peripheral t-cell lymphomas are a group of heterogeneous disorders and according to who classification, are categorized into nodal and extranodal forms. nk/t-cell lymphoma, nasal type, is a subtype of extranodal peripheral t-cell lymphoma and commonly presents as a midfacial destructive lesion. this disorder is more prevalent in asia and south america and has a strong association with epstein b...

The ontogenesis of the nasal cavity has been described in many mammalian species. The situation is different with reptiles, despite the fact that they have become relatively common as pets. In this study we focused on the ontogenesis of the olfactory epithelium, as well as other types of epithelia in the nasal cavity of pre-hatched green iguanas (Iguana iguana). Collection of samples began from...

UNLABELLED Acoustic rhinometry is an objective method to determine nasal cavity geometry. The technique is based on sound wave reflexion analysis in the nasal cavity, and determines crossectional areas as a function of distance as well as volume. AIM The purpose of this study is to analyse nasal cavity volume changes caused by functional endoscopic sinus surgery (FESS) in adults with chronic ...

The functions of the nasal cavity are closely related to its structure. In this study the three-dimensional finite element models were established based on the clinical data of twenty-four volunteers to study the influence of nasal structure on nasal functions of heating the inhaled airflow. Numerical simulations mainly concerning the airflow distribution and the airflow temperature are perform...

OBJECTIVE To investigate the impact of airflow communication between bilateral nostril sides on nasal ventilation. In addition, we try to validate the efficacy of the Draf III procedure from the aerodynamics perspective. METHODS One health model and two disease models were constructed. These included 2 patients with nasal septum perforation and 1 patient who received the Draf III procedure. W...

IgG4RSD affecting the nasal cavity and paranasal sinuses is extremely rare. A 71-year-old man presented with an invasive mass in the nasal cavity and paranasal sinuses that was confirmed by immunostaining to be IgG4RSD. The occurrence of this disease in the nasal cavity and paranasal sinuses can resemble a malignant tumor on diagnostic imaging.

The nasal cavity is susceptible to chemically induced injury as a result of exposure to inhaled irritants. Some responses of the nasal mucosa to inhaled toxicants are species specific. These species-related differences in response may be due to variations in structural, physiologic, and biochemical factors, such as gross nasal cavity structure, distribution of luminal epithelial cell population...

The nasal cavity volume and the temperature of the nasal mucosa are considered to be the most important predictors of nasal conditioning. The aim of this study was to assess the relationship between the intranasal degree of water vapour saturation of inhaled air and nasal patency. Intranasal humidity values at different locations within the nasal cavity of 15 healthy subjects were compared to n...

The aim of this study was to investigate the occurrence of bacterial cross-contamination between the nasal cavity and leg ulcers. Sixteen patients were included in the study. Staphylococcus aureus was isolated from the leg ulcer of 13 patients and 6 of these patients also harboured S. aureus in the nasal cavity. Klebsiella oxytoca was found in the ulcer and the nasal cavity of one patient. PFGE...

OBJECTIVE The nasal cavity is an uncommon site for metastasis to develop and thus metastases arising from breast cancer are rarely observed. We report a case of a 61-year-old female with two-year history of breast cancer who presented with a nasal cavity that was diagnosed as metastatic breast carcinoma by histopathological analysis of the nasal cavity specimen. METHODS We reviewed the clinic...
