patient outcomes of 103 Triathlon total knee arthroplasties were analysed. Results Use of the intramedullary was found to be significantly more accurate in determining coronal alignment (p = 0.02) while use of the extramedullary jig was found to give more accurate results in sagittal alignment (p = 0.04). There was no significant difference in WOMAC or SF-36 at six months. Conclusion Use of an intramedullary jig is preferable for positioning of the tibial component using this knee system.

    Extramedullary hematopoiesis (EMH) occasionally occurs in patients exhibiting hematological disorders with decreased hematopoietic efficacy. EMH is rarely observed in the spinal epidural space and patients are usually asymptomatic. In particular, in the patients with polycythemia vera, spinal cord compression due to EMH is extremely rare. We report a case of polycythemia vera, in which operative therapy proved to be an effective treatment for myelopathy caused by spinal EMH.

    Excessive ineffective erythropoiesis in thalassemia intermedia may cause paravertebral pseudotumors of extramedullary hematopoiesis. Due to the proximity to the spinal canal, these paravertebral masses carry the risk of severe neurological damage. Treatment strategies include hypertransfusion, radiotherapy, and laminectomy. Hydroxyurea, stimulating fetal hemoglobin synthesis, may represent an alternative therapeutic approach. We report on a 26-year-old patient suffering from thalassemia intermedia with progressive anemia symptoms and presenting multiple intrathoracic paravertebral pseudotumors of extramedullary hematopoiesis. Hypertransfusion therapy and splenectomy were followed by regular transfusion (baseline hemoglobin 10 g/dl) and chelation with desferrioxamine. With this treatment, clinical symptoms disappeared, paravertebral hematopoietic masses did not progress, but severe hemosiderosis developed within a few years. Hydroxyurea therapy was initiated to increase the efficacy of erythropoiesis, thereby reducing the required transfusion volume but suppressing concomitantly further expansion of extramedullary hematopoiesis, and finally leading to a reduction of transfusional iron load. Treatment was started with 4 mg/kg per day and stepwise increased to 12.5 mg/kg per day. The fetal hemoglobin concentration increased from 4.5 to 5.5 g/dl after 1 year and to 9.9 g/dl after 2 years of treatment. The yearly transfusion volume was halved during the 1st year of treatment. At present, after 26 months of treatment, the patient has been transfusion-independent for 10 months. Serum ferritin levels decreased from 2844 to 1335 ng/ml. Size and shape of paravertebral hematopoietic pseudotumors remained stable. No side effects of hydroxyurea have been observed. In thalassemia intermedia patients with extramedullary hematopoiesis, hydroxyurea may lead to independence from regular transfusion therapy without further expansion of ectopic hematopoietic tissue.

    Extramedullary haematopoiesis is sometimes encountered in serve anaemia. Rarely, it may cause neurological symptoms, leading to spinal cord or cauda equina compression. Three patients with thalassaemia intermedia, who developed neurological complications, are described. The diagnoses were based on the clinical findings, computed tomography and magnetic resonance imaging. Small doses of radiotherapy (10-20 Gy in 5-10 fractions) relieved symptoms in all of these patients. Our experience supports the role of radiation therapy as a treatment for this complication.

    Extramedullary hematopoiesis (EMH) is a pathological process secondary to underlying bone marrow (BM) insufficiency in adults. It is characterized by the emergence of multipotent hematopoietic progenitors scattered around the affected tissue, most likely in the spleen, liver, and lymph node, etc. EMH in patients frequently receives less medical attention and is neglected unless a compressive or obstructive hematopoietic mass appears to endanger the patient's life. However, on a biological basis, EMH reflects the alteration of relationships among hematopoietic stem and progenitor cells (HSPCs) and their original and new microenvironments. The ability of hematopoietic stem cells (HSCs) to mobilize from the bone marrow and to accommodate and function in extramedullary tissues is rather complicated and far from our current understanding. Fortunately, many reports from the studies of drugs and genetics using animals have incidentally found EMH to be involved. Thereby, the molecular basis of EMH could further be elucidated from those animals after cross-comparison. A deeper understanding of the extramedullary hematopoietic niche could help expand stem cells in vitro and establish a better treatment in patients for stem cell transplantation.

    To evaluate the magnetic resonance imaging (MRI) findings of spinal intradural extramedullary schwannomas with pathologic correlation and to determine whether these schwannomas share the imaging features of schwannomas in the peripheral nerves. The MRIs of 17 cases of pathologically proven spinal intradural extramedullary schwannomas were reviewed retrospectively, and cystic changes, enhancement, and intratumoral hemorrhage of the tumors were evaluated. Imaging features known to be common findings of schwannoma in the peripheral nerves, such as encapsulation, the target sign, the fascicular sign, and visualization of entering or exiting nerve rootlets, were also evaluated. The histopathology of the tumors was correlated with the MRI findings. Cystic changes were detected in 14 cases by MRI and in 16 cases by pathology. The most common pattern of enhancement was a thick peripheral septal pattern (70.59%). Intratumoral hemorrhage was detected in four cases on MRI, but in all cases on pathology. Encapsulation was observed in all cases. The fascicular sign was seen in only four cases, and thickening of an exiting rootlet was visualized in one case. None of the cases showed the target sign. Spinal intradural extramedullary schwannomas were typical encapsulated cystic tumors and had few imaging features of schwannomas in the peripheral nerves.

    This study aimed to evaluate the clinical effect of extramedullary fixation combined with intramedullary fixation during the surgical reduction of sagittal mandibular condylar fractures. Twenty-four sagittal fractures of the mandibular condyle in18 patients were fixed by two appliances: intramedullary with one long-screw osteosynthesis or Kirschner wire and extramedullary with one micro-plate. The radiologically-recorded post-operative stability-associated com-plications included the screw/micro-plate loosening, micro-plate twisting, micro-plate fractures, and fragment rotation. The occluding relations, the maximalinter-incisal distances upon mouth opening, and the mandibular deflection upon mouth opening were evaluated based on follow-up clinical examination. Postoperative panoramic X-ray and CT scans showed good repositioning of the fragment, with no redislocation or rotation, no screw/plate loosening, and no plate-twisting or fracture. Clinical examination showed that all patients regained normal mandibular movements, ideal occlusion, and normal maximal inter-incisal distances upon mouth opening. Extramedullary fixation combined with intramedullary fixation is highly recommended for sagittal condylar fractures because of the anti-rotation effect of the fragment and the reasonable place-ment of the fixation appliances.

    To compare the diagnostic performance of whole-body MRI (WBMRI) with haematological parameters for detecting persistent or relapsing disease in patients with multiple myeloma after stem cell transplantation. Sixty-six WBMRI acquisitions were performed in 33 patients with multiple myeloma at two time points after stem cell transplantation. Extent of disease and inter-test dynamics of intra- and extramedullary myeloma manifestations were compared (kappa statistics) with Uniform Response Criteria, comprising haematological parameters. Using data from 66 sequential WBMRI acquisitions in 33 patients, 10 patients (30.3 %) were classified as having progressive disease and 23 (69.7 %) as being in remission. Eight (80 %) of the ten patients with progressive disease revealed intramedullary lesions, and two patients (20 %) had intra- and extramedullary lesions. WBMRI and laboratory tests were concordant in 26/33 (78.8 %) patients. We found an agreement of 51.2 %, 95 % confidence interval 19.8 %-82.6 %, between results from WBMRI and haematological parameters. WBMRI had a sensitivity of 63.6 %, specificity of 86.4 %, PPV of 70.0 %, NPV of 82.6 % and accuracy of 78.8 % for detection of remission. WBMRI allows the detection and exact localisation of intra- and extramedullary myeloma manifestations after stem cell transplantation, but shows only moderate agreement with routinely performed laboratory tests for determination of remission.

    Despite addiction theorists' acknowledgment of the impact of environmental factors on relapse, researchers have not adequately investigated these influences. Ninety-six substance users provided data regarding their perceived risk for relapse, exposure to substances, and involvement in reinforcing activities. These three setting attributes were assessed in their home, work, and community settings. Reuse was assessed 3 months later. When controlling for confounding variables, aspects of the home settings significantly distinguished abstainers from reusers; perceived risk for relapse was the strongest predictor of reuse. Exposure to substances and involvement in reinforcing activities were not robust reuse indicators. The work and community settings were not significant determinants of reuse. These findings offer some initial support for the utility of examining social settings to better understand addiction relapse and recovery. Identification of setting-based relapse determinants provides concrete targets for relapse prevention interventions.

    Extramedullary hematopoiesis (EMH) is a rare disease, where hematological disorder drives extramedullary hematopoietic tumor formation in multiple regions of the body. The present study reports a case of EMH presenting as multiple tumor-like lesions of mediastinum in a 61-year-old male with α-thalassemia, which was subjected to a video-assisted thoracoscopic surgery tissue biopsy to differentiate it from other mediastinal tumors. To date, only three cases of EMH in patients with α-thalassemia have been described in the literature. Patients with EMH typically exhibit no hematological disorder preoperatively and therefore EMH is frequently misdiagnosed. In the present study, along with a literature review of the clinicopathological features of EMH, the diagnosis and treatment of this rare case was discussed, in order to differentiate diagnosis, and particularly to distinguish EHM from extramedullary myeloid sarcoma.

    Full Text Available In total knee arthroplasty, mechanical alignment guides have improved the accuracy of implant alignment, but errors are not uncommon. In the present study, an image-free computer-assisted navigation system was used to analyse the accuracy of an extramedullary (tibial alignment system, which is based on predetermined, fixed anatomical landmarks. Comparisons were made between two surgeons, with different levels of competency in order to determine if experience affected the accuracy of extramedullary tibial jig placement, in either the coronal and sagittal planes or both planes. The results showed that the accuracy of the extramedullary tibial alignment system, in the coronal plane (in up to 80-87% of cases was much better than for posterior slope, and sagittal plane. Surgeon experience was not a significant factor.

Although the occurrence of these diseases together could be coincidental, an association seems immunologically plausible. Thus, relapsing polychondritis might be an unusual systemic manifestation of alopecia areata.

    2013-01-01

    Background Several different surgical techniques have been described to address the coracoclavicular (CC) ligaments in acromioclavicular (AC) joint injuries. However, very few techniques focus on reconstructing the AC ligaments, despite its importance in providing stability. The purpose of our study was to compare the biomechanical properties of two free-tissue graft techniques that reconstruct both the AC and CC ligaments in cadaveric shoulders, one with an extramedullary AC reconstruction and the other with an intramedullary AC reconstruction. We hypothesized intramedullary AC reconstruction will provide greater anteroposterior translational stability and improved load to failure characteristics than an extramedullary technique. Methods Six matched cadaveric shoulders underwent translational testing at 10 N and 15 N in the anteroposterior and superoinferior directions, under AC joint compression loads of 10 N, 20 N, and 30 N. After the AC and CC ligaments were transected, one of the specimens was randomly assigned the intramedullary free-tissue graft reconstruction while its matched pair received the extramedullary graft reconstruction. Both reconstructed specimens then underwent repeat translational testing, followed by load to failure testing, via superior clavicle distraction, at a rate of 50 mm/min. Results Intramedullary reconstruction provided significantly greater translational stability in the anteroposterior direction than the extramedullary technique for four of six loading conditions (p < 0.05). There were no significant differences in translational stability in the superoinferior direction for any loading condition. The intramedullary reconstructed specimens demonstrated improved load to failure characteristics with the intramedullary reconstruction having a lower deformation at yield and a higher ultimate load than the extramedullary reconstruction (p < 0.05). Conclusions Intramedullary reconstruction of the AC joint provides greater stability in the

    Extra-skeletal Ewing's sarcomas are very rare lesions to the spine surgeon, with the intradural, extramedullary lesions being even rarer. Herein we present a patient with an intradural, extramedullary form of Ewing's sarcoma and review the relevant literature. The medical records, operative reports, radiographical studies and histological examinations of a single patient are retrospectively reviewed. A 31-year old male presented with back-pain, right-leg progressive paraparesis, and inability to walk. Both motor and sensory disturbances were revealed on the right leg at the clinical examination. Lumbar MRI showed two lesions. The first one was an intradural, extramedullary lesion at the L2-L3 level, while the second was smaller, located at the bottom of the dural sac. The patient underwent gross total resection of the L2-L3 lesion after a bilateral laminectomy. Histological examination was compatible with Ewing's sarcoma, and was verified by molecular analysis. No other extra-skeletal or skeletal lesion was found. A chemotherapy scheme was tailored to the patients' histological diagnosis. The patient presented with local recurrence and bone metastasis 2 years after his initial diagnosis. A second operation was performed and the follow up of the patient showed no disease progression 18 months after revision surgery. The spine surgeon should be aware of the existence of such rare entities, in order to timely fulfill the staging process and institute the proper therapy. The management of patients with extra-skeletal Ewing's sarcomas involves professionals as members of a multidisciplinary team, all of which should co-operate for the patient's optimal outcome.

    Extramedullary hematopoiesis occurs in children with hemoglobinopathy and chronic anemia. The liver and spleen are often affected first, but other foci can develop to support erythrocyte demand. We report a case of a nine-year-old with beta thalassemia and temporal bone extramedullary hematopoiesis causing ossicular fixation and bilateral conductive hearing loss. There is only one case in the literature describing this phenomenon in pediatric patients, and this is the first case report of bilateral hearing loss from this physiologic phenomenon. Otolaryngologists should consider this etiology in patients with chronic anemia and conductive hearing loss in the absence of otitis media. Published by Elsevier B.V.

    Extramedullary hematopoiesis (EMH) is the production of blood cell precursors outside the bone marrow that occur in various hematological diseases. In patients with thalassemia intermedia, ineffective erythropoiesis drives compensatory EMH in the liver, pancreas, pleura, spleen, ribs and spine. We describe a patient with thalassemia intermedia who presented with acute neurological symptoms caused by paraspinal EMH, which responded well to combination therapy of steroid, hypertransfusion, laminectomy and excision of pseudotumor and hydroxyurea therapy to boost the formation of fetal haemoglobin. Prompt recognition of EMH based on clinical presentation and typical radiological findings should be made. Early treatment is recommended to prevent irreversible damage to the spinal cord.

    We report one year follow up of a case of extramedullary hematopoiesis within the clivus. The imaging findings, brief clinical course, and endoscopic transphenoidal approach are described. A 29-year-old female with thalassemia developed worsening cranial nerve signs. After imaging studies discovered a large clival mass, she underwent endoscopic transphenoidal biopsy of the lesion. Neural compression from exuberant erythrogenesis within tissue normally quiescent of red blood cell production was found to be the etiology of her neural deficit. Treatment for this condition is generally non-operative unless significant neural compression is present. Radiotherapy and anti-neoplastic agents have been used with success.

    To report the clinicopathological correlation of extramedullary hematopoiesis (EMH) of the conjunctiva in a patient with a history of myelofibrosis. Case report. Elevated pink conjunctival lesions developed bilaterally in a 73-year-old man who had been treated for myelofibrosis for 13 years. EMH was detected in the examination of tissue from the lesion of the inferior fornix of the right eye. The appearance of conjunctival lesions in a patient with myelofibrosis may indicate underlying pathology of EMH that may necessitate a change in systemic treatment of this condition.

    Intracranial involvement in extramedullary hematopoiesis (EMH) is rare, but it should be suspected in patients with myelofibrosis presenting with chronic severe headache. We present a 9-year-old girl with known myelofibrosis whose headaches were unresponsive to routine treatment. CT and MRI studies of the brain showed diffuse pachymeningeal thickening. CT examinations of the chest and abdomen had demonstrated bilateral thoracic paraspinal masses caused by EMH, suggesting the possibility that the intracranial involvement might also be related to EMH. The diagnosis was confirmed by sulfur colloid isotope scan. (orig.)

    Langerhans cell histiocytosis (LCH) is a proliferative disorder of dendritic cells which has evaded efforts to clearly define pathogenesis, diagnostic criteria, and therapeutic response markers. Strides have been made at classification with the recent development of a quantified score of disease severity. Splenic involvement is an indicator of poor prognosis, with spleen size its surrogate marker in evaluation and scoring. We describe a case of pediatric LCH with progressive splenomegaly despite treatment, which when examined at splenectomy revealed no LCH involvement but extramedullary hematopoiesis. These findings thus challenge our understanding of splenomegaly as a marker of disease. Copyright © 2011 Wiley Periodicals, Inc.

    Spinal cord compression due to extramedullary hematopoiesis (EMH) is a rare complication of thalassemia and generally presents as paraparesis with sensory impairment. Complete paraplegia is extremely rare in EMH due to thalassemia although it is known to occur in polycythemia vera and sickle cell anemia. Treatment options mostly include surgery and/or radiotherapy. Whereas cases presenting with paraparesis have been treated with either surgery or radiotherapy with equal frequency and efficacy, almost all reported cases with paraplegia have been treated with surgery with or without radiation therapy. We hereby report a case of thalassemia intermedia with paraplegia treated successfully with radiotherapy.

    We report a case of a thalassemia major male patient with back pain associated to severe weakness in lower extremities resulting in the ability to ambulate only with assistance. An urgent magnetic resonance imaging (MRI) of  thoracic and lumbosacral spine was requested. A posterior intraspinal extradural mass lesion compressing the spinal cord at the level of thoracic T5-8 was present, suggesting an extramedullary hematopoietic centre, compressing the spinal cord. He was treated successfully with thalassemia major alone. The patient was treated with blood transfusion, dexamethasone, morphine and paracetamol, followed by radiotherapy in 10 fractions to the spine (daily fraction of 2Gy from T3 to T9, total dose 20 Gy). His pain and neurologic examination quickly improved. A new MRI of the spine, one week after radiotherapy, showed an improvement of the extramedullary hematopoietic mass compression. In conclusion, EMH should be considered in every patient with ineffective erythropoiesis and spinal cord symptoms. MRI is the most effective method of demonstrating EMH. The rapid recognition and treatment can dramatically alleviate symptoms. There is still considerable controversy regarding indications, benefits, and risks of each of modality of treatment due to the infrequency of this disorder.

    Extramedullary hematopoiesis (EH) is a compensatory phenomenon that results in the production of blood cell precursors outside the marrow in patients with chronic hemolytic anemia and ineffective erythropoiesis. EH usually involves the liver, spleen, and lymph nodes. It can also be found at paravertebral, intrathoracic, or pelvic locations. Intracranial EH is a rare entity and often asymptomatic but can sometimes lead to symptomatic tumor-like masses. Treatment options are controversial and include hypertransfusion, surgical excision, radiotherapy, and hydroxyurea (HU). Successful treatment of an intracranial EH mass with HU and blood transfusions in a beta-thalassemia major patient was discussed along with a review of the published literature on intracranial EH in thalassemia. In our patient, the extramedullary hematopoietic mass in the interhemispheric fissure showed a marked improvement after 6 months of HU and hypertransfusion therapy. In the English literature, there are a few cases with intracranial EH and thalassemia, which were treated with different treatment modalities, with different outcomes. There is no standard treatment approach in patients with symptomatic EH. HU with hypertransfusion regimen is a reasonable first-choice modality in treating intracranial EH masses. © 2012 American Association of Blood Banks.

    Multiple myeloma (MM) is characterized by a monoclonal plasma cell population in the bone marrow. Lytic lesions occur in up to 90 % of patients. For many years, whole-body X-ray (WBX) was the method of choice for detecting skeleton abnormalities. However, the value of WBX in relapsing disease is limited because lesions persist post-treatment, which restricts the capacity to distinguish between old, inactive skeletal lesions and new, active ones. Therefore, alternative techniques are necessary to visualize disease activity. Modern imaging techniques such as magnetic resonance imaging, positron emission tomography and computed tomography offer superior detection of myeloma bone disease and extramedullary manifestations. In particular, the properties of nuclear imaging enable the identification of disease activity by directly targeting the specific cellular properties of malignant plasma cells. In this review, an overview is provided of the effectiveness of radiopharmaceuticals that target metabolism, surface receptors and angiogenesis. The available literature data for commonly used nuclear imaging tracers, the promising first results of new tracers, and our pilot work indicate that a number of these radiopharmaceutical applications can be used effectively for staging and response monitoring of relapsing MM patients. Moreover, some tracers can potentially be used for radio immunotherapy. (orig.)

    2013-03-01

    Ectopic extramedullary hematopoiesis (EMH), defined as the formation of blood cells outside the bone marrow, usually occurs in a scenario of chronic anemia when, even after conversion of the bony yellow marrow to red marrow, the body is still unable to meet the demand for red blood cells. Ectopic extramedullary hematopoiesis most commonly occurs in the liver and spleen but may, in fact, occur almost anywhere in the body. Although previous reports have documented EMH presenting as paraspinal masses, such lesions have almost always been associated with a predisposing hematological disorder such as hemolytic anemia, myelofibrosis or myelodysplastic syndromes, thalassemia, polycythemia vera, leukemia, or lymphoma. The authors of this report describe the first reported instance of EMH in a patient presenting with a symptomatic epidural and paraspinal cervical lesion arising from the posterior spinal elements and no known predisposing hematological disease. Initial radiographs revealed a bony lesion arising posteriorly from the C2-3 laminae and spinous processes. Subsequent imaging suggested the diagnosis, which was confirmed by CT-guided biopsy, peripheral blood smears, and bone marrow aspirate. Despite epidural compression and slight displacement of the cervical cord and thecal sac, the patient's symptoms were limited to pain and diminished cervical range of motion. Therefore, surgery was deferred in favor of nonsurgical therapy. Several alternative modalities for the treatment of EMH have been suggested in the literature, including cytotoxic agents and radiotherapy. The authors opted for an approach utilizing directed low-dose radiotherapy of a total of 25 Gy divided in 2.5-Gy fractions. At the 3-month follow-up, the patient continued to be asymptomatic, and MRI demonstrated a significant reduction in the dimensions of the lesion. Extramedullary hematopoiesis with spinal cord compression in the absence of a preexisting hematological disorder has not been described in

    Despite the success of contemporary treatment protocols in childhood acute lymphoblastic leukaemia (ALL), relapse within the central nervous system (CNS) remains a challenge. To better understand this phenomenon, we have analysed the changes in incidence and pattern of CNS relapses in 5564 children enrolled on four successive MRC-ALL trials between 1985 and 2001. Changes in the incidence and pattern of CNS relapses were examined and the relationship with patient characteristics assessed. Factors affecting post-relapse outcome were determined. Overall, relapses declined by 49%. Decreases occurred primarily in non-CNS and combined relapses with a progressive shift towards later (≥30 months from diagnosis) relapses (p<0·0001). Although isolated CNS relapses declined, the proportional incidence and timing of relapse remained unchanged. Age and presenting white cell count were risk factors for CNS relapse. On multivariate analysis, the time to relapse and the trial period influenced post-relapse outcomes. Relapse trends differed within biological subtypes. In ETV6-RUNX1 ALL, relapse patterns mirrored overall trends while in High Hyperdiploidy ALL, these appear to have plateaued over the latter two trial periods. Intensive systemic and intrathecal chemotherapy have decreased the overall CNS relapse rates and changed the patterns of recurrence. The heterogeneity of therapeutic response in the biological subtypes suggests room for further optimisation using currently available chemotherapy. PMID:20016529

    A multicomponent smoking relapse prevention treatment based on Marlatt and Gordon's (1980) model of the relapse process was developed and evaluated. Behavior-analytic methods were used to develop assessment instruments, training situations, and coping responses. The prevention components were presented in the context of a basic broad-spectrum stop-smoking program, and were compared with the basic program plus discussion control, and the basic program alone. Smoking-related dependent variables generally did not differ between groups at any time from pre-treatment to 12 month follow-up. Only the subjects in the relapse prevention condition improved problem-solving and social skills needed to cope with high-risk situations. These subjects also tended to take longer to relapse and smoke fewer cigarettes at the time of relapse. Subjects above the median level of competence on measures of social skill at post-treatment remained abstinent significantly longer. Maintenance of non-smoking was found to be related to the degree of competence with which individuals deal with high-risk situations. Results are discussed in relation to models of compliance with therapeutic regimens.

    An Extramedullary Plasmacytoma (EMP) is characterized by a neoplastic proliferation of clonal plasma cells outside the medullary cavity. EMPs are a rare occurrence compared to other malignant plasma cell disorders and account for approximately 3-5% of plasma-cell neoplasms. Although most cases of EMP are not immediately life threatening at diagnosis, EMPs can progress to Multiple Myeloma (MM) and thus, warrant monitoring. Currently, there are no standard guidelines for when and how to monitor patients who are diagnosed with or treated for a solitary plasmacytoma. We present a case of solitary EMP who was treated adequately and definitively but developed a distinct, non-contiguous subsequent solitary EMP and was only discovered due to surveillance 18 F-Fludeoxyglucose Positron Emission Tomography ( 18 F-FDG) (PET) scan. Uniform surveillance guidelines should be developed and the potential benefits of PET and other imaging techniques as well as their cost should be considered.

    Imaging of the bone marrow by radionuclide scanning was performed using colloids, which are phagocytized by the reticuloendothelial cells of the marrow, or radioiron, which is incorporated into reticulocytes. The use of the former radiopharmaceutical is based on the assumption, generally valid except in aplastic states or after irradiation, that the distribution of hematopoietic and reticuloendothelial tissue in the marrow is similar. Regardless of the method used, active adult marrow is normally distributed only in the axial skeleton and proximal humeri and femurs. Marrow imaging has been used in the evaluation of myeloproliferative disorders, leukemia, lymphoma, aplastic states, malignancy metastatic to marrow, and hemolytic anemia. We report a case of thalassemia major in which the diagnosis of intrathoracic extramedullary hematopoiesis was confirmed with the /sup 99m/Tc sulfur colloid bone marrow scan

    Spinal cord compression due to extramedullary hematopoiesis is an extremely rare complication of thalassemia intermedia. No cases with this complication have been reported in the first decade of life, because masses of heterotropic marrow developed in patients as a result of continuous erythropoiesis. We report the 9-year-old patient suffering from thalassemia intermedia and presenting spinal cord compression. We also review the literature about treatment options, because there is no consensus about the optimal treatment of these patients. Our patient was successfully treated with radiation therapy followed by hydroxyurea. With this combination therapy, he had no recurrence during the 4-year follow-up period. Clinical awareness of this phenomenon with the early treatment is essential for optimizing the successful outcome.

    Review of a case of paraosseous extramedullary hematopoiesis (EMH) affecting the maxillary sinuses and retro-orbital spaces imitating bilateral orbital cellulitis. Maxillofacial EMH causes diagnostic/therapeutic challenges. This case report describes a 4-year-old African American male with sickle cell disease (HbSS) who presented with bilateral orbitofacial swelling. Diagnosis was made with imaging and confirmed with tissue sampling. Partial exchange transfusion was utilized to stop the progression of maxillofacial EMH and to treat the patient's chronic anemia. Follow-up MRI showed regression of orbital and retro-orbital involvement. Early treatment with conservative modalities and close observation may prevent need for more invasive treatments.

Progression to myelofibrosis is usually a late stage complication and presents clinically with refractory cytopenias and extramedullary hematopoiesis (EMH). EMH can occur in any tissue during the course of post-polycythemic myelofibrosis. However, skin and cardiac involvements seems to be very rare. We present a 56-year-old woman with post-polycythemic myelofibrosis refractory to treatment, developing EMH after splenectomy in various organs, exceptionally the skin and the heart. Along with the case, the clinical presentations, treatment options, prognostic significance of EMH and the role of cytogenetics is discussed in the light of the literature.

    Development and growth of hematopoietic tissue outside of the bone marrow is termed extramedullary hematopoiesis (EMH). It occurs in patients with hematological diseases such as myelofibrosis and thalassemia. Liver and spleen are the usual sites of EMH. However, spinal cord compression caused by EMH is a rare complication. A 65-year-old man with myelofibrosis was admitted to our hospital with progressive paraparesis. Thoracic spine MRI revealed epidural masses causing cord compression. Histological examination of the epidural mass showed evidence of EMH consisting of megakaryocytic and erythroid hyperplasia. After surgical decompression and radiotherapy, lower limb weakness and sensory disturbance were significantly improved. MRI showed disappearance of the spinal cord compression. With this therapy, he had no recurrence until he died of myelofibrosis. Spinal EMH should be considered as a differential diagnosis in patients with hematological diseases presenting with paraparesis. Surgical decompression and radiotherapy are effective approaches for the treatment of paraparesis due to EMH.

    Extramedullary hematopoiesis (EMH) occurs in patients with various hematologic disorders involving a chronic increase in the production of red blood cells, and is often associated polycythemia vera and sickle cell anaemia, but is less common with thalassemia especially with hemoglobin E-beta thalassemia. Spinal cord compression due to EMH is a extremely rare complication of thalassemia and may present with paraparesis or paraplegia with or without sensory impairment. Treatment options mostly include surgery and/or radiotherapy. Whereas cases presenting with paraplegia have been treated with either surgery or radiotherapy with equal frequency and efficacy, almost all reported cases with paraplegia have been treated with surgery with or without radiation therapy. We hereby report a case of hemoglobin E-beta thalassemia with paraplegia treated successfully with radiotherapy.

    We describe a 16 year-old male with β thalassemia major and gait disturbances that had not been given blood transfusions due to a severe childhood transfusion reaction. Thoracic spine MRI demonstrated hematopoietic marrow throughout the spine and epidural masses causing cord compression consistent with extramedullary hematopoiesis (EMH). After treatment with steroids, radiotherapy and monitored blood transfusions, the patient demonstrated significant improvement of his paraspinal lesions and near complete resolution of his neurological symptoms. While EMH causing cord compression in adolescents is rare in the current era of bone marrow transplantation or chronic transfusions, it should be considered when thalassemia major patients present with neurological deficits. The well defined imaging features of EMH can play a central role in its diagnosis and management, especially because surgical and / or radiotherapeutic intervention are often considered in cases of failed medical treatment.

  12. Fine needle aspiration cytology in feline skeletal muscle as a diagnostic tool for extramedullary plasmacytoma

    Directory of Open Access Journals (Sweden)

    D.B. Martins

    Full Text Available ABSTRACT Extramedullary noncutaneous plasmacytoma (ENP is a myeloproliferative disorder of plasma cells that rarely affects cats. This paper describes an ENP case revealed by fine needle aspiration cytology (FNAC of the mass in the skeletal muscle of an 8-month-old, male, mixed breed cat, which had a nodule in the left hind limb. The rapid immunoassay test confirmed the presence of feline leukemia virus (FeLV. The animal necropsy macroscopically showed the nodule came from the semimembranosus muscle. Histopathological examination ratified the cytological findings. Thus, this paper alerts to the existence of plasmacytoma located in the skeletal muscle of feline species. FNAC is a quick and efficient method for diagnosis of ENP.

    A 2.5-year-old spayed female American Pit Bull Terrier dog presented with a primary complaint of chronic refractory ascites. The dog's CBC displayed a moderate to severe macrocytic, hypochromic, nonregenerative anemia, and a moderate leukopenia as result of a moderate neutropenia and monocytopenia. Microscopic examination of the blood smear showed marked anisocytosis, mild polychromasia, mild acanthocytosis and ovalocytosis, moderate schistocytosis and poikilocytosis, and 4 metarubricytes/100 WBC. Abdominal ultrasonography revealed a homogenous, mild to moderately hyperechoic appearing liver as well as marked amounts of speckled anechoic to slightly hypoechoic peritoneal fluid. Cytology of the ascitic fluid demonstrated a sterile transudate, with evidence of a chronic inflammatory reaction as well as erythroid and myeloid precursor cells, and a few megakaryocytes with occasional micromegakaryocytes. Histologic sections of bone marrow, spleen, and liver were examined, using routine H&E stains, as well as a variety of immunohistochemistry and other special stains. Histopathology of the bone marrow and spleen revealed varying degrees of fibrosis, erythroid, and myeloid hyperplasia, as well as multiple small hyperplastic clusters of megakaryocytes. The megakaryocytes displayed many features of atypia such as increased cytoplasmic basophilia and occasional abnormal chromatin clumping with mitoses. Histopathologic examination of the liver disclosed evidence of mild extramedullary hematopoiesis. This case represents the first report of canine idiopathic myelofibrosis associated with peritoneal extramedullary hematopoiesis, resulting in refractory ascites. Although idiopathic myelofibrosis is a relatively rare condition in dogs, this case demonstrates that ascites caused by peritoneal implants of hematopoietic tissue may be the initial manifestation of myelofibrosis. © 2016 American Society for Veterinary Clinical Pathology.

  15. Ferrokinetic study of splenic erythropoiesis: Relationships among clinical diagnosis, myelofibrosis, splenomegaly, and extramedullary erythropoiesis

    Splenic erythropoiesis was demonstrated by surface counting of 59 Fe in 129 of 1,350 ferrokinetic studies performed over a 15 year period. These 129 studies were carried out in 108 patients, including 40 with chronic myelogenous leukemia (CML), 24 with agnogenic myeloid metaplasia (AMM), 18 with polycythemia vera (PV), six with a myelodysplastic syndrome, five with acute leukemia, three with prostate or breast carcinoma, two each with aplastic anemia or Hodgkin's disease, and one each with idiopathic thrombocythemia, multiple myeloma, chronic renal failure, or treated hypopituitarism. Splenomegaly was present in 83% of the studies and hepatomegaly in 72%. Grade II-III myelofibrosis was demonstrated in 62% of the cases. Hepatic erythropoiesis was present in 77% of the studies (only 38% in PV), and marrow erythropoiesis was undetectable in 33%. Total erythropoiesis was about twice normal (range 0.2 to 8 times normal) but was ineffective to varying degrees in 86% of the studies. Relationships between organomegaly, myelofibrosis, and extramedullary erythropoiesis, as well as differences among clinical disorders, are discussed. Differences observed between CML in chronic or blastic phase suggested that the erythroid cell line was involved in the proliferative process. It is concluded that splenic erythropoiesis (1) is encountered in a variety of clinical conditions; (2) is not necessarily associated with splenomegaly or myelofibrosis, even in the myeloproliferative disorders; (3) is part of a predominantly extramedullary (in the liver as well as in the spleen), expanded, and largely inefficient total erythropoiesis; and (4) can be evaluated in a semiquantitative manner by surface counting

    Chronic myelogenous leukemia (CML) is a myeloproliferative disorder characterized by the Philadelphia (Ph) chromosome generated by the reciprocal translocation t(9,22)(q34;q11). The natural progression of the disease follows a biphasic or triphasic course. Most cases of CML are diagnosed in the chronic phase. Extramedullary blast crisis rarely occurs during the course of CML, and is extremely rare as the initial presentation of CML. Here, we report the case of a 32-year-old female with enlarged neck lymph nodes and fatigue. She was diagnosed with B-lymphoblastic leukemia/lymphoma with possible mixed phenotype (B/myeloid) by right neck lymph node biopsy at an outside hospital. However, review of her peripheral blood smear and her bone marrow aspirate and biopsy showed features consistent with CML, which was confirmed by PCR and karyotyping. An ultrasound-guided right cervical lymph node core biopsy showed a diffuse infiltrate of blasts, near totally replacing the normal lymph node tissue, admixed with some hematopoietic cells including megakaryocytes, erythroid precursors and maturing myeloid cells. By flow cytometry and immunohistochemistry, the blasts expressed CD2, cytoplasmic CD3, CD5, CD7, CD56, TdT, CD10 (weak, subset), CD19 (subset), CD79a, PAX-5 (subset), CD34, CD38, CD117 (subset), HLA-DR (subset), CD11b, CD13 (subset), CD33 (subset), and weak cytoplasmic myeloperoxidase, without co-expression of surface CD3, CD4, CD8, CD20, CD22, CD14, CD15, CD16 and CD64, consistent with blasts with mixed phenotype (T/B/myeloid). A diagnosis of extramedullary blast crisis of CML was made. Chromosomal analysis performed on the lymph node biopsy tissue revealed multiple numerical and structural abnormalities including the Ph chromosome (46-49,XX,add(1)(p34),add(3)(p25),add(5)(q13),-6,t(9;22)(q34;q11.2),+10,-15,add(17)(p11.2),+19, +der(22)t(9;22),+mar[cp8]). After completion of one cycle of combined chemotherapy plus dasatinib treatment, she was transferred to City of Hope

    Few marijuana smokers in treatment achieve sustained abstinence, yet factors contributing to high relapse rates are unknown. Study 1: data from five inpatient laboratory studies assessing marijuana intoxication, withdrawal, and relapse were combined to assess factors predicting the likelihood and severity of relapse. Daily, nontreatment-seeking marijuana smokers (n = 51; 10 ± 5 marijuana cigarettes/day) were enrolled. Study 2: to isolate the effects of cigarette smoking, marijuana intoxication, withdrawal, and relapse were assessed in daily marijuana and cigarette smokers (n = 15) under two within-subject, counter-balanced conditions: while smoking tobacco cigarettes as usual (SAU), and after at least 5 days without cigarettes (Quit). Study 1: 49% of participants relapsed the first day active marijuana became available. Tobacco cigarette smokers (75%), who were not abstaining from cigarettes, were far more likely to relapse than non-cigarette smokers (odds ratio: 19, p marijuana administration and those with more negative affect and sleep disruption during marijuana withdrawal were more likely to have severe relapse episodes (p 87%) relapsed to marijuana whether in the SAU or Quit phase. Tobacco cigarette smoking did not significantly influence relapse, nor did it affect marijuana intoxication or most symptoms of withdrawal relative to tobacco cessation. Daily marijuana smokers who also smoke cigarettes have high rates of marijuana relapse, and cigarette smoking versus recent abstinence does not directly influence this association. These data indicate that current cigarette smoking is a clinically important marker for increased risk of marijuana relapse. Copyright © 2013 Society of Biological Psychiatry.

