Case report: A rare case of Rosai-Dorfman-Destombes disease after the COVID-19 infection.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is known to cause immune dysregulation and, therefore, has varied and often rare presentations. Rosai-Dorfman-Destombes disease (RDD) is an unusual non-Langerhans cell (non-LC) histiocytosis presenting with massive lymphadenopathy and various systemic symptoms. A 55-year-old Asian-American woman with no significant medical history or recent use of new drugs initially presented with cervical lymphadenopathy and urticarial rash 1 week after receiving the COVID-19 messenger RNA (mRNA) vaccine (Moderna, mRNA-1273) against SARS-CoV-2.

Gradient H-Bonding Supports Highly Adaptable and Rapidly Self-Healing Composite Binders with High Ionic Conductivity for Silicon Anodes in Lithium-Ion Batteries.

An ideal binder for high-energy-density lithium-ion batteries (LIBs) should effectively inhibit volume effects, exhibit specific functional properties (e.g., self-repair capabilities and high ionic conductivity), and require low-cost, environmentally friendly mass production processes.

Robotic distal ureterectomy and re-implant for obstructing metastatic melanoma - surgical considerations in the palliative setting.

Non-urothelial malignant ureteral obstruction (MUO) causes hydronephrosis, renal damage and infectious sequelae. The overall condition, symptoms, and plans for systemic therapy inform urologic intervention. In well-selected cases, there is a role for definitive reconstruction.

Contained abdominal aortic rupture secondary to follicular lymphoma invasion.

An 87-year-old woman with grade IIIb follicular lymphoma treated with rituximab had presented with nausea, emesis, and chest pain of 1 day duration. She was found to have a contained abdominal aortic rupture secondary to follicular lymphoma invasion. She safely and successfully underwent emergent endovascular aortic repair.

COVID-19-associated thrombotic angiopathy improved after plasma exchange.

Utilization of therapeutic plasma exchange in select patients with COVID-19 microangiopathy may provide useful treatment by modulation of inflammatory cytokines and coagulation cascade to maintain homeostasis.

Clinical Determinants Differentiating the Severity of SARS-CoV-2 Infection in Cancer Patients: Hospital Care or Home Recovery.

Cancer patients may carry a worse prognosis with SARS-CoV-2 infection. Most of the previous studies described the outcomes of hospitalized cancer patients. We aimed to study the clinical factors differentiating patients requiring hospital care vs.

Chemotherapy Treatment Modifications During the COVID-19 Outbreak at a Community Cancer Center in New York City.

Purpose: As a result of their immunocompromised status associated with disease and treatment, patients with cancer face a profound threat for higher rates of complications and mortality if they contract the coronavirus disease 2019 infection. Medical oncology communities have developed treatment modifications to balance the risk of contracting the virus with the benefit of improving cancer-related outcomes.

Methods: We systemically examined our community cancer center database to display patterns of change and to unveil factors that have been considered with each decision.

A case series of Kimura's disease: a diagnostic challenge.

Kimura's disease (KD) is a rare, benign disorder characterized by subcutaneous masses with regional lymph-node enlargement. It is considered to be due to chronic inflammation of unclear etiology. Most cases have been reported in young, 20-30-year-old men of Asian descent.

Prevalence and characteristics of hereditary non-polyposis colorectal cancer (HNPCC) syndrome in immigrant Asian colorectal cancer patients.

Background: The prevalence of Hereditary Non-Polyposis Colorectal Cancer (HNPCC) is 2 to 5% in the Caucasian population. HNPCC is caused by genomic mutations in DNA mismatch repair genes (MMR), namely MLH1, MSH2, MSH6, PMS2, and EPCAM. A non-hereditary, acquired process of hypermethylation of the MLH1 promoter can also lead to silencing of MLH1 protein expression.

Rare Case of Spinal Cord Compression as Initial Presentation of Thymic Carcinoma.

Thymic carcinomas are rare aggressive cancers with limited clinical trial data. Its usual treatment is surgical resection with variable response to chemotherapy and radiation. It usually presents as anterior mediastinal mass with late sequela of metastases to the lymph nodes, pleura and bones.

Systemic Cystic Angiomatosis Mimicking Metastatic Cancer: A Case Report and Review of the Literature.

Systemic cystic angiomatosis is a rare benign disorder due to the maldeveloped vascular and lymphatic system with less than 50 cases reported in literature so far. We report here a case of systemic cystic angiomatosis (SCA) with multisystem involvement affecting the neck, thyroid, thoracic cavity, and skeletal system. The patient initially presented in her 4th decade of life with isolated lymphangioma in the neck requiring surgery.

Response of advanced stage recurrent lymphoepithelioma-like carcinoma to nivolumab.

