Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening disorders. The incidences, mortality and cost of SJS and TEN in US adults are not well-characterized. We analyzed data from the 2009-2012 Nationwide Inpatient Sample, containing a representative 20% sample of all hospitalizations in the US. SJS, SJS/TEN and TEN were identified by a validated algorithm using ICD-9- CM codes. The mean incidences of SJS, SJS/TEN and TEN were 9.3, 1.6, and 1.9 per million people per year, respectively...

We sought to determine the comorbid health conditions and inpatient mortality associated with pemphigus in a U.S. inpatient cohort. The 2002-2012 Nationwide Inpatient Sample, which contains a representative 20% stratified sample of all inpatient hospitalizations in the US, was analyzed. Comorbidities were determined through ICD-9-CM codes. Survey weighted multivariate logistic regression models controlling for demographic factors were constructed to determine the association of pemphigus with various comorbidities...

Centrofollicular B Cell lymphomas constitute 25% of non-Hodgkin lymphomas that originate in the skin. They are the second in frequency of those lymphomas with extranodal location after gastrointestinal B lymphomas. The primary cutaneous centrofollicular lymphoma is characterized by the neoplastic proliferation of centrocytes and centroblasts confined to the skin. The prognosis is considered excellent with low probability of extracutaneous dissemination. We present a patient recently diagnosed in our unit with a good response to radiotherapy and complete resolution of the tumor with mild atrophy of the site...

Anaplastic large-cell lymphomas (ALCLs) are agroup of CD30-positive non-Hodgkin lymphomasthat are linked by common morphologic andimmunophenotypic features but have varyingclinical and genetic characteristics. The World HealthOrganization classification currently recognizes threesubtypes of ALCL: systemic anaplastic lymphomakinase-positive ALCL, systemic anaplastic lymphomakinase-negative (ALK-) ALCL, and primary cutaneousALCL. Here we present a 42-year-old man with ahistory of systemic ALK- ALCL, who was in remissionfor six months before relapsing with skin-limitedanaplastic large-cell lymphoma...

Non-Hodgkin lymphoma is the second most common neoplasm of the head and neck after squamous cell carcinoma. However, it accounts for only 3.5% of all malignancies of the oral cavity. Oral lesions are often a component of disseminated disease process that may involve regional lymph nodes or may at times represent the primary extra nodal form of the disease. Although, isolated oral lymphoma in adults is extremely rare, this paper presents a patient with Burkitt lymphoma in an adult male with atypical clinical presentation primarily involving the oral soft tissue...

BACKGROUND: Novel agents are changing the treatment of relapsed or refractory Hodgkin lymphoma (HL). Nevertheless, high-dose chemotherapy and autologous stem-cell transplantation (ASCT) are considered standard of care in eligible patients. To identify patients who could benefit most from novel therapeutic approaches, we investigated a comprehensive set of risk factors for survival after ASCT. METHODS: In this multinational prognostic multivariable modeling study, 23 potential risk factors (RF) were retrospectively evaluated in HL patients from nine prospective trials with multivariable Cox proportional hazards regression analyses (part I)...

Background: The phosphatidylinositol-3-kinase delta (PI3Kδ) inhibitor idelalisib has been shown to block downstream intracellular signaling, reduce the production of prosurvival chemokines and induce apoptosis in classical Hodgkin lymphoma (HL) cell lines. It has also been shown to inhibit regulatory T cells and myeloid-derived suppressor cells in other tumor models. We hypothesized that inhibiting PI3Kδ would have both direct and indirect antitumor effects by directly targeting the malignant cells as well as modulating the inflammatory microenvironment...

Vascular endothelial growth factor (VEGF) plays an important role in angiogenesis and progression of cancer and its expression was associated with gene polymorphisms. Since the impact of polymorphisms of the VEGF on non-Hodgkin lymphoma prognosis has not been fully elucidated, we investigated 149 diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) at the National Cancer Center, Korea. Five polymorphisms were analyzed with clinical characteristics as well as international prognostic index (IPI)...