    We present the case of a 42-year-old man with a painful mass lesion in the right shoulder that was detected by contrast-enhanced computed tomography (CT) and 18 F-fluoro-2-deoxyglucose ( 18 F-FDG) positron emission tomography (PET)/CT. Excisional biopsy revealed infiltration of plasma cells with anaplastic features, consistent with solitary plasmacytoma (PC). Serum analysis showed elevation of serum free lambda light chain levels (27.78 mg/l), with an abnormally high kappa:lambda ratio (2.33) and high total proteins (10.4 g/dl). Serum protein electrophoresis revealed an M spike in the gamma-globulin region (56.1 %=5.8 g/dl). Subsequently, 18 F-FDG PET/CT revealed another hypermetabolic mass in the right lobe of the liver. CT-guided biopsy of the liver lesion revealed plasma cell myeloma, consistent with multiple myeloma. Multiple myeloma presenting as nodular liver masses is very rare in clinical practice. In a retrospective review of more than 2,000 patients, Talamo et al. reported only nine cases where there was nodular involvement of the liver by multiple myeloma. The organ most commonly involved was the liver, followed by pancreas, stomach, peritoneum with malignant ascites, colon, rectum, duodenum and ileum. Therefore, the literature published thus far has been limited to a few reports and case series. Among these reports, some had demonstrated the PET or PET/CT findings of nodular liver involvement of multiple myeloma. About 10 % of the solitary myelomas appeared as extramedullary PC or solitary PC of bone. In spite of the advances in therapy, the treatment of multiple myeloma is still palliative. However, solitary PC could be cured by resection or radiation therapy. Thus, differentiation between PC and multiple myeloma is essential in making a decision for the appropriate therapeutic regimen. 18 F-FDG PET/CT has the unique ability to detect and characterize malignant lesions in one single examination.

    2017-09-01

    Schizophrenia is a chronic and debilitating mental illness characterised by periods of relapse that require resource intensive management. Quantifying the cost of relapse is central to the evaluation of the cost effectiveness of treating schizophrenia. We aimed to undertake a comprehensive search of the available literature on the cost of relapse. We performed a search on multiple databases (MEDLINE, Embase, PsycINFO and Health Management Information Consortium) for any study reporting a cost of relapse or data from which such a cost could be calculated. Costs are reported in 2015 international dollars. We found 16 studies reporting costs associated with relapse over a defined period of time and identified a cost associated with hospitalisation for relapse in 43 studies. Eight clinical decision analyses also provided cost estimates. Studies from the US report excess costs of relapse of $6033-$32,753 (2015 Purchasing Power Parity dollars [PPP$]) over periods of 12-15 months. European studies report excess costs of $8665-$18,676 (2015 PPP$) over periods of 6-12 months. Estimates of the cost of hospitalisation for relapse are more diverse, and associated with marked differences in typical length of stay across jurisdictions. Wide ranges in the estimated cost of relapse may reflect differences in sample section and relapse definition as well as practice styles and differences in resource costs. Selection of the most appropriate cost estimate should be guided by the definition of relapse and the analysis setting.

    Extramedullary hematopoiesis (EMH) is induced in spleens due to various diseases. The aim of this study is to investigate the role of spleen in cyclophosphamide (CTX)-induced hematosuppression and EMH in mice. Balb/c mice were IP injected with 300 mg/kg CTX 2 weeks after splenectomy or sham operation and randomly sacrificed 1, 3, 7, 14, and 21 days after injection. Blood samples were collected, and spleens were weighed, histologically analyzed, and then used for flow cytometry. There were significant differences in white blood count, red blood count, platelet numbers and hemoglobin concentration between the splenectomized and sham-operated mice after CTX injection. The cellularity of the spleen was reduced 3 days following CTX treatment but then rose 7 days after CTX treatment. The numbers of colony-forming units in the spleen reached a peak 7 days after CTX injection, then declined. Flow cytometry demonstrated the percentage of CD34(+) and CD117(+) cells in the spleen increased 7 days after CTX injection, indicating the hematopoietic stem and progenitor cells in the spleen. The study indicates that EMH occurs as a compensatory reaction to CTX-induced hematosuppression in the murine spleen, implying that conservation of the spleen may promote the recovery of cancer patients from chemotherapy-induced hematosuppression.

    We present the case of a 7-year-old Cameroonian girl with sickle cell disease (SCD) who presented with progressive abdominal distension, fever, severe anemia, respiratory distress, and fatigue. Abdominal ultrasound showed a 15.3 cm × 11.5 cm × 15.5 cm solid echogenic mass within the left lobe of the liver. Fine-needle aspiration showed features of extramedullary hematopoiesis (EMH). Despite transfusions, antibiotics, and initiation of hydroxyurea the patient died of respiratory failure during the hospital stay. There is a paucity of information on EMH in the pediatric sickle cell population, especially from resource-limited settings such as western Africa. EMH, however, is a known complication of SCD and should be considered in patients presenting with mass lesions in the setting of chronic anemia. With limited therapeutic interventions for EMH, including radiation and hydroxyurea, the emphasis should be on improving overall treatment of patients with chronic and untreated hemolytic anemia, especially in low-income countries. © 2015 Japan Pediatric Society.

    Extramedullary hematopoiesis (EMH) refers to the development of foci of hematopoiesis outside its normal location in the bone marrow. This occurs normally during fetal development but is abnormal postpartum. The most common sites of EMH are the spleen and liver. The phenomenon occurs in a number of disease states, notably in myelofibrosis, thalassemia, immune thrombocytopenic purpura, sickle cell anemia, polycythemia vera, and myelodysplastic syndrome. Affected patients often develop symptoms related to the location of the EMH. Reported treatments include red blood cell transfusions, surgical excision, decompressive laminectomy in cases of cord compression, chemotherapy, and irradiation. Radiation therapy is highly effective for treating hematopoietic tissue because such tissues are extremely radiosensitive. Megavoltage helical tomotherapy is a technical advance in the delivery of radiation therapy, allowing more conformal and precise treatments. The present case report describes a patient with the diagnosis of atypical chronic myeloid leukemia and myelofibrosis who subsequently developed EMH of the pericardium with effusion and tamponade. By utilizing tomotherapy we were able to treat the pericardium while sparing much of the myocardium. The patient tolerated treatment well without acute adverse effects. His symptoms were alleviated, but he died approximately 1 year later.

    Extramedullary hematopoiesis (EMH) is induced during pregnancy to support rapid expansion of maternal blood volume. EMH activation requires hematopoietic stem cell (HSC) proliferation and mobilization, processes that depend upon estrogen receptor α (ERα) in HSCs. Here we show that treating mice with estradiol to model estradiol increases during pregnancy induced HSC proliferation in the bone marrow but not HSC mobilization. Treatment with the alternative ERα ligand 27-hydroxycholesterol (27HC) induced ERα-dependent HSC mobilization and EMH but not HSC division in the bone marrow. During pregnancy, 27HC levels increased in hematopoietic stem/progenitor cells as a result of CYP27A1, a cholesterol hydroxylase. Cyp27a1-deficient mice had significantly reduced 27HC levels, HSC mobilization, and EMH during pregnancy but normal bone marrow hematopoiesis and EMH in response to bleeding or G-CSF treatment. Distinct hematopoietic stresses thus induce EMH through different mechanisms. Two different ERα ligands, estradiol and 27HC, work together to promote EMH during pregnancy, revealing a collaboration of hormonal and metabolic mechanisms as well as a physiological function for 27HC in normal mice.

    Extramedullary hematopoiesis (EMH) is occasionally reported in idiopathic myelofibrosis and is generally found in the liver, spleen, and lymph nodes several years after diagnosis. Myelofibrosis presenting as spinal cord compression, resulting from EMH tissue is very rare. A 39-yr-old man presented with back pain, subjective weakness and numbness in both legs. Sagittal magnetic resonance imaging showed multiple anterior epidural mass extending from L4 to S1 with compression of cauda equina and nerve root. The patient underwent gross total removal of the mass via L4, 5, and S1 laminectomy. Histological analysis showed islands of myelopoietic cells surrounded by fatty tissue, consistent with EMH, and bone marrow biopsy performed after surgery revealed hypercellular marrow and megakaryocytic hyperplasia and focal fibrosis. The final diagnosis was chronic idiopathic myelofibrosis leading to EMH in the lumbar spinal canal. Since there were no abnormal hematological findings except mild myelofibrosis, additional treatment such as radiothepary was not administered postoperatively for fear of radiotoxicity. On 6 month follow-up examination, the patient remained clinically stable without recurrence. This is the first case of chronic idiopathic myelofibrosis due to EMH tissue in the lumbar spinal canal in Korea. PMID:18162730

    FTY720 (also called fingolimod) is recognized as an immunosuppressant and has been approved by the Food and Drug Administration to treat refractory multiple sclerosis. However, long-term administration of FTY720 potentially increases the risk for cancer in recipients. The underlying mechanisms remain poorly understood. Herein, we provided evidence that FTY720 administration potentiated tumor growth. Mechanistically, FTY720 enhanced extramedullary hematopoiesis and massive accumulation of myeloid-derived suppressor cells (MDSCs), which actively suppressed antitumor immune responses. Granulocyte-macrophage colony-stimulating factor (GM-CSF), mainly produced by MDSCs, was identified as a key factor to mediate these effects of FTY720 in tumor microenvironment. Furthermore, we showed that FTY720 triggers MDSCs to release GM-CSF via S1P receptor 3 (S1pr3) through Rho kinase and extracellular signal-regulated kinase-dependent pathway. Thus, our findings provide mechanistic explanation for the protumorigenic potentials of FTY720 and suggest that targeting S1pr3 simultaneously may be beneficial for the patients receiving FTY720 treatment.

    Two patients with sarcoma, one with recurrent osteosarcoma of the spine and the other with metastatic synovial cell sarcoma, were treated with high-dose chemotherapy that produced severe leukopenia. The patients received granulocyte colony-stimulating factor (G-CSF) to stimulate the bone marrow (480 mg given subcutaneously twice daily for 5 to 7 days); their responses were seen as a marked increase in peripheral leukocyte count with no change in the erythrocyte or platelet counts. The patients had fluorine-18 fluorodeoxyglucose (F-18 FDG) imaging 24 hours after the end of G-CSF treatment. Diffusely increased uptake of F-18 FDG was seen in the bone marrow in both patients. In addition, markedly increased uptake in the spleen was noted in both, indicating that the spleen was the site of extramedullary hematopoiesis. The patients had no evidence of splenic metastases. The first patient had a history of irradiation to the dorsal spine, which was less responsive to G-CSF administration than was the nonirradiated lumbar spine.

    Full Text Available BACKGROUND Plasmacytomas are rare plasma cell tumours occurring consequent to monoclonal proliferation of plasma cells. They are divided into Solitary bone plasmacytoma, Extramedullary plasmacytoma (EMP and Multiple myeloma. EMPs are commonly housed in the head and neck region with a predilection to the mucosa associated lymphoid tissue in the aerodigestive tract. The nasal cavity, paranasal sinuses, and nasopharynx are the most common sites. OBJECTIVE We describe our experience with this tumour owing to its clinical rarity and a different way of presentation. METHODS After complete surgical excision of a nasal mass presenting in a young male with features masquerading that of Juvenile Nasopharyngeal Angiofibroma, a diagnosis of plasma cell tumour was made on histopathological analysis which was confirmed using immunohistochemistry. Serum electrophoresis, urine Bence Jones proteins, complete skeletal survey were done to rule out any progression into multiple myeloma. Radiation therapy was given with 45 Gy in 25 fractions at 1.8 Gy per day, 5 days a week. RESULTS Followup after 2 years showed no recurrence locally as well as in regional nodes. CONCLUSION Given to the rarity of the tumour, undefined manner of presentation and a predominant prevalence in the head and neck region, every otolaryngologist should keep EMP in mind while considering sinonasal masses. A multidisciplinary approach with a combination of surgery and radiotherapy is found to benefit the patient significantly. A long term watch out for progression to MM is mandatory to commence early treatment and thus prolonged disease-free survival from the same.

    Full Text Available Extramedullary plasmacytoma (EMP is a rare neoplasm of plasma cells, described in soft tissue outside the bone marrow. EMP of the larynx represents 0.04 to 0.45% of malignant tumors of the larynx. A male of 57 years old presented with hoarseness, dyspnea, and biphasic stridor of 2 months. The indirect laryngoscopy (IL revealed severe edema of the posterior commissure and a polypoid mass in the right posterior lateral subglottic wall. A biopsy of the subglottic mass was performed by a direct laryngoscopy (DL. The histopathologic diagnosis was EMP CD138+, therefore radiotherapy was given at 54 Gy in 30 sessions. The patient had an adequate postoperative clinical course and a new biopsy was performed having tumor-free margins. All laryngeal lesions should be biopsied prior to treatment to determine an accurate diagnosis to guide a proper management of the condition. Radiation therapy to the EMP is considered the treatment of choice, having local control rates of 80% to 100%. The subglottis is the least accessible area of view and the least frequent location of a laryngeal mass, nevertheless the otolaryngologist should always do a complete and systematic exam of the larynx when a tumor is suspected, to detect diagnoses such as a subglottic plasmacytoma.

    Full Text Available Multiple myeloma and other plasma cell disorders are characterized by production of a large number of plasma cells in the bone marrow. On the other hand, plasmacytoma results from proliferation of abnormal plasma cells in the soft tissue or skeletal system. Neurological complications are frequently observed in these diseases. The most commonly known complications among those complications are spine fractures, spinal cord compressions, and peripheral neuropathies. Although neurological involvements are common in plasmacytomas, extramedullary spinal epidural localizations have been reported very rarely. In this case report, we aimed to present a plasmacytoma case that presented with acute onset of upper extremity monoparesis. A 40-year-old woman was admitted to our clinic with complaints of sudden weakness and numbness in her left arm following neck and left arm pain. Emergency cervical magnetic resonance imaging (MRI revealed an epidural mass and the patient underwent emergency surgery. The patient showed improvement post-operatively and the pathology was reported as plasmacytoma. Following hematology consultation, systemic chemotherapy was initiated and radiotherapy was planned after wound healing.

    Twelve cases of benign extramedullary tumors in the high cervical region and at the foramen magnum were experienced during past five years among eighty all spinal and paraspinal tumors. The diagnosis of masses in this region is very difficult because of the variety of clinical course, symptoms and neurological findings as pointed out by many reporters. Also in our cases, 70 % of the patients complained of the deteriorated motor weakness of the upper or lower extremities on admission, though they had noticed the onset of slight neck or occipital pain a few years ago. Neurological examination on admission clearly showed the symptom of myelopathy except in two cases with a tumor at the foramen magnum and C/sub 1/ level. The percentage of positive findings of plain X-rays was 50 %, that of metrizamide myelography was 92 % and that of IV. e. CT and met. e. CT was 100 %. NMR-CT was performed in 2 cases, and in one of them it was useful in confirming the tumor configuration and extension. Five interesting cases were described mainly from the neuroradiological aspects. Finally the differentiation between meningioma and neurinoma was discussed from the aspects of myelogram, CT and NMR-CT. As already pointed out, it is most important not to forget the existence of tumors in this region when one comes across the confused symptoms, afterwards not to overlook the slight positive neurological and neuroradiological findings.

    Primary myelofibrosis belongs to the group of myeloproliferative syndromes. Extramedullary hematopoiesis in the liver can lead to portal hypertension. We report a case of a patient with life-threatening, endoscopically not treatable bleeding from esophageal varices due to extramedullary hematopoiesis of the liver that was successfully treated with placement of a transjugular intrahepatic porto-systemic stent-shunt (TIPS). Therapy of variceal bleeding by TIPS insertion was successful. During a 29-month follow-up, no hepatic failure, hepatic encephalopathy, or further variceal bleeding episode occurred. TIPS placement is a well-established procedure for the treatment of complications due to portal hypertension mainly due to liver cirrhosis. This report illustrates that TIPS placement can also be a promising treatment option in patients with primary myelofibrosis and portal hypertension due to extramedullary hematopoiesis.

    Leukemia is a group of malignant diseases involving peripheral blood and bone marrow. Extramedullary tumor manifestation in leukemia can also occur. They more often involve lymph nodes, skin, and bones. Intramuscular leukemic relapse (ILR) is very unusual. The aim of this analysis was to summarize the reported data regarding clinical signs and radiological features of ILR. The PubMed database was searched for publications related to ILR. After an analysis of all identified articles, 20 publications matched the inclusion criteria. The authors of the 20 publications were contacted and provided imaging of their cases for review. The following were recorded: age, gender, primary diagnosis, clinical signs, pattern, localization and size of the intramuscular leukemic relapse. Images of 16 patients were provided [8 computer tomographic (CT) images and 15 magnetic resonance images, MRI]. Furthermore, one patient with ILR was identified in our institutional database. Therefore, images of 17 patients were available for further analysis. Overall, 32 cases with ILR were included in the analysis. In most cases acute myeloid leukemia was diagnosed. Most ILRs were localized in the extremities (44 %) and in the extraocular muscles (44 %). Clinically, ILR manifested as local pain, swelling and muscle weakness. Radiologically, ILR presented most frequently with diffuse muscle infiltration. On postcontrast CT/MRI, most lesions demonstrated homogeneous enhancement. ILRs were hypo-/isointense on T1w and hyperintense on T2w images. ILR manifests commonly as focal pain, swelling and muscle weakness. ILR predominantly involved the extraocular musculature and the extremities. Radiologically, diffuse muscle infiltration was the most common imaging finding. (orig.)

    Brainstem intramedullary schwannomas (ISs) are extremely rare. Various theories have been suggested to explain its origin. It was first speculated that ISs arise from the region where the nerve roots lose their sheaths on penetrating the pia mater. Later, it was further predicted that ISs would contain both intra- and extramedullary parts and would be shaped like a dumbbell. However, no cases reported previously can support this assumption adequately. A 40-year-old woman presented with constant cervical pain, accompanied by progressive weakness of upper extremities and glove distribution numbness. Magnetic resonance imaging of the brain revealed a rare intra- and extramedullary dumbbell-shaped lesion of the medulla oblongata, which was partially removed via a midline suboccipital craniectomy. Histologic and immunohistochemical examinations confirmed the diagnosis of schwannoma. Routine imaging performed 20 months after the initial resection revealed a regrowth of the intramedullary part, which was subsequently partially removed through a far-lateral approach, with symptoms alleviated. At 2-year follow-up, there continued to be no radiologic or clinical evidence of regrowth. To date and to our knowledge, there are only 16 reported cases of brainstem ISs, none of which contained both intra- and extramedullary components. We believe this is the first report of dumbbell schwannoma of the medulla oblongata with adequate radiologic evidence. The relevant literature is reviewed, and an assumption has been proposed that dumbbell or surfacing ISs arising near entry zones of sensory nerves, mixed cranial nerves, or ventral root may originate from the aberrant Schwann cells.

    Intramedullary neuroepithelial cysts are extremely rare and only 15 cases have been reported in the literature. Clinico-radiological features are not indicative of a specific diagnosis; for this reason, diagnosis is based mainly on the histological features. In the literature, total surgical removal is considered the treatment of choice. The risk of recurrence is higher after partial removal and in cases of occlusion of intra-extramedullary shunt. For this reason, a surgical strategy that ensures the shunt patency in case of incomplete removal of the cyst becomes a very safe option for treatment of this pathology. We report the case of a 51-year-old woman who was found to have a dorsal (D9) intramedullary neuroepithelial cyst. She underwent surgical treatment with partial removal and placement of a Nelaton drainage device (8 French) inside the intra-extramedullary shunt. The patient experienced a complete regression of preoperative symptoms and magnetic resonance imaging (MRI) follow-up showed no radiological evidence of recurrence 24 months after surgical treatment. Spinal ependymal cysts show a high frequency of recurrence, especially in cases of partial removal of the cyst wall. Unfortunately, the cyst walls are often closely adherent to the spinal cord, making total removal impossible. Intra-extramedullary shunting is a viable option, although there is a high frequency of recurrence in cases of obstruction of the shunt. Placing an 8 Ch Nelaton drain between the dorsal columns is a reliable technique, especially in cases of partial removal. In fact, it allows continuous drainage of cyst fluid and subsequent resolution of symptoms, and it decreases the incidence of recurrences due to obstruction of the shunt.

    Extramedullary hematopoiesis (EMH) is evidenced by erythropoietic masses, which occurs as a compensatory mechanism to overcome hypoxia during chronic anemia. EMH masses in spinal cord could lead to cord compression and neurological symptoms. Besides transfusion, radiotherapy, and surgery, hydroxyurea (HU) is also a treatment strategy in EMH. We described four cases of beta thalassemia with EMH who were treated with HU as a monotherapy. INTERVENTION (AND TECHNIQUE): HU therapy was done in all patients without any transfusion during therapy. HU is a good treatment option for patients with EMH and it could be a substitute for radiotherapy and invasive surgery or regular blood transfusion.

    The surgical approaches for spinal tumors, to a great extent, have been developed in accordance with the developments in medical technology. Today, many surgical techniques are implemented as anterior, anterolateral, posterior, posterolateral and combined approaches. Due to its low morbidity, the posterior approach is the more preferred one. Laminectomy is a widely used technique, especially in neoplastic lesions. However, following laminectomy, there are numerous complications such as instability, kyphotic deformity and scar formation. In this paper, the excision of a tumor that was located intradural-extramedullary at the C3-C7 level with the cervical hemilaminoplasty technique is described. A 47-year-old female patient presented to our clinic with increasing complaints of neck and left arm pain, left arm numbness and searing pain for the last 10 years. On examination, hypoesthesia at the C4-7 dermatomes in the left upper extremity, an increase in deep tendon reflexes, and bilateral positive Hoffmann reflexes were observed. C3-C7 laminae were opened unilaterally on the right side with a midline skin incision. The laminae were drilled with a high-speed drill to provide a wide opening, both on the midline obliquely and from the border of the lamina-facet joint. After the tumor was totally excised, hemilaminae were placed into the previous position and reconstructed with mini-plates and screws. Cervical hemilaminoplasty provides a wide field of vision in tumor surgery of this region. Besides, the reconstruction of hemilaminae is important for stability. As the integrity of the spinal canal is preserved during reoperations of this region, the risk of complications is decreased.

    Primary myelofibrosis (PMF) is an uncommon form of myeloproliferative neoplasm (MPN) characterized by a proliferation of predominantly megakaryocytes and granulocytes in the bone marrow that, in fully-developed disease, is associated with reactive deposition of fibrous connective tissue, extramedullary hematopoiesis (EMH), and splenomegaly. Kidney involvement is rare and clinically presents with proteinuria, nephrotic syndrome, and renal insufficiency. Renal damage can be due to EMH and glomerulopathy. Renal EMH presents three patterns: infiltration of the interstitium with possible renal failure caused by functional damage of parenchyma and vessels, infiltration of capsule and pericapsular adipose tissue, and sclerosing mass-like lesions that can cause hydronephrosis and hydroureter with obstructive uropathy and renal failure. Glomerulopathy associated with PMF is rarely described, ranging from 1 month to 18 years from diagnosis of the neoplasm to renal biopsy. It is characterized by expansion and hypercellularity mesangial, segmental sclerosis, features of chronic thrombotic microangiopathy (TMA), and intracapillary hematopoietic cells infiltrating in absence of immune-mediated glomerulonephritis. We present a nephrotic syndrome in PMF-related glomerulopathy, associated with EMH, without renal failure, in a patient under treatment for 2 years with JAK2 inhibitor ruxolitinib. Despite treatment, the patient died 7 months after renal biopsy. Nephrologists still know very little about this topic and there is no homogeneous data about incidence, pathogenesis, and optimal treatment of this poor prognostic PMF-associated nephrotic syndrome. We focus on data in the literature in the hope of stimulating hematologists, nephrologists, pathologists to future studies about the natural history of renal involvement, useful for optimal management of this rare pathology.

    Symptomatic extramedullary hematopoiesis (EH) is a rare but potentially severe phenomenon which occurs in β-thalassemia. There are no treatment guidelines. Retrospective single centre study including the cases of symptomatic EH encountered between 1997 and 2014 in a unit specialised in red blood cell genetic disorders. Description of clinical, biological and radiological characteristics of the patients, treatments received, and outcomes. Among 182 β-thalassemia patients followed during the study period, 7 cases of symptomatic EH were diagnosed. They were 5 men and 2 women, and their mean age was 37 years. Four patients were splenectomised, two patients were regularly transfused, and four patients had already received erythropoietin. EH was localised in intravertebral areas and responsible for dorsal spinal cord compression in 5 patients, in paravertebral dorsal area in 1 patient, and in presacral area in 1 patient. The mean hemoglobin level at diagnosis was 7.9 g/dL. Treatment administered included: red cell transfusion in 6 cases, associated with hydroxyurea in 5 cases and/or radiotherapy in 3 patients. One patient was treated with surgery and HU. After a median follow-up of 41 months, clinical recovery was complete in 2 patients and partial in 5 patients. EH must be suspected in β-thalassemia in patients presenting clinical signs of organ compression, and a typical radiological aspect. The functional prognosis depends on the rapidity of treatment, which includes red blood cell transfusion, hydroxyurea, radiotherapy, and rarely surgery. Long-term outcome is uncertain.

    Cyclophosphamide (CY) is a chemotherapeutic agent used for cancer and immunological diseases. It induces cytotoxicity of bone marrow and causes myelosuppression and extramedullary haematopoiesis (EMH) in treated patients. EMH is characterized with the emergence of multipotent haematopoietic progenitors most likely in the spleen and liver. Previous studies indicated that a Chinese medicine, ginsenoside Rg1, confers a significant effect to elevate the number of lineage (Lin(-) ) Sca-1(+) c-Kit(+) haematopoietic stem and progenitor cells (HSPCs) and restore the function of bone marrow in CY-treated myelosuppressed mice. However, whether the amelioration of bone marrow by Rg1 accompanies an alleviation of EMH in the spleen was still unknown. In our study, the cellularity and weight of the spleen were significantly reduced after Rg1 treatment in CY-treated mice. Moreover, the number of c-Kit(+) HSPCs was significantly decreased but not as a result of apoptosis, indicating that Rg1 alleviated EMH of the spleen induced by CY. Unexpectedly, the proliferation activity of c-Kit(+) HSPCs was only up-regulated in the spleen, but not in the bone marrow, after Rg1 treatment in CY-treated mice. We also found that a fraction of c-Kit(+) /CD45(+) HSPCs was simultaneously increased in the circulation after Rg1 treatment. Interestingly, the effects of Rg1 on the elevation of HSPCs in bone marrow and in the peripheral blood were suppressed in CY-treated splenectomized mice. These results demonstrated that Rg1 improves myelosuppression induced by CY through its action on the proliferation of HSPCs in EMH of the spleen and migration of HSPCs from the spleen to the bone marrow. © 2015 The Authors.

    To investigate potential prognostic factors affecting patient outcomes and to evaluate the optimal methods and effects of radiotherapy (RT) in the management of extramedullary plasmacytoma (EMP). Data from 55 patients with EMP between November 1999 and August 2015 were collected. The median age was 51 (range, 22-77) years. The median tumor size was 3.5 (range, 1.0-15.0) cm. The median applied dose was 50.0 (range, 30.0-70.0) Gy. Thirty-nine patients (70.9%) presented with disease in the head or neck region. Twelve patients received RT alone, 9 received surgery (S) alone, 3 received chemotherapy (CT) alone, and 3 patients did not receive any treatment. Combination therapies were applied in 28 patients. The median follow-up duration was 56 months. The 5-year local recurrence-free survival (LRFS), multiple myeloma-free survival (MMFS), progression-free survival (PFS) and overall survival (OS) rates were 79.8%, 78.6%, 65.2% and 76.0%, respectively. Univariate analysis revealed that RT was a favourable factor for all examined endpoints. Furthermore, head and neck EMPs were associated with superior LRFS, MMFS and PFS. Tumor size <4 cm was associated with superior MMFS, PFS and OS; serum M protein negativity was associated with superior MMFS and PFS; age ≥50 years and local recurrence were associated with poor MMFS. The dose ≥45 Gy group exhibited superior 5-year LRFS, MMFS and PFS rates (94.7%, 94.4%, 90.0%, respectively), while the corresponding values for the dose <45 Gy group were 62.5% (P=0.008), 53.3% (P=0.036) and 41.7% (P<0.001). Involved-site RT of at least 45 Gy should be considered for EMP. Furthermore, patients with head and neck EMP, tumor size <4 cm, age <50 years and serum M protein negativity had better outcomes.

    The Relapse Assessment for Schizophrenia Patients (RASP) was developed as a six-question self-report screener that measures indicators of Increased Anxiety and Social Isolation to assess patient stability and predict imminent relapse. This paper describes the development and psychometric characteristics of the RASP. The RASP and Positive and Negative Syndrome Scale (PANSS) were administered to patients with schizophrenia (n=166) three separate times. Chart data were collected on a subsample of patients (n=81). Psychometric analyses of RASP included tests of reliability, construct validity, and concurrent validity of items. Factors from RASP were correlated with subscales from PANSS (sensitivity to change and criterion validity [agreement between RASP and evidence of relapse]). Test-retest reliability returned modest to strong agreement at the item level and strong agreement at the questionnaire level. RASP showed good item response curves and internal consistency for the total instrument and within each of the two subscales (Increased Anxiety and Social Isolation). RASP Total Score and subscales showed good concurrent validity when correlated with PANSS Total Score, Positive, Excitement, and Anxiety subscales. RASP correctly predicted relapse in 67% of cases, with good specificity and negative predictive power and acceptable positive predictive power and sensitivity. The reliability and validity data presented support the use of RASP in settings where addition of a brief self-report assessment of relapse risk among patients with schizophrenia may be of benefit. Ease of use and scoring, and the ability to administer without clinical supervision allows for routine administration and assessment of relapse risk.

    Full Text Available Abstract Backgroud Extramedullary hematopoiesis (EMH is defined as the presence of hematopoietic stem cells such as erythroid and myeloid lineage plus megakaryocytes in extramedullary sites like liver, spleen and lymph nodes and is usually associated with either bone marrow or hematological disorders. Mammary EMH is a rare condition either in human and veterinary medicine and can be associated with benign mixed mammary tumors, similarly to that described in this case. Case presentation Hematopoietic stem cells were found in a benign mixed mammary tumor of a 7-year-old female mongrel dog that presents a nodule in the left inguinal mammary gland. The patient did not have any hematological abnormalities. Cytological evaluation demonstrated two distinct cell populations, composed of either epithelial or mesenchymal cells, sometimes associated with a fibrillar acidophilic matrix, apart from megakaryocytes, osteoclasts, metarubricytes, prorubricytes, rubricytes, rubriblasts, promyelocytes, myeloblasts. Histological examination confirmed the presence of an active hematopoietic bone marrow within the bone tissue of a benign mammary mixed tumor. Conclusions EMH is a rare condition described in veterinary medicine that can be associated with mammary mixed tumors. It's detection can be associated with several neoplastic and non-neoplastic mammary lesions, i.e. osteosarcomas, mixed tumors and bone metaplasia.

    Objective Failure to maintain abstinence despite incurring severe harm is perhaps the key defining feature of addiction.

    Failure to maintain abstinence despite incurring severe harm is perhaps the key defining feature of addiction. Relapse prevention strategies have been developed to attenuate this propensity to relapse, but predicting who will, and who will not, relapse has stymied attempts to more efficiently tailor treatments according to relapse risk profile. Here we examine the psychometric properties of a promising relapse risk measure-the Advance WArning of RElapse (AWARE) scale (Miller & Harris, 2000) in an understudied but clinically important sample of young adults.

    With this symposium, we focused on the relapse of tuberculosis in Japan. Out of 19,893 tuberculosis patients registered in 2007 in Japan, 7.48% were classified as relapse cases. Relapse cases have the risk of acquired drug resistance. But we have few analyses of the proportion of relapse tuberculosis cases with standard short course regimens for six months, factors contributing to tuberculosis relapse and the proportion of drug resistance among relapse TB cases in Japan. Therefore we analyzed the relapse tuberculosis cases in two rural areas and three urban areas. We also analyzed the proportion of drug resistance among relapse cases with the data of drug susceptibility survey of Ryoken. 1. Research of relapse tuberculosis cases: Makoto TOYOTA (Kochi City Public Health Center). To clarify the relapse rate and factors contributing to tuberculosis relapse, we investigated the relapse tuberculosis cases in the municipality where the proportion of elderly tuberculosis patients was high. Out of 902 tuberculosis patients registered in Kochi City Public Health Center during 10 years, 20 pulmonary tuberculosis patients were confirmed relapse cases with initial registered records. Pretreatment cavitations, sputum culture positivity at 2 months, medical miss-management (e.g. number of doses, duration of therapy) and poor adherence were considered to be factors contributing to tuberculosis relapse. Out of 20 relapse cases, 12 cases were detected with symptoms, while only 3 cases were detected by examination in law. 2. A clinical study on relapse cases of pulmonary tuberculosis: Shuichi TAKIKAWA (National Hospital Organization Nishibeppu National Hospital). The relapse of pulmonary tuberculosis was investigated. In the cases with a treatment history before short course chemotherapy, drug resistance rate was high, and thus it needs to be cautious of drug resistance at the time of the retreatment. In the cases with a treatment history of short course chemotherapy, relapse cases

    Macrophages have been shown to play a role in acetaminophen (APAP)-induced hepatotoxicity, contributing to both pro- and anti-inflammatory processes. In these studies, we analyzed the role of the spleen as an extramedullary source of hepatic macrophages. APAP administration (300 mg/kg, i.p.) to control mice resulted in an increase in CD11b + infiltrating Ly6G + granulocytic and Ly6G − monocytic cells in the spleen and the liver. The majority of the Ly6G + cells were also positive for the monocyte/macrophage activation marker, Ly6C, suggesting a myeloid derived suppressor cell (MDSC) phenotype. By comparison, Ly6G − cells consisted of 3 subpopulations expressing high, intermediate, and low levels of Ly6C. Splenectomy was associated with increases in mature (F4/80 + ) and immature (F4/80 − ) pro-inflammatory Ly6C hi macrophages and mature anti-inflammatory (Ly6C lo ) macrophages in the liver after APAP; increases in MDSCs were also noted in the livers of splenectomized (SPX) mice after APAP. This was associated with increases in APAP-induced expression of chemokine receptors regulating pro-inflammatory (CCR2) and anti-inflammatory (CX3CR1) macrophage trafficking. In contrast, APAP-induced increases in pro-inflammatory galectin-3 + macrophages were blunted in livers of SPX mice relative to control mice, along with hepatic expression of TNF-α, as well as the anti-inflammatory macrophage markers, FIZZ-1 and YM-1. These data demonstrate that multiple subpopulations of pro- and anti-inflammatory cells respond to APAP-induced injury, and that these cells originate from distinct hematopoietic reservoirs. - Highlights: • Multiple inflammatory cell subpopulations accumulate in the spleen and liver following acetaminophen (APAP) intoxication. • Splenectomy alters liver inflammatory cell populations responding to APAP. • Inflammatory cells accumulating in the liver in response to APAP originate from the spleen and the bone marrow. • Hepatotoxicity is reduced in

    Relapses represent one of the main problems of schizophrenia management. This article reviews the clinical factors associated with schizophrenia relapse. A research of the last 22 years of literature data was performed. Two-hundred nineteen studies have been included. Three main groups of factors are related to relapse: factors associated with pharmacological treatment, add-on psychotherapeutic treatments and general risk factors. Overall, the absence of a maintenance therapy and treatment with first generation antipsychotics has been associated with higher risk of relapse. Further, psychotherapy add-on, particularly with cognitive behaviour therapy and psycho-education for both patients and relatives, has shown a good efficacy for reducing the relapse rate. Among general risk factors, some could be modified, such as the duration of untreated psychosis or the substance misuse, while others could not be modified as male gender or low pre-morbid level of functioning. Several classes of risk factors have been proved to be relevant in the risk of relapse. Thus, a careful assessment of the risk factors here identified should be performed in daily clinical practice in order to individualise the relapse risk for each patient and to provide a targeted treatment in high-risk subjects.

