Background & Objective: Primary non-Hodgkin's lymphoma (NHL) of the nasal cavity has unique clinicopathologic features, and optimal treatment regimen remains unclear. This study was to summarize the clinical features, treatment outcomes, and prognostic factors of primary NHL of the nasal cavity at early stage.
Methods: Records of 108 patients with primary NHL of the nasal cavity, consecutively treated at Cancer Center, Sun Yat-sen University from Jun. 1990 to Sep. 2004, were reviewed. All diagnoses were confirmed with pathology and immunochemistry. Seven cases were of B-cell phenotype. Survival prognostic factors were analyzed by Kaplan-Meier method and Cox regression model with SPSS12.0 software.
Results: Median follow-up time for survived patients was 41 months. The overall complete remission (CR) rate after primary treatment was 67.6%, and CR rates were 80.2% for the patients received radiochemotherapy and 29.6% for the patients received chemotherapy alone. There were evidences indicating systemic relapse in 33 (30.6%) patients. With regard to the control of local, regional, and systemic failure, radiochemotherapy was better than chemotherapy alone. The 5-year overall survival rate was 50.0% for all patients. Both univariate analysis and multivariate analysis showed that pre-treatment history of more than 3 months, primary lesion limited in the nasal cavity, CR after primary treatment, and radiochemotherapy were favorable prognostic factors.
Conclusions: Nasal cavity is frequently involved by peripheral T- and NK-cell lymphomas. Pre-treatment history of disease, extent of primary lesion involvement, and response to the primary treatment may be independent prognostic factors.

Background: Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-malignant disorder characterized by excessive proliferation of histiocytes, the cause of which remains unknown. Although the lymph nodes are the most commonly affected site, some patients may present with extranodal involvement, particularly in the skin, nasal cavity, eyes, and bones. In this report, we aim to present a unique case of RDD with pleural involvement in a 61-year-old patient.

Background: Glanders and melioidosis are contagious zoonotic diseases caused by Burkholderia mallei and B. pseudomallei, respectively. Bacterial isolation and polymerase chain reaction (PCR) have been used to detect these bacteria in animals suspected of infection; however, both methods require skilled experimental techniques and expensive equipment.

Viral infections are characterized by dispersal from an initial site to secondary locations within the host. How the resultant spatial heterogeneity shapes within-host genetic diversity and viral evolutionary pathways is poorly understood. Here, we show that virus dispersal within and between the nasal cavity and trachea maintains diversity and is therefore conducive to adaptive evolution, whereas dispersal to the lungs gives rise to population heterogeneity.

Introduction: Rhabdomyosarcoma (RMS) originates from undifferentiated mesenchymal cells that give rise to striated muscles. The symptoms of para-meningeal RMS often resemble those of allergic rhinosinusitis, including nasal congestion, mucus discharge, headache, and occasional nosebleeds. We report a child with atypical clinical presentation of ocular hypertropia secondary to para-meningeal RMS.

By addressing patients' physical, psychological, social, cultural, and environmental comfort needs holistically, Kolcaba's Comfort Theory raises the standard of care and increases patient satisfaction. This study explored the combined application of these nursing models during the perioperative period for patients undergoing nasal deformity correction surgery. 92 patients undergoing nasal deformity correction at the Seventh Affiliated Hospital of Sun Yat-sen University were randomly divided into two groups: the conventional group (46 patients), which received standard perioperative nursing care, and the experimental group (46 patients), which received concept map thinking nursing combined with Kolcaba's comfort nursing intervention during the perioperative period.