Extranodal lymphomas are quite rare, and they usually present as non-Hodgkin lymphomas. The most common localization is the gastrointestinal tract, mainly the stomach - primary gastric lymphoma; histologically, diffuse large B-cell lymphoma (DLBCL) is the most frequent type. The diagnosis is established based on endoscopic examination with biopsy of the tumor. It is an aggressive tumor, highly chemosensitive, which is why primary systemic chemotherapy is indicated in early, as well as late, stages of the disease...

REVIEW
Sohita Dhillon
Obinutuzumab (Gazyva(®), Gazyvaro(®)) is a recombinant, monoclonal, humanized and glycoengineered, type II, anti-CD20, IgG1 antibody. It has recently been granted an additional indication for the treatment of patients with follicular lymphoma who relapsed after, or are refractory to, a rituximab-containing regimen. In the primary analysis of the large, phase III GADOLIN study, induction therapy with obinutuzumab plus bendamustine followed by obinutuzumab maintenance prolonged progression-free survival (PFS) to a statistically significant extent relative to induction with bendamustine monotherapy in patients with indolent non-Hodgkin's lymphoma (iNHL)...

Non-Hodgkin lymphomas (NHL) are a heterogeneous group of hematologic malignancies typically treated with multiagent chemotherapy. Rarely, spontaneous remissions can be observed, particularly in more indolent subtypes. The prognosis of aggressive NHL can be predicted using clinical and histopathologic factors. In aggressive B-cell NHL, the importance of MYC and BCL2 proto-oncogene coexpression (as assessed by immunohistochemistry) and high-grade histologic features are particularly noteworthy. We report a unique case of spontaneous remission in a patient with an aggressive B-cell NHL which harbored high-risk histopathologic features, including MYC protein expression at 70-80%, BCL2 protein expression, and morphologic features suggestive of high-grade B-cell lymphoma, NOS (formerly B-cell lymphoma unclassifiable with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma [BCLU])...

BACKGROUND Primary pulmonary diffuse large B cell lymphoma (DLBCL) is extremely rare neoplasm representing only 0.5-1% of primary pulmonary malignancies. These patients usually have non-specific clinical presentation and radiological findings. Therefore, it is important to increase awareness of this rare disease, as the correct characterization of the tumors will have therapeutic and prognostic implications. CASE REPORT We present the case of a middle-aged Hispanic woman with chronic cough and an abnormal chest X-ray revealing a lung mass, who was found to have primary pulmonary DLBCL...

Plasmablastic lymphoma, a rare highly aggressive non-Hodgkin's lymphoma subtype, often associated with HIV infection, is a close differential diagnosis of plasmablastic myeloma. The 2 conditions may be morphologically and immunophenotypically identical. However, differentiating between the 2 conditions is critical for adequate patient management. Herein, we describe an unusual case of plasmablastic myeloma with biclonal gammopathy which was initially diagnosed as plasmablastic lymphoma based on lymph node biopsy and immunohistochemistry (IHC) results...

Classical Hodgkin lymphoma (cHL) is the most common hematological malignancy in young adults and can be cured in most cases. However, relapsed and refractory Hodgkin lymphoma, certain patient groups, such as elderly patients, and toxicity of first-line treatment still pose significant challenges. Consequently, new treatment options are needed. Recently, many new treatment concepts have been evaluated in clinical trials. Targeted drug-antibody conjugates and immune checkpoint inhibitors have decisively changed treatment approaches...

Electrical activity is the foundation of the neural system. Coding theories that describe neural electrical activity by the roles of action potential timing or frequency have been thoroughly studied. However, an alternative method to study coding questions is the energy method, which is more global and economical. In this study, we clearly defined and calculated neural energy supply and consumption based on the Hodgkin-Huxley model, during firing action potentials and subthreshold activities using ion-counting and power-integral model...