    Metaplastic carcinoma of the breast is a rare tumor. The appearance of unexpected mesenchymal elements within the epithelial tumors is the squamous metaplasia. These tumors have a different clinical behaviour that classical breast carcinoma. We present a case of metaplastic mammary carcinoma with multiple relapses treated with a combination of chemotherapy and radiotherapy. The use of chemotherapy after local treatment has enhanced the relapse-free survival. The combined treatment modality seems to produce some benefit in the management of the local relapses of this neoplasms

    To assess the prevalence and characteristics of airway involvement in relapsing polychondritis (RP). Retrospective chart review and data analysis of RP patients seen in the Rheumatology Clinic and the Complex Airway Center at Beth Israel Deaconess Medical Center from January 2004 through February 2008. RP was diagnosed in 145 patients. Thirty-one patients had airway involvement, a prevalence of 21%. Twenty-two patients were women (70%), and they were between 11 and 61 years of age (median age, 42 years) at the time of first symptoms. Airway symptoms were the first manifestation of disease in 17 patients (54%). Dyspnea was the most common symptom in 20 patients (64%), followed by cough, stridor, and hoarseness. Airway problems included the following: subglottic stenosis (n = 8; 26%); focal and diffuse malacia (n = 15; 48%); and focal stenosis in different areas of the bronchial tree in the rest of the patients. Twelve patients (40%) required and underwent intervention including balloon dilatation, stent placement, tracheotomy, or a combination of the above with good success. The majority of patients experienced improvement in airway symptoms after intervention. One patient died during the follow-up period from the progression of airway disease. The rest of the patients continue to undergo periodic evaluation and intervention. In this largest cohort described in the English language literature, we found symptomatic airway involvement in RP to be common and at times severe. The nature of airway problems is diverse, with tracheomalacia being the most common. Airway intervention is frequently required and in experienced hands results in symptom improvement.

    Extramedullary hematopoiesis (EMH) is a rare disorder, defined as the appearance of hematopoietic elements outside the bone marrow or peripheral blood. The most common sites of EMH are liver and spleen, but it has been documented in other organs such as the mediastinum, lymph nodes, breast, and central nervous system. EMH occurs as a compensatory mechanism for bone marrow dysfunction in severe thalassemia. We report a case of EMH presenting as a posterior mediastinal mass in a 34-year-old woman with thalassemia intermedia with chronic cough and shortness of breath on exertion. The diagnosis of EMH was confirmed by a CT-guided fine needle biopsy. All symptoms disappeared after surgical removal of the mass.

    Background Despite all the advances in the treatment of childhood acute lymphoblastic leukemia, central nervous system relapse remains an important obstacle to curing these patients. This study analyzed the incidence of central nervous system relapse and the risk factors for its occurrence in children and adolescents with acute lymphoblastic leukemia. Methods This study has a retrospective cohort design. The studied population comprised 199 children and adolescents with a diagnosis of acute lymphoblastic leukemia followed up at Hospital das Clinicas, Universidade Federal de Minas Gerais (HC-UFMG) between March 2001 and August 2009 and submitted to the Grupo Brasileiro de Tratamento de Leucemia da Infância - acute lymphoblastic leukemia (GBTLI-LLA-99) treatment protocol. Results The estimated probabilities of overall survival and event free survival at 5 years were 69.5% (± 3.6%) and 58.8% (± 4.0%), respectively. The cumulative incidence of central nervous system (isolated or combined) relapse was 11.0% at 8 years. The estimated rate of isolated central nervous system relapse at 8 years was 6.8%. In patients with a blood leukocyte count at diagnosis ≥ 50 x 109/L, the estimated rate of isolated or combined central nervous system relapse was higher than in the group with a count 50 x 109/L at diagnosis seems to be a significant prognostic factor for a higher incidence of central nervous system relapse in childhood acute lymphoblastic leukemia.

    Myelofibrosis (MF) is characterized by the constitutive mobilization of hematopoietic stem cells (HSC) and hematopoietic progenitor cells (HPC) and the establishment of extramedullary hematopoiesis. The mechanisms underlying this abnormal HSC/HPC trafficking pattern remain poorly understood. We demonstrated that both splenic and peripheral blood (PB) MF CD34(+) cells equally share a defective ability to home to the marrow, but not to the spleens, of NOD/LtSz-Prkdc(scid) mice. This trafficking pattern could not be attributed to discordant expression of integrins or chemokine receptors other than the downregulation of C-X-C chemokine receptor type 4 by both PB and splenic MF CD34(+) cells. The number of both splenic MF CD34(+) cells and HPCs that migrated toward splenic MF plasma was, however, significantly greater than the number that migrated toward PB MF plasma. The concentration of the intact HSC/HPC chemoattractant C-X-C motif chemokine 12 (CXCL12) was greater in splenic MF plasma than PB MF plasma, as quantified using mass spectrometry. Functionally inactive truncated products of CXCL12, which are the product of proteolytic degradation by serine proteases, were detected at similar levels in both splenic and PB MF plasma. Treatment with an anti-CXCL12 neutralizing antibody resulted in a reduction in the degree of migration of splenic MF CD34(+) cells toward both PB and splenic MF plasma, validating the role of CXCL12 as a functional chemoattractant. Our data indicate that the MF splenic microenvironment is characterized by increased levels of intact, functional CXCL12, which contributes to the localization of MF CD34(+) cells to the spleen and the establishment of extramedullary hematopoiesis.

    Relapses of nephrotic syndrome often follow minor infections, commonly of the upper respiratory tract. Daily administration of maintenance prednisolone during intercurrent infections was examined to determine whether the treatment reduces relapse rates in children with frequently relapsing nephrotic syndrome. In a randomized controlled trial (nonblind, parallel group, tertiary-care hospital), 100 patients with idiopathic, frequently relapsing nephrotic syndrome eligible for therapy with prolonged low-dose, alternate-day prednisolone with or without levamisole were randomized to either receive their usual dose of alternate-day prednisolone daily for 7 days during intercurrent infections (intervention group) or continue alternate-day prednisolone (controls). Primary outcome was assessed by comparing the rates of infection-associated relapses at 12-month follow-up. Secondary outcomes were the frequency of infections and the cumulative amount of prednisolone received in both groups. Patients in the intervention group showed significantly lower infection-associated (rate difference, 0.7 episodes/patient per year; 95% confidence intervals [CI] 0.3, 1.1) and lower total relapse rates (0.9 episodes/patient per year, 95% CI 0.4, 1.4) without increase in steroid toxicity. Poisson regression, adjusted for occurrence of infections, showed that daily administration of prednisolone during infections independently resulted in 59% reduction in frequency of relapses (rate ratio, 0.41; 95% CI 0.3, 0.6). For every six patients receiving this intervention, one showed a reduction of relapse frequency to less than three per year. Daily administration of maintenance doses of prednisolone, during intercurrent infections, significantly reduces relapse rates and the proportion of children with frequently relapsing nephrotic syndrome.

    Relapse in psychiatric disorders is highly distressing, costly and engenders burn-out syndrome among mental-health workers. To study the socio-economic factors associated with relapse in individual admitted with psychiatric disorders and the pattern of socio-economic impact of relapse in those groups. A cross-sectional survey of all relapsed patients without cognitive deficit admitted into the federal Neuro-Psychiatric Hospital, Lagos, Nigeria between June and October 2007 was conducted using a self-validated Structured Interview Schedule (Relapse Socio-economic Impact Interview Schedule) and Key Informant Interview Guide. Secondary data were elicited from the patient folders, case notes, ward admission registers and nominal rolls. Data were summarised using mean, standard deviation, frequency and percentiles. Pearson's moment correlation coefficient was used to test the association among variables. The Mann-Whitney U-test was used to compare the pre-morbid and the post-morbid states. This study involved 102 respondents. Their mean age was 36.5 ± 9.8 years, mainly of male gender (72.5%) suffering from schizophrenic disorder (37.8%). Relapse and re-admission ranged between 2 and 12. Unemployment rate, marital separation and divorce increased more than 5-fold from pre-morbid to morbid states. Few (4.9%) could still settle their hospital/drug bills on their own, while most (95.1%) depended on family, philanthropist and government/waivers to pay for their bills. Their social relationships were negatively influenced with most of them expressing social isolation and low quality of life. There were significant relationships (Peconomic status, employment status and marital status of the respondents between the pre-morbid and post-morbid periods. The illness significantly affected the emotional status of the participants. Relapse and readmission in psychiatric patients have a negative impact on socio-economic well-being of patients, family and the society. Efforts should

    Extramedullary hematopoiesis is the proliferation of hematopoietic cells outside bone marrow secondary to marrow hematopoiesis failure. Extramedullary hematopoiesis rarely presents as a mass-forming hepatic lesion; in this case, imaging-based differentiation from primary and metastatic hepatic neoplasms is difficult, often leading to biopsy for definitive diagnosis. We report a case of tumefactive hepatic extramedullary hematopoiesis in the setting of myelodysplastic syndrome with concurrent hepatic iron overload, and the role of T2*-weighted gradient-echo magnetic resonance imaging in differentiating extramedullary hematopoiesis from primary and metastatic hepatic lesions. To the best of our knowledge, T2*-weighted gradient-echo evaluation of extramedullary hematopoiesis in the setting of diffuse hepatic hemochromatosis has not been previously described. A 52-year-old white man with myelodysplastic syndrome and marrow fibrosis was found to have a 4 cm hepatic lesion on ultrasound during workup for bone marrow transplantation. Magnetic resonance imaging revealed diffuse hepatic iron overload and non-visualization of the lesion on T2* gradient-echo sequence suggesting the presence of iron deposition within the lesion similar to that in background hepatic parenchyma. Subsequent ultrasound-guided biopsy of the lesion revealed extramedullary hematopoiesis. Six months later, while still being evaluated for bone marrow transplant, our patient was found to have poor pulmonary function tests. Follow-up computed tomography angiogram showed a mass within his right main pulmonary artery. Bronchoscopic biopsy of this mass once again revealed extramedullary hematopoiesis. He received radiation therapy to his chest. However, 2 weeks later, he developed mediastinal hematoma and died shortly afterward, secondary to respiratory arrest. Mass-forming extramedullary hematopoiesis is rare; however, our report emphasizes that it needs to be considered in the initial differential

    Neuropathy is a common adverse effect of bortezomib. Isolated central nervous system (CNS) relapse in MM remains exceedingly rare and carries a dismal prognosis. We present an unusual case of bortezomib related neuropathy masking a CNS relapse of MM. A 57-year-old female was diagnosed with standard-risk MM with clinical and cytogenetic features not typically associated with CNS involvement. She was treated with 4 cycles of bortezomib/cyclophosphamide/dexamethasone (VCD) and achieved a VGPR, after which she underwent an autologous stem cell transplant (ASCT) followed by bortezomib maintenance. Six months after ASCT she developed symptoms suggestive of peripheral neuropathy which was attributed to bortezomib. However the symptoms persisted despite discontinuation of bortezomib. Imaging and cerebrospinal fluid analysis subsequently confirmed a CNS relapse. CNS involvement in MM (CNS-MM) is uncommon and is considered an aggressive disease. Recently published literature has reported biomarkers with prognostic potential. However, isolated CNS relapse is even less common; an event which carries a very poor prognosis. Given the heterogeneous neurologic manifestations associated with MM, clinical suspicion may be masked by confounding factors such as bortezomib-based therapy. The disease may further remain incognito if the patient does not exhibit any of the high risk features and biomarkers associated with CNS involvement. In the era of proteasome inhibitor (PtdIns)/immunomodulator (IMID)-based therapy for MM which carries neurologic adverse effects, it is prudent to consider CNS relapse early. This case further highlights the need for more robust biomarkers to predict CNS relapse and use of newer novel agents which demonstrate potential for CNS penetration.

    We report a role for Borrelia microti as a cause of relapsing fever in Iran supported by robust epidemiological evidence. The molecular identity of this spirochete and its relation with other relapsing fever borreliae have, until now, been poorly delineated. We analyzed an isolate of B. microti, obtained from Ornithodoros erraticus ticks, by sequencing four loci (16S rRNA, flaB, glpQ, intragenic spacer [IGS]) and comparing these sequences with those of other relapsing fever borreliae. Phylogenetic analysis using concatenated sequences of 16S rRNA, flaB, and glpQ grouped B. microti alongside three members of the African group, B. duttonii, B. recurrentis, and B. crocidurae, which are distinct from B. persica, the most prevalent established cause of tick-borne relapsing fever in Iran. The similarity values for 10 concatenated sequences totaling 2,437 nucleotides ranged from 92.11% to 99.84%, with the highest homologies being between B. duttonii and B. microti and between B. duttonii and B. recurrentis. Furthermore, the more discriminatory IGS sequence analysis corroborated the close similarity (97.76% to 99.56%) between B. microti and B. duttonii. These findings raise the possibility that both species may indeed be the same and further dispel the one-species, one-vector theory that has been the basis for classification of relapsing fever Borrelia for the last 100 years.

  9. Gender differences in alcohol and substance use relapse.

    This review explores gender differences in relapse and characteristics of relapse events in alcohol and substance use. For alcohol, relapse rates were similar across gender. Although negative mood, childhood sexual abuse, alcohol-related self-efficacy, and poorer coping strategies predicted alcohol relapse, gender did not moderate these effects. Gender did moderate the association between marriage and alcohol relapse. For women, marriage and marital stress were risk factors for alcohol relapse; among men, marriage lowered relapse risk. This gender difference in the role of marriage in relapse may be a result of partner differences in problem drinking. Alcoholic women are more likely to be married to heavy drinking partners than are alcoholic men; thus, alcoholic women may be put at risk of relapse by marriage and alcoholic men may be protected by marriage. There are fewer studies documenting gender differences in substance abuse relapse so conclusions are limited and tentative. In contrast to the lack of gender differences in alcohol relapse rates, women appear less likely to experience relapse to substance use, relative to men. Women relapsing to substance use appear to be more sensitive to negative affect and interpersonal problems. Men, in contrast, may be more likely to have positive experiences prior to relapse.

    Full Text Available Relapse in multiple sclerosis (MS is defined as a neurologic deficit associated with an acute inflammatory demyelinating event that lasts at least 24 hours in the absence of fever and infection. Myelinoclasis and axonal transection occur in relapses. Diagnosis, prognosis, treatment, and many other features of the disease are directly related to the relapses. MS starts as the relapsing-remitting (RRMS form in 85% of patients. A large number of relapses in the first years, polysymptomatic relapses, and pyramidal system, brain stem, and spinal cord involvement are signs of a poor outcome. The average frequency of relapses is approximately one per year during the first years of RRMS. The frequency of relapses increases during systemic infections, psychological stress, and in the postpartum first 3 months. Seventy-five percent of relapses are monosymptomatic. Pseudo-relapses and paroxysmal symptoms are distinguished from relapses by their sudden onset, sudden termination, and shorter duration. Contrast enhancement is valuable in imaging, but undetectable in most relapses. The regression in the first few weeks of relapses is explained by reduction of the edema, and by remyelination in the following months. Relapses and their features are also among the main determinants of treatment. High-dose methylprednisolone and early treatment with adrenocorticotropic hormone reduce post-relapse disability and shorten the duration of relapses. Plasmapheresis is a good option for patients who do not respond to steroid treatment. Identification of relapses by patients and physicians, distinguishing them from imitators, proper evaluation, treatment when necessary, and monitoring the results are of great importance for patients with MS. The educational levels of patients and physicians regarding these parameters should be increased. Well-designed studies that evaluate the long-term effect of relapse treatment on disability are needed.

    Full Text Available We present a clinical case of parathyroid cancer in a patient with relapsing secondary hyperparathyroidism at 4 years after subtotal parathyroidectomy. Its unique character is related to the combination of relapsing secondary hyperparathyroidism, parathyromatosis, ectopic of an adenomatous hyperplastic parathyroid gland into the thyroid gland, and parathyroid cancer. Several most complicated aspects of parathyroid surgery are disclosed, such as the choice of strategy for surgical intervention in secondary hyperparathyroidism, complexity of morphological and cytological diagnostics of this disorder.

    Full Text Available Damiano Paolicelli, Vita Direnzo, Maria TrojanoDepartment of Neurological and Psychiatric Sciences, University of Bari, Bari, ItalyAbstract: Multiple sclerosis (MS is the most common autoimmune illness of the central nervous system. For many years the inflammatory manifestations of MS were treated using only corticosteroids. Since the 1990s the results of several clinical trials with immunomodulatory agents have changed the therapeutic approach to this disease. Interferon beta (IFNβ-1b represents the pioneer of those therapies. There is growing evidence from clinical trials on relapsing-remitting MS and clinically isolated syndromes suggestive of MS that IFNβ-1b reduces the frequency and severity of relapses and the development of new and active brain lesions as assessed by magnetic resonance imaging. Long-term data suggest a persistent efficacy of IFNβ-1b on disease activity and a positive effect in slowing disability worsening. Furthermore a reduction of relapse rate and a slight positive effect on the progression were demonstrated when IFNβ-1b was administered to still-active secondary progressive MS. IFNβ-1b therapy is well tolerated and relatively free of long-term side effects. In spite of the emergence of new agents for the treatment of MS, IFNβ-1b still remains a first-line therapy with a fundamental role in all stages of the disease.Keywords: interferon beta-1b, relapsing-remitting multiple sclerosis, clinically isolated syndromes, efficacy, safety, neutralizing antibodies

    Three relapse cases were reported out of 107 hospital-attending typhoid cases within a period of 2 years (2014-2016) from Apollo Gleneagles Hospital, Kolkata, India. During the first episode of typhoid fever, 2 of the 3 cases were treated with ceftriaxone (CRO) for 7 days, and 1 was treated for 14 days. Six Salmonella Typhi (S. Typhi) isolates, obtained from the 3 patients during both typhoid episodes, were subjected to antimicrobial susceptibility testing, detection of quinolone resistance-determining region (QRDR) mutation and molecular subtyping by pulsed-field gel electrophoresis (PFGE), multiple-locus variable number tandem repeat analysis (MLVA), multilocus sequence typing (MLST), clustered regularly interspaced short palindromic repeats (CRISPR), and H58 haplotyping. Pairs of the S. Typhi strains isolated from two of the patients during the 1st and 2nd episodes were similar with respect to the antimicrobial resistance (AMR) profiles, QRDR mutations, and molecular subtypes; whereas, the S. Typhi strain pair isolated from the 3rd patient were different in their AMR profiles, QRDR mutations, and MLVA profiles. From these observations, it may be concluded that in spite of treating typhoid cases with CRO for 7-14 days, relapse of typhoid fever might occur. The article also showed the advantage of MLVA typing over PFGE, MLST, and CRISPR typing for the discrimination of strains isolated from the same patient in case of relapse of typhoid fever.

    Addiction is characterised by cycles of compulsive drug taking, periods of abstinence and episodes of relapse. The extinction/reinstatement paradigm has been extensively used in rodents to model human relapse and explore underlying mechanisms and therapeutics. However, relapse to drug seeking behaviour has not been previously demonstrated in invertebrates. Here, we used a cocaine conditioned place preference (CPP) paradigm in the flatworm, planarian, followed by extinction and reinstatement of drug seeking. Once baseline preference was established for one of two distinctly textured environments (i.e. compartments with a coarse or smooth surface), planarian received pairings of cocaine (5μM) in the non-preferred, and vehicle in the most preferred, environment, and were tested for conditioning thereafter. Cocaine produced robust CPP, measured as a significant increase in the time spent in the cocaine-paired compartment. Subsequently, planarian underwent extinction training, reverting back to their original preference within three sessions. Brief exposure to cocaine (5μM) or methamphetamine (5μM) reinstated cocaine-seeking behaviour. By contrast, the high affinity dopamine transporter inhibitor, (N-(n-butyl)-3α-[bis (4-fluorophenyl) methoxy]-tropane) (JHW007), which in rodents exhibits a neurochemical and behavioural profile distinct from cocaine, was ineffective. The present findings demonstrate for the first time reinstatement of extinguished cocaine seeking in an invertebrate model and suggest that the long-term adaptations underlying drug conditioning and relapse are highly conserved through evolution.

    Full Text Available Background: Despite the effectiveness of pharmacotherapy in acute phase of bipolar mood disorder, patients often experience relapses or recurrent episodes. Hospitalization of patients need a great deal of financial and humanistic resources which can be saved through understanding more about the rate of relapse and factors affecting this rate. Methods: In a descriptive analytical study, 380 patients with bipolar disorder who were hospitalized in psychiatric emergency ward of Noor hospital, Isfahan, Iran, were followed. Each patient was considered for; the frequency of relapse and recurrence, kind of pharmachotherapy, presence of psychotherapeutic treatments, frequency of visits by psychiatrist and the rank of present episode. Results: The overall prevalence of recurrence was 42.2%. Recurrence was lower in patients using lithium carbonate or sodium valproate or combined therapy (about 40%, compared to those using carbamazepine (80%. Recurrence was higher in patients treated with only pharmacotherapy (44.5% compared to those treated with both pharmacotherapy and psychotherapy (22.2%. Patients who were visited monthy by psychiatrist had lower rate of recurrence compared to those who had irregular visits. Conclusion: The higher rate of recurrence observed in carbamazepine therapy may be due to its adverse reactions and consequently poor compliance to this drug. Lower rates of recurrence with psychotherapy and regular visits may be related to the preventive effects of these procedures and especially to the effective management of stress.

    Full Text Available This retrospective study was to determine if patient-specific instrumentation (PSI for total knee arthroplasty (TKA leads to shortened surgical time through increased operating room efficiency according to different tibial PSI designs. 166 patients underwent primary TKA and were categorized into three groups as follows: PSI without extramedullary (EM tibial guide (group 1, n=48, PSI with EM tibial guide (group 2, n=68, and conventional instrumentation (CI group (group 3, n=50. Four factors were compared between groups, namely, operative room time, thickness of bone resection, tibial slope, and rotation of the component. The mean surgical time was significantly shorter in the PSI with EM tibial guide group (group 2, 63.9±13.6 min compared to the CI group (group 3, 82.8±24.9 min (P<0.001. However, there was no significant difference in the PSI without EM tibial guide group (group 1, 75.3±18.8 min. This study suggests that PSI incorporating an EM tibial guide may lead to high operative efficiency in TKA compared to CI. This trial is registered with KCT0002384.

    Current schemes for treatment of immune-mediated hearing loss with sporadic short-course, low-dose corticosteroids, are insufficient. To determine the role of azathioprine in the control of auditory impairment, a longitudinal, observational, descriptive study was performed with 20 patients treated with azathioprine (1.5-2.5mg/kg/day into two doses) for 1year. The loss of 10dB on two consecutive frequencies or 15dB on an isolated frequency was considered as relapse. The mean age of the patients was 52.50years (95%CI: 46.91-58.17), half were women. Bilateral affectation was 65%. 75% had organ specific disease and 25% had systemic autoimmune disease. The difference between baseline PTA (46.49dB; DS18.90) and PTA at 12months (45.47dB; DS18.88) did not reach statistical significance (P=.799). There was a moderate positive correlation between female sex and the presence of systemic disease (R=.577). By applying Student's t for paired data, a significant difference (P=.042) was obtained between the PTA in frequencies up to 1000 Hz (PTA125-1000Hz). The relative incidence rate of relapse per year was .52 relapses/year (95%CI: .19-1.14]). The median time to audiometric relapse-free was 9.70months (DS1.03). Azathioprine maintains the hearing threshold, decreases the risk of relapse, and slows down the rate at which patients relapse, altering the course of immune-mediated inner ear disease.

    Despite the success of central nervous system (CNS) directed therapy in pediatric acute lymphoblastic leukemia (ALL), relapse involving the CNS continues to be observed in 5-10% of children when utilizing standard intrathecal prophylactic chemotherapy. While most pediatric ALL treatment protocols mandate regular lumbar punctures (LP) for the intrathecal injection of chemotherapy, the value of routine cytological analysis of cerebrospinal fluid (CSF) during therapy is unknown. Our objective was to assess the diagnostic value of routine CSF analysis during ALL therapy. To allow for at least 10 years of follow up from ALL diagnosis, children (0-18 years) with ALL diagnosed and treated at SickKids, Toronto, Canada between 1994-2004 were studied. Medical records of patients with CNS relapse were examined to determine whether CNS relapse was diagnosed based on cytology of a routinely obtained CSF sample, a CSF sample obtained because of signs and symptoms or a CSF sample obtained after the diagnosis of a bone marrow relapse. Of 494 children treated for ALL, 31 (6.6%) developed a relapse of ALL involving the CNS. Twenty-two had an isolated CNS relapse and nine had a combined bone marrow and CNS relapse. Among patients with isolated CNS relapse, 73% (16/22) were diagnosed based on routine CSF samples obtained from asymptomatic children. Conversely, 89% (8/9) of children with combined bone marrow and CNS relapse presented with symptoms and signs that prompted CSF examination. Routine CSF examination at the time of LP for intrathecal chemotherapy is useful in detecting CNS relapse. © 2014 Wiley Periodicals, Inc.

    It is important to highlight that attempts at understanding and explaining addiction have been made for centuries. It is, however, just five decades ago, with the growth of science and technology that more interest has been observed in this field. This chapter examines different views and theories that have been posited to understand and explain addiction. More attention will be given to prominent views that seem to draw consensus among researchers and medical practitioners. The first section of the chapter introduces the addiction debate, the different theories that have been provided to explain it from different perspectives and disciplines such as neurosciences, philosophy and psychology. Then, the chapter discusses different views on the role of relapse and what it entails in understanding addiction. The second section discusses different proposed and used forms of treating addiction. Thus, the chapter discusses the received view of addiction, the understanding of relapse as a critical element in addiction and treatments.

    Full Text Available Relapse among abstinent drug users is normal. Several factors are related to relapse, but it remains unclear what individuals' actual life circumstances are during periods of abstinence, and how these circumstances facilitate or prevent relapse.To illuminate drug users' experiences during abstinence periods and explore the real-life catalysts and inhibitors contributing to drug use relapse.Qualitative in-depth interviews were conducted with 20 drug users recruited from a compulsory isolated drug rehabilitation center in Changsha. The interviews were guided by open-ended questions on individuals' experiences in drug use initiation, getting addicted, treatment history, social environment, abstinence, and relapse. Participants were also encouraged to share their own stories. Interviews were digitally recorded and fully transcribed. The data of 18 participants who reported abstinence experiences before admission were included in the analyses. The data were analyzed using a thematic analysis with inductive hand coding to derive themes.Most drug users were able to successfully abstain from drugs. During abstinence, their lives were congested with challenges, such as adverse socioeconomic conditions, poor family/social support, interpersonal conflicts, and stigma and discrimination, all of which kept them excluded from mainstream society. Furthermore, the police's system of ID card registration, which identifies individuals as drug users, worsened already grave situations. Relapse triggers reported by the participants focused mainly on negative feelings, interpersonal conflicts, and stressful events. Craving was experienced but not perceived as a relapse trigger by most participants.This study of in-depth interview with drug users found evidence of situations and environments they live during abstinence appear rather disadvantaged, making it extremely difficult for them to remain abstinent.

    The purpose of this study, which involved 240 acute leukemia patients (ALL: 115, ANL: 125) who received an allogeneic bone marrow transplantation (BMT) with preconditioning by total body irradiation (TBI) and chemotherapy, was to examine retrospectively the TBI factors that may have influenced a leukemic relapse. The patients were divided into two groups: 124 patients who had received their BMT within a diagnosis-transplantation period of 9 months or less (DTP9 group), and 116 patients who had received their BMT within a diagnosis-transplantation period of 10 months or more (DTP10 group). It was concluded that: (1) the higher the TBI dose, the fewer the relapse rates in DTP9 group; (2) the longer the TBI period, the greater the increase in the relapse rate in DTP10 group. It was thus speculated that an effective TBI regimen for acute leukemia patients may vary depending on the length of time that has elapsed from the diagnosis of leukemia to the BMT. (author)

    IGF2 is a tumor suppressor gene at locus 11p15. Many hepatoblastomas have loss of heterozygosity (LOH) at this locus. Earlier studies have not demonstrated any association between LOH and prognosis. Aim of the study was to evaluate the prognostic significance of LOH at 11p15.5 in hepatoblastomas. DNA was isolated from normal liver and tumor tissue in 20 patients with hepatoblastoma. PCR was performed and cases were classified as LOH present, absent or non-informative. Patients' follow-up data was analyzed using Fischer's exact test and Kaplan-Meier survival analysis for relapse-free survival (RFS) in relation to LOH. Ethical clearance was obtained from the institutional ethics board. All cases were informative for at least one microsatellite marker used. 4 of the 20 cases (20%) had LOH at 11p15.5. One patient died in the immediate postoperative period. 5 of 19 patients relapsed (26%). Of 4 patients who had LOH, 3 (75%) relapsed, the time to relapse being 7, 7 and 9 months, respectively. Of the 15 cases without LOH, 2 (13.3%) relapsed. 4 patients had mixed epithelial and mesenchymal histology; 3 of them had LOH. The 2 groups with and without LOH were well matched. The RFS for patients with LOH (n=4) was 13% (mean survival time [MST]: 8.7 months; 95CI 6.7-10.7), while the RFS for cases without LOH (n=15) was 75% (MST: 100.7 months; 95CI 74.5-126.8). Mixed epithelial and mesenchymal histology is more frequently associated with LOH on chromosome 11p15.5 than pure epithelial histology. LOH on chromosome 11p15.5 is associated with a significantly increased incidence of relapse and a significantly shorter relapse-free survival in patients with hepatoblastoma. The risk of relapse is higher and the RFS lower both in standard-risk and high-risk patients with hepatoblastoma if they demonstrate the presence of LOH at 11p15.5. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available A 9-month-old female Weimaraner was presented to the emergency service due to episodes of fever and neck pain. Physical examination revealed a stiff neck posture and elevated body temperature. Shortly after clinical examination was performed, the dog developed peracute onset of non-ambulatory tetraparesis compatible with a C1–C5 spinal cord (SC lesion. Immediately thereafter (<1 h, MRI of the cervical SC was performed with a 3-T scanner. A left ventrolateral intradural-extramedullary SC compression caused by a round-shaped structure at the level of C3––C4 was evidenced. The structure was iso- to slightly hyperintense in T1-weighted (T1W sequences compared to SC parenchyma and hyperintense in T2-weighted, gradient echo, and fluid-attenuated inversion recovery. Moreover, the structure showed a strong homogeneous contrast uptake in T1W sequences. Cerebrospinal fluid (CSF analysis revealed a mixed pleocytosis, as well as elevated protein and erythrocyte count. Early-stage hyperacute extramedullary hemorrhage was suspected due to immune mediated vasculitis. The dog was maintained under general anesthesia and artificial ventilation for 24 h and long-term therapy with corticosteroids and physiotherapy was initiated. Eight weeks after initial presentation, the dog was ambulatory, slightly tetraparetic. Follow-up MRI showed a regression of the round-shaped structure and pleocytosis was not evident in CSF analysis. This report describes an early-stage hyperacute extramedullary hemorrhage, a condition rarely recorded in dogs even in experimental settings.

  11. The effects of hematopoietic stem cell transplant on splenic extramedullary hematopoiesis in patients with myeloproliferative neoplasm-associated myelofibrosis.

    Hematopoietic stem cell transplant (HSCT) is the only curative treatment for myeloproliferative neoplasm-associated myelofibrosis (MPN-MF). The main clinical manifestation of MPN-MF is splenomegaly secondary to extramedullary hematopoiesis (EMH). The effects of HSCT on splenic EMH and associated vascular and stromal changes are unknown. This study compares the findings seen in spleens following HSCT with those of nontransplanted patients, normal controls, and matched bone marrow (BM) samples. This study included three transplanted MPN-MF spleens, three nontransplanted MPN-MF spleens, and three normal controls. Spleens were assessed for: (a) presence/extent of EMH; (b) presence of Gamna-Gandy bodies; (c) splenic fibrosis; (d) CD34-positive microvessel density; (e) CD8-positive sinusoids; (f) frequency of smooth muscle actin-positive myoid cells; and (g) nerve growth factor receptor-positive adventitial reticulum cells. In two cases, matched BM samples were assessed for cellularity, presence of atypical megakaryocytes, and fibrosis. Compared with normal controls, all MPN-MF spleens were larger in size, had EMH, red pulp fibrosis, higher CD34-positive microvessel density, and decreased CD8-positive sinusoids. Compared with nontransplanted cases, post-HSCT spleens showed disappearance or reduction of EMH. Gamna-Gandy bodies were increased; no differences in the remaining parameters were found. A reduction of splenic EMH was associated with normalization of BM cellularity and megakaryopoiesis. HSCT reduces/abrogates splenic EMH and is associated with an increased number of Gamna-Gandy bodies, which may suggest vascular damage. The lack of stromal changes in spleens removed shortly after transplant is in line with similar observations in the BM, where a longer interval is often necessary for resolution of fibrosis.

    Purpose: The purpose of this study was to elucidate the efficacy and optimal method of radiotherapy in the management of solitary extramedullary plasmacytoma occurring in the head and neck regions (EMPHN). Methods and Materials: Sixty-seven patients (43 male and 24 female) diagnosed with EMPHN between 1983 and 2008 at 23 Japanese institutions were reviewed. The median patient age was 64 years (range, 12–83). The median dose administered was 50 Gy (range, 30–64 Gy). Survival data were calculated by the Kaplan-Meier method. Results: The median follow-up duration was 63 months. Major tumor sites were nasal or paranasal cavities in 36 (54%) patients, oropharynx or nasopharynx in 16 (23%) patients, orbita in 6 (9%) patients, and larynx in 3 (5%) patients. The 5- and 10-year local control rates were 95% and 87%, whereas the 5- and 10-year disease-free survival rates were 56% and 54%, respectively. There were 5 (7.5%), 12 (18%), and 8 (12%) patients who experienced local failure, distant metastasis, and progression to multiple myeloma, respectively. In total, 18 patients died, including 10 (15%) patients who died due to complications from EMPHN. The 5- and 10-year overall survival (OS) rates were 73% and 56%, respectively. Radiotherapy combined with surgery was identified as the lone significant prognostic factor for OS (p = 0.04), whereas age, gender, radiation dose, tumor size, and chemotherapy were not predictive. No patient experienced any severe acute morbidity. Conclusions: Radiotherapy was quite effective and safe for patients with EMPHN. Radiotherapy combined with surgery produced a better outcome according to survival rates. These findings require confirmation by further studies with larger numbers of patients with EMPHN.