Lymphoepithelioma-like carcinoma (LELC) of lung is a rare tumor that is mostly reported in south-east Asian countries. The surgical removal is curative in the early stages but there is no consensus on the choice of chemotherapy for the treatment of advanced stage tumors. Most of the data on chemotherapy are based on small case series and retrospective studies.

Anti-claudin 18.2 antibody as new targeted therapy for advanced gastric cancer.

Targeted therapy and immunotherapy have revolutionized treatment of various cancers in the past decade. Despite targeted therapy with trastuzumab in Her2-positive gastric cancer patients, survival has been dismal, mostly due to disease progression and toxicity related to the treatments. One area of active development is looking for ideal monoclonal antibodies (IMAB) specific to the proteins only on the tumor and hence avoiding unnecessary side effects.

The performance of NLST screening criteria in Asian lung cancer patients.

Background: Screening high-risk individuals with low dose CT decreased lung cancer mortality in the National Lung Screening Trial (NLST), but the validity of directly extrapolating these results to an Asian population is unclear. Using statistical models on Surveillance, Epidemiology and End Result (SEER) data, 27% of lung cancer patients in the United States were estimated to meet the screening criteria. This study aims to evaluate the performance of the NLST criteria in Asian lung cancer patients and to examine the characteristics of those who did not meet the criteria.

A Unique Case of Classic Kaposi's sarcoma restricted to the toes.

Background: Kaposi's sarcoma associated-herpesvirus causes all forms of Kaposi's sarcoma, and six major subtypes have been described based on the amino acid sequences of the open reading frame K1.

Main Observation: A 71-year-old man from China, HIV negative, presented with nodules on the dorsal aspect of his toes. Biopsy confirmed the diagnosis of Kaposi's sarcoma and virology studies of his blood and saliva confirmed the presence of Kaposi's sarcoma associated-herpesvirus infection.

A Chinese version of the Spiritual Needs Assessment for patients survey instrument.

Context: Unmet spiritual needs have been associated with decreased patient ratings of quality of care, satisfaction, and quality of life. Few instruments exist to measure spiritual needs particularly among non-English speaking patients in the U.S.

Immunogenicity of an inactivated monovalent 2009 influenza A (H1N1) vaccine in patients who have cancer.

Background: The immune response of patients who have cancer, who may be receiving immunosuppressive therapy, is generally considered to be decreased. This study aimed to evaluate the immune response of cancer patients to the 2009 influenza A (H1N1) vaccine.

Patients And Methods: We conducted a prospective single site study comparing the immune response after H1N1 vaccination of healthy controls (group A), patients who had solid tumors and were taking myelosuppressive chemotherapy (group B), patients who had solid tumors and were taking nonmyelosuppressive or no treatment (group C), and patients who had hematologic malignancies (group D).

Isolated sternal involvement in breast cancer: is it truly stage IV disease?

Purpose: There is no consensus regarding treatment for patients with breast cancer and isolated sternal involvement. Though classified as AJCC stage IV, this group of patients may have prolonged distant disease free survival.

Patients And Methods: Retrospective case series of 8 patients with isolated sternal recurrence.

Clinical outcomes in extracranial tumor sites and unusual toxicities with concurrent whole brain radiation (WBRT) and Erlotinib treatment in patients with non-small cell lung cancer (NSCLC) with brain metastasis.

Background: Thirty percent of newly diagnosed NSCLC patients present with synchronous brain metastases, most of whom are treated with whole brain radiation. Systemic chemotherapy is usually avoided during WBRT due to concerns regarding toxicity. However, concurrent administration of targeted agents, such as Erlotinib, during WBRT may address systemic disease without causing toxicity.

Subcutaneous panniculitis-like T-cell lymphoma in a patient with long-term remission with standard chemotherapy.

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is a very rare postthymic T-cell non-Hodgkin's lymphoma with poor prognosis. There is not a standard treatment for this disease. Here we describe the first case of SPTL with unusual periorbital involvement, pancytopenia, hepatic dysfunction and coagulopathy, which was successfully treated with a chemotherapy regimen of cyclophosphamide, hydroxydaunomycin (doxorubicin), Oncovin (vincristine) and prednisone (CHOP).

[The registration of false teeth and the others].

[Adverse events of medical devices and the role of the government].

The concept of medical devices adverse events is introduced in the paper. The contents of surveillance of adverse events are discussed and the government's role in the surveillance is presented as well.

Retinal vein thrombosis as the presenting symptom of essential thrombocythemia.

Visual loss resulting from retinal vascular disorders can be the presenting sign of serious systemic disease. Associations between retinal vein thrombosis and other systemic disorders have been well documented, but a comprehensive literature search failed to reveal any report of essential thrombocythemia as a cause of central retinal vein thrombosis. We describe the first young female patient with symptomatic visual loss due to central retinal vein thrombosis as her presenting symptom of essential thrombocythemia.