    Relapses (episodic exacerbations of neurological signs or symptoms) are a defining feature of relapsing-remitting multiple sclerosis (MS), the most prevalent MS phenotype. While their diagnostic value relates predominantly to the definition of clinically definite MS, their prognostic value is determined by their relatively high associated risk of incomplete remission resulting in residual disability. The mechanisms governing a relapse incidence are unknown, but numerous modifiers of relapse risk have been described, including demographic and clinical characteristics, many of which represent opportunities for improved disease management. Also relapse phenotypes have been associated with patient and disease characteristics and an individual predisposition to certain phenotypic presentations may imply individual neuroanatomical disease patterns. While immunomodulatory therapies and corticosteroids represent the mainstay of relapse prevention and acute management, respectively, their effect has only been partial and further search for more efficient relapse therapies is warranted. Other areas of research include pathophysiology and determinants of relapse incidence, recurrence and phenotypes, including the characteristics of the relapsing and non-relapsing multiple sclerosis variants and their responsiveness to therapies. © 2015 S.

    Full Text Available Increased availability of Next Generation Sequencing (NGS techniques allows, for the first time, to distinguish relapses from reinfections in patients with multiple Buruli ulcer (BU episodes.We compared the number and location of single nucleotide polymorphisms (SNPs identified by genomic screening between four pairs of Mycobacterium ulcerans isolates collected at the time of first diagnosis and at recurrence, derived from a collection of almost 5000 well characterized clinical samples from one BU treatment center in Benin.The findings suggest that after surgical treatment-without antibiotics-the second episodes were due to relapse rather than reinfection. Since specific antibiotics were introduced for the treatment of BU, the one patient with a culture available from both disease episodes had M. ulcerans isolates with a genomic distance of 20 SNPs, suggesting the patient was most likely reinfected rather than having a relapse.To our knowledge, this study is the first to study recurrences in M. ulcerans using NGS, and to identify exogenous reinfection as causing a recurrence of BU. The occurrence of reinfection highlights the contribution of ongoing exposure to M. ulcerans to disease recurrence, and has implications for vaccine development.

    Full Text Available A five-year-old girl manifested with acute relapsing polyradiculo-neuropathy. Elevated cerebrospinal fluid proteins, electro-physiological evidence of conduction block and remitting course suggested possible acquired demyelinating radiculoneuropathy. However, intellectual deterioration during follow up, evidence of extensive, symmetrical and periventricular demyelination on MRI of brain and metachromatic on sural nerve biopsy led to the diagnosis of metachromatic leukodystrophy (MLD. Inherited neuropathies such as MLD may occasionally present atypically in the early stages. Recognition of this variation has considerable therapeutic and prognostic significance.

    A second SCT is generally accepted as the only potentially curative approach for ALL patients that relapse after SCT, but the role of second SCT for pediatric ALL is not fully understood. We performed a retrospective analysis of 171 pediatric patients who received a second allo-SCT for relapsed ALL after allo-SCT. OS at 2 years was 29.4 ± 3.7%, the cumulative incidence of relapse was 44.1 ± 4.0% and non-relapse mortality was 18.8 ± 3.5%. Relapse occurred faster after the second SCT than after the first SCT (117 days vs 164 days, P=0.04). Younger age (9 years or less), late relapse (180 days or more after first SCT), CR at the second SCT, and myeloablative conditioning were found to be related to longer survival. Neither acute GVHD nor the type of donor influenced the outcome of second SCT. Multivariate analysis showed that younger age and late relapse were associated with better outcomes. Our analysis suggests that second SCT for relapsed pediatric ALL is an appropriate treatment option for patients that have achieved CR, which is associated with late relapse after the first SCT.

  18. Mathematical Models of Tuberculosis Reactivation and Relapse

    Directory of Open Access Journals (Sweden)

    Robert Steven Wallis

    2016-05-01

    Full Text Available The natural history of human infection with Mycobacterium tuberculosis (Mtb is highly variable, as is the response to treatment of active tuberculosis. There is presently no direct means to identify individuals in whom Mtb infection has been eradicated, whether by a bactericidal immune response or sterilizing antimicrobial chemotherapy. Mathematical models can assist in such circumstances by measuring or predicting events that cannot be directly observed. The 3 models discussed in this review illustrate instances in which mathematical models were used to identify individuals with innate resistance to Mtb infection, determine the etiology of tuberculosis in patients treated with tumor necrosis factor antagonists, and predict the risk of relapse in persons undergoing tuberculosis treatment. These examples illustrate the power of various types of mathematic models to increase knowledge and thereby inform interventions in the present global tuberculosis epidemic.

    Objective Disease relapses are common for patients with anti-neutrophil cytoplasm antibody associated vasculitis (AAV). The role of low-dose glucocorticoids (GC) in relapse prevention is controversial. We undertook a systematic review and meta-analysis to determine if GC target doses influence relapses of AAV. Methods Medline, EMBASE and Cochrane databases were searched for observational studies and randomized controlled trials of treatment of AAV that included a predefined GC treatment plan. The association of GC target dose with the proportion of relapses in studies was assessed using meta-regression and multi-level generalized linear modeling. Results Thirteen studies (983 patients) were identified for inclusion. There were no studies directly comparing GC regimens. We classified 288 patients as having a non-zero GC target dose by study end and 695 patients as having a zero GC target dose by study end. The pooled proportion of patients with a relapse was 36% (95% confidence interval [CI] 25 to 47%). GC regimen was the most significant variable explaining the variability between the proportions of patients with relapses. The proportion of patients with a relapse was 14% (95% CI 10 to 19%) in non-zero GC target dose and 43% (95% CI 33 to 52%) in zero GC target dose studies. Differences other than GC regimens exist between studies that complicate the comparability of trials and isolation of the variability in relapses due to GC target alone. Conclusions Studies with longer courses of GC in AAV are associated with fewer relapses. These results have implications for study design and outcome assessment in clinical trials of AAV.

    2010-06-01

    We conducted a prospective follow-up study of consecutive opiate dependent patients admitted to a residential addiction treatment service for detoxification. We measured the rate of relapse following discharge, and sought to identify factors that were associated with early relapse (i.e., a return to daily opiate use). Follow-up interviews were conducted with 109 patients, of whom, 99 (91%) reported a relapse. The initial relapse occurred within one week in 64 (59%) cases. Multivariate survival analysis revealed that earlier relapse was significantly predicted by younger age, greater heroin use prior to treatment, history of injecting, and a failure to enter aftercare. Unexpectedly, those who were in a relationship with an opiate user had significantly delayed relapse. Those who completed the entire six-week inpatient treatment programme also had a significantly delayed relapse. In order to reduce relapse and the associated increased risk of fatal overdose, services providing residential opiate detoxification should prepare people for admission, strive to retain them in treatment for the full admission period and actively support their entry into planned aftercare in order to improve outcome.

  14. Extinction of relapsed fear does not require the basolateral amygdala.

    2017-03-01

    It is well established that extinguished fears are restored with the passage of time or a change in physical context. These fear restoration phenomena are believed to mimic the conditions under which relapse occurs in patients that have been treated for anxiety disorders by means of cue-exposure therapy. Here, we used a rodent model to extinguish relapsed fear and assess whether this new extinction prevents further relapse. We found that activity in the basolateral amygdala (BLA) is required to initially extinguish conditioned fear, but this activity was not necessary to subsequently extinguish relapsed fear. That is, extinction of spontaneously recovered or renewed fear was spared by BLA inactivation. Yet, this BLA-independent learning of extinction did not protect against further relapse: extinction of relapsed fear conducted without BLA activity was still likely to return after the passage of time or a shift in physical context. These findings have important clinical implications. They indicate that pharmacological agents with anxiolytic properties may disrupt initial cue-exposure therapy but may be useful when therapy is again needed due to relapse. However, they also suggest that these agents will not protect against further relapse, implying the need for developing drugs that target other brain regions involved in fear inhibition.

    One of the main aims of treatment after successful recovery from anorexia nervosa (AN) is to prevent a relapse. The Guideline Relapse Prevention (GRP) Anorexia Nervosa offers a structured approach to relapse prevention. This study explores how patients and their parents experience working with the guideline. It also describes the factors that support or hinder successful application of the guideline. A descriptive qualitative research design was chosen involving in-depth interviews with seventeen patients with anorexia nervosa and six sets of parents. Patients and family members were generally satisfied with the support provided by the GRP. It contributed significantly to a better understanding of the personal process of relapse. Patients and families valued being able to keep in touch with their professional during the aftercare programme. The GRP supports the patient's use of self-management strategies for relapse prevention. © 2018 Australian College of Mental Health Nurses Inc.

    Full Text Available Objective The study aims to investigate the presence of pain amongst multiple sclerosis (MS patients. Method One hundred MS patients responded to questionnaires evaluating neuropathic and nociceptive pain, depression and anxiety. Statistical analysis was performed using the Mann–Whitney U, Chi-Square and two-tailed Fisher’s exact tests and multivariate logistic regression. Results Women had a statistically higher prevalence of pain (p = 0.037, and chances of having pain after the age of 50 reduced. Women with pain had a statistically significant lower number of relapses (p = 0.003, restricting analysis to those patients with more than one relapse. After the second relapse, each relapse reduced the chance of having pain by 46%. Presence of pain was independent of Expanded Disability Status Scale (EDSS anxiety, and depression. Conclusion Our findings suggest a strong inverse association between relapses and pain indicating a possible protective role of focal inflammation in the control of pain.

    2014-01-01

    Despite the dramatic increase in the use of buprenorphine for the treatment of opioid dependence, clinical outcomes of this treatment approach continue to need evaluation. This study examines factors associated with relapse and retention during buprenorphine treatment in a sample of opioid dependent outpatients. In a retrospective chart review of 62 patients with opioid dependence, relapse was determined by self-report, urine toxicology screens, and by checking the state controlled substance monitoring database. Data was analyzed using two-way tests of association and logistic regression. Patients with comorbid anxiety disorders, active benzodiazepine use (contrary to clinic policy), or active alcohol abuse, were significantly more likely to relapse. Patients who relapsed were also more likely to be on a higher buprenorphine maintenance dose. This study identifies relapse risk factors during buprenorphine treatment for opioid dependence. Future research is needed to determine whether modifying these factors may lead to improved treatment outcomes. © American Academy of Addiction Psychiatry.

    Typhoid fever is a systemic illness which in high-income countries mainly affects travellers. The incidence is particularly high on the Indian subcontinent. Travellers who visit friends and relatives (VFR) have been shown to have a different risk profile than others. We wished to identify main characteristics for travellers infected with S. Typhi considering both clinical and laboratory findings in order to provide for faster and better diagnostics in the future. The outcome of treatment, especially concerning relapse, was evaluated as well. Retrospectively collected data from 19 adult cases of typhoid fever over a 5-year period at the Department of Infectious Diseases, Copenhagen University Hospital, Hvidovre Denmark. The patients were young adults, presenting with symptoms within a month after travelling. 84% were returned from travelling in the Indian subcontinent. 17 out of 19 patients were VFR-travellers. The main symptoms were fever (100%), gastrointestinal symptoms (84%), headache (58%) and dry cough (26%). Laboratory findings showed elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH) in all cases and elevated alanine transaminase (ALAT) in 47% of cases. In primary cases 4 isolates were fully susceptible to ciprofloxacin, the remaining were intermediate susceptible. Relapse occurred in 37% of the cases and only in cases where the patient was infected by a strain with intermediate susceptibility. Better pre-travel counselling should be given to VFR-travellers. The main symptoms and laboratory findings confirm previous findings. The relapse rate was unexpected high and could be correlated to ciprofloxacin-resistance.

    Diffuse marrow replacement in acute leukemia is well known, but there are few reports describing the MRI features of pediatric leukemic relapse. Our purpose was to describe the MRI appearance of pediatric leukemic relapse. A total of 53 consecutive children with a history of ALL were referred for musculoskeletal MRI from 1 January 1998 to 28 February 2007 at one center, and from 1 January 2000 to 2 May 2007 at a second center. From this group, 14 children seen at initial diagnosis of leukemia and 2 children who underwent MRI after therapy for relapse were excluded. The remaining 37 children, 8 with relapse and 29 in remission, were studied. Images of patients with relapse and in remission were reviewed for type and configuration of marrow infiltration; coexisting marrow alterations including osteonecrosis or stress reaction were also reviewed. All eight children with relapse demonstrated nodular lesions with well-defined margins. Coexisting osteonecrosis was present in three children (38%) and pathologic fracture in one. Among the 29 children in remission, 9 showed stress reaction/fracture, 14 showed osteonecrosis and 9 showed ill-defined nodules, and in 5 the marrow was completely normal. Well-defined nodules in all patients with leukemic relapse suggest that this appearance is characteristic and distinct from the published findings of diffuse marrow replacement in acute leukemia.

    1984-01-01

    Thirty-four children with acute lymphoblastic leukemia, who developed bone marrow relapse after treatment was electively stopped, received reinduction, consolidation, continuing therapy, and intrathecal (IT) methotrexate (MTX). Sixteen children who relapsed within six months of stopping treatment had a median second-remission duration of 26 weeks; all next relapses occurred in the bone marrow. In 18 children who relapsed later, the median duration of second remission was in excess of two years, but after a minimum of four years follow-up, 16 patients have so far relapsed again (six in the CNS). CNS relapse occurred as a next event in four of 17 children who received five IT MTX injections only and in two of 14 children who received additional regular IT MTX. Although children with late marrow relapses may achieve long second remissions, their long-term out-look is poor, and regular IT MTX does not afford adequate CNS prophylaxis. It remains to be seen whether more intensive chemotherapy, including high-dose chemoradiotherapy and bone marrow transplantation, will improve the prognosis in this group of patients

    Many women quit smoking during pregnancy, but relapse after the baby is born. To understand why and identify ways of preventing this, this study reviewed the qualitative literature on women's experience of postpartum smoking relapse. A systematic review of qualitative studies and process evaluations of trials. We undertook a thematic synthesis of published qualitative data. We screened 1336 papers. Twenty-two papers reporting on 16 studies were included, reporting on the views of 1031 postpartum women. Factors affecting relapse and barriers and facilitators to relapse prevention were identified around the key themes of beliefs, social influences, motivation, physiological factors and identity. Women's beliefs about smoking as a means of coping with stress and the need for social support, especially from a partner, emerged as important. Extrinsic motivation to quit during the pregnancy (for the health of the fetus) appeared to be a factor in prompting relapse after the baby was born. During the immediate postpartum period women believed that physiological changes influence cigarette cravings. The stress of caring for a newborn, sleeplessness and adjusting to a new mothering identity were also reported to be important. Among women who quit smoking during pregnancy, those who relapse postpartum talk commonly about no longer needing to protect the baby and the effects of stress. Partner support and a sense of changed identity are cited as factors preventing relapse. © 2015 Society for the Study of Addiction.

    Two experiments with rats examined relapse of an operant behavior that occurred after the behavior was suppressed by reinforcing (incentivizing) an alternative behavior. In the first phase, a target response (R1) was reinforced. In a treatment phase, R1 was still reinforced, but a new response (R2) was introduced and associated with a larger reinforcer. As in human contingency management treatments, incentivizing R2 this way was effective at suppressing R1. However, when R2's reinforcement was discontinued, there was a robust and immediate relapse to R1. Experiment 1 found that the strength of R1 during relapse testing was not different from that seen in a no treatment control. Experiment 2 found that relapse could nevertheless be reduced by presenting reinforcers not contingent on responding during the test. Either the reinforcer for R1 or the reinforcer for R2 (which were qualitatively different types of food pellets) were effective. The experiments introduce a laboratory method for studying relapse and how to prevent it after contingency management treatments, and suggest at least one treatment that discourages relapse. The incentivized choice paradigm differs from other models of relapse of operant behavior (e.g., resurgence, renewal, reinstatement) in that it does not focus on the return of behaviors that are inhibited by extinction.

    Smoking during pregnancy and exposure to environmental tobacco smoke have harmful and sometimes devastating effects on the health of the newborn. Although interventions for smoking cessation during pregnancy demonstrate effectiveness for increasing smoking abstinence, the majority of women relapse in the postpartum period. However, modifying contributing factors for relapse may improve the success of sustained abstinence. Many parents are eager to quit smoking and willing to participate in smoking cessation interventions. Through a population-based approach to healthcare, neonatal nurses are in an ideal position to prevent relapse and to promote smoking abstinence; they can coordinate and lead efforts for establishing smoking cessation strategies that integrate obstetric, newborn, and pediatric services.

    Full Text Available A 59-year-old female patient presented at the outpatients’ Department of Ophthalmology with epiphora, eyelid swelling, and a foreign body feeling in the right eye. The symptoms were present for 4 months, and the patient was treated as suffering from relapsing conjunctivitis. The slit lamp examination revealed keratitis due to exposure, related with the deficient closure of the eyelids. There was a 2 mm difference in the readings with the Hertel exophthalmometry examination between the eyes. Her medical history was clear, and she was referred for computed tomography of the orbits and brain and biochemical examinations (FT3, FT4, and TSH to investigate the presence of an intraorbital mass. FT3 was significantly increased and TSH was accordingly low, indicating the diagnosis of Graves’ disease, which presented without other signs and symptoms apart from ophthalmopathy. Computed tomography scan excluded the diagnosis of an intraorbital mass. Therefore, it is important not to underestimate the ocular manifestations of systemic diseases.

    Full Text Available Ada Lo Schiavo,1 Rosa Valentina Puca,1 Francesca Romano,1 Roberto Cozzi2 1Department of Dermatology, Second University of Naples, Naples, Italy; 2Department of Dermatology, AORN "A Cardarelli", Naples, Italy Abstract: Statins, also known as 3-hydroxy-3-methylglutaril-CoA reductase inhibitors, are well-tolerated drugs used for prevention of atherosclerosis and cardiovascular events. Although they are generally considered safe, some serious adverse effects, such as myositis, myopathy, and rhabdomyolysis can rarely occur. Furthermore, recent data from long-term follow-up on patients who have been taking statins for a long period of time suggest that prolonged exposure to statins may trigger autoimmune reactions. The exact mechanism of statin-induced autoimmune reactions is unclear. Statins, as proapoptotic agents, release nuclear antigen into the circulation and may induce the production of pathogenic autoantibodies. Herein we report the case of a 70 year-old man who developed a relapse of pemphigus erythematosus, a syndrome with features of both lupus erythematosus and pemphigus, after atorvastatin intake.

    Full Text Available The purpose of the study was to identify changes in cognitive abilities that affect patients with relapsing remitting form of multiple sclerosis (MS and to find out which instrument manifests them best. The performance of MS patients was compared to a matched group of healthy people using three neuropsychological tests: Wisconsin card sorting test (WCST, Stroop color and word test and Trail making test (TMT part B. Results on all three tests indicate general cognitive impairments in the group of patients. Compared to the group of healthy people patients with MS exhibited impaired ability of abstract reasoning (WCST, impaired cognitive flexibility and less resistance to irrelevant stimuli (Stroop color and word test, slowed information processing and impaired ability of shifting attention from one symbol to another (TMT. The largest differences between groups occured in Stroop color and word test as well as in TMT. The estimation of cognitive abilities of MS patients is of high importance and sistematicaly observing of changes in those abilities should be considered.

    This study examined the feasibility and acceptability of a body motion-activated videogame, targeting the prevention of opioid relapse among youth in the context of outpatient treatment. Participants attended four weekly gameplay sessions. Surveys were conducted at baseline and following each week's gameplay and assessed satisfaction with gameplay, craving intensity, and self-efficacy to refuse opioids. Participants expressed a high level of satisfaction with the videogame throughout the 4 weeks and agreed with the statement that they would be more likely to attend treatment sessions if the game was present (mean=4.6; standard deviation [SD]=0.7) and would recommend the videogame to other people in treatment (mean=4.2; SD=0.8). All participants recommended playing the videogame as part of treatment at least weekly, with a third recommending playing daily. Self-reported cravings declined over the 4-week period from baseline (mean=12.7; SD=8.4) to Week 4 (mean=9.8; SD=8.3), although the decline was not significant. Although participants stated that they liked the game, one-third of participants had dropped out of the study by the fourth session of gameplay. Preliminary evidence indicates that a motion videogame for addiction recovery may be feasible and acceptable within the context of outpatient treatment, although additional efforts are needed to keep youth in treatment. Future studies are needed to assess the impact of the game on long-term abstinence, treatment adherence, and engagement.

    The majority of patients with hairy cell leukemia (HCL) achieve a response to therapy with cladribine or pentostatin with or without rituximab. However, late relapses can occur. Treatment of relapsed HCL can be difficult due to a poor tolerance to chemotherapy, increased risk of infections and decreased responsiveness to chemotherapy. The identification of BRAFV600E mutations and the role of aberrant MEK kinase and Bruton's tyrosine kinase (BTK) pathways in the pathogenesis of HCL have helped to develop novel targeted therapies for these patients. Currently, the most promising therapeutic strategies for relapsed or refractory HCL include recombinant immunoconjugates targeting CD22 (e.g. moxetumomab pasudotox), BRAF inhibitors such as vemurafenib and B cell receptor signaling kinase inhibitors such as ibrutinib. Furthermore, the VH4-34 molecular variant of classic HCL has been identified to be less responsive to chemotherapy. Herein, we review the results of the ongoing clinical trials and potential future therapies for relapsed/refractory HCL.

    Full Text Available A descriptive qualitative research conducted with 20 drug addicts during treatment at a Center of Psychosocial Attention for Alcohol and other Drugs, aimed to identify intra and interpersonal determinants of relapse perceived by the drug addict. The data were collected through semi-structured interviews, submitted to Content Analysis, and organized into categories following predictive determinants for relapse. The relapse occurred by intrapersonal determinants, as self-efficacy expressed by self-confidence in interrupting the drug consumption; the result expectation by anticipation of pleasurable drug effects; the motivation by the absence of volition to interrupt the consumption; coping with the difficulty to confront daily problems; negative and positive emotional states; and craving. Interpersonal determinants expressed by social support were related to the influence of thirds. The identification of these determinants during treatment to favor relapse prevention and effective rehabilitation.

    Despite recent progress in the management of chronic bacterial prostatitis (CBP), many cases relapse. Increased drug resistance patterns of responsible bacteria have been proposed as the most probable causative factor. Driven by the limited number of previous studies addressing this topic, we aimed to study whether antibiotic resistance increases in patients with CBP when relapse occurs. A secondary aim of this study was to determine the resistance patterns of responsible bacteria from patients with CBP. The study material consisted of bacterial isolates from urine and/or prostatic secretions obtained from patients with CBP. Bacterial identification was performed by using the Vitek 2 Compact system and susceptibility testing was performed by disc diffusion and/or the Vitek 2 system. Interpretation of susceptibility results was based on Clinical and Laboratory Standards Institute guidelines. A total of 253 samples from patients diagnosed with CBP for the first time (group A) and 137 samples from relapsing patients with a history of CBP and previous antibiotic treatment (group B) were analyzed. A significant reduction in bacterial resistance to the less used antibiotics (TMP-SMX, tetracyclines, aminoglycosides, penicillins, and macrolides) was noted. An increase in resistance to quinolones of many bacteria that cause CBP was also noted with the increase in resistance of enterococcus strains being alarming. Comparison of the resistance profile of CBP-responsible bacteria between samples from first-time-diagnosed patients and samples from relapsing patients revealed notable differences that could be attributed to previous antibiotic treatment.

    Recurrent tuberculosis is an important indicator of the effectiveness of tuberculosis control and can occur by relapse or exogenous reinfection. We conducted a retrospective cohort study on all bacteriologically confirmed tuberculosis cases that were successfully treated between 2000 and 2012 in Shanghai, an urban area with a high number but a low prevalence rate of tuberculosis cases and a low prevalence of HIV infection. Genotyping the Mycobacterium tuberculosis from clinical isolates was used to distinguish between relapse and reinfection. In total, 5.3% (710/13,417) of successfully treated cases had a recurrence, a rate of 7.55 (95% CI 7.01–8.13) episodes per 1000 person-years, more than 18 times the rate of tuberculosis in the general population. Patients who were male, age 30–59, retreatment cases, had cavitation, diabetes, drug-resistant or multidrug-resistant tuberculosis in their initial episode of tuberculosis, were at high risk for a recurrence. Among 141 recurrent cases that had paired isolates, 59 (41.8%) had different genotypes, indicating reinfection with a different strain. Patients who completed treatment were still at high risk of another episode of tuberculosis and exogenous reinfection contributed a significant proportion of the recurrent tuberculosis cases. Targeted control strategies are needed to prevent new tuberculosis infections in this setting. PMID:28237039

    Purpose The major causes of mortality after allogeneic hematopoietic-cell transplantation (allo-HCT) are relapse, graft-versus-host disease (GVHD), and infection. We have reported previously that alterations in the intestinal flora are associated with GVHD, bacteremia, and reduced overall survival after allo-HCT. Because intestinal bacteria are potent modulators of systemic immune responses, including antitumor effects, we hypothesized that components of the intestinal flora could be associated with relapse after allo-HCT. Methods The intestinal microbiota of 541 patients admitted for allo-HCT was profiled by means of 16S ribosomal sequencing of prospectively collected stool samples. We examined the relationship between abundance of microbiota species or groups of related species and relapse/progression of disease during 2 years of follow-up time after allo-HCT by using cause-specific proportional hazards in a retrospective discovery-validation cohort study. Results Higher abundance of a bacterial group composed mostly of Eubacterium limosum in the validation set was associated with a decreased risk of relapse/progression of disease (hazard ratio [HR], 0.82 per 10-fold increase in abundance; 95% CI, 0.71 to 0.95; P = .009). When the patients were categorized according to presence or absence of this bacterial group, presence also was associated with less relapse/progression of disease (HR, 0.52; 95% CI, 0.31 to 0.87; P = .01). The 2-year cumulative incidences of relapse/progression among patients with and without this group of bacteria were 19.8% and 33.8%, respectively. These associations remained significant in multivariable models and were strongest among recipients of T-cell-replete allografts. Conclusion We found associations between the abundance of a group of bacteria in the intestinal flora and relapse/progression of disease after allo-HCT. These might serve as potential biomarkers or therapeutic targets to prevent relapse and improve survival after allo-HCT.

    Conclusion: For routine neurosurgical practice, these entities are extremely rare; and hence a working knowledge is very essential for appropriate & timely management notwithstanding the neurosurgical desire to rule out the compressive lesions first. Neurological status deterioration may be halted with timely institution of appropriate chemotherapy. In the extensive literature review in pubmed, this may be only the 1st case of MPAL with extramedullary neurological manifestation, at the first clinical presentation.

    Relapses are a common feature of relapsing-remitting multiple sclerosis (RRMS) and increasing severity has been shown to be associated with higher healthcare costs, and to result in transient increases in disability. Increasing disability likely impacts work and leisure productivity, and lowers quality of life. The objective of this study was to characterize from the patient's perspective the impact of a multiple sclerosis (MS) relapse in terms of the economic cost, work and leisure productivity, functional ability, and health-related quality of life (HR-QOL), for a sample of patients with RRMS in the US treated with immunomodulatory agents. A cross-sectional, web-based, self-report survey was conducted among members of MSWatch.com, a patient support website now known as Copaxone.com. Qualified respondents in the US had been diagnosed with RRMS and were using an immunomodulatory agent. The survey captured costs of RRMS with questions about healthcare resource utilization, use of community services, and purchased alterations and assistive items related to MS. The Work and Leisure Impairment instrument and the EQ-5D were used to measure productivity losses and HR-QOL (health utility), respectively. The Goodin MS neurological impairment questionnaire was used to measure functional disability; questions were added about relapses in the past year. Of 711 qualified respondents, 67% reported having at least one relapse during the last year, with a mean of 2.2 ± 2.3 relapses/year. Respondents who experienced at least one relapse had significantly higher mean annual direct and indirect costs compared with those who did not experience a relapse ($US38 458 vs $US28 669; p = 0.0004) [year 2009 values]. Direct health-related costs accounted for the majority of the increased cost ($US5201; 53%) and were mainly due to increases in hospitalizations, medications, and ambulatory care. Indirect costs, including informal care and productivity loss, accounted for the

    Relapse to old, unhealthy eating habits is a major problem in human dietary treatments. The mechanisms underlying this relapse are unknown. Surprisingly, until recently this clinical problem has not been systematically studied in animal models. Here, we review results from recent studies in which a reinstatement model (commonly used to study relapse to abused drugs) was employed to characterize the effect of pharmacological agents on relapse to food seeking induced by either food priming (non-contingent exposure to small amounts of food), cues previously associated with food, or injections of the pharmacological stressor yohimbine. We also address methodological issues related to the use of the reinstatement model to study relapse to food seeking, similarities and differences in mechanisms underlying reinstatement of food seeking versus drug seeking, and the degree to which the reinstatement procedure provides a suitable model for studying relapse in humans. We conclude by discussing implications for medication development and future research. We offer three tentative conclusions: (1)The neuronal mechanisms of food-priming- and cue-induced reinstatement are likely different from those of reinstatement induced by the pharmacological stressor yohimbine. (2)The neuronal mechanisms of reinstatement of food seeking are possibly different from those of ongoing food-reinforced operant responding. (3)The neuronal mechanisms underlying reinstatement of food seeking overlap to some degree with those of reinstatement of drug seeking.

    Allogeneic SCT for myeloma may be curative for young patients, but its role remains controversial because of a reported high TRM in some series. Since 1991, we have performed 25 allografts for myeloma using fully matched sibling donors. Of the 18 evaluable patients, 13 achieved CR at a median time of 2.5 months post-transplant. The five patients who were not in CR when assessed at 3 months received a short course of alpha-interferon and four subsequently achieved CR with this approach at a median of 82 days. One patient who failed to respond to IFN went on to achieve CR after four doses of DLI therapy, thus giving an overall CR rate of 72%. Seven patients have relapsed at a median of 4.7 years post-transplant (range 1.38-7.7 years) including two patients who had received IFN therapy. In five of these cases, relapse has been as a localised area of bone disease or isolated plasmacytoma with no evidence of marrow involvement by trephine biopsy or molecular analysis. All patients with localised relapse were treated with local radiotherapy +/-DLI and four are currently disease free despite two patients having had further treatment for a second localised lesion. Six patients died of TRM (24%) and the OS at 8 years is currently 69% with an EFS of 26%. These results suggest that allogeneic SCT for myeloma can be carried out with an acceptable TRM and a high CR rate. However, late relapses as localised disease may be a frequent finding and may represent foci of myeloma not eradicated by the conditioning. The use of pretransplant MRI scanning and top-up radiotherapy to involved areas may be useful in preventing this type of relapse.

    A 39-year-old man with Philadelphia chromosome-positive acute lymphoblastic leukemia (LAL Ph+) developed progressive vision loss to no light perception in his right eye. He had optic disk edema and later developed central artery and vein occlusions. Pan-photocoagulation, as well as radiotherapy of the whole brain were performed in several fractions. Unfortunately the patient died of hematological relapse 4 months later. Optic nerve infiltration may appear as an isolated sign of a leukemia relapse, even before a hematological relapse occurs. Leukemic optic neuropathy is a critical sign, not only for vision, but also for life, and radiotherapy should be immediately performed before irreversible optic nerve damage occurs.

  7. Relapse Prevention: An Overview of Marlatts Cognitive- Behavioral Model

    Directory of Open Access Journals (Sweden)

    2008-11-01

    Full Text Available Relapse prevention(RPis an important component of alcoholism treatment. The RP model proposed by Marlatt and Gordon suggests that both immediate determinants (e.g.,high- risk situations, coping skills, outcome expectancies, and the abstinence violation effect and covert antecedents (e.g., lifestyle factor and urges and cravings can contribute to relapse.The RP model also incorporates numerous specific and global intervention strategies that allow therapist and client to address each step of the relapse process. Specific interventions include identifying specific high-risk situations for each client and enhancing the client's skills for coping with those situations, increasing the client's self- efficacy, eliminating myths regarding alcohol's effects, managing lapses, and restructuring the client's perceptions of the relapse process. Global strategies comprise balancing the client's lifestyle and helping him or her develop positive addictions, employing stimulus control techniques and urgemanagement techniques, and developing relapse road maps. Several studies have provided theoretical and practical support for the RP model.

    Full Text Available Since leprosy is both treated and controlled by multidrug therapy (MDT it is important to monitor recurrent cases for drug resistance and to distinguish between relapse and reinfection as a means of assessing therapeutic efficacy. All three objectives can be reached with single nucleotide resolution using next generation sequencing and bioinformatics analysis of Mycobacterium leprae DNA present in human skin.DNA was isolated by means of optimized extraction and enrichment methods from samples from three recurrent cases in leprosy patients participating in an open-label, randomized, controlled clinical trial of uniform MDT in Brazil (U-MDT/CT-BR. Genome-wide sequencing of M. leprae was performed and the resultant sequence assemblies analyzed in silico.In all three cases, no mutations responsible for resistance to rifampicin, dapsone and ofloxacin were found, thus eliminating drug resistance as a possible cause of disease recurrence. However, sequence differences were detected between the strains from the first and second disease episodes in all three patients. In one case, clear evidence was obtained for reinfection with an unrelated strain whereas in the other two cases, relapse appeared more probable.This is the first report of using M. leprae whole genome sequencing to reveal that treated and cured leprosy patients who remain in endemic areas can be reinfected by another strain. Next generation sequencing can be applied reliably to M. leprae DNA extracted from biopsies to discriminate between cases of relapse and reinfection, thereby providing a powerful tool for evaluating different outcomes of therapeutic regimens and for following disease transmission.

    Full Text Available Background Extramedullary alignment is a well established surgical technique during total knee replacement. There are different methods to achieve accuracy but variability is quite extensive. To attain uniformity in the surgical technique we have been using the tibialis tendon to align our resection guide. This may prove to be a useful aid for surgeons during knee replacement surgery. Objectives The purpose of our study was to establish if tibialis anterior tendon represents the centre of ankle joint and if it could be used as an anatomical reference for alignment during knee replacement. Methods We designed a retrospective radiological cohort study. We studied sixty MRI scans of normal ankles. The centre of ankle joint was marked as a bisection point of the intermalleolar line at the level of superior surface of the talus. A line was drawn connecting the centre of Achilles tendon to the ankle centre and this was extended anteriorly. This line was found to have a constant relation to the ankle centre and it would simulate the positioning of the standard alignment device used. Results The tibialis anterior tendon lies less than 3mm medial to the ankle centre in the frontal plane. Conclusions We conclude that the tibialis anterior tendon can be used during knee replacement surgery as an accurate alignment guide.

    The purpose of this study was to determine the added value of the perimedullary spinal vein enlargement sign on magnetic resonance imaging (MRI) in distinguishing intradural-extramedullary tumors (IDEMTs) from intramedullary spinal tumors (IMTs). Two hundred and eight consecutive spinal intradural tumors with histopathologic confirmation (21 IMTs, 187 IDEMTs) were enrolled. Two readers blinded to the final pathological diagnosis and clinical data independently assessed the venous enlargement sign to determine the agreement between them and jointly distinguished IDEMTs from IMTs according to the common MRI findings. Sensitivity, specificity, and accuracy for the diagnosis of IDEMTs were calculated for the common MRI findings, vein enlargement sign, and a combination of both. Intraobserver agreement and interobserver agreement for both readers was excellent. The sensitivity, specificity, and accuracy of common MRI findings for differentiating IDEMTs from IMTs were 83.4, 95.2, and 89.3 %, respectively. Thirty-one IDEMTs were mistakenly diagnosed as IMTs, in which seven were cases with vein enlargement signs. By applying the vein enlargement sign to the common MRI findings, the specificity remained at 95.2 %, while the sensitivity improved to 89.3 % and the accuracy increased to 92.3 %. The spinal perimedullary vein enlargement sign is useful in assessing intradural tumors and to differentiate IDEMTs from IMTs. (orig.)

    About 10% of patients with essential thrombocythemia (ET) or myelofibrosis (MF) that lack mutations in JAK2 harbor an activating mutation in the thrombopoietin receptor, MPLW515L. Distinct from the JAK2V617F retroviral transplant model, the MPLW515L model recapitulates many features of ET and MF, including severe fibrosis and thrombocytosis. We have tested EXEL-8232, an experimental potent JAK2 inhibitor, for efficacy in suppression of thrombocytosis in vivo and for its ability to attenuate MPLW515L myeloproliferative disease. EXEL-8232 was administered for 28 days q12 h by oral gavage at doses of 30 or 100 mg/kg, prospectively. Animals treated with EXEL-8232 at 100 mg/kg had normalized high platelet counts, eliminated extramedullary hematopoiesis in the spleen and eliminated bone marrow fibrosis, whereas the wild-type controls did not develop thrombocytopenia. Consistent with a clinical response in this model, we validated surrogate end points for response to treatment, including a reduction of endogenous colony growth and signaling inhibition in immature erythroid and myeloid primary cells both in vitro and upon treatment in vivo. We conclude that EXEL-8232 has efficacy in treatment of thrombocytosis in vivo in a murine model of ET and MF, and may be of therapeutic benefit for patients with MPL-mutant MPN.

    Full Text Available Elisabeth QuoixService de Pneumologie, Hôpitaux Universitaires, Strasbourg, FranceAbstract: Small cell lung cancer (SCLC represents about 15% to 20% of all lung cancers. Chemotherapy is the cornerstone of the treatment, cisplatin–etoposide combination being the most used combination as first-line therapy. Despite high initial chemosensitivity, most SCLC patients will experience relapse sooner or later. Unfortunately, second-line chemotherapy does not result in a high response rate like first-line therapy, most patients having developed wide chemoresistance. This chemoresistance is far more important in refractory patients, ie, those who never responded to first-line therapy or who relapsed within 3 months after the end of chemotherapy, than in sensitive patients, ie, those who relapse more than 3 months after the end of chemotherapy. Topotecan, a topoisomerase I inhibitor, is the most studied drug in this second-line setting and has proved its efficacy as a single agent and in combination. A phase III trial comparing oral topotecan to best supportive care (BSC in relapsed SCLC demonstrated a significant survival benefit as well as a better quality of life. Although the usual schedule is 1.5 mg/m2, days 1–5 intravenously, it is not convenient for patients with relapsed SCLC, especially those who are refractory because of their short survival expectation. Oral topotecan is of similar efficacy and much more convenient with limited stay in a treatment unit and has a comparable toxicity profile for these patients with short expected survival. Combination of topotecan with platinum salts or taxanes does not seem to improve further the outcome of the patients and thus single-agent therapy with topotecan is the standard treatment for relapsed SCLC.Keywords: topotecan, small cell lung cancer, chemoresistance

    Acanthameoba keratitis is a serious ophthalmological condition with a potentially vision-threatening prognosis. Early diagnosis and recognition of relapse, and the detection of persistent Acanthamoeba cysts, are essential for informing the prognosis and managing the condition. We suggest the use of in vivo confocal microscopy not only to identify the early signs of relapse after keratoplasty in patients with Acanthamoeba keratitis, but also as an additional follow-up tool after antimicrobial crosslinking. This study shows that in vivo confocal microscopy is, in experienced hands, a quick and reliable diagnostic tool. Clin.

    2011-01-01

    Full Text Available Lidocaine unmasks silent symptoms and eases neuropathic pain in multiple sclerosis patients; however, the effects of lidocaine in neuromyelitis optica have never been reported. We describe the case of a 59-year-old Japanese woman with neuromyelitis optica spectrum disorder who developed optic neuritis 1 day after intravenous lidocaine injection for treating allodynia. Her symptom seemed to result from a relapse of neuromyelitis optica induced by lidocaine administration, and not because of the transient effects of intravenous lidocaine administration. The possibility that lidocaine administration results in relapse of neuromyelitis optica due to its immunomodulating effects cannot be ruled out.

    Acute septicemic spirochetosis was diagnosed in an adult male northern spotted owl (Strix occidentalis caurina) found dead in Kittitas County, Washington, USA. Gross necropsy findings included marked enlargement of the liver and spleen and serofibrinous deposits on the serous membranes lining the body cavities and the pericardial and perihepatic sacs. Microscopic observations included macrophage infiltration in the liver and spleen with mild thrombosis and multifocal necrosis, as well as hemorrhage and acute inflammation in the choroid plexus of the brain. No viruses or pathogenic bacteria were isolated from brain, liver, or spleen, and no parasites were found in blood smears or impression smears of the liver. Chlamydial culture attempts were unsuccessful and no chlamydial antibodies were detected in serum. In silver-stained microscopic sections and by transmission electron microscopy of liver, numerous long, thin, spiral-shaped bacteria were seen in the liver, spleen, cerebral ventricles, and within blood vessels in many organs. The organism was identified as a member of the Borrelia genus by sequence analysis of the PCR-amplified 16S rRNA gene. The most closely related species is B. hermsii, an agent of relapsing fever in humans in the western United States. This is the first report of a relapsing fever-related Borrelia in a wild bird.

    Relapse is a common factor within the behavior change process. However, there is scarce and limited knowledge of smoking relapse situations in population-based samples. The aim of this study was to identify smoking relapse situations among a sample of Spanish relapsers from the general population. A sample of 775 relapsers was recruited among the general population using a snowball method. Participants completed a survey including sociodemographic, smoking-related and psychopathology variables. Smoking relapse situations were identified through specific questions assessing different aspects related to the last relapse episode. The majority of smoking relapse situations were attributed to positive affect (36.6%) and negative affect (34.3%), followed by lack of control (10.1%), smoking habit (6.7%), craving or nicotine withdrawal (6.3%), and social pressure (5.9%). Being unemployed and having a mental disorder in the past increased the likelihood of relapse in situations of negative affect. Being single and having quit smoking to save money were associated with an increased likelihood of relapse in situations of positive affect. Affect plays a significant role in smoking relapse among a community sample of unassisted Spanish smokers. Relapse may be much more of an affective and situational process than a habit, physiological or social pressure. Findings from this study may help develop tailored community smoking relapse prevention strategies or programs. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Relapse is a common measure of disease activity in relapsing-remitting multiple sclerosis (MS). The objective of this study was to test the content validity of an operational algorithm for detecting relapse in claims data. A claims-based relapse detection algorithm was tested by comparing its detection rate over a 1-year period with relapses identified based on medical chart review. According to the algorithm, MS patients in a US healthcare claims database who had either (1) a primary claim for MS during hospitalization or (2) a corticosteroid claim following a MS-related outpatient visit were designated as having a relapse. Patient charts were examined for explicit indication of relapse or care suggestive of relapse. Positive and negative predictive values were calculated. Medical charts were reviewed for 300 MS patients, half of whom had a relapse according to the algorithm. The claims-based criteria correctly classified 67.3% of patients with relapses (positive predictive value) and 70.0% of patients without relapses (negative predictive value; kappa 0.373: p value of the operational algorithm. Limitations of the algorithm include lack of differentiation between relapsing-remitting MS and other types, and that it does not incorporate measures of function and disability. The claims-based algorithm appeared to successfully detect moderate-to-severe MS relapse. This validated definition can be applied to future claims-based MS studies.

  7. Functional symptoms in clinically definite MS--pseudo-relapse syndrome.

    2012-02-03

    Although the diagnostic criteria for multiple sclerosis (MS) have become more formalized and sensitive in the era of magnetic resonance imaging (MRI) scanning, the assessment of individual relapses may not always be straightforward or easily linked to a particular lesion seen on imaging. In addition, acute episodes often have to be assessed outside of normal working hours or when the individual patients usual medical team is not available. Often the emergency department physicians have little formal neurological training and are under time pressure to get patients through the system as quickly as possible. It is therefore possible to mislabel functional symptoms as being true relapses. To illustrate scenarios of possible pseudo-relapse, three clinical vignettes are described. Misclassification of functional symptoms as relapse carries a number of inherent risks. Functional symptoms can be multifactorial and may cause a burden of disease. A multidisciplinary approach may be useful in minimizing unnecessary harm and identify if there is more than meets the eye to an episode of clinical deterioration.

    Most women who quit smoking during pregnancy will relapse postpartum. Previous efforts to prevent postpartum relapse have been unsuccessful at increasing rates of sustained abstinence. To evaluate the relative efficacy of 2 different approaches to prevent postpartum smoking relapse. Pregnant women who recently had quit smoking were recruited before the end of pregnancy. Intervention sessions were conducted through a combination of telephone calls and in-person visits beginning at delivery and continuing through 24 weeks postpartum. Participants completed assessments at the prenatal baseline and at 12, 24, and 52 weeks postpartum. Participants were recruited between March 2008 and December 2012. The dates of the analysis were April 2014 to February 2015. Women received postpartum-adapted, behavioral smoking relapse prevention intervention and were randomly assigned to an enhanced cognitive behavioral intervention that included additional specialized strategies and content focused on women's postpartum concerns about mood, stress, and weight (Strategies to Avoid Returning to Smoking [STARTS]) or a supportive, time and attention-controlled comparison (SUPPORT). Intervention began before delivery and continued through 24 weeks postpartum. The primary outcome was biochemically confirmed sustained tobacco abstinence at 52 weeks postpartum. Secondary outcomes were self-reported mood, levels of perceived stress, and degree of concern about smoking-related weight gain. The study cohort comprised 300 participants (150 randomly assigned to each group). Their mean (SD) age was 24.99 (5.65) years. Overall, 38.0% (114 of 300), 33.7% (101 of 300), and 24.0% (72 of 300) of the sample maintained abstinence at 12, 24, and 52 weeks' postpartum, respectively. There were no differences between the intervention groups in abstinence or time to relapse. Self-reported depressive symptoms and perceived stress significantly improved over time, and improvements were similar for both

    Methadone maintenance treatment (MMT) is recognized as one of the most effective treatments for heroin addiction but its effect is dimmed by the high incidence of heroin relapse. However, underlying neurobiology mechanism of heroin relapse under MMT is still largely unknown. Here, we took advantage of a resting-state fMRI technique by analysis of regional homogeneity (ReHo), and tried to explore the difference of brain function between heroin relapsers and non-relapsers in MMT. Forty MMT patients were included and received a 12-month follow-up. All patients were given baseline resting-state fMRI scans by using a 3.0 T GE Signa Excite HD whole-body MRI system. Monthly self-report and urine test were used to assess heroin relapse or non-relapse. Subjective craving was measured with visual analog scale. The correlation between ReHo and the degree of heroin relapse was analyzed. Compared with the non-relapsers, ReHo values were increased in the bilateral medial orbitofrontal cortex, right caudate, and right cerebellum of the heroin relapsers while those in the left parahippocampal gyrus, left middle temporal gyrus, right lingual gyrus, and precuneus were decreased in heroin relapsers. Importantly, altered ReHo in the right caudate were positively correlated with heroin relapse rates or subjective craving response. Using the resting-state fMRI technique by analysis of ReHo, we provided the first resting-state fMRI evidence that right caudate may serve as a potential biomarker for heroin relapse prediction and also as a promising target for reducing relapse risk.

    2017-07-01

    Full Text Available Purpose: Despite recent progress in the management of chronic bacterial prostatitis (CBP, many cases relapse. Increased drug resistance patterns of responsible bacteria have been proposed as the most probable causative factor. Driven by the limited number of previous studies addressing this topic, we aimed to study whether antibiotic resistance increases in patients with CBP when relapse occurs. A secondary aim of this study was to determine the resistance patterns of responsible bacteria from patients with CBP. Materials and Methods: The study material consisted of bacterial isolates from urine and/or prostatic secretions obtained from patients with CBP. Bacterial identification was performed by using the Vitek 2 Compact system and susceptibility testing was performed by disc diffusion and/or the Vitek 2 system. Interpretation of susceptibility results was based on Clinical and Laboratory Standards Institute guidelines. Results: A total of 253 samples from patients diagnosed with CBP for the first time (group A and 137 samples from relapsing patients with a history of CBP and previous antibiotic treatment (group B were analyzed. A significant reduction in bacterial resistance to the less used antibiotics (TMP-SMX, tetracyclines, aminoglycosides, penicillins, and macrolides was noted. An increase in resistance to quinolones of many bacteria that cause CBP was also noted with the increase in resistance of enterococcus strains being alarming. Conclusions: Comparison of the resistance profile of CBP-responsible bacteria between samples from first-time-diagnosed patients and samples from relapsing patients revealed notable differences that could be attributed to previous antibiotic treatment.

    Full Text Available It has been documented that there is a tendency for skeletal relapse after orthognathic surgery. This relapse occurs more often following mandibular bilateral sagittal split osteotomy setbacks. The possible causes for lack of postsurgical stability as well as the clinical recommendations to manage the relapse are presented. Among these recommendations is the creation of Iowa Spaces.

    The aim of this study was to evaluate of the patterns of post-surgical relapse after mandibular setback surgery with minimal orthodontic preparation (MS-MO). The subjects consisted of 15 patients with minimal pre-surgical orthodontic preparation (1.37 ± 1.69 months). Lateral cephalograms were taken in pre-surgical (T0), post-surgical 1 month (T1) and immediately after debonding (T2) stages. To evaluate the surgical changes (T1-T0) and the relapse (T2-T1), the linear and angular measurements were analyzed using paired t-test. Pearson's correlation coefficients of the horizontal and vertical relapses of Pog and Me to other measurements were calculated. Pog or Me in T1 were displaced rotationally on Ar-Pog or Ar-Me lines in T2 to evaluate the remaining surgical relapse except the rotational relapse from total relapse. The mandible relapsed anteriorly 3.53 mm (Pog) and 4.00 mm (Me) and superiorly 2.72 mm (Pog) and 2.44 mm (Me). FH to Ar-Pog and FH to Ar-Me decreased by about 2°. Pure surgical relapses at Pog and Me, except rotational relapses, were about 0.5 mm anteriorly and inferiorly 0.8 mm. The vertical relapse might induce mandibular rotation with the horizontal relapse. For an accurate prediction after MS-MO, the rotational relapse might be considered. Crown Copyright © 2012.

    Myeloid sarcoma is an extramedullary solid neoplasm composed of myeloid precursor cells. This tumor usually occurs simultaneously with or following the onset of acute leukemia. Rarely, it can be the first manifestation of acute myeloid leukemia. The tumor can occur anywhere in the body. However, primary involvement of the stomach without evidence of leukemia is exceedingly rare, and to the best of our knowledge, imaging features of isolated myeloid sarcoma of the stomach have not been reported in children. This case illustrates the imaging appearances of isolated myeloid sarcoma that initially manifested as gastric submucosal wall thickening and discusses the differential diagnosis, in a 15-year-old girl without evidence of hematologic malignancy

    2014-03-01

    Full Text Available Background: The increasing of osteoblast activities during bone formation will be accompanied with the increasing expression of alkaline phosphatase enzyme (ALP. ALP can be obtained from clear fluid excreted by gingival crevicular fluid (GCF. Bone turnover, especially bone formation process, can be monitored through the expression of ALP secreted by GCF during orthodontic treatment. Thus, retention period is an important period that can be monitored through the level of bone metabolism around teeth. Purpose: This research were aimed to determine the relation of distance change caused by tooth relapse and ALP activities in gingival crevicular fluid after orthodontic; and to determine ALP as a potential biomarker of bone formation during retention period. Methods: Lower incisors of 25 guinea pigs were moved 3 mm to the distally by using open coil spring. Those relapse distance were measured and the gingival crevicular fluid was taken by using paper points to evaluate ALP levels on days 0, 3, 7, 14 and 21 respectivelly by using a spectrophotometer (405 nm. t-test and ANOVA test were conducted to determine the difference of ALP activities among the time intervals. The correlation regression analysis was conducted to determine the relation of distance change caused by the relapse tooth movement and ALP activities. Results: The greatest relapse movement was occurred on day 3 after open coil spring was removed. There was significant difference of the average of distance decrease among groups A1-A5 (p<0.05. It was also known that ALP level was increased on day 3, but there was no significant difference of the average level of ALP among groups A1-A5 (p>0.05. Finally, based on the results of correlation analysis between the ALP level decreasing and the relapse distance on both right and left of mesial and distal sides, it is known that there was no relation between those two variables (p>0.05. Conclusion: It can be concluded that relapse after orthodontic

    To test for the possible presence of really isolated galaxies, which form a randomly distributed population in voids, we compare the distribution of most isolated galaxies in an observed sample with distributions of the same number of random points using the nearest neighbour test. The results show that the random population of really isolated galaxies does not exist - even the most isolated galaxies are connected with systems of galaxies, forming their outlying parts.

    2017-07-01

    A 49-year-old woman experienced a local relapse of a primary follicular lymphoma (FL) of the conjunctiva. She received 4 weekly intra-lesional injections followed by 6 monthly injections of rituximab (6mg/ml). A clinical response was achieved after first injection. No adverse ocular event or signs of lymphoma relapse were seen after 10 months of follow-up. Intralesional administration of rituximab for treating primary FL of the conjunctiva was an effective and safe therapeutic option; therefore it could be an alternative to other conventional treatments, such as radiotherapy or chemotherapy.

    In the past 20 years the treatment scenario of multiple sclerosis has radically changed. The increasing availability of effective disease-modifying therapies has shifted the aim of therapeutic interventions from a reduction in relapses and disability accrual, to the absence of any sign of clinical...... or MRI activity. The choice for therapy is increasingly complex and should be driven by an appropriate knowledge of the mechanisms of action of the different drugs and of their risk-benefit profile. Because the relapsing phase of the disease is characterised by inflammation, treatment should be started...... as early as possible and aim to re-establish the normal complex interactions in the immune system. Before starting a treatment, neurologists should carefully consider the state of the disease, its prognostic factors and comorbidities, the patient's response to previous treatments, and whether the patient...

  13. Pyrexia-associated Relapse in Chronic Inflammatory Demyelinating Polyradiculoneuropathy: A Case Report.

    2018-04-27

    Chronic inflammatory demyelinating polyradiculoneuropathy is a relapsing-remitting or chronic progressive demyelinating polyradiculoneuropathy. We report the case of a patient with chronic inflammatory demyelinating polyradiculoneuropathy who experienced relapses on four occasions after experiencing pyrexia and flu-like symptoms. Our patient showed characteristic features, such as relapse after pyrexia and flu-like symptoms, remission after pyretolysis without treatment, and the absence of remarkable improvement in a nerve conduction study in the remission phase. The serum level of tumor necrosis factor-α was elevated in the relapse phase and reduced in the remission phase; thus, the induction of cytokine release by viral infection might have caused the relapses.

  14. Patterns of Failure After Proton Therapy in Medulloblastoma; Linear Energy Transfer Distributions and Relative Biological Effectiveness Associations for Relapses

    Purpose: The pattern of failure in medulloblastoma patients treated with proton radiation therapy is unknown. For this increasingly used modality, it is important to ensure that outcomes are comparable to those in modern photon series. It has been suggested this pattern may differ from photons because of variations in linear energy transfer (LET) and relative biological effectiveness (RBE). In addition, the use of matching fields for delivery of craniospinal irradiation (CSI) may influence patterns of relapse. Here we report the patterns of failure after the use of protons, compare it to that in the available photon literature, and determine the LET and RBE values in areas of recurrence. Methods and Materials: Retrospective review of patients with medulloblastoma treated with proton radiation therapy at Massachusetts General Hospital (MGH) between 2002 and 2011. We documented the locations of first relapse. Discrete failures were contoured on the original planning computed tomography scan. Monte Carlo calculation methods were used to estimate the proton LET distribution. Models were used to estimate RBE values based on the LET distributions. Results: A total of 109 patients were followed for a median of 38.8 months (range, 1.4-119.2 months). Of the patients, 16 experienced relapse. Relapse involved the supratentorial compartment (n=8), spinal compartment (n=11), and posterior fossa (n=5). Eleven failures were isolated to a single compartment; 6 failures in the spine, 4 failures in the supratentorium, and 1 failure in the posterior fossa. The remaining patients had multiple sites of disease. One isolated spinal failure occurred at the spinal junction of 2 fields. None of the 70 patients treated with an involved-field-only boost failed in the posterior fossa outside of the tumor bed. We found no correlation between Monte Carlo-calculated LET distribution and regions of recurrence. Conclusions: The most common site of failure in patients treated with protons for

    We examined the hypothesis that stress-related blunting of cortisol in smokers is particularly pronounced in those with a history of severe life adversity. The two aims of this study were first to examine hormonal, craving, and withdrawal symptoms during ad libitum smoking and after the first 24 h of abstinence in smokers who experienced high or low levels of adversity. Second, we sought to examine the relationship between adversity and hypothalamic-pituitary-adrenal (HPA) hormones to predict relapse during the first month of a smoking cessation attempt. Hormonal and self-report measures were collected from 103 smokers (49 women) during ad libitum smoking and after the first 24 h of abstinence. HPA hormones were measured during baseline rest and in response to acute stress in both conditions. All smokers were interested in smoking cessation, and we prospectively used stress response measures to predict relapse during the first 4 weeks of the smoking cessation attempt. The results showed that high adversity was associated with higher distress and smoking withdrawal symptoms. High level of early life adversity was associated with elevated HPA activity, which was found in both salivary and plasma cortisol. Enhanced adrenocorticotropic hormone (ACTH) stress response was evident in high-adversity but not in low-adversity relapsers. This study demonstrated that early life adversity is associated with stress-related HPA responses. The study also demonstrated that, among smokers who experienced a high level of life adversity, heightened ACTH and cortisol responses were linked with increased risk for smoking relapse.

    Lenalidomide plus dexamethasone is a reference treatment for relapsed multiple myeloma. The combination of the proteasome inhibitor carfilzomib with lenalidomide and dexamethasone has shown efficacy in a phase 1 and 2 study in relapsed multiple myeloma. We randomly assigned 792 patients with relapsed multiple myeloma to carfilzomib with lenalidomide and dexamethasone (carfilzomib group) or lenalidomide and dexamethasone alone (control group). The primary end point was progression-free survival. Progression-free survival was significantly improved with carfilzomib (median, 26.3 months, vs. 17.6 months in the control group; hazard ratio for progression or death, 0.69; 95% confidence interval [CI], 0.57 to 0.83; P=0.0001). The median overall survival was not reached in either group at the interim analysis. The Kaplan-Meier 24-month overall survival rates were 73.3% and 65.0% in the carfilzomib and control groups, respectively (hazard ratio for death, 0.79; 95% CI, 0.63 to 0.99; P=0.04). The rates of overall response (partial response or better) were 87.1% and 66.7% in the carfilzomib and control groups, respectively (P<0.001; 31.8% and 9.3% of patients in the respective groups had a complete response or better; 14.1% and 4.3% had a stringent complete response). Adverse events of grade 3 or higher were reported in 83.7% and 80.7% of patients in the carfilzomib and control groups, respectively; 15.3% and 17.7% of patients discontinued treatment owing to adverse events. Patients in the carfilzomib group reported superior health-related quality of life. In patients with relapsed multiple myeloma, the addition of carfilzomib to lenalidomide and dexamethasone resulted in significantly improved progression-free survival at the interim analysis and had a favorable risk-benefit profile.

    Saccharomyces boulardii is a probiotic yeast that has been shown to have beneficial effects on the intestinal epithelial barrier and digestive immune system. There is preliminary evidence that S boulardii could be used to treat patients with Crohn's disease (CD). We performed a randomized, placebo-controlled trial to evaluate the effects of S boulardii in patients with CD who underwent remission during therapy with steroids or aminosalicylates. We performed a prospective study of 165 patients who achieved remission after treatment with steroids or salicylates; they were randomly assigned to groups given S boulardii (1 g/day) or placebo for 52 weeks. The primary end point was the percentage of patients in remission at week 52. Time to relapse, Crohn's disease activity index scores, and changes in parameters of inflammation were secondary end points. CD relapsed in 80 patients, 38 in the S boulardii group (47.5%) and 42 in the placebo group (53.2%, a nonsignificant difference). The median time to relapse did not differ significantly between patients given S boulardii (40.7 weeks) vs placebo (39.0 weeks). There were no significant differences between groups in mean Crohn's disease activity index scores or erythrocyte sedimentation rates or in median levels of C-reactive protein. In a post hoc analysis, nonsmokers given S boulardii were less likely to experience a relapse of CD than nonsmokers given placebo, but this finding requires confirmation. Although the probiotic yeast S boulardii is safe and well tolerated, it does not appear to have any beneficial effects for patients with CD in remission after steroid or salicylate therapies.

  18. Docetaxel-induced polyploidization may underlie chemoresistance and disease relapse.

    Although docetaxel significantly improves survival in a variety of malignancies, its clinical utility is severely restricted by acquired chemoresistance and disease relapse. To uncover the mechanisms underlying these all too common occurrences, an abundance of research has focused on mutations and gene expression patterns; however, these findings are yet to translate into improved outcomes for patients being administered this drug. These analyses have overlooked a promising lead in the quest to discern key mediators of resistance and relapse following docetaxel therapy: polyploidization. This process is manifested following docetaxel-mediated mitotic arrest by the appearance of giant, multinucleated cells, which slipped from mitosis without undergoing cytokinesis. Polyploid cells generally possess supernumerary centrosomes, are chromosomally instable, and resist chemotherapy. We thus suspect that chemoresistance and relapse following treatment with docetaxel might be combatted by co-administration of centrosome declustering drugs, which could selectively destroy polyploid cells given that normal cells do not possess amplified centrosomes, an intriguing paradigm that warrants further investigation.

    Chronic relapsing pancreatitis in children is an unusual condition that often goes undiagnosed and untreated for years. In light of recent reports in adults that endocrine and exocrine function may be preserved by early pancreaticojejunostomy, we reviewed our experience with this procedure (one Duval, 10 Puestows) in 10 children between 1969 and 1989. The underlying etiology was familial pancreatitis in four patients, one case of unknown etiology, congenital ductal anomalies in four (one pancreas divisum, one annular pancreas, one choledochal cyst, and one ductal stenosis), and posttraumatic in one. All 10 had intractable recurrent abdominal pain. Preoperatively, only three patients evidenced exocrine insufficiency and none had endocrine insufficiency. There was complete resolution of pain in eight patients and improvement in two during a mean observation period of 4 years (range, 7 months to 19.75 years). Exocrine insufficiency resolved in two patients but has persisted in the third patient now on Viokase. Endocrine insufficiency has developed during follow-up in one patient. Pancreaticojejunostomy provides excellent relief of recurrent pain in chronic relapsing pancreatitis in children. Endoscopic retrograde cholangiopancreatography (ERCP) is indicated when the diagnosis of chronic relapsing pancreatitis is suspected to define the ductal anatomy. Pancreaticojejunostomy may prevent the progression of exocrine and endocrine insufficiency if performed early in the course of the disease.

    Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disorder that is associated with paraneoplastic diseases. Because OMS can frequently relapse, patients may be inflicted with neurological problems for a long time. Recently, rituximab (RTX) was introduced as a drug to treat OMS. To assess RTX treatment, we studied a patient who experienced recurrence of OMS. A 2-year-old Japanese boy, who had left adrenal neuroblastoma, suddenly showed OMS symptoms, including ataxia and opsoclonus. Surgical resection of the tumor and subsequent steroid therapy ameliorated his symptoms. When OMS relapsed during the time when prednisolone was reduced, he was treated with full-dose RTX therapy (375 mg/m2/week) for 4 consecutive weeks. However, 1year later, he presented again with OMS symptoms. This time, we only administered an additional single dose of RTX treatment (375 mg/m2), allowing remission of OMS symptoms. During 2 years after the additional RTX treatment, OMS symptoms did not appear, even when prednisolone was reduced. He had no adverse events associated with RTX during the whole treatment period. An additional single-dose RTX therapy might be effective for relapsed OMS patients who were previously treated with full-dose RTX therapy. Copyright © 2015 The Japanese Society of Child Neurology.

    To study the effect of pregnancy on the frequency of neuromyelitis optica spectrum disorder (NMOSD) relapse and evaluate rates of pregnancy-related complications in an international multicenter setting. We administered a standardized survey to 217 women with NMOSD from 7 medical centers and reviewed their medical records. We compared the annualized relapse rate (ARR) during a baseline period 2 years prior to a participant's first pregnancy to that during pregnancy and to the 9 months postpartum. We also assessed pregnancy-related complications. There were 46 informative pregnancies following symptom onset in 31 women with NMOSD. Compared to baseline (0.17), ARR was increased both during pregnancy (0.44; p = 0.035) and during the postpartum period (0.69; p = 0.009). The highest ARR occurred during the first 3 months postpartum (ARR 1.33). A total of 8 of 76 (10.5%) with onset of NMOSD prior to age 40 experienced their initial symptom during the 3 months postpartum, 2.9 times higher than expected. The postpartum period is a particularly high-risk time for initial presentation of NMOSD. In contrast to published observations in multiple sclerosis, in neuromyelitis optica, relapse rate during pregnancy was also increased, although to a lesser extent than after delivery. © 2017 American Academy of Neurology.

    High-dose therapy and auto-SCT remain integral in the initial treatment of multiple myeloma (MM), and are increasingly being applied for management of relapsed disease. We examined the outcomes in 98 patients undergoing salvage auto-SCT (auto-SCT2) for relapsed MM after receiving an initial transplant (auto-SCT1) between 1994 and 2009. The median age at auto-SCT2 was 60 years (range: 35-74). The median time between auto-SCT1 and auto-SCT2 was 46 months (range: 10-130). Treatment-related mortality was seen in 4%. The median PFS from auto-SCT2 was 10.3 (95% confidence interval (CI): 7-14) months and the median OS from auto-SCT2 was 33 months (95% CI: 28-51). In a multivariable analysis, shorter time to progression (TTP) after auto-SCT1, not achieving a CR after auto-SCT2, higher number of treatment regimens before auto-SCT2 and a higher plasma cell labeling index at auto-SCT2 predicted for shorter PFS. However, only a shorter TTP after auto-SCT1 predicted for a shorter OS post auto-SCT2. Hence, auto-SCT2 is an effective and feasible therapeutic option for MM patients relapsing after other treatments, especially in patients who had a TTP of at least 12 months after their auto-SCT1.

    Rituximab is effective against complicated childhood steroid-dependent nephrotic syndrome (SDNS). Peripheral blood B-lymphocyte (B-cell) depletion is strongly correlated with persistent remission, relapse rarely occurring during B-cell depletion; however, we have encountered several such patients. We retrospectively analyzed the characteristics and clinical course of 82 patients with SDNS treated with rituximab from January 2007 to December 2012 in our institution. Six of 82 patients (7.3%) had relapses during B-cell depletion after receiving rituximab (relapsed group). The remaining 76 patients did not have relapses during B-cell depletion (non-relapsed group). The median time to initial relapse during B-cell depletion was 85 days after receiving rituximab, which is significantly shorter than in the non-relapsed group (410 days, p = 0.0003). The median annual numbers of relapses after receiving rituximab were 2.5 and 0.9 in the relapsed and non-relapsed groups, respectively (p depletion did not differ between the two groups. Relapse during B-cell depletion after receiving rituximab suggests that various pathophysiological mechanisms play a part in childhood nephrotic syndrome.

    Intramedullary and extramedullary strategies of pertrochanteric fracture fixation are still controversial, but new percutaneous devices may give advantages regarding operative time, blood loss and rate of cardiovascular complications. We retrospectively analyze our cases regarding Anteversa ® plate (Intrauma, Turin, Italy) fixation of pertrochanteric femoral fractures, focusing on the correlation between two radiographical parameters (tip-apex distance "TAD" and calcar referenced tip-apex distance "CalTAD") and the occurrence of cut-out. The purpose of this study was to determine if these predicting factors of cut-out are reliable in the treatment of proximal femoral fractures with the Anteversa plate. A series of 77 patients with 53 31-A1 fracture types and 24-A2 fractures completed a 12-month-follow-up. Clinical outcomes were evaluated according to Parker-Palmer Mobility Score at the final follow-up. TAD and CalTAD were considered to determine their correlation with cut-out events. The mean Parker-Palmer Score was 6.94 in A1 group and 7.41 in A2 group ( p  = 0.47). Mean value of TAD index was 29.58, 29.81 in the A1 group and 29.08 in the A2 group, and mean value of CalTAD index was 30.87, 31.03 in the A1 group and 30.50 in the A2 group. We observed 3 cases of implant cut-out. We shared our sample in two groups, one group with TAD and CalTAD indices lower than 25 mm and another group higher than 25 mm to evaluate how the Palmer Parker score changed and no statistical differences were found between the two groups. Taking into consideration that good clinical results were obtained for TAD and CalTAD values superior to 25 mm, the prognostic value of 25 mm of TAD and CalTAD indices might not be appropriate to this new percutaneous plate.

    Acute myeloid leukemia (AML) is the most frequent type of acute leukemia in adults. Despite recent advances in the characterization of pathogenesis of AML, the cure rates are under 40%, being leukemia relapse the most common cause of treatment failure. Leukaemia relapse occurs due to clonal evolution or clonal escape. In this study, we aimed to analyze the clinical and biological factors influencing outcomes in patients with AML relapse. We included a total of 75 AML patients who experienced leukaemia relapse after achieving complete remission. We performed complete immunophenotyping and conventional karyotyping in bone marrow aspirates obtained at diagnosis and at leukemia relapse. Overall survival (OS) of the series was 3.7%±2.3, leukaemia progression being the most common cause of death. Patients relapsing before 12 months and those with adverse cytogenetic-molecular risk had statistically significant worse outcomes. A percentage of 52.5 of patients showed phenotypic changes and 50% cytogenetic changes at relapse. We did not find significant clinical factors predicting clonal evolution. The presence of clonal evolution at relapse did not have a significant impact on outcome. Patients with relapsed AML have a dismal prognosis, especially those with early relapse and adverse cytogenetic-molecular risk. Clonal evolution with phenotypic and cytogenetic changes occurred in half of the patients without predictive clinical factors or impact on outcome. Copyright © 2016 Elsevier España, S.L.U.

    Although current therapies for acute promyelocytic leukemia (APL), such as all- trans retinoic acid and arsenic trioxide, usually result in remission, some patients relapse. Early recognition of relapse is critical for prompt intervention. In this study, we systematically reviewed morphologic, immunophenotypic, and cytogenetic findings in paired diagnostic and relapsed APL cases and describe and quantify the changes in blast morphology at relapse. By electronic database search, we identified eight paired diagnostic and relapsed APL cases for which peripheral blood or bone marrow smears were available for review. For two cases, diagnostic material was available for relapse after hematopoietic cell transplantation. Neoplastic hypergranular or microgranular promyelocytes with indented or bivalve nuclei predominated at diagnosis in all patients. Most patients had undifferentiated blasts at relapse and/or hypergranular blast equivalents with round to oval nuclei. Classic acute promyelocytic leukemia cells with bivalve nuclei and bundles of cytoplasmic Auer rods were easily identifiable in fewer than half of cases at diagnosis and rare to absent in all relapsed cases. Morphologic features of relapsed APL overlap with other types of acute myeloid leukemia, creating diagnostic challenges, especially if no history is available when relapsing patients seek treatment for care. © American Society for Clinical Pathology, 2017.

    Negative affective states and alcohol-related stimuli increase risk of relapse in alcohol dependence. In research and in clinical practice, craving is often used as another important indicator of relapse, but this lacks a firm empirical foundation. The goal of the present study is to explore and compare determinants for relapse and craving, using Marlatt's (1996) taxonomy of high risk situations as a template. We conducted semi-structured interviews with 20 alcohol-dependent patients about their most recent relapse and craving episodes. Interview transcripts were carefully reviewed for their thematic content, and codes capturing the thematic content were formulated. In total, we formulated 42 relapse-related codes and 33 craving-related codes. Descriptions of craving episodes revealed that these episodes vary in frequency and intensity. The presence of alcohol-related stimuli (n = 11) and experiencing a negative emotional state (n = 11) were often occurring determinants of craving episodes. Both negative emotional states (n = 17) and testing personal control (n = 11) were viewed as important determinants of relapses. Craving was seldom mentioned as a determinant for relapse. Additionally, participants reported multiple determinants preceding a relapse, whereas craving episodes were preceded by only one determinant. Patient reports do not support the claim that craving by itself is an important proximal determinant for relapse. In addition, multiple determinants were present before a relapse. Therefore, future research should focus on a complexity of different determinants.

    Purpose: External beam radiation therapy to initial sites of disease may influence relapse patterns in high-risk neuroblastoma. However, the effect of systemic irradiation by use of total body irradiation (TBI) on anatomic patterns of relapse has not previously been investigated. Methods and Materials: We retrospectively analyzed patients receiving definitive treatment of high-risk neuroblastoma with subsequent relapse in bony metastatic sites, with a date of relapse between January 1, 1997, and December 31, 2012. Anatomic sites of disease, defined by metaiodobenzylguanidine (MIBG) avidity, were compared at diagnosis and at first relapse. The Fisher exact test was performed to compare relapse in initially involved sites between patients treated with and without TBI. Results: Seventy-four patients with a median age at diagnosis of 3.5 years (range, 0.3-15.3 years) had relapse in 227 sites of MIBG-avid metastatic disease, with a median time to relapse of 1.8 years. Of the 227 sites of first relapse, 154 sites (68%) were involved at diagnosis. When we compared relapse patterns in patients treated with and without TBI, 12 of 23 patients (52%) treated with TBI had relapse in ≥1 previously MIBG-avid site of disease whereas 40 of 51 patients (78%) treated without TBI had relapse in ≥1 previously MIBG-avid site of disease (P=.03). Conclusions: Patients treated with systemic irradiation in the form of TBI were significantly less likely to have relapse in prior sites of disease. These findings support further investigation into the role of radiopharmaceutical therapies in curative multimodality therapy.

    The treatment of relapsed chronic lymphocytic leukemia (CLL) has resulted in few durable remissions. Bruton's tyrosine kinase (BTK), an essential component of B-cell-receptor signaling, mediates interactions with the tumor microenvironment and promotes the survival and proliferation of CLL cells. We conducted a phase 1b-2 multicenter study to assess the safety, efficacy, pharmacokinetics, and pharmacodynamics of ibrutinib (PCI-32765), a first-in-class, oral covalent inhibitor of BTK designed for treatment of B-cell cancers, in patients with relapsed or refractory CLL or small lymphocytic lymphoma. A total of 85 patients, the majority of whom were considered to have high-risk disease, received ibrutinib orally once daily; 51 received 420 mg, and 34 received 840 mg. Toxic effects were predominantly grade 1 or 2 and included transient diarrhea, fatigue, and upper respiratory tract infection; thus, patients could receive extended treatment with minimal hematologic toxic effects. The overall response rate was the same in the group that received 420 mg and the group that received 840 mg (71%), and an additional 20% and 15% of patients in the respective groups had a partial response with lymphocytosis. The response was independent of clinical and genomic risk factors present before treatment, including advanced-stage disease, the number of previous therapies, and the 17p13.1 deletion. At 26 months, the estimated progression-free survival rate was 75% and the rate of overall survival was 83%. Ibrutinib was associated with a high frequency of durable remissions in patients with relapsed or refractory CLL and small lymphocytic lymphoma, including patients with high-risk genetic lesions.

Natalizumab monotherapy reduced risk of disability progression by 42%–54% and annualized relapse rate by 68% during a period of 2 years. Natalizumab was also associated with significant reductions in number of T2-hyperintense, gadolinium-enhancing, and T1-hypointense lesions and in volume of T2-hyperintense lesions (all p < 0.001 on magnetic resonance imaging. Furthermore, natalizumab-treated patients in AFFIRM experienced significant improvements from baseline in the physical and mental components of the Short Form-36 (p ≤ 0.01 and a 35% reduction in risk of clinically significant vision loss (p = 0.008 vs placebo. Natalizumab was well tolerated in phase 3 studies. Common adverse events were generally mild and included headache, fatigue, urinary tract infections, and arthralgia. Serious adverse events were similar between treatment groups. The incidence of serious hypersensitivity reactions associated with natalizumab was <1%. Progressive multifocal leukoencephalopathy was a rare complication of treatment, observed in 2 patients with MS who received natalizumab plus interferon β-1a. The robust clinical benefits of natalizumab, including benefits on patient-reported quality of life, make it an important addition to disease-modifying therapies available to patients with relapsing MS.Keywords: multiple sclerosis, natalizumab, α4-integrin antagonist

    To establish whether children with relapsing acquired demyelinating syndromes (RDS) and myelin oligodendrocyte glycoprotein antibodies (MOG-Ab) show distinctive clinical and radiologic features and to generate a diagnostic algorithm for the main RDS for clinical use. A panel reviewed the clinical characteristics, MOG-Ab and aquaporin-4 (AQP4) Ab, intrathecal oligoclonal bands, and Epstein-Barr virus serology results of 110 children with RDS. A neuroradiologist blinded to the diagnosis scored the MRI scans. Clinical, radiologic, and serologic tests results were compared. The findings showed that 56.4% of children were diagnosed with multiple sclerosis (MS), 25.4% with neuromyelitis optica spectrum disorder (NMOSD), 12.7% with multiphasic disseminated encephalomyelitis (MDEM), and 5.5% with relapsing optic neuritis (RON). Blinded analysis defined baseline MRI as typical of MS in 93.5% of children with MS. Acute disseminated encephalomyelitis presentation was seen only in the non-MS group. Of NMOSD cases, 30.7% were AQP4-Ab positive. MOG-Ab were found in 83.3% of AQP4-Ab-negative NMOSD, 100% of MDEM, and 33.3% of RON. Children with MOG-Ab were younger, were less likely to present with area postrema syndrome, and had lower disability, longer time to relapse, and more cerebellar peduncle lesions than children with AQP4-Ab NMOSD. A diagnostic algorithm applicable to any episode of CNS demyelination leads to 4 main phenotypes: MS, AQP4-Ab NMOSD, MOG-Ab-associated disease, and antibody-negative RDS. Children with MS and AQP4-Ab NMOSD showed features typical of adult cases. Because MOG-Ab-positive children showed notable and distinctive clinical and MRI features, they were grouped into a unified phenotype (MOG-Ab-associated disease), included in a new diagnostic algorithm. © 2017 American Academy of Neurology.

    Post-relapse survival (PRS) was evaluated in patients with Ewing sarcoma (EWS) enrolled in chemotherapy protocols based on the use of high-dose chemotherapy with busulfan and melfalan (HDT) as a first-line consolidation treatment in high-risk patients. EWS patients enrolled in ISG/SSG III and IV trials who relapsed after complete remission were included in the analysis. At recurrence, chemotherapy based on high-dose ifosfamide was foreseen, and patients who responded but had not received HDT underwent consolidation therapy with HDT. Data from 107 EWS patients were included in the analysis. Median time to recurrence (RFI) was 18 months, and 45 (42%) patients had multiple sites of recurrence. Patients who had previously been treated with HDT had a significantly (P = 0.02) shorter RFI and were less likely to achieve a second complete remission (CR2). CR2 status was achieved by 42 (39%) patients. Fifty patients received high-dose IFO (20 went to consolidation HDT). The 5-year PRS was 19% (95% CI 11 to 27%). With CR2, the 5-year PRS was 48% (95% CI 31 to 64%). Without CR2, median time to death was six months (range 1-45 months). According to the multivariate analysis, patients younger than 15 years, recurrence to the lung only, and RFI longer than 24 months significantly influenced the probability of PRS. Age, pattern of recurrence, RFI, and response to second-line chemotherapy influence post-relapse survival in patients with recurrent Ewing sarcoma. No survival advantage was observed from chemotherapy consolidation with HDT. © 2015 Wiley Periodicals, Inc.

    Idiopathic orbital inflammation (IOI) is defined as a benign non-infective clinical syndrome characterized by features of non-specific inflammation of the orbit without identifiable local or systemic causes. This can be called orbital myositis if the inflammation is predominantly in the orbital muscles. It is a diagnosis of exclusion based on clinical, radiological, and if necessary, histological findings. The most commons symptoms are swelling, ptosis, proptosis and painful eye movements. To our knowledge, this patient is the first with IOI to demonstrate relapsing flitting bilateral involvement of several individual extra-ocular muscles. (orig.)

    Background. A 10-year-old boy with a history of acute lymphoblastic leukaemia (ALL), but without previous evidence of central nervous system involvement, presented with seizures 3 years after complete remission. Materials and methods. MRI showed bilateral enlargement of the optic nerves despite normal ophthalmological examination. Results. Only the third cerebrospinal fluid examination showed 2 % blasts without concomitant bone-marrow infiltration. Enlargement of the optic nerves was consistent with bilateral leukaemic peri-optic nerve infiltration. The appearances returned to normal after chemotherapy. Conclusion. The optic nerves are a potential site of relapse in patients with systemic and meningeal ALL, even in the absence of ophthalmological signs. (orig.)

    There are thousands of survivors of the 2014 Ebola outbreak in west Africa. Ebola virus can persist in survivors for months in immune-privileged sites; however, viral relapse causing life-threatening and potentially transmissible disease has not been described. We report a case of late relapse in a patient who had been treated for severe Ebola virus disease with high viral load (peak cycle threshold value 13.2). A 39-year-old female nurse from Scotland, who had assisted the humanitarian effort in Sierra Leone, had received intensive supportive treatment and experimental antiviral therapies, and had been discharged with undetectable Ebola virus RNA in peripheral blood. The patient was readmitted to hospital 9 months after discharge with symptoms of acute meningitis, and was found to have Ebola virus in cerebrospinal fluid (CSF). She was treated with supportive therapy and experimental antiviral drug GS-5734 (Gilead Sciences, San Francisco, Foster City, CA, USA). We monitored Ebola virus RNA in CSF and plasma, and sequenced the viral genome using an unbiased metagenomic approach. On admission, reverse transcriptase PCR identified Ebola virus RNA at a higher level in CSF (cycle threshold value 23.7) than plasma (31.3); infectious virus was only recovered from CSF. The patient developed progressive meningoencephalitis with cranial neuropathies and radiculopathy. Clinical recovery was associated with addition of high-dose corticosteroids during GS-5734 treatment. CSF Ebola virus RNA slowly declined and was undetectable following 14 days of treatment with GS-5734. Sequencing of plasma and CSF viral genome revealed only two non-coding changes compared with the original infecting virus. Our report shows that previously unanticipated, late, severe relapses of Ebola virus can occur, in this case in the CNS. This finding fundamentally redefines what is known about the natural history of Ebola virus infection. Vigilance should be maintained in the thousands of Ebola survivors

    Predicting relapse after alcoholism treatment can be useful in targeting patients for aftercare services. However, a valid and practical instrument for predicting relapse risk does not exist. Based on a prospective study of alcoholism treatment, we developed the Risk of Alcoholic Relapse Scale (RARS) using items taken from the Addiction Severity Index and some basic demographic information. The RARS was cross-validated using two non-overlapping samples, and tested for its ability to predict relapse across different models of treatment. The RARS predicted relapse to drinking within 6 months after alcoholism treatment in both the original and the validation sample, and in a second validation sample it predicted admission to new treatment 3 years after treatment. The RARS can identify patients at high risk of relapse who need extra aftercare and support after treatment.

    Alcohol relapse after liver transplant heightens concern about recurrent disease, nonadherence to the immunosuppression regimen, and death. To develop a scoring system to stratify risk of alcohol relapse after liver transplant. Retrospective medical record review. All adult liver transplants performed from May 2002 to February 2011 at a single center in the United States. The incidence of return to any alcohol consumption after liver transplant. Thirty-four percent (40/118) of patients with a history of alcohol abuse/dependency relapsed to use of any alcohol after liver transplant. Nine of 25 hypothesized risk factors were predictive of alcohol relapse after liver transplant: absence of hepatocellular carcinoma, tobacco dependence, continued alcohol use after liver disease diagnosis, low motivation for alcohol treatment, poor stress management skills, no rehabilitation relationship, limited social support, lack of nonmedical behavioral consequences, and continued engagement in social activities with alcohol present. Each independent predictor was assigned an Alcohol Relapse Risk Assessment (ARRA) risk value of 1 point, and patients were classified into 1 of 4 groups by ARRA score: ARRA I = 0, ARRA II = 1 to 3, ARRA III = 4 to 6, and ARRA IV = 7 to 9. Patients in the 2 higher ARRA classifications had significantly higher rates of alcohol relapse and were more likely to return to pretransplant levels of drinking. Alcohol relapse rates are moderately high after liver transplant. The ARRA is a valid and practical tool for identifying pretransplant patients with alcohol abuse or dependency at elevated risk of any alcohol use after liver transplant.

    Full Text Available BACKGROUND: In Africa, relapsing fevers are neglected arthropod-borne infections caused by closely related Borrelia species. They cause mild to deadly undifferentiated fever particularly severe in pregnant women. Lack of a tool to genotype these Borrelia organisms limits knowledge regarding their reservoirs and their epidemiology. METHODOLOGY/PRINCIPAL FINDINGS: Genome sequence analysis of Borrelia crocidurae, Borrelia duttonii and Borrelia recurrentis yielded 5 intergenic spacers scattered between 10 chromosomal genes that were incorporated into a multispacer sequence typing (MST approach. Sequencing these spacers directly from human blood specimens previously found to be infected by B. recurrentis (30 specimens, B. duttonii (17 specimens and B. crocidurae (13 specimens resolved these 60 strains and the 3 type strains into 13 species-specific spacer types in the presence of negative controls. B. crocidurae comprised of 8 spacer types, B. duttonii of 3 spacer types and B. recurrentis of 2 spacer types. CONCLUSIONS/SIGNIFICANCE: Phylogenetic analyses of MST data suggested that B. duttonii, B. crocidurae and B. recurrentis are variants of a unique ancestral Borrelia species. MST proved to be a suitable approach for identifying and genotyping relapsing fever borreliae in Africa. It could be applied to both vectors and clinical specimens.

    The purpose of this study was to determine whether hypnosis would be more effective than standard behavioral counseling in helping smokers to remain abstinent. A total of 140 current smokers were enrolled in a randomized controlled smoking cessation trial at an urban Veterans Affairs medical center. Participants (n = 102) who were able to quit for at least 3 days received either a hypnosis or behavioral relapse prevention intervention. Both relapse prevention interventions consisted of two 60 min face-to-face sessions and four 20 min follow-up phone calls (two phone calls per week). At 26 weeks, the validate\\d point-prevalence quit rate was 35% for the hypnosis group and 42% for the behavioral counseling group (relative risk = 0.85; 95% confidence interval: 0.52-1.40). At 52 weeks, the validated quit rate was 29% for the hypnosis group and 28% for the behavioral group (relative risk  = 1.03; 95% confidence interval: 0.56-1.91). It was concluded that hypnosis warrants further investigation as an intervention for facilitating maintenance of quitting.

    2017-06-01

    Multiple sclerosis (MS) is a common inflammatory disease of the central nervous system. Over the last two decades, the number of therapeutic options for the treatment of relapsing remitting MS (RRMS) has been constantly growing, providing new treatment options to patients. Areas covered: Herein, the authors review the recently approved monoclonal antibody daclizumab for the treatment of RRMS. Based on original articles, they discuss its mode of action and evaluate its efficacy and safety profile compared to other available agents. Expert opinion: The IL-2 receptor modulator daclizumab is a new highly effective agent for the treatment of RRMS with novel immunomodulatory properties. Compared to interferon-beta i.m., daclizumab is more effective in reducing relapse rates and MRI activity. However, its use is limited by the risk of autoimmune disorders and hepatotoxicity. Similar to other monoclonal antibodies for RRMS, therapy with daclizumab needs a strict preselection and monitoring of patients based on individual risk benefit assessment. Given its substantial effectiveness, daclizumab can be an attractive option for patients with highly active MS.

    The maxillary horizontal relapse following Le Fort I advancement has been estimated to be 10% to 50%. This retrospective review examines the direct association between the amounts of maxillary advancement and relapse. We hypothesize that the greater the advancement, the greater the relapse amount. Patients with class III skeletal malocclusion underwent maxillary advancement with either a Le Fort I or a Le Fort I with simultaneous mandibular setback (bimaxillary surgery) from 2008 to 2015. Patients were assessed for a history of cleft lip or cleft palate. Patients with known syndromes were excluded. Cephalometric analysis was performed to compare surgical and postsurgical changes. Of 136 patients, 47.1% were males and 61.8% had a history of cleft. The mean surgery age was 18.9 (13.8-23) years and 53.7% underwent a bimaxillary procedure. A representative subgroup of 35 patients had preoperative, immediate postoperative, and an average of 1-year postoperative lateral cephalograms taken. The mean maxillary advancement was 6.3 mm and the horizontal relapse was 1.8 mm, indicating a 28.6% relapse. A history of cleft and amount of maxillary advancement were directly correlated, whereas bone grafting of the maxillary osteotomy sites was inversely correlated with the amount of relapse ( P < .05). Our data suggest positive correlation between amount of maxillary advancement and horizontal relapse as well as a positive correlation between history of cleft and horizontal relapse. Bone grafting of the maxillary osteotomy sites has a protective effect on the relapse.

    Purpose: To examine the costs and benefits of an established practice of routine follow-up in a cohort of patients treated with radiation therapy for early stage Hodgkin's disease. Materials and Methods: We retrospectively examined patterns of follow-up and methods of relapse detection among 709 patients with Ann Arbor Stage I-II Hodgkin's disease treated with sub-total lymphoid irradiation (STLI) or total lymphoid irradiation (TLI) between 1969-1994. We determined the probability of relapse detection for each of 7 routine follow up procedures, compared their relative costs, and determined the impact of each procedure on the likelihood of overall survival following salvage therapy. Results: Relapse has occurred in 157 patients (22%) at a median 1.9 years (range 0-13 years) following treatment. 133 relapses (85%) occurred during the first 5 years of follow. Detailed information concerning the method of relapse detection was available on 107 patients. These 107 patients form the basis of this analysis. Relapse was identified by history (Hx) alone in 55% of patients, physical exam (PE) in 14%, chest x-ray (CXR) in 23% and abdominal x-ray (KUB) in 7%. Only one relapse (1%) was identified by a routine laboratory study - erythrocyte sedimentation rate (ESR). The rate of relapse detection was highest for a combination of history and physical exam (78/10,000 exams) followed by CXR (26/10,000 exams), KUB (10/10,000 exams) and ESR (1/10,000 tests). Complete blood count (CBC) and serum chemistries were never the primary factor in detecting HD relapse. Radiographs accounted for greater than 60% of charges while laboratory studies and physician charges accounted for approximately 20% each. The projected charges (1994 dollars) of relapse detection by routine follow up Hx and PE was [dollar]10,600 compared with [dollar]68,200 for CXR, [dollar]141,800 for KUB and [dollar]156,400 for ESR. 10 year actuarial survival following salvage therapy was 65% overall, 65% for patients in whom

    Opioid dependence relapse is a complex and multidimensional problem, and lack of spiritual well-being is a major concern in opioid addicts. This study was conducted to determine spiritual well-being and factors associated with relapse among opioid addicts. This cross-sectional study was conducted from April 2015 to September 2015. According to purposive sampling, 312 eligible addicted patients were enrolled in the study. The patients had at least an attempt of detoxification in the past six months and referred to an outpatient detoxification clinic in Shahrekord (Southwest, Iran). They completed Paloutzian and Ellison's Spiritual Well-being Scale. A researcher-developed questionnaire consisting of demographic characteristics and 20 questions about associated factors with relapse was administered. Data were analysed by version 16.0 (SPSS Inc.,Chicago, IL) using one-way ANOVA, Pearson's correlation test, chi-square, Friedman test, and student's t-test. The most important factors associated with opioid dependence relapse consist of relation with an addict friend, unemployment, living expenses, family conflicts, and somatic pain. In the present study, 157 patients had never experienced relapse while the mean of relapse in the rest participants was (3.25±1.53) times. Furthermore, the addicted patients with relapse had significantly lower scores of spiritual well-being and its subscales compared with non-relapse patients (pspiritual well-being, family and economical, personal, and occupational factors as crucial factors in opiate addiction relapse.

    Full Text Available Excessive ineffective erythropoiesis in thalassemia intermedia may cause extramedullary hematopoiesis (EMH, resulting in spleen and liver enlargement or masses in several tissues, mainly paravertebrally. Other less frequent locations of diffuse compensatory EMH are kidneys, adrenal glands, breasts, spinal cord, pleura, pericardium, duramater, adipose tissue and skin, although intrathoracic extramedullary hematopoiesis is a rare condition. Management strategies have included radiation and transfusion therapy. Hydroxyurea with transfusion therapy has been associated with clinical regression of EMH in thalassemia. We report an uncommon case of intrathoracic EMH in a patient with beta-thalassemia intermedia, that showed significant recovery with HU therapy.A excessiva eritropoese ineficaz na talassemia pode causar hemato-poese extramedular (HEM, resultando em hepatomegalia, esplenomegalia e massas de tecido hematopoético em diversos tecidos.

    Psychotherapy for sex offenders has only very recently started to develop in France. The French law on compulsory treatment for sex offenders was voted in 1998, and many mental health practitioners are not trained to treat such patients yet. In our ambulatory forensic consultation, sex offenders have been treated since 1992 and group psychotherapy has been offered to them since 1994. Our first therapeutic models were the North-American behavioural-cognitive therapy and Pithers' relapse prevention model. Behavioural-cognitive theory describes paedophilia as an acquired sexual preference maintained by positive reinforcement. Pithers (1990) considered that relapse only occurs in high-risk situations, and that high-risk situations always come after offence precursors. In North America, relapse prevention consists in helping paedophiles spot their high-risk situations and offence precursors, and enhance their skills to cope with such situations or to prevent them. Therapy programs were developed according to these models, aiming to help offenders develop such skills, ie empathy, social skills, cognitive restructuring, self-esteem, etc. Trying to apply these therapy programs in France, our team quickly realised that we would have to adapt them to French culture. On the one hand, behavioural-cognitive theory did not seem satisfactory enough in explaining paedophilic behaviour and paedophilic preference. On the other hand, behavioural-cognitive therapy made patients into children too much and increased resistance. Therapy based on programs seemed too rigid for French patients and therapists, and we often felt we were working on an issue that would have been much more accurate to work on a few sessions earlier, when this issue was spontaneously brought up by a patient. We believe change occurs all the more as issues are worked on at the right moment for the patient. Moreover, on a cultural point of view, we also realised the use of programs in psychotherapy was difficult to

    Full Text Available Addiction to cocaine is a chronic condition characterized by high rates of early relapse. This study builds on efforts to identify neural markers of relapse risk by studying resting state functional connectivity (rsFC in neural circuits arising from the amygdala; a brain region implicated in relapse-related processes including craving and reactivity to stress following acute and protracted withdrawal from cocaine. Whole-brain resting-state fMRI connectivity (6 min was assessed in 45 cocaine-addicted individuals and 22 healthy controls. Cocaine-addicted individuals completed scans in the final week of a residential treatment episode. To approximate preclinical models of relapse-related circuitry separate seeds were derived for the left and right basolateral (BLA and corticomedial (CMA amygdala. Participants also completed the Iowa Gambling Task, Wisconsin Card Sorting Test, Cocaine Craving Questionnaire, Obsessive Compulsive Cocaine Use scale, Temperament and Character Inventory and the NEO-PI-R. Relapse within the first 30 days post-treatment (n = 24 was associated with reduced rsFC between the left CMA and ventromedial prefrontal cortex/rostral anterior cingulate cortex (vmPFC/rACC relative to cocaine-addicted individuals who remained abstinent (non-relapse, n = 21. Non-relapse participants evidenced reduced rsFC between the bilateral BLA and visual processing regions (lingual gyrus/cuneus compared to controls and relapsed participants. Early relapse was associated with fewer years of education but unrelated to trait reactivity to stress, neurocognitive and clinical characteristics or cocaine use history. Findings suggest that rsFC within neural circuits implicated in preclinical models of relapse may provide a promising marker of relapse risk in cocaine-addicted individuals. Future efforts to replicate the current findings and alter connectivity within these circuits may yield novel interventions and improve treatment outcomes.

    Based on conceptual models of addiction and affect regulation, this study examined the mechanisms linking current major depressive syndrome (MDS) and anxiety syndrome (AS) to postpartum smoking relapse. Data were collected in a randomized clinical trial from 251 women who quit smoking during pregnancy. Simple and multiple mediation models of the relations of MDS and AS with postpartum relapse were examined using linear regression, continuation ratio logit models, and a bootstrapping procedure to test the indirect effects. Both MDS and AS significantly predicted postpartum smoking relapse. After adjusting for MDS, AS significantly predicted relapse. However, after adjusting for AS, MDS no longer predicted relapse. Situationally based self-efficacy, expectancies of controlling negative affect by means other than smoking, and various dimensions of primary and secondary tobacco dependence individually mediated the effect of both MDS and AS on relapse. In multiple mediation models, self-efficacy in negative/affective situations significantly mediated the effect of MDS and AS on relapse. The findings underscore the negative impact of depression and anxiety on postpartum smoking relapse and suggest that the effects of MDS on postpartum relapse may be largely explained by comorbid AS. The current investigation provided mixed support for affect regulation models of addiction. Cognitive and tobacco dependence-related aspects of negative and positive reinforcement significantly mediated the relationship of depression and anxiety with relapse, whereas affect and stress did not. The findings emphasize the unique role of low agency with respect to abstaining from smoking in negative affective situations as a key predictor of postpartum smoking relapse. © 2012 American Psychological Association

    Characteristics at clinically isolated syndrome (CIS) examination assist in identification of patient at highest risk of early second attack and could benefit the most from early disease-modifying drugs (DMDs). To examine determinants of second attack and validate a prognostic nomogram for individualised risk assessment of clinical conversion. Patients with CIS were prospectively followed up in the MSBase Incident Study. Predictors of clinical conversion were analysed using Cox proportional hazards regression. Prognostic nomograms were derived to calculate conversion probability and validated using concordance indices. A total of 3296 patients from 50 clinics in 22 countries were followed up for a median (inter-quartile range (IQR)) of 1.92 years (0.90, 3.71). In all, 1953 (59.3%) patients recorded a second attack. Higher Expanded Disability Status Scale (EDSS) at baseline, first symptom location, oligoclonal bands and various brain and spinal magnetic resonance imaging (MRI) metrics were all predictors of conversion. Conversely, older age and DMD exposure post-CIS were associated with reduced rates. Prognostic nomograms demonstrated high concordance between estimated and observed conversion probabilities. This multinational study shows that age at CIS onset, DMD exposure, EDSS, multiple brain and spinal MRI criteria and oligoclonal bands are associated with shorter time to relapse. Nomogram assessment may be useful in clinical practice for estimating future clinical conversion.

    2017-12-01

    Full Text Available Multiple sclerosis (MS is a chronic autoimmune disease of the central nervous system and is characterized by inflammation, demyelination, and axonal loss. Fingolimod is the first oral drug for the treatment of MS approved by the United States Food and Drug Administration, European Union countries, and various other countries. The compound exerts its effect via interaction with lysophospholipid receptors known as sphingosine-1 phosphate receptors. Although fingolimod has a very convenient daily oral dosing, it may cause development of bradycardia at the first dose, macular edema, infection, all of which require attention. Randomized double-blind clinical trials have shown that fingolimod significantly reduces relapse rates and is beneficial in brain magnetic resonance imaging measures when compared with both placebo and intramuscular interferon β-1a. This review describes the characteristics of fingolimod concerning its efficacy, safety, and tolerability in the clinical context of the management of MS

    Metaiodobenzylguanidine (MIBG) has been used for the detection and treatment of neuroectodermal tumors, including neuroblastoma. We report our experience with 131 I-MIBG used diagnostically in neuroblastoma patients with relapse. Thirty-eight studies were performed in 26 patients. There were 24 children (range 3 months-14 years) and two adults. While the study was found to be both sensitive and specific for the presence of disease, there are instances of discordance. False-negative studies were found with a markedly anaplastic tumor and with two mature ganglioneuromas. A bone lesion was negative with 131 I-MIBG, but positive on bone scan. A biopsy confirmed the presence of neuroblastoma. Caution should be exercised when scanning pretreated patients, and perhaps with newly diagnosed patients as well

    2012-02-01

    Relapsing polychondritis (RP) is a rare disorder, often requiring high doses of immunosuppressive therapy to control its potentially life-threatening consequences. The advent of biological agents has added to the armamentarium available to treat RP, but the lack of controlled trials, along with the small numbers of patients and disease heterogeneity means that new therapies are prescribed without the benefits of rigorous clinical research. Thus, information on individual cases is of value in expanding our knowledge of the use of biologic agents in rare conditions. We report on the use of rituximab in a patient who subsequently developed catastrophic aortic incompetence, and we review the literature in relation to the use of this drug in RP.

    Impulsivity is one of the causes of relapse that can affect treatment outcomes. Studies have shown that addiction treatments can reduce impulsivity in drug-dependent individuals. Studies also have suggested that mindfulness is associated with impulsivity. However, no study has investigated the effectiveness of the mindfulness-based intervention on impulsivity in opioid-dependent individuals. This study aimed to compare the effectiveness of mindfulness-based relapse prevention (MBRP) with treatment as usual (TAU) in terms of impulsivity and relapse for methadone-treated patients. The present randomized controlled clinical trial was performed in Kashan, Iran, in 2015. The study population was opioid-dependent patients referred to Maintenance Treatment Centers. Seventy patients were selected by random sampling and were assigned in two groups (MBRP and TAU) randomly. The participants of two groups filled out Barratt impulsivity scale (BIS-11) as a pre-test and 8 weeks later as post-test and 2 months later as a follow-up. Both groups received methadone-therapy. The MBRP group received 8 sessions of group therapy, while the control group did not receive any group psychotherapy session. Finally, data from 60 patients were analyzed statistically. The MBRP group had decreased impulsivity significantly (P relapse frequency (P relapse probability. These findings suggest that MBRP is useful for opioid-dependent individuals with high-level impulsivity, and relapse prevention.

    The prognosis of relapsed Wilms tumor (WT) with diffuse anaplasia is dismal, therefore, novel therapeutic strategies need to be explored. We reported on 2 consecutive cases with relapsed anaplastic WT who presented a partial response after 2 courses of vincristine, irinotecan, and bevacizumab association. This regimen may have a role in the treatment of patients with anaplastic advanced WT.

    Full Text Available Background. Antithyroid drug (ATD treatment occupies the cornerstone therapeutic modality of Graves’ disease (GD with a high relapse rate after discontinuation. This study aimed to assess potential risk factors for GD relapse especially serum interleukin-17 (IL-17 expression. Methods. Consecutive newly diagnosed GD patients who were scheduled to undergo ATD therapy from May 2011 to May 2014 were prospectively enrolled. Risk factors for GD relapse were analyzed by univariate and multivariate Cox proportional hazard analyses. The association between serum IL-17 expression at cessation and GD relapse was analyzed with relapse-free survival (RFS by the Kaplan–Meier survival analysis and log-rank test. Results. Of the 117 patients, 72 (61.5% maintained a remission for 12 months after ATD withdrawal and 45 (38.5% demonstrated GD relapse. The final multivariate Cox analysis indicated elevated IL-17 expression at cessation to be an independent risk factor for GD relapse within 12 months after ATD withdrawal (HR: 3.04, 95% CI: 1.14–7.67, p=0.021. Patients with higher expressions of IL-17 (≥median value at cessation demonstrated a significantly higher RFS than those with lower levels by the Kaplan–Meier analysis and log-rank test (p=0.028. Conclusions. This present study indicated elevated serum IL-17 expression at cessation to be a predictor for GD relapse within 12 months.

    Studies in methamphetamine (METH) abusers showed that the decreases in brain dopamine (DA) function might recover with protracted detoxification. However, the extent to which striatal DA function in METH predicts recovery has not been evaluated. Here we assessed whether striatal DA activity in METH abusers is associated with clinical outcomes. Brain DA D2 receptor (D2R) availability was measured with positron emission tomography and [{sup 11}C]raclopride in 16 METH abusers, both after placebo and after challenge with 60 mg oral methylphenidate (MPH) (to measure DA release) to assess whether it predicted clinical outcomes. For this purpose, METH abusers were tested within 6 months of last METH use and then followed up for 9 months of abstinence. In parallel, 15 healthy controls were tested. METH abusers had lower D2R availability in caudate than in controls. Both METH abusers and controls showed decreased striatal D2R availability after MPH and these decreases were smaller in METH than in controls in left putamen. The six METH abusers who relapsed during the follow-up period had lower D2R availability in dorsal striatum than in controls, and had no D2R changes after MPH challenge. The 10 METH abusers who completed detoxification did not differ from controls neither in striatal D2R availability nor in MPH-induced striatal DA changes. These results provide preliminary evidence that low striatal DA function in METH abusers is associated with a greater likelihood of relapse during treatment. Detection of the extent of DA dysfunction may be helpful in predicting therapeutic outcomes.

    Purpose: To determine which clinical, biological, or treatment-related factors of the first and second primary breast cancers influenced the outcome following contralateral breast carcinoma (CBC). Methods and Materials: By August 1994, 319 of 6406 patients with clinical Stage 0 to III breast carcinoma treated between 1981 and 1987 at Institut Curie had developed a second breast cancer that was diagnosed more than 6 months following ipsilateral breast cancer. Of these 319 patients, 235 had a CBC as the first recurrent event and constitute the study population. Comparisons of first and second breast tumor characteristics were done using Fisher's exact test. Survival distributions from the date of CBC were compared by the log-rank test. Prognostic factors for local relapses, distant relapses, and survival after CBC were assessed by univariate and multivariate analysis using the Cox proportional hazards model. Results: The diagnosis of CBC was more frequently guided by mammographies than for ipsilateral tumors (p 5 years) had no influence on survival. Cox model analysis showed that the risk factors for distant metastases were stage and progesterone receptor levels of the contralateral tumor. The risk of distant failure in CBC was not influenced by the extent of surgery. Conclusions: In this selected population of CBCs as first recurrent events, a follow-up policy based on clinical examination and annual mammography enabled the detection of CBCs at an earlier stage than the primary ipsilateral cancer. The outcome after CBC was determined only by the characteristics of the contralateral tumor. Breast-conserving treatment should be recommended when it is feasible. Adjuvant chemotherapy should be delivered according to the same criteria as the primary tumor

    The present investigation focused on Gamblers Anonymous (GA) members in Ohio to ascertain whether or not spousal participation in Gam-Anon, the companion support group, decreased the gambler's relapse into gambling behavior. A cross-sectional survey of 43 GA members was conducted using a self-administered questionnaire. While no significant difference was found in the relapse of those gamblers with or without a spouse in Gam-Anon, the degree to which the gambler had engaged in other addictive-like behaviors in the past did appear to be related to relapse. Those gamblers who had not relapsed reported significantly more engagement in past addictive-like behaviors (excessive overeating, drinking, and using drugs) than those who had relapsed. Additionally, their spouses had also engaged in addictive-like behaviors in the past. Discussion suggests possible explanations for the findings. Implications are drawn for both outcome measures and research with self-help groups.

    Full Text Available Drug addiction is a chronic illness characterized by high rates of relapse. Relapse to drug use can be triggered by re-exposure to drug-associated cues, stressful events, or the drug itself after a period of abstinence. Pharmacological intervention to reduce the impact of relapse-instigating factors offers a promising target for addiction treatment. Growing evidence has implicated an important role of the orexin/hypocretin system in drug reward and drug-seeking, including animal models of relapse. Here, we review the evidence for the role of orexins in modulating reward and drug-seeking in animal models of addiction and the potential for orexin receptors as specific targets for anti-relapse medication approaches.

    Full Text Available Abstract Background The management of unresectable or metastatic gastrointestinal stromal tumors (GISTs has previously been difficult as they are resistant to conventional chemotherapy and radiation. The development of imatinib mesylate has made a major impact on the management of advanced GISTs. It is apparent that there are sanctuary sites such as the central nervous system where imatinib does not achieve adequate concentrations. We describe the case of a man with metastatic GIST who experienced multiple cerebral relapses of disease while systemic disease progression appeared to be controlled by imatinib. Case presentation A 47-year-old man presented in July 1999 with a jejunal GIST with multiple hepatic metastases. The jejunal primary was resected and after unsuccessful cytoreductive chemotherapy, the liver metastases were also resected in December 1999. The patient subsequently relapsed in August 2001 with symptomatic hepatic, subcutaneous gluteal, left choroidal and right ocular metastases all confirmed on CT and PET scanning. Biopsy confirmed recurrent GIST. MRI and lumbar puncture excluded central nervous system involvement. The patient was commenced on imatinib 400 mg bd in September 2001 through a clinical trial. The symptoms improved with objective PET and CT scan response until December 2002 when the patient developed a right-sided foot drop. MRI scan showed a left parasagittal tumor which was resected and confirmed histologically to be metastatic GIST. Imatinib was ceased pre-operatively due to the trial protocol but recommenced in February 2003 on a compassionate use program. The left parasagittal metastasis recurred and required subsequent re-excision in September 2003 and January 2004. Control of the systemic GIST was temporarily lost on reduction of the dose of imatinib (due to limited drug supply but on increasing the dose back to 800 mg per day, systemic disease was stabilized for a period of time before generalised progression

    Purpose: To determine, in the setting of advanced-stage of Hodgkin lymphoma (HL), whether relapses occur in the irradiated planning target volume and whether the definition of local radiation therapy (RT) used by the German Hodgkin Study Group (GHSG) is adequate, because there is no harmonization of field and volume definitions among the large cooperative groups in the treatment of advanced-stage HL. Methods and Materials: All patients with residual disease of ≥2.5 cm after multiagent chemotherapy (CTX) were evaluated using additional positron emission tomography (PET), and those with a PET-positive result were irradiated with 30 Gy to the site of residual disease. We re-evaluated all sites of disease before and after CTX, as well as the PET-positive residual tumor that was treated in all relapsed patients. Documentation of radiation therapy (RT), treatment planning procedures, and portal images were carefully analyzed and compared with the centrally recommended RT prescription. The irradiated sites were compared with sites of relapse using follow-up computed tomography scans. Results: A total of 2126 patients were enrolled, and 225 patients (11%) received RT. Radiation therapy documents of 152 irradiated patients (68%) were analyzed, with 28 irradiated patients (11%) relapsing subsequently. Eleven patients (39%) had an in-field relapse, 7 patients (25%) relapsed outside the irradiated volume, and an additional 10 patients (36%) showed mixed in- and out-field relapses. Of 123 patients, 20 (16%) with adequately performed RT relapsed, compared with 7 of 29 patients (24%) with inadequate RT. Conclusions: The frequency and pattern of relapses suggest that local RT to PET-positive residual disease is sufficient for patients in advanced-stage HL. Insufficient safety margins of local RT may contribute to in-field relapses.

    Full Text Available Abstract Background Relapsing Plasmodium vivax infection results in significant morbidity for the individual and is a key factor in transmission. Primaquine remains the only licensed drug for prevention of relapse. To minimize relapse rates, treatment guidelines have recently been revised to recommend an increased primaquine dose, aiming to achieve a cumulative dose of ≥6 mg/kg, i.e. ≥420 mg in a 70 kg patient. The aims of this study were to characterize the epidemiology of P. vivax infection imported into Queensland Australia, to determine the rates of relapse, to investigate the use of primaquine therapy, and its efficacy in the prevention of relapse. Methods A retrospective study was undertaken of laboratory confirmed P. vivax infection presenting to the two major tertiary hospitals in Queensland, Australia between January 1999 and January 2011. Primaquine dosing was classified as no dose, low dose ( Results Twenty relapses occurred following 151 primary episodes of P. vivax infection (13.2%. Relapses were confirmed among 3/21 (14.2%, 9/50 (18.0%, 1/54 (1.9% and 7/18 (38.9% of patients administered no dose, low dose, high dose and unknown primaquine dose respectively. High dose primaquine therapy was associated with a significantly lower rate of relapse compared to patients who were prescribed low dose therapy (OR 11.6, 95% CI 1.5-519, p = 0.005. Conclusions Relapse of P. vivax infection is more likely in patients who received low dose primaquine therapy. This study supports the recommendations that high dose primaquine therapy is necessary to minimize relapse of P. vivax malaria.

    Many reports concerning radiation therapy for brain metastasis have been published, and which of the various methods urged by these reports provide optional control is still controversial. According to developing diagnosis of metastasis in CNS, therapeutic problems should be referred. We reviewed 67 patients with small cell lung cancer and brain metastasis who underwent brain irradiation (Ave. 47 Gy/5W), and all 15 patients with brain relapse after the irradiation. Relapsing patterns in this clinical setting were divided into local regrowth in the same lesions and re-metastasis (reseeding) in other regions, by reviewing follow up CT and MRI studies. Total survival among 15 patients with brain relapse and 52 without relapse was longer in the former cases than the later: 1-, and 2-year survival (47/19%, 13/8%) and MST (10.8/5.7 months), from the initial brain irradiation. The concerned significant factors limited in younger age, low value of LDH and improvement of NF. Of the 15 patients with brain relapse, 4 developed local regrowth and 11 did re-metastasis. The period of remission since brain irradiation were 172±94.4 and 393±281 days, respectively. Lower number of brain metastasis and lower value of LDH were shown in re-metastasis patients. At the time of brain relapse, 11 patients had recurrence of carcinomatous meningitis. 4 patients were treated with whole brain re-irradiation. All patients died of cancer, including 12 of relapsing CNS diseases and 3 of primary lesion and hepatic metastasis. Leukoencephalopathy developed in 2 patients. Survival since the brain relapse was 2 to 238 days without significant difference in cases of local regrowth and re-metastasis. According to our data on relapsing pattern of brain metastasis after conventional fractionated brain irradiation with an objective dose of 50 Gy, 75% of brain relapse were re-metastasis, we appreciate this irradiation for initial brain metastasis if limited to the brain.

    Full Text Available BACKGROUND: Despite advances in the treatment of acute leukemia, many patients need to undergo hematopoietic stem cell transplantation. Recent studies show that early lymphocyte recovery may be a predictor of relapse and survival in these patients. OBJECTIVE: To analyze the influence of lymphocyte recovery on Days +30 and +100 post-transplant on the occurrence of relapse and survival. METHODS: A descriptive, retrospective study was performed of 137 under 21-year-old patients who were submitted to hematopoietic stem cell transplantation for acute leukemia between 1995 and 2008. A lymphocyte count 0.3 x 10(9/L were considered adequate. Lymphocyte recovery was also analyzed on Day +100 with < 0.75 x 10(9/Land < 0.75 x 10(9/L being considered inadequate and adequate lymphocyte recovery, respectively. RESULTS: There was no significant difference in the occurrence of relapse between patients with inadequate and adequate lymphocyte recovery on Day +30 post-transplant. However, the transplant-related mortality was significantly higher in patients with inadequate recovery on Day +30. Patients with inadequate lymphocyte recovery on Day +30 had worse overall survival and relapse-free survival than patients with adequate recovery. There was no significant difference in the occurrence of infections and acute or chronic graft-versus-host disease. Patients with inadequate lymphocyte recovery on Day +100 had worse overall survival and relapse-free survival and a higher cumulative incidence of relapse. CONCLUSION: The evaluation of lymphocyte recovery on Day +30 is not a good predictor of relapse after transplant however patients with inadequate lymphocyte recovery had worse overall survival and relapse-free survival. Inadequate lymphocyte recovery on Day +100 is correlated with higher cumulative relapse as well as lower overall survival and relapse-free survival.

    Alcohol consumption levels and alcohol use disorder (AUD) symptoms may serve as easily quantifiable markers for AUD relapse after remission and might help prevention workers identify at-risk individuals. We investigated the predictive value of alcohol consumption and AUD symptoms on relapse. Data are from the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2). We selected 506 people in ≥12-month DSM-5 AUD remission at baseline and assessed their status at 3-year follow-up. AUD symptoms and drinking patterns were assessed using the Composite International Diagnostic Interview 3.0. Time since remission was assessed retrospectively at baseline and ranged from 1 to 48 years. Predictors for relapse were examined using Cox regression analysis. Cumulative AUD relapse rate was 5.6% at 5 years, 9.1% at 10 years and 12.0% at 20 years. Relapse was predicted by both medium (15-28/22-42 drinks weekly for women/men) and high (≥29/43) past alcohol intake, 6+ lifetime AUD symptoms, 'impaired control over use', and at-risk (≥8/15) current intake. The risk of relapse was especially high when medium or high past intake or 6+ lifetime symptoms coincided with current at-risk drinking. Only a minority of people in DSM-5 AUD remission relapsed, but the risk of relapse increased substantially with the presence of at least one of the risk factors. Moreover, at-risk current drinking coupled with other risk factors substantially increased the likelihood of relapse. Therefore, current drinking may provide an adequate reference point for relapse prevention. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Tuberculosis kills more people than any other infectious disease, and new regimens are essential. The primary endpoint for confirmatory phase III trials for new regimens is a composite outcome that includes bacteriological treatment failure and relapse. Culture methodology is critical to the primary trial outcome. Patients in clinical trials can have positive cultures after treatment ends that may not necessarily indicate relapse, which was ascribed previously to laboratory cross-contamination or breakdown of old lesions. Löwenstein-Jensen (LJ) medium was the previous standard in clinical trials, but almost all current and future trials will use the Mycobacteria Growth Indicator Tube (MGIT) system due to its simplicity and consistency of use, which will affect phase III trial results. LJ was used for the definition of the primary endpoint in the REMoxTB trial, but every culture was also inoculated in parallel into the MGIT system. The data from this trial, therefore, provide a unique opportunity to investigate and compare the incidence of false 'isolated positives' in liquid and solid media and their potential impact on the primary efficacy results. All post-treatment positive cultures were reviewed in the REMoxTB clinical trial. Logistic regression models were used to model the incidence of isolated positive cultures on MGIT and LJ. A total of 12,209 sputum samples were available from 1652 patients; cultures were more often positive on MGIT than LJ. In 1322 patients with a favourable trial outcome, 126 (9.5%) had cultures that were positive in MGIT compared to 34 (2.6%) patients with positive cultures on LJ. Among patients with a favourable outcome, the incidence of isolated positives on MGIT differed by study laboratory (p cultures in some patients even after adjusting for laboratory, p cultures, positive MGIT cultures were more likely to be associated with higher grade TB symptoms reported within 7 days either side of sputum collection in patients with an

    The nodal relapse pattern of surgically staged Merkel cell carcinoma (MCC) with/without elective nodal radiotherapy (RT) was studied in a single institution. A total of 51 patients with MCC, 33 % UICC stage I, 14 % II, 53 % III (4 lymph node metastases of unknown primary) were eligible. All patients had surgical staging: 23 patients sentinel node biopsy (SNB), 22 patients SNB followed by lymphadenectomy (LAD) and 6 patients LAD. In all, 94 % of the primary tumors (PT) were completely resected; 57 % of patients received RT, 51 % of known PT sites, 33 % (8/24 patients) regional RT to snN0 nodes and 68 % (17/27 patients) to pN+ nodes, mean reference dose 51.5 and 50 Gy, respectively. Mean follow-up was 6 years (range 2-14 years). A total of 22 % (11/51) patients developed regional relapses (RR); the 5-year RR rate was 27 %. In snN0 sites (stage I/II), relapse occurred in 5 of 14 nonirradiated vs. none of 8 irradiated sites (p = 0.054), resulting in a 5-year RR rate of 33 % versus 0 % (p = 0.16). The crude RR rate was lower in stage I (12 %, 2/17 patients) than for stage II (43 %, 3/7 patients). In stage III (pN+), RR appeared to be less frequent in irradiated sites (18 %, 3/14 patients) compared with nonirradiated sites (33 %, 3/10 patients, p = 0.45) with 5-year RR rates of 23 % vs. 34 %, respectively. Our data suggest that adjuvant nodal RT plays a major role even if the sentinel nodes were negative. Adjuvant RT of the lymph nodes in patients with stage IIa tumors and RT after LAD in stage III tumors is proposed and should be evaluated prospectively. (orig.)

In the United States, CDI escalated in incidence from 1996 to 2005 from 31 to 64/100,000. In 2010, there were 500,000 cases of CDI with an estimated mortality up to 20,000 cases a year. The significance of this problem is evident from the hospital costs of over 3 billion dollars annually. Fecal microbiota transplant (FMT was first described in 1958 and since then about 500 cases have been published in literature in various small series and case reports. This procedure has been reported mainly from centers outside of the United States and acceptance of the practice has been difficult. Recently the US Food and Drug Administration (FDA labeled FMT as a biological drug; as a result, guidelines will soon be required to help establish it as a mainstream treatment. More US experience needs to be reported to popularize this procedure here and form guidelines.Method: We did a retrospective review of our series of patients with relapsing CDI who were treated with FMT over a 3-year period. We present our experience with FMT at a community hospital as a retrospective review and describe our procedure.Results: There were a total of 12 patients who underwent FMT for relapsing C. difficile. Only one patient failed to respond and required a second FMT. There were no complications associated with the transplant and all patients had resolution of symptoms within 48 hours of FMT.Conclusion: FMT is a cheap, easily available, effective therapy for recurrent CDI; it can be safely performed in a

  9. Multimodal Hazard Rate for Relapse in Breast Cancer: Quality of Data and Calibration of Computer Simulation

    Full Text Available Much has occurred since our 2010 report in Cancers. In the past few years we published several extensive reviews of our research so a brief review is all that will be provided here. We proposed in the earlier reports that most relapses in breast cancer occur within 5 years of surgery and seem to be associated with some unspecified manner of surgery-induced metastatic initiation. These events can be identified in relapse data and are correlated with clinical data. In the last few years an unexpected mechanism has become apparent. Retrospective analysis of relapse events by a Brussels anesthesiology group reported that a perioperative NSAID analgesic seems to reduce early relapses five-fold. We then proposed that primary surgery produces a transient period of systemic inflammation. This has now been identified by inflammatory markers in serum post mastectomy. That could explain the early relapses. It is possible that an inexpensive and non-toxic NSAID can reduce breast cancer relapses significantly. We want to take this opportunity to discuss database quality issues and our relapse hazard data in some detail. We also present a demonstration that the computer simulation can be calibrated with Adjuvant-on-line, an often used clinical tool for prognosis in breast cancer.

    Purpose: To report the clinical course of adolescents with medulloblastoma, with specific emphasis on prognosis and pattern of relapse. Methods and Materials: We retrospectively studied the clinical course and outcomes of children aged 10-20 years with medulloblastoma, treated at centers throughout Canada between 1986 and 2003. To better assess time to relapse, a cohort of patients aged 3-20 years at diagnosis was generated. Results: A total of 72 adolescents were analyzed. Five-year overall survival and event-free survival rates were 78.3% ± 5.4% and 68.0% ± 6.2%, respectively. Late relapses occurred at a median of 3.0 years (range, 0.3-6.8 years). In univariate analysis, conventional risk stratification and the addition of chemotherapy to craniospinal radiation did not have prognostic significance. Female patients had improved overall survival (p = 0.007). Time to relapse increased with age in a linear fashion. After relapse, patients faired poorly regardless of treatment modality. Patients who did not receive chemotherapy initially had improved progression-free survival at relapse (p 0.05). Conclusions: Our study suggests that adolescents with medulloblastoma might have a unique prognosis and pattern of relapse, dissimilar to those in younger children. They might benefit from different risk stratifications and prolonged follow-up. These issues should be addressed in future prospective trials

    Relapsed acute lymphoblastic leukemia (ALL) represents a major cause of morbidity and mortality in pediatrics. With contemporary chemotherapy, >85% of patients with newly diagnosed ALL survive. Unfortunately, 20% of these patients will relapse and for these children, outcomes remain poor despite our best known chemotherapy protocols. Most of these children will achieve a second complete remission, but maintaining this remission remains difficult. Because relapsed ALL is such a significant cause of morbidity and mortality, it is the focus of much research interest. Efforts have been made and continue to focus on understanding the underlying biology that drives relapse. The role of hematopoietic stem cell transplantation in relapsed ALL remains unclear, but many clinicians still favor this for high-risk patients given the poor prognosis with current chemotherapy alone. It is important to use new drugs with little cross-resistance in the treatment of relapsed ALL. New classes of agents are currently being studied. We also discuss prognostic factors and the biology of relapsed ALL.

    The aim of the study was to evaluate the role of joint hyperlaxity (by Beighton score) as a protective factor for clubfoot relapse. Patients with idiopathic clubfoot treated with the Ponseti method between January 2004 and December 2012, without other congenital foot deformity, and not previously treated by open surgery were included in either the Relapse group (n = 23) if it was a clubfoot relapse or the Control group (n = 19) if no relapse was noted. Joint laxity was evaluated using the Beighton score at the latest follow-up against the Normal group (n = 22, children matched by sex and age without clubfoot deformity). We found a significantly higher joint laxity in the Control group (4.58, 95% confidence interval [CI]: 2.1-7.06) as compared to the Relapse (3.17, 95% CI: 1.53-4.81, p = 0.032) and Normal (3.14, 95% CI: 1.78-4.5, p = 0.03) groups. The univariate logistic regression showed a 5.28-times increase in the risk of relapse for a Beighton score lower than 4/9 points (odds ratio = 5.28; 95% CI = 1.29-21.5; p = 0.018). Joint hyperlaxity could be a protective factor for clubfoot relapse.

    Relapse of chronic myelogenous leukemia after bone marrow transplantation can be detected by using clinical, cytogenetic, or molecular tools. A modification of the polymerase chain reaction can be used in patients to detect low levels of the BCR-ABL-encoded mRNA transcript, a specific marker for chronic myelogenous leukemia. Early detection of relapse after bone marrow transplantation could potentially alter treatment decisions. The authors prospectively evaluated 19 patients for evidence of molecular relapse, cytogenetic relapse, and clinical relapse after bone marrow transplantation. They used the polymerase chain reaction to detect residual BCR-ABL mRNA in patients followed up to 45 months after treatment and found 4 patients with BCR-ABL mRNA expression following bone marrow transplantation. Fifteen patients did not express detectable BCR-ABL mRNA. All 19 patients remain in clinical remission. In this prospective study of chronic myelogenous leukemia patients treated with bone marrow transplantation, molecular relapse preceded cytogenetic relapse in those patients who persistently express BCR-ABL mRNA. They recommend using standard clinical and cytogenetic testing to make patient care decisions until further follow-up determines the clinical outcome of those patients with residual BCR-ABL mRNA transcripts detected by polymerase chain reaction

  14. Multiple-clone activation of hypnozoites is the leading cause of relapse in Plasmodium vivax infection.

    Directory of Open Access Journals (Sweden)

    Flávia Carolina F de Araujo

    Full Text Available BACKGROUND: Plasmodium vivax infection is characterized by a dormant hepatic stage, the hypnozoite that is activated at varying periods of time after clearance of the primary acute blood-stage, resulting in relapse. Differentiation between treatment failure and new infections requires characterization of initial infections, relapses, and clone multiplicity in vivax malaria infections. METHODOLOGY/PRINCIPAL FINDINGS: Parasite DNA obtained from primary/relapse paired blood samples of 30 patients with P. vivax infection in Brazil was analyzed using 10 molecular markers (8 microsatellites and MSP-1 blocks 2 and 10. Cloning of PCR products and genotyping was used to identify low-frequency clones of parasites. We demonstrated a high frequency of multiple-clone infections in both primary and relapse infections. Few alleles were identified per locus, but the combination of these alleles produced many haplotypes. Consequently, the majority of parasites involved in relapse showed haplotypes that were distinct from those of primary infections. Plasmodium vivax relapse was characterized by temporal variations in the predominant parasite clones. CONCLUSIONS/SIGNIFICANCE: The high rate of low frequency alleles observed in both primary and relapse infections, along with temporal variation in the predominant alleles, might be the source of reported heterologous hypnozoite activation. Our findings complicate the concept of heterologous activation, suggesting the involvement of undetermined mechanisms based on host or environmental factors in the simultaneous activation of multiple clones of hypnozoites.

    Theoretically, cue exposure treatment should be able to prevent relapse by extinguishing conditioned drug responding (e.g. cue-elicited craving). According to contemporary learning theory, though, extinction does not eliminate conditioned responding. Analogous cue exposure with response prevention (CERP) as a treatment of addictive behavior might not eliminate the learned relation between drug-related cues and drug use. This does not necessarily mean that cue exposure cannot successfully prevent relapse. Various suggestions for increasing the efficacy of cue exposure treatment are being discussed from a contemporary learning theory perspective. It is suggested that cue exposure treatment incorporating retrieval cues can be a beneficial treatment in preventing relapse of addictive behavior.

    Despite recent advances in reducing therapy-related mortality after allogeneic stem cell transplantation (alloSCT) relapse remains the major cause of treatment failure and little progress has been achieved in the last decades. At the 3rd International Workshop on Biology, Prevention, and Treatment of Relapse held in Hamburg/Germany in November 2016 international experts presented and discussed recent developments in the field. Here, the potential of cellular therapies including unspecific and specific T cells, genetically modified T cells, CAR-T cells, NK-cells, and second allografting in prevention and treatment of relapse after alloSCT are summarized.

    Ten patients with newly diagnosed, advanced prostatic cancer were treated with radiotherapy and hormone therapy to improve tumor control and survival. Eight patients with hormonally relapsed prostatic cancer were treated with radiotherapy to improve their quality of life. Local control of the tumor was achieved in 9 of 10 patients with newly diagnosed, advanced prostatic cancer. Five of eight patients with hormonally relapsed prostatic cancer obtained improved quality of life. Combined radiotherapy and hormone therapy were effective in the treatment of newly diagnosed, advanced prostatic cancer, and radiotherapy was useful for improving the quality of life of patients with hormonally relapsed prostatic cancer.

    Full Text Available A 25-year-old man was diagnosised subcutaneous panniculitis-like T-cell lymphoma (SPTCL through biopsy of a nodule from the anterior chest. After the treatment with prednisone 90 mg 3 weeks and tapered off in 1 month, the disease released, but relapsed together with symptions of hemophagocytic syndrome eight months after the termination of prednisone. CHOEP recipe was given but with unsatisfactory result until cyclosporine was prescribed. Cyclosporine was removed 6 months later. There is no evidence of clinical relapse 1 year later. This case suggest that cyclosporine could be a selectable treatment even in relapsed SPTCL.

    Full Text Available Background. Even though Hodgkin lymphoma is a highly curable disease, some of the patients have either a refractory disease or experience a relapse following a successful primary therapy. Durable responses and remissions in patients with relapsed or refractory disease may be achieved in approximately one-half with salvage chemotherapy followed by high dose chemotherapy (HDT and autologous hematopoietic cell rescue (SCT. On the other hand, patients who relapse after HDT and autologous SCT or those who have failed at least two prior multi-agent chemotherapy regimens and are not candidates for HDT have limited treatment options.

    Full Text Available Multiple sclerosis (MS is an immune-mediated disorder; however, little is known about the triggering factors of the abnormal immune response. Different viruses from the herpes family have been mentioned as potential participants. Here, we review the evidences that support the association of varicella zoster virus (VZV with MS. Epidemiological studies from geographical areas, where incidence of MS has increased in recent decades, pointed out a high frequency of varicella and zoster in the clinical antecedents of MS patients, and also laboratory investigations have found large quantities of DNA from VZV in leucocytes and cerebrospinal fluid of MS patients restricted to the ephemeral period of MS relapse, followed by disappearance of the virus during remission. The above observations and the peculiar features of VZV, mainly characterized by its neurotropism and long periods of latency followed by viral reactivation, support the idea on the participation of VZV in the etiology of MS. However, as with reports from studies with other viruses, particularly Epstein Barr virus, conflicting results on confirmatory studies about the presence of viral gene products in brain tissue indicate the need for further research on the potential participation of VZV in the etiology of MS.

    Laryngotracheal involvement in relapsing polychondritis (RP) is rare. However, it is one of the most common causes of death in this patient population. We present three patients who primarily presented with laryngeal manifestations of RP and a novel treatment option for bamboo nodules. Retrospective chart review and comprehensive review of the literature. Two patients first presented to an otolaryngologist because of hoarseness and chronic cough that eventually progressed to dyspnea upon exertion. Laryngeal examination revealed subglottic stenoses. Upon rheumatologic workup both were diagnosed with RP. After treatment with steroids and immunosuppressive drugs, one of the patient's laryngeal symptoms improved, whereas the other required dilation procedures. Neither patient had classic auricular or nasal symptoms upon initial presentation. The third patient was being treated for spasmodic dysphonia and was noted to have bamboo nodules with accompanying dysphonia. Rheumatologic workup revealed RP and systemic treatment ensued. Unfortunately, her symptoms of hoarseness persisted despite systemic treatment. A pulsed-potassium-titanyl-phosphate (KTP) laser was applied to the bilateral bamboo nodules, which eventually caused resolution of her vocal fold lesions and dysphonia. We present three patients with RP, all of whom sought health care by an otolaryngologist primarily. Awareness of this disease entity and the possibility for early laryngeal involvement is crucial for proper care of those with this life-threatening disease. Copyright © 2012 The Voice Foundation.

    Full Text Available Lymphedema (LE is a chronic medical condition characterized by lymphatic fluid retention, resulting in tissue swelling. Cancer treatments involving lymph nodes can damage lymph drainage routes, causing accumulation of lymph fluid in the interstitial tissue of related limbs and body areas and secondary LE.  Basically, the LE has a negative impact on physical and mental quality of life. Moreover, 0.07-0.04% of long term survivors (most patients undergone mastectomy can develop the Stewart-Treves syndrome,  a rare and aggressive multifocal lymphangiosarcoma arising within the LE region. Here we describe a   45-year-old woman  with a massive LE of the left arm,  as a consequence of previous breast cancer,  who  was diagnosed after 4 years  of stage IV mantle cell lymphoma (MCL . The patient after obtaining complete remission with chemotherapy and ABMT  relapsed of MCL in lymphedema site.

    Relapsed/refractory acute lymphoblastic leukemia (ALL) has a low remission rate after chemotherapy, a high relapse rate and poor long-term survival even when allogeneic hematopoietic stem cell transplantation (allo-HSCT) is performed. Chimeric antigen receptors redirected T cells (CAR-T cells) can enhance disease remission with a favorable outcome for relapsed/refractory ALL, though some cases quickly relapsed after CAR-T cell treatment. Thus, treatment with CAR-T cells followed by allo-HSCT may be the best way to treat relapsed/refractory ALL. In this review, we first discuss the different types of CAR-T cells. We then discuss the treatment of relapsed/refractory ALL using only CAR-T cells. Finally, we discuss the use of CAR-T cells, followed by allo-HSCT, for the treatment of relapsed/refractory ALL.

    Despite decades of research on neurobiological mechanisms of psychostimulant addiction, the only effective treatment for many addicts is contingency management, a behavioral treatment that uses alternative non-drug reward to maintain abstinence. However, when contingency management is discontinued, most addicts relapse to drug use. The brain mechanisms underlying relapse after cessation of contingency management are largely unknown, and, until recently, an animal model of this human condition did not exist. Here we used a novel rat model, in which the availability of a mutually exclusive palatable food maintains prolonged voluntary abstinence from intravenous methamphetamine self-administration, to demonstrate that the activation of monosynaptic glutamatergic projections from anterior insular cortex to central amygdala is critical to relapse after the cessation of contingency management. We identified the anterior insular cortex-to-central amygdala projection as a new addiction- and motivation-related projection and a potential target for relapse prevention.

    For many years Malaysia faced the drug addiction issues. The most serious case is relapse phenomenon among treated drug addict (drug addict who have under gone the rehabilitation programme at Narcotic Addiction Rehabilitation Centre, PUSPEN). Thus, the main objective of this study is to find the most significant factor that contributes to relapse to happen. The binary logistic regression analysis was employed to model the relationship between independent variables (predictors) and dependent variable. The dependent variable is the status of the drug addict either relapse, (Yes coded as 1) or not, (No coded as 0). Meanwhile the predictors involved are age, age at first taking drug, family history, education level, family crisis, community support and self motivation. The total of the sample is 200 which the data are provided by AADK (National Antidrug Agency). The finding of the study revealed that age and self motivation are statistically significant towards the relapse cases..

    Research on exercise identity (EXID) indicates that it is related to negative affect when exercisers are inconsistent or relapse. Although identity theory suggests that causal attributions about this inconsistency elicit negative self-conscious emotions of shame and guilt, no EXID studies have examined this for exercise relapse. Weiner's attribution-based theory of interpersonal motivation (2010) offers a means of testing the attribution-emotion link. Using both frameworks, we examined whether EXID and attributional properties predicted negative emotions for exercise relapse. Participants (n = 224) read an exercise relapse vignette, and then completed EXID, attributions, and emotion measures. Hierarchical multiple regression models using EXID and the attributional property of controllability significantly predicted each of shame and guilt, R² adjusted = .09, ps ≤ .001. Results support identity theory suggestions and Weiner's specific attribution-emotion hypothesis. This first demonstration of an interlinking of EXID, controllability, and negative self-conscious emotions offers more predictive utility using complementary theories than either theory alone.

    Background For patients with Graves’ disease (GD), the primary goal of antithyroid drug therapy is to temporarily restore the patient to the euthyroid state and wait for a subsequent remission of the disease. This study sought to identify the predictive markers for the relapse of disease. Methods To do this, we studied 262 GD patients with long enough follow-up after drug withdrawal to determine treatment outcome. The patients were divided into three groups by time of relapse: early relapse group (n = 91) had an early relapse within 9 months, late relapse group (n = 65) had a relapse between 10 and 36 months, and long-term remission group (n = 106) were either still in remission after at least 3 years or relapsed after 3 years of drug withdrawal. We assessed the treatment outcome of 23 SNPs of costimulatory genes, phenotype and smoking habits. We used permutation to obtain p values for each SNP as an adjustment for multiple testing. Cox proportional hazards models was performed to assess the strength of association between the treatment outcome and clinical and laboratory variables. Results Four SNPs were significantly associated with disease relapse: rs231775 (OR 1.96, 95% CI 1.18–3.26) at CTLA-4 and rs745307 (OR 7.97, 95% CI 1.01–62.7), rs11569309 (OR 8.09, 95% CI 1.03–63.7), and rs3765457 (OR 2.60, 95% CI 1.08–6.28) at CD40. Combining risk alleles at CTLA-4 and CD40 improved the predictability of relapse. Using 3 years as the cutoff point for multivariate analysis, we found several independent predictors of disease relapse: number of risk alleles (HR 1.30, 95% CI 1.09–1.56), a large goiter size at the end of the treatment (HR 1.30, 95% CI 1.05–1.61), persistent TSH-binding inhibitory Ig (HR 1.64, 95% CI 1.15–2.35), and smoking habit (HR 1.60, 95% CI 1.05–2.42). Conclusion Genetic polymorphism of costimulatory genes, smoking status, persistent goiter, and TSH-binding inhibitory Ig predict disease relapse. PMID:24783027

    Clear cell sarcoma of the kidney (CCSK) is an uncommon paediatric renal tumour. Relapses occur in about 15% of the patients. Since detailed clinical information on relapsed CCSK is scarce, the current study aims to describe outcome of patients with relapsed CCSK treated according to recent European protocols. We analysed prospectively collected data of all CCSK patients who developed a relapse after complete remission at the end of primary treatment, entered onto SIOP and AIEOP trials between 1992 and 2012. Thirty-seven of 237 CCSK patients (16%) treated according to SIOP and AIEOP protocols developed a relapse. Median time from initial diagnosis to relapse was 17 months (range, 5.5 months - 6.6 years). Thirt-five out of thirty-seven relapses (95%) were metastatic; the most common sites of relapse were the brain (n=13), lungs (n=7) and bone (n=5). Relapse treatment consisted of chemotherapy (n=30), surgery (n=19) and/or radiotherapy (n=18), followed by high-dose chemotherapy and autologous bone marrow transplantation (ABMT) in 14 patients. Twenty-two out of thirty-seven patients (59%) achieved a second complete remission (CR); 15 of whom (68%) developed a second relapse. Five-year event-free survival (EFS) after relapse was 18% (95% CI: 4%-32%), and 5-year overall survival (OS) was 26% (95% CI: 10%-42%). In this largest series of relapsed CCSK patients ever described, overall outcome is poor. Most relapses are metastatic and brain relapses are more common than previously recognised. Intensive treatment aiming for local control, followed by high dose chemotherapy and ABMT, seems to be of benefit to enhance survival. Novel development of targeted therapy is urgently required.

    The authors evaluated a sequential treatment strategy of fluoxetine and relapse-prevention cognitive-behavioral therapy (CBT) to determine effects on remission and relapse in youths with major depressive disorder. Youths 8-17 years of age with major depression were treated openly with fluoxetine for 6 weeks. Those with an adequate response (defined as a reduction of 50% or more on the Children's Depression Rating Scale-Revised [CDRS-R]) were randomly assigned to receive continued medication management alone or continued medication management plus CBT for an additional 6 months. The CBT was modified to address residual symptoms and was supplemented by well-being therapy. Primary outcome measures were time to remission (with remission defined as a CDRS-R score of 28 or less) and rate of relapse (with relapse defined as either a CDRS-R score of 40 or more with a history of 2 weeks of symptom worsening, or clinical deterioration). Of the 200 participants enrolled in acute-phase treatment, 144 were assigned to continuation treatment with medication management alone (N=69) or medication management plus CBT (N=75). During the 30-week continuation treatment period, time to remission did not differ significantly between treatment groups (hazard ratio=1.26, 95% CI=0.87, 1.82). However, the medication management plus CBT group had a significantly lower risk of relapse than the medication management only group (hazard ratio=0.31, 95% CI=0.13, 0.75). The estimated probability of relapse by week 30 was lower with medication management plus CBT than with medication management only (9% compared with 26.5%). Continuation-phase relapse-prevention CBT was effective in reducing the risk of relapse but not in accelerating time to remission in children and adolescents with major depressive disorder.

    The present study was designed to examine the influence of suicidality on relapse in alcohol-dependent patients. Specifically, a lifetime suicide attempt at baseline was used to predict relapse in the year after treatment. Also, the unique contribution of impulsive suicide attempts was examined. A total of 154 patients with alcohol dependence, consecutively admitted to four addiction treatment facilities in Warsaw, Poland participated in the study. Of the 154 eligible patients, 118 (76.6%) completed a standardized follow-up assessment at 12 months. Previous suicide attempts were common in adults treated for alcohol dependence with 43% patients in the present sample reporting an attempt at some point during their lifetime. Additionally, more than 62% of those with a lifetime suicide attempt reported making an impulsive attempt. Lifetime suicide attempts were not associated with post-treatment relapse (chi-square=2.37, d.f.=1, p=0.124). However, impulsive suicide attempts strongly predicted relapse (OR=2.81, 95% CI=1.13-6.95, p=0.026) and time to relapse (OR=2.10, 95% CI=1.18-3.74, p=0.012) even after adjusting for other measures of baseline psychopathology, depression, impulsivity, hopelessness and alcohol use severity. This study is the first to document the relationship between pre-treatment impulsive suicide attempts and higher likelihood of post-treatment relapse in alcohol-dependent patents. Clinicians should routinely conduct an assessment for previous suicide attempts in patients with alcohol use disorders, and when impulsive suicidality is reported, they should recognize the increased risk for relapse and formulate their patients' treatment plans accordingly with the goals of reducing both alcoholic relapse and suicide rates.

    Purpose: To evaluate the patterns and timing of initial recurrence in patients with Hodgkin's lymphoma (HL) who subsequently underwent high-dose chemotherapy with autologous stem cell transplantation to enhance our understanding of the natural history of this disease and its modern treatment strategies and to direct approaches to disease surveillance. Methods and Materials: The records of 69 patients with HL who had undergone high-dose chemotherapy with autologous stem cell transplantation in our center between May 1992 and June 2006 were analyzed. The initial diagnosis had been made between April 1982 and January 2005 at a median patient age of 33 years (range, 19-65). The patients were segregated according to the initial stage (Stage I-II vs. III-IV). Results: Early-stage HL patients developed a relapse at a median of 2.1 years (range, 0.5-10.3), with 91% of relapses at the initial disease site, 71% of which (65% overall) were only in previously involved sites. Advanced-stage HL patients developed a relapse at a median of 1.5 years (range, 0.6-10.5), with 97% at the initial site, 71% of which (69% overall) were only in previously involved sites. Single-site relapses occurred in 47% of early- vs. 26% of advanced-stage patients, and extranodal relapses occurred in 12% of early- vs. 31% of advanced-stage patients. Conclusions: Almost all patients with HL who develop relapse and subsequently undergo high-dose chemotherapy with autologous stem cell transplantation initially developed recurrence in previously involved disease sites. Early-stage HL relapses often occurred in single sites, and advanced-stage disease relapses were more likely in multiple and extranodal sites. The interval to recurrence was brief, suggesting that the frequency of screening should be the greatest in the early post-therapy years.

  7. Are there clinically useful predictors and early warning signs for pending relapse?

    Despite the availability of effective long-term treatment strategies in schizophrenia, relapse is still common. Relapse prevention is one of the major treatment objectives, because relapse represents burden and costs for patients, their environment, and society and seems to increase illness progression at the biological level. Valid predictors for relapse are urgently needed to enable more individualized recommendations and treatment decisions to be made. Mainly recent evidence regarding predictors and early warning signs of relapse in schizophrenia was reviewed. In addition, data from the first-episode (long-term) study (FES; Gaebel et al., 2007, 2011) performed within the German Research Network on Schizophrenia were analyzed. On the basis of FES data, premorbid adjustment, residual symptoms and some side effects are significant predictors. Although a broad spectrum of potential parameters has been investigated in several other studies, only a few and rather general valid predictors were identified consistently. Data of the FES also indicated that predictive power could be enhanced by considering interacting conjunctions, as suggested by the Vulnerability-Stress-Coping model. Prospective studies, however, are rare. In addition, prodromal symptoms as course-related characteristics likewise investigated in the FES add substantially to early recognition of relapse and may serve as early warning signs, but prognosis nevertheless remains a challenge. Comprehensive and well-designed studies are needed to identify and confirm valid predictors for relapse in schizophrenia. In this respect, broadly accepted and specifically defined criteria for relapse would greatly facilitate comparison of results across studies. © 2013 Elsevier B.V. All rights reserved.

    A case of chronic relapsing pancreatitis presenting in an 8-year-old African Jamaican girl is outlined. Aggressive supportive management failed to control pain and vomiting. The Puestow Procedure effectively procedure aborted these symptoms. The use of the Puestow procedure should not be inordinately delayed in chronic relapsing pancreatitis if symptoms persist, since it may not only control pain but also halt declining pancreatic function.

    The aim of the present work was to evaluate the usefulness of CA-125 normalized in time area under the curve (CA-125 AUC) to signalise epithelial ovarian cancer relapse. Data from a hundred and eleven patients were submitted to two different approaches based on CA-125 AUC increase values to predict patient relapse. In Criterion A total CA-125 AUC normalized in time value (AUC(i)) was compared with the immediately previous one (AUC(i-1)) using the formulae AUC(i) > or = F * AUC(i-1) (several F values were tested) to find the appropriate close related increment associated to patient relapse. In Criterion B total CA-125 AUC normalised in time was calculated and several cut-off values were correlated with patient relapse prediction capacity. In Criterion A the best accuracy was achieved with a factor (F) of 1.25 (increment of 25% from the previous status), while in Criterion B the best accuracies were achieved with cut-offs of 25, 50, 75 and 100 IU/mL. The mean lead time to relapse achieved with Criterion A was 181 days, while with Criterion B they were, respectively, 131, 111, 63 and 11 days. Based on our results we believe that conjugation and sequential application of both criteria in patient relapse detection should be highly advisable. CA-125 AUC rapid burst in asymptomatic patients should be firstly evaluated using Criterion A with a high accuracy (0.85) and with a substantial mean lead time to relapse (181 days). If a negative answer was obtained then Criterion B should performed to confirm the absence of relapse.

    Patients on surveillance for clinical stage I (CSI) testicular cancer are counseled regarding their baseline risk of relapse. The conditional risk of relapse (cRR), which provides prognostic information on patients who have survived for a period of time without relapse, have not been determined for CSI testicular cancer. To determine cRR in CSI testicular cancer. We reviewed 1239 patients with CSI testicular cancer managed with surveillance at a tertiary academic centre between 1980 and 2014. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: cRR estimates were calculated using the Kaplan-Meier method. We stratified patients according to validated risk factors for relapse. We used linear regression to determine cRR trends over time. At orchiectomy, the risk of relapse within 5 yr was 42.4%, 17.3%, 20.3%, and 12.2% among patients with high-risk nonseminomatous germ cell tumor (NSGCT), low-risk NSGCT, seminoma with tumor size ≥3cm, and seminoma with tumor size testicular cancer is very low. Consideration should be given to adapting surveillance protocols to individualized risk of relapse based on cRR as opposed to static protocols based on baseline factors. This strategy could reduce the intensity of follow-up for the majority of patients. Our study is the first to provide data on the future risk of relapse during surveillance for clinical stage I testicular cancer, given a patient has been without relapse for a specified period of time.

    The results of several studies suggest that there may be common neurocircuits regulating drug-seeking behaviors. Common biological pathways regulating drug-seeking would explain the phenomenon that seeking for 1 drug can be enhanced by exposure to another drug of abuse. The objective of this study was to assess the time course effects of acute cocaine administration on ethanol (EtOH) seeking and relapse. Alcohol-preferring (P) rats were allowed to self-administer 15% EtOH and water. EtOH-seeking was assessed through the use of the Pavlovian spontaneous recovery (PSR) model, while EtOH-relapse drinking was assessed through the use of the alcohol-deprivation effect. Cocaine (0, 1, or 10 mg/kg), injected immediately, 30 minutes, or 4 hours prior to the first PSR testing session, dose-dependently increased responding on the EtOH lever compared to extinction responses and responding by saline controls. Under relapse conditions, cocaine given immediately prior to the relapse session had no effect (1 mg/kg) or reduced responding (10 mg/kg). In contrast, cocaine given 4 hours prior to the relapse session markedly enhanced EtOH responding compared to saline. The enhanced expression of EtOH-seeking and EtOH-relapse behaviors may be a result of a priming effect of cocaine on neuronal circuits mediating these behaviors. The effect of cocaine on EtOH-relapse drinking is indicative of the complex interactions that can occur between drugs of abuse; production of conflicting behaviors (immediate), and priming of relapse/seeking (4-hour delay).

    Purpose: There is evidence that computed tomography (CT) and positron emission tomography (PET) imaging metrics are prognostic and predictive in nonsmall cell lung cancer (NSCLC) treatment outcomes. However, few studies have explored the use of standardized uptake value (SUV)-based image features of nodal regions as predictive features. The authors investigated and compared the use of tumor and node image features extracted from the radiotherapy target volumes to predict relapse in a cohort of NSCLC patients undergoing chemoradiation treatment. Methods: A prospective cohort of 25 patients with locally advanced NSCLC underwent 4DPET/4DCT imaging for radiation planning. Thirty-seven image features were derived from the CT-defined volumes and SUVs of the PET image from both the tumor and nodal target regions. The machine learning methods of logistic regression and repeated stratified five-fold cross-validation (CV) were used to predict local and overall relapses in 2 yr. The authors used well-known feature selection methods (Spearman’s rank correlation, recursive feature elimination) within each fold of CV. Classifiers were ranked on their Matthew’s correlation coefficient (MCC) after CV. Area under the curve, sensitivity, and specificity values are also presented. Results: For predicting local relapse, the best classifier found had a mean MCC of 0.07 and was composed of eight tumor features. For predicting overall relapse, the best classifier found had a mean MCC of 0.29 and was composed of a single feature: the volume greater than 0.5 times the maximum SUV (N). Conclusions: The best classifier for predicting local relapse had only tumor features. In contrast, the best classifier for predicting overall relapse included a node feature. Overall, the methods showed that nodes add value in predicting overall relapse but not local relapse.

    1995-01-01

    Purpose/Objective: Nasopharyngeal carcinoma (NPC) is not a common malignancy of the head and neck in the United States and presents a great challenge to the radiation oncologists in this country. Its management is radiotherapeutic and technically demanding and calls for careful treatment techniques to include the primary and the lymphatic drainage areas to high doses while sparing the neighboring organs such as the spinal cord, eyes, temporal lobes and midrain. This refresher course will review the clinical course, pattern of spread with manifestations of various neurologic syndromes of the disease. The radiotherapeutic management of primary lesion will be discussed in detail including the treatment techniques, placement of the irradiation portals, dose levels, etc. Treatment results as reported in the literature as well as those achieved at the MGH will be presented. Special emphasis will be placed on the routine use of intracavitary implant to boost the primary site and its technical aspects. Relapsed NPC after previous radiation therapy presents a difficult problem in management, but can be re-irradiated with occasional success by observing careful technique and fractionated intracavitary brachytherapy and the local control rates will be briefly covered. Recurrent disease in the neck will be managed by neck dissection. Xerostomia is undesirable and common sequelae following radical radiation therapy for NPC. Efforts are being made to decrease its magnitude by using higher energies of photons, i.e. 10 MV to spare a portion of the parotid glands with some promising results. Because of the unique location of the primary lesion, currently a modified BID program (MBID) is used and its techniques and treatment concept are discussed

    Many smokers attempt to quit smoking, but very few succeed. To identify the timing and risk factors involved in smoking relapse. We conducted a prospective cohort study among staff in two public universities in Malaysia. Behavioural therapy with free nicotine replacement therapy was given as treatment. Participants were followed up for 6 months. Relapse was defined as returning to smoking after having quit for at least 24 h. Of 185 smokers who volunteered to participate, 120 achieved at least 24-h abstinence, and 80% of these relapsed within 2 months. Compared to participants who attended a single smoking cessation session, participants who attended three sessions had a lower likelihood of relapse within 6 months of quitting. In contrast, smokers with a much longer exposure to cigarette smoking in the workplace (>3 h per week) had a greater chance of relapse compared to those with no exposure. Frequent attendance at clinic sessions and less exposure to other people smoking in the workplace can potentially reduce the likelihood of relapse among smokers who have recently quit.

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

    2016-01-15

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

    Ghrelin and peptide YY (PYY) during ad libitum smoking have been associated with decreased reported craving (ghrelin) and increased positive affect (PYY), and higher baseline ghrelin levels predicted subsequent increased risk of smoking relapse. The current study assessed PYY and ghrelin during ad libitum smoking and again after the initial 48h of a smoking cessation attempt. The data compared smokers who abstained for 28days (n=37), smokers who relapsed (n=54), and nonsmokers (n=37). Plasma samples and subjective measures assessing craving and mood were collected at the beginning of each session. Results showed that relapsers experienced greater levels of distress (ps <0.01). While nonsmokers and abstainers showed no change in ghrelin across the initial 48h, relapsers declined (p <0.01). With PYY, relapsers increased (p <0.05) across the early abstinent phase. PYY and ghrelin may be useful predictors of relapse, specifically in reference to early withdrawal. Copyright © 2017. Published by Elsevier B.V.

    The purpose of this study was to identify whether heroin relapse is associated with changes in the functional connectivity of the default mode network (DMN) during methadone maintenance treatment (MMT). Resting-state functional magnetic resonance imaging (fMRI) data of chronic heroin relapsers (HR) (12 males, 1 female, age: 36.1 ± 6.9 years) and abstainers (HA) (11males, 2 female; age: 42.1 ± 8.1 years) were investigated with an independent component analysis to address the functional connectivity of their DMN. Group comparison was then performed between the relapsers and abstainers. Our study found that the left inferior temporal gyrus and the right superior occipital gyrus associated with DMN showed decreased functional connectivity in HR when compared with HA, while the left precuneus and the right middle cingulum had increased functional connectivity. Mean intensity signal, extracted from left inferior temporal gyrus of HR patients, showed a significant negative correlation corresponding to the degree of heroin relapse. These findings suggest that altered functional connectivity of DMN may contribute to the potential neurobiological mechanism(s) of heroin relapse and have a predictive value concerning heroin relapse under MMT.

    Full Text Available ABSTRACT Objective The objective of the present study was to evaluate 88 adolescent crack users referred to hospitalization and to follow them up after discharge to investigate relapse and factors associated with treatment. Methods Cohort (30 and 90 days after discharge from a psychiatric hospital and a rehab clinic for treatment for chemical dependency in Porto Alegre between 2011 and 2012. Instruments: Semi-structured interview, conducted to evaluate the sociodemographic profile of the sample and describe the pattern of psychoactive substance use; Crack Use Relapse Scale/CURS; Questionnaire Tracking Users to Crack/QTUC; K-SADS-PL. Results In the first follow-up period (30 days after discharge, 65.9% of participants had relapsed. In the second follow-up period (90 days after discharge, 86.4% of participants had relapsed. Conclusion This is one of the first studies that show the extremely high prevalence of early relapse in adolescent crack users after discharge, questioning the cost/benefit of inpatient treatment for this population. Moreover, these results corroborate studies which suggested, young psychostimulants users might need tailored intensive outpatient treatment with contingency management and other behavioral strategies, in order to increase compliance and reduce drug or crime relapse, but this specific therapeutic modality is still scarce and must be developed in Brazil.

    Full Text Available High rate of relapse after apparently successful treatment is a common problem facing with most approaches to treatment of drug dependency. This has led to the development of a variety of strategies for relapse prevention. Among these, Marlatt’s cognitive – behavioural model has received a good deal of attention. It is based on two major axes: Identification of warning sings and development of necessary skills for coping with risk situations. In fact, client’s perception relating to their abilities to cope with high - risk situations can lead to lapse. Relapes is a function of client’s reaction to this initial lapes.Since formal training for addiction counsellors typically includes instruction on Marlatt’s relapes taxonomy and intervention strategies have been designed based on his classification systems of high – risk stimuli, it is nececsary for addiction counsellors to become familiar with this system. This paper presents an overview of Marlatts taxonomy of high – risk situations for relapse and his approach to relapse prevention. Special attention is given to definition of relapse, stages of relaps and relapse prevention strategies.

  3. Multiple sclerosis, relapses, and the mechanism of action of adrenocorticotropic hormone (ACTH

    Full Text Available Relapses in multiple sclerosis (MS are disruptive and frequently disabling for patients, and their treatment is often a challenge to clinicians. Despite progress in the understanding of the pathophysiology of MS and development of new treatments for long-term management of MS, options for treating relapses have not changed substantially over the past few decades. Corticosteroids, a component of the HPA axis that modulate immune responses and reduce inflammation, are currently the mainstay of relapse treatment. Adrenocorticotropic hormone (ACTH gel is another treatment option. Although it has long been assumed that the efficacy of ACTH in treating relapses depends on the peptide’s ability to increase endogenous corticosteroid production, evidence from research on the melanocortin system suggests that steroidogenesis may only partly account for ACTH influences. Indeed, the melanocortin peptides (ACTH and α-, β-, γ-melanocyte-stimulating hormones [MSH] and their receptors (MCRs exert multiple actions, including modulation of inflammatory and immune mediator production. Melanocortin receptors are widely distributed within the central nervous system and in peripheral tissues including immune cells (eg, macrophages. This suggests that the mechanism of action of ACTH includes not only steroid-mediated indirect effects, but also direct anti-inflammatory and immune-modulating actions via the melanocortin system. An increased understanding of the role of the melanocortin system, particularly ACTH, in the immune and inflammatory processes underlying relapses may help to improve relapse management.

    To determine factors associated with smoking relapse in men who survived from their first stroke. Data were collected through face to face interviews with stroke patients in the hospital, and then repeated every three months via telephone over the period from 2010 to 2014. Kaplan-Meier method and competing risk model were adopted to estimate and predict smoking relapse rates. The Kaplan-Meier method estimated a higher relapse rate than the competing risk model. The four-year relapse rate was 43.1% after adjustment of competing risk. Exposure to environmental tobacco smoking outside of home and workplace (such as bars and restaurants) ( P =0.01), single ( P <0.01), and prior history of smoking at least 20 cigarettes per day ( P =0.02) were significant predictors of smoking relapse. When competing risks exist, competing risks model should be used in data analyses. Smoking interventions should give priorities to those without a spouse and those with a heavy smoking history. Smoking ban in public settings can reduce smoking relapse in stroke patients.

    Objective To analyse the risk factors of relapse before bone marrow transplantation (BMT) and to present the prognostic information as good as possible.Methods A total of 3142 patients, who underwent the allogeneic blood or bone marrow tran splantation between 1989 and 1997 and were documented in the European Group for Blood and Marrow transplantation (EBMT), were included. Six possible risk factors including type of donor, stage of disease, age, gender, donor@#-recipient sex co mbination and the waiting time from diagnosis to transplation of relapse were co nsidered. The time to relapse was analysed by Kaplan-Meier curves and Coxregre ssion with stratification on prognostic factors that did not satisfy the Proport ional Hazard Assumption.Results An amount of 447 patients relapsed out of all 3142 patients. The relapse rate was 14.2%. Type of donor and stage of disease showed a clear prognostic effect, but failed the proportional hazard assumption. Therefore, the data were stratified on the combination of type of donor and stage of disease. Within these strata a n additional significant effect of age could be observed. Relative risk of age ≥40 vs age <40 was 1.32 (95% confidence interval 1.09-1.59). The prognostic model is summarized graphically.Conclusions The combination of type of donor, stage of disease and age of recipient at transplantation are important prognostic factors for relapse after BMT.

  6. The Value of Fecal Markers in Predicting Relapse in Inflammatory Bowel Diseases

    2018-01-01

    Full Text Available The inflammatory bowel diseases (IBDs are lifelong chronic illnesses that place an immense burden on patients. The primary aim of therapy is to reduce disease burden and prevent relapse. However, the occurrence of relapses is often unpredictable. Current disease monitoring is primarily by way of clinical indices, with relapses often only recognized once the inflammatory episode is established with subsequent symptoms and gut damage. The window between initial upregulation of the inflammatory response and the recognition of symptoms may provide an opportunity to prevent the relapse and associated morbidity. This review will describe the existing literature surrounding predictive indicators of relapse of IBD with a specific focus on fecal biomarkers. Fecal biomarkers offer promise as a convenient, non-invasive, low cost option for disease monitoring that is predictive of subsequent relapse. To exploit the potential of fecal biomarkers in this role, further research is now required. This research needs to assess multiple fecal markers in context with demographics, disease phenotype, genetics, and intestinal microbiome composition, to build disease behavior models that can provide the clinician with sufficient confidence to intervene and change the long-term disease course.

    Full Text Available Abstract Background Diabetes is a common disease with self-management a key aspect of care. Large prospective trials have shown that maintaining glycated hemoglobin less than 7% greatly reduces complications but translating this level of control into everyday clinical practice can be difficult. Intensive improvement programs are successful in attaining control in patients with type 2 diabetes, however, many patients experience glycemic relapse once returned to routine care. This early relapse is, in part, due to decreased adherence in self-management behaviors. Objective This paper describes the design of the Glycemic Relapse Prevention study. The purpose of this study is to determine the optimal frequency of maintenance intervention needed to prevent glycemic relapse. The primary endpoint is glycemic relapse, which is defined as glycated hemoglobin greater than 8% and an increase of 1% from baseline. Methods The intervention consists of telephonic contact by a nurse practitioner with a referral to a dietitian if indicated. This intervention was designed to provide early identification of self-care problems, understanding the rationale behind the self-care lapse and problem solve to find a negotiated solution. A total of 164 patients were randomized to routine care (least intensive, routine care with phone contact every three months (moderate intensity or routine care with phone contact every month (most intensive. Conclusion The baseline patient characteristics are similar across the treatment arms. Intervention fidelity analysis showed excellent reproducibility. This study will provide insight into the important but poorly understood area of glycemic relapse prevention.

    The prognosis for patients multiple myeloma (MM) has improved substantially over the past decade with the development of new, more effective chemotherapeutic agents and regimens that possess a high level of anti-tumor activity. In spite of this important progress, however, nearly all MM patients ultimately relapse, even those who experience a complete response to initial therapy. Management of relapsed MM thus represents a vital aspect of the overall care for patients with MM and a critical area of ongoing scientific and clinical research. This comprehensive manuscript from the International Myeloma Working Group provides detailed recommendations on management of relapsed disease, with sections dedicated to diagnostic evaluation, determinants of therapy, and general approach to patients with specific disease characteristics. In addition, the manuscript provides a summary of evidence from clinical trials that have significantly impacted the field, including those evaluating conventional dose therapies, as well as both autologous and allogeneic stem cell transplantation. Specific recommendations are offered for management of first and second relapse, relapsed and refractory disease, and both autologous and allogeneic transplant. Finally, perspective is provided regarding new agents and promising directions in management of relapsed MM.

    Objective To examine prospectively the natural course of bulimia nervosa (BN) and eating disorder not-otherwise-specified (EDNOS) and test for the effects of stressful life events (SLE) on relapse after remission from these eating disorders. Method 117 female patients with BN (N = 35) or EDNOS (N = 82) were prospectively followed for 72 months using structured interviews performed at baseline, 6- and 12-months, and then yearly thereafter. ED were assessed with the structured clinical interview for DSM-IV, and monitored over time with the longitudinal interval follow-up evaluation. Personality disorders were assessed with the diagnostic interview for DSM-IV-personality-disorders, and monitored over time with the follow-along-version. The occurrence and specific timing of SLE were assessed with the life events assessment interview. Cox proportional-hazard-regression-analyses tested associations between time-varying levels of SLE and ED relapse, controlling for comorbid psychiatric disorders, ED duration, and time-varying personality-disorder status. Results ED relapse probability was 43%; BN and EDNOS did not differ in time to relapse. Negative SLE significantly predicted ED relapse; elevated work and social stressors were significant predictors. Psychiatric comorbidity, ED duration, and time-varying personality-disorder status were not significant predictors. Discussion Higher work and social stress represent significant warning signs for triggering relapse for women with remitted BN and EDNOS. PMID:21448971

    Full Text Available Background. Activity of autoimmune processes had a leading role in the development of relapse of hyperthyroidism. Level of thyroid-stimulating hormone (TSH receptor antibodies is a basic factor that predetermines the relapse and can be used as a criterion to evaluate its development. A research aim was to study the structural and functional state of the thyroid gland, levels of thyroid peroxidase antibodies and TSH receptor antibodies in patients with postoperative relapse of Graves’ disease during antithyroid therapy. Mate­rials and methods. The group of patients consisted of 25 wo­men aged 23 to 73 years (an average of 53.56 ± 2.31 years. The period from the first surgical treatment to the development of relapse of thyrotoxicosis ranged from 1 to 29 years and avera­ged 13.33 ± 1.66 years. Results. It was found that the le­vels of TSH receptor antibodies, which are the main factors in the pathogenesis of Graves’ disease, are not decreased on the background of drug treatment that indicates a lack of perspective of conservative therapy for the post-operative relapse of this disease. Conclusions. When the state of medication compensation for thyrotoxicosis is achieved, it is recommended to conduct the therapy with I131 or surgical treatment of the relapse of Graves’ disease.

    Full Text Available Objective: this research studied the relation between cluster B personality disorders and major depression disorder with relapse. Materials & Methods: In this analytical and comparative study, samples consisted of the major depressive disorders patients that had experienced major depression through 5 years ago and were experiencing partial remission in research time. Samples were selected by non probability sampling in outpatient centers. The patients with more than two relapses were assigned as case group and the patients without any relapse were assigned as control group (two groups on the base of demographic in formations were matched. They completed BDI_II and SCID_II to assess cluster B personality disorders, and a questionnaire made by researcher to gather information’s. Results: Comorbidity of borderline personality disorder (P<0.001 and narcissitic personality disorder (P=0.016 with depression in patient with relapse of the depression is more significantly than patients with first episode of depression, but comorbidity of exhibitive personality disorder with depression and relapse had no significant difference between two groups (P=0.401. Conclusion: according to the relationship between narcissistic and borderline personality disorders and the role of them in relapse of depression, for making an effective psychotherapy for depression, it is necessary to consider personality beside special symptoms.

    To assess the efficacy of levamisole in frequently relapsing nephrotic syndrome and steroid-dependent nephrotic syndrome. Retrospective analysis of hospital case records. Pediatric nephrology department of a tertiary referral pediatric hospital. 62 children with frequently relapsing nephrotic syndrome and 35 children with steroid-dependent nephrotic syndrome. Case records of children who were diagnosed as steroid-dependant or frequently-relapsing nephrotic syndrome from June 2004 to June 2011, were reviewed. Levamisole was given daily (2 mg/kg/d) along with tapering doses of alternate day steroids after remission on daily steroids. Levamisole was effective in 77.3% children with a better (80.6%) efficacy in frequently relapsing nephrotic syndrome. A total of 34 children completed 1 year follow-up post levamisole therapy. The cumulative mean (SD) steroid dose 1-year before therapy was 4109(1154) mg/m2 and 1-year post therapy was 661 (11) mg/m2 (P<0.001). The relapses were also less during the period of post-levamisole therapy. Levamisole is an effective alternative therapy in frequently relapsing and steroid-dependent nephrotic syndrome.

    Spinal cord compression (SCC) is an unusual sequale of extra-medullary hematopoiesis (EMH). We report a patient diagnosed with β-thalassemia intermedia at the age of 7 years presenting as a 24-year-old with symptoms suggestive of paraparesis. MR imaging revealed long masses of EMH opposite T5-T11 and L5-S2 vertebrae with cord compression at T6 vertebrae. Patient was treated with external beam radiotherapy (EBRT) to a low dose of 20 Gy in 10 fractions over 2 weeks. The patient had symptomatic relief of paraparesis by the 5th fraction and nearly regained full power in bilateral lower limbs by EBRT conclusion. Patient was begun on hydroxyurea post EBRT and was symptom free at 2-month follow up. With a follow-up of 18 months so far, he remains asymptomatic and free of recurrence. MRI correlation of pre-EBRT, post-EBRT and at first follow-up showed a significant reduction in the size of EMH, increase in diameter of spinal canal post EBRT but a persistent edema which had no clinical manifestation. Though there was a 58% drop in leukocyte count by the end of EBRT, there was no leukocytopenia. We suggest that EBRT should be treatment of choice for SCC due to EMH as it produces as rapid and durable response with minimal acute hematological side-effects.

    Novel therapies with unique new targets are needed for patients who are relapsed/refractory to current treatments for multiple myeloma. Ibrutinib is a first-in-class, once-daily, oral covalent inhibitor of Bruton tyrosine kinase, which is overexpressed in the myeloma stem cell population. This study examined various doses of ibrutinib ± low-dose dexamethasone in patients who received ≥2 prior lines of therapy, including an immunomodulatory agent. Daily ibrutinib ± weekly dexamethasone 40 mg was assessed in 4 cohorts using a Simon 2-stage design. The primary objective was clinical benefit rate (CBR; ≥minimal response); secondary objectives included safety. Patients (n = 92) received a median of 4 prior regimens. Ibrutinib + dexamethasone produced the highest CBR (28%) in Cohort 4 (840 mg + dexamethasone; n = 43), with median duration of 9·2 months (range, 3·0-14·7). Progression-free survival was 4·6 months (range, 0·4-17·3). Grade 3-4 haematological adverse events included anaemia (16%), thrombocytopenia (11%), and neutropenia (2%); grade 3-4 non-haematological adverse events included pneumonia (7%), syncope (3%) and urinary tract infection (3%). Ibrutinib + dexamethasone produced notable responses in this heavily pre-treated population. The encouraging efficacy, coupled with the favourable safety and tolerability profile of ibrutinib, supports its further evaluation as part of combination treatment. © 2018 The Authors.

    To evaluate the efficacy of methotrexate (MTX) and the effect of its withdrawal on relapse rate of uveitis associated with juvenile idiopathic arthritis (JIA). Retrospective case series. Data of 22 pediatric JIA patients who were being treated with MTX for active uveitis were studied retrospectively. Relapse rate after the withdrawal of MTX was established. Anterior chamber (AC) inflammation, topical steroid use during the first year of MTX treatment, and associations of relapses after the withdrawal were evaluated statistically. Duration of MTX treatment and its withdrawal was determined individually in collaboration with a rheumatologist with an intention to continue the treatment for at least 1 year and to withdraw in case of inactivity of uveitis and arthritis. Inactivity of uveitis was defined as the presence of ≤0.5+ cells in the AC. Eighteen patients (18/22; 82%) showed improvement of their uveitis with a significant decrease in activity of AC inflammation after a minimal period of 3 months of MTX treatment. A topical steroid-sparing effect was observed when MTX was administered for a period of 3 to 9 months. MTX was discontinued because of inactive uveitis in 13 patients. In 9 patients (8/13; 69%) a relapse of uveitis was observed after a mean time of 7.5 months (± SD 7.3). Six patients (6/13; 46%) had a relapse within the first year after the withdrawal. Relapse-free survival after withdrawal of MTX was significantly longer in patients who had been treated with MTX for more than 3 years (P = .009), children who were older than 8 years at the moment of withdrawal (P = .003), and patients who had an inactivity of uveitis of longer than 2 years before withdrawal of MTX (P = .033). Longer inactivity under MTX therapy was independently protective for relapses after the withdrawal (hazard ratio = 0.07; 95% confidence interval 0.01-0.86; P = .038), which means that 1-year increase of duration of inactive uveitis before the withdrawal of MTX results in a

    Each year, 5000-6000 individuals undergo orthotopic liver transplantation (OLT) in the United States, and of these, nearly 18% have alcoholic liver disease. Relapse to alcohol occurs in more than 40% of patients with OLT for alcoholic liver disease. We sought to identify factors that predict relapse to alcohol or medication nonadherence following OLT in patients with alcoholic liver disease and to review what randomized clinical interventions have addressed these factors following OLT. Our hypothesis was that there would be factors before and after OLT that predict relapse to alcohol following OLT, and that these, if targeted, might improve sobriety and associated outcomes of adherence with medications and appointments. We performed a review (focusing on articles published since 2004) with PubMed and MEDLINE searches using the following search terms: liver transplantation, recidivism, alcohol relapse, and predictors of alcohol relapse. We supplemented the online searches with manual reviews of article reference lists and selected relevant articles for further review by author consensus. In largely white populations, prospective studies document that shorter length of pretransplantation sobriety is a significant predictor of time to first drink and time to binge use. Presence of psychiatric comorbidity, high score on standardized High-risk Alcoholism Relapse Scale, and diagnosis of Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) alcohol dependence are predictive of posttransplantation alcohol relapse. Pretransplantation alcohol use history variables (e.g., family history of alcoholism) reliably discriminate between complete abstainers and those who drink, while medical and psychosocial characteristics at early post-liver transplantation period (e.g., more bodily pain) maximally discriminate patterns of alcohol use. Alcoholic individuals with early-onset, rapidly accelerating moderate use and early-onset, continuously increasing heavy use have

    The aim of the present study was to monitor long term antithyroid drug treatments and to identify prognostic factors for Graves' disease (GD). A total of 306 patients with GD who were referred to the Endocrinology Clinic at Weifang People's Hospital (Weifang, China) between August 2005 and June 2009 and treated with methimazole were included in the present study. Following treatment, patients were divided into non-remission, including recurrence and constant treatment subgroups, and remission groups. Various prognosis factors were analyzed and compared, including: Patient age, gender, size of thyroid prior to and following treatment, thyroid hormone levels, disease relapse, hypothyroidism and drug side-effects, and states of thyrotropin suppression were observed at 3, 6 and 12 months post-treatment. Sixty-five patients (21.2%) were male, and 241 patients (78.8%) were female. The mean age was 42±11 years, and the follow-up was 31.5±6.8 months. Following long-term treatment, 141 patients (46%) demonstrated remission of hyperthyroidism with a mean duration of 18.7±1.9 months. The average age at diagnosis was 45.6±10.3 years in the remission group, as compared with 36.4±8.8 years in the non-remission group (t=3.152; P=0.002). Free thyroxine (FT)3 levels were demonstrated to be 25.2±8.9 and 18.7±9.4 pmol/l in the non-remission and remission groups, respectively (t=3.326, P=0.001). The FT3/FT4 ratio and thyrotrophin receptor antibody (TRAb) levels were both significantly higher in the non-remission group (t=3.331, 3.389, P=0.001), as compared with the remission group. Logistic regression analysis demonstrated that elevated thyroid size, FT3/FT4 ratio and TRAb at diagnosis were associated with poor outcomes. The ratio of continued thyrotropin suppression in the recurrent subgroup was significantly increased, as compared with the remission group (P=0.001), as thyroid function reached euthyroid state at 3, 6 and 12 months post-treatment. Patients with GD exhibiting

    Technetium thyroid uptake (TTU) is not inhibited by antithyroid drugs (ATD) and reflects the degree of thyroid stimulation. We intended to predict the relapse rate from hyperthyroidism based on TTU measurement. Out of 44 initially enrolled subjects, 38 patients aged 41.6 ± 14.6 with Graves disease (duration: 84 ± 78 months) completed the study. TTU was performed with 40-second imaging of the neck and mediastinum 20 minutes after injection of 1 mCi technetium-99m pertechnetate. TTU was measured as the percentage of the count of activity accumulated in the thyroidal region minus the mediastinal background uptake to the count of 1 mCi technetium-99m under the same acquisition conditions. Then methimazole was stopped and patients were followed. The optimal TTU cutoff value for Graves relapse prediction was calculated using Youden's J statistic. Hyperthyroidism relapsed in 11 (28.9%) patients 122 ± 96 (range: 15-290) days post-ATD withdrawal. The subjects in remission were followed for 209 ± 81 days (range: 88-390). TTU was significantly higher in patients with forthcoming relapse (12.0 ± 8.0 vs. 3.9 ± 2.0, P = .007). The difference was significant after adjustment for age, sex, history of previous relapse, disease duration, and thyroid-stimulating hormone (TSH) levels before withdrawal. The area under the receiver operative characteristic (ROC) curve was 0.87. The optimal TTU cutoff value for classification of subjects with relapse and remission was 8.7 with sensitivity, specificity, and positive and negative predictive value of 73%, 100%, 100%, and 90%, respectively (odds ratio [OR] = 10.0; 95% confidence interval [CI]: 3.4-29.3). TTU evaluation in hyperthyroid patients receiving antithyroid medication is an accurate and practical method for predicting relapse after ATD withdrawal. ATD = antithyroid drugs RIU = radio-iodine uptake TSH = thyroid-stimulating hormone TSI = thyroid-stimulating immunoglobulin TTU = technetium thyroid uptake.

    Full Text Available In Africa, relapsing fevers caused by ectoparasite-borne Borrelia species are transmitted by ticks, with the exception of Borrelia recurrentis, which is a louse-borne spirochete. These tropical diseases responsible for mild to deadly spirochetemia. Cultured B. crocidurae, B. duttonii and B. hispanica circulate alongside at least six species which have not yet been cultured in vectors. Direct diagnosis is hindered by the use of non-specific laboratory tools. Indeed, microscopic observation of Borrelia spirochaeta in smears of peripheral blood taken from febrile patients lacks sensitivity and specificity. Although best visualised using dark-field microscopy, the organisms can also be detected using Wright-Giemsa or acridine orange stains.. PCR-based detection of specific sequences in total DNA extracted from a specimen can be used to discriminate different relapsing fever Borreliae. In our laboratory, we developed a multiplex real-time PCR assay for the specific detection of B. duttonii/recurrentis and B. crocidurae: Multispacer Sequence Typing accurately identified cultured relapsing fever borreliae and revealed diversity among them. Other molecular typing techniques, such as multilocus sequence analysis of tick-borne relapsing fever borreliae, showed the potential risk of human infection in Africa. Recent efforts to culture and sequence relapsing fever borreliae have provided new information for reassessment of the diversity of these bacteria. Recently, matrix-assisted laser desorption ionization time-of-flight mass spectrometry has been reported as a means of identifying cultured borreliae and of identifying both vectors and vectorised pathogens such as detecting relapsing fever borreliae directly in ticks. The lack of a rapid diagnosis test restricts the management of such diseases. We produced monoclonal antibodies against Borrelia crocidurae in order to develop cheap assays for the rapid detection of relapsing fever borreliae. In this paper
